Description

Technical Field

[0001] This invention relates to cooking equipment. Background Technology

[0002] Cooking equipment, as a type of household appliance used for cooking food, is a device installed in the kitchen space to cook food according to the user's intentions. Such cooking equipment can be classified into various types based on the heat source or its form, and the type of fuel used.

[0003] If cooking equipment is classified according to the way food is cooked, it can be divided into open and closed cooking equipment based on the shape of the space where the food is placed. Closed cooking equipment includes ovens and microwave ovens, while open cooking equipment includes stovetops and cooktops.

[0004] A closed-system cooking appliance is a cooking appliance that cooks food by covering the space where the food is located and heating the covered space. A closed-system cooking appliance provides a cooking chamber, which is a space covered when food is placed and is to be cooked. Such a cooking chamber effectively forms the space for cooking food.

[0005] Depending on the type of heat source, the enclosed cooking equipment can be divided into gas ovens and electric ovens. Gas ovens use gas as fuel and supply gas to multiple burners to ignite the gas, thereby cooking food through the flames produced by the combustion of the supplied gas. Unlike gas ovens, electric ovens use electricity as a heat source to operate multiple heaters and utilize the heat radiated from the heaters to cook food.

[0006] Electric ovens are gaining popularity due to their faster cooking speed, higher thermal efficiency, and better stability compared to gas ovens. Furthermore, electric ovens are easier to miniaturize than gas ovens, leading to the release of smaller, mini-oven models (hereinafter referred to as "mini ovens") on the market.

[0007] Because of its small size, the mini oven is not suitable for cooking larger foods, but it is suitable for baking or heating small amounts of food that are not suitable for use with a large-capacity oven.

[0008] In particular, the advantage of mini ovens is that they can be conveniently used to toast bread, as well as to cook small quantities of other small foods. Therefore, there is a growing trend of using them as a cooking device to replace existing toasters.

[0009] Typically, a mini oven includes an outer shell to house all the components, multiple shelves for placing food while cooking, and a cooking chamber with an opening on the front that allows food to be cooked by placing it inside.

[0010] In addition, the mini oven includes an oven heater for heating food to the appropriate temperature and a door for opening and closing the cooking chamber.

[0011] A door is provided to isolate and seal the interior of the cooking chamber from the outside while food is placed inside and cooked. Such a door may also include: a handle that allows easy opening and closing of the door; and a glass window that allows observation of the interior of the cooking chamber without opening the door.

[0012] In mini ovens, the door is mostly designed to be open at the bottom. That is, in the door of a mini oven, the lower end is rotatably connected to the outer shell via a door hinge, and the cooking chamber is opened by rotating the door downwards around the lower end rotatably connected to the outer shell. When the cooking chamber is open, the cooking chamber can be closed by rotating the door upwards.

[0013] The cooking chamber can be opened by rotating it approximately 90 degrees when the door is closed, and shelves can be inserted and extended while the cooking chamber is open.

[0014] That is, the door opens to be roughly parallel to the shelf inserted into the mini oven, and the user can directly insert and pull out the shelf.

[0015] However, the mini oven with the above structure has the following disadvantages.

[0016] First, when the door is opened, it inevitably protrudes forward of the mini oven by a distance equivalent to the height of the door. As a result, when the mini oven is installed in a confined space, it is difficult to accurately open the door and insert and extend the shelves.

[0017] Secondly, when the door is opened, as the door protrudes forward of the mini oven by a distance equivalent to the height of the door, the mini oven's center of gravity will tilt forward.

[0018] Mini ovens, which are relatively light in weight and size, inevitably tilt forward when the door is opened, increasing the risk of them tipping over.

[0019] In particular, when extending the shelf, it is often placed on top of the door to check the cooking status or to temporarily place the shelf. In this structure where the center of gravity of the mini oven is tilted forward, the risk of the mini oven tipping over will inevitably increase.

[0020] This risk is especially high when the shelf or the food placed on it is heavy. Therefore, it not only increases the danger of cooking heavier foods, but also creates a burden by adding weight to the shelf. In other words, even if a thick, heavy shelf is needed to improve cooking performance, it is difficult to use such a shelf due to the risk of the mini oven tipping over.

[0021] Third, the channels for inserting and extending the shelves, as well as the channels for checking the cooking status, are restricted to the front of the mini oven, resulting in various limitations.

[0022] In other words, the direction for inserting and extending the shelf is limited to the front-to-back direction, making it inconvenient to insert and extend the shelf when the mini oven is positioned low. Additionally, the only way to check the cooking status is through the glass window on the door, which is also very inconvenient when the mini oven is positioned low.

[0023] Typically, in order to accurately determine the overall cooking status of food, simply opening the door is not enough; the tray must be brought out.

[0024] In other words, when a user wants to accurately confirm the overall cooking status of the food, the user needs to directly open the door, pull out the shelf, and then insert the shelf. However, when the mini oven is installed in a low position, this operation is very inconvenient, and the possibility of injury, such as burns, increases during the process of pulling out and inserting the shelf.

[0025] Fourth, since the insertion and removal of the shelves are achieved by the user directly pulling the shelves out of the cooking chamber or pushing the shelves into the cooking chamber, this increases the inconvenience for the user and the risk of safety accidents.

[0026] In some situations, users may need to pull out the shelf during cooking to directly inspect the entire unit. In such cases, users will also need to grasp the shelf directly after opening the door and pull it out, and if cooking needs to continue, users will need to grasp the shelf directly and push it into the cooking chamber.

[0027] In other words, even just to check the cooking status, users need to open the door and directly extend or insert the shelf, which is inconvenient for users and poses a risk of injury, such as burns, to users during the process.

[0028] Especially during this process, because the mini oven's center of gravity is tilted forward, it may tip over, and in this case, the user's safety may be seriously threatened.

[0029] Existing document 1 (Japanese Patent No. 6289602) discloses a heating cooking machine that includes a cooking plate that moves in and out of the cooking chamber in conjunction with the opening and closing of a door.

[0030] According to the structure in existing document 1, a pair of sliding rails (hereinafter referred to as "first sliding rails") are provided in the cooking chamber, and a pair of sliding rails (hereinafter referred to as "second sliding rails") are also provided on the door, and the sliding rails are detachably connected to the sliding rails provided on the cooking chamber side.

[0031] The second slide rail is slidably coupled to the first slide rail, thereby allowing the door to be opened and closed by sliding in the front-back direction.

[0032] A support member is provided in a pair of second slide rails, and the cooking plate is placed on and supported from above at the upper end of the support member. That is, the cooking plate is supported by the support member on the second slide rail, which in turn is supported on the first slide rail.

[0033] With the above structure, the cooking plate can move in the front-back direction along with the door that moves in the front-back direction. That is, the cooking plate is linked to the action of the door that moves in the front-back direction and opens and closes the cooking chamber, so that it can move in the front-back direction and enter and exit the cooking chamber at the same time.

[0034] The advantage of the heating cooking machine in existing literature 1, which discloses this structure, is that by linking the entry and exit of the cooking plate with the opening and closing of the door, it is easier to insert and remove the cooking plate.

[0035] However, the heating cooking machine in the aforementioned existing document 1 still has the first and second disadvantages of the mini oven as described above.

[0036] That is, the heating cooking machine in the existing literature 1 also has the following disadvantages: when the door is opened, the door protrudes forward of the mini oven to a degree equivalent to the height of the door, and when the door is opened, the center of gravity of the mini oven tilts forward due to the door protruding forward of the mini oven to a degree equivalent to the height of the door.

[0037] In addition, since the heating cooking machine in the existing literature 1 only has a structure that links the entry and exit of the cooking plate with the opening and closing of the door, and the door still needs to be opened in this structure when it is necessary to confirm the cooking status, the inconvenience of the user having to open the door directly even when it is only necessary to confirm the cooking status has not been resolved.

[0038] Existing document 2 (Korean Utility Model Publication No. 20-2011-0001565) discloses a door opening and closing device for a toaster, wherein the structure of the device allows the front of the interior space of the toaster and a portion of the top of the interior space of the toaster to be opened together.

[0039] According to the construction in existing document 2, the door is located at the front of the toaster, and the door rotates towards the front of the toaster to open the interior space of the toaster. At this time, the door is configured to cover not only the front of the toaster, but also a portion of the top, so that when the door is opened, not only the front of the interior space of the toaster can be opened, but also a portion of the top of the interior space of the toaster can be opened at the same time.

[0040] Furthermore, according to the construction of existing document 2, the toaster bracket is located inside the door, and when the door is opened, the toaster bracket can rotate forward together with the door and can be extended to the outside of the cooking device.

[0041] The advantage of the toaster door opening and closing device in existing document 2, which discloses this structure, is that by linking the entry and exit of the toaster support with the opening and closing of the door, it is easier to insert and remove the toaster.

[0042] In addition, the advantage of the toaster door opening and closing device in the aforementioned existing document 2 is that, by opening the door, a portion of the top of the toaster's interior space is also opened, thus avoiding interference between the toaster and the frame of the cooking equipment housed in the toaster support when the door is opened and closed.

[0043] However, the device in existing document 2, which discloses this structure, has the first and second disadvantages of the mini oven mentioned above.

[0044] That is, the toaster in the existing literature 2 also has the following disadvantages: the door protrudes forward of the mini oven to the same degree as the height of the door when it is opened; the center of gravity of the mini oven tilts forward because the door protrudes forward of the same degree as the height of the door when it is opened; and various limitations exist because the insertion and exit channels of the shelf and the channel for confirming the cooking status are restricted to the front of the mini oven.

[0045] In addition, the device disclosed in the aforementioned prior art document 2 only has a structure that links the movement of the toaster bracket in and out with the opening and closing of the door. However, when it is necessary to confirm the cooking status, the door still needs to be opened in this structure. Therefore, the inconvenience of the user having to open the door directly even when it is only necessary to confirm the cooking status remains unresolved.

[0046] Furthermore, according to the device disclosed in the aforementioned existing document 2, since the toaster support is built inside the door, there is a problem that the center of gravity of the toaster tilts further forward when the door is opened.

[0047] That is, according to the structure disclosed in the existing document 2 above, when the door is opened, not only does the door open towards the front of the toaster, but the weight of the toaster support and the weight of the toaster housed in the toaster support are added to the weight of the door opening forward. This creates a problem that the center of gravity of the toaster tilts further forward when the door is opened, thereby further exacerbating the risk of the toaster tipping over.

[0048] Existing document 3 (U.S. Patent No. 6271502) discloses an oven with a front door and a top cover.

[0049] According to the structure in existing document 3, the front door is located at the front of the oven, and the top cover is located at the top of the oven. The front door and the top cover are located in different positions and operate independently. The front of the oven's interior space can be opened and closed by the front door, and the top of the oven's interior space can be opened and closed by the top cover.

[0050] However, the device in existing document 3, which discloses this structure, has the first and second disadvantages of the aforementioned mini oven.

[0051] That is, the oven in the existing literature 3 also has the following disadvantages: when the door is opened, the door protrudes forward of the mini oven to a degree equivalent to the height of the door, and when the door is opened, the center of gravity of the mini oven tilts forward due to the door protruding forward of the mini oven to a degree equivalent to the height of the door.

[0052] Furthermore, according to the structure disclosed in existing document 3, the interior space opened and closed by the front door and the interior space opened and closed by the top cover are separate spaces, rather than connected spaces.

[0053] That is, when the front door and the roof are opened together, the degree of openness of the interior space opened by the front door is not expanded; opening the roof only opens the interior space that can be opened by the roof.

[0054] Existing document 4 (U.S. Patent No. 6,029,649) discloses a structure for opening and closing an oven door in a cylindrical oven.

[0055] According to the door in existing document 4, a door is provided on a cylindrical body, and the door can rotate along the periphery of the cylindrical body to open and close the body. When such a door is opened, it does not protrude to the front or back of the body, but can only rotate along the periphery of the body to open and close the body.

[0056] However, the device in existing document 4, which discloses this structure, has the following drawbacks.

[0057] First, the door disclosed in existing literature 4 can only be applied to the main body of the cooking equipment in a cylindrical shape, and cannot be applied to the main body of the commonly used hexahedral cooking equipment, thus having the disadvantage of low compatibility.

[0058] Secondly, it is difficult to install structures such as shelves for placing food inside the main body disclosed in existing literature 4. In addition, even if structures such as shelves are installed inside the main body, there are many difficulties in leading out and inserting such shelves due to the structure of the main body.

[0059] Furthermore, based on the door structure disclosed in existing document 4, it is difficult to position the operating switch on the front or top surface of the cooking appliance. This is because the front and top surfaces of the main body are mostly covered by the door or located within the door's rotation range. Therefore, existing document 4 discloses a configuration in which an operating switch, such as a timer, is positioned on the side of the main body.

[0060] However, as mentioned above, if the operating switch is located on the side of the cooking appliance rather than on the front or top, it will be inconvenient for the user to check the status of the operating switch or to operate it. Therefore, from the perspective of user convenience, it is difficult to consider the operating switch configuration in existing document 4 as the preferred form.

[0061] Furthermore, none of the existing documents 1 to 4 discloses a form in which the operating switch is located within the door. In existing documents 1 to 4, the operating switch is located within the main body.

[0062] In particular, existing documents 1 and 3 disclose a structure in which the operating switch is disposed on the main body of the cooking appliance and on the outer side of the door in the left and right directions. However, in this structure, the left and right width of the main body needs to be increased by an amount corresponding to the space required to place the operating switch. Therefore, there is a problem that although the overall size of the cooking appliance increases, the width of the door opening becomes relatively narrower.

[0063] Furthermore, existing document 2 discloses a structure in which the operation switch is located at the lower part of the main body of the cooking device. However, in this structure, as the position of the operation switch becomes lower, it is inconvenient for the user to operate the operation switch. In addition, according to the structure disclosed in existing document 2, the vertical length of the main body needs to be increased by an amount corresponding to the space required for arranging the operation switch. Therefore, although the overall size of the cooking device increases, the width of the door opening becomes relatively narrower.

[0064] Finally, in existing document 4, when the switch is configured on the side of the cooking device as described above, it is inconvenient for the user to check the status of the operation switch, or it is inconvenient to operate the operation switch.

[0065] In the constructions disclosed in existing documents 1 to 4, it is difficult to place the operating switch within the door. According to the constructions disclosed in existing documents 1 to 4, a viewing window is placed within the door to ensure the user can observe the interior of the cooking room; however, since such a viewing window occupies most of the door area, it is difficult to ensure sufficient space within the door for installing the operating switch.

[0066] In addition, if the operation switch is placed on the door, the control board that is electrically connected to the operation switch also needs to be placed inside the door, but it is also difficult to ensure space inside the door for such a control board.

[0067] Therefore, in order to provide a structure in which the operating switch is configured on the door, it is necessary to design a structure that solves the problems described above.

[0068] Furthermore, none of the aforementioned existing documents disclose any structure for preventing the leakage of hot air and water vapor inside the cooking chamber through the gap between the main body and the door of the cooking equipment.

[0069] In existing literature, especially in existing literature 2 and existing literature 3, a structure is disclosed in which a portion of the front and top of the interior space of the toaster or main body also opens when the door is opened. As mentioned above, the wider the range of the door opening, the greater the risk of hot air and water vapor inside the cooking chamber leaking through the gap between the main body of the cooking appliance and the door.

[0070] If hot air and steam inside the cooking chamber leak out through the gap between the main body and the door of the cooking appliance toward the front of the appliance, the risk of injury to the user from the leaked hot air or steam increases.

[0071] Additionally, issues may arise such as water vapor leaking through the gap between the cooking appliance body and the door, causing condensation on and around the door, or condensation on the door leading to water accumulation around the door.

[0087] Technical solutions to the problem

[0088] In a cooking apparatus according to one embodiment of the present invention for achieving the above-mentioned objective, the front and top of the housing are opened together when the door is opened.

[0089] In another embodiment of the invention, the invention is characterized by including a hinge assembly that rotatably supports the door, and having cooling flow paths inside the hinge assembly for cooling the front and top surfaces of the cooking equipment.

[0090] The cooling flow path can be biased towards the front and top of the hinge assembly.

[0091] Additionally, a cooling fan may be provided at the lower part of the cooling flow path.

[0092] This allows for the cooling of parts that are prone to overheating due to heat and are frequently in contact with the user. This prevents safety accidents and protects internal door components from damage due to overheating.

[0093] In addition, another aspect of the invention is characterized by including an exhaust guide disposed on the side of the housing, which generates airflow in front of the cooking chamber and generates at least one of airflow from one side of the housing to the other side and airflow from the front of the cooking chamber to the rear side of the housing.

[0094] The exhaust guide may include a cooling flow path formed inside the hinge assembly.

[0095] Preferably, a cold air outlet is provided on the side of the housing, through which external air flowing into the cooling flow path can be discharged into the cooking chamber.

[0096] This structure effectively prevents the hot air and water vapor generated inside the cooking chamber from leaking out of the cooking equipment from the front side.

[0097] Another aspect of the present invention is characterized in that a control board is disposed inside the door, and a cooling fan is disposed in the same space where the control board is disposed, the cooling fan exhausting the air in the space where the control board is disposed to the outside of the door.

[0098] This structure can reduce the effects of hot air or water vapor on the various components configured on the door.

[0099] In addition, the cooling fan can be positioned closer to the cooling vents than the top of the door.

[0100] Preferably, the cooling fan can be configured below the touch panel support and the temperature sensor, which are located at a position lower than the top of the door.

[0101] This structure can suppress the re-intake of high-temperature air and water vapor expelled from the cooling fan, as well as the inflow of water vapor from the inside of the top surface of the door into the inside of the front surface of the door, thereby improving the cooling efficiency and water vapor removal efficiency of the door interior.

[0102] In addition, another aspect of the present invention is characterized in that a cable mounting part is provided inside the top part of the door, and a cable connecting the first control board and the first heating part is provided.

[0103] With this structure, users can look down into the cooking chamber through a viewing window formed at the top of the cooking equipment, thus providing users with an easy and convenient way to check the cooking status of the food without having to lower their posture or bend over.

[0104] In another aspect of the present invention, the support panel is combined with and fixed inside the door body and at least one of the door body and the door back cover, and the control board is fixed to the support panel.

[0105] Another aspect of the invention is characterized in that the handle, support panel, and door are combined together on a single bracket.

[0106] In another aspect of the invention, the back cover, control board, support panel, and door are combined together on a single bracket.

[0107] As a result, the various components that make up the interior of the door can be stably fixed inside the door, which can reduce the time required for door assembly and make the door assembly process easier and faster.

[0108] Another aspect of the invention is characterized in that a temperature sensor is disposed on the door of the cooking chamber, protruding outward toward the door from the cooking chamber.

[0109] Another aspect of the invention is characterized in that a temperature sensor is disposed on the door of the cooking chamber, the temperature sensor protruding outward toward the door and being biased toward the upper part of the cooking chamber.

[0110] Here, the temperature sensor is positioned between the tray and the heating element, and can be configured to be closer to the heating element.

[0111] In addition, the temperature sensor can be positioned near the upper corner of the front of the door.

[0112] In addition, the temperature sensor can be configured in a position where the heating element is blocked by a shielding plate.

[0113] Another aspect of the invention is characterized in that a viewing window is disposed on the top surface of the door.

[0114] Therefore, even if the cooking equipment is set in a low position, users can easily and conveniently check the cooking status of the food without having to lower their posture or bend over.

[0115] In addition, another aspect of the present invention is characterized in that the first heating element is disposed on the top surface of the door.

[0116] The first heating element, which is arranged on the upper part of the tray, can be provided on the top part of the door covering the housing. Thus, the first heating element can be arranged in a position separated from the operating device and the first control board, and the center of gravity of the door can be biased to the rear side.

[0117] In another aspect of the present invention, the first heating element and the viewing window are disposed on the top surface of the door, and the operating device is disposed on the front surface of the door where the first heating element and the viewing window are not provided.

[0118] Another aspect of the invention is characterized in that relatively heavy components, such as glass and heaters, are arranged on the top surface of the door so that when the front and top surfaces of the door are opened, the center of gravity of the cooking appliance is shifted from the front-to-back direction to the rear.

[0119] The cooking equipment configured as described above reduces the risk of tipping over when the door is opened by shifting the center of gravity of the cooking equipment from the front-to-back direction to the rear.

[0161] Invention Effects

[0162] The invention is designed so that the front and top of the cooking chamber can be opened by rotating the door upwards, without opening the door forwards. Thus, even in narrow spaces, the door can be opened easily and smoothly, and food or trays can be brought out more easily and conveniently.

[0163] In addition, the present invention can open the front and top of the door, so that more of the tray is exposed when the door is opened. Therefore, even if only part of the tray is brought out, the food can be easily put in or taken out, thereby further improving convenience and stability.

[0164] Furthermore, according to the present invention, the door is configured to open and close by rotating upwards rather than unfolding forwards. Therefore, even when the door is opened, the center of gravity of the cooking appliance is less likely to tilt forward, thus significantly reducing the risk of the cooking appliance tipping over.

[0165] Furthermore, according to the present invention, the rotation center of the door is formed on the rear side of the cooking appliance, and the center of gravity of the door is formed to be more biased towards the top of the door than the front side of the door. When the door is opened, the center of gravity of the cooking appliance is biased towards the rear side of the cooking appliance. Therefore, the risk of the cooking appliance tipping over is significantly reduced, thereby improving the safety and ease of use of the cooking appliance.

[0166] In addition, the present invention allows the operating device to be mounted on the door, thereby reducing the size of the housing and providing a sufficiently large entrance and exit for trays and food to enter and exit, thus achieving a compact appearance and providing further improved ease of use.

[0167] In addition, the present invention adopts a structure in which the viewing window is located at the top of the door and the operating device is located in front of the door. Therefore, the effect is that even if the cooking equipment is set in a low position, the user can easily and conveniently check the cooking status of the food without having to lower their posture or bend over, and the user can face the cooking equipment from the front and easily and conveniently operate the operating switch.

[0168] Furthermore, according to the present invention, the various components constituting the interior of the door can be stably fixed inside the door, and the time required for door assembly can be reduced, making door assembly easier and faster.

[0169] In addition, the present invention can prevent safety accidents and damage to internal door components caused by overheating by cooling parts that are prone to temperature rise under heat and are likely to come into contact with users.

[0170] Furthermore, the present invention adjusts the distance between the front and front parts of the housing or the distance between the front end of the side of the housing and the front part of the door, or the distance between the front end of the side of the housing and the front part of the door, based on the front-rear position of the fastening part that is coupled with the position adjustment guide, thereby enabling effective tolerance management related to the Y-axis clearance.

[0171] This invention not only prevents the door from failing to open and close properly due to inadequate tolerance management related to the door's Y-axis clearance, but also effectively suppresses the leakage of hot air or steam inside the cooking chamber.

[0172] In addition, the present invention can use a fastening bracket to make the front of the cabinet fit tightly against the front of the shell, thereby not only making the tolerance management related to the gap between the shell and the cabinet easier, but also improving the appearance quality of the cooking equipment while reducing the difficulty of cabinet installation.

[0173] In addition, by attaching the front of the housing to the front of the shell in a close-fitting manner, the present invention can prevent air leakage through the gap between the front of the housing and the front of the shell, and can effectively expel cold air through the cold air discharge section.

[0174] In addition, by placing the sealing gasket at the contact point between the door and the housing when the cooking chamber is closed, the present invention can effectively prevent scratches on the door or housing caused by contact between the door and the housing during the opening and closing of the cooking chamber.

[0175] In addition, by using a sealing gasket to absorb the impact applied to the door when the cooking chamber is closed, the present invention can effectively prevent damage to the door itself or the components installed on the door that may occur during the opening and closing of the cooking chamber.

[0176] In addition, the present invention can effectively suppress the heat and steam generated inside the cooking chamber during cooking from escaping to the front side of the door.

[0177] This invention effectively prevents users from being injured by hot air or steam leaking into the front of the cooking appliance through the gap between the door and the housing.

[0178] In addition, by preventing water vapor from leaking through the gap between the door and the housing onto the door and condensing, or by preventing the dew on the door from forming water accumulation around the door, the present invention can effectively prevent the cooking equipment and its surroundings from being contaminated by water vapor.

[0179] Furthermore, by allowing hot air or water vapor flowing into the front of the door, which contains the control board and operating device, to be smoothly discharged to the outside of the door, the present invention can reduce the performance degradation and risk of malfunction of the components inside the door.

[0180] In addition, the present invention is characterized by suppressing the re-inhalation of high-temperature air and water vapor emitted from the cooling fan and the inflow of water vapor from the interior of the top surface of the door into the interior of the front surface of the door by appropriately setting the position of the first cooling fan inside the door.

[0181] This invention, by improving the cooling efficiency and water vapor removal efficiency inside the door, can further and effectively reduce the performance degradation and risk of malfunction of the components inside the door. Attached Figure Description

[0300] Furthermore, a second heating element 600 may be provided on the lower part of the bottom surface of the housing 100, and an electrical component associated with the operation of the second heating element 600 may be provided on the rear side of the back of the housing 100, such as the second control board 700 described later.

[0301] In addition, hinge assemblies 800 can be provided on the outer sides of the two sides 120 and 130 of the housing 100, and the door 300 can be rotatably mounted on the housing 100 by means of the engagement with the hinge assemblies 800 provided as described above.

[0302] As an example, the housing 100 can be manufactured by bending a metal plate into a “└┘” shape, and the bent metal plate forms the bottom surface and two side surfaces of the housing 100 as described above. When the housing 100 is manufactured in the manner described above, the bottom surface 110 of the housing 100 can be integrally connected with the two side surfaces 120, 130 without forming a seam.

[0303] This not only improves the aesthetics of the interior of the cooking chamber 105, but also prevents foreign objects from getting stuck in the gap between the bottom surface 110 and the two sides 120, 130 of the housing 100, or prevents the second heating unit 600 from being contaminated by foreign objects leaking out through the gap.

[0304] As another example, the casing 100 can also be manufactured such that, respectively, The left and right protruding portions of the shaped metal plate are bent upwards to form the bottom surface 110 and two side surfaces 120 and 130 of the shell 100, respectively, and the rear protruding portion is bent upwards to form the back surface 140 of the shell 100. When the shell is manufactured in the above manner, the bottom surface 110, the two side surfaces 120 and 130, and the back surface 140 of the shell 100 can be integrally formed without any seams between the bottom surface 110 and the two side surfaces 120 and 130, or between the bottom surface 110 and the back surface 140.

[0305] Therefore, when viewed from the front and top, the seams inside the cooking chamber 105 are almost invisible, and the inner surface of the cooking chamber 105 can maintain a smooth plane. Thus, not only can the aesthetics of the interior of the cooking chamber 105 be further improved, but also stains stuck to the inner surface of the cooking chamber 105 can be easily removed.

[0306] Additionally, the bottom surface 110 of the housing 100 may include ceramic glass, which may be formed of a rectangular flat plate shape with a specified thickness.

[0307] As an example, ceramic glass can be disposed in the cut-out central portion of the bottom surface 110 made of metal material, and such ceramic glass can be disposed between the second heating part 600 and the tray 200.

[0308] Additionally, a rear shell 150 is disposed on the rear side of the back surface 140 of the housing 100, the rear shell 150 being used to accommodate the second control board 700, which will be described later. The second control board 700 is accommodated in the rear shell 150 and disposed on the rear side of the housing 100, and an insulating plate 160 is disposed between the back surface 140 and the rear shell 150 of the housing 100.

[0309] The insulating plate 160 isolates the heat inside the cooking chamber 105 from being transferred to the second control board 700 side through the back side 140 of the housing 100, and also serves to insulate the rear shell 150 on which the second control board 700 is disposed from the housing 100.

[0310] Additionally, the housing 100 of this embodiment may also include a box 170. The box 170 is configured to cover the two sides 120, 130 and the back 140 of the housing 100. Such a box 170 surrounds and protects the hinge assembly 800 disposed on the two sides 120, 130 of the housing 100 and the second control base plate 700 disposed on the back 140 of the housing 100 from the outside, and forms the appearance of the side and rear sides of the cooking device.

[0311] [Door Structure]

[0312] Figure 5 This is a perspective view showing the gates of an embodiment of the present invention separated. Figure 6 It is shown Figure 5 The image shows a bottom-view perspective of the door. Additionally, Figure 7 It is Figure 6 The structure of the door shown is disassembled and illustrated in an exploded perspective view. Figure 8 It is shown Figure 1 The side sectional view of the internal structure of the cooking equipment shown is shown. Figure 9 It is shown in magnification Figure 8 An enlarged view of the "IX" section. Additionally, Figure 10 It is along Figure 1 A sectional view taken along the "XX" line. Figure 11 It is shown in magnification Figure 10 An enlarged view of the "XI" part.

[0313] Reference Figures 5 to 11 The door 300 is formed by a top surface portion 310 constituting the top surface of the door 300 and a front surface portion 350 constituting the front surface of the door 300. The shapes are connected in a unified form.

[0314] The top surface 310 of the door is formed into a quadrilateral, and can be formed into a rectangle in which the length in the left-right direction is greater than the length in the front-back direction. A door frame 320 can be provided on the top surface 310. The door frame 320 is provided at the lower part of the top surface 310, and the first heating part 400 can be provided at the lower part of the top surface 310 in a manner combined with the door frame 320.

[0315] Door 300 may include a viewing window W. The viewing window W is disposed on the top surface 310 of the door and may be located in the central portion of the top surface 310 in the planar direction.

[0316] Such a viewing window W may include a pair of glass panes 330 and 335, which are spaced apart vertically by a predetermined interval to form a space inside the viewing window W. As an example, one of the glass panes 330 (hereinafter referred to as the "first glass") may be disposed on the top surface 310 of the door, while the other glass pane 335 (hereinafter referred to as the "second glass") may be disposed on the door frame 320.

[0317] Through holes can be formed in the top surface 310 of the door and the door frame 320, respectively. The through holes can be formed in the center of the top surface 310 in the planar direction and the center of the door frame 320 in the planar direction, respectively.

[0318] According to this embodiment, a first glass 330 covers the through hole formed in the top surface 310 of the door from the top and is disposed in the top surface 310 of the door, and a second glass 335 covers the through hole formed in the door frame 320 from the top and is disposed in the door frame 320.

[0319] The first glass 330 and the second glass 335 can be made of transparent or translucent glass, and the viewing window W can be formed in the through-hole portion covered by the first glass 330 and the second glass 335.

[0320] The user can view the interior of the cooking chamber 105 from above through the viewing window W formed as described above, thereby confirming the cooking status of the food inside the cooking chamber 105. Given the characteristics of a mini oven, the cooking device of this embodiment is likely to be used frequently at a position significantly below the user's face. Therefore, the viewing window W formed on the top surface of the door 300 provides a means for the user to easily and conveniently confirm the cooking status of the food without having to lower their posture or bend over.

[0321] Furthermore, the pair of glass panes 330 and 335 forming the viewing window W are respectively attached to different components, namely, one is attached to the top surface 310 and the other is attached to the door frame 320, and they are separated by a predetermined interval. Therefore, a space between the two glass panes 330 and 335 is formed inside the viewing window W.

[0322] For example, a first glass 330 is disposed at the top of the top surface 310 of the door, while a second glass 335 is disposed in the door frame 320, thereby the first glass 330 and the second glass 335 can be separated by an amount corresponding to the thickness of the top surface 310 of the door.

[0323] That is, between the first glass 330 and the second glass 335 forming the viewing window W, at least a gap space corresponding to the thickness of the top surface 310 of the door is formed, thereby creating a gap space between the two glass panes 330 and 335 inside the viewing window W. Furthermore, air can flow into the gap space formed as described above, and the air flowing into the gap space as described above can form an air layer within the gap space.

[0324] An air layer formed in the spacer formed in the manner described above is used to block the transfer of heat from the second glass 335, which is directly exposed to the cooking chamber 105, to the outermost first glass 330.

[0325] Therefore, as described above, the viewing window W with a double-layered structure has the function of effectively preventing safety accidents caused by overheating of the viewing window W and fogging caused by the temperature rise of the viewing window W.

[0326] Furthermore, the through hole formed on the top surface 310 of the door can be formed to have a narrower width than the through hole formed on the door frame 320. Additionally, the through hole formed on the top surface 310 of the door can be formed to be located inside the through hole formed on the door frame 320 when viewed from above.

[0327] That is, the through hole formed on the top surface 310 of the door can be configured such that, when viewed from above, the inner edge of the door frame 320 is not exposed through the viewing window W. In this case, since the door frame 320 is not exposed through the viewing window W, it has an aesthetic advantage.

[0328] On the other hand, the first heating element 400 is disposed on the top surface of the door 310 and positioned in an area that is not exposed through the viewing window W when viewed from above. This first heating element 400 is respectively disposed on the front outer side and the rear outer side of the viewing window W on the transverse plane formed by the top surface of the door 310. In other words, the first heating element 400 can be disposed on the outer side of the through hole formed in the top surface of the door 310 and the door frame 320, respectively. That is, the cooking device of this embodiment may include a pair of first heating elements 400 respectively disposed on the front outer side and the rear outer side of the viewing window W.

[0329] If the first heating element 400 is positioned in the area exposed through the viewing window W, it will not only be unsightly, but it may also cause problems in ensuring the field of vision through the viewing window W, and may also cause the temperature of the viewing window W portion to rise.

[0330] Furthermore, given that the shape of the front face 350 is a rectangle with a length greater than its length in the front-back direction, the first heating element 400 is positioned on the front outer side and the rear outer side of the viewing window W so that the length of the first heating element 400 can be increased accordingly. As the length of the first heating element 400 increases, the heat output of the first heating element 400 can be expected to increase.

[0331] Taking these aspects into consideration, the first heating element 400 is respectively disposed on the front outer side and the rear outer side of the viewing window W, thereby helping to ensure functional advantages such as maintaining aesthetics, ensuring a clear field of vision, suppressing the temperature rise of the viewing window W, and improving the firepower of the first heating element 400.

[0332] Similar to the top surface 310, the front surface 350 can be rectangular. However, if the top surface 310 forms a plane in the horizontal direction, then the front surface 350 forms a plane in the vertical direction.

[0333] As an example, the front face 350 can be formed to extend downward from the front end of the top face 310. Furthermore, the connection between the front face 350 and the top face 310 can be achieved by connecting their internal spaces. That is, the door 300 can be provided such that the front face 350 and the top face 310, whose internal spaces are connected, are integrally connected. The shape or form of a shape.

[0334] The operating device 1000 and the first control board 500 can be disposed on the front face portion 350 of the door. In this embodiment, an example is shown where a space is formed inside the front face portion 350 of the door. At least a portion of the operating device 1000 and the first control board 500 can be accommodated in such a space.

[0335] The operating device 1000 may include various operating switches for controlling the motion of the cooking equipment of this embodiment. Such an operating device 1000 may be configured to be exposed to the front of the door front face 350, so that the user can directly operate such an operating device 1000 to adjust the motion of the cooking equipment.

[0336] The first control board 500 is disposed inside the front face portion 350 of the door. The first control board 500 is provided with various components and circuits related to receiving operation signals input through the operation device 1000 and generating control signals for controlling the operation of the first heating unit 400 and the second heating unit 600.

[0337] The first control board 500 needs to be electrically connected to the operating device 1000, the first heating unit 400, and the second heating unit 600. Similar to the operating device 1000, such a first control board 500 is disposed on the front face 350 of the door, and is disposed very close to the operating device 1000, and also very close to the first heating unit 400 disposed on the same door 300.

[0338] According to this embodiment, the operating device 1000 can be electrically connected to the first control board 500 by being directly mounted on it. In this case, each operating switch provided on the operating device 1000 can pass through the front panel 350 of the door and be connected to the first control board 500. Furthermore, the first heating unit 400 can be electrically connected to the first control board 500 via a cable that passes through the interior of the front panel 350 and the top panel 310 of the door, which are connected to each other.

[0339] That is, the first control board 500, the operating device 1000 and the first heating unit 400, which need to be electrically connected to each other, are arranged in a very close and spatially connected position. Therefore, it is easy and quick to perform the operation to establish the electrical connection between them, and the connection structure between them can also be kept in a very stable state.

[0340] Additionally, the cooking apparatus of this embodiment may also include cable mounting portions 340 and 345. The cable mounting portions 340 and 345 are disposed between the door top surface 310 and the door frame 320 arranged in the vertical direction, and are respectively disposed on the outer sides of the viewing window W.

[0341] In addition, connecting members 343 are respectively disposed on the front outer side and the rear outer side of the viewing window W. Such a pair of connecting members 343 connects a pair of cable mounting portions 340, 345 that are spaced apart from each other. That is, the pair of cable mounting portions 340, 345 and the connecting members 343 are arranged in an "opening" shape surrounding the viewing window W on the outside.

[0342] The cable mounting portions 340 and 345 and the connecting member 343, which are provided in the manner described above, are provided on the top surface 310 of the door in the form of being inserted into the space formed between the top surface 310 of the door and the door frame 320.

[0343] As described above, the interior of the top part 310 of the door, which is provided with cable mounting portions 340 and 345, is connected to the interior of the front part 350 of the door. Furthermore, cables C1 and C2 are provided in the cable mounting portions 340 and 345 of the top part 310 of the door, and the cables C1 and C2 pass through the interior of the top part 310 and the interior of the front part 350 of the door, which are connected to each other, so that the first control board 500 and the first heating part 400 are connected to each other.

[0344] A power cable C2 for supplying power to the first heating unit 400 and the first control board 500 may be provided in either of the cable mounting portions 340 and 345 respectively located on the outer sides of both sides of the viewing window W. Furthermore, a signal cable C1 for transmitting control signals generated by the first control board 500 to the first heating unit 400 may be provided in the other of the cable mounting portions 340 and 345 respectively located on the outer sides of both sides of the viewing window W.

[0345] That is, in the door 300, the first heating unit 400 is arranged on both sides in the front-to-back direction with the viewing window W as the center, and the power cable C2 and the signal cable C1 are arranged on the left and right sides with the viewing window W as the center.

[0346] The configuration of the first heating element 400, the power cable C2, and the signal cable C1 is the result of a design that takes into account the configuration of the first heating element 400 and the hinge assembly 800.

[0347] According to this embodiment, each first heating element 400 is arranged such that its heating element extends relatively long in the left-right direction. Furthermore, the hinge assembly 800 (see...) Figure 3 The perspective window W is positioned on both sides in the left and right directions.

[0348] Power cable C2 and signal cable C1 are connected not only to components disposed in door 300, such as first heating unit 400 and first control board 500, but also to components disposed in housing 100, such as second control board 700 (see reference). Figure 38 ).

[0349] If such power cable C2 and signal cable C1 are to pass between door 300 and housing 100 in a manner that is as unexposed as possible, it is most preferably through the portion of hinge assembly 800 which is configured as the only connection between door 300 and housing 100.

[0350] As an example, the connection section between the housing 100 and the door 300 in the power cable C2 and signal cable C1 can be configured to pass through the interior of the hinge assembly 800. This prevents the power cable C2 and signal cable C1 from being exposed to the outside of the cooking appliance in the section between the housing 100 and the door 300, and avoids damage to the power cable C2 and signal cable C1.

[0351] Furthermore, considering that the heating element of the first heating section 400 is configured to extend relatively long in the left-right direction, preferably, the power cable C2 and the signal cable C1 are configured as far away from the heating element as possible, and are configured to extend in a direction different from the extension direction of the heating element.

[0352] This is a design feature intended to prevent the heat generated in the first heating element 400 from affecting the power cable C2 and the signal cable C1. Furthermore, considering that the plurality of first heating elements 400 are spaced apart in the front-to-back direction, the structure in which the power cable C2 and the signal cable C1 are positioned on either side of the first heating element 400 in the left-to-right direction facilitates the connection of these first heating elements 400 to the power cable C2 and the signal cable C1.

[0353] In addition, in this embodiment, the power cable C2 and the signal cable C1 can be arranged separately from each other in the left and right directions through the viewing window W, and can be set in different cable mounting parts 340, 345.

[0354] At this time, the power cable C2 can pass through the interior of either of the hinge assemblies 800 respectively disposed on the two sides of the housing 100, and be disposed in the cable mounting portions 340 and 345 adjacent to the hinge assembly 800. The signal cable C1 can pass through the interior of the other hinge assembly 800 respectively disposed on the two sides, and be disposed in the cable mounting portions 340 and 345 adjacent to the hinge assembly 800.

[0355] For example, the power cable can pass through the interior of the hinge assembly 800 located on the left side of the housing 100 and be installed in the cable mounting portions 340 and 345 on the left side of the door 300, and the signal cable C1 can pass through the interior of the hinge assembly 800 located on the right side of the housing 100 and be installed in the cable mounting portions 340 and 345 on the right side of the door 300.

[0356] As mentioned above, wiring for establishing electrical connections between the various components that make up the cooking equipment can be performed more simply and quickly by configuring cables with different functions in different locations, and related maintenance work can also be performed more easily.

[0357] On the other hand, the cable mounting portions 340, 345 and the connecting member 343 can be disposed between the first glass 330 and the second glass 335, which are spaced apart in the vertical direction. That is, the cable mounting portions 340, 345 and the connecting member 343 can be placed on top of the second glass 335, and the first glass 330 can be placed on top of the cable mounting portions 340, 345 and the connecting member 343.

[0358] Mounting grooves may be provided on the top surfaces of the cable mounting portions 340 and 345 that contact the first glass 330 and the bottom surfaces of the cable mounting portions 340 and 345 that contact the second glass 335.

[0359] In addition, mounting grooves may be provided on the top surface of the connecting member 343 that contacts the first glass 330 and the top surface of the connecting member 343 that contacts the second glass 335, respectively.

[0360] Sealing members S can be provided in each mounting slot. That is, sealing members S can be provided between the cable mounting parts 340, 345 and the first glass 330, between the cable mounting parts 340, 345 and the second glass 335, between the connecting member 343 and the first glass 330, and between the connecting member 343 and the second glass 335.

[0361] Therefore, a sealed structure utilizing the sealing member S can be formed between the cable mounting parts 340, 345 and the connecting member 343 and the first glass 330, and between the cable mounting parts 340, 345 and the connecting member 343 and the second glass 335.

[0362] The airtight structure formed in this way helps prevent moisture from entering between the glass panes 330 and 335, thereby helping to prevent moisture or condensation from forming in the glass panes 330 and 335.

[0363] [Structure of the operating device]

[0364] Reference Figure 5 The operating device 1000 may include various operating switches for operating the motion control of the cooking equipment of this embodiment.

[0365] Such an operating device 1000 can be configured to be exposed to the front of the door 350, allowing the user to directly operate such an operating device 1000 to adjust the operation of the cooking equipment.

[0366] As an example, the operating device 1000 may include an operating switch for selecting the type or state of the object being cooked, an operating switch for selecting the degree of cooking or the cooking time, etc.

[0367] As another example, the operating device 1000 may also include a means for turning the first heating unit 400 on / off (see reference). Figure 2 (or an operating switch for adjusting the heat of the first heating unit 400, used to turn the second heating unit 600 on / off (see reference)) Figure 3 (or an operating switch for adjusting the heat of the second heating unit 600, a timer operating switch for adjusting the operating time of the first heating unit 400 or the second heating unit 600, etc.)

[0368] In this embodiment, the operating device 1000 is illustrated by including two operating switches. One switch can be configured to select the type or state of the object being cooked, and the other switch can be configured to select the cooking degree or cooking time.

[0369] At least one of the operating switches may be provided in a form that allows for both rotational and pressing operations. In this embodiment, the operating switches are provided as examples of being capable of both rotational and pressing operations.

[0370] Furthermore, in this embodiment, the operating device 1000 is illustrated by including operating switches having the same or similar configurations. In this case, each operating switch can be provided to achieve different functions using the same or similar configurations.

[0371] For example, both operating switches are provided in a form that allows for rotation and pressing operations, one of which can be configured to select the type and state of the object being cooked, while the other can be configured to select the degree of cooking or the cooking time.

[0372] The configuration of the operating device 1000 will be described below using one of the two operating switches as an example.

[0373] Figure 12 It is shown Figure 5 A 3D view showing a portion of the door removed. Figure 13 It is along Figure 12 A sectional view taken along line "XIII-XIII". Figure 14 It is Figure 13 The exploded perspective view of the structure of the operating device shown is presented.

[0374] Reference Figures 12 to 14 The operating device 1000 includes an operating switch, which may include a shaft 1100 and a knob 1300.

[0375] A shaft 1100 is provided in an encoder 1200, which is also provided in an operating device 1000. This shaft 1100 can be provided as a shaft extending in the front-rear direction. Alternatively, the shaft 1100 can be configured to rotate around an axis in the front-rear direction.

[0376] The encoder 1200 can be configured to detect the rotation angle of such a shaft 1100. In this embodiment, the encoder 1200 is shown as being installed on the first control board 500. Such an encoder 1200 can be installed on the first control board 500 and can be configured inside the front face 350 of the door.

[0377] Additionally, the encoder 1200 can be electrically connected to the first control board 500. This encoder 1200 can detect the rotational angle or axial movement of the shaft 1100 and transmit a corresponding signal to the first control board 500. The first control board 500 can generate a signal for controlling the first heating unit 400 (see reference 1200) based on the signal received from the encoder 1200. Figure 2 ), second heating section 600 (refer to) Figure 3 ) and the control signal for the operation of the light-emitting component 1700, which will be described later.

[0378] The knob 1300 is a component that allows the user to perform rotational operations. The knob 1300 can be connected to the shaft 1100 by engaging with it. Such a knob 1300 can be connected to the shaft 1100 to rotate and move axially together with the shaft 1100.

[0379] The knob 1300 may include a shaft engagement portion 1310. The shaft engagement portion 1310 may be formed into a flat cylindrical shape. A shaft engagement hole 1311 may be formed inside the shaft engagement portion 1310. The shaft engagement hole 1311 may be formed to be recessed into the shaft engagement portion 1310 and formed into a shape corresponding to the shape of the shaft 1100.

[0380] Such a shaft engagement hole 1311 can be opened towards the rear of the shaft engagement portion 1310. In addition, the front of the shaft engagement hole 1311 can be closed by the front of the shaft engagement portion 1310. Through such a shape of the shaft engagement portion 1310, the setting position and insertion depth of the shaft 1100 engaged with the shaft engagement portion 1310 can be guided.

[0381] On the other hand, the operating device 1000 of this embodiment may also include a socket member 1600. The socket member 1600 is provided to support the knob 1300 in a rotatable or axially movable manner on the door 300. The socket member 1600 may be provided on the door 300, and more specifically, may be provided inside the front face 350 of the door.

[0382] Such a socket member 1600 can be provided inside the front face portion 350 of the door so as to accommodate the encoder 1200 installed inside the front face portion 350 from the outside in the diametrical direction. Furthermore, the shaft 1100 connected to the encoder 1200 can protrude forward of the socket member 1600 through approximately the center in the diametrical direction.

[0383] The socket member 1600 can serve the following functions: protecting the encoder 1200 by accommodating it internally; supporting the knob 1300, which is coupled to the shaft 1100, from the outside in the diametrical direction; supporting the knob 1300 from the rear; and limiting the path of light emitted from the light-emitting member 1700, which will be described later.

[0384] In addition, the operating device 1000 of this embodiment may also include a light-emitting component 1700. The light-emitting component 1700 is disposed on the first control substrate 500 and can be lit up to emit light through the action control implemented by the first control substrate 500.

[0385] The light-emitting member 1700 can be disposed behind the socket member 1600. Furthermore, a channel can be formed in the socket member 1600 to allow light emitted from the light-emitting member 1700 to pass to the front of the socket member 1600.

[0386] The path of the light emitted from the light-emitting member 1700 is defined by the socket member 1600. This light can be used to indicate information such as the operating state of the operating device 1000 and the state of motion control performed according to the operation of the operating device 1000.

[0387] Additionally, the operating device 1000 of this embodiment may also include light-emitting components 1700 for ambient lighting. Each light-emitting component 1700 for ambient lighting is disposed on the first control substrate 500 and may be positioned behind the socket component 1600. Such light-emitting components 1700 for ambient lighting may be positioned inside the light-emitting component 1700 in the diametrical direction.

[0388] Light emitted from each of the light-emitting components 1700 can pass through the socket component 1600 through channels formed in it and illuminate the rear of the knob 1300. These channels can be formed to extend through the first connecting support portion 1630. More specifically, the channels are arranged radially and can be holes formed between a plurality of ribs 1633 arranged at predetermined intervals.

[0389] The ambient lighting provided by the light-emitting component 1700 described above can provide indirect lighting to illuminate the rear of the operating device 1000 without directly shining light into the front of the cooking equipment. Such ambient lighting can also provide indicator lighting to indicate that the cooking equipment is in standby mode and that the operating device can be operated.

[0390] In addition, the ambient lighting provided by the light-emitting component 1700 can provide ambient lighting that enhances the aesthetics of the operating device, and can also provide lighting that allows the operating device to be operated even in dark environments.

[0391] [Structure of the socket component]

[0392] Figure 15 It is Figure 14 The socket component shown is separated and presented in an exploded perspective view. Figure 16 It is shown Figure 15 The front view of the socket component is shown. Additionally... Figure 17 It is shown Figure 15 The side view of the socket component shown. Figure 18 It is shown schematically. Figure 14 The front view of the structure of the first control substrate is shown. Figure 19 This is a schematic diagram illustrating the configuration of a cooking apparatus according to an embodiment of the present invention.

[0393] Reference Figures 14 to 19 The insertion member 1600 may include an outer support portion 1610. The outer support portion 1610 may be formed to include a surface extending in the front-rear direction. In this embodiment, the outer support portion 1610 is shown as being formed in a generally flat cylindrical shape. Such an outer support portion 1610 may be disposed on the outer side of the knob 1300 in the diametrical direction, and at least a portion of the knob 1300 may be inserted into the area enclosed by the outer support portion 1610.

[0394] The knob 1300 can be engaged with the outer support portion 1610 in such a way that its rear end contacts the inner circumferential surface of the outer support portion 1610. At this time, the rear end of the knob 1300 can be slidably engaged with the inner circumferential surface of the outer support portion 1610. Thus, the knob 1300 can be supported on the socket member 1600 in a way that allows rotation and axial movement.

[0395] An insertion groove 1611 may be provided in the inner circumferential surface of the outer support portion 1610, that is, in the inner surface of the outer support portion 1610 adjacent to the rear end of the knob 1300. The insertion groove 1611 may be recessed in the centrifugal direction on the inner circumferential surface of the outer support portion 1610. The rear end of the knob 1300 may be inserted into such an insertion groove 1611, thereby realizing the engagement between the knob 1300 and the socket member 1600. This will be described in detail later.

[0396] Additionally, the socket member 1600 may also include an inner support portion 1620. The inner support portion 1620 may include a surface extending in the front-rear direction. In this embodiment, the inner support portion 1620 is shown as being formed in a generally flat cylindrical shape. Such an inner support portion 1620 may be disposed inside the outer support portion 1610 in the diametrical direction.

[0397] The inner support portion 1620 can be disposed between the encoder 1200 and the outer support portion 1610. Furthermore, the encoder 1200 can be inserted into the area enclosed by the inner support portion 1620. That is, the inner support portion 1620 can be disposed inside the outer support portion 1610 in a manner that surrounds the outer periphery of the encoder 1200.

[0398] Additionally, the socket member 1600 may also include a first connecting support portion 1630 that supports the outer support portion 1610 and the inner support portion 1620. The first connecting support portion 1630 can connect the outer support portion 1610 and the inner support portion 1620 to each other and can support the outer support portion 1610 and the inner support portion 1620.

[0399] The first connecting support portion 1630 may be disposed behind the outer support portion 1610 and the inner support portion 1620. In such a first connecting support portion 1630, the first connecting support portion 1630 may also form the back side of the socket member 1600 and support the outer support portion 1610 and the inner support portion 1620 behind them.

[0400] According to this embodiment, the socket member 1600 is disposed inside the front panel 350 of the door and can be combined with the first control substrate 500 disposed inside the front panel 350 of the door. At this time, the first connecting support portion 1630 forming the back side of the socket member 1600 can become a mating surface that contacts the first control substrate 500 when the socket member 1600 is disposed on the first control substrate 500.

[0401] The first connecting support portion 1630 may include a flange-shaped portion 1631 and a rib-shaped portion 1633. The flange-shaped portion 1631 may be formed to protrude from the inner support portion 1620 in a centrifugal direction. Such a flange-shaped portion 1631 may be formed in a shape that protrudes from the inner support portion 1620 in a flange shape.

[0402] Furthermore, the rib-shaped portion 1633 connects the flange-shaped portion 1631 and the outer support portion 1610. The rib-shaped portion 1633 can be formed as a rib protruding from the flange-shaped portion 1631 in a centrifugal direction. Between the flange-shaped portion 1631 and the outer support portion 1610, a plurality of rib-shaped portions 1633 can be arranged radially. The rib-shaped portions 1633 provided in this manner can suppress the increase in the overall weight of the socket member 1600, while effectively improving the overall strength of the socket member 1600.

[0403] Additionally, the inner support portion 1620 can be disposed behind the shaft engagement portion 1310 of the knob 1300. Such an inner support portion 1620 suppresses excessive movement of the knob 1300 by supporting the shaft engagement portion 1310 of the knob 1300, which moves rearward, thereby preventing excessive load from being applied to the shaft 1100 and the encoder 1200.

[0404] In addition, the inner support portion 1620 is supported by the first connecting support portion 1630, and some elasticity can be provided between the inner support portion 1620 and the first connecting support portion 1630.

[0405] According to this embodiment, the socket member 1600 can be made of plastic material, and the outer support portion 1610, the inner support portion 1620 and the first connecting support portion 1630 can be integrally formed.

[0406] Furthermore, the flange-shaped portion 1631 and the rib-shaped portion 1633 of the first connecting support portion 1630 can be connected by a skirt-shaped portion 1635. The skirt-shaped portion 1635 can be formed to protrude rearward from the outer peripheral surface of the flange-shaped portion 1631. Thus, the flange-shaped portion 1631 and the rib-shaped portion 1633 can be connected in a "┐" shape, and elasticity can be provided between the inner support portion 1620 and the first connecting support portion 1630, and between the outer support portion 1610 and the first connecting support portion 1630.

[0407] Therefore, when the knob 1300 is pressed and the inner support portion 1620 is pushed backward, the inner support portion 1620 can elastically support the knob 1300 and stably suppress the rearward movement of the knob 1300. Furthermore, when the force pressing the knob 1300 is released, the inner support portion 1620 returns to its original state, and the force required to return the knob 1300 to its original position can be applied to the knob 1300.

[0408] On the other hand, a light-transmitting hole 1640 may be provided in the socket member 1600. The light-transmitting hole 1640 may be formed to penetrate the socket member 1600 in the front-back direction, and more specifically, to penetrate the outer support portion 1610. Such a light-transmitting hole 1640 may be configured to overlap with the light-emitting member 1700 provided on the first control substrate 500 in the front-back direction.

[0409] According to this embodiment, a plurality of light-emitting members 1700 may be provided on the first control substrate 500. Such light-emitting members 1700 may be disposed behind the outer support portion 1610 and may be disposed at a position overlapping with the outer support portion 1610 in the front-back direction. That is, the plurality of light-emitting members 1700 may be disposed behind the outer support portion 1610 along the peripheral direction of the outer support portion 1610.

[0410] Furthermore, a plurality of light-transmitting holes 1640 can be provided on the outer support portion 1610, and the plurality of light-transmitting holes 1640 can be arranged to overlap with the plurality of light-emitting members 1700 in the front-back direction. The arrangement of the light-emitting members 1700 and the light-transmitting holes 1640 can be achieved by inserting one light-emitting member 1700 into the interior of one light-transmitting hole 1640.

[0411] Therefore, light emitted from each light-emitting element 1700 can pass through the insertion member 1600 and illuminate forward via the light-transmitting holes 1640 disposed in front of each light-emitting element 1700. That is, the movement path of light emitted from each light-emitting element 1700 can be guided by the light-transmitting holes 1640 disposed in front of it. Thus, it is possible to clearly identify from the outside of the operating device 1000 which of the plurality of light-emitting elements 1700 is lit.

[0412] Additionally, the socket member 1600 may also include a first engaging portion 1650. The first engaging portion 1650 may include a first protruding protrusion 1651 and a first engaging protrusion 1653. The first protruding protrusion 1651 may be formed to protrude from the outer support portion 1610 in a centrifugal direction. Furthermore, the first engaging protrusion 1653 may be formed to protrude rearward from the first protruding protrusion 1651.

[0413] The first engagement protrusion 1653 can be inserted into the insertion hole 510 formed in the first control substrate 500 to engage, thereby realizing the engagement between the socket member 1600 and the first control substrate 500.

[0414] The position of the first coupling portion 1650 on the socket member 1600 can be determined after taking into account the positions of the light-transmitting holes 1640 and the light-emitting members 1700. That is, the first coupling portion 1650 is preferably positioned such that when the first coupling protrusion 1653 is inserted into the insertion hole 510 of the first control substrate 500 and coupled, the positions of the plurality of light-transmitting holes 1640 and the plurality of light-emitting members 1700 are aligned front to back.

[0415] Therefore, the first connecting portion 1650 can guide the socket member 1600 to its position on the first control substrate 500. That is, by simply inserting the first connecting portion 1650 into the first control substrate 500, the socket member 1600 can be guided to a preset position.

[0416] Additionally, the socket member 1600 may also include a second engaging portion 1660. The second engaging portion 1660 may include a second protruding protrusion 1661 and a second engaging protrusion 1663. The second protruding protrusion 1661 may be formed to protrude from the outer support portion 1610 in a centrifugal direction. Furthermore, the second engaging protrusion 1663 may be formed to protrude forward from the second protruding protrusion 1661.

[0417] The second connecting portion 1660 is used to connect the front cover member 1800 and the insertion member 1600, which will be described later. The second protruding protrusion 1661 can be inserted into the front cover member 1800 for connection, thereby realizing the connection between the front cover member 1800 and the insertion member 1600.

[0418] The socket member 1600 may be provided with a plurality of first connecting portions 1650 and second connecting portions 1660. In this embodiment, it is shown as an example that the socket member 1600 is provided with two first connecting portions 1650 and four second connecting portions 1660. However, the present invention is not limited thereto, and the number of first connecting portions 1650 and second connecting portions 1660 may be increased or decreased as needed.

[0419] Additionally, the socket member 1600 may also include a third connecting portion 1670. The third connecting portion 1670 may be formed to protrude rearward from the first connecting support portion 1630, and more specifically, from the flange-shaped portion 1631. Such a third connecting portion 1670 may be formed in the shape of a hook.

[0420] The third connecting part 1670 can be connected to the first control substrate 500 by being inserted into the first control substrate 500 through the fastening hole 520 formed in the first control substrate 500, thereby the insertion member 1600 can be fixed to the first control substrate 500.

[0421] A plurality of third coupling portions 1670 may be provided in the socket member 1600. The plurality of third coupling portions 1670 may be arranged at predetermined intervals along the peripheral direction of the flange-shaped portion 1631. Since the plurality of third coupling portions 1670 arranged as described above are coupled to the first control substrate 500 at a plurality of positions, the coupling between the socket member 1600 and the first control substrate 500 can be stably achieved.

[0422] [Knob Structure]

[0423] Reference Figures 12 to 14 The knob 1300 is configured to be rotated by the user, and the knob 1300 can be connected to the shaft 1100 via the shaft coupling 1310. Such a knob 1300 may also include a skirt 1320.

[0424] The skirt portion 1320 may be disposed on the outer side of the shaft connection portion 1310 in the diametrical direction. Such a skirt portion 1320 may include a surface extending in the front-rear direction. In this embodiment, the skirt portion 1320 is shown as a hollow cylindrical shape. The knob 1300, which includes such a shaft connection portion 1310 and skirt portion 1320, may be provided in a form in which the shaft connection portion 1310 and skirt portion 1320 form concentric circles.

[0425] Additionally, the knob 1300 may also include a second connecting support portion 1330. The second connecting support portion 1330 is disposed behind the shaft coupling portion 1310 and may be configured as a disc shape that connects the shaft coupling portion 1310 and the skirt portion 1320 together behind the shaft coupling portion 1310.

[0426] The second connecting support 1330 provided as described above can connect the shaft joint 1310 and the skirt 1320 together, and can also support the skirt 1320 to prevent the skirt 1320 from sinking in the centripetal direction.

[0427] In addition, the second connecting support portion 1330 can be configured to be adjacent to the front of the inner support portion 1620 provided on the socket member 1600, and can also be the part that presses the inner support portion 1620 backward when the knob 1300 moves backward.

[0428] Additionally, the operating device 1000 of this embodiment may also include a knob cover 1350. The knob cover 1350 may be formed into a cylindrical shape that is open at its rear. Such a knob cover 1350 may be attached to the outer peripheral surface of the skirt 1320 and surround the knob 1300 from the outside in the diametrical direction.

[0429] According to this embodiment, a connecting groove 1321 may be formed on the outer peripheral surface of the skirt portion 1320. The connecting groove 1321 may be formed to be recessed from the outer peripheral surface of the skirt portion 1320 in a centripetal direction. The knob cover 1350 is disposed on the skirt portion 1320 in a state of being inserted into the connecting groove 1321.

[0430] At this time, the knob cover 1350 can be provided on the knob 1300 in a manner that does not protrude from the skirt 1320 in the centrifugal direction. That is, the knob cover 1350 can be formed on the skirt 1320 to form the same plane as the outermost side of the skirt 1320 in the centrifugal direction near the knob cover 1350.

[0431] The knob cover 1350 may include a front portion 1360 and a side portion 1370. The front portion 1360 may include a surface intersecting an axis extending in the front-rear direction.

[0432] The front surface of the front portion 1360 can be formed by a flat surface, which is the same plane as the front surface of the door front portion 350. Furthermore, when the knob cover 1350 is provided on the knob 1300, the back surface of the front portion 1360 can contact the front end of the shaft connection portion 1310 and the skirt portion 1320. Since the back surface of the front portion 1360 contacts the front end of the shaft connection portion 1310 and the skirt portion 1320, the front-rear position of the knob cover 1350 provided on the knob 1300 can be guided.

[0433] On the other hand, the knob cover 1350 is the part that the user holds in their hand to operate the knob 1300, and corresponds to the part that forms the appearance of the knob 1300. Therefore, the knob cover 1350 should not only be made of a material and shape suitable for the user to hold and operate, but its appearance should also be aesthetically pleasing.

[0434] In view of this, in this embodiment, the side portion 1370 forming the side appearance of the knob cover 1350 can be configured such that its outer peripheral surface forms the same plane as the outer peripheral surface of the skirt portion 1320 not covered by the knob cover 1350. In addition, the front portion 1360 forming the front appearance of the knob cover 1350 can be configured such that its front surface forms the same plane as the front surface of the pressing portion 1410 of the button 1400.

[0435] Therefore, the operating device 1000 of this embodiment has a simple and smooth appearance, and has no protruding or recessed parts, thereby improving user satisfaction through aesthetics.

[0436] [Structure of the front cover component]

[0437] The operating device 1000 of this embodiment may further include a front cover member 1800. The front cover member 1800 may be disposed on the outer side of the knob 1300 in the diametrical direction. In addition, the front cover member 1800 may be disposed in front of the front face of the door 350 so as to protrude towards the front of the door 300.

[0438] The front cover member 1800 can be disposed on the outer side of the knob 1300 in the diametrical direction, and can be configured to surround the knob 1300 from its outer side in the diametrical direction. In this embodiment, the front cover member 1800 is shown as an example of being formed into a ring shape that surrounds the knob 1300 from its outer side in the diametrical direction.

[0439] Additionally, the front cover member 1800 is disposed in front of the socket member 1600 and can be attached to the front of the socket member 1600. Such a front cover member 1800 can be used to shield the socket member 1600 from the front, and more specifically, to shield the outer support portion 1610.

[0440] The annular front cover member 1800 can be shaped to correspond to the shape of the outer support portion 1610 when viewed from the front. Such a front cover member 1800 can be integrated with the insertion member 1600 to cover the outer support portion 1610 from the front. Thus, the front of the light-transmitting hole 1640 formed in the outer support portion 1610 can be shielded by the front cover member 1800, thereby shielding the light-transmitting hole 1640 and the light-emitting member 1700 behind it, making them invisible from the outside.

[0441] Furthermore, the front cover member 1800 can be made of a light-transmitting or semi-light-transmitting material. In this embodiment, the front cover member 1800 is shown as being made of a semi-light-transmitting material with a metallic texture. Such a front cover member 1800 serves to shield the socket member 1600, the light-transmitting hole 1640 formed therein, and the light-emitting member 1700 from being exposed to the outside, and can also softly diffuse the light emitted by the light-emitting member 1700.

[0442] That is, the front cover component 1800 can be used as a decorative material to prevent parts that may spoil the aesthetics from being unnecessarily exposed to the outside of the door 300, and the metallic texture can not only make the corresponding finishing part look more high-end, but also make the light shining through the corresponding part diffuse softly.

[0443] With such a front cover component 1800, not only can the aesthetics of the operating device 1000 and its surrounding parts be further improved, but the indicator lights provided by the operating device 1000 can also be provided in a softer and more aesthetically pleasing form.

[0444] The lighting of each light-emitting component 1700 can be linked with the rotation of the shaft 1100.

[0445] As an example, as the axis 1100 rotates, the corresponding light-emitting component 1700 can be lit up. If the axis 1100 continues to rotate, the other corresponding light-emitting component 1700 can be lit up.

[0446] At this time, the rotation of shaft 1100 can be detected by encoder 1200. In this way, the information about the rotation of shaft 1100 obtained by encoder 1200 can be generated as an operation signal. The control unit provided on the first control board 500 can receive the information and control the lighting of light-emitting component 1700.

[0447] On the other hand, the connection between the front cover member 1800 and the insertion member 1600 can be achieved by an insertion connection. For this purpose, a connecting protrusion 1810 can be provided on the front cover member 1800. The connecting protrusion 1810 can be formed to protrude rearward from the front cover member 1800.

[0448] The second connecting portion 1660 of the socket member 1600, more specifically, the second protruding protrusion 1661, can be inserted into the connecting protrusion 1810. The connection between the connecting protrusion 1810 and the second connecting portion 1660, configured in this way, can realize the connection between the front cover member 1800 and the socket member 1600.

[0449] A plurality of connecting protrusions 1810 may be provided on the front cover member 1800. In this case, the arrangement position and number of connecting protrusions 1810 can be determined corresponding to the arrangement position and number of the second connecting portion 1660.

[0450] On the other hand, as described above, an insertion groove 1611 may be provided in the insertion member 1600 that is combined with the front cover member 1800. The insertion groove 1611 may be formed by recessing into the inner peripheral surface of the outer support portion 1610 in the centrifugal direction.

[0451] Correspondingly, a protrusion 1340 may be provided on the knob 1300. The protrusion 1340 may be formed to protrude in a centrifugal direction from the rear end of the skirt 1320. The protrusion 1340 formed in this way can be inserted into the insertion groove 1611, thereby slidably engaging with the inner peripheral surface of the outer support portion 1610.

[0452] According to this embodiment, the insertion slot 1611 can be formed to open towards the interior and front of the socket member 1600. Additionally, a front cover member 1800 can be disposed in front of the socket member 1600 to cover the front opening in the insertion slot 1611. Furthermore, the protrusion 1340 can be inserted into the space enclosed by the insertion slot 1611 and the front cover member 1800.

[0453] The protrusion 1340 can be inserted into the interior of the insertion slot 1611 through the open front side of the insertion slot 1611, thereby allowing the knob 1300 to be positioned in the socket member 1600 in a manner that allows it to move in the front-rear direction. Furthermore, as described above, by providing a front cover member 1800 in front of the socket member 1600 where the knob 1300 is located, the forward movement of the knob 1300 can be restricted, and the knob 1300 can be prevented from disengaging.

[0454] [Structure of the hinge assembly]

[0455] Reference Figure 3The hinge assemblies 800 can be respectively disposed on both sides of the housing 100. In other words, the hinge assemblies 800 can be respectively disposed on both sides of the housing 100 in the left-right direction, so as to be disposed on the outer sides of the left and right sides of the tray 200. The rear side of the door top surface 310 can be rotatably connected to each of the hinge assemblies 800 disposed on both sides of the housing 100.

[0456] That is, the left and right corners of the rear side of the top surface of the door 310 are rotatably connected to the hinge assemblies 800 disposed on both sides of the housing 100. The door 300 rotates in the vertical direction around the rear side of the top surface of the door 310, which is rotatably connected to the hinge assembly 800, thereby opening and closing the top and front surfaces of the housing 100.

[0457] Each hinge assembly 800 may include a hinge housing 830, a hinge portion 810, and a mounting protrusion 820.

[0458] The hinge housing 830 forms the exterior of the hinge assembly 800. Furthermore, the hinge housing 830 can accommodate the hinge portion 810, a portion of the mounting protrusion 820, and the conversion output portion 840. Various structures for supporting the hinge portion 810 and a cooling flow path 850 (described later) can be formed within this hinge housing 830. Figure 54 )wait.

[0459] The hinge portion 810 can be provided in the hinge housing 830 in a manner that allows for positional changes. Such a hinge portion 810 can be provided in the hinge housing 830 in a manner that allows it to rotate along a track corresponding to the rotation track of the door 300. The upper end of the hinge portion 810 can engage with the door 300. As described above, the hinge portion 810 engaged with the door 300 can be linked to the rotation of the door 300, thereby changing the posture of the hinge portion 810. Furthermore, the rotation track and range of the door 300 engaged with the hinge portion 810 can be guided by the hinge portion 810.

[0460] Structures in cooking equipment to prevent tipping

[0461] The cooking apparatus of this embodiment includes various configurations for preventing the cooking apparatus from tipping forward.

[0462] The following text will detail the various components that prevent the cooking equipment from tipping forward when the door 300 is opened.

[0463] Figure 20 This is a diagram showing the change in the center of gravity of a cooking appliance when the door is open.

[0464] Reference Figure 3 and Figure 20The hinge portion 810 is disposed on two sides 120 and 130 of the housing 100, and is disposed on the side adjacent to the rear side 140 of the housing 100. That is, the hinge portion 810 is disposed at the rear of both sides of the housing 100.

[0465] Such a hinge portion 810 is combined with the door 300 and is attached to the rear side of the top part of the door 310. That is, the hinge portion 810 is attached to the rear side of both sides of the top part of the door 310, and the door 300 can open or close the cooking chamber 105 while rotating in the vertical direction with the rear side of the top part of the door 310 that is combined with the hinge portion 810 as the center.

[0466] The door 300 is rotatable about the rear side of the top surface 310 of the door, such that the door 300 is located further rearward in the open state of the front and top surfaces of the housing 100 (hereinafter referred to as the "open state") than in the closed state of the front and top surfaces of the housing 100 (hereinafter referred to as the "closed state").

[0467] As described above, the door 300 rotates around the rear side of the top surface 310 of the door, so that when the door is open, its position can be more rearward than when it is closed.

[0468] As described above, when the door 300 is positioned relatively rearward in the open state, the door 300 can shift the center of gravity of the cooking appliance from the center in the front-rear direction of the cooking appliance to the rearward position.

[0469] That is, in order to prevent the cooking equipment from tipping forward when the door 300 is opened, the first configuration is that the door 300 rotates around the rear side of the top part 310 of the door. Therefore, compared with the closed state, the position of the door 300 in the open state is biased to the rear. As a result, when the door 300 is in the open state, the center of gravity of the cooking equipment shifts from the center in the front-rear direction of the cooking equipment to the rear (G1→G1').

[0470] On the other hand, when observing the structure of the door 300 itself, the door 300 is provided in a form in which the vertical length of the front face 350 is less than the front-back length of the top face 310. That is, when the door 300 is in the closed state, the vertical length of the front face 350 is less than the front-back length of the top face 310.

[0471] Therefore, in door 300, the volume of the top part 310 is greater than that of the front part 350. Consequently, the weight of the top part 310 accounts for a greater proportion of the total weight of door 300 than that of the front part 350. As a result, the center of gravity of door 300 is shifted rearward (G2→G2') compared to the center of door 300 in the front-rear direction.

[0472] As the door 300 rotates backward to open, its center of gravity gradually shifts backward. The front face 350 of the door 300 is positioned at the front, while the top face 310 is positioned behind it.

[0473] Therefore, the greater the proportion of the weight of the top part 310 of the door 300 in the total weight of the door 300, the greater the degree to which the center of gravity of the door 300 moves backward when the door 300 rotates backward.

[0474] In other words, the greater the proportion of the weight of the top part 310 of the door 300 in the total weight of the door 300, the faster the center of gravity of the door 300 can move backward when the door 300 rotates backward. In addition, as mentioned above, as the center of gravity of the door 300 moves backward, the overall center of gravity of the cooking equipment can also move backward more quickly.

[0475] That is, in order to prevent the cooking equipment from tipping forward when the door 300 is opened, the second configuration is that the door 300 is provided in such a way that the vertical length of the front part 350 is less than the front-back length of the top part 310. Therefore, when the door 300 is turned backward, the center of gravity of the door 300 and the cooking equipment can move backward more quickly.

[0476] On the other hand, the door 300 is provided with a first heating part 400 and a viewing window W, which are disposed on the top part 310 of the door.

[0477] As described above, the viewing window W may include a pair of glass panes 330, 335 (see reference). Figure 11 Glass is typically made of a heavier material. Therefore, when a viewing window W formed of glass is positioned on the top surface 310 of a door, the weight of the top surface 310 inevitably increases accordingly.

[0478] Furthermore, the viewing window W in this embodiment may include a pair of glass panes 330 and 335, i.e., two layers of glass, and therefore the weight of the top surface 310 of the door inevitably increases accordingly.

[0479] As described above, with the viewing window W disposed on the top surface 310 of the door, the proportion of the weight of the top surface 310 in the total weight of the door 300 will increase by an amount corresponding to the weight of the glass forming the viewing window W.

[0480] Additionally, a pair of first heating elements 400 are disposed on the bottom side of the top surface of the door portion 310. The first heating elements 400 are respectively disposed on the front outer side and the rear outer side of the viewing window W. One of the pair of first heating elements 400 is disposed on the rear side of the top surface of the door portion 310 adjacent to the hinge portion 810.

[0481] As described above, since the first heating element 400 is disposed on the top part 310 of the door, the proportion of the weight of the top part 310 in the total weight of the door 300 will further increase by an amount corresponding to the weight of the first heating element 400.

[0482] Therefore, when the door 300 rotates backward, the center of gravity of the door 300 and the cooking equipment can move backward more quickly in correspondence with the increase in weight on the top surface 310 side of the door due to the first heating element 400.

[0483] Furthermore, since the center of gravity of the door 300 can be moved further rearward due to the first heating part 400 located on the rear side of the top part 310 of the door adjacent to the hinge part 810, the center of gravity of the door 300 and the cooking appliance can move rearward more quickly when the door 300 rotates rearward.

[0484] That is, in order to prevent the cooking equipment from tipping forward when the door 300 is opened, the third configuration is that the first heating part 400 and the viewing window W are arranged on the top part 310 of the door, so that when the door 300 is turned backward, the center of gravity of the door 300 can move backward more quickly.

[0485] In summary, the door 300 of this embodiment is provided such that the position of the door 300 can move backward when it is rotated backward, and is provided in such a way that the vertical length of the front part 350 is less than the front-back length of the top part 310, and is provided in such a way that the first heating part 400 and the viewing window W are arranged on the top part 310.

[0486] The door 300 is configured such that when the cooking chamber 105 is opened and the tray 200 is led out from the front, the door 300 itself moves to the rear side of the cooking equipment, and the center of gravity of the door 300 moves rapidly to the rear as the door 300 rotates to the rear.

[0487] The door 300, arranged in this way, shifts the center of gravity of the cooking equipment from the center in the front-to-back direction to the rear when the tray 200 is extended from the front after the cooking chamber 105 is opened, thereby significantly reducing the risk of the cooking equipment tipping over in front.

[0488] On the other hand, the door 300 rotates around the rear side of the door top part 310 that is connected with the hinge part 810. When the door 300 is in the open state, most of the load of the door 300 is applied to the hinge part 810 side.

[0489] Since the hinge part 810 is located on the rear side of the cooking appliance, when the door 300 is in the open state, most of the load of the door 300 is concentrated on the rear side of the cooking appliance.

[0490] Therefore, when the door 300 is in the open state, the center of gravity of the cooking equipment moves to the rear side of the cooking equipment as most of the load of the door 300 is concentrated on the rear side of the cooking equipment.

[0491] In other words, when the door 300 is in the open state, in addition to the effects caused by the change in the position of the door 300 itself and the change in the center of gravity of the door 300 itself, the fact that most of the load of the door 300 is concentrated on the rear side of the cooking equipment can further shift the center of gravity of the cooking equipment to the rear side.

[0492] That is, the fourth configuration provided to prevent the cooking equipment from tipping forward when the door 300 is opened is that the joint point between the door 300 and the hinge part 810 is located on the rear side of the cooking equipment, so that the effect of concentrating most of the load of the door 300 on the rear side of the cooking equipment can be further utilized.

[0493] The magnitude of the torque acting on one side of door 300 can be determined by the force acting on door 300 and the distance between the position of the force and the axis of rotation (the joint between the door and the hinge). At this point, unless another force is applied, it can be assumed that only gravity acts on door 300. Since gravity acts on the entire part of door 300, it can be assumed that gravity acts at the center of gravity of door 300. Therefore, it can be assumed that the farther the center of gravity of door 300 is from the joint between door 300 and hinge 810, the greater the torque (M1); and the closer the center of gravity of door 300 is to the joint between door 300 and hinge 810, the smaller the torque (M2).

[0494] According to this embodiment, as the door 300 rotates backward to open the cooking chamber 105, the center of gravity of the door 300 also moves further backward. Therefore, the magnitude of the torque acting on the side of the door 300 can also be reduced (M1→M2).

[0495] That is, when the door 300 is in the open state, the torque on the side of the door 300 can be reduced.

[0496] Therefore, in the cooking apparatus of this embodiment, by reducing the magnitude of the torque exerted by the door 300 on the cooking apparatus when the door 300 is opened, the risk of the cooking apparatus tipping forward can be significantly reduced.

[0497] That is, the fifth configuration, which is provided to prevent the cooking equipment from tipping forward when the door 300 is opened, is to configure the center of gravity of the door 300 to be biased towards the rear, so as to reduce the magnitude of the torque exerted by the door 300 on the cooking equipment.

[0498] [Configuration structure of door components]

[0499] According to this embodiment, an operating device 1000 and a first control board 500 are arranged on the front part 350 of the door, and a viewing window W and a first heating part 400 are arranged on the top part 350 of the door.

[0500] This configuration structure is not arbitrarily chosen, but rather designed to maximize the convenience and safety of the cooking equipment.

[0501] Therefore, the operating device 1000 is located on the front face 350 of the door rather than the top face 310. A viewing window W is provided on the top face 310, and the viewing window W occupies most of the area of ​​the top face 310, so it is difficult to find a suitable space in the top face 310 to arrange the operating device 1000.

[0502] In particular, given that most of the top surface of the door 310 is covered by glass 330, it is difficult to provide a portion of the top surface of the door 310 for setting up the operating device 1000.

[0503] In addition to the viewing window W, a first heating element 400 is provided in the top surface of the door 310. The first heating element 400 is a heat-generating component that generates high heat, and in order to suppress the temperature rise of the outer surface that the user may touch, most of the top surface of the door 310 is provided to be covered by glass 330.

[0504] Since the thermal conductivity of glass 330 is lower than that of the metal material forming the exterior skeleton of door 300, glass 330 is used to cover most of the top surface of the top surface of door top surface 310 in order to minimize the temperature rise of the outer surface of the top surface of door top surface 310 that may be touched by the user due to heat generated by the first heating element 400, etc.

[0505] Even if most of the top surface 310 of the door is not covered by the glass 330, but only part of the viewing window W is covered by the glass 330, the area where the operating device 1000 can be installed is limited to the outer area in the planar direction of the viewing window W.

[0506] However, since this area is directly above the first heating unit 400, if the operating device 1000 is installed in this area, the operating device 1000 will inevitably be exposed to high temperatures.

[0507] If the operating device 1000 is placed in such an environment, it will inevitably have an adverse effect on the various operating switches that constitute the operating device 1000, as well as the cables or electronic components that are electrically connected to the various operating switches.

[0508] In addition, due to the rising nature of hot air, the top surface of the door 310 is inevitably at a higher temperature than the front surface of the door 350. Moreover, considering that the first heating element 400 is provided on the top surface of the door 310, the temperature of the top surface of the door 310 is likely to be higher than the temperature of the front surface of the door 350 in most cases.

[0509] If the operating device 1000 is installed on the top surface 310 of such a door, it will not only have an adverse effect on the operating device 1000 itself, but also increase the risk of burns caused by the user coming into contact with the top surface 310 of the door during operation.

[0510] The first heating element 400 is positioned on the top surface of the door 310 as a result of the design, with the first heating element 400 positioned on top of the tray 200 facing the second heating element 600. As described above, only when the first heating element 400 is positioned on top of the tray 200 can the food placed on the tray 200 be heated evenly from above; therefore, the first heating element 400 must be positioned on the top surface of the door 310.

[0511] Furthermore, when the viewing window W is positioned on top of the cooking appliance, the user can observe the interior of the cooking chamber 105 from above through the viewing window W formed on the top of the cooking appliance. Therefore, the user can easily and conveniently check the cooking status of the food without lowering their posture or bending over. For this reason, the viewing window W must also be positioned on the top surface 310 of the door.

[0512] That is, when considering various situations, the first heating part 400 and the viewing window 400 are preferably arranged on the top part of the door 310, so that most of the area of ​​the top part of the door 310 is occupied by the first heating part 400 and the viewing window 400.

[0513] Taking these factors into consideration, the operating device 1000 is located on the front face of the door 350 rather than the top face of the door 310. Typically, the user faces the cooking appliance from the front and uses it. Therefore, if the operating device 1000 is located on the front face of the door 350 facing the user, the user can more easily identify the operating device 1000, and the user can operate the operating device 1000 more easily and conveniently.

[0514] Furthermore, compared to the top part 310, the front part 350 is a section that does not require the installation of various components that occupy a large volume. That is, since there are no heavy and large components such as the viewing window 400 or the first heating unit 400 in the front part 350, the interior of the front part 350 has a more spacious interior compared to the top part 310.

[0515] A first control board 500 is disposed in the space inside the front panel 350 of the door. As described above, since the first control board 500 is disposed inside the front panel 350 of the door, it has the following advantages.

[0516] The first control board 500 is provided with various components and circuits related to receiving operation signals input by the operation device 1000 and generating control signals for controlling the operation of the first heating unit 400 and the second heating unit 600.

[0517] If such a first control board 500 is disposed inside the front face portion 350 of the door, the operating device 1000 and the first control board 500 can be disposed very close to each other. The first control board 500 is configured to be electrically connected to the operating device 1000 in order to receive the operating signals input through the operating device 1000.

[0518] If the first control substrate 500 is positioned very close to the operating device 1000, an electrical connection between the first control substrate 500 and the operating device 1000 can be easily and effectively established. In particular, in this embodiment, the operating device 1000 can be electrically connected to the first control substrate 500 by being directly mounted on it, thus the connection between the operating device 1000 and the first control substrate 500 can be established very effectively.

[0519] In addition, as described above, the first control board 500 disposed inside the front face 350 of the door can also be disposed very close to the first heating part 400, so that an electrical connection between the first heating part 400 and the first control board 500 can be established very easily and effectively.

[0520] That is, as shown in this embodiment, if the operating device 1000 is disposed on the front face 350 of the door, the operating device 1000 can avoid the top face 310 of the door which does not have suitable space and be disposed in a more spacious part. Therefore, it has the following advantages: it can increase the design freedom of the size, number, position, etc. of the operating switch, reduce the impact of high temperature, thereby improving the operation stability and safety of the cooking equipment, and can establish an electrical connection between the operating device 1000, the first control board 500 and the first heating part 400 very easily and effectively.

[0521] On the other hand, as described above, if a viewing window W and a first heating element 400 are provided on the top part of the door 310, and an operating device 1000 and a first control board 500 are provided on the front part of the door 350, then the relatively heavier components are provided on the top part of the door 310, and the relatively lighter components are provided on the front part of the door 350.

[0522] That is, the relatively heavy viewing window W and the first heating unit 400 are disposed on the top part of the door 310, while the relatively light operating device 1000 and the first control board 500 are disposed on the front part of the door 350. Therefore, the top part of the door 310 is relatively heavier than the front part of the door 350, and as a result, the center of gravity of the door 300 will be further shifted to the rear side of the door 300.

[0523] Furthermore, since the door 300 is provided in a form where the length of the front face 350 in the vertical direction is less than the length of the top face 310 in the front-back direction, the center of gravity of the door 300 will be significantly biased towards the rear side of the door 300.

[0524] In addition, since the hinge part 810 is located on the rear side of the cooking device, when the door 300 is in the open state, most of the load of the door 300 will eventually be concentrated on the rear side of the cooking device.

[0525] Therefore, when the door 300 is in the open state, the center of gravity of the cooking equipment moves to the rear side of the cooking equipment as most of the load of the door 300 is concentrated on the rear side of the cooking equipment.

[0526] Therefore, even when the door is open, the likelihood of the cooking equipment's center of gravity tilting forward is reduced, thus significantly reducing the risk of the cooking equipment tipping over. This has the advantage of improving the safety and ease of use of the cooking equipment.

[0527] On the other hand, in this embodiment, as described above, the operating device 1000 is disposed on the door 300 instead of the housing 100.

[0528] According to this embodiment, the door 300 includes a top portion 310 disposed on the upper side and a front portion 350 disposed on the front side. Furthermore, since the viewing window W, which occupies a large portion of the door area in conventional cooking equipment, is disposed on the top portion 310, sufficient space can be provided in the front portion 350 for arranging the operating device 1000.

[0529] Furthermore, since components such as the viewing window W or the first heating unit 400 are not disposed on the front part of the door 350, sufficient space can be formed inside the front part of the door 350 for the installation of the first control board 500, which is a component that must be close to and connected to the operating device 1000.

[0530] As described above, the cooking apparatus of this embodiment provides an environment conducive to placing the operating device 1000 in the door 300, thus enabling an effective configuration of the operating device 1000 placed in the door 300.

[0531] Furthermore, as described above, since the operating device 1000 and the first control board 500 are disposed on the door 300, the electrical connection between the first heating part 400 disposed on the door 300, the operating device 1000 and the first control board 500 can be established more effectively.

[0532] That is, not only can the electrical connection between the first heating unit 400, the operating device 1000, and the first control board 500 be realized inside the door 300, but the length of the wiring used for this electrical connection can also be shortened. As a result, simple and neat wiring can be achieved, and such wiring can be realized inside the door 300 so that the wiring is not exposed to the outside.

[0533] In addition, as shown in this embodiment, if the operating device 1000 is located in the door 300, it is not necessary to provide space in the housing 100 for mounting the operating device 1000 and the first control board 500.

[0534] Therefore, the housing 100 can be designed to take into account only the size and shape of the cooking chamber 105 and the door 300 without having to consider the space for setting up the operating device 1000 and the first control board 500.

[0535] Therefore, the size of the housing 100 can be reduced by a corresponding amount to the removal of space used for setting the operating device 1000 and the first control board 500, and the size of the door 300 can also be provided in a larger size corresponding to the size of the housing 100.

[0536] Therefore, the cooking device of this embodiment can reduce the size of the housing 100 and provide a sufficiently large entrance and exit for the tray 200 and food to enter and exit, thereby having a compact appearance and providing further improved ease of use.

[0537] [Internal structure of the front of the door]

[0538] Figure 21 It is a three-dimensional view that separates and shows the various components that make up the front of the door.

[0539] It should be noted that, in Figure 21 The illustration of the first cooling fan is omitted.

[0540] Reference Figure 13 and Figure 21 The door 300 may include a door body portion 300a. The door body portion 300a can form the appearance of the door 300. In such a door body portion 300a, the portion forming the appearance of the top surface portion 310 and the portion forming the appearance of the front surface portion 350 can be formed... The shapes are arranged in a form that is integrally connected. Hereinafter, the part of the door body 300a that constitutes the appearance of the top surface 310 of the door is referred to as the first door body 310a, and the part of the door body 300a that constitutes the appearance of the front surface 350 of the door is referred to as the second door body 350a.

[0541] An accommodating space is formed inside the door body 300a. Such an accommodating space can accommodate the support panel 550 (described later) and electrical components such as the first control board 500 and temperature sensor 580 disposed on the support panel 550.

[0542] The accommodating space inside the door body portion 300a can open to one side. The accommodating space inside the first door body portion 310a formed in the door body portion 300a can open downwards. Furthermore, the accommodating space inside the second door body portion 350a formed in the door body portion 300a can open rearwards.

[0543] The door back cover 350b can cover the open side of the door body 300a. In this embodiment, the door back cover 350b is shown as being positioned behind the second door body 350a. Such a door back cover 350b can be positioned behind the second door body 350a and cover the open rear side of the second door body 350a.

[0544] As described later, the door back cover 350b can be combined with the door body 300a via the bracket 590. The door back cover 350b thus combined with the door body 300a can cover the open rear of the second door body 350a, and the space enclosed by the door body 300a and the door back cover 350b can protect the various electrical components housed inside the second door body 350a.

[0545] As described above, the support panel 550 can be disposed inside the space enclosed by the second door body portion 350a and the door rear cover 350b. That is, the support panel 550 can be disposed inside the front door portion 350. Such a support panel 550 can be combined with and fixed inside the door body portion 300a to at least one of the door body portion 300a and the door rear cover 350b.

[0546] For example, the support panel 550 can be attached to the second door body 350a and the door back cover 350b via the bracket 590. The support panel 550, thus attached to the second door body 350a and the door back cover 350b, can be fixed at a position spaced a predetermined distance from the second door body 350a and the door back cover 350b, and in particular, fixed at a position spaced a predetermined distance from the front of the second door body 350a. This will be explained in detail later.

[0547] The first control board 500 can be fixed to the support panel 550. That is, the first control board 500 can be fixed inside the second door body 350a by fixing it to the support panel 550. The encoder 1200 and the shaft 1100 can be provided on such a first control board 500, and the operating device 1000 can be connected to the shaft 1100.

[0548] A through hole 351a may be formed in the second door body portion 350a, which forms a channel required for the operation device 1000 to connect to the shaft 1100. A portion of the operation device 1000, which is disposed on the front side of the door 300, can be inserted into the interior of the second door body portion 350a through the through hole 351a.

[0549] [Structure of the Support Panel - Relevant Areas of the First Control Board]

[0550] Figure 22 It is Figure 21 The support panel shown is separated and presented in a front perspective view.

[0551] It should be noted that, in Figure 22 The illustration of the first cooling fan is omitted.

[0552] Reference Figure 13 , Figures 20 to 22 The support panel 550 can be formed in a shape similar to the front shape of the second door body 350a. For example, the front of the second door body 350a can be formed in a rectangular shape, and the support panel 550 can also be formed in a similar rectangular shape. Such a support panel 550 may include a main panel portion 551 and a position limiting portion.

[0553] The main panel portion 551 forms the framework supporting the panel 550. Such a main panel portion 551 can form a support surface supporting the second control substrate 500. In this embodiment, the main panel portion 551 is formed in a shape similar to the front shape of the second door body portion 350a, for example, in a rectangular shape.

[0554] The main panel portion 551 can be made of a rigid plastic material. Such a main panel portion 551 can be made of a lightweight insulating material and can have sufficient strength to support the first control substrate 500 and the various electrical components disposed on the first control substrate 500.

[0555] A position limiting part may be provided on the main panel portion 551. The position limiting part serves to limit the position of the first control substrate 500 supported by the main panel portion 551, and may be provided in the form of a structure protruding from the main panel portion 551.

[0556] Such a position limiting part may include at least one of a lower support part 553 and a side support part 555. In this embodiment, it is shown as an example where the position limiting part includes both the lower support part 553 and the side support part 555.

[0557] The lower support portion 553 may be disposed on the lower portion of the first control substrate 500, and the side support portion 555 may be disposed on the side of the first control substrate 500. According to this embodiment, the support panel 550 may include a first region 550a and a second region 550b.

[0558] The first region 550a is the region where the first control substrate 500 is disposed, and the second region 550b is the region where the first control substrate 500 is not disposed. A lower support portion 553 is disposed in the second region 550b and may also be disposed at the lower part of the first region 550a. Furthermore, a side support portion 555 may be disposed in the second region 550b and may also be disposed on the side of the first region 550a.

[0559] The vertical and lateral positions of the first control substrate 500 can be limited by the lower support portion 553 and the side support portion 555. That is, the vertical position of the first control substrate 500 is limited by the lower support portion 553 disposed at the lower part of the first region 550a, and the lateral position of the first control substrate 500 is limited by the side support portion 555 disposed at the side of the first region 550a, thereby guiding the placement position of the first control substrate 500 into the interior of the first region 550a.

[0560] At least one of the lower support portion 553 and the side support portion 555 may include a hook. The hook may include a main body portion 553a and a protrusion 553b. The main body portion 553a may be formed to protrude forward from the main panel portion 551.

[0561] At this time, the main body portion 553a can be formed to be elastically deformable in the lateral or vertical direction. In addition, the protrusion portion 553b can protrude from the main body portion 553a toward the first control substrate 500, and can protrude to a position that is spaced at a predetermined distance from the main panel portion 551.

[0562] In this embodiment, both the lower support portion 553 and the side support portion 555 are shown as examples of hooks. Therefore, the protrusion 553b of the hook included in the lower support portion 553 can protrude upward from the main body portion 553a. In addition, the protrusion 553b of the hook included in the side support portion 555 can protrude sideways from the main body portion 553a.

[0563] At this time, each protrusion 553b can protrude to a position spaced a predetermined distance from the main panel portion 551, and can protrude to a position spaced from the main panel portion 551 by an amount corresponding to the thickness of the first control substrate 500. A portion of the first control substrate 500 can be inserted into the space between the thus formed main panel portion 551 and the protrusions 553b. That is, the lower end of the first control substrate 500 can be inserted into the lower support portion 553, and the side end of the first control substrate 500 can be inserted into the side support portion 555.

[0564] Therefore, the position of the first control substrate 500 in the front-rear direction can be limited by the lower support portion 553 and the side support portion 555. That is, the rear of the first control substrate 500 can be supported by the main panel portion 551, and the front of the first control substrate 500 can be supported by the protrusion 553b, so that the position of the first control substrate 500 in the front-rear direction is limited.

[0565] In summary, the lateral position of the first control substrate 500 can be limited by the lower support portion 553 and the side support portion 555, and the front-rear position of the first control substrate 500 can be limited by the main panel portion 551 and the protrusion portion 553b.

[0566] As a result, the first control board 500 can be accurately positioned in the first region 550a, that is, positioned at a location designed for the configuration of the first control board 500, and can be stably fixed on the support panel 550.

[0567] In addition, the lower support portion 553 may include a plurality of hooks arranged at predetermined distances in the left-right direction. As a result, the lower part of the first control board 500 can be more stably supported by the lower support portion 553, and therefore, the first control board 500 can be more stably fixed on the support panel 550.

[0568] Additionally, the support panel 550 may also include a rib 552. The rib 552 protrudes forward from the main panel portion 551 and is disposed between the main panel portion 551 and the first control substrate 500. Such a rib 552 can be provided as a structure to further improve the structural rigidity of the support panel 550. Furthermore, the rib 552 can create a predetermined gap between the first control substrate 500 and the main panel portion 551, thereby also serving as a channel for providing heat dissipation for the first control substrate 500.

[0569] [Structure of the support panel - Areas related to other electrical components besides the first control board]

[0570] Figure 23 It is shown Figure 22 The rear perspective view of the back of the support panel shown. Figure 24This is a rear perspective view showing the setup status of the temperature sensor.

[0571] like Figures 21 to 24 As shown, the cooking device in this embodiment may also include a temperature sensor 580.

[0572] Temperature sensor 580 is provided for measuring the temperature inside cooking chamber 105. Such temperature sensor 580 may include an elongated rod-shaped sensor body 581 and a flange 583 protruding from the sensor body 581. Furthermore, the flange 583 may be formed in the form of a quadrilateral plate protruding from the sensor body 581 in a centrifugal direction.

[0573] The temperature sensor 580 can be disposed inside the front face 350 of the door in the form of being fixed to the support panel 550. For this purpose, the support panel 550 may also include a temperature sensor support 557.

[0574] The temperature sensor support 557 can be disposed in the second region 550b, that is, the region where the first control substrate 500 is not disposed. Such a temperature sensor support 557 supports the temperature sensor 580, thereby the temperature sensor 580 can be supported by the temperature sensor support 557 and can be disposed in the second region 550b.

[0575] The temperature sensor support 557 may include a second sidewall portion 557a. The second sidewall portion 557a may be formed to protrude rearward from the main panel portion 551. Furthermore, the interior of such a second sidewall portion 557a may be formed to extend through in the front-rear direction. For example, the second sidewall portion 557a may be formed as a quadrilateral pillar protruding rearward from the main panel portion 551 with its interior extending through in the front-rear direction.

[0576] Temperature sensor 580 can be inserted into the interior of the second sidewall portion 557a. At this time, the position of the flange 583 of temperature sensor 580 in the up-down and left-right directions can be limited by the second sidewall portion 557a.

[0577] Furthermore, the temperature sensor support 557 may also include a second support surface 557b. The second support surface 557b may protrude from the second sidewall portion 557a toward the interior of the second sidewall portion 557a, and may form a plane intersecting the front-rear direction. For example, the second support surface 557b may be formed in a form where a plane parallel to the main panel portion 551 protrudes toward the interior of the second sidewall portion 557a.

[0578] The flange 583 inserted into the interior of the second sidewall portion 557a can contact the second support portion 557b disposed behind the flange 583, thereby restricting the rearward movement of the temperature sensor 580.

[0579] That is, the position of the temperature sensor 580 inserted into the interior of the second side wall portion 557a in the up-down and left-right directions is restricted by the interference between the second side wall portion 557a and the flange 583, and the position in the front-back direction is restricted by the interference between the second support portion 557b and the flange 583, thereby allowing it to be stably mounted on the temperature sensor support portion 557.

[0580] Additionally, the temperature sensor support 557 may also include a protruding portion 557c. The protruding portion 557c may be formed to protrude forward from the second support surface 557b. That is, the second support surface 557b is disposed behind the main panel portion 551, and the protruding portion 557c can protrude forward from this second support surface 557b. In this case, the protruding portion 557c may be formed so that it does not protrude further forward than the main panel portion 551.

[0581] Inside the protruding post 557c, the fastening hole can be formed as a hollow shape extending in the front-rear direction, and such a fastening hole can open to the rear of the second support surface 557b. Furthermore, a fastening hole can also be formed on the flange 583. In this case, the fastening hole of the flange 583 can be formed at a position overlapping with the fastening hole of the protruding post 557c in the front-rear direction.

[0582] With the flange 583 in contact with the second support surface 557b so that the fastening holes of the flange 583 and the post 557c can overlap each other, when the screw passes through the fastening hole from the rear of the flange 583 and is fastened to the post 557c, the flange 583 can be tightly attached to the second support surface 557b and fixed to the temperature sensor support 557, thereby the temperature sensor 580 can be stably fixed on the support panel 550.

[0583] Additionally, the temperature sensor support 557 may also include a hook 557d. The hook 557d may protrude from the second side wall portion 557a toward the interior of the temperature sensor support 557, that is, toward the interior of the second side wall portion 557a, in an upward or downward direction.

[0584] For example, a hook 557d disposed on the lower side of the second sidewall portion 557a may protrude upwards, and a hook 557d disposed on the upper side of the second sidewall portion 557a may protrude downwards. In this embodiment, it is shown as an example where at least one hook 557d is disposed on both the lower and upper sides of the second sidewall portion 557a. Furthermore, such a hook 557d may be disposed in front of the second support surface 557b.

[0585] At this point, each hook 557d is positioned at a predetermined distance from the second support surface 557b, and can be positioned at a distance from the second support surface 557b corresponding to the thickness of a portion of the temperature sensor 580, more specifically, corresponding to the thickness of the flange 583. A portion of the temperature sensor 580, namely the flange 583, can be inserted into the space between the thus formed second support surface 557b and the hooks 557d.

[0586] This allows for the initial fixing of the temperature sensor 580, making the subsequent tightening of the temperature sensor 580 easier.

[0587] The temperature sensor 580, configured as described above, has its rear end protruding through the door back cover 350b and extending to the outside of the door 300. That is, the temperature sensor 580 can protrude from inside the door front portion 350 toward the rear of the door front portion 350 and protrude into the cooking chamber 105. As described above, the temperature sensor 580, with its rear end protruding to the outside of the door 300, can measure the temperature of the cooking chamber 105 from within the cooking chamber 105 (see reference). Figure 32 ).

[0588] Furthermore, the front of the sensor body 581 can protrude into the interior of the door 300 to connect with the first control board 500. That is, the front of the sensor body 581 can be electrically connected to the first control board 500 via a cable.

[0589] Therefore, the measurement result of the temperature sensor 580 can be sent to the first control board 500, and the first control board 500 can control the operation of the first heating unit 400 and the like based on the result, thereby adjusting the temperature inside the cooking chamber 105.

[0590] The temperature sensor support 557 can be formed to protrude rearward from the support panel 550. Correspondingly, a recess 351b can be provided on the door rear cover 350b. The recess 351b can be formed to be a portion of the door rear cover 350b located behind the temperature sensor support 557 that is recessed rearward. Such a recess 351b can be formed to be recessed rearward when viewed from the front and protruding rearward when viewed from the rear.

[0591] The temperature sensor support 577 can be accommodated in the space enclosed by the recess 351b. In addition, a through hole 352b can be formed in the recess 351b to allow the sensor body 581 to pass through the door back cover 350b.

[0592] Additionally, the support panel 550 of this embodiment may also include a cable fixing portion 558. The cable fixing portion 558 may be formed to protrude forward from the main panel portion 551 and may be disposed between the first control substrate 500 and the temperature sensor support portion 557. Such a cable fixing portion 558 can fix the cable used to connect the first control substrate 500 and the temperature sensor support portion 557 to each other on the support panel 550.

[0593] The cable fixing part 558 may include a pair of hooks. Furthermore, each hook may include a body part 558a and a protrusion 558b. The body part 558a may be formed to protrude forward from the main panel part 551.

[0594] At this time, the main body 558a can be formed to be elastically deformable in the lateral direction. In addition, the protrusion 558b can protrude from the main body 558a toward the adjacent hook.

[0595] That is, a pair of hooks are configured to face each other, and the protrusions 558b of each hook can be arranged to protrude towards each other. Thus, the gap between the front portions of the two hooks, which are the portions with protrusions 558b, can be formed to be much smaller than the gap between the rear portions of the two hooks, which are the portions with main body portions 558a. Preferably, the hooks can be configured such that the gap between the two protrusions 558b is narrower than the diameter of the cable, or that the two protrusions 558b are in contact with each other.

[0596] Therefore, the cable can be clamped into the cable fixing part 558 from the front, and the cable clamped into the cable fixing part 558 cannot be easily detached from the cable fixing part 558.

[0597] In addition, a plurality of cable fixing parts 558 may be arranged at predetermined intervals on the support panel 550.

[0598] According to this embodiment, the first control board 500 may be provided with a terminal 501 for connection between the cable and the first control board 500. Furthermore, such a terminal 501 may be disposed on a side of the first control board 500 that is biased downwards.

[0599] Reference Figure 13 , Figure 21 as well as Figure 22 The components related to the operating device 1000, such as the shaft 1100 and the encoder 1200, can be arranged on the top side of the first control board 500. Since the operating device is arranged on the top side of the front panel 350 of the door, the shaft 1100, encoder 1200, etc., connected to the operating device should be arranged on the top side of the first control board 500.

[0600] Because the handle 305 is positioned slightly downwards on the front of the door 350, it is difficult to ensure sufficient space for the operating device 1000 in that location. Furthermore, it should be considered that the operating device 1000 is most easily operated by the user if it is positioned as high up as possible.

[0601] If the handle 305 is positioned towards the top of the front face 350 of the door, then the operating device 1000 should be positioned below it. In this case, the presence of the handle 305 not only makes the operation of the operating device 1000 very inconvenient, but also makes it aesthetically unpleasing.

[0602] In addition, if the handle 305 is positioned towards the top on the front of the door 350, a great deal of force is required to open and close the door 300, and the operation is also very inconvenient.

[0603] For this reason, the position of the operating device 1000 can be determined to be at the top of the front face 350 of the door.

[0604] As described above, when the operating device 1000 is positioned at the top of the front panel 350 of the door, the shaft 1100, encoder 1200, etc., are positioned on the top side of the first control board 500. Furthermore, since the top area of ​​the first control board 500 is mostly occupied by the shaft 1100, encoder 1200, etc., the position of the terminal 501 can be determined to be a position on the lower part of the first control board 500.

[0605] On the other hand, the temperature sensor support 557 and the temperature sensor 580 mounted on the temperature sensor support 557 can be configured on the support panel 550 at a position biased towards the top. Such a temperature sensor 580 can be configured closer to the top than the communication module 570, and can be configured at a height closer to the shaft 1100 and encoder 1200 than the terminal 501. The specific reasons for configuring the temperature sensor 580 at a biased position on the support panel 550 will be described later.

[0606] As described above, with the height difference between temperature sensor 580 and terminal 501, the distance between temperature sensor 580 and terminal 501 also increases accordingly. As the distance between temperature sensor 580 and terminal 501 increases, the length of the cable connecting them should also increase accordingly, and the interior of door 300 may become complicated due to the longer cable.

[0607] Considering these aspects, this embodiment proposes a structure in which a plurality of cable fixing portions 558 are disposed on the lower part of the temperature sensor support portion 557. The plurality of cable fixing portions 558 disposed in this manner can fix cables that are arranged in the vertical direction based on the positional characteristics of the temperature sensor 580 and the terminal 501 at a plurality of positions.

[0608] Therefore, the cable connecting the temperature sensor 580 and the first control board 500 can be stably fixed on the support panel 550, thereby keeping the interior of the door 300 neater and tidier.

[0609] Additionally, the support panel 550 of this embodiment may also include a cable support portion 559. The cable support portion 559 may be formed to protrude forward from the main panel portion 551 and may be disposed on the outside of the first control substrate 500.

[0610] The cable fixing part 558 can support the cable connected to the first control board 500. The cable supported by the cable support part 559 can connect the first control board 500 and the first heating part, or it can connect the first control board 500 and the second control board.

[0611] The cable support portion 559 may include a first protrusion 559a and a second protrusion 559b. The first protrusion 559a may protrude forward from the main panel portion. Furthermore, the second protrusion 559b may protrude from the first protrusion 559a in a direction parallel to the main panel portion 551. In this case, the second protrusion 559b may be configured to be spaced apart from the main panel portion 551 by a predetermined distance.

[0612] A plurality of cable support portions 559 may be disposed in the support panel 550. The plurality of cable support portions 559 may be configured to be adjacent to the edge of the support panel 550. A portion of the plurality of cable support portions 559 may be configured to be adjacent to the lower edge of the support panel 550, and another portion of the cable support portions 559 may be configured to be adjacent to the side edge of the support panel 550.

[0613] According to this embodiment, the cable support portion 559 disposed adjacent to the lower edge of the support panel 550 and the cable support portion 559 disposed adjacent to the side edge of the support panel 550 may have different shapes. For example, the second protrusion 559b in the cable support portion 559 disposed adjacent to the lower edge of the support panel 550 may protrude in the upward or downward direction. In addition, the second protrusion 559b in the cable support portion 559 disposed adjacent to the side edge of the support panel 550 may protrude in the side direction.

[0614] The cable can be supported by the cable support 559 in such a way that it is inserted into the space enclosed by the first protrusion 559a and the second protrusion 559b. Thus, the cable's position can be guided to a region adjacent to the edge of the support panel 550. The cable, thus guided, can be positioned close to the edge of the support panel 550 and can be connected to the first control substrate 500.

[0615] As a result, the cable connected to the first control board 500 can be stably fixed to the support panel 550 with its configuration close to the edge of the support panel 550. This keeps the interior of the door 300 neater and tidier, and prevents unnecessary contact between the various components mounted on the first control board 500 and the cable.

[0616] Additionally, the support panel 550 may also include a support protrusion 560. The support protrusion 560 may protrude from the main panel portion 551 toward the door body portion 300a facing the main panel portion 551, and more specifically, toward the front of the second door body portion 350a.

[0617] The support protrusion 560 can be positioned closer to the lower part of the first control substrate 500. For example, the support protrusion 560 can be positioned adjacent to the lower edge of the support panel 550.

[0618] Such a support protrusion 560 can interfere with the front of the second door body 350a and serves to guide the spacing between the front of the second door body 350a and the support panel 550. In addition, the support protrusion 560 can maintain the spacing between the front of the second door body 350a and the support panel 550.

[0619] According to this embodiment, a shaft 1100 and an encoder 1200 are disposed in the upper region of the first control board 500. In addition, a socket member 1600 surrounding the shaft 1100 and the encoder 1200 is also disposed in the upper region of the first control board 500.

[0620] The rear side of the insertion member 1600 can be attached to the first control base plate 500, and the front side of the insertion member 1600 can contact the front side of the second door body 350a. That is, the insertion member 1600 is sandwiched between the front side of the second door body 350a and the support panel 550, and the gap between the front side of the second door body 350a and the support panel 550 can be maintained by the insertion member 1600.

[0621] As a result, the upper region of the support panel 550 can be supported by the socket member 1600 to prevent bending toward the front of the second door body 350a. Conversely, the front of the second door body 350a can also be supported by the socket member 1600 to prevent bending toward the support panel 550.

[0622] However, there is a risk that the lower region of the support panel 550, which is not equipped with a structure such as the socket member 1600, may bend towards the front of the second door body 350a. Additionally, there is also a risk that the lower region of the front of the second door body 350a may bend towards the support panel 550.

[0623] For example, when the front of the second door body 350a is pressed and bent, or when the back cover 350b is pressed and bent, the gap between the front of the second door body 350a and the support panel 550 may become too narrow. In this case, the various components mounted on the first control board 500 may also be damaged, and the front shape of the second door body 350a may change, which may detract from the aesthetics of the door 300.

[0624] Considering these aspects, in this embodiment, a support protrusion 560 is provided on the lower side of the support panel 550. The support protrusion 560 serves to maintain the gap between the front of the second door body 350a and the support panel 550, and also serves to support the front of the second door body 350a to prevent the front of the second door body 350a from bending backward.

[0625] In summary, the insertion member 1600 can be disposed on the upper side of the support panel 550 to support the front of the second door body 350a and the upper side of the support panel 550, and the support protrusion 560 can be disposed on the lower side of the support panel 550 to support the front of the second door body 350a and the lower side of the support panel 550.

[0626] As a result, the support panel 550 and the first control base plate 500 disposed on the support panel 550 can be stably maintained at a distance from the front of the second door body portion 350a, and can be fixed inside the door 300. In addition, the structural stability of the door 300 can be effectively improved, for example, the deformation of the front of the second door body portion 350a due to impact or pressure can be suppressed.

[0627] [The connection structure between the door, support panel, and door back cover]

[0628] Figure 25 It is Figure 21 The support structure is shown in a 3D view. Figure 26 This is a cross-sectional view showing the connection structure between the support panel and the door back cover. Additionally, Figure 27This is a cross-sectional view showing the connection structure between the front of the door body and the support panel. Figure 28 This is an enlarged view of a portion of the internal structure of the front of the door. It should be noted that... Figure 26 and Figure 27 The illustration of the first cooling fan is omitted.

[0629] Reference Figure 21 , Figure 22 as well as Figures 25 to 28 The cooking device in this embodiment may further include a support 590. The support 590 may be disposed between the front of the second door body 350a and the support panel 550. Such a support 590 can separate the support panel 550 and the front of the second door body 350a by a predetermined interval in the front-rear direction, and can connect the support panel 550 to the door body 300a.

[0630] On the other hand, in addition to the first region 550a and the second region 550b, the support panel 550 may also include a coupling region 550c. The coupling region 550c may be disposed on the outer sides of the regions including the first region 550a and the second region 550b in the left-right direction. For example, the coupling region 550c may be disposed on the lateral edge portions of the support panel 550.

[0631] The brackets 590 can be respectively disposed between the front of the second door body 350a and each joint area 550c. Each bracket 590 can be respectively joined to the joint area 550c. Each bracket 590 may include a first joint portion 591, a second joint portion 593, and a connecting portion 595.

[0632] The first joint portion 591 forms a joint surface parallel to the joint region 550c. For example, the first joint portion 591 can be formed as a planar quadrilateral with a length in the vertical direction greater than its length in the horizontal direction.

[0633] The second joint portion 593 can form a joint surface parallel to the front surface of the second door body portion 350a. For example, the second joint portion 593 can be formed into a quadrilateral planar shape similar to the first joint portion 591. In this case, the second joint portion 593 can be formed into a shape where its length in the vertical direction is shorter than that of the first joint portion 591, and its length in the horizontal direction is longer than that of the first joint portion 591.

[0634] In this embodiment, the front side of the second door main body 350a and the joint area 550c are arranged side by side in the front-rear direction as an example. Therefore, the first joint 591 and the second joint 593 can also be arranged side by side with each other in the front-rear direction.

[0635] The connecting portion 595 can connect the first coupling portion 591 and the second coupling portion 593, such that the first coupling portion 591 and the second coupling portion 593 are spaced apart by a predetermined interval in the front-rear direction. The connecting portion 595 can be disposed between the first coupling portion 591 and the second coupling portion 593. For example, the connecting portion 595 may form a plane traversing the first coupling portion 591 and the second coupling portion 593, and more preferably, form a quadrangular plane orthogonal to the first coupling portion 591 and the second coupling portion 593.

[0636] The bracket 590 may be provided in a form in which the first coupling portion 591, the second coupling portion 593, and the connecting portion 595 as described above are integrally connected. Such a bracket 590 may be arranged such that when viewed from above, the first coupling portion 591, the connecting portion 595, and the second coupling portion 593 are connected in a manner forming a "匚" shape.

[0637] In this embodiment, an example is illustrated in which a pair of brackets 590 are disposed between the front surface of the second door main body 350a and the support panel 550. For example, the coupling regions 550c are respectively disposed on the left side of the first region 550a and the right side of the second region 550b on the support panel 550, and the brackets 590 can be respectively disposed between the front surface of the second door main body 350a and the left coupling region 550c, and between the front surface of the second door main body 350a and the right coupling region 550c.

[0638] At this time, in the bracket 590 disposed on the left side among the pair of brackets 590, the connecting portion 595 can connect the left end of the first coupling portion 591 and the left end of the second coupling portion 593. In addition, in the bracket 590 disposed on the right side among the pair of brackets 590, the connecting portion 595 can connect the right end of the first coupling portion 591 and the right end of the second coupling portion 593.

[0639] For example, the bracket 590 disposed on the left side may be arranged such that the first coupling portion 591, the connecting portion 595, and the second coupling portion 593 are connected in a manner forming a "匚" shape. Furthermore, the bracket 590 disposed on the right side may be arranged such that the first coupling portion 591, the connecting portion 595, and the second coupling portion 593 are connected in a manner forming a "コ" shape.

[0640] On the other hand, either one of the first coupling portion 591 and the coupling region 550c can be provided with a guiding protrusion 561. In addition, the other of the first coupling portion 591 and the coupling region 550c can be provided with a guiding hole 591a.

[0641] The guide protrusion 561 can be formed to protrude from either the first joint portion 591 or the joint region 550c into the other of the first joint portion 591 and the joint region 550c. Furthermore, the guide hole 591a can be formed through the other of the first joint portion 591 and the joint region 550c. The guide protrusion 561 protruding from either the first joint portion 591 or the joint region 550c can be inserted into the guide hole 591a formed in the other of the first joint portion 591 and the joint region 550c.

[0642] In this embodiment, a guide protrusion 561 is provided in the engagement region 550c and a guide hole 591a is formed in the first engagement portion 591 as an example. Therefore, the guide protrusion 561 can protrude forward from the engagement region 550c, and such a guide protrusion 561 can be inserted into the guide hole 591a located in front of it and pass through the first engagement portion 591.

[0643] In this embodiment, a plurality of guide protrusions 561 are disposed in each engagement region 550c, and a plurality of guide holes 591a are disposed in each first engagement portion 591. For example, a pair of guide protrusions 561 may be disposed in each engagement region 550c at a predetermined interval in the vertical direction, and a pair of guide holes 591a may be disposed in each first engagement portion 591 at a predetermined interval in the vertical direction.

[0644] Furthermore, these can be configured such that a guide protrusion 561 and a guide hole 591a can overlap in the front-to-back direction. That is, a plurality of guide protrusions 561 and guide holes 591a are configured such that a guide protrusion 561 can be inserted into a guide hole 591a.

[0645] Each guide protrusion 561 may be provided in the form of a hook. The hook may include a main body portion 561a and a protrusion portion 561b. The main body portion 561a may be formed to protrude forward from the main panel portion 551.

[0646] At this time, the main body 561a can be formed to be elastically deformable in the vertical direction. In addition, the protrusion 561b can protrude from the main body 561a and can protrude in the direction opposite to the other hook adjacent in the vertical direction.

[0647] For example, the protrusion 561b of the upper hook in a pair of hooks can protrude upwards, and the protrusion 561b of the lower hook in a pair of hooks can protrude downwards.

[0648] The guide protrusion 561, configured as described above, can pass through the first joint portion 591 via the guide hole 591a and engage with the first joint portion 591. By utilizing the engagement between the guide protrusion 561 and the first joint portion 591 constructed in this manner, a preliminary engagement between the support panel 550 and the bracket 590 can be achieved.

[0649] The initial connection here can refer to the connection state in which the support panel 550 and the bracket 590 are detachably connected, and the connection position between the support panel 550 and the bracket 590 is guided.

[0650] Additionally, fastening holes 562 can be provided in the mating area 550c, and fastening holes 591b can be provided in the first mating portion 591. These fastening holes 562 and 591b are provided for using fastening members 565 to fasten the support panel 550 and the bracket 590. The fastening members 565 here can be provided in the form of screws, which are the same as or similar to the aforementioned fastening members 563.

[0651] The mating region 550c and the first mating portion 591 are aligned such that the fastening hole 562 of the mating region 550c overlaps with the fastening hole 591b of the first mating portion 591 in the front-back direction. In this state, the screw passes through the mating region 550c and the first mating portion 591 through these fastening holes 562 and 591b, thereby achieving the mating between the mating region 550c and the first mating portion 591.

[0652] The positional alignment between the support panel 550 and the bracket 590, which are configured to overlap in the front-to-back direction for fastening holes 562 in the mating area 550c and fastening holes 591b in the first mating portion 591, can be guided by the engagement between the guide protrusion 561 and the first mating portion 591.

[0653] That is, by inserting the guide protrusion 561 into the first joint 591, the positional alignment between the support panel 550 and the bracket 590 can be achieved, so that the fastening hole 562 of the joint area 550c and the fastening hole 591b of the first joint 591 can overlap in the front-back direction.

[0654] On the other hand, in this embodiment, the fastening holes 562 and 591b are arranged on the outer side in the vertical direction of the guide protrusion 561 as an example. This is a result of the design considering that the closer the screw fastening is to the upper and lower ends of the support panel 550 and the bracket 590, the more stable the connection between the support panel 550 and the bracket 590.

[0655] That is, by using screws to firmly fix the positions adjacent to the upper end of the support panel 550 and the bracket 590 and the positions adjacent to the lower end of the support panel 550 and the bracket 590, the support panel 550 and the bracket 590 can be firmly connected to each other, preventing the upper or lower end of the support panel 550 and the bracket 590 from shaking.

[0656] In addition, since the central portion of the support panel 550 and bracket 590, which are fastened without screws, is hooked together by the guide protrusion 561, the central portion of the support panel 550 and bracket 590 can also be kept from shaking.

[0657] The following will summarize the function and effect of the bonding structure between the bonding region 550c and the first bonding part 591.

[0658] The initial connection between the support panel 550 and the bracket 590 can be achieved by guiding the engagement between the protrusion 561 and the first joint 591. When the initial connection between the support panel 550 and the bracket 590 is achieved in the above manner, the support panel 550 and the bracket 590 can be aligned, thus placing them in a state suitable for using screws to connect them. Furthermore, when the initial connection between the support panel 550 and the bracket 590 is achieved, the support panel 550 and the bracket 590 can be temporarily fixed, allowing for easy screw tightening.

[0659] Furthermore, screws can be used to securely fix the upper ends of the support panel 550 and the bracket 590, as well as the lower ends of the support panel 550 and the bracket 590, while guide protrusions 561 can be used to join the support panel 550 and the bracket 590 in the central portion of the support panel 550 and the bracket 590 in the vertical direction.

[0660] As a result, the connection between the support panel 550 and the bracket 590 can be firmly achieved without wobbling, and the screw tightening operation that can be used for this connection becomes easier.

[0661] On the other hand, the second connecting portion 593 can be connected to the door body portion 300a, and more specifically, to the front side of the second door body portion 350a. For this purpose, a fastening hole 353a can be provided on the front side of the second door body portion 350a, and a fastening hole 593a can be provided on the second connecting portion 593. The purpose of providing these fastening holes 353a and 593a is to use the fastening member 563, described later, to fasten the door body portion 300a and the bracket 590.

[0662] The front side of the second door main body 350a and the second connecting part 593 are connected so that the fastening holes 353a on the front side of the second door main body 350a and the fastening holes 593a on the second connecting part 593 overlap in the front-back direction. In this state, the fastening member 563 can pass through the fastening holes 353a and 593a through the front side of the second door main body 350a and the second connecting part 593, thereby realizing the connection between the front side of the second door main body 350a and the second connecting part 593.

[0663] The fastening member 563 may be provided in the form of a screw. Specifically, the fastening member 563 may include a body portion 563a and a head 563b. The body portion 563a is formed in a generally cylindrical shape, and the outer peripheral surface of such a body portion 563a may be threaded. Furthermore, the head 563b may be formed to protrude from the end of the body portion 563a in the longitudinal direction toward the centrifugal direction of the body portion 563a.

[0664] According to this embodiment, a fastening member 563 can be used to achieve the connection between the second joint 593 of the bracket 590 and the front of the second door body 350a, as well as the connection between the front of the second door body 350a and the handle 305.

[0665] That is, the fastening member 563 can pass through the front of the second connecting part 593 and the second door body 350a and be inserted into the handle 305, thereby connecting the handle 305 and the second connecting part 593 to the front of the second door body 350a. In other words, the handle 305 and the second connecting part 593 can be connected to each other across the front of the second door body 350a.

[0666] For this purpose, the fastening member 563 can pass through the second joint 593 from the rear and through the front of the second door body 350a and be inserted into the handle 305, so that the head 563b is positioned behind the second joint 593.

[0667] If the connection between the bracket 590 and the door body 300a and the connection between the door body 300a and the handle 305 are achieved separately at different positions, then the connection between the bracket 590 and the door body 300a will inevitably be exposed to the outside of the door 300.

[0668] For example, if the fastening member 563 is used to connect the bracket 590 and the door body 300a from the front of the door 300, the head 563b of the fastening member 563 will inevitably protrude to the outside of the door 300.

[0669] Furthermore, if the fastening member 563 is used for connection from the rear of the bracket 590, the main body 563a of the fastening member 563 will inevitably be exposed to the outside of the door 300. Therefore, an additional structure must be added to the outside of the door 300 to cover the fastening member 563.

[0670] Furthermore, since the front of the second door body 350a and the thickness of the second joint 593 are not very thick, it is difficult to ensure the bonding strength between the door body 300a and the bracket 590. In addition, if the bonding between the bracket 590 and the door body 300a and the bonding between the door body 300a and the handle 305 are performed separately at different locations, the time required for the fastening work will also increase accordingly.

[0671] In view of these aspects, in this embodiment, a fastening structure is proposed that can combine the bracket 590, the door body 300a and the handle 305 in one fastening operation using a fastening member 563.

[0672] Therefore, the combination of the bracket 590, the door body 300a and the handle 305 can be achieved by inserting a portion of the fastening member 563, which protrudes outward from the door body 300a through the bracket 590 and the door body 300a, into the handle 305.

[0673] As a result, the connection between the bracket 590 and the door body 300a can be achieved without any part of the fastening member 563 protruding to the outside of the door 300. Furthermore, even if the front of the second door body 350a and the thickness of the second connection portion 593 are not very thick, the handle 305 can sufficiently ensure the insertion depth of the fastening member 563, thereby also sufficiently ensuring the connection strength between the door body 300a and the bracket 590.

[0674] Furthermore, since the bracket 590, the door body 300a, and the handle 305 can be combined simultaneously in a single fastening operation, the time required for the fastening operation can be reduced accordingly.

[0675] On the other hand, the fastening member 563 can connect the bracket 590 and the door body 300a while passing through the fastening hole 593a of the second joint 593 and the fastening hole 353a on the front of the second door body 350a.

[0676] At this time, the fastening hole 593a of the second joint 593 can be configured in a position that does not overlap with the first joint 591 in the front-back direction or in a position where the rear of the fastening hole 593a is not covered by the first joint 591. That is, the fastening hole 593a of the second joint 593 can be configured in a position that can be exposed to the outside of the first joint 591 when viewed from the rear.

[0677] In this embodiment, the second connecting portion 593 is shown as being shorter in the vertical direction than the first connecting portion 591 and longer in the horizontal direction than the first connecting portion 591. For example, the second connecting portion 593 of the bracket 590 disposed on the left side is formed to protrude further to the right than the first connecting portion 591, and the second connecting portion 593 of the bracket 590 disposed on the right side is formed to protrude further to the left than the first connecting portion 591.

[0678] The fastening hole 593a provided in the second joint 593 can be positioned to protrude further to the left and right than the first joint 591. That is, the fastening hole 593a of the second joint 593 of the bracket 590 on the left side can be positioned to protrude further to the right than the first joint 591. Furthermore, the fastening hole 593a of the second joint 593 of the bracket 590 on the right side can be positioned to protrude further to the left than the first joint 591.

[0679] This was designed to make fastening operations using fastening component 563 easier to perform.

[0680] That is, since the fastening using the fastening member 563 is achieved behind the bracket 590, it is not easy to perform the fastening operation if the fastening hole 593a provided in the second joint 593 is blocked by the first joint 591.

[0681] Taking these aspects into consideration, in this embodiment, the fastening hole 593a of the second joint 593 is positioned so that it can be exposed to the outside of the first joint 591 when viewed from the rear. Therefore, fastening operations using the fastening member 563 can be performed more easily without being obstructed by other structures such as the first joint 591.

[0682] Figures 29 to 31 This is a three-dimensional view of the back of the door, showing the assembly process of the front of the door.

[0683] The following is for reference Figures 26 to 31 This describes the assembly process of the front of the door.

[0684] Reference Figure 26 and Figure 29To assemble the front panel 350 of the door, the bracket 590 and the main body 300a can be joined first. The joining of the bracket 590 and the main body 300a can be performed in the following manner.

[0685] First, the handle 305 is positioned at the front of the front of the second door body 350a, and the bracket 590 is positioned at the rear of the front of the second door body 350a. At this time, the fastening hole formed inside the handle 305, the fastening hole 353a formed on the front of the second door body 350a, and the fastening hole 593a formed on the second joint portion 593 of the bracket 590 should overlap in the front-rear direction.

[0686] In this state, the fastening member 563 is fastened from the rear of the second joint 593 to the front of the second joint 593 and the second door body 350a. Thus, the fastening member 563 can pass through the rear of the second joint 593 and the front of the second door body 350a and be inserted into the handle 305.

[0687] As a result, the bracket 590, the door body 300a, and the handle 305 can be combined in one fastening operation using a fastening component 563.

[0688] In this embodiment, it is illustrated by providing two fastening positions for each bracket 590 using the fastening member 563. For example, in each second joint 593, a pair of fastening holes 593a can be spaced apart in the vertical direction, and on the front of the second door body 350a, the fastening holes 353a can also be respectively arranged at corresponding positions. Therefore, the connection between the handle 305, the door 300, and the bracket 590 can be completed by using four fastening operations using the fastening member 563.

[0689] Additionally, an insertion hole 593b can be formed between a pair of fastening holes 593a on the second joint portion 593. Furthermore, such an insertion hole 355a can also be formed on the front side of the second door body portion 350a.

[0690] Additionally, an insertion protrusion 305a may be provided in the handle 305. The insertion protrusion 305a may protrude rearward from the rear ends on both sides of the handle. Such an insertion protrusion 305a may be inserted into the insertion holes 355a and 593b and engage with the front of the second door body 350a and the second connecting portion 593.

[0691] By engaging the insertion protrusion 305a with the front surface of the second door body 350a and the second connecting portion 593 in this manner, the engagement position between the handle 305 and the front surface of the door 350 can be guided. That is, when the insertion protrusion 305a is inserted into the insertion holes 355a and 593b, the fastening holes of the handle 305, the front surface of the door 350, and the second connecting portion 593 can be aligned in a way that overlaps in the front-back direction.

[0692] As a result of this design, the operation of combining the handle 305, the door 300, and the bracket 590 can be made more accurate and easier.

[0693] As described above, after the handle 305, door 300, and bracket 590 are assembled, as... Figure 26 , Figure 27 as well as Figure 30 As shown, a preliminary connection can be made between the support panel 550 and the bracket 590. The preliminary connection between the support panel 550 and the bracket 590 can be achieved by the connection between the guide protrusion 561 and the first connection portion 591.

[0694] As a result, the support panel 550 and the bracket 590 are detachably coupled, and the positions between the support panel 550 and the bracket 590 can be aligned so that the fastening hole 562 of the support panel 550 and the fastening hole 591b of the first joint 591 can overlap in the front-back direction.

[0695] Then, as Figure 26 , Figure 27 as well as Figure 31 As shown, the open rear of the door body 300a is covered by a door back cover 350b. In this state, screws are tightened from the rear of the door back cover 350b to the front of the door back cover 350b.

[0696] Therefore, the door back cover 350b, the mating area 550c, and the first mating part 591 can be fastened with a single screw. That is, the mating between the door back cover 350b, the support panel 550, and the bracket 590 can be completed in one go using a single screw.

[0697] In this embodiment, it is illustrated by the example that each bracket 590 has two fastening positions for the screws. For instance, in each first joint 591, a pair of fastening holes 591b can be spaced apart in the vertical direction, and in the door back cover 350b and the support panel 550, fastening holes 562 can also be arranged in corresponding positions. Therefore, the connection between the door back cover 350b, the support panel 550, and the bracket 590 can be completed by using four tightening operations with the screws.

[0698] In summary, the connection between the handle 305, the door 300, and the bracket 590 requires only four tightening operations, and the connection between the door back cover 350b, the support panel 550, and the bracket 590 requires only four tightening operations. Therefore, the assembly of the front part of the door 350 requires only a very small number of tightening operations.

[0699] This significantly reduces the time required for assembling the door 300, and makes the assembly of the door 300 easier and faster.

[0700] [Temperature sensor configuration]

[0701] Figure 32 It is a schematic cross-sectional view showing the internal structure of a cooking appliance.

[0702] like Figure 30 and Figure 32 As shown, the cooking apparatus of this embodiment may include a temperature sensor 580. The temperature sensor 580 is configured to measure the temperature inside the cooking chamber 105. In this embodiment, the temperature sensor 580 is illustrated as a thermostat.

[0703] This temperature sensor 580 can be used to maintain the temperature of the cooking chamber 105 at a set temperature. Additionally, the temperature sensor 580 can be used to maintain the temperature of the cooking chamber 105 to prevent overheating inside the cooking chamber 105.

[0704] The temperature sensor 580 is disposed on the front face 350 of the door, and the height of the temperature sensor 580 can be determined to be between the bottom surface 110 of the housing 100 and the first heating element 400. Preferably, the temperature sensor 580 can be disposed closer to the first heating element 400 than the bottom surface 110 of the housing 100. That is, the temperature sensor 580 can be disposed at a height slightly upward inside the cooking chamber 105.

[0705] More preferably, the temperature sensor 580 may be disposed between the tray 200 and the first heating element 400. More preferably, the temperature sensor 580 may be disposed at a position closer to the first heating element 400 than the tray 200.

[0706] The configuration of the temperature sensor 580 as described above is designed with consideration of the temperature distribution inside the cooking chamber 105 and the possible interference between the temperature sensor 580 and the food being cooked inside the cooking chamber 105.

[0707] In the cooking apparatus, food can be cooked inside the cooking chamber 105. For this purpose, the food can be placed on the tray 200. That is, typically with the food placed on the tray 200, cooking can be performed by heating the interior of the cooking chamber 105 by at least one of the first heating unit 400 and the second heating unit 600.

[0708] As described above, with food placed on tray 200, the possibility of interference between the food and temperature sensor 580 cannot be ruled out. If interference occurs, the temperature measurement performed by temperature sensor 580 may be inaccurate, or errors may occur during the operation of temperature sensor 580. Therefore, a configuration of temperature sensor 580 that can avoid interference between food and temperature sensor 580 is needed.

[0709] Additionally, generally, the temperature inside the cooking chamber 105 tends to be higher closer to the top of the cooking chamber 105. This is because the heated air rises, and the first heating element 400, which heats the interior of the cooking chamber 105, is located at the top of the cooking chamber 105.

[0710] Of course, a second heating element 600 is also provided in the lower part of the cooking chamber 105 (see reference). Figure 32 However, unlike the first heating element 400 which generates direct heat, the second heating element 600 is not a direct heating device. Therefore, inside the cooking chamber 105, the temperature clearly tends to be higher closer to the top of the cooking chamber 105.

[0711] In this embodiment, the example shown is that the temperature sensor 580 is used to maintain the temperature of the cooking chamber 105 at a set temperature or to prevent overheating. In order for the temperature sensor 580 to perform such a function effectively, it may be more advantageous to configure the temperature sensor 580 in a location in the cooking chamber 105 where the temperature is relatively high, rather than the other way around.

[0712] Generally, the opposite of a lower-than-expected temperature can be considered to have a greater impact on food; therefore, it is preferable to measure the temperature at a location where the presented temperature is higher. This is especially true if the function of the temperature sensor 580 is to prevent overheating.

[0713] Additionally, due to the temperature measurement module 640 (reference) Figure 35 The temperature sensor 580 is positioned on one side near the lower part of the cooking chamber 105 to measure the temperature. Therefore, the temperature sensor 580 is preferably positioned at a distance from the temperature measurement module 640, rather than being positioned very close to the temperature measurement module 640.

[0714] Taking these aspects into consideration, in this embodiment, the temperature sensor 580 is made effective by positioning it at a height more towards the top inside the cooking chamber 105 to maintain the temperature of the cooking chamber 105 at a set temperature or to prevent overheating.

[0715] On the other hand, such as Figure 21 , Figure 22 , Figure 26 as well as Figure 31 As shown, the second region 550b can be configured on the outer side of the first region 550a in the lateral direction, and the temperature sensor 580 can be configured in the second region 550b.

[0716] As described above, a first control board 500 is disposed in the first region 550a, and various components related to the operating device 1000, such as the shaft 1100 and the encoder 1200, are disposed on the first control board 500. Thus, the first control board 500 is sized to occupy a considerable area on the support panel 550. Therefore, the first control board 500 occupies more than half of the area of ​​the support panel 550.

[0717] Furthermore, in this embodiment, the operating device 1000 is positioned at the top of the front panel 350 of the door. Therefore, in order to accommodate the various components related to the operating device 1000 on the first control board 500, the first control board 500 should also be positioned to occupy the top of the front panel 350 of the door.

[0718] Therefore, the top area of ​​the support panel 550 is inevitably occupied by the first control substrate 500. Furthermore, it is practically difficult to ensure space for mounting the temperature sensor 580, i.e., space for mounting the temperature sensor support 557, on the top of the first control substrate 500.

[0719] Considering these aspects, in this embodiment, the temperature sensor 580 can be disposed on one side of the first control substrate 500 in the lateral direction so that the temperature sensor 580 does not overlap with the first control substrate 500 in the front-back direction. That is, the temperature sensor 580 can be disposed at a position biased towards the top in the cooking chamber 105, and also disposed on one side biased towards the lateral direction. As an example, the temperature sensor 580 can be disposed adjacent to the upper corner of the door front face 350 formed as a quadrilateral.

[0720] Therefore, the temperature sensor 580 can be configured in a position that avoids interference with other components such as the first control board 500 and can still function effectively.

[0721] In addition, considering that food is usually placed in the center of the cooking chamber 105, since the temperature sensor 580 is positioned near the upper corner as described above, it can also provide the effect of greatly reducing the possibility of the temperature sensor 580 coming into contact with the food.

[0722] On the other hand, according to this embodiment, the cooking apparatus may also include a shielding plate 328. The shielding plate 328 may be disposed on the lower part of the top surface 310 of the door. Such a shielding plate 328 may be formed into a plate shape having a length extending along the length direction of the first heating section 400.

[0723] According to this embodiment, a pair of first heating elements 400 are disposed on the lower part of the top surface 310 of the door, and a pair of shielding plates 328 may also be disposed therecorrespondingly. Each shielding plate 328 may be disposed adjacent to the first heating elements 400 and guide the heat dissipation direction of the first heating elements 400.

[0724] For example, in a pair of first heating units 400, a shielding plate 328 disposed adjacent to the first heating unit 400 located near the front of the door 350 can be disposed between the front of the door 350 and the first heating unit 400. Furthermore, in a pair of first heating units 400, a shielding plate 328 disposed adjacent to the first heating unit 400 located at the opposite rear can be disposed between the back of the housing 100 and the first heating unit 400.

[0725] The shielding plate 328 configured as described above can guide the heat dissipation direction of the first heating element 400 to the central side of the cooking chamber 105. In particular, such a shielding plate 328 can prevent the heat of the first heating element 400 from dissipating to the front side of the door 350 or the back side of the housing 100 140.

[0726] The first heating element 400 is disposed near the front part 350 of the door or the back part 140 of the housing 100. Therefore, it can be considered that the front part 350 of the door and the back part 140 of the housing 100 are exposed to an environment that is easily heated by the first heating element 400.

[0727] However, since various electrical components are located inside the front panel 350 of the door and the rear side of the housing 100, it is not desirable to centrally heat this part.

[0728] Considering these aspects, in this embodiment, shielding plates 328 are respectively disposed between the front door portion 350 and the first heating portion 400, and between the back of the housing 100 and the first heating portion 400. The shielding plates 328 disposed as described above block the heat from the first heating portion 400 from dissipating to the front door portion 350 side or the back of the housing 100 side, thus helping to prevent electrical components from being damaged by heat.

[0729] Additionally, a shielding plate 328 located adjacent to the front face 350 of the door can be disposed between the temperature sensor 580 and the first heating element 400. Therefore, the temperature sensor 580 can be configured such that the temperature sensor 580 and the first heating element 400 are blocked by the shielding plate 328.

[0730] Therefore, the temperature sensor 580 can be disposed in a region that is not directly affected by the heat of the first heating element 400. That is, the temperature sensor 580 can be disposed in a region adjacent to the first heating element 400 but not directly affected by the heat of the first heating element 400.

[0731] Therefore, even if the temperature sensor 580 is positioned close to the first heating element 400, the temperature sensor 580 can provide a highly reliable measurement result that is close to the actual temperature inside the cooking chamber 105.

[0732] [Structure of the touch control unit]

[0733] Figure 33 It is shown Figure 1 A cross-sectional view of the structure of the touch operation unit shown.

[0734] Reference Figure 1 , Figure 13 as well as Figure 33 The cooking apparatus of this embodiment may further include a touch operation unit 1900. The touch operation unit 1900 may be disposed together with the operation device 1000 on the front of the door front portion 350. In this embodiment, it is illustrated that the touch operation unit 1900 is disposed adjacent to the operation device 1000 and on the side of the operation device 1000. The user can directly operate the touch operation unit 1900 together with the operation device 1000 to adjust the operation of the cooking apparatus.

[0735] As an example, the touch operation unit 1900 may include at least one of an operation switch for adjusting the on / off state of the first heating unit 400 and an operation switch for selecting the type and state of the object to be cooked.

[0736] The touch operation unit 1900 may include a substrate 1910 and a booster 1920.

[0737] The substrate 1910 can be disposed inside the front panel 350 of the door in a manner that is fixed to the support panel 550. For this purpose, the support panel 550 may also include a touch panel support 565.

[0738] The touch panel support 565 can be disposed in the second region 550b, that is, the region where the first control substrate 500 is not disposed. Such a touch panel support 565 supports the touch operation unit 1900, thereby the touch operation unit 1900 can be supported by the touch panel support 565 and disposed in the second region 550b.

[0739] The touch panel support portion 565 may include a protruding surface portion 565a, a protruding support surface portion 565b, and a protruding rib portion 565c.

[0740] The protruding face 565a can be formed to protrude forward from the main panel portion 551 and can form a plane parallel to the main panel portion 551.

[0741] Furthermore, the protruding support surface 565b can be formed to protrude forward from the protruding surface 565a, and can form a plane parallel to the main panel portion 551. Such a protruding support surface 565b can support the substrate 1910 at a position further forward than the main panel portion 551 and the protruding surface 565a.

[0742] As described above, since the substrate 1910 is supported by the protruding support surface 565b, the touch operation part 1900 can remain in close contact with the front of the second door body part 350a and be fixed inside the front of the door body part 350.

[0743] The protruding ribs 565c can be configured adjacent to the protruding support surface 565b. In the touch panel support portion 565, a pair of protruding ribs 565c can be configured with a predetermined interval across the protruding support surface 565b. In this embodiment, it is shown as an example that a pair of protruding ribs 565c are configured with a vertical distance across the protruding surface 565a.

[0744] Each protruding rib 565c can be formed to protrude forward from the protruding face 565a. For example, each protruding rib 565c can be formed to protrude forward to the same degree as the protruding supporting face 565b.

[0745] Each protruding rib 565c may have a fixing groove. A padding member 566 may be inserted into such a fixing groove. The padding member 566 can be fixed to the protruding rib 565c by being inserted into the fixing groove.

[0746] The padding member 566 can be disposed between the touch panel support portion 565 and the substrate 1910, and more specifically, between the protruding portion 565a and the substrate 1910. When inserted into the fixing groove, such a padding member 566 can be shaped to protrude further forward than the protruding rib 565c and the protruding support portion 565b. Furthermore, the padding member 566 can be provided in a form capable of elastic deformation.

[0747] The padding member 566 can be configured to overlap the substrate 1910 between the protruding surface 565a and the substrate 1910. Such a padding member 566 can apply a force to push the substrate 1910 forward to the substrate 1910, thereby allowing the touch operation part 1900 to more effectively adhere to the front of the second door body part 350a.

[0748] Additionally, the support panel 550 may also include outer support protrusions 567. In this embodiment, an example is shown where a plurality of outer support protrusions 567 are arranged on the outer side of the touch panel support portion 565 and the touch operation portion 1900.

[0749] Therefore, the outer support protrusions 567 can be respectively disposed on the outer side in the vertical direction and the outer side in the horizontal direction of the touch panel support portion 565 and the touch operation portion 1900. In addition, each outer support protrusion 567 can be formed to protrude forward from the main panel portion 551 of the support panel 550.

[0750] Each of the outer support protrusions 567 can protrude to make contact with the front of the second door body 350a. The outer support protrusions 567 formed in this way can support the front of the second door body 350a from the rear around the touch operation section 1900.

[0751] To operate the touch operation unit 1900, the user must press the front of the second door body 350a. If this operation is repeated, the front of the second door body 350a may deform due to repeated pressing. Since the outer support protrusion 567 supports the front of the second door body 350a around the touch operation unit 1900, deformation of the door 300 due to operation of the touch operation unit 1900 can be effectively prevented.

[0752] In addition, the outer support protrusion 567 supports the front of the second door main body 350a so that the front of the second door main body 350a can only be pressed in the front area of ​​the touch operation unit 1900, which can further help improve the operational reliability of the touch operation unit 1900.

[0753] As an example, the touch operation unit 1900 provided in the touch panel support portion 565 of the structure described above can be a metal touch switch using a capacitive sensor. At least one capacitor portion can be formed on the substrate 1910 of such a touch operation unit 1900.

[0754] The boost converter 1920 can be disposed in front of the substrate 1910. The boost converter 1920 can be disposed between the front side of the second door body 350a and the substrate 1910. Such the boost converter 1920 can be configured to be in close contact with the front side of the second door body 350a.

[0755] Function icons corresponding to the functions of the touch operation unit 1900 can be formed, either in relief or intaglio, in the area on the front of the second door main body 350a that is in close contact with the booster 1920. When the corresponding portion on the front of the second door main body 350a is pressed, the booster 1920 is pressed together with that portion and moves backward. As a result, the gap between the booster 1920 and the capacitor portion changes, and the touch on the touch operation unit 1900 can be identified by the resulting change in capacitance.

[0756] Only when the booster 1920 is well-fitted against the front of the second door body 350a can the touch recognition rate of the touch operation unit 1900 be improved. According to this embodiment, the padding member 566 provided on the protruding rib 565c can apply a force to push the substrate 1910 forward to the substrate 1910, thereby ensuring that the booster 1920 is effectively fitted against the front of the second door body 350a.

[0757] [Structure of the second heating element, receiving coil, and second control board]

[0758] Figure 34 This is an exploded perspective view showing the housing and the second heating part of an embodiment of the present invention separated and side by side. Figure 35 It is shown Figure 34 A top view of the second heating element shown. Additionally... Figure 36 It is Figure 34 An exploded perspective view showing the second heating element, receiving coil, and electromagnetic shielding plate separated from each other. Figure 37 It is shown Figure 34 A cross-sectional view showing the assembly of the second heating element, temperature sensor, receiving coil, and electromagnetic shielding plate. Additionally, Figure 38 It is shown Figure 34 The rear view of the second control board shown. Figure 39 It is shown in Figure 38 The rear view shown shows the second control board with a back cover on its back side.

[0759] Reference Figure 3 , Figure 34 as well as Figure 35 The second heating element 600 is disposed on the lower part of the tray 200. The second heating element 600 is located on the lower part of the bottom surface 110 of the housing 100 and is provided in a form that heats the tray 200 using a different heating method than the first heating element 400, such as an induction heating element. The induction heating element may be provided in the form of a working coil 610 disposed on the lower part of the bottom surface 110 of the housing 100, and can inductively heat the tray 200 from the lower part of the tray 200.

[0760] The working coil 610 includes a coil mounting base 611. In this embodiment, the coil mounting base 611 is shown as a quadrilateral shape that approximates the shape of the tray 200. This is a result of designing the size and shape of the working coil 610 to approximate the shape of the tray 200 so that the entire area of ​​the tray 200 can be heated using the working coil 610.

[0761] like Figures 35 to 37 As shown, a spiral groove is provided in the coil mounting base 611, which allows the coil 613 to be mounted with its center as a reference. The coil 613 is accommodated in this spiral groove and is tightly wound and fixed to the top of the coil mounting base 611. A coil connection wiring 615 is provided at the end of the coil 613, which connects to a coil control PCB for controlling the coil 613.

[0762] Additionally, the second heating unit 600 may also include a receiving coil 620. The receiving coil 620, configured to receive wirelessly transmitted power, is disposed at the lower part of the second heating unit 600. Furthermore, a base 180 is disposed at the lower part of the receiving coil 620. The base 180 is attached to the lower part of the bottom surface 110 of the housing 100 to support the working coil 610 and the receiving coil 620 from the lower part of the receiving coil 620, and forms the bottom surface appearance of the cooking device.

[0763] Similar to the working coil 610, the receiving coil 620 may include a coil mounting base 621 and a coil 623. Unlike the coil mounting base 611 of the working coil 610, the coil mounting base 621 of the receiving coil 620 is formed in a generally circular shape. This is a result of designing the shape of the receiving coil 620 to approximate the shape of the working coil disposed on the induction heating element of the cooktop.

[0764] According to this embodiment, the receiving coil 620 is configured to receive power from another cooking device, namely the induction heating part of the stove surface, which is separately provided from the cooking device of this embodiment.

[0765] For example, the cooking device in this embodiment can be used when placed on the stovetop, at which time the power required to operate the cooking device can be received from the induction heating element of the stovetop.

[0766] As an example, when the cooking device of this embodiment is placed on the stove surface and the working coil of the stove surface and the cooking device of this embodiment are started at the same time, the power supplied by the stove surface can be transmitted to the receiving coil 620.

[0767] At this time, the current is induced to the receiving coil 620 by the magnetic field that changes in the working coil on the stove surface due to electromagnetic induction, thereby allowing the power supplied by the stove surface to be transmitted to the receiving coil 620. In order to improve the power receiving efficiency of the receiving coil 620, it is preferable that the cooking device of this embodiment is placed on the stove surface, and the positions of the receiving coil 620 and the working coil of the induction heating part provided on the stove surface are arranged in a way that overlaps in the vertical direction.

[0768] Additionally, the induction heating unit may also include an electromagnetic shielding plate 630 disposed between the working coil 610 and the receiving coil 620. The electromagnetic shielding plate 630 may be in the form of a metal plate. This electromagnetic shielding plate 630, disposed between the working coil 610 and the receiving coil 620, serves to minimize the impact of EMI generated by the working coil 610 on the receiving coil 620, or vice versa.

[0769] The cooking appliance of this embodiment, including the receiving coil 620 as described above, can operate by receiving wireless power from the induction heating element of the cooktop. Such a cooking appliance offers a simple and clean appearance, eliminating the need for messy power cables, and can operate by receiving wireless power simply by placing the appliance on the cooktop, thereby further improving user satisfaction.

[0770] like Figures 34 to 38 As shown, the receiving coil 620 can be electrically connected to a second control board 700 disposed behind the working coil 610 and the receiving coil 620. Power wirelessly transmitted from the working coil of the cooktop to the receiving coil 620 is transmitted to the second control board 700 side, which is electrically connected to the receiving coil 620.

[0771] According to this embodiment, the internal space at the lower part of the bottom surface 110 of the housing 100 and the internal space at the rear side of the back surface 140 of the housing 100 are connected to each other. The working coil 610 of the induction heating part disposed at the lower part of the bottom surface 110 of the housing 100 and the second control board 700 disposed at the rear side of the back surface 140 of the housing 100 can be electrically connected to each other by a cable, which connects the working coil 610 and the second control board 700 to each other through the internal space at the lower part of the bottom surface 110 of the housing 100 and the internal space at the rear side of the back surface 140 of the housing 100.

[0772] The second control board 700 is provided with a power supply processing unit that supplies power required for the operation of the induction heating unit and the like in the second heating unit 600. The power supply processing unit is connected to the receiving coil 620 to receive power from the receiving coil 620, and processes the supplied power in a manner suitable for use in the second heating unit 600 and the like. Such a power supply processing unit may include a noise filter PCB, and the second control board 700 may also include a coil control PCB for controlling the operation of the working coil 610.

[0773] The function of the noise filter PCB is to remove noise from the power supply provided to the working coil 610, and the control coil PCB controls the operation of the working coil 610. Chips for controlling the operation of the working coil 610, such as IGBT chips, can be installed on the coil control PCB.

[0774] IGBT is a high-heat chip that requires temperature management. When the temperature of the IGBT rises excessively above a predetermined temperature, the operating coil 610 will be unable to be controlled.

[0775] Therefore, a second cooling fan 730 is provided on the second control board 700. The second cooling fan 730 may be a Schiele fan, which draws in air from the external space of the housing 100 and exhausts the drawn-in air to the IGBT side.

[0776] The second cooling fan 730 can be configured on the side of the IGBT and can draw in air from the rear side of the housing 100 and exhaust the drawn-in air toward the side of the IGBT.

[0777] Air flowing into the rear space of the housing 100 via the second cooling fan 730 first contacts and cools the IGBTs and the heat sink used to cool the IGBTs, and can be discharged to the outside after cooling the noise filter PCB section.

[0778] The second control board 700 and the second cooling fan 730 can be fixed to the back 140 of the housing 100 by fixing it to the back support panel 750.

[0779] like Figure 3 and Figure 38 As shown, the rear support panel 750 can be disposed at the rear of the housing 100. The rear support panel 750 can be fixed to the rear of the housing 100 by engaging with the rear side 140 of the housing 100. Such a rear support panel 750 may include a main panel portion 751 and a first protruding edge portion 755.

[0780] A support surface for supporting the second control substrate 700 can be formed in the main panel portion 751. In this embodiment, the main panel portion 751 is formed in a shape similar to the back surface 140 of the housing 100, for example, it is formed in a rectangular shape.

[0781] The main panel 751 may be made of a lightweight insulating material and may have sufficient strength to support the second control substrate 700 and the various electrical components disposed on the second control substrate 700.

[0782] The first protruding edge portion 755 is disposed on the edge of the main panel portion 751. The first protruding edge portion 755 may be formed to protrude rearward from the edge of the main panel portion 751. As a result, a space enclosed by the main panel portion 751 and the first protruding edge portion 755 can be formed behind the main panel portion 751. Furthermore, the second control board 700 and the second cooling fan 730 can be disposed in such a space.

[0783] The rear support panel 750 may include a first region 750a and a second region 750b. The first region 750a is the region where the second control substrate 700 is disposed, and the second region 750b is the region where the second control substrate 700 is not disposed. In this embodiment, the first region 750a and the second region 750b are arranged in a left-right direction as an example. For example, the first region 750a may be disposed on the left side, and the second region 750b may be disposed on the right side, with the first region 750a occupying most of the rear support panel 750.

[0784] The second cooling fan 730 can be configured in the second area 750b. Additionally, the power connection unit 735 and the communication module 740 can be configured in the second area 750b.

[0785] A power connection portion 735 is provided on the rear support panel 750 and can be configured in the second region 750b. Such a power connection portion 735 can be configured on the side of the second control board 700 and electrically connected to the second control board 700.

[0786] As an example, the power connection 735 can be provided in the form of an inlet power socket. Such a power connection 735 can be connected to an external power source via a plug that connects to a power cable that is connected to an external power source. The power processing unit of the second control board 700 can process the power supplied through the power connection 735 into a form suitable for use in the second heating unit 600, etc.

[0787] The power connection portion 735 can be disposed on the side of the second control board 700 and on the lower part of the second cooling fan 730. If the power connection portion 735 is disposed on the upper part of the second cooling fan 730, the power connection portion 735 and the power cable connected thereto are easily exposed to the outside.

[0788] In addition, since the power cable connected to the power connection part 735 is located at the top, the power cable is more likely to become an obstacle or cause the cooking equipment to tip over during use.

[0789] Considering these aspects, in this embodiment, the power connection portion 735 is positioned in a location that is as inconspicuous as possible, for example, at the lower corner of the back of the cooking appliance. This effectively suppresses any reduction in the aesthetics of the cooking appliance caused by the power connection portion 735 and the power cable connected thereto, or any safety issues caused by the power cable.

[0790] The communication module 740 may be a communication module that enables wireless communication between an external device (such as a smartphone) and the cooking device.

[0791] As an example, communication module 740 can be a short-range communication module. For instance, communication module 740 can be a communication module that supports low-power wireless communication methods, such as BLE (Bluetooth Low Energy). Furthermore, communication module 740 can include modules that support various short-range communication methods, such as Bluetooth communication modules and NFC communication modules.

[0792] As another example, communication module 740 can be a mobile communication module. For instance, communication module 740 may include modules that support wireless communication methods, such as LTE (long term evolution), Wi-Fi, etc.

[0793] The communication module 740 can be disposed on the side of the second control board 700. Alternatively, the communication module 740 can be disposed below the second cooling fan 730 and above the power connection portion 735. That is, the communication module 740 can be disposed on the side of the second control board 700 and can be disposed between the second cooling fan 730 and the power connection portion 735.

[0794] This configuration of the communication module 740 is designed so that the power connection part 735 is positioned at the bottom among the second cooling fan 730, the communication module 740 and the power connection part 735, and the communication module 740 is positioned so that the wiring length between the communication module 740 and the second control board 700 is minimized.

[0795] In addition, such as Figure 3 , Figure 51 as well as Figure 52 As shown, the cooking apparatus of this embodiment may further include a back cover 760. The back cover 760 may be disposed behind and combined with the back support panel 750. Such a back cover 760 may include a main cover portion 761 and a second protruding edge portion 765.

[0796] The main cover portion 761 can be formed into a plane parallel to the rear support panel 750, and more specifically, a plane parallel to the main panel portion 751. In this embodiment, the main cover portion 761 is shown to be formed into a shape similar to the main panel portion 751, for example, a rectangle. Such a main cover portion 761 can be made of a lightweight insulating material.

[0797] The main cover 761 and the back cover 760 including the main cover 761 can be disposed between the back of the housing 170 and the second control board 700. The back cover 760 disposed as described above can be provided by an insulating structure that insulates the metal housing 170 and the second control board 700.

[0798] Additionally, a ventilation hole 762 may be provided in the back cover 760. The ventilation hole 762 may be formed to extend through the main cover 761 in the front-to-back direction. Such a ventilation hole 762 can form a channel on the main cover 761 for air to enter and exit.

[0799] The ventilation opening 762 can be configured to be spaced a predetermined distance from the second cooling fan 730. For example, if the second cooling fan 730 is located on the right side of the back of the cooking appliance, the ventilation opening 762 can be located on the left side.

[0800] This is to prevent the air expelled from the second cooling fan 730 from leaking prematurely to the rear of the back cover 760.

[0801] Additionally, a fan mounting hole 763 may be provided in the back cover 760. The fan mounting hole 763 may form a channel that allows a portion of the second cooling fan 730, which is disposed between the back support panel 750 and the back cover 760, to protrude to the rear of the back cover 760. Such a fan mounting hole 763 is formed to extend through the main cover portion 761 in the front-rear direction, and may be formed in a shape corresponding to the shape of the second cooling fan 730.

[0802] Since most of the second cooling fan 730, especially the portion exposed to the outside, is made of insulating material, the possibility of electrical problems occurring is very low, even if a portion of such a second cooling fan 730 is exposed behind the back cover 760 or in contact with the housing 170.

[0803] However, among the various components provided on the rear support panel 750, the component that protrudes the most rearward is likely the second cooling fan 730. Therefore, as described above, if a portion of the second cooling fan 730 can protrude rearward from the rear cover 760, then correspondingly, the rear cover 760 can be provided on the back of the cooking appliance with less protrusion to the rear.

[0804] That is, the dimensions of the cooking equipment in the front-to-back direction have room to be reduced accordingly. In addition, the insertion and connection between the second cooling fan 730 and the back cover 760 can guide the connection position between the back support panel 750 and the back cover 760, thereby making the installation of the back cover 760 easier.

[0805] Additionally, a cutting portion 764 may be provided in the back cover 760. The cutting portion 764 may be formed in the form of a portion of the main cover 761 being cut off. Such a cutting portion 764 may form a channel on the back cover 760 for connecting the power connection portion 735 and the housing 170.

[0806] The second protruding edge portion 765 can be disposed on the edge of the main cover portion 761. The second protruding edge portion 765 can be formed to protrude rearward from the edge of the main cover portion 761. Such a second protruding edge portion 765 can be engaged with the first protruding edge portion 755 of the rear support panel 750. Through their engagement, the rear cover 760 and the rear support panel 750 can be engaged to form a predetermined receiving space between the rear cover 760 and the rear support panel 750.

[0807] As an example, a hook 756 may be provided in either the first protruding edge portion 755 or the second protruding edge portion 765, and a hook groove for engaging with the hook 756 may be provided in the other of the first protruding edge portion 755 and the second protruding edge portion 765.

[0808] A through hole 171 extending in the front-rear direction can be formed on the back side of the second control base plate 700 and the housing 170. Furthermore, an intake / exhaust grille 175 can be disposed in such a through hole 171.

[0809] The through hole 171 can form a channel for allowing external air to flow into the second control board 700 side through the housing 170 or for allowing air around the second control board 700 to be discharged to the outside through the housing 170.

[0810] The intake / exhaust grille 175 allows air to flow in or out through the through-hole 171 and can prevent external foreign objects from penetrating through the through-hole 171. For example, the intake / exhaust grille 175 can be formed in a shape that includes a louver structure.

[0811] On the other hand, such as Figures 34 to 37 As shown, the second heating unit 600 in this embodiment may further include a temperature measurement module 640. The purpose of providing the temperature measurement module 640 is to measure the temperature of the tray or the temperature inside the cooking chamber 105 on which the tray is disposed.

[0812] The temperature measurement module 640 can be configured to be located in the center of the working coil 610. Specifically, the temperature measurement module 640 can be configured on a portion of the coil mounting base 611 where the coil 613 is not located, for example, it can be configured in the central portion of the coil mounting base 611.

[0813] Such a temperature measurement module 640 can be inserted into the working coil 610 through a through hole formed in the central portion of the coil mounting base 611. Furthermore, the temperature measurement module 640 configured as described above may include a temperature sensor such as a thermistor and may be configured on the lower part of the bottom surface 110 of the housing 100 to measure the temperature of the tray or the temperature inside the cooking chamber 105 on which the tray is configured.

[0814] [Arrangement relationship of hinge assembly, second heating element, second control board, viewing window, first heating element, operating device, and first control board]

[0815] Reference Figure 3 , Figures 34 to 39 The hinge assembly 800, the second heating part 600, and the second control board 700 are disposed in the housing 100.

[0816] A cooking chamber 105 is formed inside the housing 100, and a tray 200 can be disposed in the cooking chamber 105. A second heating element 600 for heating the tray 200 is disposed at the lower part of the housing 100. Furthermore, hinge assemblies 800 for rotatably supporting the door 300 are disposed on both sides of the housing 100.

[0817] Hinges assemblies 800 are disposed on both sides of housing 100 to stably support door 300 on both sides of door 300.

[0818] Because the top and front surfaces of the housing 100 are open, and the second heating element 600 is provided at the lower part of the housing 100, the hinge assembly 800 can only be disposed on the rear or side surfaces of the housing 100. Disposing the hinge assembly 800 on the side surfaces of the housing 100 is advantageous in many respects for the reasons mentioned above.

[0819] The receiving coil 620 is disposed at the lower part of the housing 100, and more specifically, at the lower part of the second heating part 600. The receiving coil 620 should be disposed closest to the object for wireless power transmission, such as the working coil of the cooktop, therefore the receiving coil 620 should be disposed at the lower part of the housing 100.

[0820] As described above, when the receiving coil 620 and the working coil 610 of the second heating unit 600 are disposed together in the lower part of the housing 100, the EMI of the working coil 610 or the receiving coil 620 may affect each other. Taking these aspects into consideration, an electromagnetic shielding plate 630 may be disposed between the working coil 610 and the receiving coil 620.

[0821] The second control board 700, being a configuration closely related to the power reception via the receiving coil 620 and the operation of the working coil 610, is preferably positioned adjacent to the receiving coil 620 and the working coil 610.

[0822] The second heating element 600 and the receiving coil 620 are arranged at the lower part of the housing 100, and the hinge assembly 800 is arranged on both sides of the housing 100. Therefore, it can be considered that the most suitable position for arranging the second control board 700 is the rear.

[0823] Taking these aspects into consideration, the second control board 700 is disposed in the space behind the rear side 140 of the housing 100. The second control board 700 disposed as described above can be configured very close to the working coil 610 and the receiving coil 620, thereby making the wiring connecting the second control board 700 to the working coil 610 and the receiving coil 620 simple to construct.

[0824] Furthermore, as described above, the second control board 700, located at the rear of the housing 100, is also close to each hinge assembly 800. Therefore, when constructing the wiring connecting the various components of the door 300 and the second control board 700, these wirings can be easily hidden inside the hinge assembly 800, thus having the advantage of being able to construct the wiring neatly and simply without easily exposing the wiring to the outside.

[0825] As described above, the second heating element 600 and the receiving coil 620 are disposed at the lower part of the housing 100, the hinge assembly 800 is disposed at both sides of the housing 100, and the second control board 700 is disposed at the rear side of the housing 100. This configuration is more suitable for the housing 100 than a configuration disposed at the door 300, and each component is positioned optimally to achieve its best function. This configuration offers high structural stability, allows for neat and concise wiring, and effectively prevents interference between components.

[0826] On the other hand, refer to Figure 3 , Figure 5 as well as Figure 32 The door 300 includes a viewing window W, a first heating element 400, an operating device 1000, and a first control board 500. These components are functionally more suitable for placement in the door 300 than in the housing 100. Considering that some other components are already placed in the housing 100 and it is difficult to place other components, the placement of these components is more suitable for the door 300 side than for the housing 100.

[0827] The viewing window W is positioned at the top of the cooking appliance. Generally, considering the characteristics of cooking appliances provided in the form of mini ovens for use at a position below the user's line of sight, it is preferable to position the viewing window W at the top of the cooking appliance compared to positioning it at the front.

[0828] Such a viewing window W is disposed on the top surface of the door 300, more specifically, on the top surface 310 of the door. At this time, the larger the size of the viewing window W, the better it is to ensure a view of the interior of the cooking chamber 105, but it is preferable to limit the size of the viewing window W to a size that can ensure the space required to install the first heating element 400 and the cable mounting parts 340, 345 in the top surface 310 of the door.

[0829] The first heating element 400 is disposed on the top surface of the door 310 in the same manner as the viewing window W. This is a result of the design that places the first heating element 400 on the upper part opposite to the second heating element 600 across the tray 200. That is, the first heating element 400 is disposed on the top surface of the door 310, above the tray 200.

[0830] As described above, the first heating element 400, which is provided together with the viewing window W on the top surface 310 of the door, should be positioned in a location that is not exposed through the viewing window W when viewed from above. If the first heating element 400 is positioned in an area exposed through the viewing window W, it will not only be unsightly, but it will also cause problems in ensuring a clear view through the viewing window W, and may also lead to overheating of the portion of the viewing window W.

[0831] Furthermore, given that the shape of the front part 350 of the door is a rectangle with a length greater than its length in the front-back direction, the first heating part 400 should be positioned on the outer front and outer rear sides of the viewing window W in order to increase the length of the first heating part 400 accordingly. As the length of the first heating part 400 increases, the heat output of the first heating part 400 can be expected to increase.

[0832] Taking these aspects into consideration, the first heating element 400 is respectively arranged on the front outer side and the rear outer side of the viewing window W, thereby helping to ensure functional advantages such as maintaining aesthetics, ensuring a clear field of vision, suppressing the temperature rise of the viewing window W, and improving the heat output of the first heating element 400.

[0833] As described above, with the viewing window W and the first heating element 400 disposed on the top surface of the door 310, most of the area of ​​the top surface of the door 310 is occupied by the viewing window W and the first heating element 400. Furthermore, the operating device 1000 and the first control board 500 are disposed on the front surface of the door 350 instead of the top surface of the door 310.

[0834] Given that a large portion of the top surface of the door 310 is occupied by the viewing window W and the first heating element 400, it is difficult to ensure sufficient space for the operating device 1000 within the top surface of the door 310. Furthermore, if the operating device 1000 is positioned on the top surface of the door 310, there is a risk that it could collide with an obstacle located above the cooking equipment during the opening of the door 300, potentially damaging the operating device 1000. This risk is further increased if the operating device 1000 protrudes from the door 300.

[0835] Furthermore, the temperature of the top surface 310 of the door, where the first heating element 400 is located, is more likely to be higher than that of the front surface 350 of the door. Since the operating device 1000 is configured to be held and operated by a user, when such an operating device 1000 is located on the top surface 310 of the door, the likelihood of the user coming into contact with the hotter portion of the top surface 310 during operation increases. In other words, if the operating device 1000 is located on the top surface 310 of the door, the risk of burns or other injuries to the user may increase during operation.

[0836] Taking these factors into consideration, the operating device 1000 is located on the front of the door 350 instead of the top of the door 310. Because the operating device 1000 is located on the front of the door 350, the user can safely and conveniently adjust the operation of the cooking device from the front of the cooking device.

[0837] In addition to the operating device 1000, a first control board 500 is also disposed on the front face 350 of the door. The first control board 500 is provided with various components and circuits related to receiving operating signals input through the operating device 1000 and generating control signals for controlling the operation of the first heating unit 400 and the second heating unit 600. Therefore, the first control board 500 especially needs to be electrically connected to the operating device 1000.

[0838] According to this embodiment, the first control board 500 is disposed on the front face of the door 350 in the same manner as the operating device 1000, and is positioned very close to the operating device 1000. Therefore, the connection between the operating device 1000 and the first control board 500 can be configured such that the operating device 1000 is directly connected to the first control board 500, thus providing a very simple and stable connection structure between the operating device 1000 and the first control board 500.

[0839] Furthermore, since the first control board 500 is disposed on the front part 350 of the door, rather than on the top part 310 of the door where the first heating part 400, which serves as a heating element, is located, the first control board 500 can be positioned to a certain extent away from the heat generated by the first heating part 400. Therefore, the impact of the heat generated during the operation of the first heating part 400 on the first control board 500 can be reduced accordingly, thereby further improving the stability and operational reliability of the cooking equipment.

[0840] [Structure of the door frame]

[0841] Figure 42 It is Figure 41 The diagram shows the door frame separated and presented in three dimensions. Figure 43 This is a cross-sectional perspective view showing the assembled state of the door frame, the first heating element, and the protective grille. Additionally, Figure 44 This is a bottom view showing the assembled state of the door frame, the first heating element, and the protective grille. Additionally, Figure 45 It is along Figure 40 A sectional view taken along the line “XXXXV-XXXXV”. Figure 46 It is along Figure 40 A sectional view taken along the line “XXXXVI-XXXXVI”. Additionally, Figure 47 This is a perspective view showing the connection structure between the door frame and the hinge. Figure 48 This is a cross-sectional view showing the connection structure between the door frame and the hinge section. Figure 49 It is a cross-sectional view showing the door frame, hinges, and the connection structure between the door.

[0842] exist Figure 43 The diagrams of the glass and reflector are omitted in the text. Figures 45 to 48 The illustration of glass is omitted in the text.

[0843] Reference Figures 40 to 43 The door frame 320 covers the lower part of the top surface 310 of the door and is integrated with the door 300. Such a door frame 320 can support the first heating element 400 and is integrated with the door 300. Furthermore, the first heating element 400 integrated with the door frame 320 can remain positioned on the lower part of the door 300, more specifically, on the lower part of the top surface 310 of the door.

[0844] The door frame 320 may include a joint 321 and a heater mounting portion 325. The heater mounting portion 325 may be configured to protrude from the joint 321, and the first heating portion 400 may be coupled to such a heater mounting portion 325.

[0845] The joint 321 can be joined to the top surface 310 of the door, and the heater mounting part 325 is supported on the top surface 310 of the door. Such a joint 321 can be provided in the form of a frame with an "opening" shape and a through hole formed inside.

[0846] A mounting surface 322 may be formed on the inner side of the joint 321 adjacent to the through hole. The mounting surface 322 is a recessed plane with a height lower than the top surface of the joint 321, and the periphery of each edge of the glass 335 may be mounted on the mounting surface 322.

[0847] As described above, the glass 335 mounted on the mounting surface 322 covers the through hole from the top and can be disposed on the upper part of the heater mounting portion 325 and the first heating portion 400 disposed on the heater mounting portion 325. At this time, the mounting surface 322 forms a plane with a height lower than the top surface of the joint portion 321, and the height of this plane below the joint portion 321 can be approximately corresponding to the thickness of the glass 335. Therefore, the glass 335 can be disposed on the door frame 320 in a position where it does not protrude upwards from the top surface of the joint portion 321.

[0848] The mounting surface 322 can be disposed on both sides of the through hole in the left-right direction. Alternatively, the mounting surface 322 can also be disposed on one side or the other side of the through hole in the front-back direction. In this embodiment, the mounting surface 322 is shown as being disposed on both sides of the through hole in the left-right direction and on both sides in the front-back direction. Thus, the four edges of the glass 335 are supported by the mounting surface 322 and can be stably mounted on the door frame 320.

[0849] Furthermore, since the left-right movement of the glass 335 is constrained by the inner side of the joint 321 surrounding the mounting surface 322, the left-right setting position of the glass 335 can be guided, and the left-right swaying of the glass 335 can be suppressed, and the setting of the glass 335 can be stably achieved.

[0850] On the other hand, the first heating part 400 may include a heating element 410, a first connecting end 420 and a second connecting end 430.

[0851] The heating element 410 corresponds to the portion that dissipates heat from the first heating section 400, which is provided in the form of an electric heater. Such a heating element 410 can be formed into a rod shape having a predetermined length.

[0852] A first connecting end 420 is provided at one end of the heating element 410 along its length, and a second connecting end 430 is provided at the other end of the heating element 410 along its length, which is the opposite side.

[0853] At least one of the first connecting end 420 and the second connecting end 430 includes a cylindrical portion 421 and a key-shaped portion 425. In this embodiment, it is shown as an example where both the first connecting end 420 and the second connecting end 430 include a cylindrical portion 421 and a key-shaped portion 425.

[0854] The cylindrical portion 421 is disposed at the end of the heating element 410 in the longitudinal direction. Such a cylindrical portion 421 can be formed as a cylindrical shape with a circular bottom surface disposed at the outermost end of the first heating element 410.

[0855] The key-shaped portion 425 is disposed between the heating element 410 and the cylindrical portion 421. That is, with the heating element 410 as the center, the key-shaped portion 425 is disposed at both ends in the longitudinal direction, and the cylindrical portion 421 is disposed at the outermost end in the longitudinal direction.

[0856] The key-shaped portion 425 can be formed into a flat hexahedral shape, with a thickness thinner than the diameter of the cylindrical portion 421 and a width longer than the diameter of the cylindrical portion 421. For example, a pair of quadrilateral faces 426 (hereinafter referred to as "first faces") parallel to the width direction of the key-shaped portion 425 can be spaced apart in the thickness direction of the key-shaped portion 425 to form the top and bottom surfaces of the key-shaped portion 425. In addition, two pairs of quadrilateral faces 427 (hereinafter referred to as "second faces") parallel to the thickness direction of the key-shaped portion 425 can be arranged between the pair of first faces 426 to form the four sides of the key-shaped portion 425.

[0857] At this time, the first surface 426 can be formed as a quadrilateral surface with a side longer than the diameter of the cylindrical portion 421, and the second surface 427 can be formed as a quadrilateral surface with a side shorter than the diameter of the cylindrical portion 421.

[0858] Therefore, when the first connecting end 420 or the second connecting end 430 is viewed along the length direction of the first heating part 410, in most areas, the cylindrical part 421 protrudes further outward in the diameter direction of the cylindrical part 421 than the key-shaped part 425, and only in a portion of the area can the key-shaped part 425 protrude further outward in the diameter direction of the cylindrical part 421 than the cylindrical part 421.

[0859] A heater mounting portion 325 is provided to fix the first connecting end 420 and the second connecting end 430, which are provided in the manner described above. Such a heater mounting portion 325 may include a first connecting end fixing portion 326 for fixing the first connecting end 420 and a second connecting end fixing portion 327 for fixing the second connecting end 430.

[0860] At least one of the first connecting end fixing part 326 and the second connecting end fixing part 327 may include a cover a and a support wall b. In this embodiment, it is shown that both the first connecting end fixing part 326 and the second connecting end fixing part 327 include a cover a and a support wall b.

[0861] The cover a is provided in a form that surrounds the periphery of the connecting end from the periphery outward. Such a cover a can be formed as a curved shape that surrounds the lower part and sides of the connecting end, and can be formed so that its length corresponds to the length of each connecting end, or is slightly larger than the length of the connecting end.

[0862] In this embodiment, the cover a is shown as being formed in a "U" shape. Such a cover a can be formed around the periphery of the support wall b and around the lower and side portions of the support wall b. Furthermore, the top of the cover a can be open.

[0863] Additionally, the heater mounting portion 325 may also include a first lateral support portion 323. The first lateral support portion 323 may be disposed on one side further away from the center in the front-rear direction of the cooking chamber than the first heating portion 400, and may connect the first connecting end fixing portion 326 and the second connecting end fixing portion 327. Such a first lateral support portion 323 may be formed as a plate having a length extending along the length direction of the first heating portion 400.

[0864] Additionally, the heater mounting portion 325 may also include a second lateral support portion 324. The second lateral support portion 324 is disposed on one side closer to the center in the front-rear direction of the cooking chamber than the first heating portion 400, and can connect the first connecting end fixing portion 326 and the second connecting end fixing portion 327. In other words, the second lateral support portion 324 can be configured to face the first lateral support portion 323 through the cover a, and connect the first connecting end fixing portion 326 and the second connecting end fixing portion 327.

[0865] Such a second transverse support 324 is similar to the first transverse support 323 and can be formed as a plate having a length extending along the length direction of the first heating part 400.

[0866] According to this embodiment, the first connecting end fixing portion 326 and the second connecting end fixing portion 327 are respectively disposed at both ends in the longitudinal direction of the first heating portion 400. Furthermore, the first lateral support portion 323 is disposed on a side further away from the center in the longitudinal direction of the cooking chamber than the first heating portion 400. And the second lateral support portion 324 is disposed on a side closer to the center in the longitudinal direction of the cooking chamber than the first heating portion 400.

[0867] In addition, the cover a is respectively disposed in the first connecting end fixing part 326 and the second connecting end fixing part 327, and each cover a can be connected to the end of the first transverse support part 323 and the second transverse support part 324 in the length direction.

[0868] That is, the upper side of each cover a can be connected to the first transverse support 323 and the second transverse support 324 respectively.

[0869] A support wall b is disposed in the space surrounded by the cover a. This support wall b can be formed in a shape that protrudes from the cover a into the space. The support wall b formed in the above manner can divide the space surrounded by the cover a into an inner space and an outer space along the length direction of the first heating part 400. Furthermore, a connecting end can be inserted into and joined to this support wall b.

[0870] A mounting groove c can be formed in the support wall b.

[0871] The mounting groove c can be recessed into the support wall b. The inlet of such mounting groove c can be open upwards. By inserting the cylindrical part 421 into such mounting groove c, the connecting end can be inserted and engaged with the support wall b.

[0872] Additionally, the connecting end may include an extension 422. The extension 422 can be formed by extending the cylindrical portion 421 toward the key-shaped portion 425. This extension 422 is formed to protrude outward from the first surface 426 of the key-shaped portion 425 in the thickness direction, forming a step 423 between the extension 422 and the surface parallel to the width direction of the key-shaped portion 425, i.e., the first surface 426. According to the extension 422 formed in the above manner, an overlapping area of ​​the extension 422 and the key-shaped portion 425 is formed in a portion of the key-shaped portion 425 adjacent to the cylindrical portion 421.

[0873] The shape presented in this area is such that the extension 422 protrudes further in the thickness direction of the key-shaped portion 425 than the first surface 426 of the key-shaped portion 425, and the second surface 427 of the key-shaped portion 425 protrudes further in the width direction of the key-shaped portion 425 than the extension 422.

[0874] By forming the extension 422 in the manner described above, the strength of the joint between the cylindrical portion 421 and the key-shaped portion 425 can be further enhanced. If the extension 422 were not present, the joint between the cylindrical portion 421 and the key-shaped portion 425 would only be defined by the side end of the key-shaped portion 425. However, since the extension 422 is formed at the connecting end, the joint between the cylindrical portion 421 and the key-shaped portion 425 can be extended to the overlapping position of the extension 422 and the key-shaped portion 425, thus further enhancing the strength of the joint between the cylindrical portion 421 and the key-shaped portion 425.

[0875] On the other hand, the heater mounting portion 325 may also include a connection end support member 329. The connection end support member 329 can apply pressure to the connection end disposed in the mounting groove c in a direction that is in close contact with the support wall b, and fix the connection end to the support wall b. Such a connection end support member 329 may include a helical spring 329a disposed on the upper part of the mounting groove c and the support wall b.

[0876] The helical spring 329a can be positioned on the upper part of the mounting groove c along the direction spanning the inlet of the mounting groove c. The helical spring configured in this way can be positioned to block the inlet of the mounting groove c from the connecting end.

[0877] The first connecting portion 329b can be provided at one end along the length of the helical spring 329a. Furthermore, the second connecting portion 329c can be provided at the other end along the length of the helical spring 329a.

[0878] Furthermore, the first spring coupling part j and the second spring coupling part k can be disposed on the upper part of the support wall b. The first spring coupling part j and the second spring coupling part k are disposed on the upper part of the support wall b and can be configured to be separated from each other by a predetermined interval through the mounting groove c.

[0879] The first connecting part 329b can be connected to the first spring connecting part j, and the second connecting part 329c can be connected to the second spring connecting part k.

[0880] In this embodiment, the first joint portion 329b and the second joint portion 329c are respectively formed into hollow rings that are formed in the vertical direction, as an example.

[0881] In addition, either the first spring joint j or the second spring joint k can be configured as a protrusion protruding upwards from the support wall b, and the other of the first spring joint j and the second spring joint k can be configured as having a fastening hole extending in the vertical direction inside the support wall b.

[0882] In this embodiment, the first spring coupling part j is configured as a protrusion protruding towards the top of the support wall b, and the second spring coupling part k is configured to have a fastening hole formed inside the support wall b.

[0883] Therefore, by inserting the first connecting part 329b and the first spring connecting part j together, one side of the connecting end support member 329 along its length can be connected to the support wall b. Furthermore, by fastening the second connecting part 329c and the second spring connecting part k with screws, the other side of the connecting end support member 329 along its length can be connected to the support wall b.

[0884] The helical spring configured as described above can maintain a state where the connecting end is pressed downwards from the top. Therefore, the connecting end can be elastically supported inside the mounting groove c by the helical spring, that is, elastically supported by the connecting end support member 329.

[0885] By utilizing the connection end support structure formed in the above manner, the possibility of damage to the first heating element 400 can be significantly reduced. According to the connection end support structure, when an impact is applied to the first heating element 400 during the opening and closing of the door 300, or when an impact applied to the door 300 is transmitted to the first heating element 400, the impact on the first heating element 400 can be greatly reduced.

[0886] If the first heating element 400 is firmly fixed inside the mounting groove c and cannot move at all, when the first heating element 400 is subjected to an impact, the first heating element 400 will inevitably be affected by all the impacts, thereby inevitably increasing the possibility of damage to the first heating element 400.

[0887] In contrast, in this embodiment, the first heating element 400 is elastically supported by the connecting end support member 329. Therefore, when the first heating element 400 is impacted, it can move to a certain extent within the mounting groove c, thereby mitigating the impact to some extent, before returning to its original state, and then stably maintaining that state thereafter.

[0888] That is, in this embodiment, the first heating part 400 can be elastically supported by the connecting end support member 329, can be stably mounted on the heater mounting part 325, and can effectively suppress the first heating part 400 from being damaged by impact.

[0889] In addition, in the connection end support structure described above, the installation of the first heating part 400 can be completed with only the following simple operation: with one side of the connection end support member 329 hooked and fixed in the first spring coupling part j, the other side of the connection end support member 329 in the length direction is tightened with screws.

[0890] In summary, by utilizing the connection end support structure using the connection end support member 329, not only can the effects related to the stable installation of the first heating part 400 and the suppression of damage to the first heating part 400 be obtained, but the convenience of the installation operation of the first heating part 400 can also be improved.

[0891] On the other hand, the first connecting end fixing part 326 and the second connecting end fixing part 327 may each include an outer wall f. The outer walls f are respectively disposed on the outer side of the support wall b in the longitudinal direction of the heating element 410, and can be connected to the inner side of the connecting part 321. Such outer walls f form the outermost outer walls of the first connecting end fixing part 326 and the second connecting end fixing part 327 in the longitudinal direction of the heating element 410.

[0892] The first connecting end fixing part 326 and the second connecting end fixing part 327 are respectively formed with a space surrounded by a cover a, a support wall b and an outer wall f. This space is a space that surrounds the side and the bottom part by the cover a, the support wall b and the outer wall f, and at least a portion of the cylindrical part 421 of the fixing end of the first connecting end fixing part 326 or the second connecting end fixing part 327 is inserted into such a space.

[0893] Within the space, the cylindrical portion 421 can be connected to a cable. The cable connected to the cylindrical portion 421 can be from the first control board 500 (see reference 500). Figure 7 The signal cable that generates the control signal is transmitted to the first heating unit 400, and it can also be a power cable that supplies power to the first heating unit 400, or both a signal cable and a power cable.

[0894] like Figure 7 As shown, signal cables and power cables can be installed in cable mounting portions 340 and 345 provided in the top part of the door 310. Furthermore, the connection between the top part of the door 310 and the door frame 320 is configured such that the connection portion 321 covers the portion where the cable mounting portions 340 and 345 are arranged.

[0895] A plurality of fastening protrusions 341 and 346 are provided in the cable mounting portions 340 and 345, and a plurality of fastening holes 320a are correspondingly arranged in the door frame 320. After aligning the positions of the top surface 310 of the door and the door frame 320 so that the positions of the fastening holes 320a and the fastening protrusions 341 and 346 are consistent, the portions having the fastening holes 320a and the fastening protrusions 341 and 346 are fastened using fastening members, thereby achieving a connection between the top surface 310 of the door and the door frame 320. At this time, the portions having the cable mounting portions 340 and 345 are covered by the joint portion 321.

[0896] Glass panes 330 and 335 do not cover the portions where cable mounting portions 340 and 345 are located, but the first heating portion 400 and the heater mounting portion 325 are located in the lower part of the area covered by glass pane 335. Therefore, in order to connect the cable provided in the cable mounting portions 340 and 345 to the connection end, such as... Figures 53 to 56 As shown, a channel must be formed between the area of ​​the joint 321 not covered by glass 335 and the area of ​​the heater mounting portion 325 covered by glass 335.

[0897] Considering these aspects, in this embodiment, a groove g is provided at the connection between the outer wall f and the joint 321. The groove g forms a surface at the connection between the outer wall f and the joint 321 that is recessed from the top surface of the joint 321, and more specifically, forms a surface that is recessed from the mounting surface 322 of the joint 321. The groove g formed in the above manner creates a gap at the lower part of the glass 335 placed on the mounting surface 322, allowing the cable to pass through, thereby enabling the space accommodating the cylindrical portion 421 containing the connection end and the cable mounting portions 340, 345 (see reference 322) to accommodate the cable. Figure 7 A channel is formed between them that allows cables to pass through.

[0898] On the other hand, the cooking device in this embodiment may also include a reflector 440 and a protective grille 450.

[0899] Reflector 440 is configured to reflect the heat of the first heating element 400 so that the heat of the first heating element 400 can be concentrated on the tray 200 (see reference). Figure 2 The reflector 440 can be positioned horizontally between the first heating part 400 and the first transverse support part 323, and between the first heating part 400 and the glass 335, and can reflect the heat of the first heating part 400.

[0900] like Figure 41 , Figure 44 as well as Figure 45 As shown, the reflector 440 may include a first reflector section 441 and a second reflector section 445.

[0901] The first reflector portion 441 can be disposed between the first heating portion 400 and the glass 335. Such a first reflector portion 441 is provided in a form that can be positioned horizontally between the first heating portion 400 and the glass 335 and between the first heating portion 400 and the first transverse support portion 323.

[0902] The first reflector portion 441 may be formed to obliquely span the surface between the first heating portion 400, the first lateral support portion 323, and the glass 335. In this embodiment, the first reflector portion 441 is shown as being formed in an arc-shaped oblique shape, for example, similar to a "つ" shape.

[0903] The second reflector section 445 can be disposed between the first reflector section 441 and the glass 335. Such a second reflector section 445 is configured to be able to block horizontally between the first reflector section 441 and the glass 335.

[0904] The second reflector portion 445 can be formed as a plane parallel to the glass 335. Such a second reflector portion 445 can be connected to the first reflector portion 441 at the upper part of the first reflector portion 441.

[0905] The reflector 440 can be formed by bending a metal plate, so that the first reflector portion 441 and the second reflector portion 445 are integrally connected. For example, by bending a metal plate, the first reflector portion 441 disposed at the upper part and the second reflector portion 445 disposed at the lower part can be connected to form a "て" shape, thereby forming the reflector 440.

[0906] Furthermore, the reflector 440 can be made of a metal material that is capable of elastic deformation. In such a reflector 440, the first reflector portion 441, which is formed in an arc shape in particular, can elastically deform in the vertical or front-back direction.

[0907] Furthermore, a space can be formed between the first reflector portion 441 and the second reflector portion 445 arranged in the vertical direction, which is surrounded by the first reflector portion 441, the second reflector portion 445 and the first transverse support portion 323.

[0908] The space formed in this way can be a space to suppress heat transfer between the first reflector section 441 and the second reflector section 445. That is, the space can serve to suppress heat transfer from the first heating section 400, which is arranged adjacent to the first heating section 400, to the second reflector section 445.

[0909] Therefore, the temperature of the top surface of the door 300, i.e., the top surface 310 of the door, can be suppressed to a certain extent from rising due to the heat of the first heating part 400.

[0910] The reflector 440 can be mounted on the door frame 320 by combining with the second lateral support 324 and the cover a.

[0911] Therefore, a first reflector support protrusion l can be provided in the second transverse support portion 324, and a second reflector support protrusion m can be provided in the cover a.

[0912] Additionally, the second reflector support protrusion m can be formed to protrude from the cover a. According to this embodiment, the cover a can be formed in a "U" shape that surrounds the reflector 440 from the front, rear, and bottom. Such a cover a may include a bottom surface disposed at the lower part of the reflector 440 and a side wall disposed at the front or rear of the reflector 440.

[0913] The first reflector support protrusion l can be formed to protrude from the second transverse support portion 324 toward the first transverse support portion 323. Such a first reflector support protrusion l can be disposed on the upper part of the reflector 440. At this time, the first reflector support protrusion l can be disposed adjacent to the side wall of the cover a that is adjacent to the second transverse support portion 324.

[0914] The second reflector support protrusion m can be configured to be adjacent to the sidewall of the cover a that is adjacent to the first transverse support portion 323. Such a second reflector support protrusion m can protrude from the bottom surface of the cover a and can protrude from a position spaced apart from the sidewall of the cover a by a predetermined interval.

[0915] The first reflector support protrusion 1 disposed on the upper part of the reflector 440 can constrain the vertical position of the second reflector part 445 by interfering with it. That is, the top surface of the second reflector part 445 contacts the first reflector support protrusion 1 disposed on the upper part of the reflector 440, thereby restricting the vertical position of the second reflector part 445 to the region below the first reflector support protrusion 1.

[0916] The lower end of the first reflector portion 441 is inserted into the space between the side wall of the cover a and the second reflector support protrusion m, thereby achieving an insertion connection between the first reflector portion 441 and the cover a. The insertion connection between the first reflector portion 441 and the cover a, achieved in this manner, can constrain the position of the first reflector portion 441 in the front-rear direction.

[0917] As described above, the position of the second reflector part 445 in the vertical direction can be constrained by the first reflector support protrusion l, and the position of the first reflector part 441 in the front-back direction and vertical direction can be constrained by the second reflector support protrusion m. This allows the reflector 440 to be positioned in the area between the bottom surface of the cover a and the first reflector support protrusion l, as well as in the area between the two side walls of the cover a.

[0918] Furthermore, the reflector 440 is formed to have a length in the vertical direction that is longer than the distance between the bottom surface of the cover a and the first reflector support protrusion l, and can be configured to be elastically deformable in the vertical and front-back directions. Thus, the reflector 440 can be fixed in the inner region of the cover a with the first reflector part 441 inserted into the cover a and the second reflector part 445 inserted into the lower part of the first reflector support protrusion l.

[0919] At this time, the reflector 440 is positioned between the bottom surface of the cover a and the first reflector support protrusion l in a state of contraction in the vertical direction, so that the reflector 440 can be firmly fixed in the inner area of ​​the cover a.

[0920] The reflector 400, which is configured as described above, can be positioned horizontally between the first heating part 400 and the first transverse support part 323, as well as between the first heating part 400 and the glass 335, and can reflect the heat of the first heating part 400, thereby helping to concentrate the heat of the first heating part 400 to the side of the tray 200.

[0921] like Figures 40 to 43 As shown, the protective grille 450 can be configured to transfer heat from the first heating element 400 to the tray 200 side and to protect the first heating element 400. Such a protective grille 450 can be configured to be separated from the first lateral support 323 across the first heating element 400, or it can be configured to be separated from the glass 335 across the first heating element 400.

[0922] The protective grille 450 may include a plurality of steel wires 451. Each steel wire 451 has a length extending along the length direction of the first heating part 400, and is configured to be approximately the same length as the length of the first heating part 400, or slightly longer than the length of the first heating part 400.

[0923] A plurality of steel wires 451 are arranged around the periphery of the first heating part 400 in a manner that is outside the peripheral direction of the first heating part 400. Such a plurality of steel wires 451 can be arranged at predetermined intervals in the peripheral direction of the first heating part 400.

[0924] According to this embodiment, the peripheral area of ​​the first heating part 400 is surrounded by a reflector 440 and a protective grille 450. That is, one side of the first heating part 400 in the front-rear direction and the upper part of the first heating part 400 are surrounded by the reflector 440, and the other side of the first heating part 400 in the front-rear direction and the lower part of the first heating part 400 are surrounded by the protective grille 450.

[0925] Thus, a plurality of steel wires 451 are arranged in such a way that they surround the other side of the first heating part 400 in the front-back direction and the lower part of the heating part 400 on the outer side of the first heating part 400 in the peripheral direction.

[0926] The protective grille 450 can be mounted on the door frame 320 by fixing its two ends along its length to the first connecting end fixing part 326 and the second connecting end fixing part 327, respectively.

[0927] For this purpose, a grille fixing part can be provided at the first connecting end fixing part 326 and the second connecting end fixing part 327 respectively. The grille fixing part is configured as a means for fixing the steel wire 451 of the protective grille 450 to the heater mounting part 325, and may include a plurality of fixing ribs h.

[0928] A plurality of fixing ribs h are arranged at predetermined intervals along the arrangement direction of a plurality of steel wires 451. Furthermore, each fixing rib h can be formed to protrude from the cover a towards the first heating section 400. Thus, a fixing groove can be formed between the fixing ribs h. Preferably, the interval between the fixing ribs h is determined such that the fixing groove is formed with a width corresponding to the thickness of the steel wire 451.

[0929] As described above, the insertion and connection between the protective grille 450 and the grille fixing part can be achieved by inserting and fixing the steel wire 451 into the fixing slots formed between the plurality of fixing ribs h. Thus, the protective grille 450 can be easily and quickly installed in the door frame 320 by simply inserting and fixing the two ends of the protective grille 450 into the grille fixing parts formed in the first connecting end fixing parts 326 and the second connecting end fixing parts 327.

[0930] In addition, as mentioned above, the plurality of fixed ribs h protruding from the cover a can serve as reinforcing structures to improve the strength of the cover a.

[0931] On the other hand, the heater mounting portion 325 may also include a grid support portion 328. The grid support portion 328 may be disposed between the first connecting end fixing portion 326 and the second connecting end fixing portion 327. Such a grid support portion 328 can serve to support the steel wire between the first connecting end fixing portion 326 and the second connecting end fixing portion 327.

[0932] The grille support 328 may include a cover 328a and a plurality of fixing ribs 328b. The cover 328a may be formed in the same or similar shape as the cover a of the first connecting end fixing part 326 or the second connecting end fixing part 327. For example, the cover 328a may be formed in a U-shape with an open top.

[0933] The plurality of fixing ribs 328b can be formed with the same or similar shape as the fixing rib h of the first connecting end fixing part 326 or the second connecting end fixing part 327. That is, the fixing ribs 328b can be arranged at predetermined intervals along the arrangement direction of the plurality of steel wires 451. Furthermore, each fixing rib 328b can protrude from the cover 328a, thereby forming a fixing groove between the fixing ribs 328b.

[0934] As described above, the insertion connection between the protective grille 450 and the grille support 328 can be achieved by inserting and fixing the steel wire 451 into the respective fixing slots formed between the plurality of fixing ribs 328b.

[0935] As described above, the grille support portion 328 disposed between the first connecting end fixing portion 326 and the second connecting end fixing portion 327 can support the protective grille 450 between the first connecting end fixing portion 326 and the second connecting end fixing portion 327, thereby suppressing the sagging of the central portion of the protective grille 450 in the length direction and making the fixing of the protective grille 450 more stable.

[0936] On the other hand, such as Figure 55 and Figure 59 As shown, a grid through-hole may be provided in the cover a of either the first connecting end fixing part 326 or the second connecting end fixing part 327. In this embodiment, the example shown is that the cover a of the first connecting end fixing part 326 has a grid through-hole. Such a grid through-hole can form the channel required for the steel wire 451 of the protective grid 450 to pass through the cover a in the vertical direction.

[0937] The grille through-hole can be provided at one end of the cover a, and more specifically, it can be provided at the end of the cover a facing the second connecting end fixing portion 327. According to this embodiment, the fixing rib h can be disposed between the support wall b and the grille through-hole. The grille through-hole can open toward the second connecting end fixing portion 327 and can include a wide portion n and a narrow portion o.

[0938] The wide portion n can be disposed between the end of the cover a along its length and the fixing rib h. More specifically, it can be disposed between the end of the cover a facing the second connecting end fixing portion 327 and the fixing rib h. Such a wide portion n can be formed to penetrate the cover a.

[0939] The narrow portion o can be disposed between the wide portion n and the fixing rib h, and can be formed as a through cover a. Such a narrow portion o can open toward the second connecting end fixing portion 327. Furthermore, the narrow portion o can be connected to the wide portion n, and can be formed to have a width narrower than the wide portion n.

[0940] At this time, the narrow portion o is formed with a width narrower than that of the wide portion n, and can be disposed in the inner region of the wide portion n in the width direction. Preferably, the narrow portion o is formed with a width wider than that of the wire 451, and can be formed with a width corresponding to the thickness of the ...
