Description

[Technical Field]

[0001] The present invention relates to a cooking device that is built into a kitchen counter, and more particularly to a cooking device that is equipped with a grill section. [Background technology]

[0002] Typically, the cooking chamber of a cooking appliance is designed to simultaneously heat both sides of food ingredients (food) such as bread or fish using heat sources such as sheath heaters or gas burners placed above and below the food, allowing cooking to be performed according to a variety of menus. For this reason, the cooking chamber is equipped with a temperature sensor such as a thermistor, and temperature control according to the menu is performed based on the detected value of the temperature sensor. The cooking chamber typically has an opening on the front side of the cooking appliance, with a door covering the opening. Food is placed in and out by opening and closing the door using a handle (grip) located on the front side of the door. For heat resistance and design reasons, the door is made of a glass plate (door glass) on the front side, allowing the interior of the cooking chamber to be observed through this glass plate. The glass plate serves as a viewing window through which the interior of the cooking chamber can be observed.

[0003] The grill section of a cooking device installed in a system kitchen is positioned less than one meter above the floor, so the handle protruding from the door glass makes it difficult to work, as it can get caught on clothing when moving around during cooking. Furthermore, the handle is easily soiled by oil and moisture from cooking ingredients that splash from the kitchen top during cooking, and its complex shape makes cleaning difficult, resulting in a lack of cleanliness.

[0004] One configuration that overcomes these dissatisfaction is one that does not have a handle on the front side of the door, as described in Patent Document 1. Patent Document 1 discloses a door-opening technique that includes "a grill door that is provided in the front opening of the grill compartment so as to be switchable between an open position and a closed position, a holding means that always holds the grill door in the closed position, a grill pan that moves between a storage position where it is stored inside the grill compartment and an extended position where it is extended through the front opening, and an extension means that extends the grill pan from the storage position to the extended position, and when the grill pan is extended to the extended position by the extension means, the grill door is released from the holding means and moves to the open position." [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Japanese Patent Application Laid-Open No. 2003-343853 Summary of the Invention [Problem to be solved by the invention]

[0006] As described above, the technology described in Patent Document 1 has a mechanism in which the grill door is unlocked by being pushed, and the grill door moves diagonally downwards to open due to its own weight. Therefore, in Patent Document 1, if the user does not support the grill door with their hand, the grill door will move on its own and fully open. In other words, in Patent Document 1, if the grill door is accidentally pushed while in use, the door will open even during heating, which could adversely affect the cooking results, or the user may come into contact with a hot part if they do not notice that the grill door is open.

[0007] Furthermore, when cooking in the grill chamber, it is not possible to take your hands off the grill door and leave it half-open when checking the cooking, tasting the food, or adding seasonings, so the structure is not very convenient.

[0008] An object of the present invention is to solve the above problems and provide a cooking appliance that improves safety and ease of cleaning for the user, while also achieving both good design and ease of use. [Means for solving the problem]

[0009] In order to achieve the above-mentioned object, the present invention provides a cooking appliance comprising a main body constituting an outer shell, a top plate covering the top opening of the main body, a pot mounting section provided on the top plate on which a cooking pot to be cooked is placed, and a grill section arranged below the pot mounting section, wherein the grill section comprises a cooking chamber, a heating means for heating the cooking chamber, a door covering the opening of the cooking chamber and opening and closing to place a cooking pan in and out of the cooking chamber, a stand that is detachable from the door and on which the cooking pan is placed, slide rails that support the door and the stand so that they can move forward and backward, a handle section provided on the door and shielded by the main body when the opening of the cooking chamber is closed, and an opening / closing means for moving the door forward, and an opening / closing control means for controlling the amount of forward movement of the door by the opening / closing means to such an extent that the handle section is exposed. [Effects of the Invention]

[0010] According to the present invention, it is possible to provide a cooking appliance that improves safety for the user and ease of cleaning, while also achieving both good design and ease of use. [Brief explanation of the drawings]

[0012] An embodiment of the cooking device of the present invention will be described in detail with reference to the drawings as appropriate. Note that, although a built-in IH cooking heater equipped with a grill unit will be exemplified below as an example of the cooking device, the present invention can also be applied to a built-in cooking device such as a gas stove. [Example]

[0013] First, the overall configuration of the cooking device Z according to the first embodiment of the present invention will be outlined, and then the detailed structure of the grill section 5 will be described.

[0014] <Overall configuration of the cooking appliance> The cooking appliance Z of this embodiment is a cooking appliance equipped with an IH (Induction Heating) function that generates eddy currents in the bottom of a metal pot placed on the top surface and heats the metal pot itself with Joule heat due to the eddy currents, and a grill function that heats food stored in the cooking chamber with radiant heat from the heater. Note that, as shown in Figure 1 etc., in the following, the front-back, up-down, left-right directions are defined based on the line of sight of the user facing the cooking appliance Z.

[0015] FIG. 1 is a perspective view of a cooking device Z according to a first embodiment of the present invention. FIG. 2 is a perspective view showing a state in which a handle portion 6a of a door 6 is pulled out to a position where it is visible when viewed from above. FIG. 3 is a perspective view showing a state in which the cooking device Z of FIG. 1 is incorporated into a system kitchen 100. FIG. 4 is an exploded perspective view of FIG. 1. FIG. 5 is a cross-sectional view of the cooking device Z shown in FIG. 1 taken along line VV. FIG. 6 is a cross-sectional view of the cooking device Z shown in FIG. 1 taken along line VI-VI.

[0016] As shown in each figure, the cooking device Z includes a main body 1, a top plate 2, a heating coil 3, a substrate 7, and a substrate case 8 that houses the substrate 7. Furthermore, the grill section 5 of the cooking device Z has built-in imaging means 44 (camera) that photographs the cooking chamber 50.

[0017] Cooking appliance Z is built into the kitchen counter of system kitchen 100. System kitchen 100 is provided with one or more storage sections 101, which are located below built-in cooking appliance Z.

[0018] The main body 1 is a housing that forms an outer shell corresponding to the space (predetermined left-right width, front-back width, and height) in which the cooking appliance Z is installed, and has a box-like (concave) shape that is open at the top. Inside the main body 1, a grill unit 5 is arranged on the left side, and a circuit board case 8 is arranged on the right side.

[0019] Additionally, above the grill section 5 and the base case 8, there are installed a heating coil 3, a display board 22a, an operation board 23a, etc., and a top plate 2 is installed to cover the top opening of the main body 1. The top plate 2 is configured from a plate glass (not shown) on which a cooking pot is placed and a frame (not shown) that holds the four sides of the plate glass, and is installed on top of the main body 1. The top plate 2 is equipped with a display section 22, for example, a touch panel, which can display menu selections and images captured by an imaging means 44 (camera) described below. The top plate 2 is also equipped with an operation section 23, for example, a capacitive switch, and has a touch section 1b (electric control switch) that controls the heat and opens the door 6 described below.

[0020] Grill section 5 on the left front side of main body 1 has an opening (not shown) that slides back and forth to place food 57, and a door 6 is provided to cover this opening. Door 6 opens and closes to load and remove cooking pan 58 into cooking chamber 50.

[0021] Furthermore, a front panel 1a is disposed on the right side of the front of the main body 1, and is positioned so as to be substantially flat on the wide door glass 6b in front of the door 6. As shown in Fig. 1, in this embodiment, the front side of the door 6 is formed by the door glass 6b, and the front panel 1a and the front side of the main body form substantially the same surface.

[0022] In this embodiment, the handle portion 6a of the door 6 is covered by the main body 1 when the opening of the cooking chamber 50 is closed (FIG. 1), and is exposed when the door 6 slides forward. Therefore, when the door 6 is closed, it can be designed to be approximately flat with the front of the system kitchen 100, as shown in FIG.

[0023] As shown in Figures 4 and 5, the board case 8 is a case that houses electrical components such as boards 7 inside. A cooling fan unit 9 is provided on the rear side of the board case 8, which draws in outside air from an intake opening H1 on the rear of the main body 1 and supplies cooling air into the board case 8 from an outlet 95, thereby cooling the multiple boards 7 arranged inside the board case 8. The board case 8 also has a duct D1 that supplies cooling air to the heating coil 3, and the cooling air is supplied from this duct D1 to cool the heating coil 3. The electronic components on the board 7 here include integrated circuits, inverter circuits, capacitors, resistors, etc. that are used to supply high-frequency current to the heating coil 3 and drive the fan unit 9.

[0024] The top plate 2 has a three-burner pot mounting section 21 corresponding to the installation positions of the three heating coils 3, an operation section 23 for setting the heating level of a metal pot placed on the pot mounting section 21, a display section 22 that mainly displays images of the inside of the cooking chamber captured by the imaging means 44, and an exhaust opening H2. The exhaust opening H2 is the outlet for the air path that starts from the exhaust duct 59 of the grill section 5 (described later) and the intake opening H1, and is located at the rear (right and left sides) of the top plate 2. The exhaust opening H2 is also equipped with an exhaust cover 25 that prevents foreign matter from entering.

[0025] <Configuration of grill section 5> As shown in each figure, the grill section 5 is located below the pot placement section 21. The grill section 5 of this embodiment is equipped with a box-shaped cooking chamber 50 with an opening on the front for putting food in and taking it out. This cooking chamber 50 is constructed by assembling multiple members, each formed into a predetermined shape by pressing aluminum alloy plates, with screws or the like.

[0026] In this cooking chamber 50, food is cooked in a deep-plate-shaped cooking pan 58 placed on a stand 54. The cooking pan 58 is a deep plate made of a material such as aluminum and formed in a rectangular shape when viewed from above, and the surface is coated with a fluorine coating agent or the like.

[0027] Inside cooking chamber 50, upper heater 51a and lower heater 51b are installed to sandwich cooking pan 58, and by controlling the on / off of both heaters, it is possible to heat the top and bottom of food in cooking pan 58 simultaneously or alternately. Heating means 51 is a heat source that uses radiant heat, such as a sheath heater or electric heater.

[0028] In this grill section 5, a pair of slide rails 56, located on the left and right lower sides of the cooking chamber 50, allows the door 6 for closing the front opening of the cooking chamber 50 to slide back and forth. The slide rails 56 are comprised of an inner member 56a and an outer member 56b, as described below. The inner member 56a moves inside the outer member 56b, allowing the door 6 and base 54, connected to the inner member 56a, to move back and forth. The slide rails 56 support the door 6 and base 54 so that they can move back and forth. A rubber gasket (not shown) can be provided on the outer periphery of the door 6 on the cooking chamber 50 side to further enhance the airtightness of the front opening of the cooking chamber 50. The base 54 for placing the cooking pan 58 is connected to and held by the slide rails 56 via a connecting plate 54a and can slide back and forth in conjunction with the door 6, which is detachably attached to the connecting plate 54a. The detachable door 6 can be removed from the grill section 5 and cleaned when it becomes dirty.

[0029] An exhaust duct 59 is provided above the rear side of cooking chamber 50 to exhaust oily smoke and steam from inside cooking chamber 50, and is configured to exhaust from exhaust opening H2 provided at the rear of top plate 2 (see Figure 6). In addition, exhaust duct 59 is equipped with a catalyst 55 that breaks down the smoke and odors exhausted from exhaust opening H2 into water vapor and carbon dioxide and then discharges them.

[0030] As shown in Figure 5, in this embodiment, imaging means 44, such as a camera, is provided on the outside of the left wall of cooking chamber 50, and is configured so that food 57 being cooked in cooking pan 58 can be photographed by imaging means 44 through a viewing window 41 provided in the wall of cooking chamber 50. Imaging means 44 is installed in storage case 42, which forms an air passage, and storage case 42 is positioned so that viewing window 41 is located opposite imaging means 44, forming an air passage that communicates with blower fan 40 provided above cooking chamber 50. The better the air-blowing characteristics of blower fan 40, the larger its external dimensions will be. Therefore, it is easier to select a fan with good air-blowing performance by placing it in the space above cooking chamber 50 where heating coil 3 is located, rather than in the narrow space between cooking chamber 50 and the outer casing of main body 1.

[0031] The blower fan 40 is configured as a blower type, for example a centrifugal fan or multi-blade fan, with its intake side facing the intake port 1d provided on the side of the outer casing of the main body 1 and its discharge side facing the storage case 42, and efficiently guides the air sucked in from the side intake port 1d downward and blows it to the imaging means 44 inside the storage case 42.

[0032] In Example 1, as shown in Figure 6, lighting means 43, such as an LED (Light-emitting diode), is arranged on the same wall side of the cooking chamber 50 as the imaging means 44. The lighting means 43 is installed to capture clear images from the imaging means 44. Therefore, the installation position, number of lighting means 43 installed, and light intensity of the lighting means 43 in the cooking chamber 50 are determined appropriately depending on the shape of the cooking chamber 50 and the position of the imaging means 44. Note that the lighting means 43 may be arranged inside the storage case 42 together with the imaging means 44 depending on the need for cooling.

[0033] <Door structure> As shown in Figure 6, the door 6 is a box body 60 having a space inside. The box body 60 is box-shaped with an open front side (front side), and a door glass 6b having approximately the same width as the front panel 1a is provided on the front side (front side) of the open box body 60. A recess that serves as a handle portion 6a is provided behind the door glass 6b and above the box body 60, and this handle portion 6a is positioned so that it cannot be seen when viewed from the front of the main body. The box body 60 is made of metal.

[0034] In the door 6 of this embodiment, the box body 60 defines an air passage 6c and an air layer 6f. The air passage 6c has multiple openings, namely, intake openings 6e and exhaust openings 6d, located above and below the air passage 6c, forming a cooling mechanism. The intake openings 6e and exhaust openings 6d are located above and below the box body 60. When the box body 60 heats up, air is drawn in through the intake openings 6e due to the chimney effect and exhausted through the exhaust openings 6d. Natural convection creates an upward airflow within the air passage 6c, cooling the door glass 6b. The air layer 6f is separated from the air passage 6c. The air layer 6f restricts the air flow, forming an insulating layer of air with low thermal conductivity, reducing the amount of heat escaping from the cooking chamber 50 toward the door glass 6b. The fan supplying cooled air to the box body 60 can be located inside the door 6 or within the main body via a separate air passage. Any cooling mechanism is acceptable.

[0035] <Door opening and closing mechanism> Fig. 7 is a schematic diagram of the grill section of Fig. 5 cut along the left-right direction. Fig. 8A is a schematic diagram of the grill section of Fig. 6 cut along the front-rear direction. Fig. 8B is a schematic diagram showing the state in which the door has been moved forward from the state of Fig. 8A. In the schematic diagram, food 57 is placed on cooking pan 58 to simulate cooking conditions inside cooking chamber 50.

[0036] In the first embodiment, as shown in Figure 7, an opening / closing means 10 is provided below the cooking chamber 50. The opening / closing means 10 is in contact with a connecting plate 54a of a base 54 to which the door 6 is connected, and the door 6 can be slid by pushing the connecting plate 54a forward with the opening / closing means 10. The opening / closing means 10 is, for example, an actuator such as a solenoid that converts electrical energy into mechanical linear motion. The actuator is operated by a touch section 1b (electrically controlled switch) provided on the top plate 2.

[0037] As shown in FIGS. 8A and 8B , the opening / closing device 10 (solenoid) includes a drive unit 10a that moves when an electric current is supplied. The drive unit 10a presses the connecting plate 54a, causing the handle 6a of the door 6 to move to a position where it is visible (exposed) when viewed from above. The user can then pull out the door 6 by placing their hand on the handle 6a. The drive unit 10a, which determines the amount of movement of the door 6, serves as the opening / closing control unit. To achieve a movement of the door 6 greater than the amplitude of the drive unit 10a, the opening / closing control unit may be configured to push the connecting plate 54a or the door 6 via, for example, a link mechanism or a cam mechanism, thereby reducing the size of the opening / closing device 10 (actuator). The opening / closing device operates in conjunction with the touch portion 1b of the top plate 2 shown in FIG. 1. The amount of protrusion of the door 6 caused by the drive unit 10a (opening / closing control unit) of the opening / closing device 10 is controlled to be smaller than when the door 6 is fully open. In a typical cooking appliance, the door moves approximately 300 mm when fully open. In this embodiment, the movement of the door 6 by the drive unit 10a is set to approximately 30 mm. In other words, the movement of the door 6 by the drive unit 10a is set to 1 / 10 or less of the movement when the door 6 is fully open. In this embodiment, the drive unit 10a controls the amount of forward movement of the door 6 by the opening / closing means 10 to such an extent that the handle portion 6a is exposed.

[0038] 3, the front side of the system kitchen 100 is smooth, and only when the door 6 is opened can the user operate the touch portion 1b to open the door 6 just far enough to see the handle portion 6a, and then easily pull the door 6 toward themselves by holding the handle portion 6a. Therefore, this embodiment can prevent the door from accidentally being fully opened and the user from touching the hot door, and can also prevent the door from interfering with cooking.

[0039] In a typical system kitchen, the height from the floor to the top plate 2 is about 800 mm, and the height of the center of the door 6 of the grill section 5 is about 700 mm. For this reason, it is important for the user to know whether the door 6 is open or closed while cooking in the kitchen.

[0040] Furthermore, when the door 6 is closed, there are usually few irregularities on the front side, so that it is difficult for oil smoke or scattered food to get dirty when cooking on the top plate 2, or it is easy to wipe off the dirt, making it easier to keep the kitchen area clean.

[0041] (Variation 1) Next, Modification 1 will be described with reference to Fig. 9 and Fig. 10. Fig. 9 is a perspective view of a cooking device Z according to Modification 1 of Example 1. Fig. 10 is a cross-sectional view of the board case side of cooking device Z in Fig. 9 cut along the front-rear direction. In Fig. 10, a control board 24 that sends an electric signal to opening / closing means 10 is provided behind front panel 1a.

[0042] In the first modification, the front panel 1a is printed with a position indicating the touch area 1b. When the user touches the touch area 1b, which serves as an electric control switch, the control board 24 detects this and the opening / closing means 10 operates. The position of the touch area 1b may be indicated by a light such as an LED. This allows for a wider range of use of the operation area 23 on the top plate 2, and increasing the touch area of ​​the operation area 23 improves the usability of the cooking appliance.

[0043] (Variation 2) Next, Modification 2 will be described with reference to Fig. 11. Fig. 11 is a perspective view of a cooking device Z according to Modification 2 of the first embodiment.

[0044] In the second modification, the handle portion 6a is disposed on the side surface of the door 6, and the touch portion 1b, which is an electric control switch linked to the opening / closing means 10, is provided on the door glass 6b.

[0045] In Modification 2 shown in Fig. 11, the handle 6a is provided on the side (right side) of the box 60 that constitutes the door 6, and is positioned so that the temperature of the door 6 is less likely to rise than on the top. The handle 6a that the user touches must be kept at a safety upper limit temperature of, for example, 60°C or less, and if the temperature is less likely to rise, the cooling means can be configured more simply. Furthermore, by providing the touch portion 1b near the handle 6a, the series of actions required to open the door can be made shorter, resulting in an easy-to-use door configuration.

[0046] <Grilling operation> Next, the cooking operation when using the grill will be specifically described with reference to Figures 1 to 8. Here, the explanation will be given taking as an example a case where food 57 placed on cooking pan 58 of cooking chamber 50 is cooked in cooking device Z installed in a system kitchen.

[0047] First, the user presses touch section 1b on top plate 2. When touch section 1b accepts the touch operation, drive section 10a of opening / closing means 10 operates and presses door 6. Pressed by drive section 10a, door 6 moves forward, exposing handle section 6a. The user pulls handle section 6a to open the front opening of cooking chamber 50 and places cooking pan 58 containing food on stand 54. After pressing door glass 6b to place stand 54 in cooking chamber 50, the user sets the cooking temperature and time using operation section 23 provided on top plate 2 and presses the start button (not shown) on operation section 23. Cooking appliance Z receives operation from operation section 23 and begins grill cooking. Then, as cooking appliance Z begins cooking, fan device 9 of main body 1 is driven, upper heater 51a or lower heater 51b is energized, and food 57 is heated. Furthermore, the lighting means 43 in the cooking chamber 50 is turned on, the blower fan 40 is driven, and the imaging means 44 starts taking pictures of the food 57.

[0048] The state of the kitchen 50 during cooking is projected onto the display 22 on the top plate 2, allowing the user to keep track of what's happening inside the kitchen 50 while doing other tasks in the kitchen. If there is a discrepancy between the initial heating setting on the operation unit 23 and the food's finished state, the user can easily achieve their desired doneness by adding more heating time or stopping the heating midway and removing the cooking pan 58. This configuration allows for efficient heating, as there is no need to repeatedly check the doneness of the food by opening the door (allowing heat to escape). Also, there is no need to repeatedly check through the door window (while bending over), so cooking can be done with less strain on the body due to posture.

[0049] When cooking is finished and the cooking pan 58 is to be removed, the touch portion 1b on the top plate 2 is pressed to move the door 6 forward, as when the food 57 was first placed inside, and the handle portion 6a is pulled to pull out the cooking pan 58 together with the stand 54 for use.

[0050] Thus, with the configuration of this embodiment, even if the user stands in front of the door 6 of the grill section 5 from the time food is placed in the cooking chamber 50 to the time cooking settings are made, there are no uneven surfaces that could catch clothing, and the user can easily approach the top plate 2 and operate it with peace of mind. Therefore, even when checking the display on the top plate 2 during cooking, it is easy to move to the front of the main unit, making grill cooking easy to use.

[0051] Therefore, by reducing the unevenness on the front side of the main body, it is possible to open and close the grill door with increased safety and ease of cleaning, and it is possible to provide a heating cooker with a highly designed design that matches a system kitchen. [Example]

[0052] Next, a second embodiment of the present invention will be described with reference to Figures 12 to 14. Note that the same reference numerals are used to designate the same components as in the first embodiment, and detailed descriptions thereof will be omitted.

[0053] Fig. 12 is a schematic diagram of the grill section 5 of the cooking device Z according to Example 2 of the present invention cut along the left-right direction. Fig. 13 is a schematic diagram of the grill section 5 of the cooking device Z according to Example 2 of the present invention cut along the front-rear direction. Fig. 14 is a schematic diagram showing a state in which the handle section 6a is exposed from the state shown in Fig. 13.

[0054] In the second embodiment, the opening / closing means 10 is arranged on the slide rail 56, which is different from the first embodiment. In addition, the heating means 51 (upper heater 51a, lower heater 51b), which is a flat electric heater, is arranged on the outer wall surface of the cooking chamber 50, resulting in a structure with few irregularities inside the chamber.

[0055] As described above, the slide rail 56 is composed of an inner member 56a and an outer member 56b, and the door 6 and the platform 54 connected to the inner member 56a can be moved by the inner member 56a moving inside the outer member 56b. In this embodiment, the opening / closing means 10 is provided on the outer member 56b of the slide rail 56, and a protrusion 56c is provided on the inner member 56a connected to the platform 54 and the door 6. When the drive unit 10a of the opening / closing means 10 presses the protrusion 56c, the inner member 56a moves, and the door 6 moves to a position where the handle 6a can be seen in a top view.

[0056] This allows the opening / closing means 10 to be placed in the large surplus space behind the cooking chamber 50, making it less susceptible to the effects of exhaust heat from the cooking chamber 50. This improves the reliability of the actuator, allowing for stable operation.

[0057] Furthermore, in the second embodiment, the opening / closing means 10 can be easily configured as a push latch that is driven by the reaction force of pushing the door, rather than an electric mechanism. [Example]

[0058] Next, a third embodiment of the present invention will be described with reference to Figures 15 and 16. Note that the same reference numerals are used to designate the same components as those in the first and second embodiments, and detailed descriptions thereof will be omitted.

[0059] Fig. 15 is a perspective view of a cooking device Z according to Example 3 of the present invention. Fig. 16 is a schematic view of the grill section 5 of the cooking device Z of Fig. 15 cut along the front-rear direction.

[0060] The third embodiment differs from the first embodiment in that a push latch type opening / closing means 10 is provided inside the door 6.

[0061] In the third embodiment, the door 6 is provided with a push-latch type opening / closing means 10 at the top and a pivoting portion 6g at the bottom. The push-latch opening / closing means 10 pushes the door 6 in the closing direction, and the reaction force drives the door 6 in the opening direction. In the third embodiment, the door 6 is separated in the front-rear direction at an upper position with the pivoting portion 6g as a fulcrum, and the rear of the door glass 6b that has been tilted forward becomes the handle portion 6a. The door glass 6b is then tilted to expose the handle portion 6a.

[0062] The door 6 is also provided with a pivoting hinge 10b that stops the door glass 6b at a predetermined angle when the door glass 6b pivots and separates. In the third embodiment, the predetermined angle at which the door glass 6b opens is set to about 10 degrees. When the door glass 6b opens to 10 degrees, the handle portion 6a is exposed. The pivoting hinge 10b functions as an opening / closing control means that controls the amount of movement of the door glass 6b.

[0063] As a result, the mechanisms for exposing the handle portion 6a are all housed within the door 6, thereby providing a configuration in which no structural changes are required around the main body 1 and the cooking chamber 50.

[0064] The present invention is not limited to the above-described embodiments, but includes various modifications. The above-described embodiments have been described in detail to clearly explain the present invention, and are not necessarily limited to those including all of the described configurations. Furthermore, it is possible to replace part of the configuration of one embodiment with the configuration of another embodiment, and it is also possible to add the configuration of another embodiment to the configuration of one embodiment. Furthermore, it is possible to add, delete, or replace other configurations with respect to the configuration of each embodiment. [Explanation of symbols]
