Description

Technical Field

[0001] This utility model relates to cooking equipment, and more specifically, to a cooking device disposed on the upper side of a heating cooking apparatus. Background Technology

[0002] The content described in this section is only to provide background information on this utility model and does not constitute prior art.

[0003] Cooking appliances are household appliances that use microwaves, a type of electromagnetic wave, and / or heat from heaters to cook food. Typically, cooking appliances have a cavity that serves as a space for placing and cooking food, and a door that allows the cavity to be opened and closed.

[0004] When installing cooking equipment indoors, it is necessary to consider the effective use of the equipment and the saving of installation space.

[0005] For this reason, cooking equipment can be positioned near heating cooking devices such as ovens or gas stoves. Specifically, cooking equipment can be positioned above heating cooking devices.

[0006] By placing the cooking equipment above the heating element, users can reduce movement in environments where the cooking equipment and heating element are close together, thus making food preparation more convenient. Additionally, the cooking equipment can be used as a hood to expel hot air, oil vapors, and other contaminants generated by the heating element to the outside.

[0007] For example, a display can be installed on the front of the door of the cooking appliance to provide users with various information. Users can use the display to check the cooking status of the food.

[0008] Furthermore, when the display unit is connected to other home appliances and acts as a hub for them, it can provide information beyond just food cooking data. Additionally, cooking instructions and various other commands can be input to the display unit via touch. Utility Model Content

[0009] The purpose of this invention is to provide a cooking device that includes a door with a structure capable of effectively cooling the display section.

[0010] In addition, the purpose of this invention is to provide a cooking device with a structure that can increase the airflow inside the door.

[0011] The purpose of this utility model is not limited to the purposes mentioned above. Other purposes and advantages of this utility model not mentioned can be understood through the following description and will become clearer through the embodiments of this utility model. In addition, it can be readily understood that the purposes and advantages of this utility model can be achieved by the means and combinations thereof given in the claims.

[0012] One embodiment of the cooking apparatus may include a body forming a cavity and a door for opening and closing the cavity.

[0013] The door may include a display module disposed in front of the door. The door may also include a cooling flow path disposed behind the display module. An airflow path for cooling may be formed inside the cooling flow path.

[0014] The cooling flow path may include an inner panel disposed behind the display module. The inner panel may be mounted on the display module. The cooling flow path may include an air guide disposed between the display module and the inner panel. The air guide may be integrated with the inner panel.

[0015] The air guide may include guide ribs protruding from the upper part of the panel. The guide ribs can guide the flow direction of air flowing into the air guide.

[0016] The air guide may include at least one inlet disposed at the top for the inflow of external air. The air guide may include an exhaust port formed at the bottom of the inlet for the exhaust of air. A fan may be disposed at a position overlapping the exhaust port in the front-rear direction of the door. Guide ribs may be formed to extend from the edge of the inlet.

[0017] The air guide may include an upper protruding wall connected to the inner edge of each of a pair of inlets. The upper protruding wall may be formed protruding toward the inner panel at the upper end of the air guide. Guide ribs may extend from the upper protruding wall.

[0018] Therefore, guide ribs can be positioned at the boundary between the upper protruding wall and the inlet.

[0019] The length direction of the guide rib can be configured in a direction that is inclined relative to the vertical and lateral directions of the air guide.

[0020] The guide rib can be configured to extend downward from the upper protruding wall toward the lower side of the air guide and approach the outer edge of the air guide.

[0021] The guide ribs can be configured to at least partially prevent the lateral airflow formed on the upper part of the air guide from mixing with the lateral airflow formed at the inlet.

[0022] Forced airflow, driven by a blower fan, flows into the blower fan from the inlet and downwards towards the blower fan. The forced airflow passes through the blower fan and exhaust vent along the front-to-back direction of the door. After being split vertically in front of the air guide, a portion of the forced airflow flows upwards towards the door and exits through the first exhaust outlet, while the other portion flows downwards towards the door and exits through the second exhaust outlet.

[0023] In the cooking device of this invention, similar to the air discharged from the second outlet, the air discharged from the first outlet can form an air curtain to prevent oil vapor and other substances from adhering to the front of the display section.

[0024] In addition, the airflow direction from the first row of outlets can be changed by the panel to be discharged towards the lower side of the door, so that at least a portion of it can come into contact with the front of the display unit.

[0025] With this structure, the air exhausted from the first row of outlets can directly contact the front of the display unit to cool it. Therefore, both the front and back of the display unit are cooled by air, significantly improving cooling efficiency compared to cooling only the back of the display unit.

[0026] Furthermore, in the cooking apparatus of this invention, the guide ribs can be formed by extending from the upper protruding wall. Therefore, the guide ribs can be positioned at the boundary between the upper protruding wall and the inlet.

[0027] Therefore, guide ribs can effectively reduce the formation of vortices by preventing airflows with different directions from meeting each other. This, in turn, increases the airflow rate inside the air guide.

[0028] In addition, in the cooking device of this invention, at the upper part of the air guide, the lateral airflow can change its flow direction along the inclined direction of the guide rib and flow downward.

[0029] With this structure, the lateral airflow can avoid rising or stagnating at the position adjacent to the guide rib. Therefore, it is possible to effectively suppress the formation of vortices caused by air rising or stagnating in the air guide.

[0030] By suppressing the formation of eddies, the air velocity and flow rate inside the air guide are increased, thereby improving the cooling effect of the door.

[0031] In addition to the effects described above, the specific effects of this utility model will be described together with the following description of the specific matters for implementing the utility model. Attached Figure Description

[0064] Figure 1 This is a perspective view of a cooking apparatus according to an embodiment. Figure 2 It is shown in Figure 1 A diagram showing the middle gate 20 in an open state.

[0065] The cooking device in the embodiment can be positioned above a location where a heating cooking device, such as a heated oven or a gas stove, is located vertically separated from the heating cooking device.

[0066] With this configuration of cooking equipment, users can conveniently use the cooking apparatus, which includes the cooking device. Furthermore, the cooking apparatus can function as an exhaust hood for the heating cooking device located below. In this case, the cooking apparatus may have a component that serves as an exhaust hood.

[0067] The cooking device can use microwaves, which are a type of electromagnetic wave, and / or heater heat to cook food. The cooking device may include a body 10 forming a cavity 11 and a door 20 for opening and closing the cavity 11.

[0068] Food to be cooked can be placed in the cavity 11. The door 20 can be configured in front of the cavity 11 and rotatably mounted on the main body 10, so that the cavity 11 can be opened and closed.

[0069] The cooking equipment can function as an exhaust hood to expel foreign matter in the form of gaseous substances from the heating and cooking device located below to the outside. For this purpose, a vent 13 can be provided on the upper part of the main body 10 to expel moisture, oil vapor, etc. generated from the heating and cooking device located below the cooking equipment to the outside.

[0070] The main body 10 may also include a front panel 12, which is disposed at the entrance edge of the cavity 11. When the door 20 is closed, one side of the front panel 12 is configured to face the side of the choke member 170 to close the cavity 11.

[0071] The front panel 12 can surround the entrance edge of the cavity 11 and can be configured to protrude by a specified width. Therefore, when the door 20 is closed, the edge portion of the door 20 and the cavity 11 can overlap each other.

[0072] With this structure, the front panel 12 seals the cavity 11 when the door 20 is closed, thereby preventing oil, moisture, oil vapor and other substances generated during the cooking process of food placed in the cavity 11 from flowing out to the outside through the inlet of the cavity 11.

[0073] Figure 3 Observing from another direction Figure 1 The image. Figure 4 This is a bottom view of a cooking apparatus according to an embodiment.

[0074] A suction section 14 can be provided at the lower part of the main body 10 to draw in moisture, oil vapor, etc. rising from the heating and cooking device. Therefore, the cooking device can function as an exhaust hood that draws in air discharged from the heating and cooking device located below it and discharges it to the outside.

[0075] The intake section 14 and the vent 13 are configured to communicate with each other. Gases such as oil vapor flowing into the intake section 14 can be discharged to the outside through the vent 13. The vent 13 can be configured to communicate with a pipe connected to the outside.

[0076] On the other hand, the cavity 11 of the cooking device is formed to be not connected to the suction section 14 and the vent 13, so that the oil vapor and other gases flowing in from the suction section 14 will not flow into the cavity 11, and can be directly discharged to the outside of the main body 10 through the vent 13.

[0077] A bottom panel 15 is provided at the lower part of the main body 10, and the intake part 14 can be formed to communicate with the ventilation hole 13 through the bottom panel 15.

[0078] A lighting section 25 that illuminates downwards can be formed on the bottom panel 15. This lighting can be, for example, shaped to be elongated along the side of the cooking appliance. With the illumination from the lighting section 25, the user can conveniently use the heating cooking device located on the lower side of the cooking appliance.

[0079] Figure 5 This is a perspective view showing the door 20 of a cooking appliance according to an embodiment. Figure 6 Observing from another direction Figure 5 The image.

[0080] Figure 7 This is the rear view of door 20. Figure 8 This is a perspective view showing an exploded portion of a door 20 in one embodiment. Figure 9 Observing from another direction Figure 8 The image.

[0081] The door 20 may include a display module 21, a cooling flow path 22, and a shielding part 23. The display module 21 is disposed in front of the door 20, and the user can use the display module 21 to view the interior of the cavity 11 of the cooking device.

[0082] The cooling flow path 22 is disposed behind the display module 21, and an airflow path for cooling can be formed inside it. The air flowing into the door 20 can flow inside the door 20 and cool the door 20 by utilizing the cooling flow path 22.

[0083] The shielding part 23 is disposed behind the cooling flow path part 22 and can shield electromagnetic waves generated from the main body 10. The shielding part 23 can block electromagnetic waves generated from the cavity 11 and propagating to the outside of the cooking device to protect the user.

[0084] For example, shielding part 23 can block electromagnetic waves (microwaves) generated for cooking food inside the main body 10 from being emitted to the outside of door 20.

[0085] The cooling flow path 22 is provided for cooling electrical components installed inside the door 20, including the display unit 110 installed in the display module 21. Air can flow inside the cooling flow path of the cooling door 20. The display unit 110 can be formed to be thin, and its area can occupy most of one side of the door 20.

[0086] Therefore, the display unit 110 is formed to occupy most of the front area of ​​the door 20, thereby increasing the configuration area of ​​the display unit 110 and improving the user's visibility. The user can conveniently check various information using the display unit 110 with its large screen.

[0087] Because the display unit 110 is larger, the heat generation may increase. Therefore, it is necessary to configure the display unit 110 to be effectively cooled within the door 20. In an embodiment, a cooling flow path for cooling airflow may be additionally provided.

[0088] The cooling flow path 22 is positioned behind the display unit 110 and allows cooling air to flow through it, thus effectively cooling the display unit 110. Additionally, the heat-generating components mounted on the display module 21 can also be cooled by the air flowing through the cooling flow path 22. In other words, the cooling flow path 22 can cool the display module 21, which includes the display unit 110 and various other heat-generating components.

[0089] In order to effectively cool the display unit 110, the entire display unit 110 needs to be exposed to the air flowing in the cooling flow path 22. In addition, it is necessary to form an air curtain by the airflow discharged to the outside of the door 20 through the cooling flow path 22 to block the hot air and oil vapor rising from the heating cooking device located at the bottom of the cooking equipment.

[0090] Therefore, the air flowing in the cooling flow path 22 can be diverted inside the cooling flow path 22 to be discharged to the upper and lower sides of the display module 21.

[0091] Since the cooling air is split inside the cooling flow path 22 and discharged to the upper and lower sides of the display module 21, the cooling air can contact and flow with the entire back side of the display unit 110, thereby effectively cooling the display unit 110.

[0092] In addition, since cooling air is discharged to the upper and lower sides of the display module 21 respectively, an air curtain is effectively formed around the display and the door 20, so that hot air and oil vapor rising from the heating cooking device located at the bottom of the cooking equipment can be effectively blocked by the air curtain.

[0093] The display module 21 may include a display unit 110, a camera, and other electrical components, while the cooling flow path 22 may include electrical components such as a fan 150 operated by a motor. Therefore, in order to protect the user and electrical components from electromagnetic waves, a shielding part 23 that shields electromagnetic waves generated from the main body may be provided behind the cooling flow path 22.

[0094] The display module 21 may be configured with a display section 110 and various electrical components. A cooling flow path section 22, which forms a flow path for cooling the display module 21, may be configured behind the display module 21. A shielding section 23, which shields electromagnetic waves from reaching the electrical components provided on the display module 21, may be configured behind the cooling flow path section 22.

[0095] In this embodiment, the display module 21, used to provide various information and convenience to the user, needs to be positioned on the front of the cooking appliance, i.e., at the very front of the door 20. Additionally, this embodiment requires a structure that effectively cools components such as the display section 110 housed in the display module 21, and simultaneously forms a flow path for cooling air to create an air curtain around the door 20 while effectively cooling the interior of the door 20 where the display section 110 is located, and protects the electrical components installed on the door 20 from electromagnetic waves.

[0096] To meet this requirement, the display module 21 can be positioned at the front of the door 20, the cooling flow path 22 can be positioned behind the display module 21, and the shielding part 23 can be positioned behind the cooling flow path 22.

[0097] That is, in order to realize the door structure of the aforementioned embodiment, the door 20 needs to arrange the display module 21, cooling flow path section 22, and shielding section 23, which each play their respective roles, in sequence from the front to the rear of the door 20.

[0098] The display module 21 may include a first outlet 123 and a second outlet 124. The first outlet 123 may be configured on the upper part of the display module 21, and the air flowing inside the display module 21 may be discharged to the outside through the first outlet 123.

[0099] The second outlet 124 can be configured at the lower part of the display module 21, and the air flowing inside the display module 21 can be discharged to the outside through the second outlet 124. That is, the air flowing inside the door 20 can be discharged to the outside through the first outlet 123 and the second outlet 124 respectively configured at the upper and lower parts of the door 20, so that the air can flow throughout the entire interior of the door 20, thereby effectively cooling the entire door 20.

[0100] The display module 21 may include a display unit 110 and an outer panel 120. The display unit 110 may be configured on the front of the door 20 and display images, videos, or pictures.

[0101] The display unit 110 can display and provide cooking information to the user. Additionally, the display unit 110 can receive user commands via touch recognition.

[0102] On the other hand, the display unit 110 can be communicatively connected to other household appliances, as well as cameras, locking devices, etc. installed on the entrance door. In addition, the display unit 110 can be communicatively connected to external devices required by the user.

[0103] Users can receive information about the operation of home appliances, visits from outsiders, and other aspects of daily life from the display unit 110, and can also use the display unit 110 to send commands to home appliances and other devices connected to the display unit 110.

[0104] Therefore, the door 20, including the display unit 110, can serve as an Internet of Things hub that transmits information about home appliances and other devices needed for daily life to users and transmits user instructions to such devices.

[0105] The outer panel 120 can be disposed behind the display unit 110. The outer panel 120 can be disposed in front of the inner panel 130. The display unit 110 can be mounted on the outer panel 120. The outer panel 120 can be generally formed into a shape having a hollow portion 1201 and a predetermined width along the front-rear direction of the door 20.

[0106] The hollow portion 1201 of the outer panel 120 can be closed by the back of the display unit 110. Air flowing inside the outer panel 120 can collide with the back of the display unit 110 exposed in the hollow portion 1201 of the outer panel 120. Thus, the air flowing inside the outer panel 120 can contact the back of the display unit 110 to cool the display unit 110.

[0107] In addition, the air passing through the fan 152 can cool heat-generating components such as the speaker 260, microphone 270, and printed circuit board that are exposed and disposed in the hollow portion 1201 of the outer panel 120.

[0108] Because the outer panel 120 has the aforementioned structure, it can have an internal space in which various components can be housed. The width of the door 20 in the front-to-back direction can be almost entirely determined by the outer panel 120.

[0109] A first through-hole 121 for air inflow can be formed at the upper end of the outer panel 120. A plurality of first through-holes 121 can be provided. Each first through-hole 121 can be arranged with a plurality of slit-shaped holes spaced apart. Using this structure, external foreign objects can be slightly suppressed from flowing into the interior of the door 20 through the first through-holes 121.

[0110] A handle 122 may be provided on one side of the outer panel 120 for use by the user when opening and closing the door 20. For example, the handle 122 may be formed by a recess in the side of the outer panel 120.

[0111] A button device 300 may be installed on one side of the outer panel 120, for example, directly below the location where the handle 122 is formed. The user can operate the button device 300 to supply power to or cut off the power supply to the cooking appliance. Detailed operation of the cooking appliance can be achieved by inputting commands to the display unit 110.

[0112] The outer panel 120 can support various components such as the display unit 110, speaker 260, microphone 270, and printed circuit boards for communication or control, and can be formed with a first through hole 121 for external air to flow in, a first outlet 123 for air to be discharged, and a second outlet 124.

[0113] On the other hand, a camera can be installed in the door 20. The images captured by the camera can be played on the display unit 110, allowing the user to observe the interior of the cavity 11 or the image below the cooking appliance using the display unit 110. The camera may include a first camera 310, a second camera 210, and a third camera 230.

[0114] The first camera 310 can be configured at the upper front of the display module 21 to capture images of the front of the cooking equipment.

[0115] The first camera 310 can capture images of the user or the interior space located in front of the cooking equipment. Therefore, the first camera 310 can be used when the user uses the display unit 110 to make video calls with others at other remote locations outside the entrance door. The first camera 310 will be described in detail later.

[0116] The second camera 210 can be mounted on the lower part of the outer panel 120 and capture images of the lower part of the door 20. The second camera 210 is mounted on the lower part of the outer panel 120 so that its line of sight is directed towards the lower part of the cooking equipment, thus allowing it to capture images of the heating and cooking device located at the lower part of the cooking equipment. Alternatively, the second camera 210 can be used to monitor the status of the heating and cooking device at the lower part of the cooking equipment.

[0117] Users can use the images captured by the second camera 210 and displayed on the display unit 110 to observe the status of the heating and cooking device and the cooking status of the food in the heating and cooking device.

[0118] The third camera 230 is mounted on the frame 160 and positioned facing the cavity 11, and can capture images of the cavity 11. That is, the line of sight of the third camera 230 can be set to face the cavity 11 and capture images of the cavity 11. The user can use the images captured by the third camera 230 to observe the food cooking process in the cavity 11.

[0119] Door 20 may include a latch 250, which is mounted on the side of frame 160 and a portion of which is formed to protrude from frame 160. The latch 250 may be configured to engage with a groove formed in the front panel 12 of door 20. The latch 250 can stably hold door 20 in a closed state.

[0120] Figure 10 This is an exploded perspective view of gate 20 in one embodiment. Figure 11 Observing from another direction Figure 10 The diagram shows that the cooling flow path 22 may include an inner panel 130, an air guide 140, and an air supply device 150.

[0121] The inner panel 130 can be disposed behind the display module 21 and can be mounted on the display module 21. Specifically, the inner panel 130 can be disposed behind the outer panel 120 and mounted on the outer panel 120. An air guide 140, described later, can be mounted on the inner panel 130. The inner panel 130 and the air guide 140 together form a space for airflow to be drawn into the interior of the door 20.

[0122] Air guide 140 is mounted on inner panel 130, which can be combined with frame 160 to provide space for airflow into the interior of door 20.

[0123] Air guide 140 can be configured between display module 21 and inner panel 130, and can be combined with inner panel 130. Specifically, air guide 140 can be configured between outer panel 120 and inner panel 130, and can be combined with inner panel 130. Air guide 140 can guide the flow of air flowing from the outside into the interior of door 20, and can form a space for airflow.

[0124] The air supply device 150 can be installed on the air guide 140. The air supply device 150 can force the air flowing into the air guide 140 to flow from the rear of the air guide 140 to the front.

[0125] The shielding part 23 may include a frame 160 and a blocking member 170. The frame 160 may be disposed behind and coupled to the inner panel 130, and one side thereof may be rotatably coupled to the main body 10. As the frame 160 rotates, the door 20 may rotate to open and close the cavity 11 of the cooking device.

[0126] The frame 160 can be combined with the inner panel 130 to form a flow path for cooling air while having a shielding structure, i.e., a blocking member 170, to prevent electromagnetic wave leakage, and can form the inner side of the door 20.

[0127] The blocking member 170 can be disposed behind and combined with the frame 160, and can block the electromagnetic waves generated from the main body 10 from being emitted to the outside. The blocking member 170 can generally be formed into a quadrilateral shape with a hollow portion, and can be formed into an edge portion surrounding the frame 160.

[0129] Reference Figure 13 The door 20 may include a speaker 260 and a microphone 270. At least one speaker 260 may be mounted on the side of the outer panel 120. The speaker 260 may generate voice, prompts, etc., required for the operation of the cooking equipment. In addition, the speaker 260 may generate all voice, prompts, etc., for enabling the door 20, including the display 110 of the door 20, to function as an Internet of Things hub.

[0130] Microphone 270 can be mounted on the lower part of the outer panel 120 and can receive user voice. Users can use microphone 270 to input voice commands for operating the cooking equipment. Additionally, microphone 270 can serve as part of enabling door 20 to function as an IoT hub.

[0131] On the other hand, a communication unit for communication can be provided in the door. Since the door 20 functions as an Internet of Things hub, the communication unit provided in the door 20 is preferably configured to perform various types of wired or wireless communication functions.

[0132] The outer panel 120 may have a first through-hole 120c and a second through-hole 120d. The first through-hole 120c may be formed on the side of the outer panel 120. The first through-hole 120c may be located near the position where the speaker 260 is disposed. The first through-hole 120c may be formed in a mesh shape to allow the speaker 260 to communicate with the outside and to prevent the speaker 260 from being exposed to the outside.

[0133] The speaker 260 communicates with the outside of the outer panel 120 via the first through-hole 120c, thereby effectively transmitting prompts and other voice messages to the user. Since there is a pair of speakers 260, the first through-hole 120c can also be a pair and formed at positions corresponding to each speaker in the pair of speakers 260.

[0134] The second through-hole 120d can be formed to penetrate the lower part of one side of the outer panel 120. A portion of the button device 300 installed inside the outer panel 120 can be exposed to the outside of the outer panel 120 through the second through-hole 120d. The user can operate the button device 300 by touching the exposed part of the outer panel 120.

[0135] A first outlet 123 may be disposed on the upper part of the outer panel 120, and a second outlet 124 may be disposed on the lower part. The first outlet 123 is disposed on the upper part of the outer panel 120, allowing air flowing inside the door 20 via the air supply device 150 to be discharged to the outside. The second outlet 124 is disposed on the lower part of the outer panel 120, allowing air flowing inside the door 20 via the air supply device 150 to be discharged to the outside.

[0136] The first outlet 123 can be located adjacent to the upper end of the display unit 110, and the second outlet 124 can be located adjacent to the lower end of the display unit 110. Therefore, the air forced to flow inside the door 20 by means of the air supply device 150 can be discharged to the outside from the positions adjacent to the upper and lower ends of the display unit 110 through the first outlet 123 and the second outlet 124.

[0137] Air discharged through the first outlet 123 can form an air curtain at the top of the door 20. Additionally, air discharged through the second outlet 124 can form an air curtain at the bottom of the door 20.

[0138] An air curtain is a means of blocking external airflow from penetrating into the door 20. In an embodiment, the boundary surface or boundary region where the airflow discharged from the interior of the door 20 via the first outlet 123 and the second outlet 124 forms a boundary with the external airflow can be referred to as an air curtain.

[0139] An air curtain formed by air discharged from the interior of door 20 via the first outlet 123 and the second outlet 124 can suppress the infiltration of external air into door 20.

[0140] Because the heating cooking device is located at the bottom of the cooking equipment, the heat generated when using the heating cooking device and the oil vapor from the food being cooked may rise and penetrate into the cooking equipment.

[0141] The heat transferred from the heating element to the cooking appliance may damage components located on the door 20 of the cooking appliance. In particular, the display unit 110 and components containing circuits, components, etc., related to its operation may be susceptible to heat.

[0142] Additionally, oil vapors transferred from the food being cooked may adhere to the door 20 of the cooking appliance. Oil vapors may adhere to the surface of the display unit 110, reducing its image quality, and may also adhere to the surfaces of other components mounted on the door 20, potentially damaging them.

[0143] In an embodiment, the airflow discharged to the outside of the door 20 via the first outlet 123 and the second outlet 124 provided on the door 20 can form an air curtain, which can effectively block the hot air and oil vapor rising from the heating cooking device located at the bottom of the cooking equipment.

[0144] Therefore, it is possible to effectively prevent various electronic components, including the display unit 110, installed on the door 20 from being damaged or having their functions reduced due to hot air and oil vapor.

[0145] Reference Figure 14 The air guide 140 may include an inlet 141 and an outlet 142. The inlet 141 may be configured on the upper part of the air guide 140 to allow outside air to flow in, and at least one inlet 141 may be provided.

[0146] The inlet 141 can be configured at a position corresponding to the first through hole 121 provided on the upper part of the outer panel 120. Therefore, external air can flow into the interior of the door 20 through the first through hole 121 of the outer panel 120 and through the inlet 141.

[0147] An exhaust port 142 is formed at the lower part of the inlet 141 in the air guide 140, and a blower fan 152 can be arranged at a position that overlaps with the exhaust port 142 in the front-back direction. The exhaust port 142 can be formed to penetrate the air guide 140 in the front-back direction of the door 20.

[0148] Therefore, air can flow from the upper part to the lower part of the air guide 140 through the inlet 141, and then change direction to flow from the rear to the front of the air guide 140 through the exhaust port 142.

[0149] The air supply device 150 may include a housing 151 and an air supply fan 152. The housing 151 may be disposed at the exhaust port 142 and form a hollow portion, in which the air supply fan 152 may be installed.

[0150] The blower fan 152 is rotatably mounted on the housing 151 and allows air to flow from the rear of the air guide 140 to the front. The blower fan 152 can be powered to rotate, thereby causing air to flow inside the door 20.

[0151] With the help of the rotation of the blower fan 152, outside air can flow into the interior of the door 20 through the inlet 141 and can be discharged to the outside of the door 20 through the first outlet 123 and the second outlet 124. The exhaust port 142 of the air guide 140 is formed in the center of the housing 151 and can be formed to correspond to the position, area and shape of the hollow part in which the blower fan 152 is disposed.

[0152] Figure 16 Is Figure 5 The side sectional view of door 20 in the 16-16 direction is observed below. (Refer to the following text.) Figure 16 This specifically describes the airflow inside door 20. Figure 16 In the image, arrows are used to represent the flow of air.

[0153] As the blower fan 152 rotates, outside air can flow into the interior of the door 20 through the inlet 141 of the air guide 140, and can be discharged to the outside of the door 20 through the first outlet 123 and the second outlet 124.

[0154] Specifically, the air forced to flow by the blower fan 152 can have the following flow path.

[0155] Air can flow into the interior of the door 20 through the first through hole 121 of the outer panel 120 and the inlet 141 located thereto. The air flowing into the interior of the door 20 can flow downward toward the door 20 and into the blower fan 152.

[0156] Air can pass through the fan 152 in the front-to-back direction of the door 20. At the same time, air can pass through the exhaust port 142 of the air guide 140 while passing through the fan 152. The airflow direction can be changed from the vertical direction of the door 20 to the front-to-back direction by the fan 152.

[0157] Since the front of the exhaust port 142 is blocked by the display unit 110, the air passing through the exhaust port 142 can be diverted in the vertical direction in front of the air guide 140.

[0158] A portion of the diverted air can flow upward toward the door 20 and exit from the first outlet 123. Another portion of the diverted air can flow downward toward the door 20 and exit from the second outlet 124.

[0159] The air diverted from the first row of outlets 123 and the second row of outlets 124 can surround the entire door 20. In particular, the diverted air can surround the front part of the door 20. With this structure, the air discharged from the first row of outlets 123 and the second row of outlets 124 forms an air curtain in the door 20, thereby effectively suppressing the penetration of hot air and oil vapor generated from the heating cooking device located at the bottom of the cooking equipment into the door 20.

[0160] Furthermore, utilizing the aforementioned structure that allows air to flow inside the door 20, the air flowing into the door 20 can circulate throughout the entire interior of the door 20. For example, air can circulate throughout the entire space formed by the back of the display unit 110 and the outer panel 120.

[0161] Thus, the air flowing inside the door 20 can cool the entire back of the display unit 110, and can effectively cool the outer panel 120 and other components installed on other parts of the door 20.

[0162] In particular, heat-generating components such as a speaker 260, a microphone 270, and a printed circuit board can be installed on the outer panel 120. Such heat-generating components can be distributed throughout the entire outer panel 120. Therefore, air can effectively cool such heat-generating components while flowing throughout the entire interior of the outer panel 120.

[0163] like Figure 16 As shown, the first through-hole 121 and the inlet 141 for air inflow can be connected to each other. As the blower fan 152 rotates, external air can flow into the interior of the air guide 140 through the first through-hole 121 and the inlet 141, and can flow toward the blower device 150 through the space formed by the inner panel 130 and the air guide 140.

[0164] Air can flow from the space formed by the frame 160 toward the air supply fan 152 of the air supply device 150. The air can pass through the air supply fan 152 and collide with the back of the display unit 110 which is arranged facing the air supply fan 152, thereby cooling the display unit 110.

[0165] After passing through the fan 152 and colliding with the back of the display unit 110, the airflow can be split in the upward and downward directions of the display unit 110. The air flowing towards the upper side of the display unit 110 can be discharged to the outside of the door 20 through the first outlet 123 provided on the upper side of the outer panel 120. The air flowing towards the lower side of the display unit 110 can be discharged to the outside of the door 20 through the second outlet 124 provided on the lower side of the outer panel 120.

[0166] In this embodiment, the air flowing inside the door 20 can cool the entire front of the display unit 110 while being discharged through the first outlet 123. Additionally, the air flowing inside the door 20 can effectively cool the back of the display unit 110 and the heat-generating components installed inside the door 20.

[0167] An exhaust port 142 may be formed in the center of the air guide 140. The housing 151 may have a hollow portion corresponding to the position, size, and shape of the exhaust port 142, and a blower fan 152 may be disposed in the hollow portion. The housing 151 may be configured to be placed at a position corresponding to the exhaust port 142 of the air guide 140, and may be mounted on one side of the air guide 140.

[0168] A hollow portion 130a may be formed in the inner panel 130. Since the hollow portion 130a of the inner panel 130 is blocked by the frame 160, the air flowing in through the inlet 141 can not leak from the hollow portion 130a of the inner panel 130. Therefore, the inner panel 130 and the frame 160 can together form an airflow path for the air to flow inside the cooling door 20.

[0169] Figure 17 It is Figure 16 The diagram shows an enlarged view of part 17. The door 20 may include a front joint 24, which is disposed above the display unit 110 and protrudes towards the front of the door 20, and is attached to the outer panel 120. A gap of a predetermined size is formed between the lower part of the front joint 24 and the front of the display unit 110, which serves as a passage for the exhaust of air from the interior of the cooling door 20.

[0170] The front joint 24 may include a detection module 310 and a panel 320. The detection module 310 is disposed at the upper front of the display module 21, detects external conditions, and may have various detection devices.

[0171] The panel portion 320 can be disposed on the upper front of the display module 21. The panel portion 320 can be configured to cover the detection module 310. Since the panel portion 320 covers the detection module 310, the panel portion 320 can form the shape of the front joint portion 24. In this case, the detection module 310 can be accommodated inside the panel portion 320.

[0172] In another embodiment, the detection module 310 may also be configured behind the panel portion 320, rather than being housed inside the panel portion 320.

[0173] The panel portion 320 can be configured to overlap with the display module 21. As another embodiment, the panel portion 320 can also be configured on the upper side of the display module 21 without overlapping with the display module 21.

[0174] The panel portion 320 may protrude further forward than the display module 21. As another embodiment, the panel portion 320 may also be configured such that its front surface is on the same plane as the front surface of the display module 21, or is located further rearward than the front surface of the display module 21, without protruding relative to the display module 21.

[0175] The panel portion 320 can be formed into a rod shape that is generally long and arranged along the side of the door 20 in its length direction. The panel portion 320 can guide the flow direction of the air discharged from the first outlet 123. For example, the panel portion 320 can change the flow direction of the air discharged from the first outlet 123 to the downward direction.

[0176] For this purpose, the panel portion 320 can be positioned in front of the first row of outlets 123. The panel portion 320 can be configured to overlap with the first row of outlets 123 in the front-rear direction. Air flowing inside the door 20 can be discharged in the front direction of the door 20 through the first row of outlets 123 located at the upper part of the door 20.

[0177] At this time, the panel 320 blocks the front of the first outlet 123, and the air discharged from the first outlet is blocked by the panel 320, so that the flow direction can be changed from the front direction of the door 20 to the downward direction.

[0178] Furthermore, the lower end of the panel portion 320 can be configured to protrude further downward than the lower end of the first outlet 123. With this structure, the air discharged from the first outlet 123 collides with the panel portion 320 and is guided by the panel portion 320, thereby changing the flow path downward.

[0179] The air discharged from the first outlet 123 in the forward direction can flow downward through the panel 320.

[0180] Air discharged forward from the first outlet 123 collides with the back of the panel 320, thereby changing its direction and flowing towards the open lower portion between the panel 320 and the first outlet 123. Furthermore, since the lower end of the panel 320 protrudes further downward than the lower end of the first outlet 123, air can be guided by the lower end of the panel 320 and then continue to flow downward towards the door 20 for a period of time after leaving the door 20.

[0181] Air forced to flow by the fan 152 can flow in from the inlet 141 and flow downwards into the fan 152. It then flows along the front-back direction of the door 20 through the fan 152 and splits in the vertical direction in front of the air guide 140. Part of the air flows upwards into the door 20 and is discharged from the first outlet 123, while the other part flows downwards into the door 20 and is discharged from the second outlet 124.

[0182] At this time, the air discharged from the first row outlet 123 is guided by the panel portion 320 to flow downwards, so that at least a portion can contact the front of the display portion 110. In addition, at least a portion of the air discharged from the second row outlet 124 can flow towards the front of the door 20.

[0183] The air discharged from the second outlet 124 flows in front of the door 20, thereby preventing the oil vapor and other foreign objects rising from the heating cooking device located below the cooking equipment from adhering to the air curtain on the front of the display unit 110.

[0184] Similar to the air discharged from the second outlet 124, the air discharged from the first outlet 123 can form an air curtain to prevent oil vapor and the like from adhering to the front of the display unit 110.

[0185] In addition, the airflow direction discharged from the first row outlet 123 can be changed by the panel 320 to be discharged towards the lower side of the door 20, so that at least a part of it can come into contact with the front of the display 110.

[0186] With this structure, the air discharged from the first row outlet 123 can directly contact the front of the display unit 110 to cool the front of the display unit 110. Therefore, both the front and back of the display unit 110 are cooled by air, thereby significantly improving cooling efficiency compared to the case where only the back of the display unit 110 is cooled.

[0187] Figure 18 This is an exploded perspective view showing an inner panel 130 and an air guide 140 according to one embodiment. Figure 19 This is an enlarged view of a portion of the air guide 140.

[0188] The air guide 140 of the embodiment may include a guide rib 143 protruding from the inner panel 130 at its upper part. The guide rib 143 can guide the flow direction of the incoming air.

[0189] The guide rib 143 can guide the flow of air flowing into the air guide 140 through the first through hole 121 of the outer panel 120 and the inlet 141 of the air guide 140.

[0190] The guide rib 143 extends generally downward from the upper part of the air guide 140. Thus, the guide rib 143 guides the air flowing into the air guide 140 to flow smoothly towards the exhaust port 142 where the blower fan 152 is located. Of course, this forced airflow is generated by the operation of the blower fan 152.

[0191] The guide rib 143 can be formed to extend from the edge of the inlet 141. By positioning the guide rib 143 adjacent to the inlet 141 where air flows into the air guide 140, it is possible to effectively suppress the formation of vortexes in the air guide 140 interior space where the cross-sectional area of ​​the air flowing in from the inlet 141, which has a smaller cross-sectional area compared to the interior space of the air guide 140, which has a suddenly large increase in cross-sectional area.

[0192] The inlet 141 can be arranged in a pair, spaced apart from each other along the lateral direction of the air guide 140. Correspondingly, guide ribs 143 can be formed by extending from the inner edge of the edge of each inlet of the pair of inlets 141, respectively, to form a pair.

[0193] Therefore, a pair of guide ribs 143 can effectively guide the flow of air flowing in from each of the pair of inlets 141.

[0194] A pair of guide ribs 143 can be configured to be symmetrical about the center of the air guide 140. A pair of inlet inlets 141 can be formed to be symmetrical about the air supply fan 152 disposed at the center of the air guide 140.

[0195] Therefore, the pair of guide ribs 143 can also be formed symmetrically with respect to the air supply fan 152 located at the center of the air guide 140. As a result, the air flowing in from the pair of inlets 141 can flow symmetrically and uniformly inside the air guide 140.

[0196] The air guide 140 may include an upper protruding wall 144 connected to the inner edge of each of a pair of inlets 141. The upper protruding wall 144 may be formed protruding toward the inner panel 130 at the upper end of the air guide 140.

[0197] The upper protruding wall 144 can be combined with the inner panel 130 to seal the upper end of the flow space inside the air guide 140. Of course, an inlet 141 is formed at the edge of the upper protruding wall 144, so that air can flow into the flow space inside the air guide 140 through the inlet 141.

[0198] The guide rib 143 can be formed to extend from the upper protruding wall 144. Therefore, the guide rib 143 can be positioned at the boundary between the upper protruding wall 144 and the inlet 141.

[0199] With this structure, the air flowing in from the inlet 141 in the downward direction and the air flowing along the side of the air guide 140 at the top of the air guide 140 can be prevented from meeting each other and forming a vortex.

[0200] That is, when air flows in different directions meet each other, a vortex is formed, and the vortex reduces the flow velocity, which may reduce the air flow rate inside the air guide 140.

[0201] In this embodiment, the guide rib 143 effectively reduces the formation of vortices by preventing air from flowing in different directions from meeting each other, thus increasing the airflow inside the air guide 140.

[0202] Figure 20 This is the front view of the air guide 140. Figure 20 In the image, the direction of airflow is indicated by arrows at the location adjacent to the guide rib 143. The length direction of the guide rib 143 can be arranged in a direction inclined relative to the vertical and lateral directions of the air guide 140.

[0203] Specifically, the guide rib 143 can be configured to extend downward from the upper protruding wall 144 toward the lower side of the air guide 140 and approach the outer edge of the air guide 140.

[0204] That is, the guide rib 143 can be obliquely formed so that it approaches the outer side of the air guide 140 as it extends downward from the air guide 140.

[0205] If the blower fan 152 is activated, air can be forced to flow into the air guide 140 through the inlet 141 and flow there. Additionally, air can be exhausted forward of the air guide 140 through the blower fan 152 and the exhaust port 142.

[0206] As the fan 152 rotates, a portion of the air can rise inside the air guide 140 toward the upper side of the fan 152 and collide with the upper protruding wall 144, thereby flowing laterally in the upper part of the air guide 140.

[0207] At this time, the guide rib 143 located at the boundary between the inlet 141 and the upper protrusion can be configured to at least partially prevent the lateral airflow of air formed on the upper part of the air guide 140 and the lower airflow of air formed on the inlet 141 from mixing with each other.

[0208] Therefore, it can effectively suppress the mixing of lateral and downward airflow to form vortices.

[0209] When vortices are formed, the air velocity inside the air guide 140 slows down and the amount of airflow decreases. As a result, the cooling effect of the forced airflow on the display section 110 and the internal components of the door 20 may be reduced.

[0210] In this embodiment, the aforementioned structure significantly suppresses the generation of eddies at the boundary between the inlet 141 and the upper protrusion. Therefore, compared to a structure without the guide ribs 143, the cooling effect of the door 20 can be improved.

[0211] On the other hand, since the guide rib 143 is inclined downwards and approaches the outer edge of the air guide 140, the lateral airflow formed in the upper part of the air guide 140 collides with the guide rib 143 and flows downwards. That is, in the upper part of the air guide 140, the lateral airflow can change its flow direction along the inclined direction of the guide rib 143 and flow downwards.

[0212] With this structure, the lateral airflow will not rise or stagnate at the position adjacent to the guide rib 143, thereby effectively suppressing the formation of vortices due to the rise or stagnation of air.

[0213] By suppressing the formation of eddies, the air velocity and flow rate inside the air guide 140 are increased, thereby improving the cooling effect of the door 20.

[0214] Figure 21 This is a diagram showing the results of a simulation of the airflow inside the inner panel 130 and the air guide 140. To illustrate this clearly, in... Figure 21 The cross-section of the air guide 140 is shown in the figure.

[0215] like Figure 21 As shown, air forced to flow by the air supply fan 152 can flow from the inlet 141 towards the lower side of the door 20 and into the air supply fan 152. Additionally, air can pass through the air supply fan 152 and the exhaust port 142 along the front-to-back direction of the door 20.

[0216] like Figure 21As shown, it can be confirmed that, as described above, vortices are significantly suppressed in the flow space inside the air guide 140, allowing air to flow smoothly. Therefore, it can be clearly confirmed that vortices are suppressed by the guide rib 143, airflow is smooth, and thus air velocity and flow rate increase.

[0217] Figure 22 This is a diagram showing the results of a simulation of the airflow inside the outer panel 120.

[0218] like Figure 21 As shown, the air discharged towards the front of the air guide 140 via the fan 152 and exhaust port 142 is split vertically in front of the air guide 140, so that a portion of the air can flow towards the upper side of the door 20 and be discharged from the first outlet 123. Another portion of the air can flow towards the lower side of the door 20 and be discharged from the second outlet 124.

[0219] It can be confirmed that the airflow generally exhibits a curl shape due to the rotation of the blower fan 152. However, it can be confirmed that, unrelated to this, the air is smoothly discharged from the first outlet 123 and the second outlet 124.

[0220] As described above, the present invention has been illustrated with reference to the accompanying drawings. However, the present invention is not limited to the embodiments and drawings disclosed in this specification, and it is obvious that those skilled in the art can make various modifications within the scope of the technical concept of the present invention. Furthermore, even when the embodiments of the present invention are described above, the effects of the configuration according to the present invention are not explicitly stated, but the effects that can be predicted through the corresponding configuration should be recognized.
