Description

Technical Field

[0001] This invention relates to the field of household appliance technology, and more specifically, to a cooking appliance. Background Technology

[0002] Currently, the cooking cavity of cooking appliances is at a high temperature when they are working, which leads to a high ambient temperature in the housing and power board components.

[0003] In related technologies, heat insulation is usually achieved by increasing the distance between the shell and the cooking cavity, and filling the space between the shell and the cooking cavity with heat insulation material. However, this method results in a larger overall size and heavier product for the cooking appliance. Summary of the Invention

[0004] The present invention aims to solve at least one of the technical problems existing in the prior art or related art.

[0005] Therefore, the present invention provides a cooking utensil.

[0006] In view of this, the present invention proposes a cooking appliance, comprising: a cooking part having an opening; a housing disposed outside the cooking part and enclosing a channel with the cooking part, the channel having a first air outlet, the housing having a first air inlet located on the side of the housing away from the opening; a fan disposed inside the housing for supplying air into the channel; and a control box disposed inside the housing, located outside the cooking part, the control box having a second air inlet and a second air outlet, the second air inlet being connected to the first air inlet, and the second air outlet being connected to the channel via the fan.

[0007] The cooking appliance provided by this invention includes a cooking unit, a housing, a control box, and a fan. The cooking unit is disposed within the housing and forms a channel enclosed by the housing. The channel has a first air outlet, and the housing has a first air inlet on the side opposite to the outlet. The control box is disposed within the housing and is connected to the first air inlet via a second air inlet and to the channel via a second air outlet. Thus, when the fan is turned on, a negative pressure environment is created inside the control box. Air from outside the cooking appliance enters the housing through the first air inlet, then enters the control box through the second air inlet, then enters the fan through the second air outlet of the control box, then enters the channel through the fan, and finally flows out through the first air outlet. The airflow can both remove heat from the control box, achieving heat dissipation for the electrical components inside the control box, and remove heat from the channel, preventing the housing from overheating. This improves the heat dissipation effect of the cooking appliance, eliminating the need to increase the distance between the housing and the cooking unit to reduce the housing temperature, thereby solving the problem of the cooking appliance being too large.

[0008] Understandably, the enclosed channel between the cooking unit and the housing creates a gap, reducing heat transfer from the cooking unit to the housing. Simultaneously, airflow through the channel carries away heat, lowering the ambient temperature of the housing. Furthermore, the first air inlet is positioned on the side of the housing furthest from the opening along a first direction (e.g., the front-to-back direction of the housing). This placement at the rear of the housing minimizes damage to the cookware's appearance, enhancing its aesthetics, and also prevents children from accidentally touching the control box with sharp objects inserted into the first air inlet.

[0009] The cooking appliance provided by the present invention may also have the following additional technical features:

[0010] In some embodiments, the channel is optionally located at the top of the cooking section in the vertical direction, and the first air outlet is located on the side of the channel near the opening.

[0011] In this embodiment, the channel is located at the top of the cooking unit in the vertical direction, so that the channel is away from the heating component at the bottom of the cooking unit. The first air outlet is located on the side of the channel near the opening, which can avoid the first air outlet being blocked by other structures and ensure the heat dissipation effect.

[0012] In some embodiments, the control box is optionally located on the side of the cooking section away from the outlet, and the fan is located between the control box and the channel.

[0013] In this embodiment, the control box is located on the side of the cooking section away from the opening and between the cooking section and the housing. This reduces the space occupied by the control box in the height and width directions of the cooking appliance, facilitating its storage. Simultaneously, the fan is located between the control box and the channel, and the first air inlet is located on the side of the housing away from the opening along the first direction. This brings the control box closer to the first air inlet, shortening the path for external cold air to enter the control box and improving heat dissipation for the electrical components inside the control box.

[0014] In some embodiments, the fan is optionally mounted on the control box and located at the very top of the control box.

[0015] In this embodiment, the fan is installed in the control box, so that the fan and the control box can be assembled and then installed in the housing, which reduces the installation difficulty of the fan and improves the assembly effect.

[0016] In some embodiments, an elastic element may be provided between the fan and the control box, and the fan contacts the control box through the elastic element.

[0017] In this embodiment, the fan and control box are connected by an elastic element, which can greatly reduce the noise of the fan during operation. At the same time, this arrangement can also improve the sealing performance between the second air outlet and the fan, preventing air leakage and thus improving air delivery efficiency.

[0018] In some embodiments, the elastic element may optionally include a silicone element or a rubber element; and / or the fan may include a cross-flow fan.

[0019] In this embodiment, the elastic element can be made of elastic materials such as silicone or rubber. The fan includes a cross-flow fan, which has a larger air volume, thus improving the heat dissipation efficiency within the channel and control box.

[0020] In some embodiments, the control box may optionally include: a box body, with a second air outlet located at the top of the box body in the vertical direction; a cover plate, which is fastened to the box body and surrounds the air duct with the box body, the cover plate being located on the side of the box body away from the outlet, and a second air inlet located on the cover plate; and electrical components located within the air duct.

[0021] In this embodiment, the control box includes a box body, a cover plate, and electrical components. The cover plate is fastened to the side of the box body away from the opening, thereby enclosing the air duct with the box body. A second air inlet is provided on the cover plate, and a second air outlet is provided at the top of the box body in the vertical direction. Thus, airflow enters the air duct through the second air inlet to cool the electrical components in the air duct.

[0022] In some embodiments, the cover plate may optionally be fitted to the portion of the housing where the first air inlet is located.

[0023] In this embodiment, the cover plate is fitted to the housing, so that the second air inlet on the cover plate fits into the first air inlet on the housing, thereby increasing the airflow into the air duct.

[0024] In some embodiments, the box body may optionally include a box body and an extension connected to each other; a cover is fastened to the side of the box body away from the opening, the extension is located at one end of the box body in the vertical direction near the bottom of the housing, and the extension contacts the bottom of the housing, the box body, the extension and the cover together enclose the air outlet duct.

[0025] In this embodiment, the box includes a main body and an extension connected to each other. The main body is used to install electrical components, and the cover is fastened to the main body to improve the safety performance of the electrical components. The extension is located at one end of the main body in the vertical direction near the bottom of the housing and extends to the bottom of the housing. This allows the end of the extension to abut against the bottom of the housing, preventing heat from the cooking unit from being transferred to the control box from the bottom. This helps to reduce the ambient temperature of the control box and improve the working performance of the electrical components.

[0026] In some embodiments, optionally, the end of the extension away from the box body is sealed to the bottom of the housing.

[0027] In this embodiment, the end of the extension away from the box body is sealed to the bottom of the shell, so that the extension isolates the cooking part from the air duct, preventing the heat generated by the cooking part during operation from being drawn into the air duct by the fan and causing the temperature of the electrical components to rise.

[0028] In some embodiments, the housing may optionally have heat dissipation holes at the bottom in the vertical direction, with the heat dissipation holes located on the side of the extension away from the first air inlet.

[0029] In this embodiment, the housing has heat dissipation holes at the bottom in the vertical direction. The heat dissipation holes are used to achieve natural heat dissipation of the cooking unit. The heat dissipation holes are located on the side of the extension away from the first air inlet. That is, the heat dissipation holes and the first air inlet are located on the two sides of the extension, respectively. The extension separates the heat dissipation holes and the air duct to prevent the heat from the cooking unit from entering the control box.

[0030] In some embodiments, optionally, the bottom of the cover plate along the vertical direction and the extension enclose an air duct inlet, wherein there are multiple first air inlets, among which a portion of the first air inlets are connected to the air duct inlet and another portion of the first air inlets are connected to the second air inlet; and / or the end of the extension away from the box body along the vertical direction is open; and / or the extension and the box body are an integral structure.

[0031] In this embodiment, the bottom of the cover plate along the vertical direction and the extension form an air duct inlet, so that a portion of the first air inlet communicates with the air duct inlet, and another portion of the first air inlet communicates with the second air inlet. Thus, some airflow enters the air duct from the first air inlet through the second air inlet, and another portion enters the air duct inlet from the first air inlet and then enters the air duct, increasing the airflow volume within the air duct. Optionally, the end of the extension away from the box body along the vertical direction is open, reducing material usage and improving the seal between the extension and the bottom of the shell, preventing hot air from the cooking section from flowing into the control box. Optionally, the box body and the extension are an integral structure, improving the connection strength between the box body and the extension.

[0032] In some embodiments, the cooking unit may optionally include: a cooking cavity including an opening; and a heat insulation component surrounding the outer surface of the cooking cavity and disposed to avoid the opening, at least a portion of the heat insulation component enclosing a channel with the housing.

[0033] In this embodiment, the cooking unit includes a cooking cavity and a heat insulation component. The heat insulation component is disposed between the cooking cavity and the housing, providing heat insulation for the cooking cavity and reducing the heat transferred from the cooking cavity to the housing. Simultaneously, at least a portion of the heat insulation component and the housing enclose a channel, creating air insulation between the heat insulation component and the housing, further enhancing the heat insulation effect. Furthermore, in the cooking appliance proposed in this application, when the fan is turned on, airflow enters the housing through the first air inlet, then enters the control box, and finally enters the channel. This effectively removes heat transferred from the cooking cavity to the channel, improving the heat dissipation effect of the cooking appliance, reducing the temperature of the housing, and extending the service life of the cooking appliance.

[0034] In some embodiments, the cooking section may optionally include: a baffle connected to the cooking cavity and surrounding the periphery of the opening, the baffle being connected to the housing, and a first air outlet being located at the top of the baffle.

[0035] In this embodiment, the cooking unit also includes a baffle plate, which surrounds the periphery of the opening and is connected to the housing, realizing the assembly of the cooking cavity and the housing. The first air outlet is located on the top of the baffle plate, realizing air intake from the back and air exhaust from the front, thus improving the heat dissipation effect of the channel.

[0036] In some embodiments, the housing may optionally include: a base plate located at the bottom of the cooking section; an outer cover covering the outside of the cooking section and connected to the base plate; a first back plate located on the side of the cooking section away from the opening; a second back plate located on the side of the first back plate away from the cooking section; and a control box and a fan located between the first back plate and the second back plate.

[0037] In this embodiment, the housing includes a bottom plate, an outer cover, a first back plate, and a second back plate. The bottom plate is located at the bottom of the cooking section, the outer cover is placed on the outside of the cooking section and connected to the bottom plate, the first back plate and the second back plate are located on the side of the cooking section away from the opening, and the second back plate is located on the side of the first back plate away from the opening. The control box and the fan are arranged between the first back plate and the second back plate, so that the ambient temperature at the location of the control box and the fan is low, and that the control box and the fan do not occupy the space in the height direction and the width direction of the cooking appliance, thereby facilitating the storage of the cooking appliance.

[0049] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0050] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the scope of protection of the invention is not limited to the specific embodiments disclosed below.

[0051] The following reference Figures 1 to 7 A cooking appliance is described according to some embodiments of the present invention.

[0052] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, according to an embodiment of the present invention, a cooking appliance is provided, comprising: a cooking part 1, the cooking part 1 having an opening 120; a housing 2, disposed on the outside of the cooking part 1, and enclosing a channel 3 with the cooking part 1, the channel 3 having a first air outlet 30, the housing 2 having a first air inlet 20, the first air inlet 20 being located on the side of the housing 2 away from the opening 120; a fan 5, disposed inside the housing 2, for supplying air into the channel 3; and a control box 4, disposed inside the housing 2, located on the outside of the cooking part 1, the control box 4 having a second air inlet 40 and a second air outlet 42, the second air inlet 40 communicating with the first air inlet 20, and the second air outlet 42 being connected to the channel 3 through the fan 5.

[0053] The cooking appliance provided by this invention includes a cooking unit 1, a housing 2, a control box 4, and a fan 5. The cooking unit 1 is disposed inside the housing 2 and encloses a channel 3 with the housing 44. The channel 3 is provided with a first air outlet 30. The housing 2 is provided with a first air inlet 20 on the side away from the opening 120 along a first direction. The control box 4 is disposed inside the housing 2 and is connected to the first air inlet 20 through a second air inlet 40 and to the channel 3 through a second air outlet 42. Thus, when the fan 5 is turned on, a negative pressure environment is formed inside the control box 4, and air from outside the cooking appliance is drawn in through the first air inlet 20. The airflow enters the housing 2, then enters the control box 4 through the second air inlet 40, then enters the fan 5 through the second air outlet 42 of the control box 4, then enters the channel 3 through the fan 5, and finally flows out through the first air outlet 30. The airflow can both remove the heat from the control box 4, thus dissipating the heat of the electrical components 48 inside the control box 4, and remove the heat from the channel 3, preventing the housing 2 from overheating. This improves the heat dissipation effect of the cooking appliance, eliminating the need to increase the distance between the housing 2 and the cooking part 1 to reduce the temperature of the housing 2, thereby solving the problem of the cooking appliance being too large.

[0054] Understandably, the passage 3 formed between the cooking section 1 and the housing 2 creates a certain gap between them, thereby reducing the heat transferred from the cooking section 1 to the housing 2. Simultaneously, as airflow passes through the passage 3, it also carries away heat from within the passage 3, lowering the ambient temperature of the housing 2. Furthermore, the first air inlet 20 is located on the side of the housing 2 away from the opening 120 along a first direction (e.g., the front-to-back direction of the housing 2). This placement of the first air inlet 20 on the rear side of the housing 2 reduces potential damage to the appearance of the cooking appliance, enhancing its aesthetics. It also prevents children from accidentally touching the control box 4 by inserting sharp objects into the first air inlet 20.

[0055] It should be noted that, Figure 1 , Figure 2 and Figure 3 The arrows in the diagram indicate the direction of airflow.

[0056] In some embodiments, the channel 3 is optionally located at the top of the cooking section 1 in the vertical direction, and the first air outlet 30 is located on the side of the channel 3 near the opening 120.

[0057] In this embodiment, the channel 3 is located at the top of the cooking section 1 in the vertical direction, so that the channel 3 is away from the heating component at the bottom of the cooking section 1. The first air outlet 30 is located on the side of the channel 3 near the opening 120, which can prevent the first air outlet 30 from being blocked by other structures and ensure the heat dissipation effect.

[0058] like Figure 1 As shown, in some embodiments, optionally, the control box 4 is located on the side of the cooking section 1 away from the outlet 120, and the fan 5 is located between the control box 4 and the channel 3.

[0059] In this embodiment, the control box 4 is located on the side of the cooking section 1 away from the opening 120 and between the cooking section 1 and the housing 2. This reduces the space occupied by the control box 4 in the height and width directions of the cooking appliance, making it easier to store the cooking appliance. Meanwhile, the fan 5 is located between the control box 4 and the channel 3, and the first air inlet 20 is located on the side of the housing 2 away from the opening 120 along the first direction. This brings the control box 4 closer to the first air inlet 20, thereby shortening the path for external cold air to enter the control box 4 and improving the heat dissipation effect on the electrical components 48 inside the control box 4.

[0060] In some embodiments, the fan 5 is optionally mounted on the control box 4 and located on top of the control box 4.

[0061] In this embodiment, the fan 5 is installed in the control box 4, so that the fan 5 and the control box 4 can be assembled and then installed in the housing 2, which reduces the installation difficulty of the fan 5 and improves the assembly effect.

[0062] like Figure 4 As shown, in some embodiments, optionally, an elastic element 6 is provided between the fan 5 and the control box 4, and the fan 5 contacts the control box 4 through the elastic element 6.

[0063] In this embodiment, the fan 5 and the control box 4 are connected by an elastic element 6, which can greatly reduce the noise of the fan 5 during operation. At the same time, this arrangement can also improve the sealing performance between the second air outlet 42 and the fan 5, prevent air leakage, and thus improve the air delivery efficiency.

[0064] In some embodiments, the elastic element 6 may optionally include a silicone element or a rubber element; and / or the fan 5 may include a cross-flow fan.

[0065] In this embodiment, the elastic element 6 can be made of elastic materials such as silicone or rubber. The fan 5 includes a cross-flow fan, which has a large air volume, thus improving the heat dissipation efficiency within the channel 3 and control box 4.

[0066] like Figure 2 , Figure 4 and Figure 5 As shown, in some embodiments, optionally, the control box 4 includes: a box body 44, with a second air outlet 42 located at the top of the box body 44 in the vertical direction; a cover plate 46, which is fastened to the box body 44 and surrounds the air outlet 49 with the box body 44, the cover plate 46 being located on the side of the box body 44 away from the outlet 120, and a second air inlet 40 being located on the cover plate 46; and an electrical component 48, which is located inside the air outlet 49.

[0067] In this embodiment, the control box 4 includes a box body 44, a cover plate 46, and electrical components 48. The cover plate 46 is fastened to the side of the box body 44 away from the opening 120, thereby enclosing the air duct 49 with the box body 44. A second air inlet 40 is provided on the cover plate 46, and a second air outlet 42 is provided on the top of the box body 44 in the vertical direction. Thus, the airflow enters the air duct 49 through the second air inlet 40, thereby cooling the electrical components 48 in the air duct 49.

[0068] Optionally, electrical components 48 include power boards, circuit boards, etc.

[0069] Optionally, the vertical direction refers to the up-down direction of the cooking utensil.

[0070] In some embodiments, the cover plate 46 may optionally be fitted to the portion of the housing 2 where the first air inlet 20 is provided.

[0071] In this embodiment, the cover plate 46 is attached to the housing 2, so that the second air inlet 40 on the cover plate 46 is attached to the first air inlet 20 on the housing 2, thereby increasing the airflow into the air duct 49.

[0072] like Figure 4 and Figure 5 As shown, in some embodiments, optionally, the box body 44 includes a box body 440 and an extension 442 that are connected to each other; the cover plate 46 is fastened to the box body 440, the extension 442 is located at one end of the box body 440 in the vertical direction near the bottom of the housing 2, and the extension 442 contacts the bottom of the housing 2, and the box body 440, the extension 442 and the cover plate 46 surround the air outlet duct 49.

[0073] In this embodiment, the housing 44 includes a housing body 440 and an extension 442 connected to each other. The housing body 440 is used to install electrical components 48, and the cover plate 46 is fastened to the housing body 440 to improve the safety performance of the electrical components 48. The extension 442 is located at one end of the housing body 440 in the vertical direction near the bottom of the housing 2 and extends to the bottom of the housing 2, so that the end of the extension 442 abuts against the bottom of the housing 2, preventing the heat of the cooking unit 1 from being transferred from the bottom to the control box 4, which helps to reduce the ambient temperature of the control box 4 and improve the working performance of the electrical components 48.

[0074] In some embodiments, optionally, one end of the extension 442 away from the box body 440 is sealed to the bottom of the housing 2.

[0075] In this embodiment, the end of the extension 442 away from the box body 440 is sealed to the bottom of the shell 2, so that the extension 442 isolates the cooking part 1 from the air duct 49, preventing the heat generated by the cooking part 1 during operation from being drawn into the air duct 49 by the fan and causing the temperature of the electrical components 48 to rise.

[0076] In some embodiments, the housing 2 may optionally have a heat dissipation hole 220 at the bottom in the vertical direction, and the heat dissipation hole 220 is located on the side of the extension 442 away from the first air inlet 20.

[0077] In this embodiment, the housing 2 is provided with heat dissipation holes 220 at the bottom of the vertical direction. The heat dissipation holes 220 are used to achieve natural heat dissipation of the cooking unit 1. The heat dissipation holes 220 are located on the side of the extension 442 away from the first air inlet 20. That is, the heat dissipation holes 220 and the first air inlet 20 are located on both sides of the extension 442. The extension 442 separates the heat dissipation holes 220 and the air duct 49 to prevent the heat of the cooking unit 1 from entering the control box 4.

[0078] like Figure 4 and Figure 5 As shown, in some embodiments, optionally, the bottom of the cover plate 46 and the extension 442 in the vertical direction enclose an air duct inlet 47, wherein there are multiple first air inlets 20, among which a portion of the first air inlets 20 are connected to the air duct inlet 47, and another portion of the first air inlets 20 are connected to the second air inlet 40; and / or the end of the extension 442 away from the box body 440 in the vertical direction is open; and / or the extension 442 and the box body 440 are an integral structure.

[0079] In this embodiment, the bottom of the cover plate 46 along the vertical direction and the extension 442 enclose an air duct inlet 47, so that a portion of the first air inlet 20 communicates with the air duct inlet 47, and another portion of the first air inlet 20 communicates with the second air inlet 40. Thus, a portion of the airflow enters the air duct 49 from the first air inlet 20 through the second air inlet 40, and another portion of the airflow enters the air duct inlet 47 from the first air inlet 20 and then enters the air duct 49, increasing the airflow volume within the air duct 49. Optionally, the extension 442 is open at one end along the vertical direction away from the box body 440, reducing material usage and improving the seal between the extension 442 and the bottom of the shell 2, preventing hot air from the cooking section 1 from flowing into the control box 4. Optionally, the extension 442 and the box body 440 are an integral structure, improving the connection strength between the box body 440 and the extension 442.

[0080] like Figure 1 , Figure 2 and Figure 6 As shown, in some embodiments, optionally, the cooking part 1 includes: a cooking cavity 12, the cooking cavity 12 including an opening 120; a heat insulation component 14, which surrounds the outer surface of the cooking cavity 12 and is disposed to avoid the opening 120, and at least a portion of the heat insulation component 14 and the housing 2 enclose a channel 3.

[0081] In this embodiment, the cooking unit 1 includes a cooking cavity 12 and a heat insulation component 14. The heat insulation component 14 is disposed between the cooking cavity 12 and the housing 2, providing heat insulation for the cooking cavity 12 and reducing the heat transferred from the cooking cavity 12 to the housing 2. Simultaneously, at least a portion of the heat insulation component 14 and the housing 2 enclose a channel 3, creating air insulation between the heat insulation component 14 and the housing 2, further enhancing the heat insulation effect. Furthermore, in the cooking appliance proposed in this application, when the fan 5 is turned on, the airflow enters the housing 2 through the first air inlet 20, enters the control box 4, and then enters the channel 3. This can carry away the heat transferred from the cooking cavity 12 to the channel 3, improving the heat dissipation effect of the cooking appliance, reducing the temperature of the housing 2, and extending the service life of the cooking appliance.

[0082] Optionally, the heat insulation component 14 includes a heat insulation plate, which is spaced apart from the housing 2 by a bracket, thereby reducing the contact area between the heat insulation plate and the housing 2, which in turn helps to reduce the heat transferred from the cooking cavity 12 to the housing 2.

[0083] Optionally, the heat insulation plate and the cooking cavity 12 are also spaced apart by a bracket, which reduces the contact area between the heat insulation plate and the cooking cavity 12, thereby helping to reduce the heat transferred from the cooking cavity 12 to the heat insulation plate.

[0084] Optionally, the heat insulation plate surrounds the top and bottom of the cooking cavity 12 in the vertical direction, the side away from the opening 120 in the first direction, and both sides in the second direction, so that the top and bottom of the cooking cavity 12 in the vertical direction, the side away from the opening 120 in the first direction, and both sides in the second direction all have heat insulation gaps, thereby improving the heat insulation effect.

[0085] Optionally, along the vertical direction, the heat insulation plate located at the top of the cooking cavity 12 and the shell 2 enclose a channel 3.

[0086] Optionally, heat insulation cotton is provided between the heat insulation plate and the outer surface of the cooking cavity 12. The heat insulation cotton is wrapped around the top and bottom of the cooking cavity 12 in the vertical direction, the side away from the opening 120 in the first direction, and both sides in the second direction, so as to achieve comprehensive heat insulation of the cooking cavity 12 and improve the heat insulation effect.

[0095] Optionally, the first backplate 26 is located on the side of the thermal insulation assembly 14 facing away from the outlet 120 along the first direction.

[0096] Optionally, the cooking section 1 also includes a heating assembly for supplying heat to the cooking cavity 12.

[0097] Optionally, the cooking appliance includes any one of an oven, a steam oven, a steam oven, a microwave oven, or a microwave steam oven.

[0098] According to one embodiment of this application, optionally, under the action of a cross-flow fan, cold air enters from the rear of the outer rear panel (e.g., the second back panel 28), passes sequentially through the control box 4, the cross-flow fan, the channel 3 between the heat insulation panel assembly (e.g., heat insulation assembly 14) and the outer shell (e.g., shell 2), the front panel (e.g., baffle 16), and finally exits from the gap between the front panel and the oven door (e.g., door body). This arrangement has high heat dissipation efficiency and can effectively reduce the distance between the cavity and the outer shell, thereby solving the problems of large size and bulky products in current high-temperature cooking equipment.

[0099] Optionally, the outer rear panel is provided with an air inlet (e.g., a first air inlet 20), through which cold air enters.

[0100] Optionally, the control box 4 consists of a base (e.g., box body 44), a cover plate 46, and a power board. The base and cover plate 46 form an air duct 49. A small hole (e.g., a second air inlet 40) is opened at the rear of the cover plate 46, allowing air to enter from the bottom and rear of the cover plate 46. The second air inlet 40 is fitted to the first air inlet 20. The bottom of the air duct 49 is fitted to the base plate 22, preventing hot air from entering from the front section of the bottom, thus creating a low-temperature environment for the control box 4. A cross-flow fan is installed at the top of the air duct 49. A silicone pad (e.g., an elastic element 6) is installed between the top of the air duct 49 and the cross-flow fan to ensure the airtightness of the air duct 49 and reduce vibration, thereby improving the efficiency of the air duct 49 and reducing noise.

[0101] Optionally, the front panel of the cooking section 1 has an air outlet (e.g., a first air outlet 30), from which hot air is exhausted by a fan.

[0102] Optionally, the base plate 22 has heat dissipation holes 220, which can dissipate heat from the bottom of the cooking section 1.

[0103] The cooking appliance proposed in this application reduces the ambient temperature of the outer shell surface and power board of the high-temperature cooking equipment, solves the main technical difficulties in the high-temperature cooking equipment industry, and has high heat dissipation efficiency, which can effectively reduce the distance between the cooking cavity 12 and the outer shell, thereby solving the problems of large size and bulky products in the current high-temperature cooking equipment.
