Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of cooking electric appliances, in particular to a cooking appliance. BACKGROUND

[0002] In the field of high-temperature cooking equipment, for example, the cavity temperature of a pizza oven is often as high as 500 DEG C or above. How to effectively reduce the ambient temperature of the shell surface and power board assembly of high-temperature cooking equipment has been a technical problem faced by the industry. At present, the industry generally adopts the measure of increasing the distance between the shell and the cavity and filling thermal insulation material therebetween. However, this approach can only solve the heat dissipation problem to a certain extent, and inevitably leads to an increase in the size of the high-temperature cooking equipment, making the product bulky. This not only increases the occupied space of the equipment, but also brings many inconveniences to the handling and use.

[0003] Therefore, how to design a cooking appliance with efficient heat dissipation and compact structure has become a problem to be solved at present. SUMMARY

[0004] The utility model aims at least solves the problem such as the poor heat dissipation effect and big volume of cooking appliance.

[0005] To this end, the first aspect of the utility model provides a cooking appliance.

[0006] Therefore, the first aspect of the utility model provides a cooking appliance, which comprises a box body, a control box, an air inlet and a first heat dissipation channel and a second heat dissipation channel.

[0007] The cooking appliance provided by the utility model comprises a box body and a control box. The box body has a cooking cavity and a heat dissipation channel. The cooking cavity can cook food materials, and the heat dissipation channel can dissipate the temperature generated during cooking, avoiding the influence of high temperature on the control box, the box body and electronic elements in the control box. By arranging the first heat dissipation channel and the second heat dissipation channel with different directions, the utility model effectively guides the airflow to flow in the box body, achieving comprehensive and efficient heat dissipation. The air inlet is arranged at the bottom of the box body, which can fully utilize the characteristics of cold air sinking, so that the incoming airflow rapidly fills the second heat dissipation channel and smoothly flows through the first heat dissipation channel before being discharged, greatly improving the heat dissipation efficiency and ensuring the stable operation of the control box and other key components in a suitable temperature environment, prolonging the service life.

[0008] Meanwhile, the heat dissipation channels are arranged to dissipate heat, so that the outer wall of the box body and the cooking cavity are not arranged to be far apart, and thick heat insulation materials do not need to be filled between the cooking cavity and the outer wall of the box body to reduce the temperature outside the box body, so that the overall volume of the box body can be arranged to be smaller, more compact and light, space is saved, and the box body is convenient to carry and operate.

[0009] According to the cooking utensil provided by the utility model, the following additional technical features can also be provided:

[0010] In some embodiments, optionally, the first heat dissipation channel is arranged at the top of the cooking cavity, and the second heat dissipation channel is arranged at the side of the cooking cavity.

[0011] In these embodiments, the first heat dissipation channel can be arranged at the top of the cooking cavity, so that the heat dissipation of the high-temperature area at the top of the cooking cavity can be prioritized, the accumulation of heat at the top can be effectively avoided, and the stability and safety of the upper structure of the cooking utensil can be ensured. The second heat dissipation channel is arranged at the side of the cooking cavity, so that the temperature of the side of the cooking cavity can be reduced in a targeted manner, and the influence of the high temperature on the side on the surrounding components can be reduced. Meanwhile, the cooperation of the top and side heat dissipation channels enables the heat in the cooking cavity to be dissipated more uniformly and quickly, improves the overall heat dissipation efficiency, ensures that the temperature of each part of the cooking utensil remains within a reasonable range when the cooking utensil is working, and improves the reliability and service life of the equipment.

[0012] In some embodiments, optionally, the first heat dissipation channel is arranged in the horizontal direction, and the second heat dissipation channel is arranged in the height direction.

[0013] In these embodiments, the first heat dissipation channel is arranged in the horizontal direction, so that the airflow can flow through the key components uniformly in the horizontal direction, the heat in the horizontal direction can be quickly dissipated, and the uniform dissipation of heat in the horizontal plane can be ensured. The second heat dissipation channel is arranged in the height direction, which effectively utilizes the principle of upward movement of hot air and downward movement of cold air, promotes the natural convection of hot and cold air, enables the heat to be discharged upward more smoothly, and improves the efficiency and effect of heat dissipation. The cooperation of the two fully utilizes the space, forms a three-dimensional heat dissipation cycle, optimizes the temperature distribution inside the cooking utensil to the greatest extent, reduces the risk of local overheating, and ensures the stability and reliability of the equipment operation.

[0014] In some embodiments, optionally, the cooking utensil further comprises: an air outlet arranged in the box body and communicating with the first heat dissipation channel.

[0015] In these embodiments, the air outlet communicating with the first heat dissipation channel can timely and effectively discharge the hot air passing through the first heat dissipation channel from the box body, so that the hot air is prevented from staying in the box body, the speed of heat dissipation is accelerated, and a low-temperature environment in the box body is maintained.

[0016] In some embodiments, the air outlet may be located on the side of the housing.

[0017] In these embodiments, placing the air outlet on the side of the enclosure prevents the exhausted hot air from blowing directly onto the operator, improving safety and comfort. Hot air exhausted from the side can diffuse more quickly into the surrounding environment, reducing the accumulation of hot air near the enclosure and thus lowering the ambient temperature. Simultaneously, the side air outlet placement does not affect the front and top operating areas of the enclosure, ensuring the overall integrity and aesthetics of the cooking appliance.

[0018] In some embodiments, the housing may optionally include an outer shell and a cooking cavity having an opening. The cooking appliance may also include a door assembly disposed at the opening for opening or closing the opening. When the door assembly closes the opening, an exhaust gap is formed between the door assembly and the outer shell, and an air outlet is disposed at the exhaust gap.

[0019] In these embodiments, the housing includes an outer shell and a cooking cavity. The outer shell covers the cooking cavity, providing protection. The cooking cavity has an opening, allowing food to be placed into or removed through it. A door assembly can also be included to open or close the opening. When the door assembly is closed, an exhaust gap is formed between the door assembly and the outer shell. An air outlet is located at this exhaust gap, guiding gas from the first heat dissipation channel into it. By placing the air outlet at the exhaust gap, hot air from the first heat dissipation channel can be exhausted without exposing the outlet, improving the overall aesthetics of the cooking appliance. Furthermore, it prevents external dust and other impurities from entering the first heat dissipation channel through the air outlet.

[0020] In some embodiments, optionally, the exhaust gap is inclined upwards from inside the door assembly to outside the door assembly along the height direction of the housing.

[0021] In these embodiments, the exhaust gap is inclined upwards from the inside to the outside of the door assembly along the height direction of the enclosure. That is, the exhaust gap is inclined and slopes upwards from the inside to the outside of the door assembly. It is understood that when using cooking appliances, users usually stand directly in front of them, i.e., to one side of the door assembly. Therefore, by tilting the exhaust gap upwards from the inside to the outside of the door assembly, the hot air exhausted from the exhaust gap blows obliquely upwards, rather than directly towards the user, thus ensuring the user is not exposed to hot air, ensuring user safety, and improving the user experience.

[0022] In some embodiments, optionally, a heat dissipation channel is disposed between the housing and the cooking cavity, and the cooking appliance further includes a heat insulation component surrounding the cooking cavity, wherein the heat insulation component and the housing form a heat dissipation channel.

[0023] In these embodiments, to further reduce the outer shell temperature, a heat insulation component can be provided between the cooking cavity and the outer shell. This component provides insulation, further reducing the outer shell temperature. Specifically, the heat insulation component surrounds the cooking cavity, forming a heat dissipation channel with the outer shell. This allows the cooling fan to be positioned between the heat insulation component and the outer shell, reducing the requirements for the cooling fan and eliminating the need for a high-temperature resistant fan, thus lowering the cost of the cooling fan.

[0024] In some embodiments, the cooking appliance may optionally include a heat dissipation fan disposed within the heat dissipation channel and corresponding to the air inlet, for blowing air into the heat dissipation channel.

[0025] In these embodiments, in order to further accelerate airflow and improve heat dissipation, a cooling fan can be installed in the heat dissipation channel, with the cooling fan positioned corresponding to the air inlet. This allows the cooling fan to absorb more cool outside air, thereby improving the heat dissipation effect.

[0026] In some embodiments, the air inlet and the cooling fan may be positioned directly opposite each other, or the air inlet and the cooling fan may be positioned offset from each other.

[0027] In some embodiments, the cooling fan may be positioned at the end of the second cooling channel away from the first cooling channel.

[0028] In these embodiments, the cooling fan can be positioned at the end of the second heat dissipation channel furthest from the first heat dissipation channel. This allows for smoother airflow within the heat dissipation channel, enabling it to remove more heat and improve the cooling effect. Simultaneously, because the cooling fan is positioned at the end of the second heat dissipation channel furthest from the first, airflow will flow from that end towards the first heat dissipation channel. In other words, the airflow can pass through the entire second heat dissipation channel, thereby removing even more heat from within it.

[0029] In some embodiments, optionally, the control box is disposed in the second heat dissipation channel; the control box includes an air passage that extends in the same direction as the second heat dissipation channel, and at least a portion of the airflow in the second heat dissipation channel can flow through the air passage.

[0030] In these embodiments, by placing the control box within the second heat dissipation channel, at least a portion of the airflow entering from the air inlet can directly act on the air passage within the control box, thereby dissipating heat from the electronic components inside the control box. It is understood that since the air passage and the second heat dissipation channel extend in the same direction, the airflow direction is also the same, making it easier for airflow to enter the air passage.

[0031] In some embodiments, the cooling fan is optionally located outside the control box, and the air outlet of the cooling fan is positioned opposite to the air inlet of the air passage.

[0032] In these embodiments, by setting the air outlet of the cooling fan opposite to the air inlet of the air passage, most, or even all, of the airflow blown out by the cooling fan can flow through the air passage, thereby further improving the heat dissipation effect on the electronic components inside the control box.

[0033] In some embodiments, the cooling fan may be fixedly installed outside the control box, or it may be directly fixedly installed inside the second cooling channel.

[0034] In some embodiments, the control box may optionally include: a housing disposed in the second heat dissipation channel, an air passage disposed in the housing; a mounting plate disposed in the air passage; and a circuit board assembly disposed in the air passage and mounted on the mounting plate.

[0035] In these embodiments, the control box includes a housing, a mounting plate, and a circuit board assembly. The housing is disposed within a second heat dissipation channel, and an airflow channel is disposed on the housing. The mounting plate and the circuit board assembly are both disposed within the airflow channel, thus allowing heat dissipation for the circuit board assembly through the airflow channel.

[0036] Understandably, the air passage can be formed by directly opening air inlets and outlets on opposite sides of the box. In this way, airflow can enter the box through the air inlets and then exit through the air outlets, thus achieving heat dissipation for the circuit board components inside the box.

[0037] In some embodiments, the cooking appliance may optionally include at least one of a pizza oven, oven, grill, steamer, and microwave oven.

[0038] In some embodiments, the cooling fan may optionally include at least one of a cross-flow fan, an axial flow fan, and a mixed-flow fan.

[0039] Additional aspects and advantages of this invention will become apparent in the description that follows, or may be learned by practice of this invention. Attached Figure Description

[0045] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model 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.

[0046] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0047] The following reference Figure 1 and Figure 2 This invention describes a cooking appliance proposed according to some embodiments of the present invention.

[0048] According to an embodiment of the first aspect of the present invention, such as Figure 1 and Figure 2 As shown, the first aspect of this utility model discloses a cooking appliance 1, including a housing 10 and a control box 13. The housing 10 has a cooking cavity 102 and a heat dissipation channel 104, the heat dissipation channel 104 including a channel along a first direction ( Figure 2 The first heat dissipation channel 1042 (in the direction indicated by L) and the second heat dissipation channel 1042 (in the direction indicated by L) are arranged in the second direction. Figure 2The second heat dissipation channel 1044 is located in the direction indicated by H in the middle. The control box 13 is located in the heat dissipation channel 104. The air inlet 12 is located at the bottom of the housing 10 and communicates with the second heat dissipation channel 1044. One end of the second heat dissipation channel 1044 is connected to the air inlet 12, and the other end of the second heat dissipation channel 1044 is connected to the first heat dissipation channel 1042. The airflow entering through the air inlet 12 flows through the second heat dissipation channel 1044 and the first heat dissipation channel 1042 and then exits.

[0049] The cooking appliance 1 provided by this utility model includes a housing 10 and a control box 13. The housing 10 has a cooking cavity 102 and a heat dissipation channel 104. The cooking cavity 102 can cook food, and the heat dissipation channel 104 can dissipate the heat generated during cooking, preventing high temperatures from affecting the control box 13, the housing 10, and the electronic components inside the control box 13. This application effectively guides airflow within the housing 10 by setting a first heat dissipation channel 1042 and a second heat dissipation channel 1044 with different directions, achieving comprehensive and efficient heat dissipation. The air inlet 12 is located at the bottom of the housing 10, which fully utilizes the sinking characteristic of cold air, allowing the incoming airflow to quickly fill the second heat dissipation channel 1044 and smoothly flow through the first heat dissipation channel 1042 before being discharged. This greatly improves heat dissipation efficiency, ensures that key components such as the control box 13 operate stably in a suitable temperature environment, and extends their service life.

[0050] Meanwhile, by setting up heat dissipation channels 104, it is not necessary to set the outer wall of the cabinet 10 far from the cooking cavity 102, nor is it necessary to fill the cooking cavity 102 and the outer wall of the cabinet 10 with thick heat insulation material to reduce the external temperature of the cabinet 10. As a result, the overall volume of the cabinet 10 can be made smaller, making it more compact and lightweight, saving space and making it easier to transport and operate.

[0051] in, Figure 1 The dashed line in the diagram represents the center line. Figure 2 The middle arrow indicates the airflow path.

[0052] In some embodiments, optionally, a first heat dissipation channel 1042 is disposed on the top of the cooking cavity 102, and a second heat dissipation channel 1044 is disposed on the side of the cooking cavity 102.

[0053] In these embodiments, the first heat dissipation channel 1042 can be disposed at the top of the cooking cavity 102, thus prioritizing heat dissipation from the high-temperature area at the top of the cooking cavity 102, effectively preventing heat accumulation at the top and ensuring the stability and safety of the upper structure of the cooking appliance 1. The second heat dissipation channel 1044 is disposed on the side of the cooking cavity 102, which can specifically reduce the temperature on the side of the cooking cavity 102, reducing the impact of high side temperature on surrounding components. At the same time, the cooperation of the top and side heat dissipation channels 104 allows the heat in the cooking cavity 102 to be dissipated more evenly and quickly, improving the overall heat dissipation efficiency, ensuring that the temperature of each part of the cooking appliance 1 remains within a reasonable range during operation, and improving the reliability and service life of the equipment.

[0054] In some embodiments, optionally, the first heat dissipation channel 1042 is arranged in the horizontal direction, and the second heat dissipation channel 1044 is arranged in the vertical direction (e.g., ...). Figure 1 (The direction indicated by A in the middle) setting.

[0055] In these embodiments, the first heat dissipation channel 1042 is arranged horizontally, enabling airflow to flow evenly across key components in the horizontal direction, achieving rapid heat dissipation and ensuring uniform heat distribution at the horizontal level. The second heat dissipation channel 1044 is arranged vertically, effectively utilizing the principle of hot air rising and cold air sinking, promoting natural convection of hot and cold air, allowing heat to be discharged more smoothly upwards, improving the efficiency and effectiveness of heat dissipation. The combined arrangement of these two channels makes full use of space, forming a three-dimensional heat dissipation circulation, maximizing the optimization of the temperature distribution inside the cooking appliance 1, reducing the risk of localized overheating, and ensuring the stability and reliability of the equipment operation.

[0056] In some embodiments, the cooking appliance 1 may optionally include an air outlet 1062 disposed in the housing 10 and communicating with the first heat dissipation channel 1042.

[0057] In these embodiments, an air outlet 1062 connected to the first heat dissipation channel 1042 is provided, which can effectively and promptly discharge the hot air passing through the first heat dissipation channel 1042 into the housing 10, preventing the hot air from lingering in the housing 10, thereby accelerating the heat dissipation speed and maintaining a low-temperature environment inside the housing 10.

[0058] In some embodiments, the air outlet 1062 is optionally located on the side of the housing 10.

[0059] In these embodiments, the air outlet 1062 is located on the side of the housing 10, which prevents the exhausted hot air from blowing directly onto the operator, improving safety and comfort. The hot air exhausted from the side can diffuse more quickly into the surrounding environment, reducing the accumulation of hot air near the housing 10 and thus lowering the ambient temperature around the housing 10. At the same time, the side air outlet 1062 does not affect the front and top operating areas of the housing 10, ensuring the overall integrity and aesthetics of the cooking appliance 1.

[0060] In some embodiments, the housing 10 optionally includes an outer shell 106 and a cooking cavity 108, the cooking cavity 108 having an opening 1082, and the cooking appliance 1 further includes a door assembly 14 disposed at the opening 1082 for opening or closing the opening 1082; when the door assembly 14 closes the opening 1082, an exhaust gap 15 is formed between the door assembly 14 and the outer shell 106, and an air outlet 1062 is disposed at the exhaust gap 15.

[0061] In these embodiments, the housing 10 includes an outer shell 106 and a cooking cavity 108. The outer shell 106 covers the cooking cavity 108, providing protection. The cooking cavity 108 has an opening 1082, allowing food to be placed into or removed through the opening. A door assembly 14 can also be provided to open or close the opening 1082. When the door assembly 14 closes the opening 1082, an exhaust gap 15 is formed between the door assembly 14 and the outer shell 106. An air outlet 1062 is located at the exhaust gap 15, allowing gas from the first heat dissipation channel 1042 to be directed into the exhaust gap 15. It is understandable that by setting the air outlet 1062 at the exhaust gap 15, not only can the hot air of the first heat dissipation channel 1042 be discharged through the exhaust gap 15, but the air outlet 1062 is also not exposed, which improves the overall aesthetics of the cooking appliance 1. In addition, it can also prevent external dust and other impurities from entering the first heat dissipation channel 1042 through the air outlet 1062.

[0062] In some embodiments, the air outlet 1062 is optionally located on the side of the housing 106. The air inlet 12 is located on the bottom of the housing 106.

[0063] In some embodiments, optionally, the exhaust gap 15 is inclined upward from inside the door assembly 14 to outside the door assembly 14 along the height direction of the housing 10.

[0064] In these embodiments, along the height direction of the housing 10, the exhaust gap 15 is inclined upwards from the inside to the outside of the door assembly 14. That is, the exhaust gap 15 is inclined and inclined upwards from the inside to the outside of the door assembly 14. It is understood that when using the cooking appliance 1, users mostly stand directly in front of the cooking appliance 1, that is, on one side of the door assembly 14. Therefore, by inclining the exhaust gap 15 upwards from the inside to the outside of the door assembly 14, the hot air exhausted from the exhaust gap 15 blows obliquely upwards and will not blow directly towards the user, thereby ensuring that the user is not blown by the hot air, ensuring the user's safety and improving the user experience.

[0065] In some embodiments, optionally, the heat dissipation channel 104 is disposed between the housing 106 and the cooking cavity 108, and the cooking appliance 1 further includes: a heat insulation component 16 surrounding the cooking cavity 108, and the heat insulation component 16 and the housing 106 forming the heat dissipation channel 104.

[0066] In these embodiments, to further reduce the temperature of the outer casing 106, a heat insulation component 16 can be provided between the cooking cavity 108 and the outer casing 106. The heat insulation component 16 provides insulation, thereby further reducing the temperature of the outer casing 106. Specifically, the heat insulation component 16 surrounds the cooking cavity 108, and the heat insulation component 16 and the outer casing 106 form a heat dissipation channel 104. This allows the cooling fan 11 to be placed between the heat insulation component 16 and the outer casing 106, thereby reducing the requirements for the cooling fan 11. Heat dissipation can be achieved without the need for a high-temperature resistant cooling fan 11, reducing the cost of the cooling fan 11.

[0067] In some embodiments, the cooking appliance 1 may optionally include a heat dissipation fan 11, which is disposed in the heat dissipation channel 104 and is disposed corresponding to the air inlet 12, for blowing air into the heat dissipation channel 104.

[0068] In these embodiments, in order to further accelerate airflow and improve heat dissipation, a cooling fan 11 can be provided in the heat dissipation channel 104, so that the cooling fan 11 is corresponding to the air inlet 12. This allows the cooling fan 11 to absorb more outside cold air, thereby improving the heat dissipation effect.

[0069] In some embodiments, the air inlet 12 may be positioned directly opposite the cooling fan 11, or the air inlet 12 may be positioned offset from the cooling fan 11.

[0070] In some embodiments, the cooling fan 11 is optionally disposed at one end of the second cooling channel 1044 away from the first cooling channel 1042.

[0071] In these embodiments, the cooling fan 11 can be positioned at the end of the second heat dissipation channel 1044 away from the first heat dissipation channel 1042. This allows for smoother airflow within the heat dissipation channel 104, thereby removing more heat and improving the heat dissipation effect. Simultaneously, because the cooling fan 11 is positioned at the end of the second heat dissipation channel 1044 away from the first heat dissipation channel 1042, airflow will flow from that end of the second heat dissipation channel 1044 towards the first heat dissipation channel 1042. In other words, the airflow can flow through the entire second heat dissipation channel 1044, thus removing more heat from within the second heat dissipation channel 1044.

[0072] In some embodiments, the control box 13 is optionally disposed in the second heat dissipation channel 1044; the control box 13 includes an air passage 132, the air passage 132 extends in the same direction as the second heat dissipation channel 1044, and at least part of the airflow in the second heat dissipation channel 1044 can flow through the air passage 132.

[0073] In these embodiments, by placing the control box 13 in the second heat dissipation channel 1044, at least a portion of the airflow entering from the air inlet 12 can directly act on the air passage 132 of the control box 13, thereby dissipating heat from the electronic components inside the control box 13.

[0074] It is understandable that since the air passage 132 and the second heat dissipation passage 1044 extend in the same direction, the airflow direction is also the same, making it easier for the airflow to enter the air passage 132. This arrangement allows the airflow entering from the outside to first flow through the air passage 132, exit from the air passage 132, and then flow to the second heat dissipation passage 1044, or the airflow can directly flow to the first heat dissipation passage 1042 after exiting the air passage 132. That is, the air outlet of the air passage 132 is connected to the second heat dissipation passage 1044 or the first heat dissipation passage 1042.

[0075] In some embodiments, the cooling fan 11 is optionally located outside the control box 13, and the air outlet of the cooling fan 11 is opposite to the air inlet of the air passage 132.

[0076] In these embodiments, by setting the air outlet of the cooling fan 11 opposite to the air inlet of the air passage 132, most, or even all, of the airflow blown out by the cooling fan 11 can flow through the air passage 132, thereby further improving the heat dissipation effect on the electronic components inside the control box 13.

[0077] In some embodiments, the cooling fan 11 may be fixedly installed outside the control box 13, or it may be directly fixedly installed inside the second heat dissipation channel 1044.

[0078] In some embodiments, the control box 13 may optionally include: a box body 134 disposed in the second heat dissipation channel 1044, and an air passage 132 disposed in the box body 134; a mounting plate 136 disposed in the air passage 132; and a circuit board assembly 138 disposed in the air passage 132 and mounted on the mounting plate 136.

[0079] In these embodiments, the control box 13 includes a housing 134, a mounting plate 136, and a circuit board assembly 138. The housing 134 is disposed within a second heat dissipation channel 1044, and an air passage 132 is disposed on the housing 134. The mounting plate 136 and the circuit board assembly 138 are both disposed within the air passage 132, thus allowing heat dissipation for the circuit board assembly 138 through the air passage 132. Since the circuit board assembly 138 is disposed within the air passage 132 of the housing 134, the housing 134 can protect the circuit board assembly 138 and isolate it from dust and electrostatic interference.

[0080] To facilitate the installation of the housing 134 and ensure its stability, the housing 134 can be mounted on the heat insulation component 16 or on the outer shell 106. Alternatively, the housing 134 can be mounted together with the cooling fan 11. When the housing 134 is mounted on the heat insulation component 16, a certain gap can be left between the housing 134 and the outer shell 106.

[0081] It is understandable that the air passage 132 can be formed by directly opening air inlet and air outlet holes on opposite sides of the box 134, so that airflow can enter the box 134 from the air inlet holes and then be discharged from the air outlet holes, thus achieving heat dissipation of the circuit board assembly 138 inside the box 134.

[0082] Meanwhile, by mounting the circuit board assembly 138 on the mounting plate 136, the temperature of the circuit board assembly 138 is further reduced.

[0083] In some embodiments, the cooking appliance 1 may optionally include at least one of a pizza oven, an oven, a grill, a steamer, and a microwave oven.

[0084] In some embodiments, the cooling fan 11 may optionally include at least one of a cross-flow fan, an axial flow fan, and a mixed flow fan.

[0085] According to an embodiment of the first aspect of this utility model, a cooking appliance is provided, which will be described as a pizza oven. The pizza oven includes a heat dissipation duct. Under the action of a cross-flow fan, cold air enters from the bottom plate, passes sequentially through the cross-flow fan, the power board (circuit board assembly), the heat insulation board assembly (heat insulation component), the channel between the outer cover (shell), and the front panel air outlet, and finally exits from the gap between the front panel and the oven door. The heat dissipation duct 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 currently existing in pizza ovens. The heat dissipation duct has high heat dissipation efficiency and effectively solves the problems of surface temperature rise and power board temperature rise in pizza ovens.

[0086] The heat dissipation duct of this application has high heat dissipation efficiency, which can effectively reduce the distance between the cooking cavity and the outer shell, thereby solving the problems of large size and heavy weight of current pizza ovens, as well as effectively solving the problem of temperature rise of the power board of pizza ovens.

[0087] The beneficial technical effects of this application are as follows:

[0088] 1. By reducing the ambient temperature of the pizza oven's outer shell and power board components, the main technical challenges of pizza ovens have been solved.

[0089] 2. The heat dissipation duct has high heat dissipation efficiency, which can effectively reduce the distance between the cavity and the outer shell, thereby solving the problems of large size and heavy weight of current pizza ovens.
