Description

Technical Field

[0001] This application relates to the field of cooking appliance technology, and more particularly to a cooking utensil. Background Technology

[0002] Microwaves offer the advantage of fast cooking, and more and more cooking appliances are equipped with microwave functions, such as many ovens, where microwave functionality is often an optional feature. This means that on the same product platform, some products have microwave functionality, while others only have grilling or steaming functions.

[0003] In related technologies, cooking appliances that offer microwave functionality as an optional feature have a large heat dissipation system designed to ensure overall heat dissipation when the microwave function is enabled. When the microwave function is not enabled, the heat dissipation capacity of the cooking appliance is redundant, resulting in waste. Utility Model Content

[0004] In view of this, the embodiments of this application aim to provide a cooking appliance that helps to improve the problem of wasted heat dissipation capacity of the cooking appliance, and at the same time, it also helps to facilitate the assembly of the overall structure of the cooking appliance when it is configured with different functions.

[0005] To solve the above problems, the technical solution of this application embodiment is implemented as follows:

[0006] This application provides a cooking appliance, including:

[0007] The housing assembly has a cooking cavity and a mounting cavity arranged along the height direction of the cooking appliance. A microwave feed area is provided on the cavity wall of the mounting cavity near the cooking cavity. The microwave feed area and the cavity walls of the mounting cavity on both sides along the first direction are spaced apart.

[0008] A heating element is disposed in the mounting cavity and spaced apart from the microwave feed area along the first direction;

[0009] A first air duct assembly is disposed in the mounting cavity. The first air duct assembly is provided with a first air duct. The inlet of the first air duct is connected to the mounting cavity. The first air duct avoids the microwave feed area and does not extend beyond the side of the microwave feed area away from the heating element.

[0010] The first fan is located in the first air duct.

[0011] In some embodiments, the cooking appliance further includes a microwave generating component, a second air duct component, and a second fan. The microwave generating component feeds microwaves into the cooking cavity through the microwave feed area. The microwave generating component includes a heating element. The second air duct component is provided with a second air duct, which is located on the side of the microwave feed area away from the heating element. The heating element and the second fan are both located in the second air duct.

[0012] In some embodiments, a ventilation hole is provided through the cavity wall on the side away from the heating element along the first direction of the mounting cavity, and the outlet of the second air duct faces the ventilation hole and is in communication with the gas through the ventilation hole.

[0013] In some embodiments, the second air duct assembly is further provided with a third air duct, which extends along the first direction and is located on one side of the microwave feed area along the second direction. The third air duct is connected to the first air duct and the second air duct respectively; wherein the first direction, the second direction and the height direction of the cooking appliance intersect each other.

[0014] In some embodiments, the second fan is an axial flow fan or a centrifugal fan.

[0015] In some embodiments, the first air duct assembly has a connecting port on the side opposite to the cooking cavity, and the third air duct is connected to the first air duct through the connecting port.

[0016] In some embodiments, the microwave generating assembly further includes a transmitting antenna located on the side of the heating element near the heating part, and the angle between the extending direction and the first direction is an acute angle.

[0017] In some embodiments, the angle between the extending direction of the transmitting antenna and the first direction is less than or equal to 30°.

[0018] In some embodiments, the first fan and the second fan are located on the same side of the microwave feed area along the second direction, and the first direction, the second direction, and the height direction of the cooking appliance intersect each other.

[0019] In some embodiments, the heating element, the first fan, and the second fan are arranged sequentially along the first direction.

[0020] In some embodiments, the first air duct assembly includes a first plate and a second plate, the first plate having a recessed area, the second plate being disposed on the side of the first plate away from the cooking cavity and defining the first air duct with the recessed area, the recessed area avoiding the microwave feed area.

[0021] In some embodiments, along the first direction, the first plate and the second plate define an outlet for the first air duct on the side of both facing away from the microwave feed region, and the heating element is located on the side of the second plate facing away from the first plate.

[0022] In some embodiments, the outlet of the first air duct extends along a second direction and extends to opposite sides of the recessed area along the second direction, wherein the first direction, the second direction, and the height direction of the cooking appliance intersect each other.

[0023] In some embodiments, the inlet of the first air duct is located on the side of the first air duct assembly opposite to the cooking cavity, and the first fan is a centrifugal fan.

[0024] In the cooking appliance of this embodiment, the inlet of the first air duct connects to the mounting cavity, and the heating element is disposed within the mounting cavity. That is, the heat from the heating element is dissipated into the cooking cavity, and the first air duct exhausts the heat dissipated into the mounting cavity, thereby achieving heat dissipation for the heating element. Therefore, whether the cooking appliance is equipped with a microwave function or not, the first air duct assembly and the first fan can fully utilize their heat dissipation capabilities. This helps to improve the problem of wasted heat dissipation capacity when the cooking appliance is not equipped with a microwave function. The first air duct avoids the microwave feed area and does not extend beyond the side of the microwave feed area away from the heating element. Thus, the first air duct does not affect the assembly and disassembly of the waveguide. Simultaneously, the mounting cavity has relatively ample space on the side of the microwave feed area away from the heating element. Therefore, there is sufficient space in this area to arrange components for heat dissipating the microwave generating assembly. The first air duct and the first fan also do not affect the assembly and disassembly of components related to the microwave function, thus facilitating the assembly convenience of products with different functions.

[0042] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0043] This application provides a cooking utensil; please refer to [link / reference]. Figure 1 and Figure 2 The cooking appliance includes a housing assembly 10, a heating element 20, a first air duct assembly 30, and a first fan 40.

[0044] It should be noted that there are no restrictions on the specific type of cooking appliance. For example, cooking appliances can be microwave ovens, ovens, steamers, air fryers, or microwave-steam-oven combos, etc.

[0045] The housing assembly 10 has a cooking cavity 10a and a mounting cavity 10b arranged along the height direction of the cooking appliance.

[0046] Here, the height orientation of cooking utensils needs to be understood based on their position and orientation when in normal use. Specifically, the height orientation of cooking utensils is... Figure 1 , Figure 3 , Figure 5 , Figures 7 to 9 The direction indicated by H in the middle.

[0047] The cooking cavity 10a is used to hold food ingredients, and cooking utensils are used to cook the food ingredients placed in the cooking cavity 10a.

[0048] The mounting cavity 10b is used to install some components of the cooking appliance, including but not limited to the heating element 20, the first air duct assembly 30, the first fan 40, etc.

[0049] In some embodiments, such as Figure 1 As shown, the mounting cavity 10b can be located above the cooking cavity 10a. Of course, in other embodiments, the mounting cavity 10b can also be located below the cooking cavity 10a.

[0050] The specific structure of the housing assembly 10 is not limited. For example, please refer to [link to relevant documentation]. Figure 1 The housing assembly 10 includes a front cavity plate 11, a rear cavity plate 12, a left cavity plate 13, and a right cavity plate 14.

[0051] Cooking appliances generally also include a door 100, which is located on the front panel 11 of the cavity. The front panel 11 of the cavity has a food loading and unloading opening that communicates with the cooking cavity 10a. The door 100 is used to open or close the food loading and unloading opening.

[0052] It is understood that, among the various plates of the housing assembly 10, the plate on the side opposite to the front plate 11 of the cavity is the rear plate 12 of the cavity. The side where the front plate 11 of the cavity is located is the front side, and the side where the rear plate 12 of the cavity is located is the rear side. Correspondingly, the plate on the left side is the left plate 13 of the cavity, and the plate on the right side is the right plate 14 of the cavity.

[0053] A microwave feed area 10c is provided on the cavity wall of the mounting cavity 10b near the cooking cavity 10a. The microwave feed area 10c and the cavity walls of the mounting cavity 10b on both sides along the first direction are spaced apart.

[0054] Here, the first direction can be the front-to-back direction of the cooking utensil. Specifically, the first direction is, for example, the back-to-back direction of the cooking utensil. Figure 1 , Figure 3 , Figure 5 , Figure 8 and Figure 9 The direction shown in L1. That is to say, the microwave feed area 10c can be spaced apart from both the front plate 11 and the rear plate 12 of the cavity.

[0055] It should be noted that when the mounting cavity 10b is located above the cooking cavity 10a, a microwave feed area 10c is provided on the bottom wall of the mounting cavity 10b; when the mounting cavity 10b is located below the cooking cavity 10a, a microwave feed area 10c is provided on the top wall of the mounting cavity 10b. Specifically, in the embodiments of this application, the example is always described with the mounting cavity 10b located above the cooking cavity 10a.

[0056] The microwave feed region 10c refers to the area on the cavity wall of the mounting cavity 10b used to mount part of the microwave generating assembly 50. For example, please refer to... Figure 1 , Figure 3 and Figure 4 The bottom wall of the mounting cavity 10b has a protruding boss. When the cooking appliance is equipped with a microwave function, the cooking appliance also includes a microwave generating component 50. The microwave generating component 50 includes a waveguide 52. A part of the structure of the waveguide 52 is covered on the boss. The area on the boss covered by the waveguide 52 is the microwave feed area 10c.

[0057] In some embodiments, the central axis of the microwave feed region 10c is approximately overlapped with the central axis of the cooking cavity 10a. This results in a more uniform distribution of microwaves fed into the cooking cavity 10a, which is beneficial for the cooking appliance to cook food more evenly.

[0058] The heating element 20 is disposed in the mounting cavity 10b and spaced apart from the microwave feed area 10c along the first direction.

[0059] The specific type of heating element 20 is not limited. For example, please refer to... Figure 1 The cooking appliance also includes an operation panel 110, which is located on the front panel 11 of the cavity and is spaced apart from the door 100 along the height direction of the cooking appliance. The operation panel 110 includes a display control panel 22. The cooking appliance also includes a power board 21, and both the power board 21 and the wired control panel are heating elements 20 of the cooking appliance.

[0060] The first air duct assembly 30 is located in the mounting cavity 10b. The first air duct assembly 30 is provided with a first air duct 30a. The inlet of the first air duct 30a is connected to the mounting cavity 10b. The first air duct 30a avoids the microwave feed area 10c and does not extend beyond the side of the microwave feed area 10c away from the heating element 20. The first fan 40 is located in the first air duct 30a.

[0061] The inlet of the first air duct 30a is also the first air inlet 32a. The heat emitted by the heating element 20 dissipates into the mounting cavity 10b. Under the action of the first fan 40, this heat is carried by the airflow through the first air inlet 32a into the first air duct 30a, and then exhausted outside the cooking appliance. In other words, the first air duct 30a and the first fan 40 can be used to dissipate heat from the heating element 20, thus improving the heat dissipation effect of the heating element 20, which in turn helps the heating element 20 to work more stably, thereby improving the reliability of the cooking appliance.

[0062] The first air duct 30a avoids the microwave feed area 10c. Specifically, in some embodiments, when projected along the height direction of the cooking appliance, the orthographic projection of the first air duct 30a does not overlap with the orthographic projection of the microwave feed area 10c, so that the first air duct 30a does not affect the assembly and disassembly of the waveguide 52.

[0063] The first air duct 30a not exceeding the side of the microwave feed area 10c away from the heating element 20 means that, along the first direction, the side of the first air duct 30a away from the heating element 20 does not exceed the side of the microwave feed area 10c away from the heating element 20. That is, along the first direction, the distance between the side of the microwave feed area 10c away from the heating element 20 and the heating element 20 is greater than the distance between the side of the first air duct 30a away from the heating element 20 and the heating element 20.

[0064] In this way, the space of the mounting cavity 10b on the side of the microwave feed area 10c away from the heating element 20 will not be occupied by the first air duct 30a, and the mounting cavity 10b has relatively ample space on the side of the microwave feed area 10c away from the heating element 20. The mounting cavity 10b has sufficient space in this area to arrange components for heat dissipation of the microwave generating assembly 50. Since the components for heat dissipation of the heating element 20 (first air duct 30a, first fan 40) are not arranged in this area, the disassembly and assembly of components related to microwave function will not be affected, thus facilitating the assembly convenience of products with different functions.

[0065] Cooking appliances rely on high temperatures to cook food. During operation, the electrical components of these appliances are susceptible to thermal shock and malfunction. Furthermore, for cooking appliances equipped with microwave functions, their electrical components, such as the magnetron 51, inverter, and power board 21, generate a significant amount of heat and require timely heat dissipation to ensure normal operation.

[0066] In related technologies, cooking appliances that offer microwave functionality as an optional feature typically have the microwave feed located in the center of the top or bottom of the cooking cavity, with the magnetron's transmitting antenna extending parallel to the front panel of the cavity. These appliances generally employ a single cross-flow fan cooling system, specifically dividing the cross-flow cooling duct into multiple sub-ducts. One sub-duct cools the magnetron and inverter components of the microwave generator, while another cools the power board, display control board, and other heat-generating components. Cooking appliances using this cooling solution have a large cooling system and a relatively high fan assembly, thus affecting the volume of the cooking cavity. Furthermore, when the appliance does not have microwave functionality, the cooling capacity becomes redundant, resulting in waste.

[0067] In the cooking appliance of this application embodiment, the inlet of the first air duct 30a is connected to the mounting cavity 10b, and the heating element 20 is disposed in the mounting cavity 10b. That is to say, the heat of the heating element 20 is dissipated into the cooking cavity 10a, and the first air duct 30a is used to exhaust the heat dissipated into the mounting cavity 10b, thereby achieving heat dissipation of the heating element 20. Therefore, whether the cooking appliance is equipped with a microwave function or not, the first air duct assembly 30 and the first fan 40 can fully exert their heat dissipation capacity. This helps to improve the problem of wasted heat dissipation capacity caused by the cooking appliance not being equipped with a microwave function. The first air duct 30a avoids the microwave feed area 10c and does not extend beyond the side of the microwave feed area 10c away from the heating element 20. In this way, the first air duct 30a will not affect the disassembly and assembly of the waveguide 52. At the same time, the mounting cavity 10b has relatively ample space on the side of the microwave feed area 10c away from the heating element 20. Therefore, there is enough space in this area to arrange the components used to dissipate heat from the microwave generating assembly 50. The first air duct 30a and the first fan 40 will not affect the disassembly and assembly of components related to microwave functions, thus facilitating the assembly convenience of products with different functions.

[0068] The specific type of the first fan 40 is not limited.

[0069] In some embodiments, please refer to Figure 1 and Figure 2 The inlet of the first air duct 30a is located on the side of the first air duct assembly 30 away from the cooking cavity 10a, and the first fan 40 is a centrifugal fan.

[0070] The first fan 40 is located at the inlet of the first air duct 30a. The axial direction of the centrifugal fan is parallel to the orientation of the inlet of the first air duct 30a; therefore, the axial direction of the centrifugal fan is also parallel to the height direction of the cooking appliance.

[0071] The first fan 40 is a centrifugal fan, and the axial direction of the centrifugal fan is set parallel to the height direction of the cooking appliance. The centrifugal fan has a relatively small axial dimension. Compared with the heat dissipation schemes using cross-flow fans, DC fans, etc. in related technologies, in this embodiment, the space occupied by the first fan 40 in the height direction of the cooking appliance is smaller. Therefore, under the premise that the height dimension of the cooking appliance remains unchanged, it is beneficial to increase the volume of the cooking cavity 10a. Moreover, while ensuring the heat dissipation effect, it is also beneficial to reduce costs and simplify the structure of the heat dissipation system.

[0072] In some embodiments, please refer to Figures 3 to 6 The cooking appliance also includes a microwave generating component 50, a second air duct component 60, and a second fan 70. The microwave generating component 50 feeds microwaves into the cooking cavity 10a through the microwave feed area 10c. The microwave generating component 50 includes a heating element 511. The second air duct component 60 is provided with a second air duct 61a. The second air duct 61a is located on the side of the microwave feed area 10c away from the heating element 20. The heating element 511 and the second fan 70 are both located in the second air duct 61a.

[0073] Specifically, the second air duct assembly 60 includes a first air duct 61, the first air duct 61 is provided with a second air duct 61a, and the first air duct 61 is located on the side of the microwave feed area 10c away from the heating element 20.

[0074] Here, the microwave generating assembly 50 includes a magnetron 51 and a waveguide 52, and the heating element 511 is a part of the structure on the magnetron 51.

[0075] In this embodiment, the heating element 511 of the microwave generating assembly 50 dissipates heat through the second air duct assembly 60 and the second fan 70. That is, the heating element 20 and the heating element 511 each use a separate heat dissipation system, which helps to ensure the overall heat dissipation effect of the cooking appliance. Moreover, the second air duct 61a is located on the side of the microwave feed area 10c away from the heating element 20. That is, the first air duct 30a and the second air duct 61a do not overlap in the height scheme of the cooking appliance. Therefore, the first air duct 30a will not affect the disassembly and assembly of the second air duct 61a. The microwave generating assembly 50, the second air duct assembly 60, and the second fan 70 can all be easily disassembled and assembled. Whether the cooking appliance is equipped with microwave function or not, it will not affect the layout of the first fan 40 and the first air duct assembly 30. This helps to improve the compatibility of the cooking appliance.

[0076] It should be noted that the specific type of the second fan 70 is not limited. For example, please refer to [link to relevant documentation]. Figures 3 to 6 The second fan 70 is an axial flow fan or a centrifugal fan.

[0077] In some embodiments, please refer to Figure 7and Figure 9 The microwave generating assembly 50 also includes a transmitting antenna 512, which is located on the side of the heating part 511 near the heating element 20 and the angle between its extension direction and the first direction is an acute angle.

[0078] Here, the transmitting antenna 512 is a part of the structure on the magnetron 51.

[0079] It is understandable that a waveguide 52 needs to be installed in the space near the transmitting antenna 512 of the heating part 511. Therefore, the extension direction of the second air duct 61a is roughly perpendicular to the extension direction of the transmitting antenna 512, so as to facilitate the layout of the first air duct 61.

[0080] In this embodiment, by setting the extension direction of the transmitting antenna 512 to be at an acute angle to the first direction, the first duct 61 can be laid out as much as possible in a direction perpendicular to the first direction. The space occupied by the first duct 61 in the first direction is smaller, which makes it easier to set the first duct 61 on the side of the microwave feed area 10c away from the heating element 20.

[0081] In some embodiments, please refer to Figure 7 and Figure 9 The angle between the extension direction of the transmitting antenna 512 and the first direction is less than or equal to 30°. For example, it can be 0°, 2°, 4°, 6°, 8°, 10°, 12°, 14°, 16°, 18°, 20°, 22°, 24°, 26°, 28°, 30°, etc.

[0082] It is understandable that when the included angle is 0°, it means that the extension direction of the transmitting antenna 512 is parallel to the first direction. This makes it easier to set the first duct 61 to extend in a direction perpendicular to the first direction, which helps to further reduce the space occupied by the second duct 62 in the first direction and makes it easier to set the first duct 61 on the side of the microwave feed area 10c away from the heating element 20.

[0083] In some embodiments, please refer to Figure 3 and Figure 5 The heating element 20, the first fan 40, and the second fan 70 are arranged sequentially along the first direction. Specifically, the heating element 20, the inlet of the first air duct 30a, and the inlet of the second air duct 61a are arranged sequentially along the first direction.

[0084] The inlet of the first air duct 30a is the first air duct inlet 32a, and the inlet of the second air duct 61a is the second air duct inlet 61b.

[0085] In this way, the air inlet 32a of the first air duct is closer to the heating element 20, allowing the heat emitted by the heating element 20 to enter the first air duct 30a more quickly with the airflow, and then be discharged to the outside of the cooking appliance through the first air duct 30a. Meanwhile, the air inlet 61b of the second air duct is relatively far from the heating element 20, making it more difficult for the heat emitted by the heating element 20 to enter the second air duct 61a. This helps control the temperature of the airflow entering the second air duct 61a, thereby improving the heat dissipation effect on the heating part 511 of the magnetron 51.

[0086] In some embodiments, please refer to Figures 1 to 4 , Figure 8 , Figure 9 The first air duct assembly 30 includes a first plate 31 and a second plate 32. The first plate 31 is provided with a recessed area 31a. The second plate 32 is located on the side of the first plate 31 away from the cooking cavity 10a and is defined by the recessed area 31a to form the first air duct 30a. The recessed area 31a avoids the microwave feed area 10c.

[0087] It should be noted that the structure of the first plate 31 can be the same or different depending on whether the cooking appliance has a microwave function or not. Using the same structure for the first plate 31 helps to improve its versatility.

[0088] For example, please refer to Figure 1 and Figure 2 When the cooking appliance is not equipped with a microwave function, the first plate 31 only needs to meet the dimensional requirements for setting the first air duct 30a. For example, please refer to... Figure 3 and Figure 4 When the cooking appliance is equipped with a microwave function, the coverage area of ​​the first plate 31 is increased, and its coverage area is close to the area of ​​the bottom wall of the mounting cavity 10b. In this way, when the microwave function is not configured, it is beneficial to reduce the cost of the cooking appliance. When the microwave function is configured, increasing the coverage area of ​​the first plate 31 helps to improve the structural strength of the bottom wall of the mounting cavity 10b, thereby improving the reliability of the cooking appliance.

[0089] In this embodiment, the first air duct 30a is formed by defining the first plate 31 and the second plate 32, which helps to simplify the structure of each sub-component of the first air duct assembly 30 and facilitates the production and molding of the first air duct assembly 30.

[0090] In some embodiments, please refer to Figure 1 , Figures 7 to 9 Along the first direction, the first plate 31 and the second plate 32 define the outlet of the first air duct 30a on the side of both facing away from the microwave feed region 10c.

[0091] In this way, the air in the first air duct 30a flows out through the front side of the cooking appliance, specifically, as shown in the example... Figures 7 to 9 As shown, a gap is formed between the operation panel 110 and the door 100, and the outlet of the first air duct 30a is connected to this gap.

[0092] The cooking appliance can be, for example, a built-in cooking appliance. Therefore, the air in the first air duct 30a flows out through the front side of the cooking appliance, and the flow is smoother, which helps to improve the heat dissipation effect of the cooking appliance.

[0093] The heating element 20 is located on the side of the second plate 32 opposite to the first plate 31. Specifically, the cooking appliance also includes a mounting bracket 80, which is located on the side of the second plate 32 opposite to the first plate 31, and the power board 21 is mounted on the mounting bracket 80. In this way, the air flowing out of the outlet of the first air duct 30a will not impact the heating element 20 again, thereby improving the heat dissipation effect on the heating element 20.

[0094] In some embodiments, please refer to Figure 1 and Figure 2 The outlet of the first air duct 30a extends along the second direction and extends to the opposite sides of the recessed area 31a along the second direction, wherein the first direction, the second direction and the height direction of the cooking utensil intersect each other.

[0095] Specifically, the first direction, the second direction, and the height direction of the cooking utensil can be orthogonal to each other.

[0096] The second direction could be, for example, the left-right direction of the cooking utensil. For instance, the second direction could be... Figure 1 , Figure 3 , Figure 5 and Figure 7 The direction indicated by L2 in the middle.

[0097] In this embodiment, the size of the outlet of the first air duct 30a can be extended as much as possible along the extension direction of the gap between the operation panel 110 and the door 100. In this way, the air in the first air duct 30a can be discharged as much as possible through the gap between the operation panel 110 and the door 100, which is beneficial to further improve the heat dissipation effect on the heat-generating element 20.

[0098] In some embodiments, please refer to Figure 3 and Figure 4 A ventilation hole 12a is provided through the cavity wall of the mounting cavity 10b on the side away from the heating element 20 along the first direction. The outlet of the second air duct 61a faces the ventilation hole 12a and is connected to the gas in the ventilation hole 12a.

[0099] The outlet of the second air duct 61a is the air outlet 61c of the second air duct.

[0100] In this embodiment, the air in the second air duct 61a can be discharged through the ventilation hole 12a, which makes ventilation more convenient. At the same time, the second air duct assembly 60 may only include the first air duct 61, which helps to simplify the structure of the second air duct assembly 60, and at the same time, the second air duct assembly 60 occupies less space in the mounting cavity 10b.

[0101] In some embodiments, please refer to Figure 5 and Figure 6 The second air duct assembly 60 is also provided with a third air duct 62a, which extends along the first direction and is located on one side of the microwave feed area 10c along the second direction. The third air duct 62a is connected to the first air duct 30a and the second air duct 61a respectively.

[0102] Specifically, the second air duct assembly 60 also includes a second air duct 62, which is provided with a third air duct 62a.

[0103] Here, the cooking appliance also includes a water tank assembly 90, which extends along a first direction, and a second air duct 62 is disposed in the area between the water tank assembly 90 and the microwave feed area 10c.

[0104] In this embodiment, the air in the second air duct assembly 60 can be discharged through the outlet of the first air duct 30a. In this way, the first air duct assembly 30 and the second air duct assembly 60 share a common exhaust port, and the air is discharged more smoothly from the outlet of the first air duct 30a, which helps to improve the heat dissipation effect on the heat-generating part 511 of the microwave generating assembly 50.

[0105] Furthermore, since the air in the third air duct 62a flows from back to front, after extending the two sides of the outlet of the first air duct 30a to the opposite sides of the recessed area 31a along the second direction, the air in the third air duct 62a can be directly discharged through the outlet of the first air duct 30a after entering the first air duct 30a. This helps to reduce the turbulence problem caused by the mutual impact of airflow in the first air duct 30a, thereby improving the exhaust efficiency.

[0106] In some embodiments, please refer to Figure 5 and Figure 6 The first air duct assembly 30 has a connecting port 32b on the side opposite to the cooking cavity 10a, and the third air duct 62a is connected to the first air duct 30a through the connecting port 32b.

[0107] Specifically, a connecting port 32b is provided through the second plate 32.

[0108] Thus, the second air duct 62 will be positioned on the side of the first air duct assembly 30 facing away from the cooking cavity 10a. Specifically, when the mounting cavity 10b is located above the cooking cavity 10a, the connection point between the second air duct 62 and the first air duct assembly 30 is located above the first air duct assembly 30; when the mounting cavity 10b is located below the cooking cavity 10a, the connection point between the second air duct 62 and the first air duct assembly 30 is located below the first air duct assembly 30.

[0109] Thus, the first air duct assembly 30 does not need to be moved during the disassembly and assembly of the second air duct 62. Therefore, whether or not the cooking appliance is equipped with a microwave function will not affect the layout of the first air duct assembly 30, thereby improving the compatibility of the cooking appliance.

[0110] In some embodiments, please refer to Figure 3 and Figure 5 The first fan 40 and the second fan 70 are located on the same side of the microwave feed area 10c along the second direction.

[0111] Specifically, a second duct 62 is arranged along one side of the microwave feed area 10c, and a first fan 40 and a second fan 70 are arranged on the other side.

[0112] In this way, there is enough space to install the second air duct 62 on the other side of the microwave feed area 10c along the second direction, resulting in better overall compatibility and a more compact layout for the cooking appliances.

[0113] Furthermore, it facilitates the introduction of air from the second air duct assembly 60 into the first air duct 30a at a position further away from the first air duct inlet 32a, thereby reducing the impact on the air intake of the first air duct inlet 32a, which in turn helps to ensure the heat dissipation effect of the heat-generating element 20.
