The air scoop 100 proposed by the utility model is suitable for being covered with the frequency converter 1 and / or the magnetron 2, so that the airflow in the air scoop 100 can dissipate heat for the frequency converter 1 and / or the magnetron 2.

[0036] Reference Figure 2 , Figure 3 and Figure 4 According to the embodiment of the utility model, the air guide cover 100 comprises: a body 3, a heat dissipation cavity 31 is arranged in the body 3, the body 3 is provided with an air inlet 32 ​​and an air outlet 33 connected with the heat dissipation cavity 31, and the heat dissipation cavity 31 comprises a first heat dissipation area 34 for installing the magnetron 2. When the air guide cover 100 is assembled in the cooking device 300, the magnetron 2 is located in the first heat dissipation area 34. When the cooking device 300 is working, the fan 8 of the cooking device 300 drives air to enter the heat dissipation cavity 31 through the air inlet 32, and the magnetron 2 is cooled when passing through the first heat dissipation area 34, and then discharged through the air outlet 33. The magnetron 2 is cooled by the airflow flowing in the heat dissipation cavity 31, so as to ensure the normal use of the magnetron 2.

[0037] Reference Figure 2 , Figure 4 and Figure 5 The air guide cover 100 also includes a first mounting component 35, which is arranged on the main body 3 for fixing the inverter 1, that is, the inverter 1 can be installed on the air guide cover 100 through the first mounting component 35, and then assembled to the cooking device 300 through the air guide cover 100. The cooking device 300 does not need to be provided with an inverter mounting bracket, which reduces the number of parts of the cooking device 300, reduces the production cost and installation time, and reduces the cost of the cooking device 300.

[0038] According to the air guide cover 100 of the embodiment of the utility model, a first heat dissipation cavity 31 is provided, which can dissipate heat for the magnetron 2 to ensure the normal use of the magnetron 2; the air guide cover 100 is also provided with a first mounting component 35, so that the air guide cover 100 can fix the inverter 1. The cooking device 300 equipped with the air guide cover 100 proposed by the utility model does not need to be provided with an inverter mounting bracket, which reduces the number of parts of the cooking device 300, reduces the production cost and installation time, and reduces the cost of the cooking device 300.

[0039] Reference Figure 2 , Figure 4 and Figure 5 In some embodiments, the first mounting component 35 is located in the heat dissipation cavity 31 .

[0040] Through the above technical solution, that is, when the inverter 1 is fixed to the body 3 through the first mounting component 35, the inverter 1 is located in the heat dissipation cavity 31. When the cooking device 300 is working, the inverter 1 can also be cooled by the airflow in the heat dissipation cavity 31, thereby ensuring the normal operation of the inverter 1 and improving the safety of the cooking device 300. The air guide cover 100 can simultaneously cool the inverter 1 and the magnetron 2, thereby improving the reliability of the air guide cover 100.

[0041] Reference Figure 2 , Figure 4 and Figure 5 In some further embodiments, in the direction from the air inlet 32 ​​toward the air outlet 33 , the first mounting component 35 is located on a side of the first heat dissipation region 34 facing the air inlet 32 ​​.

[0042] Through the above technical solution, when the fan 8 of the cooking device 300 is working, the air enters the heat dissipation cavity 31 through the air inlet 32, passes through the first installation component 35, then passes through the first heat dissipation area 34, and finally is discharged through the air outlet 33. Because the heat generated by the inverter 1 is lower than the heat generated by the magnetron 2, through the design of the above technical solution, the airflow in the heat dissipation air first dissipates the heat of the inverter 1 and then dissipates the heat of the magnetron 2, which makes full use of the coldness of the air and improves the heat dissipation efficiency of the inverter 1 and the magnetron 2.

[0043] Reference Figure 2 , Figure 4 and Figure 5 In some embodiments, the first mounting component 35 includes a first fixing portion 351 and a first stop portion 352.

[0044] Through the above technical solution, when the inverter 1 is installed in the air guide cover 100, the inverter 1 is first abutted against the first fixing portion 351 and the first abutting portion 352, and then the fixing connector passes through the inverter 1 and cooperates with the first fixing hole 3511, thereby fixing the inverter 1 to the body 3. The fixing connector can be a screw or a bolt, which has high connection stability and low cost.

[0045] In the above technical solution, the installation method of the inverter 1 is simple and easy to operate, and the inverter 1 is connected to the main body 3 through a fixed connection piece, and the connection stability is high, which ensures the stability of the use of the cooking device 300.

[0046] In some embodiments, the first mounting portion also includes an insertion portion 353, which is arranged on the inner wall of the heat dissipation cavity 31. When the inverter 1 is installed on the main body 3, the insertion portion 353 is inserted between the high-voltage components of the inverter 1 to reduce the risk of high-voltage breakdown between the high-voltage components.

[0047] Reference Figure 2 , Figure 4 and Figure 5 In some specific embodiments, in the direction from the air inlet 32 ​​to the air outlet 33, a side wall of the air guide cover 100 is opened to form an open opening 36, and the open side of the air guide cover 100 is suitable for fitting with the bottom plate assembly 4 of the cooking device 300, and the open opening 36 is closed by the bottom plate assembly 4.

[0048] In the above technical solution, one side wall of the air guide cover 100 is opened, which reduces the material used for the air guide cover 100 , is beneficial to the lightweight of the air guide cover 100 , and is beneficial to reducing the cost of the air guide cover 100 .

[0049] Reference Figure 2 , Figure 4 and Figure 5 In some further embodiments, the first mounting component 35 is disposed on the inner wall of the heat dissipation cavity 31 directly opposite to the open opening 36 .

[0050] Through the above technical solution, when installing the inverter 1 on the main body 3, first place the side of the main body 3 with the open mouth 36 facing upward, then place the inverter 1 in the heat dissipation cavity 31 through the open mouth 36, and place the inverter 1 on the first fixing portion 351 and the first stop portion 352, and finally fix the inverter 1 on the main body 3 by the cooperation of the fixing connecting piece and the first fixing hole 3511.

[0051] In the above technical solution, the first installation component 35 is arranged on the inner wall of the heat dissipation cavity 31 opposite to the open opening 36 , which increases the operating space for workers to install the inverter 1 and improves the assembly efficiency of the cooking device 300 .

[0052] Reference Figure 2 , Figure 4 and Figure 5 In some specific embodiments, a first fitting portion 37 is provided on one side of the body 3 provided with the open opening 36. The first fitting portion 37 is provided around the open opening 36, and the first fitting portion 37 is provided with a plurality of first mounting holes 371. The first fitting portion 37 is adapted to fit with the bottom plate assembly 4 of the cooking device 300, and the body 3 is adapted to fit with the bottom plate assembly 4 after the fixing connecting member passes through the first mounting holes 371 to fix the air guide cover 100 to the bottom plate assembly 4. The fixing connecting member may be a screw or a bolt, which has high connection stability and low cost.

[0053] In the above technical solution, the air guide cover 100 is installed in a simple manner and has high connection stability.

[0054] Reference Figure 2 , Figure 3 and Figure 4 In some specific embodiments, a avoidance opening 341 communicating with the heat dissipation cavity 31 is provided at a position corresponding to the first heat dissipation area 34 of the main body 3. When the air guide cover 100 is assembled on the cooking device 300, a portion of the magnetron 2 passes through the avoidance opening 341 to be located outside the heat dissipation cavity 31, so as to facilitate the connection between the magnetron 2 and other components of the cooking device 300.

[0055] Reference Figure 2 , Figure 3 and Figure 4 In some embodiments, the body 3 is provided with a through hole 38 connected to the heat dissipation cavity 31, and the through hole 38 is suitable for passing the condenser 6. The condenser 6 is provided with an exhaust hole 61 located in the heat dissipation cavity 31 and connected to the internal cavity of the cooking cavity 7.

[0056] When the cooking device 300 is working, the excess gas in the cooking cavity 7 can be discharged to the condenser tube 6, and then discharged to the heat dissipation cavity 31 through the exhaust hole 61 on the condenser tube 6, and then discharged through the air outlet 33. Through the above technical solution, the exhaust efficiency of the excess gas in the cooking cavity 7 is improved. When the excess gas in the cooking cavity 7 is mainly steam, part of the steam can be condensed in the condenser tube 6, and then flow back into the cooking cavity 7 for reuse. Because at least part of the condenser tube 6 is inserted into the heat dissipation cavity 31, the condensation efficiency of the condenser tube 6 is improved by the air flowing in the heat dissipation cavity 31.

[0057] Furthermore, through the above technical solution, the air guide cover 100 can also be used to fix the condenser 6, and the cooking device 300 does not need to be provided with a condenser 6 fixing bracket, thereby reducing the number of parts of the cooking device 300, reducing the production cost and installation time, and reducing the cost of the cooking device 300.

[0058] Reference Figure 2 , Figure 3 and Figure 4 In some further embodiments, in the direction from the air inlet 32 ​​toward the air outlet 33 , the through hole 38 is located on a side of the first heat dissipation region 34 facing the air outlet 33 .

[0059] The above technical solution prevents the airflow discharged from the condenser 6 from flowing to the magnetron 2 and the inverter 1, prevents the magnetron 2 / inverter 1 from being short-circuited due to the influence of condensed water, and improves the safety of the cooking device 300.

[0060] Reference Figure 2 , Figure 4 and Figure 6 In some embodiments, the air guide cover 100 further includes a second mounting component 39 for mounting the power module 5 , and the second mounting component 39 is located outside the heat dissipation cavity 31 .

[0061] The power module 5 is suitable for connecting to an external power source, and is also electrically connected to the frequency converter 1, and is used to provide current to the frequency converter 1. The power module 5 can also be electrically connected to other components of the cooking device (for example, a fan, a thermostat, an interlocking assembly, a display panel, an upper heating tube, a lower heating tube, a steam generator, and other components).

[0062] Through the above technical solution, the power module 5 can be installed on the air guide cover 100 through the second installation component 39. The cooking device 300 does not need to be provided with a fixed bracket for the power module 5, thereby reducing the number of parts of the cooking device 300, reducing the production cost and installation time, and reducing the cost of the cooking device 300.

[0063] In the related art, when the inverter 1 or the magnetron 2 needs to be repaired, it is necessary to first remove the power module 5 outside the air scoop 100, and then remove the air scoop 100 to expose the inverter 1 and the magnetron 2. In the embodiment of the utility model, the power module 5 is integrated on the air scoop 100. When the inverter 1 or the magnetron 2 needs to be repaired, it is not necessary to remove the power module 5. The air scoop 100 can be directly removed to expose the inverter 1 and the magnetron 2, thereby reducing the repair cost of the inverter 1 and the magnetron 2.

[0065] When installing the power module 5 on the air scoop 100, the power module 5 is first placed on the first support portion 391, and then the fixing connector passes through the power module 5 and matches with the second fixing hole 3911, so as to fix the power module 5 on the air scoop 100. The fixing connector can be a screw or a bolt, which has high connection stability and low cost.

[0066] In the above technical solution, the power module 5 has high connection stability and is easy to install, thereby reducing the assembly cost of the cooking device 300.

[0067] In some embodiments, the air guide cover 100 further includes a second stop portion 392 , and the second stop portion 392 and the first support portion 391 are spaced apart, and a clamping space for the circuit board 51 of the power module 5 is defined between the second stop portion 392 and the first support portion 391 .

[0068] When installing the power module 5 on the air guide cover 100, first place the circuit board 51 of the power module 5 in the clamping space. The stability of the circuit board 51 is improved by clamping the second stop portion 392 and the first support portion 391, so that workers can use fixed connectors to fix the circuit board 51.

[0070] In the above technical solution, the first clamping block 3921 and the second clamping block 3922 at different positions are respectively stopped on the circuit board 51 , so that the stability of the circuit board 51 is further increased.

[0071] Reference Figure 2 , Figure 4 and Figure 6 In some specific embodiments, the circuit board 51 is constructed as a rectangular plate, and the first clamping block 3921 and the second clamping block 3922 are distributed at both ends of the length direction of the rectangular plate, which effectively limits the movement of the circuit board 51 and ensures the stability of the circuit board 51.

The guide surface 3923 is used to guide the circuit board 51, thereby improving the convenience of entering the clamping space.

[0073] For example, in some specific embodiments, the first clamping block 3921 is provided with a guide surface 3923. When installing the power module 5, one end of the circuit board 51 is first inserted between the second clamping block 3922 and the first support portion 391, and then the other end of the circuit board 51 is pressed, so that the other end of the circuit board 51 enters between the first clamping block 3921 and the first support portion 391 under the guidance of the guide surface 3923, thereby improving the convenience of the circuit board 51 entering the clamping space.
