It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only the parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0039] In the description of this embodiment, the terms "upper", "lower", "left", "right" and other directions or positional relationships are based on the directions or positional relationships shown in the drawings, and are only for the convenience of description and simplified operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation of the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0040] In this embodiment, the term "and / or" is only a description of the association relationship of the associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in the present utility model generally indicates that the associated objects before and after are in an "or" relationship.

[0041] In the embodiments of the present invention, the same reference numerals represent the same components, and for the sake of brevity, detailed descriptions of the same components are omitted in different embodiments.

[0042] like Figure 1 As shown, this embodiment provides a cooking device, including an inner pot 1, a microwave transmitting module 2, a heat dissipation duct 3 and a body 10. The inner pot 1 is installed inside the body 10, and the inner pot 1 has a take-in and put-out opening, and a door body (not shown) is provided on one side of the take-in and put-out opening, and the door body can be opened or closed to take food in and put food through the take-in and put-out opening. The microwave transmitting module 2 and the heat dissipation duct 3 are also installed inside the body 10.

[0043] Specifically, the microwave transmitting module 2 is used to transmit microwaves, and the microwaves emitted by the microwave transmitting module 2 can be transmitted to the inner pot 1 to cook the food in the inner pot 1. The heat dissipation duct 3 is used to flow gas, and the airflow in the heat dissipation duct 3 is specified to flow along a first direction. The microwave transmitting module 2 and the heat dissipation duct 3 are both located above the inner pot 1, and the microwave transmitting module 2 is located on one side of the heat dissipation duct 3 along a second direction, and the second direction is perpendicular to the first direction.

[0044] In the cooking device provided in this embodiment, the gas flow direction in the heat dissipation duct 3 is a first direction, and the microwave transmitting module 2 is located on one side of the heat dissipation duct 3 along the second direction. The gas flow direction in the heat dissipation duct 3 is the front-to-back direction of the cooking device, the second direction perpendicular to the first direction is the left-to-right direction of the cooking device, and the height direction of the cooking device is the third direction. That is, the microwave transmitting module 2 is arranged on the left or right side of the heat dissipation duct 3. There is no need to reserve space for arranging the microwave transmitting module 2 on the rear side of the heat dissipation duct 3, so that the heat dissipation duct 3 can be extended to the rear side of the cooking device by a sufficient length, ensuring that the heat dissipation duct 3 has a large internal space, avoiding the defect of insufficient front-to-back dimensions of the heat dissipation duct 3 due to the arrangement of the microwave transmitting module 2 on the rear side, and there is no need to increase the size of the cooking device in the front-to-back direction in order to arrange the microwave transmitting module 2. In the cooking device, the microwave solid-state source is arranged on the side (left or right) of the heat dissipation duct 3 where there is a space for arrangement, so that the layout of the microwave solid-state source and the heat dissipation duct 3 is rationalized, the space on the top of the inner pot 1 is fully utilized, the size of the cooking device in the front-to-back direction is reduced, and it is conducive to the miniaturization design of the cooking device and the cost reduction.

[0045] Furthermore, the air in the heat dissipation duct 3 flows from the rear side to the front side. The door body is located at the front side of the cooking device, and a cavity is provided inside the door body. The heat dissipation duct 3 is connected with the cavity inside the door body, so that the air flow can flow through the cavity inside the door body to take away the heat on the door body during the cooking process.

[0046] See also Figure 1 and Figure 2 The cooking device further includes a fan 4, which is located at the rear side of the microwave transmitting module 2 and the heat dissipation duct 3, that is, the door body and the fan 4 are arranged on both sides of the heat dissipation duct 3 along the first direction, and the layout is reasonable. The air outlet of the fan 4 faces the air inlet of the microwave transmitting module 2 and the heat dissipation duct 3. That is, the airflow blown out of the air outlet of the fan 4 can blow toward the air inlet of the microwave transmitting module 2 and the heat dissipation duct 3, so as to cool down the microwave transmitting module 2 and the heat dissipation duct 3 at the same time, reduce the number of fans 4 used under the premise of rationalizing the layout, and reduce the production cost.

[0047] In this embodiment, the length direction of the fan 4 extends along the second direction, so that a part of its air outlet faces the microwave transmitting module 2 , and another part faces the heat dissipation duct 3 .

[0048] In other embodiments, a separate fan 4 may be provided for the microwave transmitting module 2 and the heat dissipation duct 3 , respectively. The two fans 4 cool down and dissipate heat for the microwave transmitting module 2 and the heat dissipation duct 3 , respectively.

[0049] See also Figure 1 and Figure 2The cooking device further comprises a microwave transmission element 7. A microwave inlet is provided on the inner pot 1, and the microwave transmission element 7 is installed at the microwave inlet. The microwave transmitting module 2 is provided with a microwave transmitting port 21. The microwave transmission element 7 penetrates the heat dissipation duct 3 and is connected to the microwave transmitting port 21. The microwaves emitted by the microwave transmitting port 21 are transmitted to the inner pot 1 through the microwave transmission element 7. That is, the microwave transmission element 7 penetrates the heat dissipation duct 3 and extends to the microwave inlet of the inner pot 1. On the one hand, the space at the top of the inner pot 1 can be saved, and there is no need to reserve a layout space for the microwave transmission element 7 outside the heat dissipation duct 3. On the other hand, due to the airflow in the heat dissipation duct 3, the microwave transmission element 7 located in the heat dissipation duct 3 can quickly dissipate heat and cool down under the action of the airflow, thereby avoiding excessive temperature affecting the transmission of microwaves.

[0050] See also Figure 2 and Figure 3 The cooking device further includes an exhaust pipe 8, one end of which is provided with an air inlet, which is communicated with the inner pot 1, and the other end of which is provided with an exhaust port, which is located in the heat dissipation duct 3. During the cooking process, the pressure in the inner pot 1 increases, and the oil smoke, steam, etc. in the inner pot 1 are discharged into the heat dissipation duct 3 through the exhaust pipe 8, and are discharged from the cooking device under the action of the airflow in the heat dissipation duct 3.

[0051] In this embodiment, see Figure 3 The microwave transmission element 7, the exhaust port of the exhaust pipe 8 and the air outlet of the heat dissipation duct 3 are sequentially arranged along the air flow direction in the heat dissipation duct 3. Figure 5 That is, the exhaust port of the exhaust pipe 8 is located downstream of the microwave transmission element 7. With this arrangement, the oil smoke and steam discharged from the exhaust pipe 8 flow to the downstream of the microwave transmission element 7 and are directly discharged toward the air duct outlet 31, rather than toward the microwave transmission element 7, thereby preventing the microwave transmission element 7 from being contaminated or damp, and avoiding affecting the microwave transmission performance of the microwave transmission element 7.

[0052] See also Figure 1 , Figure 2 as well as Figure 4 The cooking device further includes a coaxial cable 9. One end of the coaxial cable 9 is connected to the microwave emitting port 21, and the other end is connected to one end of the microwave transmission component 7 extending out of the heat dissipation duct 3. The microwave emitted by the microwave emitting port 21 is transmitted to the microwave transmission component 7 through the coaxial cable 9, and the microwave transmission component 7 then transmits the microwave to the inner pot 1. Specifically, a cable connector 70 is provided at the microwave emitting port 21, and one end of the coaxial cable 9 is connected to the cable connector 70 at the microwave emitting port 21. The microwave transmission component 7 includes a conductive structure and a cable connector 70 provided on the conductive structure. The other end of the coaxial cable 9 is connected to the conductive structure of the microwave transmission component 7 through the cable connector 70, and the conductive structure transmits the microwave to the inner pot 1.

[0053] The microwave emitting port 21 and the end of the microwave transmission element 7 extending out of the heat dissipation duct 3 are both outside the heat dissipation duct 3, that is, the portion of the cable connector 70 of the microwave transmission element 7 for connecting with the coaxial cable 9 is outside the heat dissipation duct 3. Therefore, the coaxial cable 9 can be connected outside the heat dissipation duct 3. On the one hand, there is no need to connect the coaxial cable 9 and the microwave transmission element 7 inside the heat dissipation duct 3, making the assembly process simpler and easier to operate; on the other hand, the oil smoke, steam and other substances in the heat dissipation duct 3 will not adhere to the connector of the coaxial cable 9, avoiding damage to the coaxial cable 9 with a delicate structure.

[0054] In some embodiments, the cross-sectional area of ​​the heat dissipation duct 3 at the microwave transmission element 7 is smaller than the cross-sectional area of ​​the heat dissipation duct 3 upstream of the microwave transmission element 7. That is, the cross-sectional area of ​​the heat dissipation duct 3 gradually decreases from the air inlet to the microwave transmission element 7, so that the airflow pressure and flow rate of the heat dissipation duct 3 at the position of the microwave transmission element 7 will increase, which is conducive to the rapid heat dissipation of the microwave transmission element 7 and avoids excessive temperature rise of the microwave transmission element 7. Figure 5 The shell of the heat dissipation duct 3 is provided with a transmission member insertion position 32, which is arranged opposite to the microwave inlet on the inner pot 1, and the microwave transmission member 7 penetrates the transmission member insertion position 32. The cross-sectional area of ​​the heat dissipation duct 3 at the transmission member insertion position 32 is smaller than the cross-sectional area at the air inlet, that is, the thickness of the heat dissipation duct 3 is smaller at the transmission member insertion position 32. When the microwave transmission member 7 is installed, the microwave transmission member 7 can penetrate the heat dissipation duct 3, avoiding the phenomenon that the cable connector 70 at the upper end of the microwave transmission member 7 cannot extend out of the heat dissipation duct 3.

[0055] Specifically, the cross-sectional area at the air inlet of the heat dissipation duct 3 is larger than the cross-sectional area at one end of the air outlet 31 of the duct, and the cross-sectional area of ​​the heat dissipation duct 3 gradually decreases from the rear end to the front end.

[0056] See also Figure 1 and Figure 2 The cooking device further comprises a DC power supply 5, which is electrically connected to the microwave transmitting module 2. Specifically, the DC power supply 5 is electrically connected to the microwave transmitting module 2 through a wiring harness. The alternating current is converted by the AC-DC module of the DC power supply 5 and transmitted to the microwave transmitting module 2 for power supply. The microwaves emitted by the microwave transmitting port 21 of the microwave transmitting module 2 are transmitted to the microwave transmission element 7 through the coaxial cable 9, and the microwave transmission element 7 then transmits the microwaves to the inner pot 1. Specifically, the DC power supply 5 is located above the heat dissipation duct 3. On the one hand, the DC power supply 5 and the heat dissipation duct 3 are stacked in the height direction, which can make full use of the space above the heat dissipation duct 3. Moreover, the temperature at the location of the heat dissipation duct 3 is relatively low. Setting the DC power supply 5 above the heat dissipation duct 3 is helpful for heat dissipation and cooling of the DC power supply 5. On the other hand, the DC power supply 5 is arranged above the heat dissipation duct 3 rather than inside the heat dissipation duct 3, which can prevent the DC power supply 5 from being contaminated or soaked by substances such as oil smoke and steam, and prevent the DC power supply 5 from being damaged.

[0057] Exemplarily, the microwave transmitting module 2 is a microwave solid-state source, which has two microwave transmitting ports 21. Correspondingly, the cooking device is provided with two coaxial cables 9 and two microwave transmission elements 7, and each of the two microwave transmission elements 7 is connected to the corresponding microwave transmitting port 21 through a coaxial cable 9.

[0058] The cooking device further includes a control panel 6, which is communicatively connected with the microwave transmitting module 2 and is located above the heat dissipation duct 3. On the one hand, the control panel 6 and the heat dissipation duct 3 are stacked in the height direction, which can make full use of the space above the heat dissipation duct 3, and the temperature at the location of the heat dissipation duct 3 is relatively low, so arranging the control panel 6 above the heat dissipation duct 3 is helpful for heat dissipation and cooling of the control panel 6. On the other hand, the control panel 6 is arranged above the heat dissipation duct 3 rather than inside the heat dissipation duct 3, which can prevent the control panel 6 from being polluted or soaked by substances such as oil smoke and steam, and prevent the control panel 6 from being damaged.

[0059] Furthermore, the DC power supply 5 and the control board 6 are distributed along the first direction to fully utilize the space above the heat dissipation duct 3 along the front-to-back direction. More specifically, the DC power supply 5 is arranged on the front side of the control board 6. Figure 5 Since the cross-sectional area of ​​the heat dissipation duct 3 gradually decreases from the rear end to the front end, the space above the heat dissipation duct 3 on the front side is larger, and the DC power supply 5 is thicker than the control board 6. The height space required for arranging the DC power supply 5 is larger than the height space required for the control board 6. Therefore, arranging the DC power supply 5 on the front side of the control board 6 makes space utilization more reasonable.

[0060] Furthermore, the DC power supply 5 and the control board 6 are respectively located on both sides of the microwave transmission element 7. The microwave transmission element 7 is approximately located in the middle of the inner pot 1, so that the microwaves transmitted to the inner pot 1 are more uniform. The microwave transmission element 7 has space on both sides along the first direction, which can be used to arrange the DC power supply 5 and the control board 6 respectively, further increasing the rationality of the layout.

[0061] See also Figure 5 An installation space 20 is defined between the top of the inner tank 1 and the body 10 , and the heat dissipation duct 3 , the microwave transmitting module 2 , the DC power supply 5 , the control board 6 , etc. are all located in the installation space 20 .

[0062] In some embodiments, such as Figure 4 and Figure 5 As shown, the conductive structure of the microwave transmission element 7 is an antenna 71 . The microwaves emitted by the microwave emission module 2 are transmitted to the antenna 71 via the coaxial cable 9 , and the antenna 71 further radiates the microwaves into the inner pot 1 .

[0063] In other embodiments, the conduction structure of the microwave transmission element 7 can be a waveguide tube, on which a cable connector 70 is provided. The microwaves emitted by the microwave transmitting module 2 are transmitted directly into the waveguide tube through a coaxial cable 9 and reflected into the inner tank 1 through the inner wall of the waveguide tube.

[0064] Optionally, the two microwave transmission components 7 can be located on the same wall of the inner pot 1 or on different walls of the inner pot 1. For example, the two microwave transmission components 7 are both installed on the top wall of the inner pot 1, or one microwave transmission component 7 is installed on the top wall of the inner pot 1, and the other microwave transmission component 7 is installed on the left wall or the right wall of the inner pot 1.

[0065] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention. It is not necessary and impossible to list all implementation methods here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the scope of protection of the claims of the present invention.
