[0051] In the prior art, the interior of the microwave oven is provided with power devices such as a microwave source and a power source. When the microwave oven is working, air is brought in from the rear side and out from the front side by a fan, so as to cool the power devices, thereby ensuring the reliable operation of the microwave oven. The air outlets of the microwave oven are arranged on the front side of the microwave oven between the door body and the door frame. The number of the air outlets is limited by the size between the door body and the door frame. The air flow rate in the interior of the microwave oven is limited by the number of the air outlets, so that the cooling effect of the power devices in the interior of the microwave oven is not good. In addition, the air outlets are arranged on the front side of the microwave oven. The hot air flowing out of the air outlets directly blows to the user, which affects the user experience.

[0052] After repeated thinking and verification, the inventors find that if the air outlets of the cooking utensil are arranged on the side of the cooking utensil, the number of the air outlets will not be affected by the door body and the door frame on the front side of the cooking utensil. The number of the air outlets can be arranged more, which is beneficial to improve the air flow rate in the cooking utensil and improve the cooling effect of the power devices. In addition, the hot air flowing out of the air outlets will not directly blow to the user, which improves the user experience.

[0053] Therefore, the inventors design a heat dissipation structure and a cooking utensil. The heat dissipation structure comprises a body, a power assembly and a fan. The body has a first side and a third side adjacent to the first side. A door body assembly of the body is arranged on the first side of the body. The body is provided with an air inlet and an air outlet, and the air outlet is located on the third side. The air outlet will not be limited by the door body assembly, and the number of the air outlet can be arranged more. The fan and the power assembly are respectively installed in a cavity of the body. The fan drives air to flow into the cavity from the air inlet, flow through the power assembly, and flow out of the cavity from the air outlet. The air flow rate in the cavity is faster, which improves the cooling effect of the power assembly. In addition, the hot air flowing out of the air outlet will not directly blow to the user, which improves the user experience.

[0054] The technical solutions of the heat dissipation structure and the cooking utensil provided by the embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0055] Referring to Figures 1 to 6 As shown in the drawings, the heat dissipation structure provided by the embodiments of the present application can be used in a microwave oven or a steam-microwave integrated machine, etc. The heat dissipation structure comprises a body 100, a power assembly and a fan 350.

[0056] The body 100 has a chamber 110, and a first side 130 of the body 100 is provided with a door assembly 200. It can be understood that the first side 130 is the front side of the body 100. The body 100 is provided with an air inlet 111, and a third side 150 adjacent to the first side 130 of the body 100 is provided with an air outlet 120. The third side 150 of the body 100 is the side of the body 100. The body 100 further has a second side 140 opposite to the first side 130, that is, the back side of the body 100. The body 100 can be provided with an inner container 400, and the inner container 400 has a cooking cavity 410. After a user opens the door body 220 of the door assembly 200, the user can put food into the cooking cavity 410. The air inlet 111 and the air outlet 120 are both in communication with the chamber 110. The number of the air inlet 111 and the air outlet 120 is multiple respectively, and the number of the air inlet 111 and the air outlet 120 can be set according to the needs of the person skilled in the art, which is not limited herein.

[0057] The power assembly is installed in the chamber 110. Optionally, the power assembly includes a microwave source, and the microwave source can provide microwaves to the cooking cavity 410 of the body 100 to heat the food in the cooking cavity 410.

[0058] The fan 350 is installed in the chamber 110. For example, after the fan 350 is placed in the chamber 110, the fan 350 can be fixed to the body 100 by fasteners. The fan 350 is configured to drive air to flow from the air inlet 111 into the chamber 110, flow through the power assembly, and flow out of the chamber 110 from the air outlet 120.

[0059] In one possible implementation, in the direction of the air flow in the chamber 110, the power assembly and the fan 350 are located between the air inlet 111 and the air outlet 120 of the body 100. The air outlet 120 of the fan 350 can be directed towards the power assembly, and the fan 350 can drive air to blow towards the power assembly when the fan 350 is working to cool the power assembly.

[0060] The heat dissipation structure provided by the embodiment has the air outlet 120 arranged on the side of the body 100. Compared with the prior art in which the air outlet 120 is arranged on the front side of the body 100 between the door frame 210 and the door body 220 of the door assembly 200, the number of the air outlet 120 can be increased, the air flow rate in the chamber 110 can be increased, and the cooling effect of the power device in the chamber 110 is improved. Here, the hot air flowing out of the air outlet 120 does not directly blow towards the user, and the user experience is improved.

[0061] In one embodiment, as shown in Figures 1-4 the door assembly 200 includes a door frame 210, a door body 220, and an operation assembly 230. The door body 220 and the operation assembly 230 are respectively installed on the door frame 210.Figure 1 As shown, the door body 220 and the operation assembly 230 can be arranged on the door frame 210 in a left-right manner, the door body 220 is arranged to the left, and the operation assembly 230 is arranged to the right. The door body 220 is installed on the door frame 210 and can be opened and closed relative to the door frame 210. The operation assembly 230 includes a display panel and a key panel. The display panel can be controlled by a user to control the cooking appliance.

[0062] The air outlet 120 is arranged on the surface of the door frame 210 located at the third side 150, and the air outlet 120 is configured to allow the air flowing out of the air outlet 120 to flow through the operation assembly 230. That is, the air outlet 120 is located on the side of the door frame 210. For example, the air outlet 120 is located on the rear side of the operation assembly 230, so that the air flowing out of the air outlet 120 can flow through the operation assembly 230.

[0063] In this embodiment, the air cooled by the power assembly flows out of the cavity 110 of the body 100 through the air outlet 120 on the side of the door frame 210 and flows to the external environment. Part of the air flowing out of the air outlet 120 can cool and heat the operation assembly 230 of the door body assembly 200, to ensure the reliable operation of the operation assembly 230.

[0064] In a specific embodiment, as shown in Figure 2 and Figure 8 The body 100 has a rear plate 160 away from the door body assembly 200, and the rear plate 160 is provided with an air inlet 111.

[0065] The rear plate 160 of the body 100 is the wall plate of the body 100 located at the second side 140. The air inlet 111 on the rear plate 160 is away from the air outlet 120 on the door body assembly 200. The number of air inlets 111 can be multiple, and the multiple air inlets 111 are arranged in an array on the rear plate 160. The above arrangement can ensure the flow path of the air in the cavity 110, so that the fan 350 can fully heat the components in the cavity 110 when driving the air to flow in the cavity 110.

[0066] As shown in Figure 1 and Figure 3 A plurality of air inlets 111 can also be arranged on the side of the body 100, and the plurality of air inlets 111 can be arranged in a vertical direction. The orthographic projection of the fan 350 on the side of the body 100 at least partially overlaps the plurality of air inlets 111 on the side of the body 100. The air outside the body 100 can also flow to the fan 350 through the air inlets 111 on the side of the body 100. Through the above arrangement, the external air can enter the cavity 110 of the body 100 through the air inlets 111 on the rear plate 160 and the air inlets 111 on the side of the body 100, which is conducive to improving the air flow rate in the cavity 110 and further improving the cooling effect of the power device.

[0067] As shown in Figure 3 and Figure 4 , the number of air outlets 120 is multiple, and the multiple air outlets 120 are arranged in the height direction of the door body assembly 200. For example, the shape of each air outlet 120 can be an oblong shape, and the length direction of the oblong shape is parallel to the flow direction of the air in the chamber 110. The number of air outlets 120 in the present embodiment is not limited, and those skilled in the art can set it according to actual needs.

[0068] Through the above arrangement, the air in the chamber 110 can flow out from the multiple air outlets 120 on the door frame 210, thereby being able to uniformly cool the operating assembly 230 of the door body assembly 200 along the height direction of the door body assembly 200, which is beneficial to improve the cooling uniformity of the operating assembly 230.

[0069] In one embodiment, as shown in Figure 2 , Figure 5 , Figure 7 , Figure 8 and Figure 9 , the power assembly includes a power supply 310 and a solid-state source 320, and the power supply 310 is electrically connected with the solid-state source 320. Among them, the solid-state source 320 is used as a microwave source of the cooking utensil. Compared with the use of a magnetron, the solid-state source 320 uses a full solid-state semiconductor to excite microwave energy, and its frequency, phase and power can be fed back and adjusted in real time during use. Moreover, the service life of the solid-state source 320 is higher and the cost is lower compared with the magnetron. The power supply 310 can be electrically connected with the solid-state source 320 through a cable. After the power supply 310 is electrically connected with the solid-state source 320, the power supply 310 can supply power to the solid-state source 320.

[0070] The air flowing through one of the power supply 310 and the solid-state source 320 is staggered with the other one. That is to say, the air flowing through the power supply 310 does not flow through the solid-state source 320, and the air flowing through the solid-state source 320 does not flow through the power supply 310. The power supply 310 and the solid-state source 320 have no sequence on the air flow path in the chamber 110, and the air flowing in the chamber 110 can simultaneously cool the power supply 310 and the solid-state source 320.

[0071] In one possible implementation, the power supply 310 and the solid-state source 320 can be arranged on the bottom surface of the chamber 110. In another possible implementation, the power supply 310 and the solid-state source 320 can also be arranged in layers.

[0072] Through the above arrangement, the air flowing in the chamber 110 can simultaneously cool the power supply 310 and the solid-state source 320, avoiding the temperature rise of the air after taking away the heat of one of the power supply 310 and the solid-state source 320, which affects the cooling of the other one of the power supply 310 and the solid-state source 320.

[0073] As shown in Figure 7 , a linkage switch 370 is also installed in the cavity 110 of the body 100, and the linkage switch 370 is electrically connected with the solid-state source 320 and the door assembly 200 respectively. When the door body 220 of the door assembly 200 is opened, the linkage switch 370 controls the solid-state source 320 to stop generating microwaves.

[0074] In a possible implementation, as shown in Figure 4 and Figure 5 , a lamp assembly 360 is also installed in the cavity 110 of the body 100, and the lamp assembly 360 can illuminate the inside of the cooking cavity 410. When the fan 350 works, it can also drive air to flow through the lamp assembly 360 to cool the lamp assembly 360.

[0075] In a specific embodiment, as shown in Figure 2 , Figure 5 , Figure 7 , Figure 8 and Figure 9 , the power supply 310 and the solid-state source 320 are arranged in a stack, and the stacking direction of the power supply 310 and the solid-state source 320 is perpendicular to the flow direction of the air in the cavity 110.

[0076] In this case, one of the power supply 310 and the solid-state source 320 is installed above the other, and the fan 350 can drive the air in the cavity to flow horizontally, and the stacking direction of the power supply 310 and the solid-state source 320 is the vertical direction. Specifically, the heat dissipation structure further includes a bracket 330. One of the power supply 310 and the solid-state source 320 is installed on the top of the bracket 330, and the other of the power supply 310 and the solid-state source 320 is installed on the bottom of the bracket 330. The bracket 330 can be a “U”-shaped structure, and the opening of the “U”-shaped structure faces the bottom of the body 100 and is fixed to the body 100. One of the power supply 310 and the solid-state source 320 can be located between the two side walls of the “U”-shaped structure and fixed to the bracket 330, and the other of the power supply 310 and the solid-state source 320 can be placed on the top of the bracket 330 and fixed to the bracket 330.

[0077] Through the above arrangement, the power supply 310 and the solid-state source 320 have no sequence on the air flow path in the cavity 110, and at the same time, the power supply 310 and the solid-state source 320 avoid temporarily using a large space in the horizontal direction, which is beneficial to reduce the size of the heat dissipation structure and the cooking appliance.

[0078] In a possible implementation, the power supply 310 and the solid-state source 320 are arranged in a stacked manner, and the body 100 is provided with a plurality of air outlets 120, and the plurality of air outlets 120 are arranged at intervals along the height direction of the body 100. Through the above arrangement, the air can flow out of the air outlet 120 at the corresponding height more conveniently after flowing through the power supply 310 and the solid-state source 320, which is beneficial to heat dissipation of the power supply 310 and the solid-state source 320.

[0079] In a specific embodiment, as shown in Figure 2 , Figure 5 , Figure 7 , Figure 8 and Figure 9 , the solid-state source 320 is installed above the power supply 310. For example, when the bracket 330 is a “U”-shaped structure, and the opening of the “U”-shaped structure faces the bottom of the body 100 and is fixed to the body 100, the power supply 310 can be located between the two side walls of the “U”-shaped structure, and the solid-state source 320 can be installed on the top of the “U”-shaped structure.

[0080] As can be understood by those skilled in the art, when the power supply 310 and the solid-state source 320 are working, the heat generation of the solid-state source 320 is greater than that of the power supply 310. Due to the upward movement of heat, if the power supply 310 is installed above the solid-state source 320, the heat generated by the solid-state source 320 will heat the power supply 310, affecting the heat dissipation of the solid-state source 320 and the power supply 310. That is, the solid-state source 320 is installed above the power supply 310 to avoid heating the power supply 310 by the solid-state source 320, and to ensure the heat dissipation effect of the solid-state source 320 and the power supply 310.

[0081] As shown in Figure 2 and Figures 6-9 , the body 100 is configured to accommodate the inner container 400 and the antenna 340. The inner container 400 has a cooking cavity 410. For example, the cooking cavity 410 of the inner container 400 and the power assembly are arranged in the body 100 in a left-right manner, the cooking cavity 410 is located on the left side, and the power assembly in the chamber 110 is located on the right side.

[0082] The antenna 340 is used to be connected in the chamber 110 and to the bottom of the inner container 400, the antenna 340 is electrically connected with the solid-state source 320 above the power supply 310, and the emitting end of the antenna 340 is configured to extend into the inside of the inner container 400. Specifically, the antenna 340 is located at the bottom of the inner container 400 and is arranged through the inner container 400, the top end of the antenna 340 extends into the inside of the inner container 400, and the bottom end of the antenna 340 is located outside the inner container 400. The antenna 340 is located at the bottom of the inner container 400, so that the antenna 340 can contact the food material at a close distance, and the heating efficiency and the heating uniformity of the cooking utensil on the food material are improved.

[0083] The antenna 340 can be electrically connected with the solid-state source 320 above the power source 310 through a coaxial cable, one end of the coaxial cable being connected with the bottom end of the antenna 340, and the other end of the coaxial cable being connected with the solid-state source 320. It can be understood by those skilled in the art that the microwaves generated by the solid-state source 320 can be fed into the cooking cavity 410 of the inner container 400 through the antenna 340. In the embodiment, the solid-state source 320 is located above the power source 310, and the antenna 340 passes through the inner container 400 from the bottom of the inner container 400, so as to ensure the heating efficiency and uniformity of the cooking appliance on the food and the heat dissipation effect of the solid-state source 320 and the power source 310.

[0084] Specifically, as shown in Figures 6-9 the bottom of the inner container 400 protrudes downward to form a protruding portion, and the inner wall of the protruding portion defines an accommodating cavity 411. The emitting end of the antenna 340 is located in the accommodating cavity 411.

[0085] Exemplarily, the protruding portion can be formed on the bottom of the inner container 400 by stamping, and the cross-sectional shape of the protruding portion can be a square or a circle, which is not limited herein. The depth of the accommodating cavity 411 is not less than the height of the part of the antenna 340 extending into the inner container 400, that is, the top end of the antenna 340 does not protrude from the accommodating cavity 411.

[0086] In the related art, the antenna 340 is located at the top or side of the inner container 400, which affects the effective volume of the inner container 400, is conspicuous and not aesthetic. In the embodiment, the antenna 340 is located at the bottom of the inner container 400, and the inner container 400 accommodates the part of the antenna 340 extending into the inner container 400 through the accommodating cavity 411, so as to ensure the volume of the cooking cavity 410 of the inner container 400, and reduce the conspicuousness and improve the aesthetic property.

[0087] As shown in Figure 8 in a specific implementation, the cooking appliance further comprises a cover plate 500, the cover plate 500 being sealed between the cooking cavity 410 and the accommodating cavity 411.

[0088] Exemplarily, a glass plate can be used as the cover plate 500, so that microwaves can pass through the cover plate 500 and enter the cooking cavity 410. Figure 8 It is shown that the opening of the accommodating cavity 411 is located at the top of the accommodating cavity 411, and the cover plate 500 is located inside the inner container 400 and seals the opening of the accommodating cavity 411. In a possible implementation, after the cover plate 500 seals the opening of the accommodating cavity 411, glue can be applied between the cover plate 500 and the inner container 400 to fix the cover plate 500 and the inner container 400.

[0089] The cover plate 500 is used to block the opening of the accommodating cavity 411, and the antenna 340 does not affect the user to put the food into the cooking cavity 410, and the antenna 340 does not have a sense of strangeness. The glass plate is used as the antenna 340, and the visibility is good.

[0090] In one specific embodiment, as shown in Figures 6-9 , the number of antennas 340 is two, the two antennas 340 are arranged at intervals, the two antennas 340 are respectively connected with the bottom of the inner container 400, and the emitting ends of the two antennas 340 respectively extend into the inside of the inner container 400.

[0091] The two antennas 340 can be arranged at intervals horizontally, and the interval between the two antennas 340 is not limited in the embodiment, and can be arranged as required by a person skilled in the art. For example, the bottom ends of the two antennas 340 can be respectively electrically connected with the solid-state source 320 through coaxial cables. The microwaves generated by the solid-state source 320 are fed into the cooking cavity 410 through the two antennas 340.

[0092] The number of antennas 340 is set to two, and the phase of the microwaves can be adjusted. When the two antennas 340 emit microwaves at a specific phase difference, the electromagnetic waves generated by the two antennas 340 will interfere in the cooking cavity 410, so that the microwave energy is more uniformly distributed on the food, and the heating uniformity is improved.

[0093] As shown in Figures 1-3 and Figures 6-9 , the body 100 further includes a bottom plate 600 and an outer shell 700. The bottom plate 600 is connected to the bottom of the inner container 400. The outer shell 700 is arranged outside the inner container 400 and is connected with the bottom plate 600. The bottom plate 600 is connected with the inner container 400, and the convex portion of the inner container 400 has an interval with the bottom plate 600, the bottom end of the antenna 340 can be located between the inner container 400 and the bottom plate 600, and the cable between the antenna 340 and the solid-state source 320 can pass through the interval between the convex portion and the bottom plate 600.

[0094] The bottom plate 600, the inner container 400, the outer shell 700 and the door body assembly 200 define a cavity 110. The outer shell 700, the inner container 400 and the bottom plate 600 jointly form a metal shielding structure, which can prevent the microwaves generated by the solid-state source 320 from leaking, and ensure the safety of the cooking appliance.

[0095] In one embodiment, as shown in Figure 2 , Figure 4 and Figure 5As shown, the fan 350 is located on the side of the power assembly away from the first side 130. A projection of the fan 350 along the direction of air flow in the chamber 110 is a first projection, a projection of the power supply 310 along the direction of air flow in the chamber 110 is a second projection, and a projection of the solid-state source 320 along the direction of air flow in the chamber 110 is a third projection. The second projection and the third projection each have an overlapping area with the first projection.

[0096] Specifically, the number of fans 350 is one, and in the direction from the first side 130 to the second side 140, the power supply 310 and the solid-state source 320 are respectively opposite the air outlet 120 of the fan 350. The fan 350 can drive the air flowing in the chamber 110 to simultaneously dissipate heat from the solid-state source 320 and the power supply 310.

[0097] In the related art, the cooking appliance cools the microwave source and the power supply 310 by two fans 350, which is relatively noisy. The cooking appliance provided in this embodiment cools the solid-state source 320 and the power supply 310 simultaneously by one fan 350, which is conducive to reducing the noise of the cooking appliance.

[0098] When the power supply 310 and the solid-state source 320 are arranged in layers by the bracket 330, in the height direction of the cooking appliance, the fan 350 is opposite the top end of the bracket 330, and the air outlet 120 of the fan 350 faces the power supply 310 and the solid-state source 320. The fan 350 is located on the back side of the bracket 330, and the air blown out of the fan 350 can be blown to the solid-state source 320 and the power supply 310, respectively.

[0099] The overlapping area between the second projection and the first projection is smaller than the overlapping area between the third projection and the first projection. That is, the overlapping area between the fan 350 and the solid-state source 320 is larger than the overlapping area between the fan 350 and the power supply 310. Those skilled in the art can set the size of the above two overlapping areas according to the size of the fan 350 and the amount of air driven by the fan 350, which is not limited herein. The above setting allows the fan 350 to drive more air to the solid-state source 320 with higher heat dissipation, so that the solid-state source 320 can be more fully cooled.

[0100] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present application, and not to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that: it can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement to part or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
