[0047] The technical solutions in the embodiments of the present application will be described clearly and completely below in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0048] As described in the background, in the existing cooking equipment, for the scene of reserving cooking food by the user, in the reservation cooking mode, the inner container is usually at room temperature, lacks an active refrigeration mechanism, and cannot effectively inhibit the deterioration of food materials.

[0049] To solve the above technical problems, the embodiment of the present application provides a cooking device. The cooking device comprises a cooking body, a circuit board assembly, a refrigeration assembly and a valve assembly. The cooking body is provided with an inner container, and the inner container has an internal cavity. The circuit board assembly is arranged at the top of the inner container, and the refrigeration assembly is also arranged at the top of the inner container. The refrigeration assembly is connected with the internal cavity of the inner container through a pipeline assembly to form a closed refrigeration circulation loop. The valve assembly is arranged on the pipeline assembly, and the valve assembly has a first port, a second port and a third port. The first port and the second port are connected in series in the pipeline assembly, and the third port is connected to the area where the circuit board assembly is located through a branch pipeline, so that the gas generated when the refrigeration assembly operates flows through the circuit board assembly and cools the circuit board assembly. In this way, the cooking device provided by the embodiment of the present application realizes rapid cooling of the internal cavity of the inner container through the closed refrigeration circulation loop formed by the refrigeration assembly and the inner container, keeps the food to be cooked in a low-temperature environment, and prevents the food from deteriorating during reservation. In addition, by adding a branch pipeline to the valve assembly of the pipeline assembly, the cold air generated when the refrigeration assembly operates is guided to the circuit board assembly, without the need for additional cooling structure, thereby realizing efficient cooling of the circuit board assembly.

[0050] In order to make the above-mentioned purposes, features and advantages of the embodiments of the present application more obvious and easy to understand, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings. Obviously, the described embodiments are only part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0051] The embodiment of the present application provides a cooking device. Through the closed refrigeration circulation loop formed by the refrigeration assembly and the inner container, the internal cavity of the inner container is rapidly cooled, the food to be cooked is kept in a low-temperature environment, and the food is prevented from deteriorating during reservation. In addition, by adding a branch pipeline to the valve assembly of the pipeline assembly, the cold air generated when the refrigeration assembly operates is guided to the circuit board assembly, without the need for additional cooling structure, thereby realizing efficient cooling of the circuit board assembly. The specific structure of the cooking device provided by the embodiment of the present application will be introduced below with reference to the drawings.

[0052] Reference Figure 1 and Figure 2The embodiment of the present application provides a cooking equipment 100. Wherein the cooking equipment 100 can comprise a cooking body 200, a circuit board assembly 600 and a refrigeration assembly 300. In the embodiment of the present application, the cooking body 200 can be provided with an inner container 210, and the inner container 210 can have an internal cavity 211. It can be understood that the internal cavity 211 of the inner container 210 can be used to accommodate food materials to be processed. In a possible implementation, the circuit board assembly 600 can be arranged on the top of the inner container 210, and the refrigeration assembly 300 can also be arranged on the top of the inner container 210. Wherein the refrigeration assembly 300 can be connected with the internal cavity 211 of the inner container 210 through a pipeline assembly 400, so that the gas generated by the refrigeration assembly 300 can cool the inner container 210, thereby forming a closed refrigeration circulation loop.

[0053] With reference to the above embodiment, Figure 1 On the basis of the above embodiment, the cooking equipment 100 can further comprise a valve assembly 500. Wherein the valve assembly 500 can be arranged on the pipeline assembly 400. In a possible implementation, the valve assembly 500 can have a first port 530, a second port 540 and a third port 550. Wherein two of the first port 530, the second port 540 and the third port 550 can be connected in series in the pipeline assembly 400, and the other port of the first port 530, the second port 540 and the third port 550 can be connected to the circuit board assembly 600.

[0054] Exemplarily, in a possible implementation, the first port 530 and the second port 540 can be connected in series in the pipeline assembly 400, and the third port 550 can be connected to the area where the circuit board assembly 600 is located through a branch pipeline 450, so that the gas generated when the refrigeration assembly 300 operates can flow through the circuit board assembly 600 and cool the circuit board assembly 600.

[0055] In the embodiment of the present application, it can be understood that the cooking equipment 100 provided by the embodiment of the present application combines the refrigeration circulation loop with the heat dissipation requirement of the circuit board 610, and by additionally arranging the branch pipeline 450 on the valve assembly 500, the low-temperature gas generated when the refrigeration assembly 300 operates is guided to the area where the high-heat-density circuit board assembly 600 is located, thereby achieving active and efficient cooling of the key electronic components. Without the need for additional dedicated heat dissipation structure, the operation reliability and service life of the cooking equipment 100 are significantly improved, and the efficient reuse of resources and the optimization of the overall structure of the cooking equipment 100 are achieved.

[0056] With reference to the above embodiment, Figure 1On the basis of the above-mentioned embodiments, the circuit board assembly 600 can further include: the circuit board 610 and the air duct shell 620. Wherein, the air duct shell 620 can be located below the circuit board 610, and the air duct shell 620 has an air duct cavity for gas circulation.

[0057] Wherein, in a possible implementation, the air duct shell 620 can be provided with a through hole 621, and the branch pipeline 450 can be connected with the air duct cavity through the through hole 621, so that the gas generated during the operation of the refrigeration assembly 300 flows into the air duct cavity through the valve assembly 500 and the branch pipeline 450, and the circuit board 610 is cooled.

[0058] In this way, the cold air from the refrigeration assembly 300 can orderly enter the closed air duct cavity and blow to the circuit board 610 in a concentrated and uniform manner, and the cooling directivity is stronger and the efficiency is higher. The uneven cooling and energy waste caused by random diffusion of cold air are avoided, the working temperature of the circuit board 610 is effectively reduced, and the air duct shell 620 can also form a certain physical protection for the circuit board 610 to prevent oil fume and water vapor generated during cooking from directly eroding, thereby enhancing the stability and environmental adaptability of the cooking equipment 100.

[0059] On the basis of the above-mentioned embodiments, in the refrigeration mode, the first port 530, the second port 540 and the third port 550 of the valve assembly 500 are all in the open state, so as to conduct the refrigeration cycle loop. In the non-refrigeration mode, the first port 530, the second port 540 and the third port 550 of the valve assembly 500 are all in the closed state, so as to isolate the inner container 210 from the refrigeration assembly 300.

[0060] In the embodiments of the present application, it can be understood that the valve assembly 500 is arranged at a key position of the pipeline assembly 400, and is used for controlling the conduction or closing of the refrigeration cycle loop. For example, when the valve assembly 500 is opened, the cold air forms a closed loop flow between the inner container 210 and the refrigeration assembly 300. When the valve assembly 500 is closed, the connection path between the inner container 210 and the refrigeration assembly 300 is shut off, preventing external gas or high-temperature steam from entering the refrigeration assembly 300. Through the control of the valve assembly 500, the cooking equipment 100 can switch between the refrigeration mode and the non-refrigeration mode, avoiding the influence of high-temperature gas on the refrigeration assembly 300 in the non-refrigeration state.

[0061] The cooking device 100 provided by the embodiments of the present application realizes efficient utilization of cold air through the closed refrigeration circulation loop formed by the refrigeration assembly 300 and the inner container 210, ensures that the cold air continuously acts on the internal cavity 211 of the inner container 210, and improves the refrigeration efficiency. In combination with the control logic of the valve assembly 500, the cold air is circulated only in the refrigeration mode, further reducing energy consumption. The fresh-keeping time of the food material is significantly prolonged, and the energy consumption of the cooking device 100 during operation is reduced, providing the user with an efficient and energy-saving cooking experience.

[0062] Reference Figure 2 And Figure 4 On the basis of the above-mentioned embodiments, the inner container 210 can be provided with an air inlet 212 on one side and an air outlet 213 on the other side. Correspondingly, the refrigeration shell 310 can be provided with an air outlet 312 on the side close to the air inlet 212, and the refrigeration shell 310 can be provided with an air inlet 313 on the side close to the air outlet 213. It can be understood that, in combination with Figure 1 It can be understood that, in combination with

[0063] In this way, the air inlet 212 and the air outlet 213 are respectively arranged on the two sides of the inner container 210, the air outlet 312 and the air inlet 313 are respectively arranged on the corresponding positions of the refrigeration shell 310 and are in communication with each other, forming a closed gas circulation loop, which ensures that the cold air generated by the refrigeration assembly 300 is efficiently and directionally delivered to the inside of the inner container 210, avoids the loss of cold air to other non-target areas of the cooking device 100 during the delivery process, causes the cooling efficiency to decrease, realizes precise delivery of cold air supply, and improves the energy utilization efficiency.

[0064] Reference Figure 1 On the basis of the above-mentioned embodiments, in one possible implementation, the pipeline assembly 400 can include a first connecting pipe 410, a second connecting pipe 420, a third connecting pipe 430, and a fourth connecting pipe 440. The valve assembly 500 can include a first valve 510 and a second valve 520. It can be understood that the valve assembly 500 is a multi-port connecting device for controlling the flow of gas. Exemplarily, the first valve 510 and the second valve 520 can both be three-way valves, and the embodiments of the present application are not limited thereto.

[0065] The first valve 510 can be disposed between the first connecting pipe 410 and the second connecting pipe 420, and the second valve 520 can be disposed between the third connecting pipe 430 and the fourth connecting pipe 440. In this embodiment, the air inlet 212 of the inner liner 210 is connected to the air outlet 312 of the refrigeration housing 310 in sequence through the first connecting pipe 410, the first valve 510 and the second connecting pipe 420, and the air outlet 213 of the inner liner 210 is connected to the air inlet 313 of the refrigeration housing 310 in sequence through the third connecting pipe 430, the second valve 520 and the fourth connecting pipe 440, thereby forming a refrigeration circulation loop of the cooking device 100.

[0066] In this embodiment, a dual-valve, dual-path control is employed, with a first valve 510 and a second valve 520 respectively installed at the inlet and outlet gas ends, thereby achieving complete isolation or connection of the refrigeration cycle loop. When the cooking device 100 is refrigerating, both the first valve 510 and the second valve 520 are open, resulting in low airflow resistance. When the cooking device 100 is cooking, both the first valve 510 and the second valve 520 are closed, and there is no gas communication between the inner liner 210 and the refrigeration component 300, preventing high-temperature steam or fumes from entering the refrigeration component 300 during cooking, thus avoiding contamination and corrosion.

[0067] In this embodiment, it is understood that the cold air generated by the refrigeration component 300 is transported through the air outlet 312 of the refrigeration housing 310, and sequentially along the second connecting pipe 420, the first valve 510, and the first connecting pipe 410. It then enters the internal cavity 211 of the inner liner 210 through the air inlet 212, directly contacting the food area for rapid cooling. Subsequently, the gas forms high-temperature steam through heat exchange, which is transported through the air outlet 213 of the inner liner 210, and sequentially along the third connecting pipe 430, the second valve 520, and the fourth connecting pipe 440. Finally, it returns to the refrigeration component 300 through the air inlet 313 of the refrigeration housing 310, achieving gas circulation.

[0068] Continue to refer to Figure 1 Based on the above embodiments, at least one of the first valve 510 and the second valve 520 can be located in the top region of the inner liner 210 between the circuit board assembly 600 and the cooling assembly 300. A branch pipe 450 extends from the third port 550 towards the region of the circuit board assembly 600, and the outlet of the branch pipe 450 faces the circuit board 610. Exemplarily, the second valve 520 can be located in the top region of the inner liner 210 between the circuit board assembly 600 and the cooling assembly 300, while the branch pipe 450 extends from the third port 550 of the second valve 520 towards the region of the circuit board assembly 600. This embodiment is not limited in scope.

[0069] In this embodiment, it is understood that at least one valve is positioned at the top of the inner liner 210, in the area between the circuit board assembly 600 and the cooling assembly 300. This arrangement significantly shortens the airflow path for heat dissipation, allowing more cooling capacity to be directly used for heat dissipation of the circuit board 610. Furthermore, the branch pipe 450's outlet is directly facing the circuit board 610, further enhancing the directness and impact of heat dissipation.

[0070] Based on the above embodiments, the front side of the inner pot 210 may have an opening, so that food can be placed inside the inner pot 210 through the opening.

[0071] In this embodiment, with the inner liner 210 as a reference, the direction connecting the left and right sidewalls of the inner liner 210 is the transverse direction, i.e., the first direction. The height direction of the inner liner 210 is the second direction. The side of the inner liner 210 with an open opening is defined as the front side, the side opposite the front side is defined as the rear side, and the longitudinal direction from the front side to the rear side of the inner liner 210 is the third direction. The first direction, the second direction, and the third direction are perpendicular to each other.

[0072] It should be noted that, for ease of description, in the embodiments of this application, the first direction is... Figure 1 The x-direction. The second direction is... Figure 1 The y-direction. The third direction is... Figure 1 The z-direction in the middle.

[0073] Continue to refer to Figure 2 as well as Figure 3 Based on the above embodiments, the refrigeration assembly 300 may further include a refrigeration module 330 and a first fan 320. At least a portion of the refrigeration module 330 may be located within the refrigeration housing 310, and the first fan 320 may also be located within the refrigeration housing 310, with the first fan 320 and the refrigeration module 330 arranged sequentially along a first direction. In one possible implementation, the outlet of the first fan 320 may be connected to the inlet of the refrigeration module 330, and the gas is cooled by the refrigeration module 330. It is understood that the first fan 320 drives the gas to flow within the refrigeration cycle loop, while the refrigeration module 330 cools the flowing gas.

[0074] The cooking device 100 achieves its cooling function through a cooling cycle formed by the inner pot 210 and the cooling module 300. Specifically, the first fan 320 delivers air to the inlet of the cooling module 330. After being cooled within the cooling module 330, the air is then delivered to the inner pot 210 through the outlet of the cooling module 330. The cooled air enters the interior of the inner pot 210, directly contacting the food area for rapid cooling. The sequential arrangement of the first fan 320 and the cooling module 330 along the first direction ensures the continuity of the gas flow path. Simultaneously, the synergistic effect of heat conduction and cold air delivery enhances the temperature regulation capability within the inner pot 210.

[0075] Continue to refer to Figure 2 as well as Figure 3 Based on the above embodiments, the refrigeration module 330 may further include a first fin 332, a second fin 333, and a second fan 334.

[0076] A cold cavity can be formed inside the refrigeration housing 310. The first fan 320, the refrigeration component 331, and the first fin 332 can be disposed in the cold cavity, while the second fan 334 and the second fin 333 can be disposed outside the refrigeration housing 310. The first fin 332 is fitted to the cold end of the refrigeration component 331 to enhance the heat exchange efficiency at the cold end. The second fin 333 is fitted to the hot end of the refrigeration component 331 to enhance the heat dissipation efficiency at the hot end.

[0077] Continue to refer to Figure 2 as well as Figure 3 Based on the above embodiments, the first fin 332, the cooling element 331, the second fin 333, and the second fan 334 can be arranged sequentially along the second direction.

[0078] In this embodiment, the cooling cavity houses a first fan 320, a cooling element 331, and a first fin 332, while a second fan 334 and a second fin 333 are disposed externally. The first fan 320 delivers air into the cooling cavity, where the air is cooled by the combined action of the cold end of the cooling element 331 and the first fin 332. Furthermore, the second fan 334 drives air to flow through the second fin 333, accelerating heat dissipation from the hot end of the cooling element 331. This separation of the cold-end fins inside the cooling cavity and the hot-end fins outside the cooling cavity achieves efficient operation of the cooling element 331.

[0079] Understandably, the separate design of the first fin 332 and the second fin 333 significantly improves the heat exchange efficiency of the cooling component 331. The first fin 332 at the cold end enhances the cold air generation capacity, while the second fin 333 at the hot end, in conjunction with the second fan 334, accelerates heat dissipation, thereby extending the service life of the cooling component 331 and improving the overall cooling efficiency, further optimizing the temperature stability inside the inner liner 210.

[0080] refer to Figure 4 Based on the above embodiments, the cooking device 100 may further include a fan cover 700 and a third fan 710. The fan cover 700 may be disposed on the side wall inside the inner liner 210, while the third fan 710 may be disposed inside the fan cover 700.

[0081] In one possible implementation, the air inlet 720 of the fan shroud 700 can be located at the center of the fan shroud 700, and the air inlet 720 of the fan shroud 700 is connected to the air inlet 212 of the inner liner 210. The exhaust port 730 of the fan shroud 700 is located in the circumferential direction of the fan shroud 700. In this way, the air flowing in from the air inlet 720 of the fan shroud 700 can be fully mixed with the gas flowing in from the air inlet 212 of the inner liner 210, and discharged through the exhaust port 730 of the fan shroud 700.

[0082] Understandably, the air inlet 720 of the fan shroud 700 is connected to the air inlet 212 of the inner liner 210, allowing the cold air and the air in the inner liner 210 to mix thoroughly under the drive of the third fan 710. The mixed airflow is then evenly discharged to all areas of the inner liner 210 through the circumferential exhaust port 730 of the fan shroud 700. This mixing design of cold air and air improves the uniformity of cooling.

[0083] In this way, the fan cover 700 and the third fan 710 solve the problem of cold air potentially blowing directly onto localized food or accumulating in one area. The third fan 710, acting as the internal circulation power source, forcibly agitates the air inside the inner liner 210, ensuring that the newly injected cold air mixes thoroughly with the existing air inside the inner liner 210. The circumferential exhaust port 730 allows the mixed cold air to flow evenly and diffusely in all directions of the inner liner 210, achieving uniform temperature cooling of the internal space of the inner liner 210, avoiding localized overcooling or cooling dead zones, and ensuring that the food is cooled evenly throughout.

[0084] Continue to refer to Figure 4 Based on the above embodiments, the air inlet 212 of the inner liner 210 is disposed inside the fan cover 700, and the air inlet 212 can be located within the projection range of the fan blades of the third fan 710. In this embodiment, the air inlet 212 is directly disposed in the internal space of the fan cover 700, and the position of the air inlet 212 is directly opposite to or very close to the rotation area of ​​the fan blades of the third fan 710.

[0085] Understandably, the cold air supplied from the refrigeration unit 300 can directly enter the intake area of ​​the third fan 710. As the cold air is supplied, it is simultaneously drawn into the third fan 710 and participates in the mixing and diffusion process. This significantly shortens the cold air propagation path, reduces diffusion and temperature loss before reaching the third fan 710, improves cold air utilization and the start-up speed of internal circulation, resulting in a faster cooling response.

[0086] Continue to refer to Figure 2 Based on the above embodiments, the top of the cooking unit 200 may have a heat insulation plate 220. The refrigeration component 300 may be fixedly mounted on the heat insulation plate 220. In one possible implementation, the refrigeration component 300 may include a refrigeration housing 310, and the bottom plate 311 of the refrigeration housing 310 may have a gap with the heat insulation plate 220.

[0087] In the embodiments of this application, it is understood that, exemplarily, the heat insulation plate 220 can be made of high-temperature resistant heat insulation materials such as ceramic fiber and rock wool, thereby effectively blocking the upward conduction of heat during cooking and protecting the upper refrigeration component 300 from high temperatures. The gap between the bottom plate 311 of the refrigeration housing 310 and the heat insulation plate 220 forms an air insulation layer, further reducing heat conduction and providing a certain amount of ventilation and heat dissipation space, preventing heat accumulation at the bottom of the refrigeration component 300, and improving the working reliability and lifespan of the refrigeration component 300 in high-temperature cooking environments.

[0088] Based on the above embodiments, the bottom plate 311 and the outer surface of the periphery of the cooling housing 310 may be covered with a heat insulation structure (not shown in the figure). The material of the heat insulation structure may be the same as that of the heat insulation board 220, or it may be a different material. For example, the heat insulation structure may be made of materials such as polyurethane foam, and this embodiment of the application is not limited thereto.

[0089] In this embodiment, it is understood that the heat insulation structure can completely cover the outer surface of the cooling housing 310. When the cooking device 100 is cooling, the heat insulation structure can significantly reduce heat loss from the cold cavity to the external environment. When the cooking device 100 is cooking, the heat insulation structure can also prevent external high temperatures from being transferred inward. The heat insulation structure improves cooling efficiency, reduces energy consumption, and enhances the safety and aesthetics of the cooking device 100.

[0090] In this embodiment, the cooking device 100 provides rapid cooling of the internal cavity 211 of the inner pot 210 through a closed cooling cycle formed by the cooling component 300 and the inner pot 210, keeping the food to be cooked in a low-temperature environment and preventing the food from spoiling during the preset cooking period. Furthermore, by adding a branch pipe 450 to the valve assembly 500 of the pipe assembly 400, the cold air generated by the cooling component 300 during operation is guided to the circuit board assembly 600, eliminating the need for additional heat dissipation structures and achieving efficient cooling of the circuit board assembly 600.
