[0028] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work shall fall within the scope of protection of the present invention.

[0029] To facilitate understanding of this embodiment, the application scenarios and design concepts of the embodiment of this application are briefly introduced below.

[0030] Cooking appliances experience a temperature rise during operation. If this temperature rise isn't effectively controlled, the appliance can overheat and potentially damage. Existing technologies use external condensing water tanks to achieve water cooling. This requires pre-installed piping, resulting in a complex structure, inconvenience in movement, and high production costs.

[0031] Example 1

[0032] The present application provides a water cooling structure for a cooking appliance, such as Figure 1As shown, it includes: a water tank 1, a water pump 2, and a heat dissipation pipeline 3 which are connected in sequence by pipelines.

[0033] The water tank 1 is filled with condensed water, and the water pump 2 pumps out the condensed water and directs it to the heat dissipation pipe 3 to cool the control mechanism 5 in the cooking appliance in contact with the heat dissipation pipe 3 and then flows back to the water tank 1 .

[0034] The water tank 1 is arranged on the cooking appliance. The water tank 1 is connected to the cooking space inside the cooking appliance through a valve to form a water supply pipeline for supplying water to the cooking space.

[0035] The water-cooling structure for cooking appliances provided herein uses a water pump 2 to pump condensed water from a water tank 1 and direct it to a heat dissipation pipe 3. This heat dissipation pipe 3 contacts a control mechanism 5. The condensed water in the pipe exchanges heat with the higher-temperature control mechanism 5, cooling the control mechanism 5. The condensed water, after heat exchange, heats up and flows back into the water tank 1. Because the water tank 1 is connected to the cooking space via a valve, water can be added to the cooking space when the valve is opened, ensuring hydration during cooking.

[0036] As an implementable approach, the pipelines in the water cooling structure and the water supply structure are independent of each other and share a water storage tank 1. In this way, there is no need to set up a separate condensing water tank, which can simplify the structure.

[0037] As another feasible method, the pipelines in the water cooling structure and the water supply structure partially overlap. Specifically, in combination with the first aspect, the valve is a three-way valve 4, the first port 41 of the three-way valve 4 is connected to the heat dissipation pipeline 3, the second port 42 of the three-way valve 4 is connected to the water tank 1, and the third port 43 of the three-way valve 4 is connected to the cooking space.

[0038] The flow direction of the water in the connecting pipeline can be adjusted by the three-way valve 4.

[0039] When the first port 41 and the second port 42 are connected, the water cooling structure is turned on, and the water pump 2 is started to pump out the condensed water in the water tank 1. The pumped condensed water flows in the pipeline and flows to the heat dissipation pipeline 3 to exchange heat with the control mechanism 5. The heated condensed water flows back to the water tank 1 through the first port 41 and the second port 42. The heated condensed water is mixed with the original condensed water, thereby increasing the overall temperature of the condensed water. When replenishing water to the cooking space, compared with the method of directly replenishing condensed water, energy consumption can be reduced, the impact on the cooking temperature is small, and the cooking effect is better.

[0040] When the first port 41 and the third port 43 are connected, the condensed water after heat exchange is heated and injected into the cooking space for cooking water replenishment.

[0041] When the second port 42 and the third port 43 are connected, the condensed water in the water storage tank 1 flows into the cooking space for replenishing water for cooking.

[0042] In combination with the first aspect: the heat dissipation pipeline 3 includes a heat dissipation fin and an insulated water pipe surrounding the heat dissipation fin.

[0043] Specifically, the heat sink is located in the area where the control mechanism 5 is located. Several circles of insulated water pipes are wrapped around the outside of the heat sink. The condensed water in the insulated water pipes exchanges heat with the area where the control mechanism 5 is located to reduce the temperature of the control mechanism 5.

[0044] In combination with the first aspect, the control mechanism 5 is connected to a temperature sensor 6 , and the temperature sensor 6 is used to detect a temperature value of the control mechanism 5 and transmit the temperature value to the control mechanism 5 .

[0045] The temperature of the control mechanism 5 during its operation is collected by the temperature sensor 6 and transmitted to the control mechanism 5 to determine whether the current temperature of the control mechanism 5 meets the preset requirements.

[0046] The temperature sensor 6 can be fixed to the surface of the control mechanism 5 by welding, clamping, etc., or can be embedded in a circuit board in the control mechanism 5, or be provided on one side of the control mechanism 5 and electrically connected to the control mechanism 5. All of the above methods are applicable and are not limited here.

[0047] In combination with the first aspect, the water pump 2 and the three-way valve 4 are respectively connected to the control mechanism 5 .

[0048] Combine Figure 2 As shown, the operating states of the water pump 2 and three-way valve 4 are controlled by the control mechanism 5. When the current temperature of the control mechanism 5 does not meet the preset requirements, the water pump 2 is controlled to pump out condensed water to automatically cool the control mechanism 5. Furthermore, by controlling the operating state of the three-way valve 4, the flow direction of the heated condensed water can be changed, and water replenishment can be provided for cooking when needed.

[0049] In a second aspect, an embodiment of the present application provides a cooking utensil, comprising the above-mentioned water cooling structure applied to the cooking utensil.

[0050] In combination with the second aspect, the cooking apparatus comprises a main body 7 and a cover 8 , and the cover 8 is opened or closed to adjust the open or closed state of the cooking space in the main body 7 .

[0051] In combination with the second aspect, the water storage tank 1 in the water cooling structure applied to the cooking utensil is provided on the cover 8 .

[0052] In this embodiment, the water tank 1 is arranged on the cover body 8, and a valve is provided at the bottom of the water tank 1. By adjusting the opening and closing angle of the valve, the flow rate of condensed water in the water tank 1 into the cooking space in the appliance body 7 can be adjusted. The condensed water can also flow in the pipeline under the action of the water pump 2 to perform heat exchange with the control mechanism 5 outside the pipeline. Since the condensed water and the control mechanism 5 are separated by the pipeline, the condensed water will not be polluted, so the condensed water can still be used to pass into the cooking space for water replenishment. In addition, the condensed water after heat exchange is heated and heated. Compared with the method of directly replenishing condensed water, the temperature of the water flow replenished in this application is relatively higher. In this way, it does not need to be heated for a long time after replenishing water during the cooking process, which can reduce energy consumption, and the warm water has little effect on the taste of food, so that the cooking effect is good.

[0053] For example, in traditional cooking methods, condensed water is directly added, mixing with the warmer water in the cooking space, lowering the temperature of the ingredients in the cooking space. This increases the energy consumption required to heat the ingredients. For example, beef, after adding cold water, becomes firm and difficult to absorb into the food during subsequent cooking, resulting in a poor taste. In contrast, in this embodiment, the addition of warm water after heat exchange reduces the temperature drop of the cooking liquid in the cooking space, requiring relatively less energy to reach the preset cooking temperature, and minimizing the impact on the taste of the ingredients.

[0054] Combine Figure 4 As shown, a handle 9 is provided on the cover of the cooking utensil, and the cover 8 can be opened by pulling the handle 9 .

[0055] In combination with the second aspect, the cooking utensil is an automatic cooking steamer, a frying pan, or an all-in-one cooking machine.

[0056] It is understandable that in the actual application process, the following methods can be used to control the cooking utensils, combined with Figure 3 As shown, the method includes:

[0057] S110, obtaining a first temperature value of the control mechanism 5 in the cooking appliance.

[0058] S120: Determine whether the first temperature value is greater than a preset first temperature threshold.

[0059] If so, execute step S130.

[0060] S130 , turning on the water pump in the water cooling mechanism to start the water cooling mechanism to cool down the control mechanism 5 .

[0061] In this embodiment, by comparing the obtained first temperature value of the control mechanism 5 with the preset first temperature threshold, it is determined whether the operating temperature of the control mechanism 5 is too high. When the operating temperature of the control mechanism 5 is too high, the water cooling mechanism is started to cool the control mechanism 5 through heat exchange, so as to reduce the working failure caused by overheating of the control mechanism 5 and improve the stability and continuity of the cooking appliance.

[0062] It can be understood that when the first temperature value of the control mechanism 5 is less than or equal to the preset first temperature threshold, it means that the operating temperature of the control mechanism 5 is within the normal temperature range, and the operating temperature monitoring can be continued.

[0063] After step S130, the method further includes:

[0064] S140 , after a preset first time period, obtaining a second temperature value of the control mechanism 5 detected by the temperature sensor.

[0065] After the water cooling is turned on to cool the control mechanism 5 for a first period of time, the temperature of the control mechanism 5 is collected to obtain a second temperature value of the control mechanism 5 .

[0066] S150: Determine whether the second temperature value is less than a preset second temperature threshold, wherein the second temperature threshold is less than the first temperature threshold.

[0067] It is determined whether the second temperature value after the cooling process is less than the second temperature threshold value to determine whether the safe range has been reached, that is, whether the operating temperature of the control mechanism 5 has dropped significantly after the cooling process.

[0068] If so, execute step S160.

[0069] S160: Determine that the current temperature of the control mechanism 5 is within a safe range, and turn off the water pump to stop the operation of the water cooling structure.

[0070] If the operating temperature of the control mechanism 5 has dropped significantly to a safe range after the cooling process, and its operating temperature quickly rises above the first temperature threshold in a short period of time, the water cooling structure can be turned off and the temperature of the control mechanism 5 can be continuously monitored.

[0071] After step S150, the method further includes:

[0072] If not, execute steps S170-S180.

[0073] At this time, the operating temperature of the control mechanism 5 has not dropped significantly to the safe range after the cooling treatment, that is, the temperature is still too high. There are two situations: its operating temperature has not dropped to the normal range, or the operating temperature has dropped to the normal range but has not reached the safe range.

[0074] S170 , collecting a third temperature value of the control mechanism 5 at first time intervals until the third temperature value is less than a second temperature threshold.

[0075] If the temperature is still high, the water-cooling structure is continuously operated to continue heat exchange. Then, steps S140-S150 are repeated. That is, after a first period of time, the temperature is collected again and compared with the second temperature threshold. If the temperature is still not less than the second temperature threshold, the water-cooling structure is continuously operated for a second first period of time, and the temperature is collected again and compared with the second temperature threshold. The above steps are repeated until the obtained temperature value is less than the second temperature threshold and falls within a safe range.

[0076] S180, controlling the water pump to shut down to stop the operation of the water cooling structure.

[0077] Likewise, after the temperature of the control mechanism 5 enters a safe range, heat exchange and cooling are stopped.

[0078] In conjunction with the third aspect, the method further includes:

[0079] S210 , in response to a water replenishment instruction, controlling the three-way valve to connect the pipeline between the water storage tank and the cooking space to replenish water into the cooking space.

[0080] In a third aspect, the present application provides a control system for a cooking appliance, comprising a master control unit and at least one of the above-mentioned cooking appliances, wherein the master control unit is communicatively connected with a control mechanism in the cooking appliance.
