In addition, the present invention does not specifically limit how the cooling water of the liquid storage device 130 enters the cooling pipeline 140. For example, in a specific embodiment, the liquid storage device 130 is disposed in the pot body 100 of the cooking appliance, before cooking, a user adds an appropriate amount of cooling water into the liquid storage device 130, and after cooking is finished, the water pump pumps the cooling water in the liquid storage device 130 into the cooling pipeline 140, so that the cooling water circulates between the liquid storage device 130 and the cooling pipeline 140; in another specific embodiment, the liquid storage device 130 is disposed outside the pot body 100 of the cooking appliance, the cooling pipeline 140 is not provided with a water pump, and when cooking is to be finished, a user manually adds cooling water into the liquid storage device 130, and the cooling water is filled into the cooling pipeline 140 by gravity.

As a preferred embodiment of the present invention, referring to fig. 3 and 4, the cooling pipeline 140 includes a cooling section 141, and a water outlet end 142 and a water inlet end 143 disposed at an end of the cooling section 141, wherein the water outlet end 142 and the water inlet end 143 are respectively communicated with the liquid storage device 130.

Further, the cooling pipe 140 is an annular pipe with a circular cross section, which facilitates the flow of cooling water in the cooling pipe 140 and facilitates the manufacturing of the cooling pipe 140. Of course, it is understood that the cooling circuit 140 may take other shapes, such as a spiral shape, an S-shape, etc.

In one embodiment, the outlet end 142 and the inlet end 143 communicate directly with the reservoir 130. Through directly communicating water outlet end 142 and water inlet end 143 with stock solution device 130, reduced the length of cooling tube 140, even do not set up the water pump on cooling tube 140, the water in cooling tube 140 still can be better carries out the heat transfer with the cooling water in stock solution device 130, and then makes cooking utensil's structure compacter, also reduction in production cost simultaneously.

The water pump 150 is provided to improve the fluidity of the cooling water. Because the water pump 150 can pump the cooling water from the liquid storage device 130 to the conveying section 144 and the cooling section 141 continuously, and then the cooling water flows out from the backflow section 145, the cooling water can circulate alternately between the liquid storage device 130 and the cooling pipeline 140, the cooling section 141 is not easy to accumulate a large amount of heat in a short time, so that the cooling water in the cooling pipeline 140 can keep a lower temperature, the heat absorption capacity of the cooling water is ensured, the cooling water can effectively perform rapid and stable cooling and heat dissipation on the heating plate 120, the cooling efficiency of the cooling pipeline 140 is improved, and the temperature difference between the inner wall and the outer wall of the inner container 110 can be rapidly generated, so that the water vapor in the gaps of the rice and on the upper part of the inner container can be rapidly condensed to form a water film, and the non-sticking effect of the uncoated inner container is better.

The form of the water pump 150 is not particularly limited in the present invention. Preferably, the water pumps 150 are arranged on the conveying section 144 and the return section 145, and the water pumps 150 are electromagnetic pumps, so that the cooling pipeline 140 can be controlled by the water pumps 150, and the cooling water is prevented from entering the cooling pipeline 140 and being heated by the heat-generating plate 120 in the cooking process. After the rice is cooked, the heating plate stops working, the control device starts the electromagnetic pump to circulate and reciprocate the cooling water in the liquid storage device 130 in the cooling pipeline 140 to cool the heating plate 120 to the set temperature value, manual intervention is not needed, and the use is convenient.
