Specifically, the cooking appliance 100 may be an electric pressure cooker, or may be other types of cooking appliances 100, such as an electric cooker, which is not limited herein.

The technical scheme of the invention is explained in detail below by taking the electric pressure cooker as an example. The present embodiment is merely exemplary and does not limit the technical scope of the present invention. In addition, the drawings in the embodiments omit unnecessary components and clearly show the technical features of the invention.

The electric pressure cooker further comprises a heating mechanism and a controller, wherein the heating mechanism is used for heating food in the cooking space 30, and the controller is used for controlling the heating mechanism to perform heating work. Specifically, the cooking body 10 includes a chassis 11 and a pot 12, the heating mechanism is disposed on the chassis 11, the pot 12 is connected to the periphery of the chassis 11 and extends toward one side of the cover 20, the cover 20 is disposed on the pot 12, and a cooking space 30 is defined between the cover 20 and the pot 12. More specifically, the pot body 12 includes an outer pot 121 and an inner pot 122, the outer pot 121 is connected to the base plate 11 and defines a receiving cavity therebetween, the inner pot 122 is disposed in the receiving cavity, and the cover 20 is disposed on the pot body 12 and defines a cooking space 30 with the inner pot 122.

In one embodiment, the electric pressure cooker further comprises a thermal bulb (not shown) for monitoring the cooking temperature in the cooking space 30, and when the thermal bulb monitors that the cooking temperature in the cooking space 30 is greater than or equal to a first preset threshold, the controller controls the heating mechanism to be turned off, so as to prevent the heating mechanism from continuously heating and causing the foam in the cooker to overflow.

The inventor researches and discovers that after the heating mechanism is turned off, the residual heat of the heating mechanism can be continuously heated for a while, namely, the risk of foam overflowing still exists even after the heating mechanism is turned off.

Further, the electric pressure cooker further comprises a heat dissipation mechanism 50, wherein the heat dissipation mechanism 50 is arranged on the chassis 11 and used for dissipating heat of food in the cooking space 30 during the cooking process. When the temperature sensing bulb monitors that the cooking temperature in the cooking space 30 is greater than or equal to a first preset threshold value, the controller controls the heating mechanism to be closed and controls the heat dissipation mechanism 50 to be opened, so that the heat dissipation mechanism 50 can counteract the influence of the waste heat of the heating mechanism on the cooking temperature, and the overflow of foam in the pot is avoided.

It should be noted that, the heat dissipation mechanism 50 can be used for dissipating heat of food after cooking, besides dissipating heat during cooking, so as to accelerate heat dissipation of food heat and facilitate opening of the lid.

It is understood that in other embodiments, the heating mechanism and the heat dissipating mechanism 50 may be disposed on other parts of the rice cooker, and are not limited herein.

In one embodiment, the thermal bulb includes a first thermal bulb 41 and a second thermal bulb 42 that are disposed at an interval, and when one of the first thermal bulb 41 and the second thermal bulb 42 detects that the cooking temperature in the cooking space 30 is greater than or equal to a first predetermined threshold, the heating mechanism turns off the heat dissipation mechanism 50 and turns on.

Specifically, a first bulb 41 is provided on the cover 20 for monitoring the temperature of the top of the cooking space 30, and a second bulb 42 is provided on the base plate 11 for monitoring the temperature of the bottom of the cooking space 30. It is understood that, in other embodiments, the positions of the first thermal bulb 41 and the second thermal bulb 42 are not limited.

In other embodiments, when the thermal bulb detects that the cooking temperature in the cooking space 30 is less than or equal to the second preset threshold, the controller controls the heat dissipation mechanism 50 to be turned off and controls the heating mechanism to be turned on. And the second preset threshold is smaller than the first preset threshold. With the above arrangement, when the temperature in the cooking space 30 is reduced to the second preset threshold, the heating mechanism continues to work to continue the cooking work, thereby ensuring that the temperature in the cooking space 30 is always between the second preset threshold and the first preset threshold during the cooking.

It should be noted that the first preset threshold and the second preset threshold may be set as needed, and different first preset thresholds and second preset thresholds may be set for different foods.

Specifically, the heat dissipation medium circulating in the fluid channel 51 may be liquid or gas. More specifically, the fluid passage 51 is a water pipe or an air pipe, and may be used to flow water or gas.

To ensure the heat dissipation effect, the fluid passage 51 is disposed around the chassis 11. It is understood that, in other embodiments, the fluid passage 51 may be disposed in a part of the chassis 11 along the circumferential direction of the chassis 11, and is not limited herein.
