Cooking appliance with automatic exhaust function

Abstract

The invention relates to the technical field of cooking appliances and in particular relates to a cooking appliance with an automatic exhaust function. The cooking appliance with the automatic exhaust function comprises a cover, an exhaust pipe arranged on the cover, a pressure-limiting valve which sleeves the exhaust port of the exhaust pipe and is used for sealing or unsealing the exhaust port, and a pressure-limiting valve driving device and a control device; the pressure-limiting valve driving device is capable of driving the pressure-limiting valve to move upwards and unseal the export port under the control of the control device. The cooking appliance with the automatic exhaust function is capable of stopping the pressure-limiting valve from sealing the exhaust port by match of the control device and the pressure-limiting valve driving device and thus realizing exhaust of the electric pressure cooker. Potential safety hazards caused by directly operating the pressure-limiting valve by the hands are avoided; meanwhile, the device for realizing automatic exhaust of the electric pressure cooker is simple in structure and convenient to operate.

Description

technical field [0001] The invention relates to the technical field of cooking utensils, in particular to a cooking utensil with an automatic exhaust function. Background technique [0002] Since the electric pressure cooker is in a high-pressure environment during cooking, the user needs to wait for the high-temperature steam in the pot to completely liquefy into water after the electric heating device stops heating before opening the pot cover safely. Generally, the lid of the electric pressure cooker can only be opened after the electric pressure cooker stops heating and waits for a period of time. The exhaust of the existing electric pressure cooker mostly adopts a heavy hammer type pressure limiting valve. By manually rotating the heavy hammer, the heavy hammer moves upward and escapes from the exhaust pipe, thereby To achieve the purpose of exhaust, and then open the lid. [0003] Moreover, in the manual steam exhaust process, there may be a safety problem that the hi...

Problems solved by technology

Then realize the rotation of the weight, so that the weight moves up and away from the exhaust pipe, so as to achieve the purpose of exhausting, but this structure has relatively more movement, and the resistance is too large when used, resulting in poor exhaust effect, and it is necessary to realize automatic exhaust. To prevent the danger of burns caused by manual operation, it is necessary to increase the electric device and change the structure of the weight at the same time. After the structure of the weight is changed, it is easy to cause the weight to be eccentric, and long-term use will affect the sealing.
