Pressure relief structure and electric steamer with same

Abstract

The invention discloses a pressure relief structure which comprises a gravity pressure-maintaining exhausting assembly, a rapid exhausting assembly and a connecting piece. The gravity pressure-maintaining exhausting assembly communicates with the rapid exhausting assembly through the connecting piece. In the cooking process, the gravity pressure-maintaining exhausting assembly relieves pressure inreal time to enable pressure of an inner container to be always maintained in a preset range; when cooking is stopped and rapid pressure relief is required, the rapid exhausting assembly is started to relieve pressure so that a user can safely open a door body, and at the moment, the gravity pressure-maintaining exhausting assembly continues to relieve pressure or is turned off according to pressure of the inner container; in addition, the gravity pressure-maintaining exhausting assembly and the rapid exhausting assembly are structurally combined through the connecting piece, so that the pressure relief structure is simplified.

Description

technical field [0001] The invention belongs to the technical field of kitchen appliances, and in particular relates to a pressure relief structure and an electric steamer using the same. Background technique [0002] At present, the pressure relief method of the high-pressure electric steamer is: the inner tank is equipped with a pressure-limiting valve assembly, which is mainly composed of a pressure-limiting weight and an exhaust pipe. Exhaust, so that the inner tank maintains a certain pressure. Since the exhaust of the pressure limiting valve is discharged from the surroundings of the pressure weight, in order to prevent the steam from flowing into the electrical components in the machine, the exhaust hood is required to form a fixed exhaust channel. The inner tank also needs to Connect the pressure relief solenoid valve so that when the user stops pressure cooking, the solenoid valve can be opened for quick pressure relief; this pressure steamer pressure relief system ...

[0002] At present, the pressure relief method of the high-pressure electric steamer is: the inner tank is equipped with a pressure-limiting valve assembly, which is mainly composed of a pressure-limiting weight and an exhaust pipe. Exhaust, so that the inner tank maintains a certain pressure. Since the exhaust of the pressure limiting valve is discharged from the surrounding of the pressure weight, in order to prevent the steam from flowing into the electrical components in the machine, the exhaust hood needs to form a fixed exhaust channel. The inner tank also needs to Connect the pressure relief solenoid valve so that when the user stops pressure cooking, the solenoid valve can be opened for rapid pressure relief; this pressure steam box pressure relief system has a complex structure, many spare parts, and high cost. There are also spring-type pressure-limiting solenoid valves on the market Pressure relief valve, and the spring and sealing silicone are affected by steam temperature and food grease, and the life is shorter and often shorter
