Pressure cooker

Abstract

The invention provides a pressure cooker. The pressure cooker comprises a cover body, an exhaust pipe arranged on the cover body and a pressure limiting valve. The pressure limiting valve is arranged at the air exhaust opening of the exhaust pipe in a sleeving manner. The pressure cooker further comprises a limiting device used for attracting or disconnecting with the pressure limiting valve and a controller used for attracting or disconnecting with the pressure limiting valve according to the current working parameters of the pressure cooker. The pressure cooker has the following beneficial effects: a problem in the prior art is solved so that the pressure limiting valve of the pressure cooker is not wrongly operated, thereby avoiding potential safety hazards; safety of the pressure cooker is improved; and a user does not get burned during operation of the pressure cooker due to mal-operation by the user.

Description

technical field

[0001] The invention relates to the technical field of kitchen appliances, in particular to a pressure cooker. Background technique

[0002] The electric pressure cooker has become one of the necessary electrical appliances in the kitchen because it can perform high-pressure cooking, and has the advantages of good cooking effect, energy saving, and high efficiency.

[0003] The working principle of the electric pressure cooker is to use the pressure limiting valve to control the pressure in the pot, so as to achieve the function of regulating pressure and protecting.

[0004] There are currently two schemes for controlling the pressure limiting valve. The first is that the user manually toggles the pressure limiting valve to lift the pressure limiting valve, and the gas in the pot is discharged from the exhaust pipe. This exhaust method has great safety hazards. The user's hand directly contacts the pressure limiting valve, and the high-temperature steam dis...
