Electric pressure cooker capable of automatically exhausting

Abstract

The invention provides an electric pressure cooker capable of automatically exhausting. The electric pressure cooker comprises a cooker body, a cooker cover and a control circuit, wherein an exhaust pipe and a gravity hammer which is in sealed contact with the exhaust pipe are arranged on the cooker cover; a first connecting rod is additionally arranged on the cooker cover; a ferromagnetic material is arranged at the first end of the first connecting rod; the position, corresponding to the ferromagnetic material, of the cooker body, is provided with an electromagnet which can take a magnetic effect on the ferromagnetic material; the electromagnetic is electrically connected to the control circuit; the second end of the first connecting rod is in transmitted connection to the gravity hammer; and the gravity hammer is displaced directly or indirectly when the second end of the first connecting rod displaces upwards, and the gravity hammer is separated away from the port of the exhaust pipe. By virtue of the electromagnet and a lever linkage device which are mutually matched, the electric pressure cooker can simplify an automatically exhausting structure, shorten a power transmission route, reduce a probability of a jamming phenomenon in a power transmission process and improve product quality.

Description

technical field [0001] The invention relates to the field of cooking utensils, in particular to an electric pressure cooker with an automatic exhaust function. Background technique [0002] A traditional electric pressure cooker generally includes a pot body and a pot cover. The pot body includes a shell, and a control circuit is arranged in the shell. The pot cover is provided with an exhaust pipe and a gravity hammer placed above the exhaust pipe. The exhaust pipe It is in sealing contact with the gravity hammer to prevent the gas in the pot from being discharged from the exhaust pipe. Only when the air pressure generated in the pot overcomes the force of the gravity hammer can it be exhausted. However, during normal use, the gas generated in the pot The air pressure cannot overcome the force of the gravity hammer. At this time, if exhaust is required, it can only be operated manually, that is, the user manually moves the gravity hammer to separate it from the exhaust pipe...

AI Technical Summary

Problems solved by technology

Although the electric pressure cooker with this structure can realize the automatic exhaust function, its structural connection is complicated, and the power transmission route is far away. To overcome the idle travel in the transmission process, it is necessary to accurately calculate the size and installation position of each transmission part, which increases the difficulty of production and processing. In addition, the upper transmission part of the electric pressure cooker is set on the pot cover, while the lower transmission part is set On the pot body, there is a mechanical contact transmission between the upper and lower transmission parts. The lower transmission part must pass through the middle ring to push the upper transmission part. Or the sealing performance between the pot lids is poor, and it is easy to cause water vapor or water droplets to enter the solenoid valve through the through hole on the middle ring, which brings certain safety hazards to the circuit of the solenoid valve in the pot body.
