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.

Embodiment 1

[0028] like figure 1 , figure 2 , image 3 As shown, the electric pressure cooker of the present invention includes a pot body 100, a pot cover and a control circuit (not shown in the figure), and the pot cover includes a cover body 200 and a cover 6 arranged on the cover body 200. Made and attached to the cover body 200, extending from the middle of the cover body 200 to the side wall of the cover body 200, the inside of the cover 6 is hollow, enclosing a relatively closed installation space with the cover body 200, and the cover 6 is provided with There is a pot cover handle and an exhaust pipe 13 is installed. The exhaust pipe 13 is covered with a gravity hammer 11. Specifically, the exhaust pipe 13 is surrounded by a gravity hammer installation groove, and the gravity hammer 11 is embedded in the gravity hammer. In the groove, it can move up and down along the gravity hammer installation groove. When the electric pressure cooker does not need to exhaust, the gravity ham...

Embodiment 2

[0035] This embodiment is partially improved on the basis of Embodiment 1. In this embodiment, the return spring 9 in Embodiment 1 is omitted, and the push rod 10 resets under the pressure of its own gravity and the gravity hammer 11. At the same time, in order to The push rod 10 can achieve the same technical effect as before in the absence of the return spring 9. This embodiment can also intentionally increase the quality of the push rod 10. Embedding metal materials, etc.

Embodiment 3

[0037] This embodiment simplifies its structure on the basis of Embodiment 1. This embodiment omits the guide column 14, the push rod 10 and the return spring 9 device in Embodiment 1, and the first link of the first connecting rod The two ends 72 are directly connected with the bottom of the gravity hammer 11, and the specific structure is as follows:

[0038] On the side wall of the gravity hammer installation groove, open a groove longitudinally, the second end of the first connecting rod passes through this groove, stretches into the bottom of the gravity hammer 11, when the second end of the first connecting rod goes up During the displacement, the gravity hammer 11 can be directly driven to move upwards for exhaust, and when the exhaust is not needed, the gravity hammer 11 can be reset under the gravity.

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...
