Steam exhaust device, electric pressure cooker and exhaust control method

Abstract

The invention relates to a steam exhaust device, an electric pressure cooker and an exhaust control method. The steam exhaust device comprises an exhaust assembly which consists of an on-off mechanism and an exhaust column; the exhaust column is equipped with a first exhaust hole and a second exhaust hole, wherein the first exhaust hole is communicated with a high pressure cavity in a vessel, and while the second exhaust hole is communicated with the outside; the on-off mechanism is arranged at one side of the exhaust column and can switch the on and off states; when in the on state, the on-off mechanism can form a cavity with the exhaust column, and the first exhaust hole can be communicated with the second exhaust hole through the cavity so as to guide the high pressure cavity in the vessel to exhaust steam to the outside, and a first exhaust channel can also be formed; when in the off state, the communication mechanism can separate the first exhaust hole from the second exhaust hole, so as to stop the high pressure cavity in the vessel exhausting steam to the outside. With the adoption of the steam exhaust device and the exhaust control method, the exhaust-caused noise can be reduced, and the risk of steam leakage can be decreased.

Description

technical field [0001] The invention relates to the field of daily necessities, in particular to a steam discharge device, an electric pressure cooker and an exhaust control method. Background technique [0002] Since the electric pressure cooker uses pressure for cooking, the cooking time is greatly shortened, and it has become a more and more widely used kitchen appliance. The electric pressure cooker adopts a sealed structure between the lid and the pot body, which can maintain a high-pressure state during the cooking process. After cooking, the high-pressure water vapor in the pot body is released through the exhaust device. [0003] The electric pressure cooker in the prior art mainly achieves the purpose of exhausting by manually pushing or pushing the pressure limiting valve by a solenoid valve. Its main structure is as follows: figure 1 As shown, the pot cover is provided with a pressure limiting valve 1a and an exhaust pipe 2a. The exhaust pipe 2a is arranged insid...

AI Technical Summary

Problems solved by technology

[0004] The pressure of the water vapor discharged by this exhaust device is relatively high, and the outlet speed is relatively fast, which will generate a lot of noise; and after multiple exhausts by using external force to lift the pressure limiting valve, the thimble of the pressure limiting valve may be damaged due to Air leakage caused by bumps, causing certain safety hazards
