Problems solved by technology

[0003] The inventor found that when the exhaust valve and the safety valve fail due to clogging and other reasons, the pressure in the cooking cavity continues to rise. When it reaches a certain pressure, for example, the pressure relief pressure of 200kpa, the inner cover will deform upwards to a certain extent. As a result, the sealing ring can be turned outwards to produce pressure relief, but because the pressure in the cooking cavity is very high when the pressure is released at this time, and the position of the sealing ring’s outward turning is random, resulting in the pressure release when the pressure is released outwards. The position is not fixed, and the pressure release position may be facing the user. At this time, a large amount of high-temperature steam is discharged, causing the user to be scalded by the high-temperature steam, which affects the safe use of the pressure cooker.

Abstract

The invention discloses an oriented decompression safety electric pressure cooker. The oriented decompression safety electric pressure cooker comprises a cooker body and a cooker cover; an inner container is arranged in the cooker body; the cooker cover comprises an inner cover which comprises a cover body, a sealing ring and a fixing ring; and the sealing ring is fixed to the cover body through the fixing ring and comprises a sealing lip for sealing the inner container. The oriented decompression safety electric pressure cooker is characterized in that the fixing ring is located on the outer side of the sealing lip; an allowing opening is formed in the position, close to the bottom face of the inner container, of the fixing ring; a peripheral stopping rib is arranged on the allowing opening upwards in the peripheral direction of the fixing ring; the sealing lip is extruded into the allowing opening through the pressure in the electric pressure cooker; in addition, the sealing lip at the position of the allowing opening is outwards turned to form a pressure relief opening; and the elastic deformation quantity of the cover body ranges from 2 mm to 5 mm when the sealing lip is outwards turned to form the pressure relief opening. In this way, the oriented decompression safety electric pressure cooker has the beneficial effects that safe decompression is considered, and the cost is low.

Description

technical field [0001] The invention relates to a kitchen cooking appliance, in particular to a safe electric pressure cooker with directional pressure relief. Background technique [0002] The current electric pressure cooker includes a pot cover and a pot body, an inner container is arranged in the pot body, an inner cover is arranged between the inner container and the pot cover, and a sealing ring is installed on the inner cover, and the sealing ring is used to realize the sealed connection between the inner container and the inner cover. The inner cover, the inner tank and the sealing ring form a cooking cavity, and the pot cover is also provided with safety devices such as an exhaust valve and a safety valve. [0003] The inventor found that when the exhaust valve and the safety valve fail due to clogging and other reasons, the pressure in the cooking cavity continues to rise. When it reaches a certain pressure, for example, the pressure relief pressure of 200kpa, the ...
