Abstract

The invention provides a delayed switching valve of an electric pressure cooker. The delayed switching valve comprises a cooker cover steam outlet hole, and a floater and a sealing rubber ring which are used for sealing the steam outlet hole, wherein the floater is connected with a temperature control piece to form a linkage structure which moves along with the temperature control piece; after the temperature control piece has heated deformation, the floater is driven to move to a position for sealing the steam outlet hole; the steam outlet hole is formed in the upper part of a steam outlet cover; and the floater is located in the steam outlet cover and the steam outlet hole is sealed by the sealing rubber ring which is mounted at the upper part of the floater. According to the delayed switching valve of the electric pressure cooker, when rice is cooked by the electric pressure cooker to be boiling, the rice in the cooker is continuously boiled until the rice fully absorbs moisture, and then the cooker enters a pressure-keeping and rice-simmering state; the rice cooked by the process is soft and dry, is tough and chewy when being eaten and has an obvious rice flavor; and the rice in the cooker is continuously boiled until the rice fully absorbs moisture, and then the cooker enters the pressure-keeping and rice-simmering state no matter how much rice is cooked in the cooker; and the delayed switching valve has a reasonable structure and is applicable to large-batch production.

Description

A kind of delay cut-off valve of electric pressure cooker
Technical field
The present invention relates to relate to electric cooking appliance technical field, particularly relates to a kind of delay cut-off valve of electric pressure cooker.
Background technology
At present, electric pressure cooking saucepan on the market needs due to explosion prevention function, and its working procedure is all electrified regulation, and to the of short duration boiling of food, produce pressure, namely enter power-off packing state in pot, after pot inner pressure reduces, then electrified regulation is to power-off pressurize.Continuous circulation, until food boils, the process that boils like this, for the soup group food that the moisture content that boils is more, is not only facilitated but also power saving, and for boiling rice, effect is not just so good, if boil rice time, rice just seethes with excitement, electric pressure cooking saucepan just enters power-off packing state, and what now the grain of rice can only be static bubbles open in the hot water.Until electric pressure cooking saucepan again electrified regulation time, the rice in pot can not seethe with excitement again, and there is Rice & peanut milk on the rice rice grain surface cooked like this, and rice is not soft, moisture content is heavy, do not have a meter fragrance yet.
Summary of the invention
Object of the present invention is just to provide one and can be contained on existing electric pressure cooking saucepan product, can change the delay cut-off valve of electric pressure cooker of the rice process that boils.
Inventive solution is such:
A kind of delay cut-off valve of electric pressure cooker, comprise pot cover vapor opening and for the float that seals vapor opening and O-ring seal, described float and temperature control chip connect into the linkage structure of following temperature control chip and moving, and after temperature control chip produces temperature distortion, drive float movement to the position closing vapor opening; Described vapor opening is positioned at vapour cover top, and described float is positioned at vapour cover, sealed vapor opening by the O-ring seal being installed on buoy upper.
Further, the link gear that above-mentioned and described float is connected refers to that float and temperature control chip connect as one.
Advantage of the present invention is: adopt the present invention that electric pressure cooking saucepan can be made to boil rice to when seething with excitement, allow rice in pot boil to the grain of rice be continuously about to inhale full moisture content, then enter the vexed meal state of pressurize, through the soft solid carbon dioxide of rice rice grain that this process cooks, entrance has chewiness, and has obvious rice fragrance; No matter and can adapt to boil how much rice in pot, rice in pot can be allowed to boil to the grain of rice continuously and to be about to inhale full moisture content, then enter the vexed meal state of pressurize, rational in infrastructure, produce install simple, cost is low, is suitable for a large amount of production.
