Constant temperature pot containing vacuum cavity on bottom of pot body

Abstract

The invention relates to a constant temperature pot containing vacuum cavity on the bottom of a pot body. The pot includes a pot body bottom wall, a first pot body side wall and a second pot body sidewall connected to the upper end of the first pot body side wall; the first pot body side wall is internally provided with a vacuum cavity communicated with a vacuum cavity in the pot body bottom wall, the vacuum cavity in the pot body bottom wall is internally provided with a liquid phase change working medium, and the vacuum cavity of the first pot body side wall is internally provided with a liquid sucking core. Since the liquid sucking core is arranged in the vacuum cavity of the first pot body side wall, after the liquid working medium in the vacuum cavity in the pot body bottom wall is heated, the liquid working medium is volatilized into gas, and the gas spreads to the top of the vacuum cavity of the first pot body side wall; then, the cooled working medium is condensed and converted into a liquid, the liquid flows along a heat conducting cavity into the vacuum cavity in the bottom of the pot body to be heated and volatilized again, and by repeating the procedures above, it is ensured that temperature fields at different positions on the inner sides of the whole pot body bottom wall and the first pot body side wall are basically maintained uniform, and the heating efficiencycan be improved.

Description

technical field [0001] The invention relates to a uniform temperature pot with a vacuum cavity at the bottom of the pot, which belongs to the field of uniform heat pots. Background technique [0002] At present, the material of the inner tank of electric rice cooker or pressure cooker is generally aluminum alloy or aluminum alloy / stainless steel composite plate. They mainly realize the non-stick coating such as PTFE (Teflon) on the surface of the inner layer of aluminum to realize the surface in the cooking process. non-stick effect. However, these non-stick coatings have poor wear resistance and are relatively easy to fall off. After being absorbed by the human body, they may cause safety hazards to consumers' health. Therefore, companies such as Datong Electric Appliances in Taiwan and Runtang Electric Appliances in Shenzhen have developed healthy uncoated inner pots heated by electric heating plates, and achieve a certain physical non-stick effect by controlling the temp...

Problems solved by technology

[0003] The technical problem to be solved by the present invention is to provide a uniform temperature cooker with a vacuum chamber at the bottom of the cooker, which overcomes the potential safety hazard caused by adding a non-stick coating to prevent uneven heating temperature distribution in the prior art and prevents the heat from sticking to the cooker. flaws exploited
