Steam valve, upper cover assembly and cooking utensil

Abstract

The invention provides a steam valve, an upper cover assembly and a cooking utensil. The steam valve is at least provided with a heat exchange layer made of a heat conduction material, a condensation surface used for being in contact with steam in a pot is formed on the surface of one side of the heat exchange layer, and a heat dissipation surface used for being in contact with outside air is formed on the surface of the other side of the heat exchange layer. The invention provides the steam valve, in which good thermal conductivity of the heat exchange layer is utilized to guide heat energy of water vapor and rice soup foam generated in the pot out of the pot, so water vapor, rice soup foam and the like can be cooled and condensed on the condensation surface of the heat exchange layer and condensed into liquid to flow back into the pot, and then the rice soup foam is automatically broken. That is to say, the foam breaking efficiency of the steam valve is improved and the effective anti-overflow effect is achieved by enhancing the heat dissipation and cooling effect of the steam valve.

Description

technical field [0001] The invention relates to the field of kitchen utensils, more specifically, to a steam valve, an upper cover assembly and a cooking utensil. Background technique [0002] Overflow pot is a problem that has always existed in the rice cooker industry. To make the rice plump and delicious, it needs to be boiled enough to absorb the water. However, once the fire boils, the water vapor will be continuously generated. Excessive water vapor will accumulate in the pot and bring pressure. In order to reduce the pressure, the water vapor must be released. , At this time, the rice soup is prone to overflow. The higher-end rice cookers in the industry all have steam valves to improve the overflow problem. [0003] At present, rice cookers with better anti-overflow effects in the industry basically adopt this idea: the steam valve cavity has a large space, and the space is exchanged for the steam condensation and reflow time, so that it can realize cooling and ref...

Problems solved by technology

These solutions have made a great contribution to improving the performance of the rice cooker, but the large steam valve also has certain limitations, mainly as follows: 1) the integrity of the appearance is sacrificed; 2) the upper cover is thick; 3) the cleaning of the steam valve is slightly significantly complicated
