Steam valves, lid assemblies and cooking utensils

Abstract

The invention provides a steam valve, an upper cover assembly and a cooking utensil. Wherein, the steam valve has an upper chamber and a lower chamber, a heat exchange layer is formed between the upper chamber and the lower chamber, the lower chamber forms a steam chamber for communicating with the steam in the pot, and the upper chamber forms a steam chamber for communicating with the outside world. Connected airflow channels. In the steam valve provided by the present invention, when the air bubbles in the lower chamber reach the heat exchange layer, heat exchange occurs with the natural convection air in the upper chamber, so that the air bubbles in the lower chamber cool down rapidly and automatically when they reach the heat exchange layer. shattered to achieve the effect of breaking bubbles; secondly, when the steam enters the lower cavity and flows in the lower cavity, it will gradually condense and flow back to achieve the effect of breaking bubbles, so as to strengthen the heat dissipation structure and set up related bubble breaking structures It achieves double foam-breaking effect and realizes the anti-overflow effect of small-volume steam valve and large-volume 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...

AI Technical Summary

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
