技术领域Technical field
本发明涉及厨房用具领域，更具体而言，涉及一种烹饪器具。This invention relates to the field of kitchen appliances and, more particularly, to a cooking appliance.
背景技术Background technique
现有的压力烹饪器具如电压力锅，因其具有烹饪快速、烹饪温度高、食物口感好以及节能等众多优点已成为我们厨房中必不可少的烹饪器具，现在困扰整个行业的问题是虽然电压力锅将食物很快烹饪好了，但是因为锅内高压，不能及时打开锅盖，这给用户带来很大不便。常规产品降压主要是通过自然热交换或者通过排气来降压。自然热交换需要时间很长，而在烹饪流体食物时如果通过排气降压会喷出食物，造成厨房污染，器具本身也难以清洗，用户还有可能被带出的流体食物或蒸汽烫伤。Existing pressure cooking appliances, such as electric pressure cookers, have become an indispensable cooking utensil in our kitchen because of their fast cooking, high cooking temperature, good food taste and energy saving. Now the problem that plagues the whole industry is that although the electric pressure cooker The food was cooked very quickly, but because of the high pressure in the pot, the lid could not be opened in time, which caused great inconvenience to the user. Conventional product bucks are primarily depressurized by natural heat exchange or by venting. Natural heat exchange takes a long time, and when cooking fluid food, if the food is sprayed out by the exhaust gas, the food is contaminated, the appliance itself is difficult to clean, and the user may be burnt by the fluid food or steam that is brought out.
为此众厂家开始研究如何快速、安全、干净的开盖，已有不少关于快速降压的方法产生，例如风冷、水冷等，经测试验证风冷的效果不是很理想；水的比热较大，冷却效果好。目前行业里有采用水循环盖板进行快速降压的方案，但是这种设计使得盖板不可拆，从而导致用户很难对盖板进行彻底清洗，影响用户的体验效果。For this reason, many manufacturers began to study how to open the cover quickly, safely and cleanly. There have been many methods for rapid depressurization, such as air cooling and water cooling. The test proved that the effect of air cooling is not ideal; the specific heat of water Larger, good cooling effect. At present, there is a scheme of adopting a water circulation cover for rapid pressure reduction in the industry, but this design makes the cover undetachable, which makes it difficult for the user to thoroughly clean the cover and affect the user experience.
发明内容Summary of the invention
