Upper cover assembly and cooking appliance adopting upper cover assembly

Abstract

The invention discloses an upper cover assembly and a cooking appliance adopting the upper cover assembly. The upper cover assembly comprises a steam valve assembly arranged in the upper cover assembly and a drive assembly matched with the steam valve assembly for use and further comprises a heating assembly, wherein the drive assembly drives the steam valve assembly to exhaust air when the temperature of the heating assembly exceeds the environment temperature. The heating assembly and the drive assembly are matched for use, the steam valve assembly can flexibly perform air exhausting, the structure is simple, and the user experience is improved.

Description

technical field [0001] The invention relates to the field of kitchen appliances, in particular to an upper cover assembly and a cooking utensil therefor. Background technique [0002] Cooking appliances will generate a large amount of water vapor during the cooking process. In order to guide and discharge the water vapor to the outside of the cooking appliance, a steam valve is generally arranged on the upper cover of the cooking appliance. steam channel. At present, the steam channel is set to be normally open. However, in the working stages of cooking utensils such as stewing rice and keeping warm that do not need to discharge water steam, because the opening of the steam channel will cause the heat inside the cooking appliance to be dissipated from the steam channel, it will not only affect Stewing rice and heat preservation effect, but also cause unnecessary energy loss.

AI Technical Summary

Problems solved by technology

At present, the steam channel is set to be normally open. However, in the working stages of cooking utensils such as stewing rice and keeping warm that do not need to discharge water steam, because the opening of the steam channel will cause the heat inside the cooking appliance to be dissipated from the steam channel, it will not only affect Stew rice and heat preservation effect, but also cause unnecessary energy loss

[0003] A foreign company has applied for a heat preservation pot, which has a cover body, a steam port is provided on the cover body, and a steam channel for exhaust is provided inside the steam port; a valve body is provided in the steam channel, and the valve body The valve body can change the size of the steam channel with the change of temperature. The valve body is made of elastic material with shape memory function. The elastic material can memorize the shape of the steam passing between the lines. The gap between the extension lines of the valve body becomes wider when the temperature is higher than the set temperature, and the gap between the compression lines of the valve body becomes narrower when the temperature is lower than the set temperature. However, if the steam channel is blocked, it will not be able to act accurately at the first time

[0004] In addition, a domestic company discloses a steam valve and cooking utensils to solve the above problems. Specifically, the drive unit senses the temperature or humidity of the steam to drive the exhaust cover to move relative to the valve body, and the drive unit is arranged on the steam outlet of the exhaust seat. After the steam in the steam channel passes through the steam hole, it can immediately contact the drive unit, thereby improving the accuracy of the automatic control of the steam valve, and further improving the comfort and safety of the product. However, this patent will One problem is that, due to the large amount of foam generated during the cooking process, after the foam enters the steam valve, other media that the foam may carry will block the steam valve, thus affecting the accuracy of the drive unit to sense the steam temperature
