Lid assembly and cooking utensils

Abstract

The invention provides an upper cover component and a cooking utensil. The upper cover component comprises a cover lid, a steam valve cover, a thermal insulation plate and a steam valve base; the steam valve cover is installed on the cover lid; the steam valve cover is provided with a steam outlet; the thermal insulation plate is located under the cover lid and is connected to the cover lid; the thermal insulation plate is provided with an installing through hole; the steam valve base is provided with a steam inlet; the steam valve base is mounted at the installing through hole; the upper end of the steam valve base penetrates the installing through hole and is hermetically connected with the cover lid, so that the steam valve base and the cover lid define a closed steam channel; the lower end of the steam valve base is hermetically connected with the thermal insulation plate. The upper cover component has the advantages that the steam valve base can be stably installed; the structure of the upper cover component is more compact and the thickness of the product is reduced; steam is prevented for entering the upper cover component from installing gaps between the steam valve base and the cover lid and between the steam valve base and the thermal insulation plate, so that the problems that the product is corroded and the using safety and service life of the product are influenced because of accumulation of steam in the upper cover component are solved.

Problems solved by technology

[0002] At present, the lid of the existing electric rice cooker is equipped with at least five parts: a decorative sheet, an outer cover, an inner cover, a heat preservation seat plate and a movable cover plate from top to bottom, which complicates the composition of the lid and increases the cost accordingly. The overall thickness of the pot cover, and usually there is a sinking groove on the cover that runs through the upper and lower walls of the cover. A steam valve for exhausting steam is installed in the sinking tank. In order to ensure the firmness and stability of the steam valve installation, it is usually necessary to place the The surface cover is made thicker, which further increases the overall thickness of the lid; in addition, because there is an installation gap between the surface cover and the steam valve, this makes it easy for the water vapor generated by the rice cooker to pass through the surface cover and the steam valve. The installation gap between the valves enters the inside of the lid, causing water vapor to accumulate inside the lid, corroding the parts of the lid and the connection structure between the parts, thus affecting the service life of the product and affecting the cleanliness of the product
