Protective energy-saving hood of pressure cooker

Abstract

The invention provides a protective energy-saving hood of a pressure cooker.The protective energy-saving hood of the pressure cooker comprises a housing 2 arranged on a cooker cover 1 in a sleeving mode and composed of shells 3 and side encircling sleeves 4; the shells 3 and the side encircling sleeves 4 are both made from plastic cement; the side encircling sleeves 4 are closely matched with the shells 3 and sealed to the cooker cover 1; each shell 3 is provided with a clearance groove 22, a valve position hole 21 and other clearance hole grooves, and the lower end faces of the clearance hole grooves are sealed to the surface of the cooker cover 1; a closed cavity 23 is defined by the housing 2 and the cooker cover 1; the peripheral edge of the upper end of each valve position hole 21 is not higher than the lower edge of a cap hole 12; the inner side wall of each shell 3 is provided with a liner 5 made from foaming plastic cement.The protective energy-saving hood is used on the pressure cooker cover in a matched mode and has the safety protection effect and the energy-saving and heat-preserving effects, cooking of the pressure cooker can be made convenient, and the protective energy-saving hood facilitates energy conservation and emission reduction, so that the protective energy-saving hood has application and popularization value.

Description

[0001] This application is a divisional application whose application number is 201110258670X, the application date is September 5, 2011, and the invention name is a protective energy-saving cover for cooking pressure cooker. technical field [0002] The invention relates to a protective energy-saving cover for a cooking pressure cooker. Background technique [0003] Most of the cooking pressure cookers used by the public on gas stoves or induction cookers (hereinafter referred to as: pressure cookers or ordinary pressure cookers) are mostly made of aluminum alloy or stainless steel, which brings many conveniences to people's lives. Compared with automatic electric pressure cookers, ordinary pressure cookers In the cooking process, the firepower can be adjusted at any time at will, which has certain advantages in use. However, the metal surface of ordinary pressure cooker has a large exposed area, especially the pot lid of the pressure cooker. Except for a small part covered...

Problems solved by technology

However, the metal surface of ordinary pressure cooker has a large exposed area, especially the pot lid of the pressure cooker. Except for a small part covered by the handle of the pot cover, most of the metal surface is exposed. During the cooking process, the exposed pot cover surface is at a relatively high temperature. state, and because of its high surface temperature, when the human body accidentally touches it, it is easy to be scalded or scalded; the more obvious disadvantage is that in the process of cooking in a pressure cooker, no matter whether a gas stove or an induction cooke
