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 composed of shells 3 and side encircling sleeves 4; the side encircling sleeves 4 are closely matched with the shells 3 and sealed to a cooker cover 1; each shell 3 is provided with a clearance groove 22, a valve position hole 21 and other clearance hole grooves; 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; an interval is set between the lower end face of each valve position hole 21 and the surface of the cooker cover 1; the lower end portion of each valve position hole 21 is provided with an annular sleeving groove 31 and a rubber ring 32; an overflow port 33 is formed in the lower end of each rubber ring 32; each side encircling sleeve 4 is provided with a flow discharge port 41 and a flow guiding groove 42; each shell 3 is provided with a hood cap 8; 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...

AI Technical Summary

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 cooker is used, the temperature of the high-temperature pressure cooker The lid of the pot is always in a state of radiating heat outward, and because of its high surface temperature, large exposed area, and a lot of heat loss, especially in winter when the ambient temperature is low, the temperature difference between the lid and the surrounding environment is large, and the heat dissipation is faster and the loss The heat is more, which is not conducive to energy saving when cooking, and is also not conducive to the heat preservation of the pressure cooker after stopping cooking and heating.
