Protective and energy-saving cover for pressure cooker

Abstract

The invention provides a protective and energy-saving cover for a pressure cooker. The protective and energy-saving cover comprises a shield 2 arranged on a pot cover 1 in a sleeving mode, wherein the shield 2 is composed of a metal shell 3 made of sheet metal and a side surrounding sleeve 4 made of plastic, a valve location hole 21, a receding groove 22 and receding hole grooves used for avoiding other safety components on the pot cover 1 are formed in the shield 2, and the shield 2 and the pot cover 1 are matched to define a cavity 23. The protective and energy-saving cover has a safety protection function and an energy-saving and heat-insulating effect, safe use of the pressure cooker is not affected, using is convenient, energy saving and emission reduction are facilitated, and application and popularization value is high.

Description

[0001] This application is a divisional application with an application date of September 2, 2011, an application number of 2011102568684, and an invention name of a protective energy-saving cover for a 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 cover of the pressure cooker. Except for a small part cov...

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 in 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 during the cooking process of the pressure cooker, no matter whether the gas stove or the induction cooker is used, the pot of the high-temperature pressure cooker The cover 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 pot cover and the surrounding environment is large, and the heat dissipation is faster. The heat is more, which is not conducive to energy saving during cooking, and is also not conducive to the heat preservation of the pressure cooker after stopping cooking and heating
