Protective energy-saving cover for cooking pressure cooker

Abstract

The protective energy-saving cover for cooking pressure cooker provided by the present invention comprises a shell cover set on the cover of the pressure cooker; the shell cover is an integral structure made of non-metallic material; The valve position hole of the gap; the cover is provided with a relief groove for avoiding the handle of the cover and a relief hole groove for avoiding other safety components; There is a suitable distance between the inner surface of the shell and the outer surface of the fitted pot cover, and a closed cavity is formed between the shell cover and the pot cover. The protective energy-saving cover of the present invention can be customized and matched according to the structural characteristics of the pressure cooker lid, and can be matched with other heat-insulating components arranged on the pressure cooker. It has more ideal protection, energy-saving and heat preservation effects, and can bring convenience to the cooking and use of the pressure cooker. And it is conducive to energy saving and emission reduction and has the value of popularization and application.

Description

technical field [0001] The invention relates to a protective energy-saving cover for a cooking pressure cooker. Background technique [0002] 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 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 ...

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.
