Protective energy-saving cover for cooking pressure cooker

Abstract

The invention provides a protective energy saving cover of a cooking pressure cooker. The protective energy saving cover of the cooking pressure cooker comprises a cover which is arranged on a pot cover of the pressure cover in a sleeved mode, wherein the cover has a heat insulation function. The cover is composed of an outer shell and a side surrounding cover. The outer shell and the side surrounding cover are both made of plastic materials. A valve location hole which is provided with gas exhaust gaps is formed in the cover, wherein the valve location hole is used for avoiding a pressure limiting valve. A receding groove which is used for avoiding a pot cover handle and receding holes and receding grooves which are used for avoiding other safe components are formed in the cover. Lower end faces of various receding holes and receding grooves are tightly attached to an outer surface of the pot cover. An appropriate interval exists between an inner surface of the outer shell and the sleeved outer surface of the pot cover. A sealing cavity is formed between the cover and the pot cover. The protective energy saving cover of the cooking pressure cooker can be customized and matched based on structure features of the pot cover of the pressure cooker and used with other heat insulation organizations arranged on the pressure cooker in a matched mode and therefore the protective energy saving cover of a cooking pressure cooker has the advantages of being ideal in protective effect, energy-saving effect and heat preservation effect, providing convenience for cooking use of the pressure cooker and benefiting energy conservation and emission reduction, thereby having popularization and utilization value.

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.
