Protective energy-saving pressure cooker

Abstract

The invention provides a protective and energy-saving pressure cooker which comprises a cooker body and a cooker cover matched with the cooker body, and a casing cover is arranged on the cooker cover. The casing cover is formed by a housing and a lateral encircling sleeve, and the housing and the lateral encircling sleeve are made of a plastic material. A valve position hole for avoiding a pressure-limiting valve is arranged on the casing cover, a steam exhausting gap is arranged on the casing cover, and a receding groove for avoiding a cover handle and receding hole grooves for avoiding other safety components. The lower end faces of the receding hole grooves are sealed on the outer surface of the cooker cover, an appropriate gap is reserved between the inner surface of the casing cover and the outer surface of the cooker cover, and a sealed cavity is arranged between the casing cover and the cooker cover. A heat insulation tube and a sleeve cushion are further arranged on the cooker body of the protective and energy-saving pressure cooker. The protective and energy-saving pressure cooker integrally has ideal protective, energy-saving and heat insulation performance, can bring more convenience to cooking in use, facilitates energy conservation and emission reduction, and has popularization and application value.

Description

technical field [0001] The invention relates to a pressure cooker, in particular to a protective and energy-saving 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 te...

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.
