Protective energy-saving pressure cooker

Abstract

The protective energy-saving pressure cooker provided by the present invention includes a pot body and a matching pot cover. The pot cover is provided with a shell; the shell is an integral structure made of plastic materials; The valve hole has a steam exhaust 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; the lower end surface of each relief hole is tightly fitted to the pot cover On the outer surface, there is a suitable distance between the inner surface of the shell cover and the outer surface of the pot cover, and there is a closed cavity between the shell cover and the pot cover. The pot body of the pressure cooker of the present invention is also provided with a heat insulating cylinder and a cover pad, which has more ideal protection, energy saving and heat preservation performance as a whole, can bring more convenience to cooking and use, and is conducive to energy saving and emission reduction and has a popularization effect. 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.
