Protective energy-saving pressure cooker

Abstract

The protective and energy-saving pressure cooker provided by the present invention includes a pot body and a matching pot cover. The pot cover is also provided with a shell with a heat-insulating effect; the shell is made of a metal shell made of a metal sheet and made of a plastic material. The side cover is combined; the shell is provided with a valve position hole with a steam exhaust gap for avoiding the pressure limiting valve; the shell is provided with a relief groove for avoiding the cover handle on the pot cover and other safety valves. The relief holes of the components; the lower end surfaces of the relief holes are closely attached to the outer surface of the pot cover, and there is a suitable distance between the inner surface of the metal shell and the outer surface of the pot cover, and they together form a closed cavity. 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 convenience to cooking and use, and is beneficial to energy saving and emission reduction, so it has the value of popularization and application .

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 cover 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...

Problems solved by technology

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 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 outward heat dissipation, 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 and heat loss More, it is not conducive to energy saving when cooking, and it is not conducive to heat preservation after the pressure cooker stops cooking and heating
