Protective energy-saving cover of pressure cooker

Abstract

The invention provides a protective energy-saving cover of a pressure cooker. The protective energy-saving cover comprises a cooker cover body 1 provided with a cover handle 13, a pressure limiting valve and other safety components, and a shell housing 2 composed of an outer shell 3 and an inner sleeve 4 and provided with a closed cavity 20 is arranged on the cooker cover body 1. The shell housing 2 is provided with a valve position hole 21, a handle receding groove 22 and other receding hole grooves. A flow guide groove 41 is formed in the inner side of the shell housing 2. Finely-divided adiabatic dried materials are arranged in the cavity 20. A cover cap 7 matched with the valve position hole 21 is arranged on the outer shell 3. The protective energy-saving cover has the safety protective effect and energy saving and heat insulation effects, does not affect safe usage of the pressure cooker, and is convenient to use and beneficial to energy saving and emission reduction, thereby having the application and popularization value.

Description

[0001] This application is a divisional application with an application date of August 1, 2011, an application number of 2011102162596, and an invention name of a protective energy-saving cover for a cooking pressure cooker. technical field [0002] The invention relates to a protective energy-saving cover for a cooking pressure cooker. Background technique [0003] 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 ...

AI Technical Summary

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.
