Protective energy-saving pressure cooker

Abstract

The invention provides a protective energy-saving pressure cooker which comprises a cooker body (9) and a cooker cover (1) with a pressure-limiting valve and other safety components. The cooker cover (1) is provided with a housing (2) which is composed of a shell (3) and an inner bushing (4), and a closed cavity (20) is formed in the cooker cover (1); the housing (2) is provided with a handle receding groove (22), a valve position hole (21) and other receding hole grooves; the inner side of the housing (2) is provided with a flow guide groove (41); an oil water cup (5) is arranged at an outlet of the flow guide groove (41); the shell (3) is made of plastic; the inner bushing (4) is made of sheet metal; the cavity (20) is filled with cotton batting or cotton cloth; the shell (3) is provided with a housing cap (7) matched with the valve position hole (21); the outer side of the cooker body (9) is provided with heat insulation barrels (92), and the bottom of the pressure cooker is not covered; a sleeve gasket (94) which is connected with the heat insulation barrels (92) in a sealing mode is arranged under the lower portions of the heat insulation barrels (92). According to the protective energy-saving pressure cooker, the ideal safe protective action and the energy-saving heat preservation effect are achieved, safe usage of the pressure cooker is not influenced, use is convenient, energy conservation and emission reduction are facilitated, and the application and popularization value is achieved.

Description

[0001] This application is a divisional application with an application date of August 1, 2011, an application number of 2011102162581, and an invention title of a protective energy-saving pressure cooker. technical field [0002] The invention relates to a protective energy-saving 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 by the handle of the pot cover, most of...

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.
