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.

Abstract

The invention provides a protective energy-saving cover for high-pressure cookers. The protective energy-saving cover for high-pressure cookers comprises a thermal insulation cover 2 which is made of thermal insulation material and covers a high-pressure cooker cover 1. The thermal insulation cover 2 is provided with a valve hole 21, and a steam exhaust gap is reserved between the valve hole 2 and a bonnet 11. A guide channel 24 allowing greasy water in the valve hole 21 to flow out is arranged on the inner side of the thermal insulation cover 2. The thermal insulation cover 2 is further provided with a greasy water cup 3, a cap 5 and a shell film 4 or cover shell 6. The protective energy-saving cover can be used with other thermal insulating members disposed on the high-pressure cooker to achieve better protection, energy conservation and thermal insulation. Therefore, using the high-pressure cooker to cook can be facilitated. The protective energy-saving cover contributes to energy conservation and emission reduction and is worthy of popularization and application.

Description

[0001] This application is a divisional application whose application number is 2011102071493, the application date is July 25, 2011, and the invention name is a protective energy-saving cover for 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 by ...
