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.

Embodiment 1

[0023] The protective and energy-saving cover of the cooking pressure cooker in the first embodiment of the present invention (see Figure 1-Figure 7 ), including a lid 1 with a lid handle 13, the lid 1 is equipped with a pressure limiting valve with a valve cap 11 and a safety valve 14; the lid 1 is provided with a shell 2 for covering its outer surface; the shell 2 consists of The outer shell 3 and the inner sleeve 4 nested therewith are formed with an appropriate distance between the inner side walls of the two and form a closed cavity 20; the shell cover 2 is provided with a valve position hole 21 for avoiding the bonnet 11, There is a suitable exhaust gap between the valve position hole 21 and the peripheral side of the bonnet 11, so that the vapor ejected from the bonnet 11 can be discharged from the gap; the housing 2 is provided with a relief cover handle 13 Handle slot 22.

[0024] The housing 2 is provided with a safety hole 23 for avoiding the safety valve 14 so that t...

Embodiment 2

[0045] The protective energy-saving cover of the cooking pressure cooker in the second embodiment of the present invention (see Figure 8-9 ). In order to make the function of the protective energy-saving cover of the present invention more perfect, and make it easier to implement and apply, on the basis of the first embodiment of the present invention, the second embodiment of the present invention is further configured as follows, namely: the above-mentioned shell 2 The cavity 20 is provided with an interlayer 6 made of foamed plastic material with heat insulation effect; the interlayer 6 and the mating surface of the inner sleeve 4 are attached to each other, so that the two are closely adhered or bonded together.

[0046] The constructed interlayer 6 has a good thermal insulation effect, which is beneficial to enhance the thermal insulation performance of the shell cover 2 in this embodiment, so that the protective and energy-saving cover of the cooking pressure cooker of thi...

Abstract

The invention provides a protecting energy-saving cover for a pressure cooker. The protecting energy-saving cover comprises a pot cover body (1) which is provided with a cover handle (13), a pressure limiting valve and other safety members. The pot cover body (1) is provided with a housing (2) which is formed by a shell (3) and an inner sleeve (4) and provided with a closed cavity (20). The housing (2) is provided with a valve position hole (21), a handle receding groove (22) and other receding hole grooves. The shell (3) is made of plastic, and the inner sleeve (4) is made of sheet metal. A ring sleeve groove (31) and a rubber ring (32) are arranged under the valve position hole (21). Cotton fiber or strip-shaped cotton cloth is arranged in the cavity (20). The protecting energy-saving cover has a safety protection function and energy-saving and heat-preserving effects without influencing safety use of the pressure cooker, is convenient to use and beneficial for energy conservation and emission reduction, and has 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 ...
