Protective energy-saving cover for cooking pressure cooker

Abstract

The invention provides an energy-saving protective cover of a cooking pressure cooker. The energy-saving protective cover comprises a shell cover which is sleeved on a pressure cooker cover and provided with a heat insulating effect, wherein the shell cover comprises an outer shell and an inner sleeve which is sleeved with the outer shell; a sealed cavity is formed in the shell cover; a valve hole for avoiding a pressure limiting valve cap is formed in the shell cover; and a vapor discharging gap is formed between the valve hole and the circumferential side of the valve cap. A flow guide groove is formed on the internal side of the shell cover; and oil water in the valve hole can flow out via the flow guide groove. A heat insulating material can be filled in a cavity of the shell cover. An oil water cup and a cover cap are also arranged on the shell cover. The energy-saving protective cover provided by the invention can be used together with other heat insulating members arranged on the pressure cooker body, so that the energy-saving protective cover has more ideal protective, energy-saving and heat insulating effects, can bring convenience to cooking of the pressure cooker, is beneficial for saving energy and reducing emission and obtains promotion and application values.

Description

technical field [0001] The invention relates to a protective energy-saving cover for a cooking 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 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 ...

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.
