Heat-insulating cover for stove and stove applying heat-insulating cover for stove

Abstract

The invention relates to a heat-insulating cover for a stove. The heat-insulating cover comprises an annular cover body, and is characterized in that the cover body is of a double-layer structure composed of an upper-layer cover and a lower-layer cover, a hollow cavity is formed between the upper-layer cover and the lower-layer cover, a separating piece is further arranged in the hollow cavity, and the edge of the periphery of the separating piece abuts against the inner wall of the hollow cavity so as to divide the hollow cavity into at least two sub-hollow cavities. Compared with the prior art, the heat-insulating cover for the stove has the advantages that the heat-insulating cover for the stove is additionally arranged on the basis of an existing gas stove, the heat-insulating cover isof the double-layer structure and is provided with the hollow cavity, the separating piece is further arranged in the hollow cavity, so that the hollow cavity of the heat-insulating cover is dividedinto the plurality of sub-hollow cavities with relatively independent closed spaces so as to effectively reduce convection heat exchange of air in the hollow cavity and further reduce convection heatexchange of air in the hollow cavity and air outside the hollow cavity, the invention further discloses the stove applying the heat-insulating cover, secondary air supplementing grooves of the cover body can be arranged aligned with secondary air inlets of a gas mixing chamber of a combustor one by one so that secondary air can be effectively supplemented.

Description

technical field [0001] The invention relates to a heat shield for a cooker, and also relates to a cooker using the heat shield for a cooker. Background technique [0002] With the development of the city gas industry, my country's stove industry has greatly improved in terms of variety, material, performance, and sales. A very important point in its performance improvement is the improvement of thermal efficiency. The burners of household gas stoves are mostly atmospheric burners. The atmospheric burner is a burner designed according to the partial premixing method, and its primary air coefficient is 0<α<1. The atmospheric burner is divided into two parts: the head and the ejector. The ejector is used to eject the primary air required for combustion, and the function of the burner head is to evenly distribute the mixture of gas and air to the fire hole for stable and complete combustion. The gas of the gas stove is mainly liquefied petroleum gas, natural gas, bioga...

AI Technical Summary

Problems solved by technology

In the actual use of existing gas stoves, since the pot is placed on the pot support for heating, there is a certain space between the pot and the burner. A part escapes into the surrounding environment, causing energy waste; in order to solve the above problems, some heat collection and energy gathering have occurred in China in recent years, such as the "energy gathering ring for gas stoves and gas stoves with it" disclosed in Chinese patent CN203404823U ", and as disclosed in Chinese patent CN204042984U "a kind of energy-gathering gas cooker", the cooker also has an energy-gathering pan support, although the above-mentioned energy-gathering ring structure can reduce the consumption of heat energy to a certain extent, but Gas stoves are generally placed in the ventilated place of the kitchen. When the wind in the external environment is strong, the combustion flame of the gas stove may swing, become unstable, and sometimes even cause flameout, affecting use

In addition, existing ordinary gas stoves still have slippery pots, and cooking soup overflows into the burner burner, fire holes, etc., causing gas stoves to extinguish and fail to ignite.
