Heat shield for stove and stove using heat shield for stove

Abstract

The invention relates to a heat shield for a stove. The heat shield comprises an annular shield body. The heat shield is characterized in that the bottom of the shield body is provided with an annularliquid collecting tray extending in the horizontal direction of a center hole. Compared with the prior art, the heat shield has the advantages that on the basis of an existing gas stove, the heat shield for the stove is additionally arranged, a ring of annular liquid collecting tray for collecting overflowing liquid is additionally arranged at the bottom of the heat shield, and liquid can be effectively prevented from overflowing and entering a burner. Meanwhile, the heat shield is internally and fixedly provided with pot landing legs, the contact area between the pot landing legs and a pot can be increased, and therefore a flame can fully exchange heat with the bottom of the pot, heat absorbed by the pot landing legs can heat the bottom of the pot as much as possible through heat conduction, and the heat loss of the flame is reduced. The invention also discloses the stove using the heat shield, the liquid collecting tray of the shield body is matched with a base of the burner, liquidon the heat shield can finally flow into the liquid collecting tray, the pot landing legs, the liquid collecting tray and the heat-insulating performance are integrated, and the structure is ingenious and reliable.

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.
