Environment-friendly energy-saving hood of gas stove

Abstract

The invention discloses an environment-friendly energy-saving hood of a gas stove, relates to a part of a household gas stove, and aims to solve the problem that the combustion products such as hot smoke and flame of the conventional gas stove are exposed to the air, so that the heat is not fully utilized and the environment is polluted. The environment-friendly energy-saving hood of the gas stove comprises an air distributor and a re-radiation shield, wherein the air distributor is an annular assembly which is placed around a fire plate of the gas stove; the annular assembly comprises an annular ring and an annular baffle; vent holes are formed in the annular ring in the circumferential direction and the annular ring is sleeved with the annular baffle plate so as to provide a proper amount of secondary air for combustion; the re-radiation shield is a heat transfer unit which is assembled at the upper part of the air distributor, and is a three-layer structural body, the inner layer is a radiation coating, the middle layer is a thermal insulation layer and the outer layer is a stainless steel shell; the air distributor is connected with the re-radiation shield through an annular bracket at the lower part of the re-radiation shield in an embedding manner so as to support the re-radiation shield. The environment-friendly energy-saving hood is capable of improving the heat efficiency of the gas stove and reducing the emission of the carbon monoxide and the carbon black, reasonable and simple in structure and convenient to use.

Description

Technical field [0001] The invention relates to a household gas stove accessory, in particular to an environmental protection and energy-saving cover installed on a gas stove to reduce flame heat dissipation loss and pollutant discharge. Background technique [0002] Gas stoves are combustion devices that use gas fuels such as natural gas and liquefied petroleum gas, and have become very popular household kitchen appliances. At present, there are many types of household gas stoves, novel styles, and good safety measures, materials, and functions. But the working principle is similar, that is, when the existing gas stoves are burning, they mostly use direct heating, and the hot smoke (flame) of the combustion product is exposed in the air, which causes the flame to heat the pot and the large amount of heat is not fully utilized. And lost to the surrounding air. At the same time, excessive air is mixed into the flame prematurely, lowering the flame temperature, making the combust...
