Description

Environmentally friendly and energy-saving cover for a gas stove

technical field

The invention relates to a household gas stove accessory, in particular to an environmental protection and energy-saving cover installed on the gas stove to reduce flame heat dissipation loss and pollutant discharge.

Background technique

Gas stoves are combustion devices that use gaseous fuels such as natural gas and liquefied petroleum gas, and have become a highly popular household kitchen utensil. At present, there are many varieties 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 stove burns, it mostly uses direct heating, and the hot smoke (flame) of the combustion product is exposed in the air, causing the flame to heat the pot while a large amount of heat is not fully utilized. and dissipated into the surrounding air. At the same time, excessive air is mixed into the flame prematurely, which reduces the flame temperature, makes the combustion insufficient, and the concentration of carbon monoxide and carbon black in the flue gas is relatively high. The dissipated heat raises the temperature of the kitchen, and the emitted carbon monoxide and carbon black pollute the indoor environment. Therefore, improving the heat transfer performance of gas stoves and reducing pollutant emissions is an urgent problem to be solved, which has very important economic and social value for China with a population of 1.3 billion.

Contents of the invention

In order to solve the problem that the hot flue gas and flame of the combustion products of the existing gas stove are exposed in the air, the heat is not fully utilized and the environment is polluted, the present invention further provides an environmental protection and energy-saving cover for the gas stove, which can improve the thermal efficiency of the gas stove, Reduce carbon monoxide and carbon black emissions, and the structure is reasonable and simple, easy to use.

The technical scheme that the present invention takes in order to solve the problems of the technologies described above is:

An environment-friendly and energy-saving cover for a gas stove according to the present invention includes an air distribution device and a reradiation cover. Ventilation holes, the ring ring is covered with a ring baffle to provide an appropriate amount of secondary air for combustion; the re-radiation cover is a heat transfer device assembled on the upper part of the air distributor, which is a three-layer structure, the inner layer is radiant coating, the middle layer It is a heat insulation layer, and the outer layer is a stainless steel cladding. The air distributor is embedded and connected with the ring bracket provided at the lower part of the re-radiation cover to support the re-radiation cover. The two are easy to assemble.

Preferably: the radiation coating is an infrared radiation coating. Such setting has a higher emissivity and plays a role in enhancing heat transfer.

Preferably: the heat insulation layer is a ceramic heat insulation layer. With this setting, the heat insulation effect is good, and the heat loss can be better prevented. The ceramic heat insulation layer can withstand high temperature and can protect the stainless steel cladding from being burned by flames.

Preferably: the interior of the stainless steel cladding is a vacuum chamber. Such setting has a good heat preservation effect and can significantly reduce heat dissipation loss.

The principle of the environmental protection and energy-saving cover of the present invention is that the outer side of the flame heats the reradiation cover to make it rise to a higher temperature, and the infrared radiation layer inside the high-temperature re-radiation cover generates efficient infrared radiation to reheat the pot body; The device controls the amount of air entering the flame and increases the temperature of the flame, which will enhance the combustion and heat transfer between the flame and the pot. The two work together to improve the thermal efficiency of the gas stove and achieve the purpose of energy saving and environmental protection.

Compared with the prior art, the present invention has the following effects:

The gas stove is a kind of combustion equipment, and the pot is a kind of heat transfer equipment. Only when the two cooperate well can the utilization rate of fuel be high. However, there is no enclosure around the fire plate of the traditional gas stove, and the high-temperature flame radiates heat to the surroundings in a large amount by radiation and convection, and a large amount of excess air is mixed into the flame, resulting in a decrease in the temperature of the flame, which in turn reduces the heat absorption of the pot. Small, the thermal efficiency is reduced. The environmental protection and energy-saving cover provided by the present invention can just solve these two problems. First of all, the reradiation cover has both good heat preservation and radiation capabilities, which can gather the heat that was originally lost to the surroundings and then radiate it to the pot; secondly, the ventilation holes on the air distribution device can provide an appropriate amount of air for combustion, which can Ensuring full combustion can increase the flame temperature, which will enhance the heat transfer between the flame and the pot. Therefore, the use of the environmental protection and energy-saving cover involved in the application of the present invention can increase the flame temperature without losing heat, and can greatly improve the utilization rate of gas.
