Range hood with oil smoke internal circulation filtration function

Abstract

The invention discloses a range hood with an oil smoke internal circulation filtration function. The range hood comprises a rear cover, an air suction seat arranged in the rear cover, and an air blower arranged in the air suction seat and used for generating an oil smoke adsorption effect, wherein a filtering device which communicates with an air outlet of the air blower and is used for filteringoil smoke is further arranged in the rear cover, and an internal circulation machine seat which is connected with the air outlet end of the filtering device in a sealing mode so as to realize circulation flow of filtered gas is further arranged in the rear cover. The range hood with the oil smoke internal circulation filtration function has the advantages that the structure is simple, use is simple, the effects of being safe and convenient are achieved, cleaning is avoided, the effect of being not prone to blockage is achieved, the oil smoke filtering effect is good, the discharged gas after filtration is free of peculiar smell, the environment is protected, the trouble of dismounting and washing of the range hood is reduced, and the cost is reduced, so that the service life of the range hood is prolonged, the oil smoke gas can be thoroughly purified, kitchen waste heat is effectively absorbed, the indoor environment temperature of a kitchen is reduced, and the living requirements of different families are greatly met.

Description

technical field [0001] The invention relates to the technical field of range hoods, in particular to a range hood which adopts a filter device to filter oil fumes and discharges them indoors through an internal circulation flow instead of a traditional channel to discharge them outdoors. Background technique [0002] Along with the continuous growth of my country's economy and the continuous improvement and enhancement of national living standards, kitchen range hoods have become a necessity for people's lives. However, due to the short development time of range hoods in my country, the products in the existing market mainly focus on exhausting smoke, and there is little consideration for energy conservation and environmental protection. The exhausting smoke from people's daily cooking causes serious pollution to the outdoor and indoor environments; Domestic range hoods are all external exhaust, which directly discharges the oil fume into the atmosphere, causing secondary pol...

Problems solved by technology

However, due to the short development time of range hoods in my country, the products in the existing market mainly focus on exhausting smoke, and there is little consideration for energy conservation and environmental protection. The exhausting smoke from people's daily cooking causes serious pollution to the outdoor and indoor environments; The domestic range hoods are all of the external exhaust type, which directly discharges the oil fume into the atmosphere, and there is secondary pollution of the oil fume, while the technology of the internal exhaust range hood is extremely rare in the market

[0003] Therefore, in view of the shortcomings of the external exhaust range hood, some internal exhaust range hoods have gradually appeared in recent years. Most of this type of internal exhaust range hood adopts the method of separating the oil fume and then discharging it into the kitchen to realize the indoor operation. Circulation, this kind of oil fume separation technology mostly uses activated carbon, centrifugal separation and other purification treatment, but the structure of this kind of purification treatment device is relatively complicated, the cost is too high, the service life is short, and it needs to be replaced frequently, etc.

[0004] In addition, since the effective utilization rate of the combustion heat of gas stoves in the existing market is mostly between 40 and 50%, the remaining heat, that is, waste heat, is dissipated in the kitchen space, which cannot effectively absorb or discharge waste heat, which will greatly increase the indoor temperature. Reduce the use effect of other household appliances in the room

The purification device of this type of internal exhaust range hood on the market only has the function of simply separating the oil fume, does not have the function of heat absorption and cooling, and cannot effectively discharge or cool the waste heat in the kitchen space; moreover, it is confused with the oil fume The grease in the air not only pollutes the fan and air duct, but also hinders the purification of harmful gases by the purification material.
