Description

An air purifying range hood without an external unit air conditioner with hot water recovery

technical field

The invention belongs to the technical field of range hoods, and relates to a range hood, in particular to an air-purifying range hood without an external machine air conditioner with hot water recovery.

Background technique

At present, there are roughly the following types of household range hood products on the market: 1. According to the air purification method, it can be divided into three types: external exhaust type, circulating type and dual-use type.

The external exhaust type is to suck the oil fume gas in the room, and after the oil mist is separated, it is discharged to the outdoor through the pipeline. Because the cooking method in our country is mainly frying with fierce fire, there is a lot of oil smoke. In this case, the filter system of circulating and dual-purpose hoods is easy to pollute, difficult to clean and has poor smoke exhaust ability, which is not suitable for my country's national conditions. Therefore, our country Basically, they all produce exhaust hoods. The external exhaust range hood is installed on the upper part of the stove, and the motor in the body drives the impeller in the volute to rotate, forming a certain negative pressure in the area of the air inlet, and through the drainage of the smoke collecting cavity, it is within a certain space above the stove. A negative pressure area is formed, and the surrounding oil fume gas is attracted by the negative pressure to reach the filter screen. After filtering, a part of the large particle oil mist is separated, and the rest of the gas enters the centrifugal fan system inside the hood. After the high-speed rotation of the fan impeller, the oil fume gas is subjected to centrifugal force. The role of the impeller is thrown out of the impeller, and the oil fume is separated again. The separated oil flows into the oil cup through the oil guide system, and the purified fume is discharged out of the room along the air duct along the arc of the volute. After the indoor gas polluted by oil fume is separated by the oil fume of the range hood, the odor is greatly reduced, the air is purified, and the living quality of the user is improved; and the gas discharged outdoors, because the oil mist is separated, it will not be harmful to the environment. create pollution.

However, the existing equipment products still cannot meet the needs of users, such as energy saving and environmental protection, insufficient purification of oil fume, and high temperature of the operating environment.
