Double-side filter air input purifier with filter nets of large wind area

Abstract

The invention discloses a double-side filter air input purifier with filter nets of large wind area. The double-side filter air input purifier comprises a motor wind wheel, air channels, a front machine case, a rear machine case and a top cover. The front machine case and the rear machine case are spliced to form space for arranging the motor wind wheel and the air channels, and the top cover is fixedly arranged on the front machine case and the rear machine case and located above air outlets of the air channels. Air can enter the front side and the rear side of the double-side filter air input purifier, the front machine case and the rear machine case are respectively provided with a main air inlet and an auxiliary air inlet, the air channels comprise a main air channel and an auxiliary air channel, the auxiliary air channel is communicated with the auxiliary air inlet, and the air channels have the advantages of being large in air input amount and air purifying amount. The filter nets arranged on a front machine case body and a rear machine case body have large wind area, the utilization rate is high, the filter nets arranged on the front machine case body and the rear machine case body can have the same function or different functions, and the humidifying function and electrostatic precipitation function can be achieved at the same time when a humidifying impeller and an electrostatic precipitation net are respectively arranged.

Description

technical field [0001] The invention relates to the technical field of air purification, in particular to an air purification device. Background technique [0002] The air inlet of the air cleaner currently on the market is set on one side, and the centrifugal wind wheel is opened on one side. The size of the air inlet of the air purifier is roughly the same as the diameter of the centrifugal wind wheel, and the air inlet is narrow, so the amount of air sucked into the air duct is small, the amount of purified air is also small, the efficiency of the motor is low, and the air is sucked into the air from the air inlet through the filter. When the air is in the air, the external air cannot pass through all corners of the surface of the filter screen. The filter screen near the air inlet, that is, the middle part of the filter screen, has high efficiency, and the rest of the filter screen has low efficiency, and the filter screen cannot maximize the use efficiency. For example...

[0002] The air inlet of the air cleaner currently on the market is set on one side, and the centrifugal wind wheel is opened on one side. The size of the air inlet of the air purifier is roughly the same as the diameter of the centrifugal wind wheel, and the air inlet is narrow, so the amount of air sucked into the air duct is small, the amount of purified air is also small, the efficiency of the motor is low, and the air is sucked into the air from the air inlet through the filter. When the air is in the air, the external air cannot pass through all corners of the surface of the filter screen. The filter screen near the air inlet, that is, the middle part of the filter screen, has high efficiency, and the rest of the filter screen has low efficiency. The filter screen cannot maximize the use efficiency.

For example, the air conditioner with a new type of air intake system announced by the Chinese Invention Application Published Patent (Application No. 201210277744.9) has additional air inlets on both sides of the air conditioner and holes on the outer edge of the air duct, so that the air from the air inlets on both sides passes through the outer edge of the air duct. Bypassing the rear side of the air duct to enter the air, although the above-mentioned technical solution solves the problems of small air intake into the air duct caused by the small air inlet of the air purifier on the market and the small amount of purified air and small air volume, its structure is complicated, and its The air intake on both sides needs to detour and the loss is relatively large, which has certain limitations

[0003] Moreover, the air inlet of the above-mentioned air purifiers currently on the market is set on one side, and the centrifugal wind wheel is opened on one side. On the same side, and due to the limitation of the internal space structure of the air purifier, the distance between the electrostatic dust collection net and the humidification impeller is relatively close, so its creepage distance and electrical clearance are difficult to meet, so it is impossible to achieve simultaneous additional humidification and electrostatic dust collection functions
