Description

Humidifying type air cleaner

The present invention relates to a humidifying air purifier that purifies contaminated air through water particles as if it is washed with water. More specifically, it is possible to improve air purification efficiency through a two-step air purification process using water. In addition, by varying the spray angle of water particles, by spraying water particles of different sizes, the spray distribution of water particles can be made uniform to increase the adsorption efficiency of pollutants in the air, and to purify air using water for a long time. The present invention relates to a humidifying air purifier that is easy to maintain because it can minimize the reduction in air purification efficiency.

In general, an air purifier is a device that sucks polluted air in a room and passes the sucked air directly through an air purification filter to remove contaminants such as dust contained in the air and then discharges it to the outside using a fan. In addition, a humidifier is a device that artificially evaporates water or sprays water particles to control indoor humidity, and an air purifier that has been added to a humidifying function in addition to the air purifying function has been continuously developed and proposed, especially in recent years. Attempts are being made to actively utilize polluted air instead of using it as a humidification function.

As an example, in the registered utility model No. 20-0291824 (name of the draft: 'air purifier'), a plurality of water film plates are installed at regular intervals between the air inlet and the air outlet, and water flows along the water film plate. It is made to flow down, and a plate with an open top is installed between each water film plate so that the air introduced into the air inlet passes sequentially through the lower part of the water film plate and the upper part of the plate, and whenever the air passes through each water film plate It is configured to purify the air by adsorbing and removing foreign substances from the air in the flowing water, and discharging and removing the foreign substances to the outside.

A large number of water film plates and plates are provided in front of the air inlet, so the air discharge amount is low compared to the air intake amount, reducing the operating efficiency of the fan that flows in and out, and the inflow air is not completely mixed with the water of the water film plate, so foreign matter in the air is missing. There is a problem that is discharged to the outside without being adsorbed on the water.

As another example, in the registered utility model No. 20-0180739 (the name of the draft: 'air purifier), a water tank is provided at the bottom of the air purifier, and the water tank is provided with a water tank with a blower blade at the upper side so that the lower side of the rotary porous tube is locked. It is provided, the inside of the rotating perforated pipe is provided with a screw for flowing the water of the bucket to the upper side of the rotating perforated tube, the rotating perforated tube, the blower wing, and the screw rotates together to store the water stored in the water bottle inside the rotating perforated tube The water moved upward, and the water moved upward inside the rotating porous tube by the rotational movement of the screw is sprayed to the outside along a plurality of holes provided on the surface of the rotating porous tube by the centrifugal force of the rotating porous tube, thereby allowing a plurality of water streams Forming, the air introduced into the air purifier by the rotation of the blower blades, the air introduced while contacting the plurality of water streams After pollutants are adsorbed on the stream, purified air is discharged to the outside.

There is a problem in that the air purification efficiency is low by purifying the air through only the purification step of the first step of adsorbing contaminants in the air as the water stream injected through the rotating porous tube, and the water flowing through the rotating porous tube is air There is a problem that the contact rate with the air falls because it is not sprayed evenly inside the flowing space but is sprayed only on the wall of the cylinder, and when it is used for a long time, there is a problem of re-contamination due to water or moss caused by water stored inside the bucket. There is a problem in that maintenance is cumbersome because the water in the bucket must be discharged frequently and the scale or moss inside the bucket must be removed.
