Description

Technical Field

[0001] This utility model relates to the field of air purification, and in particular to an air cleaner. Background Technology

[0002] Chinese patent CN106885312B discloses an air purifier. It features a hollow housing with a water tank-type base at the bottom. A grille-type baffle is located on the front panel of the housing, with a rectangular overflow port at the top. The base is located inside the housing. Below the overflow port are several inverted "V"-shaped gas channels running from the outside in. The housing contains a shell comprising two chambers, one front and one rear. A fan is installed in the front chamber near the baffle, while a composite purification filter material is installed in the rear chamber away from the baffle. The filter material is sealed and surrounded by the rear chamber, with its rear side exposed near the back panel of the housing. A partition separates the front and rear chambers, with an air inlet on the partition. The partition partially covers and tightly fits the front side of the filter material. The fan's intake faces the air inlet, and the top of the front chamber connects to the air outlet on the top of the housing. The aim is to provide an air purifier that achieves thorough water-air mixing, excellent air purification, small footprint, and also functions as a humidifier.

[0003] Chinese patent CN106885312B purifies air by passing it through a grid-type baffle. Its disadvantage is that although it can purify air, the purification efficiency is not high. Some air can pass horizontally through the air cleaner, and the air cleaner's capture rate cannot reach 100%.

[0004] Chinese patent CN116576534A discloses an air cleaner, which includes: a shell, reinforcing ribs, a volute, a first high-pressure water tank, a waterfall plate, a drain plate, a first pump, a circulating water tank, a fan, a filter, a centrifugal impeller, a sewage pump, a base plate, a second high-pressure water tank, a washing and venting rear plate, a washing and venting middle plate, a washing and venting front plate, a water deflector, a rotating shaft, and a second pump. The second high-pressure water tank consists of two interconnected vertical water tanks and one horizontal water tank, with the two vertical water tanks respectively connected to a horizontal water tank. On both sides of the water tank, a door-frame structure is formed. Under the door frame formed by two vertical water tanks and one horizontal water tank, a front washing and venting plate, a middle washing and venting plate, and a rear washing and venting plate are installed in sequence, parallel to the waterfall plate. The upper ends of these plates are fixed to the lower end of the horizontal water tank, and the lower ends are fixed to the drain plate. A water-dispensing wheel is installed on each of the two rotating shafts in the front washing chamber, and a water-dispensing wheel is installed on each of the two rotating shafts in the rear washing chamber. Air enters the air cleaner from the air inlet, and after washing and purification, clean air is discharged from the air outlet.

[0005] The water-pushing wheel in Chinese patent CN116576534A is driven by water falling from a high-pressure water tank, which cannot effectively mix air and water. Utility Model Content

[0006] The purpose of this invention is to overcome the shortcomings of existing air cleaners and provide an air cleaner with an air capture rate of up to 100%.

The sewage pump discharges wastewater outside the outer casing via pipes. The space enclosed by the outer casing and the first drain plate is divided into a water purification zone and a filtration zone by a first partition. An air inlet is located on the outer casing near the water purification zone. Parallel washing front panels, a third water baffle, a second water baffle, and a first water baffle are sequentially fixed inside the outer casing near and parallel to the air inlet. A lower water tank is installed above the washing front panels, third water baffle, second water baffle, and first water baffle. An upper water tank is mounted on top of the lower water tank, and the bottom of the lower water tank... Several drainage holes are provided, leading to the space enclosed by the first drainage plate, the front washing plate, and the third water baffle. The first pump and the second pump are connected to the upper water tank and the lower water tank respectively via pipes. One side of the volute is mounted on the first baffle of the filtration zone, which has several vent holes. A centrifugal impeller and a motor are installed inside the volute, with the motor driving the centrifugal impeller to rotate. The upper end of the volute is connected to the air outlet of the outer shell. A filter bracket is mounted on the other side of the volute, and a filter is installed inside the filter bracket.

A water wheel is installed on the rotating shaft in the space enclosed by the third baffle plate, the front washing plate, the first drain plate and the lower water tank. The motor drives the water wheel and the centrifugal fan to rotate at the same time, so that the air entering the water purification zone is fully washed and purified by the water, and then enters the filtration zone through the first baffle plate. The air then passes through the filter and is discharged clean air from the air outlet of the outer shell above the volute.

[0009] The air cleaner of this utility model further includes a water filter pad, which is installed between a first drain plate and a second drain plate near the lower end of the waterfall panel.

[0010] The air cleaner of this utility model is further equipped with an ultraviolet disinfection lamp inside the water tank.

[0011] In this utility model of an air cleaner, the lower end of the waterfall plate is fixed to the front washing plate by a support rod, and there is a distance between the waterfall plate and the front wall of the outer shell, the rear wall of the outer shell, and the first drain plate.

[0012] The air cleaner of this utility model, wherein: the base plate is a base plate coated with a silver ion plating layer.

[0013] The air cleaner of this utility model includes an overflow hole on the upper water tank, and the upper end of the waterfall plate is fixed to the upper water tank at the lower end of the overflow hole. Water flows out from the overflow hole of the upper water tank and flows down the waterfall plate into the water tank. The waterfall plate has ripples.

[0014] The air cleaner of this utility model, wherein: the first water leakage plate and the second water leakage plate are covered with water inlet holes.

[0015] In this utility model of an air cleaner, the diameter of the air inlet holes of the front washing plate, the third water baffle, the second water baffle, and the first water baffle decreases sequentially.

[0016] In this utility model of an air cleaner, the distance between the front washing plate and the third water-separating plate is 10 to 20 times the distance between the third water-separating plate and the second water-separating plate.

[0017] In this utility model of an air cleaner, the air inlets of the third water baffle, the second water baffle, and the first water baffle are staggered.

[0018] Compared with existing air cleaners, the air cleaner of this invention has the following advantages:

[0019] This utility model of an air purifier draws polluted indoor air into its washing chamber through a centrifugal impeller. A combination of water curtain and water wheel draws the air into the water curtain, where it is fully mixed and circulated to create a washing effect. This process dissolves some substances in the air within the washing chamber into the water, while simultaneously extending the contact time and area between the air and water, allowing harmful substances to fully dissolve and significantly enhancing the purification capacity.

[0020] The second pump pumps water into the lower water tank. The water is sprayed onto the water wheel through the hole at the bottom of the lower water tank. The water wheel is driven to rotate at high speed by the rotating shaft. In the water purification zone, water and air mix at high speed. Then, under the negative pressure of the centrifugal impeller, the air and water are drawn into the filter. The filter removes the water from the air, and the clean air is drawn into the air duct of the centrifugal impeller and discharged from the air cleaner through the volute.

[0021] Compared to existing technologies, the water turbine, driven by an electric motor, breaks the water into smaller pieces, allowing the water to dissolve more fully with the air and thus better removing dust from the air. Attached Figure Description
