Description

Wet air cleaner {WET TYPE AIR CLEANER}

This disclosure relates to wet air purifiers.

As environmental pollution worsens due to industrialization and time spent indoors increases, keeping indoor air clean has become more important than anything else. Air purifiers are installed and used in homes and offices to keep indoor air clean.

In general, air purifiers are structured to remove fine dust, etc. from external air using various filtration filters. In the case of a wet air purifier, water is used instead of a filter, and fine dust, etc., is adsorbed and removed by contacting the air with water.

However, in the case of conventional wet air purifiers, it is difficult to effectively bring contaminated air into contact with water, which reduces contamination removal efficiency and makes it difficult to quickly and effectively purify a large amount of air in a wet manner. In addition, since water must be continuously contained within the device, bacteria and the like easily multiply in the water, causing air pollution.

Recently, as the number of casualties increases due to environmental pollution such as yellow dust and fine dust, as well as the spread of serious viruses such as coronavirus, the need for improvements in air purification devices is increasing. Therefore, providing improved technology to more effectively purify indoor polluted air can provide many advantages to users.

This project is to provide a wet air purifier that can effectively collect and process large amounts of air.

This project is to provide a wet air purifier that can maximize the efficiency of air purification by water by effectively contacting polluted air with water.

This project is to provide a wet air purifier capable of preventing water contamination.

This project is to provide a wet air purifier that can effectively sterilize air.

The air purifier of this embodiment includes a housing forming an external shape, an air intake unit disposed above the housing for sucking in external air, detachably installed in a lower part of the housing and communicating with the lower part of the air intake unit, and providing the sucked air. A water tank containing a liquid that collects contaminants contained in the water tank, a spray portion installed at the bottom of the air intake portion to discharge the sucked air in the form of a vortex on the water surface of the water tank, and a water tank formed on a side of the housing and in communication with the water tank. It may include an air outlet for discharging the purified air to the outside.

The air intake unit may include a suction pipe that communicates with an inlet at the top of the housing and extends vertically in a downward direction to communicate with the top of the water tank, and a driving fan installed inside the suction pipe to suck in external air.

The air suction unit may further include a filter installed inside the suction pipe to remove contaminants contained in external air.

The housing may have a structure in which the inlet connected to the air intake unit is inclined at an angle with respect to the horizontal plane.

The spray unit may include a circular bottom plate installed at the bottom of the air intake unit, a plurality of outlets formed at intervals along the circumference of the bottom plate, and a spray pipe installed in communication with the outlet and extending downward.

The injection pipe may have a structure that extends and is inclined downward along a tangential direction of the bottom plate with respect to the vertical direction.

The bottom plate may have a structure in which grooves dug in an arc shape are continuously formed along the circumference where the outlet is formed.

The spray unit may further include a cone-shaped cone member installed at the center of the bottom plate to guide external air toward the outlet.

It may further include a purification unit for sterilizing the water contained in the water tank.

It may further include an air sterilization unit installed in the air discharge unit to sterilize the air discharged to the outside by applying plasma.

The purification unit may include a positive electrode plate and a negative electrode plate, an electrode unit that electrolyzes water to generate hydroxyl radicals (OH), and a power supply unit that applies current to the electrode unit.

The power supply unit includes a terminal portion that is electrically connected to an electrode portion installed inside the water container and installed on the outside of the bottom of the water container, and a fixed terminal portion that is fixed to the bottom of the housing and is electrically connected in contact with the terminal device installed in the water container to apply a current. Therefore, when the water bottle is coupled to the housing, the terminal portion may be connected to the fixed terminal portion.

The air sterilization unit may include a high voltage generator installed inside the discharge passage of the air discharge unit to sterilize and purify contaminants by applying plasma to air discharged to the outside.

According to this embodiment, by sucking in outside air through the top of the device tilted toward the source of contamination, a large amount of outside air can be effectively sucked in and dust can be quickly collected.

In this project, by forming a vortex in the sucked outside air and bringing it into contact with water, all the sucked air comes into contact with the water, and foreign substances such as dust can be more effectively absorbed and removed by the water. Accordingly, the efficiency of air purification using water can be maximized even with the same suction power.

By sterilizing water stored in a boiler by adding hydroxyl radicals, the water can be prevented from being contaminated.

By applying plasma to the dust-collected air discharged through the discharge passage, the efficiency of air acid bacteria purification can be further increased.

However, this is presented as an example, and the present invention is not limited thereby, and the present invention is only defined by the scope of the claims to be described later. The embodiments described below may be modified into various forms without departing from the concept and scope of the present invention. As much as possible, identical or similar parts are indicated using the same reference numerals in the drawings.

The terminology used below is only for referring to specific embodiments and is not intended to limit the invention. As used herein, singular forms include plural forms unless phrases clearly indicate the contrary. As used in the specification, the meaning of "comprising" is to specify a specific characteristic, area, integer, step, operation, element and/or component, and to specify another specific property, area, integer, step, operation, element, component and/or group.

Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings. However, the following example is only a preferred example of the present invention and the present invention is not limited to the following example.

Figure 1 schematically shows the configuration of an air purifier according to this embodiment.

In the following description, the y-axis direction of FIG. 1 is referred to as the up-down direction, the upper part along the y-axis direction is referred to as upper or upper, and the lower part is referred to as lower or lower. Additionally, the xz plane is called a horizontal plane.

As shown in FIG. 1, the air purifier of this embodiment may include a housing 10, an air intake unit 20, a water tank 30 containing liquid, a spray unit 40, and an air discharge unit 50. there is.

The housing 10 forms the external appearance of an air purifier. The housing 10 has a space inside for installation of each component and has an open portion that communicates with the outside for air intake and discharge and replacement of the water tank 30. The size or shape of the housing 10 may be modified in various ways.

The air purifier of this embodiment has an air intake part 20 on the upper part of the housing 10 and an air discharge part 50 on the lower side, and is provided with an air discharge part 50 on the lower side, and is external through the inlet 12 at the top of the housing 10. It may have a structure that sucks in air and discharges purified air through the air discharge part 50 provided on the side of the housing 10. Accordingly, it is possible to effectively inhale and treat polluted external air from any direction.

Additionally, the inlet 12 at the top of the housing 10 connected to the air intake unit 20 may have a structure that is inclined at an angle with respect to the horizontal plane. Accordingly, by directing the inclined inlet 12 at the top of the housing 10 toward the main source of contaminated air, it is possible to more quickly and effectively inhale contaminated external air. For example, in the case of a kitchen, polluted air is mainly generated from the counter where the fire is used, so the efficiency of purification of polluted air can be increased by directing the inclined surface of the top of the housing 10 toward the counter. .

The air intake unit 20 of the present embodiment is in communication with the inlet 12 at the top of the housing 10 and extends vertically along the downward direction to form a suction pipe 22 communicating with the top of the water tank 30, and the inside of the suction pipe 22. It may include a driving fan 24 installed to suck in external air.

The suction pipe 22 may be a cylindrical pipe structure extending vertically. A driving fan 24 is installed on one side along the suction pipe 22. As the driving fan 24 drives, external air is forcibly sucked in through the inlet 12, moves downward along the vertically extending suction pipe 22, and is discharged into the water tank 30.

The air intake unit 20 may further include a filter 26 installed inside the suction pipe 22 to remove contaminants contained in the external air. As shown in FIG. 1, the filter 26 may be at least one selected from, for example, a pre-filter, a catalytic filter, and a deodorizing filter. The filter may be detachably installed inside the suction pipe 22. The type or installation structure of the filter can be modified in various ways.

The external air sucked in through the air intake unit 20 is purified by being sprayed into the water tank 30 located below through the lower outlet of the suction pipe 22.

The water tank 30 is installed in the lower part of the housing 10 and is located directly below the suction pipe 22. For example, the water tank 30 is detachably installed in the housing 10 through a side of the housing 10 and can be inserted into the housing 10 or pulled out. Accordingly, when necessary, the water tank 30 can be removed from the housing 10 to the outside and the water in the water tank 30 can be replaced. The size or shape of the water tank 30 may be modified in various ways.

The water tank 30 may be a container structure that holds water therein. The water tank 30 forms a space inside which can accommodate water, and its upper end is open to communicate with the lower end of the suction pipe 22.

Accordingly, the external air discharged from the lower part of the suction pipe 22 comes into contact with the water surface of the water tank 30, and contaminants can be removed by contacting the water. Then, the air from which contaminants have been removed through contact with water is discharged to the outside of the housing 10 through the air discharge unit 50.

The air discharge unit 50 may include at least one discharge passage 52 formed on the side of the housing 10 and communicating with the upper part of the water tank 30. The discharge passage 52 may be formed continuously along the outer peripheral surface of the housing 10 or may be formed at intervals at predetermined positions.

The external air that flows into the housing (10) through the air intake unit (20) is purified while coming in contact with the water in the water tank (30) and then flows into the housing (10) through the discharge passage (52) connected to the water tank (30). is discharged to the outside.

In this embodiment, the discharge passage 52 is installed at the position where air is sprayed from the suction pipe 22 to the water tank 30, that is, above the height of the bottom of the spray unit 40 that is installed in the suction pipe 22 and sprays external air. can be placed in As shown in FIG. 1, the suction pipe 22 extends further downward past the inner bottom of the discharge passage 52, and the lower end of the injection unit 40 installed at the bottom of the suction pipe 22 is connected to the discharge passage 52. ) is located lower than the bottom.

Accordingly, it is possible to prevent the external air sprayed from the spray unit 40 from escaping directly to the outside of the housing 10 through the discharge passage 52 without being purified by water. Accordingly, the external air sucked into the housing 10 can be discharged through the discharge passage 52 after the contaminants are sufficiently removed while all contacting the water in the water tank 30.

The spray unit 40 discharges the air sucked in from the air intake unit 20 in the form of a vortex to increase the contact force with water. Accordingly, the outside air can be more effectively contacted with water and purified.

Hereinafter, the structure of the injection unit of this embodiment will be described with reference to FIGS. 2 to 5.

As shown, the spray unit 40 is installed at the bottom of the suction pipe 22 and has a structure that discharges the sucked air in the form of a vortex on the water surface of the water tank 30.

For this purpose, the spray unit 40 includes a circular bottom plate 42 installed at the bottom of the suction pipe 22, a plurality of outlets 44 formed at intervals along the circumference of the bottom plate 42, and an outlet 44. It may include a spray pipe 46 that is installed in communication with and extends downward.

The injection pipe 46 of this embodiment may be inclined and extended at a predetermined angle toward the tangential direction of the bottom plate 42 with respect to the vertical direction. That is, the injection pipe 46 has a structure inclined toward the water surface of the water tank 30. The inclined direction and angle of each injection pipe 46 may be the same.

Accordingly, the air discharged from the suction pipe 22 is injected obliquely through each injection pipe 46 connected to the outlet 44, resulting in an overall vortex-like flow. Therefore, the air has directionality and flows in one direction, allowing it to collide more strongly with the water surface.

In this way, the air flowing in the form of a vortex strongly collides with the water surface of the water tank 30, allowing all external air to come into contact with the water. Therefore, all contaminants contained in the outside air can be absorbed into the water, thereby increasing the efficiency of removing contaminants.

Here, the lower end of the suction pipe 22 may form a skirt portion 28 with an inner surface inclined so that the inner diameter gradually decreases. Accordingly, the air flowing into the suction pipe 22 is collected and concentrated toward the spray unit 40 as it passes through the lower skirt part 28, so that it can be sprayed more strongly through the spray unit 40.

The bottom plate 42 is a plate structure that blocks the bottom of the suction pipe 22, and a groove 47 dug in an arc shape can be continuously formed along the circumference where the outlet 44 is formed.

In addition, the spray unit 40 may further include a cone-shaped cone member 48 that is installed at the center of the bottom plate 42 and guides external air toward the outlet 44. The outside air flows along the cone member 48 and into the groove portion 47 on the circumferential side.

In this way, the air flowing into the suction pipe 22 can be more effectively guided to the groove portion 47 by the skirt portion 28 and the cone member 48. Therefore, external air flowing into the suction pipe 22 can be effectively discharged through the outlet 44 formed in the groove 47 while minimizing pressure loss.

Accordingly, by lowering the specifications of the driving fan 24, it is possible to maximize the discharge flow rate of external air through the injection pipe 46 even with a small driving force.

In addition, the air purifier of this embodiment may further include an air sterilizing unit 70 installed in the air discharge unit 50 to sterilize the air discharged to the outside by applying plasma.

The air sterilizing unit 70 may include a high voltage generator 72 that is installed inside the discharge passage 52 of the air discharge unit 50 and sterilizes and purifies contaminants by applying plasma to the air discharged to the outside.

Accordingly, the air passing through the discharge passage 52 is partially converted into ozone and ions by the high voltage energy generated by the high voltage generator 72 and released. The air can be sterilized and purified by these ozone and ions. Accordingly, the air from which contaminants have been removed is sterilized and purified as it passes through the discharge passage 52 and can be discharged to the outside in a clean state.

Additionally, the air purifier of this embodiment may further include a purification unit 60 for sterilizing the water contained in the water tank 30.

The purification unit 60 may include a positive electrode plate and a negative electrode plate, an electrode unit 62 that electrolyzes water to generate hydroxyl radicals (OH), and a power supply unit 64 that applies current to the electrode unit.

When current is applied to the anode and cathode of the electrode unit 62, water is electrolyzed. At this time, the water can be sterilized by the hydroxyl group generated. Since the technology for electrolyzing water is already known, its detailed description will be omitted.

The power supply unit 64 of this embodiment is structured to more easily apply current to the electrode unit 62 provided inside the water tank 30.

To this end, as shown in FIG. 6, the power supply unit 64 is electrically connected to the electrode unit 62 installed inside the water tank 30 and includes a terminal portion 65 installed on the lower outer side of the water tank 30, and a housing ( 10) Including a fixed terminal portion 67 that is fixedly installed on the floor and electrically connected to the terminal portion 65 installed in the water tank 30 to apply current, when the water tank 30 is coupled to the housing 10, the terminal portion 65 ) may be connected to the fixed terminal.

The fixed terminal portion 67 may be installed at a position corresponding to the terminal portion 65 when the water container 30 is coupled to the housing 10.

Accordingly, when the water tank 30 is inserted and coupled into the housing 10, the terminal portion 65 of the water tank 30 and the fixed terminal portion 67 of the housing 10 are electrically connected. Accordingly, the purification unit 60 can be driven by applying current to the electrode unit 62 provided inside the water tank 30.

In this way, by coupling the water tank 30 to the housing 10, current can be easily applied from the power source unit 64 to the electrode unit 62 provided in the water of the water tank 30.

Although exemplary embodiments of the present invention have been shown and described as described above, various modifications and other embodiments will occur to those skilled in the art. These modifications and other embodiments are to be considered and included in the appended claims without departing from the true spirit and scope of the present invention.
