In the following description, the same reference numerals are used for the same elements, and overlapping descriptions are omitted unless described in other drawings.

Advantages and features of the disclosed embodiments, and methods of achieving them, will become apparent with reference to the embodiments described below in conjunction with the accompanying drawings. However, the present invention is not limited to the embodiments disclosed below, but may be implemented in various different forms, and only these embodiments allow the disclosure of the present invention to be complete, and common knowledge in the art to which the present invention pertains It is only provided to fully inform those who have the scope of the invention.

1 is a structural diagram abstracting the configuration of an embodiment of the wet air purifier 100 .

The wet air purifier 100 may include an air intake unit 110 , an air purification unit 120 , and an air discharge unit 130 . The wet air purifier 100 may additionally include a component necessary for air purification according to an embodiment.

The air intake unit 110 sucks air from the outside of the wet air purifier 100 . The air intake unit 110 may include an impeller (not shown) for air intake. The wet air purifier 100 may include a rotating shaft (not shown) therein. And an impeller may be installed on the rotating shaft. By rotation of the impeller, air may be introduced from the outside.

According to an embodiment, the air intake unit 110 may include a water supply unit for supplying washing water to the impeller. And the impeller of the air suction unit 110 may include a spray nozzle for spraying washing water. The spray nozzle is formed at the wing tip of the impeller, and as the impeller rotates, the washing water may be sprayed into the air. Accordingly, the air intake unit 110 may serve as a water filter. In addition, the air primarily purified by the air intake unit 110 may be introduced into the air purification unit 120 .

The air purification unit 120 includes a water filter that purifies air by spraying washing water. The water filter of the air purification unit 120 may include an inner wall 122 , a washing water sprayer 124 , and a water tank 126 . Also, according to an embodiment, the water filter of the air purification unit 120 may additionally include other components.

The washing water sprayer 124 is connected to the water tank 126 , and washing water is supplied from the water tank 126 to the washing water sprayer 124 . And the washing water injector 124 is installed on the rotating shaft, and may be rotated by a power means such as a motor. The washing water sprayer 124 may include a centrifugal impeller and a spray nozzle. By applying pressure to the washing water in the injection direction by the centrifugal impeller, a water pressure sufficient to spray the washing water is generated in the direction in which the injection nozzle is located. Then, the washing water in the form of small water droplets is sprayed in a predetermined direction by the nozzle having a fine hole. In the spray nozzle, the size and number of holes of the nozzle may be designed so that the washing water is sprayed at an appropriate spray speed and spray direction according to the water pressure generated by the centrifugal impeller.

Washing water in which air contaminants are deposited is collected along the inner wall 122 and into the water tank 126 by gravity.

After a part of the washing water sprayed from the washing water sprayer 124 collides with the inner wall 122 , it does not flow into the water tank 126 and is adsorbed to the inner wall 122 may occur. Accordingly, there may be a problem that bacteria and mold grow in the wet air purifier 100 due to the contaminated washing water adsorbed on the inner wall 122 . According to an embodiment, it is possible to prevent the washing water from adsorbing to the inner wall 122 by configuring the inner wall 122 with a hydrophobic material.

For example, the inner wall 122 may be coated with a hydrophobic chemical. The hydrophobic chemical may include a fluororesin such as Teflon. In addition, by spraying a liquid fluororesin on the inner wall 122 or immersing the inner wall 122 in a liquid fluororesin, the inner wall 122 may be coated with a chemical material.

Alternatively, by adding a microstructure pattern to the inner wall 122 , the inner wall 122 can be converted to hydrophobicity. The microstructure pattern of the inner wall 122 is described in detail in FIG. 2 .

The inner wall 122 may be designed to collect the washing water into the water tank 126 along the flow path. The flow path may be physically and/or chemically designed. For example, the inner wall 122 may be designed so that there is a groove in the portion where the washing water flow path is. Alternatively, the inner wall 122 is designed so that the portion of the inner wall 122 with the flow path of the washing water is made of a hydrophilic material, and the rest of the inner wall 122 is made of a hydrophobic material, so that the washing water is collected in the portion made of the hydrophilic material. can

In addition, the washing water sprayer 124 may also be implemented with a hydrophobic material. Accordingly, as the adsorption force between the washing water injector 124 and the washing water is weakened, the washing water may be scattered from the washing water injector 124 with minimal energy. Therefore, by implementing the washing water injector 124 as a hydrophobic material, the amount of energy used for air purification can be reduced.

FIG. 2 is a diagram illustrating the inner wall 122 and/or the inner wall 220 of a microstructure that can be applied to the washing water sprayer 124 .

On the left side of FIG. 2 , the inner wall 200 having a planar structure and water droplets 210 adsorbed thereto are shown. And on the right side of FIG. 2 , the inner wall 220 having a hydrophobic microstructure and water droplets 230 adsorbed thereto are shown.

Gravity 212 in the ground direction and resistance force 214 in the opposite direction to the ground direction act on the water droplet 210 . In the case of the inner wall 200 having a planar structure, the resistive force 214 acting on the water droplet 210 may be greater than the gravity 212 . Accordingly, the water droplet 210 may be adsorbed to the inner wall 200 of the planar structure without falling to the ground.

Similarly, the gravity 232 in the ground direction and the shear force 234 in the opposite direction to the ground direction also act on the water droplet 230 . However, in the case of the microstructured inner wall 220 , the resistive force 234 acting on the water droplet 230 may be smaller than the gravity 232 . Accordingly, the water droplets 230 may fall to the ground without being adsorbed on the inner wall 220 of the microstructure.

The difference between the inner wall 200 of the planar structure and the inner wall 220 of the hydrophobic microstructure is the resistance force acting on the water droplets 210 and 230 . The resistance force is determined by the adhesive force between the water droplets 210 and 230 and the inner walls 200 and 220 and the shear force acting on the water droplets 210 and 230 . The adhesive force between the water droplets 210 and 230 and the inner walls 200 and 220 and the shear force acting on the water droplets 210 and 230 are determined according to the contact surface between the water droplets 210 and 230 and the inner walls 200 and 220 . Therefore, the resistive force acting by the inner wall 200 and the water droplet 210 having a large contact surface is greater than the resistive force acting by the inner wall 220 and the water droplet 230 having a narrow contact surface.

Specifically, the contact surface between the inner wall 220 of the microstructure and the water droplet 230 is minimized by the uneven microstructure pattern. In addition, since an air layer is formed between the inner wall 220 and the water droplet 230 having a microstructure, the water molecules of the water droplet 230 and the water molecules of the inner wall 220 are not attracted to each other, but rather agglomerate between the water molecules of the water droplet 230 . tends to be stronger. Accordingly, the shape of the water droplet 230 is closer to a circle than that of the water droplet 210 . As a result, the adhesive force and shear force between the inner wall 220 of the microstructure and the water droplet 230 are reduced, and the inner wall 220 of the microstructure becomes hydrophobic.

According to an embodiment, a piezoelectric element may be provided on the inner wall 122 . The piezoelectric element refers to an element capable of converting mechanical energy into electrical energy according to a piezoelectric effect of generating a voltage by a mechanical external force. When the piezoelectric element is provided on the inner wall 122 , the washing water scattered by the washing water sprayer 124 collides with the piezoelectric element, and electrical energy may be generated according to the piezoelectric effect. And the generated electrical energy may be used for air purification of the wet air purifier 100 . Therefore, since the piezoelectric element is provided on the inner wall 122 , energy required for the wet air purifier 100 can be saved. The piezoelectric element provided on the inner wall 122 is described in detail with reference to FIG. 3 .

FIG. 3 is a view for explaining the piezoelectric element 300 provided on the inner wall 122 .

The piezoelectric element 300 refers to an element that converts mechanical energy into electrical energy according to the piezoelectric effect. The piezoelectric effect is caused by the deformation of a material containing an electric dipole. Specifically, when a mechanical force is applied to a material including an electric dipole, the density or polarization direction of the electric dipole may change. For example, when a force that causes a material to contract is applied, the density of the electric dipole increases. Conversely, when a force is applied to expand the material, the density of the electric dipole decreases. As the electric dipole density of a material changes, a change in the electric field inside the material occurs. And according to the change of the electric field, electricity may be generated in the circuit connected to the piezoelectric element.

According to FIG. 3 , the piezoelectric element 300 is installed inside the inner wall 122 so that the water droplets 310 sprayed from the washing water sprayer 124 collide. When the water droplet 310 collides with the piezoelectric element 300 , the piezoelectric element 300 contracts. And the contracted piezoelectric element 300 expands back to its original size according to the restoring force. Accordingly, due to the vibration of the piezoelectric element 300 due to the collision with the water droplet 310 , electricity may flow in the circuit 320 connected to the piezoelectric element 300 .

A plurality of piezoelectric elements 300 may be installed inside the inner wall 122 . Accordingly, the mechanical energy of the water droplets generated from the rotational energy of the washing water injector 124 may be recovered in the form of electrical energy by the plurality of piezoelectric elements 300 .

According to an embodiment, the water tank 126 may include a sensor for detecting the degree of contamination of the washing water. In addition, when the degree of contamination of the washing water detected by the sensor is greater than or equal to a predetermined threshold, a warning signal may be generated by the processor (not shown) controlling the wet air purifier 100 .

According to an embodiment, the water tank 126 may be connected to water and sewage. And when the degree of contamination of the washing water detected by the sensor is equal to or greater than the threshold value, the contaminated washing water of the water tank 126 is discharged through the water supply and sewerage by the processor (not shown) controlling the wet air purifier 100, Clean water can flow in.

The air discharge unit 130 discharges the air purified by the air purification unit 120 to the outside. The air discharge unit 130 may be implemented as a passage for discharging air according to the flow of air. In addition, the air discharge unit 130 may include an impeller, and may be designed to actively discharge air.

The nozzle 416 may be designed in the form of a column having a narrow upper surface and a wide lower surface. And since there is a fine hole in the side surface of the nozzle 416, the washing water can be scattered at a specific angle from 0 to 90 degrees. For example, the nozzle 416 may be designed to scatter the washing water at an angle of about 15 to 75 degrees. In FIG. 4 , the ejection path of the washing water scattered from the nozzle 416 is shown by a long broken line.

Washing water may be sprayed toward the inner wall 402 by centrifugal force according to the rotation of the washing water sprayer 404 . In addition, the washing water in which air contaminants are deposited is collected along the inner wall 402 and into the water tank 406 by gravity. 4, the recovery path of the washing water is shown by a short broken line.

In addition, since a piezoelectric element is installed on the inner wall 402 , energy required for air purification can be saved. And by configuring the washing water sprayer 404 with a hydrophobic material, it is possible to minimize the energy required for the scattering of the washing water.

The inner wall 502 may be designed in a cylindrical shape centered on the washing water sprayer 504 . The washing water sprayer 504 is disposed on the rotating shaft 508 and may receive washing water from the water tank 506 through a water supply pipe disposed on the rotating shaft 508 .

The washing water sprayer 504 may be composed of a centrifugal impeller 514 and a nozzle 516 . A cylindrically designed nozzle 516 may be positioned to cover the centrifugal impeller 514 . Since there is a fine hole in the side surface of the nozzle 516, the washing water may be scattered in the side direction. In FIG. 5 , the ejection path of the washing water scattered from the nozzle 516 is shown by a long broken line.

Washing water may be sprayed toward the inner wall 502 by centrifugal force according to the rotation of the washing water injector 504 .

6 is an abstract structural diagram of an embodiment of a wet air purifier 600 including a plurality of air purifiers.

Unlike the wet air purifier 100 of FIG. 1 , the wet air purifier 600 may include an air purifier 620 including a plurality of water pumps in order to enhance the air purifying effect. Accordingly, the wet air purifier 600 may include an air intake unit 610 , an air purification unit 620 including a plurality of water filters, and an air discharge unit 630 . In addition, the wet air purifier 600 may additionally include a configuration necessary for air purification according to an embodiment. The air intake unit 610 and the air discharge unit 630 of FIG. 6 may perform substantially the same functions as the air intake unit 110 and the air discharge unit 130 of FIG. 1 .

The air purification unit 620 may include an inner wall 622 , N wash water sprayers, and a water tank 628 . In FIG. 6 , the N wash water sprayers are configured of a first wash water sprayer 624 to an Nth wash water sprayer 626 . N is a natural number.

The first washing water injector 624 to the Nth washing water injector 626 are connected to the water tank 628 , and washing water is supplied from the water tank 628 to the first washing water injector 624 to the Nth washing water injector 626 . do.

In addition, since a piezoelectric element is installed on the inner wall 622 , energy required for air purification can be saved. In addition, by configuring the first washing water injector 624 to the N-th washing water injector 626 with a hydrophobic material, it is possible to minimize the energy required for scattering of the washing water.

The position and shape of the inner wall 622 and the first washing water injector 624 to the N-th washing water injector 626 may be easily changed by a person skilled in the art for air purification efficiency. In addition, the water tank 628 of FIG. 6 may be designed to perform the same function as the water tank 126 of FIG. 1 .

7 is an abstract structural diagram of an embodiment of a wet air purifier 700 having a temperature control device.

Unlike the wet air purifier 100 of FIG. 1 , the wet air purifier 700 may additionally include a temperature control device to enhance the air purification effect and add a humidity control function. Accordingly, the wet air purifier 700 may include a heater 740 and a cooler 750 of the compressor as well as the air intake unit 710 , the air purification unit 720 , and the air discharge unit 730 . The air intake unit 710 , the air purification unit 720 , and the air discharge unit 730 of FIG. 7 are substantially the same as the air intake unit 110 , the air purification unit 120 and the air discharge unit 130 of FIG. 1 . can perform the same function.

The heater 740 is physically connected to the air purification unit 720 to supply thermal energy to the air purification unit 720 . The heater 740 may be physically connected to the washing water injector 724 of the air purification unit 720 to supply thermal energy to the washing water injector 724 . By the heater 740, the washing water sprayer 724 is heated to a high temperature, so that water particles can be scattered smaller.

The cooler 750 is physically connected to the air discharge unit 730 to absorb thermal energy of the air discharge unit 730 . Accordingly, since the air discharge unit 730 is cooled by the cooler 750 , the water vapor contained in the air discharged from the air discharge unit 730 is liquefied. Accordingly, the humidity of the air discharged from the air discharge unit 730 may be adjusted by using the heat energy absorption function of the cooler 750 .

According to an embodiment, if the humidity in the room needs to be increased, only the heater 740 is activated and the cooler 750 is deactivated, so that the wet air purifier 700 may serve as a humidifier. In addition, when indoor humidity needs to be kept low, by activating both the heater 740 and the cooler 750 , the humidity of the air discharged from the air discharge unit 730 can be lowered.

According to an embodiment, the processor (not shown) of the wet air purifier 700 may control the amount of heat energy absorbed by the cooler 750 to adjust the humidity of the air discharged from the air discharge unit 730 . In addition, the cooler 750 absorbs heat energy according to the amount of heat energy absorbed by the processor, so that the humidity of the air discharged from the air discharge unit 730 may be constantly maintained.

The heater 740 and the cooler 750 may be specifically implemented using a compressor. For example, the heater 740 and the cooler 750 may be implemented as a condenser and an evaporator of a compressor. Specifically, the condenser of the compressor serving as the heater 740 compresses the vaporized refrigerant and then liquefies the compressed refrigerant at a low temperature, thereby releasing thermal energy. And, the evaporator of the compressor serving as the cooler 750 scatters the liquefied refrigerant in the form of water droplets in a low-temperature and low-pressure environment, and then vaporizes the scattered refrigerant to absorb thermal energy around the cooler 750 .

The heater 740 and the cooler 750 may be implemented as separate and separate devices. For example, the heater 740 may be implemented as a device for emitting thermal energy, such as a gas heater, a steam heater, a high frequency induction heater, or the like. In addition, the cooler 750 may be implemented as a cooling device that is separated from the heating device and absorbs thermal energy. The cooling device may be a direct expansion chiller, an absorption chiller, a cryogenic chiller, or the like. When the heater 740 and the cooler 750 are separately separated, the heat exchange depicted in FIG. 7 does not occur.

The technical features of the wet air purifiers 100 , 400 , 500 , 600 , and 700 of FIGS. 1 and 4 to 7 may be implemented in various physical forms. In addition, FIGS. 1 and 4 to 7 are only examples for explaining the technical characteristics of the wet air cleaners 100, 400, 500, 600, and 700, and the wet air cleaners 100, 400, 500, 600, and 700 are illustrated in FIGS. The scope of rights is not limited by the appearance and design of And the design details and appearance of each component described in FIGS. 1, 6 and 7 can be easily derived by a person skilled in the art related to the air purifier.

In addition, a user may input a command to the wet air purifiers 100 , 400 , 500 , 600 and 700 through a user interface (not shown). The wet air purifiers 100 , 400 , 500 , 600 , and 700 may include a computer-readable recording medium (not shown) in which a program including instructions for performing its function is stored. The program may be stored in a computer-readable recording medium, and may be uploaded or downloaded online.
