First, as shown in FIGS. 1 and 2, the waterfall-type air purifier 100 according to the present invention includes a housing 110 having a hollow portion H through which air flows in a central portion thereof, and the housing ( The upper water tank 120 installed on the upper portion of the 110, the lower water tank 130 installed on the lower portion of the housing 110, the water flow portion 140 provided on the side of the housing 110, and the housing 110 Ventilation pipe 150 installed on one side of the air filter, the air filter 160 installed in the hollow portion (H) of the housing 110 and the air blower (or lower) installed on the upper side (or lower) of the air purification filter 160 ( 170).

Therefore, when water is supplied to the upper tank 120 by the plumbing pipe 150, water flowing down from the upper tank 120 falls along the water flow section 140 and is artificial in the process of being stored in the lower tank 130. Allow them to form waterfalls.

In particular, while the artificial waterfall is formed as described above, the air purification by the waterfall water in the process of discharged through the hollow portion (H) of the housing after the air passes through the vent (AT) provided in the water flow portion 140 To be done.

In addition, the purified air contains a large amount of moisture to ensure that the indoor humidity is properly maintained, as well as to enhance the aesthetics by the interior effect of the artificial waterfall itself.

In addition, the plumbing pipe 150 not only supplies the waterfall to the upper tank 120, but also, if necessary, the water stored in the lower tank 130 can be used as heavy water by supplying water to the water tank (not shown) of the toilet bowl. To save money.

To this end, the housing 110 has an upper end and a lower end, and has a cylindrical shape having a hollow part H used as a passage through which air flows. Therefore, the air introduced into the hollow part H inside the housing 110 through the vent part AT of the water flow part 140 may be discharged to the outside (ie, the air conditioning space).

In addition, the upper tank 120 is installed on the upper portion of the housing 110, the lower tank 130 is installed on the lower portion of the housing 110, the water flow portion 140 is installed on the side of the housing 110, In this case, the water flow portion 140 may be a side portion (ie, a side wall) of the housing 110 itself.

Furthermore, the housing 110 has a cylindrical shape having a circular cross section, as can be clearly seen through FIG. 2. Therefore, by installing the water flow portion 140 along the circumferential direction of the housing 110, the artificial waterfall is also formed in all directions, and the contact area between the air and the waterfall of the artificial waterfall (hereinafter referred to as 'water') is maximized. Allow air purification to be accomplished in a short time.

Of course, in addition to the cylindrical shape described above, a variety of shapes, such as an pottery shape, are possible for the natural fall of water.

The upper water tank 120 installed in the upper portion of the housing 110 is installed in the upper end of the housing 110, the upper edge of the housing 110, that is installed over the entire direction along the circumferential direction of the upper end of the housing 110 And a space part in which water is stored. In addition, one side is provided with a supply hole (not shown) to receive water through the piping system 150. Therefore, when water is supplied through the supply hole to fill the upper water tank 120, the water overflowing from the upper water tank 120 flows along the water flow portion 140 to extend in all directions (ie, 360 °). Allows the formation of artificial waterfalls.

In particular, the partition of the upper tank 120 in which water is temporarily stored is provided with a partition wall 123 for partitioning the space into two zones, so that the upper tank 120 is divided into a first upper tank 121 and a second tank. The upper tank 122, which is close to the center side of the housing 110, the first upper tank 121, near the outside of the housing 110 is the second upper tank 122.

In addition, a plurality of water flow ports 123a are formed at the lower end of the partition wall 123 so that water stored in the first upper water tank 121 is supplied to the second upper water tank 122 through the water flow ports 123a. When the second upper tank 122 is full, water flowing from the second upper tank 122 flows along the water flow unit 140 to form an artificial waterfall.

Therefore, when there is no partition wall 123 having the drain port 123a, the water inclination occurs in the upper tank 120 due to the pressure of the water being supplied from the piping system 150, or stored in the upper tank 120 It is possible to prevent the phenomenon that the water flows and the flow of water supplied to the water flow part 140 is unnaturally cut off.

That is, the partition wall 123 partitioning the upper tank 120 serves as a resistance to water, thereby preventing the above-mentioned slump and the like from occurring in the water stored in the second upper tank 122, and at the same time, the drain 123a. By supplying a fixed amount of water at a constant speed through the) to supply a stable and continuous water to the second upper tank (122).

The lower water tank 130 installed below the housing 110 has a space portion in which water is stored, similar to the upper water tank 120, and is located at an appropriate position to receive and store the water dropped along the water flow portion 140. It is installed, the water stored in the lower tank 130 through the circulation discharge hole (not shown) and the piping system 150 to supply water to the upper tank 120 through the piping system 150 is used as heavy water. Heavy water discharge holes (not shown) are formed to discharge.

Therefore, the water which overflows from the upper tank 120 and falls along the water flow unit 140 to form an artificial waterfall is collected and stored in the lower tank 130, and thus the water stored in the lower tank 130 is circulated A circulation cycle is formed to be supplied to the upper water tank 120 again through the discharge hole.

In addition, if necessary, the water stored in the lower water tank 130 may be discharged through the heavy water discharge hole so as to be used as heavy water such as being supplied to the water bottle of the toilet. Of course, when the water stored in the lower tank 130 is used as heavy water, when the water is insufficient, it is possible to receive a constant such as tap water from the outside.

However, since the lower tank 130 described above is not directly related to the formation of the artificial waterfall and only serves to collect water after the artificial waterfall is formed, the rectangular tank as shown more clearly through FIG. 2. May be used, but various other shapes are possible.

In addition, the lower tank 130 is preferably a drawer type lower tank 130 that can be pulled in and pulled out. For this purpose, the lower tank 130 is, for example, an outer fixing frame 131 and an inner side of the fixing frame 131. And a drawer-type water tank 132 installed to be slidable therein. Therefore, when the use is stopped to empty the water stored in the lower tank 130, or when cleaning the lower tank 130 to draw the drawer-type tank 132 in a sliding manner to perform the above operation. Do it.

In addition, the lower water tank 130 is provided with a water level detection device (not shown) for detecting the height of the water stored in the lower water tank 130, when the water level detection device detects the height of the water is low, the water supply pipe By automatically adjusting the supply valve installed in 152, the shortage of water is automatically replenished through the water supply pipe 152.

The water level sensing device is similar to a configuration in which, for example, a buoy installed in a water bottle of a toilet bowl and water is automatically supplied when the buoy descends. Therefore, hereinafter, a more detailed description of the level sensor will be omitted.

The water flow portion 140 installed on the side of the housing 110 is to guide the fall of the water supplied overflowed from the upper tank 120 (exactly the second upper tank 122) to form an artificial waterfall, as described above As described above, the side of the housing 110 is separately installed, or the water flow portion 140 itself forms the side wall of the housing 110.

However, the water flow portion 140 in the present invention is installed on the side of the housing 110, preferably installed or configured over the entire direction along the outer peripheral surface of the housing 110, the housing 110 as described above Allow artificial waterfalls to form in all directions.

In addition, the water flow unit 140 itself is provided with a vent (AT) so that the air flows through the artificial waterfall and the vent (AT) of the water flow unit 140 so that the air is purified by water. In particular, the water flow portion 140 is installed in all directions along the outer circumferential surface of the housing 110 to maximize the contact area of air and water and to allow air purification to be performed within a short time.

On the other hand, the water flow portion 140 as described above may be composed of a plurality of water flow plates (141 to 143) each having a plate shape. That is, as shown in FIG. 1, which illustrates an example of the water flow unit 140 including three water flow plates 141 to 143, the first water flow plate 141, the second water flow plate 142, and the third water flow plate ( 143 are disposed adjacent to each other with a gap enough to allow the air to pass through, so that the ventilation portion AT is formed between the respective water flow plates.

In addition, it is arranged side by side along the direction of forming the artificial waterfall, that is, the height direction of the housing 110 to guide the flow of water for the artificial waterfall by the first water flow plate 141 to the third water flow plate 143. You can also do it.

In addition, the present invention, as can be seen more clearly through FIG. 3, the lower bent portion 141a bent toward the rear is formed at the lower end of the first water flow plate 141 disposed on the uppermost portion, An upper bent portion 142a bent toward the front side is formed at an upper end of the adjacent second water flow plate 142, and the lower bent portion 141a and the upper bent portion 142a contact each other for air passage. The ventilation unit AT is formed by overlapping each other with a predetermined width while avoiding it.

This also applies to the vent part AT formed in the part adjacent to the 2nd water flow plate 142 and the 3rd water flow plate 143 like FIG.

Therefore, the air flows smoothly through the vent part AT formed by the lower bent portion 141a and the upper bent portion 142a, as well as the first and third water flow plates 141 to 143 of the third water flow plate 143. It is possible to prevent water droplets from splashing or inflowing toward the rear side.

1 to 3, the lower bent part 141a is bent toward the rear side and the upper bent part 142a is bent toward the front side, but the lower bent part 141a is opposite. While bending toward the front side and the upper bent portion 142a is bent toward the rear it will be apparent that the above effects can be generated.

In addition, in the present invention, except for the first water flow plate 141 located at the top, the upper end of the second water flow plate 142 and the upper end of the third water flow plate 143, respectively, the stepped 142b in which water flowing down hits each other. Formed. Therefore, the water hits the step 142b to generate a large number of fine droplets, thereby making it possible to more effectively remove various contaminants contained in the air flowing through the vent (AT).

At this time, if the width of the step 142b is wider than the thickness of the water flow plates 141 to 143, the first water flow plates 141 to the third water flow plates 143 arranged side by side in the up and down direction form a stepped shape, As described above, as well as generating a large number of fine droplets will be able to further enhance the interior effect.

In addition, the present invention, as shown in Figure 4, the projection protruding toward the artificial waterfall side on the front surface of the first water flow plate 141 to the third water flow plate 143 in which the artificial waterfall is formed (that is, the waterfall flows) (P) is formed (or attached), the projections (P) to hinder the flow of water to reduce the rate of falling of the water, as well as to disperse the water to create more fine water droplets to further increase the air purification power. Of course, it is also possible to form a natural artificial waterfall by allowing the water flow to be diversified by the projections (P).

In addition, the present invention, as shown in Figure 5, may be provided with a groove (G) to the predetermined depth on the front surface of the first water flow plate 141 to the third water flow plate 143, such a groove (G) This causes the flowing water to collide with more water droplets. Of course, it also slows down the water's rate of fall by disrupting the flow of water.

However, the groove G may be formed in a bar shape formed long along the width direction of the first water flow plate 141 to the third water flow plate 143 as shown, but a groove having a dot shape. It is possible to provide a variety of other shapes, such as having a plurality.

Furthermore, in the above, the water flow part 140 has been described as an example consisting of three water flow plates 141 to 143 including the first water flow plate 141 to the third water flow plate 143. However, it may be made of more than four water flow plates (not shown), or may be made of less than one or two water flow plates (not shown). However, when the water flow portion 140 is made of one water flow plate (not shown), only a gap between the water flow plate (not shown) and the lower water tank 130 will be used as the vent portion AT.

The piping system 150 installed at one side of the housing 110 is for circulation of water, supply of water and discharge of heavy water, one end of which is connected to the supply hole of the upper tank 120 and the other end of the circulation of the lower tank 130. A water circulation pipe 151 connected to the ball, a water supply pipe 152 connected to the water circulation pipe 151 through a three-way valve (not shown), a heavy water pipe 153 connected to the heavy water discharge hole, and a water circulation pipe ( It includes a circulation valve installed in the 151, a circulation pump 154 provided in the water circulation pipe 151, a supply valve provided in the water supply pipe 152 and a discharge valve provided in the heavy water pipe 153.

Therefore, when the circulation pump 154 operates, the water stored in the lower water tank 130 is supplied to the upper water tank 120 through the circulation discharge hole, the water circulation pipe 151, and the supply hole, and the water continues to the upper water tank 120. To allow for continued formation of an artificial waterfall.

In addition, when the heavy water pump (not shown) is operated, the water stored in the lower tank 130 is supplied to the water tank of the toilet bowl, so as to form an artificial waterfall and to purify the air so that the contaminated water can be used as heavy water. do. However, the water stored in the lower tank 130 may be directly supplied to the water tank of the toilet bowl, etc., but it is obvious that the water may be stored in the heavy water storage tank and resupply to a necessary place.

In addition, when the shortage of water required to form an artificial waterfall using the water stored in the lower tank 130 as a heavy water as described above occurs to receive a constant such as tap water through the water supply pipe 152 to replenish the shortage of water. . In the above, the water supply pipe 152 is connected to the water circulation pipe 151 through a three-way valve, for example, but the water supply pipe 152 is directly installed in the upper water tank 120 or the lower water tank 130. May be

The air purification filter 160 installed in the hollow part H inside the housing 110 is primarily purified by contact with water in the process of passing through the ventilation part AT of the artificial waterfall and the water flow part 140. It is for purifying the air secondary, and is disposed on the flow path of the air.

The air purification filter 160 removes various harmful substances such as odors, harmful gases, harmful chemicals and carcinogens, including activated carbon, biofilters, and various other filters.

The blower 170 forcibly blows air introduced into the hollow part H inside the housing 110 through the vent part AT to be supplied to an air conditioning space such as an indoor room. Include.

In FIG. 1, the air purification filter 160 is installed at the lower side of the blower 170 in the hollow portion H inside the housing 110, but the present invention is not limited thereto. 160 may be installed above the blower 170.

On the other hand, in the above-described embodiment, the water flow section 140 is composed of a plurality of plate-shaped water flow plates (141 to 143). However, in the present invention, as shown in FIGS. 6 and 7, each of the plurality of embossed plates 180 and 190 protruding toward the front portion from which the water flows is arranged to be coupled to each other, and each of the embossed plates 180, 190 is a front end of the polygonal shape, the water flow portion 140 is formed with a vent (AT) may be used in the center.

That is, as shown in Figure 6, the rhombus-shaped frame is provided with a three-dimensional relief plate 180 protruding in the direction toward the artificial waterfall, the center surrounded by the frame is provided with a vent (AT), the inclined frame Therefore, the water flows down to form an artificial waterfall, and the air is flowed through the vent (AT) to purify the air by the water. Then, a plurality of rhombus-shaped relief plates 180 are arranged side by side to form a honeycomb to form the water flow portion 140.

Accordingly, the water flowing along the water flow portion 140 diverges in a plurality of directions to maximize the contact area exposed to the outside, thereby maximizing the contact area of air and water, thereby purifying the air within a short time.

In addition, the interior effect can be enhanced by the three-dimensional shape of the embossed plate 180 itself, of course, in the case of illuminating the corresponding embossed plate, the shade is generated by the three-dimensionally protruding embossed plate, which can have more excellent interior effect. To be.

Furthermore, FIG. 7 illustrates a three-dimensional relief plate 190 having a hexagonal frame protruding in a direction toward an artificial waterfall, and having a vent portion AT formed at the center thereof. However, since the relief plate 190 is similar to that described in FIG. 6, a detailed description thereof will be omitted.

In addition, as shown in FIG. 8, the tubular frame as the water flow unit 140 is disposed to have a polygonal shape, and a tubular water flow view 200 in which a vent part AT is formed at the center surrounded by the tube. In addition, similar effects to the three-dimensional relief plates 180 and 190 described with reference to FIGS. 6 and 7 may also be generated. And, it is obvious that such a tubular water flow part can be various shapes including a rhombus or a hexagonal shape.

On the other hand, it has been described above by taking an example that the casing 110 has a circular cross-section, the waterfall-type air purifier according to the present invention has a generally cylindrical shape. However, the present invention is not limited thereto, and if the artificial waterfall is formed in all directions (ie, 360 °), and the flow of air for cleaning the air can be made in all directions, various other shapes can be applied.

That is, as shown in FIG. 9, the cross section of the housing 210 is formed in a square shape, and thus the upper part partitioned into the first upper tank 221 and the second upper tank 222 by the partition wall 223. The water tank 220 may also have a square shape in cross section. In addition, the water flow unit 240 is also provided on each surface corresponding to the entire outer circumferential surface of the housing 210, thereby generating the same or similar effects as the case where the cross section of the housing 210 is circular.

Of course, as long as the artificial waterfall can be formed in all directions, it will be obvious that various other shapes may be applied, including a pentagonal shape.

Hereinafter, the operation of the waterfall-type air purifier according to the present invention having the configuration as shown in FIG. 1 will be described.

It is supplied to the second upper water tank 122 through the flow hole (123a) formed at the bottom of.

At this time, the first upper tank 121 has a fluctuation due to the water pressure of the water being supplied, but the second upper tank 122 separated from the first upper tank 121 by the partition wall 123 maintains a calm state.

When water is supplied from the first upper tank 121 and the second upper tank 122 is filled with water, the water overflowed from the second upper tank 122 in all directions in the water flow part 140 is then formed. It flows sequentially along the 1st water flow plate 141, the 2nd water flow plate 142, and the 3rd water flow plate 143, and forms an artificial waterfall in all directions.

In addition, through the vents (AT) formed between each of the water flow plates (141 to 143) while the air forcedly sucked by the blower 170, various foreign substances contained in the air is removed and purified by water, In particular, since the artificial waterfall is formed in all directions and the air passes through the artificial waterfall formed in the all directions, air purification can be performed in a short time.

In addition, the water flowing along the first and third water flow plates 141 to 143 hits the step 142b or the projections P formed on the water flow plates 141 to 143 and is pulverized into small droplets to purify the air. When the water flow portion 140 is made of a three-dimensional polygonal relief plate (180, 190) or tubular water flow portion 200, the air purification is made in a short time.

Subsequently, the water stored in the upper water tank 120 flows along the water flow portion 140 as described above, forms an artificial waterfall, and simultaneously purifies the air, and then is collected and stored in the lower water tank 130. Then, the water stored in the lower water tank 130 is raised along the water circulation pipe 151 by the circulation pump 154 and supplied to the upper water tank 120 to continue the water circulation.

On the other hand, the water contaminated by the use of artificial waterfall formation and air purification for a long time is discharged through the heavy water pipe 153 is used as heavy water, and the water generated by the shortage is supplemented by receiving a constant through the water supply pipe 152 As above, the water cycle continues.

Thus, it is possible to continue to remove various contaminants contained in the air and to form artificial waterfalls.
