The present invention relates to a humidified air purifier.

An air purifier is understood as a device that inhales and purifies contaminated air and then exhausts the purified air. As an example, the air cleaner may include a blower for introducing external air into the air cleaner and a filter capable of filtering dust or bacteria in the air.

A humidifier is understood as a device that sucks in air, humidifies it, and discharges it to provide moisture to the air. Conventional humidifiers are divided into a vibrating type that atomizes water from a diaphragm and discharges it into the air, and a natural evaporation type that naturally evaporates from a humidifying filter.

The natural evaporative humidifier rotates the disk using a driving force, and a disk-type humidifier in which water is naturally evaporated from the surface of the disk in the air, and a humidifying filter-type humidifier that is naturally evaporated by air flowing in a humidified medium soaked with water. Are distinguished.

In the conventional humidifier, some of the air flowing in the humidification process was filtered by the filter. However, the conventional humidifier has a problem in that the function of purifying air is weak because the humidifying function is main.

In recent years, humidifying air purifiers have been developed that add a humidifying function to an air cleaner.

11 is a perspective view showing the configuration of a first guide among flow guides according to an embodiment of the present invention, and FIG. 12 is a perspective view showing the configuration of a second guide among flow guides according to an embodiment of the present invention, FIG. 13 Is a cross-sectional view taken along line XIII-XIII 'of FIG. 7. 11 and 12, the first and second guides 341 and 342 will be described in more detail.

The first flow guide 341 according to an embodiment of the present invention may have a plate shape. In detail, in the first flow guide 341, the plate-like first guide body 341b extending in the vertical direction and the first guide body 341b extend forward and round to discharge air from the main body 320. A first bent portion 341a which guides to the front side is included.

The first guide body 341b and the first bent portion 341a may be configured to have a first width w1 in a relatively small front-rear direction.

The first bent portion 341a may be formed to have a first radius of curvature Ro based on the center of curvature Co. In addition, the first bent portion 341a may shield an upper portion of the first discharge flow path 351.

The air flowing through the first discharge passage 351 flows from the front of the first guide body 341b upwards, and is guided by the first bent portion 341a to flow forward. In addition, the air may be guided to a discharge hole 325 positioned at a lower portion among the plurality of discharge holes 325.

The second flow guide 342 according to the embodiment of the present invention may have a bar shape. In the second flow guide 342, a bar-shaped second guide body 342b extending in the vertical direction and extending forwardly from the second guide body 342b are forwardly rounded to discharge air in front of the discharge body 320. A second bent portion 342a that guides to the side is included.

The width of the second flow guide 342 in the front-rear direction may be larger than that of the first flow guide 341 in the front-rear direction. In detail, the second width w2 in the front-rear direction of the second guide body 342b and the third width w3 in the front-rear direction of the second bent portion 342a are formed larger than the first width w1. Can be. Here, the third width w3 may be the width of the upper surface of the second bent portion 342a.

The second bent portion 342a is in contact with the inner surface of the upper end of the discharge body 320, and the third width w3 may correspond to the front and rear widths of the discharge body 320. That is, the second bent portion 342a may be configured to fill the upper space of the discharge body 320. Therefore, the discharged air does not flow to the upper end of the discharge body 320, and may be discharged forward along the rounded surface of the second bent portion 342a. As a result, it is possible to prevent vortices from being generated in the upper space of the discharge body 320.

The second bent portion 342a may be formed to have a second radius of curvature R1 based on the center of curvature C1. The first radius of curvature Ro and the second radius of curvature R1 may form the same value.

In addition, the second bent portion 341a may shield the upper portion of the third discharge flow path 359. The third discharge flow path 359 is a discharge flow path through which the air passing through the second discharge flow path 355 passes, and is formed above the first flow guide 341.

A separation portion 357 is formed between the upper end of the first flow guide 341 and the lower end of the second flow guide 342. The separation portion 357 communicates with the second discharge flow path 355 and the third discharge flow path 355, and bends forward from the second discharge flow path 355 toward the third discharge flow path 359. The room can be understood as a "connection euro".

The air in the second discharge passage 355 flows to the front upper portion of the discharge body 320 while passing through the spacer 357 and flows through the third discharge passage 359. The air flowing through the third discharge passage 359 flows from the front of the second guide body 342b upwards, and is guided by the second bent portion 342a to flow forward. In addition, the air may be guided to a discharge hole 325 positioned at an upper portion among the plurality of discharge holes 325.

Referring to FIG. 7, the discharge area or flow cross-sectional area (S) of the discharge body 320 is the front-rear width A and the left-right direction width (A) of the first discharge part 320a or the second discharge part 320b ( It can be defined by the product of B) (S = A * B). With respect to the discharge area S, the size of the left and right widths d1 of the discharge hole 325 may be determined in consideration of discharge air volume and noise.

If the size of the left and right widths d1 is too large, a flow rate may decrease when air passes through the discharge hole 325, and thus air may not be discharged far from the air conditioner 10. On the other hand, if the size of the left and right widths d1 is too small, flow separation occurs when air passes through the discharge hole 325, and thus noise is generated.

Considering this, in the embodiment of the present invention, when the ratio of S to d1 is 2,000 or less, it was confirmed through experiments that the discharge air volume is relatively large and noise is reduced. For example, when the flow rate of the fan 280 is 3 to 4 (CMM), the size of d1 may be formed to be 1.5 to 2.5 mm.

14 is a cross-sectional view showing air flow in a humidified air purifier according to an embodiment of the present invention.

Referring to FIG. 14, air flow in the air cleaner 10 will be described. When the fan 280 is driven, air is sucked into the lower body 200 through the suction unit 212 formed at the lower portion of the air cleaner 10. The inhaled air may flow upward and enter the bottom surface of the filter 270 and be discharged through the upper surface.

The air discharged from the filter 270 is sucked into the shroud 260, passes through the fan 280, and passes through the holder 284 and the diffuser 286. The air discharged from the diffuser 286 flows upward through the water reservoir flow passage 231b and the water passage flow passage 241a of the humidifying device 230. Then, the air discharged from the humidifying device 230 flows into the discharge body 320 through the water bottle connection portion 328 of the discharge device 310.

The air may be heated while passing through the first and second heaters 331 and 332 disposed in front and rear portions of the discharge body 320. And, the air may be branched to the first and second discharge flow paths 351 and 355 formed at the front and rear of the first flow guide 341 to flow.

The air flowing through the first discharge flow path 351 is guided by the first flow guide 341 to the discharge hole 325, and the air flowing through the second discharge flow path 355 is the spaced part ( 357), the third discharge flow path 359 may flow while being bent forward. In addition, the air in the third discharge flow path 359 may be guided by the second flow guide 342 to be guided to the discharge hole 325.

15A and 15B are experimental graphs showing the discharge speed in the discharge hole when and without the flow guide inside the discharge body.

15A shows a flow rate change of air discharged from an upper discharge hole and a lower discharge hole when a flow guide is not provided in the discharge body. And, Figure 15b shows the flow rate change of the air discharged from the upper discharge hole and the lower discharge hole when the flow guide 340 according to an embodiment of the present invention is provided in the discharge body 320.

In the graphs of FIGS. 15A and 15B, the origin O of the horizontal axis represents the upper end portion of the discharge body 320, and the larger the value of the horizontal axis represents the position toward the lower portion of the discharge body 320.

The solid lines in FIGS. 15A and 15B represent the upper discharge hole among the plurality of discharge holes 325, for example, the second discharge hole from above based on FIG. 1, and the dotted line is the lower discharge hole, for example, the fourth discharge from above based on FIG. 1 Represents the ball.

In FIG. 15A, the distance from the horizontal axis P1 to P2 represents the length of the upper discharge hole in the vertical direction, and the distance from the horizontal axis P3 to P4 can represent the length of the lower discharge hole in the vertical direction. Likewise, in FIG. 15B, the distance from P1 'to P2' of the horizontal axis represents the vertical length of the upper discharge hole, and the distance from P3 'to P4' of the horizontal axis may represent the vertical length of the lower discharge hole.

15A, when the flow guide 340 is not provided, the discharge speed in the upper discharge hole is large, while the discharge speed in the lower discharge hole is relatively low. In terms of flow rate, the discharge amount from the lower discharge hole corresponds to about 50% of the discharge amount from the upper discharge hole. As such, there is a problem in that the deviation of the discharge amount in the upper discharge hole and the lower discharge hole is large.

On the other hand, referring to Figure 15b, when the flow guide 340 is provided, it can be seen that the discharge speed in the upper discharge hole and the lower discharge hole is almost similar. Therefore, the discharge amount in the upper discharge hole and the lower discharge hole is also formed similarly. Therefore, on the basis of the vertical direction, since air can be discharged evenly from the front of the discharge body, reliability of the product can be improved.
