When the door assembly 200 is pulled forward to open the front surface of the cabinet 100, the air filter assembly 280, humidification filter assembly 300, and water container 270 disposed in the drawer 220 can be pulled forward together. Accordingly, a user can easily access air filter assembly 280, humidification filter assembly 300, and water container 270.

Drawer 220 may be coupled to cabinet 100 such that it can be pulled out of cabinet 100 or pulled back into the cabinet. Accordingly, drawer 220 is sometimes referred to as a "door" or "receiving portion."

The door assembly 200 further includes a rail guide 230 that guides the operation of pulling out the door assembly 200 from the cabinet 100 or returning it into the cabinet 100. Rail guides 230 may be coupled to both sides of the bottom portion of drawer 220.

In other words, the door assembly 200 is provided so as to be movable in the front-rear direction from the cabinet 100. Therefore, the door assembly 200 may be provided so as to be in close contact with the front end portion of the cabinet 100 when the door assembly 200 is pulled into the cabinet.

In particular, the door assembly 200 may include sealing means for sealing the open front surface of the cabinet 100. The sealing means may include a sealing frame 211 and a sealing member 212, which will be described later.

The sealing means can seal a small gap formed between the cabinet 100 and the door assembly 200. Therefore, outside air can intensively flow into the recessed portion 30 or the intake port 225.

A display 108a on which operational information of the air cleaner is displayed is arranged on the front side of the upper panel 105. The display 108a may extend long in the left-right direction, and may be provided on the upper surface of the front portion of a display module 452, which will be described later. Furthermore, the display 108a may be provided with an input unit 108b that allows input by the user.

A plurality of input units 108b may be provided to set the operation mode and operation function of the humidifying air cleaner 10. For example, the input unit 108b can set settings such as "power input unit", "clean intensity", "fast clean", "humidifying clean", "sleep mode", "air sterilization", "mode lighting", and "lock". It may include multiple input units to perform modes (or functions).

Display 108a may be positioned between top panel 105 and door 200. Specifically, a downwardly recessed display groove 108 is formed in the upper portion of the cabinet 100. For example, the top edge of door panel 210 may be spaced forward from the front edge of top panel 105. Further, display groove 108 may be defined as a space formed between door panel 210 and top panel 105.

Therefore, the display 108a is exposed to the outside through the display groove 108, allowing the user to check operating information and operate the input unit 108b.

The top panel 105 is configured flat so that the user can utilize the top panel 105 as a storage space. Products, food, etc. are placed in the storage space. Therefore, it is not easy to arrange a display that the user needs to visually check on the top panel. If the display is placed in the center portion of the top panel, the display may be obstructed by objects or food.

In this embodiment, in order to prevent such a problem, the display 108a may be placed between the front surface of the upper panel 105 and the rear surface of the door. Next, door 200 may be pulled forward to expose the front surface of display 108a to the outside.

3-7, the humidifying air cleaner 10 according to one embodiment of the present invention includes an air filter assembly 280 for filtering air, a humidifying filter assembly 300 for humidifying the air, and a humidifying filter assembly 300 for humidifying the air. It includes a blower fan 480 for generating. A fan motor 485 is coupled to blower fan 480 .

In particular, the cabinet 100 includes a body frame 110 that forms a spatial portion 112 in which the above-mentioned components are arranged.

The main body frame 110 may have a hexahedral shape with open front, rear, and top surfaces. Specifically, the front surface of the main body frame 110 is open, and the open front surface may be covered by the door assembly 200. Furthermore, the rear surface of the main body frame 110 is open, and the open rear surface can be covered by the fan housing 410 and the housing cover 430. Furthermore, the top surface of the main body frame 110 may be open, and the open top surface may be shielded by the electrical unit 450.

The first base 101 can be understood as a component of the main body frame 110.

The two side panels 103 are coupled to both sides of the main body frame 110. In other words, the main body frame 110 may include a first side surface that is one side surface and a second side surface that is the other side surface.

One of the two side panels 103 may be coupled to the first side. Further, the other of the two side panels 103 may be coupled to the second side surface. Therein, the side panel 103 coupled to the first side is referred to as a first side panel 103, and the side panel 103 coupled to the second side is referred to as a second side panel 103.

Top panel 105 is coupled to the upper side of electrical unit 450 and rear panel 107 is coupled to the rear side of housing cover 430.

On the other hand, as mentioned above, at least one of the door panel, the first side panel, the second side panel, and the top panel may be formed of wood.

Therefore, the plurality of panels 103, 105, 107 have a relatively small width and depth, formed by cutting into the inner surface of each panel 103, 105, 107 to prevent deformation of the wood and increase durability. It may include a groove 210b and a plurality of reinforcing frames 215 inserted into the inner surfaces of the panels 103, 105, 107.

The wooden groove 210b may be long along the extending direction of the panel, and may be formed into a plurality of grooves. For example, the wooden groove 210b may be carved into at least one of the plurality of panels 103, 105, 107 in a straight line in the longitudinal direction of the inner surface.

The reinforcing frame 215 may have holes 215a for securing in a configuration that joins multiple panels. For example, a fastening member fastened to the front face 221 of the drawer may be inserted into the hole 215a of the reinforcing frame 215 inserted into the door panel 210. Furthermore, reinforcing frame 215 may be formed of a metal material.

First and second side panels 103 coupled to opposite sides of the body frame 110 may extend in front of a bar 110a that defines a front opening of the body frame 110.

The inner surfaces of each of the first and second side panels 103 located in front of the bar 110a of the main body frame may be in close contact with the outer surface of the ceiling frame 211. Therefore, at least two outer surfaces of the sealing frame 211 can be in close contact with the cabinet 100 to provide a double sealing structure except for the air intake port 225 when the door assembly 200 is pulled into the door assembly 200 .

The bar 110a of the body frame 110 may be formed as a rectangular frame to define a front opening of the body frame 110.

However, in order to avoid interference when the door assembly 200 is pulled out from the cabinet 100 and returned into the cabinet 100, the bar 110a of the main body frame is cut to a predetermined length and the main body frame and door assembly are assembled together. A space may be formed between the two.

Here, the predetermined length may be defined as a length corresponding to a lower gap D1 of the ceiling frame 211, which will be described later. For example, the body frame bar 110a may be provided in a rectangular shape with an open base.

The bar 110a of the main body frame 110 may extend along the front ends of both sides of the main body frame 110. The bar 110a may extend from the lower side of the display module 452 and connect the upper ends of both sides of the main body frame 110.

The lower end portions 110b of the bars 110a of the body frame 110 may be bent from the front ends of both sides of the body frame 110 in directions facing each other. Therefore, the lower end portion 110b of the bar 110a may be cut so as not to interfere with the drawer 220.

In other words, the lower end portions 110b of the bars 110a of the main body frame 110 extending from both sides of the main body frame 110 may be spaced apart from each other by a predetermined length in directions facing each other.

Furthermore, when the door assembly 200 is retracted, the bar 110a of the main body frame and the sealing means are provided in close contact with each other. Therefore, the bar 110a of the main body frame and the sealing means can be formed to correspond to each other.

As a result, the sealing means provided on the rear side of the door panel 210 can come into close contact with the bar 110a and the surfaces of the first and second side panels 103 that extend forward from the bar 110a. .

The sealing means can thus seal the gap between the cabinet 100 and the door assembly 200 in two vertical planes. Therefore, it is possible to more effectively block air from flowing into the gap.

A plurality of reinforcing ribs 111a and 111b may be provided on both sides of the main body frame 110. The reinforcing ribs 111a, 111b include a plurality of first reinforcing ribs 111a extending in the lateral direction and a plurality of second reinforcing ribs 111b extending in a direction intersecting the first reinforcing ribs 111a. For example, the second reinforcing rib 111b may extend in the longitudinal direction.

Furthermore, a discharge channel 111c may be formed on both sides of the main body frame 110 to guide fluid discharged from the electric unit 450 downward. The discharge channel 111c can be understood as a channel formed between the first reinforcing rib 111a and the second reinforcing rib 111b.

Door assembly 200 includes a door panel 210 forming a front appearance and a drawer 220 extending to the rear side of door panel 210.

The width of the door panel 210 in the lateral direction may be set smaller than the distance between the two side panels 103. Thus, the door panel 210 can be inserted between the two side panels 103 to form a flat surface. According to this, the door panel 210 and the two side panels 103 can give the user a sense of unity in appearance. Therefore, the door panel 210 and the two side panels 103 are visually clean and can provide an appearance suitable for recognition as furniture.

The door panel 210 may include a handle groove 210a recessed in an upper portion of the rear surface of the door panel 210 so that the handle groove 210a can be held by a user. Accordingly, by inserting a hand into the display groove 108, the user can pull out the door assembly 200 while pulling the hand through the handle groove 210a.

The door panel 210 may further include a panel frame 218 for guiding coupling with the front surface of the drawer 220.

Panel frame 218 may be coupled to the rear surface of door panel 210. The panel frame 218 may be located inside the ceiling frame 211, which will be described later. For example, the panel frame 218 may be coupled to a panel coupling portion 221a, which will be described later, using a fastening member.

Meanwhile, as described above, the door assembly 200 may further include a sealing means. The sealing means may include a sealing frame 211 and a sealing member 212.

In detail, the sealing frame 211 may be coupled to the rear surface of the door panel 210. The sealing frame 211 may be formed to correspond to the bar 110a of the main body frame 110. For example, the ceiling frame 211 may have a rectangular shape with an open base.

In other words, the lower portion of the ceiling frame 211 may be cut by a predetermined length D1. For example, the lower portion of the sealing frame 211 may form an opening that communicates with the air intake port 225. Accordingly, the lower end portions 211a and 211b of the ceiling frame 211 may be spaced apart by a predetermined length D1 in the direction facing each other.

The lower end portions 211a, 211b of the sealing frame 211 may be located below the air inlet 225 or at both ends of the front portion of the air inlet 225. In particular, the lower end portions 211a, 211b may form an incision space (or a sealing frame gap) communicating with the intake port 225 together with the lower end portion 110b of the bar 110a.

The cutting space (or the sealing frame gap between lower end portion 211a and lower end portion 211b) is in flow communication with a portion 225a of inlet 225. For example, if the lower end portions 211a, 211b and the lower end portion 110b are in close contact with each other, the cutting space (or sealing frame gap) may define both front ends of the inlet 225. Therefore, the air sucked in from the lower end of the door panel 210 can intensively flow into the incision space.

Specifically, the lower end of the sealing frame 211 has a first end portion 211a bent vertically at one lower end, and a second end portion 211b bent vertically at the other lower end. , may also be included. The first end portion 211a and the second end portion 211b may extend horizontally and be separated by a predetermined length D1.

The predetermined length D1 can be referred to as the lower gap D1 of the sealing frame 211.

Since the lower end portions 211a, 211b of the sealing frame 211 are spaced apart from each other by the lower gap D1, the sealing frame gap between the first end portion 211a and the second end portion 211b is equal to A portion 225p may be formed.

Therefore, when the door assembly is pulled into the body frame 110 and the sealing frame 211 and the bar 110a of the body frame contact each other, the lower end portions 211a, 211b of the sealing frame 211 and the lower end portion 110b of the bar 110a of the body frame is cut downward to form a portion 225p of the suction port 255, thereby increasing the air intake cross-sectional area.

On the other hand, the lower gap D1 can be understood as a length corresponding to the width W1 in the left-right direction of the intake port 225, which will be described later.

The length of the outer circumference of the ceiling frame 211 may be smaller than the length of the outer circumference of the door panel 210. The lengths of the outer circumferences of the bars 110a of the ceiling frame 211 and the main body frame may be the same.

Furthermore, the perimeter of the door panel 210 may be smaller than the perimeter of the front surface of the cabinet 100. The top edge of the door panel 210 may be positioned at a height that corresponds to the top edge of the front end of the cabinet 100. Therefore, a recessed space or recessed portion 30 is formed on the lower side of the door panel 210 to guide the inflow of air.

On the other hand, the width D2 of the ceiling frame 211 may be set to a length corresponding to the length of the first and second side panels 103 protruding forward from the bar 110a.

Therefore, the sealing frame 211 closely fits the first and second side panels 103 and the bar 110a of the body frame, thereby reducing unnecessary flow loss and noise. The sealing frame 211 may concentrate air intake into the recessed portion 30 or the air inlet 225.

In other words, when the drawer 220 is pulled into the main body frame 110, the front surface of the bar 110a defining the front opening of the main body frame 110 and the front surface of the sealing frame 211 can come into close contact with each other. At this time, the outer surface of the ceiling frame 211 may be in close contact with the first side panel 103 or the second side panel 103.

In short, at least two of the outer surfaces of the sealing frame 211 can be in intimate contact with at least one of the bar 110a, the first side panel 103, and the second side panel to seal the front opening.

Therefore, a double sealing between the sealing frame 211 and the main body frame 110 is possible, so that the air flow introduced into the intake port 225 can be effectively guided to the air filter assembly 280 without leakage or loss. .

Meanwhile, the sealing frame 211 may form a central groove into which the sealing member 212 is inserted. The central groove may be formed by recessing the central portion of the rear surface of the sealing frame 211. The central groove may extend in the direction in which the sealing frame 211 extends.

The sealing member 212 may be inserted into the rear surface of the sealing frame 211. In other words, the sealing member 212 can be inserted into the central groove of the sealing frame 211.

The sealing member 212 may be formed of a material that can maintain airtightness when the sealing member 212 closely contacts the bar 110a of the main body frame. For example, sealing member 212 may include rubber.

The door panel 210 may further include a cover frame 211c that is in close contact with a filter cover 282a provided at an upper portion of the air filter assembly 280.

The cover frame 211c may be connected to an upper portion forming the upper side of the sealing frame 211. For example, the cover frame 211c may extend downward in a circular manner from the upper side of the sealing frame 211 of the cover frame 211c.

The rear surface of the cover frame 211c may be formed to correspond to the front surface of the filter cover 282a. For example, if the front surface of the filter cover 282a is formed in a round shape, the rear surface of the cover frame 211c may be formed in a corresponding round shape.

Therefore, when the door assembly 200 is pulled into the cabinet 100, the cover frame 211c tightly contacts the filter cover 282a, and the air sucked into the intake port 225 can be guided to pass through the air filter 285 without loss or leakage. can.

A front surface 221 of drawer 220 may be coupled to a rear surface of door panel 210. In other words, the door panel 210 may cover the front opening of the main body frame 110.

The drawer front 221, on the other hand, can be referred to as the drawer door front portion 221 or "first wall." Further, the door panel 210 and the door front section 221 may be collectively referred to as a "door front section."

The door front portion 221 may be provided with a panel coupling portion 221 a coupled to the rear surface of the door panel 210 . For example, the panel coupling portion 221a is recessed rearward from the door front portion 221, and the fastening member is coupled to the panel coupling portion 221a such that the panel coupling portion 221a can be fastened to the panel frame 218 of the door panel 210.

Drawer 220 may further include a connector 221b extending from the rear surface of door front portion 221 to the front surface of air filter pedestal portion 226.

In other words, the connector 221b may be located in the space between the door front portion 221 and the air filter pedestal portion 226 defined as the air intake port 225.

The connector 221b may be located at the lower portion of the rear face of the door front portion 221. Connector 221b may be placed above intake port 225. For example, the connector 221b may extend rearward to have a relatively narrow width to minimize resistance to air flowing from the rear surface of the door front portion 221 to the air intake port 225.

The connector 221b can support the door front portion 221 so that the influence of the position of the air intake port 225 is relatively weak. Therefore, the connector 221b can prevent the door front portion 221 from deforming, thereby improving the durability of the drawer 220.

The drawer 220 includes a door side surface portion 222 extending rearward from both sides of a door front surface portion 221, a door lower surface portion 224 provided below the door side surface portion 222, and a door lower surface portion 224 extending upward from the rear side of the door lower surface portion 224. and an extending door rear portion 223.

Door side portion 222, on the other hand, may be referred to as the side of drawer 220 or the "second wall" of the drawer. Door bottom portion 224 is sometimes referred to as the bottom of drawer 220 or the "third wall" of the drawer. Similarly, door back portion 223 may be referred to as the back wall of drawer 220 or the "fourth wall" of the drawer.

The air intake port 225 may be formed in the door lower surface portion 224.

Therefore, the flow of air flowing into the intake port 225 can be effectively guided.

The slide rail 235 may include a body coupling portion 235a coupled to an inner surface of the body frame 110.

The rail cover 236 is arranged outside the slide rail 235. With the rail cover 236, the slide rail 235 does not have to be exposed to the outside.

Rail guides 230 are provided on both sides of the door assembly 200. The rail guide 230 is coupled to the slide rail 235 and can be pulled out from or into the slide rail 235 and slid back and forth.

Furthermore, the rail guide 230 or slide rail 235 may include stops to limit forward and backward travel distance.

When the drawer 220 is fully extended, the humidification filter assembly 300 may be placed on the flat surface formed by the front opening of the body frame 110.

In other words, the stopper can set the maximum distance that the drawer 220 can be pulled out of the cabinet. The stopper may determine the maximum distance that the drawer 220 can be pulled out of the cabinet depending on the position of the humidification filter assembly 300.

The body frame 110 further includes a lighting bracket 116 to which a lighting device is attached. The lighting bracket 116 may be disposed below the main body frame 110 and may be spaced apart from the first base 101. The lighting bracket 116 may be arranged to face the first base 101.

Body frame 110 further includes a base connecting portion 115 extending upwardly from first base 101 .

It can be seen that the base connecting portion 115 extends downwardly from the rear portion of the lighting bracket 116 towards the first base 101.

The recessed portion 30 may form a space between the first base 101 and the lighting bracket 116. The base connecting portion 115 may shield the rear side of the recessed portion 30.

Furthermore, as mentioned above, the recessed portion 30 can be understood as the space defined by the first base 101, the base connecting portion 115, and the lighting bracket 116.

Body frame 110 further includes a second base 113 that extends rearwardly from base connecting portion 115 and supports drawer 220 . The second base 113 can form a flat surface and support a door underside portion 224 of the drawer 220. First base 101 and second base 113 may be collectively referred to as a "base."

The main body frame 110 may have a stepped configuration upward from the front portion toward the rear side due to the configuration of the first base 101, the base connecting portion 115, and the second base 113. Since the door assembly 200 is supported by the second base 113 and moved in and out of the cabinet 100, the lower part of the door assembly 200 is spaced upwardly from the first base 101, and the space constitutes the recessed part 30. , and can communicate with the intake port 225.

The lighting device includes a lighting PCB 122 having an illumination source 122a and a lighting case 124 coupled to the lighting PCB 122. A plurality of illumination sources 122a may be provided, and the plurality of illumination sources 122a may be arranged in the left-right direction.

The lighting case 124 includes a partition rib 124b that partitions the interior space of the lighting case 124 into a plurality of spaces 124a, and the illumination source 122a may be arranged in each of the plurality of spaces 124a. Illumination source 122a may be coupled to one surface of illumination PCB 122 and configured to emit light downwardly. For example, the illumination source 122a may be attached to the bottom or front of the illumination PCB 122.

A reflective plate 120 may be provided on the upper surface of the first base 101. The reflective plate 120 may be disposed below the plurality of illumination sources 122a and provided to gently reflect or diffuse the light emitted from the illumination sources 122a. The illumination source 122a is arranged above the reflection plate 120 and irradiates light downward toward the reflection plate 120. A recessed portion 30 may be formed between the illumination source and the reflective plate 120.

The humidifying air cleaner 1 can provide gentle light to the region where the recessed portion 30 or the air intake port 225 is located, depending on the light emitted by the illumination source 122a. The lighting device is therefore sometimes also referred to as mood lighting.

A human body detection sensor may be installed on the front surface of the lighting case 124. The human body detection sensor can detect a human body approaching toward the door panel 210. For example, when the human body detection sensor detects a human body approaching the humidifying air cleaner 1, the lighting device can operate to adjust the brightness of the illumination source 122a.

FIG. 8 is a diagram showing a state in which an air filter and a humidifying filter are arranged on a door according to an embodiment of the present invention, and FIG. FIG. 10 is a perspective view showing the configuration of the door according to an embodiment of the present invention, and FIG. 11 is a diagram showing a door configuration according to an embodiment of the present invention. 12 is a plan view showing the structure of a door according to an embodiment of the present invention, and FIG. 13 is a diagram showing the internal structure of a cabinet according to an embodiment of the present invention.

8-13, door assembly 200 includes a drawer 220 coupled to the rear side of door panel 210, as described above.

The drawer 220 may be provided to be pulled forward from the cabinet and pulled back into the cabinet. In other words, the drawer 220 may be provided with a similar configuration to a furniture drawer.

Drawer 220 may include an air filter assembly 280, a humidification filter assembly 300, a water container 270, and an aquarium 260.

As described above, the drawer 220 includes a front surface 221, both side surfaces 222 extending rearward from both ends of the front surface 221, and extending so as to connect to the lower end portions of both sides 222. A bottom surface 224 that forms a space 225 spaced apart in the direction, and a rear surface 223 that connects the rear end of the bottom surface 224 and the rear ends of both side surfaces 222 are provided.

Both side surfaces 222 may extend so as to be inclined so that the height decreases toward the rear side. The rear ends of both side surfaces 222 and the rear surface 223 may extend upward to be lower than the height of the front surface 221.

As mentioned above, the drawer bottom surface 224 that forms the base surface for the lower portion of the drawer 220 may be referred to as the door underside portion 224.

The drawer front 221 may also be referred to as the door front portion 221.

An intake port 225 through which air is sucked is formed in the lower surface portion 224 of the door. The air inlet 225 may be located on the rear side of the door front portion 221. For example, the air inlet 225 may be formed through at least a portion of the door underside portion 224.

The width W1 of the intake port 225 in the left-right direction may be larger than the width W2 in the front-rear direction. The width W1 in the left-right direction may have a size corresponding to the width of the air filter assembly 280 in the lateral direction.

Air outside the humidifying air cleaner 10 may be drawn into the air intake port 225 via the recessed portion 30. The inhaled air then flows upward and is purified while passing through air filter 285.

Door underside portion 224 includes an air filter pedestal portion 226 on which an air filter assembly 280 is seated.

Air filter pedestal portion 226 is sometimes referred to as an air filter pedestal surface. Inlet 225 may be defined as an opening formed from the front end of air filter pedestal portion 226 to front face 221 of drawer 220.

The air filter pedestal portion 226 can be placed on the rear side of the air intake port 225. Because the bottom surface of air filter assembly 280 seats on air filter pedestal portion 226, air filter pedestal portion 226 may be formed as a flat surface that corresponds to the bottom surface of air filter assembly 280.

The air filter pedestal portion 226 may be provided with jaws 226a for supporting the air filter assembly 280 from the rear side.

Jaw 226a may project upwardly from the rear edge of air filter pedestal portion 226. Jaw 226a is sometimes referred to as a "rear support jaw."

The lower door portion 224 further includes a pedestal surface 227 on which an aquarium 260 is placed. The pedestal surface on which the aquarium 260 is placed may be referred to as the aquarium pedestal portion 227 or the aquarium pedestal surface.

Furthermore, the air filter pedestal portion 226 and the water tank pedestal portion 227 may be collectively referred to as a “pedestal portion” or a “pedestal surface”.

The water tank pedestal portion 227 may be formed at a lower position than the air filter pedestal portion 226. For example, the bottom surface 224 of the drawer 220 may be formed with an aquarium pedestal portion 227 that is recessed downward from the air filter pedestal portion 226 toward the rear side of the air filter pedestal portion 226 . Furthermore, the bottom surface of the aquarium pedestal portion 227 may be formed with a flat design.

Therefore, when the aquarium 260 is seated on the aquarium pedestal portion 227, the aquarium does not impede the air flow because the aquarium 260 is located at a lower position than the air filter assembly 280, and the stored water flows into the air flow path. No splashing.

Meanwhile, the jaws 226a can divide the interior space of the drawer 220 into an air purification space where the air filter assembly 280 is installed and an air humidification space where the water tank 260 is installed.

In the air humidification space, water supplied from the water container 270 is stored in the water storage portions 229a and 229b, and the stored water is pumped up by the rotation of the humidification filter assembly 300 to perform a humidification process to humidify the air.

If the water flowing through the humidification process scatters or flows into the air-cleaning space, there is a possibility that the indoor space in which the humidifying air-purifier 1 is installed will be contaminated through the air intake port 225. Additionally, the air purification performance of air filter assembly 280 may be reduced.

Therefore, the jaws 226a can perform a waterproof function to prevent water from scattering from the air humidification space to the air purification space. In other words, the jaw 226a may extend upward to be higher than the aquarium pedestal portion 227 and the air filter pedestal portion 226.

Air filter pedestal portion 226 may be located higher than aquarium pedestal portion 227. The upper end of the jaw 226a may be located higher than the bottom surface of the aquarium pedestal portion 227 by a predetermined height H4.

In other words, the jaw 226a may extend upward from the aquarium pedestal portion 227 by a predetermined height H4.

Here, the predetermined height H4 may be set larger than the maximum height of the water tank 260. For example, the maximum height of the aquarium 260 may be defined as the distance from the bottom of the aquarium 260, which defines the water storage portions 229a, 229b, to the top of the water container support portion 261, which forms the appearance of the aquarium 260.

In other words, the predetermined height H4 may be set to be greater than the vertical distance from the bottom end to the top end of the water tank 260. Therefore, the jaws 226a can prevent water from flowing into the air purification space from the water storage portion located in the water tank pedestal portion 227.

The air intake port 225, the air filter pedestal portion 226, and the aquarium pedestal portion 227 may be sequentially aligned in the front-back direction within the drawer 220. Therefore, the air sucked into the intake port 225 flows backward and passes through the air filter 285 and the humidifying filter 330, so that fluidity can be improved.

Moreover, the air flowing into the lower end of the door panel 210 due to the air inlet 225 formed in the front region of the bottom surface of the drawer 220 can flow upwardly through the air inlet 225 .

The air passing through the intake port 225 passes through the air filter assembly 280 seated on the air filter pedestal portion 226, and the humidification filter assembly 300 is seated on the aquarium pedestal portion 227, thus allowing air purification and air humidification. .

Here, since the air filter assembly 280 and the humidifying filter assembly 300 are inserted from the upper side of the drawer 220, the region (or area) into which the air flows is relatively perpendicular to the air filter pedestal portion 226 and the aquarium pedestal portion 227. It may be formed in the direction or in the longitudinal direction.

In other words, the flow path of the air directed upwardly through the inlet 225 may be laterally bent so that the air passes through the air filter 285 and humidification filter 330.

Therefore, the humidifying air cleaner 1 according to the embodiment of the present invention using the air flow path described above can be installed such that the upper end of the air filter 285 and/or the humidifying filter 330 is inclined more forward than the lower end. Therefore, the air purification effect and air humidification effect can be improved.

In other words, air filter assembly 280 may be inserted into drawer 220 at an angle. Therefore, the air intake area in the air flow path can be maximized.

Specifically, the air filter assembly 280 may have a lower end located at the rear end of the air inlet 225 and an upper end located at the upper end of the door front portion 221.

At this time, the length from the lower end to the upper end of the air filter assembly 280 is the length from the upper end of the door front portion 221 to the front end of the air intake port 225 and/or the length from the front end of the air intake port 225 to the air filter assembly. It may be longer than the length to the lower end of 280.

The length H3 from the lower end to the upper end of the air filter assembly 280 is at least the first length H1 from the front end of the air inlet 225 to the lower end and from the front end of the air inlet 225 to the upper end of the door front section. may be formed to be longer than at least one of the second length H2.

Below, an installation structure for maximizing the intake area and simply and stably fixing and supporting the air filter 285 according to the position and shape of the air intake port 225 will be described in detail.

Door side portion 222 includes filter guides 225a for supporting both side portions of air filter assembly 280.

The filter guide 225a may extend obliquely upward from both ends of the air filter pedestal portion 226. The filter guide 225a may extend forward from the lower portion toward the upper portion by being inclined at a predetermined angle α1.

In other words, the filter guide 225a may extend diagonally rearward toward the door lower surface portion 224. Accordingly, when the air filter assembly 280 is seated on the air filter pedestal portion 226, the air filter assembly 280 may be arranged to tilt diagonally forward.

Therefore, the user can easily lift the air filter assembly 280 upward. Accordingly, filter guide 225a can facilitate separation of air filter assembly 280 from drawer 220.

Furthermore, the door side portion 222 further includes filter support portions 225b that extend on both sides of the filter guide 225a and support both ends of the front surface of the air filter assembly 280.

The filter support portion 225b may extend a predetermined length from the front portion of the filter guide 225a in the left-right direction (or in both directions). The predetermined length may be set to a length that does not interfere with the air filter 285 of the air filter assembly 280.

Filter support portion 225b may support a portion of the front surface of air filter assembly 280. In other words, the filter support portion 225b can function as a "front support jaw" that supports the air filter assembly 280 so that the air filter assembly 280 does not fall forward in the inclined arrangement.

The filter support portion 225b may also extend forward from the lower end toward the upper end at a predetermined angle α1. In other words, the oblique side of the filter support portion 225b, which will be described later, may extend from the upper end toward the lower end so as to be inclined backward by a predetermined angle α1.

In other words, the angle between the filter support portion 225b and the door front portion 221 forms a predetermined angle α1. The predetermined angle α1 may form an acute angle, for example in the range from 5 to 45 degrees.

Therefore, the front, both sides, and a portion of the upper end of both sides of the air filter assembly 280 are supported by the filter guide 225a and the filter support portion 225b, so that the air filter assembly 280 is tilted forward and disposed. The air filter assembly 280 can be stably fixed even if the air filter assembly 280 is fixed.

Meanwhile, the length of the surface of the filter support portion 225b that supports the front surface of the air filter assembly 280 may be formed to correspond to the length of the front surface of the air filter assembly 280 in the vertical direction. For example, the vertical length of air filter 285 may be equal to the length of the side surface supported by filter support portion 225b.

Specifically, the filter support portion 225b has a lower end formed at the front end of the air filter pedestal portion 226 and an upper end formed at the upper end of the door front portion 221. In other words, the filter support portion 225b may extend from the front end of the air filter pedestal portion 226 to the upper end of the door front portion 221 so as to be inclined forward. Therefore, the intake port 225 may be located at the lower end of the filter support portion 225b.

Here, the width H1 of the air intake port 225 may be defined as the distance between the front end of the air filter pedestal portion 226 and the rear surface of the door front portion 221. In other words, the length H1 of the base of the filter support portion 225b may be defined as the width H1 of the intake port 225. The length of the base of filter support portion 225b may be referred to as a first length H1.

Furthermore, the length H2 of the edge where the filter support portion 225b and the door front portion 221 are in contact with each other is such that the length H2 of the edge where the filter support portion 225b and the door front portion 221 are in contact with each other is such that the edge portion is spaced horizontally forward from the lower end of the filter support portion 225b from the point of the corresponding door front portion 221. It can be defined as the length to the upper end of the door front portion 221. In this case, the length of the edge of the filter support portion 225b may be referred to as a second length H2.

Further, the length H3 of the oblique side of the filter support portion 225b may be defined as the length H3 from the front end of the air filter pedestal portion 226 to the upper end of the door front portion 221. In this case, the length of the oblique side of the filter support portion 225b may be referred to as a third length H3.

Filter support portion 225b may support the front surface of air filter assembly 280 from the front side. In particular, filter support portion 225b may support filter case 281 of air filter assembly 280. Specifically, the filter support portion 225b may be supported in contact with a front end portion of a first case portion 281a, which will be described later.

The front end portion of the first case portion 281a may be formed to have a length H3 corresponding to the oblique side of the filter support portion 225b. Therefore, the front surface of the air filter 285 may be formed to have a length H3 corresponding to the oblique side of the filter support portion 225b.

The third length H3 may be set longer than the second length H2 and the first length H1.

In other words, the oblique side of the filter support portion 225b extends longer than the edge of the filter support portion 225b. Accordingly, the air filter 285 may extend longer than the vertical edges of the filter support portion 225b.

Furthermore, the edge of the filter support portion 225b may extend longer than the width of the air inlet 225.

Accordingly, the air filter 285 can be inserted diagonally into the drawer 220 to optimize the air intake area.

Further, by allowing the user to leave the bottom end of the separated air filter assembly 280 of the door top portion 228 with the bottom end of the separated air filter assembly 280 inserted into the door top portion 228. , the air filter assembly 280 slides downward along the guide of the filter support portion 225b due to gravity. As a result, air filter assembly 280 can be easily installed.

The side surface of the filter support portion 225b may be formed into a triangular shape. For example, the base of filter support portion 225b may be perpendicular to the hypotenuse of filter support portion 225b. In other words, the side surfaces of the filter support portion 225b may form a right triangle. In this case, the length H2 of the oblique side of the filter support portion 225b may be derived from a known formula.

The filter guide 225a is provided with a protruding guide rib 225c for guiding and supporting the rear side of the air filter assembly 280.

The guide ribs 225c may be arranged at the rear end portions on both sides of the air filter pedestal portion 226. The guide rib 225c may extend upward from the air filter pedestal portion 226, and may have an upper portion bent rearward.

Guide rib 225c includes a first portion 225d extending upward from jaw 226a, and a second portion 225e bent rearward from an upper portion of first portion 225d.

The air filter case 281 is provided with a mounting protrusion 280a that contacts the guide rib 225c. The mounting protrusion 280a may protrude rearward from the air filter case 281. When the air filter assembly 280 is attached to the air filter pedestal portion 226, the attachment protrusion 280a contacts the front surface of the guide rib 225c.

As the air filter assembly 280 moves downward toward the air filter pedestal portion 226, the mounting protrusion 280a passes through the front side of the second portions 225e, 225d and toward the front side of the first portion 225d.

At this time, since the second portion 225e is bent from the first portion 225d, the mounting protrusion 280a easily moves downward without interfering with the second portion 225e, and the mounting protrusion 280a is bent from the first portion 225d. 225d, installation of air filter assembly 280 may be completed. The contact between the mounting protrusion 280a and the guide rib 225c can prevent the air filter assembly 280 from shaking.

The door side portion 222 includes an inner plate 222a extending rearward from a filter guide 225a, an outer plate 222b spaced apart from the outer surface of the inner plate 222a, and a plurality of reinforcing ribs 222c extending from the inner plate 222a to the outer plate 222b. and further includes.

The inner plate 222a forms the inner surface of the door side portion 222, and the outer plate 222b is arranged shorter than the inner plate 222a. Specifically, an upper portion of outer plate 222b may be connected to an upper portion of inner plate 222a, and a lower portion of outer plate 222b may be disposed above the lower portion of inner plate 222a.

Therefore, a guide installation space 222d that is recessed toward the inner plate 222a is formed below the outer plate 222b. A rail guide 230 may be arranged in the guide installation space 222d. A rear portion of rail guide 230 may be coupled to rear portions of inner plate 222a and outer plate 222b.

The rail guide 230 may be movably coupled to a slide rail 235 provided on the main body frame 110.

On the other hand, rail guide 230 and slide rail 235 may be referred to as a rail assembly.

Furthermore, the rail guide 230 or the slide rail 235 may include a stopper for limiting the distance by which the drawer 220 is moved in and out of the cabinet 100 in the front-back direction.

As another example, the body frame 110 may further include rail retaining jaws 235b to forcefully limit the distance that the door assembly 200 can be pulled out of the cabinet.

The rail retaining jaws 235b may be spaced forward from the front end of the rail cover 236. For example, the rail retaining jaws 235b may be located at the lower end portion 110b of the bar 110a of the body frame. More specifically, the rail holding jaws 235b may protrude upward from the lower end portion 110b of the main body frame 110.

Slide rail 235 or rail guide 230 may be pulled forward until slide rail 235 or rail guide 230 contacts rail retaining jaws 235b. Since the rail holding jaws 235b protrude perpendicularly to the traveling direction of the slide rail 235 or the rail guide 230, the slide rail 235 or the rail guide 230 is held by the rail holding jaws 235b. Accordingly, the rail retaining jaws 235b can limit the distance that the door assembly 200 can be pulled out of the cabinet.

Rail retaining jaws 235b or stops (not shown) may define a maximum distance that door assembly 200 can be extended out of the cabinet. In particular, the maximum distance that the door assembly 200 can be pulled out may be set such that the humidification filter assembly 300 is located on a flat surface formed by the front end of the body frame 110.

In other words, when the door assembly 200 is completely pulled out, the front surface of the humidifying filter case 310 and the front surface of the bar 110a of the main body frame may be located on a flat surface.

Therefore, when the door assembly 200 is pulled out, the configurations of the humidifying air cleaner 1 that need to be managed, ie, the air filter assembly 280, the water container 270, and the humidifying filter assembly 300, can be pulled out together.

Further, since the humidifying filter assembly 300 is located at a position corresponding to the front opening of the main body frame 110, the user can pull out the configuration that needs to be managed at once toward the operable space. In other words, accessibility to management components can be improved.

Furthermore, when the door assembly 200 is pulled out, the humidifying filter assembly 300 is located at the front opening of the main body frame 110 or the cabinet 100, thereby preventing the internal space 112 of the main body frame from being exposed to the field of view.

Therefore, even if the door assembly 200 is pulled out to the maximum extent, the user can be prevented from accessing the internal structure of the cabinet 100. Therefore, product safety can be improved.

Even when the door assembly 200 is pulled out to the maximum extent, the components provided in the internal space 112 are not exposed to the user, so the appearance of the humidifying air cleaner 1 can be maintained. This allows for product upgrades as it can satisfy the emotional aspects of the users.

A through hole 223b in which a sterilizer 269 is disposed is formed in the rear surface portion 223 of the door. For example, the sterilizer 269 may be placed inside the through hole 223b, or may be placed on the rear side of the through hole 223b. The light emitted from the sterilizer 269 is transmitted to the water tank 260 through the through hole 223b, and can sterilize water.

Door assembly 200 further includes a door top portion 228 that forms a front top surface of drawer 220. The door top portion 228 forms the top surface of the filter guide 225a and may be provided on both sides of the drawer 220.

A mounting groove 228a is formed in the door upper surface portion 228 and is recessed downward, into which an air filter assembly 280 is mounted. The air filter case 281 of the air filter assembly 280 is provided with an insertion protrusion 280b that is inserted into the mounting groove 228a.

Specifically, the air filter case 281 includes a first case portion 281a that slides along the filter guide 225a and extends obliquely in the vertical direction, and a first case portion 281a that is provided above the first case portion 281a and that extends in the left-right direction. A second case portion 281b is provided. The first case portion 281a forms a side surface portion of the air filter case 281, and the second case portion 281b forms a top surface portion of the air filter case 281.

The insertion protrusion 280b may be provided on the second case portion 281b and protrude downward from the bottom surface of the second case portion 281b. When the second case portion 281b is seated on the top surface of the filter guide 225a, the insertion protrusion 280b can be inserted into the mounting groove 228a.

A water container 270 is arranged above the water tank 260. The water container 270 includes a water container body that stores water, and a water container lid 271 that is removably connected to the top of the water container body. The user can separate the water container cover to refill the water within the water container body.

When the water container 270 is placed in the water tank 260, the valve device 276 of the water container 270 is opened and the water stored in the water container 270 can flow into the first water storage portion 229a.

Humidification filter assembly 300 may be attached to aquarium 260. The humidifying filter assembly 300 may be placed on the rear side of the water container 270, and the lower portion of the humidifying filter assembly 300 may be placed to be immersed in the second water storage portion 229b.

FIG. 14 is an exploded view showing the configuration of an air filter assembly according to an embodiment of the present invention, and FIG. 15 is a cross-sectional view showing the flow of air within the humidifying air cleaner according to an embodiment of the present invention.

14 and 15, the air filter assembly 280 includes an air filter case 281 having a first case portion 281a and a second case portion 281b, a filter mounting portion 283 coupled to the air filter case 281, and a filter mounting portion 283 coupled to the air filter case 281. An air filter 285 coupled to mounting portion 283 may also be included.

Below, for convenience of explanation, air filter case 281 may be referred to as filter case 281.

Filter case 281 may be formed into a rectangular shape with sloped sides. For example, the side surface of the filter case 281 may be formed into a parallelogram.

The side surface of the filter case 281 can be understood as a first case part 281a, and the top surface of the filter case 281 can be understood as a second case part 281b.

The second case portion 281b includes a filter guide pedestal portion 282b provided at the upper portion of the first case portion 281a, and a filter cover 282a coupled to the upper surface of the filter guide pedestal portion 282b. The filter cover 282a may be provided in a plate shape with a flat surface.

The filter case 281 may be configured to have an open front and rear surface and a shape corresponding to the air filter pedestal portion 226 and the filter guide 225a. For example, the filter case 281 may have a hexahedral shape that is open in the front-rear direction.

The lower surface of filter case 281 may be seated on air filter pedestal portion 226 and may have a shape corresponding to air filter pedestal portion 226 . For example, the lower surface of filter case 281 may be formed as a flat surface.

Accordingly, air filter assembly 280 may be removed from drawer 220 and placed to stand on flat ground. Therefore, the manageability of the air filter assembly can be improved.

Meanwhile, when the lower surface of the filter case 281 contacts the ground and the air filter assembly 280 stands up, the upper surface of the filter case 281 may be formed to be sloped upward toward the front.

Specifically, an imaginary straight line drawn in the direction in which the edge formed by the top and side surfaces of the filter case 281 extends can be defined as the first parallel line P1. An imaginary straight line drawn parallel to the first parallel line P1 from the front end of the edge formed by the lower surface and side surface of the filter case 281 can be defined as a second parallel line P2.

The first parallel line P1 and the second parallel line P2 are parallel to each other.

Furthermore, an imaginary straight line drawn in the direction in which the edge formed by the lower surface and side surface of the filter case 281 extends can be defined as an inclined line P3.

The slope line P3 has a predetermined slope angle β from the second parallel line P2. For example, the inclination angle β may be set to an acute angle.

In other words, the upper surface of filter case 281 may extend downward with respect to the lower surface of filter case 281 so as to have an inclination angle β. Specifically, the upper surface of the filter case 281 may be formed as an inclined surface that is inclined downward by an inclination angle β toward the rear end than the lower surface of the filter case 281.

Furthermore, the lower surface of filter case 281 may extend upward with respect to the upper surface of filter case 281 so as to have an inclination angle β. Specifically, the lower surface of the filter case 281 may be formed as an inclined surface that is more inclined upward toward the rear end than the upper surface of the filter case 281.

In other words, the extension lines of the upper and lower surfaces of the filter case 281 are not parallel to each other and can intersect at any virtual point.

Furthermore, the air filter pedestal portion 226 may form a top surface that slopes upwardly toward the rear end. Here, the inclination angle β formed by the upper surface of the air filter pedestal portion 226 may be the same as the inclination angle β of the filter case 281 described above.

Accordingly, the lower end portion of the air filter assembly 280 may be formed to have a "V"-shaped longitudinal section, for example. The side surfaces where the filter support portion 225b and the air filter pedestal portion 226 are connected to each other may form a “V” shape. Therefore, the lower end portion of the air filter assembly 280 can fit into the edge where the filter support portion 225b and the air filter pedestal portion 226 are connected to each other.

As a result, when the user places the air filter assembly 280 on the door top portion 228 and leaves the air filter assembly 280 in place, the air filter assembly 280 slides downward due to gravity, causing the slope of the pedestal portion 226 and the filter support portion 225b to slide downward. Since it fits on the top surface, installation can be completed easily. In other words, user convenience can be improved.

When the air filter assembly 300 is seated on the air filter pedestal portion 226, the lower edge of the filter case 281 is inclined by the angle of inclination β. Accordingly, the upper surface of the filter case 281, ie the second case portion 281b, may be horizontally arranged and seated on the door upper surface portion 228.

As a result, the air filter assembly 280 and the drawer 220 according to embodiments of the present invention can maximize the flow cross-sectional area of the air drawn into the air filter 285, allowing the user to easily install the filter assembly 280. It has the advantage that it can be separated or installed.

Meanwhile, both side surfaces of the filter case 281, that is, the first case portion 281a, may extend forward from the bottom surface toward the top portion. In other words, the first case portion 281a may be formed to correspond to the filter guide 225a.

The second case portion 281b extends to join the upper portion of the first case portion 281a, and the upper surface of the second case portion 281b is larger than the distance between the first case portions 281a on both sides. extend for a long time. Therefore, both side portions of the second case portion 281b may protrude outward from the first case portion 281a and be supported by the door top portion 228. The insertion projections 280b may be provided on both sides of the bottom surface of the second case portion 281b.

Filter case 281 may further include a handle 282c that can be grasped by a user. The handle 282c may include a groove in the upper portion of the filter case 281. For example, the handle 282c may be recessed so as to be inclined downward from the rear upper portion of the filter case 281. Therefore, the user's hand can easily insert the filter case 281 from the rear side.

A user can grasp the handle 282c along with the filter cover 282a by inserting a hand into the handle 282c. As a result, the user has the advantage of easily separating or installing the air filter assembly 280 in the inclined vertical direction by grasping the handle 282c.

The filter mounting portion 283 may extend in the vertical direction with a length corresponding to the oblique side of the filter support portion 225b.

Filter mounting portion 283 may include multiple frames 283a, 283b. For example, the filter mounting portion 283 may include an outer frame 283a corresponding to the open front end portion of the filter case 282, and an inner frame 283b extending vertically or in both directions from the outer frame. The inner frame 283b may be formed to connect the opposing outer frames 283a. The frame may be formed from a material that has relatively high ductility.

Therefore, the frame can be bent by applying pressure by the user. Thereby, the user can easily separate the filter mounting portion 283 from the filter case 281 via the filter mounting portion 283 that is bent by pulling the mounting rib 286, which will be described later.

The air filter 285 may be coupled and stably fixed by the filter mounting portion 283. For example, the air filter 285 is fitted into the frames 283a and 283b, thereby disposed in a space formed by the frames, and purifies the air sucked in.

The air filter 285 includes at least one of a pre-filter for filtering substances having relatively large particles, a HEPA filter for filtering substances having relatively small particles, and a deodorizing filter for removing odors. It may include one.

Filter mounting portion 283 and air filter 285 may be located at the open front end portion of filter case 282. Specifically, the filter mounting portion 283 can fit into the filter case 281. To this end, the filter mounting portion 283 may include an upper fixing protrusion 287 and a lower fixing protrusion 288.

A plurality of upper fixing protrusions 287 may be formed at the upper end portion of the filter mounting portion 283. For example, the upper fixing protrusion 287 may protrude upward from the upper portion of the filter mounting portion 283.

A plurality of lower fixing protrusions 288 may be formed at the lower end portion of the filter mounting portion 283. For example, the lower fixing protrusion 288 may protrude downward from the lower portion of the filter mounting portion 283.

The filter case 281 may include an upper fixing groove 284a into which the upper fixing protrusion 287 is inserted, and a lower fixing groove 284b into which the lower fixing protrusion 288 is inserted.

The upper fixing groove 284a may be formed as an inwardly recessed groove on the upper end surface of the filter case 282. The upper fixing grooves 284a may be formed to correspond to the number and position of the upper fixing protrusions 287. Therefore, the upper fixing protrusion 287 may be inserted into the upper fixing groove 284a and fitted into the upper fixing groove 284a.

The lower fixing groove 284b may be formed as a groove recessed inward on the lower surface of the filter case 281. The lower fixing grooves 284b may correspond to the number and position of the lower fixing protrusions 288. Therefore, the lower fixing protrusion 288 may be inserted into the lower fixing groove 284b and fitted into the lower fixing groove 284b.

Filter mounting portion 283 may further include attachment ribs 286 that can be gripped by a user. The mounting rib 286 may protrude forward from the front surface of the filter mounting portion 283. For example, the mounting rib 286 may be formed to protrude forward from the front surface of the inner frame of the filter mounting portion 283.

Furthermore, the mounting ribs 286 may be provided symmetrically with respect to the plurality of inner frame front surfaces. In other words, a pair of mounting ribs 286 may be provided. Therefore, the user can easily attach the filter mounting portion 283 to the filter case 281 or separate the filter mounting portion 283 from the filter case 281 by grasping the mounting ribs 286 on the front surface.

Because the mounting ribs 286 extend forward from the front end face of the inner frame, the mounting ribs 286 do not block along the direction of flow of air entering through the recessed portion 30 and passing through the air filter 285. Advantageously, the air passes through the entire intake surface of the air filter 285.

Furthermore, the user can easily manage the air filter 285 because the user can grasp the mounting rib 286 so that the upper fixing protrusion 287 and the lower fixing protrusion 288 are easily inserted into the upper fixing groove 284a and the lower fixing groove 284b. can.

With reference to FIG. 15, the flow of air within the humidifying air cleaner according to the embodiment of the present invention will be briefly described.

When the blower fan 480 is activated, air outside the air cleaner can be sucked into the air intake port 225 through the recessed portion 30 . Air sucked in through the intake port 225 flows upward and into the drawer 220.

The air then passes through air filter assembly 280. When the air filter assembly 280 is seated on the air filter pedestal portion 226, the air filter assembly 280 is tilted forward, so that air can uniformly pass through the filter surface of the air filter assembly 280.

Air filtered by air filter assembly 280 may flow rearward and pass through humidification filter assembly 300. The air is humidified while passing through humidification filter assembly 300 and the humidified air may pass through blower fan 480.

Air filter assembly 280, aquarium 260, and humidification filter assembly 300 are arranged rearward in order from the front portion of drawer 220, thereby facilitating filtering and humidification of the air.

Air may be drawn in axially of the blower fan 480 and exhausted radially. The air that has passed through the blower fan 480 may flow upward and be exhausted to the outside through the exhaust portion 109. In other words, air is sucked into the front lower part of the humidifying air cleaner 10 and discharged to the rear upper part, so that flow resistance is reduced and air blowing performance can be improved.
