Since the steam housing 2310 stores water heated by the steam heater 2320, it is preferable to be formed of a heat-resistant material. In this embodiment, the steam housing 2310 is formed of SPS material. The steam housing 2310 includes an upper steam housing 2340 and a lower steam housing 2350 .

The upper steam housing 2340 has an open lower side and is concave from the lower side to the upper side. The lower steam housing 2350 has an open upper side, and is concave from the lower side to the lower side.

In this embodiment, the water pipe 2314 is disposed in the lower steam housing 2350 , and the steam discharge part 2316 and the air suction part 2318 are disposed in the upper steam housing 2340 .

The water pipe 2314 is disposed lower than the chamber housing pipe 2214 of the water supply assembly 2200 . The water in the chamber housing pipe 2214 flows into the water pipe 2314 by its own weight through the difference in height between the water pipe 2314 and the chamber housing pipe 2214 .

In this embodiment, the first water level sensor 2360 , the second water level sensor 2370 , and the thermistor 2380 are disposed in the upper steam housing 2340 . To this end, the upper steam housing 2340 includes a first water level sensor installation unit 2342 in which the first water level sensor 2360 is installed, and a second water level sensor installation unit in which the second water level sensor 2370 is installed ( 2344) and the thermistor installation part 2346 to which the thermistor 2380 is installed are formed.

The air intake portion 2318 and the steam discharge portion 2316 formed in the upper steam housing 2340 have different heights. The steam discharge unit 2316 and the air suction unit 2318 form a height difference SH, and the steam discharge unit 2316 is disposed higher than the air suction unit 2318 by the height difference SH.

This is to allow the steam inside the upper steam housing 2340 to easily gather to the steam discharge unit 2316 . When the steam discharging unit 2316 is formed to be higher than the air suction unit 2318 , steam having a low density may be collected under the steam discharging unit 2316 .

In this embodiment, since the first water level sensor 2360 detects the low water level of the steam generator 2300 , it is installed on the main surface of the air intake 2318 . Since the second water level sensor 2370 detects the high level of the steam generator 2300 , it is installed around the steam discharge unit 2316 .

Since the first water level sensor 2360 and the second water level sensor 2370 form a height difference, the electrode lengths of the first water level sensor 2360 and the second water level sensor 2370 can be minimized.

The first water level sensor 2360 includes a 1-1 water level detection unit 2361 and a 1-2 water level detection unit 2362 . Lower ends of the 1-1 water level sensing unit 2361 and the 1-2 water level sensing unit 2362 are disposed at the same height. In the present embodiment, the 1-1 water level sensing unit 2361 and the 1-2 water level sensing unit 2362 are electrodes. When water comes into contact with the 1-1 water level detection unit 2361 and the 1-2 water level detection unit 2362, the control unit detects it.

In the present embodiment, the lower ends of the 1-1 water level sensing unit 2361 and the 1-2 water level sensing unit 2362 are the lowest water level WL for driving the steam generator 2300 . If the water level is lower than the lower ends 2361a and 2362a of the 1-1 water level sensing unit 2361 and the 1-2 water level sensing unit 2362, the steam heater 2320 may be damaged. Therefore, when the water level is lower than that of the lower ends 2361a and 2362a of the 1-1 water level sensing unit 2361 and the 1-2 water level sensing unit 2362, the power supplied to the steam heater 2320 is cut off.

In the present embodiment, the second water level sensor 2370 uses an electrode that detects the contact with water. The lower end 2370a of the second water level sensor 2370 senses the highest water level WH of the steam generator 2300 . When the water level of the steam generator 2300 is higher than the lower end 2370a of the second water level sensor 2370 , water may boil and overflow by the operation of the steam heater 2320 . When the water level touches the lower end 2370a of the second water level sensor 2370, the operation of the steam heater 2320 is stopped.

The highest water level WH is a height in consideration of the inclination of the indoor unit. That is, when the indoor unit is inclined in either direction, the water level inside the steam housing 2310 may be higher in either direction. In the present embodiment, when the indoor unit is tilted by 3 degrees to either side and the steam generator 2300 is maximally operated, a height at which water does not overflow out of the steam housing 2310 is set as the highest water level WH.

When the highest water level WH is reached, the operation of the steam heater 2320 may be stopped and the drain assembly 2700 may be operated to drain the water inside the steam housing 2310 .

The appropriate water level of the steam generator 2300 is lower than the lower end 2370a of the second water level sensor 2370, and the 1-1 water level detecting unit 2361 and the 1-2 water level detecting unit 2362 lower end ( 2361a) (2362a) should be formed higher. In this embodiment, this is defined as an appropriate water level.

The lower end 2380a of the thermistor 2380 is disposed within the appropriate water level. The thermistor 2380 detects when the internal temperature of the steam generator 2300 rises above a set value, and stops the operation of the steam heater 2320 .

The larger the area of the air suction part 2318 is, the more advantageous it is. In this embodiment, the air intake portion 2318 is formed wider than the steam discharge portion 2316 .

The water pipe 2314 communicates with the inside of the steam housing 2310 . Water of the water supply assembly 2300 may be supplied through the water pipe 2314 . In addition, water discharged from the inside of the steam housing 2310 through the water pipe 2314 may flow to the drain assembly 2700 .

The steam generator 2300 according to the present embodiment is characterized in that one water pipe 2314 is used for supply and drainage of water. In general, in the case of an apparatus for generating steam, a pipe for receiving water and a pipe for discharging water are provided together.

The water pipe 2314 is disposed in a horizontal direction. The water pipe 2314 communicates with the inside and outside of the lower steam housing 2350 . The water pipe 2314 protrudes from the lower steam housing 2350 toward the water supply assembly 2300 . An outer end of the water pipe 2314 protrudes more laterally than a side surface of the lower steam housing 2350 .

The water pipe 2314 is connected to the chamber housing pipe 2214 and is disposed in the left and right directions. In this embodiment, the water pipe 2314 has a hollow pipe shape.

The water pipe 2314 is disposed on the rear side with respect to the front-rear direction of the steam housing 2310 . The water pipe 2314 is preferably disposed close to the drain assembly. The water pipe 2314 is effective in suppressing the temperature rise of the drain assembly 2700 .

The steam heater 2320 is installed in the lower steam housing 2350 . A steam heater installation part 2352 in which the steam heater 2320 is installed is disposed on the rear surface of the lower steam housing 2350 . In this embodiment, the steam heater installation part 2352 includes an opening surface penetrating the lower steam housing 2350 . The steam heater 2320 passes through the steam heater installation part 2352 , and the heater part is disposed inside the lower steam housing 2350 .

The steam heater 2320 includes a first heater unit 2321 and a second heater unit 2322 disposed in parallel, and the first heater unit 2321 and the second heater unit 2322 are coupled, and the steam A heater mount 2354 coupled to the heater installation part 2352 and providing power to the first heater part 2321 and the second heater part 2322, respectively, the first heater part 2321 and the second heater part 2352 It includes a fuse (not shown) that cuts off power provided to the heater unit 2322 .

In this embodiment, a sheath heater is used for the first heater unit 2321 and the second heater unit 2322 .

Each of the first heater unit 2321 and the second heater unit 2322 may be operated independently. For example, power may be applied only to the first heater unit 2321 to generate heat, and power may be applied only to the second heater unit 2322 to generate heat, and the first heater unit 2321 and the second heater may be heated. Power may be applied to all of the units 2322 to generate heat.

The first heater part 2321 and the second heater part 2322 are both formed in a “U” shape.

Each curved part of the first heater part 2321 and the second heater part 2322 is disposed on the side of the steam discharge part 2316 . The first heater part 2321 and the second heater part 2322 are disposed on the same plane. Upper ends 2321a and 2322a of the first heater part 2321 and the second heater part 2322 may be disposed equal to or lower than the lowest water level WL.

In this embodiment, in consideration of the inclination of the indoor unit, upper ends 2321a and 2322a of the first and second heaters 2321 and 2322 are disposed lower than the lowest water level WL.

The base 130 of the indoor unit should be installed horizontally on the ground, but may be inclined in at least one of the forward, backward, left, and right directions due to an installation error. It is preferable that the upper ends 2321a and 2322a of the first heater part 2321 and the second heater part 2322 are not exposed outside the water surface even when the indoor unit is inclined to one side.

To this end, a safety water level WS may be formed between the upper surface 2321a of the first heater unit 2321 and the lowest water level WL. A safety water level WS may be formed between the upper surface 2322a of the second heater unit 2322 and the lowest water level WL.

Therefore, the upper surface 2321a of the first heater part 2321 and the upper surface 2322a of the second heater part 2322 are positioned lower than the lowest water level WL by the safe water level WS. In this embodiment, the safety water level WS is formed to be 6 mm.

The heating capacity of the first heater unit 2321 and the second heater unit 2322 are different from each other. The length of the first heater unit 2321 is shorter than the length of the second heater unit 2322 . The first heater part 2321 is disposed inside the second heater part 2322 .

In this embodiment, the capacity of the first heater unit 2321 is 440W, and the capacity of the second heater unit 2322 is 560W. When the first heater unit 2321 and the second heater unit 2322 are operated together, a maximum output of 1 kW is provided.

The first heater part 2321 is operated when the humidification operation is performed. When steam sterilizing the humidification assembly 2000, the first heater unit 2321 and the second heater unit 2322 are simultaneously operated.

When the steam generator 2300 operates normally, the temperature inside the steam housing 2310 is controlled to about 105 degrees. When the steam generator 2300 is heated, the stored water boils to generate bubbles, and the second water level sensor 2370 detects this and blocks overheating of the steam generator 2300 . When the steam generator 2300 is overheated, the second water level sensor 2370 may be operated at about 140 degrees.

When the second water level sensor 2370 does not detect overheating, the thermistor 2380 detects overheating of the steam generator 2300, and the thermistor 2380 detects a temperature range of 150 to 180 degrees. . In this embodiment, the thermistor 2380 detects 167 degrees or more.

If the temperature inside the steam housing 2310 (250 degrees Celsius in this embodiment) rises even after power control by the thermistor 2380 , the fuse cuts off the power of the steam heater 2320 .

The heater mount 2354 passes through the steam heater installation part 2352 and is coupled to the lower steam housing 2350 . The heater mount 2354 seals the steam heater installation part 2352 . A gasket (not shown) for airtightness may be disposed between the heater mount 2354 and the steam heater installation part 2352 . The water pipe 2314 is disposed on the heater mount 2354 side.

Meanwhile, water inside the supply chamber 2211 is introduced into the water pipe 2314 by its own weight. To this end, the water pipe 2314 is disposed lower than the chamber housing pipe 2214 . In particular, the water pipe 2314 is disposed equal to or lower than the outer end 2214b of the chamber housing pipe 2214 .

In particular, the water pipe 2314 may be connected to the lowermost side of the lower steam housing 2350 . This is to prevent water from accumulating inside the steam housing 2310 when the water stored in the steam housing 2310 is drained. The inner bottom surface of the lower steam housing 2350 may be formed with a groove or a slope for flowing water into the water pipe 2314 .

In this embodiment, a separate valve is not disposed in the water pipe 2314 .

Since the water pipe 2314 and the chamber housing pipe 2214 communicate with each other, the water level of the supply chamber 2211 and the water level of the steam housing 2310 may be formed to be the same.

Specifically, when sufficient water is supplied to the inside of the steam housing 2310 , the water level in the supply chamber 2211 and the water level in the steam housing 2310 are formed to be the same, and the supply of the water supply assembly 2200 is The floater 2220 may rise as the water level rises, and the supply floater 2220 may close the middle hole 2258 to which water is supplied.

In this embodiment, the chamber housing pipe 2214 is disposed within the height of the steam heater 2320 . The outer end 2214b of the chamber housing pipe 2214 is disposed lower than the highest water level WH of the steam generator 2300 .

The highest water level WH of the steam generator 2300 is disposed lower than the valve hole 2111 . The middle hole 2258 is disposed equal to or higher than the highest water level WH of the steam generator 2300 . In this embodiment, the middle hole 2258 forms a separation distance H from the upper ends 2321a and 2322a of the steam heater 2320 .

In this embodiment, since the floater valve stopper 2278 disposed on the supply plotter 2220 protrudes upward from the plotter body 2222, the maximum rising height of the floater body 2222 is the same as the highest water level WH. or it may be low.

However, there is no change in that the middle hole 2258 is closed and the water supply to the steam generator 2300 is blocked when the supply floater 2220 is raised to the maximum.

The steam discharge part 2316 communicates with the inside of the upper steam housing 2340 . The steam discharge part 2316 penetrates the upper steam housing 2340 in the vertical direction. The steam discharge part 2316 protrudes upward from the upper surface of the upper steam housing 2340 for connection with the steam guide 2400 .

The air suction part 2318 is disposed in the steam housing 2310 , and more specifically, disposed in the upper steam housing 2340 . The air suction part 2318 communicates with the inside of the upper steam housing 2340 , and air supplied from the humidifying fan 2500 is introduced.

The air suction part 2318 protrudes upward from the upper surface of the upper steam housing 2340 for connection with the humidifying fan 2500 .

In this embodiment, the air suction part 2318 is disposed behind the steam discharge part 2316 . The air suction part 2318 is disposed closer to the humidification fan 2500 than the steam discharge part 2316 .

The air suction unit 2318 is connected to the humidifying fan 2500 and receives filtered air from the humidifying fan 2500 . The air suction unit 2318 is supplied with air filtered through the filter assembly 600 . The filtered air supplied to the air suction unit 2318 is introduced into the steam housing 2310 and is discharged to the steam discharge unit 2316 together with the steam inside the steam housing 2310 .

When general air, not filtered air, flows into the steam housing 2310, mold and the like are highly likely to grow inside the steam housing 2310.

In this embodiment, since the air supplied to the inside of the steam housing 2310 is limited to filtered air, it is possible to minimize contamination of the inside with bacteria or mold when the steam generator 2300 is not operated.

In the steam generator 2300 according to the present embodiment, the air flow of the humidifying fan 2500 is supplied therein to push the steam out of the steam housing 2310, so that the flow pressure of steam can be maximized.

Unlike the present embodiment, when the humidifying fan has a structure in which the steam is sucked out of the steam housing, the steam inside the steam housing may not be smoothly discharged.

When the steam generated by the steam generator 2300 does not flow to the side discharge ports 301 and 302 quickly, dew condensation may occur in the steam movement process.

In this embodiment, since the humidifying fan 2500 supplies air from the air intake side of the steam generator 2300, dew condensation generated during the flow of steam can be minimized. In addition, in the present embodiment, since the air of the humidifying fan 2500 pushes the steam inside the steam housing 2310 out of the steam housing 2310 , it is possible to secure a sufficient flow rate of air.

In particular, in the case of this embodiment, even if dew condensation occurs during the flow of steam, since the flow rate of the air for flowing the steam is sufficiently secured, the condensed water may be naturally evaporated by the flow speed of the air.

<Configuration of drain assembly>

The drain assembly 2700 is disposed on the base 130, and is connected to a drain pump 2710 for draining water from the water supply assembly 2200 and the steam generator 2300, and the drain pump 2710. A drain hose 2720 for guiding the water pumped from the drain pump 2710 out of the indoor unit, a chamber housing pipe 2214 of the water supply assembly 2200, a water pipe 2314 of the steam generator 2300, and It includes a water connection pipe 2730 for connecting the drain pump 2710 to flow water.

Since the configuration of the drain pump 2710 is a device common to those skilled in the art, a description of its operation will be omitted. The drain pump 2710 includes a drain inlet 2714 connected to the water connection pipe 2730 and a drain outlet 2712 connected to the drain hose 2720 .

The drain inlet 2714 is disposed in a horizontal direction and protrudes toward the steam generator 2300 in this embodiment. The drain outlet 2712 protrudes upward.

In this embodiment, since water in the water supply assembly 2200, the steam generator 2300, and the drain pump 2710 is moved by its own weight, the arrangement of the drain pump 2710 is arranged to satisfy this. Therefore, the drain pump 2710 is preferably disposed lower than the chamber housing pipe 2214 and the water pipe 2314 .

Since the water of the water supply assembly 2200 and the steam generator 2300 is also moved by its own weight, the water pipe 2314 is preferably disposed lower than the chamber housing pipe 2214 .

By this arrangement, the chamber housing pipe 2214 is the highest among the three, the drain pump 2710 is the lowest, and the water pipe 2314 is a chamber housing pipe 2214 and a drain pump ( 2710) are placed at a height between

The water supply assembly 2200 , the steam generator 2300 , and the drain pump 2710 are all disposed on the base 130 of the cabinet assembly 100 . In order to form the above-described height difference, the base 130 forms a height difference.

In this embodiment, the base 130 has a drain pump installation part 133 concave downward.

The base 130 includes a flat base top wall 131 and a drain pump installation part 133 concave downwardly from the base top wall 131 .

The base top wall 131 is positioned higher than the drain pump installation part 133 .

The water connection pipe 2730 includes a first connection pipe 2731 connected to the chamber housing pipe 2214, a second connection pipe 2732 connected to the water pipe 2314, and the drain inlet ( 2714) and a third connector (2733) connected to, and a three-way pipe (2735) connected to the first connector (2731), the second connector (2732), and the third connector (2733). .

The three-way pipe 2735 may be a T-type pipe or a Y-type pipe, and in this embodiment, a T-type pipe is used to minimize the installation space.

One end of the first connection pipe 2731 is coupled to the chamber housing pipe 2214 , and the other end is coupled to the three-way pipe 2735 . Unlike the present embodiment, a valve is installed in the first connection pipe 2731 , and the installed valve may control the flow of the first connection pipe 2731 .

One end of the second connection pipe 2732 is coupled to the water pipe 2314 , and the other end is coupled to the three-way pipe 2735 . A meso filter (not shown) may be installed inside the second connection pipe 2732 . The mesh filter filters the scale generated by the operation of the steam generator and blocks the scale from flowing into the drain pump 2710 .

One end of the third connection pipe 2733 is coupled to the drain inlet 2714 of the drain pump 2710 , and the other end is coupled to the three-way pipe 2735 .

There is no particular restriction on the material of the first connecting pipe 2731 , the second connecting pipe 2732 , and the third connecting pipe 2733 , but in this embodiment, they are made of a synthetic resin material for easy assembly.

Here, the second connection pipe 2732 is preferably formed of a heat-resistant material (EDPM in this embodiment) that can cover the temperature range of the steam generator 2300 because high-temperature water can be introduced. At least the second connection pipe 2732 is preferably formed of a material that does not deform with respect to the temperature (250 degrees Celsius) before the operation of the heater fuse.

Preferably, the entire water connection pipe 2730 is formed of a material that does not deform with respect to the temperature (250 degrees Celsius) before the operation of the heater fuse.

When the steam generator 2300 is operated, the water inside the steam generator 2300 may rise to 100 degrees or more even in a normal case. At this time, when a pipe receiving water and a pipe discharging water are provided, respectively, the temperature rise is slow because the pipe receiving water is connected to the water tank, but only a small amount of water is used in the pipe connected to the drain pump 2710 . Since this is stored, there is a problem in that the temperature rises to a temperature similar to that of the inside of the steam generator 2300 .

When the water temperature of the pipe connected to the drain pump rises, the drain pump may be damaged.

In this embodiment, in order to prevent this, the water of the steam generator 2300 and the water of the water supply assembly 2200 may be mixed in the three-way pipe 2735, and the third connection pipe ( 2733) can be suppressed.

Even if the temperature of the water on the side of the second connection pipe 2732 rises to 100 degrees Celsius or more, since the water on the side of the first connection pipe 2731 forms room temperature, in the three-way pipe 2735, high temperature water and Room temperature water is mixed to suppress the temperature rise of water.

Since the water on the side of the first connection pipe 2731 is supplied with water from the side of the water supply assembly 2200, the temperature rise can be suppressed through convection.

For example, even when the drain pump 2710 is operated while the water inside the steam housing 2310 is at a high temperature after the steam generator 2300 is operated, the high temperature drained from the second connection pipe 2732 is of water and room temperature water drained from the first connection pipe 2731 are mixed in the three-way pipe 2735, and the temperature of the mixed water may be lowered to at least 70 degrees or less.

In this embodiment, the temperature of the water flowing to the drain pump 2710 when draining through the water connection pipe 2730 may be between 30 degrees and 50 degrees.

In this embodiment, when the drain pump 2710 is operated, not only the water stored in the steam housing 2310 but also the water stored in the water tank 2100 and the water supply assembly 2200 are drained.

Since the water used in the humidification assembly 2000 is used for indoor humidification, there is a risk of bacterial growth over time. Therefore, when not used for a predetermined period (24 hours), all of the water stored in the water tank 2100 and the water supply assembly 2200 as well as the steam housing 2310 is drained, and the humidification assembly 2000 is completely dried. can be performed.

When the drain pump 2710 is operated, water on the side of the third connection pipe 2733 is drained. Since one end of the third connection pipe 2733 coupled with the drain inlet 2714 is disposed at the lowest position, the water in the water tank 2100 and the water supply assembly 2200 is discharged from the water tank 2100 and the water supply assembly 2200 by the potential energy of water. It flows to the third connecting pipe 2733 through the first connecting pipe 2731 and the three-way pipe 2735 .

Similarly, water in the steam housing 2310 flows to the third connection pipe 2733 through the second connection pipe 2732 and the three-way pipe 2735 by the potential energy of water.

In this way, the structure of the water connection pipe 2730 can suppress the temperature rise of the steam generator 2300 and easily implement drainage of the entire humidification assembly 2000 .

<<Configuration of Steam Guide>>

The steam guide 2400 supplies the steam of the steam generator 2300 to the discharge passage. The discharge passage includes an air passage flowing by the remote fan assembly 400 and an air passage flowing by the local fan assembly 300 .

In the present embodiment, the discharge flow path is disposed in the cabinet assembly 100 and is defined as until the air that has passed through the filter assembly 600 is discharged out of the cabinet assembly 100 .

In this embodiment, the steam guide 2400 guides the steam generated by the steam generator 2300 to the side outlets 301 and 302 . The steam guide 2400 provides a separate flow path separated from the air inside the cabinet assembly 100 . The steam guide 2400 may be in the form of a tube or duct.

The steam guide 2400 is coupled to the steam generator 2300, the main steam guide 2450 receiving the humidified air of the steam generator 2300, and the main steam guide 2450 are coupled to the main steam A first branch guide 2410 for guiding a portion of the humidified air supplied through the guide 2450 to the first side outlet 301, coupled to the main steam guide 2450, and the main steam guide 2450 A second branch guide 2420 for guiding the rest of the humidified air supplied through the second side outlet 302, and the first branch guide 2410 are assembled and disposed at the first side outlet 301 The first diffuser 2430 for discharging the humidified air supplied through the first branch guide 2410 to the first side outlet 301, and the second branch guide 2420 are assembled, and the second and a second diffuser 2440 disposed at the second side outlet 302 and discharging the humidified air supplied through the second branch guide 2420 to the second side outlet 302 .

Unlike the present embodiment, the first branch guide 2410 and the second branch guide 2420 may be directly coupled to the steam generator 2300 . In this case, the steam generator 2300 is provided with respective steam discharge units to which the first branch guide 2410 and the second branch guide 2420 are coupled.

Also, unlike the present embodiment, it is possible to provide a structure in which only one branch guide is disposed, and the one branch guide is coupled to one diffuser. In this case, one diffuser may be disposed only at any one of the first side discharge port and the second side discharge port.

In the present embodiment, the diffuser is disposed at the side discharge port, but may be installed at the front discharge port. That is, the installation position of the diffuser is not limited to the side discharge port.

In this embodiment, the main steam guide 2450 is formed in the form of a duct. The main steam guide 2450 guides air from the lower side to the upper side. The main steam guide 2450 provides the air (air in which steam and filtered air are mixed) supplied from the steam generator 2300 to the first branch guide 2410 and the second branch guide 2420 .

The air supplied from the steam generator 2300 (air in which steam and filtered air are mixed) is branched from the main steam guide 2450 to a first branch guide 2410 and a second branch guide 2420 .

The lower end of the main steam guide 2450 is coupled to the steam discharge part 2316 of the steam housing 2310 . An upper end of the main steam guide 2450 is coupled to a first branch guide 2410 and a second branch guide 2420 .

The main steam guide 2450 has an open lower side. On the upper side of the main steam guide 2450, a first guide coupling part 2451 to which the first branch guide 2410 is assembled, and a second guide coupling part 2452 to which the second branch guide 2420 is assembled. is placed

The first guide coupling part 2451 and the second guide coupling part 2452 penetrate in the vertical direction. In this embodiment, the first guide coupling portion 2451 and the second guide coupling portion 2452 are formed in a pipe shape.

The first branch guide 2410 is formed in a pipe shape corresponding to the flat cross-section of the first guide coupling part 2451 . The second branch guide 2420 is formed in a pipe shape corresponding to the flat cross-section of the second guide coupling part 2451 .

In this embodiment, since the main steam guide 2450 is biased toward one side (left side) when viewed from the front of the cabinet assembly 100, the first branch guide 2410 and the second branch guide 2420 have different lengths. formed differently.

It is preferable that equal air is supplied to the first branch guide 2410 and the second branch guide 2420 . In this embodiment, the first branch guide 2410 and the second branch guide 2420 have different diameters so that the flow rates of the first branch guide 2410 and the second branch guide 2420 can be uniformly formed. have.

For example, the flow rate can be uniformly formed by reducing the pipe diameter of the short steam guide and increasing the pipe diameter of the long steam guide.

The first diffuser 2430 and the second diffuser 2440 are symmetrical in the left and right directions.

The first diffuser 2430 is assembled with the first branch guide 2410 and is disposed at the first side outlet 301 . The first diffuser 2430 discharges the air supplied together with steam through the first branch guide 2410 to the first side outlet 301 .

Since the steam generator 2300 generates steam by heating water, the temperature of the steam is formed at a high temperature. The temperature of the humidified air discharged from the first diffuser 2430 and the second diffuser 2440 may vary depending on the room temperature, but may be between 50 and 70 degrees Celsius. The humidified air discharged from the first diffuser 2430 and the second diffuser 2440 may cause burns to the user.

Therefore, when the humidifying assembly is operated, the short-distance fan assembly 300 must be operated, and the air discharged from the side grills 151 and 152 must be mixed with the humidified air to lower the temperature of the humidified air.

Therefore, the humidified air discharged from the diffusers 2430 and 2440 is mixed with the air discharged from the side discharge ports 301 and 302 .

The first diffuser 2430 loads and discharges filtered air containing steam in the air discharged from the first side discharge port 301 . The flow velocity of the air discharged from the first diffuser 2430 and the flow velocity of the air discharged through the first side discharge port 301 are formed to be similar. Although the flow rate of the discharge air discharged from the first side discharge port 301 is greater than the flow rate of the humidified air, it is preferable that the flow rate be similar. This is because if one flow rate is greater, it acts as a resistance to the other flow rate.

The air discharged from the first side discharge port 301 may diffuse the steam discharged from the first diffuser 2430 further. The second diffuser 2440 operates in the same principle.

The second diffuser 2440 is assembled with the second branch guide 2420 and is disposed in the second side outlet 302 . The second diffuser 2440 discharges the air supplied with steam through the second branch guide 2420 to the second side outlet 302 .

Since the first diffuser 2430 and the second diffuser 2440 have the same structure, the first diffuser 2430 will be described as an example.

The first diffuser 2430 discharges the air supplied together with steam from the lower side through the side discharge port.

The diffuser (the first diffuser and the second diffuser in this embodiment) passes through a diffuser housing 2460 having a space therein, one side (lower side in this embodiment) opening, and the diffuser housing 2460 The diffuser outlets 2431 and 2441 are formed to be in the same manner, and the diffuser fastening parts 2432 and 2442 which are disposed outside the diffuser housing 2460 and are fastened to the cabinet assembly 100, and the diffuser housing. Diffuser inlets 2433 and 2443 disposed in 2460 and assembled with the steam guides 2420 and 2430, and disposed in the diffuser housing 2460, the diffuser outlets 2431 and 2441 An upper diffuser barrier 2434 that is located on the upper side and protrudes downward, and a lower diffuser barrier 2435 that is disposed in the diffuser housing 2460 and is located below the diffuser outlet 2431 and protrudes upward. ) is included.

For convenience of description, when it is necessary to distinguish the diffuser outlets of the first diffuser 2430 and the second diffuser 2440, the first diffuser outlet 2431 and the second diffuser outlet 2441 are defined as . Similarly, when it is necessary to distinguish the diffuser inlets of the first diffuser 2430 and the second diffuser 2440 , the first diffuser inlet 2433 and the second diffuser inlet 2443 are defined.

The diffuser outlet 2431 is formed in a slit shape. The diffuser outlet 2431 extends long in the vertical direction. A plurality of the diffuser outlets 2431 may be disposed in the longitudinal direction of the diffuser housing 2460 . The diffuser outlet 2431 is disposed to face left or right.

The diffuser outlet 2431 is disposed near the side outlets 301 and 302 of the cabinet assembly 100 .

The first diffuser outlet 2431 is disposed to face the left side of the cabinet assembly 100 , and the second diffuser outlet 2441 is disposed to face the right side of the cabinet assembly 100 .

In this embodiment, the diffuser outlet 2431 is disposed in front of the side discharge ports 301 and 302, and the humidified air can flow further by the air flow discharged from the side discharge ports 301 and 302. .

The diffuser housing 2460 has a diffuser space 2461 formed therein. The diffuser space 2461 communicates with the diffuser inlet 2433 and the diffuser outlet 2431 .

The diffuser space 2461 extends long in the vertical direction. When viewed in a flat cross-section, the inside of the diffuser space 2461 is wide and the outside is narrow.

The diffuser outlet 2431 is disposed outside the diffuser space 2461 . The diffuser inlet 2433 is disposed below the diffuser space 2461 . In this embodiment, the diffuser inlet 2433 is formed in a pipe shape.

The diffuser inlet 2433 is inserted into the steam guide 2420 . The reason that the diffuser inlet 2433 is inserted into the steam guide 2420 is to prevent the condensed water generated inside the diffuser housing 2460 from leaking to the outside.

The condensed water condensed inside the diffuser housing 2460 flows downward by its own weight, moves to the steam guide 2420 through the diffuser inlet 2433, and then passes through the main steam guide 2450 to the steam generator 2300. ) can be recovered.

When the humidifying fan 2500 is operated, condensed water inside the diffuser housing 2460 may be naturally evaporated by the flowing air. When the humidifying fan 2500 is not operated, the condensed water formed inside the diffuser housing 2460 may be recovered to the steam generator 2300 and discharged to the outside through the drain assembly.

The diffuser housing 2460 provides a structure capable of guiding the condensed water formed therein downward. To this end, the diffuser upper wall 2462 and the diffuser lower wall 2464 constituting the diffuser space 2461 form an inclined surface.

The diffuser upper wall 2462 is an inclined surface formed with a high outer side and a lower inner side. The diffuser upper wall 2462 forms an upper wall of the diffuser housing 2460 . The diffuser space 2461 is formed under the diffuser upper wall 2462 . The diffuser upper wall 2462 forms an inclination with respect to the left and right direction. The condensed water formed on the diffuser upper wall 2462 may be easily moved downward along the slope of the diffuser upper wall 2462 .

The diffuser lower wall 2464 is an inclined surface formed with a high outside and low inside. The diffuser lower wall 2464 forms a lower wall of the diffuser housing 2460 . The large fuser space 2461 is formed on the upper side of the diffuser lower wall 2464 . The diffuser lower wall 2464 forms an inclination with respect to the left and right direction. The condensed water formed on the diffuser lower wall 2464 may be easily moved downward along the slope of the diffuser lower wall 2464 .

In addition, the diffuser housing 2460 provides a structure capable of preventing the condensed water formed therein from being discharged to the outside.

The condensed water formed on the diffuser housing 2460 may be scattered out of the diffusers 2430 and 2440 by the flow pressure of the air supplied from the humidifying fan 2500 .

To prevent this, the upper diffuser barrier 2434 and the lower diffuser barrier 2435 are disposed in the diffuser housing 2460 .

The upper diffuser barrier 2434 is disposed on the diffuser upper wall 2462 , and protrudes downward from the diffuser upper wall 2462 .

The upper diffuser barrier 2434 is preferably disposed outside the diffuser upper wall 2462 . The upper diffuser barrier 2434 is disposed on the outermost side of the diffuser upper wall 2462 , protrudes from the uppermost side to the lower side of the diffuser upper wall 2462 , and extends in the front-rear direction from the diffuser upper wall 2462 . .

The upper diffuser barrier 2434 blocks the upper part of the diffuser outlet to limit movement of condensate. Condensed water pushed outward along the diffuser upper wall 2462 by the flow pressure of air is caught by the upper diffuser barrier 2434 and is blocked from being discharged to the outside.

The lower diffuser barrier 2435 is disposed on the diffuser lower wall 2464 and protrudes upward from the diffuser lower wall 2464 .

The lower diffuser barrier 2435 is preferably disposed outside the diffuser lower wall 2464 . The lower diffuser barrier 2435 is disposed on the outermost side of the diffuser lower wall 2464, protrudes upward from the uppermost side of the diffuser lower wall 2464, and extends in the front-rear direction from the diffuser lower wall 2464. .

The lower diffuser barrier 2435 blocks a portion of the lower side of the diffuser outlet to limit the movement of condensate. Condensed water pushed outward along the diffuser lower wall 2464 by the flow pressure of air is caught by the lower diffuser barrier 2435 and is blocked from being discharged to the outside.

In addition, the diffuser housing 2460 forms a front surface of the diffuser space 2461, a front diffuser housing 2463 arranged to face forward, and a rear surface of the diffuser space 2461 are arranged to face the rear. The diffuser housing 2465 and the front diffuser housing 2463 include a protrusion 2466 protruding forward from the outer end 2463a.

The diffuser space 2461 is formed between the front diffuser housing 2463 and the rear diffuser housing 2465 .

The outer surface 2463c of the front diffuser housing 2463 is disposed to face the upper cover 162 . In this embodiment, the outer surface 2463c of the front diffuser housing 2463 forms an angle A2 between the upper cover 162 and the upper cover 162 . Unlike the present embodiment, the outer surface 2463c of the front diffuser housing 2463 may be in close contact with the rear surface of the upper cover 162 , and an angle between them may be zero. An inner surface 2463b of the front diffuser housing 2463 forms a diffuser space 2461 .

The rear diffuser housing 2465 is located in front of the motor cover 318 . In this embodiment, the outer surface 2465c of the rear diffuser housing 2465 is in close contact with the front surface of the motor cover 318 . The inner surface 2465b of the rear diffuser housing 2465 forms the diffuser space 2461 .

The outer end of the motor cover 318 extends to the side grills 151 and 152 . The outer end of the motor cover 318 guides the discharged air to the side grills 151 and 152 .

The diffuser outlet 2431 is disposed between the outer end 2463a of the front diffuser housing 2463 and the outer end 2465a of the rear diffuser housing 2465 .

The diffuser outlet 2431 is formed so that an outer end 2463a of the front diffuser housing 2463 and an outer end 2465a of the rear diffuser housing 2465 are spaced apart in the front-rear direction.

In order to form the diffuser outlet 2431, the outer end 2463a of the front diffuser housing 2463 and the outer end 2465a of the rear diffuser housing 2465 form a separation distance D1 in the front-rear direction.

In this embodiment, the outer end 2463a of the front diffuser housing 2463 protrudes more outward than the outer end 2465a of the rear diffuser housing 2465 . A left-right separation distance D2 is formed between the outer end 2463a of the front diffuser housing 2463 and the outer end 2465a of the rear diffuser housing 2465 .

A length D3 from the outer end 2463a to the front end 2466a of the protrusion 2466 is formed.

A distance D4 is formed from the front end 2466a of the protrusion 2466 to the rear surface 217a of the front panel end. Since the door assembly 200 has a structure that slides in the left and right directions with respect to the cabinet assembly 100, the D4 cannot be set to 0. When D4 is 0, friction and friction noise are generated when the door assembly 200 slides. Since assembly tolerances or manufacturing tolerances of the door assembly 200 and the cabinet assembly 100 are required, even when D4 is 1 mm, it is practically difficult to manufacture. So, technically, it is preferable to set the D4 to 2mm or more.

A separation distance D5 from the outer end 2463a to the outer surface 216a of the second front panel side 216 is formed.

By disposing the outer end 2463a of the front diffuser housing 2463 within the left and right widths of the door assembly 100 , it is possible to minimize dew formation on the surface of the door assembly 200 .

It is preferable that the outer end 2463a of the front diffuser housing 2463 does not protrude out of the door assembly 200 . When the outer end 2463a protrudes out of the door assembly 200, the force of the discharged air discharged from the side grill to flow the humidified air forward is increased. This may cause dew to form on the front panel side.

The outer end 2463a of the front diffuser housing 2463 may be disposed on the same line as the side grills 151 and 152 in the front-rear direction or disposed inside the side grills 151 and 152 .

More precisely, the outer end 2463a of the front diffuser housing 2463 is disposed laterally outside the outer end 155a of the vane 155 disposed on the side grills 151 and 152 . In addition, the front panel side of the front diffuser housing 2463 is disposed outside the outer end 2463a in the lateral direction.

The outer end 2465a of the rear diffuser housing 2465 is located laterally inside the outer end 155a of the vane 155 or the outer end 2463a of the front diffuser housing 2463 . In this embodiment, the outer end 2465a of the rear diffuser housing 2465 is located within the left-right direction length of the vane 155 .

A plurality of vanes 155 form a vane gap (BG). A vane disposed most forward among the plurality of vanes 155 is defined as a first vane 156 .

An outer end 2465a of the rear diffuser housing 2465 is disposed between the outer end 156a of the first vane 156 and the outer end 2463a of the front diffuser housing 2463 .

And in this embodiment, the distance between the outer end 156a of the first vane 156 and the outer end 2463a of the front diffuser housing 2463 is formed to be the same as the vane gap BG.

The diffuser outlets 2431 and 2441 are disposed between the outer end 156a of the first vane 156 and the outer end 2463a of the front diffuser housing 2463 .

The outer end 2465a of the rear diffuser housing 2465 is disposed in front of the outer end 156a of the first vane 156, and the front diffuser is greater than the outer end 2465a of the rear diffuser housing 2465 The outer end 2463a of the housing 2463 is disposed further forward.

The protrusion 2466 is disposed to surround the outer edge 162a of the upper cover 162 . That is, when viewed from the front, the upper cover 162 is positioned between the protrusion (not shown) of the first diffuser 2430 and the protrusion 2466 of the second diffuser 2440 .

The outer end 2463a of the front diffuser housing 2463 is located within the left and right width of the door assembly 100 . That is, the outer end 2463a of the front diffuser housing 2463 does not protrude out of the left edge or the right edge 216a of the door assembly 100 . The D5 is preferably formed to be 1 mm or more.

In the case of D5, the inside direction of the front panel 210 from the left edge or right edge 216a is defined as a (+) length, and the outside direction of the left edge or the right edge 216a is defined as a (-) length. define.

When the front panel 210 is disposed on the same line as the left edge or the right edge 216a (D5=0), dew may form on the surface of the left edge or the right edge 216a.

When the D5 is greater than 1 mm, dew formation can be more effectively reduced. This is because the distance between the outer end 2463a of the front diffuser housing 2463 and the left or right edge 216a of the front panel 210 increases as the value of D5 increases.

In addition, in order to minimize dew formation on the surfaces of the first front panel side 214 and the second front panel side 216 of the front panel 210 , the summed length of D3 and D4 is important.

In this embodiment, the sum length DL of D3 and D4 is formed to be 5 mm or more.

For example, when D3 is 3 mm, D4 must be 2 mm or more, and when D4 is 2 mm, D3 must be 3 mm or more.

As the sum length DL is 5 mm or more, dew formation can be suppressed.

Since the length of the front side of the side grills 151 and 152 increases as the sum length DL increases, it is preferable that the sum length DL be formed to be 5 mm or more and 10 mm or less.

In this embodiment, in consideration of the design tolerance and the manufacturing tolerance, the D3 is formed to be 6 mm to 7 mm, the D4 is formed to be 2 mm to 3 mm in consideration of the assembly tolerance, and the sum length (DL) is set to 8 mm to 10 mm. .

The front diffuser housing 2463 is in close contact with the upper cover 162 covering the front of the upper cabinet 110 . The front diffuser housing 2463 is located at the rear of the upper cover 162 and is in close contact with the rear surface of the upper cover 162 .

The outer end 2463a of the front diffuser housing 2463 is formed to surround the side edge 162a of the upper cover 162 . Since the outer end 2463a of the front diffuser housing 2463 surrounds the side of the upper cover 162 , it is possible to prevent the side surface of the upper cover 162 from being exposed to the outside.

The protrusion 2466 of the front diffuser housing 2463 forms a step with the front diffuser housing 2463 and protrudes forward.

Therefore, the protrusion 2466 of the front diffuser housing 2463 is exposed to the outside. In this embodiment, the protrusion 2466 of the front diffuser housing 2463 is defined as a diffuser housing decoration part.

The diffuser housing decoration portion is disposed on the rear edge of the door assembly 200 and does not protrude further in the lateral direction than the side edge of the door assembly 200 .

Since the diffuser housing decoration portion is disposed to protrude further in the lateral direction than the outer end 2465a of the rear diffuser housing 2465, the straightness of the humidified air discharged from the diffuser 2430 can be improved.

The outer end 2465a of the rear diffuser housing 2465 is disposed inside the side side grills 151 and 152 . Based on the front-rear direction, the outer end 2465a of the rear diffuser housing 2465 is disposed between the side side grills 151 and 152 and the front diffuser housing 2463 .

The rear diffuser housing 2465 is disposed in the inclined direction of the side grills 151 and 152, and minimizes resistance to air discharged through the side discharge ports 301 and 302.

The front diffuser housing 2463 is preferably arranged in the left and right directions. Since the front diffuser housing 2463 is disposed in the left and right directions, it is possible to improve the straightness of the air including steam in the lateral direction.

The upper cover 162 and the front panel body 212 are disposed in parallel.

When viewed in a planar cross-section, an angle between the front surface 200a of the front panel body 212 and the vanes 155 of the side grilles 151 and 152 is defined as A1. The angle A1 may be disposed to face forward and be formed between 40 degrees and 50 degrees. In this embodiment, the angle A1 is formed at 45 degrees.

When viewed in a flat cross-section, an angle between the front surface 200a and the front diffuser housing 2463 is defined as A2 with respect to the front surface 200a of the front panel body 212 .

The angle A2 may be formed to be 0 degrees or more and 40 degrees or less.

As the difference between the angle A1 and the angle A2 increases, dew formation on the front panel side surface can be suppressed. Therefore, the angle A2 is preferably 0 degrees, and in this embodiment, the angle A2 is 5 degrees.

When viewed in a plan view, an angle between the front surface 200a and the rear diffuser housing 2465 is defined as A3 with respect to the front surface 200a of the front panel body 212 .

Preferably, the angle A3 is smaller than the angle of the vane 155 .

Considering the angle A2, the angle A3 is larger than A2 and smaller than A1.

When the inclination angle A3 is greater than the inclination angle A1 of the vane 155, resistance is generated in the air directed to the side grille.

The direction Sh toward which the outer peripheral end of the shroud 314 faces and the front surface 200a of the front panel body 212 form an angle B1 between them.

The direction A toward which the outer peripheral end of the hub 312 faces and the front surface 200a of the front panel body 212 form an angle B2 between them.

The angle B1 between the shrouds 314 is preferably formed to be the same as the angle A1 between the vanes 155 . The angle B2 between the hub 312 and the angle A1 between the vanes 155 is preferably formed.

The direction Sh of the shroud 314, the direction A of the hub 312, and the direction A1 of the vane 155 must be the same or similar to minimize air flow resistance.

In this embodiment, the direction A of the hub 312 and the direction A1 of the vanes 155 are formed to be the same, and the direction Sh of the shroud 314 is formed to be gentler than the angle A1 between them.

In the present embodiment, all of the plurality of vanes 155 of the side grille are disposed between the direction Sh to which the outer circumferential end of the shroud 314 faces and the direction A to which the outer circumferential end of the hub 312 faces.

That is, the vanes 155 are positioned at the rear of the direction Sh in which the outer peripheral end of the shroud 314 faces, and the vanes 155 are positioned in front of the direction A in which the outer peripheral end of the hub 312 faces. ) are located.

And the diffuser outlets 2431 and 2441 are positioned at the rear of the direction A in which the outer peripheral end of the hub 312 is directed. The protrusion 2466 is disposed more rearward in the direction A in which the outer peripheral end of the hub 312 faces.

Therefore, when viewed in a flat cross-section, the diffuser space 2461 inside the diffuser housing 2460 is formed to be wide at the inside and narrow at the outside. When viewed in a flat cross-section, the diffuser space 2461 may be formed in the form of a pointed wedge on the outside.

The diffuser outlet 2431 is disposed at a pointed portion of the diffuser space 2461 . The diffuser outlet 2431 is disposed in front of the side outlets 301 and 302 . The diffuser outlet 2431 is disposed behind the door assembly 200 and disposed in front of the side grills 151 and 152 .

The side outlets 301 and 302 discharge air toward the front right and front left, and the humidified air is discharged toward the front of the side outlets 301 and 302 . When the humidified air is discharged to the front of the side outlets 301 and 302, the humidified air can flow further.

The humidification assembly 2000 according to the present embodiment does not depend only on the output of the humidifying fan 2500 for the arrival distance of moisture when providing humidification. When relying only on the output of the humidifying fan 2500 in order to flow the moisture further, the capacity of the humidifying fan 2500 must be increased or the humidifying fan 2500 must be operated at a high speed.

In this embodiment, when the humidification assembly 2000 is operated, moisture can be loaded into the air flow of the short-distance fan assembly 300 to flow further. In this case, even using the humidifying fan 2500 having a small output capacity, it is possible to provide humidification to a distant place in the room.

If the diffuser outlet 2431 is disposed in the front rather than the rear of the side outlets 301 and 302, the humidified air may flow farther.

Meanwhile, a stream HA of humidified air discharged from the diffuser outlet 2431 and a stream DA of discharged air discharged from the vane 152 may cross each other. In order to cross the stream HA of the humidified air and the stream DA of the discharge air, the inclination direction of the front diffuser housing 2463 and the inclination direction of the vane 152 cross.

<<Configuration of humidification fan>>

The humidification fan 2500 sucks the filtered air that has passed through the filter assembly 600 and supplies it to the steam generator 2300, and the filtered air together with the steam generated by the steam generator 2300 to the steam guide 2400. make it flow

The humidifying fan 2500 generates an air flow for discharging steam and filtered air (referred to as humidified air in this embodiment) from the diffusers 2430 and 2440 .

The humidifying fan 2500 has a humidifying fan housing 2530 that sucks in the filtered air that has passed through the filter assembly 600 and guides the sucked in filtered air to the steam generator 2300, and the lower side of the humidifying fan housing A clean suction duct 2540 connected to 2530, the upper side of which is disposed in front of the filter assembly 600, to provide filtered air passing through the filter assembly 600 to the humidifying fan housing 2530; A humidifying impeller 2510 disposed inside the humidifying fan housing 2530 and flowing the filtered air of the humidifying fan housing 2530 to the steam generator 2300, and disposed in the humidifying fan housing 2530, the It includes a humidification motor 2520 for rotating the humidification impeller (2510).

The clean suction duct 2540 provides the filtered air that has passed through the filter assembly 600 to the humidification fan housing 2530 .

Since the filter assembly 600 is disposed in the upper cabinet 110 and the humidifying fan 2500 is disposed in the lower cabinet 120 , there is a difference in height. That is, the filter assembly 600 is located above the humidifying fan 2500 .

In particular, the filtered air that has passed through the filter assembly 600 flows to the short-distance fan assembly 300 , and the filtered air does not flow or is difficult to flow into the lower cabinet 120 . Specifically, since there is no air outlet in the lower cabinet 120 , the filtered air does not flow or circulate into the lower cabinet 120 unless air is artificially supplied.

In addition, since the drain pan 140 that supports the heat exchange assembly and collects condensed water is disposed on the lower side of the upper cabinet 110, the filtered air inside the upper cabinet 110 flows to the lower cabinet 120 There is no restriction. many.

In this embodiment, the humidification fan housing 2530 is manufactured by assembling three parts in order to simplify the assembly structure and reduce manufacturing costs.

The humidifying fan housing 2530 is formed to surround the front of the first suction space 2551 and comprises a first humidifying fan housing part 2531 constituting a part of the first humidifying fan housing 2550; It is formed to surround the rear of the first suction space 2551, is formed to surround the front of the second suction space 2561, the first suction space discharge part 2553 is formed, and the first humidification fan housing ( 2550) and a second humidifying fan housing part 2532 constituting a part of the second humidifying fan housing 2560, is formed to surround the rear of the second suction space 2561, and the motor installation part ( 2565) is disposed, and a third housing part 2533 constituting the remainder of the second humidifying fan housing 2560 is included.

Since the second humidifying fan housing unit 2532 is commonly used in the first humidifying fan housing 2550 and the second humidifying fan housing 2560, it is possible to simplify the number of parts and reduce manufacturing costs.

A first suction space discharge part 2553 is formed in the second humidification fan housing part 2532 . The first suction space discharge part 2553 is formed to pass through the second humidifying fan housing part 2532 in the front-rear direction.

The first suction space discharge part 2553 protrudes toward the humidification impeller 2510 and is formed in a circular shape.

The second humidifying fan housing part 2532 forms the first suction space discharge part 2553 , and an orifice part 2534 protruding toward the humidification impeller 2510 is formed.

A first suction space 2551 is disposed in the front of the second humidifying fan housing unit 2532 , and a second suction space 2561 is disposed in the rear thereof.

The humidifying impeller 2510 is a centrifugal fan that sucks air toward the center and discharges air in the circumferential direction. The air discharged from the humidifying impeller 2510 flows to the steam generator 2300 through the second humidifying fan housing 2560 .

The flow of filtered air according to the driving of the humidification motor 2520 is as follows.

When the humidification motor 2520 is driven, the humidification impeller 2510 coupled to the humidification motor 2520 is rotated. When the humidification impeller 2510 is rotated, air flow is generated in the humidification fan housing 2530 , and filtered air is sucked through the clean suction duct 2540 .

The filtered air sucked through the clean suction duct 2540 passes through the first suction space 2551 and the first suction space discharge part 92553 of the first humidifying fan housing 2550 to the second humidifying fan housing 2560. is moving The air that has flowed into the second humidifying fan housing 2560 is pressurized by the humidifying impeller 2510, and flows downward along the second humidifying fan housing 2560, and then the second suction opening surface 2562. Through the steam generator 2300 flows into the inside.

The filtered air flowing into the steam housing 2310 through the air intake 2318 of the steam generator 2300 is discharged to the steam discharge unit 2316 together with the steam generated in the steam generator 2300 .

The humidified air discharged from the steam discharge unit 2316 is branched from the main steam guide 2450 to the first branch guide 2410 and the second branch guide 2420 .

23 is an exemplary diagram illustrating a flow flow during a humidification operation according to an embodiment of the present invention. 24 is an exemplary view illustrating a flow flow during a steam sterilization operation according to an embodiment of the present invention.

Referring to FIG. 23 , when the indoor unit according to the present embodiment is humidified, the filtered air passing through the filter assembly 600 is sucked into the humidifying fan 2500 through the clean suction duct 2540, and the humidification motor ( The filtered air sucked by the driving of 2520 flows to the steam generator 2300 .

The air flowing from the humidifying fan 2500 to the steam generator 2500 flows from the upper side to the lower side, and flows into the steam housing 2310 through the air suction part 2318 . The filtered air flowing into the steam housing 2310 may be mixed with the steam generated inside the steam housing 2310 . The filtered air may be mixed with the steam while moving in the horizontal direction inside the steam housing 2310, and humidified air is formed by mixing the steam and the filtered air.

During the humidification operation, power is applied to only the first heater part 2321 of the first heater part 2321 and the second heater part 2322, and only the first heater part 2321 generates heat.

When the humidifying fan 2500 is disposed on the discharge side of the steam generator 2300 and has a structure that sucks air from the steam housing 2310, the steam of the steam generator 2300 flows back to the filter assembly 600 side. There is a possibility of generating condensed water in the filter assembly 600 .

In this embodiment, since the humidification fan 2500 blows air toward the steam generator 2300 to supply filtered air, the steam generated by the steam generator 2300 prevents backflow into the filter assembly 600 . can do.

When the humidifying fan 2500 is not operated, steam may flow backward through the air suction part 2318 . In this embodiment, since the humidifying fan 2500 blows air toward the steam housing 2310 and supplies it, it is possible to prevent the steam generated from the steam generator 2300 from flowing backward to the air intake side.

The humidified air inside the steam housing 2310 is discharged out of the steam housing 2310 through the steam discharge unit 2316 . The main steam guide 2450 is disposed on the steam discharge part 2316 , and the humidified air flows upward along the main steam guide 2450 .

Since the humidified air flowing through the main steam guide 2450 is hotter than the indoor air, it may be increased by a density difference. The humidified air flowing through the main steam guide 2450 may naturally flow from the lower side to the upper side by the difference in air pressure and density by the humidifying fan 2500 .

The humidified air of the main steam guide 2450 is divided into a first branch guide 2410 and a second branch guide 2420 , and then is supplied to the first diffuser 2430 or the second diffuser 2440 .

Condensed water may be generated in the first branch guide 2410 , the second branch guide 2420 , the first diffuser 2430 , or the second diffuser 2440 depending on the condition of the room.

The condensed water generated by the steam guide 2400 is moved downward by its own weight. Condensed water moving from the diffusers 2430 and 2440 to the branch guides 2410 and 2420 by its own weight flows into the upper part of the branch guides 2410 and 2420 through the diffuser inlets 2433 and 2443. do.

When condensed water moves to the branch guides 2410 and 2420 through the diffuser inlets 2433 and 2443, noise may be generated due to interference between the condensed water and air. The condensed water to be moved downwards by its own weight and the humidified air flowing upwards may cause friction, and noise may be generated by the friction.

That is, when the condensed water is separated from the inner surfaces of the diffuser inlets 2433 and 2443, the humidified air flowing upward and the condensed water moving downward by its own weight meet to generate noise.

When the generated condensate is a small amount, it is a noise that a user cannot recognize, but when a large amount of condensed water is generated, a noise that can be recognized by the user is generated. In order to solve this problem, a noise reduction structure capable of reducing the noise of the condensed water is formed in a portion where the diffuser inlets 2433 and 2443 and the branch guides 2410 and 2420 are coupled.

In this embodiment, the inner diameters P1 of the diffuser inlets 2433 and 2443 are smaller than the inner diameters P2 of the branch guides 2410 and 2420 for the noise reduction structure. Through this, a stage GP is formed between the lower ends 2433a of the diffuser inlets 2433 and 2443 and the inner surfaces of the branch guides 2410 and 2420 .

Since the inner diameters P1 of the diffuser inlets 2433 and 2443 are smaller than the inner diameters P2 of the branch guides 2410 and 2420, the condensed water flowing down from the upper side is reduced to the lower end 2433a of the diffuser inlet. is moved to the inner surface 2410a of the branch guide by surface tension.

When air flows from the branch guide to the diffuser inlet, since the inner diameter decreases from P2 to P1, air resistance is formed around the lower end 2433a of the diffuser inlet, and the air stream flows through the branch guides 2410 and 2420. ) causes a phenomenon to flow to the inner diameter P1 of the diffuser inlet rather than the inner surface 2410a.

That is, the condensed water can flow downward along the inner surface 2410a of the branch guide through the stage GP where the inner diameter is narrowed, and due to the wind pressure of the humidified air, the diffuser inlets 2433 and 2443 Separation of condensed water from the inner surface can be minimized.

Unlike this embodiment, the inner diameters P1 of the diffuser inlets 2433 and 2443 and the inner diameters P2 of the branch guides 2410 and 2420 are formed to be the same, and the inner surfaces 2433b of the diffuser inlets are formed to be the same. The inner surface 2410a of the branch guide may be formed as a continuous surface.

On the other hand, the humidified air supplied to the first diffuser 2430 and the second diffuser 2440 is discharged from the first diffuser outlet 2431 and the second diffuser outlet 2441, respectively.

Next, when steam sterilizing the humidification assembly, the humidification fan 2500 is not operated, and only the steam generator 2300 is operated. During the steam sterilization operation, power is applied to both the first heater unit 2321 and the second heater unit 2322 , and only the first heater unit 2321 generates heat.

When both the first heater unit 2321 and the second heater unit 2322 are operated, the water stored in the steam generator 2300 can be quickly heated and the temperature of the generated steam can be rapidly increased, Even with a small amount of water, the entire steam guide 2400 can be sterilized.

After the steam sterilization operation, the water of the steam generator 2300 and the water of the water tank 2100 may be drained together.

The diffusers 12430 and 12440 may be disposed on the rear side of the side discharge ports 301 and 302 . In the diffusers 12430 and 12440 , diffuser inlets 2433 and 2443 are disposed on the rear side, and diffuser outlets 2341 and 2441 are disposed on the front side.

As in the first embodiment, the humidified air stream discharged from the diffusers 12430 and 12440 crosses the discharged air stream.

Since the diffusers 12430 and 12440 are disposed on the rear side of the side discharge ports 301 and 302, interference with the discharge air can be minimized. Since the diffusers 12430 and 12440 are located on the rear side of the side discharge ports 301 and 302 , it is possible to minimize interference of the discharge air with the motor cover 318 .
