<<Configuration of steam generator>>

The steam generator 2300 receives water from the water supply assembly 2200 and generates steam. Since the steam generator 2300 generates steam by heating water, it can provide sterilized steam.

The steam generator 2300 includes a steam housing 2310, a steam heater 2320 disposed inside the steam housing 2310, and a steam heater 2320 that generates heat by applied power, and is disposed in the steam housing 2310. , a water pipe 2314 that communicates with the inside of the steam housing 2310 and through which water flows in or out, is placed in the steam housing 2310, is connected to the steam guide 2400, and supplies steam generated internally. A steam discharge unit 2316 supplies the steam guide 2400, is disposed in the steam housing 2310, and is connected to the humidifying fan 2500, and the cabinet assembly 100 is supplied from the humidifying fan 2500. It includes an air intake unit 2318 that receives internal filtered air.

The steam generator 2300 includes a first water level sensor 2360 that detects the lowest water level (WL) inside the steam housing 2310, and a second sensor 2360 that detects the highest water level (WH) inside the steam housing 2310. It further includes a water level sensor 2370 and a thermistor 2380 to prevent overheating inside the steam housing 2310.

The steam housing 2310 has a structure sealed from the outside. The water pipe 2314, steam discharge unit 2316, and air intake unit 2318 communicate with the outside. The steam housing 2310 is installed on the base 130.

Since the steam housing 2310 stores water heated by the steam heater 2320, it is preferably made of a heat-resistant material. In this embodiment, the steam housing 2310 is made 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 top and is concave from the bottom to the bottom.

In this embodiment, the water pipe 2314 is disposed in the lower steam housing 2350, and the steam discharge portion 2316 and the air intake portion 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. Through the height difference between the water pipe 2314 and the chamber housing pipe 2214, water in the chamber housing pipe 2214 flows into the water pipe 2314 by its own weight.

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). For this purpose, the upper steam housing 2340 includes a first water level sensor installation part 2342 where the first water level sensor 2360 is installed, and a second water level sensor installation part where the second water level sensor 2370 is installed ( 2344) and a thermistor installation portion 2346 where 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 are formed at different heights. The steam discharge unit 2316 and the air intake unit 2318 form a height difference (SH), and the steam discharge unit 2316 is disposed higher than the air intake unit 2318 by the height difference (SH).

This is to allow the steam inside the upper steam housing 2340 to easily collect into the steam discharge portion 2316. If the steam discharge portion 2316 is formed higher than the air intake portion 2318, low-density steam may collect below the steam discharge portion 2316.

In this embodiment, the first water level sensor 2360 detects the low water level of the steam generator 2300 and is installed on the main surface of the air intake unit 2318. The second water level sensor 2370 detects the high water level of the steam generator 2300 and 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. The lower ends of the 1-1 water level detection unit 2361 and the 1-2 water level detection unit 2362 are disposed at the same height. In this embodiment, the 1-1 water level detection unit 2361 and the 1-2 water level detection unit 2362 are electrodes. When water touches the 1-1 water level detection unit 2361 and the 1-2 water level detection unit 2362, the control unit detects it.

In this embodiment, the bottom of the 1-1 water level detection unit 2361 and the 1-2 water level detection unit 2362 is the lowest water level (WL) for driving the steam generator 2300. If the water level is lower than the lower ends (2361a) (2362a) of the 1-1 water level detection unit 2361 and the 1-2 water level detection unit 2362, damage to the steam heater 2320 may occur. Therefore, when the water level becomes lower than the lower ends (2361a) (2362a) of the 1-1 water level detection unit 2361 and the 1-2 water level detection unit 2362, the power provided to the steam heater 2320 is cut off.

In this embodiment, the second water level sensor 2370 uses an electrode that detects when water touches it. The lower end (2370a) of the second water level sensor (2370) detects the highest water level (WH) of the steam generator (2300). If the water level of the steam generator 2300 is higher than the lower end 2370a of the second water level sensor 2370, the water may boil and overflow due to the operation of the steam heater 2320. When the water level reaches 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 that takes into account the tilt of the indoor unit. That is, when the indoor unit is tilted in one direction, the water level inside the steam housing 2310 may be higher on one side. In this embodiment, when the indoor unit is tilted by 3 degrees to one side and the steam generator 2300 is operating at its maximum, the 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 can be stopped and the drain assembly 2700 can 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 lower end of the 1-1 water level detection unit 2361 and the 1-2 water level detection unit 2362 ( It must be formed higher than 2361a)(2362a). In this embodiment, this is defined as the 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 the set value and stops the operation of the steam heater 2320.

The larger the area of the air intake unit 2318, the more advantageous. 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 from the water supply assembly 2300 may be supplied through the water pipe 2314. And water discharged from inside the steam housing 2310 through the water pipe 2314 may flow to the drain assembly 2700.

The steam generator 2300 according to this embodiment has the characteristic of using one water pipe 2314 for supply and drainage of water. In general, a device that generates steam is equipped with a pipe for supplying water and a pipe for discharging water.

The water pipe 2314 is arranged in a horizontal direction. The water pipe 2314 communicates 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. The outer end of the water pipe 2314 protrudes more laterally than the side of the lower steam housing 2350.

The water pipe 2314 is connected to the chamber housing pipe 2214 and is arranged in the left and right directions. In this embodiment, the water pipe 2314 is in the form of a pipe with an empty interior.

The water pipe 2314 is disposed on the rear side of the steam housing 2310 based on the front-to-back direction. The water pipe 2314 is preferably placed 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 portion 2352 where the steam heater 2320 is installed is disposed on the back of the lower steam housing 2350. In this embodiment, the steam heater installation portion 2352 includes an opening that penetrates the lower steam housing 2350. The steam heater 2320 penetrates the steam heater installation portion 2352, and the heater portion is disposed inside the lower steam housing 2350.

The steam heater 2320 is a combination of a first heater unit 2321 and a second heater unit 2322 arranged in parallel, and the first heater unit 2321 and the second heater unit 2322, and the steam A heater mount 2354 coupled to the heater installation unit 2352 and providing power to the first heater unit 2321 and the second heater unit 2322, respectively, and the first heater unit 2321 and the second heater unit 2322. It includes a fuse (not shown) that blocks the power provided to the heater unit 2322.

In this embodiment, the first heater unit 2321 and the second heater unit 2322 are sheath heaters.

The first heater unit 2321 and the second heater unit 2322 may operate independently. For example, power may be applied to only the first heater unit 2321 to generate heat, and power may be applied to only the second heater unit 2322 to generate heat, and the first heater unit 2321 and the second heater may generate heat. Power may be applied to both parts 2322 to generate heat.

Both the first heater unit 2321 and the second heater unit 2322 are formed in a “U” shape.

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

In this embodiment, in consideration of the tilt of the indoor unit, the upper ends 2321a and 2322a of the first heater unit 2321 and the second heater unit 2322 are placed lower than the lowest water level (WL).

The base 130 of the indoor unit must be installed horizontally on the ground, but may be tilted in at least one of the forward, backward, left, and right directions due to installation errors. Even when the indoor unit is tilted to one side, it is preferable that the upper ends 2321a and 2322a of the first heater unit 2321 and the second heater unit 2322 are not exposed to the surface of the water.

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

Therefore, the upper side 2321a of the first heater unit 2321 and the upper side 2322a of the second heater unit 2322 are located below the lowest water level (WL) by the safety water level (WS). In this embodiment, the safety level (WS) is set to 6 mm.

The heat generation capacities of the first heater unit 2321 and the second heater unit 2322 are different. The length of the first heater unit 2321 is shorter than the length of the second heater unit 2322. The first heater unit 2321 is disposed inside the second heater unit 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 operate together, a maximum output of 1kW is provided.

The first heater unit 2321 operates during humidification operation. When steam sterilizing the humidification assembly 2000, the first heater unit 2321 and the second heater unit 2322 are operated simultaneously.

When the steam generator 2300 operates normally, the temperature inside the steam housing 2310 is controlled to around 105 degrees. When the steam generator 2300 is heated, the stored water boils and generates bubbles, and the second water level sensor 2370 detects this to block overheating of the steam generator 2300. When the steam generator 2300 overheats, the second water level sensor 2370 may operate at around 140 degrees.

If 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 about 150 to 180 degrees. . In this embodiment, the thermistor 2380 detects 167 degrees or more.

Even after power control by the thermistor 2380, if the temperature inside the steam housing 2310 (250 degrees Celsius in this embodiment) increases, the fuse cuts off the power to the steam heater 2320.

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

Meanwhile, the water inside the supply chamber 2211 flows into the water pipe 2314 by its own weight. For this purpose, the water pipe 2314 is placed 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 part of the lower steam housing 2350. This is to prevent water from accumulating inside the steam housing 2310 when draining the water stored in the steam housing 2310. The inner bottom surface of the lower steam housing 2350 may be formed with a groove or slope that allows water to flow into the water pipe 2314.

In this embodiment, no separate valve is disposed in the water pipe 2314.

Since the water pipe 2314 and the chamber housing pipe 2214 have a connected structure, the water level of the supply chamber 2211 and the water level of the steam housing 2310 can be made the same.

Specifically, when sufficient water is supplied to the inside of the steam housing 2310, the water level of the supply chamber 2211 and the water level of the steam housing 2310 are formed to be equal, and the supply of the water supply assembly 2200 The floater 2220 rises as the water level rises, and the supply floater 2220 can close the middle hole 2258 through 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 located lower than the valve hole (2111). The middle hole 2258 is placed 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 floater 2220 protrudes higher than the plotter body 2222, the maximum rising height of the plotter body 2222 is equal to the highest water level (WH). It can be low or high.

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

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

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

The air intake portion 2318 protrudes upward from the upper side of the upper steam housing 2340 for connection to the humidifying fan 2500.

In this embodiment, the air intake unit 2318 is disposed behind the steam discharge unit 2316. The air intake unit 2318 is disposed closer to the humidifying fan 2500 than the steam discharge unit 2316.

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

When normal air, rather than filtered air, flows into the steam housing 2310, there is a very high possibility that mold, etc. will grow inside the steam housing 2310.

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

The steam generator 2300 according to this embodiment can maximize the flow pressure of steam because the air flow of the humidifying fan 2500 is supplied inside and pushes steam out of the steam housing 2310.

Unlike this embodiment, if the humidifying fan is structured to suck steam from outside the steam housing, the steam inside the steam housing may not be discharged smoothly.

If the steam generated by the steam generator 2300 does not quickly flow to the side discharge ports 301 and 302, dew may form during the movement of the steam.

In this embodiment, since the humidifying fan 2500 supplies air from the air intake side of the steam generator 2300, dew formation generated during the flow of steam can be minimized. Additionally, in this embodiment, since the air of the humidifying fan 2500 pushes the steam inside the steam housing 2310 out of the steam housing 2310, a sufficient air flow rate can be secured.

In particular, in the case of this embodiment, even if dew condensation occurs during the flow of steam, the condensate can be naturally evaporated by the flow rate of the air because the flow rate of the air that flows the steam is sufficiently secured.

<Configuration of drain assembly>

The drain assembly 2700 is disposed on the base 130 and is connected to a drain pump 2710 that drains water from the water supply assembly 2200 and the steam generator 2300, and to the drain pump 2710. A drain hose 2720 that guides 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 that connects the drain pump 2710 to flow water.

Since the configuration of the drain pump 2710 is a common device to those skilled in the art, description of its operation is 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 arranged in the horizontal direction and protrudes toward the steam generator 2300 in this embodiment. The drain outlet 2712 protrudes upward.

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

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

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

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

In this embodiment, the base 130 is formed with a drain pump installation portion 133 concave downward.

The base 130 includes a flat base top wall 131 and a drain pump installation portion 133 that is concave downward from the base top wall 131.

The base top wall 131 is located higher than the drain pump installation portion 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 ( It includes a third connector 2733 connected to 2714), 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-shaped pipe or a Y-shaped pipe, and in this embodiment, the T-shaped pipe is used to minimize installation space.

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

One end of the second connector 2732 is coupled to the water pipe 2314, and the other end is coupled to the three-way pipe 2735. A water filter (not shown) may be installed inside the second connection pipe 2732. The mesh filter filters 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 connector 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 are no particular restrictions on the materials of the first connector 2731, the second connector 2732, and the third connector 2733, but in this embodiment, they are made of synthetic resin material to facilitate assembly.

Here, the second connection pipe 2732 is preferably made 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 flow in. At least the second connection pipe 2732 is preferably made of a material that does not deform at a temperature (250 degrees Celsius) before the heater fuse is operated.

Preferably, the entire water connection pipe 2730 is made of a material that does not deform at a temperature (250 degrees Celsius) before the heater fuse is operated.

When the steam generator 2300 is operated, the water inside the steam generator 2300 may rise to over 100 degrees even under normal circumstances. At this time, when a pipe for supplying water and a pipe for discharging water are provided, the temperature rise is slow because the pipe for supplying water is connected to the water tank, but only a small amount of water is present in the pipe connected to the drain pump (2710). Because this is stored, there is a problem in that the temperature rises to a temperature similar to that inside the steam generator 2300.

If the water temperature in 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 can be mixed in the three-way pipe 2735, and the mixed water can be used to connect the third connection pipe ( 2733) can suppress the temperature rise.

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

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

For example, after operating the steam generator 2300, even if the drain pump 2710 is operated while the water inside the steam housing 2310 is at a high temperature, the high temperature drained from the second connection pipe 2732 The 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 can be lowered to at least 70 degrees or lower.

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

In this embodiment, when the drain pump 2710 is operated, not only the water stored inside 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 it is not used for a predetermined period of time (24 hours), all water stored in the water tank 2100, the water supply assembly 2200, as well as the steam housing 2310 is drained, and the entire humidification assembly 2000 is dried. can be performed.

When the drain pump 2710 operates, water on the third connection pipe 2733 is drained. Since one end of the third connection pipe 2733 coupled with the drain inlet 2714 is placed at the lowest position, the water in the water tank 2100 and the water supply assembly 2200 is moved to the lower end by the potential energy of the water. It flows to the third connector (2733) through the 1 connector (2731) and the three-way pipe (2735).

Likewise, the 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 due to the potential energy of the water.

In this way, the structure of the water connection pipe 2730 can not only suppress the temperature rise of the steam generator 2300, but also easily drain the entire humidification assembly 2000.

<<Composition of Steam Guide>>

The steam guide 2400 supplies steam from the steam generator 2300 to the discharge passage. The discharge passage includes an air passage flowing by the far-distance fan assembly 400 and an air passage flowing by the near-distance fan assembly 300.

In this embodiment, the discharge passage is disposed in the cabinet assembly 100, and is defined as the period before air passing through the filter assembly 600 is discharged out of the cabinet assembly 100.

In this embodiment, the steam guide 2400 guides steam generated by the steam generator 2300 to the side discharge ports 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 pipe or duct.

The steam guide 2400 is coupled to the steam generator 2300, and is coupled to the main steam guide 2450, which receives humidified air from the steam generator 2300, and the main steam guide 2450. A first branch guide 2410 that guides some of the humidified air supplied through the guide 2450 to the first side outlet 301 is coupled to the main steam guide 2450, and the main steam guide 2450 It is assembled with the second branch guide 2420, which guides the remaining humidified air supplied through to the second side outlet 302, and the first branch guide 2410, and is disposed at the first side outlet 301. It is assembled with a first diffuser 2430 that discharges the humidified air supplied through the first branch guide 2410 to the first side outlet 301 and the second branch guide 2420, and the first diffuser 2430 2 It is disposed at the side outlet 302 and includes a second diffuser 2440 that discharges humidified air supplied through the second branch guide 2420 to the second side outlet 302.

Unlike this embodiment, the first branch guide 2410 and the second branch guide 2420 may be directly coupled to the steam generator 2300. In this case, each steam discharge portion to which the first branch guide 2410 and the second branch guide 2420 are coupled is disposed in the steam generator 2300.

In addition, unlike the present embodiment, only one branch guide is disposed, and a structure in which the one branch guide is coupled to one diffuser can be provided. In this case, one diffuser may be disposed in only one of the first side discharge port or the second side discharge port.

In this embodiment, the diffuser is disposed at the side discharge port, but it may also be installed at the front discharge port. That is, the installation location 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 bottom to the top. The main steam guide 2450 provides air (a mixture of steam and filtered air) supplied from the steam generator 2300 to the first branch guide 2410 and the second branch guide 2420.

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

The lower end of the main steam guide 2450 is coupled to the steam discharge portion 2316 of the steam housing 2310. The upper end of the main steam guide (2450) is coupled with the first branch guide (2410) and the second branch guide (2420).

The main steam guide 2450 is open at the bottom. On the upper side of the main steam guide 2450, there is 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 portion 2451 and the second guide coupling portion 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 the shape of a pipe.

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

In this embodiment, since the main steam guide 2450 is disposed skewed to 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 a length of formed differently.

It is preferable that air is equally supplied to the first branch guide 2410 and the second branch guide 2420. In this embodiment, the pipe diameters of the first branch guide 2410 and the second branch guide 2420 are manufactured differently, so that the flow rate of the first branch guide 2410 and the second branch guide 2420 can be made equal. there is.

For example, the flow rate can be made even by reducing the diameter of the short steam guide and increasing the 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 disposed at the first side discharge port 301. The first diffuser 2430 discharges air supplied along with steam through the first branch guide 2410 to the first side discharge port 301.

Since the steam generator 2300 generates steam by heating water, the temperature of the steam is high. 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. Humidified air discharged from the first diffuser 2430 and the second diffuser 2440 may cause burns to the user.

Therefore, when operating the humidification assembly, the short-distance fan assembly 300 must be operated and the temperature of the humidified air must be lowered by mixing the air discharged from the side grills 151 and 152 with 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 filtered air containing steam into the air discharged from the first side outlet 301 and discharges it. The flow rate of air discharged from the first diffuser 2430 and the flow rate of air discharged through the first side outlet 301 are 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 desirable to have a similar flow rate. This is because if one side's flow rate is greater, it acts as resistance to the other side's flow rate.

The air discharged from the first side outlet 301 can diffuse the steam discharged from the first diffuser 2430 further. The second diffuser 2440 also operates on the same principle.

The second diffuser 2440 is assembled with the second branch guide 2420 and disposed at the second side discharge port 302. The second diffuser 2440 discharges air supplied along 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 air supplied with steam from the lower side through a side discharge port.

The diffuser (the first diffuser and the second diffuser in this embodiment) has a space formed inside and a diffuser housing 2460 that is open on one side (lower side in this embodiment), and penetrates the diffuser housing 2460. Diffuser outlets (2431) (2441) formed in such a way, diffuser fastening parts (2432) (2442) disposed on the outside of the diffuser housing (2460) and fastened to the cabinet assembly (100), and the diffuser housing Diffuser inlets (2433) (2443) disposed in (2460) and assembled with the steam guide (2420) (2430), and disposed in the diffuser housing (2460) and diffuser outlets (2431) (2441) An upper diffuser barrier 2434 located on the upper side and protruding downward, and a lower diffuser barrier 2435 disposed in the diffuser housing 2460, located below the diffuser outlet 2431 and protruding upward. ) includes.

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

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

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

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

In this embodiment, the diffuser outlet 2431 is disposed ahead of the side outlets 301 and 302, and the humidified air can flow farther by the air flow discharged from the side outlets 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 plan 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 diffuser inlet 2433 is inserted into the steam guide 2420 to prevent condensed water generated inside the diffuser housing 2460 from leaking to the outside.

The condensed water condensed inside the diffuser housing 2460 flows downward due to 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 operates, condensed water inside the diffuser housing 2460 may naturally evaporate due to flowing air. When the humidifying fan 2500 does not operate, condensed water condensed inside the diffuser housing 2460 can be recovered by the steam generator 2300 and discharged to the outside through the drain assembly.

The diffuser housing 2460 provides a structure that can guide the condensed water formed inside to the lower side. To this end, the diffuser upper wall 2462 and 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 low inner side. The diffuser upper wall 2462 forms the upper wall of the diffuser housing 2460. The diffuser space 2461 is formed below the diffuser upper wall 2462. The diffuser upper wall 2462 is inclined in the left and right directions. Condensation water condensed on the diffuser upper wall 2462 can 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 outer side and a low inner side. The diffuser lower wall 2464 forms the 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 is inclined in the left and right directions. Condensation water condensed on the diffuser lower wall 2464 can be easily moved downward along the slope of the diffuser lower wall 2464.

In addition, the diffuser housing 2460 provides a structure that prevents condensed water condensed inside from being discharged to the outside.

Condensed water condensed in the diffuser housing 2460 may be scattered out of the diffuser 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 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 downward from the uppermost side of the diffuser upper wall 2462, and extends in the front-back direction from the diffuser upper wall 2462. .

The upper diffuser barrier 2434 blocks the upper part of the diffuser outlet and limits the movement of condensate. The condensed water pushed outward along the diffuser upper wall 2462 by the flow pressure of the 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-back direction from the diffuser lower wall 2464. .

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

And the diffuser housing 2460 forms the front of the diffuser space 2461, and the front diffuser housing 2463 is arranged to face the front, and the rear diffuser housing 2463 forms the back of the diffuser space 2461 and is arranged to face the rear. The diffuser housing 2465 and the front diffuser housing 2463 include a protrusion 2466 that protrudes 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 with the upper cover 162. Unlike this embodiment, the outer surface 2463c of the front diffuser housing 2463 is in close contact with the rear surface of the upper cover 162, and the included angle can be formed as 0. The 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 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 discharge 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 by the outer end 2463a of the front diffuser housing 2463 and the outer end 2465a of the rear diffuser housing 2465 being spaced apart in the front-back direction.

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-back direction.

In this embodiment, the outer end 2463a of the front diffuser housing 2463 protrudes further outward than the outer end 2465a of the rear diffuser housing 2465. A separation distance D2 in the left and right directions 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 is formed from the outer end 2463a to the front end 2466a of the protrusion 2466.

A separation 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 is structured to slide in the left and right directions with respect to the cabinet assembly 100, D4 cannot be set to 0. When D4 is 0, friction and friction noise are generated when the door assembly 200 slides. Since assembly or manufacturing tolerances are required for the door assembly 200 and the cabinet assembly 100, it is practically difficult to manufacture even when D4 is 1 mm. So, technically, it is desirable to set D4 to 2 mm or more.

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

By arranging the outer end 2463a of the front diffuser housing 2463 within the left and right widths of the door assembly 100, dew condensation on the surface of the door assembly 200 can be minimized.

It is desirable that the outer end (2463a) of the front diffuser housing (2463) does not protrude outside 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 humidified air forward increases. 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 grilles 151 and 152 in the front-to-back direction, or may be 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 grill (151) (152). And the front panel side is disposed laterally outside the outer end (2463a) of the front diffuser housing (2463).

The outer end 2465a of the rear diffuser housing 2465 is laterally located 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 and right length of the vane 155.

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

The 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 equal to 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 ahead of the outer end (156a) of the first vane 156, and the front diffuser is positioned further forward 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 widths of the door assembly (100). That is, the outer end 2463a of the front diffuser housing 2463 does not protrude beyond the left or 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 inner direction of the front panel 210 from the left edge or right edge 216a is defined as (+) length, and the outer direction of the left edge or right edge 216a is defined as (-) length. define.

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

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

And in order to minimize dew condensation on the surfaces of the first front panel side 214 and the second front panel side 216 of the front panel 210, the combined length of D3 and D4 is important.

In this embodiment, the combined length (DL) of D3 and D4 is 5 mm or more.

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

When the total length (DL) is 5 mm or more, dew formation can be suppressed.

As the summed length DL becomes longer, the length in front of the side grilles 151 and 152 becomes longer. Therefore, in this embodiment, the summed length DL is preferably formed to be 5 mm or more and 10 mm or less.

In this embodiment, considering design and manufacturing tolerances, D3 is formed to be 6 mm to 7 mm, and considering assembly tolerances, D4 is formed to be 2 mm to 3 mm, and the total length (DL) is set to 8 mm to 10 mm. .

The front diffuser housing 2463 is in close contact with the upper cover 162 that covers the front of the upper cabinet 110. The front diffuser housing 2463 is located behind the upper cover 162 and is in close contact with the back 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, the side of the upper cover 162 can be prevented 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 protruding portion 2466 of the front diffuser housing 2463 is defined as the diffuser housing decoration portion.

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

Since the diffuser housing decoration portion is disposed to protrude further laterally than the outer end 2465a of the rear diffuser housing 2465, the straight flow of 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-to-rear direction, the outer end (2465a) of the rear diffuser housing (2465) is disposed between the side side grills (151) (152) and the front diffuser housing (2463).

The rear diffuser housing 2465 is disposed in an inclined direction of the side grilles 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. By arranging the front diffuser housing 2463 in the left and right directions, the straight flow of air containing steam in the lateral direction can be improved.

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

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

When viewed in plan cross-section, based on the front surface 200a of the front panel body 212, the angle between the front surface 200a and the front diffuser housing 2463 is defined as A2.

The included angle A2 may be formed between 0 degrees and 40 degrees.

The larger the difference between the included angle A1 and the included angle A2, the more it is possible to suppress dew forming on the front panel side surface. Therefore, the included angle A2 is preferably 0 degrees, and in this embodiment, the included angle A2 is formed at 5 degrees.

When viewed in plan cross-section, based on the front surface 200a of the front panel body 212, the angle between the front surface 200a and the rear diffuser housing 2465 is defined as A3.

The included angle A3 is preferably formed to be smaller than the angle of the vane 155.

Considering the included angle A2, the included angle A3 is formed to be larger than A2 and smaller than A1.

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

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.

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.

The included angle B1 of the shroud 314 is preferably formed to be equal to the included angle A1 of the vane 155. The included angle B2 of the hub 312 is preferably formed to be equal to the included angle A1 of the vane 155.

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 vane 155 are formed to be the same, and the direction Sh of the shroud 314 is formed to be gentler than the included angle A1.

In this embodiment, the plurality of vanes 155 of the side grill are disposed between the direction (Sh) toward which the outer peripheral end of the shroud 314 faces and the direction (A) toward which the outer peripheral end of the hub 312 faces.

That is, the vanes 155 are located rearward than the direction (Sh) toward which the outer peripheral end of the shroud 314 faces, and the vanes 155 are located forward from the direction (A) toward which the outer peripheral end of the hub 312 faces. ) are located.

And the diffuser outlets 2431 and 2441 are located rearward of the direction A toward which the outer peripheral end of the hub 312 faces. In the direction A toward which the outer peripheral end of the hub 312 faces, the protrusion 2466 is disposed further rearward.

Therefore, when viewed in plan cross-section, the diffuser space 2461 inside the diffuser housing 2460 is wide on the inside and narrow on the outside. When viewed in plan cross-section, the diffuser space 2461 may be formed in a sharp wedge shape on the outside.

The diffuser outlet 2431 is disposed on a sharp portion of the diffuser space 2461. The diffuser outlet 2431 is disposed ahead of the side discharge ports 301 and 302. The diffuser outlet 2431 is disposed rearward than the door assembly 200 and forward than the side grills 151 and 152.

The side discharge ports 301 and 302 discharge air toward the front right and front left, and humidified air is discharged forward from the side discharge ports 301 and 302. When the humidified air is discharged in front of the side discharge ports 301 and 302, the humidified air can flow farther.

When the humidification assembly 2000 according to this embodiment provides humidification, the reach distance of moisture does not depend solely on the output of the humidification fan 2500. When relying only on the output of the humidifying fan 2500 to move moisture farther, the capacity of the humidifying fan 2500 must be increased or the humidifying fan 2500 must be operated at high speed.

In this embodiment, when operating the humidifying assembly 2000, moisture can be loaded into the air flow of the short-distance fan assembly 300 and flow farther. In this case, even when using a humidifying fan (2500) with a small output capacity, humidification can be provided to a distant part of the room.

If the diffuser outlet 2431 is placed in front of the side discharge ports 301 and 302 rather than behind it, the humidified air can flow farther.

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

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

In particular, the filtered air that passes 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 to the lower cabinet 120. Specifically, since there is no part in the lower cabinet 120 where air is discharged, filtered air does not flow or circulate within the lower cabinet 120 unless air is artificially supplied.

In addition, since the drain pan 140 is disposed on the lower side of the upper cabinet 110 to support the heat exchange assembly and collect condensate, there are restrictions on the flow of filtered air inside the upper cabinet 110 to the lower cabinet 120. many.

The second clean duct portion 2544 may be arranged vertically and across the drain pan 140 in the vertical direction. In this embodiment, the second clean duct portion 2544 is located in front of the drain pan 140.

The second clean duct portion 2544 is formed with a second clean duct opening surface 2543 that communicates with the first suction opening surface 2552 of the first humidifying fan housing 2550, which will be described later.

The humidifying fan housing 2530 is coupled to the clean suction duct 2540, filtered air is sucked, and a first humidifying fan housing 2550 is formed with a first suction space 2551 therein, and the first humidifying fan It is combined with the housing 2550 to receive filtered air from the first humidifying fan housing 2550, a second suction space 2561 is formed inside, the humidifying impeller 2510 is disposed therein, and the It is formed in the second humidifying fan housing 2560, which guides filtered air to the steam generator 2300 by the operation of the humidifying impeller 2510, and the first humidifying fan housing 2550, and the first suction space ( 2551) and a first suction opening surface 2552 open toward one side (the upper side in this embodiment), formed in the second humidifying fan housing 2560, and the second suction space 2561, It communicates with the second suction opening surface 2562 that is open toward the other side (the lower side in this embodiment), and penetrates the first humidifying fan housing 2550 and the second humidifying fan housing 2560, and the first A first suction space discharge unit 2553 that communicates the suction space 2551 and the second suction space 2561, and a motor disposed in the second humidifying fan housing 2560 and on which the humidifying motor 2520 is installed.

On the other hand, the second humidifying fan housing 2560 has a second suction opening surface 2562 formed toward the lower side.

In this embodiment, the opening direction of the first suction opening surface 2552 and the opening direction of the second suction opening surface 2562 are opposite.

The lower side 2554 of the first humidifying fan housing 2550 is formed in a round shape and is located lower than the first suction space discharge portion 2553. The upper side 2564 of the second humidifying fan housing 2560 is formed in a round shape and is located above the first suction space discharge portion 2553.

The motor shaft (not shown) of the humidifying motor 2520 penetrates the second humidifying fan housing 2560 and is assembled to the humidifying impeller 2510.

The motor installation part 2565 protrudes rearward from the second humidifying fan housing 2560, and the humidifying motor 2520 is inserted and installed in the motor installation part 2565.

The first humidifying fan housing 2550 with the first suction space 2551 and the second humidifying fan housing 2560 with the second suction space 2561 may be manufactured and then assembled.

In this embodiment, the humidifying fan housing 2530 is manufactured by assembling three parts 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 includes a first humidifying fan housing portion 2531 that forms a part of the first humidifying fan housing 2550, and the It is formed to surround the rear of the first suction space 2551, and is formed to surround the front of the second suction space 2561, the first suction space discharge portion 2553 is formed, and the first humidifying fan housing ( 2550) and a second humidifying fan housing portion 2532 constituting a portion of the second humidifying fan housing 2560, formed to surround the rear of the second suction space 2561, and the motor installation portion ( 2565) is disposed and includes a third housing portion 2533 that constitutes the remainder of the second humidifying fan housing 2560.

Since the second humidifying fan housing part 2532 is commonly used in the first humidifying fan housing 2550 and the second humidifying fan housing 2560, the number of parts can be simplified and the manufacturing cost can be reduced.

A first suction space discharge part 2553 is formed in the second humidifying fan housing part 2532. The first suction space discharge part 2553 is formed to penetrate the second humidifying fan housing part 2532 in the front-back direction.

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

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

The second humidifying fan housing part 2532 has a first suction space 2551 at the front and a second suction space 2561 at the rear.

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 humidifying motor 2520 is as follows.

When the humidifying motor 2520 is driven, the humidifying impeller 2510 coupled to the humidifying motor 2520 rotates. When the humidifying impeller 2510 rotates, air flow is generated within the humidifying fan housing 2530, and filtered air is sucked in 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 outlet 92553 of the first humidifying fan housing (2550) to the second humidifying fan housing (2560). It flows. The air flowing into the second humidifying fan housing 2560 is pressurized by the humidifying impeller 2510, flows downward along the second humidifying fan housing 2560, and then flows through the second suction opening surface 2562. It flows into the steam generator (2300).

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

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

The humidified air flowing through the first branch guide 2410 is discharged to the first side outlet 301 through the first diffuser 2440, and the humidified air flowing through the second branch guide 2420 is discharged through the second diffuser. It is discharged to the second side discharge port (302) through (2450).

Figure 23 is an exemplary diagram showing the flow during humidification operation according to one embodiment of the present invention. Figure 24 is an exemplary diagram showing the flow during steam sterilization operation according to one embodiment of the present invention.

Referring to FIG. 23, when the indoor unit according to this embodiment is operated to humidify, the filtered air passing through the filter assembly 600 is sucked into the humidifying fan 2500 through the clean suction duct 2540, and the humidifying motor ( The filtered air sucked by the drive (2520) flows to the steam generator (2300).

The air flowing from the humidifying fan 2500 to the steam generator 2500 flows from top to bottom and flows into the steam housing 2310 through the air intake part 2318. The filtered air flowing inside 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 horizontally inside the steam housing 2310, and humidified air is formed through mixing of the steam and the filtered air.

During the humidifying operation, power is applied to only the first heater unit 2321 among the first heater unit 2321 and the second heater unit 2322, and only the first heater unit 2321 generates heat.

When the humidifying fan 2500 is disposed on the discharge side of the steam generator 2300 and has a structure to suck air from the steam housing 2310, steam from the steam generator 2300 flows back toward the filter assembly 600. There is a possibility that condensate may be generated in the filter assembly 600.

In this embodiment, the humidifying fan 2500 blows air toward the steam generator 2300 to supply filtered air, thereby preventing the steam generated in the steam generator 2300 from flowing back into the filter assembly 600. can do.

If the humidifying fan 2500 does not operate, steam may flow back through the air intake unit 2318. In this embodiment, since the humidifying fan 2500 supplies air by blowing it toward the steam housing 2310, it is possible to prevent the steam generated by the steam generator 2300 from flowing back toward 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 upper part of 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 indoor air, it may rise due to a density difference. The humidified air flowing through the main steam guide 2450 may naturally flow from the lower side to the upper side due to the difference in air pressure and density caused by the humidifying fan 2500.

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

Depending on indoor conditions, 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.

Condensate generated in the steam guide 2400 is moved downward by its own weight. Condensate moved from the diffuser (2430) (2440) to the branch guides (2410) (2420) by its own weight flows into the upper part of the branch guide (2410) (2420) through the diffuser inlet (2433) (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. Condensate moving downward due to its own weight and humidified air flowing upward generate friction, and noise may be generated due to the friction.

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

When a small amount of condensate is generated, the noise is so loud that the user cannot perceive it, but when a large amount of condensate is generated, the noise is so loud that the user can perceive it. To solve this problem, a noise reduction structure capable of reducing the condensate noise is formed at a portion where the diffuser inlet (2433) (2443) and the branch guide (2410) (2420) are joined.

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

Since the inner diameter (P1) of the diffuser inlet (2433) (2443) is smaller than the inner diameter (P2) of the branch guide (2410) (2420), the condensate flowing from the upper side is at the bottom (2433a) of the diffuser inlet. It 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 guide (2410) (2420) ) causes the phenomenon of trying to flow to the inner diameter (P1) of the diffuser inlet rather than the inner surface (2410a) of the diffuser inlet.

That is, through the stage (GP) where the inner diameter is narrowed, condensate can flow downward along the inner surface (2410a) of the branch guide, and the wind pressure of the humidified air causes the condensate to flow downward in the diffuser inlet (2433) (2443). Separation of condensate from the inner surface can be minimized.

Unlike this embodiment, the inner diameter (P1) of the diffuser inlet (2433) (2443) and the inner diameter (P2) of the branch guide (2410) (2420) are formed to be the same, and the inner side (2433b) of the diffuser inlet The inner surface 2410a of the branch guide may be formed as a continuous surface.

Meanwhile, 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 humidifying fan 2500 does not operate and only the steam generator 2300 operates. 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. The entire steam guide (2400) can be sterilized with a small amount of water.

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

The diffusers 12430 and 12440 may be disposed rearward than the side discharge ports 301 and 302. The diffuser (12430) (12440) has diffuser inlets (2433) (2443) disposed on the rear side, and diffuser outlets (2341) (2441) are disposed on the front side.

Similar to the first embodiment, the stream of humidified air discharged from the diffusers 12430 and 12440 intersects the stream of discharged air.

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

In the first embodiment, the filtered air that has exchanged heat with the heat exchange assembly 500 is supplied to the humidification assembly. In this embodiment, humidified air is generated using filtered air that has not exchanged heat with the heat exchange assembly 500 and has only passed through the second filter assembly 602.

If the indoor unit is operated for a long time, there is a possibility that foreign substances may adhere to the surface of the heat exchange assembly 500. In this embodiment, it is possible to prevent foreign substances separated from the heat exchange assembly 500 from being sucked into the humidification assembly 2000.
