Description

Indoor unit for air conditioner}

The present invention relates to an indoor unit of an air conditioner, and more specifically, to an indoor unit of an air conditioner capable of providing humidified air to a room.

A separate air conditioner has an indoor unit placed indoors and an outdoor unit placed outdoors, and can cool, heat, or dehumidify indoor air through refrigerant circulating between the indoor unit and the outdoor unit.

Depending on the installation type, the indoor unit of the separate air conditioner includes a stand-type indoor unit installed upright on the indoor floor, a wall-mounted indoor unit installed on an indoor wall, and a ceiling-type indoor unit installed on the indoor ceiling.

Conventional stand-type indoor units can dehumidify indoor air during cooling, but cannot humidify indoor air during heating.

Korean Patent Publication No. 10-2013-0109738 (referred to as Prior Art 1) discloses a stand-type indoor unit equipped with a humidifying device capable of providing humidification.

The stand-type indoor unit of prior art 1 is provided with a humidifying device inside the main body that forms the exterior of the indoor unit. And the humidifying device of prior art 1 has a structure that stores water from a drain pan in a water tank, wets an absorbing member with the stored water, and naturally evaporates the water absorbed by the absorbing member.

The humidifying device of prior art 1 does not use clean water, but uses condensate that flows down from the heat exchanger. The water stored in the water tank may contain a large amount of foreign substances separated from the surface of the heat exchanger, and there is a very high probability that mold or bacteria will grow in the foreign substances.

In addition, since the humidifier of prior art 1 evaporates water inside the main body, there is a problem in that the evaporated water may adhere to parts or inner walls of the main body and cause the growth of mold or bacteria inside the main body.

In the humidifying device of prior art 1, water evaporates inside the main body, and even if the blower fan operates, all of the moisture evaporated by the blower fan is not discharged into the room, and when the temperature of the indoor heat exchanger is low, it is deposited on the surface of the indoor heat exchanger. There was a problem with attachment.

Additionally, since the humidity of indoor air is low when the indoor temperature is low, heating is generally performed in indoor conditions that require humidification. Since the humidifying device of prior art 1 provides humidification using condensate from an indoor heat exchanger, there is a problem that it can only provide humidification during cooling and cannot provide humidification during heating because condensate is not generated.

Korean Registered Utility Model Publication 20-0446245 (hereinafter referred to as Prior Art 2) discloses a steam humidifier that generates steam by boiling water and releases the generated steam into the room to humidify the room.

Prior art 2 has a structure that includes a water tank, a water supply inlet pipe, a heating heater pipe, and a steam discharge pipe, heats water through the heater pipe, and discharges steam into the room through the steam discharge pipe. Prior art 2 can supply water to the heater pipe through the pressure of water stored in the water tank, but has a problem in that it does not have a structure for draining the stored water.

Like prior art 1 and 2, devices that provide humidification store water through a water tank, but do not have a structure to drain water when humidification is not needed, so water is stored when not in use. There was a problem of contamination by bacteria or mold in places where it was used.

In this embodiment, water flowing from the water tank 2100 to the supply chamber 2111 undergoes two interruption processes.

First, the water tank valve 2150 opens and closes the valve hole 2111 to control the flow of water. Next, the floater valve 2270 opens and closes the middle hole 2258 to control the flow of water.

Since the water discharged from the water tank 2100 flows into the supply chamber 2111 through two opening and closing processes, oversupply of water can be prevented. Specifically, because the supply floater 2220 additionally controls the supply of water, oversupply of water to the droplet generation module 2300 can be prevented.

Unlike this embodiment, a water level sensor that detects the water level can be placed inside the supply chamber 2211, and an open/close valve can be placed in the chamber housing pipe 2214 to control the amount of water supplied to the droplet generation module 2300. . This structure requires additional water level sensors and on-off valves, which increases production costs, and requires additional cable wiring structures because it is controlled through electrical signals.

In this embodiment, the amount of water supplied to the droplet generation module 2300 is controlled through the supply floater 2220, which rises or falls depending on the water level in the supply chamber 2211, so the water level inside the droplet generation module 2300 Control and water supply can be implemented mechanically.

<<Configuration of droplet generation module>>

Referring to Figures 13 to 17, the droplet generating module 2300 receives water from the water supply assembly 2200 and generates droplets. The droplet generating module 2300 atomizes water into droplets through the vibration of the ultrasonic vibrator 2330.

The droplet generating module 2300 includes a humidifying housing 2310, an ultrasonic vibrator 2330 disposed inside the humidifying housing 2310 and generating vibration by an applied power, and disposed in the humidifying housing 2310. a water pipe 2314 that communicates with the inside of the humidification housing 2310 and through which water flows in or out; a water pipe 2314 disposed in the humidification housing 2310, connected to the humidifying air guide 2400, and a water pipe 2314 generated inside A humidifying discharge unit 2316 that supplies liquid droplets to the humidifying air guide 2400 is disposed in the humidifying housing 2310 and is connected to the humidifying fan 2500, and the filtered air is supplied from the humidifying fan 2500. It includes an air intake unit 2318 that receives air.

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

In this embodiment, the humidifying housing 2310 is made of SPS material. The humidifying housing 2310 includes an upper humidifying housing 2340 and a lower humidifying housing 2350.

The upper humidifying housing 2340 has an open lower side and is concave from the lower side to the upper side. The lower humidification 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 humidification housing 2350, and the humidification discharge portion 2316 and the air intake portion 2318 are disposed in the upper humidification 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.

The air intake portion 2318 and the humidification discharge portion 2316 formed in the upper humidification housing 2340 are formed at different heights. The humidification discharge unit 2316 and the air intake unit 2318 form a height difference (SH), and the humidification discharge unit 2316 is disposed higher than the air intake unit 2318 by the height difference (SH). This is to allow liquid droplets inside the upper humidifying housing 2340 to easily collect into the humidifying discharge unit 2316.

The larger the area of the air intake unit 2318, the more advantageous. In this embodiment, the air intake unit 2318 is formed wider than the humidification discharge unit 2316.

The water pipe 2314 is arranged in a horizontal direction. The water pipe 2314 communicates the inside and outside of the lower humidification housing 2350. The water pipe 2314 protrudes from the lower humidification housing 2350 toward the water supply assembly 2300. The outer end of the water pipe 2314 protrudes further laterally than the side of the lower humidification 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.

That is, since the first connector 2731, the third connector 2733, and the water pipe 2314 are connected through the three-way pipe 2735, the drain passage is formed through the third connector 2733. Reflux can be minimized. Additionally, by placing the water pipe 2314 at the rear of the humidifying housing 2310, backflow of water into the first connection pipe 2731 of the water supply passage can be minimized.

The water pipe 2314 is disposed on the rear side of the humidification housing 2310 based on the front-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 ultrasonic vibrator 2330 is disposed below the humidifying discharge unit 2316. The liquid droplets generated by the ultrasonic vibrator 2330 can be quickly discharged to the humidifying discharge unit 2316 together with filtered air.

In this embodiment, in consideration of the tilt of the indoor unit, the first ultrasonic transducer 2331 and the second ultrasonic transducer 2332 are placed lower than the lowest water level.

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 first ultrasonic transducer 2331 and the second ultrasonic transducer 2332 are not exposed to the surface of the water.

Meanwhile, the water inside the supply chamber 2211 flows into the water pipe 2314 due to 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. The first ultrasonic transducer 2331 and the second ultrasonic transducer 2332 are located lower than the chamber housing pipe 2214 and can move water into the humidifying housing 2310 through their own weight.

In particular, the water pipe 2314 may be connected to the lowermost part of the lower humidification housing 2350. This is to prevent water from accumulating inside the humidifying housing 2310 when draining the water stored in the humidifying housing 2310. The inner bottom surface of the lower humidification 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 humidification housing 2310 can be made the same.

Specifically, when sufficient water is supplied to the inside of the humidification housing 2310, the water level of the supply chamber 2211 and the water level of the humidification 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 placed higher than the ultrasonic transducer 2330.

The highest water level of the droplet generating module 2300 is located lower than the valve hole 2111. The middle hole 2258 is placed equal to or higher than the highest water level of the droplet generating module 2300. In this embodiment, the middle hole 2258 forms a separation distance from the top of the ultrasonic vibrator 2330.

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 may be equal to or lower than the highest water level. there is.

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 droplet generating module 2300 is blocked.

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

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

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

In this embodiment, the air intake unit 2318 is disposed behind the humidification discharge unit 2316. The air intake unit 2318 is disposed closer to the humidification fan 2500 than the humidification 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 humidifying housing 2310 and is discharged to the humidifying discharge unit 2316 together with the liquid droplets inside the humidifying housing 2310.

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

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

The liquid droplet generation module 2300 according to this embodiment can maximize the flow pressure of the humidified air because the air flow of the humidifying fan 2500 is supplied inside and pushes the humidified air out of the humidifying housing 2310.

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

If the droplets generated in the droplet generation module 2300 do not quickly flow to the side discharge ports 301 and 302, dew may occur during the movement of the droplets.

In this embodiment, since the humidifying fan 2500 supplies air from the air intake side of the droplet generating module 2300, dew formation generated during the flow of humidified air can be minimized. Additionally, in this embodiment, since the air of the humidifying fan 2500 pushes the humidifying air inside the humidifying housing 2310 out of the humidifying 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 humidified air, the condensate can be naturally evaporated by the flow rate of the air because the flow rate of the air that flows the liquid droplets is sufficiently secured.

<Configuration of drain assembly>

The drain assembly 2700 is disposed on the base 130 and connected to a drain pump 2710 that drains water from the water supply assembly 2200 and the droplet generating module 2300, and to the drain pump 2710. and 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, and a water pipe 2314 of the droplet generating module 2300. ) and 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 droplet generating module 2300 in this embodiment. The drain outlet 2712 protrudes upward.

In this embodiment, since the water in the water supply assembly 2200, the droplet generation module 2300, and the 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 droplet generating module 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, the droplet generating module 2300, and the 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 drain pump 2710 is installed in the drain pump installation part 133, and water from the water tank 2100 and the droplet generating module 2300 can collect in the drain pump 2710. Through this, the amount of water remaining in the humidification assembly 2000 can be minimized.

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 droplet generating module 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.

In this embodiment, when the drain pump 2710 operates, not only the water stored inside the humidifying 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 and the water supply assembly 2200 as well as the humidification housing 2310 is drained, and the entire humidification assembly 2000 is dried. can be performed.

It is desirable to periodically operate the drain assembly 2700 to minimize the occurrence of scale on the surface of the ultrasonic vibrator 2330 or inside the humidifying housing 2310. That is, when the humidification assembly 2000 is not used for a predetermined period (1 day) as described above, it is desirable to drain all the water stored in the water tank 2100, the water supply assembly 2200, as well as the humidification housing 2310. do.

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 humidifying 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 droplet generating module 2300, but also easily implement drainage of the entire humidification assembly 2000.

<<Composition of humidifying air guide>>

The humidified air guide 2400 supplies humidified air of the droplet generating module 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.

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 humidified air guide 2400 guides the humidified air generated by the droplet generating module 2300 to the side discharge ports 301 and 302. The humidified air guide 2400 provides a separate flow path separated from the air inside the cabinet assembly 100. The humidified air guide 2400 may be in the form of a pipe or duct.

The humidified air guide 2400 is coupled to the droplet generating module 2300, and the main humidified air guide 2450, which receives humidified air from the droplet generating module 2300, is coupled to the main humidified air guide 2450, A first branch guide 2410 that guides some of the humidified air supplied through the main humidified air guide 2450 to the first side outlet 301, is coupled to the main humidified air guide 2450, and the main humidified air guide It is assembled with the second branch guide 2420, which guides the remaining humidified air supplied through 2450 to the second side outlet 302, and the first branch guide 2410, and the first side outlet 301 ) and 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, , It is disposed at the second 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 droplet generating module 2300. In this case, each humidifying discharge unit to which the first branch guide 2410 and the second branch guide 2420 are coupled is disposed in the droplet generating module 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 humidifying air guide 2450 is formed in the form of a duct. The main humidifying air guide 2450 guides air from the bottom to the top. The main humidified air guide 2450 provides humidified air (air mixed with liquid droplets and filtered air) supplied from the droplet generating module 2300 to the first branch guide 2410 and the second branch guide 2420. .

The humidified air supplied from the droplet generating module 2300 branches from the main humidified air guide 2450 to the first branch guide 2410 and the second branch guide 2420.

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

The main humidifying air guide 2450 is open at the bottom. On the upper side of the main humidifying air 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 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 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 humidifying air 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 humidifying air guide and increasing the diameter of the long humidifying air 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 humidified air to the first side outlet 301 through the first branch guide 2410.

The first diffuser 2430 carries humidified air into the air discharged from the first side discharge port 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 discharge port 301 can spread the droplets 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 humidified air to the second side outlet 302 through the second branch guide 2420.

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 humidified air from the lower side through the 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 to form a diffuser, disposed on the outside of the diffuser housing (2460), disposed in the diffuser housing (2460), and assembled with the humidified air guides (2420) (2430) Includes inlets 2433 and 2443.

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. . Likewise, 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 formed therein. The diffuser space is in communication with the diffuser inlet 2433 and the diffuser outlet 2431. The diffuser space extends long in the vertical direction. When viewed in plan cross-section, the inside of the diffuser space is wide and the outside is narrow.

In this embodiment, the diffuser inlet 2433 is formed in a pipe shape.

The diffuser inlet 2433 is inserted into the humidified air guide 2420. The diffuser inlet 2433 is inserted into the humidified air 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 humidifying air guide 2420 through the diffuser inlet 2433, and then passes through the main humidifying air guide 2450 to the droplet generation module. It can be retrieved as (2300).

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 droplet generating module 2300 and discharged to the outside through the drain assembly 2700.

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 humidification assembly 2000, moisture can be loaded into the air flow of the nearby fan assembly 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.

<<Composition of humidifying fan>>

The humidifying fan 2500 sucks in the filtered air that has passed through the filter assembly 600 and supplies it to the droplet generation module 2300, and supplies the filtered air along with the droplets generated by the droplet generation module 2300 to the humidifying air guide ( 2400).

The humidifying fan 2500 generates an air flow that discharges liquid droplets and filtered air (referred to as humidified air in this embodiment) from the diffusers 2430 and 2440.

The humidifying fan 2500 includes a humidifying fan housing 2530 that sucks in filtered air that has passed through the filter assembly 600 and guides the sucked filtered air to the droplet generating module 2300, and the lower side of the humidifying fan. A clean suction duct 2540 connected to the housing 2530, the upper side of which is disposed in front of the filter assembly 600, and providing 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 droplet generating module 2300, and disposed in the humidifying fan housing 2530, , and a humidifying motor 2520 that rotates the humidifying impeller 2510.

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

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 on the upper part of 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 upper end of the clean suction duct 2540 is located inside the upper cabinet 110, and the lower end is located inside the lower cabinet 120. That is, the clean suction duct 2540 provides a flow path for filtered air inside the upper cabinet 110 to flow into the lower cabinet 120.

The clean suction duct 2540 has a first clean duct opening surface 2541 that opens toward the heat exchange assembly or filter assembly 600.

A heater 2570 is disposed in the humidifying fan housing 2530 to supply filtered air. The heater 2570 can heat the filtered air and refine the droplets into small sizes.

When water is converted into droplet form through the ultrasonic transducer 2330, the size of the droplet may be 7 to 10 micrometers. When filtered air is heated through the heater 2570, the size of the generated droplets can be reduced to less than 1 micrometer. If the size of the droplet is miniaturized, the occurrence of dew condensation during movement can be minimized.

The heater 2570 is preferably disposed on the discharge side of the humidifying fan housing 2530. It is advantageous for the air heated in the heater 2570 to flow directly into the humidifying housing 2310 to reduce the size of the droplets.

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 A second humidifying fan housing 2560 is formed in the first humidifying fan housing 2550 and a second humidifying fan housing 2560 guides filtered air to the droplet generating module 2300 by the operation of the humidifying impeller 2510, and the first suction space A first suction opening surface 2552 that communicates with (2551) and is open toward one side (the upper side in this embodiment) is formed in the second humidifying fan housing 2560, and the second suction space 2561 It communicates with and penetrates the second suction opening surface 2562 open toward the other side (lower side in this embodiment), the first humidifying fan housing 2550 and the second humidifying fan housing 2560, and the 1 A first suction space discharge unit 2553 communicating with the suction space 2551 and the second suction space 2561, disposed in the second humidifying fan housing 2560, and on which the humidifying motor 2520 is installed. Includes a motor installation unit (2565).

In this embodiment, the heater 2570 is disposed inside the second humidifying fan housing 2560. The heater 2570 is disposed above the air intake unit 2318 of the droplet generating module 2300.

The first humidifying fan housing 2550 has a first suction opening surface 2552 formed toward the upper side. The clean suction duct 2540 is connected to the suction opening surface 2552. 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 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 into 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 portion 2553 is formed to penetrate the second humidifying fan housing portion 2532 in the front-back direction. The first suction space discharge portion 2553 protrudes toward the humidification impeller 2510, It 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 droplet generating module 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. flows into the droplet generation module 2300.

The filtered air flowing into the humidifying housing 2310 through the air intake unit 2318 of the droplet generating module 2300 is discharged to the humidifying discharge unit 2316 together with the droplets generated in the droplet generating module 2300.

The humidified air discharged from the humidifying discharge unit 2316 branches from the main humidifying air 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).
