Description

Humidifier assembly included in air conditioner {Humidifier included in air conditioner}

The present invention relates to a humidification assembly included in an air conditioner, and more particularly, to a humidification assembly capable of generating humidified air and supplying the generated humidified air to a room.

The split type air conditioner has an indoor unit disposed indoors and an outdoor unit disposed outdoors, and may cool, heat, or dehumidify indoor air through a refrigerant circulating between the indoor unit and the outdoor unit.

Depending on the installation type, the indoor unit of the separate type air conditioner includes a stand-type indoor unit installed upright on the indoor floor, a wall-mounted indoor unit installed by hanging 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 humidifier capable of providing humidification.

In the stand-type indoor unit of Prior Art 1, a humidifier is provided inside a body forming an exterior of the indoor unit. And, the humidifier of the prior art 1 has a structure in which water from a drain pan is stored in a water tank, an absorbent member is wetted with the stored water, and the absorbent member naturally evaporates the absorbed water.

The humidifier of the prior art 1 does not use clean water, but uses condensed water flowing 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 propagate in the foreign substances.

In addition, since the humidifier of the prior art 1 evaporates water inside the main body, the evaporated water may adhere to parts or inner walls of the main body, causing the growth of mold or bacteria in the main body.

In the humidifying device of the prior art 1, even if water is evaporated inside the main body and the blowing fan is operated, all the moisture evaporated by the blowing fan is not discharged to the room, and when the temperature of the indoor heat exchanger is low, it is returned to the surface of the indoor heat exchanger. There was a problem with attaching.

In addition, since the humidity of indoor air is low when the indoor temperature is low, heating is generally performed under indoor conditions requiring humidification. Since the humidifier of the prior art 1 provides humidification using condensate from an indoor heat exchanger, it can provide humidification only during cooling and cannot provide humidification during heating because condensate is not generated.

Korean Registered Utility Model Publication No. 20-0446245 (hereinafter referred to as Prior Art 2) discloses a steam humidifier that boils water to generate steam and discharges the generated steam into the room to humidify the room.

Prior Art 2 has a structure including a water tank, a water supply induction pipe, a heating heater pipe, and a steam discharge pipe, heating water through the heater pipe, and discharging steam into the room through the steam discharge pipe. In the prior art 2, water can be supplied to the heating heater tube through the pressure of the water stored in the water tank, but there is a problem in that a structure capable of draining the stored water is not provided.

As in the prior arts 1 and 2, the device for providing humidification stores water through a water tank, but does not have a structure for draining water when humidification is not needed, so water is stored when not in use. There is a problem that contamination by bacteria or fungi occurs in places where it is.

A water level sensor 2370 and a thermistor 2380 preventing overheating inside the steam housing 2310 are further included.

The steam housing 2310 has a closed structure with the outside. The water pipe 2314, the steam discharge unit 2316, and the 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 preferable to be formed 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 upper side and is concave from the lower side to the lower side.

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

The water pipe 2314 is disposed lower than the chamber housing pipe 2214 of the water supply assembly 2200. 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 the case of FIG. 23 , when the position where the water pipe 2314 is disposed on one side of the steam housing 2310, the voltage input to the drain pump 2710, and the diameter of the water pipe 2314 are different, the drain speed determined is a graph showing In the above, the arrangement of the water pipe 2314 is based on the front and rear direction of the steam housing 2310, the back where the air suction part 2318 is disposed, and the front where the steam discharge part 2316 is disposed. , and the arrangement of the center formed between the front and rear are standard. However, the water pipe 2314 is a portion through which water inside the steam housing 2310 is drained, and is disposed at the lower end of the circumferential surface of the steam housing 2310.

Table 1 is a table summarizing the data obtained from the graph of FIG. 23 .

Referring to FIG. 23 and Table 1 above, it can be seen that when the water pipe 2314 is disposed behind the steam housing 2310, the speed at which water inside the steam housing 2310 is drained increases. This may have an effect on the fact that the air suction unit 2318 is formed at the rear of the steam housing 2310 to pressurize the water inside the steam housing 2310 downward. In addition, the structure in which the drain pump 2710 is disposed at the rear of the steam housing 2310 may have an effect.

In addition, referring to FIG. 23 and Table 1, the water pipe 2314 can determine that the draining speed of the water inside the steam housing 2310 increases as the voltage input to the drain pump 2710 increases. there is. However, it can be seen that the pipe diameter of the water pipe 2314 does not have a significant effect on the drainage speed.

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

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

This is to facilitate the collection of steam inside the upper steam housing 2340 to the steam discharge unit 2316. When the steam discharge part 2316 is formed higher than the air intake part 2318, steam having a low density may be collected below the steam discharge part 2316.

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

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

The first water level sensor 2360 includes a 1-1 water level detection unit 2361 and a 1-2 water level detection unit 2362. The lower ends of the 1-1st water level detection unit 2361 and the 1-2nd 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 1-1st water level detection unit 2361 and the 1-2nd water level detection unit 2362, the control unit senses it.

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

In this embodiment, the second water level sensor 2370 uses an electrode that senses water when it comes in contact with it. The lower end 2370a of the second water level sensor 2370 detects the highest water level WH of the steam generator 2300. When the water level of the steam generator 2300 is higher than the lower end 2370a of the second water level sensor 2370, the operation of the steam heater 2320 may boil over the water. 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 considering the inclination 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 high on one side. In this embodiment, when the indoor unit is tilted to one side by 3 degrees and the steam generator 2300 is maximally operated, 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 is stopped and the drain assembly 2700 is operated to drain 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 1-1st water level detection unit 2361 and the 1-2nd water level detection unit 2362 ( 2361a) should be formed higher than (2362a). In this embodiment, this is defined as an appropriate water level.

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

The larger the area of the air intake unit 2318, the more advantageous it is. In this embodiment, the air intake part 2318 is formed wider than the steam discharge part 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 . In addition, water discharged through the water pipe 2314 inside the steam housing 2310 may flow to the drain assembly 2700 .

The steam generator 2300 according to this embodiment is characterized in that one water pipe 2314 is used for supplying and draining water. In general, in the case of a device generating steam, a pipe for receiving water and a pipe for discharging water are provided together.

The water pipe 2314 is disposed in a horizontal direction. The water pipe 2314 communicates 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 surface of the lower steam housing 2350.

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

In the case of FIG. 24, when the water stored in the steam generator is heated by the steam heater 2320 while changing the pipe diameter and arrangement of the water pipe 2314, it is formed in the first connection pipe 2731. It is a diagram showing the temperature change of the water present in the water supply passage and the drainage passage formed in the third connection pipe 2733. In the above, the arrangement of the water pipe 2314 is based on the front and rear direction of the steam housing 2310, the back where the air suction part 2318 is disposed, and the front where the steam discharge part 2316 is disposed. this will be the criterion

Referring to FIG. 24, when the water stored in the steam generator is heated by the steam heater 2320, the water supply passage formed in the first connection pipe 2731 is higher than the drain passage formed in the third connection pipe 2733. Temperature fluctuations can be large. As the first connection pipe 2731 is inclined upward and forms a flow path extending upward, water heated inside the steam generator 2300 may partially flow upward, causing a temperature change on the water supply path. can

When the water stored in the steam generator is heated by the steam heater 2320, the temperature on the water supply passage or the drain passage is changed because the heated water of the steam generator flows backward into the water supply passage or the drain passage. Therefore, it is preferable to adjust the arrangement and diameter of the water pipe 2314 so that the water heated in the steam generator 2300 does not flow backward through the water supply passage or the drainage passage, or the arrangement of the water pipe is applied. do.

In the water pipe 2314, it can be seen that the smaller the pipe diameter, the smaller the temperature change occurs in the water supply passage and the drainage passage. Referring to FIG. 23, it can be seen that the temperature change of the water pipe 2314 occurs less in the water supply passage and the drainage passage when the pipe diameter is Φ7 than when the pipe diameter is Φ9. The smaller the diameter of the pipe, the greater the flow resistance, so that less water flows from the steam generator 2300 to the water pipe 2314, so that the temperature change on the water supply passage or the drainage passage can be reduced.

When the water pipe 2314 is disposed behind the steam housing 2310, it can be seen that a small temperature change occurs in the water supply passage and the drainage passage. Referring to FIG. 24, when the water pipe 2314 is disposed at the rear of the steam housing 2310 rather than at the front of the steam housing 2310, it is understood that the temperature change occurs less in the water supply passage and the drainage passage. can Water flowing back from the steam generator 2300 may flow into the water supply passage extending upward, and when disposed behind the steam housing 2310, the water supply passage increases as the distance from the water supply assembly 2200 increases. The length of the first connecting pipe 2731 to be formed is increased. The longer the length of the water supply passage, the greater the flow resistance on the water supply passage, so that less water flows from the steam generator 2300 to the water pipe 2314, resulting in less temperature change on the water supply passage or drainage passage. there is.

In addition, the water pipe 2314 according to the present invention is simultaneously connected to the first connection pipe 2731 and the third connection pipe 2733 through the three-way pipe 2735, so that water flowing backward through the water pipe 2314 Since the water flows through the first connection pipe 2731 in which the supply passage is formed, water flowing backward through the third connection pipe 2733 connected to the drain pump 2710 can be blocked. That is, since the first connection pipe 2731, the third connection pipe 2733, and the water pipe 2314 are connected through the three-way pipe 2735, the water flows back to the third connection pipe 2733 where a drainage channel is formed. By minimizing, it is possible to minimize the temperature change on the drainage passage. In addition, the water pipe 2314 is disposed at the rear of the steam housing 2310 to minimize backflow to the first connection pipe 2731 having the water supply passage, thereby minimizing temperature change on the water supply passage.

The water pipe 2314 is disposed at the rear side of the steam housing 2310 based on the front and rear directions. The water pipe 2314 is preferably disposed close to the drain assembly. The water pipe 2314 is effective in suppressing a temperature rise of the drain assembly 2700.

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

In the steam heater 2320, a first heater unit 2321 and a second heater unit 2322 disposed in parallel, and the first heater unit 2321 and the second heater unit 2322 are coupled, and the steam A heater mount 2354 coupled to the heater installation unit 2352 and providing power to the first heater unit 2321 and the second heater unit 2322, respectively; A fuse (not shown) that blocks power provided to the heater unit 2322 is included.

In this embodiment, the first heater unit 2321 and the second heater unit 2322 use a sheath heater.

The first heater unit 2321 and the second heater unit 2322 may operate independently of each other. For example, power may be applied to only the first heater unit 2321 to generate heat, 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 all of the units 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 part 2321 and the second heater part 2322 is disposed on the steam discharge part 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, considering the inclination of the indoor unit, the upper ends 2321a and 2322a of the first and second heater units 2321 and 2322 are disposed lower than the lowest water level WL.

The base 130 of the indoor unit should be installed horizontally on the ground, but may be tilted in at least one of 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 part 2321 and the second heater part 2322 are not exposed to the surface of the water.

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

Therefore, the upper side surface 2321a of the first heater unit 2321 and the upper side surface 2322a of the second heater unit 2322 are positioned below the minimum water level WL by the safety level WS. In this embodiment, the safety level WS is formed to be 6 mm.

Heating capacities of the first heater unit 2321 and the second heater unit 2322 are different. The length of the first heater part 2321 is shorter than that of the second heater part 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 are operated together, a maximum output of 1 kW is provided.

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

During normal operation of the steam generator 2300, the temperature inside the steam housing 2310 is controlled to around 105 degrees. When the steam generator 2300 is heated, the stored water boils to generate bubbles, and the second water level sensor 2370 detects this and blocks the steam generator 2300 from overheating. When the steam generator 2300 overheats, the second water level sensor 2370 may be operated within 140 degrees.

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

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

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

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

In particular, the water pipe 2314 may be connected to the lowermost side of the lower steam housing 2350. This is to prevent water from accumulating inside the steam housing 2310 when the water stored in the steam housing 2310 is drained. An inner bottom surface of the lower steam housing 2350 may have grooves or slopes through which water flows into the water pipe 2314 .

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

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

Specifically, when sufficient water is supplied to the inside of the steam housing 2310, the water level of the supply chamber 2211 and the steam housing 2310 are formed to be the same, and the supply of the water supply assembly 2200 The plotter 2220 rises as the water level rises, and the supply plotter 2220 may 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 disposed lower than the valve hole 2111. The middle hole 2258 is disposed equal to or higher than the highest water level (WH) of the steam generator 2300. In this embodiment, the middle hole 2258 forms a separation distance H from the upper ends 2321a and 2322a of the steam heater 2320.

In this embodiment, since the plotter valve stopper 2278 disposed on the supply plotter 2220 protrudes upward from the plotter body 2222, the maximum elevation of the plotter body 2222 is equal to the highest water level WH. or may be lower.

However, when the supply plotter 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 unit 2316 communicates with the inside of the upper steam housing 2340. The steam discharge part 2316 penetrates the upper steam housing 2340 in a vertical direction. The steam discharge part 2316 protrudes upward from the upper side of the upper steam housing 2340 for connection with the steam guide 2400.

The air intake part 2318 is disposed in the steam housing 2310, and more specifically, disposed in the upper steam housing 2340. The air suction 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 part 2318 protrudes upward from the upper side surface of the upper steam housing 2340 for connection with the humidifying fan 2500 .

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

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

When general air, not filtered air, is introduced into the steam housing 2310, there is a high possibility that mold and the like will propagate inside the steam housing 2310.

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

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 therein to push the steam out of the steam housing 2310.

Unlike the present embodiment, in the case of a structure in which a humidifying fan sucks steam outside the steam housing, steam inside the steam housing may not be smoothly discharged.

When the steam generated by the steam generator 2300 does not quickly flow to the side outlets 301 and 302, dew formation may occur 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. In addition, 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 flow rate of air can be secured.

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

<Configuration of drain assembly>

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

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

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

In this embodiment, since the water in the water supply assembly 2200, the steam generator 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 disposed lower than the chamber housing pipe 2214 and the water pipe 2314.

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

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

The water supply assembly 2200, the steam generator 2300, and the drain pump 2710 are all disposed on the base 130 of the cabinet assembly 100. In order to form the height difference described above, 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 base top wall 131 formed flat and a drain pump installation portion 133 formed concave downward from the base top wall 131 .

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

The drain pump 2710 is installed on the drain pump installation part 133, and water in the water tank 2100 and the steam generator 2300 may be collected in the drain pump 2710. Through this, the amount of water remaining in the humidifying 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 ( 2714), and a three-way pipe 2735 connected to the first connection pipe 2731, the second connection pipe 2732, and the third connection pipe 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 the installation space.

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

One end of the second connection pipe 2732 is coupled to the water pipe 2314, and the other end is coupled to the three-way pipe 2735. A mesh 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 connection pipe 2733 is coupled to the drain inlet 2714 of the drain pump 2710, and the other end is coupled to the three-way pipe 2735.

Although there is no particular restriction on the material of the first connection pipe 2731, the second connection pipe 2732, and the third connection pipe 2733, in this embodiment, they are made of synthetic resin to facilitate assembly.

Here, the second connection pipe 2732 is preferably formed of a heat-resistant material (EDPM in this embodiment) that can cover the temperature range of the steam generator 2300 because high-temperature water can flow therein. At least the second connection pipe 2732 is preferably formed of a material that does not undergo deformation at a temperature (250 degrees Celsius) until the heater fuse operates.

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

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

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

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

Even if the temperature of the water on the side of the second connection pipe 2732 rises above 100 degrees Celsius, since the water on the side of the first connection pipe 2731 forms room temperature, high temperature water and Room temperature water is mixed to suppress the temperature rise of water.

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

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

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

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

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

Since the water used in the humidification assembly 2000 is heated and used in the steam generator 2300, scale may occur on the surface of the steam heater 2320 that heats the water. The scale accumulated on the surface of the steam heater 2320 may act as a factor preventing heat generated by the steam heater 2320 from being transferred to water stored in the steam housing 2310. Therefore, it is preferable to operate the drain assembly 2700 periodically to minimize the occurrence of scale on the surface of the steam heater 2320 or inside the steam housing 2310. That is, as described above, when the humidifier assembly 2000 is not used for a predetermined period (one day), it is preferable to drain all of the water stored in the water tank 2100, the water supply assembly 2200, and the steam housing 2310. do.

Referring to FIG. 25, the temperature of the steam heater 2320 for heating the water inside the steam housing 2310 increases according to whether the drain assembly 2700 according to the present embodiment operates and the operating cycle. difference can be discerned. That is, when the drain assembly 2700 operates once every 3 days, the amount of scale generated is significantly reduced compared to the case where the drain assembly does not operate, and the steam heater 2320 accordingly prevents water inside the steam housing 2310. It can be seen that the temperature of the steam heater 2320 for heating is reduced.

In addition, when the air conditioner according to this embodiment is used for 10 years, the internal temperature of the steam heater 2320 due to scale generation is 207.6 degrees when the drain assembly is not operated, and the drain is cycled once every 3 days. When the assembly 2700 is operated, it can be seen that the internal temperature of the steam heater 2320 is formed at 192.4 degrees. In addition, although not shown in the drawing, when the drain assembly 2700 is operated in the same manner once a day, the internal temperature of the steam heater 2320 is formed at 185.9 degrees, and the surface of the steam heater 2320 or It can be seen that it is desirable to set the operation cycle of the drain assembly 2700 short to minimize the occurrence of scale inside the steam housing 2310.

The heater fuse according to the present embodiment sets the blowdown temperature to 216 degrees, so that even when the drain assembly 2700 does not operate periodically, the heater fuse does not blow even after using the air conditioner for more than 10 years, and the steam heater 2320 ) can have durability that can be operated.

Referring to FIG. 26 , whether or not scale occurs varies depending on whether the drain assembly 2700 according to the present embodiment is operated or not and the operation cycle. That is, when the drain assembly 2700 operates once every 3 days, the amount of scale generated is significantly reduced compared to when the drain assembly does not operate, and the heat transfer rate of the steam heater 2320 increases accordingly, so that the steam heater It can be seen that the internal temperature of 2320 can be kept small.

In addition, when the air conditioner according to this embodiment is used for 10 years, the predicted value of the heat transfer rate due to scale generation is 601W when the drain assembly is not operated, and the drain assembly 2700 is cycled once every 3 days. When operating, it can be seen that the predicted heat transfer rate is formed as 624W. In addition, although not shown in the drawing, when the drain assembly 2700 is operated in the same manner once a day, the predicted value of the heat transfer rate is 631W, and the surface of the steam heater 2320 or the steam housing 2310 It can be seen that it is desirable to set the operation cycle of the drain assembly 2700 short to minimize the occurrence of scale inside.

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

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

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

<<Configuration of Steam Guide>>

The steam guide 2400 supplies steam from the steam generator 2300 to the discharge passage. The discharge flow path includes an air flow path flowed by the remote fan assembly 400 and an air flow path flowed by the local fan assembly.

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

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

The steam guide 2400 is coupled to the steam generator 2300, coupled to the main steam guide 2450 receiving humidified air from the steam generator 2300, and coupled to the main steam guide 2450, the main steam A first branch guide 2410 for guiding some of the humidified air supplied through the guide 2450 to the first side discharge port 301 and coupled to the main steam guide 2450, the main steam guide 2450 The second branch guide 2420, which guides the rest of the humidified air supplied through the second side discharge port 302, and the first branch guide 2410 are assembled and disposed in the first side discharge port 301 and is assembled with the first diffuser 2430 for discharging the humidified air supplied through the first branch guide 2410 to the first side outlet 301 and the second branch guide 2420, A second diffuser 2440 disposed at the second side outlet 302 and discharging the humidified air supplied through the second branch guide 2420 to the second side outlet 302 is included.

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 unit 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, it is possible to provide a structure in which only one branch guide is disposed and the one branch guide is coupled to one diffuser. In this case, one diffuser may be disposed only in either the first side discharge port or the second side discharge port.

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

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

Air supplied from the steam generator 2300 (air mixed with steam and filtered air) 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 part 2316 of the steam housing 2310. The upper end of the main steam guide 2450 is coupled to the first branch guide 2410 and the second branch guide 2420.

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

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

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

In this embodiment, since the main steam guide 2450 is disposed on 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 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 flow rates of the first branch guide 2410 and the second branch guide 2420 can be formed equally by manufacturing the tube diameters of the first branch guide 2410 and the second branch guide 2420 differently. there is.

For example, it is possible to form a uniform flow rate by reducing the tube diameter of a short steam guide and increasing the tube diameter of a 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 in the first side discharge port 301 . The first diffuser 2430 discharges air supplied together with steam through the first branch guide 2410 to the first side outlet 301 .

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

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

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

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

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

The diffuser (first diffuser and second diffuser in this embodiment) passes through a diffuser housing 2460 having a space formed therein and one side (lower side in this embodiment) opened, and the diffuser housing 2460. Diffuser outlets 2431 and 2441 formed in such a way, and a diffuser disposed outside the diffuser housing 2460, disposed in the diffuser housing 2460, and assembled with the steam guides 2420 and 2430 Includes lit 2433 and 2443.

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

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

The diffuser outlet 2431 is disposed near the side 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 in front 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 communicates with the diffuser inlet 2433 and the diffuser outlet 2431. The diffuser space extends vertically in a vertical direction. When viewed in plan view, 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 steam guide 2420. The diffuser inlet 2433 is inserted into the steam guide 2420 to prevent condensate generated inside the diffuser housing 2460 from leaking to the outside.

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

When the humidifying fan 2500 is operated, the condensed water inside the diffuser housing 2460 may be spontaneously evaporated by the flowing air. When the humidifying fan 2500 does not operate, condensed water formed inside the diffuser housing 2460 may be recovered to the steam generator 2300 and may be discharged to the outside through the drain assembly 2700.

When providing humidification, the humidification assembly 2000 according to this embodiment does not depend only on the output of the humidifying fan 2500 for the reach of moisture. When relying only on the output of the humidifying fan 2500 to move the 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 the humidifier assembly 2000 is operated, moisture can be loaded into the air flow of the short-distance fan assembly so that it flows further away. In this case, even if the humidifying fan 2500 having a small output capacity is used, humidification can be provided to a far place in the room.

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

<<Configuration of Humidifying Fan>>

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

In particular, the filtered air that has passed through the filter assembly 600 flows to the short-distance fan assembly 300, and the filtered air does not flow or is difficult to flow to the lower cabinet 120. Specifically, since the lower cabinet 120 does not have a portion through which air is discharged, the filtered air does not flow or circulate inside the lower cabinet 120 unless air is artificially supplied.

In addition, since the drain pan 140 supporting the heat exchange assembly and collecting condensate is disposed below the upper cabinet 110, the flow of filtered air inside the upper cabinet 110 to the lower cabinet 120 is restricted. many.
