The stand-type indoor unit of Prior Art 1 is provided with a humidifying device inside the main body forming the exterior of the indoor unit. In addition, the humidification device of the prior art 1 has a structure in which the water of the drain pan is stored in a water tank, the absorption member is wetted through the stored water, and the absorption member naturally evaporates the absorbed water.

The humidifier of 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 matter separated from the surface of the heat exchanger, and there is a problem that it is highly likely that mold or bacteria will propagate from the foreign matter.

In addition, since the humidification device of the prior art 1 evaporates water inside the body, the evaporated water may adhere to parts or inner walls of the body, causing mold or bacteria to grow inside the body.

In the humidifier of Prior Art 1, water evaporates inside the body, and even if the blower fan is operated, all the moisture evaporated by the blower fan is not discharged to the room. There was a problem of being attached.

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

Korean Utility Model Publication No. 20-0446245 (hereinafter referred to as prior art 2) discloses a steam humidifier that humidifies the room by boiling water to generate steam and releasing the generated steam into the room.

Prior art 2 is a structure that includes a water tank, a water supply guide pipe, a heating heater pipe and a steam discharge pipe, heats water through a heating heater pipe, and discharges steam into the room through a steam discharge pipe. Prior art 2 can supply water to the heating heater pipe through the pressure of the water stored in the water tank, but there is a problem that a structure capable of draining the stored water is not provided.

As in 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 in that contamination by bacteria or mold occurs in the place where it is used.

A steam discharge unit 2316 supplied to the steam guide 2400, disposed in the steam housing 2310, connected to the humidifying fan 2500, and the cabinet assembly 100 from the humidifying fan 2500 It includes an air intake part 2318 for receiving the filtered air inside.

The steam generator 2300 includes a first water level sensor 2360 for sensing the lowest water level WL inside the steam housing 2310, and a second water level sensor 2360 for sensing the highest water level WH inside the steam housing 2310. A water level sensor 2370 and a thermistor 2380 for preventing overheating in the steam housing 2310 are further included.

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

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

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

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

In the case of FIG. 23, when the water pipe 2314 is disposed on one side of the steam housing 2310, the voltage input to the drain pump 2710, and the water pipe 2314, the drainage speed determined when the pipe diameter is changed It is a graph showing. In the above, the arrangement of the water pipe 2314 is, based on the front and rear directions of the steam housing 2310, the back where the air intake part 2318 is arranged, and the front where the steam discharge part 2316 is arranged. , And the arrangement of the center formed between the front and the rear is a reference. 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 that summarizes data found in the graph of FIG. 23.

Referring to FIG. 23 and Table 1 above, when the water pipe 2314 is disposed at the rear of the steam housing 2310, it can be seen that the speed at which water inside the steam housing 2310 is drained is increased. This may affect that the air intake part 2318 is formed behind the steam housing 2310 to apply pressure to the water inside the steam housing 2310 to the lower side. In addition, it may have an effect that the drain pump 2710 is a structure disposed to the rear of the steam housing 2310.

In addition, referring to FIG. 23 and Table 1 above, the water pipe 2314 can find out that as the voltage input to the drain pump 2710 increases, the speed at which water inside the steam housing 2310 is drained increases. have. However, it can be seen that the pipe diameter of the water pipe 2314 does not significantly affect 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 team housing 2340. To this end, in the upper team housing 2340, 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 portion 2346 on which the thermistor 2380 is installed are formed.

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

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

In this embodiment, since the first water level sensor 2360 senses 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 water level of the steam generator 2300, it is installed around the steam discharge part 2316.

Since the first water level sensor 2360 and the second water level sensor 2370 form a height difference, it is possible to minimize the electrode lengths of the first water level sensor 2360 and the second water level sensor 2370.

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 part 2601 and the 1-2th water level detection part 2362 are disposed at the same height. In the present embodiment, the 1-1st water level detection part 2361 and the 1-2th water level detection part 2362 are electrodes. When water comes into contact with the 1-1st water level detection part 2601 and the 1-2th water level detection part 2362, the controller detects them.

In the present embodiment, the lower ends of the 1-1st water level detection part 2601 and the 1-2th water level detection part 2362 are the lowest water level WL for driving the steam generator 2300. If the water level is lower than that of the lower ends 2361a and 2362a of the 1st-1st water level sensing part 2361 and the 1-2th water level sensing part 2362, damage to the steam heater 2320 may occur. Therefore, when the water level is lower than the lower end 2362a and 2362a of the 1st-1st water level sensing part 2601 and the 1-2th water level sensing part 2362, the 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 touches. 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, water may boil and overflow due to the operation of the steam heater 2320. When the water level reaches the lower end 2370a of the second water level sensor 2370, the operation of the steam heater 2320 is stopped.

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

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

The proper water level of the steam generator 2300 is lower than the lower end 2370a of the second water level sensor 2370, and the lower end of the 1-1 water level sensing unit 2601 and the 1-2 water level sensing unit 2362 ( It should be formed higher than 2361a) (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. When the internal temperature of the steam generator 2300 rises above a set value, the thermistor 2380 detects it and stops the operation of the steam heater 2320.

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

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

The water pipe 2314 is disposed in a horizontal direction. The water pipe 2314 communicates the inside and the 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 water stored in the steam generator is heated by the steam heater 2320 while varying the diameter of the water pipe 2314 and the arrangement of the water pipe 2314, it is formed in the first connection pipe 271 It is a view showing the temperature change of the water existing in the water supply passage and the drain 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 directions of the steam housing 2310, the rear where the air intake unit 2318 is arranged, and the front where the steam discharge unit 2316 is arranged. This is the criterion.

Referring to FIG. 24, when water stored in the steam generator is heated by the steam heater 2320, compared to the drain passage formed in the third connecting pipe 2733, the water supply passage formed in the first connecting pipe 271 The temperature change can be largely formed. As the first connection pipe 273 is formed to be inclined upward and forms a flow path extending upward, water heated in the steam generator 2300 may partially flow upward, resulting in a temperature change in the water supply flow path. I can.

When the water stored in the steam generator is heated by the steam heater 2320, the temperature of the water supply passage or the drain passage is changed because the heated water of the steam generator flows back into the feed passage or the drain passage. Therefore, it is preferable to adjust the arrangement and pipe diameter of the water pipe 2314 to apply the pipe diameter or arrangement of the water pipe in which the water heated in the steam generator 2300 does not flow back through the water supply passage or the drain passage. Do.

The water pipe 2314 can grasp that the smaller the pipe diameter, the less temperature change occurs in the water supply passage and the drain passage. Referring to FIG. 23, when the pipe diameter is Φ7 than when the pipe diameter is Φ9, it can be seen that the temperature change occurs less in the water supply passage and the drain passage. Since the smaller the pipe diameter, the greater the flow resistance, and thus less water flowing from the steam generator 2300 to the water pipe 2314 may be formed, so that a temperature change in the water supply passage or the drain passage may be reduced.

When the water pipe 2314 is disposed at the rear of the steam housing 2310, it can be seen that a small change in temperature occurs in the water supply passage and the drain passage. Referring to FIG. 24, when the water pipe 2314 is disposed at the rear of the steam housing 2310 than when the water pipe 2314 is disposed in front of the steam housing 2310, it can be understood that less temperature change occurs in the water supply passage and the drain passage. I can. The water flowing back from the steam generator 2300 may flow into a water supply passage extending upward, and when disposed at the rear of the steam housing 2310, the water supply passage is closed 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 of the water supply passage, so that less water flows from the steam generator 2300 to the water pipe 2314, so that the temperature change in the water supply passage or the drain passage may be reduced. have.

In addition, the water pipe 2314 according to the present invention is simultaneously connected to the first connecting pipe 2731 and the third connecting pipe 2733 through a three-way pipe 2735, so that water flowing back through the water pipe 2314 Since it flows to the first connection pipe 273 in which the supply passage is formed, the movement of water flowing back to the third connection pipe 2733 connected to the drain pump 2710 may be blocked. That is, through the three-way pipe 2735, since the first connection pipe 2731, the third connection pipe 2733, and the water pipe 2314 are connected, the flow back to the third connection pipe 2733 where a drainage passage is formed. By minimizing, it is possible to minimize the temperature change in the drainage channel. In addition, by arranging the water pipe 2314 at the rear of the steam housing 2310, it is possible to minimize backflow to the first connection pipe 2731 having a water supply passage, thereby minimizing a temperature change in the water supply passage.

The water pipe 2314 is disposed at the rear side based on the front and rear directions of the steam housing 2310. It is preferable that the water pipe 2314 is disposed close to the drain assembly. The water pipe 2314 is effective in suppressing an increase in temperature of the drain assembly 2700.

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

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

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

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

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

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

The base 130 of the indoor unit should be installed horizontally on the ground, but may be inclined in at least one of front, rear, left, and right directions due to an installation error. Even when the indoor unit is inclined to either 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 outside the water surface.

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

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

The heating capacities of the first heater part 2321 and the second heater part 2322 are different. The length of the first heater part 2321 is formed to be shorter than the length of the second heater part 2322. The first heater part 2321 is disposed inside the second heater part 2322.

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

The first heater part 2321 is operated when the humidification operation is performed. When the humidification assembly 2000 is steam sterilized, the first heater part 2321 and the second heater part 2322 are operated at the same time.

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

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

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

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

Meanwhile, water inside the supply chamber 2211 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 in the steam housing 2310 when the water stored in the steam housing 2310 is drained. The inner bottom surface of the lower steam housing 2350 may be formed with a groove or inclined to allow water to flow through 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 connected to each other, the water level of the supply chamber 2211 and the water level of the steam housing 2310 may 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 water level of the steam housing 2310 are formed equal, 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 maximum water level WH of the steam generator 2300.

The maximum 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 maximum water level WH of the steam generator 2300. In this embodiment, the middle hole 2258 forms a separation distance H from the upper ends 2321a and 2322a of the steam heater 2320.

In this embodiment, since the floater valve stopper 2278 disposed on the supply plotter 2220 protrudes upward from the floater body 2222, the maximum ascending height of the floater body 2222 is equal to the highest water level (WH). It can be low or low.

However, when the supply plotter 2220 is raised to the maximum, the middle hole 2258 is closed and the water supply provided to the steam generator 2300 is blocked.

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

The air intake part 2318 is disposed in the steam housing 2310, and in more detail, it is disposed in the upper team housing 2340. The air intake part 2318 communicates with the inside of the upper team housing 2340, and air supplied from the humidification fan 2500 is introduced.

The air intake part 2318 protrudes upward from the upper side of the upper team housing 2340 for connection with the humidification fan 2500.

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

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

When general air, not filtered air, flows into the steam housing 2310, there is a very high possibility that mold or 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, when the steam generator 2300 is not operated, contamination of the inside of the steam generator 2300 with bacteria or mold can be minimized.

In the steam generator 2300 according to the present exemplary embodiment, the air flow of the humidifying fan 2500 is supplied to the inside to push the steam out of the steam housing 2310, thereby maximizing the flow pressure of the steam.

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

If the steam generated by the steam generator 2300 does not flow quickly to the side discharge ports 301 and 302, condensation 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, condensation 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 ensured.

In particular, in the present embodiment, even if condensation occurs during the flow of steam, condensed water can be spontaneously evaporated by the flow rate of air because the flow rate of air for flowing the steam is sufficiently secured.

<Composition 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.

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

Since the water of the water supply assembly 2200 and the steam generator 2300 is also moved by 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 above-described height difference, the base 130 forms a height difference.

In this embodiment, the base 130 has a drain pump installation part 133 that is 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 may be installed in the drain pump installation part 133, and water from 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 humidification assembly 2000 can be minimized.

The water connection pipe 2730 includes a first connection pipe 271 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 the 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, a T-shaped pipe is used to minimize the installation space.

One end of the first connector 271 is coupled to the chamber housing pipe 2214, and the other end of the first connector 273 is coupled to the three-way pipe 2735. Unlike the present embodiment, a valve is installed in the first connection pipe 2731, and the installed valve may regulate 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 mewater filter (not shown) may be installed inside the second connector 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.

There is no particular restriction on the material of the first connector 2731, the second connector 2732, and the third connector 2733, but in this embodiment, it is made of a synthetic resin material 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 be introduced. It is preferable that at least the second connector 2732 is formed of a material that does not deform with respect to the temperature (250 degrees Celsius) before the heater fuse is operated.

Preferably, the entire water connector 2730 is made of a material that does not deform with respect to the temperature (250 degrees Celsius) before the heater fuse is operated.

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

When the water temperature of the pipe connected to the drain pump increases, 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 connecting pipe ( 2733) temperature rise can be suppressed.

Even if the temperature of the water on the side of the second connection pipe 2732 rises to 100 degrees Celsius or more, the water on the side of the first connection pipe 271 forms room temperature. Room temperature water is mixed to suppress the increase in water temperature.

Since water is supplied from the water supply assembly 2200 side of the first connection pipe 2731, an increase in temperature can be suppressed through convection.

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

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

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

Since the water used in the humidification assembly 2000 is used for indoor humidification, there is a risk of bacterial growth over time. So, when not in use for a predetermined period (24 hours), the water tank 2100, the water supply assembly 2200, as well as the water stored in the steam housing 2310 are all 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 be generated on the surface of the steam heater 2320 that heats water. The scale accumulated on the surface of the steam heater 2320 may act as an element that prevents heat transfer from heat generated by the steam heater 2320 to water stored in the steam housing 2310. Therefore, it is preferable to operate the drain assembly 2700 periodically to minimize the generation of scale on the surface of the steam heater 2320 or inside the steam housing 2310. That is, when the humidification assembly 2000 is not used for a predetermined period of time (1 day) as described above, it is preferable to drain all of the water stored in the steam housing 2310 as well as the water tank 2100 and the water supply assembly 2200. Do.

Referring to FIG. 25, the temperature of the steam heater 2320 for heating the water in the steam housing 2310 by the steam heater 2320 according to whether the drain assembly 2700 according to the present embodiment is operated and the operation cycle You can see the difference. That is, when the drain assembly 2700 is operated once every 3 days, the amount of scale generated is significantly reduced compared to when the drain assembly is not operated, and accordingly, the steam heater 2320 is It can be seen that the temperature of the steam heater 2320 for heating is decreased.

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

In the heater fuse according to this embodiment, the cut-off temperature is set to 216 degrees, so that even when the drain assembly 2700 does not operate periodically, the heater fuse does not break even when the air conditioner is used for more than 10 years, and the steam heater 2320 ) Can have the durability to operate.

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

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

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

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

In this way, the structure of the water connection pipe 2730 not only suppresses an increase in the temperature of the steam generator 2300, but also facilitates drainage of the entire humidification assembly 2000.

<<Steam Guide Composition>>

The steam guide 2400 supplies steam from the steam generator 2300 to a discharge passage. The discharge passage includes an air passage flowing by the remote fan assembly 400 and an air passage flowing by the near fan assembly.

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

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

The steam guide 2400 is coupled to the steam generator 2300, the main steam guide 2450 receiving humidified air from the steam generator 2300 and the main steam guide 2450, the main steam A first branch guide 2410 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 Assembled with the second branch guide 2420 and the first branch guide 2410 to guide the rest of the humidified air supplied through the second side discharge port 302, and disposed in the first side discharge port 301 The first diffuser 2430 for discharging the humidified air supplied through the first branch guide 2410 to the first side discharge port 301 and the second branch guide 2420 are assembled, and the second branch guide 2420 is assembled. 2 It includes a second diffuser 2440 disposed in the side discharge port 302 and discharges the humidified air supplied through the second branch guide 2420 to the second side discharge port 302.

Unlike the present embodiment, the first branch guide 2410 and the second branch guide 2420 may be directly coupled to the steam generator 2300. In this case, each steam discharge unit to which the first branch guide 2410 and the second branch guide 2420 are coupled is disposed on 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 provides air (air mixed with steam and filtered air) supplied from the steam generator 2300 to the first branch guide 2410 and the second branch guide 2420.

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

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

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

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

In this embodiment, since the main steam guide 2450 is arranged to be skewed toward one side (left side) when viewed from the front of the cabinet assembly 100, the first branch guide 2410 and the second branch guide 2420 have a length Is formed differently.

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

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

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

The first diffuser 2430 is assembled with the first branch guide 2410 and is disposed 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 discharge port 301.

The first diffuser 2430 loads and discharges filtered air including steam in the air discharged from the first side discharge port 301. 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 similarly formed. Although the flow rate of the discharge air discharged from the first side discharge port 301 is greater than the flow rate of the humidified air, it is preferable to form the flow rate similarly. This is because when the flow rate on one side is larger, it acts as a resistance to 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 further. The second diffuser 2440 is also operated 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 discharge port 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 from the lower side to the side discharge port of the air supplied together with the steam.

The diffuser (the first diffuser and the second diffuser in this embodiment) penetrates through the diffuser housing 2460 in which a space is formed therein and one side (lower side in this embodiment) is opened, and the diffuser housing 2460 A diffuser outlet 2431 and 2441 formed to be formed, and a diffuser disposed outside the diffuser housing 2460, disposed on the diffuser housing 2460, and assembled with the steam guides 2420 and 2430 Lit 2433 and 2443 are included.

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

The diffuser outlet 2431 is formed in a slit shape. The diffuser outlet 2431 is elongated in the vertical direction. A plurality of diffuser outlets 2431 may be disposed in a length 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 to face the left side of the cabinet assembly 100, and the second diffuser outlet 2441 is disposed to face the right side of the cabinet assembly 100.

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

The diffuser housing 2460 has a diffuser space therein. The diffuser space is in communication with the diffuser inlet 2433 and the diffuser outlet 2431. The diffuser space extends in a vertical direction. In a 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 leakage of condensed water generated in the diffuser housing 2460 to the outside.

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

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

The humidification assembly 2000 according to the present embodiment does not depend only on the output of the humidification fan 2500 on the reach of moisture when providing humidification. When relying only on the output of the humidifying fan 2500 in order to flow moisture further, 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 humidifying assembly 2000 is operated, moisture may be loaded into the airflow of the near-field fan assembly to allow it to flow further. In this case, even if a humidifying fan 2500 having a small output capacity is used, humidification can be provided to a distant place in the room.

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

<<Composition of humidifying fan>>

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

In particular, the filtered air that has passed through the filter assembly 600 flows to the near-field fan assembly 300, and the filtered air does not flow through the lower cabinet 120 or is difficult to flow. Specifically, since there is no portion of the lower cabinet 120 from which air is discharged, filtered air does not flow or circulate into the lower cabinet 120 unless air is artificially supplied.

In addition, since the drain pan 140 that supports the heat exchange assembly and collects condensate is disposed under the upper cabinet 110, there is no restriction on the flow of the 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 flowing the filtered air inside the upper cabinet 110 into the lower cabinet 120.
