Description

Technical Field

[0001] The present invention relates to a steam generator, and more particularly, to a steam generator mounted inside an indoor unit of an air conditioner for discharging humidified air.

Background Art

[0002] In a split-type air conditioner, an indoor unit is arranged indoors and an outdoor unit is arranged outdoors, and the indoor environment can be comfortably adjusted through a refrigerant circulating between the indoor unit and the outdoor unit. To enhance the comfort of the indoor space, the air conditioner can perform functions such as cooling, heating, or dehumidifying to control the temperature of the indoor space. However, recently, there has been an increasing demand for an air conditioner that can perform a humidifying function to adjust the humidity of the indoor space in order to enhance the comfort of the indoor space.

[0003] Korean Patent Publication No. 10-2013-0109738 (referred to as Prior Art 1) discloses a stand-type indoor unit equipped with a humidifying device capable of providing humidification, and discloses an air conditioner capable of controlling the humidity of the indoor space.

[0004] The stand-type indoor unit of Prior Art 1 is provided with a humidifying device inside a main body that forms the appearance of the indoor unit. And the humidifying device of Prior Art 1 stores the water of the drain fan in a water tank, wets an absorption member through the stored water, and has a structure in which the water absorbed by the absorption member is naturally evaporated.

[0005] The humidifying device of Prior Art 1 uses condensed water flowing out from a heat exchanger without using clean water. The water stored in the water tank contains a large amount of foreign substances separated from the surface of the heat exchanger. ​Lacquer had a problem in that the probability of mold or bacteria breeding in foreign substances was very high.

[0006] Moreover, since the humidifying device of Prior Art 1 evaporates water inside the main body, the evaporated water can adhere to the components or the inner wall inside the main body, causing problems such as mold or bacteria breeding inside the main body. There was this problem.

[0007] Even when the water evaporates inside the main body of the humidifying device of Prior Art 1 and the blower fan operates, the moisture evaporated by the blower fan cannot be completely discharged into the room. When the temperature of the indoor heat exchanger is low, there is a problem that it adheres to the surface of the indoor heat exchanger again. There was this problem.

[0008] Also, when the indoor temperature is low, the humidity of the indoor air is low. Therefore, in indoor conditions that require humidification, heating is generally carried out. Since the humidifying device of Prior Art 1 provides humidification by using the condensed water of the indoor heat exchanger, it can only provide humidification during cooling. During heating, since no condensed water is generated, there is a problem that it cannot provide humidification.

[0009] Korean Registered Utility Model Publication No. 20-0446245 (hereinafter referred to as Prior Art 2) discloses an air conditioner including a steam humidifier that boils water to generate steam and discharges the generated steam into the room to humidify the room. There is this disclosure.

[0010] Prior Art 2 includes a water tank, a water supply induction pipe, a heating heater pipe, and a steam discharge pipe, and has a structure that heats water through the heating heater pipe and discharges steam into the room through the steam discharge pipe. Prior Art 2 can supply water to the heating heater pipe by the pressure of the water stored in the water tank, but there is a problem in that it does not have a structure capable of draining the stored water. That is, As in the prior arts 1 and 2, a device that provides humidification stores water via a water tank and does not have a structure that can drain water when humidification is not required, so there is a problem that contamination by bacteria or mold occurs where water is stored during unused times.

[0011] This is because the humidified air discharged into the indoor space is discharged into the indoor space in a contaminated state Therefore, even if the function of controlling humidity is performed, it causes discomfort to the user or poses a hazard to the user's body and generates problems. Also, in the prior art 2 using the method of heating water, scale generated during heating is formed on the inside of the humidifying device and the surface of the heater, reducing the performance of the humidifying device and causing problems in shortening the lifespan of the humidifying device.

[0012] Also, in the prior art 2, since the size of the vapor particles contained in the generated humidified air is large formed, when the heated vapor is discharged without a member for separately flowing air, there is also a problem that a wide area of the indoor space cannot be humidified.

Table 1

[0293] ​​​​​​​​​​In the case of FIG. 22, the position where the water pipe 2314 is arranged on one side of the steam housing 2310 The voltage input to the drain pump 2710 and the drainage speed that can be grasped when the pipe diameter of the water pipe 2314 is different are shown in the graph. The arrangement of the water pipe 2314 in the above is Based on the front - rear direction of the steam housing 2310, the rear (Back) where the air intake part 2318 is arranged, the front (Front) where the steam discharge part 2316 is arranged, and the center (Center) formed between the front and the rear are used as references. However, the water pipe 2 314 is a part where the water inside the steam housing 2310 is drained, and is arranged at the lower end of the circumferential surface of the steam housing 2310 of the steam housing 2310 and the center (Center) formed between the front and the rear are used as references. However, the water pipe 2 314 is a part where the water inside the steam housing 2310 is drained, and is arranged at the lower end of the circumferential surface of the steam housing 2310 is arranged.

[0294] Table 1 above is a table that organizes the data grasped from the graph of FIG. 22

[0295] Referring to FIG. 22 and Table 1 above, it can be grasped that when the water pipe 2314 is arranged behind the steam housing 2310, the speed at which the water inside the steam housing 2310 is drained is faster This may be affected by the structure in which the air intake part 2318 is formed behind the steam housing 2310, applying pressure to the water inside the steam housing 2310 downward. Also, the structure in which the drain pump 2710 is arranged behind the steam housing 2310 may have an impact This may be affected by the structure in which the air intake part 2318 is formed behind the steam housing 2310, applying pressure to the water inside the steam housing 2310 downward. Also, the structure in which the drain pump 2710 is arranged behind the steam housing 2310 may have an impact 2310 may have an impact

[0296] Also, referring to FIG. 22 and Table 1 above, it can be grasped that the greater the voltage input to the drain pump 2710 by the water pipe 2314, the faster the speed at which the water inside the steam housing 2310 is drained However, the pipe diameter of the water pipe 2314 affects the drainage speed. It can be seen that it does not have a significant effect on speed.

[0297] In this embodiment, the water pipe 2314 is connected to the drain assembly from the water supply assembly 2200. The steam housing 2310 is disposed on one side of the periphery of the steam housing 2310 adjacent to the rib 2700. A first connecting pipe 2731 connected to the water supply assembly 2200 is connected to the drain assembly 270. 0 is formed longer than the third connecting pipe 2733 connected to the

[0298] In this embodiment, the first water level sensor 2360, the second water level sensor 2370, and and thermistor 2380 are disposed in the upper steam housing 2340. To this end, the upper steam housing 2340 is provided with the first water level sensor 2360. The first water level sensor installation unit 2342 and the second water level sensor 2370 are installed. A second water level sensor installation part 2344 is installed in the water level sensor 2340, and the thermistor 2380 is installed in the water level sensor 2344. A mister installation portion 2346 is formed.

[0299] The first water level sensor 2360, the second water level sensor 2370 and the thermistor 2380 , which protrudes from the upper surface of the steam housing 2310 into the inside of the steam housing 2310. The first water level sensor 2360, the second water level sensor 2370 and the The air intake 2318 may be surrounded by a first water level sensor 2380. 360, a second water level sensor 2370 and a thermistor 2380 are connected to the air intake 2318. It may be disposed between the steam discharge portion 2316.

[0300] Therefore, the air flowing in through the air intake 2318 reaches the first water level sensor 236 0. The structure of the second water level sensor 2370 and the thermistor 2380 can increase the area of the steam housing 2310 through which water flows upward on the upper side. That is, the air inlet 2318 flows through the structure of the first water level sensor 2360, the second water level sensor 2370, and the thermistor 2380 disposed between the air inlet 2318 and the steam discharge part 2316. This can have the effect of expanding the flow path of the air flowing upward on the upper side of the water present in the steam housing 2310, and the humidifying power of the air discharged to the steam discharge part 2316 can increase. The air inlet 2318 and the steam discharge part 2316 formed in the upper steam housing 2340 are formed with different heights. The steam discharge part 2316 and the air inlet 2318 form a height difference (SH), and the steam discharge part 2316 is disposed higher by the height difference ( SH) than the air inlet 2318.

[0301] The upper steam housing 2340 can form a recessed part 2317 in which the internal space bulges upward at the part where the steam discharge part 2316 is formed. The height at which the recessed part 231 7 is formed upward can form a height difference (SH) with the steam discharge part 2316 and the air inlet 2318.

[0302] The second water level sensor 2370 can be disposed on one side of the steam discharge part 2316 in which the recessed part 2317 of the upper steam housing 2340 is formed. The length by which the second water level sensor 237 0 protrudes downward into the internal space of the steam housing 2310 is the height (SH) from the air inlet 231 8 to the steam discharge part 2316 separated upward, and the second water level sensor ​ The height (AH) from the highest water level (WH) sensed by 2370 to the air intake portion 2318 separated upward can be added to form the length. That is, since the length formed by the submersion portion 2317 in the vertical direction can ensure that the protruding length of the second water level sensor 2370 is equal to or greater than a certain value, an existing water level sensor can be utilized to

[0303] sense the water level of the water existing inside the steam generator 2300. This is because the steam inside the upper steam housing 2340 forms a structure that can easily flow to the steam discharge portion 231 6. When the steam discharge portion 231 6 is formed higher than the air intake portion 2318, the steam with a low density can easily flow to the space below the steam discharge portion 2 316. 6. 6 is formed higher than the air intake portion 2318, the steam with a low density can easily flow to the space below the steam discharge portion 2 316.

[0304] The first water level sensor 2360 in the present embodiment is installed on the peripheral surface of the air intake portion 2318 to sense the low water level of the steam generator 230 0. The second water level sensor 2370 is installed around the steam discharge portion 2316 of the steam generator 2300 to sense the high water level.

[0305] Since the first water level sensor 2360 and the second water level sensor 2370 form a height difference, the lengths of the electrodes of the first water level sensor 2360 and the second water level sensor 2370 can be minimized.

[0306] The first water level sensor 2360 includes a first - 1 water level sensing portion 2361 and a first - 2 water level sensing portion 2362. The first - 1 water level sensing portion 2361 and the first - 2 water level sensing portion ​​​The lower ends of 2362 are arranged at the same height. The first-level water level sensing in this embodiment parts 2361 and the first-level-2 water level sensing part 2362 are electrodes. When water touches the first-level water level sensing part 2361 and the first-level-2 water level sensing part 2362, the control part senses this .

[0307] The first water level sensor 2360 is arranged on one side of the steam heater 2320 inside the steam housing 2310. In the steam housing 2310 according to this embodiment , a partition wall 235 9 is formed between the steam heater 2320 and the first water level sensor 2360. The partition wall 2359 can be formed to protrude upward from the bottom surface 2352a of the lower steam housing 2350. The partition wall 2359 is arranged between the first water level sensor 2360 and the steam heater 2320. Therefore, the first water level sensor 2360 is arranged between the partition wall 2359 and the peripheral surface of the lower steam housing 2350, and it can be prevented that the first water level sensor 2360 malfunctions due to the bubbles generated by the steam heater 2320. heater 2320. bubbles generated by the heater 2320 cause the first water level sensor 2360 to malfunction .

[0308] The lower ends of the first-level-1 water level sensing part 2361 and the first-level-2 water level sensing part 23 62 in this embodiment are the lowest water level (WL) for driving the steam generator 2300. That is, the lowest water level (W L) sensed by the first water level sensor 2360, which are the lower ends 2361a, 2362a of the first-level-1 water level sensing part 2361 and the first-level-2 water level sensing part 2362, can be set in consideration of the lowest water level at which the steam heater can operate and the water level at which malfunction due to the bubbles generated by the steam heater 2320 can be prevented. L) is the lowest water level at which the steam heater can operate and the water level at which malfunction due to the bubbles generated by the steam heater 2320 can be prevented.

[0309] When the lower ends 2361a, 2362a of the first water level sensor 2361 and the second water level sensor 2362 a. If the water level is lower than 2361a, 2362a, damage to the steam heater 2320 may occur. Therefore, if the water level is lower than the lower ends 2361a, 2362a of the first water level sensor 2361 and the second water level sensor 2362, the power supply to the steam heater 2320 is cut off.

[0310] In this embodiment, the second water level sensor 2370 uses an electrode that senses when water touches it. The lower end 2370a of the second water level sensor 2370 senses the maximum water level (WH) of the steam generator 2300. If the water level of the steam generator 2300 is higher than the lower end 2370a of the second water level sensor 2370, the water may boil over due to the operation of the steam heater 2320. When the water level touches the lower end 2370a of the second water level sensor 2370, the operation of the steam heater 2320 is stopped. 2320, the water may boil over. When the water level touches the lower end 2370a of the second water level sensor 2370, the operation of the steam heater 2320 is stopped.

[0311] The maximum water level (WH) is set at a height that takes into account the tilting of the indoor unit. That is, when the indoor unit tilts in any one direction, the water level inside the steam housing 2310 may be higher on one side. In this embodiment, when the indoor unit tilts three times in any one direction and the steam generator 2300 is operating at maximum, the maximum water level (WH) is set at a height where water does not overflow outside the steam housing 2310. 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 operation of the steam heater 2320 is stopped and the drain assembly 2700 is operated to drain the water inside the steam housing 2310.

[0312] ​​​​The proper water level of the steam generator 2300 is lower than the lower end 2370a of the second water level sensor 2370 and higher than the lower ends 2361a and 2362a of the first water level sensing portion 2361 and the second water level sensing portion 2362. In this embodiment, this is defined as the proper water level. The air intake portion 2318 can be formed at a set interval (AH) above the highest water level (WH) sensed by the second water level sensor 2370. The air inlet 2318a is disposed above the lower end 2370a of the second water level sensor 2370 that senses the highest water level (WH) inside the steam housing 2310. The set interval (AH) may be an interval considering the height at which the water stored inside the steam housing 2310 can vibrate in the vertical direction due to the flow of air flowing in from the air intake portion 2318. The water stored inside the steam housing 2310 due to the flow of air flowing in from the air intake portion 2318 can vibrate 3 mm or less in the vertical direction. The lower end 2380a of the thermistor 2380 is disposed within the proper water level. When the internal temperature of the steam generator 2300 rises above the set value, the thermistor 2380 senses this and stops the operation of the steam heater 2320. In this embodiment, this is defined as the proper water level.

[0313] The air intake portion 2318 can be formed at a set interval (AH) above the highest water level (WH) sensed by the second water level sensor 2370. The air inlet 2318a is disposed above the lower end 2370a of the second water level sensor 2370 that senses the highest water level (WH) inside the steam housing 2310. The set interval (AH) may be an interval considering the height at which the water stored inside the steam housing 2310 can vibrate in the vertical direction due to the flow of air flowing in from the air intake portion 2318. The water stored inside the steam housing 2310 due to the flow of air flowing in from the air intake portion 2318 can vibrate 3 mm or less in the vertical direction. To ensure a humidification amount above a certain level, it is advantageous for a large amount of air to flow into the inside of the steam housing 2310 and be discharged to the steam discharge portion 2316. Therefore, the larger the area of the air intake portion 2318, the more advantageous it is. Also, after the humidification operation ends, the steam housing To ensure a humidification amount above a certain level, it is advantageous for a large amount of air to flow into the inside of the steam housing 2310 and be discharged to the steam discharge portion 2316. Therefore, the larger the area of the air intake portion 2318, the more advantageous it is. Also, after the humidification operation ends, the steam housing

[0314] The lower end 2380a of the thermistor 2380 is disposed within the proper water level. When the internal temperature of the steam generator 2300 rises above the set value, the thermistor 2380 senses this and stops the operation of the steam heater 2320.

[0315] To ensure a humidification amount above a certain level, it is advantageous for a large amount of air to flow into the inside of the steam housing 2310 and be discharged to the steam discharge portion 2316. Therefore, the larger the area of the air intake portion 2318, the more advantageous it is. Also, after the humidification operation ends, the steam housing Even to quickly dry the interior of the using 2310, when a large amount of air flows into the interior of the steam housing 2310, the drying time is shortened. Therefore, the larger the area of the air intake part 2318 is , the more advantageous it is.

[0316] However, the area of the air inlet 2318a formed in the air intake part 2318 can be set in consideration of the size of the humidifying fan 2500. The area of the air inlet 2318a can be determined by the flow path cross-section of the humidifying fan housing 2530 that houses the humidifying fan 2500, and specifically, it can be set in consideration of the area of the second humidifying fan housing 2560 that guides the filtered air to the steam generator 23 00 by the operation of the humidifying impeller 2510. That is , in order for the flow velocity of the air flowing into the steam generator 2300 by the humidifying fan 2500 to meet the set level, the area of the air inlet 2318a can be set in consideration of the size of the humidifying fan 2500 so that the flow velocity of the air discharged through the second humidifying fan housing 2560 is maintained.

[0317] However, the size of the humidifying impeller 251 0 and the size of the humidifying fan housing 2530 of the humidifying fan 2500 arranged inside the base 130 can be limited. Therefore, the area of the air inlet 2318a can also be limited in consideration of the size of the humidifying impeller 2510 or the front of the second humidifying fan housing 2560.

[0318] As an embodiment, in order to dry the interior of the steam generator 2300, if the area of the air inlet 2318a is formed so that the flow velocity of the air discharged by the humidifying fan 2500 forms 0.65 CMM or more, the humidifying impeller arranged inside the base 130 ​ When the diameter of the rotor 2510 is 120 mm, the area of the air intake 2318a is 4500 m m 2 ~4700mm 2 can be formed.

[0319] In this embodiment, the air intake section 2318 is wider than the steam exhaust section 2316. According to the present embodiment, the air intake port 2318a formed in the air intake portion 2318 is The area is larger than the area of the steam discharge port 2316a formed in the steam discharge part 2316. The area of the steam outlet 2316a is larger than the area of the air inlet 2318a. If it is small, the flow rate of the humidified air flowing through the steam outlet 2316a must be ensured. can be done.

[0320] The flow rate of the air caused by the humidifying fan 2500 is Compared to the flow rate of air, the steam that flows through the steam housing 2310 and the steam outlet 2316a is In the case of the steam outlet 2316a, the flow rate of the moving air may be relatively slow. The air passing through the air intake port 2318a is formed at a distance from the fan 2500. The cross-sectional area of the flow path The steam suddenly flows through the inside of the large steam housing 2310 and into the steam outlet 2316a. Therefore, the flow velocity may be slower than that of the air inlet 2318a.

[0321] The flow rate of the air flowing through the steam outlet 2316a is determined by the air intake 231 The area of the steam outlet 2316a is set to be similar to the flow rate of the air flowing through the steam outlet 2316a. It can be formed narrower than the air intake port 2318a.

[0322] In one embodiment, in order to dry the interior of the steam generator 2300, the air flow rate discharged by the humidifier 2500 is made 0.65 CMM or more, and the area of the air intake port 2318a is formed to be 4600 mm When formed to be, the area of the steam discharge portion 2316 can be formed to be 2300 mm ~3067 mm 2 2 2 2 ~3067 mm 2 At this time, the height (AH) from the highest water level ( WH) to the air intake port 2318a can be formed to be 3 mm or more.

[0323] The area of the steam discharge port 2316a can be formed to be 1 / 2 to 2 / 3 the size of the area of the air intake port 2318a. The water pipe 2314 communicates with the inside of the steam housing 2310. Water in the water supply assembly 2300 can be supplied through the water pipe 2314. And the water discharged through the water pipe 2314 inside the steam housing 2310 can flow into the drain assembly 2700.

[0324]

[0324] The steam generator 2300 according to this embodiment is characterized in that one water pipe 2314 is used for both water supply and drainage. Generally, in the case of a device that generates steam, it is provided with both a pipe for supplying water and a pipe for discharging water.

[0325]

[0325] The water pipe 2314 is arranged horizontally. 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 side. The outer end of the water pipe 2314 protrudes further laterally from the side surface of the lower steam housing 2350.

[0326] The water pipe 2314 is connected to the chamber housing pipe 2214 and is arranged in the left - right direction. The water pipe 2314 in this embodiment is in the form of a hollow pipe. .

[0327] In the case of Fig. 23, while varying the pipe diameter of the water pipe 2314 and the arrangement of the water pipe 2314, when heating the water stored in the steam generator with the steam heater 2320, the first water supply passage formed in the connecting pipe 2731 and the temperature change of the water existing in the drainage passage formed in the third connecting pipe 2733 are shown in the drawing. The arrangement of the water pipe 2314 mentioned above is based on the front - rear direction of the steam housing 2310, with the rear ( Back) where the air intake part 2318 is arranged and the front (Front) where the steam discharge part 2316 is arranged as the reference. Looking at Fig. 23, when the water stored in the steam generator is heated by the steam heater 2320, compared with the drainage passage formed in the third connecting pipe 2733, a larger temperature change can be formed on the water supply passage formed in the first connecting pipe 2731. The first connecting pipe 273

[0328] 1 is formed to slope upward. As a flow path extending upward is formed, a part of the water heated inside the steam generator 2300 can flow upward, and a temperature change on the water supply passage can occur. When the water stored in the steam generator is heated by the steam heater 2320, the change in temperature on the water supply passage or the drainage passage is due to the heated water in the steam generator flowing backward into the water supply passage or the drainage passage. Therefore, the water pipe 2314 1 slopes upward and forms a flow path extending upward. As a result, a part of the water heated inside the steam generator 2300 can flow upward, and a temperature change on the water supply passage can occur. can occur.

[0329] When the water stored in the steam generator is heated by the steam heater 2320, the change in temperature on the water supply passage or the drainage passage is due to the heated water in the steam generator flowing backward into the water supply passage or the drainage passage. Therefore, it is due to the heated water in the steam generator flowing backward into the water supply passage or the drainage passage. Thus, the By adjusting the arrangement and pipe diameter, the water heated by the steam generator 2300 is fed into the supply water flow path and the exhaust It is preferable to adopt a diameter and arrangement of water pipes that do not allow backflow through the water flow path.

[0330] The smaller the diameter of the water pipe 2314, the less temperature change occurs in the water supply flow path and the drainage flow path. It can be seen from FIG. 23 that the water pipe 2314 has a pipe diameter of Φ9 When the pipe diameter is Φ7, there is a slight temperature change in the water supply and drainage passages. The smaller the pipe diameter, the greater the flow resistance, so the The water flowing from the room generator 2300 to the water pipe 2314 is reduced, and the water supply Small temperature variations over the flow path or drainage path may occur.

[0331] When the water pipe 2314 is disposed at the rear of the steam housing 2310, the water supply flow path It can also be seen that a small temperature change occurs in the drainage flow path. When the water pipe 2314 is located in front of the steam housing 2310, the steam is more efficiently drawn through the water pipe 2314. When the cooling fan is disposed behind the housing 2310, there is little temperature change in the water supply passage and the drain passage. The water that flows back from the steam generator 2300 is The water can flow into the water supply passage extending to the side of the steam housing 2310, and is disposed at the rear of the steam housing 2310. When the water supply assembly 2200 is inserted into the water supply passage 2201, the water supply passage 2201 is formed as the water supply assembly 2200 is moved away from the water supply assembly 2200. The length of the first connecting pipe 2731 is increased. The longer the length of the water supply flow path, the Because of the large resistance, steam flows from the steam generator 2300 to the water pipe 2314. Less moving water is produced and less temperature change can be produced on the water supply or drainage lines. Also, the water pipe 2314 according to the present invention is connected to the first connecting pipe 2 731 and the third connecting pipe 2733 via the three-way pipe 2735, so that water flowing back through the water pipe 2314 flows into the first connecting pipe 2731 in which the supply flow path is formed. Thus, the movement of water flowing back into the third connecting pipe 2733 connected to the drain pump 2710 can be blocked. That is, the first connecting pipe 2731, the third connecting pipe 2733, and the water pipe 2314 are connected via the three-way pipe 2735, so that the backflow can be minimized in the third connecting pipe 2733 in which the drainage flow path is formed, and the temperature change on the drainage flow path can be minimized. Also, by arranging the water pipe 2314 behind the steam housing 2310, the backflow can be minimized in the first connecting pipe 2731 in which the water supply flow path is formed, and the temperature change on the water supply flow path can be minimized. The water pipe 2314 is arranged on the rear side with reference to the front-rear direction of the steam housing 2310. The water pipe 2314 is preferably arranged close to the drain assembly. The water pipe 2314 is effective in suppressing the temperature rise of the drain assembly 2700. The water pipe 2314 is arranged closer to the drain assembly 2700 than the water tank 2100 or the water supply assembly 2200 so as to prevent the water inside the steam generator 2300 from flowing back in the direction of the water tank 2100. The water pipe 2314 is connected to the water supply assembly 2200 and the drain assembly 2700 via the water connecting pipe 2730. Referring to FIG. 16, the water connecting pipe 2730 is the water supply assembly The water pipe 2314 is arranged on the rear side with reference to the front-rear direction of the steam housing 2310. The water pipe 2314 is preferably arranged close to the drain assembly. The water pipe 2314 is effective in suppressing the temperature rise of the drain assembly 2700. It can be done.

It is effective.

[0333] The water pipe 2314 is arranged closer to the drain assembly 2700 than the water tank 2100 or the water supply assembly 2200 so as to prevent the water inside the steam generator 2300 from flowing back in the direction of the water tank 2100. The water pipe 2314 is arranged closer to the drain assembly 2700 than the water tank 2100 or the water supply assembly 2200 so as to prevent the water inside the steam generator 2300 from flowing back in the direction of the water tank 2100. The water pipe 2314 is arranged closer to the drain assembly 2700 than the water tank 2100 or the water supply assembly 2200 so as to prevent the water inside the steam generator 2300 from flowing back in the direction of the water tank 2100.

[0334] The water pipe 2314 is connected to the water supply assembly 2200 and the drain assembly 2700 via the water connecting pipe 2730. Referring to FIG. 16, the water connecting pipe 2730 is the water supply assembly Referring to FIG. 16, the water connecting pipe 2730 is the water supply assembly a first connecting pipe 2731 connected to the drain assembly 2700; a third connecting pipe 2733 connected to the water pipe 2314; a second connecting pipe 2732 connected to the water pipe 2314; The three connecting pipes 2731, 2732 and 2733 are connected to each other. and a directional pipe 2735.

The steam generator 2300 and the water supply assembly 2200 are connected to prevent A first connecting pipe 2731 connects the steam generator 2300 to the drain assembly 2700. The flow resistance is greater than that of the third connecting pipe 2733 which connects the first connecting pipe 2731 and the second connecting pipe 2732 .

[0336] The first connecting pipe 2731 according to this embodiment has a larger flow resistance than the third connecting pipe 2733. In order to prevent this, the first connecting pipe 273 may be formed longer than the third connecting pipe 2733. The first and third connecting pipes 2733 may have similar pipe diameters. The length (D1) of the connecting tube 2731 is 1.5 to 2 times the length (D2) of the third connecting tube 2733. The first connecting pipe 2731 may be formed to have a length 5 times that of the third connecting pipe 2733. In order to form a large connection, the length (D1) of the first connecting pipe 2731 is set to be longer than that of the third connecting pipe 27 It is preferable that the length (D2) of the first chain is 1.5 times longer than the length of the second chain. If the length of the first connecting pipe 2731 becomes too long, the water contained inside the first connecting pipe 2731 may become too large. Since the amount of the liquid increases, the length (D1) of the first connecting pipe 2731 is shorter than the length (D2) of the third connecting pipe 2733. It is preferable that it is formed shorter than 2.5 times (D2).

[0351] ​​​​​​​​​​​The first heater unit 2321 and the second heater unit 2322 having different capacities are independent and are operated to adjust the amount of humidification discharged to the outside. That is, compared with when only the first heater unit 2321 is operated, the amount of humidification when only the second heater unit 2322 is operated can be increased. Therefore, by adjusting the operations of the first heater unit 2321 and the second heater unit 2322, the amount of humidification discharged can be adjusted. Also, for an even greater amount of humidification, it is also possible to operate the first heater unit 2321 and the second heater unit 2322 simultaneously.

[0353] During normal operation of the steam generator 2300, the internal temperature of 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 senses this and shuts off the overheating of the steam generator 2300. When the steam generator 2300 overheats, the second water level sensor 2370 can be operated at around 140 degrees.

[0354] If the second water level sensor 2370 cannot sense overheating, the thermistor 2380 senses the overheating of the steam generator 2300, and the thermistor 2380 senses a temperature range of around 150 to 180 degrees. The thermistor 2380 in this embodiment senses 1 67 degrees or more.

[0355] ​​ Even after power control by the thermistor 2380, inside the steam housing 2310 if the temperature (250 degrees Celsius in this embodiment) rises, the fuse cuts off the power supply to the steam heater 2320.

[0384] The water pipe 2314 according to this embodiment can be formed on the circumferential surface of the steam housing 2310 arranged on the rear right side with reference to the horizontal line (LR) and the vertical line (LC). Therefore, the water pipe 2 314 is arranged at a distance from the water supply assembly 2300 arranged on the front side with reference to the horizontal line (LR), and is arranged at a short distance from the drain assembly 2700 arranged on the rear side with reference to the horizontal line (LR). The water pipe 2314 can be arranged on the circumferential surface of the steam housing 2310 below the first region (I) and the second region (II) which are the regions where the air intake part 2318 is mainly arranged. The water pipe 2314 is arranged at a distance from the water supply assembly 2300 and is arranged in the rear region where the air intake part 2318 is mainly arranged, so that the water existing in the steam housing 2310 can be prevented from flowing back into the water pipe 2314.

[0385] When general air that is not filtered air flows into the inside of the steam housing 2310, the inside of the steam housing 2310 has a very high possibility of breeding mold and the like.

[0386] In this embodiment, since the air supplied into the inside of the steam housing 2310 is limited to filtered air, when the steam generator 2300 does not operate, the inside can be minimized from being contaminated by bacteria or mold and the like. It can be minimized that the inside is contaminated by bacteria or mold and the like.

[0387] In the present embodiment, for the steam generator 2300, the air flow of the humidifying fan 2500 is supplied to the inside to push the steam out of the steam housing 2310, so that the flow pressure of the steam can be maximized.

[0388] Different from this embodiment, when the structure is such that the humidifying fan sucks in the steam outside the steam housing, the internal steam of the steam housing may not be smoothly discharged.

[0389] If the steam generated by the steam generator 2300 does not quickly flow to the side discharge ports 301 and 30 2, condensation may occur during the movement process of the steam.

FIG. 25 is the operation cycle of the drain pump according to an embodiment of the present invention. ​​​​​​​Compare the internal temperature and heat transfer rate of the heater obtained thereby with the internal temperature and heat transfer rate of the heater in the washing machine This is the graph shown by

[0393] <Configuration of the drain assembly> The drain assembly 2700 is disposed on the base 130 and drains the water of the water supply assembly 2 200 and the steam generator 2300, a drain pump 2710, and the Connected to the drain pump 2710, the water pumped by the drain pump 2710 is Guided outside the indoor unit described above, a drain hose 2720, and the chamber of the water supply assembly 2200 Number housing pipe 2214, water pipe 2314 of the steam generator 2300 and A water connection pipe 2730 that connects the drain pump 2710 to allow water to flow is included.

[0394] Since the configuration of the drain pump 2710 is a general device for those skilled in the art, the description of its operation Is omitted. The drain pump 2710 is connected to the water connection pipe 2730 A drain inlet 2714 and a drain outlet 2712 connected to the drain hose 2720 are included.

[0395] The drain inlet 2714 is disposed horizontally and protrudes toward the steam generator 2300 in the present embodiment. The drain outlet 2712 protrudes upward.

[0396] In the present embodiment, the water in the water supply assembly 2200, the steam generator 2300, and the drain pump 2710 is moved by the weight of the water. Therefore, the arrangement of the drain pump 2710 is arranged to satisfy this. Therefore, the drain pump 2710 Is arranged. and being disposed lower than the chamber housing pipe 2214 and the water pipe 2314 is preferred.

[0397] Since the water in the water supply assembly 2200 and the steam generator 2300 also moves by the weight of the water, the water pipe 2314 is preferably disposed lower than the chamber housing pipe 2214. is preferred.

[0398] With such an arrangement, among these three, the chamber housing pipe 2214 is disposed highest, the drain pump 2710 is disposed lowest, and the water pipe 2314 is disposed at a height between the chamber housing pipe 2214 and the drain pump 2710. .

[0399] The water supply assembly 2200, the steam generator 2300, and the drain pump 27 10 are all disposed on the base 130 of the cabinet assembly 100. To form the height difference described above, the base 130 forms a height difference.

[0400] In the present embodiment, the base 130 is formed with a drain pump installation portion 133 that is recessed downward.

[0401] The base 130 includes a flat base top wall 131 and a drain pump installation portion 133 that is recessed downward from the base top wall 131.

[0402] The base top wall 131 is positioned higher than the drain pump installation portion 133. .

[0403] The water connection pipe 2730 is a first one that is connected to the chamber housing pipe 2214. The connecting pipe 2731, the second connecting pipe 2732 connected to the water pipe 2314, and the third connecting pipe 2733 connected to the drain inlet 2714, and the first connecting pipe 273 1, the second connecting pipe 2732 and the three-way pipe 2735 connected to the third connecting pipe 2733 are included.

[0404] The three-way pipe 2735 may be a T-shaped pipe or a Y-shaped pipe. In this embodiment, a T-shaped pipe is used to minimize the installation space.

[0405] One end of the first connecting pipe 2731 is coupled to the chamber housing pipe 2214, and the other end is coupled to the three-way pipe 2735. Different from this embodiment, a valve is installed in the first connecting pipe 2731, and the installed valve can interrupt the flow of the first connecting pipe 2731.

[0406] One end of the second connecting 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 third connecting pipe 2733. When the scale generated by the steam generator 2300 flows into the drain pump 2710, it may cause a risk of poor drainage. The mesh filter may be formed to have a size capable of filtering scale lumps of 0.8 mm or more. The mesh filter filters the scale generated by the operation of the steam generator and blocks the scale from flowing into the drain pump 2710.

[0407] One end of the third connecting pipe 2733 is the drain inlet of the drain pump 2710 It is coupled to 2714, and the other end is coupled to the three-way pipe 2735.

[0408] Regarding the materials of the first connecting pipe 2731, the second connecting pipe 2732, and the third connecting pipe 2733 There are no particular restrictions, but in this embodiment, it is made of a synthetic resin material for easy assembly and is manufactured.

[0409] Here, since high-temperature water can flow into the second connecting pipe 2732, it is formed of a heat-resistant material (in this embodiment, EDPM) that can cover the temperature range of the steam generator 2300 and is preferably formed. At least the second connecting pipe 2732 is formed of a material that does not deform with respect to the temperature (216 degrees Celsius) before the heater fuse operates. Preferably, it is formed of a material that does not deform with respect to the temperature (216 degrees Celsius) before the heater fuse operates. Preferably, it is formed of a material that does not deform with respect to the temperature (216 degrees Celsius) before the heater fuse operates.

[0410] Preferably, the entire water connecting pipe 2730 is formed of a material that does not deform with respect to the temperature ( 216 degrees Celsius) before the heater fuse operates. The heater fuse according to this embodiment can set the cut-off temperature to 216 °C.

[0411] When the steam generator 2300 operates, even in a normal case, the water inside the steam generator 2300 can rise above 100 degrees. At this time, when there are a pipe for supplying water and a pipe for discharging water respectively, the pipe for supplying water is connected to the water tank and therefore has a slow temperature rise, but since only a small amount of water is stored in the pipe connected to the drain pump 2710, there is a problem that it rises to a temperature similar to that inside the steam generator 2300 and therefore has a slow temperature rise, but since only a small amount of water is stored in the pipe connected to the drain pump 2710, there is a problem that it rises to a temperature similar to that inside the steam generator 2300 and therefore has a slow temperature rise, but since only a small amount of water is stored in the pipe connected to the drain pump 2710, there is a problem that it rises to a temperature similar to that inside the steam generator 2300 and therefore has a slow temperature rise, but since only a small amount of water is stored in the pipe connected to the drain pump 2710, there is a problem that it rises to a temperature similar to that inside the steam generator 2300 and therefore has a slow temperature rise, but since only a small amount of water is stored in the pipe connected to the drain pump 2710, there is a problem that it rises to a temperature similar to that inside the steam generator 2300

[0412] When the water temperature of the pipe connected to the drain pump rises, the drain pump may be damaged. It is possible.

[0413] In this embodiment, to prevent this, the water of the steam generator 2300 and the water of the water supply assembly 2200 can be mixed by the three-way pipe 2735, and the temperature rise of the third connecting pipe 2733 can be suppressed by the mixed water. The water of the steam generator 2300 and the water of the water supply assembly 2200 can be mixed, and the temperature rise of the third connecting pipe 2733 can be suppressed by the mixed water. Even if the water temperature on the side of the second connecting pipe 2732 rises to 100 degrees Celsius or more, the water on the side of the first connecting pipe 2731 forms normal temperature. Therefore, the high-temperature water and the normal-temperature water are mixed by the three-way pipe 2735 to suppress the rise in water temperature.

[0414] Since the water on the side of the first connecting pipe 2731 is supplied with water from the water supply assembly 2200 side, the temperature rise can be suppressed through convection. Even if the water temperature on the side of the second connecting pipe 2732 rises to 100 degrees Celsius or more, the water on the side of the first connecting pipe 2731 forms normal temperature. Therefore, the high-temperature water and the normal-temperature water are mixed by the three-way pipe 2735 to suppress the rise in water temperature. Even if the water temperature on the side of the second connecting pipe 2732 rises to 100 degrees Celsius or more, the water on the side of the first connecting pipe 2731 forms normal temperature. Therefore, the high-temperature water and the normal-temperature water are mixed by the three-way pipe 2735 to suppress the rise in water temperature.

[0415] Since the water on the side of the first connecting pipe 2731 is supplied with water from the water supply assembly 2200 side, the temperature rise can be suppressed through convection. Since the water on the side of the first connecting pipe 2731 is supplied with water from the water supply assembly 2200 side, the temperature rise can be suppressed through convection.

[0416] For example, after the operation of the steam generator 2300, when the drain pump 2710 operates with the water inside the steam housing 2310 being at a high temperature, the high-temperature water drained by the second connecting pipe 2732 and the normal-temperature water drained by the first connecting pipe 2731 are mixed by the three-way pipe 2735, and the temperature of the mixed water can drop to at least 70 degrees Celsius or less. For example, after the operation of the steam generator 2300, when the drain pump 2710 operates with the water inside the steam housing 2310 being at a high temperature, the high-temperature water drained by the second connecting pipe 2732 and the normal-temperature water drained by the first connecting pipe 2731 are mixed by the three-way pipe 2735, and the temperature of the mixed water can drop to at least 70 degrees Celsius or less. For example, after the operation of the steam generator 2300, when the drain pump 2710 operates with the water inside the steam housing 2310 being at a high temperature, the high-temperature water drained by the second connecting pipe 2732 and the normal-temperature water drained by the first connecting pipe 2731 are mixed by the three-way pipe 2735, and the temperature of the mixed water can drop to at least 70 degrees Celsius or less. For example, after the operation of the steam generator 2300, when the drain pump 2710 operates with the water inside the steam housing 2310 being at a high temperature, the high-temperature water drained by the second connecting pipe 2732 and the normal-temperature water drained by the first connecting pipe 2731 are mixed by the three-way pipe 2735, and the temperature of the mixed water can drop to at least 70 degrees Celsius or less. It can drop.

[0417] In this embodiment, when draining through the water connecting pipe 2730, the water temperature flowing through the drain pump 2710 can be formed between 30 degrees and 50 degrees Celsius. In this embodiment, when draining through the water connecting pipe 2730, the water temperature flowing through the drain pump 2710 can be formed between 30 degrees and 50 degrees Celsius.

[0418] In this embodiment, when the drain pump 2710 operates, the steam housing 231 Not only the water stored inside 0, but also the water tank 2100 and the water supply assembly 220 has the feature that all the water stored in 0 is also drained.

[0419] The water used in the humidification assembly 2000 is used for indoor humidification, so there is a risk of bacteria breeding as time passes. Therefore, when not used for a predetermined period (24 hours), not only the water tank 2100 and the water supply assembly 2200, but also the water stored in the steam housing 2310 is all drained, and the entire humidification assembly 2000 can be controlled to be dried.

[0420] The water used in the humidification assembly 2000 is heated by the steam generator 2300 and then used. Therefore, 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 can act as a factor that prevents the heat generated by the steam heater 2320 from being transferred to the water stored inside the steam housing 2310. Therefore, it is preferable to periodically operate the drain assembly 2700 so as to minimize the generation of scale on the surface of the steam heater 2320 or inside the steam housing 2310. That is, as described above, when the humidification assembly 2000 is not used for a predetermined period (one day), it is preferable to drain all the water stored in the water tank 2100, the water supply assembly 220 0, and of course, the water stored in the steam housing 2310. 0, and of course, the water stored in the steam housing 2310.

[0421] Referring to FIG. 24, depending on the operation presence or absence and the operation cycle of the drain assembly 2700 according to the present embodiment, the steam heater 2320 heats the water inside the steam housing 2310 It is possible to grasp the change in the temperature of the steam heater 2320 for this purpose. That is, When the drain assembly 2700 operates at a cycle of once every three days, compared with the case where the drain assembly does not operate, the amount of scale generated is significantly reduced, and thereby it is possible to grasp that the temperature of the steam heater 232 0 for heating the water inside the steam housing 2310 decreases.

[0422] 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 the generation of scale is formed at 207.6 degrees when the drain assembly is not operated, and when the drain assembly 2700 is operated at a cycle of once every three days, it can be seen that the internal temperature of the steam heater 2320 is formed at 192.4 degrees. Although not shown in the drawings, when the drain assembly 2700 is operated at a cycle of once a day in the same manner, the internal temperature of the steam heater 2320 is formed at 185.9 degrees, and to minimize the generation of scale on the surface of the steam heater 2320 or inside the steam housing 2310, it can be seen that it is preferable to set the operation cycle of the drain assembly 2700 short. .

[0423] The heater fuse according to this embodiment sets the cut-off temperature to 216 °C, and even when the drain assembly 2700 does not operate periodically, the heater fuse does not blow during the use of the air conditioner for 10 years or more, and the steam heater 2320 can have the durability to operate.

[0424] Referring to FIG. 25, the presence or absence of operation and the operation ​​​​​The presence or absence of scale generation varies depending on the cycle. That is, when the drain assembly 2700 operates once every three days compared to the case where the drain assembly does not operate, the amount of scale generation is significantly reduced, and it can be understood that the heat transfer rate of the steam heater 2320 is also increased, and the internal temperature of the steam heater 2320 can be kept low.

[0425] Also, 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 601 W when the drain assembly does not operate, and when the drain assembly 2700 operates once every three days in one cycle, the predicted value of the heat transfer rate is formed as 624 W It can be seen. Also, although not shown in the drawings, when the drain assembly 2700 operates once a day in the same manner in one cycle, the predicted value of the heat transfer rate is formed as 631 W and it can be seen that it is preferable to set the operating cycle of the drain assembly 2700 short so as to minimize the generation of scale on the surface of the steam heater 2320 or inside the steam housing 2310.

[0426] When the drain pump 2710 operates, the water on the side of the third connecting pipe 2733 is drained Since one end of the third connecting pipe 2733 connected to the drain inlet 2714 is arranged lowest the water in the water tank 2100 and the water supply assembly 2200 flows through the first connecting pipe 2731 and the three-way pipe 2735 to the third connecting pipe 2733 due to the potential energy of the water.

[0427] Similarly, the water in the steam housing 2310 flows through the second ​​​​flows through the connecting pipes 2732 and the three-way pipe 2735 to the third connecting pipe 2733. .

[0428] In this way, the structure of the water connecting pipe 2730 not only suppresses the temperature rise of the steam generator 2300, but also easily realizes the overall drainage of the humidifying assembly 2000. It can be achieved.

[0429] <<Configuration of Steam Guide>> The steam guide 2400 supplies the steam of the steam generator 2300 to the discharge flow path. The discharge flow path includes an air flow path flowed by the long-distance fan assembly 400 and an air flow path flowed by the short-distance fan assembly.

[0430] In this embodiment, the discharge flow path is arranged in the cabinet assembly 100 and is defined until the air passing through the filter assembly 600 is discharged outside the cabinet assembly 100.

[0431] 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 internal air of the cabinet assembly 100. The steam guide 2400 may be in the form of a pipe or a duct.

[0432] The steam guide 2400 is coupled to the steam generator 2300, a main steam guide 2450 provided with humidified air of the steam generator 2300, and coupled to the main steam guide 2450 and supplied through the main steam guide 2450. ​A first branch guide 2410 that guides a part of the given humidified air to the first side discharge port 301 10, and coupled to the main steam guide 2450, the main steam guide 24 50, and a second branch guide 2420 that guides the other of the humidified air supplied through the second branch guide 2420 to the second side discharge port 302 is assembled with the first branch guide 2410, and is disposed at the first side discharge port 301, and humidified air supplied through the first branch guide 2410 is discharged to the first side discharge port 301 by a first diffuser 2430, and is assembled with the second branch guide 2420, and is disposed at the second side discharge port 302, and the humidified air supplied through the second branch guide 2420 is discharged to the second side discharge port 302 by a second diffuser 2440.

[0433] Differing from this embodiment, the first branch guide 2410 and the second branch guide 2420 can be directly coupled to the steam generator 2300. In this case, the steam generator 2300 has respective steam discharge portions to which the first branch guide 2410 and the second branch guide 2420 are coupled.

[0434] Also, differing from this embodiment, only one branch guide can be disposed, and a structure in which the one branch guide is coupled to one diffuser can be provided. In this case, the one diffuser can be disposed at only one of the first side discharge port or the second side discharge port.

[0435] Although the diffuser in this embodiment is disposed at the side discharge port, it may be installed at the front discharge port. That is, the installation position of the diffuser is not limited to the side discharge port. ​​​​​​​​​

[0436] The main stream guide 2450 in this embodiment is formed in a duct shape. The main stream guide 2450 guides air from the lower side to the upper side. The main stream guide 2450 supplies the air (the air in which steam and filtered air are mixed) supplied from the steam generator 2300 to the first branch guide 2410 and the second branch guide 2 420.

[0437] The air (the air in which steam and filtered air are mixed) supplied from the steam generator 2300 is branched into the first branch guide 2410 and the second branch guide 2420 in the main stream guide 2450.

[0438] The lower end of the main stream guide 2450 is coupled to the steam discharge portion 2316 of the steam housing 2310. The upper end of the main stream guide 2450 is coupled to the first branch guide 2410 and the second branch guide 2420.

[0439] The lower side of the main stream guide 2450 is open. On the upper side of the main stream guide 2450, there are a first guide coupling portion 2451 where the first branch guide 2410 is assembled and a second guide coupling portion 24 52 where the second branch guide 2420 is assembled.

[0440] The first guide coupling portion 2451 and the second guide coupling portion 2452 penetrate in the vertical direction. The first guide coupling portion 2451 and the second guide coupling portion 2452 in this embodiment are formed in a pipe shape.

[0441] ​​​​​​​The first branch guide 2410 is formed in a pipe shape corresponding to the cross-sectional plane of the first guide coupling portion 2451. The second branch guide 2420 is formed in a pipe shape corresponding to the cross-sectional plane of the second guide coupling portion 2451. Since the main stream guide 2450 in the present embodiment is disposed while being biased to one side (left side) in the front view of the cabinet assembly 100, the first branch guide 2410 and the second branch guide 2420 are formed with different lengths.

[0442] It is preferable that air is evenly supplied to the first branch guide 2410 and the second branch guide 2420. In the present embodiment, the pipe diameters of the first branch guide 2410 and the second branch guide 2420 are manufactured differently, so that the flow rates of the first branch guide 2410 and the second branch guide 2420 can be made uniform.

[0443] For example, the pipe diameter of the steam guide with a short length can be made smaller, and the pipe diameter of the steam guide with a long length can be made larger, so that the flow rates can be made uniform. The first diffuser 2430 and the second diffuser 2440 are symmetric in the left-right direction. The first diffuser 2430 is assembled with the first branch guide 2410 and is disposed at the first side discharge port 301. The first diffuser 2430 discharges the air supplied together with the steam through the first branch guide 2410 to the first side discharge port 301.

[0444]

[0445]

[0446]

[0447] ​​​​​​​​The first diffuser 2430 stores and discharges the filtered air containing the steam discharged from the first side discharge port 301. When the flow velocity or pressure of the air discharged from the first diffuser 2430 is greater than the flow velocity and pressure of the air discharged to the first side discharge port 301 by the short-distance fan assembly, the air discharged from the first diffuser 2430 acts as a resistance to the air discharged to the first side discharge port 301 by the short-distance fan assembly, making it impossible for the air discharged from the first side discharge port 301 to flow smoothly in the indoor space. Therefore, the flow velocity and pressure of the air discharged through the first side discharge port 301 are formed to be the same as or greater than the flow velocity or pressure of the air discharged from the first diffuser 2430. The air discharged from the first diffuser 2430 stores and discharges the filtered air containing the steam discharged from the first side discharge port 301. When the flow velocity or pressure of the air discharged from the first diffuser 2430 is greater than the flow velocity and pressure of the air discharged to the first side discharge port 301 by the short-distance fan assembly, the air discharged from the first diffuser 2430 acts as a resistance to the air discharged to the first side discharge port 301 by the short-distance fan assembly, making it impossible for the air discharged from the first side discharge port 301 to flow smoothly in the indoor space. Therefore, the air discharged from the first diffuser 2430 acts as a resistance to the air discharged to the first side discharge port 301 by the short-distance fan assembly, making it impossible for the air discharged from the first side discharge port 301 to flow smoothly in the indoor space. Therefore, the air discharged from the first diffuser 2430 acts as a resistance to the air discharged to the first side discharge port 301 by the short-distance fan assembly, making it impossible for the air discharged from the first side discharge port 301 to flow smoothly in the indoor space. Therefore, the air discharged from the first diffuser 2430 acts as a resistance to the air discharged to the first side discharge port 301 by the short-distance fan assembly, making it impossible for the air discharged from the first side discharge port 301 to flow smoothly in the indoor space. Therefore, the flow velocity and pressure of the air discharged through the first side discharge port 301 are formed to be the same as or greater than the flow velocity or pressure of the air discharged from the first diffuser 2430. Therefore, the flow velocity and pressure of the air discharged through the first side discharge port 301 are formed to be the same as or greater than the flow velocity or pressure of the air discharged from the first diffuser 2430.

[0448] The air discharged from the first side discharge port 301 can further diffuse the steam discharged from the first diffuser 2430. The second diffuser 2440 operates on the same principle. The air discharged from the first side discharge port 301 can further diffuse the steam discharged from the first diffuser 2430. The second diffuser 2440 operates on the same principle. The air discharged from the first side discharge port 301 can further diffuse the steam discharged from the first diffuser 2430. The second diffuser 2440 operates on the same principle.

[0449] Since the flow velocity and pressure of the air discharged from the side discharge ports 301 and 302 are formed to be greater than the flow velocity and pressure of the air discharged from the diffusers 2430 and 2440, condensation around the side discharge ports 301 and 302 due to steam can be minimized. Since the flow velocity and pressure of the air discharged from the side discharge ports 301 and 302 are formed to be greater than the flow velocity and pressure of the air discharged from the diffusers 2430 and 2440, condensation around the side discharge ports 301 and 302 due to steam can be minimized. Since the flow velocity and pressure of the air discharged from the side discharge ports 301 and 302 are formed to be greater than the flow velocity and pressure of the air discharged from the diffusers 2430 and 2440, condensation around the side discharge ports 301 and 302 due to steam can be minimized.

[0450] The second diffuser 2440 is assembled with the second branch guide 2420 and is disposed at the second side discharge port 302. The second diffuser 2440 discharges the air supplied together with the steam through the second branch guide 2420 to the second side discharge port 302. The second diffuser 2440 is assembled with the second branch guide 2420 and is disposed at the second side discharge port 302. The second diffuser 2440 discharges the air supplied together with the steam through the second branch guide 2420 to the second side discharge port 302. The second diffuser 2440 discharges the air supplied together with the steam through the second branch guide 2420 to the second side discharge port 302.

[0451] The first diffuser 2430 and the second diffuser 2440 have the same structure. Therefore, the first diffuser 2430 will be described as an example. For the sake of explanation, the first diffuser 2430 will be described as an example.

[0452] The first diffuser 2430 discharges air to the side discharge port supplied with steam on the lower side. It discharges to the side discharge port supplied with steam on the lower side.

[0453] The diffuser (the first diffuser and the second diffuser in this embodiment) has a space formed inside and is a diffuser housing 2460 with one side (the lower side in this embodiment) opened. The diffuser outlets 2431 and 2441 are formed to penetrate the diffuser housing 2460.

The diffuser inlets 2433 and 2443 are arranged outside the diffuser housing 2460, are arranged in the diffuser housing 2460, and are assembled with the steam guides 2420 and 2430. It includes the diffuser housing 2460 with a space formed inside and opened on one side (the lower side in this embodiment), the diffuser outlets 2431 and 2441 formed to penetrate the diffuser housing 2460, and the diffuser inlets 2433 and 2443 arranged outside the diffuser housing 2460, arranged in the diffuser housing 2460, and assembled with the steam guides 2420 and 2430.

[0454] For the convenience of explanation, when it is necessary to distinguish the diffuser outlets of the first diffuser 2430 and the second diffuser 2440, they are defined as the first diffuser outlet 2431 and the second diffuser outlet 2441. Similarly, when it is necessary to distinguish the diffuser inlets of the first diffuser 2430 and the second diffuser 2440, they are defined as the first diffuser inlet 2433 and the second diffuser inlet 2443.

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

Similarly, when it is necessary to distinguish the diffuser inlets of the first diffuser 2430 and the second diffuser 2440, they are defined as the first diffuser inlet 2433 and the second diffuser inlet 2443.

[0455] The diffuser outlet 2431 is formed in a slit shape. The diffuser The outlet 2431 extends long in the vertical direction. The diffuser outlet 24 31 can be arranged in a plurality in the length direction of the diffuser housing 2460. The diff user outlet 2431 is arranged facing the left or right side.

[0456] The diffuser outlet 2431 is arranged near the side discharge ports 301, 302 of the cabinet assembly 100.

[0457] The first diffuser outlet 2431 is arranged facing the left side of the cabinet assembly 100, and the second diffuser outlet 2441 is arranged facing the right side of the cabinet assembly 100.

[0458] The diffuser outlet 2431 in this embodiment is arranged in front of the side discharge ports 301, 302, and the humidified air can be made to flow farther by the flow of the air discharged from the side discharge ports 301, 302.

[0459] A diffuser space is formed inside the diffuser housing 2460. The diffuser space communicates with the diffuser inlet 2433 and the diffuser outlet 2431. The diffuser space extends long in the vertical direction. In a plan view, the inside of the diffuser space is wide and the outside is narrow.

[0460] The diffuser inlet 2433 in this embodiment is formed in a pipe shape.

[0461] The diffuser inlet 2433 is inserted inside the steam guide 2420. ​​​​​This is to prevent the condensed water generated inside the diffuser housing 2460 from leaking to the outside. Specifically, it is to prevent the condensed water generated inside the diffuser housing 2460 from leaking to the outside. For this purpose.

[0462] The condensed water placed inside the diffuser housing 2460 flows downward due to its own weight, moves to the steam guide 2420 through the diffuser inlet 2433, and can be recovered by the steam generator 2300 via the main steam guide 2450 after that. It is possible.

[0463] When the humidifying fan 2500 is operating, the condensed water inside the diffuser housing 2460 can naturally evaporate due to the flowing air. When the humidifying fan 2500 is not operating, the condensed water placed inside the diffuser housing 2460 can be recovered by the steam generator 2300, or can be discharged to the outside via the drain assembly 2700. It is possible.

[0464] The humidifying assembly 2000 according to this embodiment does not only depend on the output of the humidifying fan 2500 when providing humidification. To make the moisture flow farther, if only depending on the output of the humidifying fan 2500, the capacity of the humidifying fan 2500 needs to be increased or the humidifying fan 2500 needs to be operated at a high speed. In this embodiment, when operating the humidifying assembly 2000, moisture can be stored in the air flow of the short-distance fan assembly and made to flow farther. In this case,

[0465] even by using a humidifying fan 2500 with a small output capacity, humidification can be provided to far places in the room. It is possible. That is, even if a humidifying fan 2500 with a small output capacity is used, humidification can be provided to far places in the room. It is possible.

[0466] Since the diffuser outlet 2431 is disposed behind the side outlets 301 and 302 humidified air can flow further forward by being disposed forward.

[0467] <<Configuration of Humidifying Fan>> The humidifying fan 2500 inhales filtered air that has passed through the filter assembly 600 and supplies it to the steam generator 2300, and causes the filtered air to flow to the steam guide 2400 together with the steam generated by the steam generator 2300.

[0468] The humidifying fan 2500 generates an air flow that discharges steam and filtered air (referred to as humidified air in this embodiment .) from the diffusers 2430 and 2440.

[0469] The humidifying fan 2500 inhales filtered air that has passed through the filter assembly 600, a humidifying fan housing 2530 that guides the inhaled filtered air to the steam generator 2300, a clean intake duct 2540 that is connected to the humidifying fan housing 2530 at the lower side and is disposed in front of the filter assembly 600 at the upper side and supplies the filtered air that has passed through the filter assembly 600 to the humidifying fan housing 2530, a humidifying impeller 2510 that is disposed inside the humidifying fan housing 2530 and causes the filtered air in the humidifying fan housing 2530 to flow to the steam generator 2300, and a humidifying motor 2520 that is disposed in the humidifying fan housing 2530 and rotates the humidifying impeller 2510.

[0472] In particular, the filtered air passing through the filter assembly 600 flows to the proximity fan assembly 300, and it is difficult or impossible for the filtered air to flow in the lower cabinet 120. Specifically, since there is no portion in the lower cabinet 120 where air is discharged, the filtered air does not flow or circulate inside the lower cabinet 120 unless artificially supplied.

[0473] Furthermore, since a drain fan 140 that supports the heat exchange assembly and collects condensed water is disposed below the upper cabinet 110, there are many constraints for the filtered air inside the upper cabinet 110 to flow into the lower

[0474] 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.

On the other hand, the second intake opening surface 2562 is formed in the second humidifying fan housing 2560 and is open downward. Including the above. The first humidifying fan housing 2550 includes a first intake opening surface 2552 formed thereon and opening upward. The clean intake duct 2540 is connected to the intake opening surface 2552. The second humidifying fan housing 2560 includes a second intake opening surface 2562 formed thereon and opening downward.

[0477] The first humidifying fan housing 2550 has a first intake opening surface 2552 formed thereon and opening upward. The clean intake duct 2540 is connected to the intake opening surface 2552. On the other hand, the second humidifying fan housing 2560 has a second intake opening surface 2562 formed thereon and opening downward. Including the above. Including the above.

[0478] The direction in which the first inhalation opening surface 2552 is opened in this embodiment is opposite to the direction in which the second inhalation opening surface 2562 is opened.
