Since the water discharged from the water tank 2100 flows into the supply chamber 2111 through two opening and closing processes, oversupply of water can be prevented. Specifically, since the supply plotter 2220 additionally controls the supply of water, the supply of water to the steam generator 2300 may be blocked.

Unlike the present embodiment, the water level sensor for detecting the water level may be disposed in the supply chamber 2211, and an opening / closing valve may be disposed in the chamber housing pipe 2214 to adjust the amount of water supplied to the steam generator 2300. This structure requires an additional level sensor and an on-off valve, which increases the manufacturing cost and requires an additional cable connection structure because it is controlled through an electrical signal.

In the present embodiment, since the supply amount of water provided to the steam generator 2300 is controlled through the supply plotter 2220 which is raised or lowered according to the level of the supply chamber 2211, the water level control in the steam generator 2300 is performed. The water supply can be mechanically implemented.

<< structure of steam generator >>

The steam generator 2300 receives steam from the water supply assembly 2200 to generate steam. Since the steam generator 2300 generates steam by heating water, the steam generator 2300 may provide sterilized steam.

The steam generator 2300 is disposed in the steam housing 2310, the steam housing 2310, the steam heater 2320 to generate heat by an applied power source, and the steam housing 2310. A water supply unit 2314 connected to the chamber housing pipe 2214 of the water supply assembly 2200 and receiving water, disposed in the steam housing 2310, connected to the steam guide 2400, and Steam discharging unit 2316 for supplying the steam generated in the steam guide 2400, and disposed in the steam housing 2310, is connected to the humidification fan 2500, from the humidifying fan 2500 It includes an air suction unit 2318 receives the filtered air in the cabinet assembly (100).

The steam housing 2310 has a structure sealed to the outside. Only the water supply unit 2314 and the steam discharge unit 2316 communicate with the steam housing 2310. The steam housing 2310 is installed in the base 130.

The steam housing 2310 includes an upper team housing 2311 and a lower steam housing 2312.

The upper team housing 2311 has an open shape at an upper side thereof, and is formed concave downward. The lower steam housing 2312 has an open shape at a lower side thereof, and is formed to be concave upward.

In the present embodiment, the water supply unit 2314 is disposed in the lower steam housing 2312, and the steam discharge unit 2316 is disposed in the upper steam housing 2311.

The water supply unit 2314 protrudes from the upper team housing 2311 toward the water supply assembly 2300. The water supply unit 2314 is connected to the chamber housing pipe 2214 and disposed in the transverse direction. In the present embodiment, the water supply unit 2314 has a hollow pipe shape.

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

In particular, the water supply unit 2314 is connected to the lowermost side of the lower steam housing (2312). In this embodiment, a separate valve is not disposed in the water supply unit 2314.

Since the water supply unit 2314 and the chamber housing pipe 2214 are in communication with each other, the level of the supply chamber 2211 and the 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 equally formed, and the supply of the water supply assembly 2200 is provided. The plotter 2220 rises as the water level rises, and the supply plotter 2220 may close the middle hole 2258 to which water is supplied.

In this embodiment, the chamber housing pipe 2214 is disposed within the height of the steam heater 2320. The chamber housing pipe 2214 is disposed below the maximum water level of the steam generator 2300.

The middle hole 2258 is disposed higher than the maximum water level of the steam generator 2300. In the present embodiment, the middle hole 2258 forms a separation distance H from an upper end of the steam heater 2320.

The steam discharge unit 2316 is in communication with the inner of the upper housing (2311). The steam discharge unit 2316 penetrates through the upper team housing 2311 in the vertical direction. The steam discharge unit 2316 protrudes upward from an upper surface of the upper team housing 2311 to be connected to the steam guide 2400.

The air suction unit 2318 is disposed in the steam housing 2310, and more specifically, is disposed in the upper team housing 2311. The air suction unit 2318 may communicate with the interior of the upper team housing 2311, and the air supplied from the humidifying fan 2500 may be introduced therein.

The air suction unit 2318 protrudes upward from an upper surface of the upper team housing 2311 to be connected to the humidifying fan 2500.

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

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

When general air, not filtered air, is introduced into the steam housing 2310, the inside of the steam housing 2310 is highly likely to grow mold and the like.

In the present embodiment, since the air supplied into the steam housing 2310 is limited to the filtered air, the inside of the steam generator 2300 may be minimized from being contaminated by bacteria or mold when the steam generator 2300 is not operated.

The steam generator 2300 according to the present embodiment may maximize the flow pressure of steam because the air flow of the humidification fan 2500 is supplied therein to push the steam out of the steam housing 2310.

Unlike the present embodiment, when the humidifying fan sucks steam outside the steam housing, steam inside the steam housing may not be smoothly discharged.

If the steam generated by the steam generator 2300 does not flow to the

side discharge ports

301 and 302 quickly, dew 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, dew condensation generated in the flow of steam can be minimized. In addition, in the present embodiment, since the air of the humidifying fan 2500 pushes the steam inside the steam housing 2310 out of the steam housing 2310, a sufficient air flow rate can be ensured.

In particular, in the present embodiment, even if dew condensation occurs during the flow of steam, the condensed water may spontaneously evaporate due to the air flow rate because the flow rate of the air flowing the steam is sufficiently secured.

In this case, the steam generator 2300 is provided with the respective steam discharge portion to which the first branch guide 2410 and the second branch guide 2420 are coupled.

In addition, unlike the present embodiment, only one branch guide may be disposed, and one branch guide may be provided to be coupled to one diffuser. In this case, one diffuser may be disposed only in either the first side outlet or the second side outlet.

In the present 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 the present 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.

The flow rate of the air discharged from the first diffuser 2430 and the flow rate of the air discharged through the first side discharge port 301 are similarly formed. Although the flow rate of the discharged air discharged from the first side discharge port 301 is larger than that of the humidified air, the flow rate is preferably similar. This is because if one flow rate is larger, it acts as a resistance to the other flow rate.

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

The second diffuser 2440 is assembled with the second branch guide 2420 and is disposed at 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.

301 and 302. When the humidifying air is discharged in front of the

side discharge ports

301 and 302, the humidifying air may be flowed farther.

The humidifying assembly 2000 according to the present embodiment does not depend only on the output of the humidifying fan 2500 when the humidification is provided. If only relying on the output of the humidification fan 2500 to flow moisture further, the capacity of the humidification fan 2500 must be increased or the humidification fan 2500 must be operated at high speed.

In the present embodiment, when the humidifying assembly 2000 is operated, moisture may be loaded into the air flow of the short-range fan assembly 300 so as to flow farther. In this case, even using a humidification fan 2500 having a small output capacity, it is possible to provide humidification to a far place in the room.

<< Configuration of humidification fan >>

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

The humidifying fan 2500 generates an air flow for discharging steam and filtered air (humidified air in this embodiment) from the

diffusers

2430 and 2440.

The humidifying fan 2500 sucks the filtration air passing through the filter assembly 600, the humidifying fan housing 2530 for guiding the sucked filtered air to the steam generator 2300, and the lower side of the humidifying fan housing.
