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

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

Since the water discharged from the water tank 2100 flows to 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, oversupply of water to the steam generator 2300 can be prevented.

Unlike the present embodiment, a water level sensor that senses the water level inside the supply chamber 2211 is disposed, and an opening/closing valve is disposed in the chamber housing pipe 2214 to control the amount of water supplied to the steam generator 2300. This structure increases the manufacturing cost because it additionally requires a water level sensor and an on-off valve, and requires an additional cable connection structure because it is controlled through electric signals.

In this embodiment, since the supply amount of water provided to the steam generator 2300 is controlled through the supply plotter 2220 that rises or falls according to the water level of the supply chamber 2211, the water level inside the steam generator 2300 is controlled and The water supply can be mechanically implemented.

<<Composition of the steam generator>>

5 and 18 to 20, the steam generator 2300 receives water from the water supply assembly 2200 to generate steam. Since the steam generator 2300 generates steam by heating water, sterilized steam may be provided.

The steam generator 2300 is disposed in the steam housing 2310, the steam housing 2310, a steam heater 2320 generating heat by an applied power source, and the steam housing 2310. , A water supply part 2314 connected to the chamber housing pipe 2214 of the water supply assembly 2200 to receive water, and disposed in the steam housing 2310, connected to the steam guide 2400, and internally A steam discharge unit 2316 for supplying the steam generated in the steam guide 2400, is disposed in the steam housing 2310, is connected to the humidification fan 2500, and is connected to the humidification fan 2500. It includes an air intake part 2318 for receiving filtered air inside the cabinet assembly 100.

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

The water supply part 2314 protrudes from the upper team housing 2311 toward the water supply assembly 2300. The water supply part 2314 is connected to the chamber housing pipe 2214 and is disposed in the transverse direction. In this embodiment, the water supply part 2314 has a shape of a pipe with an empty inside.

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

In particular, the water supply part 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 part 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 formed equally.

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 to be the same, and the supply of the water supply assembly 2200 The plotter 2220 rises as the water level rises, and the supply plotter 2220 may close the middle hole 2258 through which water is supplied.

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

The steam discharge part 2316 protrudes upward from the upper side of the upper team housing 2311 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 2311. The air intake part 2318 communicates with the inside of the upper team housing 2311, 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 2311 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.

<<Steam Guide Composition>>

2 to 7 and 18 to 21, 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 300.

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.
