First, as shown in FIG. 5, the humidification filter 140 may be configured in a form in which a body is bent in a zigzag manner in a height direction.

As such, when water is supplied from the top of the humidifying filter 140 bent in a zigzag direction in the height direction, water flows down in a zigzag manner along the inclination of the body, so the flow rate of the water supplied to the humidifying filter 140 is slow and The staying time in the body of the filter becomes longer.

Through this, since the amount of water absorbed by the humidifying filter 140 increases, the amount of humidification of the device can be increased.

In addition, in one embodiment, the humidifying filter 140 may have plate-shaped portions 142 made of a moisture absorbing material that support the shape of the body bent in a zigzag pattern on both sides.

As shown in FIG. 5 , the plate portion 142 may be formed in a plate shape extending in the height direction, and may be coupled to both ends of the zigzag bent body to maintain the zigzag bent shape of the body.

In the configuration of the water supply tray 154 and the insertion hole 152, water stored in the water supply tray 154 may overflow into the insertion hole 152 and be supplied to the humidifying filter 140 as the water level increases.

Also, in one embodiment, the height of the supply side wall 155 forming the outer circumference of the insertion hole 152 inside the water supply tray 154 may be the same along the circumference of the humidifying filter 140 .

Through this, when the water level stored in the water supply tray 154 is higher than the height of the supply side wall 155, water overflows from the entire supply side wall 155, and an almost constant amount of water spreads over the entire circumference of the humidifying filter 140. can be supplied.

That is, since the height of the supply side wall 155 is the same along the circumference of the humidifying filter 140, water can be supplied to the upper part of the humidifying filter 140 in a balanced manner.

In addition, in one embodiment, a guide bar protrudes upward from the inner bottom of the water supply tray 154 and guides the water falling from the water supply nozzle 170 to the water supply tray 154 into the water supply tray 154 ( 157) may be provided.

The guide bar 157 can reduce noise generated by water falling from the water supply nozzle 170 .

Meanwhile, the guide protrusion 158 may be provided to be spaced apart from the water supply nozzle 170 . On the other hand, when the guide protrusion 158 is in contact with the outlet of the water supply nozzle 170 or disposed inside the outlet, the guide protrusion 158 narrows the opening area of the outlet of the water supply nozzle 170 so that the water supply nozzle A water film is formed at the outlet of 170, which may cause a problem in that water supply is not smooth.

Therefore, the guide protrusion 158 is spaced apart from the lower side of the water supply nozzle 170, thereby preventing the formation of a water film at the outlet of the water supply nozzle 170, thereby facilitating the discharge of water from the water supply nozzle 170. can

In addition, in one embodiment, the guide protrusion 158 is provided with a plurality of small-thickness protrusions spaced apart from each other to decompose water droplets falling from the water supply nozzle 170, thereby minimizing noise caused by falling water droplets.

On the other hand, as shown in FIG. 9, in one embodiment, the water tank 180 is the amount of water (L1) when the humidifying water tank 190 supplies water to the water tank 180 at the maximum water level, the humidifying filter 140 ) It is preferable to be configured to store more water than the sum of the water absorption amount (L2) and the amount (L3) of the water accommodated in the flow path (not shown) connected between the water tank 180 and the water supply unit 150. .

That is, it is preferable that the water storage capacity of the water tank 180 is configured to be equal to or greater than L1+L2+L3.

Since the humidifier 100 according to an embodiment of the present invention has a structure in which water stored in the water tank 180 is raised up and supplied to the upper part of the humidifier filter 140, some of the water supplied to the humidifier filter 140 is humidified. It may flow down along the filter 140 and be introduced into the water tank 180 again.

For this reason, when the storage capacity of the water tank 180 is limited to the amount (L1) of the maximum water level supplied from the humidifying water tank 190, the water flowing down from the humidifying filter 140 and the humidifying filter 140 Water flowing in a flow path connected between the pump member 172 and the water tank 180 may flow into the water tank 180, causing the water tank 180 to overflow.

Therefore, in the water tank 180 according to an embodiment of the present invention, as described above, the maximum water absorption amount L2 of the humidifying filter 140 and the flow path (not shown) connected between the water tank 180 and the water supply unit 150 The storage capacity can be designed in consideration of the amount of water (L3) that can be accommodated.

To this end, in one embodiment, as shown in FIG. 9, the water tank 180 has an extension portion 188 extending upward from the height of the water supply port 192 of the humidifying water container 190 on the outer wall of the frame mounting portion 184. ) can be formed.

Here, the height of the extension part 188 is the sum of the amount of water absorbed by the humidifying filter 140 (L2) and the amount of water (L3) accommodated in a flow path (not shown) connected between the water tank 180 and the water supply unit 150. It is desirable to form more than the extent to which water can be accommodated.

Next, with reference to FIGS. 10 to 13, the ultrasonic vibration humidification structure of the humidifier 100 according to an embodiment of the present invention will be described in detail.

10 to 13, in the humidifier 100 according to an embodiment of the present invention, the vibrator 200 is provided in the vibrating humidifier 186 of the water tank 180 disposed below the housing. It may be configured to join the atomized particles generated by the vibrator 200 to the discharge air discharged by the blowing unit 120 and discharge them to the outside.

To this end, in one embodiment, an atomizing particle passage 210 may be connected between the vibrator 200 and the fan casing 124 .

In this configuration, the humidifier 100 according to an embodiment of the present invention transfers the atomized particles generated by the vibrator 200 to the negative pressure generated in the air discharge passage 125 inside the fan casing 124 , Atmospheric pressure below atmospheric pressure) may be introduced into the air discharge passage 125 .

That is, the humidifier 100 according to an embodiment of the present invention does not have a separate fan for discharging the atomized particles generated by the vibrator 200 to the outside of the housing, and the humidifier filter 140 and the air purifying filter It is configured to discharge the atomized particles to the outside of the housing through the blowing unit 120 that generates an air flow passing through the 130.

To this end, it is necessary to generate a negative pressure below atmospheric pressure in the air discharge passage 125 inside the fan casing 124, which can cause the atomized particles to rise up to the air discharge passage 125.

Accordingly, a negative pressure generator 220 may be provided inside the fan casing 124 to generate negative pressure in a portion of the air discharge passage 125 .

Hereinafter, the structure and operation of the negative pressure generator 220 will be described in detail.

First of all, in one embodiment, the fan casing 124 may be provided with an open connection portion 128 so that the non-fired particle passage 210 and the air discharge passage 125 are connected to each other. Here, the connecting portion 128 may constitute a passage through which the atomized particles flowing through the atomized particle passage 210 are introduced into the air discharge passage 125 .

At this time, the negative pressure generating unit 220 may include a negative pressure generating plate 222 protruding toward the inside of the air discharge passage 125 from the end of the connecting portion so that a vortex is formed in the connecting portion 128 .

The negative pressure generating plate 222 is a plate-like member protruding to resist air flowing into the air discharge passage 125, and obstructs the flow path of air flowing from the air discharge passage 125 toward the connection part 128, thereby blocking the connection part. (128) can form a vortex.

In this way, when a vortex is formed in the connection portion 128, the flow rate of air increases in the portion where the vortex is formed, and as the flow rate of air increases, the pressure decreases, so that negative pressure may occur in the portion where the vortex is formed, that is, the connection portion 128 there is.

When a negative pressure is generated in the connection part 128, an airflow flowing from the vibrator 200 side to the connection part 128 side is formed in the atomizing particle passage 210 due to the characteristics of the fluid trying to flow to the low pressure side.

Through this, the atomized particles generated by the vibrator 200 flow from the water tank 180 to the connection part 128 along the internal air flow of the atomized particle flow path 210, and the air discharge passage 125 inside the fan casing 124 It can join the discharge air flowing into and be discharged to the outside of the housing.

Meanwhile, in one embodiment, the negative pressure generating plate 222 may be formed inclined along the flow direction of the air flowing into the air discharge passage 125 .

In contrast, when the negative pressure generating plate 222 is perpendicular to or inclined in the opposite direction to the flow direction of the air flowing into the air discharge passage 125, a vortex is formed at the end of the negative pressure generating plate 222 so that the connecting portion 128 Since the flow velocity is not maximized at , the magnitude of the sound pressure is relatively small.

In addition, in one embodiment, the negative pressure generating unit 220 is provided at the discharge end 126 of the air discharge passage 125 to reinforce the negative pressure generated by the negative pressure generating plate 222 (224) may additionally be included.

In one embodiment, the negative pressure reinforcing plate 224 may be configured as a plate-shaped member protruding inward of the discharge end 126 to resist air discharged from the discharge end 126 of the air discharge passage 125 .

Here, the negative pressure reinforcing plate 224 is provided at the end of one inner wall provided with the negative pressure generating plate 222 and the connecting portion 128 in the fan casing 124 . That is, a structure in which the connecting portion 128 is disposed between the negative pressure generating plate 222 and the negative pressure reinforcing plate 224 may be formed.

Such a negative pressure reinforcing plate 224 generates a second vortex before being discharged through the discharge end 126 to the vortex formed on the downstream side of the negative pressure generating plate 222 by the negative pressure generating plate 222, thereby forming a negative pressure generating plate ( 222) and the negative pressure reinforcing plate 224, the air can flow at a high flow rate.

That is, the air whose flow rate is first increased beyond the negative pressure generating plate 222 is secondarily increased in flow rate while passing through the negative pressure reinforcing plate 224, and through this, the air that has passed through the negative pressure generating plate 222 is immediately moved at a high flow rate. Airflow exceeding the negative pressure reinforcing plate 224 is formed, so that the pressure in the section between the negative pressure generating plate 222 and the negative pressure reinforcing plate 224 may be very low.

Through this, the negative pressure between the negative pressure generating plate 222 and the negative pressure reinforcing plate 224 is further amplified, so that a large amount of atomized particles can flow into the fan casing 124 through the connecting portion 128.

Meanwhile, in one embodiment, the negative pressure reinforcing plate 224 may have a protruding length P1 that is 1 to 1/2 times the protruding length P2 of the negative pressure generating plate 222 .

If the protruding length P1 of the negative pressure reinforcing plate 224 is shorter than 1/2 the protruding length P2 of the negative pressure generating plate 222, a sufficient amount of negative pressure may not be generated at the connecting portion 128. there is.

Conversely, when the protruding length P1 of the negative pressure reinforcing plate 224 is longer than the protruding length P2 of the negative pressure generating plate 222, flow resistance is formed in the air by the negative pressure reinforcing plate 224 and flow disturbance occurs. can Flow disturbance by the negative pressure reinforcing plate 224 becomes an obstacle to generating negative pressure.

On the other hand, in one embodiment, the negative pressure reinforcing plate 224 may be provided on the upper cover 110c and integrally formed with the grill member 118 mounted on the discharge end 126 of the fan casing 124. It is not limited.

Meanwhile, the humidifier 100 according to an embodiment of the present invention may visually display an operation of discharging the atomized particles generated by the vibrator 200 so that the user can visually check.

To this end, the humidifier 100 according to an embodiment of the present invention may include the aforementioned visualization window 230.

In one embodiment, the visualization window 230 may include a first coupling portion 232 , a second coupling portion 234 , a buffer space portion 236 , and a buffer layer 238 .

Here, the first coupling portion 232 may be formed in an opening shape to be coupled to the connection portion 128 provided in the fan casing 124 .

In addition, the second coupling part 234 may be configured in an opening shape so as to be connected to the atomizing particle flow path 210 .

In addition, the buffer space portion 236 is provided between the first coupling portion 232 and the second coupling portion 234, and the atomized particles flow from the first coupling portion 232 to the second coupling portion 234. path can be configured.

Also, the buffer film 238 may temporarily retain the non-fired particles introduced into the buffer space 236 in the buffer space 236 .

In one embodiment, the buffer film 238 is a film-like member that protrudes inside the buffer space 236, and the atomized particles introduced into the buffer space 236 flow directly to the first coupling part 232. Air may be guided so that it flows in a detour to the upper side of the buffer space 236 without doing so.

Through such a buffer film 238, by allowing the atomized particles to temporarily stay in the buffer space 236, the user can easily check the generation amount and flow of the atomized particles with the naked eye.

At this time, the top or the whole of the visualization window 230 may be made of a transparent material.

Although the present invention has been shown and described with respect to specific embodiments, those skilled in the art will variously modify and change the present invention within the scope of not departing from the spirit and scope of the present invention described in the claims below. We want to make it clear that it can be done.
