In addition, the terms described below are defined in consideration of the functions of the present invention, which may vary depending on the intention or custom of the user, the operator. Therefore, definitions of these terms should be made based on the contents throughout this specification.

FIG. 1 is a perspective view of an air clean humidifier according to an embodiment of the present invention. FIG. 2 is a view showing the supply of air clean humidifier according to an embodiment of the present invention. Referring to FIG. 2, As follows.

Referring to FIGS. 1 and 2, an air clean humidifier 10 according to an embodiment of the present invention includes a humidifier 100 and a main body 200.

The humidifying unit 100 includes a water tank 110 in which water is stored and a humidifying filter 120 and a humidifying filter 120 which are provided inside the water tank 110 to absorb water, And a filter fixing frame 130.

The water tub 110 is formed in a cup shape, and is formed to be transparent or translucent so that the inside thereof can be seen through. This is a configuration that can check the water level with the naked eye. Of course, the water tray 110 may be formed to be opaque to form a water level window for confirming the water level.

The humidifying filter 120 absorbs the water stored in the water tub 110 and is in contact with the incoming air. The humidifying filter 120 may be made of various materials capable of absorbing water such as fibers and pulp.

The filter fixing frame 130 accommodates the humidifying filter 120 therein and serves to connect the water tub 110 and the main body 200.

The humidifying unit 100 includes an inflow line 140 into which outside air flows by the operation of the main body 200. The inflow line 140 is formed by a filter fixing frame 130.

2, the inflow line 140 is formed such that the inflow portion 142 formed between the water tub 110 and the filter fixing frame 130 and the outside air introduced into the inflow portion 142 are connected to the filter fixing frame 130 And a communication hole 144 formed in the filter fixing frame 130 to be introduced into the interior of the filter fixing frame 130.

A tubular filter fixing frame 130 is accommodated in the water tub 110 formed in a cup shape and a gap generated by a difference in diameter between the water tub 110 and the filter fixing frame 130 is formed in the inlet 142 .

The communication hole portion 144 is formed at an intermediate portion of the filter fixing frame 130 to enable smooth introduction of outside air. That is, the humidifying filter 120 absorbs the water of the water tub 110. If the water is absorbed by too much water, the humidification filter 120 hinders the air flow. Therefore, by forming the communication hole 144 at the middle portion, The humidifying filter 120 can be brought into contact with the upper end of the humidifying filter 120 to properly maintain humidification efficiency and air flow.

The inflow line 140 includes a filter unit 170 for filtering off foreign matter contained in the outside air.

The filter portion 170 includes a pre-filter covering the communication hole portion 144. At this time, the communication hole 144 has a polygonal cross-sectional shape, and the filter unit 170 has a plurality of unit filters corresponding to each surface so as to correspond to the communication hole 144.

The humidifying filter 120 is protected by a filter housing (not shown) and prevented from flowing in the filter fixing frame 130. Further, the humidifying filter 120 is formed in a cylindrical shape with a plurality of filter pieces arranged in the radial direction with respect to the center. A plurality of filter pieces are formed by folding one filter piece in a staggered manner.

The filter housing (not shown) is formed of a pair of wraps surrounding the periphery of the humidifying filter 120, and the corresponding portions are hooked and coupled to each other.

The main body 200 includes a housing 210 provided at an upper portion of the humidifying unit 100, a mounting bracket 220 provided at the housing 210, and an installation bracket 220, And a control unit 240 for controlling the operation of the power supply unit 223 and the power supply unit 223.

The housing 210 includes an inlet 212 through which air humidified by the blowing portion 223 flows and a discharge port 214 through which air introduced into the inlet 212 is discharged to the outside.

Since the main body 200 is provided on the upper portion of the humidifier 100, the external air introduced by the operation of the airflow portion 223 provided in the main body 200 flows into the side through the inflow line 140, And is discharged to the upper portion of the unit 200.

The discharge port 214 is provided with a shroud 225 for diffusing the discharged air to the outside. The discharge port 214 is formed at an interval between the mounting bracket 220 and the housing 210 and the shroud 225 is bound to the circumferential surface of the mounting bracket 220. The upper end of the shroud 225 is shaped like a ring extending outward, and diffuses the humidified air discharged through the discharge port 214 to the outside.

The power supply unit 223 is provided at a lower portion of the mounting bracket 220 and the power supply unit 223 is rotated by the operation of the drive motor 232 and the drive motor 232 driven by the operation of the control unit 240 And a safety grill 215 is formed in the housing 210 to prevent a safety accident due to the inflow of a finger when the fan member 234 rotates.

The control unit 240 includes a switch unit 245 provided in the mounting bracket 220 for applying an operation signal and a timer 244 for measuring the input time and the input time of the operation signal.

The switch unit 245 includes a detection sensor provided inside the mounting bracket 220. That is, when a user touches the upper surface of the mounting bracket 220, a signal is transmitted to the control unit 240 to drive the blowing unit 223. In this embodiment, the touching method of the switch unit 245 is an electrostatic method, but may be a depressurization method.

The installation bracket 220 is provided with a water supply line 260 for supplying water to the water tub 110.

2, the water supply line 260 includes a curved portion 262 formed at the center of the mounting bracket 220 so as to protrude in a convex shape and a water supply guide 260 provided at an edge of the curved portion 262, And a downward water supply guide 266 for transmitting the water in the water supply guide 264 and the water supply guide 264 to the water tub 110.

The water supply guide 264 is formed to be downwardly inclined toward the downward water supply guide 266 to guide the water flowing down from the curved portion 262 toward the downward water supply guide 266 side. At this time, the shroud 225 is provided to enclose the water supply guide 264 of the water supply line 260 to prevent the water from being separated.

An edge of the downward feed guide 266 is further provided with an attachment rib 267 which is in close contact with the inner surface of the housing 210. The contact ribs 267 isolate the downward water supply guide 266 from the outside and supply water to the water tank 110 through the downward water supply guide 266 to block water from flowing into the control unit 240 .

The blowing-out section 223 includes a driving motor 232 and a fan member 234.

The main body 200 is provided with a display unit 280 for displaying the operating state of the main body 200. 1, the display unit 280 is provided in the mounting bracket 220 and includes a power discharge window 285 for indicating an operation state and a function exposure window 286 for exposing different light emission motions according to functions . The function exposure window 286 is formed in a ring shape, and the light emission motion is changed according to the operation status of the main body 200.

That is, the speed of the fan member 234 is adjusted to adjust the amount of humidification. The speed of the light emission motion can be increased or decreased through the function exposure window 286 according to the driving speed of the fan member 234, .

Hereinafter, the humidifying operation of the air clean humidifier 10 according to the present embodiment will be described.

First, the user fills the water tank 110 with water. The air clean humidifier 10 according to the present embodiment supplies water to the upper part. That is, when water is supplied to the center of the mounting bracket 220, the supplied water is moved to the water supply guide 264 along the curved portion 262 and the water supply guide 264 is inclined to the downward water supply guide 266 And transfers the water to the water tub 110 through the downward water supply guide 266. At this time, the downward water supply guide 266 is provided with a contact rib 267 which is in close contact with the inner surface of the housing 210, so that water can be prevented from being introduced into another place.

Further, the shroud 225 is positioned so as to surround the periphery of the water supply guide 264 to prevent water from being released to the outside.

The supplied water is transferred to the water tank 110. Since the water tank 110 is made of a transparent or semi-transparent material, the user can adjust the water level with the naked eye.

Thereafter, when the external power is connected to the external power source through the power connection unit 290, the display unit 280 can confirm the power application state. This is because the power supply window 285 is illuminated to confirm the power supply state.

Here, the power connection unit 290 uses a vehicle power line (cigar jack) as shown in FIG. 1, but an AC adapter power line may also be used.

In the state where the power is applied, the user operates the switch unit 245 to operate the air clean humidifier 10. The switch unit 245 may include a sensing sensor provided inside the mounting bracket 220 and may apply an operation signal by a user's touch to the control unit 240. When the operation signal is applied to the control unit 240 as described above, the fan member 234 is rotated by the drive motor 232 to introduce the external air.

At this time, the light emission motion is exposed by the function exposure window 286 of the display unit 280, so that the driving state of the apparatus can be confirmed. The light emission motion through the function exposure window 286 is convenient for checking the amount of humidification by the rotation speed of the light emission motion.

When the fan member 234 rotates as described above, the outside air flows to the side through the inflow line 140 and is discharged to the outside through the discharge port 214 of the main body 200 to humidify the room.

In this humidifying operation, the external air is introduced through the inlet 142 by the rotation of the fan member 234. The external air introduced through the inflow portion 142 flows into the interior of the filter fixing frame 130 through the communication hole portion 144. The communication hole 144 is provided with a pre-filter to filter foreign matter such as dust.

The external air introduced into the filter fixing frame 130 comes into contact with the humidifying filter 120 to be humidified air and flows into the housing 210.

The humidified air introduced into the housing 210 is discharged to the outside through a discharge port 214 formed between the housing 210 and the mounting bracket 220 to humidify the room. At this time, the discharge port 214 is provided with a shroud 225 to discharge humidified air while diffusing it outward.

As described above, the air cleaner humidifier according to an embodiment of the present invention can humidify and purify indoor air by allowing external air to flow into and into contact with water.

In addition, the air cleaning humidifier according to the present embodiment includes a display unit interlocked with the operation of the blowing unit to provide convenience for the user to confirm the operation status.

FIG. 3 is a flowchart for explaining a power button malfunction prevention method of an air clean humidifier according to an embodiment of the present invention. Referring to FIG. 3, a method of controlling the air clean humidifier according to the present embodiment will be described.

As shown in FIG. 3, in the method of avoiding malfunction of the power button of the air cleaning humidifier 10, the initial power supply of the air cleaning humidifier 10 is first applied and the apparatus enters a standby state (S100, S200). An initial power source of the air cleaner humidifier 10 is applied when a power source connection unit 290 is connected. The power source connection unit 290 may include a vehicle power source line (cigar jack) and an AC adapter power source line.

Here, the standby state means a state in which the control unit 240 operates the switch unit 245 after the power supply connection unit 290 is connected, until the control unit 240 drives the power supply unit 230.

Next, the control unit 240 checks whether an input signal is generated from the switch unit 245 (S300). At this time, if an input signal is not generated, the input signal is initialized and the process returns to step S200 to maintain the standby state (S200).

For example, the power and mode of the air cleaner humidifier 10 may be set by the operation of the switch unit 245 in step S300. The mode set in the above may be displayed on the display color of the power exposure window 285 provided in the display unit 280 .

Meanwhile, in the present embodiment, the switch unit 245 generates an input signal according to the change of the electrostatic capacitance of the human body and the reference electrostatic capacity by the user touch by applying the electrostatic touch method.

Meanwhile, in the present embodiment, the air clean humidifier 10 includes a water supply line 260 at an upper portion thereof, and touches the switch unit 245 with water supplied during water supply. At this time, an input signal is generated according to the change of the capacitance of the water and the reference capacitance, and it is not possible to judge whether the touch operation is performed by the user's touch only by the capacitance.

Accordingly, the controller 240 should be able to compare the button input signal by the user's touch with the button input signal by the water.

If an input signal is generated from the switch unit 245 in step S300, the control unit 240 determines whether a second input signal is generated from the switch unit 245 within a predetermined time (S400). If the second input signal is not generated within the predetermined time or the second input signal exceeds the predetermined time, the control unit 240 initializes the input signal and returns to step S200 to maintain the standby state (S200) .

For example, in the present embodiment, when the input signal is generated twice consecutively within one second by setting one second in advance, the control unit 240 can determine that the touch operation is performed by the user's touch.

Accordingly, the control unit 240 drives the power supply unit 230 only when it is determined that the power button input signal is a user's touch based on the number of times of inputting the input signal and the input time (S500).

As described above, the control method of the air purifying humidifier according to the embodiment of the present invention provides an avoidance algorithm so that the power button is not mistakenly recognized as the input of the power button at the time of water supply, have.

In addition, the method for controlling an air cleaner humidifier according to an embodiment of the present invention can humidify and purify indoor air by allowing outside air to flow into the room.

In addition, the control method of the air purifying humidifier according to one embodiment includes a display unit linked to the operation of the blowing unit to provide convenience for the user to confirm the operating status.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it will be understood by those of ordinary skill in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
