1 is an exploded perspective view of an air cleaner humidifier according to an embodiment of the present invention, and FIG. 2 is a cross-sectional view of the air cleaner humidifier according to an embodiment of the present invention.

As shown, the air cleaning humidifier 100 includes a main body case 110, a disk assembly 120 and a disk motor 140 installed in the main body case to form an appearance.

The main body case 110 includes a rear plate 111 having a plurality of suction ports 112 for sucking indoor air and a front plate 115 provided with an input unit 116 for receiving a user's command.

An air purification filter 113 is disposed between the rear plate 111 and the disc assembly 120 to purify the indoor air sucked from the inlet 112.

The disk assembly 120 includes a circular disk 121, a part of which is locked in the water tank 140, and a disk gear 122 integrally formed on the disk to rotate the disk by the disk motor 140, and a rotation position of the disk. Position detection unit 123 for detecting the.

In the present embodiment, the position detecting unit 123 is composed of a magnet 123 and a magnet switch 123b, but the present invention is not limited thereto, and the position detecting unit 123 may be adopted as any switch capable of detecting the rotational position of the disk, such as an optical sensor. .

The disk 121 has a partition structure in which a plurality of wings are disposed at regular intervals between two sheets of discs having an empty disc shape, and a blowing fan 115 is located at the center thereof.

A portion of the disk 121 includes a cutout 121a cut out to allow the wind blown by the blowing fan 115 to pass therethrough, and a magnet at the center portion 121b of the disk opposite to the cutout 121a. 123a is fixedly installed.

The disk motor 140 may selectively drive the forward rotation or the reverse rotation in a state in which the rotary gear 141 coupled to the motor shaft is bitten by the disk gear 122.

In this embodiment, the disk motor 140 is implemented as a step motor (step motor) capable of bidirectional rotation, but is not limited thereto, and the disk may be rotated using any motor capable of forward rotation and reverse rotation. .

Referring to Figure 3, the control unit 101 controls the overall operation for the air cleaning humidifier 100 according to an embodiment of the present invention.

An input unit 116 and a position sensing unit 123 are connected to an input side of the control unit 101, and a disk driving the blower fan drive unit 102 and the disc motor 140 that drive the blower fan motor 115 to the output side thereof. The driving unit 103 is electrically connected.

When the control unit 101 simultaneously drives the blower fan 115 and the disc 121 in the air cleaning and humidifying mode, the air purified air passes through the rotating disc 121 and exits to the outlet 114.

In the air-cleaning and humidifying mode, when the cutout 121a of the disk is immersed in the water tank 130 and the portion of the disc 121 that is not cut out is exposed out of the water bath, the amount of humidification can be increased. That is, when the wind portion blown by the blower fan 115 passes through the disk in a state where the disk portion written in the water is located at the outlet 114, a large amount of moisture may be included in the air.

When the air cleaning and humidification mode is set, it is preferable that the disc cutout 121a is immersed in the water tank 130 and thus the disc center 121 is positioned closest to the outlet 114. This is called the initial disk position. The controller 101 may control the position of the disc 121 according to the signal of the position sensing unit 120 and set the initial position of the disc.

When the disc center portion 121b is located at the magnet switch 123b, the disc cutout 121a is positioned at the position closest to the outlet 114.

When the magnet 123a provided in the disk center portion 121b is located at a predetermined range from the magnet switch 123b, the magnet switch 123b is turned on and off when it is out of the predetermined range. In consideration of this, the control unit 101 counts according to the signal sensed by the magnet switch 123b and controls the rotation of the disc 121 using the count time so that the disc center 121b can be positioned at the magnet switch 123b. Can be.

Referring to FIG. 4, the trajectory 121c of the magnet 123a passes through the first point P1, the third point P3, and the second point P2 in sequence when the disk 121 rotates forward. Here, it is assumed that the interval between the first point P1 and the third point P3 and the interval between the second point P2 and the third point P3 are the same.

When the magnet 123a enters the first point P1, the magnet switch 123b is turned on, and when the magnet 123a leaves the second point P2, the magnet switch 123b is turned off. do.

The controller 101 performs a cumulative count until the magnet 123a enters the first point P1 and reaches the second point P2 to find out the count time A. FIG. Then, a reference time B corresponding to half A / 2 of the count time A is calculated. This reference time B corresponds to the time taken to return from the second point P2 to the third point P3.

The controller 101 reversely rotates the disc 121 at the second point P2, and the disc reverse rotation continues until the disc center portion 121b reaches the magnet switch 123b. When the cumulative counted time C during the reverse rotation reaches the reference time B, the third point P3 becomes a position corresponding to the magnet switch 123b, so that the controller 101 rotates the disc. To stop.

Then, when the disk 121 is rotated another half a turn, the disk cutout 121a is locked in the water tank 130, that is, the disk 121 is set to the initial position of the disk.

In this state, the controller 101 drives the blower fan 115 and simultaneously drives the disk 121 to perform air purification and humidification. Here, the control unit 101 controls the disk rotation direction and rotation speed in order to maximize the amount of humidification. This will be described in detail.

When the disc 121 is set to the disc initial position (FIG. 5A), when the disc is rotated forward, a portion of the disc is written in the water tank (FIG. 5B). At this time, the control unit 101 increases the disk rotation speed step by step. Then, the disk center portion 121b is immersed in the water contained in the water tank 130 so that the magnet switch 123b is turned on to reach the first point P1 (FIG. 5C).

When the disc center portion 121b reaches the first point P1, the controller 101 rotates the disc 121 in reverse (FIG. 5D). The controller 101 gradually decreases the disk rotation speed during the disc reverse rotation.

Thereafter, the disc cutout 121a is locked in the water tank 130 to reach the fourth point P4 at which the disc center 121b is closest to the outlet 114 (FIG. 5E). At this time, the control unit 101 increases the disk rotation speed step by step. Then, the disk center portion 121b is immersed in the water contained in the water tank 130, so that the magnet switch 123b is turned on to reach the second point P2 (FIG. 5F).

When the disk center portion 121b reaches the second point P2, the controller 101 rotates the disk 121 forward (FIG. 5G). At this time, the control unit 101 decreases the disk rotation speed step by step.

Thereafter, the disc cutout 121a is locked in the water tank 130 to reach the fourth point P4 where the disc center 121b is closest to the outlet 114 (FIG. 5H).

After the disk center portion 121b reaches the fourth point P4, the controller 101 gradually increases the disk rotation speed as shown in FIG. 5B and then repeats the above-described operation.

Hereinafter, an operation of setting a disc initial position according to an embodiment of the present invention will be described with reference to FIG. 6.

When the user sets the air cleaning and humidification mode through the input unit 116, the controller 101 performs a process of setting the disc central portion 121b to the initial position of the disc so that the disc center 121b is located closest to the outlet 114.

First, the disk 121 is rotated in the forward direction (200).

When the magnet 123a reaches the detection range of the magnet switch 123b, that is, the disk center portion 121b reaches the first point P1 (YES in 202), the controller 101 accumulates the forward rotation time. It counts (204).

Then, when the magnet 123a is off beyond the detection range of the magnet switch 123b, that is, when the disk center portion 121b reaches the second point P2 (YES in 206), the control unit 101 accumulates. The reference time (B = A / 2) is calculated according to the counted time (A) (208), and at the same time the disk (121) is rotated in the reverse direction (210).

Then, the controller 101 cumulatively counts 212 during the disc reverse rotation, and stops the disc rotation when the counted time C reaches the reference time (Yes of 214). Accordingly, the disk center portion 121b is positioned at the magnet switch 123b, and the disk cut portion 121a on the opposite side thereof is located closest to the outlet 114. In this state, the control unit 101 rotates the disc 121 another half turn (218). As a result, the disc 121 is set to the disc initial position.

Next, a method for controlling the rotational speed and the rotational direction in the air cleaning humidifier according to an embodiment of the present invention will be described with reference to FIG. 7.

As described above, the controller 101 drives the blower fan 115 while driving the disk 121 in the state where the disk is set to the initial position of the disk to perform air purification and humidification. At this time, the control unit 101 controls the disk rotation direction and the rotation speed in order to maximize the amount of humidification.

First, when the disk 121 is set to the initial position of the disk as shown in FIG. 5A, when the disk is rotated forward, a portion of the disk is written in the tank as shown in FIG. 5B (300). At this time, the control unit 101 increases the disk rotation speed step by step (302).

Then, if the disk continues to rotate forward, as shown in FIG. 5C, when the disk center portion 121b is immersed in the water contained in the water tank 130, the magnet switch 123b is turned on to reach the first point P1 (Example of 304) As shown in FIG. 5D, the control unit 101 rotates the disc 121 in reverse (306). At this time, the controller 101 decreases the disk rotation speed step by step (308).

Thereafter, if the disk reverse rotation continues, as shown in FIG. 5E, the disc cutout 121a is locked in the water tank 130 so that the initial position of the disc, that is, the disc center 121b is closest to the outlet 114, is the fourth point P4. When reaching (Yes of 310), the control unit 101 increases the disk rotation speed step by step (312).

Thereafter, as shown in FIG. 5F, when the disk center portion 121b is immersed in the water contained in the water tank 130 and the magnet switch 123b is turned on to reach the second point P2 (Example of 314), as shown in FIG. 5G. The controller 101 rotates the disk 121 forward (316). At this time, the control unit 101 decreases the disk rotation speed step by step (318).

Thereafter, when the disk forward rotation continues, as shown in FIG. 5H, the disk cutout 121a is locked in the water tank 130 so that the initial position of the disk, that is, the fourth point P4 at which the disk center 121b is closest to the outlet 114, is shown. Is reached (Yes of 320), it is determined whether the operation is stopped (322).

If the operation is not stopped, the controller 101 gradually increases the disk rotation speed as shown in FIG. 5B and then repeats the above-described operation.

As described above, the amount of humidification can be increased by controlling the disk rotation direction and the rotation speed so that the entire disk is evenly immersed in the water tank, while allowing the disk cutout 121a to move away from the outlet 114.
