The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. Furthermore, the singular forms "a", "an," and "the" include plural referents unless the context clearly dictates otherwise.

Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings.

1 to 4, a humidifying device according to an embodiment of the present invention will be described.

1 to 4, a humidifier 100 according to an embodiment of the present invention includes a housing 110, a water tank 120, a water bottle 130, a rotary humidification filter 140, And a rotation driving unit 160. The control unit 150 may further include a controller for controlling the rotation driving unit 160, though not shown.

The housing 110 constitutes an external appearance of the humidifier 100 according to an embodiment of the present invention. The housing 110 includes an air inlet (not shown) through which external air flows into the interior of the humidifier 100, (Not shown).

In addition, a blowing fan (not shown) is installed in the housing 110 to generate air flow so that air flows into the air suction unit, passes through the rotary type humidifying filter 140, and is discharged to the outside through the air discharge unit .

In addition, an air filtering filter (not shown) may be additionally provided inside the housing 110 to clean air flowing into the housing 110.

The water tank 120 is provided inside the housing 110 and can store water for humidification. In an embodiment, the water tub 120 may be disposed at the lower inner end of the housing 110 and detachable outside the housing 110 as shown in FIGS. 1 and 2, but is not limited thereto.

The water bottle 130 may be detachably attached to the housing 110 and may be connected to the water tank 120 to supply water for humidification to the water tank 120 when the housing 110 is installed.

The rotary type humidification filter 140 may be partly immersed in the water tank 120 and rotatably mounted on the water tank 120 in the circumferential direction.

The rotary type humidification filter 140 may be disposed on the flow path of the air flowing inside the housing 110. The rotary type humidification filter 140 may be made of a breathable material that absorbs the water stored in the water tub 120. [ Here, the air flowing into the housing 110 passes through the rotary type humidifying filter 140 in a direction opposite to the one side, and vaporizes the water absorbed on the surface of the rotary type humidifying filter 140, So that indoor humidification can be performed.

Meanwhile, in one embodiment of the present invention, the rotary type humidification filter 140 may include a plurality of filter units having different moisture absorption amounts in a plurality of sections defined along the rotation direction.

In other words, the rotary type humidifying filter 140 has a plurality of filter portions, which are not made of one material and shape having the same total moisture absorption amount but are made of different materials or shapes having different moisture absorption amounts, Respectively.

Further, in one embodiment, the plurality of filter units may be configured to be detachable from each other. Thus, each of the plurality of filter units can be independently exchanged and cleaned. However, the present invention is not limited thereto, and the plurality of filter units may be integrally formed.

3 and 4, the plurality of filter units are combined to form a disc-shaped rotary type humidification filter 140. The first filter unit 141 and the second filter unit 141 constitute a disc- And a filter unit 142.

1 to 4, the second filter unit 142 includes a circular arc corresponding to a part of the circumferential direction of the rotary type humidification filter 140, and both ends of the circular arc are linearly cut The first filter unit 141 may be configured to exclude the second filter unit 142 from the rotary type humidification filter 140. However, the present invention is not limited thereto, and the second filter unit 142 may have a central angle It can also be composed of sectors with acute angles.

1 to 4, when the second filter unit 142 has a shape similar to a semicircular shape as described above, when the second filter unit 142 is immersed as shown in FIG. 1, Since the area exposed to the upper portion of the second filter unit 142 is larger than the area occupied by the second filter unit 142 in the rotating type humidifying filter 140, the amount of humidification by the second filter unit 142 is increased.

Of course, in the case where both ends of the second filter portion 142 are formed as a sector extending to the center of the rotary type humidifying filter 140, the area exposed to the upper portion of the water tub 120 is larger than the shape in which both ends are cut in a straight line The humidifying efficiency may be lowered in the structure in which the upper end of the second filter unit 142 is excessively extended because the moisture absorption amount decreases toward the upper part of the filter due to the characteristics of the humidifying filter.

Meanwhile, in one embodiment, the first filter unit 141 may be made of a material having a smaller moisture absorption amount than the second filter unit 142. For example, the first filter unit 141 may be a three-dimensional cloth filter, and the second filter unit 142 may be a Peats type filter. Here, the three-dimensional fabric filter is easy to clean, the price is low but the amount of moisture absorption is small, and the pleats type filter has a large amount of moisture absorption, but the price is relatively higher than that of the three-

The first filter unit 141 constituted by the three-dimensional fabric filter has a small amount of moisture absorption when it is immersed in a state of being stopped in the water tank 120. However, after storing water in a plurality of pores formed inside the water filter, The humidifying operation can be performed by supplying water to the entire area of the filter.

Also, in one embodiment, when the second filter unit 142 having a large moisture absorption amount is immersed in a state of being stopped in the water tub 120, the first filter unit 142 can absorb the water from the lower part to the upper part and perform the humidifying operation. 1, the second filter unit 142 is disposed in the water tub 120 (see FIG. 1) so that a part of the second filter unit 142 in which the water is absorbed is disposed in a flow path of air flowing into the housing 110, It is preferable that a part of the upper end protrudes to the upper end of the water tub 120. [

Here, the humidifier 100 according to an embodiment of the present invention sets the area and the shape of the second filter unit 142 and adjusts the height of the second filter unit 142 protruding to the upper end of the water tub 120, Can be adjusted.

The filter frame 150 may be rotatably mounted on the upper part of the water tub 120 with a rotatable humidification filter 140 installed inside.

3, the filter frame 150 includes a front frame 151 mounted on the front surface of the rotary type humidification filter 140, a rear frame 151 mounted on the rear surface of the rotary type humidification filter 140, And a gear 154 mounted on a rim of the front frame 151 or the rear frame 152 to receive power from a rotation driving unit 160 to be described later.

The filter frame 150 is provided with guide projections 156 projecting inward from the rim of the filter frame 150 to guide the mounting positions of the first filter unit 141 and the second filter unit 142 May be provided.

3 and 4, the guide protrusion 156 is provided at a position where the first filter unit 141 and the second filter unit 142 meet with each other, and the first filter unit 141, And the second filter unit 142 may be formed in a shape protruding from the inner surface of the rim of the rear frame 152 to determine positions of both ends of the second filter unit 142.

Here, the guide protrusions 156 may protrude to a low enough height to display only the boundary between the first filter unit 141 and the second filter unit 142.

In the case where the rotary type humidification filter 140 in which the first filter unit 141 and the second filter unit 142 are integrated is mounted on the filter frame 150 or a conventional humidification filter made of one material, The guide protrusion 156 may not interfere with the body of the humidifying filter mounted on the filter frame 150. [ The filter frame 150 includes not only the rotary type humidification filter 140 in which the first filter 141 and the second filter 142 are separated but also the first filter 141 and the second filter 142, And a conventional humidifying filter composed of one material can be also installed.

The rotation driving part 160 is fixed to the inside of the housing 110 and may transmit power to the gear 154 formed around the filter frame 150 to rotate the filter frame 150. The rotation driving unit 160 may be any mechanical device capable of controlling the rotation direction and the rotation speed of the filter frame 150 without any particular limitation.

The rotation driving unit 160 may be operated by the control unit.

Meanwhile, the humidifier 100 according to an embodiment of the present invention may be configured to automatically switch between the first filter unit 141 and the second filter unit 142 according to operation modes (non-humidified mode, silent humidified mode, and general humidified mode) Can be automatically adjusted. That is, in the humidifying apparatus 100 according to an embodiment of the present invention, the first filter unit 141 can be immersed in the water tank 120 in the non-wet humor, and the second filter unit 142 can be immersed in the water tank 120 (120), and the rotary type humidification filter (140) can be rotated in the general humidification mode.

For this, in one embodiment, the humidification apparatus 100 according to an embodiment of the present invention may include a subject sensing unit 170, a first sensing unit 180, and a second sensing unit 190.

The sensing unit 170 may be formed of a magnet fixed to the rim of the filter frame 150, for example, so as to match the rotational behavior of the rotary type humidification filter 140.

The first sensing unit 180 may sense the sensing unit 170 at a first rotation angle of the rotary type humidification filter 140 and may transmit a sensed signal to the control unit. 2, the first rotation angle is a rotation angle in which the first filter unit 141 is immersed in the water tank 120 and the second filter unit 142 is located in the upper part of the water tank 120, And the rotation angle of the filter 140.

The second sensing unit 190 may sense the sensing unit 170 at a second rotation angle of the rotary type humidification filter 140 and may transmit a sensing signal to the control unit. 1, the second rotation angle is a rotation angle in which the second filter unit 142 is immersed in the water tank 120 and the first filter unit 141 is located at the upper part of the water tank 120, And the rotation angle of the filter 140.

Meanwhile, in one embodiment, the first sensing unit 180 and the second sensing unit 190 may be composed of a reed switch that is turned on and off by the magnetic force of the sensing unit 170 formed of magnets, It is not.

In this configuration, the control unit rotates the rotary type humidification filter 140 at a first rotation angle by the sensing signal of the first sensing unit 180 during the non-wet mode operation, and then rotates the rotary type humidification filter 140 Can be stopped. As a result, the first filter unit 141 is immersed in the water tank 120 and the second filter unit 142 is positioned above the water tank 120 as shown in FIG.

At this time, since the amount of moisture absorbed by the first filter unit 141 to absorb water to the upper end in a stationary state is small, indoor humidification hardly occurs. Here, when the operation of the blowing fan (not shown) is stopped, the operation of the apparatus is stopped, and if the blowing fan is operated, the function of cleaning the room by the air cleaning filter (not shown) can be performed.

In addition, the control unit rotates the rotary type humidification filter 140 at a second rotation angle by the sensing signal of the second sensing unit 190 during the silent mode operation, and then stops the rotation of the rotary type humidification filter 140 . As a result, the second filter unit 142 is immersed in the water tank 120 and the first filter unit 141 is positioned above the water tank 120, as shown in FIG.

At this time, since the second filter unit 142 has a large amount of moisture absorption, indoor humidification can be performed. Here, since the operation of the rotary drive unit 160 is stopped and the rotation of the rotary type humidification filter 140 is stopped, the operation noise of the apparatus can be remarkably reduced.

That is, in the silent mode, the first filter unit 141 is hardly used for humidification and the second filter unit 142 can be used for humidification.

In addition, the controller may continuously rotate the rotary type humidification filter 140 during normal humidification mode operation. A large amount of water can be absorbed into both the first filter unit 141 and the second filter unit 142 and the first filter unit 141 and the second filter unit 142 can be continuously rotated while the rotary type humidification filter 140 is continuously rotated. 2 filter unit 142 may all be used for humidification. In this general humidification mode, a high humidification amount can be ensured because both the first filter unit 141 and the second filter unit 142 are used for humidification. However, since the rotation and rotation of the rotation and rotation driving unit 160 of the rotation type humidification filter 140 Noise due to operation is generated.

The humidifying apparatus 100 according to an embodiment of the present invention as described above can perform various humidifying modes by configuring one rotating type humidifying filter 140 with a different type humidifying filter having different moisture absorption amounts.

Particularly, the humidifying apparatus 100 according to an embodiment of the present invention has an advantage of using a rotary type humidifying filter 140, and a silent humidifying mode capable of performing humidification even when the rotation of the filter is stopped .

While the present invention has been particularly shown and described with reference to particular embodiments thereof, it is evident that many alternatives, modifications and variations will be apparent to those skilled in the art without departing from the spirit and scope of the invention as defined by the following claims I would like to make it clear.
