Description

Humidifier {HUMIDIFIER}

The present invention relates to a humidifying device, and more specifically, to a humidifying device including a rotary humidifying filter that rotates while immersed in a water tank and absorbs water.

In a humidifier using a rotary humidification filter, the disc-shaped rotary humidification filter is rotatably placed at the top of the water tank so that it absorbs water stored in the water tank.

In addition, rotating humidifying filters are generally composed of three-dimensional fabric filters, so although the material itself does not have a large amount of moisture absorption, it is characterized by securing an abundant amount of humidification by adsorbing water on the surface and dispersing it throughout the filter as it rotates.

Meanwhile, a humidifier using such a rotary humidifying filter is provided with a drive motor for rotating the rotary humidifying filter. The drive motor transmits power to the filter frame on which the rotary humidification filter is mounted and rotates the filter frame and the rotary humidification filter.

However, in the case of a humidifier using a rotary humidification filter according to conventional technology, the rotary humidification filter needs to be rotated continuously to secure a sufficient amount of humidification, and the rotary humidification filter is fixed without rotating. When used as a rotary humidifying filter, the moisture absorption amount is low due to the nature of the rotary humidification filter, so it is difficult to obtain the desired humidification amount.

For this reason, when a humidifier using a rotary humidification filter according to the conventional technology is operated while sleeping, sleep is disturbed due to motor operation noise generated by the continuous rotation of the rotary humidification filter and friction noise between parts when the filter rotates. There is a problem with this.

The present invention was conceived to solve at least some of the problems of the prior art as described above. As one aspect, it is possible to use a rotating humidification filter and operate in a static humidification mode in which the rotation of the humidification filter is stopped, but with a sufficient amount of humidification. The purpose is to provide a humidifying device that can secure.

As an aspect for achieving at least part of the above object, the present invention includes a water tank in which water for humidification is stored; and a rotary humidifying filter, the lower part of which is immersed in the water tank and rotatably provided at the upper part of the water tank, wherein the rotary humidifying filter has a plurality of different moisture absorption amounts in a plurality of sections divided along the rotation direction. A humidifying device including a filter unit is provided.

In one embodiment, the plurality of filter units may be configured to be separable from each other.

Additionally, in one embodiment, the plurality of filter units may include a first filter unit and a second filter unit that are combined with each other to form the rotary humidification filter in the shape of a disk.

Additionally, in one embodiment, the first filter unit may be made of a material that absorbs less moisture than the second filter unit.

For example, the first filter part may be made of a three-dimensional fabric filter, and the second filter part may be made of a pleats-type filter.

Additionally, in one embodiment, when the second filter unit is immersed in the water tank, it is preferable that a portion of the second filter unit protrudes to the top of the water tank so that it is disposed in a flow path of air flowing inside the housing.

In addition, the humidifying device according to an embodiment of the present invention includes a control unit that controls a rotary driving unit that rotates the rotary humidifying filter, and the control unit is configured to move the second filter unit to the upper part of the water tank when operating in a non-humidifying mode. Rotate the rotary humidifying filter so that it is positioned in the position, rotate the rotary humidifying filter so that the second filter part is immersed in the water tank when operating in a quiet humidification mode, and continuously rotate the rotary humidifying filter when operating in a normal humidifying mode. You can.

In addition, a humidifying device according to an embodiment of the present invention includes a sensing unit whose rotational behavior matches that of the rotary humidifying filter; a first sensing unit that detects the detected unit at a rotation angle of the rotary humidifying filter in which the first filter unit is immersed in the water tank and the second filter unit is located at an upper portion of the water tank; And a second detection unit that detects the detected unit at a rotation angle of the rotary humidifying filter in which the second filter unit is immersed in the water tank. The rotation driving unit can be controlled according to the detection signals from the first detection unit and the second detection unit.

In addition, the humidifying device according to an embodiment of the present invention includes a filter frame on which the rotatable humidifying filter is mounted on the inside and rotatably mounted on the upper part of the water tank, and the filter frame includes the first filter unit and the second filter frame. 2 A guide protrusion may be provided protruding inward from the edge of the filter frame to guide the mounting position of the filter unit.

According to an embodiment of the present invention having this configuration, it is possible to obtain the effect of providing a silent humidification mode that can perform indoor humidification even when the rotation of the filter is stopped.

The terms used herein are only used to describe specific embodiments and are not intended to limit the invention. Additionally, in this specification, singular expressions include plural expressions, unless the context clearly dictates otherwise.

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

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

As shown in Figures 1 to 4, the humidifying device 100 according to an embodiment of the present invention includes a housing 110, a water tank 120, a water tank 130, a rotary humidifying filter 140, and a filter frame. It may include 150 and a rotation drive unit 160, and although not shown, it may further include a control unit that controls the rotation drive unit 160.

The housing 110 constitutes the exterior of the humidifying device 100 according to an embodiment of the present invention, and includes an air intake part (not shown) through which external air flows into the inside and an air discharge part through which internal air is discharged to the outside. (not shown) may be provided.

In addition, the inside of the housing 110 will be provided with a blowing fan (not shown) that generates air flow so that air flows into the air intake unit, passes through the rotary humidifying filter 140, and is then discharged to the outside through the air discharge unit. You can.

Additionally, an air purifying filter (not shown) may be additionally provided inside the housing 110 to purify the air flowing into the housing 110.

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

The water tank 130 is detachably provided in the housing 110, and when mounted on the housing 110, it can be connected to the water tank 120 to supply water for humidification to the water tank 120.

The rotary humidifying filter 140 may have its lower end partially immersed in the water tank 120 and be rotatable in the circumferential direction at the top of the water tank 120.

This rotary humidifying filter 140 is made of a breathable material that absorbs water stored in the water tank 120 and can be placed on the flow path of air flowing inside the housing 110. Here, the air flowing inside the housing 110 passes through the rotary humidification filter 140 from one side to the other side and vaporizes the water absorbed on the surface of the rotary humidification filter 140 to the outside of the housing 110. Indoor humidification can be performed by discharging.

Meanwhile, in one embodiment of the present invention, the rotary humidification filter 140 may be provided with a plurality of filter units with different moisture absorption amounts in a plurality of sections divided along the rotation direction.

In other words, the rotary humidifying filter 140 is not made of a single material or shape with the same moisture absorption amount over the entire area, but has a plurality of filter parts made of different materials or shapes with different moisture absorption amounts, each part of the total area of the filter. It can be configured to achieve.

Additionally, in one embodiment, the plurality of filter units may be configured to be separable from each other. Through this, each of the plurality of filter units can be independently replaced and cleaned. However, the present invention is not limited to this, and the plurality of filter units may be formed as one unit.

Meanwhile, in one embodiment of the present invention, a plurality of filter units are combined with each other as shown in FIGS. 3 and 4 to form a disk-shaped rotary humidification filter 140, including a first filter unit 141 and a second filter unit. It may consist of a filter unit 142.

As an example, the second filter unit 142 is composed of a circular arc corresponding to a partial section in the circumferential direction of the rotary humidification filter 140, and both ends of the circular arc cut with a straight line, as shown in FIGS. 1 to 4. The first filter unit 141 may be configured to exclude the second filter unit 142 from the rotary humidifying filter 140, but is not limited thereto, and the second filter unit 142 has a central angle. It may be composed of a fan shape with acute angles.

However, as shown in FIGS. 1 to 4, when the second filter unit 142 has a shape similar to a semicircle as described above, when the second filter unit 142 is immersed as shown in FIG. 1, it is placed in a water tank. Since the area exposed to the upper part of 120 is larger than the area occupied by the second filter unit 142 in the rotary humidifying filter 140, there is an advantage in that the amount of humidification by the second filter unit 142 is increased.

Of course, when both ends of the second filter unit 142 are configured in a fan shape extending to the center of the rotary humidifying filter 140, the area exposed to the upper part of the water tank 120 is larger than when both ends are cut straight. It may be wide, but due to the nature of the humidifying filter, the amount of moisture absorption decreases toward the top of the filter, so in a structure in which the upper end of the second filter unit 142 extends excessively high, the humidifying efficiency may actually decrease.

Meanwhile, in one embodiment, the first filter unit 141 may be made of a material that absorbs less moisture than the second filter unit 142. For example, the first filter unit 141 may be made of a three-dimensional fabric filter, and the second filter unit 142 may be made of a pleat-type filter. Here, three-dimensional fabric filters are easy to clean and inexpensive, but have low moisture absorption, while pleated-type filters have high moisture absorption but are relatively more expensive than three-dimensional fabric filters.

In addition, the first filter unit 141, which is made of a three-dimensional fabric filter, has a small amount of moisture absorption when immersed in a stationary state in the water tank 120, but when it rotates, it stores water in a plurality of pores formed inside and then rotates the filter. Accordingly, humidification can be performed by supplying water to the entire area of the filter.

Additionally, in one embodiment, the second filter unit 142, which absorbs a lot of moisture, may perform a humidifying operation by absorbing water from the bottom to the top when immersed in the water tank 120 in a stationary state. At this time, the second filter unit 142 is installed in the water tank 120 as shown in FIG. 1 so that the part of the second filter unit 142 in which the water is absorbed is disposed in the flow path of the air flowing inside the housing 110. ) When immersed in water, it is preferable that a portion of the upper part protrudes to the top of the water tank 120.

Here, the humidifying device 100 according to an embodiment of the present invention sets the area and shape of the second filter unit 142 to adjust the height protruding from the top of the water tank 120, thereby adjusting the humidification amount in the silent humidification mode to be described later. can be adjusted.

The filter frame 150 has a rotatable humidifying filter 140 mounted on the inside and can be rotatably mounted on the upper part of the water tank 120.

In one embodiment, the filter frame 150 includes a front frame 151 mounted on the front of the rotary humidifying filter 140, and a rear frame mounted on the rear of the rotary humidifying filter 140, as shown in FIG. It may be configured to include a gear 154 provided on the rim of the front frame 151 or the rear frame 152 and receiving power from the rotation drive unit 160, which will be described later.

Additionally, in one embodiment, the filter frame 150 has a guide protrusion 156 protruding inward from the edge 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.

In one embodiment, the guide protrusion 156 is provided at a location where the first filter unit 141 and the second filter unit 142 meet each other, as shown in FIGS. 3 and 4, and the first filter unit 141 And it may be formed in a protruding form on the inner surface of the edge of the rear frame 152 to determine the positions of both ends of the second filter unit 142.

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

Through this, when the rotary humidification filter 140 consisting of the first filter unit 141 and the second filter unit 142 is mounted on the filter frame 150, or when a conventional humidification filter made of one material is installed When mounted, the guide protrusion 156 may not interfere with the body of the humidifying filter mounted on the filter frame 150. This filter frame 150 is a rotary humidifying filter 140 in which the first filter unit 141 and the second filter unit 142 are separated, as well as the first filter unit 141 and the second filter unit 142. It has the advantage of being able to be equipped with a disc-shaped humidification filter that is integrated and a conventional humidification filter made of one material.

The rotation drive unit 160 is fixed to the inside of the housing 110 and can rotate the filter frame 150 by transmitting power to the gear 154 formed around the filter frame 150. This rotation drive unit 160 is not particularly limited, and may be composed of any mechanical device capable of controlling the rotation direction and rotation speed of the filter frame 150.

This rotation drive unit 160 can be operated by the control unit.

Meanwhile, the humidifier 100 according to an embodiment of the present invention automatically operates the first filter unit 141 and the second filter unit 142 according to the operation mode (non-humidification mode, quiet humidification mode, and general humidification mode). The position of can be adjusted automatically. That is, in the humidifying device 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-humidifying mode, and the second filter unit 142 can be immersed in the water tank 120 in the static humidification mode. It can be immersed in (120), and the rotary humidification filter (140) can be rotated in the general humidification mode.

To this end, in one embodiment, the humidifying device 100 according to an embodiment of the present invention may include a sensing unit 170, a first sensing unit 180, and a second sensing unit 190.

The sensing unit 170 is provided so that its rotation behavior matches that of the rotary humidifying filter 140, and for example, may be composed of a magnet fixed to the edge of the filter frame 150.

Additionally, the first detection unit 180 can detect the detected unit 170 at the first rotation angle of the rotary humidifying filter 140 and transmit a detection signal to the control unit. Here, the first rotation angle is a rotational humidification in which the first filter unit 141 is immersed in the water tank 120 and the second filter unit 142 is located at the top of the water tank 120, as shown in FIG. This is the rotation angle of the filter 140.

Additionally, the second detection unit 190 can detect the detected unit 170 at a second rotation angle of the rotary humidifying filter 140 and transmit a detection signal to the control unit. Here, the second rotation angle is a rotational humidification in which the second filter unit 142 is immersed in the water tank 120 and the first filter unit 141 is located at the top of the water tank 120, as shown in FIG. This is the rotation angle of the filter 140.

Meanwhile, in one embodiment, the first sensing unit 180 and the second sensing unit 190 may be configured as a reed switch that is turned on and off by the magnetic force of the sensing unit 170 composed of a magnet, but is limited to this. That is not the case.

In this configuration, the control unit rotates the rotary humidification filter 140 to the first rotation angle by a detection signal from the first detection unit 180 when operating in a non-humidifying mode, and then rotates the rotary humidification filter 140. can be stopped. Through this, as shown in FIG. 2, the first filter unit 141 is maintained immersed in the water tank 120, and the second filter unit 142 is located at the upper part of the water tank 120.

At this time, since the first filter unit 141 absorbs water to the top in a stationary state and has a small amount of moisture, almost no indoor humidification is achieved. Here, when the blower fan (not shown) stops operating, the device stops operating, and when the blower fan operates, the indoor air purifying function by the air purifying filter (not shown) can be performed.

In addition, when operating in the silent humidification mode, the control unit rotates the rotary humidification filter 140 to a second rotation angle by a detection signal from the second detection unit 190 and then stops the rotation of the rotary humidification filter 140. You can. Through this, as shown in FIG. 1, the second filter unit 142 is maintained immersed in the water tank 120 and the first filter unit 141 is located at the upper part of the water tank 120.

At this time, the second filter unit 142 can perform indoor humidification because the amount of moisture absorption is large. Here, since the operation of the rotary drive unit 160 is stopped and the rotation of the rotary humidifying filter 140 is stopped, the operating noise of the device can be significantly reduced.

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

Additionally, the control unit can continuously rotate the rotary humidification filter 140 when operating in the general humidification mode. Through this, a large amount of water can be absorbed in both the first filter unit 141 and the second filter unit 142, and the rotary humidification filter 140 rotates continuously to filter the first filter unit 141 and the second filter unit 142. Both filter units 142 can be used for humidification. In this general humidification mode, both the first filter unit 141 and the second filter unit 142 are used for humidification, so a high humidification amount can be secured, but the rotation of the rotary humidification filter 140 and the rotation drive unit 160 Noise is generated during operation.

As described above, the humidifying device 100 according to an embodiment of the present invention can perform various humidifying modes by configuring one rotary humidifying filter 140 with heterogeneous humidifying filters with different moisture absorption amounts.

In particular, the humidifying device 100 according to an embodiment of the present invention uses a rotating humidifying filter 140, but has the advantage of being equipped with a static humidifying mode that can perform humidification even when the rotation of the filter is stopped. .

Although the present invention has been shown and described with respect to specific embodiments, those skilled in the art can make various modifications and changes to the present invention without departing from the spirit and scope of the invention as set forth in the claims below. I would like to make it clear that it can be done.
