Description

[0001] The present invention relates to a filter apparatus of a humidifier,

The present invention relates to a humidifier, and more particularly, to a filter apparatus of a vaporization type humidifier in which a disk for a humidifier can be easily coupled and separated.

The indoor air can maintain proper humidity (for example, 60% to 70%) to prevent respiratory disturbance and disease, and to create a pleasant indoor atmosphere. In order to control the humidity, a humidifier for discharging clean water into the room is used.

Humidifiers are classified according to the humidification method. The humidifying method includes a centrifugal atomizing humidifier for granulating the inhaled water by a centrifugal force, an ultrasonic wave generator for transmitting an electric signal of a predetermined frequency generated in the electric circuit to a vibrator placed in the water to generate cavitation, There are various types such as a humidifier, an electric heating type humidifier which generates water by heating water with a heater or an electrode rod, and a vaporization type humidifier which evaporates water by passing air through a wet filter. In recent years, evaporative humidifiers, which provide a better humidification effect by compensating for the disadvantages of conventional ultrasonic humidifiers and heating humidifiers, have been widely used. The evaporative humidifier is relatively less expensive than other humidifiers, has less electricity consumption, and has a characteristic of increasing the humidity slowly while not causing a large temperature change. In addition, the evaporative humidifier may be configured to perform both air cleaning and humidification using a blowing fan.

The vaporization type humidifier is provided with a filter device of a predetermined shape for vaporization. Although not shown in the figure, the filter device has a structure in which a plurality of annular discs are stacked in a stacked state and rotated by a predetermined rotational force. Therefore, the water on the disk is vaporized by the forced wind force of the blowing fan, and the vaporized air is discharged through the air discharge port to humidify.

However, the conventional evaporative humidifier has some problems as follows. First, the humidification efficiency varies depending on the amount of water on the disk due to the structure of the filter device. This is because the area of water stored on the surface of the disk is extremely limited. Therefore, there was a limitation in improving the humidifying efficiency of the humidifier.

Further, the evaporative humidifier has a shape in which a plurality of disks are superimposed in a laminated structure. Therefore, it is very troublesome to separate or reassemble the disk from the fixed shaft of the filter device to which the disk is connected. This made it difficult for the user to clean the humidifier easily, which resulted in another problem that the humidifier could not be used cleanly and cleanly. In addition, the conventional evaporative humidifier is mostly humidified while the water stored in the water tank is held intact. When the humidification is carried out with the water in such a state, there is a hygienic problem because the water tank may get stuck or smell.

Korea public utility model 20-2011-0004137 (April 27, 2011, evaporative humidifier)

Accordingly, it is an object of the present invention to provide a filter device of a vaporization type humidifier which can improve the structure of a filter device so as to facilitate detachment and attachment of a disk, thereby making it possible to use the humidifier more cleanly and efficiently.

According to an aspect of the present invention for achieving the above object, there is provided a floor panel comprising: a bottom plate forming a bottom surface; A coupling frame located above the bottom plate, the coupling frame having a disc mounted on the outer side and a filter mounted on the inner side; A cylindrical shaft formed upward from the bottom plate and connected to the motor shaft for rotation; And a lid positioned at an upper end of the coupling frame.

The coupling frame may include an annular ring piece; A plurality of vertical pieces arranged in a direction perpendicular to the ring piece; The guide groove includes a first groove portion and a second groove formed to extend downward from the first groove portion, the guide groove being formed in a direction perpendicular to the intersection point of the ring piece and the vertical piece, &Lt; / RTI >

The disk may further include a plate-shaped body; At least one rib protruding laterally from a surface of the body; A through hole formed along the rib; And a first guide bar and a second guide bar formed on one side of the body so as to be fitted and fixed corresponding to the first groove and the second groove, respectively. Wherein the first guide bar is located in the first groove and the second guide bar is located in the second groove.

Further, a coupling groove is formed at the bottom of the edge of the cover, and a part of the upper end of the vertical piece is fitted and fixed to the coupling groove.

According to the evaporative humidifier of the present invention as described above, the disk and the filter device improved the structure of the coupling frame in which the disk is detachably attached, and the internal cleaning of the disk and the coupling frame becomes more convenient, so that the humidifier can be cleanly used There is an effect that can be. And since the damaged or replaced disk is also easy to replace, it is possible to prevent the problem of the humidifying effect from being degraded due to the failed disk.

In addition, since the disk continuously rotates the water during the humidification operation, the problem caused by the water retention may be solved.

Disclosure of Invention Technical Problem [8] The present invention relates to a filter device, in which a disk mounted on an outer circumferential surface of a filter device rotates water stored in a water tank (i.e., a lower casing) to uniformly absorb water into the filter, And the humidification is forced. BRIEF DESCRIPTION OF THE DRAWINGS The above and other objects, features and advantages of the present invention will become more apparent from the following detailed description when read in conjunction with the accompanying drawings.

1 is a perspective view showing a vaporization type humidifier according to an embodiment of the present invention. 1, an appearance of the evaporative humidifier 1 is formed by a casing 100. As shown in Fig. The casing 100 mainly comprises an upper casing 110 forming an upper outer appearance of the evaporative humidifier 1 and a lower casing 120 forming a lower outer appearance. The upper casing 110 and the lower casing 120 can be coupled and separated from each other. The upper casing 110 is provided with an air inlet 111 through which air is sucked to the outer circumferential surface and an air outlet 112 through which the vaporized air is discharged from the lower casing 120 to the outside. Here, the size and shape of the air inlet 111 and the air outlet 112 may be different. In other words, it is basically capable of sucking in air and capable of humidifying by discharging vaporized air.

The upper casing 110 is provided with a control panel 113 for controlling the operation of the evaporative humidifier 1. The control panel 113 includes a plurality of buttons as well as a display unit for displaying the operation states of the button operation and the humidifier. In the embodiment, the control panel 113 is configured by a touch screen method so that the input and display operations can be performed together.

The interior of the evaporative humidifier will be described in more detail with reference to FIGS. 2 and 3. FIG. Fig. 2 is an exploded perspective view, and Fig. 3 is a sectional view.

Referring to the drawings, the lower casing 120 serves as a water tank for storing water. The filter device 200 is mounted in the lower casing 120. In the embodiment, the filter device 200 is configured such that not only the filter 270 but also the disk 250 are mounted together, which will be described in detail below. When the filter device 200 is mounted on the lower casing 120, an air transfer path P is formed between the inner circumferential surface of the lower casing 120 and the filter device 200. The air movement path P is connected to an air inlet 111 provided in the upper casing 110. That is, the air movement path P becomes a path between the air intake port 111 and the filter device 200. The air sucked into the air inlet 111 through the air transfer passage P is transferred to the internal space of the filter device 200 through a second filter (that is, a water filter) described later. At this time, a first filter (i.e., an air filter) 114 for removing impurities contained in the sucked air is provided on the inner side corresponding to the air inlet 111.

A fan device 300 is mounted on the upper casing 110. The air blowing device 300 is located above the filter device 200 and receives the air that has been vaporized from the filter device 200 and discharges the air to the outside. The fan 300 includes a centrifugal fan 310 and a drive motor 320 for rotating the centrifugal fan 310. [ The centrifugal fan 310 forcibly sucks the vaporized air from the filter device 200 located in the lower casing 120 in the upward direction and sends it out through the air outlet 113. The driving motor 320 is connected to the control panel 113). The drive motor 320 operates by a reserved operation, a timer function, and the like as well as a basic function for operation / stop. The driving motor 320 is also connected to the cylindrical shaft 201 provided in the filter device 200. Accordingly, when the driving motor 320 is driven, the centrifugal fan 310 and the filter device 200 rotate together.

The structure of the filter device 200 will be described in detail with reference to FIGS. 4 to 6. FIG. The filter device 200 includes a coupling frame 230 that forms an outer skeleton and a bottom plate 220 and a cover 280 that engage with the bottom and top surfaces of the coupling frame 230.

The joining frame 230 includes a substantially ring-shaped ring piece 232 and a plurality of vertical pieces 234 disposed at right angles to the ring piece 232. The plurality of vertical pieces 234 are spaced apart from each other at regular intervals . The guide groove 240 is formed to be long in the vertical direction by the combination of the ring piece 232 and the vertical piece 234. The guide groove 240 is a portion where the guide bar 260 of the disc 250 is fastened and the guide bar 260 slides downward from the upper end of the guide groove 240 and is coupled thereto. The guide groove 240 includes a first groove portion 240a and a second groove portion 240b extending from a lower end of the first groove portion 240a to form an overall shape. The first groove portion 240a and the second groove portion 240a, (240b) is formed to correspond to the shape of the guide bar (260). The first groove portion 240a is formed by the vertical length of the ring piece 232 and the second groove portion 240b is formed longer than the first groove portion 240a so that the disc 250 is stably fixed to the guide groove 240 . This is to prevent the disc 250 from being strongly shaken or easily detached from the guide groove 240 by the resistance of the water when the disc 250 rotates. Also, a part of the upper end of the vertical piece 234 protrudes higher than the surface of the ring piece 232. A part of the projecting vertical piece 234 is fitted into the engaging groove 282 formed on the bottom surface of the lid 280 described below. A cylindrical shaft 201 is formed on the bottom plate 220 of the filter device 200 and is a portion where the motor shaft 322 of the driving motor 320 is engaged. Thus, when the driving motor 320 is driven, the filter device 200 is rotated together with the disk 250, so that the disk 250 is also rotated in one direction.

The disk 250 is fitted and fixed to the guide groove 240. The configuration of the disc 250 is shown in FIG. As shown in the drawing, the disk 250 is a substantially plate-shaped body. Of course, the shape of the disc 250 may be any shape capable of easily pushing the water in the opposite direction of rotation when the disc 250 is rotated. For example, a screw. A rib 252 is formed on one surface of the disc 250, that is, a surface directly facing the water in the rotating direction during rotation. The ribs 252 are formed in such a manner that a plurality of the ribs 252 protrude from the surface in the transverse direction of the disk 250 as shown in the figure, to increase the water content while increasing the cross-sectional area of the disk 250. A plurality of through holes 254 are formed in the disk 250. The through hole 254 is for minimizing the contact resistance with the water when the disk 250 is rotated.

Meanwhile, the disk 250 should be easy to assemble / detach. The disc 250 has a structure for coupling with and separation from the guide groove 240 and a guide bar 260 having a shape corresponding to the guide groove 240 is formed in one end of the disc 250 in a vertical direction . The guide bar 260 is composed of a first guide bar 260a and a second guide bar 260b for fitting into the guide groove 240. The first guide bar 260a protrudes from the upper end of the disc 250 and the second guide bar 260b is formed integrally with the side surface of the disc 250 at the lower end of the first guide bar 260a. When the disc 250 is completely inserted into the guide groove 240, the first guide bar 260a is located in the first groove 240a. Therefore, the disc 250 is in a shape . It is also preferable that the disc 250 is slightly inclined at a predetermined inclination angle when the disc 250 is fastened to the guide groove 240. This is to allow the disc 250 to effectively push up the water as the filter device 200 rotates. The disk 250 can be easily coupled and separated only by sliding the guide bar 260 into the guide groove 240 so as to clean the filter device 200 as a whole, It can be easily replaced even if it is broken.

A filter 270 is mounted on the inner peripheral surface of the coupling frame 230. When the filter 270 is mounted, the inside and the outside of the coupling frame 230 are blocked. Of course, this is not a perfect shut-off, but air is available. The filter 270 absorbs the water that rides on the surface of the disc 250 by the rotational force of the disc 250 when the disc 250 rotates the water. Accordingly, the filter 270 that absorbs water is vaporized while passing outside air. In an embodiment, a water filter (or a cloth filter) may be used so that the filter 270 can absorb water evenly. As the material of the water filter 270, a nonwoven fabric or the like is often used. The water filter 270 also functions to remove impurities that may be included in the primary filtered air through the air filter 114. However, the filter is not necessarily used. A material that can only absorb water and humidify the air may be used instead of the filter 270.

The lid 280 coupled to the upper surface of the coupling frame 210 has a shape of a wheel. In particular, when the lid 280 is to be engaged with the engagement frame 210, the vertical piece 234 positioned below should also be engaged with the lid 280. Therefore, the engaging groove 282 (see FIG. 3) is formed in the circumferential direction at the bottom of the edge portion of the lid 280. In this case, the motor shaft 322 is engaged with the lid 280 and the cylindrical shaft 201, and therefore, when the driving motor 320 is driven, the disk 250 rotates.

Next, the operation of the evaporative humidifier constructed as described above will be described in detail. A predetermined amount of water is stored in the lower casing 120. When the user operates the operation button provided on the control panel 113, the drive motor 320 operates. When the driving motor 320 is operated, the centrifugal fan 310 rotates. At the same time, since the motor shaft 322 is connected to the cylindrical shaft 201 through the cover 280, the filter device 200 starts rotating together as a whole. At this time, the centrifugal fan 310 and the filter device 200 rotate in the same direction, and the rotational speed thereof may be the same or may be set differently. If the rotational speed is set differently, it would be possible to provide gears having a series of different gear ratios on the motor shaft 322.

When the centrifugal fan 310 and the filter device 200 are rotated according to the operation of the driving motor 320, the air inlets 111 formed in the upper casing 110 due to the difference between the inner and outer pressure of the evaporative humidifier 1, The air is sucked from the outside through the opening. The impurities contained in the air will be primarily removed through the air filter 114 provided on the side of the air inlet 111 when the air is sucked. The sucked air is transferred through the air transfer passage P connecting between the air inlet 111 and the filter device 200 and passes through the water filter 270 mounted on the inner peripheral surface of the coupling frame 230 . At this time, the disk 250 continuously rotates water stored in the lower casing 120. And due to the structural nature of the disc 250, the stored water rises upwards along the ribs 252 so that water is evenly absorbed in the second filter, the water filter 270. Therefore, moisture absorbed in the water filter 270 is vaporized by the air conveyed through the air movement path P, and as a result, air containing moisture, which has passed through the water filter 270, Lt; / RTI > At this time, since water is absorbed in the water filter 270, impurities that are not caught by the air filter 114 are removed once more due to the viscosity of the water absorbed in the water filter 270. In addition, a UV (ultraviolet) LED lamp, which is sterilizing means, is installed in the filter device 200 to sterilize not only the stored water but also the air passed through the water filter 270, thereby doubling the sterilizing effect.

The air delivered into the filter device 200 is lifted to the upper casing 110 side through the lid 280 by driving the centrifugal fan 310. And is discharged to the outside through the air discharge port 112 provided on the upper surface of the upper casing 110. At this time, the air discharged through the air outlet 112 is in a state in which the impurities are removed by the air filter 114 and the water filter 270, and since the state is sterilized by the UV LED lamp, the air is humidified with clean air . In addition, since the water is uniformly absorbed into the water filter 270 by the rotation of the disk 250, the humidification efficiency becomes better.

The state of the air flow according to the series of processes of sucking outside air according to the operation of the vaporization type humidifier 1 according to the present invention and vaporizing it and discharging it through the air discharge port 112 and humidifying it is shown in FIG. Respectively. 3, air sucked in the direction A and finally vaporized in the direction B is discharged. In the filter device 200, the air vaporized by the rotational force also moves upward while rotating.

As described above, in the present embodiment, the disk stirs the water stored in the water tank (i.e., the lower casing) and vaporizes the water evenly absorbed by the filter to generate humidification.

Meanwhile, the present invention can easily separate and couple the disc 250, which will be described. The operator separates the upper casing 110 and the lower casing 120. The upper casing 110 and the lower casing 120 are coupled to each other by a coupling structure using a screw thread, or a structure using a coupling protrusion and a locking protrusion, so that the upper casing 110 and the lower casing 120 can be easily separated. Since the motor shaft 322 is separated from the cylindrical shaft 201, the upper casing 110 and the lower casing 120 are substantially separated from each other.

Next, the lid 280 located at the upper end of the filter device 200 is removed. Since the upper end of the vertical piece 234 is also separated from the engagement groove 282 of the lid 280, the upper portion of the vertical piece 234 is also exposed. In this state, the operator holds one disk to be separated and slides upward. The first guide bar 260a and the second guide bar 260b are sequentially removed from the first groove portion 240a and the second groove portion 240b. By this sliding movement, the disc 250 is separated from the coupling frame 230.

On the contrary, when the separated disc is to be coupled, the second guide bar 260b of the disc 250 may be pushed in from the first groove portion 240a toward the second groove portion 240b. As described above, according to the present invention, it is possible to easily separate and connect the disk 250 by pulling up and pushing down the disk 250, so that the damaged disk can be easily replaced or the disk can be easily cleaned.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments. It will be apparent that modifications, variations and equivalents of other embodiments are possible. Therefore, the true scope of the present invention should be determined by the technical idea of the appended claims.
