In the rotary type injection device of the prior art document, water is injected through air pressure and the direction of injection is determined through rotation of the injection nozzle, so that the structure is complicated and the noise is severe.

Further, even if the nozzle itself rotates 360 degrees, the above-mentioned rotary type spraying device can spray the liquid sucked into the inside of the device in the radial direction, but the height of the spot where the sprayed liquid strikes is limited. That is, it is difficult for the spraying apparatus disclosed in the preceding document to spray the liquid to the hit point expected by the user in the vertical direction. As a result, it is not appropriate to implement a spray capable of covering a wide range.

In addition, the rotary type injection device described above is also unsuitable for continuously supplying an appropriate amount of liquid to a position higher or lower than the position of the discharge part from which the liquid introduced from the injection device is discharged.

The water tank body extension part 380 may extend upward from the water tank 300. The plurality of water tank body extensions 380 may be provided, and the air wash inlet 31 may be formed. That is, the air wash inlet 31 may be formed between the plurality of water tank body extensions 380.

The air wash inlet 31 may be formed in a 360-degree forward direction with respect to the water bath body 320. The air wash inlet 31 may be formed to communicate with the humidification connection passage 105.

The air wash inlet 31 is located between the connection passage 103 and the humidification passage 106. The air wash inlet 31 is an outlet of the connection passage 103 and an inlet of the humidification passage 106. The filtered air supplied from the air clean module 100 flows into the air wash module 200 through the air wash inlet 31.

The water tank body extension part 380 can guide water flowing down from the inner side of the visual body 210 into the water tank 300. According to this, the water flowing down from the visual body 210 can be guided to minimize the dropping noise.

The water tank 300 may further include a water level sensor 355 for sensing the water level of the water to be stored.

The water level sensor 355 may be installed inside the water tank body 320 to sense the water level. For example, the water level sensor 355 can detect when the water level of the water stored below the minimum water level for spraying water by the water injector 400 drops. Accordingly, the user can replenish water when the water stored in the water tub 300 falls below the appropriate water level.

The visual body 210 may be coupled to the water tank 300 and may be located above the water tank 300.

The visual body 210 may be made of a material capable of viewing through the inside. Accordingly, the user can visually check the rainbow view implemented by the injector 400 through the outer visual body 241 and the visual body 210.

In addition, the visual body 210 may be formed of at least a part of the visual body 210 through which the inside of the visual body 210 is visible. However, the present invention is not limited thereto. For example, the visual body 210 may be formed of a translucent material.

For example, the discharge humidification medium 50 covers the discharge flow path 107, and humidified air flows through the discharge humidification medium 50 and then into the discharge flow path 107.

Also, the water tank humidifying medium may be located at the air wash inlet 31 of the water tank 300. It is preferable that the water tank humidifying medium is located inside the air wash inlet 31 because the water is wetted by the jetting device 400 for humidification. In addition, the water that has flowed in the water after humidifying the water humidifying medium may flow into the water tank 300 again.

Since the air wash inlet 31 is opened to communicate with the connection passage 103, water may be splashed into the connection passage 103 by the injection device 400 and leakage may occur. However, since the water tank humidifying medium is located at the air wash inlet 31, it is possible to prevent the water sprayed in all directions by the jetting device 400 from flowing into the connection flow path 103, have. In detail, the water jetted by the jetting device 400 strikes the water tank humidifying medium, so that kinetic energy is rapidly reduced, and sufficient force for flowing into the connecting flow path 103 is not obtained. Further, the water falling downward after the wetting of the water tank humidifying medium can be flowed back into the water tank 300, so that the water leakage described above can be prevented.

In order to prevent the above-described leakage, the air wash module 200 further includes a sealing portion (not shown) spaced apart from the air wash inlet 31 along the radial direction of the water humidifying medium .

The sealing portion (not shown) may form an inclined surface extending upward from the upper end of the water tub body 320 at a predetermined angle. The sealing part may be spaced outwardly from the water tank body extension part 380 and may have a larger distance from the upper end of the water tank body 320 toward the upper side. Therefore, even if the water impregnated with the water humidifying medium is splashed to the outside of the water humidifying medium, the water can be slid and returned to the inside of the water tank 300 by the sealing part.

Of course, the method for preventing water from being injected into the connection passage 103 by the injection device 400 is not limited to the above-described method. For example, a separate sealing portion may be formed in the connection passage 103.

The humidifying medium 50 provides humidification to the airflow inlet 31 and the filtered air passing through the discharge flow path 107. In detail, the filtered air can be humidified by the water that is naturally evaporated in the humidifying medium 50.

The natural evaporation refers to the evaporation of water in the absence of additional heat. As the contact with air increases, the flow rate of air increases, and the pressure in the air decreases, the natural evaporation can be promoted. Therefore, the humidifying medium 50 promotes natural evaporation of water.

Meanwhile, the top cover assembly 230 may be detachably mounted on the visual body 210. The top cover assembly 230 may not only provide the discharge passage 107, but may also provide a water supply passage 109 for supplying water.

The top cover assembly 230 may be positioned above the humidifying medium 50. The top cover assembly 230 may include a humidifying medium housing 1400 that can hold the humidifying medium 50 in a lower side. That is, the humidifying medium 50 may be installed in the humidifying medium housing 1400.

The top cover assembly 230 may be stacked and supported on the visual body 210. Accordingly, no load may be applied to the humidifying medium housing 1400.

The humidifying medium housing 1400 is installed inside the humidifying medium 50 and can cover the upper part of the visual body 210. The water supply passage 109 may be formed to pass through the humidifying medium housing 1400. Similarly, the discharge passage 107 may be formed to pass through the humidifying medium housing 1400.

The top cover assembly 230 may include an operation module 240 and a tower connector 270 for supplying power or signals to the operation module 240.

The operation module 240 can receive a user's operation signal. The operation module 240 is electrically connected to the top connector 270 and receives power from the top connector 270.

A part of the water supply channel 109 may be formed in the center of the operation module 240 in the vertical direction. The water supplied to the water supply channel 109 may be passed through the humidifying medium housing 1400 and may fall into the humidification channel 106. In addition, the falling water may fall to the top of the injector 400. In this case, even when the water is supplied, the falling water and the jetting device 400 collide with each other to form droplets into fine droplets. At the same time, the falling water is directed to the visual body 210, The view can be rounded. That is, falling water can also be re-injected by the injector 400 into the visual body 210.

In summary, when the injector 400 is rotating at the time of water supply, the water supplied is scattered on the injector 400, thereby forming a separate lane view. That is, not only the rain view can be formed through the water stored in the water tank 300, but also the rain view can be formed through the water that falls and is supplied.

The injector 400 may be disposed inside the water tank 300 and may rotate within the water tank 300. Therefore, water in the water tank 300 can be sprayed in all directions. That is, the injector 400 injects water into the air-wash module 200 to collide with the water, and the collided water is scattered to realize a lane view.

The lane view means the same effect as raining out of the window. More specifically, the lane view indicates a situation in which droplets formed on the inner surface of the visual body 210 appear as if a raindrop flows down.

Since the water is scattered and sprayed in all directions by the injector 400, it is possible to produce a lane view inside the visual body 210 by using it. The droplets generated by the above-described rain view can flow or float in the air flow path. The droplets can secondarily humidify, collect and purify the air to be flowed. In addition, the spraying device 400 can visualize a humidifying process of supplying water to the humidifying medium 50.

In summary, by the injector 400, effects such as raining or rain effect, that is, a rain view, are produced in the visual body 210. When the lane view is rendered, droplets of various sizes may be formed and scattered, and they may flow down on the inner circumferential surface of the visual body 210. Here, the inner circumferential surface portion of the visual body 210 through which droplets such as water droplets flow is called " window ".

The lane view allows the user to be visually stimulated, intuitively recognizing that humidification and air cleaning are being performed. In addition, since the image of falling water drops can be provided through the lane view, it is possible to obtain not only the emotional effect that gives the user a refreshing feeling but also the functional effect that can recognize the humidification and the air clean state.

Hereinafter, the configuration of the injector 400 will be described in detail.

FIG. 5 is a partial enlarged view showing an injection apparatus according to an embodiment of the present invention, FIG. 6 is a front view showing an injection apparatus according to an embodiment of the present invention, FIG. 7 is a view showing an injection apparatus according to an embodiment of the present invention FIG.

5 to 7, the injector 400 includes a power transmission unit (not shown) for providing power, a main rotation shaft 410 that receives power from the power transmission unit and rotates, 410 and a gear box 420 connected to the gear box 420.

The power transmitting portion may include a motor as an apparatus capable of providing power. For example, the motor may be positioned below the water tub 300 to provide a rotational force. That is, the power transmission unit may provide a rotational force to the main rotation shaft 410.

The motor connected to the main rotation shaft 410 may be called a main motor in order to distinguish it from a sub motor to be described later.

The main rotation shaft 410 may receive power from the power transmission unit and rotate. For example, the main rotation shaft 410 may be connected to the main motor and may be rotated by receiving the rotational force of the main motor.

The main motor is located below the water tank 300 and the main rotation shaft 410 connected to the main motor can be connected to the inside of the gear box 420 through the center of the bottom surface of the water tank 300 .

Of course, the injection module 400 may be rotated by receiving a rotational force by a method such as a belt-pulley, a gear engagement, a chain, a clutch, etc., in addition to a method of receiving a rotational force by rotation of the main rotational shaft 410.

The main rotation shaft 410 may be located inside the water tub 300. For example, the main rotation axis 410 may be located on the center axis of the water tub 300. In detail, when the water tank 300 has a cylindrical shape, the main rotation shaft 410 may extend in a vertical direction from a center of a circle forming a bottom surface of the water tank 300. Accordingly, the main rotation shaft 410 may be positioned so that at least a part of the water stored in the water tank 300 is submerged.

Meanwhile, the injector 400 may be rotated by the rotation of the main rotation shaft 410. More specifically, the gear box 420, the sub connecting shafts 431 and 441, and the aberrations 430 and 440, which are connected to the main rotating shaft 410 by rotation of the main rotating shaft 410, In the same direction. That is, the rotation of the main rotation shaft 410 can be understood as the rotation of the entire injection device 400.

The main rotation shaft 410 may be integrally coupled to the power transmission portion. Accordingly, the main rotation axis 410 may be called a power transmission axis.

Here, the rotation of the entire injector 400 by the rotation of the main rotation shaft 410 is called a first rotation. More specifically, the first rotation can be understood as rotating the main rotation axis 410 clockwise or counterclockwise with respect to the main rotation axis 410 corresponding to the center axis of the water tub 300.

The first rotation is a rotation of the main rotation shaft 410 in a clockwise or counterclockwise direction with the main rotation axis 410 as a center axis, The sub rotation shafts 431 and 441 and the aberrations 430 and 440 rotate in the same direction as the rotation direction of the main rotation shaft 410.

On the other hand, the rotation of only the first aberration 430, which will be described later, is called a second rotation, and the rotation of only the second aberration 440, which will be described later, is called a third rotation. For example, the first rotation may rotate in a direction perpendicular to the second rotation and the third rotation of the aberrations 430 and 440. A detailed description thereof will be described later.

The gear box 420 may be positioned above the main rotation shaft 410. The gear box 420 is coupled to the main rotation shaft 410 and rotates together with the rotation of the main rotation shaft 410.

The gear box 420 may connect the main rotation shaft 410 to the bottom surface of the water tank 300. The gear box 420 can be connected to the sub-rotating shafts 431 and 441 on both sides.

The gear box 420 may have various shapes. For example, the gear box 420 may have a cylindrical shape. The gear box 420 having the cylindrical shape may be rotated by 90 degrees. That is, two parallel and coherent circles of the cylinder can be located on both sides. At this time, the main rotation shaft 410 may be connected to the circumferential surface formed by connecting the two circles to the water tank 300, and the sub rotation shafts 431 and 414 may be connected to both sides of the gear box 420.

The gear box 420 may include a gear that transmits a rotational force by switching the rotational direction of the main rotational shaft 410. In detail, the gear can transmit the rotational force of the main rotation shaft 410 to aberrations 430 and 440 to be described later. The gears may change the rotation direction so that the rotation of the aberrations 430 and 440 rotates about an axis different from the axis of the first rotation.

Meanwhile, the gear box 420 serves to guide the rotation of the gear box 420 to separate from the main rotation axis 410, and thus may be referred to as a rotation switching unit.

The gears may include bevel gears that transmit motion between two axes that intersect each other.

The bevel gear includes a ring gear coupled to the main rotation shaft 410 and adapted to be subjected to the first rotation, and a bevel gear disposed on the center line of the ring gear and rotated about an axis intersecting the center axis of the ring gear And a pinion gear.

The pinion gear can be connected to the sub-rotating shafts 431 and 441. The plurality of pinion gears may be provided. Accordingly, the plurality of pinion gears can be connected to the plurality of sub rotation shafts 431 and 441. The aberrations 430 and 440 connected to the plurality of sub rotation shafts 431 and 441 may be rotated by receiving rotational force from the sub rotation shafts 431 and 441.

The crossing angle formed by the central axis of the ring gear and the central axis of the pinion gear may be perpendicular to each other, and may be formed to have an acute angle or an obtuse angle. Therefore, the power of the main rotation shaft 410 can be transmitted through the bevel gear in an acute angle or an obtuse angle. At this time, the bevel gear that transmits power in acute angle or obtuse angle is called angular bevel gear.

The sub rotary shafts 431 and 441 coupled to the pinion gear may be positioned so as to have an acute angle with the main rotary shaft 410 due to the energetic bevel gear. This is advantageous in that the area for splashing water can be increased because the water can be pumped up with a slope in the rotation operation of aberrations 430 and 440 to be described later. Accordingly, the sub-rotating shafts 431 and 441 may be more suitable for realizing the lane view than those connected to the gear box 420 so as to be inclined to be perpendicular to the main rotating shaft 410.

The bevel gear is advantageous in that it can generate a plurality of rotations in various directions by using one main motor of the power transmission unit. However, the plurality of revolutions can not be generated only by the main motor, but can also be generated by other methods.

As another method of generating the plurality of revolutions, an embodiment using a plurality of motors can be presented.

The gear box 420 may further include a sub motor. The plurality of sub motors may be provided. In detail, the sub motor may be provided corresponding to the number of the sub rotation shafts 431 and 441. For example, when two sub motors are provided, each of the sub motors may be rotated in opposite directions. Accordingly, the rotation directions of the sub-rotation shafts 431 and 441 can be rotated in opposite directions to each other. That is, if the sub-rotating shaft located on one side rotates clockwise, the sub-rotating shaft located on the other side can rotate counterclockwise.

The sub motor may be connected to the sub rotation shafts 431 and 441 to transmit rotational force. At this time, the sub-rotating shafts 431 and 441 may be connected to the sub-motor so as to form an acute angle with the main rotating shaft 410.

On the other hand, the case where the gear box 420 includes the bevel gear and the case where the sub motor is provided have advantages and disadvantages.

Specifically, the water stored in the water tank 300 forms a rotational flow by the rotation of the spray device 400, and can generate a swirling flow. The rotational speed and direction of the injector 400 are determined by the main motor. At the same time, the water stored in the water tank 300 is sprayed upward by the rotation of the aberrations 430 and 440 and splashed into the relatively large area toward the visual body 210.

The rotation of the aberrations 430 and 440 must provide a relatively high pressure to the water since the horizontal swirl flow must be pumped up in a vertical direction. At this time, the faster the horizontal vortex flow is, the less water is pumped by the aberrations 430 and 440, which may have an undesirable effect on the rain view implementation.

When the gear box 420 is connected to the sub rotation shaft using the bevel gear described above, the rotation speed of the aberration may be determined to be equal to or less than the rotation speed of the main motor depending on the rotation speed of the main motor have.

On the other hand, when the sub motor is connected to the sub rotation shaft by the gear box 420, the rotation speed of the aberrations 430 and 440 can be set independently of the rotation speed of the main motor, You can do it faster than speed.

In summary, it is preferable that the rotational speed of the aberrations 430 and 440 is formed to be faster than the rotational speed (first rotational speed) of the injector 400 for the real view implementation. Therefore, it is more advantageous to provide the sub-motor in the gear box 420 than the bevel gear in order to realize the preferable lane view. On the other hand, providing the bevel gear in the gear box 420 is economical because it is easy to manufacture because of its simple structure, less power consumption and lower manufacturing cost than the sub motor provided.

The injector 400 may further include sub-rotating shafts 431 and 441 connected to the gear box 420 and aberrations 430 and 440 connected to the sub rotating shafts 431 and 441.

The sub rotation shafts 431 and 441 may be rotatably connected to the gear box 420. The sub rotation shafts 431 and 441 may extend from the side surface of the gear box 420 toward the radial direction. That is, the sub rotation shafts 431 and 441 may be positioned on the side of the gear box 420.

The sub rotation shafts 431 and 441 connect the aberrations 430 and 440 to the gear box 420 and transmit rotational force to the aberrations 430 and 440.

The sub rotation shafts 431 and 441 may be disposed such that lines extending along the axis of the main rotation shaft 410 cross each other. Accordingly, the sub-rotating shafts 431 and 441 and the main rotating shaft 410 are different from each other in the direction of the rotating shaft. In detail, the sub-rotating shafts 431 and 441 may be rotated in the clockwise or counterclockwise direction in the vertical direction with the central axis positioned in the horizontal direction. On the other hand, the main rotation axis 410 may be rotated clockwise or counterclockwise in the horizontal direction with the center axis positioned in the vertical direction.

Here, the vertical direction refers to the vertical direction with respect to the center of the water tank body 320, and the horizontal direction refers to the direction toward the water tank body 320 with respect to the center of the water tank body 320. For example, when the water tank 300 has a columnar shape, the horizontal direction means the radial direction at the center of the water tank 300.

In short, the rotation of the sub rotation shafts 431 and 441 can be understood as a rotation in a direction different from the rotation (first rotation) of the main rotation shaft 410. For example, the sub rotation shafts 431 and 441 and the main rotation shaft 410 may be arranged to be perpendicular to each other, so that the first rotation is perpendicular to the rotation of the sub rotation shafts 431 and 441. Since the sub rotation shafts 431 and 441 are connected to the aberrations 430 and 440, the central axis of the first rotation may intersect perpendicularly to the central axis of the second rotation and the third rotation.

Further, as described above, the sub rotation shafts 431 and 441 may be connected to the main rotation shaft 410 by bevel gears. In this case, the rotation of the sub-rotation shafts 431 and 441 may be dependent on the rotation of the main rotation shaft 410 and may rotate. Accordingly, when the rotation of the main rotation shaft 410 is stopped, the rotation of the sub rotation shafts 431 and 441 is stopped, and the speed of the sub rotation shafts 431 and 441 may be at least equal to or slower than the rotation speed of the main rotation shaft 410 .

Alternatively, the sub-rotating shafts 431 and 441 may be connected through the auxiliary motor. In this case, the rotation of the sub-rotation shafts 431 and 441 can be independently rotated with respect to the rotation of the main rotation shaft 410. Therefore, even if the main rotation shaft 410 is stopped, the sub rotation shafts 431 and 441 can rotate, and only the aberrations 430 and 440 can independently rotate, and the rotation speed of the main rotation shaft 410 is controlled by the aberrations 430 and 440 ). ≪ / RTI >

The sub rotation shafts 431 and 441 may be connected to one side of the gear box 420 and the other side of the sub rotation shafts 431 and 441 may be inserted into the center portions of the aberrations 430 and 440,

The sub rotation shafts 431 and 441 may include a first sub rotation shaft 431 and a second sub rotation shaft 441.

The first sub-rotation shaft 431 may engage with the first aberration 430 described later. The second sub-rotation axis 441 may engage with the second aberration 440 described later. The first sub-rotation shaft 431 may be positioned symmetrically with the second sub-rotation shaft 441.

That is, the aberrations 430 and 440 may be coupled to the sub-rotating shafts 431 and 441 to rotate according to the rotation of the sub-rotating shafts 431 and 441.

Since the aberrations 430 and 440 raise water stored in the water tub 300 through rotation, at least a predetermined area of the water can be located in the water. Therefore, the lowermost end of the aberration 430 or 440 may be spaced upward from the bottom surface of the water tub 300. It is preferable that the lowermost ends of the aberrations 430 and 440 have a minimum separation distance considering the flow interference of water from the bottom of the water tub 300 so that the aberrations 430 and 440 efficiently raise water.

The aberrations 430 and 440 may form various shapes. For example, the aberrations 430 and 440 may have a cylindrical shape. More specifically, the aberrations 430 and 440 may have a wheel shape or a wheelbarrow shape.

The water of the water tank 300 is effectively pumped up by the rotation of the aberrations 430 and 440 and the centrifugal force due to the rapid rotation of the aberrations 430 and 440 causes the visual body 210 And the humidifying medium 50 and the like.

The rotation of the injection device 400 and the rotation of the aberrations 430 and 440 cause water droplets to be scattered to a position higher than the water level of the water stored in the water tank 300. The water droplets of each of the droplets The enemy can collide with each other irregularly with kinetic energy. Accordingly, the liquid droplet can be finely separated and sprayed into the visual body 210 and the humidifying medium 50 in a droplet form.

As described above, the aberration-shaped aberration 430, 440 has a more advantageous shape to implement the lane view. Therefore, in the embodiment of the present invention, the aberrations 430 and 440 having the spinner shape will be used as a reference.

The aberrations 430 and 440 may form a recessed space 439 along the periphery. Here, the outer peripheral surfaces of the aberrations 430 and 440 can be understood as the peripheral surfaces of the aberrations 430 and 440. That is, it is possible to form a recessed space 439 which is recessed inward at regular intervals along the circumference of the outer periphery of the aberrations 430 and 440. The aberrations 430 and 440 may receive the water in the water tank 300 through the depressed space 439 and spray the water to the humidifying medium 50 or the visual body 210.

The aberrations 430 and 440 may include both circular side surfaces through which the sub rotation shafts 431 and 441 are inserted and circumferential surfaces located between the both side surfaces and connecting both side surfaces. The circumferential surface rubs against the water of the water tub 300 directly through rotation to the outer circumferential surface of the aberrations 430 and 440.

The aberration 430.440 may further include depressed surfaces 436 and 446 recessed at predetermined intervals from the circumferential surface, and inclined surfaces 438 and 448 connecting the circumferential surface and depressed surfaces 436 and 444 with predetermined inclination.

The circumferential surface is formed at a greater distance from the centers of the aberrations 430 and 440 than the concave surfaces 436 and 446 in the radial direction and can be formed at a position higher than the concave surface by making a step with the concave surfaces 436 and 446. Thus, the circumferential surface is referred to as rising surface 437,447.

The recessed surfaces 436 and 446 are formed by recessing the circumferential circumference of the aberration 430 and 440 at a predetermined distance in the center direction by a predetermined distance. The recessed surfaces 436 and 446 are formed on one surface of the recessed space 439, Can be formed.

That is, the recessed space 439 may be formed by the recessed surfaces 436 and 446 and inclined surfaces 438 and 448 extending in the radial direction of the aberration from the edges of the recessed surfaces 436 and 446.

The inclined surfaces 438 and 448 can be inserted into the water of the water tank 300 to pressurize water when the aberrations 430 and 440 rotate clockwise or counterclockwise. Accordingly, the inclined surfaces 438 and 448 can be understood as pressure surfaces for applying pressure to water.

The water pressurized by the inclined surfaces 438 and 448 due to the rotation of the aberrations 430 and 440 can be received in the recessed space 439 and separated from the stored water of the water tank 300 and can be removed. The water in the recessed space 439 that has escaped into the upper space of the water surface of the water tank 300 is scattered in the direction of the humidifying medium 50 or the visual body 210 by the centrifugal force resulting from the rotation of the aberrations 430 and 440 It can be blown away.

A plurality of the aberrations 430 and 440 may be provided. In the embodiment of the present invention, the jetting apparatus 400 having two aberrations is described as a reference, but the number of aberrations is not limited thereto.

The aberrations 430 and 440 may include a first aberration 430 and a second aberration 440 disposed at a position facing the first aberration 430.

The first aberration 430 and the second aberration 440 may be positioned symmetrically with respect to an axis extending line of the main rotation axis 410. The first aberration 430 may be rotated 180 degrees along the circumferential direction of the water tank 300 from the second aberration 440. Here, the circumferential direction of the water tub 300 can be understood as a direction in which a virtual circle is drawn along the circumference of the water tub 300 having a cylindrical shape.

The first aberration 430 and the second aberration 440 can make the first rotation along with the main rotation axis 410 along the circumferential direction of the water tub 300.

Through the first rotation, the first aber 430 and the second aber 440 rotate together to provide rotational force to the water in the water tank 300. The water, which receives the rotational force through the first rotation, can rotate and generate a vortex flow. That is, the injector 400 may rotate the main rotation shaft 410 to generate rotation in the water in the water tank 300.

The first sub-rotation shaft 431 may be inserted into the center of the first aberration 430 to be inserted therethrough. The second sub-rotation shaft 441 may be inserted into the center of the second aberration 440 and inserted therein.

The first aberration 430 may include the recessed surface 436, the rising surface 437, and the inclined surface 438 described above. Similarly, the second aberration 440 may include a recessed surface 446, a raised surface 447, and a slanted surface 448.

Meanwhile, as described above, the central axis of the second rotation and the third rotation may be positioned in a direction perpendicular to the central axis of the water tub 300. [ In other words, the second rotation and the third rotation can be understood as a rotation which is obtained in a direction perpendicular to the water surface of the water stored in the water tub 300 and is extracted.

The first aberration 430 may rotate in a direction opposite to the rotation direction of the second aberration 440. For example, when the first aberration 430 rotates clockwise, the second aber 440 may rotate in a counterclockwise direction.

In another aspect, when the second rotation rotates clockwise with respect to the first sub-rotation axis 431, the third rotation may rotate counterclockwise with respect to the second sub-rotation axis 441. That is, the rotation direction of the second rotation and the rotation of the third rotation may be opposite to each other.

The water in the water tank 300 may be rotated by the first rotation. That is, water in the water tank 300 may generate a swirling flow. At this time, when the first aber 430 and the second aber 440 are rotated in the same direction, any one of the first aberration 430 and the second aberration 440 is in the swirl flow direction And the water is pressurized and raised.

For example, it is assumed that the first rotation is in the counterclockwise direction, and the second rotation and the third rotation are both clockwise with respect to the direction of the outer side of the first aberration 430 .

In this case, the water in the water tank 300 rotates in a counterclockwise direction, so that any one of the recessed spaces 439 of the second aberration 440 is in an intake direction in which water enters into the water and a rising direction Is substantially the same as the direction of the rotational flow of the water, and the flow resistance of the water is relatively small. On the other hand, the entering direction in which one recessed space 439 of the first aberration 440 is received into the water and the ascending direction protruding out of the water surface are in a direction against the rotational flow direction of the water, The resistance is relatively large. Accordingly, the first aberration 440 has a disadvantage in that the amount of water to be sprayed to the humidifying medium 50 and the visual body 210 is reduced when the water is pumped out of the water surface. Also, there is a disadvantage in that the rotational power of the first aberration 440 relatively increases in proportion to the increase of the flow resistance, which may cause a problem of power consumption increase. That is, it is inefficient.

The rotational direction of the first aber 430 corresponds to the rotational direction of the main rotational shaft 410 and the rotational direction of the second aber 440 corresponds to the rotational direction of the first aber 430 In the direction opposite to the direction of rotation of the rotor.

Specifically, when the first rotation rotates counterclockwise, the first aber 430 rotates counterclockwise on the basis of a direction viewed from the outside of the first aberration 430, 2 aberration 440 can be rotated clockwise. That is, when the first rotation is counterclockwise, the second rotation is counterclockwise and the third rotation is clockwise.

When the first rotation rotates clockwise, the first aber 430 rotates in a clockwise direction with respect to a direction seen from the outside of the first aberration 430, and the second aberration 440) can be rotated counterclockwise. That is, when the first rotation is clockwise, the second rotation is clockwise and the third rotation is counterclockwise. According to this, the first aberration 430 and the second aberration 440 are piled up in the rotational flow direction of the water and can float the water.

If the direction of the rotation of the first aber 430 and the second aber 440 is the same as the rotation direction of the second aber 440, Is reversed.

In order to realize a preferable lane view, the first aber 430 and the second aber 440 may be rotated in opposite directions so as to correspond to the rotational direction of the main rotating shaft 410 . According to this, since the aberrations 430 and 440 rotate in the direction in which the flow resistance is reduced, it is effective to scatter water in the water tank 300, and the power consumption can be relatively reduced, which is economical.

In addition, the first aber 430 and the second aber 440, which rotate in opposite directions to each other, can cancel the vibrations generated by the rotation, thereby reducing vibration. In this way, it is possible to obtain an effect of reducing vibration and reducing noise.

Meanwhile, the first sub-rotation shaft 431 and the second sub-rotation shaft 441 can be rotated by the respective sub motors to the gear box 420. In this case, the rotation of the sub-motor may be reversed so that the rotation of the first aberration 430 and the rotation of the second aberration 440 are opposite to each other.

The first sub-rotation shaft 431 and the second sub-rotation shaft 441 may be connected to the gear box 420 by a bevel gear and may be rotated depending on the main rotation shaft 410. In this case, the pinion gear of the bevel gear may include a first pinion gear connected to the first sub-rotation shaft 431 and a second pinion gear disposed symmetrically with the first pinion gear and coupled to the second sub- Pinion gears.

That is, the second pinion gear may be positioned at a position shifted 180 degrees along the circumferential direction of the first pinion gear. Therefore, the first pinion gear and the second pinion gear, which change the rotational direction by the rotation of the ring gear, can rotate in opposite directions. For example, when the ring gear rotates counterclockwise, as viewed from the outside of the first aberration 430, the first pinion gear rotates counterclockwise, and the second pinion gear rotates clockwise . Therefore, even when the aberration 430.440 is connected by the bevel gear, the rotation of the first aberration 430 and the rotation of the second aberration 440 may be reversed.

Meanwhile, the aberrations 430 and 440 may be positioned in parallel with the main rotation axis 410 in the water tub 300. However, the arrangement angles of the aberrations 430 and 440 are not limited thereto. Specifically, as described above, the sub-rotating shafts 431 and 441 may be connected to the gear box 420 so as to form an acute angle with the main rotating shaft 410.

When the sub rotation shafts 431 and 441 are connected at an acute angle, a first aberration 430 connected to the first sub rotation shaft 431 and a second aberration 440 connected to the second sub rotation axis 441 , And may be positioned so as to be inclined radially upward from the bottom of the water tub (300).

The distance between the first aberration 430 and the second aberration 440 may have a minimum value at the lower end of the first aberration 430 and a lower end of the second aberration 440, .

That is, the aberrations 430 and 440 may be diagonally positioned within the water tub 300 so as to have a predetermined inclination with respect to the main rotation axis 410. In detail, the first aberration 430 and the second aberration 440 may be positioned obliquely to the water surface of the water tank 300. At this time, the second rotation and the third rotation are performed by rotating the first sub-rotation axis 431 and the second sub-rotation axis 441, which have a predetermined inclination so as to form an acute angle with the main rotation axis 410, .

According to this, there is an advantage in that the flow resistance due to the rotation of the water is less than that in the case where the one intake recess angle is vertical when the one recessed space 439 enters the water due to the rotation of the aberration 430.440. Accordingly, when the aberrations 430 and 440 are rotated, the rotation resistance of the fluid is minimized, so that the life of the injector 400 is prolonged and power consumption can be relatively reduced.

In addition, there is an advantage that the area of the droplet to be scattered by the visual body 210 and the humidifying medium 50 can be enlarged by the rotation of the aberration 430.440. That is, the area of the droplet, the height of the droplet, the distance to be reached, the position, and the like scattered in the inner space of the visual body 210 can be increased. Accordingly, the user can confirm that the droplets (droplets) displayed through the visualization windows of the outer visual body 214 and the visual body 210 are uniformly and uniformly provided, thereby maximizing the rain-view effect. As a result, the reliability of the injector 400 for realizing the lane view can be improved.

FIGS. 8 and 9 are conceptual diagrams illustrating a lane view implementation process by an injection device according to an embodiment of the present invention. Hereinafter, a lane view implementation process of the injection device 400 according to the embodiment of the present invention will be described in detail with reference to FIGS. 8 and 9. FIG.

8 and 9, the water stored in the water tank 300 is rotated by the first rotation of the main rotation shaft 410 and the aberrations 430 and 440 along the circumferential direction formed by the circumference of the water tank 300 can do.

The rotationally flowing water is raised to the upper space of the water surface by the second rotation and the third rotation of the aberrations 430 and 440, and is scattered in all directions. For example, the water to be scattered can strike a hemispherical range. At this time, the water scattered by the centrifugal force of the aberrations 430 and 440 is directed to the humidifying medium 50, the visual body 210, and the like. That is, water can be sprayed to the humidifying medium (50), the visual body (210), and the like by the spraying device (400).

When a plurality of aberrators 430 and 440 rotate, the amount of water to be scattered is increased and scattered more widely by mutual collision of water droplets (droplets). That is, the humidifying medium 50, the visual body 210, and the like may be provided with a wider range of water.

The water sprayed by the spraying device 400 may be sprayed toward at least one of the visual body 210 and the humidifying medium 50. Here, the water injected into the visual body 210 may implement a lane view. And the water sprayed toward the humidifying medium 50 can humidify the filtered air.

The water sprayed toward the visual body 210 can be further wetted with the water tank humidifying medium while flowing along the inner surface of the visual body 210 after implementing the rain view in the scattering process.

The water flowing along the visual body 210 and the water supplied to the spraying device 400 may be discharged after being soaked in the water tank humidifying medium and then recovered to the water tank 300 again. The recovered water can be repeated by the rotation of the injector 400 again.

On the inner side of the visual body 210, a plurality of droplets are formed in the form of droplets. The plurality of droplets may flow along the inner surface of the visual body 210 to achieve one configuration of the lane view.

The visual body 210 and the outer visual body 214 are provided as a transparent material so that the user can visually check the rain view, so that the visual body 210 and the outer visual body 214 can be called a visualization window. The water stored in the water tank 300 may be blown in the forward direction by the rotation of the spray device 400, and hit the visualization window. The user can confirm the lane view implemented by the injection device 400 through the visualization window. Here, the visual body 210 may be referred to as a first visualization window, and the outer visual body 214 may be referred to as a second visualization window.

If the water level falls in the water tank 300 and the rain-view implementation becomes difficult, the user can check the amount of water through the visualization window. Then, the user can supply water through the water supply flow path 109. At this time, a rain view can be implemented simultaneously with the supply of water. In detail, the water to be supplied falls again to hit the rotation of the aberrations 430 and 440 to form a fine droplet, and the fine droplet is scattered, so that another configuration of the lane view can be achieved.

In addition, the fine droplets can wash the filtered air once again into the air-wash inlet 31, and can be used for air collection and purification. The filtered air may be discharged to the outside through the discharge passage 107.
