The air inlet 4 of the air cleaner of the present embodiment is not exposed to the outside. Therefore, the user cannot confirm the air intake port 4 from the outside. In particular, since the air inlet 4 is not exposed to the outside of the upper case 10 or the lower case 6, the degree of freedom in the design of the air cleaner is high.
The air inlet of the existing air purifier is exposed to the outside, so the existing air purifier is restricted when in appearance design. In particular, in the conventional air cleaner, a suction grill or a filter is provided at an air inlet, and there is a problem that the appearance is contaminated due to dust and the like accumulated on the suction grill or the filter. However, in the air cleaner of the present embodiment, the air inlet 4 is hidden, and therefore, no dust or the like is deposited on the external appearance of the air cleaner.
The operation of the present invention will be described below.
First, when the air cleaner is operated, the blower 60 and the humidification filter rotation unit 3 are driven.
The humidification filter rotating unit 3 drives a motor 3E.
When the motor 3E is driven, the filter assembly is rotated.
When the motor 3E is driven, the driving gear 3D rotates the driven gear 3C.
The filter cover 3B rotates together with the driven gear 3C, and the humidification filter 2 provided on the rotation shaft 3A rotates.
When the humidification filter 2 rotates, the portion of the humidification filter 2 immersed in the water tank 1 rises and is exposed to the air. In addition, when the humidification filter 2 rotates, the portion exposed to the air is soaked in the water tank 1. The humidifying filter 2 repeats this operation.
When the motor 62 of the blower 60 is driven, the air outside the air cleaner is sucked into the air suction flow path P1 formed in the lower case 6 through the slit T1.
The outside air flows upward along the air intake flow path P1.
The air sucked into the air suction flow path P1 is sucked into the lower case 6 through the air suction port 4.
The air having passed through the air inlet 4 flows to the blower 60 and contacts the humidification filter 2. The air in contact with the humidification filter 2 can attach foreign matters in the air to the humidification filter 2. At the same time, the air in contact with the humidification filter 2 can evaporate the water of the humidification filter 2.
The evaporated moisture flows toward the blower 60 together with the flowing air.
The air flowing toward the blower 60 is purified while passing through the internal filter 80.
The blower 60 causes the air filtered by the internal filter 80 to flow upward. The air flowing by the air blower 60 passes through the discharge grill 15 and is then discharged to the outside through the air discharge flow path P2.
Fig. 5 is a sectional view showing an air cleaner according to a second embodiment of the present invention.
The air cleaner of the present embodiment includes a humidification filter 200 soaked in the water tank 1 instead of the humidification filter rotating unit 3.
The humidification filter 200 may be formed of a porous material.
The air flowing through the blower 60 can flow through the humidification filter 200.
The air passes through the humidifying filter 200 while being humidified.
The humidifying filter 200 of the present embodiment is formed in a cylindrical shape with an empty interior. The humidification filter 200 may be modified into various shapes according to design.
A part of the lower side of the humidifying filter 200 is immersed in the water tank 1.
The humidification filter 200 absorbs water in a portion immersed in the water tank 1 and can move the water upward. The movement of the water in the humidification filter 200 may be achieved by surface tension.
The humidification filter 200 is provided on a flow path of the blower 60.
The humidifying filter 200 may be separately provided. In this embodiment, disposed inside the inner housing 270.
The inner case 270 forms an air passage 271 for connecting the air intake port 4 and the blower 60. The air passage 271 is formed inside the inner case 270.
An inner suction port 274 for communicating with the air suction port 4 is formed in the inner case 270. The air sucked through the interior suction port 274 passes through the humidification filter 200.
The humidification filter 200 shields the interior suction port 274.
The humidification filter 200 is closely attached to the inner surface of the inner case 270.
In the case where the inner case 270 is not provided, the air may flow to the blower 60 after contacting the surface of the humidification filter 200 without passing through the humidification filter 200. That is, the air sucked through the air inlet 4 does not necessarily have to flow through the humidification filter 200.
In the present embodiment, in order to improve the humidification performance, the humidification filter 200 is configured to pass air flowing therethrough.
The inner suction port 274 is formed in the inner case 270 in a horizontal direction.
The inner housing 270 includes an inner support 275 that rests on the filter support 5. The inner support 275 is formed to protrude outward from the inner case 270.
In the present embodiment, the humidification filter 200 and the inner case 270 are integrally manufactured, and the integrated humidification filter 200 and the inner case 270 are defined as the humidification module 210.
The humidifying unit 210 is disposed to be spaced upward from the water tub 1 by an inner support 275 mounted on the filter support 5.
That is, the humidifying unit 210 is disposed inside the water tank 1 with a space. This also facilitates the inflow of water into the humidifying filter 200.
It is also possible to separately manufacture the humidification filter 200 and the inner case 270, differently from the present embodiment.
The air purifier of the present embodiment may be separated into at least three parts.
For example, the upper case 10, the humidifying unit 210, and the lower case 6, which are provided with the blower 60, may be separated.
The user can separate only the upper housing 10 from the air cleaner. The humidifying module 210 can be additionally separated from the air cleaner from which the upper case 10 is separated. In addition, only the water tank 1 may be additionally separated from the air cleaner from which the humidifying module 210 is separated.
The air cleaner of the present embodiment is different from the first embodiment in that only the blower 60 is driven without the humidification filter rotation unit 3.
Hereinafter, the operation of the air cleaner of the present embodiment will be described in more detail with reference to the drawings.
The humidifying assembly 210 soaked in the water tank 1 absorbs the water of the water tank 1 and moves it to the upper side.
The air is driven by the blower 60 to flow into the air cleaner.
By the driving of the blower 60, the outside air is sucked into the air suction flow path P1 formed in the lower case 6 through the slit T1. The outside air flows along the air intake flow path P1, and flows into the lower housing 6 through the air intake port 4.
The air sucked into the lower case 6 flows into the inner case 270 through the inner suction port 274. At this time, the air flows through the humidification filter 200 located inside the inner case 270. In the process, humidification of the air is achieved.
The air flowing into the humidifying filter 200 flows along the inside of the inner case 270 toward the blower 60.
The blower 60 discharges the humidified air to the outside by flowing the air to the air discharge port 8.
The remaining structure is the same as that of the first embodiment, and thus detailed description thereof is omitted.
Fig. 6 is a partially cut-away perspective view showing a lower case of a third embodiment of the present invention.
The lower case 306 of the present embodiment is different from the first embodiment in that the entire portion between the inner body portion 20 and the outer body portion 30 forms the air suction port 4.
The air suction opening 4 is located at the upper ends of the inner and outer body portions 20 and 30.
The bridge 342 for connecting the inner body portion 20 and the outer body portion 30 is located at a lower side of the air suction port 4.
The bridge portion 342 is formed in a rib shape.
The bridge portion 342 is formed long in the vertical direction. The bridge portion 342 formed in the up-down direction can minimize the resistance of the air flowing along the air intake flow path P1.
The remaining structure below is the same as that of the first embodiment, and thus detailed description thereof is omitted.
Fig. 7 is a perspective view showing a lower case of a fourth embodiment of the present invention.
Unlike the first embodiment, the air suction port 404 of the lower housing 406 of the present embodiment is formed in the inner body portion 20.
The upper ends of the inner body 20 and the outer body 30 are shielded by the connecting portion 40.
The air suction inlet 404 is formed in a horizontal direction.
The remaining structure is the same as that of the first embodiment, and thus detailed description thereof is omitted.
It will be apparent to those skilled in the art that the present invention can be embodied in other specific forms without departing from the spirit or essential characteristics thereof. Accordingly, the embodiments described above are exemplary only, and not limiting. The scope of the present invention is defined by the scope of the claims, and includes all modifications and variations derived from the meaning and scope of the claims and their equivalent concepts.
