An air flow path 113 is formed between the air inlet 111 and the air outlet 112 so that the air sucked from the air inlet 111 can be discharged to the air outlet 112 through the ultraviolet lamp 140.

In other words, the ultraviolet lamp 140 is disposed on the air passage 113, and can expose the air to ultraviolet rays.

The filter unit 150 is disposed inside the housing 110 to purify the air flowing into the housing 110.

The filter portion 150 may be disposed adjacent to the air inlet 111. For example, the filter unit 150 is disposed inside the inlet port 111, so that air having passed through the inlet port 111 can be introduced into the interior of the housing 110 through the filter unit 150 .

The filter unit 150 may include various filters such as a pre-filter, a deodorizing filter, a sterilizing filter, and a functional filter, and may include a plurality of filters.

In addition, the ion generating part 160 may be disposed inside the housing 110 to supply ions to the air discharged to the outside of the housing 110.

The ion generating part 160 can generate negative ions by applying a high-voltage current to the charge plate to decompose the oxygen contained in the air. It is possible to add anion to the ultraviolet sterilized air to enhance the sterilizing effect, to remove odors, to provide an air purification function, and the like.

The ion generating portion 160 may be disposed adjacent to the exhaust port 112. For example, the ion generating part 160 is disposed inside the exhaust port 110, so that air passing through the ion generating part 160 can be exhausted to the exhaust port 110.

For example, the intake fan 170a may be disposed inside the filter unit 150, and the exhaust fan 170b may be disposed inside the ion generator 160. [ The air passes through the intake port 111, the filter section 150 and the intake fan 170a in order and the exhaust fan 170b, the ion generating section 160 and the exhaust port 112 via the ultraviolet lamp 140 It can pass.

A reflection plate 180 may be disposed on the inner surface of the housing 110. The reflection plate 180 includes a material reflecting light and may be disposed to surround the inner surface of the housing 110. [

Ultraviolet rays generated from the ultraviolet lamp 140 may be reflected by the reflector 180. As a result, the concentration of ultraviolet rays is improved and the air sterilization effect can be improved.

FIG. 5 shows the shape of the vortex forming portions 190a and 190b according to one embodiment, and FIG. 6 shows the shapes of the vortex forming portions 190a and 190b according to another embodiment.

5 and 6, vortex generators 190a and 190b are formed on the air passage 113 so that a vortex is formed in the air introduced into the housing 110, Or the air intake amount may increase.

In other words, the vortex generators 190a and 190b can be configured so that the air introduced through the inlet port 111 passes through the air passage 113 while forming a vortex, and accordingly, the time for exposing the air to ultraviolet rays increases So that the air sterilization effect can be improved.

The vortex generators 190a and 190b may include vortex protrusions 190a protruding from the inner surface of the housing 110. [ The vortex protrusions 190a may be formed in a plurality of alternately arranged on the upper and lower sides of the inner surface of the housing 110, or may form a certain pattern on the inner surface of the housing 110.

The air passing through the air passage 113 collides with the vortex protrusion 190a and thus the movement path of the air is changed or a vortex is formed and the time for the air to stay in the housing 110 may increase.

The vortex generators 190a and 190b may include vortex guides 190b that extend in the direction of the air passage 113 and are formed to be inclined with respect to the inner surface of the housing 110. [

For example, the vortex guide 190b installed at the lower portion of the housing 110 moves the air upward, and the vortex guide 190b installed at the upper portion of the housing 110 can move the air downward.

A vortex may be generated while air is guided by the vortex guide 190b, or a vortex may be formed as the guided air collides with each other. Accordingly, the time for which air stays in the housing 110 may increase, or the air may be guided toward the ultraviolet lamp 140 to improve sterilization efficiency.

7 is a cross-sectional view of a housing showing a flow guide according to an embodiment.

7, the flow path guide 113c can selectively change the air flow path 113, and the length of the air flow path 113 can be increased or decreased by the flow path guide 113c.

For example, in the initial state, the air introduced from the intake port 111 may be discharged to the exhaust port 112 through the first air flow path 113a.

The flow guide 113c is rotatably installed in the housing 110. When the flow guide 113c is rotated, the flow guide 113c blocks at least a part of the first air flow path 113a, The flow path 113a and the second air flow path 113b can be connected.

For example, the second air passage 113b may be connected to one side of the first air passage 113a, extend in the longitudinal direction of the inside of the housing 110, and then be connected to the other side of the first air passage 113a have.

Thus, the air introduced from the air inlet 111 passes through the first air passage 113a and the second air passage 113b and is discharged to the air outlet 112, so that the time during which the air stays in the housing 110 can be increased have.

The description of the flow path guide 113c, the first air flow path 113a and the second air flow path 113b described above is merely illustrative. If the flow path can be selectively changed, the flow path guide 113c, The first air passage 113a and the second air passage 113b may be formed.

For example, the first air passage 113a and the second air passage 113b are formed inside the housing 110, and the air introduced from the air intake port 111 by the flow guide 113c flows into the first air passage (113a) or the second air passage (113b).

8 is a cross-sectional view schematically showing the inside of the housing 210 according to another embodiment.

Hereinafter, the components included in the above embodiments and the components including the common functions will be described using the same names. Unless otherwise stated, the description of the above embodiment can be applied to the following embodiments. A detailed description will be omitted below.

For example, the housing 210 may include a first area A1 adjacent to the intake port 211 and a second area A2 connected to the first area A1.

The size of the cross section of the second area A2 may be larger than the size of the cross section of the first area A1. In other words, the cross section of the center portion of the housing 210 can be formed larger than the cross section of the intake port 211 into which the air flows.

When a certain amount of air is introduced into the housing 210, the flow rate can be reduced as the cross-sectional size increases. That is, since the flow velocity in the body of the housing 210 is reduced more than the portion of the inlet 211, the time for exposing the air to ultraviolet rays is increased, and ultraviolet sterilization efficiency can be improved.

The housing 210 may include a third region A3 adjacent to the exhaust port 212 and the third region A3 may be connected to the second region A2. The size of the cross section of the second area A2 may be larger than the size of the cross section of the third area A3.

When a certain amount of air moves, the flow velocity may increase as the cross-sectional size decreases from the second region A2 to the third region A3. That is, since the flow velocity increases at the portion of the exhaust port 212 rather than the body of the housing 210, the sterilized air can be quickly discharged.
