Description

Air sterilization device equipped with UV-C blocking unit

The following description relates to an air sterilization device equipped with a UV-C blocking unit.

In addition to air pollution caused by industrial development, the importance of managing indoor air quality where ventilation is difficult is increasing due to the recent spread of the coronavirus. Installing air purifiers and air sterilizing devices is the most common method used to manage indoor air quality. However, when the UV-C that air purifiers and air sterilizing devices emit to sterilize the air is irradiated directly to people, it causes damage to the skin or cornea due to the short wavelength light source with high energy density. To prevent this, the ceiling-mounted air purifier (JP 1997-038523 A) is equipped with a sterilizing lamp inside the air purifier, and a louver structure is installed on the door to block UV-C from being exposed to the outside of the air purifier. Additionally, the louver structure allows the blades to be tilted at a predetermined angle, thereby blocking UV-C and exhausting air to the outside of the air purifier.

However, in the louver structure, as the angle of the blade increases, the amount of air discharged decreases, which reduces the air volume performance of the air purifier. Therefore, a technology is needed that blocks UV-C and does not reduce the airflow performance of air purifiers or air sterilizing devices.

The above-mentioned background technology is possessed or acquired by the inventor in the process of deriving the disclosure of the present application, and cannot necessarily be said to be known technology disclosed to the general public before the present application.

Hereinafter, an air sterilizing device equipped with a UV-C blocking unit 120 according to embodiments will be described with reference to FIGS. 1 to 3. FIG. 1 is a perspective view of an air sterilizing device 10 according to an embodiment, FIG. 2 is a cross-sectional view of a UV-C blocking unit 120 according to an embodiment, and FIG. 3 is a UV-C blocking unit 120 according to another embodiment. This is a cross-sectional view of the unit 120'.

Air (A) flows inside the housing 100. The housing 100 is formed with an inlet 102 and an outlet 103, and a suction fan F is provided at the inlet 102 to allow air A to flow along the longitudinal direction of the housing 100.

The housing 100 may be installed on the floor or wall.

Additionally, the housing 100 may have a plurality of regions that can be separated and combined according to their roles. For example, the housing 100 may be a member in which the inlet 102 and the outlet 103 and the remaining areas excluding the inlet and

outlet

102 and 103 are formed to be separable and coupled to each other. The housing 100 is made up of a plurality of members, so the size can be adjusted by changing the number of members depending on the installation location, and the members can be separated to facilitate cleaning.

The frame 121 is formed to a size such that the portion of the outer peripheral surface excluding the through surface is in contact with the inside of the housing 100. At this time, the frame 121 can divide the interior of the housing 100 into a UV-C (U) emission area 104 and a UV-C (U) blocking area 105 through the shape of a partition. The frame 121 divides the area of the housing 100 and limits the range in which UV-C(U) emits light to only the light-emitting area 104, thereby allowing UV-C(U) to emit light together with the plurality of blades 122. It is possible to prevent the light emitting area 104 from passing through the UV-C blocking area 105.

The UV-C blocking unit 120 can increase the air sterilization effect by increasing the number of UV-C light-emitting modules. Additionally, the UV-C blocking unit 120 can increase the UV-C blocking effect by increasing the number of UV-C blocking modules.

The plurality of blades 122 are parallel to each other and are formed to block UV-C(U) from being exposed to the outside of the housing 100. For example, the plurality of blades 122 may be curved so that UV-C(U) is irradiated to the side with the largest area. The plurality of blades 122 can directly block UV-C(U), preventing damage caused by using an air purifier or air sterilizing device. Specifically, the plurality of blades 122 can prevent damage from occurring when UV-C comes into contact with the human body. Additionally, the plurality of blades 122 are not limited to the form shown in FIGS. 1 and 2, and may be formed in various shapes that can prevent damage to the human body by blocking exposure to UV-C(U).

The plurality of blades 122 are each installed in a longitudinal direction perpendicular to the wall surface of the frame 121, and may form a plurality of straight flow paths 101 through which air A flows. In this configuration, the plurality of blades 122 cause the air (A) to flow in a straight line through the straight flow path 101, thereby preventing the air (A) from flowing and dispersing due to collision with the structure, thereby preventing the air (A) from flowing and dispersing due to collision with the structure. may not reduce the flow rate. That is, the plurality of blades 122 form a lattice structure with the frame 121 to increase the flow rate of air (A) flowing from the inside to the outside of the housing 100, so that the UV-C blocking unit 120 The air volume of the installed air sterilizing device 10 can be increased.

In addition, the plurality of blades 122 are formed in a shape that facilitates the flow of air (A), so that the flow rate of air (A) does not decrease due to friction when the air (A) flows. For example, the plurality of blades 122 may be formed so that the air resistance coefficient is at least 0.01 and 0.01 or less.
