Abstract
An air cleaner is provided to include a photocatalytic UV LED (57) installed on an UV LED substrate (55), and a photocatalytic filter installed on a surface facing the photocatalytic UV LED while being spaced apart from the UV LED substrate. The photocatalytic filter has a structure in which a photocatalytic material is coated on a base in which a plurality of cells (83) defining an air flow path in a direction toward the photocatalytic UV LED are arranged in parallel adjacent to each other.
Claims21
An air cleaner comprising:
- a body having a first housing formed in a lower part of the body and a second housing formed in an upper part of the body;
- an air inlet port formed in the first housing and positioned to introduce air into the body,
- an air flow path positioned to cause the introduced air to flow from the first housing into the second housing along the air flow path;
- a filter disposed in the air inlet port and configured to control air quality of the introduced air;
- a UV LED (ultraviolet light emitting device) disposed in the air flow path and configured to radiate, towards air moving from the lower part to the upper part, ultraviolet light having a sterilization wavelength;
- and
- an outlet disposed in an upper portion of the second housing and configured to discharge air to an outside,
- wherein the air cleaner further comprises a duct disposed between the filter and the outlet, the duct having a flat sidewall and a curved sidewall that is curved such that a cross-sectional area of the duct gradually enlarges along the air flow path.
An air cleaner comprising:
- a body having a first housing formed in a lower part of the body and a second housing formed in an upper part of the body;
- an air inlet port formed in the first housing and operating to introduce air into the body, wherein the introduced air flows along an upward air flow path from the lower part to the upper part of the body;
- a UV LED (ultraviolet light emitting device) disposed in the air flow path and configured to radiate ultraviolet light having a sterilization wavelength toward air moving from the lower part to the upper part;
- a filter disposed above the UV LED and configured to control air quality of air flowing through the second housing;
- a fan disposed below the UV LED;
- and
- wherein the air cleaner further comprises a duct disposed in an upper portion of the fan, the duct having a flat sidewall and a curved sidewall that is curved such that a cross-sectional area of the duct gradually enlarges along the air flow path.
