Abstract
A sterilizer is provided to include: a first pipe having an inner wall with a light reflecting property; a second pipe disposed in the first pipe so as to pass fluid therethrough and formed of a light transmitting material; and a plurality of UV LEDs arranged on the inner wall of the first pipe and configured to irradiate sterilization UV light onto the fluid.
Claims14
A sterilizing device for sterilizing a fluid, comprising:
- a first pipe having a closed region and an open region that are disposed at opposite sides of the first pipe, the open region of the first pipe configured to allow a fluid to enter the sterilizing device for sterilization;
- a second pipe disposed inside the first pipe and having an open region spaced apart from the closed region of the first pipe;
- a light reflector disposed on the first pipe and configured to prevent occurrence of a non-irradiation region of ultraviolet (UV) light within the second pipe;
- and
- a first UV light emitting diode (LED) and a second UV LED that are disposed on the first pipe and configured to irradiate the UV light onto the fluid;
- wherein one of the first UV LED and the second UV LED is positioned within a beam angle of the UV light emitted by the other of the first UV LED and the second UV LED, and
- wherein the closed region of the first pipe is structured to allow the fluid to change a direction of a flow from a first direction to a second direction and the first pipe and the second pipe are configured to increase irradiation time of the UV light per unit volume for the fluid as compared to a case having only one pipe.

A sterilizing device for sterilizing a fluid, comprising:
- a first pipe having a closed region at a first side of the first pipe and having a light reflecting property that reflects ultraviolet (UV) light;
- a second pipe disposed inside the first pipe and structured to provide a passage for a fluid to pass through the second pipe, the second pipe including a light transmitting material to allow the UV light to enter the second pipe;
- a light reflector disposed on the first pipe and arranged to prevent occurrence of a non-irradiation area of the UV light within the second pipe;
- and
- a first UV light emitting diode (LED) and a second UV LED that are disposed on the first pipe and configured to irradiate the UV light onto the fluid;
- wherein the second pipe has an open region that is disposed at one side of the second pipe and spaced apart from the closed region of the first pipe, and
- wherein the closed region of the first pipe is structured to allow the fluid to change a direction of a flow from a first direction to a second direction and the second pipe is configured to increase irradiation time of the UV light per unit volume for the fluid as compared to a case without the second pipe.
