Abstract
A sterilizer may 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.
Claims20
A sterilizing device for sterilizing a fluid, comprising:
- a first pipe having a closed end 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 inside 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 inside of 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,
- wherein the second pipe has an open end that is disposed at one side of the second pipe and spaced apart from the closed end of the first pipe, and
- wherein the closed end 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 cause the fluid to flow along the second direction in a space between the first pipe and the second pipe.

A sterilizing device for sterilizing a fluid, comprising:
- a first pipe having a closed end and an open end that are disposed at opposite sides of the first pipe, the open end 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 end disposed at one side of the second pipe and spaced apart from the closed end of the first pipe;
- a light reflector disposed inside the first pipe and arranged to prevent occurrence of a non-irradiation area of ultraviolet (UV) light within the second pipe;
- and
- a first UV light emitting diode (LED) and a second UV LED that are disposed inside of 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 end 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 cause the fluid to flow along the second direction in a space between the first pipe and the second pipe.
