Abstract

In one aspect, a sterilization apparatus is provided to include a flow channel body comprising an inflow unit configured to provide an inflow channel through which water flows in one direction, a discharge unit configured to provide a discharge channel through which water is discharged, and a bypass channel unit configured to provide a bypass channel through which water bypasses in a different direction from the direction of the water flowing in the inflow unit; a mounting unit formed on the flow channel body and configured to provide an installation space connected to the bypass channel, a UV light emitting unit disposed in the installation space and configured to emit UV light towards the bypass channel; and a holder coupled to the mounting unit and securing the UV light emitting unit inside the mounting unit.

First claim

We claim:

1. A sterilization module comprising:
a main body having an opening at upper and lower sides of the main body;
a protective cover disposed inside the main body to shield an interior of the main body from an outside of the main body, the protective cover including a material through which UV light transmits;
a substrate secured to an inner wall of the main body and disposed on the protective cover; a cover seat protruding inward from an inner surface of the main body such that the protective cover is seated on the cover seat;
an UV light emitting unit disposed on an upper surface of the substrate and configured to emit UV light towards the protective cover;
a spacer disposed between the substrate and the protective cover and configured to separate the UV light emitting unit from the protective cover;
an inner sealing member disposed between an upper surface of the cover seat and a lower surface of the protective cover to seal a gap between the main body and the protective cover; and
an electronic component disposed on the upper surface of the substrate,
wherein one end of the spacer is in contact with the upper surface of the substrate, and the other end of the spacer is in contact with the lower surface of the protective cover,
wherein the spacer is separated from the UV light emitting unit, and a separation space is formed between the spacer and the UV light emitting unit, and
wherein the electronic component is disposed in the separation space between the spacer and the UV light emitting unit.

2. The sterilization module of claim 1 , further comprising:
a cable detachably coupled to the electronic component,
wherein one end of the cable is detachably coupled to electronic component and the other end of the cable is connected to an external power device, and
wherein the electronic component is a connector, and the connector is electrically connected to the substrate.

3. The sterilization module of claim 1 , wherein the spacer has a displacement preventing portion protruding upward from an upper surface of the spacer and preventing the substrate from being displaced from a designated place,
wherein the displacement preventing portion has a height less than or equal to a thickness of the substrate.

4. The sterilization module of claim 1 , further comprising:
a substrate seat protruding inward from an inner wall of the spacer to allow the substrate to be seated on the substrate seat.

5. The sterilization module of claim 4 , further comprising:
a substrate holding portion disposed on the substrate and fastened to the inner wall of the main body.

6. The sterilization module of claim 1 , further comprising:
a body holding portion formed along an outer periphery of the main body and protruding from an outer surface of the main body.

7. A sterilization module comprising:
a main body having an opening at upper and lower sides of the main body;
a protective cover disposed inside the main body to shield an interior of the main body from an outside of the main body, the protective cover including a material through which UV light transmits;
a substrate secured to an inner wall of the main body and disposed on the protective cover;
a cover seat protruding inward from an inner surface of the main body such that the protective cover is seated on the cover seat;
an UV light emitting unit disposed on an upper surface of the substrate and configured to emit UV light towards the protective cover;
an inner sealing member disposed between an upper surface of the cover seat and a lower surface of the protective cover to seal a gap between the main body and the protective cover;
an outer holder fastened to an outer wall of the main body;
an outer sealing member to seal a gap between the main body and the outer holder;
an electronic component disposed on the upper surface of the substrate,
a spacer disposed between the substrate and the protective cover and configured to separate the UV light emitting unit from the protective cover;
wherein one end of the spacer is in contact with the upper surface of the substrate, and the other end of the spacer is in contact with the lower surface of the protective cover,
wherein the spacer is separated from the UV light emitting unit, and a separation space is formed between the spacer and the UV light emitting unit, and
wherein the electronic component is disposed in the separation space between the spacer and the UV light emitting unit.

8. The sterilization module of claim 6 , further comprising:
an outer holder fastened to an outer wall of the main body.

9. The sterilization module of claim 8 , further comprising:
an outer sealing member disposed between an upper surface of the body holding portion and a lower surface of the outer holder to seal a gap between the main body and the outer holder.

10. The sterilization module of claim 7 , wherein the cover seat has a tapered shape having a diameter gradually increasing towards a lower surface of the cover seat.

11. The sterilization module of claim 7 , further comprising:
a cable detachably coupled to the electronic component,
wherein one end of the cable is detachably coupled to the electronic component and the other end of the cable is connected to an external power device, and
wherein the electronic component is a connector, and the connector is electrically connected to the substrate.

12. The sterilization module of claim 7 , further comprising:
a substrate holding portion disposed on the substrate and fastened to the inner wall of the main body.

13. A sterilization module comprising:
a main body having an opening at upper and lower sides of the main body;
a protective cover disposed inside the main body to shield an interior of the main body from an outside of the main body, the protective cover including a material through which UV light transmits;
a substrate secured to an inner wall of the main body and disposed on the protective cover;
a cover seat protruding inward from an inner surface of the main body such that the protective cover is seated on the cover seat;
an UV light emitting unit disposed on an upper surface of the substrate and configured to emit UV light towards the protective cover; and
an inner sealing member disposed between an upper surface of the cover seat and a lower surface of the protective cover to seal a gap between the main body and the protective cover;
a spacer disposed between the substrate and the protective cover and configured to separate the UV light emitting unit from the protective cover; and
an electronic component disposed on the upper surface of the substrate,
wherein one end of the spacer is in contact with the upper surface of the substrate, and the other end of the spacer is in contact with the lower surface of the protective cover,
wherein the spacer is separated from the UV light emitting unit, and a separation space is formed between the spacer and the UV light emitting unit,
