Abstract

A clothes treating apparatus includes a case including a treatment chamber for holding clothes, a steam unit for supplying steam to the treatment chamber, a tank module storing water to be supplied to the steam unit, a valve unit disposed in a flow channel connecting the tank module and the steam unit, a water supply pump for generating driving power to transmit water stored in the tank module to the steam unit, and a control unit controlling the steam unit and the water supply pump, wherein the valve unit opens or closes the flow channel by at least one of water and steam flowing in the flow channel.

First claim

What is claimed is:

1. A clothes treating apparatus comprising:
a case including a treatment chamber for holding clothes;
a steam unit configured to supply steam to the treatment chamber;
a storage tank storing water to be supplied to the steam unit;
a valve unit disposed in a flow channel connecting the storage tank and the steam unit,
wherein the valve unit includes a main body, a ring protruding from an inner circumferential surface of the main body, a rod member provided to be movable within the ring of the main body having a hollow portion, and a sealing member to close the hollow portion of the ring by attaching to the ring;
a water supply pump configured to transmit water stored in the storage tank to the steam unit; and
a control unit controlling the steam unit and the water supply pump,
wherein the valve unit opens or closes the flow channel by at least one of water and steam flowing in the flow channel,
wherein the rod member includes:
a first part, a second part, and a third part,
wherein the first part is provided at one end of the rod member adjacent to the storage tank and is caught by one surface of the ring when water is supplied,
wherein the third part is provided at the other end of the rod member adjacent to the steam unit and supports the sealing member so that the sealing member is caught by a surface different from the one surface of the ring when steam is generated,
wherein the second part is connected to the first part and the third part and includes a damper fixing the sealing member, and
wherein a width of the second part is smaller than a diameter of an inner circumferential surface formed by the ring, and

wherein the sealing member comprises:
a first plate, and
a second plate formed to be thicker than the first plate and to be positioned on a side surface of the first plate adjacent to the third part.

2. The clothes treating apparatus of claim 1 , wherein when the water supply pump operates, the flowing water in the flow channel causes the valve unit to open.

3. The clothes treating apparatus of claim 1 , wherein when the steam unit generates steam, the steam causes the valve unit to close.

4. The clothes treating apparatus of claim 1 , wherein the valve unit is a mechanical valve operating independently from the control unit.

5. The clothes treating apparatus of claim 1 , wherein the valve unit is implemented in
a first state in which the rod member moves toward the steam unit within the hollow portion to open the hollow portion to allow water supplied from the storage tank to flow, and
a second state in which the rod member moves toward the storage tank within the hollow portion to close the hollow portion to prevent a backflow of steam generated by the steam unit.

6. The clothes treating apparatus of claim 5 , wherein the valve unit has a cylindrical shape and further comprises:
a first rib protruding from one surface of the ring in a flow direction of water.

7. The clothes treating apparatus of claim 5 , wherein the first part of the rod member includes:
at least one hole; and
a hook provided to be caught by the ring.

8. The clothes treating apparatus of claim 7 , wherein the hole is provided on an inner circumferential surface of the hook.

9. The clothes treating apparatus of claim 7 , wherein when the water supply pump operates, the hook rests on one surface of the ring adjacent to the storage tank.

10. The clothes treating apparatus of claim 5 , wherein the first part of the rod member is elastically deformed by an external force.

11. The clothes treating apparatus of claim 5 , wherein one surface of the first part of the rod member is formed to be gentle to minimize resistance with respect to water flowing in the flow channel.

12. The clothes treating apparatus of claim 11 , wherein one end of the first part of the rod member adjacent to the storage tank is narrower than the other end of the first part adjacent to the steam unit.

13. The clothes treating apparatus of claim 11 , wherein a width of one end of the first part of the rod member adjacent to the storage tank is smaller than a diameter of a circle formed by the ring, and a width of the other end of the first part of the rod member adjacent to the steam unit is larger than the diameter of the circle.

14. The clothes treating apparatus of claim 1 , wherein a portion of the flow channel in which the valve unit is provided is formed in a vertical direction with respect to the ground, and
wherein the valve unit is implemented in
a first state in which the rod member moves downwards within the hollow portion to open the hollow portion to allow water supplied from the storage tank to flow when the steam unit is stopped, and
a second state in which the rod member moves upwards within the hollow portion to close the hollow portion to prevent a backflow of steam generated by the steam unit when the steam unit operates.

15. The clothes treating apparatus of claim 14 , wherein the rod member is positioned on a lower side within the hollow portion due to gravity when both the water supply pump and the steam unit are stopped.

16. The clothes treating apparatus of claim 15 , wherein when steam is generated by the steam unit, the rod member moves upwards within the hollow portion by air pressure of the generated steam.

17. The clothes treating apparatus of claim 1 , wherein the sealing member is formed to close the hollow portion by attaching to the surface different from the one surface of the ring adjacent to the steam unit, when the rod member moves toward the storage tank due to air pressure of steam generated by the steam unit.
