Abstract

The present invention discloses a clogging detecting system for a dryer which can display a clogging degree or state of an air passage to the user through a remote controlling device. The clogging detecting system for the dryer includes the dryer for judging the clogging degree of the air passage, and sending the clogging degree to a remote controlling device, and the remote controlling device for receiving the clogging degree from the dryer, and displaying the clogging degree through a display unit.

Claims

1. A clogging detecting system for a dryer, comprising:

the dryer for judging a clogging degree of an air passage, and sending the clogging degree to a remote controlling device; and

the remote controlling device for receiving the clogging degree from the dryer, and displaying the clogging degree through a display unit.

2. The clogging detecting system of claim 1, wherein the remote controlling device sends a request command for the clogging degree of the air passage to the dryer, and the dryer judges and sends the clogging degree of the air passage to the remote controlling device.

3. The clogging detecting system of either claim 1 or 2, wherein the remote controlling device comprises an input unit for acquiring the request command for the clogging degree of the air passage from the user.

4. The clogging detecting system of claim 1, wherein the dryer comprises an input unit for acquiring a request command for the clogging degree of the air passage from the user.

5. The clogging detecting system of claim 1, wherein the dryer and the remote controlling device perform power line communication or radio frequency communication.

6. The clogging detecting system of claim 1, wherein the display unit visibly or audibly displays the clogging degree.

7. The clogging detecting system of claim 1, wherein the display unit displays the clogging degree by at least two steps.

8. The clogging detecting system of claim 7, wherein, when the clogging degree is over a critical step, the display unit displays a warning message.

9. The clogging detecting system of claim 1, wherein the display unit displays a clogging degree of a lint filter and a clogging degree of an exhaust duct.

10. An interface device for a remote controlling device, comprising:

a communication means for receiving a clogging degree of an air passage from a dryer; and

a display means for displaying the clogging degree.

11. The interface device of claim 10, comprising a control means for applying a display signal corresponding to the received clogging degree to the display means.

12. The interface device of claim 10, comprising a user input means for requesting the clogging degree of the air passage to the dryer.

13. The interface device of claim 10, wherein the display means displays the clogging degree by at least two steps.

14. The interface device of claim 13, wherein, when the clogging degree is over a critical step, the display means displays a warning message.

15. The interface device of claim 10, wherein the display means displays a clogging degree of a lint filter and a clogging degree of an exhaust duct.

16. The interface device of claim 10, wherein the display means displays a presumed energy consumption amount corresponding to the clogging degree.

17. A remote controlling device, comprising:

a communication means for performing communication with a dryer;

a control means for controlling the communication means to receive a clogging degree of an air passage from the dryer; and

a display means interworking with the control means, for displaying the clogging degree.

18. The remote controlling device of claim 17, wherein the control means converts the clogging degree into a display signal, and applies the display signal to the display means.

19. The remote controlling device of claim 17, wherein the control means computes a presumed energy consumption amount corresponding to the clogging degree, and displays the presumed energy consumption amount on the display means.

20. The remote controlling device of claim 17, comprising an input means for acquiring a request command for the clogging degree of the air passage from the user.
