Abstract

An apparatus for automatically drying wet floors includes a floor mat; a controller; a detector mat that is positioned adjacent to the floor mat, the detector mat having at least one moisture sensing element that is operable to detect moisture and transmit a moisture detection signal to the controller in response to detecting the presence of moisture at the first location, and a floor dryer that is operative to turn on and off for drying the floor mat by directing moving air toward the floor mat in response to an operating signal from the controller, wherein the controller outputs the operating signal to the blower based on the moisture detection signal.

Claims

1. An apparatus for automatically drying wet floors, comprising:

a floor mat;

a controller;

a detector mat that is positioned adjacent to the floor mat, the detector mat having at least one moisture sensing element that is operable to detect moisture and transmit a moisture detection signal to the controller in response to detecting the presence of moisture at the first location; and

a floor dryer that is operative to turn on and off for drying the floor mat by directing moving air toward the floor mat in response to an operating signal from the controller, wherein the controller outputs the operating signal to the blower based on the moisture detection signal.

2. The apparatus of claim 1, wherein the detector mat includes a body and the at least one moisture sensing element includes a plurality of electrodes that are disposed on the body.

3. The apparatus of claim 2, wherein the body of the detector mat is liquid impervious.

4. The apparatus of claim 2, wherein the body of the detector mat includes a plurality of channels that are recessed with respect to a top surface of the detector mat.

5. The apparatus of claim 4, wherein at least some of the electrodes are positioned along the channels.

6. The apparatus of claim 5, wherein at least some of the electrodes have a first portion positioned on a wall of one of the channels and a second portion positioned on the top surface of the detector mat.

7. The apparatus of claim 4, wherein the channels are formed in a first portion of the detector mat and the floor mat is positioned such that it overlies a second portion of the detector mat.

8. The apparatus of claim 7, wherein the floor mat includes a backing layer and a carpet layer that is disposed on the backing layer.

9. The apparatus of claim 7, wherein the first portion of the detector mat is thicker than the second portion of the detector mat.

10. The apparatus of claim 7, wherein the second portion of the detector mat is tapered with respect to the first portion of the detector mat.

11. An apparatus for automatically drying wet floors, comprising:

a floor mat having a backing layer and a carpet layer that is disposed on the backing layer;

a controller;

a detector mat that is positioned adjacent to the floor mat, the detector mat having at least one moisture sensing element that is operable to detect moisture and transmit a moisture detection signal to the controller in response to detecting the presence of moisture at the first location, wherein the detector mat includes a body that is liquid impervious, the at least one moisture sensing element includes a plurality of electrodes that are disposed on the body, the body of the detector mat includes a plurality of channels that are recessed with respect to a top surface of the detector mat, and at least some of the electrodes are positioned along the channels; and

a floor dryer that is operative to turn on and off for drying the floor mat by directing moving air toward the floor mat in response to an operating signal from the controller, wherein the controller outputs the operating signal to the blower based on the moisture detection signal.

12. The apparatus of claim 11, wherein at least some of the electrodes have a first portion positioned on a wall of one of the channels and a second portion positioned on the top surface of the detector mat.

13. The apparatus of claim 11, wherein the channels are formed in a first portion of the detector mat and the floor mat is positioned such that it overlies a second portion of the detector mat.

14. The apparatus of claim 13, wherein the first portion of the detector mat is thicker than the second portion of the detector mat.

15. The apparatus of claim 13, wherein the second portion of the detector mat is tapered with respect to the first portion of the detector mat.

16. A detector mat for detecting moisture, comprising:

a body that is liquid impervious and includes a plurality of channels that are recessed with respect to a top surface of the body; and

at least one moisture sensing element that is operable to detect moisture and output a moisture detection signal in response to detecting the presence of moisture at the first location, wherein the at least one moisture sensing element includes a plurality of electrodes that are disposed on the body and at least some of the electrodes are positioned along the channels of the body.

17. The detector mat of claim 16, wherein at least some of the electrodes have a first portion positioned on a wall of one of the channels and a second portion positioned on the top surface of the detector mat.

18. The detector mat of claim 16, wherein the channels are formed in a first portion of the detector mat and a second portion of the detector mat is free of channels.

19. The detector mat of claim 18, wherein the first portion of the detector mat is thicker than the second portion of the detector mat.

20. The detector mat of claim 18, wherein the second portion of the detector mat is tapered with respect to the first portion of the detector mat.
