Abstract

A wash station comprises a sink and a faucet. A source of water and a source of soap are provided. An electrically operated valve is interposed between the water source and the faucet for selectively supplying water thereto, and a pump and valve are interposed between the soap source and the faucet for selectively supplying soap thereto. An electrically operated roll towel dispenser is disposed proximate the sink. A first infrared sensor is operably associated with the sink for determining the presence of a user. A control mechanism is operatively associated with the valves, the pump, the roll towel dispenser and the sensor for causing water and soap to be selectively supplied to the faucet and for thereafter causing a length of roll towel to be dispensed.

Claims

1. A wash station, comprising:

a) receptacle means for receiving fluids;

b) a source of water;

c) a source of cleansing means;

d) first means interposed between said water source and said receptacle means for selectively supplying water thereto, and second means interposed between said cleansing means source and said receptacle means for selectively supplying cleansing means;

e) towel dispensing means proximate said receptacle for dispensing a length of continuous roll towel means;

f) first sensor means operatively associated with said receptacle means for determining the presence of a user; and

,

g) electronic control means operatively associated with said first and second means, said towel dispensing means, and said sensor means for electronically and selectively causing a supply of water and cleansing mans to be supplied to said receptacle means and for thereafter causing a length of roll towel means to be dispensed.

2. The wash station of claim 1, wherein:

a) means being operably associated with said source of cleansing means for determining the quantity of cleansing means in said source.

3. The wash station of claim 2, wherein:

a) said source of cleansing means includes a bottle in which the cleansing means is contained; and

,

b) said determining means being disposed below and engaged with said bottle.

4. The wash station of claim 3, wherein:

a) said determining means comprising a pressure actuated switch.

5. The wash station of claim 3, wherein said determining means includes:

a) first and second hingedly connected members, said first member overlying said second member; and

,

b) a pressure actuated switch being disposed between said members so that the weight of the bottle is applied to said switch while resting on said first member.

6. The wash station of claim 1, wherein said second means includes:

a) pump means having an inlet communicating with said source of cleansing means, and an outlet communicating with said receptacle means.

7. The wash station of claim 6, wherein:

a) said pump means having a continuous resilient conduit interconnecting said inlet and said outlet, and said conduit being removable from said pump means.

8. The wash station of claim 6, wherein said pump means includes:

a) an outer substantially non-deformable shell having an opening therein;

b) a resilient bladder positioned within said shell, said bladder having a central opening aligned with said inlet and said outlet and an annular chamber communicating with said shell opening;

c) means interconnecting said shell opening and said source of water; and

,

d) valve means operably associated with said interconnecting means cooperating with said control means so that water is selectively introduced into said annular chamber for causing said chamber to expand and thereby said central opening to be collapsed so that cleansing means contained within said central opening is caused to be dispensed to said receptacle means.

9. The wash station of claim 8, wherein:

a) a resilient continuous conduit extending through said central opening between said inlet and said outlet, said conduit being removable from said central opening.

10. The wash station of claim 9, wherein:

a) said conduit extending between said source of cleansing means and said receptacle.

11. The wash station of claim 1, further comprising:

a) selector switch means being operably connected with said control means, said selector switch means having first and second positions so that said control means prohibits the supply of cleansing means to said receptacle means when said selector switch means is in said first position.

12. The wash station of claim 1, further comprising:

a) second sensor means being operably associated with said source of continuous roll towel means and with said control means; and

,

b) said control means including means causing toweling to be dispensed when said second sensor means has detected the presence of a user.

13. The wash station of claim 1, wherein:

a) counter means being operably associated with said control means for monitoring use thereof.

14. The wash station of claim 1, wherein said receptacle means includes:

a) a faucet having first and second flow channels;

b) said first flow channel being in fluid communication with said first means, and said second flow channel being in fluid communication with said second means.

15. The wash station of claim 7, wherein said pump means includes:

a) a motor driven rotary pump having a rotating shaft carrying a plurality of vanes;

b) a removable cover surrounding said shaft; and

,

c) said conduit being disposed between said cover and said vanes, so that rotation of said shaft causes said vanes to cyclicly engage and compress said conduit.

16. The wash station of claim 14, wherein:

a) said second flow channel being surrounded by said first flow channel.

28. The wash station of claim 16, wherein:

a) one of said flow channels being surrounded by the other of said flow channels.

17. A wash station, comprising:

a) a support assembly comprising a lower cabinet having an interior and an upper vertical structure;

b) a motor operated roll towel dispensing means mounted to said upper member, and a roll of toweling being operatively disposed within said dispenser;

c) a sink mounted to said cabinet below said dispensing means;

d) a faucet mounted to said cabinet and extending over said sink, said faucet having first and second flow channels discharging into said sink;

e) a source of water mounted within said cabinet;

f) a supply of soap disposed within said cabinet;

g) first means interconnecting said source and one of said flow channels for permitting water to selectively flow to said faucet, and second means interconnecting said supply and the other of said flow channels for causing soap to be supplied to said faucet;

h) sensor means operatively associated with said assembly for detecting the presence of a user; and

,

i) electronic control means operatively associated with said dispensing means, said first and second means, and said sensor means for electronically causing soap and water to be selectively supplied to said faucet and for thereafter causing a length of toweling to be dispensed.

18. The wash station of claim 17, wherein:

a) counter means being operatively associated with said control means so that usage thereof may be monitored.

19. The wash station of claim 17, wherein:

a) said second means including a pump for supplying a predetermined quantity of soap to said faucet.

20. The wash station of claim 19, wherein said pump includes:

a) a cylindrical shell comprised of a substantially rigid material, said shell being closed at the ends thereof and each end having an opening therein providing an inlet and an outlet and an aperture being disposed in said shell intermediate said inlet and outlet;

b) a resilient bladder disposed within said shell, said bladder having a central passage aligned with said inlet and said outlet and an annular chamber in communication with said aperture; and

,

c) means interconnecting said aperture with said source for causing water to be selectively supplied to said chamber so that said chamber expands and thereby causes said central passage to be collapsed and soap is thereby caused to be forced from said central passage to said faucet.

21. The wash station of claim 20, wherein:

a) a resilient conduit being positioned within and extending from said central passage for providing a continuous flow path for the soap, said conduit being removable from said central passage.

22. The wash station of claim 17, wherein:
