Abstract

A disposal apparatus for use with a wash station and a towel dispenser includes a liquid source and a waste disposal unit arranged in fluid communication with the liquid source that (i) collects liquid from the liquid source and receives a spent towel dispensed from the towel dispenser, (ii) disintegrates the spent towel and generates a fluid vortex of liquid and disintegrated spent towel, and (iii) exhausts the fluid vortex. A hand washing and drying apparatus comprises a washing and drying chamber including at least one access port providing access for inserting at least one hand to be washed, a wash liquid dispenser in fluid communication with the interior of the washing and drying chamber for dispensing wash liquid within the washing and drying chamber, a blow dryer in fluid communication with the interior of the washing and drying chamber for providing a directed supply of drying air within the washing and drying chamber, a towel dispenser in communication with the interior of the washing and drying chamber for dispensing a towel, e.g., a disposable paper towel, within the chamber, and a waste disposal unit for disintegrating a spent towel dispensed from the towel dispenser and exhausting disintegrated waste through a drain. The apparatus further may include a control device for controlling the operation of the apparatus.

Claims

1. A disposal apparatus for use with a wash station and a towel dispenser, the disposal apparatus comprising:

a liquid source; and

a waste disposal unit having a base portion and a chamber portion above the base portion, where said waste disposal unit is arranged in fluid communication with the liquid source and (i) collects liquid from said liquid source and receives a spent towel dispensed from said towel dispenser, (ii) disintegrates the spent towel and generates a fluid vortex of liquid and disintegrated spent towel in the chamber portion above the base portion, and (iii) exhausts the fluid vortex from an upper portion of the chamber portion.

2. The disposal apparatus of claim 1, wherein the waste disposal unit comprises a blender.

3. The disposal apparatus of claim 2, wherein said blender exhausts the fluid vortex by centrifugal effect.

4. The disposal apparatus of claim 3, wherein said blender comprises a base, a cup and a rotor that disintegrates the spent towel and generates the fluid vortex of disintegrated towel and liquid in said cup.

5. The disposal apparatus of claim 4, wherein said blender exhausts the fluid vortex through an opening in a side of the cup.

6. The disposal apparatus of claim 1, wherein the waste disposal unit exhausts the fluid vortex by centrifugal effect.

7. The disposal apparatus of claim 6, wherein the fluid vortex has an upper portion and a lower portion, and the waste disposal unit exhausts the fluid vortex at the upper portion.

8. The disposal apparatus of claim 1, wherein the wash station is integral with the disposal apparatus, and is provided in fluid communication with the disposal apparatus.

9. The disposal apparatus of claim 8, wherein the wash station comprises a washing and drying chamber, and the towel dispenser is arranged in communication with the interior of the washing and drying chamber.

10. The disposal apparatus of claim 1, wherein said waste disposal unit exhausts the fluid vortex into a standard plumbing line.

11. A disposal apparatus for use with a wash station and a towel dispenser, the disposal apparatus comprising:

a liquid source; and

a waste disposal unit arranged in fluid communication with the liquid source that (i) collects liquid from said liquid source and receives a spent towel dispensed from said towel dispenser, (ii) disintegrates the spent towel and generates a fluid vortex of liquid and disintegrated spent towel, and (iii) exhausts the fluid vortex,

wherein the wash station is integral with the disposal apparatus, and is provided in fluid communication with the disposal apparatus, and

wherein the wash station comprises a washing and drying chamber, and the towel dispenser is arranged in communication with the interior of the washing and drying chamber.
