Abstract

A drying apparatus includes an outer case, a portion of the outer case defining a cavity, an outlet disposed at a lower end of the cavity and a liquid dispersion unit, the liquid dispersion unit comprising a collector downstream of the outlet, a liquid evaporation unit in communication with the collector and an airflow generator for exhausting evaporated liquid from the collector to the exterior of the outer case. The liquid evaporation unit includes a high frequency agitator, such as a piezo-electric device. The piezo-electric device, when in use, agitates the surface of the water, and the water can be evaporated at a low energy cost. The waste liquid is therefore removed from the drying apparatus more hygienically and economically than known prior art arrangements.

Claims

1. A drying apparatus comprising:

an outer case, a portion of the outer case defining a cavity in which articles can be dried,

an outlet disposed at a lower end of the cavity,

a liquid dispersion unit comprising a collector downstream of the outlet and a liquid evaporation unit in communication with the collector and comprising a high frequency agitator.

2. The drying apparatus according to claim 1, further comprising an airflow generator for exhausting evaporated liquid from the collector to the exterior of the outer case.

3. The drying apparatus according to claim 1 or 2, wherein the liquid evaporation unit is attached to the collector.

4. The drying apparatus according to claim 1 or 2, wherein the high frequency agitator is electro-mechanical.

5. The drying apparatus according to claim 4, wherein the high frequency agitator is a piezoelectric device.

6. The drying apparatus according to claim 4, wherein the high frequency agitator is an ultrasonic generator.

7. The drying apparatus according to claim 1 or 2, further comprising a motor unit capable of performing a drying action on the articles to be dried.

8. The drying apparatus according to claim 1 or 2, wherein the airflow generator comprises a fan in communication with the collector.

9. The drying apparatus according to claim 8, wherein the fan is part of the motor unit.

10. The drying apparatus according to claim 1 or 2, wherein a drain channel is located at the lower end of the cavity, and the outlet is located in the drain channel.

11. The drying apparatus according to claim 1 or 2, wherein the drying apparatus is a hand dryer and the cavity is dimensioned to receive a user'"'"'s hands.

12. The drying apparatus according to claim 1 or 2, wherein the drying apparatus is a laundry dryer and the cavity is dimensioned to receive textiles.
