Abstract

A drying apparatus has a casing, a cavity formed in the casing for receiving an object, a fan located in the casing and creating an airflow, and at least one slot-like opening communicating with the fan and arranged in the casing so as to direct an airflow transversely across the cavity. The slot-like opening is formed between opposing walls so that one of the walls terminates substantially flush with the casing and the other wall protrudes beyond the casing. The slot-like opening may be formed between an upper wall and a lower wall, the lower wall may terminate substantially flush with the casing and the upper wall protrudes beyond the casing, reducing the effect of the air causing the user'"'"'s hands to be pulled or sucked towards the slot-like openings but eliminating any protrusion of the walls of the slot-like opening on one side.

Claims

1. A drying apparatus, comprising a casing, a cavity formed in the casing for receiving an object, a fan located in the casing and creating an airflow, and at least one slot-like opening communicating with the fan and arranged in the casing to direct an airflow transversely across the cavity, the slot-like opening being formed between opposing walls, wherein one of the walls terminates substantially flush with the casing and the other wall protrudes beyond the casing.

2. The drying apparatus as claimed in claim 1, wherein the slot-like opening is formed between an upper wall and a lower wall.

3. The drying apparatus as claimed in claim 2, wherein the lower wall terminates substantially flush with the casing and the upper wall protrudes beyond the casing.

4. The drying apparatus as claimed in claim 3, wherein the upper wall protrudes beyond the casing to a distance of about 5 mm.

5. The drying apparatus as claimed in claim 1 or 2, wherein the velocity of the airflow emitted through the slot-like opening is at least 80 m/s.

6. The drying apparatus as claimed in claim 5, wherein the velocity of the airflow emitted through the slot-like opening is at least 100 m/s.

7. The drying apparatus as claimed in claim 1 or 2, wherein the pressure of the airflow emitted through the slot-like opening is at least 15 kPa.

8. The drying apparatus as claimed in claim 7, wherein the pressure of the airflow emitted through the slot-like opening is at least 20 kPa.

9. The drying apparatus as claimed in claim 1 or 2, wherein two opposed slot-like openings are provided, one slot-like opening being provided on each of front and rear walls of the cavity.

10. The drying apparatus as claimed in claim 1 or 2, wherein the drying apparatus is a hand dryer.
