Abstract

A drying apparatus having 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 is formed between opposing walls which approach one another at an angle of between 10° and 20°. In another aspect, two slot-like openings are provided ducting providing communication between the fan and the slot-like openings has a first cross-section in the vicinity of the fan whose dimensions are similar in all directions and a slot-like cross-section in the vicinity of the openings, the transition between the said cross-sections being gradual and smooth.

Claims

exact text as granted — not AI-modified
1 . A drying apparatus, comprising a casing, a cavity formed in the casing for receiving an object, a fan located in the casing and capable of 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,
 wherein the slot-like opening is formed between opposing walls which approach one another at an angle of between 10° and 20°.   
   
   
       2 . The drying apparatus as claimed in  claim 1 , wherein the opposing walls approach one another at an angle of about 14°. 
   
   
       3 . A drying apparatus having comprising a casing, a cavity formed in the casing for receiving an object, a fan located in the casing and creating an airflow, and two opposing slot-like openings communicating with the fan via ducting and arranged in the casing to direct an airflow transversely across the cavity,
 wherein the ducting has a first cross-section in the vicinity of the fan whose dimensions are similar in all directions and a slot-like cross-section in the vicinity of the openings, a transition between the said cross-sections being gradual and smooth.   
   
   
       4 . The drying apparatus as claimed in  claim 3 , wherein the total cross-sectional area of the ducting is substantially constant between the fan and a point immediately upstream of the slot-like openings. 
   
   
       5 . The drying apparatus as claimed in  claim 3  or  4 , wherein the ducting is divided into two separate airflow paths at a point downstream of the fan. 
   
   
       6 . The drying apparatus as claimed in  claim 1  or  3 , wherein the width of the or each slot-like opening is no more than 0.5 mm. 
   
   
       7 . The drying apparatus as claimed in  claim 1  or  3 , wherein the fan is adapted to cause an airflow to be emitted through the or each slot-like opening at a velocity of at least 80 m/s. 
   
   
       8 . The drying apparatus as claimed in  claim 7 , wherein the fan is adapted to cause an airflow to be emitted through the slot-like opening at a velocity of at least 100 m/s. 
   
   
       9 . The drying apparatus as claimed in  claim 1  or  3 , wherein the fan is adapted to cause an airflow to be emitted through the or each slot-like opening at a pressure of at least 8 kPa. 
   
   
       10 . The drying apparatus as claimed in  claim 9 , wherein the fan is adapted to cause an airflow to be emitted through the or each slot-like opening at a pressure of at least 12 kPa. 
   
   
       11 . The drying apparatus as claimed in  claim 1  or  3 , wherein the drying apparatus is a hand dryer. 
   
   
       12 . (canceled)
