Abstract

A drying apparatus includes an outer case, a portion of the outer case defining a cavity in which articles can be dried and an outlet disposed at the lower end of the cavity. A removable liquid treatment module is arranged downstream of the outlet and within the outer case, the liquid treatment module including a liquid dispersal unit. By providing a liquid treatment module that is removable, the liquid treatment module can be easily and quickly replaced by an unskilled user without undue burden. The invention is particularly suitable for use in a hand dryer.

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 the lower end of the cavity,
