Defrosting device for a cooling surface

摘要

A defrosting device for a cooling surface 1 has a switch device 3 for the control of a refrigeration unit and a drain system 5 for the defrosted medium. In order to be able to determine the end of the defrosting process, a sensor 7 influenced by the defrosted medium is provided which controls the switch device 3 such that the cooling unit remains switched off as long as defrosting medium flows out. <IMAGE>
