Heat generator for refrigerator, has diode connected in series with relay to lower voltage applied to lamp, by half-wave rectification

摘要

#CMT# #/CMT# A control unit outputs control signal for driving lamp and for low temperature compensation, based on door open/close and external temperature signals. The relay and switch connected in series with lamp unit, are tuned ON/OFF based on control signal. A diode connected in series with relay, lowers the voltage applied to lamp, by half-wave rectification. #CMT# : #/CMT# An independent claim is also included for control method of heat generator. #CMT#USE : #/CMT# For generating heat in direct cooling type refrigerator. #CMT#ADVANTAGE : #/CMT# Enables reducing the cost of the refrigerator by using a cheap diode instead of using expensive capacitor. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The figure shows a schematic view of the direct cooling type refrigerator.
