Title:
OPERATION PIECE AND REFRIGERATOR THERMOSTAT USING SAME
Document Type and Number:
WIPO Patent Application WO/2016/117752
Kind Code:
A1
Abstract:
The present invention relates to a refrigerator thermostat and, particularly, to: an operation piece pushing the hemisphere of a push bar while reducing friction with respect to the hemisphere and encompassing the hemisphere, when the operation piece rotates, such that friction surfaces of the push bar and the operation piece are not deformed even with the continuous use thereof, thereby preventing a malfunction; and a refrigerator thermostat using the same. The operation piece (1000) of a refrigerator thermostat, of the present invention, is characterized in that: the operation piece (1500) transmits force to a push bar (1400) so as to connect or short a switch unit (1600) connected to a power terminal (1700), while rotating by the expansion of a bellows (1120), which is connected to one end of a temperature sensing unit (1110) connected to one side of a main body (1100) and operates so as to be expanded according to a temperature change, wherein the operation piece (1500) has a hemispheric groove (1510) formed at a place coming into contact with the hemisphere (1410) of the push bar (1400) so as to accommodate the hemisphere of the push bar.
