DIAL-MODE TEMPERATURE CONTROLLER THAT FACILITATES CHANGING OF TEMPERATURE RANGE
First Claim
Patent Images
1. A dial type temperature controller easily changing a temperature range, comprising:
- a selector that is electrically connected to the front of a PCB module with various electronic circuits for temperature control and sets different temperature ranges by turning step by step;
a selector handle that is combined with the selector to turn the selector and has a protrusion on one side to discriminate the temperature ranges;
a case inside which accommodates the PCB module and the selector and which is combined with the selector handles through one side;
an indication panel that has protrusion insertion holes at different positions corresponding to the protrusion, for each temperature range set by turning the selector handle, and is marked with temperature graduations corresponding to the temperature ranges selected by the selector;
a dial that is easily and detachably inserted to be fitted on a temperature control switch that is turned in electric connection with the front of the PCB module to set temperature within a temperature range selected by the selector; and
a microcomputer that is programmed to convert a temperature signal corresponding to the amount of turn of the dial into a temperature signal calculated in proportion to a temperature range selected by the selector and recognize the converted signal.
