Dial-mode temperature controller that facilitates changing of temperature range

摘要

The present invention relates to a dial type temperature controller easily changing a temperature range that is provided with a selector for changing temperature ranges and indication panels for selected corresponding ranges and allows a user to easily change the temperature range without an error, when changing the temperature range and the indication panel, and also stops control output with a dial of the temperature.

主权项

1. A dial type temperature controller, comprising:
a selector that is electrically connected to a 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 handle through one side; a plurality of indication panels, each having a protrusion insertion hole at a different position corresponding to the protrusion, for each temperature range set by turning the selector handle, and each is marked with temperature graduations corresponding to the temperature ranges selected by the selector; a dial that is 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 an amount of turn of the dial into a temperature signal calculated in proportion to a temperature range selected by the selector and that recognizes the converted signal.
