TEMPERATURE CONTROL APPARATUS OF WORKING MACHINE
First Claim
1. A temperature control apparatus of a working machine including ventilating means for replacing internal air in the working area with external air surrounding the working machine between the working area inside the working machine and the exterior of the working machine, comprising:
- a working area temperature sensor that detects a temperature of the working area;
an external air temperature sensor that detects an external temperature surrounding the working machine;
a ventilating means drive unit that drives the ventilating means; and
a ventilating means control unit that compares the temperature in the working area, which is detected with the processing area temperature sensor, the external temperature surrounding the working machine, which is detected with the external air temperature sensor, and a pre-set target temperature in the working area and, in accordance with a result of the comparison, outputs a signal for driving or stopping the ventilating means to the ventilating means drive unit when the working machine is not being operated.

Abstract
Provided is a temperature control apparatus of a working machine that is inexpensive, energy-saving and capable of eliminating the temperature difference between a temperature in a room in which the working machine is installed and a temperature of a working area.
Whether an average value T5 is higher or lower than both a target temperature T1 in the working area and an air temperature T2 in the room is checked and, if the result is YES, the routine proceeds to step S8 for driving a cylinder 175 to open a cover 173 and open a opening for working 172. Then, internal air in a working area A is replaced with external air surrounding a numerically controlled lathe 1 and the temperature in the working area approaches the air temperature T2 in the room. If the result is NO, the cylinder 175 is driven to close the cover 173 and close the opening for working 172. Then, replacement of the internal air in the working area A with the external air surrounding the numerically controlled lathe 1 is ended and the operation of the temperature control apparatus is ended.
