Fig. 4 is the circuit diagram for indicating the example of abnormal temperature detection circuit of embodiment 1.
Abnormal temperature detection circuit 29 for example has the comparator IC (Integrated that output is open collector construction
Circuit, integrated circuit).
Comparing section 30 has the 1st comparator 32 and the 2nd comparator 33.A point is that the reversion of the 1st comparator 32 inputs
(-).B point is the non-inverting input (+) of the 1st comparator 32.C point is the output of the 1st comparator 32.By resistance R714 and temperature
The branch pressure voltage that degree sensor 14 generates is input into a point.The voltage of a point because of the temperature of temperature sensor 14 according to changing
Resistance value and change.It is generated by resistance R716, resistance R717, resistance R718, resistance R719, resistance R720 and resistance R721
Branch pressure voltage is input into b point.
In the case where compressor temperature is lower than stopping temperature, the resistance value of temperature sensor 14 is big.At this point, as reversion
The voltage ratio for inputting a point of (-) is high as the voltage of the b point of non-inverting input (+).As a result, as the defeated of the 1st comparator 32

It connects in succession.
Then, illustrate the movement of the dehumidifier 1 of embodiment 1.
When the reset input of microcomputer 21 is low level, the program of microcomputer 21 is halted state.At this point,
The pin P1 and pin P2 of microcomputer 21 become input pattern from output mode respectively.As a result, from microcomputer 21

When wet machine 1 stops, in the case that the operation connected during 0.1 second to 0.3 second or so is continuously detected, miniature calculating
Machine 21 is judged to having accepted the operation of primary connection.On the other hand, when dehumidifier 1 operates, when on 0.1 second to a 0.3 second left side
In the case that the operation turned off during the right side is continuously detected, microcomputer 21 is judged to having accepted the behaviour of primary shutdown
Make.
In the high feelings of the value that operating switches 20 are humidity of the measured value than predetermining connected and based on humidity sensor 7
Under condition, dehumidifier 1 starts the movement of dehumidifying.Dehumidifier 1 makes refrigerant in the pre-determined time from the movement for starting dehumidifying
Stablize.Dehumidifier 1 starts the movement of compressor 6a after stablizing refrigerant.The time example that dehumidifier 1 keeps refrigerant stable
For example 3 minutes.The time that dehumidifier 1 keeps refrigerant stable stops timer measurement by starting.Starting stop timer for example by

Type computer 21 is after being stopped timer by starting and measuring 3 minutes, as the signal for acting compressor 6a by high electricity
Flat signal is output to pin P2.
When the output of the pin P2 of microcomputer 21 is high level, signal is input to transistor Q1's via resistance R2
Base stage.At this point, transistor Q1 becomes on-state, so that the operation coil of relay X1 is energized.Relay X1 makes electric power
The junction closure of the circuit of compressor 6a is supplied to from power supply 27.Compressor 6a is operated as a result, with constant speed.
The output voltage of the current transformer of current sensor 15 is applied to the both ends of resistance R1.Diode D1 only makes defeated
The anode of voltage passes through out.Capacitor C1 makes the output voltage smoothing for having passed through diode D1.The output voltage for being smoothed

When the compressor temperature detected by temperature sensor 14 is more than to stop temperature, abnormal temperature detection circuit 29 makes
The signal for being output to output terminal is inverted to low level.No matter the output state of the pin P2 of microcomputer 21 as a result,
The voltage for being applied to the contact of the base stage of resistance R2 and transistor Q1 is all low level.At this point, transistor Q1 becomes an OFF state,
To the operation coil no power of relay X1.Relay X1 makes to connect electric power from the circuit that power supply 27 is supplied to compressor 6a
Point open circuit.It is cut off as a result, from the signal that microcomputer 21 is output to driven compressor portion 23, so that compressor 6a stops.
