Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a refrigerator control device.

[0002]

2. Description of the Related Art As a conventional refrigerator, one shown in FIGS. 5 and 6 has been proposed (Japanese Utility Model Laid-Open No. 63-162283). In FIG. 5, 1 is a compressor, 2 is a cooler, 3 is a fan, 4 is a refrigerating compartment, 6 is a damper for controlling cold air to the refrigerating compartment 4, 9 is a freezing compartment, and 8 is a temperature of the freezing compartment 9. An F thermistor 10 is an R thermistor that detects the temperature of the refrigerator compartment 4.

Further, in FIG. 6, a power source 17 for electric parts is provided.
There are switches 18, 19 and 20 as means for switching on and off, which are a compressor 1, a fan 3 and a damper 6, respectively.
This is a contact that turns ON / OFF. The microcomputer 27 determines which of these is to be energized.

The thermistors 9 and 10 are input to the microcomputer 27. Here, 29 and 30 are thermistors and voltage dividing resistors for dividing the voltage. The damper 6 was operated by the R thermistor 10 regardless of whether the door was opened or closed.

[0005]

Since the conventional refrigerator performs the damper operation regardless of the state of the door of the refrigerator as described above, when the damper operation is performed when the door is opened, the gear generation noise of the damper, the motor, and the like. There is a problem that the user may notice the vibration sound of the.

The present invention has been made to solve the above problems, and an object of the present invention is to obtain a control device for a refrigerator / freezer which performs a damper operation after a certain period of time has elapsed when the door is opened.

[0007]

The control device for a refrigerator according to the present invention is provided with means for delaying the operation of the damper for a certain period of time when the door is open.

[0008]

Since the control device for the refrigerator / freezer according to the present invention operates the damper after the elapse of a certain time when the door is opened,
Users can use the refrigerator without worrying about the sound of damper gears and the vibration of motors.

【Example】

Example 1. An embodiment of the present invention will be described below with reference to FIGS.
Will be explained. FIG. 1 is an overall configuration diagram of an embodiment of a control device for a refrigerator according to the present invention. 1 is a compressor for compressing and circulating a refrigerant, 2 is a cooler for evaporating the refrigerant, 3
Is a fan for circulating the cool air cooled by the cooler 2, 4 is a refrigerating compartment, 5 is a refrigerating compartment air passage for guiding a part of the cool air to the refrigerating compartment 4, and 6 is a refrigerating compartment for opening and closing the air passage 5. A damper for controlling the cold air to 4; a defrosting heater for defrosting the cooler 2; a defrosting room; 8 an F thermistor for detecting the temperature; 10 an R for detecting the temperature of the refrigerating room 4.
The thermistor, 11 is a door detector that detects opening and closing of the door, 1
3 is a defrosting thermistor that detects the temperature of the cooler 2 in order to finish the defrosting, 14 is a control board that controls the entire refrigerator, and the control board 14 comprises a control means 15 and a control method determination means 16.

Next, the contents of the control means 15 will be described with reference to FIG. In FIG. 2, there are switches 18, 19 and 20 as means for turning on / off the power supply 17 of the electric parts, which are contacts for turning on / off the compressor 1, the fan 3, the damper 6 and the defrosting heater 7, respectively. The contacts are driven by coils 21, 22, and 23, respectively, and the coils 21, 22, and 23 are energized by drive circuits 24 and 2, respectively.
5, 26 are energized, and which one is energized is determined by the microcomputer 27.

The inputs of the microcomputer 27 are the thermistors 9, 10, 12, 13 and the door detector 11. Here, 28 to 31 are voltage divider resistors for dividing the voltage with the thermistor.

Next, the structure of the control method determining means 16 will be described with reference to FIG. It is input by the door state detection means 40 that detects the door open / closed state. Timer 41 from the time the door opens
After a certain period of time has elapsed, the damper operation determining means 42 determines the final damper control.

Next, the contents of the control method determining means 16 will be described with reference to FIG. First, step 50
Detect the condition of the door. When the door is closed, the damper 6 is sequentially opened and closed according to the damper opening / closing conditions. Next, when the door is opened,
If it is within t hours in step 51, the damper is not operated regardless of the opening / closing condition of the damper 6. Then t
After the lapse of time, in step 52, the damper 6 is operated according to the opening / closing condition of the damper.

[0014]

As described above, according to the present invention, in the refrigerator having the detecting means for detecting the opening and closing of the door and the damper for adjusting the temperature inside the refrigerator, the damper operation when the door is opened is delayed for a certain period of time. By providing the means to operate,
The user can use the refrigerator without worrying about the noise generated by the gears of the damper and the vibration noise of the motor.
