Description

Quick mode control method of the refrigerator.

The present invention relates to a method for controlling a rapid mode of a refrigerator, and more particularly, to a method for controlling a rapid mode of a refrigerator to improve the performance of a refrigerator by performing a fixed mode for a predetermined time after completion of defrosting when setting a rapid mode of the refrigerator. .

In general, the conditions to be considered during the defrost cycle are: cumulative compressor operation time (6, 8, 10 hours), compressor operation rate (compressor operation cumulative operation time 2 hours), compressor operation time + compressor stop Time (more than 60 hours), cumulative door open time, outside temperature, errors of various sensors (D-sensor, F-sensor, outside temperature sensor) and door switch error.

The inrush condition to the defrost mode is a door that does not satisfy the above defrost inrush condition when the compressor operation rate is 2% or more when the defrost inrush condition is satisfied at 6, 8 and 10 hours of operation time of the compressor. When the open cumulative time is 10 minutes or more, when the outside temperature is 35 degrees or more and the compressor operation cumulative time is 6 hours or more, various types of errors occur and the defrost is started.

Then, if the operating time of the compressor + the stop time of the compressor is 60 hours or more, it immediately enters the defrost mode.

In addition, if the cumulative operation time of the compressor is 10 hours or more, the defrost mode is unconditionally entered. In the usual case, when the cumulative time of the compressor reaches 10 hours, the compressor is defrosted.

On the other hand, the defrost mode goes through the process of precooling, heater defrosting, rest period, fan delay, etc., Pre-COOL step is the step that the compressor, F-Fan is on for 50 minutes and time (50 minutes) Even if this time has not elapsed, the flick function is turned off if the temperature detected by the F-sensor is below -27 ° C.

In the defrosting step of the heater (HTR), the heater is turned off when the temperature detected by the D-sensor is 10 ° C. or more, and the limit time is 80 minutes. When the D-sensor is an error, the heater is driven on for 40 minutes.

The pause period is 4 minutes, and the compressor, F-fan and R-fan are all off, the fan delay time is 5 minutes and only the compressor is turned on.

During normal operation of the refrigerator, the temperature detected by the defrost detection sensor (D-sensor) of the refrigerator varies in response to the operation rates of the compressor, the F-fan, and the R-fan of the refrigerator.

However, when the rapid mode is set during defrosting of the refrigerator, the rapid mode is performed only for the remaining time of the ramping time performed in the above-described precooling step, which causes a problem in that cooling performance is deteriorated.

The present invention has been made to solve the above problems, and provides a quick mode control method of the refrigerator to improve the performance of the refrigerator by performing the fixed mode for a predetermined time after the completion of the defrosting when setting the rapid mode of the refrigerator. Its purpose is to.

Next, the operation of the method for controlling the rapid mode of the refrigerator according to the preferred embodiment of the present invention including the above-described component will be described in detail with reference to the flowchart of FIG. 2.

First, the microcomputer determines whether the refrigerator is in defrost condition (step 200).

In case of defrost, the pre-cool step is performed (step 210). The compressor and F-fan are driven on for 50 minutes and the F-sensor is detected even if the time (50 minutes) has not elapsed. If the temperature is below -27 ° C, the fleek function is turned off.

If the rapid mode is set during the precooling (step 220), the operation is performed in the rapid mode (step 230). When the rapid completion is completed (step 240), the precooling step is performed for the remaining time (step 250).

In the defrosting stage of the heater (HTR), the heater is turned off when the temperature detected by the D-sensor is 10 ° C. or higher, and the limit time is 80 minutes. When the D-sensor is an error, the heater is driven on for 40 minutes. .

A pause phase is then performed, with the pause period being 4 minutes and the compressor, F-fan and R-fan all off, the fan delay time being 5 minutes and only the compressor running on (step 260).

At this time, if it is determined that the rapid mode is set (step 270), if it is not set, it is determined whether defrost is completed (step 280), and normal operation is completed (step 320). .

When the rapid mode is set, it is determined whether the defrost has been completed (step 290). If the defrost is not completed, the defrost is continuously performed, and when it is completed, the entire speed of the predetermined rapid mode progression is driven in the rapid mode.

Subsequently, it is determined whether the high speed operation is completed, and normal operation is performed upon completion.

In the rapid mode control method of the refrigerator according to the present invention, the performance of the refrigerator may be improved by performing the ramp mode for a predetermined time period after the completion of defrosting when the rapid mode of the refrigerator is set.
