The present invention relates to a control method for driving a high lamp of a refrigerator. In particular, the lamp of a refrigerator for detecting a heat generated by a lamp of a refrigerator that is turned on due to an error of a user is automatically turned off when a predetermined heating temperature and time are reached. It relates to a drive control method.

In general, refrigerators used in homes and businesses are equipped with a lamp to illuminate the lamp when the door is opened, but at this time, the lamp may be turned on for a long time due to an artificial condition or defective parts of the user. Due to the heat generated in the lamp, the temperature inside the lamp is increased to damage the stored food, and even the fire may be caused.

Accordingly, an object of the present invention is to attach a temperature sensor to detect the temperature and the heat of the lamp inside the refrigerator of the refrigerator to detect the lighting state of the lamp by the heat detected by the temperature sensor, the lighting of the lamp may be caused by artificial or defective In order to solve the various problems, the present invention is to detect the temperature inside the high temperature and the inside of the high temperature and the internal temperature determination step of determining whether the detected internal temperature is above a predetermined temperature, and the internal temperature According to the temperature determination step detected in the temperature judging step, the door open state determination, time count and a predetermined time of high light control step is performed.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

In the high temperature determination step 21 for determining whether the detected temperature is higher than a predetermined temperature (80 ° C.) and the time for clearing the time count if the high temperature in the high temperature determination step 21 is not higher than a predetermined temperature. In the counting clearing step 22 and the high temperature proof step 21, the door opening determining step 23 determines whether the door is open when the internal temperature is higher than a predetermined temperature, and the door in the door opening determining step 23. Is a first time count step 24 for counting time if is open, a time determination step 25 for determining whether or not a predetermined time (20 minutes) of the time counted in the first time count step 24 is exceeded; , Above If the predetermined time has not elapsed in the determination step 25, the time counting step 22 is performed and a general internal temperature detection function is performed, and when the counted time is longer than a predetermined time, the counted time is performed. A time count clearing step 26 for clearing the lamp, an internal lamp turning off step 27 for turning off the lamp, and a time count step for counting the lighting time of the lamp inside if the door is not opened in the door opening determination step 23; ), A predetermined time judging step 29 for determining whether the time counted in the time counting step 28 is a predetermined time (1 minute) or more, and a time counted in the predetermined time judging step 30 is predetermined. If the time is not more than the time counting step 22 to perform a general internal temperature detection function, and the counted time is more than a predetermined time And a time clearing step 31 for clearing the counted time, and a high light turning off step 31 for turning off the high light.

Referring to the effects of the present invention configured as described above are as follows.

First, in the state where the refrigerator is running, the microcomputer (la) goes to the high temperature sensing step (20) and senses the temperature in the refrigerator through the temperature detecting unit (C) of FIG. 1, and then the microcomputer (la) determines the high temperature inside. Going to step 21, it is determined whether the inside temperature detected in the inside temperature detecting step 20 is equal to or greater than a predetermined temperature (80 ° C) which is a preset temperature, and when the inside temperature is determined to be above the predetermined temperature. In the micom (d), go to the time count clear step (22) to clear the time and perform the internal temperature detection function of the refrigerator, while the microcomputer (d) according to the function and operation state inputted from the input unit (b) of FIG. The control drive and outputs the controlled state to the output driver (e) to drive the refrigerator normally.

However, if the temperature determined in the high temperature determination step 21 is above a predetermined temperature, the microcomputer (d) goes to the door open determination step 23 to determine whether the door is open, and if the door is open, the micom ( D) go to the time count step 24 to count the time that the door is opened, and then go to the time judgment step 25 and the time counted in the time count step 24 is a predetermined time 20 minutes. At this time, if the time that the door is open is not longer than the predetermined time, the microcomputer d goes to the time count clear step 22 to clear the counted time and the temperature at the microcomputer d. It will drive the refrigerator while detecting.

However, when the door opening count time is more than the predetermined time in the time counting step 24, the microcomputer (la) goes to the time counting clearing step 26 to clear the time counted for the predetermined time or more, and the micom ( D) to turn off the interior light by controlling the output driver (e).

On the other hand, if the door is not opened in the door opening determination step 23, the microcomputer (d) goes to the time counting step 28 and counts the time when the interior lamp is turned on while the door is closed, and determines the predetermined time determination step 29 In step 2), it is determined whether the time counted in the time count step 28 is equal to or greater than a predetermined time (1 minute), and if the counted time is not equal to or greater than the predetermined time, the microcomputer d determines the time count. Go to the clearing step 22, clear the time and perform the internal temperature detection function of the refrigerator according to the function and operation state inputted from the input unit (b) of FIG. 1, the microcomputer (D) drives the control and outputs the controlled state. Output to the drive unit (e) to drive the refrigerator normally.

However, if the time counted in the predetermined time determination step 29 does not exceed the predetermined time, the microcomputer (d) goes to the predetermined time determination step 30 to clear the counted time and to control the output driver (e). To turn off the lamp.

As described above, the present invention is attached to a temperature sensor that detects the temperature of the inside of the refrigerator and the heat of the interior lamp to detect the lighting state of the interior lamp by the heat detected by the temperature sensor, the lighting of the interior lamp due to artificial or defective It will provide an effect that can solve all the problems that may be caused.
