Description

TECHNOD FOR CONTROLLING A DRIVING MODE IN A KIMCHI REFRIGERATOR}

The present invention relates to a method of driving a kimchi refrigerator, and more particularly, to a method of driving a freezing mode of a kimchi refrigerator.

Kimchi refrigerator is a four-season household appliance developed to provide consumers with better taste by fermenting fermented foods such as kimchi, and the principle was conceived at the time and temperature of kimchi ripening in the ground.

In other words, kimchi should be aged at low temperature at 0 ~ 7 ℃ and stored at around 0 ℃ in order to taste properly. Kimchi refrigerator is designed to automatically adjust to the kimchi ripening time and temperature of the kimchi poison under the ground.

Kimchi refrigerators that are currently available to consumers generally have such aging or storage functions in parallel, and are provided with storage compartments (typically two storage compartments) for accommodating these functions.

That is, in the ripening mode of the kimchi refrigerator, the kimchi that is matured according to the tastes of consumers by stopping the operation of the compressor in the kimchi refrigerator and driving the heater at a constant temperature to maintain the storage compartment, for example, the lower storage compartment at a temperature of 0-7 ° C. In the storage mode, the compressor is driven for a predetermined time to maintain the storage compartment, for example, the upper storage compartment at a temperature of 0 ℃ to provide fresh kimchi to the consumer to the consumer.

However, as described above, the kimchi refrigerator has a limitation in function, that is, only the ripening or storage mode can be performed. That is, in order to store kimchi for a long time, for example, several months, the storage mode described above is limited.

In addition, when the amount of kimchi is small, the storage function is not required, and the inefficient aspect of not utilizing 100% of the function of the kimchi refrigerator has also emerged.

Applicant has focused on overcoming these limitations and drawbacks by setting a mode that can lower the temperature of one of the storage compartments above, that is, selectively controlling the operation of the compressor required for the storage mode. .

Accordingly, the present invention has been made in view of the above-described concept, to provide a freezing mode driving method of the kimchi refrigerator to drive in the refrigeration mode by controlling the drive of the compressor according to the storage room temperature of the kimchi refrigerator driving in the ripening mode or storage mode. The purpose is.

That is, the present invention is divided into the first and second storage compartment, in the freezing mode driving method of the kimchi refrigerator driving in the ripening mode or storage mode, determining whether a key signal for driving the freezing mode is driven in the freezing mode A first step of determining whether the compressor is on when a key signal for the is applied; If the compressor is on, a second step of measuring a temperature in the first reservoir; A third step of turning off the compressor if the measured temperature in the first storage compartment is less than or equal to the first set temperature; A fourth step of measuring a temperature in the first storage compartment when the compressor is turned off as a result of the determination in the first step; When the measured temperature in the first storage room is equal to or higher than the second set temperature, it provides a freezing mode driving method of the kimchi refrigerator characterized in that the fifth step of turning on the compressor.

As shown, the key input unit 100 is composed of key input means required for selecting various functions of the kimchi refrigerator, for example, ripening, storage, and freezing mode, according to the user's key input operation, the micom 102 )

The compressor 104 is a type of pump that circulates a refrigerant, and compresses and delivers a gas refrigerant at a high temperature and high pressure to maintain a low pressure so that the liquefied refrigerant of the evaporator is easily evaporated. Under the control of the microcomputer 102, it is driven until a certain temperature is reached.

The solenoid valves 106 and 108 are provided in the A and B rooms of the Kimchi refrigerator, respectively, and are controlled on / off under the control of the microcomputer 102 to regulate the flow of the refrigerant.

The heater driving units 110 and 112 are provided in the A and B chambers of the Kimchi refrigerator, respectively, and are driven until the predetermined temperature is reached in the aging mode described later under the control of the microcomputer 102.

The temperature sensors 114 and 116 are provided in the A and B rooms of the Kimchi refrigerator, respectively, and provide data to the microcomputer 102 by measuring the temperature of the A and B rooms.

The memory unit 118 may be configured of, for example, EEPROM (Electrically Erasable and Programmable Read Only Memory), and temperature data necessary for performing various modes are recorded. These data are then read by the microcomputer 102.

Hereinafter, the above-described configuration will be described in detail with reference to the flowchart of FIG. 2 attached to the freezing mode driving process of the kimchi refrigerator performed by the microcomputer 102 according to the present invention.

First, in order to help the understanding of the process, after describing the kimchi refrigerator driving process in the ripening mode and storage mode, the freezing mode driving process according to the present invention will be described.

First, when a predetermined key signal is applied to the microcomputer 102 from the key input unit 100, the microcomputer 102 proceeds to step S200 to determine whether the applied key signal is a key signal for performing the aging mode, and performing the storage mode. Determine whether it is a key signal for

As a result of the determination in step S200, when it is determined that the key signal for the aging mode is performed, the microcomputer 102 proceeds to step S202 to determine whether the time required for the aging process has elapsed.

As a result of the determination in step S202, if the maturation time has not elapsed, the microcomputer 102 proceeds to step S204 to determine whether the compressor 104 is turned on, and if the maturation time has elapsed, performs the storage mode described later. do.

As a result of the determination in step S204, if the compressor 104 is not on, the process proceeds to step S208. If the compressor 104 is on, the process proceeds to step S206 to block the chamber A solenoid valve 106 and Proceed to step S208.

In step S208, the microcomputer 102 determines whether the chamber A driver 110 is turned on, and if the chamber A driver 110 is turned on, the microcomputer 102 proceeds to step S210, but the chamber A driver 110 is turned on. If not, the process proceeds to step S214.

In step S210, the microcomputer 102 determines whether the temperature data provided from the room A temperature sensor 114 exceeds the temperature data T1 stored in the memory unit 118, for example, 15 ° C.

If the temperature data measured by the room A temperature sensor 114 exceeds 15 ° C., the microcomputer 102 proceeds to step S212 to turn off the room A heater driving unit 110.

However, in step S214, the microcomputer 102 determines whether the temperature data provided from the room A temperature sensor 114 is less than the temperature data T2 stored in the memory unit 118, for example, less than 14 ° C., and is less than 14 ° C. If it is, the microcomputer 102 proceeds to step S216 to turn on the chamber A driving unit 110.

On the other hand, if it is determined in step S300 that the key signal provided from the key input unit 100 is a key signal for performing the storage mode, the microcomputer 102 proceeds to step S302 to determine whether the compressor 104 is on. If it is determined that the compressor 104 is on, the process proceeds to step S304, but if the compressor 104 is not on, the process proceeds to step S308.

In step S304, the microcomputer 102 determines whether the temperature data provided from the room A temperature sensor 114 is the temperature data T3 stored in the memory unit 118, for example, 5 ° C. or less.

If the temperature data to be measured is 5 ° C. or less, the microcomputer 102 proceeds to step S306 to turn off the compressor 104.

However, in step S308, the microcomputer 102 determines whether the temperature data provided from the room A temperature sensor 114 exceeds the temperature data T4 stored in the memory unit 118, for example, 6 ° C. If exceeded, the microcomputer 102 proceeds to step S310 to turn on the compressor 104.

On the other hand, if it is determined in step S400 that the key signal provided from the key input unit 100 is a key signal for performing the freezing mode according to the present embodiment, the microcomputer 100 proceeds to step S402 and the compressor If it is determined that 104 is on and the compressor 104 is on, the process proceeds to step S404, but if the compressor 104 is not on, the process proceeds to step S408.

In step S404, the microcomputer 100 determines whether the temperature data provided from the room A temperature sensor 114 is the temperature data T5 stored in the memory unit 118, for example, −22 ° C. or less.

If the measured temperature data is -22 ° C or less, the microcomputer 100 proceeds to step S406 to turn off the compressor 104.

However, in step S408, the microcomputer 100 determines whether the temperature data provided from the room A temperature sensor 114 exceeds the temperature data T6 stored in the memory unit 118, for example, -18 ° C. If it exceeds C, the microcomputer 100 proceeds to step S410 to turn on the compressor 104.

That is, the present invention is implemented to be driven in the freezing mode as well as the ripening / storage mode of the kimchi refrigerator by selectively controlling the drive of the compressor (104).
