Description

Operation Control Device and Method of Kimchi Storage {APPARATUS AND METHOD FOR CONTROLLING OPERATION OF KIMCH'I STORE HOUSE}

The present invention relates to an operation control apparatus and method of the kimchi storage, and more particularly, to an operation control apparatus and method of the kimchi storage that can continue the operation performed before the power failure when the power failure occurs after the power return. will be.

In general, in order to store frozen foods, refrigerated foods and fermented foods (for example, kimchi, etc.), they should be stored at a temperature suitable for storing them, and a refrigerator having a freezer and a refrigerating chamber is mainly used to perform these functions. Was used.

However, when the refrigerated food and the fermented food are stored together in the refrigerator, the odor is generated in the refrigerating chamber due to the smell of the fermented food. As the number of refrigerated foods and fermented foods to be refrigerated can increase, there is a need to store relatively bulky fermented foods (kimchi) in separate storage.

In addition, kimchi can be properly seasoned by burying it in the ground and ripening it at the proper temperature conditions.However, due to the limitations of the residential environment such as apartments and townhouses, it is difficult to keep it in the ground. It is difficult.

Recently, in order to solve the above problems, research on kimchi storage that can store kimchi in a separate storage space, rather than a refrigerator, has been variously studied in various technical fields related thereto. As shown in FIG.

The appearance of the kimchi storage as described above, as shown in Figure 1, the kimchi storage room to be described later to be stored largely kimchi is formed therein, and the kimchi on the upper side of the main body 10 The door 20 is hinged to be rotatable to open and close the storage compartment.

On both sides of the main body 10, the handle 30 is installed so that the user can easily pull the main body 10 when moving the kimchi storage, and the main body (on the bottom surface of the main body 10) 10) is provided with a horizontal adjustment leg 40 for adjusting the horizontal, the bottom portion of the bottom surface of the main body 10 is attached to the wheel 50 that is rotated when moving the kimchi storage.

A predetermined portion of the upper surface of the door 20 is provided with a key input unit 60 is attached to freely set the operation mode of the kimchi storage and the refrigerated storage temperature of the kimchi according to the user's preference, the front of the door 20 The door handle 70 is installed so that the user can easily open and close the door 20.

Here, as shown in FIG. 2, a compressor 12 is installed at a lower portion of the main body 10 to compress the refrigerant at high temperature and high pressure, and then circulate it, and inside one side wall of the main body 10. There is a temperature sensor 14 for sensing the internal temperature of the inside of the refrigerator, a heater 17 for generating heat to raise the internal temperature in the refrigerator, and an evaporator 18 for cooling the internal temperature of the refrigerator by generating cold air. Each is installed.

The operation process of the kimchi storage configured as described above is as follows.

First, the user stores the kimchi in the storage of the storage body 10, and then operates the key input unit 60 to operate the operation conditions (aging mode such as ripening mode and refrigerated storage mode, kimchi type and ripening degree in the ripening mode). And a maturing speed, etc.), a key signal corresponding to the selected driving condition is input to the controller not shown, and the controller determines the driving condition selected by the user based on the key signal input from the key input unit 60. Operate Kimchi storage according to the operating conditions.

For example, in the aging mode, the internal temperature of the storage main body 10 is at a aging temperature (about 23 ± 2 ° C. for fast aging, usually about 8 ± 2 ° C. for rapid aging) by the heat generated from the heater 17. After being raised, the internal temperature in the refrigerator is maintained at the ripening temperature by the heat generated from the heater 17 and the cold air generated from the evaporator 18, whereby the kimchi stored in the main body 10 is aged.

In the refrigerating storage mode, the internal temperature of the main body 10 is maintained at the refrigerating storage temperature (for example, about 0 ° C.) by the cool air generated from the evaporator 18 while the refrigerant is circulated by the operation of the compressor 12. After cooling, the internal temperature in the refrigerator is maintained at the cold storage temperature by the heat generated from the heater 17 and the cold air generated from the evaporator 18, whereby the kimchi stored in the main body 10 is refrigerated.

However, in the conventional Kimchi storage as described above, when a power failure occurs during operation according to an operation condition set by the user, the operation information stored in the buffer memory on the printed circuit board or inside the controller is lost. Previously, the operation was not carried out continuously, the kimchi stored in the interior of the refrigerator is not optimally stored and aged, as well as the inconvenience that the user has to re-enter the operating conditions.

In particular, if the user enters the driving conditions again after a power failure during the aging mode, the kimchi is over ripened as the kimchi must be matured again according to the ripening course from the beginning while the kimchi has already matured for a predetermined time. There was a problem.

Accordingly, the present invention has been made to solve the problems of the prior art as described above, and when the operation information such as the operation mode or the operation progress state is stored in the nonvolatile memory device and the power is restored after the power failure, the nonvolatile By continuously operating according to the operation information prior to the power failure stored in the memory device of the present invention, to provide an operation control device and method of the kimchi storage that can be optimally refrigerated and stored stored kimchi even if a temporary power failure occurs during operation The purpose is.

Since the external appearance and internal structure of the kimchi storage to which the present invention is applied are the same as those of FIGS. 1 and 2, the same reference numerals are assigned to the same components, and duplicate descriptions thereof will be omitted.

In FIG. 3, the key input unit 100 includes a plurality of input conditions for inputting driving conditions (for example, the operation mode such as the refrigerated storage mode and the ripening mode and the kimchi type and the ripening degree and the ripening speed during the ripening mode). It is configured to include a selection button, the user inputs the corresponding key signal to the control unit 120 when the user operates the selection button, the temperature detection unit 110 detects the internal temperature of the main body 10 is detected inside The temperature signal corresponding to the temperature is input to the controller 120.

The controller 120 outputs a control signal for selectively driving the compressor 12 or the heater 17 according to an operation condition set by the user through the key input unit 100, and a program for driving the kimchi storage. And a ROM table 121 in which data, data, and the like are stored, and a buffer memory 122 for storing operation information including operation conditions set by the user.

The auxiliary memory unit 130 includes a nonvolatile memory device (for example, "EEP-ROM"), and the operation condition and the operation progress set by the user by the control signal from the control unit 120. Stores operation information such as the situation.

The compressor driver 140 is driven by applying power to the compressor 12 by a control signal from the controller 120, the heater driver 150 is a heater 17 by the control signal from the controller 120 Power is applied to drive.

An operation example of the present invention configured as described above will be described in detail with reference to FIGS. 3 and 4.

First, when power is applied to each part of the kimchi storage from a predetermined power supply source (for example, a commercial AC power supply), the control unit 120 is initialized (S10), and the initialized control unit 120 generates a new operating condition by the user. It is determined whether this is set (S20).

That is, in step S20, the user operates the selection button of the key input unit 100 to operate the driving conditions (for example, the operation mode such as the ripening mode and the refrigerated storage mode and the kimchi type and the ripening degree and the ripening mode in the ripening mode. Speed), a corresponding key signal is input to the control unit 120, and the control unit 120 determines the operation condition newly set by the user based on the input key signal and stores the determined operation condition in the built-in buffer memory ( 122) and the auxiliary memory unit 130 (S30).

Then, the controller 120 controls the control data (for example, the compressor operating temperature in the cooling storage mode, the compressor operating temperature in the aging mode, and the heater operating temperature in the aging mode) for performing the control operation of the operation condition newly set by the user. Etc.) and read out the built-in ROM table 121 to control operation of the kimchi storage according to the read control data (S40).

For example, when the user selects the ripening mode, the control unit 120 adjusts the internal temperature of the main body 10 to a ripening temperature (for example, about 23 ± 2 ° C. during fast ripening and about 8 ± 2 ° C. during normal ripening). The heater driving signal is output to raise the power to the heater, and power is applied from the heater driving unit 150 to the heater 17 by the heater driving signal from the control unit 120 to generate heat from the heater 17.

The internal temperature of the main body 10 is increased by the heat generated from the heater 17, and the internal temperature of the elevated body 10 is sensed by the temperature detecting unit 110, and thus the temperature inside the internal temperature of the main body 10 is increased. The temperature signal corresponding to the internal temperature of the main body 10 is output.

The temperature signal output from the temperature sensing unit 110 is input to the control unit 120 so that the control unit 120 determines the current inside temperature by the temperature signal, and if the determined inside temperature is the heater stop temperature, the heater 17 Outputs a heater drive stop signal for stopping driving of the &lt; RTI ID = 0.0 &gt;) &lt; / RTI &gt; and a compressor drive signal for driving the compressor 12.

The power applied to the heater 17 from the heater driving unit 150 is cut off by the heater driving stop signal from the control unit 120, so that the driving of the heater 17 is stopped, and the compressor driving from the control unit 120 is stopped. Power is applied from the compressor driver 140 to the compressor 12 by the signal, thereby driving the compressor 12.

The refrigerant is circulated by the operation of the compressor 12, and the circulating refrigerant is evaporated in the evaporator 18, whereby cold air is generated by latent heat of evaporation from the evaporator 18, thereby cooling the inside of the main body 10.

The control unit 120 determines the current internal temperature by the temperature signal from the temperature sensing unit 110 and stops driving the compressor 12 when the current internal temperature determined by the temperature of the compressor is the compressor stop temperature. And a heater driving signal for driving the heater 17.

The power applied to the compressor 12 from the compressor driving unit 140 is cut off by the compressor driving stop signal from the control unit 120, so that the driving of the compressor 12 is stopped, and the heater driving signal from the control unit 120 is stopped. As a result, power is applied from the heater driving unit 150 to the heater 17 to generate heat from the heater 17.

As described above, the controller 120 selectively drives the heater 17 and the compressor 12 to maintain the inside temperature of the body 10 at a maturing temperature, thereby ripening the kimchi stored in the inside of the body 10.

In addition, the control unit 120 stores the driving progress (for example, the time that the ripening mode is progressed) in the auxiliary memory unit 130 while driving the kimchi storage according to the operating conditions set by the user as described above. (S50).

After performing the step S50, if the power applied to the kimchi storage is not cut off, the process returns to the step S20 and operates the kimchi storage according to the currently set operating conditions until a new operating condition is set (S60). .

On the other hand, if it is determined in step S20 that a new driving condition is not set, the controller 120 controls the stored driving condition and the driving progress state before the power is supplied from the auxiliary memory unit 130, that is, before the power failure. In other words, the operation information is searched for (S70), and the search result determines whether the operation information before the power failure is stored (S80). Wait until the user sets a new operating condition.

If the operation result before the power failure is stored in the auxiliary memory unit 130 as a result of the determination in step S80, the controller 120 transfers the power failure according to the operation information before the power failure stored in the auxiliary memory unit 130. Continue to perform the operation that was performed until (S90).

For example, if the operation of the ripening mode before the power failure, the operation of the ripening mode stored in the auxiliary storage unit 130, followed by the operation of the ripening mode for the remaining ripening time, and then stored in the cold storage mode Switch to to perform the operation of cold storage mode.

Next, the controller 120 proceeds to step S50 of storing the progress of the operation performed so far in the auxiliary memory unit 130.

That is, according to the present invention, when the kimchi storage is operated according to the operating conditions set by the user, and the power is supplied again after the power supply is cut off by the power failure, the auxiliary memory unit 120 searches for the operation information before the power failure by power failure. According to the previous operation information, the operation that is in progress until the power failure is continuously performed.

As described above, according to the present invention, when power is supplied again after a power failure occurs, a temporary power failure occurs by continuously performing operations that were performed until the power failure according to the operation information stored in the nonvolatile memory device before the power failure. Even if the stored kimchi can be optimally refrigerated and matured, there is an effect that can eliminate the inconvenience of having to re-enter the operating conditions.
