Description

Driving Control Device and Method of Kimchi Storage

The present invention relates to a kimchi storage, and more particularly to a drive control apparatus and method of the kimchi storage that can be optimally refrigerated kimchi stored in the kimchi storage room by forcibly driving the compressor when the idle time of the compressor exceeds the set time. It is about.

In general, in order to store frozen and refrigerated foods or fermented foods (for example, kimchi, etc.), each of them should be stored at a temperature suitable for storing them. A refrigerator having a freezer and a refrigerating chamber is mainly used to perform this function. Used.

On the other hand, when the refrigerated food and the fermented food is stored together in the refrigerator compartment of the refrigerator, the odor generated by the fermentation of the fermented food not only generates odors in the refrigerating chamber, but also odor is exhausted in other refrigerated foods inherent in the refrigerated food There is a need to store bulky fermented foods (kimchi) in a separate reservoir due to the increase in refrigerated foods and fermented foods stored in the refrigerator compartment.

In addition, kimchi should be buried in the ground for proper ripening, and the kimchi should be stored in it to be ripe and taste properly. However, it is difficult to keep it in a residential area.

Recently, researches on kimchi storage that can store kimchi in a separate storage space, rather than a refrigerator, to solve the above-mentioned difficulties have been variously researched in various technical fields, such kimchi storage is generally 1 and As shown in FIG.

The kimchi storage as described above can be seen in reference to Figure 1, the door 20 is to be rotated in one direction to the upper surface of the main body 10 formed therein the kimchi storage room to be described later to open and close the kimchi storage room hinged Are combined.

In addition, at both side predetermined portions of the main body 10, a handle 30 is provided to allow a user to grip the main body 10 when the main body 10 moves.

In addition, the bottom surface front portion of the main body 10 is provided with a horizontal adjusting leg 40 for adjusting the horizontality of the main body 10, the bottom surface rear portion of the main body 10 the main body 10 Wheel 50 is installed to be rotated when the movement of the).

In addition, a predetermined portion of the upper surface of the door 20 is provided with a key input unit 60 for setting an operation mode of the kimchi storage and adjusting the temperature of the kimchi storage room according to a user's preference. The front handle 20 is provided with a door handle 70 so that the user can easily grip when opening and closing the door 20.

Here, the inside of the main body 10, as shown in Figure 2, the kimchi storage chamber 80, and the machine room 90 is installed, the compressor 91 and the control box 92, etc. are stored Kimchi storage container Each partition is formed by a partition wall 11 made of a heat insulating material, and an evaporator 81 is inserted into the outer partition wall 11 of the kimchi storage chamber 80 to generate cold air by using latent evaporation generated when the refrigerant is vaporized. It is installed.

Here, a control unit for controlling the driving of the compressor 91 is built in the control box 92.

In addition, the bottom sensor 11 at the point where the inlet refrigerant pipe 81a of the evaporator 81 is installed, the temperature sensor 100 detects the metal pipe 101 indirectly to detect the internal temperature of the kimchi storage chamber 80. It is installed as an intermediary.

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

In the initial state, when the user selects the "cold storage mode" through the key input unit 60, the compressor 91 is driven by the control unit in the control box 92, the refrigerant by the drive of the compressor 91 The cycle is circulated to supply the refrigerant to the evaporator 81, and as the refrigerant supplied to the evaporator 81 evaporates, cold air is generated and the kimchi storage chamber 80 is cooled by the cold air.

At this time, the ambient temperature of the evaporator 81 is detected through the temperature sensor 100, a temperature signal corresponding to the detected ambient temperature of the evaporator 81 is applied to the control unit, the control unit from the temperature sensor 100 The ambient temperature of the evaporator 81 is sensed through the applied temperature signal.

Then, the control unit maintains the driving state of the compressor 91 when the detected ambient temperature of the evaporator 81 is equal to or higher than the "compressor operation" temperature, while the ambient temperature of the detected evaporator 81 is "compressor." When the temperature is lower than the "stop" temperature, the compressor 91 is stopped.

That is, the compressor 91 is driven by indirectly detecting the internal temperature of the kimchi storage chamber 80 through the ambient temperature of the evaporator 81 detected by the temperature sensor 100.

It is a graph showing the average temperature inside the kimchi storage chamber 80 according to the driving state of the compressor 91 that is operated as shown in c).

However, since the temperature sensor 100 is installed on the side of the evaporator 81 in the partition 11 forming the kimchi storage chamber 80 and is affected by external temperature, when the kimchi storage is installed outdoors, such as an apartment porch. As can be seen with reference to (c) of FIG. 3, it can be seen that the time at which the driving of the compressor 91 is stopped (hereinafter, referred to as “pause time”) changes according to seasons, and is particularly long in winter. .

In detail, as can be seen with reference to Figure 3 (d), in the summer, spring and autumn, the internal temperature of the kimchi storage room 80 is kept constant at the set refrigerated storage temperature without large deviation within the kimchi storage room (80) Although the stored kimchi is optimally refrigerated, when the external temperature is low, such as winter, the idle time of the compressor 91 exceeds an appropriate time, so that the internal temperature of the kimchi storage room 80 is increased and stored in the kimchi storage room 80. There was a problem that kimchi is over ripened.

Therefore, the present invention has been made to solve the problems of the prior art as described above, even if the ambient temperature of the evaporator detected by the temperature sensor does not reach the compressor operating temperature if the idle time of the compressor exceeds the set time It is an object of the present invention to provide a drive control apparatus and a method of a kimchi storage, which can prevent the kimchi stored in the kimchi storage room from being over-matured by forcibly driving the compressor.

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

4 is a schematic block diagram of a driving control apparatus for a kimchi storage according to a preferred embodiment of the present invention. The driving control apparatus for a kimchi storage according to the present invention includes a key input unit 60 and a temperature sensor 100. And, the control unit 230, the compressor driving unit 240, and the compressor 91, the basic configuration for the drive control device of the kimchi storage shown in the same drawing is shown in the kimchi storage shown in Figs. Since they are the same, the same reference numerals are used for the same parts, and duplicate descriptions will be omitted.

In FIG. 4, the operation mode setting unit 210 includes a plurality of selection buttons for setting the operation mode of the kimchi storage, and converts a button operation by the user into a corresponding key signal to control the controller 230. To be applied to.

In addition, the date input unit 220 includes a plurality of numeric buttons for inputting a date, and converts a button operation by a user into a corresponding key signal and applies it to the controller 230.

When the user selects the "cold storage mode" through the operation mode setting unit 210, the controller 230 drives the compressor 91 to be turned on / off according to the temperature signal input from the temperature sensor 100. It is supposed to output a signal.

In addition, the controller 230 applies a display signal corresponding to the date input by the user through the date input unit 220 to the display unit 250 to be described later, and determines the season according to the date input by the user. When the season is winter, even if the ambient temperature of the evaporator 81 detected by the temperature sensor 100 does not reach the "compressor operation" temperature, when the idle time of the compressor 91 becomes longer than the set time tE, the compressor 91 Outputs a drive signal for operating.

In addition, the compressor driver 91 is configured to drive the compressor 91 by applying power to the compressor 91 according to a driving signal applied from the controller 230, and the display unit 250 is applied from the controller 230. According to the display signal, a message for instructing a date input and a date input by the user are displayed.

5 (a) to (d) is a view for explaining the correlation between the average temperature of the season when the kimchi storage to which the present invention is applied and the average temperature inside the kimchi storage room, Figure 5 (a) ) Is a graph showing the average outdoor temperature by season, Figure 5 (b) is a graph showing the ambient temperature of the evaporator 81 is detected through the temperature sensor 100, Figure 5 (c) is the temperature sensor. A graph illustrating a driving state of the compressor 91 according to the ambient temperature of the evaporator 81 sensed through the reference numeral 100, and FIG. 5D illustrates a compressor operated as shown in FIG. 5C. 91) is a graph showing the average temperature inside the kimchi storage chamber (80) according to the driving state.

An operation process of the present invention configured as described above will be described in detail with reference to FIGS. 4 to 6.

First, when power is applied from the outside, the controller 230 is initialized (S10).

At this time, when the user selects the operation mode (for example, the ripening mode and the refrigerated storage mode) through the operation mode setting unit 100, corresponding to the operation mode selected by the user from the operation mode setting unit 100 The key signal is applied to the controller 230.

Herein, the controller 230 determines whether the operation mode selected by the user is the "cold storage mode" through the key signal applied from the operation mode setting unit 100 (S20), and the determination result is that the operation mode selected by the user is "refrigerated". If it is not in "storage mode", the control operation ends.

As a result of the determination in step S20, if the operation mode selected by the user is the "cold storage mode", the control unit 230 applies a display signal for displaying a message instructing the date input to the display unit 250, and then the date. It is determined whether a key signal is input from the input unit 220 (S30).

At this time, when the user inputs the date by operating the numeric buttons of the date input unit 220, the corresponding key signal is applied from the date input unit 220 to the control unit 230, and the control unit 230 from the date input unit 220. By identifying the date input by the user through the authorized key signal, the current season is determined according to the identified date (S40).

Next, the controller 230 determines whether the season determined in the step S40 is winter (S50), and if it is not the winter season, the controller 230 operates the compressor 91 according to a temperature signal applied from the temperature sensor 100. By maintaining the temperature of the kimchi storage room 80 to the set temperature (S60), the detailed operation process thereof is the same as in the prior art and the duplicated description will be omitted.

If it is determined in step S50 that the current season is winter, the controller 230 applies a drive control signal for driving the compressor 91 to the compressor driver 240 (S70).

Thus, power is applied to the compressor 91 through the compressor driver 240 according to the drive control signal applied from the controller 240, and the compressor 91 to which power is applied is driven.

The refrigerant is circulated by the operation of the compressor 91, and the refrigerant circulated through the compressor 91 is supplied to the evaporator 81, and the refrigerant supplied to the evaporator 81 is applied to the latent heat of evaporation generated while vaporizing. Cold air is generated, and the inside of the kimchi storage chamber 80 is cooled by the cold air generated in the evaporator 81.

At this time, a temperature signal corresponding to the ambient temperature of the evaporator 81 is applied to the control unit 230 from the temperature sensor 100, the control unit 230 is the evaporator 81 through the temperature signal applied from the temperature sensor 100. The ambient temperature of the sensor is detected. (S75)

Then, the controller 230 determines whether the ambient temperature of the evaporator 81 detected in the step S75 is lower than the "compressor stop" temperature (S80), and the determination result indicates that the ambient temperature of the evaporator 81 is " If the compressor stop " temperature is exceeded, the process proceeds to the step S70 to maintain the driving state of the compressor 91.

If the ambient temperature of the evaporator 81 is equal to or lower than the "compressor stop" temperature as a result of the determination in step S80, the compressor 230 supplies a drive control signal for stopping the compressor 91 by the controller 230. It is applied to (S90).

As a result, the power supply applied to the compressor 91 through the compressor driver 240 is interrupted according to the driving control signal applied from the controller 230, thereby stopping the driving of the compressor 91.

Then, the controller 230 detects the ambient temperature of the evaporator 81 through the temperature signal applied from the temperature sensor 100 (S95), so that the detected ambient temperature of the evaporator 81 is the temperature of the "compressor operation" temperature. If it is the above, it progresses to the following step S130 which operates the compressor 91.

If the ambient temperature of the evaporator 81 is less than the "compressor operation" temperature as a result of the determination in step S95, the controller 230 stops driving of the compressor 91 from the step S90. The idle time of the compressor 91 is checked (S110), and it is determined whether the idle time of the checked compressor 91 is greater than or equal to the set time tE (S120).

Here, the set time (tE) is to install the kimchi storage outside of the apartment porch, etc., and then continuously measure the idle time (see (c) of FIG. 5) of the compressor 91 that changes according to each season, It is a value set not to exceed the idle time measured as the longest time of the idle time of the compressor 91 measured in summer, spring, and autumn.

If it is determined in step S120 that the idle time of the compressor 91 is less than the set time tE, the controller 230 proceeds to step S95 and the subsequent steps S95 to S120. Perform iteratively.

If it is determined in step S120 that the idle time of the compressor 91 is equal to or greater than the set time tE, the controller 230 transmits a drive control signal for driving the compressor 91 to the compressor driver 240. It is applied (S130).

As a result, power is applied to the compressor 91 through the compressor driver 240 according to the driving control signal applied from the controller 230, and the compressor 91 to which power is applied is driven.

The refrigerant is circulated by the operation of the compressor 91, and the refrigerant circulated through the compressor 91 is supplied to the evaporator 81, and the refrigerant supplied to the evaporator 81 is applied to the latent heat of evaporation generated while vaporizing. As a result of the cold air generated in the evaporator 81, the kimchi storage chamber 80 is cooled.

That is, even when the idle time of the compressor 91 in the winter time is longer than the set time tE, when the ambient temperature of the evaporator 81 detected by the temperature sensor 100 is less than the "compressor operation" temperature, the kimchi storage Is installed outdoors and the ambient temperature of the evaporator 81 detected by the temperature sensor 100 according to the cold outside temperature of the winter is lower than the internal temperature of the kimchi storage chamber 80, the downtime of the compressor 91 is Since the state exceeds the appropriate time, the compressor 91 is forcibly driven to prevent over-maturation of the kimchi stored in the kimchi storage chamber 80.

Then, the controller 230 detects the ambient temperature of the evaporator 81 through the temperature signal applied from the temperature sensor 100 (S135).

Then, the controller 230 determines whether the ambient temperature of the evaporator 81 detected in the step S135 is equal to or lower than the "compressor stop" temperature (S140), and the determination result indicates that the ambient temperature of the evaporator 81 is " If the compressor stop " temperature is exceeded, the process proceeds to the step S130 to maintain the driving state of the compressor 91.

If the ambient temperature of the evaporator 81 is equal to or lower than the "compressor stop" temperature as a result of the determination in step S140, the compressor 230 supplies a drive control signal for stopping the compressor 91 by the controller 230. It is applied to (S150).

As a result, the power supply applied to the compressor 91 through the compressor driver 240 is interrupted according to the driving control signal applied from the controller 230, thereby stopping the driving of the compressor 91.

Next, the controller 230 determines whether the main power switch shown in the drawing is turned off (S160), and if the main power switch is not turned off, detecting the ambient temperature of the evaporator 81 (S95). The process proceeds to step S95 to step S160 repeatedly, and when the main power switch is turned off, the control operation ends.

As described above, the present invention is based on the date input by the user, even if the ambient temperature of the evaporator 81 detected by the temperature sensor 100 in winter time does not reach the "compressor operation" temperature, the idle time of the compressor 91 Compressor 91 is forcibly driven when the set time tE is exceeded so as not to exceed the maximum idle time measured in summer, spring, and autumn. As shown in FIG. Even if the ambient temperature of the evaporator 81 does not reach the "compressor operation" temperature for a long time when the ambient temperature of the evaporator 81 exceeds the appropriate idle time of the compressor 91 by the external air temperature, The internal temperature can be kept constant at the set temperature.

Therefore, by using the present invention, even if the ambient temperature of the evaporator detected by the temperature sensor in winter does not reach the compressor operating temperature, if the idle time of the compressor exceeds the set time, the compressor is forcibly driven so that the idle time of the compressor is increased. As the internal temperature of the kimchi storage room is increased, the stored kimchi can be prevented from being over mature.
