Description

Operation Control System and Method of Kimchi Storage {APPARATUS AND METHOD FOR CONTROLLING OPERATION IN A KIMCHI STOREHOUSE}

The present invention relates to an operation control apparatus and method of a kimchi storage, and more particularly, to an operation control apparatus and method of a kimchi refrigerator for cooling operation from the storage room with a high internal temperature in order to reduce the load of the overloaded compressor.

In general, the Kimchi storage room is equipped with a storage room for food such as kimchi, vegetables, etc.In order to maintain the internal temperature of the storage room at a temperature suitable for cold storage and to mature the food stored in the storage room, a freezing cycle and a ripening heater are installed around the storage room. have.

However, since the storage room for refrigerating kimchi is provided with a structure that also serves as a ripening room, when the previously stored kimchi and newly made kimchi are stored together, the existing kimchi becomes excessively fermented and loses its taste. .

In view of this, two storage compartments are provided inside the main body of the kimchi storage, and the existing kimchi is stored in one storage compartment under ripening conditions, and the new kimchi is stored and stored in another storage compartment.

As such, in the kimchi storage provided with two storage chambers, a refrigeration cycle including one compressor and two evaporators is generally applied as shown in FIG. 1. That is, two evaporators 7A and 7B are installed in the compressor 1 in parallel, and are mainly installed by bending the first evaporator 7A a plurality of times between the inner wall and the outer wall of the first storage chamber provided above the main body. The second evaporator 7B is bent and installed a plurality of times between the inner wall and the outer wall of the second storage chamber provided below the main body. Then, the first and second capillary tubes 6A and 6B are disposed upstream of the first evaporator 7A and the second evaporator 7A, respectively, and the refrigerant is located upstream of the first and second capillary tubes 6A and 6B. First and second solenoid valves 5A and 5B are provided for controlling the flow, respectively. At this time, the first and second solenoid valves 5A and 5B are two-way open / close valves, while the refrigerant flow is maintained at the time of opening while the refrigerant flow is closed at the time of closing. The condenser 3 is provided between the compressor 1 and the first and second solenoid valves 5A and 5B, and the auxiliary condenser 2 and the dryer 4 are provided before and after the condenser 3. have.

In the Kimchi storage, the temperature sensor installed in each storage compartment detects the internal temperature of each storage compartment and compares it with a preset set temperature to determine whether the cooling operation is performed. That is, when the internal temperature of the first storage compartment becomes higher than the set temperature due to the food inflow and door opening and closing of kimchi, the internal temperature of the first storage compartment is lowered by opening the first solenoid valve 5A for driving the compressor 1. To do that. Similarly, when the internal temperature of the second storage compartment becomes higher than the set temperature, the compressor 1 is driven and the second solenoid valve 5B is opened to lower the internal temperature of the second storage compartment. When the internal temperature of the first storage chamber and the second storage chamber is higher than the set temperature, the compressor 1 is driven and the first and second solenoid valves 5A and 5B are opened to perform the cooling operation. do. The operating capacity of the compressor 1 is designed to allow the first storage chamber and the second storage chamber to be cooled together.

However, if the outside air temperature is high and a large amount of food is stored in each storage room as in summer, and the compressor 1 is continuously operated for a long time, the operation efficiency of the overloaded compressor 1 is reduced, and thus the internal temperature of each storage room is reduced. The speed of dropping is slowed down. In addition, as the surface temperature of the compressor 1 rises excessively, the overload relay OLP installed to protect the compressor shuts off the power supply and stops the compressor operation. Then, the compressor 1 is restarted. Since the cooling operation for each storage room is interrupted for a long time, the freshness of the stored food is reduced and power consumption is increased.

Moreover, since the Kimchi refrigerator is installed in a narrow space, the compressor is easily overloaded in an environment where the cooling of the compressor is not smoothly performed. Therefore, the operation efficiency of the compressor is frequently decreased and the operation stops frequently. There was a problem floating down.

An object of the present invention is to improve the operation efficiency of the compressor by reducing the load of the overloaded compressor in the kimchi refrigerator having one compressor and two evaporators to improve the operation efficiency and reduce the power consumption of the Kimchi refrigerator operation control apparatus and method In providing.

Figure 2 is a block diagram of the operation control device of the kimchi storage in accordance with the present invention. As shown, the present invention includes first and second temperature detectors 10 and 20 for detecting internal temperatures of the first and second storage compartments that are divided into upper and lower parts of the main body. The first temperature detector 10 may include a first thermistor 10a whose resistance value is changed according to the internal temperature of the first storage chamber, and a first voltage divider 10b connected between one side of the first thermistor 10a and the ground. ) And one side of the second voltage divider resistor 10c connected between the first thermistor 10a and the input side of the microcomputer 40 and the connection point of the second voltage divider resistor 10c and the microcomputer 40 and the other side thereof. A grounded first capacitor 10d is formed. The second temperature detector 20 may include a second thermistor 20a whose resistance value is changed according to the internal temperature of the second storage chamber, and a third voltage divider 20b connected between one side of the second thermistor 20a and the ground. ) Is connected to the fourth divided resistor 20c and the connection point of the fourth divided resistor 20c and the microcomputer 40 connected between the second thermistor 20a and the input side of the microcomputer 40 and the other side thereof. It is made of a grounded second capacitor 20d. The microcomputer 40 determines whether to perform a cooling operation of the storage chamber by comparing the internal temperature detected by the first and second temperature detectors 10 and 20 with the preset internal temperature of each storage chamber.

In addition, the present invention is characterized by having an external air temperature detection unit 30 is connected to the input side of the microcomputer 40. The outside air temperature detector 30 may include a third thermistor 30a having a resistance value that varies according to the outside air temperature around the compressor 1, and a fifth divided resistor connected between one side of the third thermistor 30a and ground. 30b) and one side of the sixth voltage divider 30c and the connection point of the sixth voltage divider 30c and the microcomputer 40 connected between the third thermistor 30a and the input side of the microcomputer 40, and the other side thereof. The grounded fourth capacitor 30d is formed. When the outside air temperature around the compressor 1 rises, the resistance value of the third thermistor 30a decreases and is divided by the fifth and sixth voltage divider resistors 30b and 30c and thus inputted to the microcomputer 40. The voltage value becomes large. At this time, the microcomputer 40 recognizes the outside temperature according to the voltage value corresponding to the resistance value of the third thermistor 30, and determines the compressor overload condition by comparing with the preset reference temperature.

In addition, the first evaporator 7A is bent and installed a plurality of times between the inner wall and the outer wall of the first storage chamber, and the first mature heater 70 is embedded in the vicinity of the first evaporator 7A. In addition, the second evaporator 7B is bent and installed a plurality of times between the inner wall and the outer wall of the second storage chamber, and the second mature heater 100 is embedded in the vicinity of the second evaporator 7B. The first inverter 50 and the first relay switch 60 are connected in series between the first mature heater 70 and the output side of the microcomputer 40, and are connected to the output side of the second mature heater 100 and the microcomputer 40. The second inverter 80 and the second relay switch 90 are connected therebetween. The heater control signal output from the microcomputer 40 to operate the first mature heater 70 is inverted by the first inverter 50, whereby the excitation coil 60a of the first relay switch 60 is excited. When the first iron piece 60b is turned on and the power source AC 220V is supplied, the first mature heater 70 generates heat. In addition, the second mature heater 100 also generates heat when power is supplied by the heater control signal of the microcomputer 40. That is, the first and second ripening heaters 70 and 100 are operated by the microcomputer 40 to maintain the proper temperature required for ripening the stored food in each storage compartment, and the conventional control in the kimchi storage. Since the operation is followed, a detailed description thereof will be omitted.

A third inverter 110 and a third relay switch 120 are connected between the output side of the microcomputer 40 and the first solenoid valve 5A, and the output side of the microcomputer 40 and the second solenoid valve 5B. The fourth inverter 140 and the fourth relay switch 150 are connected therebetween. The valve control signal output from the microcomputer 40 to operate the first solenoid valve 5A is inverted by the third inverter 110, whereby the excitation coil 120a of the third relay switch 120 is excited. When the third iron piece 120b is turned on and the power supply AC 220V is supplied, the first solenoid valve 5A is opened. The second solenoid valve 5B is also opened when power is supplied by the valve control signal of the microcomputer 40. That is, the first and second solenoid valves 5A and 5B are operated by the microcomputer 40 to maintain the appropriate temperature required for refrigerated storage of each storage compartment.

The first and second solenoid valves 5A and 5B are directly connected to upstream sides of the first and second evaporators 7A and 7B, respectively, to the microcomputer 40 when performing a cooling operation of each storage chamber. And the refrigerant passing through the condenser 3 and the dryer 4 are circulated to the first and second evaporators 7A and 7B via the first and second capillary tubes 6A and 6B.

The fifth inverter 170 and the fifth relay switch 180 are connected between the output side of the microcomputer 40 and the compressor 1, and the compressor control signal output from the microcomputer 40 is the fifth inverter 70. When the excitation coil 180a of the fifth relay switch 180 is excited, the fifth iron piece 180b is turned on so that the compressor 1 is driven as power is supplied. At this time, the microcomputer 40 counts the compressor operation time after outputting the compressor control signal to stop the compressor 1 to drive the compressor 1, and overloads based on the counted continuous operation time of the compressor. Determine the condition.

In the present invention, the microcomputer 40 is divided into the normal operation mode and the overload operation mode to perform the cooling operation for the first and second storage chambers, the microcomputer 40 in the normal operation mode according to the ambient temperature and the compressor continuous operation time Or it determines the overload operation mode.

In the normal operation mode, the microcomputer 40 drives the compressor 1 and operates the first solenoid valve 5a when the internal temperature of the first storage chamber detected by the first temperature detector 10 becomes higher than the set temperature. The refrigerant is circulated to the first evaporator 7A to perform a cooling operation. Similarly, when the internal temperature of the second storage chamber detected by the second temperature detector 20 becomes higher than the set temperature, the compressor 1 is opened. After driving, the second solenoid valve 5B is opened to circulate the refrigerant to the second evaporator 7B to perform a cooling operation. In addition, when the internal temperature of the first and second storage chambers both rise above the set temperature, the compressor 1 is driven, and both the first and second solenoid valves 5A and 5B are opened to open the first and second chambers. Cooling operation is performed for the storage room.

As such, when the compressor overload condition is performed during the cooling operation according to the normal operation mode, the cooling operation is performed on the first and second storage chambers according to the overload operation mode. That is, the microcomputer 40 periodically checks the outside temperature and the compressor continuous operation time, and accordingly, if the compressor overload condition corresponds to the overload operation mode according to FIG. 3.

Since the operation capability of the compressor 1 is designed to perform a cooling operation for the first and second storage chambers, the compressor operation is normally performed when the outside air temperature is higher than room temperature and is not relatively high. However, if a lot of food is brought into the storage room under the installation environment where it is difficult to cool the compressor because it is installed in a place where the outside air temperature is high and the ventilation is not smooth like summer, the compressor is overloaded because the compressor operation continues for a long time because the compressor operation capacity is exceeded. You're on condition.

When the compressor is overloaded, the microcomputer 40 suspends the compressor operation by turning off the fifth relay switch 180. In this embodiment, the compressor operation is stopped for about 5-6 minutes. If the compressor is left overloaded, the compressor will be overheated and the electrical parts (e.g., overload relay) to protect the compressor will be cut off from the power supply and the compressor will be stopped for a long time until the compressor is cooled down and supplied again. Therefore, the cooling operation for each storage compartment is not effectively performed, and to solve the waste of power consumption due to the restart of the compressor.

The microcomputer 40 restarts after temporarily stopping the operation of the compressor 1, and after restarting, the microcomputer 40 performs a cooling operation on any one storage room by comparing the internal temperature of each storage room and then cools the other storage room. Will drive. In this way, if the continuous operation time that counts the operation time of the compressor 1 during the cooling operation for each storage room elapses after the set time (for example, 30 minutes) has elapsed, the compressor operation is temporarily suspended and then any one storage room. Perform cooling operation on the target. Accordingly, since the load of the compressor 1 is reduced, the cooling operation can be performed according to its own driving ability.

Hereinafter, the operation control method of the kimchi storage according to the present invention will be described in detail according to a flow chart, the normal operation mode will be briefly described and the overload operation mode will be described.

In the normal operation mode, the microcomputer 40 periodically checks an operation of comparing the internal temperature of the first and second storage chambers with the set temperature detected by the first and second temperature detectors 10 and 20. As a result of the check, the cooling operation is performed on the storage compartment where the high internal temperature is higher than the set temperature. In this case, when the cooling operation is performed on the first and second storage chambers, the compressor 1 is driven while the first and second solenoid valves 5A and 5B are opened, and the microcomputer 40 operates the compressor. Count the time.

As described above, the microcomputer 40 determines whether the compressor is overloaded according to the ambient temperature and the compressor operation time during the normal operation mode (S100). As a result of the determination, when the outside temperature detected by the outside temperature detection unit 30 is equal to or greater than a preset reference temperature (for example, 60 ° C.) and the compressor continuous operation time counted is greater than or equal to the preset reference time (for example, 30 minutes), the compressor overload condition If it is not, it is determined to be in the normal operation mode.

When it is determined that the compressor is overloaded, the microcomputer 40 outputs a compressor control signal to the fifth inverter 170 so as to temporarily suspend the compressor operation, thereby turning off the fifth relay switch 180. Accordingly, the power supply is cut off and the compressor 1 is turned off (S101).

The microcomputer 40 outputs a valve control signal to the third and fourth inverters 110 and 140 when a predetermined time (for example, one minute) elapses after the compressor 1 is turned off. Both the first and second solenoid valves 5A and 5B which are kept open to circulate the refrigerant to the evaporators 7A and 7B are turned off.

After a predetermined time (for example, 4 minutes) has elapsed since the first and second solenoid valves 5A and 5B are turned off, the microcomputer 40 sends a valve control signal to the third and fourth inverters 110 and 140. The first and second solenoid valves 5A and 5B that are kept closed and turned on (S103), and then restart the compressor 1 after a predetermined time (e.g., 1 minute) has elapsed. In order to output the compressor control signal to the fifth inverter 170, the fifth relay switch 180 is turned on. Accordingly, operation of the compressor 1 is started as power is supplied (S104).

Subsequently, the microcomputer 40 detects the internal temperature of the first storage chamber detected by the first temperature detector 10 and the second temperature detector 20 to determine one storage chamber to perform a cooling operation. 2 Compare the internal temperature of the storage compartment (S105).

If the internal temperature of the second storage compartment is higher than the internal storage temperature of the first storage compartment in step S105, the microcomputer 40 turns off the third relay switch 120 and performs a fourth relay at the same time to cool the second storage compartment. The switch 150 is turned on to supply the refrigerant to the second evaporator 7B (S106). The refrigerant is supplied to the second evaporator 7B, so that the internal temperature of the second storage compartment falls, and the microcomputer 40 determines whether the second internal temperature satisfies the set temperature (S107). If the temperature does not satisfy the set temperature, it is determined whether the continuous operation time of the compressor 1 has passed the set time (for example, 30 minutes) (S108). As a result of the determination in step S108, when the compressor operation time has not passed the set time, the flow returns to step S106 to continue the cooling operation of the second storage chamber, and when the compressor operation time has passed the set time, the load of the compressor 1 The flow returns to step S101 to reduce.

When the second internal temperature satisfies the set temperature as a result of the determination in step S107, the microcomputer 40 performs a third operation to complete the cooling operation for the second storage chamber and then perform the cooling operation for the first storage chamber. At the same time, the relay switch 120 is turned on and the fourth relay switch 150 is turned off to supply the refrigerant to the first evaporator 7A. Accordingly, the internal temperature of the first storage compartment is decreased (S109). The microcomputer 40 determines whether the first internal temperature satisfies the set temperature (S110). If the first internal temperature does not satisfy the set temperature, the microcomputer 40 determines that the continuous operation time of the compressor 1 is the set time (example). 30 minutes) has passed (S111). As a result of the determination in step S111, when the compressor operation time has not passed the set time, the flow returns to step S109 to continue the cooling operation of the first storage chamber, and when the compressor operation time has passed the set time, the load of the compressor 1 The flow returns to step S101 to reduce.

As a result of the determination in step S110, when the first internal temperature satisfies the set temperature, the microcomputer 40 generates a relay control signal for turning off the third relay switch 120 to block the flow of the refrigerant to the first evaporator 5A. After outputting to the third inverter 110 to turn off the first solenoid valve 5A (S112), the compressor control signal for turning off the fifth relay switch 180 is output to the fifth inverter 170 to provide a compressor ( 1) is turned off (S113). Thereafter, the process proceeds to the normal operation mode to perform the cooling operation according to the internal temperature of each storage compartment.

On the other hand, if the internal temperature of the second storage chamber is not higher than the internal temperature of the first storage chamber in step S105, the cooling operation is performed on the first storage chamber and then the cooling operation is performed on the second storage chamber. That is, the microcomputer 40 turns on the third relay switch 120 and at the same time turns off the fourth relay switch 150 to perform a cooling operation on the first storage chamber (S114). The microcomputer 40 determines whether the first internal temperature satisfies the set temperature (S115). If the first internal temperature does not satisfy the set temperature, the microcomputer 40 determines that the continuous operation time of the compressor 1 is the set time (example). 30 minutes) has passed (S116). As a result of the determination in step S116, when the compressor operation time has not passed the set time, the flow returns to S114. When the compressor operation time has passed the set time, the flow returns to step S101 to reduce the load on the compressor 1. As a result of the determination in step S115, when the first internal temperature satisfies the set temperature, the cooling operation for the first storage chamber is completed, and the microcomputer 40 turns off the third relay switch 120 and at the same time, the fourth relay switch 150. On) to perform a cooling operation for the second storage compartment (S117). The microcomputer 40 determines whether the second internal temperature satisfies the set temperature (S118). If the second internal temperature does not satisfy the set temperature as a result of the determination, the continuous operation time of the compressor 1 is the set time (example 30 minutes) has passed (S119). As a result of the determination in step S119, when the compressor operation time has not passed the set time, the flow returns to step S117 to continue the cooling operation of the second storage chamber, and when the compressor operation time has passed the set time, the load of the compressor 1 The flow returns to step S101 to reduce.

As a result of the determination in step S118, when the second high internal temperature satisfies the set temperature, the microcomputer 40 outputs a relay control signal for turning off the fourth relay switch 150 to the fourth inverter 140 to display the second solenoid valve ( After 5B is turned off (S120), the compressor 1 is output to the fifth inverter 170 to turn off the fifth relay switch 180 (S121). Thereafter, the process proceeds to the normal operation mode to perform the cooling operation according to the internal temperature of each storage compartment.

In the above-described embodiment, the cooling operation of the two storage compartments is sequentially performed when the overload condition is applied. However, in the initial operation, the two storage compartments are used for the purpose of maintaining the high temperature inside each storage compartment for the food storage. The cooling operation of any one of the storage compartments may be performed and then the cooling operation of the remaining storage compartments may be performed, and a person having ordinary skill in the art may easily understand the same without a detailed description.

As described above, in the present invention, when the outside temperature is high and the compressor corresponds to an overload condition in which the compressor is continuously operated for a long time, the compressor load is reduced by temporarily suspending the compressor operation and then performing a cooling operation from the storage compartment having a high internal temperature. Cooling operation can be performed accordingly. As a result, it is possible to maintain a good compressor operating efficiency at all times and to prevent the compressor from being stopped due to overheating, thereby increasing the reliability of the product.
