Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for controlling a storage capable of storing items to be stored such as wine at an appropriate temperature and humidity.

[0002]

2. Description of the Related Art In order to preserve wine and to drink it deliciously, it is necessary to store wine under appropriate temperature and humidity conditions. For example, wine aging conditions,
In other words, the environment for saving is generally 12 to 16
It is said that a temperature range of ° C. is suitable. Further, it is known that the taste may be deteriorated if the width of the temperature change at this time is large, and it is important to keep the storage temperature substantially constant. In addition, when the cork dries and shrinks, the air enters the bottle and the flavor of the wine is impaired. Therefore, it is desirable to maintain an appropriate humidity (about 60 to 85% relative humidity) during storage. If the humidity is too high, there is a problem that mold is generated on the label.

On the other hand, the temperature at the time of drinking wine is different from the aging temperature. For example, at the time of drinking white wine or sparkling wine, the optimal temperature is 5 to 10 ° C., and red wine is lower than the temperature in the wine cellar. It is said that a slightly higher temperature of 16 to 20 ° C. is suitable.

[0004]

For this reason, small wine storages having a cooling function have appeared, and in small-scale restaurants, such wine storages are often installed to store wine. are doing. It is important to keep the humidity in the above range even in a small wine storage. In consideration of conditions such as summer when the outside air temperature is high, a cooler is required to maintain the above-mentioned appropriate temperature, and the cooling dehumidifies. Furthermore, if the outside air temperature is low and humidification is required, the humidification lowers the relative humidity. In this case, humidification is also required. Therefore, some kind of humidifying means is required in order to make the humidity range appropriate, and as an inexpensive means, an extra space is provided below the tray on which the wine bottle is mounted, and a flat plate-shaped humidifying tray is provided. Often.

Further, a humidifying tray is installed on the side wall of the storage room, and a tray for collecting condensed water (drain) generated in the cooler is provided in the air-conditioning room in which the cooler is housed. A method of humidifying with water is also being studied.

[0006] The method of humidifying by evaporation by providing a water level on such a tray has a simple structure and is inexpensive, but cannot control humidity accurately. For example, if there is a temperature range in which the cooler or the heater does not operate, the moisture will only evaporate from the tray in that temperature range, and the humidity will be too high. In addition, in order to efficiently control the temperature in the storage chamber, it is desirable to provide a fan to blow cool air or warm air. However, when only the heater is operating, dehumidification is not performed, and only evaporation from the tray is performed by blowing air. Because it is accelerated, the humidity will be too high even in this condition. Furthermore, even when a humidifying tray is not provided, the humidity may gradually increase due to factors such as evaporation of moisture attached to the surface of the storage object.

On the other hand, a humidifier such as an ultrasonic type for humidity control can be installed, but the cost increases.
Installation space is also required. In addition, the temperature and the humidity can be controlled by operating the cooler at all times to provide a dehumidifying function and adopting a method of controlling the temperature with a heater. However, in this control method, even though a cooler and a heater are unnecessary as temperature conditions, by operating them, power consumption is increased and running cost is increased.

Accordingly, an object of the present invention is to provide a method of controlling a storage, which does not make the configuration of the storage complicated and expensive, and can further control the humidity while suppressing power consumption.

[0009]

SUMMARY OF THE INVENTION Therefore, in the present invention, in a storage having a cooler and a fan capable of blowing cool air to a storage room, the cooler is stopped under a condition where a cooler is not necessary in terms of temperature. In such a state, the cooler is activated at regular intervals to dehumidify.
At this time, only the air conditioner room separated from the storage room is temporarily dehumidified by starting only the cooler without starting the fan, thereby preventing the storage room from being excessively dehumidified and reducing the temperature in the storage room. Try not to affect. That is, the storage of the present invention has a storage room, an air-conditioning room in which a cooler and a fan are housed, and at least cool air can be blown into the storage room, and further, a function of operating the cooler and the fan to perform cooling, and And control means having a function of operating the cooler with the fan stopped for a second time shorter than the first time when the cooler is not operating for a first time. Further, the method of controlling a storage room having a storage room and an air-conditioning room in which a cooler and a fan are housed and in which at least cool air can be blown into the storage room according to the present invention is provided when the cooler is not operated for the first time. The method further comprises the step of operating the cooler with the fan stopped for a second time shorter than the first time.

In the storage and the method of controlling the same according to the present invention, the cooler is stopped under a temperature condition that does not require the cooler,
If the state continues for the first time, for example, about one hour, the cooler is operated for a shorter time, for example, about five minutes to dehumidify. If only the dehumidification is taken into account, the fan may operate at the same time,
There is a high possibility that the storage room is excessively dehumidified, which further affects the temperature inside the storage room. For this reason, it is not suitable for a storage for storing an object to be stored, such as wine, which does not like the temperature change. On the other hand, it is possible to prevent excessive dehumidification and temperature change by keeping the operation time of the cooler extremely short, but a certain amount of time is required to reach a temperature at which the cooler can be dehumidified. In particular, when a cycle in which a refrigerant is circulated using an evaporator as a cooler is adopted, it is impossible to operate the evaporator for such a short time in consideration of the start and stop of the cycle. In some cases, it is better to avoid blowing cold air having a temperature different from the temperature in the storage room as much as possible, even for a short time.

On the other hand, in the present invention, only the cooler is operated, and the fan is not operated, so that only the air-conditioning room substantially separated from the storage room is cooled and dehumidified during the dehumidification. For this reason, it is possible to remove excess water without directly affecting the temperature and the stored items in the storage room, and store the stored items delicately with respect to temperature changes such as wine. can do. Further, it is possible to secure a certain operating time of the cooler for dehumidification, and it is possible to dehumidify the refrigerant cycle and the equipment constituting the refrigerant cycle without forcing.

Further, by employing the present invention, humidity control can be performed without constantly operating the cooler, so that running costs can be reduced. Further, since a humidifier is not required, the cost of the storage can be reduced. Therefore, according to the present invention, it is possible to provide a low-cost storage with high temperature and humidity control accuracy.

According to the present invention, it is possible to dehumidify the inside of the storage at an appropriate timing while suppressing the running cost. Therefore, in order to keep the humidity of the storage room relatively high, the humidity is controlled by evaporation such as a humidifying tray. Simple means can be installed. If a tray (drain tray or drain pan) that receives the drain of the cooler is installed in the air-conditioning room and the water level is formed in this tray, the water in the storage room can be recycled, and the water in the storage room can be recycled. Easy to stabilize humidity. Further, since the amount of drain discharged to the outside of the refrigerator can be reduced, the drain treatment can be simplified.

Further, when a heater is installed in the air-conditioning room for heating the room, the dehumidification can be performed at an appropriate timing by adopting the present invention. Therefore, it is necessary to operate the heater and the cooler simultaneously. Absent. Therefore, the storage chamber can be heated by operating the heater and the fan without operating the cooler, and dehumidification is performed at an appropriate timing even during the operation. Therefore, it is possible to provide a storage that can control the storage room in a predetermined temperature range and humidity range and that has low cost and low running cost.

[0015]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows a schematic configuration of a storage according to the present invention using a cross section. The storage 1 of this example is
It is a box-type storage that can store wine bottles at a predetermined temperature. The storage 1 has a heat-insulating housing 2, and a front surface 2 a is an openable / closable door 4. The upper part of the door 4 is provided with an area in which a glass 5 for cutting ultraviolet rays harmful to wine is fitted, so that the inside of the storage can be seen. Further, an operation panel 6 is disposed on the upper front surface of the housing 2 so that conditions such as the temperature inside the storage can be set and the state such as the temperature and humidity inside can be monitored.

The interior of the storage 1 is divided into three independent storage compartments 10, 11 and 12, each of which is insulated by two heat insulating partitions 3 arranged vertically. Each of the storage rooms 10, 11, and 12 accommodates a wine rack 60 of a sliding type.
A plurality of bottled wines (wine bottles) 61 can be stored in a horizontal position. Each of the storage rooms 10, 11 and 12 is provided with air 7 in each room.
A temperature adjustment mechanism 31 that can maintain the room temperature substantially constant by circulating 0 can be maintained at a temperature suitable for each purpose. For example, the room temperature of the upper storage room 10 and the middle storage room 11 can be selected from a set temperature in the range of 5 to 20 ° C., and the white wine or the red wine can be stored at a temperature suitable for drinking. In addition, the room temperature of the storage room 12 in the lower part of the room slightly wider is set for selection (preservation (aging)) in the range of 12 to 16 ° C.

The temperature adjusting mechanism 31 is provided in each storage room 1.
Each of the rooms or areas (air conditioning rooms in the present specification) 30a, 30b and 30c partitioned by a partition 21 behind 0, 11 and 12 is disposed, and a mechanism having the same configuration is provided for each storage room. It is prepared.
That is, the air conditioning rooms 30a, 30b and 30 of each storage room
c, evaporators (coolers) 33a, 33b and 3 for cooling the air 70 sucked from the lower suction port 35
3c and planar heaters 32a and 32 for heating the air 70.
b, and blowers 34a, 34b, and 34c that blow the temperature-regulated air 70 from the outlet 36 to the respective storage rooms are arranged in the respective air-conditioning rooms in order from the bottom. Further, a drain pan 40 that receives and collects the drain generated by each evaporator is disposed below each of the air conditioning rooms 30a, 30b, and 30c. The order of these arrangements is not necessarily limited to this example.

The drain collected in each drain pan (drain tray) 40 passes through a drain pipe 41 and is collected in an external drain pan 42 installed above the compressor 38. Then, the evaporating process is performed using heat of the compressor 38 and the like.

Each of the temperature adjusting mechanisms 31a, 31b and 31
c denotes the respective control circuits 50a, 50b and 50c
And are independently controlled. Further, as shown in FIG. 2, each of the temperature adjusting mechanisms 31a, 31b and 31
c cooler (cooler or evaporator) 33a, 3
3b and 33c are connected to a common compressor circuit arranged below the housing 2c and a common refrigerant circuit including a condenser 39, an expansion valve 37, etc. arranged behind the housing 2b. Therefore, a control circuit 51 for controlling a common mechanism such as the compressor 38 is also provided.

Each of the coolers 33a, 33b and 33c
Can be individually controlled by electromagnetic valves 36a, 36b and 36c provided upstream of the cooler by individual control circuits 50a, 50b and 50c.
Therefore, according to the temperature detected by the thermistor provided in each of the storage rooms 10, 11, and 12, the temperature control mechanisms 31a, 31b, and 31c provided in each of the air-conditioned rooms 30a, 30b, and 30c are independently provided. The air 70 is cooled by an evaporator. Also, the heater 32
a, 32b and 32c are also independent control circuits 50a,
0b and 50c. Fans 34a, 34b
And 34c. Therefore, the air 70 is heated or cooled in each of the air-conditioning rooms 30a, 30b, and 30c, and each cool air or warm air is supplied to the storage room via the fan. Thus, in the storage 1 of this example,
The room temperatures of the three storages 10, 11 and 12 are individually controlled, and the room temperature of each storage room can be maintained at a constant temperature according to the type and purpose of the stored wine throughout the four seasons.

Each of the storage compartments 10, 11 and 12 is further provided with a humidifying tray 45 provided inside the side wall 22 as a means for adjusting humidity.
The water inside 5 evaporates and can be humidified.
Further, the drain pans 40 of the air conditioning rooms 30a, 30b and 30c serve as humidifying means. That is, each drain pan 40 is provided with an evaporator 33a, 33b and 33c.
The condensed water discharged from the tank is not immediately discharged to the outside, and a water level is formed. For this reason, the air conditioning room 30
The air 70 sucked into a, 30b and 30c is humidified by passing over the drain pan 40. Therefore, the moisture is also humidified by the moisture evaporated from the drain pan 40, and as a result, the humidity in the storage room is increased. In many cases, during the period from the start of operation of the storage 1 to the accumulation of the drain in the drain pan 40, for example, about several days to several tens of days, each storage is performed by the moisture evaporated from the evaporation tray 45 installed on the side wall. The humidity of the chambers 10, 11 and 12 is maintained. Thereafter, when a water level is formed in the drain pan 40, the dehumidification by the cooling operation and the humidification by the moisture evaporating from the drain pan 40 are balanced, and the humidity in the storage chamber is almost in a steady state.

FIGS. 3 to 5 show control circuits 50a and 50a.
Among the controls performed by b, 50c and 51, an outline of control relating to temperature and humidity is shown by a flowchart. First, as shown in FIG.
0a, 50b, and 50c respectively detect the temperatures of the respective rooms 10, 11, and 12, and according to the results, evaporators 33a, 31b of the respective temperature adjustment mechanisms 31a, 31b, and 31c.
33b and 33c, heaters 32a, 32b and 32
A temperature control operation 100 for turning on and off c is performed, and an auxiliary control operation 110 for controlling a fan and the like is performed accordingly.
Further, the common control circuit 51 controls the temperature adjustment mechanisms 31
A common operation for controlling a common compressor or the like is performed according to the states of a, 31b and 31c.

The temperature control operation 100 performed by each of the control circuits 50a, 50b and 50c is common, and its outline is shown in FIG. In the following, the storage room 10
This will be described with reference to the control of FIG. In the temperature control operation, a temperature difference Δt between the room temperature and the set temperature is detected, and based on the result, the electromagnetic valve 36a is turned on and off to start or stop the evaporator 33a. In step 101, if the temperature difference Δt is equal to or greater than T0, the electromagnetic valve is turned on in step 102 to activate the evaporator 33a, thereby cooling the room 10. Correspondingly, at step 105, the temperature difference Δt
If T becomes equal to or less than T2, the electromagnetic valve is turned off in step 106 to stop the evaporator 33a, and the cooling of the room 10 is stopped.

On the other hand, at step 107, the temperature difference Δt is T3
If not, the heater 32a is turned on in step 108 to start heating. Correspondingly, step 103
If the temperature difference Δt is equal to or greater than T1, the heater 32a is turned off in step 104 to stop heating. Control circuit 5 of this example
At 0, the set temperature T0 at which the evaporator 33a is turned on is set higher than the set temperature T1 at which the heater 32a is turned off. The set temperature T at which the heater 32a is turned on is set.
3 is set lower than the set temperature T2 at which the evaporator 33a is turned off. For this reason, the heater 32a and the evaporator 33a are not turned on at the same time, and the temperature is controlled using either one of the devices, and both are stopped in the temperature range where the temperature control by the evaporator or the heater is not necessary. By doing so, power consumption is reduced.

In the temperature control step 100, the evaporator 3
When the heater 3a or the heater 32a is operated or stopped, the accompanying control is performed in the subsequent auxiliary control step 110. It is shown in FIG. First, step 1
When the frost is detected in step 11, the electromagnetic valve 36a is turned off in step 112, and the evaporator 33a is stopped. This waits for the frost to melt.

If the solenoid valve or the heater is turned on in step 113, that is, if the evaporator 33a or the heater 32a is in operation, step 114
To turn on the fan motor and drive the fan 34a. As a result, cool air or warm air flows from the air conditioning room 30a to the storage room 1
0, and the temperature of the storage room 10 is controlled. On the other hand, if both the solenoid valve and the heater are off, it is confirmed in step 115 that a predetermined time has elapsed since the turning off, and if the predetermined time has elapsed, the fan motor is turned off in step 116. And stop the fan. After the evaporator 33a is turned off, it is desirable that the fan 34a be continuously operated for an appropriate time of about several minutes so that the refrigerant does not stay inside the evaporator 33a. That is, in the system of this example, the condenser 39 and the compressor 38 are common, and the evaporator is stopped by stopping the supply of the refrigerant by the solenoid valve. Therefore, it is desirable to equalize the pressure inside the evaporator, and as a measure for this, the fan is continuously driven for an appropriate time. Immediately after the heater 32a is stopped, the heater 32a is in a high temperature state. Therefore, when the fan 34a is suddenly stopped, the heater 32a is overheated. Therefore, the fan is stopped after being driven for an appropriate time of about several minutes to reach an appropriate temperature at which no damage is caused.

Stopping the fan 34a at step 116 has several additional benefits. First,
Power consumption can be saved by stopping the fan 34a. Further, noise caused by the fan 34a can be stopped. Furthermore, if the fan 34a is continuously rotated, the condensed water on the evaporator 33a is re-evaporated and supplied to the storage room 10 as moisture, and the humidity in the storage room becomes too high. A drain pan 40 is provided in the air-conditioning room 30a, and performs a function of humidifying. However, when the fan 34a is continuously driven, moisture from the drain pan 40 is not dehumidified by the evaporator 33a. It is supplied to the storage room. On the other hand, these problems can be avoided by stopping the fan 34a after the equalizing process of the evaporator 33a is completed.

FIG. 6 shows a change in humidity of the storage room 10. As shown by the broken line 81, the relative humidity in the room where the fan is continuously driven reaches 90% or more, while the relative humidity in the room is stopped by stopping the fan as shown by the solid line 81 to store the wine bottle. About 85% or less suitable for

In the auxiliary control of this embodiment, it is determined in step 117 that the indoor temperature difference Δt is less than the set temperature T5. If the temperature difference is equal to or less than the set temperature, the rotational speed of the fan motor is reduced in step 118. Conversely, when the temperature is equal to or higher than the set temperature, the rotational speed of the fan motor is increased in step 119. By controlling the rotational speed of the fan 34a stepwise in this way, it is possible to prevent the fan noise from becoming unnecessarily large, and on the other hand, to cope with a situation in which the temperature needs to be rapidly controlled. Further, when the rotation speed of the fan can be reduced, the power consumption can be reduced by lowering the rotation speed.

Further, in step 120, the state where the solenoid valve is off, that is, the evaporator 3 which is a cooler
It is determined that 3a has been in the OFF state continuously for one hour or more. If it has been off for more than one hour, the solenoid valve 36a is turned on for 5 minutes in step 121, and the evaporator 33a is turned on. However, this step 121 and the rotation of the fan 34a are not linked, and the fan motor does not start even if the evaporator 33a is started. Further, in this step 121, the heater 3
When the fan 34a is operating in conjunction with 2a, the fan 34a is stopped and the solenoid valve 36a is turned on. By operating the evaporator 33a for a short time with the fan 34a turned off, the inside of the air conditioning room 30a is dehumidified. On the other hand, the cool air cooled by the evaporator 33a is not blown out to the storage room 10. On the other hand, the dehumidified air in the air conditioning room 30a is supplied to the evaporator 3
If the heater 32a is not restarted after the stop of 3a, the heater 32a gradually spreads into the storage room 10. On the other hand, the heater 32
When “a” is restarted, it is supplied to the storage room 10 by the fan 34a as warm air heated by the heater 32a. By temporarily dehumidifying the air in the air-conditioning room 30a as described above, it is possible to dehumidify the air in the storage room 10 without greatly affecting the temperature.

Further, an appropriate time is required until the temperature of the evaporator 33a decreases to a level at which dehumidification can be performed.
For this reason, it is impossible to operate the evaporator 33a for a short time that does not affect the temperature of the storage 10. On the other hand, when the evaporator 33a is started only for dehumidification, the fan 34a is stopped to substantially isolate the evaporator 33a from the air conditioning room 30a. Therefore, even if the evaporator 33a is activated for an appropriate time, there is no effect on the storage room 10.

FIG. 7 shows the effect of the dehumidifying operation performed in steps 120 and 121. As indicated by the dotted line 83, if the dehumidifying operation is not performed, the humidity in the room 10 gradually increases, but the relative humidity exceeds 90%.
This is because the water released from the surface of the wine bottle 61 or the like, which is stored, and the water evaporated from the humidifying tray 45 installed in the storage room 10 are the evaporator 33a.
This is considered to be caused by remaining without being dehumidified. Furthermore, since the fan 34a also rotates when the heater 32a is on, the moisture evaporating from the drain tray 40 of the air-conditioning room 30a also increases the humidity.

On the other hand, in the storage 1 of this embodiment,
As shown by the solid line 84, by periodically moving the air porator (cooler or cooler) for a short period of time, it is possible to periodically dehumidify, and the relative humidity in the room is 85% or less suitable for storage of wine bottles and the like. Can be suppressed. In particular, in the storage 1 of this example, a drain tray 40 performing a humidifying function is provided in the air-conditioning room, and a humidifying tray 45 is provided in each room to prevent low humidity. For this reason, it is a configuration that tends to be on the high humidity side,
By employing the function and control method of the control circuit 50 described above, dehumidification can be performed at an appropriate timing. Therefore, regardless of the surrounding conditions, the relative humidity in the room can be maintained in a range of about 60 to 85% suitable for storing the wine bottle 61.

FIG. 8 is a graph showing some examples. As indicated by the broken lines 85 and 87, unless the above-described control, in particular, the dehumidification control in steps 120 and 121 and the control for stopping the fan in step 116 are performed, high humidity easily occurs when the ambient temperature is low. . On the other hand, as shown by the solid lines 86 and 88, by performing the control of the present example, the relative humidity can be reduced from 60 to 8 over a wide range.
Humidity suitable for storing about 5% of wine bottles can be maintained.

In the other storage rooms 11 and 12, the conditions in the room are controlled by the control circuits 50b and 50c in the same manner as described above. And each room 10, 11 and 1
Since the setting temperature of 2 can be set freely, it is necessary to set up a storage room for aging wine, a storage room for maintaining red wine at an easy-to-drink temperature, and a storage room for maintaining white wine at an easy-to-drink temperature. Can be. Further, as shown in FIG. 3, in the common control circuit 51, when one or more solenoid valves are turned on in Step 125, Step 1 is performed.
At 26, the compressor 38 is turned on to start the refrigerant cycle. When all solenoid valves are turned off, step 1
At 27, the compressor 38 is turned off to stop the refrigerant cycle, so that each of the temperature maintaining mechanisms 31a, 31b and 31c can exhibit a predetermined capacity, and the power consumption is reduced.

In the above description, the present invention has been described by taking a storage for storing wine bottles as an example, but the storage target (storage) is not necessarily limited to wine bottles.
Since moderate humidity can be accurately maintained with a simple configuration, and running costs can be reduced by suppressing power consumption, the present invention can be applied to refrigerators for vegetables and the like.

In this embodiment, the evaporator is activated periodically to dehumidify the air. However, it is also possible to provide a humidity sensor and perform the same process as described above when the humidity becomes high. is there.

Further, in the above description, a temperature maintaining mechanism employing an evaporator as a cooler has been described as an example. However, the present invention can be applied to a storage provided with a temperature maintaining mechanism using other means such as a Peltier element. Applicable. A Peltier device is convenient because it is possible to switch between cooling and heating by reversing the direction of the applied voltage. Furthermore, according to the control of the present example, it is not necessary to simultaneously operate the cooling device and the heating device, so that it is possible to control the temperature and humidity by one Peltier element, which is simpler and lower cost. A storage can be realized.

[0039]

As described above, the storage of the present invention is a storage provided with a cooler such as an evaporator for maintaining the temperature in the storage room, and stops the cooler when cooling is unnecessary. At the same time, the humidity in the storage room can be appropriately maintained by driving the cooler spotwise for dehumidification. And when driving the cooler for dehumidification, by stopping the fan that supplies cool air, the inside of the partition where the cooler is installed is separated from the storage room, and the temperature of the storage room is not affected as much as possible. We are trying to dehumidify. Therefore, according to the storage and the control method of the present invention, dehumidification can be performed with a simple configuration without affecting the room temperature. For this reason, it is possible to provide a storage suitable for storing storage items, such as wine, which are desirably stored in an environment where there is little change in temperature and humidity.
