Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] The present invention relates to a wine storage.

[0002]

2. Description of the Related Art In recent years, the number of people who drink wine has increased,
Accompanying this, wines are stored at home, and the demand for home wine storage is increasing.

[0003] For storage of wine, the temperature is from 11 ° C to 17 ° C.
° C, the relative humidity RH is kept at a constant condition of 65% to 85%,
It is said that it is best to ensure low vibration.However, conventional wine storage uses a compressor system like a refrigerator, and a humidification system with a puddle inside the storage room. Some are.

[0004]

However, in a conventional compressor-type wine storage, the compressor is controlled to be on and off to keep the interior of the warehouse at a constant temperature. Not only can it be avoided that the temperature rises to 0.8 ° C or more, but also the temperature difference of the cooling air blown out into the storage chamber becomes 10 ° C or more, so that the temperature change of the wine bottle affects the quality of wine depending on the place. There was a problem that it became larger.

[0005] Further, the relative humidity RH of the interior chamber greatly changes from 45% (when the compressor is turned on) to 72% (when the compressor is turned off) to a low humidity side, thereby promoting the drying of the cork stopper. In the case of the humidification method,
% To 97%, and there is a problem that the humidity may be close to 100% and mold may be generated on the label.

[0006] Further, large vibrations are generated as the compressor is turned on and off.
Vibration having an amplitude of about 8 μm is generated, which has a problem of adversely affecting the storage of wine.

The present invention has been made in view of the above-mentioned conventional problems, and provides a wine storage that can maintain the temperature of the interior chamber at a predetermined temperature with a small temperature difference, can maintain the humidity in a desired range, and has less vibration. It is intended to be.

[0008]

In a wine storage according to the present invention, a cooling means using a thermoelectric member is disposed in an interior room surrounded by a heat insulating wall, and a voltage applied to the thermoelectric member during a normal operation is reduced. The thermoelectric member is operated by the control, and the temperature of the interior chamber becomes 11
The temperature is controlled so as to be a predetermined temperature set within a temperature range of from 17 ° C. to 17 ° C. Since a cooling means using a thermoelectric member such as a Peltier element is used, as in the case of a compressor, Vibration does not occur during operation, and temperature control is performed by operating the cooling means by voltage control instead of on / off control.
The temperature can be maintained at a predetermined set temperature within the above-mentioned temperature range suitable for storing wine in a state where the temperature difference is small, about 2 ° C, and the wine can be stored in a good state.

In addition, the cooling means exchanges heat with the thermoelectric member, a cooler for circulating a brine for exchanging heat with the cooling side of the thermoelectric member and exchanging heat with the air circulating in the internal chamber, and a radiating side of the thermoelectric member. If a configuration is provided that includes a radiator that circulates brine and exchanges heat with the outside air, air whose temperature is controlled by the cooler is circulated to the inside chamber of the refrigerator.
By controlling the temperature in the range of about 3 ° C., the temperature difference of the circulating air discharged to the interior chamber becomes 1 ° C., and the temperature difference of the interior chamber is ± 0.2.
The temperature can be controlled to about 2 ° C., and the entire interior chamber can be uniformly and accurately maintained at a predetermined set temperature.

Further, the temperature of the cooler is set at 3 ° C. below the set temperature.
By controlling the temperature of the interior chamber to a set temperature by controlling the temperature to a lower temperature of about 7 ° C., and setting the relative humidity RH of the interior chamber to approximately 65% to 85%, the thermoelectric power is generated during the steady operation. The appropriate humidity is automatically maintained only by controlling the temperature by the member, and the temperature and the humidity can be easily and inexpensively maintained in the desired ranges.

If a means for changing the set temperature with an operation switch is provided, a desired temperature can be easily set according to the user's preference and environmental conditions.

Further, if the rotation speed of the blower fan for circulating the air in the interior chamber is fixed and the temperature is controlled only by controlling the voltage applied to the thermoelectric member, only the voltage control is required. And it becomes cheap. On the other hand, if the temperature is controlled by controlling both the rotation speed of the blower fan that circulates air in the storage chamber and the voltage applied to the thermoelectric member,
Although the control configuration becomes complicated, more precise temperature control can be performed according to use conditions and the like.

Further, if a heating means and a humidifying means are provided separately from the cooling means and the heating means and the humidifying means are operated in an unsteady operation state in which the outside air temperature is lower than a set temperature, the outside air temperature is reduced. Even in an unsteady operation state lower than the set temperature, the interior chamber can be kept at a predetermined temperature and humidity.

If the heating means is constituted by a heater and the heater is turned on and off in accordance with the detected temperature of the internal chamber, the temperature can be controlled with a simple structure. The evaporating dish configured to expose the water surface to the interior chamber and a water tank that supplies water at a certain level to the evaporating dish can be humidified with a simple structure and naturally humidified. There is little risk of humidification.

Further, in an unsteady operation state in which the outside air temperature is lower than the set temperature, the polarity of the voltage applied to the thermoelectric member may be inverted, and the applied voltage may be controlled so as to reach the set temperature. No additional heating means is required.

Further, a humidity sensor is provided in the interior chamber, and when the interior chamber has a predetermined humidity or more, the cooling means is controlled to a temperature lower than a set temperature to dehumidify and control to a predetermined humidity. In addition, over-humidification in the storage room can be reliably prevented.

Further, a humidity sensor and a humidifying means are provided in the chamber, and the humidifying means is operated when the temperature of the chamber becomes lower than a predetermined humidity. By performing the control, the humidity in the storage room can be more reliably controlled.

Further, if the cooling means is controlled at a temperature lower than the set temperature for a predetermined period for a predetermined period of time so as to dehumidify, the interior chamber is easily maintained at a desired humidity when it tends to over-humidify. be able to.

Also, just by controlling the temperature of the cooler 25 as described above, the appropriate humidity is automatically maintained, the temperature and humidity can be easily and inexpensively maintained in a desired range, and the cork stopper of the wine bottle can be appropriately adjusted. The state can be maintained, and there is no occurrence of mold on the label due to excessive humidification.

Further, instead of directly cooling the internal chamber 3 by the thermoelectric element 22, brine is circulated between the thermoelectric heat exchange block 21 having the thermoelectric element 22 and the cooler 25, and the cooler 25 uses the brine. Heat exchange with the air circulating in the chamber 3
Since the heat is exchanged with the outside air in the radiator 30 in which the brine is circulated to radiate heat, and the air whose temperature is controlled by the cooler 25 is circulated to the inside chamber 3, for example, the temperature of the cooler 25 By controlling the difference within the range of about 0.3 ° C., the temperature difference of the circulating air discharged from the blower fan 15 to the interior chamber 3 becomes 1 ° C., and the entire interior chamber 3 is uniformly and ± as described above.

Thus, even in the unsteady operation state in which the outside air temperature is lower than the set temperature, the interior room 3 is maintained at the predetermined temperature and humidity with a simple configuration.

When the heating control by the heater 40 is performed as described above, the inside chamber 3 generally tends to be over-humidified and tends to be over-humidified. ), The supply voltage to the thermoelectric element 22 may be increased for a predetermined time to forcibly lower the temperature of the cooler 25, and the inside chamber 3 may be controlled to be lower than the set temperature. The desired humidity can be easily maintained by dehumidifying the chamber 3.

However, the temperature control may be performed by controlling both the rotation speed of the blower fan 15 and the voltage applied to the thermoelectric element 22, and the control configuration becomes complicated, but more precise temperature control is performed according to the use conditions and the like. Becomes possible.

In the above-described embodiment, an example has been described in which the heater 40 is turned on and off to control the temperature to a predetermined temperature in the unsteady operation state. However, the polarity of the voltage applied to the thermoelectric element 22 is inverted to control the applied voltage. The temperature may be controlled so as to reach the set temperature, in which case no additional heating means is required.

Further, by providing the in-compartment humidity sensor 42 in the in-compartment room 3, when the in-compartment room 3 becomes higher than a predetermined humidity, the thermoelectric element 22 is cooled to a temperature lower than a predetermined temperature specified by a set temperature. The dehumidification can be controlled so that the humidity is forcibly controlled to a predetermined humidity, so that excessive humidification of the interior chamber 3 can be reliably prevented.

Further, a humidifying means for forcibly humidifying the interior humidity sensor 42 with the interior humidity sensor 42 is provided in the interior chamber 3, and when the humidity in the interior chamber 3 becomes lower than a predetermined humidity, the humidifying means is operated to force humidification. If the humidifying means is stopped at a predetermined humidity and the temperature and humidity are controlled by the thermoelectric element 22 as described above, the humidity in the storage room can be more reliably controlled.
