DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a refrigeration apparatus for refrigerated storage, and more particularly to a cereal refrigeration apparatus suitable for preserving cereals such as white rice and wheat at a low temperature.

[0002]

2. Description of the Related Art In recent years, in order to easily obtain fresh white rice even in the summer, households and farmers have been studying a cold-keeping rice bin apparatus as shown in FIG. The cold storage type rice bin device 90 shown in FIG. 3 has a vertically long housing 2, and a storage 20 for storing white rice is installed inside the housing 2. The storage 20 is surrounded by a heat insulating material 29, and the heat insulating material 29 performs heat insulation processing. A weighing device 4 for dispensing desired white rice from the storage 20 is installed below the storage 20, and below the weighing device 4, for taking out the white rice dispensed by the weighing device 4. Is provided. Above the storage 20, a heat absorbing unit 13a and a heat discharging unit 14
a is provided with a cooling device 10a. Cooling air can be supplied from the cooling device 10a to the interior of the storage 20 to cool the interior of the storage 20.
For this reason, the rice bin device 90 can construct an environment suitable for long-term storage of white rice inside the storage 20.

[0003]

The rice bin device 90 shown in FIG. 3 feeds in cool air from above and efficiently stores the rice.
Can be cooled, but the cooling device 10a is installed above the storage 20. To put white rice in the storage 20, the cooling device 10a is removed, or an input port is provided on the side of the housing 2. It has to be provided separately, which is inconvenient for households and farmers. Further, since the storage 20 and the cooling devices 10a are arranged in the vertical direction, the height of the rice bin device 90 becomes very large. Further, when dew condensation occurs in the heat absorbing unit 13a, the dew drops on the storage 20 and wets the white rice, which causes deterioration in the quality of the white rice.

Therefore, a Peltier device (Peltier cooling unit) which can form a simple cooling system which does not require a refrigerant and does not require a compressor, an evaporator, etc., is provided as a refrigeration device having a size which can be easily installed in a home or the like. A rice bin device that employs the used Peltier cooling device and further installs the Peltier cooling device on the side of the storage 20 is being studied. According to such a rice bin device, the height of the rice bin device can be kept low and the upper portion is free, so that a storage box into which white rice can be put from above can be adopted. Therefore, a rice bin device that is easy to use at home or the like can be realized. In addition, since the heat absorbing portion is provided on the side of the storage, the condensed drain can be collected without dripping into the storage.

[0005] Even when the storage box is closed, outside air enters when rice or the like is thrown in, and there is a leak from a joint of a sheet metal or the like, so that the amount of collected drain gradually increases. Therefore, if the collected dew water (drain) is not periodically drained, it will overflow from a collection device such as a drain tank, causing the floor on which the refrigeration device is installed to become wet.
Further, if the overflowed drain flows into the take-out container 5 or the like, the white rice is wet in the final stage of taking out the white rice from the rice bin device, and the quality of the white rice stored in the refrigerator is deteriorated. In addition, a rice bin device of a type in which cool air is circulated not in the storage but around it to cool the storage from the surroundings and lower the temperature in the storage has been studied, but this type of rice bin device is also considered. Since the circulating layer of cold air cannot be completely sealed, the amount of drain gradually increases. For this reason, as described above, if the drain is not periodically drained, there arises a problem that the white rice gets wet when the drain is taken out.

Accordingly, an object of the present invention is to provide a refrigeration apparatus that can be used safely by ordinary users in ordinary households and farmhouses without worrying about drain collection. It is another object of the present invention to provide a refrigeration apparatus for grain that does not wet the floor even if the drainage of the collected drain is forgotten, and does not wet the white rice due to leakage of the drain into the extraction container.

[0007]

As described above, the use of a Peltier cooling device as a cooling device for a refrigeration device such as a small rice bin device that can be easily installed at home or the like has been studied. Since DC power is required to drive the Peltier cooling device, a power supply device for converting AC power to DC power is installed in the refrigerator. Since it is necessary to determine the arrangement of the cooling device in consideration of the heat radiation from the power supply device, the power supply device is installed on the same side as the heat exhaust portion of the Peltier cooling device, and both heat exhaust sides are oriented in the same direction. Like that.

Therefore, in the present invention, the drain generated in the heat absorbing portion is guided to the heat-dissipating side, and is evaporated using the heat radiation of the power supply device so that the drain can be discharged through the outside air circulating around the heat-dissipating side. I have to. Therefore, the drain generated in the heat absorbing section is continuously evaporated on the exhaust heat side,
It is not necessary to periodically drain the drain to the outside, and it is possible to prevent a problem such as drain overflow from the drain tank or the like.

[0009] That is, the refrigeration apparatus of the present invention has a storage that can store refrigerated items, and a Peltier cooling device installed beside the storage, and the Peltier cooling device is provided on the side of the storage. A heat absorbing section extending along the heat absorbing section and a heat discharging section disposed outside the heat absorbing section, wherein a power supply device for supplying power to the Peltier cooling device is disposed below the heat discharging section. cage, further, with installing the evaporation tray for evaporating drain between a power supply device and the exhaust heat unit, provided drain recovery device for guiding the drain occurring in the heat absorbing portion to the evaporation tray, of the evaporating tray Steam is sent to the exhaust heat section
It is to so that is exhausted to the outside after being more heated.

In the refrigerating apparatus of the present invention, since the heat absorbing portion where the drain is generated and the heat discharging side where the heat discharging portion is installed are arranged close to each other, the distance from the portion where the drain is collected to the evaporation tray is reduced. Short and easy to collect drain. further,
Since clogging of piping could be lower for generating high reliability can be provided drain recovery system. In addition, since the drain recovery device can be simply configured, it is suitable for reducing the price of the refrigeration device.

The refrigeration apparatus of the present invention is a refrigeration apparatus for cereals for storing cereals such as white rice and wheat, which is provided with a cereal input port above the storage and a cereal discharge port below the storage port. Also applicable to: Since the refrigeration apparatus of the present invention can self-process the drain using the heat of the power supply unit and the heat exhaust unit , the user does not need to periodically drain the drain, and the user does not need to worry about the generation of drain at all. There is no.
For this reason, it is possible to realize a grain refrigeration apparatus that is easy to use in ordinary households, farmers, and the like. In addition, since the drain is evaporated, the drain does not overflow from the drain tank or the like, and the drain can be prevented from leaking into the inside of the apparatus and impairing the quality of the white rice, and there is no fear that the floor surface is wetted by the drain during refrigeration. . Therefore, the inside of the storage can be maintained in an appropriate humidity state, and a refrigeration unit for cereals that can store cereals such as white rice in an appropriate environment can be easily used.

As described above, according to the present invention, since the drain generated in the heat absorbing portion does not leak into the inside of the apparatus, the grain take-out container can be installed below the storage, and the more convenient grain refrigeration can be used. The device can be realized. In addition, the grain can be put into the storage from above and the grain can be paid out from below the storage, so that a very easy-to-use grain refrigerating apparatus can be realized in this respect as well.

In addition, when storing grains, the inlet is not frequently opened and closed, so that the amount of drain generated in the heat absorbing portion is small, and the drain collected by heat radiation of the power supply device can be reliably evaporated. Thus, a highly reliable grain refrigeration apparatus can be realized.

In particular, in the refrigerating apparatus of the present invention, the vapor of the drain treated in the evaporating tray is also guided to the exhaust heat section, so that the vapor is heated in the exhaust heat section and exhausted to the outside in a low humidity state. Is done. For this reason, even if the air containing the drain is exhausted to the outside, dew condensation does not occur on the outer wall of the device or in the vicinity thereof, and a grain refrigerating device that can be used safely at home or the like can be realized.

Further, in the present invention, the provision of a cooling fan can enhance the exhaust heat effect of the Peltier cooling device and increase the amount of circulating air, so that an environment suitable for evaporating the drain is provided. Can be constructed. Thus, it is possible to reduce the power consumed for storing the refrigerated material, and to provide a refrigeration apparatus that is easy to use in homes and the like with low running costs.

An input port 21 capable of being input to 0 appears, from which white rice can be input into the storage 20. The storage case 20 of this example is surrounded by a metal plate having excellent thermal conductivity, and has a hollow space having a rectangular cross section and extending vertically. The lower part of the storage 20 is a tapered dispensing part 22 having a rectangular section and a gradually narrowing space. The weighing device 4 can be operated from the front panel 2 a of the housing 2, and can discharge desired white rice from the storage 20 by an external operation. A take-out container 5 is detachably provided below the weighing device 4 for taking out the discharged white rice to the outside. For this reason,
The user can easily obtain a desired amount of white rice without opening the lid 3 or the like. As described above, the rice bin device 1 of the present example can put in white rice from above and can take out white rice stored in the storage 20 from below. Has become.

In the rice bin device 1 of the present embodiment, the periphery of the storage 20 is surrounded by a heat insulating wall 29 at a predetermined interval, and the space between the storage 20 and the heat insulating wall 29 is a Peltier cooling device 1.
0 forms a layer 28 through which the air cooled is circulated. Accordingly, the air cooled by the Peltier cooling device 10 serves as a medium to gradually cool the storage 20 from the entire surroundings, thereby absorbing the heat of the storage 20 and the white rice put into the storage. Spacers 29a are inserted at predetermined intervals between the storage 20 and the heat insulating wall 29, and the spacers 29a allow the air circulating layer 2 to be inserted.
8 are secured.

The Peltier cooling device 10 for cooling the air in the circulating layer 28 is provided on the side of the rear panel 2 b of the housing 2 with respect to the storage 20.

Is provided with a circulation fan 15 for increasing the circulation efficiency of the cool air in the circulation layer 28 cooled by the Peltier cooling device 10.
The cool air circulates uniformly throughout the circulation layer 28. Thereby, since the storage 20 can be cooled in a more uniform state from the entire periphery, the whole white rice put in the storage 20 can be cooled in a uniform state, and the whole white rice can be stored with good freshness. it can.

A power supply 30 for supplying electric power to the Peltier cooling device 10 is provided below the heat sink 14.

The power supply device 30 converts home AC power into DC power using an AC / DC converter or the like so that the Peltier cooling device 10 can be operated with a home AC power source, and converts the DC power to the Peltier cooling unit 11. It has a mechanism for supplying. The converted DC power is supplied not only to the Peltier cooling unit 11 but also to the circulation fan 15.
And a cooling fan 35 described later. As described above, in this example, in consideration of heat radiation from the power supply device 10, the power supply device 10 and the heat-dissipation-side heat sink 14 are arranged vertically so that ventilation is facilitated.

In the rice bin device 1 of this embodiment, a collecting tray 33 for receiving the drain 30 a generated by the heat sink 13 is provided below the heat sink 13. Although the circulating layer 28 is shielded from the outside by the heat insulating wall 29 and the like, outside air enters the circulating layer 28 through a gap when white rice is charged. For this reason, there is a possibility that dew condensation may occur on the heat sink 13, and the drain 30 a generated by the collection tray 33 can be reliably collected. Therefore, the generated drain 30a travels along the wall of the storage 20, and the storage 2
It can be prevented from flowing into the weighing device 4 or the take-out container 5 installed below the zero or leaking to the floor.

The collection tray 33 includes an evaporation tray 32 provided between the heat-dissipating heat sink 14 and the power supply 30.

Therefore, it is not necessary to periodically drain the collected drain 30a to the outside, and it is possible to avoid a problem that the drain 30a leaks from the collection tray 33 or the evaporation tray 32. For this reason, it is possible to prevent the drain 30a from leaking into the inside of the apparatus and impairing the quality of the white rice, and there is no fear of wetting the floor surface. Therefore, it is possible to easily use a rice bin device capable of storing white rice in an appropriate environment.
In addition, in the rice bin device 1 of the present embodiment, the amount of the drain 30 a generated in the heat absorbing heat sink 13 is small, and the drain 30 a collected by the heat radiation of the power supply device 30 is reduced in consideration of the frequent white rice being not charged. Evaporation can be performed reliably. For this reason, a highly reliable rice bin device that can be used without worrying about drain recovery can be provided. Further, the drain 30 treated by the evaporation tray 32
The steam a is guided to the heat-dissipating heat sink 14 by the cooling fan 35, where it is heated and exhausted to the outside with little humidity. For this reason, even if the air containing the drain is discharged to the outside, the dew condensation does not occur on the outer wall of the device or in the vicinity thereof, and a rice bin device that can be used safely at home or the like can be realized.

In the rice bin device 1 of the present embodiment, the collecting tray 3 for the drain 30a generated by the heat sink 13 on the heat absorbing side is used.
3 and the evaporation tray 32 are arranged close to each other, and the distance between these trays 32 and 33 is short. For this reason, the collected drain 30a can be easily and reliably guided to the evaporation tray 32. In other words, a highly reliable drain recovery system that has a low risk of clogging or the like of the drain pipe 31 can be configured with a simple configuration, so that an inexpensive rice bin that can be easily and safely used at home or the like. Equipment can be provided.

Further, the rice bin device 1 of the present embodiment comprises a storage 2
Since the white rice can be put in from above and the white rice can be paid out from below the storage 20, the usability is very good also from this point. In addition, in the rice bin device 1 of the present example, since the detachable take-out container 5 is installed below the storage 20, when obtaining the white rice put into the storage 20,
