Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rice bin device for storing rice.

[0002]

2. Description of the Related Art A rice bin apparatus that refrigerates rice so that it can be stored at a stable quality even in summer when grains such as brown rice and white rice are easily damaged is commercially available in farms and homes. One of such chilled rice bin devices is a cold storage type in which grains such as brown rice and white rice are stored in a rice bin (storage unit), and cool air is circulated around the storage unit by a cooling device to cool and store white rice in the storage unit. There is a rice bin device. In this rice bin device, a payout device provided with a measuring device is provided below the storage unit,
Underneath is a case that accepts the paid rice.

[0003]

This case is a part for taking in and out of a main body (housing) of a rice bin device in order to take out weighed white rice. Therefore, when sliding the case, an appropriate clearance is required between the housing and the case in advance so that the housing and the case do not rub. For this reason, even when the case is stored in the housing, outside air enters the inside of the case and the housing via the clearance. When outside air enters the inside, the temperature of the inside of the housing becomes low. Therefore, particularly when the temperature is high and humid in the rainy season or summer, dew condensation may occur in the case or the housing. For this reason, the white rice in the dispensing device may get wet, causing mold or the like. In addition, white rice may be dispensed and wet when the condensation occurs. Further, it may cause a malfunction of the weighing function of the dispensing device. Therefore, how to seal the case is an important issue.

[0004] In addition, such a cold-keeping rice bin device,
It has been considered that a rice milling device is mounted, and the amount of brown rice paid out at any time can be milled while being cooled and stored in a brown rice state in a storage unit. This makes it possible to eat fresher and more delicious rice even at home. However, when rice is polished in a rice bin device, the bran is scattered at that time, and the handling of the bran is troublesome. If the bran scatters in the housing, cleaning is difficult. In addition, if bran remains in the rice bin device (product) as it is, it may cause pests. Further, if the bran leaks out of the housing and scatters in the home, cleaning is more difficult and there is a problem in hygiene. Therefore, it has been considered that the rice polishing apparatus is stored in a case that can be pulled out. At this time, a sealing mechanism is important to prevent the bran from scattering. It is also important for the rice polishing apparatus to prevent the intrusion of high-temperature and high-humidity outside air.

[0005] In a configuration in which the case inserted into the storage space of the main unit of the rice bin device can be pulled forward, considering the sealing property between the case and the main unit, the clearance between the storage space and the case should be reduced. It is desirable that there be almost no state. In particular, considering that outside air enters the dispensing device and the case, and that the bran blown out from the rice milling device installed in the case does not go outside, the upper surface of the case and the storage space are considered. I want to make the clearance with the ceiling as small as possible.

However, if there is no clearance, the upper surface of the case and the ceiling rub against each other, so that the case cannot be easily inserted or removed. Even if the clearance is made as small as possible, the upper surface of the case and the ceiling rub against each other while the case is being inserted and removed, and the clearance gradually increases.

Therefore, it is necessary to seal, for example, the entire storage space in a portion other than the upper surface of the case and the storage space, but this complicates the configuration and increases the cost. Also, if the seal cannot be made between the upper surface of the case and the ceiling, the bran will scatter in the storage space.

Therefore, in the present invention, a grain refrigerating apparatus that can reliably seal the upper surface of a case from which grains are dispensed and the ceiling surface of a space for storing the grains, and can easily remove and insert the case. It is intended to provide.

[0009]

Therefore, according to the present invention, by being inclined with respect to the direction in which the ceiling of the storage space and the upper part of the case are pulled out, it is easy to provide a clearance without providing the case with the case stored. In the retracted state, the ceiling of the storage space and the top of the case come into contact and can be sealed.

That is, a grain refrigeration apparatus according to the present invention includes a storage unit capable of storing grains, a cooling device capable of cooling the grains in the storage unit, a dispensing device capable of dispensing the grains from below the storage unit, and a dispensing device. And a case provided with a receiving space capable of receiving the grain to be stored, wherein the case can be pulled out forward from a storage space in a main body of the grain refrigeration apparatus, and when the case is inserted into the storage space, an upper sealing surface of the case is provided. When the case and the sealing surface of the ceiling of the storage space are in contact with each other, the sealing surfaces of the case and the storage space are inclined with respect to the direction in which the case is pulled out.

In the grain refrigeration apparatus of the present invention, the sealing surfaces of the upper part of the case and the ceiling of the storage space are inclined so that the directions in which they are drawn out are higher, respectively.
The respective sealing surfaces come into contact when the case is placed in the storage space. Therefore, in the stored state, the receiving space can be sealed by the upper part of the case and the ceiling of the storage space. For this reason, invasion of outside air can be prevented, and dew condensation on the storage space and the dispensing device can be prevented.

[0012] Further, even when the grain mill is stored in the case and the grain is milled in the receiving space, the receiving space can be sealed by the upper part of the case and the ceiling of the storage space when the case is stored. Further, it is possible to prevent scattering outside the grain refrigerator.

On the other hand, when the case is pulled out forward, the sealing surface is inclined, so that there is little gap between the sealing surfaces and a gap is formed between the upper part of the case and the ceiling of the storage space. Therefore, the case can be pulled out smoothly.

Further, since the upper portion of the case and the ceiling of the storage space do not rub while the case is being pulled out, the sealing surface does not wear. Therefore, when the case is stored, the case can be efficiently sealed. in this way,
In the grain refrigerating device of the present invention, the upper surface of the case can be hermetically sealed only by inclining the storage space and the sealing surface of the case with respect to the drawing direction. Therefore, it is not necessary to adopt a complicated and expensive method for sealing the entire storage space, and it is possible to provide a grain refrigeration apparatus that is low in cost, has high sealing properties, and has no trouble due to condensation. Also, in the one with a built-in grain mill, the bran does not scatter,
It is possible to provide a grain refrigeration apparatus whose processing is easy.

[0015] In the case accommodating the grain milling device, a groove extending in a direction perpendicular to the pulling-out direction is provided on the lower side of the upper surface panel forming the sealing surface on the upper part of the case, so that the upper surface of the case can be kept. Even if the bran leaks out from the ceiling of the storage space, the bran can be collected in the groove. Therefore, the inside of the storage space can be kept more clean.

[0016]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows the appearance of a rice bin device 1 having a built-in rice milling device as a grain refrigeration device according to the present invention. FIG. 2 is a longitudinal sectional view showing a schematic configuration of the rice bin device 1. The rice bin device 1 has a housing 2 having a vertically long, substantially rectangular parallelepiped shape, and a lid 3 that can be opened and closed is installed above the housing 2. Inside the housing 2, brown rice 70
And a dispensing device 5 having a measuring device 7 for dispensing a desired amount of brown rice 70 from below the storage portion 4 and a rice polishing device 30 for polishing the dispensed brown rice 70. Are arranged in order from the top.

Below the housing 2 of the rice bin device 1 is a storage space 60 in which the box-shaped case 32 is stored so that it can be taken in and out from the front side. When the rice milling device 30 is stored inside the case 32 and the case 32 is slid forward and opened, the rice mill device 1
Can be slid forward. Figure 3
It is shown in

The case 32 of this embodiment has a substantially rectangular parallelepiped shape, and a holder (receiving space) 31 for mounting a cylindrical receiving container 36 for receiving brown rice 70 is provided substantially at the center thereof. . The rice milling device 30 configured in the rice bin device 1 of the present embodiment rotates the milled rice splash 41 inside the receiving container 36 to stir the brown rice 70 received in the receiving container 36 and mill rice in the receiving container 36. This is a so-called mixer-type rice milling device that separates rice into rice bran 71 and white rice 72. Thus, the rice polishing apparatus 30 of this example
Is stored in the case 32, and the brown rice 70 is polished in the receiving container 36 installed in the holder 31.

The structure of the rice bin device 1 of this embodiment will be further described with reference to FIGS. Rice bin device 1 of this example
The storage unit 4 is located above, and a heat insulating material 9 such as styrene foam is arranged around the storage unit 4 at a predetermined interval 11. The gap between the storage section 4 and the heat insulating material 9 forms a circulation section 11 in which the cooled air circulates around the storage section 4. For this reason, the Peltier cooling device 20 is arranged facing the rear panel 2 b of the housing 2 so that the heat absorbing portion 13 comes to the circulation portion 11.

The upper part of the storage part 4 is a quadrangle, but the lower part is a truncated pyramid shape which is thinned so as to be connected to the dispensing device 5. The upper portion of the rectangular parallelepiped is surrounded by the circulating portion 11, and the air (cool air) cooled by the Peltier cooling device 20 circulates, so that the brown rice 70 stored in the storing portion 4 is indirectly cooled. Is done. For this reason, brown rice 70
Is kept refrigerated without any unevenness and at an appropriate temperature.

Further, a circulation fan 16 for forcibly circulating cool air is installed near the heat absorbing section 13.
By making the temperature 1 uniform, the inside of the storage section 4 is further uniformly cooled. The Peltier cooling device 20 includes a Peltier unit 19
The heat-dissipating unit 14 is disposed facing the rear panel 2b on which the louver 25 is installed. This heat removal unit 14
Below this, a heat radiating fan 24 for promoting heat radiation from the heat discharging unit 14, a power supply device 18, and a drain pan 52 for collecting drain generated in the heat absorbing unit 13 are arranged in this order. The drain pan 52 is for evaporating the drain generated in the circulation unit 11 by using heat of the power supply device 18 or the like.
And a drain collection pipe 54.

In the rice bin device 1 of this embodiment, the cool air cooled by the Peltier cooling device 20 circulates in the circulation portion 11 and cools the brown rice 70 inside the storage portion 4 from the entire periphery through the side wall 4 a of the storage portion 4. can do. Therefore, the brown rice 70 inside the storage unit 4 is, for example, brown rice 70 of about 15 ° C. even in summer when the outside air reaches 30 ° C.
Temperature suitable for maintaining the quality of the product. Furthermore, since the cooling is indirectly performed through the partition wall 4a of the storage section 4, the humidity is appropriately maintained.

On the other hand, when a large amount of outside air enters when the brown rice 70 is supplied to the storage section 4, the storage section 4 is gradually cooled by the cool air in the circulation section 11 through the communication hole 50 provided above the storage section 4. Is dehumidified to the extent that no condensation forms inside.

Fresh brown rice 70 refrigerated in the storage unit 4
Is dispensed by the dispensing device 5 to the rice mill 30 below. The dispensing device 5 has a function as a measuring device that can measure a predetermined amount, and a user can dispens an appropriate amount of brown rice 70 necessary for one rice cooking to the rice polishing device 30.

In the rice bin device 1 of the present embodiment, when the case 32 accommodating the rice polishing device 30 is stored in the housing 2 of the rice bin device 1, the holder 31 is set under the dispensing device 5, and the holder 31 is set. The brown rice 70 dispensed from the dispensing apparatus 5 is received in the receiving container 36 placed in the container. The receiving container 36 is a bran receiving container 38 on the outside of which receives the bran 71, and white rice 72 polished on the inside thereof.
Rice basket 37 for receiving rice. The bran receiving container 38 and the milled rice basket 37 are set on the holder 31 in an overlapping state. Polished rice basket 37 is made of white rice 72
It is a metal basket with a mesh that does not spill out. For this reason, the polished rice splash 41 set together with the receiving container 36 rotates therein, and the brown rice 70 is rubbed in the polished rice basket 37 to be separated into bran 71 and white rice 72, and the bran 71 is discharged into the bran receiving container 38. Is done.

In the rice polishing apparatus 30 of the present embodiment, the shaft 42 for rotating and driving the rice polishing blade 41 projects from the bottom surface of the holder portion 31, penetrates the receiving container 36, and projects into the rice polishing basket 37. Is attached to the tip of the rice mill. The shaft 42 is rotatably driven by a motor 44 below the holder 31 via a pulley 45 and a belt 46. In this example, this motor 4
4. Driving mechanism 40 including pulley 45 and belt 46
Are also stored in the case 32. When the case 32 is pulled out, not only the receiving container 36 but also the drive mechanism 40 is pulled out. Further, the drive mechanism 40 of the present embodiment uses the pulley 45 and the belt 46 to make the shaft 42 a belt drive. Therefore, the motor 44 can be arranged side by side with the holder 31, and the case 32 can be made thinner, and the height of the rice bin device 1 can be made lower.

FIG. 4 is a perspective view showing the external appearance of a case 32 containing such a rice polishing apparatus. Further, FIG. 5 shows a state in which the case 32 is pulled out from the rice bin device 1 main body by a cross section close to the side surface of the case 32 different from FIG. The case 32 of this example has an upper surface formed of a plastic upper panel 33 except for a holder (receiving space) 31, and a side surface 35a and a rear surface 35b also formed of a plastic panel. Further, the front of the case 32 is an entire panel 32a which forms a part of the front surface of the housing 2. This entire panel 32
The user can pull out the case 32 forward A from the storage space 60 of the housing 2 with holding a. Bottom 3 of case 32
Part 2c is an opening 34 in consideration of heat radiation of the rice polishing apparatus 30 housed therein.

In the rice bin device 1, the upper surface 33 a of the upper panel 33 of the case 32 contacts the lower surface 62 a of the ceiling 62 of the storage space 60, and eliminates the gap between the upper panel 33 of the case 32 and the ceiling 62 of the storage space 60. Thus, the holder 31 can be hermetically sealed. Therefore,
Upper surface 33a of upper panel 33 and lower surface 62a of ceiling 62
Are the respective sealing surfaces. In this example,
These sealing surfaces 33a and 62a are inclined at the same angle with respect to the drawing direction, and the case 32 is stored in the storage space 60.
When the seal surface 33a
And 62a come into contact. Therefore, the holder portion 31 can be sealed just by inserting the case 32 into the storage space 60, and at the same time, the periphery of the dispensing device 5 can be sealed.

On the other hand, when the case 32 is pulled out to the front A, the sealing surface 62a of the ceiling 62 of the storage space 60 and the sealing surface 33a of the upper panel 33 are respectively inclined in the direction of the front A. Just withdraw
A gap (clearance) C is formed between the sealing surface 62a of the ceiling 62 of the storage space 60 and the sealing surface 33a of the upper panel 33 of the case 32. Therefore, case 32
Can be drawn out such that the upper panel 33a does not rub against the sealing surface 62a of the ceiling 62 of the storage space 60.
Therefore, the case 32 can be inserted and removed very lightly.

As described above, in the rice bin device 1 of this embodiment, when the case 32 is stored, there is no clearance between the case 32 and the storage space 60, and the holder 31
Can be sealed. On the other hand, even if there is no clearance in the state where the case 32 is stored, the case 32 can be pulled out smoothly.

Therefore, when the case 32 is stored in the case storage space 62, it is possible to prevent outside air from entering the dispensing device 5 and the holder 31 from around the case 32. Therefore, it is possible to prevent the dispensing device 5 or the holder 31 and the receiving container 36 therein from dew condensation due to the high-temperature and high-humidity outside air entering the atmosphere in the housing 2. For this reason, mold does not occur and the quality of rice does not deteriorate due to entering the dispensing device. In addition, the discharge failure of the measuring instrument can be prevented. Furthermore, since the dew condensation of the holder part 31 can be prevented,
The quality of the brown rice 70 and the white rice 72 that has been dispensed here does not deteriorate due to moisture attached to the rice.

When rice is polished in the receiving container 36, the holder 31 is sealed by the sealing surfaces 33a and 62a. Therefore, the bran 71 does not leak out of the storage space 60 or the housing 2. Of course, case 3
The inside of the case 2 is sealed by the upper panel 33 and the like, so that the bran 71 does not accumulate inside the case 32.
Therefore, by polishing rice in a state where the case 32 is stored in the storage space 60, it is possible to prevent the rice bran 71 from scattering outside the storage space 60 or the housing 2.
For this reason, it is desirable that the rice polishing apparatus 30 be driven only when the case 32 is stored in the storage space 60 by the control unit 48.

In the case 32 in which the rice polishing apparatus 30 is stored,
On the lower side of the upper surface panel 33 of the case 32, there is provided a groove 39 extending in a direction perpendicular to the drawing direction (front A). Even if the bran 71 leaks out between the upper panel 33 of the case 32 and the ceiling 62 of the storage space 60, the bran 71 can be collected in the groove 39 by the groove 39.
For this reason, the inside of the storage space 60 can be kept more clean.

On the other hand, the case 32 is of a so-called front-loading type in which the case 32 is smoothly pulled out forward (in the direction of arrow A), so that when the case 32 is pulled out, the receiving container 36 can be easily attached and detached. And the polished white rice 72 and bran 7
1 can be removed from the case 32.

As described above, in the rice bin device 1 of the present embodiment, the upper surface 35 of the case 32, the storage space 60, and the ceiling 62 are formed so as to be inclined and coincide with each other. Case 32 to body 1
Can be put in and out. At the same time, when the case 32 is stored in the storage space 60, the holder unit 31 is also substantially closed.

Therefore, despite the simple configuration in which the sealing surface is inclined, the inside of the case 32 and the dispensing device 5,
Even outside air can be prevented from entering. For this reason, it is possible to prevent the quality of brown rice and white rice from deteriorating due to condensation or the like. In addition, since the outside air can be shut off, there is an advantage that the cooling efficiency of the storage unit and the like can be improved. And since packing and a complicated seal structure are unnecessary, a rice bin device with a high degree of sealing can be realized at low cost.

Further, as described above, in the rice bin device 1 of this embodiment having a built-in rice milling device, the processing of bran is facilitated as described above.

In the above description, the rice bin device 1 having a rice polishing function is described as an example. However, the present invention is not limited to this, and it is a matter of course that the present invention can be applied to a cold-keeping rice bin device that stores white rice. In such a rice bin device 1,
What is necessary is just to accept the white rice dispensed from the dispensing device 5 by the case 32.

Further, in the rice bin device 1 of this embodiment, a Peltier cooling device 20 which does not require a refrigerant and does not require a compressor or an evaporator is used as a cooling device. Therefore, the configuration of the cooling device can be simplified, and the cooling device can be made compact. Therefore, it is possible to provide a rice bin device with a rice milling function that is easy to install at home and that is low in cost. Of course, a cooling device other than the Peltier method can be adopted as the cooling device 20, but the Peltier method is desirable in the above points.

[0040]

As described above, the grain refrigerating apparatus of the present invention stores the case by tilting the ceiling of the storage space and the upper part of the case so as to match the direction in which the case is pulled out. You can easily slide without any clearance in the state. Then, in the stored state, the ceiling of the storage space and the upper part of the case come into contact and can be sealed. Furthermore, in the stored state, the receiving space can be sealed by the upper part of the case and the ceiling of the storage space. For this reason, in spite of the simple configuration in which the sealing surface is inclined, the invasion of the outside air can be prevented, and the storage space and the dispensing device can be prevented from dew condensation. Therefore,
It is possible to prevent brown rice and white rice from deteriorating in quality due to condensation or the like. Further, since packing and a complicated sealing structure are not required, a grain refrigerating apparatus having a high degree of sealing can be realized at low cost.

Further, in the grain refrigerating apparatus having a rice milling function to which the present invention is applied, grains such as brown rice can always be stored in a good condition, and the necessary quantity can be easily milled when needed. For this reason, even at home, even more delicious and delicious rice can be eaten.
