Description

[0001] Apparatus for transporting and delivering agrifood [

BACKGROUND OF THE INVENTION 1. Field of the Invention [0002] The present invention relates to an agricultural food water delivery apparatus to which a thermoelectric element is applied.

In recent years, there has been a growing demand for freshly distributed meat, fish, shellfish, fresh vegetables and fruits at low temperatures. In particular, in order to keep food at a low temperature, refrigeration vehicles, cold storage warehouses for refrigeration / Boxes, etc., the industry related to such a cold chain system is also continuously growing. However, unlike the outline growth of the distribution industry, the cold chain system is still in the introduction phase, and is focused on show-cases, refrigerators, refrigerators or parcel delivery type ice packs, .

Among the objects of low-temperature distribution, agricultural products are most sensitive to temperature changes. In case of using ice boxes, there is a short period of time in which fresh produce can be delivered (indicating a reduction in transportation and delivery). In addition, there is a problem that excessive power is consumed to operate the freezing / refrigerating machine when the agricultural products are transported by using the cart having the freezing / refrigerator, and after the agricultural products are taken out from the freezing / There is a problem that the agricultural products are left at room temperature during the process of transferring to the facility and the quality of the products is deteriorated.

On the other hand, a technique of utilizing a thermoelectric element for refrigeration or freezing is known. Here, a thermoelectric element is a metal element composed of a p-type semiconductor and an n-type semiconductor, and refers to a device in which a direct current is passed to generate a heat dissipation and heat dissipation of peltier, which is one of the effects of thermoelectric conversion. Korean Patent Application Laid-Open No. 10-2007-0102189 (Hereinafter referred to as "prior art") discloses a refrigerator to which a thermoelectric element is applied.

Referring to the above-mentioned prior art, a case is inserted into a storage room of a refrigerator, and the case comprises an inner case and an outer case. A cooling space is formed between the inner case and the outer case, and the cooling material is accommodated in the cooling space. The cool air generated from the thermoelectric element is blown into the inner case by a fan. Since the cool air is discharged from the coolant even if it is put outdoors by removing the case, the contents can be kept fresh for a certain period of time . However, the thermoelectric element operates only when power is supplied from the refrigerator, and the thermoelectric element does not operate at all when the case is removed and placed outdoors. As a result, in a state in which the case is placed outdoors, this prior art functions only as far as the time limit in which the heat storage material can release the cold air, unlike the conventional ice box, and thereafter the function is deteriorated. In addition, when the commercial storage material developed up to now is used, the freshness of the contents can not be maintained for 20 hours in a state where the case is separated from the prior art and placed on the outdoors.

SUMMARY OF THE INVENTION It is an object of the present invention to provide an agro food delivery apparatus with improved structure to prevent cold weather from occurring in agro-food products due to rapid temperature changes.

Further, it is an object of the present invention to provide an agri-food delivery apparatus with improved structure to maintain freshness of agri-food for a long time.

According to another aspect of the present invention, there is provided an apparatus for delivering foodstuffs, comprising: a storage and transport vessel having a storage space capable of accommodating agricultural products; A refrigerant tube, and a thermoelectric element having a heat absorbing portion capable of absorbing heat from the refrigerant tube to adjust the temperature of the refrigerant, and a heat generating portion capable of discharging the heat absorbed through the heat absorbing portion to the outside.

Preferably, the apparatus further comprises a phase change material pack disposed between the refrigerant tube and the storage space and capable of controlling the temperature of the storage space by filling the phase change material capable of storing heat of latent heat.

Preferably, the air conditioner further comprises a circulation fan installed at one side of the storage space and capable of circulating air in the storage space.

Preferably, the refrigerant tube has a first line disposed along the bottom surface of the storage space, and a second line connected to the heat absorbing portion of the thermoelectric element.

Preferably, the first line is arranged in a zigzag.

Preferably, it further comprises a battery capable of supplying power to the thermoelectric element.

The apparatus for delivering agricultural products according to the present invention has the following effects.

First, it is possible to prevent rapid change in the temperature of the storage space in which the agricultural products are housed, thereby preventing cold weather from occurring in the agricultural products.

Second, even when the power source is shut off, the freshness of the agricultural product can be preserved by keeping the temperature of the storage space at the target temperature for a predetermined time.

The storage and transportation container 10 may have a storage space 10a in which the agricultural products can be accommodated, and a lid 12 capable of opening and closing the storage space 10a. The material of the storage and transportation container 10 and the lid 12 is not particularly limited, and may be formed of, for example, a material having excellent storability or other heat insulation performance.

The refrigerant pipe 20 can regulate the temperature of the storage space 10a while circulating the refrigerant along the path and can have the first line 22, the second line 24, the third line 26, . The first line 22 is disposed along the bottom surface of the storage and transport vessel 10 and the second line 24 can be connected to the heat absorbing portion 92 of the thermoelectric element 90 to be described later, 26 may connect the first line 22 and the second line 24 to each other.

1 to 3, the refrigerant pipe 20 provides a circulation path of the refrigerant, and may be divided into a first line 22 to a third line 26 depending on the arrangement position.

The first line 22 is a line passing through the storage transportation vessel 10 and can be disposed along the bottom surface of the storage space 10a. The method of disposing the first line 22 is not particularly limited. For example, as shown in FIG. 2, the first line 22 is arranged in a zigzag manner on the bottom surface of the storage space 10a so that the surface area is increased .

The second line 24 is a line passing through the cooling tower 50 and can be connected to the heat absorbing portion 92 of the thermoelectric element 90 to be described later. A pair of third lines 26 is provided and the inlet of the first line 22 between the storage and shipping container 10 and the cooling tower 50 is connected to the outlet of the second line 24 and the outlet of the first line 22 ) To the inlet of the second line 24, respectively.

Therefore, in the first line 22, heat can be exchanged between the air in the storage space 10a and the refrigerant in the first line 22, so that the temperature of the storage space 10a can be controlled. In the second line 24, the second line 24 is connected to the heat absorbing portion 92 of the thermoelectric element 90 and the refrigerant of the second line 24 and the heat absorbing portion 92 of the thermoelectric element 90 are connected to each other. The refrigerant whose temperature has risen through the first line 22 can be cooled. More detailed contents of the temperature control of the refrigerant and the storage space 10a will be described later.

On the other hand, the type of refrigerant that can be used is not particularly limited, and may include, for example, at least one of water and an antifreeze. When water and an antifreeze solution are mixed to prevent icing, the refrigerant may contain 50 vol% to 90 vol% water and 10 vol% to 50 vol% antifreeze. It is most preferable to mix 90 vol% of water and 10 vol% of antifreeze solution in consideration of the temperature maintaining property of the refrigerant, but it is not limited thereto.

The phase change material pack 30 is disposed between the refrigerant tube 20 and the storage space 10a and is capable of regulating the temperature of the storage space 10a by filling a phase change material capable of storing latent heat.

The phase change material that can be filled in the phase change material pack 30 is not particularly limited and may include, for example, at least one of C 14 H 30 and C 18 H 38 .

As the phase change material pack 30 is disposed, no heat is exchanged directly between the refrigerant in the first line 22 and the air in the storage space 10a, and indirectly through the phase change material pack 30 Heat exchange occurs. That is, the refrigerant in the first line 22 is heat-exchanged with the phase change material of the phase change material pack 30, whereby the cool air of the refrigerant can be transferred to the phase change material to be stored in the latent heat storage. In addition, the phase change material of the phase change material pack 30 is heat-exchanged with the air in the storage space 10a, so that the cool air of the phase change material is transferred to the air in the storage space 10a, Can be adjusted.

By indirectly transferring the cool air of the coolant to the air in the storage space 10a through the phase change material, even when the temperature of the coolant is abruptly changed, the temperature change of the storage space 10a due to the high heat capacity of the phase change material Gently. Therefore, it is possible to prevent cold weather from occurring in the agricultural products contained in the storage space 10a due to a rapid temperature change in the storage space 10a.

The circulation fan 40 is installed at one side of the storage space 10a and can circulate air in the storage space 10a.

1, the circulating fan 40 may be installed on the upper surface of the storage space 10a and may discharge air toward the phase change material pack 30 provided in the lower portion of the storage space 10a . Thus, the heat exchange between the phase change material and the air in the storage space 10a can be promoted. The air is circulated in the counterclockwise direction in the right area of the storage space 10a and the air circulates clockwise in the left area of the storage space 10a with the phase change material pack 30 as the center.

The cooling tower 50 is a cooling device for cooling the refrigerant whose temperature has been increased by heat exchange with the phase change material.

A heat absorbing portion 92 of the thermoelectric element 90 is provided in the heat absorbing chamber 52c and a heat generating portion 94 of the thermoelectric element 90, a suction fan 100, (110) or the like may be installed.

The storage tank 60 is installed inside the machine room 52b and stores the refrigerant returned after heat exchange with the phase change material. That is, since the outlet of the first line 22 and the inlet of the second line 24 are connected to each other by the third line 26, The heat-exchanged refrigerant may be stored in the storage tank 60 through the third line 26 and through the second line 24.

The pump 70 is installed inside the machine room 52b and can discharge the refrigerant stored in the storage tank 60 at a predetermined pressure after sucking the refrigerant.

The control panel (not shown) is installed outside the machine room 52b and operates a plurality of buttons provided on a control panel (not shown) to control the overall operation of the thermoelectric element 90, Driving can be controlled.

A battery (not shown) is installed inside the machine room 52b, and can supply electric power required for driving the thermoelectric element 90 or other devices for delivering the agrichemicals according to the present invention. The type of the battery (not shown) is not particularly limited, and a portable battery having a voltage of, for example, 12V may be used. Therefore, the agriculture product water delivering apparatus 1 according to the present invention can be driven using electric power supplied from a battery (not shown) without a separate external power supply.

The dehumidifying fan 80 is installed on one side of the machine room 52b and discharges the air in the machine room 52b to the outside and supplies the dehumidified air to the outside through the pump 70, It is possible to discharge the heat to the outside and to remove the moisture generated in the machine room 52b.

The thermoelectric element 90 may cool the refrigerant discharged from the pump 70, and may include a heat absorbing portion 92, a heat generating portion 94, and the like. The heat absorbing part 92 absorbs heat from the refrigerant pipe 20 to adjust the temperature of the refrigerant. The heat generating part 94 can discharge the heat absorbed through the heat absorbing part 92 to the outside.

As shown in Fig. 3, the heat absorbing portion 92 is provided in the heat absorbing chamber 52c and may have a plurality of heat absorbing portion fins 92a. The heat absorbing portion fins 92a may be formed protruding from the surface of the heat absorbing portion 92 at predetermined intervals so as to increase heat transfer efficiency. 3, the second line 24 may extend from the pump 70 and enter the heat absorbing chamber 52c through the heat insulating partition wall 52 to be connected to the heat absorbing portion fin 92a. However, the present invention is not limited thereto, and the second line 24 may be directly connected to the heat absorbing portion 92.

The heat generating portion 94 is provided in the heat generating chamber 52d and may have a plurality of heat generating portion fins 94a. The heat generating part fins 94a may be formed protruding from the surface of the heat generating part 94 at predetermined intervals so as to increase the heat transfer efficiency.

Heat exchange is performed between the heat absorbing portion 92 and the refrigerant through the second line 24 as the thermoelectric element 90 is provided. As a result, the heat absorbing portion 92 absorbs the heat of the refrigerant, And the heat generating portion 94 can receive the heat absorbed from the heat absorbing portion 92 from the heat absorbing portion 92 and discharge the heat absorbed from the heat absorbing portion 92 to the outside.

The temperature of the refrigerant can be lowered to a predetermined target temperature by adjusting the voltage applied to the thermoelectric element 90 because the thermoelectric element 90 has a property of changing the temperature according to the applied voltage. The settable target temperature is not particularly limited, and may be set between 0 [deg.] C and 10 [deg.] C, for example, depending on the type of the agro-food product accommodated in the storage space 10a.

3, the second line 24 extends from the heat absorbing portion fin 92a again and passes through the heat insulating partition wall 52 to enter the connecting chamber 52a. In the second line 24, The outlet and the inlet of the first line 22 may be connected to each other by the third line 26. Therefore, a circulation cycle of the refrigerant may be formed between the first line 22, the second line 24, and the third line 26 of the refrigerant pipe 20. As a result, the refrigerant discharged from the storage tank 60 and pressurized by the pump 70 at a predetermined pressure is cooled to the target temperature in the heat absorbing portion 92 and then transmitted to the phase change material pack 30, And may be introduced into the storage tank 60 again.

When the refrigerant is continuously circulated for a predetermined period of time by using the circulation structure of the refrigerant, the temperature of the phase change material pack 30 is adjusted to the target temperature by the cool air of the refrigerant, and the temperature of the storage space 10a is also changed And can be adjusted to the target temperature by the material pack 30. In addition, even when the driving of the pump 70 and the thermoelectric element 90 is stopped, the cold air that has been cooled in the phase change material from the phase change material pack 30 is released into the storage space 10a, The temperature of the space 10a can be maintained at the target temperature.

The suction fan 100 can suck air from the outside and supply the air to the heat generating portion 94 of the thermoelectric element 90. The exhaust fan 110 can blow air that has passed through the heat generating portion 94 of the thermoelectric element 90 It can be discharged to the outside.

3, the suction fan 100 is installed at one side of the heat generating chamber 52d so as to face the heat generating portion 94, and the discharge fan 110 is installed at the other side of the heat generating chamber 52d. Therefore, the suction fan 100 sucks outside the cooling tower 50 and supplies the sucked air to the heat generating unit 94. The exhausting fan 110 is supplied to the heat generating unit 94 to absorb heat from the heat generating unit 94 The air can be discharged to the outside of the cooling tower 50 again. As a result, heat absorbed from the refrigerant in the heat absorbing portion 92 and transferred to the heat generating portion 94 can be discharged to the outside of the cooling tower 50.
