Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a cooling container for canned soft drinks and the like that uses a Peltier element (electronic cooling element) and a cold storage material.

[Cost technology]

Conventionally, a refrigerated box has been proposed in which a pre-cooled cold storage material (cold insulation material) is placed inside an insulated box, and canned goods and the like are placed around it. However, in such a refrigerated box, it is necessary to cool the cold storage material in advance using an electric refrigerator or the like, and the handling is complicated. Also,
There is a limit to its ability to keep cold water when it is taken out for long periods of time, such as in a car.On the other hand, there are thermos containers and other containers for keeping drinking water warm, but these containers only have insulation properties. Because of this, the cold storage capacity was even worse than the above-mentioned refrigerator box.

[Purpose of the invention]

An object of the present invention is to provide a cooling container that can keep canned beverages such as juice and beer cold for a long period of time, especially for portable use.

[Disclosure of the invention]

The cooling container of the present invention includes a cylindrical body for accommodating a coolant provided with a cool storage material, a Peltier element for cooling the cold storage material is attached, and is removably fitted to the cylindrical body. The device includes a Peltier element support body in which the Peltier element is brought into close contact with the regenerator material.

That is, in this invention, the cylindrical body provided with the cold storage material and the Peltier element support body having the Peltier element are removably fitted together and can be separated from each other. The Peltier device support can be attached to the cylindrical body and the Peltier device can be used to cool and keep the temperature cool, whether the device is carried indoors or outdoors using a household power supply or car battery. Here, the Peltier element refers to a semiconductor element in which one pole (surface) becomes high in temperature and the other pole (surface) becomes low in temperature due to the Peltier effect when a direct current is applied.

An embodiment of the present invention will be described based on FIGS. 1 to 4. In Fig. 1, ■ is an inner cylinder that accommodates drinking water (chilled material) such as canned juice or beer.This inner cylinder 1 is made of plastic or the like and has a bottomed cylinder shape, and the upper outer periphery is It is screwed into the lid body 2 through a screw groove 1a provided on the surface. A heat insulating material 3 is attached to the inner surface of the lid body 2. On the other hand, a cooling cylinder 4 having the same bottomed cylindrical shape and concentrically covering the inner cylinder 1 is disposed outside the inner cylinder 1 . This cooling cylinder 4 is made of a material with excellent thermal conductivity such as aluminum. A cold storage material 5 is filled and sealed between the inner cylinder 1 and the cooling cylinder 4, thereby forming a cylinder 6 for storing a coolant such as the aforementioned canned drinking water.

An outer cylinder 7 is further arranged on the outer peripheral surface of the cooling cylinder 4. The outer cylinder 7 is formed in a cylindrical shape, and its upper edge is bent inward and is locked onto a flange part 1b protruding from the outer circumferential surface of the inner cylinder 1. Further, the bottom opening of the outer cylinder 7 has a threaded groove 7a on its inner peripheral surface.
A heat dissipating plate 8 is screwed onto this to close the bottom opening of the outer cylinder 7 to form a Peltier element support 13. moreover,
A heat insulating material 9 is interposed between the outer peripheral surface of the cooling cylinder 4 and the outer cylinder 7 to block heat exchange between the cylinder body 6 and the outside air.

The heat sink 8 has a Peltier element 10 attached to its inner surface,
A male connector 1) for supplying direct current to the Peltier element 10 is attached to the outer surface of the corresponding heat sink 8. The Peltier element 10 is attached with the heat generating surface 10a on the high temperature side in close contact with the heat sink 8, and with the heat sink 8 screwed onto the bottom of the outer tube 7, the cooling surface 10b on the opposite side is pressed against the bottom surface of the cooling tube 4. Do it like this. A large number of heat dissipating fins 12 are formed on the outer surface of the heat dissipating plate 8, so that the heat emitted from the heat generating surface 10a of the Peltier element 10 is quickly dissipated into the atmosphere.

FIG. 2 is a perspective view showing the cooling container of this embodiment,
A hanging bell (14) convenient for carrying is attached to the outermost outer cylinder 7. Further, 15 is a power cord, and a female connector 16 into which the male connector 1 of the heat sink 8 is inserted is attached at one end, and a plug 17 is provided at the other end. A converter 18 for converting alternating current into direct current is attached to this cord 15.

FIG. 3 shows the cooling container of this embodiment in an exploded state. Disassembly can be easily carried out by removing the heat sink 8 from the bottom of the outer cylinder 7, pulling the outer cylinder 7 above the cylinder 6, and then pulling out the heat insulating material 9 below the cylinder 6. As shown in FIG. 4, the cylindrical body 6 taken out in this manner has the inner cylinder 1 covered with the cold storage material 5 and the thermally conductive cooling cylinder 4, so the cylindrical body 6 is fitted with a Peltier element 10. Separately, the cooled material is placed in a household electric refrigerator or the like to sufficiently cool it, and then the heat insulating material 9° outer cylinder 7 and the heat radiating plate 8 are attached in the reverse order to form a cooling container. However, if power is not available when carrying the device, the bottom portion may be covered with a heat-insulating lid (not shown) instead of the heat sink 8.

The standard method of using this cooling container is to apply a direct current to the Peltier element 10 with the heat dissipation plate 8 installed, and use the cold heat generated by the Peltier element 10 to insulate the inner cylinder 1 through the cold storage material 5. It is.

In this case, if the cooling capacity of the Peltier element IO is increased, the cost will increase and the amount of heat radiated from the heat sink 8 will also increase, making the container unsuitable as a portable container. For this reason, the cooling capacity of the Peltier element 10 is kept to an appropriate level, and the household power source is converted to DC the night before going out or before use, and the Peltier element 10 is activated to gradually cool it down.

Then, when you go out, carry the cord 15 with you, and if you can use a bathtub for cars or bicycles, use it to supply direct current to the Peltier element 10. By operating the
The cold insulation effect can be more reliably achieved.

Another embodiment of the invention will be described based on FIGS. 5 to 10. That is, as shown in FIGS. 5 to 7, in this cooling container, cooling objects such as canned drinking water are housed vertically in a cylindrical body 20 due to portability and design considerations. It is something.

The cylinder body 20 is disassembled into two parts in the longitudinal direction, and one side is the lid body 2.
1, and the other is the cylindrical body 22 that accommodates the coolant 30. The lid 21 is hinged to the main body 22 by a hinge 23 at one side, and can be detached from the main body 22 by engaging a locking tool 24 and a locking piece 25 at the other side.

Further, as shown in FIG. 8, a cold storage material 27 is provided at one end of the cylindrical body 20, which is sealed and sealed within a thermally conductive cooling cylinder 26. A Peltier element support 28 is detachably attached to one end of the cylinder 20 so that the Peltier element 29 is pressed against one end surface of the cooling cylinder 26. That is, one end surface of the cooling cylinder 26 is exposed to the outside from the cylinder 20, and a screw groove 26a is provided on the outer peripheral surface of the cooling cylinder 26 protruding from the cylinder 20, so that the Peltier element support 28 is screwed into the cooling cylinder 26.

With such a configuration, even if one end of the cylindrical body 20 is cooled by the Peltier element 29, it is difficult for the cold heat to reach the other end. A heat pipe 31 with a very high heat conduction effect is extended. This heat pipe 31 has one end in contact with the cooling cylinder 26 and transfers cold heat to the other end as efficiently as possible, and the main body 22
The coolant 30 is cooled through the inner surface of the coolant 30 . In this embodiment, as shown in FIG. 9, heat pipes 31 are built into each side of the cylindrical body 22, but a plurality of heat pipes 31 may be built in at appropriate intervals. . Furthermore, a cooling object 30 is provided inside the cylinder main body 22 and the lid body 21.
Thermal insulation material 3 is used to block heat exchange between the housing chamber and the outside air.
2 is filled.

As shown in FIGS. 8 and 10, the Peltier element support body 28 is provided with a Peltier element 29. A heat sink 34 that is in close contact with this Peltier element 29. A fan motor 35 and a forced cooling fan 37 pivotally supported by a rotating wheel 36 of the fan motor 35
is arranged. An air intake port 38 and an air discharge port 39 are provided on the circumferential surface of the cover 33 corresponding to the heat sink 34 and the forced cooling fan 37, respectively, and a ring-shaped fan bell mouth 40 partitions between them. Therefore, when the Peltier element 29 is activated, the fan motor 35 is driven to suck air from the air intake port 38.
The heat radiating plate 34 is cooled and forcibly exhausted from the exhaust port 39, and the high heat from the heat generating surface of the Peltier element 29 can be efficiently and quickly radiated into the atmosphere.

Since the cover 33 of the Peltier element support 28 is simply screwed onto the cooling cylinder 26 of the cylinder body 20, the Peltier element support body 28 can be separated from the cylinder body 20, as in the previous embodiment. With the Peltier element support 28 removed, the lid 21 of the cylindrical body 20 can be opened, and a cooling bottle 30 can be put in to pre-cool it in an electric refrigerator. When the Peltier element 29 is used, the Peltier element support 28 is attached and the female connector 43 of the power cord 42 is connected to the male connector 41 connected to the Opeltier element 29 to supply direct current and cool the inside of the cylinder 20. .

In this embodiment, the heat dissipation plate 34 is forcibly cooled by the fan 37, but the heat dissipation plate 8 may simply have the heat dissipation fan 12 as in the previous embodiment, or vice versa. The heat sink 8 may have a forced cooling structure as in this embodiment.

〔Effect of the invention〕

According to this invention, the Peltier element support body to which the Peltier element is attached can be separated from the cylindrical body and precooled in a refrigerator or the like, and when the body is carried out, the Peltier element support body can be attached to enhance the cold insulation effect. Moreover, if the Peltier element is operated with a DC power supply without using a refrigerator or the like, cooling can be easily performed regardless of whether indoors or outdoors.
