Description

  The present invention is a simple type for keeping a container for drinking for a relatively short period of time after taking out a container such as a bottle or a can containing a drink from a heat-retaining facility such as a refrigerator or a heat-retaining container for a relatively short time. The present invention relates to a heat and cold insulation device.

Wine, beer, and the like are taken out of the refrigerator, arranged on the table, and consumed as appropriate at the same time as the meal. Wine or the like is kept in a bowl-shaped container in which ice is stored so that the flavor does not drop during the meal.

On the other hand, as a tableware for an electromagnetic cooker, a plate made of a carbon material is fixed to the bottom of an aluminum pan or a frying pan is known (see, for example, Patent Document 1).

Moreover, the technique using what baked and solidified carbon powder and made it planar shape as a plate for heat cooking is known (for example, refer patent document 2).
JP 2003-38346 A JP-A-6-327568

As disclosed in the above patent document, the carbon material has good heat conduction characteristics (about half of aluminum), and has the characteristic of radiating energy obtained from a heat source as far infrared rays having a peak near a wavelength of 2 μm. It is very excellent as a material of electrical equipment for heating, heat insulation, etc.

On the other hand, as described above, ice can be stored at present as a device for cooling (cooling) a container containing wine or beer so that the temperature of wine or beer does not rise in a short time between meals. There are only ball-shaped containers (hereinafter referred to as ice storage containers). Since this ice storage container can hold a plurality of wine bottles after putting ice, it has a considerably large volume and is bulky.

Therefore, the ice storage container is usually prepared on a table different from the table and placed on the table, and the wine placed on the table is once returned to the ice storage container, or the wine stored in the ice storage container. It is necessary to take out and arrange them on the table again. The above operation is troublesome, and when eating such a form (barbecue etc.) outdoors in summer, the temperature of beer, wine, etc. taken out of the ice storage container rises within a short time. The flavor goes down.

Therefore, the present inventor uses a carbon material having a good thermal property as a coaster type simple device that can keep wine and beer in a cold state without using an ice storage container as described above. Recalling that it was manufactured, various prototypes were made. However, when carbon materials were used, there were the following difficulties.

That is, it was found that the carbon material is excellent as a material for heat insulation and heating, but is difficult to bend and form, is weak against impact, and has a defect that carbon powder adheres when touched on the surface. In other words, it has been found that it is extremely difficult to produce a product by using a carbon material to form a coaster shape that matches the bottom shape of a wine or beer bottle.

When copper, which is generally said to have excellent heat conduction characteristics, is used, although the heat conduction characteristics itself is excellent at 0.923, the specific heat is as small as 0.092 cal / g · degree. It was found that a large amount of energy was required for the cooling source, and it was not suitable as a material for a simple desktop device. In other words, the fact that a large amount of energy is required means that the power source must be an AC power source, or that a very large battery is required, making it difficult to design for desktop use.

Therefore, the inventor of the present invention creates an outer body having a hollow portion from aluminum, resin, etc., and forms the inner shape of the outer body into a shape that fits into the bottom of a wine or beer bottle, and in the hollow portion. Recalled that the carbon material was inserted in a split mold, and the present invention could be completed.

The outer peripheral cylindrical portion 3a and the bottom upper plate 3b1 are integrally formed of aluminum or resin, and the inner side surface of the outer peripheral cylindrical portion 3a and the upper surface of the bottom upper plate 3b1 are formed into a shape that substantially fits the bottom portion of the beverage bottle 2. In particular, the upper surface of the bottom upper plate 3b1 is molded into a shape in which the center is raised in a gentle mountain shape. Heat exchange is performed efficiently.

Next, the shape of the outer shell 3 and the shape of the carbon material 4 accommodated in the hollow portion will be described in detail with reference to FIGS. 3 to 5. 3 to 5 show the structure of the carbon material 4 and the outer shell 3 along the assembling process.

As shown in FIG. 3, in the hollow part of the outer peripheral cylindrical part 3a of the outer shell 3, a divided cylindrical divided type (carbon material) 4a whose circumference is divided into eight parts is housed. In the state in which the eight divided cylindrical divided dies 4a are accommodated, as shown in FIG. 4, the lower surface of the bottom upper plate 3b1 and the end surface of each divided cylindrical divided mold 4a constitute one plane. The disc-shaped division type (carbon material) 4b is accommodated so as to be in close contact with the plane.

As shown in FIG. 5, the outer shell 3 in which the disk-shaped split mold 4b is housed has a single bottomed cylindrical shape, and a donut with a hole 14 in the center made of a heat insulating resin at the bottom. The bottom bottom plate 3b2 having a shape is fixed using a fixing tool such as a screw 13. The outer shell 3 in which the carbon material 4 is housed in the hollow portion as described above is referred to as a heat transfer unit U.

Returning again to FIG. A carbon material (disc-shaped division type) 4b is exposed from the hole 14 opened in the bottom lower plate 3b2 of the heat transfer unit U, and the Peltier element 5 is mounted so as to be fitted into the hole 14. The heat exchange surface (surface) of the Peltier element 5 is in contact with the carbon material 4b. In FIG. 2, the surface of the Peltier element 5 and the lower surface of the carbon material 4 b are shown apart from each other to clearly show the temperature sensor 6, but the surface of the Peltier element 5 and the lower surface of the carbon material 4 b may be in close contact with each other. preferable.

In this embodiment, a thermistor is used as the temperature sensors 6 and 7 and is fixed so as to be embedded in a grease-like heat transfer filler applied to the surface of the Peltier element 5. In FIG. 2, wiring between the temperature sensors 6 and 7 and the Peltier element driving circuit 8 is omitted.

And the heat-transfer unit U comprised as mentioned above is accommodated in the outer case 12 made from resin. A space S is formed between the bottom of the outer case 12 and the bottom of the heat transfer unit U, and air sucked by the fan 11 passes through the radiator 9 and is discharged to the opposite side of the outer case 12. An air suction hole 15 is formed on the surface of the outer case 12 facing the fan 11, and an air discharge hole 16 is formed on the opposite side of the outer case 12.

In the space S between the bottom of the outer case 12 and the bottom of the heat transfer unit U, the Peltier element driving circuit 8 and the power supply battery for the fan 11 and a power supply circuit (not shown) are stored. In the present embodiment, a lithium ion battery is used as the power supply battery.

Next, operation | movement and the usage method of the cold insulator 1 of this embodiment are demonstrated. First, as shown in FIG. 1, the beverage bottle 2 is inserted in a standing posture into the cold insulation device 1 of the present embodiment. When the switch is turned on in this state, the Peltier element 5 is driven and heat is absorbed from the front surface side (temperature sensor 6 side) of the Peltier element 5 and is released to the back surface side (temperature sensor 7 side). The carbon material (disc-shaped division type) 4b of the unit U is cooled.

By cooling the carbon material (disc-shaped division type) 4b, the entire heat transfer unit U is gradually cooled, and the beverage bottle 2 is cooled. At this time, since the bottom portion of the beverage bottle 2 is substantially in close contact with the heat transfer unit U, the beverage bottle 2 is efficiently cooled. Since the bottom surface of the carbon material (disc-shaped split type) 4b is covered with the bottom lower plate 3b2 made of heat insulating resin, it is exposed to a room temperature space S between the bottom of the outer case 12 and the bottom of the heat transfer unit U. And the temperature rise of the carbon material (disc-shaped split type) 4b is suppressed. Further, since the outer shell 3 is made of aluminum or resin, it is lightweight and easy to handle, and heat transfer efficiency is good.

The Peltier element 5 is driven so that the temperature difference between the front and back sides of the Peltier element 5 becomes a predetermined value (for example, 30 degrees). The Peltier element driving circuit 8 controls increase / decrease of the supply current to the Peltier element 5 so that the temperature detected by the temperature sensor 6 on the surface side of the Peltier element 5 becomes a target temperature (for example, 0 degree).

When the temperature detected by the temperature sensor 7 on the back side of the Peltier element 5 exceeds the range of room temperature, the fan 11 is driven to dissipate heat on the back side of the Peltier element 5 via the radiator 9. As a result, the temperature on the back side of the Peltier element 5 is lowered to about room temperature, and the temperature on the front side of the Peltier element 5 is lowered to about 0 degrees Celsius.

When the beverage bottle 2 is lifted, if the user grasps the upper part of the beverage bottle 2 by hand and pulls it upward, the cold insulation device 1 has an appropriate weight, so that the bottom of the beverage bottle 2 heat-transfers. Despite being inserted in close contact with the unit U, only the beverage bottle 2 is smoothly drawn upward. Further, since the entire circumference of the carbon material 4 is covered with the outer shell body 3, the surface carbon powder does not adhere to the user.

As described above, in the cold insulation device 1 of the present embodiment, the beverage bottle 2 (beverage) is simply inserted into the coaster type cold insulation device placed on the table in a standing posture from the beverage bottle 2 taken out from the refrigerator or the like. Is moderately cooled. In addition, since most of the cold insulator 1 is made of the carbon material 4, it is lightweight and requires less power consumption.

Note that if the polarity of the current supplied to the Peltier element 5 can be switched, the Peltier element 5 acts to absorb heat on the back side and dissipate heat on the front side, so that it can also be used as a heat retaining device.
