Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an apparatus for keeping a cooled liquid cool, and more particularly to a cooling apparatus for cooling soft drinks such as beer and other alcoholic beverages and juice to an appropriate temperature and holding the same for a long time.

[0002]

[Prior Art]

 Conventionally, when selling cold soft drinks, etc., at a store, a method of storing the drinking water for sale in a transparent container such as glass and introducing the drinking water into a cooler provided below to circulate and cool it Alternatively, there is a method in which drinking water contained in a pressurized container is cooled through a spiral tube provided in a cooler and then poured into a cup.In the former case, a relatively small volume container for juice or the like. In the latter case, the cooling efficiency and equipment cannot be increased because the operation is carried out in a shielded state from the store front.

Further, it has been practiced to put a cooled liquid content in a container whose surface is insulated, and to sell the liquid content at a store. The problem arises that the container has to be repeatedly moved in and out of a special refrigerator installed in the store for cooling to the temperature.

[0004]

[Problems to be solved by the device]

 As described above, it is difficult to keep the liquid contents cold at a low temperature of several degrees Celsius for a long time even if the surface of the container is insulated, and the internal liquid temperature rises quickly and quickly due to the influence of the outside air. In many cases, the temperature will rise above the appropriate temperature. When the temperature exceeds the optimum temperature, it has to be lowered to the proper temperature again, but even if a dedicated refrigerator is used, it will take several hours to reduce the operating efficiency.Even if the dedicated refrigerator is not used, the spout can be poured from the container. A cooling device must be installed between the two, and therefore the increase in equipment costs is inevitable.

The present invention solves such a problem, and the liquid container is partially housed in a refrigerating box integrated with a cooling device so that the liquid container can be put in and out, and the liquid in the container is kept at an optimum temperature. An object of the present invention is to provide a liquid cooling / cooling device that can provide customers with special recognition of the source of liquid contents by keeping a cold, using a special container such as shape and color, and exposing a part of it. And

[0006]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention has the following configurations. That is, (1) at least the exposed portion of the liquid storage container has a heat insulating structure, and at least 65% of the liquid storage container can be taken out into a cool box constituted by a heat insulating wall incorporating an electronic cooler. It is a liquid cooling / cooling device that is stored secretly and a part (less than 35%) of the container is exposed from the cold storage box. (2) An electronic cooler is installed in the cold storage box with heat insulation structure and the front wall Part and a side wall part are provided with an opening / closing door, and at least a part of the liquid container having an insulating structure at the exposed part, that is, less than 35% of the surface area is exposed, but at least 65% of the surface area is exposed in the cold insulation box. It is a liquid cooling / cooling device which is housed inside and is provided with a seal that can seal the wall and door of the cold storage box with the exposed part of the liquid storage container.

The present invention will be described below based on the embodiments shown in the drawings. FIG. 1 is a perspective view of the present invention, and FIG. 2 is a top view thereof, where 1 is a liquid container and 2 is a cold box. At least 65% of the surface area of the liquid container 1 is housed in the cool box 2, and the entire surface and a part of the upper side surface are exposed. That is, 3 is the exposed portion of the container 1, and the exposed area is less than 35% of the container surface. However, the exposed portion 3 has a minimum heat insulating structure. The cold-retaining box 2 is a hollow box body configured to house the liquid storage container 1 as described above, and which is composed of upper and lower heat-insulating side walls that hermetically bend and surround the periphery. The hinges 6 and 6 are attached to the two cold storage boxes so that they can be opened and closed. These doors 4 and 5 are provided in order to put the container 1 in and out of the cold storage box 2, but only one of them may be provided. Reference numeral 7 denotes an electronic cooler incorporated in the back wall of the cool box 2, for example, a Peltier element (semiconductor element for electronic cooling) is used. Numeral 8 is an auxiliary room that houses a DC power supply and the like. Reference numeral 9 denotes a seal packing made of sponge rubber or the like provided on the side wall of the cold insulation box 1, which is in contact with the liquid storage container 1, the ceiling and the doors 4 and 5, and shields the atmosphere from the inside of the box.

The present invention has the structure as described above, and a state in which a part of the insulated container 1 is exposed in the cold insulation box 2 in which the electronic cooler 7 of the electronic cooler (Peltier device) is incorporated. Alcoholic beverages, soft drinks, etc., stored in a container, are kept cool at an optimum temperature by exposing a part of the surface of the container, especially the upper part, and making at least this exposed part 3 a special shape. As a result, it is possible to display an image that makes it possible to distinguish the brand of the filling contents and the manufacturing origin. However, if the area of the exposed container portion 3 becomes too large, the heat effect from the atmosphere will increase, and it will be difficult to hold the container at a proper temperature as low as several degrees Celsius for a long time, especially for beer. Although the material for forming the exposed portion and the thickness thereof affect the cold insulation, according to the experiments of the present inventor, beer was filled in the container 1 in which the exposed portion 3 was formed with a hard urethane resin having a thickness of 5 mm, It was found that an exposure rate of up to about 30% of the surface area of the container is required to stably obtain a target temperature of 7 ° C or lower for a long time, and an exposure ratio of up to around 35% is similarly acceptable to obtain a target temperature of 10 ° C or lower.

Therefore, at least the exposed portion has a heat insulating structure made of urethane resin or the like, and the degree of exposure is less than 35% of the container surface area. Most preferred is 20-30%. Further, it goes without saying that the entire container 1 may have a heat insulating structure, but it may be difficult for the cold temperature in the cool box due to the cooling of the Peltier element 7 to be transmitted, so it is preferable to use only the exposed part.

The electronic cooler attached to the present invention cannot be made so large in terms of equipment and has a low cooling capacity. Therefore, the outer wall of the cold insulation box 2 has a heat retaining structure in order to enhance the cooling effect. FIG. 3 is a cross-sectional view taken along the line AA of FIG. 1 showing an example of the wall structure. Alternatively, a plastic material (0.20 cal / mh ° C) is used, and a metal plate such as an aluminum plate having a good heat conduction effect in the direction of cooling the inner surface 11 is used, and a hard urethane is used between the outer frame 10 and the inner surface 11. A heat insulating intermediate material 12 such as foam, asbestos material, glass wool or polystyrene material is provided and integrated with an adhesive, but it is practical to laminate aluminum foil on one surface of hard urethane foam.

Further, the inside of the box 2 which is insulated from the outside and surrounded by the wall of the internal heat retaining structure has a space as narrow as possible so that the cool air discharged from the heat-absorbing fins of the Peltier element circulates well. For that reason, it is preferable that the corner portion of the box 2 is provided with an oblique cut plate 13 to which an aluminum plate or the like is attached so as to be compact. Furthermore, a space 14 is provided between the auxiliary chamber 8 and the cold insulation box 2 so as to block the heat generated from the DC power supply 15 installed in the auxiliary chamber.

As described above, according to the present invention, even though a part of the container to be kept cool is exposed from the cool box, it is possible to keep the cool box by itself at an appropriate temperature, and it is easy to put it in a suitable place. It is extremely convenient because it can be moved to the location.

Next, a usage example of the present invention will be described. As shown in FIG. 1, a liquid resin container (barrel) 1 made of urethane resin has a front surface of the same structure as a peripheral wall composed of an outer frame made of wood, a heat insulating intermediate material made of hard urethane foam, and an inner wall made of aluminum. A cool box 2 having a door and a side door is housed so that approximately 25% of the total surface area is exposed, and a Peltier element 7 connected to a DC 24 V power supply 15 installed in the auxiliary chamber 8 is used to open the cool box from the back. Cooled for hours. The container 1 was filled with beer cooled to approximately 5 ° C. in advance.

FIG. 4 shows changes in room temperature, upper temperature in the barrel, lower temperature in the barrel, and temperature in the cool box. As is clear from this, when the temperature inside the cool box was kept at around 0 ° C, the temperature inside the container showed a little difference between the upper and lower sides during 24 hours, even though the ambient temperature was as high as 24 to 27 ° C. It does not occur and is stably maintained at approximately 5 to 6 ° C, and is kept cold near the target value for a long time.

[Effect of the device]

 As described above, according to the present invention, by exposing a part of the contents storage container and storing it in a cool box composed of a heat insulating wall, the container image is displayed and the influence from the outside air is minimized. The contents of the container can be kept cool at the target value stably for a long time. In addition, it is easy to move the container in and out of the cool box, and it is easy to move only the cool box, and since the electronic cooling device is incorporated, there are no restrictions from the refrigeration equipment and the installation location can be freely selected. Furthermore, the contents of the filling and the manufacturer can be clarified by the container image.
