Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a water or beverage cooler. Conventionally, in small offices, shops, and homes, coolers that do not have a built-in cooling device that uses energy such as electricity have relied on ice as a cooling source because the object to be cooled is a drink. However, the cooling power of ice, that is, its ability to remove heat from the contents inside the container, is limited, and if used in large quantities, it has the disadvantage of diluting the contents, such as barley tea, to a moderate degree of concentration, and it also cools rapidly. There was also a lack of flexibility in this regard.

The present invention solves the above-mentioned drawbacks, and the present invention can be used if there is a refrigerator-freezer that is currently widely used in Japan. Embodiments will be described in detail below with reference to the drawings. The figure is an external view of the cooler of the present invention, with a portion thereof cut away for convenience of explanation. Reference numeral 1 denotes a vertical cylindrical outer container, which is a sandwich type double container made of inner and outer aluminum plates 3 with a heat insulating material 2 such as polyurethane interposed as a core material. A water tap 5 is provided in the body near the bottom 4 so that drinking water or the like can be taken out as needed. The upper mirror plate 6 has an inner container 8, which will be described later, at its center.
A round opening 7 is provided that is large enough to allow the passage of.
Although the outer container 1 is not limited to the above-mentioned heat-insulating container, it is preferable that it has as much heat insulation performance as possible.

Reference numeral 8 denotes an inner container, which is made of an aluminum plate and has a cylindrical shape with a bottom, and has a large number of through holes 9 on its outer periphery, so that the liquid can flow freely. Further, during use, a can-shaped cool storage body 10 is inserted into the inner container 8. In addition, near the upper edge of the inner container 8, a protrusion serving as a handle 14 protrudes from the inner surface for convenience in pulling out the inner container 8. In the illustrated example, the inner container 8 is a perforated plate made of aluminum, but if the outer dimensions are the same, a cylindrical casing made of corrosion-resistant linear material would be more effective for rapid cooling. play. The outer diameter of the inner container 8 must be equal to or slightly smaller than the inner diameter of the opening 7, but its height does not necessarily have to be equal to the inner height of the outer container, as shown in the figure. If the height is lowered, it is convenient to use the inner container 8 by attaching the feet to the bottom of the inner container 8 so that the upper edge of the inner container is inscribed in the opening 7, and it is efficient because the cooled liquid will drip downward. .

Reference numeral 11 denotes a cap made of synthetic resin or the like with good heat insulation performance, and a water injection hole 12 penetrates through the center for convenient replenishment of drinking water, etc., and a rod valve with a head 13 is installed in the water injection hole 12. The water injection hole 12 is sealed by 12'. Note that it is easier to operate if the rod valve has a gentle taper. In addition, the sealing means is illustrated in such a way that the outer container opening and the cap are screwed together.

Next, to explain the operation, the cold storage canister 10, that is, a sealed body filled with water or carbonated water as a heat medium, is pre-cooled in a hand-held freezer or refrigerator-freezer, etc., the medium is solidified, and then the cooler is heated. When in use, the cold storage bodies 10 are placed in an orderly manner into the inner container 8 inserted under the opening 7 of the outer container, and after pouring the beverage to be cooled through the opening 7, the lid is screwed on with the cap 11, and the rod valve 12 is closed. ’ to make sure the injection hole is sealed.

The injected drinking water undergoes heat exchange with the cold storage body 10 and is rapidly cooled. Note that if the inner container 8 is shaped like a basket or made of aluminum, which is a good heat conductor, the cooling efficiency will be further improved. Then, the cooled drinking water or the like descends and can be taken out into a container such as a pot as required by a water tap 5 provided in the outer container.

According to this cooler, it is possible to obtain chilled drinking water, such as cold coffee, barley tea, carbonated water, and fruit juice, which is diluted with water dissolved in ice and maintains a desired concentration without impairing the flavor. Also, if you plan to have a large number of guests, you can also fill it with beer to solve the problem of having a small refrigerator. As described above, this cooler is ideal for cooling not only water, but also beverages that require a constant concentration for flavor, noodle soup, etc. for commercial purposes. Furthermore, unlike ice, cold storage cans can store cold down to temperatures as low as -15°C, so they have multifunctional flexibility with respect to cooling capacity and cooling temperature. As a result, depending on the purpose of use, for example, it can be used to rapidly cool coffee, black tea, barley tea, etc. that are extremely hotter than room temperature, or it can be used to keep it cold at a constant temperature.Its uses are extremely diverse, whether for home or business use. intersect with
Further, by using the above-mentioned injection hole 12, it is possible to replenish the beverage even during cooling.

Claims (1)

[Scope of Claim for Utility Model Registration] (1) The outer container is formed of a vertical cylindrical double container filled with a heat insulating material such as polyurethane as a core material, and is equipped with a water tap at the bottom and an upper end panel. A round opening with a locking part on the outer periphery is provided at the center of the container, and a locking receptacle is provided on the inner periphery of the cap 11 made of synthetic resin, which is the lid of the outer container. It has a through hole into which a headed water injection rod valve is attached, and the inner container is made of aluminum alloy or the like and has a porous cylindrical shape with a bottom and an outer diameter approximately equal to the inner diameter of the round opening. After a desired number of cold storage bodies containing a heat medium are charged into the outer container, a beverage is poured into the outer container, and an inner container containing the cold storage bodies is installed directly below the round opening.
A cooler for drinking water, etc., which is sealed with the cap with the rod valve 12. (2) A cooler for drinking water, etc. according to claim 1 of the utility model registration claim, wherein the locking means of the cap is screwed.
