Description

Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION The present invention relates to beverage dispensers.

[0002]

2. Description of the Related Art Recently, as a beverage supply facility, a back-in box filled with a beverage raw material (concentrated liquid such as syrup) is loaded inside the machine body together with an outer box, and the raw material and dilution water are mixed and poured out. Beverage dispensers, which are designed to dispense a fixed amount into a cup from a nozzle of the part, are widely used.

The above-mentioned back-in-box comprises a double bag having an inner bag 1 and an outer bag 2 and a pressure fluid ( The inner bag 1 is pressurized by supplying compressed air) and the liquid (raw material) in the inner bag 1 is discharged from the nozzles 3, and the nozzles 3 are provided at the openings of the inner bag 1 and the outer bag 2. Has a nozzle body 4 which is tightly fixed by welding or the like, and a side portion of the nozzle body 4 is provided with a hose connection portion 6 for allowing compressed air to flow into the space 5 between the inner and outer bags 1 and 2. A pressure fluid passage 7 communicating with the space 5 is formed, and these are housed in an outer box 8 made of cardboard or the like to form a back-in-box 9 as shown in FIG. 7.

A conventional beverage dispenser using such a back-in box 9 stores a cooling water tank for cooling, a cooling compressor, and a back-in box in the body, and circulates cooling water from the cooling water tank. It contains a pump and other auxiliary equipment.

In the conventional arrangement of the above-mentioned equipment, a heavy compressor is installed in the lower part of the machine body, a cold water tank is arranged just above the compressor, and a back-in-box is housed in the upper part of the front side of the machine body. The nozzle of the back-in-box faces the pouring mechanism at the front of the machine body and pours out.

[0006]

However, with the above-described conventional arrangement structure, the cold water tank and the compressor have both a volume and a bottom area of the cold water tank larger than that of the compressor, and therefore, the cold water tank and the cooling compressor. In addition to the installation space for and, it is necessary to secure a space for heat exchange air passages, piping, and wiring inside the machine body, which causes a problem that the outer size of the machine body becomes large.

Further, since the cold water tank is located directly above the compressor, when structural damage occurs in the cold water tank and water leakage occurs, the cooling water directly splashes on the compressor and is temporarily damaged. Even if it does not occur, it is difficult to avoid that heat is dissipated from the compressor to the lower surface and side surfaces of the cold water tank, causing dew condensation on the outer surface of the cold water tank, which then becomes water drops and splashes on the compressor.

In view of this, the present invention is a compact beverage dispenser in which the outer dimensions of the machine body can be reduced, no troubles occur in the machine body, and the breathability and the layout of other devices are not hindered. The purpose is to provide.

[0009]

As a means for solving the problems of the above-mentioned prior art, the present invention provides a cooling water tank for refrigerant at a lower position inside a machine having a pouring mechanism at an overhanging portion projecting to the upper front. It is installed, the middle shelf is provided at the upper position of this cold water tank, the compressor for cooling is mounted on it, the storage part of the back-in box is located in the overhang part, and the lower part and the side part of the cold water tank are cooled. It is characterized by being used as an air passage.

[0010]

[Function] Since the cold water tank is installed in the lower part of the fuselage and the compressor is installed above it, there is no influence of water or water drops from the cold water tank on the compressor, and the bottom area Since the small compressor is located in the upper part, a sufficient heat exchange air passage, piping, and wiring space can be secured, and ventilation to the compressor is secured, so that heat dissipation conditions are favorable. Further, the cooling air flows smoothly because it flows through the outer peripheral portion of the cold water tank. With these, the outer shape of the body can be made small, but the functionality is not deteriorated.
