FIG. 3 is a cross-sectional view of the beverage supply device according to the embodiment of the present invention. In the figure, the heat insulating box 11 is provided with a cooling chamber 11a surrounded by a heat insulating wall and a machine room 11b arranged on the back side thereof. A refrigeration unit 12 is provided at the back of the cooling chamber 11a.
A cooler 12a and a fan 12b in the refrigerator are arranged, and a compressor 12c, a blower fan 12d, a condenser 12f, a temperature controller 12g, and the like, which constitute the refrigerating apparatus 12, are arranged in the machine room 11b. . The temperature control unit 12g inserts the detection unit 12g1 into the cooling chamber 11a, and the compressor 12
The temperature of the inside of the cooling chamber 11a is kept within a predetermined range by controlling operations such as c.

Inside the cooling chamber 11a, the duct 1 is provided on the front side of the cooler 12a and the internal fan 12b arranged at the back.
3 is provided, and the beverage tank 15 is stored therein. The beverage tank 15 has a screw-type opening on the upper side, has a through hole communicating with the upper and lower surfaces, and is covered with a substitute plug 17 penetrating a suction pipe 18 in the through hole. .

The heat insulating box 11 is a heat insulating door 2 whose front surface can be opened and closed.
As shown in FIGS. 2 and 3, the pump motor 31 is wrapped with a cushioning material 32 having a vibration-proof and sound-proof property, for example, a soft polyurethane foam, and then covered with a mounting bracket 33. The end of the metal fitting 33,
Bracket 3 attached to heat insulation door 20 with screws or the like
4 is fastened to the pump motor 31 by screws or the like.
The cushion material 32 is provided on the front surface of the heat insulating door 20.

Further, the inside of the fitting 33 is shown in FIG.
As shown in FIG.
By providing b and 33c, the cushion material 32 may be prevented from coming off even by the vibration of the pump motor 31.

The hemispherical cover 35 covering the pump motor 31 is formed by connecting the cylindrical cover 36 with screws or the like, and the flange portion of the cylindrical cover 36 is fixed with screws or the like above the front surface of the heat insulating door 20. It may be covered with only the hemispherical cover 35 without being connected to the cylindrical cover 36. The suction tube 22a of the pump motor 31 penetrates the heat insulating door 20, is inserted into the cooling chamber 11a, and is connected to the suction pipe 18 of the beverage tank 15 in the cooling chamber 11a.

A front cover 24 is arranged above the front side of the heat insulating door 20 so as to cover the pump motor 31, the cushion member 32, the fitting 33, the bracket 34, the cylindrical body 23, the hemispherical cover 35 and the cylindrical cover 36. It is set up. The front cover 24 is also provided with an operation switch 25a which is a control unit 25 for operating the beverage supply device, and the operation switch 25a of the control unit 25 penetrates the front cover 24 and projects to the front side.

Next, the operation of the present embodiment having the above configuration will be described. A beverage for cooling, for example, cold liquor, is put in the beverage tank 15, a suction pipe 18 is inserted into the opening, and the lid 17 is capped with a substitute plug 17. When the refrigerating device 12 in the machine room 11b operates, the inside of the cooling room 11a is cooled under the control of the temperature controller 12g, and the beverage in the beverage tank 15 is also cooled and held within a predetermined temperature range.

A container such as a sake bottle is placed on the tray 26, and when the operation switch 25a is operated, the control unit 25 operates the pump motor 31 to suck the beverage in the beverage tank 15 and the container on the tray 26. Poured into.

Here, when the pump motor 31 operates, vibration and noise are generated due to the operation of the pump motor 31, and the pump motor 31 has a cushioning material 32 for vibration and sound insulation, a mounting member 33 and a bracket 3.
Since it is sandwiched between the mounting bracket 33 and the bracket 4, the vibration and noise of the pump motor 31 itself are suppressed, and the vibrations of the mounting bracket 33 and the bracket 34, which are generated by the resonance with the pump motor 31, are also suppressed.

Vibration and noise that cannot be suppressed even by the cushion material 32 are the hemispherical cover 35 and the cylindrical cover 3.
Since it is shielded by 6 and 6, it is more rigid than a cube composed of a flat surface, and is less likely to resonate due to resistance to vibration and noise, and the sound leaking to the outside of the hemispherical cover 35 and the cylindrical cover 36 is It is getting smaller.

Further, the pump motor 31 has a cushion material 3
Since it is covered with 2, the dust is prevented from entering the pump motor 31.

[0017]

According to the motor mounting structure of claim 1 of the present invention, a cushion material is wound around the outer periphery of the main body of the motor, the cushion material is covered with a band-shaped mounting metal fitting from the outside, and the mounting metal fitting is mounted on the bracket arranged in the box body. Since the motor is fixed and the motor is attached to the box body, the vibration and noise generated from the motor are suppressed by the cushion material wound around the motor and are reduced.

Further, according to the motor mounting structure of claim 2 of the present invention, by attaching the hemispherical cover to the box so as to hermetically cover the motor mounting structure of claim 1, vibration and noise generated from the motor are prevented. The cushion material covered by the motor provides vibration and noise insulation, and vibration and noise that cannot be suppressed even by the cushion material reach the hemispherical cover, but the hemispherical shape provides rigidity and is resistant to vibration and noise. Resonance makes it difficult to resonate, and the sound leaking to the outside of the hemispherical cover is even lower.
