DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A first embodiment of the present invention is shown in FIG. Front duct 12 covering the front from the upper surface of the main body 1 of the vending machine
Is provided in front of the machine room 2, and an intake port 1a and an exhaust port 1b are provided.
The front duct 12 and the machine room 2 are divided into left and right shunts and branch chambers by a partition plate 2a, and the upper end of the front duct 12 serves as an intake port 12a and an exhaust port 12b. Since the back surface side of the machine room 2 of the partition plate 2a is notched, the air that has passed from the intake port 12a to the intake port 1a by the blower 35 is compressed by the compressor 33.
Then, the condenser 34 is cooled and is discharged from the exhaust port 12b through the other compartments and the exhaust port 1b. In this example, since the opening of the machine room 2 is not provided in the front of the vending machine, the noise of the blower and the compressor is less likely to be radiated from the front of the vending machine, and the noise around the front of the vending machine can be reduced.

A second embodiment of the present invention is shown in FIG. In this example, the vending machine of the conventional example is provided with front and rear ducts. The front duct 12 covering the front side from the upper part of the main body 1 has an intake port 12a facing the rear side at the upper part of the main body 1, and the other end is electrically connected to the intake port 1a of the machine room 2, and the back duct 11 is connected to the machine room 2 Is connected to the exhaust port 1b of the exhaust port 1b
1b is directed upward. According to this structure, the blower 35
The air generated by the compressor 3 is discharged from the intake port 12a through the intake port 1a and the exhaust port 1b through the exhaust port 11b.
However, since there is no opening in the front of the front duct 12, the blower 35 and the compressor 33 are not affected by the cooling effect of the compressor 3 and the condenser 34.
Noise is less likely to be radiated from the front of the vending machine, and the noise around the front of the vending machine can be reduced.

A third embodiment of the present invention is shown in FIG. Inside the machine room 2 of the main body 1 of the vending machine, three partition chambers are provided laterally by the partition plate 2a and the partition plate 2b, and the intake port 1a is provided on the rear surface in the partition chamber in which the compressor 33 and the condenser 34 are built. An exhaust port 1b is provided in front of the end compartment. Since the partition plate 2a is notched on the front side and the partition plate 2b is cut on the back side, it is possible to discharge the air sucked from the intake port 1a by the blower 35 from the exhaust port 1b through the other two branch chambers. . In this example, the cooling machine in the machine room 2 in front of the vending machine does not have an opening in the front of the branch room, and the exhaust port 1b is in front of the branch room at the end, so the direct noise of the cooling machine is diffused from the front. Instead, the sound around the front of the vending machine can be reduced because it is attenuated by the effect of distance due to acoustic reflection in the compartment and the length of the duct.

A fourth embodiment of the present invention is shown in FIG. In this example, the lower duct 13 having an opening in the front is provided in the lower portion of the main body 1 of the vending machine. Vending machine body 1
The inside of the machine room 2 and the lower duct 13 is divided into left and right branch chambers and shunts by a partition plate 2a, and an intake port 1a and an exhaust port 1b are provided on the back side of the bottom of each of the machine chambers 2. Since the partition plate 2a is notched only on the front side of the machine room 2, it is compressed by the air sucked by the blower 35 from the intake port 13a of the lower duct 13 to the intake port 1a of the branch chamber.
3 and the condenser 34 are cooled and discharged from the other compartment through the exhaust port 1b and the exhaust port 13b. In this example, since the intake port 13a and the exhaust port 13b are provided only in the lower duct of the vending machine, it is difficult for the noise of the blower and the compressor to be directly radiated from the front of the vending machine, and the sound reflection in the branch room and the duct noise. It is possible to reduce the noise around the front of the vending machine because it is attenuated by the effect of distance depending on the length.

A fifth embodiment of the present invention is shown in FIG. This example has a structure in which ducts are provided on the front and bottom of the vending machine. Front duct 12 covering the front from the top of the main body 1
Has an intake port 12a facing the back at the upper part of the main body 1, and the other end is connected to the intake port 1a of the machine room 2, and the lower duct 1
3 is electrically connected to the exhaust port 1b of the machine room 2 so that the exhaust port 13b faces the front. According to this structure, the air from the blower 35 passes through the machine room 2 through the intake port 12a and the intake port 1a, and is exhausted through the exhaust port 1b and the exhaust port 13b, so that the cooling effect of the compressor 33 and the condenser 34 remains unchanged. In addition, the direct noise of the blower and compressor is less likely to be radiated from the front of the vending machine, and the noise around the front of the vending machine is reduced because it is attenuated by the reflection of sound in the branch room and the effect of distance due to the length of the duct. Is possible.

In each of the above embodiments, it is possible to further reduce the noise by providing a large number of sound wave rectilinear movement preventing members and sound absorbing materials in the duct or in the compartment.

[0017]

According to the first and second embodiments of the present invention, since the front opening is eliminated, the noise generated by the cooler is not directly emitted from the front, and the noise around the front of the vending machine can be reduced. It is possible to provide a vending machine that can be installed indoors where quietness is required.

Further, according to the third to fifth embodiments of the present invention, the ventilation path from the noise source to the front opening is bent or lengthened to enhance the noise damping effect. It is possible to provide an automatic vending machine which can reduce the noise and can be installed indoors where quietness is required. Further, according to the first, second, fourth, and fifth embodiments of the present invention, since the rear surface is not provided with the cooling opening, the rear surface can be brought into close contact with the wall, and the passage side It is possible to provide a vending machine with a small amount of protrusion.
