Description

[Detailed description of the invention] The present invention relates to a temperature range control device for a vending machine, which can be switched between cooling the entire vending machine and cooling a portion of the machine, making effective use of power consumption. The aim is to

In conventional vending machines, whether to cool the entire interior or to partially cool the interior is determined at the design stage, and cannot be changed after installation to suit the number of bottles sold or other conditions.

Therefore, if a vending machine designed to cool the entire machine is installed in a place where the number of machines sold is small, the power consumption will be higher than the number of machines sold.

On the other hand, if a partial cooling vending machine is installed in a place where a large number of products are sold, it has the disadvantage that the products are sold before they are sufficiently cooled.

The present invention provides a cooling device for a vending machine that takes the above points into consideration.

An embodiment of the present invention will be described below with reference to the drawings.

Reference numeral 1 is a body forming a casing of a vending machine,
A door 2 is pivotally attached to the front opening of the body 1.

Although not shown, the door 2 is provided with a coin slot, a selection button, a sales slot 3, and the like.

Reference numeral 4 denotes product storage columns in the form of serpentine tracks for storing cylindrical products 5 such as cans, which are arranged in three rows in the front and back, and are each provided with a conventionally known product release mechanism 6 below.

This product storage column 4 is placed in the heat insulated storage compartment 7 of the aircraft body 1.
is accommodated.

A machine room 8 is formed below the body 1, including an electric compressor 9 for a cooling cycle, a condenser 10, and a blower 1 for discharging heat.
1 is provided.

Further, a cooler 12 is provided at the bottom of the heat-insulating chamber interior 7.

A guide plate 13 is attached to the upper part of the cooler 12, and an air circulation path 14 for circulating the air inside the heat-insulating chamber 7 is formed.

15 is a blower installed in the air circulation path 14, and the door 2
The liquid is discharged toward the sales outlet 3 and circulated upward in the refrigerator interior 7 along the door 2.

Reference numeral 16 denotes a chute for guiding the products discharged from the product storage column 4 to the sales outlet 3, and is formed in an inclined and tapered shape.

This chute 16 is formed with an air port 17 for air circulation.

Reference numeral 18 denotes a shield plate in which a guide hole 20 is inserted into a pair of pins 19 formed in the chute 16, and the degree of opening of the air outlet 17 is adjusted by a lever 21.

The lever 21 is formed in an L-shape and is connected to a long hole 22 of the stiffening plate 18 by a pin 23.

In such a device, the lever 21 operates the shield plate 18 in the opening direction in FIG.
As indicated by the solid line arrow in the figure, convection occurs in the center or lower part of the refrigerator interior 7, and only the lower part of the refrigerator interior is cooled to a predetermined temperature.

Furthermore, by operating the lever 21 and sliding the shield plate 18 in the closing direction in FIG. (broken line arrow in the figure) cools the entire refrigerator interior 7.

Therefore, by changing the opening area of the air outlet 17 of the chute 16 depending on the installation location by moving the shield plate 18,
Since the inside of the refrigerator can be easily switched between total cooling and partial cooling, it can be installed in any location with any sales frequency.

Furthermore, since the inside of the refrigerator is kept at a constant temperature by a thermostat, the operating rate of the electric compressor 9 can be changed by total cooling and partial cooling, thereby saving energy.

Although the embodiments have been described using a cooling cycle as an example, the same effect can be obtained even when the product is heated.

In this way, the present invention sends cold air or warm air, etc., sent from the blower to the product storage room, so it is possible to control the range of the cold air, etc., for example, to the middle of the product storage column, or to the entire product storage column. In addition to being able to properly cool and sell products according to the sales frequency and other conditions depending on the location where the vending machine is installed, a single vending machine can be made economical and can be installed in a variety of locations, and it also has a heat source. The operating rate of the system can also be adjusted depending on the installation location, resulting in energy savings.

Furthermore, since the size of the air opening provided in the chute is adjusted by moving the shield plate, space can be saved without the need for a separate wind speed control means.
