Description

DETAILED DESCRIPTION OF THE INVENTION [Technical field to which the invention pertains] The present invention relates to a vending machine that is equipped with a cooling device or a heating device inside the machine and sells products such as canned drinks after being cooled or heated.

[Prior art and its problems]

Automatic fan parrots, which use in-flight cooling or heating equipment to cool or heat products such as canned drinks, are gaining widespread popularity. The cooling device for the vending machine will be described with reference to FIGS. 1 and 2. In the figure, 1 is the main body case where the front side of the vending machine is the entrance, 2 is the main body case that opens and closes the front side of the main body case 1,
and a door (not shown) having a vending switch, a product outlet, etc.; 4 is an interior of the refrigerator defined by a heat insulating wall within the main body case 1; 5 is a machine room adjacent to the lower part of the interior of the refrigerator 4; This is a product shelf that stores the products and includes a carry-out mechanism for carrying out the products one by one. Next, 11 is a cooler constituting a cooling unit of the cooling device, and 12 is a cooler 11 that cools the air inside the refrigerator.
This is a fan that circulates the air like an arrow. A plurality of fans 12 are installed in the horizontal direction of the refrigerator interior 4, in this case 4 fans (12
A to 12D) are installed in parallel. Reference numeral 13 denotes a condensing unit of the cooling device, which is composed of a compressor 14, a condenser 15, a fan 16, and the like. Ventilation holes are provided in the front door of the machine room 5 in which the condensing unit 18 is installed and in the rear wall of the main body case.

In the vending machine, a large number of noodle products are stored on the product shelf 6. Further, the cooling device is operated, and the products are cooled and kept cold by the air inside the refrigerator that is circulated through the cooler 11 by the fan 12 as shown by the arrow. Then, in response to a sales signal, the cooled product is carried out to the product outlet and sold.

By the way, in conventional vending machines, the amount of electricity consumed is extremely large because the cooling device is operated day and night and the air inside the warehouse is circulated through the cooler 11 by a large number of fans 12, and it is difficult to reduce the amount of electricity consumed. It was needed.

[Purpose of the invention]

This invention focuses on the fact that when the store is closed, such as at night, the amount of air circulated inside the store can be reduced, and the lights inside the store are turned off, making it possible to reduce power consumption without the need for particularly complicated operations. The purpose is to provide vending machines.

[Summary of the Invention] This invention operates by sensing ambient light and is provided with a photo switch that controls the operation of at least one fan among the plurality of fans, thereby controlling the amount of air circulation in the refrigerator when the store is closed at night, etc. One or more fans are stopped via the photoswitch during a time period when less air flow is required.

[Embodiments of the invention]

An embodiment of the invention will be described based on FIGS. 1 to 3. Note that FIG. 8 shows the electric circuit of the main part of the invention.

In the figure, a ventilation hole 2a is provided in the front side of the machine room 5 of the door 2 to allow a fan 16 to take in outside air for heat exchange with the refrigerant flowing through the condenser 15. 2
1 is a photoswitch installed facing the ventilation hole 2a. 12A to 12D are fans for circulating air in the refrigerator, and 12a to 12d are fan motors of the fans 12A to 12D, respectively. In this case, the operation of the two fan motors 12a and 12b is controlled via the photo switch 21. 22 is a thermostat for controlling the operation of the fan motor 16a of the fan 16 and the compressor 14 that constitute the condensing unit 18.

In the above configuration, when the store is opened during the day, the photo switch 21 closes its contacts in response to sunlight and store lighting, and all of the fan motors 12a to 12d are operated, and the fan 1
2 A to 12D circulate the air inside the refrigerator through the cooler 11, and the interior 4 of the refrigerator is powerfully cooled to correspond to the sales volume of the products. -When the store closes on a Monday night, sales of products stop, and the store lights are turned off and the store becomes dark. Sensing this decrease in the amount of light at night, the photoswitch 21 opens its contacts, and the fan motors 121 and 12b are stopped.

Accordingly, power consumption is reduced accordingly, and the interior of the refrigerator 4 is sufficiently cooled by the interior air circulated through the cooler 11 by the two fans 120 and 12D. The condensing unit 13 is efficiently operated via a thermostat 22 that is activated by detecting the temperature inside the refrigerator.

In the above example, we have explained the case where the machine is equipped with a cooling device to cool the products, but this address can also be applied to vending machines that have a heating device inside the machine and sell the products after heating them, and the same effect can be achieved. You can get it.

〔Effect of the invention〕

According to the present invention, a photoswitch that is activated by sensing ambient light is installed, and at least one fan among the plurality of fans is controlled via the photoswitch. Without requiring any operations, some fans are stopped when the store is closed at night, reducing power consumption, and products can be cooled and kept cold without any problems.
