Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is equipped with a product pen rack, such as a serpentine type or slanted shelf type product pen rack, in which products are loaded into the rack from an upper slot using gravity and stored in the rack. Regarding the improvement of refrigerated or heated vending machines,
The purpose of the present invention is to provide a useful vending machine that skillfully prevents cold or warm air from escaping unexpectedly when loading products, prevents heat loss, and saves energy. shall be.

Vending machines that sell products such as cold drinks or hot drinks are equipped with refrigeration or heating devices, and the main body case also has an insulating structure to prevent heat loss during operation. We are trying to

The general conventional structure of such a vending machine is shown in FIGS. 1 and 2.

In the figure, 1 is the main body case of the vending machine, and the main case 1 is composed of an outer box 3 consisting of a heat insulating wall 2 and a front door 4, and the front door 4 further has an outer door 4a and a heat insulating structure. The inner door 4b has a double door structure and is attached via a hinge 5 so that it can be opened and closed.

On the other hand, inside the outer box 3, a product pendlack 6, which is illustrated as a serpentine type, is housed, for example.

7 is an unloading mechanism installed at the lower unloading end of the pend rack 6.

Further, the front door 4 is provided with a product take-out port 8 so as to be linked to the delivery end of the product pen rack 6, and various devices 9 such as a coin mechanism and a relay are installed in the inner space of the outer door 4a.

The inside of the outer box 3 is operated in combination with the condensing unit 10, or is cooled by the cooler 11, or a heater is installed in place of the cooler 11 or in conjunction with the cooler 11. It is heated.

The vending operation of such a vending machine is well known and will be omitted here.

By the way, the loading operation of replenishing the product pen rack 6 with the products 12 is generally performed by a traveling service worker called a route man as follows.

That is, as shown in FIG. 2, first open the front door 4 to expose the front of the outer box 3, and then open the upper input slot 6 of the rack 6 as shown by arrow A.
The products 12 are successively put into a and stored.

As described above, in the conventional structure, the front opening of the outer box 3 is configured to be closed by the heat-insulating inner door 4b of the front door 4, and loading the product into the product pen rack 6 is performed by opening the front door 4. It needs to be done in good condition.

Therefore, each time a product is loaded, the front surface of the outer box 3 is completely opened, and cold or hot air inside the refrigerator flows out of the refrigerator, causing a rapid increase or decrease in the temperature inside the refrigerator.

As a result, heat loss increases, power consumption increases, and operating costs increase.

In addition, since the front door 4 is opened each time, a large working space is required and the workability is also poor.

Additionally, the front panel □4, which is opened during loading operations, exposes the various devices inside, especially the coin mechanism, each time, which has the inconvenience of actively giving unscrupulous route personnel an opportunity to engage in fraud over sales proceeds. .

In view of this, the present invention aims to provide an advantageous vending machine that can save energy by preventing heat loss during product loading through a clever configuration. The door is provided with a small window that allows products to pass through at a location opposite to the product inlet of the product pen rack stored in the warehouse, and an outer door facing the small window can be opened and closed independently from the front. A distant relative is established by installing and configuring a possible small door.

Next, the configuration and effects of the present invention will be explained in detail based on illustrated embodiments.

In FIGS. 3 to 5, the same reference numerals as in FIGS. 1 and 2 indicate the same members.

According to the present invention, a small window 13 through which products 12 can pass is cut out and opened in the upper region of the inner door 4b of the front door 4 having a heat-insulating structure.

This small window 13 is located in the upper part of the product slot 6a which is housed in the outer box 3, for example in the case of a serpentine rack as shown in the figure.
The opening is defined at a position opposite to the product insertion opening 6a of the product pen rack 6, which is provided with a product pendant rack 6 and stores products 12 into the rack in a gravity-drop manner.

Further, the small window 13 is provided with a door cover 14 which serves as a flapper whose upper side is pivoted and is installed so as to be openable and closable as shown by arrow B.

The small window 13 is always closed by the door cover 14.

Further, a small door 15 is installed on the outer door 4a opposite to the small window 13, which can be opened and closed independently from the front as shown by arrow C with the outer door 4a closed.

Note that 15a is a locking mechanism for the small door, which is locked with the outer door 4a.

Further, the small door 15 can be configured to also serve as a product display board.

Product loading in the above configuration is performed as follows.

First, only the small window 15 in the front door 4 is opened.

As a result, as shown in FIG. 4, the small window 13 of the inner door 4b can be seen inward from the front.

In this state, the products 12 are successively introduced and stored into the product pen rack 6 while pushing open the door cover 14 through the small window 13 as shown by arrow A.

As is already clear from the explanation of this operation, during the product loading operation, the front of the outer box 3 remains closed by the inner and outer doors of the front door 4 and is not opened.
Cold or hot air inside the refrigerator does not flow out of the refrigerator.

Moreover, even when the small door 15 is open, the small window 13 is closed by the door cover 14, so that good heat insulation performance can be maintained.

As a result, heat loss inside the refrigerator during product loading, which was a problem in the conventional configuration, is prevented, and energy savings such as reduction in power consumption can be improved.

In addition, it is only necessary to open the small door 15 during loading work, which requires only a small work space and improves work efficiency.

Furthermore, the outer door itself of the front door 4 can be kept locked during product loading, and the coin knock on the inside will not be exposed unnecessarily, preventing fraudulent sales proceeds from malicious route personnel. Can be suppressed.

The vending machine with the above configuration is not limited to the serpentine type product pen rack as shown in the example shown, but can be applied to all product pen racks in which products are loaded and stored from the product slot at the top using gravity falling. Can be applied.

As described above, the present invention has the effect of skillfully preventing heat loss inside the refrigerator when loading products, improving energy saving such as saving power consumption, and in addition, improving loading work. You can improve your sexuality.

In addition, it is possible to provide a vending machine with high practical value, such as preventing the coin knocking from being unnecessarily exposed during the loading operation and suppressing fraudulent activity with respect to sales proceeds.
