Description

[Detailed description of the invention] (a) Field of industrial application The present invention relates to a vending machine in which products can be loaded by opening the insulated door for loading the products.

(b) Conventional technology Conventionally, in vending machines that sell stored products after cooling them, when loading products, a method is used to prevent a large amount of cold air from flowing out of the storage compartment due to the opening of the insulated door. An opening for loading products is provided in the front of the storage in which the product storage column is installed, and a heat insulating door body that can be opened and closed for closing the front of the storage is provided, and a heat insulating door is provided to open and close the opening. A configuration is known in which a heat insulating door is opened to load products into the product storage column.
It is shown in the publication No.

In other words, in this conventional technology, an insulating door body is provided in the front of the storage compartment so as to be openable and closable, and only the portion corresponding to the front surface of the product input slot of a product storage column installed in the storage compartment is openable, and a heat insulation door body that opens and closes the opening is provided. A door is provided on the back side of the main door, and by opening the main door and opening the insulation door, only the part corresponding to the product input slot is opened to allow product loading, and cool air inside the storage can flow out. It is now possible to prevent

On the other hand, in a vending machine in which multiple spiral-type product storage columns are installed side by side in a storage compartment, the part into which products are inserted extends over almost the entire front surface of the product storage column, as shown in Figure 2. First, the opening 17 for loading the product must be opened wide. For this reason, in the case of this type of product storage column 4, a loading door 6 that can be opened and closed is provided on the front of each storage column 4, and the loading insulation door 18, which opens and closes the opening 17, is opened to load the product. Sometimes, only the loading door 6 of the product storage column 4 to be loaded is opened to minimize the outflow of cold air from the front surface of the other product storage columns 4 to the opening 17.

(c) Problems to be solved by the invention However, in both of these conventional techniques, since a gap is formed between the product storage column and the back surface of the insulating door body, it is difficult to load the products. When the heat insulating door is opened to open the opening, there is a problem in that cold air flows out from the opening through the gap 22 formed between the back surface of the outer periphery of the opening and the product storage column.

In view of the above, the present invention provides a vending machine that is provided with a cold air leakage prevention member to minimize the outflow of cold air from the opening opened during loading.

(d) Means for Solving the Problems The present invention provides a plurality of product storage columns arranged in a storage compartment, each having a product loading door that can be opened and closed in the front, and the loading door provided in the front of the storage compartment. In a vending machine comprising an insulated door with an opening that can be opened and closed, and a loading insulated door that opens and closes the opening of the insulated door, the back surface of the outer periphery of the opening of the insulated door and the product This configuration includes a cold air leak prevention member that contacts and seals the gap formed between the storage column and the storage column by closing the heat insulating door body.

(E) Effect Product storage columns with loading doors on the front are arranged side by side in the storage, and the front of the storage is provided with an insulated door body with an opening that allows the loading door to be opened and closed when the door is closed. Additionally, a loading insulation door will be provided to open and close the opening. A cold air leak prevention member is installed between the back of the outer periphery of the opening and the product storage column, which contacts and seals the insulated door when the door is closed, and the insulated door is opened while the insulated door remains closed during product loading. to open the opening. At this time, the gap between the back surface of the outer periphery of the opening and the product storage column is sealed with a cold air leak prevention member. Therefore, the loading doors of each product storage column are sequentially opened and closed to load the products.

(f) Embodiment Figures 1 and 3 to 6 show embodiments of the present invention. 1 is a vending machine for frozen food such as ice cream, and has an insulated box with an opening on the front. In the storage 3 formed by the body 2, a plurality of product storage columns 4 for storing products are arranged side by side on the left and right, and a cold air machine room 5 for storing a cooling unit is provided in the lower part. The storage column 4 has a substantially box-like shape with an opening for dropping the product on the lower surface and an opening for storing the product on the front surface, and the storage opening is provided with a loading door 6 for opening and closing the opening. ing. Also inside is a shaft 7 connected to the upper drive motor 8.
are provided above and below in the middle part, and a spiral 9 on which a product is placed between them is wound around the shaft rod 7. The shaft rod 7 is rotated by half a rotation by the drive motor 8 for each sale, and the product is discharged and dropped onto a guide chute 10 from the lowest end of the spiral 9. On the other hand, the front door body 11 constituting the front surface of the main body 1 has a product display section 12 at the top and a coin slot 1 at the middle section.
3. A selection button 14 and a sales outlet 15 are provided at the bottom. A heat insulating door body 16 is further provided behind the front door body 11 so as to correspond to the heat insulating box body 2 and can be opened and closed. The insulating box body 16 has an opening 17 so that the loading door 6 of the storage column 4 arranged in parallel in the main body 1 can be opened and closed even when the door body 16 is closed. A door 18 is provided so that it can be opened and closed. In addition, the sales port 1 is located at the bottom of the heat insulating door body 16.
5 and the guide chute 10 communicate with each other.
A sales door 21, which is opened and closed by a motor 20 during sales, is provided corresponding to this opening 19. Therefore, when loading products into the storage column 4, first open the front door 11, then open the insulation door 18 of the insulation door 16, open the loading door 6 of the required storage column 4, and then open the spiral 9.
Products can be inserted and stored in between.

The prevention member 23 is made of, for example, maltbrain, foamed polystyrene, etc.
A rectangular parallelepiped-shaped heat insulating material 24 is glued and fixed laterally to the upper and lower edges of the main body 1, and a rectangular parallelepiped-shaped heat insulating material 25 is filled and fixed in the vertical direction between the right side storage column 4 and the right side wall 1A of the main body 1. , the storage column 4 on the left side and a rectangular parallelepiped-shaped heat insulating material 26 that is filled and fixed in the vertical direction between the left side wall 1B of the main body. These four insulating materials 24, 25, 26 on the upper, lower, left and right sides are connected to the back surface of the outer periphery of the opening 17 of the insulating door body 16 and the storage column 4.
This closes the gap with the front of the refrigerator to prevent cold air from leaking inside the refrigerator. 27 and 28 are fixing members for fixing the storage column 4 to the main body 1, and when the heat insulating door body 16 is closed, the heat insulating material 24 is fixed to the fixing member 2, respectively.
7, 28.

Therefore, when loading products, only the opening when the loading door 6 of the storage column 4 that needs to be loaded is opened is the only place where the cold air leaks into the outside air, which is an extremely small minimum amount.

The cold air leak prevention member 23 can be modified in various ways; for example, the four sides may be integrated and provided on the back surface of the heat insulating door body 16, or it may be provided on the main body 1 side. At this time, various changes can be made as long as there is no problem in opening and closing the loading door 6 of the storage column 4.

(g) Effects of the invention As described above, the present invention provides a product loading door that can be opened when the insulating door is opened on the front of the product storage column, and also connects the back side of the outer periphery of the opening of the insulated door to the product storage column. A cold air leakage prevention member is provided between the opening and the product storage column to prevent a gap from forming between the back of the outer periphery of the opening and the product storage column. Since it is designed to prevent cold air from flowing out and outside air from flowing in through the opening between the product storage column and the product storage column, there is little outside air flowing in during product loading.
Not only can frost formation in the heat storage cabinet be prevented, but also product quality defects due to temperature changes in the storage cabinet can be prevented.
