Description

  The present invention relates to a vending machine that sells cans, bottles, and plastic bottle products, and more particularly to the structure of a heat insulating inner door disposed on the front surface of the cabinet.

  First, FIG. 2 shows the overall configuration of the vending machine described above. In the figure, 1 is a vending machine cabinet that becomes a heat-insulating housing, 2 is an outer door, 3 is a heat-insulating inner door, 4 is a product storage rack (serpentine-type product storage rack) mounted in the cabinet 1, A product carry-out shooter 6 is a product take-out port arranged at the lower part of the outer door 2. Although not shown in the figure, the cabinet 1 is equipped with a cooling / heating unit that cools or warms the stored goods, and the outer door 2 defines a display room. Equipped with a sample display stand.

  Next, the conventional structure of the heat-insulated inner door 2 employed in the vending machine is shown in FIGS. 3 (a) to 3 (c). As shown in the figure, the conventional heat insulating inner door 3 is constructed by assembling a steel plate front plate 3a and a rear plate 3b into a box shape through a joint member 3c, and injecting urethane resin or the like as a heat insulating material 3d therein to foam. A door plate (door body) is formed by molding, and a hinge bracket 7 and a door lock bracket 8 are attached to the left and right side edges of the door plate. 4 (see FIG. 2), a product carry-out port 3e with a shutter is provided so as to guide the product dispensed from 4 (see FIG. 2) to the product take-out port 6 of the outer door 2.

  On the other hand, recently, chlorofluorocarbons used in the resin foam molding process in the manufacture of the heat-insulated inner door have been regulated due to environmental problems. In addition, when recovering resources by disassembling a vending machine that is no longer needed, the inner door 3 having a heat-insulating structure in which resin is foam-molded is bonded to the steel plates 3a and 3b and the heat insulating material (foamed resin) 3d. Therefore, there is also a problem that it takes time to separate the steel material and the foamed resin.

Therefore, as a countermeasure against the above problem, a resin board in which the heat insulating material of the heat insulating inner door is formed into a plate shape in advance instead of foaming of resin is adopted, and a steel plate front plate, a reinforcing frame, and a product carrying are used on this board. A combination of an exit shutter, a shutter frame, and the like to form a door plate of a heat insulating inner door is known (see, for example, Patent Document 1).
JP 2002-216225 A

  According to the structure of the heat insulating inner door disclosed in Patent Document 1, since the resin board is adopted as the heat insulating material, there is no need for a resin foam molding process using Freon, and this heat insulating inner door is disposed of. In this case, there is an advantage that the metal material and the resin material can be easily separated, but there is a problem that the manufacturing cost of the door is increased due to the assembly structure.

  That is, in order to attach the shutter and shutter frame of the product outlet to the door plate, the entire front area of the resin board is covered with a metal plate (steel plate). For this reason, the amount of steel plate used for the heat insulating door is increased and the cost is increased. In addition, when the area covering the door plate with a metal plate having high heat conductivity is increased, there is a problem that the heat insulating performance as the heat insulating door is lowered correspondingly and the heat loss of the vending machine is increased.

  The present invention has been made in view of the above points, and its object is to solve the above-mentioned problems, and to ensure high heat insulation performance with a low cost and simple assembly structure, and to improve the convenience of product display. The purpose is to provide an insulated door for a vending machine.

In order to achieve the above object, according to the present invention, in a vending machine provided with a heat insulating inner door and an outer door on the front surface of a cabinet that becomes a heat insulating casing in which a product storage rack is mounted in a warehouse,
The inner door is composed of a door plate made of a resin heat insulating board, and a metal outer frame fixed to the four sides around the door plate and attached with a hinge fitting and a door lock. A product outlet that leads to a product outlet of the outer door is arranged in the lower part (Claim 1), and specifically, it is configured in the following manner.

  (1) A cover sheet made of resin is applied to both the front and back sides of the door plate to protect the door plate, and the face sheet is printed or written on a blackboard or white board. Thus, a function as a display board for displaying is provided (claim 2).

  (2) The product frame outlet shutter frame is fixed to the outer frame disposed on the lower side of the door plate to ensure mechanical strength (Claim 3).

  (3) A display stand for product samples that protrude toward the display room of the outer door is installed in the middle position on the front side of the door plate, and the product samples are displayed here in the display room.

  (4) In the preceding paragraph (3), the display stand for the product sample is constructed between the outer frames arranged on the left and right side edges using the outer frame of the door plate (Claim 5).

  According to the above configuration, the amount of steel used for the door is less than that of the heat insulating inner door disclosed in Patent Document 1, thereby reducing the cost and improving the heat insulating performance as well as reducing the weight of the door. A function as a display board can be provided by printing or the like using a face material sheet made of resin (for example, PET resin) adhered to both front and back surfaces of the material board.

  In addition, a display stand for product samples is installed on the front face of the door plate, so that the structure of the display room has been simplified by omitting the middle door that was previously provided on the back of the outer door and supported the product display stand in the display room. Can be planned.

  As described above, the heat-insulated inner door of the present invention is made of a metal plate for reinforcement in which a hinge plate and a door lock are attached to a door plate having a resin heat insulating board as a substrate and fixed to four sides around the door plate. A specific embodiment of the present invention will be described based on the embodiments shown in FIGS. 1 (a) to 1 (c).

  In other words, the heat insulating inner door 3 in the illustrated embodiment uses a heat insulating board 9 in which a resin having low heat conductivity is previously formed into a plate shape as a door plate, and pastes face sheet 9a, 9b such as PET resin on both front and back surfaces. After that, a reinforcing outer frame 10 in which the channel steel materials 10 a to 10 d are combined is fitted to the four surrounding sides and fixed by the fixing screw 11. Further, with respect to the door plate, hinge metal fittings 7 and door lock metal fittings 8 are attached to the outer frames 10a and 10b arranged on the left and right side edges, and an outer frame 10d arranged on the lower part of the door plate. The shutter frame of the product outlet 3e is attached and screwed to the front frame (the width of the front side is made wider than the outer frame arranged on the side).

  Furthermore, in this embodiment, a display stand 12 for displaying the product sample 13 is installed at the middle position on the front surface of the door plate, and the display stand 12 protrudes toward the display chamber of the outer door 2 (see FIG. 2). . In addition, this display stand 12 is connected and supported by outer frames 10a and 10b arranged at the left and right side edges of the door plate at both left and right ends.

  With this configuration, the above-mentioned display stand installed on the front side of the heat-insulating inner door 3 without the middle door (see FIG. 2) provided on the back side of the conventional outer door 2 and supporting the display stand of the product sample is omitted. 12 is used to display the product sample 13 in the display room of the outer door, and the product sheet advertisement as shown by the reference numeral 14 here is used as the display panel with the face material sheet 9a adhered to the front surface of the door plate of the heat insulating inner door 3. It can be used as a display board that can be printed, pasted, or filled with characters such as a blackboard or whiteboard.
