Description

  The present invention relates to a vending machine that sells products by cooling or heating products stored in a product storage device, and more particularly to a partition plate of a heat insulating wall that partitions the interior of the cabinet.

  Conventionally, as this type of vending machine, for example, as a structure of a partition plate, there is one of Patent Document 1 in which a front frame portion is formed of a steel plate member having an L-shaped cross section.

  FIG. 6 shows an exploded perspective view of a partition plate of a conventional vending machine described in Patent Document 1. In FIG. In FIG. 6, the partition plate 1 is attached to a partition plate body 2 of rigid urethane foam, an upper frame 3, a lower frame 4, a rear frame 5, a front frame 6, and a front frame 6 for reinforcing the partition plate body 2. A packing 7 is used.

  About the partition plate of the heat insulation wall of the vending machine comprised as mentioned above, the operation | movement is demonstrated below.

As shown in FIG. 6, the partition plate of the heat insulating wall covered with the upper frame 3, the lower frame 4, and the rear frame 5 of the partition plate body 2 is attached in a cabinet formed of rigid urethane foam. The storage rack is installed in each room in the room partitioned by a partition plate. As is well known, in such a configuration, the product stored in the product storage rack is kept cold by a cooler provided in the cabinet, or heated by a heater to be sold as a cold product or a hot product. In order to maintain the temperature of the cold product and the hot product, each chamber is partitioned into a heating chamber and a cooling chamber, and rigid urethane foam or vacuum heat insulating material is used as the partition plate body. In addition, the packing 7 attached to the front frame 6 closes the gap between the heat insulating door and the heat insulating door when the heat insulating door is closed.

FIG. 3 is a plan sectional view of a partition plate of a vending machine according to Embodiment 2 of the present invention.

  In FIG. 3, the hard resin material gasket 18 is provided with sandwiching portions 19 extending from both side surfaces toward the partition plate, and has a U-shaped shape so that both sides of the partition plate body 2 are sandwiched in the longitudinal direction. It has become.

  The operation of the vending machine partition plate configured as described above will be described below.

  When fixing to the partition plate body 2, a U-shaped hard resin material gasket 18 is inserted into the corner portion of the front surface of the partition plate and slides in the longitudinal direction. Since the sandwiching portion 19 is added to form a U-shape, the hard resin material gasket 18 can be inserted over the entire length of the partition plate without being easily removed.

  As described above, in the present embodiment, the cross-sectional shape of the hard resin material portion of the hard resin material gasket 18 is formed in a U shape, and the front surface portion of the partition plate is covered and brought into close contact with the front surface portion of the partition plate. The sealing property to the side surface portion is improved, the heating chamber 12 and the cooling chambers 13 and 14 in the cabinet 8 are sealed, and heat leakage between the heating chamber 12 and the cooling chambers 13 and 14 can be reduced. In addition, the gasket can be easily assembled because the front portion of the partition plate can be slid in the vertical direction in the gasket workability.

  The operation of the vending machine partition plate configured as described above will be described below.

  Since the constriction 26 is formed at the center of the hollow portion of the hard resin material on the soft resin material 24 side, the opening state of the sandwiched portions 27 and 28 spreads evenly and reasonably with the constriction 26 as the central axis. (Arrow E direction) Accordingly, the workability of incorporation into the partition plate body 2 can be further improved.

  As described above, in the present embodiment, by forming the constriction 26 in the hollow portion of the hard resin material gasket 25, it is possible to reduce the load applied to the corner portion of the hollow portion that is generated when the opening is widened. And cracking due to stress concentration can be prevented.

  As described above, the vending machine according to the present invention prevents heat conduction through the front frame parts and saves energy even when there is a temperature difference by cooling and heating the inside of the two containers sandwiching the partition plate. Therefore, the present invention can be applied not only to vending machines but also to cooling and heating devices having two adjacent rooms.
