DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cabinet for a vending machine for selling cans, bottles, cold goods containing paper packs, etc., and more particularly, to a mounting structure of a decorative frame with a gasket laid on the bottom front surface of an inner box. About.

[0002]

2. Description of the Related Art First, an overall configuration of a vending machine shown in FIG. In the figure, reference numeral 1 denotes a cabinet serving as an insulated housing, 2 denotes an outer door, 3 denotes an insulated inner door, and 4 denotes a cabinet 1.
Product storage racks (serpentine racks) housed in each room partitioned in the warehouse, 5 is a product unloading shooter,
Reference numeral 6 denotes a product outlet, and reference numeral 7 denotes a refrigerator installed in a machine room at the bottom of the cabinet 1. Although not shown in the drawing, a cooling / heating unit is provided at the bottom of the refrigerator behind the product unloading shooter 5. . Further, in order to seal the inside of the cabinet 1 with the heat-insulating inner door 3 closed, a gasket is laid along the periphery on the front surface of the inner box of the cabinet 1 facing the heat-insulating inner door 3.

In this case, especially for a gasket to be laid on the front surface of the bottom of the inner box, the gasket is not directly attached to the cabinet 1 for the following reason. It is designed to be removable. That is, in the structure of the bottom portion of the inner box shown in FIG. 3, a notch Q is formed in the front edge of the bottom of the inner box at a position corresponding to each chamber in the cabinet storage as shown in FIG. A refrigerant pipe P is provided between the machine 7 (see FIG. 2) and a cooler of a cooling / heating unit installed inside the refrigerator. In the figure, 1a is the side wall of the inner box made of sheet metal, 1b is the bottom plate, 1c
Is a front flange rising from the front edge of the bottom plate 1b, and 1d is an inner box bottom plate made of a heat insulating plate such as a foamed resin. By adopting such a refrigerant pipe structure, a gasket is integrated with the decorative frame 8 so as to be detachably attached to the bottom front surface of the inner box so as not to hinder the assembly of the refrigerant pipe P and the maintenance work of the refrigerator in the related art. I have to.

Here, the decorative frame 8 has a gasket 8b attached to the front surface thereof along a long base plate 8a made of a resin. After the cover 9 is screwed to the front surface of the bottom recessed portion Q, the decorative frame 8 with the gasket is applied from the front across the cover 9 with the cover 9 as a mounting seat for the decorative plate 8, and FIG. As shown in (b), the base plate 8a is fixed to the cover 9 by screws using the fastening screws 10. In addition,
In FIG. 4, reference numeral 1e denotes an outer box bottom plate of a cabinet containing the refrigerator 7.

[0005]

However, the above-described conventional mounting structure of the decorative frame 8 has the following problems in terms of assembling property and gasket sealing property. (1) In order to mount the decorative frame 8 with a gasket on the front surface of the bottom of the inner box of the cabinet 1, the cover 9 is attached to the front flange 1 a of the bottom plate in advance so as to cover the concave portion Q serving as the pipe passage of the refrigerant pipe P. Since the cover 9 is screwed and the cover 9 is affixed with the base plate 8a of the decorative frame 8 and screwed with the fastening screw 10, the number of screwing points and the number of working steps are large, Removal work is troublesome.

(2) Even when the decorative frame 8 is assembled,
Except for the part screwed to the front of the cover 9,
The base plate 8a of the decorative frame 8 is the front flange 1c of the inner box bottom plate.
And a gap corresponding to the thickness of the cover 9 remains between the plate surface of the flange 1c and the base plate 8a of the decorative frame 8 in this range. For this reason, the long decorative frame 8 bends in the longitudinal direction and easily undulates, and in the operating state in which the interior door 3 of the cabinet 1 is closed to keep the inside of the refrigerator cool, the decorative frame 8 is closed.
Of the gasket 8b and the door 3 in the cross-section due to the warpage of the gasket 8b, and also the problem that the cold air in the refrigerator easily leaks to the outside through the gap.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and has as its object to solve the above-mentioned problems and to provide a decorative frame with a gasket so that assembly to a cabinet is easy and high airtightness can be secured. It is an object of the present invention to provide a vending machine cabinet with an improved mounting structure.

[0008]

According to the present invention, there is provided, in accordance with the present invention, a heat-insulating inner door provided on a front surface of a cabinet serving as a heat-insulating housing having a product storage rack and a cooling / heating unit mounted therein. , And a vending machine cabinet equipped with an outer door and a decorative frame with a gasket facing the heat-insulating inner door on the bottom front surface of the inner box, wherein the decorative frame has a hook portion having a U-shaped cross section at its upper edge. And a gasket laid on the front surface of the base plate along the longitudinal direction of the base plate, and the hook portion is inserted into and engaged with the upper edge of the front flange of the inner box bottom plate, and The lower part of the plate is screwed and fastened to the cabinet (Claim 1). As a specific mode, the decorative frame is formed as an integrally molded product of a hard resin base plate and a gasket (Claim 2).

With this configuration, the number of screwing points, the number of parts, and the number of assembling steps can be reduced as compared with the conventional structure, and the work of assembling and removing the decorative frame can be performed easily. In addition, the base plate of the decorative frame covers the front surface of the recess through which the refrigerant tube passes, and its entire length is in close contact with the front flange of the bottom wall of the inner box.
