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 which sells canned and bottled beverage products by mounting a serpentine type product storage rack in a refrigerator, and more particularly to a heat insulating inner door having a vertically divided structure. It relates to the structure of the gasket attached to.

[0002]

2. Description of the Related Art First, FIG. 3 shows the overall structure of a vending machine to which the present invention is applied. In the figure, 1 is a cabinet body serving as a heat insulating housing, 2 is a front outer door thereof,
Reference numerals 3 and 4 denote an upper heat-insulating inner door (commodity loading door) and a lower heat-insulating inner door, which are divided into upper and lower parts, 5 denotes a serpentine-type product storage rack mounted in the cabinet of the cabinet body 1, and 6 denotes a top of the product storage rack 5. A product insertion opening 7 opened on the front surface, a product outlet 7 provided on the outer door 2, and an upper insulated inner door 3 is an outer door 2.
To open and close together with the outer door. Although not shown, a cooling / heating unit for keeping the product cold (cold product) or heating it (hot product) is provided in the cabinet of the cabinet body 1.

[0003] With such a configuration, when replenishing merchandise to the merchandise storage rack 5, the lower heat-insulating inner door 4 is kept closed and the outer doors 2, 2 are closed.
The upper heat-insulating inner door 3 is opened, and a product (can, bottle product) is charged into a product input port 6 which is open at an upper portion of a front surface in the refrigerator. on the other hand,
When a sales order is given in the sales state, the product storage rack 5
The product dropped from the container is the product delivery door 4a of the inner insulation door 4.
It is well known that the user pushes open and rolls out to the product outlet 7.

Further, in order to prevent cold air or warm air inside the cabinet body 1 from escaping outward, the space between the peripheral edges of the heat insulating inner doors 3 and 4 and the cabinet body 1 is hermetically closed by a gasket. Further, in order to seal a gap between the upper heat-insulating inner door 3 and the lower heat-insulating inner door 4 in a state where the heat-insulating inner door having a vertically divided structure is closed, as shown in the drawing, Gaskets 8, 9 are laid at the lower end of the heat-insulating inner door 3 and the upper end of the lower heat-insulating inner door 4, respectively, and the gaskets 8 and 9 are abutted to close the gap between the divided door mating surfaces.

Next, FIGS. 4 and 5 show the structure of a gasket used for a conventional split heat-insulating inner door. That is, the gaskets 8, 9 mounted on the end surfaces in accordance with the upper heat-insulating inner door 3 and the lower heat-insulating inner door 4 protrude from triangular underframe portions 8a, 9a made of a hard resin material and the inclined surfaces of the underframe portions. In this configuration, the packing portions 8b and 9b made of a soft resin material having a semicircular cross section are integrally formed, and the underframe portions 8a and 9a are arranged in front and rear so that their inclined surfaces face each other at substantially the same height, and the upper portions are respectively formed. It is attached to the lower end surface of the heat insulating inner door 3 and the upper end surface of the lower heat insulating inner door 4. 8c and 9c are fin-shaped packings made of a soft resin material.

When the upper heat-insulating inner door 3 is closed in such a configuration,
As shown in FIG. 5, the packing portion 8b of the gasket 8 abuts against the inclined surface of the underframe 9a of the gasket 9 mounted on the lower heat-insulating inner door 4, and the packing 9b of the gasket 9 is underframe of the mating gasket 8. The gap between the divided doors is closed by contacting the inclined surface of the portion 8a.

[0007]

However, the conventional gasket structure described above has the following problems in terms of the assemblability of the heat-insulating inner door and the sealing function. (1) When one or both of the divided inner doors 3 and 4 are slightly displaced in the vertical direction from the reference position in the closed state of the door shown in FIG. 5, the packing portions 8a and 9a of the gaskets 8 and 9 are removed.
Can not be tightly attached to the mating frame inclined surface of the mating gasket, resulting in poor sealing performance. Conversely, the triangular cross-section of the frame (hard material) directly overlaps and bites, making it difficult to open and close the door. Such troubles occur.

For this reason, in the vending machine assembling process shown in FIG. 3, it is necessary to strictly control the assembling accuracy of the doors 2, 3, and 4. Further, it is necessary to repeatedly open and close the door at the location of the vending machine. If the door is rattled due to the wear of the hinge fitting, etc., this causes the gaskets 8 and 9 to easily cause the above-described problem. (2) In the operation state in which the inside of the cabinet is kept cool, dew condensation occurs at the joint of the gaskets 8 and 9 due to the temperature difference between the inside and the outside of the cabinet. There is a problem that the door hangs down on the surface of the heat-insulating inner door and wets the door surface, so that dust or the like adheres and the door becomes dirty.

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 mating surface of a vertically divided type heat-insulated inner door without being affected by assembly accuracy of the heat-insulated inner door and rattling. To provide a vending machine cabinet improved so that the gasket attached to the gasket can be stably sealed, the door can be opened and closed smoothly, and at the same time, condensation water generated in the gasket can be prevented from flowing down. is there.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the embodiments shown in FIGS. In the drawings of the embodiment, members corresponding to FIGS. 4 and 5 are denoted by the same reference numerals. That is, in the configuration of the illustrated embodiment, the underframe 8a of the gasket 8 attached to the lower end surface of the upper heat-insulating inner door 3 is located on the front side of the door plate and the gasket 9 attached to the upper end surface of the lower heat-insulating inner door 4. The underframe 9a is mounted on the rear side of the door plate,
A step h is set between the two in the vertical direction (this step h is determined in consideration of the door assembly error and the door rattling). The backlash in the direction is absorbed, and a sufficient space is left between the underframe 8a of the gasket 8 and the underframe 9a of the gasket 9 with the door 3 closed (see FIG. 2). Thereby, opening and closing of the heat insulation inner door 3 can be performed smoothly without being affected by the backlash of the door.

The packing portion 8b of the gasket 8 is formed so as to protrude downward from the inclined surface of the underframe portion 8a, and the packing portion 9b of the gasket 9 is formed at the underframe portion 9a.
a, the packing portion 8a of the gasket 8 and the packing portion 9b of the gasket 9 overlap with each other in the front and rear direction when the door is closed as shown in FIG.
The gap between the first and fourth is closed airtightly.

Further, in the illustrated embodiment, the lower heat-insulating inner door 4
A dam 9d is formed at the front of the underframe 9a of the gasket 9 attached to the damper 9a by using a fence rising from the front edge as a dam. With this configuration, the dew water generated on the packing surface of the gasket in the cold storage operation state in the refrigerator drops and accumulates on the dam portion 9d, where it evaporates naturally. Therefore, unlike the conventional case, dew condensation water does not flow down on the surface of the door 4 and does not stain the door surface.

[0016]

As described above, according to the structure of the present invention, the following effects can be obtained. (1) According to the first aspect, a step in the height direction is set between the frame portions of the gaskets mounted on the upper and lower heat insulating inner doors, and the packing parts are front and rear with the heat insulating inner door closed. The upper insulation inner door and the lower insulation inner door are not affected by assembly errors of the heat insulation inner door arranged on the front of the cabinet and vertical backlash, etc. Can be reliably sealed, and the heat insulation inner door can be smoothly opened and closed by preventing interference between the frame portions made of the hard material of the gasket.

(2) Further, according to the second aspect, a dam portion for storing dew condensation water generated in the packing portion is formed in the underframe portion of the gasket attached to the lower heat insulating inner door, thereby keeping the inside of the refrigerator cool. The problem of the conventional structure that the dew water generated on the surface of the packing portion of the gasket during operation hangs down on the surface of the inner door as it is and contaminates the door surface can be solved.
