[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a vending machine in which a cooling / heating unit with a fan is incorporated in a cabinet of a main body cabinet, and products stored in a product storage rack are kept cold or heated for sale.
[0002]
[Prior art]
First, FIG. 2 and FIG. 3 show the configuration of a hot and cold vending machine that is an object of the present invention. In the figure, 1 is a main body cabinet of a vending machine as a heat-insulating housing, 2 is an outer front door, 3 is a heat-insulating inner door, and a product storage rack (for example, a serpentine-type product storage rack) is housed in the main body cabinet 1. 4. In addition to the product carry-out shooter 5, a cooling and heating unit 6 with a fan is installed at the bottom of the cabinet so that the product stored in the product storage rack 4 can be refrigerated or refrigerated.
[0003]
Here, the cooling and heating unit 6 has a structure in which a cooler (evaporator for a refrigerator) 6c and a heater 6d are incorporated in a wind tunnel 6b provided with a fan 6a, and is connected to the rear end of the wind tunnel 6b. A ventilation duct 7 is installed on the rear panel of the cabinet 1. Reference numeral 8 denotes a refrigerator condensing unit installed in the lower machine room of the main body cabinet 1.
[0004]
The selling operation of the vending machine having such a configuration is well known, and the product (can product) carried out from the product storage rack 4 based on the sales instruction rolls on the slope of the shooter 6 and is provided on the heat insulating inner door 3. The product carry-out door 3a is pushed open and sent to the product take-out port 2a of the outer door 2. Here, when selling cold merchandise, the refrigerator is operated, and the cool air cooled by heat exchange with the cooler 6c is circulated and blown in the cabinet by the fan 6a as indicated by arrows to keep the merchandise cool. On the other hand, when selling hot merchandise, the heater 6d is energized to heat the air in the cabinet, and the warm air is circulated into the cabinet to heat the merchandise. In addition, the cool air and warm air blown out upward in the cabinet flow through the region of the product storage rack 4, and then are sucked into the ventilation duct 7 and returned to the cooling and heating unit 6.
[0005]
Next, FIG. 4 shows a mounting structure of the ventilation duct 7 in a conventional vending machine. In addition, the code | symbol 1a is a back panel of the main body cabinet 1 (refer FIG. 3 ) made as a heat insulation housing | casing in the figure . That is, the ventilation duct 7 is obtained by sheet-metal processing a thin steel plate into a U-shaped cross section, and flanges 7a are formed on both left and right sides, and the flange 7a is positioned on the plate surface of the back panel 1a. Above, both are fixed by screwing with a tapping screw 9. Reference numeral 7 b denotes a window hole that communicates with the rear end face of the cooling and heating unit 6.
[0006]
[Problems to be solved by the invention]
By the way, the conventional mounting structure of the ventilation duct has the following problems in terms of assembly workability. That is, in order to fix the ventilation duct 7 to the rear panel 1a of the cabinet, it is necessary to perform screw positioning at 4 to 6 positions per ventilation duct after positioning the duct and aligning the screw holes. In addition, in a can beverage vending machine, the inside of the cabinet is usually divided into three product storage rooms, and ventilation ducts are laid for each room. Therefore, the screws required to install the ventilation ducts per vending machine There are 12 to 18 stop points, and many man-hours are required. In addition, the entrance of the product storage room partitioned into the cabinet of the main body cabinet is narrow enough to allow the worker's body to barely enter, especially in vending machines where the depth of the product storage room is deep, installation work of ventilation ducts However, improvement of workability is strongly desired as a request from the field.
[0007]
The present invention has been considered in view of the above points, and its purpose is to improve a vending machine that can be easily and efficiently installed when installing a ventilation duct for ventilation inside the cabinet of the main body cabinet, In particular, it is to provide a mounting structure for a ventilation duct.
[0008]
[Means for Solving the Problems]
In order to achieve the above object, according to the present invention, a cooling / heating unit with a fan is installed at the bottom of the cabinet of the main body cabinet on which the product storage rack is mounted, and the rear surface of the cabinet cabinet is connected to the wind tunnel of the unit. In a vending machine in which a ventilation duct for air inside the cabinet is installed on the panel, the ventilation duct shall be installed as follows.
[0009]
1) ventilation duct is processed into a U-shaped section, has a ventilation window hole to the lower, the upper center of the ventilation duct engaging claw of the hook shape toward the back side, the lower edge of the ventilation window holes in the lower part A screw seat is provided toward the back side, and a square hole and a screw hole are formed on the back panel side so as to face the locking claw and the screw seat, and the locking claw is hooked into the square hole. Screw between the screw seat and the screw hole to fix the ventilation duct in place on the back panel.
[0010]
2) In the preceding paragraph 1 ) , the locking claw and screw seat are formed by cutting and raising from the front center to the back side of the ventilation duct.
In this configuration, when the ventilation duct is fixed to the rear panel of the main body cabinet, the locking claw at the upper part of the duct is hooked into the square hole on the panel side and positioned, and then the lower part is screwed. Troublesome screwing points are halved compared to the conventional one . Moreover, by forming the latching claw and screw seat by cutting and raising from the center of the duct plate surface, the structure is simple and only two installation points are required, and the ventilation duct can be incorporated efficiently in a short time. .
[0011]
DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below with reference to the drawings. In addition, the same code | symbol is attached | subjected to the same member corresponding to FIG. 4 in the figure of each Example.
[ Embodiment ] FIGS. 1 (a) to 1 (c) show an embodiment corresponding to claims 1 and 2 of the present invention. In this embodiment, a ventilation duct having a U-shaped cross section is processed. A hook-shaped locking claw 7c is cut and raised at the upper center toward the back side, and a screw seat 7d is cut and raised at the lower side from the lower edge of the ventilation window hole 7b toward the lower side. Screw holes are drilled in. On the other hand, on the plate surface of the rear panel 1a of the main body cabinet 1 facing the locking claw 7c and the screw seat 7d, a square hole 1b for hooking the locking claw 7c in advance according to the installation position of the ventilation duct 7, and The screw hole 1c is processed.
[0012]
And in the assembly process which inserts the ventilation duct 7 in the store | warehouse | chamber of the main body cabinet 1 and attaches it to the back panel 1a, after first positioning the ventilation duct 7 by hooking the latching claw 7c of a duct in the square hole 1b of a panel, The tapping screw 9 is screwed and fixed between the screw seat 7d and the screw hole 1c on the other side by a screwdriver 10. As shown in FIG. 1C, the left and right edges of the ventilation duct 7 are brought into close contact with the plate surface of the rear panel 1a without leaving a gap in the state where the locking claw 7c is hooked in the square hole 1b. The front end of the locking claw 7c can be folded slightly deeper toward the front side, and the variation in dimensions can be absorbed by utilizing the spring property.
[0013]
【The invention's effect】
As described above, according to the configuration of the present invention, the work for installing the ventilation duct in the cabinet of the main body cabinet is easier to position the ventilation duct than the conventional mounting structure of the screw method, and The number of man-hours can be reduced, so that the workability in the assembly process can be greatly improved. For example, the ventilation duct can be efficiently installed in a short time.
