Technical Field

The present invention relates to a vending machine equipped with a condensing unit of a refrigerator, the vending machine including an exhaust port cover for closing an exhaust port formed in a back surface of the vending machine, the exhaust port being used for discharging heat from the condensing unit of the refrigerator.

Background

The automatic vending machine equipped with the condensing unit of the refrigerator is configured to include a main body cabinet having an opening on the front surface and a front door which closes the opening on the front surface of the main body cabinet and is openable and closable. The main cabinet is configured as a heat-insulating casing by arranging heat-insulating materials formed by polyurethane foam on the inner sides and the bottom wall of an upper plate, left and right side plates and a back plate which form an outer box made of steel plates, and the heat-insulating casing forms a commodity storage. A commodity storage rack for storing commodities is disposed in a commodity storage compartment surrounded by a heat insulating material in the main body cabinet, and a cooling/heating unit having an evaporator, an in-compartment fan, a heater, and the like is disposed at a lower portion of the commodity storage rack, and the cooling/heating unit cools or heats commodities stored in the commodity storage rack and stores the commodities in a cold state or a hot state.

The lower part of the bottom wall of the main cabinet body forming the commodity storage is formed into an equipment chamber. A condensing unit of a refrigerator that forms a refrigeration cycle with the evaporator of the cooling/heating unit is disposed in the equipment room. The condensing unit of the refrigerator includes a compressor, an aluminum finned tube condenser, an outdoor fan, an expansion valve, and the like, and the condenser disposed outside the commodity storage and the evaporator disposed inside the commodity storage are connected by a refrigerant pipe via the expansion valve.

The air sucked through an air inlet provided near the lower edge of the front door is ventilated into the equipment room by the operation of the external fan, and after the compressor and the condenser are cooled, the heat generated by the compressor and the condenser during the operation of the refrigerator is dissipated from a heat-dissipating exhaust port formed in a back plate of the vending machine. The exhaust port is formed as an opening of a rectangular shape and is provided with an exhaust port cover for dissipating heat generated from the compressor and the condenser and preventing entry of vermin, rodents, etc. from the outside. The exhaust port cover is formed in a size corresponding to the exhaust port by assembling a plurality of wires in a lattice shape, spot welding, and plating, and is fixed to the edge of the exhaust port of the back plate by screws so as to cover the exhaust port.

The exhaust port cover formed by assembling a plurality of wires in a lattice shape can prevent entry of pests, rodents, mammals and the like, but cannot prevent penetration of rain and snow. In the case where rain and snow penetrate into the equipment room of the vending machine and adhere to the compressor or the like of the condensation unit of the refrigerator, there is a possibility that the function of the condensation unit of the refrigerator is lowered, and in the case where rain and snow adhere to the electrical components provided in the equipment room, there is a possibility that electric leakage occurs. In order to solve such a problem, an invention disclosed in patent document 1 as shown in fig. 9 is known.

Fig. 9 shows an automatic vending machine of a conventional apparatus disclosed in patent document 1, fig. 9 (a) is a rear view of a main body cabinet of the automatic vending machine, fig. 9 (b) is a perspective view of an exhaust cover, and fig. 9 (c) is a cross-sectional view of the exhaust cover. As shown in fig. 9 (a), a rectangular air outlet 104 is provided in a portion of the back plate 101 of the main body cabinet 100 facing the equipment room 103, and a plate-shaped air outlet cover 105 is detachably provided in the air outlet 104 in a form of being fixed to an edge portion of the air outlet 104 of the back plate 101 by screws.

A plurality of exhaust holes 106 are formed in the plate surface of the exhaust cover 105 (see fig. 9 c), and an exhaust cover 107 having a downward opening is provided in the exhaust holes 106. The exhaust cover 107 is similar to a room cover of a ventilation fan, and includes an eaves portion covering the upper and front sides of the exhaust hole 106 and side portions covering the left and right sides of the exhaust hole 106, and the eaves portion and the left and right side portions form a downward opening. The exhaust hood 107 is formed by punching a slit at a portion of the plate-shaped exhaust cover 105 corresponding to the lower edge of the exhaust hole 106. The exhaust hole 106 is formed as a result of press working of an exhaust cover 107 with respect to the plate-shaped exhaust cover 105, and the upper portion, the front surface, and the left and right side portions of the exhaust hole 106 are shielded by the exhaust cover 107. By providing the exhaust cover 107 in the exhaust hole 106 in this manner, heat generated by the compressor and the condenser provided in the equipment room can be dissipated from the exhaust hole 106 through the downward opening of the exhaust cover 107, and rain, snow, and the like can be prevented from penetrating into the equipment room.

The exhaust hole 51 is formed as a result of press working of the exhaust cover 52 with respect to the plate-shaped exhaust port cover 5, and the upper portion, the front surface, and the left and right side portions of the exhaust hole 51 are shielded by the exhaust cover 52.

Further, 3

engaging claws

5a, and 5a protruding downward from the lower edge of the air outlet cover 5 are formed on the lower edge. The

engagement claws

5a, and 5a are formed corresponding to slit-shaped engagement grooves 1e0, 1e0, and 1e0 (see fig. 1 (b)) formed in the base 1e and perforated at positions near the exhaust port 50. Screw through

holes

A plurality of (13 layers in the vertical direction and 4 rows in the horizontal direction) exhaust holes 61 (see fig. 3 a) similar to the exhaust holes 51 of the exhaust cover 5 are also formed in the plate surface of the exhaust cover 6, and an exhaust cover 62 is also provided in the exhaust holes 61. Here, the exhaust cover 62 includes a brim 62a covering the lower and front sides of the exhaust hole 61 and left and right side surfaces 62b, 62b covering the left and right sides of the exhaust hole 61, and an upward opening 62c is formed by the brim 62a and the left and right side surfaces 62b, 62 b.

Further,

attachment pieces

63, 63 bent outward in a form having a step higher than the plate surface of the exhaust port cover 6 are provided at both left and right ends of the exhaust port cover 6. Screw through

holes

6b, 6b identical to the screw through

holes

5b, 5b formed in the upper portions of the left and right sides of the plate surface of the exhaust port cover 5 are formed in the

attachment pieces

63, 63.

In order to assemble the exhaust covers 5 and 6 to the main body case 1, first, the exhaust cover 6 is placed on the base 1e in such a manner that the plate surface of the exhaust cover 6 on which the exhaust hole 61 with the exhaust cover 62 is formed is fitted into the cavity forming the exhaust port 50 from the back surface side of the main body case 1 and the left and

right attachment pieces

63 and 63 of the exhaust cover 6 are brought into contact with the rear side leg pieces 1f1 and 1g1 of the reinforcing

members

1f and 1 g. In this case, the

screw insertion holes

6b and 6b formed in the left and

right attachment pieces

63 and 63 of the exhaust port cover 6 are substantially opposed to the screw holes 1f0 and 1g0 of the leg pieces 1f1 and 1g1 inserted in the rear side of the reinforcing

members

1f and 1 g.

Then, the engaging

claws

5a, and 5a projecting downward from the lower edge of the air outlet cover 5 are inserted into the engaging grooves 1e0, 1e0, and 1e0 formed in the base 1e, and the plate surface of the air outlet cover 5 is superposed on the left and right mounting

pieces

63 and 63 of the air outlet cover 6. In this case, since the screw through

holes

5b and 5b formed in the upper portions of the left and right sides of the air outlet cover 5 are substantially opposed to the screw through

holes

6b and 6b formed in the left and

right attachment pieces

63 and 63 of the air outlet cover 6, the air outlet covers 5 and 6 are assembled to the main body case 1 in a state where the air outlet 50 is closed by screwing screws (not shown) into the screw holes 1f0 and 1g0 of the leg pieces 1f1 and 1g1 inserted through the rear sides of the reinforcing

members

1f and 1g through the screw through

holes

5b and 5b of the air outlet cover 5 and the screw through

holes

6b and 6b of the air outlet cover 6.

In this way, in a state where the air outlet covers 5 and 6 are assembled to the main body cabinet 1, the air outlet hole 51 provided in the air outlet cover 5 and the air outlet hole 61 provided in the air outlet cover 6 are configured to be shifted in position from each other so as to partially overlap in the front-rear direction. That is, fig. 4 is a rear view of the exhaust covers 5 and 6 stacked in the front-rear direction as viewed from the back surface side, and as can be seen from fig. 4, the positions of the plurality of exhaust covers 52 provided to the exhaust cover 5 and the plurality of exhaust covers 62 provided to the exhaust cover 6 are shifted from each other so as to partially overlap each other in the front-rear direction. In fig. 4, the exhaust holes 51 provided in the exhaust cover 5 and the exhaust holes 61 provided in the exhaust cover 6 are not visible, but as is clear from the above description, the exhaust holes 51 and 61 are positioned to coincide with the exhaust cover 52 and the exhaust cover 52.

Fig. 5 shows a side sectional view of the air outlet covers 5 and 6 having this structure. As can be seen from fig. 5, the air outlet covers 5 and 6 are arranged at intervals from front to back. During operation of the refrigerator, heat generated by the compressor and the condenser is radiated from the opening 62c of the exhaust cover 62 through the exhaust hole 61 provided in the exhaust cover 6, the exhaust hole 51 provided in the exhaust cover 5, and the opening 52c of the exhaust cover 52, as indicated by arrow a.

On the other hand, the infiltration of rain and snow falling within the range of the angle between the vertical line Y and the horizontal line X in fig. 5 into the equipment room 3 is prevented by the exhaust cover 52 provided in the exhaust port cover 5. Further, as shown by arrow B, rain and snow flying due to a storm or raindrops rebounded from the installation surface of the vending machine due to a rainstorm may pass through the opening 52c of the exhaust cover 52 of the exhaust port cover 5. However, the infiltration of rain and snow in the direction of arrow B through the opening 52c of the exhaust cover 52 and the exhaust hole 51 into the equipment room 3 is prevented by the exhaust cover 62 provided in the exhaust port cover 6. Therefore, rain and snow passing through the opening 52c of the exhaust cover 52 in the direction of arrow B can be prevented from flying to the deep side inside the equipment room 3. It cannot be denied that water droplets of rain and snow that have touched the exhaust cover 62 provided on the exhaust port cover 6 enter the equipment room 3 from the exhaust hole 61 of the exhaust port cover 6 through the upward opening 62c of the exhaust cover 62, but flow down along the plate surface of the exhaust port cover 6 and are discharged to the outside through the ventilation slit 1h (see fig. 1 b) provided on the base 1e, and therefore the water droplets do not reach the electric equipment of the condensation unit 4 of the refrigerator provided inside the equipment room 3 and the electric components provided inside the equipment room 3.

As described above, in the vending machine according to embodiment 1, the condensation unit 4 of the refrigerator is disposed in the equipment room 3 of the main body cabinet 1, the exhaust port 50 is formed in a portion corresponding to the equipment room 3 on the back surface of the main body cabinet 1, the exhaust port cover 5 having the plurality of exhaust holes 51 in the plate-like plate surface and the exhaust port cover 6 having the plurality of exhaust holes 61 in the plate-like plate surface are provided in the exhaust port 50, wherein at least two sets of the exhaust port covers 5 and 6 are provided, and the two sets of the exhaust port covers 5 and 6 are disposed at a distance from each other in a front-rear state, so that heat generated by the compressor and the condenser is radiated to the outside through the exhaust holes 51 and 61 provided in the exhaust port covers 5 and 6 during operation of the refrigerator, while rain and snow penetrating from the exhaust hole 51 of the exhaust port cover 5 exposed to the outside of the machine are prevented from penetrating the other exhaust port cover 6, therefore, it is possible to reduce infiltration of rain and snow into the equipment room 3.

Next, a vending machine according to embodiment 2 of the present invention will be described with reference to fig. 6 to 8. Fig. 6 is a rear perspective view of the vending machine according to embodiment 2 of the present invention, and fig. 7 is a perspective view of the periphery of the air outlet shown in an exploded manner in the front and rear air outlet covers of the vending machine of fig. 6. Fig. 8 is a rear view of two sets of the exhaust ports covers stacked in front and rear as viewed from the back side. In fig. 6 and 7, the same components as those of the vending machine according to embodiment 1 shown in fig. 1 to 5 are denoted by the same reference numerals, and the description thereof is omitted.

The vending machine according to embodiment 2 shown in fig. 6 to 8 is different from the vending machine according to embodiment 1 shown in fig. 1 to 5 in that air outlet covers 7 and 8 provided at an air outlet 50 and arranged at a distance from each other in the front-rear direction. The outer shape of each of the air outlet covers 7 and 8 is also the same as that of the air outlet covers 5 and 6 of the vending machine according to embodiment 1, and 3

engaging claws

7a, 7a and 7a protruding downward are formed on the lower edge of the air outlet cover 7, screw through

holes

7b and 7b are formed in the upper portions of the left and right sides of the plate surface of the air outlet cover 7, and mounting

pieces

82 and 82 formed by bending outward in the form of a step higher than the plate surface of the air outlet cover 8 are provided on the left and right ends of the air outlet cover 8. Screw through

holes

8b, 8b similar to the screw through

holes

7b, 7b formed in the upper portions of the left and right sides of the plate surface of the exhaust port cover 7 are formed in the

attachment pieces

82, 82.

A plurality of air outlet holes 71 are formed in the plate surface of the air outlet cover 7, and a plurality of air outlet holes 81 are formed in the plate surface of the air outlet cover 8. The air outlet hole 71 formed in the air outlet cover 7 and the air outlet hole 81 formed in the air outlet cover 8 are formed as long holes. The exhaust holes 71 formed in the exhaust port cover 7 are arranged in 17 layers in the vertical direction and in two rows in the horizontal direction, and the exhaust holes 81 formed in the exhaust port cover 8 are arranged in 17 layers in the vertical direction and in 3 rows in the horizontal direction. In a state where the air outlet covers 7 and 8 are assembled to the main body cabinet 1, the air outlet hole 71 provided in the air outlet cover 7 and the air outlet hole 81 provided in the air outlet cover 8 are arranged so as not to overlap each other in the front-rear direction. That is, fig. 8 is a rear view of the exhaust covers 7 and 8 stacked in front and rear as viewed from the back side, and as can be seen from fig. 8, the plurality of exhaust holes 71 provided in the exhaust cover 7 and the plurality of exhaust holes 81 provided in the exhaust cover 8 are shifted in position so as not to overlap each other in the front-rear direction.

Similarly to the air outlet covers 5 and 6 of the vending machine according to embodiment 1, the air outlet covers 7 and 8 having this configuration are also arranged so as to be spaced from each other in the front-rear direction. Heat generated by the compressor and the condenser during operation of the refrigerator is dissipated to the outside through the exhaust hole 81 provided in the exhaust cover 8 and the exhaust hole 71 provided in the exhaust cover 7.

On the other hand, since the exhaust hole 71 of the exhaust cover 7 and the exhaust hole 81 of the exhaust cover 8 of the vending machine according to embodiment 2 are not provided with the exhaust cover 52 provided in the exhaust hole 51 of the exhaust cover 5 and the exhaust cover 62 provided in the exhaust hole 61 of the exhaust cover 6 of the vending machine according to embodiment 1, rain and snow falling from above, rain and snow flying due to storm, and raindrops rebounded from the installation surface of the vending machine due to storm sometimes pass through the exhaust hole 71 of the exhaust cover 7. However, since the air outlet hole 81 provided in the air outlet cover 8 is provided so as to be shifted in position from the air outlet hole 71 of the air outlet cover 7 in the left-right direction, the penetration of rain and snow into the equipment room 3 through the air outlet hole 71 of the air outlet cover 7 is prevented by the air outlet cover 8. Therefore, rain and snow passing through the exhaust hole 71 of the exhaust cover 7 can be prevented from flying to the deep side inside the equipment room 3. Although it cannot be denied that water droplets of rain and snow that have touched the air outlet cover 8 enter the equipment room 3 through the air outlet hole 81, the water droplets flow down along the plate surface of the air outlet cover 8 and are discharged to the outside through the air vent slit 1h provided in the base 1e, and therefore the water droplets do not reach the equipment and electric components of the condensation unit 4 of the refrigerator provided in the equipment room 3.

As described above, the automatic vending machine according to embodiment 2 is configured such that the condensation unit 4 of the refrigerator is disposed in the equipment room 3 of the main body case 1, the air outlet 50 is formed in a portion corresponding to the equipment room 3 on the back surface of the main body case 1, the air outlet cover 7 having the plurality of air outlet holes 71 on the plate-like plate surface and the air outlet cover 8 having the plurality of air outlet holes 81 on the plate-like plate surface are provided in the air outlet 50, at least two sets of the air outlet covers 7 and 8 are provided, and the two sets of the air outlet covers 7 and 8 are disposed at intervals from each other in a front-rear state, whereby heat generated by the compressor and the condenser during operation of the refrigerator is radiated to the outside through the air outlet holes 71 provided in the air outlet 7 and the air outlet holes 81 provided in the air outlet cover 8, and rain and snow penetrating from the air outlet hole 71 of the air outlet cover 7 exposed to the outside of the machine are also radiated to the other air outlet cover The block 8 prevents infiltration, and therefore has an effect of reducing infiltration of rain and snow into the equipment room 3.

In the vending machine according to each of the above embodiments, the back plate 1c is a short plate extending to the upper ends of the reinforcing

1f and 1g on the left and right sides of the base 1e, but the present invention is also applicable to a case where the back plate 1c is a long plate extending to the base 1e and an air outlet is formed in the back plate 1 c. In this case, the material of the exhaust port cover is a cut-out portion (end of cut れ in japanese) obtained by cutting the back plate to form the exhaust port, so that the cut-out portion does not need to be disposed of, and waste of material cost can be avoided. In the case of using the cutout portion as the exhaust port cover, when the exhaust port is punched in the back plate by the press punch, in order to attach the cutout portion (exhaust port cover) to the edge portion of the exhaust port of the back plate, a pair of left and right (or a pair of upper and lower) convex attachment pieces formed on the upper edge and the lower edge (or both the left and right edges) of the cutout portion (exhaust port cover) may be made asymmetric (vertically asymmetric), and the pair of left and right (or a pair of upper and lower) convex attachment pieces may be screwed to the edge portion of the exhaust port of the back plate by turning the cutout portion (exhaust port cover) left and right.

In the vending machine according to each of the above embodiments, the air outlet cover 5 or the air outlet cover 7 is disposed flush with the back plate 1c, but in the case where there is no space in which the two sets of air outlet covers are disposed at a distance from each other inside the equipment room 3, at least one of the two sets of air outlet covers may be disposed outside the machine. In this case, the exhaust port cover disposed on one side of the device may be formed in a box shape having a thin opening on one side, and the exhaust hole may be formed in the bottom surface of the exhaust port cover. Therefore, the present invention is not limited to the vending machine of the embodiment.
