Description

  The present invention relates to a vending machine such as a canned beverage, and more particularly to a vending machine designed to improve the efficiency of heat exchange and reduce power consumption.

[vending machine]
FIGS. 23 and 24A and 24B are a front sectional view, a side sectional view, and an enlarged sectional view showing a configuration of a conventional vending machine, respectively.
23 and 24, a vending machine 900 has a product storage unit 10 surrounded by an inner door 12 that can be opened and closed on one side (front surface) and a heat insulating wall 11 on the other side. Is divided into a plurality of product storage rooms by a partition wall 18. Hereinafter, the case where there are three product storage rooms will be described. In other words, the product storage chamber 13a and the product storage chamber 13b are partitioned by the partition wall 18ab, and the product storage chamber 13b and the product storage chamber 13c are partitioned by the partition wall 18bc.
In the following description, the alphabets a, b, or c of the symbols indicating the respective parts are arranged in the product storage rooms a, b, or c, respectively, and the alphabets are not added to the symbols indicating the parts. Indicates that the position does not matter.

  Each of the product storage chambers 13 stores a product storage unit 14 that stores the product and sequentially transfers the product downward, and a product discharged from the product storage unit 14 through a product transport port 19 (opening through the inner door 12). A product carry-out chute 30 (hereinafter referred to as a chute) that is guided toward the product), a heat exchanger 25 and a heater 28 and a fan 29 that are disposed below the chute 30, An air intake duct 15 for circulating air in the product storage chamber 13 (hereinafter referred to as internal air) toward the heat exchanger 25 via the inside is installed.

[Cooling unit]
The cooling unit 21 is disposed outside the product storage chambers 13a, 13b, and 13c, and an accumulator, a compressor, and a condenser are connected in series by a refrigerant pipe (not shown). The refrigerant pipe branches downstream of the condenser, and the product storage chambers 13a, 13b, 13c (same as the heat exchangers 25a, 25b, 25c) via capillary tubes installed in the branched refrigerant pipes, respectively. In addition, after exiting the product storage chambers 13a, 13b, and 13c, they are again integrated into the refrigerant piping and connected to an accumulator (not shown).

  Therefore, the refrigerant sent out from the compressor flows through the refrigerant pipe, dissipates heat in the condenser, and condenses. Thereafter, the product is distributed to predetermined product storage chambers 13a, 13b, and 13c by opening and closing electromagnetic valves respectively installed in the branched refrigerant pipes. Further, the refrigerant heat-exchanged in the heat exchangers 25a, 25b, and 25c is integrated into the refrigerant pipe, and returns to the compressor through an accumulator for gas-liquid separation (not shown).

[Operation mode]
In the vending machine 900 having the cooling unit 21 configured as described above, the product storage chambers 13a, 13b, and 13c are used as cooling chambers or heating chambers depending on the type and season of the products, and are switched appropriately as needed. Yes. For example, when all the product storage chambers are cooled or heated, a specific product storage chamber may be cooled to heat other product storage chambers.

[Product delivery chute]
FIG. 25 is a perspective view showing a product carry-out chute in a conventional vending machine. The product carry-out chutes 30a, 30b, and 30c are installed in the product storage chambers 13a, 13b, and 13c (see FIG. 23), respectively.
A plurality of through-holes 31 (for example, a diameter of 10 mm, hereinafter referred to as a vent hole) are provided, each of which is formed of about one or two plates and blows out the internal air toward a specific place. . That is, the vent holes 31 are provided in advance in the range where the internal air is desired to flow, and the vent holes 31 are not provided in the range where the internal air is not desired to flow.
The arrangement of the vent holes is determined in a predetermined pattern in consideration of the temperature distribution of the products stored in the product storage room adjacent to the product storage room, assuming various operation modes. It is fixed and cannot be opened or closed later depending on the operating mode and operating conditions of the vending machine.

  The chute 30 is disposed obliquely in the depth direction so as to be lowered from the back of the product storage chamber 13 toward the front, and has a shape for guiding the product to the front (where the product transport port 19 is installed). Yes. And if the angle and position of the chute 30 and the slipperiness of the surface are poor, the product cannot be guided smoothly. Therefore, the angle and position are determined by many actual machine tests, and the product is made smooth. The fact that it can be transported has been confirmed by tens of thousands of sales results in actual vending machines.

[Wind flow]
In the vending machine 900, for example, when the heat exchanger 25a is operated in the commodity storage chamber 13a, the internal air cooled in the heat exchanger 25a is sent by the fan 29a and is not shown in the figure provided in the chute 30a. The air is blown obliquely upward from the air holes and the air gap (which will be described below), collides with the product stored in the product storage unit 14a, cools it, and then the intake duct (not shown) of the intake duct 15a (for example, From the floor surface) is sucked into the intake duct 15a, discharged from an exhaust port (not shown) of the intake duct 15a, and sucked into the heat exchanger 25a. A part of the flow of the internal air is schematically shown by arrows in FIG.

  On the other hand, for example, when the heater 28c is operated in the product storage chamber 13c, the internal air heated in the heater 28c is sent by the fan 29c and is provided in the chute 30c through a ventilation hole 31a or a ventilation gap (not shown). The product is blown obliquely upward, collides with the product stored in the product storage unit 14c and heats it, and is then sucked into the intake duct 15c from the intake port (not shown) of the intake duct 15c and from the exhaust port (not shown) of the intake duct 15c. It is discharged and sucked into the heater 28c (see FIG. 24B).

The wind that has passed through the vent hole 31 of the chute 30 is blown toward the front side (same as the inner door 12 side). In fact, since there is a gap (for example, 5 to 15 mm, referred to as a ventilation gap) between the chute 30 and the heat insulating wall 11 or the partition wall 18, there is a wind passing through the ventilation gap. Yes.
Further, the fan 29 may stop, and in this case, it is considered that convection or circulation is occurring slightly in the natural convection.
Furthermore, although the flow of wind generated above the chute 30 is not properly grasped, the number of products stored in the product storage unit 14 (the remaining is less when sales are favorable) and the shape of the product (It is expected to change depending on the length of long cans and bottles, short short cans and short bottles, or PET bottles with a narrow neck.) However, it was not easy to keep the temperature within the target temperature.

[Product cooling and heating technology]
Therefore, in order to eliminate such problems, a technology that realizes partial cooling and partial heating that arranges an air passage shielding plate in the return duct (same as the intake duct) and makes the temperature below the product storage unit suitable for sale. Is disclosed (for example, see Patent Document 1).
Further, a technology is disclosed in which a duct for generating turbulent flow is provided on the blowout side of the cross flow fan, and the air in the cabinet from the cross flow fan is turbulent and diffused throughout the cabinet (see, for example, Patent Document 2). ).
Furthermore, a technique is disclosed in which a wind guide is provided on the lower surface of a delivery chute (same as a product carry-out chute) so that the wind blowing direction is directly above (see, for example, Patent Document 3).
JP 2000-182133 A (page 2-3, FIG. 1) JP 2000-353276 A (page 2-3, FIG. 1) JP 2002-8117 A (page 4, FIG. 4)

However, the invention disclosed in Patent Document 1 has a problem that it cannot cope with a change in the shape of the product or the operation mode.
Further, since the invention disclosed in Patent Document 2 is based on the premise that a cross flow fan is installed, the flow of wind is reversed from that of the vending machine 900, and therefore cannot be employed in the vending machine 900. The problem was left.
Furthermore, the invention disclosed in Patent Document 3 has a problem that it cannot cope with changes in the amount of goods stored, the shape of goods, and the operation mode.

[Embodiment 1]
1 and 2 are a cross-sectional view of a vending machine according to Embodiment 1 of the present invention in a side view and a perspective view showing a product carry-out chute installed in the vending machine. The same parts as those in FIG. 24 are denoted by the same reference numerals, and a part of the description is omitted.

[Product delivery chute]
In FIG. 1 and FIG. 2, a product carry-out chute 40 (hereinafter referred to as a chute) is formed by an upper plate 50 and a lower plate 60.
The upper plate 50 is provided with a plurality of through holes 51 (hereinafter referred to as vent holes), and the lower plate 60 is provided with a plurality of through holes 61 (hereinafter referred to as vent holes). The form (hole shape, size, arrangement (distribution), etc.) of the vent hole 51 and the vent hole 61 is appropriately selected (this will be described separately).

  Further, the upper plate 50 and the lower plate 60 are relatively moved in parallel (translation or rotation), moved so as to be close to or away from each other, or an angle formed by each other is changed (one is tilted). is there. Due to the movement or the like, the vent hole 51 and the vent hole 61 interfere with each other, and the shape and quantity of the opening formed by the vent hole 51 and the vent hole 61 (hereinafter referred to as the vent opening part) are changed. (This will be described separately).

  Further, the means for performing the movement or the like is not limited, and may be a power operation type using a motor, an actuator or the like, or a manual operation type by human power. Furthermore, in the case of the power operation type, it is possible to use a stand-alone automatic control linked to a predetermined control system for each vending machine or a remote control type automatic control connected to a network that centrally manages a plurality of vending machines. May be.

  The upper plate 50 has a function necessary for carrying out the product, that is, needs to be disposed so as to secure a passage for smoothly carrying out the product, have a predetermined strength on a slippery surface, and satisfy a slippery angle. Therefore, the upper plate 50 is fixed and the lower plate 60 is movable. However, the present invention is not limited to this, and the lower plate 60 may be fixed by making the upper plate 50 movable.

  The upper plate 50 and the lower plate 60 are slidable in contact with each other, or are arranged through a predetermined gap, or a gap sealing means is inserted in the gap. Also good. Furthermore, a third plate member (such as an intermediate plate) provided with a vent hole may be further disposed on one or both of the upper and lower sides of the lower plate 60.

[Interference between ventilation holes]
3 to 5 are schematic views (plan view) for explaining interference between the air holes in the vending machine shown in FIG. 1, and show a part of the upper plate and the lower plate. In the following description, a through-hole formed in the chute in advance is referred to as a ventilation hole, and an opening formed by the interference between the ventilation hole of the upper plate and the ventilation hole of the lower plate is referred to as a ventilation opening.

[Interference between ventilation holes-1]
In FIG. 3, for ease of explanation, the vent hole 51 of the upper plate 50 of the chute 41 and the vent hole 61 of the lower plate 60 are both in the shape of a circle having a diameter of 15 mm. The shape is not limited to the above, and may be any of a diameter, a plan view shape (such as a circle, an ellipse, or a rectangle (slit shape)) or a side view shape (such as a cylindrical shape, a tapered shape, or a trumpet shape). Further, the vent hole 51 and the vent hole 61 may be different from each other in size, plan view shape, or side view shape. Moreover, although the translation (in the figure, the left-right direction or the up-down direction) is exemplified as the relative movement, it may be rotated about a predetermined position.

  In FIG. 3A, one vent hole 51 (hereinafter referred to as a vent hole 52) of the upper plate 50 is spaced from the other vent hole 51 (hereinafter referred to as a vent hole 53). (Center-to-center distance) is provided with a space of 40 mm, and one vent hole 61 (hereinafter referred to as a vent hole 62) of the lower plate 60 and the other vent hole 61 (hereinafter referred to as a vent hole 63) are referred to for convenience. ) With a space of 40 mm. And since the vent hole 52 and the vent hole 62 and the vent hole 53 and the vent hole 63 overlap each other, the chute 41 has two circular vent openings with a diameter of 15 mm in the range shown in the figure. ing.

  In FIG. 3B, the upper plate 50 or the lower plate 60 is relatively moved 10 mm in the horizontal direction in the drawing. For this reason, a vertically long ventilation opening is formed by the right arc of the ventilation hole 52 and the left arc of the ventilation hole 62, and similarly, a vertically long ventilation opening is formed by the ventilation hole 53 and the ventilation hole 63. In other words, the relative movement reduces the area of the ventilation opening in plan view, so that the amount of air blown out from the chute 41 in the range shown in the figure is reduced, or the flow velocity of the blown air is increased.

  In FIG. 3C, the upper plate 50 or the lower plate 60 is further moved 10 mm relatively in the lateral direction in the drawing. At this time, since the ventilation hole 62 is located between the ventilation hole 52 and the ventilation hole 53 and none of the ventilation holes interfere (overlap), the chute 41 does not have a ventilation opening in the range shown in the figure. become.

[Interference between ventilation holes-2]
In FIG. 4, the chute 42 has a space between air holes 51 (referred to as air holes 52, 53 for convenience) provided in the upper plate 50 and air holes 71 (air holes 72, 73 provided for convenience) provided in the lower plate 70. Is different from the interval. That is, the interval between the vent holes 52 and 53 in the plate 50 is 40 mm (same as in FIG. 3), whereas the interval between the vent holes 72 and 73 in the lower plate 70 is 22.5 mm.

  In FIG. 4A, the vent hole 52 of the upper plate 50 and the vent hole 72 of the lower plate 70 overlap, and the vent hole 53 and the vent hole 73 do not interfere (do not overlap). Is formed with one circular ventilation opening having a diameter of 15 mm in the range shown in the figure.

  In FIG. 4B, the upper plate 50 or the lower plate 70 is relatively moved 10 mm in the horizontal direction in the drawing. For this reason, a vertically long vent opening is formed by the right arc of the vent hole 52 and the left arc of the vent hole 72, and further, a vertically long vent opening is formed by the left arc of the vent hole 53 and the right arc of the vent hole 73. It is formed. That is, as a result of the relative movement, the number of ventilation openings in the chute 42 is increased from one to two in the range shown in the figure.

In FIG. 4C, the upper plate 50 or the lower plate 70 is further moved by 7.5 mm in the horizontal direction in the drawing. At this time, the vent hole 52 and the vent hole 72 do not interfere with each other, and the vent hole 53 and the vent hole 73 overlap each other. Therefore, the chute 41 has one vent opening in the range shown in the drawing.
That is, the relative movement (from (a) to (c)) means that the air blowing position of the chute 42 has moved by a predetermined distance after the ventilation opening has increased to two locations during the movement. When the interval between the vent holes 52 and 53 of the upper plate 50 is large, the vent holes 52 and 53 of the upper plate 50 do not interfere with any of the vent holes 62 and 63 of the lower plate 60 during the relative movement. Therefore, after the ventilation opening is temporarily removed during the movement, the air blowing position of the chute 42 moves by a predetermined distance.

[Interference between ventilation holes-3]
In FIG. 5, the chute 43 is a chute 42 shown in FIG. 4 in which an intermediate plate 80 is disposed between the upper plate 50 and the lower plate 70 or below the lower plate 70. The intermediate plate 80 is provided with a slit-like through groove 82 (hereinafter referred to as a ventilation groove). The same parts as those in FIG. 4 are denoted by the same reference numerals, and a part of the description is omitted.

  5A, the vent hole 52 of the upper plate 50, the vent hole 72 of the lower plate 70, and the vent groove 82 of the middle plate 80 are overlapped to form a substantially semicircular vent opening. On the other hand, the vent hole 53 of the upper plate 50 does not interfere with the vent hole 73 of the lower plate 70 and the vent groove 82 of the middle plate 80, and the vent hole 73 of the lower plate 70 is the vent hole 53 of the upper plate 50 and the middle plate 80. Since there is no interference with the ventilation groove 82, each is closed. That is, the size of the vent opening changes depending on the degree of overlap of the middle plate 80 with the vent groove 82.

In FIG. 5B, the upper plate 50 or the lower plate 70 is relatively moved 10 mm in the horizontal direction in the figure, and the middle plate 80 is moved downward. For this reason, a vertically long vent opening is formed by the right arc of the vent hole 52 and the left arc of the vent hole 72, and further, a vertically long vent opening is formed by the left arc of the vent hole 53 and the right arc of the vent hole 73. Further, the entire area of the vertically long ventilation opening portion overlaps with the ventilation groove 82 of the intermediate plate 80.
That is, if the upper plate 50 or the lower plate 70 is moved relatively in the horizontal direction without moving the middle plate 80, the ventilation openings are increased to two places, and the plane shape is substantially triangular. Therefore, a vertically long ventilation opening is formed. That is, if the middle plate 80 is relatively moved in the vertical direction by a predetermined distance or is not moved, the shape and area of each vent opening can be changed. At this time, the intermediate plate 80 may be rotated.

In FIG. 5C, the upper plate 50 or the lower plate 70 is further moved by a further 7.5 mm in the lateral direction in the drawing, and the middle plate 80 is further moved downward. At this time, the vent hole 53 of the upper plate 50, the vent hole 73 of the lower plate 70, and the vent groove 82 of the middle plate 80 are overlapped to form a substantially semicircular vent opening.
That is, if the upper plate 50 or the lower plate 70 is moved relative to the horizontal direction without moving the middle plate 80, the plane shape of the ventilation opening becomes circular (see FIG. 4C). Is moved downward, a substantially semicircular vent opening is formed.
Therefore, in the relative movement ((a) to (c)), by moving the middle plate 80, the area of the ventilation opening that occurs during the relative movement of the upper plate 50 or the lower plate 70 can be kept substantially constant. Therefore, the air blowing position can be moved without changing the amount of blown air.

[Vent hole layout]
6 to 10 are perspective views for explaining an embodiment of the arrangement of the vent holes and vent openings in the chute of the vending machine shown in FIG. In the following description, the same reference numerals are given to the last two digits of the same reference numerals as in FIG. 1, and a part of the description will be omitted. Further, although a vending machine having three product storage rooms will be described, the present invention can also be applied to a vending machine having four or more rooms. Further, the arrangement form of the air holes (number of rows and columns) is not limited to that shown in the figure, and any quantity may be used, and the arrangement may be any of square, staggered, or a predetermined pattern. There may be.
Further, the upper plate and the lower plate are convenient names, and the upper plate may be disposed below the lower plate. Further, in relative movement, either the upper plate or the lower plate may be moved, or both may be moved.

[Venting hole arrangement example-Combination example 1]
In FIG. 6A, the upper plate 150 of the chute 140 is provided with a vent hole 151 arranged in a grid pattern, and the lower plate 160 has a through hole arranged in a grid pattern at the same pitch as the vent holes 151. A pore 161 is provided.

  In FIG. 6 (b), all the vent holes 151 of the upper plate 150 and all the vent holes 161 of the lower plate 160 are overlapped to form a vent opening that is arranged in a grid shape (FIG. 3 (a)). reference). Therefore, the chute 140 behaves as if only one of the upper plate 150 and the lower plate 160 is disposed.

  In FIG. 6C, as a result of the relative movement of the upper plate 150 and the lower plate 160 by a predetermined distance, all the vent holes 151 and the vent holes 161 are not overlapped, and the chute 140 has no vent openings. (See (c) of FIG. 3). Accordingly, the chute 140 behaves as if it is formed of a solid (no vent) plate material.

In the middle of the process from (b) to (c) in FIG. 6, the shape of the vent opening changes when the vent hole 151 and the vent hole 161 partially overlap each other, so the relative movement amount is adjusted. Thus, it is possible to adjust the air flow rate and the air flow rate (see FIG. 3B).
Therefore, the chute 140 can meet the request for appropriately changing the size of the ventilation opening, and particularly the request for completely closing the ventilation opening.

For example, when the product storage chamber 13 is used as a cooling chamber, the compressor 21 is operated until a predetermined lower limit temperature is reached in order to maintain the temperature of the product stored in the product storage unit 14 within the target temperature. In order to cool the internal air in the heat exchanger 25 (heat exchange), the operation of the fan 29 is continued to circulate the internal air (hereinafter referred to as an ON state).
On the other hand, after reaching the predetermined lower limit temperature, until the predetermined upper limit temperature is reached, the operation of the fan 29 or the like is stopped to prevent the circulation of the internal air (hereinafter referred to as the off state).

  Therefore, when the chute 140 is in the ON state, it is possible to cope with the necessity of arranging the ventilation opening at a necessary place. In the off state, the ventilation opening can be closed to suppress the natural convection of the internal air, and the gap that becomes the passage of the internal air can be closed as much as possible, and the effect of minimizing heat loss is expected. The Further, when the fan 29 or the like is operated at a low load when the predetermined temperature state is maintained, the size of the ventilation opening is sufficient and necessary for maintaining the convection of the air in the cabinet corresponding thereto. Can be adjusted.

[Venting hole arrangement example-Combination example 2]
In FIG. 7A, the upper plate 250 of the chute 240 is provided with air holes 251 arranged in a square shape on the entire surface, and the lower plate 260 is arranged in a square shape at the same pitch as the air holes 251. A vent hole 261 is provided on the entire surface, and is further in parallel with the vent hole 261 between the first and second rows on the left side and between the second and third rows on the left side in the figure. A vent hole 262 is provided.

  In FIG. 7B, a ventilation opening is formed in which the ventilation hole 251 of the upper plate 250 and the ventilation hole 261 of the lower plate 260 overlap each other and are arranged in a grid pattern (see FIG. 4A). . Therefore, the chute 240 behaves as if only the upper plate 250 is disposed.

  In FIG. 7C, as a result of the relative movement of the upper plate 250 and the lower plate 260 by a predetermined distance, the vent hole 251 and the vent hole 261 are not overlapped. However, the vent hole 251 and the vent hole 262 overlap with each other, and two rows of vent openings are formed on the left side (see FIG. 4C). That is, the chute 240 can blow the internal air uniformly over the entire surface in (b), and in (c), the internal air can also be blown out limited to a limited range on the left side.

  For example, in a vending machine having three product storage rooms (hereinafter referred to as a left warehouse, a middle warehouse, and a right warehouse), the left warehouse is kept warm and the inside and right warehouse are cooled. In the holding state, the air temperature in the refrigerator during cooling is −10 to + 20 ° C. (the next sale product temperature is aimed at 4 ° C., the management range is 1 to 7 ° C.), and the air temperature in the refrigerator during heating is 30 to 70 ° C. (The next sale product temperature is aimed at 55 ° C, management range 53-58 ° C), and the outside air temperature is guaranteed to be -5 ° C to + 38 ° C (may be -5 ° C or less depending on the temperature conditions in various parts of Japan) Yes.

  At this time, there is almost no heat transfer between the warehouse because the temperature in the middle warehouse and the right warehouse is almost the same, but there is not a little heat transfer between the left warehouse and the middle warehouse. . That is, since the left side of the inner warehouse is difficult to be cooled due to the movement of heat from the left warehouse, if a chute 240 is installed in the middle warehouse, a large amount of air in the warehouse is blown out in the range closer to the left warehouse. Thus, it becomes possible to reduce the temperature difference between the products stored in the lowermost part of each product storage unit (hereinafter referred to as the distribution of the product temperature in the warehouse) (see (c) of FIG. 7).

  Furthermore, when all the rooms are switched to the cooling and holding state, it is possible to blow out the air in the cabinet from the entire surface of the chute 240 in the middle warehouse, thereby reducing the distribution of the product temperature in the warehouse ((b) in FIG. 7). reference).

Note that the present invention is not limited to the above operation mode, and even when all the product storage rooms are in the cooling holding state, the side wall side of the product storage room located at the side end of the vending machine (for example, A relatively large amount of air in the warehouse may be blown out in the left range of the left warehouse and the right area of the right warehouse to reduce the distribution of the product temperature in the warehouse.
Further, in the drawing of the lower plate 260, the vent holes 262 are arranged on the back side (same as the rear side) or the front side (same as the front side), and the upper plate 250 or the lower plate 260 is arranged in the depth direction (same in the front-rear direction). The amount of air blown in the cabinet may be adjusted in the depth direction of the product storage chamber (the same in the front-rear direction).

[Venting hole arrangement example-Combination example 3]
In FIG. 8A, vent holes 351 arranged in a grid pattern at a predetermined pitch are arranged in the right half of the upper plate 350 of the chute 340, and grid holes are arranged in a grid pattern at the same pitch as the vent holes 351 in the left half. The space 353 between the leftmost row of the right vent holes 351 and the rightmost row of the left vent holes 352 is different from the pitch. On the other hand, the lower plate 360 is provided with vent holes 361 arranged in a square pattern at the same pitch as the vent holes 351 on the entire surface.

  In FIG. 8B, the ventilation hole 351 on the right side of the upper plate 350 and the ventilation hole 361 of the lower plate 360 overlap to form a ventilation opening arranged in a square shape on the right half of the upper plate 350. (See (a) of FIG. 5). Therefore, the chute 340 behaves as if the air holes are arranged only in the right half thereof.

  In FIG. 8C, as a result of the relative movement of the upper plate 350 and the lower plate 360 by a predetermined distance, the ventilation hole 352 on the left side of the upper plate 350 and the ventilation hole 361 of the lower plate 360 overlap each other. A ventilation opening arranged in a grid shape is formed in the left half of the plate 350 (see FIG. 5C).

  Further, in the middle from FIG. 8B to FIG. 8C, the overlapping form of the vent hole 351 and the vent hole 361 and the overlapping form of the vent hole 352 and the vent hole 361 change, so that the relative movement amount is changed. By adjusting, the ventilation opening can be formed on the entire surface or half of the chute 340, and further, the amount of ventilation and the ventilation speed in the ventilation opening can be adjusted (see FIG. 4B). .

Therefore, the chute 340 is suitable when it is desired to blow the internal air only to one side of the right half or the left half, or when it is desired to blow a predetermined amount of the internal air over the entire surface of the chute 340.
For example, in a vending machine having three product storage rooms (left warehouse, middle warehouse, right warehouse), if a chute 340 is installed in the middle warehouse, the heat leak from the left warehouse or right warehouse is offset. Since the inside air can be blown out to the desired side, if the chute 340 is installed in the left or right warehouse, the desired side can be offset so as to offset the heat leak from the inside or outside air. Since the inside air can be blown out, the distribution of the inside product temperature is reduced.

  A vent hole 351 is provided in the back half of the upper plate 350, a vent hole 352 is provided in the front half, and the upper plate 350 and the lower plate 360 are relatively moved in the depth direction (same in the front-rear direction). The amount of air blown in the cabinet may be adjusted in the depth direction of the product storage room.

[Venting hole arrangement example-Combination example 4]
In FIG. 9A, vent holes 451 are provided in a grid pattern at a predetermined pitch on the entire surface of the upper plate 450 of the chute 440, and each of the five rows in the back (upward in the figure) of the vent holes 451 is provided. A vent hole 453 is provided in the middle of the column, and a vent hole 452 is provided in the middle of each column in a range of five rows before the vent hole 451 (downward in the drawing). On the other hand, the lower plate 460 is provided with ventilation holes 461 arranged in a square pattern at the same pitch as the ventilation holes 451.

  In FIG. 9B, since the vent hole 451 of the upper plate 450 and the vent hole 461 of the lower plate 460 overlap each other, the chute 440 behaves as if it is constituted only by the lower plate 460.

In FIG. 9C, as a result of the relative movement of the upper plate 450 and the lower plate 460 by a predetermined distance, the vent hole 453 at the back of the upper plate 450 and the vent hole 461 of the lower plate 460 overlap each other. Since the vent hole 452 in front of the upper plate 450 and the vent hole 461 in the lower plate 460 overlap with each other, the chute 440 has a predetermined range in the back (range of 5 rows) and a predetermined range in front (range of 5 rows). A ventilation opening is formed.
Further, in the middle from (b) to (c) of FIG. 9, since the overlapping form of the vent holes 451 and 461 and the overlapping form of the vent holes 453 and 452 and the vent hole 461 change, relative movement is performed. By adjusting the amount, the amount of air flow and the speed of air flow can be adjusted over the entire surface or part of the chute 440.

Therefore, the chute 440 is suitable when it is desired to blow the internal air only in the predetermined range in the back and the predetermined range in front, or when it is desired to blow a predetermined amount of the internal air over the entire surface of the chute 440.
In accordance with the above, vent holes 453 and 452 are provided in a predetermined range in the back and a predetermined range in front, and the upper plate 450 and the lower plate 460 are relatively moved in the depth direction (the same in the front-rear direction), so The inside air may be blown out only within a predetermined range.

On the other hand, the 4 rows × 3 columns vent holes 554 that are displaced in both the right direction and the forward direction are offset in the right direction and the forward direction with respect to the 3 rows × 3 columns vent holes 551 on the right side. Each of the three rows and three columns of vent holes 555 are provided.
On the other hand, the lower plate 560 is provided with vent holes 561 arranged in a grid pattern at the same pitch as the vent holes 551 on the entire surface.

  In FIG. 10B, since the vent hole 551 of the upper plate 550 and the vent hole 561 of the lower plate 560 overlap each other, the chute 540 seems to be constituted only by the lower plate 560 having the vent holes on the entire surface. It is behaving.

  In FIG. 10C, as a result of the relative movement of the upper plate 550 and the lower plate 560 in the left-right direction (the same in the row direction) by a predetermined distance, the ventilation hole 552 provided on the far left side of the upper plate 550 is now obtained. And the vent hole 561 of the lower plate 560 are overlapped, and there is no interference with the other vent holes 551, 553, 554, 555, so that the chute 540 has a vent opening of 4 rows × 3 columns in a predetermined range on the far left side. It will be done.

  In FIG. 10D, as a result of the relative movement of the upper plate 550 and the lower plate 560 in the forward direction (same in the row direction) by a predetermined distance, the air holes 553 provided in front of the upper plate 550 are now obtained. And the vent holes 561 of the lower plate 560 are overlapped, and there is no interference with the other vent holes 551, 552, 554, 555, so that the chute 540 has 3 rows × 6 columns of vent holes in a predetermined range in front. It will be.

  In FIG. 10E, as a result of the relative movement of the upper plate 550 and the lower plate 560 in both the left and right directions and the forward direction by a predetermined distance, a ventilation hole 554 provided on the far right side of the upper plate 550 is now obtained. And the vent hole 561 of the lower plate 560, and the vent hole 555 and the vent hole 561 provided on the right side on the front side overlap with each other, and there is no interference with the other vent holes 551, 552, 553, so the chute 540 The ventilation openings of 4 rows × 3 columns and 3 rows × 3 columns are formed in a predetermined range on the right side and the front side, respectively. Therefore, it becomes possible to blow out the internal air locally corresponding to the range to be cooled or heated.

Ventilation openings arranged in a square grid are formed.

  Therefore, it is possible to blow out the internal air in a total of four patterns by configuring the lower plate of the combination example 1 (see FIG. 6) to be independently movable in the left-right direction. In addition, the quantity and shape of the vent openings can be further changed at the intermediate movement positions that shift to the respective patterns. Therefore, since the procedure for blowing the internal air can be finely adjusted, it is possible to further promote the guarantee of the product temperature and the prevention of heat loss.

[Arrangement Example of Vents-Combination Example 5-2]
FIG. 15 shows vent openings formed in the case of combination example 5 (FIG. 10) when two lower plates are configured and moved independently from each other. Since the formation procedure is the same as described above (FIGS. 11 to 14), the description is omitted.
In addition, in 2 of combination example 1 to 2 of combination example 5, the lower plate is described as being constituted by two plate materials, but the present invention is not limited to this, and the configuration of three or more pieces It may be. Further, since the plate material may have any shape such as a rectangle, a sector, or a circle, and may have any size, for example, they may be moved relative to each other in a plan view.

[Venting hole arrangement example-Combination example 6]
In FIG. 16A, vent holes 651 are provided in a square pattern at a predetermined pitch on the entire surface of the upper plate 650 of the chute 640. On the other hand, two lower plates, a front lower plate 660 and a rear lower plate 670, are disposed so as to be rotatable about a rotation shaft 662 and a rotation shaft 672, respectively. The front lower plate 660 and the rear lower plate 670 are provided with vent holes 661 and vent holes 671 respectively in a predetermined arrangement form.
The upper plate 650 and the lower front plate 660 are parallel to the upper plate 650 and the lower lower plate 670, and the rotation shaft 662 and the rotation shaft 672 are arranged perpendicular to the upper plate 650, respectively. Although described, the present invention is not limited to this, and the rotating shaft 662 or the rotating shaft 672 may be inclined with respect to the upper plate 650. Further, the front lower plate 660 may be installed inclined with respect to the rotation shaft 662, or the lower lower plate 670 may be installed inclined with respect to the rotation shaft 672. At this time, the effects of the third embodiment to be described later are produced synergistically.

  In FIG. 16B, the vent hole 651 of the upper plate 650 and the vent hole 661 of the front lower plate 660 mainly overlap in the lower right range in the figure, and the vent hole 651 of the upper plate 650 and the lower plate 670 The ventilation hole 671 overlaps mainly in the upper left range in the figure. Further, the surrounding vent holes 651 outside the disk range of the front lower plate 660 of the upper plate 650 and the surrounding vent holes 651 outside the disc range of the lower plate 670 of the upper plate 650 may be blocked. Absent. Therefore, the ventilation hole forms a ventilation opening in the overlapped range, and the air inside the box is blown out from the ventilation opening.

  In FIG. 16C, the front lower plate 660 is rotated by 180 ° with respect to FIG. For this reason, the vent hole 651 of the upper plate 650 and the vent hole 661 of the front lower plate 660 overlap mainly in the upper left range in the figure. In addition, the peripheral vent hole 651 outside the disk range of the lower plate 660 in front of the upper plate 650 and the peripheral vent hole 651 outside the disc range of the lower plate 670 of the upper plate 650 cause the rotation. The inside air is blown out without being affected.

  In FIG. 16D, the lower plate 670 is rotated by 180 ° with respect to FIG. For this reason, the ventilation hole 651 of the upper board 650 and the ventilation hole 671 of the back lower board 670 have overlapped mainly in the lower right range in the figure.

In FIG. 16 (e), the front lower plate 660 and the rear lower plate 670 are each rotated 180 ° with respect to (b). Therefore, the vent hole 651 of the upper plate 650 and the vent hole 661 of the front lower plate 660 overlap mainly in the upper left range in the figure, and the vent hole 651 of the upper plate 650 and the vent hole 671 of the lower lower plate 670 are the main. It overlaps in the lower right range in the figure.
In addition, although the case where both the front lower plate 660 and the back lower plate 670 are formed in a disk shape is illustrated, the present invention is not limited to this, and any shape and size may be used. In addition, the rotation angle is not limited, and the rotation angle may be rotated in two directions (forward rotation and reverse rotation).

[Venting hole arrangement example-Combination example 7]
In FIG. 17A, the upper plate 750 of the chute 740 is provided with air holes 751 arranged in a square shape on the entire surface, and the lower plate 760 is arranged in a square shape at the same pitch as the air holes 751. Ventilation holes 761 are provided on the entire surface (the same as the combination example 1 (see FIG. 6)).

In FIG. 17B, since the relative movement amount between the upper plate 750 and the lower plate 760 is small, a part of the vent hole 751 of the upper plate 750 and a part of the vent hole 761 of the lower plate 760 are overlapped. The internal air is blown out from a vertically long ventilation opening formed by two arcs. Therefore, the amount of ventilation and the rate of ventilation can be adjusted by adjusting the relative movement amount (see FIG. 3B).
In addition, in the combination examples 2 to 6 and the combination example 2 to the combination example 2 to 2, the combination example 7 can be implemented together.

As described above, in the combination example 1 to the combination example 7 and the combination example 2 to the combination example 2 to 2, the internal air can be locally blown out corresponding to the range to be cooled or heated.
For example, generally merchandise is stored in a substantially vertical direction in the merchandise storage unit 14, sold sequentially from the lowest merchandise, and merchandise that has been dispensed (dropped) from the merchandise storage unit 14 uses gravity. With momentum, the product passes through the product transport port 19 and is transported to the sales port at the back of the vending machine.
Then, the next product to be sold (hereinafter referred to as “next sale product”) is at the lowest stage of the product storage unit 14, and the internal air blown out from the vent hole 41 of the chute 40 directly collides, Heat exchange is performed to adjust the temperature appropriately. In addition, the product (second product) stored on the next sale product (the first product) is also subjected to the direct collision of the air inside the warehouse that has passed through the side of the next sale product or the direct collision. Heat is exchanged and adjusted to an appropriate temperature by a secondary collision of the air inside.

However, when a plurality of products are sold continuously, there is a risk that the third and subsequent products may be sold without being adjusted to an appropriate temperature, and therefore, toward the product storage unit 14 in which the products are stored. Since it is necessary to blow out the air in the cabinet locally, the present invention can cope with such a case.
On the other hand, the product storage unit 14 that stores products that have been suspended for a while does not need to be actively blown with air in the cabinet, and is generated by closing or narrowing the ventilation opening in the range. Since it is necessary to reduce the amount of heat, the operating rate, and the power consumption, the present invention can cope with such a case.

In addition, there are many commodity storage units 14 of the vending machine with 4 to 7 in the front direction and 4 to 7 columns in the left and right direction. For example, 5 × 6 = 30 types of products are stored. Some are more diverse. In the vending machine having three product storage rooms, each product is stored in each product storage room according to the operation mode. For example, 12 types of products are stored in the left chamber, 6 types of products are stored in the middle chamber, and 12 types of products are stored in the right chamber, or 15 types of products are stored in the left chamber, and 5 types are stored in the middle chamber. 10 types of products are stored in the right room.
For this reason, since it is desirable to change suitably the blowing method of the air in each store | warehouse | chamber according to the kind of goods which each accommodates, and the sales condition, this invention enables it to respond | correspond to this.

FIG. 18 is a schematic diagram for explaining the interference between the air holes provided in the chute of the vending machine according to the third embodiment of the present invention, and the relative magnitude of the air volume and the air speed between the adjacent air holes. Are qualitatively indicated by the size of the tip of the arrow and the length of the arrow, respectively.
In FIG. 18, the chute 40 is formed by an upper plate 50 and a lower plate 60, and is installed such that a gap can be changed between them. The upper plate 50 and the lower plate 60 are provided with vent holes 51 and 61 arranged at the same pitch, respectively, and the left vent hole 52 and 62, which is arranged at the leftmost in the figure, is used for convenience of explanation. The rightmost one is referred to as right vent holes 53 and 63. In addition, the same code | symbol is attached | subjected to this same part as FIG. 1, and one part description is abbreviate | omitted.

  In FIG. 18A, the upper plate 50 and the lower plate 60 are substantially in close contact with each other, and the vent hole 51 and the vent hole 61 are overlapped with each other in the same phase. As formed by the plate material, the internal air is blown out from the vent hole 51 (same as the vent hole 61).

  In FIG. 18B, the upper plate 50 and the lower plate 60 are arranged apart from each other with a predetermined gap (for example, 0 to 10 mm). For this reason, the decompression layer is formed by the gap, and the amount of the air in the cabinet blown out from the vent hole 51 (same as the vent hole 61) is reduced.

  In FIG. 18C, one of the upper plate 50 and the lower plate 60 tilts, and the distance between the two differs depending on the position. That is, the positions of the right vent holes 53 and 63 are substantially in contact with each other, whereas the positions of the left vent holes 52 and 62 are separated by a predetermined gap. For this reason, in the right vent holes 53 and 63, the internal air is blown out as if it were formed by a single plate material, whereas the gap between the vent hole 51 and the vent hole 61 is increased toward the left side. Therefore, a pressure-reducing layer that gradually increases in thickness is formed, and the amount of internal air blown out from the vent hole 51 (same as the vent hole 61) decreases toward the left side.

In FIG. 18D, the upper plate 50 and the lower plate 60 are relatively moved in both the left-right direction and the up-down direction. For this reason, it blows out from the vent hole 51 (same as the vent hole 61) by the synergistic effect of the reduction | decrease of the ventilation area by the overlap of the vent hole 51 and the vent hole 61 in the left-right direction, and formation of the decompression layer by the clearance gap between the up-down direction. The amount of air in the cabinet has further decreased.
The shape, size, arrangement procedure, and movement procedure of the air holes 51 and 61 are the same as those in the first or second embodiment.

  In FIG. 18E, one of the upper plate 50 and the lower plate 60 is tilted and relatively moved in the left-right direction. Therefore, due to the synergistic effect of the above (c) and (d), the amount of air blown out in the cabinet decreases as the position of the right vent holes 53, 63 shifts to the position of the left vent holes 52, 62. Such a configuration is also formed when the upper plate 50 and the lower plate 60 are arranged to be inclined and relatively rotated.

[Embodiment 4]
FIG. 19 is a schematic diagram for explaining the interference between the air holes provided in the chute of the vending machine according to the fourth embodiment of the present invention, where (a) is a partial side cross-section of the chute and (b) is a chute. FIG. In the following description, the same parts as in FIG.

  19A and 19B, the upper plate 850 and the lower plate 860 of the chute 840 are provided with circular vent holes 851 and 861 at the same pitch, respectively. Further, the lower plate 860 is extendable and shows a state in which the left end portion is fixed and extended rightward. That is, the vent hole 861 of the lower plate 860 is deformed into an oval shape, and the interval between them is extended. Accordingly, the overlapping range of the vent hole 851 and the vent hole 861 gradually decreases from the fixed end (left) to the extended end (right).

Therefore, in the chute 840, when the lower plate 860 is not extended, the internal air can be uniformly blown from the circular ventilation opening to the entire surface of the chute 940. Further, when the lower plate 860 is extended, the air in the cabinet is blown out from the deformed deformed vent opening so as to gradually increase (same as approximately gradually decrease) from one direction to multiple directions over the entire surface of the chute 840. Is possible.
Since the vent holes 851 and 861 are two-dimensionally arranged in the upper plate 850 and the lower plate 860, the extension direction of the lower plate 860 may be two directions. Moreover, you may extend | stretch from both, without providing a fixed end. Furthermore, a compressive force may be applied instead of extension.

Further, the material for forming the lower plate 860 is not limited, and any material can be used as long as it is an easily stretchable material (such as rubber or resin material). Moreover, the arrangement | positioning form of the vent of the upper board 850 and the lower board 860 is based on the said Embodiment 1-3.
Furthermore, the lower plate 860 is not limited to a flat plate, and may be a bellows plate (including a corrugated plate). At this time, since the bellows plate can be easily expanded and contracted in an accordion shape (accordion shape), the position of the vent hole formed in the bellows plate and the projected area on the upper plate fluctuate due to expansion and contraction. Can be changed.

FIG. 20 is a schematic diagram for schematically explaining a ventilation opening provided in a chute of a vending machine according to Embodiment 5 of the present invention, in which (a) and (b) are side cross sections, and (c). Is a plan view. In the following description, the same parts as those in FIG. 1 are denoted by the same reference numerals, and a part of the description is omitted.

  In FIG. 20A, a compressible cushion material 90 is disposed between the upper plate 50 and the lower plate 60. The cushion material 90 is lightly held by the upper plate 50 and the lower plate 60, and the vent hole 51 provided in the upper plate 50, the vent hole 91 provided in the cushion material 90, and the lower plate 60 are provided. All of the air holes 61 overlap at the same position. Therefore, the chute 40 behaves as if it is formed of a single thick plate (having vent holes). That is, the internal air does not leak between the upper plate 50 and the lower plate 60 in the adjacent vent hole direction or the side edge of the chute 40.

  20 (b) and 20 (c), the distance between the upper plate 50 and the lower plate 60 is reduced, and the cushion material 90 is compressed. Therefore, the vent hole 91 provided in the cushion material 90 is deformed. The vent holes 51 and 61 are smaller. That is, as the distance is shortened, the cushion material 90 can be visually recognized from above through the vent hole 51 (see (c)), and the area of the vent opening is narrowed.

Therefore, by adjusting the distance between the upper plate 50 and the lower plate 60, it is possible to adjust the amount of blown-out air in the cabinet. The procedure for changing the relative distance between the upper plate 50 and the lower plate 60 is the same as in the fourth embodiment (FIG. 18).
Further, if both surfaces of the cushion material 90 are bonded to the upper plate 50 and the lower plate 60, respectively, and the upper plate 50 and the lower plate 60 are moved relative to each other in the two directions of the plane direction and the vertical direction, the interference of the air holes 51 and 61 is achieved. A synergistic effect of (overlapping in plan view) and compression of the cushion material 90 is exhibited.
On the other hand, the cushion material 90 may not be positively compressed, but may be used to prevent the air in the cabinet from leaking to the periphery by lightly contacting the upper plate 50 or confronting it through a narrow interval.

[Embodiment 6]
FIG. 21 is a side view and a partial perspective view schematically illustrating the chute of the vending machine according to the sixth embodiment of the present invention. In the following description, the same parts as in FIG. 1 are denoted by the same reference numerals in the last two digits, and a part of the description is omitted.
In FIG. 21, the upper plate 950 and the lower plate 960 of the chute 940 are provided with circular vent holes 951 and 961 at the same pitch, respectively. A cylindrical projection 962 is provided around the ventilation hole 961 of the lower plate 960 toward the upper plate 950. Since the upper end surface of the cylindrical projection 962 is in contact with or close to the lower surface of the upper plate 950, the air inside the chamber is between the upper plate 950 and the lower plate 960, and the side edge portion of the adjacent vent or chute 940. There is no leakage.

The method for forming the cylindrical projection 962 is not limited, and when the vent hole 961 is formed by blanking or the like, the periphery of the vent hole 961 is bulged in a throttle shape so as to have a predetermined height (burring). Even in this case, a separately formed cylindrical body may be bonded so as to surround the vent hole 961.
Further, instead of the cylindrical projection 962 provided on the lower plate 960, a cylindrical projection having a similar shape may be provided on the upper plate 950 toward the lower plate 960.

Further, holding portions 952 and 953 are provided on the front side and the back side of the lower surface of the upper plate 950, respectively, and the front and back side edge portions of the lower plate 960 are held on the holding portions 952 and 953, respectively. Relative movement is possible. Further, when the lower plate 960 is constituted by a plurality of small plate materials (see Embodiment 2), the holding portions 952 and 953 may be additionally installed for each of the plurality of small plate materials.
Note that a cushion material (see FIG. 20) may be further provided between the upper plate 950 and the lower plate 960 so that the inside air does not leak from the upper end surface of the cylindrical protrusion 962.

[Embodiment 7]
FIG. 22 is a side view schematically illustrating relative moving means for relatively moving the plate material constituting the chute of the vending machine according to the seventh embodiment of the present invention.
In FIG. 22, a drive motor 101 is installed on the floor surface of the product storage chamber 10, and a drive spline shaft 102 (disposed parallel to the moving direction of the lower plate 60) is connected to the drive shaft of the drive motor 10. . On the other hand, a spline bearing 103 is disposed on the lower surface of the lower plate 60, and the drive spline shaft 102 is screwed to the spline bearing 103. Therefore, if the drive spline shaft 102 is rotated forward or backward, the lower plate 60 moves forward or backward, and thus acts as a lower plate translation means. Further, if the drive motor 101 and the spline bearing 103 are installed so as to be able to rotate (rotate) and the lower plate 60 is installed so as to be able to rotate (revolve), it acts as a means for rotating the lower plate. Further, if a part of the lower plate 60 is fixed, it also acts as a deformation means.
The drive motor 101 may be a stepping motor, and the movement position or deformation amount of the lower plate 60 may be finely controlled. Furthermore, the relative movement means and the deformation means of the present invention are not limited to this, and an electric cylinder or a rack / pinion mechanism may be installed. Moreover, you may fix to the upper board instead of installing the drive motor 101 on a floor surface.

  INDUSTRIAL APPLICABILITY The present invention can be widely used as a means for equalizing product temperatures and measures for reducing power consumption in vending machines that sell products by cooling or heating them.
