Description

  The present invention generally relates to a freezing and cooling apparatus that keeps the inside of a warehouse at a low temperature and uniform, and in particular, it is installed in a game facility such as a game center, and a player operates a prize gripping means such as a shovel or a crane. The present invention relates to a refrigeration / cooling apparatus used in a prize acquisition game apparatus or the like for acquiring stacked prizes.

  Conventionally, there is a prize acquisition game device as a game device installed in a game facility such as a game center. A general play method of this device is that a player piles up a prize piled in a device whose side is surrounded by a transparent board such as an acrylic board, and a player holds a prize gripping means such as a shovel or a crane inside the apparatus, such as a button or a lever. It is operated through the operation means, and is grabbed well, and the grabbed prize is moved and dropped to the insertion port set at the center or corner of the apparatus, and the prize is taken out from the prize taking-out port.

  In this prize acquisition game device, the shovel and crane, which are the prize acquisition means, have been improved to obtain prizes by air adsorption, or equipped with a magnetic force generator that generates a magnetic force that can be adjusted in strength. There is one that adsorbs a prize that is put on (Patent Document 1).

  Traditionally, stuffed animals and room-temperature preserved confectionery have been used for the types of prizes, but cold confectionery such as lacto ice has come to be used. In this case, in order to keep the space in the device at a low temperature, a low sound wind generator for generating a low sound wind is provided on the ceiling in the device, and the generated cold air is used in the device by using a cold insulation means for forming and maintaining a cold air layer. Improvements such as the formation of a circulation path that circulates at the same time were also seen (Patent Document 2).

  However, according to the applicant's investigation, the conventional apparatus is limited in performance to cool and keep the inside down to about minus 18 degrees, and there is no problem in keeping cold such as lactice with a low milk content. There was a problem that it melts in the case of ice cream with a high milk content (milk solid content 15.0% or more, of which milk fat content 8.0% or more). In addition, a temperature of approximately minus 25 degrees is desired as a temperature for keeping the ice cream premium safely for a long time.

  Furthermore, even if cold air of minus 25 degrees or less can be supplied into the device due to the performance of the conventional cooling device, it is difficult to keep the wide cold storage in the device uniformly, for example, a cold pipe on the side of the cold storage In the case of passing through, there was a problem that the temperature in the central part of the warehouse tends to rise. Therefore, even if a high-performance cooling device that can operate under a constant voltage environment is used, the performance limit of the cold insulation is about minus 18 degrees, and it is difficult to keep the inside of the refrigerator uniformly at a low temperature.

  In general, ice cream with a high milk content has a good number of bacteria per gram instead of a good taste. Therefore, use ice cream with a high milk content as a frozen dessert in a prize-playing game device according to the prior art. Then, it may cause a serious problem in quality control that it is easy to dissolve and bacteria are easy to propagate, and in order to keep these frozen desserts cold, more strict low-temperature control and keeping the temperature in the cold storage room more uniform. Cold storage management is required.

  Therefore, in the prize acquisition game device according to the prior art that cannot perform the strict low temperature management and cold preservation management as described above, the types of ice creams and dairy products that can be handled as prizes are naturally restricted, and the taste is good and the quality is good. There was also a problem in terms of enhancing the palatability as a game by providing the player with a free gift.

  In order to solve such problems, an object of the present invention is to provide cooling and cooling means that are superior to those of conventional prize acquisition game apparatuses, and to improve palatability as a game apparatus.

  The present invention is a refrigeration / cooling device configured by piping a refrigerant pipe to an inner box composed of a side part and a bottom part, and the refrigerant pipe is piped so as to partition the inner box into two or more regions. It is characterized by that. In addition, the refrigerant pipes that are piped so as to partition the inner box into two or more regions are characterized in that a heat conduction plate is attached to each partitioning portion.

  Further, the refrigerant pipe extends from the central portion of the bottom portion at a first height substantially parallel to the bottom portion and in a direction perpendicular to the side surface portion, and is bent by 180 degrees near the side surface portion to be second height from the side surface portion. And extending in parallel to the bottom part and extending toward the center part, bending a predetermined angle substantially in parallel with the bottom part in the vicinity of the center part, and extending again to the side part two or more times, for example, three or more in the inner box The partition region is provided.

  A premium acquisition game apparatus according to an embodiment of the present invention will be described below in detail with reference to the drawings.

It has come to be.

  In this way, when the transparent plate 4 is closed, a substantially sealed space is formed inside the prize game device 1, so that, for example, a pile of cold confectionery prizes is stored therein, and the cold confectionery prizes are kept at a low temperature. Even if low-temperature air or cold air is supplied by a refrigerated cooler, the structure is difficult to leak to the outside. In order to further improve the sealing performance, packing or the like may be attached or attached to the transparent plate 4 that can be opened and closed, or the peripheral portion of the base portion 2 or the ceiling portion 9.

  Next, according to FIG. 2, the prize acquisition route in the prize acquisition game apparatus 1 equipped with the refrigeration / cooling apparatus according to the present invention will be described. When the gripping means (not shown) grips the frozen dessert placed in the ice freezer (freebie storage unit) 10 and releases it on the openable premium slope 206 (position 201), the premium is opened in advance. It is received by the open / close-type premium slope 206 (position 202), and the slope 206 is gently closed after a certain time, so that the prize itself is sent to the outlet 8 without being damaged (position 203). In FIG. 2, the prize seems to fall vertically at the position 203, but the frozen dessert can be sent out slowly by providing an appropriate slope in the shooter path.

  In FIG. 3, the external appearance perspective view of the freezing and cooling apparatus 30 concerning this invention is shown. The refrigerated cooler 30 includes a refrigerated cooler (premium storage unit) 10 supported by four legs 38 erected at the upper four corners of the base 31. Thus, a hole is provided in the central portion of the inner bottom surface of the refrigerator / freezer 10, and the column portion 36 is erected therefrom. Then, just four mesh baskets 35 are arranged using the support column 36 as a guide for partitioning, and a frozen dessert such as ice cream (not shown) is arranged in each mesh basket 35. The net cage 35 is not necessarily limited to this form, and other storage cases can be used.

  In addition, a partition refrigerant pipe (partition EVA pipe) 37 is communicated with the side boundary surface between the mesh cages 35 via the internal space of the support column 36. Since the partition refrigerant pipe 37 is piped so as to communicate with each side boundary surface of the mesh basket 35, the refrigerant refrigerant pipe 37 acts to further promote the freezing / cooling effect by the evaporating pipe piped to the side surface portion of the freezing and cold storage 10. .

  In the space between the base 31 generated by the legs 38 and the refrigerator / freezer 10, a power supply unit 32, a compressor unit 33, and a condenser 34 are arranged to constitute a machine room. These devices are necessary devices for realizing the refrigeration function and the refrigeration function of the refrigeration / reservoir 30.

  FIG. 4 is an exploded perspective view for showing the configuration of the refrigerated cooler 30 according to the present invention in more detail. Single wheel casters 41 (and adjustment legs 42) are attached to the four corners below the base 31 so that the freezing / cooling device 30 or the freezing / preserving game device 1 incorporating the frozen / cooling device 30 can be easily transported.

  In addition, in order to shield the space (machine room space) between the base 31 and the refrigerator / freezer 10 where the power supply unit 32, the compressor unit 33, the condenser 34, and the like are arranged, machine room covers 43, 46, and Machine room guards 44 and 45 are attached to the side surfaces of the machine room space using locking means such as screws.

  Furthermore, partition refrigerant pipes (partition EVA pipes) 37 that are connected to communicate with the side boundary surfaces of the mesh cages 35 through the internal space of the support column 36 are sandwiched between two partition heat conduction plates 47. Yes. These partition heat conduction plates 47 efficiently transmit the cooling effect of the partition refrigerant pipe 37 into the refrigerator / freezer 10 and facilitate the positioning of the net cage 35.

  A top cover 361 is attached to the upper part of the support column 36, and a thermistor 49 used for managing the temperature inside the refrigerator is attached to the inner side surface of the freezer 10 and protected by a thermometer cover 48. Has been. Further, a drain plug 499 for realizing a drain function is provided on the inner bottom surface of the freezer 10.

  FIG. 5 is an explanatory view for explaining the structure of the inner box constituting the inside of the refrigerator / freezer 10 and the state of communication of the refrigerant pipe 54. This inner box is manufactured by bonding together two inner box side plates 51 and 52 constituting the inner box side surface and one inner box bottom plate 53 constituting the inner box bottom. Conventional techniques such as sheet metal can be applied to the structure and bonding method of each member constituting the inner box, and various variations are conceivable, but any technique will affect the spirit of the present invention. Not give.

  Then, the inner box side refrigerant pipe 54 is spirally circulated on the side surface portion of the inner box constituted by the inner box side plates 51 and 52 and the inner box bottom plate 53 as shown in the figure. With such a configuration, the refrigerant that flows in the substantially vertical direction from the refrigerant inlet 541 reaches the upper portion of the inner box side surface, changes its course by 90 degrees, and gradually spirals along the inner box side surface portion toward the inner box bottom portion. It goes around and reaches the refrigerant outlet 542. This way of circulating the refrigerant is merely an example, and if the piping is such that the refrigerant communicates uniformly with the side surface of the inner box, the inner box gradually gradually spirals along the side surface of the inner box. You may make it circulate toward upper part, and it is good also as making it communicate so that a refrigerant | coolant may advance in a meander shape with respect to upper and lower sides of an inner box side part, and an inner box side part may circulate.

  FIG. 6 is an explanatory diagram for explaining in more detail the structure of the inner box constituting the inside of the refrigerator / freezer 10 and the communication state of the partition refrigerant pipe 37. A hole 601 is provided at the center of the inner box bottom plate 53, and the partition refrigerant pipe 37 is arranged so that the refrigerant inflow path and the outflow path pass through the hole 601.

  The refrigerant follows the following flow path by the piping of the partition refrigerant pipe 37 inside the freezer 10. That is, the refrigerant flows from the refrigerant inlet 371 in a substantially vertical direction, passes through the refrigerant hole portion 601, exits the upper surface of the inner box bottom plate 53, and then changes the course by 90 degrees so as to be substantially parallel to the bottom plate 53. It travels in a direction substantially parallel to the upper surface of the inner box bottom plate 53 and perpendicular to the side surface (F1) inside the inner box so as to maintain the height H1 of the upper surface of the box bottom plate 53 (path P).

  Next, when the vicinity of the side surface (F1) inside the inner box is reached, the course is reversed by 180 degrees, and this time, the upper surface of the inner box bottom plate 53 is maintained substantially parallel to the upper surface of the inner box bottom plate 53 so as to maintain the height H1 + H2. And it advances so that it may go to the support | pillar part 36 (not shown in FIG. 6) inside an inner box (path | route Q). Subsequently, when reaching the vicinity of the column portion 36, the course is changed by 90 degrees so that the upper surface of the inner box bottom plate 53 and the upper surface of the inner box bottom plate 53 are kept substantially parallel to the upper surface of the inner box bottom plate 53 and the side surface (F2) inside the inner box. (Path R).

And it progresses so that it may go to the support | pillar part 36 inside an inner box (path | route U). Subsequently, when reaching the vicinity of the column portion 36, the course is changed by 90 degrees so that the upper surface of the inner box bottom plate 53 and the upper surface of the inner box bottom plate 53 are kept substantially parallel to the upper surface of the inner box bottom plate 53 and the side surface (F4) inside the inner box. (Path V).

  Finally, when the vicinity of the side surface (F4) inside the inner box is reached, the course is reversed by 180 degrees, and this time, the upper surface of the inner box bottom plate 53 is kept substantially parallel to the upper surface of the inner box bottom plate 53 so as to keep the height H1. And it progresses toward the support | pillar part 36 inside an inner box (path | route W), and flows out into the refrigerant | coolant exit 372 through the hole 601 again.

  In FIG. 6, the partition refrigerant pipe 37 is piped from the support column 36 so as to be perpendicular to each of the side surfaces inside the inner box, but the present invention is not limited to this. It is good also as piping so that it may extend diagonally toward the side edge part (a junction part of a side surface and a side surface. The same applies to the following embodiments.

  In FIG. 7, in addition to the arrangement of the refrigerant pipes shown in FIGS. 5 to 6, an embodiment in which the refrigerant pipes are arranged along the inner box bottom plate 53 will be described in more detail. In FIG. 7, in addition to the refrigerant pipe 54 and the partition refrigerant pipe 37, a refrigerant flow path along the inner box bottom plate 53 is realized by the inner box bottom refrigerant pipe 71. First, as shown in FIG. 5, a spiral refrigerant flow path from the refrigerant inlet 541 to the refrigerant outlet 542 is secured on the side surface of the inner box of the refrigerator / freezer 10. An inner box bottom refrigerant pipe 71 which is a refrigerant flow path along the bottom plate 53 is connected in series. That is, the refrigerant flowing in from the refrigerant inlet 371 proceeds through the partition refrigerant pipe 37 through the route shown in FIG. 6 and then further enters the refrigerant inlet 711 connected to the refrigerant outlet 372, Advancing the lower surface, it passes through the path Y and rises again to the vicinity of the inner box bottom plate 53, and this time it advances in a meander shape so as to cover (scan) the entire inner box bottom plate 53. Then, the refrigerant flows out to the refrigerant outlet 712 and proceeds to the next circulation channel.

  FIG. 8 is an explanatory diagram showing the flow path from the partition refrigerant pipe 37 described in FIG. 7 to the inner box bottom refrigerant pipe 71 more clearly. The partition refrigerant pipe 37 and the inner box bottom refrigerant pipe 71 are configured such that the refrigerant proceeds in series by connecting the refrigerant outlet 372 and the refrigerant inlet 711.

  FIG. 9 is an explanatory diagram for explaining a state in which the partition heat conduction plate 47 is attached to each of the partition refrigerant tubes 37 described in FIGS. Two partition heat conduction plates 47 are aligned with respect to the partition refrigerant pipe 37 that extends vertically from the vertical axis on which the support column 36 is erected, respectively, in the direction of the inner box side surface 4 of the freezer 10. Are attached to each other. The partition heat conductive plate 47 is made of a material having high thermal conductivity such as copper, ceramics, or metal aluminum. The temperature of the refrigerant passing through the refrigerant pipe 37 is obtained by attaching two partition heat conduction plates 47 to each of the partition portions of the partition refrigerant pipe 37 piped so as to divide the inner box into four equal parts. Can be efficiently conducted to each partition portion, so that the temperature in the freezer can be made more uniform, and the heat conduction plate 47 as the partition plate can position the mesh cage 35 better. To do.

  FIG. 10 is a cross-sectional view of the refrigerator / freezer 10 in which the support column 36, the partition refrigerant pipe 37, the top cover 361, the inner box side refrigerant pipe 54, the inner box bottom refrigerant pipe 71, and the partition heat conduction plate 47 are installed. is there. As a refrigerant path passing through the partition refrigerant pipe 37, the refrigerant flows in the substantially vertical direction from the refrigerant inlet 371, passes through the hole and exits to the upper surface of the inner box bottom plate 53, and then changes the course by 90 degrees to change the inner box bottom plate 53. So as to keep the height H1 and the upper surface of the inner box 53 substantially parallel to the upper surface of the inner box bottom plate 53 and proceed in a direction perpendicular to the side surface (F1) inside the inner box, and then near the side surface (F1) inside the inner box When it reaches, the course is reversed by 180 degrees, and this time, the upper surface of the inner box bottom plate 53 is kept substantially parallel to the upper surface of the inner box bottom plate 53 so as to maintain the height H1 + H2, and is directed to the column portion 36 inside the inner box. The state of progress is clearly illustrated.

  FIG. 11 is an explanatory diagram for explaining the structure and schematic dimensions of the partition refrigerant pipe 37. The unit of dimension is millimail. The partition refrigerant pipe 37 is composed of three members because of its structure, and the first EVA pipe 37a and the second EVA pipe 37b are connected by an L-shaped joint 37c. This is divided into the above two members (37a, 37b) for the purpose of manufacturing cost and convenience, but if the manufacturing cost is not taken into account, a seamless partition refrigerant pipe can be used, It is good also as a structure which connects 3 or more members with 2 or more couplings.

  FIG. 12 is an explanatory diagram for explaining the structure and schematic dimensions of the partition heat conduction plate 47. The unit of dimension is millimail. The partition heat conduction plate 47 includes grooves 471 and 472 for sandwiching the partition refrigerant pipe 37 and screw holes 473 for screwing the two partition heat conduction plates 47 together. As shown in the figure, in the present embodiment, H1 = 55 mm and H2 = 60 mm.

  FIG. 13 illustrates a state in which two partition heat conduction plates 47 are attached together. The two partition heat conduction plates 47a and 47b are attached so that the groove portions 471a and 472a and the groove portions 471b and 472b face each other and sandwich the partition refrigerant pipe 37, and are locked by locking means such as screws and screws. The The partition heat conduction plate 47 thus provided provides an effect of efficiently conducting the cooling effect of the partition refrigerant pipe 37 into the freezer refrigerator 10 and facilitating the positioning of the net cage 35.

  FIG. 14 shows a refrigerant circuit of the refrigeration / cooling apparatus in the embodiment of the present invention. This refrigerant circuit is a refrigeration / cooling device that constitutes a so-called refrigeration cycle, which includes a compressor 1401, a condenser 1402, a dryer 1403, capillaries 1404 and 1405, a liquid reservoir 1406, a check valve 1407, and the like.

  The flow of the refrigerant will be described along the embodiment of the present invention. First, in FIG. 14A, the refrigerant sucked into the compressor 1401 is adiabatically compressed and flows into the condenser 1402 as high-pressure gas. . The high-pressure gas entering the condenser 1402 is cooled and becomes a saturated liquid by condensation heat while maintaining an equal pressure, passes through the dryer 1403, capillaries 1404 and 1405, passes through the inner box side refrigerant pipe 54, the partition refrigerant pipe 37 and the inner refrigerant. Branches to the box bottom refrigerant pipe 71, and the refrigerated cooler 10 is refrigerated. Thereafter, the refrigerant flows into the compressor 1401 again through the liquid reservoir 1406 and the check valve 1407.

  FIG. 14B shows another embodiment in which electromagnetic valves 1408 and 1409 are installed in the refrigerant circuit of FIG. By installing electromagnetic valves 1408 and 1409 in the parallel flow paths branched into the inner box side refrigerant pipe 54 and the partition refrigerant pipe 37 and the inner box bottom refrigerant pipe 71, the inner box side refrigerant pipe 54 and The amount of refrigerant flowing into the partition refrigerant pipe 37 and the inner box bottom refrigerant pipe 71 can be adjusted. Further, the electromagnetic valve 1409 can adjust the refrigerant flow rate to the flow path (Z) that bypasses the partition refrigerant pipe 37 as well as the refrigerant quantity flowing into the partition refrigerant pipe 37 and the inner box bottom refrigerant pipe 71. Further, there is a special effect that the low-temperature management of the freezer 10 can be controlled more finely to reduce the cooling / cooling cost. The electromagnetic valves 1408 and 1409 may be electronic expansion valves (resistors) that can adjust the valve opening steplessly in addition to the on / off type. In FIG. 14B, two solenoid valves are provided (1408 and 1409), one at the branching position of the inner box side refrigerant pipe 54, the partition refrigerant pipe 37 and the inner box bottom refrigerant pipe 71. It is good also as providing only.

  FIG. 15 illustrates various ways of piping the partition refrigerant pipe 37. 15 (A) to 15 (F) are views of the inner box of the refrigerator / freezer 10 as viewed from above, and the inner boxes in FIGS. 15 (A) to (C) and (F) have a substantially circular shape. 15D and 15E are rectangular. Thus, the refrigerant flowing in from the column portion 36 follows different flow paths depending on the manner of piping of the partition refrigerant pipe 37. Since the area partitioned by each pipe is different, the variations will be described below.

FIG. 15 (A) divides the plane of the inner box of the freezer into 3 minutes. In addition, since the bottom surface of the inner box is substantially circular, three fan-shaped cages each having a central angle θ ₁ = 120 degrees are prepared so that the mesh cage 35 matches this shape. In this case, the refrigerant flow path is as follows. The refrigerant flows in the substantially vertical direction from the refrigerant inlet 371 of the support column 36 and exits to the upper surface of the inner box bottom plate. Is substantially parallel to the upper surface of the inner box and proceeds to the side surface inside the inner box (path P). Next, when the vicinity of the side surface inside the inner box is reached, the course is reversed by 180 degrees, and this time, the upper surface of the inner box bottom plate is kept substantially parallel to the upper surface of the inner box bottom plate so as to maintain the height H1 + H2. It progresses so that it may go to the support | pillar part 36 (path | route Q). Subsequently, when reaching the vicinity of the column portion 36, the course is changed by 120 degrees so as to maintain the height H1 + H2 with the upper surface of the inner box bottom plate and substantially parallel to the upper surface of the inner box bottom plate 53 and perpendicular to the side surface inside the inner box. Travel in the direction (path R). Then, when it reaches the vicinity of the side surface inside the inner box, the course is reversed by 180 degrees, and this time, the upper surface of the inner box bottom plate 53 is kept substantially parallel to the upper surface of the inner box bottom plate 53 so as to maintain the height H1. It advances so that it may go to the support | pillar part 36 (route S). When it reaches the vicinity of the column portion 36, its course is changed by 120 degrees, and it is substantially parallel to the upper surface of the inner box bottom plate and perpendicular to the side surface inside the inner box so as to keep the height H1 of the upper surface of the inner box bottom plate. (Route T). Finally, when it reaches the vicinity of the side surface inside the inner box, the course is reversed by 180 degrees, and this time, the upper surface of the inner box bottom plate and the height of the inner box bottom plate are kept substantially parallel to the upper surface of the inner box bottom plate. It progresses toward the column part 36 (path U) and flows out from the column part 36 to the refrigerant outlet 372.

FIG. 15 (B) divides the plane of the inner box of the refrigerator compartment into 6 minutes. Moreover, since the bottom of the inner box has a substantially circular shape, six fan-shaped cages each having a central angle θ ₂ = 60 degrees are prepared so that the mesh cage 35 can meet this shape. For the refrigerant flow path in this case, the six partition areas (sector shape with a central angle θ ₂ = 60 degrees) are sequentially divided so that the path turning angle when reaching the vicinity of the support column 36 is 60 degrees. Circulate to do.

FIG. 15C divides the plane of the inner box of the freezer into three parts, but it is not an equal division. In this case, the mesh basket 35 has a fan shape with a central angle θ ₃ = 60 degrees, a fan shape with a central angle θ ₄ = 180 degrees (radial shape), and a central angle θ ₅ = 180 so as to meet these shapes. A fan-shaped one is prepared. As for the flow path of the refrigerant, it is only peculiar that in the path S, even if it reaches the vicinity of the column portion 36, it passes through as it is, proceeds to the inner side of the opposite inner box and turns back 180 degrees (becomes path T). The procedure for turning back the key points is the same as in FIGS. 6, 15A and 15B, and the like.

  In addition, the unequal division of the net cage area shown in FIG. 15C can be applied to a refrigerator / freezer having a rectangular inner box plane (FIG. 15D), or Needless to say, the technical idea of the present invention can be applied to a configuration in which the net cage area is simply divided into two (FIGS. 15E and 15F).

  In the description so far, H1 can be as close to zero as possible. In this case, the refrigerant pipe over the bottom surface of the inner box is piped to the bottom surface (in some cases, it may come into contact with the bottom surface). Furthermore, in this embodiment, regarding the magnitude relationship between H1 and H2, for convenience of explanation, H1> H2, but it may be H1 <H2.

  In the embodiment described above, the processing of the refrigerant pipe for determining the refrigerant flow path is performed by a well-known bending technique such as a copper pipe or pipe bending, and the refrigerant flow path remains as it is. This is consistent with the structure of the refrigerant pipe. For example, “the refrigerant changes its path by 90 degrees” means that the refrigerant passes through the refrigerant pipe bent by 90 degrees, and its specific shape is particularly as shown in FIGS. It is. Accordingly, the processing technique itself for processing the essential parts of the refrigerant pipe particularly shown in FIGS. 5 to 11 is obvious to those skilled in the art.

  Moreover, as is clear from the various embodiments described above, according to the partition refrigerant pipe (partition EVA pipe) according to the present invention, the partition area of the inner box of the freezer can be easily changed. For example, in the case of changing from the partition region shown in FIG. 15A to the partition region shown in FIG. 15B, the partition refrigerant pipe provided with three partition regions every 120 degrees is divided into six partition regions every 60 degrees. It is only necessary to change the three refrigerant net cages having a central angle of 120 degrees to six fan net cages having a central angle of 60 degrees. If an inner box in which partitions are integrally formed is used, such a design change must be made again from a mold, which entails enormous costs. The present invention also has an effect that it can flexibly cope with such a design change.
