[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a method for inspecting a temperature control function of a temperature control device of a vending machine that performs a temperature control operation of at least one of a cooling operation and a heating operation on a product stored in a warehouse.
[0002]
[Prior art]
As shown in FIGS. 8 and 9, in a vending machine that sells hot beverages and cold beverages, an insulated inner box 3 is provided in a vending machine main body 1 that supports the front door 2 so that it can be opened and closed. There are provided an interior 4 in which a heat insulation space is formed to store a large number of products, and an exterior 5 that is disposed in the lower part of the vending machine main body 1 and has an air circulation to the outside instead of the heat insulation space. . The front side of the inner box 3 can be opened and closed by an inner door 6, and the inner box 3 is partitioned by an inner partition wall 7 extending vertically to form a plurality of interiors 4. Reference numeral 8 denotes a chute for guiding the stored product to the product outlet 2a through the inner box opening 6a.
[0003]
In each chamber 4, there is a sheathed heater 11 for heating the chamber 4, an evaporator 12 for cooling the chamber 4, and a blower for sending warm air and cold air from the sheathed heater 11 and the evaporator 12. The internal unit 10 including the fan 13 and the like is arranged as a unit on the internal unit base 14. The outside 5 includes one compressor 21, one condenser 22, an exhaust heat fan 23 for blowing heat to the condenser 22 and exhausting heat to the outside, and a plurality of solenoid valves 24. The unit 20 is arranged in a state assembled on the external unit base 25.
[0004]
In addition, each capillary tube 31 that connects the electromagnetic valve 24 and the evaporator 12 is disposed in a portion after passing through the heat insulating structure portion from the outside 5 to the inside 4, the through portion, and the like. Return pipes 32 for returning the refrigerant are gathered outside the cabinet 5 and connected to the compressor 21.
[0005]
When the product in the refrigerator 4 is a cold beverage, the evaporator 12 is driven by driving a refrigeration cycle including the compressor 21, the condenser 22, the evaporator 12 and the like without the sheathed heater 11. The cooling air is sent to the inside 4 by the blower fan 13 to cool the product. On the other hand, when the product in the refrigerator 4 is a hot beverage, the sheathed heater 11 is operated by operating the sheathed heater 11 in a state where the solenoid valve 24 is turned off and the refrigerant is not sent to the evaporator 12. The product is warmed by sending the warm air around to the interior 4 by the blower fan 13. In this manner, by cooling or heating the interior 4 of each cabinet, the temperature is adjusted to a temperature suitable for hot beverages and cold beverages.
[0006]
When assembling the temperature control device having the above-described conventional configuration to the vending machine body 1, the bottom surface of the vending machine body 1 is fixed after the inner box 3 is fixed to the vending machine body 1 (the chute 8 is not attached). Assembling work of the external unit 20 such as the compressor 21, the condenser 22, and the exhaust heat fan 23 on the upper surface of the unit, and the evaporator 12 on the upper surface part of the bottom surface of the inner box 3 corresponding to each internal 4 The assembly work of the in-compartment unit 10 including the sheathed heater 11 and the blower fan 13 and the pipe assembly work of the capillary tube 31 and the return pipe 32 are performed.
[0007]
Specifically, as shown in FIG. 10, prior to the assembly work, one outside unit 20 and a plurality of inside units 10 in the inside 4 are previously connected to the capillary tube 31 and the return pipe. The external unit 20 and the internal unit 10 are inserted into the vending machine main body 1 at the same time, and the assembling work is performed. That is, the outside unit 20 places the unit base 25 assembled with each component on the upper surface of the bottom surface of the vending machine main body 1, for example, a guide rail (see FIG. The units 10 and 20 are arranged by being pushed in with the hand little by little while being along the line (not shown), and being pushed in while being supported by the hand so that the position does not shift. The inside unit 10 and the outside unit 20 are not easily reachable at the back side of the placement location and cannot be screwed, so the front side of each unit 10, 20 is relatively easy to insert and hold by fitting. Is fixed with screws. In addition, the rubber packing etc. are applied to the back part of each unit 10 and 20 for vibration isolation.
[0008]
Further, when the units 10 and 20 are pushed into the interior 4 and the exterior 5, the capillary tube 31 and the return are provided in the notch 3 a formed at the front end of the bottom surface of the inner box 3 in advance corresponding to the interior 4 space. After the piping 32 is inserted, in order to prevent heat leakage from the interior 4 to the exterior 5, the notch 3 a is closed with a putty, and this portion is covered with a gasket 9 or the like to be airtight with the inner door 6. I try to keep sex.
[0009]
[Problems to be solved by the invention]
However, when the temperature control device having the above-described conventional configuration is assembled to the vending machine main body 1, after the inner box 3 is fixed to the vending machine main body 1, as described above, the upper surface of the bottom surface of the vending machine main body 1 is used. Assembling work of the external unit 20 such as the compressor 21, the condenser 22, and the exhaust heat fan 23, and the evaporator 12 and the seeds on the upper surface of the bottom portion of the inner box 3 corresponding to each internal 4 Since each assembly operation of the in-compartment unit 10 including the heater 11 and the blower fan 13 and the like, and the assembly operation of the capillary tube 31 and the return pipe 32 must be performed, a narrow place (particularly the outside unit 20). Is a narrow space 5 between the bottom of the inner box 3 and the bottom of the vending machine main body 1), and requires a lot of mounting work or piping work. Many hands for assembly work And or it takes a long time, during assembly work, the failure cause by, for example, scratching, such as a capillary tube 31 and the return pipe 32 there or to occur.
[0010]
Further, even when the capillary tube 31 or the return pipe 32 was damaged, it was not known that it was defective until all the temperature control devices were assembled, the power source was connected, and the operation was started. Since the capillary tube 31 and the return pipe 32 are extended to the position outside the bottom surface portion of the inner box 3, the capillary distance of the capillary tube 31 and the return pipe 32 has to be increased.
[0011]
In addition, the compressor 21 disposed outside the vending machine 5, the electrical components provided in the compressor 21, the exhaust heat fan 23, etc., have rain water intruded from the outside or heavy rain and the lower part is When immersed in water, these parts may fail and need to be replaced. However, in the above-described conventional configuration, the internal unit 10 and the external unit 20 are integrally connected in a state where they cannot be separated from the vending machine body 1 via the capillary tube 31 and the return pipe 32. . Therefore, at the time of replacement, it is unavoidable to take out and replace each internal unit 10 or external unit 20 from the vending machine main body 1 in the reverse order of the above assembling work. It took time and work efficiency was bad.
[0012]
In addition, it is difficult to check the actual cooling performance and heating performance in advance in the manufacturing process of the vending machine with the temperature controller alone, so the cooling performance is only after the temperature controller is assembled. It was not clear that the heating performance was poor, and the work efficiency was poor.
[0013]
Further, since the compressor 21 and the exhaust heat fan 23 are attached to the upper surface of the bottom surface of the vending machine body 1, vibrations during operation from the compressor 21 and the exhaust heat fan 23 are generated in the vending machine body 1. It is easy to transmit to the case, and as a result, there is a risk that noises and vibrations such as a roaring sound will leak around the vending machine. Moreover, since the internal units 10 and the external units 20 are respectively fixed only on the front side and only the rear side is fitted, the compressor 21, the exhaust heat fan 23, the blower fan 13, etc. Noise and vibration during operation were also likely to increase.
[0014]
The present invention solves the above-mentioned problems, can efficiently perform the assembly work to the vending machine body, can easily find the defective state even if there is a defect in the piping, repair Work and parts replacement work can be done efficiently, actual cooling performance and heating performance can be checked in advance independently, and further, due to vibration during operation from the compressor and exhaust heat fan It is an object of the present invention to provide a temperature control function inspection method for inspecting the temperature control function of the temperature control device of a vending machine that can reduce the leaking of a roaring sound and the like around the vending machine.
[0015]

[0026]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, a vending machine according to an embodiment of the present invention will be described with reference to the drawings. Components having substantially the same functions as those of a conventional vending machine are denoted by the same reference numerals and description thereof is omitted.
[0027]
As shown in FIGS. 1 and 2, in this vending machine, a base portion 50 that partitions the inside 4 and the outside 5 and forms the bottom surface of the inner box 3 is formed inside the side surface 1 a of the vending machine body 1. It is configured to be detachable from the vending machine main body 1 via a guide rail 51 attached to the vending machine. For example, the base portion 50 has a structure in which a heat insulating material 52 is sandwiched from above and below by a metal plate 53 and the periphery thereof is connected by a joint material 54 such as a synthetic resin having heat insulating properties. Is difficult to be transmitted to the lower surface side. The base portion 50 may be configured by injecting a foam material after the upper and lower metal plates 53 are combined with the joint material 54.
[0028]
On the upper surface of the base portion 50, the in-compartment units 10 including the sheathing heater 11 for heating, the evaporator 12 for cooling, the fan 13 for blowing, and the like are respectively assembled corresponding to the insides 4. . On the lower surface of the base portion 50, an external unit 20 including a compressor 21, a condenser 22, an exhaust heat fan 23, a plurality of electromagnetic valves 24 and the like is assembled. Further, the base portion 50 is substantially provided with a through hole 50a through which a connecting pipe portion to each capillary tube 31 connecting each electromagnetic valve 24 and the evaporator 12 and a return pipe 32 for returning the refrigerant from each evaporator 12 is passed. Each cooling component (evaporator 12, compressor 21, condenser 22, etc.) is formed by connecting pipe portions to the capillary tubes 31 that are passed through the through holes 50a, return pipes 32, and the like. ) Are connected to form a refrigeration cycle.
[0029]
The guide rail 51 is formed so as to extend in the front-rear direction, and is attached to the inside of both side surfaces 1 a of the vending machine body 1. The guide rail 51 is made of, for example, a synthetic resin material having a heat insulating property on the inner surface side, and a material that absorbs vibration, such as a synthetic rubber, is fixedly formed on the outer surface of the guide rail 51. Moreover, the part above the base part 50 in the side surface and back surface of the vending machine main body 1 is made into the heat insulation structure.
[0030]
Moreover, in the state which attached the base part 50 which assembled | attached each internal unit 10 and the external unit 20 to the vending machine main body 1, and formed the inner box 3, the inside of the inner box 3 is made into the several inside 4 The partition wall 52 in the store | warehouse | chamber to partition is inserted, and it is comprised so that each store | warehouse | chamber 4 may be in the heat insulation state.
[0031]
In the above configuration, when assembling the temperature control device including the in-compartment unit 10 and the out-of-compartment unit 20 to the vending machine main body 1, the in-compartment unit 10 and the out-of-compartment unit with respect to the single base unit 50. 20 is attached in advance. That is, the base unit 50 that is not assembled in the vending machine, the external unit 20 including the compressor 21, the condenser 22, the exhaust heat fan 23, the plurality of electromagnetic valves 24, and the like, and the sheathing heater 11 for heating. Each of the internal units 10 composed of the evaporator 12 for cooling, the fan 13 for blowing, and the like are respectively attached, the connecting piping part to the capillary tube 31 and the return piping 32 are passed through the through holes 50a of the base part 50, Connect cooling components. And the base part 50 which assembled | attached and integrated the unit 20 outside the store | warehouse | chamber and the unit 10 in this way is inserted between the guide rails 51 of the vending machine main body 1, and is assembled | attached. Thereafter, the internal partition walls 52 that partition the interior of the inner box 3 into a plurality of interiors 4 are inserted, and each interior 4 is brought into an adiabatic state, whereby the assembly of the temperature control device is completed.
[0032]
According to this configuration, since the internal unit 10 and the external unit 20 may be assembled to the single base unit 50, the internal unit 10 is attached to the vending machine main body 1 to which the inner box 3 is attached as in the conventional case. Compared to the case where the outside unit 20 is assembled, there is no work space limitation and the inside unit 10 and the outside unit 20 can be efficiently assembled to the single base unit 50. When the internal unit 10 and the external unit 20 are assembled to 50, they are collected as one large unit body. In addition, since the base unit 50 assembled with the internal unit 10 and the external unit 20 can be attached to the vending machine main body 1 simply by inserting it between the guide rails 51, the entire assembly operation can be performed. It can be done efficiently with little effort and time.
[0033]
In addition, when the temperature control device breaks down, the base unit 50 in which the internal unit 10 and the external unit 20 are assembled can be easily taken out from the vending machine main body 1 as one unit body. It is possible to easily and efficiently replace or repair the component parts of the apparatus, and it is possible to minimize damage to the piping and the like during removal.
[0034]
Furthermore, since the external unit 20 is assembled to the base unit 50, the distance between the internal unit 10 and the external unit 20 becomes shorter than before. The internal unit 10 and the external unit 20 can be assembled into the base unit 50 in advance to form a unit, the base unit 50 can be freely processed, and a through-hole 50a for piping can be provided. As described above, the through hole 50a is provided in the base portion 50, and the electromagnetic valve 24 and the evaporator 12 are linearly connected by the capillary tube 31, or the return pipe 32 from the evaporator 12 to the compressor 21 is linearly connected. Can be arranged. For these reasons, the length of the pipe at the connecting portion can be made shorter than before, the cost of parts of the piping equipment can be reduced, and the pipe assembly work is also improved.
[0035]
Further, since the external unit 20 is assembled to the base unit 50, the compressor 21, the exhaust heat fan 23, and the like of the external unit 20 are directly assembled to the vending machine main body 1 as in the past. Compared to the case, vibration during operation from the compressor 21 and the exhaust heat fan 23 becomes difficult to be transmitted to the case of the vending machine body 1, and noise and vibration such as a roaring sound are generated around the vending machine. It becomes difficult to leak. Moreover, since each component of the external unit 20 and each component of the internal unit 10 can be securely fixed to the base portion 50 by screwing or the like, generation of noise and vibration itself can be suppressed. Further, since the vibration absorbing material is fixed to the guide rail 51, vibration during operation from the compressor 21 and the exhaust heat fan 23 is more difficult to be transmitted to the case of the vending machine body 1, and noise and vibration are reduced. Can be more reliably prevented from leaking around the vending machine.
[0036]
Next, FIGS. 3 and 4 relate to another embodiment of the present invention. In the temperature control device of this vending machine, the interior of each cabinet at the rear portion of the base portion 60 forming the bottom surface portion of the inner box 3 is shown. 4 are respectively formed in the recesses 61 that are recessed downward. In each recess 61, a heating sheath heater 11, which is the internal unit 10, a cooling evaporator 12, and a blower fan (cross flow) are formed. Fan) 13 is provided. Moreover, the compressor 21 is arrange | positioned horizontally, and it is suppressed so that the installation space height of the unit 20 outside a warehouse may not increase, forming the recessed part 61 in the base part 60. FIG. Reference numeral 62 denotes a duct that guides cool air and hot air sent from the blower fan 13 to the interior 4 satisfactorily.
[0037]
By configuring in this way, the protruding part of the in-compartment unit 10 in the space in the warehouse 4 can be almost eliminated, and the product storage space in the warehouse 4 can be increased by that much, so the number of goods stored can be reduced. It can be increased.
[0038]
FIG. 5 relates to still another embodiment of the present invention. In this vending machine, the base portion 60 forms the ceiling portion of the inner box 3, and is formed on the lower surface side of the base portion 50. The internal unit 10 is disposed, and the external unit 20 is disposed on the upper surface side of the base portion 50. An outside 5 'space is also provided above the base 50, and the outside unit 20 is provided at this location, while the lower space of the chute 8 in the inside 4 and the lower end of the vending machine main body 1 are provided. In the exterior 5 provided in the section, an electrical component group, various attachments, instruction manuals, installation fixing brackets, and the like that are conventionally provided on the back side of the front door 2 are provided. Along with this, on the back side of the vacant front door 2, lighting parts for display samples are arranged, or used as a poster display space that is wider than before.
[0039]
Further, in the conventional configuration, when the lower side of the vending machine body 1 is immersed in water due to, for example, water damage, the external unit 20 such as the compressor 21 may be damaged. Since the outer unit 20 is arranged at the upper part of the vending machine main body 1, the outside unit 10 is prevented from being immersed in water, and the outside unit 10 such as the compressor 21 can be prevented from being damaged. FIG. 5 shows the case where the temperature control device having the configuration shown in FIGS. 3 and 4 is applied. However, the temperature control device is not limited to this, and the temperature control device having the configuration shown in FIGS. 1 and 2 is used. It goes without saying that the device may be applied.
[0040]
6 and 7 are diagrams for explaining a method of inspecting the temperature control function of the temperature control apparatus described above. As shown in these figures, in this temperature control device, as in the past, even if the temperature control device is not assembled to the vending machine main body 1 and connected to a power source to operate, it can be simplified by the following method. The temperature control function can be inspected and measured automatically.
[0041]
That is, as shown in FIGS. 6 and 7, a rear panel 71, a top panel 72, a side panel 73, a partition wall panel 74, and a front panel 75, which are similar to the dimensions of an actual vending machine, are combined. Similar to the inner box 3 of the vending machine main body 1 by inserting and assembling the base portion 50 assembled with the internal unit 10 and the external unit 20 between the guide rails 51 previously attached to the plate panel 73. The inside dimensions can be easily obtained. Therefore, in this state, the temperature control device is operated to measure the temperature in each chamber 4 (for example, the temperature measuring unit is inserted for a predetermined time and a temperature sensor is attached to each chamber 4). Thus, the cooling / heating function in each chamber 4 can be inspected or measured.
[0042]
In this case, the specification of the vending machine in which the temperature control device is mounted (for example, whether the interior 4 has 3 rooms or 4 rooms, and the product storage device to be mounted is 5 in the front-rear direction). Depending on whether it is a type that has become a series or a type that has 6 series, etc., dimensions such as width and depth are summarized in several types, so that it will be a large dimension that can cover all these specifications, By creating the back panel 71, the front panel 75, and the like, the number of panels to be created can be minimized, and the component cost can be reduced.
[0043]
By adopting the inspection method as described above, it is possible to check in advance whether or not the temperature control device has failed, actual cooling performance, and heating performance alone in a manufacturing process line or the like. In addition, by using this inspection method at the development or trial production stage of the temperature control device, the development period can be shortened and the development cost can be reduced.
[0044]
In the above embodiment, the base portions 50 and 60 have a structure in which the heat insulating material 52 is sandwiched from above and below by the metal plate 53 and the periphery thereof is connected by the joint material 54 having heat insulating properties. For example, instead of the metal plate 53, a resin having rigidity may be used. Moreover, when the heat insulation partition wall which assembled | attached the internal unit 10 and the external unit 20 is the base parts 50 and 60 which consist of the bottom face part of an inner box, or the heat insulation partition wall is the base part 60 which consists of the ceiling surface part of an inner box. Although a certain case has been described, the present invention is not limited to this, and a heat insulating partition wall that partitions the interior 4 and the exterior 5 (for example, the partition such that the interior 4 and the exterior 5 are arranged in the front-rear direction and the lateral direction). It is sufficient if it is a heat insulating partition wall).
[0045]
In the above embodiment, the case where the vibration absorbing material is fixed to the guide rail 51 has been described. However, the present invention is not limited to this, and the rail sliding contact portion that makes sliding contact with the guide rail 51 or the guide rail 51 or rail sliding is described. A vibration-absorbing material may be used at a location that supports the contact location. As described above, since the external unit 20 is assembled to the base portion 50 without using a vibration absorbing material, the operation from the compressor 21 and the exhaust heat fan 23 is compared with the conventional structure. It is difficult to transmit the vibration at the time to the case of the vending machine main body 1, and noise and vibration such as a beat noise are hardly leaked around the vending machine.
[0051]
【The invention's effect】
