An opening / closing door 54 is provided on the front surface of the ice storage 12 in the ice making machine main body 10 so as to be openable and closable, and by opening the opening / closing door 54, the ice block can be taken out from the ice storage 12. .

(Regarding Ice Making Mechanism) Above the inside of the ice making machine main body 10, an ice making mechanism 32 including an ice making chamber 26, a water tray 28, an ice making water tank 30 and the like is arranged. That is, an ice making chamber 26 defining a large number of downwardly opening ice making chambers (not shown) is formed on the lower surface of the mounting frame 34 horizontally arranged above the inside of the main body 10 via a plurality of bolts 25. It is installed in. On the upper surface of the ice making chamber 26, an evaporation pipe 36 led out from the freezing mechanism 22 is closely arranged in a meandering manner so that a refrigerant can be circulated during the ice making cycle to forcibly cool the ice making chamber. In addition, the ice making chamber 26 has a detection element such as a thermistor that detects the production of ice cubes in the ice making chamber.
38 are provided.

(About water tray tilting mechanism) Further, the support plate 40 is suspended and fixed to the mounting frame 34, and the water tray 28 and the ice making water tank 30 which are integrally configured are pivotally supported by the support plate 40 in a cantilever manner to make ice. It is located directly below the chamber 26. That is, the water tray 28 is horizontally positioned during the ice making cycle, closes the ice making compartment from below, and is biased by the guard motor 42 fixed to the mounting frame 34 during the deicing cycle and tilts obliquely downward to open the ice making compartment. To do. Then, the ice cubes falling from the ice making compartment slide down on the inclined surface of the water tray 28, and are collected and stored in the ice storage 12.

(Regarding Ice Making Water Circulation Type) A pump motor 44 is disposed on the side of the ice making water tank 30 as shown in FIG. 12, sucks the ice making water stored in the tank 30, and through a pipe body (not shown). It is pumped to the water tray 28. In addition, the water tray 28 is provided with a large number of fountain holes for jetting ice making water and returning holes (none of which are shown) for collecting unfrozen residual water corresponding to the small ice making chambers. . Therefore, the ice-making water pumped to the water tray 28 by the pump motor 44 is correspondingly injected and supplied from the many fountain holes provided in the water tray 28 into the corner ice-making small chambers, so that the ice-making small chambers are cooled. Generate ice cubes.

An ice storage detection switch (not shown) is arranged on the mounting frame 34 so as to face the inside of the ice storage 12, and the ice storage operation is detected by detecting that the ice storage 12 is full of ice cubes. It is configured so that it can be stopped. Further, a drainage tray 46 is disposed inside the ice making machine main body 10, and the ice making residual water discharged from the water tray 28 and the ice making water tank 30 during the deicing cycle is collected in the drainage tray 46 and the drain pipe 48 is connected. It is released to the outside of the aircraft via. The water tray 28
A water supply pipe that is connected to an external water supply system and supplies ice-making water is provided above, and the ice-making water is supplied by controlling a solenoid valve 50 provided in the water supply pipe.

(Electrical equipment and electric parts) As shown in FIG. 12, the electrical equipment board 24 mounted on the bottom plate 16 of the ice making machine main body 10 includes a control circuit typified by a microcomputer for controlling the operation of the entire ice making machine and a compression machine. A capacitor and a fuse for starting the machine 20, other electric parts such as a starting capacitor for the geared motor 42, a starting capacitor for the pump motor 44, and a starting relay (none of which are shown) are incorporated. And the main motor of the compressor 20 that constitutes the refrigeration mechanism 22,
Wiring to each electric component such as a fan motor (not shown) is directly made from this electric component board 24.

Further, each lead wire 52 derived from an electrical component represented by the geared motor 42 and the pump motor 44 in the ice making mechanism 32.
As shown in FIG. 12, is wired inside the mounting frame 34 through a through hole 34b formed in the side plate 34a of the mounting frame 34.
The lead wire 52 is derived from an electric component such as a starting capacitor built in the electric board 24 and is wired inside the ice making machine main body 10, and inside the mounting frame 34, a connector 35 and a connection terminal. And so on. Further, each conductor 52 derived from the thermistor 38, the solenoid valve 50, the ice storage detection switch, etc. is also derived from a microcomputer or the like inside the mounting frame 34 via the connector 35, connection terminals, etc. in the same manner as described above to make ice. Conductor wire routed inside the machine body
It is electrically connected to 52.

The mounting frame 34 arranged at the upper part of the ice making machine main body 10 supports the heavy ice making mechanism 32, and at the same time, from the ice making chamber 26 to the water tray 28.
Since it is necessary to have a strength enough to withstand a large reaction force when forcibly peeling, is generally formed of a metal material.
Further, the ice making chamber 26 cooled by the evaporation pipe 36 is suspended and supported by a mounting frame 34 via a plurality of bolts 25. Therefore, when the ice making chamber 26 is cooled during the ice making operation, the mounting frame 34 is cooled by the bolts 25 or by the cold air generated from the ice making chamber 26 and the evaporation pipe 36.

In this case, when the opening / closing door 54 is opened to remove the ice blocks in the ice storage, the warm air outside flows into the ice storage,
This warm air stays near the ice making mechanism. Since the ice making chamber 26, the evaporation pipe 36, the refrigerant pipe, and the like are kept at a low temperature, when the water in the warm air comes into contact with these members, dew condensation occurs and grows as frost. Further, since the mounting frame 34 is also at a low temperature due to heat conduction from the ice making chamber 26 and the like, dew condensation also occurs on the mounting frame 34, but since it is higher than the ice making chamber 26 and the evaporation pipe 36, The condensed water becomes water drops and accumulates inside.

At this time, the conducting wire 52 wired inside the mounting frame 34
Since it is in contact with the mounting frame 34, it has been cooled to substantially the same temperature as the mounting frame 34, so that dew condensation also occurs on the surface of the conductor. As described above, the lead wire 52 derived from the electrical component
The electric wire 52 derived from an electric component built into the electric board 24, a microcomputer, or the like is connected inside the mounting frame 34.
For this reason, there is a serious problem that an electric leakage occurs due to water permeating through the connection portion (connector 35, connection terminal, etc.).

Further, when the ice making chamber 26 is being cooled by the ice making operation, when the opening / closing door 54 is closed, the water droplets accumulated in the mounting frame 34 are evaporated by the cold air transmitted from the ice making chamber 26 and the evaporation pipe 36. However, since the opening / closing door 54 is frequently opened and closed, or a predetermined amount of ice blocks is stored in the ice storage, and the ice making operation is stopped, the temperature inside the storage is increased, so that the mounting frame
It was commonplace that the water droplets generated inside 34 did not evaporate and gradually increased to form a water pool. In this case, it is pointed out that the conducting wire 52 is immersed in the water pool, which causes a leakage accident.

Therefore, the conducting wire 52 facing the inside of the mounting frame 34 is wired, for example, in a state of being held by a plurality of clamp members having one end fixed to the mounting frame 34, so that the conducting wire 52 does not come into direct contact with the mounting frame 34. It is suggested to do. However, in this case, there are disadvantages that the number of parts and complicated bundling work increase, the work efficiency decreases, and the manufacturing cost increases.

DISCLOSURE OF THE INVENTION The present invention has been proposed in order to solve the above drawbacks inherent in the support structure of the lead wire derived from various electrical components of the ice making mechanism, and to prevent the dew condensation on the lead wire. It is an object of the present invention to provide a means capable of effectively preventing the occurrence of an electric leakage accident by preventing the occurrence of electric shock and the attachment of water drops.

Means for Solving the Problems In order to overcome the above-mentioned problems and achieve the intended purpose, the present invention is to suspend and support an ice making mechanism on a holding member arranged inside an ice making machine main body.

A supporting passage and an inner bottom surface of the holding member are opposed to each other to define a passage for allowing air flow, and the supporting member is configured to support the conducting wire on the opposite side of the passage. Is characterized by.

Example Next, regarding the lead wire support structure of the automatic ice maker according to the present invention,
A preferred embodiment will be described with reference to the accompanying drawings. The same members as those described in the related art with reference to FIG. 12 are designated by the same reference numerals, and detailed description thereof will be omitted.

(Regarding the First Embodiment) FIG. 1 is a schematic perspective view of an ice making mechanism portion in an injection type automatic ice making machine in which a conducting wire support structure according to the first embodiment of the present invention is adopted. Mounting frame 34 arranged at the top
A support member 56 is provided inside the casing along the longitudinal direction of the mounting frame 34.
Is provided. As shown in FIG. 3, the support member 56 is composed of a long bottom plate 56a and side plates 56b, 56b which project at right angles along both end edges of the bottom plate 56a in the longitudinal direction.
It has a shape in cross section. And the bottom plate 56a
The side plate 56b of the side plate 56b is fixed via a plurality of fixing tools 58 in a state where a required gap is maintained between the outer bottom surface where the side plate 56b does not project and the inner bottom surface of the mounting frame 34, and this gap is a passage 57 through which the air in the refrigerator flows Function as.

That is, the support member 56 is in contact with the mounting frame 34 only through the plurality of fixtures 58, and as described later, the air inside the refrigerator is circulated in the passage 57, so that the support member 56 is circulated in the passage 57. It is configured so that the temperature can be substantially the same as the temperature of air. Further, both the support member 56 and the fixture 58 are made of a heat-defective conductive material such as a synthetic resin so that the heat conduction from the mounting frame 34 cannot be performed well. As shown in FIG. 2, a drainage hole 59 is formed in the mounting frame 34, and this drainage hole 59 functions to drain the water droplets when they are accumulated inside the mounting frame 34.

As shown in FIG. 1, the groove 56c defined by the bottom plate 56a and the side plates 56b, 56b of the support member 56 is led out from various electric components such as the pump motor 44 and the solenoid valve 50 and elements such as the thermistor 38. The conducting wire 52 wired inside the mounting frame 34 is stored and supported. That is, the conductor wire that faces the inside of the mounting frame 34.
As shown in FIG. 2, 52 is wired without contacting the bottom surface of the mounting frame 34. Therefore, as will be described later, the conductive wire 52 is not cooled by heat conduction from the mounting frame 34 to cause dew condensation on the surface thereof, nor does it come into contact with water droplets generated inside the mounting frame 34.

(Effects of First Embodiment) In the automatic ice making machine according to the first embodiment, when the ice making chamber 26 is cooled during the ice making operation, the mounting frame 34 conducts heat from the bolts 25 and the ice making chamber 26 and evaporation. It is cooled by the cool air from the pipe 36. The support member 56 and the fixture 58 are
Since each of them is composed of a heat-defective conductor, the heat conduction from the mounting frame 34 is not good, and the temperature thereof is higher than the temperature of the mounting frame 34.

If the opening / closing door 54 is frequently opened / closed in order to take out the ice blocks from the ice storage 12 in such a state, warm air flows into the storage and the temperature inside the storage rises. At this time, since the temperature of the mounting frame 34 is low, the temperature difference from the warm air is large, and dew condensation occurs on the mounting frame 34. However, the temperature of the support member 56 is higher than the temperature of the mounting frame 34, and the warm air flowing into the refrigerator flows through the passage 57 defined between the mounting frame 34 and the supporting member 56. Therefore, the temperature of the support member 56 is heated to about the same temperature as warm air. Therefore, dew condensation does not occur on the support member 56, and water does not accumulate on the groove 56c of the support member 56.

That is, since the conducting wire 52 housed and supported in the groove portion 56c of the supporting member 56 has the same temperature as the warm air flowing through the passage 57 similarly to the supporting member 56, dew condensation does not occur on the conducting wire surface. . Further, even if water is generated inside the mounting frame 34, since the conducting wire 52 is completely separated from the inner bottom surface of the mounting frame 34, water droplets do not adhere and the occurrence of an electric leakage accident is effectively prevented. be able to. Also, the support member 56
Since the plurality of conducting wires 52 housed in the groove portion 56c are integrated, it is not necessary to bundle the conducting wires 52, and there is an advantage that the binding work for the entire length of the conducting wires can be reduced.

(Regarding the Second Embodiment) FIGS. 4 to 6 show a lead wire support structure of an automatic ice making machine according to the second embodiment. As shown in the drawing, a support member 56 formed in a cross-sectional shape is provided inside the mounting frame 34.
The side plates 56b, 56b are arranged so that the open ends of the side plates 56b, 56b are in contact with the inner bottom surface of the mounting frame 34 (as shown in FIG. 5). That is, contrary to the first embodiment, the support member 56
The inner bottom surface of the bottom plate 56a and the inner bottom surface of the mounting frame 34 are opposed to each other. As a result, the support member 56 and the mounting frame 34
And the inner bottom surface of which defines a passage 57 open at both longitudinal ends.

On the inner bottom surface of the mounting frame 34, as shown in FIGS. 4 and 5, a plurality of (three in the embodiment) standing members 74 each having a shape are formed at predetermined intervals in the longitudinal direction. The fixing member 74 is positioned and fixed to the mounting frame 34 via a pin 76. The bottom plate 56a of the support member 56 has a fixing member 7
A through hole 56d is formed at a position corresponding to the standing position of 4 to allow the fixing member 74 to be inserted therethrough.
The positioning is performed by inserting the corresponding through holes 56d into the fixing member 74 provided upright on the mounting frame 34.

As shown in FIG. 5 and FIG. 6, holding pieces 74b extending in the opposite side plate direction are formed at the open ends of the side plates 74a, 74a facing each other in the fixing member 74, and project from the bottom plate 56a. A pair of side plates 74a, 74a and a pair of holding pieces 74b, 7
4b is configured to hold the plurality of conductive wires 52. It should be noted that the fixing member 74 and the pin 76 are both made of a heat-defective conductive material such as synthetic resin, and are configured to prevent good heat conduction from the mounting frame 34 via the members 74 and 76. There is.

As shown in FIG. 6, a plurality of through holes 78 are formed in the bottom plate 56a of the support member 56 in a required pattern, and air is circulated through the through holes 78. That is, since the passage 57 communicates with the outside through the longitudinal direction, both end openings, and the plurality of through holes 78, the inside air smoothly circulates in the passage 57, and the support member 56 is kept at the inside temperature. Can be kept at the same temperature. In addition to the bottom plate 56a, the side plate 56b may be provided with the through hole 78.

(Operation and effect of the second embodiment) According to the conductor support structure of the second embodiment according to this configuration, a passage that allows circulation of air in the refrigerator is provided between the inner bottom surface of the mounting frame 34 and the support member 56. 57 are defined. Further, since the support member 56 and the fixing member 74 are both made of a heat-defective conductor, the heat conduction from the mounting frame 34 cannot be performed well. Therefore, according to the structure of the second embodiment as well, the support member 56 has the same function as that of the first embodiment described above.
Since it is kept at the same temperature as the air inside the chamber circulating in the passage 57,
Even when outside warm air flows into the refrigerator due to the opening of the opening / closing door 54, it is possible to effectively prevent dew condensation on the support member 56.

In addition, the side plate 74 of the fixing member 74 is provided on the outer bottom surface of the support member 56.
Condensation does not occur on the surface of the conducting wire 52 supported via a and the holding piece 74b, and water droplets can be prevented from permeating from the connecting portion (connector 35, etc.) of the conducting wires 52, 52 and the like. . Further, since the conducting wire 52 is completely separated from the inner bottom surface of the mounting frame 34, even if a water pool is generated inside the mounting frame 34, the conducting wire 52 does not submerge in the water pool and an electric leakage accident occurs. Can be effectively prevented. Even if dew condensation occurs on the outer bottom surface of the support member 56, the dew can be dropped and discharged from the through hole 78 to the mounting frame 34 without being collected on the outer bottom surface.

(Regarding Third Embodiment) FIGS. 7 to 11 show a conductor wire support structure of an automatic ice making machine according to a third embodiment, wherein the conductor wire support structure of the embodiment is a stack-on type ice making machine. Has been adopted by. First, the schematic configuration of the stack-on type ice making machine will be described.

FIG. 7 shows the external shape of a stack-on type ice making machine. The ice making machine includes an ice making unit section 72 having an ice making mechanism 32 and a freezing mechanism 22, and this ice making unit section.
An ice storage unit section 70 is provided below 72 to form an ice storage 12 for storing the ice blocks produced by the ice making mechanism 32. It should be noted that each of the unit parts 70 and 72 is configured to be mechanically separate and independently separable, and the ice storage unit part 70 having a required capacity and the ice making unit part 72 can be arbitrarily combined. .

As shown in FIG. 8, the ice making unit section 72 is composed of an outer frame assembly 60 formed in a rectangular parallelepiped shape, and a partition plate 62 is provided at a substantially middle portion thereof.
Is installed, and the inside is divided into an ice making mechanism storage chamber and a freezing mechanism storage chamber. Between the upper vertical angle member 60a that defines the ice making mechanism storage chamber and the partition plate 62, support beams 64, 64 are erected and fixed at predetermined intervals in parallel with the horizontal angle member 60b. An ice making mechanism including an ice making chamber 26, an ice making water tank 30, and a water tray (not shown) is provided below the support beams 64, 64.
32 is suspended and supported by a plurality of bolts 25. Further, a bottom plate 16 is disposed in the refrigeration mechanism storage chamber, and a refrigeration mechanism 22 including a compressor 20, a condenser 18, a fan motor 667 and the like is stored and mounted on the bottom plate 16 and is incorporated in the ice making mechanism 32. The refrigerant can be supplied to the evaporation pipe 36 via the refrigeration mechanism 22.

The one support beam 64 is formed in a cross-sectional shape as shown in FIGS. 10 and 11, and a plurality of through holes 64b are formed in the side plate 64a on the side away from the other support beam 64. Has been done. A rectangular through hole 62a is formed in the partition plate 62 at a position where one end of the support beam 64 in the longitudinal direction abuts. Then, the conducting wire 52 led out from various electric components of the ice making mechanism 32 is introduced into the inside of the support beam 64 through the through hole 64b. Also, the electrical equipment box 24 arranged on the bottom plate 16
A conducting wire 52 derived from a built-in capacitor, a microcomputer (not shown) or the like is attached to the supporting beam 6 through the through hole 62a of the partition plate 62.
The lead wires 52, 52 are introduced into the interior of the connector 4, and are electrically connected to each other via the connector 35 and the like.

As shown in FIGS. 9 and 11, a support member 56 made of a heat-defective conductive material such as synthetic resin is provided inside the support beam 64 in which the conducting wire 52 is wired in the longitudinal direction of the support beam 64. It is arranged along. The support member 56 includes a bottom plate 56a and the bottom plate 5a.
A pair of side plates formed at right angles on both edges along the longitudinal direction of 6a
56b, 56b, and has a shape in a cross section. Further, in the third embodiment, the support member 56
As shown in FIG. 10, the two side plates 56b, 56b are fixed by appropriate fixing means (not shown) in a state where the open edge portions of the both side plates 56b, 56b are in contact with the inner bottom surface of the support beam 64. Thus, the support member 56 and the inner bottom surface of the support beam 64 define a passage 57 that opens at both ends in the longitudinal direction, and the inside air can flow through the passage 57.

As shown in FIGS. 9 and 11, on the ceiling surface of the support member 56, the through holes 64b are formed by leading out from various electric components such as the pump motor 44 and the electromagnetic valve 50 that constitute the ice making mechanism 32. The conducting wire 52 introduced through the support beam 64 is placed.
That is, the conductive wire 52 wired in the support beam 64 is a support member.
It is configured so as to contact only 56 and not conduct heat from the support beam 64. The conducting wire 52 is supported so as not to fall off from the supporting member 56 by a fixing means (not shown).

(Effects of Third Embodiment) According to the lead wire support structure of the third embodiment according to this configuration, the support beam 64 on which the ice making mechanism 32 is suspended and supported, and the support member 56 on which the lead wire 52 is placed and supported. A passage 57, through which the air in the refrigerator can flow, is provided between and. Further, since the support member 56 is made of a poorly heat-conductive conductor, the heat conduction from the support beam 64 is not good. Therefore. Even with the structure of the third embodiment, similarly to the operation and effect of the first embodiment, the support member 56 is not cooled to a low temperature, so that the conductor 52 supported by the support member 56 may be condensed. Water droplets do not adhere and it is possible to effectively prevent the occurrence of an electric leakage accident. Moreover, since the structure is extremely simple, it can be implemented at a low cost.

Although the closed cell type automatic ice making machine has been described in the illustrated embodiment, the present invention can be suitably applied to the open cell type and downflow type automatic ice making machine described above.

Effect of the Invention As described above, according to the lead wire support structure of the automatic ice making machine of the present invention, the air is provided between the support member for supporting the lead wire led out from the ice making mechanism and the holding member for suspending and supporting the ice making mechanism. Since the passage that allows the flow of the air is defined, the temperature of the support member can be made substantially the same as the temperature of the air by the air flowing through the passage. That is, even when external warm air flows into the inside of the ice maker, a large difference does not occur between the warm air temperature and the temperature of the supporting member, so that dew condensation occurs on the surface of the conductor wire supported by the supporting member. It is possible to effectively prevent an electric leakage accident without causing electric shock or water droplets.

Further, since the plurality of through holes are formed in the support member to allow the air to flow smoothly between the inside and the outside of the passage, the temperature of the support member can be quickly raised. Further, since the supporting member is made of a poorly heat-conductive conductor, the heat conduction from the holding member is not good, and the supporting member can be kept at a higher temperature than the ice making mechanism. Therefore, the temperature of the air flowing through the passage can be brought close to the support member quickly. Also, because the structure is extremely simple,
There are also advantages that the number of parts and the number of work steps are small, and the manufacturing cost can be reduced.
