2. Description of the Related Art A jet-type automatic ice making machine for continuously producing ice cubes (ice blocks) by spraying ice making water from below into a large number of ice making compartments that open downward is used in facilities such as coffee shops and restaurants. In the kitchen. The automatic ice making machine of the injection type has an ice making mechanism including an ice making chamber, a water tray, an ice making water tank, an actuator motor for tilting the water tray, a cam arm, and a number of other parts, and a mounting frame. It is arranged through. That is,
An ice-making chamber is defined horizontally below the mounting frame arranged above the inside of the housing, and has a number of small ice-making chambers that open downward. A water tray integrally provided below with an ice making water tank for storing water is pivotally supported in a cantilever manner on a water tray bracket suspended from a mounting frame via a support shaft. On the upper surface of the ice making chamber, an evaporating tube that circulates a refrigerant during the ice making operation and forcibly cools the ice making chamber is closely arranged in a meandering manner, and the ice making water is injected and supplied from the water tray into each ice making chamber. The ice making chamber is configured to generate ice cubes. Further, the mounting frame is provided with a pair of cam arms on a cam shaft rotatably supported by a bearing member suspended from the mounting frame, and an actuator motor is provided via a motor bracket. By rotating the cam arm forward and backward by the motor, the water tray can be tilted open and closed with respect to the ice making chamber.

[0003]

The ice making mechanism is composed of a number of parts as described above, and these parts are mounted on the mounting frame by screws for a water tray bracket, a bearing member, and the like.
It is mounted via a mounting jig such as a motor bracket. In this case, each part and each mounting jig are machined within a certain dimensional accuracy range, but if the dimensional variation (tolerance) of each part or each mounting jig is accumulated, the Each part cannot be mounted in a proper posture. For example, if the ice making room and the water tray are not mounted in parallel, they will come into contact during the ice making operation, which will hinder the ice making operation. Also, if the water tray or cam arm is mounted in an inclined state, the water tray cannot be tilted smoothly due to this, and the water tray cannot be held in a proper posture with respect to the ice making room. I will invite you. Therefore, when installing the ice making mechanism,
In order to improve the dimensional variation of each part and the mounting jig,
Separately, a jig for adjustment or a complicated and delicate operation for fine adjustment is required, and thus the number of parts increases and the operation time increases.

In the automatic ice making machine, since the mounting frame, the water tray bracket, the motor bracket, and the like are made of metal, the surfaces thereof are painted to prevent rust. In this case, since the ice block is a food, it is necessary to use a special paint which is harmless to the hygiene for the coating, which causes an increase in cost. Furthermore, since metal is conductive, sufficient consideration has to be given to electrical safety.

[0005]

[0023]

Next, the operation of the automatic ice maker according to the embodiment configured as described above will be described. In the ice making operation state, the ice making chamber 17 horizontally disposed on the mounting member 22 is provided.
Is closed from below by the water tray 18 disposed on the mounting member 22 so as to be tiltable. At this time, since the ice making chamber 17 and the water tray 18 are attached via the projections 28 and the bearings 31, 31 formed integrally with the attachment member 22, the two 17, 18 are accurately positioned in parallel with each other, Appropriate ice making operation can be performed. Also a water dish 18
Each of the fountain holes and the return holes drilled at the bottom face the corresponding ice making compartment.

When the ice making operation is started in this state, the refrigerating apparatus is started, and the refrigerant is circulated in the evaporating pipe 55 provided in the ice making chamber 17, so that the ice making chamber 17 is cooled.
The ice making water pumped from the ice making water tank 19 to the water tray 18 via the pump motor 33 is jetted and supplied to the corresponding ice making chamber through the fountain hole. Since the ice making chamber is cooled by the refrigerant circulating through the evaporating tube 55, ice cubes are gradually formed in the ice making chamber. Unfreezed water that has not been frozen is recovered in the ice making water tank 19 through the return hole of the water tray 18, and is returned to the pump motor 33.
For recirculation.

In the machine room 13 during the operation of the refrigerating apparatus, the external air sucked from the suction port 46 by the rotation of the cooling fan motor 15 exchanges heat with the condenser 14 and the compressor 16 to reduce the temperature. After the pressure rises, circulation is performed in which the air is exhausted from the outlets 47 and 47 to the outside. The high-temperature air (exhaust heat) generated in the machine room 13 is
As described above, it contacts a part of the first water supply pipe 48 and the second water supply pipe 51 and acts to heat tap water stored in both pipes 48 and 51.

When the ice making completion detecting means (not shown) detects that ice cubes have been generated in the ice making chamber, the operation is switched from the ice making operation to the deicing operation, and the circulation supply of the ice making water is stopped. The actuator motor 20 starts rotating. As a result, the pair of cam arms 21 and 21 rotate, and the cam surface formed at the base thereof forcibly presses the upper surface of the side of the water tray 18 downward.
Forcibly release the frozen state with. When the water tray 18 and the ice making water tank 19 are tilted to an open position where the water tray 18 and the ice making water tank 19 are tilted at a predetermined angle, the toggle lever 39a of the changeover switch 39 is switched by the one cam arm 21, and
The actuator motor 20 stops, and the tilting of the water tray 18 is stopped. At this time, the ice making water having an increased impurity concentration in the ice making water tank 19 falls from the tank open end to the drain tray 56 and is discarded outside.

By switching the changeover switch 39 described above, the hot gas valve of the refrigeration system is opened, and the compressor 16
Is circulated and supplied to the evaporating pipe 55. As a result, the ice making chamber 17 is heated, and the freezing surface between the inner surface of the ice making chamber and the ice cubes is started to melt.
When the operation is switched from the ice making operation to the deicing operation, ice is frozen on the surface of the water tray 18, the fountain holes, the return holes, and the like. There is a possibility that a cloudy ice may be generated due to a hindrance to the jetting, or the ice on the water tray may be sandwiched between the ice making chamber 17 to damage the water tray or the like. Therefore, in the automatic ice maker of the embodiment, the water tray 1
When the switch 8 is moved to the open position and the changeover switch 39 is switched, the water supply valve 49 is opened, and the first water supply valve 49 is opened from the external water supply system.
Water supply pipe 48, second water supply pipe 51, and sprinkler pipe 44
Tap water is supplied to the upper surface of the water tray 18 as washing water for melting the ice via the.

The tap water stored in a part of the first water supply pipe 48 and the second water supply pipe 51 is heated by heat exchange between the tap water and the high-temperature air in the machine room 13. When the heated high-temperature tap water is supplied onto the water tray 18, the ice frozen on the surface of the water tray, the fountain hole, the return hole, and the like is reliably melted in a short time. That is, during the next ice making operation, the ice making water is not sprayed smoothly from the fountain holes, and white turbid ice is generated.
It is possible to prevent the water tray or the like from being damaged by sandwiching ice between the water tray 7 and the water tray 18. In addition, since ice is melted with heated tap water, the amount of tap water (wash water) required for washing can be reduced, and water can be saved. Outside temperature
Since the time required for cleaning does not depend on (temperature of tap water), the time can be kept constant in summer and winter. Further, in the embodiment, since the water supply valve 49 is disposed on the front side in the machine room 13, there is an advantage that maintenance due to clogging of the water supply valve 49 can be easily performed from the front side of the machine.

The first water supply pipe 48 and the second water supply pipe 48
The water supply pipe 51 is cooled by room temperature tap water newly supplied from the external water supply system after the heated tap water (pooled tap water) is completely supplied, so that the water supply pipe 51 can be used for the next ice making operation. Tap water (ice making water) supplied to the ice making water tank 19 does not become warm. Moreover, both pipes 48,5
In a state where tap water is flowing through the apparatus, heat exchange between the heated air and the tap water hardly occurs even if the refrigeration apparatus is operated, which may affect the ice making operation. Absent.

When the circulation of the hot gas in the evaporating tube 55 elapses and the ice making chamber is heated to a certain extent, the icing between the wall of the chamber and the ice cubes is released, and the ice cubes are tilted by their own weight. To the water tray 18 at the open position where the water
Is guided along the ice storage room 12 and collected. When all of the ice cubes have separated from the ice making compartment, the ice making compartment 17 is placed in the evaporating tube 55.
The temperature rises at once due to the hot gas circulating in the air.
When the deicing completion detecting means (not shown) detects this temperature rise, the deicing operation is completed and the operation shifts to the ice making operation. That is, the actuator motor 20 rotates in the reverse direction to rotate the cam arms 21 and 21 in the reverse direction, and the arms 21 and 21 and the water tray 1 are rotated.
8 tension coil springs 38, 3
8, the water tray 18 and the ice making water tank 19 are rotated and urged to return to the horizontal closed position, thereby closing the ice making chamber of the ice making chamber 17 again from below. As described above, the actuator motor 20 for tilting the water tray 18,
The cam shaft 37 and the pair of cam arms 21, 21 are integrally formed with the support portion 35 and the bearing leg 3 formed integrally with the mounting member 22.
6, the components 20, 37, and 21 are accurately positioned with respect to the mounting member 22, and the water tray 18 can be smoothly tilted in an appropriate posture.

When the toggle lever 39a of the changeover switch 39 is switched by the reversely rotating cam arm 21, the water supply valve 49 and the hot gas valve are closed, and supply of tap water and hot gas is stopped to make ice. The operation is resumed, and the above operation is repeated. When the ice making operation and the deicing operation are repeated and a predetermined amount of ice cubes are stored in the ice storage chamber 12, the ice storage detection switch 42 detects this through the ice storage detection lever 40, and the operation of the ice making machine is started. Stopped. Since the ice storage detection lever 40 and the ice storage detection switch 42 are attached to the holder 41 and the set hole 43 formed integrally with the attachment member 22, both parts 40, 42 are positioned with high precision with respect to the attachment member 22, Ice storage can be accurately detected.

In the automatic ice making machine of the embodiment, the mounting member 22 for mounting the ice making mechanism 11 to the housing 10 is provided by the ice making chamber 17, the water tray 18, the actuator motor 20 and the like constituting the ice making mechanism 11. Since the mounting receiving portion for disposing is made of synthetic resin integrally molded, the mounting accuracy of each component is improved, and the ice making operation and the deicing operation can be performed properly. That is, the dimensional variation (tolerance) of each part
Can be minimized, and the installation time of the ice making mechanism 11 can be shortened by using an adjustment jig or a complicated and skillful operation for performing fine adjustment. Further, since the components of the ice making mechanism 11 are directly mounted on the mounting member 22 without using a mounting jig, the number of components can be reduced and the cost can be reduced. Furthermore, since the mounting member 22 is made of a synthetic resin, it is not necessary to apply a special and expensive paint for rust prevention. Can provide.

Since the mounting member 22 of the embodiment is provided with a plurality of reinforcing ribs 26 and 27, the warpage after molding of the synthetic resin mounting member 22 can be suppressed, and the dimensional accuracy can be more preferably maintained. Can be. Further, by providing the mounting receiving portions of the components constituting the ice making mechanism 11 on the vertically extending wall portion, the load, impact, and stress of the heavy object can be received by the entire mounting member 22 and the reinforcing member can be used for reinforcement. The ribs 26 and 27 can be kept to the minimum necessary to improve moldability and reduce material cost. By the way, the conventional mounting frame is shaped like a box that opens upward,
Since each mounting receiving portion is provided on the flat bottom plate along the horizontal direction, there is a problem that the bottom plate is bent when a heavy object is mounted.

Since various lead wires and external wires routed inside the mounting member 22 or electric components such as the changeover switch 39 face the upper side of the base 57 of the mounting member 22, the electric components from the ice storage chamber 12 can be prevented. It is protected from cold air, chlorine, and water scattered from the ice making room 17. Also,

The mounting member 58 according to the modification has the same basic structure as the mounting member 22 of the embodiment, but has the same basic structure. Therefore, the ice making mechanism 11 is mounted on the housing 10 via the mounting member 58. Accordingly, the same effects as those of the embodiment can be obtained, for example, the mounting accuracy can be improved, the working time can be reduced, and the cost can be reduced.

Next, FIGS. 12 to 14 show modifications of the main part of the refrigerating apparatus employed in the automatic ice maker according to the embodiment, in which hot gas from the refrigerating apparatus is supplied to the evaporating pipe. A part of the hot gas pipe 71 for supplying to the 55 is provided to the first water supply pipe 48 and the second water supply pipe 51 so as to be able to exchange heat. That is, in the example of FIG. 12, in a state where the hot gas pipes 71 are arranged in parallel with the first water supply pipe 48 and the second water supply pipe 51, the hot water pipes are fitted and inserted into a common heat insulating hose 72. Hot gas circulating through the first supply pipe 48 and the second
It is configured to exchange heat with tap water stored in the water supply pipe 51. Note that heat exchange between hot gas and tap water is also possible by soldering the first water supply pipe 48, the second water supply pipe 51, and the hot gas pipe 71 without fitting the two into the heat insulating hose 72. is there.

In the example of FIG. 13, the first water supply pipe 48
And a hot gas pipe 71 on the outer periphery of the second water supply pipe 51.
Is spirally wound and soldered, so that heat exchange between hot gas and tap water is performed. Further, in the example of FIG. 14, a hot gas pipe 71 is provided inside the first water supply pipe 48 and the second water supply pipe 51 so that heat exchange between hot gas and tap water is performed. Note that the hot gas pipe 71 is not limited to a configuration in which heat exchange is possible with both the first water supply pipe 48 and the second water supply pipe 51, and any one of the first water supply pipe 48 and the second water supply pipe 51 may be used. And a configuration in which heat exchange is performed.

By adopting the configuration shown in FIGS. 12 to 14, the washing supplied to the water tray 18 to melt ice frozen on the surface of the water tray, the fountain hole, the return hole, etc. in the deicing operation. Water can be made unnecessary. Therefore,
The operation of the related portion will be described below in relation to control.

During the ice making operation of the automatic ice making machine, the tap water stored in the first water supply pipe 48 and the second water supply pipe 51 is supplied to the machine room 13 in the same manner as in the above-described embodiment.
It is heated by the high-temperature air (exhaust heat) inside. When the operation shifts from the ice making operation to the de-icing operation and the water tray 18 is tilted to the open position, the switching of the changeover switch 39 opens the hot gas valve of the refrigerating apparatus, and releases the hot gas discharged from the compressor 16. It is circulated and supplied to the evaporating tube 55 via the hot gas tube 71. Thereby, the ice making room 17 is heated,
The melting of the frozen surface between the inner surface of the ice making chamber and the ice cubes is started. In the modified example, at this time, the water supply valve 4
9 is not opened and the first and second water supply pipes 48, 51
Is still filled with tap water. Therefore, the tap water stored in the first and second water supply pipes 48, 51 is:
Heat is exchanged with the hot gas circulating in the hot gas pipe 71 to be further heated.

When the circulation of the hot gas in the evaporating tube 55 elapses and the ice making chamber is heated to a certain extent, the icing between the cell walls and the ice cubes is released, and the ice cubes are tilted by their own weight. To the water tray 18 at the open position where the water
Is guided along the ice storage room 12 and collected. At this time, since the water supply valve 49 is in the closed state and the washing water is not supplied to the water tray 18, the ice cubes sliding down on the water tray 18 do not come into contact with water (wash water). Melting of ice cubes is prevented. The hot gas circulating in the hot gas pipe 71 is supplied to the first water supply pipe 48 and the second water supply pipe 5.
1, the temperature of the hot gas does not drop due to the heat exchange with the tap water, and the deicing ability is smaller than that of the embodiment. It does not decrease.

When the deicing completion detecting means detects that all of the ice cubes have been removed from the ice making chamber, the operation shifts from the deicing operation to the ice making operation, and the water tray 18 returns to the horizontal closed position. Is started, and the hot gas valve is closed. At this time, the water supply valve 49 is opened, and the first water supply pipe 48 and the second water supply pipe 48 heated by heat exchange with the hot air in the machine room 13 during the previous ice making operation and the hot gas during the deicing operation. Tap water stored in the water supply pipe 51 is supplied to the upper surface of the water tray 18 via the sprinkling pipe 44. Thereby, ice frozen on the surface of the water tray, the fountain hole, the return hole, and the like is reliably melted in an extremely short time. That is, during the next ice making operation, the ice making water is not smoothly sprayed from the fountain holes to generate cloudy ice, or the water tray or the like is damaged by ice sandwiched between the ice making chamber 17 and the water tray 18. It can be reliably prevented. When the water tray 18 reaches the closed position, the water supply valve 49 is closed, the supply of tap water is stopped, the ice making operation is restarted, and the above-described operation is repeated.

The tap water supplied to the water tray 18 at the initial stage when the water tray 18 returns from the open position to the closed position is discharged to the drain tray 56 from the open end of the ice making water tank 19 in the inclined position. It is supposed to be. Therefore, the heated tap water supplied to melt the ice frozen on the water tray surface, the fountain hole, the return hole, and the like is discharged to the outside without being used as ice making water in the next ice making operation. Also, after the warmed tap water (pooled tap water) of the first water supply pipe 48 and the second water supply pipe 51 is completely supplied, the normal-temperature tap water newly supplied from the external water supply system is hot. Since the supply of hot gas in the gas pipe 71 is stopped, there is no heating, and the ice making water tank 19 stores normal-temperature tap water used as ice making water. That is, the temperature of the ice making water stored in the ice making water tank 19 for the next ice making operation does not increase, and the time required for the ice making operation does not become long.

When the tap water stored in the first water supply pipe 48 and the second water supply pipe 51 is heated by hot gas as in the modified example, the operation is shifted from the ice making operation to the deicing operation and the water tray is changed. When 18 is tilted from the closed position to the open position, the wash water used solely to melt ice that freezes on the water tray surface, fountain holes, return holes, etc. may be eliminated. Therefore, it is possible to reduce the total amount of water used, to omit the water supply control of the washing water, to simplify the control system, and to reduce the cost. Further, by controlling the supply of tap water to function as washing water after the water tray 18 starts to rise, the tap water flows on the water tray 18 having a gentle gradient, so that the tap water scatters in the refrigerator. There is also an advantage that melting and arching of the ice cubes in the ice storage room 12 can be prevented without performing.

In the embodiment, the water supply valve is arranged in the machine room.
The water supply valve may be provided at a position close to the ice making mechanism.
The mounting members according to the embodiments and the modifications are molded by injection molding or compression molding.However, conditions such as securing strength, arrangement, shape, and height of reinforcing ribs for preventing warpage and bending are as follows.
It is arbitrarily set according to the molding method,
The present invention is not limited to the embodiment and the modification. Further, the parting line when the mounting member is formed by compression molding is arranged so as not to impair moldability and material properties (particularly strength). For example, the parting line is set so that the glass fiber contained in the material spreads over the whole and does not cut it.
