Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a process for immersing a large number of ice-making projections projecting from the lower surface of an ice-making substrate into ice-making water in an ice-making chamber defined inside a water tray. The present invention relates to an ice maker in which an inverted dome-shaped ice block is formed around the ice maker.

[0002]

2. Description of the Related Art As an ice making machine for continuously producing a large number of ice blocks, ice making water is stored at a required level in an ice making chamber defined inside a water tray, and protrudes from a lower surface of an ice making substrate provided with an evaporation tube. 2. Description of the Related Art There is known a water storage type ice maker in which a suspended ice making projection is immersed in ice making water to form an ice block around the ice making projection. In this ice making machine, the ice making water does not circulate at all during the ice making operation, and is kept in a so-called "stationary state", so that the ice blocks gradually formed around the ice making projections are melted into the ice making water. It becomes cloudy and opaque due to the influence of air. The fact that the obtained ice block is cloudy does not generally cause a problem with the use of ice itself for cooling, etc., but when the cloudy ice is used for eating and drinking in coffee shops and restaurants, it is transparent and clear. Compared to pure ice, the appearance is clearly inferior, and the commodity price is reduced as a whole.

Therefore, as disclosed in, for example, Japanese Utility Model Application Laid-Open No. 5-64677, a rocking plate is swingably disposed in an ice-making chamber defined inside a water tray, and an engaging portion of the rocking plate is provided. Under the action of engaging with the engaging member provided in the swinging means, by swinging during the ice making operation to move the ice making water in the ice making room, the cloudiness of the ice blocks formed around the ice making projections is reduced. Prevention has been made.

[0004]

In the ice making machine, when a complete ice block is formed on the ice making projection and the operation is switched from the ice making operation to the deicing operation, the water tray is tilted to expose the ice block. In this case, if the operation is switched to the deicing operation in a state where the engaging portion of the rocking plate and the engaging member of the rocking means are still engaged, the tilting of the rocking plate that tilts with the water tray is prevented. As a result, there is a risk that the deicing operation will be hindered. That is, when the operation mode is switched to the deicing operation, it is necessary to retract the engaging member of the rocking means from the tilt locus of the engaging portion of the rocking plate.

Therefore, in the ice making machine disclosed in the above publication, a swinging means is arranged on a mounting jig which is swingably arranged, and a switch for controlling the operation of a swinging motor for rotating the swinging means is swung. It is located below the moving means. When the water tray is facing the ice making position, the mounting jig is urged via a spring in a direction away from the switch, so that the switch is not operated by the rocking means. Then, by switching to the deicing operation and releasing the urging force of the spring when the water tray is tilted, the mounting jig is tilted by its own weight of the rocking motor, the switch is operated by the rocking means, and the rocking is performed. The swing motor is stopped at a position where the engaging member of the means is retracted from the tilt locus of the engaging portion of the swing plate. However, in this structure, when the water tray rises and returns toward the ice making position in order to shift from the deicing operation to the ice making operation, it is necessary to apply the urging force of the spring to the mounting jig again. There was a problem that the structure became complicated. Further, since the spring is engaged with the mechanism for tilting the water tray, a load is applied to the motor that drives the water tray, and there is a possibility that the motor may be damaged due to gear removal or the like.

[0006]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned drawbacks inherent in the prior art, and has been proposed in order to preferably solve the problem. An object of the present invention is to provide an ice maker having a simple mechanism capable of achieving a smooth tilt of a moving plate.

[0007]

SUMMARY OF THE INVENTION In order to overcome the above-mentioned problems and achieve the intended object, the present invention is arranged so as to be tiltable and always horizontal, and an ice making section is immersed in ice making water stored inside. A water plate, a rocking plate slidably disposed inside the water plate, and a mounting jig pivotally supported on the main body side of the ice making machine. A oscillating means which is rotatably driven by an oscillating motor provided and which oscillates between an operating position and a stop position integrally with the mounting jig; and An engaging member for reciprocating engagement and disengagement of the rocking plate with the engaging portion of the rocking plate to rock the rocking plate inside the water tray during the ice making operation is provided on the rocking means, A control unit having a notch formed at a required position in a circumferential direction; and a detection unit facing a swing locus of the control unit in the swing unit. When the engaging member of the oscillating means rotationally driven by the rotor engages with the engaging portion of the oscillating plate, the oscillating plate comes into contact with an ice block formed around the ice making section and oscillates. When a reaction force is applied to the means, the rocking means is rocked integrally with the mounting jig toward the stop position, and the control unit activates the detecting means to detect the completion of ice making and to stop the rotation. When the continuous notch of the control unit reaches the detection unit, the operation of the detection unit is released, and at this time, the swing motor is stopped and the engagement member is moved from the inclination locus of the engagement portion on the swing plate. An ice making machine configured to be stopped at a separated position, wherein the cam plate engages with the water tray, and is rotated by an actuator motor to tilt the water tray obliquely downward and to return to a horizontal position, and a cam plate; The rocker is pivotally supported by the main body of the ice making machine, A presser plate which is provided on the cam plate, and which is capable of swinging integrally with the swinging means in contact with a step, and which is engaged with the presser plate so as to be detachably engageable when the cam plate rotates, and An operating part capable of urging the swinging means toward the stop position via the mounting jig and the main body of the ice making machine, and urges the mounting jig toward the operating position. When the cam plate is rotated to tilt the water tray obliquely downward by the actuator motor when the detecting unit detects the completion of ice making, the operating unit engages with the presser plate. The swing means is held at a stop position until the notch of the control unit reaches the detection means, and when the operating part is detached from the holding plate, the swing means and the mounting jig are operated under the elastic action of the elastic means. It is configured to return to the position.

When the surface of the disc-shaped main body 28a on which the cam portion 28c protrudes is brought into contact with the back surface of the cover plate 19, the rocking projection 28b is positioned above the rocking plate 24. The horizontal portion 27a is set so that it can reach a position where it can be engaged and disengaged from below.
Therefore, when the swing member 28 is rotated in the counterclockwise direction in FIG. 5, the swing projection 28b rotates in a state of being engaged with the upper horizontal portion 27a, and the swing plate 24 is moved from the inner bottom surface of the water tray 14 as required. When the swing projection 28b is lifted by the distance and the swing projection 28b comes off the upper horizontal portion 27a, the swing plate 24 falls to the inner bottom surface of the water tray 14 by its own weight. That is, if the rocking motor RM is rotated during the ice making operation, the rocking plate 24 repeatedly swings up and down in the ice making chamber 16 around the pin 26 so that the ice making water can be constantly moved. Has become.

As shown in FIGS. 1 and 4, a lower end of a flat mounting jig 30 is pivotally supported by a shaft pin 29 projecting from the front surface of the set member 20 so as to be swingable.

Further, a tension spring 32 as elastic means is stretched between an upper corner portion of the mounting jig 30 on the pivot portion side and a holding piece 31 protruding from the set member 20, and the mounting jig 30 is provided with a tension spring 32. Shaft pin 29 under the elastic action of
Is always urged to swing clockwise with. That is, the tension spring 32 functions to hold the swing member 28 at an operating position where the swing projection 28b can be engaged with the upper horizontal portion 27a of the swing plate 24 during the ice making operation (see FIG. 5).
However, when a required external force is applied to the swing member 28,
The mounting jig 30 is allowed to swing counterclockwise by a required angle about the shaft pin 29 as a fulcrum.
(See FIG. 6).

An arc-shaped hole 30a is formed in the mounting jig 30 at a position separated from the pivot portion, and a regulating pin 33 protruding from the arc-hole 30a corresponding to the set member 20 is slidable. It has been inserted. The restriction pin 33 and the arc-shaped hole 30
“a” functions to regulate the swing range of the mounting jig 30. Under the elastic action of the tension spring 32, the operating position at which the regulating pin 33 contacts the lower end of the arc-shaped hole 30 a.

The setting member 20 includes a switch (detection means) SW for detecting completion of ice making, such as a microswitch.
The lever member 34 faces the downward locus of the cam portion 28c of the rocking member 28, and the rocking member 28
When the (mounting jig 30 and the swing motor RM) swing to the stop position, they come into contact with the cam portion 28c, and the switch SW
Can be switched. That is, when the ice making operation proceeds and the ice blocks 17 grow around the ice making projections 13, the rocking plate 24 comes into contact with the ice blocks 17 at the time of upward movement, and the upper horizontal portion 27a and the rocking projections 28b are moved. Thus, a downward reaction force is applied to the swing motor RM. For this reason, the mounting jig 3 on which the rocking motor RM is disposed
0 swings counterclockwise about the shaft pin 29 as a fulcrum, and the cam portion 28c presses the lever piece 34 of the switch SW during the swinging process, thereby changing the contact point of the switch SW from the "a" side. By switching to the “b” side, the completion of ice making can be detected. The actuator motor AM
Is started when the contact point of the switch SW is switched from the “a” side to the “b” side, and is controlled so as to start the rotation of the cam plate 21.

As shown in FIG. 8, the cam portion 28c of the swinging member 28 has a notch capable of switching the contact point of the switch SW to the "a" side when the swinging member 28 faces the stop position. A portion 28d is formed, and the swing motor RM is controlled to stop when the contact of the switch SW switches from the “a” side to the “b” side and then switches back to the “a” side.
The notch 28d of the cam 28c is
b is formed on the cam portion 28c so as to face a position corresponding to the lever piece 34 of the switch SW when facing the position separated from the upper horizontal portion 27a. It is configured so that control for separating from the tilt locus can be performed. That is, the motor RM is rotated even after the ice making completion detection switch SW is switched to the contact "b" side due to the tilting of the swing member 28,
When the notch 28d reaches the position corresponding to the lever piece 34 of the switch SW, when the contact of the switch SW is switched to the "a" side, the swing motor RM is set to stop. As a result, the swing projection 28b is attached to the swing plate 2
4 is separated from the tilt locus of the upper horizontal portion 27a, so that the tilting of the rocking plate 24 is not hindered.

On the back surface of the set member 20, a holding plate 36 is pivotally supported via a pivot shaft 35 at a position facing the upper side of the cam portion 28c of the swing member 28 so as to freely swing. The plate 36 is always configured to be able to swing integrally with the swing member 28 by abutting on the cam portion 28c. An arcuate engaging side 36a is formed at the open end of the presser plate 36, and the second protrusion 23 protruding from the cam plate 21 can be engaged with the engaging side 36a in a detachable manner from above. Is configured. The actuator motor AM started by detecting the completion of ice making by the ice making completion detection switch SW.
When the cam plate 21 is rotated by this, the second projection 23 is engaged with the engagement side 36a of the holding plate 36, so that the holding plate 36 is urged (oscillated) in a direction in which it comes into contact with the cam portion 28c. . That is, the rocking member 28 facing the stop position is urged downward by the pressing plate 36, and the rocking member 28 is moved until the notch 28d of the rocking member 28 reaches a position corresponding to the lever piece 34 of the switch SW. 28 is held at the stop position. When the second projection 23 is separated from the engagement side 36a, the swing member 28 is configured to return to the operating position under the elastic action of the tension spring 32.

[0017]

Next, the operation of the ice making machine according to the embodiment will be described. During the ice-making operation, the water tray 14 is held in a horizontal position, a required amount of ice-making water is stored in an ice-making chamber 16, and the ice-making projections 13 protruding from the ice-making substrate 11 are immersed in the ice-making water. Shall be The swing member 28 faces the operating position under the elastic action of the tension spring 32, as shown in FIG.

When the ice making operation is started in this state, a refrigerant is supplied from the refrigerating system to the evaporating tube 12, and the cooling of the ice making projections 13 protruding from the ice making substrate 11 is started by the heat exchange action. Since the ice making projections 13 are immersed in ice making water as shown in FIG. 2, ice formation starts around the projections 13 and gradually grows to form an inverted dome-shaped ice block 17. During the ice making operation, the rocking motor R
M continues to rotate. Therefore, the swing projection 28b of the swing member 28 rotated by the motor RM engages with the upper horizontal portion 27a of the engagement piece 27, and lifts the swing plate 24 upward. The swing projection 28b is moved to the upper horizontal portion 27a.
When the rocking plate 24 is separated from the water tray 14 by its own weight,
It comes into contact with the inner bottom surface of the. As described above, the swing plate 24 repeatedly swings in the ice making water in the ice making chamber 16 during the ice making operation, whereby the ice making water is constantly moved. Since the ice making water is always kept in the dynamic state, the ice blocks 17 formed on the ice making projections 13 are prevented from becoming cloudy, and transparent and clear ice blocks 17 are obtained.

When the complete ice block 17 is formed in an inverted dome shape on the ice making projection 13, the rocking plate 24 comes into contact with the ice block 17 at the time of upward movement, and finally the upper horizontal portion 27a and the rocking plate. The swing motor R is provided via the moving projection 28b.
This gives M a downward reaction force. Accordingly, as shown in FIG. 6, the mounting jig 30 on which the rocking motor RM is disposed is
The rotation in the counterclockwise direction is started with the shaft pin 29 as a fulcrum, and the cam piece 28c of the swinging member 28 presses the lever piece 34 of the ice making completion detection switch SW to change its contact from "a" side to "b". Side, thereby detecting completion of ice making. Then, the rotation of the actuator motor AM is started, the cam plate 21 rotates counterclockwise, and the first projection 22 eccentrically protruding from the cam plate 21 engages with the long hole 18 of the water tray 14, The water tray 14 starts to tilt obliquely downward.

In the swing motor RM, the lever piece 34 of the ice making completion detection switch SW is connected to the cam portion 28 of the swing member 28.
Even if it is pressed by c and switched to the contact "b" side, the rotation is continued. Further, with the rotation of the cam plate 21 in the counterclockwise direction, the second protrusion 23 is moved to the engagement side 36 a
7, the pressing plate 36 is urged downward in a state of contact with the cam portion 28c of the swinging member 28 as shown in FIG. Thus, even if the swing projection 28b provided on the swing member 28 is separated from the upper horizontal portion 27a, the mounting jig 30 is swung in the direction away from the switch SW under the elastic action of the tension spring 32. Instead, the rotation of the swing motor RM is continued. When the notch 28d formed in the cam portion 28c reaches a position corresponding to the lever piece 34, the pressing of the lever piece 34 is released and the switch S
When the W contact is switched from the “b” side to the “a” side, the swing motor RM stops rotating (see FIG. 8). Accordingly, the swing projection 28b provided on the swing member 28 stops at a position separated from the tilt locus of the upper water portion 27a in the swing plate 24, and prevents the tilt of the swing plate 24 from being hindered. Is done.

When the second projection 23 of the cam plate 21 is disengaged from the engagement side 36a of the holding plate 36, the mounting jig 3
0 returns to the original operating position under the elastic action of the tension spring 32. That is, when the deicing operation is completed and the water tray 14 rises and returns toward the ice making position, there is no need to provide a complicated mechanism for returning the swing member 28 to the operating position, and the structure is simplified. Moreover, since the tension spring 32 for holding the swinging member 28 in the operating position is engaged with the set member 20 disposed on the housing 10, the tension spring 32 is pulled by the actuator motor AM that tilts the water tray 14. The elastic force of the spring 32 is not applied, and there is no risk of failure or breakage.

[0022]

As described above, according to the ice making machine of the present invention, the ice making projection is immersed in the ice making water stored in the water tray to form an ice block around the ice making projection. In the above, during the ice making operation, the ice making water can always be positively moved by the rocking operation of the rocking plate. Therefore, the obtained ice block does not become cloudy, and has an advantage that a transparent and clear ice block having a high commercial value can be produced. Further, when the required ice block is formed on the ice making projection and the ice making is completed, the engaging member of the swinging means engaging with the engaging portion of the swing plate is separated from the tilt locus of the engaging portion. Since it moves to the position and stops, it is possible to prevent a situation where the tilting of the rocking plate that tilts with the water tray is hindered. In addition, since the holding plate is held at the stop position by contacting the rocking means with the operating portion provided on the cam plate for tilting the water tray, the tilt control mechanism of the rocking means can be extremely simplified. it can. That is, it is not necessary to control the elastic force of the elastic means with respect to the swing means when the swing means faces the operating position and when the swing means faces the stop position. In addition, when the water tray is returned to the ice making position, the elastic force of the elastic means is not applied to the tilting mechanism, so that the occurrence of failure of the mechanism can be suppressed.
