SOLUTION: A detection lever 21 is provided with a first abutment part 34 and a second abutment part 35. The first abutment part 34 abuts on ice when the ice is reserved above the specified level at the middle section in backward and forward direction of an ice reserving container 20, and stops the detection lever 21 above the full level, and the second abutment part 35 abut ice when it is reserved above specified level at the inner part in backward and forward direction of the ice reserving container 20, and stops the detection lever 21 above full level. Hereby, the detection lever 21 can be stopped in the position geared to the level of the ice also in the case that it is reserved, being biased to the inner part, needless to say in the case that the ice within the ice reserving container 20 is reserved to form a partial rise at the middle part in backward and forward direction.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic ice making apparatus for automatically performing an ice making operation from water supply to ice release.

[0002]

Conventionally, for example, in an automatic ice making device incorporated in an ice making room of a home refrigerator, after water is supplied to an ice making tray, the temperature of the ice making tray is lowered to the ice making completion temperature and the completion of ice making is detected. Then, a series of ice making operations of inverting the ice tray and releasing ice are automatically executed. Ice that has fallen from the ice tray due to ice separation is stored in a drawer-type ice storage container located below the ice tray, and the user can pull out the ice storage container to take out the ice.

[0003] In this case, if the next ice release operation is performed while the ice in the ice storage container is full, the ice overflows from the ice storage container. Therefore, a detection lever 1 as shown in FIG. It is configured to detect whether or not the ice i in the ice storage container 2 is full. That is, the detection lever 1 is provided on the body 3 so as to rotate up and down (in the directions of arrows A and B) around the shaft portion 4, and rises in the direction of arrow A when ice is released, and stores ice. After retreating from the container 2 and after the ice-releasing operation is completed, the container 2 is rotated downward in the direction of arrow B and descends, and comes into contact with the surface of the ice i in the ice storage container 2 and stops. A sensor (not shown) for detecting the height position of the detection lever 1 is provided in the body 3.
Is located above a predetermined full height, for example, the ice storage container 2
Until the detection lever 1 is displaced below the full height position after the ice i is taken out from the apparatus, the next ice separation operation is prohibited.

[0004] In a normal state, ice i falling from an ice tray (not shown) is, as shown in FIG.
It is designed to be stored in a gentle mountain shape that rises almost in the middle in the front-rear direction. Therefore, the contact part 1a at the tip of the detection lever 1 is located corresponding to the middle part of the ice storage container 2 in the front-rear direction, and as shown in FIG. It is set so that the height can be detected.

[0005] However, when the user moves the ice storage container 2 in and out, for example, by vigorously pulling out (in the direction of arrow C), as shown in FIG.
May be biased toward the back. When such a deviation occurs, the ice i remains at a predetermined position in the middle part of the ice storage container 2 in the front-rear direction, although the ice i has accumulated near the upper end of the ice storage container 2 in the deep part of the ice storage container 2. Since the water is not stored at a height higher than the height, the detection lever 1 does not detect the full state, and the next ice detaching operation is executed. Therefore, there is a possibility that the ice i may spill out from the ice storage container 2, particularly from the rear side wall.

In this case, if the full height of the detection lever 1 is previously set low, it is possible to prevent the ice i from spilling out of the ice storage container 2 as described above. As a result, the capacity of the ice storage container 2 cannot be used effectively. Note that, for example, the size of the ice storage container 2 and the positional relationship between the ice tray and the ice storage container 2 are different depending on the type of the refrigerator, so that the way of storing the ice i in the ice storage container 2 with respect to the machine body 3 is also different. For this reason, the length of the detection lever 1 and the position of the contact portion 1a need to be individually set based on the shape of the ice storage container 2, the positional relationship between the ice storage container 2 and the ice tray, and the like. There is also a situation where the detection lever 1 is required.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a configuration in which the amount of ice stored is detected in accordance with the height position of a detection lever, even if the ice stored in the ice storage container is biased. It is an object of the present invention to provide an automatic ice making device that can stop a detection lever at a position corresponding to the height of ice and can prevent ice from falling off.

[0008]

According to the present invention, an automatic ice making apparatus has a detection lever which stops from coming into contact with the ice stored in the ice storage container from above and an intermediate portion in the front-rear direction of the ice storage container. A first abutting portion and a second abutting portion corresponding to an innermost portion of the ice storage container in the front-rear direction, wherein the first abutment portion is provided with ice in the ice storage container at an intermediate portion in the front-rear direction. When stored at a predetermined height or higher, the detection lever is stopped at a position higher than the full height by contacting the ice and the second
When the ice in the ice storage container is stored at a predetermined height or more at the back in the front-rear direction, the abutment portion contacts the ice to stop the detection lever at a position higher than the full height. It has a characteristic in the place where it is set.

According to this configuration, in a normal state in which the ice in the ice storage container is stored so as to rise near the middle portion in the front-rear direction of the ice storage container, the first abutting portion of the detection lever is in the ice storage container. When the ice in the ice storage container is biased toward the back of the ice storage container, the second contact portion of the detection lever comes into contact with the ice in the ice storage container. When the ice in the ice storage container is stored at a predetermined height or more in either the front-rear middle portion or the back portion of the ice storage container, the detection lever is stopped at a position higher than the full height. Therefore, not only when the amount of ice storage has reached the maximum amount, but also when ice is skewed to the back of the ice storage container and the state where ice is easily dropped from the ice storage container is detected, Since ice can be stopped from being stored in the ice storage container any more, it is possible to prevent ice from overflowing from the ice storage container as much as possible.

In this case, if at least one of the first contact portion and the second contact portion is provided so as to be capable of changing its position in the front-rear direction with respect to the detection lever (the invention of claim 2), A contact portion can be provided at an appropriate position according to the length in the front-rear direction and the positional relationship between the ice storage container and the ice tray,
In addition, the components can be shared.

DESCRIPTION OF THE PREFERRED EMBODIMENTS A first embodiment (corresponding to claim 1) in which the present invention is applied to an automatic ice making device provided in a refrigerator will be described with reference to FIGS. FIG. 4 shows a portion related to the gist of the present invention in the longitudinal sectional structure of the refrigerator. In FIG. 4, an ice making chamber 12 is provided at the center of the refrigerator main body 11. Cooling air from a refrigeration cycle (not shown) is supplied into the ice making chamber 12, so that the internal temperature is maintained at, for example, -18 ° C. The front opening of the ice making chamber 12
The door 12a is opened and closed by a drawer-type door 12a.
Are connected. Further, the refrigerator main body 11 is provided with a refrigerator compartment 13 having a pivoting door 13a located above the ice making compartment 12, and a drawer door 14a located below the refrigerator compartment 13. A freezer compartment 14 is provided.

The automatic ice making device 15 according to the present embodiment is provided with an ice making device main body 16 provided on the ceiling of the ice making room 12 and a water supply device 17 provided in the refrigerator compartment 13. I have. The ice making device main body 16 is provided with an ice tray 18 on the rear side of the body 16a, and water from the water supply device 17 is supplied to the ice tray 18 via a water supply hose 17a by a fixed amount. Ice i (see FIGS. 2 and 3) is produced in the dish 18.

The ice tray 18 is made of an elastically deformable plastic material. When the ice making operation is completed by a mechanism to be described later, the ice tray 18 is rotated from a horizontal position to an inverted position and twisted at the final stage of the rotation. Ice movement is performed. A temperature sensor 19 for detecting the temperature of the ice tray 18 is attached to the back surface of the ice tray 18. Based on the temperature detected by the temperature sensor 19, it is possible to determine the ice making completion time or the presence or absence of water supply.

The ice i (see FIGS. 2 and 3) that has fallen from the ice tray 18 due to the ice releasing operation is stored in an ice storage container 20 disposed below the ice tray 18. The ice storage container 20 has a substantially rectangular container shape that is long in the front-rear direction, and is connected so that a front wall portion 20a extends along the back surface of the door 12a. In addition, the rear side wall portion 20b of the ice storage container 20 has a height approximately half that of the front side wall portion 20a. As a result, the ice storage container 20
a from the ice making chamber 12 in accordance with the opening / closing operation of the a.
b does not hit the ice making device main body 16 and the ice making tray 18.

On the side surface of the body 16a of the ice making device main body 16, a thin plate-like detection lever 21 for detecting the amount of ice stored in the ice storage container 20 is vertically moved with the shaft 21a as a fulcrum (in the directions of arrows A and B). ) Is rotatably mounted.
Details of the shape of the detection lever 21 will be described later.
The detection lever 21 is moved to the highest position in the vertical movement range when the ice tray 18 is rotated to the reversing position during the ice releasing operation by a mechanism described later, and the ice tray 18 is completed again when the ice releasing operation is completed. When the ice storage container 20 is returned to the horizontal position, the ice storage container 20 is lowered and comes into contact with the upper surface of the ice i in the ice storage container 20 from above to stop.
It is possible to detect whether or not the ice storage amount is sufficient.

A slit (not shown) is formed in the rear side wall portion 20b of the ice storage container 20, and the detection lever 21 passes through the slit when the ice storage container 20 is taken in and out. When the door 12a is pulled out, the ice making operation of the ice tray 18 is not performed.

Next, FIG. 5 shows the body 1 of the ice making device main body 16.
6a shows an internal structure. In the figure, a gear transmission mechanism 23 that rotates in response to the driving of a motor 22 is disposed in a rectangular box-shaped body 16a, and the last gear among the gears constituting the gear transmission mechanism 23 is provided. 24 has an output shaft 24a projecting from the back of the fuselage 16a.
The ice tray 18 is attached to the tray. Cam grooves 25 are formed on both end surfaces of the gear 24 (only the front side is shown), and the gear 24 moves as shown in FIG.
The motor 22 is configured to rotate in a clockwise direction and then rotate counterclockwise in response to the reverse rotation of the motor 22. Thus, at the time of the ice releasing operation, first, the ice making tray 18 rotates by the motor 22 being rotated forward to reach the reversal position to perform ice removal, and then the ice making tray 18 is rotated by the motor 22 being rotated in the reverse direction. It is to be returned to a horizontal position.

Here, a first operation arm 26 and a second operation arm 27 are rotatably supported in the body 16a, and these operation arms 26 and 27 are driven by the rotation of the gear 24. To rotate up and down. That is, the base end of the first operation arm 26 is rotatably supported by the shaft portion 26a, and the intermediate portion 26b enters the cam groove 25 formed on the end surface of the gear 24, and Has a magnet 28 attached.

When the intermediate portion 26b of the first operating arm 26 is guided by the cam groove 25 in accordance with the rotation of the gear 24, the magnet 28 reciprocates vertically. That is, when the gear 24 rotates clockwise, in other words, when the ice tray 18 starts to be inverted, the magnet 28 descends and rises when the inversion has been completed (when it is located at the inverted position). On the other hand, when the gear 24 rotates counterclockwise and the ice tray 18 starts to return, the magnet 28 descends and rises when the ice tray 18 returns to the horizontal position.

On the other hand, a dish position sensor 30 composed of, for example, a Hall IC is mounted at a position corresponding to the magnet 28 on a printed wiring board 29 arranged in the body 16a alongside the gear 24. The magnet 28
Is located closest to the tray position sensor 30 when the tray is ascended, and its proximity is detected.
8 is detected at the reversal position and the horizontal position. This allows the motor 22 to respond to the detection of the dish position sensor 30.
The normal rotation and the reverse rotation can be switched.

An intermediate portion of the second operation arm 27 is rotatably supported by a shaft portion 27a, and its base end portion 27b is connected to a cam groove (not shown) formed on an end surface of the gear 24. ing. The cam groove is formed so as to move the base end 27b of the second operation arm 27 downward according to the clockwise rotation of the gear 24 by a predetermined angle.
That is, while the ice making tray 18 is turned over to perform the ice releasing operation, the base end portion 27b of the second operation arm 27 is moved downward.

On the other hand, as described above, the base end of the detection lever 21 is supported by the shaft 21a penetrating the side wall of the body 16a so as to be vertically rotatable on the side surface of the body 16a. In the body 16a, the shaft portion 21a has a bifurcated third
The third operation arm 31 swings integrally with the vertical rotation of the detection lever 21. In this case, the tip of the second operation arm 27 is located below one side (not shown) of the third operation arm 31, and the second operation arm 27 is turned in accordance with the rotation of the gear 24. When the base end 27b of the second operating arm 27 moves downward, that is, when the ice tray 18 is turned over, the distal end of the second operating arm 27 moves upward with the movement, and the third operating arm 31 and thus the detection lever 21 move. To the upper position (retreat position) in the direction of arrow A. Further, with the return rotation of the gear 24 after the ice is released (the rotation of the ice tray 18 to the horizontal position), the detection lever 21 returns in the direction of arrow B, comes into contact with the upper surface of the ice i, and stops. .

Further, a magnet 32 is attached to the tip of the other side 31a of the third operation arm 31, and the magnet 32 is moved in the front-rear direction in FIG. It is made to rock. At this time, an ice storage amount detecting means, for example, an ice storage amount detection sensor 33 composed of a Hall IC is mounted on the printed wiring board 29 in accordance with the movement locus of the magnet 32. In this case, when the detection lever 21 passes through the full height which is a predetermined position slightly higher than the retracted position, which is the upper position of the vertical rotation range, the third storage arm is used. The magnet 32 on the other side 31b of the base 31 is closest to detect the proximity. In such an ice storage amount detection sensor 33,
Ice storage is detected as follows.

That is, the detection lever 21 in contact with the ice i in the ice storage container 20 is rotated by the rotation of the gear 24 so that the ice tray 18 is rotated.
Rises to the evacuation position due to the reversal of
As the third operation arm 31 rotates, the magnet 32 passes through the ice storage amount detection sensor 33, so that the first approach is detected. Then, when the detection lever 21 is lowered with the ice making operation being completed and the ice tray 18 being returned to the horizontal position, the third operation arm 31 is rotated back. At this time, when the detection lever 21 moves to a position lower than the full height, the magnet 32 of the third operation arm 31 approaches the ice storage amount detection sensor 33 again, and the second detection is performed.

On the other hand, when the detection lever 21 stops at a position higher than the full height and comes into contact with the ice i in the ice storage container 20, the magnet 3 is returned when the third operation arm 31 is rotated back.
2 stops before it reaches the ice storage amount detection sensor 33, so that the second detection is not performed.

As described above, if the ice storage amount detection sensor 33 continuously detects the approach of the magnet 32 twice during the ice releasing operation, it is determined that the ice storage amount has not reached the full state. Is not detected, it is detected that the ice storage amount is full.

Now, the shape of the detection lever 21 will be described with reference to FIGS. Detection lever 21
Extends rearward while tapering slightly from the base end side toward the distal end side. Then, the detection lever 21
The first contact portion 34 is provided integrally with the lower side portion so as to protrude downward from the base end portion 21a so as to be approximately one-third the length of the whole, and is positioned at the front end portion. The second abutment portion 35 is integrally provided so as to protrude downward.

The first abutting portion 34 is provided substantially at an intermediate portion of the ice storage container 20 in the front-rear direction, and as shown in FIG. Is stored at a predetermined height (height necessary to prevent the ice i from spilling out of the ice storage container 20) at an intermediate portion in the front-rear direction, and comes into contact with the surface of the ice i to detect the detection lever 21. Is stopped at a position higher than the full height.

On the other hand, the second contact portion 35 is
0, as shown in FIG. 3, the downward projecting length is such that the ice i has a predetermined height at the depth in the front-rear direction in the ice storage container 20 (the ice storage container 20 of the ice i). When it is stored at a height higher than that necessary to prevent the water from spilling, the detection lever 21 is brought into contact with the upper surface of the ice i to stop the detection lever 21 at a position higher than the full height.

The automatic ice making device 15 having the above configuration is driven and controlled by a control device (not shown) provided at an appropriate position of the refrigerator main body 11. The control device is mainly composed of a microcomputer, and includes a signal from a door switch (not shown), a temperature signal from the temperature sensor 19, a dish position signal from the dish position sensor 30, and a detection signal from the ice storage amount detection sensor 33. Is input, and based on these input signals, the water supply device 17 is supplied.
Of the water supply pump 17a and the motor 22 is controlled,
It is configured to automatically execute a series of ice making operations.

Next, the operation of the above configuration will be described with reference to FIGS. First, after water is supplied to the ice tray 18, when the ice i is produced, when the completion of the ice making operation is detected based on the temperature detected by the temperature sensor 19, the control device makes the ice storage container 20 full. The ice release operation is executed on condition that the door is not in the state and the door 12a is not opened. Thereby, the ice tray 18 rotates from the horizontal position to the inverted position, and the ice i falls into the ice storage container 20.

At this time, after the detection lever 21 once moves to the retracted position as described above, the detection lever 21 comes into contact with the upper surface of the dropped ice i and stops, so that the ice storage amount becomes full. No is detected.

When the ice storage amount of the ice storage container 20 is less than the full state, that is, when the stop height position of the detection lever 21 is lower than the full height, the ice making operation from the water supply to the ice tray 18 is repeated repeatedly. Be executed.

As the ice making operation is repeated in this manner, the amount of ice stored in the ice storage container 20 gradually increases, and finally becomes full. When the amount of ice stored in the ice storage container 20 becomes full, the stop height of the detection lever 21 becomes equal to or higher than the full height at the time of detection by the detection lever 21 as described above,
Thus, the full state is detected, and the next ice making operation (ice releasing operation) is prohibited. With this, ice storage container 2
In the area 0, a large amount of ice i is always stored without falling off from the ice storage container 20.

After the full state is detected, the presence or absence of the magnet 32 is constantly monitored by the ice storage amount detection sensor 33, and the ice lever i is taken out from the ice storage container 20, so that the detection lever 21 becomes full high. If it falls below that, it is detected and the ice making operation is restarted.

However, usually, the ice making tray 1
When the ice i falls from 8, the ice i is stored in a raised state in the middle part in the front-rear direction of the ice storage container 20, as shown in FIG. However, when the door 12a is pulled out, the ice i in the ice storage container 20 is moved by the pulling-out force, as shown in FIG.
As shown in FIG.

On the other hand, in the present embodiment, when the ice i in the ice storage container 20 is stored at a predetermined height or more in an intermediate portion in the front-rear direction of the ice storage container 20, as shown in FIG. The contact portion 34 contacts the ice i to stop the detection lever 21 at a position higher than the full height. On the other hand, when the ice i in the ice storage container 20 accumulates more than a predetermined height in a direction toward the back of the ice storage container 20 (see FIG. 3), the second contact portion 3
5 comes into contact with the ice i on the back side of the ice storage container 20 and the detection lever 2
1 is stopped at a position higher than the full height. Therefore, even if the ice i accumulates at a predetermined height or more, not only at the intermediate portion in the ice storage container 20, but also toward the back, the height can be detected.

As described above, according to this embodiment, the detection lever 21 is provided with the first contact portion 34 and the second contact portion 35,
If the ice i in the ice storage container 20 is stored at a predetermined height or higher in the middle part in the front-rear direction of the ice storage container 20, the first
When the contact portion 34 contacts the ice i to stop the detection lever 21 at a position higher than the full height, and the ice storage container 20 is stored at a predetermined height or more at the back in the front-rear direction,
The second contact portion 35 contacts the ice i and the detection lever 21
Is stopped at a position higher than the full height.

Therefore, in the normal state where the ice i in the ice storage container 20 is stored in a raised state in the middle part in the front-rear direction, it is assumed that the ice i is full when a sufficient amount of ice i is stored. Of course, even if the ice i in the ice storage container 20 is biased to the back,
When the next de-icing operation is performed by the contact portion 35, the ice i
Can be detected in a full state in which is dropped.

As a result, unlike the conventional ice storage device, the contact portion 1a of the detection lever 1 contacts the ice i only at the middle portion in the front-rear direction of the ice storage container 2 to detect whether or not the ice storage amount is full. Even if the ice i stored in the container 20 is unbalanced, the detection lever 21 can be stopped at a position corresponding to the height of the ice i, and the ice i can be reliably prevented from falling off. In this case, the ice storage container 2
The volume of 0 can be effectively used, and the maximum ice storage amount can be increased. Furthermore, since it is only necessary to change the shape of the detection lever 21, it is possible to obtain an advantage that it can be completed with a simple configuration.

Next, a second embodiment (corresponding to claim 2) of the present invention will be described with reference to FIGS. In the present embodiment, the configuration of the detection lever 41 is different from that of the first embodiment. That is, the detection lever 41 is
The first and second abutting portions 43 and 44 are attached to the lower side portion so as to be changeable in the front-rear direction. In this case, ribs 42a projecting from both sides are formed on the lower side of the detection lever main body 42, and fitting portions 43a and 44a having a U-shaped cross section are formed above the first and second contact portions 43 and 44. The first and second contact portions 43 and 44 are attached to the detection lever main body 42 by providing the fitting portions 43a and 44a with the ribs 42a. In this case, the fitting portions 43a and 44a
a with a predetermined frictional force, and can be moved in the front-rear direction by applying a force against the frictional force.

According to the above configuration, the first contact portion and the second contact portion
The height of the ice i in the ice storage container 20 is changed according to the length of the ice storage container 20 in the front-rear direction and the positional relationship between the ice tray 18 and the ice storage container 20 by appropriately changing the positions of the contact portions 43 and 44. Since the first contact portion and the second contact portions 43 and 44 can be provided at appropriate positions for detection, the components can be shared. In this case, only the first contact portion may be changeable in position, or only the second contact portion may change position.

The present invention is not limited to the embodiment described above and shown in the drawings, but can be modified or expanded as follows. When the control device confirms that the ice storage amount is full, the control device stops the rotation of the ice tray 18 to stop the ice releasing operation.
The operation of supplying water to 8 may be stopped. In short, it is sufficient to prevent further ice i from being stored in the ice storage container 20.

The ice storage amount detecting means is not limited to the Hall IC, but may be a mechanical switch such as a micro switch. In this case, when the detection lever is positioned below the full height, the tip of the other side of the third operating arm contacts the microswitch and is turned on, and when the detection lever is positioned at or above the full height, the third operation arm is turned on. By configuring so that the tip of the other side of the operation arm is separated from the microswitch and switched off, it is possible to detect whether or not the ice storage amount is full by switching the on / off state. The present invention can be applied not only to an automatic ice maker provided in a refrigerator but also to an automatic ice maker alone.

[0045]

As is apparent from the above description, according to the automatic ice making device of the present invention, the detection lever is provided with the first contact portion and the second contact portion, and the ice is stored in the ice storage container. When stored at a predetermined height or higher in the middle part in the front-rear direction, the first
When the detection lever stops at a position higher than the full height due to the contact portion of the ice contacting the ice, and the ice is stored in the ice storage container at a predetermined height at the back portion in the front-rear direction, the second contact portion. Since the detection lever is stopped at a position higher than the full height when the contact portion comes into contact with the ice, the ice in the ice storage container rises to the middle part in the front-rear direction and is stored as a matter of course. However, even when the ice is stored in the back, the detection lever can be stopped at a position corresponding to the height of the ice to detect that the ice is full, and as a result, the ice from the ice storage container can be detected. Spills can be prevented as much as possible.
