[0002]

2. Description of the Related Art For example, in an automatic ice making device provided in an ice making chamber of a refrigerator, water is supplied to an ice tray by a water supply mechanism, and a temperature sensor attached to the ice tray has a predetermined temperature (for example, -19 ° C.).
When the completion of ice making is detected based on the detection of the ice making, the operation of turning the ice making tray upside down by the drive mechanism to drop the ice of the ice making tray into the ice storage container and reversing the ice making tray to return it to the original position. , Is configured to repeat automatically.

As a mounting structure of the temperature sensor in such an ice tray, the present applicant has previously applied for a structure as shown in FIG. 10 (Japanese Patent Application No. 1-37572). That is, the ice tray main body 1 is formed in a rectangular container shape having a plurality of ice making blocks 1a, and further two tongue-shaped engaging portions 2 are formed on the bottom surface thereof. The temperature sensor (not shown) has a shape that is located between the engaging portions 2 and 2 and that fits into the valley formed by the ice making block 1a, and the heat insulating cover 3 made of styrofoam or the like is attached to the lower portion thereof. The bottom surface of the ice tray body 1 is obtained by inserting both ends of the spring 4 having a substantially Z-shape for pressing the heat insulating cover 3 upward into the holes of the engaging portions 2 and 2 from the inside to engage the spring 4. It is attached to.

[0004]

By the way, in the ice removing operation of dropping the ice of the ice tray into the ice storage container, the ice tray body 1 is rotated to turn it upside down, and at the end of the rotation, the ice tray body 1 is rotated. By controlling the rotation of the one end side, the ice tray is twisted. However, in the above-described conventional configuration, when the ice tray body 1 is twisted, the locking portions 2 and 2 may be deformed in a direction in which they open to each other, that is, outward. At this time, if the end of the spring 4 is not inserted into the locking portions 2 and 2 sufficiently, the spring 4 may come off from the locking portions 2 and 2 and by extension, the ice tray body 1. ,
The heat insulating cover 3 and the temperature sensor will also come off the ice tray body 1.

The present invention has been made in view of the above circumstances, and an object thereof is to stably hold a temperature sensor for detecting the temperature of the ice tray body even against a twist of the ice tray body during the ice removing operation. The purpose is to provide an ice tray for an automatic ice making device.

[0006]

SUMMARY OF THE INVENTION An ice tray for an automatic ice making apparatus according to the present invention comprises an ice tray body having a plurality of downwardly projecting ice making blocks, and the ice tray on the bottom surface of the ice tray body. A temperature sensor arranged in a valley between the blocks, a heat insulating cover for covering the temperature sensor from the lower side, and a bottom portion of the ice tray body located on both sides of the ice tray body so as to sandwich the rotation axis of the ice tray body. And a fixing member made of a spring wire material that holds the temperature sensor with respect to the ice tray body by locking the mounting ends at both ends to the locking portions. In addition to the above, the fixing end portions of the fixing member are characterized in that they are configured to be locked to the locking portions from the outside (the invention of claim 1).

In this case, the fixing member is provided with a main portion located inside the pair of locking portions, and a pair of wraparound portions extending in opposite directions from both ends of the main portion and wrapping around the outside of the locking portion. And a pair of mounting end portions that extend inward from the end portions of these turn-in portions and are locked to the respective locking portions, and the overall widthwise dimension is the turn-in portion. It is effective if the width is equal to or larger than the dimension between the end portions of the above (claim 2). Further, at this time, a portion of the fixing member that extends from the turning portion to the mounting end portion may be folded back to form an acute angle (the invention of claim 3).

Further, a protrusion for restricting the outward movement of the fixing member can be provided on the bottom surface of the heat insulating cover (the invention of claim 4), and further, the fixing member can be provided on the bottom surface of the heat insulating cover. The rib may be provided near the mounting end of the above (invention of claim 5).

[0009]

According to the ice tray for an automatic ice making apparatus of the present invention, the temperature sensor is covered from below by the heat insulating cover, and the fixing member made of the spring wire is the engaging portion of the ice tray body. It is attached by being locked to. At this time, the temperature sensor is covered with a heat insulating cover from below,
Since the spring force of the fixing member holds the ice tray body in a pressed state, the temperature of the ice tray body can be reliably detected without being affected by the ambient temperature around the ice tray body. Moreover, since the temperature sensor is located in the valley between the ice making blocks, it is fixed without moving.

Further, since the fixing member made of the spring wire is used for attaching the temperature sensor and the heat insulating cover, it is possible to uniformly press the temperature sensor and the heat insulating cover over a wide range. Furthermore, since the fixing member made of the spring wire easily deforms by following the twisting deformation of the ice tray body even when the ice tray body is twisted, it is more stable than the case where it is fixed by screwing. The temperature sensor and the heat insulating cover can be held, and an excessive force is not applied to the locking portion.

Thus, when the ice tray body is twisted, a pair of locking portions provided on both sides so as to sandwich the rotation axis are displaced in the mutually opening direction, that is, outward. I have something to do. However, since the mounting ends at both ends of the fixing member are locked from the outside with respect to the locking part, even if the locking part is displaced outward due to a twist, the displacement direction Is in a direction to be locked deeper with respect to the mounting end portion of the fixing member, so that the fixing member can be prevented from coming off the locking portion.

Further, in this case, the fixing member is composed of a main portion, a pair of turning portions, and a pair of mounting end portions, and the overall width direction dimension is the width between the end portions of the turning portions. If it is configured so as to be equal to or larger than the directional dimension (the invention of claim 2), the temperature sensor and the heat insulating cover can be evenly pressed over a wider range. Further, when the portion of the fixing member that extends from the wrap-around portion to the mounting end portion is folded back to form an acute angle (invention of claim 3), when the mounting end portion is locked to the locking portion. The workability can be improved, and the mounting end can be made more difficult to disengage from the locking portion.

If a protrusion is provided on the bottom surface of the heat insulating cover for restricting the outward movement of the fixing member (invention of claim 4), the attaching end of the fixing member is formed by the protrusion. Can be effectively prevented from being disengaged from the locking portion, and further, a rib is provided on the bottom surface of the heat insulating cover in the vicinity of the mounting end portion of the fixing member (claim 5). Invention), it is possible to prevent human fingers from coming into contact with the mounting end of the fixing member made of the spring wire, and it is possible to improve safety.

As a result, the ice tray 20 is rotated by the drive mechanism and turned upside down. Also,
The frame body 21 is provided with a stopper portion 21a (see FIG. 5) so that the ice tray 20 is turned over (in the direction of arrow A in FIG. 5).
In addition, the rotation of the other end of the ice tray 20 is restricted to give a twist. Further, as shown in FIG. 6, an ice storage container 22 is arranged below the ice tray 20 so as to be able to move in and out. The machine body 18 is also provided with an ice storage amount detection lever 23 for detecting the ice storage amount of the ice storage container 22.

With the above configuration, the automatic ice making device 15 is
Water is supplied to the ice tray 20 through the water supply pipe 24 by the water supply mechanism 16, and when the ice making is completed, the ice tray 20 is inverted in the direction of arrow A to drop the ice into the ice storage container 22 (ice removing operation), and then the ice tray 20 is moved to the arrow. The operation of reversing in the direction opposite to A and returning to the original position is automatically repeated by the control device. Completion of ice making at this time is detected by a temperature sensor described later detecting a predetermined temperature (for example, -19 ° C). When the ice storage amount detection lever 23 detects that the inside of the ice storage container 22 is full of ice, the ice removing operation is prohibited and the ice making is interrupted.

Here, the ice tray 20 will be described with reference to FIGS. 1 to 4. The ice tray 20 includes a plastic ice tray body 25 and a temperature sensor 26 provided on the bottom surface thereof to detect the temperature of the ice tray body 25. Of these, the ice tray main body 25 is in the form of a rectangular thin container that extends in the front-rear direction as a whole, and a plurality of ice convex blocks 27 in this case are formed in a downward convex shape.
have. Then, as shown in FIGS. 1 and 2, through holes for locking a fixing member to be described later are provided inside the bottom surfaces of the four ice making blocks 27 located in the center of the ice making blocks 27. Tongue-shaped engaging portions 28 having 28a are formed respectively.

1 and 2 of the ice tray main body 25.
A connecting portion 25a connected to the output shaft 19 is formed at the center of the right end portion, and the frame body 2 is provided at the left end portion in FIGS.
A shaft portion 25b that is rotatably supported by 1 is provided. Therefore, the ice tray body 25 is adapted to rotate about the rotation axis C extending in the longitudinal direction at the center thereof. Further, the ice tray body 25 is provided with a locking piece portion 25c located at one end of the side portion on the shaft portion 25b side and locked by the stopper portion 21a of the frame body 21.

On the other hand, although not shown in detail, the temperature sensor 26 is constructed by arranging a temperature detecting element such as a thermistor in a long case having a trapezoidal cross section, and as shown in FIG. It is shaped so as to fit into the valley formed between the 27. The temperature sensor 26 is arranged in a valley portion between the ice making blocks 27 so that its longitudinal direction is substantially aligned with the rotation axis C, and the lower side is covered with a heat insulating cover 29, as described later, Both ends of the fixing member 30 are attached to the ice tray main body 25 by being engaged with the engaging portions 28, 28.

Now, the mounting structure of the temperature sensor 26 will be described in detail. As shown in FIG. 1 and the like, the heat insulating cover 29 is generally formed in a substantially “key” shape such that two vertical bars intersect with a horizontal bar extending in the left-right direction in FIG. It is designed to fit in the valley formed by Nono. Specifically, as shown in FIG. 4, this heat insulating cover 29 is configured by fitting an elastic heat insulating member 29b such as styrofoam into a thin plastic cover portion 29a. The (central portion of the horizontal bar) is adapted to the temperature sensor 26.

In this embodiment, a pair of rib-shaped protrusions 31, 31 are integrally provided on the bottom surface of the heat insulating cover 29 (cover portion 29a) as shown in FIGS. In addition, a pair of ribs 32, 32 are integrally provided. Of these, the protrusions 31 and 31 are symmetrically provided in the upper right portion and the lower left portion (symmetrical end portions of the two vertical bar portions) of the heat insulating cover 29 in FIG. 1, and are fixed members as described later. The movement of 30 in the outward direction is restricted. At this time, as shown in FIG. 4, inclined portions 31a and 31a are provided on the outer side portions of the protrusions 31 and 31, respectively. Further, the ribs 32, 32 are provided symmetrically at the center of the horizontal bar portion of the heat insulating cover 29, also in the upper right and lower left in FIG. 1, as will be described later.
It is located near the mounting end of the fixing member 30.

The fixing member 30 is made of, for example, a spring wire made of stainless steel, and is located inside a pair of facing locking portions 28, 28 as shown in FIGS. A main portion 30a extending in a diagonal direction so as to intersect the rotation axis C at the central portion, and Z-shaped portions extending in opposite directions from both ends of the main portion 30a and further bent toward the center side. A pair of turn-in portions 30b, 30b that go around the stop 28 and the turn-in portion 30
b, 30b extending inward from the ends of the locking portions 28, 2
8 has a pair of mounting ends 30c, 30c.

Further, at this time, as shown in FIG. 3, the widthwise dimension a of the entire fixing member 30 is determined as follows.
It is configured to be equal to or larger than the widthwise dimension b between the ends of b and 30b. The length c of the entire fixing member 30 in the direction of the rotation axis C corresponds to the two vertical bars of the heat insulating cover 29, and is larger than the width a of the whole fixing member 30.

When attaching the temperature sensor 26 to the ice tray body 25, as shown in FIG.
In the state where 6 is covered with a heat insulating cover 29 from the lower side (the upper side in FIG. 2), the ice making block 2
The bottom surface of the ice tray body 25 is fitted so as to fit into the valley portion between the seven. At this time, the heat insulating cover 29 is set to have a thickness such that its bottom surface is located below the through hole 28 a of the locking portion 28.

Then, in this state, while pressing the heat insulating cover 29 upward, the through holes 28a, 28a of the pair of locking portions 28, 28 facing the mounting end portions 30c, 30c of the fixing member 30, respectively. It is inserted from the outside,
In this work, one mounting end 30c is connected to one locking portion 28
After inserting the fixing member 30 into the through hole 28a from the outside,
This is performed by inserting the other mounting end portion 30c into the through hole 28a of the other locking portion 28 from the outside while elastically deforming the turning portion 30b so as to expand to the outside. At this time, when the other mounting end portion 30c is locked to the locking portion 28, the protruding portion 31 becomes an obstacle, but since the inclined portion 31a is formed on the outer side portion of the protruding portion 31, the fixing member 30 is formed. Can be smoothly crossed over the protrusion 31, and the mounting workability can be improved.

As a result, the main portion 30a and the turn-in portion 30b of the fixing member 30 are pressed against the bottom surface of the heat insulating cover 29 (cover portion 29a), and the heat insulating cover 29 (heat insulating member 29b) is compressed and deformed by its spring force. As a result, the temperature sensor 26 is held by being pressed against the ice tray body 25. The lead wire 26a (see FIG. 2) of the temperature sensor 26 extends in the direction of the rotation axis C at the bottom of the ice tray body 25 and is connected to the machine body 18.

At this time, as shown in FIG. 1, a pair of protrusions 31, 31 provided on the heat insulating cover 29.
Are positioned outside the turn-in portions 30b, 30b of the fixing member 30 to regulate their positions, and the pair of ribs 32, 3 are provided.
2, fixed end portions 30c and 30c of the fixing member 30 respectively
The tips of the are positioned so as to be close to each other.
Further, the main portion 30a of the fixing member 30 includes the pair of ribs 3
It extends so as to obliquely pass through the portion between 2 and 32, which makes it impossible to attach the fixing member 30 in an inverted state.

In the above structure, the temperature sensor 26 is
In the state of being covered by the heat insulating cover 29 from the lower side, the spring force of the fixing member 30 presses the ice tray main body 25 so that it is held, so that the ambient temperature around the ice tray main body 25 is not affected. The temperature of the ice tray body 25 can be reliably detected. Moreover, the temperature sensor 26
Since it is located in the valley between the ice making blocks 27, it is fixed without shifting. Since the temperature sensor 26 and the heat insulating cover 29 are fitted in the valleys of the ice making block 27, the temperature sensor 26 and the heat insulating cover 29 can be compactly arranged and the ice tray 20 as a whole does not become large in the height direction.

The temperature sensor 26 and the heat insulating cover 29 are also provided.
Since the fixing member 30 made of a substantially Z-shaped spring wire is used for mounting, the temperature sensor 26 and the heat insulating cover 29 can be evenly pressed over a wide range. Particularly, in this embodiment, the fixing member is provided. Since the overall widthwise dimension a of 30 is equal to or greater than the widthwise dimension b between the ends of the wraparound portions 30b and 30b, the temperature sensor 26 and the heat insulating cover 29 can be stably provided over a wider range. You can hold it down.

Further, the fixing member 30 made of the spring wire is
Even when a twist is applied to the ice tray body 25 during the ice removing operation, the ice tray body 25 is easily deformed following the twist deformation, so that the temperature sensor 26 and the heat insulation can be stably provided as compared with the case where the ice tray body 25 is fixed by screwing or the like. The cover 29 can be held, and an excessive force is not applied to the locking portion 28. Moreover, when the ice tray body 25 is twisted, the twisting force mainly acts in the direction orthogonal to the rotation axis C direction, that is, in the width direction of the fixing member 30, but the length dimension c of the fixing member 30 in the rotation axis C direction is determined. Since it is configured to be larger than the dimension a in the width direction, the amount of deformation of the fixing member 30 can be reduced, the stability is excellent, and the force acting on the locking portion 28 can be minimized. You can do it.

Thus, when the ice tray body 25 is twisted, the pair of locking portions 28, 28 provided on both sides so as to sandwich the rotation axis C are mutually attached. It will be displaced in the opening direction, that is, outward. However, since the mounting members 30c and 30c at both ends of the fixing member 30 are locked from the outside with respect to the locking portions 28 and 28, respectively, the locking portions 28 and 28 are accompanied by a twist. Even if the outer end is displaced, the displacement direction of the mounting end 3 of the fixing member 30
The fixing member 30 does not disengage from the locking portion 28 because the locking direction is deeper than 0c and 30c.

Further, as a result, the fixing member 30 is temporarily operated.
However, even if the mounting end portion 30c is mounted in a state where the mounting end portion 30c is not sufficiently inserted into the locking portion 28, the ice tray body 25
With the twist, the mounting end portion 30c can be expected to be inserted into the locking portion 28 to complete the mounting state.

Further, in this embodiment, the heat insulating cover 29 is used.
Further, by providing the protrusions 31 and 31 for restricting the outward movement of the fixing member 30, the effect of preventing the fixing member 30 from coming off is further enhanced. Further, by providing the ribs 32, 32 on the heat insulating cover 29, the ribs 32 serve as walls that prevent human fingers from hitting the attachment end portions 30c of the fixing member 30, and the ribs 32, 32 are attached to the end portions of the fixing member 30. Even if there is a flash, the safety can be improved.

Thus, according to this embodiment, the fixing member 3
Since the mounting end portions 30c at both ends of 0 are locked to the locking portion 28 from the outside, the spring 4 may be disengaged from the locking portion 2 when the ice tray body 1 is twisted. Unlike the conventional one in which the fixing member 30 has the locking portion 2
8 can be reliably prevented from coming off, and as a result, an excellent effect is obtained in that the temperature sensor 26 can be stably held even against the twist of the ice tray body 25 during the ice removing operation. Is something that can be done.

FIG. 7 shows a fixing member 41 according to another embodiment of the present invention. This fixing member 41 is also made of a spring wire rod, and has a main portion 41a and turn-in portions 41b, 41.
b, the mounting end portions 41c, 41c are formed in a substantially Z-shape.
The angle α with c is set to an acute angle slightly smaller than 90 degrees. At this time, the extending direction of the mounting end portion 41c is inclined by the angle β with respect to the line B orthogonal to the rotation axis C.

In this case, when mounting the fixing member 41, one mounting end portion 41c is inserted into the through hole 28a of the one locking portion 28 from the outside to expand the fixing member 41 and the turning portion 41b to the outside. When elastically deformed in this manner, the other mounting end portion 41c comes to face straight (direction of line B) with respect to the through hole 28a of the other locking portion 28, and the through hole 28a.
It is easy to insert into, and the workability of mounting can be improved. In addition, it is possible to expect an effect that the mounting end portion 41c is more unlikely to come off from the locking portion 28.

In each of the above embodiments, the fixing members 30, 4
1 has a substantially Z-shape, the fixing member 42 shown in FIG.
It is also possible to form an angular substantially S-shape like the above, or a curved substantially S-shape like the fixing member 43 shown in FIG. 9, and in short, it is possible to hold down the temperature sensor and the heat insulating cover. With various configurations, various modifications are possible. Further, the protrusions 31 and the ribs 32 may be provided as needed, and their shapes can be variously modified.

In addition, the present invention is not limited to the above-described embodiments, and various modifications are conceivable, for example, in the shape, structure, material, etc. of the heat insulating cover. The present invention can be applied to various automatic ice-making devices such as a device dedicated to ice-making, and can be appropriately modified and implemented without departing from the scope of the invention.

[0040]

As is apparent from the above description, the present invention has the following excellent effects.
That is, according to the ice tray for the automatic ice making device of the first aspect, since the mounting end portions of the fixing member are configured to be locked to the respective locking portions from the outside, the ice tray body is twisted. At this time, even if there is a circumstance in which the pair of locking portions are displaced in the direction in which they open to each other, it is possible to prevent the fixing member from coming off the locking portions, and to use a temperature sensor for detecting the temperature of the ice tray body. Even when the ice tray body is twisted during the ice removing operation, it can be stably held.

Further, in this case, the fixing member is composed of a main portion, a pair of turning-in portions, and a pair of mounting end portions, and the overall width dimension is the width between the end portions of the turning-in portion. If it is configured so as to be equal to or larger than the directional dimension (the invention of claim 2), the temperature sensor and the heat insulating cover can be evenly pressed over a wider range. Further, when the portion of the fixing member that extends from the wrap-around portion to the mounting end portion is folded back to form an acute angle (invention of claim 3), when the mounting end portion is locked to the locking portion. The workability can be improved, and the mounting end can be made more difficult to disengage from the locking portion.

If a protrusion for restricting the outward movement of the fixing member is provided on the bottom surface of the heat insulating cover (invention of claim 4), the attaching end of the fixing member is formed by the protrusion. Can be effectively prevented from being disengaged from the locking portion, and further, a rib is provided on the bottom surface of the heat insulating cover in the vicinity of the mounting end portion of the fixing member (claim 5). According to the invention, it is possible to prevent human fingers from coming into contact with the mounting end of the fixing member made of a spring wire, and to improve safety.
