Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention provides a small door for taking out ice pieces from the ice storage container within the door of the freezer compartment opposite to the ice storage container installed in the freezer compartment, and this small door. This invention relates to a refrigerator in which an inner plate is provided with a hook that engages with the hook of the ice storage container and allows the ice storage container to be taken in and out when the small door is opened and closed.

[Background of the invention]

A conventional refrigerator with a small door for taking out ice pieces will be explained with reference to FIGS. 1 and 2. Reference numeral 1 denotes a refrigerator body, which has a freezer compartment 2 and a refrigerator compartment 3 inside. 4 is a freezer compartment door that closes the front opening of the freezer compartment 2. Reference numeral 5 denotes a conventionally known automatic ice maker installed in the freezer compartment 2. Reference numeral 6 denotes an ice storage container installed at the bottom of the automatic ice maker 5, which can be pulled out toward the front by being suspended from left and right rails (not shown) provided on the frame that constitutes the automatic ice maker 5. being done. Reference numeral 7 denotes a small door for taking out ice pieces, which is provided on the freezer compartment door 4 facing the ice storage container 6. A hook 8, a push plate 9 for causing the hook 8 to rotate, and a coil spring 10 are attached to the small door inner plate 7a. The push plate 9 and coil spring 10 are not engaged with the hook 8 when the small door 7 is closed, but when the small door 7 is opened, the push plate 9 is pushed down by the force of the coil spring 10, and the rib 8a of the hook 8 is pushed down. The hook 8 rotates in the direction of arrow A, that is, the direction of the ice storage container 6, and engages with the hook 6a of the ice storage container 6, so that the ice storage container 6 is pulled out in line with the opening of the small door 7. This is what I did.
The rotating position of the hook 8 is regulated by the rib 7b of the small door 7, so that the pushing plate 9 can be pushed down to an optimal position so that the hook 8 can be optimally engaged with the ice storage container 6.

In the ice chip removal small door 7 having the above structure, when the small door 7 is suddenly opened due to the customer's open state, for example, the hooking pawl 8 will further rise from the rotational position given by the push plate 9. , the hooking claw 8 vibrates due to the reaction, and the hooking claw 8 moves in the direction of arrow B.
When rotating in the direction opposite to the ice storage container 6, when the hooking claw 8 reaches the engagement position with the ice storage container 6, the hook 8 cannot engage with the hook 6a of the ice storage container 6, and the ice storage container 6 cannot be pulled out. However, there was a serious drawback in that only the small door 7 could be opened.

[Purpose of the invention]

The present invention aims to improve the above defects.

[Summary of the invention]

That is, by regulating the rotation stop position of the hooking claw by bringing the hook into contact with the regulating surface of the inner plate of the small door for taking out ice pieces, the hooking claw can be prevented from popping up. This ensures that the rotation stop position of the hooking pawl remains constant in any open state of the small door, ensuring smooth operation of the mechanism.

[Embodiments of the invention]

The present invention will be explained below with reference to an embodiment shown in FIG. 3 and FIGS. 4 and 5. Components with the same reference numerals as those in the conventional example indicate the same components.

11 is a push plate with a square hole 11a in the center, into which a small door rib 7b is inserted, and a coil spring 10 is press-fitted between the bottom surface of the square hole 11a and the lower surface of the rib 7b. Furthermore, a recess 11b is provided in the upper part of the push plate 11. There is a rib 8a in the center of the hook 8.
There are fitting claws 8b on the left and right sides. In addition, hook 8
As shown in FIG. 5, there are two fitting claws 8b. This fitting claw 8b is connected to the push plate 11 shown in FIG.
It is rotatably fitted to the rotation fulcrum E of. However, since FIG. 4 shows a cut along the hatched area, one of the two rotation axis points E is not shown. The hook 8 is attached to be rotatable about this rotation axis E, and 7c is a regulating surface that restricts the rotation.

That is, when the small door 7 is opened, the push plate 11 is pushed down by the force of the coil spring 10, and the flange at the upper end of the push plate 11 and the rib 8a are engaged as shown at point D in FIG. The ice storage container rotates in 6 directions,
It comes into contact with the regulating surface 7c and stops rotating. but,
At this time, there is a gap X between the upper side surface of the square hole 11a and the upper surface of the rib 7b, and the depressing force of the coil spring 10 is applied to the hooking claw 8, so that the hooking claw 8 when in contact is Prevent vibration.

In the above structure, the hook 8 when the small door 7 is opened is
It rotates in the direction of arrow A, that is, in the direction of the ice storage container 6, by the push plate 11, comes into contact with the regulating surface 7c, and stops rotating, and the push-down force of the push plate 11 regulates the reaction of the hook, keeping its rotating position constant. By keeping the ice storage container 6 at a certain temperature, the ice storage container 6 can be reliably linked with the ice storage container 6 and pulled out. Furthermore, the distance l1 between the rib 8a of the hook 8 and the locking point D of the push plate 11 and the rotation axis E of the hook 8, the contact point H between the hook 8 and the regulating surface 7c of the small door 7, and the The distance l2 between the hanging claw 8 and the rotation axis E is l2＞
By setting l1, the reaction when the hooking claw 8 comes into contact with the regulating surface 7c can be reduced, and
By arranging the cushioning material 12 on the regulating surface 7c, the reaction of the hooking claw 8 can be further reduced, and the sound upon contact can be further reduced.

〔Effect of the invention〕

The present invention prevents the hook from springing up and vibrating by regulating the rotation stop position of the hook by bringing the hook into contact with the regulating surface of the small door for taking out ice chips. By ensuring a constant rotation stop position, smooth operation of the mechanism can be guaranteed.

According to this embodiment, the cushioning material is pasted on the regulating surface, and the distance l1 between the locking point of the coil spring and the hooking claw and the rotation axis of the hooking claw and the rotation axis of the regulating surface and the hooking claw are By making the distance l2 larger than l1, the force with which the hooking claw contacts the regulating surface is made smaller than the rotational force of the coil spring, thereby buffering the impact when the hooking claw makes contact, By eliminating vibrations caused by impact, the effect of the hook rotation stop position regulating structure is further increased.
