引掛は爪には中央[Field of Application of the Invention] The present invention provides a small door for taking out ice pieces of the water storage container in the freezer compartment door opposite to the water storage container installed in the freezer compartment, and a small door for taking out ice pieces of the water storage container on the inner plate of the small door. The hook engages with the part, and the hook for inserting and removing the water storage container when opening and closing the small door is related to a refrigerator having a claw. (Background of the invention) Conventional small door for taking out ice pieces A] A refrigerator will be explained with reference to Figs. Freezer compartment 20) This is a freezer compartment door that closes the front opening. Reference numeral 5 designates a conventionally known automatic ice maker installed in the freezer compartment 2. 6 is automatic ice maker 5
It is a water storage container installed at the bottom of the automatic ice maker 5, and 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. 7 is a freezer compartment door 4 facing the ice storage container 6
This is a small door for taking out ice chips. 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 claw 8 when the small Ti 17 is closed, but when the small Ti 17 is opened, the push plate 9 and the coil spring 10 are pressed, and the plate 9 is pushed away by the force of the coil spring 10, so that the hook is not engaged with the claw 8. The hook 8 is engaged with the rib 8d, and the hook 8 is rotated from the direction of the arrow to the direction 11'i of the ice container book 6, and the hook of the water storage container 6 is engaged with the part 6a, and the small part 7 is opened. It is designed to pull out the ice container.
The push-F bending position of the pusher 9 is regulated by a rib 7b with a diameter of 7 so that the engagement state with the pusher 9 is optimal. -1, Kizozo's ice J- put it on the small door 7 for taking out) - Mt
For example, when the small door 7 is opened due to the open state of the small door 7 of the customer i, the hook 8 is moved further above the rotation position given by the push plate 9 (d), and due to the reaction. The hook 8 vibrates and becomes loose, and when the hook 8 reaches the engagement position with the ice storage container 6 when it is rotating in the direction of arrow 13, that is, in the opposite direction of the water storage container 6, the hook 8 becomes tr+. The hook of the ice storage container 6 cannot be engaged with the portion 6a, and there is a serious drawback that only the small door 7 can be opened without being able to pull out the ice container 6. [Summary of the Invention] That is, the rotation stop position of the hook is regulated by bringing the hook into contact with the regulating surface of the inner plate of the small door for taking out ice chips. This prevents the hook from flipping out and getting stuck, ensuring a constant rotation stop position of the hook no matter what state the small door is in, and guaranteeing the mechanism's long-lasting movement. [Embodiment of the Invention] The present invention will be explained below with reference to an embodiment shown in Fig. 3 and Figs. 4 and 5. The same reference numerals as in the conventional example indicate the same thing. 11 is a push plate with a square hole 11a in the center, into which the small door rib 7b is inserted, and a coil spring 10 is press-fitted between the bottom surface of the square hole 11 and the surface of the rib 71). In addition, there is a recess 1 on the top of the pusher 11. lb is provided. The hook of 8 is in the center of the claw.

There is. In addition, the small door inner plate 7 a j:
It fits into the rotation fulcrum E of and hooks :) The claw 8 is this time! I
+ Rotatable around fulcrum No. 1 f・t *jl''
+Jt, and 7 (: is a regulating surface that regulates its rotation. That is, when the small door 7 is opened, the force of the spring 10 pushes the push plate 11.
Press 1: gill A, recess 11. l) and the rib 8a are engaged, the hook 8 rotates in the direction of the water storage container 6, and stops rotating after hitting the regulating surface 7. There is a gap X h< between the two side surfaces of the rib 7b and the upper surface of the rib 7b, and the hook 8 has a coil spring 1.
The pushing force r = 0 is set at IIj, and prevents the motive force of the pulling claw 8 at the time of contact. In the L structure, r? The small door 7 opens 115 and the hook 8 is
The push plate 11 rotates in the direction of the arrow, that is, the direction of the ice container 6, and comes into contact with the regulating surface 7 (:) and stops rotating, and the push plate 11 is pushed down to prevent the hook from rebounding.
By keeping the rotating position constant, it is possible to reliably interlock with the water storage container 6 and draw out the water storage container 6. Furthermore, the hook is the distance Ql between the rib 8a of the claw 8 and the locking point of the push plate 11, and the rotation support 7t'-r= of the hook 8, and the distance Ql between the hook 8 and the restriction surface 7c of the small door 7. By setting the distance Eflood 2 between the contact point 1■ and the rotational fulcrum E of the hook I-zume 8 as Q, 2>D, l, the reaction when the Tagawa-kezume 8 comes into contact with the regulating surface 7c is can be made smaller, and a buffer '4''1 can be provided on the regulating surface 7c.
2, the hook can further reduce the reaction of the claw 8, and further reduce the sound when it makes contact. [Effects of the Invention] The present invention regulates the rotational stop position of the hook 4-J claw by bringing the hook into contact with the regulating surface of the small door for taking out ice pieces, thereby preventing the hook from coming off. - By eliminating vibrations and ensuring a constant rotation stop position of the hook, circular operation of the mechanism can be guaranteed. According to this embodiment, the cushioning material is attached to the regulating surface, and the coil spring and the hook are connected to the locking point of the claw and the rotation point of the hooking claw. By making the distance 1111Q2 from the fulcrum of the claw larger than al, the force with which the claw contacts the regulating surface is made smaller than the same force of the coil spring. 1. Slow down the impact. By eliminating vibration due to impact, the above-mentioned hook rotation stop 1-(l',': effect of the positioning structure ψ) is further improved. The middle theory is that the small door for taking out ice J1 is the conventional small door for taking out ice J1. Figure 2 is the small door for taking out ice J1.
