DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a refrigerator-freezer, and more particularly to a refrigerator-freezer incorporating an automatic ice making device.

[0002]

2. Description of the Related Art FIG. 6 is a perspective view showing a conventional automatic ice maker installed in a refrigerated freezer disclosed, for example, in Japanese Patent Application No. 2-128730, and FIG. FIG. 8 is a partially enlarged view of the perspective view.

In the figure, 13 is an automatic ice making device, 14 is an ice tray, 15 is an ice tray drive box which supports one end of the ice tray 14 and has a built-in drive mechanism for rotating it, 16 is the other end of the ice tray 14 Tray supporting plate for rotatably supporting the plate, 17
Is an ice storage box, 18 is a rod-shaped ice storage amount detection arm that traverses the upper part of the ice storage box 17 and swings inside thereof. One end is supported by the ice tray drive box 15, and the other end is an ice tray support plate 16. Is supported through. One end of the ice storage amount detection arm 18 supported by the ice tray support plate 16 has a right-angled bent portion 18.
With the tube 19 of a fixed size inserted between the a and the contracted portion 18b formed by cutting into a conical shape, the tube 19 is inserted into the hole 16a of the ice tray support plate 16, and the E-ring 20 is fitted into the contracted portion 18b. It is locked. Thus, the position of the ice storage amount detection arm 18 in the direction A is fixed by the right-angle bent portion 18a and the tube 19, and the position in the direction B is fixed by the contraction portion 18b and the E-ring 20.

Next, the operation will be described. The ice soul released by the torsional rotation of the ice tray 14 by the drive mechanism in the ice tray drive box 15 is dropped and stored in the ice storage box 17. At this time, the ice storage amount detection arm 18 is also driven by the drive mechanism in the ice tray drive box 15 and swings inside the ice storage box 17 as shown by an arrow C in FIGS. 15 and 17, and the ice storage amount in the ice storage box 17 is reduced. When the specified amount is reached, the ice storage amount detection arm 18 hits the ice storage and stops, so the drive mechanism in the ice tray drive box 15 detects this and stops its operation.

[0005]

The arm for detecting the amount of ice stored in the conventional automatic ice making device is constructed as described above.
If the ice connected to the ice tray is made due to variations in the amount of water supplied to the ice tray, the ice is caught on the arms at both ends of the ice storage detection arm located immediately below the ice tray, and the amount of ice stored in the ice storage box is regulated. It works even if the amount is not reached, and it does not detect it normally. Further, when ice is caught on the arm in a state where the ice storage amount is almost full, there is a problem that the ice soul that has been separated from the arm is rolled up in an ice tray.

[0006] The present invention has been made to solve the problems described above, the ice and ice removal to ice storage amount detecting arm is prevented引掛Ru, increases the strength of the ice storage amount detecting arm The purpose is to:

[0007]

In the refrigerator-freezer according to the present invention, the ice storage amount detection arm is provided with support portions extending inward in the horizontal direction from both support ends thereof, and from both of the support portions, toward the upper portion of the ice tray. A rising part which rises, a traversing part which folds the other ends of these rising parts and traverses the upper part of the ice tray in a direction perpendicular to the pivot axis, a hang part which folds the other end of these traversing parts and hangs down, and these hangs connecting the other end parts constituted by the ice storage amount detecting section which crosses a direction parallel to the oscillation axis of the ice box in the upper portion, a strong cross-sectional shape of the bent portion of the ice storage amount detecting arm
It is deformed to increase the degree .

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a side sectional view showing this embodiment, FIG. 2 is a partially enlarged side view of this embodiment, FIG. 3 is a partially enlarged front view of this embodiment, and FIG. FIG. 5 is a perspective view of the ice making device, and FIG. 5 is a partially enlarged perspective view of the ice storage amount detection arm in FIG.

In the figure, 1 is a refrigerator-freezer body, 3 is a freezing room, 5 is a refrigerator room, 6 is an upper partition, 7 is a lower partition,
8 is an ice creamer room, 9 is an ice creamer body, 11
Is a conductive member containing a regenerator, 12 is an ice cream container,
13 is an automatic ice making device, 14 is an ice tray, 15 is an ice tray drive box, 16 is an ice tray support plate, and 17 is an ice storage box.

Reference numeral 31 denotes a rod-shaped ice storage amount detection arm, 31a denotes one support portion which penetrates the hole 16a of the ice tray support plate 16 and is partially bent and extends inward in the horizontal direction.
The other support portions 31c, 3c supported by the ice tray drive box 15 and extending inward in the horizontal direction in the direction along the swing axis.
1d is a rising portion that rises from the support portions 31a and 31b toward the upper portion of the ice tray 14, 31e and 31f are bent at the other ends of the rising portions 31c and 31d so that the upper portion of the ice tray 14 is perpendicular to the swing axis. Crossing section, 31g, 31h
Is a hanging part that bends the other ends of these crossing parts 31e and 31f and hangs down. 31i connects the other ends of these hanging parts 31g and 31h and traverses the upper part in the ice storage box 17 in a direction parallel to the swing axis. Ice storage amount detectors 31j and 31k are rising portions 3
In the bent portion from 1c, 31d to the crossing portions 31e, 31f, the cross-sectional shape is deformed into a square different from the circular shape of the other portions to enhance the strength.

As described above, in this embodiment, both ends of the ice storage amount detecting portion 31i of the ice storage amount detecting arm 31 are supported by the ice tray supporting plate 16 and the supporting portions 31a, 3a to the ice tray driving box 15.
1b, it rises to the upper part of the ice tray 14 and hangs down across the upper part of the ice tray 14, and circumvents so as not to be directly under the ice tray 14. Even if the connected ice is released, the ice falls into the ice storage box without being caught by the ice storage amount detection arm 31, and the ice storage amount can be reliably detected. In addition, since the crossing portions 31e and 31f of the ice storage amount detection arm 31 are raised so as to cross the upper portion of the ice tray 14, this crossing portion is closer to the side of the ice making tray in the direction of the swing axis than the ice making tray. There is no need to provide a space for passing the detection arm crossing part on the side of the dish swinging axis, and the size of the automatic ice making device 13 in the ice tray swinging axis direction is shortened, thereby improving the effective use of the space.

Also, as in this embodiment, if the number of bent portions of the ice storage amount detection arm 31 is large and the overall length is long,
Although there is a fear of being deformed when a force is applied at the time of assembling or detecting ice, as shown in FIG. 12, the cross-sectional shape of the bent portions 31j and 31k is deformed from the circular shape of the cross-sectional shape of the other linear portion to form a square. Therefore, the strength is enhanced, and accurate detection is possible without deformation even when a force is applied during assembly or ice detection.

In the above embodiment, the bent portion 31
j, 31k was reinforced, but even if other bent parts were reinforced,
Even if all the bent portions are reinforced, the cross-sectional shape thereof is not limited to a square, but may be another shape.
