Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improved configuration of an ice maker, and particularly to provide a water storage amount detection device that can operate accurately without being affected by outside temperature.

An embodiment of the present invention will be described below based on the drawings.

1 is a heat insulating box body, 2 is a refrigeration system evaporation pipe 3 installed on the back side,
An ice-making plate 4 is installed at an angle in the upper part of the box body 1, and 4 is an ice-making plate 2.
A cutting heater installed in front of the lower edge of
is a water storage amount detection device of the present invention mounted on the upper side wall of the ice storage 5, which detects that a predetermined amount of ice has been stored in the water storage 5 and promptly stops the water storage operation.

Next, the configuration of the water storage amount detection device 6 will be described in detail.

A resin substrate 8 having a reed switch 7 for ice-making operation control attached to the lower back surface is fixed to the upper side wall of the water storage 5.

Further, a resin rotating plate 9 whose upper end is rotatably supported is provided on the upper part of the board 8, and the reed switch 7 is provided on the lower back surface of the resin rotating plate 9.
A permanent magnet 10 that opens and closes as appropriate is attached.

Lug pieces 12 having bearing openings 11 formed integrally with the substrate 8 are protruded from a pair of left and right sides of the upper portion of the substrate 8.

On the other hand, the rotating plate 9 and the shaft portion 13 are integrally molded on the left and right pair of the upper end of the rotating plate 9, and the shaft portion 13 is connected to the bearing opening 1, respectively.
1, the rotating plate 9 is supported in a rotational relationship with respect to the base plate 8.

In addition, the substrate 8 has a first plate coated with resin so that the slide can be adjusted.
A second magnetic body 15 corresponding to this magnetic body 14 in a repulsive relationship is attached to the rotating plate 9 side.

The second magnetic body 15 is insert-molded into the rotary plate 9.

The rotary plate 9 is normally held at an inclined position where the permanent magnet 10 does not operate the reed switch 7 due to the repulsive relationship between the first magnetic body 14 and the second magnetic body 15.

The surface of the rotating plate 9 on the side that the ice cube comes into contact with is coated with rubber 16.
covered with.

Next, the operation of the water storage amount detection device of the present invention constructed as above will be explained.

When the ice cubes in the water storage 5 increase and reach a predetermined amount, the rotating plate 9
is pushed backwards by the ice cube.

Then, the permanent magnet 10 attached to the lower part of the rotating plate 9 approaches the reed switch 7 and operates the switch 7.
The ice making operation is stopped by making the refrigerator 17 inoperative.

When the ice cubes in the ice storage 5 decrease again and move away from the rotating plate 9, the rotating plate 9 quickly returns to its normal state due to the repulsive force between the first magnetic body 14 and the second magnetic body 15. Since the permanent magnet 10 is also separated from the reed switch 7, the reed switch 7 works to restart the ice-making operation.

Note that in the above-described configuration, since the first magnetic body 14 can be slid and adjusted, the first magnetic body 14 and the second magnetic body 15
The position of the first magnetic body may vary if there are slight variations in various parts due to the variable repulsion force, if the repulsion force changes due to long-term use, or if it is used in various ice makers with different ice sizes. By adjusting the position of the rotating plate relative to the reed switch, it is possible to accurately set the position of the rotary plate relative to the reed switch.

Since the present invention is a water storage amount detection device configured as described above, it is extremely reliable because it does not malfunction due to the influence of outside temperature and can stop ice-making operation when the predetermined amount of water in the water storage storage is detected. This is an expensive ice maker.

In addition, the repulsive force between the first magnetic body and the second magnetic body allows the permanent magnet to hold the rotary plate in the normal tilted position where the reed switch is not operated. It also improves structural durability because it can last for a long time.

Furthermore, the return operation of the rotary plate when the ice-making operation is restarted is smoothly performed by the repulsive force between the first magnetic body and the second magnetic body, and the reed switch is extremely reliable in terms of its operation without chattering.

Furthermore, since the repulsive force of the present invention can be varied by adjusting the position of the first magnetic body, it is possible to prevent defective products from being produced during the assembly and use stages even if there are slight variations in various parts. Even if the repulsion force changes due to long-term use, it can be easily corrected to ensure reliable operation.Furthermore, it has great practical advantages, such as being versatile for various ice makers with different ice sizes. It is something.
