題点がある。However, according to the above-mentioned prior art, since the magnet is located outside the ice storage, it is greatly affected by the outside air temperature, and its magnetic force fluctuates. In particular, in the case of an ice storage detection device, a heating element such as an ice maker exists around the ice storage, and the ice storage and the ice maker are covered with panels (exterior panels, interior panels, etc.) as one ice maker. , The ambient temperature of the magnet fluctuates between room temperature and about 60 ° C., and as a result, the magnetic force fluctuation of the magnet 63a also increases. Therefore, there is a problem that the amount of ice stored when the movable contact portion 63 of the switch 62 separates from the fixed contact portion 64 is not stable.

きる。As described above, according to the first embodiment of the present invention, the ice storage 30 is covered by the panels (interior panels, exterior panels) together with the heating elements such as the auger ice maker 20 and the like. For this reason, the temperature outside the ice storage 30 fluctuates greatly, but the surrounding temperature of the magnet 42 is kept at around 0 ° C. because the magnet 42 is provided inside the ice storage 30.
Therefore, the magnetic force variation due to the ambient temperature of the magnet 42 is small,
When the swing member 41 rotates from the natural state by a predetermined angle (including substantially 0 degrees), the contact between the two contact portions of the switch 44 is reliably switched from the first connection state to the second connection state. That is, the ice storage detection device can always accurately detect that a predetermined amount of ice chips IC has been stored in the ice storage 30.

れら両接点部は接続状態（第１接続状態）に保たれる。The second embodiment operates in the same manner as the first embodiment. That is, when the number of the ice chips IC in the ice storage 30 is small, the ice detecting portion 46a of the swing member 46 does not contact the ice chip IC, and the swing member 46 is maintained in a natural state. Therefore, the upper surface of the proximity portion 46b comes into contact with the lower surface of the upper wall 30a (the state shown in FIG. 3). Thereby, the magnet 4
Since the distance between the movable contact portions 7 and 47 and the movable contact portion 49a of the switch 49 is reduced, the movable contact portion 49
The attraction force of “a” exceeds the restoring force of the movable contact portion 49a, the movable contact portion 49a comes into contact with the fixed contact portion 49b, and these two contact portions are maintained in a connected state (first connected state).

The member 46 moves (rotates) in the direction indicated by the arrow in FIG.
I do. This increases the distance between the magnets 47, 47 and the movable contact 49a of the switch 49.
The suction force of the movable contact portion 49 a by the movable contact portion 49 is
The movable contact portion 49a is separated from the fixed contact portion 49b below the restoring force of the second contact portion 49a, and both contact portions are opened (the second contact portion 49a).

Is small, and when the swinging member 46 is rotated from the natural state by a predetermined angle (including substantially 0 degree), the first contact state of the switch 49 changes from the first connection state to the second connection state. Switch reliably. That is, this ice storage detecting device is an ice storage 3
It is always possible to accurately detect that a predetermined amount of ice chips IC has been stored in zero.

It is separated into two branches. Therefore, if a compressive force is applied to this portion from the left and right directions in FIG.
The distance between 46d can be reduced. Therefore, the protrusions 46c,
Since the 46d can be easily inserted into the through hole of the support member 48, the swing member 46 can be mounted very easily.

２の溝５１ｄが設けられている。Next, a modification of the first and second embodiments will be described with reference to FIG. This modification is different from the first and second embodiments only in the method of holding the magnet. Specifically, the swinging member 51 made of ABS resin includes an ice detecting portion 51a and a proximity portion 51b, and a rectangular groove having a two-step depth is provided on an upper surface of the proximity portion 51b. . That is, on the upper surface of the proximity portion 51b,
A first groove 51c having a substantially rectangular shape and a first depth;
And a second groove 51d having a rectangular shape smaller than the first groove 51c and having a second depth (deeper than the first depth) is provided at the center thereof.

1d. Next, the first resin made of ABS resin
A cover 53 having the same shape as the groove 51c is inserted into the first groove 51c to cover the upper portion of the magnet 52. Thereafter, the periphery of the lid 53 and the end of the first groove 51c are welded with methylene chloride to complete the mounting of the magnet. Note that methylene chloride does not remain because it evaporates after welding.

できる。According to such a modification, since the magnet 52 is not exposed in the ice storage 30, an ice storage detecting device which is preferable from the viewpoint of hygiene can be obtained. When the magnet is held by “fitting”, the magnet may fall off during use. On the other hand, in the present modification, since the lid 53 is fixed by welding, the magnet 52 falls off. The possibility is extremely small. Further, since the magnet 52 is held in the closed space, the magnet 52 is not affected by chlorine gas or the like generated in the ice storage 30 and can exhibit stable magnet performance.

となるので、生産コストを一層低下することができる。On the other hand, in the method of insert-molding the magnet in the resin to prevent the magnet from falling off, heat is applied to the magnet during the insert molding, so that the magnetic force of the magnet decreases. For this reason, it is necessary to restore the magnetic force by placing the swing member after the insert molding in a furnace for applying a magnetic force. On the other hand, according to the present modified example, since the above-described problem that the magnetic force is reduced does not occur, the step of applying the magnetic force again can be omitted, and the manufacturing process can be simplified. In addition, since a mold used when the swing member is placed in a furnace for applying magnetic force is not required, the production cost can be further reduced.
