Description

[Detailed Description of the Invention] This invention relates to an ice dispenser device, and particularly relates to a novel improvement for preventing the thrust load applied to the screw blades from being applied to the output shaft of the motor.

In conventionally used devices of this type, the screw shaft and screw blades were attached directly to the output shaft of the motor, so the thrust load applied to the screw blades when discharging ice was applied directly to the output shaft of the motor. As a result, an unreasonable load is applied to the reduction gear of the motor, which is a major cause of motor failure.

The purpose of this invention is to provide an extremely effective means to quickly eliminate the above-mentioned drawbacks.In particular, the thrust load receiver is provided with a member on the motor mounting plate, and the thrust load receiver is installed on the output shaft of the motor. The coupling member is connected to the thrust load receiver, and a Z-type waterproof ring is installed between the coupling member and the thrust load receiver, and the coupling member is attached to the screw shaft provided on the coupling member. The thrust load receiver is configured so that the load is applied to the member so that the load is not applied to the motor output shaft.

A preferred embodiment of the ice dispenser device according to this invention will be described in detail below with reference to the drawings.

In the drawings, the reference numeral 1 indicates a motor, and this motor 1 is provided with a speed reduction mechanism 2 .

A thrust load bearing member 5 made of resin and having a taper drain hole 4 is attached to the motor mounting plate 3 of the speed reduction mechanism 2, and the motor output shaft 6 of the speed reduction mechanism 2 protrudes from the taper hole 4 for draining. There is.

A coupling member 7 is fitted into the outer periphery of the motor output shaft 6 via its hole 8, and a screw shaft 10 having screw blades 9 is further fitted into the outer periphery of the coupling member 7. The screw shaft 10 and the coupling member 7 are integrated with a bolt 11.

A waterproof ring 5a having a Z-shaped cross section is provided between the coupling member 7 and the thrust load receiver member 5 to provide waterproof protection to the motor 1.

Furthermore, a coupling groove 1 formed in the center of the motor output shaft 6
As shown in FIG. 2, a key member 13 is installed inside the motor output shaft 6, and the movement of the key member 13 is regulated by a spring pin 14 without being fixed. The ring member 7 and the ring member 7 are provided so as to be able to slide with each other, and the thrust load of the screw shaft 10 is canceled against the output shaft 6 during this sliding, so that the coupling member 7 that moves together with the screw shaft 10 does not receive the thrust load. The thrust load receiver abuts against the member 5 and is further applied to the motor mounting plate 3 via the member 5.

To explain the case of operating the ice dispenser configured as above, by rotating the motor 1, the motor output shaft 6, the key member 13, the coupling member 7, and the screw shaft 10 are The screw blade 9 is rotated by the rotational movement.

In this case, when ice (not shown) is sent by the screw blade 9 in the direction of arrow A, a thrust load thereon is applied directly to the screw shaft 10, and normally this thrust load is applied to the motor output shaft 6. In the configuration of the present invention, since the coupling member 7 and the motor output shaft 6 are slidable relative to each other, the thrust load is canceled and the thrust load when the key member 13 collides with the spring pin 14 is reduced. is coupling member 7
The tip of the thrust load receiver only collides with the member 5 and is not transmitted to the motor output shaft 6, so that the motor output shaft 6 is not damaged.

In addition, since the waterproof ring 5 is also made of flexible material,
It can follow deformation and has an extremely high waterproof effect.

The ice dispenser device 20 configured as described above is attached to the ice making device shown in FIG. 3 to supply ice 21 to the outside, and when the ice 21 formed on the ice making plate 22 is removed, the ice 21 is removed. It is dropped into a cut heater 23, divided into small pieces, and stored in a water storage tank 24.

The stored ice 21 is discharged to the outside by operating the ice dispenser device 20 as needed.

Since the ice dispenser device according to this invention has the above-mentioned structure and operation, the thrust load generated on the screw shaft when dispensing ice is completely removed, so there is no damage to the motor output shaft and motor. A failure-free ice making device can be obtained.

In addition, the Z-shaped waterproof ring prevents water from leaking into the motor, so stable rotational operation can be achieved over a long period of time.

Even in the unlikely event that the waterproof ring is damaged, any leakage water will be drained to the outside through the drain taper hole, so water will not enter the motor/reducer unit.
