Abstract

PURPOSE:To provide an automated ice making apparatus wherein lumps of ice are separated by rotating an ice making pan in the same direction. CONSTITUTION:An ice making pan 3 is rotated with a first driving device 5 composed of a motor 8, etc., and during one revolution of the ice making pan 3 a stopper 6 is pushed out from the driving device 2 with a second driving device 7 to twist the ice making pan 3 in contact with a protrusion A15 of the ice making pan 3. Hereby, lumps of ice are exfoliated from the ice making pan 3.

Description

Detailed Description of the Invention

[0001]

The present invention relates to a general automatic ice making device,
In particular, it relates to a technique for peeling an ice block from an ice tray.

[0002]

2. Description of the Related Art As disclosed in Japanese Utility Model Publication No. 50-8293, an automatic ice making device which has been conventionally used is such that the operation of peeling an ice block from an ice making tray is performed after the ice making is completed. It is rotated 180 degrees or more by a driving source such as the above, and the ice tray is twisted to remove the ice from the ice tray. After that, the drive source was reversed and the ice tray was returned to the normal position. A very complicated circuit was required also in terms of electrical control.

[0003]

However, in the above-mentioned structure, it is necessary to rotate in one direction by a predetermined angle and then rotate in a direction opposite to the above direction by a predetermined angle.
A forward and reverse circuit was required for electrical control.

The present invention has been made in view of the above problems, and provides an automatic ice making device for peeling an ice block from an ice tray by rotating in one direction.

[0005]

In order to solve the above-mentioned problems, the automatic ice making device of the present invention always rotates a motor or the like as a drive source in a fixed direction. In addition, the stopper that causes the ice tray to be twisted also has a structure in which it is driven in the direction coaxial with the drive source.

[0006]

According to the present invention, since the ice tray can be always rotated in a fixed direction to separate the ice blocks by the above-described structure, the motor for rotating the ice tray needs to be provided with the forward and reverse circuits as electric control. It is possible to provide a control device which is easy to control and inexpensive.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS.

FIG. 1 shows an overall view of an automatic ice making device. 1 is an automatic ice making device, which is a drive device 2, an ice making plate 3, and an ice making plate 3
And an ice tray supporting frame 4 for supporting the. The drive device 2
Is a first drive device 5 that rotates the ice tray 3 and a second drive device 7 that drives a stopper 6 that stops the rotation of the ice tray 3.
Is built in.

The first drive unit 5 comprises a motor 8 and a transmission mechanism 9 for rotating the ice tray 3. The second drive device 7 is
A gear 10, a cam 11 and a spring 12 are incorporated which are driven by the first drive device 5 and actuate the stopper 6.

The transmission mechanism 5 and the ice tray 3 are directly connected by a drive shaft 13. A rotating body 14 is arranged on the drive shaft 13. As shown in FIG. 3, the ice tray 3 is provided with protrusions on the left and right,
The drive shaft 13 includes a protrusion 15 that abuts the stopper 6, a protrusion 16 that abuts the rotor 14, and a drive shaft 13.

Then, the protrusion 16 of the ice tray 3 and the rotating body 1
When the motor 8 rotates, the drive shaft 13, the rotary body 14, and the ice tray 3 start rotating by the transmission mechanism 9. At the same time, the gear 10 also starts moving, the cam 11 also starts rotating, and the operation of pushing out the stopper 6 starts.

Further, the rotation angle R of the ice tray 3 is 90 <
When a certain angle within the range of R <270 is reached, the tip of the cam 8 farthest from the rotation axis is in a state of pressing the stopper 6,
When the protrusion A15 of the ice tray 3 and the stopper 6 are brought into engagement with each other, the other end of the ice tray 3 stops rotating.

However, since there is no obstacle on the other end side of the ice tray 3, the ice tray 3 continues to rotate. At this time, the ice tray 3 is twisted and the ice blocks are separated from the ice tray 3.
After the ice blocks are separated from the ice tray 3, the drive shaft 13 continues to rotate. At this time, since the cam 11 is also rotating at the same time, the distance of the contact portion with the stopper 6 from the position farthest from the rotation axis of the cam 11 to the position closer to the rotation axis uses the force of the spring 12 as a medium to cause the stopper 6 to move. The operation of pushing back to the drive device 2 side starts.

Then, the projection A15 of the ice tray 3 and the fitting portion of the stopper 6 are disengaged, the other end of the ice tray 3 also starts to rotate again, and finally the ice tray 3 rotates once to complete the ice removal. .

[0015]

As described above, according to the present invention, while the ice tray is rotated once, the protrusion of the ice tray and the stopper start to work in synchronization with the rotation of the ice tray, so that the ice tray is twisted. Occurs, which has the effect of making the ice block easily peel off from the ice tray.
