DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below with reference to the accompanying drawings.

In order to realize the present invention, although not shown in FIG. 1, the water supply hose 1 is connected to a water supply tank, and the water supply to the water supply hose 1 is performed by a water supply pump. In addition, the water tank and the water supply motor are provided with a fixing tool for fixing the position of the water supply motor and the water supply motor at appropriate positions in the freezing chamber.

Furthermore, in order to carry out the invention, in relation to the microprocessor used in the invention,
Not only the ice making sensor, but also a sensing means such as a micro switch that can determine whether the water tank is installed, a micro switch that senses whether the ice machine is installed, a micro switch that senses the water supply amount, a micro that senses the reverse rotation of the motor. A switch, a micro switch for detecting whether the ice-making container is in a horizontal state, an ice-making receiving ice amount detection sensor, a presence / absence detection sensor, and the like are connected.

With the above construction, the present invention controls the operation of the ice making machine as shown in FIGS. That is, the ice releasing method of the ice making machine according to the present invention is as follows.

First, in the water supply stage 300, the microprocessor detects whether the ice making container 4 of the automatic ice making machine 2 is maintained in the horizontal state through the horizontal state detecting sensor, and operates the water supply pump to supply the water supply hose 1. Water is supplied via. In the water supply completion determination step 301, the water supply completion is determined by a signal input that senses the weight of the water supply amount of the ice making container, and the water supply is continued until the water supply is completed. Water supply stage 3
When the completion of water supply is confirmed in 01, the process proceeds to step 302, and the ice making of the water in the ice making container 4 is started. And
The ice making is completed through the step 303 of judging the ice making state while sensing the ice making temperature state by the ice making sensor 5 mounted on the ice making container 4.

When the ice making is completed in this way, step 304
Then, the presence or absence of the ice maker 9 is determined by a micro switch that senses the presence or absence of the ice maker. At this time, if the ice tray 9 is not installed, the process proceeds to step 304A for issuing a warning sound, and step 304 is performed again after the elapse of a predetermined time. If the ice tray 9 is installed in step 304, the ice receiving amount detection determination step 30
Moving to 5, it is judged by the ice amount detection sensor whether or not there is a lot of ice in the ice tray 9. Here, if it is determined that the storage cannot be performed more than the stored amount, the process proceeds to step 305A, a warning sound is emitted to notify the user of the ice recovery, and a predetermined time elapses. After that, step 304 is performed again. If it is determined that the amount of ice in the ice tray 9 is less than or equal to a predetermined amount, that is, the amount of ice currently stored does not hinder the storage of the amount of ice to be newly stored, the first ice making The process moves to the container rotation maintaining step 306.

In step 306, the motor 6 mounted inside the automatic ice maker 2 and the gear (not shown) interlocking with the motor 6 are driven to complete the ice making, and the ice making container 4 is shown in FIG. Then, it is rotated counterclockwise while being maintained for a predetermined time. As a result, the locking projection 7 on the outer peripheral edge of one side of the ice making container 4 contacts the fixing bracket 3, and when the motor 6 is further driven, the stopper 8 applies a twisting force to the ice making container 4 about to rotate. By adding, the ice made in the inside is primarily separated from the ice making container 4. That is, the contact time between the stopper 8 and the right side surface of the ice making container 4 is about 25 seconds, and it works in the arc area A where the twisting completion angle is about 25 degrees.

Next, in step 307, the ice making container 4
As shown in FIG. 4, if the ice making container 4 is kept rotating in the clockwise direction opposite to the rotation direction of the first ice making container rotation maintaining step 306, the stopper 8 and the right side of the ice making container 4 are rotated. Contact a surface. Here, the contact time is about 25 seconds, and it works in the arc area where the arc angle of twist is about 25 degrees.

After that, since the ice making container 4 is continuously rotated in the clockwise direction, the locking projection 7 is engaged with the stopper 8 via the twist region A.
Rotate until is touched.

At this time, the ice making container 4 exerts a twisting force on the ice making container 4 by the force of continuous rotation and the force of stopping the stopper 8 formed on the fixed bracket 3. Then, the ice in the ice making container 4 is separated and dropped.

When the ice is completely separated from the ice making container 4 and falls, it is judged at step 308 whether the reverse rotation detection switch is turned on, and the ice making container 4 is returned to the normal position. Determine if you did. If not, the process returns to step 307 to rotate the ice making container 4 forward. Next, in a state where the ice making container 4 is returned, the process proceeds to the returning step 309, and the ice making container 4 is continuously rotated in the reverse direction so that the locking projection 7 is brought into contact with the fixing bracket 3. ..

Thereafter, a step 310 of judging completion of the ice-making container restoration
At, the microprocessor detects whether the horizontal position detection switch is turned off with respect to the original position of the ice making container 4, and completes the ice removal of the ice making container 4.
