As shown in FIG. 8, the rotary gear 80 protrudes an ice making container coupling hole 81 for coupling an ice making container A to the front, and an annular guide rib 82 at the rear thereof. Is formed.

Therefore, as shown in FIG. 14, the rotation gear interlocking protrusion 122 of the detection lever 120 is normally kept in close contact with the outer circumferential surface of the guide rib 82, and the rotation of the rotation gear 80 is performed. And at the same time the cam (Cam) movement along the outer circumferential surface of the guide rib (82).

At this time, the one side outer circumferential surface of the guide rib 82 is formed with a detection lever operating groove (83) recessed (陷 沒) to have a predetermined length toward the center, which is the position of the detection lever 120 for the cam motion By inserting and detaching the magnetic force blocking portion 121 between the Hall sensor 110, the first magnet 84 and the second magnet 85 and the third magnet 86 by changing the On or Off function It is to induce.

In addition, the inner side of the guide rib 82 is formed with a first magnet 84, a second magnet 85 and a third magnet 86 having a predetermined angle, as shown in FIG. According to the storage capacity, it is a configuration for designating a starting point and a full ice or ice position and a stop position of the driving device.

That is, the first magnet 84 is for confirming the initial starting position, the second magnet 85 is for comparing and confirming the ice moving position and the full ice position, and finally the third magnet 86 Is for checking the stop position of the ice making container (A) rotated in the ice process.

At this time, the angle between the first magnet 84, the second magnet 85 and the third magnet 86 is to be selectively varied depending on the installation range and the driving device according to the standard to be manufactured, in the present invention The angle a between the first magnet 84 and the second magnet 85 has a range of 40 to 42 °, and the angle b between the second magnet 85 and the third magnet 86. Was formed to have a range of 115 ~ 125˚.

On the other hand, the Hall sensor 110 is a very important configuration in the present invention, in particular, in order to escape the mechanical contact method that is conventionally used, the first magnet 84, the second magnet 85 and the third magnet ( The magnetic field reaction with 86 ensures accurate and rapid response as well as durability and reliability of operation.

At this time, since the detailed configuration and operation principle of the hall sensor 110 is a known technique that is commonly used in the art, a more detailed description thereof will be omitted.

As such, due to the non-contact method of the first magnet 84, the second magnet 85, the third magnet 86, and the hall sensor 110, the accurate moving and ice level can be confirmed, as well as the conventional mechanical mechanism. The frequency of malfunctions caused by frequent failures due to the contact method can be solved at a glance.

The sensing lever 120 protrudes forward as shown in FIG. 10 or 11 to form a rotary gear interlocking protrusion 122 for cam motion along the guide rib 82, and the first upper portion of the sensing lever 120. And a magnetic shield 121 to block the magnetic force of the magnet 84, the second magnet 85, and the third magnet 86, and on one side, the inspection axis lever 131 is inserted into and interlocked. Lever lead 123 is formed.

In particular, the rotary gear interlocking protrusion 122 is interlocked along the guide rib 82, thereby placing the magnetic force blocking part 121 on the hall sensor 110, thereby allowing the first magnet 84 and the second magnet. It is a configuration for selectively blocking and opening the magnetic force between the 85 and the third magnet 86.

To this end, it will be obvious that the material of the magnetic shield 121 is to use a nonmagnetic material. In the present invention, the material of the magnetic shield 121 is stainless.

In addition, the detection axis lever inlet 123 is configured to adjust the angle of the detection lever 90 by interlocking the detection axis 130, that is, the cam motion along the outer circumferential surface of the guide rib 82. The angle of the detection lever 90 can be adjusted by raising and lowering the detection axis lever 131 according to the position change of the detection lever 120.

In this case, a spring coupler 124 protruding from the bottom of the detection lever 120 is formed, which is usually formed by forming a spring 125 between the spring coupler 124 and the lower case 10. The blocking unit 121 generates an elastic force to be positioned above the hall sensor 110.

In addition, the sensing lever 120 may be any one of the drive gear 40, the first gear 50, the second gear 60, the third gear 70, and the rotary gear 80. It can be formed so that the pivot (Pivot) can be rotated through, so as to be able to selectively apply the detection lever 120 according to the specification and size used.

Since the detection axis 130 rotates the detection axis lever 131 inserted into the detection axis lever inlet 123 when the detection lever 120 is operated as shown in FIG. As well as being able to adjust the angle of the detection lever 90, if the motion of the detection lever 90 is constrained in the process of checking the ice and the ice level, the motion of the detection lever 120 is stopped to determine the ice or ice level. It will function to confirm.

In this case, as shown in FIG. 16, an anti-rotation protrusion 132 is inserted into the insertion groove 22 formed at one side of the upper case 20 to rotate only at a predetermined angle, as shown in FIG. 16. .

The ice-making process to which the drive device for a non-contact automatic ice maker of the present invention having the above configuration is applied is as follows.

First, as shown in Figure 18, the detection lever 120 is in close contact with the upper direction by the elastic force of the spring 125 formed between the lower case 10, but the rear of the rotary gear 80 Since the rotary gear interlocking protrusion 122 is positioned on the outer circumferential surface of the formed guide rib 82, it can maintain a state in which it can no longer be lifted up. At this time, the first magnet 84 and the hall sensor 110 are mutually inclined. Since it is located so as to correspond, the sensor signal is turned on to confirm that the initial state of the ice preparation.

In particular, the magnetic force blocking portion 121 of the detection lever 120 is in close contact with the outer circumferential surface of the guide rib 82 to maintain a state that cannot be raised.

Next, as shown in FIG. 19, as the rotary gear interlocking protrusion 122 is simultaneously positioned in the detection lever operating groove 83 as the rotary gear 80 rotates, the magnetic force blocking part Since the 121 blocks the hall sensor 110 and the second magnet 85, the signal of the sensor transmits an off state, thereby confirming that it is in an iced state.

At this time, as the detection lever 120 is raised, the detection axis 130 is interlocked to rotate the detection lever 90 so that the ice storage amount in the ice storage container can be confirmed.

Next, as shown in FIG. 20, the rotary gear interlocking protrusion 122 cam-moved along the gumming lever operating groove 83 due to the rotation of the rotary gear 80 again moves to the guide lead 82. While contacting the outer circumferential surface is lowered again, at the same time the inspection lever 90 is raised to maintain the initial state.

Lastly, as shown in FIG. 21, when the rotary gear 80 detects the position of the third magnet 86 while rotating, the reverse rotation is performed to stop the rotation and return to the initial state. .

At this time, the ice making container A, which is connected to the rotary gear 80 and rotates, enables an efficient ice removing action through a separate twisting action to ice the ice.

The ice-covering process to which the drive device for a non-contact type automatic ice maker having the above configuration is applied is as follows.

First, as shown in Figure 22, the detection lever 120 is in close contact with the upper direction by the elastic force of the spring 125 formed between the lower case 10, but the rear of the rotary gear 80 Since the rotary gear interlocking protrusion 122 is positioned on the outer circumferential surface of the formed guide rib 82, it can maintain a state in which it can no longer be lifted up. At this time, the first magnet 84 and the hall sensor 110 are mutually supported. As it is located to correspond, the signal of the sensor is turned on, so it is confirmed that it is the initial state of the ice preparation.

In particular, the magnetic force blocking portion 121 of the detection lever 120 is in close contact with the outer circumferential surface of the guide rib 82 to maintain a state that cannot be raised.

Next, as shown in FIG. 23, the rotary gear interlocking protrusion 122 is raised in the upper direction of the detection lever operating groove 83 at the same time as the rotation of the rotary gear 80, wherein the lower direction As the ice detection lever 90 to check the storage amount of ice while rotating as it cannot be lowered any more due to the ice filled, the blocking portion 121 of the detection lever 120 does not rise so that the hall sensor ( Since it is impossible to block between the 110 and the second magnet 85, the signal of the sensor is transmitted to the on state, thereby confirming that it is in the full state.

Lastly, as shown in FIG. 24, when the signal of the full ice state occurs, the rotary gear 80 rotates back to return to the initial state.

Although the embodiment of the present invention has been described in detail as described above, the scope of the present invention is not limited thereto, and it is natural that the scope of the present invention is included to be substantially equivalent to the embodiment of the present invention. something to do.

As such, the present invention has the advantage of improving the efficiency and range of use of the ice maker, since the ice sensor and the ice position of the ice ice can be accurately measured using the hall sensor and the magnet.

In addition, the present invention has the advantage that it is possible to improve the durability of the drive device as well as to ensure the operation reliability by using a non-contact type Hall sensor that does not generate accuracy as well as friction by the contact by avoiding the mechanical contact method.

In particular, the present invention can reduce the manufacturing cost because the structure is simple and small, as well as can be selectively applied regardless of the size of the large refrigerator as well as the small refrigerator, so that the convenience of use and the production cost can be reduced. It is a very useful invention with advantages.
