Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a water supply device for an ice tray that can be applied to an automatic ice making machine.

[0002]

[Prior Art]

 Refrigerators with an automatic ice-making machine that automatically supply water when ice-making trays run out are becoming popular. FIG. 4 shows an example thereof, and a refrigerating room 4 is arranged below the freezing room 2.

The ice tray 1 is placed in the freezer compartment 2, and the water supply tank 3 for storing water for ice making is placed in the refrigerating compartment 4, respectively. Since water is supplied to the ice tray 1 under the water supply tank, It is carried out by a fixed amount pump.

On the other hand, recently, as shown in FIG. 3, a refrigerator in which a freezer compartment 2 is arranged below a refrigerating compartment 4 has been developed. However, the water is still supplied to an ice tray by a fixed-quantity feeding method using a pump. Has been taken.

[0005]

[Problems to be solved by the device]

 It is difficult to consistently and consistently supply the amount of water supplied to the ice tray with the conventional fixed-quantity feed, and variations are inevitable. An object of the present invention is to provide a means capable of providing a fixed amount of water to an ice tray in a constant amount, together with the advent of a refrigerator in which a freezing compartment is arranged below a refrigerating compartment.

[0006]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention provides a water tray under a water supply tank, a weight for moving in and out of the water tray, and a water supply path for guiding water to an ice tray in the upper portion of the water tray. did.

Here, it is effective to provide a drive means for repeatedly moving the weight in and out.

[0008]

[Action]

 The amount of water that overflows when the weight sinks into the water in the water pan is supplied to the ice tray.

[0009]

【Example】

 As described with reference to FIG. 3, the ice tray 1 is arranged below the water supply tank 3. In FIG. 1, a water tray 5 is provided between the water supply tank 3 and the ice tray 1. An upper part of the water supply channel 6 communicates with an upper part of the water receiving tray 5, and a lower part of the water supply channel 6 opens to an upper part of the ice tray 1.

A pulley 7 is arranged above the water tray 1, and a weight 10 is hung from the tip of a string 9 via the pulley 7. The other end of the string 9 is attached to the eccentric position of the rotary plate 11 via the pulley 8.

The rotating plate 11 is attached to the shaft of a motor, and the weight 10 moves in and out of the water receiving tray 5 by the rotation of the rotating plate 11 accompanying the driving of the motor. Therefore, the pulleys 7 and 8, the string 9, the rotary plate 11 and the like constitute a driving means for moving the weight 10 into and out of the water tray.

The manner in which water is supplied will be described with reference to FIGS. 1 and 2. As a premise, water is supplied from the water supply tank 3 to the water tray 5 so that a predetermined water level is maintained.

When the ice of the ice tray 1 is taken out, the situation is detected by the sensor, and the water supply instruction P1 is given to the water supply device. Based on this water supply instruction, the motor is rotated by a predetermined amount to rotate the rotating plate 11, and the weight 10 that was located above the water tray 5 moves down by its own weight until it sinks into the water (IN The overflow water is supplied to the ice tray 1 through the water supply path 6 according to the above.

When the weight 10 reaches the bottom of the ice tray 1, the driving of the motor is stopped. After waiting for the water surface of the water tray to stabilize (time t1), the motor is started and the weight is pulled up (OUT). Then, after waiting for the water in the water supply tank to collect in the water receiving tray 1 (time t 2), the weight 10 is submerged in the water receiving tray 1 again. This operation is performed until a predetermined amount of water is supplied to the ice tray 1. Figure 2 shows an example where the weight is sunk repeatedly.

As described above, when the size of the weight to be put in the water receiving tray 5 is not set to a size that satisfies the required amount in one time, and the number of water supply operations is satisfied by the product of the weight and the volume of the weight. This has the advantage of reducing the volume of the weight and the size of the water pan, thus increasing the effective storage capacity of the refrigerator.

As described above, the amount of water supply is determined by the volume of the weight, so that the variation in the amount of water supply is extremely small. In addition, compared to conventional water supply by pump, there are advantages such as no high-speed rotation part, quiet operation and long life.

[0017]

[Effect of the device]

 According to the present invention, it is possible to provide a fixed amount of water to an ice tray without variation.

[Correction content]

When the ice in the ice tray 1 is taken out, the situation is detected by the sensor, and the water supply instruction P1 is given to the water supply device. Based on this water supply instruction, the motor is driven to rotate the rotary plate 11 by a predetermined amount, and the weight 10 which has been positioned above the water tray 5 moves downward by its own weight and sinks into the water (IN The overflow water is supplied to the ice tray 1 through the water supply passage 6 in accordance with (1).

[Correction content]

As described above, the size of the weight to be put in the water receiving tray 5 is not set to a size that satisfies the total amount required at one time, and the number of water supply operations is calculated by multiplying the volume of the weight entering the water receiving tray 1 by the product. If filled, the volume of the weight is reduced and the size of the water pan can be reduced, which has the advantage of increasing the effective volume of the refrigerator.
