FIG. 41 is an external view of a refrigerator-freezer to which a conventional automatic ice making device is applied, FIG. 42 is a schematic diagram showing a conventional automatic ice making device, and FIG. 43 is a detailed sectional view of a main part of the conventional automatic ice making device. In FIG. 41, the refrigerator 1 includes a refrigerator 2 and a refrigerator 3 disposed below the refrigerator 2. Further, a water supply tank corner 4 is provided at a lower portion of the refrigerator compartment 2 and an ice making corner 5 is provided at an upper portion of the freezing room 3. The water supply tank corner 4 and the ice making corner 5 are equipped with an automatic ice making device. I have.

As shown in FIG. 42, a water supply tank 40 is mounted in a water supply tank corner 4, and a large-diameter mounting opening 41 is provided below the water supply tank 40 so that a hand can enter. Further, a fixed amount chamber 42 is mounted on the mounting port 41. As shown in FIG. 43, the metering chamber 42 is screwed to the mounting port 41 and has a cap 44 having an outlet 43 at the center, a middle case 45 having an inlet 46 at the top, and an upper case 47 having activated carbon 48. It is composed of At the outlet 43 of the cap 44, the outlet 43 is connected to the inlet 46.
An interlocking valve 49 for opening and closing the valve is mounted. The interlocking valve 49 has an outflow valve 50 for closing the outflow port 43 and an inflow valve 51 for closing the inflow port 46, and is urged downward by a spring 52 in the figure. That is, when no force is applied from below the interlocking valve 49, the interlocking valve 49 is lowered by the spring 52, so that the inflow port 46 is opened and the outflow port 43 is closed.

The middle case 45 is fixed to the cap 44 by screwing or fitting, and an upper portion is provided with an air vent 45a. An upper case 47 is mounted on the middle case 45 by screwing, fitting, or the like.
The internal water is caused to flow into the fixed amount chamber 42.

A receiving tray 54 is provided below the mounting opening 41 in which the fixed amount chamber 42 is mounted. A driving mechanism 55 as a driving device is mounted on a water supply channel 53 provided in the receiving tray 54 and inclined downward. I have. The drive mechanism 55 raises and lowers the operating shaft 56 by the electromagnetic action of an internal electromagnetic solenoid, and pushes the interlocking valve 49 of the fixed quantity chamber 42 upward by a bell 57 attached to the tip of the operating shaft 56.
The lid 57 is for preventing water from flowing out from the outlet 43 into the mounting hole 53a of the water supply passage 53, and is made of a silicon-based material. Thereby, the driving mechanism 5
5 is operated to raise the operating shaft 56, the interlocking valve 4
9 is pushed upward, the outlet 43 opens and the inlet 4
6 will be closed by the inflow valve 51.

As shown in FIG. 42, a water supply pump 58 is installed on the tray 54 on which the drive mechanism 55 is mounted.
An extrusion hose 59 is attached to an upper end of the water supply pump 58. The extrusion hose 59 extends to the ice making corner 5 of the freezing room 3, and its tip reaches the ice tray 27 in the ice making corner 5. The water supply pump 58
Is a self-contained pump, not a spiral pump. In a self-contained pump, the pump motor rotation speed is proportional to the discharge flow rate, so that the amount of water supplied to the ice tray can be controlled by the drive time of the pump motor.

Next, the operation will be described. Drive mechanism 55
Is not operated, only the downward biasing force of the spring 52 acts on the interlocking valve 49 of the fixed amount chamber 42, so that the outflow port 43 is closed by the outflow valve 50 and the inflow port 46 is open. Therefore, in this state, the water in the water supply tank 40 enters the upper case 47 through the activated carbon 48, enters the middle case 45 through the inflow port 46, and enters the quantitative chamber 4.
2 is full. The flow of water into the middle case 45 is as follows.
The operation is smoothly performed by the operation of the air vent 45a.

Next, when the drive mechanism 55 is actuated, the operating shaft 56 is raised, and the bell 57 moves the lower end of the interlocking valve 49 to the spring 5.
Push up against the bias of 2. As a result, the outlet 43
Is opened, and the inflow port 46 is closed by the inflow valve 51, so that the water in the middle case 45 flows out of the outflow port 43 to the tray 54. The water on the tray 54 is supplied from the extrusion hose 59 into the ice tray 27 by the action of the water supply pump 58. At this time, since the inflow port 46 is closed, the amount of water flowing out to the tray 54 is substantially equal to the volume of the middle case 45. Therefore, a fixed amount of water corresponding to the volume of the middle case 45 is supplied to the ice tray 27. Since there is no air vent hole in the outlet 43, the outflow time of water is not constant, and the displacement of the amount of water in the tray 54 is not constant, but the water is immediately sucked by the self-supply type water supply pump 58. No water remains in the tray 54. That is, even if the outflow time of the water varies, the water is supplied to the ice tray 27 in a constant amount without remaining in the tray 54.

FIG. 44 shows a driving mechanism 55 and a water supply pump 58.
FIG. 4 is a schematic diagram showing a control board for controlling the operation of FIG.
5, FIG. 46 is a time chart thereof. The control board 60 is provided in the refrigerator 1 and is connected to the drive mechanism 55 and the water supply pump 58. Reference numeral 61 denotes a power supply for the control board 60.

As shown in FIG. 45, when a water supply start signal is output from the control board 60, the drive mechanism 55 is turned off.
Is turned ON for a certain time after At this time, a timing is set such that the water supply pump 58 is turned on from the OFF state for a certain time after t1 seconds. Further, as shown in FIG.
The timing may be set such that the water supply pump 58 is turned on from OFF for a certain period of time after t2 seconds after 5 is turned on.

The water collected in the tray 54 by the operation of the driving mechanism 55 is absorbed by the water supply pump 58, and the tray 54 is emptied. A gear box 28 is provided on the freezer compartment 3 for rotating the ice tray 27 to de-ice. The gear box 28 detects the amount of ice accumulated in the ice storage box. When the amount of ice is insufficient, a water supply start signal is output. Output from the control board 60.

BEST MODE FOR CARRYING OUT THE INVENTION

Embodiment 1 of the Invention Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a cross-sectional view of a refrigerator to which the automatic ice making device according to the embodiment of the present invention is applied, and FIG. 2 is a cross-sectional view showing the automatic ice making device of the embodiment of the present invention. In FIG. 1, a refrigerator 1 includes a refrigerator 2 and a refrigerator 3 disposed below the refrigerator 2. A water supply tank corner 4 is provided in a concave portion formed by bending a partition wall for partitioning the refrigerator compartment 2 and the freezer compartment 3, and an ice making corner 5 is provided behind the resulting convex portion of the freezer compartment 3. Have been.

As shown in FIG. 2, the water supply tank 10 is mounted in a water supply tank corner 4 provided on a partition wall 6 for partitioning the refrigerator compartment 2 and the freezer compartment 3.
The upper opening of the lid 12 has a small-diameter vent hole 34.
Is closed with the packing 11 interposed therebetween.
In the water supply tank 10, a sub-chamber 17 for measuring a fixed amount of water is provided integrally with the water supply tank 10, and an opening of the sub-chamber 17 is provided with a packing B16 interposed therebetween. Is closed with a pipe unit. The pipe unit includes a flange 18 as a partition plate that closes the opening of the sub-chamber 17 to partition the inside of the water supply tank 10 into the main chamber 30 and the sub-chamber 17, a packing B 16 attached around the flange 18, and a water tank 10. Water absorption pipe 13 for absorbing water to the outside, air vent 14 and main chamber 30 of water supply tank 10
A small-diameter hole 15 for guiding water from the water to the sub-chamber 17 is integrally formed. The water absorption pipe 13 and the air vent 14 communicate with the outside of the water supply tank 10, and the activated carbon water purification filter 23 is fixed to the main chamber 30 from the small diameter hole 15 of the pipe unit using a filter fixing member 33. The capacity of the sub-chamber 17 is formed to be slightly smaller than that of the ice tray 27.

The water absorption pipe 13 which has come out of the water supply tank 10
The water tank 10 does not protrude from the upper surface of the partition wall 6.
, The water channel is turned downward and connected to the suction pipe 22 fixed to the partition wall 6. A packing C21 is attached between the water absorption pipe 13 and the suction pipe 22, and a latch 20 for improving the close contact between the three members.
Are fixed to the suction pipe 22 together with the coil spring 32. The end portion 13a of the water absorption pipe 13 on the side of the suction pipe 22 is always located above the water level in the water supply tank 10 when the water is full.

Numeral 24 denotes a pump for supplying water from the water supply tank 10 to the ice tray 27. In this embodiment, a self-supplying pump is used. A spiral pump or the like may be used, but if a self-contained pump is used, the water tank 1
Wiring and the like when attaching / detaching 0 are facilitated. Between the suction pipe 22 and the self-contained pump 24, a sub-pipe 25 formed of a soft material that does not interfere with the Food Sanitation Law is interposed. The same applies to the discharge side of the self-contained pump 24. The transmission of the vibration of the self-contained pump 24 to the suction pipe 22 and the discharge pipe 26 is suppressed as much as possible by the sub-pipe 25. A discharge pipe 26 is connected to the discharge side sub-pipe 25.
The water is led to the ice tray 27 located at. The suction pipe 22, the sub pipe 25, and the discharge pipe 26 penetrate the partition wall 6, and are connected to each other to form a supply pipe which is a pipe for supplying water to the ice tray 27. The ice tray 27 is fixed to the partition wall 6 together with a gear box 28 for applying a torsional moment to the ice tray 27 to separate ice. The partition wall convex portion 29 on the freezer compartment 3 side of the partition wall 6 overlaps the ice tray 27 and the gear box 28 in the vertical and horizontal directions. Further, the water supply tank 10, the ice tray 27 and the gear box 28 also overlap in the left-right direction and the up-down direction.

The water supply tank 10 is attached to the water supply tank corner 4 after water is poured into the water supply tank 10 and the pipe unit, the packing 11 and the lid 12 are set in the water supply tank 10. The water supply tank 10 is installed from above the partition wall 6 and, at the same time as the water tank 10 is installed.
A connection is made between the water absorption pipe 13 fixed to the side and the suction pipe 22 fixed to the partition wall 6.

When the pipe 13 starts to be inserted into the suction pipe 22, the latch 20 fixed to the suction pipe 22 is pushed away against the spring force of the coil spring 32. The pipe 13 compresses the packing C21 fixed in the suction pipe 22, and the latch 20 rides over the stopper 19 of the pipe 13 in a state where the airtightness can be secured, thereby fixing the pipe 13 and the suction pipe 22 in the axial direction. In this manner, the water supply tank 10 is installed so as to be completely buried in the water supply tank corner 4 which is a concave portion provided in the partition wall 6. When the tank 10 is removed, the above operation is reversed, and the removal of the tank 10 causes the pipe 13 and the suction pipe 22 to be removed.
Is also disconnected.

Next, the operation of supplying water from the water supply tank 10 to the ice tray 27 will be described. While the automatic ice making device is on standby, the sub-chamber 17 in the water supply tank 10 is filled with water. When the operation of the automatic ice making device is started and the water supply operation is started, the gear of the self-contained pump 24 starts rotating in the direction of sending water to the ice tray 27 side while meshing. Self-contained pump 24
The amount of water in the sub chamber 17 decreases in proportion to the rotation speed of
At this time, since water flows into the sub-chamber 17 only from the small-diameter hole 15, the amount of water is small compared to the amount of water carried out of the sub-chamber 17 by the self-contained pump 24. The self-contained pump 24 stops rotating until the water level in the sub-chamber 17 becomes almost zero and no water remains in the pipe 13, the suction pipe 22, the self-contained pump 24, and the discharge pipe 26. The supply ends.

This operation will be described with reference to FIGS. FIG. 3 is a schematic diagram showing a control board for controlling the operation of the self-contained pump 24, and FIG. 4 is a time chart thereof. In FIG. 3, reference numeral 50 denotes a control board, to which the self-contained pump 24 and the power supply 51 are connected, and which is provided in the refrigerator 1. When the gear box 28 detects the amount of ice accumulated in the ice storage box and detects that the amount of ice is insufficient,
The control board 50 outputs a water supply start signal. When the water supply start signal is output from the control board 50, the self-contained pump 24
Is turned on for a certain time from OFF. When the self-contained pump 24 operates, the water in the sub chamber 17 in the water supply tank 10 is absorbed by the self-contained pump 24 and supplied to the ice tray 27.
At this time, the inside of the sub-chamber 17 becomes empty, but water enters the sub-chamber 17 from the small-diameter hole 15 at a very low speed, and the sub-chamber 1
The inside of 7 becomes full. Thereafter, when the amount of ice is insufficient again, the self-contained pump 24 operates to supply water to the ice tray 27, and this operation is repeated.

As described above, according to the automatic ice making device of the embodiment of the present invention, the water supply tank 10 is formed so that the upper surface is substantially flush with the water supply tank corner 4 formed in the partition wall 6 in a concave shape. Since it is installed, it is possible to install a case that can move back and forth on the floor surface of the refrigerator compartment 2, that is, on the upper surface of the partition wall 6 with full width. In addition, since a fixed amount of water is structurally supplied so that there is no residual water in the pipe, dirt in the pipe due to water decay can be suppressed, and a constant amount of water is always supplied to the ice tray 27. it can. Since the discharge-side end of the pipe 13 attached to the water supply tank 10 is located above the full water level in the water supply tank 10, the water supply tank 10 is operated during the operation of the self-supplying pump 24.
Even if the pipe 13 and the suction pipe 22 are disconnected from each other, the amount of water flowing out of the water supply tank 10 is minimized, so that the outflow of water can be prevented from stopping. Furthermore, since the vibration of the self-contained pump 24 is suppressed from being transmitted to the refrigerator 1, a system with a small operating noise can be configured.

In the first embodiment of the present invention, the partition wall 6 is bent so that a concave portion is formed on the upper portion and a convex portion is formed on the lower portion. However, the concave portion is formed only on the upper portion of the partition wall 6. You may make it. The recess may be formed in the lower part of the partition wall, in which case the water supply tank 10
May be configured to be attached from below.

In the first embodiment of the present invention, the water supply tank 10 is filled with water, and then the pipe unit and the like are set. However, the lid 12 is provided with a water supply port, and the pipe unit and the packing are provided. After setting the lid 11 and the lid 12 in the water supply tank 10, water may be poured into the water supply tank 10 through the water supply port. In this case, the water that has entered the main chamber 30 from the water supply port enters the sub-chamber 17 through the small-diameter hole 15, and the air in the sub-chamber 17 is discharged to the outside of the water supply tank 10 through the air vent 14. Further, when water is poured into the water supply tank 10, air is discharged from the ventilation holes 34 provided in the lid 12.

Embodiment 2 of the Invention Embodiment 2 of the invention
Is a modification of the automatic ice making device having the same configuration as that of the first embodiment of the present invention described above, but with a different control method. The operation in the embodiment of the present invention will be described with reference to the flowchart of FIG. When the power is turned on, first, the self-contained pump 24 performs a reverse operation for a predetermined time and discharges water remaining in the pipe to the water supply tank 10 side. Next, when the gear box 28 detects that the amount of ice is insufficient,
The self-contained pump 24 performs normal rotation for a predetermined time, and water is supplied to the ice tray 27. When the water in the pipe is discharged into the water supply tank 10, if the diameter of the air vent 14 is increased, the water in the water supply tank 10 does not leak from the air vent 14 to the outside.

According to the embodiment of the present invention, power supply to the refrigerator 1 is stopped during operation of the self-contained pump 24 due to a power failure or the like, and the pipe 13, the suction pipe 22, the self-contained pump 24, the discharge pipe 26 Even if water remains in the pipe, when the power is supplied again, the self-contained pump 24 performs a reverse operation and discharges the water remaining in the pipe to the water supply tank 10 side. The water runs out, and a fixed amount of water can always be supplied to the ice tray 27, thereby preventing the water from being supplied over the capacity of the ice tray 27.
