The conventional refrigerator with an automatic ice maker having such a structure has the following problems. (1) In order to supply a certain amount of water to the ice tray, it is necessary to store water in the fixed amount tray. Since the fixed quantity dish is constantly in contact with the air in the refrigerating chamber, it contacts the air in the refrigerating chamber while water is present in the dish, and the water absorbs odorous components in the air. Therefore, there is a problem that when ice is made, the ice smells slightly.

(2) When water is stored in a fixed quantity plate for a long time (when ice is not used, ice in the ice bank is not reduced, and ice making and ice removing operations are not performed), There is a risk that dust, miscellaneous bacteria, etc., may enter the refrigerating compartment and cause mold and the like.

(3) In a so-called top-mounted refrigerator in which a refrigerating compartment is located below the freezing compartment, a water supply to the ice tray is a pump because an ice tray is installed in the freezer compartment and a water bottle is installed in the refrigerating compartment. To use. Therefore, there is a problem that the cost becomes high.

(4) Regarding the above items (1) and (2), it is necessary to provide a cover on the front surface of the water bottle. For this reason, when the water bottle is attached or detached, the water bottle cannot be attached or removed without operating this cover, which is not only convenient, but also causes a cost increase.

Further, the water bottle 8 is integrally formed with a water bottle body 8a and a water inlet having a constricted portion 8b and a screw portion 8c. A constricted portion 8b and a screw portion 8c are provided on the inner lid 45 side. The lid 45 is formed so that the connecting portion between the lid 45 and the container 44 is near the lower surface of the water bottle 8 as shown in FIG. Therefore, since the welded portion is located below the water level line in the water bottle 8, even if the welded portion has a small pinhole or the like, the pinhole is always closed by the surface tension of water. As a result, water does not leak or air does not enter the water supply bottle 8 through the pinhole, so that the ice-making operation is less affected.

Reference numeral 21 denotes an air vent pipe, which communicates the metering chamber 14 with the inside of the water supply bottle body 8a as shown in FIG. 2, and when the water in the metering chamber 14 flows out to the water receiving base 9 side. The air is sent to the upper chamber of the partition plate 15 so that water flows into the fixed amount chamber 14 through the small holes 15a. Further, the air vent pipe 21 is located right above the push rod 13a and also serves as a guide member when the push rod 13a is pushed upward. Further, by doing so, the water film formed in the air vent pipe 21 by the surface tension or the like is destroyed, so that the air can be circulated reliably.

A packing 22 is provided at the contact portion between the partition plate 15 and the inside of the constricted portion 8b of the water bottle, and the packing 22 covers the cap 16 with the threaded portion 8 of the constricted portion 8b.
When it is fastened to c, it is interposed between the partition plate 15 and the constricted portion 8b in a slightly compressed form to perform water sealing. Reference numeral 9 denotes a water receiving table, and the water receiving table 9 is located at a lower portion of the metering chamber 14 which is a water supply port of the water bottle 8. Also, 12
Is a solenoid incorporated in the water pedestal 9, and its iron core 1
2a is at a position facing the push rod 13a of the valve 13. Two
A baffle plate 3 is provided so as to surround the upper portion of the water supply conduit 11 as shown in FIGS. 3 and 4, and has a small hole 23a at the bottom.

Next, the operation of such an automatic ice making machine will be described. As for the water in the water bottle 8, the push rod 13 a of the valve 13 provided in the lower portion of the metering chamber 14 is the iron core 1 of the solenoid 12.
By being pushed up by 2a, a certain amount of water flows out to the side of the water cradle 9. The water that flows out flows through the water receiving stand 9 and the water supply conduit 1
To 1. Here, it will be described that when the solenoid 12 is operated, a certain amount of water, for example, 100 cc of water, comes out to the water pedestal 9.

First, the solenoid 12 has its operating time controlled by a control board or the like, which is not shown in the figure. For example, it pushes up the push rod 13a for about 6 to 10 seconds to open the valve 13 portion. Is. As a result, the water in the fixed quantity chamber 14 formed in the water supply bottle 8 is about 80 to 90.
When cc comes out, through the small hole 15a provided in the partition plate 15 that divides the inside of the water supply bottle 8, about 100 cc of water, which is the sum of 10 to 20 cc of water entering into the fixed quantity plate 14, is supplied to the water receiving base 9 side. It comes out.

Next, the flow of water flowing into the water supply conduit 11 will be described with reference to FIGS. 3 to 6. At the time when a water supply instruction to the ice tray 24 to be described later is issued, the solenoid 12 operates and the iron core 12a is preset for a time, for example, 6 to
For 10 seconds, the push rod 13a operates to push up against the spring 13b. As a result, the valve 13 provided on the push rod 13a is opened, and the water in the fixed amount chamber 14 flows out to the water pedestal 9. The water flowing out to the water pedestal 9 is suppressed by the baffle 23 in front of the water supply conduit 11 to suppress the momentum of the water.
It reaches one.

Since the water flowing through the water pedestal 9 reaches the water supply conduit 11 through the small hole 23a of the baffle plate 23, not only the amount of water is limited but also the speed of the flowing water is reduced. It Then, the water supply bottle 8 that has passed through the water supply conduit 11
The water inside is supplied to the ice tray 24 as shown in FIG.

When it is detected that the water in the ice tray 24 is completely frozen, the mechanical section 26 starts operating and instructs the ice tray 24 to rotate. The ice tray 24 that has received the instruction is rotated by the operation of the mechanical section 26, and the ice made from the ice tray 24 is released from the ice tray 24 into the ice bank 27. The ice tray 24 returns to the horizontal state when the ice removal is completed. At this time, the solenoid 12 described above operates and the water in the water supply bottle 8 is passed through the water supply conduit 11 to supply a fixed amount of water to the ice tray 24. By repeating this operation automatically, a predetermined amount of ice can be stored in the ice bank 27.

Here, another embodiment of the baffle plate in the water receiving base 9 is shown in FIG. FIG. 5 shows an example in which the baffle plate 23 shown in FIG. 4 is made integrally with the water pedestal 9, and the same effect as the example of FIG. 4 can be obtained. In the example shown in FIG. 5, ribs 28 are provided around the inlet of the water supply conduit 11 to prevent water flowing through the water receiving base 9 from suddenly entering the water supply conduit 11. That is, the water flowing through the water pedestal 9 is limited in its force and amount by the small holes 29 provided in the ribs 28.

The reason why this water force and the amount of water are limited will be described below. In the conventional automatic ice maker of this type, as shown in FIG. 9, the tip of the water supply conduit 43 opens near the ice tray 35, and even if the water has some momentum, the water discharged from the water supply conduit 43 is I was trying not to jump out of the ice tray 35. In this embodiment, the water supply conduit 11
As shown in FIG. 6, water is supplied to the ice tray from directly above the ice tray 24 and outside the locus of the rotating ice tray 24.

That is, the distance from the tip 11a of the water supply conduit 11 to the ice tray 24 is several times greater than in the conventional case. Therefore, when trying to inject water from this position toward the ice tray 24, there is a high possibility that the water will jump out of the ice tray 24 if the water is vigorous or if there is a large amount of water.

In addition to the above effects, the baffle plate 23 of this embodiment also has the effect of preventing the cold air in the freezer compartment 3 from entering the refrigerating compartment 2 side through the water supply conduit 11. Further, as shown in the figure, the relationship between the water bottle 8 and the water receiving base 9 is that the cap 16 of the water feeding bottle 8 is detachably attached so as to cover the water flowing part of the water receiving base 9. Therefore, the water receiving table 9 is designed to have a structure in which it does not come into direct contact with the air in the refrigerator compartment.

According to the above-mentioned embodiment, the following effect can be obtained. (1) The refrigerator with an automatic ice maker according to the present embodiment has a refrigerator 2 and a freezer compartment 3 arranged in this order from the top, with a water supply section 7 on the refrigerating compartment 2 side and an ice making section 25 on the freezer compartment 3 side. The refrigerator is installed, and a constricted portion 8b is formed in the water bottle 8 and the constricted plate 15 provided on the side of the cap 16 with a valve is brought into contact with the constricted portion 8b to be surrounded by the partitioned plate 15, the constricted portion 8b and the cap 16. The chamber formed by the above is used as a fixed amount chamber 14, and the push rod 13a (valve rod) of the valve 13 is moved by the iron core 12a of the solenoid 12 arranged below. As a result, the conventional fixed quantity plate open to the refrigerator was abolished, and the water discharged from the water supply bottle 8 immediately went to the ice making plate 24, so that the odor in the refrigerator compartment 2 melted into the water, In addition to eliminating the problem of the resulting ice smelling, it can also be a hygienic refrigerator.

(2) The sealing packing 22 is interposed at the contact portion between the constricted portion 8b of the water bottle 8 and the partition plate 15, so that the constricted portion 8b and the partition wall 8b can be separated from each other even if some dimensional error occurs in manufacturing the water bottle. Since the plate 15 can be completely sealed, the amount of water supplied to the ice tray 24 can always be set to a predetermined amount.

(3) The water purifier 20 (activated carbon for water purification and sterilization) is installed in the space formed by the partition plate 15 and the cover 17, and a small hole is provided in the partition plate 15 to supply water to the quantitative chamber 14. 15a is provided so that the purified water that has passed through the activated carbon portion and flows into the fixed quantity chamber 14 side can obtain sanitary and delicious ice.

(4) Since the tip of the push rod 13a of the valve is set in and out of the air vent pipe 21 which facilitates the replacement of water and air in the fixed quantity chamber 14, the pipe serves as a guide member for the valve rod. It is possible to prevent the pipe from being blocked by water due to surface tension or the like.

(5) When the push rod 13a (valve rod) is pushed up by the iron core 12a of the solenoid 12, the water pedestal 9 which plays a role of guiding the water which is opened by the valve 13 to the water supply conduit 11 is Since it is separated from the refrigerating compartment 2 by the cap 16 of the water bottle, the bacteria and dust in the refrigerating compartment will not enter the water receiving tray 9. Further, by doing so, it is not necessary to use the water bottle cover which is conventionally attached to the front surface of the water bottle, which is advantageous in terms of cost.

(6) Since the container 44 which is open in one direction and which constitutes the water supply bottle 8 and the lid 45 which covers this opening are formed by injection molding, it is advantageous in terms of cost.
Furthermore, the shape of the water supply bottle 8 can be easily formed by welding both.
