The present invention relates to a fixed quantity water supply device for an automatic ice maker for a refrigerator in an automatic ice making system installed in a refrigerator, so that only an appropriate amount of water can always be supplied to the automatic ice maker from the water supply apparatus installed in the refrigerator compartment.

According to the conventional water supply device, when the refrigerator is moved or the door is opened or closed, or when the lid of the water tank is loosely attached, the amount of water supplied from the water tank to the water supply tank exceeds the proper level. Since the water is supplied to the ice maker as it is, the water is excessively watered in the ice maker of the automatic ice maker, and the ice is not stuck to each other, as well as the ice. There were many problems such as poor phenomenon.

The present invention has been devised in consideration of these points, and by forming a double water separation wall installed in an intermediate position in the water supply tank and combining the filter in the space between these walls, the water flows out from the water tank and is contained in the supply chamber side. When the water passes through the water tank side of the water tank by the filter, foreign substances are filtered and the moving speed is controlled so that the water flows slowly. Also, at the top of the water tank side, there is a reservoir where water that exceeds the proper level in the water tank is stored. By installing and storing water that exceeds the proper level in the water supply chamber, the water supply system is operated so that the water in the water supply chamber is rapidly sucked and fed to the ice maker side. When the water supply operation of the water supply equipment is completed before entering the water supply chamber Eventually a suitable amount of water only will it be watering.

Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

Figure 1 shows the installation of the automatic ice making system, which is installed in the freezer compartment (A), the automatic ice maker (1) equipped with an ice maker (11) and an ice sensor (12) and ice storage for storing iced ice The container 2, the water supply device 3 and the water container 4 installed in the refrigerating chamber B, the water supply container 5 for receiving and storing water from the water container, and the water supply container 5 by the operation of the water supply device. It is composed of a water supply hose (3a) for allowing water to be rapidly raised from the water supply to the ice making container (11).

2 shows the installation and use state of the conventional water supply container 5 in the automatic ice making system configured as described above.

The water supply tank is provided with a water supply separation wall 51 at an internal intermediate position so that the interior is divided into a supply chamber 5a and a water supply chamber 5b, and a distribution port 51a is formed in the middle of the water supply separation wall 51. Thus, the water in the supply chamber 5a was moved to the water supply chamber 5b side.

In addition, the bottom of the supply chamber (5a) is projected to the appropriate height of the lid base 52 of the bucket to put the bucket 4 on the upper side is supported by the end of the bucket lid 41, the water in the bucket flows To come out.

On the other hand, the float switch 6 is installed on the side of the lid support 52 to the water tank support 7 so that when the water level in the water tank 5 reaches the proper level h, the float switch 6 detects this. Since the electric power is supplied to the water supply device 3 installed on the water supply chamber 5b to drive the pump motor 31, the impeller 32 is rotated to rapidly flow the water in the water supply chamber 5b through the suction port 33. The water was sucked into the ice-making container 11 on the freezing chamber A side through the water supply hose 3a.

However, since the conventional water supply container 5 merely serves to receive and store the water from the water container 4, the water supply container 5 may be caused by vibrations received during frequent opening and closing of the refrigerator door or movement of the refrigerator. When the lid 41 is not supported properly on the upper surface of the pedestal 52, or when the lid 41 is loosened, the amount of water from the bucket 4 exceeds the proper level h. More than that amount h 'will be contained in the sump (5).

In this case, the amount of water that is pumped up by the operation of the water supply device 3 and the water supplied to the ice making container 11 becomes the sum H of both the low water level (h) and the larger amount (h '). 11) There was a lot of problems, such as excessive water supply, water overflow, or ice cubes do not stick to each other, resulting in poor ice.

3 and 4 shows the installation use state of the subject innovation water supply container 5 designed to solve the problems of the conventional water supply container.

The water supply container 5 of the present invention has a double water supply separation wall 51, 51 'installed in the middle of the interior thereof, and a filter 53 is coupled to the space between these walls, and the separation wall 51 ( The flow rates of water moved from the supply chamber 5a side to the water supply chamber 5b side by means of the distribution port and the filter 53 are formed by vertically indenting the flow ports 51a and 51b at different sizes in the center of the 51 '). To slow down.

In addition, the upper side of the water supply chamber 5b is provided with a small diameter through-hole 81 on one side of the bottom surface so as to separately store the amount of water h 'exceeding the proper water level h. ) Stands through the inner surface of the catching jaw 83 and the water supply chamber 5b which speaks to the upper end of one side of the reservoir 8 installed through the through hole 82 through which the inner periphery of the penetrating hole is raised to an appropriate height. The bottom surface is coupled to the proper water level (h) by the piece 54 so that the amount of water h 'exceeding the proper water level h in the water supply chamber 5b is stored in the reservoir through the through hole 81. I went inside and contained it.

Therefore, when the amount of water flowing into the water supply container 5 exceeds the proper water level h, the amount h 'is stored in the storage container 8, so that the water supply device 3 is operated to operate in the water supply chamber 5b. When the existing water is rapidly pumped up to supply water, the moving speed of the water moving from the supply chamber 5a side to the water supply chamber 5b side is higher than that of the water supply speed 5a and 51b and the separation walls 51 and 51. ') Is slowed by the resistance of the filter (53) coupled between the'), and the water contained in the reservoir (8) falls through only the small diameter through-hole (81), and eventually the proper water level in the water supply chamber (5b) h) The water of the defective (h ') exceeding the proper level while the water corresponding to the water is introduced into the water supply chamber (5b) does not accumulate, so only the appropriate amount of water is always supplied to the ice making container (11).

As such, the present invention provides a double feedwater separation wall and at the same time combines a filter in the space therebetween to induce the movement speed of the water moving from the supply chamber to the feedwater chamber to be lowered. By installing reservoirs so that the water is stored separately, only an appropriate amount of water can be supplied to the ice making container at all times, and thus, there is an advantage that no de-icing or poor ice operation occurs in any case.

In addition, the filter filters out foreign matters, so that it is possible to provide clean ice at all times.
