Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an ice making machine of a refrigerator, and more specifically, relates to a water supply device in a mechanism for simultaneously driving two ice trays.
[0002]
[Prior art]
A conventional automatic ice maker for a refrigerator having a plurality of ice trays includes a means having a water supply path branched into a plurality of paths, a means having a water supply path branched into a path corresponding to each of the plurality of ice trays, and a water supply pipe Various water supply means such as a means having a plurality of water supply ports, a means for forming a throttle at a branch portion of a water supply path branched into a plurality of paths, and a means for providing a plurality of water supply pipes in an ice tray are used.
[0003]
[Problems to be solved by the invention]
However, the means for providing a water supply path branched into a path corresponding to each of the plurality of ice trays and the means for providing a plurality of water supply pipes on the ice tray differ in the amount of water after branching and supply equal water to the ice trays. Difficult to do. Among the above-mentioned means, the means for forming a restriction at the branch portion of the water supply path branched into a plurality of paths can evenly distribute the amount of water if the pump water pressure is large.
[0004]
However, the problems here are: (1) A large pumping capacity is required to uniformly apply water pressure to a plurality of throttle parts. (2) The load of the motor that drives the pump during water supply to throttle the water flow. (3) Since the water pressure is large, airtightness and strength that can withstand water leakage at the joint portion of the path from the pump to the throttle portion are necessary.
[0005]
Accordingly, an object of the present invention is to evenly distribute water to ice trays without increasing the size of the pump and without increasing the burden on the water supply path.
[0006]
[Means for Solving the Problems]
In order to achieve the above object, the water supply mechanism of the automatic ice making machine according to the present invention drops the ice at the deicing position obtained by inverting the ice making tray from the ice making position for producing ice, and then the ice making tray is moved to the ice making tray. In the water supply mechanism of an automatic ice maker that returns water to the position and sequentially produces ice, a water storage tank for storing water to be supplied to the ice tray, a suction port for sucking water from the water storage tank, and the water sucked into the ice tray A flowing water path having a discharge port for discharging, and a pump that is disposed in the middle of the flowing water path and sucks water from the suction port and discharges it into the water storage chamber before discharging it to the ice tray, wherein the water flow path, after the water in the water flow path is through the pump, once one of the water storage chamber to be accumulated prior to discharge to the ice tray provided, on the bottom of the one of the water storage chamber, the double Extending towards the two ice trays It was bored only two coupling holes of the respective communicating with two flow paths, the coupling hole of the both take the same water pressure opening effective area of both forms of the same area provided aperture together Thus, the same flow rate of water is simultaneously supplied to the two ice trays by only one flow path, and the water storage chamber is provided with a vent for guiding the air in the water flow path to the outside. It is provided.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an embodiment of a water supply mechanism of an automatic ice making machine according to the present invention will be described with reference to the drawings. FIG. 1 is a schematic diagram for explaining an embodiment of a water supply apparatus 10 in a water supply mechanism of an automatic ice making machine according to the present invention.
[0008]
A plurality of ice trays 12-1 and 12-2, which have completed ice making, are solidified by turning them in the directions of arrows K1 and K2 around a rotation shaft 14 as shown by a two-dot chain line by a drive source (not shown). The ice removal operation 16 of the ice block 20 is performed, and the ice block 20 which has been deiced is stored in an ice storage tank 18 provided below the ice trays 12-1 and 12-2. The ice trays 12-1 and 12-2 after deicing are returned to a horizontal position as indicated by a solid line, and a water supply operation is performed by the water supply device 10.
[0009]
The water supply apparatus 10 is provided with a water storage tank 24 and injects and stores a required amount of water suitable for ice making from an appropriate water source by an appropriate means. Before the water 30 in the water storage tank 24 is sucked from the suction port 32 and discharged from the discharge ports 34-1 and 34-2 respectively corresponding to the ice trays 12-1 and 12-2, the water storage tank 38 is temporarily filled. A pump 22 for discharging is provided. A constant capacity transfer type centrifugal pump or a gear pump is used as the pump 22, and a fixed amount of water is transferred to the water storage chamber 38 by being controlled using a timer or the like.
[0010]
In a flowing water path 36 that connects the suction port 32 to the discharge ports 34-1 and 34-2, a water storage chamber 38 is disposed on the downstream side of the pump 22 and upstream of the discharge ports 34-1 and 34-2. The water poured into 12-1 and 12-2 is temporarily stored before discharging. Two connecting holes 44-1 and 44-2 communicating with two flow paths 42-1 and 42-2 corresponding to the two ice trays 12-1 and 12-2 are formed in the bottom 40 of the water storage chamber 38. Is done.
[0011]
The two connecting holes 44-1 and 44-2 are respectively provided with a throttle 45 so that the opening effective areas of both are made the same, and the water in the water storage chamber 38 flows down by the natural water column head pressure. -1 and 12-2 are adjusted so that they are supplied within the same time set at the same flow rate.
[0012]
As mentioned above, although one Example of the water supply mechanism of the automatic ice making apparatus concerning this invention was described based on drawing, this invention is not limited to the Example of illustration, About the shape, a structure, etc. of this invention, It is expected that various changes in details and modifications such as reconfiguration of parts can be made without departing from the configuration requirements.
[0013]
【The invention's effect】
As apparent from the above description, according to the water supply mechanism of the automatic ice maker according to the first aspect of the present invention, the ice is dropped at the deicing position where the ice tray is inverted from the ice making position where the ice is produced. Then, in the water supply mechanism of the automatic ice maker that returns the ice tray to the ice making position and supplies water, and sequentially manufactures ice, a water storage tank for storing water to be supplied to the ice tray, and a suction port for sucking water in the water storage tank; , and water path and a discharge port for discharging the sucked water to the ice tray is disposed in the middle of the water flow path, once reservoir chamber prior to discharge to the ice tray sucking water from the suction port and a pump for discharging, to the said water flow path, the water flow path after the water has traversed the pump, provided with the water storage chamber of one to be accumulated temporarily before ejecting the ice tray, this one At the bottom of the water reservoir, two Towards ice dish drilled coupling hole only two of each communicating with two flow paths that extend, in the coupling hole of the both, the same area of opening effective area both provided aperture together And the same water pressure is applied to the two ice trays so that the same flow rate of water is simultaneously supplied by only one flow path to each of the two ice trays. By providing a vent for guiding the air to the outside, high quality and homogeneous ice blocks can be automatically mass-produced at one time. In particular, the water storage chamber has an air vent that guides the air in the water flow path to the outside, so that the water accumulated in the water chamber by a constant urging force based on atmospheric pressure and gravity is used instead of water pressure by a pump. A uniform water pressure can be applied to the throttle portion. For this reason, it is not necessary to consider the load applied to the pump drive motor and the airtightness of the water channel, and it is possible to cope with the water supply technology of one flow channel.
