Next, the operation of the present invention will be described based on the above configuration.
When the ice making process is started in a horizontal state in which the water tray (5) closes the opening surface of the ice making chamber (1A), the circulation pump (10) operates to discharge the ice making water in the water tank (6) to the discharge pipe (1).
1) through the ice making water inlet (12) to the ice making water canal (25)
Enter the main water channel (25A) and then the branch water channel (25B) to the fountain hole (15) for ice making and supply the fountain to the ice making chamber (1A).
A part of this ice making water is frozen in the ice making chamber (1A), and the unfrozen water returns from the return hole (16) to the water tank (6) through the return passage (27). (This flow of water is shown in Figs. 1 and 6
(Indicated by the solid arrow in the figure).

In this way, the ice making water in the water tank (6) is stored in the ice making chamber (1
When a predetermined amount of ice has grown in the ice making chamber (1A) by circulating to A), or when an ice making completion detecting means such as a thermostat detects it, the circulation pump (10) is stopped to complete the ice making. To do.

When ice making is completed, the water supply solenoid valve (7) is opened and the water supplied from the water supply pipe (8) is passed through the deicing canal (26) as shown by the dotted arrows in FIGS. 1 and 6. After that, the fountain is supplied from the cleaning fountain hole (17) to the surface of the upper plate (18).

In this way, when water is passed from the external water supply system to the deicing canal (26), the sensible heat of the water is transmitted to the ice side through the top plate (18), and as shown in FIG. ) Melt the lower surface of the ice (34) frozen and adhered to the upper surface plate (18) and ice (34).
Since the adhesive force between the upper plate (18) and the ice (34) can be expected to be separated due to the expansion of the upper plate (18) due to the temperature rise, the drive device is completed based on the completion of the ice making. (4) is activated, and the bottom surface of the ice (34) moves to the top plate (1
When peeling off 8), the load applied to the drive device (4) can be made almost unloaded. Thus, when the water tray (5) is fully opened by the drive device (4), the drive device (4) is stopped and the water supply solenoid valve (7) is also closed to allow water to flow to the deicing water channel (26). Stop.

By the way, the water that has been supplied to the surface of the upper surface plate (18) from the cleaning fountain hole (17) after flowing through the ice removing water channel (26) flows down the surface of the tilting upper surface plate (18). At this time,
After cleaning the surface of the top plate (18) and once collecting it from the lower edge of the top plate (18) into the water tank (6), the drain tray from the drain port (32) through the drain guide plate (33). Be drained to.

It is desirable that the operation of the drive device (4) be slightly delayed from the opening of the water supply solenoid valve (7), but the drive device (4)
Since there is a mechanical delay from the operation of (1) to the start of tilting of the water tray (5), electrically opening the water supply solenoid valve (7) and operating the drive unit (4) may be performed simultaneously. The experimental results were obtained.

On the other hand, the ice frozen in the ice making chamber (1A) is slightly melted by the heat of the hot gas circulated in the evaporation pipe (2) when the ice making is completed, and then the ice is separated from the ice making chamber (1A) and the ice making chamber (1A)
The upper plate (18) of the opened water tray (5) slides down and is guided to an ice storage (not shown).

Then, when it is detected that the ice has separated from the ice making chamber (1A) by the temperature rise of the cooler (1), the drive device (4) is activated again to move the water tray (5) back. At the same time, the water supply solenoid valve (7) is opened to pass through the same route as described above, that is, the deicing water channel (26) to the cleaning fountain hole (17) to the top plate (1
The water supplied to the surface of 8) is supplied to the water tank (6) as ice making water for the next cycle from the return hole (16) and the lower edge of the top plate (18). When the water tray (5) returns to the horizontal position where it closes the opening surface of the ice making chamber (1A), the drive device (4) is stopped, and then a predetermined amount of ice making water is supplied to the water tank (6). Then, the water supply solenoid valve (7) is closed to stop the water supply operation. When the water supply operation is stopped, the water in the deicing canal (26) is entirely supplied from the drain port (31) to the water tank (6), so that water may remain in the deicing canal (26). Absent.

As another embodiment of the present invention, an adhesive is applied to the edge of the partition wall (28) of the lower main body (14), and the upper main body (13) is attached.
It may be fitted in the groove (21).
