排水皿46から離れた反転姿勢にある。In this configuration, when the water supply tank 18 filled with water is set at a predetermined position by the user, the valve 2o is pushed up, the water supply port 19 is opened, and the water storage tray 21 is filled with water. After that, the filled water is transferred to the water supply pump 22
The water is pumped up and water starts being supplied to the ice tray 33 via the water supply pipe 58. When water is supplied to one of the small sections 34 of the ice tray 33, a predetermined amount of water is supplied into the other small sections 34 through the communication groove 36.
2). This state is shown in FIG. 3, where the draining tray 37 is in an inverted position away from the draining tray 46.

外周からの冷却作用も抑えられ、凍結作用は製氷皿33
の上方から下方へ向けての一方向に進行していく。In this state, the cold air cooled by the cooler 8 is forced through the ventilation path 69 onto the ice coating surface of the ice making tray 33 by the air blower @9, and the cooling action is started. At the same time, the heating action of the heater 32 disposed on the bottom of the heat insulating tank 28 is started, and the metal plate 30 on the bottom is heated. Also, ice tray 33
Since the outer periphery of the ice tray 33 is surrounded by a heat insulating material 31 in the heat insulating tank 28, the cooling effect from the outer periphery is also suppressed, and the freezing effect is suppressed by the ice tray 33.
It progresses in one direction from above to below.

下した未凍結水が共存した状態となっている。For this reason, if the freezing rate is slowed down to an appropriate level (for example, about 6 fights/h), gas components dissolved in the water and various impurities contained in the water will be precipitated outside the ice crystals as ice forms, and the unfrozen water below will be deposited. Pressure is released into the water. In this way, the ice that is successively produced over time has very high transparency and becomes highly pure ice with few impurities. Then, as a predetermined cooling time elapses, ice of a required appropriate thickness (for example, 26 fl) is generated. In other words, as shown in FIG. 4, the state light shows a state in which highly transparent and pure ice coexists in the upper part of each small section 34 of the ice tray 33, and unfrozen water with reduced purity coexists in the lower part. It has become.

is stopped for a certain period of time. After this, the temperature of the drain tray 46 is raised sufficiently, and then the drive device 40 is activated to move the first support shaft 38
, the second support shaft 39 starts rotating, and the draining tray 39 is first reversed and set above the draining tray 46, then the ice tray 33 is rotated and removed from the insulation tank 28, and is set first. It is inverted to a position close to the draining plate 37 so as to overlap above it. At the same time, the heating action of the heater 32 in the heat insulating tank 28 stops. Then, the backing plate 44 fixed to the ice tray 33 comes into contact with the stopper 42 provided on the drive device 4o, and the drive device 40 applies rotational force to the ice tray 33 through the trench, thereby distorting and deforming the ice tray 33. Each small plot 3
The ice in the container 4 is released and falls onto a grid-shaped draining tray 37 set below. At the same time, unfrozen water with increased concentration of gaseous components and impurities remaining in each subdivision 34 also flows out and falls, but since the draining tray 37 is formed in a lattice shape and most of the through holes are occupied, Then, the ice does not accumulate on the draining tray 37, but instead falls into the draining tray 46, where the ice and water are separated. That is, only highly transparent and pure ice remains on the draining tray 37. This state is shown in FIG.

昇を図り排水皿を凍結防止することができる。In this way, before ice removal, the heater 48 of the drain tray 46 is energized for a certain period of time, and at the same time, the compressor 53 and the blower 9 are forcibly stopped, thereby raising the temperature of the drain tray 46 sufficiently and freezing the drain tray. It can be prevented.

て蒸発される。On the other hand, the unfrozen water that has fallen into the drain tray 46 is drained through the drain pipe 47 into the water guide pipe 67 and into the evaporator tray 66 of the evaporator 62 in the machine room 61. Thereafter, the water drained into the evaporating dish 66 is evaporated by the heating action of the heating plate 66 that is brought into close contact with the heating tube 64 through which the high-temperature, high-pressure refrigerant gas from the compressor 63 flows.

。In addition, the drain plate 46. In order to prevent the flowing water from freezing in the drain pipe 47, heaters 48 and 49 appropriately heat the drain pipe 47.

6が駆動装置4oに設けたストッパー43に当接する。On the other hand, since the ice thus left has moisture attached to a portion of its surface, it is cooled and dried as it is for a suitable period of time. Thereafter, as shown in FIG. 6, the drive device 40 operates again to rotate the first support shaft 38 degrees and the second support shaft 39, and first the ice tray 33 rotates and is placed in the heat insulating tank 28. On the other hand, the draining tray 37 is turned over from the top of the draining tray 46 and the backing plate 4 is fixed to the draining tray 37 above the ice storage box 50.
6 comes into contact with a stopper 43 provided on the drive device 4o.

貯氷箱60内に落下し貯氷される。この状態を第6図に
示す。Then, as the drive device 40 further applies rotational force to the draining tray 37, the draining tray 37 is distorted and deformed, and the ice placed on the draining tray 37 is released and placed in the ice storage box 60 provided below. falls and is stored as ice. This state is shown in FIG.
こうして、給水タンク18が使用者によってセットされ

一連の行程を自動的に繰り返す。In this way, after the water supply tank 18 is set by the user, these series of steps are automatically repeated until the water in the water supply tank 18 is used up.
