成されている。Below the first ice making chamber 11, a water tray 17 integrally provided with an ice making water tank 19 is pivotally supported by a pivot 16 so as to be capable of tilting and turning.
It is rotationally biased by an actuator (not shown). That is, as shown in FIGS. 3 (b) and 3 (c), when the second ice making chamber 11 pivotally supported by the first ice making chamber 11 is rotated clockwise.
When the first ice making small chamber 13 can be opened by 12 and is rotated in the counterclockwise direction, the second ice making chamber 13 is opened as shown in FIGS. 3 (d) and 3 (a).
The ice making chamber 12 is rotated to close the first ice making chamber 13.

Has been drilled. Then, as shown in FIG.
The water tray 17 is positioned horizontally and the second ice making chamber 12 is moved to the first ice making chamber 11
On the other hand, when closed, each of the fountain holes 18 corresponds to the through hole 12a formed in the second small ice making chamber 15. Further, as shown in FIG. 2 (b), a return hole 35 is formed with the fountain hole 18 in between, and the return hole 35 communicates with the ice making water tank 19 and the water tray 17 is closed. It faces the through hole 12a. Therefore, during the ice making operation described later, the ice making water was supplied to the ice forming spaces defined by the two ice making small chambers 13 and 15 through the fountain holes 18, and the ice making water was not frozen in the space. The frozen water is returned to the ice making water tank 19 through the return hole 35.

際して除氷水を不要とし得る。Here, both the support member 30 and the shaft 31 are made of a good heat conductor, and are set so that the heat conduction from the first ice making chamber 11 to the second ice making chamber 12 is good. That is, when the first ice making chamber 11 is cooled during the ice making operation, the temperature of the second ice making chamber 12 made of a good heat conductor becomes substantially the same as that of the first ice making chamber 11, and the spherical ice 34 is efficiently formed. Also,
When the first ice making chamber 11 is heated during the deicing operation, the second ice making chamber 12 is likewise heated, and the freezing of the spherical ice 34 with respect to the second ice making small chamber 15 can be released. In this case, deicing water may be unnecessary.

る。Operation of Embodiment Next, the actual use of the automatic ice maker according to the embodiment thus configured will be described. In the ice making operation state shown in FIG. 3 (a), each second ice making chamber 12 is horizontally positioned to close the first ice making chamber 11 from below, and the water tray 17 makes the second ice making chamber 12 from below. It's closed. At this time, the fountain holes 18 and the return holes 35 formed in the water tray 17 communicate with the through holes 12a of the corresponding second ice making small chamber 15, as shown in FIG. 2 (b).

される。When the ice making operation is started in this state, the ice making water pressure-fed to the distribution pipe 20 from the ice making water tank 19 via the pump 22,
The water is sprayed and supplied into the spherical space defined by the first small ice making chamber 13 and the second small ice making chamber 15 through the fountain hole 18 and the through hole 12a of the second small ice making chamber 15. Since both ice making compartments 13 and 15 are cooled by the refrigerant circulating in the evaporator 14, spherical ice is gradually formed in the space. The unfrozen water that has not frozen is collected in the tank 19 through the return hole 35 of the water tray 17, and is used for recirculation by the pump 22.

される。When the ice making operation is completed and the ice making operation is switched to, the actuator is driven at an appropriate timing, and the water tray 17 is urged to rotate in the clockwise direction. At this time, since the second ice making chamber 12 and the water tray 17 are only frozen by the ice blocks formed in the through holes 12a, the water tray 17 is forcibly peeled from the second ice making chamber 12.

氷小室15K内壁と球状氷34との氷結は依然維持される。Next, as shown in FIG. 3 (b), when the water tray 17 is tilted to the lowermost end, valve switching is performed in a refrigeration system (not shown),
Hot gas is supplied to the evaporator 14 provided in the first ice making chamber 11, and the first ice making chamber 11 is gradually heated. As a result, the freezing of the spherical ice 34 against the first ice making chamber 13 is released,
As shown in FIG. 6C, each second ice making chamber 12 is rotated clockwise by the weight of the spherical ice 34. However, the second ice making chamber 12 is also heated via the support member 30 and the shaft 31, but since the heating speed is slightly slower than that of the first ice making chamber 11, the inner wall of the second ice making small chamber 15K and the spherical shape are spherical. Freezing with Ice 34 is still maintained.

く、構造が簡単になる利点がある。When the freezing of the spherical ice 34 against the second ice making chamber 15 is released, as shown in FIG.
Is deviated in the opening direction of the second ice making chamber 15, the spherical ice 34 drops from the second ice making chamber 15 by its own weight. Since the surface of the water tray 17 waiting for tilting is flat, the spherical ice 34 settled on the surface of the water tray is smoothly slid and collected in an ice storage (not shown). That is, there is no need to separately provide an ice guide plate for smoothly guiding the spherical ice 34 to the ice storage, and there is an advantage that the structure is simple.

転を待機する。When all the ice cubes 34 have been collected in the ice storage and the deicing operation is completed, the actuator is reversely operated to return the water tray 17 to the horizontal posture and wait for the next ice making operation again. With the tilting of the water tray 17, as shown in FIG. 3 (d), the surfaces of the water tray 17 are hung from the first ice making chamber 11 to the respective second ice making chambers 12.
Then, the second ice making chamber 12 is gradually rotated counterclockwise about the shaft 31 to close the first ice making chamber 11 and wait for the next ice making operation.

等の付帯設備を不要とし得る利点もある。Effect of the Invention As described above, according to the automatic ice making machine of the present invention, the second ice making chamber is rotatably arranged on the lower surface of the first ice making chamber, so that each second ice making chamber of the second ice making chamber is rotated. The freezing of the spherical ice on the small chamber can be released by heat transfer from the first ice making chamber. That is, since deicing water is not required for deicing operation, it is possible to significantly reduce the amount of water consumed and reduce running costs. Moreover, there is an advantage that auxiliary equipment such as a tap water heating device can be eliminated.

る。Further, since the center of gravity of the ice blocks iced in the second ice making chamber is set to be offset to the outside of the opening end of the second ice making chamber, the ice blocks surely fall due to their own weight during the slow ice operation. Further, the ice blocks falling from the ice making chamber during the deicing operation slide down on the surface of the water tray that is standing by in a tilted state, and are smoothly collected in the ice storage. Therefore, it is possible to reduce the number of parts by eliminating the need for the ice guide plate, and to suppress the manufacturing cost.
