15 is fitted along the sleeve 18, and one ends of both rods 14, 15 are respectively fixed to the sleeve 18 of the right bottom plate 13, so that the left and right bottom plates 12, 13
The length can be adjusted. Left and right bottom plates 12, 13
A chute 253 is provided on each side of the rollers 23 and 25, and concave holes 254 are provided at intervals around the periphery of the chute, and convex points 252 that can fit in with the concave holes 254 are provided on the bottom surface of the bearing stand 10. , screw 25
5 can fix the bearing stand 10 (see Fig. 3).

Cylindrical container 4 with gear belts 42, 43 at both ends
1 is installed on the four rollers 22, 23, 24, 25, the gear belts 42, 43 can mesh with the outer body of each roller, and the belt 5 connects the two belt wheels 211, 222. Therefore, the rollers 22 and 24 operate to rotate the cylindrical container 41.

As shown in FIGS. 4 and 5, the scraper 61 is installed on the shaft 44 inside the cylindrical container 41, and plates 62 and 63 are provided at both ends of the scraper 61, and slots 642 are provided inside the plates 62 and 63, respectively. , 652 are formed in the hollow tubes 621, 631, and the two plates 62, 63 are also formed with slots 622, 632 (slot 622 is not shown in FIG. 5). A protrusion 641 is provided at both ends of the scraper plate 64, and the protrusion 641 can be fitted into the slots 622, 632.
Inside the hollow tube 621 is a stand rod 65 having a convex portion 651 that can be fitted into the slot 642 of the tube 621, and a spring 66 is provided on the rod 65 so that the stand rod 65 can pass through. The upper end of the tube 621 has a hollow part 6
23 is provided. The other hollow tube 68
There is also a hollow part 67 at the upper end, and upper and lower parts 681,
A stand rod divided into 682 parts is installed in the tube 68, and the two protrusions on the lower half part 682 can be fitted into the slots 652, and the lower end of the upper half part 681 and the upper end of the lower half part 682 have pins 683, respectively. 684
Then, springs 69 are installed within pins 683 and 684. The shaft 44 has a groove 45 into which the upper end of the upper half 681 of the upright rod can fit, and the connecting rod 611 is provided so as to maintain the space between the plates 62 and 63.

Shaft 44 of cylindrical container 41 shown in FIG.
A control rod 46 is provided vertically downward at the projecting end, and the safety device 7 shown in FIGS. 7, 8, and 9 includes a base plate 71, a control plate 72, and a flexible portion 73. etc., the base plate 71 on the left bottom plate 12 has a plurality of holes 711 arranged vertically, only the middle hole is formed in an oval shape, and the control plate 72 also has a plurality of holes 721 arranged vertically. A transverse rod 722 at the upper end of the control plate 72 intersects with the control rod 46, and a flexible portion 73 has two convex portions 73.
2 and a hole 731 is provided in the middle thereof, and one screw 8 is inserted into each middle hole 711 of these safety devices 7,
721, 731, and the two convex portions 732 of the flexible portion pass through the outer holes 711, 731.
Can be inserted into 721. Guide 74 has three surfaces and protects transverse rod 722 from counterclockwise rotation.

When the ice cream or the like in the cylindrical container 41 is sufficiently hardened, the scraper 61 is pushed by the hard ice cream or the like, and the control rod 46 of the shaft 44 starts operating, and at the same time the transverse rod 722 is also pushed and the Then, the protrusion 732 is separated from the hole 711 of the base plate 71 and the control plate 7
2 and the flexible portion 73 can rotate, and at this time, the transverse rod 722 does not intersect with the control rod 46, so the shaft 44 rotates together with the container 41, and the scraper 61 also stops scraping in the container 41. . Another safety device is that, as shown in FIGS. 6A to 6C, if the above-mentioned safety device fails, the scraper plate 64 is pushed by the ice cream or the like in the container 41 and rotates at a certain angle, and the scraper plate 64 rotates together with the container 41. Rotate to.

As shown in Figure 10, there is a switch 9 installed outside the refrigerator 9.
2 and a contact 91 are provided, and a flat electric wire is used as the power supply line 93, so that the cold air inside the refrigerator does not leak outside.

[Effect of the invention] Therefore, it is applicable to household refrigerators, and
A convenient ice cream making machine.
