Next, the frozen dessert manufacturing apparatus 1 configured as described above
The operation will be explained with reference to FIGS. 7 and 8.

First, the method of assembling the frozen dessert manufacturing apparatus 1 will be explained. With the mounting screw 14 loosened and the support column 3c of the support stand 3 inserted into the hollow part of the mounting part 27d, the container body 27 is moved upward. When operated, the claw portion 11a of the fixing ring 11 engages the support portion 3c.
is engaged with the engagement recess 3b. When the mounting screw 14 is tightened in this state, the elastic piece 11b is pressed by the shaft end of the mounting screw 14 and the pressing piece 13b of the pressing member 13, and the claw part 11a is inserted into the engagement recess 3b. engaged. As a result, a space is formed between the desk top surface and the lower surface of the maker main body 7, which is attached as will be described later, into which a plate for receiving manufactured frozen desserts, corn cups, etc. can be inserted.

In the above state, the engagement protrusion 21a provided on the case 9 of the drive unit 5 that has been moved upward is engaged with the engagement hole 29d, and the engagement protrusion 21b is engaged with the engagement groove 29f, so that the lid body 29 is attached to the drive section 5. Furthermore, the cold storage container 2 accommodated in the container body 27
Through hole 33d of cylinder 33 attached to 5
By engaging the engaging part 29a of the lid body 29 with the engaged part 27b while the upper part of the shaft part 31a of the rotating member 31, in which the screw 31b is rotatably supported, is inserted into the connecting shaft 15a. The manufacturing device main body 7 is attached to the lid body 29. The drive section 5 to which the manufacturing device main body 7 and the lid body 29 are attached is attached to the mounting section 27.
d, the engaging protrusion 27c and the engaging recess 23 are engaged with each other by rotating clockwise. This prevents the drive section 5 from rotating relative to the mounting section 27d. Note that when the rotary member 31 is rotatably supported within the cold storage container 25, the protrusion 61a of the feed screw 61 touches the cylinder 33.
is engaged with the claw portion 33e. In addition, the cold storage container 2
A holder 51 is attached to the lower end of the cylinder 33 attached to the hole 53 of the holder 51.
b is closed by a slide plate 53. Furthermore, the cold storage container 25 is cooled in advance in a freezing room,
The enclosed cold storage agent 32 is frozen to a required temperature.

In FIG. 7 showing the rotating state of the rotating member 31, when the electric motor 17 is driven in the above state, the rotating member 31 is rotated in the direction A of the solid line arrow shown in FIG. 7, and the feed screw 61 is rotated. As the member 31 rotates, it is rotated in the direction of the solid arrow B shown in FIG. When the prepared frozen dessert material is poured into the cool storage container 25 from the input opening 29c of the lid 29 in the above state, the frozen dessert material is cooled by adhering to the inner surface (inner peripheral surface and bottom surface) of the inner container 26. Ru. At this time, the frozen dessert material is adhered to the inner circumferential surface of the inner container 26 at a required thickness by the third blade 31f, thereby promoting the cooling effect, and the adhered frozen dessert material is scraped by the first blade 31d. be dropped. Further, the frozen dessert material attached to the bottom surface of the additional container 26 is removed from the second container 26.
It is scraped off by the blade 31e. Furthermore, the second blade 3
During the scraping action by the second blade 31e, since the uneven portion 31g is formed on the lower surface of the second blade 31e, it is possible to reduce the rotational resistance of the rotating member 31, and the second blade 31e can remove the frozen dessert. Materials are prevented from acting in a concentrated manner. The frozen dessert material gathered on the second blade 31e side by the above action is moved to the center by the feed screw 61 that advances toward the shaft portion 31a side, thereby causing convection within the cold storage container 25. As a result, the frozen dessert material is cooled while being stirred and kneaded almost uniformly.

After the frozen dessert material is kneaded while being cooled to the required hardness, the slide plate 53 is moved to form the hole 5.
3b and the through hole 51a of the holder 51 are brought into communication, the frozen dessert produced by the above action is gathered to the second blade 31e side by the scraping action by the first and second blades 31d and 31e. , is introduced into the cylinder 33 as the screw 31b rotates, and is discharged to the outside.

In FIG. 8 showing the downward movement state of the container body 27 with respect to the support stand 3, after the frozen dessert is manufactured as described above, the engaged portion 27b and the engaging portion 29a are moved by rotating the manufacturing device body 7. When the engagement is released, the manufacturing device main body 7 is removed from the lid body 29. When the engagement between the engagement protrusion 27c and the engagement recess 23 is released, the drive section 5 is removed from the attachment section 27d.
Furthermore, when the engagement between the engagement protrusion 21a and the engagement hole 29d and between the engagement protrusion 21b and the engagement groove 29f are released, the lid 29 is removed from the drive unit 5.

When the container body 27 is pushed downward after loosening the mounting screw 14, the engagement of the claw portion 11a with the engagement recess 3b is released due to the elastic deformation of the elastic piece 11b, as shown in FIG. After that, the support portion 3c is inserted into the center of the attachment portion 27d. As a result, the mounting position of the container body 27 with respect to the support stand 3 is lowered so that the storage volume is reduced.

In this way, in this embodiment, the engagement protrusion 21a is provided in the engagement hole 29d, and the engagement protrusion 21b is provided in the engagement groove 29f.
After the lid body 29 is attached to the drive part 5 by engaging the lid body 29, the cold storage container 25 with the rotating member 31 supported is accommodated in the engaging part 29a of the lid body 29, and is supported by the support stand 3. By engaging the engaged portion 27b of the container body 27, the support stand 3, drive portion 5, and manufacturer body 7 are integrated.
Then, by moving the maker main body 7 upward with respect to the support stand 3, a necessary space is formed between the lower surface of the maker main body 7 and the desk top surface into which a plate or cone, etc., for receiving the produced frozen dessert is fed. It is possible to do so. Further, by moving the maker main body 7 downward with respect to the support stand 3, it is possible to reduce the storage capacity of the frozen dessert manufacturing apparatus 1.

[Effects of the invention] Therefore, the present invention can provide an assembly structure for a frozen dessert manufacturing apparatus that allows each member constituting the apparatus to be easily assembled and that reduces the volume when stored. be.
