Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention includes a cylindrical container with a bottom that accommodates a material to be processed, and a container that is placed upright within the container to agitate, cut, crush, etc. the material to be processed. The present invention relates to a processing device including a rotating member for processing.

[Prior art]

Examples of this type of processing equipment include ice cream, freezing equipment for ice production, and various other equipment such as mixers, juicers, meat choppers, etc., and the container is assembled in a casing and placed on the upper periphery of the casing. It is covered with a removably assembled lid.

[Problem that the invention attempts to solve]

By the way, in such a device, high accuracy is required for the distance between the inner wall of the container and the rotating member, and if the above-mentioned distance is not accurate, there is a risk that the outer edge of the rotating member may slide against the inner wall of the container, causing interference. . Therefore, when installing the rotating member upright, it is necessary to minimize assembly errors. In addition, a driven gear is assembled horizontally to the rotating shaft of the rotating member that stands up as a drive mechanism for the rotating member, a drive motor is parallel to the rotating shaft, and a driven gear is assembled horizontally to the rotating shaft of the motor. When using a drive gear that meshes with the drive gear, it is necessary to ensure the parallelism of the rotating shafts of both the rotating member and the motor, and the horizontality of both gears, which will prevent interference between the rotating member and the container. Problems in the meshing state of both gears, the occurrence of abnormal noises caused by these problems, radial rocking of each gear, etc. are eliminated.

Therefore, an object of the present invention is to ensure the parallelism of both rotating shafts and the horizontality of both gears by erecting the rotating member with high precision.

[Means for solving problems]

In order to achieve this object, the present invention fixes the containers of the various devices described above at their upper end peripheral edges to the upper opening peripheral edge of the casing, and rotates the lower end side of the rotary member at the bottom of the container. The feature lies in that the upper end side of the rotary member is rotatably supported on the lower surface of the lid body.

[Operations and effects of the invention] In this configuration, since the container and the lid function as bearings that support both the upper and lower ends of the rotating member, and both are attached to the same casing, the rotating member cannot be placed upright. The assembly error with respect to the container and the lid is extremely small, and the parallelism of both the rotation axes of the motor and the rotating member and the horizontality of both gears can be ensured sufficiently. This may cause interference between the rotating member and the container, problems with the meshing status of both gears,
The occurrence of abnormal noise, radial rocking of each gear, etc. caused by these are eliminated.

The ice-making holding frame 12 has a shape formed by dividing a cylindrical frame body having a predetermined width in the radial direction into three parts in the same direction, and is composed of three frame elements 12a. Inside each frame element 12a, a large number of cubic-shaped holding chambers 12b are formed that expand radially toward the outer periphery. In this holding frame 12, each element 12a forms a cylindrical frame within the cooling tank 11, and is formed in a size that allows each element to be taken out independently. In addition, each element 12a
A grip portion 12c for attaching and detaching is protruded from the uppermost horizontal partition plate portion of the holder. The impeller 13 for ice making has two blades 13 on the outer periphery of a rotating shaft 13a.
b, 13c are integrally formed in two stages, upper and lower, and a cylindrical protrusion 13d that fits into the through hole 11a of the cooling tank 11 is formed at the lower end of the rotating shaft 13a. Further, a prismatic protrusion 13e is formed at the upper end of the rotating shaft 13a, and the protrusion 13e is fitted into a recess of a large diameter gear of a drive mechanism 20, which will be described later. The impeller 13 is positioned and rotatable within the ice holding frame 12 with the protrusion 13d fitted in the through hole 11a of the cooling tank 11 and the protrusion 13e fitted in the recess of the large diameter gear. In such a state, the first
As shown in the figure, the outer edge of each blade 13b, 13c faces the inner periphery of the holding frame 12 in close proximity.

The reference numeral 38 is a lid that covers the upper end of the casing 34, and the lid 38 is removably fitted to the upper peripheral edge of the casing 34 as shown in FIG. As shown in the figure, the central protrusion 23c of the large diameter gear 23 is located in the recess 38a.
The gear 23 is fitted to rotatably support the gear 23. Therefore, the lid body 38 functions as a bearing for the impeller 13 and the large diameter gear 23 together with the cooling tank 11.

In order to produce ice using the freezing device, first, the drain hose 37c is fitted to the holder, and then the cooling tank 11 is
Either by injecting a predetermined amount of water into the cooling tank 11 and placing and assembling the holding frame 12 and impeller 13, or by placing both 12 and 13 in the cooling tank 11 and assembling them, then pouring the above amount of water into the cooling tank 11. It is injected through an opening (not shown) of the large-diameter gear 23. The holding frame 12 is assembled by arranging the frame elements 12a constituting these in a cylindrical shape in the cooling tank 11, and the impeller 13 is assembled to the large diameter gear 23, and the impeller 13 in this state is assembled into the holding frame. It will be installed within 12. The impeller 13 is assembled by fitting the protrusion 13d of the rotating shaft 13a into the through hole 11a of the cooling tank 11, thereby fitting the holding frame 12 and then the small diameter gear 22 of the drive mechanism 20 to the adapter 21b of the motor 21. At the same time, the recess 23 of the large diameter gear 23
The impeller 13 is assembled to the large-diameter gear 23 by fitting the protrusion 13e of the impeller 13 into the portion a, and is positioned and rotatably supported within the holding frame 12. Finally, the lid 3 is attached to the upper edge of the casing 34.
8, the refrigeration system is set to the state shown in FIG.

In such a state, if the switch of the drive circuit (not shown) of the refrigeration system is closed and electricity is supplied for a predetermined period of time, the compressor 31, condenser 32, etc. will start, and the cooling medium will flow from pipe 35b to 35a shown in FIG. →３
5d to cool the cooling tank 11, while the motor 21 in the drive mechanism 20 is started to rotate the impeller 13 and stir the water. However,
As cooling progresses in the cooling tank 11, the holding frame 12
The holding chamber 12b of each frame element 12a constituting the
Transparent ice grows inside the cooling tank 11 from the outer circumferential side, and after a predetermined period of time, all the water in the cooling tank 11 turns into ice and reaches the inner circumferential side of each holding chamber 12b. At this point, the motor 21 is de-energized, and the on-off valve 36c is energized for a short time. As a result, the on-off valve 36c is opened, and the cooling medium flows back through the pipes 35b, 35c, and 35d shown in FIG. 2 in this order. Since the cooling medium in this state is in a hot gas state, the portion of the ice cubes in the holding chamber 12b of each frame element 12a that comes into contact with the inner periphery of the cooling tank 11 melts, and the portion of the ice cube in the holding chamber 12b of each frame element 12a that contacts the inner circumference of the cooling tank 11 melts, thereby bonding each frame element 12a to the cooling tank 11. is solved. After that, the supply of electric power to the refrigeration system is stopped, and the compressor 31 stops driving. Therefore, by removing the lid 38 and taking out the impeller 13 together with the large-diameter gear 23 from the cooling tank 11, each frame element 12a holding a large number of ice cubes can be easily taken out. Note that by twisting both ends of the removed frame element 12a in opposite directions, the ice cubes in each holding chamber 12b can be easily removed. Moreover, the frame element 12a holding ice cubes can also be stored in a freezer.

In this way, in the refrigeration system, the impeller 13 and the large diameter gear 23 are connected to the cooling tank 11 and the lid 3.
8, and since both 11 and 38 are attached to the same casing 34, the impeller 13 and the large diameter gear 23
The assembly error for the cooling tank 11 and the lid 38 is extremely small. In addition, the upper plate 34 of the casing 34
