Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a frozen dessert making machine, and particularly to a frozen dessert making machine in which containers, stirring gears, drive gears, etc. can be easily cleaned.

[Prior Art] In the past, various configurations have been proposed and adopted for this type of frozen dessert manufacturing machine, but a typical one is the structure disclosed in Japanese Patent Publication No. 59-33332. It has been known.

According to the structure described in the above publication, as shown in FIG. 3, the drive cover 01 has a substantially L-shaped cross section.
The bearing portion 02 formed at approximately the center of the
An intermediate shaft 04 having an intermediate gear 03 is rotatably supported, and this intermediate gear 03 has a drive cover 01.
A drive gear 06 of a drive motor 05 housed within is engaged.

A cylindrical bearing part 07 is formed at the lower part of the drive cover 01 and hangs integrally with the lower part, and a shaft part 09 is rotatably supported by the bearing part 07. The lower end of the shaft portion 09 extends into the container 011,
A stirring blade 08 is integrally formed therein, and the upper end thereof extends into the drive cover 01 and is fitted into a stirring gear 010 that meshes with the intermediate gear 03.

Furthermore, a lid 012 is provided to cover the open top of the cylindrical container 011. This lid body 01
2 is the outer periphery of the bearing part 07.

A conventional frozen dessert making machine is configured as described above and operates as follows.

That is, when the container 011 is filled with the stock solution and the drive motor 05 is rotated while cooling the stock solution through the container 011 by a refrigeration system (not shown), the driving force of the drive gear 06 drives the intermediate gear 03. The liquid is then transmitted to the stirring gear 010, the stirring blade 08 rotates, and the raw liquid in the container 011 becomes a frozen dessert such as ice cream.

[Problem to be solved by the invention] However, since the gears 03, 06, 010, etc. and the stirring blade 08, etc. are covered by separate members, that is, the drive cover 01 and the lid body 012, it is difficult to produce frozen products. After that, when cleaning, gear 03,
For 06 and 010, etc., remove the drive cover 01 from the container 011 and disassemble the drive cover 01, and then remove the drive cover 01. For the stirring blade 08 and container 011, after removing the drive cover 01, remove the lid body 012 from the container 011. The work had to be done by removing it from the body, making the work extremely troublesome. Furthermore, if the device is covered with a separate member as described above, the number of parts will inevitably increase, resulting in a larger device and an increase in manufacturing costs.

Therefore, an object of the present invention is to provide a compact frozen dessert making machine that is easy to clean and can be manufactured at low cost.

[Means for Solving the Problem] In order to achieve this object, the frozen dessert manufacturing machine according to the present invention has an annular receiving seat at the top, and defines a container storage space with an open top through the receiving seat. a main body case having a cooling tank for cooling, a lid body covering the receiving seat, a cylindrical container removably disposed within the container storage space, and a cylindrical container located within the main body case and penetrating the receiving seat. and a stirring device that is removably located within the container and has a shaft that extends upward.

A drive gear and a stirring gear that mesh with each other are removably connected to the upper end portions of the drive shaft of the drive motor and the shaft portion of the stirring device, respectively, so as to be positioned within the receiving seat. The drive gear and the stirring gear, which were attached to the drive gear, are also covered by the lid.

[Function] During cleaning, when the lid covering the receiving seat is removed, the driving gear and stirring gear are immediately exposed. These driving gears and stirring gears are removable,
Can be easily removed from the drive shaft and shaft.

Moreover, if the stirring gear is removed, or the stirring blade can be taken out together with the stirring gear, the container containing the frozen dessert is immediately exposed.

[Embodiment] Next, a preferred embodiment of the present invention will be described in detail with reference to FIGS. 1 and 2, in which the same reference numerals indicate the same or corresponding parts.

1 and 2 are partially detailed cross-sectional and partially schematic views of the frozen dessert making machine according to the present invention. A driving gear 6 and a stirring gear 10 are rotatably and removably disposed on the receiving seat 13 in a mutually engaged state. A lid body 16 having a knob 15 is placed on the receiving seat 13 so as to cover the driving gear 6 and stirring gear 10 from above.

The shaft hole 6a of the drive gear 6 is provided with the main body case 1.
A drive shaft 14 of a drive motor 5 attached to the lower surface of the receiving seat 13 is fitted inside. Also,
A shaft portion 9 having an integral stirring blade (stirring device) 8 at its lower end is fitted into the shaft hole 17 of the stirring gear 10 . The upper ends of these drive shafts 14 and shaft portions 9 are
As shown in FIG. 2, it is formed in the shape of a square prism, and the shaft holes 6a and 17 of the driving gear 6 and the stirring gear 10 that receive the upper end of the same have a shape that substantially matches the outer shape of the square prism. The drive gear 6 and stirring gear 10 are configured to be removably fitted to the drive shaft 14 and the shaft portion 9, respectively.

A substantially circular opening 18 formed offset from the center of the annular receiving seat 13 extends downward a predetermined distance, and then curves radially inward at an angle of 90 degrees,
Cooling tank 21 defining a cylindrical container storage space
is formed. A cooling pipe 19 of a refrigeration system 25 is wound around the cooling tank 21, and a heat insulating material 20 covers the outside thereof. In addition to this cooling pipe 19, the refrigeration system 25 includes a compressor 22 and a condenser 23.
and a capillary reach tube 24, and connecting tubes 26 and 27 connect these devices to form a closed loop.

Inside the cooling tank 21 is a container 1 with an open top.
1 is removably disposed, and a concave bearing part 28 is formed at the center of the bottom of the container 11, which also has the function of positioning the shaft part 9 described above. The bearing part 28 is
The lower end 9a of the shaft portion 9 is rotatably supported. Note that the bearing portion 28 may have a convex shape instead of a concave shape, and the lower end 9a of the shaft portion 9 may have a concave shape.

In the frozen dessert manufacturing machine having the above configuration, when manufacturing frozen desserts, the lid 16 is first lifted and removed from the main body case 1, and the lid 16 is inserted into the container 11 through the supply hole 10a formed in the drive gear 10. supplies liquid frozen dessert ingredients to Thereafter, preferably after closing the lid 16, the freezing system 25 is driven to cool the frozen dessert raw material, and the drive motor 5 is energized to rotate the stirring blade 8 to stir the frozen dessert raw material.

After a predetermined period of time, a portion of the frozen dessert raw material begins to freeze in a layer on the inner wall of the container 11, and this frozen layer is scraped off by the cutting edge of the stirring blade 8 and accumulates at the bottom of the container. By repeating this process, the entire frozen dessert raw material in the container 11 is frozen into the shape of ice cream or a syrup, and the frozen dessert is completed.

After the production of frozen desserts is completed, to collect the frozen desserts in the container 11, simply remove the lid 16 and then lift the stirring gear 10 and the stirring blades 8 upward, and the preparation for collection is completed. Note that in this state, the container 11
is exposed, so the container 11 is placed in the cooling tank 21.
You may take it out and collect the frozen dessert.

Next, when cleaning is performed, as described above, the stirring gear 10, stirring blades 2, and container 11 are attached to the main body case 1.
Since the drive gear 6 has already been removed from the drive shaft 14, it can be easily disassembled by removing only the remaining drive gear 6 from the drive shaft 14, and the aforementioned parts can be easily cleaned.

[Effects of the invention] As described above, in the frozen dessert making machine of the invention, when only the lid covering the tray is removed during cleaning, the driving gear and stirring gear are immediately exposed, and these driving gears and stirring gears are exposed. Since the stirring gear is removable and can be easily removed from the drive shaft and shaft, the stirring blades can be taken out by removing the stirring gear or together with the stirring gear, and then the container containing the frozen dessert can be removed. Since it is exposed immediately, various effects such as the following can be obtained.

(1) With only a simple disassembly operation, cleaning work of the drive gear, stirring gear, stirring blade, container, etc. can be performed quickly and easily without any hindrance.

(2) Since the so-called cover is only the lid body and two gears are used, the number of parts is reduced and a compact frozen dessert making machine can be manufactured at low cost.

(3) Since the cover is only the lid body, the unevenness of the entire device is reduced, and it is possible to provide a frozen dessert making machine with an extremely excellent appearance.
