Description

[Detailed description of the invention] This invention relates to an ice cream maker that makes ice cream by stirring cream ingredients in a freezing atmosphere such as the freezer compartment of a refrigerator. To provide an extremely practical ice cream maker which can automatically stop its operation and thereby reliably prevent melting of finished ice cream and wasteful power consumption.

An embodiment of the present invention will be described below with reference to the drawings. First, in FIG. In detail, as shown in FIG. 2, there is a reduction gear mechanism 6 comprising a worm 3 attached to a shaft 2a, a worm wheel 4 meshing with the worm 3, and a gear 5 meshing with a so-called small gear portion 4a of the worm wheel 4. The gear shaft 5a is received by the bearing cylinder part 7 in the upper part of the main body case 1 and the bearing hole part 8 in the lower part thereof, and the gear 5 in the final stage is held so as to be movable up and down. This gear shaft 5a
For this reason, a compression coil spring 9 is housed in the bearing cylinder 7, so that the gear 5 is always resiliently biased downward together with the gear shaft 5a.

Reference numeral 10 denotes a switch operation section protruding in an annular shape from the bottom of the gear 5, and this is electrically connected to switch the energization of the motor 2 and an indicator, such as a lamp 11, as shown in FIG. A drive side 14 of a slip clutch 13 having, for example, an inclined surface 14a on the lower surface is attached to the protruding lower end of the gear shaft 5a.

On the other hand, 15 is a creaming container, and 16 is its lid, which is inserted into the lid 16 from below to above through a bush 18 such as a shaft 17a of a W pusher 17, and its protruding upper end. For example, a driven side 19 having an inclined surface 19a on the upper surface of the slip clutch 13 is attached to the slip clutch 13.

Now, in the case of this embodiment configured as described above, when producing ice cream, first a cream material (not shown) is placed in the creaming container 15, then the stirring blade 17 is placed in the container without the lid 16, and then the entire container is placed in the container 15 without the lid 16. is placed below the main body case 1 which has been placed in a freezing atmosphere such as a freezer compartment of a refrigerator, and the slanted surface 1 of the driven side 19 of the slip clutch 13 is
9a against the slanted surface 14a of the drive side 14.

On the other hand, on the open main body case 1 side, the gear 5, which is urged downward by the elastic force of the compression coil spring 9, moves the switch operation part 10 as shown in the lower part of FIG. As shown in the position, the gear 5 is shifted from the limit switch 12, but when the driven side 19 of the slip clutch 13 is brought into contact with the drive side 14 as described above, the gear 5 is pushed up together with its gear shaft 5a. The switch operation part 10 is aligned with the limit switch 12 and the switch 1 is
2, the motor 2 is energized and started in the state shown by the two-dot chain line in FIG.

When the motor 2 is started in this manner, its rotational power is transmitted from the reduction gear mechanism 6 to the stirring blade 17 in the creaming container 15 via the clutch clutch 13. rotates and stirs the cream ingredients.

Therefore, from then on, the stirring is continued in the frozen atmosphere, so that ice cream is gradually formed.Once the ice cream is finished, the cream material solidifies, and the load on the stirring blades 17 increases, causing them to stop rotating.

Then, the driving side 14 of the slip clutch 13, which continues to rotate in response to the rotational power of the motor 2, slips with respect to the driven side 19, which has stopped together with the stirring blades 17, and the respective inclined surfaces 14. 19a, and the gear 5 is also displaced upward together with its driving side 14. This displacement causes the switch operation part 10 to move away from the limit switch 12 to the upper two positions in the figure. Since the switch 12 is shifted to the position shown by the dotted chain line and the switch 12 is returned to the state shown by the solid line in FIG. 3, the Q current to the motor 2 is cut off.

In this way, in the case of this embodiment, since it is possible to prevent the motor 2 from overheating after the ice cream is finished and to automatically prevent it from overheating, it is also possible to reliably prevent the ice cream from melting after the ice cream is finished. Furthermore, it is possible to prevent wasteful energization of the motor 2 after the motor 2 is completed, and to achieve a sufficient power saving.

In particular, in the case of this embodiment, as described above, after the ice cream is completed, the power to the motor 2 is automatically cut off, and at the same time, the limit switch 12 is switched to turn on the lamp 11, which is an indicator. This makes it possible to display what is called a finished product, making it even more convenient in practice.

However, the present invention is not limited to the embodiments described above and shown in the drawings, and therefore, there may be changes in the presence or absence of indicators such as lamps, the specific structure of the slip clutch, the method of stirring the cream ingredients, etc. Next, you can change the tomb as appropriate without departing from the gist of the project.

In summary, the present invention is an ice cream maker that stirs cream ingredients by transmitting the power of a motor to stirring blades in a creaming container placed in a freezing atmosphere. A clutch is provided in the middle of the system to prevent the driving side from displacing away from the driven side as the ice cream is completed, causing slippage with respect to the driven side, and the clutch responds to the displacement of the driving side of this clutch. It is characterized by a limit switch that cuts off the power to the motor when the ice cream is pulled, and prevents the motor from locking after the ice cream is finished, and in particular prevents the ice cream from locking due to overheating of the lock. This has excellent practical effects in that it can reliably prevent the melting of the liquid and also reliably prevent the wasteful consumption of electric power.
