Description

[Detailed Description of the Invention] [Purpose of the Invention] (Field of Industrial Application) The present invention relates to an electric frozen dessert manufacturing machine for ice cream, sherbet, etc., which is mainly used at home.

(Conventional technology) Conventionally, electric frozen dessert making machines for home use include:
For example, as shown in Japanese Utility Model Application Publication No. 59-172589, a device is known that includes a container unit and a drive unit disposed adjacent to the container unit. The container unit includes a cold storage container provided in an outer case with an open top, a lid provided in the top opening of the outer case, a stirrer provided in the cool storage container, and a rotating shaft of the stirrer. The upper part of the drive unit projects above the lid body to mount the driven side clutch, and the drive unit forms a projecting part disposed on the case,
A drive pulley connected to the motor is provided on the projecting portion, and a drive-side clutch connected to the driven-side clutch of the stirring body is attached to the drive pulley.

And when making ice cream etc.
After storing the cold storage container in the outer case and closing the lid, connect the clutch of the drive unit to the clutch of the agitator. If you want to take out the finished ice cream, etc., lift the drive unit and close the clutch. The connection is removed and the container unit is taken out.

(Problems to be solved by the invention) According to the above structure, when engaging and disengaging the clutch, it is necessary to lift the entire drive unit. In other words, the relatively heavy drive unit containing the motor etc. must be lifted. It is difficult to use because the clutch is engaged and disengaged.

The object of the present invention is to improve usability by making it possible to easily engage and disengage the stirring body of the container unit from the drive unit side without lifting the heavy drive unit.
