Conventionally, in order to manufacture ice cream using a refrigerator, first, ice cream ingredients (for example, milk, fresh cream, sugar, eggs, vanilla flavor, etc.) are put in a separate container and manually mixed using a rod-shaped rod. The mixed ice cream stock solution was put in a separate container and used to freeze in a freezer for a predetermined time.

However, the method of making ice cream as described above was inefficient in time and effort for making ice cream by manually mixing the ice cream stock solution.

Therefore, a new ice cream maker which mechanically mixes the ice cream material and then separates the container and puts it into the refrigerator is also proposed, but this also forms a layer between the upper and lower portions during the freezing of the ice cream, and the air during the freezing of the ice cream. There is a problem that the ice cream forms an assembly structure because there is no supply of.

The support plate 4 installed in the structure is provided with a manufacturing vessel 6 for receiving the power of a separate electric motor (not shown) is transmitted to the reduction gear (5) to rotate.

The ice cream maker opens the lid 7 of the manufacturing container 6, loads the ice cream raw material into the manufacturing container 6, locks the lid 7 and puts the manufacturing container 6 in place to the electric motor control switch 8 When the electric motor is turned on, the manufacturing vessel rotates through several reduction gears 5, and as the manufacturing vessel 6 rotates, the ice cream raw material charged therein is mixed and gradually cooled to prepare ice cream.

However, the ice cream maker has the effect of preventing the sediment is formed to some extent by simply rotating the container without a separate stirring device, but in the freezing process of the ice cream does not supply enough air to give a soft taste of the ice cream There was a difficulty.

In addition, since the ice cream can be manufactured only by installing a separate electric motor that can transmit the rotational force to the reduction gear in the refrigerator compartment of the refrigerator, people having the existing refrigerator cannot use it.

The present invention has been devised to solve the above problems, the rotational force transmitted from a separate power source in the state coupled to the cooling fins to enhance the cooling effect on the outside of the main body, which is an ice cream manufacturing container to the key through the motor reducer. And a mixing blade coupled to the lower portion of the mixing shaft by rotating the mixing shaft linearly coupled to the key, to provide an ice cream maker having an electric motor and a stirring device integrally mixing the ice cream stock solution during the freezing process. There is a purpose.
