Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a frozen dessert maker for general household use.

Conventional Structure and Problems Conventionally, in this type of frozen dessert maker, as shown in FIG. Freeze. Then, this cooled refrigerant container 2 is transferred to the outer container 3.
Then, the lower end of the stirring blade 4 is brought into contact with the recess 7 provided in the inner bottom of the refrigerant container 2, and the material is placed in the refrigerant container 2, the lid 5 is closed, and the handle 6 is inserted into the stirring blade By engaging the handle 6 and stirring the ingredients with the stirring blade 4, frozen desserts such as ice cream and sherbet were made.

However, when putting the refrigerant container 2 in the freezer to cool it, if the water is not thoroughly wiped off, water may accumulate in the recess 7 on the inner bottom and freeze as it is.
There was a problem that the water added during use would freeze in that part, making it difficult to properly set the stirring blade 4, resulting in trouble and failure in making frozen desserts.

OBJECTS OF THE INVENTION The present invention solves these conventional problems and provides a frozen dessert maker with improved usability.

Structure of the Invention In order to achieve the above object, the frozen dessert maker of the present invention has a refrigerant container in which a refrigerant is sealed in the bottom, and a substantially spherical convex portion is provided at the center of the inner bottom of the refrigerant container, and a substantially spherical convex portion is provided at the bottom of the corresponding stirring blade. By providing a spherical concave portion and supporting the rotary shaft, it is possible to solve the problem that the stirring blade cannot be set due to freezing of residual water or input water.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to the accompanying drawings. In FIG. 1, 8 is a refrigerant container in which a refrigerant 1 is sealed in the side wall and the bottom of the container.
The outer container 3 and the lid 5 cover the container to prevent cold air from escaping. A substantially spherical convex portion 9 is provided approximately at the center of the inner bottom of the refrigerant container 8, and a substantially spherical concave portion 1 is provided at the bottom surface.
A stirring blade 11 having a diameter of 0 is supported between it and the lid 5. Further, a handle 6 is engaged with the upper part of the stirring blade 11, and by turning the handle 6, the stirring blade 11 is rotated.

To explain the operation in the above configuration, the refrigerant container 8 is placed in a freezer and cooled for several hours to freeze the cold storage agent 1. The cooled refrigerant container 8 is set in the outer container 3, the stirring blade 11 is further set in the center of the refrigerant container 8, and the frozen dessert ingredients are placed therein. Then, the lid 5 is put on and the handle 6 is fitted with the stirring blade 11. The material in the refrigerant container 8 begins to freeze from the part that comes into contact with the inner peripheral surface of the refrigerant container 8. Therefore, by turning the handle 6 and scraping off the frozen material with the stirring blade 11, the material in the entire refrigerant container 8 is uniformly distributed. When mixed together, frozen desserts such as ice cream and sherbet can be made. Here, the contact between the refrigerant container 8 and the stirring blade 11 is achieved by providing a protrusion 9 on the refrigerant container 8 side and a recess 10 on the stirring blade 11 side. The material freezes in the recess, making it difficult to set up the stirring blade 11, and the moisture in the material that flows into the recess during use is frozen by the cold storage agent at the bottom, making it impossible for the stirring blade to pivot. There is nothing to do. Furthermore, since the mating concave and convex surfaces are spherical, rotation is smooth and cleaning after use is easy, which has great practical effects.

Effects of the Invention As is clear from the above embodiments, the frozen dessert maker of the present invention has a refrigerant container in which a refrigerant is sealed in the bottom and a shaft support structure for the stirring blade, and a substantially spherical convex structure in the center of the inner bottom of the refrigerant container. By providing a substantially spherical concave portion on the lower surface of the stirring blade, residual water and inflow water will not freeze at the inner bottom of the refrigerant container, and frozen desserts can be easily made at home without failure.
