Description

[Detailed Description of the Invention] This invention relates to a frozen dessert maker that can easily produce frozen desserts such as ice cream and sherbet by cooling mainly in a household refrigerator.

In a conventional frozen dessert maker of this kind, for example, as shown in Figure 1, ice B containing salt is placed in an outer container A, and an inner container C is inserted in the center so as to be buried in the ice B. A frozen dessert material such as an ice cream material is put into the inner container C and stirred for a long time to produce a frozen dessert such as ice cream.

However, this method generally uses ice cubes several centimeters square, and although the temperature of ice containing 15% salt can theoretically drop to -15°C, the actual temperature of ice is only about -5°C. Moreover, since there is point contact between the outer surface of the container and the ice, the frozen dessert ingredients in the inner container C cannot be cooled quickly, and therefore it takes a considerable amount of time to make frozen desserts such as ice cream. It was.

This invention was made with the intention of solving the above problem, and its gist is that a sealed double-walled cylinder with a bottom and an open top is filled with a cold storage agent in the space extending over the bottom and curved surfaces. a container, a cylindrical outer container with a bottom that houses the sealed double container with a gap therebetween, a lid that is removably fitted into the opening of the double container or the outer container, and the lid. Q: The stirrer is rotatably supported at the center, and the stirrer is rotatably supported at the upper end by the lid and the lower end is supported at the center of the inner bottom of the sealed double container. A rotating shaft, a stirring blade protruding from the side of the rotating shaft to a position close to the inner surface of the sealed double container, and a handle that is detachable from the rotating shaft. The aim is to provide a frozen dessert maker.

Embodiments of this invention will be described below with reference to FIGS. 2 to 4.

In the figure, reference numeral 1 denotes a sealed double container, in which a deep-squeezed inner container 2 and an outer container 3 made of, for example, aluminum alloy are spaced apart from each other on the bottom and circumferential surface, and are wrapped around each other at flanges 4, 4. It has a cylindrical shape with a bottom.

In this case, the inner container 2 and the outer container 3 are formed by deep drawing an aluminum alloy plate and then applying an anodic oxide film to the entire surface thereof.

Furthermore, a cold storage agent 6 is sealed in a space 5 extending over the bottom and circumferential surfaces formed between the inner and outer containers 2 and 3, leaving a predetermined gap 7 before being tightened.

This cold storage agent 6 is, for example, based on water or carbonated water to which a necessary amount of an organic or inorganic thickener such as alcohol, glycol, ethylene glycol, or sodium chloride is added to achieve a desired viscosity. Its melting temperature is adjusted to a range of -7°C to -17°C.

Reference numeral 8 denotes a ring made of synthetic resin, and is elastically attached to the wrapped portion of the double sealed container 10 so that a recess 9 on the inner circumferential surface thereof fits.

The sealed double container 1 configured as described above is formed into a cylindrical shape with an open top and a bottom, and a predetermined gap 11 is provided in an outer container 10 made of synthetic resin and having a cylindrical shape with an open top and a bottom.
A lid 12 is removably fitted into the opening of the outer container 10.

In this case, the sealed double container 1 is supported by support pieces 13, 13, etc. (see FIG. 3) protruding from the inner peripheral surface of the bottom of the outer container 10 at appropriate intervals, and the outer container 1
A gap 11 is formed between the bottom surface and the curved surface of 0.

Further, the lid body 12 is formed of transparent synthetic resin or the like,
An annular protrusion 14 provided near the outer periphery of the lower surface of the outer container 10 can be detachably engaged with a stepped circumferential groove 15 provided at the opening of the outer container 10.

Note that the lid 12 may be fitted into the opening of the sealed double container 1.

On the other hand, a bearing 16 is provided at the center of the lid 12 to rotatably support a stirrer 18, which will be described later.

Further, the stirrer 1 is placed in the center of the inner bottom of the sealed double container 1.
A recess 17 is provided for receiving a rotating shaft 19 forming a part of the rotary shaft 8 .

The agitator 18 is connected to the upper and lower diagonal positions of the small diameter portion 19c of the rotating shaft 19, which is composed of a large diameter portion 19b having a cross-shaped spline groove 19a at the upper end and a small diameter portion 19c continuous below the large diameter portion 19b. A pair of stirring blades 20.20 are provided protruding from the side and the tips thereof are close to the inner circumferential surface of the sealed double container 1, and are removably fitted into the spline groove 19a of the rotating shaft 19. The rotating shaft 19 and stirring blades 20, 20 are rotated by a handle 21 which is entirely formed in the shape of a crank and has a mating splined shaft 21a for connection.

In this case, each of the stirring blades 20 and 20 is connected to the rotating shaft 1.
They are formed parallel to each other with a gentle inclination of about 10-20' with respect to the axis of the container 9, so that the frozen dessert material put into the sealed double container 1 can be stirred uniformly.

Further, the handle 21 has a connecting spline shaft 21a.
an L-shaped handle body 21b having one end downwardly;
This... consists of a knob 21c that is rotatably attached to the upper part of the other end of the handle body 21b, and the lid body 1.
2, when the spline groove 19a of the rotating shaft 19 and the spline shaft 21a of the handle 21 are fitted together, the neck portion 2 continues to the base of the spline shaft 19a.
1d is rotatably supported by a bearing 16.

To manufacture frozen desserts using the frozen dessert maker of this invention configured as described above, first, place a sealed double container 1 in a refrigerator.
is cooled for several hours to freeze the cold storage agent 6 inside.

Next, the sealed double container 1 and the outer container 1 are placed in a predetermined place.
0. Assemble the lid 11 and the stirrer 18, and put the frozen dessert ingredients into the sealed double container 1.

At this time, the frozen dessert material becomes a thin layer and freezes inside the sealed double container 1, so it is scraped with the stirring blades 20 and 20 of the stirrer 18 whose side edges are in sliding contact with the inner wall surface of the sealed double container 1. When repeatedly stirred, the entire frozen dessert material becomes ice cream-like or sharpen-like in a few minutes.

As explained above, according to the frozen dessert maker of this invention, the sealed double container that encloses the cold storage agent is placed inside the bottomed cylindrical outer container with a gap in between, which makes it easier to use water than in the past. It has the advantage of being able to produce frozen desserts more easily and in a shorter time than conventional ice creams, eliminating the hassle of handling ice, and being able to be used repeatedly semi-permanently.Furthermore, the gaps have a heat insulating function, making them airtight. It is possible to prevent the double container from being heated by the outside air, and the synthetic resin ring fitted into the opening of the sealed double container can prevent frostbite on hands and the like.

The overall size can be made smaller than the conventional one.

In addition, by rotating the handle □, the stirring blade scrapes off the frozen layer of frozen dessert material on the inner circumferential surface of the sealed double container, making it possible to produce frozen desserts such as ice cream or sherbet in a short time. Moreover, since the stirrer can be disassembled into the handle, rotating shaft, and stirring blades, it is easy to wash with water after use, making it hygienic, and it is also convenient because it can be stored compactly. Furthermore, even if the stirring blade is frozen together with the frozen dessert in the sealed double container, excellent effects such as the ability to disassemble the handle without damaging the stirring blade can be obtained, and its utility value is remarkable.
