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.

As shown in Fig. 7, this type of conventional frozen dessert maker has an outer container A filled with salt-containing ice B, and an inner container C inserted in the center so as to be buried in the ice B. Frozen dessert materials such as ice cream materials were put into this inner container C and stirred for a long time to produce frozen desserts such as ice cream.

However, this method generally uses ice cubes several centimeters square, and although the temperature of ice with 15% salt added can theoretically drop to -15°C, the actual temperature of ice only drops to about -5°C. Furthermore, 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. there was.

Further, in this type of conventional frozen confection making machine, since the outer container A is frozen during stirring and other times of producing frozen confectionery, there is a risk of frostbite, etc., and it cannot be said to be easy to handle.

This invention was made with the intention of solving the above problem, and its gist is that a refrigerant is sealed in the space and the outer edge of a sealed double container with a bottomed cylindrical shape that is open at the top. This sealed double container is placed inside a bottomed cylindrical outer container with a gap through an elastic ring that is fitted to the ring, and a lid that is removably fitted to the ring. A stirrer is rotatably supported in the center, and a handle is detachably attached to the rotary shaft of the stirrer, allowing the frozen dessert ingredients put into the sealed double container to be quickly poured from all surfaces. To provide a frozen dessert making device which is capable of producing frozen desserts such as ice cream in a short time by cooling and is capable of preventing frostbite during handling.

Examples of this invention will be described below based on the drawings.

Fig. 1 is a front view of the frozen dessert maker of this invention, Fig. 2 is a plan view thereof, and Fig. 3 is a vertical cross-sectional view thereof. A deep-squeezing inner container 2 and an outer container 3 are formed into a cylindrical shape with a bottom and open at the top, which are spaced from each other on the bottom and circumferential surfaces and are hemmed around flanges 4, 4, respectively.

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.

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

The cold storage agent 6 is, for example, a water or carbonated water base to which the required amount of organic or inorganic substances such as alcohol, glycol, ethylene glycol, and sodium chloride, as well as an organic thickener to achieve the desired viscosity, are added. The melting temperature is adjusted to be within the range of -7°C to -80C ITC.

8 is a ring, which is made of flexible synthetic resin such as ethylene-vinyl acetate copolymer, or rubber, and its cross section has a downward slope toward the outside as shown in FIG. A pair of legs 8b and 8c are suspended from the inner lower part of the triangular base 8a to form a sealed double container upper edge fitting part 8d between the two legs 8bt8c, and a triangular shape with the outer leg 8C. The lower surface of the triangular base 8a forms a supporting stepped portion 8e by the outer container 9, and the outer peripheral leg portion 8b and the inner peripheral surface of the triangular base 8a form a lid holder portion 8f. .

The outer container 9, which has a cylindrical shape with a bottom, is fitted so as to support the support step 8e of the ring 8 formed as described above.
It is made of synthetic resin or the like, supports the support step 8e of the ring 8, and is adapted to house the sealed double container 1 with a gap 10 therebetween.

In this case, support ribs 11, 11, 11, 11, 11, 11, 11, 11, 11, 11, 11, 11, 11, 11, 11, 11, 11, 11, 11, 11, 11, 11, 11, 11, 11, 11, 11, 11, 11, 11, 11, 11, 11, 11, 11, are protruded from the inner peripheral surface of the bottom of the outer container 9 at appropriate intervals (see FIG. 3).
The sealed double container 1 is supported by the container 9, and a gap 10 is formed between the bottom surface and the circumferential surface of the outer container 9.

Furthermore, a handle 9a is provided on the outer surface of the outer container 9 to facilitate handling during production of the frozen dessert.

On the other hand, a transparent synthetic resin lid 12 is removably fitted into the lid holder portion 8f of the ring 8.

In this case, a bearing 13 is provided in the center of the lid 12 to rotatably support an agitator 14, 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 16 is provided for receiving a rotating shaft 15 forming a part of the rotary shaft 15 .

The stirrer 14 includes a large diameter portion 15 (see FIG. 5) having a fitting groove 15a with a mouth-shaped cross section at the upper end;
A pair of agitating shafts extending laterally from the upper and lower diagonal positions of the small-diameter portion 15c of the rotating shaft 15, each consisting of a small-diameter portion 15c continuous below the b, and whose tips are close to the inner circumferential surface of the sealed double container 1. The handle 18 is entirely formed in the shape of a crank, and has a protruding blade 17, 17, and a connecting rectangular cylindrical shaft 18a that is removably fitted into the fitting groove 15a of the rotating shaft 15. , rotating shaft 15 and stirring blade 17.
17 is adapted to be rotated.

In this case, each of the stirring blades 17 and 17 is connected to the rotating shaft 1.
5 are formed parallel to each other with a gentle inclination of about 10 to 20 degrees with respect to the axis of the container 1, so that the frozen dessert material put into the sealed double container 1 can be stirred uniformly.

Further, the handle 18 is composed of a crank-shaped handle main body 18b having a connecting shaft 18a at one end below, and a knob 19 rotatably attached to the upper end of the other end of the handle main body 18b. A cap 21 is removably fitted into a recess 20 formed on the top surface.

This cap 21 is also detachably fitted to the bearing 13, and when the agitator 14 is not in use, the cap 21 is fitted onto the bearing 13 from which the agitator 14 has been removed. This allows it to be used as a cooling container such as an ice bucket.

In addition, in the frozen dessert maker of this invention configured as described above, the lid 12 is attached to the support step 8e inside the ring 8.
Since the ring 8 and the ring 8 are fitted together with elastic force, the inflow of outside air into the sealed double container 1 is prevented, and rotation of the ring 8 and the sealed double container 1 is also prevented.

Regarding the outer container 9 and the sealed double container 1, for example, as shown in FIG. By providing a rotation prevention protrusion 23 that engages with the rotation prevention recess 22 and engaging the rotation prevention depression 22 and the rotation prevention protrusion 23 with each other, rotation of the sealed double container 1 can be prevented. can.

In this case, the same effect can be obtained by providing a rotation prevention projection on the edge of the outer container 9 and forming a recess that can engage with the rotation prevention projection at an arbitrary location on the ring 8.

Another method is to provide a detent recess or protrusion at any location on the outside of the double sealed container 1, and provide the outer container 9 with a detent that can engage with the detent recess or protrusion. Rotation of the double sealed container 1 can be prevented by providing a convex portion or a concave portion and engaging these portions with each other.

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, the outer container 9, the lid 12, and the stirrer 14 are assembled at a predetermined location, and the frozen dessert material is put 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 if you repeatedly stir it with the stirring blades 17 and 17 of the stirrer 14 so as to scrape it off, the entire frozen dessert material will become ice cream-like in a few minutes. Or it becomes sherbet-like.

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 easily produce frozen desserts in a shorter time than conventional ice creams, eliminating the hassle of handling ice, and being able to be reused semi-permanently. It is possible to prevent the inflow of outside air and the inflow of outside air into the inside of the sealed double container, and together with the gap between the sealed double containers, the insulation function can be improved.
The lid body etc. can be securely fitted.

In addition, the ring serves as a handle when lifting a frozen double-sealed container, and since it has insulation properties, it has excellent effects such as preventing frostbite, etc., so its utility value is remarkable. be.
