Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an ice cream machine that easily makes ice cream by rotating a cream container containing an ice cream material and having stirring blades in a cooling material.

An embodiment of the present invention will be described below with reference to the accompanying drawings.

In the figure, 1 is a cream container containing milk, eggs, sugar, and other ice cream ingredients; 2 is a container lid that is detachably attached to the opening of the cream container 1 and engages with the cream container 1 in the rotational direction; 3; 5 is a stirring blade equipped in the cream container 1 with an engaging portion 4 protruding from the container lid 2;
8 is a case that rotatably accommodates the cream container 1 and forms a housing section 7 between the cream container 1 and the outside for accommodating a cooling material 6 such as ice or salt, and 8 is connected to the opening of the case 5 by bayonet connection. The main body 9 attached in a bridging manner is a drive section having a motor 10 provided in the center of the main body 8 and a gear part 11.

This gear portion 11 includes a first gear 13 formed on the shaft of a motor 10 having a cooling fan 12, a second gear 14 meshing with this gear, and a first gear 14 formed on the shaft of a motor 10 having a cooling fan 12.
and a third gear 15 that meshes with the third gear 15.

Further, the third gear 15 has a toothed portion 16 formed at its center, and is fitted into the toothed portion 17 at the center of the container lid 2 described above so as to enable power transmission.

Reference numeral 18 indicates an engagement portion of the main body 8 that removably engages with and fixes the engagement portion 4 of the stirring blade 3, 19 indicates a motor cover provided to cover the motor 10, and 20 indicates a motor cover 19.
This is the intake hole.

The use of the above ice cream maker will be explained.

First, each part is assembled into the state shown in FIG. Before being assembled in this state, milk, eggs, sugar, and other ice cream ingredients are stored in the cream container 1, and cooling materials such as ice and salt are stored in the storage part 7. be.

Here, when the motor 11 is driven, it is decelerated by the first to third gears 13, 14 and 15, and the cream container 1 is rotationally driven via the container lid 2.

The stirring blade 3 is maintained at a constant position without rotating due to the action of the engaging portions 4 and 18.

Therefore, the ice cream material in the cream container 1 is cooled from the outside and stirred inside to form a soft cream-like product.

Ice cream is made in the above manner.
This system divides ice cream into two upper and lower stages, and uses a more effective cooling method to quickly make ice cream in a single storage space.

In the embodiment shown in FIG. 2, an annular partition plate 21 formed of resin on a part of the bottom side of the case 5 is fixed to the case 5 by welding or the like.

Note that a slight gap a is provided between the outer wall of the cream container 1 and the inner circumferential wall of the partition plate 21.

The housing section 7 for the cooling material 6 of the case 5 is connected to the partition plate 2.
1, it is divided into two stages, an upper stage part 7a and an upper stage part 7b.

Initially, the cooling material 6 is stored in the upper part 7a, and during operation, the cooling material 6 is melted, that is, salt water 22 (hereinafter referred to as salt water 22).

) falls and accumulates in the lower part 7b.

Therefore, the upper part 7 of the housing part 7 for the cooling material 6 of the case 5
The cooling material 6 (
ice, salt, etc.), and an effective cooling material 6 with a low melting temperature can always be supplied in contact with the outer wall of the cream container 1 for a certain period of time during operation.

Therefore, the ice cream ingredients can be solidified more quickly, and better ice cream can be made more quickly.

In the embodiment shown in FIGS. 3 to 5, an annular partition plate 24 is attached to a guide rib 23 provided vertically at the bottom of the inner wall of the case 5.
The partition plate 24 is inserted into the accommodating part 7 for the cooling material 6 of the case 5, with the notch 25 provided in a part of the outer periphery of the partition plate 24 aligned.

The partition plate 24 is prevented from rotating by the action of the guide ribs 230 of the case 5.

Further, since there is a slight gap between the partition plate 24 and the outer wall of the cream container 1, the salt water falls below this gap.

In addition, in the case of this partition plate 24, at the beginning of operation, the cooling material 6
By pressing downward and \, the partition plate 24 is moved to the housing part 7 of the case 5.
It is located on the lower end surface, and when the amount of salt water 22 accumulates, it is positioned upward in proportion to the amount, and when the cooling material 6 is increased (for example, when it is added midway through), it is positioned downward in proportion to the amount.

That is, the position is determined by the balance between the buoyancy of the salt water 22 and the pressing force of the cooling material 6.

In this way, in the case of FIGS. 3 to 5, at the beginning of operation, the cooling material 6 is brought into contact with the entire outer wall of the cream container 1, that is, up to the lower end surface, and then the position is gradually raised by the buoyancy of the salt water 22. The cooling material 6 can be held in the upper part 7a of the storage part 7 of the case 5 without being exposed to the salt water 22, and the cooling effect of the cream container 1 at the beginning of operation can be further enhanced.
Furthermore, even during operation, the cooling material 6 and the salt water 22 can be divided into the upper stage part 7a and the lower stage part 7b.

Next, in the case of the embodiment shown in FIGS. 6 and 7, the annular partition plate 26 made of metal is placed on the outer periphery of the cream container 1 with a slight gap C between it and the inner wall of the case 5. The partition plate 26 has a plurality of convex portions 27 and 28 such as ribs on the upper and lower surfaces thereof, respectively.

In the case of this partition plate 26 as well, the case 5
The accommodation section 7 for the cooling material 6 is divided into an upper section 7a and a lower section 7b, and the salt water 22 is stored in the lower section 7bVc by a gap C.
It settles and accumulates.

In the case of this partition plate 26, the protrusions 2T play the role of melting the cooling material quickly by cutting ice, and the protrusions 28
has the role of sufficiently dissolving the salt in the salt water 22 and maintaining the temperature of the salt water 22 at a low temperature by stirring the salt water 22 accumulated in the lower part 7b.

That is, the convex portions 27 increase the contact area of the refrigerant (cooling material 6) with the cream container 1 by melting the cooling material 6 quickly, and the convex portions 28 have the following properties.

The salt in salt water 22 is dissolved by stirring, and the salt in salt water 22 is dissolved.
The cooling effect of both the upper section 7a and the lower section 7b is further increased by further lowering the temperature of the partition plate 2.
Since 6 is made of metal, the cream container 10
They also function as so-called cooling fins, increasing the surface area and enhancing the cooling effect.

As described above, the ice creamer of the present invention has a cooling material accommodating section of the case basically consisting of an upper section containing the cooling material and a lower section containing the salt water in which the cooling material is dissolved. The case is divided into upper and lower sections to provide a more effective cooling effect for the single-stage housing section of the case.
