Description

[Detailed Description of the Invention] The present invention relates to a kneading device for kneading flour, etc. by rotating kneading blades.

In a conventional device of this kind, after a pail is set on a base, a kneading blade is attached to a drive shaft protruding from the inner bottom of the pail, and then flour or the like is stored in the handle.

For this reason, it is necessary to secure a space above the tub for installing kneading blades in the handle or for introducing ingredients, and therefore it is necessary to integrate the oven etc. and store the tub removably inside the cooking tank. However, the height of the tub is limited, making it impossible to secure a sufficient tub volume, and the operations such as attaching kneading blades or adding materials after attaching the tub are troublesome.

The present invention was developed in view of the above circumstances, and includes a holding device that holds the kneading blades in a predetermined state at the inner bottom of the tub that has been removed from the base.When the bucket is set on the base, the kneading blades By separating the kneading blades from the holding device and connecting them to the drive shaft, it is possible to hold the kneading blades at the inner bottom of the tub and charge the material into the handle before setting the tub on the base. Therefore, the space above the tub set on the base can be reduced to the necessary minimum, and the volume of the tub can be secured to the required level, and various operations such as loading materials, attaching kneading blades, and setting the tub can be performed. It is an object of the present invention to provide a kneading device that can be easily operated.

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

1 is an outer box serving as a base, 2 is a heating tank provided inside the outer box 1 so that the front can be opened and closed with a door (not shown), and 3 is arranged at the upper and lower parts of this heating tank 2. A heater 4 is a boiler tank with an open top container shape as a base disposed at the bottom of the heating tank 2, 5 is a heater that heats the boiler tank 4, and 6 is a central cylindrical part 7 of the boiler tank 4. 8 is a drive motor as a rotary drive device; 9 and 10 are pulleys; 11 is a belt; The bucket 14 is a kneading blade having a shaft hole 14a for removably fitting into the upper end of the drive shaft 6.

In the following, the tub 12, tub support plate 13, and kneading blade 14 will be described in detail. Reference numeral 15 is a shaft insertion hole formed in the center of the tub support plate 13, and the peripheral edge thereof is bulged annularly by a predetermined size upward. and its inner diameter is set to d□.

Reference numeral 16 denotes an abbreviated protruding section 16 as a holding device which is bulged on the upper surface of the tub support plate 13 so as to surround the shaft insertion hole 15, and the protruding strip 16 is provided on the bottom surface of the tub 12 so as to protrude upward. Hole 12
b is provided, and the dimension from the inner bottom surface of the tub 12 to the upper end of the protruding strip 16 is t□.

Further, on the lower surface of the kneading blade 14, a concave portion 17 is formed which has a 0-shape approximately equal to the outer peripheral shape of the convex strip portion 16 and has a different depth. A boss portion Y9 having an outer diameter approximately equal to d1 is formed around the shaft hole 14a.

Incidentally, flat parts 6a and 14b for rotation transmission are formed at the upper end of the drive shaft 6 and the shaft hole 14a, respectively, and the kneading blades 1
Four wing pieces 14c are opposed to each other with the plane portion 14b and the shaft hole 14a in between.

Moreover, 20 is a convex part made to correspond to the flat part of the convex strip part 16 at the upper end of the tub as an indicator when setting the tub.

The sequence of operations when kneading, for example, wheat flour using the apparatus having the above configuration will be explained with reference to FIG.

When the kneading blade 14 is inserted into the tub 12 removed from the heating tank 2 and the convex portion 16 and the concave portion 17 are engaged, the kneading blade 14
in a predetermined state, that is, the flat part 14b of the shaft hole 14a and the convex part 20
The boss portion 19 is held in a state in which the direction of
is inserted into the shaft insertion hole 15.

After this, the flour material is stored in the bucket 12 (Fig. 4a,
b).

Next, insert the tub 12 into the heating tank 2 while aligning the protrusion 20 so that it faces in the same direction as the flat part 6a of the drive shaft 6,
The shaft insertion hole 15 is made to correspond slightly above the drive shaft 6 (see FIG. 4C).

After this, when the tub 12 is gradually displaced downward, the drive shaft 6
is fitted into the shaft hole 14a with its flat portion 6a aligned with the flat portion 14b.

Then, when the tub support plate 13 is placed on the stepped portion 4a of the boiler tank 4, the kneading blade 14 is lifted upward by a predetermined distance t2 by the drive shaft 6, and the engagement between the protruding portion 16 and the recessed portion 17 is released. , a gap is also created between the upper end of the convex strip 16 and the lower surface of the kneading blade 14.

After the drive shaft 6 is fitted into the shaft hole 14a of the kneading blade 14 in this manner, the tub 12 is rotated in a predetermined direction and the tub support plate 13 is engaged with an engagement device (not shown) provided on the stepped portion 4a. let me,
Thereafter, when the drive motor 8 is energized, the kneading blades 14 are rotated and the flour in the tub 12 is kneaded.

In addition, when producing rice cakes by kneading the Japanese rice cake in the tub 12, water for steaming is filled in the boiler tank 4 in advance, and the washed Japanese Japanese rice is stored in the tub 12 and then mixed as described above. The tub 12 is placed and supported on the stepped portion 4a of the boiler tank 4 in the order shown in FIG. The rice is then kneaded to make mochi.

As is clear from the above description, the present invention makes it possible to hold the kneading blades at the inner bottom of the tub and to charge the material into the handle before setting the tub on the base. It is possible to reduce the space above the set tub to the minimum size required only for setting the tub, and it is possible to secure sufficient volume of the tub, and to easily insert materials, attach kneading blades, and It is possible to provide a kneading device that can easily perform various operations such as setting.
