In the conventional bread maker constructed as described above, the bread container 6 is fixed by first pressing the bread container 6 from a top position to a lower position in a predetermined position, and setting the container fixing spring 11 outward. The bread container 6 was moved over while being bent, and the upper portion of the bread container 6 was locked by a container fixing spring 11.

[0004]

In the conventional bread maker described above, a play is provided between the bread container 6 and the container fixing spring 11 in order to prevent the bread container 6 from rattling vertically and horizontally due to the pressing of the container fixing spring 11. There is almost no container fixing spring 1
Since the pressing force due to the elasticity of 1 is also strong, it is necessary to pay attention to aligning the bread container 6 at a predetermined position, and it takes considerable force to attach and detach the bread container.

Therefore, the operability of attaching and detaching the bread container 6 is poor.
There was a problem that too much force was applied during attachment and detachment, causing spilling of the bread material at the time of insertion, and causing burns by directly touching the high-heat bread container 6 immediately after baking at the time of detachment. In addition, bread container 6
It is easy to misuse when the product is not inserted correctly, and the bread does not burn well and wastes the bread material, or causes abnormalities such as breakage and thermal deformation of a part of the product. There was a problem with sex.

Also, in the production of the bread container 6, since the cylindrical ribs 8 far from the gate located on the inlet side are apt to be insufficiently filled deeply, the pressure during molding is increased to make the shot cycle longer. However, it was necessary to secure a minimum thickness of 2.2 or more to improve the flow of aluminum. Therefore, it is necessary to use a large-sized die-casting machine at high pressure and to make the bread container 6 thick, and the operating cost of the production equipment and the material cost of the aluminum used are high, resulting in high costs. Further, since the container fixing spring 11 for fixing the bread container 6 is composed of a plurality of parts and is fixed to the left and right sides of the baking chamber 4 by screwing, the number of parts and the number of assembly steps are increased.

SUMMARY OF THE INVENTION The present invention solves such a problem, and improves the operability of attaching and detaching a bread container to improve usability, prevent erroneous use and unsafety, and reduce the number of parts and cost. It is to plan.

The operation member performs setting of menu and baking time, start of cooking, and the like.

The operation of the above-described bread maker when the bread container 31 is set in the baking chamber 23 will be described. First, as shown in FIG. 2 and FIG.
The bread container 31 in which the bread ingredients are set while aligning the positions of the inscriptions 42 and 43 on the upper surface of the bread container 3 and the bread container 31.
When the is lowered, the locking portion 39 enters the entrance of the concave portion 41 which is tapered and formed largely, and while being guided by the concave portion 41 by the weight of the bread container 31, the lower end surface of the bread container base 35 is attached to the container. It is inserted to a position where it comes into contact with the bottom surface of the table 24, and is located near the entrance of the hole 40. Next, the operation member 4
When the kneading process is started by operating the kneader 8 to start the kneading process, the bread is rotated in the direction in which the bread container 31 is fixed by the impact of the bread material hitting the inner surface of the bread container 31 because there is a gap in the fitting dimension. At the same time, the locking portion 39 is fitted into the hole 40, and the bread container 31 is automatically fixed to the container mount 24. Of course, the bread container 31 can be fixed to the container mount 24 in the same manner as described above by holding the handle 44 and twisting the bread container 31 in the direction in which the bread container 31 is fixed according to the mark of the arrow.
Further, the kneading and degassing of the bread dough are performed by one-way rotation, and only a rotational force in the fixed direction is applied to the bread container 31. Therefore, the bread container 31 does not come off, and the bread container 31 can be removed easily and lightly.

As described above, according to this embodiment, the locking portion 3
9 and the concave portion 41, the fitting portion between the bread container base 35 and the container mounting base 24 is tapered, the fitting dimension is set with a gap, and the bread container is fitted and inserted by its own weight and the driving force of the motor. By allowing the bread container 31 to be worn, the operability of attaching and detaching the bread container 31 and the usability can be greatly improved, and unsafety such as cooking failure, breakage of each part, burns, etc., which has conventionally occurred due to poor detachability. Problems can also be prevented. Moreover, since the bread container 31 can be fixed only by fitting the container mounting table 24 and the bread container table 35, another part for fixing the bread container 31 such as a conventionally required container fixing spring is unnecessary,
It is also possible to reduce costs by reducing the number of parts and the number of assembling steps.

Further, as shown in FIG.
By arranging a part of the bread container 31 at an angle of about 10 ° so that the angle 0 and the concave portion 41 do not become an equal arrangement angle, even if the bread container 31 is inserted in an incorrect position, Since the position of 41 is different and the locking portion 39 hits the upper end of the container mount 24 and becomes impossible and the bread container 31 can be fitted and inserted only at a predetermined position, the bread container 31 is erroneously inserted. Can be reliably prevented, and abnormalities such as cooking failure and damage or thermal deformation of the product can be prevented.

Further, by dividing the bread container 31 formed of aluminum die-casting into separate parts of the container part 34 and the bread container base 35, the distance from the gate is shortened and the shape of the parts is simplified. As a result, the shot cycle can be shortened by lowering the pressure during molding, and the occurrence of insufficient filling can be prevented even if the conventionally required 2.2 thickness is reduced to about 1.5. became. Therefore, the die-casting machine to be used can be changed to a slightly smaller one, which improves productivity and reduces aluminum consumption by 30%.
The cost of operating production facilities and the cost of aluminum materials can be significantly reduced.

[0016]

As described above, according to the present invention, the fitting portion between the bread container base and the container mounting base, such as the locking portion and the concave portion, is tapered, and the bread container is fitted and inserted by its own weight and the driving force of the motor. By doing so, the operability of attaching and detaching the bread container and the usability can be greatly improved, and a separate part for fixing the bread container, which was required in the past, becomes unnecessary, so the number of parts and assembly man-hours Can be reduced.
