CONSTITUTION:On a kneading vessel 33, the cross-sectional area is formed roughly in the shape of U, and the internal side surface is formed in the shape of having an inclined surface spread upward, and a blade section 31 is removably set on a driving shaft 32 supported pivotally on the bottom section of the kneading vessel 33. The kneading blade section 31 is composed of a blade bearing section 35 fitted loosely on the driving shaft 32, and a blade plate 36 like a flat plate projected almost vertically from the section 35, and both the side surfaces of the blade bearing section 35 and the blade plate 36 are respectively formed in the inclined surface shapes (a), (b) of rough mountain types, and the inclined degree is set so that the inclined surfaces (a), (b) of both the side surfaces cannot be inclined exceeding a vertical surface even if the kneading blade section 31 is inclined by the backlash of a loosely fitted-on degree between the blade bearing section 35 and the driving shaft 32. As a result, when bread is taken out, then resistance in the removing direction of the bread is extremely reduced, and the bread can be easily taken out of the kneading vessel.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to an automatic bread maker that is used in general households and is capable of making bread by rotary kneading wheat flour and the like.

Conventional technology Generally, when making bread, equipment such as a kneading machine, two fermentation machines, a rolling pin, and an open oven are used. Making bread required considerable skill. In order to solve these problems, an automatic bread maker having a structure in which kneading, fermentation, and opening functions are housed in a single product as shown in FIG. 3 has been considered.

In the device shown in FIG. 3, a frame 2 is provided inside the main body 1, a firing chamber 6 equipped with a motor 3 and a heater 4 is fixed to the frame 2, and kneading blades are installed in the firing chamber 5. A kneading container 7 having a kneading container 6 is detachably attached thereto, and the rotational force of the motor 3 is transmitted to the kneading 9 blades 6 at a reduced speed through a small pulley 8, a belt 9, a large pulley 1o, and connectors 11 and 12.

13 is an upper lid that covers the firing chamber 6, and 14 is a timer, temperature, and power adjustment circuit. With this configuration, when bread ingredients are put into the kneading container and the timer is set, the operation starts at a predetermined time, and each step is automatically performed using the timer and temperature control, and the bread is baked at a predetermined time. It is.

Problems to be Solved by the Invention In such a conventional configuration, the kneading blade 6 has a configuration in which a part of the blade part is pivoted, and is movable from a horizontal state to an almost vertical state. After kneading the bread dough by repeatedly rotating it in a horizontal or vertical position in forward and reverse directions, the blades were returned to the horizontal position and the bread was baked.

However, with the above structure, the dough is baked with being pressed into the gap between the bottom of the kneading blade 6 and the bottom of the kneading container, so the kneading blade 6 is buried in the dough. , As a result, after baking, the kneading container 7
Even if the bread is taken out from the main body 1 and the kneading container 7 is turned upside down and shaken, it is difficult to take out the bread easily; Therefore, the quality of its appearance was impaired and it was not easy to use when taking out bread.

As yet another configuration, there is one that kneads and bakes bread dough using a combination of a rod-shaped kneading blade that is fixed by rotating in one direction and a kneading pin that protrudes from the inner surface of the kneading container. There is a hassle of having to attach and detach the dough each time, and when taking out the bread after baking, the kneading blades are buried in the dough, which is the same as in the above conventional structure. The inconvenience of use, including safety aspects, such as the need to always remove the kneading bar that has broken, is the same as that of the conventional structure described above.

The present invention was made to solve these problems, and by rationally setting the shape of the kneading container and kneading blades, it is possible to easily take out the bread from the kneading container, thereby realizing an easy-to-use automatic bread maker. The purpose is to provide opportunities.

Means for Solving the Problems In order to achieve the above object, the present invention forms a kneading container in the form of an inclined surface with an upwardly expanding inner surface, and the kneading blades are small and have a projected area as small as possible. shape, and the blade plate is configured in a flat plate shape protruding almost perpendicularly from the blade bearing part, and both sides of the blade bearing part and the blade plate are formed into a substantially mountain-shaped inclined surface shape, and the amount of inclination is as follows. Even if there is an inclination of the kneading blade due to loose fit between the blade bearing and the drive shaft, the slopes of both side surfaces are set so as not to incline beyond the vertical plane.

Function Since the automatic bread making machine of the present invention has the above-mentioned configuration, the resistance of the kneading container and the kneading blade portion in the direction of removing the bread can be minimized when taking out the bread, and as a result,
Since the bread can be easily taken out from the kneading container, its usability is greatly improved.

EXAMPLE Hereinafter, an example of the present invention will be described based on FIGS. 1 and 2. In the figure, 20 is the main body, 21 is the main body 2o
A motor 22 is fixed to this seven-plane chassis 21, and its rotational force is transmitted to a connector 24 located at the bottom of the firing chamber 23, and a small pulley 25. Belt 26. The signal is transmitted via the large pulley 27.

Further, a heater 28 is arranged on the inner peripheral surface of the lower part of the firing chamber 23, and a kneading container 33 is detachably attached inside the firing chamber 23. The container connector 3o is fixed to one side of the drive shaft 32, and the kneading blade part 31 is detachably attached to the other side. Then, when the kneading container 33 is installed in the baking chamber 23,
mJ connector 24 and container connector 3Q of kneading container 33
The temperature sensor 34 , which is elastically attached to the inner surface of the baking chamber 23 , comes into contact with the outer surface of the kneading container 33 .

The kneading blade portion 31 is composed of a blade bearing portion 35 loosely fitted onto the drive shaft 32 and a flat blade plate 36 projecting almost perpendicularly from the blade bearing portion 35.
extend from the vane bearing portion 35 in the radial direction substantially parallel to the bottom surface of the kneading container 33.

Here, as shown in FIGS. 2(a) and 2(b), the blade bearing portion 35 has a substantially conical shape with an inclined surface (a), and the blade plate 36 is also formed from a point on both sides to a lower end B. The lower part of the blade plate 36 is shaped like a wedge, and the other end surface of the blade plate 36 shown in FIG. It has a mountain-shaped sloped surface shape. And these slopes (2L) ~ (
d) and the blade bearing portion 35 loosely fitted onto the drive shaft 32, as shown in FIG. The inclined surfaces (a) to (d) are vertical lines V1. It is set so that it can be maintained at a certain angle with respect to V2°v6 without falling over the inclination.

Note that Fig. 2 (a) and (b) are inclined planes (IL).
, (b) are shown, but the inclined surfaces (0) and (d) shown in FIG. 1 have a similar relationship.

Further, the kneading container 33 has a substantially U-shaped cross section and an inner surface having an upwardly expanding inclined surface (e5).

Next, taking out the bread in the above embodiment will be explained. After baking the bread, when turning the dough container 33 upside down and pushing out the bread, it is important to minimize the resistance in the direction of ejection of the bread. 36 shape and flat blade plate 3
In addition to the effect of the shape of 6, as an improvement in mold releasability, the kneading container 33 is configured to have an inner surface with an upwardly widening inclined surface (6).

Further, regarding the mixing blade portion 31, the side surfaces of the blade bearing portion 35 and the blade plate 36 are formed with inclined surfaces (&) to (d), and the mixing blade portion 31 falls down due to backlash with the drive shaft 32. Also, the inclined surfaces (1) to (d) are vertical lines V4.
V2. It does not incline beyond V3 and prevents the dough from coming out in the direction of taking out the bread. Here, the gap between the drive shaft 32 and the blade bearing part 36 is set in consideration of the detachability of the kneading blade part 31.
In particular, if this gap is set extremely small, the bread dough will strongly adhere to the drive shaft 32 and the blade bearing part 36, causing a phenomenon in which the kneading blade part 31 cannot be removed. There is.

Further, for the above-mentioned reasons, it is desirable to set the horizontal point of the feather board 36 as close to the bottom end surface as possible; however, if it is set to the lowest surface, the bread dough under the kneading blade portion 31 tends to become large, and in this embodiment, The lower end of the blade plate 36 is wedge-shaped so that it can exhibit a knife effect when taking out the bread. In addition to reducing the amount of wraparound, the pull-out of the bread also reduces directional resistance. The horizontal point should be set by taking into account the height of the slats 36 and the hardness of the skin of the bread to be used.

Another point when taking out the bread is that it is important to improve the non-stickiness of the dough so that it does not stick.
It is made of die-cast aluminum and has a highly non-adhesive fluorine coating on its surface.

Effects of the Invention As is clear from the description of the above embodiments, according to the present invention,
The kneading container has a substantially U-shaped cross section and an inner surface having an upwardly expanding slope, and a kneading blade portion that is detachably attached to a drive shaft supported at the bottom of the kneading container. , the kneading blade portion includes a blade bearing portion that loosely fits onto the drive shaft;
A flat blade plate protrudes almost perpendicularly from the blade bearing part, and both sides of the blade bearing part and the blade plate are formed into a substantially mountain-shaped inclined surface shape, and the amount of inclination is the same as that of the blade bearing part. Even if the kneading blade part tilts due to play in the loose fit with the drive shaft of the kneading container, the slopes on both sides are set so as not to tilt beyond the vertical plane, so that the kneading container does not tilt when taking out the bread. Moreover, the directional resistance in removing the bread at the kneading blade part can be minimized, and as a result, the bread can be easily taken out from the kneading container, so that the usability can be greatly improved.
