Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to rotary blades of an automatic bread maker, and more particularly to a structure for preventing the rotary blades from coming off during rotation.

[0002]

[Prior Art]

 A rotary blade of a conventional automatic bread maker comprises a shaft portion that is detachably fitted to a rotary shaft that penetrates the bottom of a bread container, and a blade portion that extends from the shaft portion in a direction perpendicular to the rotary shaft. I am When kneading bread dough with this rotary blade, especially when a small amount of bread dough is used, the bread dough may enter between the lower edge of the blade or the lower end surface of the shaft and the bread container, and the rotary blade may come off the rotary shaft. .. For this reason, conventionally, a locking mechanism has been provided on the rotary shaft and the rotary blade.

[0003]

[Problems to be solved by the device]

 However, the conventional structure has a problem that it is difficult to take out the blade from the rotary shaft because the rotary blade does not easily come off due to the lock mechanism. The present invention aims to solve such a problem, and provides a rotary blade of an automatic bread maker which does not come off when kneading bread dough and can be easily taken out after baking is completed. The purpose is to

[0004]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, an automatic manufacturing system comprising a shaft portion that is detachably fitted to a rotation shaft that penetrates the bottom of a bread container, and a blade portion that extends from the shaft portion in a direction perpendicular to the rotation shaft. In a rotary blade of a bread machine, the first invention is a blade provided with a flange protruding obliquely downward toward the rotation direction at the lower edge of the blade portion, and the second invention is a peripheral edge of the lower end surface of the shaft portion. In addition, a plurality of ribs whose outer ends are inclined so as to face the opposite direction to the rotation direction are provided in a protruding manner.

[0005]

[Action]

 When the dough is kneaded by the rotary blade according to the first invention, the flange at the lower edge of the blade scoops the bread dough, so that the downward force acts on the blade and the rotary blade is prevented from coming out upward. To be done. When the bread dough is kneaded by the rotary blade according to the second aspect of the invention, the ribs at the lower end of the shaft portion eject the bread dough that tries to enter between the shaft portion and the bread container. Since neither the first device nor the second device has a rotary vane locking mechanism, the bread can be easily taken out from the bread container together with the rotary vane after baking the bread.

【Example】

 Next, an embodiment of the present invention will be described with reference to the drawings. FIG. 4 shows an automatic bread maker 1 having rotary blades 18 according to the present invention, a main body 2 includes a body 3, a chassis 4 attached to the bottom of the body 3, and an oven 5 housed therein. , A shoulder body 6 provided between the upper end of the oven 5 and the upper end of the body 3. A mounting base 7 is mounted on the chassis 4, and a drive shaft 8 extends through the mounting base 7 and is rotatably fitted therein. A bifurcated first engaging member 9 is attached to the upper end of the drive shaft 8, and a pulley 10 is attached to the lower end. Further, the thermistor 11 penetrates through the mounting base 7 and is pressed against the bottom of a bread container 15 described later to detect the temperature of the bread dough inside.

A kneading motor 12 is mounted on the chassis 4. The pulley 13 of the motor 12 and the pulley 10 of the drive shaft 8 are connected via a belt 14 so that the drive shaft 8 can be rotationally driven. The bread container 15 housed in the oven 5 is a rectangular container, and a supporting table 16 is attached to the outer surface of the bottom. A rotation shaft 17 that penetrates the bottom of the bread container 15 and projects into the bread container 15 is rotatably fitted to the support base 16. A rotary blade 18 according to the present invention is integrally and rotatably and detachably fitted to an upper end of the rotary shaft 17, and a second engaging member is engaged with a first engaging member 9 of the drive shaft 8 at a lower end thereof. A mating member 19 is attached.

As shown in FIG. 1A, the rotary blade 18 is composed of a shaft portion 20 and a blade portion 21. As shown in FIG. 3, the shaft portion 20 has a circular first shaft hole 22, a second circular shaft hole 23, and a step portion 24 formed at the boundary between the shaft holes 22 and 23. Has been done. The rotary shaft 17 is fitted in the second shaft hole 23 so as to be integrally rotatable, and the stepped portion 17a of the rotary shaft 17 is brought into contact with the stepped portion 24 for downward positioning. .. A flange 25 is provided so as to project from the lower end of the shaft portion 20, and the outer end of the flange 25 is oriented in the opposite direction to the rotation direction R, as shown in FIG. A plurality of inclined ribs 26 are provided so as to project at predetermined intervals. The blade portion 21 extends from the shaft portion 20 in a direction perpendicular to the rotary shaft 17, as shown in FIG. As shown in FIG. 1C, a flange 27 that inclines obliquely downward in the rotation direction R is provided at the lower end edge of the blade portion 21, and the inclined surface 28 on the upper surface of the flange 27 is the above-mentioned. It is continuous with the collar 25 of the shaft portion 20.

As shown in FIG. 2, ribs 15a and 15b are formed on the inner surfaces of the bread container 15 that face each other by pushing the side walls inward. As shown in FIG. 2, these ribs 15a and 15b are formed in positions displaced from each other in the opposite directions with respect to the center line so that the dough can be kneaded efficiently. In addition, 29 is a handle and 30 is a bread container fixing metal fitting for preventing the shake of the bread container 15 by coming into contact with the upper end of the bread container 15. A sheathed heater 31 for baking the bread dough is arranged in the oven 5 so as to surround the bread container 15. A heat shield plate 32 is provided outside the oven 5 with a heat insulating space therebetween. An operation display panel 33 is provided on the front surface of the shoulder body 6. A lid 34 that covers the upper opening of the oven 5 is openably and closably attached to the shoulder body 6.

In the automatic bread maker having the above structure, when the bread material is put into the bread container 15 and the kneading motor 12 is driven, the drive shaft 8 is driven via the belt 14, and the first drive shaft 8 is driven. At the same time that the engaging member 9 engages with the second engaging member 19 of the rotary shaft 17 to rotate the rotary shaft 17, the rotary blade 18 rotates. As a result, the bread dough in the bread container 15 is kneaded.

During this kneading process, as shown in FIG. 1C, the inclined surface 28 of the flange 27 provided on the lower edge of the blade portion 21 of the rotary blade 18 scoops up the bread dough P, so that the blade portion 21 faces downward. Force of. This prevents the rotary vane 18 from slipping upward. In addition, as shown in FIG. 1B, the bread dough P that is about to enter the gap between the lower end surface of the shaft portion 20 of the rotary blade 18 and the bread container 15 is a rib provided on the lower end surface of the shaft portion 20. It is pushed out to the side surface 26a of 26 and discharged. As a result, the bread dough P does not enter the lower end surface of the shaft portion 20 of the rotary blade 18 and a force to lift the rotary blade 18 does not occur, so that the rotary blade 18 is prevented from coming off.

When the kneading of the dough is completed, the dough is baked through fermentation and degassing. When taking out the baked bread from the bread container 15, the rotary blade 18 is only fitted to the rotary shaft 17 and there is no lock mechanism. 18 can be easily removed from the rotary shaft 17 together with the pan.
