Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to an automatic bread maker that can automatically make bread at home simply by setting bread ingredients.

BACKGROUND OF THE INVENTION Conventionally, the kneading blades of this type of automatic bread making machine have been constructed as shown in FIG. That is, the kneaded feather 101
A fan-shaped wing section 103 about an axis 102 is capable of standing up and rotating at a predetermined angle from an almost horizontal lying state, and the standing portion 105 of the wing section 103 hits the boss section 104, changing the upright rotation angle. It is regulated. Even if the wing part 103 is in a collapsed state before the rotation of the kneading blade 1o1 starts, the wing part 10
3 stands up and rotates at a predetermined angle while standing up. In this state, the kneading blades 101 act as a large resistance to the bread dough, and a large kneading effect can be obtained. In addition, when the kneading process is completed and the degassing process is performed after the fermentation process, the motor is reversed, and the filling part 103 is laid down due to the resistance of the bread dough and baked, so that no traces of the kneading blades 101 remain on the bread. There is.

Problems to be Solved by the Invention However, with this conventional kneading blade configuration, in the case of bread dough that does not produce gluten, such as rye bread, the dough becomes mud-like. t
l-Shows behavior like kneading. The dough is highly sticky and sticks strongly to the inner wall of the bread mold, stopping the movement of the dough.Also, unlike wheat dough, which has strong connections between the dough due to the action of gluten, the structure of the dough is weak and the dough does not move easily. Since the connection between the dough is weak, the dough is not rolled up by the kneading blades 101 and tangled in a spherical shape.As a result, the rotation space of the dough kneading blades 101 becomes a hollow state with no dough. There was a problem in that the blade 101 rotated idly and the dough moved poorly, making it impossible to knead the entire dough.

The present invention solves these problems, and aims to provide an automatic bread making machine equipped with kneading blades that can knead bread dough regardless of the bread raw materials or the condition of the dough. It is something.

Means for Solving the Problems In order to solve the above-mentioned problems, the present invention provides a wing portion of the mixing blade that protrudes in the direction of the opening of the bread mold in the same direction as the rotation axis of the mixing blade when the mixing blade is collapsed. An arm portion is formed.

Effect By having the above structure, when the kneading blade is lowered, the arm part provided on the wing part of the kneading blade rotates along the inner wall of the bread baking mold, so that the bread dough adhering to the inner wall of the bread baking mold is scraped off. The entire dough is moved, and when the kneading blades are in an upright state, the arm is positioned above the center of the dough, so it kneads the center of the dough together with the wing parts of the kneading blades.And by repeating forward and reverse rotation of the motor,
By rotating the kneading blades while repeating the lowering and raising of the kneading blades, the bread dough can be kneaded uniformly.

7, and a wing portion 19 that is rotatably supported by the boss portion 17 via a shaft 18. The range of upright rotation of the wing section 19 is regulated by abutting portions 20 of the wing section 19 against the boss section 17. The shaft 18 passes through the boss portion 17 at a substantially right angle to the rotational axis direction of the boss portion 17, and pivotally supports the wing portion 19 at both ends thereof. Further, an arm portion 21 is provided at the outer peripheral end of the wing portion 19 and projects toward the opening of the baking mold 13 in the same direction as the rotation axis of the kneading blade 12 when the kneading blade 12 is folded down. The bread baking mold 13 is fixed to the chassis 2, and is removably fitted to a baking tray 22.

The breadboard stand 22 pivotally supports a pulley shaft 24 to which a large pulley 7 and a lower connector 23 are attached. Further, an elastically supported temperature sensing portion 26 protrudes from the side surface of the inside of the baking chamber 1o, and is in pressure contact with the bread baking mold 13. In addition, the upper surface of the firing chamber 1° has a lid 2 that can be opened and closed freely.
6 and an inner lid 27 provided on the lower surface of this lid body 26 can seal the lid. The above-mentioned components, especially the baking chamber 10° bread baking mold 13, kneading blade 12, etc., mainly constitute the cross-wire and baking device. moreover,
A solenoid 30 is installed in the lid 26 to open and close the valve 29 of the yeast container 28, which is fixed to the inner lid 27 and supported by the lid 26, and to drop the yeast.

This is a control device that controls all of the motor 3, heater 8, solenoid 30, etc. based on the input information of 6. According to the control conditions by this control device 32, everything from crosstalk to firing is automatically performed.

Next, the operation of this embodiment will be explained.

First, in FIG. 2, the kneading blade 12 has a wing section 19 centered around the shaft 18, which can be rotated upright at a predetermined angle from an almost horizontally laid down state, and the boss section 17 has a section 2o that abuts the wing section 190.
If you want to bake bread at a certain predetermined time, put ingredients other than yeast such as flour and water into the bread baking mold 13, and then press the baking mold 13. into the baking chamber 10 and close the lid 2.
6 is closed, and a predetermined amount of yeast is put into the yeast container 28. Then, when the power is turned on and the baking time is input from the switch spring/I/31, the baking starts automatically at the predetermined time. First, by the forward rotation of the motor 3, the kneading blades 12
rotates and the ingredients in the bread baking mold 13 are kneaded. The same applies to the condition), the tool part 19 moves to the second
Stand up as shown by the dashed line in the figure, and press the tool part 19 at a predetermined angle.
rotates while standing up. At this time, arm portion 21
Since it is located at the upper center of the bread dough, it is possible to knead the part that is lifted above the rotation space of the wing section 19 and cannot be covered by the wing section 19. This operation causes the kneading blades 12 to act as a large resistance to the bread dough, resulting in a large kneading effect. Further, when the motor 3 is rotated in the reverse direction, the kneading blades 12 bring the wing portions 19 from the upright state into a fully collapsed state due to the resistance of the reversely rotated levain dough (the same applies even in the flour state). At this time, the arm part 21 rotates near the inner wall of the bread baking mold 13, removing the bread dough adhering to the inner wall of the bread baking mold 130 and moving the entire bread dough. It can be kneaded evenly throughout. When the kneading is completed, the fermentation process begins, but the motor 3f is not rotated during this fermentation process. During the degassing step after this fermentation step, the kneading blades 12 are rotated to remove a portion of the gas generated by yeast fermentation in the bread dough. At the end of this degassing step, the motor 3 is rotated in the reverse direction to keep the wing section 19 in a laid down state. After the above steps, baking is performed and the bread is baked, but at this time, since the filling part 19 is lying down, there are fewer traces of the kneading blades 12 left on the bread.

The kneading blade 12 shown in FIG. 3 differs from the kneading blade 12 shown in FIG. 2 in that the front outer peripheral corner portion 33 of the arm portion 21 in the normal rotation direction is sloped.

In this way, the front outer peripheral corner portion 3 of the arm portion 21 in the forward rotation direction is
3, when the kneading blades 12 are rotated forward, the wing portions 19 stand up due to the resistance of the dough (even in the flour state), and when the wing portions 19 rotate at a predetermined angle in the upright state, this The arm portion 21 receives the resistance force of the dough so as to assist the riser of the wing portion 19. The kneading blades 12 shown in FIG. It differs from the kneading blade 12 shown in FIG. 2 in that it is provided.

In this way, the rear inner circumferential corner portion 3 in the forward rotation direction of the arm portion 21
4 is provided with an inclination, so that when the wing part 19 rotates in a collapsed state due to the resistance force of the bread dough (the same applies even in the flour state) when the kneading blade 12 rotates in the reverse direction, this arm part 21 helps the wing part 19 to lie down. It receives the resistance force of the bread dough and at the same time brings the dough to the center of the baking mold 13.

The kneading blade 12 shown in FIG. 6 is different from the kneading blade 12 shown in FIG.
It is different from This is because when the kneading blades 12 rotate in the reverse direction and the wing parts 19 are rotated in a collapsed state, if the bread dough (even in the flour state) has an inclination on the rear end surface 36 of the arm part 21, it will heal to the inclined surface and the dough will move upward. The rear end face 36 is not sloped because the kneading performance is degraded by the pushing up. If the front end face 36 of the arm portion 21 in the forward rotation direction is sloped, the arm portion 21 will easily come off when the kneading blades 12 are taken out from the bread after baking.

The kneading blade 12 shown in FIG. 6 differs from the kneading blade 12 shown in FIG. 6 in that the upper end corner 37 of the front end face 36 of the arm portion 21 in the normal rotation direction is sloped. With the kneading blade 12 having such a configuration, when the kneading blade 12 is taken out from the bread after baking, the arm portion 21 will come off more easily, and it will not be possible to accidentally put the kneading blade 12 into the hand bread baking mold 13 while the kneading blade 12 is rotating. Even if the arm part 21 of the kneading blade 12 is touched, it is safe.

Effects of the Invention As is clear from the description of the above embodiments, according to the present invention,
The wing part of the kneading blade can be raised and lowered with respect to the boss part, and the wing part has an arm part that projects in the same direction as the rotation axis of the kneading blade in the direction of the opening of the bread mold when the kneading blade is folded down. Because of this, the excellent effect of being able to uniformly knead the entire bread dough can be obtained.
