Abstract

PURPOSE: To obtain an automatic baking device in which dough does not follow the motion of a kneading blade by shaping the kneading blade disposed at the bottom of a bread case put in an oven chamber to make a fan-shaped form and forming a plurality of corrugated protrusions and recessions at the ridge line. CONSTITUTION: Protrusions 37 and recessions 38 are formed at the ridge line of a kneading blade 36 disposed at the bottom of a bread case 8. Regarding the blade axis 39 suspended down, the clearance between the container bottom and the blade is gradually widened as it goes form the center to the outside in order to position the central bottom of the kneading blade more closely to the container bottom and prevent the blade from touching the container owing to the deflected motion of the blade. In the automatic baking device having such a constitution, a favorable dough can be provided because the dough made round by kneading it to a certain extent is kneaded so as to be caught because of the corrugated ridge line of the blade.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an automatic bread maker, particularly to the shape of the kneading blades of a kneading device.

[Conventional technology]

Figure 4 is a sectional view showing a conventional automatic bread maker. In Figure 2, (1) is the main body case, and (2) is the main body case (1).
), and the oven chamber (6) equipped around the entire outer circumference of the motor (3), heater (41, and heat shield plate (5)) is fixed. (8) is the oven chamber (6).
A rectangular parallelepiped bread case that is removably attached inside and equipped with a kneading blade (7), (9) is a belt for transmitting the power from the motor (3) to the kneading blade (7), and the dog Boo +7
(I[I.

It is decelerated and driven by the small pulley fi11. The static part is a handle attached to the top of the bread case (8), and the α3 is a support constructed on both sides of the oven chamber, and the fixed stand I fixed to the chassis (2) holds the entire bread case (8). There is.

The port 9 is a connector rotatably installed at the bottom of the oven chamber (6) and is linked to the large pulley α via a bearing Afiei. The rotational force is applied to the αnFi connector α by the kneading blade (7
) is rotatably supported by a bearing 1ull. This shaft! There is a kneading blade (
7) is removably equipped. +19 is a switch, and when the bread case (8) is set, the switch lever (2) is pressed by the bottom of the bread case (8) and turns on.

Ca1l is fixed to the oven chamber (6) with screws using an insulator C supporting the tip of the heater (4) and an insulator DC23 supporting the rear end. 3 is a temperature sensor which is pressed against the bread case (8) by a spring Q4.

θ is a fan constructed above the motor (3), which is covered by a fan cover (2) and configured to discharge heat from the motor (3) to the outside. In other words, it is an upper lid that covers the upper part of the main body case (1), and constitutes a reflector plate that covers the upper part of the oven chamber (6) and a heating plate @. ■ is the yeast container C3 with the solenoid installed between the top lid @ and the heat shield ■.
This is to open the shutter rock that closes the bottom of υ. (to) a cover that covers the top of the yeast container eI);
( is a control unit that controls bread baking, and e is a transmission unit that opens and closes the shutter ■ by the operation of the solenoid ■ using the lever E that is linked to the 9H solenoid ■.

Next, the operation will be explained. With the above configuration, ingredients other than yeast (flour and water) are put into the bread case (8) and the top lid is closed. Next, open the yeast container completely, add yeast, and start operation.

Motor (3) rotates upward, 9 ports, 9 small pulleys, belt (9),
The rotational force is transmitted to the kneading blades (7) in the bread case (8) through the large IJ (11), and the ingredients in the bread case (8) are kneaded.

During the process, the solenoid (■) operates to drop the yeast Wl from the yeast container 01+, and the kneading wheel further forms bread dough. Gas is vented during the process, and finally the heater (4) is energized and the temperature is controlled by the temperature sensor 4 to bake the bread. All of these are performed based on commands from the control unit [present], and bread baking is completed.

[Problem that the invention seeks to solve]

In conventional automatic bread makers, the shape of the kneading blade (7) is as shown in Figure 5, so when the flour and water are kneaded and become round, it follows the rotation of the kneading blade (7). There was a problem with this.

This invention was made to solve the above-mentioned problems, and its object is to provide an automatic bread maker in which the dough does not follow the movement of the kneading blades.

[Means for solving the gap]

In the automatic bread maker according to the present invention, the kneading blades provided at the bottom of a bread case provided in an oven chamber are fan-shaped, and a plurality of wavy uneven portions are provided on the ridgeline portion.

[Effect]

The automatic bread maker according to the present invention kneads the bread dough so that the concave and convex portions of the ridges of the kneading blade catch the dough.

[Embodiments of the invention]

An embodiment of the present invention will be described below with respect to the differences from the conventional automatic bread maker shown in FIG. 4.

In Figures 1, 2, and 3, (to) is a kneading blade,
The forehead is a convex part formed on the ridgeline of this feather (to), and the (to) is a concave part. c (!1 is a downward hanging part to bring the center bottom of the kneading blade closer to the bottom of the container, and gradually widens the gap between the bottom of the container and the blade outward from the center. This prevents collision between the container and the container.

In the automatic bread maker configured as described above, even if the protrusions and recesses formed on the ridges of the kneading blades knead to some extent and become round, the dough is caught in the kneading process.

〔Effect of the invention〕

As described above, according to the present invention, the ridges of the kneading blades are made uneven, so that the bread dough that has been kneaded to a degree that is rounded can be kneaded as if caught in a ball.

Test results have shown that it is possible to provide 6 excellent bread doughs, and 7 can be achieved by providing highly practical products.

[Brief Description of the Drawings] Figure 91 is a sectional view showing one embodiment of the present invention, Figure 2 is a perspective view of the kneading blade shown in Figure 1, and Figure 3 is a diagram showing the bottom of the container and the kneading blade shown in Figure 91. Showing the gap, Partial side view, No. 4
The figure is a sectional view of a conventional automatic bread maker, and FIG. 5 is a kneading blade of the conventional automatic bread maker. In the figure, (3) is the motor, (4) is the heater, and (6)
