DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a bread making machine having a kneading function.

Conventional technology When baking bread at home, generally a kneading machine,
Equipment such as fermenters, rolling pins, ovens, etc. are used, but it is difficult to control the temperature and time, and the conventional technology for baking bread by automating this to some extent is to automatically bake bread by setting a timer as shown in Figure 4. A fully automatic bread maker (Japanese Unexamined Patent Publication No. 56-3082), which can bake bread in a timely manner, is being considered. This configuration is shown in FIG. 4, where 1 is a main body case, 2 is a frame provided inside the main body case 1, and the frame 2 is equipped with a motor 3, a heating tank equipped with a heater 4 and a heat insulating material 5 on the outer periphery. 6 is fixed, a bread mold 8 having kneading blades 7 is installed in the heating tank 6, and a belt 14 and a pulley 1
It is decelerated and driven by 5. Further, a top plate 9 and a lid 11 having steam holes 10 are fitted to the heating tank 6, so that the heating tank 6 and the bread mold 8 are substantially sealed. 1
2 is a timer, temperature control, and voltage control circuit. Further, the temperature sensor 13 is fixed to the outer surface of the heating tank 6. With this configuration, when ingredients are put into the bread mold 8 and the timer is set, operation starts at a predetermined time, each process is automated by the timer and temperature control, and the bread is baked at the predetermined time.

Various shapes of kneading blades 7 have been considered, but in general, the kneading blades 7 are rotatable wing-shaped blades made of metal such as aluminum coated with fluorine and detachable from the rotating shaft. many. but,
To solve the problem of leaving large marks from the blades on the bottom of the finished bread, as shown in FIG. It has been considered that a wing shaft 7-c penetrating through the wing shaft 7-c pivotally supports the wing section 7-b at both ends, and is capable of rotating by a predetermined angle (in the direction of the arrow) and overturning.

Problems to be Solved by the Invention In such a conventional configuration, bread is automatically baked by adding ingredients and setting a timer, but since it is fully automated, kneading, fermentation, degassing, and baking are completely automated. Because both of these processes are carried out in the same container, as mentioned above, the kneading blades leave large marks on the bottom of the bread, or the blades become embedded in the bread, making it extremely difficult to handle. For this reason, a kneading blade with the configuration shown in Figure 5 was devised, and before the final fermentation, the kneading blade was reversed and the wing part of the blade was laid down horizontally, thereby eliminating the traces of the kneading blade on the bottom of the bread. As the part rotates, the coating may peel off due to the boss part, or it may turn into powder and stick inside the bread. Furthermore, since the boss part functions as a stopper for the wing part, there have been cases where the problem of peeling occurs in this part as well.

Means for Solving the Problems In order to solve these problems, the present invention attaches heat-resistant resin bearing parts to both sides of the boss part that pivotally supports the wing part, and slides with the wing part at this part. Furthermore, this bearing portion also serves as a stopper.

Operation With the above configuration, when the motor rotates forward during kneading and the kneading blade rotates forward, the wing part of the kneading blade rotates and rises due to the rotational force and the resistance force of the bread dough, and the dough is moved between the container and the dough. I will elaborate on it. When the motor is reversed, the blades of the kneading blades fall down, and by baking bread in this state,
There are almost no feather marks left on the bottom of the bread. Furthermore, since the boss portion and the wing portion are heated to high temperatures, metal such as aluminum coated with fluorine is used. Therefore, by inserting heat-resistant resin bearings on both sides of the boss part and at the same time forming a stopper part for the rotation of the wing part, the metals will rub against each other, the fluorine coating will peel off, and the bread will stick to it and become difficult to remove. It has the effect of preventing it from becoming dirty or becoming impossible to wash. It also prevents metal parts from making a loud noise when they rub or touch each other.

Embodiment Hereinafter, an embodiment of the present invention will be described in FIGS. 1 to 3.
This will be explained based on the diagram. In FIG. 1, 20 is a main body, 21 is a chassis provided within the main body 20, and a motor 22 is fixed to this chassis 21. A fan 23 and a small pulley 24 are fixed to the shaft of the motor 22, and power is transmitted to a large pulley 26 via a belt 25. Furthermore, a firing chamber 30 having a lower heater 27 provided at the inner bottom is fixed to the chassis 21. This firing chamber 30
Inside there is a bread baking mold 31 having a removable kneading blade 32 on the inner bottom, and a blade shaft 34 and an upper connector 37 are pivotally supported on a bread mold stand 35 fixed to the bottom of the bread baking mold 31. Further, the bread baking mold 31 is fixed to the chassis 21, and the large pulley 26
The pulley shaft 39 and the pulley base 40 that pivotally support the lower connector 38 are removably fitted together. Also,
An elastically supported temperature sensing portion 49 protrudes from the side surface of the baking chamber 30 and is in pressure contact with the side surface of the baking mold 31 . Further, an upper heater 41 is disposed on the inside of the upper part of the firing chamber 30 almost all around the circumference. Further, on the upper surface of the firing chamber 30, there is provided a lid 42 which can be opened and closed freely, and an inner lid 43 which is elastically supported by a mounting shaft 44 protruding from the center of the lower surface of the lid 42 and a presser spring 45.
By closing the lid body 42, the inner lid 43
The lower surface of the outer periphery is in pressure contact with the upper heater 41. Further, the lid body 42 is provided with an opening knob 47 and a latch 48 for opening the lid body 42. In addition, a pin shaft 56 is provided on the small pulley 24 side of the motor shaft at a position slightly eccentric to the motor axis, and a reciprocating pump 54 configured to vibrate an elastic membrane suction cup made of rubber or the like is attached to the side of the chassis 21.

and add flour and other ingredients. Lid body 42
, fill the water tank 52 with a predetermined amount of water, and close the cap (not shown) to seal it. In this state, the baking time of the bread is input from the switch panel, and when the predetermined time comes, the motor 22 starts operating and kneading is performed. At this time, the rotation of the motor 22 causes the reciprocating pump 54 to forcefully send air to the water tank 52, and this force injects water into the baking mold 31, where it is mixed with ingredients such as flour by the kneading blades 32. Then, kneading continued for a while,
Based on the information on the operating time of the temperature detection unit 49 and the motor 22, the operation of kneading is stopped, and each process of primary fermentation, degassing, molding fermentation, and baking is automatically performed at the set time. Bread is baked. Further, when the kneading blades 32 rotate forward, the wing portions 32-b rise up due to the resistance of the dough, stop at a predetermined angle, and rotate while the wing portions 32-b remain upright, thereby making it possible to knead the dough. can. Then, after the final degassing is completed, the blade part 32-b falls horizontally by reversing the motor 22, and if molding, fermentation, and baking are performed in this state, almost no blade marks will remain on the bottom of the bread. be.

In addition, as shown in Figures 2 and 3, the kneading blade 3
The boss portion 32-a of No. 2 has a bearing portion 32-a made of heat-resistant resin.
d is inserted, and since the wing portion 32-b slides and rotates on this side, there is no fear that the fluorine or coating will be removed.
Since the -f part constitutes a stopper and the wing part 32-b comes into contact with it, the coating may be peeled off as well.
This prevents metal objects from hitting each other and making noise.

Effects of the Invention As described above, according to the present invention, it is possible to make bread with a good appearance without leaving any traces of the kneading blades on the bottom or inside of the bread by making the blades of the kneading blades movable and rotating the motor in the forward and reverse directions. In addition, a heat-resistant resin bearing is installed on the side of the boss to prevent metals from rubbing or touching each other, thereby preventing the fluorine coating from peeling off and preventing the bread from adhering to the kneading blades, etc. Quiet kneading is possible with no contact noise between comrades.
