Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to an automatic bread maker that can be used to knead wheat flour and make bread at home.

(Conventional technology) Generally, when making bread, equipment such as a kneader, a fermenter, a rolling pin, and an oven are used, but it is very difficult to control the temperature and time, and it is difficult to bake delicious bread regardless of the time of the year. Making fresh bread required considerable skill. To solve this problem,
As shown in FIG. 2, an automatic bread maker has been proposed that has a kneading function, a fermentation function, and an oven function in a single product.

In the device shown in FIG. 2, a frame 2 is provided inside a main body 1, and a motor 3, a heating tank 6 with a heater 4 and a heat insulating material 5 provided on the outer periphery are fixed to the frame 2, and a kneading material is placed inside the heating tank 6. A kneading container 8 having blades 7 is detachably attached to the kneading container 8, and is decelerated by a belt 9 and a pulley 10. When the material in the kneading container 8 is put in and a timer 11 is set, the motor starts at a predetermined time. 3 is energized, the ingredients in the kneading container 8 are kneaded by the blades 7, and each step is automatically performed by the timer 11 and temperature control to bake the bread at a predetermined time.

(Problems to be Solved by the Invention) In such a conventional configuration, since the kneading container 8 is only attached to the heating tank 6, the reaction of the blades 7 during kneading is caused by the kneading container 8 and the heating tank 6. It will fall on the contact area. Usually, the heating tank 6 uses a thin metal plate to increase thermal efficiency, so the movement of the blades during kneading produces a sound of contact between the kneading container 8 and the heating tank 6. By the way, it's not an automatic bread maker,
Many conventional kneading machines have a kneading container and main body that are rotatably fitted together, such as bayonet or screw fitting, but automatic bread machines do not heat the kneading container immediately after baking at a very hot point. Because of the unloading operation, there was a problem that complicated operations could not be performed, and there was also the problem that the kneading process was often used at night and the sound of kneading in the middle of the night would wake you up.

In view of the above points, the present invention provides an automatic bread maker in which a kneading container can be attached with a simple operation and the noise during kneading is reduced.

(Means for Solving the Problems) Therefore, the present invention provides a firing container in which a connector rotated by a motor is provided, and a cylindrical guide that surrounds the connector is protruded from the bottom of the firing container, and the guide is housed in the firing container. The kneading container has a kneading blade inside which is connected to the connector and is rotated, and a double cylindrical protrusion is provided at the lower part of the kneading container to sandwich the inner and outer circumferential surfaces of the cylindrical guide. .

(Function) When installing the kneading container in the firing container, the double cylindrical protrusion of the kneading container only needs to be fitted into the cylindrical guide of the firing container, so the installation is extremely simple and easy. Since the double cylindrical projections of the kneading container are sandwiched and fitted into the cylindrical guide, the movement of the kneading container during kneading is regulated and the generation of noise is reduced.

0 is in pressure contact. 68 is a lid body that can be opened and closed;
A lid cover 67 to which an inner lid 66 is attached is provided above the firing container 44 . By closing the lid 68, a cooking chamber 69 is formed by the inner lid 66 and the baking container 44. A yeast container 65 having a container lid 62 that can be opened and closed is fixed to the inner lid 66. The yeast container 65 is equipped with a rotating shaft 64 to which an opening/closing plate 63 for opening and closing the bottom of the container 65 is fixed. When the driving device 59 is energized, the opening/closing plate 63 is opened by driving the transmission plate 61 rotatably supported on the shaft 60 and moving the rotating shaft 64 . 70 is a switch panel for inputting and setting cooking completion time, etc.; 71 is a switch panel 7;
This is a control device for determining and outputting control conditions for the motor 32, heater 48, etc. based on the input of 0 and the input information of the temperature detection section 50.

Next, the operation of the above device will be explained.

In the baking container 44, a kneading blade 53 is attached and a kneading container 55 containing ingredients other than yeast such as flour and water is set, the lid 68 is closed, and a predetermined amount of yeast is placed in the yeast container 65. .
In this state, input the bread completion time from the switch panel 70 and start the bread. At a predetermined time, the motor 32 starts operating, the small pulley 34 rotates, and the large pulley 37 and connector 38 rotate via the belt 39. The rotation of the connector 38 is directly transmitted to the container connector 52, and the kneading container 55
The inner kneading blade 53 is rotated to knead the material. Then, when a predetermined time comes, the drive device 59 inside the lid 68 is energized to drive the transmission plate 61, move the rotary shaft 64, open the opening/closing plate 63, and release the yeast contained in the yeast container 65. Kneading container 5
Insert within 5. After the yeast put into the kneading container 55 is kneaded with other materials for a predetermined time, the temperature of the kneading container 55 is adjusted by the heater 48 while inputting information from the temperature detection section 50 based on the process control of the controller 71. The bread is baked at the set time by automatically performing the primary fermentation, degassing, molding fermentation, and baking steps while adjusting the temperature.

During kneading in the above process, the kneading container 55 moves in a complicated manner due to the reaction of the kneading blades 53 transmitted and driven from the connector 38 kneading the material in the kneading container 55. At this time, since the cylindrical guide 43 is sandwiched between the inner cylindrical projection 72 and the outer cylindrical projection 73 provided at the lower part of the kneading container 55,
When the kneading container 55 is simply fitted with the outer circumference of the inner cylindrical projection 72 and the inner circumferential surface of the cylindrical guide 43, the movement of the kneading container 55 to fall diagonally during kneading can be reduced. Furthermore, by forming the upper end of the outer periphery of the cylindrical guide 43 and the lower end of the inner periphery of the outer cylindrical projection 73 of the kneading container 55 into inclined surfaces that coincide with each other, centering becomes accurate and installation becomes easier. .

(Effects of the Invention) As described above, according to the present invention, the double cylindrical protrusions at the bottom of the kneading container are fitted so as to sandwich the inner and outer peripheral surfaces of the cylindrical guide at the bottom of the baking container. The movement of the kneading container when kneading materials with the blades can be reduced to reduce noise, and the kneading container can be placed in the firing container extremely easily by simply placing it on the cylindrical guide so that the double cylindrical protrusion fits. I can do it.
