Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an automatic bread maker that can produce freshly baked bread at a desired time simply by adding predetermined ingredients.

(Conventional technology) When baking bread at home, we generally use a kneading machine, fermentation machine, stretching rod, oven, etc., but it is very difficult to control temperature and time, so it is necessary to automate this to some extent. As a conventional technique for baking bread, various devices have been considered that automatically bake bread simply by setting the baking time, and an example thereof is shown in FIG. That is, 1 is a main body case, 2 is a chassis provided in the main body case 1, 3 is a motor, and 5
1 is a heater, and 6 is a firing chamber whose outer periphery is covered with a heat insulating material 5. These motor 3, heater 4, and firing chamber 6 are fixed to the chassis 2. Inside the firing chamber 6,
A kneading container 8 having a kneading blade 7 is detachably attached to the kneading blade 7, and the kneading blade 7 is driven to rotate at a reduced speed by a motor 3 via a belt 9, a pulley 10, and a pulley 11. A lid 13 having an inner lid 12 that can be opened and closed is provided above the baking chamber 6, and a water supply device 14 for supplying water into the kneading container 8 is also provided. Furthermore, a temperature sensor that detects the temperature of the kneading container 8, a control device 15 that controls the motor 3, the heater 4, the water supply device 14, etc., and an input device (not shown) that sets the control conditions of the control device 15.
and is provided. With this structure, when materials other than water are put into the kneading container 8 and the baking time and other information are inputted from the input device, the water supply device 14 and the motor 3 start operating at a predetermined time.
The kneading process is performed while detecting the temperature of the kneading container 8, and when a predetermined temperature or a predetermined time is reached, the motor 3 is stopped and the fermentation process begins. In the fermentation process, the temperature is controlled by the heater 4 depending on the temperature of the kneading container 8, and the degassing operation is performed several times by the rotation of the motor 3. After a predetermined period of time, the heater 4 is energized. A baking process is performed so that the bread is baked at a desired time.

(Problems to be Solved by the Invention) In such a conventional method, in order to bake bread at a desired time, from the time the ingredients are placed in the kneading container 8 until the time required for actually making the bread arrives, The material contained in the kneading container 8 is left as is. There is no problem if you want to make bread immediately, but if you want to set it at night and bake it in the morning, for example, if you add moisture to the ingredients, the yeast will start fermenting before you knead them, and you won't be able to make bread at all. . Therefore, the water should be kept in a separate place, and the water supply device should be turned on as soon as kneading begins.
Water is supplied by 4. Therefore, the water supply device 14 consisting of a large water tank and a pump mechanism becomes an essential component, and the overall size of the bread maker increases. Also, if you leave water for a long time, the water temperature will rise during hot summers, so
If the temperature of the dough becomes too high during kneading, the activity of the yeast becomes too high, making it impossible to make good bread. Also, in cold winters, the temperature of the water drops too low, and when water is supplied, the cold water hits the yeast and kills the yeast, making it impossible to make good bread. Also, if the temperature is even lower, the water will freeze, making it impossible to make bread at all. Therefore, to prevent the water temperature from dropping, the water tank has an insulated structure or ice is added to cool it. Additionally, if you start kneading the dough with yeast in it while supplying water, fermentation will proceed from that point on and at the same time the temperature of the dough will rise as the dough is kneaded. Therefore, if you do not change the kneading time depending on the temperature of the dough at the beginning of kneading, the temperature of the dough will become too high or too low and you will not be able to make bread properly, or conversely, the temperature of the dough will not be adjusted to the optimum temperature. If you control the kneading time in this way, the fermentation time will change each time, resulting in over-fermentation or under-fermentation, making it impossible to consistently make bread, or depending on the temperature of the initial dough, the fermentation time may change. There were problems such as over-kneading and not being able to make bread properly. Therefore, another method of making bread is to pre-knead the ingredients other than the yeast in a kneading container, let it rest for a certain period of time, and then add the yeast after the required time to bake the bread at the desired time. There is a method that involves adding the ingredients, post-kneading, fermentation, and baking.If you use this method to automatically make bread, you will not have the problems mentioned above, and you will always be able to bake consistently good bread regardless of summer or winter. However, in reality, no concrete structure had been considered that would allow the yeast to be automatically introduced into the kneading container.

(Means for Solving the Problems) In order to solve the above problems, the present invention provides a lid body that can be opened and closed to cover a baking container that removably accommodates a kneading container that has kneading blades driven and rotated by a motor. An inner lid for sealing the baking container fixed to the yeast container is supported on the lower part of the lid so that it can slide up and down using the screw as a guide, and the lid and the yeast container are connected to each other. are brought into contact with each other through an elastic body, and the yeast container has an upper opening that opens on the upper surface of the lid and a lower opening that opens on the lower surface of the inner lid and is located above the kneading container, and This is provided with an opening/closing plate for the opening operated by a drive device.

(Function) The lower opening of the yeast container fixed on the inner lid is positioned above the kneading container, and this opening is opened and closed by an opening/closing plate operated by a drive device, so that it can be driven when necessary. It is now possible to operate the device and put yeast into the kneading container. Therefore, materials other than yeast such as water and flour are placed in the kneading container and kneaded by rotating the kneading blades using a motor drive. Since yeast can be added to the pre-kneaded ingredients for post-kneading, there is no need for a water tank, water supply device, or insulation structure, allowing the overall size to be reduced. Further, by opening the upper opening of the yeast container on the top surface of the lid, yeast can be put into the yeast container with the lid closed. Further, the inner lid to which the yeast container is fixed is supported by a mounting screw so that it can slide up and down using the mounting screw as a guide, and the lid and the yeast container are brought into contact with each other via an elastic body. As a result, even if there is some variation in dimensions, the elastic body works to tightly adhere to the baking container and reliably seal the container. In addition, by simply removing the mounting screws, you can take out the inner lid and clean the yeast container and the opening/closing part of the bottom opening.

It is a control device.

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

A kneading blade 53 is attached to the baking container 44, and a kneading container 55 containing materials other than yeast such as flour and water is set, and the lid is closed. At this time, the inner lid 66 comes into pressure contact with the firing container 44 due to the action of the elastic body 74, completely sealing the container 44. On the other hand, a predetermined amount of yeast bacteria 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. Connector 3
The rotation of 8 is directly transmitted to the container connector 52, and the kneading blades 53 in the kneading container 55 are rotated to knead the material. Then, when a predetermined time comes, the drive device 59 inside the lid 68 is energized and the transmission plate 6 is turned on.
1 is driven, the rotary shaft 64 is moved, the opening/closing plate 63 is opened, and the yeast stored in the yeast container 65 is thrown into the kneading container 55. 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 control device 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.

When cleaning the yeast container 65 and the opening/closing mechanism at the lower opening of the container 65, it is sufficient to remove the mounting screws 72 and remove the inner lid 66 from the lid cover 67.

(Effects of the Invention) As described above, according to the present invention, the yeast stored in the yeast container is automatically transferred to the kneading container when necessary by opening the opening/closing plate that closes the lower opening of the yeast container using a driving device. This means that ingredients other than yeast, such as water and flour, are pre-kneaded in a kneading container, and then yeast can be added to the dough for post-kneading. It is possible to make the whole bread smaller, and it is possible to knead the dough strongly even if the temperature rises a little during pre-kneading, which does not contain yeast, so it is possible to always obtain stable and good bread regardless of summer or winter. . Furthermore, since yeast can be added without opening the lid, it is easy to charge the yeast. Furthermore, the inner lid to which the yeast container is fixed is supported by a mounting screw with respect to the lid so that it can slide up and down using the screw as a guide, and the lid and the yeast container are brought into contact with each other via an elastic body. Even if there are slight variations in dimensions, the inner lid can always be brought into pressure contact with the firing container and the firing container can be kept in a completely airtight state. Therefore, the temperature inside the firing container can be stably controlled and the temperature can be maintained in a good condition. I can make bread. The inner lid can be removed from the lid body by simply removing the mounting screws, so the yeast container and the opening/closing mechanism at its lower opening can be cleaned.

In addition, a stopper is provided for the mounting screw on the inner lid to prevent it from falling or being lost, and the conical tip facilitates insertion into the screw hole on the lid side.
