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, generally a kneading machine, a fermentation machine, a stretching rod, an oven, etc. are used, but it is very difficult to control the temperature and time, so it is necessary to automate this to some extent. As a conventional technology for baking bread, various devices have been considered that can automatically bake bread by simply setting the baking time.
An example is shown in FIG. In other words, 1 is the main case, 2
is a chassis provided in the main body case 1, 3 is a motor,
4 is a heater, 6 is a firing chamber whose outer periphery is covered with a heat insulating material 5, and these motors 3. Heater 4. Firing chamber 6 is chassis 2
Fixed. A kneading container 8 having kneading blades 7 is detachably installed in the baking chamber 6.
The motor 3 drives the belt 9, pulley 10. Boo IJ1
1 to be rotated by deceleration drive. Above the firing chamber 6,
A lid body 13 having an inner lid 12 that can be opened and closed is provided, and a water supply bag @ 14 for supplying water into the kneading container 8 is also provided.

Furthermore, a temperature detector for detecting the temperature of the kneading container 8 and a motor 3. Heater 4. A control device 15 that controls the water supply device 14 and the like, and an input device (not shown) that sets control conditions for the control bag @15 are provided.

With this configuration, when ingredients other than the amount of water are put into the kneading container 8 and the baking time etc. are input from the input device, the water supply device 14 and the motor 3 start operating at a predetermined time, and the kneading container 8 is heated. The kneading process is performed while detecting the temperature, 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 and the baking process begins. This was done so that the bread would be baked at the 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 materials in the kneading container 8 are left as they are. There is no problem if you want to make bread immediately, but if you want to set it up 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, water is kept in a separate location, and water is supplied by the water supply device 14 at the same time as kneading begins. 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 temperature of the water will rise during the hot summer months, and the temperature of the dough will become too high during kneading, which will increase the activity of the yeast bacteria and make it impossible to make good bread. Also, during cold winters, the water temperature drops too low, and when water is supplied, the cold water hits the yeast and kills the yeast.
In this case as well, you will not be able to make good bread.

Furthermore, if the temperature is low, the water will freeze and you won't be able to make bread at all, so the water tank has an insulated structure to prevent the water temperature from dropping.

It was designed to be chilled by adding ice. Additionally, if you start kneading the dough with yeast in it while supplying water, fermentation will proceed from that point and 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 the bread will not be made properly. Conversely, if you control the kneading time so that the temperature of the bread dough is at the optimum temperature, the fermentation time will change each time, resulting in over-fermentation or under-fermentation, making it difficult to consistently produce bread. In addition, depending on the temperature of the dough at the beginning of kneading, the dough may be kneaded insufficiently or over-kneaded, resulting in problems such as failure to make bread properly. Therefore, another method of making bread is to put all ingredients other than yeast in a kneading container and preheat it first, let it rest for a certain period of time, and then add yeast only after the time required to bake the bread at the desired time has come. After putting it in and rehearsing it,
There is a method that involves the processes of fermentation and baking, and 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. Since it does not require any structure, it can be made compact, but in reality, no concrete structure has been thought of that would allow yeast to be automatically introduced into the kneading container.

(Means for Solving the Problems) In order to solve these 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 is provided at the lower part, and a yeast container is provided on the inner lid, the yeast container having an upper opening whose upper part opens to the upper surface of the lid and a lower opening located above the kneading container, An opening/closing plate for the opening of the yeast container is provided, which is integrally provided with a rotating shaft pivotally supported between the lower part of the yeast container and the upper surface of the inner lid, and presses into contact with the lower opening of the yeast container by the force of a spring. is bent at one end to form an L-shape, and the bent portion is rotated by a transmission plate driven by a drive device to open the opening/closing plate.

(Function) The lower opening of the yeast container provided in the inner lid is positioned above the kneading container, and the opening/closing plate that is pressed against this lower opening by the force of a spring is opened by the drive of the drive device. Since it is a kneading container, yeast can be put into the kneading container by automatically operating the drive device when necessary. Therefore, ingredients other than yeast, such as water and flour, are placed in a kneading container, the kneading blades are driven by a motor, and the dough is pre-mixed. Yeast is then added to the pre-mixed material for post-kneading. Insulated water tank.
