Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an electric bread maker for home use that is capable of making bread on a timer similar to an electric rice cooker.

(Prior Art) In general, bread making at home can only be achieved successfully by using kneading machines, fermenters, rolling rods, ovens, etc., and by skillfully managing difficult temperature and time controls. This bread-making work, which requires skill,
In order to electrically automate the process like a rice cooker, an electric bread maker for home use as shown in FIG. 2 has been proposed.

In other words, Figure 2 shows the conventional electric bread making machine (hereinafter referred to as
1 is a cross-sectional view showing a bread making machine (simply referred to as a bread making machine), and 1 is a main body case having a chassis 2 inside, to which are fixed a motor 3, a heater 4, and a baking chamber 6 having a heat insulating material 5 arranged around its outer periphery. A kneading container 8 having kneading blades 7 is removably attached to this baking chamber 6.
The belt 9 and pulley 1 are driven by the motor 3.
The kneading blade 7 rotates at a reduced speed via the rotation speeds 0 and 11. Furthermore, a lid 13 having an inner lid 12 is formed in the baking chamber 6 so as to be openable and closable, and a water supply device 14 for feeding the kneading container 8 is further provided.

Reference numeral 15 denotes a temperature detection section for detecting the temperature of the kneading container 8, and 16 denotes a control device for controlling the motor 3, heater 4, water supply device 14, etc., and the control conditions are set through an input device (not shown).

In the conventional bread making machine configured in this way, when the bread ingredients except water are put into the kneading container 8 and the desired baking time and control conditions are inputted from the input device (not shown), the desired baking time and control conditions are input. At a predetermined time, the operation of the water supply device 14 and the motor 3 is started according to a timer, and the kneading process proceeds while the temperature of the kneading container 8 is detected by the temperature detection section 15, and the temperature reaches the predetermined temperature. At a predetermined time, the motor 3 is stopped and the fermentation process begins. In the fermentation process, the temperature is controlled by the heater 4 according to the temperature of the kneading container 8, and the degassing process by the rotation of the motor 3 is repeated to advance fermentation, and after a predetermined period of time, the heater 4 is energized. The baking process begins, and bread making is completed after a predetermined period of time.

(Problems to be Solved by the Invention) In such a conventional bread making machine, in order to bake at a desired time, the ingredients are placed in the kneading container 8 from the time the ingredients are put into the kneading container 8 until the bread making actually begins. Therefore, for example, if you set the baking time to bake the next morning and supply water to the ingredients the night before, yeast fermentation will begin before the kneading process begins, and the baking process will begin. becomes completely impossible. For this reason, a separate water supply device 14 is provided to supply water at the same time as the kneading process begins, but this requires a large water tank and a water supply drive device, which inevitably increases the size of the entire bread making machine. It's summery. In addition, if a separate water supply device 14 is provided in this way, the water temperature increases in the summer, so the water supply temperature during the kneading process is high, which increases the activity of the yeast too much, making it impossible to make satisfactory bread. In some cases, the activity of the yeast weakens, and in some cases, the yeast dies, making it impossible to make bread, or in extreme cases, the water dispenser 14 freezes.
It was necessary to take measures such as creating an insulated structure for the engine and adopting a cooling system in the summer.

Additionally, if you start the kneading process with yeast added, the temperature of the dough will rise at the same time as fermentation begins, so the kneading process time must be adjusted depending on the temperature at the beginning of kneading the pin dough. In some cases, the temperature of the bread dough rises too high or becomes too low, which may lead to failure in bread making. Conversely, if you control the kneading start time so that the dough temperature is the optimum temperature, the fermentation time will change each time, so in this case as well, there is a risk of over-fermentation or under-fermentation and failure of bread-making. It was hot.

To prevent the above drawbacks and failures, kneading container 8
Bread ingredients other than yeast are added to the pan and pre-kneaded first, and after a certain amount of time has elapsed, that is, after a certain amount of time has passed, yeast is added at the time required to bake the bread at the desired time and post-kneading is performed. conduct,
It has been proposed to make bread through the processes of fermentation and baking, but according to this method, stable bread making is possible without a water supply device 14 or an insulated structure, but in reality, automatic injection of yeast is not possible. The reliable specific configuration of the device had not been resolved.

The yeast is introduced by letting it fall naturally from directly above the baking chamber 6 in which the kneading container 8 is installed, but in order to do so, the yeast container is placed above the baking chamber 6, and the yeast is then poured into the kneading container 8.
An opening/closing mechanism for the yeast container and its driving device are required to drop the yeast into the yeast container.

It is desirable to install the above-mentioned drive device above the baking chamber 6 in the same way as the yeast container, but problems such as rust or deterioration of insulation may occur due to the influence of steam emitted during bread baking, so the drive device should not be installed during baking. It is installed in the lid body 13 isolated from the chamber 6, and its driving force must be transmitted to the opening/closing plate via a transmission plate. Similarly, there are problems such as rust and poor insulation.

(Means for Solving the Problems) The present invention particularly solves the problems of rust and insulation deterioration of the drive device in the conventional bread making machine described above, by providing a kneading container having a rotationally driven kneading blade therein. In an electric bread maker that is removably installed in a baking chamber, a yeast container is provided with a lower opening located above the kneading container, and an opening/closing plate is disposed in the lower opening of the yeast container so as to be openable and closable. This solution is achieved by installing a drive device for opening and closing this opening/closing plate via a transmission plate inside the main body case, avoiding a position directly above the kneading container.

(Function) With the above configuration, the present invention does not configure the drive device directly above the firing chamber, so it is difficult for the heat and steam generated during firing to enter the drive device side, resulting in rust, insulation deterioration, etc. Most of the occurrences are prevented, and an electric bread maker with fewer failures can be obtained.

(Example) Hereinafter, the present invention will be explained in detail using examples.

FIG. 1 is a sectional view showing an electric bread maker according to an embodiment of the present invention. is fixed to one end of the shaft, a cooling fan 33 for the motor 32 itself is fixed to the other end, and a small pulley 34 is fixed to the other end.
A fan guide 35 is fixed around the cooling fan 33 to increase cooling efficiency. Further, a large pulley 37 is rotatably supported on the chassis 31 via a bearing 36, a connector 38 is fixed to the opposite shaft end, and the small pulley 34 and large pulley 37 are rotatable via a belt 39. combined.

Further, a switch lever 40 is rotatably supported on the chassis 31 around a shaft 41, and a switch 42 is attached to the upper part of one end of the switch lever 40, and a cylindrical guide 43, a baking container 44 and a heat shield plate 45 covering the surroundings thereof are fixed. Furthermore, a heater 48 is fixed to the wall surface of the firing container 44 via an insulator 46 by a stopper 47, a container fixing spring 49, and an elastically supported temperature detecting section 50. In addition, a kneading container 55 has a container connector 52 fixed to one side through a bearing 51 on the inner bottom, and a blade shaft 54 to which a kneading blade 53 can be detachably attached to the other side is pivotally supported. 49, and is removably fitted and mounted. When the kneading container 55 is mounted, it is mounted in pressure contact with the temperature detection section 50, and a handle 56 is attached to the upper end. Further, the upper part of the firing container 44 is fixed to a fixing member 57, and the upper frame 58 of the main body 30 is fixed not only to the fixing member 57 but also to the chassis 31.

Inside the horizontal upper surface of the baking container 44, a drive force transmission plate 61 for an opening/closing plate 63 rotatably supported by a drive device 59 and a shaft 60 is provided, and the yeast container lid 62 can be opened and closed. A yeast container 65 is equipped with a rotary shaft 64 to which an opening/closing plate 63 which can be opened and closed is fixed, and a lid body 68 is formed with a lid cover 67 to which an inner lid 66 of the main body 30 is attached. Further, 68-a is a partition wall for separating the installation position of the yeast container 65 and the installation position of the drive device 59.

By closing the lid 68, a firing chamber 69 is formed by the inner lid 66 and the firing container 44, and the isolation 68
-a is formed at a position that separates the lid portion directly above the firing chamber 69 from the other portions.
70 is a switch panel for inputting settings such as the baking time, and 71 is a switch panel for controlling the motor 32 and the heater 48 based on the input and information input from the temperature detection section 50.
This is a control device for determining and outputting control conditions such as

The electric bread maker of the present invention configured as described above has the following features:
First, a kneading container 55 is equipped with a kneading blade 53 and contains bread making ingredients such as flour and water from which yeast has been removed.
is set in the firing container 44 and the lid 68 is closed.
A predetermined amount of yeast is put into the yeast container 65, and in this state, the baking time of the bread is set using the switch panel 70.

As a result, when a certain predetermined period of time has elapsed, the motor 32 rotates the connector 38 via the drive system of the pulley 34, belt 39, and large pulley 37, thereby driving the container connector 52 to mix the dough in the kneading container 55. The blade 53 is rotated to knead the bread making ingredients. Furthermore, after a predetermined period of time, the drive device 59 inside the lid 68 is energized, and the transmission plate 61
is driven horizontally, thereby operating the rotating shaft 64 and opening the opening/closing plate 63, causing the yeast in the yeast container 65 to fall and be thrown into the kneading container 55, where the yeast is mixed and kneaded with other ingredients for a predetermined time. It will be done. Thereafter, based on the process control of the control device 71, the heater 48 adjusts the temperature of the kneading container 55 based on the detection information of the temperature detection unit 50, and automatically performs each process such as primary fermentation, degassing, molding fermentation, and baking. The bread will then be baked at the set time.

Hereinafter, the present invention has been explained in detail with reference to an embodiment, but the present invention is particularly advantageous in that the driving device 59 is configured by removing the portion directly above the baking chamber and separating it from the yeast container portion by a partition wall, so that the steam generated during bread baking The problem is solved by preventing exposure to

(Effects of the Invention) As is clear from the above detailed explanation, the present invention is capable of producing bread dough by dropping yeast on a water-containing material other than the previously kneaded yeast and kneading the yeast. In particular, since simultaneous kneading eliminates the need for a water supply device including a water supply tank or an insulating structure, it can be configured in a smaller size, and the ingredients can be kneaded vigorously without worrying about temperature rise until the yeast is mixed in. Therefore, stable and good bread making is possible throughout summer and winter.

Furthermore, since the yeast container 65 is housed inside the lid 68, the yeast can be dropped and put in without opening the entire lid, which not only makes it easy to set the yeast, but also prevents you from forgetting to set the yeast. It can be easily set later.

Furthermore, the present invention provides a driving device that generates a driving force for the opening/closing plate for introducing yeast by removing the part directly above the baking chamber and forming it in a position separated from the yeast container by a partition wall, so that the driving device is directly connected to the steam. This prevents steam or harmful hot air from entering the drive device, preventing problems such as rust or poor insulation, and ensuring that yeast does not fall into the yeast container. Therefore, it is effective as a bread making machine that does not fail in bread making.
