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 bread making on a timer like an electric rice cooker.

(Prior Art) In general, bread making at home uses a kneading machine, a fermenter, a push rod, an oven, etc., and is only successful when the difficult control of temperature and time is skillfully managed. In order to electrically automate this bread-making work, which requires skill, like a rice cooker, an electric bread-making machine for home use as shown in FIG. 3 has been proposed.

In other words, Figure 3 shows a conventional electric bread maker (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.
Driven by the motor 3 mentioned above, the helmet 9 and the pulley 1 are
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.

15 is a temperature detection unit that detects the temperature of the kneading container 8, and 16 is a control device that controls the motor 3, heater 4, water supply device 14, etc., and the control conditions are set from an input device (not shown). .

In the conventional bread making machine configured in this way, when bread ingredients except water are put into the kneading container 8 and the desired baking time and control conditions are entered 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, until it reaches a predetermined temperature or 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. Bread making is completed after a predetermined time after entering the baking process.

(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, if you set the baking time the night before, for example, to bake the next morning, and supply water to the ingredients, 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, when such a separate water supply device 14 is provided, the water temperature rises 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. The yeast is killed,
If bread making becomes impossible, or in extreme cases, the water dispenser 14 freezes, the water dispenser 1 is turned on to save it.
It was necessary to take measures such as creating a heat-insulating structure for 4 and adopting a cooling configuration in the summer.

In addition, if you start the kneading process with yeast added, the temperature of the dough will rise at the same time as fermentation starts, so if you do not adjust the kneading process time according to the temperature at the beginning of kneading the dough, The temperature of the bread dough may rise too high or become too low, and there is a risk that bread making will fail. 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 using a process 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.

Note that 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 the yeast container is detachable from the lid 68 for ease of setting the yeast and cleaning. The upper part is exposed on the upper surface of the lid body 68, and the opening and closing lid 6
2 is provided so that yeast can be easily set from outside the main body, and it is configured so that it can be easily removed and cleaned. The problem was the ease of opening and closing.

In view of the various drawbacks and problems in the conventional bread making machines described above, the present invention has been developed to enable electrical timer baking without baking failures, and in particular to improve the opening/closing part of the yeast container lid 62, thereby making it possible to set the yeast. The purpose of the present invention is to provide a bread making machine that can be easily cleaned and cleaned.

(Means for Solving the Problems) The present invention achieves the above-mentioned object by providing an electric bread maker in which the pivot portion of the yeast container lid is made into an oblique oblong cross section, and the yeast container lid 62 is opened and closed. This is achieved by changing the rotation center position of the opening/closing shaft.

(Function) By employing the above configuration, the present invention allows the center of rotation of the yeast container lid, and therefore the rotation axis, to be at the furthest position from the center of the yeast container, thereby reducing the gap between the lid and the yeast container lid. In addition, when opening the yeast container lid, the center of rotation rotates at the position closest to the center of the yeast container, so the yeast container lid rotates without contacting the lid. The lid of the yeast container can be opened wide, so that a bread making machine can be constructed in which yeast can be easily set and cleaned.

(Example) Hereinafter, the present invention will be explained in detail with reference to Examples.

FIG. 1 is a sectional view showing an electric bread maker according to an embodiment of the present invention, and FIG. 2 is a sectional view showing the main parts thereof.

In both of these figures, 30 is the main body case of the bread making machine (hereinafter simply referred to as the main body), 31 is the chassis,
A motor 32 is fixed to this, and a cooling fan 3 for the motor 32 itself is attached to one end of the shaft.
3, a small pulley 34 is fixed to the other end, and a fan guide 35 is fixed around the cooling fan 33 to improve cooling efficiency. Further, a large pulley 37 is pivotally supported on the chassis 31 via a bearing 36, and a connector 38 is provided at the opposite shaft end.
is fixed, and the small pulley 3 is connected via a belt 39.
4 and a large pulley 37 are rotatably coupled.

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 firing container 44 and a heat shield plate 45 covering the surroundings thereof are fixed. Further, a heater 48 is attached to the back surface of the firing container 44 by a stopper 47 via an insulator 46, and a container fixing spring 4
9, and an elastically supported temperature sensing section 50 are fixed. Further, 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, and a cylindrical guide 43 and container fixing spring 49 It is removably fitted and attached by the . 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 firing container 44 has an upper portion fixed to a fixing member 5.
Further, the upper frame 58 of the main body 30 is fixed to the fixing member 57 and also to the chassis 31.

Further, a driving force transmission plate 61 rotatably supported by a drive device 59 and a shaft 60 is provided inside the horizontal upper surface of the firing container 44, and a container lid 62 which can be opened and closed as well as a container lid 62 which can also be opened and closed. A yeast container 65 is formed on a lid body 68 having a lid cover 67 to which an inner lid 66 of the main body 30 is attached.

FIG. 2 is a sectional view of a portion of the yeast container 65 showing the details of the above-mentioned structure. As can be seen, the yeast container lid 62 has a shaft support 65-a provided so as to pass through the side of the yeast container 65. penetrate,
It is configured to open and close using a yeast container lid pin 72 fixed to the yeast container lid as a rotation axis. Further, the shaft support 65-a is formed as a through hole with an elongated cross section inclined upward as shown in FIG.

Returning to FIG. 1, by closing the lid 68, a firing chamber 69 is formed by the inner lid 66 and the firing container 44. 70 is a switch panel for inputting settings such as the baking time, and 71 is a control panel for determining and outputting control conditions for the motor 32, heater 48, etc. based on this input and the upper input of the temperature detection section 50. It is a device.

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 small pulley 34, the belt 39, and the large pulley 37, and the container connector 52 is driven by the twist, causing the inside of the kneading container 55 to be rotated. The kneading blades 53 are 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 laterally, 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,
The yeast is mixed and kneaded with other ingredients for a predetermined period of time. 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 be baked at the set time.

Furthermore, when setting yeast in the yeast container 65, the yeast container lid 62 is opened and closed, but as shown in FIG. Since the yeast container lid pin 72
will rotate around the X point (see the accompanying diagram in FIG. 2).

At this time, the C of the lid 68 and yeast container lid 62 is
If the center of rotation does not move from the X point when the yeast container lid 62 is opened, the yeast container lid 62 will generally only fit at an acute angle. It cannot be opened and therefore it is difficult to set the yeast. However, in the present invention, since the shaft support 65-a is formed into an elongated through-hole with an inclined cross section, the gap W is made smaller (FIG. 2) to prevent the yeast container lid 62 from colliding with the lid body 68. However, since the center of rotation moves from point X to point Y,
The yeast container lid 62 is separated from the lid body 68, so it can be opened wide, making it easy to put in yeast, and at the same time making cleaning easier.

The present invention has been described in detail with reference to one embodiment, but the present invention is particularly advantageous in that the shaft portion of the yeast container lid is made to have an oblique oblong gage-shaped cross section, and as the yeast container lid 62 is opened and closed, the center of the axis of rotation of the yeast container lid 62 is Its main feature is that it can change its position.

(Effects of the Invention) As is clear from the above detailed explanation, the present invention is capable of producing bread dough by dropping and adding yeast onto 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, etc., it can be made smaller, 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 the summer and winter.

Furthermore, since the yeast container 65 is housed inside the lid 68, it is possible to drop and put in the yeast without opening the entire lid.Therefore, not only is it easy to set the yeast, but also if you forget to set the yeast. However, you can easily set it later.

In addition, especially the yeast container lid 62 and the lid body 68
Even if the structure is designed to maintain the aesthetic appearance and prevent dirt from entering by reducing the gap between the lid 62 and the yeast container lid 62,
Since it does not come into contact with the lid 68, it can be opened wide, making it easy to set the yeast and to clean it.
