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 rolling 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, Fig. 3 is a sectional view showing a conventional electric bread maker (hereinafter simply referred to as a bread maker), in which 1 is a main body case, which has a chassis 2 inside, a motor 3, a heater 4, and a heat insulating structure around the outer periphery. A firing chamber 6 in which materials 5 are arranged is fixed. A kneading container 8 having kneading blades 7 is detachably attached to the firing chamber 6, and a belt 9. The kneading blade 7 is rotated at a reduced speed via the pulley 10°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;
16 is the motor 3, heater 4, or water supply device 14.
The control conditions are set using 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 depending on the temperature of the kneading container 8, and the degassing process by the rotation of the motor 3 is repeated to advance the fermentation, and after a predetermined period of time, the heater 4 is energized and the baking process begins. After a predetermined time, bread making is completed.

(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 time will be 1.
I can't make one loaf at all. Therefore, 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 has become. 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. The yeast will die, making it impossible to make bread, or in extreme cases, the water dispenser 14 may freeze. To remedy this, measures such as making the water dispenser 14 have an insulated structure or adopting a cooling configuration in the summer are taken. It was necessary.

In addition, if you start the kneading process with yeast added, the temperature of the dough will rise at the same time as fermentation begins, so unless you adjust the kneading process time according to the temperature at the beginning of kneading the dough, the temperature of the dough will increase. The temperature may rise too high or become too low, which may result in bread making failure. Conversely, if you control the kneading start time so that the dough temperature is at the optimum temperature, the fermentation time will change each time, which may result in over-fermentation or under-fermentation, resulting in bread-making failures. there were.

In order to prevent the above-mentioned drawbacks and failures, bread ingredients other than yeast are put in the kneading container 8, and the bread is baked at the desired time after a certain period of time has elapsed, that is, after it has been boiled for a certain period of time. It has been proposed that bread is made by adding yeast at the required time, post-kneading, fermentation and baking, but according to this method, water dispenser 1
Although it is possible to make stable bread without 4 or an insulation configuration, in reality, a reliable specific configuration of an automatic yeast injection device has not been solved. Although the method is to let the container 8 fall naturally from directly above the baking chamber 6, the yeast container is configured to be detachable from the lid 68 for ease of setting the yeast and cleaning. The structure is such that yeast can be easily set from the outside of the main body by providing an opening/closing lid 62 and being easily removed and cleaned. The problem was the gap with 68 and the ease of opening and closing.

The present invention solves the various drawbacks of the conventional bread making machines mentioned above,
In view of the problems, to provide a bread making machine which is capable of electrical timer baking without baking failures, and in particular improves the opening/closing part of the yeast container lid 62, making it easy to set the yeast and to make cleaning simple. With the goal.

(Means for Solving the Problems) The present invention has achieved the above-mentioned object in an electric bread maker, in which the shaft support of the yeast container lid is made into an inclined elongated cross section, and the opening/closing shaft is opened and closed according to the opening and closing of the yeast container lid 62. This is achieved by changing the rotation center position.

(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 farthest 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, and the yeast is removed. The container lid can be opened wide, and therefore a bread making machine can be constructed in which yeast can be easily set and cleaning is easy.

(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 a main body case of the bread making machine (hereinafter simply referred to as the main body), 31 is a chassis, to which a motor 32 is fixed, and at one end of the shaft is a cooling fan 33 for the motor 32 itself. However, there is a small pulley 3 on the other end.
4 is fixed, and a fan guide 35 is fixed around the cooling fan 33 to improve cooling efficiency.

Furthermore, a large pulley 37 is connected to 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 rotatably connected via a belt 39.

Further, a switch lever 40 is rotatably supported on the chassis 31 around a shaft 41, and a switch 42 is mounted so as to be positioned above one end of the switch lever 40, and a cylindrical guide 43 , firing container 44
A heat shield plate 45 covering the surrounding area is 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. In addition, there is a kneading container 55 which 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. It is removably fitted and fitted with the The kneading container 55 is mounted in pressure contact with the temperature detection section 50 when it is mounted.

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 to the fixing member 57 and also to the chassis 31.

Further, a drive device 5 is provided inside the horizontal upper surface of the firing container 44.
9 and a drive force transmission plate 61 rotatably supported by a shaft 60, a container lid 62 which can be opened and closed, and an opening and closing plate 63 which can also be opened and closed are fixed, and a rotating shaft 64 is attached to the yeast. The container 65 is formed into a lid body 68 having a lid cover 67 to which an inner lid 66 of the main body 36 is attached.

FIG. 2 is a sectional view of a portion of the yeast container 65 showing details of the above structure, and as seen in this figure, the yeast container lid 65
2 passes through a shaft support 65-a provided to penetrate the side of the yeast container 65, and is opened and closed 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 body 68, the inner lid 66
A firing chamber 69 is formed by the firing container 44 and the firing chamber 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 that input and the upper input of the temperature detection section 50. It is a device.

The electric bread making machine of the present invention configured as described above firstly includes a kneading container 55 equipped with a kneading blade 53 and containing bread making ingredients such as flour and water excluding yeast.

The bread is set in the baking container 44, the lid 68 is closed, a predetermined amount of yeast 1 is put into the yeast container 65, and in this state, the baking time of the bread is set using the switch panel 70.

Thereby, after a certain predetermined time has elapsed, the motor 32
rotates the connector 38 via the drive system of the small pulley 34, belt 39, and large pulley 37, thereby driving the container connector 52 and rotating the kneading blades 53 in the kneading container 55.
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, the transmission plate 61 is driven laterally, the rotating shaft 64 is operated, the opening/closing plate 63 is opened, the yeast in the yeast container 65 is dropped and thrown into the kneading container 55, and the yeast is mixed with other yeast. The ingredients are mixed and kneaded 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 secondary 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. Therefore, the yeast container lid pin 72 rotates about the X point (see the illustration in FIG. 2).

At this time, if the gap between the 0 part of the lid body 68 and the yeast container lid 62 is set to the minimum size (a gap that does not look unsightly), if the center of rotation does not move from the X point when the yeast container lid 62 is opened, the yeast will The container lid 62 can generally only be opened at an acute angle, making it difficult to set the yeast. However, in the present invention, the shaft support 65-a is formed into an elongated through hole with an inclined cross section, so 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, yeast container lid 6
2 is separated from the lid body 68, so it can be opened wide, yeast can be easily introduced, and at the same time, cleaning etc. can be done easily.

The present invention has been described in detail with reference to one embodiment, but the present invention is particularly advantageous in that the shaft support of the yeast container lid is made into an oblique elongated cross section, and the center position of the rotation axis of the yeast container lid 62 is changed as the yeast container lid 62 is opened and closed. This is a major feature.

(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 system 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, which not only makes it easy to set the yeast, but also makes it easy to use if you forget to set the yeast. However, it can be easily set later.

In addition, even if the gap between the yeast container lid 62 and the lid 68 is made small to maintain the aesthetic appearance and prevent the intrusion of dirt, etc., the yeast container lid 62 does not collide with the lid 68, so it can be opened wide. , thus making it easier to set the yeast and cleaning.
