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 a kneading machine, two fermenters, a push rod, an oven, etc., and by skillfully managing difficult temperature and time. 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.

That is, 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 firing chamber 6 having a heat insulating material 5 arranged around its outer periphery is fixed. A kneading container 8 having kneading blades 7 is detachably attached to the baking chamber 6, and is rotated at a reduced speed by the drive of the motor 3 via a belt 9 and pulleys 10.degree. In addition, the firing chamber 6
A lid body 13 having an inner lid 12 is formed to be openable and closable, and a water supply device 14 to the kneading container 8 is further provided.

15 is a temperature detection unit that detects the temperature of the kneading container 8;
Reference numeral 16 denotes a control device that controls the motor 3, heater 4, water supply device 14, etc., and its control conditions are set from an input device (not shown). When the bread ingredients except water are put into the oven and the desired baking time and control conditions are entered from the input device (not shown), at the predetermined time, the water dispenser 14 and the motor 3 are activated by a timer. The operation is started, and the kneading process proceeds while the temperature of the kneading container 8 is detected by the temperature detection section 15. When the temperature reaches a predetermined temperature or a predetermined time has elapsed, 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 add water to the ingredients the night before, the yeast fermentation will begin before the kneading process begins and the bread will not be made at all. become unable. 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. Moreover, when providing such a separate water supply device 14,
In the summer, the water temperature rises, so the water supply temperature during the kneading process is high.
As a result, the activity of the yeast increases too much, making it impossible to make satisfactory bread.In winter, the activity of the yeast decreases, and in some cases, the yeast dies, making it impossible to make bread, or in extreme cases, water supply The container 14 freezes, and in order to save it, it is necessary to take measures such as making the water supply device 14 a heat-insulating structure or 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 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 placed 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 rested 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.
However, stable bread making is possible without 4 or an insulation configuration.

However, in reality, a reliable and specific structure for an automatic yeast injection device has not been resolved. In addition, the yeast injection method involves letting it fall naturally from directly above the baking chamber 6 where the kneading container 8 is installed. The upper part of the baking chamber 6 must be kept airtight to some degree for temperature control and baking purposes, whereas the opening into which the yeast is dropped should be opened into the baking chamber 6 to ensure that the yeast will fall into it. Therefore, the inner lid 12 that seals the top surface of the baking chamber 6 is expected to be exposed to steam from the bread dough or pressed against it due to abnormal expansion of the bread dough, or yeast may remain attached to the inner lid 12 and prevent baking. In this case, there is a problem in that the opening and closing part formed on the inner lid for introducing the yeast becomes defective due to burning.

Various drawbacks of the above-mentioned conventional bread making machines of the present invention,
In view of the problems, it is an object of the present invention to provide a bread making machine which is capable of electrical timer baking without failures and which does not cause defects in the opening/closing part of the inner lid.

(Means for solving the problem of intertalk) The present invention achieves the above object by providing an opening/closing plate for opening and closing an opening for dropping in yeast in an electric bread making machine;
This is achieved by protecting or treating the surrounding members with a non-adhesive material or non-adhesive surface treatment.

(Function) By adopting the above-described configuration, the present invention prevents dirt from adhering to the opening/closing plate and its surroundings, or facilitates cleaning of the dirt, thereby exposing the opening/closing plate for dropping yeast into the baking chamber. This allows a yeast container to be formed, and therefore a bread making machine that can reliably charge yeast into a kneading container can be constructed.

(Example) The present invention will be explained in detail below using an example.

Further, a drive device 5 is provided inside the horizontal upper surface of the firing container 44.
A driving force transmission plate 61 is rotatably supported by a shaft 60 and a container lid 62, which can be opened and closed, and a rotary shaft 64 to which an opening and closing plate 63, which can also be opened and closed, is fixed. 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 30 is attached.

FIG. 2 is a cross-sectional view (a) and a top view (b) of the yeast container portion showing details of the above-mentioned configuration. As you can see, the yeast container 65 has an opening 65-a at the bottom.
A non-adhesive material 72 is sandwiched between the inner lid 66 and the lower surface of the inner lid 66, and is fixed so as to be exposed on the kneading container 55 side. A yeast input lower 2-a is formed with which the lower opening 65-a of the container 65 communicates, and an opening/closing plate 63 whose one surface is treated with a non-adhesive material 72 closes the input opening on the lower surface thereof. It is formed of.

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 baking time, and 71 is a control panel for determining and outputting control conditions for the motor 32, heater 48, etc. based on the input and information input from the temperature detection section 50. It is a device.

(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.

Furthermore, the lower opening 65-a of the yeast container 65
Nearby, at least the opening/closing plate 63 and its surroundings on the lower surface of the inner lid 66 are directly or
The bottom surface of 66 is treated with a non-adhesive material to prevent bread ingredients from adhering to it during bread making.
Alternatively, even if abnormally expanded bread dough collides with the opening/closing plate, or even if the dough is baked while still attached to the opening/closing plate, the adhering surface is made of a non-adhesive material or the surface is treated, so the dirt can be easily removed. There is no problem with the opening mechanism at the bottom of the yeast container, and yeast can be reliably introduced into the kneading container.
