Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fully-automatic bread making machine capable of making freshly baked bread at a desired time simply by charging a predetermined material.

Conventional technology When baking bread at home, devices such as a kneader, fermenter, rolling rod, and oven are generally used, but it is very difficult to control temperature and time, and it is delicious regardless of time. It took a great deal of skill to make freshly baked bread.

In order to solve this problem, a baking machine with a kneading function, a fermentation function and an oven function housed in a single product
59-6649) or a fully automatic bread machine that automatically bakes bread by setting a timer as shown in FIG.
-3028) is being considered. In the case of the former, a drive mechanism is provided in an oven with a heater, a kneading container is installed in the oven, and after kneading and fermenting the materials, the kneading container is taken out, degassing and shaping are performed, and the kneading container is put into the oven again. It is put into shape fermentation and baking. In the latter configuration, as shown in FIG. 3, a frame 2 is provided inside a main body case 1, and a motor 3 and a heating tank 6 equipped with a heater 4 and a heat insulating material 5 are fixed to the frame 2. A pan die 8 having a kneading blade 7 is installed in the heating tank 6, and the kneading blade 7 is decelerated by a belt 14 and a pulley 15. Further, the heating layer 6 has a top plate 9
And a lid 11 having a steam hole 10 is fitted to close the upper ends of the heating tank 6 and the pan die 8. 12 is a timer, temperature control,
This is a voltage adjustment circuit. 13 is a temperature sensor, and this temperature sensor 13 is fixed to the outer surface of the heating layer 6.

With the above configuration, when the ingredients are put into the bread mold 8 and the timer is set, the operation starts at a predetermined time, each process is automated by the timer and temperature adjustment, and the bread is baked at the predetermined time.

Problems to be Solved by the Invention In such a conventional configuration, the former (Japanese Patent Publication No. 59-6649) is used.
In the case of No.), kneading and fermentation are performed automatically by setting a timer, but after fermentation is completed, once out of the oven, degassing and shaping are performed manually, then put in the oven again, and shaping fermentation and baking are performed. Therefore, for example, when eating freshly baked bread, there is a problem that it is necessary to get up early in the morning to prepare and work. The latter (Japanese Patent Laid-Open No. 56-30
In the case of No. 28), the bread is automatically baked when the ingredients are charged and the timer is set, but when baking, steam is generated from the bread dough and the heating part is only on the side and bottom of the bread mold and the lid side. Since there is no heating part, baking of the side surface of the lid after baking the bread is poorer than that of the other surfaces, and most of the finished breads are not baked properly. Further, in the former case, since the heater is installed in the baking chamber, there is a problem in that if the radiant heat from the heater is picked up and baking is performed while the pan die is open, only one side is baked too quickly to obtain a good bread.

The present invention solves such a problem, and an object thereof is to always have good tasty bread automatically baked.

Means for Solving the Problems In order to solve this problem, the present invention is provided in a firing chamber case and a main body body having a firing chamber case which is provided with a connector driven by a motor and has an opening at the top. The lid body is equipped with a kneading blade that is driven and transmitted from a connector at the inner bottom portion and is detachably mounted in the baking chamber case, a lid that covers the upper end of the baking chamber case, and a heater. An inner lid is provided for the heater, and the heaters are attached to the inner lid on the outside of the firing chamber, which is composed of the firing chamber case and the lid, and the bottom of the firing chamber case, respectively.

Action With this configuration, even if the ambient temperature changes, the entire baking chamber becomes a heating surface and no baking failure occurs, and since there is no direct radiation from the heater, it is possible to always make fresh baked bread without uneven baking.

It is fixed to the pan type table 33 provided at the bottom of the
And pan-type pedestal that pivotally supports the pulley shaft 36 and lower connector 37
38 is detachably fitted. Further, an elastically supported temperature detecting portion 39 projects from a side surface inside the baking chamber case 30, and is in pressure contact with a side surface of the bread baking mold 32. Further, the upper surface of the baking chamber case 30 is closed by an openable / closable lid 40 and an inner lid 41 provided on the lower surface of the lid 40 to form a baking chamber 50. The upper heater 42 is in contact with the upper surface at the center of the inner lid 41.
The upper heater 42 is fixed to the lower surface of the lid 40. A water tank 43 is detachably attached to the lid 40, and a water injection solenoid 46 for opening and closing a water injection valve 44 of the water tank 43 to drop water from a water injection port 45 provided in the lid 40. And a steam removal solenoid 47 for opening and closing a steam removal hole (not shown) provided in the inner lid 41. 48 is a switch panel for input setting such as baking time. 49 is the input and temperature detector of the switch panel 48

Next, the operation of the present invention will be described with reference to FIG. Second
The figure shows the control state of each step of the dough temperature and time in the fully automatic bread machine of the present invention. Example A shows the state when the ambient temperature is high in the summer and Example B shows the state when the ambient temperature is low in the winter. Shows. Further, TA1 to TA5 indicate the dough temperature in each step of Example A, LA1 to LA5 indicate the time required in each step of Example A, and the same applies to Example B.

First, when trying to eat freshly baked bread at a certain predetermined time, put ingredients such as wheat flour in the bread baking mold 32, set it in the baking chamber case 30, close the lid 40, and set a predetermined amount in the water tank 43. Add water and attach to the lid 40. Then turn on the power and enter the baking time from the switch panel 48,
It will start automatically at a specified time.

First, as the kneading blade 31 is rotated by the rotation of the motor 23, the water injection solenoid 46 is operated at the same time, and the water is dropped from the water injection port 45 into the bread baking mold 32 and kneaded with the material such as wheat flour. At this time, as shown in Example A, when the ambient temperature and the temperature of the ingredients and water are high in the summer, the dough temperature TA1 at the beginning of kneading is high, and conversely, in the winter, the dough temperature TB1 is low.
Becomes When detecting this temperature, the temperature detection unit 39 provided so as to be pressed against the side wall of the bread baking mold 32 detects the temperature at any time during the kneading process, and based on this input information and the input information of the baking time. The controller 49 indicates that the subsequent kneading time (L
A1, LB1), fermentation temperature (TA2, TB2), fermentation time (LA2, LB2), etc. LA1-LA5, TA2-T
The conditions of A5, LB1 to LB5, TB2 to TB5 are set, and each device (heater, motor, etc.) is controlled to meet the conditions. For example, when TA1 is high in the summer, if the dough is kneaded for a long time, the temperature of the bread dough becomes too high, the elasticity of the bread dough is lost, and bread with bad blisters is baked. Therefore, the kneading time LA1 is set shorter than that of the low dough temperature LB1, and TA1, TB1
The kneading time LA1 and LB1 are changed so that good bread is baked. Similarly, fermentation time LA
Also in 2, LB2, when the temperature in summer is high, the activity of yeast is high, and if the time is long, it becomes overfermented and bread with bad blisters is baked as in the case of kneading. On the contrary, when the temperature is low such as in the winter season, the fermentation progresses slowly, so it is necessary to lengthen the fermentation time. Similarly to these, by setting the time and temperature of shaping fermentation, baking, etc. to an optimum value by detecting the bread dough temperature during kneading, good bread is always baked. When the baking is completed in each process set in this way, the steam removal solenoid 47 is operated to remove the steam, and the baked bread is immediately taken out and lowered to a temperature (TA5, TB5) at which it can be eaten for a certain period of time. (LA5, LB5) Keep warm. The baking time is controlled by the control device 49 so as to be set during this heat retention step. This is because if the bread is taken out at the time of baking, the baking chamber case 30 and the baking mold 32 are still in a high temperature state, there is a risk of burns, the baked bread is too hot to eat, and the inside of the bread is Because it is too soft and difficult to cut, it is baked at the time when it is kept at a suitable temperature without danger of being eaten deliciously. On the other hand, if the heat retention is continued, the bread is dried and becomes too hard, so the temperature is kept for a certain period of time. The most important part of the above process is to keep the dough temperature constant at the set temperature.
The lower heater 27 and the upper heater 42 are controlled based on the information obtained from (only one of the heaters can be used during the fermentation process) to heat the entire baking chamber 50 through the baking chamber case 30 and the inner lid 41. By this, the room temperature of the baking chamber 50 is raised and finally the temperature of the bread baking mold 32 is controlled. Further, as described in the above embodiment, by opening the upper end of the bread baking mold 32 in the baking chamber 50, steam generated from the bread dough does not stay inside the baking mold 32, so that the baking of the upper surface can be performed for a short time. Can be done efficiently.

EFFECTS OF THE INVENTION As described above, according to the present invention, the heater is provided outside the baking chamber of the baking chamber case and the inner lid that constitute the baking chamber, so that the baking chamber is surface-heated from the entire six surfaces, and the bread baking mold is provided. Also, by improving the uniform heating of the bread dough, it is possible to obtain the effect of automatically baking good bread with little baking unevenness.
