JPH01164331A - Automatic bread maker - Google Patents

Abstract

PURPOSE: To enable a user to safely take out dough, to form dough within a prescribed time or to put An (bean jam), etc., into dough and to put it back to equipment, by constituting an automatic bread maker so as to stop the activity of equipment for a prescribed time when the user opens a lid in a midway of bread making, for instance, at the completion of kneading and fermenting of bread making. CONSTITUTION: A lid detecting means 23 outputs when a lid is closed to shut a contact. A microcomputer 26 is a one-chip computer constituted of CPU, ROM, RAM, I/O port, etc., which drives a relay 24 and TRIAC 25a and 25b and controls a heater 19 and a motor 13 to control bread making process of kneading, fermenting, baking, etc. However, since there is no output from the lid detecting means 23 when the lid is opened, the microcomputer 26 stops the heater 19 and the motor 19 for prescribed time, and then starts to actuate them again.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to an automatic bread maker that can produce freshly baked bread simply by adding predetermined ingredients.

2. Description of the Related Art As shown in FIG. 3, a conventional automatic bread making machine includes a baking chamber 2 having a heater 1, a bread baking mold 3 detachably attached to the baking chamber 2, and a bread baking mold 3.
A kneading blade 6 that is detachably installed at the inner bottom of the oven and driven by a motor 4, a lid 6 that opens and closes the upper opening of the baking chamber 2, and a control unit 7 that controls the heater 1 and the motor 4. When the user attaches the bread baking mold 3 with the kneading blades 5 set to the baking chamber 2, fills the bread baking mold 3 with bread ingredients such as flour, water, and yeast bacteria, and turns on the power to the device, The control unit 7 controls the motor 4 and heater 1 to perform kneading, fermentation, and baking according to a predetermined program, and automatically bakes bread.

Problems to be Solved by the Invention In the above-mentioned conventional configuration, when bread ingredients are put into the bread baking mold 3 and the device starts operating, the operation is stopped midway, the dough is taken out, and the dough is shaped into a dough. It was not possible to shape the dough or put ang or cream in the dough. Also, even if a switch is installed to temporarily stop the machine, if the user accidentally operates the switch,
The moment the lid 6 was opened and the user put his/her hand in, the kneading blades 5 would rotate, potentially injuring the user.

In view of these problems, the present invention takes out the dough during the kneading and fermentation process and reshapes the shape of the dough, or adds bread dough or cream to the dough and then re-processes the dough. An object of the present invention is to provide an automatic bread maker that allows the user to easily and safely return the bread to the device and continue cooking bread again.

Means for Solving the Problems In order to solve the above problems, the automatic bread maker of the present invention has a lid for opening and closing the upper opening of the baking chamber, and a lid detection means that comes out when the lid is open. and a control section that controls the heater and the motor and stops the operation of the device for a certain period of time when there is an output from the lid detection means.

According to the above configuration, when the user opens the lid after kneading and fermentation for bread cooking, the lid detection means detects this and the control unit stops the operation of the device for a certain period of time. For,
In the meantime, the user can safely take out the dough, change the shape of the dough, or put bread dough or cream into it, and return it to the device again, and after the certain period of time has elapsed, The operation of the equipment is restarted and bread making such as baking continues.

EXAMPLE Hereinafter, an example of the present invention will be described based on FIGS. 1 and 2.

FIG. 1 shows a sectional view of an automatic bread maker according to an embodiment of the present invention, in which a motor 13 is fixed to a chassis 12 provided in a main body 11, and this motor 1
A small pulley 15 is fixed to the shaft 14 of No. 3, and a large pulley 17 is connected to the small pulley 16 via a belt 16.
The percentage will be transferred to A heater 19 is fixed within the firing chamber 18. - Also, inside this baking chamber 18, there is a bread baking mold 21 provided with a removable kneading blade 20 at the inner bottom.
is detachably attached to the motor 13 and the kneading blade 2.
0 constitutes a kneading device. In addition, the firing chamber 18
A lid 22 is provided above the firing chamber 18 for opening and closing the upper opening of the firing chamber 18, and the firing chamber 18 is sealed by the lid 22. Reference numeral 23 denotes a lid detection means, and the lid detection means 23 is installed on the outer wall of the firing chamber 18, and its movable part 23a is biased by a spring so as to protrude upward from the upper surface of the firing chamber 18. When the is closed, the movable part 23a is pushed by the lower part of the lid 22, and the lid detection means 23 outputs an output.

FIG. 2 shows a circuit diagram of an automatic bread maker according to an embodiment of the present invention. Reference numeral 19 denotes a heater installed in the baking chamber 18, and its energization is controlled by a relay 24. 1
3 is a motor that rotates the kneading blade 20. Further, this motor 13 is a capacitor type motor, and this motor 13 rotates in the forward direction when one triac 25a is turned on, and rotates in the opposite direction when the other triac 25b is turned on. Reference numeral 23 denotes a lid detection means, and when the lid 22 is closed, the lid detection means 23 has a closed contact and outputs an output. 26 is a microcomputer, and this microcomputer 26 has a CPU and a ROM.

It is a so-called one-chip microcomputer consisting of RAM, input/output board, etc., and it drives the relay 24 and triacs 2E5a and 26b, and controls the heater 19 and motor 13 according to the program stored in the ROM in advance. Well, practice.

It controls bread making processes such as fermentation and baking.

However, if the lid 7 is opened in the middle of bread cooking, for example after kneading and fermentation, the lid detection means 23 will no longer output, so the microcomputer 26 will stop the heater 19 and motor 13 for a certain period of time. , and again causes the operation to continue.

Effects of the Invention As described above, the automatic bread maker of the present invention is capable of stopping operation for a certain period of time when the user opens the lid during bread cooking, for example, after kneading and fermentation. Since the structure is configured to allow the user to safely take out the bread dough and shape the bread dough within the specified time,
Alternatively, you can put the bread dough into the bread dough and return it to the equipment, and once the above-mentioned certain period of time has passed, the cooking operation such as baking will be continued again. It is convenient.
