According to the above configuration, if the bread ingredients are not put into the bread case, even if the user tries to start the bread making process, the start means will not operate. This will eliminate the possibility of failure in bread making due to forgetting to add bread ingredients and proceeding with the bread making process.

EXAMPLE Hereinafter, an example of the present invention will be described based on FIGS. 1 to 4.

FIG. 1 shows the main body structure of an automatic bread maker according to an embodiment of the present invention. Reference numeral 11 indicates a main body, and a baking chamber 12 is provided in this main body 11.
A bread case 13 is removably installed inside. A heater 14 is provided in the baking chamber 12 below the bread case 13. In addition, the main body 1
The rotation of the motor 16 attached to the screwdriver 1 is transmitted to the shaft 19 by the small pulley 16, belt 17 and large pulley 18, and then to the kneading blade 2o. Reference numeral 21 denotes a temperature detecting means such as a thermistor, and this temperature detecting means 21 comes into contact with the bread case 13 to detect the temperature. Further, a part of the lower part of the bread case 13 is transparent, and there is a light emitter 22a and a light emitter 22a therein.
A light receiver 22b is set opposite to. And when there are no bread ingredients in the bread case 13,
Light from emitter 22a signals receiver 22b that no material is present. Furthermore, when bread ingredients are put into the bread case 13, the light from the light emitter 22a is blocked by the bread ingredients and does not reach the light receiver 22b. can be determined.

FIG. 2 shows a block diagram of a control unit in an automatic bread maker according to an embodiment of the present invention, and 23 is a bread case 1.
A detection means for detecting whether or not bread ingredients have been put into the container 3, that is, whether bread ingredients are present. Based on the output of this detection means 23, information on whether or not bread ingredients are present is displayed on the display means 24. That's what I do. When bread ingredients are not placed in the bread case 13, even if the user attempts to start the bread with the start means 26, the output of the detection means 23 prevents the start means 25 from starting. is output. It can be started when the bread ingredients are put in. First, the motor 16 is driven by the motor drive means 27 in order to knead the bread ingredients.

The heater control means 29 energizes the heater 14 based on the output of the temperature input means 28 that detects the temperature of the bread case 13, controls the temperature of the bread case 13, ferments the dough, and then bakes it. Create. Further, the remaining time of the bread making process and how far the process has progressed are displayed on the display means 24 along with information on the presence or absence of ingredients.

, FIG. 3 shows a circuit diagram of a control unit in an automatic bread maker according to an embodiment of the present invention, 30 is a commercial power source, and a heater 14 connected to this commercial power source 30 is connected to a relay contact 3.
1a, and energization is controlled by a relay coil 31b. The motor 15 kneads the bread ingredients by rotating forward or backward by a triac 32a for forward rotation and a triac 32b for reverse rotation. Temperature detection means 21 consisting of a thermistor.
The analog data from the resistor 33 is converted into digital data by the A/D converter 34 and sent to the microcomputer 3.
6 is input. 25 is a start means, and this start means 26 is constituted by a start switch that issues a start signal for the bread making process. The light emitter 22a is composed of an infrared light emitting diode, and when the infrared light emitting diode emits light and the phototransistor constituting the light receiver 22b receives the light, the light receiver 22b made of the phototransistor becomes on-site. The -r H1gJ level is input to the microcomputer 35 to detect that no bread ingredients have been put into the bread case 13. In addition, when no bread ingredients are put into the bread case 13, the microcomputer 3
5 stops the operation of the start means 26, which is a start switch, even if the start means 26, which is a start switch, is pressed, until the bread ingredients are put in. When bread ingredients are placed in the bread case 13, the light receiver 22b made of a phototransistor does not receive the light emitted from the light emitter 22a and is turned off, so that the rLOWJ level signal is input to the microcomputer 35. , detects that bread ingredients are put into the bread case 13.

24 indicates "no bread crumbs" when no bread ingredients are put into the bread case 13 based on the name of each bread making process, the remaining time of the bread making process, and information from the detection means 23.
36 is a display means that serves as a liquid crystal display to display that bread ingredients are not put into the bread case 13, and 36 is a start switch that displays when bread ingredients are not put into the bread case 13. This is a buzzer that gives a notification when the means 25 is pressed.

FIG. 4 is a flowchart showing the operation of the microcomputer of the control section in the automatic bread maker according to one embodiment of the present invention.

At step 100, the light emitter 22a is turned on. In step 101, it is checked whether the light receiver 22b has received light from the light emitter 22a. If the light receiver 26 is receiving light, no bread ingredients have been put into the bread case 13, so a message "No bread crumbs" is displayed in step 102. On the other hand, if the light receiver 22b does not receive light,
It is determined that the bread ingredients are in the bread case 13, and in step 103 it is checked whether the start means 25 consisting of a start switch has been input. If no input is made, the process returns to step 101. When the input is received, step 10 is performed again to determine whether the light receiver 22b is receiving light.
4, and if light is received, the buzzer 36 is sounded and the process returns to step 102, thereby stopping the operation of the start means 25 such as a start switch. On the other hand, if no light has been received, the process and remaining time are displayed in step 106, and the motor drive is started at step 10. If the temperature data from the temperature detection means 21 consisting of a thermistor is above a certain temperature in step 108, the relay 31 is driven to energize the heater 14 in step 109, while if the temperature data is below the certain temperature, Proceed directly to control the next process.

Effects of the Invention As is clear from the description of the above embodiments, the automatic bread making machine of the present invention is capable of starting the bread making process when no bread ingredients have been put into the bread case.
Since the prohibition means prohibits the operation of the start means from being performed, the bread making process may proceed without the user forgetting to add bread ingredients, resulting in a failure in bread making. It is something that can be eliminated.
