Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic bread maker capable of making fresh bread simply by charging a predetermined material.

2. Description of the Related Art A conventional automatic bread maker has a structure as shown in the block diagram of FIG. 5, and when a user operates the starting means 1, the motor driving means 2 drives the motor 3 to knead the ingredients. Is driven. Based on the output of the temperature input means 4 for detecting the temperature of the baking pan, the heater driving means 5 energizes the heater 6 and controls the temperature of the baking pan to ferment the bread dough and bake it to make bread.
In the process of making the bread, if the power supply fails, the power failure detection means 7 detects the power failure, and after the power supply is restored, the power failure display means 8 notifies that the power failure has occurred.
When the power failure display is turned off, the canceling means 9 is operated to cancel the motor driving means 2 and the heater driving means 5, and at the same time the power failure displaying means 8 is turned off. When the canceling means 9 is not operated, the power failure display means 8 disappears when the bread is completed.

Problems to be Solved by the Invention With such a conventional configuration, even if there is a power failure on the way and the bread is poorly finished, it is not known that the power has been lost on the way when the bread is completed, and as a result, the user There was an inconvenience that it gave a feeling of distrust.

It is an object of the present invention to provide an automatic bread maker that solves such problems.

Means for Solving the Problems In order to solve the above problems, the automatic bread maker of the present invention is provided with a setting means for detecting that the bread baking mold is installed in the body and a power failure display means. When the subsequent user removes the bread baking mold, a cancel effective means is provided which can erase the display by the power failure display means by the output of the setting means.

Operation According to the above configuration, even if the bread is completed, the power failure display does not disappear, and even if the cancellation effective means is not operated, when the bread is completed and the baking bakery is taken, the display by the power failure display means is performed by the cancellation effective means. It can be erased.

Embodiment An embodiment of the present invention will be described below with reference to FIGS. 1 to 4.

FIG. 1 shows an automatic bread maker according to an embodiment of the present invention, in which a baking chamber 12 is provided in a main body 11 and a baking pan 13 is detachably attached to the baking chamber 12. A motor 14 is provided below the bread baking mold 13. The rotation of the motor 15 attached to the body 11 is transmitted to the shaft 19 by the small pulley 15, the belt 17 and the large pulley 18, and is also transmitted to the kneading blades 20. Further, the temperature of the bread baking mold 13 is detected by the temperature detecting means 21 that comes into contact with the bread baking mold 13.

FIG. 2 is a block diagram of the control device 22 shown in FIG. 1. When the user puts on the baking pan 13, the pan case switch located inside the baking chamber 12 (whether or not the baking pan 13 is installed) is shown. When the setting means 23 for detecting whether or not is turned on and the automatic bread making machine is started by the setting means 24, the motor 15 for kneading the ingredients is driven by the motor driving means 25. Then, the temperature of the bread baking mold 13 is detected by the temperature detecting means 21 and input to the temperature input means 26. Then, the heater driving means 27 energizes the heater 14 by the output of the temperature input means 26.

When the power supply fails, the power failure detection means 28 detects the power failure, and when the power supply is restored, the power failure display means 29 informs that there is a power failure.

Further, when the bread baking mold 13 is taken out and the bread case switch 23 is turned off, or when the switch which is the setting means 24 on the switch panel 30 in FIG. 1 is pressed, the cancel effective means 31 operates and the power failure display means 29 Turn off the display.

FIG. 3 shows the circuit diagram of FIG. Reference numeral 32 denotes a commercial power source, and the heater 14 is energized and controlled by a relay contact 33a and a relay coil 33b. The motor 15
Forward / reverse rotation control is performed by the forward rotation triac 34a and the reverse rotation triac 34b. Further, analog data from the temperature detecting means 21 including a thermistor is digitally converted by the A / D converter 35 and input to the microcomputer 36. Reference numeral 37 is a capacitor that backs up when the commercial power supply 32 fails. Reference numeral 38 is a resistor or capacitor for detecting a power failure of the commercial power supply 32. 24a starts bread making with the start switch. 24b is a cancel switch for stopping the bread making process and displaying
Turn off 39. 24c is a timer set switch, used when setting the timer for bread making. Reference numeral 23 is a pan case switch, and these switches are input to the microcomputer 36 as setting information. During the bread making process, nothing is input except for the cancel switch 24b and the pan case switch 23.

When a power failure occurs during the bread making process, the power failure detecting means 28 detects the power failure. Then, when the power is restored from the power failure, the character 40 "intermediate power failure" in the display device 39 lights up. This "intermediate power failure" display does not go out unless the input is prohibited, for example, during the bread making process, the pan case switch 23 is turned off or the cancel switch 24b is turned on.

FIG. 4 is a flowchart showing a part of the operation of the microcomputer 109.

In step 41, it is checked whether the start switch 24a is turned on, and if it is turned on, the process proceeds to the bread making step 42. If you don't turn it on, keep waiting until you turn it on. When a power failure occurs in the bread making process 42, the processing jumps to a power failure subroutine. In step 43, it is confirmed again that there is a power outage, and in step 44, it waits until power is resumed. Then, when the energization is restarted, the display 45 "intermediate power failure" is turned on and the process returns.
During the bread making process, it is checked in step 46 whether or not the cancel switch 24b is turned on, and if it is turned on, in step 47, the entire display of the display device 39 is turned off. On the other hand, if it is not turned on, then it is checked in step 48 whether or not the pan case switch 23 is turned off. If not turned off, the bread making process is continued. After turning it off, in step 49, check whether the "power failure display" is lit. If it is on, turn it off in step 50.

EFFECTS OF THE INVENTION As is clear from the description of the above embodiment, the automatic bread machine of the present invention does not turn off unless the power failure display is turned on or the bread baking mold is removed or the operation switch is pressed, so that the user feels distrustful. It has an excellent effect that the power failure display disappears even if the canceling switch dedicated to canceling the power failure display is not operated, so that there is no need to do it again and again.
