Reference numeral 2 denotes a bread making means comprising a heating means for heating the bread container 1 and a kneading means for mixing the bread ingredients. 3 is a temperature detection means for detecting the temperature of the bread container 1. 4 is a yeast container containing yeast. 6
is a yeast charging means for charging the yeast from the yeast container 4 into the bread container 1. 6 is a start means for outputting a signal to start bread making. 7 inputs the signal from the start means 6, drives the kneading means of the bread making means 2 to knead the bread ingredients in the bread container 1, and then drives the yeast charging means 6 to mix the yeast in the yeast container 4. bread container 1
put it into. Next, input the signal from the temperature detection means 3,
It is a control means that controls the heating means of the bread making means 2 so as to keep the bread container 1 at an appropriate temperature during the fermentation and baking steps. This bread-making method involves adding yeast after kneading bread ingredients, and is called the medium noodle method.

Problems to be Solved by the Invention However, in such a configuration, when the yeast in the yeast container 4 is put into the bread container 1.

In some cases, not all of the yeast is added in one adding operation, and several yeast adding operations are required, and there is a problem in that the sound of this operation becomes loud and noisy. Mayu,
Even if the yeast charging means 6 is malfunctioning and yeast is not charged into the bread container 1, the first step continues and normal bread cannot be made, but the user must determine why normal bread cannot be made. However, there was a problem in that it was difficult to use, and it ended up being used again.

Therefore, the present invention detects whether or not there is yeast in the yeast container after the yeast addition operation, and as soon as the yeast runs out, the next step is started and the yeast addition operation is performed the minimum number of times to reduce noise. The purpose is to take advantage of the opportunity. Furthermore, it is an object of the present invention to provide a bread maker which notifies and displays a malfunction when yeast is not added even after the yeast injection operation has been performed n1 times so that the user can understand that the machine is malfunctioning, thereby preventing reuse. .

.

By turning off the motor 2C, the bread ingredients in the bread container 1 are kneaded without causing the motor 2C to rotate forward or backward. Next, proceed to step 62. In step 52, the count number n of yeast injection operations is set to an initial value of 0. Next, the process proceeds to step 63, and it is determined whether the counted number n of yeast injection operations is equal to or greater than a set number n1 (for example, equal to or greater than 3 times). If the yeast injection operation is less than n1 times (for example, less than 3 times), the process proceeds to the next step 64. In step 64, the counted number n of yeast injection operations is incremented by one. Next, proceed to step 66.

l, low level for input of microcomputer 7) V
is input. The microcomputer 7 determines the presence or absence of yeast based on the input voltage level, and if yeast is present in the yeast container 4, the process returns to step 63. When the yeast in the yeast container 4 has not been put into the bread container 1, the process proceeds to the first step 67. Therefore, the yeast addition operation can be performed at least once. The microcomputer 7 inputs the output of the temperature detection means 3 and controls the transistor 21 to turn on and off so that the temperature is optimal for fermentation.
Heater 2! Controls the energization rate to L.

I, - Makes the piezoelectric buzzer IQO sound to notify that there is a failure. Next, the process proceeds to step 60, where the output of the microcomputer 7, which is connected to and read by the resistor 9a, is set to a low level, causing the light emitting diode 9b to emit light, indicating a failure.
