Therefore, the means to start the operation about 4 hours before the desired completion time is taken, but since yeast, which is indispensable for bread making, is greatly affected by the temperature of the water, they are separated from each other until the operation starts, or A means for controlling water to an appropriate temperature has been desired.

A conventional automatic bread maker has a structure as shown in FIG. 3, for example.

In the figure, 1 is a main body case, 2 is a chassis provided in the main body case 1, and this chassis 2 is provided with a motor 3, a heater 4, and a cooking chamber 6 equipped with a heat insulating material 5 on the outer periphery. A kneading container 8 having kneading blades 7 in the cooking chamber 6
Is detachably attached, and the kneading blade 7 is decelerated by the belt 9 and the pulleys 10 and 11. A lid 13 having an inner lid 12 is provided above the baking chamber 6 so as to be openable and closable. Further, in the main body case 1, a water supply device 14 for supplying water into the kneading container 8, a temperature detecting unit 15 for detecting the temperature of the kneading container 8, a control device for controlling the motor 3, the heater 4, the water supplying device 14, etc. 16 and an input device (not shown) for inputting control conditions of the control device 16.

Next, the operation of the bread maker configured as described above will be described.

When a material other than water is put into the kneading container 8 and a baking time or the like is input from an input device (not shown), the water supply device 14 and the motor 3 start operating after a predetermined time elapses, The kneading process proceeds while the temperature detecting unit 15 detects the temperature. When the temperature of the kneading vessel 8 reaches a predetermined temperature or when a predetermined time elapses, the motor 3 is stopped and the fermentation process is started. In this fermentation process, the heater 4 controls the temperature of the kneading vessel 8, and the motor 3 rotates to degas the material in the kneading vessel 8 and proceed. Next, when a predetermined time elapses, the heater 4
Is energized to move to the baking process, and the bread is baked at the desired time.

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention However, in such a conventional automatic bread maker, the water stored in the water supply device 14 becomes too hot in the summer to increase the activity of yeast by the time when the water is supplied to the kneading container 8. In winter, the temperature is low enough to kill yeast, and as a result, a means for controlling the temperature of the water in the water supply device 14 is required, and also a water supply device 14 consisting of a water tank and water supply means. However, the configuration of the above is not a simple one, so that the size of the entire body is increased.
