Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic bread maker having a baking control means.

[0002]

2. Description of the Related Art A conventional automatic bread machine will be described below.

In FIG. 4, reference numeral 1 is a baking chamber, 2 is a heater, 3 is a removable baking pan, 4 is a motor, 5 is a belt for transmitting the power of the motor 4, and 6 is driven by the motor 4. Mixing blade, 10 is a baking type 3
Is a temperature detecting portion that comes into contact with the outer surface of the pan to detect the temperature of the bread baking mold 3 for process determination and temperature control, 8 is a lid, and 11 is a control device that controls all baking.

Regarding the automatic bread machine comprising the above-mentioned components, the mutual relationship and operation of the components will be described below. As shown in FIG. 5, the cooking process was divided into two processes, a high temperature process and a low temperature process, depending on the temperature of the baking pan 3.

That is, when the temperature of the bread dough is about 30 ° C. or higher, over-fermentation tends to occur, so it is necessary to shorten the kneading time and the fermentation time. The fermentation time is shortened according to the process, and when the temperature is less than 29 ° C, the fermentation process is performed according to the low temperature process and the fermentation time is longer than that of the high temperature process, so that the temperature is good regardless of the room temperature or the temperature of the dough. I tried to cook fresh bread.

In this case, since the temperature of the baking pan 3 is directly detected by the temperature detecting section 10 in order to detect the temperature accurately, the control temperature of each step of each process is the same.

[0007]

However, in the above-mentioned conventional structure, in order to detect the accurate temperature of the removable baking pan 3, the temperature detecting portion 10 has a spring property to ensure the baking pan 3. There is a problem in that a complicated structure is required such that the temperature detecting element is brought into contact with it or the temperature detecting element is insulated and then covered with a metal cap.

The present invention solves the above-mentioned problems of the prior art, and has a very simple structure in which a movable part such as a spring is eliminated and the temperature detecting element is simply insulated and fixed. An object of the present invention is to provide an automatic bread maker capable of baking as well as the case of detecting and controlling.

[0009]

In order to achieve this object, an automatic bread maker according to the present invention detects a temperature by a temperature detecting section which is fixed in a baking chamber and detects its temperature. Equipped with a control device that controls baking, the control device has a plurality of processes with different control temperatures according to the program of the microcomputer, and detects the temperature of the temperature detection unit at a certain point after the start of cooking to One of the above is selected.

[0010]

With this construction, the temperature detecting section is brought into contact with the outer surface of the bread baking mold, the temperature thereof is detected, and the baking control is performed in the same manner as the restriction of baking.

[0011]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

In FIG. 1 showing an embodiment of the present invention, the same parts as those of the conventional example are designated by the same reference numerals and the description thereof will be omitted. In FIG. 1, reference numeral 7 denotes a temperature detection unit that abuts the outer surface of the baking chamber 1 to detect the temperature of the bread baking mold 3 for process determination and temperature control, and 9 is a control device that controls all baking.

Regarding the automatic bread maker having the above-mentioned respective components, the relation and operation of the respective components will be described below.

As shown in FIG. 2, the cooking process is divided into a high temperature process, a medium temperature process, a low temperature process, and a low low temperature process, and the temperature detection unit 7 at the time of process determination after a fixed time after the start of cooking. According to the detected temperature, when the temperature is 28 ° C. or higher, the high temperature process, when the temperature is 20 ° C. to 28 ° C., the medium temperature process, when 12 ° C. to 20 ° C., the low temperature process or when the temperature is 12 ° C. or lower, the low temperature process Z
One of the processes is the selected configuration.

In the determination of the control temperature by the heater of each of these processes, the temperature difference between the temperature of the baking pan 3 and the baking chamber 1 with respect to the outside air temperature is almost constant, so that the temperature of the baking pan 3 is optimally controlled. As described above, the control temperature of the temperature detecting unit 7 detected on the surface of the baking chamber 1 is determined for each process in consideration of the temperature difference between the baking pan 3 and the baking chamber 1 for each process. At that time, by determining the room temperature and selecting one of the plurality of processes, almost the same control as in the case where the temperature detecting unit 7 is provided in contact with the bread baking mold 3 can be performed.

The firing process will be described with reference to FIG. 3 and (Table 1). As shown in FIG. 3, when the firing process is started, the heater 2 is continuously energized, and when the temperature of the temperature detection unit 7 reaches the off temperature θ1, the heater 2 is turned off and the temperature of the temperature detection unit 7 decreases. When the temperature drops to the ON temperature θ2, the heater 2 turns on again. By repeating this, when 45 minutes, which is the time of the firing step, has passed, the heater 2 is turned off and the firing step ends.

Here, as shown in (Table 1), the off temperature θ1 and the on temperature θ2 are set to different temperatures in four processes.

[0018]

[Table 1]

That is, in the high temperature process, the OFF temperature θ1 of the temperature detecting section 7 is 152 ° C. and the ON temperature θ2 is 1.
The temperature is 47 ° C. In the middle temperature process, the off temperature θ1 of the temperature detection unit 7 is 149 ° C. and the on temperature θ2 is 144 ° C. In the low temperature process, the off temperature θ1 of the temperature detection unit 7 is 146 ° C. and the on temperature θ is 141 ° C. During the low temperature process, the off temperature θ1 of the temperature detection unit 7 is 1
The ON temperature θ2 is 138 ° C. at 43 ° C.

As described above, when the room temperature is detected by the process determination and one of the four processes is selected, the optimum control temperature is set at the room temperature, so that whichever process is selected, the bread baking mold 3 can be selected. The temperatures are almost the same, and the baked state is the same in any process.

[0021]

As is apparent from the above description of the embodiments, the present invention has a very simple mounting structure for fixing the temperature detecting portion to the firing chamber, and detects the outside air temperature by the process judgment and determines the temperature depending on the temperature. The temperature of the bread baking mold can be controlled by selecting one of the processes and setting the control temperature in that process to the temperature at which the bread is optimally baked taking into consideration the temperature difference between the baking mold and the baking chamber. It is possible to realize an excellent automatic bread maker capable of baking satisfactorily as well as in the case of detecting and controlling.
