Description

[Detailed description of the invention] (Field of industrial application) The present invention relates to an automatic bread maker for home use.

(Prior Art) The bread-making process can be roughly divided into three steps: stirring (kneading), fermentation, and baking. Among these, stirring and fermentation particularly require time and temperature control. For example, the temperature of bread dough needs to be kept constant at approximately 30℃, and if the temperature of the dough rises above 30℃ due to high ambient temperature, measures such as shortening the fermentation time to prevent over-fermentation are necessary. A control method is required. Therefore, conventional automatic bread making machines include a baking device, a container inside the baking device, a stirring device at the bottom of the container, a temperature sensing device for the container, and input information from a baking time input device to control the control conditions of each device. There is a type of apparatus which is composed of a variable control means and controls the time and dough temperature of each subsequent step by detecting the temperature of the container during the stirring step. (For example, Japanese Unexamined Patent Publication No. 62-5314) (Problems to be solved by the invention) According to the above configuration, it is structurally difficult to directly detect the temperature of the dough, so the temperature of the container is detected indirectly. Since the temperature of the dough is detected directly, there is a problem that a temperature difference occurs between the container and the dough depending on the ambient temperature, and depending on the conditions, it may not be possible to obtain preferable control conditions. Also, when baking bread continuously,
There were also problems such as control being performed under incorrect control conditions due to the influence of residual heat from the first cycle.

(Means for solving the problem) In order to solve the above problem, the present invention provides a room temperature detection means, and uses information from the room temperature detection means to correct the temperature difference between the container and the dough and adjust the control conditions of each process. It is provided with a control means for determining.

(Function) With the above configuration, when the room temperature is high, the container and the dough are at almost the same temperature,
When the room temperature is low, the temperature of the dough is lower than that of the container, so by detecting the room temperature, the temperature difference between the container and the dough is corrected and the control conditions for each subsequent process are optimized. , which always produces well-baked bread.

(Embodiment) An embodiment of the present invention will be described with reference to FIGS. 1, 2, and 3.

FIG. 1 shows the structure of an automatic bread maker.

In the figure, 1 is a main body, 2 is an opening/closing lid provided above the main body 1, and 3 is a container detachably attached to the main body 1. The stirring means includes an electric motor 4, a small pulley 5, a belt 6, and a large pulley 7 that transmit the power of the motor 4 at a reduced speed, and stirring blades 8 that rotate with the reduced power and stir the bread ingredients in the container 3. It is composed of The heating means is composed of a heater 9 provided at the bottom of the container 3, a fan heater 10 provided on the inner side of the refrigerator, a fan 11 that sends hot air into the refrigerator, and a fan motor 12 that drives the fan 11. The temperature detection means consists of a temperature sensor 13 that is in pressure contact with the bottom of the container 3 from below,
Information from this temperature sensor 13 is input to the control means 15. Further, the room temperature detection means is a room temperature sensor 14 provided at the rear of the main body 1, which is not easily affected by heat from the heating means.
The information from is input to the control means 15. The control means 15 controls the heater 9,
This is means for controlling the fan heater 10, electric motor 4, fan motor 12, etc.

The operation of this embodiment having the above configuration will be explained.

After putting bread ingredients into the container 3 and closing the lid 2, the bread making operation is started by pressing the start switch. The temperature of the fabric is detected by a temperature sensor 13 pressed into the bottom of the container 3, and the room temperature is detected by a room temperature sensor 14 installed in a part that is less affected by heaters and the like.

Now, when the room temperature sensor 14 detects a low temperature, the control means 15 controls the fermentation temperature to be higher than 30°C, and conversely, when the room temperature sensor 14 detects a high temperature, the control means 15 controls the fermentation temperature to be higher than 30°C. 30℃
control to a lower level. Further, the control means 15 changes the stirring/fermentation time, etc. according to the room temperature and dough temperature detected by the room temperature sensor 14 and the temperature sensor 13, so that bread is made under optimal control conditions.

Figures 2 and 3 show examples of control conditions for the automatic bread maker according to the present invention. Figure 2 is a control state diagram of process time by room temperature, and Figure 3 is a control state of set dough temperature by room temperature. It is a diagram. According to the figure, it can be seen that preheating is performed only at low temperatures, and dough temperature is set higher at low temperatures for kneading, kneading, kneading, primary fermentation, degassing, and shaping fermentation, as the time is longer at low temperatures.

(Effects of the invention) In this invention, a room temperature detection means is provided and a control means is provided to change the control conditions of each process according to the room temperature, so when the room temperature is low, the temperature of the dough may be lower than that of the container. Even if the temperature of the container is high, such as when baking bread continuously, the bread can be baked under the correct control conditions by detecting the room temperature, resulting in better quality bread.
