Abstract

PURPOSE:To eliminate incorrect external air temperature detection even at the time of continuous use of a bread baking machine by detecting the external air temperature by means of an external air temperature sensor at a specified time after the start of and within a dough making process and by controlling succeeding processes based on the detected temperature. CONSTITUTION:In a bread baking machine in which at least two processes of dough making and fermenting are performed, external air temperature is detected with an external air temperature sensor 10 and at the same time the dough making and fermenting processes are controlled with a control circuit 11. The control circuit 11 detects the external temperature with the external air temperature sensor 10 at a specified time after the start of and within the process and controls succeeding processes based on the detected temperature. As a result, erroneous detection of the external temperature can be avoided even at the time of continuous use of the bread making machine, making it possible to perform the control related to the processes of fermentation etc., properly at all times and to set different control values properly.

Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Application Field) The present invention relates to a bread making machine that performs at least two processes, a cross-breeding process and a fermentation process, in sequence.

(Prior Art) Conventionally, bread making machines knead flour, water, yeast, and other bread ingredients to produce bread dough, ferment the bread dough, and then bake it. In this bread making machine, the execution time of the cross-tracking process or the fermentation process is set to a value that corresponds to the execution time, and each process is time-controlled according to the set time.

(Problem to be solved by the invention) By the way, when fermenting bread dough, if the outside temperature, that is, the temperature of the room where the bread making machine is installed, is low, the fermentation time will be longer, and conversely, if the outside temperature is high, In some cases, the fermentation time can be shortened. However, in the conventional method described above, the fermentation process is controlled in a fixed pattern regardless of the outside temperature, so if the outside temperature is low, fermentation will be insufficient, and conversely, if the outside temperature is high, fermentation will be insufficient. There is a problem of excess.

As a countermeasure for this, the outside air temperature is detected by an outside air temperature sensor before the crosstalk starts, the process execution time is determined based on this detected temperature, and the fermentation process is controlled at this determined time, or the fermentation process is controlled until the fermentation process ends or the entire process is completed. It may be possible to control the subsequent steps, such as displaying the remaining time on the display, but in this case, the following inconvenience may occur.
There is a risk that it will break. In other words, when making bread again after making bread with a bread making machine, there is residual heat inside the bread making machine, so the outside air temperature sensor will be affected by the heat and the temperature will deviate from the actual outside temperature. If the fermentation process execution time is determined based on the false detection temperature, it may result in insufficient fermentation or the actual bread failure. There is an inconvenience that the time display on the display does not finish even though the product is baked. In particular, the execution time of the fermentation process has a great influence on the quality of the baked bread, so it is necessary to appropriately determine the execution time.

The present invention has been made in view of the above circumstances, and its purpose is to eliminate false detection of outside temperature even when a bread making machine is used continuously, and thereby properly control the process. We are able to provide bread making machines.

[Structure of the Invention] (Means for Solving the Problems) The present invention provides an apparatus in which at least two steps, a kneading step and a fermentation step, are performed in sequence, and an outside air temperature sensor provided to detect the temperature of the outside air. , a control device for controlling the kneading process and the fermentation process, and this control circuit detects the outside air temperature by the outside air temperature sensor at a predetermined time after the start of the kneading process and adjusts the temperature to the detected temperature. This feature is characterized in that it is configured to control the subsequent steps based on this.

Further, it is preferable that the detection timing of the outside air temperature is set at a predetermined time after the start of the kneading process and before the minimum required time of the cross-mixing process has elapsed.

(Function) According to the bread making machine of the above means, since the outside air temperature is detected at a predetermined time after the start of the kneading process during execution of the kneading process,
Unlike detecting the outside temperature before starting the crosstalk process,
When the bread making machine is used continuously, it is possible to secure residual heat reduction time and eliminate false detection of outside temperature.Furthermore, since the subsequent processes are controlled based on this detected temperature, the control can be carried out appropriately. can be done.

Moreover, if the detection timing of the outside air temperature is set to a predetermined time after the start of the kneading process and before the elapse of the shortest cross-mixing time of the cross-mixing process,
It is also possible to control the crosstalk process itself after the detection based on the detected temperature.

(Example) An embodiment of the present invention will be described below with reference to the drawings.

First, in Fig. 2 showing the overall configuration, 1 is the outer case 2.
The main body consists of an inner case 3, etc., 4 is the inner case 3
A container is removably arranged and fixed inside, 5 is an outer case 2
A motor 6 disposed at the inner bottom of the container 4 is a kneading blade removably disposed inside the container 4. This kneading blade 6 is connected to the motor 5
The motor 5 is connected to a rotating shaft 5a via a joint 7 and a drive shaft 7a, and is rotationally driven by the motor 5. 8 is a heater disposed at the inner bottom of the inner case 3;
9 is a container temperature sensor provided on the main body 1 to detect the temperature of the container 4, and 10 is an outside air temperature sensor provided on the inner bottom of the outer case 2 to detect the outside air temperature.

Figure 1 shows the electrical configuration, in which 1

2 is a motor drive circuit that receives a control signal from the control circuit 11 and de-energizes the motor 5; 13 is a heater drive circuit that receives a control signal from the control circuit 11 and de-energizes the heater 8;
14 is a start switch that gives a start signal to the control circuit 11 when turned on; 15 is a start switch for the control circuit 11;
A stroke indicator 16 receives a control signal from the control circuit 11 and displays the process being executed, and a time indicator 16 receives a control signal from the control circuit 11 and displays the remaining time until the end of the operation. The container temperature sensor 9 and the outside air temperature sensor 10 are configured to provide their respective detected temperatures to a control circuit 11.

The control circuit 11 has an operation control program, and according to the program, controls the drive of the motor 5 and the heater 8 as appropriate based on the detected temperatures and the like.
As shown in Figure (b), the crosstalk process, the fermentation process, and the baking process are sequentially controlled. Here, the contents of each of the above steps will be briefly described.

(A) The kneading process includes a primary mixing process at execution time T1 in which the motor 5 is driven (kneading tool 6 is rotated), a dough rest process at execution time Ill T2 in which the motor 5 is stopped, and a dough rest process in which the motor 5 is driven. and a secondary kneading process with an execution time T3.

(B) The fermentation process is the same temperature control as the primary fermentation process in which the heater 8 is turned on and off based on the temperature ty detected by the container temperature sensor 9 in order to control the bread dough to the fermentation control temperature ta. a primary degassing process with an execution time T in which the motor 5 is driven while performing the fermentation process, and a secondary fermentation process with an execution time T8 in which the same temperature control as in the -next fermentation process is performed,
- It consists of a secondary degassing process with an execution time TT in which the same control as the next degassing process is carried out, and a final fermentation process with an execution time T8 in which the control is similar to the -next and secondary fermentation processes.

(C) In the baking process, at execution time T9, the baking control section 2tb controls the heater 8 to be turned on and off in order to bake the bread dough.

Furthermore, the control circuit 11 detects an outside temperature sensor 10 at a predetermined time after the start of the mixing process, for example, at the end of the dough resting process (as will be clear from the description below, 10°5 minutes have passed from the start of the kneading process). Detects the outside temperature, determines control values for subsequent processes based on the detected temperature,
Based on the control value, subsequent controls such as stroke execution time control and display control of the time display 16 are performed. The target of the control value determined by the detected temperature tg of the outside air temperature is the execution time T3 of the secondary crosstalk process + the execution time T of the primary fermentation process of the fermentation process.
4 and the execution time TB of the secondary fermentation process, and the execution time T8 of the final fermentation process + the execution time T9 of the baking process. The detected temperature tg and the execution time T3, 'r, each control value are
,”6 + Ts.

The relationship with the determined value of T9 is shown in FIG. In addition, the execution time TI of the -th cross line process + the execution time T2 of the dough resting process
The execution time TS and T7 of each degassing process are the detection temperature tg
Constant value regardless of (TI-5°5 minutes, T2-5 minutes, T,
-8 seconds, T7-12 seconds).

Now, the operation of the above configuration will be described. Start switch 14
When turned on, the control circuit 11 starts the crosstalk process and displays the time required to complete the entire process (in this case, the maximum required time, that is, the required time when the outside temperature is the lowest) on the time display. 16, and the display time is decreased as time passes. An example of changes in the temperature ty detected by the container temperature sensor 9 is shown in FIG. 3(a). As described above, in this cross-crossing process, the primary cross-crossing process and dough resting process are executed, but when the dough resting process is completed, the control circuit 11 activates the outside air temperature sensor 10.
The detected temperature tg is read, and based on the detected temperature tg, the above-mentioned execution times ``3 + 'r, l 'r,
Determine l T's + T9. For example, the detected temperature tg
is in the range of "0°C or more and less than 10°C", Ts
T4 is set to 15 minutes, T4 is set to 33 minutes, T8 is set to 30 minutes, T8 is set to 75 minutes, and T9 is set to 50 minutes. Also, when the detected temperature tg is, for example, "33°C or higher", Ts is set to 10 minutes and T4 is set to 15 minutes.
for 0 minutes (-no next fermentation step) %T6 for 22 minutes, T
s and T are determined to be 56 minutes and 55 minutes, respectively.

After detecting the outside air temperature, the time until the end of the entire stroke is determined and the time is displayed on the time display 16. Note that this display time decreases with the passage of time thereafter. and,
The secondary kneading process of the cross-mixing process is executed for the determined execution time T3, then the fermentation process is started, and the determined execution time T
4, a second degassing step with a certain execution time T5 (8 seconds), and a determined execution time T6.
Secondary fermentation process with constant execution time T7 (12 seconds)
The secondary degassing process according to the above and the final fermentation process according to the determined execution time T8 are executed in order.

Finally, a baking process is executed for the determined execution time T9, thereby baking the bread.

By the way, when bread is manufactured again after bread is manufactured as described above, that is, when the bread making machine is used continuously, residual heat from the previous bread manufacturing is present inside the main body 1. Therefore, it is considered that the atmosphere surrounding the outside air temperature sensor 10 is also affected by the heat. However, in this second bread production, the residual heat decreases after the start of the kneading process, so the present embodiment detects the outside air temperature by the outside air temperature sensor 10 at a predetermined time after the start of the kneading process. In this case, the influence of the residual heat disappears, and as a result, the outside temperature can be detected properly. Therefore, each execution time T3, T4*'tel T8.

T9 is also determined appropriately, and as a result, subsequent processes (fermentation process, etc.) can be appropriately controlled,
Therefore, excessive fermentation can be avoided.

In particular, the outside air temperature is detected at a predetermined time after the start of the crosstalk process and before the minimum required time of the crosstalk process (in this embodiment, 10.5 minutes have elapsed from the start of the crosstalk process), that is,
The time required for the cross-traffic process when the execution time of the secondary cross-traffic process is 10 minutes (the required time is 20.5 minutes (5.5 minutes + 5 minutes +
10 minutes), it is possible to determine the control value based on the detected temperature tg after the detection of the crosstalk process itself.In other words, even though the outside air temperature is detected during the crosstalk process, this Control according to the outside air temperature is possible during the crosstalk process itself.

In addition, in the above embodiment, the baking process was performed in addition to the kneading process and the fermentation process, but it is sufficient if at least the mixing process and the fermentation process are performed in order.

In addition, the present invention is not limited to the above-mentioned embodiments, and can be implemented with various modifications without departing from the scope of the invention.

[Effects of the Invention] As is clear from the above description, the present invention can obtain the following effects.

According to the bread making machine of claim 1, even when the bread making machine is used continuously, false detection of outside air temperature can be eliminated, and various control values can be appropriately determined, and as a result, processes such as fermentation process etc. control can always be performed appropriately.

According to the bread making machine of the second aspect, the above-mentioned effects are achieved, and the kneading process itself can be controlled based on the outside temperature.
