Description

 This invention relates to an automatic baking device, used mainly at home, and relates to the display of data during a bread making cycle.

 In recent years, home automatic baking devices have become popular in the market. Due to the need for automatic baking devices capable of making various types of bread, devices that can bake raisin bread are on sale.

 In the case of such baking devices, the dough is usually kneaded by the method shown in Fig.9.

During the first kneading, the motor drives the agitator blade for 7-10 minutes depending on the temperature detected by the temperature sensor. In a specific case, the dough is processed for 7 minutes during the first kneading, and then, when the test temperature rises to 35 ^o C, the threshold kneading temperature, this temperature will be detected by the temperature sensor, the first kneading process will be stopped. If the dough does not reach the threshold temperature within 10 minutes, the first kneading process will be stopped regardless of the temperature. When the mixing stops at some point between 7 and 10 minutes, a signal sounds to inform the user that it is time to add raisins. Kneading is suspended for 3 minutes in order to allow the user to add raisins.

 Then the second kneading process begins in order to mix the raisins, and lasts 2 minutes.

 However, as was the case with the prior art, it is not enough to simply notify that it is time to add raisins, as the user can skip the signal if he does not pay attention to the baking device during those seconds when the signal sounds. Typically, raisins can be placed in the device only during a limited time interval during the mixing process. Therefore, if the user misses the signal, then he misses the opportunity to put raisins in the device, making it impossible to make bread with raisins. Since the period of the mixing process depends on the ambient temperature, the time for adding raisins varies, which makes it difficult to accurately determine when the signal will sound.

To solve the above problems, an automatic baking device of the type described above, comprising:
a) a baking chamber with a heater,
b) a baking dish located in the baking chamber,
c) an agitator blade located inside the mold;
d) an engine for driving said mixer blade,
e) a controller for controlling said heater and said engine, and
g) display
equipped with means for calculating and displaying the time remaining before adding the ingredients, or the actual time for adding the ingredients, when manipulating a given switch or for a predetermined period when manipulating the switch.

 Preferably, said means provide for calculating and displaying the time remaining before adding the ingredients, or the actual time of adding the ingredients within a predetermined period after the start of the bread making cycle.

 Preferably, the device according to the invention further comprises a temperature sensor for detecting a test temperature in said device, wherein the indicated time remaining before adding the ingredients or the indicated actual time for adding the ingredients is set based on the output of said temperature sensor.

 The device according to the invention may further comprise a temperature sensor for detecting room temperature, wherein the device selects one of the plurality of internal bread making programs and displays the time remaining before adding the ingredients, or the actual time for adding the ingredients, calculated on the basis of which program was selected.

 The above functions of the device according to the invention allow users to successfully bake a wide variety of types of bread at home.

First preferred embodiment
A first preferred embodiment of the invention is described below with reference to FIG. 1-4. In FIG. 1 is a block diagram of an automatic baking device according to this embodiment.

 Let's start with the design of an automatic baking device. Inside the housing 1, there is a baking chamber 2 containing a heater 3 installed therein. A baking dish 4 is placed inside the baking chamber 2 in a removable manner and is heated by an electric heater 3. The motor 5 drives the stirrer blade 7 mounted on the bottom of the baking dish 4 by belt 6. During the bread making cycle, the temperature sensor 12, containing a thermistor 8, detects the temperature of the test and sends temperature information to the controller 9. If the controller 9 detects that the detected temperature is lower than constant temperature control bread manufacture, the controller 10 applies an electric heating current to the heater 3. When the duration measured by the controller 9, exceeds a predetermined period, the engine controller 11 supplies electric current to the motor 5 to turn on the kneading process or obmyatiya test. The controller 9 activates the display 14 and the signal 15, respectively, to indicate the time remaining until the appropriate moment of adding additional ingredients or until the completion of the bread production cycle, and to inform about the completion of the bread production cycle and time to add additional ingredients.

 The design of the input means 13 and the display 14 are described with reference to FIG. 2. In figure 2, all segments of the liquid crystal display 20 (hereinafter, LCD) are lit. The light emitting diode 21 (hereinafter, the LED) lights up during baking, flickers when the bread is kept warm after baking, and is turned off at another time. The button group 22 includes a menu switch, a timer switch, and a start / stop switch. The menu switch is used to set the cooking programs, the timer switch to set the cooking time and the start / stop switch to start and stop bread making cycles.

 In the case of an automatic baking device of the above construction, raisin bread is made in accordance with the process diagram of FIG. 3. The automatic baking device of this embodiment bakes bread with raisins in accordance with the bread making operations shown in FIG. 3.

 FIG. 4 shows an example of displaying bread making processes of an automatic device of this embodiment.

 "Stage 1" represents the display screen 14 when the start / stop button from the button group 22 is on after selecting the raisin bread. The display shows the state immediately after the start of the bread making cycle, and its LCD 20 shows the time remaining until the raisins are added. In this case, raisins must be added after 50 minutes (after the start of the bread making cycle). 30 seconds after "stage 1", the display screen switches to "stage 2", and now the LCD 20 shows that it will take another 4 hours before the cycle of making bread for raisin bread is completed.

 As described, the user can know for sure, immediately after the start of the bread making cycle, when it is necessary to add raisins, and can hastily begin preparing the ingredients after the start of the bread making process.

 In this embodiment, the display screen switches every 30 seconds from showing the time remaining until the raisins are added to showing the time remaining until the bread is made. However, this period is not limited to 30 seconds, it can be set, for example, to 5 seconds or 1 minute. Although the time remaining until the raisins are added is shown in this embodiment, the actual time of adding the raisins may be shown in the embodiment, with the same effect.

 In this embodiment, raisins are used as an additional ingredient. It is understood, however, that other ingredients such as nuts, including walnuts, may also be used.

Second preferred embodiment
The second preferred embodiment of the invention is described below. 5 shows input means 13 and a display screen.

 "Stage 3" provides a view of the display 14 30 minutes after the bread making cycle is started by turning on the start / stop switch from the group of buttons 22 after selecting the raisin bread. If the user presses the raisin adding time switch from the group of buttons 22 in order to find out the time remaining before adding the raisins, the display screen switches to “stage 4” for 10 seconds and informs the user that the raisins should be added after 20 minutes.

 In this embodiment, the “stage 4” display screen is shown for 10 seconds after pressing the raisin adding time switch, however, this period is not limited and can be set, for example, for 5 seconds or 1 minute.

 You can also set the display in such a way that the “stage 4” display screen appears only when you press the raisin input time switch from buttons 22. In this case, the user will see that the display shows the time remaining before adding the raisins, and he can confirm this time by pressing this switch. Therefore, the user will not confuse the time remaining until the raisins are added with the remaining time until the completion of the bread making cycle.

 As described, in accordance with this embodiment, the time remaining before adding the raisins can be found out at any time during the bread making cycle, and the user can prepare the raisins according to the remaining time. In this embodiment, the display screen switching button, raisin input time switch are added independently. However, the function of this switch can be assigned to other switches. For example, if this function is added to the timer switch, the user can figure out the remaining time by manipulating the timer switch during the bread making cycle. This easily and inexpensively provides the same advantage as the first preferred option, but without the addition of an additional switch.

 In this embodiment, the time remaining until the moment of adding raisins is shown, however, if the completion of the bread production is shown by the actual time, then the moment of adding the raisins can be respectively shown by the actual time.

Third Preferred Embodiment
The following describes a third preferred embodiment of the present invention. In FIG. 6 shows an example of a display screen of a third preferred embodiment.

 6 shows an input means 13 and a display 14 30 minutes after the bread making cycle is started by turning on the start / stop switch from the group of buttons 22 after selecting the raisin bread. LCD 20 simultaneously shows the time remaining until the completion of bread production, in capital letters like “3 hours 30 minutes” and “add raisins after 20 minutes”. This display screen allows the user to verify when to add raisins by simply looking at the display.

 Thus, the time remaining until the raisins are added can be viewed at any time during the making of bread, and the user can prepare the raisins accordingly.

 In this embodiment, the moment the raisins are added is shown as the remaining time, but in another embodiment, it may be shown as the actual time.

Fourth Preferred Embodiment
The fourth preferred embodiment of the invention is described below. FIG. 7 illustrates the kneading process included in the bread making cycle diagram shown in FIG. After the start of the bread making cycle, when the dummy in FIG. 3 is completed, the kneading process begins.

During the first kneading, the motor 5 drives the stirrer blade 7 to knead the dough for 7 minutes. As the temperature of the test rises, when the temperature sensor 12 determines that it has reached 35 ^o C, the threshold temperature to stop kneading, the kneading process will be stopped. On the other hand, if the test temperature does not reach 35 ^o C, then after 10 minutes the kneading process will still be stopped. In other words, the first kneading process lasts 7-10 minutes. In this embodiment, if kneading stops before 10 minutes, as in the case shown in Fig. 7, then the whole process stops before 10 minutes have elapsed, so that the time for adding raisins always comes after 10 minutes. After 10 minutes from the start of the kneading process, signal 15 warns the user that it is time to add raisins. The kneading stop then continues for another three minutes before the start of the 2 minute second kneading process, during which the raisins are mixed with the dough. Thus, the period of time between the start of making bread and the moment of adding raisins is fixed in one cycle of making bread.

In the prior art, as shown in FIG. 9, the kneading stop period for adding raisins was fixed at 3 minutes in order to reduce the stop as much as possible, regardless of the temperature of the dough. The reason that the stop period in the prior art is fixed was the opinion that if the kneading stop lasts for a long time at high temperature and for a short time, the dough becomes loose and high-quality bread cannot be obtained. However, the inventors of the present invention conducted thorough experiments to determine the optimum temperature to stop the kneading process, the second kneading period, and the magnitude of the added bread ingredients. As a result of these efforts, the authors of the present invention found that no noticeable effect on the quality of bread production is observed if the differences in the stopping period are 5 minutes or less at room temperature 25 ^{° C.} or higher, and 15 minutes or less at a temperature below 25 ^{° C.} .

 With the described automatic baking device according to the invention, even when the kneading period is not the same due to different temperatures, the period from the start of kneading to the moment of adding raisins can be fixed.

 In this embodiment, the first kneading process is set to 7-10 minutes and the second kneading process is 2 minutes, however, this period is not limited, and depending on the design of the device, in some cases, this period can be set to values other than those given above.

Fifth Preferred Embodiment
The fifth preferred embodiment of the present invention is described below. FIG. 8 is a diagram of a bread raisin production cycle. Automatic baking device according to this option contains a set (many) programs for making bread in the controller 9.

In accordance with this option, if the temperature detected by the sensor 12 immediately after the start of the bread making process is lower than 20 ^o C, then the bread making cycle starts in low temperature mode, at 20-28 ^o C in moderate temperature mode, and at 28 ^o C or higher in high temperature mode. The purpose of this function is to make bread without affecting the quality of the differences in room temperature by shortening the period of loosening (dough), when the temperature is high, in order to avoid over-loosening, and when the temperature is low, by increasing the period of loosening, in order to avoid insufficient loosening . The kneading process in this embodiment is the same as the kneading process in the fourth preferred embodiment, and the period until the raisins are added is fixed.

 In this embodiment, since the period of the bread making cycle is set at the beginning of the bread making cycle, the period before adding raisins can then be checked.

For example, if the detected temperature is 25 ^o C at the beginning of the bread production cycle, then the intermediate temperature mode is selected immediately after the start of the bread production cycle. Then, in accordance with the production of bread in the intermediate temperature mode, the bread ingredients are allowed to stand for 40 minutes before the kneading process. In other words, the time for adding raisins is 50 minutes after the start of the bread making cycle.

 As described, even in the case of a bread making cycle containing a plurality of processes, the period until the raisins are added can be set and displayed on the screen immediately after the start of the bread making process.

Industrial applicability
As described, the automatic baking device of the invention provides the following advantages.

 In accordance with the present invention, the time remaining until the addition of raisins or the actual time for adding raisins can be checked at any time during the bread making cycle, and the user can properly prepare the raisins and not be mistaken in adding them.

 The display according to the invention can show the time remaining until the raisins are added, or the actual time for adding raisins, therefore, the user can prepare the ingredients by checking the time when the raisins are to be added. Since the user can find out the time for adding additional ingredients by manipulating, at his request, the switch at any time during the bread making cycle, he will not miss the moment of adding raisins.

 The automatic device of the invention comprises a temperature sensor that detects the temperature of the dough in the bread pan. This sensor helps to record the period from the start of the bread production cycle to the moment of adding additional ingredients, and the user can prepare the ingredients at the right time, knowing exactly how much time is left. The automatic baking device according to the invention comprises a temperature sensor and a set (set) of bread making programs in the controller 9. Therefore, the device can accurately show the time until the ingredients are added immediately after the start of the bread making cycle. Thanks to the above functions, the invention allows the user to make high-quality bread at home with a high degree of success.

 In the above descriptions, raisin bread was used as an example. However, the automatic baking device according to the invention can be used with many other types of ingredients, and a suitable breadmaking program can be set in accordance with these ingredients.
