Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a mochi making machine that steams glutinous rice in the same hopper and then makes it into mochi.

Conventional technology In general, this type of mochi pounding machine steams glutinous rice using steam guided from a steam tank in a hopper equipped with mochi pounding blades at the bottom, and the temperature rises when the water in the steam tank completes evaporation. was detected by a temperature controller installed in the steam tank, and the sheathed heater installed in the steam tank was turned off to complete the process. A buzzer electrically connected in parallel with the temperature regulator is configured to sound when the temperature regulator is opened to notify the completion of steaming and prompt the user to switch to the next step of pounding mochi. . Furthermore, there were also configurations in which a manual timer device was connected in series to the buzzer, the timer device was manually adjusted after the glutinous rice had been steamed, and the buzzer sounded after the set time had passed.

Problems that the invention aims to solve: However, in the former case, which connects a buzzer in parallel with the temperature controller,
It is necessary to operate a changeover switch to move to the process, and since there is no notification that the ``pounding'' process is complete, the user has to check how well the rice cake is cooked while pounding the rice cake, making it inconvenient to use. It was hot.
In addition, if a manual timer device is connected in series to the latter type of buzzer, it is necessary to set the time for the ``turning'' stroke of the timer device after the ``bug'' stroke ends, and the buzzer is activated at the end of the ``sticking'' stroke. Due to the noise, it is necessary to operate a manual changeover switch to stop the switch, which is a time-consuming problem.

The present invention takes into account the above-mentioned conventional problems and provides a rice cake pounding machine that has a simple structure, can notify the completion of rice cake cooking, and has improved operability.

Means for Solving the Problem In order to solve this problem, the present invention has a cueing switch that enables the timer motor to be energized by the operation of the temperature regulator of the steaming circuit, and the timer motor is provided with a cue switch that enables the timer motor to be energized during the "turning" process. a timer circuit that energizes the timer motor, and an alarm connected in series to a time switch that opens and closes as the timer motor rotates; It is configured to notify when the ``sticking'' stroke is completed by the rotation of the motor.

Effect With this configuration, when the temperature controller of the steaming circuit operates, when the "mushi" process is completed, the completion of the "mushi" process is detected by the alarm due to the operation of the temperature regulator, and the cue switch is activated. The timer motor is energized through the timer motor to automatically shift to the "on" stroke, and the time switch can be opened to stop the alarm. When a predetermined period of time has elapsed in the "turning" process, the time switch is closed again and the alarm notifies the completion of the "turning" process, further improving the usability.

Embodiments Hereinafter, embodiments of the present invention will be described with reference to FIGS. 1 to 4.

In the figure, 11 is a main body, and 12 is a ceiling frame that covers the upper opening of the main body 11, and is formed to cover a hopper 13 that serves both as a steamer and a rice cake making bowl. 14 is a lid of the hopper 13, and 15 is a blade installed in the center of the bottom of the hopper 13, which is removably connected to a rotating shaft 17 of a motor 16 installed in the lower part of the main body 11. Reference numeral 18 denotes a steam tank constituting a steam generation chamber, and a sheathed heater 19 is attached to the outer bottom of the steam tank, and a thermosensitive temperature regulator 20 is provided on the outer periphery of the steam tank. The temperature regulator 20 detects a temperature rise due to completion of evaporation of water in the steam tank 18 and turns off the power to the sheathed heater 19.

Next, the electric circuit includes a switch body 24 consisting of a steaming switch 21, a mochi-making switch 22, an automatic switch 23 that interlocks the steaming switch 23a and the mochi-making switch 23b, a double-throw cueing switch 25, and a timer switch 24. A timer 28 equipped with a switch 26 and controlled by a timer motor 27
It is equipped with a buzzer 29 which is an alarm to notify the completion of the "bug" process and the "stick" process.

These electrical connections are connected to the steaming switch 2.
1 and a steam switch 23a in parallel, from the common contact 20a of the temperature regulator 20 to the normal temperature closed contact 20.
a steaming circuit 30 connected in series to the sheathed heater 19 via b, a mochi pounding circuit 31 connected in series to the motor 16 from the normal temperature open contact 20c side of the temperature regulator 20 via the mochi making switch 23b; A dedicated switch 22 is connected directly to the motor 16 in series, and one contact 3 of the cue switch 25 is connected through a parallel body of the steaming switch 21 and the steaming switch 23a, and the other contact A timer circuit 33 in which the timer motor 27 is connected in series by connecting 5 to the normal temperature open contact 20c and the mochi-making switch 23b.
, the normal temperature open contact 20c and the mochi-making switch 23
The alarm circuit 34 is connected in series with the buzzer 29 via the time switch 26 in parallel with the motor. Note that 35 is an energization display circuit that indicates that the "mushi" and "tsuki" processes are in progress.

The operation of the mochi pounding machine configured as described above will be explained below.

First, put a predetermined amount of water into the steam tank 18,
Put sticky rice in the hopper 13 and turn on the automatic switch 23. Then, the steaming circuit 30 is closed and the sheathed heater 19 is energized, and after a predetermined time, steam is generated from the steam tank 18 and the glutinous rice is steamed in the hopper 13. When the automatic switch 23 is turned on and the "bug" process starts, the timer motor 27 starts rotating in the timer circuit 33 as shown in FIG. Switch to the other contact 5 and stop. Furthermore, when the sheathed heater 19 continues to be energized and the water in the steam tank 18 is completely evaporated, the temperature of the steam tank 18 rises rapidly, the temperature regulator 20 is activated, and the sheathed heater 19 is cut off. At the same time, the temperature controller 20
By switching from the normal temperature closed contact 20b to the normal temperature open contact 20c, the mochi pounding circuit 31 is closed, the motor 16 is energized, and mochi pounding is started. At the same time, the notification circuit 34 is energized and the buzzer 29 starts sounding to notify the completion of the "mushi" process. Furthermore, the third
As shown in the figure, in the timer circuit 33, the timer motor 27 is energized via the other contact 5 of the cueing switch 25, and it also starts rotating at the same time.First, about 20 seconds after the start of the "pick" process, the timer motor 27 is turned off.
6 opens between contacts 1 and 2, and the buzzer 29 stops sounding. While the buzzer 29 is ringing, the cue switch 25 returns to the contact 3 side and continues to be energized. Further, when the "turn on" process progresses and 10 minutes, which is the "turn on" time set in the timer 28 in advance, has elapsed, contacts 1 and 2 of the time switch 26 close, the notification circuit 34 is closed, and the buzzer 29 starts sounding. Notifies when the rice cake is done. This buzzer 2
9 informs the user that the rice cake is finished, the rice cake is attached from the hopper 13, the automatic switch 23 is turned off, the rotation of the motor 16 and the sound of the buzzer 29 are stopped, and the rice cake pounding is completed. Even if the buzzer 29 starts sounding, the timer motor 27 will not stop unless the automatic switch 23 is turned off. After about 20 seconds, the time switch 26 will open and the noise will stop, allowing you to continue making mochi if you like. In other words, it is not determined which of the contacts 5 and 3 of the cueing switch 25 is "closed" at the start of the "picking" stroke. Therefore, next, the other contact point 5 of the cue switch 25 before the start of the "bug" process.
The case where is "closed" will be explained.

First, even if the automatic switch 23 is turned on, the contact 5 side of the cue switch 25 is "closed", and as shown in FIG.
7 does not rotate. When the temperature regulator 20 operates and shifts to the "on" stroke, the motor 16 starts rotating and the buzzer 29 starts sounding. Here, if the stop position of the timer motor 27 at the start of the "mushi" stroke is switched to contact 5 of the cueing switch 25 and is set to 4 seconds,
The buzzer 29 notifies the completion of the "mushi" process, which is approximately 16
Seconds are done. Next, the “tsuki” process progresses and “tsuki”
When 9 minutes and 56 seconds have elapsed, the buzzer 29 will sound for 20 seconds to indicate the completion of the "turning" process, as described above. In other words, when the contact 5 of the cue switch 25 is "closed" at the start of the "bug" stroke, the "bug"
Completion notification time and "on" time are shown in Figure 310
By shifting the position of the second, the time will be shortened by up to 10 seconds.

In addition, in the "turning" process, the temperature controller 20 is set to an operating temperature that will never return, and the "turning"
The journey never stops.

Also, when the steaming switch 21 is turned on, when the steaming process is completed, the buzzer 29 sounds for about 20 seconds to notify the completion of steaming.
However, since the mochi pounding switch 23b is not turned on, there is no transition to the "pounding" stage after the completion of the "mushi" stage.

Further, the dedicated switch 22 for pounding mochi is designed to be used not only for pounding mochi but also for various uses such as bread dough, and the timer 28 does not operate.

As described above, according to this embodiment, the steaming circuit 30
The timer circuit 33 includes a cue switch 25 that enables the timer motor 27 to be energized by the operation of the temperature regulator 20, and a timer circuit 33 that energizes the timer motor 27 in the "on" stroke.
The buzzer 29 is connected in series to a time switch 26 that opens and closes according to the rotation of the timer motor. Since the notification is set, it is possible to automatically transition from the "mushi" process to the "tsuki" process, and also when the "mushi" process is completed and the "tsuki" process.
It is possible to notify the rice cake pounding time at the completion of the process, and its usability is improved. Moreover, the buzzer 29 which is this alarm is shared with the "bug" completion and can be realized with an inexpensive structure.

Furthermore, the timer motor 27 is constantly rotated during the "pounding" process according to the execution of the mochi pounding circuit 31, and the opening/closing of the time switch 26 controlled by the timer motor 27 is "mushi" or "pounding".
Since this was carried out without being limited to the notification when the timer 28 is completed, there will be no problem even if the timer 28 is stopped in the middle (before the completion of the "tsuki" or after the notification of the completion of the "tsuki", etc.), and the next "bug" will be notified. It is possible to notify the completion of each "tsuki".

In addition, from the “mushi” process in the above example, the “tsuki”
Although a double-throw temperature regulator is used as a means for switching between strokes, the temperature regulator has a one-circuit opening/closing configuration, and another means such as a double-throw relay may be used, and the operation and effect will be different. does not occur.

In addition, the switching time of the double-throw type cueing switch of the timer is shortened by shortening the "closing" time of contacts 4 and 5.
It goes without saying that the time setting may be changed as appropriate, such as by reducing the difference in completion notification time between "bug" and "tsuki".

Furthermore, annunciators may be provided to notify the completion of the "bug" and "tsuki" processes, respectively.

Effects of the invention As is clear from the above explanation, the present invention has a cue switch that enables the timer motor to be energized by the operation of the temperature controller in the steaming circuit.
It includes a timer circuit that energizes the timer motor during the stroke, and an alarm connected in series to a time switch that opens and closes according to the rotation of the timer motor. Since the timer motor is rotated to notify the user when the "burning" stroke is completed, when the "bug" stroke is completed and the temperature controller is activated, the alarm will notify the temperature controller and the timer motor will be energized. Therefore, it can automatically move to the "tsuki" stroke and notify you with an alarm when the "tsuki" stroke is completed, and the operation can be stopped at any point in each of the "mushi" and "tsuki" strokes, and the operation ends in that state. Even if I let you,
In the next "mushi" process, complete the cue and "mushi"
The notification of the completion of the "pounding" process becomes reliable, and mochi pounding can always be carried out without failure, which has a great practical effect.
