Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention relates to an accessory device that is attached to a hand mixer for domestic or commercial use for whipping cakes and performs the whipping process fully automatically.

(Conventional configuration and its problems) Figure 1 shows an external view of a conventional gutter mixer.

In the figure, reference numeral 1 denotes a speed changeover switch (hereinafter referred to as a switch), which can switch between four stages: (0), (1), (2), and (3). (0) is the switch OFF state,
In this state, the motor 3 built into the main body 2 remains stopped. (1) is low speed rotation of the motor 3, (2) is medium speed rotation, and (3) is high speed rotation.

The rotational force of the motor 3 is transmitted to the two beaters 4, which rotate in the direction of the arrow shown in the figure at a speed corresponding to the speed change of the switch 1.

To make sponno cake, follow the steps below.

FIG. 2 shows the timing chart i.

Put the sugar and rabbit in a bowl, and while slowly moving the mixer and bowl, mix at speed (1) for about 15 seconds, (2
) for about 15 seconds, whisk at speed (3) for about 4 minutes, and then stir at speed (1) for about 15 seconds. Next, sprinkle flour evenly over the whole mixture and immediately mix it for the first time.

After mixing the flour, bake in the preheated oven for about 40 minutes to complete the sponso cake.

Among these steps, the whipping operation requires the above-mentioned relationship between time and rotational speed in order to optimize this operation. "Switch" is O before time to

and continue whisking at high speed until a suitable state is reached (from time t2 to t3). At time t3, lift the beater, and when the material falls into a ribbon shape and the letters can be seen, switch 1 is returned to (1) to whisk at a low speed evenly, and at time t4 switch 1 is turned OFF. Make it.

FIG. 3 is an explanatory diagram showing changes in the position of the tower 1 of the switch. However, generally at time t. If the time distribution from t4''! is not appropriate, the whisking will be insufficient.
If the baked goods are too puffy or not yet risen,
Alternatively, the texture may become rough, making it impossible to bake a uniform cake.

(Object of the Invention) The purpose of the present invention is to eliminate the drawbacks of the conventional gutter mixer, and by simply attaching it to the gutter mixer, the rotation speed of the gutter mixer can be automatically adjusted to match the whipping condition. The objective is to provide an auxiliary device that can be controlled.

(Structure of the Invention) The accessory device for a no-no-no-no-no-mixer of the present invention includes: a switch for ON10FF control of no-no-no no mixer;
Time measuring means for measuring the time since the 0N10FF switch is turned on and providing information on what kind of control should be performed to the phase control means; and a DC voltage generator for providing a driving voltage for the time measuring means. By simply turning on the 0N10FF switch for the 1/U groove, the speed of the motor will be automatically controlled over time, allowing for proper lathering.

(Description of Embodiment) An embodiment of the present invention will be described based on FIGS. 4 to 8.

FIG. 5 is a block diagram of the circuit of this accessory device.

In the figure, 11 is a 0N10FF switch, 17 is a phase control means for controlling the current flowing to the motor 18, and 19 is 0N
10 Time measurement means 20 measures the time since the FF switch 11 is turned on and provides information on what kind of control should be performed to the phase control means 17; 20 is a time measurement means 19;
21 is an accessory device.

When the speed selector switch 22 is set to the high speed rotation tap (3) and the 0N10FF switch 11 is turned on,
A constant DC voltage is applied from the DC voltage generating means 20 to the time measuring means 19, and the time measuring means 19 starts measuring time. Until a predetermined time has elapsed,
The phase control means 17 uses this information to control the shimo motor 18 at a low speed (time t).

When the time has passed and the time t1 is reached, the time measuring means 19
gives information to the phase control means 17 to rotate at a medium speed,
The motor 18 begins to rotate at medium speed (time 1.).

At time t2, information is outputted to the phase control means 17 to perform high-speed control, and the motor 18 rotates at high speed. Next, at time t3, based on the low speed control information,
The motor rotates at low speed. At time t4, a motor stop command is issued and the motor 18 stops rotating.

If the times tl, t, .

FIG. 6 is a circuit diagram of the accessory device 210. In the same figure,
23 is a three-terminal regulator that provides a DC voltage, and 24 is an IC for measuring time, in which a microprocessor is used. 25 is a crystal oscillator that provides a clock for the microprocessor; 26, 27, 28; and 29 are transistors; 30a;

31b and 32b are relay contact parts, 33 is a diac,
34 is a trier 7 for controlling the phase of the motor 18.

The circuit diagram in Figure 6 is based on the professional diagram in Figure 5.
The only difference is that it is used as an input for the system 24.

FIG. 7 shows a flowchart of the microprocessor 24. In the figure, when the ON10FF switch 11 is turned on at time to, the microprocessor 24
inputs this information from the input terminal 35 and starts time measurement. The time is manually measured from the input terminal 36 based on the iron source frequency side, and is measured as 1 second, 2 seconds, and so on. At the same time, output terminal 37
outputs information from LE, turns on transistor 26, and outputs information from LE.
D12i is lit to indicate that the device is in operation.

Information is also output from the output terminal 38, and the transistor 27

is controlled at low speed (Z). At time t1, the output terminal 39
Information is also output from the transistor 28, which turns on the transistor 28. As a result, the coil 31a and the contact 31b are driven, and the phase control means 17 controls the motor 18 at a medium speed.

At time 2, information is also output from the output terminal 40, and the transistor 29 is turned on, causing the coil: 32a.

14 points 32b are driven, and the motor 18 reaches a speed f! ill
be shouted at. At time t3, there is no information from the output terminals 39 and 40, and only the transistor 27 is turned on. Therefore, the motor 18 (is again controlled at low speed 1iil). Then, at time L4, there is no information from the output terminal 38, so the phase control means 17 stops operating and the motor 18 stops rotating. At the same time, there is no information from the output terminal 37, the LED 12 goes out, and the i.tau.'-related device 21 notifies that 113!-stops 7'.

In this embodiment, the output of the microprocessor 24 is provided so as to sequentially close the contacts 30b, 31b, and 32b, but it is also possible to close only one of the contacts.

Also, a dedicated IC may be used for time measurement,
The diac 33 may be configured with trigger circuits with different thresholds and shoulders to control the phase.

FIG. 8 shows the waveform of the current flowing through the motor 18.

In the figure, time t. Previously, no current was flowing after t4, and from time to to t4, current was flowing only for the time indicated by diagonal lines.

From time to to t3, the area of the shaded area gradually increases, and the motor 18 changes from low speed rotation to
It can be seen that the rotation speed gradually increases. Similarly,
It can be seen that the area of the shaded portion becomes smaller between time t3 and time t4, which indicates that the motor 18 returns to low speed rotation again.
