Description

Mixer with stylized controlled mixing mode

The present invention relates to a mixer for agitating materials, and more particularly to a mixer having a stylized controlled agitation mode.

As shown in Fig. 15, the circuit control flow for the conventional mixer is mainly used for the mixing operation control of the food material, and the user controls the mechanism action of the mixer through the user interface 90, and the parameters including the stirring time and the stirring speed. It is set that the operation time and the operation speed of the motor 93 during the stirring are controlled by the timer 91 and the driver 92. However, the circuit control flow of this conventional mixer has the following problems:

1. As shown in Fig. 16, an encoder 94 is disposed between the driver 92 and the motor 93 to form a closed loop control between the driver 92 and the motor 93, mainly during the operation of the driver 92 to control the motor 93 while receiving the encoder. The speed indication of 94, at this time the driver 92 receives the feedback signal from the encoder 94, and causes the driver 94 to compensate the speed of the motor 93. Therefore, the encoder 94 is an essential component in the conventional circuit control flow. Although the driver 92 can obtain the feedback signal to compensate the motor 93 rotation speed, the encoder 94 itself is an additional component between the driver 92 and the motor 93. Failure of the device 94 causes the motor 93 to drive abnormally, and the arrangement of the encoder 94 also complicates the wiring between the driver 92 and the motor 93.

2. The circuit control flow of the conventional mixer can only set a combination of agitation time and agitation speed. Therefore, in the process of stirring the food material, the user not only memorizes the stirring material and the stirring step of the food material, the user The appropriate mixing time and stirring speed must be set according to different stirring steps. If the user forgets the stirring time and stirring speed of the relevant steps, or the user forgets the steps that have been carried out, the process will fail, so the human being is lost. The factor is greater than the control of the mixer.

When the stirring speed is set in the sub-category of each food material category in the embodiment, the stirring speed set by the preset six codes is commonly selected, that is, each sub-category can individually select the six codes in each stirring step. Either code is the selected agitation speed. In addition, when the stirring speed is set in the sub-category under each food category, the stirring speed can be set in each sub-category, except that the stirring speed can be set according to the preset six codes as the common option. That is, when the stirring speed of each step is set, the stirring speed of the above six codes is not shared, but each sub-category has a set of independent options including six codes, and each code also indicates a stirring speed, and the stirring speed can also utilize the setting. The pressing confirmation and the rotation selection of the portion 20 are changed, and as shown in Fig. 8, any code is selected as the stirring speed in each step, so that the selection of the stirring speed is more effective; further, in the stirring step of each sub-category If the stirring speed can be set independently, the setting page on page 9 can be omitted, which means that in the setting page on page 8, the code is directly replaced by the value of the stirring speed, and can be directly set in each step directly. Corresponding stirring speed.

If the formula content of the Polo bread is to be set, that is, the setting flow as shown in FIG. 10, when the mode/recipe key 24 is pressed for more than 2 seconds, the content of the recipe as shown in FIG. 11 is displayed on the display element 26. On the screen, the recipe for the blending of the Polo bread is displayed. If the content of each recipe is changed, the setting unit 20 is rotated to the specified recipe option, and after confirming by the setting unit 20, the rotatable setting unit 20 adjusts the parameters in the option, and then confirms the parameter by the setting unit 20, and the completion is completed. Then press the stop button 22 to end the setting.

After the above-mentioned stirring setting of the Polo bread is completed, the stirring in the automatic mode can be started. As shown in Fig. 12, the flow is in the automatic mode, that is, after the start key 21 is pressed, stirring is started according to the agitation step set as described above. During the stirring process, the pause button 23 can be pressed to suspend the stirring step, and then the start button 21 is pressed. The sequence is carried out to the unfinished step; in addition, during the stirring process, the stop button 22 can be pressed, at which time the stirring step will end, and if the start button 21 is pressed again, the stirring step starts from the beginning. In the present embodiment, if the stirring time is set to zero in a certain stirring step, and at this time, the stirring step is judged to be completed.

As shown in Fig. 13, in the manual mode process, when the vibrating key 25 is held down, the three-phase induction motor 15 is operated to rotate and revolve the agitating shaft 16, and when the agitating shaft 16 is moved to the appropriate position, it can be placed. The vibration key 25 is turned on to stop the three-phase induction motor 15; when the start key 21 is pressed, the three-phase induction motor 15 starts to operate according to the set stirring speed, and ends the three-phase induction motor when the pause key 23 or the stop key 22 is pressed. 15 operations. The stirring speed of the three-phase induction motor 15 can be set by the pressing and rotation of the setting unit 20, and as shown in Fig. 14, the display screen of the display element 26 in the manual mode includes the set stirring speed.
