[accompanying drawing explanation]
Fig. 1 is the structural representation of electric fan of the present invention;
Fig. 2 is the division schematic diagram in draw runner district in touch screen of the present invention.
[embodiment]
As shown in Figure 1, the present embodiment provides a kind of stepless speed regulating electric fan, comprise a main control chip, one touch control chip, one power driving circuit, one for showing the display modular of gear, one DC brushless motor, one touch screen and one is for giving the power supply adaptor of this electric fan power supply, this main control chip connects this touch control chip, this power driving circuit and this display modular, the output terminal of this power driving circuit is connected with this DC brushless motor, this touch control chip is connected with this touch screen, this touch screen is provided with one can slip control and the draw runner district of some control, one shift-up key zone and a downshift key zone.
Shown in Fig. 2, based on the electric fan of above-mentioned hardware configuration, the present embodiment also provides a kind of corresponding controlling method, it comprises the following steps: (1) is in this main control chip, by software programming, draw runner district is evenly divided into 7 grade districts, and these 7 grade districts distinguish corresponding 1 grade, 5 grades, 10 grades, 15 grades, 20 grades, 25 grades, 30 grades from left to right; (2) utilize this touch control chip to obtain the touch information of user in draw runner district, shift-up key zone and the downshift key zone of touch screen; (3) this touch control chip is given this main control chip by the touching position information of touch screen, this main control chip analysis also judges corresponding gear, by the mode of PWM, export gear control signal to power driving circuit, export gear display to this display modular simultaneously; (4) power driving circuit drives DC brushless motor to corresponding gear work, and this display modular shows actual-gear.
For example, current is the operation of 1 grade of wind speed, if be adjusted to 30 grades, can be realized fast by following two kinds of modes: 1, with hand in draw runner district from the most left slide to the rightest; 2, with hand, tap draw runner district low order end.
For example, if want, be switched to 17 grades, can in draw runner district, slide into or directly tap 15 grades or 20 grades, realize coarse adjustment, then tap shift-up key zone or downshift key zone and carry out every grade and be fine tuning to 17 grades.
This electric fan is also provided with a LED lamp bar being connected with this main control chip (on the body of electric fan, LED lamp bar is located at top, draw runner district), and its length equates with draw runner district, the demonstration of this main control chip control LED lamp bar.
The present embodiment provides the method for the two kinds of concrete LED of control lamp bars work:
The one: (101) carry out software programming in main control chip, design seven (identical from the quantity in the grade district in draw runner district) the different demonstration of LED lamp bar control programs, specifically, LED lamp bar is evenly divided into 7 from left to right and waits level length, seven different displaying schemes of LED lamp bar are seven different length that show specifically, be respectively first level length such as grade, the level lengths such as the first two, 7 are waited level length, corresponding 1-4 gear district from low to high respectively, 5-9 gear district, 10-14 gear district, 15-19 gear district, 20-24 gear district, 25-29 gear district, 30 gear districts, (102) utilize this touch control chip to obtain the touch information of user in draw runner district, shift-up key zone and the downshift key zone of touch screen, (103) this touch control chip is given this main control chip by the touching position information of touch screen, and this main control chip analysis also judges corresponding gear, then according to gear in that gear district, and export corresponding LED lamp bar control signal, (104) LED lamp bar carries out corresponding demonstration length according to LED lamp bar control signal and shows.While being 15 grades to 19 grades as wind speed, lamp bar is by bright half; When wind speed is 30 grades, whole lamp bar is entirely bright, as wind-speed gear indication, just as progress bar dynamically, directly perceived.
The 2nd: (201) carry out software programming in main control chip, design seven from the grade district different demonstration control programs of LED lamp bar one to one in draw runner district, specifically, LED lamp bar is evenly divided into 7 from left to right and waits level length, seven different displaying schemes of LED lamp bar are seven different length that show specifically, be respectively the level lengths such as first level length such as grade, the first two ..., the level lengths such as 7, respectively the grade district of the grade district of corresponding 1 gear, 5 gears ..., 30 gears grade district; (202) utilize this touch control chip to obtain the touch information of user in draw runner district, shift-up key zone and the downshift key zone of touch screen; (203) this touch control chip is given this main control chip by the touching position information of touch screen, this main control chip is analyzed the touching position information of touch screen and is judged the touch location in draw runner district, then according to the grade district output LED lamp bar control signal corresponding with the touch location in draw runner district; (204) LED lamp bar carries out the demonstration of corresponding demonstration length according to LED lamp bar control signal.If the touch position in draw runner district is when the grade district corresponding with 15 grades, lamp bar is by bright half; The touch position in draw runner district is when the grade district of 30 grades, and whole lamp bar is entirely bright, as the touch position indication in draw runner district; According to the touching information in draw runner district, control LED lamp bar and carry out the demonstration of corresponding length, there is following advantage: some naughty operator is in the process that electric fan is switched to 17 grades, likely to touch 10 grades in draw runner district, and then by shift-up key zone to 17 grade, at this moment, LED lamp bar still carries out the demonstration with 10 grades of corresponding length, by LED lamp bar, just can the person of knowing operator by mode the most efficiently, do not operate so, can educate it, with the life-span by mode operates to keep equipment the most efficiently.
The present invention is not limited to above-described embodiment, and for example, the grade Division in above-mentioned draw runner district is limited to 7 grades; Based on simple replacement above-described embodiment, that do not make creative work, should belong to the scope that the present invention discloses.
