Embodiment
Fig. 1 is the circuit diagram of one embodiment of the invention blower module.Please refer to Fig. 1, blower module 100 comprises a control unit 120 and a fan 130, and wherein control unit 120 and fan 130 are electrically connected to each other.In addition, blower module 100 also comprises a sensor 140, and this sensor 140 can be current sensor or resistance sensing device, and the position that is provided with of sensor 140 determines according to demand.Generally speaking, build in the sensor 140 in the fan 130, need also can be arranged on other elements of blower module 100 but look it.
Fig. 2 is the flow chart of the starting fan method of Fig. 1 blower module, and Fig. 3 is the rotating speed and the time relation figure of fan.Please also refer to Fig. 1, Fig. 2 and Fig. 3, the starting fan method comprises the following steps: to provide said fans module 100 as step S110 at least.Afterwards,, provide a power supply 110, and make power supply 110 provide an electric power to give blower module 100, and power supply 110 is when beginning to power, just its electric power of supplying with is enough to drive fan 130 with full rotational speed as step S120.
Then as step S130, in a set time, control unit 120 judges whether fan 130 rotates, and wherein this set time can define voluntarily according to user's demand.As step S140, if fan 130 rotates, after through set time T, control unit 120 makes fan 130 rotate to set load speed afterwards, and wherein full rotating speed is greater than setting load speed.Perhaps as step S150, if fan 130 does not rotate, control unit 120 sends an alarm signal or a shutdown signal.To send shutdown signal is the example explanation, and afterwards as step S160, control unit 120 sends the electric power of shutdown signal with 110 fans that offered 130 of cutting off the electricity supply.
Specifically, judge whether the method whether fan 130 rotates rotates for detecting fan 130 by sensor 140, and pass a testing signal back control unit 120.According to the kind of sensor 140, the method for its sensing also is not quite similar.With the current sensor is example, build in the fan 130 in current sensor is common, relation V=IR according to voltage, electric current and resistance, wherein V is that voltage, I are electric current, and R is a resistance, if recorded current value, and current value tends towards stability in set time, be that fan 130 rotates, just fan 130 rotated to set load speed as step S140; Otherwise if detected current value not, or current value levels off to 0 in set time, is that fan 130 does not rotate, and as step S160 110 electric power that offer fan 130 of cutting off the electricity supply.
Further, power supply 110 provide the fixing voltages of fan 130 so that wind office 130 as expection with full rotational speed, if with offer fan 130 full the electric power of rotational speed fan 130 is rotated, the reason that can't rotate of fan 130 might be that dirt accumulation is on fan 130 herein, or the lubricant oil in the bearing is killed and frictional force is excessive etc., these reasons all can cause the load of circuit very big, in other words be the resistance value infinity, this moment, current value just can level off to zero, meaning is that current sensor can't detected current value, or measured current value is minimum.In the case, if power supply 110 continued powers press to fan 130, just cause the internal circuit temperature to raise easily and then burn out, blower module 100 just can wholely can't act on.So, detect fan 130 and do not rotate when current sensor connects in set time, after just that it is measured testing signal is passed control unit 120 back, cut off the electricity supply 110 power supply of control unit 120, as step S160, can therefore not damage to guarantee blower module 100.
In other embodiment, whether affiliated technical field personnel also can be to use OPTICAL SENSORS to measure fan 130 rotation.Is the example explanation with the OPTICAL SENSORS, OPTICAL SENSORS can be configured on other elements in the blower module 100, and the corresponding fan 130 of equipping position.When fan 130 is given in 110 power supplies as step S120 power supply, if fan 130 can rotate, OPTICAL SENSORS can be subjected to light off and on, so control unit 120 receives the testing signal that fan 130 is rotating, and then as step S140, control unit 120 control fans 130 rotate to set load speed behind set time T.If OPTICAL SENSORS is subjected to light constantly or is covered constantly and be not subjected to light in set time T, control unit 120 receives the testing signal that fan 130 does not rotate, and then as step S160, control unit 120 110 electric power that offer fan 130 of cutting off the electricity supply behind set time T.
As step S180, after control unit 120 sent the electric power of shutdown signal with 110 fans that offered 130 of cutting off the electricity supply, control unit 120 also can be closed the system that uses this blower module 100 afterwards.
Please continue with reference to figure 1 and Fig. 2, be the example explanation to send alarm signal again, as step S170, when fan 130 does not rotate, control unit 120 can be to send alarm signal to notify the user, allow the user close to use the system of this blower module, wherein alarm signal can be flashing light, caution sound or by modes such as panel display texts.Just as step S180, close the system that uses this blower module 100 afterwards.In step S180, closing of system can be by user's manual-lock, or is closed voluntarily after the electric power that detects fan 130 is cut off by control centre, is decided by user demand.
In sum, starting fan method of the present invention can provide the electric power that can make the full rotational speed of fan by power supply in a set time, and in this set time, detect fan and whether rotate,, then behind set time, make fan return back to load speed if fan has rotation; If fan does not rotate, then behind set time, cut off the electricity supply.Thus, can prevent to use the system of blower module not cause over-heat inside to cause the problem of component wear, and then prolong the working life of the system that uses this blower module because the initial stage fan does not have to rotate.
It should be noted that at last: above embodiment only in order to technological scheme of the present invention to be described, is not intended to limit; Although with reference to previous embodiment the present invention is had been described in detail, those of ordinary skill in the art is to be understood that: it still can be made amendment to the technological scheme that aforementioned each embodiment put down in writing, and perhaps part technical characteristics wherein is equal to replacement; And these modifications or replacement do not make the essence of appropriate technical solution break away from the spirit and scope of various embodiments of the present invention technological scheme.
