Specific embodiment
In order to make the object, technical scheme and advantages of the embodiment of the invention clearer, below in conjunction with the embodiment of the present invention
In attached drawing, technical scheme in the embodiment of the invention is clearly and completely described, it is clear that described embodiment is
A part of the embodiment of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, those of ordinary skill in the art
Every other embodiment obtained without creative efforts, shall fall within the protection scope of the present invention.
Fig. 1 is a kind of flow diagram of the clean method for water pump that the embodiment of the present invention one provides.In the present embodiment
The clean method of water pump, the water pump of application is interior to be equipped with driving motor, and water pump internal part can be driven to move, complete liquid
It draws and is discharged.As shown in Figure 1, the clean method of water pump provided in this embodiment can specifically include following steps:
S101, control driving motor rotate and water pump are made to generate vibration.
S102, the revolving speed for adjusting driving motor, change the vibration frequency of water pump, are taken off with causing the dirt of water pump to vibrate
It falls.
When carrying out cleaning operation, the driving motor in water pump can rotate water pump, and can drive the movement portion inside water pump
Part movement.Since the component inside the rotor and water pump of driving motor all has certain quality, so when driving motor rotates,
The generations such as drive water pump internal part or even water pump cover that can be different degrees of are vibrated accordingly.When the component and structure in water pump
Amplitude it is larger when, will drive dirt and deposit inside water pump and generate stronger vibration together.It is deposited on water pump in this way
Dirt on internal each component can fall off under the action of vibration from the inside of water pump, so that water pump cleaning action is played, and
It does not need to carry out dismantling operation to water pump.
It is common, it, can be in water when resonance to cause water pump internal part by adjusting the rotational frequency of driving motor
Carried out in the case where the pump liquid such as inner filling water, can also in water pump without working media in the case where carry out.Fig. 2 is this
The flow diagram of the clean method for another water pump that inventive embodiments one provide.As shown in Fig. 2, and being full of inside water pump
When liquid, optionally, in the revolving speed for adjusting driving motor, change the vibration frequency of water pump, to cause the dirt of water pump to vibrate
And after the step of falling off, the clean method of the water pump can with the following steps are included:
S103, the dirt to fall off is discharged by the liquid stream inside water pump.
In this way, water pump can constantly carry out drain operation, so water pump when being rotated due to the driving motor work in water pump
Inside will form one liquid flow, the dirt and deposit to fall off by vibration, can be discharged inside water pump with liquid stream, without
It can be deposited on inside water pump again.
Wherein, for clearing up the liquid of dirt, either clear water, is also possible to the liquid that cleaning solution etc. has cleaning function
Body can reinforce the removing for being conducive to dirt to the cleaning effect inside water pump in this way.
And when inside water pump without liquid such as water, the resonance that again may be by water pump makes internal dirt out of water pump
Portion falls off, and the dirt split away off can be discharged inside water pump in task under water pump by liquid stream, or utilizes work
Tool etc. is poured out from water pump.
Specifically, since the shell structure itself of component and water pump inside water pump has certain shape and quality,
So correspondingly, different components and structure can have corresponding intrinsic frequency, when extraneous vibration source with the intrinsic frequency or
When being vibrated with frequency similar in the intrinsic frequency, it will drive component and structure generate resonance.Fig. 3 is that the embodiment of the present invention one provides
The third water pump clean method flow diagram.As shown in figure 3, adjusting the revolving speed of driving motor, make the vibration of water pump
Frequency variation can specifically include with causing the dirt of water pump to vibrate the step of fall off:
S1021, the revolving speed for adjusting driving motor；
S1022, when the vibration frequency of water pump reaches predeterminated frequency range, cause the structure member of water pump to resonate, thus
The dirt of structure member is vibrated to fall off.
Wherein, the component inside predeterminated frequency range and water pump and the resonant frequency of shell structure match, when water pump exists
Under the rotation of driving motor, when vibration frequency reaches predeterminated frequency, the resonance of water pump structure component can be caused, amplitude greatly increases
By force, it falls off so as to promote the dirt of adhesion on structure member to vibrate.
Specifically, the type due to water pump is more, such as water pump can be diaphragm pump, centrifugal pump, mixed-flow pump, axial-flow pump,
Vortex pump, any one in turbine pump.For different pumps, the internal structure member with different structure and shape, example
Such as, it is generally the case that water pump can be diaphragm pump, at this point, the structure member of water pump includes diaphragm, shell and valve etc., and tie
The eigentone of structure component is located within the scope of predeterminated frequency.In this way, when water pump is being equivalent to the intrinsic of water pump structure component
When vibrating under the frequency of vibration frequency, the structure members such as diaphragm, shell or valve will generate altogether under the vibration of water pump drive
Vibration, amplitude greatly enhance, the dirt on structure member can be caused to fall off, play cleaning effect.
Since different pumps have the structure member of different structure and shape, meanwhile, each pump may also have it is multiple not
Same structure member, and different structure members, so it rotate etc. when moving, is tied because its shape and structure are all different
The quality of structure component and the variation of centroid position be not also identical, thus cause different structure component can have it is different intrinsic
Vibration frequency.And water pump has only reached the eigentone of specific structure component when generating vibration, it could be to the structure
Component carries out the operation of resonance cleaning dirt.Thus, if water pump reaches certain default vibration frequency range, and cause a certain
When the resonance of structure member, other structures component can not be generated corresponding due to the difference of shape and structure in the frequency range
Resonance, thus also can not just generate scavenging effect.

Modulation, abbreviation PWM) signal change driving motor operating voltage, to adjust the revolving speed of driving motor.
Wherein, pwm signal is usually provided by the controller of driving motor.Controller is by exporting PWM letter of different size
Number, the different voltage of amplitude can be formed, thus operating voltage of different sizes can be provided for driving motor.In different work
Under voltage driving, the revolving speed of driving motor can accordingly change, to generate the vibration of different frequency.
In the present embodiment, the clean method of water pump includes the following steps: that first controlling driving motor rotates and generate water pump
Vibration, then the revolving speed of driving motor is adjusted, change the vibration frequency of water pump, is fallen off with causing the dirt of water pump to vibrate.This
The dirt that sample is deposited on inside water pump on each component can fall off under effect of vibration from the inside of water pump, to play water pump
