First embodiment
Fig. 1 is refer to, the present embodiment provides a kind of washing machine 100, it includes water plug, aqueduct 130, pressure
Force snesor 140 and frequency converter 150.
Wherein water plug includes motor 110 and water pump 120.Motor 110 and water pump 120 are connected.
By the way that frequency converter 150 is connected with motor 110, motor 110 is connected with water pump 120, on aqueduct 130
Pressure sensor 140 is set, motor 110, water pump 120, aqueduct 130, pressure sensor 140, frequency converter 150 is formd
Closed-loop system, realizes low frequency, slow-speed of revolution operation, significantly reduces noise of the washing machine 100 in operation,
So that the wear extent of each transmission mechanism such as motor 110, water pump 120 is smaller, its service life is added, whole cleaning machine is improved
The using effect and service life of device 100.
Motor 110 is used to provide power for washing machine 100.Water pump 120 is connected in above-mentioned motor 110.
In this embodiment, it is preferred that, the specific drive connection mode of above-mentioned motor 110 and water pump 120 can be selected
Select the drive connection mode of V belt translation.
It should be understood that the drive connection mode of above-mentioned motor 110 and water pump 120 is not limited to the above-mentioned kind of drive.Take out
Water installations can select motor and the separately positioned device of water pump, can also select the device of motor and water pump integrated setting.
This structure is well-known to those skilled in the art, and here is omitted.
Further, motor phase failure protection is carried out to above-mentioned motor 110.So as to ensure motor 110 in voltage not
Shut down in the case of normal or phase shortage, protection motor 110 will not be damaged.
Frequency converter 150 is electrically connected to pressure sensor 140, and frequency converter 150 is electrically connected to above-mentioned motor 110.Frequency conversion
Device 150 can receive the hydraulic signal that pressure sensor 140 sends and according to the rotating speed of hydraulic signal controlled motor 110.
The power supply 160 that enters of washing machine 100 is connected to frequency converter 150.
By setting frequency converter 150, it is to avoid directly drive water pump 120 to be run at high speed with motor 110, operatively
The rotating speed of water pump 120 is reduced, energy consumption has been saved.
When the washing machine 100 that the present embodiment is provided, from 3,000 ten thousand motor when, 4 motors can be of use for 2.2
Ten million conventional clean machine.
Further, when the washing machine 100 that the present embodiment is provided, the rotating speed of the motor 110 of selection is highest 1400
When turning, the rotating speed of water pump 120 also only has 300 turns.
When the washing machine 100 that the present embodiment is provided it can be seen from examples detailed above, energy consumption is significantly reduced.
Further, because the rotating speed of motor 110 is reduced, whole washing machine 100 is also caused when operation, to make an uproar
Sound is greatly reduced, and improves the susceptibility used of washing machine 100, and using effect.
Further, using frequency converter 150, the rotating speed of motor 110 has been efficiently controlled so that whole washing machine
100 during operation, and pressure is constant, efficiently avoid start-stop cleaning device present in conventional clean machine, whole cleaning
The larger situation of machine pressure change, so as to preferably protection water pump 120.
Fig. 1 is continued referring to, further, water pump 120 selects big yield water pump.The structure of big yield water pump is relatively wide
There is buffer strip between pine, high-pressure water channel and lubrication storehouse, be also not in water pump lubrication even if water leakage situation occurs in high-pressure water channel side
Oil storehouse water inlet situation, so as to protect water pump linkage part not to be damaged.Conventional clean machine is efficiently solved, due to water
Small, pump body structure is compact, high-pressure water channel is isolated with water pump lubrication bunker by seal, once there is leak in high-pressure water channel seal
Situation, will directly seal in water pump lubrication bunker, cause oil storehouse water inlet, reduce water pump bent axle, the lubricant effect of chain bar part, from
And cause the phenomenons such as scuffing of cylinder bore, off-axis.
Big yield water pump is selected by above-mentioned water pump 120, so that each driver such as motor 110, water pump 120
The wear extent of structure is smaller, increases the service life of washing machine 100, improve the using effect of whole washing machine 100 with
And service life.
Further, the aqueduct 130 on washing machine 100, aqueduct 130 is communicated in water pump 120.Water inlet pipe
Road 132 is connected to water pump 120, so as to ensure the water that will enter by inlet channel 132, after water pump 120, can be defeated
See off, for follow-up washing and cleaning operation.
Pressure sensor 140 is arranged on above-mentioned aqueduct 130.Pressure sensor 140 is electrically connected to frequency converter
150。
Specifically, pressure sensor 140 is electrically connected to frequency converter 150 by sensor signal lines 141.Pressure sensor
140 can detect the hydraulic pressure in aqueducts 130 and export hydraulic signal.
It should be understood that in other embodiments preferably, above-mentioned pressure sensor 140 can also be selected by others
Mode is connected to frequency converter 150.Such as wireless signal, it is well-known to those skilled in the art that it, which is realized, is no longer gone to live in the household of one's in-laws on getting married herein
State.
Include at least one delivery port 131 on aqueduct 130, along water (flow) direction, each delivery port 131 may be contained within
After pressure sensor 140.
When washing machine 100 starts, pressure sensor 140 is 0, frequency converter 150 to the pressure signal of frequency converter 150
The high rotating speed of controlled motor 110, drives water pump 120 to run at high speed；When the pressure of supply water of water pump 120 reaches setting pressure, rotating speed is reduced,
When all delivery ports 131 are closed, pressure exceedes setting value.Pressure sensor 140 gives 150 1 high-voltage signals of frequency converter, frequency conversion
The controlled motor 110 of device 150 is stopped.
When all delivery ports 131 are opened, and hydraulic pressure is reduced to below setting pressure, controlled motor 110 works, and is set with reaching
Constant-pressure, delivery port more than 131, flow is bigger, and the rotating speed of motor 110 is higher, on the contrary then lower.
Further, washing machine 100 is in holding state, when the cleaning device for being arranged at delivery port 131 is opened, pressure
The pressure reduction of the aqueduct 130 of the side of sensor 140, now motor 110 can resume operation automatically state.
