【Embodiment】
The technical scheme of the embodiment of the present invention is explained and illustrated with reference to the accompanying drawing of the embodiment of the present invention, but under
Embodiment only the preferred embodiments of the present invention are stated, and it is not all.Based on the embodiment in embodiment, those skilled in the art
Other embodiment is obtained on the premise of creative work is not made, protection scope of the present invention is belonged to.
In the following description, occur the indicating position such as term " bottom ", " interior ", " outer ", " on ", " under " or
Person's position relationship is that, based on orientation shown in the drawings or position relationship, the description present invention merely for convenience is described with simplified, and
It is not instruction or implies that signified device or element there must be specific orientation, with specific azimuth configuration and operation, therefore
It is not considered as limiting the invention.
As shown in Figures 1 to 4, the present embodiment mesohigh cleaning machine includes body 1 and the storage tank 2 on body 1,
Control board 3, motor 4 and water pump 5 are provided with body 1, control board 3 is electrically connected with motor 4, the output shaft of motor 4 and
Water pump 5 is connected, and to drive the wheel rotation in water pump 5, water pump 5 is provided with water inlet 51 and delivery port 52, water inlet 51 and storage
Water tank 2 is connected by water inlet pipe 6, and delivery port 52 is communicated with giant by outlet pipe 7, when the driving water pump 5 of motor 4 works,
After water is pressurized by impeller in feeding giant.
Control board 3 in the present invention includes controller 31, drive module 32 and inspection leakage resistance 33, and drive module 32 connects
It is connected between controller 31 and motor 4, when controller 31 is to the transmission enabling signal of drive module 32, drive module 32 is according to startup
Signal control motor 4 opens work, and when controller 31 sends stop signal to drive module 32, drive module 32 is according to stopping
Signal control motor 4 is stopped, and one end of inspection leakage resistance 33 is connected with drive module 32, and other end ground connection is flowed through after motor 4
Electric current through drive module 32 flow direction inspection leakage resistance 33, flow through inspection leakage resistance 33 electric current it is equal with the electric current for flowing through motor 4, control
Device 31 processed is connected with inspection leakage resistance 33 close to one end of drive module 32, and the magnitude of voltage of the upper end of leakage resistance 33 is examined with real-time monitoring,
Due to examining the lower end ground connection of leakage resistance 33, therefore the lower terminal voltage value of inspection leakage resistance 33 is zero, examines the two ends pressure difference of leakage resistance 33
Namely examine the upper terminal voltage value of leakage resistance 33.
The detection in real time of controller 31 in the present embodiment examines the pressure difference at the two ends of leakage resistance 33 and calculates stream according to the pressure difference
Current value through motor 4.Because motor 4 has non-water flow required driving torsion to be excessively different when driving water pump in water pump
, in the case of having water in water pump 5, the driving torsion of motor 4 is big, and the electric current for now flowing through motor is also big, anhydrous in water pump 5
When, the driving torsion of motor 4 is small, and the electric current for flowing through motor is also small.Therefore the analysis of controller 31 judges to flow through the current value of motor
During for low current, controlled motor 4 is stopped, and efficiently solves water pump 5 and works long hours under anhydrous conditions the caused pump housing
Damage, improve security reliability, at the same it is cost-effective, reduce energy consumption；When the analysis of controller 31 judges current value for high current, control

Family is operated, and improves user experience degree.
It is preferred that, warning device is additionally provided with the body 1 in the present embodiment, warning device is connected with controller 31, controlled
The analysis of device 31 is when judging current value for low current, then control warning device is alarmed, anhydrous in user's water pump to remind, make user and
When moisturizing.Specifically, warning device can be warning lamp or buzzer, when warning device is warning lamp, then controller 31 can be controlled
Warning lamp flicker alarm processed；If warning device is buzzer, controller 31 can control buzzer rings to alarm.
The invention also discloses a kind of jetting machine water-free detection method, in the course of work of motor 4, controller 31 is real
When detection inspection leakage resistance 33 two ends pressure difference, and the current value I for flowing through motor 4 is calculated according to the pressure difference, by the electricity detected
The flow valuve I and current value I of setting0Compare, if it is determined that now flowing through the current value I ＜ I of motor0, then judge current value I to be low
Electric current, judges anhydrous in now water pump 5, controller 31 sends stop signal to drive module, and drive module 3 is according to stop signal
Controlled motor 4 is stopped, and control warning device alarm simultaneously；If it is determined that now flowing through current value I >=I of motor0, then
Current value I is judged for high current, judges there is water in now water pump 5, the controlled motor 4 of controller 31 works on.
For example, by setting electric current value I in the present embodiment0It is set to 10A, when controller 31 detects current value I less than 10A
When, then judge anhydrous in water pump 5, controller 31 is stopped by the controlled motor 4 of drive module 32, when controller 31 is detected
When current value I is more than or equal to 10A, the controlled motor 4 of controller 31 works on.Certainly, those skilled in the art can be according to reality
Situation is by setting electric current value I0It is arranged to other numerical value, it is within the scope of the present invention.
