Specific embodiment
In conjunction with a kind of shown in Figure 1, drainage arrangement provided in an embodiment of the present invention, comprising: drainage pipeline 1, drainpipe
Road 1 is connected to watering equipment 2, the draining for watering equipment 2；Vacuum pump 3, vacuum pump 3 is connected to drainage pipeline 1, for arranging
Waterpipe 1 vacuumizes.
Watering equipment of the invention can be the water conservancy project such as dish-washing machine, cleaning machine and make, the equipment drained.
The present invention adds vacuum pump in the discharge pipe line tail end of watering equipment, when draining pump can not thoroughly drain residual water
It waits, by entire discharge pipe line vacuumize process, the back-pressure principle generated using vacuum state and normal barometric pressure is in watering equipment
The residual water in portion empties, and leads to internal growth bacterium, smelly peculiar smell to solve the residual water of watering equipment.
In the present embodiment, drainage arrangement further includes solenoid valve block, and solenoid valve block is arranged on drainage pipeline 1, for closing
Or open drainage pipeline 1.Solenoid valve block includes the first solenoid valve 4；The close water of drainage pipeline 1 is arranged in first solenoid valve 4
One end of equipment 2, and/or, solenoid valve block includes second solenoid valve 5, and the separate use of drainage pipeline 1 is arranged in second solenoid valve 5
One end of wetting system 2.Two solenoid valves are separately positioned on the both ends of drainage pipeline 1, can close respectively, play closing drainpipe
Road 1；Two solenoid valves open simultaneously, and drainage pipeline 1 is unimpeded, and the inner cavity of watering equipment is connected to by drainage pipeline 1 with outside, use
Water in wetting system inner cavity can be flowed out with in-line arrangement waterpipe 1；The first solenoid valve 4 is only opened, drainage pipeline 1 is interior with watering equipment
Chamber is connected to, and the water in watering equipment can flow into drainage pipeline 1；Only open second solenoid valve 5, drainage pipeline 1 and watering equipment
Inner cavity is obstructed, and drainage pipeline 1 is connected to outside, and the water in drainage pipeline 1 can be discharged.
In the present embodiment, watering equipment 2 is equipped with draining pump 6, and drainage pipeline 1 is connected on draining pump 6.Draining pump 6 is
The water pump of 2 inner cavity of watering equipment can be pressed into drainage pipeline 1, to arrange by the common drainage equipment of the watering equipments such as dish-washing machine
Dry watering equipment inner cavity at stock water flow.But it to the fine and closely woven droplet of the surfaces such as 2 inner wall of watering equipment attachment, water stain can not arrange
Out, to cause the residual moisture in watering equipment.
The embodiment of the invention also provides a kind of water discharge methods, using above-mentioned drainage arrangement, solve residual in watering equipment
The problem of moisture can not empty completely.
In the present embodiment, water discharge method further include:
Step 1, control draining pump 6 start, and carry out pumping drainage.At this point, solenoid valve block is in initial opening state, row
Waterpipe 1 is dredged, and draining pump 6 starts, and the most moisture in watering equipment 2 is discharged, until again without at stock in watering equipment 2
Water flow discharge.
Step 2, control solenoid valve block movement, drainage pipeline 1 is closed.
When solenoid valve block includes the first solenoid valve 4, second solenoid valve 5, and drainage pipeline 1 is arranged in the first solenoid valve 4
Close to one end of watering equipment 2, when one end of separate watering equipment 2 of drainage pipeline 1 is arranged in second solenoid valve 5, control electricity
The step of closing of drainage pipeline 1, is included: to close the first solenoid valve 4, closes second solenoid valve 5 by the movement of magnet valve group.First electromagnetism
Valve 4, second solenoid valve 5 respectively close the both ends of drainage pipeline 1, at this time the closed space of 1 Inner Constitution of drainage pipeline.
Step 3 starts vacuum pump 3, drainage pipeline 1 is vacuumized.
It controls the vacuum pump 3 that is arranged on drainage pipeline 1 to start to work, drainage pipeline 1 is evacuated after negative pressure state,
Control vacuum pump 3 stops working.Air pressure is far below external pressure in drainage pipeline 1 at this time, also far below in watering equipment 2
Air pressure.
Step 4, control solenoid valve block movement, is connected to drainage pipeline 1 with watering equipment 2, negative pressure is arranged in drainage pipeline 1
Water in empty watering equipment 2.
When solenoid valve block includes the first solenoid valve 4, second solenoid valve 5, and drainage pipeline 1 is arranged in the first solenoid valve 4
Close to one end of watering equipment 2, when one end of separate watering equipment 2 of drainage pipeline 1 is arranged in second solenoid valve 5, control electricity
The movement of magnet valve group, the step of being connected to drainage pipeline 1 with watering equipment 2 include:
Step 4-1, the first solenoid valve 4 of control is opened, while second solenoid valve 5 being kept to close.When the first solenoid valve 4 is beaten
After opening, drainage pipeline 1 is connected to watering equipment 2, and the air pressure in drainage pipeline 1 is far below the air pressure in watering equipment 2, in negative pressure
Under effect, the pressure-air in watering equipment 2 can rapidly be poured in drainage pipeline 1, formation high-speed flow, in watering equipment 2
Remaining water stain can be swept along by air-flow into drainage pipeline 1.
Step 4-2, waiting time T, time T=1~2s, in residual water all suction drain pipelines 1 in watering equipment 2,
And collect in drainage pipeline 1.
Step 4-3, control second solenoid valve 5 are also opened, and the water flow in drainage pipeline 1 excludes.Due to drainage pipeline at this time
Air pressure in 1 is identical as external pressure, and the water flow in drainage pipeline 1 will not be by suck-back returning drainage pipeline 1.
It is the time difference opened using the first solenoid valve 4 and second solenoid valve 5, synchronous to utilize negative pressure of vacuum principle, it excludes residual
It stays water stain, understands peculiar smell.
A kind of dish-washing machine provided in an embodiment of the present invention, using drainage arrangement of the invention, relative to traditional dish-washing machine
Draining pump directly drains mode, increases the residual water that vacuum pumping pump can not drain draining pump completely in entire discharge pipe line and carries out
Emptying, leads to the smelly peculiar smell of dish washer interior to solve the residual water of dish-washing machine.
