As shown in Figure 1 to Figure 2, embodiment according to the present invention proposes a kind of drainage system 100, is used for dish-washing machine,
Including the first drain assembly 10 and the second drain assembly 20, the first drain assembly 10 includes cup 13, draining pump 12 and first row
The import of water pipe 11, draining pump 12 is connected to the bottom of cup 13, and one end of the first drainpipe 11 is connected to going out for draining pump 12
Mouthful；Second drain assembly 20, the second drain assembly 20 include water inlet pipe, the second drainpipe 22, the draining of third drainpipe the 21, the 4th
Pipe 25 and ejector pipe 23, ejector pipe 23 include water inlet end 231, water outlet 232 and injection end 233, and water inlet end 231 passes through water inlet pipe
Be connected to water system, the first pump chamber of draining pump 12 is connected to by the second drainpipe 22 with injection end 233, water outlet 232 and
One end of third drainpipe 21 is connected to, and the second pump chamber of the washing pump 40 of dish-washing machine passes through the 4th drainpipe 25 and injection end 233
Connection.
Drainage system 100 according to the present invention, when the drainage system 100 is applied to dish-washing machine, the first drain assembly 10
For the washing water collected in cup 13 to be emitted into the external world, the second drain assembly 20 will be for that will remain in the first pump chamber and the
Ponding discharge in two pump chambers.Specifically, when dish-washing machine, which washs, to be completed, the first drain assembly 10 is first opened, draining pump
12 start, and the washing water in cup 13 is discharged through draining pump 12 and third drainpipe 21, when washing water can not fill set solid water
When the import of pump 12, draining pump 12 is closed, then the second drain assembly 20 is opened, and clear water is passed through by water system through water inlet pipe to be drawn
The water inlet end 231 for penetrating pipe 23, in ejector pipe 23, clear water is flowed from water inlet end 231 to water outlet 232, and clear water leaves ejector pipe
23 water outlet 232 is discharged through third drainpipe 21, and the first pump chamber of injection end 233 and draining pump 12 passes through the second drainpipe
22 connections, when water is flowed through from water inlet end 231 to water outlet 232, the injection end 233 of ejector pipe 23 forms negative pressure, remains in row
Ponding in first pump chamber of water pump 12 is arranged through the second drainpipe 22, injection end 233, water outlet 232 and third drainpipe 21
Out, while injection end 233 is connected to the second pump chamber of washing pump 40 by the 4th drainpipe 25, when water is flowed through from water inlet end 231
When to water outlet 232, the injection end 233 of ejector pipe 23 forms negative pressure, remains in the ponding warp in the second pump chamber of washing pump 40
4th drainpipe 25, injection end 233, water outlet 232 and third drainpipe 21 are discharged.
Effectively realized by ejector pipe 23 in the first pump chamber to draining pump 12 and in the second pump chamber of washing pump 40 it is residual
The ponding stayed is discharged, and avoids remaining ponding and phenomena such as bacteria breed, corruption fouling occurs, effectively improves user's
Usage experience.
It is to be appreciated that ejector pipe 23 will be in the first pump chamber of draining pump 12 and washing pump by being passed through that clear water realizes
Remaining ponding is discharged in 40 the second pump chamber, whole process without using such as vacuum pump equal power device, so as to
The consumption of the energy is effectively reduced, thereby reduces the use cost of user.In addition, water system is dish-washing machine in the application
Water system, in other embodiments, water system are municipal water supply net, and the pressure of municipal water supply net can promote clear water stream
Through ejector pipe 23, to provide negative pressure for injection end 233, and then realizes and remaining ponding in the pump chamber of draining pump 12 is arranged
Out.
It should be pointed out that having main channel and injection channel in ejector pipe 23, wherein main channel is with narrow part
Variable-diameter structure, narrow part are connected to water inlet end 231, water outlet 232 and injection channel respectively, and main channel is located at water inlet end 231 1
The interior water inlet end without leave 231 of the part of side is gradually reduced to narrow part, and main channel is located at the internal diameter of the part of 232 side of water outlet
Be gradually increased from narrow part to water outlet 232, and main channel be located at 232 side of water outlet length be greater than main channel be located at into
The length of 231 side of water end (W.E.).When clear water enters in main channel through water inlet end 231, with the diameter of water inlet end 231 to narrow part
Be gradually reduced, the pressure of clear water is gradually increased, when clear water is after narrow part, with narrow part to water outlet 232 diameter by
Cumulative big, the pressure of clear water reduces suddenly, so that the position that injection channel is connected to narrow part forms negative pressure, so that injection
End 233 forms negative pressure, ponding under the action of negative pressure, in the first pump chamber of draining pump 12 and in the second pump chamber of washing pump 40
Enter injection end 233 through the second drainpipe 22 and the 4th drainpipe 25 respectively, then enters main channel, Jin Ersui through injection channel
Water flow is discharged through third drainpipe 21 jointly.
In addition, since position that draining pump 12 is connected to cup 13 is located at the lowest order of cup 13, when to draining pump 12
When remaining ponding is discharged in first pump chamber, remaining ponding gradually flows into the first pump chamber of draining pump 12 in cup 13
It is interior, to realize while the first pump chamber to draining pump 12 drains, can be realized to residual ponding in cup 13
Discharge, and then the discharge effect of residual ponding is improved, further improve the usage experience of user.
Furthermore water inlet pipe, the first drainpipe 11, the second drainpipe 22, third drainpipe 21 and the 4th drainpipe 25 are
Plastic part and be flexible structure, by using flexible structure, is convenient for pipeline layout, can effectively reduce the installation of drainage system 100
Required space can effectively meet the compact-sized requirement such as dish-washing machine.
It is further understood that, ejector pipe 23 is Venturi tube, and water inlet end 231 is the import of Venturi tube, injection end 233
For the aditus laryngis of Venturi tube, water outlet 232 is the outlet of Venturi tube.Drainage system 100 is applied to dish-washing machine, when the machine washing that washes the dishes
When washing completion, draining pump 12 starts, and the washing water in cup 13 is discharged through draining pump 12 and third drainpipe 21, works as washing water
When can not fill the import of set solid water pump 12, draining pump 12 is closed；After the closing of draining pump 12, water system is by clear water through intaking
Pipe is passed through the import of Venturi tube, and clear water is from the import of Venturi tube to output flow, after clear water leaves the outlet of Venturi tube
