37, the lug boss 37 is located at 34 lower section of the water sucking mouth.The lug boss 37 by the diversion division 36 to flowing into the storage
The flow of water cavity 33 plays certain cushioning effect.Additionally, it is preferred that, in present embodiment, the lug boss 37 is set to institute
It states at the center immediately below water sucking mouth 34, and sets the lug boss 37 to the protrusion of circular cone or arc surface, then can make
The water uniform force in the storage chamber 33 is obtained, so as to uniformly flow into the water impeller 32.
The impeller blade material of the water impeller 32 is soft rubber.When there is relatively fine impurity in flow, compared to
The larger impeller blade of hardness, the impeller blade take the draining pump 3 out of during current scour conducive to impurity by flow.
Described in 3111 radial inflow of water inlet of the water through the draining pump water inlet pipe 311 flowed out from the washing water pump 2
Conduction part 35 is flowed into via the diversion division 36 in the storage chamber 37, when the draining pump 3 works, the storage chamber 33
Interior water is by upward suction force, so that water flows through the water sucking mouth 34 axially into the water impeller 32, flow
It is thrown away again to the draining water pump outlet pipe 312 by centrifugal force, and then the dish-washing machine washing system 100 is discharged.So design, it is real
Flow is showed axially into the water impeller 32, the purpose of the water impeller 32 has been radially flowed out, compared to radial direction stream
Enter water impeller, then the draining pump of radial direction outflow water impeller, the working efficiency of draining pump 3 of the present invention obviously carry
It is high.
Please refer to the first embodiment that Fig. 3 show dish-washing machine washing system 100 of the present invention.It is drained in the embodiment
It is connected in 180 ° of angles between pump water inlet pipe 311 and draining water pump outlet pipe 312.Please refer to Fig. 4,5 figures show and washed for the present invention
Second and third embodiment of bowl machine washing system 100.Draining pump water inlet pipe 311 is pumped out with draining in two kinds of embodiments
It is connected in two kinds of 90 ° of angles between water pipe 312.So design, can be according to reality in the actual production process of the dish-washing machine
The steric requirements of installation environment selects optimum a kind of angle design in three kinds of embodiments, to adapt to the dish-washing machine
Installation environment increases flexibility, provides convenience to installation.
In conclusion the dish-washing machine washing system 100 of the present invention is by by the water inlet of the draining pump water inlet pipe 311
The central axis of 3111 central axis and the water outlet 3121 of the draining water pump outlet pipe is disposed on the same plane, to drop
Low height of the dish-washing machine washing system 100 on 11 axial direction of the output shaft, reduces the size of dish-washing machine.It is logical
It crosses and the water sucking mouth 34 of the draining pump 3 is in axial direction arranged in the lower section of the water impeller 32 so that flow is in an axial direction
Direction radially flows out the water impeller 32 again after entering the water impeller 32, to improve the working efficiency of draining pump 3.
