Description
Technical field
The present invention relates to dish-washing machine blowdown apparatus, especially a kind of self cleaning exhaust pump.
Background technology
The dredge pump of existing dish-washing machine, its structure include motor, impeller and pump case, and the water inlet being arranged on pump case
And delivery port, impeller are arranged in pump case, it is connected with the rotating shaft of motor, water inlet connects with the pond of dish-washing machine.It is equipped this
During the dishwasher into operation of the dredge pump of structure, the swill discharge on bowl tool is not thorough, and the larger swill in part is detained
In machine, the time one is grown, residue obstruction water pipe and water jet, makes water-carrying capacity reduction, flows decrease in pipeline, causes to wash the dishes
Machine operating efficiency is reduced, and often manually to clean, and dismounting is not easy, and is wasted time and energy.
The content of the invention
The purpose of the present invention is in view of the shortcomings of the prior art, and to provide one kind and be not easy to block water pipe, operating efficiency
It is higher, without often dismounting cleaning, time saving and energy saving self cleaning exhaust pump.
The purpose of the present invention is realized by following technical schemes：
A kind of self cleaning exhaust pump, including motor, impeller and pump case, and the water inlet and delivery port being arranged on pump case, with
Unlike prior art：Breaker is provided between impeller and water inlet.
Described breaker is mainly made up of filter screen and broken blade, and the rotating shaft for crushing blade and motor connects, filter screen
It is arranged between broken blade and impeller.
The described broken blade rotated when described filter screen and work cooperates.
Described breaker is arranged in pump case, the inwall connection of described filter screen and pump case.
Or described breaker is arranged in a hollow cavity, the cavity one end connects with described water inlet,
The other end is connected by pipeline with the pump case before described impeller, and described filter screen is connected with the inwall of described cavity.
Importing gear is additionally provided with the inwall of the pump case or cavity before broken blade in described breaker
Plate, the importing baffle plate cooperate with the described broken blade rotated during work.
The quantity of described importing baffle plate is at least a piece of.
It is equipped with using the dredge pump and dish-washing machine of said structure, blade is crushed when being worked due to motor and is revolved simultaneously with impeller
Turn, the broken blade that the rotation being engaged first with filter screen is entered after water inlet in residue crushes, and then passes through strainer filtering
After discharge, so as to which the swill for avoiding larger is trapped in machine.In order to obtain more preferable crushing effect, importing gear is additionally provided with
Plate cooperates with the broken blade rotated during work, has effectively crushed residue, has further increased crushing efficiency and effect.
Therefore, the present invention have be not easy to block water pipe, operating efficiency it is higher, without often dismounting cleaning, time saving province
The advantages of power.
Brief description of the drawings
Fig. 1 is an embodiment of the present invention structural representation；
Fig. 2 is Fig. 1 A-A line of vision schematic diagrames；
Fig. 3 is another example structure schematic diagram of the present invention.
In figure, the filter screen 4. of 1. motor, 2. impeller 3. crushes the water inlet 6. of blade 5. and imports the delivery port 8. of baffle plate 7.
The pipeline of 9. hollow cavity of pump case 10..
Embodiment
Make further non-limiting explanation to present invention with reference to the accompanying drawings and examples.
Embodiment 1：
The Fig. 2 of reference picture 1, self cleaning exhaust pump of the present invention includes motor 1, impeller 2 and pump case 8, and is arranged on entering on pump case 8
The mouth of a river 5 and delivery port 7, breaker is provided between impeller 2 and water inlet 5.
Breaker is mainly made up of filter screen 3 and broken blade 4, and broken blade 4 is connected with the rotating shaft of motor 1, and filter screen 3 is set
Put between broken blade 4 and impeller 2.
Filter screen 3 cooperates with the broken blade 4 rotated during work.
Breaker is arranged in pump case 8, and filter screen 3 is connected with the inwall of pump case 8.
The pore size of filter screen can select different sizes according to being actually needed, and the filter screen in 1.5mm apertures is used in this example,
The aperture size of generally optional filter screen is 0.5~2mm.
In order to obtain the effect of more preferable crushing residua, the inwall of the pump case 8 before broken blade 4 in breaker
On be additionally provided with and import baffle plate 6, the broken blade 4 that rotates cooperates when the importing baffle plate is with working.
The quantity for importing baffle plate 6 is a piece of, can also increase the quantity for importing baffle plate 6 according to the needs of crushing effect.
Embodiment 2：
Reference picture 3, breaker are arranged in a hollow cavity 9, and the cavity one end connects with water inlet 5, and the other end passes through pipe
Road 10 is connected with the pump case 8 before impeller 2, and filter screen 3 is connected with the inwall of hollow cavity 9.
In order to obtain the effect of more preferable crushing residua, the hollow cavity 9 before broken blade 4 in breaker
It is additionally provided with inwall and imports baffle plate 6, remaining is the same as embodiment 1.
