Abstract
The invention relates to a permanent-magnetic draining pump, which is particularly used for a domestic washing machine and comprises a pump casing and a motor. A shaft hole, a water inlet and a water outlet are arranged in the pump casing, an output shaft of the motor extends into the pump casing via the shaft hole, and an impeller is disposed in the pump casing and connected with the output shaft of the motor. The permanent-magnetic draining pump is characterized in that a through hole is arranged on one surface, which is perpendicular to the pump casing, of the output shaft of the motor, an outer extending barrel is disposed on the outer side of the through hole, a knob is arranged at the outer end of the outer extending barrel, a filter cartridge is arranged in the outer extending barrel on the inner side of the knob, one end of the filter cartridge is connected with the knob, and the other end of the filter cartridge is abutted to the peripheral edge of the through hole. The water inlet is positioned on a side wall of the outer extending barrel. By the aid of the permanent-magnetic draining pump, the failure rate of the washing machine can be greatly reduced.
Description
Technical field
The present invention relates to a kind of water pump.Specifically, be magneto draining pump on the domestic washing machine.
Background technique
All know in the washing machine manufacturing, all be provided with draining pump on the washing machine.Traditional draining pump comprises pump case and motor, and axis hole, water intake and water outlet are arranged on the pump case, and the output shaft of motor stretches in the pump case through axis hole, and impeller is arranged in the pump case, and said impeller links to each other with the output shaft of motor.When program of completion needs draining in the washing machine running; When coming the starting electrical machinery rotation by control program; Entery and delivery port on the pump case is opened, and the current in the washing machine get into behind water intake in the pump case, discharges outside from water outlet through the impeller rotation.Because the water inlet of this draining pump is on pump case, during washing machine drainage, the water in the washing machine directly gets in the pump case; After foreign material such as fiber that drops in the washing clothes and coin get into pump case; Not only the washing machine drainage mouth can be stopped up, also impeller can be damaged, therefore; Adopt the washing machine of traditional draining pump, rate of fault is higher.
Summary of the invention
The problem that the present invention will solve provides a kind of magneto draining pump.Adopt this magneto draining pump, can reduce the washing machine rate of fault greatly.
For addressing the above problem, take following technological scheme:
Magneto draining pump of the present invention comprises pump case and motor, and axis hole, water intake and water outlet are arranged on the pump case, and the output shaft of motor stretches in the pump case through axis hole, and impeller is arranged in the pump case, and said impeller links to each other with the output shaft of motor.Its structural feature is that the pump case vertical with the output shaft of motor simultaneously gone up through hole, and there is overhanging tube in the through hole outside, and there is knob the outer end of overhanging tube, in the overhanging tube of knob inboard cartridge filter is arranged, and cartridge filter one end links to each other with knob, and the periphery of the other end and said through hole offsets.On the sidewall of overhanging tube water intake is arranged.
Wherein, disk and outer disc in said cartridge filter contains have the net tube between inside and outside disk, and interior disc centre has through hole, and said net tube two ends form as one with interior disk and outer disc respectively.Water intake on water outlet on the pump case and the overhanging tube is in relative both sides respectively.
There is internal thread the outer end of overhanging tube, and outside thread is arranged on the knob, and knob screws in the outer end of overhanging tube by the internal thread of outside thread on it and overhanging tube outer end.
Take such scheme, have the following advantages:
Can find out that by such scheme because the pump case vertical with the output shaft of motor simultaneously gone up the processing through hole, there is overhanging tube in the through hole outside; There is knob the outer end of overhanging tube; In the overhanging tube of knob inboard cartridge filter is arranged, cartridge filter one end links to each other with knob, and the periphery of the other end and said through hole offsets.On the sidewall of overhanging tube water intake is arranged.During washing machine drainage; Water in the washing machine gets into the water intake on the overhanging tube sidewall; After the filtration through the net tube; Through hole through net tube inner end gets in the pump case again, and foreign material such as the fiber that drops in the washing clothes and coin are intercepted at outside the net tube, the situation generation that foreign material such as the fiber of having avoided dropping in washed and coin stop up washing machine drainage mouth, damage impeller.Thereby greatly reduce the rate of fault of washing machine.
Description of drawings
Fig. 1 is a magneto draining pump structural representation of the present invention;
Fig. 2 is the cartridge filter schematic perspective view among Fig. 1.
Embodiment
As shown in Figure 1, magneto draining pump of the present invention comprises pump case 2 and motor 1, and said pump case 2 is the approximate circle dish type; Be processed with water outlet 3 on its outer side wall; The center of its one side is processed with axis hole, and its another side is processed with through hole, and the output shaft 12 of motor 1 stretches in the pump case 2 through axis hole.Be provided with impeller 4 in the pump case 2, the center of said impeller 4 is processed with axis hole, and impeller 4 is fixed on the output shaft 12 of motor 1 by the axis hole at its center.Pump case 2 one sides that have through hole are provided with overhanging tube 5, and the inner end of this overhanging tube and the pump case 2 around the said through hole form as one.The outer end of overhanging tube 5 is provided with knob 7, is processed with outside thread on the knob 7, and the outer end of overhanging tube 5 is processed with internal thread, and knob 7 screws in the outer end of overhanging tube 5 by the internal thread of outside thread on it and overhanging tube 5 outer ends.Be processed with water intake 11 on the sidewall of overhanging tube 5.
As shown in Figure 2, be provided with cartridge filter in the overhanging tube 5 of knob 7 inboards, cartridge filter one end links to each other with knob 7, and the periphery of the other end and said through hole offsets.Disk 10 and outer disc 6 in said cartridge filter contains, 6 of interior disk 10 and outer discs are provided with net tube 8, and interior disk 10 centers are processed with through hole 9, and said net tube 8 two ends form as one with outer disc 6 with interior disk 10 respectively.
Water intake 11 on water outlet 3 on the pump case 2 and the overhanging tube 5 is in respectively on the relative both sides.The outer end of overhanging tube 5 is processed with internal thread, is processed with outside thread on the knob 7, and knob 7 screws in the outer end of overhanging tube 5 by the internal thread of outside thread on it and overhanging tube 5 outer ends.
During washing machine drainage, the water in the washing machine through the water intake 11 on overhanging tube 5 sidewalls, again pass through hole 9 on net tube 8 sidewalls and the interior disk 10 after, get in the pump case 2, under the effect of impeller 4, water outlet 3 is discharged.
