Abstract
The utility model relates to a water pump for a dishwasher. The utility model which is a water pump with a new structure is arranged in the dishwasher for realizing water discharge that is switched in two directions. A motor assembly adopts a motor which runs with a single-phase capacitor and works in double directions. An inner cavity of a pump body is divide into three chambers, upper impellers, upper water discharge openings, lower impellers, and lower water discharge openings are respectively arranged in an upper water discharge chamber and in a lower water discharge chamber, and a plurality of water inlets are arranged in an isolating chamber. The utility model which has the advantages of compact structure, small size, little space occupation, and low cost is arranged in the dishwasher for increasing effective washing space and realizing water discharge in the two directions.
Description
The utility model relates to a kind of improvement of use in dishwasher water pump mechanism, is a kind of water pump that can realize the new structure of 2 directions switching drainings, is a kind of dishwasher water pump specifically.
Water pump is generally unidirectional running, can only realize a direction draining, can not realize that 2 directions switch drainings, for can 2 direction draining, just needs 2 motors drag 2 water pumps, should occupy big space, the cost of increasing input again.
The utility model purpose is to overcome the shortcoming in the above-mentioned technology, proposes a kind of dishwasher water pump of new structure, only need adorn a motor in the pump housing, just can realize double drainage, can make compact structure, and it is little to take up room, and reduces cost.
The utility model purpose is realized by following technological scheme: this dishwasher water pump, on the pump housing top fan guard is housed, fan is housed in the fan guard, below fan, with on the same rotatingshaft of fan motor assembly is housed, it is characterized in that motor assembly adopts single-phase capacitance operation two-way working motor, pump housing inner chamber is divided into three chambers: go up drip chamber, following drip chamber and the isolation ward in the middle of them, in the last drip chamber impeller is housed, in the following drip chamber impeller is housed down, last impeller all is contained on the same rotatingshaft with motor assembly and fan with following impeller, be positioned at the below of motor assembly, respectively have one in last drip chamber and the following drip chamber and go up drain opening and following drain opening, isolation ward has a plurality of water intakes.
Last drip chamber is assembled by the top of upper pump casing, water proof dish, and the last impeller that is contained on the rotatingshaft is arranged in the last drip chamber, and the Centrifugal water pump blade is housed on the last impeller, together is made into charging pump, and the charging pump water outlet is the scroll casing shape water channel.On last impeller water guiding ring being housed, is water intake around the water guiding ring.Water is entered by the isolation ward water intake, and after the water intake around the process water guiding ring entered charging pump vertically, last impeller was to clockwise rotate, and water is thrown away through blade, has obtained speed energy and pressure energy, discharged through the scroll casing shape water channel of charging pump.Because sectional area enlarges gradually, speed can reduce, and pressure can raise, and discharges high pressure water by water outlet, carries out towards the dishwashing tableware.
Following drip chamber is made up of the bottom of lower pump body, water proof dish, in the following draining impeller is housed down, and two kinds of blades are housed on the following impeller, when rotatingshaft rotates counterclockwise, last impeller, impeller reverses down, charging pump idle running, following water pump is intake by water intake, water flow to the M place, and the cross section is less, flow to the N place, the cross section is bigger, flow velocity reduces, and pressure raises, and discharges high pressure water to reversing water outlet.When water intake is closed, then can be with outside the addle discharge machine after washing the dishes.
On the rotatingshaft of following impeller bottom, lock washer is installed, prevents that impeller is upper and lower mobile.Be connected mutually by end tooth between last impeller, the following impeller.The motor that this water pump is joined is a single-phase capacitance operation two-way working motor, adopts double winding.In forward when running,, a winding is as main winding in the motor, and another winding is as secondary winding, and with electric capacity priming is arranged, and after the steady running, electric capacity is again as operation electric capacity.When commutating to b, carry out antiport, two winding roles are just in time opposite when commutating to a.
The utility model advantage is a compact structure, and institute takes up space little, only adorns a motor in the pump housing, just can realize double drainage, reduces cost, and is placed in the dishwasher, can increase effective scrubbing space.
Embodiment of accompanying drawings:
Fig. 1 is a kind of dishwasher water pump structure figure,
Fig. 2 is partly partial structurtes figure of impeller,
Fig. 3 be D to view,
Fig. 4 is impeller and water intake under the C-C face, water outlet structural representation,
Fig. 5 is impeller and a clockwise water outlet structural representation on the B-B face,
This dishwasher water pump is equipped with fan guard 1 on pump housing top, fan 5 and fan back-up ring 6 is housed in the fan guard below the fan with on the same rotatingshaft 21 of fan motor assembly 7 is being housed, and motor assembly adopts single-phase capacitance operation two-way working motor.Pump housing inner chamber is divided into three chambers: go up drip chamber, following drip chamber and the isolation ward in the middle of their.Impeller 11 is housed in the last drip chamber, in the following drip chamber impeller 16 is housed down, last impeller and following impeller all are contained on the rotatingshaft 21, are positioned at the motor assembly below.Last drip chamber mainly is assembled by the top of upper pump casing 22, water proof dish 15, and the water outlet of charging pump is the scroll casing shape water channel, is discharged tablewares such as high pressure water washing bowl dish by water outlet.Water enters isolation ward by 6 water intakes of water proof dish 15, enters charging pump through the water intake around the water guiding ring 18 again, throws away via last impeller.The effect of water proof dish 15 helps the reasonable distribution of upper tank and lower header current balance and current, adjusts the water flow pressure between two pumps, bleeds or spilling water from the drain opening of lower header when preventing to clockwise rotate.
When rotating counterclockwise impeller, following drip chamber is a working pump, owing to the centrifugal action and lower pump body 23 effects of impeller 16 down, at the drain opening generation high-pressure water flow of following drip chamber, the water in the pump constantly can be discharged from the drain opening of following drip chamber.Loosening for preventing impeller, below impeller down, locking pad 17 is housed on the rotatingshaft, upper pump casing 22 and lower pump body 23 joints are equipped with O RunddichtringO 10.For the water pump packing performance is good, double-lipped water seal 9 also is housed, water pump packing ring 19, water pump cover 14 and vibration damping leg 13 are equipped with in the bottom.
