The flow path that washing water flows through double shrouded wheel is that washing water flows successively through wheel cap centre bore, the leaf of double shrouded wheel Runner is taken turns, washing water flows through pressure inner cavity and pump out from water from water ring one, water ring two, washing water is pooled between two neighboring blade Water pipe discharge.Washing water flows to pressure inner cavity between double shrouded wheel right end face and one left end face of variable diameter end plate of shell two During, cross section of fluid channel is gradually increased, and makes washing water smooth transition during flowing through double shrouded wheel and pressure inner cavity, respectively Kind loss is small, operational efficiency is high.

After washing water emptying in water tub of washing machine, portion of air enters impeller channel, the impeller in impeller channel When runner liquid level is located between the radially-outer surface and inner radial surface of blade, the blade of double shrouded wheel pushes washing water to generate The decline of water delivery pressure, when certain impeller channel liquid level in a flash in impeller channel is located at blade radial outer surface, blade is pushed and is washed The water delivery pressure for washing water generation is zero, and under the effect of drainpipe static pressure, impeller channel liquid level can return to the radial appearance of blade Between face and inner radial surface, water delivery pressure and drainpipe static pressure is made to reach equilibrium state.Due to draining pump motor speed When the water delivery pressure fluctuation within a narrow range that fluctuation or other factors cause the blade of double shrouded wheel that washing water is pushed to generate, impeller stream Washing water in road between two neighboring blade flows into water ring one, water ring three, and a part of washing water of water ring three crosses enclosed leaf The wheel cap inner radial surface of wheel, washing water again flow into the water ring in impeller channel between two neighboring blade from wheel cap centre bore In, impeller channel liquid level maintains equilibrium state.In above process, into the portion of air and water ring in impeller channel One, always with double shrouded wheel synchronous rotary, the blade of double shrouded wheel will not pat washing water and air always for water ring two, water ring three Between liquid level generate vibration and noise.

Washing machine use finishes, and extracts hose plug, the drainpipe import of washing machine sewer pipe lower end to drainpipe overflowing liquid The remaining washing water of washing machine drainage tube cavity flows successively through pumping line, presses inner cavity, shell inner cavity two, shell between position Inner cavity one, pump drain pipe are discharged from pumping drainage hose.

When the draining pump operation washing water from double shrouded wheel radial outside flow into press inner cavity during, cross section of fluid channel It is gradually increased, makes washing water smooth transition during flowing through double shrouded wheel and pressure inner cavity, the small, operational efficiency of various losses It is high.In washing machine washing water emptying after, into impeller channel air and water ring always with double shrouded wheel synchronous rotary, close The blade of formula impeller will not pat the liquid level between washing water and air always and generate vibration and noise.The air that washing water is swept along The low-pressure area being pooled at double shrouded wheel axis flows back in water tub of washing machine from the central tube of filter, sweeps along washing water Air will not be gathered in impeller channel, it is ensured that the draining pump even running.

Referring to Fig.1, the use process of Fig. 2, Figure 21, Figure 23, the draining pump are:

When the draining pump is applied to upper drain washing machine system, the water feeding of water pump of the case member of horizontal type water-ring draining pump 101 Draining pump connecting tube 104, the water pump of case member are installed between pipe 6 and the steel ladle outlet pipe 105 of water tub of washing machine 108 Outlet pipe 9 is connected with the drainpipe import of 106 lower end of washing machine sewer pipe, and 106 middle section of washing machine sewer pipe is bent up Song forms drainpipe overflow liquid level 110 in 106 inner cavity of washing machine sewer pipe in knee.Washing in water tub of washing machine 108 After water emptying, drainpipe import to the remaining washing water in 106 inner cavity of washing machine sewer pipe between drainpipe overflow liquid level 110 can not Discharge, the washing water fluid column generate drainpipe static pressure.

When filling the water into water tub of washing machine 108, the washing water in water tub of washing machine 108 flows successively through steel ladle water outlet Pipe 105, draining pump connecting tube 104, pump water inlet 6 enter shell inner cavity 1, and washing water flows successively through the sieve of filter 1 again Hole 72, baffle plate diversion hole 35 enter shell inner cavity 2 23, and washing water flows successively through again presses inner cavity 24, pumping line 9, laundry Machine drainpipe 106, steel ladle liquid level 109 are equal with the liquid level in washing machine sewer pipe 106.When steel ladle liquid level 109 is high When drainpipe overflow liquid level 110, a part of washing water is discharged from the drainpipe outlet 107 of washing machine sewer pipe 106.

After washing of drum type washing machine drain and dry draining when, starting draining pump motor, motor stator subassembly 102 with turn The interaction of rotor permanent magnet 10 of subassembly generates electromagnetic torque, and rotor part drives double shrouded wheel 19 to rotate, double shrouded wheel 19 blade 83 pushes washing water to generate water delivery pressure, and washing water is discharged from the pumping line 9 of horizontal type water-ring draining pump 101, Horizontal type water-ring draining pump 101 is the washing water in water tub of washing machine 108 from the drainpipe outlet 107 of washing machine sewer pipe 106 Discharge, steel ladle liquid level 109 highly decline.In the process, in washing water button and coin foreign matter by the sieve pore 72 of filter 1 It intercepts, hair foreign matter is wrapped in 70 outer surface of central tube of filter 1 in washing water.In enclosed leaf when double shrouded wheel 19 rotates Generation low-pressure area at 19 axis, low-pressure area of the collect air that washing water is swept along at 19 axis of double shrouded wheel are taken turns, cocurrent is passed through The central tube 70 of filter 1 is pooled to the top of shell inner cavity 1 from 70 left end face of central tube upwards, finally along water pump into 6 inner cavity top of water pipe flows back in water tub of washing machine 108.Since 70 left end face of central tube is small at a distance from filter end plate 66 In 70 left end face of central tube at a distance from orifice plate 71, the washing water in shell inner cavity 1 enters from the sieve pore 72 of filter 1 The resistance of shell inner cavity 2 23 is small, and the washing water in shell inner cavity 1 enters shell inner cavity two from the central tube 70 of filter 1 23 resistance is big, it is ensured that the air that washing water is swept along can smoothly flow back in water tub of washing machine 108.

The flow path that washing water flows through double shrouded wheel 19 is that washing water flows successively through the wheel cap center of double shrouded wheel 19 Hole, impeller channel 112, washing water flow through from water ring 1, water ring 2 94, washing water is pooled between two neighboring blade 83 Inner cavity 24 is pressed to be discharged from pumping line 9.Variable diameter end plate one 39 of the washing water from 19 right end face of double shrouded wheel and shell 2 18 It is flowed between left end face during pressing inner cavity 24, cross section of fluid channel is gradually increased, and washing water is made to flow through double shrouded wheel 19 Smooth transition during pressure inner cavity 24, various losses are small, operational efficiency is high.

After washing water emptying in water tub of washing machine 108, portion of air enters impeller channel 112, impeller channel 112 In impeller channel liquid level 93 when being located between the radially-outer surface and inner radial surface of blade 83, the blade 83 of double shrouded wheel 19 The water delivery pressure decline for pushing washing water to generate, certain impeller channel liquid level 93 in a flash in impeller channel 112 are located at blade 83 When radially-outer surface, the water delivery pressure that blade 83 pushes washing water to generate is zero, under the effect of drainpipe static pressure, impeller channel Liquid level 93 can return between the radially-outer surface and inner radial surface of blade 83, and water delivery pressure is made to reach flat with drainpipe static pressure Weighing apparatus state.Since the fluctuation of draining pump motor speed or other factors cause the blade 83 of double shrouded wheel 19 to push washing aquatic products When raw water delivery pressure fluctuation within a narrow range, the washing water in impeller channel 112 between two neighboring blade 83 flow into water ring 1, Water ring 3 91, a part of washing water of water ring 3 91 cross 82 inner radial surface of wheel cap of double shrouded wheel 19, and washing water is from wheel cap Centre bore again flows into the water ring in impeller channel 112 between two neighboring blade 83, and impeller channel liquid level 93 maintains balance State.In above process, into the portion of air and water ring 1, water ring 2 94, water ring 3 91 in impeller channel 112 Always with 19 synchronous rotary of double shrouded wheel, the blade 83 of double shrouded wheel 19 will not pat the liquid level between washing water and air always Generate vibration and noise.

Washing machine use finishes, and extracts hose plug 99, and drainpipe import to the drainpipe of 106 lower end of washing machine sewer pipe overflows The remaining washing water in 106 inner cavity of washing machine sewer pipe flows successively through pumping line 9, presses inner cavity 24, is outer between flow liquid position 110 Shell inner cavity 2 23, shell inner cavity 1, pump drain pipe 20 are discharged from pumping drainage hose 100.

When the draining pump operation washing water from 19 radial outside of double shrouded wheel flow into press inner cavity 24 during, runner Section is gradually increased, make washing water flow through double shrouded wheel 19 and pressure inner cavity 24 during smooth transition, it is various loss it is small, Operational efficiency is high.In washing machine washing water emptying after, into impeller channel 112 air and water ring always with double shrouded wheel 19 synchronous rotaries, the blade 83 of double shrouded wheel 19 will not pat the liquid level between washing water and air always and generate vibration and make an uproar Sound.Low-pressure area of the collect air that washing water is swept along at 19 axis of double shrouded wheel flows back to laundry from the central tube 70 of filter 1 In machine steel ladle 108, the air for sweeping along washing water will not be gathered in impeller channel 112, it is ensured that the draining pump is steadily transported Row.
