Figure 1A is a partial sectional view, shows the washing machine according to first embodiment of the invention.Figure 1B is a cutaway view, shows a pump and a triple valve.Fig. 1 C is a partial sectional view, shows a housing, and the monolithic devices pump wherein is installed.

Washing machine according to first embodiment of the invention comprises: a housing 50 that has door 55 at its top; Washtub 60 with respect to vertical axes predetermined oblique angle θ; The upper end is fixed on the housing 50 and the lower end is fixed on four suspending rod 57 on the washtub 60, and their allow washtub 60 to tilt; And one be arranged on below the washtub 60, is used for rotating the CD-ROM drive motor 75 of the interior bucket (explanation hereinafter) of washtub 60.

Washtub 60 comprises the outer bucket 22 that utilizes suspending rod 57 to be installed on the housing 50 and can tilt, and interior barrel 65 of rotating in the bucket 22 outside when link to each other with CD-ROM drive motor 75, and wherein interior barrel 65 has agitator 66.

The tilt angle theta that the washtub 60 that outer bucket 61 and interior bucket 65 constitute is installed is in the scope of 0 °＜θ＜30 °.

When washtub 60 was obliquely installed, by the interaction between the inclined inner surface of gravity, centrifugal force and interior bucket 65, the current in the interior bucket 65 had unsymmetric form, and the result causes complicated clothing motion, thereby improved detersive efficiency and realize even washing clothes.

From the radially outstanding washtub wheel rim 62 in outer bucket 61 upper ends, thereby carry out centrifuge washing.Wherein, the centrifugal force that bucket 65 rotations produce in utilizing makes water rise along the inner surface of outer bucket 61, and these water and 62 collisions of washtub wheel rim and jet flow are in interior bucket 65.

Form an osculum 63 on the extreme lower position of bucket 61 bottoms outside, also have a drainpipe 64 that extends to outside the washing machine from osculum 63 to be connected with osculum 63.

A loop hose 70 extends to the upper end of interior bucket 65 from the front portion of drainpipe 64, so that force water to circulate between the top of washtub 60 in the bottom of washtub 60.

According to above-mentioned structure, when carrying out washing and rinsing operation, the water of doing washing sprays laundry water and enters interior bucket 65 inside by loop hose 70 circulation from washtub 60 tops.And when carrying out dehydrating operations, laundry water emits by drainpipe 64.

Particularly, loop hose 70 has the circulating line 71 with 61 barrels of wall one of outer bucket, and extends to the lower surface of washtub wheel rim 62.The upper end of loop hose 70 links to each other with nozzle 74 on being fixed to washtub wheel rim 62.

Certainly, circulating line 71 also can be constitutes one with 61 barrels of walls of outer bucket, but moulding and be installed in outer bucket 61 sides separately.

One is used for the triple valve selectively opened and aquaporin that one of loop hose 70 and drainpipe 64 are linked up and is installed in the position of loop hose 70 from drainpipe 64 bifurcateds.One is used to force the pump 73 of water circulation or discharge water to be arranged between osculum 63 and the bifurcation site.

Figure 1B is the cutaway view of expression pump 73 and triple valve 72.Pump 73 is centrifugal pumps, and wherein water enters the center of its impeller 73a.Valve 72 is positioned at the position of loop hose 70 from drainpipe 64 bifurcateds.

Triple valve 72 is the switch aquaporin by this way, promptly utilizes solenoid actuator 72a to come rotary valve 72b.

Like this, pump 73 is forced water circulation by loop hose 70 and circulating line 71, and forces the water discharging by drainpipe 64.

Fig. 1 C is a cutaway view, shows the situation that a monolithic devices pump is installed.In monolithic devices pump 80, centrifugal pump 83 is connected by single-motor axle 82 each other with axial-flow pump 84, works together.Produce to suck and blowdown presssure in centrifugal pump one side when monolithic devices pump 80 is rotated in the forward, suck and blowdown presssure and produce in axial-flow pump one side during reverse rotation.

If loop hose 85 is connected the laundry water that circulates with centrifugal pump one side, drainpipe 86 is connected with axial-flow pump one side so.

In this case, when monolithic devices pump 80 was rotated in the forward, owing to produce pressure in centrifugal pump one side, the water of therefore doing washing flow to the top of washtub 60; And when 80 reverse rotations of monolithic devices pump, owing to produce pressure in axial-flow pump one side, the water of therefore doing washing is discharged into the outside.

When using monolithic devices pump 80, triple valve is unnecessary, and this is different from the embodiment that triple valve is used in the front.Draw side flexible pipe 87 for two and be connected with the bottom of outer bucket 61 respectively, perhaps an independent flexible pipe that is connected with the bottom of outer bucket 61 is separated into two and draws side flexible pipe 87.

On the other hand, do not adopt the centrifugal pump of Figure 1B and the monolithic devices pump of Fig. 1 C, but a loop hose is connected with outer barrel bottom respectively with a drainpipe, and a circulating pump and a draining pump are respectively installed on loop hose and the drainpipe.

The operation of the washing machine of first embodiment is as described below.

When washing machine started, laundry water was elevated to suitable water level in washtub 60.At this moment, owing to washtub 60 tilts, so washtub 60 is asymmetric with respect to vertical axes.

Under this state, when CD-ROM drive motor 75 work, interior bucket 65 rotations.Because interior bucket 65 tilts with respect to vertical direction, by the interaction between the inclined inner surface of gravity, centrifugal force and interior bucket 65, water forms current of complex form.

In addition, because the agitator 66 in the bucket 65 tilts with respect to vertical axes in being installed in, therefore produce power and centrifugal force upwards, thereby produce secondary current with asymmetric complex form.

When interior bucket 65 with greater than the speed rotation of predetermined speed the time, because outer bucket 61 rotations and can effectively washing.That is to say that owing to produce complicated current along the jet water stream of outer bucket 61 inner surface water level raisings in interior bucket 65 in interior bucket 65 and simultaneously, therefore the friction between laundry water and clothing increases, scourability is improved.

In addition, when pump 73 work, laundry water can be by loop hose 85 circulations, and in nozzle 74 and jet flow water are sprayed onto together in the bucket 65, thereby the raising detersive efficiency.

In a word, when the washing machine that utilizes first embodiment washs,, produce complicated clothing motion because interior bucket 65 tilts.Can realize simultaneously centrifuge washing that causes by interior bucket 65 rotations and the circulation cleaning that causes by pump 73 work.As a result, owing to produce minimum symmetric(al) flow, evenly friction between laundry water and the clothing, thus prevented entanglement between the clothing, and effective washing clothes.

Simultaneously, in rinse cycle, the operation of bucket 65 inside caused optimizing effect in laundry water was sprayed onto from interior bucket 65 tops.That is, in the prior art, rinse cycle is that the stirring rinsing that bucket 65 rotations cause in utilizing is carried out.Carry out together and the rinsing here utilizes centrifugal rinsing and stir rinsing, in centrifugal rinse cycle, bucket 65 inside in laundry water is sprayed onto from interior bucket 65 tops.Like this, the wash effect of clothing significantly improves.

And because centrifugal rinsing and stirring rinsing can be carried out by this way: when interior bucket 65 tilted, water can be from interior bucket 65 bottom cycle to interior bucket 65 tops.Therefore, the wash effect that can use relative more a spot of water to realize.

That is, when rinsing was carried out in the stirring rinsing that bucket 65 rotations produce in utilizing, water will supply to the height of clothing, and after this, the frictional force that rinsing is subjected to doing washing between water and the clothing influences.On the other hand, because centrifugal rinsing and stirring rinsing are carried out together, therefore can use the water of relatively small amount to carry out the clothing rinsing effectively.Wherein, when interior bucket 65 tilts, bucket 65 inside in water is sprayed onto from interior bucket 65 bottom cycle to interior bucket 65 tops and from the top.

Thereby, for example, use 160 premium on currency if stir rinsing, for stirring and centrifugal rinsing, 50 premium on currency are just enough so.In addition, utilize these water, rinse efficiency can improve 10%.

Because of using the water of relatively small amount, so supply water and the shortening of water discharge time cycle, shorten the whole washing cycle of clothing, perhaps significantly increases wash effect by increasing the rinsing number of times.
