That is, washing machine of the present invention comprises: first laundry processes makes water infiltrate clothing by centrifugal force; Second laundry processes makes water attack knit clothing when water falls into rotary barrel 3.First and second laundry processes repeats as a series of circulations.Laundry also can impact clothing by impeller 4 rotations and further carry out.

Simultaneously, even between delivery period, clothing also can be caught by net 11, can not be projected into bung more than 5.Therefore, the water that flows into by water supply pipe 8 can directly not impact clothing, thereby water can not be splashed to above the bung 5.That is, net 11 has prevented that water from overflowing bung 5 during the process of water supply process and infiltration clothing.

Fig. 2 is the upward view of bung depicted in figure 1.

With reference to figure 1, bung 5 provides a substructure, and this structure can guide fully from the water of outer bucket 2 and flow directly into rotary barrel 3.

At length, bung 5 is provided with first guide rib 51 and second guide rib 52 in its underpart.First guide rib 51 and second guide rib 52 form the layout of symmetry.Can clockwise and be rotated counterclockwise because rotary barrel 3 is designed to be, thereby preferably first guide rib 51 and second guide rib 52 be made the mutual shape that tilts with relative direction.

Equally, bung 5 also provides a drowning guiding rib 55, is used for guiding the water that has been changed direction by first guide rib 51 to flow to the clothing that is contained in rotary barrel 3.Drowning guiding rib 55 forms along the inner periphery of bung 5.Bung 5 also provides an anti-scattered rib 54 in the bottom, be used for preventing that the water that is directed to first guide rib 51 and drowning guiding rib 55 from scattering.

When the water that has been changed direction by first guide rib 51 collides when falling into water guiding rib 55, for the water that makes such formation splashes minimumly, bung 5 is provided with first hole 56.This first hole 56 is processed to form the junction at first guide rib 51 and the guiding rib 55 that falls into water.

When the water that has been changed direction by second guide rib 52 collides when falling into water guiding rib 55,, also be provided with second hole 57 on the bung 5 for the water that makes such formation splashes minimumly.This second hole 57 is made in the junction of second guide rib 52 and drowning guiding rib 55.

In order to prevent that first guide rib 51 and second guide rib 52 be out of shape because of the whirlpool that forms in the process of water guide, bung 5 also provides the ribs of a plurality of binding first guide rib 51 and second guide rib 52.

Simultaneously, net 11 be formed on water supply pipe 8 below, prevent that clothing is projected into bung more than 5.Net 11 is arranged on the zone line of bung 5.Between net 11 and bung 5, form an open gap 14,, can prevent that also sealing overflows net 11 even supply big water gaging at short notice.That is, supplying water circulation or infiltrate clothing cycle period, though in the short time to the big water gaging of net 11 supplies, water can not overflow bung 5 yet, but falls into outer bucket 2 by open gap 14.

Fig. 3 is the enlarged perspective of washing machine major part depicted in figure 1.

With reference to figure 3, rotary barrel 3 and the bung 5 that is formed on rotary barrel 3 tops are as shown in the figure.Net 11 is formed on the unlatching mouth of bung 5.Open gap 14 is formed between the inner periphery of net 11 and bung 5, prevents overflowing of washings.

Net 11 designs make that water can be through being formed on a plurality of sieve apertures on the net 11.When the clothing 3 li of rotary barrels was risen by the water holder, net 11 compressed clothing, makes it can not give prominence to bung 5.In order to prevent directly to clash into clothing by the water of water supply pipe 8 supply, net 11 be arranged on water supply pipe 8 under.

Though net 11 forms integral body with bung 5, the present invention does not limit therewith.Net 11 can be made independent parts, can with bung 5, rotary barrel 3, outer bucket 2 in any one be assembled together.Yet, most preferred, net 11 is assemblied in the inner periphery of bung 5, like this, net 11 can be installed in water supply pipe 8 under.

And each sieve aperture of net 11 is enough little to clothing, makes it to give prominence to bung 5, but water is also wanted enough big, makes it and can not spill.

Second embodiment

Fig. 4 has described washing machine according to a second embodiment of the present invention.

Except the structure of net, present embodiment is all identical with first embodiment.The net 21 of present embodiment also is formed on the bung 5, and stretches out from its inner periphery, and is installed in water supply pipe 8 belows.Each sieve aperture of net 21 and first embodiment's is comparatively speaking relatively large.Therefore, the open gap even without in first embodiment (with reference to figure 3 14) can prevent that also washings from overflowing.

The 3rd embodiment

Fig. 5 has described the washing machine of a third embodiment in accordance with the invention.

With reference to figure 5, except the structure of net, present embodiment is all identical with first embodiment.The net of present embodiment is designed to have the sieve aperture of arranging that is formed by a plurality of beams on same direction, that is, and laterally or vertically.Yet the net of first embodiment is designed to have the rectangle sieve aperture of all arranging horizontal and vertical that is formed by a plurality of beams.The open gap 34 that provides can prevent that sealing overflows.

The 4th embodiment

Fig. 6 has described the washing machine of a fourth embodiment in accordance with the invention.

With reference to figure 6, washing machine of the present invention is provided with a rotary barrel 3 as the washing machine of first embodiment, net 41 and open gap 44.And washing machine also comprises first,

second electrode sensor

42 and 43 that is installed on the net 41.When contact with clothing arrived first,

second electrode sensor

42 and 43, first,

second electrode sensor

42 and 43 was electrically connected, and can detect the height that clothing rises to net 41 by them.When detecting clothing and rise to the height of net 41, the rotating speed of rotary barrel 3 slows down or the rotation of rotary barrel 3 is stopped temporarily, thereby has prevented that water from spilling.

The operation of first, second electrode sensor will be described in greater detail below.

Washings rise brokenly or fluctuate during supplying water circulation and wash cycle, and perhaps when contact with clothing arrived the long side of net 41, first,

second electrode sensor

42 and 43 can be electrically connected.

Because the former is a normal condition, can ignore.That is, rise above the state that preestablishes height in order to detect clothing 48,

electrode sensor

42 and 43 designs are used for detecting a small amount of washings that touch net 41 small sizes, but can detect Continuous Contact net 41 large-area washings.That is, when the contact with clothing of outstanding bung 5 to the enough big part of net 41 long parapodums and long enough during with the change resistance value,

electrode sensor

42 and 43 can detect

clothing.Electrode sensor

42 and 43 prevents that by the clothing that detects outstanding bung 5 sealing spills.

At length, supplying water cycle period, even the outstanding bung 5 that does not have net of clothing, clothing is knit in water attack, also can not spill.Yet during infiltrating wash cycle, washings impact to rise and surpass the clothing of predefined height.In this case, because water may spill, should detect the rising of clothing, the rotating speed that can control washing machine like this splashes to prevent water.

Fig. 7 is the block diagram of the operation of explanation the 4th embodiment.

With reference to figure 7, provide the test section 45 that is formed on a long side, limits by electrode sensor 42 and 43.The signal that is produced by test section 45 is sent to control assembly 46.According to 45 signals that send from the test section, control section 46 judges whether the clothing rising surpasses predefined height.When control section is judged clothing and rise to be surpassed the operation of predefined height, slow down rotating speed or stop wash cycle of motor-driven part 47.

That is, test section 45 produces detection signal, and signal is sent to control section 46.Control section 46 according to from the test section 45 signals that send judge that clothing rises whether above predefined height.When control section is judged clothing and rise to be surpassed predefined height, control section 46 control motor-driven parts 47, its slow down rotating speed of motor or stop the rotation of motor like this, from then on anti-sealing splashes.

Fig. 8 has described when the state of contact with clothing during to the long side of the net of describing in Fig. 6.

In state as shown in Figure 6, because net 41 is caught clothing, the problem that washings splash can not occur.

Yet in state as shown in Figure 8, clothing is not caught by net 41, thereby outstanding bung 5.That is, because, may during wash cycle, be given prominence to net 41 by the clothing that net 41 is caught, and touch the long side of net 41 supplying water cycle period.

In this case, clothing 48 touches the

sensor

42 and 43 of the long side that is installed in net 41, so pre-set detection signal is sent to control section.The signal controlling driver part that control section sends according to detecting sensor, the revolving force of washing machine weakens like this, thereby has stoped spilling of water.And, for rearranging clothing, the user cannot not make it outstandingly bung 5, control section bucket 3 the rotation of can stopping the rotation.

In the meantime, and be easy to the to wear and tear inner surface of net 41 of the frictional force between the clothing.That is because during wash cycle the inner surface of net 41 friction clothing, when washing machine is long-time use after, it can be worn.When the inner surface of net 41 is worn, it becomes coarse, causes the damage of clothing.

In order to prevent that clothing and net are worn, the surface of net 41 preferably covers the layer of metal material, with smooth metal surface as protected mode.This protected mode can be metal ribbon or specially prepare, be assemblied in the metal material on the net 41.

The 5th embodiment

Except the structure that a kind of wearing and tearing that prevent net and clothing also are provided, present embodiment is all identical with the 4th embodiment.

Fig. 9 is the perspective view of barrelhead of washing machine according to a fifth embodiment of the invention.Figure 10 is along the profile of direction shown in the A-A line among Fig. 9.

With reference to figure 9 and Figure 10, net 51 is formed on the part inner periphery of bung.Because the inner often contact clothing of net 51, the over cap 60 that is used for catch net 51 the inners covers the inner of net 51.

Over cap 60 is by in the inner 52 that is buckled in net 51.That is, when over cap 60 strains, be stuck in the inner 52 of net 51.Therefore, over cap 60 is preferably made with elastomeric material.Over cap 60 can link with screw and hook spare and inner 52.Yet in this case, screw and hook spare can make appearance ugly, and make and the damage of clothing during wash cycle disfeature simultaneously.Therefore, preferred over cap 60 is by being clasped and inner 52 bindings.

At length; over cap 60 comprises: one is used for the top standing part 61 that links with inner 52 upper end; 62, one of a linking portion that are used for linking with inner 52 bottom has slight bending, can make linking portion 62 be easy to insert the insertion end part 63 of inner 52 bottoms.Over cap 60 is by making as the elastomeric material of elastoplast, stainless steel and elastic caoutchouc.

When over cap 60 was made by elastoplast and elastic caoutchouc, it wore and tore easily.In this case, need to change a new elastomer cover.Therefore, the most handy stainless steel is made over cap.

At length, the inner 52 of net 51 comprises: 53, one 54, one on second hook that link with linking portion 62 of first hook that link with standing part 61 be formed on first hook 53 neighbouring, be used for preventing the 3rd hook 55 that over cap 60 is separated.

Over cap 60 will be described below with the binding process of the inner 52 of net 51.

Standing part 61 links with first hook 53 earlier, and linking portion 62 is by being clasped and 54 bindings of second hook.At this moment, because insertion end part 63 is by slight bending, thereby linking portion 62 produces strains, and is installed on second hook 53.And the 3rd hook 55 has supported standing part 61, can not make it to separate with first hook 53.

Figure 11 is the perspective view of over cap as shown in Figure 9.

With reference to Figure 11, the standing part 61 of circumflexion is formed on the upper part of over cap 60, so can be fixed on the upper limb of the inner 52 of net 51.The linking portion 62 that can produce strain is formed on the end portion of over cap 60, so can be fixed on the downside of the inner 52 of net 51.Insertion end part 63 can be made linking portion 62 insert the bottom of the inner 52 at an easy rate by slight bending.Equally, when over cap 60 inserted net 51, insertion end part 63 prevented the generation of scratch phenomenon.

In structure described above, exotic may be accumulated between the ledge of net 51, particularly between the first, the 3rd hook 53 and 55.To the user, the exotic of removing accumulation in the net 51 is pretty troublesome.

The 6th embodiment

Except the structure of inner end of net, a plurality of parts of the 6th embodiment are all identical with the 5th embodiment.That is, prevent that by the structure that changes the inner end of netting exotic from being accumulated.

Figure 12 is the profile of net, has described according to the sixth embodiment of the present invention, has illustrated that over cap is fixed on the inner end of net.

With reference to Figure 12, first hook 73 is formed on the top of the inner end 72 of net 71, and second hook 74 is formed on the bottom of the inner end 72 of net 71.Over cap 60 has the same structure with the 5th embodiment.

The binding operation of over cap 60 is described below, first hook 73 is located like this, makes a standing part hook first hook 73, and linking portion 62 is snapped on second hook 74 then.

By top structure, prevented the accumulation of exotic between first hook (with reference to the sequence number 53 of Figure 10) and the 3rd hook (with reference to the sequence number 55 of Figure 10).Equally, by strengthening the size that standing part is 61 that reserve in advance, be different from the 5th embodiment, can prevent that over cap 60 from easily being separated.In view of the above, owing to the shortcoming of saving the 3rd hook 55 of the 5th embodiment is overcome at an easy rate.

As above describe according to of the present invention, because net is formed on the bung, clothing can not given prominence to bung, can prevent that therefore the water during supply water circulation and wash cycle from spilling.Therefore, can avoid contingency by the caused any easy ignorance of water that spills.

And even when clothing is given prominence to bung, detection components detects this situation, the rotating speed of control drive motors, thus prevent splashing of sealing.

And, because having prevented net, over cap is worn, the clothing of contact net also is difficult for being damaged.And each angle of over cap is prevented that by slight bending clothing is damaged.

It will be apparent to those skilled in the art that, can do various improvement and distortion the present invention.Therefore, improvement of the present invention and the distortion in the scope that falls into additional claim and be equal to them contained in the present invention.
