Description
The present invention relates to washing machine, particularly the washing machine of the water circulation in the washtub.
Common washing machine is that substrate, water and an amount of washing agent are put into washtub, utilizes the water process that flows, and substrate is applied impulsive force, automatically carries out a series of washing, rinsing and dehydration stroke.
Fig. 1 is the sectional drawing of washing machine in the expression prior art.Fig. 2 is the stereogram of the washtub of this washing machine.As shown in Figure 1, in the existing washing machine, rear side is provided with water-supply valve 12 on housing 10, in housing 10 inside water storage barrel 20 is installed.Trickle ring 22 is installed in the top of water storage barrel 20, accepts the water from water-supply valve 12.Washtub 30 is located at the inside of water storage barrel 20, is made of columnar washtub pedestal 32 and the cylindrical shape washtub body 34 that is assembled on this washtub pedestal 32.Inner peripheral surface both sides at this washtub pedestal 32 are formed into mouth of a river 32a respectively, and washtub body 34 is constituted by several plates 34a.On this plate 34a, form the hole 34b that several are communicated with water storage barrel 20.Balancer 36 is located at the top of washtub body 34, and the side face both sides form mouth of a river 36a respectively within it.
In the inner peripheral surface both sides of washtub body 34, guiding filter 40 is installed respectively.Between washtub body 34 and guiding filter 40, the water route 40a of the water inlet 32a of formation connection washtub pedestal 32 and the delivery port 36a of balancer 36 is installed with filter element 42 on the top of this water route 40a.In the central authorities of washtub body 34, palsating equipment 60 is installed, this palsating equipment 60 is by gear part 52 rotations that are combined on the motor 50.Edge part at this palsating equipment 60 forms several spray-holes 62, in its lower section, is and forms several blades 64 radially.In the bottom of water storage barrel 20, the bubble generator 70 that produces bubble is being set.
Specifically, at the washing stroke of substrate, initial, set required washing function by the user, by the driving force of motor 50, gear part 52 makes palsating equipment 60 rotations, and this rotation forms so-called vortex water flow, simultaneously, these current are raised to the top of palsating equipment 60 by spray-hole 62, produce jet water course, then the driving by bubble generator 70, bubble (being air bubble) is sneaked in these current, carries out the washing of substrate.In addition, by the rotation of palsating equipment 60, after the water inlet 32a of the water of washtub 30 by washtub pedestal 32 enters, by the water route 40a of guiding filter 40, the delivery port 36a of balance between supply and demand device 36.Like this, be given to the water of the delivery port 36a of balancer 36, fall the below from the top of washtub 30, form so-called vertical flowing water.On the other hand, when water supplied to trickle ring 22 by water-supply valve 12, this water was fallen from trickle ring 22 medial margins and is washed in the bucket 30, forms so-called anxious water.
Like this, existing washing machine, the user the bottom of cylindrical shape washtub body 34 be entrenched in cylindrical shape washtub pedestal 32 above, under this state,, be assembled into washtub 30 with pushing such as pressure washtub body 34.But, keep accurate between washtub pedestal 32 and the washtub body 34 in order to make, the internal diameter of washtub body 34 is become the external diameter that is slightly smaller than washtub pedestal 32, so the user when chimeric, considerably note pedestal 32 and body 34, so the packaging efficiency of washing machine is low.
In addition, for the water inlet 32a with washtub pedestal 32 links to each other with the delivery port 36a of balancer 36,, guiding filter 40 is installed, so assembleability reduces more in the inner peripheral surface both sides of washtub body 34.That is, guiding filter 40 must be aligned in the water inlet 32a of washtub pedestal 32 and the delivery port 36a of balancer 36 exactly and install, and, between washtub body 34 and guiding filter 40, can not produce the gap, so, the assembling of guiding filter 40 is complicated, is pretty troublesome thing.Although taked these measures, if when producing the gap between washtub body 34 and guiding filter 40, substrate may be stuck in this this gap, thus the damage substrate.In addition, the water of water route 40a reduces the cycle efficieny of water by this clearance leakage.Because guiding filter 40 is projected into washtub 30 inboards, so substrate can sustain damage when contacting with this guiding filter 40, is perhaps seriously crumpled.
In addition, washtub pedestal 32 and balancer 36, because the formation of water inlet 32a and delivery port 36a, its focus degree reduces greatly.Specifically, washtub pedestal 32 and balancer 36 usefulness resins are made.But, because the water inlet 32a of washtub 32 and the delivery port 36a of balancer 36 form the ditch shape, so, when the moulding of washtub pedestal 32 and balancer 36, become the reason of distortion (for example shrinking).Therefore, the assembling of washtub pedestal 32 and balancer 36 bothers more.
On the other hand, when palsating equipment 60 rotations, blade 64 below spreads water at palsating equipment 60 toward the side, under the centrifugal action of palsating equipment 60, produce flowing of water, after water inlet 32a by washtub pedestal 32 enters water route 40a, rise, to the delivery port 36a of balancer 36 feedwater to the top of water route 40a.But because the water inlet 32a of washtub pedestal 32 forms the structure that is used to assemble guiding filter 40, its complex structure plays inhibition to entering of water.And because the assembled configuration of guiding filter 40, the area of section of water inlet 32a diminishes, and the water yield of going into of water is reduced, and therefore, the cycle efficieny of the water of the water route 40a circulation by guiding filter 40 is low.
Like this, when the cycle efficieny of water was hanged down, the generating capacity of the flowing water that hangs down reduced, and detersive efficiency reduces.For example, by the water route 40a of guiding filter 40, water circulates, and its circulation promotes the dissolving of washing agent.In addition, vertical flowing water has the effect that impacts substrate, can improve detersive efficiency, and, can make the substrate that the is positioned at washtub 30 tops dirt that comes off.But when the cycle efficieny of water reduced, the dissolution rate of washing agent and the detersive efficiency of substrate all reduced, and the dirt of substrate etc. are intactly residual.The dirt of substrate residual state under when washing, be not easy to remove the dirt of substrate, the wash time lengthening also increases the consumption of water.When the water level of washtub 30 hanged down, water rose to the top of water route 40a hardly, and this problem is more serious.
In addition, because the joint construction between the water route 40a of the delivery port 36a of balancer 36 and guiding filter 40, delivery port 36a is positioned at the bottom of the inner peripheral surface of balancer 36, therefore, and when the substrate of volume drops in the washtub 30, the delivery port 36a of balancer 36 is blocked by substrate, can not produce vertical water, and the distance of delivery port 36a and substrate becomes near, the effect of vertical flowing water weakens, and efficient reduces.
In the prior art, make the circulating device of the water of water storage barrel 20 to the feedwater of washtub 30 tops though also develop the driving that utilizes pump (figure does not show), this circulating device will additionally adopt parts such as pump and loop hose, makes the structure of washing machine become more complicated.In addition, the increase of parts reduces assembleability, and has increased manufacturing cost.
In the Japanese kokai publication sho 61-34840 communique, the looping construct that has disclosed water circulation does not protrude in the washing machine of washtub inner peripheral surface.The washtub of this washing machine is made of resin, and in the bottom surface of washtub, forms the ditch of bringing the mouth of a river into.On the outer peripheral face of washing machine, form the vertical water route that links to each other with water inlet by rib in length and breadth, the top in the water route forms and the inner delivery port that links to each other of washtub, and the water route is airtight by the lid that is installed in the washtub outer peripheral face.The delivery port of washtub is provided with outlet pipe, in the place ahead of outlet pipe filter is being set.Be provided with palsating equipment in the ditch of washtub, this palsating equipment is rotated by gear part by the driving force of motor.Below palsating equipment, form several blades radially.
Therefore, when the driving of motor made the palsating equipment rotation, the blade of this palsating equipment produced current, and water enters the water route from the ditch of cask washing by water inlet.Behind the top that is raised to the water route waterborne that has entered this water route, enter washtub inside by outlet pipe.At this moment, the filter that is arranged on outlet pipe the place ahead filters the foreign matter in the water (for example the end of a thread).
But the washtub of above-mentioned existing washing machine is made into ester moulding, so, exist the big problem of washtub weight.For example, resinous washtub, in order to strengthen intensity, its thickness is thicker, will form several ribs at the outer peripheral face of washtub, so, the weight of washing the bar bucket is increased.Especially, owing on washtub, form the some holes that communicate with water storage barrel, so, if the thin thickness of washtub just can not guarantee enough intensity.In addition, along with the increase of this washtub weight, the capacity of motor also will increase, so resin system washtub is not suitable for jumbo washing machine, to motor and geared system effect overload, is the reason that breaks down, and power consumption is increased.In addition, resin system washtub, because of the reason of resin properties, easy deformation (for example shrinking) for example, is not easy to keep the focus degree, produces vibration and noise, and reliability is low.
On the other hand, be formed at water inlet and delivery port on the ditch of washtub, linked to each other by long water route, so it is smooth and easy that the current that enter the water route are not easy to keep, delivery port is confined in the scope in water route to become than ninor feature, and the water yield of water is reduced.Therefore, the cycle efficieny of water is low, and filter efficiency of the end of a thread and detersive efficiency are also low.In addition, owing to outlet pipe to additionally be installed at the delivery port in water route, so assembleability is poor.Moreover, in the place ahead of outlet pipe filter is set, with the substrate input or when taking out in the washtub, this filter is in the way.Therefore use inconvenient.
For this reason, the purpose of this invention is to provide the high washing machine of packaging efficiency.

As Fig. 3, Fig. 5, Fig. 6, Fig. 7 and shown in Figure 9,, carriage 250 is being set with fastener (for example screw) at the centre bore 112 of washtub pedestal 110.State in that the seam portion 152,156 of the 1st and the 2nd plate 140,160 is alternately connected mutually combines it through joint treatment, 3 pairs the 1st and the 2nd plate 140,160 are alternately connected and forms body 130.Like this, body 130 forms slightly cylindrical shape.When washtub pedestal 110 is used resin forming, owing to water inlet 114 forms with the hydroecium 118 of going into of protuberance 116 with being connected, so can prevent distortion (for example shrinking) effectively.Therefore, can critically keep the focus degree of washtub pedestal 110, prevent assembly failure.
As Figure 14 and shown in Figure 15, washtub 100 is that body 130 is assembled into the assembling grove 126 of the protuberance that makes the 1st plate 140 142 that washtub pedestal 110 tops promptly constitute and washtub 100 when chimeric, the top of the protuberance 142 contact guide plates 124 of the 1st plate 140 is guided and chimeric with combination slot 126 naturally.Specifically, the user is deformed into about linearity with the circular shape of the protuberance 142 of the 1st plate 140, be entrenched on the combination slot 126 of washtub pedestal 110, therefore, the easily chimeric outer peripheral face that is assembled in washtub pedestal 110 of body 130.In addition, on the combination slot 126 of washtub pedestal 110 in the chimeric process, the protuberance 142 of the 1st plate 140 is guided plate 124 guidings and is returned to original state at the protuberance 142 of the 1st plate 140.That is, guide plate 124 tilts at a predetermined angle, and the bottom that makes combination slot 126 is expanded out gradually toward top, so, about linearization(-sation) protuberance 142 embed assembling groves 126, be guided plate 124 and guide and be returned to original state.After the protuberance 142 of the 1st plate 140 fully is fitted in the assembling grove 126 of washtub pedestal 110, be bearing in below the body 130 on the supporting jaw 122 of washtub pedestal 110, washtub pedestal 110 and body 130 combinations, the bottom of body 130 is fixed on the outer peripheral face of washtub pedestal 110 by jockey (for example screw).Like this, body 130 is alternately combined by the 1st and the 2nd plate 140,160 of stainless steel, so, washtub 100 in light weight, it is also easy to assemble.
Extremely shown in Figure 29 as Fig. 4, Figure 23, balancer 210 is located at the top of body 130, for the delivery port 220 that makes balancer 210 and outlet 230 link to each other ground connection by chimeric with the water route 144 of protuberance 142, the top of body 130 is fixed on the outer peripheral face of balancer 210 by jockey (for example screw).In addition, on the assembling grove 226 of balancer 210, the handgrip 242 of filter assemblies 240 is being set chimericly.
As Figure 10, Figure 11, Figure 17 and shown in Figure 180, the water route 144 of the 1st plate 140 is airtight by lid 170.The recess 154 of the 1st plate 140 is entrenched in covers on 170 the assembly hole 178, the external screw 194 of screw 190 is passed the cubic hole 156 of the 1st plate 140, four jiaos of hubs 194 of screw 190 are entrenched on the cubic hole 156, can prevent the rotation of screw 190.At this state, the cloudy screw 202 of nut 200 is screwed on the external screw 196 of screw 190, by preventing the rotation of screw 190, can easily carry out fastening effect.The 1st plate 140 and lid 170 fit together securely, and the serration of nut 200 (セ レ-シ ヨ Application) 206 is bearing in and covers 170 outer peripheral face, unclamp to prevent screw 190 and nut 200.Like this, cover 170 by the screw 190 and fastening setting of nut 200, the rib 172,174 of lid 170 and the both side edges portion in water route 144 join and airtight water route 144.Seal 180 keeps the airtight of water route 144, prevents to leak.On the other hand, the head 192 of screw 190 is positioned at the recess 154 of the 1st plate 140, can prevent to protrude in the inner peripheral surface of body 130, like this, can prevent the head 192 damage substrates of screw 190.
As Figure 10 to Figure 13, Figure 18, shown in Figure 30, substrate and washing agent put into the inside of washtub 100 after, set required washing function, from water-supply valve 82 to 92 feedwater of trickle ring.This water falls into washtub 100 inside from the edge of trickle ring 92 inner faces, produce so-called anxious water after, the hole 148,162 by body 130 is stored in the water storage barrel 90.This urgency water impacts substrate from the top of washtub 100, plays clean result, when the rinsing of substrate, has the effect of removing the washing agent foam.
When the driving force of motor 270 was delivered to geared system 260 by power transmission, geared system 260 made the rotational delay of motor 270, made palsating equipment 280 rotations with required rotary speed.So, by the rotation of this palsating equipment 260, producing so-called vertical flowing water simultaneously, below palsating equipment 280,, arrive the top of palsating equipment 280 by squit hole 282 to water generates centrifugal force, produce and spray water.Supply with bubble (being air bubble) simultaneously, carry out the washing stroke of substrate by the driving generation of bubble generator 290.
In addition, by the rotation of palsating equipment 280, after the water in the washtub 100 is gone into hydroecium 118 by the water inlet 114 of washtub pedestal 110, flow out by delivery port 120.At this moment, because water inlet 114 and hydroecium 118 conjointly are formed on the bottom surface of washtub pedestal 110,, improve the cycle efficieny of water so the water in the washtub 100 enter into hydroecium 118 naturally by water inlet 114.Entered the water of going into hydroecium 118 of washtub pedestal 110, flowed out, flowed to the delivery port 220 and the outlet 230 of balancer 210 again by the water route 144 of the 1st plate 140 respectively by delivery port 120.Specifically, rotation by palsating equipment 280, blade 284 is below put down water at palsating equipment 280 toward the side, so, after the centrifugal force of palsating equipment 280 makes the water inlet 114 of water by washtub pedestal 110 in the washtub 100 enter hydroecium 118, flow to the water route 144 of the 1st plate 140 by delivery port 120.Therefore, in the water route 144 of the 1st plate 140, produce pressure, the top that is raised to waterborne in water route 144, the delivery port 220 and the outlet 230 of balance between supply and demand device 210 respectively.
Like this, the water route 144 by washtub 100 is given to the delivery port 220 of balancer 210 and the water of outlet 230, falls from the top of washtub 100, produces so-called vertical flowing water.The flowing water that should hang down impacts the substrate that is positioned at washtub frontside edge portion, washs.At this moment, the net 248 that foreign matter (for example the end of a thread) is filtered assembly 240 in the water that comes out of the delivery port 210 by balancer 210 filters out.Because outlet 230 along the circumferential direction forms strip shape at the inner peripheral surface of balancer 210, so the water by outlet 230 comes out on the top of washtub 100, produces the flowing water that hangs down along large tracts of land, so, improve detersive efficiency.In addition,, and expand out gradually towards balancer 210 centers because that the section of outlet 230 forms is less, so, the water that comes out by outlet 230 to go out waterpower strong, can improve detersive efficiency.
Because delivery port 220 and outlet 230 are formed on the inner peripheral surface central authorities of balancer 210, so even when dropping into the substrate of volumes in the washtub 100, these delivery ports 220 and outlet 230 can not stopped up by substrate yet.In addition, distance ground produces the flowing water that hangs down because delivery port 220 and outlet 230 keep fully with substrate, so, prevent the reduction of detersive efficiency effectively.
As Figure 16, Figure 18, Figure 19 and shown in Figure 20, because the inclined plane 176 of the basal area tegmentum 170 in water route 144 forms the shape that diminishes gradually to top from the bottom, so, feed water effectively.Promptly, because the basal area in water route 144 is more up more little water flow velocity quickening, so, not only reduce the loss that pipe friction (pipe friction) brings, and prevent that in the water route 144 top weakens because of the centrifugal action of palsating equipment 280, and the phenomenon that can not feed water improves the cycle efficieny of water more.Like this, the water of volume is supplied with by water route 144, improves cycle efficieny, has more increased the generation of vertical flowing water, and simultaneously, washing agent fully dissolves, and improves detersive efficiency.In addition, even when the water levels in the washtub 100 are low, feedwater also can fully be carried out and produce vertical flowing water, so, prevent that detersive efficiency from reducing.
By the rotation of palsating equipment 280, the substrate and the circular arc protuberance 142 that are rotating in washtub 100 inside join, so keep rotation status naturally, do not damage substrate.In addition, substrate toward the top and the bottom circulation of washtub 100, can wash sleekly equably.Substrate contacts rotation on one side on one side with the embossing 150,164 of the 1st and the 2nd plate 140,160, so, more effectively substrate is washed.
Like this, during the washing stroke of washing machine, in the inside of washtub 100, flowing water rotates with the protuberance 142 of the 1st plate 140 and contacts while substrate is hung down.At this moment, the ripple rib 146 of protuberance 142 prevents that protuberance 142 is out of shape because of the impact of substrate.That is to say,, strengthened the intensity of protuberance 142, prevent the distortion of body 130, improve reliability owing to the formation of ripple rib 146.
During stroke, the protuberance 142 by rotation washtub 100 remains rotation status with whole substrates in dehydration, so, prevent from effectively the wrapping phenomena of substrate from washing to be more prone to.In this dehydration stroke, by the interruption of geared system 260, washtub 100 rotation, the contained moisture of substrate is discharged in the water storage barrel 90 by the hole 148,162 of washtub 100, dewaters.
Be that most preferred embodiment of the present invention is described above, still, in not breaking away from claim scope of the present invention, those skilled in the art can do various changes.
According to the present invention, the assembling of washtub pedestal and washtub body is more prone to, and improves the cycle efficieny of water, produces the flowing water that hangs down more, can wash substrate equably, more improves detersive efficiency and washing reliability.
