Japanese kokai publication sho 55-26908 number public clothes disclose the automatic washing machine that the present invention is had connection.Described according to this communique, in the above outside the opening in the groove, dispose same above in the washing machine that washs the drench pit of holding concurrently of opening, from above-mentioned water jacket and wash on the drench pit of holding concurrently, by face opening on these each grooves, the heart supplies water among washing the drench pit of holding concurrently.
Yet, adopt this method of supplying water, for example after the dehydration, carry out when the dehydration cleaning washing (washing), can't carry out gratifying dehydration and clean.
When the dehydration of dewatering before cleaning, washed system and be attached to the side wall inner surface of washing double drench pit.The method of being cleaned simultaneously of system's dehydration is cleaned in so-called dehydration.That is, when dehydration is cleaned, the water supply time that washs the drench pit of holding concurrently is permeated in the finite time of the degree of being washed thing totally for being water.After this time has pass, stop to supply water, wash the drench pit and dewatering of holding concurrently with rotation at a high speed.By this dehydration, cleaning agent is dispersed with water and clean it.And when this dehydration was cleaned, output got final product for water is permeated in the degree of being washed thing, can control the water yield used thus and economize on water scheming.
Therefore, though water system only is applied to water is permeated totally in the finite time of the degree of being washed clothes, but because of the major part of this water is to flow down to washing the drench pit center of holding concurrently, therefore, seldom flow to be adjacent to and washing the side wall inner surface of drench pit of holding concurrently, when carrying out down afterwards dehydration, can't cleaning agent be dispersed with water with this state.Therefore, can't accomplish sufficient cleaning and dewatering.
Again, as above-mentioned method of supplying water in, for example wash and after dewatering, the water storage that keeps the quantitative water of institute and stop to carry out under the state of water supply in washing the drench pit of holding concurrently cleans, and keep continuing to supply water after the water of ormal weight and water is overflowed and the water filling carried out when cleaning, still have and clean not enough and situation that can't fully clean.
That is, wash the water that the drench pit of holding concurrently contains ormal weight, washed thing and be immersed in entirely and also can't eliminate the state that is attached to the side wall inner surface of washing the drench pit of holding concurrently by washing clothes in the water.Therefore, though revolution wing revolution was arranged when the stage of cleaning, during initial in clothes not too move and cause cleaning deficiency, can't fully clean.
Therefore, one of purpose of the present invention is to carry out fully in washing machine and cleans.
Another object of the present invention is to carry out sufficient cleaning and dewatering in washing machine.
The present invention's another purpose is to carry out sufficient cleaning person with simple structure in the washing machine of carrying out cleaning and dewatering.
The present invention's above-mentioned purpose realizes by making washing machine comprise following important document.
That is, have groove outside the peristome above washing machine comprises, and be located in the water jacket, top have peristome drum wash double drench pit.But this washs the drench pit system of holding concurrently is axis and high speed rotary with the circle center that constitutes cylinder.From water jacket and wash the drench pit of holding concurrently and supply water.
The water supply export department of water supply pipe is provided with the water supply direction change device with water face side flow within the cylinder wall that washs the drench pit of holding concurrently of supply.
Water from water supply pipe washs the side wall inner surface of drench pit of holding concurrently for being flowed to by the water supply direction change device.Therefore, be attached to and wash the side wall inner surface of drench pit of holding concurrently, still can be washed thing water-sprinkling well quilt even if wash thing during the dehydration after washing etc.
Therefore, during waters supply when dehydration is cleaned, water can permeate well and be washed thing, can carry out the dehydration cleaning satisfactorily.And, washed thing by water-sprinkling and moisture quilt and be easy to fall down, or in fact can fall down to washing within the drench pit of holding concurrently side.So touching also has water to sprinkle in partly the exposing of side wall inner surface of washing the drench pit of holding concurrently to this part to arrive, water more permeates in being washed in the thing, can carry out dehydration more satisfactorily and cleaning.
Again, clean and water filling when cleaning at water storage, make similarly during water supply washed thing be easy to wash within the drench pit of holding concurrently that side is fallen down or in fact example can eliminate the major part that touch situation of being washed thing down.Therefore, in fact when the stage that will clean, the mobile status of being washed thing can be carried out water storage cleaning or water filling cleaning etc. satisfactorily for good at the very start.
The present invention's purpose, function and effect will be clear when can more attaining from following detailed description and accompanying drawing.
Now with reference to figure 1, just the present invention's automatic washing machine is described as follows.Washing machine is, in machine frame 1, be provided with by 4 hang support that excellent (not shown) suspends in midair, groove 2 outside the opening above it.In water jacket 2, be provided with have a plurality of dewatering holes 4 around it, same opening washs the drench pit 3 of holding concurrently above it.This washs the drench pit 3 of holding concurrently is to be that the center is turned round with the rotating shaft 5 that is located at diapire.In above-mentioned bottom of washing in the drench pit 3 of holding concurrently, rotation sets the revolution wing 6 freely.CD-ROM drive motor 7 passes on mechanism 8 to be linked to above-mentioned washing on the drench pit 3 of holding concurrently by power.This CD-ROM drive motor 7 is when washing and cleaning usually (water storage cleans and water filling is cleaned), only make the revolution wing 6 low speed rotation, being about to wash the drench pit 3 of holding concurrently when being washed thing dehydration (dehydration when comprising cleaning and dewatering) is the center with rotating shaft 5, rotates (this time the above-mentioned revolution wing 6 also rotation at a high speed simultaneously) at a high speed to single direction.For supplying water to washing the drench pit 3 of holding concurrently by face opening on these each grooves from above-mentioned water jacket 2 and on washing the drench pit 3 of holding concurrently, be provided with water supply pipe 9, the way is provided with electromagnetism feed water valve 10 among this water supply pipe 9.The diapire of water jacket 2 is provided with drainpipe 11.The way is provided with electromagnetism draining valve 12 among the drainpipe 11.The air collector of water jacket 2 bottoms (air trap) 14 has water level sensor 13 mat pressure hoses 15 and connects.Predict with this water level sensor 13 and to wash interior the water level of the drench pit 3 of holding concurrently, be supplied in as can be known and wash the interior water yield of double drench pit 3.The details of water level sensor 13 is for for example being disclosed in the special fair 2-44557 communique.
Water supply pipe 9 is provided with water outlet.This water outlet 16 has the water flowing road 18 of a plurality of apertures 17 for as shown in Figure 2 by lower wall, and the recess 19 that is positioned at these 18 belows, water flowing road becomes.Fig. 3 in detail detergent container 20 of demonstration is to be installed in the recess 19 of above-mentioned water outlet 16 to become the state that can freely put into and take out from the place ahead.When washing, cleaning agent is devoted in this detergent container 20 in advance.The wall bottom is provided with opening 21 after this detergent container 20.When recess 19 was installed this detergent container 20, gapped 22 existed between this detergent container 20 and recess 19.This gap 22 is a mat rear wall openings 21 and passing in this detergent container 20.When being desire input cleaning agent, uses handle 23 for pulling out above-mentioned this detergent container 20.This handle 23 is integrally formed with this detergent container 20.Water outlet direction change body 24 side after handle 23 is integrally formed with this detergent container 20.When this detergent container 20 was installed, this water outlet direction change body 24 was, was along with descending near the tilted shape of washing the double sidewall that takes off inside groove 3 simultaneously, as shown in Figure 4, was and slightly concentric circular-arc of the above-mentioned sidewall that washs the drench pit 3 of holding concurrently.
When washing, in advance cleaning agent is devoted detergent container 20, and this detergent container 20 is installed under the state of above-mentioned recess 19, when opening feed water valve 10, come water outlet 16 by the running water of water supply pipe 9.Then, running water for from water flowing road 18 in a plurality of apertures 17 fall within above-mentioned detergent container 20, flow into above-mentioned gap 22 with the cleaning agents in the detergent container 20 by rear wall openings 21.Afterwards, the running water that contains cleaning agent promptly washs water side before the gap 22 to flow to water outlet 16 outside and be supplied to above-mentioned washing in the drench pit 3 of holding concurrently.
During cleaning (water storage cleans, and water filling is cleaned, and dehydration is cleaned), detergent container 20 is installed on recess 19 under the state with the whole outflows of cleaning agent when washing.Then, during open feed water valve 10, running water promptly as above-mentionedly flow to water outlet 16 and fall within the detergent container 20 by aperture 17 from water flowing road 18.Yet, there has not been cleaning agent in the detergent container 20, therefore, running water flow to gap 22 by rear wall openings 21, flows out water outlet 16 outsides and is supplied in and washs the drench pit 3 of holding concurrently.
Water outlet direction change body 24 is to be to tilt and circular shape.Therefore, flow out and be supplied in the water that washs the drench pit 3 of holding concurrently from the water outlet 16 of water supply pipe 9, effect because of water outlet direction change body 24, from water outlet 16, as among Fig. 4 with shown in the part W shown in a plurality of points, be the state that circular-arc some expansions are opened, fall to the side wall inner surface (just as being pushed back) of washing the drench pit 3 of holding concurrently.Solid line A among Fig. 1 is the approach that falls of the water when showing this.
Fig. 5 shows the square circuit of washing machine.Washing machine comprises the control part that micro computer constituted 25 by the control washing machine.This control part 25 is to predict drive controlling CD-ROM drive motor, electromagnetism feed water valve 10 and electromagnetism draining valves 12 such as result according to the key input signal of key input part 26 and above-mentioned water level sensor 13.
Fig. 6 is the precedence diagram of the basic sequence of operation of demonstration washing machine.With reference to Fig. 6, control part is at first carried out the process of washing, and then carries out dehydration cleaning process and common cleaning process (water storage cleaning) successively, carries out dehydration at last.
Fig. 7 system is stored in the flow chart of the formula of above-mentioned control part 25.Now as follows according to this figure to the action specification of washing machine.At key input part 26 operation initiate keies, when the initiate key signal arrived control part 25, the process of washing was at first carried out in control part 25 entrys into service.Wash in the process at this, control part 25 is opened feed water valves 10 and is carried out water supply (step S1) till above-mentioned water level sensor 13 predicts predetermined water level (until washing till the water of storage ormal weights in the double drench pit 3).This time, when washing, detergent container 20 is had the cleaning agent of input in advance, therefore, supply with and wash water washing the drench pit 3 of holding concurrently in the above described manner.Then, when predicting predetermined water level, close feed water valve.Then, when storing the water of ormal weight, control part 25 drives above-mentioned CD-ROM drive motor 7 and only makes the revolution of the revolution wing 6 low speed, and carries out the process (step S2) of washing.
After the above-mentioned process of washing ended, control part 25 was then to carry out the dehydration cleaning process.In the dehydration cleaning process, open row water valve 12 and discharge the water that washs when washing at first washs with rotation at a high speed and to hold concurrently drench pit 3 and the revolution wing and carry out from being washed thing dehydration (step S3).Finish after this step, carry out dehydration and clean (step S4).Draining valve 12 is kept open state.
With reference to Fig. 8, at the appointed time when the t in, open feed water valves 10 of control part 25 and supplying water.In when this common water, control part 25 repeats to carry out 5 seconds action of the driving 1 second of above-mentioned CD-ROM drive motor 7-stop.This time, wash the drench pit 3 of holding concurrently and repeat to carry out and play desire with revolution wing 6-and begin the action that enters the inertia turn state immediately after the high speed rotary state.Its result washs the drench pit 3 of holding concurrently and turns round (10~100rpm) lentamente.
Therefore, washing carrying out simultaneously of the drench pit 3 slow revolutions of holding concurrently supplies water.At this moment, because dehydration at the step S3 that washs the back, be attached to the side wall inner surface of washing double drench pit 3 though wash thing C, but water is by the effect of water outlet direction change body 24, promptly according to the inclination of water outlet direction change body 24 and circular-arc, expand a little as described above and be split into to circular-arc to the side wall inner surface stream that washs the drench pit 3 of holding concurrently.Therefore, water spilling well infiltration well to being washed thing C.Crossed after the above-mentioned time t, become the state that water fully permeates.
Afterwards, close feed water valve 10, control part 25 driving CD-ROM drive motor 7 certain hours (for example 5 minutes) make and wash the drench pit 3 of holding concurrently to rotate (more than the 900rpm) at a high speed and to dewater.Thus, cleaning agent disperses with the water of abundant infiltration.
If the drench pit 3 and feeding water of holding concurrently is washed in revolution lentamente that will be above-mentioned, a succession of and his like journey of dehydration is made as a circulation then, and practicable two circulate in the dehydration cleaning of step S4.This time, during the supplying water of the 2nd circulation, washed the side wall inner surface of drench pit 3 of holding concurrently because the dehydration of the 1st circulation is attached to though wash thing C, water still spilling is well washed thing and is permeated well to quilt.
During waters supply in each circulation of dehydration cleanings, water permeates well and is washed thing, can carry out the cleaning of dewatering satisfactorily.And, have the water spilling to and have moisture quilt to wash thing C to be easy to fall down, perhaps in fact to fall down to washing within the drench pit 3 of holding concurrently side.So, being washed being attached to of thing C and wash the part of the side wall inner surface of the drench pit 3 of holding concurrently and promptly expose and this part is also had the direct spilling of water, water permeates more well in being washed in the thing, can carry out the dehydration cleaning more satisfactorily.
Moreover, above-mentioned water outlet direction change body 24 for slightly concentric circular-arc of the sidewall that washs the drench pit 3 of holding concurrently, therefore, water becomes circular-arc, along the circle shape side wall inner surface of washing double drench pit 3, thereby water spilling is more well washed thing C to the quilt that is attached to the side wall inner surface of washing the drench pit 3 of holding concurrently, make moisture quilt wash thing C and promptly be easy to fall down, perhaps in fact fall down to washing within the drench pit 3 of holding concurrently side.
Moreover, during water supply when dehydration is cleaned, wash the drench pit 3 of holding concurrently and carry out the low speed revolution, therefore, though institute is washed thing C and is attached to full week (normally becoming so) of the side wall inner surface of washing the drench pit 3 of holding concurrently, water can spilling wash thing and same situation takes place to whole quilts, carries out dehydration more satisfactorily and cleans.
Finish after the above-mentioned cleaning and dewatering process, control part 25 is then carried out and is cleaned (water storage cleaning) usually.In this process, as the process of washing, control part 25 is opened feed water valves 10 and is supplied with running water (step S5), until above-mentioned water level sensor predicts till the predetermined water level.Before common cleaning process, close draining valve 12 in advance.When predicting predetermined water level, close feed water valve 10.Then, when storing the water of ormal weight, control part 25 only makes 6 revolutions of the revolution wing under the driving of carrying out above-mentioned CD-ROM drive motor 7, use and carry out water storage cleaning (step S6).
When this water storage cleans, also when supplying water, there is water spilling well to permeate equally to substrate.Then, the water spilling is arranged and moisture substrate is easy to fall down to washing within the drench pit 3 of holding concurrently side, perhaps in fact fall down,, can greatly eliminate this person of touching though washed thing and be attached to and wash the side wall inner surface of drench pit 3 of holding concurrently owing to the dehydration of the 2nd circulation of the dehydration cleaning in step S4 makes.Therefore, when the stage of the water storage cleaning of reality, it is good to be washed moving of thing from the outset, cleans and can carry out water storage satisfactorily.
Moreover, water outlet direction change body 24 for slightly concentric circular-arc of the sidewall that washs the drench pit 3 of holding concurrently, therefore, water becomes circular-arc, flow along the circle shape side wall inner surface of washing the drench pit 3 of holding concurrently, thereby water spilling is more well washed thing to being attached to the quilt that washs drench pit 3 side wall inner surface of holding concurrently, and more can eliminate the phenomenon that touch of being washed thing.
Moreover, during water supply when water storage cleans, the same when turn round when washing the drench pit 3 of holding concurrently and cleaning with low speed with dehydration, washed thing and can be touched entirely all (normally like this) in the side wall inner surface of washing the drench pit 3 of holding concurrently, but to being washed thing the bold and vigorous water that arrives is arranged all, washed touching of thing and more can eliminate.
Above-mentioned common cleaning process at the end, the last dehydrations of carrying out of control part 25.In dehydration, open row water valve 12 and discharge the water (step S7) of water storage when cleaning at first.Draining at the end, control part 25 makes and washs the drench pit 3 of holding concurrently with high speed rotary, carries out dehydration (step S8).Draining valve 12 is kept open state.After dehydration ends, running is ended.
In the above-described embodiments, in common cleaning process, carry out water storage and clean, also can but clean the cleaning of replacement water storage with water filling.
More than describe one of the present invention embodiment in detail, but this embodiment and non-limiting the present invention, the present invention system is limited it with the scope of following claims.
