Fig. 7 is the top view of observing the recirculated water cover 30 of the state that wired bits filter 38 is installed from the top, Fig. 8 is the outside drawing that having opened of line bits filter 38 covered 53 state, Fig. 9 has pulled down from line bits filter 38 to cover 53 and the top view that represents, Figure 10 is the cutaway view of the line bits filter 38 cut open of the chain-dotted line A-A with Fig. 4, and Figure 11 is the cutaway view of the inflow entrance of the line bits filter 38 cut open of the chain-dotted line B-B with Fig. 4.
The groove 38b, the 38c that possess locking usefulness in the left and right side of handle 38a.Substrate 54 is box-shaped bodies of anterior and upper opening, and handle 38a can be installed on the axle of the central authorities that are located at rear side 54d rotatably.Consider line to be worth doing filter 38 and insert installing port 30c, make handle 38 rotations and the stop pin 30b of support portion 30a that will be located at the both sides of installing port 30c puts into groove 38b, 38c, thus locking handle 38a.At this moment, be located at the protuberance of rear side 54d and be close to the packing ring 56 on every side of being located at installing port 30c, thereby anti-sealing spills from recirculated water cover 30. Side 54a, 54b about substrate 54 possess dead eye 54c, install for the axle of lid 53 described later.
There is spin chamber 51 in front end at substrate 54.Part at the peripheral wall surfaces 51f of spin chamber 51 is provided with otch, and otch is connected with the entry section 55 that is connected with sidewall 51c by sidewall 51b.Sidewall 51b connects in the roughly tangential direction of the peripheral side wall of spin chamber 51.And, sidewall 51b and sidewall 51c are set as along with towards spin chamber 51 and the interval narrows down, the flow path area that makes entry section 55 gradually dwindles and increases the flow velocity of the water that flows towards spin chamber 51, and making flows relies on the profile side of spin chamber 51, thereby stably produces rotary current in spin chamber 51.In addition, have the many places peristome that is surrounded by frame 51e at peripheral wall surfaces 51f, at the inner peripheral surface of peripheral wall surfaces 51f, be close to without jump ground and be provided with reticular filter 51a.
At the base plate 52 of spin chamber, have the many places peristome that is surrounded by frame 52b, at the upper surface of base plate 52, be close to without jump ground and be provided with reticular filter 52a.Lid 53 has the many places peristome, at the lower surface of lid 53, is close to without jump ground and is provided with reticular filter 53a.In the outside of reticular filter 53a circular packing ring 53b is installed, if closing cap, then the upper end of the peripheral wall surfaces 51f of packing ring 53b and spin chamber 51 is close to.Put into dead eye 54c by the axle 53c that will be located at the rear end and come mounting cover 53, and can centered by axle, open and close handle 38a side.Like this, reticular filter is close to installed surface without jump ground, thereby does not have the situation of hooking the line bits in the end of reticular filter.
At lid 53 upper surface, be provided with abreast groove 53d with the installation direction of line bits filter 38, by hookup wire bits filter 38, the rib 31d of lower surface that will be formed at the rear surface 31b of water jacket cover 31 is inlaid in groove 53d.On the other hand, be formed with outstanding to the inside protrusion 30d in the bottom surface of recirculated water cover 30.This is in order between base plate 52 and recirculated water cover 30 slit to be set, and the washings that flow out from the reticular filter 52a of base plate are flowed in this slit.If hookup wire bits filter 38, then line bits filter is by rib 31d and protrusion 30d clamping, pressing cover 53.Therefore, can prevent pressure because of the washings that flow into spin chamber 51 make cover 53 open, washings are directly considered filter to be worth doing by line situation.
In addition, flow into reliably entry section 55 in order to make washings, be provided with rectification part 31c at the lower surface of the rear surface of water jacket cover 31 31b, be provided with rectifying component 37b at recirculated water cover 30.Lower surface at rectification part 31c possesses packing ring 59.In addition, be provided with packing ring 60 at the inner surface near the recirculated water cover 30 of the downside of the entry section 55 of base plate 52.If at recirculated water cover hookup wire bits filter 38, the then upper surface of the end face of the lower surface of rectification part 31c and sidewall 51c, rectifying component 37b and the upper surface butt that covers 53, the end face butt of the end face of sidewall 51b and rectifying component 37b.Thus, can the entry section 55 that roughly all guides to line bits filter 38 of washings of the circulation waterway 37c of recirculated water covers 30 will be flowed into from recirculated water entrance 33.In addition, make the jump of part of butt minimum, and can not produce mobile resistance or hook the line bits.
If circulating pump 16 runnings, then the washings in the water jacket 10 flow to the top of water jacket 10 by circulation pipe 17 from the water-through and ventilating mouth 10b that is located at outer slot bottom, enter the circulation waterway 37a of recirculated water cover 30 from the recirculated water entrance 33 of water jacket cover 31, utilize line bits filter 38 to remove the line bits, and washings flow in the washing and dewatering groove 9 (with reference to the arrow of Fig. 5, Fig. 7) from Water spray nozzle 34 by circulation waterway 37.
The mobile of washings in the recirculated water cover 30 is elaborated.Washings enter the 55(of the entry section arrow 61 of line bits filter 38 from circulation waterway 37a).The flow path area of entry section 55 becomes the shape of dwindling, thereby the flow velocity of washings enters in the spin chamber 51 with increasing, becomes the rotary current (arrow 62) along peripheral wall surfaces 51f.Because the line that contains in washings bits are lighter than water, thereby Yi Bian the line bits because rotary current and basically be accumulated into cylindric in the substantial middle section revolution of spin chamber 51 on one side.Washings flow out ( arrow 62a, 63,64) from reticular filter 51a, 52a, the 53a that is located at line bits filter 38 to circulation waterway 37.At this moment, residual line bits are removed, and remain on the reticular filter surface.In general line bits filter, the flow direction of washings is substantially vertical with filtering surface, and at filtering surface attached wire bits, the effect of the line bits burden filter that accumulates, thus the line bits accumulated always.Therefore, increase the pressure loss of stream, and reduce the circular flow of washings.But in the present embodiment, washings flow pivotally along reticular filter, thereby the attachment state to the reticular filter surface of line bits dies down.Therefore, if the line of mesh filter house bits increase, then the fluid force by washings can divest simply, and the effect that utilizes convolution to flow concentrates on the central portion of spin chamber 51.Like this, reticular filter automatically cleans, thereby can wired bits lodge in reticular filter and the situation of blocking reticular filter, can roughly remain the circular flow of washings constant.In addition and since do not need with the reticular filter area become greatly need above, thereby the miniaturization aspect of considering online filter 38 to be worth doing is also effective.For the line bits that as above gather, if the washing water circuit stops, then the substantial middle section at base plate 52 becomes the dumpling shape.Therefore, when removing line bits filter, pull down line bits filter 38, open and cover 53 and consider line to be worth doing filter 38 and be inverted (making base plate 52 become upside), knock gently, then line is considered to be worth doing and can be fallen simply.Therefore, without the direct contact wire bits of hand, and can carry out simply the removing of line bits filter 38.In addition because general plane shape and the planar shape of cylinder of reticular filter, some dotted line bits that are attached to reticular filter also can enough brushes etc. gently brush and easily removing.
In the present embodiment, near the peripheral wall surfaces 51d the spin chamber entrance, base plate 52c, lid 53e do not arrange peristome.This is as rear explanation, owing to make small-sized, the flattening of line bits filter, so the length of entry section 55 can be very not long, thereby the washings that enter the spin chamber 51 of line bits filter can not flow out from reticular filter immediately, and then can be efficiently and reliably at spin chamber 51 interior generation rotary currents.
In addition, in the structure of present embodiment, as shown in figure 11, be provided with line bits filter 38 in the position than the low one deck of circulation waterway 37c.This is for the line bits filter 38 from the recirculated water entrance 33 of the upper surface that is positioned at water jacket cover 31 to the lower surface of being located at water jacket cover 31 or Water spray nozzle 34 washings that flow.Therefore, because the washings that enter entry section 55 have the speed towards the below, thereby near the base plate 52c the inflow section of spin chamber 51 does not arrange peristome.This is owing to following reason, if namely water has larger flows at angles for reticular filter, then be difficult to utilize fluid force to remove the line bits, thereby reticular filter stops up easily.Therefore, near the bottom parts 52c inflow section does not arrange opening, in this part the mobile of water is done one's utmost along the face of reticular filter 52a.In addition, the structure aspect in the situation that the washings in entering spin chamber flow into respect to the angled mode of cylindrical direction tool with flow direction, for flow carries out rectification, arranges wall near the entrance of spin chamber.That is, peristome (mesh filter house 51a) is not set.If certainly size has enough and to spare, then owing to fully guarantee the length of entry section 55, thereby do not need to carry out above-mentioned countermeasure.
In line described above bits filter 38, suppress the height of recirculated water cover 30 in the mode of the motion that do not hinder the clothing in washing or the washing and dewatering groove 9 when dry, thereby realize small-sized, the flattening of line bits filter 38.Therefore, in order to ensure the flow of washings, peripheral wall surfaces 51d, base plate 52,53 3 faces of lid of considering online filter to be worth doing arrange peristome (reticular filter), increase filter area.
But the size of considering online filter to be worth doing has in the situation of enough and to spare, need to reticular filter be set at whole three faces.In this case, at sidewall peristome is set, the little peristome that is provided for draining at base plate 52 is relatively good.This is owing to following reason, namely, be attached to that the line bits of reticular filter of sidewall are the easiest to be removed by the fluid force of rotary current.And, with bonding, welding etc. the position of reticular filter is set owing to reduce, thereby can cuts down finished cost.
In addition, base plate 52 forms the low stamp box shape of central part, and the peristome (reticular filter) that is provided for draining in its bottom is better.After the washing water circuit stops, can carry out draining from the line bits that capture efficiently, thereby can remove more like a cork.
The washings of circulation waterway 37 enter in the Water spray nozzle 34 (arrow 65) from entrance 34b.And, flow in the Water spray nozzle 34 along the peripheral wall surfaces of spin chamber 34a, and again become rotary current (arrow 66).And, from the outlet 34c of bottom surface to the 9 interior discharges of washing and dewatering groove.Because to the rotating centrifugal force of water effect in the spin chamber 34a, thereby become the cone shape film-form of expansion downwards while the water of discharging from outlet 34c turn round shown in the arrow 67 of Fig. 2, and roughly equably washings is sprayed.Therefore the water yield, make washings spread all over washings, even also can realize high clean power less.
If the running of circulating pump 16 stops, then certainly washing water circuit and stop, but be full of washings in the circulation pipe 17, recirculated water cover 30, these washings because of gravity at a heat by circulation pipe 17 to water jacket 10 interior adverse currents.Therefore, if circulating pump 16 cuts, then the line bits that capture of line bits filter 38 are also in washings return the circulating pump 16 of water jacket below or in the circulation pipe 17 inside and outside grooves 10.This is a kind of back washing effect, does not need to remove the line bits in the line bits filter.But, become piece in the online bits of the line bits filter, thereby the worry of stopping up the draining catcher when stopping up circulation pipe, draining scupper hose 24 interior flowing arranged.
Therefore, in the situation that circulating pump 16 stops, the rotating speed of circulating pump descends, and it is identical or kept 5～10 seconds than the rotating speed of low height to become height with the lower surface of line bits filter 38 with the discharge water potential difference height of circulating pump, stops afterwards.Like this, on one side make washings adverse current slowly in the recirculated water cover 30 on one side from Water spray nozzle outlet 34c air amount, thereby can prevent lines bits in the principal vertical line bits filter 38 with washings to circulation waterway 37c side flow.
Figure 12 is the block diagram of the control part of scrubbing-and-drying unit.Symbol 40 is microcomputers, it is connected with the operation push-button input circuit 41 that is connected in each switch 6,6a, level sensor 21, temperature sensor 26, vibrating sensor 27, and accepts the various information signals in user's button operation or washing procedure, the drying process.From the output of microcomputer 40 switching of the water supply electromagnetic valve 4 that is connected with drive circuit 42, clutch 12, draining valve 15, circulation pipe 16, washing dehydration drive motor 13, Air Blast fan 19, heater 20 etc. or rotation, energising are controlled.In addition, seven sections light emitting diode indicators 25, light emitting diode 7, the buzzer 43 with the operating state that is used for notifying user's washing machine is connected.
If pushing power switch 5, plugged, Figure 13 and washing and dry basic control handling procedure shown in Figure 14 are carried out in then above-mentioned microcomputer 40 startings.
Step S101
Carry out state confirmation and the initial setting of scrubbing-and-drying unit.
Step S102

Step S103
The indication input that the beginning switch 6a of the operation push-button switch 6 of guidance panel 8 is sent monitors and branch is carried out in processing.
Step S104
Carry out the detergent amount Check processing.This detergent amount detects and carries out in the following way, namely, under the drying regime before supplying with washings, so that washing and dewatering groove 9 static states make impeller dish 11 single direction rotations, at this moment, based on the rotary load amount that acts on this impeller dish 11, mode with the laundry amounts that detects washings is controlled washing dehydration drive motor 13 and the Electromagnetically-operating clutch 12 of washing dehydration drive unit, obtains the dosage (detergent amount) of washing agent based on the laundry amounts that detects.Detergent amount is obtained by the laundry amounts of reference preliminary election setting and the table of comparisons of detergent amount.Particularly, the detection of laundry amounts is being used in the structure of frequency conversion drive motor as washing dehydration drive motor 13, by the arrival rotary speed after the stipulated time so that the mode of washing dehydration drive motor 13 rotations is powered is detected to carry out.And using in the structure of electric capacity phase-splitting monocyclic-start induction motor as washing dehydration drive motor 13, detect to carry out by the inertia rotation deceleration characteristic after the state that makes washing dehydration drive motor 13 rise to saturated rotary speed with power supply is cut off the power supply.And preferred washing agent is by obtaining with reference to the table of comparisons of predefined laundry amounts and washing agent.
The washing water yield is set to the washing water yield (water level h1), so that when laundry amounts is in the scope (in right amount) of the laundry amounts of regulation, keep the water level of not crossing impeller dish 11 and the bottom that accumulates in water jacket 10.
And, obtain wash time and set based on this testing result (laundry amounts).When not carrying out the detection of laundry amounts, the wash time of established standards.
Step S105
Step S106
Open the washing agent water supply electromagnetic valve, carry out to the washing agent of washing/soft finish agent container 28 and drop into the water supply of chamber supply washing agent.The user drops into washing/soft finish agent container 28 with the powder detergent of shown amount, and enclosing cover 3 is closed in afterwards operation.Bottom to water jacket 6 falls the water that the powder detergent that drops into for the washing agent input chamber of water flow to washing agent supplies water with washing agent by washing/soft finishing agent entrance 28.
Step S107
Supply water and to the detergent dissolution water level, stop to supply water.In this embodiment, irrelevant with detergent amount (laundry amounts), the washing agent output is set as about 10 liters.This water yield be when after detergent dissolution operation (step S108) in when making washing and dewatering groove 9 rotation for stirring the water supplied with and the water yield of washing agent abundance in the bottom of washing and dewatering groove 9, and the water surface is set as the height low (washings is nonwetting before detergent dissolution) than the lower surface of impeller dish 11.
Step S108
By making integratedly unidirectional slow rotation of washing and dewatering groove 9 and impeller dish 11 (about per minute 70 turns), carry out detergent dissolution, namely, in the bottom surface of this washing and dewatering groove 9 the detergent dissolution water of the bottom that devotes water jacket 10 and powder detergent stirred and generate the washings of high detergent concentration.If the time of detergent dissolution be 1 minute then enough.It also is about 90% dissolution rate under the condition of low temperature (low water temperature), the powder detergent that is difficult to dissolve.The detergent concentration of the washings that generate is about 7 times.Herein, normal concentration is the ratio of 30 liters of the powder detergent amount 20g/ washing water yields.
Step S109
Washing before carrying out.Should before washing make the stirring that makes off and on impeller dish 11 positive and negative rotations under the static state of washing and dewatering groove 9, and in the positive and negative rotation process of impeller dish 11 by making circulating pump 16 runnings come to spray from Water spray nozzle 34 to washings the washings of the bottom of water jacket 10.At the stopping period of impeller dish 11 and circulating pump 16, with reference to the detection signal of level sensor 21 on one side open washing agent water supply electromagnetic valve and washing water supply electromagnetic valve and in the mode that do not make water level surpass designated water level replenish to supply water on one side.By repeatedly repeatedly should running, make washings fully impregnated in washings and disperse at impeller dish 11.
When primary positive and negative rotation, the about 7 times washings of detergent concentration are sprayed on washings and soak in this washings.The washings of high concentration spray to whole washings from the outlet 34c of Water spray nozzle 34, thereby because the penetrant action of washing agent soaks into washings equably.The solvability of oil of washings of high concentration of soaking into washings is high, and dissolving grease dirt, and make dirt very large from the effect that washings floats, thus high clean power obtained.

Bottom inside at washing and dewatering groove 9 can be provided with impeller dish 111 with rotating freely.The surface configuration of impeller dish forms the shape identical with impeller dish shown in Figure 3 11, perhaps also can form the general agitator arm that is provided with a plurality of male rib of extending radially from the center on disk.Possesses radial a plurality of interior impeller 111a at the back side of impeller dish 111 (lower surface).The bottom of washing and dewatering groove 9 around impeller dish 111, be provided be used to dwindle impeller dish 111 around and the bottom annulus 9c of the ring-type in slit between the inner peripheral surface of washing and dewatering groove 9.Peripheral part and bottom annulus 9c by impeller dish 111 form labyrinth type sealing ring, thereby are difficult to make the slit of washings between impeller dish 111 and bottom annulus 9c to be flowed.Bottom annulus 9c has the barrel surface 9d that roughly is close in the bottom surface of interior perimembranous and washing and dewatering groove 9.Annulus 9c is formed with the many places notch in the bottom, and circulation waterway cover 71, the circulation waterway cover 81 of washings is set at this notch.Section shape is roughly C word shape and backside openings if circulation waterway cover 71,81 is cut open then at horizontal plane, but is set to be close to the periphery wall of washing and dewatering groove 9 by the back side, forms sidepiece circulation waterway 71b, 81b.In the lower end of sidepiece circulation waterway 71b, 81b, be provided with opposed to each other water inlet 71a, 81a with the outer circumferential side of interior impeller 111a.
Be formed with outlet 71c on the top of circulation waterway cover 71, at outlet 71c hookup wire bits filter 72 removably.The top of outlet 71c is close to by the inner peripheral surface of the back side and washing and dewatering groove 9 and the cylindric wall 71g of central shaft approximate horizontal closes.In addition, about outlet 71c, be formed with the supporting walls 71d for hookup wire bits filter 72, be provided with the groove 71e of the location usefulness of line bits filter 72 at the medial surface of supporting walls 71d.
Line bits filter 72 is made of the spin chamber 72a of the roughly semicircle tubular of central shaft approximate horizontal, the side plate 74 of cutting out face about it, handle 76.Be formed with the track 74a of convex at the lateral surface of side plate 74, by gripping handle 76 with track 74a insertion groove 71e, consider line to be worth doing filter 72 and be installed on circulation waterway cover 71.The rear side of spin chamber 72a has opening 75, and the front side has the roughly perisporium 73 of semicircle tubular.If line bits filter 72 is installed on circulation waterway cover 71, then the inner peripheral surface top of the perisporium 73 cylindric wall 71g of being connected with the circulation waterway cover connects without jump ground, form stream cylindraceous, thereby the washings from sidepiece circulation waterway 71b change flow direction because of cylindric wall 71g, thereby become stable rotary current in spin chamber 72a.Perisporium 73 has the peristome that many places are surrounded by frame 73b, is provided with closely reticular filter 73a at the inner peripheral surface of perisporium 73 without jump.In addition, the bearing surface of considering online filter 72 and circulation waterway cover 71 to be worth doing is provided with packing ring 77, the washings from sidepiece circulation waterway 71b substantially all can be guided in the line bits filter 72.
The upper end of circulation waterway cover 81 is closed, and is formed with the outlet 81c in the slit-shaped of general horizontal direction upper shed on the top of circulation waterway cover 81.
If impeller dish 111 rotations, then interior impeller 111a becomes centrifugal pump, near the bottom surface central authorities of impeller dish 111 pressure decreased, thus suck interior washings (arrow 92) in slit 91 between water jacket 10 and the washing and dewatering groove 9 from the through hole 9b of the bottom surface of being located at washing and dewatering groove 9.And the washings that push laterally because of the centrifugal force of interior impeller 111a flow into from water inlet 71a, 81a to sidepiece circulation waterway 71b, 81b, and in sidepiece circulation waterway 71b, 81b towards above flow (arrow 93,96).
The washings that rise in sidepiece circulation waterway 71b flow into spin chamber 72a swimmingly along the cylindric wall 71g of upper end, and become the rotary current (arrow 94) along perisporium 73 and rotating shaft approximate horizontal.Line in washings bits since rotary current and most of on one side in spin chamber 72a revolution gradually gather on one side, but because the impact of gravity, be accumulated into the cylindric of horizontal length at the downside of the central authorities of spin chamber 72a.Washings are by reticular filter 73a, and residual line bits are removed by reticular filter 73a, flow in the washing and dewatering groove 9 (arrow 95).If the line bits that accumulate at reticular filter 73a slowly increase, then utilize the fluid force of rotary current to divest the line bits, can prevent the obstruction of principal vertical line bits filter 73a, this is identical with embodiment example 1.
On the other hand, near the shower shape ground sprinkling central authorities of the washings that in sidepiece circulation waterway 81b, rise in from the outlet 81c of slit-shaped to washing and dewatering groove 9.Thus, can spray washings to washings equably, thereby can improve clean efficient.
Washings in the washing and dewatering groove 9 flow out to the slit between water jacket 10 and the washing and dewatering groove 9 by through hole 9a.
In washing process, good and reduce the winding of washings for the motion that makes the washings in the washing and dewatering groove 9, general impeller dish 111 repeatedly forward, stop, reversing, stop, thereby the washings intermittent flow from line bits filter 72, outlet 81c to the 9 interior outflows of washing and dewatering groove.If washings stop, the line bits that then capture fall to the bottom of perisporium 73.If washings flow out, then the line bits roll at the inner peripheral surface of perisporium 73, and soon because the rotary current of washings begins rotation, but gradually be involved in the line that is attached to reticular filter 73a and consider to be worth doing this moment.Therefore, the washings intermittent flow had further to suppress the effect of the increase of the line bits that are attached to reticular filter 73a.
If the rotation of impeller dish 111 stops, then the washings in sidepiece circulation waterway 71b, the 81b flow downwards.At this moment, do not flow out and the mode of carrying out easily the removing of line bits becomes following structure to sidepiece circulation waterway 71b with the line of online bits filter 72 interior captures bits.Set the up and down size of outlet 71c, so that when line bits filter was installed on circulation waterway cover 71, the wall 71h that is recycled at least water route cover 71 about half of the downside of the opening 75 of spin chamber 72a closed.As mentioned above, line bits gather at the downside of the central authorities of spin chamber 72a, thus downside half part by closing in advance opening 75, when mobile the stopping of washings, can prevent the principal vertical line bits by outlet 71c to sidepiece circulation waterway 71b adverse current.
If removing line bits, pull down line bits filter 72 from circulation waterway cover 71, then opening 75 is opened more greatly, thereby when opening 75 is knocked gently for downside, line is considered to be worth doing come off easily, thereby can carry out simply the removing of filter.
In addition, in present embodiment example 2, the outlet of a line bits filter and shower shape and setting position have been represented respectively to arrange in the situation on the top of washing and dewatering groove 9, but also can arrange respectively a plurality ofly, setting position also can arrange near the centre of the short transverse of washing and dewatering groove 9.
