Fig. 1 is the cutaway view of general structure of the tumbling-box washing machine of an expression embodiment of the present utility model.In Fig. 1, the tumbling-box washing machine of present embodiment has according to pattern setting, control program and controls the function that motor 6, water supply mechanism 7, drainage mechanism 8, drier 9 carry out washing procedure, rinsing process, dehydration procedure, drying process at least automatically with identical in the past.But drier 9 is optional.

And, in the present embodiment, also has following function simultaneously: as required, when washing during preparatory process, washing procedure, during rinsing process etc., utilize water circulation mechanism 16 make water circulations in the tank 3 realize washing agent dissolving in advance, prevent from biasing to improve the function of washing, rinsing.Water supply mechanism 7 is the mechanisms that set screw clamp 3 from running water bolt of outside etc.Water supply mechanism 7 can utilize the switching of electromagnetic valve and such in good time water supply shown in the solid line arrow.In addition, can utilize water supply that the washing agent of washing agent resettlement section is put in the tank 3 in good time.

Drainage mechanism 8 is adapted to from tank 3 to externally drained.The switching that drainage mechanism 8 can utilize draining valve 19 draining like that shown in chain-dotted line in case of necessity such as when washing procedure finishes, when rinsing process finishes.Drier 9 is adapted to air is circulated between air blast 12 and tank 3.

Drier 9 has the dry cycle path, and this dry cycle path utilizes air blast 12 that the air in tank 3 and the swing roller 4 is circulated as dotted arrow.Be equipped with filter 15 on this dry cycle path, this filter 15 is used for the airborne the end of a thread class from tank 3 and swing roller 4 importings is captured and dedusting.On this dry cycle path, also be equipped with the dehumidification portion 10 that the importing air after the dedusting is dehumidified.In addition, the air after being equipped with heating and dehumidification on this dry cycle path and form the heating part 11 of dry high temperature air.By air blast 12 being configured in the downstream of heating part 11, be difficult to be subjected to the influence of moisture.Dehumidification portion 10 and heating part 11 be by compressor 17 make cold-producing medium circulation and with evaporimeter and condenser that circulating air carries out heat exchange, constitute air-conditioning 18.But drier 9 is not limited thereto.

Water circulation mechanism 16 is recycled circulating pump 20 and is sucked the water in the tanks 3 and it is turned back to tank 3.

The selection of operation process isotype, various functions is undertaken by the input of the guidance panel 21 on the front surface top that is located at body of the washing machine 2.Controlling organization 22 shows based on this input information and by the display part on the guidance panel 21 notifies the user.Utilize the input configuration part of guidance panel 21 to set when turning round beginning, the input data such as water level detecting portion from detecting the water level in the tank 3 begin driving.Thus, the action of control draining valve, feed water valve etc. is washed, is dewatered, the running of drying etc.

The rotating shaft 4a that is installed in motor 6 and swing roller 4 on the tank 3 directly links, and swing roller 4 together is provided with towards bottom side ground from open side from the obliquely-angled θ of horizontal direction=20 ± 10 degree ground with rotor shaft direction with tank 3.Thus, even swing roller 4 is arranged to the height identical with the situation that rotating shaft 4a is set in the horizontal direction, the opening of tank 3 and swing roller 4 also is tilted to, so the user can need not to adopt the posture of efforts such as bending over just can easily take out, put into washings.Particularly according to inventor's etc. experience, by the angle of inclination being made as 20 ± 10 degree, even taking-up that height gap from child (except the child) to the adult or wheelchair user also can both obtain to be easy to most carry out washings is arranged, put into the state of operation.In addition, because the water that is fed in the swing roller 4 accumulates in rear side, even therefore have a spot of water also can obtain the advantage of darker water storage state.Tank 3 is for the water that makes supply acts on washings in the swing roller 4 expeditiously, have with swing roller 4 same tilt ground near swing roller and be provided with.In addition, on body of the washing machine 2, be provided with shutter door 5, by means of the seal 14 of the edge portion of the opening 13 that is installed in tank 3 with opening 13 sealings of tank 3 or open.

In addition, the driving of swing roller 4 is for example carried out dehydration procedure with the high-speed so continuous rotation of 1000rpm.Therefore, washings keep in washing procedure, the rinsing process winding, reverse, wrinkling state abuts in the inner surface of swing roller 4 and has fold.Its result is difficult to take out washings, handles spended time and labour afterwards.And easy residual serious fold on washings removes the more time and labor of wrinkle cost.

In order to address this problem, in the present embodiment, or/and in the rinsing process,, be difficult for producing wrinkling simultaneously in order to improve the generation of twining, reversing, the effect that improves mechanical force significantly at washing procedure, control with following 2 patterns.The 1st pattern be alternately repeat swing roller 4 change drive pattern greater than 90 degree and the positive and negative hooks that change less than the quick positive arcs rotation of 180 degree, quick anti-hooks.The 2nd pattern is positive and negative continuous rotation drive pattern, and positive and negative alternate repeats to represent the continuous rotation of the above-mentioned swing roller 4 of upborne washings under the rotary speed of the action that the height and position that its deadweight is dominant falls by the rotation of swing roller 4.In washing procedure or washing procedure and rinsing process, alternately carry out positive and negative hook and change drive pattern and positive and negative continuous rotation drive pattern.Thus, by changeing and brake hard greater than 90 degree and less than the 180 quick hooks of spending of swing roller 4, making washings upborne is greater than 90 degree and less than 180 degree to greatest extent.And, the brake hard that the final stage of washings is lifted in utilization produces on-position, utilize the inertia and the deadweight of washings that washings is peeled off from the inner surface of swing roller 4, utilize its deadweight to make it can drop to and lift the heterochiral side of side reliably.Therefore, can be especially fully expand, wetting, and the washings that is in the state of lax, easy slip applies the higher effect of untiing, and can give washings action mechanical power, so can improve washing (-)off properties containing water.And, change the quick positive arc rotation of the forward that drives and reverse quick anti-hook commentaries on classics by alternately repeating hook, also can carry out positive and negative hook and change drive pattern.Thus, the quick hook by positive and negative alternate changes and drives, and changes driving at each hook, about alternately change cocked position, the lowering position of washings.Therefore, Yi Bian untie effect Yi Bian can avoid washings to twine more to improve more, and can increase the number of times of the suffered mechanical force of washings, therefore can improve washing (-)off properties.In addition, utilize the high effect of untiing, can be suppressed at wash, washings produces winding each other during rinsing process.Thus, carry out effectively beating of positive and negative hook revolving die formula constantly and wash, can improve and clean effect and wash effect.

In addition, only change drive pattern with positive and negative hook, the winding of washings, reverse, wrinkling etc. being alleviated, and be difficult to change the position of washings above-below direction, the washings of swing roller 4 bottoms is difficult to motion, be easy to generate wash inhomogeneous., with positive and negative continuous rotation drive pattern, can realize the position transposing of washings above-below direction by also.That is, the washings that alleviates positive and negative continuous rotation drive pattern twines, reverses, wrinkling, and alleviates the mechanical force that acts on washings unbalanced that positive and negative hook changes drive pattern.Utilize two-mode thus and can apply 2 kinds of different actions the washings in washing, the rinsing.That is, specifically, utilize positive and negative hook to change drive pattern, alleviate washings winding, reverse, wrinkling and can apply the action that reliable hand rubbing is washed.In addition, on one side utilize positive and negative continuous rotation drive pattern to make washings continuous motion significantly,, strong spot is applied evenly and effectively washing action one side alleviate inhomogeneous the washing.

In drying process, when particularly carrying out positive and negative hook and changeing drive pattern, the fold of the washings after the dehydration is launched, significantly improving laundry and finishing quality, alleviate the operation of back significantly.But, exist the washings of drying process to be difficult to abut in gently situation on the inner surface of swing roller 4, therefore preferably the anglec of rotation of swing roller 4 is set at more than or equal to 90 ° and less than 200 °.

The maximum speed of the swing roller 4 of positive and negative Continuous Drive pattern is 45 ± 5rpm as that works usually, and the maximum speed that positive and negative hook changes the swing roller 4 of drive pattern is more than the 40rpm in washing, rinsing process, and the dehydration back is that 50rpm is above preferable.

But, as in the past, when the circulating pump 20 that makes the water circulation in the tank 3 was arranged on platen 2a as the bottom of body of the washing machine 2 and goes up, the setting that connects the water circulation path of circulating pump 20 and tank 3 was restricted.That is, the distance between each link position between the tank 3 that is subjected to being fixed on the circulating pump 20 of the fixation side on the platen 2a and vibrating side, the such restriction of variation of position skew.Therefore, need be connected with having the retractility that can absorb this variation, flexible flexible pipe etc.Measurable is that this flexible pipe is because vibration, flexible and aging in advance along with the vibratility of vibrating repeatedly produces the situation of leaking to its result.

Therefore, in the present embodiment, will the water in the tank 3 be arranged on the tank 3 by the circulating pump 20 that water circulation path 31 circulates.And, as shown in Figures 2 and 3, when being arranged on the water circulation of tank 3, the filter 32 of the water of filtration cycle sucks in the water suction portion 33 of water.Fig. 2 is the water suction portion of tumbling-box washing machine of present embodiment and the cutaway view of drain outlet portion.Fig. 3 is the water suction portion of tumbling-box washing machine of present embodiment and the vertical view of drain outlet portion.

Like this, when circulating pump 20 was installed on the tank 3, the water circulation path 31 that is connected with each other with their connections was installed on the same tank 3 with circulating pump 20.Thus, can avoid the variable in distance between each link position, or produce the position skew owing to the vibration of tank 3.Therefore, the water circulation path 31 between circulating pump 20 and the tank 3 does not need retractility and flexible.And, as long as water circulation path 31 makes water at tank 3 be installed in circulation between the circulating pump 20 on this tank 3, therefore make the interior water circulation of tank 3 with conduits structure short and that be beneficial to durability.And circulating pump 20 does not become when driving under the state of the washings existence biasing of swing roller 4 and strengthens the such vibration source of vibration that tank is subjected to, thereby can play the damping effect of circulating pump 20 weight degree to tank 3.

And filter 32 is arranged at sucking the water suction portion 33 of water from tank 3 of water circulation path 31 to face in the tank 3 and to the state that exposes in the tank 3.Therefore, can prevent that the end of a thread class from entering into influent side path 31a, the circulating pump 20 of water circulation path 31, not need to safeguard.

As mentioned above, circulating pump 20 together is installed on the tank 3 with water circulation path 31, therefore between the link position of circulating pump 20 and water circulation path 31, between the link position of tank 3 and water circulation path 31, variable in distance and the position skew that can avoid the vibration by tank 3 to cause.And water circulation path 31 is short and conduits structure is simple, can adopt the material that does not need retractility, flexible and vibration resistance excellence, can adopt resin molded part etc. specifically.Therefore, water circulation path 31 can adopt simple and volume little, the material of low cost and excellent in te pins of durability, makes the water circulations in the tank 3 when being necessary and improves the function of washing machine.And it is vibration source that circulating pump 20 is not really for tank 3, can suppress the increase of the vibration of tank 3 by the damping effect of weight, can seek to guarantee quiet running and prevent that the life-span from reducing.Therefore, circulating pump 20 be installed in weight balancing with respect to tank 3 good, circumferentially and the bottom of axis direction preferable.And filter 32 is arranged in sucking in the water suction portion 33 of water and can avoid the end of a thread class to enter into the influent side path 31a of circulating pump 20 and water circulation path 31 from tank 3 of water circulation path 31.Therefore, do not produce the end of a thread class card extension or accumulation or strand and go in the influent side path 31a and circulating pump 20, thus obstruction, damage, the breakage that can not produce water circulation system 16.Therefore, just can not guarantee the safe, stable of do action for a long time to the special maintenance of the end of a thread class.

At this, Fig. 4 is the stereogram of major part structure of the tumbling-box washing machine of expression present embodiment.Fig. 5 A～Fig. 5 C is cutaway view, side view and the upward view of circulating pump that is used for the tumbling-box washing machine of this embodiment.As shown in Figure 4, circulating pump 20 is connected to the bottom 3b of tank 3 and fixes with bolt 34 grades from the below.As Fig. 1～shown in Figure 4, the place ahead of the body of the washing machine 2 that the discharge side path 31b that the self-circulating pump of water circulation path 31 is 20 is positioned at towards the opening 13 of tank 3 is to tilt more than 20 ° with horizontal direction and up extends.Specifically, shown in Fig. 5 A～Fig. 5 C, the resinous pump case 20b that contains impeller 20a of circulating pump 20 forms integrated in its open side with the bearing next door 20d1 butt of the front end of the metal motor field frame 20d that is in circulation 20c.Impeller 20a and motor reel 20e directly link, and circulating pump 20 is inlaid on the resinous mount pad 35.Mount pad 35 has the roughly installation sheet 35a of C type at its peripheral 3 places (Fig. 5 C).As shown in Figure 4, make above-mentioned installation sheet 35a chimeric with the lug boss 3c of outstanding setting, bolt 34 is screwed among the lug boss 3c towards the below from the bottom 3b of tank 3.The axis of circulating pump 20 thus, circulating pump 20 is installed on the bottom 3b of tank 3 from the below, even also can not become obstacle for the top that vertical and circulation 20c are positioned at pump case 20b.

Thus, can be below the tank 3 when safeguarding dismounting circulating pump 20 easily.In addition, can tilt or/and realize discharging side path 31b by swing roller 4 from the circulating pump 20 of the such low level in the below of the bottom 3b that is in body of the washing machine 2 rear portion side that become tank 3 along the shortest pipe arrangement of drum along tank 3.That is, towards the front portion of body of the washing machine 2, up extending from the horizontal by tilting more than 20 °, is not complicated structure.Circulating pump 20 sucks the water in the tank 3 by influent side path 31a, and is sent to and discharges among the side path 31b and be discharged in the tank 3.At this moment, the discharge side path 31b of inclination successfully makes in the air from pump housing 20b and discharges to discharging side path 31b.Therefore, can prevent to produce circulating pump 20 is involved in air the so-called entrained air in the water in pump case 20b phenomenon.Therefore, carry out the maintenance of the special circumstances of circulating pump 20 easily.At this, when the angle of inclination of swing roller 4 is 20 ° ± 10 °, as the situation that produces the condition enactment that surpasses swing roller 4 angles of inclination with acclivitous discharge side path 31b more than 20 °.But, as long as the curved shape of the circumferential barrel surface of comprehensive utilization tank 3 just can form the shortest pipe arrangement that does not separate with tank 3.

And as shown in Figure 2, circulating pump 20 correspondingly tilts a little with the inclination of tank 3, but from axis towards the bottom of pump case 20b longitudinally, specifically by with the suction inlet 20f water inlet of the integrally formed L font in bottom.Afterwards, from the perisporium of tank 3, discharge by tangentially integrally formed outlet 20g (Fig. 4) specifically.Therefore, as shown in Figure 2, the foot 31c of pump case 20b and water circulation path 31 is positioned at than the high position of draining valve 19 that is arranged on the drainage channel 8a that the water that is used for tank 3 is discharged to outside drainage system 8, communicates with the height and position with below the draining valve 19 upstream equal heights of drainage channel 8a.That is to say the foot 31c of pump case 20b and water circulation path 31 and draining valve 19 upstream equal heights or extend ground downwards and link to each other with the upstream position of the draining valve 19 of drainage channel 8a.When opening draining valve 19 like this, the water in pump case 20b and the water circulation path 31 is just from all flowing in the drainage channel 8a naturally with their common foot 31c.

Thus, the foot 31c of pump case 20b and water circulation path 31 becomes the position of residual water nature diffluence of the inside of circulating pump 20, drainage channel 8a.Drainage channel 8a is communicated in the height and position below the upstream equal height with draining valve 19.Thus, when opening draining valve 19 drainings, the water that remains in water circulation path 31 and the circulating pump 20 is discharged naturally by drainage channel 8a.Therefore, water circulation path 31 comprises circulating pump 20, and inner residual water is discharged from along with the discharge of the water in the tank 3, does not need independent drain structure, draining control.

At this, as shown in Figure 2, drainage channel 8a and water circulation path 31 have formed water receiving housing 37 and total water receiving housings 37, and this water receiving housing 37 is used for the water discharge outlet 36 and water suction portion 33 water receivings that are connected from the drainage channel 8a of tank 3.Water receiving housing 37 has to the water inlet pipe arrangement zone 37a of circulating pump 20 sides water inlet with to the drainage piping zone of drainage channel 8a side draining 37b.Thus, will accept by being formed on 1 water inlet pipe arrangement zone 37a and drainage piping zone 37b on the water receiving housing 37, simplify the structure of water receiving, the structure of sealing from the water inlet of the water suction portion 33 of tank 3 with from the draining of water discharge outlet 36.Corresponding by the water inlet that water inlet pipe arrangement zone 37a accepts with the water inlet of having passed through water inlet path 31 to circulating pump 20.Corresponding by the draining that drainage piping zone 37b accepts with the draining of having passed through drainage channel 8a.When having such correspondence, water receiving housing 37 is discharged to the residual water of water circulation path 31 and circulating pump 20 among the drainage channel 8a naturally by drainage piping zone 37b when draining.That is water inlet pipe arrangement zone 37a that, can be by 1 integrally formed water receiving housing 37 and drainage piping zone 37b carry out from the water suction portion 33 of tank 3 water inlet, from the draining of water discharge outlet 36.Therefore, can be with simple and low-cost and be beneficial to water receiving structure, the seal construction of maintenance, passed through water inlet pipe arrangement zone 37a to the water inlet of circulating pump 20 and passed through the draining of drainage piping zone 37b.And, by drainage piping zone 37b the residual water of water circulation path 31 and circulating pump 20 is discharged among the drainage channel 8a naturally during draining, can not need special residual water to handle.

For this draining, in the present embodiment, as shown in Figure 2, the water inlet pipe arrangement of water receiving housing 37 zone 37a and drainage piping zone 37b are communicated with by being arranged on the intercommunicating pore 37d of the corresponding part of foot 31c of mutual next door 37c.On intercommunicating pore 37d, be provided with the non-return valve with anti-backflow function 38 that prevents from drainage piping zone 37b lateral intake pipe arrangement zone 37a side refluence water.Utilize the anti-backflow function from 37b lateral intake pipe arrangement zone, drainage piping zone 37a side of non-return valve 38, pass through filter 32, water inlet pipe arrangement zone 37a, influent side path 31a from water suction portion 33, when circulating pump 20 water inlets, the water that is mixed with the end of a thread class can be from 37b side inflow water inlet pipe arrangement zone, drainage piping zone 37a side.Therefore, utilize circulating pump 20 that the water in the tank 3 is circulated no problemly.And, drainage piping zone 37b when having passed through to have opened draining valve 19, during from drainage channel 8a draining, the residual water in water circulation path 31 and the pump case 20b is opened the non-return valve 38 of intercommunicating pore 37d, flow to drainage piping zone 37b side, therefore can not hinder natural drainage.And, do not need complicated especially structure from the anti-backflow function of 37b lateral intake pipe arrangement zone, the drainage piping of non-return valve 19 zone 37a side.

But, be not limited to above-mentioned embodiment, the prescribed limit of the water inlet pipe arrangement zone 37a of water receiving housing 37 and drainage piping zone 37b next door 37c, be connected with the area bigger specifically, at this interconnecting part not shown filter can be installed integrally formed filter screen portion maybe can be set than intercommunicating pore 37d.The non-return valve of the interconnecting part of drainage piping zone 37b and water inlet pipe arrangement zone 37a also can be set thus.Thus, come the water sorption of self-circulating pump 20 not only to act on into water pipe arrangement zone 37a, also affact drainage piping zone 37b by interconnecting part.But,, therefore can not affact the more downstream of the draining valve 19 of drainage channel because draining valve 19 is closed.Therefore, except the water inlet of having passed through filter 32, water inlet pipe arrangement zone 37a from water suction portion 33, passed through water discharge outlet 36, drainage piping zone 37b and the filter of interconnecting part, the water inlet of filter screen portion and also carried out abreast, do not entered the end of a thread class and seek to reduce the water inlet resistance.And, during the drainage channel 8a draining of the drainage piping zone 37b when having passed through to have opened draining valve 19, residual water in water circulation path 31 and the pump case 20b flows to drainage piping zone 37b side by filter, the filter screen portion of interconnecting part, does not therefore hinder natural drainage.And the residual water in water circulation path 31 and the pump case 20b is not sneaked into the end of a thread class, so the end of a thread class is filtered and can be caught in into that water pipe arrangement zone 37a flows to the regional 37b side of drainage piping interiorly, so does not hinder natural drainage.Even the adhering to that the end of a thread class is not washed away by draining of when water inlet and, also can make it flow into drainage piping zone 37b side and natural drainage on the contrary in contrary mode of cleaning still attached to the drainage piping zone 37b side of filter, filter screen portion.Therefore, can not need to be used for to remaining in the special maintenance of the end of a thread class in residual water, influent side path 31a, the drainage channel 8a.

As shown in Figure 2, water suction portion 33 and filter 32 are in the high position of water discharge outlet that the drainage channel 8a than tank 3 is connected 36, and the position less than lowest water level when being positioned at water circulation, do not hinder water the flowing to water discharge outlet 36 in the tank 3.In the present embodiment, filter 32 be inlaid in be opened on tight adjacent and than in the water suction portion 33 of water discharge outlet 36 by last position, this water discharge outlet 36 is opened on the 3d of lowest order portion of the perisporium of tank 3 with water discharge outlet 36.That is, the upper surface of the general planar of filter 32 is in the position higher slightly than the perisporium inner surface of tank 3, and block water does not flow to water discharge outlet 36.Therefore overlook filter 32, its rounded or ellipse etc. also can be the structure of dome-shaped or chevron for protuberance upwards.But, even preferably be restricted to the following height of lowest water level, promptly be restricted to draining from lowest water level, the flowing of water when filter plane is also utilized the draining of this lowest water level and be subjected to flushing action described later.

Like this, in the present embodiment, water suction portion 33 and filter 32 are on the water discharge outlet 36 of tank 3, below the lowest water level when being positioned at water circulation, and, have the water that do not hinder in the tank 3 the structure that flows to water discharge outlet 36.Therefore, filter 32 filters but is not separated by with tank 3.Thus, even the end of a thread class, is exposed to the current that reduced the water yield in the tank 3 attached to the surface of filter 32 when draining, in the current that water discharge outlet 36 is gone and be rinsed.Its result is mixed in the draining and is discharged from filter and filter screen portion being arranged on the end of a thread class of adhering to sometimes when drainage piping zone 37b goes up, and therefore can avoid the end of a thread class to be accumulated in filter part when each do action.Therefore, can not need to be used to remain in the special maintenance of the end of a thread class in residual water, influent side path 31a, the drainage channel 8a.

At this, Fig. 6 is the stereogram of filter of the tumbling-box washing machine of this embodiment of expression.Fig. 7 is the front view of filter installation portion of the tumbling-box washing machine of this embodiment of expression.As Fig. 2, shown in Figure 6, the filter 32 of water suction portion 33 is opened on water suction portion 33, forms the water inlet 39 big coating spaces 41 that connected than influent side path 31a and coats water inlet 39.Therefore, filter 32 is cooperated with its inboard coating space 41, guarantees the water flowing zone bigger than water inlet 39, and this whole water flowing zone communicates with water inlet 39 via coating space 41, because the water flowing zone is bigger and be difficult to produce when water flowing and stop up than water inlet 39.Meanwhile, also with tank in the flushing of the current that produce interact, suppress to stop up the pressure loss that is caused the flow of regulation in guaranteeing easily to circulate.To this, preferably total aperture area of the filter 32 of water suction portion 33 is set greater than the aperture area of water inlet 39.Thus, in than the big water flowing zone of the water inlet 39 of filter 32, guarantee the total aperture area bigger, can prevent to stop up, further reduce the water flowing resistance than the aperture area of water inlet 39.Therefore, guarantee effectively to utilize the water flowing zone bigger, can prevent to stop up and further reduce the pressure loss than the water inlet 39 of filter 32 than the big total aperture area ground of the aperture area of water inlet 39.

At this, comprise filter loading hatch 42, make the bottom 41b of installed filters 32 to cover to the opening 41a that exposes in the tank 3, to the part beyond the coating space 41 in the face of the mode in the tank 3 towards the front portion as the formation portion of the coating space 41 of filter resettlement section.Bottom 41b is communicated with water circulation path 31.Like this, the formation portion of coating space 41 constitutes simple box-shaped attitude, can be by the contour forming that is attended by by the simple molding of filter loading hatch 42, and perisporium easy and tank 3 is configured as one, does not need special member.Therefore, the structure that removably is provided with of filter 32 does not become the reason that cost rises.

And, as shown in Figure 2, will be housed in formation portion by the heater 71 that heat cycles water improves washing, wash effect as the coating space 41 of filter resettlement section.The shared filter loading hatch 42 of heater 71 energy can load and unload in the same manner with filter 32.In addition, heater 71 also can be provided with the heater loading and unloading mouthful of the special use different with filter loading hatch 42, loads and unloads from the outside of tank 3.In addition, as shown in Figure 2, when heater 71 being configured among the recess 32d at the back side of filter 32, just can load and unload simultaneously with filter 32.But, need take following countermeasure:, set in advance and have with the electric connection part of the insulation structure of the power supply insulation that is arranged on tank 3 outsides etc. in the installation site of filter 32.

More describe in detail, in the present embodiment, as Fig. 2, Fig. 6, shown in Figure 7, filter 32 comprises by loading hatch 42 and inserts insertion section 32a in the coating spaces 41, finishes the flange part 32b that loading hatch 42 is sealed when being inserted in the coating space 41.With filter 32 when coating space 41 inserts, flange part 32b have with the peristome front surface of loading hatch 42 near or butt and containment member 47 that loading hatch 42 is sealed.And, be shaped and on the 32a of insertion section, form filter 32 thereby carry out the hole, at the front surface formation grip 32c of flange part 32b and load and unload easily by finishing die.

According to such structure, between by filter loading hatch 42 installed filters 32 and filter loading hatch 42, do not need special operation, make chimeric pressure or chimeric pressure and setting pressure act on containment member 47 and easily and reliably filter loading hatch 42 is sealed, can prevent because of leaking that the filter mounting and detaching structure causes.

And lax for the lax and sealing of the casual insertion that prevents to cause because of the vibration of tank 3 etc. as shown in Figure 2, is provided with by screw 48 flange part 32b to be tightened and is fixed on the installing hole 49 that tank 3 sides are used.And, insertion section 32a has protuberance 32a1, this protuberance 32a1 finishes under the state of insertion, under filter 32 and the closely chimeric state of the opening 41a of the coating space 41 of tank 3, makes insertion section 32a be the state that exposes of the state of outstanding ormal weight or regulation in tank 3.And, in the 32a of insertion section,, lower and towards the inserting side than protuberance 32a1 in exterior circumferential protuberance 32a1, except flange part 32b, promptly towards the back side of body of the washing machine 2,32a2 of locating flange portion and protuberance 32a1 that side-looking is wedge type form as one.The side-looking of flange part 32a2 below the opening edge of the opening 41a of the coating space 41 that is formed on tank 3 is the gathering sill 41b guiding of wedge type.Thus, insertion section 32a is inserted into the insertion completing place of regulation easily and reliably, is fixed to the outstanding state of regulation or exposes state.

At this, front view, sectional elevation and the longitudinal section of Fig. 9 A～Fig. 9 C pipeline that to be expression be connected the water circulation path and the discharge side path of the tumbling-box washing machine of present embodiment.Shown in Fig. 1, Fig. 4, Fig. 9 A～Fig. 9 C, the discharge side path 31b of water circulation path 31 is connected with the ejiction opening 51 of the foot of front bulkhead 3h around the opening 13 that is arranged on tank 3 from the outside.Thus, between the surface of the front bulkhead 4b of the back side of the front bulkhead 3h of tank 3 and corresponding with it swing roller 4, spray, be discharged in the swing roller 4 by the stream 52 that between them, forms from the recirculated water of discharging side path 31b.According to such structure, from the ejiction opening 51 of the water of discharging side path 31b be in swing roller 4 in the discontiguous position of washings, therefore can prevent that washings from being tangled and upset necessary operations such as washing, rinsing, drying etc., or damage or stave washings etc.Therefore meanwhile, stream 52 is formed between front bulkhead 3h, the 4b of tank 3 and swing roller 4, does not need special member and simply and has at an easy rate realized using the such structure of containment member 56, reduces the risk of leaking.The action of the left-right reversed washings when changing the action of washings and positive and negative hook up and down and change drive pattern by combination under positive and negative continuous rotation drive pattern more improves the jeting effect of recirculated water.

And shown in Fig. 9 C, at the back side of the front bulkhead 3h of tank 3, ejiction opening 51 is towards the pivot direction opening of swing roller 4.Specifically, the ring-type towards the stream 52 between front bulkhead 3h, the 4b of tank 3 and swing roller 4 exports 53 openings.Therefore, the recirculated water that sprays from ejiction opening 51 is discharged to the stream 52 expeditiously towards the pivot side of swing roller 4.Specifically, radially be discharged to the inboard rotary area of swing roller 4 expeditiously towards ring-type outlet 53.Therefore, no matter what of washings can provide recirculated water expeditiously.The front bulkhead 3h of tank 3 has inclined plane 3h1 and flexure plane 3h2.Inclined plane 3h1 tilts from the position corresponding with ejiction opening 51 towards near the rear portion side to body of the washing machine 2 interior week.Flexure plane 3h2 is from inclined plane 3h1 open side bending of 4 to interior week towards swing roller.By having the front bulkhead 3h of inclined plane 3h1 and flexure plane 3h2, the solid arrow shown in Fig. 9 C is such, and the recirculated water that is ejected into stream 52 is discharged from inclined plane 3h1 along flexure plane 3h2.That is, be ejected into the opening of recirculated water by swing roller 4 in the stream 52, discharge, therefore can improve the efficient that recirculated water is provided to washings towards the inboard of swing roller 4.

At this, shown in Fig. 9 A～Fig. 9 C, ejiction opening 51 has the connector 51a on the front bulkhead 3h that is formed on tank 3.Ejiction opening 51 is ejected into recirculated water the stream 52 from the connector 51a that discharge side path 31b is connected.Ejiction opening 51 towards the pivot side of swing roller 4 ground in circumferential prescribed limit to stream 52 openings.Like this, on the front bulkhead 3h of tank 3, be provided with connector 51a, be formed with ejiction opening 51 to stream 52 openings.Thus, to not be directed to stream 52 sides mussily by ejiction opening 51 from the recirculated water of discharging side path 31b, from stably being discharged in the swing roller 4 along prescribed direction along with to the left and right expansion with the corresponding regulation of the circumferential zones zone of the ejiction opening 51 of ring-type outlet 53.Therefore, though can swing roller in 4 washings what and recirculated water is provided effectively.

And between the connection end 55d and connector 51a of the discharge side path 31b that connector 51a is connected, ejiction opening 51 is with the peristome guiding of recirculated water to stream 52.Thus, be arranged on the ejiction opening 51 of discharging on the connector 51a that side path 31b connected recirculated water be directed to stream 52 sides in order to make, can by with is connected the mutual simple shape that end 55d cooperates and constitutes connector 51a.According to so simple formation, no matter what of washings can both suitably carry out the supply of discharging current thickness fully, can increase the recirculated waters such as discharge water velocity of water distance along circumferential big discharge flow width, fore-and-aft direction.And conduits structure is not complicated especially, does not increase the risk of leaking yet, and does not become the reason that cost rises yet.

And, ejiction opening 51 shown in Fig. 9 A～Fig. 9 C like that at about center opening of the bottom of the front bulkhead 3h of tank 3.Ejiction opening 51 is connected by the resinous pipeline 55 shown in Fig. 4, Fig. 9 A～Fig. 9 C with discharge side path 31b.Pipeline 55 be before and after both involutory and flat before and after forming of member 55a, 55b.Discharge side path 31b with respect to the aperture position of ejiction opening 51 to the left and right the either party of direction dispose partially, forwards extend from the axis almost parallel ground of circulating pump 20 with tank 3.Pipeline 55 couples together front end and the ejiction opening 51 of the discharge side path 31b of tubulose.That is, the connecting pipe 55c that is integrally formed on the end of back member 55b is connected with discharge side path 31b as its extension.Front part 55a is after the distolateral approximate horizontal ground of back member 55b extends near the below of ejiction opening 51, and bending erects ejiction opening 51, forms connection end 55d.Shown in Fig. 9 C, on connection end 55d, be formed with back member 55b integrally formed connector 55e.Connector 55e is connected with connector 51a on the front bulkhead 3h of opening at tank 3 across containment member 56, tightens and is fixed with screw 57.Like this, make the connection end 55d that is connected from the connector 51a of the front bulkhead 3h of tank 3 to the periphery of tank 3 stretch out and the pipeline 55 that is connected with circulating pump 20 sides form before and after flat.Thus, can pipe be configured between the front side wall of the front bulkhead 3h of tank 3 and body of the washing machine 2 with little space.And, utilize the flat pattern of pipeline 55, recirculated water is rectified into corresponding flow widths such as opening, current thickness with ejiction opening 51.Thus, recirculated water 51 is ejected into the stream 52 from connector 51a towards ejiction opening, the velocity of discharge territory that big circumferential discharge width, the fore-and-aft directions that current are not satisfied mussily discharge from ring-type outlet 53 are discharged thickness fully, can increased the water distance.Its result further improves washing, wash effect.And pipeline 55 extends transversely near the below the connector 51a of ejiction opening 51 of front bulkhead 3h bottom from the periphery of tank 3, and is connected with connector 51a by the rising portions that bends to connector from here.Therefore, the recirculated water that utilizes the curved shape of rising portions will be rectified into flat current is not directed to the ejiction opening 51 of connector 51a and the alignment of flat direction mussily, is ejected into the circumferential regulation zone of stream 52.Therefore, more stably discharge, improve the effect of recirculated water washings from the wideer zone of ring-type outlet 53.

Particularly utilize with the connector 51a of opening on the front bulkhead 3h of tank 3 meet at right angles near the front bulkhead 4b side of swing roller 4 and and the integrally formed barrier 5c of this connector 51a, ejiction opening 51 forms between the rising wood of barrier 5c and connector 51a and exports 53 openings towards ring-type.Between connection end 55d and barrier 5c, have towards ejiction opening 51 and make and spray path dwindles bore smoothly with arc surface from pipeline 55 sides throttling wall 55f.Thus, to from pipeline 55 towards ejiction opening 51 recirculated water energize and make it to become tightly along the inclined plane 3h1 at the back side of the front bulkhead 3h of tank 3 and the high velocity stream of flexure plane 3h2.Therefore, recirculated water is discharged in the swing roller 4 with the reliable geosyncline of regulation path back upper place, on one side about expansion offer washings in the swing roller 4 from wider zone with parabolical longer flight path on one side.But the throttling path that is used to form high velocity stream also can at random be formed between the connection end 55d and ejiction opening 51 that are connected to connector 51a of pipeline 55.That is to say, utilize the ejiction opening 51 that is arranged on the connector 51a, the recirculated water that flows into is directed to stream 52 sides.At this moment, utilize and the corresponding mode of the simple shape that is connected end 55d that is connected to connector 51a of discharging side path 31b, no matter what of washings can both carry out preferably satisfying the guiding that circumferential big discharge flow width, fore-and-aft direction discharged current thickness fully, can increased the conditions of work such as discharge water velocity of water distance.And conduits structure is not complicated especially, does not increase the risk of leaking, and does not become the reason that cost rises yet.

And, shown in Fig. 9 C, on the front bulkhead 4b of swing roller 4, be formed with the rib shape protuberance 4c of stream 52 along circumferentially transversal ring-type.Between rib shape protuberance 4c and inclined plane 3h1, reserve throttle clearance S ground and form rib shape protuberance 4c.And the position of this rib shape protuberance 4c is fluctuations radially.Therefore, rib shape protuberance 4c makes the transverse location with respect near the stream 52 the ejiction opening 51 when swing roller 4 rotation, the formation position that is about to throttle clearance S in Fig. 9 C like that radially to change shown in 3 particular locations (solid line and dotted line).Its result, following situation takes place in the circulating water flow towards ring-type outlet 53 in stream 52: near ring-type outlet 53 by throttle clearance S throttling, exporting 53 position away from ring-type by throttle clearance S throttling.Thus, recirculated water is offset up and down towards the angles in the swing roller 4, therefore in the wide zone of the axis direction of swing roller 4 recirculated water is separately offered washings.

At this, rib shape protuberance 4c is along the discharge guiding piece on the front bulkhead 3h side that circumferentially is arranged on swing roller 4 unevenly.Therefore, make the disorderly or variation in discharge direction front and back that is ejected in the stream 52 and is discharged to the recirculated water in the swing roller 4 from ring-type outlet 53.Therefore, make discharge the washings of recirculated water in swing roller 4 water level disorderly or change before and after putting.As such discharge guiding piece, as along the interior week that circumferentially rises and falls, along the wall that rises and falls forwards, backwards in week, to stream side-prominent and along circumferentially rising and falling or/and interrupted rib shape protuberance or blade, make the recirculated water that sprays by stream pass through resistance along in the obstruction portion that circumferentially changes at least one, can play to make and discharge the effect that the direction front and back are disorderly or change, as far as possible they are used in combination.
