In addition, water system 7 can be passed through the switching of electromagnetic valve (not shown), as in time supplying water with that kind shown in the solid arrow.In addition, can utilize water supply in time the washing agent of washing agent resettlement section (not shown) to be put in the tank 3.Drainage system 8 can be through draining valve 19 switching, when matting finishes, when rinsing process finishes etc. necessary the time shown in dotted arrow the water in such discharge tank 3.In addition, water circulation path 16 repeats following action: the washings that utilize circulating pump 20 to suck in the tank 3,16b is back in the tank 3 washings via the ejection side path.
Running program isotype, various function are selected in guidance panel 21 inputs through from the front surface top that is arranged on body of the washing machine 2.Control system 22 conveys a message to the user through various demonstrations according to the information of guidance panel 21 inputs is come the display part on the control operation panel 21.When setting entry into service through the input configuration part in the guidance panel 21, will be input to control system 22 and begin from the data of water level detecting portion etc. and drive, this water level detecting portion is detected the water levels in the tank 3.Then, the action of 22 pairs of draining valves of control system, feed water valve etc. is controlled, and cleans, dewaters, the running of drying etc.
In addition, the face side (left of Fig. 1) at body of the washing machine 2 is provided with body openings 2b.And, constitute and can washings be put into swing roller 4 or from swing roller 4 taking-ups via first opening 54 of second opening 13 of the face side that is arranged on tank 3 and the face side that is arranged on swing roller 4.Body openings 2b is provided with shutter door 5.Through shutter door 5 being opened or closed second opening 13 that perhaps to open tank 3 via seal member 14 sealings of the edge of opening that is installed in second opening 13.
In addition, as the drive pattern of swing roller 4, possessing forward and reverse hook changes drive pattern and positive and negative continuous rotation drive pattern.It is to make swing roller 4 change the pattern of rotating with opposite arc rapidly to carry out forward hook rapidly greater than 90 degree less than the anglec of rotation alternate repetition ground of 180 degree that forward and reverse hook changes drive pattern.In addition; Positive and negative continuous rotation drive pattern is following a kind of pattern: so that the deadweight of the washings that the rotation through swing roller 4 is lifted surpasses the rotating speed of the degree of the centrifugal force that the rotation by swing roller 4 produces, forward and reverse continuous rotation that alternately is rotated cylinder 4 repeatedly.
In matting or matting and rinsing process, alternately carry out forward and reverse hook and change drive pattern and positive and negative continuous rotation drive pattern.When forward and reverse hook changeed drive pattern, the hook that swing roller 4 is carried out in greater than the scope of 90 degree less than the anglec of rotation of 180 degree rapidly changeed and braking suddenly.Can washings be raised to greater than the anglec of rotation of 90 degree less than 180 degree thus.In addition, brake suddenly, can accomplish following action reliably: make washings because the heterochiral side of side is fallen and lifted in its inertia and deadweight and peel off from swing roller 4 inner surfaces through the terminal stage of lifting at washings.Thus, to washings are in abundant expansion and washings loose, that be prone to sliding state applies the high effect of rubbing out especially because of containing.In addition, owing to can apply mechanical force, therefore can improve cleaning performance to washings.And the hook of forward rapidly that carries out the positive direction that hook change to drive through alternate repetition ground changes and the rotation of reciprocal opposite arc rapidly, and that can about each hook changes in the driving, alternately change washings lifts position, lowering position.Can prevent further to improve the effect of rubbing out when washings tangles thus.In addition, owing to can increase the number of times that washings is applied mechanical force, therefore can improve cleaning performance.In addition, through tangling between the washings that the high effect of rubbing out can suppress to clean, rinsing process takes place.Thus, wash, can improve cleaning performance and wash effect through carrying out beating efficiently under forward and reverse hook commentaries on classics drive pattern continuously.
But, only utilize forward and reverse hook to change drive pattern, can alleviate the tangling of washings on the one hand, reverse, fold etc., be difficult to make the position of the above-below direction of washings to be changed on the other hand, be difficult to make the washings swing of swing roller 4 bottoms.Therefore, the cleaning that washings takes place easily is uneven, but can improve these problems through the positive and negative continuous rotation drive pattern of dual-purpose.That is, can realize the replacing of position of the above-below direction of washings through positive and negative continuous rotation drive pattern, can alleviate the tangling of washings, reverse, fold.In addition, it is unbalanced to alleviate the mechanical force that washings is applied that forward and reverse hook changes under the drive pattern.That is, change drive pattern and these two kinds of patterns of positive and negative continuous rotation drive pattern, can apply two kinds of different behaviors the washings in cleaning, the rinsing through using forward and reverse hook.Specifically, changeing drive pattern through forward and reverse hook is alleviating the tangling of washings, is reversing, in the fold, washings is being applied the behavior that reliable hand is rubbed cleaning.On the other hand, clean washings in uneven alleviating violent and continuous the waving of washings, washings is applied the behavior of cleaning efficiently to even and strong dirt through positive and negative continuous rotation drive pattern.
Circulating pump 20 is fixed on platen 2a.The ejection side path 16b that goes out self-circulating pump 20 in the water circulation path 16 extends towards the place ahead of second opening, the 13 present body of the washing machine 2 of tank 3.Specifically, shown in Fig. 2 A and Fig. 2 B, circulating pump 20 contains impeller 20a in resinous pump case 20b.In addition, the open side of pump case 20b is close to bearing rib 20d1 and forms as one with motor case 20d, and this bearing rib 20d1 is positioned at the front end of the motor case 20d of circulation 20c.Thus, impeller 20a and motor reel 20e directly link.The circulating pump 20 that forms by this way is inlaid in resinous mount pad 35.
End along the linking part 51 of horizontal expansion is connected with the bottom of bellying 3a, and the other end of linking part 51 is connected with the ejection side path 16b of water circulation path 16.Thus, washings are flowed in the water guide road 55b from ejection side path 16b.
In addition, roughly be the Y font cover 55 about each upper end be formed with shown in Fig. 5 A, Fig. 5 B such notch 55c that does not have hermetically-sealed construction.Thus, between the back side (medial surface) of the front bulkhead 3h of notch 55c and the tank 3 corresponding, form and have ejiction opening 55d to the opening of circumferencial direction area extension with it.In the 55b of water guide road with respect to disposing ejiction opening 55d respectively to side and right-hand end to side like the left of drop wire: this vertical line is the vertical line with respect to the face that is provided with at the center of first opening 54 that passes swing roller 4.
The washings that are recycled pump 20 pressurization flow into water guide road 55b via the ejection side path 16b of water circulation path 16 by linking part 51.The washings that flow into water guide road 55b be injected in by ejiction opening 55d tank 3 front bulkhead 3h the back side (medial surface) and and the lateral surface of the front bulkhead 4b of the swing roller 4 of its position in opposite directions between.Then, washings are ejected in the swing roller 4 via stream 52, and this stream 52 is formed between the lateral surface of front bulkhead 4b of the back side (medial surface) and swing roller 4 of front bulkhead 3h of tank 3.
Shown in Fig. 5 A, ejiction opening 55d is towards the pivot direction of principal axis of swing roller 4, jet 53 openings of the ring-type in stream 52 specifically.Thus, the washings that spray from ejiction opening 55d from stream 52 to the rotary middle spindle side of swing roller 4, specifically radially be ejected into the inboard rotary area of swing roller 4 efficiently to jet 53.Thus, can washings irrespectively be provided efficiently with what of washings.
And front bulkhead 3h possesses inclined plane 3h1, this inclined plane 3h1 from the interior Zhou Fangxiang of the corresponding position of ejiction opening 55d towards washing machine, tilt to the rear portion side of body of the washing machine 2.Also have guide surface 56, the end of the inboard (right side Fig. 5 A) of this guide surface 56 washing machine of 3h1 from this inclined plane is to first opening, 54 tilt and the extension of swing roller 4.Thus, shown in Fig. 5 A, 3h1 sprays to the inboard of swing roller 4 from first opening 54 of jet 53 via swing roller 4 along guide surface 56 from the inclined plane can to make the washings that are ejected into stream 52.Thus, can improve the efficient that washings are provided to washings.
At this, shown in Fig. 5 A, Fig. 5 B, constitute to a plurality of ejiction opening 55d the different guide surface in inclination angle 56,57 is set respectively.For example; Shown in Fig. 5 A; To be made as α from minute inclination angle of the corresponding guide surface 56 of ejiction opening 55d (right side Fig. 3 B) in top view and the left side of the water guide road 55b of expenditure, in addition, shown in Fig. 5 B; Will be from the water guide road inclination angle of the corresponding guide surface 57 of ejiction opening 55d (left side Fig. 3 B) on top view and right side of 55b be made as β, and establish α＞β.Refer to the angle between inclined plane 3h1 and guide surface 56 or the guide surface 57 respectively at this said inclination angle.Through this structure, as shown in Figure 6, from top view from the washings of the jet 53 in left side (arrow shown in Fig. 5 A a) as spray shape A to leaning on last direction to spray.On the other hand, spray to the below of spray shape A as spray shape B from the washings (the arrow b shown in Fig. 5 B) of top view from the jet 53 on right side.That is, the washings guide surface 56,57 different along the inclination angle that ejects from each ejiction opening 55d flows, and is ejected in the swing roller 4 via first opening 54 from jet 53.Therefore, can realize the injection different with respect to the rotary middle spindle spray angle of swing roller 4.
At this, the above-mentioned inclination angle also diffusion of the injection in the subtend swing roller 4 impacts.Under the little situation in inclination angle (for example under the situation of the structure shown in Fig. 5 B), from inclined plane 3h1 to guide surface 57 and near angle changes, 3h1 flows through the washings that come and sharply changes at guide surface 57 upper angles along the inclined plane.Therefore, become the state that washings impact guide surface 57.Under this state, take place to flow (for example the arrow b direction in Fig. 5 B flows), and flow to what circumferencial direction (along the direction of stream 52) spread along the incline direction of guide surface 57.Thus; Become the injection that has to the washings of the circumferencial direction of washing machine diffusion; That is, as shown in Figure 6, be the spray shape A of the washings that spray from the jet in left side 53 of α with respect to the inclination angle; The inclination angle is that the spray shape B of the washings that spray from the jet on right side 53 of β (relation that has as stated, α＞β) becomes the injection that has to the circumferencial direction diffusion.According to inventor's result of the test, be about 120 degree to the inclination angle, become the injection of washings large tracts of land diffusion, be under the situation more than 130 degree at the inclination angle, become the little membranaceous injection of diffusion.
In addition, as shown in Figure 7, can realize spraying diameter, the different washings of flow through the opening diameter that changes ejiction opening 55d from each ejiction opening 55d.In Fig. 7, towards body of the washing machine, the opening diameter of the ejiction opening 55d in left side (left side among Fig. 7) is D1, and the opening diameter of the ejiction opening 55d on right side (right side among Fig. 7) is D2 (D1＞D2).
In addition, the opening diameter of ejiction opening 55d is not limited to above-mentioned D1, D2, can suitably set.
