In addition, water system 7 can pass through the opening and closing of electromagnetic valve (not shown), in time supplies water as shown in solid arrow.In addition, water supply can be utilized in time to be put in tank 3 by the washing agent of washing agent resettlement section (not shown).Drainage system 8 can by the opening and closing of draining valve 19, discharges the water in tank 3 time necessary at the end of matting, at the end of rinsing process etc. as the dotted line arrows like that.In addition, water circulation path 16 repeats following action: utilize circulating pump 20 to suck washings in tank 3, via ejection side path 16b, washings is back in tank 3.
By selecting running program isotype, various function from guidance panel 21 input on the front surface top being arranged on body of the washing machine 2.Control system 22 carrys out the display part on control operation panel 21 according to the information inputted guidance panel 21, conveyed a message to user by various display.When setting entry into service by the input configuration part in guidance panel 21, the data from water level detecting portion etc. are input to control system 22 and start to drive, this water level detecting portion is detected the water level in tank 3.Then, the action of control system 22 pairs of draining valves, feed water valves etc. controls, and carries out cleaning, dewaters, dry etc. running.
In addition, the face side (left of Fig. 1) of body of the washing machine 2 is provided with body openings 2b.Further, be configured to washings to be put into swing roller 4 via the second opening 13 of face side and the first opening 54 of face side of being arranged on swing roller 4 being arranged on tank 3 or take out from swing roller 4.Body openings 2b is provided with shutter door 5.Can close or open the second opening 13 of tank 3 via the seal member 14 of the edge of opening being arranged on the second opening 13 by shutter door 5 is opened or closed.
In addition, as the drive pattern of swing roller 4, possess forward and reverse hook and turn drive pattern and positive and negative continuous rotation drive pattern.Forward and reverse hook turn drive pattern be make swing roller 4 be greater than 90 degree carry out with being less than the anglec of rotation alternate repetition of 180 degree forward hook rapidly turn and rapidly opposite arc rotate pattern.In addition, positive and negative continuous rotation drive pattern is following a kind of pattern: with the rotating speed making the deadweight of the washings be lifted by the rotation of swing roller 4 exceed the degree of the centrifugal force produced by the rotation of swing roller 4, forward and reverse continuous rotation alternately repeatedly carrying out swing roller 4.
In matting or matting and rinsing process, alternately perform forward and reverse hook and turn drive pattern and positive and negative continuous rotation drive pattern.When forward and reverse hook turns drive pattern, swing roller 4 is made to turn and suddenly brake being greater than the hook carried out rapidly in 90 degree of scopes being less than the anglec of rotation of 180 degree.Washings can be raised to thus and be greater than the anglec of rotation that 90 degree are less than 180 degree.In addition, suddenly braked by the terminal stage lifted at washings, can reliably complete following action: washings is peeled off from swing roller 4 inner surface due to its inertia and deadweight, falls and lift heterochiral side, side.Thus, fully to expand and the washings of the state of loose, easy cunning applies high to knead open effect especially to because being in containing washings.In addition, due to mechanical force can be applied to washings, therefore, it is possible to improve cleaning performance.Further, by alternate repetition carry out the positive direction of arc rotary actuation the hook of forward rapidly to turn and reciprocal opposite arc rapidly rotates, in each arc rotary actuation, can alternately change cocked position, the lowering position of washings in left and right.The effect of kneading open can be improved further thus while anti-entanglement of laundry.In addition, due to number of times washings being applied to mechanical force can be increased, therefore, it is possible to improve cleaning performance.In addition, by high kneading open that effect can suppress to carry out to clean, rinsing process and tangling between the washings that occurs.Thus, turn beating efficiently under drive pattern wash by performing forward and reverse hook continuously, cleaning performance and wash effect can be improved.
But only utilize forward and reverse hook to turn drive pattern, can alleviate on the one hand the tangling of washings, reverse, fold etc., the position being difficult to the above-below direction making washings is on the other hand changed, and is difficult to make the washings bottom swing roller 4 swing.Therefore, the cleaning that washings easily occurs is uneven, but can improve these problems by the positive and negative continuous rotation drive pattern of dual-purpose.That is, the replacing of the position of the above-below direction of washings can be realized by positive and negative continuous rotation drive pattern, the tangling of washings can be alleviated, reverse, fold.In addition, the mechanical force that washings is applied that forward and reverse hook turns under drive pattern can be alleviated unbalanced.That is, by using forward and reverse hook to turn drive pattern and these two kinds of patterns of positive and negative continuous rotation drive pattern, two kinds of different behaviors can be applied to the washings in cleaning, rinsing.Specifically, by forward and reverse hook turn drive pattern alleviating the tangling of washings, reverse, while fold, the behavior that reliable hand rubs cleaning applied to washings.On the other hand, by positive and negative continuous rotation drive pattern alleviating cleaning washings while the violent and continuous print of washings waves inequality, to the efficient cleaning behavior of washings applying for even and strong dirt.
Circulating pump 20 is fixed on platen 2a.The ejection side path 16b going out self-circulating pump 20 in water circulation path 16 towards tank 3 the second opening 13 at body of the washing machine 2 front extend.Specifically, as shown in Figure 2 A and 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 links.The circulating pump 20 formed by this way is inlaid in resinous mount pad 35.
Water circulation path 16 possesses: water guide road 55b, and washings flow through this water guide road 55b; Ejiction opening 55d, it is arranged on water guide road and sprays washings; And stream 52, it is connected with ejiction opening 55d, the washings sprayed is ejected in swing roller from ejiction opening 55d.As shown in Fig. 3 A, Fig. 3 B, be formed with bellying 3a in the latter half of the front bulkhead 3h of tank 3, this bellying 3a is roughly in Y-shaped, and the front side (outside, the nearby side in Fig. 3 A) to body of the washing machine bloats.The cover 55 of the shape that profile is roughly the same with bellying 3a is installed in the surface of the inner side of front surface wall 3h across sealing gasket 55a by the connection etc. of screw in the middle of the inner side of bellying 3a.Thus, water guide road 55b is formed by bellying 3a and cover 55.Thus, water guide road 55b be configured to towards the first opening 54 of swing roller 4 (be seen as left and right directions from body of the washing machine face side) in left-right direction extend.
The one end of the linking part 51 extended transversely 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.Thereby, it is possible to make washings flow in the 55b of water guide road from ejection side path 16b.
Cover 55 doubles as out the lid of the connection space 51a of the linking part 51 between the pipe arrangement (ejection side path 16b) of self-circulating pump 20 and water guide road 55b.Like this, by doubling as the lid of the connection space 51a of linking part 51 with cover 55, can easily solve by the factor in design, the position of linking part 51 of the constructional factor generation of metal die, the restriction of structure.
In addition, each upper end, left and right of the cover 55 roughly in Y-shaped is formed with the notch 55c not having hermetically-sealed construction as shown in Fig. 5 A, Fig. 5 B.Thus, between the back side (medial surface) of the front bulkhead 3h of notch 55c and the tank 3 corresponding with it, form the ejiction opening 55d of the opening had to circumferencial direction area extension.Ejiction opening 55d is configured respectively relative to such as the left direction side of drop wire and the end of right direction side: this vertical line is the vertical line of the installation surface at center relative to the first opening 54 through swing roller 4 in the 55b of water guide road.
Be recycled the washings that pump 20 pressurizes and flow into water guide road 55b via the ejection side path 16b of water circulation path 16 by linking part 51.The washings flowing into water guide road 55b be injected in by ejiction opening 55d the front bulkhead 3h of tank 3 the back side (medial surface) and and its position in opposite directions swing roller 4 front bulkhead 4b lateral surface between.Then, washings are ejected in swing roller 4 via stream 52, and this stream 52 is formed between the lateral surface of the back side (medial surface) of the front bulkhead 3h of tank 3 and the front bulkhead 4b of swing roller 4.
As shown in Figure 5A, ejiction opening 55d is towards the pivot direction of principal axis of swing roller 4, specifically towards jet 53 opening of the ring-type in stream 52.Thus, from ejiction opening 55d spray washings from stream 52 to the rotary middle spindle side of swing roller 4, the inner side rotary area being specifically radially ejected into swing roller 4 to jet 53 efficiently.Thereby, it is possible to independently provide washings efficiently with the number of washings.
Further, front bulkhead 3h possesses inclined plane 3h1, and this inclined plane 3h1 is from the position corresponding with ejiction opening 55d towards circumferential direction in washing machine, and the rear portion side to body of the washing machine 2 tilts.Also have guide surface 56, this guide surface 56 rolls tiltedly from the end of the inner side (right side Fig. 5 A) of the washing machine of this inclined plane 3h1 to the first opening 54 of swing roller 4 and extends.Thus, as shown in Figure 5A, the washings being ejected into stream 52 can be made from inclined plane 3h1 along guide surface 56, spray to the inner side of swing roller 4 from first opening 54 of jet 53 via swing roller 4.Thereby, it is possible to improve the efficiency providing washings to washings.
At this, as shown in Fig. 5 A, Fig. 5 B, be configured to arrange the different guide surface in inclination angle 56,57 respectively for multiple ejiction opening 55d.Such as, as shown in Figure 5A, the inclination angle that the guide surface 56 corresponding with the ejiction opening 55d (right side in Fig. 3 B) in left side is observed in front from the water guide road 55b branched out is set to α, in addition, as shown in Figure 5 B, the inclination angle that the guide surface 57 corresponding with the ejiction opening 55d (left side in Fig. 3 B) on right side is observed in front from water guide road 55b is set to β, and establishes α > β.The angle between inclined plane 3h1 and guide surface 56 or guide surface 57 is referred to respectively at this said inclination angle.By this structure, as shown in Figure 6, from front observe from the jet 53 in left side washings (arrow shown in Fig. 5 A a) as spray shape A spray to more top direction.On the other hand, from front, the washings (the arrow b shown in Fig. 5 B) observed from the jet 53 on right side spray to the below of spray shape A as spray shape B.That is, the washings ejected from each ejiction opening 55d guide surface 56,57 different along inclination angle flows, and is ejected in swing roller 4 from jet 53 via the first opening 54.Therefore, it is possible to realize the injection different relative to the rotary middle spindle spray angle of swing roller 4.
At this, the diffusion of the injection of above-mentioned inclination angle also in subtend swing roller 4 impacts.When inclination angle is little (such as when structure as shown in Figure 5 B), near angle changes from inclined plane 3h1 to guide surface 57, flow through along inclined plane 3h1 the washings come and sharply change at guide surface 57 upper angle.Therefore, the state that washings impact guide surface 57 is become.In this condition, occur to flow (such as to the arrow b direction flowing in Fig. 5 B) along the incline direction of guide surface 57, and to the flowing that circumferencial direction (direction along stream 52) spreads.Thus, become the injection with the washings that the circumferencial direction to washing machine spreads, namely, as shown in Figure 6, relative to the spray shape A of the washings that the inclination angle jet 53 from left side that is α sprays, inclination angle is that the spray shape B of the washings that the jet 53 from right side of β (as mentioned above, having the relation of α > β) sprays becomes the injection had to circumferencial direction diffusion.According to the result of the test of inventor, be about 120 degree to inclination angle, become the injection of washings large area diffusion, when inclination angle is more than 130 degree, become the membranaceous injection that diffusion is little.
