Watering path 34 has when direction of principal axis is overlooked for circular cylindrical portion 34b.In cylindrical portion The side face of 34b is formed and connects with circulation waterway 37 and import the water inlet 34c of washings.Should Water inlet 34c is configured to washings and imports from the substantially tangent line S direction of cylindrical portion 34b.As this Sample, by importing washings, Neng Gou from substantially tangential direction S of the side face of cylindrical portion 34b Washings are made to produce rotational flow (reference arrow) in cylindrical portion 34b, can be with from outlet 34a Spray washings to the mode that radial outside significantly extends.

Fig. 8 is the Section A-A figure of Fig. 7.

As shown in Figure 8, cylindrical portion 34b has: produce the rotating room 34b1 of rotational flow；To Axle central horizontal highlights and at circumferentially extending flank 34d；With in the lower section of flank 34d with Remove the wide diameter portion 34e (flowing path section expansion section) of enlarged-diameter to outlet 34a.This wide diameter portion 34e is configured to flow path cross sectional area and becomes big with going to outlet 34a.

Flank 34d have the rotational flow of the washings making to import from water inlet 34c to radially Power F1 and power F2 below vertical in power F2 reduce, make from outlet 34a to The function that the water yield of the washings (axially) spraying below vertical reduces.

In addition, flank 34d is not to arrange throughout complete cycle, but have not in a circumferential part The 34d1 without flank of flank 34d is set.Thereby, it is possible to prevent water from accumulating on flank 34d, It is prevented from for example washing and terminate rear water (water droplet) and drop to washings from outlet 34a.

This wide diameter portion 34e is configured to the lower section flow path cross sectional area at flank 34d to outlet 34a Become larger.That is, the internal face of the wide diameter portion 34e of present embodiment has curvature R3, R4. In addition, the curvature of the internal face of wide diameter portion 34e is not certain, it is also possible to outlet 34a (opening edge) gradually expands curvature.

In addition, wide diameter portion 34e is formed as relative to the some P1 linking flank 34d side and outlet The point P2 of 34a side and the straight line L that formed, to the convex that the axle central side of cylindrical portion 34b is protruding Shape (swells shape, chevron).In addition, wide diameter portion 34e is configured to the tangential direction at a P2 Direction be radially oriented outside.

In addition, curvature R3 in the left and right of the outlet 34a shown in the cross section of Fig. 8 and curvature R4 is set as same degree.

In addition, in present embodiment, there is curvature R3, R4 to be formed with at wide diameter portion 34e Face in case of be illustrated but it also may be not wide diameter portion formed there is curvature The structure (for example, circular cone trapezoidal shape) in face.

As it is shown in figure 9, be positioned at the wide diameter portion 34e of front side with the curvature more than curvature R3, R4 R1 is formed.In addition, be positioned at the wide diameter portion 34e of rear side with curvature R2 less than curvature R3, R4 Formed.Like this, from watering path 34 to washing and dewatering cylinder 9 internal perisporium distance relatively In the case of long, curvature R1 forms greatly, in the case that this distance is shorter, and curvature R2 shape Cheng get little.In addition, the angle (scope) that curvature can be specified by each periodically changes, Also can change continuously.

Have in the washing machine 100 of watering path 34 of so composition, lead from circulation waterway 37 Entering the washings to watering path 34 (cylindrical portion 34b), spiral rotating is while at cylinder To vertical flowing underneath in portion 34b.Now, the downstream in cylindrical portion 34b is provided with Flank 34d, it is possible to expand the spraying range (watering scope) from outlet 34a ejection. This is because, the part current flowing in downward direction at flank 34d is rectified into radial direction Flowing.

In addition, by the expansion arranging curvature R1, R2, R3, R4 in the downstream of flank 34d Footpath portion 34e, can make current radially accelerated (concentration), can expand spraying range further (watering scope).In addition, utilize the surface tension that the material constituting watering path 34 is had Also can tractive water, therefore, it is possible to expand spraying range (watering scope).

Here, the dimensional parameters and flow of watering path 34 (cylindrical portion 34b) is expanded with sprinkling The relation of the situation of exhibition illustrates.As shown in Figure 8, if the thickness of flank 34d is " a ", The internal diameter of flank 34d is " b ", and the internal diameter of rotating room 34b1 is " c ", from flank 34d Surface is to a length of " d " of the starting point of curvature.

In this case, the more little then spraying range of thickness a (watering scope) is bigger, thickness a More big then spraying range (watering scope) is less.Internal diameter b is to determine spraying range and spray flow The important parameter of amount, the big then spraying range of internal diameter b is little and to spray flow many, otherwise, internal diameter b Little, it is little that spraying range sprays flow greatly, therefore preferably determines size according to purposes.Length d It is the important parameter determining spraying range, be preferably (c-b)/less than 2.Curvature R is to determine spray Spill the most important parameters of scope, preferably ensure that curvature R big as far as possible in structure.

Figure 10 is the schematic diagram representing water-injection mode corresponding with the amount of washings.

From the water of circulation waterway 37, become from water inlet 34c along the side of rotating room 34b1 The rotational flow (with reference to Fig. 8) that wall (inner circumferential wall) is flowed in watering path 34, from discharge Mouth 34a is ejected in washing and dewatering cylinder 9.

As shown in Figure 10, the centrifugal action of rotation is in rotating room 34b1 (with reference to Fig. 8) Water, therefore rotates downwards substantially from outlet 34a (with reference to Fig. 8) water out The diffusion in a thin film of cone, spreads on washings.

In addition, watering path 34 is positioned at from the center of washing and dewatering cylinder 9 to inboard (Figure 10 Rear side) position that offsets.Therefore, the ejection water from outlet 34a (with reference to Fig. 8), When the amount of washings is few throughout substantially washings entirety, but as the amount of washings increases, wash Washing the upper surface of thing near outlet 34a (watering path 34), therefore washings are difficult to spread to It is positioned at the washings (with reference to Figure 10) of the front side (front side) of washing and dewatering cylinder 9.But, By arranging the wide diameter portion 34e of curvature R1 at outlet 34a (spraying outlet), can expand Spraying range (watering scope), even if the amount increase of washings also can be overall uniformly to washings Ground spreads washings.In addition, in general outlet 34a must be made in order to expand spraying range Flow path cross sectional area formed less, but in present embodiment, utilize the centrifugal force rotating, and And the wide diameter portion 34e expanding flow path cross sectional area to outlet 34a is set, it is possible to not reduce row The area ground of outlet 34a expands spraying range (watering scope), can spray washings fully Spill to the front side of washing and dewatering cylinder 9.Further, since do not reduce the stream of outlet 34a Sectional area (does not needs to reduce stream), so also having little excellent of possibility that line bits blocking occurs Point.

And, according to the watering path 34, rated capacity 10kg that apply present embodiment Washing machine (scrubbing-and-drying unit) washing test (Japanese Industrial Standards: household electricity do washing The scourability of the performance measurement method JIS C9811-1999 of machine) result, in the feelings of 10kg Under condition, cleaning rate improves about 2%, cleans inequality and reduces about 2%.Confirm and more do not allow at washings The minimizing that in the case of specified (10kg) of easy activity, washing is uneven is notable, and washings is equal The definite effect of even distribution.

Figure 11 is the schematic diagram representing watering scope.

Owing to arranging the relation of washings input port 10a1, it is impossible to will watering path 34 (outlet 34a) configuration is at the pivot O of washing and dewatering cylinder 9, therefore (discharges watering path 34 Mouth 34a) it is set in the position more more rearward than pivot O.In addition, make spraying range (spill Water scope) 360 degree uniform when, be also determined from the water yield of watering path 34 ejection, therefore to Splash with the water in the direction of the distance of watering path 34 and diminish.Then, in present embodiment, As described above, the location bias of watering path 34 is in the rear of pivot O, from watering path The distance of 34 to internal perisporium is uneven, in this case, by according to watering path 34 and washing The distance of the internal perisporium (main board) of double dehydration tube 9 changes the curvature of wide diameter portion 34e, can Change spraying range (watering scope).

As shown in figure 11, relative to watering path 34, the distance in front is the longest, therefore by making Curvature R1 (with reference to Fig. 9) of wide diameter portion 34e is maximum, can expand watering scope Q1.In addition, Relative to watering path 34, the distance at rear is the shortest, therefore by making the curvature of wide diameter portion 34e R2 (with reference to Fig. 9) is minimum, can reduce watering scope Q2.In addition, relative to watering path 34, the distance of left and right is in intermediate degree, therefore by making curvature R3, the R4 of wide diameter portion 34e (with reference to Fig. 8) is the intermediate curvature of curvature R1 and curvature R2, can make watering scope Q3, Q4 is in the scope of the centre with watering scope Q2 for watering scope Q1.

Like this, when determining from watering path 34 water yield out, water-out manners 360 degree is made If Jun Yun, then the splashing of water is little, but as described above, by according to from watering path 34 away from From changing water-out manners, make while the water yield can not be changed washings reach in 360 degree of complete cycles and wash Wash the perisporium (main board) of double dehydration tube 9.
