On the other hand, dehydration basket 12 is rotatably configured with in the inside of drench pit 3.Multiple dewatering hole 12a is formed at all sidepieces of dehydration basket 12.Below outside drench pit 3 is configured with dehydration motor 13 and brake apparatus 14.Dehydration motor 13 can rotary actuation dehydration basket 12.Brake apparatus 14 can prevent this rotation.Dehydration basket 12 is by dehydration motor 13 directly rotary actuation.Specifically, dehydration basket 12 is toward the direction by rotary actuation at high speed, and the washings that will be housed in dehydration basket 12 by this rotation is dewatered.Therefore, dehydration motor 13 as rotary actuation dehydration basket 12 drive unit and play its function.Water discharge outlet 15 is formed in the bottom of drench pit 3.This water discharge outlet 15 connects described scupper hose by not shown interflow pipeline.
Outer container 1 is provided with guidance panel 16.This guidance panel 16 is provided with operation knob 17 and slurry intensity of flow switch knob 18, the operation knob 19 of dehydration timer, the operation knob 20 of opening and closing of drain valve, the water supply hose connector 21 of washing timer.Sink 2 is provided with the lid 22 of sink removably.Drench pit 3 can be supported with opening and closing the lid 23 of drench pit by bearing.
Below, the detailed setting of this impeller 4 is described.As shown in Figure 1 to Figure 3, impeller 4 is become by plastics.The flat shape of impeller 4 is circular.The seat surface 4a of impeller 4 is formed as the general planar shape of slightly swelling gradually towards the peripheral direction of seat surface 4a.On impeller 4, by being formed with multiple recess 4b for benchmark from the mode that seat surface 4a is recessed with the described seat surface 4a of general planar.Multiple recess 4b are arranged in the circumferencial direction of impeller 4 equably.These recesses 4b all spherically shape.The blade convex tendon 4c as protuberance is provided with in the mode that (direction substantially vertical with described seat surface) is outstanding respectively upward from the bottom surface inside each recess 4b.Each blade convex tendon 4c gives prominence to from the described bottom surface of described inner side in the scope of each recess 4b, and the central portion being present in each recess 4b is on the intimate whole diameter length of its direction of both ends.
From top (direction substantially vertical with described seat surface) top view, each blade convex tendon 4c is Radiometric profiles shape.This Radiometric profiles is formed bending near the central portion of impeller 4 to lateral direction, bend toward the clockwise direction in FIG.Further, as shown in Fig. 4 and Fig. 1, be positioned at the both sides face 4c of the blade convex tendon 4c of the direction of rotation of impeller 4
1, 4c
2inclined angle alpha, β roughly equal.In addition, as shown in Fig. 5 and Fig. 1, the side surface part 4c of each blade convex tendon 4c central side
3inclination angle γ and the side surface part 4c of each blade convex tendon 4c outer circumferential side
4tiltangleθ not identical, and the side surface part 4c of described central side
3inclination angle γ be set to the side surface part 4c being greater than outer circumferential side
4tiltangleθ.
As shown in Figure 1 to Figure 3, be provided with and blade convex tendon 4c disjunct independently jut 4d at the central portion of impeller 4.This jut 4d is in roughly semi-spherical shape.More particularly, jut 4d is formed by with impeller 4 parts independently, and by multiple claw 4d
1be arranged on the central portion of impeller 4.As shown in Figure 1 to Figure 3, in the outer surface portion of this jut 4d, be formed with the low-lying portion 4e of multiple round shape in the mode of the circumferencial direction being arranged in described impeller equably.
Being positioned at the lowermost portion of recess 4b of each blade convex tendon 4c both sides, be respectively formed with multiple osculum 4f.As shown in Figure 3, porose 4g is formed at the central part of jut 4d.Hole 4g is inserted by screw 7, and screw 7 combines with the output shaft 6a of transmission mechanism 6.Hole 4g cover 4h blocking.
Like this, washings can be housed in the inside of sink 2 by above-mentioned washing machine together with washings.In this state, by rotary actuation impeller 4, described washings is stirred washing together with described washings.In described impeller 4, by from the recessed mode of this seat surface 4a, being formed with multiple recess 4b at the circumferencial direction of described impeller for benchmark with the seat surface 4a of general planar.Blade convex tendon 4c is provided with in the mode of giving prominence to upward from the bottom surface inside each recess 4b.
As shown in Figure 7, due to the actual basic point of each blade convex tendon 4c be lower than each recess 4b of seat surface inside bottom surface, therefore the height H 1 of multiple blade convex tendon 4c of impeller 4 becomes higher.In the figure 7, washings W enters in recess 4b.Therefore, when impeller 4 is rotated by the direction shown in arrow X or Y in Fig. 7, based on multiple blade convex tendon 4c of high height (larger area), described washings W is subject to powerful mixing power and is stirred, and consequently generates strong current.To be stirred along with this strong current due to described washings and cleaned by brute force, therefore, it is possible to obtain high cleaning strength.
On the other hand, as shown in Figure 8, when washings S is lower than washings mobility, washings S slides on smooth seat surface 4a, touches multiple blade convex tendon 4c and is absorbed in hardly in multiple recess 4b.Therefore, because the contact of these blade convex tendon 4c and washings S is limited at height (area) H from the initial blade convex tendon 4c of the seat surface 4a of impeller 4
2in, so washings S can not be subject to so powerful mixing power.Its result, in sink 2, when the capacity relative to sink 2 contains a large amount of washings of almost fully loaded degree, can avoid causing the rotation of impeller 4 restrained (locking) by this washings.Contain the situation of a small amount of washings in swivelling chute 2 under, washings leaves impeller 4 and floats, the less mixing power be directly subject to from multiple blade convex tendon 4c.Therefore, the powerful current generated by foregoing strong stirring washings like that, washings will be cleaned by brute force.
In above-mentioned washing machine, multiple blade convex tendon 4c of impeller 4 are only outstanding from the bottom surface inside recess 4b separately.Therefore, be set to necessary bottom line by the area covered by blade convex tendon 4c, can more efficiently obtain above-mentioned clean result.
Further, in the washing machine of said structure, impeller 4 rotates towards positive and negative both direction.Multiple blade convex tendon 4c of impeller 4 are at the both sides of direction of rotation face 4c
1, 4c
2inclined angle alpha, β roughly equal.Based on such setting, impeller 4 can obtain equal mixing power towards the rotation of positive and negative both direction, thus can prevent clean uneven.
In above-mentioned washing machine, the side surface part 4c of each blade convex tendon 4c central side of impeller 4
3inclination angle γ and the side surface part 4c of each blade convex tendon 4c outer circumferential side
4tiltangleθ not identical.Specifically, inclination angle γ is set to and is greater than tiltangleθ, based on such setting, the described side surface part 4c larger at inclination angle
3washings can be made easily to shift to outer circumferential side, and the described side surface part 4c less at inclination angle
4washings can be made to be difficult to shift to outer circumferential side.Like this, washings can be made to rest near certain position and carry out stirring and cleaning, thus acquisition what is called rubs the effect of washing.
As mentioned above, in above-mentioned washing machine, impeller 4 rotates towards positive and negative both direction.Further, multiple blade convex tendon 4c of impeller 4 be formed as from top view be Radiometric profiles shape.Based on such formation, in the outside of this curve (bending), the direction (in FIG for counterclockwise) pointed to towards this Curves by impeller 4 is rotated, produce the force that thruster outwardly spendes washings, and produce following effect, even if namely will occur that the curling winding of washings also can remove this winding.In contrast, in the inner side of described curve (bending), the direction (being clockwise direction in FIG) pointed to towards this Curves by impeller 4 is rotated, and produces the power inwards pulling washings.Based on the power of these two strands of different directions toward the outer side and towards inner side, washings is prevented by push-and-pull to be wound around, and is extruded washing simultaneously.Based on such function, can obtain only by stirring the high cleaning strength that cannot obtain.
In above-mentioned washing machine, have and multiple blade convex tendon 4c disjunct independently jut 4d at the central portion of impeller 4.The peripheral speed of described jut 4d when impeller 4 rotates is less.On the other hand, be present in and more lean on the peripheral speed of multiple blade convex tendon 4c when impeller 4 rotates of the outer circumferential side of impeller 4 larger than described jut 4d.Be present in and more by multiple blade convex tendon 4c of outer circumferential side of impeller 4, there is the mixing power to washings and washings than jut 4d.On the other hand, the jut 4d being present in the central portion of impeller 4 has the mixing power to washings and washings hardly.Based on such structure, when impeller 4 rotates, because washings is screwed, rubs and wash, therefore, it is possible to obtain higher cleaning strength based on this between jut 4d and multiple blade convex tendon 4c.
In addition, in above-mentioned washing machine, in the outer surface portion of the above-mentioned jut 4d of impeller 4, there is multiple low-lying portion 4e.Based on such structure, when impeller 4 rotates, due to washings can be washed by rubbing with the hands, therefore, it is possible to obtain high cleaning strength based on this at the peripheral part of multiple low-lying portion 4e.
Described washing machine can not have dehydrating function.The described structure of described washing machine also can be applied to be had in concentric sink and the Dewaterring and washing machine (automatic washing machine) of dehydration basket.
