Specific embodiment

For the technical characterstic place that the present invention will be described in detail, hereby lifts following first embodiment and cooperate schema explanation such as Afterwards, in which:

As shown in Figures 1 to 4, a kind of water impeller 10 that a preferred embodiment of the present invention provides, it is mainly cyclic annular recessed by one Disk 11 and a mandrel 21 are formed, in which:

The recessed disk 11 of the ring-type, has a disk body 13 and a ringwall 15, which is protruded out upward by the periphery of the disk body 13.

The mandrel 21 divides into axle portion 23 and a lower shaft portion 25 on one, and axle portion 23 is located at the top of the disk body 13 on this, and To connect a drive shaft 100, on this, axle portion 23, which extends radially outwardly, multiple ribs 27, which passes through the disk body 13 And it is separated by a preset distance with the disk body 13, and be connected to the recessed disk 11 of the ring-type, multiple support by multiple ribs 27 The bottom of rib 27 is connected to the disk body 13, and the outer end of multiple ribs 27 connects the ringwall 15, axle portion 23 on this, multiple Multiple circulation roads 17 are formed between ribs 27 and the disk body 13；The lower shaft portion 25 is located at the lower section of the disk body 13, the lower axle Portion 25 forms a polygon cylinder 26, and in this present embodiment, which is triangulo column, the polygon cylinder 26 tool There is a bottom surface 263 of three side walls 261 and the corresponding polygon pole section, respectively the side wall 261 is connected to each of the bottom surface 263 Side, and the 261 adjoining border junction of side wall is chamfering and forms a long and narrow fillet surface 265 two-by-two, the respectively fillet surface 265 Upper end respectively corresponds the ribs 27, which reverses a predetermined angular with respect to the disk body 13, and makes the respectively side wall 261 and respectively the fillet surface 265 is oblique, and respectively the side wall 261 is in curved surface, respectively the fillet surface 265 is in being bent long and narrow extension Shape.Wherein, the direction of rotation when torsional direction of the bottom surface 263 is turned with the drive shaft 100 is identical, and the bottom surface 263 is turned round It is empty that the degree turned keeps the lower end of the fillet surface 265 not exceed another 265 upper end of fillet surface extends downward vertically one Quasi- vertical line L 1.By will each side wall 261 and respectively the fillet surface 265 is oblique, and respectively the side wall 261 is in curved surface, respectively should Fillet surface 265 is in the long and narrow technical characteristic for extending shape is bent, and first embodiment of the invention can be made in connection, and the drive shaft 100 uses When, water can up be stirred, and formed from lower to upper close to the water flow of the recessed disk 11 of the ring-type, be conducive to the recessed disk 11 of the ring-type and guide Water is discharged by the discharge outlet 98, effectively promotes the drainage efficiency of drain motor, and has effects that reduce noise.

In other embodiments, the respectively side wall 261 that water can up can be stirred and the respectively fillet surface 265 are only wanted, all It can be used as the aspect of the other implementations of the present invention, therefore, which can also wait for four side columns, five side columns ... (due to only It is variation in shape, therefore not separately with graphic representation), therefore the implementation kenel of the polygon cylinder 26 should not only be with the present embodiment Limit；And respectively the side wall 261 also can obliquely and be plane, respectively the fillet surface 265 is oblique and is the flat of long and narrow extension Face, it is same to have and water up be stirred, and formed from lower to upper close to the water flow of the recessed disk 11 of the ring-type, it is recessed to be conducive to the ring-type The effect of disk 11 guides water and is discharged by the discharge outlet 98, effectively promotes the drainage efficiency of drain motor, and reduces noise, because This, the respectively side wall 261 and respectively the implementation kenel of the fillet surface 265 should be not only limited with the present embodiment；Moreover, each fillet surface 265 upper end is not necessarily to correspond respectively to the ribs 27, also may be configured as the respectively fillet surface 265 difference of part The fillet surface 265 of the corresponding ribs 27 or whole does not correspond to multiple 27 (not shown) of ribs, therefore, respectively The each implementation kenel of the ribs 27 corresponding to the fillet surface 265, should be not only limited with the present embodiment.

Connect this, a kind of water impeller provided by the first embodiment of the present invention can up stir water, and formed by Under up close to the water flow of cyclic annular recessed disk, be conducive to cyclic annular recessed disk guiding water and be discharged by discharge outlet, effectively promote drain motor Drainage efficiency.

And a kind of water impeller provided by the first embodiment of the present invention, have effects that reduce noise.

The structure kenel of first embodiment of the invention described above connects the use shape for illustrating first embodiment of the invention State.

Please see Fig. 2 to Fig. 4, a kind of water impeller 10 of the invention, the catch basin 99 for being installed in a drain motor use, The top of the mandrel 21 is connected to the drive shaft 100, is turned due to the direction of rotation of the bottom surface 263 with the drive shaft 100 Direction of rotation is identical, and the 261 adjacent edge joint of side wall is chamfering and forms the fillet surface 265 two-by-two, and respectively side wall 261 It obliquely and is curved surface, and respectively the fillet surface 265 is oblique and to be bent long and narrow extension shape, therefore, when the drive shaft 100 When being turned, each side wall 261 and respectively the fillet surface 265 will drive the water (being depicted with arrows) in the catch basin 99 with each The side wall 261 and respectively the fillet surface 265 flows up, then (such as Fig. 4 is discharged by a discharge outlet 98 by multiple circulation road 17 It is shown)；In addition, each side wall 261 and respectively the fillet surface 265 is above-mentioned structure, when water repellent, is smaller to the resistance of water, can be with The generation of bubble is reduced, and then can reach the effect for reducing noise.

Accordingly, by means of it can be seen from the above, the first embodiment of the present invention can be incited somebody to action by the structure of each side wall and each fillet surface Water is up stirred, and is formed from lower to upper close to the water flow of cyclic annular recessed disk, is conducive to cyclic annular recessed disk guiding water and is discharged by discharge outlet, Effectively promote the drainage efficiency of drain motor.

And the present invention can have effects that reduce noise by the structure of each side wall and each fillet surface.

Then, referring to Fig. 5, a kind of water impeller 10 ' provided by the second embodiment of the present invention, before being mainly generally same as First embodiment, the difference is that:

The lower shaft portion 25 ' have multiple fins 29 ', respectively the fin 29 ' along and the respectively fillet surface 265 ' is completely covered, and Respectively the end of the fin 29 ' is formed with a rounded corner 291 ', and respectively the fin 29 ' is by the respectively rounded corner 291 ' and the bottom surface 263 ' Each angle be connected.

Remaining structure of this second embodiment and the effect of capable of reaching, take off first embodiment before being generally same as, and Rong Buzai gives It repeats.

Certainly, the present invention can also have other various embodiments, without deviating from the spirit and substance of the present invention, ripe Various corresponding changes and modifications, but these corresponding changes and modifications can be made according to the present invention by knowing those skilled in the art It all should belong to the protection scope of the claims in the present invention.
