In addition, provide a kind of guide mechanism that is used to guide reciprocating member 400 up-and-down movements of the present invention.
Guide mechanism comprises a plurality of hollow circular cylinders 500 that are fixed in the rotating cylinder internal perisporium.Each reciprocating member 400 all is slidably inserted in each hollow circular cylinder 500.Under the preferable case, according to a preferred embodiment of the invention, the number of hollow circular cylinder 500 is identical with the number of reciprocating member 400.Hollow circular cylinder 500 guiding reciprocating members 400 when reciprocating member 400 moves up and down.The inside diameter of each hollow circular cylinder 500 is all greater than the diameter of each reciprocating member 400, and is formed with the hole 510 identical with each reciprocating member 400 diameter, an aperture in the top, so that the top of each reciprocating member 400 is therefrom passed.
Each hollow circular cylinder 500 all is being formed with a vertical elongated slot 520 on the sidewall of rotating cylinder 220 central parts.The boss 430 of each reciprocating member 400 all stretches out a predetermined length from vertical elongated slot 520.Thereby vertical elongated slot 520 has a predetermined length is in vertical reciprocating motion boss 430 when impeller 300 rotations.
According to a preferred embodiment of the invention, stage clip 600 inserts respectively in the hollow circular cylinder 500.The upper end of each stage clip 600 all is fixed to the upper end of each hollow circular cylinder 500, and its lower end is bearing on the upper surface of first diskware 420 of each reciprocating member 400, thereby pushes away reciprocating member 400 downwards.
According to a preferred embodiment of the invention, reciprocating member 400 integrally is formed with one second diskware 440 in the top, the diameter of second diskware 440 is greater than the diameter of reciprocating member 400, thereby applies and upward pressure being loaded on laundry water in the rotating cylinder 220 when reciprocating member 400 motions.
On the other hand, impeller 300 surface thereon is formed with a plurality of radial blades 320 highlightedly, and is formed with a plurality of holes 310 of vertically passing impeller.
Below, the present invention has the operation of the washing machine 200 of vertical reciprocating member 400 with reference to description of drawings.
When laundry water infeeded rotating cylinder 220, motor 230 was actuated to begin the washing operation.Power transmission 240 is accepted by the revolving force of motor 230 generations and to second rotating shaft 260 by belt 250 and is transmitted a rotating speed that reduces to rotate impeller 300.Because impeller 300 connects second rotating shaft 260 obliquely, it will vertically vibrate.As shown in Figure 5, when impeller 300 rotations, boss 430 reciprocating motion vertically of reciprocating member 400.At this moment, the upper surface that is formed at first diskware 420 of each reciprocating member 400 is pushed downwards by stage clip 600, thereby makes each boss 430 contact the upper surface of impeller 300 all the time.When each reciprocating member 400 was in vertical reciprocating motion, each boss 430 moved along the elongated slot 520 that is formed at each hollow circular cylinder 500.
Therefore, when impeller 300 rotations, reciprocating member 400 is in vertical reciprocating motion continuously with the vibration of impeller 300.At this moment, second diskware 440 upwards pumps the laundry water around diskware, thereby produces vertical lifting stream.
Simultaneously, by being formed at the blade 320 of impeller 300 upper surfaces, in rotating cylinder 220, produce eddy current.In addition, laundry water passes the hole 310 that is formed at impeller 300, thereby produces fluid upwards.Correspondingly, the upwards fluid that produces to reciprocating member 400 mixes with eddy current, thereby produces complicated turbulent flow in rotating cylinder 220, has therefore prevented the winding of clothing and has improved the efficient of washing.
As mentioned above, the washing machine with vertical reciprocating member according to the present invention can make progress in rotating cylinder and spray laundry water, thereby produces complicated turbulent flow in rotating cylinder, has therefore improved its detersive efficiency.
Although described the preferred embodiments of the present invention, should be understood that the present invention is not limited to the preferred embodiment, those skilled in the art carries out various changes and modifications in the spirit and scope of the present invention for required protection below.
