Detailed Description

The invention is described in further detail below with reference to the accompanying examples.

Example 1

As shown in fig. 1 to 3, the present invention provides a pulsator washing machine including a cabinet 1, a cover 2, a washing tub 5, a pulsator 7, an upper pulsator 4, a hollow motor 3, a connection lever 82, and an inclined lever 81.

Wherein, a washing tub 5 is arranged in the machine shell 1, a wave wheel 7 is arranged in the washing tub 5, a driving motor 8 is arranged below the washing tub 5, a supporting platform 51 is upwards formed at the bottom of the washing tub 5, an arc-shaped concave cavity is formed at the top of the supporting platform 51, a ball head 6 is formed at the middle part of the wave wheel 7, the ball head 6 is in ball hinge joint in the arc-shaped concave cavity, a through hole 511 communicated with the arc-shaped concave cavity is arranged on the supporting platform 51, the bottom of the ball head 6 is connected with an inclined connecting rod 82, the output end of the driving motor 8 is connected with an inclined rod 81 in an inclined way, the lower end of the connecting rod 82 is rotatably connected above the inclined rod 81, the cover 2 covers the top of the machine shell 1, a fixing rod 21 penetrating through the washing tub 5 is arranged in the middle of the cover 2, a limiting block 211 is arranged at the lower end of the fixing rod 21, and an arc-shaped groove attached to the ball head 6 is formed in the lower side surface of the limiting block 211.

Further, a hollow motor 3 is provided on the cover 2, a hollow shaft of the hollow motor 3 is inserted into the fixing rod 21, and an upper pulsator 4 or a stirring blade 31 arranged along the length direction of the hollow shaft is provided on the hollow shaft. The washing machine has the advantages that the double-impeller washing or stirring washing function of the washing machine is realized by additionally arranging the impeller 4 structure or the stirring blade 31 structure in the washing tub 5, and the washing capacity of clothes is improved.

In addition, in order to further strengthen the rolling motion of the impeller 7, reduce the water current vortex phenomenon that the impeller 7 produced, it has a gag lever post 71 to extend on the impeller 7 outer wall, spacing groove 501 has vertically been seted up on the inside wall of pail 5, gag lever post 71 is spacing in spacing groove 501, through setting up gag lever post 71 and spacing groove 501 structure, the rotation of impeller 7 receives the restriction, make the impeller 7 can only do the motion of turning from top to bottom, the laundry in-process, the rotatory vortex effect of rivers has been reduced, the effect of stirring of rivers has been improved, the realization that rolls that utilizes rivers washs the clothing, avoided the laundry to take place the winding because of the reverse rotation motion.

In addition, the below of pail 5 sets up the return water tank, and the return water tank is connected in the through-hole department of pail 5 outer wall, and the bottom of return water tank is connected with the connecting pipe with pail 5 intercommunication, and in the rivers that leak that arouse because of sealed not enough flow back to the return water tank, reentrant pail 5 by the return water tank again.

When the laundry is washed, first, the lid 2 is opened to put the laundry into the washing tub 5, and at the same time, the washing tub 5 is filled with clean water and detergent, and then the cover 2 is closed, and during the process that the cover 2 is closed to the cabinet 1, a limit block 211 at the bottom of a fixed rod 21 on the machine cover 2 just props against the bulb 6 of the wave wheel 7, so that the ball head 6 is limited in the arc-shaped groove of the limiting block 211 and the arc-shaped concave cavity of the supporting table 51, the ball head 6 can move in a spherical hinge in the arc-shaped concave cavity, and then, the driving motor 8 works, the driving motor 8 drives the impeller 7 to rotate through the bulb 6, or the pulsator 7 is swung up and down, so that the effect of water flow eddy generated by the movement of the pulsator 7 in the washing tub 5 is weakened, meanwhile, the tumbling motion of water flow is enhanced, so that the phenomenon of clothes winding in the washing process is effectively relieved. Further, in order to improve the cleaning capacity, the hollow motor 3 can synchronously work along with the driving motor 8 in the washing process, so that the upper impeller 4 also rotates, and the washing machine is changed into a double-impeller cleaning structure, thereby improving the cleaning capacity and the cleaning efficiency of the washing machine on clothes.
