Detailed Description
The technical scheme of the invention is further explained by the specific implementation mode in combination with the attached drawings.
The invention provides a washing machine with an impeller convenient to disassemble, which comprises an impeller 1 and an output shaft 2, wherein the output shaft 2 penetrates through the impeller 1 and drives the impeller 1 to rotate, specifically, the impeller 1 and the output shaft 2 are connected through an insert 5, and the impeller 1 can rotate along with the output shaft 2 through the insert 5.
In this embodiment, the output shaft 2 passes through the impeller 1, and one end of the output shaft is detachably connected with an impeller fastening cover 3, specifically, the output shaft 2 is in threaded connection with the impeller fastening cover 3, and one end of the impeller fastening cover 3 abuts against the impeller 1, so as to fix the impeller 1 on the output shaft 2 and limit the axial movement of the impeller 1. Specifically, referring to fig. 1, the pulsator fastening cover 3 has a cylindrical structure, a stepped hole 31 is formed at a middle portion thereof, one end of the stepped hole 31 having a small diameter is located at an upper end portion of the pulsator fastening cover 3, one end of the stepped hole 31 is threadedly coupled to the output shaft 2, the pulsator fastening cover 3 is fixedly coupled to the output shaft 2 by means of a threaded coupling between the stepped hole 31 and the output shaft 2, and axial movement of the pulsator 1 is restricted. In this embodiment, the end of the stepped hole 31 that is screwed to the output shaft 2 may be the end with a smaller diameter, and the end with a smaller diameter of the stepped hole 31 is screwed to the end of the output shaft 2 that passes through the pulsator 1. The end of the stepped hole 31 screwed with the output shaft 2 may also be an end with a large aperture, and the end with the large aperture of the stepped hole 31 is screwed with the lower end of the output shaft 2 penetrating through the pulsator 1 (i.e. the end of the output shaft 2 penetrating through the pulsator 1 and close to the pulsator 1).
A rotary cover 4 is sleeved outside the impeller fastening cover 3, the rotary cover 4 can move up and down relative to the impeller fastening cover 3, and the rotary cover 4 selectively cooperates with the impeller fastening cover 3 to lock and unlock the impeller 1 and the output shaft 2. Specifically, when the rotary cover 4 moves, the impeller fastening cover 3 is clamped, and the impeller fastening cover 3 can be screwed after the impeller fastening cover 3 is clamped. Through revolving spiral cover 4 soon, and then revolve revolving impeller fastening cover 3 by spiral cover 4 drive, can make impeller fastening cover 3 lock or break away from output shaft 2, and then can get off impeller 1 installation or dismantlement. In this embodiment, when the end of the stepped hole 31 screwed to the output shaft 2 is the end with a small diameter, the screw cap 4 needs to be moved upward, and at this time, the screw cap 4 tightly clamps the pulsator fastening cap 3 and can screw the pulsator fastening cap 3. When the one end of shoulder hole 31 and output shaft 2 threaded connection is the one end that the aperture is big, need move spiral cover 4 downwards, spiral cover 4 chucking impeller fastening cover 3 and can twist impeller fastening cover 3 soon this moment.
In this embodiment, referring to fig. 1 and 2, one end of the rotary cover 4 close to the impeller 1 is provided with a hole groove 41, specifically, the hole groove 41 is provided at the middle position of the rotary cover 4, the impeller fastening cover 3 is located in the hole groove 41 and is adapted to the shape of the hole groove 41, a clamping part 42 made of flexible material circumferentially extends on the inner wall of the hole groove 41 along the direction pointing to the axis thereof, the outer wall of the impeller fastening cover 3 is provided with a groove 32 circumferentially arranged, when the rotary cover 4 is not moved, the clamping part 42 is partially located in the groove 32, and the length of the clamping part 42 located in the groove 32 is the depth of the groove 32
When the locking part 42 is not moved, a certain limit effect can be achieved by the part located in the groove 32. When the chucking part 42 is moved upward or downward, the portion of the chucking part 42 located in the groove 32 is separated from the groove 32 by an external force and moved to the outer wall of the pulsator fastening cover 3 located at the upper or lower side of the groove 32, and the portion thereof located in the groove 32 is pressed due to the flexible property of the chucking part 42, and thus, the pulsator fastening cover 3 is chucked.
Preferably, an arc-shaped surface is arranged on one side of the clamping part 42, which is opposite to the fastening cover 3 of the pulsator, and when the screw cap 4 moves, the clamping part 42 transits to move to one end of the fastening cover 3 of the pulsator and the output shaft 2 in threaded connection through the arc-shaped surface. That is, by providing the arc-shaped surface, the clamping part 42 is more smoothly moved to the outer wall of the pulsator fastening cover 3 on the upper side or the lower side of the groove 32.
