The present invention will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.
The present invention provides a laundry device comprising a washing tub 11 and a pulsator 10 rotatably installed in the washing tub 11, a space S at the lower side of the impeller is formed between the impeller 10 and the bottom of the washing barrel 11, a through hole is formed at the center of the impeller 10, a drain hole 111 is formed at the center of the bottom of the washing tub 11, the laundry appliance further includes a filter housing 20, the filter cap 20 covers the through hole and has an upwardly convex shape, the filter cap 20 includes a first through-flow portion 202 at the top and a second through-flow portion 201 at the side wall, the inner wall of the filter cover 20 is provided with a flock filter net covering the first through-flow part 202, the filter cover 20 is provided with a one-way sheet 204 inside to cover the second through-flow portion 201, the one-way sheet 204 is arranged to be capable of being turned and opened at a certain angle towards the inside of the filter housing 20 under the action of an external force; a filter grid 101 is disposed in the space S under the pulsator around the through holes and the drain holes 111, and a lint filter screen is covered on the filter grid 101 to separate the space S under the pulsator into a lint containing part C at the center.
When the washing machine of the present invention is used, during the washing process, the pulsator 10 rotates, the washing water containing the hair debris in the washing tub 11 makes a circular motion under the action of the pulsator 10, and simultaneously the water flow below the pulsator 10 is subjected to a centrifugal force and is diffused towards the edges under the action of the drainage structure at the bottom of the pulsator 10, so that a certain negative pressure is formed below the center of the pulsator 10, the pressure above the pulsator 10 is greater than the pressure below the pulsator 10, the pressure difference existing between the upper side and the lower side of the pulsator 10 causes the water flow in the washing tub 11 to flow into the space S below the pulsator 10 through the filter cover 20 and finally return to the washing tub 11 through the backflow structure at the periphery of the pulsator 10, and when the washing water containing the hair debris in the washing tub 11 passes through the filter cover 20, a force directed towards the inside of the filter cover 20 is applied to the one-way sheet 204 at the inner side wall of the filter cover 20, and under the action of the force, the one-way sheet 204 is turned and opened at a certain angle toward the inside of the filter housing 20, so that the washing water and the lint therein can enter the filter housing 20 through the second through-flow portion 201 and finally reach the space S at the lower side of the pulsator through the through-holes, but due to the presence of the lint filter screen on the filter grid 101, the lint cannot finally continue to pass through the filter grid 101 and return to the washing tub 11, but remains in the filter housing 20 or the lint containing portion C; when the rotation of the pulsator 10 is stopped at the end of washing, the pressure difference existing between the upper side and the lower side of the pulsator 10 disappears, an upwelling water current is formed in the center of the pulsator 10, that is, the water current flows upward from the space S under the pulsator through the through holes and the filter housing 20 into the washing tub 11, the check sheet 204 is forced toward the outside of the filter housing 20 to return to a position covering the second through-flow portion 201 by the impact of the upwelling water current, the second through-flow portion 201 is closed, the upwelling water current flows into the washing tub 11 through the first through-flow portion 202, and the lint cannot flow through the first through-flow portion 202 due to the existence of the lint filter screen covering the first through-flow portion 202 but remains in the filter housing 20 or the lint receiving portion C, so that the washing apparatus of the present invention can perform washing process and washing end moment, the lint in the washing tub 11 is automatically received and retained in the lint receiving chamber formed by the filter housing 20 and the lint receiving portion C. During the drainage process, the water flow passes through the first through-flow part 202 and the second through-flow part 201 of the filter cover 20, enters the filter cover 20, continues to pass through the through hole in the center of the pulsator 10 and the space S under the pulsator, and finally is discharged from the water discharge hole 111 at the bottom of the washing tub 11, and during the process, the flock collected and accumulated in the filter cover 20 and the flock containing part C is discharged from the water discharge hole 111 along with the water flow, so that the automatic discharge of the flock is realized.
In conclusion, the washing equipment provided by the invention realizes automatic collection and discharge of the lint in the normal working action of the washing equipment such as washing and drainage, the user does not need to manually remove the lint, the lint does not accumulate frequently to cause bacterial breeding, and the user experience is good and the washing equipment is cleaner and more sanitary; in addition, the water flow path of the washing device during operation (during washing and draining) is fully considered, the collected lint is effectively prevented from flowing back, the lint collecting effect is improved, and the lint is collected at the center of the pulsator 10 and corresponds to the position of the drain hole 111, so that the lint discharging effect is improved.
Referring to fig. 1, in the present embodiment, a through-flow gap G is formed between the pulsator 10 and the tub wall of the washing tub 11, and the through-flow gap G serves as a reverse flow structure, so that during the washing process, the water in the washing tub 11 flows into the space S under the pulsator 10 through the filter cover 20, and finally returns to the washing tub 11 through the through-flow gap G.
In addition, the pulsator 10 also conventionally includes a water-stirring rib formed on an upper surface to push and disturb water flow so that wash water in the washing tub 11 makes a circular motion when the pulsator 10 rotates, and the pulsator 10 also conventionally includes a water-discharging rib formed on a lower surface to cause water flow under the pulsator to be subjected to a centrifugal force to be spread toward edges when the pulsator 10 rotates.
