Problems solved by technology

During the flipping process, the clothes (especially clothes with slender structures, such as trouser legs, sleeves, etc.) will be entangled with each other. After dehydration, the clothes will be more entangled and difficult to separate, causing troubles to users
[0003] A washing machine pulsator with a patent number of ZL201120489211.8 and a washing machine pulsator with a patent number of ZL201210046667.6 both disclose a structure with protruding blades on the pulsator base, but the pulsator base has a protruding The shape of the blade and the setting of the concave-convex position on it are of great significance to achieve low winding. The design of the raised blade in the above two patents has a certain effect of reducing winding, but the setting of the impeller structure is relatively simple. In order to better achieve low-entanglement laundry, further improvements to the pulsator are required

Embodiment 1

[0027] Such as figure 1 As shown, a low-wound pulsator includes a wheel seat, a central protrusion 1 arranged on the wheel seat, and a rib 2 connected to the central protrusion 1 and evenly distributed on the wheel seat around the circumference of the wheel seat. The ribs include a convex edge located in the middle and a curved surface on both sides of the convex rib connecting the top of the convex rib and the upper surface of the wheel seat. The arc surfaces on both sides are symmetrically distributed. The bottom of the curved surface is large and gradually converges and shrinks upward. The convex rib is located on the periphery of the wheel seat. The ends of the ridges gradually expand from the middle to the two sides, and the number of ribs is 3-6. In this embodiment, the number is 4.

[0028] Such as figure 1 As shown, when viewed from a direction parallel to the central axis of the wheel base, the bottom of the arc on both sides of the ribs changes from the periphery of the ...

Embodiment 2

[0042] A low-wrapping washing machine is equipped with the pulsator mentioned in the first embodiment. When washing, as the pulsator 7 rotates, the laundry is in the inner tub 8 of the washing machine, from the periphery of the pulsator to the center of the center of the pulsator. Move up and climb up along the central bulge, then move to the inner barrel 8, move down the inner barrel to the bottom of the inner barrel, and then climb upward from the periphery of the pulsator toward the center of the pulsator, repeat the above actions. Since the wheel seat of the pulsator is provided with a central protrusion and a rib, and the position of the rib near the center protrusion is low, and the position far away from the center protrusion is high, forming an arc-shaped curve with high outer and inner low, and the convex ribs The positions of the highest point and the lowest point of the position where the ribs are close to the central bulge are optimally defined, so the low entangleme...

Embodiment 3

[0045] The low-wrap washing method described in this embodiment adopts the washing machine described in the second embodiment. When the pulsator of the washing machine rotates, the single rotation time of the pulsator is 0.6-1 second. In this embodiment, the single rotation The rotation time is 0.8 seconds.

[0046] The stop time between two rotations is less than 0.6 seconds. Taking into account the different transmission modes of washing machines, washing machines based on direct drive mode should minimize the stopping time as much as possible; for washing machines that use BLDC MOTOR and drive mode by deceleration device, 0.3 seconds is preferred; belt drive mode is preferably 0.4 seconds . In this embodiment, a washing machine using a BLDC MOTOR driven by a decelerating device is selected for washing, and the stopping time between two rotations is 0.3 seconds.

[0047] The present invention is a low-entanglement washing method, which further optimizes and limits the pulsating...

Abstract

The invention provides a low-tangling impeller comprising an impeller base, a center projection on the impeller base and protruding ribs arranged on the impeller base uniformly and connected to the center projection. Each protruding rib comprises a protruding ridge in the middle and arc-shaped surfaces arranged at the two sides of the protruding ridge to connect the top of the protruding ridge and the upper surface of the impeller base, wherein the arc-shaped surfaces have large bottoms and narrow and shrink gradually upward. The intersecting lines between the arc-shaped surfaces on the two sides of the protruding ridges and the upper surface of the impeller base are curved lines and the curved lines include a plurality of continuous arc lines including inward-concave arc lines, outward-protruding arc lines and inward-concave arc lines arranged from the center of the impeller base to the periphery of the impeller base successively. The end, on the periphery of the impeller base, of each protruding ridge extends gradually from the middle portion to the two sides. The invention also provides a low-tangling washing machine comprising the impeller and a low-tangling washing method. The washing machine is characterized in that the time for a single rotation of the impeller is 0.6-1s and the stop time between two rotations is less than 0.6s. During washing, the protruding ribs with higher outer parts and lower inner parts and the center projection of the impeller can prevent clothes from tangling. Clothes tangling can be further prevented by controlling the rotation and stop time of the impeller.

Description

Technical field [0001] The invention relates to a pulsator, a washing machine and a method, in particular to a low-winding pulsator, a washing machine and a low-winding washing method, belonging to the field of washing machines. Background technique [0002] The pulsator washing machine adopts the scroll type for washing. During the washing process, the clothes will be constantly turned over. During the turning process, clothing (especially clothing with a slender structure, such as trouser legs, sleeves, etc.) will be entangled with each other. After dehydration, the clothing will be entangled severely and it is difficult to separate, causing trouble to users. . [0003] A washing machine pulsator with patent number ZL201120489211.8 and a washing machine pulsator with patent number ZL201210046667.6, although both disclose a structure with raised blades on the pulsator base, but the pulsator base is convex The shape of the blade and the setting of its concave and convex positions...
