For those skilled in the art, the specific meanings of the above terms in the present invention can be understood on a case-by-case basis.

Hereinafter, a pulsator washing machine 100 according to an embodiment of the present invention will be specifically described below with reference to the accompanying drawings.

As shown in FIG. 1, a pulsator washing machine 100 according to an embodiment of the present invention includes a body 10, an outer cylinder 20, an inner cylinder 30, and a tub cover 40.

Specifically, in the embodiment of the present invention, the outer cylinder 20 is disposed in the body 10, and the inner cylinder 30 is disposed in the outer cylinder 20. The inner cylinder 30 defines a first chamber 31, and the outer wall surface of the inner cylinder 30 is external. A second chamber 32 is defined between the inner wall faces of the barrel 20. The tub cover 40 is disposed between the inner cylinder 30 and the upper portion of the outer cylinder 20 and extends in the circumferential direction of the outer cylinder 20. In an embodiment of the present invention, the inner wall surface of the tub cover 40 is provided with a plurality of curved water guiding ribs 41 which are arranged along the circumferential direction thereof and are oriented in a uniform direction. Wherein, any two adjacent water guiding ribs 41 define a water flow channel 42 (as shown in FIG. 4), and the water flow channel 42 is electrically connected to the second chamber 32; wherein the water guiding rib is configured to be from The water of the second chamber 32 is introduced into the first chamber 31.

It can be understood that the pulsator washing machine 100 includes an outer cylinder 20 and an inner cylinder 30 disposed in the outer cylinder 20. The pulsator washing machine 100 is further provided with a pulsator 50 disposed at the bottom of the inner cylinder 30 and rotatable so that The water in the inner cylinder 30 generates eddy currents. The bottom of the inner cylinder 30 and the bottom of the outer cylinder 20 are provided with drainage wings 60 which can be rotated to generate centrifugal force and which are driven upward from the water between the inner and outer cylinders 20, and finally introduced into the inner cylinder 30 from the water flow passage 42.

Thus, according to the pulsator washing machine 100 of the embodiment of the present invention, water between the inner cylinder 30 and the outer cylinder 20 can flow into the inner cylinder 30 through the water flow passage 42 formed by the plurality of water guiding ribs 41 during the washing process. Therefore, water can be continuously supplied to the inner cylinder 30 during the washing process, so that the clothes are more loose and less entangled, and the washing effect of the pulsator washing machine 100 is improved.

The shape of the pulsator washing machine 100 according to an embodiment of the present invention may be a shape commonly used by those skilled in the art. Alternatively, as shown in FIG. 3, according to an embodiment of the present invention, the tub cover 40 is formed in a circular shape. That is, the tub cover 40 is formed in a circular ring structure, and the inner wall surface of the tub cover 40 is disposed coaxially with the outer wall surface. Thereby, the length of the water guiding rib 41 extending is long, and the water guiding effect of the water flow passage 42 can be ensured, and the water can be sufficiently introduced into the inner cylinder 30.

Preferably, in accordance with a preferred embodiment of the present invention, the plurality of water guiding ribs 41 are cooperatively formed to extend in a spiral shape in a clockwise or counterclockwise direction. Further, the plurality of water guiding ribs 41 are evenly spaced along the circumferential direction of the tub cover 40.

In other words, each of the water guiding ribs 41 is formed into a circular arc shape having a uniform structure, and the plurality of water guiding ribs 41 are combined to form a direction toward the spiral direction, and each of the water guiding ribs 41 is performed in the same direction clockwise or counterclockwise along the water tank cover 40. Arrange.

In one embodiment of the invention, the water guiding ribs 41 on the tub cover 40 are configured to direct water from the second chamber into the central region of the first chamber.

As shown in Figure 4, in a preferred embodiment of the present invention, the water guiding rib on the tub cover is adapted to introduce water into the first chamber to form a vortex flow in the center of the first chamber (see illustration ). The radius of the vortex flow, viewed from a top view, is approximately 1/3-1/2 of the radius of the lid. In a preferred embodiment of the invention, the radius of the vortex flow, viewed from a top view, is approximately 1/2 of the radius of the lid.

As shown in FIG. 4, in some embodiments of the present invention, the ends of the plurality of water flow passages 42 form a swirl flow in the first chamber 31 centered on the axis of the first chamber 31. Preferably, the radius of the swirl flow is 1/3-1/2 of the radius of the lid 40.

That is, the plurality of water guiding ribs 41 on the tub cover 40 introduce water into the inner cylinder 30, forming a swirling flow in the center of the inner cylinder 30, and the radial dimension of the swirling flow is 1/the radial dimension of the tub 40. 3-1/2. Therefore, the water flow passage 42 formed by the plurality of water guiding ribs 41 can not only introduce the water in the second chamber 32 into the first chamber 31, but also the water discharged from the plurality of water flow passages 42 has less collision and is less likely to splash. The water spray ensures the quality of the washing machine 100.

According to an embodiment of the present invention, the extending direction of each of the water flow passages 42 coincides with the tangential direction of the midpoint of the water guiding rib 41. Thereby, the water flow of the water guiding rib 41 to the outlet is good in continuity, is not easy to splash water, the water flow effect is very smooth, and the water flow rate is large, and the edge area of the entire inner cylinder 30 can be filled to improve the washing effect, and after adding the washing powder, The foam generated in the middle portion of the inner cylinder 30 can be dissipated.

In contrast, when the radial exit angle of the water guiding rib 41 is changed, for example, 5° in the radial direction or 5° in the radial direction, a lot of splashes are generated, and the water flow through the water flow channel 42 is poor. The dissipative effect of the foam is also small, which will reduce the overall quality of the washing machine.

In some embodiments of the present invention, the water guiding ribs 41 are integrally formed on the inner wall surface of the tub cover 40. Thus, the integrally formed tub cover 40 and the water guiding rib 41 not only ensure the overall structural stability and strength of the tub cover 40, but also are convenient to form and reduce the manufacturing cost.

According to the tub cover 40 of the pulsator washing machine of the embodiment of the invention, the tub cover 40 is formed in a ring shape. The inner wall surface of the tub cover 40 is provided with a plurality of curved water guiding ribs 41 which are arranged in the circumferential direction and are oriented in a uniform direction. In a preferred embodiment of the invention, the plurality of water guiding ribs 41 are cooperatively formed to extend in a spiral shape in a clockwise or counterclockwise direction. Preferably, the plurality of water guiding ribs 41 are evenly spaced along the circumferential direction of the tub cover 40.

Thus, when the tub cover 40 is used in the pulsator washing machine 100, the water between the inner cylinder 30 and the outer cylinder 20 can be effectively guided. Into the inner cylinder 30, the washing effect of the pulsator washing machine 100 is improved, the entanglement of the laundry is reduced, and the overall quality of the pulsator washing machine 100 is improved.

Other configurations and operations of the pulsator washing machine 100 in accordance with embodiments of the present invention are known to those of ordinary skill in the art and will not be described in detail herein.
