DETAILED DESCRIPTION

[0024] In order to enable those skilled in the art to better understand the technical solution of the present invention, the technical solution of the present invention is clearly and completely described below in conjunction with the drawings of the present invention. Based on the embodiments in this application, other similar embodiments obtained by ordinary technicians in this field without making creative work should fall within the scope of protection of this application. In addition, the directional words mentioned in the following embodiments, such as "up", "down", "left", "right", etc., are only reference to the directions of the drawings. Therefore, the directional words used are used to illustrate rather than limit the invention.

[0025] The following is combined with Figures 1 to 6 The present invention will be further described.

[0026] The pulsator structure of this embodiment includes: a pulsator frame 35 rotatably disposed within the washing tub 1 of the washing machine to divide the washing tub 1 into an upper chamber 11 and a lower chamber 12; a communication port 36 disposed on the pulsator frame 35 to connect the upper chamber 11 and the lower chamber 12 through the communication port 36; and a pulsator disc 31 disposed within the washing tub 1 and movably connected to the pulsator frame 35. The pulsator disc 31 has a combined state in which it covers the pulsator frame 35 and an open state in which it avoids the communication port 36. With this arrangement, when the bottom of the washing tub 1 of the washing machine needs to be cleaned, the pulsator disc 31 is moved to the open state, allowing the communication port 36 to leak out. The lower chamber 12 can then be cleaned through the communication port 36. This eliminates the need to remove the pulsator disc 31 to complete the cleaning of the lower chamber 12, thereby resolving the inconvenience of cleaning the washing tub of the prior art.

[0027] Specifically, when the washing machine needs to wash clothes, the pulsator disc 31 is moved to the combined state. When the pulsator disc 31 is in the combined state, the pulsator disc 31 rotates together with the pulsator frame 35, thereby washing clothes.

[0028] When the washing machine needs to be cleaned, the impeller 31 is moved to the open state. At this time, the impeller 31 is separated from the impeller frame 35, so that the connecting port 36 leaks out, thereby cleaning the lower cavity 12 through the connecting port 36, achieving the effect of fully cleaning the washing machine.

[0029] See also Figures 2 to 5 In the impeller structure of this embodiment, the impeller structure further includes a connecting component 30, which is connected to both the impeller frame 35 and the impeller disc 31; the impeller frame 35 and the impeller frame 35 are relatively rotatably connected through the connecting component 30.

[0030] In the impeller structure of this embodiment, see Figures 2 to 5 The connecting component 30 includes: a first connecting arm 34, one end of the first connecting arm 34 is connected to the impeller frame 35, and the other end of the first connecting arm 34 has a first connecting portion; a second connecting arm 33, one end of the second connecting arm 33 is connected to the impeller plate 31, and the other end of the second connecting arm 33 has a second connecting portion; the first connecting portion and the second connecting portion are relatively rotatably connected.

[0031] In the impeller structure of this embodiment, see Figure 3The impeller 31 is provided with a receiving groove 311 for accommodating the connecting member 30. When the impeller 31 is in the assembled state, the receiving groove 311 is connected to the upper chamber 11, and the first connecting portion and the second connecting portion are located in the receiving groove 311. This facilitates the concealment of the connecting member 30. In addition, the receiving groove 311 ensures that the operator can operate the first connecting portion and the second connecting portion, thereby moving the connecting member 30 to achieve the effect of moving the impeller 31.

[0032] In the impeller structure of this embodiment, see Figure 2 、 Figure 3 and Figure 6 The pulsator structure further includes a pulsator cover 32, which is detachably mounted on the receiving groove 311 to close or avoid the connecting component 30. In this way, when the washing machine does not need to be cleaned, the pulsator cover 32 is covered to ensure that the pulsator structure can perform the washing operation normally.

[0033] See attached Figure 3 and Figure 6 In the impeller structure of this embodiment, a first snap 321 and a second snap 322 are provided on the impeller cover 32. The first snap 321 and the second snap 322 are arranged at intervals, and the two side walls of the accommodating groove 311 are respectively provided with snap slots 312 that cooperate with the first snap 321 and the second snap 322.

[0034] With the above arrangement, the impeller cover 32 can be installed and removed by squeezing the first clip 321 and the second clip 322, which is easy to operate.

[0035] In the impeller structure of this embodiment, the connecting component 30 is rotatably connected to the impeller frame 35 relative to each other; and / or, the connecting component 30 is rotatably connected to the impeller plate 31 relative to each other.

[0036] In the impeller structure of this embodiment, see Figure 5 The impeller frame 35 includes: a connecting frame 351, which is a ring structure, and the impeller plate 31 is relatively movably connected to the connecting frame 351; a rotating component 352, which is located in the connecting frame 351; and a supporting component 353, wherein one end of the supporting component 353 is connected to the rotating component 352, and the other end of the supporting component 353 is connected to the connecting frame 351.

[0037] In some embodiments, the connecting component 30 is disposed above the supporting component 353 , which is beneficial for limiting the position of the connecting component 30 and also beneficial for sealing the connecting component 30 .

[0038] In the impeller structure of this embodiment, there are multiple supporting components 353 , and the multiple supporting components 353 are arranged around the rotating component 352 , and the communication port 36 is arranged between two adjacent supporting components 353 .

[0039] The washing machine of this embodiment includes a impeller structure 3, which is the above-mentioned impeller structure. The washing machine includes: a washing shaft 5, which is arranged on the body 2 of the washing machine, and the washing shaft 5 passes through the base 4 of the washing tub 1 of the washing machine. The washing shaft 5 is connected to the impeller frame 35 of the impeller structure 3.

[0040] The steps for installing the pulsator structure of the washing machine of this embodiment are as follows:

[0041] In this embodiment, the impeller frame 35 of the middle impeller structure 3 is connected to the washing shaft 5 by a spline connection, and the washing tub 1, body 2, base 4, washing shaft 5 and clutch motor assembly are installed in the same manner as a conventional washing machine.

[0042] The first connecting arm 34 is connected to the impeller frame 35 in a rotatable manner; one end of the second connecting arm 33 is rotatably connected to the first connecting arm 34, and the other end is rotatably connected to the impeller disc 31; the impeller cover 32 is assembled with the impeller disc 31 by means of a snap or other limiting means.

[0043] After the impeller cover 32 is assembled, the snap features (first snap 321 and second snap 322) on the impeller cover 32 cooperate with the snap slot 312 on the side wall of the accommodating groove 311 to cover the connecting component 30 from the appearance. At the same time, the connecting component 30 can be limited to prevent it from rotating.

[0044] The working principle of the pulsator structure of the washing machine of this embodiment is as follows:

[0045] First, separate the impeller cover 32 from the impeller disc 31. Because it is a snap fit limiter, the impeller cover 32 is easy to take out. You can take out the impeller cover 32 by squeezing or prying the snap cantilever. Then, pull up the second connecting arm 33 and the first connecting arm 34. Driven by the second connecting arm 33, the impeller disc 31 is also pulled up. This process is as follows: Figure 4 Then, the impeller 31 is turned over at a certain angle with the connection between the first connecting arm 34 and the impeller frame 35 as the axis. The turning angle is suitable for cleaning the bottom of the inner cylinder. Figure 6 .

[0046] After the impeller disc 31 is flipped over, the impeller frame 35 is exposed. Most of the structure of the impeller frame 35 is hollowed out and no longer blocks the bottom of the inner drum. We can clean the bottom of the inner drum or the base of the inner drum to remove the dirt hidden at the bottom and keep the washing machine clean and hygienic. After cleaning, the impeller disc 31, the second connecting arm 33 and the first connecting arm 34 are reset, and finally the impeller cover 32 is installed. After assembly, the connecting component 30 can be obscured from the outside and the connecting component 30 can be limited to prevent it from rotating.

[0047] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0048] The pulsator structure of the present invention includes a pulsator frame 35 rotatably disposed within a washing tub 1 of a washing machine to divide the washing tub 1 into an upper chamber 11 and a lower chamber 12; a communication port 36 disposed on the pulsator frame 35 to connect the upper chamber 11 and the lower chamber 12 through the communication port 36; and a pulsator disc 31 disposed within the washing tub 1 and movably connected to the pulsator frame 35. The pulsator disc 31 has a combined state in which it covers the pulsator frame 35 and an open state in which it avoids the communication port 36. With this arrangement, when the bottom of the washing tub 1 of the washing machine needs to be cleaned, the pulsator disc 31 is moved to the open state, allowing the communication port 36 to leak out. The lower chamber 12 can then be cleaned through the communication port 36. This eliminates the need to remove the pulsator disc 31 to complete the cleaning of the lower chamber 12, thereby resolving the inconvenience of cleaning the washing tub of a washing machine in the prior art.
