The outer drum is fixedly arranged in the box body, the inner drum is rotatably arranged in the outer drum, and the pulsator is rotatably arranged at the bottom of the outer drum. When the pulsator washing machine performs washing and rinsing operations, the pulsator drives the washing water and the clothes in the outer drum to rotate, so as to achieve the purpose of cleaning the clothes. When the pulsator washing machine performs spinning operation, the inner drum drives the clothes in it to rotate at high speed, so that the water on the clothes is separated from the clothes under the action of centrifugal force. During the use of the pulsator washing machine, the following problems often exist: firstly, when there are too many foams in the washing process, it is not easy to efficiently and quickly defoam; secondly, the existing spraying device cannot provide comprehensive and strong water flow, and cannot achieve better spraying effect; thirdly, the existing spraying structure is complex, inconvenient to make, high in cost and time-consuming and laborious to install.

[0003] In order to solve the above problems, the existing pulsator washing machine usually sets a spraying device on the outer drum cover. For example, the patent document with the announcement number CN204282066U discloses a pulsator washing machine, and a plurality of nozzles are arranged on the outer drum cover of the pulsator washing machine. When the pulsator washing machine works, a circulating water pump can pump the washing water in the outer drum to the plurality of nozzles, so that the plurality of nozzles spray the washing water onto the clothes in the inner drum.

[0059] The present invention will be further described in detail below with reference to the embodiments.

[0060] Example 1

[0061] like Figures 1-14 As shown, where Figure 1 This is a schematic diagram of the position of the spray device 3 in a pulsator washing machine. The spray device 3 includes a rotating spray component 31 that can rotate freely around a central rotation axis. The rotating spray component 31 has a spray chamber 34 inside, and the peripheral side wall of the rotating spray component 31 is provided with a drive spray nozzle 32 that is connected to the spray chamber 34 and is used to drive the rotating spray component 31 to rotate.

[0062] The spray water in the spray chamber 34 is sprayed outward by the drive spray nozzle 32 along the direction of the center line of the drive spray nozzle 32. The center line of the drive spray nozzle 32 does not pass through the central rotation axis, so as to drive the rotating spray component 31 to rotate around the central rotation axis. It should be understood that the drive spray nozzle 32 at this time not only provides driving force, but also sprays the clothes in the washing machine.

[0063] like Figures 2-6 As shown, it should be understood that the rotating spray component 31 in this embodiment has a housing with a spray cavity 34 inside. The housing includes an upper cover 311 and a lower cover 312. The upper cover 311 and the lower cover 312 are fitted together to form the rotating spray component 31, and the spray cavity 34 is formed inside.

[0064] Preferably, the upper cover 311 and the lower cover 312 are connected and fixed by hot plate cladding, ultrasonic welding or bonding. Of course, any other connection and fixing method with the same or better effect can be used, which is not limited here.

[0065] The rotating spray member 31 comprises a spray body in the shape of a long strip, and the driving water outlet 32 is arranged at a position close to the left and right two side ends of the spray body.

[0066] Preferably, along the length direction of the spray body, the spray body comprises oppositely arranged first and second side walls, and the driving water outlet 32 is arranged at a position close to the two side ends on the first or second side wall. It should be understood that the specific shape of the spray body or the rotating spray member 31 can be selected according to actual conditions, and there is no strict limitation, but it can be understood that the specific shape is generally designed or considered from the angles of the internal structure of the washing machine, saving kinetic energy, etc.

[0067] As shown in FIGS. Figure 7 , 10 and 11, the driving water outlet 32 is a first cylindrical hole with a constant inner diameter; or the driving water outlet 32 is a first tapered hole with a gradually decreasing inner diameter along the water flow injection direction; or the driving water outlet 32 is a first stepped hole with a gradually decreasing inner diameter along the water flow injection direction. The latter two designs of the driving water outlet 32 can increase the water pressure to a certain extent, and can improve the driving force to a certain extent.

[0068] As shown in FIGS. Figures 8-11 , the bottom wall of the rotating spray member 31 is further provided with a spray water outlet 33 connected with the spray cavity 34 for spraying and washing clothes. The rotating spray member 31 can not only be provided with the driving water outlet 32, but also can be provided with the spray water outlet 33, and the driving and spraying are divided into two operations, and the spraying and driving effects are better.

[0069] Preferably, along the length direction of the spray body, the rotating spray member 31 has oppositely arranged first and second ends, the driving water outlet 32 is arranged at a position close to the first end on the side wall of the rotating spray member 31, and the spray water outlet 33 is arranged at a position close to the second end on the bottom wall of the rotating spray member 31.

[0070] Alternatively, the driving water outlet 32 is arranged at a position close to the first end on the side wall of the rotating spray member 31, and the spray water outlet 33 is arranged at a position close to the first end on the bottom wall of the rotating spray member 31.

[0071] Alternatively, the driving water outlet 32 is arranged at a position close to the second end on the side wall of the rotating spray member 31, and the spray water outlet 33 is arranged at a position close to the second end on the bottom wall of the rotating spray member 31. It should be understood that the above statements are only possible choices of the position arrangement, and the driving water outlet 32 and the spray water outlet 33 are not limited to the above position limitation.

[0072] It should be understood that the spray outlet 33 and the driving water outlet 32 are arranged on the lower cover body 312, and of course the driving water outlet 32 can also be arranged on the upper cover body 311.

[0073] The spray outlet 33 is a second cylindrical hole with a constant inner diameter, or the spray outlet 33 is a second conical hole with a gradually decreasing inner diameter along the water flow spraying direction, or the spray outlet 33 is a second stepped hole with a gradually decreasing inner diameter along the water flow spraying direction. The last two design ideas of the spray outlet 33 can effectively improve the water pressure intensity of the sprayed water flow, and can better wash the clothes and the like.

[0074] As shown in Figure 12 and 13 The spray outlet 33 is provided with a pressure increasing and direction changing structure for increasing water pressure and / or changing water spraying direction; the pressure increasing and direction changing structure has a plurality of water flow channels or water spraying holes 361 extending in different directions, and the water in the spray cavity 34 is dispersed and sprayed in all directions through the water flow channels or water spraying holes 361.

[0075] The rotating spray part 31 further comprises a second mounting sleeve 35 fixedly connected at one end to the outer periphery of the spray outlet 33, and the pressure increasing and direction changing structure is rotatably limited on the end of the second mounting sleeve 35 close to the spray outlet 33.

[0076] Preferably, the sleeve wall of the second mounting sleeve 35 is provided with a plurality of water permeable holes 351 communicating with the spray cavity 34, and the water in the spray cavity 34 enters the second mounting sleeve 35 through the water permeable holes 351 and is dispersed and sprayed in all directions through the water flow channels or water spraying holes 361.

[0077] It should be understood that since the rotating spray part 31 in the embodiment is formed by the upper cover body 311 and the lower cover body 312, the second mounting sleeve 35 also has two parts, including an upper mounting sleeve 352 and a lower mounting sleeve 353, the upper mounting sleeve 352 is arranged in the upper cover body 311, the lower mounting sleeve 353 is arranged in the lower cover body 312, and the pressure increasing and direction changing structure is rotatably limited on the end of the lower mounting sleeve 353 close to the spray outlet 33.

[0078] Preferably, the sleeve wall of the upper mounting sleeve 352 and the lower mounting sleeve 353 is provided with a plurality of water permeable holes 351 communicating with the spray cavity 34, and the water in the spray cavity 34 enters the second mounting sleeve 35 through the water permeable holes 351 and is dispersed and sprayed in all directions through the water flow channels or water spraying holes 361, and is sprayed on the clothes.

[0079] More preferably, the pressure boosting reversing structure is a universal bead 36. It should be understood that the pressure boosting reversing structure can be irregular in shape, and can also have elastic properties, etc., which are not limited here.

[0080] It should be understood that the second mounting sleeve 35 is provided to better position or locate the pressure boosting reversing structure at the spray water outlet 33. Since the pressure boosting reversing structure has a plurality of water flow passages or water spray holes 361 extending in different directions on the top, the water in the spray cavity 34 is dispersed and sprayed in all directions through the water flow passages or water spray holes 361, which not only enhances the water pressure and improves the cleaning degree of the spray, but also enables the rotation of the rotating spray member 31 to obtain omnidirectional spraying in the washing machine and improve the spraying efficiency.

[0081] As shown in Figure 14 The spray device 3 also includes a transition structure, i.e., a rotating connecting member 7, which is rotatably and sealingly connected to the rotating spray member 31.

[0082] Preferably, the rotating spray member 31 is provided with a water inlet 41 on the top wall, and a connecting sleeve 72 is fixedly arranged on the water inlet 41. The rotating connecting member 7 includes a connecting pipe 71 rotatably connected to the connecting sleeve 72 through a bearing structure 73. One end of the connecting pipe 71 is in communication with the spray cavity 34, and the other end is in communication with an external water inlet pipe 4.

[0083] More preferably, a sealing ring is arranged around the connecting pipe 71 in the connecting sleeve, and the sealing ring is sealingly connected between the connecting pipe 71 and the connecting sleeve 72.

[0084] The connecting sleeve 72 is arranged on the top wall of the rotating spray member 31, and the connecting sleeve 72 is in a hollow cylindrical shape. An annular stepped clamping step is arranged on the upper end of the connecting sleeve 72 for placing the bearing structure 73.

[0085] It should be understood that the rotating connecting member 7 is only one embodiment for realizing the rotatable sealing function, and any other existing or designed components using bearing principles can be applied to the present embodiment, which is not limited further.

[0086] This embodiment presents a spray device 3 that can uniformly spray a strong water flow onto the clothes in the inner tub, improving the cleanliness of the clothes and enhancing the rinsing performance of the washing machine. This device only requires water flow to provide rotational power, eliminating the need for an additional motor, thus saving energy. The rotating connector 7 is directly connected to the water inlet 41 of an external water source. Based on the unique structure of the spray device 3, the water injected into the rotating connector 7 not only provides the power for the rotation of the spray device 3 but also sprays a strong, omnidirectional water flow from the spray outlet 33 to wash the clothes, achieving a better spraying effect. Furthermore, the spray device 3 has a simple and reliable structure, facilitating installation and maintenance.
