DETAILED DESCRIPTION

[0050] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0051] In the description of the present invention, it should be noted that the directions or positional relationships indicated by terms such as “upper”, “lower”, “front”, “back”, “left”, “right”, “vertical”, “inside” and “outside” are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0052] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0053] like Figures 1 to 10 As shown, the present invention provides a washing machine outer drum cover structure, which can close the drum mouth of the outer drum 4 to prevent water in the outer drum 4 from splashing to the outside during the operation of the washing machine.

[0054] The outer barrel cover structure comprises an outer barrel cover 1 , an inner cover 2 and a rotary spraying device 3 .

[0055] The outer barrel cover 1 is provided with an opening 11, and the inner cover 2 is rotatably arranged on the outer barrel cover 1 for closing or opening the opening 11. The inner cover 2 can be rotated toward the outside of the outer barrel cover 1 to open the opening 11. The rotary spraying device 3 is arranged on the inner cover 2. The rotary spraying device 3 includes a spray head 31, and the spray head 31 is rotatably arranged on the inner side wall of the inner cover 2.

[0056] The present invention provides a rotatable inner cover 2 on the outer barrel cover 1, and a rotary spray device 3 is provided on the inner side of the inner cover 2. By rotating the spray water inlet, the clothes in the outer barrel 4 can be sprayed for washing or rinsing, thereby increasing the spray range of the clothes, thereby improving the spray rinsing efficiency of the clothes, washing the clothes in all directions, improving the washing effect of the clothes, saving water and energy, and having a simple structure and occupying a small space.

[0057] In the above structure, if the outer drum cover structure is installed on the outer drum 4 of the washing machine, the nozzle 31 on the inner wall of the inner cover 2 extends downward too low, which is easy to scratch or entangle with the clothes in the outer drum 4 when the clothes are spun or washed, affecting the normal operation of the washing machine.

[0058] In view of this, the present invention provides a concave cavity 221 on the inner side of the inner cover 2 , and the nozzle 31 is disposed in the concave cavity 221 .

[0059] By setting the nozzle 31 inside the concave cavity 221 of the inner cover 2, it can avoid being entangled with clothes when the washing machine is running after being installed on the outer barrel 4 of the washing machine. The nozzle 31 can be rotatably set inside the concave cavity 221, and the structure volume is small, and does not occupy the space under the outer barrel cover structure.

[0060] Preferably, the opening 11 is disposed in the middle of the outer barrel cover 1, and the concave cavity 221 is disposed in the middle of the inner cover 2. The transverse cross-section of the concave cavity 221 is circular.

[0061] In the above structure, a water inlet pipeline needs to be set up to supply water to the rotary spray device 3. If the water inlet pipeline is directly set on the inner wall or outer wall of the outer barrel cover structure, the water inlet pipeline will easily rub against other objects and the appearance will be unsightly, affecting the user experience.

[0062] like Figures 2 to 8 As shown, the rotary spraying device 3 further includes a connecting pipe 33 and a fixing seat 32 .

[0063] The liquid inlet end of the connecting tube 33 is arranged outside the inner cover 2 , and the liquid outlet end of the connecting tube 33 extends to the inside of the inner cover 2 , so as to allow liquid to flow from the outside to the inside of the inner cover 2 .

[0064] The fixing seat 32 has a water inlet channel inside. One end of the fixing seat 32 is arranged inside the inner cover 2, and is connected to the liquid outlet end of the connecting pipe 33, so that the incoming liquid is introduced into the water inlet channel of the fixing seat 32. The other end of the fixing seat 32 is passed through the concave cavity 221 outside the inner cover 2, and is connected to the spray head 31, so that the incoming liquid is guided to the spray head 31 to spray the clothes in the outer barrel 4.

[0065] The present invention sets a fixing seat 32 penetrating the interior of the inner cover 2, and a connecting pipe 33 is set from the outside to the interior of the inner cover 2, so as to guide the incoming liquid to one end of the fixing seat 32 in the inner cover 2, and supply liquid to the nozzle 31 through the other end of the fixing seat 32 set in the concave cavity 221, so as to realize liquid inlet to the nozzle 31. The present invention extends the connecting pipe 33 in the inner cover 2, and the fixing seat 32 does not protrude outward from the concave cavity 221. The liquid inlet pipeline is cleverly designed to make full use of the space inside the inner cover 2 and the concave cavity 221. There is no need to set the liquid inlet pipeline on the side wall or outside the side wall of the inner cover 2. The connection structure is simple, does not occupy additional external space, has a small size, and has a beautiful appearance.

[0066] Preferably, the fixing seat 32 is extended along the axial direction of the inner cover 2 , and the water inlet channel is extended inside the fixing seat 32 along the extension direction of the fixing seat 32 .

[0067] The spray head 31 is rotatably mounted on the peripheral wall of the other end of the fixed seat 32, and is connected to the peripheral wall of the fixed seat 32, so as to guide the liquid from the fixed seat 32 into the spray head 31. The bottom wall of the spray head 31 is provided with an inclined liquid outlet hole for spraying water to drive the spray head 31 to rotate.

[0068] When the spray head 31 is filled with liquid, the liquid inlet hole sprays the liquid downward at an angle, and under the action of the circumferential reaction force, the spray head 31 is driven to rotate, so that the spraying range is wider, and there is no need to set a drive rotation.

[0069] The inner diameter of the liquid inlet hole gradually decreases as it extends from the inside of the nozzle 31 to the outside.

[0070] like Figures 4 to 8 As shown, a protruding annular mounting portion 321 is provided on the peripheral wall of the fixing seat 32 , which is located in the concave cavity 221 and connected to the outer periphery of the connecting hole 222 on the cavity bottom of the concave cavity 221 .

[0071] The rotary spraying device 3 further includes a limit plate 35 and a connecting member 36. The limit plate 35 is connected to the other end of the fixing seat 32 via the connecting member 36, and the spray head 31 is limited between the limit plate 35 and the annular mounting portion 321.

[0072] Preferably, the limiting plate 35 is circular. The fixing seat 32 is cylindrical with an annular mounting portion 321 on the outer peripheral wall. The other end of the fixing seat 32 has a screw hole, and the connecting member 36 is a screw that passes through the limiting plate 35 and is connected to the screw hole.

[0073] The annular mounting portion 321 is provided with an assembly hole, which is connected to the upper inner cover 21 at the outer periphery of the connection hole 222 by screws. The outer diameter of the limiting plate 35 is greater than the outer diameter of one end of the fixing seat 32.

[0074] A communication hole 322 is formed on the outer peripheral wall of the other end of the fixing seat 32 and is communicated with the nozzle 31 .

[0075] Furthermore, the spray head 31 includes a connected annular seat 311 and a plurality of spray arms 312. The annular seat 311 is sleeved on the outer periphery of the other end of the fixed seat 32 and is connected to the connecting hole 322 of the fixed seat 32. The spray arms 312 are arranged at intervals on the outer peripheral wall of the annular seat 311 and extend from the peripheral wall of the annular seat 311 to the outer periphery.

[0076] The liquid outlet is arranged obliquely downward toward the center direction of the outer barrel cover 1 , and the liquid outlet direction deviates from the radial line of the outer barrel cover 1 in the circumferential direction.

[0077] The annular seat 311 is sealed and installed with the outer peripheral walls of the upper and lower sides of the connecting hole 322 of the fixed seat 32 through the sealing ring 37 to prevent water leakage at the connection between the fixed seat 32 and the spray head 31 during the operation of the rotary spray device 3.

[0078] In the present invention, the liquid outlet is inclined toward the center direction of the outer barrel cover 1, and multiple spray arms 312 spray inward, gradually tilting to spray to the inner edge of the outer barrel 4, which can increase the spray range. Secondly, the liquid outlet direction of the spray head 31 deviates from the radial line of the outer barrel cover 1 in the circumferential direction, and a reaction force can be formed in the circumferential direction during spraying to push the spray head 31 to rotate.

[0079] The liquid outlet hole on each spray arm 312 can be a spray hole 313, which is inclined downward toward the middle of the inner cover 2 and circumferentially deviated from the radial arrangement of the spray head 31, thereby driving the spray head 31 to rotate.

[0080] Alternatively, the liquid outlet on each spray arm 312 includes a plurality of spray holes 313 , which are arranged at intervals along the length extension direction of the spray arm 312 at the bottom of the spray arm 312 and inclined downward toward the inner circumference, and the arrangement extension direction of the plurality of spray holes 313 deviates from the radial direction of the nozzle 31 .

[0081] Each spray arm 312 has a chamber, which is respectively communicated with the annular seat 311. The multiple spray holes 313 on each spray arm 312 are arranged and extend in the same direction.

[0082] The spray arms 312 are rotating blades, and the number of the rotating blades is 2 to 5, preferably 3, and they are evenly spaced along the circumference of the annular seat 311 .

[0083] like Figures 3 to 5 As shown, the inner cover 2 comprises an upper inner cover 21 and a lower inner cover 22 which are buckled together to form a receiving space. An extending guide groove 211 is provided on the inner side wall of the upper inner cover 21, and the connecting pipe 33 is extended and arranged in the guide groove 211.

[0084] The liquid inlet end of the connecting pipe 33 extends through the outer periphery of the inner cover 2 , and one end of the fixing seat 32 extends into the guiding groove 211 and communicates with the liquid outlet end of the connecting pipe 33 .

[0085] The outer side (or upper side wall) of the upper inner cover 21 is partially protruded outward to form a protruding portion 212 , and the guide groove 211 is provided in a receiving cavity formed by the protruding portion 212 on the inner side of the upper inner cover 21 .

The first protrusion 2121 is disposed in the middle of the upper inner cover 21 , and the second protrusion 2122 extends from the first protrusion 2121 to the outer peripheral edge of the upper inner cover 21 .

[0087] The first protrusion 2121 is provided with an annular rib on the inner side, and the inner circumference of the annular rib forms a first accommodation cavity. The second accommodation cavity formed by the second protrusion 2122 on the inner side of the upper inner cover 21 forms a part of the guide groove 211 for installing the connecting pipe 33. The second accommodation cavity is connected with the first accommodation cavity to form the guide groove 211.

[0088] The protruding height of the first protruding portion 2121 is greater than that of the second protruding portion 2122, so that the first accommodation cavity formed by the annular convex rib inside the first protruding portion 2121 has a deeper depth. The liquid outlet end of the connecting pipe 33 has a conversion joint 331, which is installed in the first accommodation cavity formed in the annular convex rib. One end of the fixing seat 32 extends into the first accommodation cavity and is sealed and connected to the conversion joint 331.

[0089] The first protrusion 2121 is a circular boss, and the second protrusion 2122 is a strip-shaped protrusion.

[0090] The concave cavity 221 is formed by the upward protrusion of part of the side wall of the lower inner cover 22, and the protruding part abuts against the annular convex rib. The annular convex rib and the lower inner cover 22 are respectively provided with mounting holes, which match the assembly holes of the annular mounting portion 321, and the three are connected together by screws.

[0091] Furthermore, the outer barrel cover structure also includes a water inlet pipe 12 .

[0092] The water inlet pipe 12 is fixed on the outer barrel cover 1, and a rotatable reversing joint 34 is provided at the liquid inlet end of the connecting pipe 33, which rotates with the inner cover 2 so that the rotating inner cover 2 can be connected to the fixed water inlet pipe 12. The reversing joint 34 is detachably connected to the water inlet pipe 12.

[0093] The water inlet pipe 12 is fixed on the outer barrel cover 1 through the water inlet pipe assembly seat 15 and cannot rotate.
