Description

Technical Field

[0001] The utility model relates to the technical field of washing machines, in particular to a large washing machine inner drum with a sound insulation function. Background Art

[0002] A pulsator washing machine is a common type of washing machine. Its inner drum is mostly called a washing tub, and the outer drum is mostly called a water tub. There is a pulsator at the bottom of the inner drum of the washing machine. The rotation of the inner drum can stir the water flow, so that the clothes are driven by the water flow to tumble, and the clothes are washed one by one. However, the inner drum of a general pulsator washing machine is mostly only connected to the outer drum at the bottom and top, and there is little supporting structure between the outer wall of the inner drum and the inner wall of the outer drum. The shock absorption system of the pulsator washing machine is mostly installed on the outer drum of the washing machine, resulting in the vibration of the inner drum due to the disturbance of the internal water flow when the pulsator washing machine is working, especially during the dehydration process. The vibration of the inner drum is indeed easy to cause vibration of the inner drum due to the small number of connections with the outer drum, and the vibration transmission effect is poor, which is easy to cause noise and is more inconvenient. In addition, the disturbance of the water flow can easily impact the inner drum wall, causing the top or bottom connection between the inner drum and the outer drum to be subjected to greater pressure, which can easily cause the connection to loosen and increase wear problems, which is more inconvenient.

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] See also Figures 1-6 In an embodiment of the present invention, a large washing machine inner drum with a sound insulation function is provided, comprising:

[0025] The water tub 100, the washing tub 200, the moving mechanism 300 and the supporting mechanism 400 capable of supporting the washing tub 200, the inner wall of the water tub 100 is provided with a plurality of slide grooves 101, the top of the water tub 100 is detachably connected to a water isolation ring 110, the washing tub 200 is located inside the water tub 100, the top of the washing tub 200 includes a balance ring, and the top of the balance ring is fixedly connected to an annular guide rail 210, the bottom surface of the water isolation ring 110 is fixedly connected to a convex ring 111, and the bottom surface of the convex ring 111 is fixedly connected to a plurality of protrusions 112, and the plurality of protrusions 11 2 are slidably engaged in the annular guide rail 210, the moving mechanism 300 is located on the top surface of the water isolation ring 110, the supporting mechanism 400 is located between the water tub 100 and the washing tub 200, the supporting mechanism 400 includes a main ring 410, and a secondary ring 420 is provided inside the main ring 410, and a plurality of rollers 430 are provided between the main ring 410 and the secondary ring 420, and both ends of any roller 430 are rotatably connected to a support arm, and one end of any support arm is fixedly connected to the inner wall of the main ring 410, and the outer wall of the secondary ring 420 is in contact with the outer walls of the plurality of rollers 430.

[0026] Specifically, during installation, after placing the washing tub 200 into the water tub 100, the main ring 410 and the secondary ring 420 are placed between the washing tub 200 and the water tub 100, and then the water isolation ring 110 is fixed to the top of the water tub 100 through the connecting piece, so that the multiple protrusions 112 on the convex ring 111 are located inside the annular guide rail 210, thereby positioning the washing tub 200. When the washing tub 200 is dehydrated or rotated at high speed, the washing tub 200 can drive the secondary ring 420 to rotate, so that the secondary ring 420 rotates on multiple rollers 430, so that the outer wall of the washing tub 200 is supported by the main ring 410, the secondary ring 420 and the rollers 430, thereby increasing the support surface of the inner drum of the washing machine, sharing the pressure at the connection between the inner drum and the outer drum of the washing machine, and making the vibration of the inner drum of the washing machine more easily transmitted to the outer drum, and then the vibration is reduced by the shock-absorbing device on the outer drum, thereby reducing noise and achieving a sound insulation effect. Example 1

[0027] like Figure 5 As shown, in this embodiment, multiple protrusions 112 are all hemispherical structures, multiple annular grooves are opened on the outer walls of multiple rollers 430, and multiple guide rings 421 are fixedly sleeved on the outer wall of the secondary ring 420, and multiple guide rings 421 correspond one-to-one to the multiple annular grooves on any roller 430, and any guide ring 421 is located inside the corresponding annular groove, multiple clamping blocks are fixedly connected to the outer wall of the main ring 410, and multiple clamping blocks correspond one-to-one to multiple slide grooves 101, and multiple clamping blocks are slidably clamped inside the corresponding slide grooves 101, rubber rings 440 are fixedly sleeved on both ends of the top and bottom of the inner wall of the main ring 410, and snap rings 422 are fixedly connected on both sides of the top and bottom of the secondary ring 420, and the two rubber rings 440 are each provided with a clamping groove on one adjacent side, and the two clamping rings 422 are rotatably sleeved inside the two clamping grooves respectively.

[0028] In this embodiment, the plurality of protrusions 112 are hemispherical in shape, which reduces the contact surface between the protrusions 112 and the annular guide rail 210, thereby facilitating the rotation of the protrusions 112 within the annular guide rail 210. The plurality of guide rings 421 engage the annular grooves on the roller 430, thereby ensuring that the secondary ring 420 is always located within the primary ring 410, preventing the secondary ring 420 from separating from the primary ring 410. Furthermore, the retaining ring 422 engages the retaining grooves on the rubber ring 440, preventing water from flowing into the tub 100 from flowing between the primary and secondary rings 410. When installing the primary ring 410, the retaining blocks on the primary ring 410 can be inserted into the chute 101 on the tub 100 to prevent the primary ring 410 from rotating.

[0029] like Figure 6 As shown, in this embodiment, the outer wall of the main ring 410 and the inner wall of the secondary ring 420 are fixedly connected with Velcro hook surfaces, and the main ring 410 and the secondary ring 420 are both equipped with cleaning cloths 401, and one side of either cleaning cloth 401 is provided with Velcro fur surfaces.

[0030] In specific implementation, when in use, the cleaning cloth 401 can be attached to the outer wall of the main ring 410 and the inner wall of the secondary ring 420 using Velcro, so that one side of the cleaning cloth 401 is a Velcro surface and the other side has multiple densely arranged plastic protrusion structures. The main ring 410 and the secondary ring 420 can be moved to make the plastic protrusion structure on the cleaning cloth 401 scrape the inner wall of the water tub 100 and the outer wall of the washing tub 200, thereby scratching the inner wall of the water tub 100 and the outer wall of the washing tub 200 to achieve a cleaning effect. The scratched stains can be discharged together with the water flow inside the water tub 100. The plastic protrusion structure on the cleaning cloth 401 can be a hemispherical structure. Example 2

[0031] On the basis of the first embodiment, the positions of the main ring 410 and the secondary ring 420 can be adjusted by providing the moving mechanism 300 .

[0032] like Figure 3-Figure 4 As shown, in this embodiment, the moving mechanism 300 includes:

[0033] Two U-shaped plates 310, two winding drums 320 and two pressure plates 330, the two arms of the two U-shaped plates 310 are fixedly connected to the top surface of the water-blocking ring 110, the two winding drums 320 are respectively rotatably connected between the two arms of the two U-shaped plates 310, the outer walls of the two winding drums 320 are fixedly wrapped with pull ropes 321, and one end of the two pull ropes 321 passes through the bottom surface of the water-blocking ring 110, one end of the two pull ropes 321 is fixedly connected to the top surface of the main ring 410, the two pressure plates 330 are respectively slidably clamped between the two arms of the two U-shaped plates 310, and the top surfaces of the two pressure plates 330 are rotatably connected with screw bolts, the top surfaces of the two U-shaped plates 310 are provided with threaded holes, and the two screw bolts are respectively screwed into the two threaded holes.

[0034] During specific implementation, the positions of the main ring 410 and the secondary ring 420 are adjusted by rotating the two winding drums 320 to retract and release the pull ropes 321. Due to their own weight, the main ring 410 and the secondary ring 420 will always straighten the two pull ropes 321. Since the cleaning cloth 401 has a raised structure made of plastic on the other side, it is in direct contact with the water tub 100 and the washing tub 200, so that the contact area of ​​the cleaning cloth 401 with the inner walls of the water tub 100 and the washing tub 200 is small, which facilitates the main ring 410 and the secondary ring 420 to slide naturally between the inner and outer drums due to their own weight. After adjusting the positions of the main ring 410 and the secondary ring 420, the screw bolts can be rotated to make the two pressure plates 330 press the ends of the adjacent winding drums 320 to fix the two winding drums 320, thereby fixing the positions of the main ring 410 and the secondary ring 420. The pressure plates 330 and the ends of the winding drum 320 are coated with abrasive material to increase friction.

[0035] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.

[0036] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
