Description

Technical Field

[0001] This utility model mainly relates to the field of washing machine inner tubs, specifically to an impact-resistant and reinforced washing machine inner tub assembly. Background Technology

[0002] As an essential appliance in modern households, the core working component of a washing machine is the inner tub assembly. The inner tub assembly typically includes an inner tub with numerous drain holes along its circumference, and an inner tub base (or flange) coaxially connected to it for transmission. During operation, especially during the high-speed spin-drying phase, the inner tub needs to rotate at speeds of hundreds or even thousands of revolutions per minute. Under these high-speed conditions, the distribution of clothes inside the tub inevitably becomes uneven, resulting in significant centrifugal force impact and dynamic unbalanced loads on the inner tub assembly.

[0003] During the operation of specific embodiments, the inventors discovered the following defects:

[0004] Traditional reinforcing ribs are usually designed as simple straight strips or arc-shaped protrusions. When they are connected to the barrel wall or bottom, the root area is prone to stress concentration when subjected to repeated impacts, which can become the origin of fatigue cracks and pose a risk of cracking under long-term use.

[0005] It should be noted that the above content falls within the scope of the inventor's technical knowledge. Due to the vast and complex nature of the technical content in this field, the above content of this application does not necessarily constitute prior art. Utility Model Content

[0028] Example

[0029] See attached document Figure 1-3An impact-resistant and reinforced washing machine inner drum assembly includes a washing machine inner drum structure 1, and a side support structure 2 is provided on the outer wall of the washing machine inner drum structure 1. The number of side support structures 2 is set to multiple, and the multiple side support structures 2 are arranged in a ring array on the outer wall of the washing machine inner drum structure 1.

[0030] The side support structure 2 includes a clamping structure and a fixing structure. The clamping structure is disposed at the top and bottom of the inner drum structure 1 of the washing machine. A fixing structure is disposed between the two clamping structures and is disposed on the inner wall of the machine compartment.

[0031] Furthermore, the washing machine inner drum structure 1 includes a washing machine inner drum body 101. The inner drum body 101 has a water outlet groove 102 inside. The top and bottom of the outer wall of the inner drum body 101 are provided with mounting rings 103. The outer wall of the mounting rings 103 has a mounting groove 104. When the inner drum body 101 rotates, water is discharged through the water outlet groove 102. At the same time, the mounting groove 104 rotates on the outer wall of the rolling ball 203. During the rotation of the inner drum body 101, the inner drum body 101 will pass through the cleaning strip 206. The cleaning strip 206 can clean the impurities attached to the inner drum body 101.

[0032] Furthermore, the clamping structure includes a mounting plate 201, with a sliding ring 202 slidably connected to the inner wall of the mounting groove 104. A rolling ball 203 is rotatably connected inside the sliding ring 202. A cleaning strip 206 is provided on the inner side of the mounting plate 201. Sliding holes 204 are provided on both sides of the mounting plate 201, and a mating hole 205 is provided in the middle of the mounting plate 201. A bidirectional lead screw 207 is provided between the two mounting plates 201, with sealing rings 208 at both ends of the bidirectional lead screw 207. The bidirectional lead screw 207 and the mating hole 204 are connected. 5. The fixed structure includes a mounting block 209, a side plate 210 on the outer wall of the mounting block 209, the side plate 210 being connected to the machine compartment, a positioning hole 211 in the middle of the mounting block 209, the positioning hole 211 being rotatably connected to a two-way lead screw 207, and sliding rods 212 on the top and bottom of the mounting block 209, the sliding rods 212 being slidably connected to sliding holes 204. When it is necessary to install the inner drum structure 1 of the washing machine, the mounting block 209 is installed onto the inner wall of the washing machine through the side plate 210, and then the inner drum structure 1 of the washing machine is installed into the side support structure 2.

[0033] Align the mounting groove 104 with the mounting plate 201, manually rotate the double-acting screw 207, the double-acting screw 207 drives the mounting plate 201 to move inward through the mating hole 205, and then the sliding hole 204 inside the mounting plate 201 slides on the outer wall of the sliding rod 212, so that the rolling ball 203 inside the sliding ring 202 on the inner side of the mounting plate 201 contacts the mounting groove 104, thereby completing the fixation of the inner drum body 101 of the washing machine, improving the stability of the inner drum body 101 during the rotation process, and improving the impact resistance of the inner drum body 101 of the washing machine.

[0034] Installation and fixing structure:

[0035] The mounting block 209 is fixed to the inner wall of the washing machine compartment via the side plate 210.

[0036] Ensure that the slide bar 212 and positioning hole 211 on the mounting block 209 are facing correctly.

[0037] Install the inner drum structure of the washing machine:

[0038] The inner drum structure 1 of the washing machine is placed between multiple side support structures 2.

[0039] Ensure that the mounting groove 104 on the mounting ring 103 is aligned with the mounting plate 201.

[0040] Clamping structure operation:

[0041] Manually rotate the bidirectional lead screw 207, which drives the upper and lower mounting plates 201 to move towards each other through the mating hole 205.

[0042] The mounting plate 201 slides along the slide bar 212, pushing the sliding ring 202 and the rolling ball 203 inside it into contact with the mounting groove 104.

[0043] The rolling ball 203 reduces friction, allowing the inner cylinder to rotate freely, while the clamping structure provides stable support.

[0044] Operation process:

[0045] When the inner drum of the washing machine rotates, water is discharged through the drain tray 102.

[0046] Cleaning strip 206 continuously cleans the outer wall of the inner cylinder to prevent the accumulation of impurities.

[0047] The side support structure disperses stress, avoids stress concentration, and improves impact resistance.

[0048] The above-described embodiments are merely illustrative of certain implementations of this utility model, and their descriptions are relatively specific and detailed. However, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
