[0044] See also Figures 1-9 As shown, a drum washing machine inner drum tripod of this embodiment includes:

[0045] Connecting sleeve 400;

[0046] At least three support arms 200 are individually machined and formed;

[0047] A radially extending positioning groove 403 is provided on the outer peripheral wall of the connecting sleeve 400, and the positioning groove 403 is arranged corresponding to the support arm 200. Each of the support arms 200 is pre-positioned and matched with the positioning groove 403 of the connecting sleeve 400 and then welded to form an integrated structure. Each of the support arms 200 is evenly distributed along the outer peripheral wall of the connecting sleeve 400.

[0048] In the drum washing machine inner drum tripod of this embodiment, the connecting sleeve 400 and the at least three support arms 200 can be separately processed and formed. The at least three support arms 200 are welded and fixed to the connecting sleeve 400 to form an integrated structure, which has the following technical effects:

[0049] First, the connecting sleeve 400 and the support arm 200 are processed separately. Compared with the existing one-piece die-casting method, the requirements for processing equipment are lower and the processing method is simpler and more flexible.

[0050] Secondly, a positioning groove 403 is provided on the outer periphery of the connecting sleeve 400 to cooperate with the support arm 200 for positioning, thereby improving the positioning effect.

[0051] Again, the processed connecting sleeve 400 and the support arm 200 are fixedly connected into an integral structure by welding. Compared with the existing integral die-casting method, the process is simple and reliable, and meets the overall rigidity requirements of the inner drum tripod of the drum washing machine.

[0052] Finally, the above-described method reduces the overall cost of the drum tripod of the drum washing machine of this embodiment. Even if corrosion or fracture occurs and replacement is required during long-term use, the user's repair and replacement costs can be reduced. Furthermore, if the connecting sleeve 400 or the support arm 200 can be replaced separately, the user's repair and replacement costs can be further reduced.

[0053] In summary, the inner drum tripod of a drum washing machine of this embodiment reduces the production cost and can simultaneously meet the rigidity requirements of the entire tripod, thus having broad market value.

[0054] As an optional implementation of this embodiment, see Figures 1-4 As shown, the support arm 200 described in this embodiment has a horizontal arm section 202 and a first vertical arm section 203 and a second vertical arm section 204 respectively connected to the two ends of the horizontal arm section 202, and one end of the first vertical arm section 203 and one end of the second vertical arm section 204 are respectively pre-positioned with the positioning groove 403 of the connecting shaft sleeve 400 and then welded to form an integrated structure.

[0055] The support arms 200 of this embodiment are processed and manufactured separately, and then the support arms 200 are welded and fixed to the connecting sleeves 400 to form an integrated structure. Before welding, the support arms 200 and the connecting sleeves 400 are pre-positioned and matched through the positioning grooves 403 to facilitate welding and fixing between each support arm 200 and the connecting sleeve 400.

[0056] See also Figure 1 、 Figure 5-Figure 7 As shown, a drum washing machine inner drum tripod of this embodiment includes an inner drum shaft 100, one end of the inner drum shaft 100 is inserted into the connecting shaft sleeve 400 and fixedly connected, a water seal 700 is sleeved on the inner drum shaft 100, and a water seal sealing end cover 500 is fixedly installed on the connecting shaft sleeve 400 near the water seal 700, and the end face of the water seal 700 abuts against the end face of the water seal sealing end cover 500.

[0057] Conventional washing machines use a sealing method where the sealing lip of a water seal 700 seals against the inner shaft 100. This can lead to water leakage over long periods of use, with water seeping into the bearings and inner shaft 100, causing them to rust and seize. The inner drum tripod of this embodiment of a drum washing machine incorporates a new water seal end cap 500. The end face of the water seal 700 forms a sealing contact with the water seal end cap 500, improving the sealing effect of the water seal, thereby enhancing sealing performance and extending its lifespan.

[0058] Furthermore, a sealing sleeve 600 is arranged between the inner cylindrical shaft 100 and the water seal 700. The water seal 700 has a water seal inner lip 701 arranged on the inner circumferential wall and a water seal end face lip 702 arranged on the water seal end face. The water seal inner lip 701 abuts against the outer circumferential wall of the sealing sleeve 600 for sealing, and the water seal end face lip 702 abuts against the end face of the water seal sealing end cover 500 for sealing.

[0059] Optionally, the end face of the water seal end cover 500 of this embodiment has an annular sealing groove, and the water seal end face lip 702 abuts against the annular sealing groove of the water seal end cover 500 for sealing, so as to improve the end face sealing effect between the two.

[0060] See also Figure 1-Figure 7 As shown, the connecting sleeve 400 described in this embodiment includes an integrally formed sleeve body 401, a first shaft segment 402 located at one end of the sleeve body 401, and a second shaft segment 405 located at the other end of the sleeve body 401. The outer diameters of the first shaft segment 402 and the second shaft segment 405 are both smaller than the outer diameter of the sleeve body 401. The intersection of the first shaft segment 402 and the sleeve body 401 forms a first mounting step 404, and the intersection of the second shaft segment 405 and the sleeve body 401 forms a second mounting step. One end of the horizontal arm segment 202 of the support arm 200 is fixed to the first mounting step 404, and the limiter of the water seal end cover 500 is installed on the second mounting step. In this embodiment, the second mounting step is used to achieve pre-positioning of the water seal end cover 500.

[0061] In this embodiment, a first mounting step 404 is constructed on the connecting sleeve 400. When welding the support arm 200, pre-positioning is achieved by overlapping the horizontal arm section 202 of the support arm 200 on the first mounting step 404, which facilitates subsequent welding operations and ensures welding reliability.

[0062] In addition, the support arm 200 of this embodiment is fixed by welding the horizontal arm section 202 to the outer peripheral wall of the first shaft section 402, thereby increasing the stability and reliability of the welding connection between the support arm 200 and the connecting sleeve 400 as much as possible.

[0063] Furthermore, the end surface of the water seal end cap 500 near the support arm 200 of this embodiment contacts and is fixedly connected to each support arm 200. In this embodiment, the water seal end cap 500 and the support arm 200 can be fixed by welding.

[0064] Further preferably, the end portion of the horizontal arm section 202 welded to the outer wall of the first shaft section 402 in this embodiment has an arc-shaped bayonet 201. When the horizontal arm section 202 of the support arm 200 is overlapped on the first mounting step 404 for pre-positioning, when the arc-shaped bayonet 201 tightly fits against the outer wall of the first shaft section 402, the pre-positioning is complete, and welding can now be performed. Moreover, the tight fit between the two further enhances the stability of the welded joint.

[0065] Furthermore, in this embodiment, the end of the first vertical arm section 203 away from the horizontal arm section 202 and the end of the second vertical arm section 204 away from the horizontal arm section 202 are both flanged outward to form a horizontal flange 205. The end of the horizontal flange 205 is flanged upward to form a vertical flange 206. The end of one end of the horizontal flange 205 is tilted so that the end of the vertical flange 206 does not protrude beyond the ends of the first vertical arm section 203 and the second vertical arm section 204. The horizontal flanges 205 of two adjacent support arms 200 are spliced ​​and fixed by welding, and the vertical flanges 206 of two adjacent support arms 200 are spliced ​​and fixed by welding. In this way, the support arms 200 of this embodiment are welded and fixed to the connecting sleeves 400, and the support arms 200 are also welded and fixed to each other, so that the multiple support arms 200 and the connecting sleeves 400 form a whole, ensuring the overall rigidity of the inner drum tripod of the drum washing machine.

[0066] In addition, the above-mentioned structural configuration of the support arm 200 of this embodiment can increase the structural rigidity of the support arm 200 itself and improve the anti-torque capability.

[0067] See also Figure 1-Figure 2 、 Figure 4 、 Figure 8-Figure 9As shown, this embodiment of a drum washing machine inner drum tripod includes an inner drum connection block 300. One end of the support arm 200 is welded to a connecting sleeve 400, and the other end of the support arm 200 is welded to the inner drum connection block 300. The inner drum connection block 300 includes a connecting plate and a weld nut 304, which is welded to the connecting plate. The original inner drum connection block 300 was integrally formed with a flanging threaded hole. This process of stretching the flanging threaded hole resulted in a high flanging height, a complex process, and high processing difficulty. In addition, the wall thickness of the threaded hole after stretching was small, resulting in poor reliability. This embodiment instead welds the nut 304 and the connecting plate together through welding, which facilitates processing and improves reliability.

[0068] Furthermore, the connecting plate body of this embodiment includes an integrally formed horizontal connecting plate body 301 and a vertical connecting plate body 302, a through hole 303 is provided on the vertical connecting plate body 302, and the welding nut 304 is welded and fixed on the vertical connecting plate body 302, and is directly opposite to the through hole 303.

[0069] See also Figure 4 As shown, the vertical flange 206 at the other end of the support arm 200 in this embodiment extends upward and protrudes from the horizontal arm section 202, and the tops of the vertical flanges 206 on both sides of the horizontal arm section 202 are flush with each other, the horizontal connecting plate 301 is welded and fixed to the top of the vertical flange 206, and the vertical connecting plate 302 is welded and fixed to the ends of the horizontal arm section 202, the first vertical arm section 203, the second vertical arm section 204, the horizontal flange 205, and the vertical flange 206, and the welding nut 304 is arranged in the area enclosed by the first vertical arm section 203, the horizontal flange 205, and the vertical flange 206, and / or the area enclosed by the second vertical arm section 204, the horizontal flange 205, and the vertical flange 206.

[0070] In this embodiment of a drum washing machine inner drum tripod, the horizontal connecting piece 301 and the vertical connecting piece 302 of the inner drum connecting block 300 are welded to the ends of the support arm 200 at multiple locations, ensuring an integrated weld between the inner drum connecting block 300 and the support arm 200 and ensuring a secure connection. This embodiment of the drum washing machine inner drum tripod is threadedly connected to the inner drum of the drum washing machine using connecting bolts passing through weld nuts 304.

[0071] Furthermore, the horizontal arm section 202, the first vertical arm section 203, and the second vertical arm section 204 of this embodiment collectively form a first groove 208. The first vertical arm section 203, the horizontal flange 205, and the vertical flange 206 collectively form a second groove 209. The second vertical arm section 204, the horizontal flange 205, and the vertical flange 206 collectively form a third groove 210. The unique structural design of the support arm 200 of this embodiment meets its overall rigidity requirements, the connection stability requirements between the support arm 200 and the connecting sleeve 400, and the connection stability requirements between the support arm 200 and the inner cylinder connecting block 300. Furthermore, the variable overall width of the support arm 200 can reduce the use of alloy raw materials and reduce costs.

[0072] In the inner drum tripod of a drum washing machine of this embodiment, a concave rib 207 is provided on the horizontal arm section 202 to further enhance the strength of the overall support arm 200 .

[0073] This embodiment also provides a drum washing machine having the drum washing machine inner drum tripod, comprising an inner drum, wherein the free end of the support arm of the drum washing machine inner drum tripod is fixedly connected to the bottom of the inner drum.

[0074] The drum washing machine of this embodiment adopts the drum washing machine inner drum tripod to meet the transmission rigidity requirements of the connection between the drive motor and the inner drum, while reducing the cost of the entire machine and the cost of subsequent use and maintenance.

[0075] The above embodiments are only used to illustrate the present invention and are not intended to limit the technical solutions described in the present invention. Although this specification has described the present invention in detail with reference to the above embodiments, the present invention is not limited to the above specific implementation methods.
