Description

Technical Field

[0001] This utility model relates to the field of washing machine accessories technology, specifically to a tripod for the inner drum of a drum washing machine and a drum washing machine. Background Technology

[0002] In the transmission structure of existing drum washing machines: a tripod is fixedly installed on the inner drum assembly. The tripod is installed in the bearing seat of the outer drum of the drum washing machine as a support structure. The motor drives the tripod to rotate, which in turn drives the drum assembly to rotate, so as to realize the washing and spin-drying functions of the washing machine.

[0003] Therefore, as a primary power-bearing component, the tripod bears significant torque over extended periods, requiring high overall rigidity. Consequently, existing tripods are generally manufactured using a single die-cast aluminum alloy piece, which places high demands on die-casting equipment and processes, increasing manufacturing costs. Furthermore, with prolonged use of the washing machine, the working environment makes the tripod susceptible to corrosion and fatigue fracture, further increasing replacement costs.

[0004] Furthermore, the tripod is located inside the outer drum of the drum washing machine. When the washing machine is working, the outer drum acts as a water tank, and the tripod is in constant contact with the washing water. Since the inner drum shaft is not made of stainless steel and has poor corrosion resistance, the inner drum shaft will rust after the connecting bushing of the tripod is assembled with the inner drum shaft.

[0005] In addition, in order to achieve a fixed connection between the tripod and the bottom of the inner drum of the drum washing machine, the end of the tripod's support arm needs to be fixed with an inner drum connecting component. How to design the structure of the inner drum connecting component to ensure the reliability of the connection is also a technical problem that this utility model aims to solve.

[0049] See Figures 1-8 As shown, a tripod for the inner drum of a drum washing machine according to this embodiment includes:

[0050] The connecting bushing 400 has a hollow channel inside, and the connecting bushing 400 has a first end 405 and a second end 402 opposite to each other.

[0051] At least three support arms 200 are individually machined and formed. Each support arm 200 is pre-positioned and welded to the outer peripheral wall of the connecting bushing 400 to form an integral structure. Each support arm 200 is evenly distributed along the outer periphery of the connecting bushing 400.

[0052] The inner cylinder shaft 100 is inserted and fixedly assembled at one end by the first end 405 of the connecting bushing 400;

[0059] In summary, the drum washing machine inner drum tripod of this embodiment reduces manufacturing costs and can simultaneously meet the rigidity requirements of the tripod as a whole, thus possessing broad market value.

[0060] In addition, in this embodiment, a tripod for the inner drum of a drum washing machine is provided. A sealing cover 500 is used to seal the second end 402 of the connecting shaft sleeve 400, thereby sealing the hollow channel of the connecting shaft sleeve 400 and preventing washing water from entering between the connecting shaft sleeve 400 and the inner drum shaft 100, which would cause the inner drum shaft 100 to rust and corrode.

[0061] To achieve the sealing cap 500 covering the second end 402 of the connecting bushing 400, this embodiment adopts the following two implementation schemes:

[0062] In the first specific implementation of the technical solution, the inner wall of the second end 402 of the connecting bushing 400 in this embodiment has a limiting step, and the sealing cover 500 is installed in the hollow channel of the second end 402 of the connecting bushing 400 and is limited and stopped by the limiting step.

[0063] The first specific implementation technical solution is to achieve the sealing and limiting installation of the sealing cover 500 by setting a limiting step in the hollow channel inside the second end 402 of the connecting bushing 400.

[0064] In the second specific implementation of the technical solution, the sealing cover 500 in this embodiment includes an integrally formed sealing cover body and a sealing plug body. A limiting boss is formed between the sealing cover body and the sealing plug body. The sealing plug body is installed in the hollow channel of the second end 402 of the connecting bushing 400 and is limited and stopped by the limiting boss.

[0065] The second specific implementation scheme does not require structural design for the connecting bushing 400; a sealing connection can be achieved by using a sealing cover 500 that can be matched with it.

[0066] Furthermore, in this embodiment, a drum washing machine inner drum tripod includes an inner drum connecting block 300. One end of the support arm 200 is welded and fixed to the connecting bushing 400, and the other end of the support arm 200 is welded and fixed to the inner drum connecting block 300. The inner drum connecting block 300 includes a connecting body and a connecting nut 302. The connecting nut 302 is welded inside the connecting body. The connecting body has an open mounting cavity at one end. The connecting nut 302 is welded to the bottom wall of the mounting cavity inside the connecting body. The open end of the mounting cavity of the connecting body is fitted onto the other end of the support arm 200 and welded and fixed.

[0067] In this embodiment, the inner cylinder connecting block 300 is constructed by welding the connecting body and the connecting nut 302 together, which is convenient to process and has good reliability. Moreover, the connecting body in this embodiment has an open mounting cavity at one end. The open end of the mounting cavity of the connecting body is fitted onto the other end of the support arm 200 and welded to fix it. In this way, the connecting body can completely cover the other end of the support arm 200, ensuring the stability and reliability of the weld between the connecting body and the other end of the support arm 200.

[0068] Specifically, the connecting body described in this embodiment includes a main connecting piece 301 and a connecting flange integrally disposed on the outer periphery of the main connecting piece 301. The connecting flange is bent toward one side of the main connecting piece 301, together forming an open mounting cavity.

[0069] In this embodiment, the second end 402 of the connecting bushing has a mounting step 404; the support arm 200 has a horizontal arm segment 202 and a first vertical arm segment 203 and a second vertical arm segment 204 respectively connected to both ends of the horizontal arm segment 202. One end of the horizontal arm segment 202 is disposed on the mounting step 404 and welded to the outer peripheral wall of the second end 402. One end of the first vertical arm segment 203 and one end of the second vertical arm segment 204 are respectively welded to the outer peripheral wall of the connecting bushing 400; the first vertical arm segment 203 is located away from the horizontal arm segment 202. One end of 02 and the other end of the second vertical arm segment 204 away from the horizontal arm segment 202 are both turned outward to form a horizontal flange 205. The end of the horizontal flange 205 is turned upward to form a vertical flange 206. The end of one end of the horizontal flange 205 is inclined so that the end of the vertical flange 206 does not protrude from the ends of the first vertical arm segment 203 and the second vertical arm segment 204. The horizontal flanges 205 of two adjacent support arms 200 are spliced ​​together and fixed by welding. The vertical flanges 206 of two adjacent support arms 200 are spliced ​​together and fixed by welding.

[0070] In this embodiment, the horizontal arm segment 202, the first vertical arm segment 203, and the second vertical arm segment 204 together form a first groove 208. The first vertical arm segment 203, the horizontal flange 205, and the vertical flange 206 together form a second groove 209. The second vertical arm segment 204, the horizontal flange 205, and the vertical flange 206 together form a third groove 210. The unique structural design of the support arm 200 in this embodiment meets its overall rigidity requirements, the connection stability requirements between the support arm 200 and the connecting bushing 400, and the connection stability requirements between the support arm 200 and the inner cylinder connecting block 300. At the same time, the variation in the overall width of the support arm 200 can reduce the use of alloy raw materials and lower costs.

[0071] Correspondingly, in this embodiment, the horizontal arm segment 202 of the support arm 200 away from the connecting bushing 400 is flush with the top of the vertical flanges 206 on both sides. The open end of the mounting cavity of the connecting body is fitted onto the other end of the support arm 200, covering the horizontal flange 205, vertical flange 206 and horizontal arm segment 202 of the support arm 200 away from the connecting bushing 400.

[0072] For a specific implementation of this embodiment, see Figure 6 and Figure 7 As shown, the connecting flanges in this embodiment include two first connecting flanges 303 and a second connecting flange 304 arranged opposite to each other, and two third connecting flanges 305 arranged opposite to each other. The open end of the mounting cavity of the connecting body is fitted onto the other end of the support arm 200. The inner wall of the first connecting flange 303 is attached to and welded to the top of the horizontal arm segment 202 on the support arm 200 away from the connecting bushing 400 and the vertical flanges 206 on both sides of the horizontal arm segment 202. The second connecting flange 304 is attached to and welded to the bottom of the horizontal flange 205 on the support arm 200 away from the connecting bushing 400. The third connecting flange 305 is attached to and welded to the outer wall of the vertical flanges 206 on both sides of the horizontal arm segment 202 on the support arm 200 away from the connecting bushing 400.

[0073] Furthermore, in this embodiment, the horizontal arm segment 202 of the support arm 200 away from the connecting bushing 400 has a limiting step 211, which is used to limit the opening end of the mounting cavity of the connecting body to be fitted onto the other end of the support arm 200.

In this embodiment, the inner drum connecting piece 300' is integrally formed, and the connecting threaded hole 306 is machined simultaneously, resulting in better precision and product consistency.

[0075] To ensure the strength of the inner cylinder connecting piece 300', the inner cylinder connecting piece 300' in this embodiment has a certain thickness and is formed by extrusion of a metal block.

[0076] This embodiment also provides a drum washing machine with the aforementioned drum washing machine inner drum tripod, including an inner drum, wherein the free end of the support arm 200 of the drum washing machine inner drum tripod is fixedly connected to the bottom of the inner drum.
