Description

Technical Field

[0001] This invention belongs to the field of washing machine technology, specifically a conical spin-drying tub installation device for a washing machine. Background Technology

[0002] A spin-drying drum is a device that uses centrifugal force to achieve dehydration. This device is responsible for the dehydration function in a washing machine. It separates water by rotating at high speed. When its outer cover is closed, it triggers the brake device to release. To improve safety, some models are equipped with a spin-drying cap and a closing protection device.

[0003] In the prior art, a shock-absorbing structure for a washing machine spin-dry tub, with publication number CN222648382U, utilizes the elastic absorption of an elastic damper to resist the eccentric force of the spin-dry tub, thereby returning the center of gravity of the spin-dry tub to its central axis. This allows the spin-dry tub to quickly enter high-speed rotation, and the elastic damper can quickly recover after deformation. Furthermore, it exhibits low noise and causes minimal damage to the washing machine body, drive mechanism, and transmission shaft, extending the washing machine's lifespan. However, it still has the following problems: When the aforementioned spin dryer is in use, the elastic damping body absorbs the eccentric force of the spin dryer, allowing it to quickly enter high-speed rotation. However, the spin dryer is fixed to the drive assembly with several bolts during use, making disassembly, repair, and cleaning quite troublesome.

[0004] Therefore, a conical spin-drying drum installation device for washing machines is proposed to address the above problems. Summary of the Invention

[0008] Preferably, the inner wall of the cylinder is fixedly connected to the front, back, left, and right sides with first ribs, and the side walls of the cylinder are provided with a number of drainage holes.

[0009] Preferably, the bottom of the spin dryer is provided with a support mechanism, the support mechanism includes a support partition, and the top of the support partition is fixedly connected with a second rib on all four sides (front, back, left, and right).

Hydraulic dampers are hinged to the front, back, left, and right sides of the top of the shock-absorbing disc, and the output end of each hydraulic damper is respectively hinged to the front, back, left, and right sides of the bottom of the mounting base.

[0012] Preferably, the top of the spin-drying drum is connected to four suspension springs on all four sides, and each suspension spring is connected to a guide ring. The spin-drying drum is elastically connected to the guide rings through the suspension springs, and the guide rings are slidably connected to the fixed cylinder.

[0013] Preferably, the bottom of the shock absorption mechanism is provided with a drive mechanism, the drive mechanism includes a drive motor, and the output end of the drive motor is fixedly connected to a drive shaft.

[0014] Preferably, the drive shaft is externally fixedly connected to a bearing seat, and the bearing seat is threaded with first bolts on all four sides (front, back, left, and right). The bearing seat is fixedly connected to the shock absorber plate by the first bolts.

[0016] (III) Beneficial Effects Compared with the prior art, the present invention provides a conical spin-dry tub mounting device for a washing machine, which has the following advantages: 1.

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Specific implementation examples are given below.

[0024] Please see Figures 1-8 The present invention provides a conical spin-dry tub installation device for a washing machine, including a fixed cylinder 1, a spin-dry tub 2 located inside the fixed cylinder 1, and an installation mechanism 4 located at the bottom of the spin-dry tub 2. A support mechanism 3 is provided at the bottom of the spin-dry tub 2, a shock-absorbing mechanism 5 is provided at the bottom of the installation mechanism 4, a drive mechanism 6 is provided at the bottom of the shock-absorbing mechanism 5, and a balancing mechanism 7 is provided at the top of the spin-dry tub 2.

[0025] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 7 and Figure 8As shown, the spin dryer 2 includes a cylinder 201. A mounting plate 204 is fixedly connected to the bottom of the cylinder 201. Mounting grooves 205 are provided on the front, back, left, and right sides of the mounting plate 204. The mounting mechanism 4 includes a mounting base 401. A mounting ring groove 402 is provided on the top of the mounting base 401. Mounting blocks 403 are slidably connected to the front, back, left, and right sides of the mounting ring groove 402. A movable screw 404 is movably connected to the side of each mounting block 403 near the center of the mounting base 401. A limiting ball groove is provided on the top of each mounting block 403. A limiting ball 405 is fitted inside each limiting ball groove. A limiting rod 406 is fixedly connected to the top of each limiting ball 405. A limiting sleeve block 407 is sleeved on the outside of the limiting rod 406. A metal piece 408 is provided above the limiting sleeve block 407. The metal piece 408 is fixedly connected to the mounting base 401. The limiting rod 406 is slidably connected to the mounting base 401.

[0026] The above method involves inserting the mounting plate 204 into the mounting ring groove 402, rotating the movable screw 404, and pushing the mounting insert 403 into the mounting groove 205 under the action of the thread. Since a metal plate 408 is provided above the limiting sleeve 407, under the elastic force of the metal plate 408 and the action of the limiting sleeve 407, the limiting rod 406 is pushed to drive the limiting ball 405 into the limiting ball groove, thus completing the fixed installation of the spin dryer 2.

[0027] like Figure 1 , Figure 2 , Figure 3 and Figure 6 As shown, the inner wall of the cylinder 201 is fixedly connected to the four sides of the front, back, left and right sides with first ribs 202. The side walls of the cylinder 201 are provided with a number of drainage holes 203. The bottom of the spin dryer 2 is provided with a support mechanism 3. The support mechanism 3 includes a support partition 301. The top of the support partition 301 is fixedly connected to the four sides of the front, back, left and right sides with second ribs 302. The side walls of the support partition 301 are provided with fixed insertion holes 303. Each fixed insertion hole 303 is slidably connected to a fixed insertion rod 304. Each fixed insertion rod 304 is fixedly connected to the top with a push rod 305. Each fixed insertion rod 304 is connected to a fixed spring 306 on the side away from the center of the support partition 301. The fixed insertion rod 304 is elastically connected to the cylinder 201 through the fixed spring 306.

[0028] Through the above scheme: pulling the push rod 305 moves the four fixed insertion rods 304 away, placing the support partition 301 at the bottom of the cylinder 201. Since the fixed insertion rod 304 is elastically connected to the cylinder 201 through the fixed spring 306, under the elastic force of the fixed spring 306, the fixed insertion rod 304 is pushed into the fixed insertion hole 303, thus completing the installation and fixing of the support partition 301.

[0029] like Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, the shock absorption mechanism 5 includes a shock absorption disc 501. Hydraulic dampers 502 are hinged to the front, back, left, and right sides of the top of the shock absorption disc 501. The output end of each hydraulic damper 502 is hinged to the front, back, left, and right sides of the bottom of the mounting base 401. Suspension springs 503 are connected to the front, back, left, and right sides of the top of the spin-drying drum 2. A guide ring 504 is connected to the outside of each suspension spring 503. The spin-drying drum 2 is elastically connected to the guide ring 504 through the suspension springs 503. The guide ring 504 is slidably connected to the fixed cylinder 1.

[0030] The above solution works as follows: when subjected to vibration, the energy generated compresses the damper. The damper, with its high recovery damping characteristics, dissipates the high-frequency vibration energy generated by the slight uneven distribution of clothes, preventing the vibration from being transmitted to the outer shell and ensuring the smooth operation of the washing machine. At the same time, the suspension spring 503 provides support and vibration isolation for the spin-drying tub 2.

[0031] like Figure 1 , Figure 2 and Figure 4 As shown, the drive mechanism 6 includes a drive motor 601, the output end of the drive motor 601 is fixedly connected to a drive shaft 602, the drive shaft 602 is fixedly connected to a bearing seat 603, and the bearing seat 603 is threaded with first bolts 604 on all four sides (front, back, left, and right). The bearing seat 603 is fixedly connected to the shock absorber 501 through the first bolts 604.

[0032] Through the above scheme: the drive motor 601 starts, driving the drive shaft 602 to rotate, and under the action of the bearing seat 603, it drives the spin-drying drum 2 to rotate, and performs spin-drying and dehydration treatment.

[0033] like Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, the balancing mechanism 7 includes a balancing ring 701. The balancing ring 701 is threaded with second bolts 702 on all four sides (front, back, left, and right). The balancing ring 701 is fixedly connected to the cylinder 201 by the second bolts 702.

[0034] The above method involves inserting the balance ring 701 into the top of the spin dryer 2 and using the second bolt 702 to install and fix the balance ring 701 to the spin dryer 2.

[0035] Working principle: In actual use, first, insert the mounting plate 204 into the mounting ring groove 402, and push the mounting plug 403 into the mounting groove 205 by rotating the movable screw 404. Then, use the elastic force of the metal plate 408 to push the limit rod 406 to drive the limit ball 405 into the limit ball groove, thus completing the fixed installation of the spin dryer 2.

[0036] Next, by pulling the push rod 305, the four fixed insert rods 304 on all sides are moved away, and the support partition 301 is placed at the bottom of the cylinder 201. The spring force of the fixed spring 306 is used to push the fixed insert rod 304 into the fixed insert hole 303 to complete the installation and fixation of the support partition 301. The balance ring 701 is inserted into the top of the spin dryer 2, and the balance ring 701 is installed and fixed to the spin dryer 2 by the second bolt 702.

[0037] Finally, the drive motor 601 drives the drive shaft 602 to rotate, and under the action of the bearing seat 603, it drives the spin-drying tub 2 to rotate for spin-drying and dehydration. When subjected to vibration, the energy generated compresses the damper. The damper uses its high recovery damping characteristics to dissipate the high-frequency vibration energy generated by the slight uneven distribution of clothes, preventing the vibration from being transmitted to the outer shell and ensuring the smooth operation of the washing machine. At the same time, the suspension spring 503 provides support and vibration isolation for the spin-drying tub 2.

[0038] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed invention.
