Description

Technical Field

[0001] The utility model relates to the field of anti-collision structures, and particularly to a washing machine shell with an internal anti-collision structure. Background Art

[0002] The washing machine, as an indispensable cleaning appliance in modern families, skillfully applies the principle of converting electrical energy into mechanical energy to achieve efficient cleaning and convenient care of clothes.

[0003] Currently, most existing washing machines are driven by an internal motor. For example, a drum washing machine drives the drum to rotate through the motor, generating strong water flow and friction to penetrate into the clothing fibers, effectively removing stains, oil stains, and dust and odors accumulated during daily wear, greatly improving the convenience and comfort of family life.

[0004] However, this drum washing machine still has certain problems. For example, during its operation, when the motor drives the drum to rotate, due to the uneven placement of clothes in the drum, when the motor drives the drum to rotate and drives the water flow and clothes to perform centrifugal motion, uneven centrifugal force will be generated, causing the drum to shake violently. At the same time, the drum will hit the washing machine shell, resulting in physical damage to the washing machine shell, and even structural damage. It may also affect the precision and durability of the internal components of the washing machine, and in the long run, it will shorten the service life of the washing machine. Summary of the Utility Model

[0005] Based on this, the purpose of the utility model is to provide a washing machine shell with an internal anti-collision structure to solve the technical problems mentioned in the above background art.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A washing machine shell with an internal anti-collision structure, including a washing machine shell and a drum. The washing machine shell includes a base, a housing, and an anti-collision device. The housing is sleeved on the top of the base. Multiple anti-collision devices are installed inside the washing machine shell. The anti-collision device includes an anti-collision base, a sliding rod, a sliding block, a buffer plate, and a damping rod. The anti-collision base is installed inside the washing machine shell, and a sliding rod is installed on the inner wall of the anti-collision base. A sliding block is slidably installed on the outer wall of the sliding rod, and a damping rod is fixedly installed on the outer wall of the sliding rod. A buffer plate corresponding to the drum is fixedly installed on the outer wall of the sliding block.

[0007] By adopting the above technical solution, when the drum rotates and hits the anti-collision device, the buffer plate of the anti-collision device will absorb the impact force and stretch to both sides. At the same time, the damping rod of the anti-collision device will absorb the impact force and contract. When the buffer plate stretches, the remaining impact force will be conducted to the anti-collision base through the sliding rod, thereby greatly reducing the impact force.

[0008] Further, the anti-collision device further includes a buffer wheel, and the buffer wheel is rotatably installed on the outer wall of the buffer plate.

[0009] By adopting the above technical solution, when the drum rotates and contacts the anti-collision device, the buffer wheel can reduce the friction between the drum and the anti-collision device.

[0010] Furthermore, the anti-collision device further includes fixed rods, telescopic rods and springs. Multiple groups of fixed rods are fixedly installed on the outer wall of the slider. The two ends of the telescopic rod are respectively fixedly connected to the ends of the corresponding fixed rods, and a spring is sleeved on the outer wall of the telescopic rod, and both ends of the spring are fixedly connected to the ends of the corresponding fixed rods.

[0011] By adopting the above technical solution, the telescopic rod can limit the spring, and part of the impact force can be conducted to the spring through the fixed rod, and the spring can help the anti-collision device to reset.

[0012] Furthermore, the washing machine housing further includes corner fixing blocks. The corner fixing blocks are fixedly installed at the corners of the top end of the base, and the corner fixing blocks are designed as quarter circles, and anti-collision devices are fixedly connected between multiple groups of corner fixing blocks.

[0013] By adopting the above technical solution, the impact force received can be released to the base, and the corner fixing blocks can support the anti-collision device.

[0014] Furthermore, the sliding rod penetrates through multiple groups of sliders, and both ends of the buffer plate are respectively fixedly connected to the outer walls of the corresponding sliders, and the buffer plate is an elastic plate member.

[0015] By adopting the above technical solution, the sliding rod can limit the sliders, and when the buffer plate is stressed, it can drive the sliders to slide so as to conduct the impact force to the anti-collision base, and the buffer plate can absorb the impact force and is convenient for resetting.

[0016] Furthermore, the bottom end of the damping rod is fixedly connected to the outer wall of the sliding rod, and the top end of the damping rod is in contact with the buffer plate.

[0017] By adopting the above technical solution, part of the impact force can be absorbed, and at the same time, the buffer plate is limited, so that the conduction of the impact force by the buffer plate is more uniform.

[0018] Furthermore, the anti-collision base is designed in a concave shape, and both ends of the sliding rod are respectively fixedly connected to the inner walls of the corresponding anti-collision bases.

[0019] By adopting the above technical solution, support can be provided for the sliding rod, and the impact force can be absorbed by the protrusions on both sides of the concave design and conducted to the base.

[0020] Furthermore, multiple groups of buffer wheels are equidistantly installed on the outer wall of the buffer plate, and when the drum rotates and collides with the anti-collision device, the buffer wheels rotatably connected to the outer walls of the drum and the buffer plate come into contact.

[0021] By adopting the above technical solution, the friction between the roller and the buffer wheel can be further reduced.

[0022] In summary, the main beneficial effects of the present utility model are as follows:

[0023] The present utility model is provided with a bumper installed between the corner fixing blocks. When the roller rotates and hits the bumper, the buffer plate of the bumper will absorb the impact force and stretch to both sides. At the same time, the damping rod of the bumper will absorb the impact force and contract, and the spring of the bumper will also absorb the force and stretch. When the buffer plate stretches, the remaining impact force will be conducted to the anti-collision base, thereby greatly reducing the impact force. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0029] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. The embodiments described below by referring to the drawings are exemplary and are only used to explain the present utility model and should not be construed as limiting the present utility model.

[0030] The following will describe the embodiments according to the overall structure of the present utility model.

[0031] A washing machine housing with a built-in anti-collision structure, such as Figure 1 - Figure 4As shown in the figure, it includes a washing machine housing 1 and a drum 3. The washing machine housing 1 includes a base 5, an outer shell 6 and a bumper 4. The outer shell 6 is sleeved on the top of the base 5. Multiple groups of bumpers 4 are installed inside the washing machine housing 1, which can prevent collisions with the drum 3 from multiple directions. The bumper 4 includes a bumper base 401, a slide bar 402, a slider 403, a buffer plate 404 and a damping rod 406. The bumper base 401 is installed inside the washing machine housing 1, so that when the drum 3 collides with the bumper 4, it will not damage the outer shell 6. A slide bar 402 is installed on the inner wall of the bumper base 401, and a slider 403 is slidably installed on the outer wall of the slide bar 402. The slider 403 can conduct the impact force by sliding on the slide bar 402. A damping rod 406 is fixedly installed on the outer wall of the slide bar 402, and the damping rod 406 plays a role in limiting and unloading the force to a certain extent. A buffer plate 404 corresponding to the drum 3 is fixedly installed on the outer wall of the slider 403. When the buffer plate 404 is hit by the drum 3, the impact force will be evenly transmitted to the bumper base 401 through the slide bar 402.

[0032] Please refer to Figure 1 、 Figure 2 and Figure 4 , the bumper 4 further includes a buffer wheel 405. The buffer wheel 405 is rotatably installed on the outer wall of the buffer plate 404. When the drum 3 rotates and contacts the bumper 4, the buffer wheel 405 can reduce the friction between the drum 3 and the bumper 4.

[0033] Please refer to Figure 1 and Figure 4 , the bumper 4 further includes a fixed rod 407, a telescopic rod 408 and a spring 409. Multiple groups of fixed rods 407 are fixedly installed on the outer wall of the slider 403. The two ends of the telescopic rod 408 are respectively fixedly connected to the ends of the corresponding fixed rods 407. A spring 409 is sleeved on the outer wall of the telescopic rod 408, so that the telescopic rod 408 can limit the spring 409. Both ends of the spring 409 are fixedly connected to the ends of the corresponding fixed rods 407, so that a part of the impact force can be conducted to the spring 409 through the fixed rod 407, and the spring 409 can help the bumper 4 to reset.

[0034] Please refer to Figure 1 - Figure 3 , the washing machine housing 1 further includes corner fixing blocks 2. The corner fixing blocks 2 are fixedly installed at the corners of the top of the base 5, and can release the received impact force to the base 5. The corner fixing blocks 2 are designed as a quarter circle, and multiple groups of corner fixing blocks 2 are fixedly connected to the bumper 4, so that the corner fixing blocks 2 can support the bumper 4.

[0035] Please refer to Figure 1 、 Figure 2 and Figure 4, the slide bar 402 passes through multiple groups of sliders 403, enabling the slide bar 402 to limit the sliders 403. Both ends of the buffer plate 404 are fixedly connected to the outer walls of the corresponding sliders 403, so that when the buffer plate 404 is stressed, it can drive the sliders 403 to slide, thereby transmitting the impact force to the anti-collision base 401. Moreover, the buffer plate 404 is an elastic plate member, which can absorb the impact force and facilitate resetting.

[0036] Please refer to Figure 1 、 Figure 2 and Figure 4 , the bottom end of the damping rod 406 is fixedly connected to the outer wall of the slide bar 402, and the top end of the damping rod 406 is in contact with the buffer plate 404, which can absorb part of the impact force and limit the buffer plate 404 at the same time, making the transmission of the impact force by the buffer plate 404 more uniform.

[0037] Please refer to Figure 1 、 Figure 2 and Figure 4 , the anti-collision base 401 is designed in a concave shape, and both ends of the slide bar 402 are fixedly connected to the inner walls of the corresponding anti-collision bases 401, which can provide support for the slide bar 402. The two protrusions on both sides of the concave design absorb the impact force and transmit it to the base 5.

[0038] Please refer to Figure 1 、 Figure 2 and Figure 4 , multiple groups of buffer wheels 405 are equidistantly installed on the outer wall of the buffer plate 404. When the roller 3 rotates and collides with the anti-collision device 4, the outer wall of the roller 3 contacts the buffer wheels 405 rotatably connected to the outer wall of the buffer plate 404, which can further reduce the friction between the roller 3 and the buffer wheels 405.

[0039] The working principle of the present utility model is as follows: When in use, the power is turned on, and the motor drives the roller 3 to start rotating. When the roller 3 rotates, it will generate shaking. Since angle fixing blocks 2 are fixedly installed at the corners of the anti-collision base 401, and anti-collision devices 4 are fixedly installed between the angle fixing blocks 2. When the roller 3 shakes and impacts the anti-collision device 4, the outer wall of the roller 3 will first contact the buffer wheel 405 of the anti-collision device 4. Since the buffer wheel 405 is rotatably installed on the outer wall of the buffer plate 404, and the roller 3 is in a rotating state when it impacts, the buffer wheel 405 will reduce the friction between the roller 3 and the anti-collision device 4. At this time, the roller 3 will conduct the impact force to the anti-collision device 4. Since both ends of the buffer plate 404 are fixedly installed at the top of the slider 403, and the slider 403 is slidably installed on the outer wall of the slide bar 402, and the buffer plate 404 is made of an elastic material, both ends of the buffer plate 404 will slide to relieve the force. Also, since the top of the damping rod 406 of the anti-collision device 4 is in contact with the buffer plate 404, at this time, the damping rod 406 will absorb a part of the impact force and thus contract. During the sliding process of the slider 403, since fixing rods 407 are symmetrically installed at the bottom of the slider 403, and springs 409 and telescopic rods 408 are connected to the ends of the fixing rods 407, the springs 409 will absorb a part of the impact force and thus be stretched. Since both ends of the slide bar 402 are fixedly connected to the inner wall of the anti-collision base 401, the remaining impact force will be conducted to the anti-collision base 401 through the slide bar 402. Since the anti-collision base 401 is designed in a concave shape, and both sides of the anti-collision base 401 are fixedly connected to the angle fixing blocks 2, at this time, the angle fixing blocks 2 will provide support for the anti-collision base 401 to absorb the remaining impact force. After the force is relieved, the springs 409 will release the absorbed impact force, pull the fixing rods 407 to reset, and at the same time, the fixing rods 407 will drive the slider 403, so that the buffer plate 404 is reset. After the buffer plate 404 is reset, the damping rod 406 releases the pressure and resets. At this time, the anti-collision device 4 is completely reset and waits for the next impact.
