DETAILED DESCRIPTION

[0035] The present invention will be further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0036] The present invention provides a frame body structure of a double drum washing machine, such as Figure 1-6 As shown, it includes a frame body 10, which is composed of a number of vertical beams and horizontal beams. The horizontal beams include a middle horizontal beam 115, which divides the frame body into an upper tube frame body and a lower tube frame body; wherein,

[0037] The upper cylinder frame is connected to the upper cylinder via an upper cylinder connecting piece, and the lower cylinder frame is connected to the lower cylinder via a lower cylinder connecting piece;

[0038] The vertical beams include a first vertical beam 113 and a second vertical beam 114 , wherein the first vertical beam 113 is located between adjacent second vertical beams 114 ;

[0039] The first vertical beam 113 is mounted on the upper drum frame, and the upper drum 310 is connected to the first vertical beam 113 via the upper drum connector, so that the vibration force generated by the upper drum is transmitted to the first vertical beam 113. In one embodiment, generally, the upper drum 310 and the lower drum 320 are connected to the crossbeam or the vertex of the frame body 10 via a suspension spring or a suspension rod, so that the upper drum 310 and the lower drum 320 are suspended in the washing machine frame body. However, the upper drum 310 is generally small, so the suspension spring 310 or suspension rod is relatively long, that is, the outer wall of the upper drum 310 is far away from the crossbeam or the vertex of the washing machine. The long suspension spring or suspension rod makes the upper drum 310 less stable during operation.

[0040] In this embodiment, if Figure 2 As shown, the front of the washing machine is a clothing loading port, and a first vertical beam 113 is installed on the frame body 10 on the side of the washing machine. The upper drum is connected to the first vertical beam 113 through an upper drum connector to reduce the connection distance between the outer wall of the upper drum 310 and the frame body 10, that is, to reduce the length of the upper drum connector; the shorter upper drum connector improves the stability of the upper drum connector when transmitting vibration and reduces the noise generated when the washing machine is running.

[0041] The first vertical beam 113 is provided with a plurality of connection holes for connecting the upper tube connector to connect the upper tube 310 to the first vertical beam 113. In one embodiment, the plurality of connection holes can accommodate upper tubes of various specifications. The plurality of connection holes can be arranged in sequence in the vertical direction, in sequence in the horizontal direction, or in both directions to meet various needs.

[0042] At least two first vertical beams 113 are mounted on the upper drum frame, one on each side of the upper drum 310. In one embodiment, the laundry inlet of the washing machine is the front of the rectangular parallelepiped, and the first vertical beams 113 are mounted on the side of the washing machine. The upper drum is suspended within the frame body 10 via an upper drum connector.

[0043] Preferably, Figure 2 As shown, two straight first vertical beams 113 are connected to the upper drum frame, and the two first vertical beams 113 are respectively located on both sides of the washing machine. An upper drum connecting member is connected to each first vertical beam 113 so that the upper drum is suspended in the frame body 10. One end of the upper drum connecting member is connected to the connecting hole of the first vertical beam 113, and the other end is connected to the outer wall of the upper drum 310. Relative to the vertex formed by the topmost crossbeam and the adjacent crossbeam, the distance between the first vertical beam 113 and the upper drum 310 is the smallest, that is, the length of the upper drum connecting member is the shortest; the upper drum connecting member with a shorter length improves the stability of the washing machine during operation. Furthermore, the upper drum frame includes two first vertical beams, and the first vertical beam 113 is located in the middle position of the adjacent second vertical beam 114. The first vertical beam 113 is located in the middle position of the adjacent second vertical beam 114 to further improve the stability of the washing machine during operation.

[0044] In an alternative embodiment, the upper drum frame includes four linear first vertical beams 113, located on either side of the upper drum 310. Each of the four first vertical beams 113 is connected to four upper drum connectors. The four first vertical beams 113 are evenly mounted on the side of the washing machine, i.e., two first vertical beams 113 are mounted on the side frame of the washing machine, and four upper drum connectors are mounted on each of the four first vertical beams 113. The upper drum is suspended within the frame via the four upper drum connectors, reducing pressure on each upper drum connector, thereby extending the lifespan of the washing machine and increasing stability during operation.

[0045] In an alternative embodiment, a forked first vertical beam 113 is mounted on the upper cylinder frame. The first vertical beam includes at least two connecting ends for connecting to the upper cylinder connector. For example, the forked first vertical beam is a Y-shaped structure, with the two connecting ends respectively provided on the forks to match the upper cylinder connector.

[0046] It should be noted that the upper drum frame is provided with a plurality of first vertical beams 113 according to actual needs. The position and shape of the first vertical beams 113 can be set according to actual needs. For example, the upper drum frame is installed with three linear first vertical beams 113, one of which is installed on one side frame body 10 of the washing machine, and the other two are installed on the other side frame body 10 of the washing machine. The upper drum 310 is connected to three upper drum connectors that match the three first vertical beams.

[0047] The present invention also provides a twin-drum washing machine, comprising a washing machine body 100, wherein the washing machine body 100 comprises a frame structure of a twin-drum washing machine; and further comprising: an upper drum 310, a lower drum 320, an upper drum connector, and a lower drum connector. In one embodiment, people's living standards are now getting higher and higher, and while pursuing the quality of washing machines, they pay more attention to hygiene, so twin-drum washing machines are becoming more and more popular in people's lives. Generally, a twin-drum washing machine comprises a lower drum 320 and an upper drum 310, wherein the upper drum 310 is located directly above the lower drum 320, and the mass of the clothes contained in the upper drum 310 is less than the mass of the clothes contained in the lower drum 320; in addition, when the upper drum 310 of the twin-drum washing machine is in operation, the lower drum 320 lowers the center of the washing machine like a pound; when the lower drum of the washing machine is in operation, the upper drum acts as a counterweight to press down the lower drum. The lower drum is generally supported and damped by a vibration damper and a suspension spring. This means that the lower drum is placed inside the washing machine frame by the lower support of the vibration damper and the upper support of the suspension spring. Furthermore, when vibration is generated by the rotation of the drum inside the washing machine, the vibration damper and the suspension spring reduce the vibration generated on the lower drum, thereby reducing the vibration transmitted to the frame.

[0048] In one embodiment, the upper tube connection member includes a plurality of first suspension springs 210, one end of each of the first suspension springs 210 is connected to the upper tube 310, and the other end is connected to the first vertical beam 113. That is, the upper tube 310 is connected to the first vertical beam 113 via the first suspension springs 210.

[0049] Alternatively, the upper cylinder 310 is connected to the first vertical beam 113 via a suspension rod.

[0050] Specifically, the crossbeam includes a bottom crossbeam and a top crossbeam, and the top crossbeam includes a first top crossbeam 111 and a second top crossbeam 112. The first top crossbeam 111 and the second top crossbeam 112 are respectively located on both sides of the washing machine. The top crossbeam is connected to the upper drum 310 via an upper drum connector, and the bottom crossbeam is connected to the lower drum 320 via a lower drum connector. Three suspension rods are connected to the upper drum 310, one of which is connected to a first vertical beam 113 on one side of the upper drum, and the other two of the three suspension rods are connected to first vertical beams 113 on the other side of the upper drum 310. The top crossbeam is parallel to the axial direction of the upper drum 310, so that the upper drum 310 is suspended in the frame body 10 under the action of the three suspension rods. In this embodiment, the lines connecting the contact points of the three suspension rods with the top crossbeam form a triangle. The three suspension rods in the triangular structure form a stable structure, so that the upper drum is stably suspended in the washing machine frame body.

[0051] Preferably, the connections between the three suspension rods and the first vertical beam 113 form an isosceles triangle. It should be understood that the connections between the suspension rods and the first vertical beam 113 form an isosceles triangle on the same plane, that is, the connection of the suspension rods on one side of the washing machine is located at the midpoint of the line connecting the two suspension rods on the other side; the suspension rods forming an isosceles triangle structure make the upper drum more stably placed on the frame body 10 of the washing machine.

[0052] It should be noted that the number of suspension rods can be set according to actual conditions. After determining the number and positions of the suspension rods, matching first vertical beams 113 are installed on the frame body to minimize the distance between the upper tube 310 and the frame body 10.

[0053] The hanger 20 generally includes a rod body, a hanger seat, a ball seat, and a spring seat; the hanger seat is arranged at the top of the rod body, and the spring seat and the ball seat are sequentially passed through the rod body from the bottom end of the hanger, and a friction plate is provided in the ball seat, which is used to increase damping; a spherical groove is provided on the washing machine frame, and the convex spherical surface of the hanger seat cooperates with the concave spherical surface on the frame so that the upper drum is suspended on the frame of the washing machine; preferably, the hanger also includes a spring, and the spring seat, spring and ball seat are sequentially passed through the rod body from the bottom end of the hanger, and the spring plays a role in buffering and shock absorption.

[0054] In one embodiment, Figure 5As shown, the lower drum connecting member includes a plurality of vibration dampers 40, one end of each vibration damper 40 being connected to the lower drum 320 and the other end being connected to the lower drum frame. Preferably, at least three vibration dampers 40 are connected to the lower drum frame, one of the three vibration dampers 40 being located on the crossbeam on one side of the lower drum 320, and two of the three vibration dampers 40 being located on the crossbeam on the other side of the lower drum 320. The bottom crossbeam is parallel to the top crossbeam, with one end of each vibration damper connected to the lower drum and the other end connected to the bottom crossbeam. The vibration dampers 40 are used to attenuate the vibration generated in the lower drum 320 and transmit it to the frame body 10, thereby reducing the vibration amplitude of the entire washing machine. The three vibration dampers 40 make the lower drum more stable and effective in supporting and damping the vibration of the lower drum. Preferably, the lines connecting the connection points of the three vibration dampers 40 and the bottom crossbeam form an isosceles triangle. The isosceles triangle structure is similar to the isosceles triangle formed by the connecting line of the connection between the suspension rod and the top crossbeam mentioned above. The triangular structure increases stability so that the lower drum is more stably placed in the washing machine frame body.

[0055] It should be noted that the number of shock absorbers connected to the lower drum 320 can be set according to the specific situation. For example, four shock absorbers are connected to the bottom of the lower drum, and the four shock absorbers 40 are respectively placed on both sides of the lower drum to make the lower drum in a more stable structure. In addition, a larger number of shock absorbers can weaken more of the vibration force generated by the lower drum before transmitting it to the washing machine frame body, but a larger number not only increases the production cost of the washing machine but also increases the installation and maintenance process of the washing machine. In the present invention, the lower drum is preferably connected to three shock absorbers, which not only ensures the stability of the lower drum, but also effectively reduces the vibration force generated by the lower drum before transmitting it to the washing machine frame body. It should also be noted that the shock absorbers are conventional shock absorbers that can be purchased on the market.

[0056] like Figure 6As shown, a vibration-damping suspension spring 50 is installed between the upper drum 310 and the lower drum 320, with one end of the vibration-damping suspension spring 50 connected to the lower end of the upper drum 310 and the other end connected to the upper end of the lower drum 320. When the upper drum 310 and / or the lower drum 320 are in operation, the vibration force generated by the upper drum 310 and / or the lower drum 320 is weakened by the vibration-damping suspension spring 50 and then transmitted to the frame body 10. In this embodiment, the upper drum 310 and the lower drum 320 are connected by the vibration-damping suspension spring 50, and the two ends of the vibration-damping suspension spring 50 are respectively connected to the outer walls of the upper drum 310 and the lower drum 320 of the washing machine. When the upper drum 310 and the lower drum 320 are in operation simultaneously, the vibration force generated by the upper drum 310 and the lower drum 320 is weakened by the vibration-damping suspension spring 50 through the suspension rod and the vibration absorber, and is also weakened by the vibration-damping suspension spring, thereby improving the overall vibration reduction effect of the washing machine. When the upper drum 310 or the lower drum 320 is operating independently, that is, the upper drum 310 is operating while the lower drum 320 is not, or the lower drum is operating while the upper drum is not; for example, the vibration force generated by the operation of the upper drum 310 is damped by the vibration-damping spring 50 and then transmitted to the lower drum. The vibration damper connected to the lower drum 320 also acts to dampen the vibration of the upper drum. When the upper drum is stopped, the lower drum operates independently. It should be understood that the vibration-damping spring connected between the upper and lower drums makes the upper and lower drums also act as vibration dampers, enhancing the vibration damping effect of the entire washing machine.

[0057] In one embodiment, at least two vibration-damping suspension springs 50 are connected between the upper tube 310 and the lower tube 320. The two vibration-damping suspension springs 50 are symmetrically arranged about the axis of the upper tube 310. The symmetrical arrangement of the two vibration-damping suspension springs 50 ensures uniform force distribution between the upper tube 310 and the lower tube 320 during vibration transmission. Preferably, the angle formed by the extended lines of the two vibration-damping suspension springs 50 is greater than or equal to 30 degrees and less than or equal to 120 degrees. When the distance between the upper tube 310 and the lower tube 320 is constant, if the angle formed by the extended lines of the two vibration-damping suspension springs 50 is large, the two vibration-damping suspension springs 50 are connected to the edges of the lower tube 320. When the vibration-damping suspension springs 320 are located at the edges of the lower tube, the vibration force transmitted to the upper or lower tube after the vibration-damping suspension springs 50 weaken the vibration force is more dispersed. In other words, the vibration force transmitted to the upper or lower tube 310 or 320 is dispersed at the edges of the upper or lower tube, thereby enhancing the vibration-damping effect. When the angle formed by the extension lines of the two vibration-damping suspension springs 50 is small, the two vibration-damping suspension springs 50 are connected to the lower drum 320 closer to the middle position; when the vibration-damping suspension springs 50 are connected to the middle position of the lower drum 320, the vibration force transmitted to the lower drum is more concentrated. Although the concentration cannot better disperse the vibration force, when the vibration-damping suspension springs are concentrated in the middle position of the lower drum or the upper drum, the vibration-damping suspension springs play a certain supporting role on the upper drum or the lower drum, so as to reduce the pressure on the connecting parts of the upper drum or the lower drum, namely the suspension rod and the vibration absorber, so as to reduce the pressure during the operation of the entire washing machine and extend the service life of the washing machine.

[0058] In one embodiment, the washing machine body 100 further includes a second suspension spring, one end of which is fixedly mounted to the frame body 10 and the other end of which is fixedly mounted to the lower drum 320. In this embodiment, the tension spring and the vibration damper both serve as supports. One end of the tension spring is mounted to the frame body, and the other end is connected to the upper end of the lower drum. The vibration damper and the tension spring suspend the lower drum from the upper and lower portions of the frame body. Simultaneously, the tension spring also acts as a vibration damper. The vibration damper and the tension spring act simultaneously on the lower drum, weakening the vibration generated by the lower drum. This reduces the vibration transmitted to the washing machine frame body, thereby reducing the vibration amplitude of the entire washing machine.

[0059] In a specific embodiment, Figure 1 As shown, a plurality of middle cross beams 115 are vertically mounted on the vertical beams. The middle cross beams 115 are located between the upper tube and the lower tube in the vertical direction. The second suspension spring is mounted on the middle cross beams 115 to support and reduce vibration of the lower tube.

[0060] In an alternative embodiment, a third vertical beam (not shown) is mounted on the lower drum frame, and one end of the second suspension spring is fixedly mounted on the third vertical beam. Mounting the second suspension spring on the third vertical beam has the same effect as mounting the upper drum connector on the first vertical beam, namely, reducing the length of the second suspension spring to increase the stability of the lower drum during operation. Preferably, the third vertical beam is integrally formed with the first vertical beam, i.e., the first and third vertical beams are mounted on the frame body as a single beam. The integrally formed first and third vertical beams increase the overall rigidity of the washing machine.

[0061] The present invention discloses a frame body structure of a double-drum washing machine, in which a first vertical beam is installed on an upper drum frame body of the frame body structure, and the upper drum is connected to the first vertical beam through a suspension spring, so as to reduce the connection distance between the upper drum and the frame body, improve the stability of the suspension spring when transmitting vibration, and reduce the noise generated by the operation of the washing machine; in addition, a vibration-damping suspension spring is installed between the upper drum and the lower drum, one end of the vibration-damping suspension spring is connected to the lower end of the upper drum, and the other end is connected to the upper end of the lower drum; when the upper drum and the lower drum are operated simultaneously, the vibration force generated by the upper drum and the lower drum is damped by the vibration-damping suspension spring; when the upper drum or the lower drum is operated alone, the vibration force of the operating upper drum or the lower drum is transmitted to the non-operating lower drum or the upper drum after being damped by the vibration-damping suspension spring, so as to reduce the vibration force transmitted from the upper drum or the lower drum to the washing machine frame body, improve the overall stability of the washing machine, and reduce the noise generated by the operation of the washing machine.

[0062] The above are only preferred embodiments of the present invention and do not limit the present invention in any form. Any ordinary technician in this industry can smoothly implement the present invention as shown in the drawings and the above. However, any equivalent changes, modifications and evolutions made by technicians familiar with this profession without departing from the scope of the technical solution of the present invention using the technical content disclosed above are all equivalent embodiments of the present invention.
