For those skilled in the art, the specific meanings of the above terms in the present application can be understood according to specific situations.

[0025] The present application provides a drum washing machine, in combination with Figure 1 As shown, the drum washing machine provided by the present application includes a chassis housing 100, a first drum assembly 200, a second drum assembly 300, a third drum assembly 400, a fourth drum assembly 500, a connecting member 600, and a hanging spring assembly 700.

[0026] The chassis housing 100 includes a bottom plate 101.

[0027] The first drum assembly 200 and the second drum assembly 300 are disposed in the chassis housing 100, and the first drum assembly 200 is disposed below the second drum assembly 300 in the height direction. The first drum assembly 200 includes a first outer cylinder and a first inner cylinder disposed in the first outer cylinder. The first drum assembly 200 forms a first clothing access opening on the front panel of the drum washing machine, and clothing can be put into the first inner cylinder through the first clothing access opening. The second drum assembly 300 includes a second outer cylinder and a second inner cylinder disposed in the second outer cylinder. The second drum assembly 300 forms a second clothing access opening on the front panel of the drum washing machine, and clothing can be put into the second inner cylinder through the second clothing access opening.

[0028] The third drum assembly 400 and the fourth drum assembly 500 are arranged between the first drum assembly 200 and the second drum assembly 300, and are arranged along the length direction of the chassis housing 100, and the length direction is perpendicular to the height direction. The third drum assembly 400 includes a third outer cylinder and a third inner cylinder disposed within the third outer cylinder. The third drum assembly 400 forms a third clothing access opening on the front panel of the drum washing machine, and clothing can be put into the third inner cylinder through the third clothing access opening. The fourth drum assembly 500 includes a fourth outer cylinder and a fourth inner cylinder disposed within the fourth outer cylinder. The fourth drum assembly 500 forms a fourth clothing access opening on the front panel of the drum washing machine, and clothing can be put into the second inner cylinder through the fourth clothing access opening.

[0029] The connecting member 600 is fixedly provided on the chassis housing 100, and the connecting member 600 is used to connect the first drum assembly 200, the second drum assembly 300, the third drum assembly 400, and the fourth drum assembly 500.

[0030] The hanging spring assembly 700 is connected between the first drum assembly 200 and the bottom plate 101, and is used for damping the drum washing machine.

[0031] In the case of adopting the above technical solution, the drum washing machine provided by the present application realizes a compact layout of multiple drums by arranging the first drum assembly 200 and the second drum assembly 300 vertically along the height direction, and arranging the third drum assembly 400 and the fourth drum assembly 500 along the length direction between the two. Multiple independent washing units are integrated within a limited space, and independent washing of four types of clothing can be achieved, effectively solving the problem of excessive space occupied by multiple independent washing machines. The connecting member connects the four drum assemblies into an integral structure, which not only improves the positional stability between the drums, but also forms a composite damping system through the damping effect of the hanging spring assembly, enabling the washing machine to still operate smoothly under working conditions such as high-speed dehydration. In addition, the hanging spring assembly is moved down to the middle and lower part of the entire drum washing machine, which is beneficial to reducing the rocking moment of the upper drum assembly on the bottom of the chassis housing, thereby greatly reducing the amplitude of the entire chassis housing, reducing vibration and noise, and improving the user experience.

[0032] Optionally, the third drum assembly 400 and the fourth drum assembly 500 have the same size, and the first drum assembly 200 and the second drum assembly 300 have the same size. The inner diameter of the first drum assembly 200 is larger than the inner diameter of the third drum assembly 400. With such a setting, larger clothing such as outerwear and sheets can be washed using the first drum assembly 200 and the second drum assembly 300, and smaller clothing such as underwear and socks can be washed using the third drum assembly 400 and the fourth drum assembly 500. The space allocation is relatively reasonable, and at the same time, it is possible to avoid increasing the width dimension of the drum washing machine.

[0033] In some embodiments, in combination with Figure 1As shown, the hanging spring assembly 700 includes a plurality of tension springs 704. The first end of the tension spring 704 is fixedly connected to the upper side of the connecting member 600, and the second end of the tension spring 704 extends upward and is fixedly connected to the lower side of the second drum assembly 300. Among them, the plurality of tension springs 704 are symmetrically distributed on both sides of the connecting member 600 along the length direction. For example, in combination with Figure 1 As shown, there are two tension springs, and the two tension springs are symmetrically arranged on both sides of the connecting member 600.

[0034] By enabling the tension spring 704, the second drum assembly 300 can be fixed in the fourth arc-shaped groove 606 of the connecting member 600. At the same time, the plurality of tension springs 704 are symmetrically arranged on both sides of the connecting member 600 along the length direction, which can form a balanced pulling force on the second drum assembly 300 and can effectively offset the asymmetric vibration generated during the operation of the second drum assembly 300.

[0035] In some embodiments, in combination with As shown, a fourth arc-shaped groove 606 is provided on the upper side of the connecting member 600, and the lower side of the second drum assembly 300 is embedded in the fourth arc-shaped groove 606 and is flexibly connected to the fourth arc-shaped groove 606.

[0036] By providing a fourth arc-shaped groove 606 on the upper side of the connecting member 600 that matches the second drum assembly 300, the fourth arc-shaped groove 606 is flexibly connected to the second drum assembly 300, and the second drum assembly 300 is limited and connected by the tension spring 704. The second drum assembly 300 does not need to be provided with traditional hanging springs and shock absorbers. Most of the vibration energy generated when the second inner drum of the second drum assembly 300 rotates is first effectively absorbed and dissipated through the flexible connection part and the tension spring 704, and the remaining vibration energy is transmitted downward to the hanging spring assembly 700 at the lower part of the second drum assembly 300 for secondary vibration reduction. By setting the flexible connection part, not only can the overall vibration reduction effect of the drum washing machine be significantly improved, but also the load on the hanging spring assembly 700 can be greatly reduced, making its working state more stable. In addition, in this embodiment, through the optimized design of the flexible connection structure, the stress concentration problem easily generated by traditional rigid connections is avoided, and the working reliability of each component is significantly improved.

[0037] In some embodiments, a friction plate or an elastic member is provided at the connection between the second drum assembly 300 and the fourth arc-shaped groove 606. By providing a friction plate or an elastic member at the connection between the second drum assembly 300 and the fourth arc-shaped groove 606, the second drum assembly 300 can be flexibly connected to the fourth arc-shaped groove 606. The friction plate can convert the vibration energy into heat energy and dissipate it through the friction of the contact surface. The elastic element can absorb part of the impact energy through deformation.

[0038] In some embodiments, in combination with Figure 1As shown, the hanging spring assembly 700 further includes a plurality of first hanging springs 702. The first end of the first hanging spring 702 is fixedly connected to the upper side of the connecting member 600, and the second end of the first hanging spring 702 extends upward and is fixedly connected to the inner side wall of the chassis housing 100. Among them, the plurality of first hanging springs 702 are symmetrically distributed on both sides of the connecting member 600 along the length direction. For example, in combination with Figure 1 As shown, there are two first hanging springs 702, and the two first hanging springs 702 are symmetrically arranged on both sides of the connecting member 600.

[0039] By providing the inclined first hanging spring 702, vibrations in the horizontal and vertical directions can be dispersed and absorbed. The first hanging springs 702 are symmetrically distributed on both sides of the connecting member 600 along the length direction. This symmetrical structure can balance the lateral forces generated during the operation of the drum assembly, effectively suppress the swing caused by asymmetric vibrations, and improve the operating stability of the whole machine. One end of the first hanging spring 702 is fixed to the upper side of the connecting member 600, and the other end is connected to the inner side wall of the chassis housing 100, so that the vibration energy can be transmitted from the connecting member 600 to the chassis housing 100. The first hanging spring 702 and other damping structures cooperate to disperse and absorb mechanical vibrations, which can reduce the stress concentration at key connection parts, thereby reducing the risk of structural fatigue.

[0040] In some embodiments, in combination with Figure 1 As shown, the connecting member 600 includes opposite first end sides 602 and second end sides 603. Among them, the first end side 602 is provided with a second arc-shaped groove 604, at least part of the third drum assembly 400 is embedded in the second arc-shaped groove 604 and is rigidly fixedly connected to the second arc-shaped groove 604. The second end side 603 is provided with a third arc-shaped groove 605, at least part of the fourth drum assembly 500 is embedded in the third arc-shaped groove 605 and is rigidly fixedly connected to the third arc-shaped groove 605. The rigid fitting of the second arc-shaped groove 604 on the first end side 602 with the third drum assembly 400, and the rigid fitting of the third arc-shaped groove 605 on the second end side 603 with the fourth drum assembly 500 can fix the third drum assembly 400 and the fourth drum assembly 500 by using the connecting member 600. At the same time, this design effectively restricts the radial displacement of the drum assembly during high-speed rotation, suppresses the swing deviation caused by centrifugal force. In addition, due to the rigid connection, the vibration energy generated by the rotation of the third drum assembly 400 and the fourth drum assembly 500 can be guided to the hanging spring assembly 700 through the connecting member 600, so as to reduce and absorb vibrations by using the hanging spring assembly 700.

[0041] In some embodiments, in combination with Figure 1 As shown, the hanging spring assembly 700 further includes a shock absorber 701, and the shock absorber 701 is connected between the lower side of the first drum assembly 200 and the bottom plate 101.

[0042] The shock absorber 701 acts directly on the bottom of the first drum assembly 200, and absorbs the vertical vibration energy generated during the high-speed rotation of the drum through its damping characteristics, preventing the vibration from being transmitted to the chassis housing 100 through the bottom plate 101, thereby reducing the overall amplitude during the operation of the whole machine. Under the conditions of high-speed dehydration or asymmetric load, the shock absorber 701 provides dynamic support force by responding in real time to the displacement change of the drum, ensuring that the first drum assembly 200 is always in a stable operating state, and reducing mechanical wear or noise caused by vibration.

[0043] In some embodiments, as shown in Figure 1 the lower side of the connecting member 600 is provided with a first arc-shaped groove 601, the upper side of the first drum assembly 200 is embedded in the first arc-shaped groove 601, and is rigidly and fixedly connected to the first arc-shaped groove 601.

[0044] The first arc-shaped groove 601 is rigidly fitted with the first drum assembly 200, and the connecting member 600 can be used to fix the first drum assembly 200. At the same time, this design effectively restricts the displacement of the drum assembly in the radial and height directions during high-speed rotation, inhibits the swing offset caused by centrifugal force. In addition, due to the rigid connection, the vibration energy transmitted by the connecting member 600 can be transmitted downward along the first drum assembly 200 to the shock absorber 701, and the shock absorber 701 is used to reduce and absorb the vibration.

[0045] In some embodiments, as shown in Figure 1 the hanging spring assembly 700 further includes a plurality of second hanging springs 703. The first end of the second hanging spring 703 is connected to the upper side of the first drum assembly 200, and the second end of the second hanging spring 703 extends upward and is connected to the inner side wall of the chassis housing 100. Among them, the plurality of second hanging springs 703 are symmetrically distributed on both sides of the first drum assembly 200 along the length direction. For example, as shown in Figure 1 two second hanging springs 703 are provided, and the two second hanging springs 703 are symmetrically arranged on both sides of the connecting member 600.

[0046] By arranging the inclined second hanging springs 703, the vibration transmitted to the second hanging springs 703 in the horizontal and vertical directions can be dispersed and absorbed. The second hanging springs 703 are symmetrically distributed on both sides of the first drum assembly 200. This symmetrical structure can balance the lateral force generated during the operation of the drum assembly, effectively inhibit the swing caused by asymmetric vibration, and improve the operating stability of the whole machine.

[0047] Most of the vibration energy generated during the operation of the second drum assembly 300 is first effectively absorbed and dissipated through the flexible connection and the tension spring 704, and the remaining vibration energy is transmitted downward to the first suspension spring 702, the second suspension spring 703, and the shock absorber 701 for secondary vibration reduction. By setting the flexible connection, the overall vibration reduction effect of the drum washing machine can be significantly improved, and the load on the suspension spring assembly 700 can be greatly reduced, making its working state more stable. Most of the vibration energy generated during the operation of the third drum assembly 400 and the fourth drum assembly 500 is first effectively absorbed and dissipated through the tension spring 704 and the first suspension spring 702, and the remaining vibration energy is transmitted downward to the second suspension spring 703 and the shock absorber 701 for secondary vibration reduction. Most of the vibration energy generated during the operation of the first drum assembly 200 is first effectively absorbed and dissipated through the second suspension spring 703 and the shock absorber 701, and the remaining vibration energy is transmitted upward to the first suspension spring 702 and the tension spring 704 for secondary vibration reduction.

[0048] In some embodiments, in combination with Figure 1 As shown, the drum washing machine further includes a control panel 800, which is arranged between the third drum assembly 400 and the fourth drum assembly 500. The control panel 800 includes a plurality of control areas 801, and the control areas 801 correspond one-to-one to the first drum assembly 200, the second drum assembly 300, the third drum assembly 400, and the fourth drum assembly 500. Such a setting facilitates the user to quickly control each drum assembly.

[0049] In some embodiments, in combination with Figure 2 As shown, the first drum assembly 200 further includes a first door and window 202, which is rotatably arranged at the first clothing access opening; the second drum assembly 300 further includes a second door and window 302, which is rotatably arranged at the second clothing access opening; the third drum assembly 400 further includes a third door and window 401, which is rotatably arranged at the third clothing access opening; the fourth drum assembly 500 further includes a fourth door and window 501, which is rotatably arranged at the fourth clothing access opening. The third door and window 401 and the fourth door and window 501 are arranged to open in opposite directions. For example, the rotation axis of the fourth door and window 501 is arranged on the right side, and the rotation axis of the third door and window 401 is arranged on the left side.

[0050] Optionally, in combination with Figure 2 Figure 2 As shown, the drum washing machine further includes a detergent box 900, which is arranged below the first drum assembly 200.
