Description

Laundry treating apparatus The present application claims priority to Chinese Patent Application No. CN202411035905.2 entitled "Laundry treating apparatus" filed on July 30, 2024, the entire contents of which are incorporated herein by reference. TECHNICAL FIELD

[0001] The present application relates to the field of laundry treating apparatuses, and specifically provides a laundry treating apparatus. BACKGROUND

[0002] With the continuous improvement of modern living standards and the increase in the number of family members, laundry treating apparatuses such as washing machines and washer-dryer combinations have gradually become popular as essential household appliances. Traditional laundry treating apparatuses usually have only one laundry treating drum, which cannot meet the needs of different laundry classification and care. In particular, when there are many family members, a variety of clothes, and frequent laundry care, the limitations of single-drum laundry treating apparatuses become particularly prominent.

[0003] To address this need, laundry treating apparatuses equipped with multiple laundry treating drums have gradually appeared on the market. Multi-drum laundry treating apparatuses can simultaneously process different types of laundry through zoned washing and care, thereby improving washing and care efficiency and saving time and energy. In general, more than two laundry treating drums require multiple sets of damping systems to ensure the stability of each drum during operation. However, the application of multiple damping systems also increases the structural complexity and manufacturing cost of the laundry treating apparatus.

[0004] Therefore, how to simplify the structural design while ensuring the stable operation of each drum of the laundry treating apparatus has become an important issue in the technical development of multi-drum laundry treating apparatuses. SUMMARY

[0005] The present application aims to solve the above technical problems, i.e., to solve the problem that existing multi-drum laundry treating apparatuses cannot simplify the structure while ensuring the stable operation of each drum.

[0006] The present application provides a laundry treating apparatus, characterized in that it comprises: a first drum and a second drum arranged in the height direction inside a machine shell of the laundry treating apparatus, the first drum is arranged on one side of a base of the laundry treating apparatus, the second drum is located above the first drum, the capacity of the second drum is not greater than the capacity of the first drum, and the first drum and the second drum are connected to form an integrated structure; a damping system for connecting the integrated structure to the machine shell and providing damping for the integrated structure; and an additional drum arranged in the machine shell, the capacity of the additional drum is less than the capacity of the second drum, and the additional drum is connected to the integrated structure.

[0007] The applicant has found that if the first cylinder and the second cylinder are independently connected to the cabinet, the first cylinder and the second cylinder will generate separate stress points and vibration sources, resulting in unstable overall gravity center. The first cylinder and the second cylinder are arranged along the height direction and connected to form an integrated structure, and the weight and stress of the two cylinders are more concentrated on the entire integrated structure. On this basis, the first cylinder with a larger capacity is arranged on one side of the base, and the second cylinder with a capacity not greater than that of the first cylinder is arranged above the first cylinder, so that the gravity center is stably located at the bottom, which is beneficial to effectively move the gravity center downward, so that the laundry treatment equipment is not easy to overturn and shake during operation. On this basis, the additional cylinder with a capacity smaller than that of the second cylinder is connected to the integrated structure, which has limited effect on the gravity center and does not significantly change the position of the gravity center of the equipment, so that the introduction of the additional cylinder does not require an independent damping system, and a set of damping system can be shared with the integrated structure, and the stable operation of each cylinder can still be ensured.

[0008] In the optional technical solution of the above-mentioned laundry treatment equipment, the additional cylinder is arranged above the second cylinder and connected with the second cylinder.

[0009] In the case of adopting the above technical solution, since the additional cylinder is arranged above the second cylinder, the possibility of the gravity center deviating to the side can be reduced, so that the additional cylinder can more effectively utilize the damping system of the first cylinder and the second cylinder to improve stability.

[0010] In the optional technical solution of the above-mentioned laundry treatment equipment, the additional cylinder includes a third cylinder and a fourth cylinder, both of which are located above the second cylinder and connected with the second cylinder; and a plane containing the axis of the first cylinder in the height direction is taken as a reference plane, and the third cylinder and the fourth cylinder are arranged side by side on opposite sides of the reference plane.

[0011] In the case of adopting the above technical solution, the gravity center is more centered, and when the third cylinder and the fourth cylinder operate simultaneously, the symmetrical weight distribution can make the vibrations generated by the two cylinders cancel each other out, so that the equipment can still be stable during high-speed operation, reducing the vibration and noise caused by imbalance. And because the third cylinder and the fourth cylinder have relatively small capacity, the gravity center can still be concentrated on the second cylinder and the first cylinder at the bottom, so that the equipment can still be stably operated with a low gravity center position.

[0012] In the optional technical solution of the above-mentioned laundry treatment equipment, the first cylinder is provided with a counterweight structure on the side opposite to the base.

[0013] In the case of adopting the above technical solution, the gravity center position of the integrated structure can be further adjusted, so that the gravity center is further moved to the bottom, further increasing the stability and balance of the equipment, and further reducing noise.

[0014] In the alternative technical solution of the above laundry treating device, the counterweight structure is arranged at one side of the barrel mouth of the first barrel.

[0015] In the case of using the above technical solution, the observation window of the laundry treating device is usually extended into the barrel mouth of the first barrel, thereby occupying the space of the front part of the first barrel. Due to the blocking of the observation window, the laundry and most of the water in the first barrel will not be concentrated in the above-mentioned front space, so that the front part is lighter than the rear part. Meanwhile, the rear part of the barrel is usually provided with other mechanical components, such as motors, etc., so that the rear part of the first barrel is heavier. Therefore, the counterweight structure is arranged at one side of the barrel mouth of the first barrel in the present application, so that the weight distribution of the front and rear parts of the first barrel is more uniform, the center of gravity is more centralized, the first barrel and the second barrel are more stable during high-speed operation and treating a large amount of laundry, the unbalanced vibration is reduced, the additional barrel can be operated in a more stable environment, the noise of the whole machine is reduced, and the mechanical wear is reduced.

[0016] In the alternative technical solution of the above laundry treating device, the barrel mouth of the first barrel and the barrel mouth of the second barrel are oriented in the same direction, one side of the barrel mouth of the first barrel and one side of the barrel mouth of the second barrel are connected by a first connecting piece, and one side of the barrel bottom of the first barrel and one side of the barrel bottom of the second barrel are connected by a second connecting piece.

[0017] In the case of using the above technical solution, since the diameter of the barrel mouth is smaller than that of the barrel body, connecting the first connecting piece to one side of the barrel mouth of the first barrel and one side of the barrel mouth of the second barrel can make the arrangement of the first barrel and the second barrel in the height direction more compact, which is beneficial to the reduction of the center of gravity. Similarly, connecting the second connecting piece to one side of the barrel bottom of the first barrel and one side of the barrel bottom of the second barrel can also make the arrangement of the first barrel and the second barrel in the height direction more compact, which is beneficial to the reduction of the center of gravity. Therefore, the above arrangement can further reduce the center of gravity, thereby further improving the stability of the device.

[0018] In the alternative technical solution of the above laundry treating device, the weight of the first connecting piece is greater than the weight of the second connecting piece.

[0019] In the above technical solution, the observation window of the laundry treatment device usually extends into the drum opening, thereby occupying the front portion space, and due to the blocking of the observation window, the laundry and most of the water in the drum cannot be concentrated in the above-mentioned front portion space, so that the front portion is lighter than the rear portion, and the rear portion of the drum usually has other mechanical components, such as a motor, etc., so that the rear portion of the device is heavier; therefore, the present application is configured that the weight of the first connecting member is greater than the weight of the second connecting member, so that the front and rear weight distribution is more uniform, the center of gravity is more centered, the first drum and the second drum are more stable when running at high speed and treating a large amount of laundry, the unbalanced vibration is reduced, the additional drum can run in a more stable environment, the noise of the whole machine is reduced, and the mechanical wear is reduced.

[0020] In the optional technical solution of the above laundry treatment device, the additional drum includes a first sub-drum and a second sub-drum, the capacity of the first sub-drum and the second sub-drum is less than the capacity of the second drum, the first sub-drum and the second sub-drum are located between the first drum and the second drum, and a plane containing the axis of the first drum in the height direction is a reference plane, and the first sub-drum and the second sub-drum are arranged side by side on opposite sides of the reference plane.

[0021] In the above technical solution, the center of gravity can be kept balanced and the stability can be improved; and the position is close to the first drum and the second drum, so that the damping system of the integrated structure formed by the first drum and the second drum can be more effectively utilized for damping.

[0022] In the optional technical solution of the above laundry treatment device, the third drum and the fourth drum are connected as an integrated structure.

[0023] In the above technical solution, the stability and strength of the integrated structure are enhanced, the vibration and stress can be more evenly distributed, the effect of the damping system is optimized, and the internal components are further protected from damage.

[0024] In the optional technical solution of the above laundry treatment device, the first drum and the second drum are connected by a first connecting structure to form the integrated structure; the first sub-drum and the second sub-drum are connected to the first drum by a second connecting structure; and / or the first sub-drum and the second sub-drum are connected to the second drum by a third connecting structure.

[0025] The first sub-cylinder and the second sub-cylinder are both connected to the first cylinder, so that the vibration source is concentrated in the area of the first cylinder, thereby being able to more effectively utilize the damping assembly on the first cylinder for damping. The first cylinder and the second cylinder are connected to form the integrated structure through the first connecting structure, the first sub-cylinder and the second sub-cylinder are both connected to the first cylinder through the second connecting structure, and the first sub-cylinder and the second sub-cylinder are both connected to the second cylinder through the third connecting structure, so that the overall structure is more stable, the overall rigidity of the equipment is improved, the vibration energy is dispersed and absorbed through multiple connecting points, the impact on each component of the equipment caused by vibration can be effectively reduced, thereby prolonging the service life of the equipment and improving the reliability of the equipment.

[0045] The present application provides a kind of clothes processing equipment, clothes processing equipment can be washing machine, washer-dryer, washing socks machine or clothes dryer etc.. As shown in FIG. 1 to FIG. 8, clothes processing equipment includes base 20, shell 10 on base 20, first cylinder 30, second cylinder 31, additional cylinder 32 and damping system 40, first cylinder 30, second cylinder 31 and additional cylinder 32 are arranged in shell 10, first cylinder 30 and second cylinder 31 are arranged in shell 10 along the height direction, first cylinder 30 is arranged at one side of base 20, second cylinder 31 is arranged above first cylinder 30, the capacity of second cylinder 31 is not greater than the capacity of first cylinder 30, preferably the capacity of second cylinder 31 is less than the capacity of first cylinder 30, first cylinder 30 and the second cylinder 31 are connected to form an integrated structure, damping system 40 is used to connect the integrated structure in shell 10, and provide damping for the integrated structure;Wherein, the capacity of additional cylinder 32 is less than the capacity of second cylinder 31, and additional cylinder 32 is connected to the integrated structure. First cylinder 30 and second cylinder 31 can be the outer cylinder of the drum washing machine, or be drying cylinder etc., the cylinder port of first cylinder 30 and second cylinder 31 can be oriented to the same. Wherein, first cylinder 30 and second cylinder 31 are arranged along the height direction, that is, the face containing the axis of first cylinder 30 in the height direction is taken as the reference plane, that is, the cross section at the dotted line in FIG. 1, the reference plane should be able to pass through second cylinder 31;Preferably, the reference plane also contains the axis of second cylinder 31, that is, the opposite sides of first cylinder 30 and second cylinder 31 are symmetrical relative to the reference plane.

[0046] Possibly, the capacity of first cylinder 30 can be designed as 8-12 kg, suitable for washing and care of large clothes and bedding;The capacity of second cylinder 31 can be designed as 3-6 kg, suitable for washing and care of daily clothes;The capacity of additional cylinder 32 can be designed as 0.8-1.5 kg, suitable for washing and care of small clothes or special material clothes. Specifically, the capacity of first cylinder 30 is 10 kg, the capacity of second cylinder 31 is 4 kg, and the capacity of additional cylinder 32 is 1 kg. It should be noted that the above-mentioned range of values of cylinder capacity is only exemplary, and is not intended to limit the scope of protection of the present application. The present application can adjust the specific value range according to the actual application or experimental data, as long as the capacity of first cylinder 30 is greater than the capacity of second cylinder 31, and the capacity of second cylinder 31 is greater than the capacity of additional cylinder 32. These adjustments do not deviate from the principles of the present application and are within the scope of protection of the present application.

[0047] The applicant has found that if the first drum 30 and the second drum 31 are independently connected to the cabinet 10, the first drum 30 and the second drum 31 will generate separate stress points and vibration sources, resulting in unstable overall gravity center. In the present application, the first drum 30 and the second drum 31 are arranged along the height direction and connected to form an integrated structure, and the weight and stress of the two drums are more concentrated on the entire integrated structure. On this basis, the larger-capacity first drum 30 is arranged on one side of the base 20, and the smaller-capacity second drum 31 is arranged above the first drum 30, so that the gravity center is stably located at the bottom, that is, the gravity center is effectively lowered to the first drum 30, and the gravity center of the integrated structure is lower than the support point between the two, so that the laundry treatment apparatus is not prone to overturning and shaking during operation. On this basis, the additional drum 32 with a capacity smaller than that of the second drum 31 is connected to the integrated structure, which has limited effect on the gravity center and does not significantly change the gravity center position of the apparatus, so that the introduction of the additional drum 32 does not require an independent damping system 40, and a set of damping system 40 can be shared with the integrated structure, and the stable operation of each drum can still be ensured.

[0048] As a possible implementation, the damping system 40 includes a hanging spring mechanism 401 and a damping assembly 402, and the integrated structure is hung on the cabinet 10 through the hanging spring mechanism 401, and the first drum 30 is supported on the base 20 through the damping assembly 402. Thus, the vibration and noise of the apparatus during operation can be effectively reduced, and the stability of the apparatus can be improved.

[0049] As a possible implementation, the first drum 30 is provided with a counterweight structure 50 on the side opposite to the base 20. That is, the side wall of the first drum 30 is provided with the counterweight structure 50 at the bottom in the height direction. Thus, the gravity center position of the integrated structure can be further adjusted, so that the gravity center is further moved to the bottom, and the stability and balance of the apparatus are further increased, and the noise is further reduced. Further, the counterweight structure 50 is arranged on the side of the drum opening of the first drum 30, that is, at the bottom of the drum opening in the height direction. When the laundry treatment apparatus is in operation, the observation window of the laundry treatment apparatus is usually inserted into the drum opening of the first drum 30, thus occupying the front part space of the first drum 30. Due to the obstruction of the observation window, the laundry and most of the water in the first drum 30 will not be concentrated in the above-mentioned front part space, so that the front part is lighter than the rear part. Meanwhile, the rear part of the first drum 30 is usually provided with other mechanical components, such as a motor, so that the weight of the rear part of the first drum 30 is larger. Therefore, the counterweight structure 50 is arranged on the side of the drum opening of the first drum 30, so that the weight distribution of the first drum 30 is more uniform, the gravity center is more centered, the first drum 30 and the second drum 31 are more stable during high-speed operation and processing of a large amount of laundry, unbalanced vibration is reduced, the additional drum 32 can be operated in a more stable environment, and the noise and mechanical wear of the entire machine are reduced.

[0050] One side of the counterweight structure 50 can be provided with a first arc-shaped structure 501 matching the shape of the outer wall at the barrel mouth of the first barrel 30, so as to uniformly disperse the weight of the first barrel 30, further balance the weight distribution between the first barrel 30 and the second barrel 31, and improve the stability and durability of the equipment. The first arc-shaped structure 501 and the outer wall at the barrel mouth can be connected and fixed by means of bolt connection or clamping, and the present application does not make specific limitation thereto.

[0051] The specific embodiment of the additional barrel 32 connected to the integrated structure will be described below, which includes various embodiments, and several possible embodiments will be described as examples, but it should be noted that the following several embodiments are only exemplary and are not intended to limit the protection scope of the present application, and the present application can be reasonably adjusted.

[0052] The first possible embodiment:

[0053] Referring to FIGS. 1-5, the additional barrel 32 is arranged above the second barrel 31 and connected with the second barrel 31. Since the additional barrel 32 is arranged above the second barrel 31, the possibility of the gravity center deviating to the side can be reduced, so that the additional barrel 32 can more effectively utilize the damping system 40 of the first barrel 30 and the second barrel 31 to improve the stability.

[0054] Further, the additional barrel 32 includes a third barrel 321 and a fourth barrel 322, both of which have a capacity smaller than that of the second barrel 31, are arranged above the second barrel 31, are connected with the second barrel 31, and are arranged side by side on opposite sides of the above-mentioned reference plane. The third barrel 321 and the fourth barrel 322 are preferably barrels with their axial directions parallel to the horizontal direction, so that the axial lines of the first barrel 30, the second barrel 31, the third barrel 321 and the fourth barrel 322 are parallel, and the barrel mouths are directed forward rather than upward. The capacities of the third barrel 321 and the fourth barrel 322 can be the same or different; preferably, the capacity of the third barrel 321 is the same as that of the fourth barrel 322, wherein the capacities of the third barrel 321 and the fourth barrel 322 are both smaller than that of the second barrel 31, and the capacities can be designed to be 0.8-1.5 kg, preferably 1 kg.

[0055] Since the third barrel 321 and the fourth barrel 322 are arranged side by side above the second barrel 31 and on opposite sides of the reference plane, the center of gravity is more centered. When the third barrel 321 and the fourth barrel 322 are running at the same time, the symmetrical weight distribution can make the vibrations generated by the two barrels cancel each other out, so that the equipment can still be stable in high-speed operation, reducing the vibration and noise caused by imbalance. And because the third barrel 321 and the fourth barrel 322 have relatively small capacity, the center of gravity can still be concentrated on the second barrel 31 and the first barrel 30 at the bottom, which can still maintain a low center of gravity of the equipment, so that the equipment can run stably. Possibly, the third barrel 321 and the fourth barrel 322 are symmetrically distributed relative to the reference plane. Thus, the center of gravity is further optimized and the stability of the equipment is improved.

[0056] In this application, the connection between the third barrel 321 and the second barrel 31, and the connection between the fourth barrel 322 and the second barrel 31 are not limited, and can be integrally connected or detachably connected. When it is detachably connected, the third barrel 321 and the second barrel 31 can be connected by the first connecting body 90 through bolt connection, clamping or welding, etc. Preferably, the side of the first connecting body 90 connected with the third barrel 321 is arc-shaped matched with the outer wall shape of the third barrel 321, and the side connected with the second barrel 31 is arc-shaped matched with the outer wall shape of the second barrel 31; the fourth barrel 322 and the second barrel 31 can be connected by the second connecting body 91 through bolt connection, clamping or welding, etc. Preferably, the side of the second connecting body 91 connected with the fourth barrel 322 is arc-shaped matched with the outer wall shape of the fourth barrel 322, and the side connected with the second barrel 31 is arc-shaped matched with the outer wall shape of the second barrel 31.

[0057] Possibly, referring to FIG. 3, the third barrel 321 and the fourth barrel 322 are connected as a whole, and the third barrel 321 and the fourth barrel 322 can be integrally connected or detachably connected. The third barrel 321 and the fourth barrel 322 can be connected by the third connecting body 92 through bolt connection, clamping, welding or integrally formed, etc. Preferably, the side of the third connecting body 92 connected with the third barrel 321 is arc-shaped matched with the outer wall shape of the third barrel 321, and the side connected with the fourth barrel 322 is arc-shaped matched with the outer wall shape of the fourth barrel 322. Since the third barrel 321 and the fourth barrel 322 are connected together, the stability and strength of the integrated structure can be enhanced, the vibration and stress can be more evenly distributed, the effect of the damping system 40 can be optimized, and the internal components can be further protected from damage.

[0058] Possibly, the barrel mouth side of the first cylinder 30 is connected with the barrel mouth side of the second cylinder 31 through the first connecting piece 60, and the barrel bottom side of the first cylinder 30 is connected with the barrel bottom side of the second cylinder 31 through the second connecting piece 70, so that the first cylinder 30 and the second cylinder 31 are connected to form an integrated structure. The present application does not limit the connection mode of the first connecting piece 60 and the first cylinder 30 and the second cylinder 31, and the connection mode of the second connecting piece 70 and the first cylinder 30 and the second cylinder 31, which can be detachable connection or one-piece forming.

[0059] Since the outer wall of the barrel mouth is smaller than the diameter of the barrel body, the first connecting piece 60 can be connected to the outer wall of the barrel mouth of the first cylinder 30 and the outer wall of the barrel mouth of the second cylinder 31, so that the height direction arrangement between the first cylinder 30 and the second cylinder 31 is more compact, which is beneficial to the reduction of the center of gravity. One side of the first connecting piece 60 can be provided as an arc-shaped connecting arm 601 matched with the shape of the outer wall of the second cylinder 31, so as to provide stable support for the second cylinder 31. The specific connection mode of the arc-shaped connecting arm 601 and the second cylinder 31 can be bolt connection or clamping, etc., which is not limited in the present application. The other side of the first connecting piece 60 can be provided with a first connecting arm 602 and a second connecting arm 603, and the first connecting piece 60 is connected with the outer wall of the first cylinder 30 through the first connecting arm 602 and the second connecting arm 603. The specific connection mode can be bolt connection or clamping, etc., which is not limited in the present application. The second connecting piece 70 can be connected to the barrel bottom of the first cylinder 30 and the barrel bottom of the second cylinder 31, so that the height direction arrangement between the first cylinder 30 and the second cylinder 31 is more compact, which is beneficial to the reduction of the center of gravity. The connection mode between the second connecting piece 70 and the first cylinder 30 and the second cylinder 31 can be bolt connection or clamping, etc., which is not limited in the present application.

[0060] Possibly, the weight of the first connecting piece 60 is greater than the weight of the second connecting piece 70. In the laundry treating apparatus, the observation window of the laundry treating apparatus usually extends into the barrel mouth, thus occupying the front part space. Due to the blocking of the observation window, the laundry and most of the water in the barrel will not concentrate in the above-mentioned front space, so that the front part is lighter than the rear part. Meanwhile, the rear part of the barrel usually has other mechanical components, such as motors, etc., so that the rear part of the apparatus has a larger weight. Therefore, the present application sets that the weight of the first connecting piece 60 is greater than the weight of the second connecting piece 70, so that the front and rear weight distribution is more uniform, the center of gravity is more centered, and the first cylinder 30 and the second cylinder 31 are more stable during high-speed operation and processing of a large amount of laundry, reducing unbalanced vibration, ensuring that the additional cylinder 32 can operate in a more stable environment, reducing the noise and mechanical wear of the whole machine.

[0061] Possibly, the first connecting piece 60 is made of cast iron, the second connecting piece 70 is made of plastic, and the counterweight structure 50 is made of concrete, so that the weight of the first connecting piece 60 is greater than that of the second connecting piece 70. And because the cast iron structure has high matching precision and high strength, it can realize accurate connection with the first cylinder 30 and the second cylinder 31 and ensure the connection strength between them. And the counterweight structure 50 is designed as a concrete structure, which can simplify the structure and reduce the cost under the premise of ensuring the counterweight. It should be noted that the above setting mode is only one possible embodiment, and the setting mode is not fixed. As long as the weight of the first connecting piece 60 is greater than that of the second connecting piece 70, and the counterweight structure 50 can effectively increase the weight to ensure the center of gravity, the adjustment of the setting mode does not deviate from the principle of the application, and is within the protection scope of the application.

[0062] The second possible implementation manner:

[0063] Referring to FIGS. 5-8, the additional cylinder 32 includes a first sub-cylinder 323 and a second sub-cylinder 324, the capacities of the first sub-cylinder 323 and the second sub-cylinder 324 are both less than that of the second cylinder 31, the first sub-cylinder 323 and the second sub-cylinder 324 are located between the first cylinder 30 and the second cylinder 31 and are connected with the above-mentioned integrated structure, the first sub-cylinder 323 and the second sub-cylinder 324 are arranged side by side on opposite sides of the above-mentioned reference plane, preferably symmetrically distributed with respect to the reference plane. Among them, the capacity of the first sub-cylinder 323 and the capacity of the second sub-cylinder 324 can be the same or different; preferably, the capacity of the first sub-cylinder 323 and the capacity of the second sub-cylinder 324 are the same, wherein the capacity of the first sub-cylinder 323 and the capacity of the second sub-cylinder 324 are both less than that of the second cylinder 31, and the capacity can be designed as 0.8-1.5 kg, preferably both 1 kg.

[0064] The above setting mode can keep the center of gravity balanced and improve the stability; and the position is relatively close to the first cylinder 30 and the second cylinder 31, which can more effectively utilize the damping system 40 on the integrated structure formed by the first cylinder 30 and the second cylinder 31 for damping.

[0065] As a possible implementation, in the height direction, the bottom of the first sub-cylinder 323 and the second sub-cylinder 324 is lower than the top of the first cylinder 30, and the top of the first sub-cylinder 323 and the second sub-cylinder 324 is higher than the bottom of the second cylinder 31. It can be understood that the top and bottom of the embodiment are relative to the height direction. In other words, the orthographic projection of the first sub-cylinder 323 on the reference plane and the orthographic projection of the second sub-cylinder 324 on the reference plane both have overlapping parts with the orthographic projection of the first cylinder 30 on the reference plane, and also have overlapping parts with the orthographic projection of the second cylinder 31 on the reference plane. The above arrangement makes the distance between the first cylinder 30 and the second cylinder 31 in the height direction smaller, which can more effectively reduce the center of gravity, improve the stability of the equipment, and reduce the risk of overturning.

[0066] Further, the orthographic projection of the first sub-cylinder 323 on the cross section and the orthographic projection of the second sub-cylinder 324 on the cross section both have overlapping parts with the orthographic projection of the first cylinder 30 on the cross section, and also have overlapping parts with the orthographic projection of the second cylinder 31 on the cross section. The cross section refers to a plane perpendicular to the reference plane. The above arrangement makes the distance between the first sub-cylinder 323 and the second sub-cylinder 324 in the lateral direction smaller and the arrangement in the lateral direction more compact, so that the center of gravity is more centered and the stability of the equipment is improved.

[0067] In addition, the compact and balanced arrangement in the above lateral and height directions can make the various cylinders more efficiently form a whole, so that the shock absorption system 40 can more fully play its role. When vibration occurs, the close connection and overlapping structure between the various cylinders can more effectively disperse and absorb vibration energy, reducing the impact of vibration on various parts of the equipment. At the same time, the compactness of the overall structure and the reduction of the center of gravity make the shock absorption system 40 more efficient when working, reducing the concentrated influence of the vibration transmission path and the vibration source. Thus, the efficiency of the shock absorption system 40 is maximized, not only protecting the running stability of the equipment, but also prolonging the service life of the equipment.

[0068] On the other hand, the above compact design can also improve the space utilization efficiency and realize more washing and caring functional areas in limited space.

[0069] The possible connection methods of the first sub-cylinder 323 and the second sub-cylinder 324 to the integrated structure are introduced below.

[0070] The first possible connection method:

The first connecting structure 80 can be disposed axially along the second cylinder 31 and located at the middle of the second cylinder 31 to avoid interference with the first sub-cylinder 323 and the second sub-cylinder 324. Of course, this is not a limitation, the first connecting structure 80 can also be disposed at the cylinder opening and the cylinder bottom, as long as it can connect the first cylinder 30 and the second cylinder 31 together, and these adjustments do not deviate from the principles of the present application and are within the scope of protection of the present application. The connection between the first connecting structure 80 and the first cylinder 30 and the second cylinder 31, the connection between the second connecting structure 81 and the first sub-cylinder 323 and the first cylinder 30, and the connection between the second connecting structure 81 and the second sub-cylinder 324 and the first cylinder 30 can be integrally connected, bolted, clamped, or welded, and the present application does not limit the specific connection method.

[0073] The second possible connection method is as follows:

[0074] Referring to Fig. 5, the first cylinder 30 and the second cylinder 31 are connected by the first connecting structure 80 to form the above-mentioned integrated structure, the first sub-cylinder 323 and the second sub-cylinder 324 are connected to the second cylinder 31 by the third connecting structure 82, and the two sides of the third connecting structure 82 can be symmetrical relative to the reference plane.

The connection between the first connecting structure 80 and the first cylinder 30 and the second cylinder 31 is the same as or similar to the first possible connection mode, and will not be described again.

[0077] This arrangement makes the overall structure more stable, improves the overall rigidity of the device, disperses and absorbs vibration energy through multiple connection points, can effectively reduce the impact of vibration on the components of the device, thereby prolonging the service life of the device and improving the reliability of the device.

[0078] The fourth possible connection mode is:

[0079] Referring to FIG. 8, the first sub-cylinder 323 and the second sub-cylinder 324 are both connected to the first cylinder 30 by the second connecting structure 81, and the first sub-cylinder 323 and the second sub-cylinder 324 are both connected to the second cylinder 31 by the third connecting structure 82, so that the first cylinder 30, the second cylinder 31, the first sub-cylinder 323 and the second sub-cylinder 324 are connected by the second connecting structure 81 and the third connecting structure 82 to form the integrated structure described above; preferably, the two second connecting structures 81 are symmetrical relative to the reference plane, and the two third connecting structures 82 are also symmetrical relative to the reference plane.

The above arrangement can save the setting of the first connecting structure 80, thereby simplifying the structure and reducing the cost.

[0080] It should be noted that the above-mentioned several possible connection modes are only relatively preferred embodiments, and are not intended to limit the protection scope of the present application, as long as the first sub-cylinder 323 and the second sub-cylinder 324 are connected in an integrated structure, the specific setting mode can be adjusted. For example, the first sub-cylinder 323 is connected to the first cylinder 30, the second sub-cylinder 324 is connected to the second cylinder 31, and the like, which do not deviate from the principles of the present application and are within the protection scope of the present application.

[0084] It should be noted that the front and rear of the base 20 are relative to the front and rear of the clothes processing equipment, the side close to the door body of the clothes processing equipment is the front, and the side close to the back is the rear. The cabinet 10 can further include a first side plate, a second side plate, a front plate and a back plate, the first side plate covers the first vertical beam 11 and the second vertical beam 12 on one side, the second side plate covers the first vertical beam 11 and the second vertical beam 12 on the other side, the back plate covers the two second vertical beams 12 on the rear side, and the front plate covers the two first vertical beams 11 on the front side, and necessary structures such as a dispensing opening are left. In addition, the connection mode of the first vertical beam 11 and the second vertical beam 12 with the base 20, the connection mode of the first horizontal beam 13 with the first vertical beam 11 and the second vertical beam 12, and the connection mode of the second horizontal beam 14 with the first vertical beam 11 and the second vertical beam 12 are not specifically limited by the present application, and can be integrally formed, welded, bolted, clamped, etc.

[0085] Since the first vertical beam 11 and the second vertical beam 12 are arranged on the base 20 and connected by the first horizontal beam 13 and the second horizontal beam 14, a firm structure can be formed, and the overall strength and rigidity of the cabinet 10 are enhanced.

For example, one set of spring hanging assembly can be omitted, or one set of spring hanging assembly can be added, four dampers supported on the base 20 and connected with the first cylinder 30, and the like.
