Description

Laundry treating apparatus This application claims priority to Chinese Patent Application CN202411035916.0, filed on July 30, 2024, entitled "Laundry treating apparatus", 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 improvement of people's living standards, laundry treating apparatuses such as washing machines and washer-dryer combinations, as indispensable household appliances in family life, their functions and designs are increasingly diversified and personalized. Partition washing and caring technology has been favored by more and more families because it can independently wash according to the characteristics of clothes. At present, there are mainly two design schemes on the market, namely, a horizontal double-barrel laundry treating apparatus and a vertical compound laundry treating apparatus.

[0003] The horizontal double-barrel laundry treating apparatus usually adopts a pulsator type design, and two laundry treating drums are arranged side by side on the same horizontal plane. However, due to the large floor area of the horizontal double-barrel laundry treating apparatus, most users prefer vertical laundry treating apparatuses. However, for vertical laundry treating apparatuses with more than two drums, the vibrations of different frequencies and amplitudes generated during operation will cause the whole machine to shake more severely under the cumulative effect. Therefore, the current vertical laundry treating apparatuses can usually only realize the layout of two laundry treating drums, and for multi-member families, the number of laundry treating drums is still limited. For example, multi-member families often need to simultaneously treat multiple different types of clothes, such as baby clothes, adult clothes, and clothes made of special materials, etc. The existing vertical laundry treating apparatuses cannot meet the demand for multiple partition washing and caring.

[0004] Therefore, there is a need in the art for a new laundry treating apparatus to solve the problem that the existing vertical laundry treating apparatuses cannot guarantee stability on the premise of realizing multi-drum layout. SUMMARY

[0005] The present application aims to solve the above technical problems, i.e., to solve the problem that the existing vertical laundry treating apparatuses cannot guarantee stability on the premise of realizing multi-drum layout.

[0006] The application provides a clothes treatment device, characterized by comprising: a first drum and a second drum arranged in a height direction in a machine shell of the clothes treatment device, the first drum is arranged at one side of a base of the clothes treatment device, the second drum is 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; and an additional drum arranged in the machine shell, the capacity of the additional drum is less than the capacity of the second drum.

[0007] The applicant finds that if the first drum and the second drum are independently connected to the machine shell, the first drum and the second drum will generate separate stress points and vibration sources, resulting in unstable overall gravity center. In the application, the first drum and the second drum are arranged in a height direction and connected to form an integrated structure, the weight and stress of the two drums are more concentrated on the entire integrated structure. On this basis, the first drum with a larger capacity is arranged at one side of the base, and the second drum with a capacity not greater than the first drum is arranged above the first drum, so that the gravity center is stably located at the bottom, and the clothes treatment device is not easy to overturn and shake during operation. On this structure, the additional drum with a capacity smaller than the second drum is added, which has limited effect on the gravity center. Thus, not only the gravity center position of the device is not significantly changed, but also additional functions and flexibility are provided while ensuring the stable operation of each drum, avoiding shaking of the entire device, reducing noise, improving stability, and realizing the partitioned washing and protection requirements of the clothes treatment device with more than two drums.

[0008] In the optional technical solution of the above clothes treatment device, the additional drum is above the second drum.

[0009] In the case of using the above technical solution, the possibility of gravity center deviation to the side can be reduced, thereby improving the stability of device operation.

[0010] In the optional technical solution of the above clothes treatment device, the additional drum comprises a third drum and a fourth drum, the capacity of the third drum and the fourth drum is less than the capacity of the second drum, the third drum and the fourth drum are arranged side by side above the second drum, and a plane containing the axis of the first drum in the height direction is used as a reference plane, the third drum and the fourth drum are located on opposite sides of the reference plane.

[0011] In the case of using the above technical solution, the gravity center is more centered, and when the third drum and the fourth drum operate at the same time, the vibration forces can be offset to each other, thereby reducing the influence on the overall stability of the device, reducing vibration and shaking, and improving the smoothness of operation. And because the third drum and the fourth drum have relatively small capacity, the gravity center can still be concentrated on the second drum and the first drum at the bottom, and the low gravity center position of the device can still be maintained, so that the device can operate stably.

[0012] In the alternative technical solution of the above laundry treating device, the additional drum is independently arranged with the integrated structure.

[0013] In the case of adopting the above technical solution, the mutual influence between the drums can be reduced, and the operation stability and reliability of the device can be improved. In addition, such arrangement makes it convenient to upgrade and expand when necessary, such as replacing or repairing the additional drum, thereby increasing the convenience.

[0014] In the alternative technical solution of the above laundry treating device, the drum opening of the first drum and the drum opening of the second drum are oriented in the same direction, one side of the drum opening of the first drum and one side of the drum opening of the second drum are connected by a first connecting piece, and one side of the drum bottom of the first drum and one side of the drum bottom of the second drum are connected by a second connecting piece.

[0015] In the case of adopting the above technical solution, since the diameter of the drum opening is smaller than that of the drum body, connecting the first connecting piece to one side of the drum opening of the first drum and one side of the drum opening of the second drum can make the arrangement of the first drum and the second drum in the height direction more compact, which is conducive to the reduction of the center of gravity. Similarly, connecting the second connecting piece to one side of the drum bottom of the first drum and one side of the drum bottom of the second drum can also make the arrangement of the first drum and the second drum in the height direction more compact, which is conducive 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.

[0016] 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.

[0017] In the case of adopting the above technical solution, the observation window of the laundry treating device usually extends into the drum opening, thereby occupying the space in the front part. Due to the obstruction of the observation window, the clothes and most of the water in the drum 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 drum usually has other mechanical components, such as motors, etc., so that the weight of the rear part of the device is larger. Therefore, by arranging the weight of the first connecting piece to be greater than the weight of the second connecting piece, the weight distribution of the front and rear parts is more uniform, the center of gravity is more centered, the first drum and the second drum are more stable during high-speed operation and processing of a large amount of clothes, the unbalanced vibration is reduced, the additional drum can operate in a more stable environment, and the noise of the whole machine and the mechanical wear are reduced.

[0018] In the alternative technical solution of the above laundry treating device, the first drum is provided with a counterweight structure on the side opposite to the base.

[0019] In the case of adopting the above technical solution, the center of gravity of the integrated structure can be further adjusted, so that the center of gravity is further moved to the bottom, thereby further increasing the stability and balance of the device and further reducing the noise.

[0020] In the alternative technical solution of the above laundry treating apparatus, the counterweight structure is arranged at one side of the barrel mouth of the first barrel.

[0021] In the case of using the above technical solution, the observation window of the laundry treating apparatus 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 obstruction 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 usually has 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 when running at high speed and treating a large amount of laundry, the unbalanced vibration is reduced, the additional barrel can run in a more stable environment, the noise and mechanical wear of the whole machine are reduced.

[0022] In the alternative technical solution of the above laundry treating apparatus, the laundry treating apparatus further comprises a first hanging spring assembly and a first damping assembly, the third barrel and the fourth barrel are connected to form an integrated structure; the third barrel and the fourth barrel are hung on the cabinet through the first hanging spring assembly; the third barrel and the fourth barrel are supported on the cabinet through the first damping assembly.

[0023] In the case of using the above technical solution, the integrated third barrel and fourth barrel are connected to the cabinet through the first hanging spring assembly and the first damping assembly, so that the transmission path of vibration is more direct, the relative movement between the independent barrels is reduced, the load and stress can be more effectively distributed, the vibration and impact during operation can be effectively dispersed and absorbed, the damping effect is more excellent, and the overall stability and consistency of the apparatus are improved.

[0024] In the alternative technical solution of the above laundry treating apparatus, the cabinet comprises first vertical beams and second vertical beams, the first vertical beams are arranged at opposite sides of the front part of the base, the second vertical beams are arranged at opposite sides of the rear part of the base, first horizontal beams and second horizontal beams are connected between the first vertical beam and the second vertical beam at the same side, the first horizontal beam is located above the second horizontal beam, the first hanging spring assembly is hung on the first horizontal beams at both sides, and the first damping assembly is supported on the second horizontal beams at both sides.

[0025] In the technical scheme, the first vertical beam and the second vertical beam are arranged on the base and connected by the first horizontal beam and the second horizontal beam, so that a firm structure is formed, the overall strength and rigidity of the cabinet are enhanced, and on this basis, the first horizontal beam and the second horizontal beam provide stable suspension and support basis for the first spring hanging assembly and the first damping assembly, so that the third drum and the fourth drum can be kept stable during operation and vibration and noise are reduced.

[0026] In the optional technical scheme of the laundry treating apparatus, the laundry treating apparatus further comprises a second spring hanging assembly, a third spring hanging assembly and a second damping assembly, the second drum is hung on the cabinet by the second spring hanging assembly, the first drum is hung on the cabinet by the third spring hanging assembly, and the first drum is supported on the base by the second damping assembly.

[0027] In the technical scheme, the vibration and noise of the apparatus during operation can be effectively reduced, and the stability of the apparatus is improved.

[0028] In the optional technical scheme of the laundry treating apparatus, the third horizontal beam is located between the first horizontal beam and the second horizontal beam, the fourth horizontal beam is located between the second horizontal beam and the base, the second spring hanging assembly is hung on the third horizontal beams on both sides, and the third spring hanging assembly is hung on the fourth horizontal beams on both sides.

[0029] In the technical scheme, the spring hanging assembly and the damping assembly are arranged on horizontal beams at different heights, so that the stress distribution of the whole apparatus is more uniform, the stability of the apparatus is improved, and shaking or tilting during operation is prevented. Since the first damping assembly on the third drum and the fourth drum on the uppermost layer is arranged on the second horizontal beam which is lower than the first horizontal beam and the third horizontal beam, and the second spring hanging assembly of the second drum is hung on the third horizontal beam, the layout between the second drum and the third drum and the fourth drum on the upper part is more compact, so that the center of gravity is lowered as much as possible, and the stability and safety of the whole apparatus during operation are improved.

Those skilled in the art can understand the specific meaning of the above terms in the present application according to the specific circumstances.

[0041] 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 Figure 1 to Figure 4, clothes processing equipment includes base 20 and is set on base 20 shell 10, 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 the height direction in shell 10, 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 between connection is formed integrated structure, wherein, the capacity of additional cylinder 32 is less than the capacity of second cylinder 31.Both first cylinder 30 and second cylinder 31 can be the outer cylinder of drum washing machine, or be drying cylinder etc..Among them, first cylinder 30 and second cylinder 31 are arranged in the height direction, that is, with the face containing the axis of first cylinder 30 in the height direction as reference surface, the face of dotted line in Figure 1, the reference surface should be able to pass through second cylinder 31;Preferably, the reference surface 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 surface.

[0042] 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.For example, 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, and the present application can be adjusted according to actual application or experimental data to its specific value range, 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.

[0043] The applicant found that if the first cylinder 30 and the second cylinder 31 are independently connected to the cabinet 10, the first cylinder 30 and the second cylinder 31 will generate separate stress points and vibration sources, resulting in unstable overall gravity center. The first cylinder 30 and the second cylinder 31 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 30 with a larger capacity is arranged on one side of the base 20, and the second cylinder 31 with a smaller capacity is arranged above the first cylinder 30, so that the gravity center is stably located at the bottom, that is, the gravity center is effectively lowered to the first cylinder 30. The gravity center of the integrated structure is lower than the support point between the two, so that the clothes treatment equipment is not easy to overturn and shake during operation. On this structure, an additional cylinder 32 smaller than the second cylinder 31 is added, which has limited effect on the gravity center. Therefore, not only the gravity center of the equipment will not change significantly, but also additional functions and flexibility can be provided while ensuring the stable operation of each cylinder, avoiding the shaking of the whole machine, reducing noise, improving stability, and realizing the partition washing and protection requirements of the clothes treatment equipment with more than two cylinders.

[0044] Possibly, the first cylinder 30 and the second cylinder 31 of the present application have the same direction of the cylinder port, the side of the cylinder port of the first cylinder 30 and the side of the cylinder port of the second cylinder 31 are connected by the first connecting piece 70, and the side of the cylinder bottom of the first cylinder 30 and the side of the cylinder bottom of the second cylinder 31 are connected by the second connecting piece 80, 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 70 and the first cylinder 30 and the second cylinder 31, and the connection mode of the second connecting piece 80 and the first cylinder 30 and the second cylinder 31, which can be detachable connection or integrated molding.

[0045] Since the outer wall of the barrel mouth is smaller than the diameter of the barrel body, the first connecting piece 70 can be connected to the outer wall of the barrel mouth of the first barrel 30 and the outer wall of the barrel mouth of the second barrel 31, so that the arrangement between the first barrel 30 and the second barrel 31 in the height direction is more compact, which is beneficial to the reduction of the center of gravity. One side of the first connecting piece 70 can be provided as an arc-shaped connecting arm 701 matched with the shape of the outer wall of the second barrel 31, so as to provide stable support for the second barrel 31. The specific connection mode between the arc-shaped connecting arm 701 and the second barrel 31 can be bolt connection or clamping, and the like, and the present application does not make specific limitation thereon. The other side of the first connecting piece 70 can be provided with a first connecting arm 702 and a second connecting arm 703, and the first connecting piece 70 is connected to the outer wall of the first barrel 30 through the first connecting arm 702 and the second connecting arm 703. The specific connection mode can be bolt connection or clamping, and the like, and the present application does not make specific limitation thereon. The second connecting piece 80 can be specifically connected to the barrel bottom of the first barrel 30 and the barrel bottom of the second barrel 31, so that the arrangement between the first barrel 30 and the second barrel 31 in the height direction is more compact, which is beneficial to the reduction of the center of gravity. The connection mode between the second connecting piece 80 and the first barrel 30 and the second barrel 31 can be bolt connection or clamping, and the like, and the present application does not make specific limitation thereon.

[0046] Possibly, the weight of the first connecting piece 70 is greater than the weight of the second connecting piece 80. The observation window of the clothes treatment equipment usually extends into the barrel mouth, thereby occupying the space of the front part. Due to the blockage of the observation window, the clothes and most of the water in the 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 usually has other mechanical components, such as motors, etc., so that the weight of the rear part of the equipment is larger. Therefore, the present application makes the front and rear weight distribution more uniform by setting the weight of the first connecting piece 70 to be greater than the weight of the second connecting piece 80, so that the center of gravity is more centered, and the first barrel 30 and the second barrel 31 are more stable when running at high speed and processing a large amount of clothes, thereby reducing unbalanced vibration, ensuring that the additional barrel 32 can operate in a more stable environment, reducing the noise and mechanical wear of the whole machine.

[0047] As a possible implementation manner, the first barrel 30 is provided with a counterweight structure 60 on the side opposite to the base 20. That is, the side wall of the first barrel 30 is provided with the counterweight structure 60 at the bottom in the height direction. Therefore, the center of gravity of the integrated structure can be further adjusted, so that the center of gravity is further moved to the bottom, thereby further increasing the stability and balance of the equipment and further reducing the noise.

[0048] On the basis that the counterweight structure 60 is arranged on the side of the first cylinder 30 opposite the base 20, further, the counterweight structure 60 is arranged on the side of the cylinder mouth of the first cylinder 30, that is, on the bottom of the cylinder mouth in the height direction. When the clothes processing device is running, the observation window of the clothes processing device is usually inserted into the cylinder mouth of the first cylinder 30, thereby occupying the space of the front part of the first cylinder 30. Due to the blocking of the observation window, the clothes and most of the water in the first cylinder 30 will not concentrate into the above-mentioned front space, so that the front part is lighter than the rear part, and meanwhile, the rear part of the cylinder usually has other mechanical components, such as a motor, etc., so that the rear part of the first cylinder 30 is heavier; therefore, the present application arranges the counterweight structure 60 on the side of the cylinder mouth of the first cylinder 30, so that the weight distribution of the front and rear parts of the first cylinder 30 is more uniform, the center of gravity is more centered, the first cylinder 30 and the second cylinder 31 are more stable when running at high speed and processing a large amount of clothes, unbalanced vibration is reduced, the additional cylinder 32 can run in a more stable environment, and the noise and mechanical wear of the whole machine are reduced.

[0049] One side of the counterweight structure 60 can be arranged as a first arc-shaped structure 601 matched with the shape of the outer wall at the cylinder mouth of the first cylinder 30, so as to uniformly disperse the weight of the first cylinder 30 and further balance the weight distribution between the first cylinder 30 and the second cylinder 31, thereby improving the stability and durability of the device. The first arc-shaped structure 601 and the outer wall at the cylinder mouth can be connected and fixed by bolt connection or clamping, etc., and the present application does not make specific limitation thereon.

[0050] Possibly, the first connecting piece 70 is a cast iron structure, the second connecting piece 80 is a plastic structure, and the counterweight structure 60 is a concrete structure, so that the weight of the first connecting piece 70 is greater than that of the second connecting piece 80. And due to the high matching precision and high strength of the cast iron structure, the precise connection between the first connecting piece 70 and the first cylinder 30 and the second cylinder 31 can be realized and the connection strength therebetween can be ensured. And the counterweight structure 60 designed as a concrete structure can simplify the structure and reduce the cost on the premise of ensuring the counterweight. It should be noted that the above-mentioned arrangement is only one possible embodiment, and the arrangement is not unchangeable, as long as the weight of the first connecting piece 70 is greater than that of the second connecting piece 80 and the counterweight structure 60 can effectively increase the weight to ensure that the center of gravity is centered, the adjustment of the arrangement does not deviate from the principle of the present application and is within the protection scope of the present application.

[0051] As a possible implementation, the additional cylinder 32 comprises a third cylinder 321 and a fourth cylinder 322, both having a smaller volume than the second cylinder 31, and both being arranged side by side above the second cylinder 31 and on opposite sides of the reference plane. Both the third cylinder 321 and the fourth cylinder 322 are preferably cylinders with their axes parallel to the horizontal direction, so that the axes of the first cylinder 30, the second cylinder 31, the third cylinder 321 and the fourth cylinder 322 are all parallel, with the cylinder openings facing forward rather than upward. The third cylinder 321 and the fourth cylinder 322 can have the same volume or different volumes. Preferably, the third cylinder 321 and the fourth cylinder 322 have the same volume, which is smaller than the volume of the second cylinder 31. The volume of the third cylinder 321 and the fourth cylinder 322 can be designed to be 0.8-1.5 kg, and is preferably 1 kg.

[0052] Since the third cylinder 321 and the fourth cylinder 322 are arranged side by side above the second cylinder 31 and on opposite sides of the reference plane, the center of gravity is more centered, and when the third cylinder 321 and the fourth cylinder 322 are operating simultaneously, the vibration forces can be offset, thereby reducing the impact on the overall stability of the device, reducing shaking and swaying, and improving the smoothness of operation. Since the third cylinder 321 and the fourth cylinder 322 have relatively small volumes, the center of gravity is still concentrated on the second cylinder 31 and the first cylinder 30 at the bottom, and the device can still maintain a low center of gravity, so that the device can operate stably. Possibly, the third cylinder 321 and the fourth cylinder 322 are symmetrically distributed relative to the reference plane, thereby further optimizing the center of gravity and improving the stability of the device.

[0053] As a possible implementation, the third cylinder 321 and the fourth cylinder 322 are independently arranged with the integrated structure formed by the first cylinder 30 and the second cylinder 31. That is, the third cylinder 321 is not connected to the integrated structure, and the fourth cylinder 322 is also not connected to the integrated structure. This can reduce the mutual influence between the cylinders and improve the smoothness and reliability of the device. In addition, this arrangement makes it easy to upgrade and expand when needed, such as replacing or repairing the additional cylinder 32, which increases convenience.

[0054] As a possible implementation, as shown in FIG. 5, the third cylinder 321 and the fourth cylinder 322 are connected to form an integrated structure. The third cylinder 321 and the fourth cylinder 322 can be integrally formed to form an integrated structure, or can be detachably connected to form an integrated structure through the connecting structure 90. Possibly, one side of the connecting structure 90 is provided as a second arc-shaped structure 901 matched with the shape of the outer wall of the third cylinder 321, and the other side of the connecting structure 90 is provided as a third arc-shaped structure 902 matched with the shape of the outer wall of the fourth cylinder 322. The second arc-shaped structure 901 and the outer wall of the third cylinder 321, and the third arc-shaped structure 902 and the outer wall of the fourth cylinder 322 can be connected by bolt connection, clamping, integral forming, etc., which is not specifically limited by the present application. Possibly, the clothes treatment apparatus further comprises a first hanging spring assembly 40 and a first damping assembly 50; the third cylinder 321 and the fourth cylinder 322 are hung on the cabinet 10 through the first hanging spring assembly 40; and the third cylinder 321 and the fourth cylinder 322 are supported on the cabinet 10 through the first damping assembly 50.

[0055] The third cylinder 321 and the fourth cylinder 322 which are integrally formed are connected to the cabinet 10 through the first hanging spring assembly 40 and the first damping assembly 50, so that the transmission path of vibration is more direct, the relative movement between the independent cylinders is reduced, the load and stress can be more effectively distributed, the vibration and impact during operation can be effectively dispersed and absorbed, the damping effect is more excellent, and the overall stability and consistency of the apparatus are improved.
