Description

Technical Field

[0001] This invention relates to the field of clothing processing equipment technology, and specifically provides a clothing processing device. Background Technology

[0002] To improve washing efficiency, existing technologies incorporate multiple washing drums in washing machines, catering to different sizes and types of clothing. However, this approach introduces several problems. For instance, the increased number of drums leads to a corresponding increase in the machine's height. This height raises the center of gravity, reducing stability and causing vibrations and displacement during operation. Therefore, lowering the center of gravity requires minimizing the machine's height. However, existing detergent dispensers are positioned at the front and above the drums, with the dispensing opening integrated into the dispenser. This necessitates a height that allows for convenient user dispensing, hindering a proper internal structure layout and preventing a consistently lower center of gravity for the garment processing equipment.

[0003] Accordingly, there is a need in the field for a new garment processing device to solve the problem that the center of gravity cannot be lowered due to the unreasonable internal structural layout of existing garment processing devices. Summary of the Invention

[0029] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the invention and are not intended to limit the scope of protection of the invention. Those skilled in the art can make adjustments as needed to adapt to specific applications. For example, although this application is described in conjunction with a washer-dryer combo, this is not limiting; the garment processing device of the present invention can also be other garment processing devices, such as washing machines, care washing machines, etc.

[0030] It should be noted that, in the description of this invention, the terms "upper" and "lower" refer to the upper and lower parts of the garment processing equipment in its operational state, based on the height direction. "Front" refers to the direction near the door based on the horizontal direction of the garment processing equipment in its operational state, and "rear" refers to the direction near the back of the garment processing equipment based on the horizontal direction of the garment processing equipment in its operational state.

[0031] Furthermore, it should be noted that, in the description of this invention, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0032] To address the problem that the center of gravity cannot be lowered due to the unreasonable internal structure layout of existing garment processing equipment, this invention proposes a garment processing device.

[0033] Reference Figure 1 and Figure 2 The garment processing equipment includes a housing 1, a washing drum 3, and a garment processing agent dispensing module 5. The washing drum 3 and the garment processing agent dispensing module 5 are housed within the housing 1. There are multiple washing drums 3. The garment processing agent dispensing module 5 is located at the rear or lower part of the washing drum 3. The garment processing agent dispensing module 5 is equipped with a dispensing pipe 6, which extends to the front of the washing drum 3 and connects to the dispensing port 11. The dispensing pipe 6 is designed to gradually slope downwards from front to back to accelerate the automatic flow of the garment processing agent into the garment processing agent dispensing module 5. The garment processing agent dispensing module 5 has an area for holding detergent or fabric softener, etc., and introduces the detergent or fabric softener into the washing drum 3 via water flow or directly, according to the needs of the washing program, to treat the garments accordingly.

[0034] The garment processing device of the present invention has a garment processing agent dispensing module 5 located at the rear or lower part of the washing drum 3. The garment processing agent is fed into the garment processing agent dispensing module 5 at the rear or lower part through the dispensing pipe 6 via the dispensing port 11 at the front. This design, which separates the dispensing port and the dispensing module, can make reasonable use of the internal space of the garment processing device. It can improve the flexibility of the installation position of the garment processing agent dispensing module 5, match diverse internal structural designs of the device, reduce the height of the garment processing device, thereby lowering the center of gravity and improving stability. At the same time, it can ensure that the position of the dispensing port 11 is compatible with the user's operating habits, thus ensuring a good user experience.

[0035] Although the number of washing tubs 3 in this invention is multiple, those skilled in the art can also set the number of washing tubs 3 to 1 as needed, which can also reduce the height of the clothing processing equipment. Therefore, those skilled in the art can set the number of washing tubs 3 according to actual needs and all of them fall within the protection scope of this invention.

[0036] In one possible implementation, refer to Figure 1 and Figure 2 The garment processing equipment includes a housing 1, a drying drum 2, a washing drum 3, and a garment processing agent dispensing module 5. The drying drum 2, washing drum 3, and garment processing agent dispensing module 5 are all housed within the housing 1. The garment processing agent dispensing module 5 is located at the rear or lower part of the washing drum 3. The garment processing agent dispensing module 5 is equipped with a dispensing pipe 6, which extends to the front of the washing drum 3 and connects to the dispensing port 11. (Refer to...) Figure 4 The dispensing port 11 is located on the front housing of the casing 1, allowing the user to easily place the garment treatment agent into the dispensing port 11 when facing the garment treatment device. The dispensing tube 6 is designed to gradually slope downwards from front to back. Optionally, there can be multiple dispensing tubes 6, each corresponding to a different type of garment treatment agent. Of course, the specific number of dispensing tubes 6 can be determined by those skilled in the art, and this invention does not impose any limitations on this, all of which fall within the protection scope of this invention.

[0037] The device includes multiple washing drums 3, with at least two drums having different capacities. This arrangement allows users to select the appropriate washing drum 3 based on the size and quantity of their clothes on the same garment processing device. For example, small items can be washed in a smaller drum 3, while large items can be washed in a larger drum 3. After washing both large and small items, the clothes can be directly placed into the drying drum 2 for drying, eliminating cumbersome intermediate steps and greatly improving the user experience. Furthermore, since the garment processing device of this application includes both a drying drum 2 and washing drums 3 for handling clothes of different sizes, there is no need to place conventional washing machines, wall-mounted washing machines, and separate dryers in different locations in the home, thus saving floor space.

[0038] In one possible implementation, each washing drum 3 is located at the bottom of the drying drum 2. Since the washing drum 3 requires the addition of washing water during operation, it is typically quite heavy. Therefore, placing each washing drum 3 at the bottom of the drying drum 2 lowers the center of gravity of the garment processing equipment, reducing vibration or tilting caused by instability and thus improving the overall stability of the equipment. Furthermore, placing the washing drums 3 at the bottom, rather than the top, allows the bottom structure to bear more weight without excessive pressure on the upper area. This avoids structural deformation or equipment damage due to excessive stress on the upper part, further enhancing the overall stability of the equipment.

[0039] As one possible implementation method, refer to Figure 4 The dispensing port 11 is equipped with a cover 111 that can be opened and closed. Users can easily open the cover 111 to dispense detergent and then close it. The cover 111 prevents detergent from overflowing from the dispensing port 11 due to shaking during use. Furthermore, the cover 111 also prevents dust from entering the dispensing port 11.

[0040] In one possible implementation, the washing drum 3 includes a first washing drum 31, a second washing drum 32, and a third washing drum 33. The volume of the first washing drum 31 is larger than the volumes of the second washing drum 32 and the third washing drum 33. The second washing drum 32 and the third washing drum 33 are arranged side by side above the first washing drum 31. The laundry detergent dispensing module 5 is located at the rear or lower part of the second washing drum 32 and the third washing drum 33, and above the first washing drum 31. The location of the laundry detergent dispensing module 5 at the rear of the second washing drum 32 and the third washing drum 33 ensures that the laundry detergent module 5 does not occupy the internal height space of the equipment, thereby further reducing the equipment height and center of gravity. The location of the laundry detergent dispensing module 5 at the lower part of the second washing drum 32 and the third washing drum 33 allows full utilization of the space between it and the first washing drum 31, eliminating the need for additional installation space and further reducing the equipment height and center of gravity.

[0041] The second washing drum 32 and the third washing drum 33 are arranged side-by-side above the first washing drum 31 and below the drying drum 2. This arrangement makes more efficient use of the vertical space of the garment processing equipment, resulting in a compact overall structure, clear functional division, and maximum space utilization. Furthermore, the first washing drum 31, located at the bottom, is heavier and thus increases stability, reducing vibration during washing. The second and third washing drums 32 and 33, positioned side-by-side at the top, are relatively lighter and provide more washing space without increasing the overall center of gravity. The drying drum 2, located at the top, also helps maintain balance, preventing instability caused by a high center of gravity. In short, this layout enhances the overall stability of the garment processing equipment. The first washing drum 31, with its larger volume, can hold more clothes and is suitable for large-volume washing tasks; the second and third washing drums 32 and 33, being smaller, are suitable for handling smaller loads or performing specialized washing operations. The laundry detergent dispensing module 5 is located in the space behind the second washing drum 32 and the third washing drum 33 and above the first washing drum 31, thereby improving the overall utilization rate of the internal space of the machine.

[0042] In addition, the laundry detergent dispensing module 5 can also be located at the rear or lower part of the first washing drum 31. Those skilled in the art can set it according to actual needs, and all of them fall within the protection scope of the present invention.

[0043] In one possible implementation, the volume of the drying drum 2 is greater than the volumes of the second washing drum 32 and the third washing drum 33, thereby ensuring that the drying drum 2 has sufficient space to dry clothes from each of the washing drums 3. Specifically, the volume of the drying drum 2 can be greater than the sum of the volumes of the second washing drum 32 and the third washing drum 33.

[0044] As one possible implementation, the second washing drum 32 and the third washing drum 33 have equal volumes. Equal volumes in the second and third washing drums 32 and 33 can evenly distribute the load of the clothes, ensuring a balanced load during operation, thereby improving the stability of the equipment and avoiding equipment vibration, noise, or mechanical failure caused by excessive load on one side.

[0045] In one possible implementation, the second washing drum 32 and the third washing drum 33 are located on opposite sides of the line connecting the centers of the drying drum 2 and the first washing drum 31. That is, they are located on opposite sides of the line connecting the axes of the drying drum 2 and the first washing drum 31. This effectively balances the machine's center of gravity, reducing unbalanced loads and vibrations during operation.

[0046] In one possible implementation, the drying drum 2, the first washing drum 31, the second washing drum 32, and the third washing drum 33 are all located within the same housing 1. This arrangement allows all washing and drying functions to be concentrated in the same housing 1, helping to save space and making the equipment more compact. Furthermore, this arrangement requires only a single housing 1, avoiding seams and connection points between multiple housings 1, reducing hard-to-clean areas and making cleaning and maintenance more convenient. In addition, the unified housing 1 design enhances the overall structural strength of the equipment, making it more stable during operation, reducing noise and mechanical failures caused by vibration or imbalance, and extending the equipment's service life. On the other hand, when the second washing drum 32 and / or the third washing drum 33 operate simultaneously with the drying drum 2, the drying drum 2 generates a large amount of heat. The smaller volume of the second washing drum 32 and the third washing drum 33 within the same housing 1 can effectively utilize the heat dissipated by the drying drum 2 to heat the washing water in the second washing drum 32 and the third washing drum 33, thereby improving the washing efficiency of the second washing drum 32 and the third washing drum 33.

[0047] In one possible implementation, a drying system is provided between the upper parts of the second washing drum 32 and the third washing drum 33, which are arranged side by side, and the drying drum 2. The drying system is used to provide hot air to the drying drum 2. Possibly, the drying system includes a circulating air duct, an evaporator, a condenser, a compressor, and a throttling element. The evaporator and condenser are sequentially spaced within the circulating air duct along the airflow direction. The compressor, evaporator, throttling element (throttling valve or capillary tube, etc.), and condenser are connected via refrigerant pipes to form a closed loop. A fan can be installed within the circulating air duct to promote airflow circulation. Both ends of the circulating air duct can be connected to the drying drum 2, such as one end extending into the drying drum 2 from its opening, and the other end communicating with the side wall or bottom wall of the drying drum 2. Alternatively, the air inlet of the circulating air duct can communicate with the outside air, and the air outlet of the circulating air duct can communicate with the drying drum 2, etc. As long as hot air can be provided to the drying drum 2, the specific adjustments do not deviate from the principles of this application and are within the scope of protection of this application. A bracket can be installed in the casing 1. At least the evaporator and condenser of the heat pump system are mounted on the upper side of the bracket to effectively support the heat pump system. Each washing drum 3 is located at the lower part of the bracket. The drying drum 2 is fixed to the casing 1 in the existing way or in a future possible way. For example, bearings are installed at both ends of the drying drum 2. The bearings can be fixed to the casing 1 by a support structure (such as a metal frame) to ensure that the drying drum 2 can rotate smoothly. Regarding the driving method of the rotation of the drying drum 2, an electric motor can transmit power to the drying drum 2 through a belt or gear to make it rotate. Of course, the drying drum 2 can also be directly fixed to the casing 1, and its non-rotational manner does not deviate from the principle of this application and is also within the protection scope of this application.

[0048] The drying system is directly installed between the side-by-side washing drum 3 and drying drum 2, which can combine the space that originally required two separate systems (washing and drying) into a compact unit, eliminating unnecessary space and reducing the overall volume.

[0049] In one possible implementation, the second washing drum 32 and the third washing drum 33 are connected by the first connecting member 4. This application does not limit the specific manner in which the second washing drum 32 and the third washing drum 33 are connected by the first connecting member 4, as long as they can be connected together. For example, the first connecting member 4 is located between the second washing drum 32 and the third washing drum 33, and is integrally formed with both the second and third connecting drums. Alternatively, the first connecting member 4 can be bolted to both the second washing drum 32 and the third washing drum 33, etc. The first connecting member 4 can be plate-shaped or block-shaped, etc., and this application does not impose specific limitations on this.

[0050] During operation of the garment processing equipment, especially during the washing process, the washing drum 3 may experience some shaking or vibration due to the impact of water flow and the tumbling of clothes. The connection between the second washing drum 32 and the third washing drum 33 via the first connector 4 effectively limits any potential relative displacement between them, preventing collisions or friction with other components due to excessive relative displacement. Since the second and third washing drums 32 and 33 have equal volumes, their connection via the first connector 4 facilitates a more even distribution of the garment load between the two drums 3 during washing. Even in cases of uneven garment loading, the first connector 4 provides some adjustment, ensuring that the second and third washing drums 32 and 33 share the load, preventing vibration, noise, or mechanical failures caused by excessive load on one side, thus effectively improving the stability and performance of the equipment.

[0051] As one possible implementation, the connected second washing drum 32 and third washing drum 33 are independently set up from the first washing drum 31. That is, the third washing drum 33 is not connected to either the first washing drum 31 or the second washing drum 32. This arrangement allows the first washing drum 31 to more independently and precisely adjust its operating parameters, such as rotation speed, according to its own load conditions, thereby achieving more optimized load balance and reducing vibration and instability caused by uneven load.

[0052] As an alternative implementation, both the second washing drum 32 and the third washing drum 33 are connected to the first washing drum 31 via a second connector (not shown in the figure). Since the first washing drum 31 is typically heavier and located at the bottom, it is a key factor in stabilizing the equipment's center of gravity. Connecting the second washing drum 32 and the third washing drum 33 to the first washing drum 31 further optimizes the equipment's center of gravity, preventing tipping or excessive shaking during operation due to a shift in the center of gravity. The connection method between the second connector and the first washing drum 31 and the second washing drum 32, as well as the connection method between the second connector and the first washing drum 31 and the third washing drum 33, can be integrally formed or detachably connected using methods such as bolts or snap-fits. The second connector can be plate-shaped or block-shaped, etc., and this application does not impose specific limitations in this regard.

[0053] In one possible implementation, the first washing drum 31, the second washing drum 32, and the third washing drum 33 are all independently supported within the housing 1 of the garment processing equipment by shock absorbers. That is, the first washing drum 31, the second washing drum 32, and the third washing drum 33 are all independently supported within the housing 1 by shock absorbers. For example, the bottom of the first washing drum 31 can be connected to the base of the housing 1 by multiple shock absorbers, which can be installed at the four corners of the bottom of the washing drum 3, or arranged in a triangular pattern. The bottom of the second washing drum 32 on the side closest to the housing 1 can be connected to the crossbeam of the housing 1 by shock absorbers; similarly, the bottom of the third washing drum 33 on the side closest to the housing 1 can also be connected to the crossbeam of the housing 1 by shock absorbers. However, this connection is not restrictive; as long as each washing drum 3 is independently supported within the housing 1 of the garment processing equipment by shock absorbers, any adjustments to the specific arrangement do not deviate from the principles of this application and are within the scope of protection of this application.

[0054] Because each washing drum 3 is supported by an independent shock absorber, the vibrations generated by each drum can be effectively dispersed and absorbed, preventing the transmission of vibrations between them. This makes the overall equipment more stable during operation, especially when multiple drums are working simultaneously, reducing the possibility of mutual interference. In addition, the shock absorber of each washing drum 3 can be adjusted independently to optimize shock absorption according to the load changes generated during the washing process, thereby reducing the intensity of vibration and effectively reducing the vibration and noise generated by the washing drum 3 under high-speed rotation and centrifugal force.

[0055] Alternatively, each washing drum 3 may also be suspended in the housing 1 by a spring assembly to further ensure the stability of the garment processing equipment during operation.

[0056] Possibly, the first washing drum 31, the second washing drum 32, and the third washing drum 33 described above in this application are all outer drums, with a rotatable inner drum inside each washing drum 3. The specific implementation of rotatably locating the inner drum inside the outer drum is quite mature and will not be elaborated further. Alternatively, the inner drum can be omitted. In this case, the first washing drum 31, the second washing drum 32, and the third washing drum 33 can also be closed washing drums 3, etc. These adjustments do not deviate from the principles of this application and are all within the protection scope of this application.

[0057] As one possible implementation method, refer to Figure 3 The garment processing equipment is equipped with a water inlet piping system. This system extends from back to front between the second washing drum 32 and the third washing drum 33, into each of the three washing drums 3. This cleverly utilizes the space between the two washing drums inside the equipment, eliminating the need for a dedicated piping area. This effectively reduces the lateral and longitudinal space occupied by the piping, resulting in a more compact and rational internal layout. This allows for the integration of more functions or the accommodation of larger washing drums within a limited machine space.

[0058] The water inlet piping system has a dual function: it is responsible for supplying the required washing water to each washing drum 3 during the washing process, and at the same time, it is responsible for supplying the spray water required for the spray operation to the window mat or viewing window during the washing process.

[0059] The laundry detergent dispensing module 5 includes a storage chamber and a premixing chamber (not shown in the figure). A dispensing pipe 6 connects to the storage chamber, and the premixing chamber is located above it. The storage chamber and the premixing chamber are connected by an inlet pipe equipped with a liquid pump. The liquid pump draws the laundry detergent from the storage chamber into the premixing chamber. The liquid pump can precisely dispense the appropriate amount of laundry detergent according to washing requirements. In the premixing chamber, the washing water and laundry detergent are thoroughly mixed and diluted before being sent into the corresponding washing drum 3.

[0060] Specifically, the water inlet pipeline system includes a first water inlet pipe 71 and a first spray pipe 72 connected to a water source, and the first water inlet pipe 71 and the first spray pipe 72 are respectively connected to the first washing drum 31.

[0061] The water inlet pipeline system also includes a second water inlet pipe 73 and a second spray pipe 74 connected to the water source. The second water inlet pipe 73 and the second spray pipe 74 are respectively connected to the second washing drum 32.

[0062] The water inlet piping system also includes a third water inlet pipe 75 and a third spray pipe 76 connected to the water source. The third water inlet pipe 75 and the third spray pipe 76 are respectively connected to the third washing drum 33.

[0063] The first water inlet pipe 71, the second water inlet pipe 73, and the third water inlet pipe 75 are respectively connected to the premixing chamber on the laundry detergent dispensing module. In the premixing chamber, the washing water can dilute the laundry detergent and then smoothly send it into the corresponding washing drum 3.

[0064] Each washing drum has its own independent water inlet and spray pipes, allowing for precise adjustment of water volume and pressure based on the actual washing needs of the clothes in each drum (such as the amount, material, and degree of soiling). The independent and clearly defined piping layout ensures that each pipe has a clear function and simple, direct connections. When a blockage or leak occurs in the pipe corresponding to a particular washing drum, maintenance personnel can quickly locate the problem and inspect and repair only the faulty pipe, eliminating the need for a large-scale inspection of the entire water supply system. This significantly reduces repair time and maintenance costs.

[0065] As one possible implementation, the garment handling device also includes a first vent pipe, a second vent pipe, and a third vent pipe (not shown in the figure) connected to the outside air. The first vent pipe is connected to the first washing drum, the second vent pipe is connected to the second washing drum, and the third vent pipe is connected to the third washing drum. During the washing process, especially during the water filling and draining stages, the air pressure inside the washing drum 3 changes. When water is added to the washing drum 3, the existing air inside the drum is compressed, and the air pressure increases; when draining, the volume of air inside the drum increases, and the air pressure decreases. The vent pipes, connected to the outside air, can introduce or expel air in a timely manner, balancing the air pressure inside and outside the washing drum 3. For example, during water filling, outside air enters the washing drum 3 through the vent pipes, preventing excessively high air pressure inside the drum from causing pressure damage to the drum wall and ensuring a smooth water filling process; during draining, air inside the drum is discharged through the vent pipes, avoiding negative pressure due to excessively low air pressure that hinders drainage and ensuring drainage efficiency.

[0066] It should also be noted that although the present invention is described in detail using three washing drums 3 as an example, those skilled in the art can set the number of washing drums 3 according to actual needs. It can also be set to four, five or more, without departing from the principle of the present invention and all falling within the protection scope of the present invention.

[0067] The technical solution of the present invention has been described above with reference to the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the scope of protection of the present invention is obviously not limited to these specific embodiments. Without departing from the principles of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after such changes or substitutions will all fall within the scope of protection of the present invention.
