Description

Technical Field

[0001] This disclosure relates to the field of household appliance technology, and more particularly to a garment processing device. Background Technology

[0002] In related technologies, washing machines equipped with multiple washing drums meet the washing needs of users for different clothes. However, each drum often becomes an independent, closed, and humid space after operation. When users forget to take out their clothes, the clothes left behind in the humid environment are very prone to bacterial growth and cross-odors.

[0003] In related technologies, although some washing machines are equipped with fresh air design schemes, they cannot effectively control the flow of fresh air. Utility Model Content

[0004] To overcome the problems existing in the related technologies, this disclosure provides a garment processing device.

[0005] According to an embodiment of this disclosure, a garment processing apparatus is provided, the garment processing apparatus comprising: At least two cylinders; Fresh air system, including air intake device and fresh air duct; The air intake device includes an air inlet for communicating with the outside of the garment processing equipment, and the air intake device is connected to the inside of the cylinder through the fresh air duct; wherein, the fresh air duct is provided with a valve.

[0006] The system utilizes an air intake device and a fresh air duct to introduce dry, fresh air from outside the washing machine into the sealed drum, thus supplying fresh air to the drum. Clothes remaining inside the drum are thus less damp under the influence of this fresh air, reducing the possibility of bacterial growth and odor. Secondly, the air intake device connects to at least two drums via the fresh air duct, enabling it to supply fresh air to at least two drums, achieving a "one-to-many" fresh air supply effect. This reduces the internal space occupied in multi-drum washing machines; furthermore, fewer components effectively reduce the failure rate and improve reliability. Additionally, by incorporating valves in the fresh air duct, the flow rate of fresh air entering the drum can be effectively regulated, meeting the needs for fresh air flow control.

[0007] In some possible implementations, the valve component includes a valve body, a drive motor, and a damper plate; The valve housing is provided with a first open side and a second open side. The first open side is connected to the air inlet device and communicates with its air outlet. The second open side is connected to and communicates with the fresh air duct. The drive motor is disposed on the outer wall of the valve housing, and the damper plate is rotatably disposed inside the valve housing and is connected to the drive motor for transmission.

[0008] The valve housing has two open sides for connecting to the outlet of the air inlet device and the inlet of the fresh air duct, respectively, thus achieving channel connectivity. Specific connection methods include, for example, pipe clamps, but this disclosure does not limit the specific connection method. Secondly, the drive motor drives the damper plate located within the valve housing to rotate, thereby regulating the flow rate of fresh air. However, this disclosure does not limit the specific structure of the valve components.

[0009] In some possible implementations, a first seal is provided between the first open side and the air inlet device; and / or, a second seal is provided between the second open side and the fresh air duct.

[0010] By setting the aforementioned first and / or second sealing elements, the fresh air duct, valve components, and air intake device are sealed and connected, thereby improving the sealing performance.

[0011] In some possible implementations, the valve housing is provided with at least one connecting post, the connecting post having a post hole formed inside, and the drive motor is provided with at least one motor lug, the motor lug having a motor connection hole. The second fastener passes through the post hole and the motor connection hole to connect the motor lug and the connecting post.

[0012] Specifically, by setting a connecting post on the valve body and a motor lug on the drive motor, the motor lug and the connecting post are connected by a second fastener, thereby connecting the drive motor to the valve body.

[0013] In some possible implementations, the valve component further includes a connecting shaft; One end of the connecting shaft is formed with a first shaft groove, and the motor shaft of the drive motor is inserted into the first shaft groove and is connected to the connecting shaft for transmission. The other end of the connecting shaft is formed with a shaft rod, and the damper plate is formed with a second shaft groove. The shaft rod is inserted into the second shaft groove and is connected to the damper plate in a driving connection.

[0014] One end of the connecting shaft has a first shaft groove that engages with the motor shaft of the drive motor, thereby achieving a transmission connection between the motor shaft and the connecting shaft. The other end of the connecting shaft has a shaft rod that engages with a second shaft groove on the damper plate, achieving a transmission connection between the connecting shaft and the damper plate and improving transmission stability.

[0015] In some possible implementations, the air inlet device and the upper cover of the housing are spaced apart by a first gap in the vertical direction; wherein, at least one of the drive motors of the valve component is disposed within the first gap; and / or, The air inlet device and the front panel of the housing are provided with a second gap in the front-to-back direction; wherein, at least one of the drive motors of the valve component is disposed within the second gap.

[0016] Specifically, by utilizing the first gap between the air inlet device and the top cover plate to arrange the valve component's drive motor, the space of the first gap is effectively utilized, ensuring the installation arrangement of the drive motor. And / or, by utilizing the first gap between the air inlet device and the front panel to arrange the valve component's drive motor, the space of the second gap is effectively utilized, ensuring the installation arrangement of the drive motor.

[0017] In some possible implementations, at least two of the cylinders include a first cylinder and two second cylinders; The second cylinder is located above the first cylinder, and the two rotation axes of the two second cylinders are respectively located on both sides of the vertical plane where the rotation axis of the first cylinder is located; The outer diameter of the second cylinder is smaller than the outer diameter of the first cylinder; The fresh air duct includes a first fresh air duct and two second fresh air ducts. The first fresh air duct is connected to the interior of the first cylinder, and the second fresh air duct is connected to the interior of the corresponding second cylinder. The valve is provided in both the first fresh air duct and the two second fresh air ducts.

[0018] The system comprises two second tubs, each with a smaller outer diameter than the first tub. In practical use, the first tub can wash and dry large items of clothing, while the two second tubs can wash and dry smaller items. For example, one second tub can wash underwear, while the other can wash socks. This disclosure does not limit the specific usage scenarios.

[0019] Secondly, the rotation axes of the two second cylinders are located on either side of the vertical plane containing the rotation axis of the first cylinder, thus making full use of the two "corner spaces" on the upper left and upper right of the first cylinder. Furthermore, placing the two second cylinders diagonally above the first cylinder, compared to placing them directly above the first cylinder, lowers the center of gravity of the garment processing equipment, reduces swaying, and improves stability.

[0020] Furthermore, by placing the air inlet device between the two vertical planes where the two rotation axes of the two second cylinders are located, the "corner space" left between the two second cylinders can be effectively utilized without the need to arrange a new space to accommodate the air inlet device. On the other hand, it ensures that the distance from the fresh air duct to the two adjacent second cylinders is the same or similar, avoiding the impact on air supply effect due to excessive differences in the length of the fresh air duct.

[0021] In addition, both the first fresh air duct and the two second fresh air ducts are equipped with valves to regulate the flow of fresh air entering the first and second ducts, meeting the different fresh air requirements of each duct. For example, if the outer diameter of the second duct is smaller than that of the first duct, the fresh air requirement in the second duct can be smaller, while the fresh air requirement in the first duct can be larger. This can be achieved by adjusting the valves on the second fresh air ducts, for example, by keeping the valves partially open to reduce the amount of fresh air entering the second duct. Similarly, adjusting the valves on the first fresh air ducts within the first duct, for example, by keeping the valves fully open, ensures the amount of fresh air entering the first duct.

[0022] In some possible implementations, the air inlet device is located between two vertical planes containing the two rotation axes of the two second cylinders, and the air inlet device is arranged above the horizontal plane containing the rotation axes of the second cylinders; or, The air inlet device is located between two vertical planes containing the two rotation axes of the two second cylinders, and the air inlet device is arranged below the horizontal plane containing the rotation axes of the second cylinders and above the first cylinder.

[0023] The air intake device is installed in the space above the rotation axis of the second cylinder. The air inlet of this device can also be located in the upper area to avoid drawing in dust from the ground if the device is installed too low. Furthermore, the placement of this air intake device allows for convenient maintenance and other operations, improving the user experience; or... The air intake device is arranged in the space below the rotation axis of the second cylinder, and this air intake device can be located above the first cylinder, effectively utilizing the vertical space between the first and second cylinders. Secondly, placing the air intake device between the first and second cylinders lowers the equipment's center of gravity. During high-level dehydration, a lower center of gravity generates a stronger stabilizing torque, effectively suppressing equipment swaying and misalignment. Furthermore, arranging the air intake device towards the center frees up space for components that must be located at the top, optimizing the spatial layout.

[0024] In addition, from the perspective of air duct layout, the air inlet device is arranged close to the two second cylinders and the first cylinder. Whether it is connected to the two second cylinders or the first cylinder through the fresh air duct, the length of the fresh air duct 22 can be minimized, reducing wind resistance and improving air supply efficiency.

[0025] In some possible implementations, two of the air outlets of the air inlet device are located on opposite sides of the vertical plane containing the rotation axis of the first cylinder, and the two second fresh air pipes are respectively connected to the corresponding air outlets through the valve components; The two valves corresponding to the two second fresh air ducts are arranged symmetrically about the vertical plane of the rotation axis of the first cylinder.

[0026] Among them, the two valve components corresponding to the two fresh air ducts are arranged symmetrically about the vertical plane of the rotation axis of the first cylinder, so that the two second fresh air ducts can be shared when they are arranged.

[0027] In some possible implementations, an overflow hole is formed on the upper rear side of the cylinder, which is used to overflow water inside the cylinder and to discharge gas inside the cylinder to form a fresh air outlet.

[0028] The design simplifies the structure by utilizing the overflow holes on the cylinder to exhaust the fresh air supplied into the cylinder, eliminating the need for new fresh air outlets.

[0029] The technical solutions provided by the embodiments of this disclosure can include the following beneficial effects: Firstly, the air inlet device and fresh air duct allow dry, fresh air from outside the garment processing equipment to be introduced into the sealed drum, thereby achieving the purpose of supplying fresh air into the drum. Clothes remaining in the drum can have their dampness improved under the action of the fresh air, reducing the possibility of bacterial growth and odor generation. Secondly, the air inlet device is connected to at least two drums via the fresh air duct, meaning it can supply fresh air to at least two drums, achieving a "one-to-many" fresh air supply effect. On the one hand, this reduces the internal space occupied in multi-drum washing machines; on the other hand, fewer components effectively reduce the failure rate and improve reliability. Furthermore, by installing valves in the fresh air duct, the flow rate of fresh air input into the drum can be effectively regulated, meeting the needs for fresh air flow control.

[0046] In the above technical solution, firstly, the air inlet device 21 and the fresh air duct 22 can introduce dry, fresh air from outside the clothes handling equipment into the sealed drum 1, thereby achieving the purpose of supplying fresh air into the drum 1. The clothes remaining in the drum 1 can improve their dampness under the action of fresh air, reducing the possibility of bacterial growth and odor generation. Secondly, the air inlet device 21 is connected to at least two drums 1 through the fresh air duct 22, that is, it can supply fresh air to at least two drums 1, achieving the effect of "one-to-many" fresh air supply. On the one hand, it can reduce the internal space occupied in multi-drum washing machines; on the other hand, fewer components can effectively reduce the failure rate and improve reliability. In addition, by setting a valve 23 in the fresh air duct 22, the flow rate of fresh air input into the drum 1 can be effectively regulated to meet the needs of fresh air flow control.

[0047] Among them, reference Figure 1 As shown, the air inlet 211 of the air inlet device 21 is arranged facing forward and is located between the two vertical planes where the two rotation axes of the two second cylinders 12 are located, and is arranged above the horizontal plane where the rotation axes of the second cylinders 12 are located.

[0048] Or, refer to Figure 2 As shown, the air inlet 211 of the air inlet device 21 is arranged rearward and is located between the two vertical planes where the two rotation axes of the two second cylinders 12 are located, and is arranged above the horizontal plane where the rotation axes of the second cylinders 12 are located.

[0049] Or, refer to Figure 3 As shown, the air inlet 211 of the air inlet device 21 is arranged upwards and is located between the two vertical planes where the two rotation axes of the two second cylinders 12 are located, and is arranged above the horizontal plane where the rotation axes of the second cylinders 12 are located.

[0050] Or, refer to Figure 4 As shown, the air inlet 211 of the air inlet device 21 is arranged facing forward and is located between the two vertical planes where the two rotation axes of the two second cylinders 12 are located, and is arranged below the horizontal plane where the rotation axis of the second cylinder 12 is located and above the first cylinder 11.

[0051] This disclosure does not limit the specific arrangement of the air intake device 21.

[0052] Optionally, refer to Figures 5 to 10 As shown, the valve component 23 includes a valve housing 231, a drive motor 232, and a damper plate 233. The valve housing 231 is provided with a first open side and a second open side. The first open side is connected to the air inlet device 21 and communicates with its air outlet. The second open side is connected to and communicates with the fresh air duct 22. The drive motor 232 is disposed on the outer wall of the valve housing 231. The damper plate 233 is rotatably disposed inside the valve housing 231 and is connected to the drive motor 232 for transmission.

[0053] In this embodiment, the two open sides of the valve housing 231 are respectively used to connect with the outlet of the air inlet device 21 and the inlet of the fresh air duct 22 to achieve channel connectivity. Specific connection methods include, for example, using pipe clamps to achieve connectivity, but this disclosure does not limit the specific connection method. Secondly, the drive motor 232 is used to drive the damper plate 233 disposed within the valve housing 231 to rotate, thereby regulating the flow rate of fresh air. However, this disclosure does not limit the specific structure of the valve component 23.

[0054] In one embodiment, a first seal (not shown) is provided between the first open side and the air inlet device 21; and / or, a second seal (not shown) is provided between the second open side and the fresh air duct 22.

[0055] By setting the aforementioned first and / or second sealing elements, a sealed connection is achieved between the fresh air duct 22, the valve 23, and the air inlet device 21, thereby improving sealing performance. For example, the first sealing element can be a first elastic sealing ring, which is compressed and disposed between the first open side and the sealing surface of the air inlet device 21; and / or, the second sealing element can be a second elastic sealing ring, which is compressed and disposed between the second open side and the sealing surface of the fresh air duct 22.

[0056] In another embodiment, see figure Figure 5 and Figure 6 As shown, the valve body 231 is provided with at least one connecting post 2311, and the connecting post 2311 has a post hole formed inside. The drive motor 232 is provided with at least one motor lug 2321, and the motor lug 2321 has a motor connection hole. The second fastener passes through the post hole and the motor connection hole to connect the motor lug 2321 and the connecting post 2311.

[0057] In this embodiment, a connecting post 2311 is provided on the valve housing 231, and a motor lug 2321 is provided on the drive motor 232. The motor lug 2321 and the connecting post 2311 are connected using a second fastener, thereby connecting the drive motor 232 to the valve housing 231. However, this disclosure does not limit the specific connection method of the drive motor 232 to the valve housing 231. In other embodiments, for example, the drive motor 232 can also be connected to the valve housing 231 by means of snap-fit ​​or other methods.

[0058] In other implementations, refer to Figure 7 , Figure 9 as well as Figure 10 As shown, the valve component 23 also includes a connecting shaft 234; one end of the connecting shaft 234 has a first shaft groove 2340, the motor shaft of the drive motor 232 is inserted into the first shaft groove 2340 and is connected to the connecting shaft 234 in a transmission manner; the other end of the connecting shaft 234 has a shaft rod 2341, the damper plate 233 has a second shaft groove 2330, the shaft rod 2341 is inserted into the second shaft groove 2330 and is connected to the damper plate 233 in a transmission manner.

[0059] In this embodiment, one end of the connecting shaft 234 has a first shaft groove 2340 that engages with the motor shaft of the drive motor 232, thereby achieving a transmission connection between the motor shaft of the drive motor 232 and the connecting shaft 234. Additionally, the other end of the connecting shaft 234, the shaft rod 2341, engages with a second shaft groove 2330 on the damper plate 233, achieving a transmission connection between the connecting shaft 234 and the damper plate 233, thus improving transmission stability. The shaft rod 2341 can have a T-shaped cross-section, and the second shaft groove 2330 can also have a matching T-shape cross-section to prevent relative rotation between the connecting shaft 234 and the damper plate 233. However, this disclosure does not limit the specific connection method between the connecting shaft 234 and the drive motor 232 and the damper plate 233.

[0060] Optionally, a first gap (not shown) is provided between the air inlet device 21 and the upper cover plate of the housing in the vertical direction; wherein, at least one drive motor 232 of the valve component 23 is disposed within the first gap. By utilizing the first gap between the air inlet device 21 and the upper cover plate to arrange the drive motor 232 of the valve component 23, the space of the first gap is effectively utilized, ensuring the installation arrangement of the drive motor 232.

[0061] In another implementation, refer to Figure 4 As shown, a second gap 2102 is provided between the air inlet device 21 and the front panel 4 of the housing in the front-rear direction; wherein, at least one drive motor 232 of the valve component 23 is disposed within the second gap 2102. By utilizing the second gap 2102 between the air inlet device 21 and the front panel 4 to arrange the drive motor 232 of the valve component 23, the space of the second gap 2102 is effectively utilized, ensuring the installation arrangement of the drive motor 232.

[0062] Optionally, refer to Figure 1 and Figure 3 As shown, at least two cylinders 1 include a first cylinder 11 and two second cylinders 12; the second cylinders 12 are located above the first cylinder 11, and the two rotation axes of the two second cylinders 12 are respectively located on both sides of the vertical plane where the rotation axis of the first cylinder 11 is located; the outer diameter of the second cylinder 12 is smaller than the outer diameter of the first cylinder; the fresh air duct 22 includes a first fresh air duct 221 and two second fresh air ducts 222, the first fresh air duct 221 is connected to the interior of the first cylinder 11, and the second fresh air duct 222 is connected to the interior of the corresponding second cylinder 12; wherein, the first fresh air duct 221 and the two second fresh air ducts 222 are all provided with valve components 23.

[0063] In this embodiment, firstly, there are two second tubular bodies 12, and the outer diameter of the second tubular body 12 is smaller than the outer diameter of the first tubular body 11. Therefore, in specific use, the first tubular body 11 can wash and dry large items of clothing, while the two second tubular bodies 12 can wash and dry small items of clothing. For example, one second tubular body 12 can wash a user's underwear, while the other second tubular body 12 can wash socks. Of course, this disclosure does not limit the specific usage scenario.

[0064] Secondly, the rotation axes of the two second cylinders 12 are located on both sides of the vertical plane containing the rotation axis of the first cylinder 11, thus making full use of the two "corner spaces" at the upper left and upper right of the first cylinder 11. Furthermore, arranging the two second cylinders 12 diagonally above the first cylinder 11, compared to arranging them directly above the first cylinder 11, lowers the center of gravity of the garment processing equipment, reduces swaying, and improves stability.

[0065] Furthermore, by placing the air inlet device 21 between the two vertical planes where the two rotation axes of the two second cylinders 12 are located, the "corner space" left between the two second cylinders 12 can be effectively utilized without the need to arrange a new space to accommodate the air inlet device 21. On the other hand, it ensures that the distance between the fresh air duct 22 and the two adjacent second cylinders 12 is the same or similar, avoiding the impact on the air supply effect due to excessive differences in the length of the fresh air duct 22.

[0066] Furthermore, both the first fresh air duct 221 and the two second fresh air ducts 222 are equipped with valves 23, which allow for the regulation of the fresh air flow entering the first cylinder 11 and the second cylinder 12 to meet the different fresh air usage needs of different cylinders 1. For example, if the outer diameter of the second cylinder 12 is smaller than the outer diameter of the first cylinder 11, the fresh air demand in the second cylinder 12 can be smaller, while the fresh air demand in the first cylinder 11 can be larger. This can be achieved by adjusting the valves 23 on the second fresh air duct 222, for example, by keeping the valves 23 in a half-open state to reduce the amount of fresh air entering the second cylinder 12. Conversely, adjusting the valves 23 on the first fresh air duct 221 of the first cylinder 11, for example, by keeping the valves 23 in a fully open state, ensures the amount of fresh air entering the first cylinder 11.

[0067] In one implementation, reference is made to Figures 1 to 3 As shown, the air inlet device 21 is located between two vertical planes containing the two rotation axes of the two second cylinders 12, and the air inlet device 21 is arranged above the horizontal plane containing the rotation axes of the second cylinders 12.

[0068] That is, the air intake device 21 is arranged in the space above the rotation axis of the second cylinder 12. The air inlet 211 of the air intake device 21 can also be arranged in the upper area to avoid the intake of dust and other particles from the ground due to the low placement. In addition, the position of the air intake device 21 makes it convenient for users to perform maintenance and other operations, thus improving the user experience.

[0069] In another embodiment, refer to Figure 4 As shown, the air inlet device 21 is located between two vertical planes containing the two rotation axes of the two second cylinders 12, and the air inlet device 21 is arranged below the horizontal plane containing the rotation axes of the second cylinders 12 and above the first cylinder 11.

[0070] That is, the air inlet device 21 is arranged in the space below the rotation axis of the second cylinder 12, and the air inlet device 21 can be located above the first cylinder 11, effectively utilizing the vertical space of the first cylinder 11 and the second cylinder 12. Secondly, arranging the air inlet device 21 between the first cylinder 11 and the second cylinder 12 can lower the center of gravity of the equipment. When the equipment is undergoing high-level dehydration, a lower center of gravity can generate a stronger stabilizing torque, effectively suppressing the shaking and "displacement" of the equipment. Furthermore, arranging the air inlet device 21 towards the central area frees up space for components that must be placed at the top, optimizing the spatial layout.

[0071] In addition, from the perspective of air duct layout, the air inlet device 21 is arranged close to the two second cylinders 12 and the first cylinder 11. Whether it is connected to the two second cylinders 12 or the first cylinder 11 through the fresh air duct 22, the length of the fresh air duct 22 can be minimized, reducing wind resistance and improving air supply efficiency.

[0072] Optionally, two of the air outlets of the air inlet device 21 are located on both sides of the vertical plane where the rotation axis of the first cylinder 11 is located, and two second fresh air pipes 222 are connected to the corresponding air outlets through valve components 23; wherein, the two valve components 23 corresponding to the two second fresh air pipes 222 are arranged symmetrically about the vertical plane where the rotation axis of the first cylinder 11 is located.

[0073] In this embodiment, the two valve components 23 corresponding to the two second fresh air ducts 222 are arranged symmetrically about the vertical plane of the rotation axis of the first cylinder 11. Therefore, the two second fresh air ducts 222 can be shared when arranged. For example, the second fresh air ducts 222 can be corrugated pipes, and only two corrugated pipes of the same model need to be assembled, which simplifies the assembly of the two second fresh air ducts 222.

[0074] Optionally, refer to Figure 1 As shown, the garment processing equipment also includes a drying pipe 51 that is connected to the interior of the drum 1, and a fresh air pipe 22 that is connected to the corresponding drying pipe 51 of the drum 1.

[0075] In this embodiment, the drying pipe 51 of the cylinder 1 is used to supply fresh air into the interior of the cylinder 1, eliminating the need for openings in the cylinder 1 and effectively simplifying the structure. For example, a connecting hole can be opened in the drying pipe 51, and the fresh air pipe 22 is sealed to the connecting hole. In addition, when the fresh air mechanism 2 is working, the drying mechanism 5 corresponding to the cylinder 1 can be in a non-working state, and fresh air can be supplied into the cylinder 1 through the drying pipe 51 in the drying mechanism 5.

[0076] In another embodiment, refer to Figure 1As shown, the cylinder 1 has an overflow hole 6, which is used to overflow water inside the cylinder 1 and to discharge gas inside the cylinder 1 to form a fresh air outlet.

[0077] That is, in this embodiment, the fresh air delivered to the cylinder 1 can be discharged by using the overflow hole 6 on the cylinder 1, without the need to open a new fresh air outlet, which simplifies the design of the structure.

[0078] For example, the aforementioned drying pipe 51 can be connected to the front side of the interior of the drum 1, that is, fresh air can enter from the front side of the interior of the drum 1, and the overflow hole 6 can be arranged above the rear side of the drum 1. In this way, when the fresh air enters the front side of the drum 1, it flows backward and is discharged from the overflow hole 6 on the rear side, so that the fresh air flows from front to back in the drum 1 to blow on the clothes in the drum 1, reducing the risk of bacteria growth and odor generation in the clothes in the drum 1.
