Description

Technical Field

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

[0002] In related technologies, clothing processing equipment includes a housing and multiple processing cylinders disposed within the housing. The multiple processing cylinders are used to process different types of clothing separately, making it convenient to classify and process clothing.

[0003] However, clothing handling equipment in related technologies is prone to eccentricity during operation, which is detrimental to overall balance, shock absorption, and stability, thus reducing the user experience. Summary of the Invention

[0004] This disclosure aims to at least partially address one of the technical problems in the related art.

[0005] Therefore, embodiments of this disclosure propose a garment processing device that is non-eccentric, facilitates shock absorption, and has high balance and stability.

[0006] The garment processing device of this disclosure includes: a housing; a first processing cylinder and a second processing cylinder, the first processing cylinder and the second processing cylinder being disposed inside the housing and arranged at a distance in the left-right direction, at least a portion of the first processing cylinder being rotatable relative to the housing, at least a portion of the second processing cylinder being rotatable relative to the housing, and the first processing cylinder and the second processing cylinder rotating in opposite directions.

[0007] The garment processing apparatus of this disclosure, by having a first processing cylinder and a second processing cylinder arranged at intervals in the left-right direction within the housing, facilitates the sorting and placement of different garments into the first and second processing cylinders for processing. By setting the rotation directions of the first and second processing cylinders to be opposite, the vibrations of the first and second processing cylinders during rotation will cancel each other out or weaken, preventing eccentricity during operation of the garment processing apparatus, thus improving shock absorption and enhancing the balance and stability of the garment processing apparatus.

[0008] In some embodiments, when the rotational speed of the first processing cylinder and the rotational speed of the second processing cylinder are both equal to or higher than a preset rotational speed threshold N, the rotational direction of the first processing cylinder and the rotational direction of the second processing cylinder are opposite.

[0009] In the garment processing device of this disclosure, since the vibration of the processing drum is mainly caused by the high-speed rotation of the processing drum, the rotation direction of the first processing drum and the rotation direction of the second processing drum are controlled to be opposite when the rotation speed of the first processing drum and the second processing drum are both equal to or higher than the preset rotation speed threshold N. This makes the vibration of the first processing drum during high-speed rotation cancel or weaken the vibration of the second processing drum during high-speed rotation, thereby improving the balance and stability of the garment processing device.

[0010] In some embodiments, the first processing cylinder is located to the left of the second processing cylinder, the first processing cylinder rotates clockwise, and the second processing cylinder rotates counterclockwise.

[0011] In the clothing processing device of this embodiment, the first processing cylinder on the left rotates clockwise at high speed, causing the clothing inside the first processing cylinder to come closer to the center of the casing, and the second processing cylinder on the right rotates counterclockwise at high speed, causing the clothing inside the second processing cylinder to come closer to the center of the casing. Thus, the clothing in the first processing cylinder and the clothing in the second processing cylinder come closer to the casing at the same time, so that the vibrations generated by the first processing cylinder and the vibrations generated by the second processing cylinder are more concentrated towards the center of the casing, which is beneficial to the vibration reduction and balance of the clothing processing device.

[0012] In some embodiments, when only one of the first processing cylinder and the second processing cylinder has a rotational speed equal to or higher than a preset rotational speed threshold N, the rotational direction of the first processing cylinder and the rotational direction of the second processing cylinder are opposite or the same.

[0013] In the garment processing apparatus of this disclosure, when the rotational speed of one and only one of the first and second processing drums is equal to or higher than a preset rotational speed threshold N, although the vibration of the processing drum with the higher rotational speed (equal to or higher than the preset rotational speed threshold N) is greater during rotation, the vibration of the processing drum with the lower rotational speed (lower than the preset rotational speed threshold N) is smaller during rotation. The impact on the shock absorption and balance of the garment processing apparatus is relatively small. The rotational directions of the processing drums can be the same or opposite, thereby improving the flexibility and adaptability of the garment processing procedure.

[0014] In some embodiments, the first processing cylinder is located to the left of the second processing cylinder, and the first processing cylinder rotates clockwise only when the rotational speed of the first processing cylinder is equal to or higher than a preset rotational speed threshold N, and the second processing cylinder rotates clockwise or counterclockwise.

[0015] The garment processing device of this disclosure sets the first processing drum, which has a rotation speed equal to or higher than a preset rotation speed threshold N and is located on the left side, to rotate clockwise. This causes the garments inside the first processing drum to come closer to the center of the machine casing. Meanwhile, the second processing drum has a relatively low rotation speed and less vibration during rotation. This has a relatively small impact on the shock absorption and balance of the garment processing device. Therefore, the rotation direction of the second processing drum is not restricted, which is beneficial for the shock absorption and balance of the garment processing device while improving the flexibility and adaptability of the garment processing procedure.

[0016] In some embodiments, the first processing cylinder is located to the left of the second processing cylinder, and the second processing cylinder rotates counterclockwise only when the rotational speed of the second processing cylinder is equal to or higher than a preset rotational speed threshold N, while the first processing cylinder rotates clockwise or counterclockwise.

[0017] The garment processing device of this disclosure sets the second processing drum, which has a rotation speed equal to or higher than a preset rotation speed threshold N and is located on the right side, to rotate counterclockwise. This causes the garments inside the second processing drum to come closer to the center of the machine casing. Meanwhile, the first processing drum has a relatively low rotation speed and less vibration during rotation, which has a relatively small impact on the shock absorption and balance of the garment processing device. Therefore, the rotation direction of the first processing drum is not restricted, which is beneficial for the shock absorption and balance of the garment processing device while improving the flexibility and adaptability of the garment processing procedure.

[0018] In some embodiments, when the rotational speed of the first processing cylinder and the rotational speed of the second processing cylinder are both lower than a preset rotational speed threshold N, the rotational direction of the first processing cylinder and the rotational direction of the second processing cylinder are opposite or the same.

[0019] In the garment processing apparatus of this disclosure, when the rotational speeds of both the first and second processing drums are low (both below a preset rotational speed threshold N), the vibration during the rotation of the first processing drum is very small, and the vibration during the rotation of the second processing drum is also very small. Therefore, it is not necessary to limit the rotational direction of the first and second processing drums, which can reduce the complexity of the garment processing procedure and improve flexibility and adaptability.

[0020] In some embodiments, the preset rotation speed threshold N is the rotation speed of the corresponding processing drum during the dehydration process.

[0021] In the garment processing device of this disclosure, the rotation speed of the processing drum is relatively high during the dehydration process, which has a significant impact on the overall balance and stability. By limiting the preset rotation speed threshold N to the dehydration process of the processing drum, it is convenient to adjust the rotation direction in a timely manner when the processing drum is in the dehydration process and the rotation speed is high (equal to or higher than the preset rotation speed threshold N), thereby improving the balance and stability of the garment processing device.

[0022] In some embodiments, the preset rotation speed threshold N is the rotation speed at which the clothes inside the processing drum are in contact with the inner wall of the processing drum when the corresponding processing drum rotates.

[0023] In the garment processing device of this disclosure, the rotation speed of the processing drum is relatively high when the garments inside the processing drum are in contact with the inner wall of the processing drum during rotation, which has a significant impact on the overall balance and stability. By limiting the preset rotation speed threshold N to the rotation speed when the garments are in contact with the inner wall of the processing drum, it is convenient to adjust the rotation direction of the processing drum in a timely manner, thereby improving the balance and stability of the garment processing device.

[0024] In some embodiments, the preset speed threshold N is ≥ 70 r / min. This is achieved by setting the preset speed threshold N to be greater than or equal to 70 r / min.

[0025] In the clothing processing device of this embodiment, when the preset rotation speed threshold N of the processing drum is ≥70 r / min, the clothing can adhere to the inner wall of the processing drum during the rotation process, thereby improving the cleaning effect. At this time, the rotation speed of the processing drum is relatively high, which has a significant impact on the overall balance and stability. Therefore, adjusting the rotation direction of the first processing drum and the rotation direction of the second processing drum can improve the balance and stability of the clothing processing device.

[0026] In some embodiments, the preset rotational speed threshold N > 150 r / min.

[0027] In the clothing processing device of this embodiment, the relatively small-capacity processing drum can only adhere to the inner wall of the drum during rotation when the processing drum reaches a relatively high speed. By setting the preset speed threshold N to be greater than 150 r / min, the speed at which the clothing adheres to the inner wall of the drum during rotation can be adapted to the relatively small-capacity processing drum, thereby improving the adaptability, balance and stability of the clothing processing device.

[0028] In some embodiments, both the first processing cylinder and the second processing cylinder have an inlet, the center height of which is H1, wherein when 600mm≤H1≤1000mm, the preset rotational speed threshold N is 800r / min≤N≤1500r / min.

[0029] The clothing processing device of this disclosure limits the relationship between the center height of the picking port and the preset rotation speed threshold N. When the center height of the picking port is relatively low and limited to between 600mm and 1000mm, in order to maintain balance and stability, the rotation speed of the processing cylinder can withstand a relatively high rotation speed and the preset rotation speed threshold N is limited to between 800r / min and 1500r / min. This adjusts the rotation direction of the processing cylinder so that the vibration generated by the processing cylinder is minimized, thereby improving the user experience.

[0030] In some embodiments, when the center height of the object retrieval port is 1000mm < H1 ≤ 1400mm, the preset rotation speed threshold N < 800r / min.

[0031] In the clothing processing device of this disclosure, when the center height of the picking port is relatively high and limited to between 1000mm and 1400mm, in order to maintain balance and stability, the rotation speed of the processing drum can withstand a relatively low speed and the preset speed threshold N is limited to below 800r / min, so as to adjust the rotation direction of the processing drum, so that the vibration generated by the processing drum is as small as possible, thereby improving the user experience.

[0032] In some embodiments, the garment processing device further includes a third processing tube, with the first processing tube and the second processing tube located above the third processing tube, the capacity of the third processing tube being greater than the capacity of the first processing tube, and the capacity of the third processing tube being greater than the capacity of the second processing tube.

[0033] The clothing processing device of this embodiment improves the convenience of sorting and processing different types of clothing by providing a third processing cylinder. The third processing cylinder has the largest capacity and is located below the first and second processing cylinders, which helps to lower the center of gravity of the clothing processing device and makes the clothing processing device more stable during operation.

[0034] In some embodiments, the highest point of the third processing cylinder is higher than the lowest point of at least one of the first and second processing cylinders.

[0035] The garment processing device of this disclosure can make full use of the space above the left or right of the third processing tube by making the highest point of the third processing tube higher than the lowest point of at least one of the first and second processing tubes, thereby reducing the overall height of the first, second and third processing tubes. This reduces the overall height of the garment processing device, improves compactness, reduces space occupation, and lowers the center of gravity of the garment processing device, which is beneficial for overall balance and shock absorption.

[0036] In some embodiments, the first processing cylinder and the second processing cylinder are rigidly or rigidly connected, which improves the connection stability and firmness of the first processing cylinder and the second processing cylinder, and ensures that the overall shock absorption effect of the garment processing equipment is achieved by adjusting the rotation direction of the first processing cylinder and / or the second processing cylinder, thereby improving the user experience.

[0037] In some embodiments, the garment processing device further includes a fixing frame connected between the first processing tube and the second processing tube.

[0038] The garment processing apparatus of this disclosure has a fixing frame that can constrain the position of the first processing cylinder and the second processing cylinder, which helps to reduce the swaying amplitude of the first processing cylinder and the second processing cylinder when they rotate, thereby reducing the noise generated when the garment processing apparatus is working.

[0039] In some embodiments, the highest point of the fixing frame is lower than the highest point of the first processing cylinder and the highest point of the second processing cylinder, and the lowest point of the fixing frame is higher than the lowest point of the first processing cylinder and the lowest point of the second processing cylinder.

[0040] In the garment processing device of this embodiment, the upper surface of the fixing frame, the outer wall surface of the first processing cylinder, and the outer wall surface of the second processing cylinder together form a component accommodating space. This component accommodating space can be used to place components such as the drying module, the feeding module, the electronic control module, and the sterilization module, thereby making the overall structure of the garment processing device more compact and improving space utilization. The bottom surface of the fixing frame, the outer wall surface of the first processing cylinder, and the outer wall surface of the second processing cylinder together form a clearance space to avoid interference with the third processing cylinder during assembly.

[0041] In some embodiments, the housing has a suspension beam located above the first processing cylinder and the second processing cylinder, and the suspension beam is connected to the first processing cylinder and the second processing cylinder.

[0042] The garment processing device of this disclosure is connected to the first processing cylinder and the second processing cylinder by a suspension beam, which facilitates fixing the first processing cylinder and the second processing cylinder inside the machine housing and further improves the connection strength between the first processing cylinder and the second processing cylinder.

[0043] In some embodiments, the first processing cylinder, the second processing cylinder, and the third processing cylinder each have a retrieval port facing the front side of the housing.

[0044] The clothing processing device of this disclosure has the inlets of the first, second, and third processing drums all facing forward. The first, second, and third processing drums can all be drum-type processing drums, which makes it convenient for users to pick up and put in clothes from the front, while improving the washing and care effect of clothes and improving energy efficiency.

[0051] Embodiments of this disclosure are described in detail below, with examples of these embodiments illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this disclosure, and should not be construed as limiting it.

[0052] The following is a reference appendix. Figures 1 to 4 This disclosure describes a garment processing apparatus according to an embodiment of the present disclosure.

[0053] The garment processing apparatus of this disclosure includes a housing 1, a first processing cylinder 2, and a second processing cylinder 3. The first processing cylinder 2 and the second processing cylinder 3 are disposed inside the housing 1 and arranged at a distance from each other in the left-right direction. At least a portion of the first processing cylinder 2 is rotatable relative to the housing 1, and at least a portion of the second processing cylinder 3 is rotatable relative to the housing 1. The rotation directions of the first processing cylinder 2 and the second processing cylinder 3 are opposite.

[0054] Optionally, such as Figures 1-2 As shown, the first processing cylinder 2 and the second processing cylinder 3 are arranged at intervals in the left-right direction. This can be understood as the first processing cylinder 2 being located on the left and the second processing cylinder 3 being located on the right; or, the first processing cylinder 2 being located on the right and the second processing cylinder 3 being located on the left.

[0055] At least a portion of the first processing cylinder 2 is rotatable relative to the housing 1, and the rotation direction of the first processing cylinder 2 can be clockwise or counterclockwise. At least a portion of the second processing cylinder 3 is rotatable relative to the housing 1, and the rotation direction of the first processing cylinder 3 can be clockwise or counterclockwise.

[0056] The first processing cylinder 2 and the second processing cylinder 3 rotate in opposite directions: the first processing cylinder 2 rotates clockwise and the second processing cylinder 3 rotates counterclockwise; or, the first processing cylinder 2 rotates counterclockwise and the second processing cylinder 3 rotates clockwise.

[0057] When the first processing cylinder 2 and the second processing cylinder 3 rotate in the same direction, the clothes in the first processing cylinder 2 and the clothes in the second processing cylinder 3 will stick together in the same direction (to the left or to the right at the same time), causing the overall clothing processing equipment to be unbalanced, which is not conducive to shock absorption.

[0058] The garment processing device of this disclosure, by having a first processing cylinder 2 and a second processing cylinder 3 arranged at intervals in the left-right direction within the housing 1, facilitates the sorting and placement of different garments into the first processing cylinder 2 and the second processing cylinder 3 for processing. By setting the rotation directions of the first processing cylinder 2 and the second processing cylinder 3 to be opposite, the vibrations of the first processing cylinder 2 and the second processing cylinder 3 during rotation will cancel each other out or weaken each other, preventing eccentricity of the garment processing device during operation, which is beneficial for shock absorption and thus improves the balance and stability of the garment processing device.

[0059] In some embodiments, when the rotational speed of the first processing cylinder 2 and the rotational speed of the second processing cylinder 3 are both equal to or higher than a preset rotational speed threshold N, the rotational direction of the first processing cylinder 2 and the rotational direction of the second processing cylinder 3 are opposite.

[0060] Optionally, since the vibration of the processing cylinder is mainly caused by the high-speed rotation of the processing cylinder, when the rotation speed of the first processing cylinder 2 is equal to or higher than the preset rotation speed threshold N, and the rotation speed of the second processing cylinder 3 is equal to or higher than the preset rotation speed threshold N, the rotation direction of the first processing cylinder 2 and the rotation direction of the second processing cylinder 3 are controlled to be opposite, so that the vibration of the first processing cylinder 2 during high-speed rotation and the vibration of the second processing cylinder 3 during high-speed rotation cancel each other out or weaken each other, thereby improving the balance and stability of the clothing processing equipment.

[0061] Optionally, the first processing cylinder 2 rotates clockwise and the second processing cylinder 3 rotates counterclockwise; or, the first processing cylinder 2 rotates counterclockwise and the second processing cylinder 3 rotates clockwise.

[0062] In some embodiments, the first processing cylinder 2 is located to the left of the second processing cylinder 3, the first processing cylinder 2 rotates clockwise, and the second processing cylinder 3 rotates counterclockwise.

[0063] Optionally, such as Figures 1-2 As shown, the first processing cylinder 2 is located on the left and the second processing cylinder 3 is located on the right. Since the first processing cylinder 2 and the second processing cylinder 3 are arranged side by side from left to right, when the rotation speed of the first processing cylinder 2 is equal to or higher than the preset rotation speed threshold N, and the rotation speed of the second processing cylinder 3 is equal to or higher than the preset rotation speed threshold N, the first processing cylinder 2 on the left rotates clockwise at high speed, causing the clothes in the first processing cylinder 2 to come closer to the center of the casing 1, and the second processing cylinder 3 on the right rotates counterclockwise at high speed, causing the clothes in the second processing cylinder 3 to come closer to the center of the casing 1. The clothes in the first processing cylinder 2 and the clothes in the second processing cylinder 3 come closer to the casing 1 at the same time, so that the vibration generated by the first processing cylinder 2 and the vibration generated by the second processing cylinder 3 are more concentrated in the center of the casing 1, which is beneficial to the vibration reduction and balance of the clothing processing equipment.

[0064] In some embodiments, when the rotational speed of only one of the first processing cylinder 2 and the second processing cylinder 3 is equal to or higher than a preset rotational speed threshold N, the rotational direction of the first processing cylinder 2 and the rotational direction of the second processing cylinder 3 are either opposite or the same. This can be understood as follows: The rotational speed of the first processing cylinder 2 is equal to or higher than the preset rotational speed threshold N, and the rotational speed of the second processing cylinder 3 is lower than the preset rotational speed threshold N; the rotational direction of the first processing cylinder 2 and the rotational direction of the second processing cylinder 3 are the same. Alternatively, the rotational speed of the first processing cylinder 2 is equal to or higher than the preset rotational speed threshold N, and the rotational speed of the second processing cylinder 3 is lower than the preset rotational speed threshold N; the rotational direction of the first processing cylinder 2 and the rotational direction of the second processing cylinder 3 are opposite. Alternatively, the rotational speed of the first processing cylinder 2 is lower than the preset rotational speed threshold N, and the rotational speed of the second processing cylinder 3 is equal to or higher than the preset rotational speed threshold N; the rotational direction of the first processing cylinder 2 and the rotational direction of the second processing cylinder 3 are opposite.

[0065] In the garment processing apparatus of this disclosure, when only one of the first processing drum 2 and the second processing drum 3 has a rotational speed greater than or equal to a preset rotational speed threshold N, although the processing drum with a higher rotational speed (equal to or higher than the preset rotational speed threshold N) experiences greater vibration during rotation, the processing drum with a lower rotational speed (lower than the preset rotational speed threshold N) experiences less vibration during rotation. This has a relatively small impact on the shock absorption and balance of the garment processing apparatus. The rotation directions of the processing drums can be the same or opposite, thereby improving the flexibility and adaptability of the garment processing procedure.

[0066] In some embodiments, the first processing cylinder 2 is located to the left of the second processing cylinder 3. The first processing cylinder 2 rotates clockwise only when the rotational speed of the first processing cylinder 2 is equal to or higher than a preset rotational speed threshold N, and the second processing cylinder 3 rotates clockwise or counterclockwise.

[0067] Optionally, such as Figures 1-2 As shown, the first processing cylinder 2 is located on the left and the second processing cylinder 3 is located on the right. The first processing cylinder 2 and the second processing cylinder 3 are respectively located on both sides of the center of the housing 1. Since the first processing cylinder 2 and the second processing cylinder 3 are arranged side by side from left to right, when the rotation speed of the first processing cylinder 2 is equal to or higher than the preset rotation speed threshold N, and the rotation speed of the second processing cylinder 3 is lower than the preset rotation speed threshold N, by setting the first processing cylinder 2 located on the left to rotate clockwise, the clothes in the first processing cylinder 2 are brought closer to the center of the housing 1. The rotation speed of the second processing cylinder 3 is relatively low, and the vibration during the rotation process is small. The impact on the shock absorption and balance of the clothing processing equipment is relatively small. Therefore, the rotation direction of the second processing cylinder 3 is not restricted, which is beneficial to the shock absorption and balance of the clothing processing equipment, while improving the flexibility and adaptability of the clothing processing program.

[0068] When the first processing cylinder 2 rotates clockwise and the second processing cylinder 3 rotates counterclockwise, the clothes in the first processing cylinder 2 and the clothes in the second processing cylinder 3 move closer to the center of the housing 1. As a result, the clothes in the first processing cylinder 2 and the clothes in the second processing cylinder 3 move closer to the center of the housing 1, so that the vibrations generated by the first processing cylinder 2 and the second processing cylinder 3 are more concentrated in the center of the housing 1, thus helping to reduce the vibration of the clothing processing equipment.

[0069] In some embodiments, the first processing cylinder 2 is located to the left of the second processing cylinder 3. The second processing cylinder 3 rotates counterclockwise only when the rotational speed of the second processing cylinder 3 is equal to or higher than a preset rotational speed threshold N, and the first processing cylinder 2 rotates clockwise or counterclockwise.

[0070] Optionally, such as Figures 1-2 As shown, the first processing cylinder 2 is located on the left and the second processing cylinder 3 is located on the right. The first processing cylinder 2 and the second processing cylinder 3 are respectively located on both sides of the center of the housing 1. Since the first processing cylinder 2 and the second processing cylinder 3 are arranged side by side from left to right, when the rotation speed of the second processing cylinder 3 is equal to or higher than the preset rotation speed threshold N, and the rotation speed of the first processing cylinder 2 is lower than the preset rotation speed threshold N, by setting the second processing cylinder 3 located on the right to rotate counterclockwise, the clothes in the second processing cylinder 3 are brought closer to the center of the housing 1. The rotation speed of the first processing cylinder 2 is relatively low, and the vibration during the rotation process is small, so the impact on the shock absorption and balance of the clothing processing equipment is relatively small. Therefore, the rotation direction of the first processing cylinder 2 is not restricted, which is beneficial to the shock absorption and balance of the clothing processing equipment, while improving the flexibility and adaptability of the clothing processing program.

[0071] When the second processing cylinder 3 rotates counterclockwise and the first processing cylinder 2 rotates clockwise, the clothes in the second processing cylinder 3 and the clothes in the first processing cylinder 2 move closer to the center of the housing 1. As a result, the clothes in the first processing cylinder 2 and the clothes in the second processing cylinder 3 move closer to the housing 1 at the same time, so that the vibrations generated by the first processing cylinder 2 and the second processing cylinder 3 are more concentrated in the center of the housing 1, thus helping to reduce the vibration of the clothing processing equipment.

[0072] In some embodiments, when the rotational speed of the first processing cylinder 2 and the rotational speed of the second processing cylinder 3 are both lower than a preset rotational speed threshold N, the rotational direction of the first processing cylinder 2 and the rotational direction of the second processing cylinder 3 are opposite or the same.

[0073] Optionally, the higher the rotation speed of the processing drum, the greater the vibration; correspondingly, the lower the rotation speed of the processing drum, the smaller the vibration. When the rotation speeds of the first processing drum 2 and the second processing drum 3 are both low (both below the preset rotation speed threshold N), the vibration during the rotation of the first processing drum 2 is very small, and the vibration during the rotation of the second processing drum 3 is also very small. There is no need to limit the rotation direction of the first processing drum 2 and the second processing drum 3, which can reduce the complexity of the clothing processing procedure and improve flexibility and adaptability.

[0074] Optionally, the rotation direction of the first processing cylinder 2 being the same as that of the second processing cylinder 3 includes: the first processing cylinder 2 rotating clockwise and the second processing cylinder 3 rotating clockwise; or, the first processing cylinder 2 rotating counterclockwise and the second processing cylinder 3 rotating counterclockwise. The rotation direction of the first processing cylinder 2 being opposite to that of the second processing cylinder 3 includes: the first processing cylinder 2 rotating clockwise and the second processing cylinder 3 rotating counterclockwise; or, the first processing cylinder 2 rotating counterclockwise and the second processing cylinder 3 rotating clockwise.

[0075] In some embodiments, the preset rotation speed threshold N is the rotation speed of the corresponding processing drum during the dehydration process.

[0076] Optionally, the preset speed threshold N can be the speed at the start of dehydration or the speed during the dehydration process. During the dehydration program, the speed of the processing drum is relatively high, which has a significant impact on the overall balance and stability. By limiting the preset speed threshold N to the dehydration program of the processing drum, it is easier to adjust the rotation direction in a timely manner when the drum is in the dehydration program and the speed is high (equal to or higher than the preset speed threshold N), thereby improving the balance and stability of the garment processing equipment.

[0077] In some embodiments, the preset rotation speed threshold N is the rotation speed at which the clothes inside the processing drum are in contact with the inner wall of the processing drum when the corresponding processing drum rotates.

[0078] During the garment processing process, when the processing drum rotates at a low speed, the centrifugal force on the garment is small, and the garment floats in the water. When the processing drum rotates at a high speed, the centrifugal force on the garment increases, and under the action of the increased centrifugal force, the garment is pressed tightly against the inner wall of the processing drum, making it adhere to the inner wall of the processing drum.

[0079] In the garment processing device of this disclosure, the rotation speed of the processing drum is relatively high when the garments inside the processing drum are in contact with the inner wall of the processing drum during rotation, which has a significant impact on the overall balance and stability. By limiting the preset rotation speed threshold N to the rotation speed when the garments are in contact with the inner wall of the processing drum, it is convenient to adjust the rotation direction of the processing drum in a timely manner, thereby improving the balance and stability of the garment processing device.

[0080] In some embodiments, the preset rotational speed threshold N is ≥ 70 r / min.

[0081] Optionally, different capacity processing drums have different rotation speeds when the clothes are in contact with the inner wall of the processing drum during the clothing processing process. The smaller the capacity of the processing drum, the higher the rotation speed when the clothes are in contact with the inner wall of the processing drum. Conversely, the larger the capacity of the processing drum, the lower the rotation speed when the clothes are in contact with the inner wall of the processing drum.

[0082] In the clothing processing device of this embodiment, when the preset rotation speed threshold N of the processing drum is ≥70 r / min, the clothing can adhere to the inner wall of the processing drum during the rotation process, thereby improving the cleaning effect. At this time, the rotation speed of the processing drum is relatively high, which has a significant impact on the overall balance and stability. Therefore, the rotation direction of the first processing drum 2 and the rotation direction of the second processing drum 3 are adjusted to improve the balance and stability of the clothing processing device.

[0083] Optionally, the preset speed threshold N is 70-80 r / min.

[0084] In some embodiments, the preset rotational speed threshold N > 150 r / min.

[0085] In the clothing processing device of this embodiment, the relatively small-capacity processing drum can only adhere to the inner wall of the drum during rotation when the processing drum reaches a relatively high speed. By setting the preset speed threshold N to be greater than 150 r / min, the speed at which the clothing adheres to the inner wall of the drum during rotation can be adapted to the relatively small-capacity processing drum, thereby improving the adaptability, balance and stability of the clothing processing device.

[0086] Optionally, the preset speed threshold N is greater than or equal to 180 r / min.

[0087] In some embodiments, both the first processing cylinder 2 and the second processing cylinder 3 have an extraction port 4, the center height of the extraction port 4 is H1, and when 600mm≤H1≤1000mm, the preset rotational speed threshold N is 800r / min≤N≤1500r / min.

[0088] Optionally, such as Figures 1-3 As shown, the retrieval ports 4 of both the first processing cylinder 2 and the second processing cylinder 3 are arranged facing forward, making it convenient for users to retrieve and place clothes daily. The distance between the center of the retrieval port 4 and the support surface of the casing 1 is the center height of the retrieval port 4. As the center height of the retrieval port 4 increases, the vibration amplitude of the clothing processing equipment that is acceptable to the user decreases.

[0089] The smaller the distance between the center of the retrieval port 4 and the supporting surface of the casing 1, that is, the lower the center height of the retrieval port 4, the lower the center of gravity of the processing cylinder, and the greater the user's tolerance for the vibration amplitude of the clothing processing equipment. Conversely, the larger the distance between the center of the retrieval port 4 and the supporting surface of the casing 1, that is, the higher the center height of the retrieval port 4, the higher the center of gravity of the processing cylinder, and the less the user's tolerance for the vibration amplitude of the clothing processing equipment.

[0090] The clothing processing device of this disclosure limits the relationship between the center height of the picking port 4 and the preset rotation speed threshold N. When the center height of the picking port 4 is relatively low and limited to between 600mm and 1000mm, in order to maintain balance and stability, the rotation speed of the processing cylinder can withstand a relatively high rotation speed and the preset rotation speed threshold N is limited to between 800r / min and 1500r / min. This adjusts the rotation direction of the processing cylinder, so that the vibration generated by the processing cylinder is minimized and the user experience is improved.

[0091] For example, H1 is 600mm, 700mm, 716mm, 800mm, 900mm, 1000mm. N is 800r / min, 900r / min, 1000r / min, 1100r / min, 1200r / min, 1500r / min.

[0092] In some embodiments, when the center height of the picking port 4 is 1000mm < H1 ≤ 1400mm, the preset rotation speed threshold N < 800r / min.

[0093] In the clothing processing device of this disclosure, when the center height of the picking port 4 is relatively high and limited to between 1000mm and 1400mm, in order to maintain balance and stability, the rotation speed of the processing drum can withstand a relatively low speed and the preset speed threshold N is limited to below 800r / min, so as to adjust the rotation direction of the processing drum, so that the vibration generated by the processing drum is as small as possible, thereby improving the user experience.

[0094] For example, H1 is 1100mm, 1200mm, 1300mm, 1400mm. N is 400r / min, 500r / min, 600r / min, 700r / min, 750r / min.

[0095] Optionally, the first processing cylinder 2 includes a first outer cylinder and a first inner cylinder disposed within the first outer cylinder, the first inner cylinder being rotatable relative to the first outer cylinder. The rotatability of at least a portion of the first processing cylinder 2 relative to the housing 1 means that the first inner cylinder is rotatable relative to both the first outer cylinder and the housing 1, and the rotation direction and speed of the first processing cylinder 2 are the same as the rotation direction and speed of the first inner cylinder.

[0096] The second processing cylinder 3 includes a second outer cylinder and a second inner cylinder disposed within the second outer cylinder, the second inner cylinder being rotatable relative to the second outer cylinder. The fact that at least a portion of the second processing cylinder 3 is rotatable relative to the housing 1 means that the second inner cylinder is rotatable relative to both the second outer cylinder and the housing 1, and the rotational direction and speed of the second processing cylinder 3 are the same as those of the second inner cylinder.

[0097] In some embodiments, the garment processing device further includes a third processing cylinder 5, with the first processing cylinder 2 and the second processing cylinder 3 located above the third processing cylinder 5. The capacity of the third processing cylinder 5 is greater than the capacity of the first processing cylinder 2, and the capacity of the third processing cylinder 5 is greater than the capacity of the second processing cylinder 3.

[0098] Optionally, such as Figures 1-2 As shown, the first processing cylinder 2 and the second processing cylinder 3 are located on the left and right sides of the third processing cylinder 5, respectively. That is, the first processing cylinder 2 is located on the upper left of the third processing cylinder 5, and the second processing cylinder 3 is located on the upper right of the third processing cylinder 5. The arrangement of the three processing cylinders allows users to process different clothes through three different processing cylinders, which expands the application range of the clothing processing equipment and improves the convenience of sorting and processing different clothes.

[0099] The capacity of the first processing cylinder 2 and the second processing cylinder 3 can be set to be the same or different. The third processing cylinder 5 has the largest capacity and is located below the first processing cylinder 2 and the second processing cylinder 3, which helps to lower the center of gravity of the clothing processing equipment and makes the clothing processing equipment more stable during operation.

[0100] For example, the first processing cylinder 2 and the second processing cylinder 3 are arranged symmetrically in the left and right directions. For another example, the distances of the first processing cylinder 2 and the second processing cylinder 3 from the axis of the third processing cylinder 5 in the left and right directions are approximately equal. On the one hand, this makes the structure of the clothing processing equipment more regular. On the other hand, it allows the center of gravity of the clothing processing equipment to be located approximately in the middle of the clothing processing equipment, which is beneficial to improving the stability of the clothing processing equipment during operation.

[0101] For example, the first processing cylinder 2 and the second processing cylinder 3 are the same size and shape, and the materials of the first processing cylinder 2 and the second processing cylinder 3 are interchangeable, which facilitates the assembly of clothing processing equipment, reduces production costs, and makes subsequent maintenance and replacement more convenient.

[0102] In other embodiments, the first processing cylinder 2 and the second processing cylinder 3 may also be different in size and shape.

[0103] In some embodiments, the highest point of the third processing cylinder 5 is higher than the lowest point of at least one of the first processing cylinder 2 and the second processing cylinder 3.

[0104] Optionally, such as Figures 1-2As shown, the highest point of the third processing cylinder 5 is higher than the lowest point of at least one of the first processing cylinder 2 and the second processing cylinder 3. This can be understood as the highest point of the third processing cylinder 5 being higher than the lowest point of the first processing cylinder 2, or the highest point of the third processing cylinder 5 being higher than the lowest point of the second processing cylinder 3, or the highest point of the third processing cylinder 5 being higher than the lowest point of the first processing cylinder 2 and higher than the lowest point of the second processing cylinder 3. When the highest point of the third processing cylinder 5 is higher than the lowest point of the first processing cylinder 2 and higher than the lowest point of the second processing cylinder 3, the first processing cylinder 2 and the second processing cylinder 3 are located diagonally above the third processing cylinder 5, rather than directly above the third processing cylinder 5.

[0105] Since the first processing cylinder 2 and the second processing cylinder 3 are arranged at intervals in the left and right direction and are both located above the third processing cylinder 5, and the highest point of the third processing cylinder 5 is higher than the lowest point of the first processing cylinder 2 and / or the second processing cylinder 3, the first processing cylinder 2 and the second processing cylinder 3 can make full use of the space above the left and / or the right of the third processing cylinder 5, reduce the overall height of the clothing processing equipment, make the structure of the clothing processing equipment compact, occupy less space, and facilitate the overall balance, shock absorption and stability.

[0106] like Figure 1 As shown, the first processing cylinder 2, the second processing cylinder 3, and the third processing cylinder 5 are generally cylindrical structures, and the housing 1 is generally cubic. Therefore, the upper left and upper right of the third processing cylinder 5 have certain accommodating spaces. By making the highest point of the third processing cylinder 5 higher than the lowest point of at least one of the first processing cylinder 2 and the second processing cylinder 3, the bottom of the first processing cylinder 2 and / or the second processing cylinder 3 can extend into the accommodating space enclosed by the outer side wall of the third processing cylinder 5 and the inner side wall of the housing 1, thereby reducing the overall height of the clothing processing equipment and lowering the center of gravity of the clothing processing equipment, which is beneficial to the overall balance and shock absorption.

[0107] like Figures 1-2 As shown, the lowest point of the first processing cylinder 2 is the highest point of the bottom surface of the first processing cylinder 2, the lowest point of the second processing cylinder 3 is the highest point of the bottom surface of the second processing cylinder 3, and the highest point of the third processing cylinder 5 is located on the outer cylinder body of the third processing cylinder 5.

[0108] In some embodiments, the first processing cylinder 2 and the second processing cylinder 3 are rigidly or rigidly connected.

[0109] Optionally, such as Figure 3 and Figure 4 As shown, the rigid or hard connection between the first processing cylinder 2 and the second processing cylinder 3 improves the connection stability and firmness of the first processing cylinder 2 and the second processing cylinder 3, and ensures that the overall shock absorption effect of the garment processing equipment can be achieved by adjusting the rotation direction of the first processing cylinder 2 and / or the second processing cylinder 3, thereby improving the user experience.

[0110] In some embodiments, the garment processing device further includes a fixing frame 6, which is connected between the first processing cylinder 2 and the second processing cylinder 3.

[0111] Optionally, such as Figure 3 As shown, the fixing frame 6 is connected to the first processing cylinder 2 and the second processing cylinder 3, which can improve the stability of the first processing cylinder 2 and the second processing cylinder 3 during rotation. In other words, the fixing frame 6 can constrain the position of the first processing cylinder 2 and the second processing cylinder 3, which helps to reduce the swaying amplitude of the first processing cylinder 2 and the second processing cylinder 3 during rotation, thereby reducing the noise generated by the clothing processing equipment during operation.

[0112] Optionally, the fixing frame 6 can be a grid-like rib structure, with the left side of the fixing frame 6 connected to the outer wall of the first processing cylinder 2 and the right side of the fixing frame 6 connected to the outer wall of the second processing cylinder 3. This can further improve the stability of the first processing cylinder 2 and the second processing cylinder 3 during operation.

[0113] In some embodiments, the highest point of the fixing frame 6 is lower than the highest point of the first processing cylinder 2 and the highest point of the second processing cylinder 3, and the lowest point of the fixing frame 6 is higher than the lowest point of the first processing cylinder 2 and the lowest point of the second processing cylinder 3.

[0114] Optionally, such as Figure 3 As shown, the highest point of the fixing frame 6 is lower than the highest point of the first processing cylinder 2 and the highest point of the second processing cylinder 3. It can be understood that the top surface of the fixing frame 6 is lower than the top surface of the first processing cylinder 2 and the top surface of the second processing cylinder 3. Therefore, the upper surface of the fixing frame 6, the outer wall surface of the first processing cylinder 2, and the outer wall surface of the second processing cylinder 3 together form a component receiving space. This component receiving space can be used to place components such as the drying module, the feeding module, the electrical control module, and the sterilization module, thereby making the overall structure of the garment processing equipment more compact and improving space utilization.

[0115] Optionally, such as Figure 3 As shown, the lowest point of the mounting bracket 6 is higher than the lowest points of the first processing cylinder 2 and the second processing cylinder 3. It can be understood that the bottom surface of the mounting bracket 6 is slightly higher than the bottom surfaces of the first processing cylinder 2 and the second processing cylinder 3. Thus, the bottom surface of the mounting bracket 6, the outer wall surface of the first processing cylinder 2, and the outer wall surface of the second processing cylinder 3 together form a clearance space to avoid interference with the third processing cylinder 5 during assembly.

[0116] In some embodiments, such as Figure 4As shown, the housing 1 has a suspension beam 7 located above the first processing cylinder 2 and the second processing cylinder 3, and the suspension beam 7 is connected to the first processing cylinder 2 and the second processing cylinder 3. The suspension beam 7 extends in the left-right direction. The top surface of the first processing cylinder 2 is connected to the left side of the suspension beam 7, and the top surface of the second processing cylinder 3 is connected to the right side of the suspension beam 7. The connection between the suspension beam 7 and the first processing cylinder 2 and the second processing cylinder 3 facilitates the fixing of the first processing cylinder 2 and the second processing cylinder 3 inside the housing 1, further improving the connection strength between the first processing cylinder 2 and the second processing cylinder 3.

[0117] In some embodiments, such as Figures 2-3 As shown, the first processing cylinder 2, the second processing cylinder 3 and the third processing cylinder 5 all have a retrieval port 4, which faces the front of the housing 1.

[0118] In the clothing processing device of this embodiment, the inlets 4 of the first processing drum 2, the second processing drum 3, and the third processing drum 5 are all arranged facing forward. The first processing drum 2, the second processing drum 3, and the third processing drum 5 can all be drum-type processing drums, which makes it convenient for users to pick up and put in clothes from the front, while improving the washing and care effect of clothes and improving energy efficiency.

[0119] Optionally, the garment processing equipment can be a drum washing machine, a drum dryer, or a drum washer-dryer combo. Accordingly, any one of the first processing drum 2, the second processing drum 3, and the third processing drum 5 can be used to dry or wash clothes, or any one of the first processing drum 2, the second processing drum 3, and the third processing drum 5 can both dry and wash clothes.
