Description

Technical Field

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

[0002] In related technologies, clothing processing equipment has limited functionality and suffers from low space utilization in its overall structural layout. Utility Model Content

[0003] The purpose of this disclosure is to provide a garment processing device that integrates multiple functions without encroaching on the effective washing volume, thereby improving space utilization and at least partially solving the aforementioned technical problems.

[0004] To achieve the above objectives, a first aspect of this disclosure provides a garment processing apparatus, comprising: First cylinder; The second cylinder; and An ultrasonic cleaning device is located between the first cylinder and the second cylinder, and the ultrasonic cleaning device is used to clean the items to be cleaned.

[0005] By optimizing the layout, the space is used efficiently and the space utilization rate is improved. Without affecting the effective washing capacity of the first and second drums, the functions are compactly integrated, the washing functions are diversified, the user experience is improved, and a variety of cleaning services are provided more conveniently.

[0006] In some possible implementations, the first drum is located above the second drum; wherein the ultrasonic washing device is located below the first drum; and / or, the ultrasonic washing device is located below the rotation axis of the first drum. Through optimized layout design, the space between the first and second drums is rationally utilized, improving the overall integration of the equipment. Furthermore, the partitioned functional layout ensures that the first, second, and third drums are separated and do not interfere with each other, allowing for simultaneous or individual operation, thus enhancing reliability and convenience. The ultrasonic washing device being located below the first drum; and / or below the rotation axis of the first drum, fully utilizes the space below the first drum or below its rotation axis, improving space utilization.

[0007] In some possible implementations, the ultrasonic washing device is located above the second drum; and / or, the ultrasonic washing device is located above the rotation axis of the second drum. Through optimized layout design, a functional layout with upper and lower partitions is formed. The ultrasonic washing device and the second drum are separated and do not interfere with each other, allowing them to operate simultaneously or independently. Furthermore, this layout reduces noise and vibration transmission, preventing vibrations generated by the high-speed rotation of the second drum during the washing process from interfering with the ultrasonic washing device. In addition, the space above the second drum or above its rotation axis can be fully utilized, improving space utilization.

[0008] In some possible implementations, the outer diameter of the first drum is smaller than the outer diameter of the second drum. This dimensional difference design allows for adjustment of the effective washing volume of the first and second drums, enabling different drums to be specifically designed for different items to be washed, thus achieving functional differentiation and improving the user experience.

[0009] In some possible implementations, there are multiple first drums, which are arranged at intervals along the width of the garment processing equipment. This allows for the efficient arrangement of multiple first drums within a limited space, improving space utilization. It also facilitates the functional differentiation of different first drums based on washing type and enables users to process multiple batches of items (e.g., clothes) simultaneously, increasing washing capacity and efficiency.

[0010] In some possible implementations, there are two first drums, with the two rotation axes of the two first drums located on opposite sides of the vertical plane containing the rotation axis of the second drum. The ultrasonic washing device is located below at least one of the first drums. Through optimized layout design, a compact three-dimensional arrangement is achieved, making the overall center of gravity more central, reducing the impact of lateral torque during operation, and improving operational stability. Furthermore, the vertical arrangement optimizes the pipeline layout between the first and second drums, reducing structural interference and improving space utilization and reliability.

[0011] In some possible implementations, the garment processing equipment includes a mounting plate at least partially located between the first and second drums, to which the ultrasonic washing device is connected. The mounting plate provides mounting conditions for the ultrasonic washing device, allowing it to operate independently of the first and second drums, avoiding mutual interference, and improving structural stability and safety.

[0012] In some possible implementations, the garment processing equipment includes a frame, and the mounting plate includes a first plate and a second plate. The first plate is located on the front side of the frame along the front-rear direction of the garment processing equipment, and the second plate is located on one or the other side of the frame along the width direction of the garment processing equipment. The ultrasonic washing device is connected to the first plate and the second plate respectively. Through the above structural design, the installation position of the ultrasonic washing device can be flexibly adjusted, and it can also be flexibly expanded according to capacity and functional requirements. For example, two ultrasonic washing devices can be set to further improve the functionality of the whole machine and increase the layout flexibility and reliability of the whole machine.

[0013] In some possible implementations, the ultrasonic cleaning device includes a housing, a pull-out component, and an ultrasonic transducer connected to the housing. The housing has a receiving cavity and a first opening communicating with the receiving cavity. The receiving cavity is capable of containing cleaning fluid. The pull-out component is movably inserted into the receiving cavity through the first opening, and the pull-out component is used to carry the item to be cleaned. Through the above structural design, the drawer-type design of the ultrasonic cleaning device facilitates the storage and retrieval of items to be cleaned (such as jewelry, eyeglasses, etc.), allowing the item to be cleaned to be directly carried by the pull-out component and act with the cleaning fluid within the receiving cavity, achieving independent and precise ultrasonic cleaning, and offering greater convenience and reliability.

[0014] In some possible implementations, the garment handling device includes a front panel having a second opening through which the pull-out component moves, such that the pull-out component, in the open position, is at least partially located outside the front panel. This facilitates user access to garments to be washed and allows for clear observation of the location of the ultrasonic washing device, enhancing ease of use.

[0015] In some possible implementations, the housing has an inlet and an outlet communicating with the receiving cavity, the outlet being connected to the second cylinder, and / or, the outlet being connected to a drainage assembly on the second cylinder. In this way, the ultrasonic washing device and the second cylinder are both independent and synergistic, improving overall integrity. The waste liquid from the receiving cavity is guided into the second cylinder and discharged through a unified drainage path, reducing the risk of leakage. Gravity-assisted drainage reduces residual liquid retention, while also simplifying piping and valve configuration for centralized maintenance and cleaning.

[0016] In some possible implementations, the water outlet is constructed as a siphon structure with a siphon channel. One end of the siphon channel communicates with the receiving cavity, and the other end serves as a drain outlet. By setting up a siphon structure, the unidirectional discharge and evacuation or near-evacuation of the waste liquid in the receiving cavity is automatically triggered and completed using the liquid level difference. This reduces backflow, improves the thoroughness and reliability of drainage, reduces the need for additional drainage structures such as pumps and water valves, lightens the overall weight of the machine, reduces the space occupied by the ultrasonic washing device, and facilitates integrated layout.

[0017] In some possible implementations, the height of the drain outlet is lower than or equal to the lowest point of the liquid in the receiving cavity. This ensures the proper functioning of the siphon process and achieves stable and continuous discharge of waste liquid.

[0018] In some possible implementations, the siphon channel includes a water intake section and a drainage section. The bottom end of the water intake section communicates with the receiving cavity, and the top end of the water intake section communicates with the top end of the drainage section. The bottom end of the drainage section is provided with a drain outlet. This structural design creates a continuous flow path with a clear drop between the water intake section and the drainage section, allowing the liquid in the receiving cavity to be smoothly guided to the water intake section and discharged through the drain outlet at the bottom of the drainage section. This avoids liquid backflow and air pressure blockage, improving the smoothness and reliability of drainage.

[0019] In some possible implementations, the siphon structure includes a partition and a cover; wherein the partition is connected to the inner wall of the receiving cavity and forms at least a portion of the drainage section between the partition and the inner wall of the receiving cavity, the cover is disposed on the partition, and the water intake section is formed between the outer wall of the partition and the inner wall of the cover. Through the combined design of the cover and the partition, the gap between them forms the water intake section, and the gap between the partition and the receiving cavity forms the drainage section. This allows for control of the length of the water intake section by adjusting the cover, ensuring a height difference between the drain outlet of the drainage section and the inlet of the water intake section, thus ensuring the normal operation of the siphon process. Furthermore, the split-type structure design facilitates easy assembly and disassembly, enabling stable communication between the water intake section and the drainage section. Alternatively, the partition itself forms at least a portion of the drainage section, the cover is disposed on the partition, and the water intake section is formed between the outer wall of the partition and the inner wall of the cover. By optimizing the structure of the partition, the placement of the partition can be flexibly adjusted. For example, it can be placed in any suitable position within the receiving cavity without needing to be connected to the inner wall of the receiving cavity. Siphon drainage can be achieved simply by the cooperation between the partition and the cover, making it more flexible in use.

[0020] In some possible implementations, one of the outer sidewall of the partition and the inner sidewall of the cover is provided with a guide rail, and the other with a guide groove. The guide rail and the guide groove are slidably engaged to guide the cover onto the partition, thus facilitating the assembly and disassembly of the partition and the cover, reducing frictional loss, and making the assembly and disassembly process faster and smoother. And / or, a support is provided at the bottom end of the outer sidewall of the partition and / or on the bottom surface of the receiving cavity, and the cover is supported on the support, so that a gap is formed between the cover and the bottom surface of the receiving cavity, communicating with the siphon channel. The support of the cover ensures that a gap exists between the installed partition and the bottom wall of the receiving cavity, and the inlet of the water intake section communicates with the receiving cavity, ensuring the continuous and stable operation of the siphon effect.

[0021] In some possible implementations, the siphon structure is located at the end of the housing opposite to the first opening. Through a rationally optimized layout design, the siphon structure is positioned away from the first opening, i.e., away from the user's access area, to reduce accidental contact and prevent damage to the siphon structure due to human error. This also avoids interference with the access to the items to be washed, resulting in greater reliability and stability in use.

[0022] In some possible embodiments, the ultrasonic washing device further includes a water receiving tank, with the drain outlet of the water outlet located above or within the water receiving tank. The water receiving tank has a drain port connected to the second cylinder or the drainage assembly. Through this structural design, the water receiving tank can act as a buffer and collection point to receive discharged waste liquid, intercepting impurities in the waste liquid and preventing it from directly entering the machine's drainage system, thus reducing the risk of blockage. Simultaneously, the water receiving tank can also temporarily store excess waste liquid, preventing blockage or backflow caused by excessive instantaneous flow. Furthermore, the water receiving tank allows the siphon process to proceed normally and prevents waste liquid backflow.

[0023] In some possible implementations, the drainage assembly includes a first pipe, a drain pump, and a second pipe connected in sequence. The end of the first pipe opposite to the drain pump is connected to a second cylinder. The second pipe connects the drain pump to the outside of the garment processing equipment. The drain outlet is connected to the first pipe, the second pipe, or the drain pump via a water outlet pipe. This allows the cleaning solution in the receiving tank to be discharged through the first pipe, the second pipe, or the drain pump connected to the water outlet pipe, providing flexible options and improving the integration of the garment processing equipment.

[0024] In some possible implementations, the drainage assembly includes a first pipe, a drain pump, and a second pipe connected in sequence. The end of the first pipe opposite to the drain pump is connected to a second cylinder. The second pipe connects the drain pump to the outside of the garment processing device. The drain outlet is connected to the first pipe, the second pipe, or the drain pump via a water outlet pipe. Thus, in embodiments that do not employ a siphon structure and a water receiving tank, the cleaning liquid within the receiving cavity can be discharged through the water outlet, the water outlet pipe, the first pipe, the second pipe, or the drain pump, improving the integration of the garment processing device.

[0025] In some possible implementations, the pull-out component has a support portion for carrying the item to be washed, the support portion having multiple through holes through which the cleaning fluid flows. The support portion provides storage space for the item to be washed, and the porous design allows the cleaning fluid to completely submerge the item, improving the thoroughness of the cleaning and enhancing the cleaning effect.

[0026] In some possible implementations, the support portion includes a mesh structure with through-holes in the mesh. This mesh design allows the cleaning fluid to completely cover the item to be cleaned, thereby improving the thoroughness of the cleaning process and reducing overall weight.

[0027] In some possible implementations, the pull-out component includes a cover, with the support portion connected to the side of the cover facing the first opening. The cover is configured to operably seal the first opening. The garment handling device includes a front panel having a second opening through which the pull-out component moves, and the cover is capable of covering the second opening. The cover forms a reliable seal to the second opening when the pull-out component moves into the receiving cavity, effectively preventing external contaminants from entering the receiving cavity and avoiding leakage of cleaning fluid or water.

[0028] In some possible implementations, one of the cover and the housing is provided with a sealing portion, which is capable of sealingly fitting against the other of the cover and the housing, and the sealing portion is arranged around the first opening; alternatively, both the cover and the housing are provided with sealing portions, and the sealing portions on the cover and the housing are sealed together, with the sealing portions arranged around the first opening. By providing sealing portions, a stable and reliable liquid-tight and air-tight barrier can be formed between the cover and the housing, thereby suppressing cleaning fluid leakage, odor escape, etc., reducing cleaning fluid splashing and noise pollution caused by the operation of the ultrasonic cleaning device, and improving reliability and safety in use.

[0029] In some possible implementations, one of the pull-out component and the housing is provided with a guide portion, and the other is provided with a guide mating portion. The guide portion and the guide mating portion slide together to guide the pull-out component to be movably inserted into the housing. By providing the guide portion and the guide mating portion to guide the pull-out component, directional guidance and effective support can be provided during the reciprocating pull-out sliding process of storing and retrieving the item to be washed, reducing jamming and wear, and improving load-bearing stability and smoothness.

[0030] In some possible implementations, the ultrasonic transducer is disposed inside the housing. This allows the housing to protect the ultrasonic transducer, extend its service life, improve the overall integration and safety of the machine, and optimize the sound wave transmission path, thereby enhancing the cleaning effect.

[0031] In some possible implementations, the ultrasonic transducer is located outside the housing to optimize the wiring layout, reduce wiring complexity, and facilitate maintenance and replacement, while still achieving effective cleaning of the items to be washed.

[0032] In some possible implementations, the portion of the housing that fits into the ultrasonic transducer is a metal part. The ultrasonic transducer is connected to the side of the metal part facing away from the receiving cavity, and the inner surface of the metal part facing the receiving cavity is used to contact the cleaning fluid. The metal part can provide good transmission conditions for the vibrations released by the ultrasonic transducer, and the direct contact between the inner surface of the metal part and the cleaning fluid can improve cavitation efficiency and cleaning intensity.

[0033] In some possible implementations, the metal part has a mounting groove for mounting the ultrasonic transducer. The mounting groove provides mounting space for the ultrasonic transducer, ensures a flat and secure fit, reduces the occupancy of external space, increases the effective contact area, and thus improves the cleaning effect.

[0034] In some possible implementations, the housing includes a housing portion connected to the metal portion; wherein the metal portion and the housing portion are injection molded integrally. This integrated design reduces the number of unnecessary parts and assembly gaps, effectively improving structural rigidity and vibration resistance.

[0035] In some possible implementations, the garment processing device includes a water inlet pipe communicating with the receiving cavity, and an electrically controlled valve is installed on the water inlet pipe; and / or, a sensor for detecting the liquid level in the receiving cavity is installed on the housing. Thus, by adjusting the opening degree and opening time of the electrically controlled valve, the amount of water entering the receiving cavity can be controlled, preventing excessive water volume from causing the cleaning solution to overflow and be wasted; the water level information in the receiving cavity can be obtained through the sensor's detection data to further control the opening and closing of the electrically controlled valve.

[0036] In some embodiments, the minimum distance between the ultrasonic washing device and the second drum is greater than or equal to 15 mm; and / or, the minimum distance between the ultrasonic washing device and the first drum is greater than or equal to 20 mm. This avoids the ultrasonic washing device being too close to the first and second drums, which could affect the arrangement and use of the drums.

[0037] By employing the aforementioned technical solution, the ultrasonic washing device is positioned between the first and second drums, achieving efficient space utilization and improving space efficiency. Without affecting the effective washing volume of the first and second drums, it achieves compact functional integration, optimizes the spatial layout, and clearly separates the functional areas for easy user operation. Furthermore, the sandwich effect formed by the first and second drums effectively suppresses noise pollution generated by the ultrasonic washing device. Therefore, the clothing processing equipment provided by this disclosure offers diversified washing functions, enhances the user experience, and provides greater convenience.

Detailed Implementation

[0041] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.

[0042] In this disclosure, unless otherwise stated, directional terms such as "up," "down," "front," "back," "left," and "right" are used based on the definition of the garment handling equipment, which can be found in the following references. Figure 1 and Figure 2 The X, Y, and Z directions in the text refer to the width (or left-right direction) of the garment processing equipment, the height (or up-down direction), and the thickness (or front-back direction). The up-down direction can be referenced to the gravity direction of the garment processing equipment. In the front-back direction, "front" can be understood as the side of the garment processing equipment facing the user, and "back" as the side away from the user. The garment processing equipment's gate is typically located on the front side. "Inner" and "outer" refer to the inner and outer contours of each component. Furthermore, the terms "first" and "second" used in this disclosure are for distinguishing one element from another and do not have sequential or importance implications. Additionally, when the following description relates to the accompanying drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0043] according to Figures 1 to 16 As shown, in a first aspect, this disclosure provides a garment processing device that may include a first tub 1, a second tub 2, and an ultrasonic washing device 3 located between the first tub 1 and the second tub 2, the ultrasonic washing device 3 being used to clean garments to be washed.

[0044] Through the above technical solution, the ultrasonic washing device 3 is arranged between the first drum 1 and the second drum 2, which realizes efficient use of space and improves space utilization. Without affecting the effective washing volume of the first drum 1 and the second drum 2, the functions are compactly integrated, the washing functions are diversified, the user experience is improved, and it is more convenient. The space layout is optimized, and the functional areas are clearly separated for easy operation. In addition, the sandwich effect formed by the first drum 1 and the second drum 2 can effectively suppress the noise pollution generated by the ultrasonic washing device 3.

[0045] The items to be washed may include, for example, metal or non-metal products such as jewelry, eyeglasses, and watches, as well as flexible woven fabrics such as baby clothing and socks. This disclosure is not limited thereto.

[0046] In some feasible ways, for example, refer to Figure 1 and Figure 2 As shown, the first cylinder 1 can be located above the second cylinder 2. Through optimized layout design, the space between the first cylinder 1 and the second cylinder 2 is rationally utilized, improving the overall integration of the equipment. In addition, through the partitioned functional layout, the first cylinder 1, the second cylinder 2 and the ultrasonic washing device 3 are separated from each other and do not interfere with each other, and can operate simultaneously or individually, making them more reliable and convenient to use.

[0047] In some feasible embodiments, the ultrasonic washing device 3 may be located below the first cylinder 1, and / or the ultrasonic washing device 3 may be located below the rotation axis of the first cylinder 1 to make full use of the space below the first cylinder 1 or below the rotation axis.

[0048] In some feasible embodiments, for example, the ultrasonic washing device 3 can be located above the second drum 2. Through optimized layout design, a functional layout with upper and lower partitions is formed, in which the ultrasonic washing device 3 and the second drum 2 are separated from each other and do not interfere with each other. They can operate simultaneously or independently. Furthermore, this layout can reduce noise and vibration transmission and prevent the vibration generated by the high-speed rotation of the second drum 2 during the washing process from interfering with the ultrasonic washing device 3.

[0049] In some feasible ways, refer to Figure 1 As shown, the ultrasonic washing device 3 can be located above the rotation axis of the second drum 2. This further avoids the impact of the high-speed rotation / oscillation of the second drum 2 during the washing process on the ultrasonic washing device 3, effectively preventing the transmission of collisions and vibrations, and thus improving reliability and safety in use.

[0050] It should be noted that the ultrasonic washing device 3 can be arranged at intervals with the first cylinder 1 and the second cylinder 2. For example, the minimum distance between the ultrasonic washing device 3 and the second cylinder 2 can be greater than or equal to 15mm, and the minimum distance between the ultrasonic washing device 3 and the first cylinder 1 can be greater than or equal to 20mm. In this way, it can avoid the ultrasonic washing device 3 affecting the arrangement and use of the cylinders due to being too close to the first cylinder 1 and the second cylinder 2, and it can also avoid the ultrasonic washing device 3 causing a waste of space due to being too far away from the cylinders.

[0051] In some feasible embodiments, the minimum distance between the ultrasonic washing device 3 and the second cylinder 2 can be 15 mm, 16 mm, or 17 mm, and the minimum distance between the ultrasonic washing device 3 and the first cylinder 1 can be 20 mm, 21 mm, or 22 mm. This disclosure is not limited thereto.

[0052] In some feasible ways, for example, refer to Figures 1 to 3 As shown, the outer diameter of the first drum 1 can be smaller than the outer diameter of the second drum 2. Through the size difference design, the effective washing volume of the first drum 1 and the second drum 2 can be adjusted, thereby enabling different drums to be specifically designed for different items to be washed, achieving functional differentiation and improving the user experience.

[0053] For example, there can be multiple first drums 1, which are arranged at intervals along the width of the garment processing equipment. In this way, multiple first drums 1 are arranged in a reasonable manner within a limited space, which improves the space utilization rate, facilitates the functional differentiation of different washing types for different first drums 1, and enables users to process multiple batches of items to be washed (such as clothes) at the same time, thereby improving washing capacity and efficiency and meeting users' needs for multifunctional and high-efficiency garment processing equipment.

[0054] In some feasible ways, for example, refer to Figure 1 and Figure 2 As shown, there can be two first drum bodies 1. The two rotation axes of the two first drum bodies 1 are located on both sides of the vertical plane where the rotation axis of the second drum body 2 is located (e.g., the upper left and upper right). An ultrasonic washing device 3 is provided below at least one first drum body 1. Through the optimized layout design, a three-dimensional compact layout is formed, making the center of gravity of the whole machine more central, reducing the impact of lateral torque during operation, and improving the stability of operation. In addition, by arranging them vertically, the pipeline arrangement between the first drum body 1 and the second drum body 2 can be optimized, reducing structural interference, improving space utilization and reliability of use.

[0055] In some feasible ways, for example, refer to Figure 2 As shown, the garment processing equipment may include a mounting plate 5 located at least partially between the first drum 1 and the second drum 2, and an ultrasonic washing device 3 is connected to the mounting plate 5. The mounting plate 5 provides installation conditions for the ultrasonic washing device 3, allowing the ultrasonic washing device 3 to be independent of the first drum 1 and the second drum 2, avoiding mutual interference, improving the stability and safety of the structure, and facilitating subsequent disassembly and maintenance.

[0056] In some feasible ways, for example, refer to Figure 2 As shown, the garment processing equipment may include a frame 4, and the mounting plate 5 may include a first plate 51 and a second plate 52. The first plate 51 is located on the front side of the frame 4 along the front-rear direction of the garment processing equipment, and the second plate 52 is located on the left or right side of the frame 4 along the left-right direction of the garment processing equipment. The ultrasonic washing device 3 is connected to the first plate 51 and the second plate 52 respectively. Through the above structural design, the installation position of the ultrasonic washing device 3 can be flexibly adjusted. For example, the retrieval port of the garment to be washed of the ultrasonic washing device 3 can be located on the front side, or on the left or right side. In addition, it can be flexibly added according to capacity and functional requirements. For example, two ultrasonic washing devices 3 can be set, located on the left and right sides of the garment processing equipment along the width direction respectively, to further improve the functionality of the whole machine and increase the layout flexibility and reliability of the whole machine.

[0057] In some feasible ways, for example, refer to Figures 4 to 16 As shown, the ultrasonic cleaning device 3 may include a housing 30, a pull-out member 31, and an ultrasonic transducer 32 connected to the housing 30. The housing 30 has a receiving cavity 33 and a first opening 34 communicating with the receiving cavity 33. The receiving cavity 33 can hold cleaning fluid. The pull-out member 31 is movably inserted into the receiving cavity 33 through the first opening 34 and is used to carry the items to be cleaned. Through the above structural design, the drawer-type design of the ultrasonic cleaning device 3 facilitates the storage and retrieval of items to be cleaned (such as jewelry, glasses, etc.), allowing the items to be cleaned to be directly carried by the pull-out member 31 and act with the cleaning fluid in the receiving cavity 33, achieving independent and precise ultrasonic cleaning, and providing greater convenience and reliability.

[0058] The cleaning solution can be adapted to meet specific needs. For example, when cleaning jewelry, eyeglasses, or similar items, an ultrasonic cleaner can be used; when cleaning clothing, laundry detergent can be used. Of course, the cleaning solution can also be water or a water mixture with added detergent. This disclosure does not impose any specific limitations in this regard.

[0059] For example, the ultrasonic transducer 32 may include a housing and a piezoelectric material (e.g., ceramic material), electrodes, a vibrator, an acoustic matching layer, and cables and connectors disposed within the housing. The piezoelectric material is used to convert electrical energy into ultrasonic waves or to convert ultrasonic waves into electrical signals. The electrodes are connected to an external circuit to realize the input and output of electrical signals. The vibrator is connected to the piezoelectric material to enhance the radiation efficiency of the sound waves. The acoustic matching layer is located between the piezoelectric material and the medium to improve the coupling efficiency of the sound waves and reduce reflections. The cables and connectors enable the ultrasonic transducer 32 to connect to external devices, ensuring signal transmission and normal operation of the transducer.

[0060] For details regarding the specific structure and working principle of the ultrasonic transducer 32, those skilled in the art can refer to existing technologies and literature; this disclosure will not elaborate further.

[0061] The ultrasonic transducer 32 can be installed inside the housing 30, which protects the ultrasonic transducer 32, extends its service life, improves the overall integration and safety of the machine, and optimizes the sound wave transmission path to improve the cleaning effect. Alternatively, the ultrasonic transducer 32 can be installed outside the housing 30 to optimize the circuit layout, reduce the complexity of the circuit, and facilitate maintenance and replacement, while still achieving effective cleaning of the items to be washed.

[0062] In some feasible embodiments, the garment handling device may include a front panel (not shown) having a second opening (not shown) through which a pull-out member 31 moves, such that the pull-out member 31 is at least partially located outside the front panel in the open position. This facilitates user access to the garments to be washed and allows for clear observation of the location of the ultrasonic washing device 3, thus enhancing ease of use.

[0063] In some feasible ways, for example, refer to Figures 4 to 11 As shown, the housing 30 has a water inlet 303 and a water outlet 304 communicating with the receiving cavity 33, and the water outlet 304 is connected to the second cylinder 2. In this way, the ultrasonic washing device 3 and the second cylinder 2 are both independent and work together, improving the overall integrity. The waste liquid that has been cleaned in the receiving cavity 33 is introduced into the second cylinder 2 and discharged through a unified drainage path, which can reduce the risk of leakage. Gravity-assisted drainage can reduce residual liquid retention, and at the same time, it can simplify the configuration of pipelines and valves for centralized maintenance and cleaning.

[0064] It is understood that the water outlet 304 can also be connected to the drainage component 7 on the second cylinder 2, or the water outlet 304 can also be connected to the interior of the second cylinder 2 and the drainage component 7 respectively, which can also achieve effective discharge of waste liquid and reduce the risk of leakage and retention. This disclosure is not limited thereto.

[0065] In some feasible ways, for example, refer to Figures 7 to 16 As shown, the water outlet 304 can also be configured as a siphon structure 8, which has a siphon channel 81. One end of the siphon channel 81 is connected to the receiving cavity 33, and the other end of the siphon channel 81 is a drain outlet 811. By setting the siphon structure 8, the unidirectional discharge and evacuation of waste liquid in the receiving cavity 33 is automatically triggered by the liquid level difference, reducing backflow, improving the thoroughness and reliability of drainage, reducing additional drainage structures such as pumps and water valves, reducing the overall weight of the machine, reducing the space occupied by the ultrasonic washing device 3, and facilitating integrated layout.

[0066] The height of the drain outlet 811 can be lower than or equal to the lowest point of the liquid in the receiving cavity 33. This ensures the normal operation of the siphon process. For example, the lowest point of the liquid can be the lowest point of the bottom wall of the receiving cavity 33, that is, the height of the drain outlet 811 can be lower than or at the same level as the lowest point of the bottom wall of the receiving cavity 33. This disclosure is not limited thereto.

[0067] In some feasible ways, for example, refer to Figure 13As shown, the siphon channel 81 may include a water intake section 812 and a drainage section 813. The bottom end of the water intake section 812 is connected to the receiving cavity 33, and the top end of the water intake section 812 is connected to the top end of the drainage section 813. A drain outlet 811 is provided at the bottom end of the drainage section 813. Through the above structural design, a continuous flow path with a clear drop is formed between the water intake section 812 and the drainage section 813, so that the liquid in the receiving cavity 33 can be smoothly guided to the water intake section 812 and discharged through the drain outlet 811 at the bottom end of the drainage section 813. This effectively avoids liquid backflow and air pressure blockage, and improves the smoothness and reliability of drainage.

[0068] For example, the siphon structure 8 may include a partition 83 and a cover 82. The partition 83 is connected to the inner wall of the receiving cavity 33 and forms at least a partial drainage section 813 between the partition 83 and the inner wall of the receiving cavity 33. The cover 82 covers the partition 83, and a water intake section 812 is formed between the outer wall of the partition 83 and the inner wall of the cover 82. Through the combined design of the cover 82 and the partition 83, the gap between the two forms the water intake section 812, and the gap between the partition 83 and the receiving cavity 33 forms the drainage section 813. This allows the length of the water intake section 812 to be controlled by adjusting the cover 82, ensuring a height difference between the drain outlet 811 of the drainage section 813 and the inlet 810 of the water intake section 812, thus ensuring the normal operation of the siphon process. Furthermore, the split structure design makes it easy to assemble and disassemble, enabling stable communication between the water intake section 812 and the drainage section 813.

[0069] Furthermore, in another embodiment not shown, the partition 83 itself can form at least a partial drainage section 813, with the cover 82 covering the partition 83, and a water-guiding section 812 formed between the outer wall of the partition 83 and the inner wall of the cover 82. Through optimized structural design of the partition 83, its arrangement can be flexibly adjusted. For example, it can be placed at any suitable position within the receiving cavity 33 without needing to connect to the inner wall of the receiving cavity 33. Siphon drainage can be achieved solely through the cooperation of the partition 83 and the cover 82, providing greater flexibility in use.

[0070] In some feasible embodiments, the cover portion 82 may be integrally constructed with the housing 30, for example, it may be integrally constructed with the lower housing 302 (described below) to reduce assembly difficulty and improve assembly efficiency.

[0071] In some possible implementations, for example, refer to Figure 15 and Figure 16As shown, one of the outer side wall of the partition 83 and the inner side wall of the cover 82 can be provided with a guide rail 831, and the other can be provided with a guide groove. The guide rail 831 and the guide groove slide together to guide the cover 82 onto the partition 83. This facilitates the assembly and disassembly of the partition 83 and the cover 82, reduces frictional wear, and makes the assembly and disassembly process faster and smoother. Figure 15 In the exemplary embodiment shown, a guide rail 831 extending in the vertical direction is provided on the partition 83, and a corresponding guide groove is provided on the cover 82. The number of guide rails 831 can be multiple and arranged side by side, which facilitates guiding the cover to connect to or insert into the partition, and can also restrict the cover from disengaging from the partition 83 in other directions that are at an angle to the insertion direction.

[0072] In addition, the cover portion 82 can also be bonded to the housing or fastened together, but this disclosure is not limited thereto.

[0073] Optionally, refer to Figure 8 As shown, a support portion 306 may be provided at the bottom end of the outer wall of the partition portion 83 and / or on the bottom surface of the receiving cavity 33. The cover portion 82 is supported on the support portion 306, so that a gap is formed between the cover portion 82 and the bottom surface of the receiving cavity 33, communicating with the siphon channel 81. Exemplarily, the support portion 306 may protrude from the bottom wall of the receiving cavity 33, so that there is a gap between the partition portion 83 and the bottom wall of the receiving cavity 33 after installation, and the inlet 810 of the water inlet section 812 communicates with the receiving cavity 33. In this way, when drainage is required, the user can operate the water inlet distribution assembly 6 to inject water into the receiving cavity 33 until the water gradually submerges the top of the water inlet section 812. At this time, since the height of the inlet 810 of the water inlet section 812 is higher than the height of the drain outlet 811 of the drainage section 813, the pressure difference can push the liquid over the top of the water inlet section 812, enter the drainage section 813, and discharge the liquid through the drain outlet 811. In this embodiment, the partition 83 can be detachably connected to the housing 30. For example, the partition 83 can be connected to the housing 30 by means of adhesive bonding or fastener connection, depending on the positioning of the support 306. Alternatively, the partition 83 can be integrally constructed with the housing, but this disclosure is not limited thereto.

[0074] The support portion 306 may include multiple positioning blocks, each with a slot. The bottom end of the cover portion can engage with the slot to enhance the connection stability between the two. This disclosure is not limited thereto.

[0075] Understandably, siphoning is a fluid dynamics phenomenon that allows liquid to be drawn without a pump. For example, after liquid at a higher position fills an inverted U-shaped tubular structure (called a siphon tube), the drain outlet 811 is located at a lower position. The pressure difference between the two ends of the tube can push the liquid over the highest point of the siphon channel 81 and discharge it into the drain outlet 811. Furthermore, the height of the bend in the siphon channel 81 (i.e., the connection point between the inlet section 812 and the outlet section 813) also determines the maximum water level that the receiving cavity 33 can hold. If the height of the bend in the siphon channel 81 is low, it means that the maximum water level that the receiving cavity 33 can hold is also low. For example, during the washing process of the ultrasonic washing device 3, the liquid level of the ultrasonic washing device 3 can be controlled by controlling the opening time of the electrically controlled valve on the water inlet pipe 62 connected to the receiving cavity 33. For example, when the ultrasonic washing device 3 needs to be used for cleaning, the electrically controlled valve on the water inlet pipe 62 can be opened and closed after a first preset time period, so that the liquid level in the receiving cavity 33 is lower than any position of the top of the water inlet section 812. For example, the liquid level can be the position that submerges the item to be washed and is lower than the top of the water inlet section 812. This position can be preset as the cleaning liquid level for cleaning the item to be washed. At this time, the receiving cavity 33 will not trigger siphon drainage. After cleaning, the liquid level in the receiving cavity 33 can be increased by controlling the electrically controlled valve. A fixed amount of water or cleaning fluid is used to raise the liquid level in the receiving cavity 33. As the liquid level continues to rise, the liquid entering the water inlet section 812 gradually approaches the top of the water inlet section 812. Once the water inlet section 812 is filled with liquid, a siphon effect is triggered. Through the pressure difference, the liquid in the water inlet section 812 enters the drain section 813 and is discharged through the drain outlet 811 of the drain section 813. During this process, the liquid in the receiving cavity 33 will be continuously drawn into the water inlet section 812 through the inlet 810 until the liquid in the receiving cavity 33 is completely discharged or the siphon effect ends. By setting the opening time of the electrically controlled valve, it can be ensured that the liquid rises from the cleaning liquid level to the top of the water inlet section 812 and enters the drain section 813 and triggers the siphon effect. In some embodiments of the ultrasonic cleaning device 3 described in this application, it is not necessary to install a water pump or control valve in the drainage method of the receiving cavity 33. Instead, the drainage process is indirectly controlled by an electrically controlled valve on the water inlet pipe 62 in the water supply control mode. This makes the ultrasonic cleaning device 3 smaller in size and occupies less space, which is convenient for the use and arrangement of the ultrasonic cleaning device 3. Furthermore, the smaller size of the ultrasonic cleaning device 3 also makes it easier to integrate with other cleaning devices.

[0076] In some feasible ways, for example, refer to Figures 4 to 13As shown, the ultrasonic washing device 3 may also include a water receiving tank 35. The drain outlet 811 of the water outlet 304 may be located above or inside the water receiving tank 35. The water receiving tank 35 has a drain outlet 351 connected to the second cylinder 2 or the drainage assembly 7. Through the above structural design, the water receiving tank 35 can serve as a buffer and collection node to receive the discharged waste liquid, intercept impurities in the waste liquid, prevent it from directly entering the drainage system of the whole machine, reduce the risk of blockage, and prevent liquid backflow into the receiving cavity 33, further improving safety and stability. At the same time, the water receiving tank 35 can also temporarily store excess waste liquid to prevent blockage or backflow caused by excessive instantaneous flow. In addition, the height difference between the water receiving tank 35 and the shell 30, combined with the siphon structure 8, can ensure the stable and continuous discharge of waste liquid.

[0077] In addition, a vent hole, identical to the outside, can be provided at the top of the housing 30 or at a height that does not affect the normal cleaning process. The height of the vent hole can be greater than the maximum height of the liquid level during the cleaning process. For example, the height of the vent hole can be higher than the top of the siphon structure 8 to ensure the siphon process. This disclosure is not limited thereto.

[0078] In some embodiments, the drainage assembly 7 includes a first pipe 71, a drain pump 72, and a second pipe 73 connected in sequence. The end of the first pipe opposite to the drain pump 72 is connected to the second drum 2. The second pipe 73 connects the drain pump 72 to the outside of the laundry processing device. The drain outlet 351 is connected to the first pipe 71, the second pipe 73, or the drain pump 72 via a drain pipe 38. Thus, when the second drum 2 drains, the drain pump 72 discharges the water inside the second drum 2. The ultrasonic washing device can utilize the drainage system of the second drum 2 itself for drainage; that is, the water in the water receiving tank 35 can be discharged through the drain pipe 38 via the first pipe 71, the second pipe 73, or the drain pump 72. Exemplarily, the drain pipe 38 can be connected to any one of the first pipe 71, the second pipe 73, or the drain pump 72.

[0079] For example, such as Figure 3As shown, the garment processing equipment may include a water inlet distribution component 6. The water inlet distribution component 6 is connected to the water inlet 303 of the housing 30 through a water inlet pipe 62. The drain outlet 351 of the water receiving tank 35 is connected to the second pipeline 73 through a water outlet pipe 38. The water inlet distribution component 6 may also include an electrically controlled valve for controlling the water inlet pipe 62. In this way, when the user needs to perform a washing operation, the water inlet end of the water inlet distribution component 6 can be connected to a tap through the water inlet pipe. The user can selectively control the opening and closing of the water inlet pipe 62 by controlling the electrically controlled valve. For example, when the user needs to use the ultrasonic washing device 3, the user can open the water inlet pipe 62 by controlling the electrically controlled valve, so that the water flows through the water inlet 303 of the housing 30 into the receiving cavity 33 to perform the washing operation. After washing, the wastewater is discharged through the water outlet 304.

[0080] The electrically controlled valve can be a multi-unit electromagnetic inlet valve. This disclosure is not limited thereto.

[0081] Of course, the aforementioned water inlet distribution component 6 and drain pump 72 can both be connected to the control system signal of the whole machine. Users can control the water inlet distribution component 6 and drain pump 72 through the human-machine interface. These technologies are existing mature technologies and will not be described in detail here.

[0082] In some feasible embodiments, the drainage assembly 7 may include a first pipe 71, a drainage pump 72, and a second pipe 73 connected in sequence. The end of the first pipe 71 away from the drainage pump 72 is connected to the second cylinder 2. The second pipe 73 connects the drainage pump 72 and the outside of the garment processing equipment. The water outlet 304 can be connected to the first pipe 71, the second pipe 73, or the drainage pump 72 via the water outlet pipe 38. Thus, in embodiments that do not employ the siphon structure 8 and the water receiving tank 35, the cleaning liquid in the receiving cavity 33 can be discharged through the water outlet 304, the water outlet pipe 38, the first pipe 71, or the second pipe 73, improving the integration of the garment processing equipment.

[0083] The ultrasonic washing device 3 may also exclude the siphon structure 8. The water outlet 304 of the receiving cavity 33 is directly connected to the receiving cavity 33 and directly connected to the first pipeline 71, the second pipeline 73, or the drain pump 72 through the water outlet pipe 38. For example, the water outlet 304 is configured as a drain outlet, which is connected to the water outlet pipe 38. The water outlet pipe 38 may be equipped with a valve with an adjustable opening. The drainage flow rate is adjusted by controlling the valve opening. For example, when the ultrasonic washing device 3 needs to drain, the valve on the water outlet pipe 38 can be opened. When the water outlet pipe 38 is connected to the first pipeline 71, the drain pump 72 can be used for drainage. When the water outlet pipe 38 is connected to the second pipeline 73, another drain pump can be added to the water outlet pipe 38 for drainage. Alternatively, the water outlet pipe 38 can be directly connected to the drain pump 72 for direct drainage.

[0084] The second cylinder 2 may include an outer cylinder 21, and a first pipe 71 is connected to the outer cylinder 21 to communicate with the inner side of the outer cylinder 21.

[0085] In some feasible ways, for example, refer to Figures 4 to 13 As shown, the siphon structure 8 can be located at the end of the housing 30 opposite to the first opening 34. Through reasonable layout optimization design, the siphon structure 8 is located away from the first opening 34, that is, away from the user's access area to reduce accidental touches and avoid damage to the siphon structure 8 caused by human factors. At the same time, it also avoids interference with the access of the items to be washed by the siphon structure 8, and has greater reliability and stability in use.

[0086] In some feasible ways, for example, refer to Figures 4 to 13 As shown, the pull-out member 31 may have a support portion 310 for carrying the items to be washed, and the support portion 310 has multiple through holes through which the cleaning fluid flows. The support portion 310 can provide storage space for the items to be washed, and the porous design allows the cleaning fluid to submerge the items to be washed, improving the comprehensiveness of the cleaning and enhancing the cleaning effect.

[0087] For example, the carrier portion 310 may include a mesh structure, and the mesh openings of the mesh structure may be through holes. For instance, the carrier portion 310 may be constructed as a carrier cavity or a carrier basket, which facilitates the implementation of a closed anti-loss cleaning mode or a mesh basket-style high-transparency comprehensive cleaning mode for items such as jewelry and baby socks, respectively, achieving better adaptability while ensuring protection.

[0088] The material of the mesh structure can be adapted to meet specific needs; for example, the mesh structure can be a metal filter or a soft filter. Furthermore, the selected filter can possess corrosion-resistant properties, such as resistance to cleaning solutions and water.

[0089] In addition, the mesh size (i.e., pore size) of the mesh structure can be designed as needed to adjust the transmission effect of the shock waves generated by the ultrasonic washing device 3 on the cleaning fluid.

[0090] The support portion 310 may have a top surface for supporting the item to be washed and a bottom surface opposite to the top surface, with multiple through holes penetrating the top and bottom surfaces. The ultrasonic transducer 32 may be located below the support portion 310. In this way, the ultrasonic waves generated by the ultrasonic transducer 32 can be effectively transmitted to the item to be washed through the through holes, thereby ensuring a uniform distribution of ultrasonic energy in the cleaning fluid and enhancing the cleaning effect. In addition, the design of multiple through holes facilitates the flow of the cleaning fluid, promotes the formation and collapse of bubbles during the cleaning process, thereby improving the detergency and cleaning efficiency.

[0091] In some feasible embodiments, the top surface of the support portion 310 can be recessed downward to form a placement groove 3101. The placement groove 3101 is used to place the item to be washed. The placement groove 3101 can limit and protect the item to be washed, preventing it from moving and colliding with the housing 30 during the washing process, thus improving the reliability and safety of use.

[0092] The shape of the placement groove 3101 can be adjusted according to actual needs. For example, the placement groove 3101 can be an arc-shaped groove with a semi-circular cross-section, or it can be a rectangular groove with a rectangular cross-section. This disclosure does not impose specific limitations on this, and those skilled in the art can adjust the shape of the placement groove 3101 according to the size of the item to be washed.

[0093] In some feasible ways, for example, refer to Figures 4 to 13 As shown, the pull-out component 31 may include a cover 311, and a support portion 310 is connected to the side of the cover 311 facing the first opening 34. The cover 311 is used to openably seal the first opening 34. The garment handling device includes a front panel (not shown in the figure), which has a second opening (not shown in the figure) through which the pull-out component 31 moves. The cover 311 can cover the second opening. Through the above structural design, the cover 311 can form a reliable seal on the second opening when the pull-out component 31 moves into the receiving cavity 33, effectively preventing external contaminants from entering the receiving cavity 33, avoiding leakage of cleaning liquid or water, and improving the overall appearance of the machine. In addition, the exposed cover 311 facilitates user operation of the pull-out component 31, enabling quick access to the garments to be washed.

[0094] The cover 311 may also be provided with a handle to facilitate user operation of the pull-out component 31. For example, the cover 311 and the pull-out component 31 may be constructed as a single piece to enhance the overall structural strength and prevent gaps between the cover 311 and the pull-out component 31, thereby preventing leakage of cleaning fluid and water.

[0095] To further enhance the safety of the ultrasonic washing device 3 during the washing process, a first locking structure 37 may be provided on the cover 311, and a second locking structure that can cooperate with the first locking structure 37 may be provided on the housing 30. When the cover 311 seals the opening, the first locking structure 37 and the second locking structure can lock the position of the cover 311, preventing displacement of the cover 311 relative to the housing 30, and further ensuring the sealing effect of the cover 311 on the first opening 34 and the second opening. For example, the first locking structure 37 and the second locking structure may be a snap-fit ​​structure that can cooperate with each other, or the first locking structure 37 and the second locking structure may be a threaded structure that can cooperate with each other, or one of the first locking structure 37 and the second locking structure may include a permanent magnet, and the other may include a metal body or another permanent magnet that can magnetically cooperate with the permanent magnet. This disclosure does not specifically limit the specific application of these features.

[0096] In some feasible ways, for example, refer to Figures 4 to 13 As shown, at least one of the cover 311 and the housing 30 may be provided with a sealing part 36. The sealing part 36 can seal and fit against the other of the cover 311 and the housing 30, and the sealing part 36 is arranged around the first opening 34. By providing the sealing part 36, a stable and reliable liquid-tight and air-tight barrier can be formed between the cover 311 and the housing 30 to suppress the leakage of cleaning fluid, the escape of odors, etc., and reduce the splashing of cleaning fluid and noise pollution caused by the operation of the ultrasonic cleaning device 3, thus improving the reliability and safety of use.

[0097] Furthermore, both the cover 311 and the housing 30 may be provided with sealing portions 36, which are sealed and fitted together. The sealing portions 36 are arranged around the first opening 34 to further improve the sealing effect. This disclosure is not limited thereto.

[0098] The sealing part 36 can be constructed in any suitable manner. For example, the sealing part 36 may include a sealing ring or a sealing gasket. For example, the sealing part 36 may be made of a corrosion-resistant rubber material to better reduce the generation of gaps and ensure the sealing effect of the cover 311 on the receiving cavity 33.

[0099] In some feasible ways, for example, refer to Figures 4 to 13As shown, one of the pull-out component 31 and the housing 30 may be provided with a guide portion 307, and the other may be provided with a guide mating portion 312. The guide portion 307 and the guide mating portion 312 are slidably engaged to guide the pull-out component 31 to be movably inserted into the housing 30. By providing the guide portion 307 and the guide mating portion 312 to guide the pull-out component 31, directional guidance and effective support can be provided during the reciprocating pull-out sliding process of storing and retrieving the item to be washed, reducing jamming and wear, improving load-bearing stability and smoothness, effectively preventing deviation during movement from affecting the sealing performance, and thus improving the reliability of use.

[0100] For example, the guide portion 307 may include a track that extends along the pulling direction of the pull-out member 31, and the guide mating portion 312 may include a slide rod that extends along the pulling direction of the pull-out member 31 and is slidably connected to the track. Of course, the guide portion 307 may also include a slider, and the guide mating portion 312 may also be provided with a groove for sliding connection with the slider. This disclosure is not limited to these, as long as the above functions can be achieved.

[0101] In some exemplary embodiments, guide mating portions 312 are provided on both opposite sides of the support portion 310. These guide mating portions 312 are connected to the cover 311 to enhance the structural stability of the pull-out member 31. Additionally, corresponding guide portions 307 are provided on opposite sides of the housing 30, and the guide mating portions 312 can be slidably supported on the guide portions 307. Figure 11 An exemplary embodiment is shown in which the guide mating part 312 is slidably supported on the guide part 307.

[0102] In some feasible ways, for example, refer to Figures 4 to 6 As shown, the portion of the housing 30 that fits into the ultrasonic transducer 32 is a metal part 305. The ultrasonic transducer 32 is connected to the side of the metal part 305 facing away from the receiving cavity 33. The inner surface of the metal part 305 facing the receiving cavity 33 is used to contact the cleaning fluid. Through the above structural design, the metal part 305 can provide good transmission conditions for the vibrations released by the ultrasonic transducer 32. The inner surface of the metal part 305 is in direct contact with the cleaning fluid, which can improve cavitation efficiency and cleaning intensity. At the same time, the good thermal conductivity of the metal can help dissipate heat and improve the reliability and safety of use. In addition, the metal part 305 can provide good fixation for the ultrasonic transducer 32, increasing the stability of the ultrasonic transducer 32 and reducing energy attenuation.

[0103] The metal part 305 can be made of, for example, stainless steel, aluminum alloy or titanium alloy.

[0104] The thickness of the metal part 305 can be matched to the driving power of the ultrasonic transducer 32 or adapted to both. This disclosure is not limited thereto.

[0105] In some feasible ways, for example, refer to Figures 4 to 11 As shown, the metal part 305 has a mounting groove for mounting the ultrasonic transducer 32. The mounting groove provides mounting space for the ultrasonic transducer 32, ensuring a flat and secure mounting, reducing the occupancy of external space, increasing the effective contact area, and thus improving the cleaning effect.

[0106] The ultrasonic transducer 32 can be installed in any suitable manner. For example, the ultrasonic transducer 32 can be embedded in a mounting groove, or it can be connected to the mounting groove by an adhesive such as epoxy resin, or it can be connected to the mounting groove by a coupling agent such as high-temperature silicone grease or a special gel. This disclosure is not limited thereto.

[0107] In some feasible embodiments, the housing 30 may include a housing portion connected to the metal portion 305, which may be injection molded integrally with the housing portion. The housing portion may be made of any suitable plastic material, and this disclosure does not specifically limit it. Plastic materials have the advantage of being lightweight and can be connected to the metal portion 305 by injection molding. In this way, through integrated design, the number of unnecessary parts and the generation of assembly gaps can be reduced, effectively improving sealing performance, structural rigidity and vibration resistance.

[0108] For example, Figures 4 to 11 As shown, the housing may include an upper housing 301 and a lower housing 302 that are mated together. The upper housing 301 and the lower housing 302 form a receiving cavity 33 and a first opening 34. The metal part 305 is injection molded integrally with the lower housing 302. This integrated design reduces the number of parts and assembly gaps, lowers the risk of leakage, improves structural rigidity and vibration resistance, and also reduces processing difficulty.

[0109] In some feasible ways, for example, refer to Figure 3 The garment processing equipment includes a water inlet pipe 62 connected to the receiving cavity 33, and an electrically controlled valve is installed on the water inlet pipe 62. By adjusting the opening degree and opening time of the electrically controlled valve, the amount of water entering the receiving cavity 33 can be controlled, preventing excessive water volume from causing the cleaning solution in the receiving cavity 33 to overflow and be wasted. Alternatively, as another example, the housing 30 can also be equipped with a sensor for detecting the liquid level in the receiving cavity 33. The sensor's detection data can obtain the water level information in the receiving cavity 33, further controlling the opening and closing of the electrically controlled valve.

[0110] For example, the garment handling equipment disclosed herein may be a washing machine or a washer-dryer combo, etc. This disclosure is not limited thereto.

[0111] The preferred embodiments of this disclosure have been described in detail above with reference to the accompanying drawings. However, this disclosure is not limited to the specific details of the above embodiments. Within the scope of the technical concept of this disclosure, various simple modifications can be made to the technical solutions of this disclosure, and these simple modifications all fall within the protection scope of this disclosure.

[0112] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, this disclosure will not describe the various possible combinations separately.

[0113] Furthermore, various different embodiments of this disclosure can be combined in any way, as long as they do not violate the spirit of this disclosure, they should also be regarded as the content disclosed in this disclosure.
