Description

Technical Field

[0001] This disclosure relates to the field of clothing processing technology, and in particular to an ultrasonic washing device and clothing processing equipment. Background Technology

[0002] As living standards continue to improve, people's demand for cleaning jewelry such as diamond rings, necklaces, and watches is constantly increasing. Ultrasonic cleaning devices are commonly used for this purpose. Most existing ultrasonic cleaning devices employ a flip-top design. When retrieving items from the device, sufficient vertical space is required to allow for the flip-top to open and close. This design limits the use of ultrasonic cleaning devices to independent operation, making integration with other cleaning devices, such as garment washing machines, difficult. This hinders the integration with smart home technology's "multi-functional" requirements and falls short of mainstream market trends. Utility Model Content

[0003] The purpose of this disclosure is to provide an ultrasonic washing device and a garment processing equipment to solve the problem in the related art that ultrasonic washing devices can only be used independently and are difficult to integrate with other washing devices.

[0004] This disclosure provides an ultrasonic washing apparatus, comprising: A housing having a receiving cavity and an opening communicating with the receiving cavity, the receiving cavity being capable of containing cleaning fluid; A pull-out component, movably inserted into the receiving cavity through the opening, the pull-out component having a support portion for carrying the item to be washed, the support portion having a plurality of through holes for the flow of the cleaning fluid; and An ultrasonic transducer is connected to the housing.

[0005] In some possible implementations, the ultrasonic transducer is located below the support portion. This allows the shock waves generated by the cleaning fluid to be directly transmitted into the support portion through the through-hole, shortening the vibration propagation path and improving the vibration efficiency of the ultrasonic transducer.

[0006] In some possible implementations, the support portion is provided with a placement groove for placing the item to be washed. The depth of the placement groove ensures that the item to be washed can be immersed in the cleaning solution when placed in the groove. Simultaneously, the walls of the placement groove can limit and protect the item to be washed, making it more stable during the washing process.

[0007] In some possible implementations, the support portion includes a mesh structure with through-holes in the mesh. The mesh size can be designed as needed to facilitate the transmission of shock waves generated by the cleaning fluid through the ultrasonic transducer.

[0008] In some possible implementations, the pull-out component includes a cover, with the support portion connected to the side of the cover facing the opening. The cover is used to operably seal the opening. The cover prevents cleaning fluid within the receiving cavity from leaking out of the opening, ensuring the cavity's airtightness.

[0009] In some possible implementations, one of the cover and the housing is provided with a sealing portion capable of sealingly fitting the other of the cover and the housing, the sealing portion being arranged around the opening; or; Both the cover and the housing are provided with sealing portions. The sealing portions on the cover and the housing are tightly fitted together, and the sealing portions are arranged around the opening. The sealing portions can better reduce the generation of gaps and ensure the sealing effect of the cover on the receiving cavity.

[0010] In some possible implementations, the cover is provided with a first locking structure, and the housing is provided with a second locking structure that can cooperate with the first locking structure. The first and second locking structures can lock the position of the cover, preventing displacement of the cover relative to the housing and further ensuring the sealing effect of the cover on the receiving cavity.

[0011] In some possible implementations, one of the pull-out member 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 are slidably engaged to guide the pull-out member to be movably inserted into the housing. The guide portion and the guide mating portion enable the pull-out member to be movably inserted into the receiving cavity through the opening.

[0012] In some possible implementations, the ultrasonic transducer is disposed inside the housing. This isolates the ultrasonic transducer from the external environment, preventing its influence. Simultaneously, the housing protects the transducer, extending its service life, improving the overall integration and safety of the machine, and optimizing the sound wave transmission path for enhanced cleaning performance.

[0013] In some possible implementations, the ultrasonic transducer is disposed outside the housing. This facilitates heat dissipation for the ultrasonic transducer, eliminates the need for waterproofing, optimizes wiring layout, reduces wiring complexity, and simplifies maintenance and replacement. Furthermore, when the ultrasonic transducer requires maintenance, the housing of the ultrasonic cleaning equipment does not need to be disassembled; only the ultrasonic transducer needs to be replaced, significantly reducing maintenance costs and time.

[0014] 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. In this way, the ultrasonic transducer is connected to the housing via the metal part. The metal part is generally made of metal, which has high rigidity and can better protect and fix the ultrasonic transducer, increasing its stability, reducing energy attenuation, and ensuring efficient energy transfer.

[0015] In some possible implementations, the metal portion has a mounting groove for mounting the ultrasonic transducer. This allows at least a portion of the ultrasonic transducer to be accommodated within the mounting groove, resulting in less of the ultrasonic transducer protruding from the metal portion, or the ultrasonic transducer not protruding at all, thus reducing the space occupied by the ultrasonic transducer.

[0016] In some possible implementations, the housing includes a housing portion connected to the metal portion; The metal part and the housing part are injection molded as a single unit. This facilitates the production and processing of the housing. Furthermore, the integral injection molding of the metal part and the housing part reduces the number of unnecessary components and assembly gaps, effectively improving structural rigidity and vibration resistance. The ultrasonic washing device can be highly integrated, improving assembly efficiency.

[0017] In some possible implementations, the housing is provided with a water inlet and a water outlet, both communicating with the receiving cavity. Cleaning fluid can be supplied to the receiving cavity through the water inlet, which can clean the workpiece, while the water outlet can discharge the cleaning fluid.

[0018] 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 a stable and continuous discharge of the cleaning fluid.

[0019] 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.

[0020] 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.

[0021] 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.

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

[0023] On the other hand, this disclosure also provides a garment processing device, including the ultrasonic washing apparatus described in any one of the above.

[0024] In some possible implementations, the garment processing device includes a first drum and a second drum, with the first drum located above the second drum, and the ultrasonic washing device located below the first drum or below the rotation axis of the first drum. That is, the garment processing device has at least two drums, which can be operated independently by the user. The user can adjust the washing program and water temperature separately as needed to accommodate different types of clothing, making the garment processing device more convenient to use.

[0025] In some possible implementations, the ultrasonic washing device is located above the second drum or above the rotation axis of the second drum. This allows the ultrasonic washing device to be positioned between the two drums, making efficient use of the gap between them and enabling the ultrasonic washing device to be integrated into the garment processing equipment without occupying additional space.

[0026] In some possible implementations, the outer diameter of the first cylinder is smaller than the outer diameter of the second cylinder; and / or, The system comprises two first drums, with their central axes located on opposite sides of the vertical plane containing the central axis of the second drum. At least one first drum is equipped with the ultrasonic washing device. This allows the second drum to be used for washing large garments such as coats and overcoats, while the first drum can be specifically used for smaller items like underwear and socks. This partitioned design avoids mixing different types of clothing, reduces the risk of cross-contamination, and improves washing efficiency. The two first drums further enhance the functionality of the garment processing equipment, allowing for further partitioning of smaller garments and preventing the mixing of different types of small items.

[0027] In some possible implementations, the water outlet of the ultrasonic washing device, which communicates with the receiving cavity, is connected to the interior of the second drum, and / or the water outlet is connected to a drainage assembly on the second drum. That is, the water discharged by the ultrasonic washing device can be drained through the built-in drainage structure within the garment processing equipment. When the ultrasonic washing device is integrated into the garment processing equipment, an additional drainage structure is no longer needed, further reducing the volume occupied by the ultrasonic washing device.

[0028] 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 the second cylinder. The second pipe connects the drain pump to the outside of the garment processing equipment. The water 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.

[0029] In some possible implementations, the garment handling device includes a water inlet pipe communicating with the receiving cavity, and the water inlet pipe is equipped with an electrically controlled valve; and / or, The housing is equipped with a sensor for detecting the liquid level inside the receiving cavity. 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 levels from overflowing and wasting cleaning fluid. The water level inside the receiving cavity can be obtained from the sensor's detection data, and the opening and closing of the electrically controlled valve can be further controlled based on the water level.

[0030] The technical solutions provided by the embodiments of this disclosure may include the following beneficial effects: Compared to the flip-top structure of ultrasonic washing devices in related technologies, the ultrasonic washing device of this application features a drawer-type structure where the pull-out component is movably inserted into the receiving cavity through an opening. During use, the pull-out component only requires linear translation and occupies a small, rectangular space similar in size to itself, without occupying vertical space. This results in a compact structure with minimal space requirements, facilitating integration with other washing devices, such as garment processing equipment. When the ultrasonic washing device needs to be integrated with garment processing equipment, it can be directly installed within the equipment with the opening located on its surface. When the ultrasonic washing device is needed, the pull-out component can be pulled out through the opening, occupying space outside the garment processing equipment without taking up space inside.

[0031] The garment processing device provided in this disclosure has the same technical effect as the ultrasonic washing device in the above-described technical solutions, and will not be described in detail here to avoid unnecessary repetition; other features and advantages of this disclosure will be described in detail in the following detailed description section. It should be understood that the above general description and the following detailed description are merely exemplary and explanatory, and do not limit this disclosure. Attached Figure Description

Detailed Implementation

[0035] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0040] As living standards continue to improve, people's demand for cleaning jewelry such as diamond rings, necklaces, and watches is constantly increasing. People generally use ultrasonic cleaning devices to clean their jewelry. Ultrasonic cleaning devices convert electrical energy into high-frequency vibrations through a transducer, generating shock waves that impact the surface of the jewelry, thereby removing dirt. Most existing ultrasonic cleaning devices use a flip-top structure, requiring a large space to accommodate the opening and closing. When retrieving jewelry from the device, the cover needs to be opened and flipped at a certain angle. During this process, the cover's rotation creates an arc trajectory, requiring a fan-shaped space above and to the sides of the ultrasonic cleaning device. Furthermore, the device needs to remain open. This structure results in a large space requirement for ultrasonic cleaning devices, limiting their use to standalone applications and making integration with other cleaning devices, such as garment washing machines, difficult. This also hinders their ability to meet the "multi-functional" needs of smart homes and is out of step with mainstream market trends.

[0041] To address the aforementioned issues, the solution presented in this application will be described in detail below with reference to the accompanying drawings.

[0042] Reference Figures 1 to 8 This disclosure provides an ultrasonic washing device 1, including a housing 11, a pull-out component 12, and an ultrasonic transducer 13.

[0043] The housing 11 has a receiving cavity 111 and an opening 112 communicating with the receiving cavity 111, the receiving cavity 111 being capable of containing cleaning fluid. It is understood that the type of cleaning fluid is not limited in this application; the cleaning fluid can be changed depending on the item to be cleaned, which can be items such as jewelry, watches, and eyeglasses mentioned above. For example, when using the ultrasonic cleaning device 1 of this application to clean a watch, a cleaning fluid that will not corrode the watch can be used; when using the ultrasonic cleaning device 1 of this application to clean jewelry, a cleaning fluid that will not corrode the jewelry can be used. In some possible embodiments, water can also be used as the cleaning fluid.

[0044] The pull-out member 12 is movably inserted into the receiving cavity 111 through the opening 112. The pull-out member 12 has a supporting portion 121 for carrying the item to be washed, and the supporting portion 121 has multiple through holes 1213 for the flow of cleaning fluid. Thus, the receiving cavity 111 can also accommodate the pull-out member 12 and the item to be washed carried within the pull-out member 12. When the pull-out member 12 is placed in the receiving cavity 111, the pull-out member 12 can be immersed in the cleaning fluid. Furthermore, the cleaning fluid can enter the supporting portion 121 through the through holes 1213, allowing the item to be washed within the supporting portion 121 to be immersed in the cleaning fluid, ensuring the cleaning effect on the item to be washed. To avoid the lines of the through holes 1213 in the drawings excessively affecting the simplicity of the drawings, in this application, only... Figure 7 The through hole 1213 is shown in the diagram, but it is omitted from the support portion 121 in other figures. It is understood that the omission of the through hole 1213 in the support portion 121 in other figures does not mean that the support portion 121 in those other figures does not have the through hole 1213. Furthermore, Figure 7 The size and position of the through hole 1213 are for illustrative purposes only and do not represent the actual size and position.

[0045] Meanwhile, the pull-out member 12 is movably inserted into the receiving cavity 111 through the opening 112, so that the ultrasonic washing device 1 is formed into a drawer-type structure. This drawer-type structure can constrain the movement of the pull-out member 12 to a single linear dimension. That is to say, the pull-out member 12 only needs to be linearly translated and only needs a strip space similar to its own size. Compared with the flip-top structure of ultrasonic washing devices in related technologies, the ultrasonic washing device 1 in this application will not occupy the space in the height direction, nor does it need to reserve a large fan-shaped space.

[0046] An ultrasonic transducer 13 is connected to the housing 11. The ultrasonic transducer 13 generates shock waves in the cleaning fluid through its own vibration. The housing 11 protects and fixes the ultrasonic transducer 13, increasing its stability, preventing vibration loss, and improving its vibration efficiency. Simultaneously, a portion of the housing 11 can also vibrate along with the ultrasonic transducer 13, further impacting the cleaning fluid within the receiving cavity 111. The through-hole 1213 on the support portion 121 ensures that the shock waves from the cleaning fluid in the receiving cavity 111 are transmitted to the support portion 121, guaranteeing that the cleaning fluid impacts the workpiece to be cleaned and ensuring effective cleaning.

[0047] Compared to the flip-top structure of ultrasonic washing devices 1 in related technologies, the ultrasonic washing device 1 of this application features a drawer-type structure. The drawer-type component 12 is movably inserted into the receiving cavity 111 through the opening 112. During use, the drawer-type component 12 only requires linear translation and occupies only a strip of similar size, without occupying vertical space. This results in a compact structure, small footprint, and minimal space requirement, making it easier to integrate with other washing devices, such as a garment processing device 2. When the ultrasonic washing device 1 needs to be integrated with the garment processing device 2, it can be directly installed inside the garment processing device 2 with the opening 112 located on its surface. When the ultrasonic washing device 1 is needed, the drawer-type component 12 can be pulled out through the opening 112, occupying space outside the garment processing device 2 without encroaching on its interior space.

[0048] In some embodiments, the ultrasonic transducer 13 may be located below the support portion 121. In this way, the ultrasonic transducer 13 allows the shock waves generated by the cleaning fluid to be directly transmitted into the support portion 121 through the through hole 1213, shortening the vibration propagation path and improving the vibration efficiency of the ultrasonic transducer 13.

[0049] The support portion 121 may be provided with a placement groove 1214 for placing the item to be washed. The depth of the placement groove 1214 ensures that the item to be washed can be immersed in the cleaning solution when placed in the placement groove 1214. At the same time, the walls of the placement groove 1214 can limit and protect the item to be washed, making the item more stable during the washing process. It is understood that the shape of the placement groove 1214 is not specifically limited in this application, but can be referred to... Figure 3In some embodiments, the placement groove 1214 can be an arc-shaped groove with a semi-circular cross-sectional shape. In other embodiments, the placement groove 1214 can also be a rectangular groove with a rectangular cross-sectional shape.

[0050] The carrier portion 121 may include a mesh structure with through holes 1213. In some embodiments, the mesh structure may be a metal filter screen; in other embodiments, it may be a soft filter screen, such as one made of PP material. Furthermore, the selected filter screen may have corrosion-resistant properties, such as resistance to washing liquids and water. The mesh size of the mesh structure can be designed as needed to facilitate the transmission of shock waves generated by the cleaning liquid through the ultrasonic transducer 13.

[0051] The pull-out component 12 may include a cover 122, with a support portion 121 connected to the side of the cover 122 facing the opening 112. The cover 122 is used to operably seal the opening 112. Through the cover 122, the cleaning fluid in the receiving cavity 111 will not flow out from the opening 112, ensuring the sealing of the receiving cavity 111. Simultaneously, the cover 122 is mounted on the pull-out component 12, allowing the user to adjust the position of the pull-out component 12 by pushing and pulling the cover 122. Furthermore, the cover 122 may also be provided with a handle for easy pushing and pulling. The cover 122 can be integrated with the pull-out component 12 as a single piece, ensuring the connection strength between the cover 122 and the pull-out component 12, and preventing the formation of gaps between the cover 122 and the pull-out component 12, thus preventing the cleaning fluid from flowing between the cover 122 and the pull-out component 12.

[0052] To reduce the gap between the cover 122 and the opening 112 and prevent the cleaning fluid in the receiving cavity 111 from flowing out of the opening 112, one of the cover 122 and the housing 11 may be provided with a sealing part 14. The sealing part 14 can seal and fit against the other of the cover 122 and the housing 11, and the sealing part 14 is arranged around the opening 112; or, both the cover 122 and the housing 11 may be provided with sealing parts 14, and the sealing part 14 on the cover 122 and the sealing part 14 on the housing 11 are sealed and fitted together, and the sealing part 14 is arranged around the opening 112. When the cover 122 is provided with a sealing part 14, the sealing part 14 on the cover 122 can fit against the surface of the housing 11. When the housing 11 is provided with a sealing part 14, the sealing part 14 on the housing 11 can fit against the surface of the cover 122. When both the cover 122 and the housing 11 are provided with sealing parts 14, the sealing part 14 on the cover 122 can fit into the sealing part 14 on the housing 11. The sealing part 14 here can be made of corrosion-resistant rubber material. The rubber material is elastic, and the elastic sealing part 14 can better reduce the generation of gaps and ensure the sealing effect of the cover 122 on the receiving cavity 111.

[0053] After the cover 122 seals the opening 112, in order to prevent the cover 122 from shifting, in some embodiments, the cover 122 may be provided with a first locking structure 1221, and the housing 11 may be provided with a second locking structure 113 that can cooperate with the first locking structure 1221. See details for further information. Figure 2 When the cover 122 seals the opening 112, the first locking structure 1221 and the second locking structure 113 can lock the position of the cover 122, preventing the cover 122 from shifting relative to the housing 11, and further ensuring the sealing effect of the cover 122 on the receiving cavity 111. For example, the first locking structure 1221 and the second locking structure 113 can be mutually cooperating snap-fit ​​structures, or they can be mutually cooperating threaded structures, or one of the first locking structure 1221 and the second locking structure 113 can include a permanent magnet, and the other can include a metal body or another permanent magnet capable of magnetically engaging with the permanent magnet. This disclosure does not specifically limit the specific application of these features.

[0054] In some embodiments, one of the pull-out member 12 and the housing 11 may be provided with a guide portion 123, and the other with a guide mating portion 124. The guide portion 123 and the guide mating portion 124 are slidably engaged to guide the pull-out member 12 to be movably inserted into the housing 11. By providing the guide portion 123 and the guide mating portion 124 to guide the pull-out member 12, directional guidance and effective support can be provided during the reciprocating pull-out sliding process of storing and retrieving the items 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.

[0055] For example, the guide portion 123 may include a track that extends along the pulling direction of the pull-out member 12, and the guide mating portion 124 may include a slide rod that extends along the pulling direction of the pull-out member 12 and is slidably connected to the track. Alternatively, the guide portion 123 may also include a slider, and the guide mating portion 124 may be provided with a groove that slidably connects to the slider. This disclosure is not limited to these embodiments; any method that achieves the above-described functions is acceptable.

[0056] In some exemplary embodiments, guide mating portions 124 are provided on both opposite sides of the support portion, and the guide mating portions 124 are connected to the cover 122 to enhance the structural stability of the pull-out member 12. Additionally, corresponding guide portions 123 are provided on opposite sides of the housing, and the guide mating portions 124 can be slidably supported on the guide portions 123. Figure 3 and Figure 6 An exemplary embodiment is shown in which the guide fitting 124 is slidably supported on the guide 123.

[0057] In some embodiments, the ultrasonic transducer 13 can be disposed inside the housing 11. In this way, the ultrasonic transducer 13 is isolated from the external environment, avoiding the influence of the external environment on the ultrasonic transducer 13. At the same time, the housing 11 can protect the ultrasonic transducer 13, extend its service life, improve the integration and safety of the whole machine, and optimize the sound wave transmission path to improve the cleaning effect.

[0058] In some embodiments, the ultrasonic transducer 13 can be disposed outside the housing 11. This facilitates heat dissipation for the ultrasonic transducer 13, eliminates the need for waterproofing, optimizes the wiring layout, reduces wiring complexity, and still achieves effective cleaning of the items to be washed. Furthermore, when the ultrasonic transducer 13 requires maintenance, it is not necessary to disassemble the housing 11 of the ultrasonic washing device 1; only the ultrasonic transducer 13 needs to be replaced, significantly reducing maintenance costs and time.

[0059] The portion of the housing 11 that fits against the ultrasonic transducer 13 can be a metal part 114. The ultrasonic transducer 13 is connected to the side of the metal part 114 facing away from the receiving cavity 111, and the inner surface of the metal part 114 facing the receiving cavity 111 is used for contact with the cleaning fluid. In this way, the ultrasonic transducer 13 is connected to the housing 11 via the metal part 114. It can be understood that the metal part 114 here refers to a mounting structure made of metal material, in which case the ultrasonic transducer 13 is positioned outside the housing 11. The metal part 114, made of metal, has high rigidity, which can better protect and fix the ultrasonic transducer 13, increase the stability of the ultrasonic transducer 13, reduce energy attenuation, and ensure efficient energy transfer.

[0060] Furthermore, the metal part 114 can be made of, for example, stainless steel sheet, aluminum alloy sheet or titanium alloy sheet.

[0061] The thickness of the metal part 114 can be matched with the driving power of the ultrasonic transducer 13 or the two can be adapted together; this disclosure does not specifically limit this.

[0062] The metal part 114 may have a mounting groove for mounting the ultrasonic transducer 13. In this way, at least a portion of the ultrasonic transducer 13 can be accommodated in the mounting groove, such that the portion of the ultrasonic transducer 13 protruding from the metal part 114 is small, or the ultrasonic transducer 13 does not protrude from the metal part 114, thereby reducing the space occupied by the ultrasonic transducer 13.

[0063] In some embodiments, the ultrasonic transducer 13 can be embedded in a mounting slot.

[0064] In some embodiments, the ultrasonic transducer 13 can be bonded to the metal part 114 by means of, for example, epoxy resin.

[0065] In some embodiments, a coupling agent, such as high-temperature silicone grease or a special gel, may also be provided between the ultrasonic transducer 13 and the metal part 114 to fill the air gap and ensure efficient energy transfer.

[0066] In some embodiments, the housing 11 may include a housing portion connected to the metal portion 114. The housing portion may include an upper housing 115 and a lower housing 116 that abut against each other, forming a receiving cavity 111 and an opening 112. This makes the housing 11 easier to assemble and disassemble, and also facilitates the manufacturing and processing of the housing 11. Meanwhile, the metal portion 114 can be injection molded integrally with the housing portion. For example, the metal portion 114 can be injection molded integrally with the lower housing 116. This facilitates the manufacturing and processing of the housing 11. Furthermore, the integral injection molding of the metal portion 114 with the housing portion reduces the number of unnecessary parts and assembly gaps, effectively improving sealing performance, structural rigidity, and vibration resistance. The ultrasonic washing device 1 can be highly integrated, improving assembly efficiency.

[0067] In some embodiments, the housing 11 may be made of a corrosion-resistant plastic material to improve corrosion resistance.

[0068] The housing 11 may be provided with a water inlet and a water outlet, both of which are connected to the receiving cavity 111. The water inlet can supply cleaning fluid into the receiving cavity 111, and the cleaning fluid can clean the parts to be cleaned, while the water outlet can discharge the cleaning fluid.

[0069] In some embodiments, the water outlet can 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 111, and the other end is a drain outlet 811. It is understood that the inlet of the siphon channel 81 is connected to the receiving cavity 111, and the drain outlet 811 of the siphon channel 81 is used for drainage. It is understood that siphoning is a fluid dynamics phenomenon that allows liquid to be drawn without the aid of a pump. For example, a liquid at a higher position fills an inverted U-shaped tubular structure called a siphon tube, with its drain outlet located at a lower position. In this structure, 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 to the drain outlet 811. In this application, when the level of the cleaning fluid in the receiving cavity 111 reaches a certain height, the cleaning fluid in the receiving cavity 111 can trigger a siphoning phenomenon through the siphon channel 81, flowing out of the housing 11 from the drain outlet 811 of the siphon channel 81. In other words, the ultrasonic cleaning device 1 in this application can automatically discharge the liquid in the receiving cavity 111 through the siphon channel 81. This eliminates the need for an additional drainage structure (such as a drain pump and water valve) to automatically discharge the cleaning fluid from the housing 11. The ultrasonic cleaning device 1 is smaller in size and occupies less space, making it easier to integrate and arrange. Simultaneously, the height of the bend in the siphon channel 81 determines the maximum water level that the receiving cavity 111 can hold. If the bend in the siphon channel 81 is lower, the maximum water level that the receiving cavity 111 can hold is also lower. (Refer to...) Figure 8 , Figure 7 The arrows indicate the flow path of the cleaning fluid entering the siphon channel 81.

[0070] Understandably, the inlet 810 of the siphon channel 81, that is, the water inlet of the siphon channel 81, must be spaced apart from the bottom of the receiving cavity 111 to ensure that the cleaning fluid in the receiving cavity 111 can enter the siphon channel 81. In other words, a gap must be formed between the water inlet of the siphon channel 81 and the bottom of the receiving cavity 111. (Continue referring to...) Figure 6 In the image, the arrow indicates the location where the gap is formed.

[0071] The height of the drain outlet 811 can be lower than or equal to the lowest point of the liquid in the receiving cavity 111. 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 111, 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 111. This disclosure is not limited thereto.

[0072] In some feasible ways, for example, refer to Figure 8As shown, the siphon channel 81 may include a water inlet section 812 and a drainage section 813. The bottom end of the water inlet section 812 is connected to the receiving cavity 111, and the top end of the water inlet 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 inlet section 812 and the drainage section 813, allowing the liquid in the receiving cavity 111 to be smoothly guided to the water inlet 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, improving the smoothness and reliability of drainage. During the cleaning process of the items to be washed, the height of the cleaning liquid is lower than the height of the connection between the water inlet section 812 and the drainage section 813 to ensure a normal cleaning process without triggering the siphon process. When drainage is required, cleaning fluid can be added to the receiving cavity 111 to raise the liquid level to fill the connection between the water inlet section 812 and the drainage section 813, thereby triggering the siphon process.

[0073] 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 111 and forms at least a partial drainage section 813 between the partition 83 and the inner wall of the receiving cavity 111. 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 111 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.

[0074] 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 111 without needing to connect to the inner wall of the receiving cavity 111. Siphon drainage can be achieved simply through the cooperation of the partition 83 and the cover 82, providing greater flexibility in use.

[0075] In some feasible embodiments, the cover portion 82 can be integrally constructed with the housing 11, for example, it can be integrally constructed with the aforementioned lower housing 116, in order to reduce assembly difficulty and improve assembly efficiency.

[0076] In some possible implementations, for example, refer to Figure 4 As 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 4 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 82 to connect to or insert into the partition 83, and can also restrict the cover 82 from disengaging from the partition 83 in other directions that are at an angle to the insertion direction.

[0077] In addition, the cover portion 82 can also be bonded or fastened to the housing 11, but this disclosure is not limited thereto.

[0078] Optionally, refer to Figure 6 As shown, a support portion 84 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 111. The cover portion 82 is supported on the support portion 84, so that a gap communicating with the siphon channel 81 is formed between the cover portion 82 and the bottom surface of the receiving cavity 111 as described above. Exemplarily, the support portion 84 may protrude from the bottom wall of the receiving cavity 111, so that there is a gap between the partition portion 83 after installation and the bottom wall of the receiving cavity 111, and the inlet 810 of the water inlet section 812 communicates with the receiving cavity 111. In this way, when drainage is required, the user can operate the water inlet distribution assembly 7 to inject water into the receiving cavity 111 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 11. For example, the partition 83 can be connected to the housing 11 by means of adhesive bonding or fastener connection, depending on the positioning of the support 84. Alternatively, the partition 83 can be integrally constructed with the housing 11, but this disclosure is not limited thereto.

[0079] The support portion 84 may include multiple positioning blocks, each with a slot. The bottom end of the cover portion 82 can engage with the slot to enhance the connection stability between the two. This disclosure is not limited thereto.

[0080] The ultrasonic washing device 1 also includes a water receiving tank 15 connected to the housing 11. The drain outlet 811 of the water outlet is located above or inside the water receiving tank 15, and the water receiving tank 15 has a drain outlet 151. Through the above structural design, the water receiving tank 15 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 111, further improving safety and stability. At the same time, the water receiving tank 15 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 15 and the housing 11, combined with the siphon structure 8, can ensure the stable and continuous discharge of waste liquid.

[0081] In addition, a vent hole, identical to the outside, can be provided at the top of the housing 11 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.

[0082] In one application scenario, when the ultrasonic washing device 1 is applied to the garment processing device 2, the drain outlet 811 of the ultrasonic washing device 1, which is connected to the receiving cavity 111, is connected to the drainage assembly 5 (described below) of the second drum 22 of the garment processing device 2. The drainage assembly includes a first pipe 51, a drain pump 52, and a second pipe 53 connected in sequence. The end of the first pipe 51 away from the drain pump 52 is connected to the second drum 22. The second pipe 53 connects the drain pump 52 and the outside of the garment processing device 2. The drain outlet 151 is connected to the second pipe 53 or the drain pump 52 through the outlet pipe 6. In this way, when the second drum 22 drains, the water in the second drum 22 is discharged by the drain pump 52. The ultrasonic washing device 1 can use the drainage system of the second drum 22 itself to drain water, that is, the water in the receiving tank 15 can be discharged through the outlet pipe 6 via the first pipe 51, the second pipe 53, or the drain pump 52. For example, the water outlet pipe 6 can be connected to any one of the first pipe 51, the second pipe 53, and the drain pump 52.

[0083] For example, such as Figure 10As shown, the garment processing device 2 may include a water inlet distribution component 7, which is connected to the water inlet of the housing 11 via a water inlet pipe 23. The drain outlet 151 of the water receiving tank 15 is connected to the second pipeline 53 via a water outlet pipe 6. The water inlet distribution component 7 may also include an electrically controlled valve for controlling the water inlet pipe 23. In this way, when the user needs to perform a washing operation, the water inlet end of the water inlet distribution component 7 can be connected to a tap via the water inlet pipe 23. The user can selectively control the opening and closing of the water inlet pipe 23 by controlling the electrically controlled valve. For example, when the user needs to use the ultrasonic washing device 1, the user can open the water inlet pipe 23 by controlling the electrically controlled valve, so that the water flows into the receiving cavity 111 through the water inlet of the housing 11 to perform the washing operation. After the washing is completed, the wastewater is discharged through the drain outlet 811.

[0084] The electrically controlled valve can be a multi-unit electromagnetic inlet valve. This disclosure is not limited thereto.

[0085] Of course, the aforementioned water inlet distribution component 7 and drain pump 52 can be connected to the control system signal of the whole machine. Users can control the water inlet distribution component 7 and drain pump 52 through the human-machine interface. These technologies are existing mature technologies and will not be described in detail here.

[0086] Furthermore, as another example, in an embodiment without a siphon channel 81, the water outlet of the receiving cavity 111 is directly connected to the receiving cavity 111 and directly connected to the first pipeline 51, the second pipeline 53, or the drain pump 52 via the water outlet pipe 6. Of course, the water outlet pipe 6 can be equipped with an adjustable valve, and the drainage flow rate can be adjusted by controlling the valve opening. For example, when the ultrasonic washing device 1 needs to drain water, the valve on the water outlet pipe 6 can be opened. When the water outlet pipe 6 is connected to the first pipeline 51, drainage can be carried out using the drain pump 52. When the water outlet pipe 6 is connected to the second pipeline 53, another drain pump 52 can be added to the water outlet pipe 6 for drainage. Alternatively, the water outlet pipe 6 can be directly connected to the drain pump 52 for direct drainage via the drain pump 52.

[0087] On the other hand, refer to Figures 9 to 10 This disclosure also provides a garment processing device 2, including the ultrasonic washing device 1 of any of the above embodiments. The garment processing device 2 can be a washing machine, a washer-dryer combo, etc. The garment processing device 2 provided by this disclosure has the same technical effects as the ultrasonic washing device 1 in the above-described technical solutions, and will not be described in detail here to avoid unnecessary repetition.

[0088] When the ultrasonic washing device 1 of this application is integrated into the garment processing equipment 2, the ultrasonic washing device 1 can be fixedly connected to the outer shell of the garment processing equipment 2.

[0089] The garment processing device 2 may include a first drum 21 and a second drum 22, with the first drum 21 located above the second drum 22. That is, the garment processing device 2 has at least two drums, and the user can operate each of the at least two drums independently, adjusting the washing program and water temperature as needed to suit different types of clothing, making the garment processing device 2 more convenient to use.

[0090] The ultrasonic washing device 1 can be located below the first drum 21 or below the rotation axis of the first drum 21. Further, the ultrasonic washing device 1 can be located above the second drum 22 or above the rotation axis of the second drum 22. This allows the ultrasonic washing device 1 to be positioned between the two drums, making efficient use of the gap between them and integrating it into the garment processing equipment 2 without occupying additional space. It is important to note that while the ultrasonic washing device 1 can make efficient use of the gap between the two drums, the distance between the ultrasonic washing device 1 and the two drums needs to be controlled within a certain range. This avoids the ultrasonic washing device 1 being too close to the drums, affecting their arrangement and use, and also avoids the ultrasonic washing device 1 being too far from the drums, resulting in wasted space. For example, in some possible embodiments, the minimum distance between the outer edge of the ultrasonic washing device 1 and the outer edge of the second drum 22 can be greater than or equal to 15mm, and the minimum distance between the outer edge of the ultrasonic washing device 1 and the outer edge of the first drum 21 can be greater than or equal to 20mm.

[0091] In some embodiments, the outer diameter of the first drum 21 can be smaller than the outer diameter of the second drum 22. This allows the second drum 22 to be used for washing clothes such as coats and jackets, while the first drum 21 can be used specifically for smaller items such as underwear and socks. This partitioned design avoids mixing different types of clothing, reduces the risk of cross-contamination, and improves washing efficiency.

[0092] In some embodiments, there can be two first tubs 21. Two first tubs 21 can further enrich the use of the garment handling device 2, allowing for further partitioning of smaller garments and avoiding mixing different types of smaller garments. Simultaneously, the two central axes of the two first tubs 21 can be located on opposite sides of the vertical plane containing the central axis of the second tub 22, as shown in the reference... Figure 9With the viewpoint facing the front of the garment processing device 2 as a reference, the two central axes of the two first drums 21 can be located to the upper left and upper right of the central axis of the second drum 22, respectively. For the garment processing device 2, the front of the drums, i.e., the direction of the drum openings, allows users to easily pick up and put down garments. This design allows the two first drums 21 to make efficient use of the space above the second drum 22, resulting in a smaller footprint and reduced volume compared to stacking the two first drums 21. An ultrasonic washing device 1 can be installed below at least one first drum 21. Thus, one or more ultrasonic washing devices 1 can be installed, further enriching the functionality and use of the garment processing device 2.

[0093] Exemplarily, in some implementable ways, for example, refer to Figure 9 As shown, the garment processing device 2 may include a mounting plate 3 located at least partially between the first drum 21 and the second drum 22, and the ultrasonic washing device 1 is connected to the mounting plate 3. The mounting plate 3 provides installation conditions for the ultrasonic washing device 1, allowing the ultrasonic washing device 1 to be independent of the first drum 21 and the second drum 22, avoiding mutual interference, improving the stability and safety of the structure, and facilitating subsequent disassembly and maintenance.

[0094] In some feasible ways, continue to refer to Figure 9 The garment processing device 2 may include a frame 4, and the mounting plate 3 may include a first plate 31 and a second plate 32. The first plate 31 is located on the front side of the frame 4 along the front-rear direction of the garment processing device 2, and the second plate 32 is provided on both sides of the frame 4 along the width direction of the garment processing device 2. The ultrasonic washing device 1 is connected to the first plate 31 and one of the second plates 32 respectively. Through the above structural design, the installation position of the ultrasonic washing device 1 can be flexibly adjusted. For example, the loading port of the ultrasonic washing device 1 can be located on the front side or on both sides of the garment processing device 2. In addition, it can be flexibly added according to capacity and functional requirements. For example, two ultrasonic washing devices 1 can be set to correspond to two first drums 21 respectively, so as to further improve the functionality of the whole machine and increase the layout flexibility and reliability of the whole machine.

[0095] In some embodiments, the water outlet of the ultrasonic washing device 1, which communicates with the receiving cavity 111, is connected to a drainage assembly 5 on the second cylinder 22. It is understood that the drainage assembly 5 here actually refers to the drainage structure of the second cylinder 22, and the structure represented by the drainage assembly 5 varies depending on the implementation of the drainage structure of the second cylinder 22. For example, the drainage assembly 5 may include the first pipe 51, the drain pump 52, and the second pipe 53 mentioned above, which will not be described again here. That is, the water discharged by the ultrasonic washing device 1 can be drained through the drainage structure built into the clothing processing device 2. When the ultrasonic washing device 1 is integrated into the clothing processing device 2, no additional drainage structure is needed, further reducing the volume occupied by the ultrasonic washing device 1.

[0096] In some embodiments, the water outlet of the ultrasonic washing device 1, which is connected to the receiving cavity 111, can also be connected to the interior of the second cylinder 22. For example, the second cylinder 22 includes an outer cylinder and an inner cylinder located inside the outer cylinder. The inner cylinder is used to hold and wash or dry clothes, etc. The outer cylinder can be provided with a hole that connects to the inside of the outer cylinder. The water outlet can also be connected to the hole through a pipe for draining the ultrasonic washing device 1.

[0097] In some embodiments, the garment processing device 2 may include a water inlet pipe 23 communicating with the receiving cavity 111, and an electrically controlled valve is provided on the water inlet pipe 23. Thus, by adjusting the opening degree and opening time of the electrically controlled valve, the amount of water entering the receiving cavity 111 can be controlled, preventing excessive water volume in the receiving cavity 111 from overflowing and wasting the cleaning solution. Alternatively, as another example, the housing 11 may also be equipped with a sensor for detecting the liquid level in the receiving cavity 111. The water level in the receiving cavity 111 can be obtained through the sensor's detection data, and the opening and closing of the electrically controlled valve can be further controlled based on the water level in the receiving cavity 111. As described above, when the housing 11 has a separate upper housing 115 and a lower housing 116, refer to... Figure 3 The water inlet pipe 23 can be integrated into the upper housing 115.

[0098] As described above, the ultrasonic washing device 1 can drain water through a siphon channel 81. When the ultrasonic washing device 1 needs to drain water, a certain amount of water or cleaning fluid can be added to the receiving cavity 111 by controlling the electrically controlled valve and the water inlet pipe 23, causing the liquid level in the receiving cavity 111 to rise. After the liquid level rises to the point where it can flow and fill the siphon channel 81, a siphon reaction can be triggered. At this time, the ultrasonic washing device can automatically trigger drainage to discharge the cleaning fluid. In this way, the liquid level of the ultrasonic washing device 1 can be controlled by controlling the opening time of the electrically controlled valve. For example, when the ultrasonic washing device 1 needs to be used for cleaning, the electrically controlled valve on the water inlet pipe 23 can be opened and closed after a first preset time period, so that the liquid level in the receiving cavity 111 is lower than any position above the top of the water inlet section. 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. This position can be preset as the cleaning liquid level for cleaning the item to be washed. At this time, the liquid level in the receiving cavity 111 will not trigger the drainage process, but... After cleaning, the electrically controlled valve can be reopened and held for a second preset time period to raise the liquid level in the receiving cavity 111, triggering a siphon process. The valve can then be closed, and the ultrasonic washing device 1 will automatically drain. During this process, the liquid in the receiving cavity 111 is continuously drawn into the water inlet of the water inlet section until the liquid in the receiving cavity 111 is completely drained 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 level to the top of the water inlet section and enters the drainage section, triggering the siphon effect. In some embodiments of the ultrasonic washing device 1 in this application, it is not necessary to install a water pump or control valve in the drainage method of the receiving cavity 111. Instead, the drainage process is indirectly controlled by the electrically controlled valve on the water inlet pipe 23 in the water supply control mode. This makes the ultrasonic washing device 1 smaller in size and occupies less space, facilitating its use and arrangement. Furthermore, the smaller ultrasonic washing device 1 is also easier to integrate with other washing devices. It is understood that, in this application, the drainage mentioned above actually refers to the discharge of cleaning fluid from the receiving cavity 111. Depending on the type of cleaning fluid, the meaning of "water" in the drainage will vary.

[0099] Other embodiments of this disclosure will readily occur to those skilled in the art upon consideration of the specification and practice of this disclosure.
