[0061] The realization of the purpose, functional features and advantages of this application will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Embodiments of the present invention

[0062] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0063] In the following description, when referring to the accompanying drawings, the same numbers in different drawings denote the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0064] In the description of this application, it should be understood that the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0065] Please refer to Figures 1 to 8. This application provides a garment processing device that can increase the water content of steam, improve the ironing effect, and has a good visual effect.

[0066] The clothing processing device in this embodiment can be a dryer, washing machine, washer-dryer combo, etc. The following description will use a dryer as the clothing processing device in this embodiment. It should be noted that the directional reference numerals F, R, T, and U in the accompanying drawings represent the front, rear, top, and bottom of the clothing processing device, respectively.

[0067] The garment processing in this embodiment includes a housing 100, a garment processing cylinder 10, a dispensing device 20, a steam generator 30, and a fluid supply device 40.

[0068] The outer casing 100 is roughly hexahedral in shape, but a cuboid shape is more common for ease of placement and use. The casing 100 can be made of engineering plastic or metal, offering good insulation and strong impact resistance. A control panel for user operation is located on the front of the casing 100, integrating a touchscreen display and multiple operation buttons. The touchscreen display provides an intuitive and user-friendly interface, allowing users to easily select various garment processing programs, such as regular drying, steam care, and quick drying, to meet different garment materials and processing needs. The multiple operation buttons serve as auxiliary operation methods; users can press these buttons to start, pause, or stop the program, or to make other related settings, such as adjusting drying time and temperature parameters.

[0069] In this embodiment, the garment processing drum 10 is installed inside the outer casing 100 and can be made of stainless steel. Stainless steel is characterized by high strength and corrosion resistance, and can withstand the strong centrifugal force generated by high-speed rotation during garment processing. This ensures that the garment processing drum 10 will not deform or be damaged due to stress during long-term use, thereby guaranteeing the stability and reliability of the equipment. The garment processing drum 10 is generally hollow and cylindrical, and its internal space can be rationally arranged according to the actual needs of garment processing to accommodate garments of different sizes and types, such as large bed sheets and duvet covers, or small shoes.

[0070] During the garment processing, the garment processing drum 10 can rotate. As the drum rotates, the garments move from the bottom to the top along with the rotating drum wall, and then fall back down under the influence of gravity, repeating this cycle. Under the combined action of the rotation of the drum 10 and gravity, the garments are thoroughly dispersed, tumbled, and their posture altered. This movement ensures that the garments are evenly distributed within the drum, guaranteeing uniform heating and drying of all parts of the garments. This avoids localized overheating or uneven drying, significantly improving drying efficiency and effectiveness. It also helps reduce wrinkles, resulting in smoother garments after drying.

[0071] For example, the garment processing equipment also includes a motor, and the garment processing drum 10 is driven by the motor via a belt. The motor, as a power source, transmits power to the garment processing drum 10 through the belt, causing the garment processing drum 10 to rotate at a set speed and direction. This transmission method has the advantages of simple structure, smooth transmission, and low noise, and can ensure that the garment processing drum 10 maintains a stable operating state during rotation.

[0072] In one embodiment, the garment processing device includes a circulating air duct, an air inlet on the rear side of the garment processing cylinder 10, and an air outlet on the front side of the garment processing cylinder 10. The circulating air duct connects the air inlet and the air outlet. The circulating air duct is configured to provide circulating airflow to the inner cavity of the garment processing cylinder 10. The airflow in the circulating air duct can enter the inner cavity of the garment processing cylinder 10 through the air inlet, and the airflow inside the garment processing cylinder 10 can enter the circulating air duct through the air outlet. The airflow can circulate between the circulating air duct and the garment processing cylinder 10.

[0073] In one embodiment, the garment processing device further includes a base 60, which is disposed below the garment processing cylinder 10. The base 60 forms a heat exchange channel, which is part of the circulating air duct.

[0074] The garment processing equipment also includes a heat exchange component located within a heat exchange channel. The heat exchange component is configured to exchange heat with the airflow within the heat exchange channel, thereby dehumidifying and heating. The humid and hot airflow in the garment processing drum 10 enters the heat exchange channel and, after heat and mass exchange with the heat exchange component, is converted into dry and hot airflow. The dry and hot airflow then flows back into the garment processing drum 10 through the air inlet.

[0075] Exemplarily, the heat exchange assembly includes a condenser and an evaporator, and the garment handling equipment also includes a compressor and a throttling device. The compressor, condenser, throttling device, and evaporator are connected by pipes to form a heat pump system, within which the refrigerant can circulate. The airflow in the circulating duct exchanges heat with the refrigerant in the evaporator and condenser to form a dry, hot airflow. The evaporator is configured to cool and dehumidify the humid, hot airflow from the garment handling drum 10 to form a dry, cold airflow; the condenser heats the dry, cold airflow into a dry, hot airflow and returns it to the garment handling drum 10.

[0076] The working principle of a heat pump system is as follows: The compressor draws in low-pressure gaseous refrigerant and compresses it into high-pressure airflow before discharging it. The discharged high-pressure refrigerant enters the condenser, where it transfers heat to the airflow, causing it to condense into a high-pressure liquid. The high-pressure liquid refrigerant then flows through a throttling device to reduce pressure, becoming a low-pressure, low-temperature gas-liquid two-phase mixture that enters the evaporator. The refrigerant in the evaporator absorbs heat from the airflow, becoming a low-pressure gas. This low-pressure gaseous refrigerant is then drawn back into the compressor, and the cycle repeats, achieving heat exchange. In other words, the evaporator is configured to cool and dehumidify the hot, humid airflow from the clothes handling drum 10, forming a dry, cool airflow. The condenser heats this dry, cool airflow into a hot, dry airflow, which then flows back into the clothes handling drum 10. The hot, dry airflow returning to the clothes handling drum 10 comes into contact with the damp clothes, forming a hot, humid airflow again, completing one drying cycle. By repeatedly running this drying cycle, circulating airflow is continuously supplied to the clothes handling drum 10 to dry the clothes.

[0077] For example, both the evaporator and the condenser can be finned tube heat exchangers.

[0078] For example, throttling devices include, but are not limited to, electronic expansion valves.

[0079] In one embodiment, the garment processing apparatus includes a fan configured to drive airflow. Exemplarily, the fan is located within a heat exchange channel. During the drying process, the fan is configured to drive the airflow passing over the garment sequentially through an evaporator and a condenser before blowing it back onto the garment to form a circulating airflow.

[0080] In this embodiment, the dispensing device 20 is connected to the clothing processing drum 10, and the dispensing device 20 has a first supply channel 2201 and a second supply channel 2301. The dispensing device 20 is configured to dispense fluid from the first supply channel 2201 and the second supply channel 2301 into the clothing processing drum 10 in the form of a vapor-liquid mixture. The dispensing device 20 can adopt various structural forms, such as a nozzle or a power pump structure.

[0081] When a nozzle structure is used, the steam and fabric softener are mixed inside the nozzle and then evenly sprayed in a mist onto the clothes inside the garment treatment drum 10. This mist spraying method allows the steam-liquid mixture to fully cover the surface of the clothes, ensuring that every part of the garment comes into contact with the steam and fabric softener, thereby achieving better treatment results. For example, during a steam treatment program, the nozzle can mix hot steam and fabric softener-containing liquid and spray it evenly onto the clothes. The heat and humidity of the steam soften the fabric fibers, while the fabric softener further softens the fibers. The two work synergistically to significantly improve the wrinkle removal effect and softness of the clothes.

[0082] When a power pump structure is adopted, a power source (such as electricity or other energy) provides power to change the flow rate and / or direction of steam, allowing the steam and fabric softener to mix better and enter the garment treatment cylinder 10 in the form of a vapor-liquid mixture. The power pump can control the mixing ratio, dispensing speed, and direction of the steam and fabric softener according to preset programs or user settings, thereby achieving more intelligent garment treatment. For example, for some delicate garment materials, such as silk, the power pump structure can adjust the mixing ratio and dispensing speed of the steam and fabric softener to avoid damage to the garment while achieving a good care effect.

[0083] The steam generator 30 in this embodiment has a steam outlet 301, which is connected to the first supply channel 2201. The steam generator 30 is capable of generating steam, which may include hot steam and cold steam. Hot steam is the high-temperature vaporized form generated after heating by the steam generator 30, with a temperature above 100°C. Cold steam is the mist-like form at room temperature or low temperature after the fluid is dispersed; room temperature refers to a temperature between 20°C and 40°C, and low temperature refers to a temperature below 20°C.

[0084] Furthermore, the steam generator 30 is also configured to provide driving force for the dispensing device 20. During the spraying operation of the dispensing device 20, the steam generator 30 enables the fluid supply device 40 to consume fluid at a rate of at least 60 ml / min, with the steam generator 30 itself consuming fluid at a rate of at least 35 ml / min. This not only ensures sufficient steam and garment care liquid enters the garment treatment drum 10, but also provides a clear visualization of the steam's moisture content by quantifying fluid consumption, offering excellent visibility and allowing users to easily understand and control the equipment's operating status. For example, when processing a cotton shirt, by observing the fluid consumption displayed on the control panel, the user can roughly determine whether the current steam moisture content is suitable for the shirt's processing needs. If the user finds the fluid consumption to be low, it may mean the steam moisture content is low. In this case, the user can adjust the program or parameters appropriately based on experience or equipment prompts to increase the steam moisture content, thereby achieving better wrinkle removal and conditioning effects on the shirt. This visual design allows users to clearly understand the equipment's working status, enabling them to operate the equipment more precisely according to the different materials and processing needs of the clothing, achieving the best clothing processing results.

[0085] In this embodiment, the fluid supply device 40 is connected to the steam generator 30 and configured to supply fluid to the steam generator 30. It is also connected to the second supply channel 2301 and configured to supply fluid to the dispensing device 20. The fluid supply device 40 can supply fluid to both the steam generator 30 and the dispensing device 20 simultaneously, or it can supply fluid to either the steam generator 30 or the dispensing device 20 individually. The fluid provided by the fluid supply device 40 is a liquid fabric softener, which may include an aqueous solution or functional agents, including but not limited to detergents, fabric softeners, and fragrances. During the drying process, an appropriate amount of fabric softener enters the garment processing drum 10 along with the steam, making the clothes softer and more fragrant after drying, and further improving the wrinkle-removing effect.

[0086] In some embodiments, the garment processing equipment also includes a fluid consumption detection device configured to monitor the fluid consumption of the fluid supply device 40 in real time, providing users with intuitive information so as to better control the equipment's operating status and garment processing effect.

[0087] In some embodiments, the fluid supply device 40 includes a liquid supply box 41, which is generally shaped like a container with a certain volume. The liquid supply box 41 is made of a corrosion-resistant and non-deformable material to ensure long-term stable storage and delivery of liquid. The internal space of the liquid supply box 41 is configured to hold liquids such as laundry detergent.

[0088] The liquid supply box 41 has a first liquid outlet 4101 and a second liquid outlet 4102. The first liquid outlet 4101 is connected to the liquid inlet of the steam generator 30, allowing liquid in the liquid supply box 41 to flow into the steam generator 30. When the steam generator 30 needs to generate steam, liquid is supplied from the liquid supply box 41 through the first liquid outlet 4101. For example, during equipment operation, if the steam generator 30 needs to generate a certain amount of steam to treat clothing according to a preset program or user settings, the liquid in the liquid supply box 41 will be replenished to the steam generator 30 through the first liquid outlet 4101 to ensure continuous steam generation.

[0089] The second outlet 4102 connects to the second supply channel 2301 and is configured to deliver the liquid in the supply box 41 to the dispensing device 20. When the device is treating clothes, the liquid enters the second supply channel 2301 from the supply box 41 through the second outlet 4102, and then mixes with the steam from the steam generator 30 in the dispensing device 20 to form a vapor-liquid mixture before being dispensed into the clothes treatment cylinder 10. This ensures that the clothes care liquid can fully combine with the steam to treat the clothes, achieving better clothes treatment results, such as wrinkle removal, softening, and fragrance enhancement.

[0090] The fluid consumption detection device in this embodiment includes a liquid level sensor and a control board. The liquid level sensor is a key component of the device, primarily configured to detect the liquid level in the supply box 41 in real time. The liquid level sensor converts changes in liquid level into electrical signals. For example, common liquid level sensors may operate based on capacitive or float principles. Taking a capacitive liquid level sensor as an example, when the liquid level rises or falls, the capacitance value inside the sensor changes accordingly, and this change has a specific functional relationship with the liquid level. The liquid level sensor converts this capacitance change into an electrical signal output, thereby reflecting the liquid level in the supply box 41 in real time.

[0091] The control board is electrically connected to the liquid level sensor and is configured to receive, process, calculate, and analyze the electrical signals transmitted by the liquid level sensor. The control board acquires signals from the liquid level sensor per unit time (e.g., per minute) and then calculates the liquid consumption in the supply box 41 based on these signals. The specific calculation method is based on the following formula: the liquid consumption P in the supply box 41 satisfies P=(H1-H2)*S. Where (H1-H2) represents the difference in liquid level height in the supply box 41 per unit time, which is obtained by the difference in liquid level height detected by the liquid level sensor before and after a unit time; S represents the cross-sectional area of ​​the supply box 41 in the height direction. For example, if in a certain minute, the liquid level sensor detects that the liquid level in the supply box 41 drops from H1=8cm to H2=7.4cm, and the cross-sectional area of ​​the supply box 41 in the height direction is S=100cm². 2Therefore, according to the formula, the liquid consumption in the liquid supply box 41 within this minute is P = (8 - 7.4) * 100 = 60 cm³. 3 (i.e., 60ml). Through this precise calculation method, the control board can calculate the liquid consumption in the liquid supply box 41 in real time and accurately, and transmit this information to the equipment's control system, which can then display it to the user on the control panel or configure it for automatic adjustment, thus enhancing the equipment's intelligence and visibility.

[0092] In other embodiments, the fluid supply device 40 includes a liquid supply box 41, a first liquid supply path 42, and a second liquid supply path 43. The liquid supply box 41 has a first liquid outlet 4101 and a second liquid outlet 4102. The liquid supply box 41 is a container for storing liquids (such as laundry detergent).

[0093] The first liquid supply path 42 connects the first liquid outlet 4101 and the liquid inlet of the steam generator 30, and is configured to transport the liquid in the liquid supply box 41 to the steam generator 30 to provide raw materials for steam generation. For example, when the steam generator 30 needs to work to generate steam, the liquid flows from the liquid supply box 41 to the steam generator 30 through the first liquid supply path 42 to ensure continuous steam generation.

[0094] The second liquid supply path 43 connects the second liquid outlet 4102 and the second supply channel 2301. It is configured to transport the liquid in the liquid supply box 41 to the second supply channel 2301, and then mix it with steam in the dispensing device 20 to form a vapor-liquid mixture, which is then dispensed into the clothing treatment cylinder 10 to achieve clothing care, such as wrinkle removal, softening, and fragrance enhancement.

[0095] The first liquid supply line 42 and the second liquid supply line 43 may include water pipes and various valves installed on the water pipes.

[0096] In this embodiment, the fluid consumption detection device is installed in the first liquid supply path 42 and the second liquid supply path 43. In this way, the flow of liquid in the two liquid supply paths can be detected separately, thereby accurately calculating the amount of liquid consumed in the liquid supply box 41.

[0097] For example, the fluid consumption detection device includes a flow meter configured to detect the flow rate through the first supply path 42 and the second supply path 43. For instance, if the flow rate detected by the first supply path 42 is 35 ml / min and the flow rate detected by the second supply path 43 is 25 ml / min, then the total fluid consumed in the supply box 41 is the sum of the flow rates of the two supply paths, i.e., 60 ml / min. In this way, the consumption rate and total amount of liquid in the supply box 41 can be obtained in real time and accurately, providing a basis for monitoring the equipment's operating status and for user operation.

[0098] When using garment processing equipment, users can understand the current operating status of the equipment by observing the fluid consumption monitored by the fluid consumption detection device. For example, when processing a silk garment, a lower steam moisture content may be required. Users can then check whether the current fluid consumption meets the requirements. If the fluid consumption is too high, it may mean that the steam moisture content is too high. Users can adjust relevant parameters appropriately through the equipment's control system, such as reducing the power of the steam generator 30, to protect the silk garment from damage while still achieving a certain conditioning effect, such as removing odors.

[0099] As shown in Figures 2 and 9, in some embodiments, the clothing processing device further includes a front support 50, which has a clothing inlet 101. The clothing processing cylinder 10 is installed at the clothing inlet 101 of the front support 50, and the inner cavity of the clothing processing cylinder 10 is connected to the clothing inlet 101. The user can put the clothing to be processed into the clothing processing cylinder 10 through the clothing inlet 101.

[0100] The front support 50 also has a drainage channel 501, which is located on one side of the clothing inlet 101 and extends downwards towards the bottom. In this embodiment, the drainage channel 501 is a crucial guarantee for the safe operation of the equipment. During operation, when steam is discharged from the pressure relief port 2401 of the dispensing device 20, the steam quickly condenses into liquid upon cooling. Guided by the drainage channel 501, this liquid flows along a specific preset trajectory. For example, the direction of the drainage channel 501 avoids critical wiring and electrical components inside the equipment, such as motors and control circuit boards, effectively preventing the risk of short circuits, corrosion, and other malfunctions caused by liquid contact, thus greatly improving the reliability and service life of the equipment.

[0101] The dispensing device 20 in this embodiment has a pressure relief port 2401, which is connected to the injection port 2034. The pressure relief port 2401 has two connection methods. First, when the pressure relief port 2401 is connected to the drainage channel 501, in the event of excessive internal pressure, steam will be discharged from the pressure relief port 2401 and enter the drainage channel 501. The steam rapidly condenses into liquid within the drainage channel 501 and flows along a predetermined trajectory within the drainage channel 501, preventing damage to the equipment. Second, the pressure relief port 2401 can also be connected to the inner cavity of the clothing processing drum 10, allowing excess steam to be discharged into the drum, ensuring the stability and safety of the clothing processing process.

[0102] In some embodiments, the front support 50 is formed with at least one guide plate 51 protruding along the front side direction of the front support 50, the guide plate 51 forming a flow channel 501. Exemplarily, the guide plate 51 may be a rib formed in the front support 50. The protruding design of the guide plate 51 can effectively guide the flow of liquid. For example, when there is only one guide plate 51, it will guide the vapor condensate discharged from the pressure relief port 2401 to flow in a specific direction, away from critical areas inside the equipment.

[0103] In some embodiments, the front support 50 has two protruding guide plates 51 along the front side of the front support 50, and the two guide plates 51 enclose a flow channel 501. This structure with two guide plates 51 can more accurately plan the flow trajectory of the liquid. The gap between the two guide plates 51 forms a channel with good sealing, so that the liquid can only flow from the pressure relief port 2401 to the bottom of the equipment along a predetermined path, which greatly avoids random splashing and leakage of liquid.

[0104] In some embodiments, the front support 50 has two drainage plates 51 protruding along the front side of the front support 50, and the two drainage plates 51 and the housing 100 enclose each other to form a drainage channel 501. In this case, the housing 100 and the drainage plates 51 together construct the drainage channel 501, further enhancing the sealing and stability of the drainage channel 501. The housing 100 not only prevents liquid from overflowing to the outside of the equipment, but also, together with the drainage plates 51, reliably guides the liquid to a designated location, ensuring that the internal wiring and electrical components of the equipment are completely protected from the threat of liquid. The drainage channel 501 is typically made of a smooth material, and whether it is formed by a single drainage plate 51, two drainage plates 51 individually, or enclosed together with the housing 100, its purpose is to ensure smooth liquid flow.

[0105] As shown in Figures 2, 3 and 9, in some embodiments, the garment processing device further includes a liquid receiving section located below the drainage channel 501 and configured to receive liquid flowing out of the drainage channel 501.

[0106] In some embodiments, the front support 50 has a liquid inlet 502 at one end near the base 60, and the liquid inlet 502 is located around the garment inlet 101, communicating with the liquid inlet of the liquid supply box 41. The function of the liquid inlet 502 is to inject garment care liquid to replenish the liquid supply box 41 with the required garment care liquid. Its design fully considers the convenience of operation, allowing users to easily and quickly add care liquid to the liquid supply box 41 through the liquid inlet 502, ensuring a sufficient supply of care liquid when the device is performing garment care.

[0107] In some embodiments, the bottom of the front support 50 is connected to the base 60, and the base 60 has a water receiving trough communicating with the drainage channel 501, which serves as a liquid receiving part. Exemplarily, the water receiving trough is located within the condensate drainage channel of the base 60. When the liquid condensed from steam flows from the drainage channel 501 onto the base 60, it passes through the through-holes on the base 60 into the heat exchange channel and finally flows into the water receiving trough. This design combines liquid collection with the condensate drainage system within the base 60, achieving not only effective liquid collection but also timely liquid discharge through the condensate drainage system, preventing liquid accumulation.

[0108] In other embodiments, the liquid supply box 41 is connected to the front support 50 and located below the dispensing device 20, the drainage channel 501 communicates with the liquid supply box 41, and the liquid supply box 41 is formed as a liquid receiving part.

[0109] For example, the front support 50 is provided with a liquid injection port 502 at one end near the base 60, and the liquid injection port 502 is connected to the liquid inlet of the liquid supply box 41. The liquid injection port 502 is configured to inject fabric care liquid into the liquid supply box 41 in order to replenish the liquid supply box 41 with the required fabric care liquid.

[0110] In this embodiment, liquid can flow from the drainage channel 501 through the through hole of the front support 50 into the injection port 502, and then finally flow into the liquid supply box 41 through the injection port 502. This design not only realizes the recycling of steam condensate, but also reduces the dependence on external water sources to a certain extent by replenishing the liquid in the liquid supply box 41, thereby improving resource utilization efficiency.

[0111] Please refer to Figures 5, 6, 7 and 8. In some embodiments, the dispensing device 20 includes a main body 21, a first connector 22 and a second connector 23.

[0112] The main body 21 is the core part of the dispensing device 20, and its interior is provided with a dispensing channel 201. The downstream part of the dispensing channel 201 forms a Venturi channel 203 with a jet nozzle 2034. The Venturi channel 203 is a special fluid acceleration structure that utilizes the changes in fluid velocity and pressure at different pipe diameters to achieve efficient mixing and jetting of the dynamic fluid and liquid.

[0113] In the fluid flow direction, the Venturi channel 203 consists of a first flow channel section 2031, a throat section 2032, and a second flow channel section 2033 connected in sequence. The first connector 22 is connected to the main body 21, and the connection method can be welding, integral molding, etc. The first connector 22 has a first supply flow channel 2201, which communicates with the delivery flow channel 201. The first supply flow channel 2201 is configured to supply the motive fluid into the delivery flow channel 201. The inner diameter of the first supply flow channel 2201 is defined as φ1, the inner diameter of the first flow channel section 2031 as φ2, and the inner diameter of the throat section 2032 as φ3, where φ3 < φ2 ≤ φ1. For example, φ3 satisfies 1 mm ≤ φ3 ≤ 2 mm. The second flow channel section 2033 is located after the throat section 2032, and its function is to guide the fluid, after being accelerated and mixed by the throat section 2032, to flow stably to the injection port 2034.

[0114] The Venturi channel 203 operates as follows: When a motive fluid (e.g., steam) enters the inlet channel 201 from the first connector 22 and flows into the Venturi channel 203, the fluid begins to converge initially and its velocity increases as it flows through the first channel section 2031. When it reaches the throat section 2032, the inner diameter suddenly narrows to φ3, and according to Bernoulli's principle, the fluid velocity increases sharply, the pressure drops significantly, and a low-pressure region is formed. This low-pressure region provides the basic conditions for the subsequent intake and mixing of the liquid. Afterward, the fluid enters the second channel section 2033, where the pipe diameter gradually increases, the velocity decreases, and the pressure gradually recovers, ultimately being ejected from the nozzle 2034 with higher kinetic energy and a better mixing effect.

[0115] For example, φ1 satisfies 5mm≤φ1≤7mm. This inner diameter range is determined based on data from multiple experiments. On the one hand, a sufficiently large inner diameter φ1 ensures that the motive fluid (such as steam) can flow into the delivery channel 201 at a large flow rate and appropriate speed, providing sufficient motive fluid for the subsequent Venturi effect and avoiding insufficient flow due to an excessively small inner diameter, which would affect the subsequent mixing and spraying effects. On the other hand, limiting the inner diameter size can prevent excessive pressure inside the equipment due to excessive flow, ensuring the safety and stability of the equipment operation.

[0116] In this embodiment, the second connector 23 is also connected to the main body 21, and the connection method can be welding, integral molding, etc. The second connector 23 has a second supply channel 2301 that communicates with the Venturi channel 203. The second supply channel 2301 is configured to allow liquid (such as laundry detergent) to flow into the dispensing channel 201. Under the action of the Venturi channel 203, due to the pressure reduction in the throat section 2032, a pressure difference is formed at the connection between the second supply channel 2301 and the Venturi channel 203, thereby drawing the liquid in the second supply channel 2301 into the Venturi channel 203 and mixing it thoroughly with the kinetic fluid.

[0117] The inner diameter of the second supply channel 2301 is φ4, and for example, φ4 satisfies φ2<φ4≤φ1.

[0118] This inner diameter design ensures that liquids (such as laundry detergents) can enter the Venturi channel 203 at an appropriate flow rate. When φ4 is within the range of φ2<φ4≤φ1, it ensures that the liquid can be effectively drawn into the low-pressure region of the Venturi channel 203, without causing uncontrolled liquid flow due to an excessively large inner diameter, or restricting the liquid supply due to an excessively small inner diameter, thus affecting the mixing effect with the kinetic fluid.

[0119] In this embodiment, the injection port 2034 is located downstream of the Venturi channel 203 and is the final outlet for the mixed fluid. Its diameter is φ5, and for example, φ5 satisfies φ5≥2*φ3.

[0120] This nozzle design enables better spraying results. The larger nozzle 2034 with a diameter of φ5 allows the mixed fluid to be sprayed into the garment treatment cylinder 10 at a relatively low speed and with a larger coverage area after leaving the Venturi channel 203. This avoids excessively high spray speeds caused by a small nozzle, which could lead to uneven spraying or excessive localized impact on the garments. At the same time, it ensures that the fully mixed kinetic fluid and liquid can evenly cover the surface of the garments, improving the garment treatment effect.

[0121] In some embodiments, the main body 21 includes a housing 211 and a core 212.

[0122] The housing 211 is an important component of the main body 21, and includes a first housing 2111 and a second housing 2112. The first housing 2111 has an opening slot 2102, which facilitates the installation and assembly of the core 212. The second housing 2112 is connected to the first housing 2111, and the second housing 2112 closes the opening of the opening slot 2102 of the first housing 2111, thereby defining the mounting cavity 2101. Exemplarily, the second housing 2112 is connected to the first housing 2111 by a threaded connection.

[0123] This split-shell design 211 not only facilitates manufacturing and assembly but also allows for maintenance and replacement of the internal core 212. Furthermore, the outer surface of the second shell 2112, away from the first shell 2111, has a diffuser 2103 communicating with the injection port 2034. The diffuser 2103 diffuses the mixed fluid ejected from the injection port 2034, allowing the mixed fluid to disperse more evenly after leaving the injection port 2034, further increasing the fluid distribution within the garment treatment drum 10 and ensuring more uniform coverage of the garments.

[0124] The core 212 is housed in the mounting cavity 2101, and a Venturi channel 203 is formed within the core 212. The Venturi channel 203 is a key structure for achieving efficient mixing and jetting in the dispensing device 20 of this embodiment. It utilizes the changes in flow velocity and pressure of the fluid at different pipe diameters to achieve efficient mixing and jetting of the kinetic fluid and the liquid.

[0125] To ensure the sealing of the dispensing device 20, in one embodiment, a first seal 213 is provided between the core 212 and the first shell 2111, and a second seal 214 is provided between the second shell 2112 and the first shell 2111. The seal can be in the form of a sealing ring. The first seal 213 prevents the leakage of kinetic fluid and liquid from the gap between the core 212 and the first shell 2111, ensuring that the fluid flows only within a preset flow channel, avoiding energy loss due to leakage and potential damage to other components of the device. The second seal 214 ensures a tight connection between the first shell 2111 and the second shell 2112, preventing external environmental factors (such as dust, moisture, etc.) from entering the mounting cavity 2101, thereby ensuring the cleanliness and stable operation of the dispensing device 20, and improving the reliability and safety of the device.

[0126] In some embodiments, the dispensing channel 201 extends along the length of the core 212, and the wall of the core 212 is provided with a suction channel 202 communicating with the Venturi channel 203. The suction channel 202 plays a key role in the dispensing device 20. Exemplarily, the suction channel 202 communicates with the throat section 2032 or the second channel section 2033, and the suction channel 202 also communicates with the second supply channel 2301, configured to draw in liquid. When the motive fluid flows within the Venturi channel 203, especially when a low-pressure region is formed in the throat section 2032, the suction channel 202 communicates with the throat section 2032 or the second channel section 2033, drawing the liquid in the second supply channel 2301 into the Venturi channel 203, thereby achieving mixing of the liquid and the motive fluid.

[0127] Furthermore, the inner diameter of the suction channel 202 is defined as φ6, wherein the ratio of the inner diameter φ3 of the throat section 2032 to the inner diameter φ6 of the suction channel 202 satisfies: 1≤φ3 / φ6≤3. This ratio range is carefully designed based on fluid dynamics principles and has a profound impact on the fluid flow characteristics between the suction channel 202 and the throat section 2032. Specifically, a smaller ratio means that the suction channel 202 is relatively coarse, allowing a larger flow rate of liquid to enter the Venturi channel 203, thereby increasing the suction speed and total volume of liquid. This is particularly advantageous when a large amount of liquid needs to be mixed with the motive fluid, such as when processing a large volume of clothing or when a high concentration of care solution is required. In this case, the value of φ3 / φ6 can be set closer to 1. Conversely, a larger ratio means that the suction channel 202 is relatively narrow, and the liquid suction flow rate will decrease accordingly. This is suitable for scenarios where the liquid suction volume requirement is lower, such as for certain delicate clothing processing procedures that are sensitive to liquid dosage. In this case, the value of φ3 / φ6 can be set closer to 3 to achieve finer flow control. By adjusting this ratio, the dispensing device 20 can flexibly adjust the liquid suction flow rate according to different clothing processing needs, ensuring that the mixing effect of the liquid and the motive fluid reaches the optimal state.

[0128] In some embodiments, the main body 21 has a pressure relief port 2401 communicating with the dispensing channel 201, and the main body 21 is connected to an exhaust valve 24, which controls the opening and closing of the pressure relief port 2401. When the internal pressure of the dispensing device 20 is too high, the excess pressure can be discharged through the pressure relief port 2401, avoiding damage to the device due to excessive pressure.

[0129] Furthermore, the delivery channel 201 also includes a connecting channel 204 that connects the first supply channel 2201 and the Venturi channel 203, and the pressure relief port 2401 is connected to the connecting channel 204. This design ensures that if an abnormal pressure occurs when the power fluid enters the connecting channel 204 from the first supply channel 2201, the pressure can be released in a timely manner through the pressure relief port 2401 and the exhaust valve 24, thus ensuring the safety and stability of the device operation.

[0130] The above are merely preferred embodiments of this application and are not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
