[0051] Please refer to Figures 1 to 8 The laundry treatment device provided by the embodiments of the present application can increase the water content of steam and improve the ironing effect, and has good visual effect.

[0052] The laundry treatment device of the embodiments can be a clothes dryer, a washing machine, a washing and drying integrated machine, etc., and the laundry treatment device of the embodiments will be described as a clothes dryer in the following.

[0053] The laundry treatment device of the embodiments includes a housing 100, a laundry treatment drum 10, a dispensing device 20, a steam generator 30, and a fluid supply device 40.

[0054] The housing 100 is generally hexahedral, commonly cuboid, which is convenient for placing and using. The housing 100 can be made of engineering plastic or metal material, which has good insulation performance and strong impact resistance. A control panel for user operation is arranged on the front surface of the housing 100, which integrates a touch display screen and multiple operation buttons. The touch display screen has an intuitive and convenient operation interface, and the user can easily select various laundry treatment programs, such as regular drying, steam care, fast drying, etc., through the touch screen to meet different laundry material and treatment requirements. The multiple operation buttons can be used as an auxiliary operation mode, and the user can start, pause, stop the program, or make other related settings, such as adjusting the drying time, temperature, etc., by pressing these buttons.

[0055] The laundry treatment drum 10 of the present embodiment is installed in the housing 100 and can be made of stainless steel. Stainless steel has high strength and corrosion resistance, and can withstand the strong centrifugal force generated by high-speed rotation during the laundry treatment process, ensuring that the laundry treatment drum 10 will not deform or be damaged due to stress during long-term use, thereby ensuring the stability and reliability of the equipment. The laundry treatment drum 10 is generally hollow and cylindrical in shape, and its internal space can be reasonably arranged according to the actual needs of the laundry treatment to accommodate different volumes and types of laundry, such as large bed sheets, comforters, or small items such as shoes.

[0056] During the laundry treatment process, the laundry treatment drum 10 can rotate, and when the laundry treatment drum 10 rotates, the laundry will move from the lower side to the upper side with the rotation of the drum wall, and then fall from the upper side to the lower side under the action of gravity, and so on. The laundry is fully dispersed, beaten, and changed in posture under the combined action of the rotation of the laundry treatment drum 10 and gravity. This movement mode allows the laundry to be evenly distributed in the drum, thereby ensuring that all parts of the laundry are evenly heated and dried, avoiding local overheating or uneven drying, greatly improving the drying efficiency and effect, and also helping to reduce wrinkles in the laundry, making the laundry flatter after drying.

[0057] By way of example, the laundry treatment device further comprises a motor, and the laundry treatment drum 10 is driven by the motor through a belt. The motor serves as a power source and transmits power to the laundry treatment drum 10 through the belt to drive the laundry treatment drum 10 to rotate at a set speed and direction. This transmission mode has the advantages of simple structure, stable transmission, and low noise, and can ensure that the laundry treatment drum 10 maintains a stable operating state during rotation.

[0058] In an embodiment, the laundry treatment device comprises a circulating air duct, the rear side of the laundry treatment drum 10 has an air inlet, the front side of the laundry treatment drum 10 has an air outlet, and the circulating air duct communicates with the air inlet and the air outlet. The circulating air duct is used to provide circulating airflow to the inner cavity of the laundry treatment drum 10. The airflow of the circulating air duct can enter the inner cavity of the laundry treatment drum 10 through the air inlet, and the airflow in the laundry treatment drum 10 enters the circulating air duct through the air outlet. The airflow can circulate between the circulating air duct and the laundry treatment drum 10.

[0059] Further, the laundry treatment device further comprises a base 60, which is arranged below the laundry treatment drum 10, and the base 60 forms a heat exchange channel, which is part of the circulating air duct.

[0060] The laundry treatment device further comprises a heat exchange assembly located in the heat exchange channel, the heat exchange assembly being configured to exchange heat with the air flow in the heat exchange channel, thereby dehumidifying and heating. The humid and hot air flow in the laundry treatment drum 10 enters the heat exchange channel and is converted into a dry and hot air flow after heat and mass exchange with the heat exchange assembly, and the dry and hot air flow is returned to the laundry treatment drum 10 through the air inlet.

[0061] Exemplarily, the heat exchange assembly comprises a condenser and an evaporator, and the laundry treatment device further comprises a compressor and a throttling device, the compressor, the condenser, the throttling device and the evaporator are connected by pipelines to form a heat pump system, and a refrigerant can circulate in the heat pump system. The air flow in the circulating air duct exchanges heat with the refrigerant in the evaporator and the condenser to form a dry and hot air flow. The evaporator is configured to cool and dehumidify the humid and hot air flow from the laundry treatment drum 10 to form a dry and cold air flow; and the condenser is configured to heat the dry and cold air flow into a dry and hot air flow to return to the laundry treatment drum 10.

[0062] The working principle of the heat pump system is as follows: the compressor sucks in low-pressure gaseous refrigerant and compresses it into high-pressure refrigerant which is discharged; the high-pressure refrigerant discharged enters the condenser, and the refrigerant in the condenser transfers heat to the air flow to condense into high-pressure liquid; the high-pressure liquid refrigerant flows through the throttling device to be throttled and decompressed, and then becomes a low-pressure and low-temperature gas-liquid two-phase mixture which enters the evaporator; the refrigerant in the evaporator absorbs heat from the air flow to become low-pressure gaseous refrigerant; the low-pressure gaseous refrigerant is sucked into the compressor again; and the cycle is repeated to realize heat exchange. That is, the evaporator is configured to cool and dehumidify the humid and hot air flow from the laundry treatment drum 10 to form a dry and cold air flow, and the condenser is configured to heat the dry and cold air flow into a dry and hot air flow to return to the laundry treatment drum 10. The dry and hot air flow returned to the laundry treatment drum 10 contacts the damp clothes again to form a humid and hot air flow again, thereby completing a drying cycle. By repeatedly operating the drying cycle, the circulating air flow is continuously provided to the laundry treatment drum 10 to dry the clothes.

[0063] Exemplarily, the evaporator and the condenser can both be finned tube heat exchangers.

[0064] Exemplarily, the throttling device includes but is not limited to an electronic expansion valve and the like.

[0065] In an embodiment, the laundry treatment device comprises a fan configured to drive the air flow. Exemplarily, the fan is located in the heat exchange channel. In the process of drying the clothes, the fan is configured to drive the air flow flowing through the clothes to sequentially flow through the evaporator and the condenser, and then blow to the clothes to form a circulating air flow.

[0066] The delivery device 20 of the embodiment is in communication with the laundry treatment drum 10, and the delivery device 20 has a first supply flow channel 2201 and a second supply flow channel 2301. The delivery device 20 is configured to deliver the fluid from the first supply flow channel 2201 and the fluid from the second supply flow channel 2301 to the laundry treatment drum 10 in the form of a vapor-liquid mixture. The delivery device 20 can adopt various structural forms, such as a spray head or a powered pump structure.

[0067] When the spray head structure is adopted, the steam and the garment care liquid can be uniformly sprayed in the form of mist onto the garments in the laundry treatment drum 10 after being mixed in the spray head. This mist spraying mode can enable the vapor-liquid mixture to fully cover the surface of the garments, ensuring that the steam and the garment care liquid can be contacted by each part of the garments, thereby achieving better treatment effect. For example, when the steam care program is performed, the spray head can uniformly spray the hot steam and the garment care liquid containing a softener onto the garments after being mixed, and the heat and humidity of the hot steam can soften the fibers of the garments, while the softener can further make the fibers soft, and the two work together to significantly improve the wrinkle removal effect and softness of the garments.

[0068] When the powered pump structure is adopted, a power source (such as electric energy or other energy) provides power to change the flow rate and / or flow direction of the steam, so that the steam and the garment care liquid can be better mixed and enter the laundry treatment drum 10 in the form of a vapor-liquid mixture. The powered pump can control the mixing ratio of the steam and the garment care liquid and the delivery speed and direction according to the preset program or the user's settings, thereby achieving more intelligent garment treatment. For example, for some more delicate garment materials, such as silk, the mixing ratio of the steam and the garment care liquid and the delivery speed can be adjusted by the powered pump structure to avoid damage to the garments, while achieving good care effect.

[0069] The steam generator 30 of the embodiment has a steam outlet 301 in communication with the first supply flow channel 2201. The steam generator 30 can generate steam, which can include hot steam and cold steam. The hot steam is a high-temperature vapor state generated after being heated by the steam generator 30, and the temperature is higher than 100°C. The cold steam is a mist state of a fluid after being dispersed, and the temperature is normal temperature (20-40°C) or low temperature (lower than 20°C).

[0070] In addition, the steam generator 30 is also configured to provide driving force for the dispensing device 20. When the dispensing device 20 is in a spraying operation, the steam generator 30 can cause the fluid supply device 40 to consume fluid at a speed of at least 60 ml / min, and the steam generator 30 itself consumes fluid at a speed of at least 35 ml / min. In this way, not only can sufficient steam and garment care liquid be ensured to enter the garment treatment drum 10, but also the water content of the steam can be intuitively reflected by quantifying the fluid consumption, which has a good visualization effect, and the user can understand and control the operation state of the equipment. For example, when the user processes a cotton shirt, by observing the fluid consumption displayed on the control panel, the user can roughly judge whether the current water content of the steam is suitable for the processing needs of the shirt. If the user finds that the fluid consumption is low, it may mean that the water content of the steam is low, at which time the user can adjust the program or parameters as needed according to experience or prompts of the equipment to increase the water content of the steam, so as to better achieve the wrinkle removal and care effect of the shirt. This visual design enables the user to more clearly understand the working state of the equipment, so that the user can more accurately operate the equipment according to the material and processing needs of different garments to achieve the best garment processing effect.

[0071] The fluid supply device 40 of the embodiment is in communication with the steam generator 30 for supplying fluid to the steam generator 30, and is also in communication with the second supply channel 2301 for supplying fluid to the dispensing device 20. The fluid supply device 40 can supply fluid to the steam generator 30 and the dispensing device 20 simultaneously, or can supply fluid to the steam generator 30 or the dispensing device 20 separately. The fluid supplied by the fluid supply device 40 is liquid garment care liquid, which can include water or functional agents, including but not limited to detergents, softeners, fragrance enhancers, etc. When the garment is being dried, an appropriate amount of garment care liquid enters the garment treatment drum 10 together with the steam, which can make the garment more soft and fragrant after drying, and can further improve the wrinkle removal effect.

[0072] Further, the garment treatment equipment also includes a fluid consumption detection device for real-time monitoring of the fluid consumption of the fluid supply device 40, to provide intuitive information for the user to better control the equipment operation state and garment treatment effect.

[0073] In one embodiment, the fluid supply device 40 includes a liquid supply box 41, which is generally in the shape of a container with a certain volume, and the material thereof can be selected from corrosion-resistant and non-deformable materials to ensure long-term stable storage and delivery of liquid. The internal space of the liquid supply box 41 is used to contain liquid such as garment care liquid.

[0074] 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, so that the liquid in the liquid supply box 41 can flow into the steam generator 30. When the steam generator 30 needs to generate steam, the liquid in the liquid supply box 41 is supplied to the steam generator 30 through the first liquid outlet 4101. For example, during the operation of the device, the steam generator 30 needs to generate a certain amount of steam according to the preset program or user settings to treat the clothes. At this time, the liquid in the liquid supply box 41 will be timely supplemented to the steam generator 30 through the first liquid outlet 4101, ensuring the continuous generation of steam.

[0075] The second liquid outlet 4102 is connected to the second supply flow channel 2301, and is used to transport the liquid in the liquid supply box 41 to the dispensing device 20. When the device is treating clothes, the liquid in the liquid supply box 41 enters the second supply flow channel 2301 through the second liquid outlet 4102, and then mixes with the steam from the steam generator 30 in the dispensing device 20 to form a steam-liquid mixture before being dispensed into the clothes treatment drum 10. In this way, it is ensured that the clothes care liquid can be fully combined with the steam to act on the clothes together, achieving better clothes treatment effects such as wrinkle removal, softening, and fragrance enhancement.

[0076] The fluid consumption detection device of the embodiment includes a liquid level sensor and a control board. The liquid level sensor is one of the key components of the fluid consumption detection device, and is mainly used to detect the liquid level height in the liquid supply box 41 in real time. The liquid level sensor converts the change of the liquid level into an electrical signal. For example, a common liquid level sensor may work based on the principle of capacitance type or float type. Taking the capacitance type liquid level sensor as an example, when the liquid level rises or falls, the capacitance value inside the sensor will change accordingly, and this change has a specific functional relationship with the liquid level height. The liquid level sensor converts this capacitance change into an electrical signal output, thereby reflecting the high and low of the liquid level in the liquid supply box 41 in real time.

[0077] The control board is electrically connected with the liquid level sensor, and is used to receive, process, calculate and analyze the electrical signals transmitted by the liquid level sensor. The control board acquires the signals of the liquid level sensor in a unit time (such as every minute), and then calculates the liquid consumption in the liquid supply box 41 according to these signals. The specific calculation method is based on the following formula: the liquid consumption P in the liquid supply box 41 satisfies P=(H1-H2)*S. Wherein, (H1-H2) represents the liquid level height difference of the liquid supply box 41 in a unit time, which is obtained by detecting the liquid level height difference before and after a unit time by the liquid level sensor; S represents the cross-sectional area of the liquid supply box 41 in the height direction. For example, if in a certain minute, the liquid level sensor detects that the liquid level of the liquid supply box 41 drops from H1=8cm to H2=7.4cm, and the cross-sectional area S of the liquid supply box 41 in the height direction is 100cm 2Then, according to the formula, the liquid consumption P in the liquid supply box 41 in this minute is calculated as P = (8-7.4) * 100 = 60 cm (i.e. 60 ml). Through this accurate calculation, the control panel can calculate the liquid consumption in the liquid supply box 41 in real time and accurately, and transmit the information to the control system of the device, and then display the information to the user on the control panel, or used for automatic adjustment of the device, thereby enhancing the intelligent and visual degree of the device. 3 (That is, 60 ml). Through this accurate calculation, the control panel can calculate the liquid consumption in the liquid supply box 41 in real time and accurately, and transmit the information to the control system of the device, and then display the information to the user on the control panel, or used for automatic adjustment of the device, thereby enhancing the intelligent and visual degree of the device.

[0078] In another embodiment, the fluid supply device 40 includes a liquid supply box 41, a first liquid supply path 42 and a second liquid supply path 43, and 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 liquid (such as laundry care liquid, etc.).

[0079] The first liquid supply path 42 connects the first liquid outlet 4101 and the liquid inlet of the steam generator 30, and is used to transport the liquid in the liquid supply box 41 to the steam generator 30 to provide raw materials for the generation of steam. 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 the continuous generation of steam.

[0080] The second liquid supply path 43 connects the second liquid outlet 4102 and the second supply flow channel 2301, and is used to transport the liquid in the liquid supply box 41 to the second supply flow channel 2301, and then mix with the steam in the delivery device 20 to form a steam-liquid mixture and then delivered into the laundry treatment drum 10 to achieve care of the laundry, such as wrinkle removal, softening, fragrance enhancement, etc.

[0081] The first liquid supply path 42 and the second liquid supply path 43 can include a water pipe and various valves arranged on the water pipe.

[0082] The fluid consumption detection device of the present embodiment is arranged 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 respectively, so that the liquid consumption in the liquid supply box 41 can be accurately calculated.

[0083] For example, the fluid consumption detection device includes a flow meter for detecting the flow rate of the liquid flowing through the first liquid supply path 42 and the second liquid supply path 43. For example, the flow rate detected by the first liquid supply path 42 is 35 ml / min, and the flow rate detected by the second liquid supply path 43 is 25 ml / min, and then the total amount of fluid consumed in the liquid supply box 41 is the sum of the flow rates of the two liquid supply paths, i.e. 60 ml / min. In this way, the consumption rate and total amount of liquid in the liquid supply box 41 can be obtained in real time and accurately, which provides a basis for the operation state monitoring of the device and the user operation.

[0084] 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.

[0085] like Figure 2 and Figure 9 As shown, 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.

[0086] 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.

[0087] 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.

[0088] In one embodiment, the front support 50 is formed with at least one flow guide plate 51 protruding in the front direction of the front support 50, and the flow guide plate 51 forms a flow channel 501. Exemplarily, the flow guide plate 51 can be a rib plate formed on the front support 50. The protruding design of the flow guide plate 51 can effectively guide the flow of liquid. For example, when there is only one flow guide plate 51, it can guide the steam condensate discharged from the pressure relief port 2401 to flow in a specific direction, away from the critical areas inside the device.

[0089] In one embodiment, the front support 50 is formed with two flow guide plates 51 protruding in the front direction of the front support 50, and the two flow guide plates 51 form a flow channel 501. The structure of the two flow guide plates 51 enclosing each other can more accurately plan the flow trajectory of the liquid. The gap between the two flow guide plates 51 forms a channel with better sealing, so that the liquid can only flow from the pressure relief port 2401 to the bottom of the device along the predetermined path, greatly avoiding the random splashing and leakage of the liquid.

[0090] In one embodiment, the front support 50 is formed with two flow guide plates 51 protruding in the front direction of the front support 50, and the two flow guide plates 51 form a flow channel 501 with the shell 100. At this time, the shell 100 and the flow guide plates 51 jointly constitute the flow channel 501, further enhancing the sealing and stability of the flow channel 501. The shell 100 can not only prevent liquid from overflowing outside the device, but also, together with the flow guide plates 51, more reliably guide the liquid to the designated position, ensuring that the internal circuits and electrical components of the device are completely protected from the threat of liquid. The flow channel 501 is usually made of smooth material, whether it is formed by a single flow guide plate 51, two flow guide plates 51 alone, or jointly enclosed with the shell 100, all with the purpose of ensuring smooth flow of liquid.

[0091] As shown in Figure 2 , Figure 3 and Figure 9 , in some embodiments, the laundry treatment apparatus further includes a liquid receiving portion located below the flow channel 501 for receiving the liquid flowing out of the flow channel 501.

[0092] In one embodiment, the front support 50 is formed with at least one flow guide plate 51 protruding in the front direction of the front support 50, and the flow guide plate 51 forms a flow channel 501. Exemplarily, the flow guide plate 51 can be a rib plate formed on the front support 50. The protruding design of the flow guide plate 51 can effectively guide the flow of liquid. For example, when there is only one flow guide plate 51, it can guide the steam condensate discharged from the pressure relief port 2401 to flow in a specific direction, away from the critical areas inside the device.

[0093] In one embodiment, the bottom of the front support 50 is connected with the base 60, and the base 60 is formed with a water receiving groove in communication with the drainage channel 501, and the water receiving groove is formed as a liquid receiving part. Illustratively, the water receiving groove is located in the condensate drainage passage of the base 60, and when the liquid condensed from the steam flows from the drainage channel 501 to the base 60, it will pass through the through hole on the base 60 into the heat exchange passage, and finally flow into the water receiving groove. Such design can combine the liquid collection with the condensate drainage system in the base 60, not only realizing the effective collection of the liquid, but also timely discharging the liquid by using the condensate drainage system, avoiding the accumulation of the liquid.

[0094] In another embodiment, the liquid supply box 41 is connected to the front support 50 and located below the dispensing device 20, the drainage channel 501 is in communication with the liquid supply box 41, and the liquid supply box 41 is formed as a liquid receiving part.

[0095] Illustratively, the front support 50 is provided with a liquid injection port 502 at one end close to the base 60, and the liquid injection port 502 is in communication with the liquid inlet of the liquid supply box 41. The liquid injection port 502 is used to inject the laundry care liquid into the liquid supply box 41, so as to supplement the laundry care liquid required by the liquid supply box 41.

[0096] In this embodiment, the liquid can flow from the drainage channel 501 through the through hole of the front support 50 into the liquid injection port 502, and finally flow into the liquid supply box 41 through the liquid injection port 502. Such design not only realizes the recycling of the steam condensate liquid, but also reduces the dependence on external water source to a certain extent by supplementing the liquid in the liquid supply box 41, and improves the resource utilization efficiency.

[0097] Please refer to Figure 5 、 Figure 6 、 Figure 7 and Figure 8 In one embodiment, the dispensing device 20 comprises a main body 21, a first joint 22 and a second joint 23.

[0098] The main body 21 is the core part of the dispensing device 20, and the inside of the main body 21 is provided with a dispensing passage 201. The downstream part of the dispensing passage 201 forms a Venturi channel 203 with a jet port 2034. The Venturi channel 203 is a special fluid acceleration structure, which uses the flow rate and pressure changes of fluid at different pipe diameters to realize efficient mixing and injection of power fluid and liquid, so as to increase the water content of steam and improve the ironing effect.

[0099] In the direction of fluid flow, the Venturi channel 203 is composed of a first flow channel section 2031, a throat section 2032 and a second flow channel section 2033 connected in sequence. The first joint 22 is connected to the main body 21 in a manner such as welding, one-piece forming, etc. The first joint 22 has a first supply flow channel 2201 which is in communication with the delivery flow channel 201. The first supply flow channel 2201 is used for supplying power fluid to flow 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 is defined as φ2, the inner diameter of the throat section 2032 is defined as φ3, and φ3 < φ2 ≤ φ1. Exemplarily, φ3 satisfies 1mm ≤ φ3 ≤ 2mm. The second flow channel section 2033 is behind the throat section 2032, and its function is to guide the fluid after accelerated mixing in the throat section 2032 to flow stably to the injection port 2034.

[0100] The working principle of the Venturi channel 203 is as follows: when the power fluid (such as steam) enters the delivery flow channel 201 from the first joint 22 and flows to the Venturi channel 203, the fluid begins to preliminarily converge and its flow rate begins to accelerate when flowing through the first flow channel section 2031; when reaching the throat section 2032, the inner diameter suddenly shrinks to φ3, according to Bernoulli's principle, the flow rate of the fluid increases sharply, and the pressure drops significantly, forming a low-pressure area. This low-pressure area provides the basic conditions for the subsequent intake and mixing of liquid. Then, the fluid enters the second flow channel section 2033, the pipe diameter gradually increases, the flow rate decreases, and the pressure gradually recovers, and finally the fluid is sprayed from the injection port 2034 with high kinetic energy and mixing effect.

[0101] Exemplarily, φ1 satisfies 5mm ≤ φ1 ≤ 7mm. This inner diameter range is obtained through multiple test data, on the one hand, a large enough inner diameter φ1 ensures that the power fluid (such as steam) can flow into the delivery flow channel 201 with a large flow rate and a suitable speed, providing sufficient power fluid for the subsequent Venturi effect, avoiding insufficient flow rate due to too small inner diameter, affecting the subsequent mixing and spraying effect; on the other hand, limiting the size of the inner diameter can prevent the internal pressure of the equipment from being too high due to excessive flow rate, ensuring the safety and stability of the equipment operation.

[0102] The second joint 23 of the embodiment is also connected to the main body 21 in a manner such as welding, one-piece forming, etc. The second joint 23 is internally provided with a second supply flow channel 2301 which is in communication with the Venturi channel 203. The second supply flow channel 2301 is used for supplying liquid (such as laundry care liquid, etc.) to flow into the delivery flow channel 201. Under the action of the Venturi channel 203, due to the pressure drop in the throat section 2032, a pressure difference will be formed at the connection between the second supply flow channel 2301 and the Venturi channel 203, thereby sucking the liquid in the second supply flow channel 2301 into the Venturi channel 203 and fully mixing with the power fluid.

[0103] The inner diameter of the second supply flow channel 2301 is φ4, and φ4 satisfies φ2 < φ4 ≤ φ1.

[0104] Such an inner diameter design ensures that the liquid (such as a laundry care liquid) can enter the Venturi channel 203 at a suitable flow rate. When φ4 is in the range of φ2 < φ4 ≤ φ1, it can not only ensure that the liquid can be effectively sucked into the low-pressure area of the Venturi channel 203, but also can prevent the liquid flow from being out of control due to an excessively large inner diameter, or the supply of the liquid being limited due to an excessively small inner diameter, thereby affecting the mixing effect with the motive fluid.

[0105] The ejection port 2034 of the embodiment is located downstream of the Venturi channel 203, and is an outlet through which the mixed fluid is finally ejected. The diameter of the ejection port 2034 is φ5, and φ5 satisfies φ5 ≥ 2*φ3.

[0106] Such a diameter design can achieve a better ejection effect. The relatively large diameter φ5 of the ejection port 2034 enables the mixed fluid to be ejected into the laundry treatment drum 10 at a relatively low speed and a large coverage area after leaving the Venturi channel 203, thereby avoiding excessively high ejection speed caused by an excessively small diameter, which can result in uneven ejection or cause local excessive impact on the laundry, while ensuring that the mixed fluid of the motive fluid and the liquid can uniformly cover the surface of the laundry, thereby improving the effect of the laundry treatment.

[0107] In an embodiment, the main body 21 includes a shell 211 and a core 212.

[0108] The shell 211 is an important component of the main body 21, and includes a first shell 2111 and a second shell 2112. The first shell 2111 has an open slot 2102, which facilitates the installation and assembly of the core 212. The second shell 2112 is connected to the first shell 2111, and the second shell 2112 closes the opening of the open slot 2102 of the first shell 2111, thereby defining a mounting cavity 2101. Exemplarily, the second shell 2112 is connected to the first shell 2111 in a threaded connection.

[0109] Such a split-type shell 211 design not only facilitates manufacturing and assembly, but also facilitates maintenance and replacement of the internal core 212. Further, the second shell 2112 is formed away from the outer surface of the first shell 2111 to form a diffusion port 2103 that communicates with the ejection port 2034. The diffusion port 2103 can diffuse the mixed fluid ejected from the ejection port 2034 to some extent, so that the mixed fluid can be more uniformly dispersed after leaving the ejection port 2034, thereby further improving the distribution range of the fluid in the laundry treatment drum 10 and ensuring that the mixed fluid can more uniformly cover the laundry.

[0110] The core 212 is accommodated in the installation cavity 2101, and a Venturi channel 203 is formed in the core 212. The Venturi channel 203 is a key structure for the high-efficiency mixing and spraying of the delivery device 20 of the embodiment. It utilizes the flow rate and pressure changes of the fluid at different pipe diameters to achieve high-efficiency mixing and spraying of the power fluid and the liquid.

[0111] To ensure the sealing of the delivery device 20, in an embodiment, a first seal 213 is arranged between the core 212 and the first shell 2111, and a second seal 214 is arranged between the first shell 2111 and the second shell 2112. The seal can be in the form of a sealing ring. The first seal 213 prevents the power fluid and the liquid from leaking from the gap between the core 212 and the first shell 2111, ensures that the fluid only flows in the pre-set flow channel, and avoids energy loss and possible damage to other parts of the device due to leakage. The second seal 214 ensures the tight connection between the first shell 2111 and the second shell 2112, prevents external environmental factors (such as dust, moisture, etc.) from entering the installation cavity 2101, thereby ensuring the cleanliness and stable operation of the inside of the delivery device 20, and improving the reliability and safety of the device.

[0112] In an embodiment, the delivery flow channel 201 extends along the length direction of the core 212, and the wall of the core 212 is provided with a suction flow channel 202 communicating with the Venturi channel 203. The suction flow channel 202 plays a key role in the delivery device 20. Exemplarily, the suction flow channel 202 communicates with the throat section 2032 or the second flow channel section 2033, and the suction flow channel 202 also communicates with the second supply flow channel 2301 for suction of the liquid. When the power fluid flows in the Venturi channel 203, especially when the low-pressure area is formed in the throat section 2032, the suction flow channel 202 communicating with the throat section 2032 or the second flow channel section 2033 sucks the liquid in the second supply flow channel 2301 into the Venturi channel 203, achieving the mixing of the liquid and the power fluid.

[0113] Further, the inner diameter of the suction flow channel 202 is defined as φ6, and the ratio of the inner diameter φ3 of the throat section 2032 to the inner diameter φ6 of the suction flow channel 202 satisfies 1≤φ3 / φ6≤3. The ratio range is carefully set based on the principle of fluid mechanics and has a profound impact on the fluid flow characteristics between the suction flow channel 202 and the throat section 2032. Specifically, when the ratio is smaller, it means that the suction flow channel 202 is relatively thicker, which can allow a larger flow of liquid to flow into the Venturi channel 203, thereby increasing the suction speed and total amount of liquid, which is very advantageous in situations where a large amount of liquid needs to be mixed with the motive fluid, such as when a large amount of laundry is processed or a high concentration of care liquid is required to process the laundry. The value of φ3 / φ6 can be set closer to 1; when the ratio is larger, the suction flow channel 202 is relatively thinner, and the suction flow of liquid will be correspondingly reduced, which is suitable for some scenarios where the amount of liquid suction is required to be low, such as for some delicate laundry processing procedures that are sensitive to the amount of liquid, the value of φ3 / φ6 can be set closer to 3 to achieve more delicate flow control. By adjusting the ratio, the present dispensing device 20 can flexibly adjust the suction flow of liquid according to different laundry processing requirements, ensuring that the mixing effect of liquid and motive fluid reaches the best state.

[0114] In one embodiment, the main body 21 has a pressure relief port 2401 communicating with the dispensing flow channel 201, and the main body 21 is connected with an exhaust valve 24 that 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 to avoid damage to the device due to excessive pressure.

[0115] Further, the dispensing flow channel 201 further includes a connecting flow channel 204 communicating the first supply flow channel 2201 and the Venturi channel 203, and the pressure relief port 2401 communicates with the connecting flow channel 204. This design allows the pressure to be released in time through the pressure relief port 2401 and the exhaust valve 24 if an abnormal pressure occurs when the motive fluid enters the connecting flow channel 204 from the first supply flow channel 2201, ensuring the safety and stability of the device operation.

[0116] The above is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present application shall be included in the protection scope of the present application.
