The detailed description in the specific implementation should be understood as an explanation of the purpose of this application and should not be regarded as an undue limitation on this application.

In the embodiments of this application, the orientations or positional relationships of "up," "down," "front," "back," "left," and "right" are based on the orientations or positional relationships shown in the accompanying drawings. It should be understood that these orientational terms are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application. The application will be further described in detail below with reference to the accompanying drawings and specific embodiments. In addition, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0030] In this embodiment, "multiple" refers to a quantity including two or more. The unit "℃" refers to the temperature unit Celsius.

[0031] The clothing processing equipment provided in this application embodiment has no limited functionality. For example, the clothing processing equipment may have a drying function. The drying function can be used to dry clothes. The clothing processing equipment may also have a washing function, which is used to clean clothes. For example, the clothing processing equipment may be a dryer or a washer-dryer combo, etc.

[0032] Please see Figure 1 and Figure 2 The garment processing device may include a cylindrical assembly 1, the axis of which may extend horizontally or obliquely. The cylindrical assembly 1 has a garment processing chamber 1a for placing garments.

[0033] The extension of the axis of cylinder assembly 1 along the inclined direction means that the axis of cylinder assembly 1 is obliquely intersecting the horizontal direction.

[0034] In one embodiment, please refer to... Figure 1 and Figure 2 The cylinder assembly 1 includes a rotatable clothes container 11 with a forward-opening loading / unloading port. The clothes container 11 has a clothing handling chamber 1a and can be used to hold clothing or other loads. The user inserts or removes clothing from the clothes container 11 through the loading / unloading port from the front. The clothes container 11 can rotate; during rotation, it moves the clothing from bottom to top. Under the influence of gravity, the clothing falls from top to bottom. Thus, the clothing is dispersed, shaken, and its posture altered under the combined action of the clothes container 11 and gravity.

[0035] In some embodiments, the clothes container 11 may be generally hollow cylindrical.

[0036] In some embodiments, the cylindrical assembly 1 includes an outer tub, within which the clothes-holding tube 11 may be disposed. The outer tub may remain stationary. It is understood that the clothes-holding tube 11 may or may not have an outer tub.

[0037] In some embodiments, please refer to Figure 1 and Figure 2 The cylinder assembly 1 may consist only of the clothes-holding cylinder 11, without the aforementioned outer cylinder. In this embodiment, the clothes-holding cylinder 11 can be a single-cylinder structure. That is to say, the clothing processing device has only one cylinder, the clothes-holding cylinder 11.

[0038] In some embodiments, please refer to Figure 1 and Figure 2The garment handling equipment may include a front support 9. The axis of the tubular assembly 1 extends horizontally or obliquely, and the front support 9 may be located at the front end of the tubular assembly 1. The front support 9 can provide support for the tubular assembly 1.

[0039] The front support 9 may have a clothing inlet 9a, which is connected to the clothing processing chamber 1a. Taking the clothing container 11 as a single-tube structure as an example, the clothing container 11 may be connected to the front support 9 through a dynamic seal, and the clothing inlet 9a may be connected to the loading and unloading port.

[0040] In some embodiments, the garment processing device includes a housing, a cylindrical assembly 1 and a front support 9, both disposed within the housing, and the housing has an opening communicating with the garment processing chamber 1a of the cylindrical assembly 1.

[0041] In some embodiments, the housing may be approximately hexahedral in shape, such as a cube or a cuboid.

[0042] In some embodiments, the garment handling device includes a door for selectively opening or closing an opening in the housing.

[0043] Please see Figure 1 and Figure 2 The garment processing equipment includes a garment processing chamber 1a, a steam generator 4, and a fluid supply unit. The fluid supply unit includes a liquid storage box 5, a first liquid supply line 3, and a second liquid supply line 6.

[0044] Please see Figure 6 and Figure 7 The liquid storage box 5 has a first outlet 5a and a second outlet 5b. The liquid storage box 5 can be used to hold laundry detergent. Both the first outlet 5a and the second outlet 5b are used to discharge the laundry detergent from the liquid storage box 5.

[0045] Please see Figure 1 and Figure 3 The steam generator 4 has a liquid inlet 4b and a steam outlet 4a. The steam discharged from the steam outlet 4a enters the clothing processing chamber 1a. The liquid inlet 4b is used to introduce liquid into the steam generator 4, the steam generator 4 is used to generate steam, and the steam outlet 4a is used to discharge steam.

[0046] The first liquid supply circuit 3 connects to the first liquid outlet 5a and delivers fluid to the garment processing chamber 1a. The first liquid supply circuit 3 introduces the garment care liquid from the liquid storage box 5 into the garment processing chamber.

[0047] The second liquid supply circuit 6 connects the second liquid outlet 5b and the liquid inlet 4b. The second liquid supply circuit 6 introduces the laundry care liquid in the liquid storage box 5 into the steam generator 4.

[0048] It is understandable that both gaseous vapor and liquid laundry detergent are fluids.

[0049] In other words, both the steam generator 4 and the first liquid supply line 3 are connected to the liquid storage box 5, and both the steam generator 4 and the first liquid supply line 3 draw liquid from the liquid storage box 5.

[0050] The garment processing device provided in this application embodiment has a first liquid supply line 3 that delivers garment care liquid from the storage box 5 to the garment processing chamber 1a, and a second liquid supply line 6 that delivers garment care liquid from the storage box 5 to the steam generator 4. Both the first liquid supply line 3 and the second liquid supply line 6 are connected to the same storage box 5. This reduces the number of storage boxes 5, reduces the number of components used for fluid dispensing, lowers production costs and assembly difficulty, and improves production efficiency.

[0051] It should be noted that, in the embodiments of this application, the first liquid supply path 3 refers to the flow path of fluid such as laundry detergent, and does not specifically refer to a pipeline structure. The second liquid supply path 6 refers to the flow path of fluid such as laundry detergent, and does not specifically refer to a pipeline structure.

[0052] Fabric softener is liquid at room temperature and normal pressure. Room temperature can range from -20°C to 50°C. Normal pressure is one atmosphere.

[0053] Laundry care products include aqueous solutions and functional formulations, including but not limited to detergents, fabric softeners, and / or fragrances.

[0054] Detergent is used to clean clothes. Fabric softener softens, fluffs, and eliminates static electricity in clothes. Fragrance enhancers add a pleasant scent to clothes. Detergent includes, but is not limited to, dry cleaning agents, which are formulations that effectively remove dirt in the absence of water or with minimal water. Dry cleaning agents can be organic solvents, which dissolve and / or adsorb dirt, thus removing it from the clothes and achieving cleaning.

[0055] Steam generator 4 can convert liquid laundry detergent into gaseous steam. In other words, the steam can be gaseous laundry detergent; taking a liquid laundry detergent as an example, the steam includes, but is not limited to, water vapor.

[0056] It is understandable that the second supply line 6 and the first supply line 3 can draw the same fabric softener from the same chamber of the reservoir 5; the second supply line 6 and the first supply line 3 can also draw the same fabric softener from different chambers of the reservoir 5; or the second supply line 6 and the first supply line 3 can draw different fabric softeners from different chambers of the reservoir 5. That is to say, the second supply line 6 and the first supply line 3 can use the same fabric softener, for example, both the second supply line 6 and the first supply line 3 can use water. The second supply line 6 and the first supply line 3 can also use different fabric softeners, for example, the second supply line 6 uses water, and the first supply line 3 uses detergent or fragrance, etc.

[0057] In some embodiments, the liquid storage box 5 has multiple isolated chambers, with a first outlet 5a communicating with one of the chambers and a second outlet 5b communicating with another chamber. The multiple isolated chambers mean that they are not interconnected, and fluid cannot flow between them. Different chambers can contain the same or different fabric care solutions. For example, the chamber communicating with the second outlet 5b contains water, and the chamber communicating with the first outlet 5a contains a functional preparation. With this design, a steam generator generates steam and delivers it to the fabric treatment chamber 1a, while the second liquid supply path 6 simultaneously delivers the functional preparation to the fabric treatment chamber 1a.

[0058] In some embodiments, please refer to Figure 6 and Figure 7 The liquid storage box 5 has a liquid storage cavity 5c, and both the first liquid outlet 5a and the second liquid outlet 5b are connected to the liquid storage cavity 5c. In this way, both the first liquid outlet 5a and the second liquid outlet 5b draw the same type of laundry care liquid from the liquid storage cavity 5c.

[0059] In one embodiment, please refer to Figures 1 to 5 The garment processing equipment includes a steam injection device 2, which has a first fluid inlet 2a and a second fluid inlet 2b. A first liquid supply path 3 connects a first liquid outlet 5a and the first fluid inlet 2a, and a steam outlet 4a connects to the second fluid inlet 2b. The steam injection device 2 injects fluid from both the first fluid inlet 2a and the second fluid inlet 2b into the cylinder assembly 1.

[0060] A steam injection device is a structure used to inject steam in a mist-like form. Examples of steam injection devices include, but are not limited to, nozzles or power pump structures. Steam includes hot steam and cold steam. Cold steam is a mist-like form at room temperature or low temperature after the fluid is dispersed, while hot steam is a high-temperature mist-like form produced by heating and evaporation. An example is the high-temperature mist-like form produced after heating by a steam generator. A power pump structure refers to a mechanism that uses a power source to change the steam flow rate and / or direction. The power source includes, but is not limited to, electrical energy or other energy sources.

[0061] It is understandable that normal temperature refers to a temperature between 20°C and 40°C, while low temperature is below 20°C. High temperature refers to a temperature above 40°C.

[0062] The fluid supplied by the first fluid supply circuit 3 enters the steam injection device 2 through the first fluid inlet 2a, and the steam discharged from the steam outlet 4a enters the steam injection device 2 through the second fluid inlet 2b. The steam and the laundry care liquid then enter the cylinder assembly 1 through the steam injection device 2.

[0063] In this embodiment, the steam generated by the steam generator 4 and the garment care liquid from the first liquid supply line 3 both enter the garment processing chamber 1a through the steam dispensing device 2, increasing the water mist content of the steam, improving the ironing and wrinkle removal effects, and providing good visibility. Furthermore, the steam generator and steam dispensing device can be used to dispense functional agents, simplifying the dispensing path, reducing the number of components used for dispensing functional agents, resulting in high integration and reliability, and low cost.

[0064] In one embodiment, steam from the second fluid inlet 2b and laundry detergent from the first fluid inlet 2a can be mixed in the steam dispensing device 2 before being sprayed into the cylinder assembly 1.

[0065] In one embodiment, the steam injection device 2 includes a nozzle, which includes an injection port, a negative pressure channel, and a liquid channel. The negative pressure channel connects the second fluid inlet 2b and the injection port, and the liquid channel connects the first fluid inlet 2a and the negative pressure channel.

[0066] The nozzle is used to inject fluid into the cylinder assembly 1, such as into the clothing processing chamber 1a.

[0067] The negative pressure flow channel connects the second fluid inlet 2b and the jet nozzle, and steam, such as water vapor, flows through the negative pressure flow channel.

[0068] The liquid flow channel connects the first fluid inlet 2a and the negative pressure flow channel. The liquid flow channel carries the laundry detergent, and the negative pressure flow channel generates negative pressure to draw the laundry detergent from the liquid flow channel into the negative pressure flow channel. In this way, the nozzle can simultaneously spray steam and laundry detergent.

[0069] There are no restrictions on how a negative pressure flow channel generates negative pressure. For example, the flow area of ​​the negative pressure flow channel can be smaller than the flow area of ​​the steam outlet to create negative pressure. Another example is that a vortex structure can be added to the negative pressure flow channel, which causes the hot steam to generate vortices and / or flow separation to create negative pressure.

[0070] In one embodiment, the flow area of ​​the negative pressure channel is smaller than that of the steam outlet. By reducing the flow area of ​​the hot steam, the flow rate of the hot steam is changed. The hot steam from the steam generator flows rapidly through the negative pressure channel. The dynamic pressure in the negative pressure channel is greater than the dynamic pressure at the steam outlet, and the static pressure in the negative pressure channel is less than the static pressure at the steam outlet, thus generating negative pressure. The principle of generating negative pressure in the negative pressure channel can include: the steam generator produces high-temperature and high-pressure hot steam, for example, the steam temperature can reach above 100°C, and the gas pressure inside the steam generator can be greater than one atmosphere. The high-temperature and high-pressure hot steam enters the negative pressure channel through the steam outlet. The dynamic pressure in the negative pressure channel is greater than the dynamic pressure at the steam outlet, and the static pressure in the negative pressure channel is less than the static pressure at the steam outlet. With this design, negative pressure is generated during the flow of hot steam through the negative pressure channel. It is understood that the pressure difference between the steam generator and the negative pressure channel can be used to drive the rapid flow of hot steam without setting a power drive mechanism such as a pumping mechanism to drive the flow of hot steam; alternatively, the flow rate of hot steam can be increased by adding a power drive mechanism such as a pumping mechanism.

[0071] In one embodiment, a vortex structure can be provided in the negative pressure flow channel. The vortex structure can block the flow of hot steam, thereby generating vortices and / or flow separation to form negative pressure. The vortex structure can not only block the steam flow, but also reduce the flow area of ​​the negative pressure flow channel.

[0072] The shape of the vortex structure is not limited. For example, the vortex structure can be in the shape of a convex hull or a spiral, etc. The vortex structure can be set on the wall of the negative pressure flow channel. For example, the vortex structure can be integrally formed with the negative pressure flow channel.

[0073] Spiral shape refers to a vortex structure that is spiral-shaped. Convex hull shape refers to a vortex structure that protrudes from the wall of the negative pressure channel, and the vortex structure can be hemispherical, polyhedral, or irregularly shaped, etc.

[0074] In this embodiment, the negative pressure channel generates negative pressure, allowing the laundry detergent in the liquid channel to enter under this negative pressure. The steam in the negative pressure channel impacts the laundry detergent, dispersing it into a mist, effectively atomizing it. Both the steam and the mist enter the cylinder assembly 1 through the nozzle. This eliminates the need for an additional power pumping mechanism to deliver the laundry detergent into the steam delivery device 2. For example, the first liquid supply path 3 can function without a separate power pumping mechanism; instead, the negative pressure channel generates negative pressure to deliver the laundry detergent into the cylinder assembly 1, saving on the power pumping mechanism, reducing production costs, and simplifying the structural complexity.

[0075] A power pumping mechanism is a mechanism that uses a power source to change the velocity and / or direction of fluid flow. Power sources include, but are not limited to, electrical energy or other energy sources.

[0076] It is understood that a mist-like form refers to the laundry detergent being in the form of particulate droplets. For example, the diameter of a mist-like droplet may not exceed 50 μm. This is merely one example diameter for a mist-like form.

[0077] Taking steam as water vapor and fabric softener as liquid as an example, the water vapor impacts the liquid to produce water mist, thereby increasing the water mist content. The water vapor and water mist sprayed by the steam injection device 2 can remove wrinkles and iron clothes, reducing wrinkles generated during the drying process. During the drying process, the dry and hot airflow dries the clothes. If the temperature of the dry and hot airflow is too high, it will cause the clothes to dry too quickly, resulting in more wrinkles and deeper creases. If the temperature of the dry and hot airflow is too low, it will prolong the drying time and may even fail to achieve the required degree of dryness. In this embodiment, in the final stage of drying, the steam injection device 2 can spray water vapor in a mist-like form into the clothes processing chamber 1a. While the dry and hot airflow dries the clothes, the water vapor in a mist-like form slightly moistens the clothes again. The water vapor in a mist-like form moisturizes and cools the clothes to a certain extent, achieving the effect of ironing clothes. This can effectively improve the problems of more wrinkles and deeper creases caused by drying too quickly.

[0078] Taking steam as water vapor and laundry detergent as dry cleaning agent as an example, the water vapor and mist-like dry cleaning agent sprayed by the steam dispensing device 2 can clean clothes. The water vapor impacts the dry cleaning agent, causing the mixture of dry cleaning agent and water vapor to be sprayed onto the clothes at high speed and high energy. This not only reduces the amount of dry cleaning agent used, but also facilitates the penetration of the dry cleaning agent into the fibers of the clothes. The water vapor can also slightly moisten the clothes, improving the cleaning efficiency.

[0079] In one embodiment, the negative pressure flow channel includes a venturi channel and a suction channel, the suction channel connecting the venturi channel and the liquid flow channel.

[0080] Vapor flow within the Venturi channel creates negative pressure, allowing the fabric softener in the liquid flow channel to enter the Venturi channel through the suction channel under this negative pressure. In other words, the Venturi effect of the Venturi channel is used to generate negative pressure, thereby drawing in the fabric softener. Once the fabric softener enters the Venturi channel, the high-speed vapor within the channel impacts the liquid, causing it to disperse into a mist-like form.

[0081] Steam generator 4 is used to supply steam into the Venturi channel. For example, steam generator 4 can send steam into the Venturi channel to generate negative pressure in the Venturi channel.

[0082] The liquid flow channel is used to deliver laundry detergent to the Venturi channel. For example, the laundry detergent in the reservoir 5 is drawn into the nozzle under the negative pressure of the Venturi channel.

[0083] In one embodiment, the Venturi channel includes a contraction section and a throat section. Along the steam flow direction, the flow area at the first end of the contraction section is larger than the flow area at the second end of the contraction section, and the second end of the contraction section connects to the first end of the throat section. For example, the flow area at the second end of the contraction section is equal to the flow area of ​​the throat section.

[0084] Here, steam first flows through the contraction section and then through the throat section. Specifically, steam first flows through the first end of the contraction section and then through the second end of the contraction section into the throat section. Because the flow area at the first end of the contraction section is larger than that at the second end, the steam is accelerated and depressurized after passing through the contraction section before entering the throat section. The steam velocity in the throat section is greater than the steam velocity at the first end of the contraction section, and the steam pressure in the throat section is lower than the steam pressure in the contraction section. The lower pressure around the outlet of the throat section creates a negative pressure in the suction channel, driving the laundry detergent in the liquid flow channel through the suction channel into the Venturi channel.

[0085] It should be noted that the flow cross-section refers to a cross-section orthogonal to all streamlines of the primary or total flow, that is, a surface perpendicular to the flow velocity clusters, such as steam or laundry detergent. When the streamline clusters are not parallel to each other, the flow cross-section is a curved surface; when the streamline clusters are parallel straight lines, the flow cross-section is a plane. The flow area is the area of ​​the flow cross-section.

[0086] In one embodiment, the flow area of ​​the contraction section gradually decreases from the first end to the second end along the steam flow direction. Thus, the steam velocity gradually increases and the pressure gradually decreases in the contraction section, exhibiting a continuous pressure variation, which reduces the steam turbulence.

[0087] In one embodiment, the flow area at any location in the throat section remains constant. Steam that has been accelerated and depressurized by the contraction section enters the throat section, where it can flow relatively smoothly. The throat section acts as a rectifying element, ensuring that the steam maintains a high flow velocity and low pressure for smooth flow.

[0088] In some embodiments, one end of the suction passage is connected to the Venturi channel located downstream of the throat section in the direction of steam flow. Thus, the flow velocity and pressure downstream of the throat section in the direction of steam flow are relatively faster and lower, thereby generating a larger negative pressure.

[0089] In some embodiments, the liquid reservoir 5 can be connected to a water source. The water source refers to the source from which water is supplied to the liquid reservoir 5. The water source includes, but is not limited to, tap water. That is, the laundry detergent can be a liquid. Tap water can be used to supply the liquid reservoir 5 with liquid.

[0090] In one embodiment, the garment processing device includes a liquid pump located in the second liquid supply line 6 to pump garment care liquid from the liquid storage box 5 into the steam generator 4.

[0091] The type of liquid pump is not limited, but includes, but is not limited to, peristaltic pumps.

[0092] In one embodiment, please refer to Figure 2 , Figure 4 and Figure 6 The garment processing equipment includes a liquid injection box 7 and a liquid storage box 5 with a liquid inlet 5g. The outlet of the liquid injection box 7 is connected to the liquid inlet 5g of the liquid storage box 5. The outlet of the liquid injection box 7 is used to discharge the fluid inside the liquid injection box 7. The liquid inlet 5g of the liquid storage box 5 is used to introduce fluid.

[0093] The filling cartridge 7 is used to inject fabric softener to replenish the storage cartridge 5. For example, a user can add fabric softener to the filling cartridge 7, and the fabric softener in the filling cartridge 7 then enters the storage cartridge 5.

[0094] In this embodiment, the fabric care solution in the injection box 7 can enter the storage box 5. By setting up the injection box 7 and the storage box 5, different liquid storage functions are achieved. The injection box 7 allows users to directly add fabric care solution or inject it through an external pipeline, providing the function of replenishing fabric care solution; the storage box 5 is used to store fabric care solution, and users do not need to touch the storage box 5. Thus, the injection box 7 and the storage box 5 can be set in different locations and / or have different sizes in the garment processing equipment to meet functional requirements and reduce design complexity.

[0095] For example, in one embodiment, the height of the outlet is higher than the height of the liquid inlet 5g. That is, in the vertical direction, the height difference between the outlet and the liquid inlet 5g is greater than zero, which facilitates the entry of the laundry detergent in the injection box 7 into the storage box 5 under the action of gravity.

[0096] In one embodiment, please refer to Figure 2 , Figure 4 and Figure 6 The liquid filling box 7 is located on the front support 9. Firstly, the front support 9 has good structural strength and offers multiple installation positions, providing a suitable location for the liquid filling box 7 and preventing it from interfering with the installation of other components. Secondly, users can see part of the structure of the front support 9 when they open the door, making it convenient for users to add fabric softener to the liquid filling box 7.

[0097] In one embodiment, please refer to Figure 1The garment processing equipment includes a base 8, which is located below the cylindrical assembly 1, and a liquid storage box 5 is disposed on the base 8. The base 8 remains stationary, providing stable and reliable support for the liquid storage box 5. The liquid storage box 5 is positioned lower than the injection box 7 on the base 8 to facilitate the entry of liquid from the injection box 7 into the storage box 5. The storage box 5 also adds weight to the base 8, lowering the overall center of gravity of the garment processing equipment, improving its stability, and reducing vibration and noise.

[0098] In some embodiments, the liquid reservoir 5 may be detachably or non-detachably connected to the base 8. Detachable connections include, but are not limited to, screw connections, bolt connections, or snap-fit ​​connections. Non-detachable connections include, but are not limited to, welding or bonding connections.

[0099] In one embodiment, the front support 9 is disposed at the upper end of the base 8. The base 8 provides support for the front support 9.

[0100] In one embodiment, please refer to Figure 1 , Figure 3 and Figure 5 The height of the liquid storage box 5 is lower than the height of the steam injection device 2. The liquid storage box 5 and the steam injection device 2 are connected by the first liquid supply passage 3. Since the height of the liquid storage box 5 is lower than the height of the steam injection device 2, the first liquid supply passage 3 does not need to be equipped with a valve to control the flow direction of the fluid in the first liquid supply passage 3. This can prevent the liquid in the liquid storage box 5 from flowing to the steam injection device 2 under the action of gravity, thereby improving controllability.

[0101] In one embodiment, please refer to Figure 1 and Figure 4 The liquid storage box 5 is located at the lower left or lower right of the cylindrical assembly 1. The axis of the cylindrical assembly 1 is horizontal or inclined. The distance between the lower left of the cylindrical assembly 1 and the left side plate of the box is relatively large, and the distance between the lower right of the cylindrical assembly 1 and the right side plate of the box is relatively large. In other words, there is a large amount of empty space at the lower left and lower right of the cylindrical assembly 1. The liquid storage box 5 is placed in the empty space, which will not interfere with the existing components of the clothing processing equipment. The shape and size of the liquid storage box 5 can also be designed according to the needs, reducing the design and manufacturing difficulty.

[0102] It should be noted that in the plane perpendicular to the axis of cylinder assembly 1, please refer to... Figure 1 and Figure 4The cylindrical assembly 1 has a first perpendicular line L1 and a second perpendicular line L2. Both the first perpendicular line L1 and the second perpendicular line L2 intersect the axis of the cylindrical assembly 1 perpendicularly. The first perpendicular line L1 extends horizontally, and the second perpendicular line L2 extends vertically. The lower left of the cylindrical assembly 1 refers to the area located below the first perpendicular line L1 and to the left of the second perpendicular line L2. The lower left of the cylindrical assembly 1 also refers to the area located below the first perpendicular line L1 and to the right of the second perpendicular line L2.

[0103] In one embodiment, please refer to Figure 6 and Figure 7 The outer surface of the liquid storage box 5 includes a first stepped surface 5d and a second stepped surface 5e. The height of the second stepped surface 5e is higher than the height of the first stepped surface 5d. An atmospheric connection port 5f is formed on the second stepped surface 5e, and a first liquid outlet 5a and a second liquid outlet 5b are formed on the first stepped surface 5d. The atmospheric connection port 5f connects the chamber inside the liquid storage box 5 to the outside atmosphere. For example, a liquid storage cavity 5c is formed inside the liquid storage box 5, and the first liquid outlet 5a, the second liquid outlet 5b, and the atmospheric connection port 5f are all connected to the liquid storage cavity 5c. The atmospheric connection port 5f connects to the atmosphere, and the air pressure inside the liquid storage cavity 5c is balanced with the atmosphere, so that the laundry care liquid inside the liquid storage box 5 can smoothly enter the first liquid supply path 3 and the second liquid supply path 6.

[0104] In one embodiment, please refer to Figure 6 and Figure 7 The upper surface of the liquid storage box 5 extends upward to form a second stepped surface 5e, and the upper surface of the liquid storage box 5 is recessed downward to form a first stepped surface 5d.

[0105] In one embodiment, please refer to Figure 6 and Figure 7 The liquid storage box 5 includes a box body 51 and a box cover 52, which closes the upward-facing opening of the box body 51 to jointly define the liquid storage cavity 5c. The box cover 52 has a first stepped surface 5d and a second stepped surface 5e.

[0106] In one embodiment, the box body 51 and the box cover 52 are detachably connected. For example, the box body 51 and the box cover 52 are connected by snap-fit, screw connection and / or bolt connection.

[0107] In one embodiment, the connection between the box body 51 and the lid 52 is sealed. For example, the connection between the box body 51 and the lid 52 can be sealed with a sealing ring.

[0108] In one embodiment, the housing 51 and the base 8 can be detachably connected. For example, the housing 51 and the base 8 can be connected by screws or bolts.

[0109] In one embodiment, please refer to Figure 2 and Figure 4The front support 9 has a clothing inlet 9a, and the liquid injection box 7 can be located at the lower left or lower right of the clothing inlet 9a.

[0110] In one embodiment, please refer to Figure 2 and Figure 4 The liquid filling box 7 includes a liquid holding shell 71 and a cover 72. The liquid holding shell 71 has a liquid holding cavity and a liquid replenishment port communicating with the liquid holding cavity. The cover 72 can selectively open or close the liquid replenishment port. The user can open the cover 72 and add laundry detergent to the liquid holding cavity through the liquid replenishment port; when the liquid replenishment is completed or no liquid replenishment is needed, the cover 72 can close the liquid replenishment port.

[0111] The way the cover 72 and the liquid-containing shell 71 are detachably connected is not limited. For example, the cover 72 and the liquid-containing shell 71 can be snapped together or threaded together, etc.

[0112] In one embodiment, the replenishment port and cover 72 can be exposed at the clothing inlet 9a. Thus, when the user opens the door, they can see the replenishment port and cover 72 at the clothing inlet 9a to easily replenish the clothing care solution.

[0113] In one embodiment, please refer to Figures 1 to 5 The garment processing equipment includes a cylindrical assembly 1 with a garment processing chamber 1a and a front support 9. The front support 9 is located on the front side of the cylindrical assembly 1, and both the steam injection device 2 and the steam generator 4 are located on the front support 9. The front support 9 provides an installation position for the steam injection device 2 and the steam generator 4, solving the problem of inconvenient installation of the steam injection device 2 and the steam generator 4. The front support 9 is located on the front side of the cylindrical assembly 1, and the garment injection port 9a of the front support 9 communicates with the garment processing chamber 1a. The steam injection device 2 is located on the front support 9 to facilitate the smooth entry of the fluid ejected from the steam injection device 2 into the garment processing chamber 1a.

[0114] In one embodiment, the steam generator 4 and the steam injection device 2 are both located on the same side of the centerline extending vertically from the front support 9. For example, the steam generator 4 and the steam injection device 2 are both located to the left of the centerline extending vertically from the front support 9. Alternatively, the steam generator 4 and the steam injection device 2 are both located to the right of the centerline extending vertically from the front support 9. This design results in a closer distance between the steam generator 4 and the steam injection device 2, allowing steam to enter the steam injection device 2 more quickly and reducing energy loss during steam flow.

[0115] It should be noted that the centerline of the front support 9 extending in the vertical direction refers to the centerline extending in the vertical direction and intersecting with the axis of the cylinder assembly 1.

[0116] In some embodiments, both the steam generator 4 and the steam injection device 2 are located at the upper left or upper right of the front support 9.

[0117] It is understood that in a plane perpendicular to the axis of the cylinder assembly 1, the front support 9 has horizontally extending bisectors that intersect the axis of the cylinder assembly 1 perpendicularly and the centerline. The upper left portion of the front support 9 refers to the portion above the bisectors and to the left of the centerline. The upper right portion of the front support 9 refers to the portion above the bisectors and to the right of the centerline.

[0118] In one embodiment, the steam generator 4, the steam injection device 2, and the liquid injection box 7 are all located on the same side of the center line extending vertically from the front support 9. For example, the steam generator 4, the steam injection device 2, and the liquid injection box 7 are all located to the left of the center line extending vertically from the front support 9. Alternatively, the steam generator 4, the steam injection device 2, and the liquid injection box 7 are all located to the right of the center line extending vertically from the front support 9. This facilitates pipe routing and reduces the difficulty of pipe installation.

[0119] In one embodiment, please refer to Figure 1 and Figure 4 The garment handling equipment includes a cylindrical assembly 1 with a garment handling chamber 1a and a front support 9 with a garment inlet 9a. The front support 9 is located on the front side of the cylindrical assembly 1. The first liquid supply line 3 and the second liquid supply line 6 are both located to the left or right of the garment inlet 9a. For example, the first liquid supply line 3 and the second liquid supply line 6 are both located to the left of the garment inlet 9a. Alternatively, the first liquid supply line 3 and the second liquid supply line 6 are both located to the right of the garment inlet 9a. The front support 9 provides an installation position for the first liquid supply line 3 and the second liquid supply line 6. In the left-right direction, the first liquid supply line 3 and the second liquid supply line 6 are both located on the same side of the garment inlet 9a, which facilitates centralized pipe routing, makes the pipe layout more organized and clear, allows for more concentrated assembly by operators, and reduces assembly difficulty.

[0120] In one embodiment, please refer to Figure 1 and Figure 4 The first liquid supply line 3 and the second liquid supply line 6 are both located on the front side of the front support 9. The front side of the front support 9 has an open space to avoid interference between the first liquid supply line 3 and the second liquid supply line 6 and the cylinder assembly 1.

[0121] In one embodiment, please refer to Figures 1 to 7 The garment processing equipment includes a first pipe 31, which connects a first liquid outlet 5a and a first fluid inlet 2a. The first pipe 31 constitutes a first liquid supply path 3.

[0122] In one embodiment, please refer to Figures 1 to 7The garment processing equipment includes a second pipe 61 and a third pipe 101. The second pipe 61 connects the second liquid outlet 5b and the liquid inlet 4b of the steam generator 4, and the third pipe 101 connects the steam outlet 4a and the second fluid inlet 2b. The second pipe 61 can form a second liquid supply circuit 6.

[0123] In one embodiment, please refer to Figures 1 to 7 The garment processing equipment includes a fourth pipe 102, which connects the outlet of the liquid injection box 7 and the liquid inlet 5g of the liquid storage box 5.

[0124] It should be noted that the first pipe 31 mentioned above can be a single complete pipe or it can be composed of multiple pipe segments connected together; there is no limitation on this.

[0125] The aforementioned second pipe 61 can be a single, complete pipe or composed of multiple pipe segments connected together; no restriction is imposed here.

[0126] The aforementioned third pipe 101 can be a single complete pipe or a combination of multiple pipe segments; no restrictions are imposed here.

[0127] The aforementioned fourth pipe 102 can be a single, complete pipe or a series of connected pipe sections; no restrictions are imposed here.

[0128] In one embodiment, please refer to Figures 3 to 5 The steam injection device 2 includes a main body 21, a first connector 22, and a second connector 23. The first connector 22 forms a first fluid inlet 2a, and the second connector 23 forms a second fluid inlet 2b. The main body 21 is located behind the front support 9, and both the first connector 22 and the second connector 23 extend through the front support 9 to the front side of the front support 9. The first connector 22 and the second connector 23 are connected to the main body 21.

[0129] For example, the channel in the first connector 22 is part of a liquid flow channel, and the channel in the second connector 23 is part of a negative pressure flow channel.

[0130] In this embodiment, the main body 21 is located behind the front support 9 to facilitate the injection of steam and garment care liquid into the garment processing chamber 1a. The first connector 22 and the second connector 23 extend to the front of the front support 9. The front of the front support 9 has an open space without the obstruction of the cylindrical assembly 1, which facilitates the connection of the first connector 22 to the first pipe 31 and the second connector 23 to the third pipe 101. This makes assembly convenient and also prevents the first pipe 31 and the third pipe 101 from entering between the front support 9 and the cylindrical assembly 1, thus avoiding interference.

[0131] In one embodiment, the main body 21 includes a shell and a core. The shell has a placement cavity and a spray port. The core is housed in the placement cavity and has a Venturi channel and a suction channel. A first connector 22 and a second connector 23 are both connected to the shell. The first connector 22 has a liquid inlet section, and the second connector 23 has an air inlet section. The negative pressure flow channel includes the air inlet section, and the liquid flow channel includes the placement cavity and the liquid inlet section. The air inlet section communicates with the Venturi channel, and the liquid inlet section communicates with the placement cavity.

[0132] For example, the Venturi channel can extend along the length of the core, one end of the suction channel is connected to the Venturi channel, and the other end of the suction channel can penetrate the circumferential surface of the core.

[0133] It is understandable that the circumferential surface of the core refers to the outer surface that surrounds the core along its length.

[0134] In this embodiment, steam from the second fluid inlet 2b flows sequentially through the air intake section, the venturi channel, and the spray nozzle; laundry detergent from the first fluid inlet 2a flows sequentially through the liquid inlet section, the placement chamber, the suction channel, and the spray nozzle.

[0135] For example, the shell and core can be manufactured separately to reduce manufacturing difficulty. The core is housed within the placement cavity, resulting in a compact overall structure and smaller overall size for the steam delivery device 2.

[0136] In one embodiment, the housing includes a first shell and a second shell. The first shell has an opening slot, and the second shell closes the opening of the opening slot to define a placement cavity. An injection port is formed on the outer surface of the second shell away from the first shell. In this way, the core can be assembled into the opening slot through the opening slot, and then the second shell is used to close the opening of the opening slot to complete the assembly of the housing and the core. The assembly is simple and convenient.

[0137] In one embodiment, the core is detachably disposed in the placement cavity, and the second shell detachably covers the opening of the slot. This allows the core to be removed for maintenance, such as cleaning or replacement, without damaging the shell when maintenance is required.

[0138] The detachable connection method between the second shell and the first shell is not limited. For example, the second shell and the first shell can be connected by threads or by snap-fit, etc.

[0139] For example, in one embodiment, the first shell, the first connector 22, and the second connector 23 can be integrally formed. This reduces assembly steps, eliminates the need for seals at the connection between the first shell and the first connector 22, and at the connection between the first shell and the second connector 23, thus reducing the use of seals.

[0140] The first connector 22 can be roughly hollow cylindrical in shape to facilitate connection to the first pipe 31.

[0141] The second connector 23 can be roughly hollow cylindrical in shape to facilitate connection to the third pipe 101.

[0142] For example, the steam generator 4 can generate steam by heating. In one embodiment, the steam generator 4 includes a housing and a heating element. The housing forms a steam outlet 4a and a liquid inlet 4b. The housing has a heating chamber, and both the steam outlet 4a and the liquid inlet 4b are in communication with the heating chamber. At least a portion of the heating element is located within the heating chamber. Laundry detergent enters the heating chamber through the liquid inlet 4b, and the heating element heats the laundry detergent within the heating chamber to generate steam. The steam is discharged through the steam outlet 4a to the second fluid inlet 2b.

[0143] In this embodiment, the high-temperature and high-pressure steam generated in the heating chamber enters the steam dispensing device 2, for example, into the negative pressure channel. The high-speed flowing steam can generate negative pressure in the negative pressure channel, allowing the laundry detergent from the first liquid supply line 3 to enter the steam dispensing device 2, for example, into the liquid channel. The laundry detergent from the first liquid supply line 3 can cool the steam in the steam dispensing device 2, which can prevent the steam temperature from being too high. The high-speed steam impacts the laundry detergent to generate droplets that are sprayed into the cylinder assembly 1.

[0144] In one embodiment, please refer to Figure 2 , Figure 3 and Figure 5 Steam outlet 4a is formed on the side wall of the casing facing the steam injection device 2. For example, the steam injection device 2 is located on the right side of the casing, and steam outlet 4a is formed on the right side wall of the casing. In this way, the distance between steam outlet 4a and steam injection device 2 is relatively short, and the path of steam from steam outlet 4a to second fluid inlet 2b is relatively short, which can minimize the length of third pipe 101 and reduce energy loss during steam flow.

[0145] In one embodiment, the liquid inlet 4b may be formed on the side wall of the housing away from the steam injection device 2. For example, the liquid inlet 4b may be formed on the left side wall of the housing.

[0146] In one embodiment, the heating element can convert electrical energy into heat energy; for example, the heating element can be a resistance heating structure. The heating element can also be other types of heating structures.

[0147] In one embodiment, the garment handling device includes a circulating air duct. At least one air inlet communicating with the garment handling chamber 1a is formed on the rear sidewall of the garment collecting drum 11. The circulating air duct connects the air inlet and the air outlet of the garment handling chamber 1a. The circulating air duct provides a circulating airflow that repeatedly flows through the garment handling chamber 1a. The airflow in the circulating air duct can enter the garment handling chamber 1a through the air inlet, and the airflow in the garment handling chamber 1a can enter the circulating air duct through the air outlet. The airflow can circulate between the circulating air duct and the garment handling chamber 1a.

[0148] Understandably, the number of air inlets can be one or more, such as two, three, four, or five, etc.

[0149] In one embodiment, the base 8 has a heat exchange channel, which is part of the circulating air duct.

[0150] In one embodiment, the garment processing device includes a heat exchange component located within a heat exchange channel. The heat exchange component exchanges heat with the airflow within the heat exchange channel, thereby dehumidifying and heating. The humid and hot airflow in the garment processing chamber 1a enters the heat exchange channel and undergoes heat and mass exchange with the heat exchange component, transforming into dry and hot airflow. The dry and hot airflow then flows back into the garment processing chamber 1a through the air inlet.

[0151] In some embodiments, the heat exchange assembly includes a condenser and an evaporator. The garment handling device 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, and the refrigerant can circulate within the heat pump system. 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 used to cool and dehumidify the humid, hot airflow from the garment handling chamber 1a into a dry, cold airflow; the condenser heats the dry, cold airflow into a dry, hot airflow and returns it to the garment handling chamber 1a.

[0152] 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 cools and dehumidifies the hot, humid airflow from the clothing processing chamber 1a, forming a dry, cool airflow. The condenser heats the dry, cool airflow into a hot, dry airflow, which then flows back into the clothing processing chamber 1a. The hot, dry airflow returning to the clothing processing chamber 1a comes into contact with the damp clothing, forming a hot, humid airflow again, completing one drying cycle. By repeatedly running the drying cycle, circulating airflow is continuously supplied to the clothing processing chamber 1a to dry the clothes.

[0153] For example, both the evaporator and the condenser can be finned tube heat exchangers.

[0154] For example, throttling devices include, but are not limited to, electronic expansion valves, etc.

[0155] In one embodiment, the garment processing device includes a fan wheel for driving airflow. Exemplarily, the fan wheel is located within a heat exchange channel. During the garment drying process, the fan wheel drives the airflow passing through the garment sequentially through an evaporator and a condenser before blowing it onto the garment to form a circulating airflow. The fan wheel can accelerate airflow and improve drying efficiency.
