[0032] The functions of the laundry treatment device provided by the embodiments of the present application are not limited. Exemplarily, the laundry treatment device may have a drying function. The drying function can be used to dry clothes. The laundry treatment device may also have a washing function, and the washing function is used to clean clothes. For example, the laundry treatment device may be a dryer or a washer-dryer, etc.

[0033] Please refer to Figure 1 and Figure 2 , the laundry treatment device may include a drum assembly 1, and the axis of the drum assembly 1 may extend along a horizontal direction or an inclined direction. The drum assembly 1 has a laundry treatment chamber 1a for placing clothes.

[0034] The axis of the drum assembly 1 extending along the inclined direction means that the axis of the drum assembly 1 intersects obliquely with the horizontal direction.

[0035] In one embodiment, please continue to refer to Figure 1 and Figure 2 , the drum assembly 1 includes a rotatable laundry drum 11, and the laundry drum 11 has a loading and unloading opening facing forward. The laundry drum 11 has a laundry treatment chamber 1a, and the laundry drum 11 can be used to place loads such as clothes. The user puts clothes into or takes clothes out of the laundry drum 11 through the loading and unloading opening from the front. The laundry drum 11 can rotate. During the rotation of the laundry drum 11, the clothes are driven to move from the lower part to the upper part; under the action of gravity, the clothes fall from the upper part to the lower part. In this way, the clothes are dispersed, beaten and their postures are changed under the combined action of the laundry drum 11 and gravity.

[0036] In some embodiments, please refer to Figure 1 and Figure 2 , the laundry drum 11 may be generally in the shape of a hollow cylinder.

[0037] In some embodiments, the drum assembly 1 includes an outer tub, and the laundry drum 11 may be disposed in the outer tub. The outer tub can remain stationary. It can be understood that the outer tub may or may not be provided outside the laundry drum 11.

[0038] In some embodiments, please refer to Figure 1 and Figure 2 , the drum assembly 1 may only have the laundry drum 11 without the above-mentioned outer tub. In this embodiment, the laundry drum 11 may be a single-drum structure. That is to say, the laundry treatment device only has one drum, namely the laundry drum 11.

[0039] In some embodiments, please refer to Figure 1 and Figure 2, the laundry treatment device may include a front support 9, the axis of the drum assembly 1 extends in a horizontal direction or an inclined direction, and the front support 9 may be disposed at the front end of the drum assembly 1. The front support 9 can provide a supporting force for the drum assembly 1.

[0040] The front support 9 may have a laundry loading opening 9a, and the laundry loading opening 9a communicates with the laundry treatment chamber 1a. Taking the single-drum structure of the laundry drum 11 as an example, the laundry drum 11 may be connected to the front support 9 through a dynamic seal, and the laundry loading opening 9a communicates with the access opening.

[0041] In some embodiments, the laundry treatment device includes a cabinet, the drum assembly 1 and the front support 9 are both disposed in the cabinet, and the cabinet is provided with an opening communicating with the laundry treatment chamber 1a of the drum assembly 1.

[0042] In some embodiments, the cabinet may be generally hexahedral, for example, cube-shaped or cuboid-shaped.

[0043] In some embodiments, the laundry treatment device includes a door body, and the door body is used to selectively open or close the opening of the cabinet.

[0044] Please refer to Figure 1 and Figure 2 , an embodiment of the present application provides a laundry treatment device, which includes a laundry treatment chamber 1a, a steam delivery device 2, a fluid supply unit, and a steam generator 4.

[0045] Please refer to Figures 1 to 5 , the steam delivery device 2 has a first fluid inlet 2a and a second fluid inlet 2b, and the steam delivery device 2 delivers the fluids from the first fluid inlet 2a and the second fluid inlet 2b into the laundry treatment chamber 1a. The fluid supply unit is communicated with the first fluid inlet 2a. The steam generator 4 has a steam outlet 4a, and the steam outlet 4a is communicated with the second fluid inlet 2b.

[0046] The steam generator 4 is used to generate steam, and the steam outlet 4a is used to discharge steam.

[0047] The fluid supply unit is used to provide a liquid laundry care solution.

[0048] It can be understood that both gaseous steam and liquid laundry care solution are fluids.

[0049] The steam delivery device is a structure for delivering steam, and the steam is in a foggy state. Exemplarily, the steam delivery device includes, but is not limited to, a nozzle or a power pump structure, etc. The steam includes hot steam and cold steam. The cold steam is a normal-temperature or low-temperature foggy state presented after the fluid is dispersed, and the hot steam is a high-temperature foggy state generated by heating and evaporation. Exemplarily, it is the high-temperature foggy state generated after the steam generator is heated. The power pump structure refers to a mechanism that uses a power source to provide power to change the steam flow rate and / or direction. The power source includes, but is not limited to, electric energy or other energy sources.

[0050] It can be understood that the normal temperature refers to a temperature of 20°C to 40°C, and the low temperature is lower than 20°C. The high temperature refers to a temperature higher than 40°C.

[0051] The fluid provided by the fluid supply unit enters the steam delivery device 2 through the first fluid inlet 2a, and the steam discharged from the steam outlet 4a enters the steam delivery device 2 through the second fluid inlet 2b. Then, the steam and the fabric care liquid enter the cylinder assembly 1 through the steam delivery device 2.

[0052] In the clothes treatment device provided by the embodiment of the present application, the steam generated by the steam generator 4 and the fabric care liquid of the fluid supply unit both enter the clothes placement cavity 1a through the steam delivery device 2, increasing the water mist content of the steam, improving the ironing and wrinkle removal effects, and having good visualization effects. Moreover, the steam generator and the steam delivery device can be used to deliver functional preparations, which can simplify the delivery path of the functional preparations, reduce the components for delivering the functional preparations, and have high integration and reliability and low cost.

[0053] The fabric care liquid is in a liquid state at room temperature and normal pressure. Exemplarily, the room temperature can be -20°C to 50°C. The normal pressure can be one atmosphere.

[0054] The fabric care liquid includes a water solution and a functional preparation. The functional preparation includes, but is not limited to, detergents, fabric softeners, and / or fragrance enhancers, etc.

[0055] The detergent is used to clean clothes. The fabric softener plays roles such as softening, fluffing, and eliminating static electricity on clothes. The fragrance enhancer is used to increase the fragrance of clothes. The detergent includes, but is not limited to, dry cleaning agents. The dry cleaning agent is a preparation that can effectively remove dirt under anhydrous or slightly aqueous conditions. The dry cleaning agent can be an organic solvent, and the organic solvent makes the dirt detach from the clothes by dissolving and / or adsorbing the dirt to achieve clothes cleaning.

[0056] The steam generator 4 can convert the liquid fabric care liquid into gaseous steam. That is to say, the steam can be the gaseous fabric care liquid. Taking the water solution of the fabric care liquid as an example, the steam includes, but is not limited to, water vapor.

[0057] In one embodiment, the steam from the second fluid inlet 2b and the fabric care liquid from the first fluid inlet 2a can be mixed within the steam delivery device 2 and then sprayed into the barrel assembly 1.

[0058] In one embodiment, the steam delivery device 2 includes a nozzle. The nozzle includes a spray opening, a negative pressure flow channel, and a liquid flow channel. The negative pressure flow channel communicates with the second fluid inlet 2b and the spray opening, and the liquid flow channel communicates with the first fluid inlet 2a and the negative pressure flow channel.

[0059] The spray opening is used to spray fluid into the barrel assembly 1, such as into the laundry treatment chamber 1a.

[0060] The negative pressure flow channel communicates with the second fluid inlet 2b and the spray opening, and the negative pressure flow channel allows steam, such as water vapor, to flow through.

[0061] The liquid flow channel communicates with the first fluid inlet 2a and the negative pressure flow channel. The liquid flow channel allows the fabric care liquid to flow through. The negative pressure flow channel can generate negative pressure to suck the fabric care liquid in the liquid flow channel into the negative pressure flow channel. In this way, the spray opening can spray out steam and the fabric care liquid simultaneously.

[0062] The manner of generating negative pressure in the negative pressure flow channel is not limited. For example, the cross-sectional area of the negative pressure flow channel can be smaller than the cross-sectional area of the steam outlet to form negative pressure. Another example is that a vortex structure can be added in the negative pressure flow channel. The vortex structure causes the hot steam to generate vortices and / or flow separation to form negative pressure.

[0063] In one embodiment, the cross-sectional area of the negative pressure flow channel is smaller than the cross-sectional area of the steam outlet. By reducing the cross-sectional area of the hot steam, the flow rate of the hot steam is changed. The hot steam from the steam generator rapidly flows through the negative pressure flow channel. The dynamic pressure in the negative pressure flow channel is greater than the dynamic pressure at the steam outlet, and the static pressure in the negative pressure flow channel is less than the static pressure at the steam outlet. The negative pressure flow channel can generate negative pressure. The principle of generating negative pressure in the negative pressure flow channel can include: The steam generator generates high-temperature and high-pressure hot steam. For example, the temperature of the steam can reach above 100°C, and the air pressure in the steam generator can be greater than one atmosphere. The high-temperature and high-pressure hot steam enters the negative pressure flow channel through the steam outlet. The dynamic pressure in the negative pressure flow channel is greater than the dynamic pressure at the steam outlet, and the static pressure in the negative pressure flow channel is less than the static pressure at the steam outlet. With such a design, negative pressure is generated during the process of the hot steam flowing through the negative pressure flow channel. It can be understood that the pressure difference between the steam generator and the negative pressure flow channel can be used to drive the rapid flow of the hot steam without setting a power driving mechanism, such as a pumping mechanism, to drive the hot steam flow; or a power driving mechanism, such as a pumping mechanism, can be added to accelerate the flow rate of the hot steam.

[0064] In one embodiment, a vortex structure can be provided in the negative pressure flow channel. The vortex structure can block the flow of the hot steam to generate vortices and / or flow separation to form negative pressure. The vortex structure can not only block the steam flow but also reduce the cross-sectional area of the negative pressure flow channel.

[0065] The shape of the eddy current structure is not limited. Exemplarily, the eddy current structure can be in the shape of a convex hull, or in a spiral shape, etc. The eddy current structure can be arranged on the wall surface of the negative pressure flow channel. For example, the eddy current structure can be integrally formed with the negative pressure flow channel.

[0066] The spiral shape means that the eddy current structure is in a spiral linear shape. The convex hull shape means that the eddy current structure protrudes from the wall surface of the negative pressure flow channel, and the eddy current structure is in a hemispherical shape, a polyhedral shape, or an irregular special shape, etc.

[0067] In this embodiment, the negative pressure flow channel can generate negative pressure so that the clothing care liquid in the liquid flow channel enters the negative pressure flow channel under the action of the negative pressure. The steam in the negative pressure flow channel impacts the clothing care liquid, causing the clothing care liquid to disperse into mist-like droplets, that is, it plays the role of atomizing the clothing care liquid. In this way, both the steam and the mist-like droplets enter the cylinder assembly 1 through the ejection port. In this way, a power pumping mechanism for pumping the clothing care liquid into the steam delivery device 2 can be not additionally provided. For example, the first liquid supply path 3 can be not additionally provided with a power pumping mechanism, but the negative pressure flow channel is used to generate negative pressure to transport the clothing care liquid into the cylinder assembly 1, saving the power pumping mechanism, reducing the production cost, and simplifying the structural complexity.

[0068] The power pumping mechanism refers to a mechanism that a power source provides power to change the flow rate and / or flow direction of a fluid. The power source includes but is not limited to electric energy or other energy sources.

[0069] It can be understood that the mist-like form means that the clothing care liquid is in the form of granular droplets. Exemplarily, the diameter of the droplets in the mist-like form can be no more than 50 μm (micrometers). This is only an example diameter of the mist-like form.

[0070] Taking steam as water vapor and the clothing care liquid as water liquid as an example, the water vapor impacts the water liquid to generate water mist, thereby increasing the water mist content. The water vapor and water mist ejected by the steam delivery device 2 can remove wrinkles and iron the clothing, reducing the wrinkles generated during the drying process of the clothing. During the drying process of the clothing, the hot and dry air flow dries the clothing. If the temperature of the hot and dry air flow is too high, it will cause the clothing to dry too quickly, resulting in problems such as more wrinkles and deeper creases on the clothing; if the temperature of the hot and dry air flow is too low, it will prolong the drying time and even fail to reach the required drying degree. In the embodiment of the present application, in the last stage of drying the clothing, the water vapor carrying the mist-like droplets can be ejected into the clothing treatment chamber 1a through the steam delivery device 2. While the hot and dry air flow dries the clothing, the water vapor carrying the mist-like droplets slightly wets the clothing again, using the water vapor carrying the mist to humidify and cool the clothing to a certain extent, achieving the effect of ironing the clothing, and can effectively improve problems such as more wrinkles and deeper creases caused by too fast drying.

[0071] Taking steam as water vapor and the fabric care liquid as dry cleaning agent as an example, the water vapor and the dry cleaning agent in the form of atomized droplets ejected by the steam delivery device 2 can clean the clothes. The water vapor impacts the dry cleaning agent, causing the mixture of the dry cleaning agent and the water vapor to be sprayed onto the clothes in a high-speed and high-energy atomized state. This not only reduces the dosage of the dry cleaning agent but also facilitates the penetration of the dry cleaning agent into the interior of the fabric fibers. The water vapor can slightly moisten the clothes, improving the decontamination efficiency.

[0072] In one embodiment, the negative pressure flow channel includes a Venturi channel and an inhalation channel. The inhalation channel communicates with the Venturi channel and the liquid flow channel.

[0073] Steam flows in the Venturi channel to generate negative pressure, so that the fabric care liquid in the liquid flow channel enters the Venturi channel through the inhalation channel under the action of the negative pressure. That is, the Venturi effect of the Venturi channel is utilized to generate negative pressure to suck in the fabric care liquid. After the fabric care liquid enters the Venturi channel, the high-speed steam in the Venturi channel impacts the fabric care liquid, causing the fabric care liquid to be dispersed into atomized droplets.

[0074] The steam generator 4 is used to deliver steam to the Venturi channel. For example, the steam generator 4 can send steam into the Venturi channel to generate negative pressure in the Venturi channel.

[0075] The liquid flow channel is used to deliver the fabric care liquid to the Venturi channel. For example, the fabric care liquid in the liquid storage box 5 is sucked into the nozzle under the negative pressure of the Venturi channel.

[0076] In one embodiment, the Venturi channel includes a contraction section and a throat section. Along the flow direction of the steam, the cross-sectional area of the first end of the contraction section is larger than the cross-sectional area of the second end of the contraction section. The second end of the contraction section communicates with the first end of the throat section. Exemplarily, the cross-sectional area of the second end of the contraction section is equal to the cross-sectional area of the throat section.

[0077] Here, the steam first flows through the contraction section and then through the throat section. Specifically, the steam first flows through the first end of the contraction section and then enters the throat section through the second end of the contraction section. Since the cross-sectional area of the first end of the contraction section is larger than the cross-sectional area of the second end of the contraction section, the steam is accelerated and decompressed after passing through the contraction section and then enters the throat section. The flow rate of the steam in the throat section is greater than the flow rate of the steam at the first end of the contraction section. The air pressure of the steam in the throat section is less than the air pressure of the steam in the contraction section. The air pressure around the outlet of the throat section is relatively small, causing negative pressure to be generated in the inhalation channel to drive the fabric care liquid in the liquid flow channel to enter the Venturi channel through the inhalation channel.

[0078] It should be noted that the cross-sectional area of the flow is a cross-section orthogonal to all streamlines of the elementary flow or the total flow, that is, a plane perpendicular to the flow velocity cluster such as steam or fabric care liquid. When the streamline clusters are not parallel to each other, the cross-sectional area of the flow is a curved surface; when the streamline clusters are parallel straight lines to each other, the cross-sectional area of the flow is a plane. The cross-sectional area of the flow is the area of the cross-sectional area of the flow.

[0079] In one embodiment, the flow-through area of the contraction section gradually decreases from the first end to the second end along the steam flow direction. Thus, the flow velocity of the steam gradually increases and the air pressure gradually decreases in the contraction section, and the air pressure shows a continuous change trend, which can reduce the turbulence degree of the steam.

[0080] In one embodiment, the flow-through area at any position of the throat section remains unchanged. The steam that has been accelerated and depressurized in the contraction section enters the throat section, and the steam can flow relatively smoothly in the throat section. The throat section plays a rectifying role to enable the steam to flow smoothly at a relatively high flow velocity and a relatively low air pressure.

[0081] In some embodiments, one end of the suction channel is connected to the downstream of the throat section along the steam flow direction. Thus, the flow velocity is relatively faster and the air pressure is relatively smaller at the downstream of the throat section along the steam flow direction, so as to generate a relatively large negative pressure.

[0082] In some embodiments, the fluid supply part includes a first liquid supply path 3, a second liquid supply path 6 and a plurality of containers. The first liquid supply path 3 is connected to the first fluid inlet 2a and at least one container, and the second liquid supply path 6 is connected to the liquid inlet of the steam generator 4 and the remaining containers. The containers are used to contain liquid fabric care liquid. Taking two containers as an example, the first liquid supply path 3 is connected to the first fluid inlet 2a and one container, and the second liquid supply path 6 is connected to the liquid inlet of the steam generator 4 and the other container. The first liquid supply path 3 and the second liquid supply path 6 are connected to different containers. That is to say, the steam generator 4 and the first liquid supply path 3 can suck fluid from different containers. The plurality of containers can contain different types of fabric care liquid. Thus, the types of fabric care liquid for the steam generator 4 and the first liquid supply path 3 can be differentiated. Of course, the plurality of containers can also contain the same type of fabric care liquid, and the steam generator 4 and the first liquid supply path 3 can also use the same fabric care liquid, with more selectivity and richer functions.

[0083] It can be understood that the steam generator 4 and the first liquid supply path 3 can use the same fabric care liquid. For example, both the steam generator 4 and the first liquid supply path 3 use aqueous solution. The steam generator 4 and the first liquid supply path 3 can also use different fabric care liquids. For example, the steam generator 4 uses aqueous solution, and the first liquid supply path 3 uses detergent or flavoring agent, etc.

[0084] In one embodiment, please refer to Figures 1 to 7, the fluid supply unit includes a liquid storage box 5, a first liquid supply path 3, and a second liquid supply path 6. The liquid storage box 5 has a first liquid outlet 5a and a second liquid outlet 5b. The first liquid supply path 3 connects the first liquid outlet 5a and the first fluid inlet 2a, and the second liquid supply path 6 connects the second liquid outlet 5b and the liquid inlet 4b of the steam generator 4. That is to say, both the steam generator 4 and the first liquid supply path 3 are connected to the liquid storage box 5, and both the steam generator 4 and the first liquid supply path 3 draw liquid from the liquid storage box 5.

[0085] The liquid storage box 5 can be used to hold the fabric care liquid. Both the first liquid outlet 5a and the second liquid outlet 5b are used to discharge the fabric care liquid in the liquid storage box 5.

[0086] The liquid inlet 4b of the steam generator 4 is used to receive the fabric care liquid from the second liquid supply path 6.

[0087] In this embodiment, the first liquid supply path 3 transports the fabric care liquid in the liquid storage box 5 to the steam delivery device 2, and the second liquid supply path 6 transports the fabric care liquid in the liquid storage box 5 to the steam generator 4. Both the first liquid supply path 3 and the second liquid supply path 6 are connected to the same liquid storage box 5. In this way, the number of liquid storage boxes 5 can be reduced, the number of components in the fabric treatment device can be reduced, the manufacturing cost and assembly difficulty can be reduced, and the production efficiency can be improved.

[0088] It should be noted that in the embodiment of the present application, the first liquid supply path 3 refers to the flow path of the fluid, such as the fabric care liquid, and does not specifically refer to a pipe structure. The second liquid supply path 6 refers to the flow path of the fluid, such as the fabric care liquid, and does not specifically refer to a pipe structure.

[0089] In one embodiment, please refer to Figure 1 and Figure 4 , the fabric treatment device includes a cylinder assembly 1 having a fabric treatment cavity 1a and a front support 9 having a fabric loading opening 9a. The front support 9 is provided on the front side of the cylinder assembly 1. Both the first liquid supply path 3 and the second liquid supply path 6 are located on the left or right side of the fabric loading opening 9a. For example, both the first liquid supply path 3 and the second liquid supply path 6 are located on the left side of the fabric loading opening 9a. Another example is that both the first liquid supply path 3 and the second liquid supply path 6 are located on the right side of the fabric loading opening 9a. The front support 9 provides an installation position for the first liquid supply path 3 and the second liquid supply path 6. In the left-right direction, both the first liquid supply path 3 and the second liquid supply path 6 are located on the same side of the fabric loading opening 9a, which is convenient for centralized pipe routing, the pipeline layout is more regular and clear, and it is more convenient for operators to assemble centrally, reducing the assembly difficulty.

[0090] In one embodiment, please refer to Figure 1 and Figure 4 , both the first liquid supply path 3 and the second liquid supply path 6 are located on the front side of the front support 9. The front side of the front support 9 has an open space, avoiding interference between the first liquid supply path 3 and the second liquid supply path 6 and the cylinder assembly 1.

[0091] It is understandable that the second liquid supply path 6 and the first liquid supply path 3 can suck the same fabric care liquid from the same chamber of the liquid storage box 5; the second liquid supply path 6 and the first liquid supply path 3 can also suck the same fabric care liquid from different chambers of the liquid storage box 5; the second liquid supply path 6 and the first liquid supply path 3 can also suck different fabric care liquids from different chambers of the liquid storage box 5. That is to say, the second liquid supply path 6 and the first liquid supply path 3 can use the same fabric care liquid. For example, both the second liquid supply path 6 and the first liquid supply path 3 use aqueous solution. The second liquid supply path 6 and the first liquid supply path 3 can also use different fabric care liquids. For example, the second liquid supply path 6 uses aqueous solution, and the first liquid supply path 3 uses detergent or flavorant, etc.

[0092] In some embodiments, please refer to Figure 6 and Figure 7 , the liquid storage box 5 has a liquid storage chamber 5c, and both the first liquid outlet 5a and the second liquid outlet 5b communicate with the liquid storage chamber 5c. In this way, both the first liquid outlet 5a and the second liquid outlet 5b draw the same kind of fabric care liquid.

[0093] In some embodiments, the liquid storage box 5 can be connected to a water source. The water source refers to the source that supplies water flow to the liquid storage box 5. The water source includes but is not limited to tap water. That is to say, the fabric care liquid can be aqueous solution. Tap water can be used to provide aqueous solution to the liquid storage box 5.

[0094] In one embodiment, the laundry treatment device includes a liquid pump, and the liquid pump is arranged on the second liquid supply path 6 to pump the fabric care liquid in the liquid storage box 5 into the steam generator 4.

[0095] The type of the liquid pump is not limited, and the liquid pump includes but is not limited to a peristaltic pump.

The discharge port of the liquid injection box 7 is used to discharge the fluid in the liquid injection box 7. The liquid inlet 5g of the liquid storage box 5 is used to introduce the fluid.

[0097] The liquid injection box 7 is used to inject fabric care liquid to supplement the fabric care liquid in the liquid storage box 5. Exemplarily, the user can add fabric care liquid to the liquid injection box 7, and the fabric care liquid in the liquid injection box 7 then enters the liquid storage box 5.

[0098] In this embodiment, the fabric care liquid in the liquid injection box 7 can enter the liquid storage box 5. By providing the liquid injection box 7 and the liquid storage box 5, different liquid storage functions are achieved respectively. The liquid injection box 7 facilitates the user to directly supplement the fabric care liquid or inject the fabric care liquid through an external pipeline, providing the function of supplementing the fabric care liquid; the liquid storage box 5 is used to store the fabric care liquid, and the user does not need to contact the liquid storage box 5. In this way, the liquid injection box 7 and the liquid storage box 5 can be arranged at different positions and / or have different sizes of the fabric treatment device to meet the functional requirements and reduce the design difficulty.

[0099] In one embodiment, please refer to Figure 2 and Figure 4 , the liquid injection box 7 is arranged on the front support 9. On the one hand, the front support 9 has good structural strength and has more installation positions. The front support 9 is used to provide an installation position for the liquid injection box 7 to prevent the liquid injection box 7 from affecting the installation of other components. On the other hand, when the user opens the door, part of the structure of the front support 9 can be seen. Arranging the liquid injection box 7 on the front support 9 also facilitates the user to add fabric care liquid to the liquid injection box 7.

The base 8 is arranged below the cylindrical body assembly 1, and the liquid storage box 5 is arranged on the base 8. The base 8 remains stationary and can provide stable and good support for the liquid storage box 5. The liquid storage box 5 is arranged on the base 8, and the position of the liquid storage box 5 can be relatively lower than that of the liquid injection box 7, so that the liquid in the liquid injection box 7 can enter the liquid storage box 5. The liquid storage box 5 can also increase the weight of the base 8, lower the overall center of gravity of the fabric treatment device, improve the stability of the fabric treatment device, and reduce vibration and noise.

[0103] Exemplarily, in one embodiment, the discharge port of the liquid injection box 7 is higher than the liquid inlet 5g of the liquid storage box 5. The height of the discharge port is higher than the height of the liquid inlet 5g, that is to say, in the up and down direction, the height difference between the discharge port and the liquid inlet 5g is greater than zero, which facilitates the fabric care liquid in the liquid injection box 7 to enter the liquid storage box 5 under the action of gravity.

[0104] In one embodiment, please refer to Figure 1 and Figure 2, the height of the liquid storage box 5 is lower than that of the steam delivery device 2. The liquid storage box 5 and the steam delivery device 2 are connected through the first liquid supply path 3. Since the height of the liquid storage box 5 is lower than that of the steam delivery device 2, a valve body for controlling the fluid flow direction in the first liquid supply path 3 may not be provided in the first liquid supply path 3, which can prevent the liquid in the liquid storage box 5 from flowing to the steam delivery device 2 under the action of gravity and improve controllability.

[0105] In one embodiment, please refer to Figure 1 , the liquid storage box 5 is located at the lower left or lower right of the cylinder assembly 1.

The distance between the lower left of the cylinder assembly 1 and the left side plate of the box body is relatively large, and the distance between the lower right of the cylinder assembly 1 and the right side plate of the box body is relatively large. That is to say, there is a relatively large empty space at the lower left and lower right of the cylinder assembly 1. The liquid storage box 5 is arranged in the empty space, which will not interfere with the existing components of the clothing treatment device, and the shape and size of the liquid storage box 5 can also be designed according to requirements, reducing the design and manufacturing difficulty.

[0106] It should be noted that in the plane perpendicular to the axis of the cylinder assembly 1, please refer to Figure 4 , the cylinder assembly 1 has a first perpendicular bisector L1 and a second perpendicular bisector L2. Both the first perpendicular bisector L1 and the second perpendicular bisector L2 intersect with the axis of the cylinder assembly 1 and are perpendicular to the axis.

The box cover 52 covers the upward opening of the box body 51 to jointly define a liquid storage cavity 5c. The box cover 52 has a first step surface 5d and a second step surface 5e.

[0110] 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 connection, screw connection, and / or bolt connection.

[0111] In one embodiment, the connection between the box body 51 and the box cover 52 is sealed. For example, the connection between the box body 51 and the box cover 52 can be sealed by a sealing ring.

[0112] In one embodiment, the box body 51 and the base 8 can be detachably connected. For example, the box body 51 and the base 8 are connected by screw connection or bolt connection.

The liquid storage shell 71 has a liquid storage cavity and a liquid replenishing port communicating with the liquid storage cavity. The cover body 72 can selectively open or close the liquid replenishing port. The user can open the cover body 72 and replenish the clothing care liquid into the liquid storage cavity through the liquid replenishing port; when the liquid replenishment is completed or when liquid replenishment is not required, the cover body 72 can close the liquid replenishing port.

[0115] The manner in which the cover body 72 is detachably connected to the liquid storage shell 71 is not limited. Exemplarily, the cover body 72 is snap-connected or thread-connected to the liquid storage shell 71, etc.

[0116] In one embodiment, the liquid replenishing port and the cover body 72 can be exposed at the clothing feeding opening 9a. In this way, when the user opens the door body, the liquid replenishing port and the cover body 72 can be seen at the clothing feeding opening 9a, facilitating the replenishment of the clothing care liquid.

[0117] In one embodiment, please refer to Figure 1 and Figure 4, the laundry treating device includes a front support 9 and a cylinder assembly 1 having a laundry treating chamber 1a.

The front support 9 is disposed on the front side of the cylinder assembly 1, and the laundry loading opening 9a of the front support 9 communicates with the laundry treating chamber 1a. The steam injection device 2 is disposed on the front support 9, facilitating the fluid ejected from the steam injection device 2 to smoothly enter the laundry treating chamber 1a.

[0118] In one embodiment, please refer to Figures 1 to 4 , both the steam generator 4 and the steam injection device 2 are located on the same side of the center line extending in the up and down direction of the front support 9. For example, both the steam generator 4 and the steam injection device 2 are located on the left side of the center line extending in the up and down direction of the front support 9. Another example is that both the steam generator 4 and the steam injection device 2 are located on the right side of the center line extending in the up and down direction of the front support 9. With such a design, the distance between the steam generator 4 and the steam injection device 2 is relatively close, so as to facilitate the steam to enter the steam injection device 2 more quickly and reduce the energy loss during the steam flow.

[0119] It should be noted that the center line extending in the up and down direction of the front support 9 means that the center line extends in the up and down direction and intersects with the axis of the cylinder assembly 1.

[0120] In some embodiments, both the steam generator 4 and the steam injection device 2 are located in the upper left part or the upper right part of the front support 9.

[0121] It can be understood that in a plane perpendicular to the axis of the cylinder assembly 1, the front support 9 has an equidistant line extending in the horizontal direction. The equidistant line is perpendicular to and intersects with the axis of the cylinder assembly 1 and the center line. The upper left part of the front support 9 refers to the part above the equidistant line of the front support 9 and to the left of the center line. The upper right part of the front support 9 refers to the part above the equidistant line of the front support 9 and to the right of the center line.

[0122] In one embodiment, please refer to Figures 1 to 4 , 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 in the up and down direction of the front support 9. For example, the steam generator 4, the steam injection device 2 and the liquid injection box 7 are all located on the left side of the center line extending in the up and down direction of the front support 9. Another example is that the steam generator 4, the steam injection device 2 and the liquid injection box 7 are all located on the right side of the center line extending in the up and down direction of the front support 9. In this way, it is convenient for pipe routing and reduces the difficulty of pipeline layout.

[0126] It should be noted that the above-mentioned first conduit 31 may be a complete pipe body or may be formed by connecting multiple pipe bodies, and no limitation is made herein.

[0127] The above-mentioned second conduit 61 may be a complete pipe body or may be formed by connecting multiple pipe bodies, and no limitation is made herein.

[0128] The above-mentioned third conduit 101 may be a complete pipe body or may be formed by connecting multiple pipe bodies, and no limitation is made herein.

[0129] The above-mentioned fourth conduit 102 may be a complete pipe body or may be formed by connecting multiple pipe bodies, and no limitation is made herein.

[0130] In one embodiment, referring to Figures 1 to 5 , the steam delivery device 2 includes a main body 21, a first joint 22 and a second joint 23. The first joint 22 forms a first fluid inlet 2a, the second joint 23 forms a second fluid inlet 2b. The main body 21 is located at the rear side of the front support 9, and both the first joint 22 and the second joint 23 pass through the front support 9 and extend to the front side of the front support 9. The first joint 22 and the second joint 23 are connected to the main body 21.

[0131] Exemplarily, the channel in the first joint 22 is a part of the liquid flow channel, and the channel in the second joint 23 is a part of the negative pressure flow channel.

[0132] In this embodiment, the main body 21 is located at the rear side of the front support 9, so that the sprayed steam and the clothing care liquid can enter the clothing treatment cavity 1a. The first joint 22 and the second joint 23 extend to the front side of the front support 9. The space on the front side of the front support 9 is open and will not be blocked by the cylinder assembly 1, so that the first joint 22 can be connected to the first pipeline 31 and the second joint 23 can be connected to the third pipeline 101. The assembly operation is convenient, and it can also prevent the first pipeline 31 and the third pipeline 101 from entering between the front support 9 and the cylinder assembly 1, causing interference.

[0133] In one embodiment, the main body 21 includes a housing and a core. The housing is formed with a placement cavity and a spray port. The core is accommodated in the placement cavity. The core is formed with a Venturi channel and a suction channel. Both the first joint 22 and the second joint 23 are connected to the housing. The first joint 22 has a liquid inlet section, and the second joint 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.

[0134] Exemplarily, the Venturi channel can extend along the length direction of the core. One end of the suction channel communicates with the Venturi channel, and the other end of the suction channel can penetrate the circumferential surface of the core.

[0135] It can be understood that the circumferential surface of the core refers to the outer surface surrounding the length direction of the core.

[0136] In this embodiment, the steam from the second fluid inlet 2b flows through the air inlet section, the Venturi channel and the spray port in sequence; the clothing care liquid from the first fluid inlet 2a flows through the liquid inlet section, the placement cavity, the suction channel and the spray port in sequence.

[0137] Exemplarily, the housing and the core can be independently manufactured to reduce the manufacturing difficulty. Accommodating the core in the placement cavity makes the overall structure of the steam delivery device 2 compact and the overall size smaller.

[0138] In one embodiment, the housing includes a first shell and a second shell. The first shell has an open slot, and the second shell closes the opening of the open slot to define the placement cavity. The outer surface of the second shell away from the first shell is formed with a spray port. In this way, the core can be assembled into the open slot through the opening of the open slot, and then the second shell is used to cover the opening of the open slot to complete the assembly of the housing and the core. The assembly is simple and convenient.

[0139] In one embodiment, the core is detachably arranged in the placement cavity, and the second shell detachably covers the opening of the open slot. In this way, when maintenance is required, such as cleaning or replacing the core, the core can be taken out for maintenance, such as cleaning or replacing, without damaging the housing.

[0140] The detachable connection method between the second shell and the first shell is not limited. Exemplarily, the second shell and the first shell are threadedly connected or snap-connected, etc.

[0141] For example, in one embodiment, the first shell, the first joint 22 and the second joint 23 may be an integrally formed structure. In this way, the assembly process can be reduced, and the connection between the first shell and the first joint 22 may not require a seal, and the connection between the first shell and the second joint 23 may not require a seal, which can reduce the use of seals.

[0142] The first joint 22 may be substantially in the shape of a hollow cylinder to facilitate connection with the first pipe 31 .

[0143] The second joint 23 may be substantially in the shape of a hollow cylinder to facilitate connection with the third pipeline 101 .

[0144] Exemplarily, the steam generator 4 can generate steam by heating. In one embodiment, the steam generator 4 includes a shell and a heating element, the shell forms a steam outlet 4a and a liquid inlet 4b, the shell has a heating chamber, the steam outlet 4a and the liquid inlet 4b are both connected to the heating chamber, and at least part of the heating element is located in the heating chamber. The clothing care liquid enters the heating chamber through the liquid inlet 4b, and the heating element heats the clothing care liquid in the heating chamber to generate steam; the steam is discharged to the second fluid inlet 2b through the steam outlet 4a.

[0145] In this embodiment, the high-temperature and high-pressure steam generated in the heating chamber enters the steam delivery device 2, for example, the negative pressure flow channel. The high-speed flowing steam can generate negative pressure in the negative pressure flow channel, so that the clothing care liquid from the first liquid supply path 3 enters the steam delivery device 2, for example, the liquid flow channel. The clothing care liquid from the first liquid supply path 3 can cool the steam in the steam delivery device 2 to avoid the steam temperature being too high. The high-speed steam impacts the clothing care liquid to generate droplets that are sprayed into the barrel assembly 1.

[0146] In one embodiment, please refer to Figure 3 , the steam outlet 4a is formed on the side wall of the shell facing the steam delivery device 2. For example, the steam delivery device 2 is located on the right side of the shell, and the steam outlet 4a is formed on the right side wall of the shell. In this way, the distance between the steam outlet 4a and the steam delivery device 2 is relatively close, and the path of the steam from the steam outlet 4a to the second fluid inlet 2b is relatively short, which can shorten the length of the third pipeline 101 as much as possible and reduce the energy loss during the steam flow process.

[0147] In one embodiment, the liquid inlet 4b may be formed on a side wall of the housing away from the steam delivery device 2. For example, the liquid inlet 4b is formed on a left side wall of the housing.

[0148] In one embodiment, the heating element can convert electrical energy into thermal energy, for example, the heating element can be a resistive heating structure or other types of heating structures.

[0149] In one embodiment, the laundry treatment device includes a circulation air duct. At least one air inlet communicating with the laundry treatment chamber 1a is formed on the rear side wall of the drum 11. The circulation air duct communicates with the air inlet and the air outlet of the laundry treatment chamber 1a. The circulation air duct is used to provide a circulating air flow that repeatedly flows through the laundry treatment chamber 1a. The air flow in the circulation air duct can enter the laundry treatment chamber 1a through the air inlet, and the air flow in the laundry treatment chamber 1a enters the circulation air duct through the air outlet. The air flow can circulate between the circulation air duct and the laundry treatment chamber 1a.

[0150] It can be understood that the number of air inlets can be one or more, for example: two, three, four, five, etc.

[0151] In one embodiment, the base 8 forms a heat exchange channel, and the heat exchange channel is a part of the circulation air duct.

[0152] In one embodiment, the laundry treatment device includes a heat exchange component located in the heat exchange channel. The heat exchange component is used to exchange heat with the air flow in the heat exchange channel, so as to dehumidify and heat. The humid and hot air flow in the laundry treatment chamber 1a enters the heat exchange channel, and after performing heat and mass exchange with the heat exchange component, it is converted into dry and hot air flow, and the dry and hot air flow returns to the laundry treatment chamber 1a through the air inlet.

[0153] In some embodiments, the heat exchange component includes a condenser and an evaporator. The laundry treatment device further includes 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 the refrigerant can circulate in the heat pump system. The air flow in the circulation air duct exchanges heat with the refrigerant in the evaporator and the condenser to form a dry and hot air flow. The evaporator is used to cool and dehumidify the humid and hot air flow from the laundry treatment chamber 1a into a dry and cold air flow; the condenser heats the dry and cold air flow into a dry and hot air flow and returns it to the laundry treatment chamber 1a.

[0154] The working principle of the heat pump system is as follows: The compressor inhales low-pressure gaseous refrigerant and compresses it into high-pressure for discharge; the discharged high-pressure refrigerant enters the condenser, and the refrigerant in the condenser transfers heat to the air flow to condense into a high-pressure liquid; the high-pressure liquid refrigerant flows through the throttling device for throttling and pressure reduction, and then becomes a low-pressure and low-temperature gas-liquid two-phase mixture and enters the evaporator; the refrigerant in the evaporator absorbs the heat of the air flow and becomes low-pressure gaseous; the low-pressure gaseous refrigerant is inhaled by the compressor again; and so on, repeating the cycle to achieve heat exchange. That is to say, the evaporator is used to cool and dehumidify the humid and hot air flow from the laundry treatment chamber 1a to form a dry and cold air flow, the condenser heats the dry and cold air flow into a dry and hot air flow and then returns it to the laundry treatment chamber 1a, and the dry and hot air flow returning to the laundry treatment chamber 1a contacts the wet clothes to form a humid and hot air flow again, completing one drying cycle. By repeatedly running the drying cycle, a circulating air flow is continuously provided to the laundry treatment chamber 1a to dry the clothes.

[0155] Exemplarily, both the evaporator and the condenser can be finned tube heat exchangers.

[0156] Exemplarily, the throttling device includes but is not limited to an electronic expansion valve and the like.

[0157] In one embodiment, the laundry treating device includes a blower wheel for driving the flow of air. Exemplarily, the blower wheel is located in the heat exchange passage. During the process of drying clothes, the blower wheel is used to drive the air flow passing through the clothes to flow through the evaporator and the condenser in sequence, and then blow towards the clothes to form a circulating air flow. The blower wheel can accelerate the air flow and improve the clothes drying efficiency.
