The present application will be further described in detail below with reference to the drawings and specific embodiments. In addition, the terms "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0030] In the embodiments of the present application, "a plurality of" means that the quantity includes two or more. The unit "°C" refers to the temperature unit Celsius.

[0031] The functions of the laundry treatment device provided in 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.

[0032] 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 in a horizontal direction or an inclined direction. The drum assembly 1 has a laundry treatment chamber 1a for placing clothes.

[0033] The axis of the drum assembly 1 extending in the inclined direction means that the axis of the drum assembly 1 intersects obliquely with the horizontal direction.

[0034] In one embodiment, please continue to refer to Figure 1 and Figure 2 , the drum assembly 1 includes a rotatable clothes drum 11, and the clothes drum 11 has a loading and unloading opening facing forward. The clothes drum 11 has a laundry treatment chamber 1a, and the clothes drum 11 can be used to place loads such as clothes. The user puts clothes into or takes clothes out of the clothes drum 11 through the loading and unloading opening from the front. The clothes drum 11 can rotate. During the rotation of the clothes drum 11, the clothes are driven to move from the bottom to the top; under the action of gravity, the clothes fall from the top to the bottom. In this way, the clothes are dispersed, beaten, and their postures are changed under the combined action of the clothes drum 11 and gravity.

[0035] In some embodiments, the clothes drum 11 may be generally in the shape of a hollow cylinder.

[0036] In some embodiments, the drum assembly 1 includes an outer tub, and the clothes drum 11 may be disposed in the outer tub. The outer tub can remain stationary. It can be understood that an outer tub may or may not be provided outside the clothes drum 11.

[0037] In some embodiments, please refer to Figure 1 and Figure 2 , the drum assembly 1 may only have the clothes drum 11 without the above-mentioned outer tub. In this embodiment, the clothes drum 11 may be a single-drum structure. That is to say, the laundry treatment device only has one drum, namely the clothes drum 11.

[0038] 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.

[0039] 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.

[0040] In some embodiments, the laundry treatment device includes a cabinet, and both the drum assembly 1 and the front support 9 are disposed in the cabinet. The cabinet is provided with an opening communicating with the laundry treatment chamber 1a of the drum assembly 1.

[0041] In some embodiments, the cabinet may be generally hexahedral, for example, cubic or cuboid.

[0042] In some embodiments, the laundry treatment device includes a door body for selectively opening or closing the opening of the cabinet.

[0043] Please refer to Figure 1 and Figure 2 , the laundry treatment device includes a laundry treatment 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 path 3, and a second liquid supply path 6.

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

[0045] Please refer to 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 laundry treatment 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 path 3 communicates with the first liquid outlet 5a and conveys fluid to the laundry treatment chamber 1a. The first liquid supply path 3 introduces the laundry care liquid in the liquid storage box 5 into the laundry treatment chamber.

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

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

[0049] 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 extract liquid from the liquid storage box 5.

[0050] In the laundry treatment device provided by the embodiment of the present application, the first liquid supply path 3 transports the laundry care liquid in the liquid storage box 5 to the laundry treatment chamber 1a, and the second liquid supply path 6 transports the laundry care liquid in the liquid storage box 5 to the steam generator 4. The first liquid supply path 3 and the second liquid supply path 6 are both connected to the same liquid storage box 5. In this way, the number of liquid storage boxes 5 can be reduced, the components for dispensing fluids can be reduced, the production cost and assembly difficulty can be reduced, and the production efficiency can be improved.

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

[0052] The laundry care liquid is in a liquid state at room temperature and normal pressure. The room temperature can be from -20°C to 50°C. The normal pressure can be one atmosphere.

[0053] The laundry care liquid includes an aqueous solution and a functional preparation. The functional preparation includes, but is not limited to, detergents, fabric softeners, and / or fragrance enhancers, etc.

[0054] 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, thereby achieving clothes cleaning.

[0055] The steam generator 4 can convert the liquid laundry care liquid into gaseous steam. That is to say, the steam can be gaseous laundry care liquid. Taking the aqueous solution of the laundry care liquid as an example, the steam includes, but is not limited to, water vapor.

[0056] It can be understood that the second liquid supply path 6 and the first liquid supply path 3 can suck the same laundry 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 laundry 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 laundry 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 laundry care liquid. For example, both the second liquid supply path 6 and the first liquid supply path 3 use an aqueous solution. The second liquid supply path 6 and the first liquid supply path 3 can also use different laundry care liquids. For example, the second liquid supply path 6 uses an aqueous solution, and the first liquid supply path 3 uses a detergent or a fragrance enhancer, etc.

[0057] In some embodiments, the liquid storage box 5 has a plurality of mutually isolated chambers. The first liquid outlet 5a communicates with one of the chambers, and the second liquid outlet 5b communicates with another one of the chambers. The mutual isolation of the plurality of chambers means that the plurality of chambers are not connected to each other, and fluid cannot flow between the chambers. The same laundry care liquid or different laundry care liquids can be placed in different chambers. Exemplarily, the chamber communicating with the second liquid outlet 5b contains aqueous liquid, and the chamber communicating with the first liquid outlet 5a contains a functional preparation. With such a design, the steam generator generates steam and discharges it into the laundry treatment chamber 1a, and the second liquid supply path 6 synchronously discharges the functional preparation into the laundry treatment chamber 1a.

[0058] 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. Thus, both the first liquid outlet 5a and the second liquid outlet 5b draw the same kind of laundry care liquid from the liquid storage chamber 5c.

[0059] In one embodiment, please refer to Figures 1 to 5 , the laundry treatment device includes a steam discharging device 2. The steam discharging device 2 has a first fluid inlet 2a and a second fluid inlet 2b. The first liquid supply path 3 connects the first liquid outlet 5a and the first fluid inlet 2a, and the steam outlet 4a communicates with the second fluid inlet 2b. The steam discharging device 2 discharges the fluid from the first fluid inlet 2a and the fluid from the second fluid inlet 2b into the cylinder assembly 1.

[0060] The steam discharging device is a structure for discharging steam, and the steam is in a mist form. Exemplarily, the steam discharging 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 mist form presented after the fluid is dispersed, and the hot steam is a high-temperature mist form generated by heating and evaporation. Exemplarily, the high-temperature mist form 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 flow direction. The power source includes, but is not limited to, electric energy or other energy sources.

[0061] It can be understood that normal temperature refers to a temperature of 20°C to 40°C, and low temperature is lower than 20°C. High temperature refers to a temperature higher than 40°C.

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

[0063] In this embodiment, the steam generated by the steam generator 4 and the fabric care liquid in the first liquid supply path 3 both enter the laundry treatment chamber 1a through the steam dispensing device 2, increasing the water mist content of the steam, improving the ironing and wrinkle removal effects, and having good visualization. Moreover, functional agents can be dispensed by using the steam generator and the steam dispensing device, which can simplify the dispensing path of the functional agents, reduce the components for dispensing the functional agents, and have high integration and reliability and low cost.

[0064] 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 in the steam dispensing device 2 and then sprayed into the cylinder assembly 1.

[0065] In one embodiment, the steam dispensing device 2 includes a nozzle, and the nozzle includes a spray orifice, a negative pressure flow path, and a liquid flow path. The negative pressure flow path communicates with the second fluid inlet 2b and the spray orifice, and the liquid flow path communicates with the first fluid inlet 2a and the negative pressure flow path.

[0066] The spray orifice is used to spray the fluid into the cylinder assembly 1, such as into the laundry treatment chamber 1a.

[0067] The negative pressure flow path communicates with the second fluid inlet 2b and the spray orifice, and the negative pressure flow path allows the passage of steam, such as water vapor.

[0068] The liquid flow path communicates with the first fluid inlet 2a and the negative pressure flow path, and the liquid flow path allows the passage of the fabric care liquid. The negative pressure flow path can generate negative pressure to suck the fabric care liquid in the liquid flow path into the negative pressure flow path. In this way, the spray orifice can spray steam and the fabric care liquid simultaneously.

[0069] The manner of generating negative pressure in the negative pressure flow path is not limited. For example, the cross-sectional area of the negative pressure flow path can be smaller than that of the steam outlet to form negative pressure. Another example is that a vortex structure can be added to the negative pressure flow path, and the vortex structure causes the hot steam to generate vortices and / or flow separation to form negative pressure.

[0070] In one embodiment, the flow-through area of the negative-pressure flow channel is smaller than that of the steam outlet. By reducing the flow-through 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 that at the steam outlet, and the static pressure in the negative-pressure flow channel is less than that at the steam outlet, so that a negative pressure can be generated in the negative-pressure flow channel. The principle of generating negative pressure in the negative-pressure flow channel may include: the steam generator generates hot steam at high temperature and high pressure. 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 hot steam at high temperature and high pressure enters the negative-pressure flow channel through the steam outlet. The dynamic pressure in the negative-pressure flow channel is greater than that at the steam outlet, and the static pressure in the negative-pressure flow channel is less than that 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 up a power driving mechanism such as a pumping mechanism to drive the flow of the hot steam; alternatively, a power driving mechanism such as a pumping mechanism can be added to accelerate the flow rate of the hot steam.

[0071] In one embodiment, an eddy current structure may be provided in the negative-pressure flow channel. The eddy current structure can block the flow of the hot steam to generate eddy currents and / or flow separation, so as to form a negative pressure. The eddy current structure can not only block the steam flow, but also reduce the flow-through area of the negative-pressure flow channel.

[0072] The shape of the eddy current structure is not limited. Exemplarily, the eddy current structure can be in a convex shape, a spiral shape, etc. The eddy current structure can be provided 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.

[0073] The spiral shape means that the eddy current structure is in a spiral line shape. The convex 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.

[0074] In this embodiment, the negative-pressure flow channel can generate a 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 be dispersed into a mist shape, that is, it plays a role in atomizing the clothing care liquid. In this way, both the steam and the mist shape enter the cylindrical body assembly 1 through the injection port. Thus, 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 generated by the negative-pressure flow channel is used to transport the clothing care liquid into the cylindrical body assembly 1, saving the power pumping mechanism, reducing the production cost, and simplifying the structural complexity.

[0075] The power pumping mechanism refers to a mechanism that uses a power source to provide 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.

[0076] It can be understood that the mist form refers to the form in which the fabric care liquid is in the form of granular droplets. Exemplarily, the diameter of the droplets in the mist form can be no more than 50 μm. This is only an example diameter of the mist form.

[0077] Taking steam as water vapor and the fabric care liquid as aqueous liquid as an example, the water vapor impacts the aqueous 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 iron and press the clothes, reducing the wrinkles generated during the drying process of the clothes. During the drying process of the clothes, the hot air flow dries the clothes. If the temperature of the hot air flow is too high, it will cause the drying speed of the clothes to be too fast, resulting in problems such as more wrinkles and deeper creases on the clothes; if the temperature of the hot 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 final stage of drying the clothes, the steam delivery device 2 can spray the water vapor carrying the mist form into the clothes treatment chamber 1a. While the hot air flow dries the clothes, the water vapor carrying the mist form slightly wets the clothes again, humidifying and cooling the clothes to a certain extent by using the water vapor carrying the mist form, achieving the effect of ironing the clothes, and effectively improving problems such as more wrinkles and deeper creases caused by too fast drying.

[0078] 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 mist form 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 mist form, which can not only reduce the usage amount of the dry cleaning agent, but also facilitate the penetration of the dry cleaning agent into the fibers of the clothes. The water vapor can slightly wet the clothes and improve the decontamination efficiency.

[0079] In one embodiment, the negative pressure flow channel includes a Venturi channel and an inhalation channel, and the inhalation channel communicates with the Venturi channel and the liquid flow channel.

[0080] 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 used 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 a mist form.

[0081] 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.

[0082] 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.

[0083] In one embodiment, the Venturi channel includes a converging section and a throat section. Along the flow direction of the steam, the cross-sectional area of the first end of the converging section is larger than that of the second end of the converging section, and the second end of the converging section is connected to the first end of the throat section. Exemplarily, the cross-sectional area of the second end of the converging section is equal to the cross-sectional area of the throat section.

[0084] Here, the steam first flows through the converging section and then through the throat section. Specifically, the steam first flows through the first end of the converging section and then enters the throat section through the second end of the converging section. Since the cross-sectional area of the first end of the converging section is larger than that of the second end of the converging section, the steam is accelerated and decompressed after passing through the converging section and then enters the throat section. The flow velocity of the steam in the throat section is greater than that of the steam at the first end of the converging section, and the air pressure of the steam in the throat section is less than that of the steam in the converging section. The air pressure around the outlet of the throat section is relatively small, generating a negative pressure in the suction channel to drive the clothing care liquid in the liquid flow channel to enter the Venturi channel through the suction channel.

[0085] 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 velocity cluster such as steam or clothing 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-section of the flow.

[0086] In one embodiment, the cross-sectional area of the converging section gradually decreases from the first end to the second end along the steam flow direction. In this way, the flow velocity of the steam gradually increases and the air pressure gradually decreases in the converging section, and the air pressure shows a continuous change trend, which can reduce the turbulence degree of the steam.

[0087] In one embodiment, the cross-sectional area at any position of the throat section remains unchanged. The steam that has been accelerated and depressurized in the converging 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.

[0088] In some embodiments, one end of the suction channel is connected to the Venturi channel downstream of the throat section along the steam flow direction. In this way, the flow velocity is relatively faster and the air pressure is relatively smaller downstream of the throat section along the steam flow direction, so as to generate a larger negative pressure.

[0089] 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 clothing care liquid can be an aqueous solution. Tap water can be used to provide the aqueous solution to the liquid storage box 5.

[0090] In one embodiment, the clothing treatment device includes a liquid pump, and the liquid pump is arranged on the second liquid supply path 6 to pump the clothing care liquid in the liquid storage box 5 into the steam generator 4.

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

[0092] In one embodiment, please refer to Figure 2 , Figure 4 and Figure 6 , the laundry treating apparatus includes a liquid injection box 7, the liquid storage box 5 has a liquid inlet 5g, and the discharge port of the liquid injection box 7 communicates with the liquid inlet 5g of the liquid storage box 5.

Another example is that both the steam generator 4 and the steam delivery device 2 are located on the right side of the center line extending in the up and down direction of the front support 9. Designed in this way, the distance between the steam generator 4 and the steam delivery device 2 is relatively close, so that the steam can enter the steam delivery device 2 more quickly, reducing the energy loss during the steam flow process.

[0115] 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 one embodiment, please refer to Figure 1 and Figure 4 , the first liquid supply path 3 and the second liquid supply path 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, avoiding interference between the first liquid supply path 3 and the second liquid supply path 6 and the cylindrical component 1.

[0128] In one embodiment, please refer to Figures 3 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 the first fluid inlet 2a, the second joint 23 forms the second fluid inlet 2b. The main body 21 is located at the rear side of the front support 9. 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.

[0129] 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.

[0130] In this embodiment, the main body 21 is located at the rear side of the front support 9 so as to facilitate the injection of steam and the laundry treating liquid into the laundry treating 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 there will be no interference from the cylinder assembly 1, so as to facilitate the connection of the first joint 22 to the first pipe 31 and the second joint 23 to the third pipe 101. The assembly operation is convenient, and it can also prevent the first pipe 31 and the third pipe 101 from entering between the front support 9 and the cylinder assembly 1, causing interference.

[0131] In one embodiment, the main body 21 includes a housing and a core body. The housing is formed with a placement cavity and a jet orifice. The core body is accommodated in the placement cavity. The core body is formed with a Venturi channel and a suction channel. Both the first connector 22 and the second connector 23 are connected to the housing. 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] Exemplarily, the Venturi channel may extend along the length direction of the core body. One end of the suction channel communicates with the Venturi channel, and the other end of the suction channel may penetrate through the circumferential surface of the core body.

[0133] It can be understood that the circumferential surface of the core body refers to the outer surface surrounding the length direction of the core body.

[0134] In this embodiment, the steam from the second fluid inlet 2b sequentially flows through the air inlet section, the Venturi channel, and the jet orifice; the clothing care liquid from the first fluid inlet 2a sequentially flows through the liquid inlet section, the placement cavity, the suction channel, and the jet orifice.

[0135] Exemplarily, the housing and the core body can be independently manufactured to reduce the manufacturing difficulty. Accommodating the core body in the placement cavity makes the overall structure of the steam delivery device 2 compact and the overall size smaller.

[0136] 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. A jet orifice is formed on the outer surface of the second shell away from the first shell. In this way, the core body 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 body. The assembly is simple and convenient.

[0137] In one embodiment, the core body is detachably disposed in the placement cavity, and the second shell detachably covers the opening of the open slot. In this way, when maintenance such as cleaning or replacing the core body is required, the core body can be taken out for maintenance such as cleaning or replacing without damaging the housing.

[0138] The detachable connection manner 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.

[0139] Exemplarily, in one embodiment, the first shell, the first connector 22, and the second connector 23 may be an integrally formed structure. In this way, the assembly process can be reduced. Sealing members may not be used at the connection between the first shell and the first connector 22, and sealing members may not be used at the connection between the first shell and the second connector 23, which can reduce the use of sealing members.

[0140] The first connector 22 may be generally in the shape of a hollow cylinder to facilitate connection to the first pipe 31.

[0141] The second joint 23 may be substantially in the shape of a hollow cylinder to facilitate connection with the third pipeline 101 .

[0142] 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.

[0143] 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.

[0144] In one embodiment, please refer to Figure 2 , Figure 3 and Figure 5 , 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.

[0145] 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.

[0146] 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.

[0147] In one embodiment, the clothing processing device includes a circulating air duct, and the rear side wall of the clothing drum 11 is formed with at least one air inlet connected to the clothing processing chamber 1a, and the circulating air duct connects the air inlet and the air outlet of the clothing processing chamber 1a. The circulating air duct is used to provide a circulating airflow that repeatedly flows through the clothing processing chamber 1a. The airflow of the circulating air duct can enter the clothing processing chamber 1a through the air inlet, and the airflow in the clothing processing chamber 1a enters the circulating air duct through the air outlet. The airflow can circulate between the circulating air duct and the clothing processing chamber 1a.

[0148] It can be understood that the number of air inlets can be one or more, for example: two, three, four, five, etc.

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

[0150] 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.

[0151] 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, condenser, throttling device and evaporator are connected by pipes to form a heat pump system, and the refrigerant can circulate in the heat pump system. The air flow in the circulating air duct exchanges heat with the refrigerant in the evaporator and condenser to form 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 dry and cold air flow; the condenser heats the dry and cold air flow into dry and hot air flow and returns it to the laundry treatment chamber 1a.

[0152] The working principle of the heat pump system is as follows: the compressor sucks in low-pressure gaseous refrigerant and compresses it into high-pressure 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 high-pressure liquid; the high-pressure liquid refrigerant flows through the throttling device for throttling and depressurization, 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 sucked in by the compressor again; and so on in a 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 dry and cold air flow, the condenser heats the dry and cold air flow into 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 humid and hot air flow again, completing one drying cycle. By repeatedly running the drying cycle, circulating air flow is continuously provided to the laundry treatment chamber 1a to dry the clothes.

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

[0154] Exemplarily, the throttling device includes but is not limited to an electronic expansion valve, etc.

[0155] In one embodiment, the laundry treatment device includes a blower wheel for driving the flow of air. Exemplarily, the blower wheel is located in the heat exchange channel. 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, which can accelerate the air flow and improve the clothes drying efficiency.
