Illustratively, the door 32 is attached to the front plate 311.

Referring to fig. 4, 5 and 6, the foam dispensing module 100 has a receiving chamber 111c, and the receiving chamber 111c is used for receiving a mixed solution formed by mixing a cleaning medium and a dissolution medium. The foam dispensing module 100 is used to generate foam from the mixed liquor.

The type of the dissolution medium is not limited, and may be, for example, water, an organic solvent, or the like.

In the embodiments of the present application, the dissolution medium is described by taking water as an example.

The foam delivery module 100 has a foam outlet 100a, and the foam generated by the foam delivery module 100 exits the foam delivery module 100 through the foam outlet 100 a.

In some embodiments, the mixed liquid may be directly injected into the accommodating chamber 111c, or the dissolution medium (e.g., water) and the cleaning medium may be injected into the accommodating chamber 111c, respectively, and the dissolution medium and the cleaning medium may be mixed in the accommodating chamber 111c to obtain the mixed liquid.

The foam passage communicates the foam outlet 100a with the laundry treating chamber 300a for injecting foam into the laundry treating chamber 300 a. Specifically, the inlet end of the foam passage is connected to the foam outlet 100a, and the outlet end of the foam passage extends into the laundry access opening, thereby injecting the foam into the laundry treatment chamber 300 a.

Foam channels refer to the entire path for transporting foam.

The laundry treating apparatus is capable of cleaning laundry using foam and in a non-soaking manner. Wherein, the non-soaking mode refers to no liquid water soaking.

The laundry treating apparatus cleans laundry using foam and in a non-soaking manner, that is, the foam enters the laundry treating chamber 300a, and the laundry is cleaned by means of a cleaning medium carried by the foam, and the laundry is not soaked in water during this process.

Since the laundry is cleaned by non-soaking, it is unnecessary to soak the laundry with water, a large amount of foam can be injected into the laundry treating chamber 300a, for example, the laundry treating drum 300 is rotated while the foam is introduced into the laundry treating chamber 300a, so that the foam and the laundry can be promoted to be sufficiently contacted, the laundry can be contacted with the foam in a large area, the cleaning capability is improved, the laundry treating efficiency is improved, and some laundry which cannot be soaked and washed with water can be cleaned. After the foam cleaning is finished, the water content of the clothes is not high, and after the foam cleaning is finished, drying treatment is carried out, so that drying time can be saved, and drying efficiency is improved. The foam cleaning process requires substantially no water discharge, and thus, can be applied to a laundry treatment apparatus requiring no washing water. Of course, the present invention may be applied to a washing machine or the like, and the washing machine is not required to inject washing water for soaking laundry into the laundry treatment chamber 300a during the foam cleaning.

The specific type of cleaning medium is not limited, and may be, for example, a dry cleaning agent, a laundry detergent, etc., and is not limited herein.

The specific type of laundry treatment apparatus is not limited, and includes, for example, but is not limited to: washing machines, dryers, washing and drying machines, and the like.

Among them, the laundry drying apparatus means a laundry drying apparatus having a laundry drying function, but not having a water soaking washing function. The washing and drying integrated machine has the functions of soaking and washing clothes in water and drying the clothes.

The manner in which the foam dispensing module 100 foams the mixed liquid is not limited.

Referring to fig. 3 and 4, for example, the foam dispensing module 100 includes a foam pump 112, and the foam pump 112 pumps the mixed liquid in the accommodating chamber 111c and foams the mixed liquid into foam inside the foam pump 112, and the foam is discharged from the foam outlet 100 a. Referring to fig. 6, the dashed lines and arrows in fig. 6 illustrate the flow path of the mixed liquor pumped by the foam pump 112.

The specific structure of the foam pump 112 is not limited, and any foam pump 112 in the prior art may be employed.

Illustratively, the foam dispensing module 100 has an overflow channel for receiving and directing fluid that overflows the receiving cavity 111 c.

The fluid guided out of the overflow passage may be discharged from the drain passage of the laundry treating apparatus.

Illustratively, the foam dispensing module 100 includes a housing assembly 111, with a portion of the interior space of the housing assembly 111 defining the receiving cavity 111c and a portion defining the overflow channel.

In this embodiment, when the amount of the mixed solution in the accommodating cavity 111c exceeds the upper limit value, the excessive mixed solution can be led out from the overflow channel, so that the mixed solution in the accommodating cavity 111c is prevented from leaking and wetting other parts, and the electrical safety of the clothes treating apparatus is improved.

Illustratively, in some embodiments, the circumferential side wall of the laundry treatment drum 300 may be a continuous wall through which the fluid medium cannot pass, i.e. the laundry treatment drum 300 is a non-porous inner drum. During the rotation of the laundry treating drum 300, the bubbles in the laundry treating drum 300 do not directly pass through the laundry treating drum 300, and thus, the bubbles are prevented from flowing to the outside of the laundry treating drum 300, and the bubbles can be effectively left in the laundry treating drum 300, thereby securing the cleaning effect of the bubbles on the laundry.

It is understood that the imperforate inner tub means that the circumferential sidewall of the laundry treating tub 300 in the radial direction may be free of any hole; there may be a small number of holes and the holes may be in a closed state during foam cleaning of the laundry, for example, to facilitate closing of the holes by a valve so that the foam does not pass through the holes to the outside of the laundry treating drum 300.

The laundry treating apparatus may be provided with or without a drain pipe as a whole. For example, some condensing clothes drying apparatuses have a drain pipe for discharging condensing water for condensing and cooling hot air flow. The heat pump type clothes drying apparatus may be provided with a drain pipe for discharging condensed water condensed from the hot and humid air flow, or may collect the condensed water without providing a drain pipe. For another example, the washing machine itself is provided with a drain pipe.

In some embodiments, the overflow channel is capable of receiving not only fluid that overflows the receiving cavity 111c, but also fluid from other locations of the foam dispensing module 100.

In some embodiments, referring to fig. 7, a filling port 31b is provided on the case 31; the filling port 31b communicates with the accommodating chamber 111c, and a user can manually fill the cleaning medium, the dissolution medium, or the mixed solution from the filling port 31b into the accommodating chamber 111c.

Illustratively, referring to fig. 3, the foam dispensing module 100 includes a liquid pump 113 for detachably interfacing with the container 200 to pump the cleaning medium, dissolution medium, or mixture stored in the container 200 to the receiving chamber 111c. When the container 200 is used for containing the cleaning medium, the liquid pump 113 pumps the cleaning medium. When the container 200 is used for containing the mixed liquid, the liquid pump 113 pumps the mixed liquid. When the container 200 is used to hold a dissolution medium, the liquid pump 113 pumps the dissolution medium.

The liquid pump 113 can quantitatively pump the cleaning medium, the dissolving medium or the mixed liquid in the container 200, so that the flow rate can be quantitatively controlled, and the consistency of the foam can be improved.

The specific structure of the liquid pump 113 is not limited, and any liquid pump 113 in the prior art may be used.

Referring to fig. 5, the foam dispensing module 100 has a flow guide channel 111f, and the housing assembly 111 itself is structured to form the flow guide channel 111f. One end of the diversion channel 111f is positioned below the butt joint 113a of the liquid pump 113, and the other end is communicated with the overflow channel, so as to divert the fluid leaked at the butt joint 113a to the overflow channel.

The docking port 113a refers to a portion where the liquid pump 113 is used to dock with the container 200, and a portion where the liquid pump 113 is used to dock with the side wall of the housing chamber 111 c. The liquid pump 113 may leak the interface during the process of pumping the cleaning medium, the dissolution medium or the mixed liquid, and thus the flow guide channel 111f may guide the leaked cleaning medium, dissolution medium or mixed liquid to the overflow channel, and intensively discharge through the overflow channel.

Illustratively, referring to fig. 5, the foam delivery module 100 has a drawing space 111a, and the laundry treating apparatus includes a drawing box for accommodating the container 200, in which the container 200 is detachably placed. The drawing box is drawably disposed in the drawing space 111 a. The foam delivery module 100 provides accommodation space and mounting support for the drawer, so that the inner wall of the box 31 does not need to be specially provided with a mounting structure for the drawer, and the structural requirement on the box 31 is reduced.

In this embodiment, referring to fig. 1, the case 31 has an opening 31a, and the drawer can be at least partially drawn out of the case 31 through the opening 31 a.

When the container 200 needs to be replaced, the drawing box is drawn out, the container 200 in the drawing box is taken out, and the replaced container 200 is put into the drawing box. In this manner, the user may conveniently access the container 200.

In some embodiments, the container 200 may be a single use device. After the cleaning medium, dissolving medium or mixed liquor stored in the container 200 is used up, the old container 200 may be taken out and replaced with a new container 200.

In other embodiments, the container 200 may be reusable. After the cleaning medium, the dissolving medium or the mixed solution in the container 200 is used up, a user can pour the cleaning medium, the dissolving medium or the mixed solution into the container 200, and the container 200 can be reused, so that the energy-saving and environment-friendly effects are achieved.

Illustratively, the drawing space 111a and the accommodating chamber 111c are isolated from each other, that is, they are not in a housing relationship, the drawing space 111a is not disposed in the accommodating chamber 111c, and the accommodating chamber 111c is not disposed in the drawing space 111 a.

With continued reference to fig. 5, the drawing space 111a is located above the top wall of the accommodating chamber 111 c. So that the space in the height direction can be fully utilized, and the foam delivery module 100 is compact.

Illustratively, the drawing space 111a is substantially rectangular in shape, and the drawing box is also substantially rectangular in shape, and can accommodate the bottle-shaped container 200.

For example, referring to fig. 4 and 5, the foam dispensing module 100 has an installation space 111g, the liquid pump 113 is disposed in the installation space 111g, and the installation space 111g is located at a rear side of the drawing space 111a in the front-rear direction of the laundry treating apparatus. On the one hand, the rear side of the drawing space 111a has enough space to install the liquid pump 113, and on the other hand, the liquid pump 113 is located at the rear side of the drawing space 111a, so that the liquid pump 113 and the container 200 are conveniently butted in the front-rear direction. Specifically, after the drawer is pushed into the drawing space 111a from the opening 31a, the container 200 within the drawer is docked with the liquid pump 113, and when the drawer is drawn out, the container 200 is separated from the liquid pump 113.

For example, referring to fig. 5, the foam dispensing module 100 has a liquid collecting chamber 111d and a partition wall 1111, the partition wall 1111 being disposed between the liquid collecting chamber 111d and the receiving chamber 111c, that is, the liquid collecting chamber 111d and the receiving chamber 111c are located at opposite sides of the partition wall 1111. The side wall or bottom wall of the liquid collection chamber 111d is provided with an outlet 111d ", and the fluid collected in the liquid collection chamber 111d is discharged from the outlet 111 d". The plenum 111d and the outlet 111d "define the overflow channel described above.

The partition wall 1111 is provided with an overflow port 1111a, and the fluid in the housing chamber 111c overflows to the liquid collecting chamber 111d through the overflow port 1111 a. The height of the overflow 1111a determines the theoretical maximum level of the receiving chamber 111c, and when the actual level in the receiving chamber 111c reaches the height of the overflow 1111a, if fluid (which may be water, cleaning medium, or a mixture) is still continuously being fed into the receiving chamber 111c, excess fluid overflows from the overflow 1111 a.

In this embodiment, the accommodating chamber 111c and the liquid collecting chamber 111d are disposed adjacently, enabling the foam delivery module 100 to be compact.

For example, referring to fig. 5, the liquid pump 113 is disposed above the top wall of the liquid collection chamber 111d. That is, the installation space 111g is located above the top wall of the liquid collection chamber 111d. The liquid pump 113 is not provided in the liquid collection chamber 111d.

In this embodiment, the space above the liquid collection chamber 111d can be fully utilized to install the liquid pump 113, so that the foam dispensing module 100 is compact.

Illustratively, the sump 111d is located at a rear side of the accommodation chamber 111c in the front-rear direction of the laundry treating apparatus. In this embodiment, the liquid collecting chamber 111d is located at the rear side, and the space at the rear side of the accommodating chamber 111c is fully utilized, so that the overflowed fluid is also easily discharged from the rear.

For example, referring to fig. 4 and 5, the laundry treating apparatus includes a water inlet valve 13, the water inlet valve 13 for filling water into the accommodating chamber 111 c. Specifically, the foam dispensing module 100 has a water inlet 100b, a water inlet valve 13 is connected to the water inlet 100b through a water inlet pipe 14, and water and a cleaning medium are mixed in a receiving chamber 111c to generate a mixed solution.

In this embodiment, since the cleaning medium and water are diluted and mixed in the foam dispensing module 100, the concentration of the cleaning medium in the container 200 can be relatively high, and thus, the volume of the container 200 can be reduced.

For example, referring to fig. 5, the water inlet valve 13 is disposed within the liquid collection chamber 111 d. Thus, when water leakage occurs at the junction of the water inlet valve 13 and the water inlet pipe 14, the leaked water may enter the liquid collecting chamber 111d and be discharged through the outlet 111d″ of the liquid collecting chamber 111 d.

Illustratively, the laundry treating apparatus includes a control unit for monitoring the liquid level in the accommodating chamber 111c, and a liquid level detecting unit for controlling the water inlet valve 13 to be opened or closed according to a monitoring signal of the liquid level detecting unit.

It should be noted that, the liquid level detection unit may send out a monitoring signal when the liquid level of the accommodating cavity 111c reaches the designed liquid level value, or may monitor in real time and periodically send out a monitoring signal representing the current liquid level of the accommodating cavity 111 c.

For example, when the liquid level of the accommodating chamber 111c reaches a designed liquid level value during water filling, the liquid level detection unit sends out a monitoring signal, and the control unit controls the water inlet valve 13 to be closed so as to stop water filling into the accommodating chamber 111 c. If the liquid level of the accommodating chamber 111c does not reach the designed liquid level value, the liquid level detection unit may not send out a monitoring signal, and the control unit may control the water inlet valve 13 to continue water inlet. Of course, when the water injection amount of the water inlet valve 13 reaches the current required flow rate, the control unit may control the water inlet valve 13 to be closed to stop the water injection into the accommodating chamber 111c even if the liquid level does not reach the designed liquid level value.

Even if the water inlet valve 13 continuously injects water into the accommodating cavity 111c due to failure, the excessive liquid in the accommodating cavity 111c can overflow to the overflow channel, and then is discharged from the overflow channel, thereby improving safety.

The specific structural form of the liquid level detection unit is not limited, and any technology capable of realizing liquid level monitoring in the prior art can be adopted.

Illustratively, the liquid level detection unit includes a float 17 (refer to fig. 5) and a sensor, the float 17 being disposed in the accommodation chamber 111c, the float 17 being configured to trigger the sensor to generate a monitoring signal when floating to a preset height. The sensor and the control unit perform information interaction, which can be wireless communication interaction or wired communication interaction.

The float 17 floats on the liquid surface and floats up and down along with the change of the height of the liquid surface, and when the liquid level reaches a designed liquid level value, the height of the float 17 just can trigger the sensor to generate a monitoring signal.

It should be noted that the control unit may be a relatively independent circuit board assembly disposed in the foam dispensing module 100, or may be a main control board of the whole machine of the laundry treatment apparatus, which is not limited herein.

The source of the water inlet valve 13 is not limited, for example, a tap water pipe can be connected to the water inlet valve, and the water can be connected to a condensed water box of the clothes treatment device, wherein the water in the condensed water box comes from condensed water collected after the clothes treatment device condenses the hot and humid air flow in the clothes drying process; but also can be water filled by an access user, etc., without limitation.

Of course, in other embodiments, the user may manually add the desired water to the foam delivery module 100, i.e., without the need to feed water through the fill valve 13, but by the user himself.

Illustratively, the foam dispensing module 100 is a preassembled unit, and the preassembled unit is assembled in the cabinet 31 on a production line of the laundry treating apparatus, so that the assembly efficiency can be improved.

Illustratively, the laundry treatment apparatus comprises an electrical structure, wherein the electrical structure comprises at least one of a motor, a compressor, a circuit board.

In a planar projection perpendicular to the height direction of the laundry treating apparatus, the foam delivery module 100 and the electrical structure are disposed at opposite sides of the drum assembly, for example, the foam delivery module 100 is located at the left side of the drum assembly and the electrical structure is located at the right side of the drum assembly; alternatively, the foam delivery module 100 is located on the right side of the cartridge assembly and the electrical structure is located on the left side of the cartridge assembly.

In this embodiment, since the foam delivery module 100 and the electrical structure are disposed at opposite sides of the drum assembly, even though the foam delivery module 100 or the water inlet assembly generates leakage, the leakage does not drop onto the electrical structure, thereby improving the waterproof safety of the laundry treating apparatus. It should be noted that the motor is used to directly or indirectly drive the laundry treating drum 300 to rotate. The compressor is a compressor of a heat pump system for compressing a refrigerant. The circuit board can be a main control board of the whole machine, a variable frequency control board for controlling the compressor, and other types of circuit boards.

It should be noted that, the foam dispensing module 100 and the electrical structure are disposed on two opposite sides of the barrel assembly, including various situations: the foam delivery module 100 and motor are located on opposite sides of the cartridge assembly; and/or the foam delivery module 100 and the compressor are located on opposite sides of the cartridge assembly; and/or the foam delivery module 100 and the circuit board are located on opposite sides of the cartridge assembly. That is, even if the electrical structure includes multiple components, it is not necessary that the foam delivery module 100 and all of the components of the electrical structure be located on opposite sides of the cartridge assembly. For example, where the electrical structure includes a compressor and a motor, in one embodiment: the motor and foam delivery module 100 are located on opposite sides of the barrel assembly, and the compressor and foam delivery module 100 are located on the same side of the barrel assembly; in another embodiment: the motor and compressor are located on the same side of the cartridge assembly, both on opposite sides of the cartridge assembly as the foam delivery module 100.

For example, referring to fig. 1 and 2 by taking a dryer as an example, the laundry treating apparatus includes a front support 500, and the front support 500 is disposed at a front side of the laundry treating drum 300.

For example, referring to fig. 2, the front support 500 has a through-hole 500b, and the through-hole 500b penetrates the front support 500. The inlet end of the foam passage is connected to the foam outlet 100a, and the outlet end of the foam passage passes through the through-hole 500b and extends into the laundry pick-and-place opening to deliver the foam to the laundry treating chamber 300a. In this embodiment, the front support 500 is utilized to provide a mounting location for the foam channel to facilitate the introduction of foam into the laundry treatment chamber 300a. Specifically, since the laundry treating drum 300 needs to be rotated, the front support 500 is not rotated, and the foam passage passes through the through-opening 500b of the front support 500, both to guide the foam to the laundry treating chamber 300a and to avoid interference with the laundry treating drum 300.

Illustratively, taking a washing machine as an example, the laundry treating apparatus includes a front door and a door gasket provided on the front door for sealing a space between the laundry taking-and-putting port and the door body 32, such that the laundry treating chamber 300a becomes a relatively sealed space when the door body 32 is closed, without water leakage. In this embodiment, the front door and/or door seal is provided with a through-opening 500b, and the outlet end of the foam channel passes through the through-opening 500b.

Illustratively, the through-penetration 500b penetrates the front support 500 in a generally fore-aft direction.

For example, referring to fig. 2, the laundry treating apparatus includes a pipe 15, one end of the pipe 15 is connected to the foam outlet 100a, a space within the pipe 15 defines at least a portion of a foam passage, and one end of the pipe 15 remote from the foam outlet 100a extends to a front side of the laundry taking-in/putting-out opening or extends into the laundry taking-out opening. Foam is guided by the pipe 15 to facilitate bending according to the desired foam path, improving flexibility of placement.

Illustratively, the conduit 15 is located on a front side of the front support 500, that is, the conduit 15 and the barrel assembly are located on opposite sides of the front support 500 in the front-to-rear direction. Specifically, the duct 15 is located in the spaced area between the front support 500 and the front plate 311. The pipe 15 and the foam outlet 100a are both located on the front side of the front support 500, and the pipe 15 hardly affects the arrangement of the cartridge assembly, and also makes full use of the space area on the front side of the front support 500.

The pipeline 15 may be an integrated pipeline, and may be formed by connecting multiple sections of pipelines, which is not limited herein.

In some embodiments, the end of the conduit 15 serves as the outlet for the foam channel, that is, in this embodiment, the conduit 15 independently defines the foam channel.

Illustratively, in the laundry treating apparatus having the front support 500, the second end of the pipe 15 passes through the through-hole 500b and protrudes into the laundry taking-in-putting hole, and the foam is discharged from the end of the pipe 15 and is put into the laundry treating chamber 300a.

In other embodiments, referring to fig. 2, the laundry treating apparatus includes a spray head 16, a pipe 15 connecting the foam outlet 100a and the spray head 16, i.e. the spray head 16 is connected to an end of the pipe 15 remote from the foam outlet 100a, and a space in the pipe 15 and a space in the spray head 16 define a foam channel together.

In this embodiment, the foam is put into the laundry treating chamber 300a through the spray head 16, and the foam has an initial velocity, so that the foam is not only convenient to be fully dispersed, so that the contact area between the foam and the laundry in the laundry treating chamber 300a is larger, but also the discharge of the foam generated by the foam putting module 100 can be accelerated, and the efficiency is improved.

Illustratively, in the laundry treating apparatus having the front support 500, the spray head 16 passes through the through-hole 500b and protrudes into the laundry access opening.

Illustratively, the location of the foam outlet 100a is not lower than the location of the through-penetration 500 b. In this embodiment, the resistance to conveying the foam from the foam outlet 100a to the end of the foam passage is smaller, improving the smoothness of the foam conveyance.

For example, referring to fig. 2, the front support 500 has a communication port 500a, the communication port 500a communicates with the laundry taking and putting port, and the communication port 500a surrounds the laundry taking and putting port. During the laundry taking and putting process, laundry may pass through the communication port 500a.

The communication port 500a is smaller than the laundry taking/putting port.

The location of the through-hole 500b is not limited as long as it is capable of facilitating the passage of the foam.

For example, the through-hole 500b is provided at the left side, the right side, the upper left side, the upper right side, the right upper side, and the like of the communication port 500a.

Referring to fig. 2, illustratively, the through-hole 500b is disposed in an upper area of the communication port 500a, on one hand, the position of the outlet end of the foam channel is relatively high, and the foam is put into the laundry treating chamber 300a from above, so that the foam can drop in a parabolic manner under the action of the initial velocity and gravity, so that the foam is more dispersed, the foam can cover a larger range in the laundry treating chamber 300a, and the foam and the laundry can be fully contacted, thereby improving the cleaning effect, and on the other hand, the probability of blocking the outlet of the foam channel by the laundry can be reduced.

The upper region of the communication port 500a refers to a region located higher than the communication hole.

Illustratively, the foam delivery module 100 is connected to at least one of the cabinet 31, the front support 500, or the front door. In this embodiment, there is no need to install the foam delivery module 100 through a cartridge assembly. Illustratively, the front support 500 may be a structure belonging to a dryer, and the front door may be a structure belonging to a washing machine. That is, for the dryer, the foam delivery module 100 may be connected to the cabinet 31 and/or the front support 500. For a washing machine, the foam delivery module 100 may be connected to the cabinet 31 and/or the front door.

Illustratively, referring to fig. 3, in a plane perpendicular to the height direction of the laundry treating apparatus, the foam delivery module 100 is located at a first side of the axis L1 of the drum assembly, and the foam outlet 100a is located on a side wall of the foam delivery module 100 facing the axis L1.

For example, referring to fig. 3, in some embodiments, in a plane perpendicular to a height direction of the laundry treating apparatus, the entirety of the foam delivery module 100 is located at the left side of the axis, and the foam outlet 100a is provided on the right side wall of the foam delivery module 100. In other embodiments, the entirety of the foam delivery module 100 is located on the right side of the axis in a plane perpendicular to the height direction of the laundry treating apparatus, and then the foam outlet 100a is provided on the left side wall of the foam delivery module 100.

In this embodiment, the position of the foam outlet 100a facilitates the connection between the foam outlet 100a and the foam channel, and can be closer to the laundry pick-and-place opening, further shortening the length of the foam channel.

In the present embodiment, the axis L1 of the drum assembly refers to the rotation axis of the laundry treating drum 300.

Illustratively, the foam delivery module 100 is positioned no lower than the center of the laundry access opening, that is, no lower than the axis of the cartridge assembly. Any portion of the foam delivery module 100 is not below the axis of the cartridge assembly. For example, the foam delivery module 100 is disposed at the upper left or upper right of the laundry treating drum 300.

In this embodiment, the center of the laundry access opening is located on the axis L1 of the drum assembly.

The height of the foam delivery module 100 is positioned so that a user can fill the foam delivery module 100 with a cleaning medium with little bending over, and in addition, there is a large space for installing the foam delivery module 100.

Illustratively, in some embodiments, the laundry treating apparatus is of a single-drum structure, i.e., only one drum, only the laundry treating drum 300 described above, and the outside of the laundry treating drum 300 described above has no outer tub. In other embodiments, the outside of the laundry treating drum 300 is further provided with an outer tub.

In some embodiments, the cartridge assembly is a single cartridge structure, referring to fig. 6, the foam delivery module 100 has an arcuate outer surface 111b, and the arcuate outer surface 111b is configured to avoid the outer surface of the cartridge assembly and is spaced apart from the outer surface. I.e. the two are not in contact. When the cylinder assembly moves or rotates, the cylinder assembly and the foam delivery module do not interfere, and in addition, vibration of the cylinder assembly does not directly act on the foam delivery module 100, so that the influence of the vibration on the foam delivery module 100 is reduced. In addition, the foam delivery module 100 is arranged to be attached to the barrel assembly as much as possible by utilizing the adaptation of the arc-shaped outer surface 111b and the outer surface of the barrel assembly, so that the installation space 111g can be fully utilized without interference; in addition, in the laundry treating apparatus having the front support 500, the arc-shaped outer surface 111b also facilitates connection of the foam delivery module 100 with the front support 500.

Illustratively, the foam outlet 100a is positioned no lower than the top edge of the garment access opening. That is, the position of the foam outlet 100a is relatively high, so that the foam flows from the foam outlet 100a to the laundry taking-in/out opening through the foam passage.

Illustratively, the outlet of the foam channel is positioned no lower than the center of the laundry access opening. Thus, the foam is put into the laundry treatment chamber 300a from a relatively high position, and thus, the foam can drop in a parabolic manner under the action of the initial speed and gravity, so that the foam is more dispersed, the foam can cover a larger range in the laundry treatment chamber 300a, the foam and the laundry are convenient to fully contact, and the cleaning effect is improved, and on the other hand, the probability that the laundry blocks the outlet of the foam channel can be reduced.

Illustratively, the laundry treating apparatus includes an air duct in communication with the laundry treating chamber 300a for providing an air flow to the laundry treating chamber 300a. It is understood that the interior of the air duct has a heating element for heating the air flow. When the heating member heats, the air duct provides a hot air flow into the laundry treating chamber 300a to dry laundry by the hot air flow. For example, after the foam is used for cleaning the clothes, the hot air flow is used for drying the clothes and taking away the solvent and the moisture in the foam, so that the effects of removing the foam and drying the clothes are achieved.

Illustratively, the laundry treating apparatus includes a condensation dehumidifying member for condensing and dehumidifying the air flow discharged from the laundry treating chamber 300a. Specifically, the hot dry air flow in the air duct flows to the laundry treating chamber 300a, and during the process of flowing through the laundry treating chamber 300a, the hot dry air flow exchanges heat with laundry and takes away a part of water vapor to form a hot humid air flow, and the hot humid air flow is discharged from the laundry treating chamber 300a to contact with the condensation dehumidifying element, and as the water vapor in the hot humid air flow is separated out due to temperature reduction, the air flow condensed and dehumidified by the condensation dehumidifying element and the low-temperature dry air flow.

In some embodiments, the air flow discharged from the laundry treating chamber 300a flows to the outside environment, i.e., the discharged air flow does not circulate into the laundry treating chamber 300a. It will be appreciated that in the embodiment where the condensation dehumidifying member is not provided, the air flow discharged from the laundry treating chamber 300a directly flows to the external environment without condensation dehumidifying of the condensation dehumidifying member, that is, the air flow flowing to the external environment is a wet and hot air flow, which affects the temperature and humidity of the external environment. In the embodiment provided with the condensation dehumidifying member, the air flow discharged from the laundry treating chamber 300a is dehumidified by condensation of the condensation dehumidifying member, so that the air flow flowing to the external environment and the low-temperature drying air flow are reduced, the influence on the humidity and temperature of the external environment can be reduced, and the contamination of foreign matters such as flocks entrained in the air flow to the external environment can be reduced.

In other embodiments, two ends of the air duct are respectively connected to the laundry treating chamber 300a to form a circulating air flow channel, and the air flow can circulate in the laundry treating chamber 300a and the air duct, so that on one hand, heat energy can be fully utilized, and on the other hand, adverse effects on the environment caused by direct discharge of the air flow to the external environment can be avoided.

The heating member and the condensation dehumidifying member are disposed in the air duct, and the heating member is disposed downstream of the condensation dehumidifying member in the air flow direction, that is, the hot and humid air flowing out of the laundry treating chamber 300a flows through the condensation dehumidifying member and then through the heating member. The condensing and dehumidifying piece is used for condensing and dehumidifying the air flow, and the heating piece is used for heating the air flow.

The working process and the clothes drying principle of the clothes treatment equipment of the embodiment of the application are as follows: the drying hot air flow enters the clothes treatment cavity 300a from the downstream of the air duct along the air flow direction, in the clothes treatment cavity 300a, the drying hot air flow flows through the surface of wet clothes to perform heat-moisture exchange with the wet clothes, moisture in the clothes is absorbed, the moisture in the clothes is changed into wet hot air flow, the wet hot air flow enters the upstream of the air duct and sequentially flows through the condensation dehumidifying part and the heating part, in the process of flowing through the condensation dehumidifying part, water vapor in the wet hot air flow is separated from the air flow due to temperature reduction and is condensed into water drops, the wet hot air flow is condensed and dehumidified by the condensation dehumidifying part to form low-temperature drying air flow, the low-temperature drying air flow is heated into drying hot air flow when passing through the heating part, and the drying hot air flow enters the clothes treatment cavity 300a from the downstream of the air duct again, so that the circulation operation is realized, and continuous drying of the clothes is realized.

The low-temperature dry air flow is a flow of wet hot air, and the low-temperature dry air flow has a lower temperature than the wet hot air flow. The low temperature in the embodiments of the present application may be room temperature.

The specific types of the condensation dehumidifying member and the heating member described above are not limited.

For example, in some embodiments, the condensation dehumidifying part is a water-cooled condensation dehumidifying part, specifically, a condensation water channel is formed in the condensation dehumidifying part, the condensation dehumidifying part is connected to a water source, the water source exchanges heat with the damp-heat air flow in the process of flowing through the condensation water channel, the water absorbs heat of the damp-heat air flow, water vapor in the damp-heat air flow is separated from the air flow due to temperature reduction and is condensed into water drops, the water drops are mixed into the water, and finally the water drops are discharged, so that the effect of dehumidifying and temperature reduction on the damp-heat air flow is achieved. The heating element may be resistive heating.

In other embodiments, the laundry treatment apparatus comprises a heat pump system, i.e. the laundry treatment apparatus is a heat pump laundry treatment apparatus. The heat pump system includes at least a compressor, an evaporator, a condenser, and a throttle member, and a refrigerant medium circulates in the compressor, the evaporator, the condenser, and the throttle member. When the refrigerant flows through the evaporator, the outer surface of the evaporator is in a low-temperature environment, and when the refrigerant flows through the condenser, the outer surface of the condenser is in a high-temperature environment.

The condensing and dehumidifying part is an evaporator, the heating part is a condenser, and the condenser is arranged at the downstream of the evaporator along the airflow flowing direction. Illustratively, both the evaporator and the condenser are fin-type structures.
