[0038] An embodiment of the present application provides a clothing processing device, including a foam delivery module 100 and a foam channel.

[0039] Exemplarily, the laundry processing apparatus includes a laundry processing chamber 300a (refer to Figure 2), the clothing processing chamber 300a is used for placing clothing.

[0040] Exemplarily, the laundry processing device includes a drum assembly and a box 31 (refer to Figure 1 and Figure 7 ), the drum assembly has a laundry processing chamber 300a and is disposed in the box body 31. The front side of the laundry processing chamber 300a forms a laundry access opening. The user takes the laundry from the front side of the laundry processing device, see Figure 3 The clothing processing device includes a door body 32, and the door body 32 is used to open or close the clothing access opening.

[0041] For example, see Figure 2 and Figure 3 The drum assembly at least includes a clothing processing drum 300 , the space inside the clothing processing drum 300 is a clothing processing chamber 300 a , and the clothing processing drum 300 is rotatably disposed in the box body 31 .

[0042] For example, see Figure 1 and Figure 7 The box body 31 includes a front plate 311, a left support plate, a right support plate 312, a top cover plate 313 and a back plate. The front plate 311, the left support plate, the right support plate 312, the top cover plate 313 and the back plate are all appearance parts of the clothing processing device.

[0043] Exemplarily, the door body 32 is connected to the front plate 311 .

[0044] Please refer to Figure 4 , Figure 5 and Figure 6 The foam delivery module 100 has a receiving chamber 111c, and the receiving chamber 111c is used to contain a mixed liquid formed by mixing a cleaning medium and a dissolving medium. The foam delivery module 100 is used to generate foam from the mixed liquid.

[0045] The type of dissolving medium is not limited, and may be, for example, water, an organic solvent, or the like.

[0046] In the embodiments of the present application, water is used as the dissolving medium for description.

[0047] The foam delivery module 100 has a foam outlet 100 a , and the foam generated by the foam delivery module 100 is discharged from the foam delivery module 100 through the foam outlet 100 a .

[0048] It should be noted that in some embodiments, the mixed liquid can be directly injected into the containing chamber 111c, or the dissolving medium (for example, water) and the cleaning medium can be separately injected into the containing chamber 111c, and the dissolving medium and the cleaning medium are mixed in the containing chamber 111c to obtain the above-mentioned mixed liquid.

[0049] The foam channel connects the foam outlet 100a and the clothing processing chamber 300a, and is used to put foam into the clothing processing chamber 300a. Specifically, the inlet end of the foam channel is connected to the foam outlet 100a, and the outlet end of the foam channel extends into the clothing access opening, thereby putting foam into the clothing processing chamber 300a.

[0050] The foam channel refers to the entire path used to deliver the foam.

[0051] The clothes treatment device can use foam and clean the clothes in a non-immersion mode. The non-immersion mode refers to no liquid water immersion.

[0052] The clothes processing device uses foam to clean clothes in a non-immersion manner, which means that the foam enters the clothes processing chamber 300a and the clothes are cleaned by the cleaning medium carried by the foam. During this process, the clothes will not be soaked by water.

[0053] Since the clothes are cleaned in a non-immersion manner, there is no need to soak them with water. A large amount of foam can be injected into the clothes processing chamber 300a. For example, while the foam is injected into the clothes processing chamber 300a, the clothes processing drum 300 is rotated. This can promote full contact between the foam and the clothes, so that the clothes can have a large area of ​​contact with the foam, have better cleaning ability, improve the clothing processing efficiency, and can clean some clothes that cannot be washed by soaking in water. After the foam cleaning is completed, the water content of the clothes is not high. After the foam cleaning process is completed, the drying process is carried out, which can save drying time and improve drying efficiency. There is basically no need to drain water during the foam cleaning process. Therefore, it can be applied to clothes processing equipment that does not require washing water. Of course, it can also be applied to equipment such as washing machines, but the washing machine does not need to inject washing water for soaking clothes into the clothes processing chamber 300a during the foam cleaning process.

[0054] The specific type of the cleaning medium is not limited, for example, it can be a dry cleaning agent, laundry detergent, etc., which is not limited here.

[0055] The specific type of clothing processing equipment is not limited, for example, including but not limited to: washing machine, dryer, washer-dryer, etc.

[0056] Among them, a clothes dryer refers to a device that has the function of drying clothes but does not have the function of washing clothes by soaking them in water. A washer-dryer refers to a device that has the function of washing clothes by soaking them in water and also has the function of drying clothes.

[0057] It should be noted that the foam delivery module 100 is not limited to any method for foaming the mixed liquid.

[0058] For example, see Figure 3 and Figure 4The foam delivery module 100 includes a foam pump 112. The foam pump 112 extracts the mixed liquid in the accommodating chamber 111c and foams it into foam inside the foam pump 112. The foam is discharged from the foam outlet 100a. Figure 6 , Figure 6 The dashed line and arrows indicate the flow path of the mixed liquid pumped by the foam pump 112 .

[0059] The specific structure of the foam pump 112 is not limited, and any foam pump 112 in the prior art may be used.

[0060] Exemplarily, the foam delivery module 100 has an overflow channel, and the overflow channel is used to receive and guide the fluid overflowing from the accommodating chamber 111c.

[0061] The fluid guided out of the overflow channel can be drained away from the drain channel of the laundry treating apparatus.

[0062] Exemplarily, the foam delivery module 100 includes a shell assembly 111 , a portion of the internal space of the shell assembly 111 defines the aforementioned accommodating cavity 111 c , and another portion defines the aforementioned overflow channel.

[0063] In the embodiment of the present application, when the amount of the mixed liquid in the accommodating chamber 111c exceeds the upper limit value, the excess mixed liquid can be discharged from the overflow channel to prevent the mixed liquid in the accommodating chamber 111c from leaking and wetting other components, thereby improving the electrical safety of the clothing processing equipment.

[0064] For example, in some embodiments, the circumferential side wall of the laundry treatment drum 300 may be a continuous wall that the fluid medium cannot pass through, that is, the laundry treatment drum 300 is a non-porous inner drum. During the rotation of the laundry treatment drum 300, the foam in the laundry treatment drum 300 will not directly pass through the laundry treatment drum 300, thus preventing the foam from flowing to the outside of the laundry treatment drum 300, and effectively keeping the foam in the laundry treatment drum 300, thereby ensuring the cleaning effect of the foam on the clothes.

[0065] It can be understood that a hole-free inner drum means that the circumferential side wall of the clothing treatment drum 300 along the radial direction may not have any holes; or there may be a small number of holes, and, during the process of foam cleaning of clothes, these holes are in a closed state, for example, the valve is used to close the holes so that the foam does not pass through the holes and flow to the outside of the clothing treatment drum 300.

[0066] The clothing processing device as a whole may or may not be equipped with a drain pipe. For example, in some condensing clothes drying devices, the drain pipe is used to discharge the condensed water used to condense and cool the hot air flow. Heat pump clothes drying devices may be equipped with a drain pipe, which can be used to discharge the condensed water condensed from the humid hot air flow, etc., or the condensed water may be collected without a drain pipe. For another example, the washing machine itself is equipped with a drain pipe.

[0067] In some embodiments, the overflow channel can not only receive the fluid overflowing from the accommodating chamber 111 c , but also receive the fluid from other parts of the foam delivery module 100 .

[0068] For some examples, see Figure 7 The box body 31 is provided with a filling port 31b; the filling port 31b is connected to the accommodating chamber 111c, and the user can manually pour the cleaning medium, the dissolving medium or the mixed liquid into the accommodating chamber 111c from the filling port 31b.

[0069] For example, see Figure 3 The foam delivery module 100 includes a liquid pump 113, which is used to detachably dock with the container 200 to suck the cleaning medium, dissolving medium or mixed liquid stored in the container 200 and pump it to the accommodating chamber 111c. It should be noted that when the container 200 is used to hold the cleaning medium, the liquid pump 113 extracts the cleaning medium. When the container 200 is used to hold the mixed liquid, the liquid pump 113 extracts the mixed liquid. When the container 200 is used to hold the dissolving medium, the liquid pump 113 extracts the dissolving medium.

[0070] The liquid extraction pump 113 can quantitatively extract the cleaning medium, the dissolving medium or the mixed liquid in the container 200, so as to quantitatively control the flow rate and improve the consistency of the foam.

[0071] The specific structure of the liquid pump 113 is not limited, and any liquid pump 113 in the prior art can be used.

[0072] For example, see Figure 5 The foam delivery module 100 has a diversion channel 111f. For example, the structure of the housing assembly 111 itself forms the diversion channel 111f. One end of the diversion channel 111f is located below the docking port 113a of the liquid pump 113, and the other end is connected to the overflow channel, so as to divert the fluid leaking from the docking port 113a to the overflow channel.

[0073] The docking port 113a refers to the portion where the liquid pump 113 is docked with the container 200, and the portion where the liquid pump 113 is docked with the side wall of the accommodating chamber 111c. When the liquid pump 113 is extracting the cleaning medium, the dissolving medium or the mixed liquid, the docking port may leak, so the diversion channel 111f can divert the leaked cleaning medium, the dissolving medium or the mixed liquid to the overflow channel for centralized discharge through the overflow channel.

[0074] For example, see Figure 5 The foam dispensing module 100 has a drawer space 111a, and the clothing treatment device includes a drawer box for accommodating the container 200, and the container 200 is detachably placed in the drawer box. The drawer box is drawable and arranged in the drawer space 111a. The foam dispensing module 100 provides a receiving space and installation support for the drawer box, so that there is no need to set a mounting structure for the drawer box on the inner wall of the box body 31, thereby reducing the structural requirements for the box body 31.

[0075] It should be noted that, in this embodiment, please refer to Figure 1 The box body 31 has an opening 31 a , and the drawer box can be at least partially drawn out to the outside of the box body 31 through the opening 31 a .

[0076] When the container 200 needs to be replaced, the drawer box is pulled out, the container 200 in the drawer box is taken out, and the replaced container 200 is put into the drawer box. In this way, it is convenient for the user to take and put the container 200.

[0077] In some embodiments, the container 200 may be a disposable device. After the cleaning medium, dissolving medium or mixed liquid stored in the container 200 is used up, the old container 200 may be taken out and replaced with a new container 200.

[0078] In some other embodiments, the container 200 can be reused. After the cleaning medium, dissolving medium or mixed liquid in the container 200 is used up, the user can fill the container 200 with the cleaning medium, dissolving medium or mixed liquid, and the container 200 can be reused, which is energy-saving and environmentally friendly.

[0079] Exemplarily, the pull-out space 111a and the accommodating cavity 111c are isolated from each other, that is, there is no inclusive relationship between the two, the pull-out space 111a will not be arranged in the accommodating cavity 111c, and the accommodating cavity 111c will not be arranged in the pull-out space 111a.

[0080] Please continue reading Figure 5 The draw-out space 111a is located above the top wall of the accommodating cavity 111c. In this way, the space in the height direction can be fully utilized, making the foam delivery module 100 compact.

[0081] Exemplarily, the shape of the drawer space 111 a is roughly rectangular, and the drawer box is also roughly rectangular, which can accommodate a bottle-shaped container 200 .

[0082] For example, see Figure 4 and Figure 5 The foam delivery module 100 has an installation space 111g, and the liquid pump 113 is arranged in the installation space 111g. The installation space 111g is located at the rear side of the pull-out space 111a along the front-to-back direction of the clothing processing device. On the one hand, the rear side of the pull-out space 111a has enough space to install the liquid pump 113. On the other hand, the liquid pump 113 is located at the rear side of the pull-out space 111a, which is convenient for the liquid pump 113 and the container 200 to dock along the front-to-back direction. Specifically, when the pull-out box is pushed into the pull-out space 111a from the opening 31a, the container 200 in the pull-out box docks with the liquid pump 113. When the pull-out box is pulled out, the container 200 is separated from the liquid pump 113.

[0083] For example, see Figure 5 The foam delivery module 100 has a liquid collecting chamber 111d and a partition wall 1111. The partition wall 1111 is arranged between the liquid collecting chamber 111d and the accommodating chamber 111c, that is, the liquid collecting chamber 111d and the accommodating chamber 111c are located on opposite sides of the partition wall 1111. The side wall or the bottom wall of the liquid collecting chamber 111d is provided with an outlet 111d″, and the fluid collected in the liquid collecting chamber 111d is discharged from the outlet 111d″. The liquid collecting chamber 111d and the outlet 111d″ define the above-mentioned overflow channel.

[0084] The partition wall 1111 is provided with an overflow port 1111a, and the fluid in the receiving chamber 111c overflows to the liquid collecting chamber 111d through the overflow port 1111a. The height of the overflow port 1111a determines the theoretical maximum liquid level of the receiving chamber 111c. When the actual liquid level in the receiving chamber 111c reaches the height of the overflow port 1111a, if the receiving chamber 111c is still continuously filled with fluid (the fluid can be water, a cleaning medium, or a mixed liquid), the excess fluid overflows from the overflow port 1111a.

[0085] In this embodiment, the accommodating chamber 111c and the liquid collecting chamber 111d are arranged adjacent to each other, which can make the foam delivery module 100 compact in structure.

[0086] For example, see Figure 5 , the liquid pump 113 is disposed above the top wall of the liquid collecting chamber 111d. That is, the installation space 111g is located above the top wall of the liquid collecting chamber 111d. It should be noted that the liquid pump 113 is not disposed in the liquid collecting chamber 111d.

[0087] In this embodiment, the space above the liquid collecting chamber 111d can be fully utilized to install the liquid pump 113, so that the foam delivery module 100 has a compact structure.

[0088] Exemplarily, the liquid collecting chamber 111d is located at the rear side of the accommodating chamber 111c along the front-rear direction of the laundry processing device. In this embodiment, the liquid collecting chamber 111d is located at the rear side, making full use of the space at the rear side of the accommodating chamber 111c, and also facilitating the discharge of overflowing fluid from the rear.

[0089] For example, see Figure 4 and Figure 5 The clothing treatment device includes a water inlet valve 13, which is used to inject water into the accommodating chamber 111c. Specifically, the foam delivery module 100 has a water inlet 100b, and the water inlet valve 13 is connected to the water inlet 100b through a water inlet pipeline 14, and water and cleaning medium are mixed in the accommodating chamber 111c to generate a mixed liquid.

[0090] In this embodiment, since the cleaning medium and water are diluted and mixed in the foam delivery module 100 , the concentration of the cleaning medium in the container 200 can be relatively high, thus reducing the volume of the container 200 .

[0091] For example, see Figure 5 The water inlet valve 13 is disposed in the liquid collecting chamber 111d. Thus, when water leaks at the connection between the water inlet valve 13 and the water inlet pipeline 14, the leaked water can enter the liquid collecting chamber 111d and be discharged through the outlet 111d″ of the liquid collecting chamber 111d.

[0092] Exemplarily, the clothes processing apparatus includes a control unit and a liquid level monitoring unit, the liquid level monitoring unit is used to monitor the liquid level in the accommodating cavity 111c, and the control unit is used to control the water inlet valve 13 to open or close according to the monitoring signal of the liquid level detection unit.

[0093] It should be noted that the liquid level detection unit may send out a monitoring signal when the liquid level of the containing chamber 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 containing chamber 111c.

[0094] For example, during water injection, when the liquid level of the accommodating chamber 111c reaches the designed liquid level value, the liquid level monitoring unit sends a monitoring signal, and the control unit controls the water inlet valve 13 to close to stop injecting water into the accommodating chamber 111c. If the liquid level of the accommodating chamber 111c does not reach the designed liquid level value, the liquid level monitoring unit may not send a monitoring signal, and the control unit may control the water inlet valve 13 to continue to inject water. Of course, when the water injection amount of the water inlet valve 13 reaches the required flow rate at that time, even if the liquid level does not reach the designed liquid level value, the control unit may control the water inlet valve 13 to close to stop injecting water into the accommodating chamber 111c.

[0095] Even if the water inlet valve 13 continues to inject water into the accommodating chamber 111 c due to a malfunction, excess liquid in the accommodating chamber 111 c can overflow into the overflow channel and then be discharged from the overflow channel, thereby improving safety.

[0096] The specific structural form of the liquid level monitoring unit is not limited, and any technology that can realize liquid level monitoring in the prior art can be used.

[0097] Exemplarily, the liquid level detection unit includes a float 17 (see Figure 5 ) and a sensor, a float 17 is disposed in the accommodating chamber 111c, and the float 17 is used to trigger the sensor to generate a monitoring signal when floating to a preset height. The sensor and the control unit perform information exchange, which can be wireless communication exchange or wired communication exchange.

[0098] The float 17 floats on the liquid surface and moves up and down as the height of the liquid level changes. When the liquid level reaches the designed liquid level value, the height of the float 17 can just trigger the sensor to generate a monitoring signal.

[0099] It should be noted that the control unit can be a relatively independent circuit board component arranged in the foam delivery module 100, or it can be the main control board of the entire clothing processing device, and there is no limitation here.

[0100] The source of water in the water inlet valve 13 is not limited. For example, it can be connected to an external tap water pipe, or it can be connected to a condensed water box of a clothing processing device, wherein the water in the condensed water box comes from the condensed water collected after the clothing processing device condenses the hot and humid air flow during the drying process of clothes; it can also be connected to water added by the user, etc., which is not limited here.

[0101] Of course, in other embodiments, the user can manually add the required water to the foam delivery module 100 , that is, the water does not need to be introduced through the water inlet valve 13 , but the user can manually add water.

[0102] Exemplarily, the foam delivery module 100 is a preassembled unit, and on a production line of the clothing processing equipment, the preassembled unit is assembled in the box body 31, thus improving the assembly efficiency.

[0103] Exemplarily, the laundry treating apparatus comprises an electrical structure, wherein the electrical structure comprises at least one of a motor, a compressor, and a circuit board.

[0104] In a plane projection perpendicular to the height direction of the clothing processing apparatus, the foam delivery module 100 and the electrical structure are arranged on opposite sides of the barrel assembly. For example, the foam delivery module 100 is located on the left side of the barrel assembly, and the electrical structure is located on the right side of the barrel assembly; or, the foam delivery module 100 is located on the right side of the barrel assembly, and the electrical structure is located on the left side of the barrel assembly.

[0105] In this embodiment, since the foam delivery module 100 and the electrical structure are arranged on opposite sides of the barrel assembly, even if the foam delivery module 100 or the water inlet assembly leaks, it will not drip onto the electrical structure, thereby improving the waterproof safety of the clothing treatment equipment. It should be noted that the above-mentioned motor is used to directly or indirectly drive the above-mentioned clothing treatment barrel 300 to rotate. The compressor is a compressor of the heat pump system, which is used to compress the refrigerant. The circuit board can be a main control board of the whole machine, or a frequency conversion control board for controlling the compressor, or other types of circuit boards.

[0106] It should be noted that the foam delivery module 100 and the electrical structure are arranged on opposite sides of the barrel assembly, including multiple situations: the foam delivery module 100 and the motor are located on opposite sides of the barrel assembly; and / or, the foam delivery module 100 and the compressor are located on opposite sides of the barrel assembly; and / or, the foam delivery module 100 and the circuit board are located on opposite sides of the barrel assembly. In other words, even if the electrical structure includes multiple components, it is not necessary to require that the foam delivery module 100 and all components of the electrical structure are located on opposite sides of the barrel assembly. For example, when the electrical structure includes a compressor and a motor, in one embodiment: the motor and the foam delivery module 100 are located on opposite sides of the barrel assembly, and the compressor and the foam delivery module 100 are located on the same side of the barrel assembly; in another embodiment: the motor and the compressor are located on the same side of the barrel assembly, and both and the foam delivery module 100 are located on opposite sides of the barrel assembly.

[0107] For example, taking a clothes dryer as an example, see Figure 1 and Figure 2 The laundry processing apparatus includes a front support 500 , which is disposed at the front side of the laundry processing tub 300 .

[0108] For example, see Figure 2 , the front support 500 has a through opening 500b, and the through opening 500b runs through the front support 500. The inlet end of the foam channel is connected to the foam outlet 100a, and the outlet end of the foam channel passes through the through opening 500b and extends into the clothing access opening to put the foam into the clothing processing chamber 300a. In this embodiment, the front support 500 is used to provide an installation position for the foam channel, which is convenient for introducing the foam into the clothing processing chamber 300a. Specifically, since the clothing processing drum 300 needs to rotate and the front support 500 does not rotate, the foam channel passes through the through opening 500b of the front support 500, which can not only guide the foam to the clothing processing chamber 300a, but also avoid interference with the clothing processing drum 300.

[0109] For example, taking a washing machine as an example, the clothing processing device includes a front sealing door and a door sealing ring, and the door sealing ring is arranged on the front sealing door, and is used to seal the space between the clothing access opening and the door body 32, so that when the door body 32 is closed, the clothing processing chamber 300a becomes a relatively sealed space without water leakage. In this embodiment, a through hole 500b is arranged on the front sealing door and / or the door sealing ring, and the outlet end of the foam channel passes through the through hole 500b.

[0110] Exemplarily, the through-opening 500 b substantially penetrates the front support 500 along the front-to-back direction.

[0111] For example, see Figure 2 The clothes treating device includes a pipe 15, one end of which is connected to the foam outlet 100a, the space in the pipe 15 defines at least a part of the foam channel, and one end of the pipe 15 away from the foam outlet 100a extends to the front side of the clothes taking-in and putting-out opening, or extends into the clothes taking-in and putting-out opening. The foam is guided by the pipe 15, which is convenient for bending according to the required foam path, thereby improving the layout flexibility.

[0112] Exemplarily, the pipeline 15 is located at the front side of the front support 500, that is, the pipeline 15 and the barrel assembly are located at opposite sides of the front support 500 in the front-to-back direction. Specifically, the pipeline 15 is located in the spacing area between the front support 500 and the front plate 311. The pipeline 15 and the foam outlet 100a are both located at the front side of the front support 500, and the pipeline 15 hardly affects the arrangement of the barrel assembly, and can also make full use of the spacing area at the front side of the front support 500.

[0113] The pipeline 15 may be an integrated pipeline, or may be formed by connecting multiple pipeline sections, which is not limited here.

[0114] In some embodiments, the end of the pipe 15 serves as an outlet of the foam channel. That is, in this embodiment, the pipe 15 independently defines a foam channel.

[0115] Illustratively, in the laundry processing apparatus with the front support 500, the second end of the pipeline 15 passes through the through opening 500b and extends into the laundry taking-in and putting-out opening, and the foam is discharged from the end of the pipeline 15 and delivered to the laundry processing chamber 300a.

[0116] In some other embodiments, please refer to Figure 2 The clothing treatment device includes a nozzle 16, and a pipe 15 connects the foam outlet 100a and the nozzle 16, that is, the nozzle 16 is connected to one end of the pipe 15 away from the foam outlet 100a, and the space in the pipe 15 and the space in the nozzle 16 jointly define a foam channel.

[0117] In this embodiment, foam is delivered into the clothing processing chamber 300a through the nozzle 16. The foam has an initial velocity, which not only facilitates the full dispersion of the foam, allowing the foam to have a larger contact area with the clothing in the clothing processing chamber 300a, but also accelerates the discharge of the foam generated by the foam delivery module 100, thereby improving efficiency.

[0118] For example, in the clothes treating apparatus having the front support 500, the spray head 16 passes through the through opening 500b and extends into the clothes taking-in and putting-out opening.

[0119] Exemplarily, the position of the foam outlet 100a is not lower than the position of the through opening 500b. In this embodiment, the resistance of conveying foam from the foam outlet 100a to the end of the foam channel is smaller, thereby improving the smoothness of foam conveying.

[0120] For example, see Figure 2 The front support 500 has a communication port 500a, which is communicated with the clothing taking-in and putting-out port, and the communication port 500a surrounds the clothing taking-in and putting-out port. In the process of taking-in and putting-out clothing, clothing will pass through the communication port 500a.

[0121] It should be noted that the communication opening 500a is smaller than the clothing taking-in and putting-out opening.

[0122] The location of the through opening 500b is not limited as long as it is convenient for the foam channel to pass through.

[0123] For example, the through-port 500b is provided on the left side, the right side, the upper left side, the upper right side, or directly above the communication port 500a.

[0124] See also Figure 2 For example, the through-port 500b is arranged in the upper area of ​​the connecting port 500a. On the one hand, the position of the outlet end of the foam channel is relatively high, and the foam is dropped into the clothing processing chamber 300a from above. In this way, the foam can fall in a parabola under the action of its initial velocity and gravity, making the foam more dispersed, and enabling the foam to cover a larger area in the clothing processing chamber 300a, so as to facilitate full contact between the foam and the clothes, thereby improving the cleaning effect. On the other hand, it can also reduce the probability of the clothes blocking the outlet of the foam channel.

[0125] It should be noted that the upper region of the communication opening 500a refers to a region located higher than the communication hole.

[0126] Exemplarily, the foam delivery module 100 is connected to at least one of the housing 31, the front support 500, or the front sealing door. In this embodiment, the foam delivery module 100 does not need to be installed through the barrel assembly. Exemplarily, the front support 500 may be a structure belonging to a clothes dryer, and the front sealing door may be a structure belonging to a washing machine. That is, for a clothes dryer, the foam delivery module 100 may be connected to the housing 31 and / or the front support 500. For a washing machine, the foam delivery module 100 may be connected to the housing 31 and / or the front sealing door.

[0127] For example, see Figure 3 In a plane perpendicular to the height direction of the laundry processing apparatus, the foam delivery module 100 is located on a first side of the axis L1 of the barrel assembly, and the foam outlet 100a is located on a side wall of the foam delivery module 100 facing the axis L1.

[0128] For example, in some embodiments, see Figure 3 In a plane perpendicular to the height direction of the clothes processing device, the entire foam delivery module 100 is located on 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, in a plane perpendicular to the height direction of the clothes processing device, the entire foam delivery module 100 is located on the right side of the axis, and the foam outlet 100a is provided on the left side wall of the foam delivery module 100.

[0129] In this embodiment, the location of the foam outlet 100a facilitates the connection between the foam outlet 100a and the foam channel, and can also be closer to the clothing access opening, further shortening the length of the foam channel.

[0130] In the embodiment of the present application, the axis L1 of the drum assembly refers to the rotation axis of the laundry processing drum 300 .

[0131] Exemplarily, the position of the foam dispensing module 100 is not lower than the center of the clothing access opening, that is, not lower than the axis of the barrel assembly. Any part of the foam dispensing module 100 is not lower than the axis of the barrel assembly. For example, the foam dispensing module 100 is arranged at the upper left or upper right of the clothing treatment barrel 300.

[0132] In the embodiment of the present application, the center of the clothing access opening is located on the axis L1 of the drum assembly.

[0133] The location height of the foam delivery module 100 makes it easy for the user to add cleaning medium to the foam delivery module 100 without bending over. In addition, there is also a large space to install the foam delivery module 100.

[0134] For example, in some embodiments, the laundry processing device is a single-drum structure, that is, there is only one drum, namely, the laundry processing drum 300, and there is no outer barrel outside the laundry processing drum 300. In other embodiments, an outer barrel is further provided outside the laundry processing drum 300.

[0135] In some embodiments, the barrel assembly is a single barrel structure, see Figure 6 , the foam delivery module 100 has a curved outer surface 111b, and the curved outer surface 111b is used to avoid the outer surface of the barrel assembly and the two are arranged at an interval. That is, the two do not contact. When the barrel assembly moves or rotates, the two will not interfere with each other. In addition, the vibration of the barrel assembly will not directly act on the foam delivery module 100, reducing the impact of the vibration on the foam delivery module 100. In addition, the adaptation of the curved outer surface 111b and the outer surface of the barrel assembly is utilized to make the foam delivery module 100 fit the barrel assembly setting as closely as possible, without interference, and fully utilizing the installation space 111g; in addition, in the clothing processing device with a front support 500, the curved outer surface 111b also facilitates the connection between the foam delivery module 100 and the front support 500.

[0136] Exemplarily, the position of the foam outlet 100a is not lower than the top edge of the clothing access opening. In other words, the position of the foam outlet 100a is relatively high, which facilitates the foam to flow from the foam outlet 100a to the clothing access opening through the foam channel.

[0137] Exemplarily, the position of the outlet of the foam channel is not lower than the center of the clothing access opening. In this way, the foam is put into the clothing processing chamber 300a from a relatively high position, so that the foam can fall in a parabola under the action of its initial velocity and gravity, making the foam more dispersed, and the foam can cover a larger area in the clothing processing chamber 300a, which is convenient for the foam and the clothing to fully contact, thereby improving the cleaning effect, and on the other hand, it can also reduce the probability of clothing blocking the outlet of the foam channel.

[0138] Exemplarily, the clothing treatment device includes an air duct, which is in communication with the clothing treatment chamber 300a and is used to provide airflow to the clothing treatment chamber 300a. It is understandable that the air duct has a heating element inside, and the heating element is used to heat the airflow. When the heating element is heated, the air duct provides a hot airflow into the clothing treatment chamber 300a to dry the clothing by the hot airflow. For example, after the clothing is cleaned with foam, the hot airflow is used to dry the clothing and take away the solvent and moisture in the foam, thereby removing the foam and drying the clothing.

[0139] Exemplarily, the clothing treatment device includes a condensation dehumidification component, which is used to condense and dehumidify the airflow discharged from the clothing treatment chamber 300a. Specifically, the dry hot airflow of the air duct flows to the clothing treatment chamber 300a. In the process of flowing through the clothing treatment chamber 300a, the dry hot airflow exchanges heat with the clothing and takes away a part of the water vapor to form a humid hot airflow. The humid hot airflow is discharged from the clothing treatment chamber 300a and contacts the condensation dehumidification component. Since the water vapor in the humid hot airflow is precipitated due to the cooling, the airflow after condensation and dehumidification by the condensation dehumidification component becomes a low-temperature dry airflow.

[0140] In some embodiments, the airflow discharged from the clothing processing chamber 300a flows to the external environment, that is, the discharged airflow does not circulate into the clothing processing chamber 300a. It is understandable that in an embodiment where a condensation and dehumidification component is not provided, the airflow discharged from the clothing processing chamber 300a flows directly to the external environment without condensation and dehumidification by the condensation and dehumidification component, that is, the airflow flowing to the external environment is a humid and hot airflow, which will affect the temperature and humidity of the external environment. In an embodiment where a condensation and dehumidification component is provided, the airflow discharged from the clothing processing chamber 300a is condensed and dehumidified by the condensation and dehumidification component, so that the airflow flowing to the external environment is a low-temperature dry airflow, which can reduce the impact on the humidity and temperature of the external environment, and can also reduce the pollution of the external environment by fluff and other debris wrapped in the airflow.

[0141] In other embodiments, both ends of the air duct are respectively connected to the clothing processing chamber 300a to form a circulating airflow channel. The airflow can circulate in the clothing processing chamber 300a and the air duct. On the one hand, it can make full use of the heat energy, and on the other hand, it can also avoid the airflow being directly discharged to the external environment and causing adverse effects on the environment.

[0142] It should be noted that a heating element and a condensing and dehumidifying element are provided in the air duct, and the heating element is provided downstream of the condensing and dehumidifying element along the air flow direction, that is, the hot and humid air flow flowing out of the clothing processing chamber 300a first flows through the condensing and dehumidifying element, and then flows through the heating element. The condensing and dehumidifying element is used to condense and dehumidify the air flow, and the heating element is used to heat the air flow.

[0143] The working process and drying principle of the clothing processing device of the embodiment of the present application are as follows: a dry hot air flow enters the clothing processing chamber 300a from the downstream of the air duct along the air flow direction; in the clothing processing chamber 300a, the dry hot air flow flows through the surface of the wet clothes, exchanges heat and moisture with the wet clothes, absorbs moisture in the clothes, and becomes a humid hot air flow; the humid hot air flow enters the upstream of the air duct, and flows through the condensation and dehumidification component and the heating component in sequence; in the process of flowing through the condensation and dehumidification component, the water vapor in the humid hot air flow is precipitated from the air flow due to cooling and condenses into water droplets; the humid hot air flow is condensed and dehumidified by the condensation and dehumidification component to form a low-temperature dry air flow; the low-temperature dry air flow is heated into a dry warm air flow when passing through the heating component; the dry hot air flow enters the clothing processing chamber 300a from the downstream of the air duct again; and the cycle is repeated to achieve continuous drying of the clothes.

[0144] It should be noted that the low-temperature dry airflow is relative to the humid hot airflow, and the temperature of the low-temperature dry airflow is lower than that of the humid hot airflow. The low temperature in the embodiment of the present application may be room temperature.

[0145] The specific types of the above-mentioned condensing and dehumidifying components and heating components are not limited.

[0146] For example, in some embodiments, the condensation dehumidification element is a water-cooled condensation dehumidification element. Specifically, the condensation dehumidification element has a condensation water channel inside, and the condensation dehumidification element is connected to a water source. When the water source flows through the condensation water channel, the water exchanges heat and mass with the humid hot air flow, and the water absorbs the heat of the humid hot air flow. The water vapor in the humid hot air flow is separated from the air flow due to the cooling and condenses into water droplets. The water droplets are mixed with water and finally discharged, thus achieving the effect of dehumidifying and cooling the humid hot air flow. The heating element can be a resistance heater.

[0147] In some other embodiments, the clothing processing device includes a heat pump system, that is, the clothing processing device is a heat pump type clothing processing device. The heat pump system includes at least a compressor, an evaporator, a condenser and a throttling device, and the refrigerant medium circulates in the compressor, the evaporator, the condenser and the throttling device. When the refrigerant flows through the evaporator, the outer surface of the evaporator is a low-temperature environment, and when the refrigerant flows through the condenser, the outer surface of the condenser is a high-temperature environment.

[0148] The condensing and dehumidifying element is an evaporator, the heating element is a condenser, and the condenser is arranged downstream of the evaporator along the airflow direction. Exemplarily, both the evaporator and the condenser are fin-type structures.

[0149] For example, see Figure 2 The clothes processing device includes a base 400, the clothes processing drum 300 is arranged above the base 400, and the heat pump system is arranged on the base 400. That is, the base 400 provides installation support for the heat pump system.

[0150] For heat pump dryers, see Figure 3The clothing processing device includes a rear cover, the space inside the rear cover is located on the air flow path of the air duct, and the air flow coming out of the air duct on the base 400 is guided through the rear cover to the end cover of the axial rear end of the clothing processing drum 300, and enters the clothing processing chamber 300a from the end cover.

[0151] For example, see Figure 2 The bottom wall of the communication opening 500a of the front support 500 is provided with an air duct inlet 500c, and the air flow in the clothing processing chamber 300a enters the air duct through the air duct inlet 500c.

[0152] Exemplarily, a filter may be provided at the air duct inlet 500c, and the filter is used to filter debris such as fluff entrained in the airflow.
