Description

Technical Field

[0001] This application relates to the field of clothing processing technology, and in particular to an isolation air duct assembly for a multi-tube clothing processing device and a multi-tube clothing processing device. Background Technology

[0002] With the development of market demand, in multi-drum garment processing devices with multiple garment processing tanks, all or most of the garment processing tanks need to be designed as integrated washer-dryer water tanks. Due to cost and space limitations, multi-drum garment processing devices often only have one drying unit, which is then connected to multiple water tanks. In existing technologies, a common approach is to connect the drying unit to multiple water tanks via an air duct selection structure. This means that, based on the user's actual selection, the garment processing device controls the air duct selection structure to individually connect the corresponding water tank to the drying unit.

[0003] The above-mentioned technical solution of connecting the clothes handling tub and the drying device through the air duct selection structure cannot achieve the simultaneous connection of two clothes handling tubs and the drying device, that is, it cannot enable the two clothes handling tubs to perform drying operations at the same time, which cannot well meet the user's needs. There is an urgent need for a technical solution that can enable the two clothes handling tubs to perform drying operations at the same time. Utility Model Content

[0004] This application is made in view of the aforementioned state of the prior art. The purpose of this application is to provide an isolation air duct assembly for a multi-drum garment processing device, which enables the simultaneous and uniform introduction of drying airflow into two garment processing drums via a drying device and two air supply ducts.

[0005] This application also provides a multi-drum garment processing device including the above-mentioned isolation air duct, which can realize the simultaneous drying operation of two garment processing drums.

[0006] This application provides an isolation air duct assembly for a multi-drum garment processing device, used to introduce drying airflow into multiple garment processing drums. The isolation air duct comprises a first air inlet, a second air inlet, a first air duct, a second air duct, a first air outlet, a second air outlet, and an isolation section.

[0007] The first air inlet and the first air outlet are connected to the first air duct.

[0008] The second air inlet and the second air outlet are connected to the second air duct.

[0009] The isolation section separates the first air duct from the second air duct, making the first air duct and the second air duct independent of each other.

[0010] The multi-drum garment processing device provided in this application uses an isolation duct assembly to simultaneously and evenly supply drying airflow into two garment processing drums via two air supply ducts using a single drying device. This allows at least two garment processing drums of the multi-drum garment processing device to perform drying operations simultaneously. Furthermore, the two air supply ducts are separated by an isolation section, which can prevent mutual interference between the two air supply ducts and avoid cross-contamination such as water or foam overflow.

[0011] In at least one possible implementation, the pressure drop of the first air duct is greater than the pressure drop of the second air duct, and the area of ​​the first air inlet is greater than the area of ​​the second air inlet.

[0012] When the pressure drop of the first air duct and the second air duct is not equal, the area of ​​the two air inlets can be changed accordingly based on the pressure drop difference, so that the flow rate entering the different air supply ducts is different. Ultimately, under the effect of the air duct pressure drop, the drying airflow entering the two clothes processing drums is consistent or close.

[0013] In at least one possible implementation, the minimum cross-sectional area of ​​the first air duct is not less than the area of ​​the first air inlet, and the minimum cross-sectional area of ​​the first air duct is not less than the area of ​​the first air outlet.

[0014] The minimum cross-sectional area of ​​the second air duct is not less than the area of ​​the second air inlet, and the minimum cross-sectional area of ​​the second air duct is not less than the area of ​​the second air outlet.

[0015] The above-mentioned restrictions on the minimum cross-sectional area of ​​the air duct can avoid or reduce unnecessary airflow pressure loss caused by the air duct's small cross-sectional area after the drying airflow enters the air duct.

[0016] In at least one possible implementation, the first air inlet is provided with a first backflow preventer and the second air inlet is provided with a second backflow preventer to prevent water and foam from overflowing the isolation duct.

[0017] A backflow preventer structure is installed at the air inlet to effectively prevent water and foam from overflowing from the clothes handling drum into the isolation air duct, and in particular, to prevent water and foam from overflowing into the drying unit.

[0018] In at least one possible implementation, the isolation duct assembly for the multi-tube garment handling device further forms a first anti-reverse structure mounting groove and a second anti-reverse structure mounting groove for respectively mounting the first anti-reverse structure and the second anti-reverse structure.

[0019] Creating a dedicated mounting groove for the backflow preventer in the isolation duct makes it easier to install the backflow preventer and also makes the installation of the backflow preventer more secure.

[0020] In at least one possible implementation, the first air inlet and the second air inlet are adjacent to each other.

[0021] The first and second air inlets are positioned adjacent to each other to facilitate the connection of the isolation duct and the drying device through a single integrated pipeline.

[0022] In at least one possible implementation, the isolation duct assembly for the multi-tube garment handling device further includes an extended air inlet, an extended air duct, and an extended air outlet.

[0023] The extended air inlet and the extended air outlet are connected to the extended air duct.

[0024] The extended air duct is independent of the first air duct and the second air duct.

[0025] The isolated air duct can also be further expanded to accommodate multi-tube garment handling units that include more garment handling tubs.

[0026] In at least one possible implementation, the isolation duct assembly for the multi-tube garment handling device further includes a drying air inlet, wherein the pressure drop of the first duct is greater than the pressure drop of the second duct.

[0027] The drying air interface has an air inlet, a flow divider, and an air outlet, with the flow divider extending from the air inlet to the air outlet.

[0028] The cross-sectional area of ​​the air inlet of the interface is less than or equal to the cross-sectional area of ​​the air outlet of the interface.

[0029] The diverter plate divides the interface air inlet into a first interface air inlet and a second interface air inlet; the diverter plate divides the interface air outlet into a first interface air outlet and a second interface air outlet, the first interface air outlet being connected to the first air duct, and the second interface air outlet being connected to the second air duct.

[0030] The cross-sectional area of ​​the first air inlet of the interface is larger than the cross-sectional area of ​​the second air inlet of the interface.

[0031] The drying air interface can be specifically adjusted in cross-sectional area based on the pressure drop difference between the downstream first and second air ducts. Ordinary uniform interface cannot overcome the difference in drying airflow caused by the pressure drop difference in the air ducts, while this drying air interface can adjust the drying airflow in different air ducts to achieve uniform drying airflow into both clothes processing drums at the same time. This allows at least two clothes processing drums of a multi-drum clothes processing device to perform drying operations simultaneously with good consistency in the distribution of drying airflow.

[0032] In at least one possible implementation, the cross-sectional area of ​​the first air inlet of the interface is smaller than the minimum cross-sectional area of ​​the first air duct; the cross-sectional area of ​​the second air inlet of the interface is smaller than the minimum cross-sectional area of ​​the second air duct.

[0033] Making the cross-sectional area of ​​the air inlet of the interface smaller than the minimum cross-sectional area of ​​the air duct can prevent the flow rate and velocity of the drying air from being affected by the reduced cross-sectional area when passing through the air duct after entering the drying air interface, thus avoiding unnecessary pressure drop.

[0034] In at least one possible implementation, the cross-sectional area of ​​the first air inlet of the interface is less than or equal to the cross-sectional area of ​​the first air outlet of the interface.

[0035] The cross-sectional area of ​​the second air inlet of the interface is less than or equal to the cross-sectional area of ​​the second air outlet of the interface.

[0036] Making the cross-sectional area of ​​the air inlet of the interface less than or equal to the cross-sectional area of ​​the air outlet of the interface can reduce or avoid the pressure drop of the drying airflow in the drying air interface.

[0037] In at least one possible implementation, the end of the flow divider plate near the air inlet of the interface forms a first flow divider surface and a second flow divider surface.

[0038] Both the first and second diversion surfaces form an angle with the axial direction of the drying air interface.

[0039] The first diversion surface is close to the first air inlet of the interface, and the second diversion surface is close to the second air inlet of the interface.

[0040] The two splitting surfaces formed at the ends of the splitting plate can guide and split the drying airflow, allowing the drying airflow to enter the first and second air ducts more smoothly according to the preset flow differences.

[0041] In at least one possible implementation, the slope of the first splitting surface is less than the slope of the second splitting surface;

[0042] The guide length of the first diversion surface is greater than the guide length of the second diversion surface.

[0043] The parameters provided above enable the drying airflow entering the first air duct to be greater than the drying airflow entering the second air duct, in order to accommodate the larger pressure drop in the first air duct.

[0044] In at least one possible implementation, the drying air interface further includes a fixing part disposed on the outer periphery of the interface air outlet.

[0045] A fixing part is provided on the outer periphery of the air outlet to facilitate the connection of the drying air interface with other structures, especially with the air duct structure.

[0046] In at least one possible implementation, the drying air interface further includes a sealing ring groove formed on the outer periphery of the interface outlet for accommodating a sealing ring.

[0047] Adding a sealing ring to the air outlet of the drying air interface can improve the sealing between the drying air interface and its connected structure, preventing or reducing the leakage of drying air.

[0048] In at least one possible implementation, the upper surface of the diverter plate is parallel to or forms an angle with the lower surface of the diverter plate;

[0049] The upper and lower surfaces of the diverter plate are flat or curved plates.

[0050] The above content provides a preferred shape and structure for the flow divider, which can be adjusted as needed to achieve a more ideal flow guiding and diversion effect at the drying air interface.

[0051] This application also provides a multi-tub garment processing apparatus, which includes a first tub, a second tub, and a drying device; and an isolation air duct assembly for the aforementioned multi-tub garment processing apparatus.

[0052] The first barrel is connected to the first air outlet, the second barrel is connected to the second air outlet, and the drying device is directly or indirectly connected to the first air inlet and the second air inlet, so that the drying hot airflow generated in the drying device can enter the first barrel and the second barrel respectively through the isolation air duct.

[0053] The multi-drum clothing handling device provided in this application enables the simultaneous and uniform introduction of drying airflow into two clothing handling drums using a single drying unit via two air ducts. This allows at least two clothing handling drums of the multi-drum clothing handling device to perform drying operations simultaneously. Furthermore, the two air ducts are separated by an insulating section, preventing mutual interference and spillage of water or foam between them. Using only one drying unit to simultaneously dry multiple clothing handling drums saves energy, reduces clothing handling time, and improves the user experience. In at least one possible embodiment, the first and second drums are arranged side-by-side with the same opening direction.

[0054] The first air outlet is connected to the upper side of the peripheral wall of the first barrel opening, and the second air outlet is connected to the upper side of the peripheral wall of the second barrel opening, so that the drying hot airflow enters the barrel from the upper side of the opening of the first barrel and the upper side of the opening of the second barrel respectively.

[0055] By having the drying airflow enter the clothes processing drum from the upper side of the drum opening, the drying airflow can contact or flow through as many clothes as possible, thereby improving the drying effect of the clothes processing drum.

[0056] In at least one possible implementation, the multi-tub laundry handling device further includes an air outlet pipe connected to the bottom of the first tub and the bottom of the second tub, and the air outlet pipe is also connected to the drying device to form a drying airflow circulation.

[0057] The air outlet pipe is at least partially located above the first and second barrels, and the isolation air duct is at least partially located above the first and second barrels.

[0058] This design allows the drying airflow to enter from the opening of the drum and exit from the bottom. This design maximizes the amount of drying airflow passing through all or most of the clothes to be dried, thus making full use of the drying airflow and improving the drying effect.

[0059] In at least one possible embodiment, the multi-tube garment handling device further includes an air outlet conduit, which includes a first air outlet branch, a second air outlet branch, and a main air outlet conduit.

[0060] The first bucket and the second bucket are arranged side by side in a horizontal direction.

[0061] The first air outlet branch connects the first tank and the main air outlet path.

[0062] The second air outlet branch connects the second tank and the main air outlet path.

[0063] The main air outlet and the isolation air duct are staggered in the front-rear direction of the multi-tube clothing processing device.

[0064] The main air outlet duct and the front part of the air supply duct are staggered in the front-back direction of the multi-tube clothing processing device. This can improve the internal space utilization of the multi-tube clothing processing device, reduce the total space occupied by the air duct structure, and facilitate the miniaturization design of the multi-tube clothing processing device.

[0065] In at least one possible implementation, the main air outlet path has a filter receiving cavity, and the filter receiving cavity is provided with a filter for filtering the airflow entering the main air outlet path.

[0066] The filter housing cavity and the isolation air duct are offset in the front-back direction of the multi-tube clothing processing device.

[0067] Setting up a filter housing cavity and filter in the main air outlet duct allows for the use of a single filtration structure to filter the air from at least two garment processing drums. At the same time, setting the space-consuming filter housing cavity to be offset from the front of the air supply duct in the front-back direction of the multi-drum garment processing device can minimize the total space occupied by the duct structure.

[0068] The multi-drum garment handling device and the isolation duct assembly provided in this application enable the simultaneous and uniform introduction of drying airflow into two garment handling drums via two air supply ducts using a single drying unit. This allows at least two garment handling drums of the multi-drum garment handling device to perform drying operations simultaneously. Using a single drying unit to dry multiple garment handling drums simultaneously saves energy, reduces garment handling time, and improves the user experience. Attached Figure Description

[0114] Exemplary embodiments of this application are described below with reference to the accompanying drawings. It should be understood that these specific descriptions are for teaching those skilled in the art how to implement this application only, and are not intended to exhaustively describe all possible methods of this application, nor to limit the scope of this application.

[0115] This application provides an isolation duct assembly (hereinafter sometimes simply referred to as "isolation duct assembly") for a multi-tube garment handling device, such as... Figure 1 As shown, the isolation air duct assembly mainly includes an isolation air duct 400, which can be installed in a multi-drum clothes handling device with a clothes drying function. For example, as... Figure 1 As shown, the multi-tub garment handling device to which the isolation duct 400 is applicable may include a first tub 100, a second tub 200, and a drying device 300. It can be understood that the first tub 100 and the second tub 200 here can be garment handling tubs with garment drying functions, and in particular, they can be water tanks that are washer-dryer combos (with functions such as washing and drying).

[0116] The drying device 300 can heat air to form a hot airflow capable of drying clothes. The first drum 100 and the second drum 200 can be connected to the drying device 300 via an insulating air duct 400 to allow hot air to circulate into the first drum 100 and the second drum 200. The insulating air duct 400 can be directly or indirectly connected to the drying device 300, for example, as shown in... Figure 1 As shown, the isolation duct 400 can be indirectly connected to the drying device 300 (the air outlet volute of the drying device 300) through a pipe.

[0117] The interior of the isolation duct 400 can form two independent duct structures. Specifically, such as... Figure 2 , Figure 3 and Figure 4As shown, the isolation duct 400 can form a first air inlet 411, a second air inlet 412, a first air duct 421, a second air duct 422, a first air outlet 431, a second air outlet 432, and an isolation section 440. The first air inlet 411 and the first air outlet 431 are both connected to the first air duct 421, and the second air inlet 412 and the second air outlet 432 are both connected to the second air duct 422. Both the first air inlet 411 and the second air inlet 412 can be connected to the drying device 300 to introduce drying hot airflow into the duct. An isolation section 440 can be provided between the first air duct 421 and the second air duct 422 to separate them. The first air outlet 431 can be connected to the first barrel 100, and the second air outlet 432 can be connected to the second barrel 200 to introduce drying airflow into the first barrel 100 and the second barrel 200, respectively.

[0118] It is understandable that separating the first air duct 421 and the second air duct 422 can prevent the gas flow within them from affecting each other, and can also prevent water or foam from flowing into the other through the isolation air duct 400 when one of the first barrel 100 or the second barrel 200 overflows or spills foam.

[0119] like Figure 3 and Figure 4 As shown, the first air duct 421 has a longer and more tortuous path than the second air duct 422. The drying airflow is more likely to form a pressure loss in the first air duct 421, that is, the pressure drop of the first air duct 421 can be greater than that of the second air duct 422.

[0120] Preferably, based on the pressure drop difference between the first air duct 421 and the second air duct 422, the areas (i.e., cross-sectional areas or ventilation cross-sectional areas) of the first air inlet 411 and the second air inlet 412 can also have a corresponding difference. That is, when the pressure drop of the first air duct 421 is greater than the pressure drop of the second air duct 422, the area of ​​the first air inlet 411 can be greater than the area of ​​the second air inlet 422.

[0121] When the dimensions of the first barrel 100 and the second barrel 200 are the same or similar (i.e., the drying airflow requirements of the first barrel 100 and the second barrel 200 are the same or similar), the areas (i.e., cross-sectional areas or ventilation cross-sectional areas) of the first air outlet 431 and the second air outlet 432 can be the same (including approximately the same). Figure 4 As shown, the first air outlet 431 and the second air outlet 432 have the same area and shape, and their shape can be oblong (waist-shaped).

[0122] It is understandable that the size and shape of the air inlet and outlet can affect the airflow velocity and flow rate. By ensuring that the area difference between the first air inlet 411 and the second air inlet 412 corresponds to the pressure drop difference between the first air duct 421 and the second air duct 422, and that the area and shape of the first air outlet 431 and the second air outlet 432 are consistent, the drying airflow entering the first barrel 100 and the second barrel 200 can be made as uniform as possible, and the flow rate and velocity can be close or equal. This will make the drying effect of the first barrel 100 and the second barrel 200 similar, thus improving the user experience.

[0123] Preferably, the minimum cross-sectional area (i.e., ventilation cross-sectional area) of the first air duct 421 is not less than the area of ​​the first air inlet 411, and the minimum cross-sectional area of ​​the first air duct 421 is not less than the area of ​​the first air outlet 431. The minimum cross-sectional area (i.e., ventilation cross-sectional area) of the second air duct 422 is not less than the area of ​​the second air inlet 412, and the minimum cross-sectional area of ​​the second air duct 422 is not less than the area of ​​the second air outlet 432. It can be understood that satisfying the above requirements for the minimum cross-sectional area of ​​the air duct can avoid or reduce the impact on the flow rate and wind speed of the drying hot airflow due to the small cross-sectional area of ​​the air duct, so as to ensure that the drying hot airflow entering the first barrel 100 and the second barrel 200 is uniform and the drying effect is consistent or close.

[0124] Figure 6 The diagram shown is a simulation of the internal wind speed calculation of an isolation duct according to one embodiment of this application. Different colors of the lines in the diagram represent different wind speeds. Figure 6 The color gradually changes from blue to red, corresponding to a wind speed range of 5 m / s to 20 m / s. Simulation results of the internal wind speed calculation of the isolation duct according to one embodiment of this application show that the flow velocities at the first air outlet 431 and the second air outlet 432 are similar. When the areas and shapes of the first air outlet 431 and the second air outlet 432 are the same, the wind speed and flow rate of the drying hot air entering the first and second drums are similar or the same, allowing the first and second drums to simultaneously perform clothing drying operations with similar or identical efficiency.

[0125] Preferably, the first air inlet 411 and the second air inlet 412 can be adjacent to each other to facilitate their connection with the drying device 300. For example, Figure 3 As shown, the first air inlet 411 and the second air inlet 412 can be Figure 3 The first air inlet 411 and the second air inlet 412 are spaced apart in the vertical direction and can be connected to the drying device 300 through the same pipe (the end of the pipe can form a partition). The first air inlet 411 and the second air inlet 412 can also be separated by an isolation part 440. The first air inlet 411 and the second air inlet 412 can be spaced apart in the vertical direction of the multi-tube clothing processing device.

[0126] Preferred, such as Figure 5 As shown, the first air inlet 411 and the second air inlet 412 of the isolation duct 400 can be respectively equipped with anti-reverse structures to reduce or prevent water, foam, etc. from overflowing from the first tank 100 and the second tank 200 into the isolation duct. Specifically, the isolation duct 400 may include a first anti-reverse structure 451 and a second anti-reverse structure ( Figure 5 Only the first backstop structure 451 is shown in the diagram. The first backstop structure 451 can be disposed at the first air inlet 411, and the second backstop structure can be disposed at the second air inlet 412. Further, the isolation duct 400 can also form a backstop structure mounting groove to facilitate the installation of the backstop structure. For example, a first backstop structure mounting groove can be formed above the first air inlet 411 for installing the first backstop structure. A second backstop structure mounting groove 462 can be formed above the second air inlet 412 for installing the second backstop structure. Optionally, the backstop structure can be a structure that restricts deformation or restricts the rotational opening direction; for example, the backstop structure can include a baffle, spring, etc. The material of the backstop structure can be plastic, rubber, metal, etc.

[0127] The isolation duct 400 can be formed by splicing two or more shell structures. The shells can be connected by welding, snap-fit, or other methods.

[0128] Preferably, the walls of the first air duct 421 and the second air duct 422 can minimize sharp corners and adopt smooth arc surfaces as much as possible to reduce air resistance within the air ducts.

[0129] Optionally, the multi-drum garment handling device may also include more garment handling drums with drying functions (i.e., extended drying drums). There is no limitation on whether the extended drying drums also have washing and sterilization functions. Correspondingly, the multi-drum garment handling device can have a separate air duct connecting the drying unit 300 and the extended drying drums. Alternatively, the drying unit 300 can also be connected to the extended drying drums via an isolation air duct 400, which can further form structures such as an extended air inlet, an extended air duct, and an extended air outlet. The extended air duct is independent of the first air duct 421 and the second air duct 422.

[0130] It is understandable that, due to the limited size of the multi-tube clothing processing device, the internal components can be arranged relatively closely, and the isolation duct 400 can be shaped to avoid other components (such as the first tube 100 and the second tube 200) according to the actual layout requirements.

[0131] Furthermore, such as Figure 7 , Figure 8 , Figure 9 and Figure 10As shown, the isolation air duct assembly provided in this embodiment may further include a drying air interface 500. The drying device 300 can be connected to the first tank 100 via the drying air interface 500 through the first air duct 421, and the drying device 300 can be connected to the second tank 200 via the drying air interface 500 through the second air duct 422, so as to introduce the drying hot airflow into the first tank 100 and the second tank 200 respectively. The drying air interface 500 and the drying device 300 can be directly or indirectly connected. For example, the drying air interface 500 can be indirectly connected to the drying device 300 (the air outlet volute of the drying device 300) through a pipe.

[0132] like Figure 8 , Figure 9 and Figure 10 As shown, the drying air interface 500 can form an interface inlet 510, a diverter plate 520, and an interface outlet 530. The cross-sectional area of ​​the interface inlet 510 can be less than or equal to the cross-sectional area of ​​the interface outlet 530. It can be understood that having a cross-sectional area at least equal to the cross-sectional area of ​​the interface outlet can prevent pressure drop when airflow passes through the drying air interface. The diverter plate 520 can divide the interface inlet 510 into a first interface inlet 511 and a second interface inlet 512. The diverter plate 520 can also divide the interface outlet 530 into a first interface outlet 531 and a second interface outlet 532. That is, the diverter plate 520 can divide the drying air interface 500 into two independent interface channels: the first interface channel (from the first interface inlet 511 to the first interface outlet 531) and the second interface channel (from the second interface inlet 512 to the second interface outlet 532).

[0133] The first air outlet 531 of the interface can be connected to the first air duct 421, that is, the first interface channel can be connected to the first air duct 421. The second air outlet 532 of the interface can be connected to the second air duct 422, that is, the second interface channel can be connected to the second air duct 422.

[0134] In the embodiments of this application, the pressure drop of the first air duct 421 is greater than that of the second air duct 422. It is understood that the first and second air ducts defined herein do not constitute a limitation on the technical solution.

[0135] Based on the pressure drop difference between the first air duct 421 and the second air duct 422, to ensure uniform airflow into the first barrel 100 and the second barrel 200, the cross-sectional areas of the first air inlet 511 and the second air inlet 512 can be made to correspond to the pressure drop difference (in the embodiments of this application, the cross-section can be a surface perpendicular to the direction of the drying airflow). That is, the cross-sectional area of ​​the first air inlet 511 can be larger than that of the second air inlet 512. The specific area difference between the first air inlet 511 and the second air inlet 512 can be calculated based on the actual usage scenario combined with flow channel parameters, drying airflow parameters, etc. It can be understood that, in order to create an area difference between the first air inlet 511 and the second air inlet 512, the flow divider 520 can be offset. For example, when the air inlet 510 is circular, the flow divider 520 can be relatively offset from the diameter of the air inlet.

[0136] To reduce the pressure drop of the drying airflow within the drying air interface after it enters the first air inlet 511 or the second air inlet 512, the cross-sectional area of ​​the first air inlet 511 can be less than or equal to the cross-sectional area of ​​the first air outlet 531, and the cross-sectional area of ​​the second air inlet 512 can be less than or equal to the cross-sectional area of ​​the second air outlet 532. Furthermore, to reduce the pressure drop of the drying airflow within the isolation duct 200, the cross-sectional area of ​​the first air inlet 511 can also be less than the minimum cross-sectional area of ​​the first duct 421, and the cross-sectional area of ​​the second air inlet 512 can also be less than the minimum cross-sectional area of ​​the second duct 422, ensuring that the flow rate and velocity of the drying air entering the drying air interface 500 are not affected by the reduced cross-sectional area.

[0137] For example, such as Figure 8 , Figure 9 and Figure 10 As shown, the first air inlet 511 and the second air inlet 512 of the interface can be Figure 1 and Figure 7 The air inlets 511 and 512 are spaced apart in the vertical direction of the multi-tube clothing processing device.

[0138] A transition surface can be formed between the first air inlet 511 and the first air outlet 531, and between the second air inlet 512 and the second air outlet 532. Preferably, based on the pressure drop difference between the first flow channel 210 and the second flow channel 220, the transition surface between the first air inlet 511 and the first air outlet 531 can also differ from the transition surface between the second air inlet 512 and the second air outlet 532; for example, the curvature of the two transition surfaces can be adjusted. The inner surfaces of the transition surfaces can all be smooth to reduce air resistance inside the drying air interface 500. For example, the drying air interface 500 can be formed in an irregular funnel or horn shape.

[0139] Preferably, the end of the diverter plate 520 near the interface air inlet 510 can form a first diverting surface 521 and a second diverting surface 522, both of which form an angle with the direction of the drying airflow (i.e., the axial direction of the drying air interface). The first diverting surface 521 and the second diverting surface 522 can intersect and form a certain angle, and the line of intersection of the first diverting surface 521 and the second diverting surface 522 is the edge of the diverter plate 520 near the interface air inlet 510. The first diverting surface 521 can be close to the interface first air inlet 511, and the second diverting surface 522 can be close to the interface second air inlet 512. It is understandable that the first diversion surface 521 and the second diversion surface 522 at the air inlet 510 can guide and divert the drying airflow entering the first interface channel and the second interface channel, respectively. The slope of the diversion surface (the angle between the diversion surface and the airflow direction, i.e., the angle between the diversion surface and the drying air interface) and the guiding length (the length along the airflow direction, i.e., the axial length of the drying air interface 500) can adjust the drying airflow.

[0140] The shape of the main body of the diverter plate 520 can be set according to the actual needs of the drying air interface 500. For example, the shape of the diverter plate 520 can be a flat plate (the upper surface 523 and the lower surface 524 of the diverter plate are parallel to each other), a wedge shape (the upper surface 523 and the lower surface 524 of the diverter plate form a certain angle), etc. The upper surface 523 and the lower surface 524 of the diverter plate can be flat plates, arc plates, etc. It can be understood that the "upper surface 523" and 524 here refer to the surfaces of the main body of the diverter plate 520, which can be connected to the first diverting surface 521 and the second diverting surface 522, respectively.

[0141] Furthermore, based on the pressure drop difference between the first air duct 421 and the second air duct 422, in order to ensure uniform air intake for the first barrel 100 and the second barrel 200, the slope and guide length of the first diversion surface 521 and the second diversion surface 522 can be made different. That is, the slope of the first diversion surface 521 can be less than the slope of the second diversion surface 522, and the guide length of the first diversion surface 521 can be greater than the guide length of the second diversion surface 522.

[0142] Preferred, such as Figure 8 , Figure 9 and Figure 10 As shown, a fixing part 540 can be formed on the outer periphery of the air outlet 530 of the drying air interface 500. The number and type of fixing devices included in the fixing part 540 are not limited; for example, the fixing part 540 can be a bolt fixing part, a clip, a slot, a clamp, etc. For example, the fixing part 540 may include four lug-type fixing parts 541 distributed on the outer periphery of the air outlet 530, which can be used to connect to the isolation duct 200 by bolts.

[0143] Preferably, a sealing ring groove 550 can be formed on the outer periphery of the air outlet 530 of the drying air interface 500, which can be used to accommodate the sealing ring. It can be understood that setting a sealing ring between the drying air interface 500 and the isolation duct 200 can enhance the airtightness between the drying air interface 500 and the isolation duct 200.

[0144] Optionally, the drying air interface 500 can also form an extended interface channel, that is, the drying air interface 500 can be provided with an extended diverter plate. The extended diverter plate can further divide the interface air inlet 510 into an extended air inlet, and the extended diverter plate can further divide the interface air outlet 530 into an extended air outlet. Embodiments of this application also provide a multi-tube clothing processing device, which may include the above-mentioned isolation duct assembly for a multi-tube clothing processing device, as well as a first tub 100, a second tub 200, and a drying device 300. The first tub 100 can be connected to a first air outlet 431, and the second tub can be connected to a second air outlet 432. The drying device 300 can be directly or indirectly connected to the first air inlet 411 and the second air inlet 412, so that the drying hot airflow generated in the drying device 300 enters the first tub 100 and the second tub 200 respectively through the isolation duct 400.

[0145] Preferably, the first bucket 100 and the second bucket 200 can be water tanks for a washer-dryer combo.

[0146] Preferably, the first tub 100 and the second tub 200 can be arranged side by side with the same opening direction, and the first tub 100 and the second tub 200 can be the same size. The isolation air duct 400 can be set on one side of the opening of the first tub 100 and the opening of the second tub 200, especially above the opening of the first tub 100 and the opening of the second tub 200 (i.e., the first air outlet 431 is connected to the upper side of the peripheral wall of the opening of the first tub 100, and the second air outlet 432 is connected to the upper side of the peripheral wall of the opening of the second tub 200), so that the drying hot airflow is introduced from the opening of the clothes processing tub, avoiding the filter structure inside the clothes processing tub from affecting the flow of the drying hot airflow.

[0147] The multi-drum laundry handling device may further include an exhaust pipe 600 for discharging the airflow (e.g., the humid airflow generated during drying) from the first drum 100 and the second drum 200. One end of the exhaust pipe 600 may be connected to the first drum 100 and the second drum 200 respectively, and the other end of the exhaust pipe 600 may be connected to a drying device to heat the airflow and form a hot drying airflow for recycling. Preferably, the exhaust pipe 600 may be connected to the bottom of the first drum 100 (i.e., the side of the first drum 100 opposite to the opening) and the bottom of the second drum 200 (i.e., the side of the second drum 200 opposite to the opening). In particular, the exhaust pipe 600 may be connected to the bottom of the drums and at least partially positioned above the first drum 100 and the second drum 200 to prevent water, foam, etc., from entering the exhaust pipe 600. The air outlet pipe 600 and the isolation air duct can be offset in the axial direction of the clothes processing drum (the first drum 100 and the second drum 200 are parallel to each other) (that is, the air outlet pipe 600 and the isolation air duct are located at different positions in the axial direction) so that the air outlet pipe 600 and the isolation air duct 400 do not interfere with each other above the first drum 100 and the second drum 200, which can save the internal space of the multi-drum clothes processing device.

[0148] like Figure 11 As shown, the air outlet pipe 600 may include a first air outlet branch 610, a second air outlet branch 620, and a main air outlet pipe 630. The first tank 100 and the second tank 200 may be arranged side-by-side in the horizontal direction. The first air outlet branch 610 may connect the first tank 100 and the main air outlet pipe 630, and the second air outlet branch 620 may connect the second tank 200 and the main air outlet pipe 630. That is, the first air outlet branch 610 and the second air outlet branch 6222 can allow the air from both the first tank 100 and the second tank 200 to be jointly introduced into the main air outlet pipe 630.

[0149] Preferably, the main air outlet 630 and the isolation air duct 400 are staggered in the front-to-back direction of the multi-tube clothing processing device.

[0150] The main air outlet duct 630 can form a filter receiving cavity 631, which can be equipped with a filter to filter the airflow entering the main air outlet duct 630 (especially to filter fibers, hair and other impurities in the airflow) and prevent impurities from entering the drying device 300.

[0151] Preferably, the filter receiving cavity 631 and the isolation air duct 400 are offset in the front-rear direction of the multi-drum garment processing device. In particular, the isolation air duct 400 can be closer to the front of the multi-drum garment processing device than the filter receiving cavity 631. The above arrangement can make full use of the gap space between the multiple garment processing drums to install pipelines, and can use a single filter to filter the airflow from the multiple garment processing drums.

[0152] Preferably, at least a portion of the structure of the air outlet duct 600 can be disposed between the first tank 100 and the second tank 200, and in particular, at least a portion of its main air outlet duct 630 can be disposed between the first tank 100 and the second tank 200, so as to make reasonable use of the space between the first tank 100 and the second tank 200.

[0153] The filter receiving cavity 631 may have an opening that faces the radially outer side of the first tub 100 and the radially outer side of the second tub 200 (especially above the first and second tubs), or the opening of the filter receiving cavity 631 may also face the front side of the multi-tub laundry treatment device (the opening direction of the laundry treatment tub) to facilitate cleaning and replacement of the filter.

[0154] Preferably, the first air outlet branch 610 is provided with a first air outlet control unit for controlling the on / off state of the first air outlet branch 610. The second air outlet branch 620 is provided with a second air outlet control unit for controlling the on / off state of the second air outlet branch 620.

[0155] Preferably, the first vent branch 610 can be connected to the side of the first barrel 100 away from the barrel opening (i.e., the bottom of the first barrel), and the second vent branch 620 can be connected to the side of the second barrel 200 away from the barrel opening (i.e., the bottom of the second barrel).

[0156] The multi-tube garment processing device may also include more garment processing tubes, such as a third tube disposed above the first tube 100 and the second tube 200, and a fourth tube disposed below the first tube 100 and the second tube 200. The diameter of the third tube and the fourth tube may be larger than the diameter of the first tube 100 and the second tube 200, for example, the diameter of the third tube and the fourth tube may be approximately twice the diameter of the first tube 100 and the second tube 200.

[0157] It is understandable that multi-drum garment handling devices can evenly deliver hot airflow for drying to two or more garment handling drums, but they do not force two or more garment handling drums to perform drying operations at the same time. In other words, users can choose whether one or more garment handling drums perform drying operations at the same time.

[0158] The following is a brief description of some of the beneficial effects of the above-described embodiments of this application.

[0159] The isolation duct assembly for a multi-drum garment processing device provided in this application is applied to a multi-drum garment processing device, enabling the simultaneous and uniform introduction of drying air into multiple garment processing drums through multiple air supply ducts of the isolation duct. This allows at least two garment processing drums of the multi-drum garment processing device to perform drying operations simultaneously. Using a single drying device to simultaneously dry multiple garment processing drums saves energy, reduces garment processing time, and improves the user experience. Furthermore, each independent air supply duct of the isolation duct can be individually equipped with a backflow preventer, effectively preventing water overflow, air leakage, and other phenomena between multiple air supply ducts.

[0160] It is understood that, in this application, when the number of parts or components is not specifically limited, the number can be one or more, where multiple refers to two or more. For cases where the number of parts or components shown in the drawings and / or described in the specification is, for example, two, three, four, etc., this specific number is generally exemplary and not restrictive, and can be understood as multiple, i.e., two or more; however, this does not mean that this application excludes the case of one.

[0161] It should be understood that the above embodiments are merely exemplary and are not intended to limit this application. Those skilled in the art can make various modifications and changes to the above embodiments under the teachings of this application without departing from the scope of this application.
