Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of clothes processing, and particularly relates to a drying air inlet assembly for a multi-cylinder clothes processing device and a multi-cylinder clothes processing device. BACKGROUND

[0002] It is an important development direction of the current multi-cylinder clothes processing device to enable multiple clothes processing cylinders to simultaneously perform clothes drying operations. Due to cost and space limitations of the multi-cylinder clothes processing device, only one drying device can be arranged in the multi-cylinder clothes processing device, and the drying device is connected to multiple clothes processing barrels through a drying air pipe. In related prior art, a pipe selection structure is usually used to connect the drying device and the multiple clothes processing barrels, that is, according to actual selection of a user, the multi-cylinder clothes processing device controls the pipe selection structure to separately connect corresponding clothes processing barrels and the drying device.

[0003] The technical solution described above for connecting the clothes processing barrels and the drying device through the pipe selection structure cannot simultaneously connect two clothes processing barrels and the drying device, that is, the two clothes processing barrels cannot simultaneously perform drying operations. Moreover, the pipe lengths and pipe bending conditions of the drying air pipes connected to different clothes processing barrels are inconsistent, which causes actual inlet air efficiency of the drying air of different clothes processing barrels to be inconsistent, and cannot better meet the use requirements of the user. Therefore, a technical solution capable of simultaneously performing drying operations on two clothes processing barrels and having good inlet air uniformity is urgently needed. CONTENT OF THE INVENTION

[0004] The present application is made in view of the above-mentioned state of the prior art. The purpose of the present application is to provide a drying air inlet assembly for a multi-cylinder clothes processing device, which can set the first inlet and the second inlet to different sizes according to pressure drop characteristics of different downstream air ducts through a drying air interface, so as to make drying air flow uniformly into two clothes processing barrels.

[0005] The present application also provides a multi-cylinder clothes processing device comprising the above-mentioned drying air inlet assembly.

[0006] The present application provides a drying air inlet assembly for a multi-cylinder clothes processing device, which is used to introduce drying air into multiple clothes processing barrels. The drying air inlet assembly comprises a drying air interface, a first air duct and a second air duct, the pressure drop of the first air duct is greater than the pressure drop of the second air duct,

[0007] The drying air interface is formed with an inlet, a flow distribution plate and an outlet, the flow distribution plate extends from the inlet to the outlet,

[0008] The cross-sectional area of the inlet is less than or equal to the cross-sectional area of the outlet,

[0009] The shunt plate divides the air inlet into a first air inlet and a second air inlet, and divides the air outlet into a first air outlet and a second air outlet, the first air outlet is communicated with the first air duct, and the second air outlet is communicated with the second air duct,

[0010] The cross-sectional area of the first air inlet is greater than the cross-sectional area of the second air inlet.

[0011] The cross-sectional area of the first air inlet is greater than the cross-sectional area of the second air inlet.

[0012] In at least one possible implementation, the cross-sectional area of the first air inlet is less than the minimum cross-sectional area of the first air duct, and the cross-sectional area of the second air inlet is less than the minimum cross-sectional area of the second air duct.

[0013] Making the cross-sectional area of the air inlet less than the minimum cross-sectional area of the air duct can avoid the influence of the flow and flow rate of the drying air after entering the drying air interface due to the decrease of the cross-sectional area when passing through the air duct, and unnecessary pressure drop.

[0014] In at least one possible implementation, the cross-sectional area of the first air inlet is less than or equal to the cross-sectional area of the first air outlet, and the cross-sectional area of the second air inlet is less than or equal to the cross-sectional area of the second air outlet.

[0015] Making the cross-sectional area of the air inlet less than or equal to the cross-sectional area of the air outlet can reduce or avoid the pressure drop of the drying air in the drying air interface.

[0016] In at least one possible implementation, the first air duct and the second air duct are formed in a shell formed isolation air duct, and the isolation air duct includes an isolation part, the isolation part separates the first air duct and the second air duct, and the first air duct and the second air duct are independent of each other.

[0017] Separating the first air duct and the second air duct to be independent of each other can avoid the influence of the drying air in the two air ducts on each other.

[0018] In at least one possible implementation, an end of the shunt plate close to the air inlet forms a first shunt surface and a second shunt surface,

[0019] The first flow distribution surface and the second flow distribution surface are both formed at an angle with respect to the axis of the drying air interface,

[0020] The first flow distribution surface is close to the first air inlet, and the second flow distribution surface is close to the second air inlet.

[0021] The end of the flow distribution plate is formed with two flow distribution surfaces, which can guide the flow of drying air and distribute the flow of drying air, so that the drying air can more smoothly enter the first air duct and the second air duct according to the preset flow difference.

[0022] In at least one possible implementation, the slope of the first flow distribution surface is smaller than the slope of the second flow distribution surface.

[0023] The guiding length of the first flow distribution surface is greater than the guiding length of the second flow distribution surface.

[0024] The above parameters can make the flow of drying air entering the first air duct greater than the flow of drying air entering the second air duct, so as to adapt to the greater pressure drop of the first air duct.

[0025] In at least one possible implementation, the drying air interface further comprises a fixing portion, which is arranged on the outer periphery of the air outlet.

[0026] The fixing portion is arranged on the outer periphery of the air outlet, which facilitates the connection of the drying air interface with other structures, especially the connection with the air duct structure.

[0027] In at least one possible implementation, the drying air interface further comprises a sealing ring groove, which is formed on the outer periphery of the air outlet and used for accommodating a sealing ring.

[0028] The sealing ring added to the air outlet of the drying air interface can improve the sealing between the drying air interface and the structure connected thereto, preventing or reducing the overflow of the drying air flow.

[0029] In at least one possible implementation, the upper surface of the flow distribution plate is parallel to or forms an angle with the lower surface of the flow distribution plate, and the upper surface of the flow distribution plate and the lower surface of the flow distribution plate are flat plates or arc-shaped plates.

[0030] The above content gives the preferred shape structure of the flow distribution plate, which can be adjusted as needed to make the guiding and distributing effect of the drying air interface more ideal.

[0031] The present application also provides a multi-cylinder clothes treatment device, which comprises a first barrel, a second barrel and a drying device; and the aforementioned drying air inlet assembly for the multi-cylinder clothes treatment device, the end of the first air duct forms a first air duct outlet, and the end of the second air duct forms a second air duct outlet,

[0032] The first barrel is connected with the first air duct outlet, the second barrel is connected with the second air duct outlet, and the drying device is directly or indirectly connected with the first air inlet and the second air inlet, so that the drying hot air flow formed in the drying device can enter the first barrel and the second barrel respectively through the drying air inlet assembly.

[0033] The multi-barrel clothes processing device can realize uniform drying air flow into the first barrel and the second barrel based on the aforementioned drying air inlet assembly, so that the clothes drying efficiency of the first barrel and the second barrel is consistent or close.

[0034] In at least one possible implementation, the drying device connects the first air inlet and the second air inlet via a single air duct,

[0035] The first air inlet and the second air inlet are separated by the shunt plate in the shell, and the first air outlet and the second air outlet are also separated by the shunt plate,

[0036] The first barrel and the second barrel are arranged side by side and have the same opening direction, the first air duct outlet is connected with the upper side of the barrel opening peripheral wall of the first barrel, and the second air duct outlet is connected with the upper side of the barrel opening peripheral wall of the second barrel, so that the drying hot air flow enters the first barrel and the second barrel from the upper side of the barrel opening of the first barrel and the upper side of the barrel opening of the second barrel respectively.

[0037] The drying air flow enters the clothes processing barrel from the upper side of the barrel opening peripheral wall of the clothes processing barrel, which can make the drying air flow contact or flow through the clothes to be dried as much as possible, thereby improving the drying effect of the clothes processing barrel.

[0038] In at least one possible implementation, the multi-barrel clothes processing device further comprises an air outlet duct connected with the barrel bottom of the first barrel and the barrel bottom of the second barrel, and the air outlet duct is also connected with the drying device to form a drying air flow circulation,

[0039] The air outlet duct is at least partially arranged above the first barrel and the second barrel, the drying air inlet assembly is at least partially arranged above the first barrel and the second barrel, and the air outlet duct and the drying air inlet assembly are staggered in the axial direction of the first barrel and the axial direction of the second barrel.

[0040] This scheme can realize that the drying air flow enters from the barrel opening and flows out from the barrel bottom, which can maximize the drying air flow through all or most of the clothes to be dried, so as to fully utilize the drying air flow and improve the clothes drying effect.

[0041] The multi-cylinder laundry treating device drying air inlet assembly and the multi-cylinder laundry treating device provided by the application set a flow distribution plate inside the drying air interface to separate the drying air interface into a first air inlet and a second air inlet. According to the pressure drop characteristics of different air ducts connected downstream of the drying air interface, the first air inlet and the second air inlet can be set to different sizes. Different from the ordinary uniform distribution interface, the drying air interface provided by the application can adjust the parameters of the interface according to the pressure drop characteristics of the downstream air duct. Compared with the larger drying air flow difference under the condition of the uniform distribution interface, the drying air interface can realize uniform introduction of drying air flow into two laundry treating barrels at the same time. Further, the at least two laundry treating barrels of the multi-cylinder laundry treating device can simultaneously perform drying operation and the drying air flow inlet distribution consistency is good. The multi-cylinder laundry treating device provided by the application can realize simultaneous drying operation of multiple laundry treating barrels using only one drying device, which can save energy, reduce the operation time of the laundry treating device and improve the user experience.

[0077] The exemplary embodiments of the present application are described herein below with reference to the accompanying drawings. It is to be understood that the specific description is merely for the purpose of illustration and that the application is not limited to the specific embodiments described herein.

[0078] The embodiments of the present application provide a drying air inlet assembly for a multi-drum laundry treating apparatus (hereinafter, sometimes referred to as "inlet assembly"), which can include a drying air interface 100 and first and second air ducts 210 and 220. The drying air interface 100 can be connected to the first and second air ducts 210 and 220. The first and second air ducts 210 and 220 are independent air flow paths, and their specific structural forms are not limited, and for example, the first and second air ducts 210 and 220 can be hoses, metal pipes, etc.

[0079] Preferably, as shown in Figure 5 and Figure 6 , the first and second air ducts 210 and 220 can be integrally formed in the isolation air duct 200, and in particular, can be formed in an isolation air duct formed by a housing, that is, the first and second air ducts 210 and 220 can be formed in the isolation air duct 200.

[0080] As shown in Figure 1 , the drying air interface 100 and the isolation air duct 200 can be provided in a multi-drum laundry treating apparatus having a laundry drying function. For example, as shown in Figure 1 , the multi-drum laundry treating apparatus to which the drying air interface 100 is applied can include a drying apparatus 300 and first and second drums 400 and 500. It can be understood that the first and second drums 400 and 500 herein can be laundry treating drums having a laundry drying function, and in particular, can be washing and drying integrated (having a washing and drying function) water containing drums.

[0081] The drying apparatus 300 can heat air to form a hot air flow capable of drying laundry, and the drying apparatus 300 can connect the first drum 400 via the first air duct 210 and the second drum 500 via the second air duct 220 through the drying air interface 100 to pass the drying hot air flow into the first and second drums 400 and 500, respectively. The drying air interface 100 can be directly or indirectly connected to the drying apparatus 300, and for example, as shown in Figure 1 , the drying air interface 100 can be indirectly connected to the drying apparatus 300 (exhaust air scroll of the drying apparatus 300) through a pipe.

[0082] As shown in Figure 2 , Figure 3 and Figure 4As shown, the drying air interface 100 can form an air inlet 110, a distribution plate 120, and an air outlet 130. The cross-sectional area of the air inlet 110 can be less than or equal to the cross-sectional area of the air outlet 130. It can be understood that the cross-sectional area of the air outlet is not less than the cross-sectional area of the air inlet, which can make the air flow through the drying air interface not prone to form a pressure drop. The distribution plate 120 can separate the air inlet 110 to form a first air inlet 111 and a second air inlet 112, and can also separate the air outlet 130 to form a first air outlet 131 and a second air outlet 132. That is, the distribution plate 120 can separate the drying air interface 100 to form two independent interface channels. The first air inlet 111 to the first air outlet 131 can form a first interface channel, and the second air inlet 112 to the second air outlet 132 can form a second interface channel.

[0083] The first air outlet 131 can be connected to the first air duct 210, that is, the first interface channel can be connected to the first air duct 210. The second air outlet 132 can be connected to the second air duct 220, that is, the second interface channel can be connected to the second air duct 220. Due to the internal structure of the multi-cylinder clothes treatment device, the shapes, lengths, structures, etc. of the first air duct 210 and the second air duct 220 are often different. For example, Figure 6 As shown, the first air duct 210 is relatively long and has a partial bending structure. It can be understood that the air duct with a relatively long length and a certain obstacle structure (such as bending, corner, internal protrusion, etc.) has a relatively large pressure drop (pressure drop of fluid flowing in the pipe due to energy loss). The pressure drops of the air ducts are different, which can cause the air outlet flow rate and air outlet flow rate of each air duct to be different, and further cause the drying efficiency of the multiple clothes treatment barrels to be inconsistent, thereby affecting the user experience.

[0084] In the embodiments of the present application, the air duct with a larger pressure drop is the first air duct, and the air duct with a smaller pressure drop is the second air duct, that is, the pressure drop of the first air duct 210 is greater than that of the second air duct 220. It can be understood that the first air duct and the second air duct defined herein do not form a limitation on the technical solutions.

[0085] Based on the pressure drop difference between the first air duct 210 and the second air duct 220, to ensure uniform airflow into the first barrel 400 and the second barrel 500, the cross-sectional areas of the first air inlet 111 and the second air inlet 112 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 111 can be larger than that of the second air inlet 112. The specific area difference between the first air inlet 111 and the second air inlet 112 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 111 and the second air inlet 112, the flow divider 120 can be offset. For example, when the air inlet 110 is circular, the flow divider 120 can be relatively offset from the diameter of the air inlet.

[0086] To avoid or reduce the pressure drop of the drying airflow within the drying air interface after it enters the first air inlet 111 or the second air inlet 112, the cross-sectional area of ​​the first air inlet 111 can be less than or equal to the cross-sectional area of ​​the first air outlet 131, and the cross-sectional area of ​​the second air inlet 112 can be less than or equal to the cross-sectional area of ​​the second air outlet 132. Furthermore, to reduce the pressure drop of the drying airflow within the isolation duct 200, the cross-sectional area of ​​the first air inlet 111 can be less than the minimum cross-sectional area of ​​the first duct 210, and the cross-sectional area of ​​the second air inlet 112 can be less than the minimum cross-sectional area of ​​the second duct 220, so that the flow rate and velocity of the drying air entering the drying air interface 100 are not affected by the reduced cross-sectional area.

[0087] For example, as shown in the figure Figure 2 , Figure 3 , Figure 6 As shown, the first air inlet 111 and the second air inlet 112 can be Figure 2 , Figure 3 and Figure 6 The first air inlet 111 and the second air inlet 112 are spaced apart in the vertical direction of the multi-tube clothing processing device.

[0088] A transition surface can be formed between the first air inlet 111 and the first air outlet 131, and between the second air inlet 112 and the second air outlet 132. 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 111 and the first air outlet 131 and the transition surface between the second air inlet 112 and the second air outlet 132 can also be different; for example, the curvature of the two transition surfaces can be adjusted. The inner surfaces of the transition surfaces can all be smooth surfaces to reduce air resistance inside the drying air interface 100. For example, the drying air interface 100 can be formed in an irregular funnel shape or a horn shape.

[0089] Preferably, as shown in Figure 2 and Figure 3 As shown in the drawings, the end of the flow distribution plate 120 close to the air inlet 110 can form a first flow distribution surface 121 and a second flow distribution surface 122, both of which form an angle with the drying air flow direction (i.e. the axial direction of the drying air interface). The first flow distribution surface 121 and the second flow distribution surface 122 can intersect and form a certain angle, and the intersection line of the first flow distribution surface 121 and the second flow distribution surface 122 is the edge of the flow distribution plate 120 close to the air inlet 110. The first flow distribution surface 121 can be close to the first air inlet 111, and the second flow distribution surface 122 can be close to the second air inlet 112. It can be understood that the first flow distribution surface 121 and the second flow distribution surface 122 at the air inlet 110 can respectively guide and distribute the drying air flow entering the first interface channel and the second interface channel, and the slope of the flow distribution surface (the angle between the flow distribution surface and the air flow direction, i.e. the angle between the flow distribution surface and the drying air interface) and the guide length (the length along the air flow direction, i.e. the axial length of the drying air interface 100) can adjust the drying air flow.

[0090] The shape of the main body of the flow distribution plate 120 can be set according to the actual needs of the drying air interface 100. For example, the shape of the flow distribution plate 120 can be a flat plate shape (the upper surface 123 of the flow distribution plate and the lower surface 124 of the flow distribution plate are parallel to each other), a wedge shape (the upper surface 123 of the flow distribution plate and the lower surface 124 of the flow distribution plate form a certain angle), etc. The upper surface 123 of the flow distribution plate and the lower surface 124 of the flow distribution plate can be flat plates, arc-shaped plates, etc. It can be understood that here "upper surface 123", 124 is the surface of the main body of the flow distribution plate 120, which can be connected with the first flow distribution surface 121 and the second flow distribution surface 122 respectively.

[0091] Further, based on the pressure drop difference between the first air duct 210 and the second air duct 220, in order to make the air inlets of the first barrel 400 and the second barrel 500 uniform, the slope of the first flow distribution surface 121 and the second flow distribution surface 122 can be different from the guide length. That is, the slope of the first flow distribution surface 121 can be smaller than the slope of the second flow distribution surface 122, and the guide length of the first flow distribution surface 121 can be greater than the guide length of the second flow distribution surface 122.

[0092] Preferably, as shown in Figure 2 , Figure 3 and Figure 4As shown, the outer periphery of the air outlet 130 of the drying air interface 100 can form a fixing portion 140. The fixing portion 140 includes fixing devices without limitation in number, and the fixing portion can be of any type, for example, the fixing portion 140 can be a bolt fixing portion, a buckle, a clamping groove, a hoop, etc. Exemplarily, the fixing portion 140 can include four ear-shaped fixing portions 141 distributed on the outer periphery of the air outlet 130, which can be used to be bolted with the isolation air duct 200.

[0093] Preferably, the outer periphery of the air outlet 130 of the drying air interface 100 can also form a sealing ring groove 150, which can be used to accommodate a sealing ring. It can be understood that the sealing ring arranged between the drying air interface 100 and the isolation air duct 200 can enhance the air tightness between the drying air interface 100 and the isolation air duct 200.

[0094] Optionally, the drying air interface 100 can also form an extended interface passage, i.e., the drying air interface 100 can be provided with an extended shunt plate, which can further divide the air inlet 110 into an extended air inlet and the air outlet 130 into an extended air outlet.

[0095] As shown in Figure 5 and Figure 6 The end of the first air duct 210 of the isolation air duct 200 can form a first air duct outlet 211, and the end of the second air duct 220 can form a second air duct outlet 221. The first air duct 210 and the second air duct 220 can be provided with a separation portion to separate the first air duct 210 from the second air duct 220. The first air duct outlet 211 can be connected to the first barrel 400, and the second air duct outlet 221 can be connected to the second barrel 500 to respectively introduce drying air flow into the first barrel 400 and the second barrel 500.

[0096] It can be understood that separating the first air duct 210 and the second air duct 220 from each other can make the gas flow in them not easily affect each other, and also can avoid water or foam flowing from one of the first barrel 400 and the second barrel 500 into the other through the isolation air duct 200 when one of them overflows water or foam.

[0097] Preferably, the areas (i.e., cross-sectional areas or ventilation cross-sectional areas) of the first air duct outlet 211 and the second air duct outlet 221 can be the same (including substantially the same). The shapes of the first air duct outlet 211 and the second air duct outlet 221 can be the same (including substantially the same). For example, the areas and shapes of the first air duct outlet 211 and the second air duct outlet 221 are the same, and their shapes can be oblong (waist-shaped). It is understood that keeping the areas and shapes of the first air duct outlet 211 and the second air duct outlet 221 consistent can make the drying airflow entering the first barrel 400 and the second barrel 500 as uniform as possible, and the flow rate and velocity close or equal, thereby making the drying effects of the first barrel 400 and the second barrel 500 similar and improving the user experience.

[0098] Figure 7 and Figure 8 The diagram shown is a simulation of the internal wind speed calculation of an air intake assembly according to one embodiment of this application. Different colors of the lines in the diagram represent different wind speeds. Figure 7 and Figure 8 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 air inlet assembly according to one embodiment of this application show that the flow velocities at the first air duct outlet 211 and the second air duct outlet 221 are similar. By adjusting the cross-sectional areas of the first air inlet 111 and the second air inlet 112 based on the pressure drop of the first air duct 210 and the second air duct 220, the wind speed and flow rate of the drying hot airflow entering the first and second drums can be made similar or the same, thereby enabling the first and second drums to simultaneously perform clothing drying operations with similar or identical efficiency.

[0099] Figure 9 This is a comparison of the air resistance (pressure drop characteristic) curves of the air intake assembly of this embodiment and a conventional air intake assembly (without a splitter plate and without changing the air inlet size according to the pressure drop difference of different air ducts). In the figure, the dashed line represents the data of the conventional air intake assembly, and the solid line represents the data of the air intake assembly of this embodiment. As can be seen from the comparison in the figure, the air intake assembly provided in this embodiment can effectively reduce air resistance.

[0100] Figure 10 This diagram compares the airflow distribution (drying airflow into the first drum 400 and the second drum 500) of the air inlet assembly in this embodiment with that of a conventional air inlet assembly (without a flow divider and without adjusting the inlet size according to pressure drop differences in different air ducts). The dashed lines represent data from the conventional air inlet assembly, while the solid lines represent data from the air inlet assembly of this embodiment. The comparison shows that the air inlet assembly provided in this embodiment can improve the uniformity of the drying airflow entering the first drum 400 and the second drum 500, making the drying efficiencies of the first drum 400 and the second drum 500 more similar.

[0101] The isolation air duct 200 can be formed by splicing two or more half-shell structures. The half-shells can be connected by welding, buckle connection, or the like.

[0102] Preferably, the walls of the first air duct 210 and the second air duct 220 can have as few sharp corners as possible and as many smooth arcs as possible to reduce air resistance in the air ducts.

[0103] Optionally, the multi-barrel laundry treatment device can further include more laundry treatment barrels with drying function (i.e., extended drying barrels). Here, it is not limited whether the extended drying barrels also have washing, sterilization, or the like. Correspondingly, the multi-barrel laundry treatment device can additionally separately provide an air supply air duct connected to the drying device 300 and the extended drying barrels. Alternatively, the drying device 300 can be connected to the extended drying barrels via the drying air interface 100 and the isolation air duct 200. The isolation air duct 200 can further form an extended air duct or the like. The extended air duct and the first air duct 210, and the extended air duct and the second air duct 220 can be independent of each other.

[0104] It can be understood that, due to the limitation of the equipment volume of the multi-barrel laundry treatment device, the arrangement of the components inside can be relatively compact. The air inlet assembly (especially the isolation air duct 200) can form a shape that can avoid other components (e.g., the first barrel 400 and the second barrel 500) according to the actual arrangement form.

[0105] The embodiments of the present application also provide a multi-barrel laundry treatment device, which can include the above-mentioned drying air inlet assembly for a multi-barrel laundry treatment device, and a first barrel 400, a second barrel 500, and a drying device 300. The first barrel 400 can be connected to the first air duct outlet 211, and the second barrel can be connected to the second air duct outlet 221. The drying device 300 can be directly or indirectly connected to the first air inlet 111 and the second air inlet 112, so that the drying hot air flow formed in the drying device 300 enters the first barrel 400 and the second barrel 500 via the isolation air duct 200, respectively. Here, the drying device 300 can be connected to the first air inlet 111 and the second air inlet 112 via a single air pipe.

[0106] Preferably, the first barrel 400 and the second barrel 500 can be integrated washing and drying water barrels.

[0107] Preferably, the first drum 400 and the second drum 500 can be arranged side by side and have the same opening direction. The first drum 400 and the second drum 500 can have the same size. The air inlet assembly can be arranged at one side of the drum opening of the first drum 400 and the drum opening of the second drum 500, in particular, can be arranged above the one side of the drum opening of the first drum 400 and the drum opening of the second drum 500 (i.e., the first air duct outlet 211 is connected to the upper side of the peripheral wall of the drum opening of the first drum 400, and the second air duct outlet 221 is connected to the upper side of the peripheral wall of the drum opening of the second drum 500), so that the drying hot air flow is introduced from the drum opening of the laundry treatment drum, and the filtering structure inside the laundry treatment drum does not affect the flow of the drying hot air flow.

[0108] The multi-drum laundry treatment device can further comprise an air outlet duct 600 for discharging the air flow (e.g., the moisture flow formed by drying the laundry) in the first drum 400 and the second drum 500. One end of the air outlet duct 600 can be connected to the first drum 400 and the second drum 500, respectively, and the other end of the air outlet duct 600 can be connected to the drying device to heat the air flow to form the drying hot air flow for recycling. Preferably, the air outlet duct 600 can be connected to the bottom of the first drum 400 (i.e., the side opposite to the drum opening of the first drum 400) and the bottom of the second drum 500 (i.e., the side opposite to the drum opening of the second drum 500). In particular, the air outlet duct 600 can be connected to the bottom and at least partially arranged above the first drum 400 and the second drum 500, so that water, foam, etc. in the drum is less likely to enter the air outlet duct 600. The air outlet duct 600 and the drying air inlet assembly can be staggered in the axial direction of the laundry treatment drum (the axial directions of the first drum 400 and the second drum 500 are parallel) (i.e., the air outlet duct 600 and the isolation air duct are located at different positions in the axial direction), so that the air outlet duct 600 and the drying air inlet assembly do not interfere with each other above the first drum 400 and the second drum 500, and the internal space of the multi-drum laundry treatment device can be saved.

[0109] The multi-drum laundry treatment device can further comprise more laundry treatment drums, for example, a third drum arranged above the first drum 400 and the second drum 500, and a fourth drum arranged below the first drum 400 and the second drum 500. The diameters of the third drum and the fourth drum can be greater than the diameters of the first drum 400 and the second drum 500, for example, the diameters of the third drum and the fourth drum can be about twice the diameters of the first drum 400 and the second drum 500.

[0110] It can be understood that the multi-drum laundry treatment device can uniformly deliver the drying hot air flow to two or more laundry treatment drums, but it is not mandatory that the two or more laundry treatment drums must perform drying operations at the same time, i.e., the user / program is allowed to autonomously select whether one or more laundry treatment drums perform drying operations (at the same time).

[0111] The following briefly describes some beneficial effects of the above-mentioned embodiments of the present application.

[0112] The embodiments of the present application provide a drying air inlet assembly for a multi-drum laundry treating apparatus. The internal part of the drying air interface can be provided with a flow distribution plate to separate the drying air interface into a first interface channel and a second interface channel. According to the pressure drop characteristics of different air ducts connected downstream of the drying air interface, the first interface channel and the second interface channel can be set to different sizes to achieve uniform drying air flow into the two laundry treating barrels at the same time. In turn, the at least two laundry treating barrels of the multi-drum laundry treating apparatus can simultaneously perform drying operations with good consistency of drying air flow inlet distribution. Using one drying device to simultaneously perform drying operations on multiple laundry treating barrels can save energy, reduce laundry treating operation time and improve user experience.

[0113] It can be understood that, in the present application, the number of components or members can be one or more when not particularly limited, and the plurality herein refers to two or more. For the case where the number of components or members is specifically described as, for example, two, three, four, etc. in the drawings and / or the description, the specific number is generally exemplary rather than limiting, and can be understood as a plurality, i.e. two or more, but this does not mean that the present application excludes the case of one.

[0114] It should be understood that the above embodiments are only exemplary and are not intended to limit the present application. Those skilled in the art can make various modifications and changes to the above embodiments under the teachings of the present application without departing from the scope of the present application.
