[0052] In the description of the present application, it should be noted that the directions or position relationships indicated by the terms “inner”, “outer” and the like are based on the directions or position relationships shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the present application.

For those skilled in the art, the specific meanings of the above terms in the present application can be understood according to the specific circumstances.

[0054] At present, for the double-barrel washing machine with care function, when the double barrels are running at the same time, because the upper and lower barrels have different capacities, the washing, drying and care are often not completed at the same time. When the upper barrel drying ends and starts care, the lower barrel may not have completed drying. The existing double-barrel washing machine care device structure adopts a steam care device connected with an air duct, and the double barrels share one air duct. Therefore, when one barrel ends drying, care cannot be immediately performed, and care can only be performed when both barrels end drying at the same time, the care time is long, and the user experience is poor. In the embodiment of the present application, a wind distribution device is provided, which is in communication with the main drying air duct of the double-barrel washing machine. By controlling the rotation angle of the wind distribution part in the wind distribution device, different air outlets are closed to control the drying process. At the same time, a gas generating device is arranged in the wind distribution device, which can make the double-barrel washing machine achieve the following effects: when the drying air flows out of one air outlet, the gas generated in the wind distribution device can flow into the other air outlet, thereby realizing the effect of drying one barrel and caring for the other barrel.

[0055] In order to further illustrate the technical solutions in the present application, specific embodiments are provided as shown in the accompanying drawings. Figures 1-10

[0056] Embodiment 1

[0057] As shown in the accompanying drawings, Figures 1-10 In the embodiment of the present application, a wind distribution device is provided, which is applied to a double-barrel washing machine, and the double-barrel washing machine shares the same drying system. The wind distribution device comprises:

[0058] The wind distribution shell 1 has a cylindrical wind distribution cavity 11 formed in the inside, a first air outlet 13 and a second air outlet 14 formed on the surface and communicated with the wind distribution cavity 11, and an air inlet 12;

[0059] ​The air distribution member 2 is rotatably arranged in the air distribution cavity 11, and the axis of the air distribution member 2 is collinear with the axis of the air distribution cavity 11, the inside of the air distribution member 2 is formed with a water storage cavity 20, the outer circumferential surface of the air distribution member 2 comprises a first abutting surface 21 and a second abutting surface 22 which are arranged in abutment with the cavity wall surface of the air distribution cavity 11, and a first connecting surface 23 which is arranged in spacing with the cavity wall surface of the air distribution cavity 11 and is between the first abutting surface 21 and the second abutting surface 22, and a plurality of exhaust holes 231 are arranged on the first connecting surface 23 and are in communication with the water storage cavity 20;

[0060] The gas generating device 3 is connected with the air distribution member 2 and is used for generating gas in the water storage cavity 20, and preferably, the gas generating device 3 is a steam generating device which can generate steam in the water storage cavity 20;

[0061] The air distribution member 2 is designed to be capable of closing one of the first air outlet 13 and the second air outlet 14 and opening the other one when the air distribution member 2 is driven to rotate, and the exhaust holes 231 on the air distribution member 2 are in communication with the air outlet which is closed by the air distribution member 2 when the air distribution member 2 closes one of the first air outlet 13 and the second air outlet 14.

[0062] When the air distribution device in the embodiment of the present application is connected with the main drying air duct in the double-cylinder washing machine, the drying air flow in the main drying air duct can enter into the air distribution cavity 11 through the air inlet 12 of the air distribution device.

[0063] Specifically, as shown in Figure 7 When the exhaust holes 231 on the air distribution member 2 correspond to the second air outlet 14 due to the rotation of the air distribution member 2, the first abutting surface 21 and the second abutting surface 22 on the air distribution member 2 can abut with the cavity wall surface of the air distribution cavity 11 on both sides of the second air outlet 14, at this time, the drying air flow cannot be discharged through the second air outlet 14, and since the first air outlet 13 is not blocked by the air distribution member 2, the air flow entering into the air distribution cavity 11 can be discharged through the first air outlet 13, at the same time, the water storage cavity 20 in the air distribution member 2 can be filled with water, the gas generating device 3 can generate steam in the water storage cavity 20, and the generated steam can be discharged from the second air outlet 14 through the exhaust holes 231, since the first air outlet 13 and the second air outlet 14 are respectively connected with different laundry treatment cylinders, the drying air flow can be discharged into one of the laundry treatment cylinders to dry the laundry, and the care steam can be discharged into the other laundry treatment cylinder to care the laundry.

[0064] More specifically, as shown in Figure 8As shown, when the exhaust hole 231 on the air distribution piece 2 corresponds to the first air outlet 13 due to the rotation of the air distribution piece 2, the first fitting surface 21 and the second fitting surface 22 on the air distribution piece 2 can be fitted with the cavity wall surface of the air distribution cavity 11 on both sides of the first air outlet 13, at this time, the drying airflow cannot be discharged through the first air outlet 13, and since the second air outlet 14 is not blocked by the air distribution piece 2, the drying airflow entering the air distribution cavity 11 can be discharged through the second air outlet 14, and the water storage cavity 20 inside the air distribution piece 2 can be filled with water. The gas generating device 3 can generate steam from the water in the water storage cavity 20, and the generated steam can be discharged from the first air outlet 13 through the exhaust hole 231. Since the first air outlet 13 and the second air outlet 14 are respectively connected to different clothes treatment barrels, the drying airflow can be discharged into one of the clothes treatment barrels to dry the clothes, and the care steam can be discharged into the other clothes treatment barrel to care for the clothes.

[0065] That is, in the embodiment of the present application, by rotating the angle of the air distribution piece 2, the drying airflow entering the air distribution cavity 11 can be kept in communication with only one of the air outlets, and the exhaust hole 231 on the air distribution piece 2 is kept in communication with the other air outlet, so that the effect of drying one clothes treatment barrel and caring for the other clothes treatment barrel can be achieved.

[0066] Of course, as shown in the drawings, Figure 9 In the embodiment of the present application, by controlling the rotation angle of the air distribution piece 2, the first air outlet 13 and the second air outlet 13 can also be kept in communication with the drying airflow in the air distribution cavity 11, so that the drying airflow entering the air distribution cavity 11 can simultaneously dry the clothes in the two clothes treatment barrels.

[0067] Preferably, as shown in the drawings, Figures 7-9 The cavity wall surface of the air distribution cavity 21 forms a first arc-shaped region at the first air outlet 13, a second arc-shaped region at the second air outlet 14, a third arc-shaped region and a fourth arc-shaped region between the first air outlet 13 and the second air outlet 14, and the air inlet 12 is formed at the three arc-shaped regions or the fourth arc-shaped region, the arc length of the first arc-shaped region is L1, the arc length of the second arc-shaped region is L2, the arc length of the third arc-shaped region is L3, and the arc length of the fourth arc-shaped region is L4;

[0068] A fifth arc-shaped region is formed between the first fitting surface 21 and the second fitting surface 22 of the air distribution piece 2, and the arc length of the fifth arc-shaped region is L5;

[0069] L1, L2, L3, L4 and L5 satisfy: L5>L1, L5>L2, L5>L3, L5<L1+L2+L3, and L5<L1+L2+L4.

[0070] In the embodiment of the present application, the size of the air distributing piece and the air outlet (the first air outlet 13 and the second air outlet 14) is set, so that the air distributing piece 2 can make the first air outlet 13 and the air inlet 12 communicate alone, make the second air outlet 14 and the air inlet 12 communicate alone, and make the first air outlet 13 and the second air outlet 14 and the air inlet 12 communicate simultaneously when rotating, so that the two clothes treatment drums can simultaneously perform drying operation, and one of the two clothes treatment drums can perform drying operation and the other can perform steam care operation. Thus, the problem that care cannot be performed immediately when one of the two clothes treatment drums ends drying, and care can be performed only when both of the two clothes treatment drums end drying is avoided.

[0071] In any of the above embodiments, as shown in Figure 6 The outer circumferential surface of the air distributing piece 2 further comprises a second connecting surface 24 arranged opposite to the first connecting surface 23 between the first and second adhering surfaces 21 and 22, and the first and second adhering surfaces 21 and 22, the first and second connecting surfaces 23 and 24 enclose the air distributing piece 2 with the water storage cavity 20 inside;

[0072] At least part of the gas generating device 3 is mounted on the first connecting surface 23.

[0073] As shown in Figures 7-9 In the embodiment of the present application, at least part of the gas generating device 3 is mounted on the first connecting surface 23, so as to prevent the high-temperature gas flow entering the air distributing cavity 11 from the air inlet 12 from directly contacting the gas generating device 3, thereby avoiding damage to the gas generating device 3.

[0074] Specifically, as shown in Figure 6 The gas generating device 3 comprises a connecting part 31 and a gas generating part 32.

[0075] The connecting part 31 is mounted on the first connecting surface 23 of the air distributing piece 2, and the gas generating part 32 is mounted in the water storage cavity 20 of the air distributing piece 2.

[0076] In the embodiment of the present application, the connecting part 31 of the gas generating device 3 is arranged outside the water storage cavity 20, so as to prevent the gas generating device 3 from being completely placed in water and being damaged. Therefore, in the embodiment, only the gas generating part 32 having the gas generating function is arranged in the water storage cavity 20.

[0077] Further, as shown in Figure 6 In order to facilitate mounting of the connecting part of the gas generating device 3 on the first connecting surface 23, the air distributing piece 2 in the embodiment forms a cavity 25 on one side of the first connecting surface 21, and the connecting part 31 is accommodated in the cavity 25.

[0078] In any of the above embodiments, as shown in Figures 4-6 The rotating shaft 4 is fixedly connected to the air distributing member 2 at the axial position of the air distributing member 2, and is at least partially arranged in the water storage cavity 20 of the air distributing member 2. The rotating shaft 4 is connected to a stepping motor, which drives the rotating shaft 4 to rotate, thereby driving the air distributing member 2 to rotate.

[0079] The rotating shaft 4 is a hollow rotating shaft body having a water inlet and a water outlet. The water inlet is arranged outside the water storage cavity 20 of the air distributing member 2, and the water outlet is arranged in the water storage cavity 20 of the air distributing member 2.

[0080] In this way, the rotating shaft 4 can drive the air distributing member 2 to rotate, and at the same time, water can be discharged into the water storage cavity 20 of the air distributing member 2.

[0081] Further, the water outlet of the rotating shaft 4 is arranged to face the gas generating device 3.

[0082] In this way, the water discharged through the water outlet of the rotating shaft 4 can directly contact the gas generating device 3, so that the steam can act on the clothes in the clothes treatment drum in the first time.

[0083] In any of the above embodiments, as shown in Figures 7-9 The water storage cavity 20 includes a first chamber 201 and a second chamber 202. The water outlet of the rotating shaft 4 is in communication with the first chamber 201. The gas generating device 3 is used to generate gas from the water in the first chamber 201. The exhaust hole 231 is in communication with the second chamber 202.

[0084] A switchable component (not shown in the figure) is arranged between the first chamber 201 and the second chamber 202. The switchable component is used to open or close the first chamber 201 and the second chamber 202.

[0085] In the embodiment of the present application, by arranging the switchable component between the first chamber 201 and the second chamber 202, the water discharged into the water storage cavity 20 can be prevented from being directly discharged through the exhaust hole 231 without being evaporated, thereby improving the steam care effect on the clothes.

[0086] Further, the air distributing device further comprises:

[0087] A temperature sensor is connected to the air distributing member 2, and is used to monitor the temperature in the first chamber 201.

[0088] When the temperature in the first chamber 201 reaches a preset threshold value, the switchable component is controlled to be opened to open the first chamber 201 and the second chamber 202. When the temperature in the first chamber 201 does not reach the preset threshold value, the switchable component is controlled to be closed to close the first chamber 201 and the second chamber 202.
