[0054] Existing clothing processing devices cannot change the inlet angle of the drying air entering the inner drum during the drying process, nor can they adjust the outlet angle to meet different needs, making the drying function too mechanical and sometimes damaging the clothes. In embodiments of the present invention, an air guide assembly is provided at the outlet of the outer circulation drying air duct of the clothing processing device. This allows the drying air entering the inner drum to be guided according to the actual drying conditions, thereby improving the drying effect of the clothes.

[0055] The following is combined with Figures 1-8 The technical solution of this embodiment is described in detail. The following implementation methods and embodiments can be combined with each other unless there is any conflict.

[0056] Example

[0057] like Figure 1-Figure 5 As shown, this embodiment provides a clothes processing device, including:

[0058] The laundry treatment drum comprises an outer drum 1 and an inner drum (not shown in the figure) pivotally arranged in the outer drum;

[0059] The air inlet of the external circulation drying air duct is connected to the outer cylinder 1, and the air outlet is connected to the inner cylinder;

[0060] The air guide component is connected to the air outlet 2 of the external circulation drying air duct and is used to adjust the air outlet direction of the air outlet 2 when the air outlet 2 is discharging air.

[0061] In the embodiment of the present invention, an air guide component is provided at the air outlet 2 of the external circulation drying duct of the clothing processing equipment. When drying clothes, the drying air entering the inner drum can be guided according to the actual drying conditions to improve the drying effect of the clothes.

[0062] Specifically, the clothing processing device further includes:

[0063] A detection module is used to detect clothing information in the inner drum;

[0064] A control module, which is used to adjust the air outlet direction of the air outlet 2 according to clothing information;

[0065] The clothing information includes the material of the clothing and / or the weight of the clothing.

[0066] That is, when drying clothes, the clothing processing device in the embodiment of the present invention can adjust the direction of the drying air entering the inner drum according to the material and / or weight of the clothes, thereby achieving a variable air intake effect and changing the care and drying rate according to different amounts of clothes and materials.

[0067] In any of the above embodiments, Figure 2 As shown, the air guide assembly includes an air guide plate 3 provided at the air outlet 2 of the external circulation drying duct and a rotating screw mechanism connected to the air guide plate 3, wherein the rotating screw mechanism is provided inside the air outlet 2 (not shown in the drawings);

[0068] The rotating screw mechanism can drive the air guide plate 3 to rotate to change the air outlet direction of the air outlet 2.

[0069] It should be noted that, in the embodiment of the present invention, a plurality of air guide plates 3 are provided, and the plurality of air guide plates 3 can be driven to rotate synchronously by the rotating screw mechanism.

[0070] It should also be noted that the above-mentioned rotating screw mechanism and air guide plate have similar functions to the rotating screw mechanism and air guide plate in other air outlet equipment (such as air conditioners). Although the specific structure of the rotating screw mechanism and the air guide plate is not described in the embodiment of the present invention, people in this field are aware of how to adjust the wind direction by this means.

[0071] In any of the above embodiments, the air outlet 2 plane of the external circulation drying duct is parallel to the horizontal plane where the inner drum rotation axis is located, and in the height direction of the inner drum, the air outlet plane of the external circulation drying duct is higher than the horizontal plane where the inner drum rotation axis is located.

[0072] That is, in the embodiment of the present invention, the air outlet 2 is arranged above the rotation axis of the inner drum, so that when the air outlet 2 discharges air toward the clothes, it can maximize the coverage of the clothes in the inner drum, thereby improving the drying effect of the clothes in the inner drum.

[0073] In any of the above embodiments, a rear cylinder condensation duct is formed between the rear portion of the outer cylinder 1 and the rear portion of the inner cylinder, and guide ribs are provided on the inner wall of the rear portion of the outer cylinder 1 to guide condensed water flowing into the rear cylinder condensation duct;

[0074] The air inlet of the external circulation drying air duct is connected to the rear drum condensing air duct.

[0075] That is, the clothes processing apparatus in the embodiment of the present invention has a dual condensation function (condensation in the rear drum condensation duct and condensation in the external circulation drying duct), thereby improving the condensation effect of the clothes processing apparatus.

[0076] In any of the above embodiments, Figure 1 As shown, the clothes processing device further includes a fan 4, which includes a first air inlet and a fan outlet and an air duct cavity between the first air inlet and the fan outlet;

[0077] The external circulation drying air duct includes a condensing air duct 5 and a heating air duct 6. The air inlet of the condensing air duct 5 is connected to the outer cylinder 1, the air outlet of the condensing air duct 5 is connected to the first air inlet of the fan 4, the air outlet of the fan is connected to the air inlet of the heating air duct 6, and the air outlet of the heating air duct 6 is connected to the inner cylinder;

[0078] The fan 4 further includes a second air inlet 41, one end of which is connected to the external environment of the clothes processing drum, and the other end is connected to the air duct cavity of the fan 4;

[0079] The fan 4 is a variable frequency fan, that is, the fan 4 in the embodiment of the present invention is a double-suction fan (with two air suction ports) with a variable frequency function.

[0080] That is, the clothing processing device in the embodiment of the present invention, on the basis of double condensation, is equipped with a double suction fan with two air inlets to introduce fresh air. At the same time, a rotatable air guide plate is added at the air outlet 2 of the external circulation drying duct, and the air inlet angle and wind speed are adjusted by rotation. At the same time, the speed of the fan 4 is adjusted to achieve a variable air intake effect, and the care and drying rate are changed according to different amounts of clothes and materials.

[0081] Specifically, such as Figure 3 As shown, the fan 4 further includes a fan blade 42 disposed in the air duct cavity, the fan blade 42 includes a first fan blade 421 and a second fan blade 422 disposed coaxially, wherein the second fan blade 422 is disposed relative to the first fan blade 421 and close to the second air inlet 41;

[0082] When the first fan blade 421 and the second fan blade 422 are driven to rotate, the first fan blade 421 is used to circulate the air flow in the external circulation drying duct, and the second fan blade 422 is used to introduce fresh air from outside the clothing processing equipment into the external circulation drying duct when the air flow in the external circulation drying duct circulates.

[0083] More specifically, Figure 3 As shown, the fan blade 41 further includes a partition structure 423 provided between the first fan blade 421 and the second fan blade 422 . The partition structure 423 is used to open or close the second air inlet 41 .

[0084] In the embodiment of the present invention, the second air inlet 41 (i.e., the fresh air inlet) can be opened or closed by arranging the first fan blade 421 and the second fan blade 422. Therefore, the second air inlet 41 can be opened when the clothing processing device needs fresh air, and can be closed when the clothing processing device does not need to introduce fresh air, thereby avoiding unnecessary fresh air being introduced into the inner drum and affecting the drying effect of the clothes.

[0085] In any of the above embodiments, the laundry processing device further includes:

[0086] A box body (not shown in the figure), in which the clothes processing drum is arranged;

[0087] Humidity sensor, the humidity sensor is used to detect the relative humidity of the environment between the box and the clothes processing drum;

[0088] The control module is used to control the opening and closing of the second air inlet 41 according to the relative humidity of the environment.

[0089] Specifically, when the system detects that the cooling process is in progress, the relative humidity d1 of the environment between the detection box and the clothes processing drum is turned on. If d1 is less than 85% of the target humidity, the second air inlet 41 of the fan 4 is turned on to start introducing fresh air; on the contrary, if d1 is greater than or equal to 85% of the target humidity, the second air inlet 41 of the fan 4 is closed, and the system is only an internal circulation, and the fan 4 does not introduce fresh air to prevent the environment humidity from being too high, thereby producing the opposite effect.

[0090] Specifically, the control module is used to control the air outlet control device to open or close the second air inlet 41 according to the relative humidity of the environment.

[0091] More specifically, Figure 4 and Figure 5 As shown, the air outlet control device includes a plurality of window blades 7 arranged around the center of the second air inlet 41, and the plurality of window blades 7 can be controlled to rotate synchronously;

[0092] When multiple window blades 7 are controlled to rotate synchronously, they can open or close the second air inlet 41. When multiple window blades 7 open the second air inlet 41, an air flow channel connected to the second air inlet 41 can be defined between two adjacent window blades 7, and the cross-sectional area and air inlet direction of the air flow channel can change with the rotation angle of the window blades 7.

[0093] In the embodiment of the present invention, the air intake angle of the air flow channel formed between two adjacent window blades 7 is inclined to the second air inlet 41. When the air flow enters the second air inlet 41 from the air flow channel, the fresh air can be mixed with the circulating air flow in the clothing treatment drum in the form of turbulence, thereby improving the mixing effect of the two air flows with different temperatures (the air flow temperature in the clothing treatment drum is higher, and the fresh air temperature is lower), thereby avoiding the uneven mixing of the two air flows affecting the service life of the heating device (if the two air flows with different temperatures are not mixed evenly, then the mixed air flow of one cold and one hot will affect the service life of the heating device when passing through the heating device).

[0094] In any of the above embodiments, the window blade 7 includes a head portion and a tail portion, wherein when the plurality of window blades 7 are controlled to rotate synchronously, the plurality of window blades 7 can be sequentially engaged head to tail in the circumferential direction of the second air inlet 41 to close the second air inlet 41, that is, Figure 4 shown.

[0095] In any of the above embodiments, the window blade 7 includes a first blade surface and a second blade surface formed opposite to each other;

[0096] When an air flow channel is defined between two adjacent window blades 7 , the first blade surface of one window blade 7 and the second blade surface of the other window blade 7 serve as channel surfaces of the air flow channel.

[0097] In the embodiment of the present invention, the blade surfaces of two adjacent window blades 7 are used as the channel surfaces of the air flow channel. On the one hand, the cross-sectional area of ​​the air flow channel and the amount of fresh air intake can be changed by rotating the window blades 7. On the other hand, the air intake direction of the air flow channel can be changed by rotating the window blades 7. On the other hand, by using the blade surfaces of the window blades 7 as the channel surfaces, it can be avoided that the air flow generates large noise when passing through the window blades 7.

[0098] In any of the above embodiments, Figure 4 and Figure 5 As shown, the fan further includes a wind cover 9 arranged around the outer periphery of the second air suction port, and the air port control device further includes a driving portion 8 arranged at the center of the second air inlet 41, wherein the second air inlet 41 is formed between the wind cover 9 and the driving portion 8;

[0099] The window blade 7 includes a blade shaft 71 and a blade 72. One end of the blade shaft 71 is rotatably mounted on the outer periphery of the driving portion 8, and the other end extends to the upper end surface of the wind shield 9. The driving portion 8 can drive the blade 71 to rotate. The blade 721 is fixed to the outer periphery of the blade shaft 71.

[0100] The multiple blade shafts 71 can be controlled to rotate synchronously to drive the multiple blades 72 to rotate synchronously. When the multiple blades 72 rotate synchronously, an air flow channel communicating with the second air inlet 41 can be defined between two adjacent blades 72. When the rotation angle of the blades 72 changes, the cross-sectional area of ​​the air flow channel and the air inlet direction can change. Figure 5 As shown;

[0101] In the embodiment of the present invention, by using the blade shaft 71 as a driving shaft, it is convenient to connect the plurality of window blades 7 to the driving structure, so that the plurality of window blades 7 can be driven to rotate synchronously by one driving mechanism.

[0102] Specifically, the driving part 8 can be a gear meshing transmission structure or a chain transmission mechanism, but is not limited to the above transmission mechanisms. As long as it can drive multiple window blades 7 to rotate simultaneously, the specific structure of the transmission mechanism will not be described in detail in the embodiment of the present invention.

[0103] In order to more clearly understand the working principle of the clothes processing device in the embodiment of the present invention, Figure 1-Figure 3 To explain in detail:

[0104] When the clothes processing equipment enters the drying program, part of the hot and humid air in the inner drum is directly condensed in the condensation duct 5, and part of it is condensed on the inner surface of the outer drum and then enters the condensation duct 5. The fan 4 drives this part of the dehumidified air and the introduced fresh air, which is heated by the heating duct 6 and then sent into the inner drum through the air outlet 2 to continue drying the clothes, completing the cycle.

[0105] The hot and humid air and fresh air are driven into the heating air duct 6 mainly by the fan blade structure in the embodiment of the present invention, such as Figure 3 As shown, compared with the traditional fan blade structure, the fan blade 42 in the embodiment of the present invention adds a second fan blade 422 on the basis of the original first fan blade 421. The first fan blade 421 and the second fan blade 422 are separated by a partition structure. The fresh air enters from the upper oblique direction of the fan volute, passes through the second fan blade 422, and is heated and circulated with the dehumidified low-temperature air after passing through the first fan blade 421.

[0106] Further, such as Figure 2 As shown, in the embodiment of the present invention, an air guide plate 3 and a rotatable screw mechanism are provided at the air outlet 2 of the external circulation drying air duct. The screw is driven to rotate by a stepping motor, thereby driving the air guide plate to rotate to different angles, so that the air flow is blown into the barrel at different angles.

[0107] For example, when there is less laundry in the inner drum, the angle of the air guide plate 3 can be adjusted to the bottom of the inner drum to accurately deliver air to the least amount of laundry, thereby improving drying efficiency.

[0108] For another example, when the clothes are made of silk or wool, the angle of the air guide plate 3 can be changed during drying so that the air supply direction changes and swings back and forth, reducing damage to clothes made of this material.

[0109] Therefore, in the embodiment of the present invention, by providing an air guide component at the air outlet 2 of the external circulation drying air duct, the effect of specializing in drying and protecting clothes can be achieved to a certain extent.

[0110] The second aspect of the embodiment of the present invention further provides a Figure 6-Figure 8 The drying control method of the clothes processing device shown is applied to the above clothes processing device, wherein the control method includes:

[0111] In the drying program, the information of the clothes in the inner drum is obtained, and the air outlet direction of the external circulation drying duct outlet is controlled according to the clothing information.

[0112] When the air outlet 2 in the embodiment of the present invention is discharging air, its air outlet direction can be changed according to the information of the clothes in the inner drum, so as to achieve the effect of special drying and special protection of clothes when drying the clothes.

[0113] Specifically, the method for controlling the air outlet direction of the external circulation drying duct according to the clothing information includes:

[0114] The air outlet direction of the outer circulation drying air duct outlet is controlled according to the material of the clothes and / or the air outlet direction of the outer circulation drying air duct outlet is controlled according to the weight of the clothes.

[0115] Further, such as Figure 5 As shown, the method of controlling the air outlet direction of the external circulation drying duct outlet according to the material of the clothes and / or controlling the air outlet direction of the external circulation drying duct outlet according to the weight of the clothes includes:

[0116] Determine whether the material of the clothing is precious fabric;

[0117] If the clothes are made of precious fabrics, the air outlet of the external circulation drying duct is controlled to swing up and down within the preset angle range;

[0118] If the clothes are not made of precious fabrics, the air outlet direction of the external circulation drying duct will be controlled according to the weight of the clothes;

[0119] Precious fabrics include silk, wool, down, etc.

[0120] Specifically, the drying control method of the embodiment of the present invention prioritizes obtaining information about the material of the clothing when drying it. If the clothing is made of a precious material, the air outlet of the external circulation drying duct is controlled to swing upward and downward within a preset angle range to prevent damage to the precious clothing caused by continuous dry air flow. If the clothing is not made of a precious material, the weight of the clothing is further determined, and the air outlet direction of air outlet 2 is adjusted accordingly.

[0121] Of course, in some alternative implementations, the weight of the clothes may be obtained separately to control the air outlet direction of the air outlet 2 .

[0122] Specifically, such as Figure 6 As shown, the method for controlling the air outlet direction of the external circulation drying duct according to the weight of the clothes includes:

[0123] When the weight of the clothes in the inner drum is greater than the preset weight value, the air outlet of the outer circulation drying duct is controlled to discharge air in a first direction, wherein the first angle a formed between the first direction and the plane of the air outlet is less than 90°; Figure 6 As shown;

[0124] When the weight of the clothes in the inner drum is less than the preset weight value, the air outlet of the outer circulation drying duct is controlled to discharge air in the second direction, wherein the second direction forms a second angle b greater than 90° with the plane of the air outlet, such as Figure 7 shown.

[0125] Other embodiments of the present invention will readily occur to those skilled in the art after considering the specification and practicing the embodiments disclosed herein. This application is intended to cover any variations, uses, or adaptations of the present invention that follow from the general principles of the invention and include common knowledge or customary techniques in the art not disclosed herein. The specification and examples are to be considered as exemplary only, with the true scope and spirit of the invention being indicated by the following claims.
