DETAILED DESCRIPTION

[0049] The following describes the implementation of the present invention using specific embodiments. Those skilled in the art will readily understand the other advantages and benefits of the present invention from the disclosure herein. Obviously, the embodiments described are only a portion of the present invention, not all of it. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are intended to fall within the scope of protection of the present invention.

[0050] The terms used in the embodiments of the present invention are for the purpose of describing specific embodiments only and are not intended to limit the present invention. The singular forms "a," "the," and "the" used in the embodiments of the present invention and the appended claims are also intended to include plural forms, unless the context clearly indicates otherwise. "A plurality" generally includes at least two, but does not exclude the inclusion of at least one.

[0051] It should be understood that the term "and / or" as used herein is merely a description of the relationship between associated objects, indicating that three possible relationships exist. For example, "A and / or B" can represent: A exists alone, A and B exist simultaneously, or B exists alone. Furthermore, the character " / " in this document generally indicates that the associated objects are in an "or" relationship.

[0052] It should also be noted that the terms "include," "comprises," or any other variations thereof are intended to encompass non-exclusive inclusion, such that a product or system comprising a series of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such product or system. In the absence of further limitations, an element defined by the phrase "comprises a..." does not exclude the presence of other identical elements in the product or system comprising the element.

[0053] In the prior art, the condensing device required for dehumidifying the drying airflow is poorly designed. This results in insufficient contact between the drying airflow and the condensed water, and a small heat exchange area, leading to low condensation efficiency and incomplete dehumidification. Furthermore, the inability to promptly remove debris from the drying airflow leads to unreliable operation of the downstream drying fan and heating equipment.

[0054] The present invention creatively provides a condensing assembly for use in a clothes processing device; the condensing assembly includes a condensing air duct and a water channel plate, and the condensing air can flow through the drying air flow; the water channel plate is arranged in the condensing air duct and forms a first water channel and a second water channel; a first water outlet is formed on the bottom wall of the first water channel, and the first water outlet is connected to the first water channel and the condensing air duct; a second water outlet is formed on the side wall of the second water channel, and the second water outlet is connected to the second water channel and the condensing air duct;

[0055] When dehumidification of the drying airflow is required, the condensed water enters the second water channel and is discharged to the condensation air duct through the second water outlet. The condensed water and the drying airflow are fully in contact and heat exchanged. This improves the condensation efficiency, dehumidifies thoroughly, shortens the drying time, and solves the problems of low condensation efficiency and incomplete dehumidification caused by insufficient contact between the drying airflow and the condensed water and the small heat exchange area.

[0056] When it is necessary to remove dander in the drying air flow, the condensed water is allowed to enter the first water channel and discharged to the condensation air duct through the first water outlet. The condensed water can absorb the dander in the drying air flow, and the dander can move downward with the condensed water and separate from the drying air flow, thereby solving the problem of incomplete removal of dander in the drying air flow, resulting in unreliable operation of the downstream drying fan and heating equipment.

[0057] Example 1

[0058] <Condensation Components>

[0059] like Figures 1a to 4c As shown, this embodiment provides a condensing assembly for a clothes processing device; the condensing assembly includes:

[0060] The condensation duct 14 can flow through the drying air flow. The drying air flow can flow through the condensation duct 14 from bottom to top. The condensation duct 14 includes a condensation air inlet and a condensation air outlet 1431 connected to the condensation duct 14. The drying air flow can enter the condensation duct 14 through the condensation air inlet and be discharged from the condensation duct 14 through the condensation air outlet 1431.

[0061] The waterway plate 2 is disposed in the condensation air duct 14 and is formed with a first water channel 21 and a second water channel 22; a first water outlet 211 is formed on the bottom wall of the first water channel 21, the first water outlet 211 connects the first water channel 21 and the condensation air duct 14, and the first water outlet 211 faces downward; condensed water can enter the first water channel 21 and be discharged downward to the condensation air duct 14 through the first water outlet 211; a second water outlet 221 is formed on the side wall of the second water channel 22, the second water outlet 221 connects the second water channel 22 and the condensation air duct 14, and the second water outlet 221 faces a side away from the side wall of the second water channel 22; condensed water can enter the second water channel 22 and be discharged forward to the condensation air duct 14 through the second water outlet 221;

[0062] The condensed water can selectively enter the first water channel 21 and be discharged to the condensation air duct 14 through the first water outlet 211, and / or enter the second water channel 22 and be discharged to the condensation air duct 14 through the second water outlet 221; by controlling the condensed water to enter the first water channel 21 and / or the second water channel 22, the flow rate and direction of the condensed water entering the condensation air duct 14 are adjusted to achieve different condensation effects and dander removal effects.

[0063] To address the problem of low condensation efficiency and low lint removal efficiency caused by unreasonable positioning of the first water channel 21 and the second water channel 22, this embodiment proposes that the first water channel 21 and the second water channel 22 are arranged in parallel with each other, with the first water channel 21 located below the second water channel 22; the lateral extension length of the first water channel 21 is greater than the lateral extension length of the second water channel 22;

[0064] Along the lateral extension direction of the first water channel 21, a plurality of first water outlets 211 are formed on the bottom wall of the first water channel 21, and the condensed water in the first water channel 21 can be discharged to the condensation air duct 14 through the plurality of first water outlets 211; along the lateral extension direction of the second water channel 22, a plurality of second water outlets 221 are formed on the side wall of the second water channel 22, and the condensed water in the second water channel 22 can be discharged to the condensation air duct 14 through the plurality of second water outlets 221.

[0065] To address the problem of complex structure of the waterway plate 2, this embodiment proposes that the waterway plate 2 further includes a third waterway 23 and a fourth waterway 24; the third waterway 23 is connected to the first waterway 21 through the communication port A 251, and the fourth waterway 24 is connected to the second waterway 22 through the communication port D 254;

[0066] The condensed water may enter the first water channel 21 through the third water channel 23 and the A communication port 251 , and / or enter the second water channel 22 through the fourth water channel 24 and the D communication port 254 .

[0067] Furthermore, the third water channel 23 is connected to the second water channel 22 through the B connecting port 252; a first retaining rib 261 is provided in the second water channel 22, and the first retaining rib 261 is close to the B connecting port 252, and a first gap 263 is formed between the first retaining rib 261 and the side wall of the second water channel 22; the flow area of ​​the first gap 263 is smaller than the flow area of ​​the A connecting port 251; a part of the condensed water entering the third water channel 23 can enter the first water channel 21 through the A connecting port 251, and another part of the condensed water entering the third water channel 23 can enter the second water channel 22 through the first gap 263.

[0068] The fourth water channel 24 is connected to the first water channel 21 through the C connecting port 253; a second rib 262 is provided in the fourth water channel 24, the second rib 262 is close to the D connecting port 254, and a second gap 264 is formed between the second rib 262 and the side wall of the fourth water channel 24; the flow area of ​​the second gap 264 is smaller than the flow area of ​​the D connecting port 254; a part of the water entering the fourth water channel 24 can enter the second water channel 22 through the D connecting port 254, and another part of the condensed water entering the fourth water channel 24 can enter the first water channel 21 through the second gap 264.

[0069] In response to the problem that the condensed water entering the fourth water channel 24 cannot smoothly enter the first water channel 21 due to the unreasonable structural design of the fourth water channel 24, this embodiment proposes that the fourth water channel 24 includes a water inlet section 241 and a connecting section 242. The water inlet section 241 is arranged parallel to the third water channel 23, one end of the connecting section 242 is connected to the D connecting port 254, and the other end of the connecting section 242 is connected to the C connecting port 253; a second retaining rib 262 is provided in the connecting section 242.

[0070] In summary, there are three ways for condensed water to enter the condensation air duct 14 through the water channel plate 2:

[0071] ① Such as Figure 4a As shown, when the drying airflow needs to be dehumidified, the condensed water enters the fourth water channel 24, of which a portion of the condensed water enters the second water channel 22 through the D connecting port 254 and enters the condensation air duct 14 in a parabolic shape through the second water outlet 221. This portion of the condensed water fully contacts and exchanges heat with the drying airflow; another portion of the condensed water enters the first water channel 21 through the second gap 264 and the C connecting port 253 and is sprayed into the condensation air duct 14 through the first water outlet 211; the condensed water flow rate entering the second water channel 22 is greater than the condensed water flow rate entering the first water channel 21, and the water channel plate 2 is mainly used for condensation dehumidification; at this time, the first air duct is in the condensation state;

[0072] ② If Figure 4bAs shown, when it is necessary to remove lint from the drying airflow, condensed water enters the third water channel 23, a portion of which enters the second water channel 22 through the first gap 263 and enters the condensation air duct 14 in a parabolic shape through the second water outlet 221, while another portion of condensed water enters the first water channel 21 through the connecting port A 251 and is sprayed downward through the first water outlet 211 into the condensation air duct 14; this portion of condensed water can absorb lint from the drying airflow; the flow rate of condensed water entering the first water channel 21 is greater than the flow rate of condensed water entering the second water channel 22, and the waterway plate 2 mainly sprays and absorbs lint; this is the second air duct condensation state;

[0073] ③ Such as Figure 4c As shown, when the drying airflow needs to be cooled, part of the condensed water enters the first water channel 21 and the second water channel 22 through the third water channel 23, and the other part of the condensed water enters the first water channel 21 and the second water channel 22 through the fourth water channel 24; the pressure inside the waterway plate 2 is the largest, and the condensed water is discharged to the condensation air channel 14 in a water curtain shape through the first water outlet 211 and in a larger parabola shape through the second water outlet 221; the temperature of the drying airflow is quickly reduced to the preset door opening temperature, the cooling time after the drying is completed is shortened, and the user experience is improved; the waterway plate 2 is mainly used for cooling, and it is in the third air channel condensation state at this time.

[0074] In addition, the condensation air duct 14 includes a condensation cover 12, on which a waterway plate 2 and an outer guide rib 121 are provided. The outer guide rib 121 is located downstream of the waterway plate 2; a plurality of outer guide ribs are provided, and the plurality of outer guide ribs 121 are spaced apart on the condensation cover 12; the condensed water entering the condensation air duct 14 through the first water outlet 211 and the second water outlet 221 can flow through the plurality of outer guide ribs 121, thereby increasing the heat exchange area between the condensed water and the drying airflow, so that the condensed water and the drying airflow can fully exchange heat, and extend the condensation. The condensed water stays in the condensation duct 14 for a long time, thereby improving the condensation efficiency, shortening the drying time, and saving condensed water. The condensation cover 12 is formed with a condensation water inlet 122, which includes a first condensation water inlet and a second condensation water inlet. The first condensation water inlet is connected to the third water channel 23, and the external condensed water can enter the third water channel 23 through the first condensation water inlet; the second condensation water inlet is connected to the fourth water channel 24, and the external condensed water can enter the fourth water channel 24 through the second condensation water inlet.

[0075] The outer guide ribs 121 can be a straight structure or an arc structure, and multiple outer guide ribs 121 are arranged at an angle relative to the horizontal plane; among two adjacent outer guide ribs 121, the water outlet end of the upstream outer guide rib 121 is close to the water inlet end of the downstream outer guide rib 121, so that the condensed water entering the condensation air duct 14 can flow through multiple outer guide ribs 121 in sequence; the flow path of the condensed water in the condensation air duct 14 is extended, the heat exchange area between the condensed water and the drying air flow is increased, and the condensation efficiency is improved.

[0076] The condensation cover 12 and the water channel plate 2 are both made of metal material to improve the condensation efficiency of the condensation assembly.

[0077] In this embodiment, the structure of the waterway plate is optimized to achieve different functions. Specifically, the waterway plate is designed to form a first waterway 21, a second waterway 22, a third waterway 23, and a fourth waterway 24. The first waterway 21 and the second waterway 22 are arranged in parallel, and the third waterway 23 and the fourth waterway 24 are connected to the first waterway 21 and the second waterway 22.

[0078] When the drying airflow needs to be dehumidified, the condensed water enters the fourth water channel 24, a portion of which enters the second water channel 22 and enters the condensation air duct 14 through the second water outlet 221. This portion of condensed water fully contacts and exchanges heat with the drying airflow; the other portion of condensed water enters the first water channel 21 and is sprayed into the condensation air duct 14 through the first water outlet 211. This solves the problems of insufficient contact between the drying airflow and the condensed water and the small heat exchange area, which lead to low condensation efficiency and incomplete dehumidification. It also solves the problem of unreliable operation of the downstream drying fan and heating equipment due to excessive humidity in the drying airflow.

[0079] When it is necessary to remove lint from the drying airflow, the condensed water enters the third water channel 23. A portion of the condensed water enters the second water channel 22 and enters the condensation air duct 14 through the second water outlet 221, while another portion of the condensed water enters the first water channel 21 and enters the condensation air duct 14 through the first water outlet 211. This portion of condensed water can absorb lint from the drying airflow, thus resolving the problem of unreliable operation of the downstream drying fan and heating equipment due to incomplete lint removal from the drying airflow.

[0080] When the drying airflow needs to be cooled, part of the condensed water enters the first water channel 21 and the second water channel 22 through the third water channel 23, and the other part of the condensed water enters the first water channel 21 and the second water channel 22 through the fourth water channel 24; the pressure inside the waterway plate 2 is the largest, so that the temperature of the drying airflow is quickly reduced to the preset door opening temperature, solving the problems of unreasonable structural design of the waterway plate and inappropriate flow rate and flow state of the condensed water, which lead to insufficient contact between the condensed water and the drying airflow and slow cooling speed.

[0093] <Control Method>

[0094] This embodiment further provides a control method for a clothes processing device, wherein the clothes processing device is any of the clothes processing devices described above, and the clothes processing device is provided with a drying process; the drying process includes a drying stage, and when the clothes processing device is running in the drying stage, the control method includes:

[0095] Control the condensed water to alternately enter the first water channel 21 and the second water channel 22;

[0096] The period of condensed water alternately entering the first water channel 21 and the second water channel 22 is T=t1+t2, and t2>t1; wherein t1 is the duration of condensed water entering the first water channel 21 and being discharged to the condensation air duct 14 through the first water outlet 211; t2 is the duration of condensed water entering the second water channel 22 and being discharged to the condensation air duct 14 through the second water outlet 221.

[0097] Furthermore, controlling the condensed water to alternately enter the first water channel 21 and the second water channel 22 includes:

[0098] S1, controlling the condensed water to enter the second water channel 22 and be discharged to the condensation air duct 14 through the second water outlet 221, so that the condensed water dehumidifies the drying air flow;

[0099] S2. When the condensed water is discharged to the condensation air duct 14 through the second water outlet 221 for a period of time t2, the condensed water is controlled to enter the first water channel 21 and be discharged to the condensation air duct 14 through the first water outlet 211, so that the condensed water absorbs the hair debris in the drying air flow;

[0100] S3 . When the condensed water is discharged to the condensation air duct 14 through the first water outlet 211 for a duration of t1 , the condensed water is controlled to enter the second water channel 22 and be discharged to the condensation air duct 14 through the second water outlet 221 .

[0101] In addition, the condensed water is controlled to alternately enter the first water channel 21 and the second water channel 22. At the same time, the condensed water is controlled to pass through the condensation zone, so that the drying air flow flowing through the inner side of the outer cylinder rear wall 32 exchanges heat with the condensed water flowing through the condensation zone.

[0102] In order to prevent the temperature of the drying airflow in the inner drum from being reduced in time, this embodiment proposes that the drying process includes a cooling phase. When the clothing processing device is in the cooling phase, the heating device stops moving and the drying fan 37 keeps running. The control method further includes:

[0103] Control the condensed water to enter the first water channel 21 and the second water channel 22 at the same time;

[0104] Furthermore, controlling the condensed water to enter the first water channel 21 and the second water channel 22 simultaneously includes:

[0105] Control the condensed water to enter the first water channel 21 and be discharged to the condensation air duct 14 through the first water outlet 211; control the condensed water to enter the second water channel 22 and be discharged to the condensation air duct 14 through the second water outlet 221, so that the condensed water quickly cools the drying airflow in the outer cylinder 3;

[0106] When the current temperature reaches the door opening temperature, the drying fan 37 and the heating device are stopped.

[0107] The drying process also includes a heating stage. The method for determining whether the clothing processing device enters the drying stage from the heating stage includes:

[0108] Determine whether the current temperature of the drying airflow in the outer drum 3 is greater than a preset temperature;

[0109] When the current temperature is greater than the preset temperature, it indicates that the clothes processing device has entered the drying stage from the heating stage.

[0110] In this embodiment, according to the needs of dehumidification, dander removal and cooling of the drying air flow, the condensed water is controlled to flow through the corresponding water channel; specifically, the condensed water enters the second water channel 22 and is discharged to the condensation air duct 14 through the second water outlet 221, so that the condensed water dehumidifies the drying air flow; the condensed water enters the first water channel 21 and is discharged to the condensation air duct 14 through the first water outlet 211, so that the condensed water adsorbs dander in the drying air flow; the condensed water enters the first water channel 21 and is discharged to the condensation air duct 14 through the first water outlet 211 and the condensed water enters the second water channel 22 and is discharged to the condensation air duct 14 through the second water outlet 221, so that the condensed water quickly cools the drying air flow in the outer cylinder 3; solves the problem that the unreasonable control method of the water channel plate cannot meet different needs.

[0111] Example 2

[0112] On the basis of Example 1, a third water outlet is further formed on the side wall of the first water channel 21, the third water outlet connects the first water channel 21 and the condensation air duct 14 and faces a side of the side wall away from the first water channel 21;

[0113] The condensed water can enter the first water channel 21 and be discharged to the condensation air duct 14 through the first water outlet 211 and the third water outlet;

[0114] The condensed water flow rate discharged from the first water channel 21 to the condensing air channel 14 is increased, so that more condensed water and the drying air flow come into contact and exchange heat, thereby improving the drying efficiency and solving the problem of low drying efficiency caused by insufficient condensed water flow rate.

[0115] Example 3

[0116] like Figure 6 As shown, different from embodiment 1, the control method of the clothes processing device includes:

[0117] After the clothes processing device runs the drying process, the drying fan 37 starts to run, driving the drying air flow in the outer drum 3 and the inner drum, and the heating device heats the drying air flow; specifically, the heating device is an electric heating element;

[0118] Determine whether T0 is greater than or equal to T1;

[0119] When T0 is less than T1, the current state is maintained; when T0 is greater than or equal to T1, the rear drum condensation and the first air duct condensation states are turned on to condense the hot and humid drying airflow;

[0120] After running for t1 time, the second air duct condensation state is turned on, and spraying is performed in the condensation air duct 14 to absorb the lint and dust in the drying air flow;

[0121] After running for t2 time, the first air duct condensation state is turned on again to continue condensation; in this way, the first air duct condensation state and the second alternating condensation state are turned on alternately;

[0122] The drying air flow in the inner drum is judged to be dry. When the dryness is confirmed and the temperature of the drying air flow in the inner drum is too high, the third air duct condensation state is opened; at this time, the drying fan 37 continues to operate, the heating device stops operating, and the condensed water in the condensation air duct 14 quickly cools the drying air flow in the inner drum;

[0123] Determine whether T0 is less than or equal to T2;

[0124] When T0 is greater than T1, the current state is maintained; when T0 is less than or equal to T2, the drying fan 37 and the air duct condensation stop running, and the drying ends;

[0125] Among them, T1 is the temperature at which the temperature rises to the end, T2 is the door opening temperature; t1 is the duration of the condensation state in the first air duct, and t2 is the duration of the condensation state in the second air duct;

[0126] In this embodiment, according to the needs of dehumidification, lint removal and cooling of the drying air flow, the rear drum condensation, the first air duct condensation state or the second air duct condensation state is turned on; specifically, the rear drum condensation and the first air duct condensation states are turned on to condense the hot and humid drying air flow; the second air duct condensation state is turned on, and spraying is carried out in the condensation air duct 14 to absorb the lint and dust in the drying air flow; the third air duct condensation state is turned on, and the condensed water in the condensation air duct 14 quickly cools the drying air flow in the inner drum; this solves the problem that the unreasonable control method of the water channel plate cannot meet different needs.
