[0068] <Drying system>

[0069] like Figure 1 As shown, this embodiment provides a drying system for a clothes processing device, which includes an outer drum 11, a wall of the outer drum 11 is formed with a drying air outlet 111, a tube opening of the outer drum 11 is formed with a drying air inlet 112, and an inner drum 12 is rotatably arranged in the outer drum 11; specifically, a door seal is provided at the tube opening of the outer drum 11, and the door seal is formed with a drying air inlet 112;

[0070] The drying system includes a drying duct connected between the drying air inlet 112 and the drying air outlet 111. The drying duct, the outer drum 11 and the inner drum 12 form a drying air flow circuit. The drying duct includes:

[0071] Heating air duct section 21 and condensing air duct section 22,

[0072] The chip removal air duct section 3 and the transition air duct section 4 are connected in parallel between the heating air duct section 21 and the condensing air duct section 22; the chip removal air duct section 3 is provided with a cyclone separator for separating the drying air flow and the hair chips;

[0073] Specifically, the heating air duct section 21 is arranged near the drying air inlet 112, and a heating element 23 is provided in the heating air duct section 21 to heat the drying air flow; the condensing air duct section 22 is arranged near the drying air outlet 111, and a condenser is provided in the condensing air duct section 22 or condensed water can flow through the condensing air duct section 22 to dehumidify the drying air flow; the drying air flow flowing out of the drying air outlet 111 first flows through the condensing air duct section 22 for cooling and then flows into the heating air duct section 21 for heating; a drying fan 24 is also provided at one end of the heating air duct section 21 near the condensing air duct section 22, and the drying fan 24 provides power for the drying air flow to circulate in the drying air flow loop;

[0074] When the drying air flow contains a large amount of hair debris, the chip removal air duct section 3 is connected to the condensing air duct section 22 and the heating air duct section 21, and the drying air flow in the condensing air duct section 22 can enter the heating air duct section 21 through the chip removal air duct section 3. Under the action of the cyclone separator, the drying air flow is separated from the hair debris; when the drying air flow contains a small amount of hair debris or no hair debris, the transition air duct section 4 is connected to the condensing air duct section 22 and the heating air duct section 21, and the drying air flow in the condensing air duct section 22 can smoothly enter the heating air duct section 21 through the transition air duct section 4.

[0075] To address the problem of complex structure required for the condensation air duct section 22 to communicate with the chip removal air duct section 3 or the transition air duct section 4, this embodiment proposes that the chip removal air duct section 3 is communicated with the condensation air duct section 22 via the chip removal air inlet 31, and the transition air duct section 4 is communicated with the condensation air duct section 22 via the transition air inlet 41;

[0076] The drying system further includes a baffle 5 and a baffle motor. The baffle 5 is rotatably disposed between the chip removal air inlet 31 and the transition air inlet 41 for switching between the chip removal air duct section 3 and the transition air duct section 4. The baffle 5 has a chip removal position in which the chip removal air inlet 31 is opened and the transition air inlet 41 is closed, and a transition position in which the chip removal air inlet 31 is closed and the transition air inlet 41 is opened. The baffle motor is drive-connected to the baffle 5, and the baffle motor drives the baffle 5 to rotate, thereby reaching the chip removal position or the transition position.

[0077] When the drying air flow contains a large amount of hair debris, the baffle 5 is placed in the chip removal position, and the drying air flow in the condensing air duct section 22 can enter the heating air duct section 21 through the chip removal air duct section 3, and the hair debris therein can be separated out by the cyclone separator; when the drying air flow contains a small amount of hair debris or no hair debris, the baffle 5 is placed in the transition position, and the drying air flow in the condensing air duct section 22 can smoothly enter the heating air duct section 21 through the transition air duct section 4, thereby increasing the circulation speed of the drying air flow in the drying air flow circuit and further improving the drying efficiency.

[0078] Furthermore, the chip removal air duct section 3 includes a chip removal air inlet section, a cyclone cylinder 32 and a chip removal air outlet pipe 33; a separation chamber 321 is formed inside the cyclone cylinder 32, and a cyclone air inlet connected to the separation chamber 321 is formed on the side wall of the cyclone cylinder 32; a cyclone air outlet is formed on the top of the cyclone cylinder 32, and the cyclone air outlet is coaxially arranged with the axis of the cylindrical section; specifically, the separation chamber 321 includes a cylindrical section and a conical section, and the conical section is arranged at the bottom of the cylindrical section and connected to the cylindrical section; a cyclone air inlet is formed on the side wall of the cylindrical section, and the cyclone air inlet is close to the top of the cylindrical section and the air inlet direction of the cyclone air inlet is consistent with the tangent direction of the cylindrical section;

[0079] The chip removal air inlet section is connected to the chip removal air inlet 31 and the cyclone air inlet; the chip removal air outlet pipe 33 is arranged at the cyclone air outlet, one end of the chip removal air outlet pipe 33 extends into the separation chamber 321 and is connected to the separation chamber 321, and the other end of the chip removal air outlet pipe 33 is connected to the heating air duct section 21;

[0080] The drying airflow with hair chips enters the cylindrical section through the hair chip removal air inlet section and rotates around the axis of the cylindrical section; the hair chips have a large mass, and under the centrifugal action, they reach the side wall of the cylindrical section and enter the conical section along the side wall of the cylindrical section under the action of gravity; the drying airflow has a small mass, and under the centrifugal action, it reaches the axis of the cylindrical section and enters the heating air duct section 21 along the hair chip removal air outlet pipe 33, thereby realizing the separation of hair chips and drying airflow.

[0081] In addition, a cyclone chip outlet is formed at the bottom of the cyclone cylinder 32 and is connected to the separation chamber 321; the drying system also includes a chip collecting box 34, which is arranged at the cyclone chip outlet and has a chip collecting chamber formed therein, which is connected to the cyclone chip outlet; hair chips enter the chip collecting chamber through the cyclone chip outlet, are collected by the chip collecting chamber, and can be cleaned in time to avoid the hair chips from mixing with the drying airflow again; compared with the method of using a spray structure to clean hair chips, the hair chips are collected and cleaned in time by the chip collecting box 34, which has a simple structure and will not cause the problem of hair chips clogging the drainage pipe; specifically, a cyclone chip outlet is formed at the bottom of the conical section and is connected to the separation chamber 321.

[0082] In response to the problem that the cyclone separator has low separation efficiency and is unable to completely clean the hair debris in the drying airflow, this embodiment proposes that the cyclone separator also includes a cyclone fan 35, which is arranged at the cyclone air inlet and is used to provide cyclonic separation power to the drying airflow; the power of the cyclone fan 35 can be adjusted to adjust the separation efficiency of the cyclone separator; the power of the cyclone fan 35 can be intelligently adjusted according to the humidity, amount of hair debris and size of the drying airflow, thereby improving the separation efficiency of hair debris and drying airflow and avoiding the problem of loud noise caused by inappropriate power of the cyclone fan 35.

[0083] A heating element 23 is provided in the heating air duct section 21, and a drying fan 24 is provided on the heating air duct section between the heating element 23 and the chip removal air outlet pipe; the drying fan 24 is a low-pressure fan, and the cyclone fan 35 is a high-pressure fan;

[0084] When the drying air flow cooled by the condensing air duct section 22 is controlled to enter the heating air duct section 21 through the chip removal air duct section 3, the drying fan 24 and the cyclone fan 35 are turned on at the same time;

[0085] When the drying air flow cooled by the condensing air duct section 22 is controlled to enter the heating air duct section 21 through the transition air duct section 4, only the drying fan 24 is turned on.

[0086] <Clothing Processing Equipment>

[0087] This embodiment further provides a clothes processing device, comprising a housing 13, an outer drum 11, an inner drum 12, and any one of the above-described drying systems; the outer drum 11 is disposed in the housing 13, and a drying air outlet 111 is formed on the wall of the outer drum 11, and a drying air inlet 112 is formed at the opening of the outer drum 11; the inner drum 12 is rotatably disposed in the outer drum 11, and the inner drum 12 is used to carry clothes; specifically, a door seal is provided at the opening of the outer drum 11, and the door seal is formed with the drying air inlet 112;

[0088] One end of the condensing air duct section 22 away from the heating air duct section 21 is connected to the drying air outlet 111, and the end of the heating air duct section 21 away from the condensing air duct section 22 is connected to the drying air inlet 112; in this way, the outer cylinder 11, the inner cylinder 12, the condensing air duct section 22, the chip removal air duct section 3 and the heating air duct section 21 constitute a first drying air flow circuit, or the outer cylinder 11, the inner cylinder 12, the condensing air duct section 22, the transition air duct section 4 and the heating air duct section 21 constitute a second drying air flow circuit; the corresponding drying air flow circuit can be selected according to the amount of hair debris in the drying air flow.

[0089] Furthermore, the clothing processing device also includes a dander detection module, a humidity detection module, a timing module and a control module. The dander detection module is used to detect the amount of dander in the inner drum, the humidity detection module is used to detect the humidity of the drying airflow in the inner drum, and the timing module is used to calculate the running time of the drying process; the dander detection module, the humidity detection module and the timing module are all electrically connected to the control module, and the control module controls the rotation of the baffle 5 of the drying system according to the data transmitted by the dander detection module, the humidity detection module and the timing module, so that the condensation air duct section 22 is connected to the dander removal air duct section 3 or the condensation air duct section 22 is connected to the transition air duct section 4.

[0090] <Control Method>

[0091] like Figure 2As shown, this embodiment provides a drying control method for a clothes processing device, wherein the clothes processing device is the clothes processing device described above; the clothes processing device is provided with a drying process, and the drying control method includes:

[0092] S1, obtaining the amount of hair scraps in the inner cylinder 12;

[0093] S2. Determine the target air duct section based on the amount of debris;

[0094] S3, controlling the target air duct section to communicate with the condensation air duct section 22;

[0095] The target air duct section is the debris removal air duct section 3 or the transition air duct section 4; the amount of debris in the inner cylinder 12 is determined in real time or periodically;

[0096] Furthermore, S2 includes:

[0097] S21, determining the current level of the amount of hair debris in the inner drum 12 and comparing the current level with a first preset level;

[0098] S22. Determine the target air duct section based on the comparison result between the current level and the first preset level;

[0099] Specifically, the first preset level is 0.47.

[0100] Furthermore, S22 includes:

[0101] S221: If the current level is less than the first preset level, the target air duct section is determined to be transition air duct section 4; this indicates that the clothes processing apparatus is in the early stage of the drying process, and there is little or no lint in the drying airflow. Therefore, the drying fan 24 and the heating element 23 are turned on, and the drying airflow in the condensing air duct section 22 can smoothly enter the heating air duct section 21 through the transition air duct section 4.

[0102] S222. When the current level is greater than or equal to the first preset level, the target air duct section is determined to be the dander removal air duct section 3; this indicates that the clothing processing equipment is in the late stage of the drying process. As the moisture content of the clothes gradually decreases, the dry clothes rub and beat against each other in the inner drum 12, causing the clothing fibers to detach, thereby generating a large amount of dander; the drying fan 24 is turned off and the cyclone separation is turned on. The drying airflow in the condensing air duct section 22 can enter the heating air duct section 21 through the dander removal air duct section 3, and the dander therein is removed by the cyclone separator.

[0103] When the target air duct section is the chip removal air duct section 3, the drying control method further includes:

[0104] S4. Compare the current level with the second preset level;

[0105] S5. Determine the power of the cyclone fan 35 of the cyclone separator according to the comparison result between the current level and the second preset level;

[0106] Specifically, the second preset level includes preset level A, preset level B, and preset level C, and the preset level A, preset level B, and preset level C increase in order; the value range of preset level A is 0.47 to 1.06, the value range of preset level B is 1.06 to 1.51, and the value range of preset level C is 1.51 to 1.66;

[0107] Furthermore, S5 includes:

[0108] S51, when the current level is greater than or equal to the first preset level and less than or equal to the preset level A, the power of the cyclone fan 35 is P1;

[0109] S52, when the current level is greater than the preset level A and less than the preset level B, the power of the cyclone fan 35 is P2;

[0110] S53. When the current level is greater than or equal to the preset level B and less than or equal to the preset level C, the power of the cyclone fan 35 is P3; by intelligently adjusting the power of the cyclone fan 35 according to the amount of hair debris, the flow rate of the drying airflow in the separation chamber 321 is adjusted, thereby improving the drying efficiency.

[0111] To address the problem of inaccurate determination of the amount of lint leading to inability to clean lint in a timely manner, this embodiment proposes determining the amount of lint based on the progress of the drying process and the humidity of the drying airflow.
