Description

Technical Field

[0001] This invention relates to the field of household appliance technology, and in particular to a clothing processing device and its control method. Background Technology

[0002] Currently, some clothing processing equipment with drying functions, such as dryers and washer-dryer combos, usually have a dust collection device installed on the equipment to remove dust from the drum and circulating air duct, thus achieving the dust removal function.

[0003] The dustbin of a vacuum cleaner often accumulates a lot of dust and dirt. If the dustbin is not cleaned in time, it can lead to poor ventilation, reduced suction power, increased energy consumption, and a negative impact on the user experience. Current technology typically requires users to disassemble the vacuum cleaner for manual cleaning, but due to its complex structure, disassembly is difficult and inconvenient, adding an extra burden to the user.

[0004] Therefore, there is an urgent need for a garment processing device and its control method to solve the above problems. Summary of the Invention

[0005] Based on the above problems, the purpose of this invention is to provide a garment processing device and its control method, which can improve the cleaning convenience of the vacuuming device of the garment processing device and reduce the maintenance difficulty.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] On the one hand, a garment processing device is provided, comprising:

[0008] The main body of the equipment is equipped with a garment processing chamber, a first air duct, and a second air duct.

[0009] A fan, the air outlet of which is connected to the air inlet of the garment processing chamber, and the first air duct selectively connects the air outlet of the garment processing chamber and the air inlet of the fan.

[0010] The vacuuming device is equipped with a dust collection chamber, which is connected to the air inlet of the fan. The second air duct selectively connects the air outlet of the clothing processing chamber and the dust collection chamber.

[0011] The control module is capable of selectively opening the first air duct and the second air duct according to the processing program of the garment processing equipment.

[0012] As an optional solution to the clothing processing device of the present invention, a first damper is provided on the first air duct and is communicatively connected to the control module. The first damper is used to control the opening and closing of the first air duct.

[0013] And / or, the second air duct is provided with a second air damper that is communicatively connected to the control module, and the second air damper is used to control the opening and closing of the second air duct.

[0014] As an optional embodiment of the clothing processing device of the present invention, the clothing processing device further includes a dust collection device detachably disposed on the main body of the device. The dust collection device is located between the air outlet of the first air duct and the air inlet of the fan, and the dust collection device is located between the dust suction device and the air inlet of the fan.

[0015] As an optional embodiment of the clothing processing device of the present invention, a pressure detection device is provided between the vacuuming device and the air inlet of the fan. The pressure detection device is communicatively connected to the control module and is used to detect the gas pressure downstream of the vacuuming device. The control module can control the opening and closing of the second air duct according to the detection value of the pressure detection device.

[0016] As an optional embodiment of the clothing processing device of the present invention, the main body of the device is provided with a third air duct, one end of the third air duct is connected to the first air duct, the other end is connected to the air inlet of the fan, and the dust collection chamber of the dust collection device is connected to the third air duct.

[0017] On the other hand, a control method for a garment processing device is provided, applied to the garment processing device described above, the control method comprising the following steps:

[0018] Obtain the processing program, and control the on / off state of the first air duct and the second air duct according to the processing program;

[0019] The processing procedure includes a cleaning procedure for cleaning the dust collection chamber, and the cleaning procedure includes the following steps:

[0020] Control the start of the fan;

[0021] When the working state of the fan reaches the preset state, control both the first air duct and the second air duct to switch to the disconnected state;

[0022] When the air pressure downstream of the dust collection device meets the preset conditions, the second air duct is controlled to switch to the conduction state so that the dust in the dust collection chamber is discharged under negative pressure.

[0023] As an optional embodiment of the garment handling equipment control method of the present invention, the cleaning procedure further includes the following steps:

[0024] The timing starts simultaneously when the second air duct is switched to the conduction state, and when the timing duration t reaches the preset duration t0, the recorded number of cleaning times N is incremented by 1;

[0025] Determine if the number of cleanup attempts N has reached N0; where N is an integer greater than or equal to 0, and N0 is an integer greater than or equal to 1.

[0026] If so, the cleaning procedure ends and the cleaning count N is reset to zero;

[0027] If not, the second air duct is switched to the disconnected state, and when the air pressure downstream of the dust collection device meets the preset condition, the second air duct is switched to the open state.

[0028] Repeat all the steps above.

[0029] As an optional solution to the clothing processing equipment control method of the present invention, the preset conditions include: the air pressure value downstream of the vacuuming device is greater than or equal to the air pressure threshold, and the air pressure threshold ranges from 300Pa to 350Pa.

[0030] And / or, the preset duration t0 is in the range of 5s≤t0≤60s.

[0031] As an optional solution to the clothing handling equipment control method of the present invention, the step of determining whether the working state of the fan has reached a preset state includes:

[0032] Obtain the fan's rotational speed or power information;

[0033] Determine whether the current speed of the fan is greater than or equal to a preset speed value, or determine whether the current power of the fan is greater than or equal to a preset power value; if so, determine that the working state of the fan has reached the preset state.

[0034] As an optional embodiment of the garment processing equipment control method of the present invention, the processing procedure includes a garment care procedure, which includes the following steps:

[0035] Control the fan to start, control the first air duct to switch to the conducting state, and control the second air duct to switch to the disconnected state;

[0036] And / or,

[0037] The processing procedure includes a dust removal procedure, which includes the following steps:

[0038] The fan is started, the first air duct is switched to the disconnected state, and the second air duct is switched to the connected state.

[0039] The beneficial effects of this invention are as follows:

[0040] The garment processing equipment and control method provided by this invention, when the first air duct is open and the second air duct is closed, forms a circulating air duct between the garment processing chamber, the first air duct, and the fan. When the garment processing equipment executes a corresponding processing program, such as a drying program, the drying airflow circulates within the circulating air duct under the action of the fan, thereby drying the garments in the garment processing chamber. When the second air duct is open and the first air duct is closed, forms a circulating air duct between the garment processing chamber, the second air duct, the dust collection device, and the fan. Under the action of the fan, dust in the garment processing chamber can enter the dust collection chamber of the dust collection device through the second air duct, achieving dust removal and reducing dust accumulation in the circulating air duct, thereby reducing drying energy consumption and improving drying efficiency.

[0041] When the cleaning program is executed, the first and / or second air ducts are kept in the open state before the fan reaches the preset operating state, so that a strong wind speed can be generated downstream of the dust collection device. When the fan reaches the preset operating state, the first and second air ducts are switched to the closed state. Under the action of the fan, the air pressure between the dust collection chamber of the dust collection device and the air inlet of the fan increases. When the air pressure meets the preset condition, the second air duct is opened. At the moment of opening, the airflow speed increases rapidly, causing the negative pressure in the dust collection chamber to increase instantaneously. The negative pressure area will attract the surrounding air and dust particles to move in the direction of airflow, thereby promoting the dust in the dust collection chamber to be discharged, achieving the purpose of cleaning the dust collection chamber.

[0042] In other words, by selectively controlling the first and second air ducts, the negative pressure generated by the garment processing equipment's own fan is used to automatically remove dust from the dust collection chamber. This eliminates the need to disassemble the vacuum cleaner for cleaning, simplifying the cleaning process and enabling a deep cleaning of the dust collection chamber. This ensures the vacuum cleaner's suction capacity, thereby guaranteeing the drying capacity of the garment processing equipment, preventing increased drying energy consumption due to excessive dust accumulation, and improving the user experience.

[0055] Example 1

[0056] like Figure 1 As shown, this embodiment provides a garment processing device, which includes a main body, a fan 1, a dust collection device 2, and a control module.

[0057] The main body of the equipment includes a clothing processing chamber 10, a first air duct 20, and a second air duct 30. The air outlet of the fan 1 is connected to the air inlet of the clothing processing chamber 10, and the first air duct 20 selectively connects the air outlet of the clothing processing chamber 10 and the air inlet of the fan 1. A dust collection device 2 is provided with a dust collection chamber, which is connected to the air inlet of the fan 1. The second air duct 30 selectively connects the air outlet of the clothing processing chamber 10 and the dust collection chamber. The control module can control the selective operation of the first air duct 20 and the second air duct 30 according to the processing program of the clothing processing equipment.

[0058] Specifically, when the first air duct 20 is open and the second air duct 30 is closed, a circulating air duct is formed between the garment processing chamber 10, the first air duct 20, and the fan 1. When the garment processing equipment executes a corresponding processing program, such as a drying program, the drying airflow circulates within the circulating air duct under the action of the fan 1, thereby drying the garments in the garment processing chamber 10. When the second air duct 30 is open and the first air duct 20 is closed, a circulating air duct is formed between the garment processing chamber 10, the second air duct 30, the dust collection device 2, and the fan 1. Under the action of the fan 1, dust in the garment processing chamber 10 can enter the dust collection chamber of the dust collection device 2 through the second air duct 30, achieving dust removal and reducing dust accumulation in the circulating air duct, thereby reducing drying energy consumption and improving drying efficiency.

[0059] When the cleaning procedure is executed, before the working state of the fan 1 reaches the preset state, the first air duct 20 and / or the second air duct 30 are kept in the conducting state so that a strong wind speed can be generated downstream of the dust collection device 2. When the working state of the fan 1 reaches the preset state, the first air duct 20 and the second air duct 30 are switched to the disconnected state. Under the action of the fan 1, the wind pressure between the dust collection chamber of the dust collection device 2 and the air inlet of the fan 1 increases. When the wind pressure meets the preset condition, the second air duct 30 is controlled to be opened. At the moment of opening, the airflow speed increases rapidly, causing the negative pressure in the dust collection chamber to increase instantaneously. The negative pressure area will attract the surrounding air and dust particles to move in the direction of airflow, thereby promoting the dust in the dust collection chamber to be discharged, achieving the purpose of cleaning the dust collection chamber.

[0060] That is, by selectively controlling the first air duct 20 and the second air duct 30, the negative pressure generated by the fan 1 of the clothing processing equipment is used to automatically remove dust from the dust collection chamber. There is no need to disassemble the vacuum cleaner 2 for cleaning, which simplifies the cleaning process and allows for deep cleaning of the dust collection chamber, ensuring the suction capacity of the vacuum cleaner 2. This, in turn, ensures the drying capacity of the clothing processing equipment, avoids increased drying energy consumption due to excessive dust accumulation, and improves the user experience.

[0061] Optionally, the garment processing equipment can be a dryer, a washer-dryer combo, a garment care machine, or other similar equipment. For example, if the garment processing equipment is a dryer, the main body of the equipment may include a housing and a roller disposed within the housing. The roller forms a garment processing chamber 10, and a first air duct 20 and a second air duct 30 are disposed within the housing.

[0062] Optionally, see Figure 1 The first air duct 20 is equipped with a first air damper 201, which is communicatively connected to the control module. The first air damper 201 is used to control the opening and closing of the first air duct 20. That is, by controlling the opening and closing of the first air damper 201, the opening and closing of the first air duct 20 is controlled, thereby achieving selective conduction of the first air duct 20. In addition, the air volume of the first air duct 20 can be adjusted by controlling the opening degree of the first air damper 201 to meet the air volume requirements of the garment processing equipment during different processing programs, precisely regulate airflow, avoid unnecessary energy loss, and improve the overall efficiency of the machine.

[0063] See Figure 1 The second air duct 30 is equipped with a second air damper 301, which is communicatively connected to the control module. The second air damper 301 is used to control the opening and closing of the second air duct 30. That is, by controlling the opening and closing of the second air damper 301, the opening and closing of the second air duct 30 is controlled, thereby achieving selective conduction of the second air duct 30. By controlling the opening degree of the second air damper 301, the air volume of the second air duct 30 can be adjusted, thereby adjusting the dust collection capacity of the dust collection device 2 to meet the dust collection needs under different working conditions.

[0064] For example, the control module can be the control circuit board of the garment processing equipment. The first damper 201 and the second damper 301 are both electric dampers, which facilitates the electric control of the opening and closing of the first air duct 20 and the second air duct 30, enhances the adaptability and flexibility of the control system, and improves the user experience.

[0065] See Figure 1 The garment processing equipment also includes a detachable dust collection device 4 installed on the main body of the equipment. The dust collection device 4 is located between the air outlet of the first air duct 20 and the air inlet of the fan 1, and between the vacuuming device 2 and the air inlet of the fan 1. On the one hand, when the first air duct 20 is open and the second air duct 30 is closed, the dust collection device 4 can filter and collect dust, lint, etc. generated during the corresponding processing procedure, preventing dust, lint, etc. from re-entering the garment processing chamber 10 and contaminating the garments, thus ensuring the garment care effect. On the other hand, during the cleaning procedure, the dust collection device 4 can also collect dust, lint, etc. discharged from the dust collection chamber of the vacuuming device 2. Since the dust collection device 4 is detachable from the main body of the equipment, the collected dust and other debris can be removed simply by disassembling and cleaning the dust collection device 4 later.

[0066] For example, the dust collection device 4 may be a lint filter or the like installed in the main body of the equipment.

[0067] See Figure 1 A pressure detection device 5 is installed between the vacuum cleaner 2 and the air inlet of the fan 1. The pressure detection device 5 is communicatively connected to the control module and is used to detect the gas pressure downstream of the vacuum cleaner 2. The control module can control the opening and closing of the second air duct 30 according to the detection value of the pressure detection device 5. Specifically, when the detection value of the pressure detection device 5 meets the preset conditions, the control module controls the second air duct 30 to switch to the conducting state. At the moment the second air duct 30 is opened, the airflow speed increases rapidly, and the negative pressure in the dust collection chamber increases instantaneously. Under the action of negative pressure, the dust in the dust collection chamber is discharged to the dust collection device 4. That is, the dust collection chamber of the vacuum cleaner 2 is deeply cleaned through the action of negative pressure, which can ensure the cleaning effect of the dust collection chamber.

[0068] Optionally, the preset condition can be that the detected value of the pressure detection device 5 is greater than or equal to the air pressure threshold. The air pressure threshold ranges from 300Pa to 350Pa. For example, the air pressure threshold can be 300Pa, 310Pa, 320Pa, 330Pa, 340Pa, 350Pa, etc., and can be adapted to factors such as the model and specifications of the fan 1.

[0069] For example, the pressure detection device 5 can be a pressure sensor, pressure gauge, etc., as long as it can detect the air pressure in the air duct.

[0070] See Figure 1 The main body of the device is equipped with a third air duct 40. One end of the third air duct 40 is connected to the first air duct 20, and the other end is connected to the air inlet of the fan 1. The dust collection chamber of the dust collection device 2 is connected to the third air duct 40. In this embodiment, the dust collection device 4 is located on the flow path of the third air duct 40. When the first air duct 20 is open and the second air duct 30 is closed, the airflow path is: clothing processing chamber 10 - first air duct 20 - third air duct 40 - fan 1 - clothing processing chamber 10. The dust collection device 4 filters and collects dust, lint, etc., on the airflow path. When the second air duct 30 is open and the first air duct 20 is closed, the airflow path is: clothing processing chamber 10 - second air duct 30 - dust collection chamber of the dust collection device 2 - third air duct 40 - fan 1 - clothing processing chamber 10. The dust collection device 4 filters and collects dust, lint, etc., on the airflow path.

[0071] Furthermore, the pressure detection device 5 is located on the flow path of the third air duct 40, and the pressure detection device 5 is located upstream of the dust collection device 4 to ensure the accuracy of the pressure detection results.

[0072] Example 2

[0073] like Figure 2As shown, this embodiment provides a control method for a garment processing device, applied to the garment processing device described in Embodiment 1. The control method for the garment processing device includes the following steps:

[0074] Obtain the processing program, and control the on / off state of the first air duct 20 and the second air duct 30 according to the processing program;

[0075] The processing procedure includes a cleaning procedure for cleaning the dust collection chamber, which includes the following steps:

[0076] S1, Control fan 1 to start;

[0077] S2. When the working state of the fan 1 reaches the preset state, control the first air duct 20 and the second air duct 30 to switch to the disconnected state.

[0078] S3. When the air pressure downstream of the dust collection device 2 meets the preset conditions, control the second air duct 30 to switch to the conduction state so that the dust in the dust collection chamber is discharged under negative pressure.

[0079] In step S2, before the working state of the fan 1 reaches the preset state, the first air duct 20 and / or the second air duct 30 are kept in the conducting state to ensure smooth airflow circulation and ensure that a strong wind speed can be generated downstream of the dust collection device 2, in preparation for the subsequent generation of negative pressure in the dust collection chamber of the dust collection device 2.

[0080] When the working state of the fan 1 reaches the preset state, it indicates that the wind speed in the circulating air duct is high enough. At this time, the control of the first air duct 20 and the second air duct 30 to switch to the disconnected state will gradually increase the air pressure between the dust collection chamber of the dust collection device 2 and the air inlet of the fan 1. When the air pressure increases to a certain value (i.e., the preset condition is met), the control of the second air duct 30 to open will rapidly increase the airflow speed and instantly increase the negative pressure in the dust collection chamber, thereby causing the dust in the dust collection chamber to be discharged under the action of negative pressure, achieving the purpose of cleaning the dust collection chamber.

[0081] By controlling the fan 1 to work in conjunction with the first air duct 20 and the second air duct 30, the dust collection chamber can be thoroughly cleaned without disassembling the vacuum cleaner 2, making cleaning and maintenance simple and improving the user experience.

[0082] Optionally, in step S2, the first air duct 20 is controlled by setting a first damper 201 on the first air duct 20, and the second air duct 30 is controlled by setting a second damper 301 on the second air duct 30.

[0083] Optionally, in step S3, refer to Figure 1A pressure detection device 5 is installed to detect the air pressure downstream of the vacuum cleaner 2. The pressure detection device 5 is communicatively connected to the control module. When the detected value of the pressure detection device 5 meets a preset condition, the control module controls the second air duct 30 to switch to the conducting state. For example, the pressure detection device 5 can be a pressure sensor, pressure gauge, etc., as long as it can detect the air pressure within the air duct.

[0084] Optionally, the preset conditions include: the air pressure value downstream of the dust collection device 2 is greater than or equal to the air pressure threshold, and the air pressure threshold ranges from 300Pa to 350Pa. When the detection value of the pressure detection device 5 reaches the air pressure threshold, it can ensure that the negative pressure in the dust collection chamber is large enough to completely discharge the dust in the dust collection chamber and meet the deep cleaning requirements of the dust collection chamber.

[0085] For example, the air pressure threshold can be 300Pa, 305Pa, 310Pa, 315Pa, 320Pa, 325Pa, 330Pa, 335Pa, 340Pa, 345Pa, 350Pa, etc., and is not limited to the values ​​listed above. The specific value can be selected adaptively according to factors such as the model and specifications of the fan 1.

[0086] In step S2, the step of determining whether the operating state of fan 1 has reached the preset state includes:

[0087] S21. Obtain the speed or power information of fan 1;

[0088] S22. Determine whether the current speed of fan 1 is greater than or equal to the preset speed value, or determine whether the current power of fan 1 is greater than or equal to the preset power value. If so, determine that the working state of fan 1 has reached the preset state.

[0089] Since the length of the circulating air duct is fixed when the first air duct 20 and / or the second air duct 30 are open, when the speed of the fan 1 reaches the preset speed or the power of the fan 1 reaches the preset power, it can be determined that the wind speed in the circulating air duct meets the requirements. At this time, after controlling the first air duct 20 and the second air duct 30 to switch to the disconnected state, the air pressure between the dust collection chamber of the dust collection device 2 and the air inlet of the fan 1 can be increased, thereby generating a large negative pressure in the dust collection chamber at the moment when the second air duct 30 switches to the open state.

[0090] When determining whether the operating state of fan 1 has reached a preset state by detecting the rotational speed of fan 1, for example, the preset rotational speed value ranges from 1000 rpm to 2000 rpm. For example, the preset rotational speed value can be 1300 rpm, 1400 rpm, 1500 rpm, 1600 rpm, 1800 rpm, etc., but is not limited to the values ​​and ranges listed above.

[0091] When determining whether the operating state of fan 1 has reached a preset state by detecting the power of fan 1, for example, the preset power value ranges from 1000W to 1500W. For example, the preset power value can be 1100W, 1200W, 1300W, 1400W, 1500W, etc., but is not limited to the values ​​and ranges listed above.

[0092] Example 3

[0093] This embodiment provides a control method for a garment processing device, which is a further improvement on Embodiment 2. The main difference is as follows:

[0094] like Figure 3 As shown, the cleaning procedure also includes the following steps:

[0095] S4. Start timing at the same time the second air duct 30 is switched to the conduction state, and increment the recorded number of cleaning times N by 1 when the timing duration t reaches the preset duration t0;

[0096] S5. Determine whether the number of cleanup attempts N has reached N0; where N is an integer greater than or equal to 0, and N0 is an integer greater than or equal to 1.

[0097] If so, the cleaning process ends and the cleaning count N is reset to zero;

[0098] If not, control the second air duct 30 to switch to the disconnected state, and when the air pressure downstream of the dust collection device 2 meets the preset conditions, control the second air duct 30 to switch to the open state.

[0099] S6. Repeat all the above steps.

[0100] In step S4, the initial value of the cleaning count N is 0. Each time the second air duct 30 switches to the conducting state and maintains it for a preset time t0, it is recorded as a completed cleaning, and the cleaning count N is incremented by 1. When the number of cleanings of the dust collection chamber reaches N0, the cleaning is completed, the cleaning program ends, and the recorded cleaning count N is reset to zero, ensuring that the initial value of the cleaning count N is 0 when the cleaning program is executed next time.

[0101] Optionally, the value of N0 can be 2, 3, 4, 5, etc., and users can set it on the control panel of the garment processing equipment according to their needs, without being limited to the values ​​listed above. By cleaning the dust collection chamber of the vacuum cleaner 2 multiple times, the dust in the dust collection chamber can be cleaned out, ensuring the vacuum cleaner 2's suction power.

[0102] Optionally, the preset duration t0 can be in the range of 5s ≤ t0 ≤ 60s. Controlling the second air duct 30 to be open and maintaining it for time t0 allows sufficient time for dust in the dust collection chamber to be carried out. In this embodiment, the preset duration t0 can be in the range of 10s ≤ t0 ≤ 30s. For example, t0 can be 10s, 15s, 20s, 25s, etc., but is not limited to the values ​​and ranges listed above.

[0103] Example 4

[0104] This embodiment provides a control method for a garment processing device, which is a further improvement on Embodiment 2. The main difference is as follows:

[0105] like Figure 4 As shown, the process also includes a garment care procedure, which includes the following steps:

[0106] Start the fan 1, switch the first air duct 20 to the conducting state, and switch the second air duct 30 to the disconnected state.

[0107] Specifically, the garment care program can be a drying program, a sterilization program, or a drum drying program, a drum self-cleaning program, or other programs that require the operation of the fan 1. When the garment care program is triggered, the first air duct 20 is opened and the second air duct 30 is closed, forming a circulating air duct between the garment processing chamber 10, the first air duct 20, and the fan 1. Under the action of the fan 1, the airflow circulates within the circulating air duct, achieving the purpose of drying and sterilizing the garments.

[0108] Furthermore, such as Figure 4 As shown, the processing procedure also includes a dust removal procedure, which includes the following steps:

[0109] Start the fan 1, switch the first air duct 20 to the off state, and switch the second air duct 30 to the on state.

[0110] The dust removal program runs after the garment processing program is completed, and is used to remove dust, lint, and other debris remaining in the garment processing drum and the circulating air duct. Specifically, when the dust removal program is triggered, the second air duct 30 is opened and the first air duct 20 is closed, forming a circulating air duct between the garment processing chamber 10, the second air duct 30, the dust collection device 2, and the fan 1. Under the action of the fan 1, the dust in the garment processing chamber 10 and the air duct can enter the dust collection chamber of the dust collection device 2 to remove dust, reduce the accumulation of dust in the circulating air duct, thereby reducing drying energy consumption and improving drying efficiency.
