Description

Technical Field

[0001] This invention relates to the field of fabric processing equipment technology, and in particular to a method for treating filter clogging in fabric processing equipment and a fabric processing equipment. Background Technology

[0002] Some existing fabric processing equipment has a circulating spray washing function, that is, the washing water in the fabric processing equipment can be recycled through a circulating spray device.

[0003] However, lint is generated during the washing process. To prevent lint from clogging the circulating spray device, a filter screen is usually installed in the circulating spray device. The filter screen can effectively isolate lint in the water.

[0004] However, if the lint on the filter screen accumulates to a certain extent and is not cleaned in time, it will affect the spray flow of the circulating spray device, thereby affecting the circulating spray effect. Summary of the Invention

[0005] To overcome the problem that untimely cleaning of the filter screen in existing fabric processing equipment can easily affect the circulating spray washing effect, this invention proposes a method for treating filter screen clogging in fabric processing equipment and a fabric processing device. This method involves installing a cleaning component in the circulating spray device that contacts the filter screen and rotates under the impact of water flow to clean the filter screen surface. By measuring the rotation frequency of the cleaning component, the degree of clogging on the filter screen surface can be reflected, enabling timely cleaning of the filter screen and avoiding the problem of poor circulating spray washing effect due to untimely cleaning.

[0006] The first aspect of this invention provides a method for treating filter screen clogging in a fabric processing device. The fabric processing device includes a fabric processing cylinder and a circulating spray device. The circulating spray device includes a cleaning chamber with a built-in filter screen. When the fabric processing cylinder drains water, the washing water can enter the cleaning chamber, pass through the filter screen, and then be discharged from the cleaning chamber. The circulating spray device also includes a cleaning component that is rotatably disposed in the cleaning chamber. The cleaning component can rotate under the impact of the water flow into the cleaning chamber and clean the surface of the filter screen by contacting it during rotation.

[0007] Filter clogging treatment includes:

[0008] When the fabric treatment tube drains water into the cleaning chamber, the actual rotation frequency of the cleaning component is obtained, and it is determined whether the actual rotation frequency is greater than the preset rotation frequency.

[0009] If the actual rotation frequency is greater than the preset rotation frequency, it is determined that the filter screen is not clogged.

[0010] If the actual rotation frequency is less than or equal to the preset rotation frequency, it is determined that the filter is clogged.

[0011] In the above technical solution, the fabric treatment equipment has a washing program, which includes a washing water circulation spray stage and a drainage stage. In the washing water circulation spray stage, the washing water in the fabric treatment drum can enter the cleaning chamber after being discharged and then be filtered by the filter screen in the cleaning chamber before being discharged back into the fabric treatment drum. In the drainage stage, the washing water in the fabric treatment drum can enter the cleaning chamber after being drained and then be filtered by the filter screen in the cleaning chamber before being discharged from the cleaning chamber.

[0012] Methods for dealing with clogged filters include:

[0013] During the washing water circulation spraying and drainage stages, the actual rotation frequency of the cleaning components is obtained.

[0014] If the actual rotation frequency is greater than the preset rotation frequency, it is determined that the filter screen is not clogged.

[0015] If the actual rotation frequency is less than or equal to the preset rotation frequency, it is determined that the filter is clogged.

[0016] In the above technical solution, the fabric treatment equipment has a filter self-cleaning program. When the fabric treatment equipment runs the filter self-cleaning program, the filter clogging treatment method includes:

[0017] Control the water inlet of the fabric treatment tube to the first preset water level, and control the fabric treatment tube to drain when the fabric treatment tube reaches the first preset water level;

[0018] When the fabric treatment drum is draining, the actual rotation frequency of the cleaning component is obtained, and the filter self-cleaning program is exited based on the comparison between the actual rotation frequency and the preset rotation frequency.

[0019] In the above technical solution, determining whether to exit the filter self-cleaning program based on the comparison between the actual rotation frequency and the preset rotation frequency includes:

[0020] If the actual rotation frequency is greater than the preset rotation frequency, the automatic filter cleaning program will exit.

[0021] If the actual rotation frequency is less than or equal to the preset rotation frequency, the filter self-cleaning program will be repeated.

[0022] In the above technical solutions, the methods for treating filter clogging include:

[0023] During the washing water circulation spraying stage of the fabric treatment equipment, the water level in the fabric treatment drum is controlled to be at the second preset water level, which is lower than the first preset water level.

[0024] Methods for dealing with clogged filters also include:

[0025] During the washing water circulation spraying stage, dirt and clogging information that characterizes the degree of dirt and clogging of the filter screen is obtained, and the filter screen self-cleaning program is activated based on the dirt and clogging information.

[0026] In the above technical solution, the dirt blockage information includes the comparison results of the actual rotation frequency of the cleaning parts and the preset rotation frequency obtained by the fabric treatment equipment during the operation of the washing water circulation spray stage.

[0027] Determine whether to activate the filter self-cleaning program based on the dirt and clogging information, including:

[0028] If the actual rotation frequency is greater than the preset rotation frequency, the filter self-cleaning program will not be activated.

[0029] If the actual rotation frequency is less than or equal to the preset rotation frequency, the filter self-cleaning program will be activated.

[0030] In the above technical solution, the fabric treatment equipment includes a circulating spray pipe that communicates with the cleaning chamber of the circulating spray device. When the fabric treatment equipment is in the washing water circulating spray stage, the washing water in the fabric treatment cylinder can be discharged into the circulating spray pipe and discharged back to the fabric treatment cylinder through the circulating spray pipe. The fabric treatment equipment obtains the actual water flow rate in the circulating spray pipe when it is in the washing water circulating spray stage.

[0031] The dirt and clogging information includes a comparison between the actual water flow rate and the preset water flow rate obtained when the fabric treatment equipment is operating in the washing water circulation spray stage;

[0032] Determine whether to activate the filter self-cleaning program based on the dirt and clogging information, including:

[0033] If the actual water flow rate is greater than the preset water flow rate, the filter self-cleaning program will not be activated.

[0034] If the actual water flow is less than or equal to the preset water flow, the filter self-cleaning program will be activated.

[0035] In the above technical solution, the dirt blockage information includes the comparison results of the actual rotation frequency of the cleaning component and the preset rotation frequency obtained by the fabric treatment equipment during the previous operation and drainage phase.

[0036] Determine whether to activate the filter self-cleaning program based on the dirt and clogging information, including:

[0037] If the actual rotation frequency of the cleaning component obtained during the previous drainage phase is greater than the preset rotation frequency, the filter self-cleaning program will not be activated.

[0038] If the actual rotation frequency of the cleaning element obtained during the previous drainage phase is less than or equal to the preset rotation frequency, the filter self-cleaning program will be activated.

[0039] The above-mentioned technical solutions for treating filter clogging also include:

[0040] During the drainage stage of the fabric processing equipment, the water inlet of the fabric processing cylinder is controlled to reach the first preset water level, and when the fabric processing cylinder reaches the first preset water level, the fabric processing cylinder is controlled to drain.

[0041] In the above technical solution, the washing process includes a washing water circulation spraying stage and a drainage stage executed sequentially.

[0042] Methods for dealing with clogged filters also include:

[0043] Before the fabric treatment equipment performs the washing water circulation spraying stage, the actual rotation frequency of the cleaning parts and the preset rotation frequency obtained during the drainage stage of the previous washing program are compared.

[0044] If the actual rotation frequency of the cleaning component obtained after the last drainage stage is greater than the preset rotation frequency, the filter self-cleaning program will not be started before the washing water circulation spray stage of the current washing program.

[0045] If the actual rotation frequency of the cleaning component obtained after the previous drainage stage is less than or equal to the preset rotation frequency, the filter self-cleaning program will be started before the washing water circulation spray stage of the current washing program.

[0046] The above-mentioned technical solutions for treating filter clogging also include:

[0047] When the fabric treatment equipment performs the filter self-cleaning program, it stops the water intake of the fabric treatment cylinder while controlling the drainage of the fabric treatment cylinder.

[0048] A second aspect of the present invention provides a fabric treatment apparatus, comprising:

[0049] Fabric treatment tube, used to hold garments to be treated;

[0050] The circulating spray device includes a cleaning chamber with a built-in filter screen and cleaning components. The cleaning chamber has an inlet and a first drain that are connected to the fabric treatment drum. The washing water in the fabric treatment drum can enter the cleaning chamber through the inlet and be discharged back into the fabric treatment drum through the first drain to perform circulating spray washing on the clothes to be treated in the fabric treatment drum.

[0051] The cleaning components inside the cleaning chamber can rotate under the impact of the incoming water flow and come into contact with the surface of the filter screen to clean the filter screen surface during rotation.

[0052] In the above technical solution, the filter screen includes a cylindrical mesh structure built into the cleaning chamber. The filter screen of the cylindrical mesh structure is arranged to form a cavity that communicates with the cleaning chamber through the filter screen holes. The cavity is connected to the first drain outlet.

[0053] The cleaning component includes a scraper that is fitted around the outer periphery of the filter screen and adheres to the outer periphery of the filter screen.

[0054] The scraper can be driven to rotate around the outer periphery of the filter screen when water enters the cleaning chamber, so as to scrape and clean the outer periphery of the filter screen.

[0055] In the above technical solution, the cleaning component also includes:

[0056] An impeller is built into the cleaning chamber, and the impeller and scraper are connected together;

[0057] When water enters the cleaning chamber, the impeller rotates under the impact of the incoming water flow, which drives the scraper to rotate around the outer circumference of the filter screen to scrape and clean the outer surface of the filter screen.

[0058] In the above technical solution, the fabric processing equipment also includes:

[0059] Sensors are used to detect and output rotational parameters that characterize the rotation frequency of the scraper blade;

[0060] The controller is used to determine whether the filter is clogged based on the rotation parameters.

[0061] In the above technical solution, the cleaning chamber also has a second drain outlet;

[0062] Fabric processing equipment also includes:

[0063] The water inlet pipe is connected between the water inlet of the cleaning chamber and the bottom of the fabric treatment drum, and is used to receive washing water from the fabric treatment drum.

[0064] The first drain pipe is connected between the first drain outlet of the cleaning chamber and the top of the fabric treatment cylinder, and is used to discharge the filtered washing water in the cleaning chamber back into the fabric treatment cylinder.

[0065] The second drain pipe is connected to the second drain outlet of the cleaning chamber and is used to drain the water from the cleaning chamber.

[0066] The inlet pipe, the first drain pipe, and the second drain pipe can all be controlled to open independently.

[0067] In the above technical solution, a first water pump is provided on the water inlet pipe. The first water pump is used to control whether the washing water in the fabric treatment drum is discharged into the cleaning chamber.

[0068] A second water pump is installed on the first drain pipe. The second water pump is used to control whether the filtered washing water in the cleaning chamber is discharged into the fabric treatment drum.

[0069] The fabric processing equipment also includes a water inlet valve, which is installed on the first drain pipe and positioned relative to the second water pump near the drain end of the first drain pipe.

[0070] In the above technical solution, the impeller and the filter screen are arranged correspondingly in the vertical direction, and the water inlet and the second drain outlet are arranged correspondingly to the impeller in the horizontal direction.

[0071] When the first drain pipe is closed, the washing water that enters the cleaning chamber through the inlet pipe can be discharged directly through the second drain pipe connected to the second drain outlet, and the other part can be discharged through the second drain pipe connected to the second drain outlet after being filtered by the filter screen.

[0072] In the above technical solution, the fabric processing equipment is a drum washing machine or a drum washer-dryer combo.

[0073] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art:

[0074] This invention proposes a method for treating filter clogging in a fabric processing device and a fabric processing device. The method involves installing a cleaning component in a circulating spray device that contacts the filter screen and rotates under the impact of water flow to clean the surface of the filter screen. By measuring the rotation frequency of the cleaning component, the degree of clogging on the surface of the filter screen can be reflected, thereby enabling timely cleaning of the filter screen and avoiding the problem of poor circulating spray washing effect due to untimely cleaning of the filter screen.

[0088] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of apparatuses and methods consistent with some aspects of the invention as detailed in the appended claims.

[0089] Currently available fabric processing equipment may have a circulating spray washing function, meaning the washing water in the fabric processing equipment can be recycled through a circulating spray device. However, lint is generated during the washing process. To prevent lint from clogging the circulating spray device, a filter screen is usually installed in the circulating spray device to effectively isolate lint from the water flow. However, if lint accumulates on the filter screen to a certain extent and is not cleaned in time, it will affect the spray flow rate of the circulating spray device, thus affecting the circulating spray effect. In this embodiment of the invention, a cleaning component is installed in the circulating spray device that contacts the filter screen and can rotate under the impact of water flow to clean the surface of the filter screen. By measuring the rotation frequency of the cleaning component, the degree of dirt clogging on the filter screen surface can be reflected, thereby enabling timely cleaning of the filter screen and avoiding the problem of poor circulating spray washing effect caused by the filter screen not being cleaned in time.

[0090] The following is in conjunction with the appendix Figure 1 -Attached Figure 6 The technical solution of this embodiment is described in detail. Unless otherwise specified, the following implementation methods and embodiments can be combined with each other.

[0091] Example

[0092] like Figures 1-6 As shown, the first aspect of this application proposes a method for treating filter clogging in a fabric processing device. The fabric processing device includes a fabric processing cylinder 10 and a circulating spray device 20. The circulating spray device 20 includes a cleaning chamber 202 with a built-in filter screen 201. When the fabric processing cylinder 10 drains water, the washing water can enter the cleaning chamber 202, be filtered by the filter screen 201, and then be discharged from the cleaning chamber 202. The circulating spray device 20 also includes a cleaning component 203 rotatably disposed in the cleaning chamber 202. The cleaning component 203 can rotate under the impact of the water flow into the cleaning chamber 202 and clean the surface of the filter screen 201 by contacting the filter screen 201 during rotation.

[0093] Filter clogging treatment includes:

[0094] When the fabric treatment cylinder 10 drains water into the cleaning chamber 202, the actual rotation frequency of the cleaning component 203 is obtained, and it is determined whether the actual rotation frequency is greater than the preset rotation frequency.

[0095] If the actual rotation frequency is greater than the preset rotation frequency, it is determined that the filter screen 201 is not clogged.

[0096] If the actual rotation frequency is less than or equal to the preset rotation frequency, it is determined that the filter screen 201 is clogged.

[0097] In this embodiment, a cleaning component 203 is provided in the circulating spray device 20 to contact the filter screen 201 and rotate under the impact of water flow to clean the surface of the filter screen 201. By obtaining the rotation frequency of the cleaning component 203 under the impact of water flow, the dirt and clogging of the filter screen 201 surface can be reflected, thereby enabling timely cleaning of the filter screen 201 and avoiding the problem of poor circulating spray washing effect caused by the filter screen 201 not being cleaned in time.

[0098] Furthermore, in some embodiments, the fabric treatment equipment has a washing program, which includes a washing water circulation spray stage and a drainage stage. In the washing water circulation spray stage, the washing water in the fabric treatment drum 10 can enter the cleaning chamber 202 after being discharged, and then be filtered by the filter screen 201 in the cleaning chamber 202 before being discharged back into the fabric treatment drum 10. In the drainage stage, the washing water in the fabric treatment drum 10 can enter the cleaning chamber 202 after being drained, and then be filtered by the filter screen 201 in the cleaning chamber 202 before being discharged from the cleaning chamber 202.

[0099] Methods for dealing with clogged filters include:

[0100] During the washing water circulation spraying stage and the drainage stage, the actual rotation frequency of the cleaning component 203 is obtained;

[0101] If the actual rotation frequency is greater than the preset rotation frequency, it is determined that the filter screen 201 is not clogged.

[0102] If the actual rotation frequency is less than or equal to the preset rotation frequency, it is determined that the filter screen 201 is clogged.

[0103] That is, the fabric processing equipment in this application embodiment can identify the degree of dirt clogging of the filter screen 201 in both the circulating spray stage and the drainage stage, so that the dirt clogging of the filter screen 201 can be detected in a timely manner under multiple programs.

[0104] Furthermore, in some embodiments, the fabric treatment equipment has a filter self-cleaning program, and when the fabric treatment equipment runs the filter self-cleaning program, the filter clogging treatment method includes:

[0105] Control the fabric treatment cylinder 10 to receive water up to the first preset water level, and control the fabric treatment cylinder 10 to drain water when it reaches the first preset water level.

[0106] When the fabric treatment cylinder 10 drains water, the actual rotation frequency of the cleaning component 203 is obtained, and the filter self-cleaning program is exited based on the comparison between the actual rotation frequency and the preset rotation frequency.

[0107] That is, when the fabric processing equipment in this application embodiment determines that the filter screen 201 is clogged, it can automatically run the filter screen self-cleaning program, without the need for manual cleaning of the filter screen 201.

[0108] Specifically, when the fabric processing equipment determines that the filter screen 201 is clogged, it controls the fabric processing cylinder 10 to enter water to the first preset water level, and controls the fabric processing cylinder 10 to drain water when the water level in the fabric processing cylinder 10 reaches the first preset water level, thereby using the impact force of the drained water flow to drive the cleaning component 203 to rotate and clean the surface of the filter screen 201.

[0109] It is worth noting that the first preset water level is higher than the water level of the fabric treatment equipment during normal washing of clothes. The reason for raising the drainage water level of the fabric treatment drum 10 under the filter self-cleaning program is to ensure that there is enough water in the fabric treatment drum 10 to drive the cleaning component 203 in the cleaning chamber 202 to rotate, thereby ensuring that the filter 201 can be cleaned. The first preset water level is in the range of 1 / 8 to 1 / 2 of the fabric treatment drum 10.

[0110] Furthermore, in some embodiments, determining whether to exit the filter self-cleaning program based on a comparison between the actual rotation frequency and the preset rotation frequency includes:

[0111] If the actual rotation frequency is greater than the preset rotation frequency, the automatic filter cleaning program will exit.

[0112] If the actual rotation frequency is less than or equal to the preset rotation frequency, the filter self-cleaning program will be repeated.

[0113] When cleaning the filter screen 201, if the rotation frequency of the cleaning component 203 is greater than the preset rotation frequency, it indicates that the friction between the cleaning component 203 and the filter screen 201 is small, and the surface of the filter screen 201 is not seriously clogged. At this time, the filter screen self-cleaning program can be exited. If the rotation frequency of the cleaning component 203 is less than or equal to the preset rotation frequency, it indicates that the friction between the cleaning component 203 and the filter screen 201 is large, and the surface of the filter screen 201 is seriously clogged. At this time, it is necessary to control the water intake of the fabric treatment cylinder 10 to the first preset water level, and when the first preset water level is reached, the water is discharged again to impact the cleaning component 203 in the cleaning chamber 202, so that the cleaning component 203 rotates again to clean the surface of the filter screen 201 until the rotation frequency of the filter screen cleaning component 203 is greater than the preset rotation frequency.

[0114] Furthermore, in some embodiments, the method for treating filter clogging includes:

[0115] During the washing water circulation spraying stage of the fabric treatment equipment, the water level in the fabric treatment drum is controlled to be at the second preset water level, which is lower than the first preset water level.

[0116] Methods for dealing with clogged filters also include:

[0117] During the washing water circulation spraying stage, dirt and clogging information that characterizes the degree of dirt and clogging of the filter screen is obtained, and the filter screen self-cleaning program is activated based on the dirt and clogging information.

[0118] That is, the water level in the fabric treatment drum during the washing water circulation spraying stage of the fabric treatment equipment in this embodiment is lower than the water level in the fabric treatment drum under the filter self-cleaning program. Another reason for setting the water level in the fabric treatment drum 10 to be higher under the filter self-cleaning program is that some clothes have high water absorption, which may result in not much water in the fabric treatment drum 10. Therefore, when running the filter self-cleaning program, the water level in the fabric treatment drum 10 must be determined first, and a water level must be set to ensure that there is a suitable amount of water in the fabric treatment drum 10 to rinse the cleaning components in the cleaning chamber 202.

[0119] Furthermore, the dirt and clogging information includes the comparison results of the actual rotation frequency of the cleaning parts and the preset rotation frequency obtained by the fabric treatment equipment during the washing water circulation spray stage.

[0120] Determine whether to activate the filter self-cleaning program based on the dirt and clogging information, including:

[0121] If the actual rotation frequency is greater than the preset rotation frequency, the filter self-cleaning program will not be activated.

[0122] If the actual rotation frequency is less than or equal to the preset rotation frequency, the filter self-cleaning program will be activated.

[0123] This means that the rotation frequency of the cleaning components can be obtained during the circulating spray stage to determine whether the filter screen 201 is clogged.

[0124] Of course, in some alternative implementations, other methods can be used to determine whether the filter 201 is clogged.

[0125] For example, in one embodiment, the fabric treatment equipment includes a circulating spray pipe that communicates with the cleaning chamber of the circulating spray device. When the fabric treatment equipment is operating the washing water circulating spray stage, the washing water in the fabric treatment cylinder can be discharged into the circulating spray pipe and discharged back to the fabric treatment cylinder through the circulating spray pipe. The fabric treatment equipment obtains the actual water flow rate in the circulating spray pipe when operating the washing water circulating spray stage.

[0126] The dirt and clogging information includes a comparison between the actual water flow rate and the preset water flow rate obtained when the fabric treatment equipment is operating in the washing water circulation spray stage;

[0127] Determine whether to activate the filter self-cleaning program based on the dirt and clogging information, including:

[0128] If the actual water flow rate is greater than the preset water flow rate, the filter self-cleaning program will not be activated.

[0129] If the actual water flow is less than or equal to the preset water flow, the filter self-cleaning process will be activated.

[0130] In other words, the water flow rate of the circulating spray pipeline during the circulating spray stage can be used to determine whether the filter screen 201 is clogged.

[0131] For example, in one embodiment, the dirt clogging information includes a comparison between the actual rotation frequency of the cleaning component and the preset rotation frequency obtained during the previous drainage phase of the fabric treatment equipment operation.

[0132] Determine whether to activate the filter self-cleaning program based on the dirt and clogging information, including:

[0133] If the actual rotation frequency of the cleaning component obtained during the previous drainage phase is greater than the preset rotation frequency, the filter self-cleaning program will not be activated.

[0134] If the actual rotation frequency of the cleaning element obtained during the previous drainage phase is less than or equal to the preset rotation frequency, the filter self-cleaning program will be activated.

[0135] In other words, the frequency of rotation of the cleaning components obtained by the fabric treatment equipment in the previous drainage stage can also be used to determine whether the filter screen 201 is clogged.

[0136] Furthermore, in some embodiments, the filter clogging treatment method further includes:

[0137] During the drainage stage of the fabric processing equipment, the water inlet of the fabric processing cylinder is controlled to reach the first preset water level, and when the fabric processing cylinder reaches the first preset water level, the fabric processing cylinder is controlled to drain.

[0138] In order to ensure that the cleaning component 203 is effectively impacted by the water flow during the drainage stage, the water level in the fabric treatment tube 10 also needs to be raised to a higher level during the drainage stage so that enough water can enter the cleaning chamber 202 to drive the cleaning component 203 to rotate.

[0139] Furthermore, in some embodiments, the washing process includes a washing water circulation spraying stage and a drainage stage performed sequentially;

[0140] Methods for dealing with clogged filters also include:

[0141] Before the fabric treatment equipment performs the washing water circulation spraying stage, the actual rotation frequency of the cleaning parts and the preset rotation frequency obtained during the drainage stage of the previous washing program are compared.

[0142] If the actual rotation frequency of the cleaning component obtained after the last drainage stage is greater than the preset rotation frequency, the filter self-cleaning program will not be started before the washing water circulation spray stage of the current washing program.

[0143] If the actual rotation frequency of the cleaning component obtained after the previous drainage stage is less than or equal to the preset rotation frequency, the filter self-cleaning program will be started before the washing water circulation spray stage of the current washing program.

[0144] Based on the comparison between the actual rotation frequency of the cleaning components obtained during the previous drainage phase and the preset rotation frequency, the system controls whether to activate the filter self-cleaning program before the current washing water circulation spray phase. This saves water resources.

[0145] Furthermore, in some embodiments, the filter clogging treatment method further includes:

[0146] During the washing water circulation spraying stage and the drainage stage of the fabric treatment equipment, the water intake of the fabric treatment drum is stopped.

[0147] That is, during the washing water circulation spraying stage, when the water level in the fabric treatment drum reaches the second preset water level, the fabric treatment drum will stop taking in water. During the drainage stage, when the water level in the fabric treatment drum reaches the first preset water level, the fabric treatment drum will stop taking in water.

[0148] Furthermore, in some embodiments, the filter clogging treatment method further includes:

[0149] When the fabric treatment equipment performs the filter self-cleaning program, it stops the water intake of the fabric treatment cylinder while controlling the drainage of the fabric treatment cylinder.

[0150] Further, such as Figure 4 and Figure 5 As shown, a second aspect of this application also provides a fabric processing apparatus, comprising:

[0151] Fabric processing tube 10, used to hold the garments to be processed;

[0152] The circulating spray device 20 includes a cleaning chamber 202 with a built-in filter screen 201 and a cleaning component 203. The cleaning chamber 202 has a water inlet 2021 and a first drain outlet 2022 that are connected to the fabric treatment drum 10. The washing water in the fabric treatment drum 10 can enter the cleaning chamber 202 through the water inlet 2021 and be discharged back into the fabric treatment drum 10 through the first drain outlet 2022 to perform circulating spray washing on the clothes to be treated in the fabric treatment drum 10.

[0153] The cleaning component 203 inside the cleaning chamber 202 can rotate under the impact of the incoming water flow and come into contact with the surface of the filter screen 201 to clean the surface of the filter screen 201 during rotation.

[0154] In this embodiment, a cleaning component 203 is provided in the circulating spray device 20 to contact the filter screen 201 and rotate under the impact of water flow to clean the surface of the filter screen 201. By obtaining the rotation frequency of the cleaning component 203 under the impact of water flow, the dirt and clogging of the filter screen 201 surface can be reflected, thereby enabling timely cleaning of the filter screen 201 and avoiding the problem of poor circulating spray washing effect caused by the filter screen 201 not being cleaned in time.

[0155] Furthermore, in some embodiments, the filter screen 201 includes a cylindrical mesh structure built into the cleaning chamber 202. The filter screen 201 with the cylindrical mesh structure is configured to form a cavity that communicates with the cleaning chamber 202 through the filter screen holes. The cavity communicates with the first drain outlet 2022.

[0156] Cleaning component 203 includes a scraper 2031 that is sleeved on the outer periphery of filter screen 201 and adheres to the outer periphery of filter screen 201;

[0157] When water enters the cleaning chamber 202, the scraper 2031 can be driven to rotate around the outer periphery of the filter screen 201 to scrape and clean the outer periphery of the filter screen 201.

[0158] When the washing water in the fabric treatment drum 10 enters the cleaning chamber 202, the cleaning component 203 with scraper 2031 in the cleaning chamber 203 rotates under the impact of the water flow, thereby scraping and cleaning the outer peripheral surface of the filter screen 201.

[0159] Furthermore, in some embodiments, the cleaning component 203 also includes:

[0160] An impeller 2032 is built into the cleaning chamber 202, and the impeller 2032 and the scraper 2031 are connected together;

[0161] When water enters the cleaning chamber 202, the impeller 2032 can rotate under the impact of the incoming water flow, thereby driving the scraper 2031 to rotate around the outer periphery of the filter screen 201 to scrape and clean the outer periphery of the filter screen 201.

[0162] When the washing water in the fabric treatment cylinder 10 enters the cleaning chamber 202, the water flow impacts the impeller 2032, causing it to rotate. The impeller 2032 then drives the scraper 2031 to rotate, thereby achieving a cleaning effect on the surface of the filter screen 201.

[0163] Further optimization:

[0164] The aforementioned impeller is an inclined impeller, which can rotate on its own under the impact of the water flow at the inlet. The cleaning component is connected to a cleaning component motor, and a clutch mechanism is provided between the cleaning component motor and the impeller shaft. This clutch mechanism can be used to control the connection and disconnection of the cleaning component motor and the shaft. When the filter screen is severely clogged, in order to avoid overloading the cleaning component motor, the clutch mechanism can be controlled to disconnect the cleaning component motor and the shaft, so that the impeller rotates completely under the action of the water flow, creating a negative pressure effect at the inlet, thereby facilitating the rapid inflow and discharge of wastewater.

[0165] Furthermore, the drain valve at the second drain outlet can be controlled to open and close according to preset rules. For example, when the filter screen is severely clogged, the drain valve can be controlled to open and close intermittently at a certain rhythm to create an agitation effect on the water in the treatment chamber, so that more dirt can be shaken away with the water flow.

[0166] Furthermore, in some embodiments, the fabric treatment apparatus further includes:

[0167] Sensors are used to detect and output rotational parameters that characterize the rotation frequency of the scraper blade;

[0168] The controller is used to determine whether the filter screen 201 is dirty or clogged based on the rotation parameters.

[0169] Preferably, the sensor is an infrared sensor mounted on the impeller 2032, used to detect the rotation frequency of the impeller 2032.

[0170] Furthermore, in some embodiments, the cleaning chamber 202 also has a second drain outlet 2023;

[0171] Fabric processing equipment also includes:

[0172] Water inlet pipe 30 is connected between the water inlet 2021 of the cleaning chamber 202 and the bottom of the fabric treatment drum 10, and is used to receive washing water from the fabric treatment drum.

[0173] The first drain pipe 40 is connected between the first drain port 2022 of the cleaning chamber 202 and the top of the fabric treatment cylinder 10, and is used to discharge the filtered washing water in the cleaning chamber 202 back into the fabric treatment cylinder 10.

[0174] The second drain pipe 50 is connected to the second drain outlet 2023 of the cleaning chamber 202 and is used to drain the water in the cleaning chamber 202.

[0175] The inlet pipe 30, the first drain pipe 40, and the second drain pipe 50 can all be controlled to open independently.

[0176] Furthermore, in some embodiments, the cleaning chamber 202 also has a second drain outlet 2023;

[0177] Fabric processing equipment also includes:

[0178] Water inlet pipe 30 is connected between the water inlet 2021 of the cleaning chamber 202 and the bottom of the fabric treatment drum 10, and is used to receive washing water from the fabric treatment drum.

[0179] The first drain pipe 40 is connected between the first drain port 2022 of the cleaning chamber 202 and the top of the fabric treatment cylinder 10, and is used to discharge the filtered washing water in the cleaning chamber 202 back into the fabric treatment cylinder 10.

[0180] The second drain pipe 50 is connected to the second drain outlet 2023 of the cleaning chamber 202 and is used to drain the water in the cleaning chamber 202.

[0181] The inlet pipe 30, the first drain pipe 40, and the second drain pipe 50 can all be controlled to open independently.

[0182] Further, such as Figure 4As shown, a first water pump 301 is provided on the water inlet pipe 30. The first water pump 301 is used to control whether the washing water in the fabric treatment drum 10 is discharged into the cleaning chamber 202.

[0183] A second water pump 401 is provided on the first drain pipe 40. The second water pump 401 is used to control whether the filtered washing water in the cleaning chamber 202 is discharged into the fabric treatment drum 10.

[0184] The fabric processing equipment also includes a water inlet valve 402, which is disposed on the first drain pipe 40 and is located near the drain end of the first drain pipe 40 relative to the second water pump 401.

[0185] Furthermore, the impeller 2032 and the filter screen 201 are arranged correspondingly in the vertical direction, and the water inlet 2021 and the second drain outlet 2023 are arranged correspondingly to the impeller in the horizontal direction.

[0186] When the first drain pipe 40 is closed, the washing water that enters the cleaning chamber 202 through the water inlet pipe 30 can be discharged directly through the second drain pipe 50 connected to the second drain outlet 2023, and the other part can be discharged through the second drain pipe 50 connected to the second drain outlet 2023 after being filtered by the filter screen 201.

[0187] In any of the above embodiments, the fabric processing equipment is a drum washing machine or a drum washer-dryer combo.
