[0003] However, during the washing process, dandruff is generated. In order to prevent the dandruff from clogging the circulating spray device, a filter is usually provided in the circulating spray device. The filter can effectively isolate the dandruff in the water path.

[0004] However, when the hair debris on the filter screen accumulates to a certain extent, if it 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] In order to overcome the problem that the filter in the existing fabric processing equipment is not cleaned in time and easily affects the circulating spray washing effect of the fabric processing equipment, the embodiment of the present invention proposes a method for processing the dirty and blocked filter of the fabric processing equipment and a fabric processing equipment, which provides a cleaning member in the circulating spray device, which contacts the filter and can rotate under the impact of water flow to clean the surface of the filter.

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

[0089] Some of the existing fabric processing equipment currently have a circulating spray washing function, that is, the washing water in the fabric processing equipment can be recycled through a circulating spray device. However, during the washing process, clothes will be accompanied by the generation of hair debris. In order to prevent the hair debris from clogging the circulating spray device, a filter is usually provided in the circulating spray device, and the filter can effectively isolate the hair debris in the waterway. However, when the hair debris on the filter accumulates to a certain extent, if it is not cleaned in time, it will affect the spray flow of the circulating spray device, thereby affecting the circulating spray effect. In the embodiment of the present invention, a cleaning part that contacts the filter and can rotate under the impact of water flow to clean the surface of the filter is provided in the circulating spray device. In this way, by obtaining the rotation frequency of the cleaning part during rotation, the dirt and blockage of the surface of the filter can be reflected, so that the filter can be cleaned in time, avoiding the problem of poor circulating spray washing effect caused by the failure to clean the filter in time.

[0090] The following is combined with Figure 1 -Attached Figure 6 The technical solution of this embodiment is elaborated in detail. In the absence of conflict, the following implementation methods and embodiments can be combined with each other.

[0091] Example

[0092] like Figure 1-Figure 6 As shown, in a first aspect, an embodiment of the present application proposes a method for treating filter screen clogging of a fabric treatment device, wherein the fabric treatment device comprises a fabric treatment drum 10 and a circulating spray device 20, wherein the circulating spray device 20 comprises a cleaning chamber 202 with a filter screen 201 built therein, wherein when the fabric treatment drum 10 is drained, washing water can enter the cleaning chamber 202 and be filtered by the filter screen 201 and then be discharged from the cleaning chamber 202, wherein the circulating spray device 20 further comprises a cleaning member 203 rotatably disposed in the cleaning chamber 202, wherein the cleaning member 203 can rotate under the impact of the water flow entering the cleaning chamber 202 and clean the surface of the filter screen 201 by contacting the filter screen 201 during rotation;

[0093] The treatment of filter blockage includes:

[0094] When the fabric treatment drum 10 drains water into the cleaning chamber 202, the actual rotation frequency of the cleaning member 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 201 is not dirty or blocked;

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

[0097] In the embodiment of the present application, a cleaning member 203 is provided in the circulating spray device 20, which is in contact with the filter 201 and can rotate under the impact of water flow to clean the surface of the filter 201. In this way, the dirt and blockage condition of the surface of the filter 201 can be reflected by obtaining the rotation frequency of the cleaning member 203 when it rotates under the impact of water flow, so that the filter 201 can be cleaned in time, thereby avoiding the problem of poor circulating spray washing effect caused by the filter 201 not being cleaned in time.

[0098] Further, in some embodiments, the fabric treatment device has a washing program, which includes a washing water circulation spraying stage and a drainage stage. In the washing water circulation spraying stage, the washing water in the fabric treatment drum 10 can enter the cleaning chamber 202 after being discharged and be filtered by the filter net 201 in the cleaning chamber 202 and then be discharged back to the fabric treatment drum 10 from the cleaning chamber 202. In the drainage stage, the washing water in the fabric treatment drum 10 can enter the cleaning chamber 202 after being drained and be filtered by the filter net 201 in the cleaning chamber 202 and then be discharged from the cleaning chamber 202;

[0099] The methods for dealing with dirty filter blockage include:

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

[0101] If the actual rotation frequency is greater than the preset rotation frequency, it is determined that the filter 201 is not dirty or blocked;

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

[0103] That is, the fabric processing device in the embodiment of the present application can identify the degree of dirtiness and blockage of the filter 201 whether in the circulating spraying stage or in the drainage stage, so that the dirtiness and blockage of the filter 201 can be discovered in time in multiple programs.

[0104] Further, in some embodiments, the fabric processing device has a filter self-cleaning program. When the fabric processing device runs the filter self-cleaning program, the filter dirty blockage treatment method includes:

[0105] Controlling the fabric treatment drum 10 to inlet water to a first preset water level, and controlling the fabric treatment drum 10 to drain water when the fabric treatment drum 10 reaches the first preset water level;

[0106] When the fabric treatment drum 10 is draining, the actual rotation frequency of the cleaning member 203 is obtained, and it is determined whether to exit the filter self-cleaning program based on the comparison result between the actual rotation frequency and the preset rotation frequency.

[0107] That is, when the fabric processing device in the embodiment of the present application determines that the filter 201 is dirty and clogged, it can automatically run the filter self-cleaning program without manual cleaning of the filter 201.

[0108] Specifically, when the fabric processing device determines that the filter 201 is dirty and clogged, it controls the fabric processing drum 10 to let water in to a first preset water level, and controls the fabric processing drum 10 to drain water when the water level in the fabric processing drum 10 reaches the first preset water level, thereby utilizing the impact force of the drained water flow to drive the cleaning element 203 to rotate and clean the surface of the filter 201.

[0109] It is worth noting that the first preset water level is higher than the water level of the fabric treatment device during normal washing of clothes, and 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 element 203 in the cleaning chamber 202 to rotate, thereby ensuring that the filter 201 can be cleaned, wherein the first preset water level is within the range of 1 / 8 to 1 / 2 of the fabric treatment drum 10.

[0110] Further, in some embodiments, determining whether to exit the filter self-cleaning program according to the comparison result 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 be exited;

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

[0113] That is, when cleaning the filter 201, if the rotation frequency of the cleaning member 203 is greater than the preset rotation frequency, it means that the friction between the cleaning member 203 and the filter 201 is relatively small, indicating that the surface of the filter 201 is not seriously dirty and clogged. At this time, the filter self-cleaning program can be exited; if the rotation frequency of the cleaning member 203 is less than or equal to the preset rotation frequency, it means that the friction between the cleaning member 203 and the filter 201 is relatively large, indicating that the surface of the filter 201 is seriously dirty and clogged. At this time, it is necessary to re-control the fabric processing cylinder 10 to allow water to enter the first preset water level, and when the first preset water level is reached, the water is discharged again to impact the cleaning member 203 in the cleaning chamber 202, so that the cleaning member 203 rotates again to clean the surface of the filter 201 until the rotation frequency of the filter cleaning member 203 is greater than the preset rotation frequency.

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

[0115] When the fabric treatment device is running in the washing water circulation spraying stage, the water level in the fabric treatment drum is controlled to be at a second preset water level, the second preset water level being lower than the first preset water level;

[0116] The methods for dealing with dirty filter blockage also include:

[0117] During the washing water circulation spraying stage, the clogging information characterizing the degree of clogging of the filter is obtained, and it is determined whether to start the filter self-cleaning program based on the clogging information.

[0118] That is, the water level in the fabric treatment drum of the fabric treatment device in the embodiment of the present application when executing the washing water circulation spraying stage is lower than the water level in the fabric treatment drum under the above-mentioned filter self-cleaning program. Another reason why the water level in the fabric treatment drum 10 is set 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 judged 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 flush the cleaning parts in the cleaning chamber 202.

[0119] Furthermore, the dirt and blockage information includes a comparison result between an actual rotation frequency of the cleaning element and a preset rotation frequency obtained when the fabric processing device is running the washing water circulation spraying stage;

[0120] Determine whether to start the filter self-cleaning program based on the dirty and blocked information, including:

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

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

[0123] That is, the rotation frequency of the cleaning element can be obtained during the cyclic spraying stage to determine whether the filter screen 201 is dirty or clogged.

[0124] Of course, in some alternative implementations, other judgment methods may be used to judge whether the filter screen 201 is dirty or clogged.

[0125] For example, in one embodiment, the fabric treatment device includes a circulating spray pipeline connected to the cleaning chamber of the circulating spray device. When the fabric treatment device is in the washing water circulating spray stage, the washing water in the fabric treatment drum can be discharged into the circulating spray pipeline and discharged back to the fabric treatment drum through the circulating spray pipeline. When the fabric treatment device is in the washing water circulating spray stage, the actual water flow rate in the circulating spray pipeline is obtained.

[0126] The dirt and blockage information includes the comparison result of the actual water flow rate and the preset water flow rate obtained when the fabric treatment equipment is running the washing water circulation spraying stage;

[0127] Determine whether to start the filter self-cleaning program based on the dirty and blocked 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 started;

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

[0130] That is, it is also possible to determine whether the filter screen 201 is dirty or clogged by obtaining the water flow rate of the circulating spray pipeline during the circulating spray stage.

[0131] For another example, in one embodiment, the dirt and blockage information includes a comparison result between the actual rotation frequency of the cleaning element and the preset rotation frequency obtained when the fabric processing device was in the last drainage phase;

[0132] Determine whether to start the filter self-cleaning program based on the dirty and blocked information, including:

[0133] If the actual rotation frequency of the cleaning element obtained during the last drainage phase is greater than the preset rotation frequency, the filter self-cleaning program will not be started;

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

[0135] That is, whether the filter screen 201 is dirty or clogged can also be determined by the rotation frequency of the cleaning element obtained by the fabric processing device in the last drainage stage.

[0136] Furthermore, in some embodiments, the filter screen dirty blockage treatment method further includes:

[0137] When the fabric treatment device performs a drainage phase, the fabric treatment drum is controlled to be filled with water to a first preset water level, and when the fabric treatment drum reaches the first preset water level, the fabric treatment drum is controlled to be drained.

[0138] That is, in order to enable the cleaning element 203 to be effectively impacted by the water flow during the drainage stage, the water level in the fabric treatment drum 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 element 203 to rotate.

[0139] Further, in some embodiments, the washing program includes a washing water circulation spraying phase and a drainage phase performed sequentially;

[0140] The methods for dealing with dirty filter blockage also include:

[0141] Before the fabric treatment device executes the washing water circulation spraying stage, obtaining a comparison result between the actual rotation frequency of the cleaning element obtained by the fabric treatment device during the drainage stage of the last washing program and the preset rotation frequency;

[0142] If the actual rotation frequency of the cleaning element obtained after the last drainage phase is greater than the preset rotation frequency, the filter self-cleaning program is not started before the washing water circulation spray phase of the current washing program is executed;

[0143] If the actual rotation frequency of the cleaning element obtained after the last drainage phase is less than or equal to the preset rotation frequency, the filter self-cleaning program is started before the washing water circulation spray phase of the current washing program is executed.

[0144] That is, according to the comparison result of the actual rotation frequency of the cleaning parts obtained during the last drainage stage and the preset rotation frequency, it is controlled whether to start the filter self-cleaning program before the execution of the current washing water circulation spray stage. This can save water resources.

[0145] Furthermore, in some embodiments, the filter screen dirty blockage treatment method further includes:

[0146] During the process of the fabric treating apparatus executing the washing water circulation spraying stage and the drainage stage, the water inlet to the fabric treating drum is stopped.

[0147] That is, in 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 no longer takes in water, and in the drainage stage, when the water level in the fabric treatment drum reaches the first preset water level, the fabric treatment drum no longer takes in water.

[0148] Furthermore, in some embodiments, the filter screen dirty blockage treatment method further includes:

[0149] When the fabric treatment device performs the filter screen self-cleaning program, the fabric treatment drum is controlled to drain water and the water intake to the fabric treatment drum is stopped at the same time.

[0150] Further, such as Figure 4 and Figure 5 As shown, the second aspect of the embodiment of the present application further provides a fabric processing device, comprising:

[0151] A fabric treatment drum 10, the fabric treatment drum 10 is used to contain clothes to be treated;

[0152] The circulating spray device 20 includes a cleaning chamber 202 with a filter 201 and a cleaning member 203 built therein. The cleaning chamber 202 has a water inlet 2021 and a first drain port 2022 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 into the fabric treatment drum 10 again through the first drain port 2022, so as to perform circulating spray washing on the clothes to be treated in the fabric treatment drum 10.

[0153] The cleaning member 203 in the cleaning chamber 202 can rotate under the impact of the incoming water flow, and contact the surface of the filter screen 201 during the rotation to clean the surface of the filter screen 201 .

[0154] In the embodiment of the present application, a cleaning member 203 is provided in the circulating spray device 20, which is in contact with the filter 201 and can rotate under the impact of water flow to clean the surface of the filter 201. In this way, the dirt and blockage condition of the surface of the filter 201 can be reflected by obtaining the rotation frequency of the cleaning member 203 when it rotates under the impact of water flow, so that the filter 201 can be cleaned in time, thereby avoiding the problem of poor circulating spray washing effect caused by the filter 201 not being cleaned in time.

[0155] Further, in some embodiments, the filter screen 201 includes a cylindrical mesh structure built into the cleaning chamber 202, and the filter screen 201 of the cylindrical mesh structure is surrounded by a cavity communicating with the cleaning chamber 202 through the filter mesh holes, and the cavity communicates with the first drain port 2022;

[0156] The cleaning member 203 includes a scraper strip 2031 which is sleeved on the outer periphery of the filter screen 201 and is in contact with the outer peripheral surface of the filter screen 201;

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

[0158] That is, when the washing water in the fabric treatment drum 10 enters the cleaning chamber 202 , the cleaning member 203 with the scraping bar 2031 in the cleaning chamber 202 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 member 203 further includes:

[0160] An impeller 2032 is built into the cleaning chamber 202, and the impeller 2032 and the scraper bar 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, so as to drive the scraper bar 2031 to rotate around the periphery of the filter screen 201 to scrape and clean the outer peripheral surface of the filter screen 201 .

[0162] That is, when the washing water in the fabric treatment drum 10 enters the cleaning chamber 202 , the water flow impacts the impeller 2032 to rotate, and the impeller 2032 drives the scraper 2031 to rotate, thereby achieving a cleaning effect on the surface of the filter screen 201 .

[0163] Further preferred:

[0164] The impeller is an inclined impeller, which can rotate automatically under the impact of the water flow at the water inlet. The cleaning part is connected to a cleaning part motor, and a clutch structure is provided between the cleaning part motor and the impeller shaft. The clutch structure can be used to control the connection and disconnection of the cleaning part motor and the shaft. When the filter is seriously dirty and blocked, in order to avoid overloading the cleaning part motor, the clutch mechanism can be controlled to disconnect the cleaning part motor and the shaft, so that the impeller rotates completely under the action of the water flow to form a negative pressure on the water inlet, thereby facilitating the rapid inflow and discharge of the stored sewage.

[0165] It may be further preferred that the drain valve at the second drain outlet can be controlled to switch on and off according to preset rules. For example, when the filter is dirty and the drainage is seriously blocked, the drain valve can be controlled to switch on and off intermittently with a certain opening and stopping rhythm, so as to produce a turbulent effect on the water in the processing chamber, so that more dirt can be discharged with the oscillation of the water flow.

[0166] Furthermore, in some embodiments, the fabric processing device further comprises:

[0167] A sensor, the sensor is used to detect and output a rotation parameter representing the rotation frequency of the scraper strip;

[0168] The controller is used to determine whether the filter screen 201 is dirty or blocked according to the rotation parameters.

[0169] Preferably, the sensor is an infrared sensor disposed on the impeller 2032 for detecting the rotation frequency of the impeller 2032 .

[0174] A second drain pipe 50, the second drain pipe 50 is connected to the second drain port 2023 of the cleaning chamber 202, and is used to drain the water in the cleaning chamber 202;

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

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

[0177] Fabric processing equipment also includes:

[0178] A water inlet pipe 30, which 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;

[0180] A second drain pipe 50, the second drain pipe 50 is connected to the second drain port 2023 of the cleaning chamber 202, and is used to drain the water in the cleaning chamber 202;

[0182] Further, such as Figure 4As shown, a first water pump 301 is provided on the water inlet pipe 30, and 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 disposed on the first drainage pipe 40, and 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 treating apparatus further includes a water inlet valve 402 , which is disposed on the first drainage pipe 40 , and the water inlet valve 402 is disposed close to a drainage end of the first drainage pipe 40 relative to the second water pump 401 .

[0185] Furthermore, the impeller 2032 and the filter screen 201 are arranged correspondingly in the up-down direction, and the water inlet 2021 and the second drain outlet 2023 are arranged correspondingly in the left-right direction with the impeller;

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