Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of clothes treatment equipment, and in particular to a self-cleaning control method of clothes treatment equipment and clothes treatment equipment. BACKGROUND

[0002] In the drying process of clothes treatment equipment, clothes need to be continuously turned over in the drum. Fluff is generated due to the continuous friction between the drum and the clothes. In order to prevent the generated fluff from entering the circulating air duct of the clothes dryer and causing the evaporator to be blocked, a filter screen assembly is generally arranged in the path of the circulating air duct to intercept the fluff generated in the drying process.

[0003] The filter screen of the clothes treatment equipment is generally arranged directly below the support front shell. The filter screen assembly is detachably placed in the channel of the support front shell. The structure of the filter screen assembly is generally a mesh bag structure. High-temperature and high-humidity air in the circulating air duct enters the inside of the filter screen assembly from above the filter screen, and then passes through the filter screen to enter the evaporator. Therefore, the fluff in the circulating air duct is intercepted in the inside of the filter screen assembly.

[0004] The fluff generated in the drying process is attached to the filter screen, causing blockage and gradually reducing the drying efficiency. Therefore, the user needs to detach the filter screen assembly that intercepts the fluff after each drying is completed, and manually clean the fluff on the filter screen, which is time-consuming and laborious. If the user does not clean the filter screen in time, the clothes may not be dried. In the prior art, periodic checking is relied on to determine whether the filter screen is abnormal, or the abnormality of the filter screen is automatically detected to remind the user to manually clean the filter screen, but the fluff on the filter screen cannot be automatically cleaned.

The embodiments of the present application propose a self-cleaning control method for clothes processing equipment and clothes processing equipment. In the drying program, the running parameters of the fan are obtained, and the cleaning strategy of the cleaning module to the filter module is automatically controlled according to the running parameters of the fan, so as to realize the self-cleaning effect of the filter module.

[0076] The following will be described in detail with reference to the accompanying drawings. Figure 1 - the accompanying drawings Figure 16 The technical solutions of the embodiments will be described in detail. In the case of no conflict, the following embodiments and examples can be combined with each other.

[0077] EMBODIMENT

[0078] As Figures 1-16As shown, the first aspect of the embodiment of the present application proposes a self-cleaning control method of a clothes processing device, the clothes processing device comprising a drying air path and a fan, the fan being configured to provide power for airflow in the drying air path, the drying air path being provided with a filter assembly, the filter assembly comprising a filter module arranged in the drying air path, and a cleaning module 2 capable of reciprocating along the surface of the filter module 1, the filter module 1 being configured to filter lint in the drying air path, and the cleaning module 2 being capable of cleaning the surface of the filter module 1 when the cleaning program is started.

[0079] The self-cleaning control method comprises:

[0080] In the drying mode, the operating parameter of the fan is acquired, and the cleaning strategy of the cleaning module is determined according to the operating parameter of the fan.

[0081] The operating parameter of the fan comprises the rotating speed of the fan and / or the operating time of the fan, and the cleaning strategy of the cleaning module comprises the starting time of the cleaning program of the cleaning module and / or the running times of the cleaning program of the cleaning module and / or the interval duration of the cleaning module when executing adjacent two cleaning programs.

[0082] The clothes processing device in the embodiment of the present application can control the cleaning strategy of the cleaning module by acquiring the operating parameter of the fan when the drying mode is running, thereby realizing the self-cleaning effect of the filter module.

[0083] Specifically, the operating parameter of the fan is acquired, and the cleaning strategy of the cleaning module is determined according to the operating parameter of the fan, comprising:

[0084] The difference ΔN between the rotating speed N of the fan when starting and the current rotating speed N1 of the fan is calculated.

[0085] If the difference ΔN is greater than the first preset difference ΔN0, the cleaning program of the cleaning module is started.

[0086] If the difference ΔN is less than or equal to the first preset difference ΔN0, the cleaning program of the cleaning module is stopped.

[0087] Preferably, when the system detects that the current rotating speed N1 of the fan is less than or equal to 50 rpm, the self-cleaning program of the cleaning module is started to clean the filter module.

[0088] Further, the self-cleaning control method further comprises:

[0089] When the difference ΔN is greater than the first preset difference ΔN0, the operating duration t of the fan is acquired, and the interval duration of the cleaning module when executing adjacent two cleaning programs is determined according to the operating duration t.

[0090] The time period from the start of the operation of the fan to the start of the cleaning program of the cleaning module is the operating duration t of the fan.

[0091] That is, the clothes processing equipment system in the embodiment of the application detects that the current fan speed N1 is greater than the original speed N≤50 rpm, further acquires the running time t of the fan, and determines the interval time when the adjacent two cleaning procedures are executed according to the running time t.

[0092] The shorter the running time t is, the more dirty the filter module is in a shorter time, and therefore the interval time when the adjacent two cleaning procedures are executed should be shortened, that is, the cleaning times of the filter module in the drying mode are increased.

[0093] Specifically, the interval time when the adjacent two cleaning procedures are executed is determined according to the running time t, comprising:

[0094] If t

[0095] If t1≤t≤t2, the interval time when the adjacent two cleaning procedures are executed is determined as the second preset interval time T2, t2 is the second preset running time;

[0096] If t>t2, the interval time when the adjacent two cleaning procedures are executed is determined as the third preset interval time T3, t3 is the third preset running time;

[0097] Wherein, T1

[0098] Preferably, the first preset interval time T1 is 15 min, the second preset interval time T2 is 25 min, and the third preset interval time T3 is 40 min.

[0099] It is worth noting that in some alternative embodiments, the interval time when the adjacent two cleaning procedures are executed is determined according to the running time t, comprising:

[0100] The weight of the clothes in the clothes processing equipment is determined according to the running time t of the fan, and the interval time when the adjacent two cleaning procedures are executed is determined according to the weight of the clothes.

[0101] Specifically, the weight of the clothes in the clothes processing equipment is determined according to the running time t of the fan, and the interval time when the adjacent two cleaning procedures are executed is determined according to the weight of the clothes, comprising:

[0102] If t According to the first weight G1, the interval time when the adjacent two cleaning procedures are executed is determined as the first preset interval time T1, t1 is the first preset running time.

[0103] If t1≤t≤t2, the weight of the laundry in the laundry treatment apparatus is determined as a second weight G2, the interval length of the cleaning module when performing adjacent two cleaning procedures is determined as a second preset interval length T2 according to the second weight G2, and t2 is the first preset running length;

[0104] If t>t2, the weight of the laundry in the laundry treatment apparatus is determined as a third weight G3, the interval length of the cleaning module when performing adjacent two cleaning procedures is determined as a third preset interval length T3 according to the second weight G3, and t3 is the first preset running length;

[0105] Wherein G1>G2>G3, T1<T2<T3.

[0106] In combination Figure 2 When the laundry treatment apparatus is performing drying, the fan starts to run, the drum starts to rotate, and the system detects that the current rotation speed N1 of the fan is greater than the original rotation speed N≤50 rpm, the actual t required for the fan from starting to the rotation speed being reduced to 50 rpm is calculated.

[0107] When t<t1, the weight of the laundry in the drum is determined as 6-10 kg (i.e., the first weight G1 described above), the filter screen self-cleaning procedure is performed, and the filter screen self-cleaning procedure is performed every 15 min (i.e., the first preset interval length T1 described above) subsequently.

[0108] When t1≤t≤t2, the weight of the laundry in the drum is determined as 3-5 kg (i.e., the second weight G2 described above), the filter screen self-cleaning procedure is performed, and the filter screen self-cleaning procedure is performed every 25 min (i.e., the second preset interval length T2 described above) subsequently.

[0109] When t>t2, the weight of the laundry in the drum is determined as <3 kg (i.e., the third weight G2 described above), the filter screen self-cleaning procedure is performed, and the filter screen self-cleaning procedure is performed every 40 min (i.e., the third preset interval length T3 described above) subsequently.

[0110] That is, the weight of the laundry in the drum is classified according to the running length t, and different interval times of the cleaning module cleaning strategy are adopted according to different weight levels.

[0111] In any of the above embodiments, the self-cleaning control method further comprises:

[0112] When the difference ΔN>the first preset difference ΔN0, the drying length of the drying mode is adjusted according to the running length t of the fan, and the number of cleaning procedure runs of the cleaning module is determined based on the adjusted drying length and the interval length of the cleaning module when performing adjacent two cleaning procedures.

[0113] For example, when it is judged that the filter module has been contaminated in a short time, the total running time of the drying mode can be increased, and the interval time between two adjacent cleaning programs can be correspondingly shortened, so that the clothes processing equipment can dry the clothes more thoroughly.

[0114] In any of the above embodiments, the self-cleaning control method further comprises:

[0115] The fan is controlled to operate at a first output power w1 before the cleaning program of the cleaning module is started, and to operate at a second output power w2 after the cleaning program of the cleaning module is started{to improve the drying effect on the clothes};

[0116] Wherein w1 < w2;

[0117] The self-cleaning control method further comprises:

[0118] The resistivity H of the clothes in the clothes processing equipment is obtained, and if the resistivity of the clothes is less than or equal to a preset clothes resistivity H0{preferably, the drying degree of the clothes in the drum is judged by setting a conductive sheet}, the drying mode is ended.

[0119] In any of the above embodiments, the clothes processing equipment further comprises a lint discharge channel, one end of the lint discharge channel is communicated with the external environment of the clothes processing equipment, and the other end can be controlled to be communicated with or disconnected from the drying air path. When the lint discharge channel is communicated with the drying air path, the lint cleaned from the filter module 2 by the cleaning module 2 can be discharged, wherein the communication position of the lint discharge channel and the drying air path is located on one side of the length direction of the filter module, and the cleaning module comprises a cleaning part which can reciprocate along the length direction of the filter module to clean the surface of the filter module.

[0120] The self-cleaning control method further comprises:

[0121] When the cleaning program of the cleaning module is started, the lint discharge channel is controlled to be communicated with the drying air path, and the cleaning part of the cleaning module is controlled to reciprocate along the length direction of the filter module for one cycle.

[0122] Specifically, the method of controlling the cleaning part of the cleaning module to reciprocate along the length direction of the filter module for one cycle comprises:

[0123] The cleaning part of the cleaning module moves from a side far from the lint discharge channel and the drying air passage communication position to a side close to the lint discharge channel and the drying air passage communication position, and when the cleaning part moves to the side of the lint discharge channel and the drying air passage communication position, the communication between the lint discharge channel and the drying air passage is turned off, and when the cleaning part returns from the side close to the lint discharge channel and the drying air passage communication position to the side far from the lint discharge channel and the drying air passage communication position, the fan is switched from the second output power w2 to the first output power w1.

[0124] More specifically, in combination with the laundry treatment device structure provided in the above Figures 3-16 When the self-cleaning subprogram of the cleaning module is started, the stepper motor rotates clockwise by 90° to open the valve of the lint discharge channel, the output power of the fan is increased to w2>w1, and the driving motor is started to drive the pinion to rotate the gear, so that the lead screw rotates to drive the brush assembly to move from right to left, the lint on the filter screen of the filter module is swept by the brush, and in the case of relatively large wind, the lint scraped off by the brush is blown into the lint discharge channel and discharged out of the shell. When the brush assembly moves to the leftmost position, the light sensor triggers a signal to the system to reverse the motor, the stepper motor rotates counterclockwise by 90° to close the valve of the lint discharge channel, the driving motor is reversed, the brush assembly will move to the right, and when it moves to the rightmost position, the light sensor sends a stop signal to the system, the driving motor stops rotating, and the power of the fan is adjusted to w1, so that the automatic cleaning of the lint on the filter screen assembly is realized in one cycle.

[0125] The above process is repeatedly performed during the drying process, and when the conductive sheet arranged at the front end of the support front shell (which will be specifically described in the laundry treatment device structure below) detects that the resistivity of the laundry H is less than or equal to a preset value H0, it is determined that the laundry has been dried, the drying program is ended, and the machine is stopped

[0126] The second aspect of the embodiment of the present application provides a laundry treatment device as shown in Figures 3-16 The laundry treatment device comprises:

[0127] A drying air passage and a fan, the fan being configured to circulate air flow in the drying air passage;

[0128] A filter assembly, the filter assembly comprising a filter module arranged in the drying air passage, and a cleaning module capable of reciprocating along the surface of the filter module 1, the filter module 1 being configured to filter lint in the drying air passage, and the cleaning module being capable of cleaning the surface of the filter module 1 when a cleaning program is started;

[0129] The cleaning module adopts the self-cleaning control method mentioned above when cleaning the surface of the filter module 1 when the cleaning program is started.

[0130] Further, the laundry treating apparatus further comprises a lint discharging passage;

[0131] One end of the lint discharging passage is communicated with an external environment of the laundry treating apparatus, and the other end can be controlled to be communicated with or disconnected from the drying air passage, and when the lint discharging passage is communicated with the drying air passage, lint cleaned from the filter module 1 by the cleaning module 2 can be discharged, wherein the communication position of the lint discharging passage with the drying air passage is located at one side of the length direction of the filter module;

[0132] The cleaning module further comprises a cleaning part, which can reciprocate along the length direction of the filter module to clean the surface of the filter module.

When the amount of hair dust on the filter screen 13 reaches a certain amount, the cleaning part 21 can be driven by the transmission part 22 to move along the filter screen mounting surface 12 to clean the filter screen 13 on the filter screen mounting surface 12, so that the self-cleaning effect of the filter screen 13 is realized.

[0176] Specifically, as shown in Figure 9 and Figure 10 , the filter screen mounting surface 12 is an inclined plane, and the transmission part 22 can drive the cleaning part 21 to reciprocate on the filter screen mounting surface 12 to clean the filter screen 13.

[0177] More specifically, as shown in Figure 9 and Figure 10 , the filter screen mounting surface 12 has a first edge 121 and a second edge 122 arranged oppositely, and the first edge 121 and the second edge 122 are sequentially connected to form the external contour of the filter screen mounting surface 12, and the extension direction of the first edge 121 is the length direction of the filter module 1.

[0178] The transmission part 22 can drive the cleaning part 21 to reciprocate on the filter screen mounting surface 12 along the length direction of the filter module 1 to clean the filter screen 13.

[0179] In any of the above embodiments, as shown in Figure 9 and Figure 10 , the filter module 1 comprises two filter screen mounting surfaces 12 arranged oppositely and obliquely, and each of the filter screen mounting surfaces 12 is provided with a filter screen 13.

[0181] Specifically, as shown in Figure 15 , the auxiliary holder body 212 comprises a holder part 2121 and an elastic brush piece 2122 arranged on the holder part 2121; preferably, the brush piece 2122 is a rubber brush piece.

[0182] As shown in Figure 16As shown, the brush blade 2122 has a fixed piece 21221 that is fixedly connected to the frame portion 2121 and a movable piece 21222 that protrudes from the frame portion 2121 for frictional engagement with the filter mounting surface 12;

When the cleaning part 21 moves, it can rub against the filter screen 13, thereby cleaning the filter screen 13.

[0191] It is worth noting that, in this embodiment of the invention, by setting the main body 221 as a hollow structure, the transmission part 22, when mounted on the filter module 1, will not significantly affect the speed of the airflow when it flows through the filter screen 13, thereby ensuring the filtration effect of the airflow.

[0192] Furthermore, such as Figure 14 As shown, the transmission unit 22 also includes:

[0193] The gear transmission structure 224 is connected to the lead screw 223 to drive the lead screw 223 to reciprocate.

[0195] As Figure 8 shown in the driving part 25, the driving part 25 is connected with the transmission part 22 to drive the cleaning part 21 to move through the transmission part 22.

[0196] Specifically, the gear transmission mechanism includes a shaft sleeve, a large gear and a shaft sleeve cover.

[0197] More specifically, the upper end of the brush holder is provided with a threaded hole, the lead screw 223 passes through the threaded hole of the upper end of the brush holder, and the two form a lead screw threaded transmission. The left and right ends of the lead screw are sleeved with shaft sleeves. Then put the lead screw 223 and the brush assembly combination into the cleaning bracket, cover the shaft sleeves with the shaft sleeve cover, fix them with screws, then fix the large gear at the right end of the lead screw 223, so that the lead screw 223 can rotate in the lead screw installation position to drive the brush holder to move left and right.

[0198] The driving part includes a driving motor, a main shaft and a pinion. The driving motor can drive the pinion to rotate through the main shaft.

[0200] The photoelectric sensor 23 includes two groups, which are arranged at the length direction of the two ends of the main part 221 of the transmission part 22, for limiting the stroke of the cleaning part 21 when moving on the lead screw 223.

[0201] The magnetic attraction structure 24 is provided with multiple groups, which are evenly distributed at the front and back of the main part 221 of the transmission part 22, for installing the transmission part 22 in the clothes treatment equipment.

[0202] In any of the above embodiments, as Figures 9-11 shown, the filter module comprises:

[0203] The filter screen holder 1a is a cavity structure with a narrow upper part and a wide lower part in longitudinal section. The side part of the filter screen holder forms a filter screen mounting surface that makes the filter screen holder narrow at the top and wide at the bottom, and the bottom part forms a first air inlet.

[0204] The bracket base 1b, the filter screen holder is seated on the bracket base, and the bracket base is provided with a second air inlet.

[0205] When the filter screen holder 1a is seated on the bracket base 1b, the first air inlet and the second air inlet are communicated to form an air outlet 11.

[0206] The bracket base is arranged in the embodiment of the application, so that the filter module 1 is conveniently installed in the first air duct section 31 of the clothes treatment equipment, and the stability of the filter module is also increased.

[0207] It should be noted that the first air duct section 31 is actually a filter screen installation groove formed in the support structure 3. Since other positions of the clothes treatment equipment are in a sealed state, air flow in the clothes treatment equipment can only pass through the groove structure, so the groove structure is part of the drying air path of the clothes treatment equipment and is used to realize the circulation of air flow.

[0208] Specifically, as shown in Figure 5 and Figure 6 , the support structure 3 includes a sealingly connected support front shell 32 and a bracket assembly 33, the bracket assembly 33 is formed with a clothes feeding opening 34, and the bottom position of the clothes feeding opening 34 is formed with the first air duct section 31.

[0209] In any of the above embodiments, the clothes treatment equipment is a drum-type clothes dryer.

[0210] In order to more clearly understand the working principle of the filter assembly and the clothes treatment equipment in the embodiment of the application, the following will be specifically described in combination with Figures 1-16 :

[0211] The cleaning part is composed of a brush holder and a rubber brush piece. The brush holder is shaped the same as the filter module 1. As shown in Figure 15 , two ribs are arranged on the left and right sides of the brush holder, and a through hole with internal threads is arranged on the upper side. The front and back surfaces of the rubber brush piece close to the brush holder are both arc-shaped groove structures, so that the brush is more fitted when it is bent and pressed against the filter screen surface.

[0212] The filter screen support 1a is designed as a symmetrical right triangle structure or an isosceles triangle structure with a small upper side and a large lower side, and the width of the lower side is greater than or equal to about 4 mm. The filter screen 2 is arranged on the left and right sides of the filter screen support 1a, and the lower side of the filter screen support 1a is an open structure, as shown in Figure 10 .

[0213] As shown in Figure 11 , a reinforcing rib is arranged in the middle of the bracket base 1b to prevent the filter screen support 1a from being deformed in a concave manner when it is seated on the bracket base 1b. A sealing strip installation groove is arranged at the root of the filter screen support 1a, as shown in Figure 10 . The sealing strip installation groove is located below the filter screen. Figure 10 A lint collecting groove is arranged above the sealing groove, as shown in , and the collecting groove is located between the sealing strip installation groove and the filter screen, and is used to collect lint falling during the drying process.

[0214] The cleaning module 2 is composed of a cleaning support {i.e. the main body part 221 mentioned above}, a brush support, a brush piece 2122, a lead screw 223, a shaft sleeve, a large gear, a shaft sleeve cover, a magnetic attraction structure 24 {magnet}, a photoelectric sensor 24, and a magnetic attraction terminal. The lead screw 223 passes through the threaded hole in the upper end of the brush support, and the two form a threaded transmission of the lead screw. The left and right ends of the lead screw 223 are sleeved with shaft sleeves. Then the combination of the lead screw 223 and the brush support is placed in the cleaning support, and the shaft sleeves are covered with a shaft sleeve cover and fixed with screws. Then the large gear is fixed to the right end of the lead screw 223, so that the lead screw 223 can rotate in the cleaning support {i.e. the main body part 221 mentioned above} to drive the brush support to move the brush piece 2122 left and right. Magnets are evenly and equidistantly inlaid on the front and back of the cleaning support, and the photoelectric sensor 24 is installed on the left and right ends of the cleaning support to limit the brush assembly to the leftmost and rightmost positions.

[0215] As shown in Figure 5 and Figure 6 , the right side of the support front shell 32 is provided with a driving motor, the main shaft of which passes through the filter screen groove {i.e. the first air duct section 31 mentioned above} on the support front shell 32, and a pinion is installed at the end of the main shaft. The edge of the filter screen groove of the support front shell 32 is provided with a magnet corresponding to the magnet on the cleaning support, and the two are arranged with mutual attraction.

[0216] When the user puts the clothes into the drum of the clothes treatment equipment and starts the drying with a specific program, the filter module 1 needs to be inserted into the support front shell, and then the cleaning module 2 is mounted above the filter module 1. The magnet on the cleaning support {i.e. the main body part 221 mentioned above} and the magnet on the support front shell 32 are attracted to each other, and the large gear and the pinion are meshed with each other, so that the cleaning module 2 can be tightly connected with the support front shell 32.

[0217] The drum starts to rotate and the fan is turned on to drive the air into the drum from the small holes in the rear flange of the drum. At this time, the flow direction of the air is from the rear end of the drum to the front end and into the front filter assembly supporting the front shell 32. Since other positions are in a sealed state, the high-temperature and high-humidity air with lint can only pass through the filter screen 13 on both sides of the filter module 1 and then pass out from the opening at the bottom of the filter module 1, so that the lint is intercepted on the outer surface of the filter screen 13 on the filter module 1. When the system detects that there is enough lint on the filter screen 13, the driving motor is started to drive the pinion to rotate the gear, so that the lead screw 223 rotates to drive the brush holder to move from right to left (or from left to right), and the brush piece on the brush holder sweeps the lint on the surface of the filter screen. When the brush assembly moves to the leftmost side (or the rightmost side), the photoelectric sensor 23 triggers to send a signal to the system to reverse the motor, so that the driving motor is reversed, the brush holder moves in the opposite direction until it moves to the opposite side, the photoelectric sensor sends a signal to the system to stop, and the driving motor stops rotating, so that the lint on the filter screen 13 is automatically swept.

[0218] It is worth mentioning that the laundry treatment apparatus mentioned above in the embodiments of the present application is preferably a clothes dryer.
