Abstract
Description
Technical Field
[0001] The present application relates to the field of clothing processing, and in particular to a clothing processing device and a control method, device and storage medium thereof. Background Art
[0002] As the pace of life accelerates, people often need to dry clothes after washing in addition to washing them. For example, using a clothes dryer or a washer-dryer with a drying function to automatically dry the washed clothes can effectively save the time required for drying clothes.
[0003] In the related art, the drying principle of the clothing processing equipment is roughly as follows: under the action of the heating device, the dry air is heated by the heating device to form dry hot air, and then enters the drying barrel to exchange heat with the wet clothes, taking away the moisture in the clothes to form relatively humid hot air. The humid hot air is then condensed by the condensing device, and the moisture therein is condensed into water, and then discharged through the drain pipe. The condensed air becomes relatively dry cold air, which is redirected to the heating device under the action of the fan, and is heated to form dry hot air to enter the next cycle, and this cycle is repeated until the drying process is completed.
[0004] However, during the drying process, the hot air in the drying barrel will not only take away the moisture in the clothes, but also take away a small amount of fluff and other substances in the clothes. Therefore, a filter is generally required to filter the air entering the drying tunnel. The filter is generally a detachable filter, which requires the user to manually rinse it after the dryer is working, which is cumbersome to operate. A flushing device for flushing the filter can also be set on the clothing processing equipment. After the drying is completed, the flushing device can be controlled to automatically flush the foreign matter accumulated on the filter. Since the flushing device needs to be set separately, the manufacturing cost of the equipment is increased. Summary of the invention
[0005] In view of this, an embodiment of the present application provides a clothing processing device and a control method, device and storage medium thereof, which aim to achieve automatic flushing of the filter while saving the manufacturing cost of the device.

[0028] Based on the comparison between the detection signal and a set imbalance amount;
[0029] If the rotation speed fluctuation is smaller than the set unbalance amount, the inner drum is controlled to rotate in a first rotation speed mode.
[0030] In some embodiments, the method further comprises:
[0031] If the speed fluctuation is greater than or equal to the set imbalance amount, the step of controlling the inner drum of the clothing processing equipment to rotate in the first speed mode and controlling the flushing device of the clothing processing equipment to flush the filter is skipped, and the step of controlling the inner drum to rotate in the second speed mode and controlling the heating device to resume heating is executed.

[0056] The present application is further described in detail below in conjunction with the accompanying drawings and embodiments.
[0057] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.
[0058] Before explaining the control method of the clothing processing device in the embodiment of the present application, the clothing processing device involved in the embodiment of the present application is first introduced. The clothing processing device can be a dryer or a washer-dryer with a drying function, and the clothing processing device includes: an inner drum, a drying channel connected to the inner drum, a heating device, a fan, a filter and a flushing device. Among them, the inner drum is used to load the clothes to be processed; the heating device and the fan can be arranged in the drying channel, the heating device is used to heat the air flow in the drying channel, and the heating device can be a heating tube. The fan is used to introduce the air after the clothes are dried in the inner drum into the drying channel. The filter is used to filter foreign matter in the air. The flushing device is used to flush foreign matter on the filter, such as fluff and other materials accumulated on the filter.
[0059] For example, Figure 1As shown, the clothing treatment device includes a housing 1 and an outer barrel 5 and an inner barrel 6 arranged in the housing 1. The outer barrel 5 can be used to hold water. The inner barrel 6 is located in the outer barrel 5 and is used to load the clothes to be treated. The inner barrel 6 is connected to a driving motor (not shown in the figure) that drives it to rotate. A drying channel 11 connected to the inner barrel 6 is provided in the housing 1. A fan 2, a heating device 3 and a temperature sensor 4 for detecting the temperature are arranged in the drying channel 11. A plurality of through holes for water flow and / or air flow can be arranged on the inner barrel 6, and the air in the inner barrel 6 flows into the outer barrel 5. The outer barrel 5 is connected to the drying channel 11. Under the blowing action of the fan 2, the air flow enters the drying channel 11, and after being heated by the heating device 3, it flows into the inner barrel 6 to exchange heat with the clothes in the inner barrel 6 and take away the moisture on the clothes. In order to prevent the air after heat exchange with the clothes from carrying foreign matter such as fluff into the drying channel 11, a filter 7 and a flushing device 8 for flushing the filter 7 are arranged on the inlet side of the drying channel 11. As the fan 2 draws the air from the outer barrel 5 into the drying tunnel 11, foreign matter such as fluff carried in the air also gathers in the direction of the drying tunnel with the flow of air and is adsorbed by the filter 7. The flushing device 8 can use water flow to flush foreign matter on the filter 7, thereby avoiding the trouble caused by the need to manually flush the filter 7. It can be understood that the filter 7 only needs to be able to filter foreign matter in the air. For example, a grid-shaped filter can be used. The specific structure of the filter 7 is not limited in this application. The flushing device 8 can be connected to a water source via a pipeline and flush the filter 7 under the control of a switch valve. The temperature sensor 4 can be an NTC (Negative Temperature Coefficient) sensor, which can be arranged in the drying tunnel 11 and located on the side of the heating device 3 away from the fan 2, thereby reducing the interference of the fan 2 on the temperature detection.
[0060] For example, Figure 2 As shown, the filter screen 7 is arranged at the top end of the rear side of the inner cylinder 6, and the flushing device 8 is arranged opposite to the filter screen 7 for supplying water and flushing the filter screen 7. The direction of the water flow is as shown in FIG. Figure 2 As shown by the solid arrow in , the water flow after flushing is discharged along the bottom end of the clothing processing device. It can be understood that during the drying process, the dry hot air entering the inner drum 6 from the outlet of the drying tunnel exchanges heat with the wet clothes, takes away the moisture in the clothes, and forms relatively humid hot air, which can be condensed by the water flow on the rear side of the inner drum 6, thereby achieving the effect of water condensation. That is, the flushing device 8 has the dual functions of flushing the filter 7 and condensing water on the humid hot air. It should be noted that the terms "front", "rear", "top", "bottom" and the like indicate the orientation or position relationship based on the orientation or position relationship shown in the accompanying drawings, which is only for the convenience of describing the present application and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application.
[0061] Exemplarily, the clothes processing device may further include: an air inlet 9 and an air outlet 10, the air inlet 9 is located at the entrance side of the drying tunnel, and is used to introduce air outside the clothes processing device; the air outlet 10 is used to guide part of the air (i.e., humid hot air) after drying clothes in the inner drum 6 to the outside of the clothes processing device. Since part of the humid hot air is directly discharged to the outside through the air outlet 10, and new air can be introduced into the drying tunnel through the air inlet 9, the moisture content in the air in the drying tunnel can be reduced, which is conducive to the air heated in the drying tunnel to enter the inner drum 6 again, thereby effectively taking away the moisture on the clothes and improving the drying efficiency.
[0062] It is understandable that the moist hot air discharged from the air outlet 10 is condensed by the outside air, that is, the clothes processing device can realize the combination of air condensation and water condensation at the washing device 8 to effectively condense the moist hot air discharged from the inner drum 6 during the drying process. Figure 2 As shown by the dotted arrow in .
[0063] like Figure 3 As shown, an embodiment of the present application provides a control method for a clothes processing device, which is applied in a drying stage, and the method includes:
[0064] Step 301, obtaining the temperature value of the drying channel of the clothes processing equipment.
[0065] For example, for a separate drying control program, the clothes processing device may receive a user command inputted via a button, touch screen, or remote control to enter the drying stage. For a washer-dryer, the clothes processing device may automatically enter the drying stage based on the stage in which the control program is running. For example, after running the control programs corresponding to the washing, rinsing, and dehydration stages, the clothes processing device may automatically enter the control program corresponding to the drying stage, thereby entering the drying stage.
[0066] Generally speaking, when the clothing processing equipment enters the drying stage, the heating device and the fan are both turned on. Driven by the fan, the air enters the drying tunnel and is heated by the heating device to exchange heat with the clothes in the inner drum, taking away moisture from the clothes to form humid hot air. After some of the humid hot air is mixed with the external air, it is brought into the drying tunnel again by the fan to enter the next cycle.
[0067] Here, the clothes treating apparatus may periodically obtain the temperature value of the drying channel detected by the temperature sensor.
[0068] Step 302: determine that the temperature value is greater than or equal to the first set temperature value, and control the heating device to stop heating.
[0069] In order to avoid damage to components and potential safety hazards caused by excessive temperature in the drying tunnel, the clothing processing device can compare the acquired temperature value with a first set temperature value, and if it is determined that the acquired temperature value is greater than or equal to the first set temperature value, the heating device is controlled to stop heating. The first set temperature value can be reasonably determined based on experiments, and for example, the first set temperature value can be 100°C.
[0070] Step 303 , determining that the temperature value is less than or equal to the second set temperature value, controlling the inner drum of the clothes processing equipment to rotate at a first speed mode, and controlling the flushing device of the clothes processing equipment to flush the filter.
[0071] It should be noted that the first set temperature value is greater than the second set temperature value. For example, the range of the inner drum operating speed in the first speed mode can be 80 to 200 rpm (revolutions per minute), and the second set temperature value can be 80°C, 85°C, 90°C or 95°C, etc. Those skilled in the art can reasonably set the operating speed of the first speed mode and the second set temperature value according to needs.
[0072] It is understandable that if the clothing processing device determines that the acquired temperature value is less than or equal to the second set temperature value, the inner drum can be controlled to rotate in the first speed mode. It should be noted that in the first speed mode, the operating speed of the inner drum is higher than the inner drum speed in the traditional drying mode. At this time, since the temperature in the drying tunnel has dropped, controlling the inner drum to operate in the first speed mode can make the clothes in the inner drum close to the inner wall. When the load is large, the air volume of the hot air flowing through the inner drum can be effectively increased, and the structural parts will not be damaged due to the excessive temperature of the hot air. And the inner drum rotates in the first speed mode, which can prevent the water flow of the flushing device from entering the inner drum through the through hole on the inner drum in the outer barrel. The water flow can also condense the air to be entered into the drying tunnel, so that the flushing device has the dual functions of flushing the filter and condensing water on the air, so that there is no need to set up a separate structure for flushing the filter, and it can be shared with the water supply device for water condensation, which is conducive to saving the manufacturing cost of the clothing processing device.
[0073] The embodiment of the present application uses a control strategy based on the temperature value of the drying tunnel, which is different from the control strategy of cleaning the filter when the fan stops during the drying stage in the related art. Based on the control strategy of the present application, the flushing device can flush the filter after the heating device is turned off, and condense the air to enter the drying tunnel, so that the flushing device has the dual functions of flushing the filter and condensing water on the air. When the flushing device is working, the inner drum rotates in the first speed mode, which can prevent the water flow of the flushing device from wetting the clothes in the inner drum and improve the condensation efficiency of the air.
[0074] In some embodiments, controlling the inner drum to rotate at a first speed mode and controlling a flushing device of the laundry processing equipment to flush a filter screen includes:
[0075] It is determined that the rotation speed of the inner drum is greater than or equal to the set rotation speed, and the flushing device of the clothes processing equipment is controlled to flush the filter.
[0076] It is understandable that before the clothes processing device controls the flushing device to flush the filter, it can also determine whether the speed of the inner drum reaches the set speed. If it is determined that the speed of the inner drum is greater than or equal to the set speed, the flushing device is controlled to flush the filter, for example, the switch valve is controlled to be turned on so that the water flow flushes the filter. In this way, after the speed of the inner drum meets the requirements, the flushing device can be turned on to flush the filter. At this time, due to the high speed of the inner drum, the water flow after flushing the filter can be prevented from entering the inner drum along the through holes on the inner drum to wet the clothes, and corresponding to the increase in the speed of the inner drum, the humid hot air discharged from the inner drum can be better condensed by the water flow after flushing the filter, thereby enhancing the effect of water condensation.
[0077] In some embodiments, before controlling the flushing device of the clothing processing equipment to flush the filter, the method further includes: controlling the fan to turn off; correspondingly, before controlling the heating device to resume heating, the method further includes: controlling the fan to turn on again.
[0078] Here, before the flushing device flushes the filter, the fan is controlled to be turned off, which can effectively prevent the water flow of the flushing device from being sucked into the drying tunnel by the fan, thereby reducing the risk of damage to the electrical components in the drying tunnel due to water immersion, etc. In addition, before the heating device resumes heating, the fan is turned on again, so as to protect the structural parts around the heating device and prevent the structural parts from being damaged by overheating, etc.
[0079] In some embodiments, controlling a flushing device of a laundry treatment device to flush a filter screen includes:
[0080] Control the flushing device to continuously flush the filter screen for a first set time period; or,
[0081] The flushing device is controlled to intermittently flush the filter until a second set time period is reached.
[0082] Here, the flushing device can flush the filter screen continuously or intermittently. For example, the switch valve is opened for 4 seconds to flush the filter screen, that is, the first set time is 4 seconds; or the switch valve is opened for 1 second and stopped for 5 seconds to flush the filter screen, and the 4 beats are repeated, that is, the second set time is 24 seconds. It should be noted that the control of the above flushing device is only an example, and the beat and / or duration of the flushing device flushing the filter screen can be reasonably adjusted according to the filter screen structure, the drying tunnel structure, the rotation speed of the inner drum, etc.
[0083] In some embodiments, before controlling the inner drum to rotate in the first speed mode, the method further includes:
[0084] Acquiring a detection signal representing the rotation speed fluctuation of the inner drum;
[0085] Based on the comparison between the detection signal and the set imbalance amount;
[0086] If the rotation speed fluctuation is smaller than the set unbalance amount, the inner drum is controlled to rotate in the first rotation speed mode.
[0087] It is understandable that, since the speed of the inner drum in the first speed mode is higher than that of conventional drying, the inner drum can be first subjected to an OOB (Out-Of-Balance) test to determine that the inner drum meets the OOB requirements before the inner drum is controlled to rotate in the first speed mode, thereby effectively avoiding dangerous conditions such as barrel collision during the drying process. Here, a detection signal representing the speed fluctuation can be obtained based on the speed sensor. For example, a detection signal corresponding to the speed fluctuation of the inner drum running at a specified speed for a set time is obtained, and compared with the set imbalance amount. If the speed fluctuation is less than the set imbalance amount, the inner drum is controlled to rotate in the first speed mode.
[0088] Exemplarily, if the speed fluctuation is greater than or equal to the set imbalance, the control of the inner drum to rotate in the first speed mode and the control of the washing device of the clothing processing equipment to wash the filter are skipped, and the control of the inner drum to rotate in the second speed mode and the control of the heating device to resume heating are executed. In this way, based on the advance OOB detection, the danger of hitting the barrel caused by the inner drum switching to the first speed mode can be avoided. Exemplarily, in the second speed mode, the value range of the inner drum operating speed can be 40 to 60 revolutions per minute (rpm).
[0089] In some embodiments, Figure 4 As shown, the control method of the clothes processing device also includes:
[0090] Step 304, controlling the inner drum to rotate at a second speed mode and controlling the heating device to resume heating.
[0091] It is understandable that during the process of flushing the filter screen by the flushing device, the inner drum rotates at the first speed mode, and after the flushing time of the flushing device reaches the set time, the current flushing is ended, and the heating device resumes heating, and the inner drum rotates at the second speed mode. It should be noted that if the fan is in the off state during the process of flushing the filter screen by the flushing device, the fan needs to be turned on again before the heating device resumes heating, so as to protect the structural parts around the heating device and avoid damage such as overheating of the structural parts.
[0092] Step 305, based on the acquired temperature value, repeatedly controls the heating device to stop heating, controls the inner drum of the clothing processing equipment to rotate in a first speed mode, controls the flushing device of the clothing processing equipment to flush the filter, controls the inner drum to rotate in a second speed mode, and controls the heating device to resume heating, until the clothing processing equipment exits the drying stage.
[0093] It is understandable that the laundry processing device repeatedly performs the aforementioned steps 302 to 304 based on the acquired temperature value until exiting the drying stage. The exit from the drying stage may be determined based on a set working time or based on whether the laundry meets the set drying conditions, which is not specifically limited here.
[0094] The clothing processing device of the embodiment of the present application, based on the aforementioned control method, can utilize the water flow of the flushing device to flush the filter during the drying stage to achieve condensation of the air to be entered into the drying channel, so that the flushing device has the dual functions of flushing the filter and condensing water on the air. Therefore, there is no need to set up a separate structure for flushing the filter, and the filter can be shared with the water supply device for water condensation, which is beneficial to saving the manufacturing cost of the clothing processing device, that is, the purpose of saving structural costs can be achieved based on program improvements.
[0095] In some embodiments, before the laundry processing device enters the drying stage, the method further includes:
[0096] Pre-drying and thermal dehydration of the clothes in the inner drum;
[0097] Among them, pre-drying is used to make the temperature in the inner drum reach the set temperature condition, and thermal dehydration is used to dehydrate the clothes after being heated in the inner drum.
[0098] It is understandable that before the clothing processing device performs the drying operation on the clothing in the inner drum, it can also perform pre-drying and thermal dehydration on the clothing in the inner drum. For example, in the pre-drying stage, the fan is turned on, the motor is controlled to drive the inner drum to operate in the second speed mode, the heating device starts heating, the temperature value detected by the temperature sensor at the drying channel is obtained, and the working state of the heating device is controlled based on the temperature value. For example, when the temperature value is greater than T1, the heating device is turned off, and when the temperature value is less than T2, the heating device resumes heating, where T1>T2. In the pre-drying stage, the main function is to increase the temperature in the inner drum, so as to improve the dehydration efficiency in the thermal dehydration stage.
[0099] The present application is described in further detail below in conjunction with application examples.
[0100] In this application example, the control method of the clothes processing equipment in the drying stage is as follows: Figure 5 As shown, including:
[0101] Step 401, the fan and the heating device are turned on.
[0102] After the clothes processing device enters the drying stage, the fan and the heating device are turned on, so that the fan and the heating device are both in operation. Exemplarily, the clothes processing device can also control the inner drum to operate in the aforementioned second speed mode first.
[0103] Step 402 , determining whether the temperature of the drying tunnel is greater than 100° C., if not, returning to step 401 , continuing to maintain the operation status of the fan and the heating device; if yes, executing step 403 .
[0104] Here, the temperature value of the drying tunnel is detected by a temperature sensor arranged at the drying tunnel, and a judgment is made based on the temperature value detected by the temperature sensor. If the temperature value is greater than 100°C (i.e., the first set temperature value mentioned above), the heating device needs to be turned off, otherwise, the heating state of the heating device continues to be maintained.
[0105] Step 403, turn off the heating device.
[0106] Step 404 , determining whether the temperature of the drying tunnel is less than 95° C. (ie, the aforementioned second set temperature value); if not, returning to step 403 , continuing to maintain the closed state of the heating device; if yes, executing step 405 .
[0107] Step 405, OOB detection.
[0108] Here, a detection signal corresponding to the speed fluctuation of the inner drum running at a specified speed for a set time period may be obtained, for example, a detection signal corresponding to the speed fluctuation running for 15 seconds.
[0109] Step 406 , determining whether the speed fluctuation meets the OOB requirement, if so, executing step 407 ; if not, executing step 411 .
[0110] Step 407, controlling the inner drum to operate in a first speed mode.
[0111] Here, if it is determined that the inner drum meets the OOB requirement, that is, the speed fluctuation is less than the set unbalance amount, the fan is turned off and the inner drum is controlled to operate in the first speed mode. Exemplarily, in the first speed mode, the inner drum can rotate forward and reverse alternately, for example, based on a rhythm of running at a speed of 200 rpm for 20 seconds and pausing for 5 seconds, and then rotating forward and reverse alternately.
[0112] Step 408, determine whether the rotation speed of the inner drum is greater than the set rotation speed, if so, execute step 409; if not, maintain the operation of step 407.
[0113] Step 409, turn off the fan and control the flushing device to flush the filter.
[0114] It is understandable that before the clothing processing device controls the flushing device to flush the filter, it can also determine whether the speed of the inner drum reaches the set speed. If it is determined that the speed of the inner drum is greater than or equal to the set speed, the flushing device is controlled to flush the filter, for example, the switch valve is controlled to be turned on so that the water flow flushes the filter. It should be noted that when the flushing device flushes the filter, the fan can be turned off to prevent the water flow of the flushing device from being sucked into the drying tunnel by the fan. Exemplarily, when it is determined that the speed of the inner drum is greater than 195rpm and the rotation direction of the inner drum is counterclockwise, the flushing device can be controlled to flush the filter. At this time, the humid hot air discharged from the inner drum can be better condensed by the water flow after flushing the filter, thereby enhancing the effect of water condensation. The flushing device flushes the filter and can continue to flush the filter for t1 seconds, and then end the flushing. Accordingly, the fan stops synchronously for t1 seconds. The value of t1 can be determined based on experiments, for example, t1=4.
[0115] Step 410, controlling the fan to resume operation;
[0116] Here, after the flushing device finishes flushing, the fan can be controlled to resume opening.
[0117] Step 411, controlling the inner drum to operate in a second speed mode.
[0118] For example, in the second speed mode, the inner drum may rotate forward and reverse alternately, for example, it may rotate forward and reverse alternately based on a rhythm of running at a speed of 46 rpm for 20 seconds and pausing for 5 seconds.
[0119] Step 412, control the heating device to turn on, and return to step 402.
[0120] For example, the heating device can be controlled to be turned on after the fan is turned on for a set time in step 410, so that the heating device can be restored after the fan is running stably. For example, after waiting for t2 seconds for the fan to be turned on again, the operation of the heating device is restored. The value of t1 can be determined according to experiments, for example, t2=5.
[0121] After the operation of the heating device is restored, the process returns to step 402, and the cycle is repeated, so that during the drying process, the filter screen is rinsed by the rinsing device in the first speed mode, and the water in the rinsing device condenses the excess moisture in the air, thereby improving the user experience of the drying operation. In addition, there is no need to separately set up a structure for rinsing the filter screen, and the structure can be shared with the water supply device for water condensation, which is conducive to saving the manufacturing cost of the clothing processing equipment.
[0122] Figure 6 The control logic diagram of the drying stage is shown in FIG. Figure 6As shown, the heating tube (i.e., the heating device) has a heating (Heater on) state and a heating stop (Heater off) state, and the inner drum has a first speed mode (pattern1) and a second speed mode (pattern2). When the temperature value corresponding to the drying channel detected by the temperature sensor is greater than or equal to the first set temperature value, the heating tube is controlled to switch to the Heater off state, and when the temperature value detected by the temperature sensor is less than or equal to the first set temperature value, the inner drum is switched to pattern1, and the flushing device flushes the filter for t1 second. Correspondingly, the fan is synchronously stopped for t1 second and then turned on. When the fan is turned on for t2 seconds, the heating tube is switched to the Heater on state, the inner drum is switched to pattern2, and the aforementioned control logic is repeated based on the temperature value detected by the temperature sensor.
[0123] It should be noted that the clothing processing device can also time the running time of the drying stage. When the top removal running time reaches the set working time, the drying stage is exited, thereby ending the drying.
[0124] Exemplarily, before the clothing processing device performs the drying operation on the clothes in the inner drum, it can also perform cold spin drying, pre-drying and hot spin drying on the washed clothes in sequence. In this way, the water content of the clothes before entering the drying stage can be reduced, thereby shortening the operation time of the drying stage and improving the drying efficiency.
