Detailed Description

The present application will be described in further detail with reference to the following drawings and examples.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein in the description of the present application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

Before the control method of the laundry treating apparatus according to the embodiment of the present application is explained, the laundry treating apparatus according to the embodiment of the present application will be described. The laundry treating apparatus, which may be a dryer or a washing and drying all-in-one machine having a drying function, includes: the drying tunnel, heating device, fan, filter screen and washing unit that inner tube, intercommunication inner tube. Wherein, the inner cylinder is used for loading the clothes to be treated; the heating device and the fan can be arranged in the drying tunnel, the heating device is used for heating the air flow in the drying tunnel, and the heating device can be a heating pipe. The fan is used for guiding air after the clothes are dried in the inner drum into the drying tunnel. The filter screen is used for filtering foreign matters in the air. The washing device is used for washing foreign matters on the filter screen, such as fluff and other matters accumulated on the filter screen.

Exemplarily, as shown in fig. 1, the laundry treating apparatus includes a cabinet 1, and an outer tub 5 and an inner tub 6 disposed in the cabinet 1, wherein the outer tub 5 can be used for holding water, the inner tub 6 is disposed in the outer tub 5 for loading laundry to be treated, and the inner tub 6 is connected to a driving motor (not shown) for driving the inner tub to rotate. A drying tunnel 11 communicated with the inner cylinder 6 is arranged in the box body 1, and a fan 2, a heating device 3 and a temperature sensor 4 for detecting temperature are arranged in the drying tunnel 11. The inner cylinder 6 may be provided with a plurality of through holes for water flow and/or air flow to pass through, and the air in the inner cylinder 6 flows into the outer cylinder 5. The outer barrel 5 is communicated with the drying tunnel 11, under the blowing action of the fan 2, airflow enters the drying tunnel 11, flows into the inner barrel 6 after being heated by the heating device 3, and exchanges heat with the clothes in the inner barrel 6 to take away moisture on the clothes. In order to prevent air after heat exchange with clothes from entering the drying tunnel 11 together with foreign matters such as lint, a filter 7 and a washing device 8 for washing the filter 7 are provided at an inlet side of the drying tunnel 11. As the fan 2 sucks the air in the tub 5 into the drying tunnel 11, foreign matters such as fluff carried in the air are gathered in the drying tunnel direction by the air flow and are adsorbed by the filter 7. The flushing device 8 can flush foreign objects on the sieve 7 with a water flow, thereby avoiding the trouble caused by the need to manually flush the sieve 7. It can be understood that the filter 7 only needs to be capable of filtering the foreign matters in the air, for example, a grid-shaped filter may be adopted, and the specific structure of the filter 7 is not limited in the present application. The flushing device 8 can be connected with a water source through a pipeline and can flush the filter screen 7 under the control of a switch valve. The Temperature sensor 4 may be an NTC (Negative Temperature Coefficient) sensor, and may be disposed in the drying tunnel 11 and located on a side of the heating device 3 away from the fan 2, so as to reduce interference of the fan 2 on Temperature detection.

Illustratively, as shown in fig. 2, a screen 7 is disposed at a rear top end of the inner drum 6, and a washing device 8 is disposed opposite to the screen 7 for supplying water and washing the screen 7, wherein the flow direction of the water flow is shown by solid arrows in fig. 2, and the washed water flow is discharged along a bottom end of the laundry treatment apparatus. It can be understood that, in the drying process, the hot air entering the inner drum 6 from the outlet of the drying tunnel for drying exchanges heat with wet clothes, and then takes away the moisture in the clothes to form relatively humid hot air, and the humid hot air can be condensed by the water flow at the rear side of the inner drum 6, so as to achieve the effect of water condensation. I.e. the flushing device 8 has the dual function of flushing the sieve 7 and of condensing water from the moist, hot air. It should be noted that the terms "front", "back", "top", "bottom", and the like, indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, are only used for convenience in describing the present application and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed in a specific orientation, and be operated, and thus should not be construed as limiting the present application.

Exemplarily, the laundry treating apparatus may further include: an air inlet 9 and an air outlet 10, wherein the air inlet 9 is positioned at the inlet side of the drying tunnel and is used for introducing air outside the clothes treatment equipment; the air outlet 10 is used for guiding out air (i.e. moist hot air) after drying the clothes in the inner drum 6 to the outside of the clothes treatment equipment. Because part of moist hot air is directly discharged to the outside from the air outlet 10, and new air can be introduced into the drying tunnel through the air inlet 9, the content of moisture in the air in the drying tunnel can be reduced, the air heated in the drying tunnel can enter the inner drum 6 again, so that the moisture on clothes can be effectively taken away, and the drying efficiency is improved.

It can be understood that the moist hot air discharged from the air outlet 10 is condensed by the external air, that is, the clothes treating apparatus can combine the air condensation with the water condensation at the washing device 8 to effectively condense the moist hot air discharged from the drum 6 during the drying process. Illustratively, the flow of air during drying is shown by the dashed arrows in fig. 2.

As shown in fig. 3, an embodiment of the present application provides a control method of a laundry treatment apparatus, applied to a drying stage, the method including:

step 301, obtaining a temperature value of a drying tunnel of the clothes processing equipment.

For example, for a control program of the individual drying, the laundry treating apparatus may receive an instruction input by a user based on a key, a touch screen, a remote controller, or the like to enter the drying stage. For the washing and drying integrated machine, the clothes treatment device can automatically enter the drying stage based on the stage of the operation of the control program, for example, after the control program corresponding to the washing, rinsing and dewatering stages is operated, the clothes treatment device automatically enters the control program corresponding to the drying stage, and then enters the drying stage.

Generally speaking, when the clothes processing equipment enters a drying stage, both the heating device and the fan are started, under the driving of the fan, air enters the drying tunnel and is heated by the heating device to carry out heat exchange on clothes in the inner drum, moisture on the clothes is taken away, moist hot air is formed, and after being mixed with external air, part of the moist hot air is taken into the drying tunnel by the fan again and enters the next cycle.

Here, the laundry treating apparatus may periodically acquire a temperature value of the drying tunnel detected by the temperature sensor.

Step 302, determining that the temperature value is greater than or equal to a first set temperature value, and controlling the heating device to stop heating.

In order to avoid device damage, potential safety hazards and the like caused by overhigh temperature in the drying tunnel, the clothes treatment equipment can compare the acquired temperature value with a first set temperature value, and if the acquired temperature value is determined to be greater than or equal to the first set temperature value, the heating device is controlled to stop heating. The first set temperature value may be reasonably determined based on experiments, and may be, for example, 100 ℃.

Step 303, determining that the temperature value is less than or equal to a second set temperature value, controlling the inner drum of the clothes treatment equipment to rotate in a first rotating speed mode, and controlling a washing device of the clothes treatment equipment to wash the filter screen.

It should be noted that the first set temperature value is greater than the second set temperature value. For example, the range of the operating speed of the inner cylinder in the first speed mode may be 80 to 200rpm (revolutions per minute), and the second set temperature value may be 80 ℃, 85 ℃, 90 ℃ or 95 ℃, and the like, and those skilled in the art may reasonably set the operating speed and the second set temperature value in the first speed mode according to requirements.

It can be understood that, if the laundry treating apparatus determines that the acquired temperature value is less than or equal to the second set temperature value, the drum may be controlled to rotate in the first rotation speed mode. It should be noted that, in the first rotation speed mode, the operation rotation speed of the inner drum is increased compared with the rotation speed of the inner drum in the conventional drying mode. At the moment, because the temperature in the drying tunnel is reduced to some extent, the inner drum is controlled to operate in the first rotating speed mode, so that clothes in the inner drum can be tightly attached to the inner wall, the air volume of hot air flowing through the inner drum can be effectively increased under the condition of large load capacity, and damage to structural members and the like due to overhigh temperature of the hot air is avoided. And the inner tube rotates with the first speed mode, can prevent the rivers of the flushing device from entering the inner tube through the through hole on the inner tube in the outer bucket, the rivers can also condense the air to be got into the drying tunnel, make the flushing device have the dual function of washing the filter screen and carrying on the water condensation to the air, thus can needn't set up the structure of washing the filter screen alone, realize with the sharing of the water supply installation of water condensation, do benefit to the manufacturing cost who practices thrift the treatment facility of clothing.

The embodiment of the application, control strategy based on the temperature value of drying tunnel, be different from the control strategy who washs the filter screen when the fan stall is confirmed in the stoving stage in the correlation technique, based on the control strategy of this application, can realize that washing unit closes the back at heating device, wash the filter screen, and treat the air that gets into the drying tunnel and carry out the condensation, make this washing unit have and wash the filter screen and carry out the dual function of water condensation to the air, and the washing unit during operation, the inner tube rotates with first rotational speed mode, can avoid washing unit's rivers to drench the clothing in the inner tube, and improve the condensation efficiency to the air.

In some embodiments, controlling the drum to rotate in the first rotation speed mode and controlling the washing unit of the laundry treating apparatus to wash the filter net includes:

and determining that the rotating speed of the inner drum is greater than or equal to the set rotating speed, and controlling a washing device of the clothes treatment equipment to wash the filter screen.

It can be understood that, before the laundry processing apparatus controls the washing device to wash the filter screen, it may also be determined whether the rotation speed of the inner drum reaches the set rotation speed, and if it is determined that the rotation speed of the inner drum is greater than or equal to the set rotation speed, the washing device is controlled to wash the filter screen, for example, the switch valve is controlled to be turned on, so that the water flow washes the filter screen. So, can open washing unit and wash the filter screen after the rotational speed of inner tube meets the demands, at this moment, because the rotational speed of inner tube is higher, can avoid the rivers after washing the filter screen to get into the inner tube along the through-hole on the inner tube and drench the clothing, and corresponding to the improvement of inner tube rotational speed, the rivers condensation behind the filter screen can be better washed to inner tube exhaust moist hot-air, and then the effect of reinforcing water condensation.

In some embodiments, before controlling the washing device of the laundry treatment apparatus to wash the sieve, the method further comprises: controlling the fan to be closed; correspondingly, before controlling the heating device to resume heating, the method further comprises the following steps: and controlling the fan to be started again.

Here, before washing unit washed the filter screen, the control fan was closed, can effectively avoid washing unit's rivers to be inhaled to the drying tunnel in by the fan, and then reduces the electrical part in the drying tunnel because of impaired risk such as soaking. In addition, before the heating device resumes heating, with the fan restart to can protect the peripheral structure of heating device, avoid the damage such as structure overheat.

In some embodiments, controlling a washing device of a laundry treating apparatus to wash a filter net includes:

controlling a washing device to continuously wash the filter screen for a first set time; alternatively, the first and second electrodes may be,

Here, the flushing device may flush the screen continuously or intermittently, for example, the on-off valve is opened for 4 seconds, i.e., the first set time period is 4 seconds; or the switch valve washes the filter screen according to the beat that the switch valve is opened for 1 second and stopped for 5 seconds, and repeats 4 beats, namely the second set time is 24 seconds. It should be noted that the above control of the flushing device is only an example, and the beat and/or duration of flushing the filter screen by the flushing device can be reasonably adjusted according to the structure of the filter screen, the structure of the drying tunnel, the rotating speed of the inner cylinder, and the like.

In some embodiments, before controlling the inner barrel to rotate in the first rotational speed mode, the method further comprises:

acquiring a detection signal representing the fluctuation of the rotating speed of the inner cylinder;

comparing the detection signal with a set unbalance amount;

and if the fluctuation of the rotating speed is less than the set unbalance amount, controlling the inner cylinder to rotate in a first rotating speed mode.

It can be understood that, because the rotating speed Of the inner barrel is increased compared with the rotating speed Of the conventional drying in the first rotating speed mode, the OOB (Out-Of-Balance) detection can be firstly carried Out on the inner barrel, and the inner barrel is controlled to rotate in the first rotating speed mode after the inner barrel meets the OOB requirement, so that dangerous working conditions such as barrel collision in the drying operation process are effectively avoided. Here, a detection signal indicative of the rotation speed fluctuation may be acquired based on the rotation speed sensor, for example, a detection signal corresponding to the rotation speed fluctuation of the inner drum for a set period of time operating at a specified rotation speed may be acquired and compared with the set unbalance amount, and if the rotation speed fluctuation is smaller than the set unbalance amount, the inner drum may be controlled to rotate in the first rotation speed mode.

Illustratively, if the rotation speed fluctuation is larger than or equal to the set unbalance amount, the control of the inner drum to rotate in the first rotation speed mode and the control of the washing device of the clothes treatment equipment to wash the filter screen are skipped, and the control of the inner drum to rotate in the second rotation speed mode and the control of the heating device to recover heating are executed. Therefore, the danger of barrel collision and the like caused by switching the inner barrel to the first rotating speed mode can be avoided based on the advanced OOB detection. For example, in the second rotation speed mode, the operating rotation speed of the inner cylinder may range from 40 to 60 revolutions per minute (rpm).

In some embodiments, as shown in fig. 4, the control method of the laundry treating apparatus further includes:

and step 304, controlling the inner barrel to rotate in a second rotating speed mode and controlling the heating device to recover heating.

It can be understood that, in the process of washing the filter screen by the washing device, the inner cylinder rotates in the first rotating speed mode, after the washing duration of the washing device reaches the set duration, the current washing is finished, the heating device resumes heating, and the inner cylinder rotates in the second rotating speed mode. It should be noted that, if the washing device washes the filter screen, the fan is in the off state, and before the heating device recovers heating, the fan needs to be turned on again, so that the peripheral structural members of the heating device can be protected, and damage such as overheating of the structural members can be avoided.

And 305, repeatedly executing the steps of controlling the heating device to stop heating, controlling the inner drum of the clothes treatment equipment to rotate in the first rotating speed mode, controlling the washing device of the clothes treatment equipment to wash the filter screen, controlling the inner drum to rotate in the second rotating speed mode and controlling the heating device to recover heating based on the obtained temperature value until the clothes treatment equipment exits the drying stage.

It can be understood that the laundry treating apparatus repeatedly performs the aforementioned steps 302 to 304 based on the acquired temperature value until exiting the drying stage. The exiting of the drying stage may be determined based on a set operation time period or based on whether the laundry meets a set drying condition, which is not particularly limited herein.

The clothes treatment equipment of the embodiment of the application is based on the control method, the water flow of the washing device for washing the filter screen can be utilized to realize condensation of air to be fed into the drying tunnel in the drying stage, so that the washing device has the dual functions of washing the filter screen and carrying out water condensation on the air, the structure for washing the filter screen is not required to be independently arranged, the water supply device is shared with the water condensation, the manufacturing cost of the clothes treatment equipment is saved, and the purpose of saving the structural cost can be achieved based on the improvement of the program.

pre-drying and hot dewatering the clothes in the inner drum;

It can be understood that, before the clothes in the inner drum is dried by the clothes treating apparatus, the clothes in the inner drum can be pre-dried and thermally dehydrated. For example, in the pre-drying stage, the fan is turned on, the motor is controlled to drive the inner cylinder to operate in the second rotation speed mode, the heating device is started to heat, the temperature value detected by the temperature sensor at the drying tunnel 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 recovers to heat, wherein T1> T2. In the pre-drying stage, the temperature in the inner barrel is increased, so that the dehydration efficiency is improved in the thermal dehydration stage.

The following applies to the present application in conjunction with the examples of applications as will be described in further detail.

In this application example, as shown in fig. 5, the method for controlling the laundry processing apparatus in the drying stage includes:

step 401, the fan and the heating device are turned on.

After the clothes treatment equipment enters a drying stage, the fan and the heating device are started, so that the fan and the heating device are both in an operating state. For example, the laundry treating apparatus may further control the drum to operate in the aforementioned second rotation speed mode.

Step 402, judging whether the temperature value of the drying tunnel is greater than 100 ℃, if not, returning to the step 401, and continuously maintaining the running states of the fan and the heating device; if yes, go to step 403.

Here, the temperature value of the drying tunnel is detected by a temperature sensor provided at the drying tunnel, and is determined based on the temperature value detected by the temperature sensor, if the temperature value is greater than 100 ℃ (i.e., the first set temperature value), the heating device needs to be turned off, otherwise, the heating state of the heating device is continuously maintained.

At step 403, the heating device is turned off.

Step 404, determining whether the temperature value of the drying tunnel is less than 95 ℃ (i.e. the second set temperature value), if not, returning to step 403, and continuing to maintain the closing state of the heating device; if yes, go to step 405.

Step 405, oob detection.

Here, a detection signal corresponding to a rotation speed fluctuation in which the inner drum is operated at a specified rotation speed for a set period of time, for example, a detection signal corresponding to a rotation speed fluctuation in which the inner drum is operated for 15 seconds, may be acquired.

Step 406, determining whether the rotation speed fluctuation meets the OOB requirement, if yes, executing step 407; if not, go to step 411.

Step 407, controlling the inner barrel to operate in the first rotation speed mode.

If the inner cylinder meets the OOB requirement, namely the rotation speed fluctuation is smaller than the set unbalance amount, the fan is turned off, and the inner cylinder is controlled to operate in the first rotation speed mode. For example, in the first rotation speed mode, the inner barrel can be alternately rotated forward and backward, for example, based on the rotation speed of 200rpm, the inner barrel can be operated for 20 seconds and pause for 5 seconds, and the inner barrel can be alternately rotated forward and backward.

Step 408, judging whether the rotating speed of the inner cylinder is greater than the set rotating speed, if so, executing step 409; if not, the operation of step 407 is maintained.

And step 409, turning off the fan and controlling the washing device to wash the filter screen.

It can be understood that, before the laundry processing apparatus controls the washing device to wash the filter screen, it may also be determined whether the rotation speed of the inner drum reaches the set rotation speed, and if it is determined that the rotation speed of the inner drum is greater than or equal to the set rotation speed, the washing device is controlled to wash the filter screen, for example, the switch valve is controlled to be turned on, so that the water flow washes the filter screen. It should be noted that, when the washing device washes the filter screen, the fan can be turned off, so as to prevent the water flow of the washing device from being sucked into the drying tunnel by the fan. For example, when the rotation speed of the inner barrel is determined to be greater than 195rpm and the rotation direction of the inner barrel is determined to be in the counterclockwise direction, the flushing device is controlled to flush the filter screen, and at this time, moist hot air discharged from the inner barrel can be better condensed by water flow after the filter screen is flushed, so that the water condensation effect is enhanced. The washing device can finish washing after continuously washing the filter screen for t1 seconds, and correspondingly, the fan synchronously stops for t1 seconds. the value of t1 can be determined experimentally, for example t1=4.

Step 410, controlling the fan to be started again;

here, after the flushing device finishes flushing, the blower may be controlled to be turned back on.

And 411, controlling the inner barrel to operate in a second rotating speed mode.

For example, in the second rotation mode, the inner cylinder can be alternately rotated forward and backward, for example, based on a rotation speed of 46rpm for 20 seconds and a beat of 5 seconds.

And step 412, controlling the heating device to be started, and returning to the step 402.

For example, the heating device may be controlled to be turned on after the blower is turned on again for a set time period in step 410, so that the heating of the heating device may be resumed after the blower is stably operated.
