All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present invention without making any inventive efforts all fall within the extent of protection of the present invention.
As shown in Fig. 1, the present embodiment provides a control method for a laundry machine, comprising: step S101: receiving an instruction of cleaning a filtering assembly, in which: the manner of inputting the instruction of cleaning the filtering assembly is not limited, e.g., the instruction of cleaning the filtering assembly may be input via an operation panel or display panel of the laundry machine, or the instructionto clean the filtering assembly is input into the laundry machine via the Internet of Things; and step S102: controlling washing liquid to enter the filtering assembly.
The present invention does not limit a controlling and processing manner of a laundry machine in the absence of input of the instruction of cleaning the filtering assembly, for example, an optional embodiment: entering a conventional laundry process.
According to the technical solution provided by the present embodiment, after the instruction of cleaning the filtering assembly is received, a procedure of cleaning the filtering assembly is performed to control a washing liquid to enter the filtering assembly to clean the filtering assembly. Therefore, the technical solution provided by the present invention can controllably perform cleaning maintenance on the filtering assembly, and clean the dirt intercepted by the filter membrane(s) of the filtering assembly in time, so as to avoid the difficulty of cleaning the filtering assembly due to the long-term residue of the dirt, which facilitates extending the service life of the filtering assembly, reduce the maintenance costs of the laundry machine and ensures reliable operation of the filtering assembly.
The washing liquid in the embodiment of the present invention is a mixed -5- solution of detergent (or named as abstergent) and water.
Particularly, the cleaning procedure further comprises: turning on a pipeline between a washing cylinder and the filtering assembly of the laundry machine to introduce the washing liquid through the pipeline from the washing cylinder to the filtering assembly. The introduced washing liquid will stay in the filtering assembly for its preset duration, i.e., immerse the filtering assembly for its preset duration.
As an optional embodiment, the filtering assembly is subjected to air-purging at least once during the preset duration while the introduced washing liquid stays in the filtering assembly.
The washing liquid, after being introduced into the filtering assembly, stays for its preset duration to immerse the filtering assembly, and the preset duration for immersing the filtering assembly is preferably 2-5 minutes. During this period of time, corresponding valve and air pump are opened to perform air-purging of the filtering assembly at least once for its preset duration. The preset duration of air-purging the filtering assembly is preferably 1-3 minutes. The washing liquid in the filtering assembly is discharged out of the laundry machine after completion of the air-purging.
The filtering assembly is first immersed so that a part of the dirt on the filtering assembly falls off into the washing liquid in the filtering assembly, then air-purging is performed to further cause the dirt remaining on the filtering assembly to fall off, and the washing liquid in the filtering assembly is discharged out of the laundry machine after completion of the air-purging. At this time, the filtering assembly may reach certain cleanness to ensure reliable operation of the filtering assembly in subsequent clothes-washing procedure and clothes-rinsing procedure.
As an optional embodiment, before turning on the pipeline between the washing cylinder and the filtering assembly of the laundry machine, the cleaning procedure further comprises heating the washing liquid in the washing cylinder to its preset temperature. -6-
The preset temperature is preferably 30-60 degrees centigrade. At this temperature, activity of the detergent in the washing liquid can be maximized to further improve the cleaning capability of the detergent and thereby further improve the cleanness of the filtering assembly.
As an optional embodiment, after the instruction of cleaning the filtering assembly is received, the washing liquid is controlled to enter the filtering assembly for cleaning in a laundry process.
Generally, the laundry process comprises: a clothes-immersing procedure, a clothes-washing procedure, a clothes-rinsing procedure and a clothes-dewatering procedure. As a preferred embodiment, if the instruction of cleaning the filtering assembly is received, the washing liquid is controlled in the clothes-immersing procedure or the clothes-washing procedure to enter the filtering assembly for cleaning it.
Since the clothes-immersing procedure and the clothes-washing procedure are prior to the clothes-rinsing procedure, the cleaning of the filtering assembly in the clothes-immersing procedure or the clothes-washing procedure can ensure reliable operation of the filtering assembly in subsequent clothes-rinsing procedure.
As an optional embodiment, the control method for the laundry machine according to the present invention further comprises: accumulating the number of times of the laundry machine performing the laundry process, namely, accumulating the number of times of laundry.
Detecting whether to generate the instruction of cleaning the filtering assembly comprises detecting whether the number of times of laundry reaches its preset threshold, and generating the instruction of cleaning the filtering assembly if yes.
In the laundry machine and the control method thereof according to the present invention, those skilled in the art may appreciate that when the instruction of cleaning the filtering assembly is generated, a corresponding module of the device and a corresponding step of the method will also receive the instruction of -7- cleaning the filtering assembly.
When the number of times of laundry reaches its preset threshold, the instruction of cleaning the filtering assembly is generated, and the washing liquid is controlled to enter the filtering assembly for cleaning, i.e., the filtering assembly is automatically cleaned after the filtering assembly is used for a certain period of time, which improves the intelligence degree of control of the laundry machine.
As an optional embodiment, the control method for the laundry machine according to the present embodiment also comprises: detecting a pressure value (i.e., differential pressure) between both ends of the filtering assembly, and generating the instruction of cleaning the filtering assembly if the pressure value reaches its preset threshold.
Particularly, a pressure sensor is configured to detect a pressure value (i.e., differential pressure) between a water inlet end and a water outlet end of the filtering assembly. If the pressure value reaches its preset threshold, this indicates that dirt-plugging is caused in the interior of the filtering assembly, and at this moment the instruction of cleaning the filtering assembly is generated, and the washing liquid is controlled to enter the filtering assembly for cleaning.
Whether dirt-plugging occurs in the filtering assembly may be determined by detecting the pressure value between both ends of the filtering assembly. Cleanness of the filtering assembly is effectively maintained and reliable operation of the filtering assembly is ensured by cleaning the filtering assembly in time when dirt-plugging occurs in the filtering assembly.
Fig. 2 is a block diagram showing a principle of a laundry machine according to the present invention. As shown in Fig. 2, the laundry machine according to the present embodiment comprises a washing cylinder 301, a filtering assembly 303, a control device 302 and a pipeline 304 communicating the washing cylinder 301 with the filtering assembly 303. The control device 302 is configured to receive an instruction of cleaning the filtering assembly, and control delivery of the washing liquid in the washing cylinder 301 to the filtering -8- assembly 303 through the pipeline 304 after reception of instruction of cleaning the filtering assembly.
In the technical solution provided by the present embodiment, after detecting that there is input of the instruction of cleaning the filtering assembly, the control device 302 controls the washing liquid to enter the filtering assembly 303 for cleaning. Hence, the technical solution according to the present invention controllably cleans and maintains the filtering assembly to ensure reliable operation of the filtering assembly.
The washing liquid in the embodiment of the present invention is a mixed solution of detergent and water.
Particularly, the control device 302 controls turn-on of the pipeline 304 between the washing cylinder 301 and the filtering assembly 303 of the laundry machine, so as to introduce the washing liquid through the pipeline 304 to the filtering assembly 303, which introduced washing liquid is discharged out after immersing for its preset duration.
As an optional embodiment, the control device 302 is also configured to control the introduced washing liquid to perform air-purging of the filtering assembly 303 at least once during the preset duration while the introduced washing liquid stays in the filtering assembly 303.
The washing liquid, after being introduced into the filtering assembly 303, stays for a preset duration to immerse the filtering assembly 303, and the preset duration for immersing the filtering assembly is preferably 2-5 minutes. During the preset duration for immersing the filtering assembly, corresponding valve(s) and air pump are opened to perform air-purging of the filtering assembly 303 at least once for a preset duration. The preset duration of air-purging the filtering assembly is preferably 1-3 minutes. The introduced washing liquid is discharged out of the laundry machine after completion of the air-purging.
The filtering assembly 303 is first immersed so that a part of the dirt on the filtering assembly 303 falls off into the washing liquid in the filtering assembly, then air-purging is performed to further cause the dirt remaining on the filtering -9- assembly 303 to fall off, and the washing liquid in the filtering assembly is discharged out of the laundry machine after completion of the air-purging. At this time, the filtering assembly 303 may reach certain cleanness to ensure reliable operation of the filtering assembly 303 in subsequent clothes-washing 5 procedure and clothes-rinsing procedure. 2014295691 31 Mar 2017
In addition, it is feasible to again introduce a suitable amount of washing liquid from the washing cylinder 301 to clean the filtering assembly.
As an optional embodiment, the control device 302 is also configured to control heating the washing liquid in the washing cylinder 301 to a preset ίο temperature.
The preset temperature is preferably 30-60 degrees centigrade. At this temperature, activity of the detergent in the washing liquid may be maximized to further improve the cleaning capability of the detergent and thereby further improve the cleanness of the filtering assembly. 15 As an optional embodiment, the control device 302 is also configured to, after receiving the instruction of cleaning the filtering assembly, control the washing liquid to enter the filtering assembly 303 for cleaning in the laundry process of the laundry machine.
Generally, the laundry process comprises: a clothes-immersing procedure, a 20 clothes-washing procedure, a clothes-rinsing procedure and a clothes-dewatering procedure. As a preferred embodiment, if the instruction of cleaning the filtering assembly is received, the control device 302 controls the washing liquid to enter the filtering assembly 303 for cleaning in the clothes-immersing procedure or the clothes-washing procedure. 25 Since the clothes-immersing procedure and the clothes-washing procedure are prior to the clothes-rinsing procedure, the filtering assembly is cleaned in the clothes-immersing procedure or the clothes-washing procedure to ensure reliable operation of the filtering assembly in subsequent clothes-rinsing procedure.
As an optional embodiment, the control device 302 of the laundry machine 30 according to the present invention is also configured to accumulate the number of -10- times of laundry and detect whether the number of times of laundry reaches a preset threshold, and generate the instruction of cleaning the filtering assembly if yes. 2014295691 31 Mar 2017
When the number of times of laundry reaches its preset threshold, the 5 instruction of cleaning the filtering assembly is generated, the washing liquid is controlled to enter the filtering assembly 303 for cleaning, i.e., the cleaning procedure of the filtering assembly is automatically performed after the filtering assembly is used for a certain period of time to improve the intelligence degree of control of the laundry machine. 10 As an optional embodiment, the control device 302 according to the present embodiment is also configured to control detecting a pressure value (i.e., differential pressure) between both ends of the filtering assembly 303, and generate the instruction of cleaning the filtering assembly if the pressure value reaches a preset threshold. 15 Particularly, the control device 302 controls a pressure sensor to detect a pressure value (i.e., differential pressure) between a water inlet end and a water outlet end of the filtering assembly 303. If the pressure value reaches its preset threshold, this indicates that dirt-plugging is already caused in the interior of the filtering assembly 303, whereupon the instruction of cleaning the filtering 20 assembly 303 is generated, and the cleaning procedure is performed to clean the filtering assembly 303.
Whether dirt-plugging occurs in the filtering assembly may be determined by detecting the pressure value between both ends of the filtering assembly. Cleanness of the filtering assembly is effectively maintained and reliable 25 operation of the filtering assembly is ensured by cleaning the filtering assembly in time when dirt-plugging occurs in the filtering assembly.
Fig. 3 is taken as an example to exemplarily illustrate the laundry process which may be formed according to the technical solution provided by the present invention. The laundry machine according to the embodiment of the present 30 invention comprises a control device. Besides, as shown in Fig. 3, the laundry - it - machine further comprises a detergent box, a first valve 1, a turbidity sensor 2, a washing cylinder 3, a water pump 4, a first three-way valve 5, a second valve 6, a water discharge port 7, a coarse filter 8, a filtering assembly 9, a check valve 10, an air pump 11, a second three-way valve 12, a pipeline 13 and a heating device 14.
Clean water enters the detergent box through the first valve 1 to wash the detergent in the detergent box into the washing cylinder 3 to form the washing liquid.
After completion of water ingress, the laundry process enters to the clothes-immersing procedure, and at this time the control device detects whether there is input of the instruction of cleaning the filtering assembly; if yes, the pipeline 13 between the washing cylinder 3 and the filtering assembly 9 is turned on to introduce the washing liquid into the filtering assembly 9. The water pump 4, the coarse filter 8 and the second valve 6 are provided in the pipeline 13. During the immersing procedure, the three-way valve 5 is opened so that the water discharge pipeline is communicated, and the air pump 11 and the check valve 10 are opened so that air flow passes through the check valve 10 to air purge the filtering assembly 9 and the washing liquid in the filtering assembly 9 is discharged to the water discharge port 7 after completion of the air-purging.
As an optional embodiment, before the pipeline 13 is turned on, the heating device 14 heats the washing liquid in the washing cylinder 3 to its preset temperature, which heating device 14 comprises a temperature sensor for detecting the temperature of the washing liquid; then the second valve 6 is opened so that partial washing liquid in the washing cylinder 3 passes through the water pump 4, the filter 8 and the second valve 6 into the filtering assembly 9 for immersion.
After completion of the cleaning of the filtering assembly 9, the laundry process enters to the clothes-washing procedure. After the clothes are washed for a preset duration, the turbidity sensor 2 detects turbidity of the washing liquid in the washing cylinder 3. If the detected turbidity value is smaller than a preset -12- threshold, the water pump 4, the second valve 6 and the second three-way valve 12 are turned on to communicate to the washing cylinder 3 of the laundry machine so that the washing liquid enters through the water pump 4 into the coarse filter 8 for coarse filtering, and then enters through the second valve 6 into 5 the filtering assembly for fine filtering to achieve purification of the laundry water. The purified washing liquid flows back to the washing cylinder 3 through the second three-way valve 12 for cyclical use. If the turbidity of the washing liquid is greater than its preset threshold, the first three-way valve 5 is turned on to discharge the washing liquid out of the laundry machine, ίο In addition, the laundry machine according to the present embodiment 2014295691 31 Mar 2017 further comprises a pressure sensor (not shown in the figures) for detecting a pressure value between both ends of the filtering assembly 9. The pressure value is used to determine whether dirt-plugging occurs in the filtering assembly, and reference may be made to the embodiment regarding the control method for 15 the laundry machine for a specific procedure.
The laundry machine and the control method thereof according to the present invention can clean the dirt intercepted by a filter membrane of the filtering assembly in time, avoid the difficulty of cleaning the filtering assembly due to long-term residue of the dirt, facilitate extending the service life of the 20 filtering assembly, and reduce the maintenance costs of the laundry machine.
