Detailed Description
It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
The invention provides an air conditioner and a cleaning control method thereof, wherein when the accumulated running time of the air conditioner meets the preset time, if a refrigerating/dehumidifying instruction is received, the continuous running time of the air conditioner for pumping condensed water into a dust collecting box is determined according to the indoor environment temperature and the indoor environment humidity in the running process of the air conditioner. Like this, confirm the time of drawing water of air conditioner according to the humiture, can avoid unnecessary drawing water to reduce the clean time of filter screen, and then improve user experience.
Referring to fig. 1, in an embodiment, a cleaning control method of an air conditioner includes the steps of:
step S10, acquiring the accumulated running time of the air conditioner;
in this embodiment, the accumulated operation time starts from the first start of the air conditioner, and starts to be timed when the air conditioner operates in the cooling, heating, dehumidifying or air-blowing modes, and stops to be timed when the air conditioner is turned off and records the operation time, and continues to be accumulated when the air conditioner operates in the cooling, heating, dehumidifying or air-blowing modes next time. And clearing the accumulated running time when the air conditioner finishes cleaning the filter screen. It is to be understood that, in other embodiments, the accumulated running time does not need to be cleared, but may be accumulated all the time, and may be set reasonably according to actual needs, which is not limited in this invention.
Step S20, if the accumulated running time meets the preset time, when a refrigeration/dehumidification instruction is received, acquiring the indoor environment temperature and the indoor environment humidity in the running process of the air conditioner;
in this embodiment, the preset time may be set to 60h, and certainly, in other embodiments, other values may also be set, which is not specifically limited by the present invention.
When the accumulated running time of the air conditioner meets the preset time, if a refrigeration/dehumidification instruction is received, the air conditioner can start to generate condensed water. Further acquire the indoor ambient temperature and the indoor ambient humidity of air conditioner operation in-process, judge whether indoor ambient temperature and indoor ambient humidity satisfy the preset condition, when indoor ambient temperature and/or indoor ambient humidity reach predetermined threshold value scope, show that the air conditioner refrigerates or the comdenstion water that produces when dehumidifying can carry out the washing automatically cleaning to the filter screen, consequently, can control the air conditioner this moment and will operate the comdenstion water suction dust collecting box that refrigerates/dehumidify in-process produced to wash the dust collecting box. The air conditioner generates condensed water in a refrigeration/dehumidification mode and simultaneously pumps the generated condensed water into the dust collecting box.
Of course, in other embodiments, the two parameters of the indoor ambient temperature and the indoor ambient humidity are not limited, and may also be controlled by other manners, which is not limited in the present invention.
It will be appreciated that since there is a process of washing the dust box to discharge the waste water, the condensed water can be drawn into the dust box again or multiple times to ensure the cleanliness of the roll brush.
And step S30, when the indoor environment temperature and the indoor environment humidity meet preset conditions, controlling the air conditioner to pump condensed water generated in the operation refrigeration/dehumidification process into the dust collection box, and continuously operating until the operation time corresponding to the preset conditions is reached so as to carry out washing self-cleaning on the air conditioner.
In this embodiment, because the air conditioner generates different amounts of condensed water under different temperature and humidity conditions, when the indoor environment temperature is constant, the larger the indoor environment humidity is, the more the amount of condensed water is generated; when the indoor environment humidity is constant, the larger the indoor environment temperature is, the more the amount of the condensate water is generated. Therefore, when both the indoor ambient temperature and the indoor ambient humidity are larger, the more amount of condensed water is generated. Thus, when the amount of the generated condensed water is more, the time for pumping the condensed water into the dust collecting box is shorter; on the contrary, when the amount of the generated condensed water is smaller, the time for pumping the condensed water into the dust box is longer.
Specifically, a plurality of conditions may be preset, and each condition has a corresponding pumping operation time. Wherein, every condition includes the range interval that the indoor ambient temperature satisfies and the range interval that indoor ambient humidity satisfies, as follows:
the temperature of 22 ℃ and T is more than or equal to 18 ℃, the humidity is more than or equal to 80%, and water is pumped by a water pump for 8 min; the temperature of 25 ℃ is more than T and more than or equal to 22 ℃, the humidity is more than or equal to 80%, and a water pump pumps water for 5 min; t is more than or equal to 25 ℃ at 28 ℃, 70% is more than or equal to 40%, and water is pumped by a water pump for 15 min; the temperature T is more than or equal to 25 ℃ at 28 ℃, the humidity is more than or equal to 70%, and the water is pumped by a water pump for 8 min; t is more than or equal to 28 ℃, 70% moisture is more than or equal to 40%, and water is pumped by a water pump for 10 min; t is more than or equal to 28 ℃, the humidity is more than or equal to 70 percent, and the water is pumped by a water pump for 5 min.
In the preferred embodiment, in the preset condition, the indoor ambient temperature is greater than or equal to a first temperature threshold, such as 25 ℃, and the indoor ambient humidity is greater than or equal to a first humidity threshold 40%; or the indoor environment temperature is greater than or equal to a second temperature threshold value of 18 ℃, and the indoor environment humidity is greater than or equal to a second humidity threshold value of 80%; wherein the first temperature threshold is greater than the second temperature threshold, and the first humidity threshold is less than the second humidity threshold.
In the embodiment, when the indoor environment temperature and the indoor environment humidity are both high, the condensed water is pumped into the dust collecting box only by controlling the water pump within a short time because the amount of the generated condensed water is high; when the indoor environment temperature and the indoor environment humidity are both low, the amount of the generated condensed water is small, so that the same amount of the condensed water can be pumped into the dust collecting box only by relatively long water pumping time. Like this, current air conditioner is with the fixed time suction dust collection box with the comdenstion water, then can lead to unnecessary under the sufficient condition of comdenstion water to draw water, leads to the comdenstion water in the dust collection box to spill over even to increased the filter screen clean time of air conditioner, and then reduced user experience. The invention can accurately determine the condensed water quantity according to the actual real-time indoor environment temperature and the indoor environment humidity so as to adjust the corresponding water pumping time, thereby reducing unnecessary water pumping.
The cleaning control method of the air conditioner provided by the invention comprises the steps of obtaining the accumulated running time of the air conditioner; if the accumulated running time meets the preset time, acquiring the indoor environment temperature and the indoor environment humidity in the running process of the air conditioner when a refrigeration/dehumidification instruction is received; and when the indoor environment temperature and the indoor environment humidity meet preset conditions, controlling the air conditioner to pump condensed water generated in the operation refrigeration/dehumidification process into the dust collecting box, and continuously operating until the operation time corresponding to the preset conditions is reached so as to carry out water washing self-cleaning on the air conditioner. Like this, confirm the time of drawing water of air conditioner according to the humiture, can avoid unnecessary drawing water to reduce the clean time of filter screen, and then improve user experience.
In an embodiment, as shown in fig. 2, on the basis of the above fig. 1, the step S20 includes:
step S201, if the accumulated running time meets the preset time, performing dry brush cleaning when a shutdown instruction is received;
in this embodiment, when the accumulated operation time of the air conditioner satisfies the preset time, the filter screen is subjected to dry brushing once before the water washing self-cleaning is performed, and it can be understood that the number of times of dry brushing can be reasonably set according to actual needs. This is relatively true for air conditioners where dry brushing has never been performed before, and therefore there is little dust in the dust box, and therefore it is necessary to dry brush once and then clean the dust box. When the air conditioner cleans the filter screen next time, the air conditioner can dry and then wash the filter screen, so that the residues on the filter screen can be thoroughly removed.
Step S202, when the air conditioner completes dry brush cleaning, the indoor environment temperature and the indoor environment humidity in the running process of the air conditioner are obtained when a refrigeration/dehumidification instruction is received.
In this embodiment, when the air conditioner completes the dry-brushing cleaning, it is indicated that the air conditioner may start to generate condensed water when receiving the refrigeration/dehumidification command. At this moment, can further acquire the indoor ambient temperature and the indoor ambient humidity of air conditioner operation in-process, judge whether indoor ambient temperature and indoor ambient humidity satisfy the preset condition, if, then indicate that the comdenstion water that produces when the air conditioner refrigerates or dehumidifies is enough to carry out the washing automatically cleaning to the filter screen, also washs dust collection box and washing filter screen promptly.
In an embodiment, as shown in fig. 3, on the basis of fig. 1 or fig. 2, the step S30 includes:
step S301, when the indoor environment temperature and the indoor environment humidity meet preset conditions, controlling the air conditioner to pump condensed water generated in the operation refrigeration/dehumidification process into a dust collection box, and continuously operating until the operation time corresponding to the preset conditions is reached so as to clean the dust collection box;
in this embodiment, because the air conditioner generates different amounts of condensed water under different temperature and humidity conditions, when the indoor environment temperature is constant, the larger the indoor environment humidity is, the more the amount of condensed water is generated; when the indoor environment humidity is constant, the larger the indoor environment temperature is, the more the amount of the condensate water is generated. Therefore, when both the indoor ambient temperature and the indoor ambient humidity are larger, the more amount of condensed water is generated. Thus, when the amount of the generated condensed water is more, the time for pumping the condensed water into the dust collecting box is shorter; on the contrary, when the amount of the generated condensed water is smaller, the time for pumping the condensed water into the dust box is longer.
This embodiment through set up with the time of drawing water of indoor ambient temperature and indoor ambient humidity's correspondence can prevent under the sufficient condition of comdenstion water, leads to unnecessary to draw water, and then prevents that the comdenstion water in the dust collecting box from overflowing to can reduce unnecessary and draw water, save the clean time of air conditioner.
And S302, after the air conditioner finishes cleaning the dust collecting box, controlling the air conditioner to clean the filter screen by using the condensed water in the dust collecting box.
In this embodiment, after the air conditioner finishes cleaning the dust collecting box, the filter screen is washed by water for self-cleaning. At the moment, because no dust exists in the dust collecting box, the dust in the dust collecting box can be prevented from adhering to the filter screen along with the rotation of the rotating brush, so that the aim of cleaning the filter screen of the air conditioner is fulfilled, and the cleanliness of the filter screen is ensured.
The present invention further provides an air conditioner 100, and referring to fig. 4, in an embodiment, the air conditioner 100 includes:
the acquisition module 10 is used for acquiring the accumulated running time of the air conditioner;
in this embodiment, the accumulated operation time starts from the first start of the air conditioner, and starts to be timed when the air conditioner operates in the cooling, heating, dehumidifying or air-blowing modes, and stops to be timed when the air conditioner is turned off and records the operation time, and continues to be accumulated when the air conditioner operates in the cooling, heating, dehumidifying or air-blowing modes next time. And clearing the accumulated running time when the air conditioner finishes cleaning the filter screen. It is to be understood that, in other embodiments, the accumulated running time does not need to be cleared, but may be accumulated all the time, and may be set reasonably according to actual needs, which is not limited in this invention.
The obtaining module 10 is further configured to obtain an indoor environment temperature and an indoor environment humidity during an operation process of the air conditioner when a refrigeration/dehumidification instruction is received if the accumulated operation time meets a preset time;
in this embodiment, the preset time may be set to 60h, and certainly, in other embodiments, other values may also be set, which is not specifically limited by the present invention.
When the accumulated running time of the air conditioner meets the preset time, if a refrigeration/dehumidification instruction is received, the air conditioner can start to generate condensed water. Further acquire the indoor ambient temperature and the indoor ambient humidity of air conditioner operation in-process, judge whether indoor ambient temperature and indoor ambient humidity satisfy the preset condition, when indoor ambient temperature and/or indoor ambient humidity reach predetermined threshold value scope, show that the air conditioner refrigerates or the comdenstion water that produces when dehumidifying can carry out the washing automatically cleaning to the filter screen, consequently, can control the air conditioner this moment and will operate the comdenstion water suction dust collecting box that refrigerates/dehumidify in-process produced to wash the dust collecting box. The air conditioner generates condensed water in a refrigeration/dehumidification mode and simultaneously pumps the generated condensed water into the dust collecting box.
Of course, in other embodiments, the two parameters of the indoor ambient temperature and the indoor ambient humidity are not limited, and may also be controlled by other manners, which is not limited in the present invention.
It will be appreciated that since there is a process of washing the dust box to discharge the waste water, the condensed water can be drawn into the dust box again or multiple times to ensure the cleanliness of the roll brush.
And the control module 20 is used for controlling the air conditioner to pump condensed water generated in the operation refrigeration/dehumidification process into the dust collecting box when the indoor environment temperature and the indoor environment humidity meet preset conditions, and continuously operates to reach the operation time corresponding to the preset conditions so as to carry out washing and self-cleaning on the air conditioner.
Since the air conditioner 100 generates the condensed water in the cooling/dehumidifying mode, the filter screen of the air conditioner 100 and the dust box can be cleaned using the condensed water. The method comprises the following specific steps:
referring to fig. 5 and 6, a drain pan 18 is provided under an evaporator (not shown) of the air conditioner 100 to collect condensed water falling from the evaporator. The water pan 18 is provided with a water outlet 181 communicated with the outdoor, and water in the water pan 18 can be discharged to the outdoor through the water outlet 181. A water pump (not shown) can pump the water in the water pan 18 into the dust box 313, so that the water condensed on the evaporator and falling into the water pan 18 can be fully utilized. Similarly, the water in the dust box 313 may be discharged to the outside through a drain (not shown) to facilitate replacement of the water in the dust box 313, thereby achieving the purpose of cleaning the dust box 313.
A filter screen rotating shaft is arranged above the opening of the dust collecting box 313 to drive the filter screen 22 to move and pass through the rolling brush 311 arranged in the opening of the dust collecting box 313. Since the rolling brush 311 is in rolling contact with the filter screen 22 after being wetted, the dust and other obstructions on the filter screen 22 can adhere to the rolling brush 311, so that the filter screen 22 can be cleaned, and the dust and other obstructions can be prevented from moving to other places of the air conditioner 100 to affect the normal operation of the air conditioner 100. In addition, the dust adhered to the drum brush 311 may be dissolved in the water of the dust box 313 during the rolling of the drum brush 311, and the cleaning function of the drum brush 311 is also maintained.
In this embodiment, because the air conditioner generates different amounts of condensed water under different temperature and humidity conditions, when the indoor environment temperature is constant, the larger the indoor environment humidity is, the more the amount of condensed water is generated; when the indoor environment humidity is constant, the larger the indoor environment temperature is, the more the amount of the condensate water is generated. Therefore, when both the indoor ambient temperature and the indoor ambient humidity are larger, the more amount of condensed water is generated. Thus, when the amount of the generated condensed water is more, the time for pumping the condensed water into the dust collecting box is shorter; on the contrary, when the amount of the generated condensed water is smaller, the time for pumping the condensed water into the dust box is longer.
In a preferred embodiment, referring to fig. 7, the air conditioner further includes a setting module 30, by which a plurality of conditions can be preset, and each condition has a corresponding pumping operation time. Wherein, every condition includes the range interval that the indoor ambient temperature satisfies and the range interval that indoor ambient humidity satisfies, as follows:
the temperature of 22 ℃ and T is more than or equal to 18 ℃, the humidity is more than or equal to 80%, and water is pumped by a water pump for 8 min; the temperature of 25 ℃ is more than T and more than or equal to 22 ℃, the humidity is more than or equal to 80%, and a water pump pumps water for 5 min; t is more than or equal to 25 ℃ at 28 ℃, 70% is more than or equal to 40%, and water is pumped by a water pump for 15 min; the temperature T is more than or equal to 25 ℃ at 28 ℃, the humidity is more than or equal to 70%, and the water is pumped by a water pump for 8 min; t is more than or equal to 28 ℃, 70% moisture is more than or equal to 40%, and water is pumped by a water pump for 10 min; t is more than or equal to 28 ℃, the humidity is more than or equal to 70 percent, and the water is pumped by a water pump for 5 min.
In the preferred embodiment, in the preset condition, the indoor ambient temperature is greater than or equal to a first temperature threshold, such as 25 ℃, and the indoor ambient humidity is greater than or equal to a first humidity threshold 40%; or the indoor environment temperature is greater than or equal to a second temperature threshold value of 18 ℃, and the indoor environment humidity is greater than or equal to a second humidity threshold value of 80%; wherein the first temperature threshold is greater than the second temperature threshold, and the first humidity threshold is less than the second humidity threshold.
In the embodiment, when the indoor environment temperature and the indoor environment humidity are both high, the condensed water is pumped into the dust collecting box only by controlling the water pump within a short time because the amount of the generated condensed water is high; when the indoor environment temperature and the indoor environment humidity are both low, the amount of the generated condensed water is small, so that the same amount of the condensed water can be pumped into the dust collecting box only by relatively long water pumping time. Like this, current air conditioner is with the fixed time suction dust collection box with the comdenstion water, then can lead to unnecessary under the sufficient condition of comdenstion water to draw water, leads to the comdenstion water in the dust collection box to spill over even to increased the filter screen clean time of air conditioner, and then reduced user experience. The invention can accurately determine the condensed water quantity according to the actual real-time indoor environment temperature and the indoor environment humidity so as to adjust the corresponding water pumping time, thereby reducing unnecessary water pumping.
The air conditioner provided by the invention obtains the accumulated running time of the air conditioner; if the accumulated running time meets the preset time, acquiring the indoor environment temperature and the indoor environment humidity in the running process of the air conditioner when a refrigeration/dehumidification instruction is received; and when the indoor environment temperature and the indoor environment humidity meet preset conditions, controlling the air conditioner to pump condensed water generated in the operation refrigeration/dehumidification process into the dust collecting box, and continuously operating until the operation time corresponding to the preset conditions is reached so as to carry out water washing self-cleaning on the air conditioner. Like this, confirm the time of drawing water of air conditioner according to the humiture, can avoid unnecessary drawing water to reduce the clean time of filter screen, and then improve user experience.
In an embodiment, as shown in fig. 8, on the basis of fig. 4 or fig. 7, the obtaining module 10 includes:
the processing unit 101 is configured to perform dry brush cleaning when a shutdown instruction is received if the accumulated running time meets a preset time;
in this embodiment, when the accumulated operation time of the air conditioner satisfies the preset time, the filter screen is subjected to dry brushing once before the water washing self-cleaning is performed, and it can be understood that the number of times of dry brushing can be reasonably set according to actual needs. This is relatively true for air conditioners where dry brushing has never been performed before, and therefore there is little dust in the dust box, and therefore it is necessary to dry brush once and then clean the dust box. When the air conditioner cleans the filter screen next time, the air conditioner can dry and then wash the filter screen, so that the residues on the filter screen can be thoroughly removed.
The obtaining unit 102 is configured to obtain an indoor environment temperature and an indoor environment humidity during an operation process of the air conditioner when a cooling/dehumidifying instruction is received after the air conditioner completes dry brush cleaning.
In this embodiment, when the air conditioner completes the dry-brushing cleaning, it is indicated that the air conditioner may start to generate condensed water when receiving the refrigeration/dehumidification command. At this moment, can further acquire the indoor ambient temperature and the indoor ambient humidity of air conditioner operation in-process, judge whether indoor ambient temperature and indoor ambient humidity satisfy the preset condition, if, then indicate that the comdenstion water that produces when the air conditioner refrigerates or dehumidifies is enough to carry out the washing automatically cleaning to the filter screen, also washs dust collection box and washing filter screen promptly.
In an embodiment, as shown in fig. 9, based on the above fig. 4 or fig. 7, the control module 20 includes:
the water pumping control unit 201 is used for controlling the air conditioner to pump condensed water generated in the operation refrigeration/dehumidification process into the dust collection box when the indoor environment temperature and the indoor environment humidity meet preset conditions, and continuously operates until the operation time corresponding to the preset conditions is reached so as to clean the dust collection box;
in this embodiment, because the air conditioner generates different amounts of condensed water under different temperature and humidity conditions, when the indoor environment temperature is constant, the larger the indoor environment humidity is, the more the amount of condensed water is generated; when the indoor environment humidity is constant, the larger the indoor environment temperature is, the more the amount of the condensate water is generated. Therefore, when both the indoor ambient temperature and the indoor ambient humidity are larger, the more amount of condensed water is generated. Thus, when the amount of the generated condensed water is more, the time for pumping the condensed water into the dust collecting box is shorter; on the contrary, when the amount of the generated condensed water is smaller, the time for pumping the condensed water into the dust box is longer.
This implementation through set up with the time of drawing water of indoor ambient temperature and indoor ambient humidity's correspondence can prevent under the sufficient condition of comdenstion water, leads to unnecessary to draw water, and then prevents that the comdenstion water in the dust-collecting box from spilling over to can reduce unnecessary and draw water, save the clean time of air conditioner.
And the cleaning control unit 202 is used for controlling the air conditioner to clean the filter screen by using the condensed water in the dust collecting box after the air conditioner finishes cleaning the dust collecting box.
In this embodiment, after the air conditioner finishes cleaning the dust collecting box, the filter screen is washed by water for self-cleaning. At the moment, because no dust exists in the dust collecting box, the dust in the dust collecting box can be prevented from adhering to the filter screen along with the rotation of the rotating brush, so that the aim of cleaning the filter screen of the air conditioner is fulfilled, and the cleanliness of the filter screen is ensured.
The above description is only a preferred embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications of equivalent structures and equivalent processes, which are made by using the contents of the present specification and the accompanying drawings, or directly or indirectly applied to other related technical fields, are included in the scope of the present invention.
