Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.
A self-cleaning method and apparatus of an air conditioner, an electronic device, and a computer-readable storage medium according to embodiments of the present invention are described below with reference to the accompanying drawings.
Fig. 1 is a flowchart illustrating a self-cleaning method of an air conditioner according to an embodiment of the present invention.
As shown in fig. 1, the self-cleaning method of an air conditioner according to an embodiment of the present invention includes the following steps:
and S101, responding to a self-cleaning instruction aiming at the air conditioner, and controlling the air conditioner to enter a refrigeration and water condensation stage.
It should be noted that the air conditioner in the embodiment of the present invention has a self-cleaning function, and can respond to a self-cleaning command for itself to control itself to enter a cooling and water condensing stage. The refrigeration and condensation stage refers to a stage of causing an indoor heat exchanger in the air conditioner to generate condensed water.
It can be understood that, when the air conditioner operates in the condensation water making stage, the operation mode of the air conditioner can be a refrigeration mode or a dehumidification mode, if the temperature of the indoor coil is less than the dew point temperature, the air entering the indoor heat exchanger is liquefied when meeting the refrigeration, and condensation water can be generated on the outer surface of the indoor heat exchanger, so as to achieve the purpose of cleaning dust and dirt inside the indoor heat exchanger.
Optionally, the user may send the self-cleaning instruction to the air conditioner through a remote controller, an air conditioner APP (Application program) in the mobile terminal, or an operation panel on the body of the air conditioner in a non-contact manner such as a language, a gesture, or the like.
S102, acquiring a first water condensation time length required by the air conditioner and/or a first target temperature of an evaporator in the air conditioner.
S103, identifying that the operation time of the air conditioner in the condensate water making stage reaches a first condensate water time and/or the temperature of an indoor coil of the air conditioner is reduced to a first target temperature, and ending the refrigeration and condensate water stage.
It can be understood that, the longer the air conditioner is operated in the stage of producing condensed water, the larger the amount of air entering the indoor heat exchanger, and the more amount of condensed water generated by the indoor heat exchanger.
In an embodiment of the invention, if it is recognized that the operation time of the air conditioner in the condensate water making stage does not reach the first condensate water time, it indicates that the operation time of the air conditioner in the condensate water making stage is shorter, the amount of condensate water generated by the indoor heat exchanger is less, and the indoor heat exchanger cannot be thoroughly cleaned, and at this time, it can be determined that the refrigeration and condensate water stage is not ended, that is, the air conditioner is controlled to continue to be in the refrigeration and condensate water stage; if the operation time of the air conditioner in the condensate water making stage reaches the first condensate water time, the operation time of the air conditioner in the condensate water making stage is longer, the amount of condensate water generated by the indoor heat exchanger is larger, the indoor heat exchanger can be thoroughly cleaned, and the refrigeration and condensate water making stage can be judged to be finished.
In an embodiment of the present invention, if it is recognized that the temperature of the indoor coil of the air conditioner is not reduced to the first target temperature, it indicates that the temperature of the indoor coil is higher, that is, the degree of liquefaction of the air entering the indoor heat exchanger when meeting cold is lower, and the amount of condensed water generated by the indoor heat exchanger is less, and the indoor heat exchanger cannot be thoroughly cleaned, and at this time, it may be determined that the cooling and condensing stage is not finished, that is, the air conditioner is controlled to continue to be in the cooling and condensing stage; if the temperature of the indoor coil of the air conditioner is reduced to the first target temperature, the temperature of the indoor coil is lower at the moment, namely the degree of air entering the indoor heat exchanger to be liquefied when meeting cold is higher, the amount of condensed water generated by the indoor heat exchanger is more, the indoor heat exchanger can be thoroughly cleaned, and the refrigeration and condensation stage can be judged to be finished at the moment.
Optionally, whether the refrigeration and condensation stage is finished or not can be judged by comprehensively considering the influence of the operation time and the temperature of the indoor coil pipe on the amount of the condensation water. For example, if it is recognized that the operation time of the air conditioner in the condensation water making stage does not reach the first condensation time, or the temperature of the indoor coil of the air conditioner is not reduced to the first target temperature, the amount of condensation water generated by the indoor heat exchanger is small, the indoor heat exchanger cannot be thoroughly cleaned, and it can be judged that the condensation water making stage is not ended, that is, the air conditioner is controlled to be in the condensation water making stage continuously; if the operation time of the air conditioner in the condensate water making stage reaches the first condensate water time, and the temperature of the indoor coil of the air conditioner is reduced to the first target temperature, the amount of condensate water generated by the indoor heat exchanger is large, the indoor heat exchanger can be thoroughly cleaned, and the refrigeration condensate water making stage can be judged to be finished.
Optionally, the first water condensation time length and the first target temperature can be calibrated according to actual conditions.
Optionally, a timer is installed inside the air conditioner, and the timer is controlled to start timing when the air conditioner enters the refrigeration and condensation stage, so as to obtain the operation duration of the air conditioner in the refrigeration and condensation stage. The temperature sensor can be arranged on the wall of the indoor coil pipe of the air conditioner to acquire the temperature of the indoor coil pipe of the air conditioner.
Optionally, when the air conditioner is in a cooling and water condensing stage, the temperature of the indoor coil of the air conditioner can be reduced by adjusting the operating parameters of the air conditioner. The operating parameters of the air conditioner may include an operating frequency of the compressor, a rotational speed of the indoor fan, an opening degree of the throttling element, and the like, which are not listed here. Optionally, the throttling element may comprise an expansion valve. For example, when the air conditioner is operated in a cooling mode, if the operating frequency of the compressor is increased, and/or the rotational speed of the indoor fan is decreased, and/or the opening degree of the throttling element is decreased, the temperature of the indoor coil is decreased according to the principle of the cooling cycle.
In summary, according to the self-cleaning method of the air conditioner of the embodiment of the invention, whether the refrigeration water condensation stage of the air conditioner is finished or not can be judged according to the first water condensation duration required by the air conditioner and/or the first target temperature of the evaporator in the air conditioner, so that sufficient condensed water is generated inside the indoor heat exchanger to thoroughly clean the indoor heat exchanger, and the problems of energy waste and inconvenience to users caused by excessive amount of condensed water generated inside the indoor heat exchanger due to too long refrigeration water condensation stage of the air conditioner can be avoided.
A self-cleaning method of an air conditioner according to another embodiment of the present invention will be described with reference to fig. 2.
As shown in fig. 2, the self-cleaning method of an air conditioner according to an embodiment of the present invention includes the following steps:
s201, responding to a self-cleaning instruction aiming at the air conditioner, and controlling the air conditioner to enter a refrigeration and water condensation stage.
S202, acquiring environment information of the environment where the air conditioner is located, and acquiring first water condensation time according to the environment information, the indoor coil temperature of the air conditioner and the accumulated running time of the air conditioner.
The method can comprehensively consider the influence of environment information, the indoor coil temperature of the air conditioner and the accumulated operation time of the air conditioner on the first condensation time, and different environment information, indoor coil temperatures and accumulated operation time can correspond to different first condensation time, so that the obtained first condensation time is closer to the actual condensation requirement and is more flexible and accurate.
The environment information may include information such as an indoor temperature, an outdoor temperature, an indoor humidity, and an outdoor humidity of an environment where the air conditioner is located. Optionally, the outdoor temperature and the outdoor humidity may be obtained by respectively installing a temperature sensor and a humidity sensor on an outdoor unit of the air conditioner, or by querying weather information through a wireless network device; the indoor temperature and the indoor humidity can be obtained by respectively installing a temperature sensor and a humidity sensor on an indoor unit of the air conditioner.
The accumulated running time of the air conditioner can be obtained by installing a timer in the air conditioner.
Optionally, the first water condensation time length is obtained according to the environment information, the indoor coil temperature of the air conditioner and the accumulated operation time length of the air conditioner, and may include that a mapping relation or a mapping table between the environment information, the indoor coil temperature, the accumulated operation time length and the first water condensation time length is established in advance, and after the environment information, the indoor coil temperature and the accumulated operation time length are obtained, the mapping relation or the mapping table is inquired, so that the first water condensation time length required by the air conditioner at this time can be obtained.
In an embodiment of the present invention, the first condensed water duration may be obtained according to an indoor temperature, an indoor humidity, an indoor coil temperature, and an accumulated operation duration.
It can be understood that the longer the operation time of the air conditioner in the condensate water making stage is, the larger the air amount entering the indoor heat exchanger is, the more the condensate water amount generated by the indoor heat exchanger is, and it can be known that the first condensate water time period is positively correlated to the actually required condensate water amount. Wherein the actually required amount of condensed water is related to the accumulated operation time. The accumulated operation time can reflect the ash deposition degree of the indoor heat exchanger, and the longer the accumulated operation time is, the higher the ash deposition degree of the indoor heat exchanger is, the more the required condensate water quantity is, namely the actually required condensate water quantity is positively correlated with the accumulated operation time.
When the air conditioner is in a refrigeration and condensation stage, the actually generated condensation water quantity is positively correlated with the dew point temperature and is also negatively correlated with the temperature of the indoor coil. Wherein, the dew point temperature is positively correlated with the indoor temperature and the indoor humidity respectively, and then the actually generated condensed water quantity is positively correlated with the indoor temperature and the indoor humidity respectively.
The influence of the actually generated condensed water amount and the actually needed condensed water amount on the first condensed water duration is combined, and the first condensed water duration is respectively related to the indoor temperature, the indoor humidity, the indoor coil temperature and the accumulated running duration.
Therefore, in the process of acquiring the first condensation time, the method can comprehensively consider the influence of the indoor temperature, the indoor humidity, the indoor coil temperature and the accumulated operation time on the first condensation time, so that the acquired first condensation time is closer to the actual condensation demand, and is more flexible and accurate.
For example, according to the indoor temperature, the indoor humidity, the indoor coil temperature and the accumulated running time, the correlation formula for obtaining the first condensed water time is as follows:
S1＝S0+k1*(T1-A)-k2*(φ％-B％)+k3*(T2-C)+k4*(S2-D)
wherein S is1For the first condensation time, T1Is the indoor temperature, [ phi ] is the indoor relative humidity, T2Is the indoor coil temperature, S2For accumulating the running time, S0Is a reference value of the first water condensation time, A is a reference value of the indoor temperature, B% is a reference value of the indoor relative humidity, C is a reference value of the indoor coil temperature, D is a reference value of the accumulated running time, k1、k2、k3、k4Are all correction coefficients.

And S203, determining a first target temperature of an evaporator in the air conditioner according to the environment information of the air conditioner.
The method can consider the influence of the environmental information on the first target temperature, and different environmental information can correspond to different first target temperatures, so that the obtained first target temperature is matched with the environmental information, is closer to the actual condensation requirement, and is more flexible and accurate.
The environment information may include information such as an indoor temperature, an outdoor temperature, an indoor humidity, and an outdoor humidity of an environment where the air conditioner is located.
Optionally, determining the first target temperature according to the environment information may include pre-establishing a mapping relationship or a mapping table between the environment information and the first target temperature, and after the environment information is obtained, querying the mapping relationship or the mapping table to obtain the first target temperature required by the evaporator at that time.
In one embodiment of the present invention, the first target temperature may be obtained according to the indoor temperature and the indoor humidity.
It will be appreciated that the amount of condensate actually produced is positively correlated to the dew point temperature and also negatively correlated to the indoor coil temperature. Wherein, the dew point temperature is positively correlated with the indoor temperature and the indoor humidity respectively, and then the actually generated condensed water quantity is positively correlated with the indoor temperature and the indoor humidity respectively.
As can be seen from the above analysis, when the indoor temperature and/or the indoor humidity is/are low, the dew point temperature is low, and the condensed water generated by the indoor heat exchanger is less, so as to ensure that the indoor heat exchanger generates enough condensed water, the first target temperature of the evaporator can be reduced; when the indoor temperature and/or the indoor humidity are/is higher, the dew point temperature is higher, more condensed water is generated by the indoor heat exchanger, and the first target temperature of the evaporator can be increased in order to avoid energy waste. First target temperature is positive correlation with indoor temperature, indoor humidity respectively promptly, can ensure that the inside sufficient comdenstion water that produces of indoor heat exchanger to carry out thorough cleanness to indoor heat exchanger, still can avoid the inside comdenstion water that produces of air conditioner too much, cause the energy waste and bring inconvenient problem for the user.
For example, the correlation formula for obtaining the first target temperature according to the indoor temperature and the indoor humidity is as follows:
T3＝(T1+k5*(φ％-E％)—F)±G
wherein, T3Is a first target temperature, T1Is the indoor temperature, [ phi ] is the indoor relative humidity, [ E ] is the reference value of the indoor relative humidity, [ F ] is the corrected reference value of the first target temperature, [ G ] is the fluctuation amplitude of the first target temperature, [ k ]5Is a correction factor.
Optionally, parameter E, F, G, k5Can be calibrated according to the actual situation, for example, E can be calibrated to be 60, F can be calibrated to be 8 ℃, G can be calibrated to be 2 ℃, and k5Which may be scaled to 0.1.

In summary, according to the self-cleaning method of the air conditioner in the embodiment of the present invention, the influence of the environmental information, the temperature of the indoor coil of the air conditioner, and the accumulated operation time of the air conditioner on the first water condensation time period can be comprehensively considered, and the influence of the environmental information on the first target temperature is considered, so that the obtained first water condensation time period and the obtained first target temperature are closer to the actual condensation requirement, and are more flexible and accurate.
A self-cleaning method of an air conditioner according to another embodiment of the present invention will be described with reference to fig. 3.
As shown in fig. 3, the self-cleaning method of an air conditioner according to an embodiment of the present invention includes the following steps:
s301, responding to a self-cleaning instruction aiming at the air conditioner, and controlling the air conditioner to enter a refrigeration and water condensation stage.
S302, acquiring a first water condensation time length required by the air conditioner and/or a first target temperature of an evaporator in the air conditioner.
In an embodiment of the invention, after the first water condensation time period is obtained, the first water condensation time period may be further controlled within a preset water condensation time period range. The preset water condensation time length range refers to a reasonable operation time length range of the air conditioner in the refrigeration and water condensation stage, and can be calibrated according to actual conditions.
According to the method, the first water condensation time length is controlled within the preset water condensation time length range, so that the first water condensation time length is within a reasonable range, the problems that the obtained first water condensation time length is too short, the amount of condensed water generated by the indoor heat exchanger is too small, and cleaning is not thorough can be solved, the problems that the obtained first water condensation time length is too long, the amount of condensed water generated by the indoor heat exchanger is too large, energy is wasted, and the waiting time of a user is prolonged can be solved, the cleaning effect of the indoor heat exchanger is guaranteed, energy is saved, and the comfort level of the user is improved.
S303, identifying that the operation time of the air conditioner in the condensate water making stage reaches a first condensate water time and/or the temperature of an indoor coil of the air conditioner is reduced to a first target temperature, and ending the refrigeration and condensate water stage.
In one embodiment of the present invention, after identifying that the temperature of the indoor coil of the air conditioner is reduced to the first target temperature, the temperature of the indoor coil is further reduced to the first target temperature for a first period of time, and then the refrigeration and condensation stage is ended.
According to the method, the temperature of the indoor coil pipe is reduced to the first target temperature for the first time, so that the indoor heat exchanger has enough time to generate condensed water under the condition that the temperature of the coil pipe is reduced to the first target temperature, the amount of the condensed water generated by the indoor heat exchanger in the condensed water preparation stage is increased, and the cleaning effect of the indoor heat exchanger is enhanced.
The first time period may be calibrated according to actual conditions, for example, may be calibrated to be 15 minutes.
In one embodiment of the present invention, the first time period may be further acquired according to an accumulated operation time period of the air conditioner.
It can be understood that the longer the operation time period for keeping the temperature of the indoor coil reduced to the first target temperature is, the more the amount of condensed water generated by the indoor heat exchanger is, and it can be known that the first time period is positively correlated with the actually required amount of condensed water. Wherein the actually required amount of condensed water is related to the accumulated operation time. The accumulated operation time can reflect the ash deposition degree of the indoor heat exchanger, and the longer the accumulated operation time is, the higher the ash deposition degree of the indoor heat exchanger is, the more the required condensate water quantity is, that is, the actually required condensate water quantity is positively correlated with the accumulated operation time.
From the above analysis, it can be seen that the first time duration is positively correlated to the accumulated operating time duration.
Therefore, in the process of acquiring the first time length, the method can consider the influence of the accumulated running time length on the first time length, so that the acquired first time length is closer to the actual condensation requirement and is more flexible and accurate.
For example, the correlation formula for obtaining the first duration according to the accumulated operating duration is as follows:
S3＝S4+k6*(S2-D)/(24*60)
wherein S is3Is a first duration, S2For accumulating the running time, S4Is a reference value of the first time length, D is a reference value of the accumulated running time length, k6Is a correction factor.
Optionally, parameter S4、D、k6Can be calibrated according to the actual conditions, e.g. S4Can be scaled to 6 minutes, D can be scaled to 90 days, k6It can be calibrated to 0.05.
And S304, controlling the air conditioner to enter a heating mode, increasing the temperature of the indoor coil to a second target temperature, and continuing for a second preset time.
In an embodiment of the present invention, after the air conditioner finishes the cooling and water condensing stage, the air conditioner may be further controlled to enter a heating mode to remove the residual condensed water inside the indoor heat exchanger.
And calibrating the second target temperature and the second preset time according to the actual condition.
Optionally, when the air conditioner is in the heating mode, the temperature of the indoor coil of the air conditioner can be increased by adjusting the operating parameters of the air conditioner. The operating parameters of the air conditioner may include an operating frequency of the compressor, a rotational speed of the indoor fan, an opening degree of the throttling element, and the like, which are not listed here. Optionally, the throttling element may comprise an expansion valve. For example, when the air conditioner is operated in the heating mode, if the operating frequency of the compressor is increased, and/or the rotational speed of the indoor fan is decreased, and/or the opening degree of the throttling element is decreased, the temperature of the indoor coil is increased according to the principle of the refrigeration cycle.
It should be noted that, for details not disclosed in the self-cleaning method of the air conditioner in the embodiment of the present invention, please refer to details disclosed in the above embodiments of the present invention, which are not described herein again.
In summary, according to the self-cleaning method of the air conditioner in the embodiment of the present invention, after the air conditioner finishes the cooling and water condensing stage, the air conditioner can be controlled to enter the heating mode, and the temperature of the indoor coil is raised to the second target temperature, and the heating mode lasts for the second preset time period, so as to remove the residual condensed water inside the indoor heat exchanger, prevent the residual condensed water from flowing out along the outer surface of the air conditioner, so as to solve the problem of inconvenience to the normal use of the user, further have the effect of high temperature sterilization and mold removal, and protect the health of the user.
A self-cleaning method of an air conditioner according to another embodiment of the present invention will be described with reference to fig. 4.
As shown in fig. 4, the self-cleaning method of an air conditioner according to an embodiment of the present invention includes the following steps:
s401, responding to a self-cleaning instruction aiming at the air conditioner, and controlling the air conditioner to enter a refrigeration and water condensation stage.
S402, acquiring a first water condensation time length required by the air conditioner and/or a first target temperature of an evaporator in the air conditioner.
And S403, identifying that the operation time of the air conditioner in the condensation water making stage reaches a first condensation time, and/or the temperature of an indoor coil of the air conditioner is reduced to a first target temperature, and ending the condensation water making stage.
For specific descriptions of S401 to S403, reference may be made to the descriptions of relevant contents in the above embodiments, and details are not described here.
And S404, controlling the air conditioner to enter a frosting stage and continuously operating for a third time.
In an embodiment of the present invention, after the air conditioner finishes the refrigeration and condensation stage, the air conditioner may further continue to operate in the refrigeration mode and control the air conditioner to enter the frosting stage, so that the condensed water remaining inside the indoor heat exchanger is frosted, and an effect of further cleaning the indoor heat exchanger is achieved.
For the contents of how the temperature of the indoor coil is reduced in the cooling mode of the air conditioner, reference may be made to the above embodiments, and details are not described herein.
The third time period may be calibrated according to actual conditions, for example, may be calibrated to 10 minutes.
Alternatively, the third time period may be acquired according to the accumulated operation time period of the air conditioner.
It can be understood that the longer the air conditioner is operated in the frosting stage, the more frost is generated by the indoor heat exchanger, and it can be known that the third time period is positively correlated with the actually required frosting amount. Wherein the actually required amount of frost formation is related to the accumulated running time. The accumulated operation time can reflect the dust deposition degree of the indoor heat exchanger, the longer the accumulated operation time is, the higher the dust deposition degree of the indoor heat exchanger is, and the more the required frost formation amount is, namely, the actually required frost formation amount is positively correlated with the accumulated operation time.
From the above analysis, it can be seen that the third time period is positively correlated to the accumulated operation time period.
Therefore, in the process of acquiring the third time length, the influence of the accumulated running time length on the third time length can be considered, so that the acquired third time length is closer to the actual frosting requirement and is more flexible and accurate.
As another possible embodiment, the third time period may be obtained according to the first condensed water time period required by the air conditioner.
It can be understood that, the longer the operation time of the air conditioner in the condensate water making stage is, the more condensate water is generated by the indoor heat exchanger, and in order to fully frost the residual water of the indoor heat exchanger, the longer the operation time of the indoor heat exchanger in the frost forming stage is, and it is known that the third time period is positively correlated to the first condensate water time period.
Therefore, in the process of acquiring the third time length, the influence of the first water condensation time length on the third time length can be considered, so that the acquired third time length is matched with the first water condensation time length, the actual frosting requirement is more close to, and the method is more flexible and accurate.
And S405, controlling the air conditioner to defrost by adopting a heating mode or an air supply mode, and continuously operating for a fourth time.
In an embodiment of the present invention, after the air conditioner finishes the frosting stage, the air conditioner may be further controlled to enter the defrosting stage, so that the frost on the outer surface of the indoor heat exchanger is liquefied, and the generated condensed water will wash away the originally wrapped dust and dirt, thereby achieving the effect of further cleaning the indoor heat exchanger.
It should be noted that, when the air conditioner operates in the defrosting stage, the operation mode of the air conditioner may be a heating mode or an air supply mode. If the air conditioner operates in the heating mode, the defrosting efficiency is high, the waiting time of a user is short, and the energy consumption is high. If the air conditioner runs in an air supply mode, the defrosting efficiency is low, the waiting time of a user is long, and the energy consumption is saved.
Optionally, the outdoor temperature may be detected, and the operation mode of the air conditioner in the defrosting stage may be controlled according to the magnitude relationship between the outdoor temperature and the preset temperature threshold. If the outdoor temperature is greater than or equal to the preset temperature threshold value, the outdoor temperature is higher, the defrosting effect is better when the air supply mode is adopted, and the air conditioner can be controlled to directly enter the air supply mode for defrosting; if the outdoor temperature is smaller than the preset temperature threshold value, the outdoor temperature is lower, the defrosting effect is poor by adopting the air supply mode, and the waiting time of a user is longer, the air conditioner can be controlled to enter the heating mode to defrost. The preset temperature threshold may be calibrated according to actual conditions, for example, may be calibrated to 20 ℃.
Therefore, the method can determine the operation mode of the air conditioner in the defrosting stage according to the outdoor temperature, the flexibility is high, the air supply mode is adopted for defrosting when the outdoor temperature is high, energy is saved, the heating mode is adopted for defrosting when the outdoor temperature is low, the waiting time of a user is saved, and the comfort level of the user is improved.
And the fourth duration can be calibrated according to the actual condition.
Alternatively, the fourth time period may be acquired according to the third time period of the air conditioner frosting stage.
It can be understood that, the longer the operation time of the air conditioner in the defrosting stage is, the more the amount of frost generated by the indoor heat exchanger is, and in order to defrost more thoroughly, the greater the operation time of the corresponding defrosting stage is, and it is known that the fourth time period is positively correlated to the third time period.
Therefore, in the process of acquiring the fourth time length, the method can consider the influence of the third time length on the fourth time length, so that the acquired fourth time length is matched with the third time length, is closer to the actual defrosting requirement, and is more flexible and accurate.
And S406, controlling the air conditioner to ventilate for a fifth time after defrosting is finished.
In an embodiment of the invention, after the defrosting stage of the air conditioner is finished, the air conditioner can be controlled to ventilate to remove residual condensed water in the indoor heat exchanger, so that the problem that the residual condensed water flows out along the outer surface of the air conditioner to cause inconvenience to normal use of a user is solved, residual heat in the indoor heat exchanger can be blown out, damage to components in the air conditioner caused by residual heat of the indoor heat exchanger is avoided, and the operation reliability of the air conditioner is ensured.
The fifth time period may be calibrated according to actual conditions, for example, may be calibrated to 5 minutes.
It should be noted that, for details not disclosed in the self-cleaning method of the air conditioner in the embodiment of the present invention, please refer to details disclosed in the above embodiments of the present invention, which are not described herein again.
In summary, according to the self-cleaning method of the air conditioner of the embodiment of the invention, after the air conditioner finishes the refrigeration and water condensation stage, the air conditioner can be controlled to enter the frosting, defrosting and ventilating stages, the moisture remained in the indoor heat exchanger is frosted when meeting cold first and then liquefied when meeting heat, and the generated condensed water can flush the dust and dirt remained in the indoor heat exchanger, so as to realize the effect of further cleaning the indoor heat exchanger.
In order to make the present invention more clear to those skilled in the art, fig. 5 is a flowchart illustrating a self-cleaning method of an air conditioner according to an embodiment of the present invention, and as shown in fig. 5, the control method may include the following steps:
s501, responding to a self-cleaning instruction aiming at the air conditioner, and controlling the air conditioner to enter a refrigeration and water condensation stage.
S502, acquiring environment information of the environment where the air conditioner is located, and acquiring first water condensation time according to the environment information, the indoor coil temperature of the air conditioner and the accumulated running time of the air conditioner.
And S503, determining a first target temperature of an evaporator in the air conditioner according to the environment information of the air conditioner.
S504, recognizing that the operation time of the air conditioner in the water condensation making stage reaches a first water condensation time, and/or the temperature of an indoor coil of the air conditioner is reduced to a first target temperature, and ending the water condensation making stage.
And S505, controlling the air conditioner to enter a frosting stage and continuously operating for a third time.
S506, detecting the outdoor temperature, and identifying whether the outdoor temperature is greater than or equal to a preset temperature threshold value.
If yes, go to step S507; if not, step S508 is performed.
And S507, controlling the air conditioner to enter an air supply mode for defrosting, and continuously operating for a fourth time.
And S508, controlling the air conditioner to enter a heating mode for defrosting, and continuously operating for a fourth time period.
And S509, controlling the air conditioner to ventilate for a fifth time after defrosting is finished.
For the specific description of the steps, reference is made to the descriptions of the related contents in the above embodiments, which are not described herein again.
On the basis of the above embodiment, as shown in fig. 6, before responding to the self-cleaning instruction for the air conditioner, the method further includes:
s601, acquiring the accumulated operation time of the air conditioner, wherein the accumulated operation time of the air conditioner reaches a first preset time, and periodically detecting the indoor relative humidity.
S602, identifying whether the indoor relative humidity is greater than a preset humidity threshold value and continuously presetting a second preset time.
If yes, go to step S603; if not, returning to continue to execute the steps of periodically detecting the indoor relative humidity and the subsequent steps thereof.
And S603, sending a starting prompt of the self-cleaning mode of the air conditioner to a user.
It should be noted that the first preset time, the preset humidity threshold, and the second preset time may all be calibrated according to actual conditions, for example, the first preset time may be calibrated to 10 days, the preset humidity threshold may be calibrated to 40%, and the second preset time may be calibrated to 30 minutes.
It can be understood that when the accumulated operation time of the air conditioner is short, the dust deposition amount of the indoor heat exchanger is small, and in this case, if the self-cleaning mode of the air conditioner is started, problems of excessive cleaning, energy waste and the like are caused. When the indoor relative humidity is low, condensed water is difficult to form in the refrigeration and condensation stage, and under the condition, if the self-cleaning mode of the air conditioner is started, the problems of less condensed water, incomplete cleaning, energy waste and the like can be caused.
Therefore, after the accumulated running time of the air conditioner and the indoor relative humidity both accord with the starting condition of the self-cleaning mode, the method sends the starting prompt of the self-cleaning mode of the air conditioner to the user, so that the self-cleaning effect of the air conditioner can be ensured, the energy waste is avoided, and the interaction degree between the air conditioner and the user is also improved.
The sending of the start-up prompt of the self-cleaning mode of the air conditioner to the user may include displaying a prompt message in a display area of the remote controller and/or the air conditioner, and sending the prompt message through an air conditioner APP in the mobile terminal of the user.
S604, detecting that the user does not read the start-up reminder within a third preset time, and sending the start-up reminder of the self-cleaning mode of the air conditioner to the user again.
S605, detecting that the user reads the start prompt within a third preset time, and sending a self-cleaning instruction aiming at the air conditioner if the user selects to start self-cleaning.
S606, detecting that the user reads the start prompt within a third preset time length, and if the user does not select to start or close self-cleaning, continuing to wait for the operation instruction of the user.
The third preset time period may be calibrated according to actual conditions, for example, may be calibrated to 5 minutes.
For example, the reminding information can be sent through the air conditioner APP in the mobile terminal of the user, whether the user reads the reminding information can also be detected, and if the user does not read the information within the third preset time period, the reminding information can also be sent through the air conditioner APP again; if the user reads the information within a third preset time and selects to start self-cleaning, a self-cleaning instruction for the air conditioner can be sent out; if the user reads the information within the third preset time length but does not select to start or close the self-cleaning, the user can continue to wait for the operation instruction of the user.
As another possible implementation manner, the accumulated operation duration of the air conditioner is obtained, the indoor relative humidity is periodically detected after the accumulated operation duration of the air conditioner reaches the first preset duration, and when the indoor relative humidity is greater than the preset humidity threshold and continues for the second preset duration, the self-cleaning instruction for the air conditioner can be directly sent out.
On the basis of the embodiment, after the self-cleaning instruction for the air conditioner is responded, the operation parameters of the air conditioner are displayed. The operation parameters comprise information such as the stage of the air conditioner in the self-cleaning mode, the temperature of the indoor coil, the first target temperature and the like. It should be noted that the stage of the air conditioner in the self-cleaning mode may include stages of cooling and condensing water, frosting, defrosting, drying, ventilating, etc., which are not limited herein. Optionally, the operating parameters of the air conditioner may be displayed on the remote controller and/or the internal panel and/or the air conditioner APP in the user's mobile terminal. It is understood that when the air conditioner is in the self-cleaning mode, an icon representing self-cleaning may also be displayed on the remote controller.
Therefore, the method enables the user to know the operation parameters of the air conditioner in the self-cleaning mode in real time, and the user can judge the self-cleaning effect, the remaining time and other information according to the operation parameters, so that the interaction degree between the air conditioner and the user is improved.
For example, as shown in fig. 7, displaying the operation parameters of the air conditioner may include:
s701, displaying a refrigeration and condensation stage: self-cleaning icons are displayed on the remote controller, and the indoor coil temperature and/or the target condensate water temperature are displayed on the panel of the internal machine.
S702: refrigeration frosting stage display: the indoor coil temperature and/or the target frosting temperature are displayed on the inner panel.
S703: and (3) defrosting stage display: and the indoor coil temperature and/or the target defrosting temperature are/is displayed on the inner panel.
