Detailed Description
So that the manner in which the features and elements of the disclosed embodiments can be understood in detail, a more particular description of the disclosed embodiments, briefly summarized above, may be had by reference to the embodiments, some of which are illustrated in the appended drawings. In the following description of the technology, for purposes of explanation, numerous details are set forth in order to provide a thorough understanding of the disclosed embodiments. However, one or more embodiments may be practiced without these details. In other instances, well-known structures and devices may be shown in simplified form in order to simplify the drawing.
In the embodiment of the disclosure, the air conditioner can be intelligently cleaned by adjusting the operation parameters in the self-cleaning process, so that the intelligence and the cleaning degree of the air conditioner are improved.
Fig. 1 is a schematic flow chart of an air conditioner self-cleaning control method in an embodiment of the present disclosure. As shown in fig. 1, the process of the air conditioner self-cleaning control may include:
step 101: and under the condition that the self-cleaning operation of the air conditioner is started for the current times, acquiring the current filth blockage information of the heat exchanger in the air conditioner.
In the disclosed embodiment, the self-cleaning strategy of the air conditioner may include a single self-cleaning mode and a multiple self-cleaning mode. Wherein, the multiple self-cleaning mode may include: and carrying out self-cleaning twice or more times. After the air conditioner starts the multi-time self-cleaning mode, the indoor unit of the air conditioner can be automatically cleaned for two times or more, and then the outdoor unit of the air conditioner can be automatically cleaned. Specifically, the self-cleaning operation is performed several times, and the self-cleaning operation is determined according to the operation information of the corresponding air conditioner after the self-cleaning process of the indoor unit or the outdoor unit is completed each time.
In the embodiment of the present disclosure, no matter whether the indoor unit of the air conditioner performs one or more self-cleaning processes or the outdoor unit of the air conditioner performs one or more self-cleaning processes, each self-cleaning process is a process of condensing and increasing humidity, and then frosting and defrosting the surface of the heat exchanger, which may specifically include: firstly, controlling an electronic expansion valve to reduce the temperature of a heat exchanger to be below the dew point temperature, and controlling a fan to continuously bring moisture in the air to the surface of the heat exchanger for condensation; then, adjusting at least one device such as the frequency of a compressor and an electronic expansion valve to reduce the surface temperature of the heat exchanger, and simultaneously closing a fan to quickly frost the surface of the heat exchanger; and finally, adjusting the electronic expansion valve, increasing the rotating speed of the fan, quickly defrosting and flushing the heat exchanger by using water, thereby realizing a primary self-cleaning process. Therefore, the self-cleaning operation of the air conditioner can be influenced by the time, the frosting temperature, the fan speed, the compressor frequency, the opening degree of the electronic expansion valve and other parameters corresponding to the three stages of condensation, frosting and defrosting.
In the embodiment of the disclosure, no matter the air conditioner performs single self-cleaning or multiple self-cleaning, no matter the indoor unit of the air conditioner performs self-cleaning or the outdoor unit of the air conditioner performs self-cleaning, self-cleaning control can be performed under the condition that the self-cleaning operation of the air conditioner is determined to be started for the current times.
In some embodiments, in case of obtaining the self-cleaning instruction information, it may be determined that the air conditioner starts a current number of self-cleaning operations. For example: and receiving a single self-cleaning instruction sent by a user through the remote control terminal, and starting the self-cleaning operation of the air conditioner for the current times, namely starting one self-cleaning operation. Or, a plurality of self-cleaning instructions sent by a user through the remote control terminal are received, and then the current self-cleaning operation of the air conditioner can be started, namely the first self-cleaning operation is started.
In some embodiments, when the previous self-cleaning operation is completed, and the operation information of the air conditioner does not meet the set condition, the self-cleaning operation of the air conditioner started for the current time is determined. The air conditioner may have a strategy of multiple self-cleaning, so that the operation information of the air conditioner can be acquired after each self-cleaning operation is completed, and the air conditioner is determined to start the next self-cleaning operation under the condition that the acquired operation information of the air conditioner does not meet the set conditions. Thus, the self-cleaning operation corresponding to the current times needs to be determined according to the operation information after the previous self-cleaning operation is completed.
Wherein, the air conditioner operation information may include: at least one of a number of runs, a dirty plug level value, etc., and the dirty plug level value may include: at least one of the thickness value of the deposited dust, the wind speed of the air outlet, the rotating speed and the power of the fan and the like.
The thickness value of the deposited ash on the heat exchanger can be obtained through an infrared sensor arranged on the heat exchanger, and the dirty blockage degree value of the heat exchanger in the operation information can be determined according to the thickness value of the deposited ash.
The wind speed of the corresponding air outlet of the heat exchanger can be acquired through the wind speed sensor, and the dirty blockage degree value of the heat exchanger in the operation information can be determined according to the corresponding relation between the preset wind speed and the dirty blockage degree value.
The water quality turbidity value of the condensed water in the condensation pipeline of the air conditioner can be obtained through the water quality monitoring equipment, and the dirty blockage degree value of the heat exchanger in the operation information is determined according to the preset corresponding relation between the water quality turbidity value and the dirty blockage degree value.
Of course, other parameters of the air conditioner can be obtained, and the corresponding dirty blockage degree value is determined, which is not specifically listed.
In some embodiments, the number N of times of indoor cleaning in the multiple self-cleaning mode may be preset, so that when the number of times of operation corresponding to the previous time in the acquired operation information is greater than or equal to the preset number N of times of indoor cleaning, it may be determined that the operation information satisfies the set condition, and when the number of times of operation corresponding to the previous time in the operation information is less than the preset number N of times of cleaning, it may be determined that the operation information does not satisfy the set condition, and the current number of times of self-cleaning operation of the air conditioner may be started.
In some embodiments, a preset dirty plugging degree value in the multi-time self-cleaning mode may be configured, so that when the dirty plugging degree value of the heat exchanger in the acquired operation information after the previous self-cleaning operation is completed is greater than or equal to the preset dirty plugging degree, it is determined that the operation information does not meet the set condition, and the current self-cleaning operation of the air conditioner may be started.
And the air conditioner starts the self-cleaning operation for the current times, so that the current filth blockage information of the heat exchanger in the air conditioner can be obtained. Also, the dirty information may be embodied by one, two or more kinds of information, and therefore, obtaining the current dirty information of the heat exchanger in the air conditioner includes at least one of the following ways: determining current filth blockage information according to current water quality information of condensed water in a condensation pipeline corresponding to the air conditioner heat exchanger; determining current filth blockage information according to current wind speed information of an air outlet of the evaporator; and determining the current dirty and blockage information according to the current accumulated dust thickness information of the evaporator.
The filth blockage information can be embodied by various information, and can also be embodied by converting the various information into corresponding filth blockage values, so that the current deposition thickness value of the heat exchanger can be obtained by an infrared sensor arranged on the heat exchanger, and the current filth blockage degree value of the heat exchanger can be determined according to the current deposition thickness value. Or, the current wind speed of the corresponding air outlet of the heat exchanger is obtained through the wind speed sensor, and the current dirty blockage degree value of the heat exchanger can be determined according to the corresponding relation between the preset wind speed and the dirty blockage degree value. Or, the current water turbidity value of the condensed water in the condensation pipeline corresponding to the air-conditioning heat exchanger can be obtained through the water quality monitoring equipment, and the current dirty blockage degree value of the heat exchanger is determined according to the corresponding relation between the preset water turbidity value and the dirty blockage degree value.
Generally, when the air conditioner executes a single self-cleaning mode or determines to start the first self-cleaning operation, the current ash deposition thickness value on the heat exchanger can be obtained through an infrared sensor arranged on the heat exchanger, and the current dirty blockage degree value of the heat exchanger can be determined according to the ash deposition thickness value. Or, the current wind speed of the corresponding air outlet of the heat exchanger is obtained through the wind speed sensor, and the current dirty blockage degree value of the heat exchanger can be determined according to the corresponding relation between the preset wind speed and the dirty blockage degree value. And under the condition of starting self-cleaning operation for the second time, the third time, … time or the nth time, the corresponding dirty blocking degree value can be determined according to the deposited dust thickness or the wind speed, the current water quality turbidity value of condensed water in a condensation pipeline corresponding to the air-conditioning heat exchanger can be obtained through the water quality monitoring equipment, and the current dirty blocking degree value of the heat exchanger can be determined according to the preset corresponding relation between the water quality turbidity value and the dirty blocking degree value.
In the above triggering condition for determining the self-cleaning operation of the air conditioner started for the current number of times, a dirty degree value in the corresponding operation information may have been already obtained when the previous self-cleaning operation is completed. Of course, in the above trigger condition of the self-cleaning operation for determining the current number of times of starting the air conditioner, if the operation information only includes the number of times of operation, it is still necessary to reflect the corresponding current filth blockage information by acquiring one of the current water quality information, the current wind speed information, the current thickness information, and the like.
Step 102: and determining the current target coil temperature of the heat exchanger in the self-cleaning running frosting process according to the current filth blockage information.
In some embodiments, the surface temperature of the heat exchanger can be between-5 ° to-20 ° during the frosting process of the self-cleaning operation of the air conditioner, and the more serious the filth blockage, the lower the target coil temperature of the air conditioner is configured. For example: the quality of water of the condensate water in the condensation pipeline corresponding to the air conditioner heat exchanger is checked, the more the pollutant particles in the condensate water are, the larger the turbidity value of the water quality is, and the larger the corresponding filth blockage degree value is, so that the determined temperature of the target coil pipe is lower. Or, the lower the wind speed of the air outlet corresponding to the heat exchanger is acquired by the wind speed sensor, the smaller the gap between the fins of the heat exchanger is, the larger the corresponding filth blockage degree value is, and thus, the lower the determined temperature of the target coil pipe is.
Therefore, according to the relationship between the higher the degree of filth blockage and the lower the target coil temperature in the set temperature range, the corresponding relationship between the filth blockage degree value of the heat exchanger and the target coil temperature on the surface of the heat exchanger can be configured. Therefore, the current target coil temperature corresponding to the current filth blockage degree value is determined according to the configured corresponding relation, namely the current target coil temperature of the heat exchanger in the self-cleaning running frosting process can be determined according to the current filth blockage information.
Step 103: and controlling the air conditioner to perform self-cleaning operation for the current times, so that the temperature of the coil of the heat exchanger in the frosting process is the current target temperature of the coil.
The method comprises the steps that the current target coil temperature of the air conditioner in the self-cleaning operation process is determined, namely the self-cleaning of the air conditioner can be operated according to the determined parameter, wherein the coil temperature of the heat exchanger in the frosting process can be the current target coil temperature by adjusting one, two or more modes of the frequency of a compressor, the opening degree of an electronic expansion valve and the rotating speed of a fan.
Therefore, in the embodiment, the target coil temperature of the heat exchanger in the frosting process of the self-cleaning operation of the air conditioner can be determined according to the filth blockage information of the heat exchanger of the air conditioner, so that different self-cleaning operation parameters are adopted for the air conditioners with different filth blockage degrees, the intelligence of the air conditioner is improved, the cleaning degree of the air conditioner is improved, the probability of poor heat exchange capacity, bacterial breeding, dust pollution caused by blowing and other adverse problems caused by filth blockage of an indoor unit is reduced, and the overall performance of the air conditioner is further improved.
Certainly, in the self-cleaning operation process of the air conditioner, other operation parameters can be intelligently adjusted, and in some embodiments, after the current filth blockage information is obtained, the first time of the operation of the frosting process of the self-cleaning operation can be determined according to the current filth blockage information; and then, controlling the air conditioner to perform self-cleaning operation for the current times, so that the heat exchanger operates for the first time at the current target coil temperature in the frosting process.
Also, the higher the clogging degree of the air conditioner heat exchanger, the longer the frosting operation time will be. In this way, the corresponding relation between the filth blockage degree value and the frosting operation time can be configured within a certain time range, for example, the corresponding relation between the filth blockage degree value and the frosting operation time is configured within 5-20min, so that the first time corresponding to the current filth blockage information is determined; and then, continuously enabling the heat exchanger to operate for the first time at the current target coil temperature in the frosting process by one, two or more modes of adjusting the frequency of the compressor, the opening degree of the electronic expansion valve and the rotating speed of the fan. Therefore, two or more self-cleaning operation parameters can be adjusted according to the filth blockage degree of the air conditioner, and the intelligence and the cleaning degree of the air conditioner are further improved.
The self-cleaning strategy of the air conditioner may include a single self-cleaning mode and a multi-self-cleaning mode. Therefore, in some embodiments, if the multiple self-cleaning mode is adopted, the current operation information of the air conditioner when the current times of self-cleaning operation is finished can be acquired; and under the condition that the current operation information does not meet the set conditions, updating the current times, and determining the self-cleaning operation of the current times after the air conditioner is started and updated. Therefore, through the process of multiple self-cleaning, the cleaning degree of the air conditioner is further improved, the probability of the unfavorable problems of poor heat exchange capacity, bacterial breeding, dust pollution caused by air blowing and the like due to the filth blockage of the indoor unit is reduced, and the overall performance of the air conditioner is further improved.
The following operation flows are integrated into a specific embodiment to illustrate the air conditioner self-cleaning control process provided by the embodiment of the present invention.
In one embodiment of the present disclosure, the air conditioner employs a multiple self-cleaning mode, including cleaning of the indoor evaporator and cleaning of the outdoor evaporator, and also maintains a first correspondence between a dirty blockage level value and a target coil temperature on the surface of the heat exchanger.

Step 207: the first current number is added by 1 and the process returns to step 202.
Step 208: and starting the second current self-cleaning operation of the air conditioner outdoor unit.
When the self-cleaning of the indoor unit is switched to the self-cleaning of the outdoor unit, the corresponding second current frequency is 1.
Step 209: and acquiring a current second wind speed value of the wind outlet corresponding to the outdoor evaporator through the wind speed sensor, and determining a current second dirty blockage degree value corresponding to the current second wind speed value.
Step 210: and determining the current second target coil temperature corresponding to the current second dirty plugging degree value according to the first corresponding relation between the stored dirty plugging degree value and the target coil temperature on the surface of the heat exchanger.
Step 211: and controlling the outdoor unit of the air conditioner to perform self-cleaning operation for the second current time, so that the coil temperature of the outdoor heat exchanger in the frosting process is the current second target coil temperature.
Step 212: is it determined whether the second current number of times is smaller than the preset number of times of cleaning? If so, go to step 213, otherwise, the process ends.
Step 213: the second current number is incremented by 1 and the process returns to step 208.
Therefore, in the embodiment, the air conditioner can execute a multi-time self-cleaning strategy, and the target coil temperature of the heat exchanger in the frosting process of the self-cleaning operation of the air conditioner can be determined according to the filth blockage information of the heat exchanger of the air conditioner in each self-cleaning process, so that different self-cleaning operation parameters are adopted for the air conditioners with different filth blockage degrees, the intelligence of the air conditioner is improved, meanwhile, the multi-time self-cleaning strategy also improves the cleaning degree of the air conditioner, reduces the probability of poor heat exchange capacity, bacterial breeding, dust pollution in blowing and other adverse problems caused by filth blockage of an indoor unit, and further improves the overall performance of the air conditioner.
In an embodiment of the present disclosure, a first corresponding relationship between the filth blockage level value and a target coil temperature on the surface of the heat exchanger, and a second corresponding relationship between the filth blockage level value and a time of the operation of the frosting process are saved, and the evaporator may be an evaporator of an indoor unit or an evaporator of an outdoor unit.

That is, in the present embodiment, the control of the first self-cleaning operation is not limited.
Step 302: is the visceral obstruction level greater than or equal to a predetermined visceral obstruction level determined? If so, go to step 303, otherwise, the process ends.

In this way, the temperature determining module 420 may determine the current target coil temperature corresponding to the current dirty plugging level value according to the first corresponding relationship between the stored dirty plugging level value and the target coil temperature on the surface of the heat exchanger.
At this time, the first control module 430 may control the air conditioner to perform the current number of self-cleaning operations, so that the coil temperature of the heat exchanger in the frosting process is the current target coil temperature.
Alternatively, in the embodiment of the present invention, the first control module 430 does not operate, and the time determination module 440 may determine the first time of the operation of the frosting process of the self-cleaning operation corresponding to the current dirty blockage information according to the second corresponding relationship between the saved dirty blockage level value and the operation time of the frosting process. Thus, the second control module 450 may control the air conditioner to perform the current number of self-cleaning operations, so that the heat exchanger operates at the current target coil temperature for the first time during the frosting process.
In case that the current number of times is less than the preset number of times of cleaning, the update control module 460 may add 1 to the current number of times, thereby continuing to control the air conditioner to perform the self-cleaning operation.
Therefore, in the embodiment, the air conditioner self-cleaning control device determines the target coil pipe temperature of the heat exchanger in the frosting process of the self-cleaning operation of the air conditioner according to the filth blockage information of the heat exchanger of the air conditioner, or determines the target coil pipe temperature and the frosting operation time simultaneously, thus, different self-cleaning operation parameters are adopted for the air conditioners with different filth blockage degrees, the intelligence of the air conditioner is improved, and meanwhile, the multiple self-cleaning strategy improves the cleaning degree of the air conditioner, reduces the probability of poor heat exchange capacity, bacterial breeding, dust pollution in blowing and other adverse problems caused by filth blockage of an indoor unit, and further improves the overall performance of the air conditioner.
