Description
Technical Field
The invention relates to the technical field of air conditioners, in particular to an air conditioner and a self-cleaning control method thereof.
Background
When the air conditioner operates in a cooling or heating mode, air in an external environment enters the inside of the machine body along the air inlet, and is blown into the external environment again through the air outlet after heat exchange of the heat exchange plate, in the process, impurities such as dust, large particles and the like mixed in the air can enter the indoor machine along with air inlet flow, although a dustproof filter screen arranged at the air inlet of the air conditioner can filter most of the dust and the particles, a small amount of tiny dust can not be completely blocked and filtered, and the dust can be gradually deposited and attached to the surface of the heat exchange plate along with long-term use of the air conditioner.
Generally, a cleaning method of an air conditioner in the prior art mainly includes two modes of manual cleaning and self cleaning of the air conditioner, wherein the self cleaning mode of the air conditioner is mainly divided into a frost condensation stage and a defrosting stage, wherein, taking an indoor unit of a split air conditioner as an example, in the frost condensation stage, the air conditioner firstly operates in a refrigeration mode, and increases refrigerant output quantity to an indoor heat exchanger, so that moisture in indoor air can be gradually condensed into a frost or ice layer on the outer surface of the heat exchanger, and in the process, the condensed frost layer can be combined with dust, so that the dust is peeled off from the outer surface of the heat exchanger; then, in the defrosting stage, the air conditioner operates in a heating mode to melt the frost layer condensed on the outer surface of the heat exchanger, and dust can be collected into the water receiving tray along with the melted water flow, so that the aim of self-cleaning the indoor unit of the air conditioner can be fulfilled; similarly, when the outdoor unit of the split air conditioner is cleaned, the self-cleaning operation is performed according to a reverse flow to that of the indoor unit, that is, the air conditioner operates the heating mode (the temperature of the outdoor unit is reduced, and the frost is condensed) and then operates the cooling mode (the temperature of the outdoor unit is increased, and the frost is melted).
The starting of the existing self-cleaning mode is mainly controlled by a user manually; because the air conditioner mostly is half confined structural design, lead to the unable audio-visual real-time scale deposit degree of looking over the air conditioner inside, consequently also can't select the suitable opportunity of opening the automatically cleaning mode, appear easily because of the use cost that the frequently start-up of automatically cleaning mode leads to increases or because of the too little problem such as the inside scale deposit of air conditioner that leads to of automatically cleaning mode start-up number of times is more.

The air conditioner comprises an indoor heat exchanger, an outdoor heat exchanger, a throttling device and a compressor, wherein the indoor heat exchanger, the outdoor heat exchanger, the throttling device and the compressor are connected through refrigerant pipelines to form a refrigerant circulation loop, and refrigerant flows along the set flow directions of different operation modes through the refrigerant circulation loop, so that the functions of heating, refrigerating, self-cleaning and the like are realized.
In an embodiment, the operation modes of the air conditioner comprise a refrigeration mode, a heating mode and a self-cleaning mode, wherein the refrigeration mode is generally applied to a high-temperature working condition in summer and used for reducing the indoor environment temperature; the heating mode is generally applied to the low-temperature working condition in winter and is used for increasing the indoor environment temperature; the self-cleaning mode is generally a user's self-selection function mode or self-starting function, and can automatically clean the heat exchanger under the condition that dust and dirt are accumulated on the heat exchanger.
When the air conditioner operates in a refrigeration mode, the set refrigerant flow direction is that high-temperature refrigerant discharged by the compressor firstly flows through the outdoor heat exchanger to exchange heat with the outdoor environment, then flows into the indoor heat exchanger to exchange heat with the indoor environment, and finally the refrigerant flows back to the compressor to be compressed again; in the process, the refrigerant flowing through the outdoor heat exchanger emits heat to the outdoor environment, the refrigerant flowing through the indoor heat exchanger absorbs heat from the indoor environment, and the indoor heat can be continuously discharged to the outdoor environment through the circulating flow of the refrigerant in the refrigerant circulating loop, so that the refrigeration purpose of reducing the temperature of the indoor environment can be achieved.
The set refrigerant flow direction during the heating mode refers to that the high-temperature refrigerant discharged by the compressor firstly flows through the indoor heat exchanger to exchange heat with the outdoor environment, then flows into the outdoor heat exchanger to exchange heat with the indoor environment, and finally flows back to the compressor to be compressed again; in the process, the refrigerant flowing through the indoor heat exchanger emits heat to the indoor environment, the refrigerant flowing through the outdoor heat exchanger absorbs heat from the outdoor environment, and the outdoor heat can be continuously released to the indoor environment through the circulating flow of the refrigerant in the refrigerant circulating loop, so that the heating purpose of improving the temperature of the indoor environment can be achieved.
Generally, since the indoor heat exchanger is a heat exchanger directly used for changing an indoor temperature environment, the degree of cleanliness of the indoor heat exchanger may directly affect the use experience of a user. Therefore, the main application of the self-cleaning mode of the air conditioner of the present invention is an indoor heat exchanger. Of course, the self-cleaning mode of the air conditioner of the present invention may also be used to clean the outdoor heat exchanger, so in a specific embodiment, when the air conditioner of the present invention performs a cleaning process, only one of the indoor heat exchanger and the outdoor heat exchanger may be cleaned, or both of the indoor heat exchanger and the outdoor heat exchanger may be cleaned. It should be understood that if the existing air conditioner uses the same or similar control method as the present invention to perform the self-cleaning operation of the indoor and outdoor heat exchangers, it should be also included in the protection scope of the present invention.
Taking the self-cleaning process of the indoor heat exchanger as an example, the self-cleaning mode of the air conditioner operation of the invention comprises but is not limited to a cold and hot expansion cleaning mode, a high-temperature steam cleaning mode and a frost condensation-defrosting cleaning mode; correspondingly, the self-cleaning process includes, but is not limited to, a cold-hot expansion process, a high-temperature steam cleaning process and a frost formation process; the cold and hot expansion process can be subdivided into two sub-processes of a refrigeration contraction process and a heating expansion process, and the frost formation and defrosting process can be subdivided into two sub-processes of a frost formation process and a defrosting stage.
Optionally, the air conditioner of the present invention may combine multiple self-cleaning processes to perform a cleaning operation on the heat exchanger in the process of performing the self-cleaning mode once according to the actual cleaning requirement, for example, in the process of performing the self-cleaning mode once, a cold-hot expansion process and a frost condensation and defrosting process are sequentially and respectively performed; alternatively, one of the self-cleaning processes may be combined with one or more sub-processes of one or more other self-cleaning processes to perform a cleaning operation on the heat exchanger, such as combining a cold-hot expansion process with a frost-forming process or a defrosting process in a frost-forming and defrosting process during a single self-cleaning mode; alternatively, one or more sub-processes of one of the self-cleaning processes may be combined with one or more sub-processes of the other one or more self-cleaning processes to perform a cleaning operation on the heat exchanger, such as a cooling contraction process or a heating expansion process of a cooling-heating expansion process and a defrosting process of a defrosting process in a single self-cleaning mode. One or more flow combinations in the self-cleaning flows can be preset in the air conditioner, and then the air conditioner can select the adaptive flow combination according to the actual cleaning requirement so as to utilize the cleaning flow defined by the flow combination to clean the heat exchanger for dust removal.
Specifically, for the cold and hot expansion process, taking an indoor heat exchanger as an example, the working process mainly includes two stages which are sequentially performed: a cooling contraction stage defined by a cold-hot expansion process and a heating expansion stage defined by a heating expansion process. The invention utilizes the characteristic that the volume expansion rates of the heat exchanger and the oil stain attached to the heat exchanger are different when the heat exchanger is heated or cooled, and the heat-cold expansion process is executed for one time or multiple times, so that the volume change of the heat exchanger and the oil stain under different cold and hot states can generate a gap between the heat exchanger and the oil stain, the adhesive force of the oil stain on the heat exchanger is reduced, and the effective separation of the heat exchanger and the oil stain is realized.
The invention reduces the temperature of the indoor heat exchanger by adjusting the operation parameters of the compressor, the fan, the throttling device and other components under the condition of controlling the flow direction of the refrigerant limited by the air conditioner in the refrigeration mode in the refrigeration contraction stage, because the oil stain is attached to the indoor heat exchanger and can transfer heat between the two, the temperature of the oil stain per se is also reduced along with the indoor heat exchanger, and because the volume expansion rates of the heat exchanger and the oil stain attached to the heat exchanger are different when the temperature is reduced, the contraction volumes of the heat exchanger and the oil stain are different under the condition of the same temperature variation, so that the oil stain is peeled off from the attachment position of the heat exchanger; after the stage of switching to the heating expansion, the air conditioner is controlled to convey the refrigerant to the indoor heat exchanger in the refrigerant flow direction limited by the heating mode, the temperature of the indoor heat exchanger is raised through adjusting the operation parameters of components such as a compressor, a fan, a throttling device and the like, the temperature of the oil stain per se is also raised along with the indoor heat exchanger, and meanwhile, due to the fact that the volume expansion rates of the indoor heat exchanger and the throttling device are different, under the condition of the same temperature variation amount in the temperature raising process, the volumes of the heat expansion of the indoor heat exchanger and the oil stain are different, the oil stain begins to expand from the contraction attachment position of the heat exchanger in the previous refrigeration contraction stage to increase the volume, the attachment viscosity between the indoor heat exchanger and the oil stain is reduced again, and the oil.
Before the air conditioner leaves a factory, different pollutant samples (such as different types of pollutant samples divided by regions or using areas of the air conditioner) on a heat exchanger used by a user can be collected, the volume expansion rates of the different pollutant samples are measured and calculated in an experiment mode and the like, and parameters and the like corresponding to the optimal stripping effect of the pollutants and the indoor heat exchanger in the switching change process of different refrigerating temperatures and heating temperatures between the two are further measured and calculated according to one or more materials of the indoor heat exchanger; the parameters are prestored in components such as an electric control board, an MCU and the like of the air conditioner, so that when the air conditioner needs to clean the indoor heat exchanger in a self-cleaning mode defined by a cold and hot expansion process, the parameters can be called, and thus data such as running parameters and the like needed to be set when the self-cleaning mode is executed are determined.
For the high-temperature steam cleaning process, in an alternative embodiment, the indoor heat exchanger is a heat exchanger to be cleaned, wherein the indoor unit is provided with a high-temperature steam device, the high-temperature steam device comprises a steam generator and a water storage device, the steam generator is used for generating high-temperature steam, and a steam injection opening of the steam generator faces the indoor heat exchanger, so that the high-temperature steam generated by the steam generator can be injected to the heat exchanger; the water storage device is used for storing water required by the steam generator for generating high-temperature steam; here, after the high-temperature steam is sprayed to the indoor heat exchanger, contaminants such as dust and oil stains adhered to the outer surface of the indoor heat exchanger may be washed away, and the contaminants may be separated from the outer surface of the indoor heat exchanger.
Or, in a further alternative embodiment, the body of the air conditioner comprises a water pan arranged below the indoor heat exchanger; the bottom of the water pan is provided with a heating device which is used for heating the water accumulated in the water pan to a state of generating high-temperature steam. After the heating device is started, the temperature of the water accumulated in the water receiving tray is gradually increased and finally becomes a boiling state, and the accumulated water part becomes gaseous steam; the water pan is positioned below the indoor heat exchanger, and the density of high-temperature steam is low, so that the high-temperature steam can rise and diffuse into gaps of heat exchange fins of the indoor heat exchanger, and oil stains are heated and expanded and separated from the indoor heat exchanger; thus, the air conditioning structure design of the embodiment can also play a role in high-temperature steam cleaning.
For the flow of frost formation and defrosting, the indoor heat exchanger is taken as an example, and the working flow mainly comprises two stages which are sequentially carried out: the defrosting process comprises an indoor heat exchanger defrosting stage defined by a defrosting process and an indoor heat exchanger defrosting stage modern by a defrosting process. In the defrosting stage of the indoor heat exchanger, ice can be condensed and frosted on the indoor heat exchanger of the indoor unit; in the defrosting stage of the indoor heat exchanger, the condensed frost of the indoor heat exchanger in the previous defrosting stage is melted, impurities such as dust and the like can be separated from the indoor heat exchanger along with the melted condensed water, and the cleaning treatment of the indoor heat exchanger is completed.
Specifically, in the operation process of the air conditioner in the refrigeration mode, if the power of the compressor is improved and the output quantity of the refrigerant is increased, the low-temperature refrigerant quantity input into the indoor unit can be increased, the redundant refrigerant cold quantity can reduce the internal temperature of the indoor unit, and when the internal temperature of the indoor unit is lower than the frost condensation critical temperature value (such as 0 ℃), water vapor in air flowing through the indoor unit can be gradually condensed into frost in the indoor unit.
In the heating mode operation process of the air conditioner, the high-temperature refrigerant firstly flows through the indoor heat exchanger, so that the cold energy of the high-temperature refrigerant can increase the internal temperature of the indoor unit, and when the internal temperature of the indoor unit is higher than the frost condensation critical temperature value (such as 0 ℃), the frost condensed in the indoor unit can be gradually melted and dripped, so that the frost can be separated from the indoor heat exchanger. The control method of the invention is that under the condition that the flow direction of the refrigerant limited by the heating mode of the air conditioner is controlled at the defrosting stage of the indoor heat exchanger, the defrosting operation of the indoor heat exchanger is realized by adjusting the operation parameters of components such as a compressor, a fan, a throttling device and the like.
Similarly, when the outdoor heat exchanger is self-cleaned, when the air conditioner flows in the refrigerant flow direction defined by the heating mode, the refrigerant flowing out of the indoor heat exchanger is a medium-temperature refrigerant and the refrigerant flowing into the outdoor heat exchanger after being throttled by the throttling device is a low-temperature refrigerant, so that the low-temperature refrigerant can reduce the temperature of the outdoor heat exchanger, and when the temperature inside the outdoor unit is lower than the frost condensation critical temperature value (such as 0 ℃), water vapor in the air flowing through the outdoor unit can be gradually condensed into frost inside the outdoor unit. Therefore, the ice and the frost of the outdoor heat exchanger are realized while the ice and the frost of the indoor heat exchanger are melted.
And then, the indoor heat exchanger finishes melting ice and defrosting in the defrosting stage of the indoor heat exchanger, self-cleaning of the indoor heat exchanger is finished, the air conditioner enters the defrosting stage of the outdoor heat exchanger, at the moment, the air conditioner is controlled to flow in the direction of the refrigerant flow defined by the refrigeration mode again, the flow direction of the high-temperature refrigerant discharged by the compressor is changed, and the high-temperature refrigerant flows through the outdoor heat exchanger, so that the ice and defrosting of the outdoor heat exchanger can be realized by utilizing the heat of the high-temperature refrigerant, and the self-cleaning process of the outdoor heat exchanger.
In the self-cleaning process, each stage can be performed according to a preset time length, for example, the defrosting stage of the indoor heat exchanger can be preset to 10min, and the defrosting stage of the indoor heat exchanger can be preset to 12min, so that the air conditioner can start timing after the air conditioner enters the defrosting stage of the indoor heat exchanger in the self-cleaning mode, when the time reaches 10min, the air conditioner enters the defrosting stage of the indoor heat exchanger, the defrosting stage of the indoor heat exchanger lasts for 12min, it can be determined that the self-cleaning of the indoor unit is finished, and the air conditioner exits the self-cleaning mode.
In the process that the air conditioner is switched to the flow direction limited by the cooling mode or the heating mode, the opening/closing and the rotating speed of the fans of the indoor unit and the outdoor unit also need to be correspondingly controlled, for example, the indoor fan in the frost condensation stage of the indoor heat exchanger is generally closed or operated at a low speed, and the outdoor fan is opened for operation; and in the defrosting stage of the indoor heat exchanger, the indoor fan is started to operate, and outdoor air is closed or operated at a low speed. Therefore, the indoor unit and the outdoor unit are respectively timed in the self-cleaning process, and when the preset time is reached, the components such as a fan of the air conditioner and the like are controlled to carry out corresponding state switching.
The starting of the existing self-cleaning mode is mainly controlled by a user manually; because the air conditioner mostly is half confined structural design, lead to the unable audio-visual real-time scale deposit degree of looking over the air conditioner inside, consequently also can't select the suitable opportunity of opening the automatically cleaning mode, appear easily because of the use cost that the frequently start-up of automatically cleaning mode leads to increases or because of the too little problem such as the inside scale deposit of air conditioner that leads to of automatically cleaning mode start-up number of times is more.
Therefore, the present invention provides one or more air conditioners and a control method for self-cleaning thereof, so as to solve the technical problems.
Fig. 1 is a first flowchart illustrating a control method for self-cleaning of an air conditioner according to an exemplary embodiment of the present invention.
As shown in fig. 1, the present invention provides a control method for self-cleaning of an air conditioner, which mainly comprises the following steps:
s101, determining a current energy efficiency parameter of the air conditioner;
in the present embodiment, the energy efficiency parameter is a parameter associated with the power consumption of the air conditioner when it is operating; optionally, the energy efficiency parameter includes an energy efficiency ratio, where the energy efficiency ratio is a ratio of cooling/heating capacity of a current heat exchange mode of the air conditioner to an effective input power thereof.
Therefore, when the current energy efficiency parameter is selected as the energy efficiency ratio, in step S101, the current energy efficiency ratio can be calculated according to the refrigeration/heat quantity corresponding to the current heat exchange mode and the effective input power.
Optionally, in the long-term use process of the air conditioner, the energy efficiency parameters of the air conditioner are detected and calculated in real time, and the energy efficiency parameters are packaged and sent to a cloud server erected by an air conditioner service provider to be stored as historical data of the air conditioner; so that the related history data can be called as reference information when the energy efficiency parameter of the air conditioner is corrected at a later stage.
And S102, if the current energy efficiency parameter is lower than a preset first parameter threshold value, controlling the air conditioner to start a self-cleaning mode.
Optionally, the first parameter threshold is calculated according to the following formula:
cop1＝A*cope；
where cop1 is the first parameter threshold; a is a first proportional calculation coefficient, and the value range of the first proportional calculation coefficient is 0.55-0.65; the cope is a reference energy efficiency parameter of the air conditioner.
Before the air conditioner leaves the factory, an energy efficiency parameter when the air conditioner operates with a preset reference parameter can be measured through an experiment and the like, and is used as a reference energy efficiency parameter, such as a reference energy efficiency ratio when the air conditioner operates with the preset reference parameter; at the moment, no pollutant is attached to the air conditioner, so the reference energy efficiency parameter can be used for representing the parameter of the heat exchanger in a pollutant-free state; the pollutant attached to the air conditioner can affect the heat exchange efficiency of the heat exchanger, so the pollutant can also affect the actual energy efficiency parameter of the air conditioner, the energy efficiency parameter measured on the heat exchanger attached with the pollutant is different from the benchmark energy efficiency parameter measured on the heat exchanger not attached with the pollutant in value, and therefore the scaling degree of the heat exchanger of the air conditioner is determined according to the comparison result of the current energy efficiency parameter and the preset benchmark energy efficiency parameter.
The more pollutants are attached to the heat exchanger, the greater the difference between the current energy efficiency parameter and the reference energy efficiency parameter is; the fewer pollutants are attached to the heat exchanger, the smaller the temperature difference between the current energy efficiency parameter and the reference energy efficiency parameter is; namely the two are in positive correlation; therefore, the air conditioner can preset the correlation between the comparison result of the current energy efficiency parameter and the preset reference energy efficiency parameter and the scaling degree of the heat exchanger; therefore, after the current energy efficiency parameter of the heat exchanger is obtained, the scaling degree of the heat exchanger of the air conditioner can be determined according to the reference energy efficiency parameter and the preset incidence relation, and then whether the self-cleaning mode of the air conditioner needs to be started or not can be judged.
In this embodiment, the first parameter threshold is an energy efficiency threshold calculated according to a preset proportional calculation coefficient based on a reference energy efficiency parameter; and under the condition that the current energy efficiency parameter is lower than a preset first parameter threshold value, judging that the scaling degree of a heat exchanger of the air conditioner reaches the condition that cleaning and descaling are required, and controlling the air conditioner to start a self-cleaning mode.
Optionally, the air conditioner in step S102 is configured to interrupt a current heat exchange mode of the air conditioner, and forcibly switch to a self-cleaning mode to perform a cleaning operation on the air conditioner, and if it is determined that self-cleaning is required through steps S101 to S102 in a process that the air conditioner operates in a cooling mode, the air conditioner is controlled to switch from the cooling mode to the self-cleaning mode; after the self-cleaning operation of the air conditioner is finished, the initial heat exchange mode, i.e., the cooling mode in this example, is switched back again.
Therefore, by forcibly switching the operation self-cleaning mode, pollutants such as dust and the like accumulated on the indoor heat exchanger can be prevented from being continuously blown into the indoor environment, so that the physical health of an air conditioner user and the cleanness of the indoor environment are ensured; meanwhile, the self-cleaning operation of the air conditioner can also improve the power consumption state of the air conditioner, and the problems of power consumption increase and energy efficiency reduction caused by excessive pollutants are reduced.
Optionally, the control method of the present invention further includes: and if the current energy efficiency parameter is lower than a preset second parameter threshold and higher than a first parameter threshold, pushing reminding information for starting a self-cleaning mode to a user.
Here, the air conditioner may send a preset reminding message, such as a text or a flash lamp prompting the user to start the self-cleaning mode, through hardware such as a display screen and an indicator lamp of the air conditioner body.
Or, the air conditioner can be in communication connection with a mobile terminal such as a mobile phone of a user through a data network such as a home wifi, and the mobile terminal is provided with an application program and the like provided by a service provider of the air conditioner, so that the air conditioner pushes reminding information for starting the self-cleaning mode to the user by using the application program. Correspondingly, the user can also send instruction information for starting the self-cleaning mode to the air conditioner through the application program, and the air conditioner automatically carries out the self-cleaning mode after receiving the instruction information forwarded by the application program, so that the remote interactive control between the user and an air conditioner product is realized, and the user can also carry out self-cleaning on the air conditioner control under the remote condition.
Optionally, the second parameter threshold is calculated according to the following formula:
cop2＝B*cope；
where cop2 is the second parameter threshold; b is a second proportional calculation coefficient, and the value range of the second proportional calculation coefficient is 0.75-0.85; the cope is a reference energy efficiency parameter of the air conditioner.
Here, the second parameter threshold is greater than the first parameter threshold, so the energy efficiency parameter corresponding to the second parameter threshold is also higher than the energy efficiency parameter corresponding to the first parameter threshold, and the second parameter threshold is used for representing that a structural problem exists on a heat exchanger of the air conditioner, but the physical health of a user and the operation power consumption of the air conditioner do not reach an energy efficiency condition that a self-cleaning mode needs to be forcibly performed.
Optionally, the self-cleaning mode is one of the following modes: a frost-defrosting cleaning mode, a cold and hot expansion cleaning mode and a high-temperature steam cleaning mode.
In one embodiment of the invention, the cold and hot expansion cleaning mode comprises a refrigeration contraction process and a heating expansion process for the heat exchanger to be cleaned;
specifically, the flow for controlling the air conditioner to execute the refrigeration contraction comprises the following steps: controlling the air conditioner to operate a refrigeration mode according to set operation parameters so as to reduce the temperature of the heat exchanger to be cleaned to be below a set refrigeration contraction temperature; optionally, the refrigeration contraction temperature is a frost condensation temperature set at a frost condensation stage of a frost condensation and defrosting process of the air conditioner, that is, the temperature of the heat exchanger to be cleaned is reduced to be below the frost condensation temperature by controlling the air conditioner to operate a refrigeration mode according to set operation parameters.
Here, if the air conditioner does not preset a frost condensation and defrosting process, the frost condensation temperature may be prestored in the air conditioner as one temperature data and associated with the cooling contraction process; in this way, during the cooling contraction flow of the air conditioner, the temperature data can be used as the target temperature of the indoor heat exchanger, and the temperature of the indoor heat exchanger can be reduced to be lower than or equal to the target temperature by adjusting components such as a compressor, a throttling device and a fan of the air conditioner based on the target temperature.
The process of controlling the air conditioner to execute the heating expansion comprises the following steps: controlling the air conditioner to operate a heating mode according to set operation parameters so as to reduce the temperature of the heat exchanger to be cleaned to be above a set heating expansion temperature; optionally, the heating expansion temperature is a defrosting temperature set in a defrosting stage of a defrosting process of the air conditioner, that is, the temperature of the heat exchanger to be cleaned is reduced to be higher than the defrosting temperature by controlling the air conditioner to operate a heating mode according to set operation parameters.
Here, if the air conditioner does not preset a frost condensation and defrosting process, the defrosting temperature may be prestored in the air conditioner as one temperature data and associated with the heating expansion process; in this way, in the heating and expansion flow performed by the air conditioner, the temperature data can be used as the target temperature of the indoor heat exchanger, and the temperature of the indoor heat exchanger in the heating and expansion flow can be reduced to the target temperature or higher by adjusting components such as a compressor, a throttle device, and a fan of the air conditioner based on the target temperature.
Optionally, the heating expansion temperature set in the heating expansion process is 50 ℃.

Optionally, the device for generating steam, which is started to execute the high-temperature steam cleaning process, may be determined according to a usage scenario of the air conditioner; for example, when the use environment is a kitchen and other scenes with more oil stains, a high-temperature steam device can be selected to perform steam cleaning on the indoor heat exchanger; and when the service environment is the more scene of greasy dirt such as bedroom, then the optional heating device that opens, here, the mode that heating device produced high temperature steam compares in high temperature steam device, and its steam air current is more soft and the noise that produces is less, is applicable to the little scene of demand noise, has reduced the uncomfortable influence that the air conditioner execution high temperature steam washs the flow and causes the user. Here, the usage scenario of the air conditioner may be set by user input.
Optionally, before the heating device of water collector bottom is opened in the control, control air conditioner execution high temperature steam washs the flow, still includes: detecting the water quantity of the water receiving tray; if the water quantity meets the preset water quantity condition, controlling to start a heating device at the bottom of the water receiving tray; if the water quantity does not meet the preset water quantity condition, the heating device at the bottom of the water receiving tray is not controlled to be started; and/or controlling the water supply pipe to replenish water to the water receiving tray.
Here, the source of the water using the heating device to generate the high-temperature steam is the water accumulated in the water receiving tray; when the water in the water receiving tray is insufficient, if the heating device still runs, the problem of dry burning of the water receiving tray can be caused, and the problems of fire and the like can be easily caused; therefore, before the heating device at the bottom of the water pan is controlled to be started, the water quantity of the water pan is detected, and the heating device at the bottom of the water pan is controlled to be started only under the condition that the water quantity meets the preset water quantity condition, so that the safety of the air conditioner for executing a high-temperature steam cleaning process is ensured.
Fig. 2 is a second flowchart illustrating a self-cleaning control method of an air conditioner according to another exemplary embodiment of the present invention.
As shown in fig. 2, the present invention provides another control method for self-cleaning of an air conditioner, which mainly comprises the following steps:
s201, determining a current energy efficiency parameter of the air conditioner;
in this embodiment, the specific implementation manner of step S201 may refer to step S202 in the foregoing, which is not described herein again.
S202, detecting the activity state of personnel in the indoor environment where the air conditioner is located;
optionally, the air conditioner is further provided with an infrared sensing device, and the infrared sensing device can sense infrared heat signals in a set indoor area; in the step S202, the air conditioner can judge whether a user exists in the indoor set area according to the infrared heat signal sensed by the infrared sensing device; here, the human activity state detected in step S202 is whether a user exists in the indoor environment, and the detection result of the human activity state includes a human state and an unmanned state;
s203, if the current energy efficiency parameter is lower than a preset first parameter threshold value and the indoor environment is determined to be in an unmanned state, controlling the air conditioner to start a self-cleaning mode.
Optionally, the first parameter threshold is calculated according to the following formula:
cop1＝A*cope；
where cop1 is the first parameter threshold; a is a first proportional calculation coefficient, and the value range of the first proportional calculation coefficient is 0.55-0.65; the cope is a reference energy efficiency parameter of the air conditioner.
Before the air conditioner leaves the factory, an energy efficiency parameter when the air conditioner operates with a preset reference parameter can be measured through an experiment and the like, and is used as a reference energy efficiency parameter, such as a reference energy efficiency ratio when the air conditioner operates with the preset reference parameter; at the moment, no pollutant is attached to the air conditioner, so the reference energy efficiency parameter can be used for representing the parameter of the heat exchanger in a pollutant-free state; the pollutant attached to the air conditioner can affect the heat exchange efficiency of the heat exchanger, so the pollutant can also affect the actual energy efficiency parameter of the air conditioner, the energy efficiency parameter measured on the heat exchanger attached with the pollutant is different from the benchmark energy efficiency parameter measured on the heat exchanger not attached with the pollutant in value, and therefore the scaling degree of the heat exchanger of the air conditioner is determined according to the comparison result of the current energy efficiency parameter and the preset benchmark energy efficiency parameter.
The more pollutants are attached to the heat exchanger, the greater the difference between the current energy efficiency parameter and the reference energy efficiency parameter is; the fewer pollutants are attached to the heat exchanger, the smaller the temperature difference between the current energy efficiency parameter and the reference energy efficiency parameter is; namely the two are in positive correlation; therefore, the air conditioner can preset the correlation between the comparison result of the current energy efficiency parameter and the preset reference energy efficiency parameter and the scaling degree of the heat exchanger; therefore, after the current energy efficiency parameter of the heat exchanger is obtained, the scaling degree of the heat exchanger of the air conditioner can be determined according to the reference energy efficiency parameter and the preset incidence relation, and then whether the self-cleaning mode of the air conditioner needs to be started or not can be judged.
In this embodiment, the first parameter threshold is an energy efficiency threshold calculated according to a preset proportional calculation coefficient based on a reference energy efficiency parameter; and under the condition that the current energy efficiency parameter is lower than a preset first parameter threshold value, judging that the scaling degree of a heat exchanger of the air conditioner reaches the condition that cleaning and descaling are required, and controlling the air conditioner to start a self-cleaning mode.
Optionally, the air conditioner in step S202 is to interrupt the current heat exchange mode of the air conditioner, and forcibly switch to the self-cleaning mode to perform cleaning operation on the air conditioner, and if it is determined that self-cleaning is required through steps S201 to S202 in the process that the air conditioner operates in the cooling mode, the air conditioner is controlled to switch from the cooling mode to the self-cleaning mode; after the self-cleaning operation of the air conditioner is finished, the initial heat exchange mode, i.e., the cooling mode in this example, is switched back again.
Here, the condition for controlling the air conditioner to turn on the self-cleaning mode further includes determining that the indoor environment is an unattended state. Because the operation parameters of the air conditioner in the self-cleaning mode are different from the operation parameters set by the air conditioner in the initial heat exchange mode, the temperature and the humidity of the indoor environment can also change in the operation process of the self-cleaning mode, and if the refrigeration mode is interrupted, the temperature of the indoor environment can gradually rise; here, the temperature and humidity change of the indoor environment can cause discomfort of a user currently in the indoor environment, so that the air conditioner of the application operates the self-cleaning mode when the user does not exist in the indoor environment, and visual influence of the self-cleaning mode on the comfort of the user during the operation of the air conditioner is reduced.
Therefore, by forcibly switching the operation self-cleaning mode, pollutants such as dust and the like accumulated on the indoor heat exchanger can be prevented from being continuously blown into the indoor environment, so that the physical health of an air conditioner user and the cleanness of the indoor environment are ensured; meanwhile, the self-cleaning operation of the air conditioner can also improve the power consumption state of the air conditioner, and the problems of power consumption increase and energy efficiency reduction caused by excessive pollutants are reduced.
Optionally, the control method of the present invention further includes: and if the current energy efficiency parameter is lower than a preset second parameter threshold and higher than a first parameter threshold, pushing reminding information for starting a self-cleaning mode to a user.

and S303, if the current energy efficiency parameter is lower than a preset first parameter threshold value, and it is determined that the personnel in the indoor environment are in a static state and the body surface temperature is not higher than a set temperature, controlling the air conditioner to start a self-cleaning mode.
Optionally, the first parameter threshold is calculated according to the following formula:
cop1＝A*cope；
where cop1 is the first parameter threshold; a is a first proportional calculation coefficient, and the value range of the first proportional calculation coefficient is 0.55-0.65; the cope is a reference energy efficiency parameter of the air conditioner.

Fig. 4 is a fourth flowchart illustrating a control method of self-cleaning of an air conditioner according to another exemplary embodiment of the present invention.
As shown in fig. 4, the present invention provides another control method for self-cleaning of an air conditioner, which mainly comprises the following steps:
s401, determining a current energy efficiency parameter of the air conditioner;
in this embodiment, the specific implementation manner of step S401 may refer to step S101 in the foregoing, which is not described herein again.
S402, obtaining an energy efficiency average value parameter in a user group area to which an air conditioner belongs;
here, the user group area may be divided into the same user group area in units of one or several adjacent cells, such as a cell a and B; or one or more administrative regions such as county or city, such as Chaoyang region in Beijing is a user group region, and Hai lake region is another user group region; here, because the living environments of the users in the same user group area are similar, the factors causing pollution of the indoor heat exchanger of the air conditioner are also approximately same, and the factors are approximately same as the air quality PM2.5, the sunshine duration, the climate change and the like in the same county area, so the energy efficiency mean value parameter in the user group area which is agreed is used as the comparison reference of the current energy efficiency parameter;
here, the air conditioner packages and sends the energy efficiency parameters to a cloud server erected by an air conditioner service provider to be stored as historical data of the air conditioner; therefore, the energy efficiency average parameter can be calculated by calling historical data of all air conditioner users in the same user group area within a certain period of time.
And S403, if the current energy efficiency parameter is lower than the energy efficiency average value parameter, controlling the air conditioner to start a self-cleaning mode.
According to the control method for self-cleaning of the air conditioner, the starting operation of the self-cleaning mode is intelligently judged and controlled according to the energy efficiency parameters, the user does not need to participate, the air conditioner automatically selects the proper time for starting the self-cleaning mode, the starting accuracy of the self-cleaning mode is improved, and the use experience of the user is guaranteed.
The control method of the present application further includes: and if the current energy efficiency parameter is lower than a preset first parameter threshold value, controlling the air conditioner to start a self-cleaning mode.
Optionally, the first parameter threshold is calculated according to the following formula:
cop1＝A*cope；
where cop1 is the first parameter threshold; a is a first proportional calculation coefficient, and the value range of the first proportional calculation coefficient is 0.55-0.65; the cope is a reference energy efficiency parameter of the air conditioner.
Before the air conditioner leaves the factory, an energy efficiency parameter when the air conditioner operates with a preset reference parameter can be measured through an experiment and the like, and is used as a reference energy efficiency parameter, such as a reference energy efficiency ratio when the air conditioner operates with the preset reference parameter; at the moment, no pollutant is attached to the air conditioner, so the reference energy efficiency parameter can be used for representing the parameter of the heat exchanger in a pollutant-free state; the pollutant attached to the air conditioner can affect the heat exchange efficiency of the heat exchanger, so the pollutant can also affect the actual energy efficiency parameter of the air conditioner, the energy efficiency parameter measured on the heat exchanger attached with the pollutant is different from the benchmark energy efficiency parameter measured on the heat exchanger not attached with the pollutant in value, and therefore the scaling degree of the heat exchanger of the air conditioner is determined according to the comparison result of the current energy efficiency parameter and the preset benchmark energy efficiency parameter.
The more pollutants are attached to the heat exchanger, the greater the difference between the current energy efficiency parameter and the reference energy efficiency parameter is; the fewer pollutants are attached to the heat exchanger, the smaller the temperature difference between the current energy efficiency parameter and the reference energy efficiency parameter is; namely the two are in positive correlation; therefore, the air conditioner can preset the correlation between the comparison result of the current energy efficiency parameter and the preset reference energy efficiency parameter and the scaling degree of the heat exchanger; therefore, after the current energy efficiency parameter of the heat exchanger is obtained, the scaling degree of the heat exchanger of the air conditioner can be determined according to the reference energy efficiency parameter and the preset incidence relation, and then whether the self-cleaning mode of the air conditioner needs to be started or not can be judged.
In this embodiment, the first parameter threshold is an energy efficiency threshold calculated according to a preset proportional calculation coefficient based on a reference energy efficiency parameter; and under the condition that the current energy efficiency parameter is lower than a preset first parameter threshold value, judging that the scaling degree of a heat exchanger of the air conditioner reaches the condition that cleaning and descaling are required, and controlling the air conditioner to start a self-cleaning mode.
Optionally, the air conditioner in step S403 is to interrupt the current heat exchange mode of the air conditioner and forcibly switch to the self-cleaning mode to perform cleaning operation on the air conditioner, and if it is determined that self-cleaning is required through steps S401 to S403 in the process that the air conditioner operates in the cooling mode, the air conditioner is controlled to switch from the cooling mode to the self-cleaning mode; after the self-cleaning operation of the air conditioner is finished, the initial heat exchange mode, i.e., the cooling mode in this example, is switched back again.
Here, the condition for controlling the air conditioner to turn on the self-cleaning mode further includes determining that the person in the indoor environment is in a stationary state and that the body surface temperature is not higher than the set temperature. Because the operation parameters of the air conditioner in the self-cleaning mode are different from the operation parameters set by the air conditioner in the initial heat exchange mode, the temperature and the humidity of the indoor environment can also change in the operation process of the self-cleaning mode, and if the refrigeration mode is interrupted, the temperature of the indoor environment can gradually rise; here, the humiture change of indoor environment can cause the discomfort of the user who is in indoor environment at present, therefore, the air conditioner of this application is when the user of indoor environment is in quiescent condition and body surface temperature is not higher than the settlement temperature operation self-cleaning mode to reduce the air conditioner and operate the direct-viewing influence of self-cleaning mode to user's travelling comfort.
It should be understood that the above description is taking the initial heat exchange mode of the air conditioner as an example of the cooling mode; when the initial heat exchange mode of the air conditioner is the heating mode, the requirement that the body surface temperature is not lower than the set temperature is met, so that the body surface temperature of a user is not reduced too much due to the operation of the self-cleaning mode under the heating working condition.
Therefore, by forcibly switching the operation self-cleaning mode, pollutants such as dust and the like accumulated on the indoor heat exchanger can be prevented from being continuously blown into the indoor environment, so that the physical health of an air conditioner user and the cleanness of the indoor environment are ensured; meanwhile, the self-cleaning operation of the air conditioner can also improve the power consumption state of the air conditioner, and the problems of power consumption increase and energy efficiency reduction caused by excessive pollutants are reduced.
Optionally, the control method of the present invention further includes: and if the current energy efficiency parameter is lower than a preset second parameter threshold and higher than a first parameter threshold, pushing reminding information for starting a self-cleaning mode to a user.
Here, the air conditioner may send a preset reminding message, such as a text or a flash lamp prompting the user to start the self-cleaning mode, through hardware such as a display screen and an indicator lamp of the air conditioner body.
Or, the air conditioner can be in communication connection with a mobile terminal such as a mobile phone of a user through a data network such as a home wifi, and the mobile terminal is provided with an application program and the like provided by a service provider of the air conditioner, so that the air conditioner pushes reminding information for starting the self-cleaning mode to the user by using the application program. Correspondingly, the user can also send instruction information for starting the self-cleaning mode to the air conditioner through the application program, and the air conditioner automatically carries out the self-cleaning mode after receiving the instruction information forwarded by the application program, so that the remote interactive control between the user and an air conditioner product is realized, and the user can also carry out self-cleaning on the air conditioner control under the remote condition.
Optionally, the second parameter threshold is calculated according to the following formula:
cop2＝B*cope；
where cop2 is the second parameter threshold; b is a second proportional calculation coefficient, and the value range of the second proportional calculation coefficient is 0.75-0.85; the cope is a reference energy efficiency parameter of the air conditioner.
Here, the second parameter threshold is greater than the first parameter threshold, so the energy efficiency parameter corresponding to the second parameter threshold is also higher than the energy efficiency parameter corresponding to the first parameter threshold, and the second parameter threshold is used for representing that a structural problem exists on a heat exchanger of the air conditioner, but the physical health of a user and the operation power consumption of the air conditioner do not reach an energy efficiency condition that a self-cleaning mode needs to be forcibly performed.
