The embodiment of the disclosure provides a method for self-cleaning of an air conditioner.
Fig. 1 is a schematic flow chart of a method for self-cleaning of an air conditioner according to an embodiment of the disclosure.
In this embodiment, a method for air conditioning self-cleaning, includes:
and S101, controlling the air conditioner to operate in a degreasing mode.
The oil stain is usually closely attached to the surface of the heat exchanger, and in order to remove the oil stain on the surface of the heat exchanger of the air conditioner, the oil stain can be firstly emulsified or dissolved, so that the oil stain can not be closely attached to the surface of the heat exchanger, then the heat exchanger is washed, and the emulsified or dissolved oil stain is carried away from the surface of the heat exchanger. In some application scenes, when the air conditioner receives a self-cleaning signal, the current oil stain amount of the surface of the heat exchanger is obtained, and when the current oil stain amount is larger than or equal to the set oil stain amount, the air conditioner is controlled to operate in an oil stain removing mode.
And S102, when the current oil stain amount on the surface of the heat exchanger is smaller than the set oil stain amount, controlling the air conditioner to operate in a dust removal mode.
In order to obtain the size relation between the current oil stain amount and the set oil stain amount, an image of the heat exchanger can be obtained through a camera device, the oil stain area on the surface of the heat exchanger in the image is identified, the current oil stain amount is represented by the oil stain area, the set oil stain amount is represented by the set area, the size relation between the oil stain area and the set area is judged, and when the oil stain area is smaller than the set area, the current oil stain amount can be determined to be smaller than the set oil stain amount; when the oil stain area is larger than or equal to the set oil stain area, the current oil stain amount can be determined to be larger than or equal to the set oil stain amount, and at the moment, the air conditioner is controlled to continuously operate in an oil stain removing mode, so that the oil stain on the surface of the heat exchanger is better cleaned.
The oil stain on the surface of the heat exchanger is cleaned firstly, and then the dust on the surface of the heat exchanger is cleaned, so that the oil stain and the dust attached to the surface of the heat exchanger can be cleaned, and the self-cleaning effect of the air conditioner is improved.
The heat exchanger in the embodiment of the present disclosure refers to a heat exchanger to be cleaned, which may be an indoor heat exchanger or an outdoor heat exchanger. When the heat exchanger is an indoor heat exchanger, the method for self-cleaning the air conditioner can clean the indoor heat exchanger; when the heat exchanger is an outdoor heat exchanger, the method for self-cleaning the air conditioner can clean the outdoor heat exchanger.

Fig. 2 is a schematic flowchart illustrating a process for controlling an air conditioner to operate in a degreasing mode according to an embodiment of the present disclosure.
In this embodiment, controlling the air conditioner to operate in the degreasing mode includes:
and S201, reducing the temperature of the heat exchanger to enable the temperature of the heat exchanger to be less than or equal to the dew point temperature, and increasing the ventilation volume of the heat exchanger to enable the surface of the heat exchanger to be condensed.
When the heat exchanger is an indoor heat exchanger, controlling the air conditioner to enter a refrigeration mode, reducing the opening degree of an expansion valve and reducing the temperature of the indoor heat exchanger; or, the running frequency of the compressor is increased, and the temperature of the indoor heat exchanger is reduced; or, the opening degree of the expansion valve is reduced, the running frequency of the compressor is increased, and the temperature of the indoor heat exchanger is reduced. When the heat exchanger is an outdoor heat exchanger, controlling the air conditioner to enter a heating mode, reducing the opening degree of an expansion valve and reducing the temperature of the outdoor heat exchanger; or, the running frequency of the compressor is increased, and the temperature of the outdoor heat exchanger is reduced; or, the opening degree of the expansion valve is reduced, the running frequency of the compressor is increased, and the temperature of the outdoor heat exchanger is reduced.
In order to increase the ventilation quantity of the heat exchanger, the rotating speed of a side fan of the heat exchanger can be increased; alternatively, the time that the heat exchanger is maintained at less than or equal to the dew point temperature may be increased. When the heat exchanger is an indoor heat exchanger, the heat exchanger side fan is an indoor fan; when the heat exchanger is an outdoor heat exchanger, the heat exchanger side fan is an outdoor fan. The ventilation quantity of the heat exchanger is increased, the amount of water vapor which can be contacted with the heat exchanger is increased, the condensation quantity of the heat exchanger is increased, and the condensation is convenient for washing the oil stains and the cleaning agent which are emulsified/dissolved on the heat exchanger.
Step S202, spraying a cleaning agent on the surface of the heat exchanger, and increasing the temperature of the heat exchanger to enable the temperature of the heat exchanger to be a preset temperature.
The air conditioner indoor unit is provided with a cleaning agent storage device, a pressurizing device, a conveying pipe and a nozzle, wherein the pressurizing device provides pressure for the cleaning agent storage device, or the pressurizing device extracts the cleaning agent in the cleaning agent storage device, so that the cleaning agent is conveyed to the nozzle through the conveying pipe, and the nozzle sprays the cleaning agent onto the surface of the heat exchanger; similarly, when the heat exchanger is an outdoor heat exchanger, the outdoor unit of the air conditioner is provided with a detergent storage device, a pressure boosting device, a delivery pipe, a nozzle, and the like.
When the heat exchanger is an indoor heat exchanger, controlling the air conditioner to enter a heating mode, reducing the opening degree of an expansion valve and increasing the temperature of the indoor heat exchanger; or, the running frequency of the compressor is increased, and the temperature of the indoor heat exchanger is increased; or, the opening degree of the expansion valve is reduced, the running frequency of the compressor is increased, and the temperature of the indoor heat exchanger is increased. When the heat exchanger is an outdoor heat exchanger, controlling the air conditioner to enter a refrigeration mode, reducing the opening degree of an expansion valve and increasing the temperature of the outdoor heat exchanger; or, the running frequency of the compressor is increased, and the temperature of the outdoor heat exchanger is increased; or, the opening degree of the expansion valve is reduced, the running frequency of the compressor is increased, and the temperature of the outdoor heat exchanger is increased.
The predetermined temperature is a temperature at which the cleaning agent is used, and may be 30 to 70 ℃, for example, any one of 30 ℃, 40 ℃, 50 ℃, 60 ℃ and 70 ℃. Under the preset temperature, the cleaning agent has good cleaning effect on oil stains on the heat exchanger.
And S203, increasing the rotating speed of a side fan of the heat exchanger after the heat exchanger maintains the preset temperature for the preset time.
The process of emulsifying or dissolving the oil stain by the cleaning agent needs a certain time, after the preset time, the cleaning agent can be judged to emulsify or dissolve the oil stain, for example, under the condition that the time for maintaining the preset temperature of the heat exchanger is more than or equal to the preset time, the oil stain is determined to be stripped from the surface of the heat exchanger, at the moment, the rotating speed of a side fan of the heat exchanger can be increased, and the emulsified oil stain or the dissolved oil stain is carried away from the surface of the heat exchanger by using the condensation. Optionally, the preset time may be 0.5min to 5min, for example, the preset time may be 0.5min, 1min, 2min, 3min, 4min or 5 min.
In the prior art, oil stains on a heat exchanger are usually removed at high temperature, and the required temperature is higher when the oil stains are removed; in the common sense of life, although the cleaning agent can be manually used for removing the greasy dirt on some metal surfaces, the process of automatically removing the greasy dirt on the heat exchanger of the air conditioner by using the cleaning agent faces practical difficulties. For example, in the process of manually removing oil stains, after a cleaning agent is sprayed on a metal surface, the cleaning agent needs to be manually wiped, but in the process of automatically cleaning the air-conditioning heat exchanger, the cleaning agent on the surface of the heat exchanger is difficult to automatically wipe. In the embodiment, the cleaning agent can be automatically sprayed to the heat exchanger, after the preset time, the rotating speed of the side fan of the heat exchanger is increased, the emulsified oil stain or the dissolved oil stain is carried away from the surface of the heat exchanger by using the condensation, and the technical effect of removing the oil stain at a lower temperature is realized.
Optionally, when the current oil stain amount on the surface of the heat exchanger is smaller than the set oil stain amount, the air conditioner is controlled to operate in the dust removal mode according to the size relationship between the current ash deposition amount on the surface of the heat exchanger and the set ash deposition amount.
In order to obtain the current amount of ash deposition, the distance between the fixed position and the heat exchanger can be measured, for example, by using infrared rays, the fixed position can be the installation position of an infrared ray measuring device, and the distance is used for representing the current amount of ash deposition on the surface of the heat exchanger: the larger the distance is, the larger the current ash deposition amount on the surface of the heat exchanger is; alternatively, the distance between two heat exchanger fins can be measured and then used to represent the current amount of ash deposition on the heat exchanger surface: the greater this distance, the greater the current amount of ash deposition on the heat exchanger surface. When the current amount of soot is represented by the distance between the fixed position and the heat exchanger or the distance between two fins of the heat exchanger, the set amount of soot is correspondingly represented by one set distance. For example, when the distance between the fixed position and the heat exchanger or the distance between two fins of the heat exchanger is smaller than the set distance, determining that the current soot deposition amount is smaller than the set soot deposition amount; and when the distance between the fixed position and the heat exchanger or the distance between two fins of the heat exchanger is greater than or equal to the set distance, determining that the current ash deposition amount is greater than or equal to the set ash deposition amount.
In some application scenes, the set ash deposition amount is a standard which is required to be met by the self-cleaning of the air conditioner, when the current ash deposition amount is greater than or equal to the set ash deposition amount, the self-cleaning of the air conditioner is determined not to reach the standard, the air conditioner is controlled to operate in a dust removal mode, and the self-cleaning process is continued; and when the current dust deposition amount is less than the set dust deposition amount, determining that the self-cleaning of the air conditioner reaches the standard, controlling the air conditioner not to enter a dust removal mode any more, and interrupting the self-cleaning process.
In some application scenes, the set ash deposition amount is an index for selecting a dust removal mode, when the current ash deposition amount is greater than or equal to the set ash deposition amount, the ash deposition amount on the surface of the heat exchanger is confirmed to be larger, and the air conditioner is controlled to enter the frosting-defrosting dust removal mode; and when the current accumulated dust amount is smaller than the set accumulated dust amount, confirming that the accumulated dust amount on the surface of the heat exchanger is smaller, and controlling the air conditioner to enter a condensation-dew removal dust removal mode.
Fig. 3 is a schematic flowchart illustrating a process of controlling an air conditioner to operate in a dust removal mode according to an embodiment of the present disclosure.
In this embodiment, when the current soot deposition amount is greater than or equal to the set soot deposition amount, controlling the air conditioner to operate in the dust removal mode includes:
and S301, reducing the temperature of the heat exchanger to enable the temperature of the heat exchanger to be less than or equal to the frost point temperature.
When the heat exchanger is an indoor heat exchanger, controlling the air conditioner to enter a refrigeration mode, reducing the opening degree of an expansion valve and reducing the temperature of the indoor heat exchanger; or, the running frequency of the compressor is increased, and the temperature of the indoor heat exchanger is reduced; or, the opening degree of the expansion valve is reduced, the running frequency of the compressor is increased, and the temperature of the indoor heat exchanger is reduced. When the heat exchanger is an outdoor heat exchanger, controlling the air conditioner to enter a heating mode, reducing the opening degree of an expansion valve and reducing the temperature of the outdoor heat exchanger; or, the running frequency of the compressor is increased, and the temperature of the outdoor heat exchanger is reduced; or, the opening degree of the expansion valve is reduced, the running frequency of the compressor is increased, and the temperature of the outdoor heat exchanger is reduced.
Before step S301, a condensation phase is further included, for example: and reducing the temperature of the heat exchanger to make the temperature of the heat exchanger less than or equal to the dew point temperature, and increasing the ventilation volume of the heat exchanger to make the surface of the heat exchanger condensed.
And S302, after the surface of the heat exchanger is frosted, increasing the temperature of the heat exchanger to defrost the surface of the heat exchanger.
When the heat exchanger is an indoor heat exchanger, controlling the air conditioner to enter a heating mode, reducing the opening degree of an expansion valve and increasing the temperature of the indoor heat exchanger; or, the running frequency of the compressor is increased, and the temperature of the indoor heat exchanger is increased; or, the opening degree of the expansion valve is reduced, the running frequency of the compressor is increased, and the temperature of the indoor heat exchanger is increased. When the heat exchanger is an outdoor heat exchanger, controlling the air conditioner to enter a refrigeration mode, reducing the opening degree of an expansion valve and increasing the temperature of the outdoor heat exchanger; or, the running frequency of the compressor is increased, and the temperature of the outdoor heat exchanger is increased; or, the opening degree of the expansion valve is reduced, the running frequency of the compressor is increased, and the temperature of the outdoor heat exchanger is increased.
When the current ash deposition amount on the surface of the heat exchanger is larger, for example, the current ash deposition amount is larger than or equal to the set ash deposition amount, a self-cleaning mode of frosting and defrosting is adopted, and a better cleaning effect can be realized.
Steps S301 and S302 show steps indispensable in the frosting-defrosting dust removal mode, optionally, one or more cycles of the frosting-defrosting dust removal mode may be performed, for example, 1 cycle, 2 cycles, 3 cycles, 4 cycles, 5 cycles or more cycles of the frosting-defrosting dust removal mode may be performed to improve the self-cleaning effect, and after the frosting-defrosting dust removal mode is completed, the condensation-dew removal dust removal mode may be continuously performed to further improve the self-cleaning effect. Alternatively, after step S302 is performed, the current soot deposition amount is obtained, step S301 is performed when the current soot deposition amount is greater than or equal to the set soot deposition amount, and the condensation-dew removal dust removal mode is performed when the current soot deposition amount is less than the set soot deposition amount, so that the self-cleaning effect can be improved.
Fig. 4 is a schematic flowchart illustrating a process of controlling an air conditioner to operate in a dust removal mode according to an embodiment of the present disclosure.
In this embodiment, when the current soot deposition amount is less than the set soot deposition amount, controlling the air conditioner to operate in the dust removal mode includes:
and S401, reducing the temperature of the heat exchanger to enable the temperature of the heat exchanger to be less than or equal to the dew point temperature, and increasing the ventilation volume of the heat exchanger to enable the surface of the heat exchanger to be condensed.
When the heat exchanger is an indoor heat exchanger, controlling the air conditioner to enter a refrigeration mode, reducing the opening degree of an expansion valve and reducing the temperature of the indoor heat exchanger; or, the running frequency of the compressor is increased, and the temperature of the indoor heat exchanger is reduced; or, the opening degree of the expansion valve is reduced, the running frequency of the compressor is increased, and the temperature of the indoor heat exchanger is reduced. When the heat exchanger is an outdoor heat exchanger, controlling the air conditioner to enter a heating mode, reducing the opening degree of an expansion valve and reducing the temperature of the outdoor heat exchanger; or, the running frequency of the compressor is increased, and the temperature of the outdoor heat exchanger is reduced; or, the opening degree of the expansion valve is reduced, the running frequency of the compressor is increased, and the temperature of the outdoor heat exchanger is reduced.
And S402, increasing the rotating speed of a fan on the side of the heat exchanger after the surface of the heat exchanger is condensed.
When the current accumulated dust amount on the surface of the heat exchanger is small, for example, the current accumulated dust amount is smaller than the set accumulated dust amount, a condensation-dew removal dust removal mode is adopted, so that a better cleaning effect can be realized, and energy is saved.
Steps S401 and S402 show the condensation-dewfall dust removal mode, and optionally, the condensation-dewfall dust removal mode may be performed for one or more cycles, for example, the condensation-dewfall dust removal mode may be performed for 1 cycle, 2 cycles, 3 cycles, 4 cycles, 5 cycles, or more cycles, to improve the self-cleaning effect. Optionally, after step S402 is executed, the current soot deposition amount is obtained, and when the current soot deposition amount is greater than or equal to the standard of the self-cleaning requirement of the air conditioner, that is, the self-cleaning of the air conditioner does not reach the standard, step S401 is continuously executed, so as to improve the self-cleaning effect; when the current dust deposition is smaller than the standard of the self-cleaning requirement of the air conditioner, namely the self-cleaning of the air conditioner reaches the standard, the air conditioner can be controlled to exit the self-cleaning mode.
In the foregoing method for self-cleaning of the air conditioner, the air conditioner needs to be switched from a cooling mode to a heating mode, or the air conditioner needs to be switched from the heating mode to the cooling mode. In some application scenarios, the four-way valve rapid reversing technology can be used for switching the air conditioner between the cooling mode and the heating mode. When the air conditioner is switched between the refrigeration mode and the heating mode, the running frequency of the compressor is reduced firstly, then the four-way valve is controlled to change direction quickly, finally the running frequency of the compressor is improved, and the air conditioner can be switched between the refrigeration mode and the heating mode without stopping.
