[0039] Combination Figure 8 As shown, the embodiment of the present disclosure discloses an air conditioner, including: a water storage box 1 and a water collection chamber 2. The water storage box 1 is used to receive the condensed water flowing down from the heat exchanger, and a second drainage hole 25 is arranged on the bottom of the side of the water storage box 1. The water collection chamber 2 is arranged at the bottom of the water storage box 1, and the water collection chamber 2 includes an incident light source 21 arranged on the side, a first drainage hole 24 arranged on the other side, and a scattered light receiver 22 arranged at the bottom of the water collection chamber 2, and the water collection chamber 2 and the water storage box 1 are connected by an openable cover plate 23. Among them, the incident angle of the incident light source 21 is perpendicular to the side of the water collection chamber 2; the bottom surface of the water storage box 1 is tilted toward the center at a set angle θ until it is connected to the cover plate 23 of the water collection chamber 2, which is conducive to the collection of water; the first drainage hole 24 and the second drainage hole 25 can respectively discharge the condensed water in the water collection chamber 2 and the water storage box 1 through the drainage pipe 26.

[0040] Combination Figure 1 As shown, the embodiment of the present disclosure provides a method for self-cleaning an air conditioner, comprising:

[0041] S01, the air conditioner control cover and the first drain hole are closed.

[0042] S02: The air conditioner obtains the current turbidity of the condensed water in the water collecting chamber.

[0043] S03, when the current turbidity is greater than or equal to the set turbidity, the air conditioner starts the self-cleaning function.

[0044] The air conditioner can obtain the current turbidity of the condensed water in the water collecting chamber by opening the first cover plate and the first drainage hole at set intervals.

[0045] The method for self-cleaning of the air conditioner provided by the embodiment of the present disclosure is used to control the cover plate and the first drain hole to be closed, and obtain the current turbidity of the condensed water in the water collection chamber. When the current turbidity is greater than or equal to the set turbidity, the self-cleaning function is activated. When judging whether the self-cleaning function needs to be activated or deactivated, the turbidity detection process is placed in a closed environment by closing the cover plate and the first drain hole of the water collection chamber, thereby avoiding the influence of external light and environmental parameters, resulting in inaccurate turbidity detection, and thus the self-cleaning function cannot be activated or deactivated in a timely and accurate manner, thereby improving the accuracy of the activation or deactivation of the self-cleaning function of the air conditioner.

[0046] Combination Figure 2 As shown, the embodiment of the present disclosure provides a method for self-cleaning an air conditioner, comprising:

[0047] S01, the air conditioner control cover and the first drain hole are closed.

[0048] S21, the air conditioner turns on the incident light source to irradiate the condensed water in the water collection chamber.

[0049] S22, the air conditioner controls the scattered light receiver to receive the scattered light after being scattered by the incident light source, and determines the intensity of the heat dissipation light.

[0050] S23, the air conditioner determines the current turbidity according to the intensity of the scattered light.

[0051] S03, when the current turbidity is greater than or equal to the set turbidity, the air conditioner starts the self-cleaning function.

[0052] The method for self-cleaning of an air conditioner provided by the embodiment of the present disclosure is adopted. The air conditioner turns on the incident light source to irradiate the condensed water in the water collection chamber, and controls the scattered light receiver to receive the scattered light after the incident light source is scattered, so as to determine the intensity of the heat dissipation light, and finally determines the current turbidity according to the scattered light intensity. Since the turbidity is detected in the closed water collection chamber, the scattered light generated by the incident light source irradiating the condensed water in the water collection chamber will be received by the scattered light receiver without being disturbed by external light, so that the light intensity of the scattered light can be accurately determined. Turbidity is an indicator to measure the degree of light obstruction by suspended particles in the medium. The suspended particles will scatter the incident light in different directions. By measuring the scattered light intensity in the direction perpendicular to the incident light and comparing it with the internal calibration value, the turbidity in the water sample can be calculated, and the final value can be output after linearization processing. For example, the incident light source emits 860nm infrared light perpendicular to the side of the water collection chamber, and the scattered light receiver detects the scattered light intensity in the 90° direction. Finally, the transmitter calculates the current turbidity of the condensed water according to the detected scattered light intensity.

[0053] Optionally, the air conditioner determines the current turbidity according to the scattered light intensity, including: the air conditioner determines the current turbidity corresponding to the scattered light intensity according to a preset first relationship; wherein the scattered light intensity is positively correlated with the current turbidity.

[0054] In this way, the air conditioner determines the current turbidity corresponding to the scattered light intensity according to the preset first relationship, so that the turbidity can match the scattered light intensity, thereby improving the accuracy of turbidity detection.

[0055] Combination Figure 3 As shown, the embodiment of the present disclosure provides a method for self-cleaning an air conditioner, comprising:

[0056] S01, the air conditioner control cover and the first drain hole are closed.

[0057] S02: The air conditioner obtains the current turbidity of the condensed water in the water collecting chamber.

[0058] S31, the air conditioner determines that the current turbidity is greater than or equal to the set turbidity when the current turbidity is greater than or equal to the set turbidity and lasts for a first period of time.

[0059] S03, when the current turbidity is greater than or equal to the set turbidity, the air conditioner starts the self-cleaning function.

[0060] By adopting the method for self-cleaning of the air conditioner provided by the embodiment of the present disclosure, the air conditioner determines that the current turbidity is greater than or equal to the set turbidity when the current turbidity is greater than or equal to the set turbidity and lasts for a first period of time, thereby avoiding errors in the scattered light receiver and improving the accuracy of turbidity detection.

[0061] Optionally, the air conditioner determines the set turbidity according to the following method: the air conditioner obtains indoor environmental parameters and air conditioner operating parameters; the air conditioner determines the set turbidity according to the indoor environmental parameters and the operating parameters; wherein the indoor environmental parameters include indoor particulate matter concentration, and the particulate matter concentration is positively correlated with the set turbidity.

[0062] In this way, since the rate at which dust is generated on the heat exchanger is closely related to the indoor and outdoor environment, and the more dust there is indoors and outdoors, the greater the power of the air conditioner, and the faster the amount of dust on the heat exchanger increases, the air conditioner obtains the indoor environmental parameters and the air conditioner operating parameters, and determines the set turbidity based on the indoor environmental parameters and the operating parameters. The impact of the environment on the rate of increase of dust is fully considered, so that when the environment is bad, the set turbidity is adaptively increased, and by increasing the upper limit of the turbidity judgment of the self-cleaning function, the frequent start and stop of the self-cleaning function can be avoided, thereby saving energy.

[0063] Combination Figure 4 As shown, the embodiment of the present disclosure provides a method for self-cleaning an air conditioner, comprising:

[0064] S01, the air conditioner control cover and the first drain hole are closed.

[0065] S02: The air conditioner obtains the current turbidity of the condensed water in the water collecting chamber.

[0066] S41, when the current turbidity is greater than or equal to the set turbidity, the air conditioner determines the set power according to the current turbidity.

[0067] S42, the air conditioner starts the self-cleaning function according to the set power.

[0068] Among them, the self-cleaning function can be achieved by frosting the heat exchanger first and then defrosting it. For example, the fan can be turned off first, the heating mode is run, the outdoor heat exchanger is frosted, and then the cooling mode is run to defrost the outdoor heat exchanger; or, the fan can be turned off first, the cooling mode is run, the indoor heat exchanger is frosted, and then the heating mode is run to defrost the indoor heat exchanger, thereby achieving self-cleaning of the indoor heat exchanger or the outdoor heat exchanger.

[0069] By adopting the method for self-cleaning of the air conditioner provided in the embodiment of the present disclosure, since the turbidity of condensed water can reflect the degree of dirtiness of the heat exchanger, the air conditioner determines the set power according to the current turbidity when the current turbidity is greater than or equal to the set turbidity, and starts the self-cleaning function according to the set power, which can match the self-cleaning function with the current degree of dirtiness of the heat exchanger, thereby improving the efficiency of self-cleaning.

[0070] Combination Figure 5 As shown, the embodiment of the present disclosure provides a method for self-cleaning an air conditioner, comprising:

[0071] S01, the air conditioner control cover and the first drain hole are closed.

[0072] S02: The air conditioner obtains the current turbidity of the condensed water in the water collecting chamber.

[0073] S03, when the current turbidity is greater than or equal to the set turbidity, the air conditioner starts the self-cleaning function.

[0074] S51, when the turbidity of the air conditioner is less than the set turbidity and lasts for a second time period, the self-cleaning function is turned off.

[0075] By adopting the method for self-cleaning of the air conditioner provided in the embodiment of the present disclosure, the self-cleaning function of the air conditioner is turned off when the turbidity is less than the set turbidity and lasts for a second time period. By continuously detecting the turbidity within the second time period, the situation in which the self-cleaning function is mistakenly turned off due to turbidity detection error at a certain moment is avoided, thereby improving the accuracy of turning off the self-cleaning function of the air conditioner.
