Referring to fig. 6 in combination, according to an embodiment of the present application, the method for detecting dirty filter screen of a panel assembly includes: acquiring the illumination intensity C1 of the external natural light; detecting whether the illumination intensity of the external natural light reaches a set value; when the light does not reach the set value, controlling the light-emitting device to emit light; acquiring illumination intensity C3 of the light-emitting device; acquiring the illumination intensity C4 of the light-emitting device after passing through the filter screen 3; acquiring the light intensity transmittance CT1, wherein CT1 is C4/C3; and judging whether the filter screen 3 is dirty or not according to the CT 1.

According to the filter screen filth blockage detection method, when natural light is insufficient, the light emitting device on the inner side of the filter screen 3 is used for emitting light, light for detecting filth blockage of the filter screen is complemented, and accuracy and reliability of a filth blockage detection result of the filter screen are guaranteed.

In addition, this filter screen filth blocks up detection method is before complementing light through illuminator, can detect the illumination intensity of natural light earlier, if the illumination intensity of natural light reaches the setting value, can satisfy filter screen 3 dirty stifled detection requirement, then just can directly utilize the natural light to detect filter screen 3 dirty stifled this moment, need not to open illuminator, only when the illumination intensity that detects the natural light is unsatisfied with the detection demand, just can open illuminator and detect filter screen 3 dirty stifled, therefore the detection mode is more nimble, can satisfy the filter screen filth under the different illumination condition and block up the detection demand, and the testing result is accurate reliable.

In one embodiment, the step of determining whether the filter screen 3 is dirty according to CT1 includes: if the CT1 is less than a, judging that the filter screen 3 is dirty and blocked and needs to be cleaned; if a is less than or equal to CT1 and less than or equal to b, judging that the filter screen 3 is slightly dirty and blocked without cleaning; if CT1 is greater than b, it is determined that filter screen 3 is not dirty.

The dirty stifled condition of filter screen 3 can be graded to above-mentioned mode to confirm that filter screen 3 does not take place dirty stifled, has dirty stifled but does not influence the use or dirty stifled serious needs wash, consequently can accurately judge the dirty stifled condition of filter screen 3, and then guarantee the timely washing of filter screen 3.

In some embodiments, a filth blockage indicator lamp can be added, and the filth blockage indicator lamp can show different colors according to the size of the detected CT1, so that the severity of the current filth blockage condition of the filter screen 3 is prompted, and meanwhile, a user can automatically select whether to clean the filter screen 3 according to the severe program of the filth blockage condition, so that the operability is stronger, and the flexibility is higher. The filth blockage indicating lamp can define the filth blockage condition of the filter screen 3 according to the sequence of red, orange, yellow, green, indigo and purple, and the filth blockage condition of the filter screen 3 is weakened in sequence according to the sequence from red to purple.

The values of a, b and c are constants, can be set when the air conditioner leaves a factory, can be set by a user, can be determined by the self-learning capability of the air conditioner, and can be obtained through experiments.

The step of judging whether the filter screen 3 is dirty or not according to the CT1 further comprises the following steps: when the filter screen 3 is judged to be dirty and blocked and needs to be cleaned, the alarm is controlled to give an alarm, so that the user is reminded that the filter screen 3 is dirty and blocked and needs to be cleaned.

The filter screen filth blockage detection method also comprises the following steps: when the illumination intensity of the external natural light reaches a set value, acquiring the illumination intensity C2 of the external natural light after penetrating through the filter screen 3; acquiring the light intensity transmittance CT2, wherein CT2 is C2/C1; and judging whether the filter screen 3 is dirty or not according to the CT 2.

Because filter screen 3 does not take place filthy stifled, perhaps when filthy stifled condition is slight, filter screen 3's light passes through the condition better, the illumination intensity transmissivity also can be higher, when filthy stifled condition is serious, the light that will lead to filter screen 3 passes through the condition relatively poor, the illumination intensity transmissivity also can be lower, therefore, as long as light is enough, the ratio through the illumination intensity of the inside and outside both sides that detect filter screen 3, just can accurately judge filter screen 3's filthy stifled condition, and need not to contrast illumination intensity one by one, it is more nimble convenient to detect.

In an embodiment, the light emitting device may be disposed outside the filter screen 3, so that when the natural light is insufficient, the user may open the light emitting device outside or inside the filter screen 3 as needed to detect the filth blockage degree of the filter screen 3, and in addition, the problem that the filth blockage degree of the filter screen 3 cannot be detected when one of the light emitting devices is damaged can be prevented, thereby improving the reliability of filth blockage detection of the filter screen 3.

The step of judging whether the filter screen 3 is dirty or not according to the CT2 comprises the following steps: if the CT2 is less than a, judging that the filter screen 3 is dirty and blocked and needs to be cleaned; if a is less than or equal to CT2 and less than or equal to b, judging that the filter screen 3 is slightly dirty and blocked without cleaning; if CT2 is greater than b, it is determined that filter screen 3 is not dirty.

It is readily understood by a person skilled in the art that the advantageous ways described above can be freely combined, superimposed without conflict.
