DETAILED DESCRIPTION OF THE EMBODIMENTS

[0035] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions in the present invention will be clearly and completely described below with reference to the accompanying drawings in the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present invention without making creative efforts fall within the protection scope of the present invention.

[0036] The following will describe Figures 1 - 5 the air conditioner dust accumulation detection method, device, air conditioner, and electronic device of the present invention.

[0037] As Figure 1 shown, the present invention provides an air conditioner dust accumulation detection method, including:

[0038] Step 110: Obtain a first temperature value at a first temperature coil and a second temperature value at a second temperature coil.

[0039] Wherein, the first temperature coil is fixed above the air conditioner air inlet (on the wall side), and the second temperature coil is fixed below the air conditioner air inlet (away from the wall side).

[0040] It can be understood that a temperature detector is provided in the temperature coil, and temperature data can be collected through the temperature detector.

[0041] The first temperature coil and the second temperature coil can respectively collect the temperatures of two different heat exchange circuits of the air conditioner.

[0042] Step 120: Determine the dust accumulation state of the air conditioner based on the absolute value of the difference between the first temperature value and the second temperature value.

[0043] It can be understood that based on the absolute value of the difference between the first temperature value and the second temperature value, it can be determined whether the air conditioner filter has dust accumulation. If the absolute value of the difference between the first temperature value and the second temperature value is larger, it means that the dust accumulation on the air conditioner filter is more. On the contrary, if the absolute value of the difference between the first temperature value and the second temperature value is smaller, it means that the dust accumulation on the air conditioner filter is less.

[0044] In some embodiments, in the air conditioner dust accumulation detection method provided by the present invention, as Figure 2 shown, the first temperature coil 210 is fixed above the air conditioner air inlet (on the wall side), the second temperature coil 220 is fixed below the air conditioner air inlet (away from the wall side), and fins 240 are on the left side of the first temperature coil 210 and the second temperature coil 220. A heat exchange tube 230 protrudes on the right side of the air conditioner.

[0045] Further, as Figure 3As shown, the first temperature coil 210 and the second temperature coil 220 are respectively fixed on the cross pipes 260 on both sides of the tube sheet 250, that is, the first temperature coil 210 and the second temperature coil 220 are respectively fixed on the cross pipes 260 of two different heat exchange circuits of the air conditioner.

[0046] The present invention mainly utilizes that the dust accumulation starts from the side of the air conditioner against the wall and accumulates outward. The uneven dust accumulation will cause the heat exchange of the entire evaporator to become uneven gradually. The temperature at the first temperature coil will be lower and lower than the temperature at the second temperature coil as the dust accumulation increases. By using the temperature difference between the two, it can play a role in detecting the degree of dust accumulation and prompting the user of the degree of dust accumulation.

[0047] In some embodiments, determining the dust accumulation state of the air conditioner based on the absolute value of the difference between the first temperature value and the second temperature value includes:

[0048] When the absolute value of the difference between the first temperature value and the second temperature value is greater than the first temperature threshold, it is determined that the air conditioner has dust accumulation.

[0049] It can be understood that the first temperature threshold can be set according to the actual working conditions of the air conditioner. For different air conditioners or different environments, the first temperature threshold can be different. For example, when the temperature difference fluctuation range between the first coil and the second coil during normal use is 2°C, the first temperature threshold can be set to 2°C. When the absolute value of the difference between the first temperature value and the second temperature value is greater than 2°C, it is determined that the air conditioner has dust accumulation. Specifically, it can be determined that there is dust accumulation on the filter net of the air conditioner. When the absolute value of the difference between the first temperature value and the second temperature value is less than or equal to 2°C, it is determined that the air conditioner has no dust accumulation.

[0050] Furthermore, after determining that the air conditioner has dust accumulation, control the dust cleaning fan arranged in the air conditioner to work so as to blow away the dust accumulation on the filter net of the air conditioner.

[0051] In some embodiments, the air conditioner dust accumulation detection method further includes:

[0052] When the absolute value of the difference between the first temperature value and the second temperature value is less than or equal to the second temperature threshold and greater than the first temperature threshold, control the air conditioner to operate normally;

[0053] When the absolute value of the difference between the first temperature value and the second temperature value is greater than the second temperature threshold, control the air conditioner to suspend operation.

[0054] It can be understood that the second temperature threshold can be 6°C.

[0055] When the absolute value of the difference between the first temperature value and the second temperature value is less than or equal to the second temperature threshold and greater than the first temperature threshold, it can be determined that the air conditioner has mild or moderate dust accumulation. At this time, the air conditioner can be controlled to operate normally. The air conditioner will operate in the same way as it did before detecting mild or moderate dust accumulation, without changing its operating state.

[0056] When the absolute value of the difference between the first temperature value and the second temperature value is greater than the second temperature threshold, it can be determined that the air conditioner has severe dust accumulation, and the operation of the air conditioner needs to be paused so that the user can perform maintenance and inspection on the air conditioner to avoid greater failures of the air conditioner.

[0057] In some embodiments, the air conditioner dust accumulation detection method further includes:

[0058] When the absolute value of the difference between the first temperature value and the second temperature value is greater than the second temperature threshold, control the first warning light to emit a warning.

[0059] It can be understood that when the absolute value of the difference between the first temperature value and the second temperature value is greater than the second temperature threshold, it is determined that the air conditioner has severe dust accumulation, and the dust cleaning red light is controlled to turn on to prompt the user to clean the dust.

[0060] In some embodiments, the air conditioner dust accumulation detection method further includes:

[0061] When the absolute value of the difference between the first temperature value and the second temperature value is greater than the first temperature threshold and less than or equal to the third temperature threshold, control the second warning light to emit a warning;

[0062] When the absolute value of the difference between the first temperature value and the second temperature value is greater than the third temperature threshold and less than or equal to the second temperature threshold, control the third warning light to emit a warning.

[0063] It can be understood that when the absolute value of the difference between the first temperature value and the second temperature value is greater than the first temperature threshold and less than or equal to the third temperature threshold, it is determined that the air conditioner has mild dust accumulation, and the dust cleaning green light is controlled to turn on to remind the user.

[0064] When the absolute value of the difference between the first temperature value and the second temperature value is greater than the third temperature threshold and less than or equal to the second temperature threshold, it is determined that the air conditioner has moderate dust accumulation, and the dust cleaning yellow light is controlled to turn on to remind the user.

[0065] The user is reminded of the current dust accumulation level of the air conditioner through lights of different colors so that the user can choose corresponding treatment methods.

[0066] In summary, the air conditioner dust accumulation detection method provided by the present invention includes: obtaining a first temperature value at a first temperature coil and a second temperature value at a second temperature coil; determining the dust accumulation state of the air conditioner based on the absolute value of the difference between the first temperature value and the second temperature value; wherein, the first temperature coil is fixed above the air inlet of the air conditioner, and the second temperature coil is fixed below the air inlet of the air conditioner.

[0067] In the air conditioner dust accumulation detection method provided by the present invention, the temperature above the air inlet of the air conditioner and the temperature below the air inlet of the air conditioner are respectively collected by the first temperature coil and the second temperature coil. Dust accumulation starts from the side of the air conditioner against the wall and accumulates outward. Uneven dust accumulation will cause the heat exchange of the entire evaporator to become uneven gradually. The temperature at the point of the first temperature coil will be lower and lower than the temperature at the second temperature coil as the dust accumulation increases. Therefore, based on the absolute value of the temperature difference between the first temperature coil and the second temperature coil, the dust accumulation situation inside the air conditioner can be determined.
