In the embodiment of the present disclosure, the indoor fan of the air conditioner is an axial flow fan, the air flow thereof is in the same direction as the axis of the fan blade, and the gas flows parallel to the axis of the fan. During the reversal process of the axial flow fan, a certain amount of heat will be released, which will make the ambient temperature rise appropriately.

With reference to FIG. 1 , an embodiment of the present disclosure provides a control method for anti-condensation of an air conditioner, including the following steps:

S101: Obtain the ambient temperature at the air deflector of the air conditioner and the air deflector temperature of the air deflector when the air conditioner is in cooling operation.

Temperature sensors are respectively provided on the air conditioner near the air guide plate and on the air guide plate of the air conditioner to detect the ambient temperature at the air guide plate and the temperature of the air guide plate (ie, the temperature of the air guide plate panel).

S102: When the ambient temperature is greater than the temperature of the air deflector, control the indoor fan of the air conditioner to reverse rotation to reduce the degree of condensation on the air deflector.

Optionally, when the ambient temperature is greater than the temperature of the air deflector, controlling the indoor fan of the air conditioner to reverse to reduce the degree of condensation on the air deflector includes: obtaining a temperature difference between the ambient temperature and the temperature of the air deflector; When the temperature difference is greater than or equal to the first preset temperature difference and smaller than the second preset temperature difference, after the indoor fan is controlled to run normally for the first period of time, the indoor fan is controlled to run in reverse for the second period of time; When the value is greater than the second preset temperature difference, the indoor fan is controlled to run in reverse for a third duration; wherein, the first preset temperature difference is less than the second preset temperature difference, the first duration is greater than the second duration, and the first duration is greater than the second duration. The second period is longer than the third period.

The value range of the first preset temperature difference is [2°C, 5°C], for example, 2°C, 3°C, 4°C, and 5°C, and the value range of the second preset temperature difference is [6°C, 9°C], for example, 6°C, 7°C, 8°C, 9°C. The value of the first duration is [20min, 30min], for example, 20min (minutes), 25min, 30min, the value of the second duration is [4min, 6min], for example, 4min, 5min, 6min, the third duration is The value is [1min, 3min], eg, 1min, 2min, 3min. When the temperature difference between the ambient temperature and the air deflector temperature is between the first preset temperature difference and the second preset temperature difference, first control the indoor fan to run normally for the first time to form a relatively stable sheet flow, and then control the The indoor fan runs in the reverse direction for the second time, causing the airflow to reverse, which can take away the moisture of the air deflector and reduce the possibility of water droplets caused by condensation on the air deflector; the temperature difference between the ambient temperature and the air deflector temperature is greater than When the second preset temperature difference is used, the indoor ambient temperature is relatively high at this time, and it is only necessary to control the indoor fan to reversely run for a second time to evaporate the water droplets well and avoid the condensation of the wind deflector to form water droplets.

Optionally, the reversal duration of the indoor fan and the temperature difference between the ambient temperature and the air deflector temperature satisfy the following relationship:

Wherein, t is the reversal duration, t ₀ is the preset reversal duration, Δt is the reversal duration compensation value, ΔT is the temperature difference between the ambient temperature and the air deflector temperature, and ΔT ₀ is the preset temperature difference.

When the ambient temperature is greater than the temperature of the air deflector, the greater the temperature difference between the ambient temperature and the air deflector, the easier it is to form condensation on the air deflector, but the time required for the indoor fan to reverse operation to evaporate water droplets will also be shorter. Therefore, the reversal duration of the indoor fan is determined according to the relationship between the above-mentioned reversal duration of the indoor fan and the temperature difference, which can well avoid the condensation of the wind deflector and the formation of water droplets. It will cause damage to the indoor fan.

By using the control method for anti-condensation of the air conditioner provided by the embodiment of the present disclosure, in the case of the air conditioner cooling operation, the ambient temperature at the air deflector of the air conditioner, and the air deflector temperature of the air deflector are obtained, and the ambient temperature is obtained. When the temperature of the air deflector is higher than that of the air deflector, the indoor fan of the air conditioner is controlled to reverse to reduce the degree of condensation on the air deflector. In this way, when the ambient temperature is greater than the temperature of the air deflector, that is, under the environmental conditions where the air deflector is easy to condense, the indoor fan can be reversed and heated to control the reversal of the indoor fan and reduce the ambient humidity near the air deflector. , and accelerate the evaporation of condensation at the air deflector, which can better avoid the problem of water droplets caused by condensation on the air deflector, without adding additional air conditioning components, and the cost is lower.

In some embodiments, controlling the reversal of the indoor fan of the air conditioner includes: obtaining the ambient humidity at the air deflector and the operating frequency of the compressor of the air conditioner; and determining the indoor fan according to the humidity of the ambient humidity and the frequency of the operating frequency Reversal speed; control the indoor fan to reverse according to the reversal speed.

Since the condensation on the air deflector is mainly formed by the moisture in the environment near the air deflector, the ambient humidity at the air deflector easily affects the degree of condensation on the air deflector; and the operating frequency of the air conditioner compressor determines the degree of cooling of the air conditioner , it will also indirectly affect the temperature of the air deflector panel, thereby affecting the condensation degree of the air deflector. Therefore, the reversal speed of the indoor fan can be jointly determined according to the ambient humidity at the air deflector and the operating frequency of the compressor of the air conditioner, which can better achieve the anti-condensation effect of the air conditioner.

Optionally, determine the reversal speed of the indoor fan according to the humidity of the ambient humidity and the frequency of the operating frequency, including: when the ambient humidity is greater than or equal to the preset humidity, and the operating frequency is greater than the first operating frequency or less than the second operating frequency. In the case of the operating frequency, the reversing speed is determined as the first rotation speed; in the case that the ambient humidity is greater than or equal to the preset humidity, and the operating frequency is greater than or equal to the second frequency and less than or equal to the first operating frequency, the reversing speed is determined is the second rotation speed; when the ambient humidity is less than the preset humidity, the reversing speed is determined to be the third rotation speed; wherein, the first operating frequency is greater than the second operating frequency, the first rotating speed is greater than the second rotating speed, and the second rotating speed is greater than third speed.

Optionally, the value range of the preset humidity is [55%, 65%], for example, 55%, 60%, 65%, and the value range of the first operating frequency is [0.8F, F], for example, 0.8 F, 0.9F, F, the value range of the second operating frequency is [0.4F, 0.6F], for example, 0.4F, 0.5F, 0.6F, the value range of the first speed is [0.8R, R], For example, 0.8R, 0.9R, R, the value range of the second speed is [0.5R, 0.7R], for example, 0.5R, 0.6R, 0.7R, the value range of the third speed is [0.2R, 0.4 R], eg, 0.2R, 0.3R, 0.4R. Here, F is the maximum allowed operating frequency of the air-conditioning compressor, and R is the maximum allowed reverse speed of the air-conditioning indoor fan.

When the ambient humidity is greater than or equal to the preset humidity, and the operating frequency of the compressor is greater than the first operating frequency, the room is under high load heat exchange, the indoor humidity and ambient temperature heat exchange are always relatively high, and the indoor fan reverses at high speed ; When the ambient humidity is greater than or equal to the preset humidity, and the operating frequency of the compressor is less than the second operating frequency, the indoor fan will reverse at a high speed and run for a short time to achieve the dew removal effect; when the ambient humidity is greater than or equal to the preset humidity, and When the operating frequency is greater than or equal to the second frequency and less than or equal to the first operating frequency, the indoor fan maintains a medium-speed reversal, which can achieve a better anti-condensation effect; when the ambient humidity is less than the preset humidity, the air deflector The moisture content of the indoor fan is low, and the condensation generation conditions are poor, and the indoor fan can be reversed at a low speed to achieve a better anti-condensation effect.

Since the condensation on the air deflector is mainly formed by the moisture in the environment near the air deflector, the ambient humidity at the air deflector can easily affect the degree of condensation on the air deflector; and the moisture in the air is easily encountered in a low-pressure environment. Condensation forms condensation; the operating frequency of the air conditioner compressor determines the degree of cooling of the air conditioner, which also indirectly affects the temperature of the air deflector panel, thereby affecting the degree of condensation on the air deflector. Therefore, the reversal speed of the indoor fan is jointly determined according to the ambient humidity, ambient pressure at the air deflector, and the operating frequency of the air conditioner compressor, which can better achieve the anti-condensation effect of the air conditioner.

Optionally, determine the reversal speed of the indoor fan according to the humidity of the ambient humidity, the pressure of the ambient pressure, and the frequency of the operating frequency, including: when the ambient humidity is greater than or equal to the preset humidity, the ambient pressure is less than or equal to the preset humidity. Set the pressure, and when the operating frequency is greater than the first operating frequency or less than the second operating frequency, the reversing speed is determined to be the first rotational speed; when the ambient humidity is greater than or equal to the preset humidity, the ambient pressure is less than or equal to the preset pressure, and the operation When the frequency is greater than or equal to the second frequency and less than or equal to the first operating frequency, the reversing speed is determined to be the second rotational speed; when the ambient humidity is less than the preset humidity and the ambient pressure is less than or equal to the preset pressure, determine The reversing speed is the second rotational speed; when the ambient humidity is lower than the preset humidity and the ambient pressure is greater than the preset pressure, the reversing speed is determined to be the third rotational speed; wherein, the first operating frequency is greater than the second operating frequency, and the first operating frequency is greater than the second operating frequency. The rotational speed is greater than the second rotational speed, and the second rotational speed is greater than the third rotational speed.

Optionally, the value range of the preset pressure is [1020hPa, 1060hPa], for example, 1020hPa (hPa), 1040hPa, 1060hPa. When the ambient humidity is greater than or equal to the preset humidity, the ambient pressure is less than or equal to the preset pressure, and the operating frequency of the compressor is greater than the first operating frequency, the room is under high load heat exchange, and the indoor humidity and ambient temperature heat exchange are always relative When the load is high, the indoor fan will reverse at high speed; when the ambient humidity is greater than or equal to the preset humidity, the ambient pressure is less than or equal to the preset pressure, and the compressor operating frequency is less than the second operating frequency, the indoor fan will reverse at high speed and run for a short time The dew removal effect can be achieved; when the ambient humidity is greater than or equal to the preset humidity, the ambient pressure is less than or equal to the preset pressure, and the operating frequency is greater than or equal to the second frequency and less than or equal to the first operating frequency, the indoor fan maintains a medium speed Reversal can achieve better anti-condensation effect; when the ambient humidity is lower than the preset humidity, and the ambient pressure is less than or equal to the preset pressure, the indoor fan maintains a medium-speed reverse rotation, which can achieve a better anti-condensation effect; When the ambient humidity is less than the preset humidity and the ambient pressure is greater than the preset pressure, the moisture content at the air deflector is low, the ambient pressure is high, and the condensation generation conditions are poor, and the indoor fan can be reversed at a low speed to achieve better anti-condensation effect.

In some embodiments, the control method for anti-condensation of an air conditioner further includes: obtaining a current angle and a target angle of the air deflector; during the reversal process of the indoor fan, controlling the rotation of the air deflector based on the current angle and the target angle.

The target angle of the wind deflector is the angle at which the wind deflector is not easy to accumulate water droplets, for example, the plane of the wind deflector and the horizontal plane form an included angle of 60°.

Optionally, controlling the rotation of the wind deflector based on the current angle and the target angle includes: calculating the rotation angle of the wind deflector based on the current angle and the target angle; controlling the wind deflector to rotate according to the rotation angle to make the wind deflector flip to the target angle .

For example, the angle between the current air deflector plane and the horizontal plane is 20°. Based on the current angle and the target angle, the rotation angle of the air deflector is calculated to be 40°. During the reversal process of the indoor fan, control the air deflector to rotate 40° to flip to Form an angle of 60° with the horizontal plane.

In the embodiment of the present disclosure, the current angle and the target angle of the wind deflector are obtained, and the rotation of the wind deflector is controlled during the reversal process of the indoor fan, so that the wind deflector is turned to the target angle that is not easy to accumulate water droplets, and the condensation at the wind deflector is reduced. At the same time, the contact area between the air deflector and the airflow blown by the indoor fan is increased, the evaporation of condensation at the air deflector is accelerated, and the risk of water droplets caused by condensation on the air deflector can be more effectively reduced.
