Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of these features.

Example one

This embodiment provides a control method for preventing condensation of an air conditioner. As shown in FIG. 1, in the cooling mode, the following steps are performed:

S1, real-time detection and acquisition of indoor ambient temperature Ta, preferably, real-time detection of indoor ambient temperature Ta through the temperature sensor already possessed by the air conditioner, and transmission of the detected indoor ambient temperature Ta to the controller;

S2. The controller calculates the difference between the indoor ambient temperature Ta and the set temperature Ts according to the received indoor ambient temperature Ta, and judges based on the difference to determine whether anti-condensation control is required, and the set temperature Ts is passed by the user The temperature set by the remote control, or the temperature set by the air conditioner according to a specific method, is usually the target temperature that the user pre-enables the indoor environment through the air conditioner or the air conditioner itself;

S3. According to the judgment result of step S2, when anti-condensation control is required, the air conditioner is controlled to perform anti-condensation control. The anti-condensation control includes constant or increased compressor frequency, and the judgment result is that anti-condensation is required. During the dew control, the frequency of the air-conditioning compressor is not reduced, so that the cooling capacity of the compressor will not be reduced by entering the anti-condensation control. In this step, the anti-condensation control can be used to increase the air volume, such as increasing the air guide door The opening degree of the internal fan is increased, etc.

The control method for preventing condensation in the air conditioner described in this embodiment is detected by the existing devices in the air conditioner, and other devices are not needed for control, and it is easy to implement. When the method is judged according to the results of this embodiment to prevent During condensation control, the compressor frequency is not reduced, and the cooling capacity of the air conditioner is not reduced, which ensures the user's demand for cooling capacity.

In the embodiment of the present disclosure, the anti-condensation control only refers to the control process that does not reduce the compressor frequency in the embodiment of the present disclosure.

Example two

On the basis of the first embodiment, this embodiment provides a specific judgment method of step S2. When the difference between the air-conditioning room temperature and the set temperature is large, the indoor environment temperature is in a relatively high state, and the cold air blowing out is different from the indoor temperature. The temperature difference is large, and the air conditioner is prone to condensation. However, when the indoor environment temperature decreases, if the frequency remains the same, the coil temperature and the outlet temperature will decrease accordingly. At this time, the alternating hot and cold near the outlet will be more serious. Condensation is prone to occur. When the indoor temperature decreases and the indoor temperature is not much different from the set temperature, the cold air blowing out is still less than the indoor ambient temperature because the compressor is still working, and the air deflector is blowing cold air relative to the temperature inside the air conditioner The effect is low, and the temperature on the outside of the air conditioner is relatively high under the effect of the indoor environment temperature, and condensation is also prone to occur. At this time, the indoor environment temperature is not much different from the set temperature. Condensation is ignored. On the basis of Embodiment 1, this embodiment provides a specific control method in conjunction with FIG. 2, which specifically includes:

S21. First judgment: the air conditioner detects and acquires the indoor ambient temperature Ta in real time, acquires the set temperature Ts, and performs the first judgment at the time when the cooling mode is turned on or the fourth time period t4 after the cooling mode is turned on, and calculates the indoor ambient temperature Ta Determine whether the difference ΔT1 is less than or equal to the first preset value A. If the difference ΔT1 is less than or equal to the first preset value A, then the The second judgment is to determine whether it is necessary to enter the anti-condensation control according to the result of the second judgment. If the difference ΔT1 is greater than the first preset value A, the anti-condensation control will not be performed, and the air conditioner will operate as preset In this embodiment, the difference ΔT1 at the beginning of the cooling mode is generally large, and in most cases it is greater than the first preset value A. With the operation of the air conditioning cooling mode, the difference ΔT1 will gradually decrease and reduce to It is less than or equal to the first preset value A. After the cooling mode is turned on, it runs for a fourth time period t4 and then performs the first judgment, so that the air conditioner will detect whether condensation is prone to occur during a period of cooling, which shortens the judgment process. The fourth time period t4 is Within the range of 0-30min, preferably 5min;

In this step, preferably, when the difference ΔT1 is greater than the first preset value A, the anti-condensation control is not performed, the air conditioner operates according to the preset setting, and returns to perform the first judgment again to ensure that the The judgment process of this embodiment is performed throughout the cooling mode, and the judgment is more accurate and complete. It is better to wait for the first time period t1 and then return to perform the first judgment again. The first time period t1 can be determined according to the difference ΔT1. If the difference ΔT1 is large, the first time length t1 can be longer. When the difference ΔT1 is small but still greater than the first preset value A, the first time length t1 is relatively short, making the judgment process simpler and more reasonable. Similarly, the first time length t1 can be zero, that is, the judgment is completed and the first judgment is returned immediately. In this embodiment, the first preset value A is in the range of 3-5°C.

S22. Second judgment: when the difference ΔT1 is less than or equal to the first preset value A, enter the second judgment. When entering the second judgment, with the progress of time, according to multiple sets of indoor environments detected in real time Temperature Ta, calculate the real-time difference △T2 between multiple sets of indoor ambient temperature Ta and the set temperature Ts. As time goes on, the real-time difference △T2 is the collection of the difference between the indoor ambient temperature Ta and the set temperature Ts. While recording the real-time difference △T2, record the continuous duration tc when the real-time difference △T2 is less than or equal to the first preset value A. When the real-time difference △T2 occurs at any moment in time, the difference is greater than the first At a preset value A, the recording time stops, the time between the stop time and the start recording time is the continuous duration tc, and the continuous duration tc is the real-time difference △T2 is always less than or equal to the first preset value A When the real-time difference △T2 is greater than the first preset value A for a time point or a period of time, return to the first judgment. When the continuous duration tc is recorded, it is determined whether the continuous duration tc is greater than or equal to The second preset value B, if the continuous duration tc is greater than or equal to the second preset value B, the anti-condensation control is performed, and the continuous duration tc is less than the second preset value B, and the anti-condensation control is not performed. Operate as preset. In this step, preferably, when the continuous duration tc is less than the second preset value B, no anti-condensation control is performed, and the air conditioner operates according to the preset settings, and returns to continue recording. Time length tc and make the second judgment. It is better to wait for the second time length t2 before making the second judgment. The second time length t2 can be determined according to the continuous duration tc. The larger the continuous duration tc, the second time length t2. The smaller, in this step, the blowing time is used as the judgment when the indoor ambient temperature Ta is close to the set temperature Ts to prevent the condensation phenomenon caused by long-term blowing of cold air. Preferably, the second preset value B is 60 Within the range of ~90min, that is, when the cold air is blown for more than 60~90min, it is judged to be easy to produce condensation.

In this embodiment, when entering the anti-condensation control, step S3 is entered. As shown in FIG. 3, step S3 includes the following steps:

S31. Control the air guide door to run to the position of the maximum air outlet area. Under normal circumstances, in conjunction with Figure 4, when it is opened to position 5 in Figure 4, the up and down direction in Figure 4 is the up and down direction during actual operation of the air conditioner. The air guide door is fully opened, the air outlet area of the air conditioner is the largest, or the air guide door is opened to be parallel to the direction of the air blowing to the inner side of the air guide door. At this time, the air guide door has the least blocking effect on the air. The temperature difference between the inner side and the outer side is reduced, and the air guide door is adjusted to a position that is not easy to produce condensation, which prevents the occurrence of condensation. When there are multiple air guide doors on the air conditioner, the multiple air guide doors follow this step The method controls the angle of all air guide doors.

S32. The rotation speed of the inner fan is increased by △N on the basis of the existing rotation speed to increase the air output of the fan. In this embodiment, the angle of the air guide door and the rotation speed of the inner fan are adjusted to increase the air output, but the cooling capacity of the air conditioner is not reduced, ensuring the user For the demand for cooling capacity, in this step, the △N is in the range of 50-100r/min. It is better to determine the value of △N according to the air outlet position of the fan in the air conditioner, and the air outlet position corresponds to The higher the speed of the internal fan, the greater the value of △N. For example, when the air conditioner is divided into multiple gears of strong/high wind, medium wind and low wind/silent, when the existing speed is strong/high wind, The △N is in the range of 80-100r/min. When the current speed is in the medium-wind gear, the △N is in the range of 60-80r/min. When the current speed is in the low-wind/silent gear, the △N is In the range of 50-60r/min, when the speed is increased, the speed can be increased at a time, and it is better to increase the speed by increasing the interval, for example, at the first increase, increase by 30r/min, Increase by 20r/min after a period of time, and increase in this way.

In this embodiment, when step S3 is entered, that is, after entering the anti-condensation control, the third judgment is entered to determine when to launch the anti-condensation control. The third judgment includes:

Calculate the difference ΔT1 at the moment of entering the third judgment, and judge whether the difference ΔT1 is greater than the first preset value A, or whether the compressor is stopped, if yes, exit the anti-condensation control, otherwise continue to run In the anti-condensation control, when the judgment result of the third judgment is no, continue to run the anti-condensation control, and wait for the third time period t3 and then return to the third judgment until the difference ΔT1 is greater than the The first preset value A or the compressor is stopped, and the value of the third time period t3 is determined according to the specific operating conditions of the air conditioner.
