[0035] With the development of intelligent technology and the improvement of consumer demands, air conditioners are endowed with other functions in addition to refrigeration and heating, such as self-cleaning and sterilization functions. During the self-cleaning and sterilization process, the temperature of the indoor coil is usually required to reach above 56°C. When the temperature of the indoor coil is used as the object of adjustment, there may be a problem of temperature fluctuation, resulting in a situation where some bacteria cannot be killed.

[0036] Combined with Figure 1 As shown, the embodiments of the present disclosure provide a method for cleaning control of an air conditioner, including:

[0037] S210, the air conditioner obtains the target frequency of the compressor in response to a cleaning instruction.

[0038] S220, the air conditioner adjusts the target exhaust temperature of the compressor according to the target frequency, so that the target exhaust temperature is greater than the first set temperature.

[0039] Using the method for air conditioner cleaning control provided by the embodiments of the present disclosure, when high-temperature sterilization is required, the air conditioner receives and responds to a cleaning instruction. The target frequency of the compressor is obtained, and it is determined whether the target frequency of the compressor is suitable for high-temperature sterilization, so as to avoid compressor failures affecting the service life of the air conditioner. According to the target frequency of the compressor, the target exhaust temperature of the compressor is adjusted to make the target exhaust temperature higher than a first set temperature. Since the exhaust temperature of the compressor is the highest temperature point in the air conditioner and has a small difference from the temperature of the inner coil, when the target exhaust temperature is higher than the first set temperature, it can ensure that the temperature of the inner coil always meets the requirements of high temperature, so as to improve the effect of high-temperature sterilization of the air conditioner.

[0040] Optionally, the value range of the first set temperature is [56, 56.4] °C. Preferably, the first set temperature is 56.1 °C, 56.2 °C or 56.3 °C. In this way, since the target exhaust temperature of the compressor is controlled to be higher than the value of the above first set temperature, and the temperature of the inner coil has a small difference from the target exhaust temperature, the temperature of the inner coil can still be maintained above the temperature required for sterilization under the condition of large changes in indoor and outdoor environmental parameters.

[0041] Combined with Figure 2 As shown, the embodiments of the present disclosure provide another method for air conditioner cleaning control, including:

[0042] S210, the air conditioner responds to the cleaning instruction and obtains the target frequency of the compressor.

[0043] S230, when the target frequency is higher than a first set frequency, the air conditioner keeps the target frequency unchanged and executes step S250.

[0044] S240, when the target frequency is less than or equal to the first set frequency, the air conditioner adjusts the target frequency.

[0045] S250, the air conditioner determines the target exhaust temperature of the compressor according to the target frequency.

[0046] S260, the air conditioner adjusts the target exhaust temperature according to the relationship between the target exhaust temperature and the first set temperature.

[0047] Using the method for air conditioner cleaning control provided by the embodiments of the present disclosure, since the exhaust temperature of the compressor required for high-temperature sterilization is high, operating at a low target frequency is likely to cause failures such as compressor running out of step, thereby affecting the service life and reliability of the air conditioner. By adjusting the target frequency of the compressor, the target frequency is adapted to the required exhaust temperature, improving the operating stability of the compressor while meeting the requirements of the exhaust temperature.

[0048] Optionally, the value range of the first set frequency is [40, 44] Hz. Preferably, the first set frequency is 41 Hz, 42 Hz or 43 Hz. In this way, since the target exhaust temperature of the compressor is controlled to be greater than the first set temperature, when the value of the target frequency is greater than the value of the above first set frequency, the target frequency of the compressor is adapted to the required exhaust temperature. Since the compressor operates at medium-high frequency at high exhaust temperature, the operating reliability and stability can be improved.

[0049] Combined with Figure 3 As shown, the embodiments of the present disclosure provide another method for air conditioner cleaning control, including:

[0050] S210, the air conditioner obtains the target frequency of the compressor in response to the cleaning instruction.

[0051] S230, when the target frequency is greater than the first set frequency, the air conditioner keeps the target frequency unchanged and executes step S250.

[0052] S241, when the target frequency is less than or equal to the first set frequency, the air conditioner increases the target frequency by the compensation frequency.

[0053] S242, when the target frequency is greater than the first set frequency, the air conditioner keeps the target frequency unchanged and executes step S250.

[0054] S243, when the target frequency is less than or equal to the first set frequency, the air conditioner determines the second set frequency as the target frequency.

[0055] S250, the air conditioner determines the target exhaust temperature of the compressor according to the target frequency.

[0056] S260, the air conditioner adjusts the target exhaust temperature according to the relationship between the target exhaust temperature and the first set temperature.

[0057] Wherein, the second set frequency is greater than the first set frequency.

[0058] Adopting the method for air conditioner cleaning control provided by the embodiments of the present disclosure, when the target frequency cannot make the compressor operate stably during the high-temperature sterilization process, the target frequency is increased by the way of self-increasing the compensation frequency. Since the compressor operates at a low target frequency only when the indoor environment temperature and the outdoor environment temperature are relatively high, when the target frequency still cannot meet the requirement of the compressor for stable operation after being increased, the target frequency is adjusted to the second set frequency higher than the first set frequency. Since the adjusted target frequency is higher than the first set frequency, the frequency margin is increased to avoid the target frequency from making the compressor unable to operate stably under the current indoor and outdoor environment temperatures, and the operating stability of the compressor at high exhaust temperature is improved.

[0059] Optionally, the compensation frequency ranges from 8 Hz to 12 Hz. Preferably, the compensation frequency is 9 Hz, 10 Hz or 11 Hz. The second set frequency ranges from 45 Hz to 49 Hz. Preferably, the second set frequency is 46 Hz, 47 Hz or 48 Hz. In this way, when the compensation frequency is within the above range, the change in the target frequency of the compressor is small, avoiding large fluctuations in operating parameters and thus improving the operating stability of the compressor. When the second set frequency is within the above range, the margin difference from the first set frequency enables the compressor to operate stably at the current indoor and outdoor environmental temperatures, improving the operating stability of the compressor at high exhaust temperatures.

[0060] Combined with Figure 4 As shown, the embodiments of the present disclosure provide another method for air conditioner cleaning control, including:

[0061] S210. The air conditioner obtains the target frequency of the compressor in response to a cleaning instruction.

[0062] S230. When the target frequency is greater than the first set frequency, the air conditioner keeps the target frequency unchanged and executes step S251.

[0063] S240. When the target frequency is less than or equal to the first set frequency, the air conditioner adjusts the target frequency.

[0064] S251. The air conditioner detects the outdoor environmental temperature.

[0065] S252. The air conditioner determines the target exhaust temperature of the compressor according to the target frequency and the outdoor environmental temperature.

[0066] S261. When the target exhaust temperature is greater than the first set temperature, the air conditioner keeps the target exhaust temperature unchanged and this control ends.

[0067] S262. When the target exhaust temperature is less than or equal to the first set temperature, the air conditioner determines the second set temperature as the target exhaust temperature and this control ends.

[0068] Wherein, the second set temperature is greater than the first set temperature.

[0069] By using the method for air conditioner cleaning control provided in the embodiments of the present disclosure, since the target frequency of the compressor affects the target exhaust temperature, the target exhaust temperature is re-determined after the target frequency is determined. By detecting the outdoor ambient temperature and determining the target exhaust temperature according to the outdoor ambient temperature, temperature compensation is performed on the target exhaust temperature determined by the target frequency. When the determined target exhaust temperature is greater than the first set temperature, the target exhaust temperature can enable the inner coil temperature to achieve high-temperature sterilization and keep the target exhaust temperature unchanged. When the determined target exhaust temperature is less than or equal to the first set temperature, the target exhaust temperature is adjusted to the second set temperature with a margin to avoid the situation that the target exhaust temperature cannot make the inner coil temperature reach the sterilization temperature. By determining the target exhaust temperature according to the target frequency and the outdoor ambient temperature and making adjustments when the target exhaust temperature is low, the inner coil temperature always meets the high-temperature requirement to improve the high-temperature sterilization effect of the air conditioner.

[0070] Optionally, when the outdoor ambient temperature is constant, the higher the target frequency, the higher the target exhaust temperature. When the target frequency is constant, the higher the outdoor ambient temperature, the higher the target exhaust temperature. The air conditioner in step S252 determines the target exhaust temperature of the compressor according to the target frequency and the outdoor ambient temperature, including: T d = α × f t + β + γ. Wherein, T d is the target exhaust temperature, α is the frequency conversion coefficient, f t is the target frequency, β is the temperature correction amount, and γ is the outdoor ambient temperature compensation amount. The value range of the frequency conversion coefficient α is [0.01, 2]. According to the differences in the models of the air conditioner and the compressor, application scenarios, and environmental parameters, etc., α takes different values. For the method for air conditioner cleaning control provided in the embodiments of the present disclosure, the value range of α is [0.5, 0.7]. The value range of the temperature correction amount β is [-50, 200]. According to the differences in the models of the air conditioner and the compressor, application scenarios, and environmental parameters, etc., β takes different values. For the method for air conditioner cleaning control provided in the embodiments of the present disclosure, the value range of β is [20, 80]. The correspondence between the outdoor ambient temperature compensation amount and the outdoor ambient temperature is shown in Table 1. In this way, the target exhaust temperature can be accurately calculated according to the target frequency and the outdoor ambient temperature, and the target exhaust temperature is adapted to the target frequency and the outdoor ambient temperature, improving the operating stability of the compressor. Due to the high accuracy of the target exhaust temperature, the inner coil temperature is always maintained above the temperature required for sterilization to improve the high-temperature sterilization effect of the air conditioner.

[0071] The correspondence between the outdoor ambient temperature compensation amount and the outdoor ambient temperature is shown in Table 1:

[0072] Table 1

[0073] <![CDATA[T ao > <![CDATA[T ao ≤ 0 °C]]> <![CDATA[0 °C < T ao ≤ 10 °C]]> <![CDATA[10℃ < T ao ≤ 20℃]]> <![CDATA[20℃ < T ao > γ -13 -3 6 8

[0074] Among them, T ao is the outdoor ambient temperature, and γ is the outdoor ambient temperature compensation amount.

[0075] Optionally, the value range of the second set temperature is [58, 58.4] °C. Preferably, the second set temperature is 58.1 °C, 58.2 °C or 58.3 °C. In this way, when the value of the second set temperature is within the above range, the margin difference from the first set temperature enables the inner coil temperature to reach the sterilization temperature, so as to improve the high-temperature sterilization effect of the air conditioner.

[0076] Combined with Figure 5 as shown, the embodiment of the present disclosure provides another method for air conditioner cleaning control, including:

[0077] S210, the air conditioner responds to the cleaning instruction and obtains the target frequency of the compressor.

[0078] S220, the air conditioner adjusts the target exhaust temperature of the compressor according to the target frequency, so that the target exhaust temperature is greater than the first set temperature.

[0079] S270, the air conditioner controls the compressor to operate at the target frequency.

[0080] S280, the air conditioner adjusts the rotation speed of the outdoor fan.

[0081] S290, the air conditioner detects the current exhaust temperature of the compressor.

[0082] S300, when the current exhaust temperature is less than the target exhaust temperature, the air conditioner adjusts the opening degree of the electronic expansion valve and returns to step S290.

[0083] Adopting the method for air conditioner cleaning control provided by the embodiment of the present disclosure, before high-temperature sterilization, the operating frequency of the compressor and the rotation speed of the outdoor fan are adjusted. After the frequency and rotation speed are adjusted, the current exhaust temperature of the compressor is detected. When the current exhaust is less than the target exhaust temperature, the inner coil temperature does not reach the sterilization temperature, resulting in a poor sterilization effect. By adjusting the opening degree of the electronic expansion valve, the current exhaust temperature of the compressor is adjusted to the target exhaust temperature, so that the inner coil temperature meets the high-temperature requirements to improve the high-temperature sterilization effect of the air conditioner.

[0084] Optionally, the air conditioner in step S280 adjusts the rotational speed of the outdoor fan, including: the air conditioner determines the target rotational speed of the outdoor fan corresponding to the outdoor ambient temperature and the target frequency according to the outdoor ambient temperature and the target frequency. The air conditioner adjusts the rotational speed of the outdoor fan to the target rotational speed. In this way, when the outdoor ambient temperature is low, by increasing the rotational speed of the outdoor fan, the current exhaust temperature of the compressor reaches the target exhaust temperature. When the target frequency is high, by increasing the rotational speed of the outdoor fan, the current exhaust temperature of the compressor reaches the target exhaust temperature. By determining the corresponding target rotational speed of the outdoor fan at different outdoor ambient temperatures and target frequencies, the current exhaust temperature of the compressor reaches the target exhaust temperature to improve the high-temperature sterilization effect of the air conditioner.

[0085] The corresponding relationship between the target rotational speed of the outdoor fan and the outdoor ambient temperature and the target frequency is shown in Table 2:

[0086] Table 2

[0087]

[0088] Wherein, T ao is the outdoor ambient temperature, f t is the target frequency of the compressor, and n t is the target rotational speed of the outdoor fan.

[0089] Optionally, the air conditioner in step S300 adjusts the opening degree of the electronic expansion valve, that is, the air conditioner determines the opening degree correction amount of the electronic expansion valve through proportional-integral-derivative control according to the current exhaust temperature. The air conditioner determines the sum of the current opening degree of the electronic expansion valve and the opening degree correction amount as the target opening degree. The air conditioner adjusts the opening degree of the electronic expansion valve to the target opening degree. In this way, according to the current exhaust temperature, the opening degree correction amount of the electronic expansion valve is determined through proportional-integral-derivative control, and the opening degree of the electronic expansion valve is gradually adjusted. The opening degree correction amount is based on the current exhaust temperature. After each opening degree adjustment, the current exhaust temperature can be closer to and even reach the target exhaust temperature. Through proportional-integral-derivative control, the accuracy of the adjustment of the current exhaust temperature is improved to improve the high-temperature sterilization effect of the air conditioner.

[0090] Combined with Figure 6 shown, the embodiment of the present disclosure provides another method for air conditioner cleaning control, including:

[0091] S210, the air conditioner responds to the cleaning instruction and obtains the target frequency of the compressor.

[0092] S220, the air conditioner adjusts the target exhaust temperature of the compressor according to the target frequency, so that the target exhaust temperature is greater than the first set temperature.

[0093] S270, the air conditioner controls the compressor to operate at the target frequency.

[0094] S280, the air conditioner adjusts the rotational speed of the outdoor fan.

[0095] S290, the air conditioner detects the current exhaust temperature of the compressor.

[0096] S300, when the current exhaust temperature is less than the target exhaust temperature, the air conditioner adjusts the opening degree of the electronic expansion valve and returns to step S290.

[0097] S310, when the current exhaust temperature is greater than or equal to the target exhaust temperature, the air conditioner controls the indoor fan to stop running.

[0098] S320, when the control of the indoor fan stopping running reaches the first set time, the air conditioner controls the indoor fan to run at the set rotational speed.

[0099] S330, the air conditioner adjusts the angle of the air deflector to the set angle.

[0100] S340, when the control of the indoor fan running at the set rotational speed reaches the second set time, the air conditioner operates in the state before responding to the cleaning instruction.

[0101] By using the method for air conditioner cleaning control provided in the embodiments of the present disclosure, when the current exhaust temperature is greater than or equal to the target exhaust temperature, the temperature of the inner coil has reached the sterilization temperature, and high-temperature sterilization can be performed. At the beginning stage of high-temperature sterilization, the indoor fan is controlled to stop running so that the indoor heat exchanger can be fully preheated and sterilized. After the preheating is completed, the indoor fan is controlled to run at the set rotational speed to circulate and sterilize the air in the room. By adjusting the angle of the air deflector to the set angle, it is avoided that the hot air circulated indoors blows towards the user and causes physical discomfort. After the cleaning is completed, the operating state before the sterilization operation is restored to make the air conditioner operate normally.

[0102] Optionally, the value range of the first set time is [4, 6] min. Preferably, the first set time is 4.5 min, 5 min or 5.5 min. The value range of the second set time is [24, 26] min. Preferably, the second set time is 24.5 min, 25 min or 25.5 min. The value range of the set rotational speed is [600, 700] rpm. Preferably, the set rotational speed is 625 rpm, 650 rpm or 675 rpm. The value range of the set angle is [15, 25]°. Preferably, the set angle is 18°, 20° or 22°. Wherein, the set angle is the angle relative to the horizontal plane. In this way, when the value of the first set time is within the above range, the indoor heat exchanger can be fully preheated, avoiding waste of electric energy caused by insufficient preheating or over-preheating. When the value of the second set time is within the above range, the time of high-temperature sterilization can kill the bacteria in the indoor heat exchanger and the indoor air, avoiding the residual bacteria caused by short sterilization time or the waste of electric energy and discomfort of users caused by long sterilization time. When the value of the set rotational speed is within the above range, the bacteria in the air can be evenly killed, avoiding the extension of the sterilization time caused by slow speed or the residual bacteria caused by fast speed. When the value of the set angle is within the above range, the direction of the air deflector facing upwards can avoid the users, avoiding the discomfort caused by the hot air to the user's body.

Optionally, the device may further include a communication interface 43 and a bus 44.
