The invention relates to the technical field of air conditioners, in particular to an outdoor unit dust removal control method and device, an air conditioner and a storage medium.
Background
The outdoor unit of the air conditioner is placed outdoors, dust is easily collected by the heat exchanger, and the dust on the heat exchanger can influence the air output of the indoor unit of the air conditioner, so that the refrigerating and heating effects of the air conditioner are influenced. At present, aiming at the dirty blockage of an air conditioner outdoor unit caused by dust accumulation and the like, the mode generally adopted is manual dust removal, for high-rise users, the outdoor unit is placed at the outdoor high altitude, and the operation is complex, the consumed time is long, and the safety risk exists when professional technicians clean the high altitude operation. In addition, most of the existing air conditioners only need to clean the heat exchanger regularly on the specification, but do not have the function of automatically reminding the dirty and blocked heat exchanger, namely, the dust removal time cannot be judged, inconvenience is brought to dust removal, and users even directly neglect to clean the heat exchanger.
Disclosure of Invention
The invention solves the problem that the dust removal time is difficult to judge when the outdoor unit of the air conditioner removes dust.
In order to solve the above problems, the present invention provides a dust removal control method for an outdoor unit, wherein the outdoor unit includes a fan and a condenser, and includes:
acquiring fan current and condenser exhaust pressure;
and judging whether to remove dust of the outdoor unit or not according to the fan current and the condenser exhaust pressure.
The invention judges whether the outdoor unit needs dust removal or not under the comprehensive control of the fan current and the condenser exhaust pressure, can realize the accurate judgment of dust removal, and avoids the error judgment caused by the fault of the fan when judging whether the outdoor unit needs dust removal or not only according to the fan current.
Further, the determining whether to remove dust from the outdoor unit according to the fan current and the condenser exhaust pressure includes:
when the current of the fan is larger than a preset current value, the outdoor unit does not need to remove dust;
and when the current of the fan is smaller than or equal to the preset current value, judging whether to remove dust on the outdoor unit or not according to the exhaust pressure of the condenser.
Therefore, under the constraint of two control conditions of the fan current and the condenser sheet exhaust pressure, the detection accuracy can be ensured, and when dust removal is not needed, dust removal judgment can be directly quit, and normal operation of the outdoor unit is not influenced.
Further, the determining whether to remove dust from the outdoor unit according to the condenser discharge pressure includes:
when the condenser exhaust pressure is smaller than a first preset pressure value, the outdoor unit does not need to remove dust;
and when the condenser exhaust pressure is greater than or equal to the first preset pressure value, dedusting the outdoor unit.
Therefore, when the current of the fan is smaller than or equal to the preset current value but the exhaust pressure of the condenser is smaller than the first preset pressure value, the outdoor unit is judged not to need to be dedusted. The lower fan current may be due to a fan failure. When the current of the fan is smaller than or equal to the preset current value and the exhaust pressure of the condenser is larger than or equal to the first preset pressure value, the dust accumulation degree on the outdoor unit is serious, and the outdoor unit needs to be subjected to dust removal treatment, so that the detection accuracy is ensured.
Further, before performing dust removal on the outdoor unit, the method further includes:
and acquiring a dust removal grade for removing dust of the outdoor unit according to the pressure of the condenser exhaust gas, and executing a dust removal mode on the outdoor unit according to the dust removal grade.

Further, the obtaining of the dust removal level for removing dust from the outdoor unit according to the discharge pressure of the condenser includes:
when the condenser exhaust pressure is greater than or equal to a first preset pressure value and less than a second preset pressure value, the dust removal grade is a first grade;
and when the condenser exhaust pressure is greater than or equal to a second preset pressure value, the dedusting grade is a second grade.
From this, can be suitable for different dust removal intensity according to user's different demands, guarantee dust removal effect on the one hand, still avoid simultaneously reducing air conditioner travelling comfort because of the too big or time overlength of dust removal intensity brings to and avoid the energy extravagant.
Further, the dust removal mode comprises reverse dust removal by the fan and forward and reverse dust removal by the fan; the executing a dust removal mode on the outdoor unit according to the dust removal grade includes:
when the dust removal grade is a first grade, the dust removal mode is that the fan is used for reversely removing dust;

Therefore, for the serious dust accumulation, the forward and reverse rotation of the fan is adopted for dust removal, and the dust removal efficiency and the cleaning degree can be improved compared with the reverse rotation of the forward and reverse rotation dust removal under the same rotating speed of the fan.
Further, according to the magnitude of the condenser exhaust pressure, the first grade and the second grade respectively comprise a plurality of gears, and in the range of the first grade or the second grade, the larger the condenser exhaust pressure is, the higher the gears are, and the larger the rotation speed of the fan is when the fan is used for reverse rotation dust removal or forward and reverse rotation dust removal.
The invention finely divides the dust removal grade, so that the dust removal mode is matched with the dust deposition degree, and dust removal is carried out more pertinently.

When the laying dust is serious, the fan is in a positive and negative rotation mode, so that the phenomenon that the noise of the outdoor unit is increased due to the increase of the rotating speed, the comfort of a user is influenced, and the service life of the fan is prolonged can be avoided.
Further, the first gear comprises a first gear, a second gear and a third gear;
when the condenser exhaust pressure is greater than or equal to a first preset pressure value and less than a third preset pressure value, the dust removal grade is a first gear;

and when the condenser exhaust pressure is greater than or equal to a fourth preset pressure value and less than a second preset pressure value, the dust removal grade is a third gear.
Divide into three gears with first grade, can correspond with the high, medium and low three wind shelves of fan from this, the fan rotational speed of being convenient for is adjusted.
Further, when the dust removal grade is a first gear, the dust removal mode is that the fan reversely removes dust at a low wind gear rotating speed;
when the dust removal grade is a second gear, the dust removal mode is that the fan reversely removes dust at a medium gear rotating speed;
and when the dust removal grade is a third gear, the dust removal mode is that the fan reversely removes dust at a high wind gear rotating speed.
This embodiment can improve dust collection efficiency and clean degree through improving the fan rotational speed, and the regulative mode is simple, directly adjust the fan windscreen can.
Further, the second gear comprises a fourth gear and a fifth gear;
when the condenser exhaust pressure is greater than or equal to a second preset pressure value and less than a fifth preset pressure value, the dust removal grade is a fourth gear;
and when the condenser exhaust pressure is greater than or equal to a fifth preset pressure value, the dust removal grade is a fifth gear.
Therefore, the dust removal in the second-level range is finely divided, so that the dust removal intensity is matched with the dust deposition degree.
