Based on the above air conditioner, the embodiment of the invention provides a method for removing dust from a condenser, wherein an execution main body is a controller, as shown in fig. 2, and the method comprises the following steps:
step S202, when an air conditioner is started to operate and an outdoor fan reaches the maximum rotating speed, acquiring a first acquisition voltage corresponding to a wind speed acquisition device;
the first acquisition voltage is used for representing a voltage value generated by rotation of the wind speed acquisition device under the wind speed action of the outdoor fan; specifically, after the air conditioner is started and operated every time, when the outdoor fan reaches the maximum rotating speed, the first acquisition voltage corresponding to the wind speed collector at the moment is acquired, and whether the condenser is dedusted is judged according to the first acquisition voltage.
It should be noted that, if the rotational speed setting of the outdoor fan is divided into a low rotational speed, a medium rotational speed and a high rotational speed, the maximum rotational speed is the high rotational speed; if the rotational speeds of the outdoor fans are set to rotational speeds of different proportions, the maximum rotational speed is the rotational speed of the maximum proportion, and therefore, the maximum rotational speed is determined according to the actual rotational speed setting of the outdoor fans.
Step S204, judging whether the first acquisition voltage is smaller than a preset first voltage threshold value;
specifically, judging whether the condenser removes dust or not according to a first collection voltage corresponding to the wind speed collector and a preset first voltage threshold value; the preset first voltage threshold may be determined according to a reference acquisition voltage.
Further, the method comprises the following steps: when the air conditioner is started for use for the first time and the outdoor fan reaches the maximum rotating speed, acquiring a reference acquisition voltage corresponding to the wind speed acquisition device; determining a preset first voltage threshold according to the reference acquisition voltage; specifically, when the air conditioner is first started and used after being installed, at this time, the condenser has no dust accumulation, and when the outdoor fan reaches the maximum rotation speed at this time, the voltage value corresponding to the wind speed collector can be used as a reference collection voltage, and the preset first voltage threshold value, for example, the reference collection voltage V0 is determined to be 3V, at this time, the preset first voltage threshold value v1= 0.3V0, that is, the preset first voltage threshold value is 0.9V.
Step S206, if yes, controlling the air conditioner to enter a dust removal mode;
specifically, when the first collected voltage is smaller than a preset first voltage threshold, the fact that the dust accumulation of the condenser is more is indicated, and the condenser needs to be dedusted, namely the air conditioner is controlled to enter a dedusting mode; when the first acquisition voltage is not smaller than a preset first voltage threshold value, the condenser is not required to remove dust; at this time, the air conditioner is controlled to continue normal operation, such as operation according to a preset heating mode or cooling mode, etc.
Step S208, in the dust removal mode, triggering the resonator to start so that the resonator drives the fins of the condenser to vibrate according to a first preset time length; meanwhile, the outdoor fan is controlled to reversely run according to the second preset time length so as to remove dust from the condenser.
In the dust removing mode, the controller triggers the resonator to start so that the resonator drives the fins of the condenser to vibrate according to a first preset time period, and the fins of the condenser and the resonator reach resonance points to resonate, at the moment, the fins of the condenser vibrate the dust greatly, and therefore the intractable dust on the condenser vibrates and loosens; meanwhile, the outdoor fan is controlled to reversely run according to the second preset time length, and the vibration loosening dust removal is reversely blown out, so that the automatic dust removal of the condenser is realized, and the dust removal efficiency and the dust removal effect are ensured.
It should be noted that, the second preset duration is not less than the first preset duration, if the first preset duration is 15s, the second preset duration is 35s, so that when the outdoor fan reversely rotates, the intractable dust loosened by vibration can be completely reversely blown out, and the dust removing effect of the condenser is improved.
According to the condenser dust removing method, when the air conditioner is started and operated and the outdoor fan reaches the maximum rotating speed, the first collecting voltage corresponding to the wind speed collector is obtained; when the first acquisition voltage is smaller than a preset first voltage threshold value, triggering the resonator to start so that the resonator drives the fins of the condenser to vibrate according to a first preset time length; meanwhile, the outdoor fan is controlled to reversely run according to the second preset time length so as to remove dust from the condenser, in the dust removing mode, the resonator drives the fins of the condenser to resonate so as to automatically remove dust from the condenser, so that dust accumulation of the condenser is reduced, the heat exchange effect of the condenser is ensured, the air conditioner can play an optimal role, and the comfort level of a user is improved; and the method has the characteristics of lower dust removal implementation cost, low energy consumption and simple and effective dust removal control mode, and is convenient to popularize and implement in practical application.
Further, the method comprises the following steps: when the time length of the reverse rotation operation of the outdoor fan reaches a second preset time length, controlling the forward rotation operation of the outdoor fan; when the outdoor fan reaches the maximum rotating speed, acquiring a second acquisition voltage corresponding to the wind speed acquisition device; judging whether the second acquisition voltage is not smaller than a preset second voltage threshold value or not; the preset second voltage threshold is larger than the preset first voltage threshold; and if so, controlling the air conditioner to exit the dust removal mode. Specifically, in the dust removal mode, when the time length of the reverse running of the outdoor fan reaches a second preset time length, stopping dust removal, controlling the forward running of the outdoor fan, judging whether the air conditioner is controlled to exit the dust removal mode, namely, when the outdoor fan reaches the maximum rotating speed, acquiring a second acquisition voltage corresponding to the wind speed acquisition device; judging whether the second acquisition voltage is not smaller than a preset second voltage threshold value or not; if so, controlling the air conditioner to exit the dust removing mode, otherwise, if the second collecting voltage is smaller than a preset second voltage threshold value, repeatedly removing dust from the condenser according to the dust removing mode, namely, triggering the starting of the resonator again, so that the resonator drives the fins of the condenser to vibrate according to a first preset duration; meanwhile, the outdoor fan is controlled to reversely run according to the second preset time length so as to remove dust from the condenser again.
The electric appliance can age, so that the preset second voltage threshold value for exiting the dust removing mode is larger than the preset first voltage threshold value; here, a preset second voltage threshold value is determined according to the reference acquisition voltage, such as a preset second voltage threshold value v2= 0.8V0; it should be noted that, the preset first voltage threshold and the preset second voltage threshold are determined according to the reference acquisition voltage, and only the preset second voltage threshold is required to be satisfied and is greater than the preset first voltage threshold.
Further, the air conditioner further comprises an alarm module, and in the process of repeatedly dedusting the condenser according to the dedusting mode, the method further comprises the following steps: when the dust removal times reach the preset times, acquiring a third acquisition voltage corresponding to the wind speed collector; judging whether the third acquisition voltage is smaller than a preset second voltage threshold value or not, and is not smaller than a preset first voltage threshold value; if yes, generating first alarm information; and sending the first alarm information to the alarm module so that the alarm module carries out alarm prompt according to the first alarm information to prompt a user to carry out manual dust removal on the condenser. Specifically, when the dust removal times reach the preset times, at this time, the third collection voltage is still smaller than the preset second voltage threshold and larger than the preset first voltage threshold, the controller generates first alarm information and sends the first alarm information to the alarm module, so that the alarm module carries out alarm prompt according to the first alarm information to prompt a user to carry out manual dust removal on the condenser, such as intractable dust which is still not loose due to vibration on the condenser, and prompts the user to carry out manual dust removal.
The first collected voltage, the second collected voltage and the third collected voltage are only used for distinguishing voltage values corresponding to the wind speed collectors at different moments, specifically, the first collected voltage is a voltage value corresponding to the wind speed collector before dust removal after the air conditioner is started to operate, and whether the condenser is subjected to dust removal is judged according to the first collected voltage; the second collected voltage is a voltage value corresponding to the wind speed collector after each dust removal treatment so as to judge whether to exit the dust removal process of the condenser according to the second collected voltage; the third collected voltage is a voltage value corresponding to the wind speed collector when the preset times are reached, namely, the second collected voltage when the preset times are reached, so that which alarm information, such as the first alarm information or the second alarm information, is generated according to the third collected voltage.
In addition, if the third acquisition voltage is smaller than a preset first voltage threshold value, controlling the air conditioner to stop, and generating second alarm information; and sending the second alarm information to the alarm module so that the alarm module carries out alarm prompt according to the second alarm information to prompt a user to check whether the condenser is blocked or not. And in the process of repeatedly dedusting the condenser according to the dedusting mode, if the third acquired voltage acquired after each dedusting is over is not smaller than a preset second voltage threshold value, the dedusting of the condenser is stopped.
