Referring to fig. 3, an embodiment of the air purification control method of the present application is presented. In this embodiment, the air purification control method includes:
And S10, controlling the power supply module to input a changed electric signal to the filtering device, wherein the filtering device generates a changed electric field after inputting the changed electric signal.
The electrical signal may specifically comprise a voltage signal or a current signal, etc. The changing electrical signal may specifically refer to a numerical changing electrical signal and/or a directional changing electrical signal. When the electric signal input by the power supply module to the filtering device is an electric signal with a numerical value change, the filtering device generates an electric field with an electric field force change; when the electric signal input by the power supply module to the filtering device is an electric signal with direction changing, the filtering device generates an electric field with direction changing.
The electric signal input by the power supply module to the filtering device can be an electric signal which changes according to a certain rule, or an electric signal which changes irregularly, or an electric signal which changes continuously, or an electric signal which changes intermittently, and the like.
Specifically, when the control power module inputs the first electrical signal to the filtering device, if the set condition is reached, the control power module may input the second electrical signal (different from the first electrical signal) to the filtering device. The setting condition here may be that the input time period including the first electric signal reaches the setting time period, the setting instruction is received, the operation of the filtering device reaches the setting state, or the like.
According to the air purification control method provided by the embodiment of the invention, the power supply module is controlled to input the changed electric signals to the filtering device so that the filtering device generates the changed electric field, the changed electric field can enable charged particles passing through the filtering device to no longer move in a fixed rule, the irregular movement can improve the Brownian movement among the particles so that the particles can be more easily moved to the electrodes to be adsorbed, even the particles can be moved to different electrodes to be adsorbed, and the particles can be not accumulated on the fixed electrodes in a large quantity, so that the filtering device is more beneficial to adsorbing the charged particles in the air, and the purification efficiency of the air purification equipment is improved.
Further, based on the above embodiment, another embodiment of the air cleaning control method of the present application is proposed. In this embodiment, the electrical signal includes a voltage signal, and referring to fig. 4, the step of controlling the power module to input a variable electrical signal to the filtering device in step S10 includes:
step S11, controlling the power supply module to output a voltage signal with a changed voltage value so as to input the changed electric signal to the filtering device.
The intermittent or continuous control power supply module outputs voltage signals with voltage values changing in a decreasing trend, increasing trend or random change, and the filtering device generates an electric field with electric field force changing after receiving the voltage signals with voltage values changing.
Specifically, in order to ensure the effectiveness of the purifying function of the filtering device and ensure the electrical safety, a voltage interval may be provided, when the input voltage value of the filtering device is smaller than the value in the voltage interval, the purifying effect of the filtering device is poor, and when the input voltage value of the filtering device is larger than the value in the voltage interval, the breakdown voltage between the electrodes may be exceeded, so that the filtering device is damaged, based on the breakdown voltage, the pollutant concentration in the working space of the air purifying device may be obtained, and the lower limit value of the voltage interval is determined based on the pollutant concentration; the minimum distance between the first electrode and the second electrode in the filtering device is obtained (when the first electrode comprises the first sub-electrode and the second electrode comprises the second sub-electrode, the distance is the distance between the adjacent first sub-electrode and second sub-electrode), and the upper limit value of the voltage interval is obtained according to the obtained distance. Wherein, the larger the acquired pollutant concentration, the larger the lower limit value; the larger the acquired pitch, the larger the upper limit value of the voltage interval. In this embodiment, the voltage interval is specifically [ -2000V, -15000V ].
Acquiring the voltage interval, and controlling the power module to output a voltage signal with a voltage value changing based on the voltage interval so as to input a changing electric signal to the filtering device; the voltage values of the changed voltage signals are all within the voltage interval.
In this embodiment, by inputting a voltage signal with a voltage value that varies to the filtering device, the filtering device generates an electric field with a varying electric field force, and the brownian motion of the charged particles in the air is promoted under the effect of the varying electric field force, so that the charged particles are easier to move to the adsorption electrode to be adsorbed, thereby realizing the improvement of the purification efficiency.
Further, in this embodiment, the step of controlling the power module to output the voltage signal with the changed voltage value includes:
step S111, when the voltage value of the voltage signal does not reach the first threshold, controlling the power module to output a voltage signal with a voltage value changing in an increasing trend;
The larger the voltage value input by the power supply module to the filtering device is, the larger the electric field force generated by the filtering device is, and the stronger the effect of adsorbing charged particles is.
In the process of controlling the voltage signal of which the output voltage value of the power supply module changes in an increasing trend, when the deviation between the voltage value of the voltage signal and the first threshold value is larger than or equal to a set threshold value, controlling the voltage signal of which the output voltage value of the power supply module changes in an increasing trend based on a first change rate; when the deviation between the voltage value of the voltage signal and the first threshold value is smaller than the set threshold value, controlling the power supply module to output the voltage signal with the voltage value changing in an increasing trend based on a second change rate; wherein the second rate of change is less than the first rate of change. The deviation amount can be set according to actual requirements, for example, 30% of the first threshold can be used as the deviation amount. That is, the closer the voltage value of the voltage signal is to the first threshold value, the slower the rate at which the voltage value changes; the greater the deviation of the voltage value of the voltage signal from the first threshold value, the faster the rate at which the voltage value changes.
The first threshold is a maximum voltage value allowed to be reached by the voltage signal, and may specifically be an upper limit value of the voltage interval. The voltage value of the voltage signal is continuously increased, and if the voltage value is smaller than the first threshold value, the step S111 can be maintained; when the voltage value of the voltage signal reaches the first threshold value, step S112 is performed.
Step S112, controlling the power module to output a voltage signal with a voltage value changing in a decreasing trend.
When the voltage value is greater than or equal to the first threshold value, the controllable power supply module inputs a voltage signal with the voltage value smaller than the first threshold value to the filtering device, and the voltage value of the input voltage signal changes in a decreasing trend. Wherein, in the process of decreasing the voltage value, when the voltage value decreases to be less than or equal to the second threshold value (the second threshold value is less than the first threshold value, which may be specifically the lower limit value of the voltage interval), step S111 may be executed back; when the voltage value is greater than the second threshold value, the step S112 may be maintained, so that the electric field generated by the filtering device may be continuously changed during the operation of the air cleaning apparatus.
In this embodiment, through step S111 and step S112, when the voltage value does not reach the first threshold, the voltage value of the voltage signal changes in an increasing trend, which is favorable for further improving the purifying efficiency of the air purifying device, and when the voltage value reaches the first threshold, the voltage value of the voltage signal changes in a decreasing trend, which is favorable for ensuring the electrical safety of the air purifying device. When the input voltage value is a voltage value with an increasing trend, the change rate is set based on the difference between the voltage value of the current voltage signal and the first threshold value, and when the deviation is large, the voltage value of the voltage signal is increased by adopting a larger first change rate, so that the filtering device can quickly reach a state with higher purification efficiency; when the deviation amount is smaller, the voltage value of the voltage signal is increased by adopting a smaller second change rate, so that the time for maintaining the filter device in a state with better purification efficiency is increased, the adsorption effect of the filter device on charged particles is further improved, and the purification efficiency of the air purification equipment is further improved.
Further, based on the step S111 and the step S112, before the step S112, the method further includes:
Step S101, when the voltage value of the voltage signal reaches a first threshold value, starting timing;
If the time duration is less than or equal to the set time duration, executing step S102; if the timing time is longer than the set time, step S112 is executed. The specific value of the set duration can be determined according to actual conditions. For example, it may be determined based on a minimum distance between the first electrode and the second electrode in the filter device, the smaller the distance, the smaller the set time period.
Step S102, controlling the power supply module to output a voltage signal with a voltage value being the first threshold value;
In this embodiment, the greater the voltage value of the voltage signal, the greater the electric field force is, the more favorable to adsorbing charged particles, and the duration of the purification efficiency of the filtering device in the optimal state is increased by the cooperation of step S111, step S101, step S102 and step S112, so as to further improve the purification efficiency, and the voltage value is reduced after reaching the set duration, thereby avoiding the risk of high voltage breakdown caused by continuous high voltage and ensuring electrical safety.
Further, based on any one of the above embodiments, a further embodiment of the air purification control method of the present application is provided. In this embodiment, the electrical signal includes a voltage signal, and referring to fig. 5, the step of controlling the power module to input a changed electrical signal to the filtering device in the step S10 further includes:
And step S12, controlling the power supply module to output a voltage signal with the voltage direction changed so as to input the changed electric signal to the filtering device.
The voltage direction herein specifically refers to a direction in which a high voltage formed when a voltage signal output from the power supply module is loaded in the filtering device is directed to a low voltage. Specifically, when the voltage signal is input into the filtering device in the first voltage direction, the first electrode of the filtering device is a high voltage end, and the second electrode of the filtering device is a low voltage end, namely, the direction of driving the high voltage of the filtering device to point to the low voltage is the direction of the voltage signal of the first electrode to point to the second electrode, and the direction of driving the high voltage of the filtering device to point to the low voltage is the first voltage direction; when the voltage signal is input into the filtering device in the second voltage direction, the second electrode of the filtering device is a high voltage end, and the first electrode of the filtering device is a low voltage end, namely, the direction of driving the high voltage of the filtering device to point to the low voltage is the direction of the voltage signal of the second electrode to point to the first electrode is the second voltage direction. The voltage direction of the voltage signal output by the power supply module may be changed randomly or when a setting instruction is detected.
Controlling the power module to input a voltage signal with a voltage direction changing to the filtering device refers to controlling the power module to switch a current high-voltage signal output end from one electrode of the filtering device to the other electrode. For example, the negative high voltage signal output end of the power supply module is switched from being connected with the first electrode to being connected with the second electrode, so that the negative high voltage is switched from the first electrode input to the second electrode input; or the negative high voltage signal output end of the power supply module is switched from being connected with the second electrode to being connected with the first electrode, so that the negative high voltage is switched from the second electrode input to the first electrode input.
Specifically, step S12 includes:
And step S121, when the voltage direction of the voltage signal is the first voltage direction, if a setting command is detected, controlling the power module to switch the electrode connection mode with the power module, so that the voltage direction of the voltage signal input by the power module to the filtering device is switched from the first voltage direction to the second voltage direction.
The setting instruction here may be specifically a start-up instruction of the air cleaning apparatus or other instructions input by the user, or the like. Specifically, the third electrode is defined as the positive electrode of the power module, and the fourth electrode is defined as the negative electrode of the power module, wherein the positive electrode is grounded. When the air purification equipment is in an on state, the positive electrode of the control power supply module is connected with the first electrode of the filtering device, the negative electrode of the control power supply module is connected with the second electrode of the filtering device, and an input electric signal is in a first voltage direction, so that after the electric signal is input into the filtering device, the first electrode is a high-voltage end (namely a zero electrode), the second electrode is a low-voltage end (namely a negative high voltage), and an electric field direction formed by the filtering device is that the first electrode points to the second electrode; in the process or after the air purification equipment is switched from the on state to the off state, the voltage direction of a voltage signal output by the power supply module is a first voltage direction, when a set instruction (such as a start instruction) is detected, the positive electrode of the power supply module is controlled to be switched from being connected with a first electrode of the filtering device to being connected with a second electrode of the filtering device, meanwhile, the negative electrode of the power supply module is controlled to be switched from being connected with the second electrode of the filtering device to being connected with the first electrode, an input electric signal is switched from the first voltage direction to the second voltage direction, so that after the electric signal is input into the filtering device, the second electrode is a high voltage end (namely a zero electrode), the first electrode is a low voltage end (namely a negative high voltage), and the electric field direction formed by the filtering device is that the second electrode points to the first electrode.
It should be noted that, if the air purifying apparatus is in the on state but the setting command is not detected, the power module may be controlled to synchronously execute step S11 in the above embodiment while maintaining the output of the voltage signal in the first voltage direction; or if the air purifying apparatus is in the off state and the setting instruction is the power-on instruction, step S11 may be performed after step S121 until the air purifying apparatus is turned off. That is, step S11 is performed when the voltage direction of the voltage signal output from the power module is constant and the air cleaning apparatus is in the on state.
In this embodiment, the power supply module is controlled to input an electrical signal with a voltage direction changing to the filtering device, so that an electric field with a changing electric field direction is generated in the filtering device, the electrode which can be used for adsorbing the particulate matters in the filtering device is increased due to the changing electric field direction, the range of the filtering device for adsorbing the particulate matters is increased, the particulate matters are prevented from accumulating on a single electrode to affect the adsorption effect, the adsorption effect of the two electrodes on the particulate matters is effectively exerted, and therefore the effective improvement of the purification efficiency is achieved.
Further, when the power module inputs an electric signal in a second voltage direction to the filtering device, if a setting instruction is detected, the power module can be controlled to switch an electrode connection mode with the power module, so that the voltage direction of the voltage signal input by the power module to the filtering device is switched from the second voltage direction to the first voltage direction, two electrodes in the filtering device can be alternately used as adsorption electrodes, particles are prevented from being gathered at the same electrode, and the cleaning frequency of a filter screen can be reduced while the cleaning efficiency is improved. The specific embodiment of switching from the second voltage direction to the first voltage direction can be analogically referred to the specific embodiment of switching from the first voltage direction to the second voltage direction, and will not be described herein. When the setting command is detected, the power module can be controlled to maintain outputting the voltage signal in the same voltage direction (for example, maintaining outputting the voltage signal in the first voltage direction or maintaining outputting the voltage signal in the second voltage direction) until the next time when the setting command is detected again.
In addition, the embodiment of the invention also provides a readable storage medium, wherein the readable storage medium is stored with an air purification control program, and the air purification control program realizes the relevant steps of any embodiment of the air purification control method when being executed by a processor.
