Compared with the prior art, the technical scheme of the invention has the following advantages:
1. the embodiment of the invention provides a control method of ionization purification equipment, wherein the ionization purification equipment comprises a purification module, and the purification module is used for adsorbing pollutants in air, and is characterized by comprising the following steps: acquiring the current working current of the purification module; judging whether the current working current is larger than a preset current threshold value or not; when the current working current is larger than the current threshold, acquiring the duration of the current working current larger than the current threshold; and when the duration that the current working current is greater than the current threshold is less than a preset duration threshold, reducing the working voltage of the purification module to a preset voltage.
According to the arrangement, when the current working current is detected to be larger than the current threshold, the phenomenon of continuous sparking is indicated, when the duration that the current working current is larger than the current threshold is detected to be smaller than the preset duration threshold, the trend of the phenomenon of continuous sparking is indicated, the working voltage of the purification module is reduced to the preset voltage, the working voltage is rapidly reduced, the current in the circuit of the purification module is adjusted, the large current during sparking is reduced to the working current in the normal range, and the phenomenon of continuous sparking in the current can be controlled.
Moreover, because a certain change relationship exists between the load voltage and the current of the purification module, when the load voltage of the purification module is not in the range of the corona voltage region, the volt-ampere characteristic curve between the load voltage and the current is relatively stable; when the load voltage of the purification module is within the range of the corona voltage area, the fluctuation range of the voltage-current characteristic curve between the load voltage and the current is large. Therefore, when the load voltage of the purification module is smaller or larger than the corona voltage, the load voltage fluctuates by the same magnitude, and the variation amplitude of the current is small. When the load voltage of the purification module is the corona voltage, the load voltage fluctuates by the same amplitude, and the variation amplitude of the current is large. In the prior art, the load voltage of the purification module is reduced to a certain extent, but the load voltage of part of the purification module is about corona voltage, so that the current fluctuation amplitude is large when the ignition phenomenon occurs. Therefore, in the embodiment of the invention, the combined action of the voltage and the current is combined, and compared with the current ignition detection method, the current can be accurately mastered, so that the current is used as a main detection means, the voltage is used as a main control means for regulation, the circuit can be accurately ensured to monitor the ignition condition and control continuous ignition, and the ionization purification equipment, namely the air purifier is protected.

In the embodiment of the invention, through the step of controlling the purification module to restart when the duration of the current working current greater than the current threshold is greater than or equal to the preset duration threshold, when the current working current is detected to be greater than the current threshold and the duration is greater than or equal to the preset time, it is indicated that the ignition phenomenon of the purification module continuously occurs, at the moment, the current in the circuit is large, the working voltage of the purification module is reduced to the preset voltage, so that the current cannot be reduced to the normal range, and the purification module needs to be powered off. In order to prevent the occurrence of the ignition phenomenon, which is caused by accidental factors, the purification module needs to be restarted, the interior of the purification module is completely powered off by restarting, and then the purification module is started to work.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.
In the description of the present invention, it should be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, e.g., as meaning either a fixed connection, a removable connection, or an integral connection; can be mechanically or electrically connected; the two elements may be directly connected or indirectly connected through an intermediate medium, or may be communicated with each other inside the two elements, or may be wirelessly connected or wired connected. The specific meanings of the above terms in the present invention can be understood in specific cases by a worker of ordinary skill in the art.
In addition, the technical features involved in the different embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.
The existing ignition detection method only adopts voltage detection and control or current detection and control alone, but for a purification module with a small load voltage, for example, the voltage is less than 8KV, most of the voltage in the market can be increased to more than 10KV, and for a purification module with a large voltage, when the voltage fluctuates, the voltage fluctuation of 100V belongs to large-range fluctuation, and large current fluctuation is easy to generate. Since the voltage of about 7KV and the current in this case are no longer suitable for ohm's law, and the current rises faster, the magnitude of the pressurization is smaller, and the current needs to be grasped more accurately. Therefore, one parameter cannot be precisely realized by voltage or current alone.
Specifically, because there is a certain variation relationship between the load voltage and the current of the purification module, and it is easy to generate a sudden change in the corona voltage of about 7.1KV, that is, the current variation amplitude of about 7.1KV is large under the same fluctuation amplitude of the load voltage, and the current variation amplitude is small before and after 7.1KV if the load voltage fluctuates with the same amplitude. Because the load voltage of most purification modules in the market is above 10KV, when the load voltage of the purification modules is above 10KV, if 100V voltage fluctuation occurs due to the ignition phenomenon, the corresponding current fluctuation is small, and for the purification modules with the load voltage less than 8KV, for example, 7KV, the current fluctuation is large when 100V voltage fluctuation occurs. Therefore, after the occurrence of the sparking phenomenon, only the voltage or only the current is detected, which easily causes the detection result to be inaccurate.
In the embodiment of the invention, the combined action of the voltage and the current is combined, when the load voltage of the purification module is less than 8KV, the current is accurately mastered, so that the current is used as a main detection means, the voltage is used as a main control means for regulation, the circuit can be accurately ensured to monitor the ignition condition and control continuous ignition, and the ionization purification equipment, namely the air purifier is protected.
Example 1
As shown in fig. 1, an embodiment of the present invention provides a control method for an ionization purification apparatus, where the ionization purification apparatus includes a purification module, and the purification module is configured to adsorb dust pollutants in air, where the pollutants may include dust, oil smoke, bacteria, viruses, and the like. The control method specifically comprises the following steps:
s1, obtaining the current working current of the purification module;
after the purification module of the ionization purification device is started to work, the working parameters of the purification module are monitored, for example, the voltage and the current of the whole circuit in the purification module can be monitored. In the embodiment of the invention, a current monitoring mode is adopted, and whether the purification module is in a normal working state or not can be known according to the change of the current.
S2, judging whether the current working current is larger than a preset current threshold value or not;
and matching a series of purification modules with a power supply in the early stage, obtaining the maximum current which can be reached when the purification modules operate under normal working voltage, and setting the maximum current as a preset current threshold. When the current working current exceeds the current threshold value, the ignition phenomenon of the purification module is considered to occur.
S3, when the current working current is larger than the current threshold, acquiring the duration of the current working current larger than the current threshold;
and when the current working current is larger than the current threshold value, the ignition phenomenon of the purification module is considered to occur. At the moment, the preset duration when the current working current is larger than the preset current is obtained, and whether the sparking phenomenon is continuous sparking or occasional intermittent sparking is judged according to the preset duration when the current working current is larger than the preset current. For the electric purification module, when large-particle dust pollutants enter, a short slight fire is occasionally struck once or twice, which is a normal phenomenon, but when continuous fire striking is occurred, the safety problem is solved. The continuous sparking phenomenon not only has potential safety hazard for users, but also can cause the influence of resetting of a controller of a circuit and even damage to components due to frequent sparking. In addition, the ignition phenomenon can generate high-concentration ozone, so that the power efficiency is completely wasted, and the efficiency of the purification module is reduced. In the embodiment of the present invention, the duration may be set between 0.1ms and 100 ms.
Of course, the specific duration time in the range of 0.1ms to 100ms may be changed by those skilled in the art, and the embodiment is only an example of the duration time range, but not a limitation, and can achieve the same technical effect.
And S4, when the duration that the current working current is greater than the current threshold is less than a preset duration threshold, reducing the working voltage of the purification module to a preset voltage.
When the obtained duration that the current working current is larger than the current threshold is smaller than a preset duration threshold, the phenomenon that the sparking happens is occasionally intermittent sparking and is normal. However, when the sparking phenomenon occurs, the current tends to rise suddenly in the circuit of the purification module, the large current may damage the components of the whole circuit, and the large current suddenly changing for a long time in the circuit may damage the circuit components of the purification module. Therefore, the working voltage of the purification module needs to be properly reduced, and the working current can be greatly reduced on the premise of ensuring the normal work of the purification module, so that the circuit components of the purification module are prevented from being damaged.
According to the arrangement, when the current working current is detected to be larger than the current threshold, the phenomenon of continuous sparking is indicated, when the duration that the current working current is larger than the current threshold is detected to be smaller than the preset duration threshold, the trend of the phenomenon of continuous sparking is indicated, the working voltage of the purification module is reduced to the preset voltage, the working voltage is rapidly reduced, the current in the circuit of the purification module is adjusted, the large current during sparking is reduced to the working current in the normal range, and the phenomenon of continuous sparking in the current can be controlled.
Moreover, because a certain change relationship exists between the load voltage and the current of the purification module, when the load voltage of the purification module is not in the range of the corona voltage region, the volt-ampere characteristic curve between the load voltage and the current is relatively stable; when the load voltage of the purification module is within the range of the corona voltage area, the fluctuation range of the voltage-current characteristic curve between the load voltage and the current is large. Therefore, when the load voltage of the purification module is smaller or larger than the corona voltage, the load voltage fluctuates by the same magnitude, and the variation amplitude of the current is small. When the load voltage of the purification module is the corona voltage, the load voltage fluctuates by the same amplitude, and the variation amplitude of the current is large. In the prior art, the load voltage of the purification module is reduced to a certain extent, but the load voltage of part of the purification module is about corona voltage, so that the current fluctuation amplitude is large when the ignition phenomenon occurs.
Therefore, in the embodiment of the present invention, the voltage and the current are combined, and the current has a large variation range because of the load voltage fluctuating with the same magnitude. Consequently through the accurate electric current of mastering to the realization uses the electric current as main detection means, uses voltage to adjust as main control means, can ensure that the circuit can monitor the condition of striking sparks and control continuous striking sparks accurately, thereby to ionization clarification plant, protect air purifier promptly.
Optionally, in some embodiments of the present invention, after step S3, the method further includes:
and S4, when the duration that the current working current is greater than the current threshold is greater than or equal to a preset duration threshold, controlling the purification module to restart.
When the duration that the obtained current working current is greater than the current threshold is greater than or equal to a preset duration threshold, the ignition phenomenon belongs to continuous ignition and is abnormal. When the ignition phenomenon occurs, the current has a tendency of rising suddenly in the circuit of the purification module, the large current can damage the components of the whole circuit, and the continuous ignition can further accelerate the damage of the circuit components of the purification module. Therefore, the purification module needs to be restarted, the interior of the purification module can be completely powered off, and circuit components of the purification module are prevented from being damaged. Meanwhile, in order to prevent the occurrence of the sparking phenomenon, which is caused by an accidental factor, the cleaning module needs to be restarted.
In the embodiment of the invention, through the step of controlling the purification module to restart when the duration of the current working current greater than the current threshold is greater than or equal to the preset duration threshold, when the current working current is detected to be greater than the current threshold and the duration is greater than or equal to the preset time, it is indicated that the ignition phenomenon of the purification module continuously occurs, at the moment, the current in the circuit is large, the working voltage of the purification module is reduced to the preset voltage, so that the current cannot be reduced to the normal range, and the purification module needs to be powered off. In order to prevent the occurrence of the sparking phenomenon which is caused by the accidental factor, the cleaning module needs to be restarted.
Specifically, in the embodiment of the present invention, step S4 includes:
s41, controlling the purification module to be closed, and obtaining the closing time of the purification module;
because ionization clarification plant, including a plurality of work modules in the air purifier promptly, the purification module is only one of work module in the air purifier, so after purification module closes, other work modules of air purifier are still working, for example air-out module, air inlet module, disinfection module etc.. After the purification module is closed, the closing time of the purification module is obtained.
S42, judging whether the closing time length reaches a preset time length or not;
if the ignition is caused by an accidental factor, other operation modules of the air purifier are likely to eliminate the accidental factor when the purification module is in a closed state. For example, large particle dust contaminants, after entering the purification module, cause a short circuit between two electrode plates of the purification module, causing a continuous sparking phenomenon of the purification module. When the purification module is in the closed state, large particle dust contaminants fall on the dust collecting plates and lose electric charge, and simultaneously lose the acting force of the two electrode plates on the dust collecting plates.
After the preset time, the wind generated by the air purifier can blow the large particle dust pollutants away from the original position very possibly, and the dust collecting plate can adsorb the large particle dust pollutants, so that the continuous occurrence of the ignition phenomenon caused by accidental factors can be avoided.
Of course, the preset time period may be determined according to the actual application, and may be, for example, a specific time within 1min to 5 min. The present embodiment is merely an example, and is not limited to the above embodiment, and may achieve corresponding technical effects.
S43, if yes, controlling the purification module to restart.
And when the closing time length reaches the preset time length, controlling the purification module to restart. The purge module is then restarted and it can be determined whether it was due to an accidental event.
Specifically, in the embodiment of the present invention, after step S4, the method further includes:
s5, acquiring the restart times;
after the restart of the purification module, the purification module needs to go through the steps again, and one time is added after the restart of the purification module.
S6, judging whether the restart times are greater than preset times or not;
through restarting many times, screening the reason that the phenomenon of striking sparks appears in the purification module, if restart number of times is less than or equal to and predetermines the number of times, explain that the reason that the phenomenon of striking sparks appears is that occasionally intermittent striking sparks, belongs to normal phenomenon. If the restarting times are more than the preset times, the ignition phenomenon is not an accidental phenomenon, but a short circuit caused by the damage inside the purification module is caused, or the purification module has too much dust and needs to be cleaned.
Of course, the preset number of times may be determined according to the actual application, for example, the number may be set to 5 times. The present embodiment is merely an example, and is not limited to the above embodiment, and may achieve corresponding technical effects.
And S7, if so, controlling the purification module to be closed, and resetting the restart times.
If the restart times are actually greater than the preset times, the purification module is directly controlled to be closed, and the restart times are reset, so that circuit components of the purification module can be protected from being damaged.
Optionally, after step S7, the method further includes:
and S8, sending out an electric signal for representing the fault.
If the restarting times are more than the preset times, the ignition phenomenon is not an accidental phenomenon, but a short circuit caused by the damage inside the purification module is caused, or the purification module has too much dust and needs to be cleaned. Therefore, an electric signal for representing a fault needs to be sent, so that a user can know the fault in time, and the air purifier is prevented from bringing potential safety hazards.
Optionally, after step S6, the method further includes:
and S9, if not, executing the step of acquiring the current working current of the purification module.
If the restarting frequency is less than or equal to the preset frequency, the reason that the sparking phenomenon occurs is occasional intermittent sparking and belongs to a normal phenomenon, and the step is continuously returned to detect again.
Optionally, after step S2, the method further includes:
and S10, when the current working current is less than or equal to the current threshold value, executing the step of acquiring the current working current of the purification module.
And when the current working current is less than or equal to the current threshold, indicating that the purification module is in a normal working state, and continuously returning to the step for re-detection.
