Detailed Description
In order to make the technical solutions of the present invention better understood, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
It should be noted that the terms "first," "second," and the like in the description and claims of the present invention and in the drawings described above are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the invention described herein are capable of operation in sequences other than those illustrated or described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
In view of the above problems, some solutions exist, for example, a control method of an air purifier, a control system of an air purifier, and an air purifier are proposed in the prior art; wherein, the air purifier comprises a plasma generator and a PM2.5 sensor; specifically, the control method of the air purifier comprises the following steps: the method comprises the steps of obtaining indoor PM2.5 concentration detected by a PM2.5 sensor, controlling working parameters of the plasma generator according to the indoor PM2.5 concentration by combining the prestored corresponding relation between the voltage of the plasma generator and the output ratio of clean air and the ozone accumulation amount, and solving the technical problem that ozone exceeds the standard due to a plasma field on a high-voltage ion purifier on the premise of hardly increasing cost because an ozone reducing agent is not needed to be used for avoiding generating ozone and an ozone sensor is not needed. For another example, a control method of an air conditioner is also proposed in the prior art, the air conditioner includes an ionizer, and the control method includes: acquiring the existence information of a human body; acquiring the actual indoor air quality; and, when a human body exists, controlling the working voltage of the ionizer according to the difference between the actual air quality and the set air quality, wherein the working voltage does not exceed the rated maximum voltage; when no human body exists, the ion generator is controlled to operate at the rated highest voltage; the control method controls the ion generator to operate at the rated maximum voltage when no human body exists in a room so that the quantity of ionized air and the quantity of generated ozone of the ion generator can have a good sterilization effect, and controls the ion generator to operate at the working voltage not exceeding the rated maximum voltage when the human body exists in the room so that the ionized air and the generated ozone of the ion generator have little harm to the human body.
However, the above technical solutions only control the high voltage power supply to prevent the ozone from exceeding the standard, and cannot optimize the performance of the air sterilizer.
The applicant has found through research that the load characteristics of the dust-cleaning and collecting assembly of the air sterilizer can be roughly divided into the following sections: 1) no load: almost no current is output, and the power supply is in a power output state close to 0; 2) a power increasing area: in this stage, the output high voltage (for example, 8KV) is kept stable, and as the load gradually increases to the rated load, the current increases and the power gradually increases; 3) a constant power region: the output power is kept constant at this stage, the output high voltage is gradually reduced from 8KV along with the increase of the load, and the current is continuously increased; 4) a power reduction area: at the moment, the load of the high-voltage power supply is greatly higher than the rated load, and power reduction treatment is needed to inhibit the increase of the ozone generation rate; 5) overload: and when the load is overlarge, the power supply enters a protection state. Fig. 1 is a schematic diagram of a power-load curve change according to an embodiment of the present invention, and as shown in fig. 1, the output power is changed in a curve according to the load change.
In addition, according to the characteristic description of each section of the power curve, the high-voltage power supply can ensure that the performance is not reduced under the condition of small load, the reasonable control of the power increasing area is particularly important, and the generation of ozone can be effectively inhibited. In order to effectively solve the problem that the micro-ignition of the dust collecting component of the air sterilizer can cause the ozone to be obviously increased and exceed the national standard when dust is collected or foreign matters exist; the present application provides a control method and device for an air sterilizer, and an air sterilizer, which will be described in detail below.
Example 1
In accordance with an embodiment of the present invention, there is provided a method embodiment of a control method for an air sterilizer, it is noted that, for application to a power augmentation zone of an air sterilizer, the steps illustrated in the flowchart of the drawings may be performed in a computer system such as a set of computer executable instructions, and that, while a logical order is illustrated in the flowchart, in some cases the steps illustrated or described may be performed in an order different than that illustrated herein.
Fig. 2 is a flowchart of a control method of an air sterilizer according to an embodiment of the present invention, as shown in fig. 2, the control method of an air sterilizer including the steps of:
step S202, acquiring preset electrical parameters of a high-voltage generating circuit of the air sterilizer.
Optionally, the predetermined electrical parameters may include, but are not limited to: rated current value, rated duty cycle, maximum current value, rated voltage value.
In an alternative embodiment, obtaining predetermined electrical parameters of a high voltage generating circuit of an air sterilizer comprises: acquiring a storage path of the air sterilizer; the predetermined electrical parameter is read from the predetermined storage medium based on the storage path.
For example, in the above predetermined electrical parameters include: in the case of the rated current value, the rated duty ratio and the rated voltage value, the rated duty ratio Ds and the rated current value I may be setPROAnd the rated voltage value is recorded in a FLASH Memory or a special Memory chip of the chip, so that the data is not lost when the power is off and is read out after the power is on, and the reliability of the air sterilizer is improved.
In an optional embodiment, before reading the predetermined electrical parameter from the predetermined storage medium based on the storage path, the control method of the air sterilizer further comprises: determining the initial dust collection assembly as a rated load, and detecting the electrical parameters of the high-voltage generation circuit under the rated load to obtain a detection result, wherein the initial dust collection assembly is a dust collection assembly which is used for the first time after leaving a factory; under the condition that the detection result shows that the high-voltage electrode and the collector of the high-voltage generating circuit reach the rated voltage value, acquiring the rated duty ratio of a metal oxide semiconductor field effect transistor (MOS) on the high-voltage generating circuit and the rated current value under the rated voltage; determining a rated voltage value of the high-voltage generating circuit based on rated electrical parameters of the air sterilizer; the rated duty ratio, the rated current value, and the rated voltage value are determined as predetermined electrical parameters, and the predetermined electrical parameters are stored to a predetermined storage medium.
It should be noted that, because the tungsten filament and the collector are made with some errors, the loading parameters of each plate are different.
For example, in the embodiment of the present invention, a certain brand new dust collecting component may be used as a rated load, when a power supply is connected to a brand new pole plate for the first time, the power supply will perform self-test first, specifically, under the corresponding load condition, the voltage value is monitored through voltage feedback, and the load current value is monitored through the current detection circuit; when the high-voltage electrode and the collector reach rated voltage and normally operate, the duty ratio Ds of the MOS tube of the high-voltage generating circuit and the real-time load current I at the moment can be recordedPROThese two values are recorded as nominal values.
Step S204, determining that the high voltage generating circuit enters a power increasing area.
In an alternative embodiment, determining that the high voltage generating circuit enters the power boost region comprises: and when the air sterilizer is detected to be electrified, determining that the high-voltage generating circuit enters a power increasing area.
For example, after the load air sterilizer is powered on, i.e., enters the power boost region, as shown in FIG. 1, the slope of the power-load curve is changed; when the load air sterilizer is not electrified, the load air sterilizer is in an idle state; in addition, as can be seen from fig. 1, the load varies with the variation of the output power, and specifically, experiences no-load region, power increasing region, constant power region, power decreasing region, and overload. When the power supply keeps stable output high voltage (for example, 8KV), the duty ratio is equal to Ds and the output current is greater than or equal to IPRO, the power increasing area is judged to enter the constant power area; when an instant power increasing point occurs in the constant power region, the electrical parameters of the high-voltage generating circuit are adjusted, so that the working state of the power supply enters a power reducing region; when the electrical parameter is adjusted to a certain degree, the process state of the power supply may enter an overload state.
And step S206, controlling the actual electrical parameter of the high-voltage generating circuit based on the preset electrical parameter in the power increasing area so as to control the operation of the air sterilizer.
From the above, in the embodiment of the present invention, the predetermined electrical parameters of the high voltage generating circuit of the air sterilizer are obtained; determining that the high-voltage generating circuit enters a power increasing area; the actual electrical parameters of the high-voltage generating circuit are controlled in the power increasing area based on the preset electrical parameters to control the operation of the air sterilizer, so that the aim of improving the flexibility of the control of the output power of the air sterilizer by adjusting the electrical parameters of the high-voltage generating circuit of the air sterilizer in real time in the power increasing area is fulfilled, and the technical effects of improving the reliability and the performance of the air sterilizer are achieved.
Therefore, the control method of the air sterilizer provided by the embodiment of the invention further solves the technical problems that the output power of the air sterilizer is not flexibly controlled and the performance of the air sterilizer cannot reach the best in the related art.
In the power increasing region, the variation trend of each parameter of the power supply is to maintain the output high voltage (for example, 8KV), and as the load is gradually increased to the rated load, the current is increased, and the power is also gradually increased. As the load is gradually increased from a very small load (e.g., 500M Ω equivalent load) to a rated load (e.g., 80M Ω equivalent load). The control of the electrical parameters of the high voltage generating circuit also requires adjustment, in particular, the voltage as well as the current can be adjusted. The details will be described below.
In one aspect, in an alternative embodiment, controlling an actual electrical parameter of the high voltage generating circuit based on a predetermined electrical parameter in the power boost region comprises: driving the high-voltage generating circuit by using a rated duty ratio in the preset electrical parameters, and detecting the output voltage value of the high-voltage generating circuit in real time; and when the output voltage value is determined to be larger than the rated voltage value, driving the high-voltage generating circuit by using a first duty ratio until the output voltage value of the high-voltage generating circuit reaches the rated voltage value, wherein the first duty ratio is smaller than the rated duty ratio.
In this embodiment, the high voltage generating circuit may be driven at the rated duty ratio Ds, and thus, when the voltage detecting circuit detects that the output voltage of the high voltage generating circuit is greater than the rated voltage value, the duty ratio may be decreased until the voltage value of the high voltage generating circuit reaches the rated voltage value, and each different load may correspond to a different duty ratio.
In another aspect, controlling an actual electrical parameter of a high voltage generating circuit based on a predetermined electrical parameter in a power increasing region comprises: driving the high-voltage generating circuit by using a second duty ratio, and detecting the output voltage value of the high-voltage generating circuit in real time, wherein the second duty ratio is smaller than the rated duty ratio; and when the output voltage value is determined to be smaller than the rated voltage value, increasing a second duty ratio, and driving the high-voltage generating circuit by using the increased second duty ratio until the output voltage value reaches the rated voltage value.
In this embodiment, the high voltage generating circuit may be driven with a smaller duty ratio, and if the output voltage of the high voltage generating circuit fed back by the voltage detecting circuit is smaller than the rated voltage value at this time, the duty ratio is increased until the output voltage reaches the rated voltage value; it should be noted that the duty cycle can only be increased up to the nominal duty cycle.
In an alternative embodiment, controlling the actual electrical parameter of the high voltage generating circuit based on the predetermined electrical parameter in the power increasing region comprises: when the increased second duty ratio is determined to reach the rated duty ratio, detecting the actual current value of the air sterilizer in real time; and when the actual current value is lower than the rated current value, adjusting the actual voltage value of the high-voltage generating circuit.
In this embodiment, when the duty ratio is increased to the rated duty ratio, and it is monitored that the real-time load current is lower than the rated current value, the above adjustment of the voltage value may be performed; and if the real-time load current value is monitored to be larger than or equal to the rated current value, the power supply enters the constant power area control.
In summary, in the embodiment of the present invention, the control manner of the power increasing region in the complete control cycle of the air sterilizer can be described, so that the high voltage power supply can work under a small load condition to ensure that the performance is not reduced.

The control device of the air sterilizer will be explained below.

A determination unit 33 for determining that the high voltage generation circuit enters the power increasing region.
And a control unit 35 for controlling an actual electrical parameter of the high voltage generating circuit based on a predetermined electrical parameter in the power increasing region to control the operation of the air sterilizer.
