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 view showing a load characteristic of a dust collecting and purifying assembly of an air sterilizer according to an embodiment of the present invention, and the output power is varied in a curve as shown in fig. 1.
In addition, according to the characteristic description of each section of the power curve, the reasonable control of the constant power 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 method and apparatus for controlling output power of 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 an output power control method for an air sterilizer, it is noted that, for application to a constant power 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 an output power control method of an air sterilizer according to an embodiment of the present invention, as shown in fig. 2, the output power 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.
The predetermined electrical parameters include: obtaining the preset electrical parameters of the high voltage generating circuit of the air sterilizer under the conditions of the rated current value, the rated duty ratio and the maximum current value, wherein the preset electrical parameters comprise: 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 the maximum current value of the high-voltage generating circuit; the nominal duty cycle, the nominal current value and the maximum current value are determined as predetermined electrical parameters.
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 recordedPRORecording these two values as nominal values; as the load continues to increase, the current continues to increase, but the current cannot be allowed to increase indefinitely (excessive current will cause the ozone production rate to rise substantially), so a current maximum IMAX also needs to be preset.
In an alternative embodiment, after obtaining the predetermined electrical parameter of the high voltage generating circuit of the air sterilizer, the output power control method of the air sterilizer may further include: the predetermined electrical parameter is stored to a predetermined storage medium.
For example, the duty ratio Ds and the currents IPRO and IMAX may be recorded in a FLASH Memory of the chip or a special Memory chip, so as to ensure that data is not lost when power is off and read out after power is on, thereby improving the reliability of the air sterilizer.
Step S204, determining that the air sterilizer enters a constant power zone based on the predetermined electrical parameter.
Fig. 3 is a load-power curve of a high-voltage power supply according to an embodiment of the present invention, and as shown in fig. 3, the load varies with the output power, and specifically, the load experiences a no-load region, a power-increasing region, a constant power region, a power-decreasing region, and an overload. In the embodiment of the present invention, the control of the constant power region is mainly described in detail. When the power supply keeps outputting high voltage (for example, 8KV) stably, the duty ratio is equal to Ds and the output current is greater than or equal to IPRO, the constant power region is judged to be entered at the moment.
Thus, in an alternative embodiment, determining that the air sterilizer enters the constant power zone based on predetermined electrical parameters comprises: determining that the power supply of the air sterilizer keeps outputting high voltage for a preset time duration at a preset high voltage value, and acquiring the current duty ratio and the current output current value of an MOS (metal oxide semiconductor) tube of a high voltage generating circuit; and when the current duty ratio is the same as the rated duty ratio and the current value is not less than the rated current value, determining that the air sterilizing machine enters a constant power area.
And step S206, acquiring the current value of the high-voltage generating circuit in real time in the output power increasing process of the high-voltage generating circuit.
In this embodiment, for the voltage control in the constant power region, the high voltage generation circuit can be driven with a constant duty ratio Ds, and as the load continues to increase, the output voltage slowly decreases, and the output current increases, so that the current value change needs to be monitored in real time at this stage.
It should be noted that, in the embodiment of the present invention, before acquiring the current value of the high voltage generating circuit in real time during the process of increasing the output power of the high voltage generating circuit, the method for controlling the output power of the air sterilizer further includes: the high voltage generating circuit is driven at a nominal duty cycle.
And step S208, determining the current power state of the high-voltage generating circuit based on the current value, and determining a control strategy corresponding to the current power state based on the current power state.
In an alternative embodiment, in one aspect, determining that the air sterilizer enters the constant power zone based on predetermined electrical parameters may include: determining that the power supply of the air sterilizer keeps outputting high voltage for a preset time duration at a preset high voltage value, and acquiring the current duty ratio and the current output current value of an MOS (metal oxide semiconductor) tube of a high voltage generating circuit; and when the current duty ratio is the same as the rated duty ratio and the current value is not less than the rated current value, determining that the air sterilizing machine enters a constant power area.
For example, when the output current is monitored to be greater than or equal to the maximum current IMAX, it is determined that the power supply current is too large, and the current needs to be reduced to suppress ozone generation, and the power supply enters a power reduction region, and the corresponding control method needs to be switched to.
In another aspect, determining a current power state of the high voltage generating circuit based on the current value and determining a control strategy corresponding to the current power state based on the current power state includes: under the condition that the current value is not less than the maximum current value, determining that the high-voltage generating circuit enters a power reduction area, and calling a control strategy corresponding to the power reduction area; and under the condition that the current value is smaller than the rated current, determining that the high-voltage generating circuit enters a power increasing area, and calling a control strategy corresponding to the power increasing area.
For example, when the high voltage generator is in the constant power region, if the load is smaller and the duty ratio is not changed, the output voltage is not changed and the output current is reduced, and when the output current is smaller than IPROAnd when the high-voltage generator drops into the power increasing area from the constant power area, switching to a corresponding control method.
And step S210, controlling the output power of the air sterilizer based on the control strategy.
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 air sterilizer enters a constant power zone based on predetermined electrical parameters; acquiring the current value of the high-voltage generating circuit in real time in the process of increasing the output power of the high-voltage generating circuit; determining the current power state of the high-voltage generating circuit based on the current value, and determining a control strategy corresponding to the current power state based on the current power state; the output power of the air sterilizer is controlled based on the control strategy, so that the output of the current is controlled by detecting the voltage value, the current value and other electrical parameters of the high-voltage generating circuit of the air sterilizer in a constant power area, the purpose of preventing the high-voltage generating circuit from generating abnormity is achieved, the rapid increase of ozone is effectively avoided, and the reliability and the performance of the air sterilizer are improved.
Therefore, the method for controlling the output power of the air sterilizer provided by the embodiment of the invention solves the technical problem that the output power of the air sterilizer is not reasonably controlled and the performance of the air sterilizer cannot reach the best in the related technology.
In summary, the output power control method of the air sterilizer provided by the embodiment of the invention is designed for the voltage and current change characteristics of the constant power region, and controls the current output by detecting the voltage and the current, thereby preventing the high voltage generator from working abnormally and avoiding the rapid increase of ozone. Also effectively solves the problem that the ozone is obviously increased or even exceeds the national standard because the dust collecting component generates micro-ignition when collecting dust or foreign matters exist.
