Detailed Description
Embodiments of the present invention will be described in detail below, the embodiments described with reference to the drawings being illustrative, and the embodiments of the present invention will be described in detail below.
The working principle of the anion generator is that low-voltage direct current is converted into high-frequency alternating current through an oscillating circuit, wherein the frequency range of the high-frequency alternating current is 20kHz-800kHz, the high-frequency alternating current is boosted through a transformer with a high turn ratio, and is boosted into negative high voltage such as-4 kv-10 kv after voltage doubling treatment of a voltage doubling circuit; a negative high voltage is applied to a point discharge end such as a discharge needle, a carbon brush, a copper wire, etc., to perform point discharge, thereby generating negative ions by the point discharge. Based on the working principle, the inventor researches and discovers that the discharge time of the anion generator can influence the anion generation rate of the anion generator, and further influence the anion generator to generate anion concentration.
The method for adjusting the negative ion concentration of the embodiment of the present invention will be explained below.
An anion concentration adjusting method according to an embodiment of the present invention, which is applicable to an air cleaning apparatus that may include an anion generator for generating anions, is described below with reference to fig. 1 to 4. The method can adjust the discharge time of the anion generator according to the operation mode of the air purification equipment, thereby steplessly adjusting the anion generation rate, realizing the accurate adjustment of the anion concentration, controlling the anion generator to accurately adjust to the corresponding anion concentration according to the function mode required by a user, satisfying the user requirement and improving the user experience.
As shown in fig. 1, the negative ion concentration adjustment method of the embodiment of the invention includes at least step S1, step S2, and step S3.
In step S1, the ionizer is activated after receiving the activation command of the ionizer.
In an embodiment, the start command may be issued by the air purification apparatus. In some examples, when a user has an air purification demand, the air purification device is manually turned on, and at this time, the air purification device sends a starting instruction, and the anion generator is started after receiving the starting instruction. In other examples, the air purification device may be configured to periodically send a start instruction, that is, the air purification device sends a start instruction to start the anion generator at intervals, so that the anion generator may be automatically started periodically to purify air without manual operation of a user, thereby improving intelligence of the air purification device.
In other words, the air cleaning apparatus may transmit the activation command to the ionizer according to a set period, i.e., transmit the activation command every set period, to activate the ionizer. In a specific embodiment, for example, a timer is provided in the air purification apparatus, the timer is controlled to start every set period, and after the timer is started, a start instruction is sent to start the anion generator according to a change of a clock signal of the timer, for example, when the clock signal becomes zero. Through setting up the timer, control anion generator and start, need not anion generator and be in the on-state all the time to effectively reduce the energy consumption.
In step S2, the operation mode of the air cleaning apparatus is acquired.
In the embodiment, the air purification apparatus is configured with a plurality of operation modes, such as a refreshing mode, a purification mode, a sterilization mode, and the like, for example, after the anion generator is activated, the operation mode in which the air purification apparatus is currently located is determined, the operation mode is obtained, and step S3 is executed.
In a specific embodiment, the current operation mode of the air purification apparatus may be determined manually by a user, or may be a default operation mode when the air purification apparatus is powered on. For example, when the user turns on the air purification device, the user manually selects a required operation mode, such as a refreshing mode or a purification mode, according to actual requirements; or, when the user starts the air purification device, the user does not receive the operation mode required by selection, at this time, the air purification device selects a default operation mode, and the default operation mode is preset, namely, after the air purification device is started, the default operation mode is a purification mode or a refreshing mode.
And step S3, adjusting the discharge time of the anion generator according to the operation mode of the air purification equipment so as to adjust the concentration of the anions generated by the anion generator.
Specifically, since the concentration of negative ions can be determined by the negative ion generation rate, the negative ion generation rate is influenced by the discharge time of the negative ion generator under the premise that the discharge voltage and the number of discharge terminals are constant. For example, when the discharge time of the anion generator is longer, the faster the anion generation rate is, the higher the corresponding concentration of the generated anions is; conversely, when the discharge time of the anion generator is shorter, the slower the anion generation rate is, the smaller the anion concentration is correspondingly generated. Therefore, according to the embodiment of the invention, the discharge time of the negative ion generator is correspondingly adjusted according to the current operation mode of the air purification equipment, so that the generation rate of negative ions is adjusted in a stepless manner, and the accurate adjustment of the concentration of the negative ions is realized.
In the embodiment, the operation modes of the air purification device are different, the discharge time of the corresponding negative ion generator is different, and the concentration of the corresponding generated negative ions is different. Specifically, the corresponding required discharge time of the anion generator in the operation mode is determined by determining the operation mode of the air purification equipment, so that the actual discharge time of the anion generator is adjusted to the corresponding required discharge time in the operation mode, the anion generation rate is adjusted according to the corresponding required discharge time, and the accurate adjustment of the anion concentration is realized.
The current operation mode of the air purification equipment is determined, and the corresponding required discharge time of the anion generator in the mode is determined, so that the actual discharge time of the anion generator is adjusted on the premise that the discharge voltage and the number of discharge ends are certain, the corresponding required discharge time of the anion generator in the mode is adjusted, the anion generation rate is adjusted in a stepless mode, and the concentration of anions generated by the anion generator is accurately adjusted.
In a specific embodiment, the air cleaning device is, for example, an air cleaner or an air conditioner having an air cleaning function, i.e. the air conditioner is provided with an anion generator.
The air purification device is taken as an air conditioner for explanation, that is, when a user opens the air conditioner and selects an air purification function, the air conditioner sends a starting instruction to start the anion generator, after the anion generator is started, the current operation mode of the air conditioner is determined, for example, a sterilization mode, the discharge time required by the anion generator corresponding to the sterilization mode is determined according to the sterilization mode, and then the actual discharge time of the anion generator is adjusted to reach the discharge time required by the anion generator corresponding to the sterilization mode, so that the adjustment of the anion concentration generated by the anion generator is realized, and the anion concentration meets the corresponding anion concentration in the sterilization mode, thereby meeting the user requirements and improving the user experience.
Therefore, according to the negative ion concentration adjusting method provided by the embodiment of the invention, the discharge time of the negative ion generator can be adjusted according to the operation mode of the air purifying equipment, so that the negative ion generation rate can be adjusted in a stepless manner, and the negative ion concentration can be accurately adjusted, namely, the negative ion generator can be controlled to be accurately adjusted to the corresponding negative ion concentration according to the function mode required by a user, the conditions that the adjustment is inaccurate, and the health of the user is harmed due to too high or too low negative ion concentration are avoided, so that the user requirement can be met, and the user experience is improved.
In some embodiments, the adjusting of the discharge time of the ionizer according to the operation mode of the air cleaning apparatus in step S3 includes: according to the operation mode of the air purification equipment, the target output duty ratio of the anion generator corresponding to the operation mode is determined, and the discharge time of the anion generator is adjusted according to the target output duty ratio. Namely, the discharge time of the anion generator is adjusted by determining the target output duty ratio of the anion generator, so that the stepless adjustment of the anion generation rate can be realized.
Specifically, as shown in fig. 2, it is a schematic diagram of a relevant waveform in the process of adjusting the negative ion concentration according to an embodiment of the present invention. For example, as shown in fig. 2, the on-off time of the switching tube of the anion generator is controlled by controlling the target output duty ratio, so that the discharge time of the anion generator is adjusted, and the precise adjustment of the anion concentration is realized.
It can be understood that the target output duty cycles of the corresponding anion generators in different operation modes are different, and the actual output duty cycles of the anion generators can be adjusted by determining the target output duty cycles in different operation modes, so as to adjust the on-off time of the switching tubes of the anion generators, and adjust the discharge time of the anion generators. For example, when the air purification device is in a refreshing mode, the target output duty ratio of the anion generator corresponding to the refreshing mode is determined, for example, the target output duty ratio is recorded as D, the discharge time of the anion generator is adjusted according to the target output duty ratio D, and particularly, the actual output duty ratio is adjusted according to the target output duty ratio D, so that the target output duty ratio D is reached, the on-off time of the switching tube is adjusted, the discharge time of the anion generator is adjusted, the anion generation rate of the anion generator is adjusted in a stepless mode, and the anion concentration is accurately adjusted. In the process, the discharge time is adjusted by adjusting the target output duty ratio D, so that the concentration of the negative ions is accurately adjusted, the concentration of the negative ions meets the corresponding concentration requirement of the negative ions in a refreshing mode, the user requirement is met, and the user experience is improved. That is, by determining the target output duty ratio D of the ionizer, the adjustment of the discharge time of the ionizer is realized, thereby realizing the adjustment of the anion concentration. The process of adjusting the concentration of negative ions in other operation modes, such as the purification mode, is similar to the process of adjusting the concentration of negative ions in the refresh mode, and is not repeated here.
In one embodiment of the present invention, the range of the target output duty ratio is configured to [0.2,1], for example, thereby ensuring that the ionizer is normally discharged.
In some embodiments, as shown in fig. 3, a schematic diagram of a circuit structure of the ionizer according to one embodiment of the present invention is shown. Specifically, as shown in fig. 3, after the anion generator is started, the target output duty ratios D corresponding to different operation modes are different, the target output duty ratio D corresponding to the current operation mode is determined, the target output duty ratio D is input through an MCU IO port and is connected to the input of the and gate B through a fast optical coupler, the square wave of the oscillation circuit is connected to the input of the and gate a, and the and gate controls the discharge time of the anion generator through a level conversion driving switching tube, so as to realize the accurate adjustment of the anion concentration.
In some embodiments, as shown in fig. 3, the frequency corresponding to the target output duty ratio D is a preset frequency, and the preset frequency is determined according to the switching tube frequency of the ionizer. Specifically, the preset frequency is, for example, denoted as f _ pwm, the frequency of the switching tube is, for example, denoted as f _ switch, and the value of f _ switch is, for example, 20kHz to 800 kHz. When the negative ion generator works, the boosting establishment and the voltage reduction discharging process need about 5 switching cycles, so that the preset frequency f _ pwm is far less than the frequency f _ switch of the switching tube, and the normal work of the negative ion generator is ensured. In a specific example, f _ pwm < f _ switch/20 is set.
In some embodiments, the operation modes of the air purifying apparatus include at least a refresh mode and a purification mode, wherein a target output duty ratio of the ionizer corresponding to the refresh mode is, for example, 0.4; the target output duty ratio corresponding to the purge mode ionizer is, for example, 0.8. In a specific embodiment, the target output duty ratios of the corresponding anion generators in different operation modes can be calibrated in advance through empirical values.
For example, when the operation mode of the air purification device is determined to be the refresh mode, the corresponding target output duty ratio D in the refresh mode is determined, namely 0.4; or, when the operation mode of the air purification device is determined to be the purification mode, determining the corresponding target output duty ratio D in the purification mode, namely 0.8. The target output duty ratio D corresponding to different operation modes is input through the MCU IO port of the anion generator, the B input of the AND gate is connected through the quick optical coupler, the square wave generated by the oscillating circuit is connected to the A input of the AND gate, the AND gate drives the switch tube through level conversion, the discharge time of the anion generator is adjusted, the accurate adjustment of the anion concentration is realized, thereby the air purification function corresponding to the air purification equipment under various operation modes is realized, the requirements of users on different function modes are met, and the user experience is improved.
The method for adjusting the negative ion concentration according to the embodiment of the present invention is described in detail with reference to fig. 4, which is a flowchart of the method for adjusting the negative ion concentration according to the embodiment of the present invention, as shown in fig. 4.
