Background
At present, a common filtering mode of the air purifier is to adopt a composite filter screen for filtering, and as the service time of a user increases, the filter screen in the air purifier becomes dirty more and less, and the purifying effect is also bad. In order to prolong the service life of the filter screen, a high-voltage module can be arranged in the air purifier, and the high-voltage electrostatic field generated by the high-voltage module is utilized to adsorb and remove dust.
However, in the operation process of the high-pressure module, oxygen molecules in the air around the metal filter screen can be ionized and decomposed into oxygen atoms, and in the process, the oxygen atoms collide with other oxygen molecules to form ozone molecules. When the ozone concentration is more than 100ppb, the human respiratory tract is easily irritated and inflamed; when the concentration reaches 50000ppb, there is a life hazard. Thus, when a high-pressure module is added to the air purifier, it is necessary to control the concentration of ozone generated by the air purifier.

Detailed Description
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is apparent that the described embodiments are some embodiments of the present invention, but not all embodiments of the present invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
According to an embodiment of the present invention, there is provided a control method embodiment of an air cleaner, it being noted that the steps shown in the flowcharts of the drawings may be performed in a computer system such as a set of computer executable instructions, and that although a logical order is shown in the flowcharts, in some cases the steps shown or described may be performed in an order different from that herein.
In the embodiment, a control method of an air purifier is provided, which can be used for computer equipment. In this embodiment, the air purifier includes a high-voltage module (may also be referred to as a voltage doubler module) and an ultraviolet lamp (may also be referred to as an ultraviolet lamp). When the high-pressure module works, oxygen molecules in the air around the filter screen can be ionized and decomposed into oxygen atoms, and in the process, the oxygen atoms collide with other oxygen molecules to form ozone molecules. In order to control the concentration of ozone generated by the air purifier, an ultraviolet lamp is arranged in the air purifier, the ultraviolet lamp can emit ultraviolet rays, the ozone is extremely unstable, and the ozone is decomposed into dissolved oxygen after absorbing the ultraviolet rays with the wavelength of 254 nm; the energy provided by the ultraviolet rays can break chemical bonds in the ozone to generate oxygen; that is, ozone becomes oxygen after absorbing ultraviolet rays. Because the cost of the ultraviolet lamp is lower, the embodiment of the invention utilizes the ultraviolet lamp to decompose ozone, so that the cost of decomposing ozone can be reduced; in addition, the ultraviolet lamp can decompose ozone and kill microbes such as bacteria and viruses in the machine rapidly and effectively, and the microbes generate photochemical reaction under the irradiation of ultraviolet rays, so that the nucleic acid of the microbes is destroyed and deactivated.
Fig. 1 is a flowchart of an air cleaner control method according to an embodiment of the present invention, as shown in fig. 1, the flowchart including the steps of:
step S101: after the high-voltage module and the ultraviolet lamp are started, the first ozone concentration at the air outlet of the air purifier is obtained.
Specifically, a first ozone sensor can be arranged at the air outlet of the air purifier, and the first ozone concentration at the air outlet of the air purifier is obtained through the first ozone sensor.
Step S102: and adjusting the brightness of the ultraviolet lamp according to the first ozone concentration at the air outlet.
Specifically, when the ultraviolet lamp is controlled using PWM, the brightness of the ultraviolet lamp can be controlled by adjusting the duty ratio of the PWM wave.
This is because, after the high voltage module and the ultraviolet lamp are started, the first ozone concentration at the air outlet can represent the matching degree of the ozone generating speed of the high voltage module in the air purifier and the ozone decomposing speed of the ultraviolet lamp, and when the voltage and the power of the high voltage electric field of the high voltage module are unchanged, the ozone decomposing speed is determined by the brightness of the ultraviolet lamp. The greater the intensity of the ultraviolet lamp, the faster the ozone decomposition rate. Therefore, the brightness of the ultraviolet lamp can be adjusted according to the first ozone concentration at the air outlet.
According to the control method for the air purifier provided by the embodiment of the invention, after the high-voltage module and the ultraviolet lamp are started, the first ozone concentration at the air outlet of the air purifier is obtained, and the brightness of the ultraviolet lamp is regulated according to the first ozone concentration at the air outlet, so that the ozone generating speed of the high-voltage module and the ozone decomposing speed of the ultraviolet lamp are balanced, the first ozone concentration at the air outlet of the air purifier meets the standard requirement (for example, is less than 50 ppb), and adverse effects are not generated on users.
It should be noted that, a fan is further disposed inside the air purifier, and in the related art, the speed of ozone generated by the high-voltage module and the speed of ozone decomposed by the ultraviolet lamp are balanced by adjusting the rotation speed of the fan and changing the stay time of ozone inside the air purifier. However, in order to control the rotation speed of the fan, a direct current motor is required, and the price of the direct current motor is high. The embodiment of the invention only needs to improve the program in the computer equipment, controls the brightness of the ultraviolet lamp by controlling the PWM wave output and adjusting the PWM wave duty ratio, thereby controlling the photolysis rate of the ultraviolet lamp and controlling the concentration of ozone in the interior. The hardware of the air purifier is not required to be improved, and the production cost is reduced.
In the embodiment, a control method of an air purifier is provided, which can be used for computer equipment. Fig. 2 is a flowchart of another air cleaner control method according to an embodiment of the present invention, as shown in fig. 2, the flowchart including the steps of:
step S201: after the high-voltage module and the ultraviolet lamp are started, the first ozone concentration at the air outlet of the air purifier is obtained.
Specifically, a first ozone sensor can be arranged at the air outlet of the air purifier, and the first ozone concentration at the air outlet of the air purifier is obtained through the first ozone sensor.
Step S202: and adjusting the brightness of the ultraviolet lamp according to the first ozone concentration at the air outlet.
Specifically, step S202 includes:
s2021: and when the first ozone concentration at the air outlet is smaller than a preset first threshold value, reducing the brightness of the ultraviolet lamp.
Specifically, when the ultraviolet lamp is controlled using PWM, the brightness of the ultraviolet lamp can be reduced by reducing the duty ratio of the PWM wave.
For example, y=k (r-a) +z, r < a, where Y represents the brightness of the current uv lamp, K represents a scaling factor, r represents a first ozone concentration at the air outlet, and a represents a first threshold; z represents the initial brightness of the UV lamp.
S2022: when the first ozone concentration at the air outlet is larger than a preset second threshold value, the brightness of the ultraviolet lamp is improved.
Specifically, when the ultraviolet lamp is controlled using PWM, the brightness of the ultraviolet lamp can be improved by increasing the duty ratio of the PWM wave.
For example, y=k (r-b) +z, r < a, where Y represents the brightness of the current uv lamp, K represents a scaling factor, r represents a first ozone concentration at the air outlet, and b represents the second threshold; z represents the initial brightness of the UV lamp.
S2022: when the first ozone concentration at the air outlet is larger than or equal to a first threshold value and smaller than or equal to a second threshold value, the brightness of the ultraviolet lamp is kept unchanged.
For example, when the first threshold is denoted by a and the second threshold is denoted by b, the second threshold may be denoted by one concentration range [ a, b ] when being equal to or greater than the first threshold and equal to or less than the second threshold.
According to the control method for the air purifier, after the high-voltage module and the ultraviolet lamp are started, the first ozone concentration at the air outlet of the air purifier is obtained, and the brightness of the ultraviolet lamp is adjusted according to the first ozone concentration at the air outlet, so that the ozone generating speed of the high-voltage module and the ozone decomposing speed of the ultraviolet lamp are balanced, the first ozone concentration at the air outlet of the air purifier meets the standard requirement, and adverse effects on users are avoided.
In the embodiment, a control method of an air purifier is provided, which can be used for computer equipment. Fig. 3 is a flowchart of still another air cleaner control method according to an embodiment of the present invention, as shown in fig. 3, the flowchart including the steps of:
step S301: and after the high-voltage module and the ultraviolet lamp are started, acquiring the second ozone concentration at the air inlet of the air purifier and the third ozone concentration in the air purifier.
Specifically, a second ozone sensor can be arranged at the air inlet of the air purifier, and the second ozone concentration at the air inlet of the air purifier is detected through the second ozone sensor. A third ozone sensor may be provided inside the air cleaner, and a third ozone concentration inside the air cleaner may be detected by the third ozone sensor. For example, a third ozone sensor may be disposed between the high voltage module and the ultraviolet lamp.
Step S302: and determining whether the high-voltage module works normally or not according to the second ozone concentration at the air inlet and the third ozone concentration inside.
Specifically, step S302 includes:
step S3021: and when the concentration of the second ozone at the air inlet is smaller than the concentration of the third ozone in the air inlet, judging that the high-voltage module works normally.
This is because, when the high-voltage module is operating normally, ozone is generated inside the air cleaner, and thus the second ozone concentration at the air intake of the air cleaner is smaller than the third ozone concentration inside the air cleaner.
Step S3022: when the second ozone concentration at the air inlet is equal to or more than the third ozone concentration in the air inlet within the preset first time period, judging that the high-voltage module fails, and sending out a first prompt message of the high-voltage module failure.
This is because, when the second ozone concentration at the air inlet is equal to or greater than the third ozone concentration inside the air purifier within the preset first time period, it is indicated that no ozone is generated inside the air purifier, and the high-voltage module fails. Therefore, accidental factors can be eliminated, and whether the high-voltage module fails or not can be accurately determined.
Step S303: when the high-voltage module works normally, the first ozone concentration at the air outlet of the air purifier is obtained.
Step S304: and determining whether the ultraviolet lamp works normally or not according to the first ozone concentration at the air outlet and the third ozone concentration inside.
Specifically, step S304 includes:
step S3041: when the first ozone concentration at the air outlet is smaller than the third ozone concentration inside, whether the ultraviolet lamp works normally or not is judged.
This is because when the ultraviolet lamp is normally operated, ozone generated inside the air cleaner is decomposed, and thus the first ozone concentration at the air outlet is smaller than the third ozone concentration inside.
Step S3042: when the first ozone concentration at the air outlet is equal to or more than the third ozone concentration in the air outlet within the preset second time period, the ultraviolet lamp is judged to be in fault, and a second prompt message of the fault of the ultraviolet lamp is sent out.
This is because, when the first ozone concentration at the air outlet is equal to or greater than the third ozone concentration inside within the preset second period of time, it is indicated that the ultraviolet lamp does not decompose ozone, and the ultraviolet lamp fails.
Step S305: and adjusting the brightness of the ultraviolet lamp according to the first ozone concentration at the air outlet.
According to the control method of the air purifier, the speed of ozone generated by the high-voltage module and the speed of ozone decomposed by the ultraviolet lamp can be balanced by adjusting the brightness of the ultraviolet lamp, so that the first ozone concentration at the air outlet of the air purifier meets the standard requirement and does not adversely affect a user; but also to eliminate the failure of the high voltage module and/or the ultraviolet lamp.
For a detailed description of the control method of the air purifier, a specific example is given. As shown in fig. 4, the control method of the air purifier according to the embodiment of the invention includes the following steps:
1. when the air purifier is started, the first ozone sensor, the second ozone sensor and the third ozone sensor can detect the ozone concentration in real time and return the numerical value to the system.
2. Acquiring a second ozone concentration r1 at an air inlet of an air purifier and a third ozone concentration r2 in the air purifier;
3. when the second ozone concentration r1 of the air inlet is larger than or equal to the third ozone concentration r2 of the inside and the air purifier runs for a certain period of time, the second ozone concentration r1 and the third ozone concentration r2 are not changed, the fact that ozone is not generated in the air purification can be indicated, the high-voltage module fails, and the system can send a failure reminding user.
4. When the second ozone concentration r1 of the air inlet is larger than 50ppb, the air purifier is indicated to be in a room with too high ozone concentration, and the system can give an alarm to prompt the user that the current ozone concentration is in a range harmful to human bodies.
5. Only when the second ozone concentration r1 of the air inlet is smaller than the third ozone concentration r2 of the air inlet, the high-pressure module inside the air purifier is ionized to generate ozone. And then collecting the values of the first ozone concentration r3 and the third ozone concentration r2 in the air outlet, if the value of the first ozone concentration r3 in the air outlet is longer than the value of the third ozone concentration r2 in the air outlet (namely, the operation time length in the figure 4 is longer than the preset time length T), proving that the ultraviolet lamp has a fault and does not play a role in decomposing ozone, and the system reports the fault of the ultraviolet lamp.
6. Only if the first ozone concentration r3 at the air outlet is smaller than the third ozone concentration r2 inside, the inside of the air purifier is considered to continuously generate ozone. Therefore, an ultraviolet lamp is required to decompose ozone, and at the same time, the brightness of the ultraviolet lamp is required to be adjusted so that the ozone generation speed and the ozone decomposition speed inside the air purifier are balanced.
7. When the first ozone concentration r3 at the air outlet is smaller than the preset ozone concentration, the concentration value is small, the system can reduce the duty ratio of PWM waves output by the inside, the power and the brightness of the ultraviolet lamp are reduced, the decomposition rate of ozone is reduced, and the concentration is gradually increased to the preset value.
8. When the first ozone concentration r3 of the air outlet is just within the preset concentration range [ a, b ] (namely a < r3 < b), the decomposition and generation of ozone molecules in the air outlet are at an equilibrium value, and the inside is not adjusted at any time, so that the current equilibrium value is maintained. The duty cycle is not adjusted according to the concentration value until the concentration changes again.
9. When the first ozone concentration r3 of the air outlet is larger than the preset ozone concentration (i.e. r3 > b), the ozone concentration exceeds the preset range, the system needs to increase the duty ratio of the output PWM wave, increase the brightness of the ultraviolet lamp and increase the ozone photolysis rate, so that the ozone concentration is reduced to the preset range [ a, b ].
10. When the first ozone concentration r3 of the air outlet is smaller than the preset ozone concentration (i.e. r3 < a), the ozone concentration is lower than the preset concentration range, the system needs to reduce the output PWM wave duty ratio, the brightness of the ultraviolet lamp is reduced, and the ozone photolysis rate is reduced.
In summary, the control method of the air purifier provided by the embodiment of the invention detects the air inlet, the air outlet and the internal ozone concentration through the ozone sensor, and controls the brightness of the ultraviolet lamp by controlling the output of the internal PWM wave and adjusting the duty ratio of the PWM wave, thereby controlling the ultraviolet photolysis rate and the internal ozone concentration, and further ensuring that the ozone concentration generated by the air purifier is controllable and harmless to human bodies.
