Description

Control method and control device of air purifier and air purifier
Technical Field
The invention relates to the technical field of household appliances, in particular to a control method and a control device of an air purifier and the air purifier.
Background
Along with the improvement of the living standard of people, a plurality of intelligent electric appliances enter the life of people, and the air purifier is a daily use of people. The existing purifier can not kill viruses, and possibly causes secondary pollution to air in the process of circularly purifying the air, thereby bringing adverse effects to the health of users and living environment.
In the prior art, most air purifiers use heat sterilization to kill viruses in the air passing through the filter screen, which can be sterilized at 50 to 70 ℃, because the viruses can be inactivated by high temperature. When the air passes through the filter screen, the filter screen is heated at high temperature, so that viruses adsorbed on the filter screen are killed. At present, when the temperature of the filter screen is controlled, the temperature near the filter screen is generally collected through a temperature sensing bulb, when the temperature reaches a preset value, the air exhaust amount of a fan is increased, and the heating power is reduced, so that the temperature rising rate is reduced, and the thermal balance state is reached.
However, air purifiers cannot be compatible at the same time with different ambient temperatures. For example, when the ambient temperature is 40 ℃, the temperature is only 10 ℃ away from the sterilization temperature (the sterilization temperature is 50 ℃), the temperature rises too fast, the time is required for the temperature detection device to detect the temperature, and then the rotating speed and the heating power of the fan are adjusted, so that the temperature also continues to rise in the period of time. Because the temperature resistance of the filter screen is generally between 70 and 80 ℃, the filter screen is easy to age and lose efficacy after exceeding 70 ℃. If the ambient temperature is 0 c and the fan speed is still according to the fan speed and heating power set when the ambient temperature is 40 c, then it takes a long time to rise from 0 to 50 c. And under the condition that ambient temperature is low, the temperature rises more slowly, makes air purifier can not reach preset temperature value for a long time, and the time waste brings relatively poor life experience for the user.

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.
In the prior art, most air purifiers use heat sterilization to kill viruses in the air passing through the filter screen, which can be sterilized at 50 to 70 ℃, because the viruses can be inactivated by high temperature. When the air passes through the filter screen, the filter screen is heated at high temperature, so that viruses adsorbed on the filter screen are killed. At present, when the temperature of the filter screen is controlled, the temperature near the filter screen is generally collected through a temperature sensing bulb, when the temperature reaches a preset value, the air exhaust amount of a fan is increased, and the heating power is reduced, so that the temperature rising rate is reduced, and the thermal balance state is reached. However, the temperature of the screen is typically in excess of 70 ℃ due to the rapid rise in screen temperature and insensitive temperature sensed by the bulb. After the temperature of the filter screen exceeds 70 ℃, the filter screen is easy to age and lose efficacy, the frequency of replacing the filter screen by a user can be increased, and poor life experience is brought to the user.
The control method and the control device of the air purifier and the air purifier are used for solving the problems that in the prior art, when the air purifier works, the temperature of a filter screen is easy to exceed 70 ℃, the frequency of replacing the filter screen by a user is increased, and the life experience of the user is poor.
Example 1
As shown in fig. 1 and 4, an embodiment of the present invention provides a control method of an air purifier, including:
s1, obtaining an ambient temperature, and determining a temperature rise curve corresponding to the ambient temperature;
when the air purifier starts to work, the ambient temperature of the position of the air purifier is firstly obtained. Because the temperature rising curves corresponding to different ambient temperatures are different, the air purifier can be ensured to adjust the self heating power and the fan rotating speed in time under different ambient temperatures.
For example, when the ambient temperature is 40 ℃, the preset temperature rising curve is relatively gentle. The filter screen can be stably raised to the sterilization temperature range of 50-70 ℃ when being heated. When the temperature of the filter screen rises to the sterilization temperature interval, the air purifier can control the heating power and the rotating speed of the fan to be unchanged. Thereby ensuring that the screen does not exceed 70 c. The service life of the filter screen is prolonged.
For example, when the ambient temperature is 0 ℃, the gradient of the preset temperature rising curve is large, so that the filter screen can be rapidly raised to a temperature range close to the sterilization temperature when being heated. And then the filter screen is controlled to stably rise to the sterilization temperature range, so that the temperature rise time is shortened, and the service life of the filter screen can be prolonged.
S2, obtaining the current temperature, and determining a standard temperature rising rate corresponding to the current temperature on the temperature rising curve;
after the temperature rise curve is determined, the slope of the temperature rise curve at each point is the corresponding standard temperature rise rate at that temperature. As shown in FIG. 5, the temperature rise curve is shown at 25 ℃ for ambient temperature.
Open heating device, heating device heats air purifier's filter screen, acquires the current temperature around the filter screen. A standard temperature rise rate corresponding to the current temperature is then determined on the temperature rise curve.
S3, acquiring the current heating rate;
the temperature changed in the heating process of the filter screen is collected, so that the current temperature rise rate at the current temperature can be automatically obtained.
Specifically, the method comprises the following steps:
s31, acquiring historical temperature before a preset time period;
the temperature changed in the heating process of the filter screen is collected, a certain historical temperature before a preset time period is determined by taking the preset time period as a time variation.
And S32, determining the current heating rate according to the historical temperature, the current temperature and the preset time period. The formula is as follows:
Figure GDA0003172752050000081
wherein K is the current temperature rise rate, TDIs the current temperature, TLThe historical temperature, Δ t, is a preset time period.
So that the current temperature-rise rate corresponding to the current temperature can be calculated.
Of course, in order to improve the accuracy of the current temperature-increasing rate corresponding to the current temperature, the time length of the preset time period may be reduced, and may be set to 0.1S or 0.5S, for example. The time length of the preset time period can be changed by a person skilled in the art according to actual situations, and this embodiment is merely an example, and is not limited, and the same technical effect can be achieved.
And S4, adjusting working parameters of a fan and/or a heating device of the air purifier according to the current heating rate and the standard heating rate.
After the current heating rate is obtained, the current heating rate is compared with the standard heating rate, and then working parameters of a fan and/or a heating device of the air purifier are adjusted.
Specifically, step S3 includes:
s40, judging whether the current heating rate is greater than a standard heating rate or not;
s41, when the current heating rate is smaller than the standard heating rate, reducing the rotating speed of the fan and/or improving the heating power;
s42, when the current heating rate is larger than the standard heating rate, increasing the rotating speed of the fan and/or reducing the heating power;
s43, when the current temperature rising rate is equal to the standard temperature rising rate, keeping the rotating speed of the fan and/or the heating power unchanged.
According to the control method of the air purifier, the heating rates corresponding to different temperature values can be calculated, when the current heating rate is higher than the standard heating rate in unit time, the rotating speed of the fan is increased, the heating power is reduced, and when the current heating rate is lower than the standard heating rate, the rotating speed of the fan is reduced. Therefore, the temperature of the filter screen is balanced, and the problems that the temperature of the filter screen cannot reach 50-70 ℃ of working temperature due to the fact that a temperature detection device is insensitive or is influenced by the ambient temperature, or the temperature of the filter screen exceeds the working temperature, the temperature of the filter screen is too high, and the filter screen is easy to age are solved. The frequency of replacing the filter screen by a user is reduced, and the use experience of the user is improved.
In this embodiment, to further improve the accuracy of the control of the temperature rise rate, the fan speed and the heating power may be adjusted at regular intervals. The adjusted interval time can be changed by those skilled in the art according to actual conditions, for example, when the current temperature rising rate and the standard temperature rising rate are greatly different, the interval time can be reduced, and when the difference is smaller, the interval time can be increased. The adjustment range can be changed by a person skilled in the art according to actual conditions, for example, when the current temperature-rising rate and the standard temperature-rising rate have a large difference, the adjustment range of the fan speed and the heating power can be increased, and when the difference is small, the adjustment range of the fan speed and the heating power can be reduced.
Specifically, the method can comprise the following steps:
and S5, calculating a difference value between the current temperature rising rate and the standard temperature rising rate, and determining the rotating speed of the fan and/or the heating power of the heating device according to the difference value.
The preset standard temperature increasing rate is K0, the actually detected current temperature increasing rate is K, and in this embodiment, the current temperature increasing rate K may be read once every 5 seconds for adjustment.
When the standard temperature rise rate K0 is greater than 0.5, the specific conditions for the adjustment are as follows:
Figure GDA0003172752050000101
when the standard temperature rise rate K0 is less than 0.5, the specific conditions for the adjustment are as follows:
Figure GDA0003172752050000111
as shown in the above table, when the standard temperature-raising rate K0 is greater than 0.5, it means that the ambient temperature is far from the sterilization temperature, and a rapid temperature-raising is required. For example, if K0/K is larger than or equal to 4, the rotating speed of the fan is reduced by 200r/min, and the heating power is increased by 150W.
When the standard temperature rise rate K0 is less than 0.5, the environment temperature is close to the sterilization temperature, the temperature needs to be raised slowly, and only the rotating speed of the fan is changed. For example, if K0/K is greater than or equal to 2, the fan speed is reduced by 150r/min, which will not be described in detail.
Example 2
As shown in fig. 2, an embodiment of the present invention further provides a control device of an air purifier, including:
a determining module 100, configured to obtain a current temperature, and determine a standard temperature increase rate corresponding to the current temperature; for details, reference may be made to the related description of step S1 in the above method embodiment, and details are not repeated herein;
an obtaining module 200, configured to obtain a current temperature rise rate; for details, reference may be made to the related description of step S2 in the above method embodiment, and details are not repeated herein;
for details of adjusting the operating parameters of the fan and/or the heating device of the air purifier according to the current temperature-rising rate and the standard temperature-rising rate, reference may be made to the related description of step S3 in the above method embodiment, and details are not described here again.
Has the advantages that: the heating rates corresponding to different temperature values can be calculated, when the current heating rate in unit time is higher than the standard heating rate, the rotating speed of the fan is increased, the heating power is reduced, and when the current heating rate is lower than the standard heating rate, the rotating speed of the fan is reduced. Therefore, the temperature of the filter screen is balanced, and the problems that the temperature of the filter screen cannot reach 50-70 ℃ of working temperature due to the fact that a temperature detection device is insensitive or is influenced by the ambient temperature, or the temperature of the filter screen exceeds the working temperature, the temperature of the filter screen is too high, and the filter screen is easy to age are solved. The frequency of replacing the filter screen by a user is reduced, and the use experience of the user is improved.
