Referring to fig. 2, in a first embodiment, the control method of the air conditioner includes the steps of:
step S10, when the sterilization condition is satisfied, starting the sterilization module;
in this embodiment, the air conditioner includes purification wind channel and heat transfer wind channel, be provided with the sterilization module in the purification wind channel, arbitrary mode such as sterilization module accessible ultraviolet sterilization, plasma sterilization realizes the purpose of disinfecting, for example, when the sterilization module is through ultraviolet sterilization, the sterilization module can be the ultraviolet sterilamp, be used for killing microorganism such as bacterial propagule, spore, mycobacteria, coronavirus, fungi, rickettsia and chlamydia, the ultraviolet ray that the ultraviolet sterilamp produced can shine on the filter screen surface of filter screen, be used for getting rid of the bacterium in the air of filter screen surface and flow through the filter screen.
Optionally, a filter screen is arranged in the purification air duct, the filter screen is arranged opposite to the sterilization module, and the filter screen is used for purifying air flowing through the purification air duct. The Filter screen can be a High efficiency air Filter (HEPA) Filter screen to Filter particulate matters in the air and achieve the purpose of purifying the indoor air.
And when the sterilization condition is met, starting the sterilization module to remove bacteria on the surface of the filter screen and in the air flowing through the filter screen by the ultraviolet light generated by the sterilization module. The sterilization condition may be any trigger condition, for example, whether the sterilization condition is satisfied is determined according to the number of bacteria in the indoor air, where the number of bacteria in the indoor air may be determined by the number of bacteria in the air at the air inlet or the air outlet of the purification air duct, or the number of bacteria in the air at other indoor positions. Therefore, the number of bacteria in the air at the air inlet or the air outlet of the purification air duct can be detected in real time, if the detected number of bacteria is larger than the preset number of bacteria, more bacteria in the current indoor air are represented, the bacteria can be removed through the sterilization module, or the time interval between the last operation sterilization module time point and the current time point is detected, if the time interval is larger than the preset time interval, the fact that the bacteria are not sterilized for a long time is represented, the bacteria can be removed through the sterilization module, and therefore the sterilization condition can include at least one of the conditions. In addition, the opening of the sterilization module can also be controlled manually by a user, namely when a sterilization instruction triggered by the user is received, the sterilization condition is judged to be met, and the sterilization module is started.
Optionally, after the sterilization module is started, the state of the fan in the purification air channel can be detected, if the fan in the purification air channel is in a closed state, it indicates that the indoor air is not purified by the filter screen in the purification air channel at present, therefore, the fan in the purification air channel can be opened, so that the indoor air flows through the sterilization module, the sterilization treatment is performed on the indoor air by the sterilization module, and the indoor air can also flow through the filter screen in the purification air channel, thereby realizing the further air purification effect.
Optionally, after the sterilization module is started, if the fan in the purification air duct is in an operating state, it indicates that the indoor air is currently purified through the filter screen in the purification air duct. Generally speaking, the bacterium can be got rid of completely in the effect of sterilization module, need certain time, consequently, if the wind speed in the air purification channel is too big, can make the corresponding sterilization time of bacterium too short, can't reach better bactericidal effect. When the indoor air is purified through the filter screen in the purification air channel, the air speed in the purification air channel is generally larger, and at the moment, the rotating speed of a fan in the purification air channel can be reduced to reduce the air speed in the purification air channel, so that the sterilization effect of the sterilization module is improved. It should be noted that, when the sterilization module is closed, it is not necessary to consider whether the sterilization duration is sufficient, and therefore, the air flow passing through the filter screen can be increased by the higher air speed of the purification fan, so as to accelerate the indoor air purification rate.
Step S20, controlling fans in the purification air duct and the heat exchange air duct to operate;
and step S30, controlling at least one of the transverse air deflector and the longitudinal air deflector of the air outlet of the heat exchange air duct to rotate.
In this embodiment, when disinfecting and purifying the room air, the fan operation in control purification wind channel and the heat transfer wind channel for the filter screen in the purification wind channel is constantly flowed through to the room air, realizes air-purifying's purpose, and, fan through the heat transfer wind channel constantly toward indoor air supply, makes the room air flow accelerate, avoids the condition of the filter screen in the purification wind channel that can't flow through all the time of indoor part air, has improved the effect that the air conditioner purifies the room air.
The air outlet of the air conditioner heat exchange air duct is provided with at least one of a transverse air deflector and a longitudinal air deflector. When indoor air is disinfected and purified, at least one of the transverse air guide plate and the longitudinal air guide plate is controlled to rotate, so that the air outlet direction of the heat exchange air channel is adjusted by adjusting the deflection angle of the transverse air guide plate or the longitudinal air guide plate.
Optionally, there are various ways of controlling the rotation of at least one of the transverse air guiding plate and the longitudinal air guiding plate, so as to achieve the purpose of accelerating the indoor air flow. For example, the horizontal air deflector is controlled to rotate only, the longitudinal air deflector is controlled to rotate only, the horizontal air deflector and the longitudinal air deflector are controlled to rotate simultaneously, the horizontal air deflector and the longitudinal air deflector are controlled to rotate alternately, at least one of the horizontal air deflector and the longitudinal air deflector is controlled to rotate continuously for a preset time or for a preset number of times and then to be stationary, and at least one of the horizontal air deflector and the longitudinal air deflector is controlled to rotate to a preset position or a preset angle and then to be stationary.
Optionally, detect indoor particulate matter concentration, when indoor particulate matter concentration is greater than preset threshold value, open the fan in the purification wind channel to through the indoor air of the filter screen purification flow through of the filter screen in the purification wind channel. And after the fan in the purification air duct is started, at least one of the transverse air guide plate and the longitudinal air guide plate of the air outlet of the heat exchange air duct can be controlled to rotate, so that indoor air flow is accelerated, and the air purification effect of the filter screen is improved.
Optionally, when the sterilization module is turned off and operated, the control modes of the transverse air deflector and the longitudinal air deflector can be different, so as to achieve different air purification effects. For example, when the sterilization module is closed, it means that only the fan for purifying the air duct is turned on, the filter screen in the air duct is used for purifying the indoor air, and the main objects for purification are particles such as dust in the air, so that the transverse air deflector can be controlled to rotate within a preset angle, the area corresponding to the preset angle is located on the upper portion of the horizontal plane where the transverse air deflector is located, that is, the air conditioner is controlled to blow air to the upper indoor position and not to blow air to the lower indoor position, so as to prevent the particles such as dust falling from the ground to be blown into the air again when the air is blown to the lower indoor position, thereby increasing the reverse effect of the particles in the air, and the particles such as dust falling into the air at the lower indoor position can be regarded as about to fall to the ground, so that the particles. When the sterilization module operates, the transverse air guide plate is controlled to rotate back and forth between the maximum rotation angle and the minimum rotation angle, namely the air conditioner is controlled to blow air to the indoor upper position and the indoor lower position in sequence, the air conditioner is larger in air supply radiation range, so that the flow of indoor air is more uniform, bacteria in the air at the indoor lower position and the indoor upper position are removed simultaneously, and the number of the bacteria in the indoor air is guaranteed not to exceed the standard. It should be noted that, when removing bacteria in the air, the problem of re-blowing up particles such as dust that have fallen near the floor surface can be ignored, so as to achieve a good air sterilization effect.
In the technical scheme disclosed in the embodiment, the indoor air flow is accelerated through the rotation of at least one of the transverse air guide plate and the longitudinal air guide plate, so that the indoor air is more uniform, and the sterilization effect of the sterilization module is improved.
In a second embodiment, as shown in fig. 3, on the basis of the above embodiment shown in fig. 2, after step S10, the method for controlling an air conditioner further includes:
and step S01, when the operation time of the sterilization module reaches the preset operation time, executing the step of controlling the operation of the fans in the purification air duct and the heat exchange air duct.
In this embodiment, after the sterilization module is started, the current operation time of the sterilization module is detected, when the current operation time reaches the preset operation time, the bacteria inside the air conditioner are represented to be removed, and the step of controlling the operation of the fans in the purification air duct and the heat exchange air duct is executed. The filter screen of the air conditioner is firstly sterilized through the sterilization module, after the sterilization process of the filter screen is finished, the air is continuously circulated indoors and inside the air conditioner through the operation of the fan, so that the air purification is realized, the indoor air circulation is carried out when more bacteria are left on the filter screen, and the problem that the bacteria in the air conditioner are diffused into the indoor air is caused.
In the technical scheme disclosed in this embodiment, reach when presetting the operation when the module that disinfects during the operation, the step of the fan operation in control purification wind channel and the heat transfer wind channel is carried out, through carrying out indoor air purification after the completion of disinfecting inside the air conditioner, has avoided the diffusion of the inside bacterium of air conditioner to improve the bactericidal effect of air conditioner.
In the third embodiment, as shown in fig. 4, after step S30, on the basis of the embodiment shown in any one of fig. 2 to fig. 3, the method further includes:
step S40, detecting the bacterial number of the indoor air in real time;
and step S50, when the bacteria data is less than or equal to the preset bacteria number, closing the sterilization module and stopping rotating the transverse air deflector and the longitudinal air deflector.
In this embodiment, the bacterium quantity of real-time detection room air, when the bacterium quantity is greater than preset bacterium quantity, the present bacterium in the room air of sign is more, need disinfect, when bacterium quantity is less than or equal to preset bacterium quantity, the present bacterium in the room air of sign is less, can not disinfect or stop disinfecting. Of course, the number of bacteria at other positions of the air conditioner may be detected, and the sterilization may be stopped when the number of bacteria is less than or equal to the preset number of bacteria, or the average value of the numbers of bacteria at a plurality of positions of the air conditioner may be used as the basis for determining whether to stop the sterilization.
Because partial indoor air after being sterilized by the sterilization module may be gathered near the air outlet of the purification air duct, and the partial indoor air which is not sterilized is far away from the air inlet of the purification air duct, and sterilization cannot be performed, the number of bacteria in the air at the air inlet or the air outlet of the purification air duct, which are detected, is inaccurate due to the non-uniformity of the indoor air. After the problem of uneven indoor air is solved by controlling at least one of the transverse air deflector and the longitudinal air deflector to accelerate the indoor air flow, if the number of bacteria in the indoor air is detected to be less than or equal to the preset number of bacteria, the current number of bacteria in the indoor air is represented to be less, and therefore the steps of turning off the air conditioner, turning off the sterilization module and stopping rotating at least one of the transverse air deflector and the longitudinal air deflector can be executed.
Optionally, after the sterilization module is started, determining an interval corresponding to the number of bacteria according to the number of bacteria in the indoor air detected in real time, and controlling the sterilization module to operate according to the power corresponding to the interval. For example, when the number of bacteria is 2500 colonies/m3The power of the sterilization module is adjusted to 20 watts, and the bacterial count is 3100 colony counts/m3The power of the sterilization module is adjusted to 30 watts. The power of the sterilization module is adjusted to change the ultraviolet intensity generated by the sterilization module so as to realize different ultraviolet sterilization purposes.
In the technical scheme disclosed in this embodiment, when the number of bacteria in the air at the air inlet or the air outlet of the purification air duct is less than or equal to the preset number of bacteria, the sterilization module is closed and the transverse air deflector and the longitudinal air deflector stop rotating, so that the indoor air sterilization process is finished, and unnecessary energy consumption of the air conditioner is saved.
In the fourth embodiment, as shown in fig. 5, on the basis of the embodiment shown in any one of fig. 2 to 4, step S30 includes:
and step S31, controlling at least one of the transverse air deflector and the longitudinal air deflector to continuously rotate for a preset number of times or for a first preset duration.
In this embodiment, the step of controlling at least one of the transverse air guiding plate and the longitudinal air guiding plate to rotate may include controlling at least one of the transverse air guiding plate and the longitudinal air guiding plate to rotate continuously until the indoor air sterilization process is finished, or may include controlling at least one of the transverse air guiding plate and the longitudinal air guiding plate to rotate continuously for a preset number of times or for a first preset time period and then to be stationary. In the process of controlling at least one of the transverse air deflector and the longitudinal air deflector to rotate continuously for a preset number of times or for a first preset time and then to be static, indoor air flow is accelerated through continuous rotation of at least one of the transverse air deflector and the longitudinal air deflector, and air outlet with the maximum efficiency of the air conditioner is ensured through controlling at least one of the transverse air deflector and the longitudinal air deflector to be static.
Because the transverse air deflector or the longitudinal air deflector rotates back and forth within a certain angle range when rotating, the transverse air deflector or the longitudinal air deflector can be counted once when rotating back and forth, and the continuous rotation for the preset times is the back and forth rotation for the preset times within the first angle range.
Optionally, after the step of controlling at least one of the transverse air deflector and the longitudinal air deflector to rotate continuously for the preset number of times or for the first preset time and then to be stationary, the step of controlling at least one of the transverse air deflector and the longitudinal air deflector to rotate continuously for the preset number of times or for the first preset time may be performed again, that is, the step of controlling at least one of the transverse air deflector and the longitudinal air deflector to rotate continuously for the preset number of times or for the first preset time may be performed every second preset time. Through the alternate execution of continuous rotation and stillness of at least one of the transverse air deflector and the longitudinal air deflector, the indoor air can be ensured to be in a flowing state all the time, and the air outlet of the air conditioner with the maximum efficiency can be ensured, so that the disinfection effect of the air conditioner is better.
It should be noted that when at least one of the transverse air guiding plate and the longitudinal air guiding plate needs to be controlled to be stationary, the transverse air guiding plate and the longitudinal air guiding plate can be controlled to be stationary at a position corresponding to the maximum rotation angle, so as to ensure that the air supply of the air conditioner accelerates the indoor air flow to the maximum extent.
In the technical scheme disclosed in this embodiment, at least one of the transverse air deflectors and the longitudinal air deflector is controlled to continuously rotate for a preset number of times or for a first preset time, and through the switching between rotation and static state, the flow of indoor air and the quick air outlet of the air conditioner are ensured at the same time, so that the air purification effect of the air conditioner is improved.
