In the description of the present invention, "a plurality" means two or more, and "several" means one or more.
A control method of an air conditioner according to an embodiment of the present invention is described below with reference to the accompanying drawings.
As shown in fig. 1, a control method of an air conditioner according to an embodiment of the present invention includes:
acquiring the operating power P of the sterilizing device and the area S of a room where the air conditioner is located;
calculating air supply times Y according to the operating power P and the area S of the room;
and controlling the sterilization device to operate to start a sterilization mode, and supplying air according to the air supply times Y in the sterilization mode.
The room area S can be detected by a room area detection device disposed on the air conditioner, or can be input by a user, for example, by a remote controller, an application program (APP), or voice. And, the operation power P may be not less than 30W to 40W.
For example, each air supply is an ultra-long distance air supply. The ultra-long distance air supply means that the rotating speed of a fan of the air conditioner is the maximum rotating speed, and the angle of an air plate and an air pendulum 300 (shown in fig. 2) positioned at the air outlet of the air conditioner needs to be adjusted so as to enable the air outlet distance of the air conditioner to be the longest.
According to the control method of the air conditioner, the air supply times Y are calculated through the operation power P and the area S of the room, air is supplied according to the air supply times Y in the current sterilization mode, so that the air circulation rate in the room can be increased while the sterilization device is operated, the sterilization effect of the sterilization device is in inverse proportion to the position of the sterilization device, namely the sterilization effect is worse as the sterilization device is farther away from the sterilization device, the air circulation rate is increased, and the sterilization effect on the whole room can be increased. In addition, because the air supply of the air conditioner is interrupted in the sterilization mode, the sterilization device can fully sterilize the air at each air supply interval, the sterilization effect is ensured, and the safety of the living environment is improved.
In addition, the air supply times Y are calculated according to the running power P and the area S of the room, so that air circulation can be increased and the sterilization effect can be increased in the sterilization mode by supplying air according to the air supply times Y, and the air supply times are reasonably set while the sterilization effect is ensured, so that the energy consumption is reduced.
Therefore, the control method of the air conditioner provided by the embodiment of the invention can give consideration to both the sterilization effect and the sterilization range, and improves the safety of the living environment.
According to some embodiments of the present invention, as shown in fig. 1, calculating the air outlet frequency Y according to the operating power P and the room area S includes:
calculating the ratio W of the area S of the room to the operating power P;
multiplying the ratio W by a first correction value N1 to obtain a product N;
judging whether the product N is an integer or not;
if yes, subtracting one from the product N to obtain the air supply times Y;
and if not, rounding the product N downwards to obtain the air supply times Y.
The rounding-down is to be understood as meaning that when the result of the calculation is not an integer, the integer which is smaller than and closest to the result of the calculation is taken. For example, a rounding down of 4.5 results in 4. Also, the first correction value n1 may be 10.
According to some embodiments of the present invention, as shown in fig. 1, when the number of times of blowing Y is calculated to be equal to 0, the sterilization apparatus is turned off after operating for a first preset time T1 to exit the sterilization mode.
Wherein, the air supply time is T, and T can be 1 minute.
In other words, when the number of times of air supply Y is equal to 0, the air conditioner does not need to supply air in the sterilization mode, and the sterilization apparatus can sterilize the entire room. Therefore, the power consumption is reduced and the operation time of the sterilization mode is shortened while the sterilization effect is ensured.
According to some embodiments of the present invention, as shown in fig. 1, when the number of times of air supply Y is calculated to be greater than or equal to 1, the sterilization apparatus operates for the first preset time T1 to start air supply. Like this under the mode of disinfecting, sterilizing equipment just supplies air after having operated a period of time, and sterilizing equipment has disinfected the air of certain limit, and the effect of changing the air can be played in the air supply this moment, is about to blow away the air after disinfecting from the air conditioner, and the air that has not disinfected flows to the air conditioner position. Thus, the sterilization effect and the sterilization range are considered simultaneously.
According to some embodiments of the present invention, as shown in fig. 1, when the number of air blowing times Y is greater than 1, the interval time between two adjacent air blowing times is the first preset time T1.
For example, when P ≧ (n1 × S), the operating time of the sterilization device is T1; when P < (n1 × S), namely S > (P/n1), the air outlet of the air conditioner is needed to change the air distribution state of the room, and further sterilize the air of the whole room. When the value N of (N1 xS)/P is between 1 and 2, the fan of the air conditioner performs air supply for 1 time at an extra-long distance after the sterilizing device operates for every T1 time, the operation time of the fan can be 1 minute, and the working time of the sterilizing device is [ (2 xT 1) +1 minute ]; when the value N of (N1 xS)/P is greater than 2, N is required to be rounded downwards, the fan of the air conditioner performs ultra-long distance air supply for 1 time after the sterilizing device operates for every T1 time, the operation time of the sterilizing device is [ (Y +1) × T1+ Y minutes ] when the fan operates for 1 minute.
So, under the mode of disinfecting, sterilizing equipment just supplies air after first preset time T1 every time, and sterilizing equipment has disinfected the air of certain extent, and the air supply can play the effect of changing the air this moment, is about to blow the air after disinfecting off the air conditioner, and the air that has not disinfected flows to the air conditioner position. Thus, the sterilization effect and the sterilization range are considered simultaneously.
According to some embodiments of the present invention, as shown in fig. 1, a door/window closing prompt and/or a person leaving prompt is issued at a second preset time T2 before the sterilization apparatus is controlled to operate to start the sterilization mode. Wherein, the second preset time T2 may be 1 minute. The natural flow of air in a room can be reduced by closing the door and the window, the time for sterilizing the air by the sterilizing device in the air supply interval is ensured, and the sterilizing effect is further ensured. The safety of personnel in the operation of the sterilization mode is ensured by sending out a prompt for the personnel leaving.
According to some embodiments of the present invention, as shown in fig. 1, after controlling the operation of the sterilization apparatus to start the sterilization mode, it is detected whether a person enters a room in which the air conditioner is located;
if the room has people entering for a third preset time T3, sending a prompt for people to evacuate;
if the room has people entering for a fourth preset time T4, turning off the sterilization device to exit the sterilization mode;
wherein the fourth preset time T4 is greater than the third preset time T3.
For example, the third preset time T3 may be 1 minute, and the fourth preset time T4 may be 3 minutes. Also, the person evacuation prompt may be the same as or different from the person departure prompt. Thus, the safety of personnel in the sterilization mode operation is further improved.
According to some embodiments of the present invention, as shown in fig. 1, the control method of the air conditioner further includes turning off the sterilization device to exit the sterilization mode, and turning on a fresh air device to start a fresh air mode.
The air conditioner needs to be provided with a fresh air pump, so that outdoor fresh air can be pumped into a room, the content of harmful substances possibly generated in the operation of the sterilization device in the air can be reduced, for example, when the sterilization device is an ultraviolet sterilization device, the fresh air is conveyed, the concentration of ozone generated in the room due to ultraviolet sterilization can be effectively reduced, and the use safety of the air conditioner is improved.
According to some embodiments of the present invention, as shown in fig. 1, the turning on the fresh air device to start the fresh air mode includes:
acquiring the air volume C of the fresh air device and the height H of a room where an air conditioner is located;
calculating the running time t of the fresh air device according to the air volume C and the height H of the room;
and controlling the fresh air device to start and operate the operation time t.
Wherein, the operating time t of new trend device is: t is H × S/C. In other words, the product of the room area S and the height H is divided by the ratio of the air volume C, and the ratio is the operation time t of the fresh air device.
For example, the room height H may be measured by a room height measuring device, or may be input by a user. If the air conditioner is installed with the room height measuring device and the user does not input the height H of the room, the height of the room is defaulted to 3 meters. And, when starting new trend mode, the new trend device is with the maximum wind speed operation, the new trend device is the fan.
In this way, after the operation time t of the fresh air device, harmful substances (such as ozone generated during ultraviolet sterilization) possibly generated in the air conditioner sterilization process can be discharged, so that the safety of the living life of the user can be ensured.
According to some embodiments of the present invention, as shown in fig. 1, the operation time t of the fresh air device is: t is H × n2 × S/C, where n2 is a second correction value. The second correction value n2 is 1.5-2, and the running time t of the fresh air device can be further adjusted according to actual use requirements through setting the second correction value n2, so that the safety of a user is better guaranteed, and the applicability of the air conditioner is improved.
According to some embodiments of the present invention, as shown in fig. 1, after the fresh air device is turned off to exit the fresh air mode, a sterilization completion prompt is issued. Therefore, the user can be informed that the sterilization in the room where the air conditioner is located is completed, and the automation of the air conditioner is increased.
An air conditioner according to an embodiment of the present invention is described below with reference to the accompanying drawings. The air conditioner 1 according to the embodiment of the present invention includes a case 100, an air conditioning module, a sterilizing device, and a control device.
As shown in fig. 2, the air conditioning module, the sterilization device and the control device are disposed in a casing 100, and the control device is connected to the air conditioning module and the sterilization device, respectively, and the control device calculates the number of times of air supply according to the operating power of the sterilization device and the area of the room where the air conditioner 1 is located, and controls the air conditioning module to supply air according to the number of times of air supply when the sterilization device is operating.
The control device is provided with an MCU (Microcontroller Unit) to store the area S of the room. The air conditioning module contains the conventional function of air conditioner, for example, the regulation etc. of refrigeration, heating, wind speed and wind direction, the air conditioning module still includes wireless communication module, for example, wifi, zigbee, bluetooth etc. for accept the signal that user's pronunciation, remote controller or application program (APP) sent. And, the air conditioning module has some detecting means, such as a human body detecting means 200, for detecting whether a person exists in a room,
according to the air conditioner 1 of the embodiment of the invention, the sterilization effect and the sterilization range can be considered at the same time, and the safety of the living environment is improved.
According to some embodiments of the present invention, as shown in fig. 2, the sterilization device includes an ultraviolet lamp 400 and a telescopic bracket.
