Air conditioning apparatuses are capable of adjusting parameters of indoor environment, such as temperature, humidity, carbon dioxide concentration, etc., which are related to air quality or comfort, and thus have become a type of electric appliances that are not available in life. In recent years, air pollution caused by industrial and agricultural development is more and more serious, and outdoor air pollution also can seriously affect indoor air, so that the purification of the indoor air is very necessary, but the air conditioning equipment in the related art cannot scientifically and accurately purify the indoor air.
Based on this, in a first aspect, at least one embodiment of the present disclosure provides a control method of an air conditioning device, please refer to fig. 1, which shows a flow of the method, including step S101 and step S103.
The method is applied to air conditioning equipment such as an air conditioner, a fresh air machine and the like, and particularly can be applied to a main control board of the air conditioning equipment or a special Micro Control Unit (MCU) for executing the method. The air conditioning equipment is provided with a PM2.5 sensor, the PM2.5 sensor can collect PM2.5 concentration values of the environment where the air conditioning equipment is located, and under the common condition, the air conditioning equipment is installed indoors, so that the PM2.5 can collect the indoor PM2.5 concentration values. The air conditioning equipment has an IFD (intense field direct) purification function, i.e., a strong electric field using a dielectric material as a carrier. Among them, dielectrics are insulators and also effective carriers of electric fields. The dielectric material forms a honeycomb hollow micro-channel, the dielectric wrapping electrode plates form a strong electric field in the channel, the dielectric wrapping electrode plates exert huge attraction on charged particles moving in the air, can adsorb almost 100% of airborne particles while generating minimum air flow impedance, has a remarkable removal effect on particulate pollutants such as PM2.5 and the like, and can collect and kill bacteria, microorganisms and the like attached to the particles in the strong electric field, so that the IFD has a high-efficiency sterilization effect while efficiently removing the PM 2.5. Accordingly, the air conditioning apparatus has an air cleaning member, such as a filter cartridge, etc., which performs an IFD cleaning function.
In step S101, a PM2.5 concentration value collected by the PM2.5 sensor is acquired.
The PM2.5 sensor can be electrically connected with a main control board or an MCU (microprogrammed control unit) executing the method, so that the main control board or the MCU can acquire the PM2.5 concentration value acquired by the PM2.5 sensor. The PM2.5 concentration value collected by the PM2.5 sensor can be obtained in real time, and the PM2.5 concentration value collected by the PM2.5 sensor can also be obtained according to a certain frequency.
It is understood that, after the PM2.5 concentration value is acquired, the value may be deleted after use, or the record may be saved after use.
In step S102, an air purification instruction is determined according to the PM2.5 concentration value and a PM2.5 concentration threshold corresponding to the current operation mode of the air conditioning equipment.
Wherein, air conditioning equipment can have the automatic mode of purifying, remind the mode such as mode automatically, wherein, the automatic mode of purifying can be for the mode of automatic start IFD purification performance, and the mode is for the mode of manual start IFD purification performance automatically to remind the mode. In the automatic purification mode, an air purification instruction for automatically starting and stopping the IFD purification function can be determined according to the relation between the PM2.5 concentration threshold value corresponding to the automatic purification mode and the obtained PM2.5 concentration value; in the automatic reminding mode, an air purification instruction for starting and stopping a prompt message can be determined according to the relation between the PM2.5 concentration threshold value corresponding to the automatic purification mode and the obtained PM2.5 concentration value, and the prompt message can be used for prompting a user to start and stop an IFD purification function.
Optionally, when a duration of a difference relationship between the PM2.5 concentration value and the PM2.5 concentration threshold value reaches a duration threshold value corresponding to the PM2.5 concentration threshold value, the air purification instruction corresponding to the difference relationship is determined. Therefore, the inaccurate PM2.5 detection is avoided, or the detection result is suddenly changed to cause the generation of wrong instructions, and the accuracy and the stability of the air purification instruction are improved. The time length thresholds corresponding to different concentration thresholds may be the same or different, and preferably, the time length threshold corresponding to each concentration threshold may be within a range of 1-15min, preferably 8min or 10 min.
In addition, the operation mode adjustment instruction can be received under the condition that the air conditioning equipment is shut down or other functions except the IFD purification function are operated; and adjusting the current operation mode of the air conditioning equipment according to the operation mode adjusting instruction. The mode adjustment instruction may be generated according to a user operation, for example, by a user operation on a remote controller, or by a user operation on control software installed on a binding device (e.g., a mobile phone, etc.). The other functions besides the IFD purification function can be the functions of refrigeration, heating, fans, fresh air and the like of the air conditioner. By adjusting the current operation mode, the air conditioner can be operated in an automatic purification mode, an automatic reminding mode or other modes.
In step S103, according to the air purification instruction, the air conditioning device is controlled to turn on or off the IFD purification function or turn on or off a prompt message for prompting a user to turn on the IFD purification function.
Specifically, under the condition that the air conditioning equipment does not operate other functions except the IFD purification function, the air conditioning equipment is controlled to start and stop the IFD purification function, so that the air conditioning equipment is in a state that the IFD purification function is independently started; the IFD purification function is opened and closed to air conditioning equipment, so that air conditioning equipment is the state that IFD purification function and other functions are mixed. And at the moment, the air conditioning equipment does not operate other functions except the IFD purification function, so that the upper and lower air guide can keep the state of the first electrifying default refrigeration direct-blow preventing angle, the left and right air sweeping keeps the state of the first electrifying default closing position, and the rotating speed of the inner fan keeps the state of the first electrifying default automatic windshield. For example, if the air conditioning apparatus operates a function other than the IFD purification function, the up-down air guide, the left-right air sweeping, the rotation speed of the inner fan, the electric auxiliary heating, and the like can be operated according to the setting of the user.
It should be noted that after the air conditioning equipment automatically starts the IFD purification function according to the air purification instruction, the air conditioning equipment may be controlled to turn off the IFD purification function in the case that the air conditioning equipment is turned off, powered off, or receives a purification stop instruction. The automatically activated IFD purge function may thus be manually turned off.
Under the condition that an air purification instruction is used for controlling the air conditioning equipment to start and stop the prompt message, and under the condition that the air purification instruction is used for controlling the air conditioning equipment to generate the prompt message, the air conditioning equipment is controlled to send the prompt message to binding equipment, so that the binding equipment displays and/or plays the prompt message within preset time; and under the condition that the air purification instruction is used for controlling the air conditioning equipment to close the prompt message, controlling the air conditioning equipment to send a closing message to binding equipment so as to stop the binding equipment from displaying and/or playing the prompt message.
The binding device can be a smart phone, a television and the like, and a software application program for controlling the air conditioning device can be pre-installed on the binding device, so that prompt messages can be conveniently received and displayed, and control instructions can be sent to the air conditioner. The preset time period may be in the range of 1-10min, preferably 5 min.
It is noted that the time interval between two adjacent sending of the prompting message to the binding device may be set in advance, for example, in the range of 0.5-24h, preferably 10 h. And controlling the air conditioning equipment to send a closing message to the binding equipment so as to stop the display and/or play of the prompting message by the binding equipment under the condition that the IFD purification function of the air conditioning equipment is started within the preset time after the air conditioning equipment sends the prompting message to the binding equipment. Therefore, the prompt message can be automatically closed when the necessity of the prompt message is lost, and the excessive disturbance of a user is avoided.
According to the method, firstly, a PM2.5 concentration value acquired by a PM2.5 sensor of the air conditioning equipment is acquired, an air purification instruction is further determined according to the PM2.5 concentration value and a PM2.5 concentration threshold value corresponding to the current operation mode of the air conditioning equipment, and finally, the air conditioning equipment is controlled to start and stop an air conditioning function or a prompt message for reminding a user to start an IFD purification function is controlled according to the air purification instruction. Because PM2.5 concentration value can accurate collection by the PM2.5 sensor, and the air purification instruction is confirmed according to the PM2.5 concentration threshold value that current operating mode of air conditioning equipment corresponds, consequently scientific and reasonable can be accurate purify the air, avoid excessively purifying moreover and lead to the energy extravagant.
In some embodiments of the present disclosure, when the current operation mode of the air conditioning equipment is the automatic purification mode and the automatic reminding mode, the air purification instruction may be determined according to the PM2.5 concentration value and the PM2.5 concentration threshold corresponding to the current operation mode of the air conditioning equipment in the following manner, respectively.
And under the condition that the current operation mode of the air conditioning equipment is an automatic purification mode, determining an air conditioning instruction for controlling the air conditioning equipment to start and stop an IFD purification function according to the PM2.5 concentration value, a first threshold value and a second threshold value, wherein the first threshold value is smaller than the second threshold value.
Optionally, in a case that the concentration value of PM2.5 is greater than or equal to the second threshold, determining an air conditioning instruction for controlling the air conditioning equipment to start an IFD purification function; determining an air conditioning command for controlling the air conditioning equipment to turn off the IFD purification function in the case that the PM2.5 concentration value is smaller than the first threshold value; and determining an air conditioning instruction for controlling the air conditioning equipment to maintain the current on-off state of the IFD purification function when the concentration value of the PM2.5 is greater than or equal to the first threshold value and smaller than the second threshold value.
Wherein the first threshold value can be 35-75 μ g/m3In the range, it is preferably 50. mu.g/m3The corresponding time length threshold value can be in the range of 1-15min, and is preferably 8 min.
