[0043] As air conditioners become more common in daily life, users' use of air conditioners varies depending on the installation scenario and their perception of temperature. Therefore, the adjustable speed of the air guide plate of the air conditioner will become more important. The air guide plate of the current air conditioner products on the market has a fixed speed, that is, the cyclic change cycle of the wind direction is fixed. It is fixed by the air conditioner manufacturer when the air conditioner product leaves the factory and cannot be changed by the user. In actual application, the fixed air outlet speed and direction cannot meet the user's comfort needs.

[0044] In order to solve the above problems, the present invention provides an air guide plate operation control method for an air conditioner. The air conditioner includes a fan, a stepper motor and an air guide plate.

[0045] Reference Figure 1 , the air conditioner air guide plate operation control method comprises the following steps:

[0046] S100, obtaining the operating mode data of the air conditioner and the fan gear speed data;

[0047] S200, obtaining a calculation formula for the air guide plate operating frequency; wherein different operating mode data and fan gear speed data correspond to different calculation formulas for the air guide plate operating frequency;

[0048] S300, calculating the air guide plate operating frequency according to the air conditioner operating mode data, the fan gear speed data and the air guide plate operating frequency calculation formula;

[0049] S400, controlling the stepper motor M1 to drive the air guide plate to rotate according to the operating frequency of the air guide plate.

[0050] In this embodiment, the operating mode data and fan gear speed data of the air conditioner can be collected by the signal acquisition unit 10, which can be collected by a data acquisition card, a programmable logic controller, an embedded system or a sensor and other devices. The operating mode of the air conditioner is a digital signal, and the fan gear speed is an analog signal, so the corresponding signal acquisition unit 10 can be selected for data collection. At the same time, the calculation formula of the air guide plate operating frequency can also be obtained. The calculation formula can be input by an external device, or the calculation formula can be preset in the memory 40 and obtained by reading the memory 40.

[0051] It is understandable that in order to improve the user's comfort in actual application, the air guide plate operating frequency calculation formula can be determined based on the human comfort experiment. Because the human comfort will also change under different operating modes and fan gear speeds of the air conditioner, the air guide plate operating frequency needs to be adjusted to change the air outlet speed of the air conditioner, thereby improving the human comfort; therefore, the air guide plate operating frequency calculation formula corresponding to the highest human comfort under different operating modes and fan gear speeds of the air conditioner can be stored in the memory 40, and then the corresponding air guide plate operating frequency calculation formula is queried based on the operating mode data of the air conditioner and the fan gear speed data, so as to calculate the air guide plate operating frequency according to the air guide plate operating frequency calculation formula. At this time, the stepper motor M1 can be controlled to work according to the calculated operating frequency of the air guide plate to drive the air guide plate to rotate at a preset frequency; in different operating modes and different fan speeds, driving the air guide plate to rotate at different frequencies can make the user feel more comfortable; for example, the operating modes of the air conditioner may include air supply mode, cooling mode and heating mode. When the fan speed is the same, the rotation frequency of the air guide plate in the cooling mode and the heating mode is different. Considering the user's comfort, in the cooling mode, a higher wind speed is usually required to quickly reduce the indoor temperature, so the air guide plate can appropriately increase the rotation frequency to ensure that the cold air is evenly distributed; in the heating mode, a lower wind speed can make the hot air diffuse more slowly to avoid local overheating, so the rotation frequency of the air guide plate can be appropriately reduced. The specific operating frequency of the air guide plate can also be calculated based on the user's actual experience of comfort. In addition, this solution does not require any buttons to be added to the original air conditioner remote control, making the control more convenient and quick.

[0052] The technical solution of the present invention obtains the operating mode data of the air conditioner, the fan gear speed data and the air guide plate operating frequency calculation formula; then calculates the air guide plate operating frequency according to the air conditioner operating mode data, the fan gear speed data and the air guide plate operating frequency calculation formula, so that the stepper motor M1 can be controlled to drive the air guide plate to rotate according to the air guide plate operating frequency. This solution can control the air guide plate to have different operating speeds under different operating modes of the air conditioner and different fan speed states, which meets the actual use of users and improves the user's comfort.

[0053] In one embodiment, the step of obtaining the calculation formula for the wind plate operating frequency specifically includes:

[0054] Acquire the comfort test data, and query the preset air guide plate operation frequency calculation formula based on the comfort test data, the air conditioner operation mode data and the fan gear speed data.

[0055] In this embodiment, the comfort experiment is usually to evaluate people's comfort under specific environmental conditions. In this way, the most suitable wind speed under different air conditioner operation mode data and fan gear speed data can be obtained through the user's comfort experiment data, thereby obtaining the corresponding air deflector operation frequency calculation formula. In this way, the air deflector operation frequency calculation formula can be written into the memory 40 for reading; in actual applications, there will be multiple air deflector operation frequency calculation formulas written into the memory 40. The preset air deflector operation frequency calculation formula in the memory 40 can be queried according to the real-time operation mode data of the air conditioner and the fan gear speed data, and the corresponding air deflector operation frequency calculation formula is selected for calculation to obtain the air deflector operation frequency, thereby controlling the air deflector.

[0056] Furthermore, in one embodiment, the comfort experimental data includes at least one of ambient temperature, ambient humidity and air flow velocity.

[0057] In this embodiment, the comfort experiment is usually a study to evaluate the impact of products, environments or activities on human comfort. According to the actual application scenario, the parameters affecting human comfort in this embodiment can be at least one of ambient temperature, ambient humidity and air flow velocity; of course, in different application scenarios, the parameters affecting human comfort can also include other parameters, such as pressure, vibration and light intensity, etc., and the specific experiment can be carried out according to the actual situation. For ambient temperature, ambient humidity and air flow velocity, temperature sensors, hygrometers and gas flow rate sensors can be used to measure, and then let users perform activities under different conditions or be exposed to different environments, record their comfort evaluation, analyze and statistically process the collected data, and use methods such as mean value, standard deviation, variance analysis, etc. to compare the comfort differences under different conditions, so as to derive the corresponding air guide plate operation frequency calculation formula.

[0058] In one embodiment, when executing the step of obtaining the operating mode data of the air conditioner and the fan gear speed data, it also includes:

[0059] Acquire a human body position signal and determine a blowing range according to the human body position signal;

[0060] The step of controlling the stepper motor M1 to drive the air guide plate to rotate according to the operating frequency of the air guide plate specifically includes:

[0061] According to the operating frequency of the air guide plate and the blowing range, the stepper motor M1 is controlled to drive the air guide plate to rotate within a preset range.

[0062] In this embodiment, the user's position can be detected by the human body detection sensor 50, and the blowing range of the air conditioner can be determined by obtaining the human body position signal output by the human body detection sensor 50. The blowing range can be directed to the human body or not, and can be set according to actual conditions and user needs; for example, if the user prefers direct blowing, the blowing range can be determined as the range directed to the human body, or if the user prefers not to blow directly, the blowing range can be determined as the range not directed to the human body. In this way, in this embodiment, the stepper motor M1 is controlled to drive the air guide plate to rotate within a preset range according to the operating frequency of the air guide plate and the blowing range, which can further improve the user's comfort.

[0063] In one embodiment, the operation modes of the air conditioner include air supply mode, cooling mode and heating mode, and the fan gear speed data includes a silent gear, multiple normal working gears and a strong gear.

[0064] In this embodiment, the operation mode of the air conditioner may include three modes: air supply mode, cooling mode, and heating mode. The operation mode of the air conditioner may also be increased or modified according to the actual situation and user needs. In this embodiment, the multiple ordinary working gears of the fan gear may be divided into two gears, three gears, four gears, five gears, and six gears. The specific number of gears may also be increased or modified according to the actual situation and user needs. The corresponding relationship between the specific operation mode, fan gear, calculation logic, and air guide plate speed may refer to the following table:

[0065] Operation Mode Fan gear Calculation Logic Air guide plate speed ms / step Air supply mode Silent mode Air guide plate speed = 0.5√600ms / step 12 Cooling mode Silent mode Air guide plate speed = 0.4√600ms / step 10 Heating mode Silent mode Air guide plate speed = 0.4√600+1ms / step 11 Air supply mode Second gear Air guide plate speed = 0.5√700-1ms / step 11 Cooling mode Second gear Air guide plate speed = 0.4√700-1ms / step 9 Heating mode Second gear Air guide plate speed = 0.4√700ms / step 10 Air supply mode Third gear Air guide plate speed = 0.5√800-4ms / step 10 Cooling mode Third gear Air guide plate speed = 0.4√800-4ms / step 7 Heating mode Third gear Air guide plate speed = 0.4√800-3ms / step 8 Air supply mode Four gears Air guide plate speed = 0.5√900-6ms / step 9 Cooling mode Four gears Air guide plate speed = 0.4√900-6ms / step 6 Heating mode Four gears Air guide plate speed = 0.4√900-5ms / step 7 Air supply mode Five gears Air guide plate speed = 0.5√950-7ms / step 8 Cooling mode Five gears Air guide plate speed = 0.4√950-7ms / step 5 Heating mode Five gears Air guide plate speed = 0.4√950-6ms / step 6 Air supply mode Sixth gear Air guide plate speed = 0.5√1030-8ms / step 7 Cooling mode Sixth gear Air guide plate speed = 0.4√1030-7ms / step 5 Heating mode Sixth gear Air guide plate speed = 0.4√1030-6ms / step 6 Air supply mode Strong gear Air guide plate speed = 0.5√1150-11ms / step 6 Cooling mode Strong gear Air guide plate speed = 0.4√1150-7ms / step 3 Heating mode Strong gear Air guide plate speed = 0.4√1150-6ms / step 4 ;

[0066] The unit of the air guide plate speed is ms / step, and the air guide plate speed in the table is an approximate integer. The speed of the silent gear is 600r / min, the speed of the second gear is 700r / min, the speed of the third gear is 800r / min, the speed of the fourth gear is 900r / min, the speed of the fifth gear is 950r / min, the speed of the sixth gear is 1030r / min, and the speed of the super gear is 1150r / min, where r / min is revolutions per minute.
