The invention provides a linkage control method of an air conditioner and a fan. The air conditioner may be a split wall-mounted air conditioner, a split floor-type air conditioner, an integral air conditioner (e.g., a window air conditioner, a mobile air conditioner, a dehumidifier, etc.), a central air conditioner, or the like. The fan may be, but is not limited to, a ceiling fan, a floor fan, a table fan, or the like.
Referring to fig. 1, in an embodiment of the present invention, the method for controlling the air conditioner and the fan in a linkage manner includes the following steps:
and step S1, the air conditioner receives the linkage instruction and establishes the linkage relation with the fan according to the linkage instruction.
Referring to fig. 2 and 3, in the present embodiment, the coordinated control system of the air conditioner 10 and the fan 20 includes the air conditioner 10, the fan 20, and the operation input module 30. The operation input module 30 is connected to the air conditioner 10 for communication only with the air conditioner 10. Of course, the operation input module 30 may indirectly control the fan 20 through the air conditioner 10. In this embodiment, a user inputs a linkage instruction on the operation input module 30 to establish a linkage relationship between the air conditioner 10 and the fan 20; after the linkage relationship is established, the air conditioner 10 and the fan 20 are in a master-slave mode, the air conditioner 10 is a master module, the fan 20 is a slave module, and the air conditioner 10 can send a control signal to the fan 20 to control the operating state of the fan 20. Of course, the user may also input a mode setting command on the operation input module 30 to set an operation mode of the air conditioner 10 (such as, but not limited to, a cooling mode, a heating mode, etc.) and an operation mode of the fan 20 (such as, but not limited to, a shaking head, a gear shifting, etc.), and input a parameter setting command to set respective operation parameters of the air conditioner 10 and the fan 20, etc.
It should be noted that, in this embodiment, the operation input module 30 may be independent, for example, the operation input module 30 may be a remote controller of the air conditioner 10, or may be an intelligent terminal (for example, but not limited to, a smart phone, a smart watch, a smart bracelet, etc.) capable of remotely controlling the air conditioner 10, as shown in fig. 3; and may also be part of the air conditioner 10, such as an operating panel of the air conditioner 10.
The communication connection between the air conditioner 10 and the fan 20 may be a wired connection (for example, RS232 communication, RS485 communication, PLC communication, or CAN bus communication), or a wireless connection (for example, WIFI communication, bluetooth communication, infrared communication, radio frequency communication, or ZigBee communication).
Only one fan 20 may be provided, or a plurality of fans may be provided at the same time. In particular, when a plurality of fans 20 are provided, the plurality of fans 20 are communicatively connected to the air conditioner 10 in parallel, as shown in fig. 2, that is, each fan 20 is individually linked to the air conditioner 10, and the air conditioner 10 can selectively control any fan 20 to operate in a linked manner.
And S2, the air conditioner acquires the real-time temperature of the indoor environment, acquires the fan rotating speed corresponding to the delta T according to a first preset rule when the absolute value delta T of the difference between the preset target temperature and the real-time temperature is greater than or equal to a first preset threshold delta T1, controls the fan to start to operate at the acquired fan rotating speed according to the linkage relation, and simultaneously controls the fan to start to cyclically swing air. Wherein, the larger Δ T corresponding to the larger fan speed is larger.
In this embodiment, the real-time temperature may be detected by a temperature sensor disposed at an air return opening of the air conditioner, or may be detected by a temperature sensor disposed at a fan or an independent operation input module.
In this embodiment, when a user needs to cool down the room quickly in hot summer or to warm up the room quickly in cold winter, for example, the user turns on the air conditioner to cool or heat the room. It can be understood that after the air conditioner is turned on, if the real-time temperature of the indoor environment is greatly different from the target temperature of refrigeration or heating, the diffusion rate of cold air or hot air sent by the air conditioner in the room needs to be increased, so that the temperature in the room can be uniformly reduced or increased, and thus, a user can feel the reduction or increase of the room temperature at any position in the room, and the user experience is improved.
In the technical scheme of the invention, specifically, when the Δ T is greater than or equal to the Δ T1, it is considered that the difference between the real-time temperature and the target temperature is large, at this time, the air conditioner controls the fan to be started and operated in a linkage manner, so that the air flow of the indoor space is accelerated by the fan while the air conditioner performs cooling air supply or heating air supply, and the fan is controlled to operate in a circulating air swing manner, so that the air of the indoor space flows in a large range, the diffusion of cold air or hot air of the air conditioner in the indoor space is accelerated, the temperature regulation rate of the air conditioner is improved, and the temperature regulation range of the air conditioner is expanded. In addition, cold air directly sent out by the air conditioner is over-cooled and over-heated, so that the cold air is uncomfortable and the health is damaged when the cold air is directly blown to a human body, and the temperature adjusting comfort can be improved through diffusion adjustment of the fan.
In addition, in this embodiment, as the air conditioner is operated, the real-time temperature of the indoor space is gradually decreased by cooling or increased by heating, that is, the real-time temperature is changed, and thus the Δ T is also changed. It can be understood that, in the initial stage of temperature adjustment, the Δ T is large, and a fan is required to diffuse cold air or hot air output by the air conditioner more quickly at a large wind speed; and in the later stage of temperature adjustment, the delta T is smaller, at the moment, the temperature is close to the temperature expectation of a user, the user can obtain better comfortable experience, the demand on cold air or hot air diffusion is weakened, the rotating speed of the fan can be reduced, and the energy consumption is saved.
In the present invention, the first preset rule has a plurality of kinds, and the method for controlling the linkage of the air conditioner and the fan may be selected to determine the rotation speed of the fan, three of which are listed below:
first, for a fan with multiple fan rotational speed stages, under the first preset rule, in the step S2, the step of obtaining the fan rotational speed corresponding to the Δ T according to the first preset rule, and controlling the fan to start and operate at the obtained fan rotational speed according to the linkage relationship specifically includes:
and the air conditioner determines the threshold gear matched with the delta T, acquires the fan rotating speed gear corresponding to the determined threshold gear, and controls the fan to operate according to the acquired fan rotating speed gear. The threshold value of the threshold value gear corresponding to the fan speed gear with the higher fan speed is larger.
It can be understood that the fan speeds corresponding to different fan speed gears are different. Taking a fan with three fan rotation speed stages as an example, when the Δ T is greater than or equal to the Δ T1 and less than a fifth preset threshold Δ T5, the air conditioner controls the fan in a linkage manner, so that the fan operates at a first rotation speed stage; when the delta T is greater than or equal to the delta T5 and smaller than a sixth preset threshold delta T6, the air conditioner controls the fan in a linkage mode, and the fan runs at a second rotating speed gear; when the delta T is larger than or equal to the delta T6, the air conditioner controls the fan in a linkage mode, and the fan runs at a third rotating speed gear; wherein, Δ T6> Δ T5> Δ T1, the fan speed corresponding to the first gear < the fan speed corresponding to the second gear < the fan speed corresponding to the third gear. When the fan speed gear of the fan is not three, the method is analogized in turn.
Secondly, for the fan with the continuously adjustable fan rotation speed, under the second first preset rule, in the step S2, the step of obtaining the fan rotation speed corresponding to the Δ T according to the first preset rule, and controlling the fan to start and operate at the obtained fan rotation speed according to the linkage relationship specifically includes:
and the air conditioner acquires the fan rotating speed corresponding to the delta T in a table look-up mode and controls the fan to operate at the acquired fan rotating speed.
The air conditioner adopting the first preset rule generally stores a difference-fan rotation speed list, and the difference-fan rotation speed list is used for representing the one-to-one correspondence relationship between different difference sections and different fan rotation speeds. Specifically, the possible absolute value of the difference between the target temperature and the real-time temperature is divided into N (N is larger than or equal to 2) sections, a fan rotating speed is set corresponding to each section, and the larger the absolute value of the difference represented by each section is, the larger the corresponding fan rotating speed is. After the air conditioner obtains the specific delta T at a certain moment, the air conditioner is firstly compared with the difference value-fan rotating speed list, and the specific section where the specific delta T falls is judged, so that the fan rotating speed corresponding to the specific section is obtained, namely the fan rotating speed corresponding to the delta T.
A third preset rule and the first preset rule are also set corresponding to the fan with the continuously adjustable fan speed, and in the third preset rule, in the step S2, the step of obtaining the fan speed corresponding to the Δ T according to the preset rule, and the step of controlling the fan to start and operate at the obtained fan speed according to the linkage relationship includes:
s211, when the delta T is less than or equal to the delta T1, the air conditioner controls the fan to run at the minimum fan speed;
s212, when the delta T is larger than the delta T1 and smaller than a second preset threshold delta T2, the air conditioner obtains the fan rotating speed corresponding to the delta T according to a preset monotone increasing function, and the fan is controlled to operate at the obtained fan rotating speed; the Δ T2 is greater than the Δ T1;
and S213, when the delta T is larger than or equal to the delta T2, the air conditioner controls the fan to operate at the maximum fan rotating speed.
Under the first preset rule, after the air conditioner obtains a specific Δ T at a certain time, the air conditioner may substitute the specific Δ T into the monotonically increasing function to perform calculation, so as to calculate and obtain the fan rotation speed corresponding to the specific Δ T. Obviously, since the function used for the calculation is monotonically increasing, that is, the larger the Δ T, the larger the calculated fan speed. Further, to simplify the operation, the monotone increasing function is preferably a linear increasing function.
In addition, for a given model of fan, the fan speed is typically limited. In addition, in the process of calculating the fan rotation speed by using a preset monotone increasing function, when the Δ T takes the value of Δ T1, the calculated fan rotation speed should not be less than the minimum fan rotation speed of the fan, and when the Δ T takes the value of Δ T2, the calculated fan rotation speed should not be greater than the maximum fan rotation speed of the fan. Without loss of generality, the Δ T1 is typically set at around 2 ℃ and the Δ T2 is typically set between 5 ℃ and 8 ℃. Considering that, under certain specific conditions, the specific Δ T is less than or equal to the set Δ T1, or is greater than or equal to the set Δ T2, in order to avoid the phenomenon that the fan speed of the fan cannot be effectively controlled because the fan speed cannot be calculated, the air conditioner controls the fan to operate at the minimum fan speed when the specific Δ T is less than or equal to the set Δ T1, and controls the fan to operate at the maximum fan speed when the specific Δ T is greater than or equal to the set Δ T2.
In the technical solution of the present invention, the real-time temperature is preferably fed back by a portable device having temperature detection, positioning and wireless communication functions, such as, but not limited to, a remote controller or an intelligent terminal equipped with a temperature sensor.
Further, in step S2, the step of controlling the fan to turn on to cyclically swing the wind includes:
and S221, when the delta T is larger than a third preset threshold value delta T3, the air conditioner controls the fan to swing in a direction towards the temperature feedback point as the central direction of the swinging air. Wherein the Δ T3 is greater than Δ T1; the temperature feedback point is the position of the portable device.
When the Δ T is greater than the Δ T3, it indicates that the difference between the real-time temperature and the target temperature is far away, and in hot summer, for example, it indicates that the real-time temperature of the indoor space is much higher than the target temperature that the user can feel comfortable, and at this time, the user needs to get a cool experience urgently. In this embodiment, when the Δ T is greater than the Δ T3, the air conditioner may control the fan to swing in a direction toward the temperature feedback point as a center direction of the swinging wind, so as to ensure that the fan can guide the cool wind sent by the air conditioner to a location of the temperature feedback point.
Further, in step S2, the step of controlling the fan to start circulating swing further includes:
and S222, when the delta T is larger than or equal to the delta T1 and smaller than the delta T3, the air conditioner controls the fan to swing in the largest swing angle range.
It can be understood that when Δ T1 is not less than Δ T < Δ T3, it indicates that there is a certain difference between the real-time temperature and the target temperature, but it is not large, the user has a demand for realizing uniform cooling of the indoor space, but the demand for cool experience is not large, at this time, it is only necessary to control the fan to swing at the maximum swing angle range, so as to uniformly cool the indoor space through the large-range flow of the air in the indoor space, and it is not necessary to control the fan to swing at the center direction of the swing toward the temperature feedback point, so that the linkage control action of the air conditioner can be reduced, the possibility of control disorder can be reduced, and the control reliability can be improved.
It should be noted that, the magnitude relationship between the Δ T3 and the Δ T2 in the foregoing embodiment has no correlation, but in general, Δ T3 < Δ T2.
In this embodiment, further, when the fan with an adjustable wind swinging angle range is selected, the step S221 includes:
and S221a, the air conditioner obtains the swing angle range corresponding to the delta T according to a second preset rule, and the fan is controlled to swing air according to the obtained swing angle range. Wherein, the smaller swing angle range corresponds to a larger delta T.
It is understood that in hot summer, as the air conditioner is operated to cool, the real-time temperature of the indoor space is gradually decreased, i.e., the real-time temperature is changed, and thus the Δ T is also changed. In the starting stage of temperature adjustment, the delta T is larger, the requirement of a user on cold air is larger, the fan needs stronger drainage effect, the smaller the swing angle range is, the stronger the drainage effect is, and at the moment, the fan needs to be controlled to swing in the smaller swing angle range; and in the later stage of temperature adjustment, the delta T is smaller, the requirement of a user on cold air is weakened, the cold air is excessively drained to the user and even falls over, so that the user feels too cold, and at the moment, the drainage effect of the fan can be weakened by enlarging the swing angle range of the fan.
In the present invention, the second preset rule has a plurality of rules, and the air conditioner and fan linkage control method can be selected to determine the range of the swing angle, two of which are listed below:
in a first type, under the first second preset rule, the step S221a specifically includes:
and the air conditioner acquires the wind swinging angle range corresponding to the delta T in a table look-up manner, and controls the fan to swing wind according to the acquired wind swinging angle range.
The air conditioner adopting the second preset rule usually stores a difference-swing angle range list, and the difference-swing angle range list is used for representing the one-to-one correspondence relationship between different difference segments and different swing angle ranges. Specifically, a possible absolute value of a difference between the target temperature and the real-time temperature is divided into N (N is larger than or equal to 2) sections, a swing wind angle range is set corresponding to each section, and the larger the absolute value of the difference represented by each section is, the larger the corresponding swing wind angle range is. After the air conditioner obtains the specific delta T at a certain moment, the air conditioner is firstly compared with the difference value-swing angle range list, and the specific section where the specific delta T falls is judged, so that the swing angle range corresponding to the specific section is obtained, namely the swing angle range corresponding to the delta T. The following table is a list of the difference-yaw angle ranges for one embodiment:
| ΔT | below 1 deg.C | 2～3℃ | 4～5℃ | 6～7℃ | Above 8 DEG C |
| Range of angle of pendulum wind | -75°～75° | -50°～50° | -30°～30° | -15°～15° | 0 degree (stop pendulum wind) |
Second, under the second preset rule of the second kind, the step S221a includes:
and S2211, when the delta T is larger than the delta T3 and smaller than a seventh preset threshold value delta T7, the air conditioner acquires a swing wind angle range corresponding to the delta T according to a preset monotone decreasing function, and controls the fan to swing wind according to the acquired swing wind angle range.
It is understood that the Δ T7 is greater than the Δ T3. Under the second preset rule, after the air conditioner obtains the specific Δ T at a certain time, the air conditioner can substitute the specific Δ T into the monotonically decreasing function to calculate, so as to obtain the swing angle range corresponding to the specific Δ T through calculation. Obviously, since the function used for the calculation is monotonically decreasing, that is, the larger the Δ T, the smaller the calculated range of the yaw angle. Further, to simplify the operation, the monotonic decreasing function used is preferably a linear decreasing function.
In addition, under the second preset rule, the step S221a further includes:
