Detailed Description
In order that the above objects, features and advantages of the present invention can be more clearly understood, a more particular description of the invention will be rendered by reference to the appended drawings. It should be noted that the embodiments and features of the embodiments of the present application may be combined with each other without conflict.
In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, however, the present invention may be practiced otherwise than as specifically described herein, and thus the scope of the present invention is not limited by the specific embodiments disclosed below.
As shown in fig. 1, an embodiment of an aspect of the present invention provides an air conditioner 1 capable of achieving a non-wind-sensing function and making a spatial temperature distribution more uniform, where the air conditioner 1 is, for example, a central air conditioner, and more particularly, a ducted air conditioner. Besides a compressor, a throttling device, an indoor heat exchanger and an outdoor heat exchanger which are involved in the refrigeration cycle, a fan 12 facing the indoor heat exchanger is also arranged in the air conditioner 1 so as to blow air which exchanges heat with the indoor heat exchanger out of the air conditioner 1 through an indoor air outlet, and an air guide assembly 14 is also arranged at the indoor air outlet so as to guide airflow to flow out along the direction of the air guide assembly 14, so that the air outlet direction is adjusted. Furthermore, in order to ensure the non-wind effect, a part of the air guiding plates of the air guiding assembly 14 may be provided with air dispersing holes to reduce the direction restriction on the air flow flowing through the part of the air guiding plates, which is helpful for dispersing the air flow and reducing the wind speed.
The air conditioner 1 is also provided with a controller 16 to control the operation of the various structures of the air conditioner 1. Specifically, the controller 16 is configured to control the air guide assembly 14 to operate so that the airflow from the air conditioner 1 changes within a range avoiding a moving object area, which is an area of the target area where the moving object is located, when the air conditioner 1 is in the no-wind-feeling mode and the moving object is present in the target area for the no-wind-feeling function. By controlling the operation of the air guide assembly 14 through the controller 16, the air flow blown out from the air conditioner 1 can be changed within a range of avoiding a moving object area, specifically, the change of the direction (namely the air outlet direction) of the air flow, so that the non-wind-sensation effect and the uniformity of the spatial temperature distribution are both considered, and the comfort of user experience is improved.
In addition, in order to improve the uniformity of the spatial temperature distribution, the controller 16 is also configured to perform different wind outlet speed controls for different indoor ambient temperatures. The method comprises the steps of firstly introducing a comfortable temperature range, wherein the comfortable temperature range represents the temperature range when the air conditioner 1 ℃ has effect on the adjustment of the indoor environment temperature, specifically, the indoor environment temperature is not in the comfortable temperature range, the temperature range respectively corresponds to the higher room temperature and the lower room temperature during the refrigeration and heating, for example, the comfortable temperature range can reach the preset temperature from minus infinity during the refrigeration, when the indoor environment temperature is higher than the preset temperature, the room temperature is considered to be higher and is not in the comfortable temperature range, the requirement for accelerating the realization of uniform distribution of the space temperature is stronger at the moment, after the indoor environment temperature enters the comfortable temperature range, the requirement is obviously reduced, and the adjustment priority of the comfortable temperature range enables the air-free effect. Based on this, the controller 16 can control the outlet wind speed of the air conditioner 1 to be greater than the non-wind-sensing wind speed when determining that the indoor environment temperature is not within the comfortable temperature range, and control the outlet wind speed to be less than or equal to the non-wind-sensing wind speed when determining that the indoor environment temperature is within the comfortable temperature range, so as to reasonably meet the above regulation requirement. The non-wind-sensing wind speed represents that when the non-wind-sensing function is realized, the maximum wind outlet speed of the air conditioner in a specified space range is 0.3m/s, and the wind outlet speed is less than or equal to the non-wind-sensing wind speed, specifically, the wind outlet speed is not more than 0.3m/s within a height range of 0-2 m at a position 2.5m away from the air conditioner in the horizontal direction.
To this end, the controller 16 according to the embodiment of the present invention may take into account the non-wind-sensing effect and the uniformity of the spatial temperature distribution based on the control of changing the airflow and limiting the wind speed of the outlet wind.
The following first develops details regarding the control of the varying air flow:
In some embodiments, the air deflection assembly 14 comprises a first air deflection assembly.
Furthermore, the first air guide assembly can be composed of a vertical air guide plate extending along the vertical direction, namely the vertical air guide assembly, and the air flow can be changed in the left-right direction by controlling the first air guide assembly to swing left and right. The first air guide assembly can also be composed of a horizontal air guide plate extending along the horizontal direction, namely the horizontal air guide assembly, and the air flow can be changed in the up-down direction by controlling the up-down swing of the first air guide assembly. Of course, the first air guiding assembly may also be composed of air guiding plates extending along other directions, as long as the air outlet direction of the air conditioner 1 can be adjusted in a certain direction.
In some embodiments, the controller 16 is specifically configured to control the first air guiding assembly to swing within a set angle range, so as to guide the airflow from the air conditioner 1 to change within a range of avoiding the moving object area. In this case, the first air guide assembly has a function of guiding the direction of the airflow to improve the uniformity of the spatial temperature distribution, so that the requirement for the direction adjustment function of the first air guide assembly is high, and the requirement for reducing the wind speed is met, so that the air guide plate of the first air guide assembly is not provided with the air dispersing holes.
With respect to moving object region
In some embodiments, the moving object may be a human or an animal to meet a variety of temperature regulation scenario requirements.
In some embodiments, to detect the moving object region, the air conditioner 1 is further configured with a detector, which may be an infrared sensor or a radar sensor, or of course, the infrared sensor and the radar sensor may be disposed at the same time to improve the accuracy of the detection, and other detectors having similar functions may be selected, which are not listed here.
Further, to detect the moving object, the air conditioner 1 may further configure a communication device to be in communication connection with the wearable device, so as to receive a detection result sent by the wearable device.
It is conceivable that, regardless of the detector or the wearable device, the position information of the moving object may be processed first to obtain the moving object region, and then the moving object region is sent to the controller 16 for use (specifically, the wearable device is sent to the communication device first, and then the communication device sends the moving object region to the controller 16), or the position information of the moving object may be sent directly, so that the controller 16 determines the moving object region. Of course, it will be obvious to those skilled in the art that the air conditioner 1 may be configured with the above-mentioned detector and communication device at the same time to improve the flexibility and accuracy of detection.
Further, since the position of the moving object is likely to change, and the moving object area is likely to change accordingly, the controller 16 may acquire the moving object area every first preset time period, so as to adjust the operation of the air guiding assembly 14 accordingly. The first preset duration is an average duration expected to change the position of the mobile object, and may be obtained through statistics or set by a user.
About a set angle range
in some embodiments, the controller 16 determines the set angle range by obtaining a moving object limit angle θ max, and recording an angle range from 0 to θ max as a moving object area, determining that the moving object limit angle θ max, the limit wind guiding angle θ and the first correction angle γ 1 satisfy θ max < θ and (θ max + γ 1) < θ, and taking the angle range from (θ max + γ 1) to θ as the set angle range, wherein the limit wind guiding angle θ is the maximum wind guiding angle of the first wind guiding component.
In this embodiment, the position of the moving object is uniformly expressed by a position angle, the position angle adopts the same direction standard, for example, the center of an indoor air outlet of the air conditioner 1 is taken as a vertex, a reference ray is guided along the surface of the air conditioner 1, and a position ray is guided through the vertex and the center point of the moving object, so that the included angle formed by the reference ray and the position ray is the position angle of the moving object, the number of the moving objects can be at least one, so that the obtained position angle is at least one, and the largest angle is taken as a moving object limit angle θ max, so that the moving object area can be expressed in an angle range from 0 to θ max.
Further, the value range of the first correction angle γ 1 is 0 ° to 40 °, and further 0 ° to 30 °, and the final value thereof can be selected within the range according to the actual situation, and is pre-stored in the controller 16, and the user can also be given the authority to set or modify the first correction angle γ 1 autonomously.
Further, the controller 16 is further configured to determine that the moving object limit angle θ max, the limit wind guiding angle θ and the first correction angle γ 1 satisfy the condition that θ max is not more than θ and (θ max + γ 1) is not less than θ, and take the angle range from θ max to θ as the set angle range, that is, in the case that (θ max + γ 1) is not less than θ, directly take the angle range from θ max to θ avoiding the moving object area as the set angle range, and do not reduce the angle range.
Furthermore, the controller 16 is further configured to determine that the limit angle θ max, the limit wind guiding angle θ, the first correction angle γ 1, and the second correction angle γ 2 satisfy θ max < θ, (θ max + γ 1) ≧ θ and (θ max + γ 2) < θ, and the first correction angle γ 1 is greater than the second correction angle γ 2 with the angle range from (θ max + γ 2) to θ as the set angle range, that is, for the case where (θ max + γ 1) ≧ θ, the second correction angle γ 2 smaller than the first correction angle γ 1 is further increased, and as long as (θ max + γ 2) < θ can be satisfied, the possibility of the air flow blowing the moving object directly is reduced as much as possible with the angle range from (θ max + γ 2) to θ as the set angle range.
further, the second correction angle γ 2 may have a value range of 0 ° to 40 °, further 0 ° to 20 °, similar to the first correction angle γ 1, and the final value thereof may also be selected within the range according to the actual situation, and is pre-stored in the controller 16, and the user may also be given the authority to set or modify the first correction angle γ 1 autonomously.
Of course, to improve the adaptability of the solution, it is obvious to those skilled in the art that multiple correction angles may be provided, and all of them fall into the protection scope of the present invention.
maxit is conceivable that, when the air guide plate of the first air guide assembly is a vertical air guide plate, the moving object may be present on the left and right of the air conditioner 1 at the same probability, and at this time, the moving object may be concentrated on the opposite direction of the reference ray, for example, the ray led out to the left of the air conditioner 1 may be used as the reference ray, but the moving object may be concentrated on the right of the air conditioner 1, and the moving object may be concentrated on the left and right.
In contrast, the set angle range can be determined in different manners depending on the cases of all the obtained position angles.
Specifically, in some embodiments, the minimum wind guide angle θ 1 and the maximum wind guide angle θ 2 of the first wind guide assembly are prestored, then for the foregoing embodiments, the limit wind guide angle θ is equal to the maximum wind guide angle θ 2, when all the position angles are obtuse angles, the minimum position angle is taken as the moving object limit angle θ max, the angle range of θ max to pi is taken as the moving object region, and the angle range of 0 to θ max is taken as the region avoiding the moving object, which can be appropriately reduced with reference to the foregoing embodiments as the set angle range.
Further, a first reference position angle θ 3 and a second reference position angle θ 4 are also prestored, and θ 1 < θ 3 < π/2< θ 4 < θ 2, i.e., the first reference position angle θ 3 represents a smaller acute angle, and the second reference position angle θ 4 represents a larger obtuse angle, when all the position angles are within the angle range of [ θ 1, θ 3 ] [ θ 4, θ 2 ], the smallest position angle is taken as the moving object lower limit angle θ max1, and the largest position angle is taken as the moving object upper limit angle θ max2, and the angle range of θ max1 to θ max2 is the region avoiding the moving object, and the region can be appropriately reduced with reference to the foregoing embodiment as a set angle range.
Of course, those skilled in the art can also make appropriate adjustments to the above-mentioned embodiments, for example, reasonably select multiple correction angles to expand the set angle range as much as possible, the above-mentioned embodiments and the embodiments obtained by making appropriate adjustments to the above-mentioned embodiments are also embodiments of the present invention, and these implementations and other realizations are obvious to those skilled in the art and fall within the protection scope of the present invention.
In addition, for the extreme case that θ max exceeds the limit wind guiding angle θ of the first wind guiding assembly, the controller 16 may control the first wind guiding assembly to swing back and forth between its minimum wind guiding angle θ 1 and its maximum wind guiding angle θ 2, and it is also possible to refer to the above-mentioned embodiment, and it is obvious to those skilled in the art that these implementation manners and other realizable manners are within the protection scope of the present invention, as the angle range of θ 1 to (θ max - γ 1) or the angle range of (θ max1 + γ 1) to (θ max2 - γ 1) is taken as the set angle range according to the practical situation.
About the swing speed
When the controller 16 controls the first air guiding assembly to swing, the speed of homogenizing the spatial temperature distribution can be adjusted by controlling the swing speed in addition to selecting a reasonable set angle range, and when the swing is faster, the mixing of the air flow and the ambient air is easier to accelerate, so that the uniform spatial temperature distribution is accelerated. But at the same time, an increased swing speed also tends to improve the feel of the air and increase energy consumption.
Based on this, in some embodiments, the controller 16 is further configured to: determining that the indoor environment temperature is not in a comfortable temperature range, and taking a first swing speed as a designated swing speed; determining that the indoor environment temperature is in a comfortable temperature range, and taking a second swing speed as a designated swing speed, wherein the first swing speed is greater than or equal to the second swing speed; and controlling the first air guide assembly to swing at a designated swing speed within a set angle range. According to the analysis, when the indoor environment temperature is not in the comfortable temperature range, the requirement for accelerating the realization of the uniform distribution of the space temperature is stronger, so that the first swing speed is more than or equal to the second swing speed, the uniform distribution of the space temperature, the non-wind effect and the energy consumption can be balanced, and the optimization of the user experience comfort is facilitated.
the following detailed description is provided for the control of limiting the wind speed:
In some embodiments, the controller 16 is further configured to control at least one of the air guiding assembly 14 and the fan 12 to operate to make the wind speed of the outlet air of the air conditioner 1 greater than the non-wind-sensing wind speed when the air conditioner 1 is in the non-wind-sensing mode and the indoor ambient temperature is not within the comfortable temperature range, which helps to speed up the uniform distribution of the space temperature.
In some embodiments, the controller 16 is further configured to determine that the indoor environment temperature is within a comfortable temperature range when the air conditioner 1 is in the no-wind-sensation mode, and control at least one of the air guiding assembly 14 and the fan 12 to operate so that the wind speed of the outlet wind is less than or equal to the no-wind-sensation wind speed, so that the no-wind-sensation function can be satisfied when the requirement on the uniformity of the distribution of the air temperature is no longer strong, and the user experience comfort is improved.
specifically, by controlling the operation of the air guide assembly 14, the air outlet direction of the air conditioner 1 can be adjusted, and when the air outlet direction is closer to the normal direction of the plane where the indoor air outlet of the air conditioner 1 is located (hereinafter referred to as the normal direction of the indoor air outlet), the smaller the wind resistance is, the easier the air outlet flow is to be blown out to the front, and the higher the air outlet speed is. Besides the air outlet direction, the air outlet speed is also influenced by the rotating speed of the fan, and the higher the rotating speed of the fan is, the higher the air outlet speed is, so that the air outlet speed can be controlled by utilizing at least one of the air outlet direction and the rotating speed of the fan, namely, only the air outlet direction is regulated, or only the rotating speed of the fan is regulated, or the air outlet direction and the rotating speed of the fan are regulated simultaneously.
Control of air guide assembly 14 and fan 12
In some embodiments, the air deflection assembly 14 comprises a second air deflection assembly.
Furthermore, the second air guide assembly can be composed of a horizontal air guide plate extending along the horizontal direction, namely the horizontal air guide assembly, and the specific air outlet direction of the air flow in the vertical direction can be limited by controlling the second air guide assembly to rotate to a specific angle along the vertical direction. The second air guide assembly can also be composed of a vertical air guide plate extending along the vertical direction, namely the vertical air guide assembly, and the specific air outlet direction of the air flow in the left and right directions can be limited by controlling the second air guide assembly to rotate to a specific angle along the left and right directions. Of course, the second air guiding assembly may also be composed of air guiding plates extending along other directions, as long as the air outlet direction of the air conditioner 1 can be adjusted in a certain direction.
In some embodiments, the controller 16 is specifically configured to control the second wind guiding assembly to rotate and/or control the operation of the fan 12 to adjust the wind outlet speed. Specifically, the second air guide assembly is controlled to rotate to adjust the air outlet direction of the air conditioner 1, the power or the gear of the running of the fan 12 is controlled, the rotating speed of the fan is adjusted, and the air outlet speed of the air conditioner 1 can be adjusted by controlling at least one of the two. Further, the extending direction of the air guiding plate of the second air guiding assembly may be the same as or different from the extending direction of the air guiding plate of the first air guiding assembly in the foregoing embodiment, and when the extending directions are different, the extending directions may be orthogonal, for example, one horizontal and one vertical, and in this case, even if the air outlet direction corresponding to the second air guiding assembly is directed to the moving object region, the air flow may avoid the moving object region under the restriction of the first air guiding assembly. Furthermore, since the second air guiding assembly finally functions to change the wind speed of the outlet air, the air dispersing holes can be formed in the air guiding plate of the second air guiding assembly.
Further, the controller 16 is specifically configured to: controlling the second air guide assembly to rotate to a first air guide angle, and controlling the fan 12 to operate at a first rotating speed so that the air outlet speed is greater than the non-wind-sensing speed; and controlling the second air guide assembly to rotate to a second air guide angle, and controlling the fan 12 to operate at a second rotating speed so as to enable the air outlet speed to be less than or equal to the non-wind-sensing speed.
In some embodiments, when the air deflector of the second air guiding assembly extends in a vertical or approximately vertical direction, the air outlet direction corresponding to the first air guiding angle is closer to the normal direction of the indoor air outlet than the air outlet direction corresponding to the second air guiding angle; when the air deflector of the second air guiding assembly extends along the horizontal direction or the direction approximate to the horizontal direction, if the air conditioner 1 is in the cooling mode, the density of the blown cold air flow is high, and the air flow is easy to sink, at the moment, the air outlet direction is more upward, the air flow is easier to mix with the indoor air in the subsequent sinking process, and the uniform distribution of the space temperature can be promoted, otherwise, if the air conditioner 1 is in the heating mode, the air outlet direction is more downward, which is more favorable for promoting the uniform distribution of the space temperature, so the degree close to the normal direction of the indoor air outlet can be combined with the specific orientation in different operation modes, the air outlet direction corresponding to the first air guiding angle can be closer to the normal direction of the indoor air outlet than the air outlet direction corresponding to the second air guiding angle, the air outlet direction corresponding to the first air guiding angle can be upward in the cooling mode, and the air outlet direction corresponding to the first air, the second wind guide angle does not need to strictly limit the direction of the wind outlet direction corresponding to the second wind guide angle. Of course, the conditions of both aspects may also be satisfied by only one of them.
It can be imagined that if first wind-guiding angle too is close to indoor air outlet's normal direction, also cause the user uncomfortable easily, so can inject the difference of first wind-guiding angle and second wind-guiding angle in a reasonable scope, for example make the value range of the difference of first wind-guiding angle and second wind-guiding angle be 0 to 30, further can be 0 to 20.
The first rotating speed and the second rotating speed respectively correspond to a fan rotating speed, the first rotating speed is larger than the second rotating speed, and the air outlet speed corresponding to the first rotating speed is larger than the air outlet speed corresponding to the second rotating speed under the condition that the air guide angles are the same.
It can be understood that the above control conditions for the air outlet direction and the fan rotation speed may be satisfied simultaneously or only one of them, for example, only the condition for the air outlet direction is satisfied, and the second rotation speed is equal to or slightly greater than the first rotation speed, or vice versa, as long as the size relationship between the corresponding air outlet speed and the non-wind-sensing speed satisfies the requirement.
Relation of how to determine indoor environment temperature and comfortable temperature range
In some embodiments, the controller 16 specifically adopts a scheme of determining whether the difference between the indoor ambient temperature and the set temperature is smaller than a preset difference when determining whether the indoor ambient temperature is within the comfortable temperature range, that is, when the difference is smaller than the preset difference, the indoor ambient temperature is considered to be within the comfortable temperature range, and when the difference is greater than or equal to the preset difference, the indoor ambient temperature is considered not to be within the comfortable temperature range. Wherein the set temperature is a desired temperature set by the user on the air conditioner 1. When the refrigeration mode is operated, the difference value between the indoor environment temperature and the set temperature is the value obtained by subtracting the set temperature from the indoor environment temperature, and the comfortable temperature range is from minus infinity to the refrigeration preset temperature, wherein the refrigeration preset temperature is the sum of the set temperature and the preset difference value; when the heating mode is operated, the difference value between the indoor environment temperature and the set temperature is the difference value obtained by subtracting the indoor environment temperature from the set temperature, and the comfortable temperature range is from the heating preset temperature to plus infinity, wherein the heating preset temperature is the value obtained by subtracting the preset difference value from the set temperature. In other words, the difference between the indoor ambient temperature and the set temperature represents the gap that exists when the indoor ambient temperature is adjusted to the set temperature. The preset difference value represents that when the indoor environment is not in a comfortable state, the critical value of the difference is influenced by the set temperature and human feeling, an empirical value can be adopted, and different values can be obtained through experiments aiming at different set temperatures. If the difference is larger than or equal to the preset difference, the indoor environment does not reach a comfortable state, and the requirement on temperature regulation is stronger; if the difference is smaller than the preset difference, the indoor environment is comfortable, and the temperature regulation requirement is not strong any more.
Further, the value range of the preset difference is-5 ℃ to 5 ℃, and further can be-3 ℃ to 3 ℃. Since the indoor environment temperature is considered to be in the comfortable temperature range when the difference is smaller than the preset difference, when the preset difference is a positive value, the indoor environment temperature is considered to reach a comfortable state when the difference is still a certain distance from the set temperature, specifically, the indoor environment temperature is higher than the set temperature in the cooling operation mode, and the indoor environment temperature is lower than the set temperature in the heating operation mode; when the preset difference value is a negative value, it represents that the comfortable state is considered to be reached when the indoor environment temperature exceeds the set temperature to a certain degree, specifically, the preset temperature is lower in the cooling operation mode, and the preset temperature is higher in the heating operation mode. By changing the value of the preset difference value, the control of different strictness degrees can be realized. In addition, when the uniformity of the space temperature is poor, the detected indoor environment temperature may not be enough to reflect the indoor overall temperature condition, may be higher or lower, and at the moment, the setting position of the temperature sensor is combined, and the control accuracy can be improved by reasonably selecting the positive and negative of the preset difference value. For example, when the temperature sensor is disposed at a position close to the air outlet direction, the detected indoor environment temperature may be closer to the air outlet temperature and deviate from the temperatures of other indoor areas, so that the difference between the detected indoor environment temperature and the set temperature is small, and at this time, the preset difference may be set as a negative value; conversely, when the temperature sensor is disposed at a position away from the air outlet direction, particularly when the detected indoor ambient temperature is closer to the temperature of other indoor areas, the preset difference value may be set to a positive value.
In some embodiments, further, since there is a case where the user sets the set temperature unreasonably, the set temperature may be corrected by introducing a corrected temperature that conforms to the comfort of the human body, and the value of the set temperature may be replaced with the value of the corrected temperature to adjust the comfortable temperature range. It will be appreciated that the alternative modification of the set temperature is only used for adjusting the comfort temperature range and not for the tempering control of the air conditioner 1, i.e. the target temperature of the tempering process of the air conditioner 1 still corresponds to the value of the original set temperature. Further, the correction temperature may range from 15 ℃ to 32 ℃, and further from 17 ℃ to 30 ℃.
specifically, the controller 16 is further configured to: in a refrigeration mode, determining that the set temperature is greater than or equal to the correction temperature, and detecting the magnitude relation between the indoor environment temperature and the set temperature; and determining that the set temperature is less than the correction temperature, replacing the value of the set temperature with the value of the correction temperature, and detecting the magnitude relation between the indoor environment temperature and the set temperature.
The controller 16 is also configured to: under the heating mode, determining that the set temperature is less than or equal to the correction temperature, and detecting the magnitude relation between the indoor environment temperature and the set temperature; and determining that the set temperature is greater than the correction temperature, replacing the value of the set temperature with the value of the correction temperature, and detecting the magnitude relation between the indoor environment temperature and the set temperature.
In some embodiments, further, as the temperature adjusting process advances, the indoor environment temperature may gradually become comfortable, and to ensure timely understanding of the change of the indoor environment temperature for controlling the air guiding assembly 14 and/or the fan 12 accordingly, the controller 16 may detect whether the indoor environment temperature is within the comfortable temperature range every second preset time period in the no-wind mode. The second preset time period is related to the temperature regulation rate of the air conditioner 1, is particularly related to the initial environment temperature, the set temperature, the refrigerant, the system energy efficiency and the like, can be obtained through theoretical calculation, numerical simulation or experiments, and can be a fixed value for the determined air conditioner 1 or can be changed along with the difference between the initial environment temperature and the target temperature.
An embodiment of another aspect of the present invention provides a control method of an air conditioner. The air conditioner provided by any one of the above embodiments includes a fan and an air guide assembly, in addition to a compressor, a throttling device, an indoor heat exchanger and an outdoor heat exchanger, and details are not described herein.
Fig. 2 is a schematic flow chart of a control method of an air conditioner according to an embodiment of the present invention, and it should be noted that the flow is executed on the premise that the air conditioner is in a no-wind mode, and the flow is not shown in the figure. As shown in fig. 2, the control method of the air conditioner includes:
And S102, controlling the air guide assembly to operate so that the air flow from the air conditioner changes in a range avoiding a moving object area when the moving object exists in the target area, wherein the moving object area is the area where the moving object is located in the target area.
By controlling the operation of the air guide assembly, the air flow blown out from the air conditioner can be changed within the range of avoiding the moving object area, specifically, the change of the direction (namely the air outlet direction) of the air flow is realized, the non-wind-sensing effect and the uniformity of the spatial temperature distribution are considered, and the comfort of user experience is improved.
And S104, determining that the indoor environment temperature is not in the comfortable temperature range, and controlling at least one of the air guide assembly and the fan to operate so as to enable the air outlet speed of the air conditioner to be larger than the non-wind-sensing speed.
And S106, determining that the indoor environment temperature is in a comfortable temperature range, and controlling at least one of the air guide assembly and the fan to operate so as to enable the air outlet speed to be less than or equal to the non-wind-sensing speed.
in the two steps, the adjustment of the air outlet speed can be determined according to the relation between the indoor environment temperature and the comfortable temperature range, so that the requirement for accelerating the realization of the uniform distribution of the space temperature and the requirement for no wind sensation can be reasonably met. Particularly, through the operation of control wind guide assembly, the air-out direction of adjustable air conditioner, when the air-out direction was close to the normal direction of the indoor air outlet of air conditioner more, the windage just is littleer, and the air-out air current just blows off to the dead ahead more easily more, and the air-out wind speed is just also higher. Besides the air outlet direction, the air outlet speed is also influenced by the rotating speed of the fan, and the higher the rotating speed of the fan is, the higher the air outlet speed is, so that the air outlet speed can be controlled by utilizing at least one of the air outlet direction and the rotating speed of the fan, namely, only the air outlet direction is regulated, or only the rotating speed of the fan is regulated, or the air outlet direction and the rotating speed of the fan are regulated simultaneously.
The following is detailed with respect to S102 in fig. 2:
In some embodiments, the moving object may be a human or an animal to meet a variety of temperature regulation scenario requirements.
in some embodiments, to detect the moving object region, the air conditioner is further configured with a detector, which may be an infrared sensor or a radar sensor, or of course, the infrared sensor and the radar sensor may be provided at the same time to improve the accuracy of the detection, and other detectors having similar functions may be selected, which are not listed here.
Further, in order to realize the detection of the moving object, the air conditioner can also receive a detection result sent by the wearable device.
It is conceivable that, regardless of whether the detector or the wearable device is used, the detector or the wearable device may process the position information of the moving object first, and acquire and use the moving object region obtained after the processing, or may directly acquire the position information of the moving object detected by the detector or the wearable device and then calculate the moving object region. Of course, it is obvious to those skilled in the art that the air conditioner may also be equipped with the above detector and the ability to communicate with the wearable device to improve the flexibility and accuracy of the detection.
Furthermore, the moving object area is easy to change due to the high possibility of the position of the moving object changing, so that the moving object area can be acquired once every first preset time period, so as to adjust the operation of the air guide assembly accordingly. The first preset duration is an average duration expected to change the position of the mobile object, and may be obtained through statistics or set by a user.
In some embodiments, the air deflection assembly comprises a first air deflection assembly. The operation of controlling the operation of the air guide assembly can be specifically executed as: and controlling the first air guide assembly to swing within a set angle range. At this time, the direction of the air current flowing out of the air conditioner can be guided to change along with the swing of the first air guide assembly, and it can be understood that the set angle range corresponds to a range avoiding the moving object region.
Further, when the first air guiding assembly is controlled to swing within the set angle range, the following steps can be specifically executed: determining that the indoor environment temperature is not in a comfortable temperature range, and taking a first swing speed as a designated swing speed; determining that the indoor environment temperature is in a comfortable temperature range, and taking a second swing speed as a designated swing speed, wherein the first swing speed is greater than or equal to the second swing speed; and controlling the first air guide assembly to swing at a designated swing speed within a set angle range.
When the indoor environment temperature is not in the comfortable temperature range, the requirement for accelerating the realization of the uniform distribution of the space temperature is stronger. The speed of homogenizing the spatial temperature distribution can be adjusted by controlling the swinging speed of the first air guide assembly, and when the swinging speed is higher, the mixing of the air flow and the ambient air is easier to accelerate, so that the uniform spatial temperature distribution is accelerated. But at the same time, an increased swing speed also tends to improve the feel of the air and increase energy consumption. Therefore, the first swing speed is greater than or equal to the second swing speed, the space temperature uniform distribution performance, the no wind sensation effect and the energy consumption can be balanced, and the user experience comfort can be optimized.
FIG. 3 shows a schematic flow diagram of a process of determining a set angle range according to one embodiment of the present invention. As shown in fig. 3, the process includes:
S202, the moving object limit angle θ max is acquired, and the angular range from 0 to θ max is defined as the moving object region.
The position of the moving object is uniformly expressed by a position angle, the position angle adopts the same direction standard, for example, a reference ray is led along the surface of the air conditioner by taking the center of an air outlet in the air conditioner as a vertex, and a position ray is led through the vertex and the central point of the moving object, so that the included angle formed by the reference ray and the position ray is the position angle of the moving object, the number of the moving objects can be at least one, the obtained position angle is at least one, and the largest angle in the position angles is taken as the moving object limit angle theta max, so that the moving object area can be expressed in the angle range of 0 to theta max.
And S204, determining that the limit angle theta max of the moving object, the limit wind guide angle theta and the first correction angle gamma 1 meet the conditions that theta max is less than theta and (theta max + gamma 1) < theta, and taking an angle range from (theta max + gamma 1) to theta as a set angle range, wherein the limit wind guide angle theta is the maximum wind guide angle of the first wind guide assembly.
The air guide angle of the first air guide assembly is in the same angle rule with the position angle of the moving object, so that the air outlet direction of the air flow and the position of the moving object can be compared and controlled, when the air guide angle is between 0 and theta max, the air flow flowing out of the air conditioner can enter the moving object area, and when the air guide angle is between theta max and theta, the air flow can avoid the moving object area.
Further, the value range of the first correction angle γ 1 is 0 ° to 40 °, and further 0 ° to 30 °, and the final value thereof can be selected within the range according to the actual situation, and is pre-stored in the air conditioner, and the user can also be given the authority to set or modify the first correction angle γ 1.
s206, determining that the limit angle theta max of the moving object, the limit wind guide angle theta and the first correction angle gamma 1 meet the condition that theta max is not more than theta and (theta max + gamma 1) is not less than theta, and taking the angle range from theta max to theta as the set angle range.
In the case where (θ max + γ 1) ≧ θ, the angular range from (θ max + γ 1) to θ cannot be used as the set angular range, and the angular range from θ max to θ that avoids the movement target region can be directly used as the set angular range, and the spatial temperature distribution uniformity can be ensured without narrowing down the range.
In other embodiments, S206 may alternatively determine that the limit angle θ max of the moving object, the limit wind guiding angle θ, the first correction angle γ 1, and the second correction angle γ 2 satisfy the conditions that θ max < θ, (θ max + γ 1) ≧ θ and (θ max + γ 2) < θ, and the first correction angle γ 1 is greater than the second correction angle γ 2 with the angle range from (θ max + γ 2) to θ as the set angle range, that is, for the condition that (θ max + γ 1) ≧ θ, the second correction angle γ 2 smaller than the first correction angle γ 1 is further increased, and as long as (θ max + γ 2) < θ can be satisfied, the possibility of the air flow blowing the moving object directly is reduced as much as possible with the angle range from (θ max + γ 2) to θ as the set angle range.
further, the value range of the second correction angle γ 2 is 0 ° to 40 °, and further 0 ° to 20 °, similar to the first correction angle γ 1, the final value thereof may also be selected within the range according to the actual situation, and is prestored in the air conditioner, and the user may also be given the authority to set or modify the first correction angle γ 1 autonomously.
Of course, to improve the adaptability of the solution, it is obvious to those skilled in the art that multiple correction angles may be provided, and all of them fall into the protection scope of the present invention.
in addition, for the extreme case of θ max > θ, the first wind guiding assembly can be controlled to keep swinging back and forth within the swinging capability range, and also can be controlled to swing within the other side range of the air conditioner when the moving object area is concentrated on one side of the air conditioner, or to swing within the area in front of the air conditioner when the moving object is concentrated on two sides of the air conditioner and there is no moving object in the area in front of the air conditioner according to the actual distribution of the moving object area.
The following detailed description is made with respect to S104 and S106 in fig. 2:
in some embodiments, the air deflection assembly comprises a second air deflection assembly. The operation of controlling the operation of at least one of the air guide assembly and the fan may be specifically performed as: and controlling the second air guide assembly to rotate and/or controlling the fan to operate so as to adjust the air outlet speed. Specifically, the second air guide assembly is controlled to rotate the air outlet direction of the adjustable air conditioner, the running power or the running gear of the fan is controlled, the rotating speed of the fan can be adjusted, and the air outlet speed of the air conditioner can be adjusted by controlling at least one of the second air guide assembly and the fan. Further, the extending direction of the air guiding plate of the second air guiding assembly may be the same as or different from the extending direction of the air guiding plate of the first air guiding assembly in the foregoing embodiment, and when the extending directions are different, the extending directions may be orthogonal, for example, one horizontal and one vertical, and in this case, even if the air outlet direction corresponding to the second air guiding assembly is directed to the moving object region, the air flow may avoid the moving object region under the restriction of the first air guiding assembly.
Further, the operation of controlling the operation of at least one of the air guiding assembly and the fan may be further specifically performed as: controlling the second air guide assembly to rotate to a first air guide angle, and controlling the fan to operate at a first rotating speed so that the air outlet speed is greater than the non-wind-sensing speed; and controlling the second air guide assembly to rotate to a second air guide angle, and controlling the fan to operate at a second rotating speed so that the air outlet speed is less than or equal to the non-wind-sensing speed. The first air guide angle and the second air guide angle respectively correspond to the air outlet direction of an air conditioner, the first rotating speed and the second rotating speed respectively correspond to a fan rotating speed, for example, the air outlet direction corresponding to the first air guide angle is closer to the normal direction of the indoor air outlet than the air outlet direction corresponding to the second air guide angle, and meanwhile, the first rotating speed is greater than the second rotating speed, so that the air outlet speed corresponding to the first air guide angle and the first rotating speed can be ensured to be greater than the air outlet speed corresponding to the second air guide angle and the second rotating speed. Of course, the two conditions may also only satisfy one condition, for example, only the condition of the wind outlet direction is satisfied, and the second rotation speed is equal to or slightly greater than the first rotation speed, or vice versa, as long as the size relationship between the corresponding wind outlet speed and the wind-free speed satisfies the requirement.
It can be imagined that if first wind-guiding angle too is close to indoor air outlet's normal direction, also can cause the user uncomfortable, so can inject the difference of first wind-guiding angle and second wind-guiding angle in a reasonable scope, for example make the value range of the difference of first wind-guiding angle and second wind-guiding angle be 0 to 30, further can be 0 to 20.
in some embodiments, when detecting whether the indoor ambient temperature is within the comfortable temperature range, a scheme of determining whether a difference between the indoor ambient temperature and the set temperature is smaller than a preset difference is specifically adopted, that is, when the difference is smaller than the preset difference, the indoor ambient temperature is considered to be within the comfortable temperature range, and when the difference is greater than or equal to the preset difference, the indoor ambient temperature is considered not to be within the comfortable temperature range. Wherein the set temperature is a desired temperature set by a user on the air conditioner. When the refrigeration mode is operated, the difference value between the indoor environment temperature and the set temperature is the value obtained by subtracting the set temperature from the indoor environment temperature, and the comfortable temperature range is from minus infinity to the refrigeration preset temperature, wherein the refrigeration preset temperature is the sum of the set temperature and the preset difference value; when the heating mode is operated, the difference value between the indoor environment temperature and the set temperature is the difference value obtained by subtracting the indoor environment temperature from the set temperature, and the comfortable temperature range is from the heating preset temperature to plus infinity, wherein the heating preset temperature is the value obtained by subtracting the preset difference value from the set temperature. In other words, the difference between the indoor ambient temperature and the set temperature represents the gap that exists when the indoor ambient temperature is adjusted to the set temperature. The preset difference value represents that when the indoor environment is not in a comfortable state, the critical value of the difference is influenced by the set temperature and human feeling, an empirical value can be adopted, and different values can be obtained through experiments aiming at different set temperatures. If the difference is larger than or equal to the preset difference, the indoor environment does not reach a comfortable state, and the requirement on temperature regulation is stronger; if the difference is smaller than the preset difference, the indoor environment is comfortable, and the temperature regulation requirement is not strong any more.
Further, the value range of the preset difference is-5 ℃ to 5 ℃, and further can be-3 ℃ to 3 ℃. Since the indoor environment temperature is considered to be in the comfortable temperature range when the difference is smaller than the preset difference, when the preset difference is a positive value, the indoor environment temperature is considered to reach a comfortable state when the difference is still a certain distance from the set temperature, specifically, the indoor environment temperature is higher than the set temperature in the cooling operation mode, and the indoor environment temperature is lower than the set temperature in the heating operation mode; when the preset difference value is a negative value, it represents that the comfortable state is considered to be reached when the indoor environment temperature exceeds the set temperature to a certain degree, specifically, the preset temperature is lower in the cooling operation mode, and the preset temperature is higher in the heating operation mode. By changing the value of the preset difference value, the control of different strictness degrees can be realized. In addition, when the uniformity of the space temperature is poor, the detected indoor environment temperature may not be enough to reflect the indoor overall temperature condition, may be higher or lower, and at the moment, the setting position of the temperature sensor is combined, and the control accuracy can be improved by reasonably selecting the positive and negative of the preset difference value. For example, when the temperature sensor is disposed at a position close to the air outlet direction, the detected indoor environment temperature may be closer to the air outlet temperature and deviate from the temperatures of other indoor areas, so that the difference between the detected indoor environment temperature and the set temperature is small, and at this time, the preset difference may be set as a negative value; conversely, when the temperature sensor is disposed at a position away from the air outlet direction, particularly when the detected indoor ambient temperature is closer to the temperature of other indoor areas, the preset difference value may be set to a positive value.
In some embodiments, further, since there is a case where the user sets the set temperature unreasonably, the set temperature may be corrected by introducing a corrected temperature that conforms to the comfort of the human body, and the value of the set temperature may be replaced with the value of the corrected temperature to adjust the comfortable temperature range. It is understood that the alternative modification of the set temperature is only used for adjusting the comfortable temperature range and not for the temperature adjustment control of the air conditioner, i.e. the target temperature of the temperature adjustment process of the air conditioner still is based on the value of the original set temperature. Further, the correction temperature may range from 15 ℃ to 32 ℃, and further from 17 ℃ to 30 ℃.
Specifically, the correction process is performed as:
In a refrigeration mode, determining that the set temperature is greater than or equal to the correction temperature, and detecting the magnitude relation between the indoor environment temperature and the set temperature; and determining that the set temperature is less than the correction temperature, replacing the value of the set temperature with the value of the correction temperature, and detecting the magnitude relation between the indoor environment temperature and the set temperature.
Under the heating mode, determining that the set temperature is less than or equal to the correction temperature, and detecting the magnitude relation between the indoor environment temperature and the set temperature; and determining that the set temperature is greater than the correction temperature, replacing the value of the set temperature with the value of the correction temperature, and detecting the magnitude relation between the indoor environment temperature and the set temperature.
In some embodiments, further, as the temperature adjusting process advances, the indoor ambient temperature may gradually become comfortable, and to ensure that the change condition of the indoor ambient temperature is known in time so as to control the air guide assembly and/or the fan accordingly, it may be detected whether the indoor ambient temperature is within the comfortable temperature range every second preset time period in the no-wind-sense mode. The second preset time is related to the temperature regulation rate of the air conditioner, is particularly related to the initial environment temperature, the set temperature, the refrigerant, the system energy efficiency and the like, can be obtained through theoretical calculation, numerical simulation or experiments, and can be a fixed value for the determined air conditioner or can change along with the difference between the initial environment temperature and the target temperature.
Next, two specific embodiments of the control method of the air conditioner according to the present invention will be described.
Detailed description of the preferred embodiment

The air guide assembly of the air conditioner comprises a first air guide assembly and a second air guide assembly, the first air guide assembly is a horizontal air guide assembly capable of swinging up and down and comprises at least one horizontal air guide plate, and the second air guide assembly is a vertical air guide assembly capable of swinging left and right and comprises at least one vertical air guide plate. Fig. 5 shows the wind guiding angle of the vertical wind guiding assembly from a top view, and fig. 6 shows the wind guiding angle of the horizontal wind guiding assembly from a side view. The air conditioner operates in a cooling mode. The operation of the air conditioner is divided into the following five steps, each step corresponding to one row of contents in fig. 4:
The method comprises the following steps: a user sets a no-wind mode;
