Description

Technical Field

[0001] The present application relates to the technical field of refrigeration equipment, and in particular to a collaborative control method for dual air guide plates, an indoor unit, and a heat pump air conditioner. Background Art

[0002] Wind sensation is an important indicator of customer experience when a heat pump air conditioner is in operation, and there are also higher requirements for the comfort and diversity of its air supply.

[0003] Prior art (CN110285548A) discloses an air supply control method and air conditioner indoor unit. The method describes an air guide plate installed at the air outlet of the air conditioner indoor unit. The plate can swing up and down to direct airflow in multiple directions, and the swing angle range of the plate is divided into multiple angular zones. The air supply control method includes: during the process of the air guide plate swinging from closed to open, when the air guide plate swings within any angular zone, controlling the average air volume discharged from the air outlet to be less than the average air volume discharged from the air outlet when the air guide plate swings within the previous angular zone. This method solves the problem of rapid heating and cooling in air conditioners.

[0004] However, in actual application, air conditioners with a single air guide plate have a limited air supply angle, which restricts the adjustment of the air supply direction and causes uneven air distribution, resulting in differences in cold and warm areas in the room. Summary of the Invention

[0005] In order to improve the uniformity of air output from air conditioners and reduce the difference between cold and warm areas in a room, the present application provides a collaborative control method for dual air guide plates, an indoor unit, and a heat pump air conditioner.

[0006] In a first aspect, the present application provides a collaborative control method for dual air guide plates, which adopts the following technical solution: A collaborative control method for dual air guide plates includes the following steps: S1: Monitor the target location through radar and upload the monitoring information to the cloud; S2: obtaining input information of the driving device according to the monitoring information of the radar, and calculating and obtaining output information of the driving device based on the input information of the driving device; S3: Based on the radar monitoring information, the radar area is divided into regional modules and the air conditioning mode is triggered; S4: Control the air-conditioning swing according to the air-conditioning mode; Among them, the air-conditioning swing is controlled by the driving device, and the driving device includes a first air guide plate, a second air guide plate, a first driving member and a second driving member. The first driving member and the second driving member control the angle of the rotating shaft through a pulse signal. The first driving member controls the rotation of the first air guide plate, and the second driving member controls the rotation of the second air guide plate.

[0007] By adopting the above technical solution, the target position is monitored by radar and the information is uploaded to the cloud, which improves the accuracy and real-time performance of monitoring and provides data support for subsequent intelligent control. Based on the radar monitoring information, the input and output information of the drive device is obtained and calculated to ensure the precise control of the air-conditioning swing. According to the radar monitoring information, the modules are divided within the radar area and the corresponding air-conditioning modes are triggered to achieve adaptive adjustment of the air-conditioning system. This intelligent triggering mechanism enables the air-conditioning system to better meet the actual needs of users.

[0008] The present invention can control the coordinated rotation of the first and second air deflectors by a drive device, or can drive the first and second air deflectors to rotate independently to achieve a set angle. The dual air deflectors of the present invention can evenly distribute air to every corner of the room, reducing the difference between cold and warm areas, making the air flow smoother, and have an adjustable wind direction function. The user can adjust the wind direction as needed, which can effectively meet the user's personal preference for wind feeling.

[0009] Preferably, in the process of the driving device controlling the swing of the air conditioner, the second air guide plate cooperates with the movement of the first air guide plate. The specific steps are: when the air conditioner is started, the second driving member controls the second air guide plate to move first, providing concession space for the first air guide plate; when the air conditioner is turned off, the first driving member controls the first air guide plate to move first, and the second air guide plate then cooperates with the movement; ensuring that the first air guide plate and the second air guide plate do not interfere with each other.

[0010] By adopting the above technical solution, the spatial layout between the driving device and the first air guide plate and the second air guide plate is creatively set, and the starting sequence of the three is creatively set, so that the two air guide plates can coordinately control the rotation sequence and the different rotation angles, which can effectively prevent the two air guide plates from colliding and interfering with each other, so that the air conditioner can achieve the purpose of low cost and safe operation, and the air conditioner can create a smarter and more comfortable experience for users.

[0011] Preferably, the premise for triggering the air-conditioning mode is: receiving a signal instruction from an APP or a remote control; the signal instruction includes a wind-following mode, a wind-avoiding mode, and an energy-saving mode.

[0012] By adopting the above technical solutions, users are provided with a variety of personalized air-conditioning control options, which improves the convenience and comfort of use.

[0013] Preferably, after radar monitoring, the number of targets, target angle, target distance and target movement speed are calculated and acquired, and the monitoring information is converted into input information for the driving device. The driving device includes a control unit, and the control unit is used to acquire input information and calculate output information, specifically including: 1) Based on the number of targets, target angle, target distance and target movement speed obtained by the control unit, the left and right wind sweep angles are calculated ; 2) Based on the target angle obtained by the control unit, calculate the upper and lower sweep angles .

[0014] By adopting the above technical solution, radar monitoring can accurately obtain key information such as the number of targets, target angle, target distance and target movement speed in real time. This information provides data support for the control of the air conditioner, ensuring the accuracy and real-time performance of the air conditioning swing. The control unit can quickly calculate the left and right sweep angles and the up and down sweep angles based on the radar monitoring information, thereby achieving precise control of the air conditioning swing.

[0015] By dynamically adjusting the air sweep angle according to the target number and position, the air conditioning system can provide users with a more personalized air supply experience, achieve uniform air supply in multi-person scenarios, and achieve directional air supply in single-person scenarios, thereby meeting the needs of different users.

[0016] Preferably, the first driving member and the second driving member are both stepper motors. By installing encoders at the ends of the first driving member and the second driving member respectively, the PLC sends a synchronization pulse signal to start the first driving member and the second driving member, and the encoder feeds back the position. The position deviation is compared with the size of the threshold to determine whether the position deviation is greater than the threshold. If so, the pulse compensation is adjusted. If not, the synchronous operation continues.

[0017] By adopting the above technical solution, using stepper motors as the first and second drive elements, combined with encoder feedback position information, precise control of the position of the dual air guide plates is achieved, which helps to reduce position deviation. A synchronous pulse signal is sent through the PLC to start the first and second drive elements to ensure the coordinated movement of the dual air guide plates, thereby effectively reducing the motion interference between the air guide plates and improving the overall performance and response speed of the air-conditioning system.

[0018] Preferably, in the step of dividing the radar area into area modules, Based on the number of targets, target angle, target distance and target movement speed, the radar radiation area is divided into N areas vertically and M areas horizontally, forming N×M sweeping wind areas. Adjacent sweeping wind areas overlap by 5°-10° to ensure that there are no blind spots in radar monitoring. Based on the number of targets and target movement speed, the border area boundaries are dynamically adjusted, and the dynamic information is synchronously uploaded to the cloud.

[0019] By adopting the above technical solution, the radar radiation area is finely divided into N×M wind sweeping areas based on the number of targets, target angle, target distance and target movement speed, ensuring blind-spot coverage of radar monitoring. This division method can improve the targeting and accuracy of the air-conditioning swing, and provide users with a more personalized air supply experience; the boundary of the side area is dynamically adjusted according to the number of targets and target movement speed, and the dynamic information is synchronously uploaded to the cloud, which can provide data support for subsequent data analysis and system upgrades.

[0020] Preferably, the air conditioning mode includes cooling mode, heating mode, maximum wind mode and light wind mode, specifically including: 1) Based on the wind-following-people mode, the cooling mode, the heating mode, the maximum wind sensing mode, or the light wind sensing mode is driven in combination; 2) driving in combination with the cooling mode, the heating mode, the maximum wind sensing mode, or the light wind sensing mode based on the wind avoidance mode; 3) Based on the energy-saving mode, the cooling mode, the heating mode, the maximum wind sensing mode, or the light wind sensing mode is immediately turned off or activated.

[0021] By adopting this technical solution, the air conditioning system can intelligently coordinate different driving modes based on user needs and environmental conditions. In Wind Follows Person mode, the air conditioner can adjust the air direction and air volume according to the user's movement, ensuring a comfortable environment at all times; in Wind Avoids Person mode, the air conditioner avoids blowing directly at the user, reducing user discomfort.

[0022] Preferably, according to the monitoring information of the radar, based on the wind-follows-people mode or the wind-avoids-people mode, the target position is dynamically locked, the wind sweeping area where the target is located is calculated, and the target wind sweeping area is obtained; in the wind-follows-people mode, the driving device controls the air-conditioning swing to follow the target wind sweeping area; in the wind-avoids-people mode, the driving device controls the air-conditioning swing to avoid the target wind sweeping area.

[0023] By adopting the above technical solution, the air-conditioning system can dynamically lock the target position in real time through radar monitoring information, and calculate the wind sweeping area where the target is located. In the wind-following-people mode, the air-conditioning swing wind can accurately follow the target wind sweeping area, ensuring that the user can feel a comfortable wind direction and air volume no matter where they move; in the wind-avoiding-people mode, the air-conditioning system can control the wind swing wind to avoid the target wind sweeping area, reducing the discomfort caused by direct blowing towards the user, thereby improving the user experience and making the air-conditioning more humane.

[0024] In a second aspect, the present application provides an indoor unit, comprising a driving device, wherein the driving device is applied to the collaborative control method of the dual air guide plates.

[0025] In a third aspect, the present application provides a heat pump air conditioner having the indoor unit described above.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1.

[0033] The following is combined with Figure 1-5 This application is described in further detail.

[0034] In a first aspect, an embodiment of the present application discloses a collaborative control method for dual air guide plates.

[0035] Reference Figure 1 A collaborative control method for dual air guide plates includes the following steps: The target position is monitored by radar, and the monitoring information is uploaded to the cloud. According to the radar monitoring information, the input information of the driving device is obtained, and based on the input information of the driving device, the output information of the driving device is calculated.

[0036] Radar monitoring information parameters include target number N, target angle or , target distance R, target movement speed v, and convert the monitoring information into input information for the driving device. The input information parameters specifically include the left and right wind sweep angles , Up and down wind sweep angle , internal fan speed S, temperature compensation value ΔT, in the present application, the driving device includes a control unit, and the control unit is used to obtain input information and calculate output information.

[0037] (1) Based on the target number N and target angle obtained by the control unit or , target distance R and target speed v, calculate the left and right wind sweep angles .

[0038] Specifically, when the target number N=1, the formula Calculate, where is the target azimuth detected by the radar, is the mechanical transmission coefficient determined by the gear ratio, 0.8≤ ≤1.2, It is the installation offset angle between the air conditioner and the wall.

[0039] When there are multiple targets, that is, the number of targets N>2, the priority target is the high-speed target, through the formula , Calculate, where Indicates the speed value of the i-th target detected by the radar, Indicates the maximum recognizable speed of radar monitoring. represents the target distance of the i-th target, Represents the original azimuth of the i-th target detected by the radar.

[0040] (2) Based on the target angle obtained by the control unit, calculate the upper and lower sweep angles .

[0041] Specifically, through the formula ), where L is the maximum air supply distance of the air conditioner, p is the thickness of the air conditioner body, z is the installation height of the air conditioner, and h is the target height detected by the radar.

[0042] (3) Based on the target number and target movement speed obtained by the control unit, the internal fan speed S is calculated, that is, the speed of the main wind motor that drives the air conditioner cover to rotate.

[0043] Specifically, through the formula ,in, is the basic speed of the motor, is the target per capita wind volume coefficient, is the distance attenuation compensation coefficient, It is a dynamic response gain and requires that high-speed targets need to increase wind speed. It takes effect when v>1m / s.

[0044] (4) Based on the number of targets and the target movement speed obtained by the control unit, the temperature compensation value ΔT is calculated.

[0045] By formula ,in, Indicates the ambient temperature which is the difference between the set temperature and the current temperature. Indicates thermal efficiency, 0.7≤ ≤0.9, Indicates the heating efficiency, is the specific heat capacity of air, represents the air mass flow rate, Indicates thermal delay compensation for moving targets, and requires that high-speed, near and far targets be heated in advance.

[0046] Based on the radar's monitoring information, the radar area is divided into regional modules and the air conditioning mode is triggered.

[0047] The radar module converts monitoring information into input for the driver. Receiving a signal from the app or remote control triggers the air conditioning mode; these signals include wind-following mode, wind-avoiding mode, and energy-saving mode. The driver then controls the air conditioning's swing mode based on the air conditioning mode, which includes cooling, heating, maximum wind, and light wind.

[0048] According to the monitoring information of the radar, based on the wind-following-people mode or the wind-avoiding-people mode, the target position is dynamically locked, the wind sweeping area where the target is located is calculated, and the target wind sweeping area is obtained; in the wind-following-people mode, the driving device controls the air conditioner to swing to follow the target wind sweeping area; in the wind-avoiding-people mode, the driving device controls the air conditioner to swing to avoid the target wind sweeping area.

[0049] Specifically, based on the target number N, target angle or , target distance R, target speed v, the space of the radar radiation area is divided into N areas in the vertical direction and M areas in the horizontal direction, forming N×M wind sweeping areas. Figure 5The demonstration shows that the wind sweeping area is divided into nine sectors by the radar radiation range to achieve accurate target positioning, air supply direction and energy-saving control.

[0050] Adjacent sweeping wind areas overlap by 5°-10° to ensure that there are no blind spots in radar monitoring. At the same time, the boundary of the side area is dynamically adjusted based on the number of targets and the target movement speed. When the target moves to the edge area, the radar module rotates the normal of the sensing area to generate a new symmetrical area. According to the distribution of the sweeping wind area, the cloud triggers the corresponding radar module nearby, and the radar module monitors the targets in the locked area in real time.

[0051] During the real-time monitoring of the targets in the locked area by the radar module, the number of targets N is determined first. When the number of targets is greater than or equal to two, the target distance R and target angle are calculated. or , and target movement speed v; when the target number is one person, first determine whether the target subject is a familiar subject. If so, based on the familiar subject's habitual position, the air conditioner is started first according to the parameters that have been used the most times in the past. If not, calculate and obtain the target distance R and target angle or , and target motion speed v.

[0052] The process of the driving device controlling the air swing of the air conditioner is specifically as follows: the driving device includes a first air guide plate 1, a second air guide plate 2, a first driving member and a second driving member. The first driving member and the second driving member control the angle of the rotating shaft through a pulse signal. The first driving member controls the rotation of the first air guide plate 1, and the second driving member controls the rotation of the second air guide plate 2.

[0053] The first driving member and the second driving member are both stepper motors. By installing encoders at the ends of the first driving member and the second driving member respectively, the PLC sends a synchronous pulse signal to start the first driving member and the second driving member, and the encoder feeds back the position. The position deviation is compared with the threshold to determine whether the position deviation is greater than the threshold. If so, the pulse compensation is adjusted. If not, the synchronous operation continues.

[0054] In the present application, the installation method and driving principle of the first air guide plate 1 and the second air guide plate 2 are the same. Taking the drive of the first air guide plate 1 as an example, the driving device also includes a drive box, a rotating shaft, and a connecting rod assembly. The connecting rod assembly can be slidably arranged in the drive box, and its tail end is connected to the first driving member through a gear rack transmission mechanism, and the head end of the connecting rod assembly is connected to the first air guide plate 1.

[0055] In the process of the driving device controlling the air swing of the air conditioner, the second air guide plate 2 cooperates with the movement of the first air guide plate 1. The specific steps are: when the air conditioner is started, the second driving component controls the second air guide plate 2 to move first, providing concession space for the first air guide plate 1; when the air conditioner is turned off, the first driving component controls the first air guide plate 1 to move first, and the second air guide plate 2 then cooperates with the movement; ensure that the first air guide plate 1 and the second air guide plate 2 do not interfere with each other.

[0056] In this application, the cooling mode or heating mode or maximum wind sensing mode or light wind sensing mode is coordinated and driven based on the wind follows people mode; the cooling mode or heating mode or maximum wind sensing mode or light wind sensing mode is coordinated and driven based on the wind avoidance people mode; the cooling mode or heating mode or maximum wind sensing mode or light wind sensing mode is instantly shut down or driven based on the energy-saving mode.

[0057] Specific examples are, for example, Figure 1 When the default cooling mode is on, the second air guide plate 2 rotates to 32° first, and then the first air guide plate 1 rotates to 116°, and the air flow blows upward. When the sweeping air is turned on, the second air guide plate 2 rotates from 32° to 90°, and the first air guide plate 1 rotates from 116° to 0°, and then rotates back in the opposite direction. Figure 2 In cooling mode, the second air guide plate 2 first rotates to 15 degrees, and the first air guide plate 1 then rotates to 60 degrees, causing the airflow to blow upward. Taking advantage of the higher density of cold air than the hot air in the room, the cold air slowly sinks under the action of gravity, while the hot air naturally rises. The cold air and hot air mix, forming a circulating convection system. This circulation method can evenly distribute the cold air throughout the room, thereby achieving a better cooling effect. At the same time, it can prevent the cold air from blowing directly on the user's body, reducing the discomfort caused by the sudden drop in temperature.

[0058] like Figure 3 In heating mode, the second air deflector 2 rotates to 90°, and the first air deflector 1 rotates to 0°, causing the airflow to blow downward. Similarly, because hot air is less dense than cold air, it naturally rises to the top of the room, while cold air sinks to the bottom. This allows the hot air to reach the user's active area, preventing discomfort. The air conditioner compressor doesn't need to work at high loads for extended periods to combat the stratification of hot and cold air in the environment, which helps save energy and electricity.

[0059] like Figure 4 When the light breeze mode is activated, the second air deflector 2 first rotates to 15°, and the first air deflector 1 then rotates to 30°, causing the airflow to blow upward. Upon power-on reset, the second air deflector 2 rotates 125° toward the structural limit, and then the first air deflector 1 rotates 125° toward the structural limit, i.e., the zero point. The second air deflector 2 then rotates to the 0° position, resting on the first air deflector 1.

[0060] When the dual air guide plates of the present invention are working, synchronous or coordinated movement can be achieved through a driving device, and the driving device controls the coordinated rotation of the first air guide plate 1 and the second air guide plate 2, or the driving device drives the first air guide plate 1 and the second air guide plate 2 to rotate separately to adjust the set angle. The dual air guide plates of the present invention can evenly distribute air to every corner of the room, reduce the difference between cold and warm areas, make the air flow smoother, and have the function of adjusting the wind direction. The user can adjust the wind direction as needed, which can effectively meet the user's personal preference for wind feeling. In addition, the two air guide plates coordinately control the rotation sequence and the difference in rotation angles, which can effectively prevent the two air guide plates from colliding and interfering with each other.

[0061] Compared with the existing technology, the shortcomings of uneven air distribution or limited wind direction adjustment in air conditioners with a single air guide plate can be well solved. This application creatively arranges the spatial layout between the driving device and the first air guide plate 1 and the second air guide plate 2, and sets the starting sequence of the three, so that the air conditioner can achieve low-cost and safe operation, and create a smarter and more comfortable experience for users.

[0062] In a second aspect, an indoor unit is disclosed, including a driving device, which is applied to a coordinated control method of double air guide plates.

[0063] In a third aspect, a heat pump air conditioner is disclosed. The heat pump air conditioner includes an indoor unit.

[0064] The above are all preferred embodiments of the present application. These embodiments are only explanations of the present application and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be covered within the scope of protection of the present application.
