[0021] In order to make the objects, technical solutions and advantages of the present application clearer, the technical solutions in the present application will be described clearly and completely below with reference to the drawings in the present application. Obviously, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0022] The control method of the indoor unit of the air conditioner will be described below. Figures 1-2 The control method of the indoor unit of the air conditioner will be described below.

[0023] Embodiments of the present application provide a control method of an indoor unit of an air conditioner, as shown in the figure, the control method comprises the following steps: Figure 1 Step 100, obtaining a current wind pressure signal corresponding to a current position of a guide vane.

[0024] It can be understood that the current air supply state of the guide vane is obtained by real-time acquisition of the current position of the guide vane and the current wind pressure signal corresponding to the current position.

[0025] Step 200, in the case that the current wind pressure signal is not within the threshold range, reducing the running rate of the guide vane and controlling the guide vane to rotate from the current position to a next position.

[0026] Wherein, one of the next wind pressure signal corresponding to the next position of the guide vane and the current wind pressure signal is positive, and the other is negative.

[0027] It can be understood that if it is detected that the current wind pressure signal exceeds the preset threshold range, it is judged that there is resistance in the air outlet of the guide vane at this time, the running rate of the guide vane is reduced, and the guide vane is controlled to rotate from the current position to the next position. The next wind pressure signal corresponding to the next position of the guide vane and the current wind pressure signal corresponding to the current position are respectively in positive pressure and negative pressure state, so as to realize the adjustment of the position of the guide vane.

[0028] Step 300, determining a target position of the guide vane based on the comparison result of the next wind pressure signal and the threshold range.

[0029] ​It can be understood that according to the comparison result of the next wind pressure signal fed back after the deflector reaches the next position and the threshold range, the target position of the deflector is further determined and optimized, so that the air outlet angle is optimized, the wind resistance is reduced, and the refrigeration or heating efficiency of the air conditioning system is improved.

[0030] The control method of the indoor unit of the air conditioner provided by the embodiment of the application can obtain the current wind pressure signal of the deflector in real time, determine whether the current wind pressure signal is within the threshold range, reduce the operating speed of the deflector when it is detected that the wind pressure signal is not within the threshold range, adjust the deflector to rotate from the current position to the next position, thereby changing the air outlet angle, obtain the corresponding wind pressure signal again after the deflector reaches the next position, and determine the optimal stopping position of the deflector in combination with the comparison result with the threshold range, thereby realizing the adjustment of the position of the deflector, effectively reducing the air outlet resistance, and improving the refrigeration or heating performance of the air conditioning system.

[0031] Optionally, as shown in FIG. 3, the step 300 can specifically include the following steps: Figure 2 The step 310 can determine the next position as the target position of the deflector when the comparison result is that the next wind pressure signal is within the threshold range.

[0032] It can be understood that after the deflector rotates from the current position to the next position, the next wind pressure signal corresponding to the next position is obtained and compared with the preset threshold range; if it is determined that the next wind pressure signal is within the threshold range and the deflector is at an air outlet angle with small wind resistance, it indicates that the current air outlet state is relatively ideal, and at this time, the next position is determined as the target position of the deflector, so that the deflector can stably blow air at this angle, thereby realizing the optimized control of the air outlet resistance and improving the air blowing efficiency and overall performance of the air conditioning system.

[0033] Optionally, the step 300 can specifically include the following steps: The step 320 can reduce the operating speed of the deflector again until the wind pressure signal of the adjusted deflector meets the threshold range when the comparison result is that the next wind pressure signal is not within the threshold range, and the adjusted position of the deflector is taken as the target position.

[0034] ​It can be understood that after the deflector is rotated from the current position to the next position, the next wind pressure signal corresponding to the next position is acquired and compared with the preset threshold range; if it is judged that the next wind pressure signal still exceeds the preset threshold range, it indicates that the current position of the deflector has not reached the ideal air supply state, and the rotation speed of the deflector will be continuously reduced to make the deflector continue to rotate to the next position, and the wind pressure change is monitored in real time after each adjustment. The process will continue until the wind pressure signal of the deflector after adjustment is detected to fall within the preset threshold range. At this time, the adjusted position is determined as the target position of the deflector, so as to realize dynamic optimization of the air outlet resistance and ensure that the air conditioning system works in the best operating state.

[0035] It should be noted that the change of the wind pressure signal of the deflector is monitored in real time during the rotation of the deflector from the current position to the next position; wherein the wind pressure signals corresponding to the current position and the next position are in opposite states, for example: if the wind pressure signal of the current position is positive pressure, the wind pressure signal of the next position is negative pressure; if it is continuously adjusted to the next position, the wind pressure signal will return to positive pressure, so that the wind pressure signal alternately changes between positive pressure and negative pressure during the adjustment of the deflector, so as to realize dynamic regulation of the air outlet resistance of the deflector, so as to improve the air supply efficiency and overall performance of the air conditioning system.

[0036] For example, step 200 can specifically include the following contents: In the case that the current wind pressure signal is positive, the rotation speed of the deflector is reduced, and the air outlet angle of the deflector is opened to control the deflector to rotate from the current position to the next position; In the case that the current wind pressure signal is negative, the rotation speed of the deflector is reduced, and the air outlet angle of the deflector is closed to control the deflector to rotate from the current position to the next position.

[0037] It can be understood that when it is detected that the current wind pressure signal is positive pressure, it indicates that the air outlet resistance is large at this time, the rotation speed of the deflector is reduced, the air outlet angle of the deflector is opened, the deflector is rotated from the current position to the next position, so as to change the air outlet direction and relieve the wind pressure.

[0038] When the current wind pressure signal is detected to be negative pressure, it indicates that there is abnormal suction in the air inlet or air supply path, the rotation speed of the deflector is reduced, the air outlet angle of the deflector is closed, the deflector is rotated from the current position to the next position, so as to change the air outlet direction and relieve the wind pressure.

[0039] According to the embodiment of the application, in step 200, the rotation speed of the deflector is reduced based on the last rotation speed of the deflector.

[0040] Optionally, when the air deflector is first controlled to rotate, the air deflector can be rotated at a preset rotation rate.

[0041] In one embodiment of the present application, the control method of the indoor unit of the air conditioner comprises the following steps: S1, initial state, the air deflector is opened to a certain air outlet angle, at this time, the air deflector is in an initial position, and an initial air pressure signal corresponding to the initial position of the air deflector is obtained; S2, it is judged whether the initial air pressure signal is in a threshold range; if not, step S3 is executed; S3, the air deflector is rotated from the initial position to a first position at a preset rotation rate, and a first air pressure signal corresponding to the first position and the initial air pressure signal corresponding to the initial position are in opposite states; S4, it is judged whether the first air pressure signal is in the threshold range; if not, step S5 is executed; S5, the rotation rate of the air deflector is reduced from the preset rotation rate to a first rotation rate, and the air deflector is rotated from the first position to a second position, and a second air pressure signal corresponding to the second position and the first air pressure signal corresponding to the first position are in opposite states; S6, based on the principles of step S4 and step S5, the rotation rate of the air deflector is continuously reduced until the adjusted air pressure signal meets the threshold range, and the adjusted air deflector position is taken as a target position.

[0042] It should be noted that when the air pressure signal of the air deflector is in the threshold range, the corresponding air deflector position is taken as the target position of the air deflector.

[0043] In this embodiment, the control method of the indoor unit of the air conditioner is as follows: In the initial state, the air deflector is opened to a certain air outlet angle, at this time, the air deflector is in an initial position, and after the air conditioning system is operated for 1 min, an initial air pressure signal corresponding to the initial position of the air deflector is obtained; In the case that the initial air pressure signal is not in the threshold range, when the initial air pressure signal is positive, the air deflector is operated downward at a preset rotation rate to open the air outlet angle of the air deflector; After the air deflector passes through the position of minimum air resistance to reach a first position, a first air pressure signal corresponding to the first position is negative, and it is judged whether the first air pressure signal is in the threshold range; In the case that the first air pressure signal is not in the threshold range, the rotation rate of the air deflector is reduced from the preset rotation rate to a first rotation rate, the first rotation rate is 1 / 2 of the preset rotation rate, and the air deflector is operated upward at the first rotation rate to close the air outlet angle of the air deflector; After the air deflector passes through the position of minimum air resistance again to reach a second position, a second air pressure signal corresponding to the second position is positive, and it is judged whether the second air pressure signal is in the threshold range; If the second wind pressure signal is not within the threshold range, the operating speed of the air deflector is reduced from the first operating speed to a second operating speed, the second operating speed being 1 / 2 of the first operating speed, and the air deflector is operated downward at the second operating speed to increase the air outlet angle of the air deflector. The above steps are repeated to continuously reduce the operating speed of the air deflector until the adjusted wind pressure is within ±10 pa, and the adjusted air deflector position is taken as the target position to keep the air deflector position fixed.

[0044] In an embodiment of the present application, step 100 can specifically include the following contents: If the operating time exceeds the preset time length, the current wind pressure signal corresponding to the current position of the air deflector is obtained.

[0045] It can be understood that during the startup operation, the fan has a process of increasing the speed from 0. After the air conditioner is started and continuously operated for a period of time, when it is judged that the operating time has exceeded the preset time length (for example, set to 3 minutes or a time threshold dynamically adjusted according to the actual operation condition), it is considered that the fan speed and the wind pressure have reached a stable state, and thus the detection phase of the air deflector control logic is entered, and the wind pressure signal corresponding to the current position of the air deflector is collected as a basis for judging whether the current air outlet state is normal.

[0046] In an embodiment of the present application, step 100 can specifically include the following contents: The speed variation of the fan is obtained. If the speed variation is greater than the preset variation, the current wind pressure signal corresponding to the current position of the air deflector is obtained.

[0047] It can be understood that the operating state of the fan is monitored in real time, the speed variation (air volume) of the current fan is obtained, and it is compared with the preset variation threshold. When it is detected that the speed variation of the fan exceeds the preset variation, it is considered that the current air supply state fluctuates greatly, and the position of the air deflector needs to be adjusted.

[0048] In the present embodiment, when the speed variation of the fan exceeds 30 revolutions, it is considered that the minimum resistance position of the air deflector changes, and the position of the air deflector needs to be adjusted to find the minimum resistance position again.

[0049] It should be noted that in the prior art, the opening and closing angle of the air guide plate is usually driven by a stepper motor and adjusted according to a plurality of preset gears, such as the common five-gear adjustment method: lower air outlet, middle lower air outlet, middle air outlet, middle upper air outlet and upper air outlet. The wind speed of the fan is usually divided into 5 gears, namely low wind, middle low wind, middle wind, middle high wind and high wind; or the wind speed of the fan is divided into 3 gears, namely low wind, middle wind and high wind. The wind speed gear and the opening and closing angle of the air guide plate are controlled separately, and the two cannot be linked, resulting in the following problem: when the user wants to ensure high energy efficiency operation, for example, the wind speed is at a high wind gear, but the opening and closing angle of the air guide plate is not the position with the largest air volume, such as the upper air outlet angle, then unnecessary air outlet resistance will be generated, resulting in unnecessary energy consumption, and then resulting in a loss of cooling / heating capacity. In the embodiment of the present invention, when the air volume of the fan changes, the operating speed of the air guide plate is reduced based on the wind pressure signal of the air guide plate to adjust the air outlet angle of the air guide plate to minimize wind resistance, thereby improving the cooling or heating performance of the air conditioning system.

[0050] It should be noted that in the prior art, when the fan speed is different, the position of the air deflector with the minimum wind resistance is also different. For example, the minimum wind resistance position (maximum air volume position) corresponding to a fan speed of 600 is different from the minimum wind resistance position corresponding to a fan speed of 1200. The minimum wind resistance position corresponding to a speed of 1200 during heating is also different from the minimum wind resistance position corresponding to a speed of 1200 during cooling. In addition, the opening and closing angles of the air deflector are usually divided into five gears, and the number of operating steps of the stepper motor in each gear is fixed in the program. It cannot be guaranteed that the air outlet angle of the air deflector is the position with the minimum wind resistance at any air volume. The present invention establishes a dynamic matching mechanism between the fan air volume (speed) and the opening and closing angle of the air deflector, obtains the current position of the air deflector and the wind pressure signal in real time, and dynamically adjusts the operating speed and air outlet angle of the air deflector according to the change in wind pressure. It can automatically adjust the position of the air deflector according to any speed and any state to ensure that the air outlet angle of the air deflector is always at the position with the minimum wind resistance.

The controller is electrically connected with the sensor and a deflector driving mechanism, adjusts a running speed and a target position of the deflector according to the wind pressure signal collected by the sensor, so as to realize matching of the air outlet angle, and then realize adjustment of the position of the deflector, effectively reduce air resistance, and improve refrigeration or heating performance of the air conditioning system.
