[0015] Therefore, the scheme of the present invention, for an air conditioner having a small air guide plate 5 and a large air guide plate 6, and the small air guide plate 5 having an upward and downward sweeping function, for different gears of the wind gear X of the fan of the air conditioner indoor unit 1 of the air conditioner (such as super strong wind gear X1, high wind gear X2, high wind gear X3, medium wind gear X4, medium and low wind gear X5, low wind gear X6, and silent wind gear X7), determines the first angle range of the small air guide plate 5 when the wind gear X of the fan of the air conditioner indoor unit 1 is at the first wind gear (i.e., super strong wind gear X1 or high wind gear X2), and determines the first angle range of the small air guide plate 5 when the wind gear X of the fan of the air conditioner indoor unit 1 is at the second wind gear (i.e., high wind gear X1).

[0026] To make the objectives, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the specific embodiments of the present invention and the corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without any creative work shall fall within the protection scope of the present invention.

[0027] Based on an air conditioner with upper and lower air outlet functions, such as a split air conditioner with upper and lower air outlets, it can meet the requirements of an upper air outlet air conditioner where cold air does not blow directly on people. However, the reason cold air does not blow directly on people is that the cold air does not directly participate in heat exchange. Instead, it sinks due to gravity, and the cold is transferred through the plume, resulting in a significant reduction in the cooling effect and being completely unable to meet the same cooling effect as a regular air conditioner. Therefore, based on the large air deflector, a small air deflector needs to be added to achieve the cooling effect through up and down sweeping. Among them, the functions of the large air deflector and the small air deflector are to control the air outlet direction of the air conditioner's air outlet. The small air deflector directly controls the angle through a rotating shaft, and the large air deflector is pushed out through a driving shaft. The rotating shaft of the small air deflector and the driving shaft of the large air deflector can both reach the corresponding angles through the control of the air conditioner's electrical box. However, for an air conditioner with upper and lower air outlet functions, during the up and down sweeping process and after switching to each wind speed gear, the noise fluctuates greatly, resulting in a sharp whistling sound, which greatly affects the comfort of users when using the air conditioner. Therefore, the solution proposed in the present invention is a control method for an air conditioner, specifically an intelligent method for reducing the sharp whistling sound of the fluctuating noise during up and down sweeping. By adopting a simple method and increasing a small amount of cost, while improving the comfort and user experience of users, it can also meet the user's requirements for the cooling and heating functions of the air conditioner.

[0028] According to an embodiment of the present invention, there is provided a control method for an air conditioner, as Figure 1 shown in the flowchart of an embodiment of the method of the present invention. The air conditioner has an indoor unit (such as the air conditioner indoor unit 1), and the indoor unit has an indoor fan and an air outlet 4; at the air outlet 4, there is an air deflector, and the air deflector includes a first air deflector and a second air deflector. The first air deflector can sweep up and down within the air outlet range of the air outlet 4, and the second air deflector can adjust the air outlet direction of the air outlet 4. Among them, the first air deflector is like the small air deflector 5, and the second air deflector is like the large air deflector 6; Figure 2 It is a schematic diagram of the angle of the default position of the air deflector for cooling. As Figure 2 shown in the air conditioner indoor unit 1, it has an indoor heat exchanger (such as the evaporator 2), a cross-flow fan blade 3, an air outlet 4, a small air deflector 5, and a large air deflector 6. The evaporator 2 is located outside the cross-flow fan blade 3, the air outlet 4 is located at the outlet of the air duct of the air conditioner indoor unit 1, both the small air deflector 5 and the large air deflector 6 are located at the air outlet 4, and along the air outlet direction of the air outlet 4, the small air deflector 5 and the large air deflector 6 are arranged in sequence along this air outlet direction. Adapted to the small air deflector 5, there is a rotating shaft 7 of the small air deflector 5, and this rotating shaft 7 is used to control the up and down rotation of the small air deflector 5. Adapted to the large air deflector 6, there is a pushing shaft, and this pushing shaft is used to push out the large air deflector 6, that is, to push the large air deflector 6 from the closed position to a position at a corresponding angle, such as a position at a°. The control method of the air conditioner includes: step S110 to step S150.

[0029] At step S110, after the air conditioner is turned on, control the first air deflector and the second air deflector to be in their default positions in the current operating mode. In the solution of the present invention, the default positions of the air deflectors of the air conditioner are set, and these default positions are the angles of the air deflectors that can make the user feel the most comfortable. For example, during the cooling process, the air deflector is at an angle where the air blows upward without blowing directly at people, so that the cold air follows the ceiling.

[0030] Refer to Figure 2 In the example shown, the included angle between the large air deflector 6 and the horizontal plane is angle a. To ensure the aesthetic requirements of the appearance of the indoor unit 1 of the air conditioner, when the user sets the default position of the air deflector during the cooling process to an angle where the air does not blow directly at people, the small air deflector 5 is turned to the closed position (i.e., the small air deflector 5 is turned to an angle of 0°), and the large air deflector 6 is turned to Figure 2 the angle of a° in . Preferably, a° can be selected as 50°. That is to say, in the default position of the air deflector during the cooling process, specifically, the angle of the small air deflector 5 is turned to 0°, and the angle of the large air deflector 6 is turned to 50°. Among them, when the angle of the large air deflector 6 is turned to 50°, on the one hand, the large air deflector 6 is tilted upward from the ground to the ceiling direction, which can just partially block the air outlet 4, ensuring the aesthetic appearance of the indoor unit 1 of the air conditioner, so that when the height of the air outlet 4 of the air conditioner is between 1.75 m and 2.5 m above the ground, the user standing on the ground cannot see the air outlet 4 of the air conditioner; on the other hand, the air outlet of the air outlet 4 is larger and the cold air blows upward, which can ensure the fastest temperature drop rate during the cooling process on the basis of ensuring the aesthetic appearance of the indoor unit 1 of the air conditioner.

[0031] At step S120, during the operation of the air conditioner in the current operating mode, obtain the current wind speed setting of the indoor fan.

[0032] At step S130, determine whether the current wind speed setting of the indoor fan belongs to the first wind speed range in the set wind speed range or belongs to the second wind speed range in the set wind speed range; wherein, the lower limit of the first wind speed range is greater than the upper limit of the second wind speed range.

[0033] At step S140, if the current wind speed setting of the indoor fan belongs to the first wind speed range, control the first air deflector to sweep up and down within the first angle range of the first air deflector in the currently determined current operating mode.

[0034] At step S150, if the current wind speed of the indoor fan belongs to the second wind speed range, the first air guide plate is controlled to sweep the air up and down within the second angle range according to the predetermined second angle range of the first air guide plate in the current operating mode; wherein the first air guide plate in the first angle range and the first air guide plate in the second angle range both belong to part or all of the air outlet range of the air outlet (4).

[0035] The solution of the present invention proposes a method for intelligently reducing the whistling noise that fluctuates in noise during the up and down sweeping process. On the basis of the original air conditioner, an angle range in which the whistling noise is not obvious during the up and down sweeping process of the air guide plate is set, and intelligent control of the angle range in which the whistling noise is not obvious during the up and down sweeping process of the air guide plate is added, ensuring that the whistling noise is not obvious during the up and down sweeping process of the cooling function and the heating function, while ensuring the sweeping effect of each wind gear, ensuring that the whistling noise is not obvious, and effectively improving the user's comfort feeling when using the air conditioner. In this way, by taking simple methods as much as possible and increasing a small amount of cost, while improving the user's comfort and user experience, it can also meet the user's needs for the cooling function and heating function of the air conditioner.

[0036] In some embodiments, the first wind speed range includes: at least one of an ultra-strong wind speed and a high wind speed; the ultra-strong wind speed is greater than the high wind speed. The second wind speed range includes: at least one of a medium-high wind speed, a medium wind speed, a medium-low wind speed, a low wind speed, and a silent wind speed; the medium-high wind speed, the medium wind speed, the medium-low wind speed, the low wind speed, and the silent wind speed decrease in sequence.

[0037] In the scheme of the present invention, the wind speed X of the fan of the air-conditioning indoor unit 1 can be set to multiple wind speeds, such as the super wind speed X1 of the fan of the air-conditioning indoor unit 1, the high wind speed X2 of the fan of the air-conditioning indoor unit 1, the medium-high wind speed X3 of the fan of the air-conditioning indoor unit 1, the medium wind speed X4 of the fan of the air-conditioning indoor unit 1, the medium-low wind speed X5 of the fan of the air-conditioning indoor unit 1, the low wind speed X6 of the fan of the air-conditioning indoor unit 1, and the silent wind speed X7 of the fan of the air-conditioning indoor unit 1.

[0038] In the solution of the present invention, the angle range of the small wind guide plate 5 is intelligently controlled to ensure the wind sweeping effect of each windshield while ensuring that the whistling sound is not obvious. Figure 5 This is a control logic diagram of the angle range of the small air guide plate. Figure 5 As shown, the control logic of the angle range of the small air guide plate 5 includes:

[0039] Step 1: When the user enters the room, the air conditioner is turned on and the compressor is turned on, and the windshield X of the fan of the air conditioner indoor unit 1 is detected, and then step 2 is executed.

[0040] Step 2: When it is detected that the air volume gear of the fan of the indoor unit 1 of the air conditioner is the super-strong air volume gear X1 or the high air volume gear X2, the controller in the electric appliance box of the air conditioner controls the rotating shaft 7 of the small air deflector 5 to control the small air deflector 5 to swing within the first swing angle range Y1.

[0041] Step 3: When it is detected that the air volume gear of the fan of the indoor unit 1 of the air conditioner is not the super-strong air volume gear X1 or the high air volume gear X2, that is, when the air volume gear X of the fan of the indoor unit 1 of the air conditioner is other air volume gears except the super-strong air volume gear X1 or the high air volume gear X2, the controller in the electric appliance box of the air conditioner controls the rotating shaft 7 of the small air deflector 5 to control the small air deflector 5 to swing within the second swing angle range Y2, which can effectively ensure that during the swing of the small air deflector 5 at different air volume gears, the small air deflector 5 is in a position where the whistling sound is not obvious, ensuring the swing effect and improving the user comfort at the same time.

[0042] The noise test values under the super-strong air volume gear X1 are as follows. The peak value at the peak frequency of 652 Hz exceeds 40 dB, and the whistling sound is obvious, seriously affecting the comfort of users using the air conditioner. While the normal noise, such as the noise of normal wind sound, has a peak value less than 35 dB at the peak frequency of 652 Hz, which is a normal wind sound. It is verified that the solution of the present invention can effectively ensure that during the swing of the small air deflector 5 at different air volume gears, the small air deflector 5 is in a position where the whistling sound is not obvious, ensuring the swing effect and improving the user comfort at the same time.

[0043]

[0044]

[0045] The solution of the present invention can, aiming at the noise problem when the air conditioner switches different air volume gears, control the angle range of the small air deflector 5 to ensure that the whistling sound is not obvious while ensuring the swing effect of each air volume gear; on the basis of the original air conditioner, increase the angle range where the whistling sound is not obvious during the up and down swing of the small air deflector 5, and at the same time increase the control logic for intelligently controlling the angle range where the whistling sound is not obvious during the up and down swing of the small air deflector 5, ensuring that the whistling sound is obvious during the up and down swing in the cooling function and the heating function, ensuring that the whistling sound is not obvious while ensuring the swing effect of switching each air volume gear, and effectively improving the comfort feeling of users using the air conditioner.

[0046] In some embodiments, denote the included angle between the center line of the air outlet 4 and the horizontal plane as the intermediate angle of the air outlet 4 (such as angle c1), and denote the included angle between the lower edge of the air outlet of the air outlet 4 and the horizontal plane as the maximum angle of the air outlet 4 (such as angle c2).

[0047] Specifically, Figure 3 It is a schematic diagram of the angle range of the small air deflector where the whistling sound is not obvious during the up and down swing of the super-strong air volume gear and the high air volume gear. Figure 3In the example shown, the central axis of the air outlet 4 is the air outlet center line 8. The angle between the air outlet center line 8 and the horizontal plane, i.e., the center line angle, is angle c1, and this center line angle is the intermediate angle of the air outlet 4. The maximum angle of the air outlet 4 is angle c2.

[0048] When the air volume gear X of the fan of the air conditioner indoor unit 1 is set to the super strong air volume gear X1 or the high air volume gear X2, the rotational speed of the fan of the air conditioner indoor unit 1 is high and the air volume of the cross-flow air blade 3 of the fan of the air conditioner indoor unit 1 is large. During the up-and-down sweeping of the small air deflector 5, when the small air deflector 5 passes through the intermediate position of the air outlet 4 (i.e., the position where the central axis of the line connecting the upper edge and the lower edge of the air outlet 4 is the air outlet center line 8), the small air deflector 5 is parallel to the air outlet direction of the air outlet 4, with small air pressure loss and high wind speed; when the small air deflector 5 passes through both sides of the air outlet 4 (i.e., the upper edge and the lower edge of the air outlet 4), the air pressure loss is large. Therefore, when the small air deflector 5 passes through the intermediate position of the air outlet 4, a sharp whistling sound that varies in magnitude will be generated due to the change in air volume. To ensure the sweeping effect of the small air deflector 5, it has been verified that when the air volume gear X of the fan of the air conditioner indoor unit 1 is set to the super strong air volume gear X1 or the high air volume gear X2, the angle range with insignificant whistling sound during the up-and-down sweeping of the small air deflector 5 is the first sweeping angle range Y1 of the small air deflector 5, so that the small air deflector 5 does not hit the intermediate position of the air outlet 4, that is, the small air deflector 5 does not hit the most smooth position parallel to the air outlet direction of the air outlet 4, resulting in small air volume and low total noise value.

[0049] Within the first angle range of the first air deflector, the minimum angle between the lower edge of the sweeping of the first air deflector and the horizontal plane is denoted as the first sweeping angle (such as Figure 3 the angle b1 shown), and the maximum angle between the upper edge of the sweeping of the first air deflector and the horizontal plane is denoted as the second sweeping angle (such as Figure 3 the angle b2 shown); that is to say, the upper limit of the first angle range of the first air deflector is the second sweeping angle, and the lower limit of the first angle range of the first air deflector is the first sweeping angle.

[0050] Specifically, referring to the example shown in Figure 3 within the first sweeping angle range Y1 of the small air deflector 5, the angle between the lower edge of the sweeping of the small air deflector 5 and the horizontal plane is angle b1, and the angle between the upper edge of the sweeping of the small air deflector 5 and the horizontal plane is angle b2.

[0051] Among them, since the density of the hot air for heating is low and the hot air floats upward, while the cold air for cooling sinks downward, there are differences in angles. Therefore, there are distinctions between the cooling function and the heating function. In the heating function, the angle b1 is greater than the angle c1 so that the lower edge of the sweeping of the small air deflector 5 is higher than the center line 8 of the air outlet. In the cooling function, the angle b1 is equal to the angle c1 so that the whistling sound is not obvious during the up-and-down sweeping process of the small air deflector 5 in both the heating function and the cooling function. To ensure the condensation effect in the cooling function, the angle b2 is less than the angle c2 in the cooling function so that there is a certain gap between the upper edge of the sweeping of the small air deflector 5 and the lower edge of the air outlet of the air outlet 4. In this way, cold air blows through this gap, and there is no accumulation of hot air on the surface of the small air deflector 5 and the lower edge of the air outlet of the air outlet 4, which can well improve the condensation phenomenon and even ensure that no condensed water appears. In the heating function, the angle b2 is equal to the angle c2 to limit the maximum position of the sweeping angle so that the whistling sound is not obvious during the up-and-down sweeping process of the small air deflector 5 in the heating function.

[0052] In the solution of the present invention, when the air volume gear X of the fan of the indoor unit 1 of the air conditioner is other than the super-strong air volume gear X1 or the high air volume gear X2, the rotational speed of the fan of the indoor unit 1 of the air conditioner is low, the air volume of the cross-flow fan blade 3 of the fan of the indoor unit 1 of the air conditioner is small, the total noise value is small, and the whistling sound is not obvious. To ensure the sweeping effect of the small air deflector 5, it has been verified that when the air volume gear X of the fan of the indoor unit 1 of the air conditioner is set to be other than the super-strong air volume gear X1 or the high air volume gear X2, the angle range of the small air deflector 5 where the whistling sound is not obvious during the up-and-down sweeping process is the second sweeping angle range Y2 of the small air deflector 5, so as to increase the sweeping range of the small air deflector 5 as much as possible, increase the air volume output from the air outlet 4, and improve the cooling or heating effect of the air conditioner.

[0053] Within the second angle range of the first air deflector, the minimum included angle between the lower edge of the sweeping of the first air deflector and the horizontal plane is recorded as the third sweeping angle (such as Figure 4 the angle b3 shown), and the maximum included angle between the upper edge of the sweeping of the first air deflector and the horizontal plane is recorded as the second sweeping angle (such as Figure 4 the angle b2 shown). That is to say, the upper limit of the second angle range of the first air deflector is the second sweeping angle, and the lower limit of the second angle range of the first air deflector is the third sweeping angle.

[0054] Specifically, Figure 4 It is a schematic diagram of the angle range of the small air deflector where the whistling sound is not obvious during the up-and-down sweeping process for other air volume gears except the super-strong air volume gear and the high air volume gear. In Figure 4 the example shown, within the second sweeping angle range Y2 of the small air deflector 5, the included angle between the lower edge of the sweeping of the small air deflector 5 and the horizontal plane is the angle b3, and the included angle between the upper edge of the sweeping of the small air deflector 5 and the horizontal plane is the angle b2. Among them, the angle b3 is less than the angle c1.

[0055] In some embodiments, the current operation mode is a cooling mode or a heating mode. In the cooling mode, the first air sweeping angle (such as Figure 3 The angle b1 shown in FIG. 1 is equal to the middle angle of the air outlet 4 (such as angle c1), and the second sweeping angle (such as Figure 3 or Figure 4 The angle b2 shown in FIG. 1 is smaller than the maximum angle of the air outlet 4 (such as the angle c2), and the third sweeping angle (such as Figure 4 The angle b3 shown in FIG. 1 is equal to 0°. In the heating mode, the first sweeping angle ( Figure 3 The angle b1 shown in the figure is greater than the middle angle of the air outlet 4 (such as the angle c1), and the second sweeping angle (such as Figure 3 or Figure 4 The angle b2 shown in FIG. 1 is equal to the maximum angle of the air outlet 4 (such as angle c2), and the third sweeping angle (such as Figure 4 The angle b3) shown is equal to 0°.

[0056] For example, the middle angle of the air outlet of the air outlet 4 of the air conditioner, namely angle c1, is preferably 35°, and the maximum angle of the air outlet of the air outlet 4 of the air conditioner, namely angle c2, is preferably 60°. In the cooling function of the air conditioner, angle b1 is preferably 35°, angle b2 is preferably 55°, angle b3 is preferably 0°, the first sweeping angle range Y1 of the small air guide plate 5 is preferably 35° to 55°, and the second sweeping angle range Y2 of the small air guide plate 5 is preferably 0° to 55°. In this way, by controlling the angle range in which the whistling sound is not obvious during the up and down sweeping of the small air guide plate 5 of the air conditioner during the cooling process, the sharp whistling sound caused by the fluctuating noise during the up and down sweeping of the small air guide plate 5 of the air conditioner is reduced, and the gear X of the fan of the air conditioner indoor unit 1 is reduced when switching between different wind gears to ensure the wind sweeping effect of switching each wind gear while ensuring that the whistling sound is not obvious. In the heating function of the air conditioner, the angle b1 is preferably 40°, the angle b2 is preferably 60°, the angle b3 is preferably 0°, the first sweeping angle range Y1 of the small air guide plate 5 is preferably 40°~60°, and the second sweeping angle range Y2 of the small air guide plate 5 is preferably 0°~60°. In this way, by controlling the angle range in which the whistling sound is not obvious during the up and down sweeping process of the small air guide plate 5 of the air conditioner during the heating process, the sharp whistling sound caused by the fluctuating noise during the up and down sweeping process of the small air guide plate 5 of the air conditioner is reduced, and the gear X of the fan of the air conditioner indoor unit 1 is reduced when switching between different wind gears to ensure the sweeping effect of switching each wind gear while ensuring that the whistling sound is not obvious.

[0057] By adopting the technical solution of this embodiment, for an air conditioner having a small air guide plate 5 and a large air guide plate 6, and the small air guide plate 5 having an upward and downward sweeping function, for different gears of the wind gear X of the fan of the air conditioner indoor unit 1 of the air conditioner (such as super strong wind gear X1, high wind gear X2, high wind gear X3, medium wind gear X4, medium and low wind gear X5, low wind gear X6, and silent wind gear X7), it is determined that the first angle range of the small air guide plate 5 when the wind gear X of the fan of the air conditioner indoor unit 1 is at the first wind gear (i.e., super strong wind gear X1 or high wind gear X2), and the wind gear X of the fan of the air conditioner indoor unit 1 is at the second wind gear (i.e., high wind gear X3). When the air conditioner is turned on and the air speed X of the fan of the indoor unit 1 of the air conditioner is at the first wind speed or the second wind speed, the small air guide plate 5 is controlled to sweep the air up and down within the corresponding angle range. Therefore, by controlling the angle range in which the whistling sound is not obvious during the up and down sweeping process of the small air guide plate 5 of the air conditioner, the sharp whistling sound caused by the fluctuating noise during the up and down sweeping process is reduced, and the comfort feeling of the user when using the air conditioner is improved.

[0058] According to an embodiment of the present invention, a control device for an air conditioner corresponding to the control method for an air conditioner is also provided. Figure 6 The schematic diagram of the structure of an embodiment of the device of the present invention is shown. The air conditioner has an indoor unit (such as the air conditioner indoor unit 1), and the indoor unit has an indoor fan and an air outlet 4; an air guide plate is arranged at the air outlet 4, and the air guide plate includes a first air guide plate and a second air guide plate, the first air guide plate can sweep the air up and down within the air outlet range of the air outlet 4, and the second air guide plate can adjust the air outlet direction of the air outlet 4, wherein the first air guide plate is such as a small air guide plate 5, and the second air guide plate is such as a large air guide plate 6; Figure 2 This is a schematic diagram of the default cooling position of the air guide plate. Figure 2 The air conditioner indoor unit 1 shown has an indoor heat exchanger (such as an evaporator 2), a crossflow blade 3, an air outlet 4, a small air guide plate 5 and a large air guide plate 6. The evaporator 2 is located at the periphery of the crossflow blade 3, the air outlet 4 is located at the outlet of the air duct of the air conditioner indoor unit 1, the small air guide plate 5 and the large air guide plate 6 are both located at the air outlet 4, and along the air outlet direction of the air outlet 4, the small air guide plate 5 and the large air guide plate 6 are arranged in sequence along the air outlet direction. A rotating shaft 7 of the small air guide plate 5 is provided to match the small air guide plate 5, and the rotating shaft 7 is used to control the small air guide plate 5 to rotate up and down. A driving shaft is provided to match the large air guide plate 6, and the driving shaft is used to push the large air guide plate 6 out. The control device of the air conditioner includes: an acquisition unit 102 and a control unit 104.

[0059] Among them, the control unit 104 is configured to control the first air deflector and the second air deflector to be in the default positions in the current operating mode respectively after the air conditioner is turned on. For the specific functions and processes of this control unit 104, refer to step S110. In the solution of the present invention, the default positions of the air deflector of the air conditioner are set, and the default positions of the air deflector are the angles of the air deflector that can make the user feel the most comfortable. For example: during the refrigeration process, the air deflector is at an angle of upward air outlet without blowing directly at people, so that the cold air follows the ceiling.

[0060] Refer to Figure 2 In the example shown, the included angle between the large air deflector 6 and the horizontal plane is angle a. To meet the aesthetic requirements of the appearance of the indoor unit 1 of the air conditioner, when the user sets the default position of the air deflector during the refrigeration process to an angle of refrigeration without blowing directly at people, the small air deflector 5 is turned to the closed position (that is, the small air deflector 5 is turned to an angle of 0°), and the large air deflector 6 is turned to Figure 2 the a° angle in. Preferably, a° can be selected as 50°, that is to say, the default position of the air deflector during the refrigeration process can specifically be: the angle of the small air deflector 5 is turned to 0°, and the angle of the large air deflector 6 is turned to 50°. Among them, when the angle of the large air deflector 6 is turned to 50°, on the one hand, the large air deflector 6 is tilted upward from the ground to the ceiling direction, which can just partially block the air outlet 4, ensuring the aesthetic appearance of the indoor unit 1 of the air conditioner, so that when the height of the air outlet 4 of the air conditioner is between 1.75 m and 2.5 m from the ground, the user standing on the ground cannot see the air outlet 4 of the air conditioner; on the other hand, the air vent of the air outlet 4 is larger and the cold air blows upward, which can ensure the fastest temperature drop rate during the refrigeration process on the basis of ensuring the aesthetic appearance of the indoor unit 1 of the air conditioner.

[0061] The acquisition unit 102 is configured to acquire the current air volume gear of the indoor blower during the operation of the air conditioner in the current operating mode. For the specific functions and processes of this control unit 104, refer to step S120.

[0062] The control unit 104 is further configured to determine whether the current air volume gear of the indoor blower belongs to the first air volume gear range in the set air volume gear range or belongs to the second air volume gear range in the set air volume gear range; among them, the lower limit of the first air volume gear range is greater than the upper limit of the second air volume gear range. For the specific functions and processes of this control unit 104, refer to step S130.

[0063] The control unit 104 is further configured to, if the current air volume gear of the indoor blower belongs to the first air volume gear range, control the first air deflector to sweep up and down within the first angle range of the first air deflector in the currently determined current operating mode; for the specific functions and processes of this control unit 104, refer to step S140.

[0064] The control unit 104 is further configured to control the first air guide plate to sweep air up and down within the second angle range according to the predetermined second angle range of the first air guide plate in the current operation mode if the current wind speed of the indoor fan belongs to the second wind speed range; wherein the first air guide plate in the first angle range and the first air guide plate in the second angle range both belong to a part or all of the air outlet range of the air outlet (4). The specific functions and processing of the control unit 104 are also referred to step S150.

[0065] The solution of the present invention proposes an intelligent device for reducing the whistling noise that fluctuates in noise during the up and down sweeping process. On the basis of the original air conditioner, an angle range in which the whistling noise is not obvious during the up and down sweeping process of the air guide plate is set, and intelligent control of the angle range in which the whistling noise is not obvious during the up and down sweeping process of the air guide plate is added, ensuring that the whistling noise is not obvious during the up and down sweeping process of the cooling function and the heating function, while ensuring the sweeping effect of each wind gear, ensuring that the whistling noise is not obvious, and effectively improving the user's comfort feeling when using the air conditioner. In this way, by adopting simple devices as much as possible and increasing a small amount of cost, while improving the user's comfort and user experience, it can also meet the user's needs for the cooling function and heating function of the air conditioner.

[0066] In some embodiments, the first wind speed range includes: at least one of an ultra-strong wind speed and a high wind speed; the ultra-strong wind speed is greater than the high wind speed. The second wind speed range includes: at least one of a medium-high wind speed, a medium wind speed, a medium-low wind speed, a low wind speed, and a silent wind speed; the medium-high wind speed, the medium wind speed, the medium-low wind speed, the low wind speed, and the silent wind speed decrease in sequence.

[0067] In the scheme of the present invention, the wind speed X of the fan of the air-conditioning indoor unit 1 can be set to multiple wind speeds, such as the super wind speed X1 of the fan of the air-conditioning indoor unit 1, the high wind speed X2 of the fan of the air-conditioning indoor unit 1, the medium-high wind speed X3 of the fan of the air-conditioning indoor unit 1, the medium wind speed X4 of the fan of the air-conditioning indoor unit 1, the medium-low wind speed X5 of the fan of the air-conditioning indoor unit 1, the low wind speed X6 of the fan of the air-conditioning indoor unit 1, and the silent wind speed X7 of the fan of the air-conditioning indoor unit 1.

[0068] In the solution of the present invention, the angle range of the small wind guide plate 5 is intelligently controlled to ensure the wind sweeping effect of each windshield while ensuring that the whistling sound is not obvious. Figure 5 This is a control logic diagram of the angle range of the small air guide plate. Figure 5 As shown, the control logic of the angle range of the small air guide plate 5 includes:

[0069] Step 1: When the user enters the room and the air conditioner is turned on and the compressor is running, detect the wind speed X of the fan in the indoor unit 1 of the air conditioner, and then proceed to Step 2.

[0070] Step 2: When it is detected that the wind speed of the fan in the indoor unit 1 of the air conditioner is the super-strong wind speed X1 or the high wind speed X2, the controller in the electrical box of the air conditioner controls the rotating shaft 7 of the small air deflector 5 to control the small air deflector 5 to swing within the first swing angle range Y1.

[0071] Step 3: When it is detected that the wind speed of the fan in the indoor unit 1 of the air conditioner is not the super-strong wind speed X1 or the high wind speed X2, that is, when the wind speed X of the fan in the indoor unit 1 of the air conditioner is other wind speeds except the super-strong wind speed X1 or the high wind speed X2, the controller in the electrical box of the air conditioner controls the rotating shaft 7 of the small air deflector 5 to control the small air deflector 5 to swing within the second swing angle range Y2, which can effectively ensure that during the swinging process of the small air deflector 5 at different wind speeds, the small air deflector 5 is in a position where the whistling sound is not obvious, ensuring the swinging effect while improving the user's comfort.

[0072] The noise test values at the super-strong wind speed X1 are as follows. The peak at the peak frequency of 652 Hz exceeds 40 dB, and the whistling sound is obvious, seriously affecting the comfort of the user using the air conditioner. While the normal noise, such as the noise of normal wind, has a peak less than 35 dB at the peak frequency of 652 Hz. It has been verified that the solution of the present invention can effectively ensure that during the swinging process of the small air deflector 5 at different wind speeds, the small air deflector 5 is in a position where the whistling sound is not obvious, ensuring the swinging effect while improving the user's comfort.

[0073]

[0074] The solution of the present invention can control the angle range of the small air deflector 5 for the noise problem when the air conditioner switches between different wind speeds, ensuring the swinging effect at each wind speed while ensuring that the whistling sound is not obvious; on the basis of the original air conditioner, increasing the angle range where the whistling sound is not obvious during the up and down swinging of the small air deflector 5, and at the same time adding the control logic for intelligently controlling the angle range where the whistling sound is not obvious during the up and down swinging of the small air deflector 5, ensuring that the whistling sound is obvious during the up and down swinging in the cooling and heating functions, ensuring that the whistling sound is not obvious while ensuring the swinging effect when switching between each wind speed, effectively improving the comfort of the user using the air conditioner.

[0075] In some embodiments, denote the angle between the center line of the air outlet 4 and the horizontal plane as the middle angle of the air outlet 4 (such as angle c1), and denote the angle between the lower edge of the air outlet of the air outlet 4 and the horizontal plane as the maximum angle of the air outlet 4 (such as angle c2).

[0076] Specifically, Figure 3Schematic diagram of the angle range of the small air deflector where the whistling sound is not obvious during the up and down sweeping of the super-strong air deflector and the high air deflector. In Figure 3 In the example shown, the central axis of the air outlet 4 is the air outlet center line 8. The angle between the air outlet center line 8 and the horizontal plane, i.e., the center line angle, is angle c1, and this center line angle is the intermediate angle of the air outlet 4. The maximum angle of the air outlet 4 is angle c2.

[0077] When the air deflector X of the blower of the air conditioner indoor unit 1 is set to the super-strong air deflector X1 or the high air deflector X2, the rotational speed of the blower of the air conditioner indoor unit 1 is high and the air volume of the cross-flow air blade 3 of the blower of the air conditioner indoor unit 1 is large. During the up and down sweeping of the small air deflector 5, when the small air deflector 5 passes through the intermediate position of the air outlet 4 (i.e., the position where the central axis of the line connecting the upper edge and the lower edge of the air outlet 4 is the air outlet center line 8), the small air deflector 5 is parallel to the air outlet direction of the air outlet 4, with small air pressure loss and high wind speed; when the small air deflector 5 passes through both sides of the air outlet 4 (i.e., the upper edge and the lower edge of the air outlet 4), the air pressure loss is large. Therefore, when the small air deflector 5 passes through the intermediate position of the air outlet 4, a sharp whistling sound that varies in size will be generated due to the change in the air volume. To ensure the air sweeping effect of the small air deflector 5, it has been verified that when the air deflector X of the blower of the air conditioner indoor unit 1 is set to the super-strong air deflector X1 or the high air deflector X2, the angle range where the whistling sound is not obvious during the up and down sweeping of the small air deflector 5 is the first air sweeping angle range Y1 of the small air deflector 5, so that the small air deflector 5 does not hit the intermediate position of the air outlet 4, that is, the small air deflector 5 does not hit the most smooth position parallel to the air outlet direction of the air outlet 4, resulting in a small air volume and a small total noise value.

[0078] Within the first angle range of the first air deflector, the minimum angle between the lower edge of the air sweeping of the first air deflector and the horizontal plane is recorded as the first air sweeping angle (such as Figure 3 the angle b1 shown), and the maximum angle between the upper edge of the air sweeping of the first air deflector and the horizontal plane is recorded as the second air sweeping angle (such as Figure 3 the angle b2 shown). That is to say, the upper limit of the first angle range of the first air deflector is the second air sweeping angle, and the lower limit of the first angle range of the first air deflector is the first air sweeping angle.

[0079] Specifically, referring to the example shown in Figure 3 within the first air sweeping angle range Y1 of the small air deflector 5, the angle between the lower edge of the air sweeping of the small air deflector 5 and the horizontal plane is angle b1, and the angle between the upper edge of the air sweeping of the small air deflector 5 and the horizontal plane is angle b2.

[0080] Among them, there is a distinction between the refrigeration function and the heating function. In the heating function, the angle b1 is greater than the angle c1 so that the lower edge of the sweeping of the small air deflector 5 is higher than the center line 8 of the air outlet. In the refrigeration function, the angle b1 is equal to the angle c1 so that the whistling sound is not obvious during the up and down sweeping of the small air deflector 5 in the heating and refrigeration functions. To ensure the condensation effect in the refrigeration function, the angle b2 is less than the angle c2 in the refrigeration function so that there is a certain gap between the upper edge of the sweeping of the small air deflector 5 and the lower edge of the air outlet of the air outlet 4. In this way, cold air blows through this gap, and there is no hot air gathering on the surface of the small air deflector 5 and the lower edge of the air outlet of the air outlet 4, which can well improve the condensation phenomenon and even ensure that no condensed water appears. In the heating function, the angle b2 is equal to the angle c2 so that the whistling sound is not obvious during the up and down sweeping of the small air deflector 5 in the heating function.

[0081] In the solution of the present invention, when the air volume gear X of the blower of the indoor unit 1 of the air conditioner is other than the super-strong air volume gear X1 or the high air volume gear X2, the rotational speed of the blower of the indoor unit 1 of the air conditioner is low, the air volume of the cross-flow air blade 3 of the blower of the indoor unit 1 of the air conditioner is small, the total noise value is small, and the whistling sound is not obvious. To ensure the sweeping effect of the small air deflector 5, it has been verified that when the air volume gear X of the blower of the indoor unit 1 of the air conditioner is set to be other than the super-strong air volume gear X1 or the high air volume gear X2, the angle range of the second sweeping angle range Y2 of the small air deflector 5 where the whistling sound is not obvious during the up and down sweeping of the small air deflector 5 is used to increase the sweeping range of the small air deflector 5 as much as possible, increase the air volume of the air outlet 4, and improve the refrigeration or heating effect of the air conditioner.

[0082] Within the second angle range of the first air deflector, the minimum included angle between the lower edge of the sweeping of the first air deflector and the horizontal plane is recorded as the third sweeping angle (such as Figure 4 the angle b3 shown), and the maximum included angle between the upper edge of the sweeping of the first air deflector and the horizontal plane is recorded as the second sweeping angle (such as Figure 4 the angle b2 shown). That is to say, the upper limit of the second angle range of the first air deflector is the second sweeping angle, and the lower limit of the second angle range of the first air deflector is the third sweeping angle.

[0083] Specifically, Figure 4 It is a schematic diagram of the angle range of the small air deflector where the whistling sound is not obvious during the up and down sweeping for other air volume gears except the super-strong air volume gear and the high air volume gear. In Figure 4 the example shown, within the second sweeping angle range Y2 of the small air deflector 5, the included angle between the lower edge of the sweeping of the small air deflector 5 and the horizontal plane is the angle b3, and the included angle between the upper edge of the sweeping of the small air deflector 5 and the horizontal plane is the angle b2. Among them, the angle b3 is less than the angle c1.

[0084] In some embodiments, the current operating mode is the refrigeration mode or the heating mode. In the refrigeration mode, the first sweeping angle (such asFigure 3 The angle b1 shown in FIG. 1 is equal to the middle angle of the air outlet 4 (such as angle c1), and the second sweeping angle (such as Figure 3 or Figure 4 The angle b2 shown in FIG. 1 is smaller than the maximum angle of the air outlet 4 (such as the angle c2), and the third sweeping angle (such as Figure 4 The angle b3 shown in FIG. 1 is equal to 0°. In the heating mode, the first sweeping angle ( Figure 3 The angle b1 shown in the figure is greater than the middle angle of the air outlet 4 (such as the angle c1), and the second sweeping angle (such as Figure 3 or Figure 4 The angle b2 shown in FIG. 1 is equal to the maximum angle of the air outlet 4 (such as angle c2), and the third sweeping angle (such as Figure 4 The angle b3) shown is equal to 0°.

[0085] For example, the middle angle of the air outlet of the air outlet 4 of the air conditioner, namely angle c1, is preferably 35°, and the maximum angle of the air outlet of the air outlet 4 of the air conditioner, namely angle c2, is preferably 60°. In the cooling function of the air conditioner, angle b1 is preferably 35°, angle b2 is preferably 55°, angle b3 is preferably 0°, the first sweeping angle range Y1 of the small air guide plate 5 is preferably 35° to 55°, and the second sweeping angle range Y2 of the small air guide plate 5 is preferably 0° to 55°. In this way, by controlling the angle range in which the whistling sound is not obvious during the up and down sweeping of the small air guide plate 5 of the air conditioner during the cooling process, the sharp whistling sound caused by the fluctuating noise during the up and down sweeping of the small air guide plate 5 of the air conditioner is reduced, and the gear X of the fan of the air conditioner indoor unit 1 is reduced when switching between different wind gears to ensure the wind sweeping effect of switching each wind gear while ensuring that the whistling sound is not obvious. In the heating function of the air conditioner, the angle b1 is preferably 40°, the angle b2 is preferably 60°, the angle b3 is preferably 0°, the first sweeping angle range Y1 of the small air guide plate 5 is preferably 40°~60°, and the second sweeping angle range Y2 of the small air guide plate 5 is preferably 0°~60°. In this way, by controlling the angle range in which the whistling sound is not obvious during the up and down sweeping process of the small air guide plate 5 of the air conditioner during the heating process, the sharp whistling sound caused by the fluctuating noise during the up and down sweeping process of the small air guide plate 5 of the air conditioner is reduced, and the gear X of the fan of the air conditioner indoor unit 1 is reduced when switching between different wind gears to ensure the sweeping effect of switching each wind gear while ensuring that the whistling sound is not obvious.
