[0057] In the description of the present invention, if there is a description of first and second, it is only for the purpose of distinguishing the technical features, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0058] In the description of the present invention, it should be noted that the terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention in combination with the specific content of the technical solution.

[0059] The technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the embodiments described below are only some embodiments of the present invention, not all embodiments.

[0060] In the related art, an air guide assembly is provided at the air outlet of the indoor unit of a wall-mounted air conditioner, and the air guide assembly is used to guide the air blown out of the air outlet. The air guide assembly usually adopts a combination of an outer air guide plate and an inner air guide plate, wherein the outer air guide plate is used to open or close the air outlet, and the inner air guide plate is smaller in size and is located on the inner side of the outer air guide plate. Since the inner air guide plate is used to guide the air in both the cooling mode and the heating mode, the air supply range is not large, and the cooling or heating effect is not good.

[0061] In order to solve the above problems, an embodiment of the present invention proposes an air conditioner indoor unit 1000, which is specifically a wall-mounted air conditioner indoor unit. Figures 1 to 7 The air conditioner indoor unit 1000 according to an embodiment of the present invention is introduced.

[0062] Reference Figure 1 , Figure 2 and Figure 3 As shown, the air-conditioning indoor unit 1000 of the embodiment of the present invention includes a shell 100 and an air guide assembly 200, the shell 100 is provided with an air inlet 110 and an air outlet 120, an air duct 411 is formed in the shell 100, the air inlet 110 and the air outlet 120 are both connected to the air duct 411, wherein the air inlet 110 is located at the top of the shell 100, the air outlet 120 is located at the lower part of the shell 100 and is inclined downward, the air guide assembly 200 is connected to the shell 100 and is located at the air outlet 120, and the air outlet of the air outlet 120 can be guided by the air guide assembly 200 so that the air outlet can be blown into the room. Figures 1 to 3 All shown are cross-sectional schematic diagrams of the air conditioner indoor unit 1000 .

[0063] It is understandable that the air conditioner indoor unit 1000 also includes a heat exchanger 300 and a fan 400, which are arranged in the housing 100, wherein the fan 400 is a cross-flow fan, specifically including a volute 410 and a wind wheel 420, the wind wheel 420 is arranged in the volute 410, and a wind duct 411 is formed in the volute 410. When the fan 400 is working, it can drive the airflow from the air inlet 110 into the housing 100, and generate hot air or cold air after heat exchange in the heat exchanger 300. The hot air or cold air can flow along the wind duct 411 to the air outlet 120 and blow into the room, thereby achieving heating or cooling. This is only an example. In some embodiments, the fan 400 can also be an axial flow fan, which is selected according to actual application requirements.

[0064] In the embodiment, the air guide assembly 200 includes a first air guide plate 210, a second air guide plate 220 and a third air guide plate 230. The first air guide plate 210, the second air guide plate 220 and the third air guide plate 230 are respectively arranged along the length direction of the air outlet 120. The above three air guide plates are rotatably connected to the housing 100. The air outlet 120 is formed with a first wall surface 121 and a second wall surface 122 arranged opposite to each other. Figure 1 The direction shown is used as a reference direction. The first wall 121 can be understood as the upper wall of the air outlet 120, and the second wall 122 can be understood as the lower wall of the air outlet 120. The first wall 121 and the second wall 122 are respectively connected to the side walls of the air duct 411.

[0065] Specifically, the housing 100 includes a face frame 130, which includes a front side plate and a lower side plate, the air outlet 120 is formed between the front side plate and the lower side plate, the lower side edge of the front side plate is connected to the volute tongue 412 of the volute 410, the lower side plate is connected to the side wall of the volute 410 relative to the volute tongue 412, the first wall surface 121 is formed between the volute tongue 412 and the front side plate, and the second wall surface 122 is formed on the side of the lower side plate facing the air outlet 120. Among them, the first air guide plate 210 is arranged at an end of the first wall surface 121 away from the air duct 411, and the third air guide plate 230 is arranged at an end of the second wall surface 122 away from the air duct 411, that is, the first air guide plate 210 is located at the lower side of the front side plate, the third air guide plate 230 is located at the front side of the lower side plate, and the second air guide plate 220 is located between the first air guide plate 210 and the third air guide plate 230.

[0066] It can be understood that this is only an example, and the first wall surface 121 may also be integrally formed with the face frame 130 , and the second wall surface 122 may also be integrally formed with the volute 410 , without any specific limitation.

[0067] Combination Figure 2 and Figure 3 To illustrate, by rotating the first air guide plate 210, the second air guide plate 220 and the third air guide plate 230, the angle can be adjusted to change the air outlet direction. It can be understood that when the air outlet 120 is in the open state, the air guide assembly 200 is configured to have a first air guide state or a second air guide state. Specifically, Figure 2 The figure shows the air supply state of the air conditioner indoor unit 1000 in the heating mode. The first air guide plate 210, the second air guide plate 220 and the third air guide plate 230 are all rotated to the vertical downward direction. At this time, it is the first air guide state. The first air guide plate 210 and the second air guide plate 220 are arranged in sequence along the air flow direction of the air outlet 120 to guide the air, so that the first air guide plate 210 and the second air guide plate 220 can cooperate to extend the air guide area of ​​the upper wall of the air outlet 120, and the third air guide plate 230 extends the air guide area of ​​the lower wall of the air outlet 120. Figure 2The direction of the dotted arrow at the middle air outlet 120 is the air flow direction.

[0068] Figure 3 The figure shows the air supply state of the air conditioner indoor unit 1000 in the cooling mode. The first air guide plate 210, the second air guide plate 220 and the third air guide plate 230 are all rotated to the direction facing the front side. At this time, it is the second air guide state. The third air guide plate 230 and the second air guide plate 220 are arranged in sequence along the air flow direction of the air outlet 120 to guide the air, so that the third air guide plate 230 and the second air guide plate 220 can cooperate to extend the air guide area of ​​the lower wall of the air outlet 120, and the first air guide plate 210 extends the air guide area of ​​the upper wall of the air outlet 120. Figure 3 The direction of the dotted arrow at the middle air outlet 120 is the air flow direction.

[0069] It can be understood that in the heating mode, the hot air is supplied downwardly through the air guide component 200, and the hot air first reaches the lower area of ​​the indoor space. Since the hot air flow will slowly diffuse upward, the indoor temperature will rise more quickly and the heating effect will be better. In the cooling mode, the hot air is supplied toward the front or obliquely downwardly through the air guide component 200, and the cold air flow will gradually diffuse from top to bottom, and the cooling effect will be better.

[0070] It should be noted that, since the first air guide plate 210 is connected to one end of the first wall 121 away from the air duct 411, and the third air guide plate 230 is connected to one end of the second wall 122 away from the air duct 411, the first air guide plate 210 can be used as an extension of the upper mold line of the air outlet 120, and the third air guide plate 230 can be used as an extension of the lower mold line of the air outlet 120, wherein the upper mold line and the lower mold line can also be understood as the upper contour line and the lower contour line of the cross-section of the air outlet 120, and the air guide area recorded in this article can be understood as the above-mentioned extension.

[0071] Understandably, Figure 2 In the air outlet state shown, the upper profile of the air outlet 120 can be further extended by cooperating with the first air guide plate 210 and the second air guide plate 220. At this time, the air outlet 120 supplies air downward. Figure 3 In the air outlet state shown, the third air guide plate 230 cooperates with the second air guide plate 220 to further extend the lower profile of the air outlet 120. At this time, the air outlet 120 can supply air in an inclined downward or front direction.

[0072] Compared with the combination of an outer air guide plate and an inner air guide plate in the related art, the air guide assembly 200 of the embodiment of the present invention extends the upper and lower mold lines of the air outlet 120. Figure 2 and Figure 3In the illustrated embodiment, the structure of the air duct 411 can be extended by the extension section, which has the effect of slowing down and diffusing the airflow. By adjusting at different angles, the air supply range can be increased to meet the needs of different air supply distances, thereby achieving better cooling or heating effects and providing a better user experience.

[0073] It should be noted that the cross-sections of the first air guide plate 210, the second air guide plate 220 and the third air guide plate 230 are all flat. This is only an example. In some embodiments, the cross-sections of the three air guide plates can be in an arc or elliptical shape, which is conducive to reducing wind resistance. The specific shape can be selected according to actual application requirements.

[0074] Reference Figure 1 As shown, it can be understood that in the embodiment of the present invention, the first air guide plate 210 and the second air guide plate 220 cooperate to reveal or cover the air outlet 120. When the air outlet 120 is revealed, it is in an open state, and when the air outlet 120 is covered, it is in a closed state. When the air outlet 120 is in the closed state, the first air guide plate 210 and the second air guide plate 220 are set at an angle to each other, and the two cooperate to block the air outlet 120, thereby achieving the purpose of closing the air outlet 120.

[0075] In some embodiments, one end of the first air guide plate 210 has a first axis 211, and the first axis 211 is arranged adjacent to the first wall 121. When the first air guide plate 210 is able to swing around the first axis 211, the airflow flows through the upper wall of the air outlet 120 to the first air guide plate 210; one end of the second air guide plate 220 has a second axis 221, and the second axis 221 is located in the middle position of the air outlet 120, and the distance between the second axis 221 and the first axis 211 is less than or equal to the length of the first air guide plate 210, and the second air guide plate 220 is able to swing around the second axis 221.

[0076] It can be understood that when the first air guide plate 210 and the second air guide plate 220 swing to Figure 1 In the position shown, the end of the first air guide plate 210 away from the first axis 211 can abut against the second air guide plate 220, and the end of the second air guide plate 220 away from the second axis 221 can be adjacent to the second wall 122, so that the first air guide plate 210 and the second air guide plate 220 can block the air outlet 120.

[0077] Reference Figure 1As shown, one end of the third air guide plate 230 has a third axis 231, and the third axis 231 is arranged adjacent to the second wall surface 122. The bottom side of the face frame 130 is provided with an avoidance groove, and the third axis 231 is specifically arranged at the avoidance groove. When the air outlet 120 is closed, the third air guide plate 230 can be stored without affecting the closing of the second air guide plate 220. Specifically, the third air guide plate 230 can be connected to the bottom side of the face frame 130, and a recess 131 is arranged at the bottom wall of the face frame 130 near the third axis 231. When the air outlet 120 is closed, the third air guide plate 230 swings in a direction away from the second air guide plate 220, and can fit in the recess 131, so that the third air guide plate 230 does not protrude from the bottom surface of the face frame 130, which is conducive to maintaining the overall appearance flat. In some embodiments, the recess 131 can be a groove, a concave surface, or other structure formed on the bottom side of the face frame 130, depending on the actual situation.

[0078] It should be noted that the first axis 211 can be understood as the part where the driver drives the first air guide plate 210 to rotate, and can be a rotating shaft or other rotating connection structure. For example, the motor is connected to the position where the first axis 211 is located, so that the first air guide plate 210 can be driven to rotate around the first axis 211. The specific forms of the second axis 221 and the third axis 231 refer to the structure of the first axis 211 above, and are not described in detail.

[0079] It can be understood that the air guide assembly 200 of the embodiment of the present invention also includes a driver for driving the first air guide plate 210, the second air guide plate 220 and the third air guide plate 230 to rotate. In some embodiments, the first air guide plate 210, the second air guide plate 220 and the third air guide plate 230 are driven by independent drivers. Taking the motor as an example, the driver includes a first motor, a second motor and a third motor. The first motor is connected to the first axis 211, the second motor is connected to the second axis 221, and the third motor is connected to the third axis 231. That is, the angle of each air guide plate can be adjusted separately, for example Figure 2 In the illustrated embodiment, while the first air guide plate 210 remains stationary, the second air guide plate 220 and the third air guide plate 230 are driven to swing by the second motor and the third motor respectively, so that the air supply angle can be changed, and the first air guide plate 210 and the second air guide plate 220 can maintain an abutment state, which can provide a better air supply effect.

[0080] Of course, this is only an example. Considering that the swing angles of the second air guide plate 220 and the third air guide plate 230 are roughly the same, in some embodiments, the first air guide plate 210 is driven solely by the first motor, and the second air guide plate 220 and the third air guide plate 230 are driven synchronously by the second motor. This can reduce the number of motors, make control easier to implement, and reduce costs.

[0081] Reference Figure 1As shown, in the embodiment of the present invention, the first air guide plate 210 is provided with a plurality of first air dispersion holes 212, and the plurality of first air dispersion holes 212 are evenly distributed on the first air guide plate 210; the second air guide plate 220 is provided with a plurality of second air dispersion holes 222, and the plurality of second air dispersion holes 222 are evenly distributed on the second air guide plate 220, and the first air dispersion holes 212 and the second air dispersion holes 222 are both connected to the air outlet 120.

[0082] It can be understood that when the air-conditioning indoor unit 1000 is working and the first air guide plate 210 and the second air guide plate 220 close the air outlet 120, the air flow passing through the air outlet 120 will diffuse out from the first air dispersion hole 212 and the second air dispersion hole 222. In this process, the speed of the air flow will decrease, and the air flow will be dispersed and become soft, so that the air flow blowing into the room has a smaller and softer wind speed, achieving windless air outlet, making users more comfortable and having a better experience.

[0083] Reference Figures 4 to 7 As shown, the air conditioner indoor unit 1000 of the embodiment of the present invention can achieve different air supply angles and meet various air supply requirements by driving the first air guide plate 210, the second air guide plate 220 and the third air guide plate 230 to rotate during operation. The following description takes each air guide plate driven by an independent motor as an example.

[0084] Taking the horizontal direction as the reference direction, the rotation angle range of the first air guide plate 210, the second air guide plate 220 and the third air guide plate 230 relative to the reference direction is 0° to 135°, which has a wider air supply range. Specifically, in the embodiment, the three air guide plates are horizontally facing the front side at the 0° position, and the angle rotated in the clockwise direction at the 0° position is the rotation angle of the air guide plate. The rotation angles of the first air guide plate 210, the second air guide plate 220 and the third air guide plate 230 can be the same, for example, the rotation angles of the three air guide plates can be 30°, 60°, 90°, etc.; the rotation angles of the first air guide plate 210, the second air guide plate 220 and the third air guide plate 230 can also be different, for example, the rotation angle of the first air guide plate 210 is 30°, the rotation angle of the second air guide plate 220 is 50°, and the rotation angle of the third air guide plate 230 is 50°.

[0085] It should be noted that when the first air guide plate 210 and the second air guide plate 220 close the air outlet 120 , the third air guide plate 230 needs to be rotated to a position of 180° so as to fit against the bottom of the face frame 130 .

[0086] In some embodiments, the air conditioner indoor unit 1000 has a first state, a second state, a third state and a fourth state, wherein: Figure 4Shown is a schematic diagram of the first state. In the first state, the rotation angle range of the first air guide plate 210, the second air guide plate 220 and the third air guide plate 230 relative to the reference direction is 90° to 135°. The rotation angles of the first air guide plate 210, the second air guide plate 220 and the third air guide plate 230 may be different, and considering that the air outlet 120 needs to discharge air downward, the rotation angle of the first air guide plate 210 in the embodiment is maintained at 90°, and the second air guide plate 220 and the third air guide plate 230 can swing synchronously within the range of 90° to 135°, so that the first air guide plate 210 and the second air guide plate 220 can cooperate to form an extended section. At this time, the first air guide plate 210 and the second air guide plate 220 are in the first air guiding state, which has a better air supply effect and a better heating effect.

[0087] Reference Figure 4 As shown, taking the second air guide plate 220 as an example, the rotation angle α1 of the second air guide plate 220 relative to the reference direction can be 90°, 100°, 135°, etc. It can be understood that the air-conditioning indoor unit 1000 supplies air toward the bottom in the first state. The first state can be understood as bottom air supply, which is suitable for heating mode.

[0088] Reference Figure 5 As shown, in the second state, the rotation angle range of the first air guide plate 210, the second air guide plate 220 and the third air guide plate 230 relative to the reference direction is 60° to 90°. It can be understood that the first air guide plate 210 and the third air guide plate 230 respectively form extended sections, and the rotation angle of the second air guide plate 220 can meet the direction of the airflow, that is, swing along the wind direction to reduce wind resistance. For example, Figure 5 The rotation angle α2 of the second air guide plate 220 relative to the reference direction shown in the figure can be 60°, 70°, 90°, etc. It can be understood that the air-conditioning indoor unit 1000 supplies air obliquely downward in the second state. The second state can be understood as close-range air supply, which is suitable for heating mode.

[0089] Reference Figure 6 As shown, in the third state, the rotation angle range of the first air guide plate 210, the second air guide plate 220 and the third air guide plate 230 relative to the reference direction is 30° to 60°. It can be understood that, relative to the second state, the rotation angle of the first air guide plate 210, the second air guide plate 220 and the third air guide plate 230 is smaller, for example, Figure 6 The rotation angle α3 of the second air guide plate 220 relative to the reference direction shown in the figure can be 30°, 50°, 60°, etc. It can be understood that the air-conditioning indoor unit 1000 supplies air toward the front and obliquely downward in the third state, and the air supply angle is small. The third state can be understood as medium-distance air supply, which is suitable for cooling mode; it should be noted that at this time the third air guide plate 230 and the second air guide plate 220 can cooperate to form the second air guiding state, which has a better cooling effect.

[0090] Reference Figure 7 As shown, in the fourth state, the rotation angle range of the first air guide plate 210, the second air guide plate 220 and the third air guide plate 230 relative to the reference direction is 0° to 30°. It can be understood that, relative to the third state, the rotation angles of the first air guide plate 210, the second air guide plate 220 and the third air guide plate 230 are smaller, and it should be noted that in the fourth state, the three air guide plates are not limited to rotating in the clockwise direction, but can also rotate in the counterclockwise direction. For example, Figure 7 The rotation angle α4 of the second air guide plate 220 relative to the reference direction in the counterclockwise direction can be 5°, 10°, etc. It can be understood that the air conditioner indoor unit 1000 supplies air toward the front side or obliquely upward in the fourth state. The fourth state can be understood as long-distance air supply, which is suitable for cooling mode. It should be noted that Figure 7 FIG. 2 shows that the third air guide plate 230 and the second air guide plate 220 are in the second air guide state.

[0091] It can be understood that, in the heating mode, the air-conditioning indoor unit 1000 of the embodiment of the present invention controls the air guide component 200 to supply air in the first state and / or the second state to improve the heating effect; in the cooling mode, the air guide component 200 is controlled to supply air in the third state and / or the fourth state to improve the cooling effect, and different states are selected according to application requirements.

[0092] refer to Figures 8 to 12 The control method of the air conditioner indoor unit 1000 according to the embodiment of the present invention is described. The specific structure of the air conditioner indoor unit 1000 can be found in Figures 1 to 7 The illustrated embodiment will not be described in detail here, and the control method of the air conditioner indoor unit 1000 will be described below with a specific example.

[0093] Reference Figure 8 As shown, in some embodiments, the control method includes but is not limited to the following steps:

[0094] Step S100, according to the working mode of the air-conditioning indoor unit 1000, the air guide component 200 is controlled to operate so that when the air outlet 120 is opened, the air guide component 200 has a first air guiding state or a second air guiding state. The first air guiding state is that the first air guide plate 210 can be arranged in sequence with the second air guide plate 220 along the air flow direction of the air outlet for guiding air; the second air guiding state is that the third air guide plate 230 can be arranged in sequence with the second air guide plate 220 along the air flow direction of the air outlet for guiding air.

[0095] Combination Figures 1 to 3It can be understood that the control method of the embodiment of the present invention controls the air guide component 200 of the air-conditioning indoor unit 1000. Considering that the air guide component 200 needs to play an air-guiding role during the operation of the air-conditioning indoor unit 1000, and has different air supply requirements in different working modes, the control method steps require that the air-conditioning indoor unit 1000 is in operation, and the working mode of the air-conditioning indoor unit 1000 is obtained, and the operation of the air guide component 200 is controlled according to the obtained working mode.

[0096] When the air conditioner indoor unit 1000 is in operation, the air guide assembly 200 can be controlled according to instructions such as cooling mode and heating mode. For example, the user selects the cooling mode according to needs, and specifically operates through a remote control, mobile phone, tablet or other terminal to send control instructions.

[0097] It can be understood that, since the first air guide plate 210 is used as an extension of the upper mold line of the air outlet 120, the third air guide plate 230 is used as an extension of the lower mold line of the air outlet 120, and the first air guide plate 210 can be further controlled to cooperate with the second air guide plate 220 to further extend the upper mold line of the air outlet 120, for example Figure 2 In the embodiment shown, the first air guide plate 210 and the second air guide plate 220 are in the first air guide state; or the third air guide plate 230 is further controlled to cooperate with the second air guide plate 220 to further extend the lower profile of the air outlet 120, for example Figure 3 In the embodiment shown, the third air guide plate 230 and the second air guide plate 220 are in the second air guide state. The above structure can extend the structure of the air duct 411, slow down and expand the airflow, and adjust at different angles to increase the air supply range, meet the needs of different air supply distances, achieve better cooling or heating effects, and provide better user experience.

[0098] Reference Fig. 9 As shown, in some embodiments, the above step S100 specifically includes but is not limited to the following steps:

[0099] Step S110, when the air conditioner indoor unit 1000 is in the heating mode, the first air guide plate 210, the second air guide plate 220 and the third air guide plate 230 are controlled to swing within a first preset angle range;

[0100] Specifically, the first preset angle range can be understood as the default wind sweeping angle of the heating mode. After the user selects the heating mode, the air conditioner indoor unit 1000 will control the first air guide plate 210, the second air guide plate 220 and the third air guide plate 230 to swing within the first preset angle range.

[0101] In some embodiments, considering that the air conditioner indoor unit 1000 is suitable for heating mode operation in the first state and the second state, Figure 4 and Figure 5In the embodiment, it can be understood that the first preset angle range can be 60° to 135°, that is, the default sweeping angle of the heating mode swings between the bottom air supply angle and the close-range air supply angle.

[0102] Step S120, obtaining a difference between a set temperature and a detected temperature within a first preset time, and comparing the difference with a preset value;

[0103] Step S130, when the difference is less than or equal to the preset value, the first air guide plate 210, the second air guide plate 220 and the third air guide plate 230 are controlled to swing at the set angle of the global wind sweeping mode.

[0104] Taking into account that air supply at the bottom and at close range will cause the room's local temperature to rise faster, it is necessary to take into account the uniformity of the overall temperature distribution of the room. Therefore, in the control method of an embodiment of the present invention, when the room temperature is close to the set temperature, it is necessary to determine whether to switch to the full-area air sweeping mode to avoid local overheating.

[0105] It should be noted that the full-area air sweeping mode can be understood as the air sweeping angle of the air guide component 200 can cover bottom air supply, short-distance air supply, medium-distance air supply and long-distance air supply. The air supply range is wider, making the indoor temperature distribution more uniform and the user more comfortable.

[0106] It can be understood that when entering the heating mode, the air guide component 200 is controlled to swing according to the default wind sweeping angle. As the room temperature rises, the difference between the set temperature and the detected temperature is determined. Since the real-time temperature in the room will continue to change, the first preset time is used as the interval time in the embodiment, and the difference between the set temperature and the detected temperature is determined within the interval time. The difference is then compared with the preset value to determine whether it is satisfied to start the full-area wind sweeping mode.

[0107] The smaller the difference between the set temperature and the detected temperature, the closer the detected temperature is to the set temperature. When the difference is less than or equal to the preset value, the air guide assembly 200 is controlled to swing at the set angle of the global air sweeping mode. In addition, in the embodiment, the temperature of the room can be detected by a temperature sensor or other detection module to obtain the detected temperature.

[0108] To illustrate with a specific example, the set temperature is 25°C, the preset value is 2, the difference between the set temperature and the detected temperature within the interval time t is ΔE, and the interval time t can be 30s, 60s, etc. When the detected temperature is 24°C, the difference ΔE is 1, that is, the difference ΔE is less than the preset value, and the wind guide component 200 is controlled to enter the full-domain wind sweeping mode; when the detected temperature is 22°C, the difference ΔE is 3, that is, the difference ΔE is greater than the preset value, and the wind guide component 200 is controlled to continue to operate at the default wind sweeping angle. This is only an example, and the preset value can range from 0 to 2, which is selected according to the actual application requirements.

[0109] Reference Fig.10 As shown, in some embodiments, the above step S100 specifically includes but is not limited to the following steps:

[0110] Step S140, when the air conditioner indoor unit 1000 is in cooling mode, controlling the first air guide plate 210, the second air guide plate 220 and the third air guide plate 230 to swing within a second preset angle range;

[0111] Specifically, the second preset angle range can be understood as the default wind sweeping angle of the cooling mode. After the user selects the cooling mode, the air-conditioning indoor unit 1000 will control the first air guide plate 210, the second air guide plate 220 and the third air guide plate 230 to swing within the second preset angle range.

[0112] In some embodiments, considering that the air conditioner indoor unit 1000 is suitable for cooling mode operation in the third state and the fourth state, Figure 6 and Figure 7 In the embodiment, it can be understood that the second preset angle range can be 30° to 90°, that is, the default air sweeping angle of the cooling mode swings between the close-range air supply angle and the medium-range air supply angle.

[0113] Step S150, obtaining the difference between the set temperature and the detected temperature within the first preset time, and comparing the difference with the preset value;

[0114] Step S160, when the difference is greater than or equal to the preset value, the first air guide plate 210, the second air guide plate 220 and the third air guide plate 230 are controlled to swing at the set angle of the global wind sweeping mode.

[0115] It can be understood that in cooling mode, when the room temperature is close to the set temperature, by switching to the full-area wind sweeping mode, local overcooling can be avoided and the overall temperature distribution uniformity of the room can be taken into account.

[0116] Specifically, the smaller the difference between the set temperature and the detected temperature, the closer the detected temperature is to the set temperature. When the difference is greater than or equal to the preset value, the wind guide component 200 is controlled to swing at the set angle of the global wind sweeping mode. For example, the set temperature is 25°C, the preset value is -1, and when the detected temperature is 27°C, the difference ΔE is -2, that is, the difference ΔE is less than the preset value. At this time, the wind guide component 200 is controlled to continue to operate at the default wind sweeping angle; at the default wind sweeping angle, the temperature at close and medium distances decreases faster. When the detected temperature is 26°C, the difference ΔE is -1, that is, the difference ΔE is equal to the preset value. At this time, the wind guide component 200 is controlled to enter the global wind sweeping mode. It should be noted that in the embodiment, the difference ΔE is not an absolute value, that is, it can be a negative number. The preset value can range from -2 to 0, which is selected according to the actual application requirements.

[0117] It can be understood that in the control method of the embodiment of the present invention, priority is given to ensuring the rise and fall of temperature in both the heating mode and the cooling mode, and then switching to the full-area wind sweeping mode when the corresponding conditions are met, that is, focusing on increasing the air supply range, improving comfort through full-area air flow, and improving user experience.

[0118] In order to improve the air supply effect, the air guide component 200 is controlled in the embodiment to sweep the air in the order of the first state, the second state, the third state and the fourth state, that is, to meet the air supply requirements of bottom air supply, short-distance air supply, medium-distance air supply and long-distance air supply, so that the swing angle range of the air guide component 200 can cover different angles, can meet the air supply at different distances, and greatly improve the air supply range.

[0119] In addition, considering that the positions of the first air guide plate 210, the second air guide plate 220 and the third air guide plate 230 are different, Figures 1 to 3 It can be understood that the rotation angle range of each air guide plate is inconsistent, among which the rotation angle range of the second air guide plate 220 and the third air guide plate 230 is larger. In view of this, the control method of the embodiment of the present invention controls the air guide component 200 to sweep the air in the full-area sweeping mode, and passes through the first state, the second state, the third state and the fourth state in sequence, and stays in each state for a second preset time, so that the sweeping angle of each air guide plate can be close to the same, avoiding the problem of any of the air guide plates rotating too fast or too slow, thereby improving the sweeping effect.

[0120] Reference Fig.11 Specifically, taking the cooling mode as an example, the control method includes but is not limited to the following steps:

[0121] Step S141, when the air conditioner indoor unit 1000 is in cooling mode, the first air guide plate 210, the second air guide plate 220 and the third air guide plate 230 are controlled to swing at a default wind sweeping angle;

[0122] Step S151, obtaining the difference between the set temperature and the detected temperature within the interval time, and comparing the difference with the preset value;

[0123] Step S161, when the difference is greater than or equal to the preset value, control the first air guide plate 210, the second air guide plate 220 and the third air guide plate 230 to swing, and pass through the first state, the second state, the third state and the fourth state in sequence, and stay in each state for a second preset time.

[0124] Reference Fig.12 As shown, Fig.12 It is understood that after the air conditioner indoor unit 1000 is turned on, it is necessary to determine whether the global wind sweeping mode is turned on. When the user turns on the global wind sweeping mode, the air guide component 200 is directly controlled to operate in the global wind sweeping mode; when the global wind sweeping mode is not turned on, the current working mode is determined, and then the corresponding steps are performed according to the cooling mode or the heating mode. For details, see Figures 8 to 11 The embodiment shown.
