[0066] The term "and / or" describes an association between objects, indicating that three relationships can exist. For example, A and / or B means: A or B, or A and B.

[0067] It should be noted that, unless otherwise specified, the embodiments and features described in the present disclosure can be combined with each other.

[0068] like FIGS. 1-29 As shown, this disclosure provides a cabinet-type air conditioner indoor unit, which can also be called an indoor unit, air conditioner indoor unit, floor-standing indoor unit, floor-standing air conditioner indoor unit, or air conditioner indoor unit, etc.

[0069] Optionally, combined FIGS. 1-29As shown, the indoor unit of the air conditioner includes a housing 1, a heat exchanger 2, and a fan 21. The housing 1 has an air inlet and a front air outlet 101. The housing 1 has a first air duct 41 that communicates with the air inlet and the front air outlet 101. The fan 21 and the heat exchanger 2 are both located inside the housing 1. The fan 21 drives the indoor air drawn in through the air inlet to exchange heat with the heat exchanger 2 to obtain heat exchange air, and drives the heat exchange air to flow through the first air duct 41 and the front air outlet 101 in sequence and then out.

[0070] The air conditioner indoor unit provided in this embodiment can obtain heat exchange air after the airflow flowing in through the air inlet exchanges heat with the heat exchanger 2. The heat exchange air can flow out from the front air outlet 101 under the drive of the fan 21, so that the air conditioner indoor unit can vent air from the front, thereby regulating the indoor temperature.

[0071] Optionally, the fan 21 is a cross-flow fan 21. The axis of the cross-flow fan 21 extends in the vertical direction, that is, the axis of the cross-flow fan 21 extends in the up-down direction.

[0072] Optionally, the heat exchanger 2 and the fan 21 are located between the inlet end of the first air duct 41 and the air inlet.

[0073] Optionally, the heat exchanger 2 and the fan 21 are arranged sequentially from back to front, so that the airflow flowing in from the air inlet flows through the heat exchanger 2 and the fan 21 in sequence.

[0074] Optionally, the fan 21 is placed close to the inlet of the first air duct 41 so that more airflow from the fan 21 can flow into the first air duct 41.

[0075] Optionally, the heat exchanger 2 is arc-shaped and partially surrounds the fan 21, which can increase the heat exchange area between the airflow and the heat exchanger 2, thereby improving the heat exchange efficiency.

[0076] Optionally, the housing 1 is further provided with a first side air outlet 102, and a first air duct 41 is connected between the air inlet and the first side air outlet 102.

[0077] Optionally, such as FIGS. 1-25 As shown, the indoor unit of the air conditioner also includes an air guide 3, which is retractably located at the front air outlet 101. When the air guide 3 is extended, the heat exchange air is sent out through the gap between the inner wall of the front air outlet 101 and the outer wall of the air guide 3; when the air guide 3 is retracted, the heat exchange air front air outlet 101 is closed, and the heat exchange air can be sent out from the first side air outlet 102.

[0078] The air conditioner indoor unit provided in this application has a front air outlet 101 and a first side air outlet 102 both connected to a first air duct 41. Furthermore, a retractable air guide 3 is provided at the front air outlet 101. When the air guide 3 extends, the heat exchange air in the first air duct 41 can be delivered through the gap between the inner wall of the front air outlet 101 and the outer wall of the air guide 3, thus realizing the air delivery mode of the front air outlet 101. FIG. 6-1 As shown; when the air guide 3 retracts, it completely or partially closes the front air outlet 101, and the heat exchange air from the first air duct 41 is sent out through the first side air outlet 102, thus realizing the side air outlet air supply mode, as shown. FIG. 5-1 As shown.

[0079] As can be seen, the air conditioner indoor unit provided in this embodiment can selectively deliver air from the front air outlet 101 or the first side air outlet 102 according to the user's needs.

[0080] Optionally, the front air outlet 101 is located on the front panel of the housing 1, and the first side air outlet 102 is located on the side of the front air outlet 101. In this way, the air supply direction of the front air outlet 101 is different from that of the side air outlet.

[0081] Optionally, the front air outlet 101 is located at a relatively high position in the housing 1, and the first side air outlet 102 is located at approximately the same height as the front air outlet 101.

[0082] Optionally, the air guide 3 includes a first air guide wall 31, and when the air guide 3 is retracted, the first air guide wall 31 is located inside the housing 1, wherein at least a portion of the first air guide wall 31 is arc-shaped.

[0083] At least a portion of the outer wall of the first guide wall 31 is arc-shaped, such as FIG. 8 and FIG. 9 As shown. The arc-shaped first air guide wall 31 improves the air guiding effect in the air supply mode of the front air outlet 101. Optionally, the first air guide wall 31 is a complete air guiding structure without an air outlet. In this way, when the air guide body 3 extends, the heat exchange air is sent out from the gap between the front air outlet 101 and the outer wall of the first air guide wall 31.

[0084] Optionally, the first air guide wall 31 is open, and the air guide body 3 further includes a first air guide cover 32 that closes the opening of the first air guide wall 31. FIG. 8 and FIG. 9 As shown.

[0085] Optionally, the first air guide wall 31 includes an air guide front end 311 near the front air outlet 101 and an air guide rear end 312 connected to the air guide front end 311 and away from the front air outlet 101. The air guide rear end 312 includes a first rear air guide position 3121 connected to the air guide front end 311 and a second rear air guide position 3122 away from the air guide front end 311. The distance between the air guide rear end 312 and the inner wall of the first air duct 41 gradually increases from the first rear air guide position 3121 to the second rear air guide position 3122.

[0086] Optionally, the air guide front end 311 is the portion of the first air guide wall 31 near the front air outlet 101, such as... FIG. 11 As shown; the rear end 312 of the air guide is the portion of the first air guide wall 31 that is furthest from the front air outlet 101, as... FIG. 12 As shown. Optionally, the first air guide wall 31 is divided along its depth direction, with the extension depth of the air guide front end 311 being less than the extension depth of the air guide rear end 312. Optionally, the extension depth of the air guide front end 311 accounts for 1 / 5 to 1 / 3 of the total depth of the first air guide wall 31, and the remaining part is the air guide rear end 312. Optionally, the air guide front end 311 and the air guide rear end 312 are integrally formed.

[0087] Alternatively, the angle between the external tangent of each part of the air guide rear end 312 and the vertical direction is less than or equal to a first included angle threshold, while the angle between the external tangent of each part of the air guide front end 311 and the vertical direction is greater than the first included angle threshold. Optionally, the first included angle threshold is 60° to 65°. Alternatively, it can also be understood that the first air guide wall 31 is divided at the point where the angle between the external tangent of the first air guide wall 31 and the vertical direction is the first included angle threshold, thus obtaining the air guide front end 311 and the air guide rear end 312.

[0088] Optionally, the front end of the air guide 311 is arc-shaped and has a relatively large degree of curvature; the rear end of the air guide 312 can also be arc-shaped and have a relatively small degree of curvature.

[0089] The two ends of the air guide rear end 312 are the first rear air guide position 3121 and the second rear air guide position 3122, respectively. The first rear air guide position 3121 is directly connected to the air guide front end 311, and the second rear air guide position 3122 is the position furthest from the air guide front end 311. When the air guide body 3 is in the retracted state, the distance between the air guide rear end 312 and the inner wall of the first air duct 41 gradually increases from the first rear air guide position 3121 to the second rear air guide position 3122. FIG. 12 As shown. In this way, when the air guide 3 is in the retracted state, the air delivery effect of the first air duct 41 through the first side air outlet 102 is improved. At the same time, when the air guide 3 is extended, the obstruction effect of the air guide 3 on the front air outlet 101 is reduced, and the air delivery effect of the front air outlet 101 is improved.

[0090] Optionally, the rear end of the air guide 312 is bowl-shaped, including a bottom wall 3123 and a side wall 3124 of the bowl-shaped body, wherein the extension depth of the bottom wall 3123 of the bowl-shaped body is h1, the extension depth of the side wall 3124 of the bowl-shaped body is h2, and h1 < h2.

[0091] The air guide rear end 312 is roughly bowl-shaped, including a bowl-shaped bottom wall 3123 and a bowl-shaped side wall 3124 disposed on the side of the bowl-shaped bottom wall 3123. It can be understood that the bowl-shaped bottom wall 3123 is roughly vertical, or the angle formed between the bowl-shaped bottom wall 3123 and the vertical direction is small, such as... FIG. 13 As shown; the bowl-shaped body sidewall 3124 has a relatively large degree of curvature, forming a large angle with the vertical direction, such as... FIG. 14 As shown.

[0092] Optionally, the angle between the external tangent of each part of the bowl-shaped bottom wall 3123 and the vertical direction is less than or equal to a second included angle threshold, and the angle between the external tangent of each part of the bowl-shaped side wall 3124 and the vertical direction is greater than the second included angle threshold. Optionally, the second included angle threshold is 25° to 30°. Alternatively, it can be understood that at the point where the angle between the external tangent of the air guide rear end 312 and the vertical direction is the second included angle threshold, the air guide rear end 312 is divided to obtain the bowl-shaped bottom wall 3123 and the bowl-shaped side wall 3124. Optionally, the bowl-shaped bottom wall 3123 and the bowl-shaped side wall 3124 are integrally formed.

[0093] In this embodiment of the disclosure, the extension depth of the bottom wall 3123 of the bowl-shaped body is h1, the extension depth of the side wall 3124 of the bowl-shaped body is h2, and h1 < h2. FIG. 13 and FIG. 14 As shown, the bottom wall 3123 of the bowl-shaped body has a relatively shallow extension depth and a relatively gentle overall shape. This allows the airflow within the first air duct 41 to have minimal contact with the bottom wall 3123 when the air guide 3 is extended, reducing the wind-blocking effect of the bottom wall 3123 at the front air outlet 101. FIG. 6-1 As shown. Furthermore, when the air guide 3 is in the retracted state, the relatively gentle bottom wall 3123 of the bowl-shaped body facilitates the air in the first air duct 41 being sent out through the first side air outlet 102. Optionally, 2h1 < h2 < 4h1. For example, h2 can be 3 times h1.

[0094] Optionally, the width of the bottom wall 3123 of the bowl-shaped body is k1, and the width of the side wall 3124 of the bowl-shaped body is k2, where h1 / k1 < h2 / k2. Optionally, k1 > k2, so that the bottom wall 3123 of the bowl-shaped body has a larger width and a smaller extension depth, while the side wall 3124 of the bowl-shaped body has a smaller width and a larger extension depth.

[0095] It is understandable that the first guide wall 31 is divided into 50 / 50 sections along the vertical direction, such as... FIG. 8 As shown, t is the dividing line at 1 / 2. The width of the bottom wall 3123 of the bowl-shaped body is the width of the bottom wall 3123 of the bowl-shaped body in the divided 1 / 2, and the width of the side wall 3124 of the bowl-shaped body is the width of the side wall 3124 of the bowl-shaped body in the divided 1 / 2.

[0096] Optionally, the angle between the outer tangent of the first rear air guide position 3121 of the air guide rear end 312 and the horizontal plane is a1, where a1 < 40°. Optionally, the value of a1 can be 35°, 30° or 25°.

[0097] Optionally, the angle between the outer tangent of the second rear air guide position 3122 at the rear end of the air guide 312 and the horizontal plane is α2, where α2 > 30°. Optionally, the value of α2 can be 65°, 70°, 75°, 80°, or 85°. FIG. 15 As shown.

[0098] Optionally, the first side air outlet 102 is disposed on the side of the front air outlet 101, and the height of the first side air outlet 102 is g1, and the height of the front air outlet 101 is g2, wherein g1≥g2.

[0099] like FIG. 2 and FIG. 3 As shown, when the air guide 3 retracts, the heat exchange air in the first air duct 41 is sent out through the first side air outlet 102. At this time, the first side air outlet 102 also has a pressure relief function to prevent the air from being trapped in the first air duct 41 when the air guide 3 retracts.

[0100] In this embodiment, the height of the first side air outlet 102 is approximately the same as the height of the front air outlet 101, and the height of the first side air outlet 102 is greater than or equal to the height of the front air outlet 101. In this way, the air delivery effect of the first side air outlet 102 is improved when the air guide 3 is retracted.

[0101] Optionally, the housing 1 is further provided with a second side air outlet 103, and a second air duct 42 connected to the second side air outlet 103 is provided inside the housing 1. The second side air outlet 103 is located at the lower part of the first side air outlet 102, the second air duct 42 is located at the lower part of the first air duct 41, and an air duct partition 104 is provided between the first air duct 41 and the second air duct 42.

[0102] The second side air outlet 103 is disposed adjacent to the first side air outlet 102, and is disposed below the first side air outlet 102, such as FIG. 2As shown, the duct partition 104 separates the first duct 41 and the second duct 42. Optionally, the indoor unit of the air conditioner is equipped with a cross-flow fan that simultaneously supplies air to both the first duct 41 and the second duct 42.

[0103] Optionally, there are two first side air outlets 102, which are respectively located on both sides of the front air outlet 101. Optionally, there are two second side air outlets 103, which are respectively located at the lower part of the first side air outlets 102.

[0104] Optionally, the air guide 3 includes a maximum extended position where it is fully extended from the front air outlet 101, a retracted position where it is retracted to the front air outlet 101, and an intermediate extended position between the retracted position and the maximum extended position. The air volume of the front air outlet 101 when the air guide 3 is in the maximum extended position is greater than the air volume of the front air outlet when the air guide 3 is in the intermediate extended position.

[0105] like FIG. 27 As shown, FIG. 27 Figure C shows the airflow from the front air outlet 101 when the air guide 3 is in its maximum extended position. FIG. 27 Figure d shows the airflow from the first side outlet 102 when the air guide 3 is in the retracted position; FIG. 27 Figure a or b shows the airflow from the front air outlet 101 when the air guide 3 is in the middle extended position.

[0106] from FIG. 27 As can be seen, when the air guide 3 is at its maximum extension position, the obstruction to the front air outlet 101 is minimal, and the airflow from the front air outlet 101 is maximized. When the air guide 3 is at its middle extension position, it creates a relatively large obstruction to the front air outlet 101, and correspondingly, the airflow from the front air outlet 101 decreases. Therefore, the air conditioning indoor unit provided in this embodiment can adjust the airflow from the front air outlet 101 by adjusting the extension position of the air guide 3.

[0107] Optionally, when the air guide 3 is in its maximum extended position, the air delivery angle formed by the front air outlet 101 is the first air delivery angle, and when the air guide 3 is in its middle extended position, the air delivery angle formed by the front air outlet 101 is the second air delivery angle, and the first air delivery angle is smaller than the second air delivery angle.

[0108] When the air guide 3 extends to its maximum position, it is in its maximum extended position. At this time, the inner wall of the first air guide wall 31 of the air guide 3 has a relatively small guiding effect on the heat exchange air in the first air duct 41, and the front air outlet 101 forms a roughly forward air delivery direction, such as... FIG. 16 and FIG. 27As shown in Figure c; when the air guide 3 is in the middle extended position, the air guide 3 is not fully extended. The inner wall of the first air guide wall 31 of the air guide 3 exerts a certain compression and guiding effect on the heat exchange air in the first air duct 41, so that the air in the first air duct 41 is guided by the inner wall of the first air guide wall 31 and then sent out from the front air outlet 101, forming an air delivery direction inclined to both sides, as shown in Figure c. FIG. 17 and FIG. 27 As shown in a and b.

[0109] In the air conditioning indoor unit provided in this embodiment, when the air guide 3 is in its maximum extended position, the air delivery angle formed by the front air outlet 101 is a first air delivery angle; when the air guide 3 is in its middle extended position, the air delivery angle formed by the front air outlet 101 is a second air delivery angle, and the first air delivery angle is smaller than the second air delivery angle. It can be seen that the air delivery angle of the front air outlet 101 can be adjusted by adjusting the extended position of the air guide 3 at the front outlet. Furthermore, when the air guide 3 is in its retracted position, the air from the first air duct 41 is delivered from the first side air outlet 102. That is, the air conditioning indoor unit provided in this embodiment can adjust the airflow direction of the front air outlet 101 by adjusting the extended position of the air guide 3, thereby improving the diversity of the upper air delivery direction of the air conditioning indoor unit.

[0110] Optionally, when the air guide 3 is in its maximum extended position, the air velocity at the front air outlet 101 is relatively low, resulting in a shorter air delivery distance; when the air guide 3 is in its middle extended position, the air velocity at the front air outlet 101 is relatively high, resulting in a longer air delivery distance. That is, the air conditioning indoor unit provided in this embodiment can adjust the air velocity at the front air outlet 101 by adjusting the extended position of the air guide 3.

[0111] As can be seen, the air conditioning indoor unit provided in this embodiment can adjust the air volume, air speed and air direction by adjusting the extension position of the air guide 3, thereby improving the diversity of the air outlet direction of the upper air supply of the air conditioning indoor unit.

[0112] Optionally, when the air guide 3 is in the maximum extended position, the distance between the front end of the air guide 3 and the housing 1 is r1, where 50mm≤r1≤70mm.

[0113] When the air guide 3 is in its maximum extended position, a certain horizontal distance r1 is formed between the front end of the air guide 3 and the housing 1. Optionally, 50mm ≤ r1 ≤ 70mm. This allows the air guide 3 to fully extend from the front air outlet 101 without creating a large distance between it and the front panel of the housing 1. Optionally, r1 can be 50mm, 53mm, 55mm, 58mm, 60mm, 62mm, 65mm, 67mm, or 70mm. FIG. 18 As shown.

[0114] Optionally, when the air guide 3 is in its maximum extended position, the perpendicular line passing through point Q1 on the inner wall of the front air outlet 101 intersects the inner wall of the air guide 3 at point Q2, and the distance between Q1 and Q2 is r2, where r2 ≥ r1.

[0115] like FIG. 18 As shown, the gap formed between Q1 and Q2 can be the air outlet gap when the air guide 3 is in its maximum extended position. In this embodiment, r2 ≥ r1, thus increasing the width of the air outlet gap when the air guide 3 is in its maximum extended position, and improving the air delivery effect of the front air outlet 101. Optionally, r2 can be 60mm, 63mm, 65mm, 68mm, 70mm, 72mm, 75mm, 77mm, 80mm, 85mm, 90mm, 95mm, or 100mm. Optionally, r2 < 1.5r1.

[0116] Optionally, the width of the first air guide wall 31 is s1, and the extension depth of the first air guide wall 31 is h, where s1 > h.

[0117] In this embodiment of the disclosure, the width s1 of the first air guide wall 31 is greater than the extension depth h of the first air guide wall 31, such as... FIG. 19 As shown, this reduces the volume occupied by the air guide 3 in the thickness direction of the indoor unit of the air conditioner, so that the air guide 3 can have a good air guiding effect with a small extension distance.

[0118] Optionally, 3h≤s1≤5h.

[0119] Optionally, 230mm≤s1≤280mm. s1 can be 230mm, 235mm, 240mm, 245mm, 250mm, 255mm, 260mm, 265mm, 270mm, 275mm or 280mm.

[0120] Optionally, 65mm ≤ h ≤ 80mm. h can be 65mm, 68mm, 70mm, 72mm, 75mm, 77mm or 80mm.

[0121] Optionally, when the air guide 3 is in the retracted position, the distance between the air guide 3 and the front air outlet 101 is r3, where 10mm≤r3≤15mm.

[0122] In this embodiment of the disclosure, when the air guide 3 is in the retracted position to the front air outlet 101, there is still a certain distance r3 between the air guide 3 and the front air outlet 101, such as... FIG. 19 As shown, when the air guide 3 is in the retracted position, there can be a gentle breeze at the front air outlet 101.

[0123] Optionally, 10mm≤r3≤15mm, where r3 can be 10mm, 11mm, 12mm, 13mm, 14mm or 15mm.

[0124] Optionally, such as FIGS. 20-25 As shown, the indoor unit of the air conditioner also includes a drive assembly 5.

[0125] The drive assembly 5 is connected to the air guide 3 and is used to drive the air guide 3 to extend and retract.

[0126] The air guide 3 extends or retracts in the front-to-back direction under the drive of the drive component 5, and can extend out of the front air outlet 101 or retract into the front air outlet 101.

[0127] Optionally, the first guide wall 31 of the air guide body 3 is provided with a first track plate 53, and the first track plate 53 is provided with a first rack 532; the drive assembly 5 includes a first motor 51 and a first gear 52 drivenly connected to the first motor 51, wherein the first gear 52 meshes with the first rack 532 to drive the air guide body 3 to extend and retract.

[0128] The drive assembly 5 includes a first motor 51 and a first gear 52. The first gear 52 rotates under the drive of the first motor 51. The first guide wall 31 is provided with a first track plate 53, which is fixedly installed on the first guide wall 31. The first track plate 53 is provided with a first rack 532. The first gear 52 meshes with the first rack 532, driving the guide body 3 to move in the front-back direction, so that the guide body 3 can extend or retract.

[0129] Optionally, the first track plate 53 includes a flat first track plate surface 531, wherein a first rack 532 is disposed on the first track plate surface 531.

[0130] The first track plate 53 has a flat surface 531, and the first rack 532 is disposed on the flat surface 531. This improves the effect of the drive assembly 5 in driving the air guide 3 to move in the front-to-back direction.

[0131] Optionally, the first air guide wall 31 includes an upper wall surface position 313 at the upper end and a lower wall surface position 314 at the lower end, wherein both the upper wall surface position 313 and the lower wall surface position 314 are provided with a drive assembly 5.

[0132] The upper wall position 313 and the lower wall position 314 of the first air guide wall 31 are both provided with driving components 5. In this way, the air guide body 3 moves under the drive of the two sets of driving components 5, which improves the movement stability and accuracy of the air guide body 3.

[0133] Optionally, drive components 5 are provided on both the left and right sides of the first air guide wall 31. In this way, by setting two sets of drive components 5 on the left and right sides of the first air guide wall 31 respectively, the movement accuracy of the air guide body 3 is improved.

[0134] Optionally, the indoor unit of the air conditioner also includes a mounting frame 54. The mounting frame 54 is disposed within the housing 1 and includes a first frame segment 541 disposed at the front air outlet 101, wherein the drive assembly 5 is mounted on the first frame segment 541.

[0135] The mounting frame 54 is installed inside the housing 1 of the indoor unit of the air conditioner, and functional components such as the fan can be fixedly installed on the mounting frame 54. The first frame segment 541 of the mounting frame 54 is located near the front air outlet 101, and the drive assembly 5 is installed on the first frame segment 541, which improves the installation stability of the drive assembly 5.

[0136] Optionally, the first frame segment 541 includes a frame front end near the front air outlet 101, and the first air duct 41 includes an air duct front end near the front air outlet 101, wherein the frame front end is wrapped around the outside of the air duct front end, and the frame front end is disposed to avoid the air vent. FIG. 21 and FIG. 25 As shown.

[0137] Optionally, the first skeleton segment 541 is provided with a sliding groove 542, wherein the first track plate 53 can slide back and forth within the sliding groove 542.

[0138] like FIG. 24 and FIG. 25 As shown, the first frame segment 541 has a vertically penetrating slide groove 542. The first track plate 53 can move back and forth in the slide groove 542 under the driving action of the drive component 5, thereby driving the air guide 3 to extend or retract.

[0139] Optionally, there can be multiple chutes 542, and the number of chutes 542 is determined according to the number and location of the first track plates 53.

[0140] Optionally, the slide groove 542 is provided with raised flanges 543 on both sides, wherein the first track plate 53 includes a snap-fit ​​protrusion 533 that snaps onto the outside of the flange 543.

[0141] like FIG. 25 As shown, both sides of the slide groove 542 are provided with upwardly protruding flanges 543, and the lower part of the first track plate 53 is provided with a locking protrusion 533 that can be locked onto the outer side of the flanges 543 and move under the support and abutment of the flanges 543. In this way, the movement stability of the first track plate 53 is improved.

[0142] Optionally, such as FIGS. 4-1-7-3 as well asFIGS. 27-28 As shown, the side wall of the first air duct 41 is provided with an air vent 6, which connects the interior and exterior of the first air duct 41.

[0143] In this embodiment, the first air duct 41 has a vent 6, which reduces the air outlet area of ​​the current air outlet 101, increases the air resistance within the first air duct 41, and allows the heat exchange air within the first air duct 41 to flow out through the vent 6 when the air pressure increases. FIG. 7-1 and 7-2 As shown, this avoids the accumulation of heat exchange air in the first air duct 41, which can generate eddies. This can prevent excessive back pressure in the first air duct 41, thereby ensuring the working efficiency of the fan 21, reducing noise, ensuring the uniformity of air velocity on the surface of the heat exchanger 2, improving heat exchange efficiency, preventing the fan 21 from surging, improving the reliability of air conditioning operation, and thus improving the user experience.

[0144] Optionally, the air outlet area of ​​the front air outlet 101 is adjustable. When the air outlet area of ​​the front air outlet 101 is less than or equal to a preset area, or when the air pressure in the first air duct 41 is greater than a pressure threshold, some of the heat exchange air in the first air duct 41 can flow out through the vent 6. This can prevent airflow accumulation in the first air duct 41, which could cause the fan 21 to surge, reduce noise, and thus improve the user experience.

[0145] Optionally, along the flow direction of the airflow in the first air duct, the flow area of ​​the first air duct gradually increases so that the heat exchange air in the first air duct 41 can be accelerated and then diffused, which can buffer instantaneous pressure pulses, reduce the risk of surge of the fan 21, and can cooperate with the air outlet and vent.

[0146] Optionally, such as FIG. 4-2 As shown, the first air duct 41 includes a first air duct section 401 and a second air duct section 402 connected sequentially along the airflow direction. The second air duct section 402 has a front air outlet 101 at one end away from the first air duct section 401. The flow area of ​​the first air duct section 401 is smaller than the flow area of ​​the second air duct section 402. The vent 6 is located on the side wall of the second air duct section 402.

[0147] In this embodiment, the vent 6 is positioned close to the front air outlet 101. This allows the airflow accumulated at the front air outlet 101 to be discharged through the vent 6 when the air outlet area of ​​the front air outlet 101 decreases, preventing airflow backflow or accumulation within the first air duct 41, ensuring smooth airflow and volume, and reducing noise. Furthermore, the flow area of ​​the second air duct section 402 is larger than that of the first air duct section 401, allowing the heat exchange air within the first air duct 41 to first accelerate and then diffuse, buffering instantaneous pressure pulses and reducing the risk of surge in the fan 21.

[0148] Optionally, such as FIG. 4-4As shown, the distance L1 between the foremost part of the vent 6 and the front air outlet 101 ranges from 15mm to 30mm.

[0149] In this embodiment, the distance L1 between the foremost point of the vent 6 and the front air outlet 101 is maintained at 15mm to 30mm. This allows the airflow to escape from the vent 6 via the shortest path and with the lowest resistance when the air outlet area of ​​the front air outlet 101 is reduced or closed. This reduces the risk of overload on the fan 21. Simultaneously, a distance L1 greater than 15mm between the foremost point of the vent 6 and the front air outlet 101 prevents airflow short-circuiting due to their proximity. A distance L1 less than 30mm ensures that the vent 6 remains within the diffusion zone of the second duct section 402, balancing noise reduction and structural compactness.

[0150] For example, the distance L1 between the foremost point of the vent 6 and the front air outlet 101 can be 15mm, 16mm, 17mm, 18mm, 19mm, 20mm, 22mm, 25mm, or 30mm, etc.

[0151] Optionally, such as FIG. 4-4 As shown, the distance L2 between the rear end of the vent 6 and the rear end of the first air duct 41 ranges from 40mm to 60mm.

[0152] In this embodiment, with a distance of 40mm to 60mm between the rear end of the vent 6 and the rear end of the first air duct 41, the vent 6 is located just outside the "vortex dead zone" upstream of the end of the first air duct 41. This avoids the turbulent core area caused by the wake of the fan 21, preventing the exhaust airflow from carrying vortex noise and reducing noise. It also maintains a sufficient upstream pressure stabilization section, allowing the vent 6 to still utilize the main kinetic energy during pressure relief, ensuring stable bypass ventilation and faster pressure drop. Simultaneously, a distance L2 greater than 40mm between the rear end of the vent 6 and the rear end of the first air duct 41 ensures sufficient structural assembly margin, while a distance L2 less than 60mm avoids increasing the overall unit depth, maintaining a compact structure for the indoor air conditioning unit.

[0153] For example, the distance L2 between the rear end of the vent 6 and the rear end of the first air duct 41 is 40mm, 42mm, 45mm, 47mm, 50mm, 52mm, 56mm, 60mm, etc.

[0154] Optionally, the length of the vent 6 along the height direction ranges from 200mm to 300mm; and / or, the width of the vent 6 along the front-to-back direction ranges from 40mm to 60mm.

[0155] In this embodiment, the height of the vent 6 is between 200mm and 300mm, ensuring it matches the effective axial length of the fan 21. This allows for uniform pressure relief across the entire height range, causing the static pressure at each cross-section of the fan 21 to decrease synchronously, preventing blade vibration caused by localized high pressure, and reducing overall machine noise. The width of the vent 6 along the front-to-back direction is between 40mm and 60mm, ensuring the ratio of the vent 6 area to the sidewall area of ​​the second air duct section 402. This prevents secondary noise and condensation risks from high-speed jets, while also ensuring effective pressure relief and airflow.

[0156] For example, the length of the vent 6 along the height direction is 200mm, 220mm, 240mm, 250mm, 270mm, 280mm, 300mm, etc.

[0157] For example, the width of the vent 6 along the front-to-back direction is 40mm, 45mm, 50mm, 55mm or 60mm, etc.

[0158] Optionally, such as FIGS. 4-1-7-3 As shown, an exhaust channel 64 is provided inside the housing 1. The exhaust channel 64 has a first side air outlet 102, which is connected to the outside. The exhaust channel 64 is located on one side of the first air duct 41, and the vent 6 connects the exhaust channel 64 and the first air duct 41.

[0159] In this embodiment of the present disclosure, the indoor unit of the air conditioner can also discharge air through the first side air outlet 102, which improves the air discharge direction of the indoor unit of the air conditioner and enables multi-dimensional air supply. Furthermore, the first side air outlet 102 can also cooperate with the front air outlet 101 to form various forms of air discharge, such as environmentally friendly air, thereby improving the uniformity of indoor temperature.

[0160] It is understood that the exhaust channel may not be connected to the first side air outlet. That is to say, the vent is not connected to the first side air outlet. The vent can flow out of the first air duct and into the housing, and then be discharged through the gap in the housing. The configuration method that enables the heat exchange air in the first air duct to flow out and achieve pressure relief is an optional embodiment of this application.

[0161] Optionally, the ratio of the minimum flow area of ​​the exhaust passage 64 to the ventilation area of ​​the vent 6 (that is, the opening area of ​​the vent) is in the range of 2:1 to 5:1.

[0162] In this embodiment, the flow area of ​​the exhaust channel 64 is larger than the ventilation area of ​​the vent 6. This means that when the high-speed airflow from the vent 6 reaches the exhaust channel, its velocity decreases due to the increased flow area, and the dynamic pressure is efficiently converted into static pressure, thus avoiding outlet jet noise. The ratio of the minimum flow area of ​​the exhaust channel 64 to the maximum ventilation area of ​​the vent 6 is less than 5:1, preventing excessive expansion of the exhaust channel 64 and the generation of eddies. The ratio of the minimum flow area of ​​the exhaust channel 64 to the ventilation area of ​​the vent 6 is greater than 2:1, ensuring sufficient diffusion length and reducing airflow turbulence and noise.

[0163] For example, the ratio of the minimum flow area of ​​the exhaust channel 64 to the ventilation area of ​​the vent 6 can be 2:1, 3:1, 4:1, 5:1, etc.

[0164] Optionally, ventilation openings 6 are provided on both sides of the width direction of the first air duct 41, so that the pressure of the first air duct 41 can be relieved from both sides of the first air duct 41, thereby improving the uniformity of airflow within the first air duct 41.

[0165] Optionally, exhaust channels 64 are provided on both sides of the width direction of the first air duct 41, and each exhaust channel 64 is provided with a first side air outlet 102. In this way, the heat exchange air in the first air duct 41 can flow from the air inlets 6 on both sides of the width direction into the exhaust channel 64, and then be discharged through the first side air outlet 102 on both sides to achieve side air outlet.

[0166] Optionally, such as FIG. 27 and FIG. 28 As shown, the housing 1 includes an air duct component 4, which includes two first air duct plates 411 and an annular air duct plate 413 arranged opposite to each other. The annular air duct plate 413 is located between the two first air duct plates 411, and an annular air duct 4131 is defined inside the annular air duct plate 413. The outlet end of the annular air duct 4131 corresponds to the front air outlet 101. The first air duct 41 includes the annular air duct 4131.

[0167] In this embodiment of the present disclosure, the air duct near the front air outlet 101 in the first air duct 41 is annular, so that the front air outlet 101 can also achieve annular air outlet, which further improves the air outlet form and air outlet range of the front air outlet 101.

[0168] Optionally, such as FIG. 21 As shown, the vent 6 includes a first vent 61, which penetrates the annular air duct plate 413 and the first air duct plate 411. This brings the first vent 61 closer to the front air outlet 101, enabling efficient pressure relief of the first air duct 41, preventing airflow backflow, reducing air pressure within the first air duct 41, and lowering noise. Furthermore, the annular air duct 4131 increases the flow area of ​​the heat exchange air within the first air duct 41 and also increases the pressure relief area of ​​the first vent 61, thus improving pressure relief capacity.

[0169] Optionally, such as FIG. 21 As shown, the vent 6 also includes a second vent 62 and a third vent 63. The second vent 62 is located on the annular air duct plate 413 and is located at the upper end and / or the lower end of the first vent 61. The third vent 63 is located on the first air duct plate 411. The second vent 62 and the third vent 63 are spaced apart and connected. The airflow in the annular air duct 4131 flows out through the second vent 62 and the third vent 63 in sequence.

[0170] In this embodiment, the first vent 61 penetrates both the annular duct plate 413 and the first duct plate 411. This means that the annular duct plate 413 and the first duct plate 411 are in contact, thus ensuring a portion of the pressure relief capacity of the annular duct 4131. Since the cross-section of the annular duct 4131 is circular, second vents 62 are provided at both the upper and lower ends of the first vent 61, and a third vent 63 is provided on the first duct plate 411. This further increases the area of ​​the vents 6, allowing the airflow within the first duct 41 to not only exit through the first vent 61 but also through the second vent 62 and the third vent 63, thereby improving the pressure relief capacity.

[0171] Furthermore, since the second vent 62 and the third vent 63 are spaced apart, the heat exchange air in the first air duct 41 first flows out of the first air duct 41 through the second vent 62, flows into the gap between the annular air duct plate 413 and the first air duct plate 411, and then flows into the exhaust channel 64 through the third vent 63. In this way, the airflow can expand and then contract, which can further reduce noise.

[0172] Optionally, when the vent 6 includes a first vent 61, a second vent 62 and a third vent 63, the ventilation area of ​​the vent 6 is the minimum flow area of ​​the vent 6 in the same cross section in the airflow direction, that is, the minimum flow area of ​​the vent 6.

[0173] Optionally, when the vent 6 includes a first vent 61, a second vent 62, and a third vent 63, the height of the vent 6 is the minimum height of the three vents 6 in the same cross section, that is, the minimum height of the vent 6. Similarly, the width of the vent 6 is the minimum width of the three vents 6 in the same cross section, that is, the minimum width of the vent 6.

[0174] Optionally, such as FIG. 21 As shown, the vent 6 includes multiple exhaust grilles, which are arranged sequentially along the airflow direction within the duct.

[0175] In this embodiment, the vent 6 is in the form of an exhaust grille. This allows the heat exchange air to undergo a small-amplitude diffusion as it flows through each grille, resulting in a gradual decrease in airflow velocity and a smoother overall pressure drop, effectively reducing noise. Furthermore, the exhaust grille can form a slit resonant cavity with the exhaust channel 64, further enhancing the noise reduction effect.

[0176] It is understandable that the vent 6 can be in other forms, such as a microporous structure, with multiple micropores arranged in multiple rows and columns, which can also play a role in relieving pressure.

[0177] Optionally, the height of the vent 6 is the same as or similar to the height of the first air duct 41, further ensuring the pressure relief area of ​​the first air duct 41 in the height direction.

[0178] Optionally, such as FIG. 4-2 , FIG. 4-3 , FIG. 5-2 , FIG. 6-2 , FIG. 7-2 as well as FIG. 7-3 As shown, the indoor unit of the air conditioner also includes a baffle 65, which is movably disposed at the vent 6 and is used to adjust the ventilation area of ​​the vent 6.

[0179] In this embodiment, the baffle 65 makes the ventilation area of ​​the vent 6 adjustable, thus allowing the airflow from the first air duct 41 through the vent 6 to be adjusted, thereby improving the flexibility of the vent 6's pressure relief capacity and further enhancing the user experience. Furthermore, the airflow within the first air duct 41 can also be discharged through the vent 6 and the first side air outlet 102, achieving side airflow. By providing the movable baffle 65, a balance is achieved between pressure relief and noise reduction, energy saving, airflow volume, and airflow direction in the indoor air conditioning unit, further improving the user experience.

[0180] Optionally, the area of ​​the baffle 65 is greater than or equal to the area of ​​the vent 6, so that air leakage can be avoided when the baffle 65 closes the vent 6.

[0181] Optionally, the baffle 65 is slidably disposed at the vent 6, or the baffle 65 is rotatably disposed at the vent 6.

[0182] In this embodiment, the baffle 65 can move in various ways. When a sliding connection is used, the baffle 65 moves stably, has a good wind-blocking effect, and will not affect the airflow within the first air duct 41 when opened. The baffle 65 can also be rotatably mounted on the vent 6 for easy installation, and can also guide the air outlet angle of the vent 6, further improving the air outlet diversity of the indoor unit of the air conditioner.

[0183] Optionally, when the baffle 65 is rotatably positioned at the vent 6, one end of the baffle 65 is rotatably connected to one end of the vent 6, so that the baffle 65 can cover the vent 6 or open the vent 6.

[0184] Optionally, the baffle 65 is connected to a drive mechanism, which drives the baffle 65 to move in order to open or close the vent.

[0185] Optionally, such as FIG. 29 As shown. The housing 11 also has a second side air outlet 103. The housing 11 is provided with a second air duct 42 that communicates with the second side air outlet 103. The second side air outlet 103 is located below the first side air outlet 102. The second air duct 42 is located below the first air duct 41. Furthermore, an air duct partition 104 is provided between the first air duct 41 and the second air duct 42.

[0186] The second side air outlet 103 is disposed adjacent to the first side air outlet 102, and is disposed below the first side air outlet 102, such as FIG. 2 As shown, the duct partition 104 separates the first duct 41 and the second duct 42. Optionally, the indoor unit of the air conditioner is equipped with a cross-flow fan that simultaneously supplies air to both the first duct 41 and the second duct 42.

[0187] Optionally, there are two first side air outlets 102, which are respectively located on both sides of the front air outlet 101. Optionally, there are two second side air outlets 103, which are respectively located at the lower part of the first side air outlets 102.

[0188] Optionally, the ratio of the height H1 of the first side air outlet 102 to the height H2 of the second side air outlet 103 is in the range of 1:4 to 1:3.

[0189] In this embodiment, the height of the first side air outlet 102 is 1 / 4 to 1 / 3 of that of the second side air outlet 103. This allows the first side air outlet 102 to generate a high-level, light airflow when it discharges air, which is used to quickly disturb the heat pool in the upper part of the room and prevent cold air from blowing directly into people. The second side air outlet 103 is close to the ground, with a large air outlet area and low-speed air delivery. It utilizes the natural convection of cold air sinking and hot air rising to achieve a comfortable distribution of "warm feet and cool head" or "cool feet and warm head", significantly reducing the temperature gradient throughout the room. The duct partition 104 completely isolates the first and second ducts 42, preventing the two airflows from interfering with each other. It can be opened and closed independently to meet the differentiated needs of different seasons and different groups of people (children / adults). At the same time, the whole unit does not require an additional fan 21, making it compact and energy efficient.

[0190] For example, the ratio of the height H1 of the first side air outlet 102 to the height H2 of the second side air outlet 103 can be 1:4 or 1:3.

[0191] Optionally, the height H1 of the first side air outlet 102 ranges from 200mm to 300mm; and / or, the height H2 of the second side air outlet 103 ranges from 600mm to 700mm.

[0192] In the disclosed embodiment, the height H1 of the first side air outlet 102 is set between 200mm and 300mm, which corresponds precisely to the head-to-chest area of ​​an adult in a seated posture. The low-speed side airflow avoids direct airflow onto the face. The height H2 of the second side air outlet 103 is limited to between 600mm and 700mm. The second side air outlet 103 is closer to the ground, which can form a "carpet-like" airflow. In winter, hot air blows downwards, and in summer, cool air blows upwards, utilizing natural convection to quickly and evenly distribute the room temperature. The height difference between the two outlets creates dual-zone airflow, meeting different comfort needs in the same space.

[0193] For example, the height H1 of the first side air outlet 102 is 200mm, 210mm, 220mm, 250mm, 260mm, 280mm, 300mm, etc.

[0194] For example, the height H2 of the second side air outlet 103 is 600mm, 620mm, 640mm, 660mm, 680mm, 700mm, etc.

[0195] Optionally, the ratio of the inlet area of ​​the first air duct 41 to the inlet area of ​​the second air duct 42 is between 1:5 and 1:3.

[0196] In this embodiment, the area ratio ensures that the first air duct 41 accounts for only about 15% to 25% of the total air intake, while the second air duct 42 accounts for 75% to 85% of the total air intake. This large proportion of airflow is delivered close to the ground, making full use of the natural convection of cold air sinking and hot air rising, resulting in a faster and more uniform increase in room temperature and reduced energy consumption. The smaller volume of airflow exits at a high position and to the side through the first air duct 41, which can quickly disturb the heat pool in the upper part of the room during cooling without blowing directly on people, and can form an "air curtain" at a high position during heating to reduce heat loss, thus balancing comfort and energy saving.

[0197] For example, the ratio of the inlet area of ​​the first air duct 41 to the inlet area of ​​the second air duct 42 can be 1:5, 1:4 or 1:3.

[0198] Optionally, the ratio of the inlet area of ​​the exhaust passage 64 to the inlet area of ​​the first air duct 41 is in the range of 1:3 to 3:1.

[0199] In this embodiment of the disclosure, the inlet area of ​​the exhaust channel 64 can be understood as the ventilation area of ​​the vent 6. When the ratio of the ventilation area of ​​the vent 6 to the inlet area of ​​the first air duct 41 is within the above range, when the outlet area of ​​the current air outlet 101 is less than the preset area, the vent 6 can quickly release pressure, reduce the back pressure of the fan 21, and avoid surge.

[0200] For example, the ratio of the inlet area of ​​the exhaust channel 64 to the inlet area of ​​the first air duct 41 can be 1:3, 1:2, 1:1, 2:1 or 3:1.

[0201] Optionally, the ratio of the inlet area of ​​the exhaust passage 64 to the inlet area of ​​the second air duct 42 ranges from 1:8 to 1:5.

[0202] In this embodiment, when the ratio of the inlet area of ​​the vent 6 to the inlet area of ​​the second air duct 42 is within the aforementioned range, the airflow from the second air outlet 103 can be guaranteed when air is discharged from the first air outlet 102, without affecting the large airflow at the bottom. It can also create turbulence from above during cooling, preventing localized overheating and achieving uniform temperature in the vertical direction.

[0203] For example, the ratio of the inlet area of ​​the exhaust channel 64 to the inlet area of ​​the second air duct 42 is 1:8, 1:7, 1:6, 1:5, etc.

[0204] By limiting the ventilation area of ​​the vent 6 to the inlet area of ​​the first air duct 41 and the inlet area of ​​the second air duct 42 within the aforementioned range, the vent 6 can serve as both a high-pressure relief channel and a small high-level air supply hole. Under different operating conditions, it complements the upper and lower double air ducts, improving the overall comfort, reliability and energy efficiency of the machine. The structure is simple and reliable.

[0205] Optionally, the vent 6 is located near the front air outlet 101, and when the air guide body 3 is retracted, the vent 6 is located on the side of the air guide body 3.

[0206] In this embodiment, when the air guide 3 is retracted, the vent 6 is located on the side of the air guide 3. This can be understood as the distance between the vent 6 and the front plate being less than the distance between the innermost part of the air guide 3 and the front plate. Thus, when the air guide 3 is in the retracted position, the airflow effect of the first air duct 41 through the vent 6 is improved, as shown in Figure 4. Furthermore, when the air guide 3 is retracted, the resistance between the side of the air guide 3 and the side wall of the first air duct 41 is at its maximum. The vent 6, corresponding to the side of the air guide 3, can quickly release pressure and prevent the fan 21 from surging.

[0207] Optionally, when the first air duct 41 includes an annular air duct 4131, the air guide 3 is telescopically located within the annular air duct 4131, and the cross-section of the air guide 3 is also approximately circular. In this way, when the air guide 3 extends, the front air outlet 101 can form an annular air outlet, which can avoid direct blowing to the user and achieve air delivery without dead angles.

[0208] Optionally, such as FIG. 10 and FIG. 27As shown, the indoor unit of the air conditioner also includes a guide plate 43, which is located in the first air duct 41 and extends along the flow direction of the airflow in the first air duct 41; there are multiple guide plates 43, which are spaced apart along the width direction of the first air duct 41.

[0209] In this embodiment of the disclosure, after the heat exchange air flows through the spaced guide plates 43, the airflow is evenly divided into several parallel small streams, and the vortex and width-direction pulsation are weakened and rectified. This makes the velocity distribution of the heat exchange airflow more consistent when it enters the front air outlet 101 or the exhaust port, and the air delivery angle more stable. This reduces local turbulence noise and avoids the stratification of hot and cold air, making the airflow at the air outlet softer and the indoor temperature field more uniform.

[0210] Optionally, the housing 1 includes an outer shell and an air duct component 4. The outer shell includes a front panel and side panels. The front panel has a front air outlet 101, and the front panel and side panels enclose a side air outlet. The air duct component 4 is located inside the outer shell, defining a first air duct 41 and an exhaust channel 64. The air duct component 4 and the front panel enclose a second air duct 42. In this embodiment, the outer shell and the air duct component 4 together form the air ducts and air outlets of the indoor unit of the air conditioner, which facilitates processing and also facilitates the inspection and replacement of the internal air ducts and components. At the same time, the air duct component 4 and the front panel and side panels can be made of different materials to ensure the airflow function of the air duct component 4 and the appearance function of the front panel and side panels, respectively.

[0211] Optionally, the front side plate of the mounting frame 54 is provided with an air outlet, which is nested or fitted with the front air outlet 101. The front end of the annular air duct plate 413 is located inside the air outlet, so that the airflow flowing out of the annular air duct 4131 can flow out of the front air outlet 101 through the air outlet.

[0212] Optionally, the air duct component 4 includes two first air duct plates 411 arranged opposite each other along the width direction of the indoor unit of the air conditioner. The two first air duct plates 411 enclose the air duct. The air duct partition 104 is located inside the air duct and divides the air duct into a first air duct 41 and a second air duct 42. The height of the second air duct 42 is greater than or equal to the height of the first air duct 41.

[0213] Optionally, the air duct component 4 also includes an annular air duct plate 413, which is connected between the upper parts of the two first air duct plates 411, and the bottom wall of the annular air duct plate 413 is in contact with the air duct partition 104. This can maximize the flow area of ​​the annular air duct 4131, thereby increasing the air outlet area of ​​the front air outlet 101.

[0214] Optionally, the air duct component 4 further includes a second air duct plate 412, which is connected to the end of the first air duct plate 411 that is away from the first air duct 41. The second air duct plate 412 and the first air duct plate 411 enclose an exhaust channel 64. The number of second air duct plates 412 and first air duct plates 411 are the same and they correspond one-to-one.

[0215] Optionally, the vent 6 is located on the first air duct plate 411.

[0216] Optionally, when the baffle 65 is rotatably positioned at the vent 6, when the baffle 65 opens the vent 6, the baffle 65 is in contact with the second air duct plate 412, and when the baffle 65 closes the vent 6, the baffle 65 is in contact with the first air duct plate 411.

[0217] Optionally, the air duct component 4 also includes a base plate, which is connected between the first air duct plate 411 and the second air duct plate 412 and forms the base plate of the exhaust channel 64 to prevent air leakage in the exhaust channel 64.

[0218] Optionally, the air duct component 4 is a one-piece molded structure.

[0219] Optionally, the annular air duct plate 413 protrudes forward from the front end of the first air duct plate 411 so that the outlet end of the annular air duct 4131 can match the front air outlet 101 to avoid air leakage.

[0220] Optionally, the housing includes a mounting frame 54 and a front panel 111. The front panel 111 has a front air outlet 101 and is located on the front side of the mounting frame 54. The front panel 111 can serve as decoration and to create an installation space.

[0221] Optionally, the front side plate of the mounting frame 54 is provided with an air outlet, which is nested or fitted with the front air outlet 101. The front end of the annular air duct plate 413 is located inside the air outlet, so that the airflow flowing out of the annular air duct 4131 can flow out of the front air outlet 101 through the air outlet.

[0222] Optionally, such as FIG. 29 As shown, the front panel includes a front side panel and a front panel 111 of the mounting frame 54. The side panel is the side panel of the mounting frame 54. The mounting frame 54 and the air duct component 4 enclose each other to form a second air duct 42. The mounting frame 54 is provided with a guide surface on the side facing the second air duct 42.

[0223] Optionally, the housing also includes a rear cover with an air inlet. The rear cover and the front panel enclose a cavity, and the mounting frame and air duct components are located inside the cavity.

[0224] Optionally, side air outlets are provided on both sides of the front air outlet 101, and a guide surface is provided on the wall of the front panel facing the second air duct 42. The guide surface is used to guide the airflow in the second air duct 42 to the second side air outlets 103 on both sides respectively.

[0225] In this embodiment, side air outlets are symmetrically arranged on both sides of the front panel, and a guide surface is formed on the wall facing the second air duct 42. This allows the concentrated airflow from the second air duct 42 to be divided into two streams at once, which are then sent out along the left and right side air outlets respectively. The guide surface plays a dual role of "diversion + rectification," which not only prevents the airflow from forming vortices near the front air outlet 101, but also ensures that the airflow volume on the left and right sides is consistent and the direction is symmetrical, achieving "enveloping" low-speed uniform air delivery in the room, resulting in a more comfortable experience.

[0226] Optionally, such as FIG. 27 and FIG. 28 As shown, the air duct component 4 includes a first air duct plate 411 and a second air duct plate 412. The two first air duct plates 411 enclose a first air duct 41. The second air duct plate 412 is connected to the side of the first air duct plate 411 away from the first air duct 41. The second air duct plate 412 and the first air duct plate 411 enclose an exhaust channel 64. Along the flow direction of the airflow in the exhaust channel 64, the distance between the first air duct plate 411 and the second air duct plate 412 gradually increases.

[0227] In this embodiment, the distance between the first duct plate 411 and the second duct plate 412 gradually increases along the flow direction of the airflow within the exhaust channel 64. That is, the flow area of ​​the exhaust channel 64 gradually increases along the flow direction of the exhaust channel 64. This causes the airflow to decelerate and diffuse within the expansion section after leaving the exhaust port, converting kinetic energy into static pressure, reducing the outlet air velocity, and significantly weakening the exhaust noise. The gradually expanding channel reduces local eddies, minimizing the impact and vibration of the airflow on the wall of the exhaust channel 64, thus reducing noise.

[0228] Optionally, such as FIG. 6-2 As shown, with the air guide 3 fully extended, the baffle 65 is configured to close the vent 6; as FIG. 5-2 As shown, when the air guide 3 is retracted, the baffle 65 is configured to open the vent 6.

[0229] In this embodiment, when the air guide 3 is fully extended and the front air outlet 101 is in the normal annular narrow slit air supply position, the baffle 65 simultaneously closes the vent 6, allowing all airflow to flow out through the front air outlet 101, preventing air leakage and ensuring that cooling / heating efficiency and airflow distribution are not affected. When the air guide 3 is retracted and the front air outlet 101 is closed, the baffle 65 immediately opens the vent 6, allowing the high-pressure airflow in the first air duct 41 to be released instantly through the exhaust port, preventing the fan 21 from becoming pressurized, experiencing a surge in noise, or overloading the motor. Furthermore, the airflow from the vent 6 can flow out along the exhaust channel 64 and the first side air outlet 102, allowing the indoor unit of the air conditioner to also exhaust air from the side, achieving multi-dimensional airflow and improving the user experience.

[0230] Optionally, such as FIG. 7-2 As shown, when the air guide 3 is fully extended, the baffle 65 is configured to close the vent 6. When the air pressure in the first air duct 41 is greater than or equal to the pressure threshold, the baffle 65 is configured to increase the ventilation area of ​​the vent 6.

[0231] In this embodiment, after the air guide 3 is fully extended and the baffle 65 has closed the vent 6, if the internal air pressure in the first air duct 41 continues to rise and reaches the pressure threshold due to filter blockage, obstructed airflow, or other reasons, it will affect the air volume delivered to the front air outlet 101 and may cause the fan 21 to surge, increasing noise. At this time, the baffle 65 will reopen or the area of ​​the vent 6 will be enlarged. This achieves secondary pressure relief, effectively preventing the fan 21 from overloading, noise surge, or system protection shutdown, while avoiding long-term high pressure damage to internal components, further improving the safety and service life of the entire machine.

[0232] Optionally, as the cross-sectional area of ​​the first air guide wall 31 gradually increases along the air outlet direction of the front air outlet 101, the baffle 65 is configured to reduce the area of ​​the air vent 6 as the length of the air guide body 3 extends increases.

[0233] In this embodiment, as the air guide 3 extends, the distance between the circumference of the first air guide wall 31 and the inner wall of the front air outlet 101 gradually increases. Therefore, the air outlet area of ​​the front air outlet 101 gradually increases, and the static pressure within the first air duct 41 gradually decreases. At this time, the baffle 65 is simultaneously and gradually reduces the area of ​​the vent 6, causing a synchronous reduction in the pressure relief flow. This ensures that the air duct pressure remains stable throughout the movement of the air guide 3, avoiding excessive pressure relief or air leakage that could lead to energy waste, while also ensuring that the front annular slit always receives sufficient wind speed and range, achieving a dynamic balance between comfort, energy saving, and safety.

[0234] Optionally, when the target user is within the airflow range of the first side air outlet 102, the baffle 65 is configured to close the first side air outlet 102. This prevents cold / hot air from blowing directly on people, significantly improving physical comfort, while also ensuring the uniformity of the overall indoor temperature field.

[0235] Optionally, such as FIG. 4-2 As shown, the indoor unit of the air conditioner also includes an air guide plate 105, which is movably disposed at the first side air outlet 102 and the second side air outlet 103, and is used to simultaneously control the opening and closing of the first side air outlet 102 and the second side air outlet 103; wherein, when the target gas concentration in the room is greater than or equal to the concentration threshold, the air guide plate 105 is configured to open the first side air outlet 102 and the second side air outlet 103, and the baffle 65 is configured to close the vent 6.

[0236] In this embodiment, the first side air outlet 102 and the second side air outlet 103 share a single air guide plate 105. When the air guide plate 105 is open, both the first and second side air outlets 102 and 103 can simultaneously discharge air; when the air guide plate 105 is closed, both the first and second side air outlets 102 and 103 can simultaneously close. Additionally, the air guide plate 105 can also simultaneously guide the airflow from both the first and second side air outlets 102 and 103. When the indoor air quality decreases, the airflow on both sides forms a rapid "top-and-bottom" convection in the vertical direction, significantly shortening the ventilation path and expelling polluted air outdoors in the shortest possible time. With the front air outlet closed, all airflow is concentrated and ejected at high speed from the first and second side air outlets 102 and 103, enhancing overall indoor turbulence, preventing airflow short-circuiting, and improving ventilation efficiency.

[0237] Optionally, when the air guide plate 105 is open and there is a target user within the air outlet range of the first side air outlet 102, the baffle 65 is configured to close the vent 6. This can prevent the airflow from the first side air outlet 102 from blowing directly on the user's head and ensure the user's comfort.

[0238] Combination FIG. 30 As shown, in this embodiment of the air conditioner indoor unit, when the air guide 3 is retracted, all the heat exchange air from the first air duct 41 of the air conditioner indoor unit flows out from the first side air outlets 102 on both sides, as... FIG. 30 As shown in Figure d. When the air guide 3 is fully extended, all the heat exchange air in the first air duct 41 flows out from the gap between the front air outlet 101 and the air guide 3, as shown in Figure d. FIG. 30 As shown in Figure c. When the air guide body 3 extends, the heat exchange air of the first air duct 41 flows out from the gap between the front air outlet 101 and the air guide body 3, as shown in Figure c. FIG. 30As shown in Figures a and b, as the extension length of the air guide 3 increases, the air delivery angle of the front air outlet 101 gradually decreases, forming a roughly horizontal forward air delivery direction. In this way, by adjusting the extension length of the air guide 3, various air delivery modes such as concentrated air delivery and wide-angle air delivery can be achieved, and the air delivery angle can be adjusted according to the user's position to avoid direct airflow onto the user.

[0239] This disclosure also provides an air conditioner.

[0240] Optionally, the air conditioner includes an indoor unit as described above.

[0241] Optionally, the air conditioner is a cabinet-type air conditioner.

[0242] The air conditioner provided in this disclosure includes the indoor unit of any of the above embodiments, and therefore has the beneficial effects of the indoor unit of any of the above embodiments, which will not be repeated here.

[0243] Based on the above-mentioned air conditioner indoor unit, combined with FIG. 31 As shown in the figure, this disclosure provides a control method for an indoor unit of an air conditioner, including:

[0244] S101, the control device acquires indoor user information.

[0245] S102, the control device controls the extension position of the air guide body according to the indoor user information.

[0246] The control method for an indoor air conditioning unit provided in this disclosure can first obtain indoor user information to determine the user's actual air supply needs, and then control the air guide to move to a suitable extension position, thereby achieving adaptive adjustment of parameters such as air volume, air direction, air speed, and air supply distance at the front air outlet. This improves the diversity of front air outlet modes of the indoor air conditioning unit, helps to better meet the user's actual air supply needs, and thus enhances the user's air conditioning experience.

[0247] Optionally, the indoor user information may include some or all of the following: the user's need for protection against direct airflow, the user's current location, and the real-time distance between the user and the housing.

[0248] Optionally, the user's need for protection against direct airflow may include whether the user has a need for protection against direct airflow or whether the user does not have a need for protection against direct airflow.

[0249] In some embodiments, the control device can determine a user's need for protection against direct airflow based on user feedback instructions. Specifically, if the user feedback instructions include an anti-direct airflow instruction, the control device determines that the user has a need for protection against direct airflow; if the user feedback instructions do not include an anti-direct airflow instruction, the control device determines that the user does not have a need for protection against direct airflow. Thus, this embodiment of the present disclosure can receive the current user's anti-direct airflow instruction, thereby meeting the user's actual air supply needs and improving the user's air conditioning experience.

[0250] In other embodiments, the control device can determine a user's need for protection against direct airflow based on user identification information. Specifically, if the user identification information indicates that the user is an elderly person or a child, the control device determines that the user has a need for protection against direct airflow; if the user identification information indicates that the user is an adult, the control device determines that the user does not have a need for protection against direct airflow. In this way, the embodiments of this disclosure can determine the protection against direct airflow needs of different types of users, thereby meeting the actual air supply needs of various users and improving the user's air conditioning experience.

[0251] Optionally, the user's current location includes the user being within the air outlet range of the front air outlet or not being within the air outlet range of the front air outlet, and / or the user being within the air outlet range of the first side air outlet or not being within the air outlet range of the first side air outlet.

[0252] In some embodiments, the control device can control the imaging device to determine the user's current position. Specifically, if the imaging device detects that the user's image is in front of the housing, the control device determines that the user is located within the air outlet range of the front air vent, and / or, the user is not located within the air outlet range of the first side air vent; if the imaging device detects that the user's image is located on either side of the housing, the control device determines that the user is located within the air outlet range of the first side air vent, and / or, the user is not located within the air outlet range of the front air vent. In this way, an imaging device can be installed on the housing of the indoor air conditioner to capture real-time images of the user indoors, and based on this, determine the relative position between the user and the housing of the indoor air conditioner. This allows for the determination of whether the user is currently within the air outlet range of the front air vent or the air outlet range of the first side air vent, which helps to rationally adjust the air outlet parameters to better meet the user's actual air supply needs, thereby improving the user's air conditioning experience.

[0253] Optionally, the control device can control the infrared ranging device to determine the real-time distance between the user and the casing. In this way, an infrared ranging device can be installed on the casing of the indoor unit of the air conditioner to detect the real-time distance between the user and the casing, thereby determining whether the user is within a preset distance range. This allows for the reasonable adjustment of airflow parameters to better meet the user's actual air supply needs, thus improving the user's air conditioning experience.

[0254] Optionally, the control device controls the extension position of the air guide body according to the indoor user information, including: when the user has a need to prevent direct airflow and the user is within the air outlet range of the front air outlet, the control device controls the air guide body to move to a first extension position; or, when the user does not have a need to prevent direct airflow and the user is within the air outlet range of the front air outlet, the control device controls the air guide body to move to a second extension position; or, when the user has a need to prevent direct airflow and the user is not within the air outlet range of the front air outlet, the control device controls the air guide body to move to a third extension position; or, when the user does not have a need to prevent direct airflow and the user is not within the air outlet range of the front air outlet, the control device controls the air guide body to move to a fourth extension position.

[0255] Specifically, the first gap between the air guide body and the front air outlet when it is in the first extended position is smaller than the second gap between the air guide body and the front air outlet when it is in the second extended position. The third gap between the air guide body and the front air outlet when it is in the third extended position is larger than the fourth gap between the air guide body and the front air outlet when it is in the fourth extended position.

[0256] Thus, when a user requires protection from direct airflow and is located within the air outlet's airflow range, it indicates that the front-discharge mode of the air conditioner indoor unit affects user comfort and is not conducive to meeting the user's actual air supply needs. Therefore, in this embodiment, the air guide body can be controlled to move to a first extended position close to or in the retracted position. At this time, the air guide body is fully retracted or partially extended, and the first gap between it and the front air outlet is relatively small. The air guide body forms a relatively large obstruction effect on the front air outlet, resulting in a relatively small air volume and a relatively large air velocity at the front air outlet, which can mitigate the adverse effects of the front-discharge mode on user comfort. Furthermore, because the inner wall of the air guide body exerts a certain compression and guiding effect on the heat exchange air in the first air duct, the air in the first air duct forms a sloping airflow direction, i.e., it is dispersed through the front air outlet. At this time, the airflow angle formed by the front air outlet is relatively large, and the airflow distance is relatively short, which can also mitigate the adverse effects of the front-discharge mode on user comfort. Therefore, by controlling the air guide to move to a more suitable first extension position when the user has a need to prevent direct airflow and the user is within the airflow range of the front air outlet, the embodiments of this disclosure can realize a front air outlet mode with small air volume, short distance, and diffused airflow, which is conducive to better meeting the user's needs for preventing direct airflow and actual airflow needs, thereby improving the user's air conditioning experience.

[0257] Similarly, when the user has no need for direct airflow protection and is within the air outlet's range, it indicates that the front air outlet method of the indoor unit will not affect the user's comfort and may even better meet the user's actual air supply needs. Therefore, in this embodiment, the air guide can be controlled to move to a second extension position close to or at its maximum extension position. At this time, the air guide is fully or mostly extended, and the second gap between it and the front air outlet is relatively large. The obstruction effect of the air guide on the front air outlet is relatively small, the air volume of the front air outlet is relatively large, and the air velocity is relatively low, which can enhance the positive impact of the front air outlet method on the user's comfort. Moreover, at this time, the compression and guiding effect of the inner wall of the air guide on the heat exchange air in the first air duct is relatively small, so that the air in the first air duct forms a roughly horizontal forward air supply direction, that is, it is concentrated and supplied through the front air outlet. At this time, the air supply angle formed by the front air outlet is relatively small, and the air supply distance is relatively long, which can also enhance the positive impact of the front air outlet method on the user's comfort. Therefore, by controlling the air guide to move to a more suitable second extension position when the user has no need to prevent direct airflow and the user is within the airflow range of the front air outlet, the embodiments of this disclosure can achieve a front air outlet mode with large air volume, long distance, and concentrated airflow, which is conducive to better meeting the user's direct airflow needs and actual airflow needs, thereby improving the user's air conditioning experience.

[0258] Similarly, when a user needs protection from direct airflow and is not located within the air outlet's range, it indicates that the front air outlet method of the indoor unit will not affect the user's comfort and may even better meet the user's actual air supply needs. Therefore, in this embodiment, the air guide can be controlled to move to a third extension position close to or at its maximum extension position. At this time, the air guide is fully or mostly extended, and the third gap between it and the front air outlet is relatively large. The obstruction effect of the air guide on the front air outlet is relatively small, the air volume delivered by the front air outlet is relatively large, and the air volume delivered by the corresponding first side air outlet is relatively small, which can reduce the adverse effects of other air outlet methods on the user's comfort. Moreover, at this time, the compression and guiding effect of the inner wall of the air guide on the heat exchange air in the first air duct is relatively small, so that the air in the first air duct forms a roughly horizontal forward air supply direction, that is, it is concentrated and delivered through the front air outlet. At this time, the air supply angle formed by the front air outlet is relatively small, and the air supply distance is relatively long, which can enhance the beneficial effects of the front air outlet method on the user's comfort. Therefore, by controlling the air guide to move to a more suitable third extension position when the user has a need to prevent direct airflow and the user is not located within the airflow range of the front air outlet, the embodiments of this disclosure can achieve a front air outlet mode with large air volume, long distance, and concentrated airflow, which is conducive to better meeting the user's needs for preventing direct airflow and actual airflow needs, thereby improving the user's air conditioning experience.

[0259] Similarly, when the user has no need for direct airflow protection and is not located within the air outlet's airflow range, it indicates that excessive use of the front air outlet mode of the indoor unit may affect user comfort and is not conducive to meeting the user's actual air supply needs. Therefore, in this embodiment, the air guide can be controlled to move to a fourth extended position close to or in the retracted position. At this time, the air guide is fully retracted or partially extended, and the fourth gap between it and the front air outlet is relatively small. The air guide forms a relatively large obstruction effect on the front air outlet, resulting in a relatively small airflow volume at the front air outlet and a relatively large airflow volume corresponding to the first side air outlet, which can enhance the beneficial impact of other air outlet modes on user comfort. Furthermore, because the inner wall of the air guide exerts a certain compression and guiding effect on the heat exchange air in the first air duct, the air in the first air duct forms a wind direction that is inclined to all sides, that is, it is dispersed through the front air outlet. At this time, the air outlet forms a relatively large airflow angle, and the achieved airflow distance is relatively short, which can reduce the adverse effects of excessive use of the front air outlet mode on user comfort. Therefore, by controlling the air guide to move to a more suitable fourth extension position when the user has no need to prevent direct airflow and is not located within the airflow range of the front air outlet, the present embodiment can achieve a front air outlet mode with small air volume, short distance, and diffused airflow, which is conducive to better meeting the user's direct airflow needs and actual airflow needs, thereby improving the user's air conditioning experience.

[0260] Based on the above-mentioned air conditioner indoor unit, combined with FIG. 2 As shown, this disclosure provides another control method for an indoor unit of an air conditioner, including:

[0261] S201, The control device acquires indoor user information.

[0262] S202, when the user has a need to prevent direct airflow and the user is within the airflow range of the front air outlet, the control device controls the air guide to move to the first extended position.

[0263] S203, the control device adjusts the extension position of the air guide body according to the real-time distance between the user and the housing.

[0264] The control method for an indoor air conditioning unit provided in this disclosure first acquires indoor user information to determine the user's actual air supply needs. When it is determined that the user has a need to avoid direct airflow and is located within the air outlet's airflow range, it indicates that the air outlet's front airflow pattern affects user comfort and is not conducive to meeting the user's actual air supply needs. This disclosure can control the air guide to move to a first extended position close to or in the retracted position to achieve a small air volume, short distance, and diffused airflow front airflow pattern, which is beneficial for better meeting the user's need to avoid direct airflow and actual air supply needs, thereby improving the user's air conditioning experience. Furthermore, by monitoring the real-time distance between the user and the casing, this disclosure continuously adjusts the extension position of the air guide to further optimize the air outlet parameters, thereby better meeting the user's actual air supply needs and further improving the user's air conditioning experience.

[0265] Optionally, the control device adjusts the extension position of the air guide body according to the real-time distance between the user and the housing, including: when the real-time distance between the user and the housing is greater than the upper limit of the preset distance range, the control device adjusts the extension position of the air guide body to increase the gap between the air guide body and the front air outlet; or, when the real-time distance between the user and the housing is less than the lower limit of the preset distance range, the control device adjusts the extension position of the air guide body to decrease the gap between the air guide body and the front air outlet.

[0266] Thus, when the real-time distance between the user and the casing exceeds the upper limit of the preset distance range, it indicates that the user is too far from the indoor unit of the air conditioner. At this time, the heat exchange air delivered through the front air outlet is difficult to reach the user, and the user needs a longer time to feel a comfortable environment. Therefore, in this embodiment, the extension position of the air guide can be appropriately adjusted so that it gradually moves away from the retracted position, thereby increasing the gap between the air guide and the front air outlet. At this time, the air volume delivered by the front air outlet gradually increases, the air delivery direction gradually converges, and the air delivery distance can be further extended. Therefore, in this embodiment, the air guide can be further extended when the user is too far from the indoor unit of the air conditioner to appropriately increase the front air volume and air delivery distance, thereby helping the user to feel a comfortable breeze in a timely manner and further improving the user's air conditioning experience.

[0267] Similarly, when the real-time distance between the user and the casing is less than the lower limit of the preset distance range, it indicates that the user is too close to the indoor unit of the air conditioner. At this time, the heat exchange air delivered through the front air outlet can easily reach the vicinity of the user, resulting in a poor experience of avoiding direct airflow. Therefore, in this embodiment, the extension position of the air guide can be appropriately adjusted so that it gradually approaches the retracted position, thereby reducing the gap between the air guide and the front air outlet. At this time, the air volume delivered by the front air outlet gradually decreases, the air delivery direction gradually diverges, and the achieved air delivery distance is relatively shorter. Thus, in this embodiment, the air guide can be further retracted when the user is too close to the indoor unit of the air conditioner to appropriately reduce the front air volume and air delivery distance, thereby helping to meet the user's need for protection against direct airflow and further improving the user's air conditioning experience.

[0268] Optionally, if the user has a need to prevent direct airflow and the user is within the air outlet range of the front air outlet, the system further includes: if the real-time distance between the user and the housing is within a preset distance range, the control device maintains the first extended position of the air guide body to maintain the gap between the air guide body and the front air outlet.

[0269] Thus, when the real-time distance between the user and the casing is within the preset distance range, it indicates that the user is at a suitable distance from the indoor unit of the air conditioner. At this time, the heat exchange air delivered through the front air outlet can reach the user's vicinity in a timely manner without affecting the user's experience of avoiding direct airflow. Therefore, in this embodiment, the first extended position of the air guide body can be appropriately maintained to maintain the gap between the air guide body and the front air outlet. At this time, the indoor unit of the air conditioner can achieve a front air outlet mode with small air volume, short distance, and diffused airflow, which is beneficial to better meet the user's needs for avoiding direct airflow and actual air supply, thereby improving the user's air conditioning experience.

[0270] Based on the above-mentioned air conditioner indoor unit, combined with FIG. 33 As shown, this disclosure provides another control method for an indoor unit of an air conditioner, including:

[0271] S301, the control device obtains the indoor ambient temperature difference.

[0272] S302, the control device determines whether the indoor ambient temperature difference is greater than the preset ambient temperature difference. If yes, the control device executes step S303; if no, the control device executes step S304.

[0273] S303, the control device controls the air guide to move to the maximum extended position.

[0274] S304, The control device acquires indoor user information.

[0275] S305, the control device controls the extension position of the air guide body based on the indoor user information.

[0276] The control method for an indoor air conditioner unit provided in this disclosure first obtains the indoor ambient temperature difference to determine whether the indoor air conditioner unit is currently in the early temperature adjustment stage or the later temperature stabilization stage. If the indoor ambient temperature difference is greater than the preset ambient temperature difference, it indicates that the indoor air conditioner unit is in the early temperature adjustment stage. This disclosure embodiment can control the air guide to move to its maximum extension position, maximizing the gap between the air guide and the front air outlet, thereby achieving a large air volume, long distance, and concentrated air delivery front air outlet mode. This is beneficial for the indoor ambient temperature to quickly reach the user-set target temperature, creating the desired indoor comfortable environment more quickly, and thus improving the user's air conditioning experience. If the indoor temperature difference is less than or equal to the preset temperature difference, it indicates that the indoor unit of the air conditioner is in the later stage of temperature stabilization. At this time, the present embodiment further obtains indoor user information to determine the user's actual air supply needs, and then controls the air guide to move to a suitable extension position, thereby realizing adaptive adjustment of parameters such as air volume, air direction, air speed, and air supply distance of the front air outlet, improving the diversity of the front air outlet mode of the indoor unit of the air conditioner, which is conducive to better meeting the user's actual air supply needs, and thus improving the user's air conditioning experience.

[0277] Optionally, the control device acquires the indoor ambient temperature difference by: when the indoor unit of the air conditioner is operating in cooling mode, calculating the difference between the indoor ambient temperature and the indoor target temperature to obtain a first indoor ambient temperature difference; or, when the indoor unit of the air conditioner is operating in heating mode, calculating the difference between the indoor target temperature and the indoor ambient temperature to obtain a second indoor ambient temperature difference.

[0278] Thus, the present embodiment can combine the operating mode of the air conditioner indoor unit to obtain the indoor ambient temperature difference, so as to obtain the first indoor ambient temperature difference in the cooling mode or the second indoor ambient temperature difference in the heating mode. This helps to accurately determine whether the air conditioner indoor unit is currently in the early temperature adjustment stage or the later temperature stabilization stage in the cooling or heating mode, and then reasonably adjust the front air outlet mode of the air conditioner indoor unit to better meet the actual air supply needs of users.

[0279] Optionally, after the control device determines whether the indoor ambient temperature difference is greater than the preset ambient temperature difference, it further includes: if the indoor ambient temperature difference is greater than the preset ambient temperature difference, controlling the air guide plate to move to the maximum opening position.

[0280] In this way, when the indoor temperature difference is greater than the preset temperature difference, it indicates that the indoor unit of the air conditioner is in the early temperature adjustment stage. The present embodiment can control the air guide plate to move to the maximum opening position, so as to maximize the air outlet area of ​​the first side air outlet and the second side air outlet, thereby realizing a side air outlet mode with large air volume and long distance, which is conducive to the indoor temperature quickly reaching the target temperature set by the user, so as to create the indoor comfortable environment required by the user more quickly, thereby improving the user's air conditioning experience.

[0281] Based on the above-mentioned air conditioner indoor unit, combined with FIG. 34 As shown, this disclosure provides another control method for an indoor unit of an air conditioner, including:

[0282] S401, the control device acquires indoor user information.

[0283] S402, the control device controls the extension position of the air guide body based on the indoor user information.

[0284] S403, the control device controls the working position of the baffle according to the extension position of the air guide body, so as to adjust the opening area of ​​the air vent.

[0285] The control method for an indoor air conditioning unit provided in this disclosure first acquires indoor user information to determine the user's actual air supply needs. Based on this, the air guide is moved to a suitable extension position, thereby adaptively adjusting parameters such as airflow volume, direction, speed, and distance at the front air outlet. This improves the diversity of front air outlet modes for the indoor air conditioning unit, better meeting the user's actual air supply needs and enhancing the user's air conditioning experience. Furthermore, this disclosure considers the fan surge problem caused by airflow accumulation in the first duct. By combining the air pressure inside the first duct at different extension positions of the air guide, the working position of the baffle is adaptively adjusted to reasonably adjust the opening area of ​​the vent. This allows some of the heat exchange air in the first duct to be appropriately discharged through the vent, achieving a pressure relief function, reducing the risk of fan surge, improving the operational reliability of the indoor air conditioning unit, and ultimately enhancing the user experience.

[0286] Optionally, the control device controls the working position of the baffle according to the extension position of the air guide body to adjust the opening area of ​​the vent, including: the control device searches for the target working position of the corresponding baffle from a preset association relationship according to the current extension position of the air guide body; the control device controls the baffle to move to the target working position to adjust the opening area of ​​the vent.

[0287] In this way, the embodiments of this disclosure can pre-establish a preset association between the extension position of the air guide and the working position of the baffle. Then, by finding the target working position of the baffle corresponding to the current extension position of the air guide in the preset association, the baffle is controlled to move quickly to a more suitable target working position, so as to reasonably adjust the opening area of ​​the vent. This allows some of the heat exchange air in the first air duct to be appropriately discharged through the vent, thereby achieving a pressure relief function, reducing the risk of fan surge, improving the operational reliability of the indoor air conditioning unit, and thus improving the user experience.

[0288] Optionally, the larger the gap between the air guide body and the front air outlet when it is in the current extended position, the smaller the opening area of ​​the air vent when the baffle is in the target working position.

[0289] As the air guide extends, the gap between it and the front air outlet gradually increases, the outlet area gradually increases, and the static pressure in the first air duct gradually decreases. Simultaneously, the baffle is linked to gradually close the opening area of ​​the vent, reducing the pressure relief flow rate. This maintains stable duct pressure throughout the air guide's movement, preventing excessive pressure relief or air leakage that could lead to energy waste, while ensuring sufficient air velocity and range at the front annular slit, achieving a dynamic balance between comfort, energy efficiency, and safety.

[0290] Optionally, the preset association relationship includes the correspondence between the extension positions of one or more air guides and the working positions of the baffle. For example, when the air guide is in the first extension position, the control device determines that the baffle is in the first working position; when the air guide is in the second extension position, the control device determines that the baffle is in the second working position; when the air guide is in the third extension position, the control device determines that the baffle is in the third working position; and when the air guide is in the fourth extension position, the control device determines that the baffle is in the fourth working position.

[0291] Specifically, when the baffle is in the first working position, the first opening area of ​​the vent is larger than the second opening area of ​​the vent when the baffle is in the second working position. When the baffle is in the third working position, the third opening area of ​​the vent is smaller than the fourth opening area of ​​the vent when the baffle is in the fourth working position.

[0292] In this way, the air duct pressure can be kept stable throughout the movement of the air guide.

[0293] Optionally, the control method for an indoor air conditioning unit further includes: the control device acquiring the real-time air pressure in the first air duct; and when the real-time air pressure in the first air duct is greater than or equal to a pressure threshold, the control device adjusting the working position of the baffle to increase the opening area of ​​the vent.

[0294] Thus, if the internal air pressure in the first air duct continues to rise and reaches the pressure threshold due to filter blockage, obstructed airflow, or other reasons, it will affect the airflow at the front outlet 1 and may cause the fan to surge, increasing noise. In this case, the baffle will reopen or the vent area will be enlarged. This achieves secondary pressure relief, effectively preventing fan overload, noise spikes, or system protection shutdown, while also avoiding long-term high pressure damage to internal components, further improving the overall safety and service life of the unit.

[0295] Based on the above-mentioned air conditioner indoor unit, combined with FIG. 35 As shown, this disclosure provides another control method for an indoor unit of an air conditioner, including:

[0296] S501, the control device acquires indoor user information.

[0297] S502, the control device controls the extension position of the air guide body based on the indoor user information.

[0298] S503, the control device controls the opening position of the air guide vane based on the indoor user information.

[0299] The control method for an indoor air conditioning unit provided in this disclosure can first acquire indoor user information to determine the user's actual air supply needs, and then control the air guide body to move to a suitable extension position, and simultaneously control the air guide plate to move to a suitable opening position. This enables adaptive adjustment of the air supply parameters of the front air outlet and the side air outlet, thereby synergistically optimizing the front and side air supply effects of the indoor air conditioning unit, improving the diversity of air supply modes of the indoor air conditioning unit, better meeting the user's actual air supply needs, and thus enhancing the user's air conditioning experience.

[0300] Optionally, the control device controls the opening position of the air guide plate according to the indoor user information, including: when the user has a need to prevent direct airflow and the user is within the airflow range of the first side air outlet and / or the second side air outlet, the control device controls the air guide plate to move to the first open position; or, when the user does not have a need to prevent direct airflow and the user is within the airflow range of the first side air outlet and / or the second side air outlet, the control device controls the air guide plate to move to the second open position; or, when the user has a need to prevent direct airflow and the user is not within the airflow range of the first side air outlet and / or the second side air outlet, the control device controls the air guide plate to move to the third open position; or, when the user does not have a need to prevent direct airflow and the user is not within the airflow range of the first side air outlet and / or the second side air outlet, the control device controls the air guide plate to move to the fourth open position.

[0301] Specifically, when the air guide plate is in the first open position, the first air outlet area of ​​the first side air outlet and / or the second side air outlet is smaller than the second air outlet area of ​​the first side air outlet and / or the second side air outlet when the air guide plate is in the second open position. When the air guide plate is in the third open position, the third air outlet area of ​​the first side air outlet and / or the second side air outlet is smaller than the fourth air outlet area of ​​the first side air outlet and / or the second side air outlet when the air guide plate is in the fourth open position.

[0302] Thus, when a user needs protection from direct airflow and is located within the airflow range of the first and / or second side air outlets, it indicates that the side-discharge method of the indoor unit affects user comfort and is not conducive to meeting the user's actual air supply needs. Therefore, in this embodiment, the air guide plate can be controlled to move to a first open position close to or at the closed position. At this time, the air guide plate is opened at a small angle, the first air outlet area corresponding to the first and / or second side air outlets is relatively small, the air volume delivered by the side air outlets is relatively small, and the air supply direction is to avoid the user, thereby mitigating the adverse effects of the side-discharge method on user comfort. Therefore, by controlling the air guide plate to move to a more suitable first open position when the user needs protection from direct airflow and is located within the airflow range of the first and / or second side air outlets, this embodiment can achieve a side-discharge method with small air volume and air supply avoiding the user, which is beneficial to better meet the user's needs for protection from direct airflow and actual air supply needs, thereby improving the user's air conditioning experience.

[0303] Similarly, when the user has no need for protection against direct airflow and is located within the airflow range of the first and / or second side air outlets, it indicates that the side airflow method of the indoor unit of the air conditioner will not affect the user's comfort, and may even better meet the user's actual air supply needs. Therefore, in this embodiment, the air guide plate can be controlled to move to a second open position close to or at its maximum open position. At this time, the air guide plate is opened at a large angle, the first air outlet area corresponding to the first and / or second side air outlets is relatively large, the airflow volume of the side air outlets is relatively large, and the airflow direction is towards the user, thereby enhancing the beneficial impact of the side airflow method on the user's comfort. Thus, by controlling the air guide plate to a more suitable second open position when the user has no need for protection against direct airflow and is located within the airflow range of the first and / or second side air outlets, this embodiment can achieve a side airflow method with large airflow and airflow towards the user, which is beneficial to better meet the user's direct airflow needs and actual air supply needs, thereby improving the user's air conditioning experience.

[0304] Similarly, when a user needs protection from direct airflow and is not located within the airflow range of the first and / or second side air outlets, it indicates that the side airflow method of the indoor unit will not affect the user's comfort and may even better meet the user's actual air supply needs. Therefore, in this embodiment, the air guide plate can be controlled to move to a third opening position close to or at its maximum opening position. At this time, the air guide plate opens at a large angle, the third air outlet area corresponding to the first and / or second side air outlets is relatively large, the airflow volume of the side air outlets is relatively large, and the airflow volume corresponding to the front air outlet is relatively small, which can reduce the adverse effects of other airflow methods on the user's comfort. Thus, by controlling the air guide plate to a more suitable third opening position when the user needs protection from direct airflow and is not located within the airflow range of the first and / or second side air outlets, this embodiment can achieve a side airflow method with large airflow that avoids the user's air supply, which is beneficial to better meet the user's needs for protection from direct airflow and actual air supply, thereby improving the user's air conditioning experience.

[0305] Similarly, when the user has no need for protection against direct airflow and is not located within the airflow range of the first and / or second side air outlets, it indicates that excessive use of the side airflow mode of the indoor unit may affect user comfort and is not conducive to meeting the user's actual air supply needs. Therefore, in this embodiment, the air guide plate can be controlled to move to a fourth open position close to or in the closed position. At this time, the air guide plate is opened at a small angle, the first air outlet area corresponding to the first and / or second side air outlets is relatively small, the airflow volume of the side air outlets is relatively small, and the airflow volume corresponding to the front air outlet is relatively large. The airflow direction is towards the user, thereby enhancing the beneficial impact of other airflow modes on user comfort. Thus, by controlling the air guide plate to a more suitable fourth open position when the user has no need for protection against direct airflow and is not located within the airflow range of the first and / or second side air outlets, this embodiment can achieve a side airflow mode with small airflow volume and airflow towards the user, which is beneficial to better meet the user's direct airflow needs and actual air supply needs, thereby improving the user's air conditioning experience.
