[0066] It should be noted that the embodiments in the present disclosure and the features in the embodiments can be combined with each other without conflict.

[0067] As Figures 1-29 shown, the present disclosure provides a cabinet type air conditioner indoor unit, which can also be referred to as an indoor unit, an air conditioner indoor unit, a floor type indoor unit, a floor type air conditioner indoor unit, or an air conditioner indoor unit.

[0068] Optionally, in combination with Figures 1-29As shown, the indoor unit of the cabinet type air conditioner comprises a shell 1, a heat exchanger 2 and a fan 21. The shell 1 is provided with an air inlet and a front air outlet 101. The shell 1 is internally provided with a first air duct 41 which is in communication with the air inlet and the front air outlet 101. The fan 21 and the heat exchanger 2 are located in the shell 1. The fan 21 drives the indoor air sucked by the air inlet to exchange heat with the heat exchanger 2 to obtain heat exchange air, and drives the heat exchange air to flow out through the first air duct 41 and the front air outlet 101 in turn.

[0069] The indoor unit provided by the embodiments of the present disclosure can obtain heat exchange air after the airflow flowing into 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 driving of the fan 21. In this way, the front side of the indoor unit can blow air, and the indoor temperature can be adjusted.

[0070] 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.

[0071] 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.

[0072] Optionally, the heat exchanger 2 and the fan 21 are arranged in sequence in the direction from back to front. In this way, the airflow flowing into the air inlet flows through the heat exchanger 2 and the fan 21 in sequence.

[0073] Optionally, the fan 21 abuts against the inlet of the first air duct 41, so that the airflow of the fan 21 can flow more into the first air duct 41.

[0074] Optionally, the heat exchanger 2 is arc-shaped, and the heat exchanger 2 semi-surrounds the fan 21. In this way, the heat exchange area of the airflow and the heat exchanger 2 can be increased, and the heat exchange efficiency can be improved.

[0075] Optionally, the shell 1 is further provided with a first side air outlet 102, and the first air duct 41 is in communication between the air inlet and the first side air outlet 102.

[0076] Optionally, as shown, Figures 1-25 the indoor unit further comprises a wind guide body 3 which is telescopically arranged at the front air outlet 101. When the wind guide body 3 is extended, the heat exchange air is sent out from the gap between the inner wall of the front air outlet 101 and the outer wall of the wind guide body 3. When the wind guide body 3 is retracted, the front air outlet 101 is closed, and the heat exchange air can be sent out from the first side air outlet 102.

[0077] The indoor unit provided in the application, the front air outlet 101 and the first side air outlet 102 are both communicated with the first air duct 41, and the front air outlet 101 is provided with a telescopic air guide body 3. When the air guide body 3 is extended, the heat exchange air in the first air duct 41 can be sent out through the gap between the inner wall of the front air outlet 101 and the outer wall of the air guide body 3, realizing the air supply mode of the front air outlet 101, as shown in Figure 6-1 When the air guide body 3 is retracted, the air guide body 3 completely or partially closes the front air outlet 101, and the heat exchange air of the first air duct 41 is sent out through the first side air outlet 102, realizing the air supply mode of the side air outlet, as shown in Figure 5-1 .

[0078] It can be seen that the indoor unit provided in the embodiments of the present application can selectively realize the front air outlet 101 air supply or the first side air outlet 102 air supply according to the needs of the user.

[0079] Optionally, the front air outlet 101 is opened at the front plate of the shell 1, and the first side air outlet 102 is opened at the side of the front air outlet 101. In this way, the air outlet directions of the front air outlet 101 air supply mode and the side air outlet air supply mode are different.

[0080] Optionally, the front air outlet 101 is arranged at a relatively upper position of the shell 1, and the arrangement height of the first side air outlet 102 is substantially the same as that of the front air outlet 101.

[0081] Optionally, the air guide body 3 comprises a first air guide wall 31, and when the air guide body 3 is retracted, the first air guide wall 31 is located inside the shell 1, wherein at least part of the first air guide wall 31 is arc-shaped.

[0082] At least part of the outer wall of the first air guide wall 31 is arc-shaped, as shown in Figure 8 and Figure 9 . The arc-shaped first air guide wall 31 improves the air guide effect in the front air outlet 101 air supply mode. Optionally, the first air guide wall 31 is a complete air guide structure, and no air outlet is opened on the first air guide wall 31, so that when the air guide body 3 is extended, 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.

[0083] Optionally, the first air guide wall 31 is in the shape of an opening, and the air guide body 3 further comprises a first air guide cover 32 arranged to close the opening of the first air guide wall 31. As shown in Figure 8 and Figure 9 .

[0084] Optionally, the first air guide wall 31 comprises an air guide front end 311 close to the front air outlet 101, and an air guide rear end 312 connected with the air guide front end 311 and away from the front air outlet 101, wherein the air guide rear end 312 comprises a first rear air guide position 3121 connected with the air guide front end 311, and a second rear air guide position 3122 away from the air guide front end 311, and 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.

[0085] Optionally, the air guide front end 311 is a part of the first air guide wall 31 close to the front air outlet 101, as shown in Figure 11 Optionally, the air guide rear end 312 is a part of the first air guide wall 31 away from the front air outlet 101, as shown in Figure 12 Optionally, in the depth direction of the first air guide wall 31, the extension depth of the air guide front end 311 is less than the extension depth of the air guide rear end 312, and optionally, the extension depth of the air guide front end 311 accounts for 1 / 5-1 / 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.

[0086] Alternatively, the angle between the outer tangent of each part of the air guide rear end 312 and the vertical direction is less than or equal to a first angle threshold, and the angle between the outer tangent of each part of the air guide front end 311 and the vertical direction is greater than the first angle threshold. Optionally, the first angle threshold is 60°-65°. Alternatively, it can also be understood that the first air guide wall 31 is divided at the first angle threshold between the outer tangent of the first air guide wall 31 and the vertical direction to obtain the air guide front end 311 and the air guide rear end 312.

[0087] Optionally, the air guide front end 311 is arc-shaped and has a relatively large curvature, and the air guide rear end 312 can also be arc-shaped and has a relatively small curvature.

[0088] 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. The first rear air guide position 3121 is directly connected with the air guide front end 311, and the second rear air guide position 3122 is the position farthest 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, as shown in Figure 12 Thus, when the air guide body 3 is in the retracted state, the air supply effect of the first air duct 41 is improved, and when the air guide body 3 is extended, the shielding effect of the air guide body 3 on the front air outlet 101 is reduced, and the air supply effect of the front air outlet 101 is improved.

[0089] Optionally, the air guide rear end 312 is in a bowl shape, including a bowl bottom wall 3123 and a bowl side wall 3124, wherein the extension depth of the bowl bottom wall 3123 is h1, the extension depth of the bowl side wall 3124 is h2, and h1 < h2.

[0090] The air guide rear end 312 is in a bowl shape, including a bowl bottom wall 3123 and a bowl side wall 3124 arranged on the side of the bowl bottom wall 3123. It can be understood that the bowl bottom wall 3123 is substantially vertical, or the bowl bottom wall 3123 forms a small angle with the vertical direction, as shown in Figure 13 The bowl side wall 3124 has a large bending degree and forms a large angle with the vertical direction, as shown in Figure 14 .

[0091] Optionally, the angle between the outer tangent of each part of the bowl bottom wall 3123 and the vertical direction is less than or equal to a second angle threshold, and the angle between the outer tangent of each part of the bowl side wall 3124 and the vertical direction is greater than the second angle threshold. Optionally, the second angle threshold is 25°-30°. Alternatively, it can also be understood that the air guide rear end 312 is divided at the angle between the outer tangent of the air guide rear end 312 and the vertical direction, to obtain the bowl bottom wall 3123 and the bowl side wall 3124. Optionally, the bowl bottom wall 3123 and the bowl side wall 3124 are integrally formed.

[0092] In the embodiments of the present disclosure, the extension depth of the bowl bottom wall 3123 is h1, the extension depth of the bowl side wall 3124 is h2, and h1 < h2. As shown in Figure 13 and Figure 14 It can be seen that the extension depth of the bowl bottom wall 3123 is small, and the overall shape is relatively gentle, so that when the air guide body 3 is in the extended state, the air in the first air duct 41 can be in contact with the bowl bottom wall 3123, thereby reducing the air blocking effect of the bowl bottom wall 3123 when the air is discharged from the front air outlet 101, as shown in Figure 6-1 And when the air guide body 3 is in the retracted state, the relatively gentle bowl bottom wall 3123 is beneficial to the air in the first air duct 41 being discharged through the first side air outlet 102. Optionally, 2h1 < h2 < 4h1. For example, h2 can be 3 times h1.

[0093] Optionally, the width of the bowl bottom wall 3123 is k1, and the width of the bowl side wall 3124 is k2, wherein h1 / k1 < h2 / k2. Optionally, k1 > k2, so that the width of the bowl bottom wall 3123 is large and the extension depth is small, and the width of the bowl side wall 3124 is small and the extension depth is large.

[0094] It can be understood that the first air guide wall 31 is divided into 1 / 2 along the up-down direction, as shown in Figure 8 , wherein t is the dividing line at 1 / 2. The width of the bowl-shaped body bottom wall 3123 is the width of the bowl-shaped body bottom wall 3123 in the divided 1 / 2, and the width of the bowl-shaped body side wall 3124 is the width of the bowl-shaped body side wall 3124 in the divided 1 / 2.

[0095] Optionally, the included angle between the first rear air guide position 3121 of the air guide rear end 312 and the horizontal plane is a1, wherein a1<40°. Optionally, the value of a1 can be 35°, 30° or 25°.

[0096] Optionally, the included angle between the second rear air guide position 3122 of the air guide rear end 312 and the horizontal plane is a2, wherein a2>30°. Optionally, the value of a2 can be 65°, 70°, 75°, 80° or 85°. As shown in Figure 15 .

[0097] Optionally, the first side air outlet 102 is arranged at 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.

[0098] As shown in Figure 2 and Figure 3 , when the air guide body 3 is retracted, 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 effect, preventing the problem of air stagnation in the first air duct 41 when the air guide body 3 is retracted.

[0099] In the embodiment of the present disclosure, the setting height of the first side air outlet 102 is substantially the same as the setting 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, so that the air supply effect of the first side air outlet 102 is improved when the air guide body 3 is retracted.

[0100] Optionally, the shell 1 is also provided with a second side air outlet 103, and the shell 1 is provided with a second air duct 42 which is in communication with the second side air outlet 103, wherein the second side air outlet 103 is arranged at the lower part of the first side air outlet 102, the second air duct 42 is arranged at the lower part of the first air duct 41, and the air duct partition plate 104 is arranged between the first air duct 41 and the second air duct 42.

[0101] The second side air outlet 103 is arranged adjacent to the first side air outlet 102 and at the lower part of the first side air outlet 102, as shown in Figure 2The air duct partition plate 104 separates the first air duct 41 and the second air duct 42. Optionally, the air conditioner indoor unit is provided with a cross-flow fan which blows air to the first air duct 41 and the second air duct 42 at the same time.

[0102] Optionally, the number of the first side air outlets 102 is two, and the two first side air outlets 102 are arranged on the two sides of the front air outlet 101 respectively. Optionally, the number of the second side air outlets 103 is two, and the two second side air outlets 103 are arranged on the lower part of the first side air outlets 102 respectively.

[0103] Optionally, the air guide body 3 includes a maximum extension position completely extending out of the front air outlet 101, a retracted position retracted into the front air outlet 101, and an intermediate extension position between the retracted position and the maximum extension position, and the air volume of the front air outlet 101 when the air guide body 3 is in the maximum extension position is greater than the air volume of the front air outlet when the air guide body 3 is in the intermediate extension position.

[0104] As shown in Figure 30 , the air guide body 3 is in the maximum extension position, and the air guide body 3 is in the retracted position. Figure 30 Fig. c is the air outlet condition of the front air outlet 101 when the air guide body 3 is in the maximum extension position; Figure 30 Fig. d is the air outlet condition of the first side air outlet 102 when the air guide body 3 is in the retracted position; Figure 30 Fig. a or Fig. b is the air outlet condition of the front air outlet 101 when the air guide body 3 is in the intermediate extension position.

[0105] As can be seen from Figure 30 , when the air guide body 3 is in the maximum extension position, the air guide body 3 forms the smallest shielding to the front air outlet 101, and at this time, the air volume of the front air outlet 101 is the largest; when the air guide body 3 is in the intermediate extension position, the air guide body 3 forms a relatively large shielding to the front air outlet 101, and correspondingly, the air volume of the front air outlet 101 is reduced. It can be seen that the air conditioner indoor unit provided by the embodiment of the present disclosure can realize the adjustment of the air volume of the front air outlet 101 by adjusting the extension position of the air guide body 3.

[0106] Optionally, when the air guide body 3 is in the maximum extension position, the air guide body 3 forms a first air supply angle with the front air outlet 101, and when the air guide body 3 is in the intermediate extension position, the air guide body 3 forms a second air supply angle with the front air outlet 101, and the first air supply angle is smaller than the second air supply angle.

[0107] When the air guide body 3 extends to the maximum position, the air guide body 3 is in the maximum extension position, at this time, the inner wall of the first air guide wall 31 of the air guide body 3 has a smaller air guide effect on the heat exchange air in the first air duct 41, and the front air outlet 101 forms a substantially forward air supply direction, as Figure 16 and Figure 30As shown in Fig. 1c, when the air guide body 3 is located at the intermediate extension position, the air guide body 3 is not fully extended, and the inner wall of the first air guide wall 31 of the air guide body 3 forms a certain extrusion air guide effect on the heat exchange air in the first air duct 41, so that the air in the first air duct 41 is sent from the front air outlet 101 after being guided by the inner wall of the first air guide wall 31, forming a sending direction inclined to both sides, as shown in Fig. 1c. Figure 17 and Figure 30 as shown in Figs. 1a and 1b.

[0108] The air conditioner indoor unit provided by the embodiment of the present disclosure can adjust the air guide angle of the front air outlet 101 by adjusting the extension position of the air guide body 3 at the front outlet, and when the air guide body 3 is located at the retracted position, the air in the first air duct 41 is sent from the first side air outlet 102. That is, the air conditioner indoor unit provided by the embodiment of the present disclosure can adjust the air direction of the front air outlet 101 by adjusting the extension position of the air guide body 3, thereby improving the diversity of the air direction of the upper air supply of the air conditioner indoor unit.

[0109] Optionally, when the air guide body 3 is located at the maximum extension position, the air supply wind speed of the front air outlet 101 is smaller, and the air supply distance formed is closer; when the air guide body 3 is located at the intermediate extension position, the air supply wind speed of the front air outlet 101 is larger, and the air supply distance formed is farther. That is, the air conditioner indoor unit provided by the embodiment of the present disclosure can adjust the air supply wind speed of the front air outlet 101 by adjusting the extension position of the air guide body 3.

[0110] It can be seen that the air conditioner indoor unit provided by the embodiment of the present disclosure can adjust the air volume, air speed and air direction by adjusting the extension position of the air guide body 3, thereby improving the diversity of the air direction of the upper air supply of the air conditioner indoor unit.

[0111] Optionally, when the air guide body 3 is located at the maximum extension position, the distance between the front end of the air guide body 3 and the shell 1 is r1, wherein 50mm≤r1≤70mm.

[0112] When the air guide body 3 is located at the maximum extension position, a certain horizontal distance r1 is formed between the front end of the air guide body 3 and the shell 1, and optionally, 50mm≤r1≤70mm, so that the air guide body 3 can be fully extended to the front air outlet 101 without forming a large distance with the front plate of the shell 1. Optionally, r1 can be 50mm, 53mm, 55mm, 58mm, 60mm, 62mm, 65mm, 67mm or 70mm. As shown in Fig. 1c. Figure 18 ​

[0113] Optionally, when the air guide body 3 is located at the maximum extension position, a vertical line of the inner wall Q1 point of the front air outlet 101 intersects with the inner wall of the air guide body 3 at a Q2 point, and the distance between Q1 and Q2 is r2, where r2≥r1.

[0114] As shown in Figure 18 The gap formed between Q1 and Q2 can be the air outlet gap when the air guide body 3 is located at the maximum extension position. In the embodiment of the present disclosure, r2≥r1, so that the width of the air outlet gap when the air guide body 3 is located at the maximum extension position is increased, and the air supply effect of the front air outlet 101 is improved. Optionally, r2 can be 60mm, 63mm, 65mm, 68mm, 70mm, 72mm, 75mm, 77mm, 80mm, 85mm, 90mm, 95mm or 100mm. Optionally, r2<1.5r1.

[0115] 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.

[0116] In the embodiment of the present 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, as shown in Figure 19 , so that the occupied volume of the air guide body 3 in the thickness direction of the air conditioner indoor unit is reduced, so that the air guide body 3 can have a good air guide effect under the premise of extending a small distance.

[0117] Optionally, 3h≤s1≤5h.

[0118] Optionally, 230mm≤s1≤280mm. s1 can be 230mm, 235mm, 240mm, 245mm, 250mm, 255mm, 260mm, 265mm, 270mm, 275mm or 280mm.

[0119] Optionally, 65mm≤h≤80mm. h can be 65mm, 68mm, 70mm, 72mm, 75mm, 77mm or 80mm.

[0120] Optionally, when the air guide body 3 is located at the retracted position, the distance between the air guide body 3 and the front air outlet 101 is r3, where 10mm≤r3≤15mm.

[0121] In the embodiment of the present disclosure, when the air guide body 3 is located at the retracted position of the front air outlet 101, the air guide body 3 and the front air outlet 101 still have a certain distance r3, as shown in Figure 19 , so that when the air guide body 3 is located at the retracted position, the front air outlet 101 can have a slight air supply effect.

[0122] Optionally, 10mm≤r3≤15mm, r3 can be 10mm, 11mm, 12mm, 13mm, 14mm or 15mm.

[0123] Optionally, as shown in the drawings, the air conditioner indoor unit further comprises a driving assembly 5. Figures 20-25

[0124] The driving assembly 5 is drivingly connected with the air guide body 3, and is used to drive the air guide body 3 to extend and retract.

[0125] The air guide body 3 extends or retracts along the front-rear direction under the driving of the driving assembly 5, and can extend out of the front air outlet 101 or retract into the inside of the front air outlet 101.

[0126] Optionally, the first air 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 driving assembly 5 comprises a first motor 51 and a first gear 52 drivingly connected with the first motor 51, wherein the first gear 52 is engaged with the first rack 532 to drive the air guide body 3 to extend and retract.

[0127] The driving assembly 5 comprises a first motor 51 and a first gear 52, and the first gear 52 rotates under the driving of the first motor 51; the first air guide wall 31 is provided with a first track plate 53, and the first track plate 53 is fixedly arranged on the first air guide wall 31; the first track plate 53 is provided with a first rack 532, and the first gear 52 is engaged with the first rack 532 to drive the air guide body 3 to move along the front-rear direction, so that the air guide body 3 extends or retracts.

[0128] Optionally, the first track plate 53 comprises a first track plate face 531 in the form of a flat plate, and the first rack 532 is arranged on the first track plate face 531.

[0129] The first track plate face 531 of the first track plate 53 is in the form of a flat plate, and the first rack 532 is arranged on the first track plate face 531 in the form of a flat plate. In this way, the effect of driving the air guide body 3 to move along the front-rear direction by the driving assembly 5 is improved.

[0130] Optionally, the first air guide wall 31 comprises an upper wall face position 313 at the upper end and a lower wall face position 314 at the lower end, and the upper wall face position 313 and the lower wall face position 314 are both provided with the driving assembly 5.

[0131] The upper wall face position 313 and the lower wall face position 314 of the first air guide wall 31 are both provided with the driving assembly 5, so that the air guide body 3 moves under the driving of the two sets of driving assemblies 5, and the movement stability and accuracy of the air guide body 3 are improved.

[0132] ​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.

[0133] 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.

[0134] 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.

[0135] 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. Figure 21 and Figure 25 As shown.

[0136] 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.

[0137] like Figure 24 and Figure 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.

[0138] 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.

[0139] 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.

[0140] like Figure 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.

[0141] Optionally, such as Figures 4-1-7-3 as well asFigures 27-28 As shown, the side wall of the first air duct 41 is provided with an air vent 6, which communicates the inside and outside of the first air duct 41.

[0142] In the embodiment of the present disclosure, the first air duct 41 is provided with an air vent 6, so that when the air outlet area of the front air outlet 101 becomes smaller, the air resistance in the first air duct 41 increases, and when the air pressure increases, the heat exchange air in the first air duct 41 can flow out from the air vent 6, so that Figure 7-1 and 7-2 As shown, it is avoided that the heat exchange air accumulates in the first air duct 41 to generate vortex, so that it is avoided that the back pressure in the first air duct 41 is too high, thereby ensuring the working efficiency of the fan 21, reducing the noise, ensuring the uniformity of the surface wind speed of the heat exchanger 2, improving the heat exchange efficiency, avoiding the surge of the fan 21, improving the reliability of the air conditioner operation, and thereby improving the user experience.

[0143] Optionally, the air outlet area of the front air outlet 101 is adjustable, and in the case that the air outlet area of the front air outlet 101 is smaller than or equal to a preset area or the air pressure in the first air duct 41 is greater than a pressure threshold, part of the heat exchange air in the first air duct 41 can flow out through the air vent 6. In this way, it is avoided that the airflow accumulates in the first air duct 41, causing the fan 21 to surge and reducing the noise, thereby improving the user experience.

[0144] Optionally, the flow area of the first air duct gradually increases along the flow direction of the airflow in the first air duct, so that the heat exchange air in the first air duct 41 can accelerate first and then expand, can buffer the instantaneous pressure pulse, reduces the risk of surge of the fan 21, and can cooperate with the air outlet of the front air outlet and the air vent.

[0145] Optionally, as shown, Figure 4-2 The first air duct 41 includes a first air duct section 401 and a second air duct section 402 which are sequentially communicated along the flow direction of the airflow, the second air duct section 402 is provided with the front air outlet 101 at one end away from the first air duct section 401, and the flow area of the first air duct section 401 is smaller than the flow area of the second air duct section 402; wherein the air vent 6 is arranged on the side wall of the second air duct section 402.

[0146] In the embodiment of the present disclosure, the air vent 6 is arranged close to the front air outlet 101, so that when the air outlet area of the front air outlet 101 becomes smaller, the airflow accumulated at the front air outlet 101 can be discharged from the air vent 6, avoiding the airflow backflow or accumulation in the first air duct 41, ensuring the smoothness and the air outlet amount, and also reducing the noise. Moreover, the flow area of the second air duct section 402 is greater than the flow area of the first air duct section 401, so that the heat exchange air in the first air duct 41 can accelerate first and then expand, can buffer the instantaneous pressure pulse, and reduces the risk of surge of the fan 21.

[0147] Optionally, as shown, Figure 4-4As shown, the distance L1 between the front end of the air vent 6 and the front air outlet 101 ranges from 15 mm to 30 mm.

[0148] In the embodiments of the present disclosure, the distance L1 between the front end of the air vent 6 and the front air outlet 101 is kept at a distance of 15 mm to 30 mm, so that, at the moment when the air outlet area of the front air outlet 101 is closed or closed, the high static pressure difference formed in the "short distance" area can make the air flow escape from the air vent 6 in the shortest path and with the lowest resistance, thereby reducing the risk of overloading of the fan 21. Meanwhile, the distance L1 between the front end of the air vent 6 and the front air outlet 101 is greater than 15 mm, which can prevent the air vent 6 from being too close to the front air outlet 101 to cause air flow short circuit, and the distance L1 between the front end of the air vent 6 and the front air outlet 101 is less than 30 mm, which can ensure that the air vent 6 is still located in the diffuser area of the second air duct section 402, and noise reduction and compact structure are taken into account.

[0149] For example, the distance L1 between the front end of the air vent 6 and the front air outlet 101 ranges from 15 mm, 16 mm, 17 mm, 18 mm, 19 mm, 20 mm, 22 mm, 25 mm or 30 mm, etc.

[0150] Optionally, as shown, the distance L2 between the rear end of the air vent 6 and the rear end of the first air duct 41 ranges from 40 mm to 60 mm. Figure 4-4

[0151] In the embodiments of the present disclosure, the distance between the rear end of the air vent 6 and the rear end of the first air duct 41 is in the interval of 40 mm to 60 mm, so that the air vent 6 is just located outside the "vortex dead zone" upstream of the end of the first air duct 41, which not only avoids the turbulence core area caused by the wake of the fan 21, but also prevents the exhaust air flow from carrying vortex noise and reduces noise. It can also maintain a sufficient upstream pressure stabilization section, so that the air vent 6 can still utilize the main flow energy when pressure relief, and the bypass air volume is stable, and the air pressure drops faster. Meanwhile, the distance L2 between the rear end of the air vent 6 and the rear end of the first air duct 41 is greater than 40 mm, which can ensure the structure assembly allowance, and the distance L2 between the rear end of the air vent 6 and the rear end of the first air duct 41 is less than 60 mm, which can avoid increasing the depth of the whole machine and maintain the compact structure of the indoor unit.

[0152] For example, the distance L2 between the rear end of the air vent 6 and the rear end of the first air duct 41 is 40 mm, 42 mm, 45 mm, 47 mm, 50 mm, 52 mm, 56 mm, 60 mm, etc.

[0153] Optionally, the length of the air vent 6 in the height direction ranges from 200 mm to 300 mm; and / or, the width of the air vent 6 in the front-rear direction ranges from 40 mm to 60 mm.

[0154] ​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.

[0155] For example, the length of the vent 6 along the height direction is 200mm, 220mm, 240mm, 250mm, 270mm, 280mm, 300mm, etc.

[0156] For example, the width of the vent 6 along the front-to-back direction is 40mm, 45mm, 50mm, 55mm or 60mm, etc.

[0157] Optionally, such as Figures 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.

[0158] In this embodiment of the present disclosure, the indoor unit can also vent air through the first side air outlet 102, which improves the air outlet direction of the indoor unit and enables multi-dimensional air supply. Furthermore, the first side air outlet 102 can cooperate with the front air outlet 101 to form various forms of air outlet, such as environmentally friendly air, thereby improving the uniformity of indoor temperature.

[0159] 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.

[0160] 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.

[0161] In the embodiments of the present disclosure, the flow area of the exhaust passage 64 is larger than the air passage area of the air passage 6, so that when the high-speed airflow of the air passage 6 flows to the exhaust passage, the speed is reduced due to the increase of the flow area, and the dynamic pressure is efficiently converted into static pressure, thereby avoiding the outlet jet noise. The ratio of the minimum flow area of the exhaust passage 64 to the maximum air passage area of the air passage 6 is less than 5:1, which can prevent the exhaust passage 64 from being excessively expanded to generate vortex. The ratio of the minimum flow area of the exhaust passage 64 to the air passage area of the air passage 6 is greater than 2:1, which can ensure sufficient pressure expansion length and reduce airflow turbulence and noise.

[0162] For example, the ratio of the minimum flow area of the exhaust passage 64 to the air passage area of the air passage 6 can be 2:1, 3:1, 4:1, 5:1, etc.

[0163] Optionally, the air passage 6 is arranged on both sides of the first air duct 41 in the width direction, so that the first air duct 41 can be depressurized from both sides of the first air duct 41, and the airflow uniformity in the first air duct 41 is improved.

[0164] Optionally, the exhaust passage 64 is arranged on both sides of the first air duct 41 in the width direction, and each exhaust passage 64 is provided with a first side air outlet 102, so that the heat exchange air in the first air duct 41 can flow to the exhaust passage 64 from the air passage 6 on both sides in the width direction, and then be discharged through the first side air outlet 102 on both sides, thereby realizing side air outlet.

[0165] Optionally, as shown in Figure 27 and Figure 28 The shell 1 comprises an air duct piece 4, the air duct piece 4 comprises two first air duct plates 411 arranged oppositely, and an annular air duct plate 413 arranged between the two first air duct plates 411, the annular air duct plate 413 defines an annular air duct 4131 inside, and the outlet end of the annular air duct 4131 corresponds to the front air outlet 101, and the first air duct 41 comprises the annular air duct 4131.

[0166] In the embodiments of the present disclosure, the air duct close to the front air outlet 101 in the first air duct 41 is annular, so that the front air outlet 101 can also realize annular air outlet, thereby further improving the air outlet form and air outlet range of the front air outlet 101.

[0167] Optionally, as shown in Figure 21 The air passage 6 comprises a first air passage 61, and the first air passage 61 penetrates the annular air duct plate 413 and the first air duct plate 411. In this way, the first air passage 61 is closer to the front air outlet 101, can efficiently depressurize the first air duct 41, avoid airflow backflow, reduce the air pressure in the first air duct 41, and reduce noise. Furthermore, the annular air duct 4131 can increase the flow area of the heat exchange air in the first air duct 41, and also can increase the depressurization area of the first air passage 61 and improve the depressurization capacity.

[0168] Optionally, as shown in Figure 21 the vent 6 further comprises a second vent 62 and a third vent 63, the second vent 62 is arranged on the annular air duct plate 413 and located at the upper end of the first vent 61 and / or the lower end of the first vent 61, the third vent 63 is arranged on the first air duct plate 411, the second vent 62 and the third vent 63 are arranged in a spaced manner and are in communication, the airflow in the annular air duct 4131 flows out through the second vent 62 and the third vent 63 in turn.

[0169] In the embodiment of the present disclosure, the first vent 61 penetrates the annular air duct plate 413 and the first air duct plate 411. It can be understood that the annular air duct plate 413 and the first air duct plate 411 are attached at a position, so that the partial pressure relief capacity of the annular air duct 4131 can be ensured. Since the cross section of the annular air duct 4131 is circular, the second vent 62 is arranged at the upper and lower ends of the first vent 61, and then the third vent 63 is arranged on the first air duct plate 411, so that the area of the vent 6 can be further increased. The airflow in the first air duct 41 can not only flow out through the first vent 61, but also flow out through the second vent 62 and the third vent 63, so that the pressure relief capacity is improved.

[0170] In addition, since the second vent 62 and the third vent 63 are arranged in a spaced manner, that is, the heat exchange air in the first air duct 41 first flows out of the first air duct 41 through the second vent 62, and then flows into the gap between the annular air duct plate 413 and the first air duct plate 411, and then flows into the exhaust passage 64 through the third vent 63. In this way, the airflow can first expand and then contract, so that the noise can be further reduced.

[0171] Optionally, when the vent 6 comprises the first vent 61, the second vent 62 and the third vent 63, the vent area of the vent 6 is the minimum flow area of the vent 6 at the same section in the airflow flow direction, that is, the minimum flow area of the vent 6.

[0172] Optionally, when the vent 6 comprises the first vent 61, the second vent 62 and the third vent 63, the height of the vent 6 is the minimum height of the three vents 6 at the same 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 at the same section, that is, the minimum width of the vent 6.

[0173] Optionally, as shown in Figure 21 the vent 6 comprises an exhaust grille, the number of the exhaust grilles is multiple, and the multiple exhaust grilles are arranged in turn along the flow direction of the airflow in the air duct.

[0174] In the embodiments of the present disclosure, the air vent 6 adopts the form of an exhaust grille, so that the heat exchange air flow passes through each grille to perform a small pressure expansion, the air flow velocity is gradually reduced, the total pressure drop is more gentle, and the noise is effectively reduced. In addition, the exhaust grille can form a slit resonant cavity with the exhaust channel 64, further improving the noise reduction effect.

[0175] It can be understood that the air vent 6 can be in other forms, such as a microporous structure, and a plurality of micropores arranged in multiple rows and columns, which can also play a role in pressure relief.

[0176] Optionally, the height of the air 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.

[0177] Optionally, as shown in Figure 4-2 , Figure 4-3 , Figure 5-2 , Figure 6-2 , Figure 7-2 and Figure 7-3 , the indoor unit further comprises a baffle 65 movably arranged in the air vent 6, used for adjusting the air area of the air vent 6.

[0178] In the embodiments of the present disclosure, the baffle 65 makes the air area of the air vent 6 adjustable, so that the air flow of the first air duct 41 flowing out of the air vent 6 is adjustable, thereby improving the flexibility of the pressure relief capacity of the air vent 6, and further improving the user experience. In addition, the air flow in the first air duct 41 can also be discharged through the air vent 6 and the first side air outlet 102 to realize side air outlet. By setting the movable baffle 65, the indoor unit can balance the pressure relief, noise reduction, energy saving, air volume and air direction, and improve the user experience.

[0179] Optionally, the area of the baffle 65 is greater than or equal to the area of the air vent 6, so that when the baffle 65 closes the air vent 6, air leakage can be avoided.

[0180] Optionally, the baffle 65 is slidingly arranged in the air vent 6, or the baffle 65 is rotatably arranged in the air vent 6.

[0181] In the embodiments of the present disclosure, the baffle 65 can be realized in multiple ways. When the baffle 65 is slidingly connected, the baffle 65 is stable in movement, the wind shielding effect is good, and the air flow in the first air duct 41 is not affected when the baffle 65 is opened. The baffle 65 can also be rotatably arranged in the air vent 6, which is convenient to install, and can also guide the air outlet angle of the air vent 6, further improving the air outlet diversity of the indoor unit.

[0182] Optionally, when the baffle 65 is rotatably arranged in the air vent 6, one end of the baffle 65 is rotatably connected with one end of the air vent 6, so that the baffle 65 can cover the air vent 6 or open the air vent 6.

[0183] Optionally, the baffle 65 is connected with a driving mechanism for driving the baffle 65 to move to open or close the air vent.

[0184] Optionally, as Figure 29 shown. The shell 11 is also provided with a second side air outlet 103, and the shell 11 is provided with a second air duct 42 in communication with the second side air outlet 103, wherein the second side air outlet 103 is arranged at the lower part of the first side air outlet 102, the second air duct 42 is arranged at the lower part of the first air duct 41, and the air duct partition 104 is arranged between the first air duct 41 and the second air duct 42.

[0185] The second side air outlet 103 is arranged adjacent to the first side air outlet 102 and at the lower part of the first side air outlet 102, as Figure 2 shown. The air duct partition 104 separates the first air duct 41 and the second air duct 42. Optionally, the air conditioner indoor unit is provided with one cross-flow fan which simultaneously supplies air to the first air duct 41 and the second air duct 42.

[0186] Optionally, the number of the first side air outlets 102 is two, and the two first side air outlets 102 are arranged at the two sides of the front air outlet 101. Optionally, the number of the second side air outlets 103 is two, and the two second side air outlets 103 are arranged at the lower parts of the first side air outlets 102.

[0187] 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.

[0188] In the embodiments of the present disclosure, the height of the first side air outlet 102 is 1 / 4 to 1 / 3 of the height of the second side air outlet 103, so that when the first side air outlet 102 blows air, a high light wind volume can be formed to quickly disturb the room upper thermal mass and avoid cold wind directly blowing on people. The second side air outlet 103 is close to the ground, and the large air outlet area blows air at low speed, which utilizes the natural convection of cold air sinking and hot air floating to realize the comfortable distribution of "feet warm head cool" or "feet cool head warm", and the temperature gradient of the whole house is significantly reduced; the air duct partition 104 completely isolates the first and second air ducts 42 to avoid mutual interference of the two air flows, and can be independently opened and closed to meet the differentiated needs of different seasons and different groups of people (children / adults), while the whole machine does not need to increase an additional fan 21, and the structure is compact and the energy efficiency is high.

[0189] 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.

[0190] 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.

[0191] 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.

[0192] For example, the height H1 of the first side air outlet 102 is 200mm, 210mm, 220mm, 250mm, 260mm, 280mm, 300mm, etc.

[0193] For example, the height H2 of the second side air outlet 103 is 600mm, 620mm, 640mm, 660mm, 680mm, 700mm, etc.

[0194] 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.

[0195] 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.

[0196] 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.

[0197] 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.

[0198] 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.

[0199] For example, the ratio of the inlet area of the exhaust passage 64 to the inlet area of the first air duct 41 can be 1:3, 1:2, 1:1, 2:1, or 3:1.

[0200] 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.

[0201] In the embodiments of the present disclosure, when the ratio of the inlet area of the vent 6 to the inlet area of the second air duct 42 is in the above range, the air volume of the second side air outlet 103 can be ensured when the air is discharged from the first side air outlet 102, and the flow of the large air volume at the lower part is not affected. The turbulence can also be formed from the top during refrigeration to prevent local overheating in the room and achieve temperature uniformity in the up-down direction.

[0202] For example, the ratio of the inlet area of the exhaust passage 64 to the inlet area of the second air duct 42 can be 1:8, 1:7, 1:6, 1:5, etc.

[0203] By limiting the vent 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 above range, the vent 6 can serve as both a high-pressure relief passage and a small amount of high-position air supplement hole, and complement the upper and lower air ducts under different working conditions, thereby improving the comfort, reliability, and energy efficiency of the whole machine, and the structure is simple and reliable.

[0204] Optionally, the vent 6 is arranged close to the front air outlet 101, and when the air guide body 3 is retracted, the vent 6 is located at the side of the air guide body 3.

[0205] In the embodiments of the present disclosure, when the air guide body 3 is retracted, the vent 6 is located at the side of the air guide body 3, which can be understood as that the distance between the vent 6 and the front plate is less than the distance between the innermost side of the air guide body 3 and the front plate. In this way, when the air guide body 3 is located at the retracted position, the air flow of the first air duct 41 through the vent 6 is improved. As shown in FIG. 4. When the air guide body 3 is retracted, the resistance between the side of the air guide body 3 and the side wall of the first air duct 41 is the largest, the vent 6 corresponds to the side of the air guide body 3, and the vent 6 can quickly relieve pressure to avoid fan 21 surge.

[0206] Optionally, when the first air duct 41 includes a ring-shaped air duct 4131, the air guide body 3 is telescopically located in the ring-shaped air duct 4131, and the cross section of the air guide body 3 is also circular, so that when the air guide body 3 is extended, the front air outlet 101 can form a ring-shaped air outlet, which can avoid directly blowing to the user and achieve air supply without dead angle.

[0207] Optionally, as Figure 10 and Figure 27As shown, the indoor unit further comprises guide plates 43, which are located in the first air duct 41 and extend along the flow direction of the airflow in the first air duct 41; wherein the number of the guide plates 43 is multiple, and the multiple guide plates 43 are arranged in the width direction of the first air duct 41.

[0208] In the embodiments of the present disclosure, after the heat exchange airflow passes through the guide plates 43 arranged at intervals, the airflow is uniformly divided into several parallel small flow bundles, and the vortex and width direction pulsation are weakened and rectified, so that the speed distribution of the heat exchange airflow entering the front air outlet 101 or the exhaust port is more consistent, the air supply angle is more stable, the local turbulent noise is reduced, the cold and hot airflow layering is avoided, and the air outlet airflow is softer and the indoor temperature field is more uniform.

[0209] Optionally, the shell 1 comprises a shell and an air duct piece 4, the shell comprises a front plate and a side plate, the front plate is provided with the front air outlet 101, and the front plate and the side plate enclose a side air outlet; the air duct piece 4 is located in the shell, the air duct piece 4 defines the first air duct 41 and the exhaust passage 64, and the air duct piece 4 and the front plate enclose the second air duct 42. In the embodiments of the present disclosure, the shell and the air duct piece 4 jointly form the air duct and the air outlets of the indoor unit, which is convenient for processing and convenient for maintenance and replacement of the internal air duct and components. At the same time, the air duct piece 4, the front plate and the side plate can be made of different materials to respectively ensure the air flow function of the air duct piece 4 and the appearance function of the front plate and the side plate.

[0210] Optionally, the front side plate provided with the mounting framework 54 is provided with an air outlet opening, the air outlet opening is nested or attached with the front air outlet 101, and the front end of the annular air duct plate 413 is located in the air outlet opening, 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 opening.

[0211] Optionally, the air duct piece 4 comprises two first air duct plates 411 oppositely arranged in the width direction of the indoor unit, the two first air duct plates 411 enclose an air duct, the air duct partition plate 104 is located in the air duct and separates the air duct into the first air duct 41 and the second air duct 42, and the height of the second air duct 42 is greater than or equal to the height of the first air duct 41.

[0212] Optionally, the air duct piece 4 further comprises an annular air duct plate 413, which is connected between the upper portions of the two first air duct plates 411, and the bottom wall of the annular air duct plate 413 is attached with the air duct partition plate 104, so as to maximize the flow area of the annular air duct 4131 and further increase the air outlet area of the front air outlet 101.

[0213] Optionally, the air duct member 4 further comprises a second air duct plate 412, the second air duct plate 412 is connected to the first air duct plate 411 away from the first air duct 41, and the second air duct plate 412 and the first air duct plate 411 enclose the exhaust passage 64. Wherein, the number of the second air duct plate 412 is the same as the first air duct plate 411 and one-to-one correspondence.

[0214] Optionally, the air vent 6 is provided on the first air duct plate 411.

[0215] Optionally, when the baffle 65 is rotated to open the air vent 6, the baffle 65 is attached to the second air duct plate 412; when the baffle 65 closes the air vent 6, the baffle 65 is attached to the first air duct plate 411.

[0216] Optionally, the air duct member 4 further comprises a bottom plate, the bottom plate is connected between the first air duct plate 411 and the second air duct plate 412, and forms the bottom plate of the exhaust passage 64, avoiding air leakage of the exhaust passage 64.

[0217] Optionally, the air duct member 4 is an integral structure.

[0218] 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 cooperates with the front air outlet 101, avoiding air leakage.

[0219] Optionally, the shell comprises a mounting skeleton 54 and a front panel 111, the front panel 111 is provided with a front air outlet 101 and located on the front side of the mounting skeleton 54, and the front panel 111 can play a role of decoration and forming a mounting space.

[0220] Optionally, the front side plate of the mounting skeleton 54 is provided with an air outlet, the air outlet is nested or attached with the front air outlet 101, and the front end of the annular air duct plate 413 is located in the air outlet, so that the airflow in the annular air duct 4131 can flow out from the front air outlet 101 through the air outlet.

[0221] Optionally, as shown in Figure 29 , the front plate comprises the front side plate of the mounting skeleton 54 and the front panel 111, the side plate is the side plate of the mounting skeleton 54, and the mounting skeleton 54 and the air duct member 4 enclose the second air duct 42. And the side of the mounting skeleton 54 towards the second air duct 42 is provided with a flow guide surface.

[0222] Optionally, the shell further comprises a rear cover, the rear cover is provided with an air inlet, the rear cover and the front panel enclose a chamber, and the mounting skeleton and the air duct member are located in the chamber.

[0223] Optionally, the front air outlet 101 is provided with side air outlets on both sides, and the front plate is provided with a flow guide surface on the wall surface facing the second air duct 42, and the flow 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.

[0224] In the embodiments of the present disclosure, the side air outlets are symmetrically arranged on both sides of the front plate, and the flow guide surface is formed on the wall surface of the front plate facing the second air duct 42, so that the concentrated airflow from the second air duct 42 can be divided into two streams at one time and sent out along the left and right side air outlets, respectively. The flow guide surface plays a dual role of “flow division + flow regulation”, which not only avoids the formation of vortex flow near the front air outlet 101, but also makes the left and right side air outlet flows have consistent flow rate and symmetrical direction, so as to realize the “encircling” uniform air supply with low air speed in the room and make the user feel more comfortable.

[0225] Optionally, as shown in Figure 27 and Figure 28 , the air duct piece 4 includes a first air duct plate 411 and a second air duct plate 412, the two first air duct plates 411 enclose the first air duct 41, and the second air duct plate 412 is connected to one side of the first air duct plate 411 away from the first air duct 41, and the second air duct plate 412 and the first air duct plate 411 enclose the exhaust passage 64. Along the flow direction of the airflow in the exhaust passage 64, the distance between the first air duct plate 411 and the second air duct plate 412 gradually increases.

[0226] In the embodiments of the present disclosure, along the flow direction of the airflow in the exhaust passage 64, the distance between the first air duct plate 411 and the second air duct plate 412 gradually increases, that is, along the flow direction of the exhaust passage 64, the flow area of the exhaust passage 64 gradually increases, so that the airflow slows down and expands in the expansion section after leaving the exhaust port, the kinetic energy is converted into static pressure, the outlet air speed is reduced, and the exhaust noise is significantly reduced. The gradually expanding passage reduces local vortex flow, reduces the impact and vibration of the airflow on the wall surface of the exhaust passage 64, and reduces noise.

[0227] Optionally, as shown in Figure 6-2 , when the air guide body 3 is fully extended, the baffle 65 is configured to close the air vent 6; as shown in Figure 5-2 , when the air guide body 3 is retracted, the baffle 65 is configured to open the air vent 6.

[0228] In the embodiments of the present disclosure, when the air guide body 3 is fully extended and the front air outlet 101 is in normal annular narrow slit air supply, the baffle 65 synchronously closes the air vent 6, and all air volume flows out of the front air outlet 101, avoiding air leakage and ensuring the refrigeration / heating efficiency and air speed distribution are not affected. When the air guide body 3 is retracted and the front air outlet 101 is closed, the baffle 65 immediately opens the air vent 6, so that the high-pressure airflow in the first air duct 41 is instantaneously discharged through the exhaust port, preventing the fan 21 from being over-pressured, the noise from surging, or the motor from being overloaded, and the airflow flowing out of the air vent 6 can flow out along the exhaust passage 64 and the first side air outlet 102, so that the indoor unit can also blow air from the side, achieving multi-dimensional air outlet and improving the user's experience.

[0229] Optionally, as shown in FIG. 6, in the case where the air guide body 3 is fully extended, the baffle 65 is configured to close the air vent 6, and in the case where the wind pressure in the first air duct 41 is greater than or equal to a pressure threshold, the baffle 65 is configured to increase the air vent area of the air vent 6. Figure 7-2

[0230] In the embodiments of the present disclosure, after the air guide body 3 is fully extended and the baffle 65 has closed the air vent 6, if the internal wind pressure of the first air duct 41 continues to rise and reaches the pressure threshold due to reasons such as filter screen blockage, air outlet obstruction, etc., the air supply of the front air outlet 101 will be affected and the fan 21 may be surging, increasing the noise. At this time, the baffle 65 reopens or enlarges the area of the air vent 6. In this way, secondary pressure relief can be achieved, effectively preventing the fan 21 from being overloaded, the noise from surging, or the system from being shut down for protection, while avoiding long-term high pressure from damaging internal components, further improving the safety and service life of the entire machine.

[0231] Optionally, in the case where the cross-sectional area of the first air guide wall 31 gradually increases in the air outlet direction of the front air outlet 101, as the length of the air guide body 3 extends, the baffle 65 is configured to reduce the area of the air vent 6.

[0232] In the embodiments of the present disclosure, as the air guide body 3 continuously extends, the distance between the circumferential direction of the first air guide wall 31 and the inner wall of the front air outlet 101 gradually increases, so the air outlet area of the front air outlet 101 gradually increases and the static pressure in the first air duct 41 gradually decreases. At this time, the baffle 65 is linked to gradually close the air vent 6, so that the pressure relief flow is synchronously reduced. In this way, the air duct pressure can be kept stable during the movement of the air guide body 3, avoiding excessive pressure relief or air leakage causing energy waste, and ensuring that the front side annular narrow slit always obtains sufficient air speed and range, achieving a dynamic balance of comfort, energy saving and safety.

[0233] ​Optionally, when the target user is located in the air outlet range of the first side air outlet 102, the baffle 65 is configured to close the first side air outlet 102. In this way, the cold / hot air can be prevented from directly blowing on the user, and the thermal comfort is significantly improved, while the overall uniformity of the indoor temperature field is taken into account.

[0234] Optionally, as shown in Figure 4-2 The indoor unit further includes a guide vane 105 movably arranged at the first side air outlet 102 and the second side air outlet 103, for simultaneously controlling 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 guide vane 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 air vent 6.

[0235] In the embodiment of the present disclosure, the first side air outlet 102 and the second side air outlet 103 share one guide vane 105, so that when the guide vane 105 is opened, the first side air outlet 102 and the second side air outlet 103 can simultaneously blow air, and when the guide vane 105 is closed, the first side air outlet 102 and the second side air outlet 103 can be closed at the same time. In addition, the guide vane 105 can also simultaneously guide the air flow of the first side air outlet 102 and the second side air outlet 103. When the gas quality in the room decreases, the air flow on both sides forms a rapid convection in the height direction, significantly shortening the ventilation path, and the dirty gas can be discharged outside in the shortest time; the front air outlet is closed, and all the air flow is concentrated and sprayed out at high speed from the first side air outlet 102 and the second side air outlet 103, which enhances the overall disturbance in the room, avoids air flow short circuit, and improves the ventilation efficiency.

[0236] Optionally, when the guide vane 105 is opened and there is a target user in the air outlet range of the first side air outlet 102, the baffle 65 is configured to close the air vent 6, so that the air flow from the first side air outlet 102 can be prevented from directly blowing on the user's head, and the comfort of the user is ensured.

[0237] In combination with Figure 30 As shown in the embodiment of the indoor unit of the present disclosure, when the guide vane 3 is retracted, all the heat exchange air of the first air duct 41 of the indoor unit flows out from the two side first side air outlets 102, as shown in the d graph of Figure 30 When the guide vane 3 is fully extended, all the heat exchange air of the first air duct 41 flows out from the gap between the front air outlet 101 and the guide vane 3, as shown in the c graph of Figure 30 When the guide vane 3 is partially extended, the heat exchange air of the first air duct 41 flows out from the gap between the front air outlet 101 and the guide vane 3, as shown in the c graph of Figure 30As shown in FIGS. a and b, and as the length of the air guide 3 extending increases, the blowing angle of the front air outlet 101 gradually decreases, forming a substantially horizontal forward blowing direction. In this way, by adjusting the length of the air guide 3 extending, various blowing forms such as convergent blowing and wide-angle blowing can be achieved, and the blowing angle can be adjusted according to the position of the user to avoid directly blowing on the user.

[0238] The present disclosure also provides an air conditioner.

[0239] Optionally, the air conditioner comprises the indoor unit as described above.

[0240] Optionally, the air conditioner is a cabinet air conditioner.

[0241] The air conditioner provided by the embodiments of the present disclosure has the beneficial effects of the indoor unit of any of the above embodiments, and thus the detailed description is omitted here.

[0242] Based on the above air conditioner indoor unit, in combination with Figure 31 The present disclosure provides a control method for an indoor unit, comprising:

[0243] S101, the control device acquires indoor user information.

[0244] S102, the control device controls the extension position of the air guide according to the indoor user information.

[0245] The control method for an indoor unit provided by the embodiments of the present disclosure can first acquire indoor user information to determine the actual blowing demand of the user, and then control the air guide to move to a suitable extension position, thereby achieving adaptive adjustment of the parameters such as the air volume, air direction, air speed, and blowing distance of the front air outlet, improving the diversity of the front air outlet mode of the indoor unit, and being conducive to better meeting the actual blowing demand of the user, thereby improving the air conditioner use experience of the user.

[0246] Optionally, the indoor user information includes part or all of the user anti-direct blowing demand, the current position of the user, and the real-time distance between the user and the shell.

[0247] Optionally, the user anti-direct blowing demand includes the user having an anti-direct blowing demand or the user not having an anti-direct blowing demand.

[0248] In some embodiments, the control device can determine the user anti-direct blowing demand according to the user feedback instruction. Specifically, in the case where the user feedback instruction includes an anti-direct blowing instruction, the control device determines that the user has an anti-direct blowing demand; in the case where the user feedback instruction does not include an anti-direct blowing instruction, the control device determines that the user does not have an anti-direct blowing demand. In this way, the present disclosure can receive the anti-direct blowing instruction of the current user, thereby meeting the actual blowing demand of the user, and being conducive to improving the air conditioner use experience of the user.

[0249] In some embodiments, the control device can determine the user's demand for direct-blow prevention according to the user identity information. Specifically, in a case where the user identity information indicates that the user is an old user or a child user, the control device determines that the user has a demand for direct-blow prevention; in a case where the user identity information indicates that the user is an adult user, the control device determines that the user has no demand for direct-blow prevention. In this way, the embodiments of the present disclosure can determine the direct-blow prevention demands of different types of users, thereby meeting the actual air supply demands of various users and improving the user's air conditioner use experience.

[0250] Optionally, the user's current position includes a position of the user in the outflow range of the front air outlet or a position of the user out of the outflow range of the front air outlet, and / or a position of the user in the outflow range of the first side air outlet or a position of the user out of the outflow range of the first side air outlet.

[0251] In some embodiments, the control device can control the photographing device to determine the user's current position. Specifically, in a case where the photographing device identifies that the user image is in front of the shell, the control device determines that the user is in the outflow range of the front air outlet and / or the user is out of the outflow range of the first side air outlet; in a case where the photographing device identifies that the user image is on both sides of the shell, the control device determines that the user is in the outflow range of the first side air outlet and / or the user is out of the outflow range of the front air outlet. In this way, the photographing device can be installed on the shell of the indoor unit to collect real-time images of the indoor user, and determine the positional relationship between the user and the shell of the indoor unit, thereby determining whether the user is in the outflow range of the front air outlet or the outflow range of the first side air outlet, which is conducive to reasonably adjusting the air outlet parameters to better meet the user's actual air supply demand and improve the user's air conditioner use experience.

[0252] Optionally, the control device can control the infrared distance measuring device to determine the real-time distance between the user and the shell. In this way, the infrared distance measuring device can be installed on the shell of the indoor unit to detect the real-time distance between the user and the shell, thereby determining whether the user is within the preset distance range, which is conducive to reasonably adjusting the air outlet parameters to better meet the user's actual air supply demand and improve the user's air conditioner use experience.

[0253] Optionally, the control device controls the extension position of the air deflector according to the indoor user information, including: in a case that the user has the anti-direct-blow requirement and the user is located in the air outlet range of the front air outlet, the control device controls the air deflector to move to the first extension position; or in a case that the user does not have the anti-direct-blow requirement and the user is located in the air outlet range of the front air outlet, the control device controls the air deflector to move to the second extension position; or in a case that the user has the anti-direct-blow requirement and the user is not located in the air outlet range of the front air outlet, the control device controls the air deflector to move to the third extension position; or in a case that the user does not have the anti-direct-blow requirement and the user is not located in the air outlet range of the front air outlet, the control device controls the air deflector to move to the fourth extension position.

[0254] The first gap between the air deflector and the front air outlet in the first extension position is smaller than the second gap between the air deflector and the front air outlet in the second extension position. The third gap between the air deflector and the front air outlet in the third extension position is larger than the fourth gap between the air deflector and the front air outlet in the fourth extension position.

[0255] In this way, when the user has the anti-direct-blow requirement and the user is located in the air outlet range of the front air outlet, it indicates that the front air outlet mode of the indoor unit affects the user's comfort feeling and is not conducive to meeting the actual air supply requirement of the user. Therefore, the air deflector can be controlled to move to the first extension position close to or at the retracted position, at which the air deflector is completely retracted or partially extended, and the first gap between the air deflector and the front air outlet is relatively small. The air deflector forms a relatively large shielding effect on the front air outlet, and the air supply amount of the front air outlet is relatively small and the air supply speed is relatively large, which can reduce the adverse effect of the front air outlet mode on the user's comfort feeling. In addition, the inner wall of the air deflector forms a certain extrusion and air deflection effect on the heat exchange air in the first air duct, so that the air in the first air duct forms a divergent air supply direction to the four directions, that is, the air is diffused and supplied through the front air outlet, at which time the air supply angle formed by the front air outlet is relatively large and the air supply distance is relatively close, which can also reduce the adverse effect of the front air outlet mode on the user's comfort feeling. Therefore, by controlling the air deflector to move to the relatively appropriate first extension position in the case that the user has the anti-direct-blow requirement and the user is located in the air outlet range of the front air outlet, the front air outlet mode of small air volume, close distance and divergence can be realized, which is conducive to better meeting the anti-direct-blow requirement and the actual air supply requirement of the user, and thus the air conditioning use experience of the user is improved.

[0256] Similarly, when the user has a direct-blowing prevention requirement and the user is not located in the air outlet range of the front air outlet, it indicates that the front air outlet mode of the indoor unit does not affect the user's comfort feeling, and even more beneficially meets the actual air supply requirement of the user. Therefore, the disclosed embodiment can control the air guide body to move to a third extended position close to or at the maximum extended position, at which the air guide body is completely or mostly extended, and the third gap between the air guide body and the front air outlet is relatively large. The air guide body has a relatively small shielding effect on the front air outlet, and the air supply volume of the front air outlet is relatively large, and the air supply speed is relatively small, which can improve the beneficial effect of the front air outlet mode on the user's comfort feeling. At this time, the inner wall of the air guide body has a relatively small extrusion and air guide effect on the heat exchange air in the first air duct, so that the air in the first air duct forms a substantially horizontal forward air supply direction, that is, the air is gathered 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 far, which can also improve the beneficial effect of the front air outlet mode on the user's comfort feeling. Therefore, by controlling the air guide body to move to a relatively appropriate third extended position when the user has a direct-blowing prevention requirement and the user is not located in the air outlet range of the front air outlet, the disclosed embodiment can realize a front air outlet mode with large air volume, long distance, and gathered air supply, which is beneficial to better meet the direct-blowing prevention requirement and the actual air supply requirement of the user, and further improves the air conditioner use experience of the user.

[0257] Similarly, when the user has a direct-blowing prevention requirement and the user is not located in the air outlet range of the front air outlet, it indicates that the front air outlet mode of the indoor unit does not affect the user's comfort feeling, and even more beneficially meets the actual air supply requirement of the user. Therefore, the disclosed embodiment can control the air guide body to move to a third extended position close to or at the maximum extended position, at which the air guide body is completely or mostly extended, and the third gap between the air guide body and the front air outlet is relatively large. The air guide body has a relatively small shielding effect on the front air outlet, and the air supply volume of the front air outlet is relatively large, and the air supply speed is relatively small, which can improve the beneficial effect of the front air outlet mode on the user's comfort feeling. At this time, the inner wall of the air guide body has a relatively small extrusion and air guide effect on the heat exchange air in the first air duct, so that the air in the first air duct forms a substantially horizontal forward air supply direction, that is, the air is gathered 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 far, which can also improve the beneficial effect of the front air outlet mode on the user's comfort feeling. Therefore, by controlling the air guide body to move to a relatively appropriate third extended position when the user has a direct-blowing prevention requirement and the user is not located in the air outlet range of the front air outlet, the disclosed embodiment can realize a front air outlet mode with large air volume, long distance, and gathered air supply, which is beneficial to better meet the direct-blowing prevention requirement and the actual air supply requirement of the user, and further improves the air conditioner use experience of the user.

[0258] Similarly, when the user has no direct-blowing requirement and the user is not located in the air outlet range of the front air outlet, it indicates that the front air outlet mode of the indoor unit is used excessively, which can affect the user's comfort feeling and is not conducive to meeting the actual air supply requirement of the user. Therefore, the fourth extended position close to or at the retracted position of the air guide body can be controlled by the control device in the embodiment of the present disclosure. At this time, the air guide body is fully retracted or partially extended, and the fourth gap between the air guide body and the front air outlet is relatively small. The air guide body forms a relatively large shielding effect on the front air outlet, and the air supply amount of the front air outlet is relatively small, and the air supply amount of the first side air outlet is relatively large, which can improve the beneficial influence of other air outlet modes on the user's comfort feeling. In addition, the inner wall of the air guide body forms a certain extrusion air guide effect on the heat exchange air in the first air duct, so that the air in the first air duct forms a tilting air supply direction to the surrounding, that is, the air is dispersed and supplied through the front air outlet. At this time, the air supply angle formed by the front air outlet is relatively large, and the air supply distance is relatively close, which can reduce the adverse effect of the excessive use of the front air outlet mode on the user's comfort feeling. Therefore, by controlling the air guide body to move to a more appropriate fourth extended position when the user has no direct-blowing requirement and the user is not located in the air outlet range of the front air outlet, the front air outlet mode of the embodiment of the present disclosure can realize small air volume, short distance and dispersion air supply, which is conducive to better meeting the direct-blowing requirement and actual air supply requirement of the user, and further improving the air conditioner use experience of the user.

[0259] Based on the above indoor unit, in combination with Figure 2 The embodiment of the present disclosure provides another control method for an indoor unit, comprising:

[0260] S201, the control device acquires indoor user information.

[0261] S202, in the case that the user has a direct-blowing requirement and the user is located in the air outlet range of the front air outlet, the control device controls the air guide body to move to the first extended position.

[0262] S203, the control device adjusts the extended position of the air guide body according to the real-time distance between the user and the shell.

[0263] The control method for the indoor unit provided by the embodiment of the present disclosure can first acquire indoor user information to determine the actual air supply demand of the user. When it is determined that the user has a direct-blow prevention demand and the user is located in the air outlet range of the front air outlet, it indicates that the front air outlet mode of the indoor unit affects the user's comfort feeling and is not conducive to meeting the actual air supply demand of the user. The embodiment of the present disclosure can control the air deflector to move to the first extended position close to or at the retracted position to achieve the front air outlet mode of small air volume, close distance and divergent air supply, which is conducive to better meeting the direct-blow prevention demand and the actual air supply demand of the user, thereby improving the user's air conditioner use experience. Moreover, by monitoring the real-time distance between the user and the shell, the embodiment of the present disclosure continuously adjusts the extended position of the air deflector to further optimize the air outlet parameters of the front air outlet, thereby better meeting the actual air supply demand of the user and being conducive to further improving the user's air conditioner use experience.

[0264] Optionally, the control device adjusts the extended position of the air deflector according to the real-time distance between the user and the shell, including: in the case that the real-time distance between the user and the shell is greater than the upper limit value of the preset distance range, the control device adjusts the extended position of the air deflector to increase the gap between the air deflector and the front air outlet; or in the case that the real-time distance between the user and the shell is less than the lower limit value of the preset distance range, the control device adjusts the extended position of the air deflector to reduce the gap between the air deflector and the front air outlet.

[0265] In this way, when the real-time distance between the user and the shell is greater than the upper limit value of the preset distance range, it indicates that the user is too far away from the indoor unit, and at this time, the heat exchange air sent through the front air outlet is difficult to reach the vicinity of the user, and the user needs a long time to feel a comfortable environment. Therefore, the embodiment of the present disclosure can appropriately adjust the extended position of the air deflector to gradually move away from the retracted position, thereby increasing the gap between the air deflector and the front air outlet. At this time, the air supply volume of the front air outlet gradually increases, the air supply direction gradually converges, and the air supply distance can be farther. Therefore, the embodiment of the present disclosure can further extend the air deflector when the user is too far away from the indoor unit to appropriately increase the front air outlet volume and the air supply distance, thereby facilitating the user to feel comfortable air in time and further improving the user's air conditioner use experience.

[0266] Similarly, when the real-time distance between the user and the shell is less than the lower limit value of the preset distance range, it indicates that the user is too close to the indoor unit, and the heat exchange air sent through the front air outlet can easily reach the user's vicinity, and the user's anti-direct blowing experience is poor. Therefore, the disclosed embodiment can appropriately adjust the extension position of the air guide body to gradually approach the retracted position, thereby reducing the gap between the air guide body and the front air outlet. At this time, the air supply volume of the front air outlet gradually decreases, the air supply direction gradually diverges, and the air supply distance is relatively closer. Therefore, the disclosed embodiment can further retract the air guide body when the user is too close to the indoor unit, to appropriately reduce the front air outlet air volume and air supply distance, thereby facilitating the user's anti-direct blowing demand and further improving the user's air conditioner use experience.

[0267] Optionally, in the case that the user has an anti-direct blowing demand and the user is located in the air outlet range of the front air outlet, the control device further maintains the first extension position of the air guide body to maintain the gap between the air guide body and the front air outlet in the case that the real-time distance between the user and the shell is within the preset distance range.

[0268] In this way, when the real-time distance between the user and the shell is within the preset distance range, it indicates that the user is moderate distance from the indoor unit, and the heat exchange air sent through the front air outlet can reach the user's vicinity in time, but it does not affect the user's anti-direct blowing experience. Therefore, the disclosed embodiment can appropriately maintain the first extension position of the air guide body to maintain the gap between the air guide body and the front air outlet. At this time, the indoor unit can realize the front air outlet mode of small air volume, short distance, and divergent air supply, which is beneficial to better meet the user's anti-direct blowing demand and actual air supply demand, thereby improving the user's air conditioner use experience.

[0269] Based on the above indoor unit, in combination with Figure 33 The disclosed embodiment provides another control method for an indoor unit, which comprises:

[0270] S301, the control device acquires the indoor environment temperature difference.

[0271] S302, the control device determines whether the indoor environment temperature difference is greater than a preset environment temperature difference. If yes, the control device performs step S303; if no, the control device performs step S304.

[0272] S303, the control device controls the air guide body to move to the maximum extension position.

[0273] S304, the control device acquires indoor user information.

[0274] S305, the control device controls the extension position of the air guide body according to the indoor user information.

[0275] The control method for the indoor unit provided by the embodiment of the present disclosure can first acquire the indoor environment temperature difference to determine whether the indoor unit is currently in the early temperature adjustment stage or the late temperature stabilization stage. If the indoor environment temperature difference is greater than the preset environment temperature difference, it indicates that the indoor unit is in the early temperature adjustment stage, and the embodiment of the present disclosure can control the air deflector to move to the maximum extension position, so that the gap between the air deflector and the front air outlet is maximized, thereby realizing the front air outlet mode of large air volume, long distance and air gathering, which is beneficial to quickly reaching the indoor environment temperature to the target temperature set by the user, so as to more quickly create the indoor comfortable environment required by the user, and thus improve the air conditioner use experience of the user. If the indoor environment temperature difference is less than or equal to the preset environment temperature difference, it indicates that the indoor unit is in the late temperature stabilization stage, and the embodiment of the present disclosure further acquires the indoor user information to determine the actual air supply demand of the user, and then controls the air deflector to move to the appropriate extension position, thereby realizing the adaptive adjustment of the air volume, air direction, air speed, air supply distance and other parameters of the front air outlet, improving the diversity of the front air outlet mode of the indoor unit, which is beneficial to better meeting the actual air supply demand of the user, and thus improving the air conditioner use experience of the user.

[0276] Optionally, the control device acquires the indoor environment temperature difference, including: in the case that the indoor unit works in the cooling mode, the control device calculates the difference between the indoor environment temperature and the indoor target temperature to obtain a first indoor environment temperature difference; or in the case that the indoor unit works in the heating mode, the control device calculates the difference between the indoor target temperature and the indoor environment temperature to obtain a second indoor environment temperature difference.

[0277] In this way, the embodiment of the present disclosure can acquire the indoor environment temperature difference in combination with the operation mode of the indoor unit to obtain the first indoor environment temperature difference in the cooling mode or the second indoor environment temperature difference in the heating mode, thereby being beneficial to accurately determining whether the indoor unit is currently in the early temperature adjustment stage or the late temperature stabilization stage in the cooling mode or the heating mode, and thus reasonably adjusting the front air outlet mode of the indoor unit, which is beneficial to better meeting the actual air supply demand of the user.

[0278] Optionally, after the control device determines whether the indoor environment temperature difference is greater than the preset environment temperature difference, the method further includes: in the case that the indoor environment temperature difference is greater than the preset environment temperature difference, controlling the air deflector to move to the maximum opening position.

[0279] In this way, when the indoor environment temperature difference is greater than the preset environment temperature difference, it indicates that the indoor unit is in the early temperature adjustment stage, and the embodiment of the present disclosure can control the air deflector to move to the maximum opening position, so that the air outlet areas of the first side air outlet and the second side air outlet are maximized, thereby realizing the side air outlet mode of large air volume and long distance, which is beneficial to quickly reaching the indoor environment temperature to the target temperature set by the user, so as to more quickly create the indoor comfortable environment required by the user, and thus improve the air conditioner use experience of the user.

[0280] Based on the above indoor unit, combined with Figure 34 The embodiment of the disclosure provides another control method for an indoor unit, which comprises the following steps:

[0281] In S401, the control device acquires indoor user information.

[0282] In S402, the control device controls the extension position of the air guide body according to the indoor user information.

[0283] In 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.

[0284] The control method for the indoor unit provided by the embodiment of the disclosure can first acquire indoor user information to determine the actual air supply demand of the user, and then control the air guide body to move to a suitable extension position, so as to adaptively adjust the parameters such as the air volume, air direction, air speed and air supply distance of the front air outlet, improve the diversity of the front air outlet mode of the indoor unit, better meet the actual air supply demand of the user, and further improve the air conditioner use experience of the user. Then, the embodiment of the disclosure can consider the fan surge problem caused by the airflow accumulation in the first air duct, adaptively adjust the working position of the baffle according to the internal air pressure of the first air duct under different extension positions of the air guide body, reasonably adjust the opening area of the air vent, so as to appropriately discharge part of the heat exchange air in the first air duct through the air vent, further realize the pressure relief function, reduce the risk of fan surge, improve the operation reliability of the indoor unit, and further improve the use experience of the user.

[0285] 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 air vent, which comprises: the control device searches for the target working position of the baffle corresponding to the current extension position of the air guide body from the preset correlation relationship; and the control device controls the baffle to move to the target working position to adjust the opening area of the air vent.

[0286] In this way, the embodiment of the disclosure can pre-construct the preset correlation relationship between the extension position of the air guide body and the working position of the baffle. Then, by searching for the target working position of the baffle corresponding to the current extension position of the air guide body in the preset correlation relationship, the baffle is quickly controlled to move to a more suitable target working position to reasonably adjust the opening area of the air vent, so as to appropriately discharge part of the heat exchange air in the first air duct through the air vent, further realize the pressure relief function, reduce the risk of fan surge, improve the operation reliability of the indoor unit, and further improve the use experience of the user.

[0287] Optionally, the greater the gap between the air guide body at the current extension position and the front air outlet, the smaller the opening area of the air vent when the baffle is at the target working position.

[0288] In this way, as the air guide body continuously extends, the gap between the air guide body and the front air outlet gradually increases, the air outlet area of the front air outlet gradually increases, and the static pressure in the first air duct gradually decreases. At this time, the baffle is linked to gradually reduce the opening area of the air vent, so that the pressure relief flow is reduced synchronously. In this way, the air duct pressure can be kept stable during the movement of the air guide body, avoiding excessive pressure relief or air leakage to cause energy waste, and ensuring that the front side annular narrow gap always obtains sufficient wind speed and range, achieving a dynamic balance of comfort, energy saving and safety.

[0289] Optionally, the preset association relationship includes a corresponding relationship between the extension positions of the one or more air guide bodies and the working positions of the baffle. For example, when the air guide body is located at a first extension position, the control device determines that the baffle is located at a first working position; when the air guide body is located at a second extension position, the control device determines that the baffle is located at a second working position; when the air guide body is located at a third extension position, the control device determines that the baffle is located at a third working position; and when the air guide body is located at a fourth extension position, the control device determines that the baffle is located at a fourth working position.

[0290] Optionally, the first opening area of the air vent when the baffle is at the first working position is greater than the second opening area of the air vent when the baffle is at the second working position. The third opening area of the air vent when the baffle is at the third working position is less than the fourth opening area of the air vent when the baffle is at the fourth working position.

[0291] In this way, the air duct pressure can be kept stable during the movement of the air guide body.

[0292] Optionally, the control method for the indoor unit further includes: the control device acquires 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 adjusts the working position of the baffle to increase the opening area of the air vent.

[0293] In this way, if the internal air pressure of the first air duct continues to rise and reaches the pressure threshold due to reasons such as filter screen blockage and air outlet obstruction, the air supply of the front air outlet 1 will be affected and the fan may be surging, resulting in increased noise. At this time, the baffle reopens or expands the air vent area. In this way, secondary pressure relief can be achieved to effectively prevent fan overload, noise surge or system protection shutdown, while avoiding damage to internal components caused by long-term high pressure, further improving the safety and service life of the entire machine.

[0294] Based on the above indoor unit, in combination with Figure 35 The embodiment of the present disclosure provides another control method for an indoor unit, which includes:

[0295] S501, the control device acquires indoor user information.

[0296] S502, the control device controls the extension position of the air deflector according to the indoor user information.

[0297] S503, the control device controls the opening position of the air deflector according to the indoor user information.

[0298] The control method for the indoor unit provided by the embodiments of the present disclosure can first acquire indoor user information to determine the actual air supply demand of the user, then control the air deflector to move to a suitable extension position and synchronously control the air deflector to move to a suitable opening position, so as to realize adaptive adjustment of the front air outlet air supply parameter and the side air outlet air supply parameter, to cooperatively optimize the front air outlet effect and the side air outlet effect of the indoor unit, improve the diversity of the air outlet mode of the indoor unit, and be conducive to better meeting the actual air supply demand of the user, and further improve the air conditioner use experience of the user.

[0299] Optionally, the control device controls the opening position of the air deflector according to the indoor user information, including: in the case that the user has a direct blowing prevention demand and the user is located in the air outlet range of the first side air outlet and / or the second side air outlet, the control device controls the air deflector to move to a first opening position; or in the case that the user has no direct blowing prevention demand and the user is located in the air outlet range of the first side air outlet and / or the second side air outlet, the control device controls the air deflector to move to a second opening position; or in the case that the user has a direct blowing prevention demand and the user is not located in the air outlet range of the first side air outlet and / or the second side air outlet, the control device controls the air deflector to move to a third opening position; or in the case that the user has no direct blowing prevention demand and the user is not located in the air outlet range of the first side air outlet and / or the second side air outlet, the control device controls the air deflector to move to a fourth opening position.

[0300] Wherein, the first air outlet area of the first side air outlet and / or the second side air outlet when the air deflector is in the first opening position is less than the second air outlet area of the first side air outlet and / or the second side air outlet when the air deflector is in the second opening position. The third air outlet area of the first side air outlet and / or the second side air outlet when the air deflector is in the third opening position is less than the fourth air outlet area of the first side air outlet and / or the second side air outlet when the air deflector is in the fourth opening position.

[0301] Thus, when the user has the anti-direct-blowing requirement and the user is located in the air outlet range of the first side air outlet and / or the second side air outlet, it indicates that the side air outlet mode of the indoor unit affects the user's comfort feeling and is not conducive to meeting the actual air supply requirement of the user. Therefore, the embodiment of the present disclosure can control the air deflector to move to the first open position close to or at the closed position, at which the air deflector is opened at a small angle, the first air outlet area corresponding to the first side air outlet and / or the second side air outlet is relatively small, the air supply volume of the side air outlet is relatively small, and the air supply direction is away from the user for air supply, so as to reduce the adverse effect of the side air outlet mode on the user's comfort feeling. Thus, by controlling the air deflector to move to the more appropriate first open position when the user has the anti-direct-blowing requirement and the user is located in the air outlet range of the first side air outlet and / or the second side air outlet, the embodiment of the present disclosure can realize the side air outlet mode of small air volume and away from the user for air supply, which is conducive to better meeting the anti-direct-blowing requirement and the actual air supply requirement of the user, and thus improves the air conditioner use experience of the user.

[0302] Similarly, when the user has no anti-direct-blowing requirement and the user is located in the air outlet range of the first side air outlet and / or the second side air outlet, it indicates that the side air outlet mode of the indoor unit will not affect the user's comfort feeling, and is even more conducive to meeting the actual air supply requirement of the user. Therefore, the embodiment of the present disclosure can control the air deflector to move to the second open position close to or at the maximum open position, at which the air deflector is opened at a large angle, the first air outlet area corresponding to the first side air outlet and / or the second side air outlet is relatively large, the air supply volume of the side air outlet is relatively large, and the air supply direction is toward the user for air supply, so as to improve the beneficial effect of the side air outlet mode on the user's comfort feeling. Thus, by controlling the air deflector to move to the more appropriate second open position when the user has no anti-direct-blowing requirement and the user is located in the air outlet range of the first side air outlet and / or the second side air outlet, the embodiment of the present disclosure can realize the side air outlet mode of large air volume and toward the user for air supply, which is conducive to better meeting the direct-blowing requirement and the actual air supply requirement of the user, and thus improves the air conditioner use experience of the user.

[0303] 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.

[0304] 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 indoor unit's side airflow mode 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.
