[0102] Embodiments of this disclosure are described in detail below, with examples of these embodiments illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this disclosure, and should not be construed as limiting it.

[0103] As shown in Figure 1, the indoor unit of the air conditioner in this embodiment of the present disclosure includes a frame 10, a base 11, a heat exchanger 13, an air guide 14, and a cross-flow assembly 15.

[0104] The frame 10 is provided with an air inlet 101 and an air outlet 102, and the air outlet 102 is located above the air inlet 101 during use. For example, as shown in Figure 1, the frame 10 can be a one-piece injection molded part, and both the air inlet 101 and the air outlet 102 can be provided on the frame 10 by one-piece injection molding.

[0105] When the indoor unit of the air conditioner is installed on the wall, the air inlet 101 can be located on the bottom side of the frame 10, and the air outlet 102 can be located on the front top side of the frame 10. In use, air can be drawn in through the air inlet 101 and then discharged through the air outlet 102, thus meeting the needs of bottom air intake and top air discharge.

[0106] The base 11 is connected to the frame 10, and an air duct 12 extending along a first direction is defined between the base 11 and the frame 10. The base 11 and the frame 10 are arranged opposite each other in a second direction orthogonal to the first direction.

[0107] For example, as shown in Figure 1, the base 11 can be arranged vertically and can be located on the rear side of the frame 10. After the base 11 and the frame 10 are installed and fixed, the base 11 and the frame 10 can form an internal space, which can be regarded as the air duct 12. The air duct 12 can be roughly L-shaped. The bottom end of the air duct 12 is connected to the air inlet 101, and the front end of the air duct 12 is connected to the air outlet 102.

[0108] It should be noted that, as shown in Figures 1 and 2, in this embodiment, the first direction can be the left-right direction, the second direction can be the front-back direction, and the base 11 and the frame 10 can be arranged opposite to each other and connected and fixed in the front-back direction.

[0109] The heat exchanger 13 is disposed within the air duct 12, adjacent to and protruding from the air inlet 101, and serves as either an evaporator or a condenser. For example, as shown in FIG1, the heat exchanger 13 can be entirely assembled within the air duct 12. When cooling is required, the heat exchanger 13 can be used as an evaporator. In some other embodiments, the heat exchanger 13 can also be used as a condenser, for example, when heating is required.

[0110] The heat exchanger 13 can be a V-shaped structure. For example, the heat exchanger 13 can be composed of two independent plate heat exchangers 13, and the connection between the two plate heat exchangers 13 can protrude downward and be arranged directly opposite the air inlet 101 in the vertical direction.

[0111] Therefore, on the one hand, it facilitates the collection of condensate and other substances on the heat exchanger 13; on the other hand, this downward protruding design can achieve the effect of diversion, that is, the airflow at the air inlet 101 can be diverted to the front and rear sides of the heat exchanger 13 respectively, which helps to slow down the airflow velocity and thus improve the overall heat exchange effect. Secondly, it can also play a certain role in noise reduction.

[0112] The air guide 14 is connected to the base 11 and positioned adjacent to the air outlet 102, and is used to guide the airflow in the air duct 12 to the air outlet 102. For example, as shown in Figure 1, the air guide 14 can be installed on the front side of the base 11 and can be located at the top of the indoor unit of the air conditioner. The air guide 14 can be a hollow structure, and the hollow interior of the air guide 14 can connect the air duct 12 and the air outlet 102, thereby guiding the airflow flowing out of the air duct 12 to the air outlet 102.

[0113] The cross-flow assembly 15 is disposed in the air duct 12 and is located between the air guide frame 14 and the heat exchanger 13 in the third direction. The third direction is perpendicular to the first direction and the second direction, and the cross-flow assembly 15 is used to transport airflow from the air inlet 101 to the air outlet 102.

[0114] For example, as shown in Figure 1, the cross-flow assembly 15 may include a cross-flow fan 151 that drives the fan blades to rotate, and the cross-flow fan 151 of the cross-flow assembly 15 may also be installed in the air duct 12. The aforementioned third direction can be the vertical direction, in which the fan of the cross-flow assembly 15 can be located in the space of the air duct 12 between the air guide frame 14 and the heat exchanger 13.

[0115] In use, the cross-flow assembly 15 can drive the fan blades to rotate, thereby meeting the need to draw in external air from the air inlet 101 and exchange heat with the heat exchanger 13, and then discharge it through the air guide frame 14 and the air outlet 102.

[0116] The air conditioner indoor unit of this embodiment adopts a bottom air intake and top air outlet design, which can basically achieve ceiling installation. This avoids the situation in the prior art where the impact of ceiling installation on air intake needs to be considered when the air intake is top air intake. It also reduces the installation distance between the air conditioner indoor unit and the ceiling and improves the appearance of the installation.

[0117] Secondly, since the indoor unit of the air conditioner can be installed on a higher wall, the downward viewing angle of the indoor unit is increased, which in turn can improve the air delivery range of the indoor unit. In addition, the design of the heat exchanger 13 protruding towards the air inlet 101 can achieve the effect of air diversion, which helps to improve the overall heat exchange efficiency and also helps to reduce air intake noise.

[0118] In some embodiments, the indoor unit of the air conditioner also includes a mounting base 16 and a swing motor 171. The air guide frame 14 is provided with a receiving cavity 141. The mounting base 16 is detachably mounted on the air guide frame 14 and arranged opposite to the receiving cavity 141. The swing motor 171 is detachably mounted on the mounting base 16, and at least a portion of the motor is embedded in the receiving cavity 141.

[0119] As shown in Figure 2, the air guide frame 14 is provided with a receiving cavity 141. For example, as shown in Figure 2, the material of the air guide frame 14 can be plastic, etc. The air guide frame 14 can be integrally injection molded and can extend along the left and right directions. The receiving cavity 141 can be a groove-shaped structure integrally formed on the air guide frame 14, and the receiving cavity 141 can be located on the left side of the air guide frame 14.

[0120] The mounting base 16 is detachably mounted on the air guide frame 14 and arranged opposite to the receiving cavity 141. For example, as shown in Figure 2, the mounting base 16 can be made of plastic or the like. The mounting base 16 can be integrally injection molded. The mounting base 16 can be mounted on the rear side of the air guide frame 14 by means of screw fixing, snap-fit, etc. In the front-back direction, the receiving cavity 141 can be located in front of the mounting base 16, so that the mounting base 16 can block the rear side of the receiving cavity 141.

[0121] The sweeping motor 171 is detachably mounted on the mounting base 16, with at least a portion of the sweeping motor 171 embedded within the receiving cavity 141. For example, as shown in Figure 2, the sweeping motor 171 can be a stepper motor, or it can be part of the sweeping assembly 17. The sweeping motor 171 can be fixed to the front side of the mounting base 16 by means of screws, snap-fit, or other methods, and the entire sweeping motor 171 can be inserted into the receiving cavity 141, as shown in Figure 3. This facilitates the installation and fixing of the sweeping motor 171, achieves a proper fit between the air guide frame 14 and the sweeping motor 171, and also provides protection for the sweeping motor 171.

[0122] It should be noted that the sweeping motor 171 can also be connected to multiple sweeping plates 174 through a corresponding transmission mechanism. In use, the rotation of the sweeping motor 171 can drive multiple sweeping plates 174 to swing synchronously, thereby realizing the adjustment of air outlet direction, soft wind mode (at this time, micro-holes for airflow to pass through need to be evenly distributed on each sweeping plate 174).

[0123] In this embodiment of the air conditioner indoor unit, the air guide frame 14 and the mounting base 16 are separately arranged, which facilitates the processing of the film on the mounting base 16 and improves the convenience of installation and disassembly.

[0124] In some embodiments, the air guide frame 14 is connected to the mounting base 16 by a first fastener. One of the air guide frame 14 and the mounting base 16 is provided with a plurality of first columns 142 connected to the first fastener, and the other is provided with a plurality of first holes 161 through which the first fastener passes.

[0125] For example, as shown in Figure 3, the first column 142 can be integrally formed on the air guide frame 14. The first column 142 can be cylindrical, and the interior of the first column 142 can be provided with threaded holes. As shown in Figures 4 and 5, the first hole 161 can be a circular hole, and the first hole 161 can penetrate the mounting base 16 along the thickness direction of the mounting base 16.

[0126] The first fastener can be a screw or the like. During assembly, the first fastener can be passed through the first hole 161 and threaded onto the first column 142, thereby ensuring the structural stability of the connection between the air guide frame 14 and the mounting base 16.

[0127] In some embodiments, the first column 142 is disposed on the air guide frame 14, and the mounting base 16 is provided with a plurality of first protrusions 162. The first protrusions 162 protrude into the inner side of the mounting base 16 and form a groove on the outer side of the mounting base 16 away from the base 11. The first column 142 is inserted into the groove, and the first hole 161 is disposed on the bottom wall of the groove.

[0128] For example, as shown in Figure 3, there can be two first pillars 142. Both first pillars 142 can be integrally formed on the air guide frame 14 by injection molding, and both first pillars 142 can be located on the rear side of the air guide frame 14.

[0129] As shown in Figure 4, the mounting base 16 may be provided with two first bosses 162. Both first bosses 162 can be integrally formed on the mounting base 16 by injection molding. The first bosses 162 can be arched. Each first boss 162 can protrude to the rear side of the mounting base 16 and can be restricted to the front side of the mounting base 16. Each first boss 162 may be provided with a first hole 161.

[0130] During assembly, the two first pillars 142 on the air guide frame 14 can be inserted into the grooves of the two first protrusions 162 in a one-to-one correspondence, thereby enhancing the limiting constraint effect between the air guide frame 14 and the mounting base 16. Secondly, the setting of the first protrusions 162 can also enhance the structural strength of the mounting base 16.

[0131] In some embodiments, the mounting base 16 includes a first plate portion 163 and a second plate portion 164 that are staggered in the inward and outward directions, and both the first plate portion 163 and the second plate portion 164 are provided with a first boss 162.

[0132] For example, as shown in Figure 4, both the first plate portion 163 and the second plate portion 164 can be flat, wherein the dimensions of the first plate portion 163 are larger than those of the second plate portion 164. A first boss 162 can be integrally formed on both the first plate portion 163 and the second plate portion 164.

[0133] The mounting base 16 can also be positioned in a front-to-back direction, with the first plate portion 163 located in front of the second plate portion 164. During assembly, the first plate portion 163 can be arranged opposite to the rear opening of the receiving cavity 141, and the second plate portion 164 can overlap the peripheral portion of the opening of the receiving cavity 141, thereby enhancing the limiting and restraining effect of the mounting base 16 and the air guide frame 14. In some embodiments, one of the air guide frame 14 and the mounting base 16 is provided with a buckle, and the other is provided with a first slot 143, with the buckle engaging in the first slot 143.

[0134] For example, the buckle can be integrally formed on the mounting base 16, specifically located at the outer peripheral edge of the first plate portion 163. As shown in Figure 3, the first slot 143 can be provided on the air guide frame 14, and the first slot 143 can be located within the receiving cavity 141.

[0135] During assembly, the mounting base 16 and the air guide frame 14 can be pre-positioned and pre-fixed by the snap-fit ​​and the first slot 143. Then, the air guide frame 14 and the mounting base 16 can be connected and fixed by screws, which can improve assembly efficiency and enhance the structural stability of the assembly of the air guide frame 14 and the mounting base 16.

[0136] In some embodiments, the air guide frame 14 is detachably mounted on the base 11. The air guide frame 14 extends along a first direction and is provided with a recess 144. The recess 144 is provided at at least one end of the air guide frame 14 in the first direction and is used to avoid the drive mechanism 18 that drives the air guide plate to move.

[0137] For example, as shown in Figure 5, the air guide frame 14 can extend along the left and right direction as a whole, and both the left and right ends of the air guide frame 14 can be integrally formed with recesses 144. The recesses 144 can be steps, grooves or other structures, and the recesses 144 can be recessed to the rear.

[0138] The drive mechanism 18 may include a motor, a transmission mechanism, etc. The air guide plate may be located on the front side of the air guide frame 14 and connected to the drive mechanism 18. The drive mechanism 18 can drive the air guide plate to swing, thereby facilitating the opening and closing of the air outlet 102 or adjusting the size of the air outlet 102. The drive mechanism 18 may be located on the front side of the recess 144, and the motor or transmission mechanism may be fitted into the recess 144, thereby avoiding assembly interference between the drive mechanism 18 and the air guide frame 14.

[0139] The air conditioner indoor unit of this embodiment can also improve the fit with the drive mechanism 18 by providing a recess 144 on the air guide 14, and can improve the fit with the motor by providing a receiving cavity 141 on the air guide 14, thereby increasing the compactness of the assembly and improving the overall space utilization.

[0140] In some embodiments, one of the base 11 and the air guide frame 14 is provided with a first insertion hole 111, and the other is provided with a first insertion part 146. The first insertion part 146 is inserted into the first insertion hole 111 to realize the insertion assembly of the base 11 and the air guide frame 14.

[0141] For example, as shown in Figure 5, the first insertion hole 111 can be located on the top of the base 11 and at the front of the base 11. As shown in Figure 10, the first insertion part 146 can be integrally formed on the top of the air guide frame 14 and located at the rear of the air guide frame 14. During assembly, the first insertion part 146 on the air guide frame 14 can be directly inserted into the first insertion hole 111, thereby achieving pre-fixation of the air guide frame 14 and the base 11, which helps to improve assembly efficiency.

[0142] In some embodiments, the base 11 and the air guide frame 14 are connected by a third fastener, and the base 11 is provided with a third column 112 connected to the third fastener, and the air guide frame 14 is provided with a first fixing hole 147 for the third fastener to pass through.

[0143] In some embodiments, as shown in FIG6, the indoor unit of the air conditioner includes a motor cover 19, which is arranged opposite to the recess 144 in a second direction orthogonal to the first direction. One of the motor cover 19 and the air guide frame 14 is provided with a second insertion hole 148, as shown in FIG7, and the other is provided with a second insertion part 191. The second insertion part 191 is inserted into the second insertion hole 148 to realize the insertion assembly of the air guide frame 14 and the motor cover 19.

[0144] In some embodiments, the motor cover 19 and the air guide frame 14 are connected by a fourth fastener, and the motor cover 19 is provided with a fourth column 192 connected to the fourth fastener, and the air guide frame 14 is provided with a second fixing hole 149 for the fourth fastener to pass through, as shown in FIG7.

[0145] In some embodiments, as shown in FIG6, the indoor unit of the air conditioner includes a heat exchanger 13. The heat exchanger 13 is provided with a heat exchanger bracket 131 at its end in a first direction. One of the heat exchanger bracket 131 and the air guide bracket 14 is provided with a third insertion hole 1410, and the other is provided with a third insertion part 1311. The third insertion part 1311 is inserted and fitted into the third insertion hole 1410, as shown in FIG6 and FIG7.

[0146] During assembly, the third insertion part 1311 can be inserted into the third insertion hole 1410, thereby realizing the insertion and assembly of the air guide frame 14 and the heat exchanger 13, achieving pre-positioning and pre-fixation of the two.

[0147] In some embodiments, the heat exchanger bracket 131 and the air guide frame 14 are connected by a fifth fastener, and the heat exchanger bracket 131 is provided with a fifth column 1312 connected to the fifth fastener, and the air guide frame 14 is provided with a third fixing hole 1411 for the fifth fastener to pass through, as shown in Figures 6 and 7.

[0148] In some embodiments, as shown in FIG8, the air-sweeping assembly 17 of this disclosure includes a plurality of air-sweeping plates 174 and a connecting rod 173. Each air-sweeping plate 174 may be rectangular, and each air-sweeping plate 174 may have a plurality of through holes evenly distributed thereon.

[0149] Multiple air-sweeping plates 174 can be arranged at equal intervals in the left and right directions, and the multiple air-sweeping plates 174 can be set in parallel. That is, any one of the multiple air-sweeping plates 174 can be obtained by moving the other air-sweeping plates 174 in the left and right directions.

[0150] Each air-sweeping plate 174 is provided with a first swing rod 175 for driving the air-sweeping plate 174 to rotate. A connecting rod 173 extends along a first direction, and the connecting rod 173 is rotatably connected to the first swing rods 175 of the multiple air-sweeping plates 174. For example, each air-sweeping plate 174 can be made of plastic, and each air-sweeping plate 174 can be provided with a first swing rod 175 by integral injection molding, and the extension direction of the first swing rod 175 can form an angle with the plane of the air-sweeping plate 174.

[0151] The connecting rod 173 can also be made of plastic or other materials. The connecting rod 173 can be straight and can extend in the left and right direction. The connecting rod 173 can be located on the same side of multiple air sweeping plates 174. One end of each first swing rod 175 can be located at the rotation axis of the air sweeping plate 174 and fixedly connected to the air sweeping plate 174. The other end of each first swing rod 175 can be rotatably connected to the connecting rod 173.

[0152] One end of the drive shaft 172 is rotatably connected to the end of the connecting rod 173, and the other end of the drive shaft 172 is connected to the drive shaft of the sweeping motor 171. For example, as shown in Figures 8 and 9, the drive shaft 172 can be in the shape of a short rod. One end of the drive shaft 172 can be pivotally assembled to the left end of the connecting rod 173, and the other end of the drive shaft 172 can be fixedly connected to the drive shaft of the sweeping motor 171, wherein the sweeping motor 171 can be a stepper motor, etc.

[0153] In use, the sweeping motor 171 can drive the drive shaft 172 to swing left and right. For example, when the drive shaft 172 swings to the left, the connecting rod 173 can move to the left, at which time the multiple sweeping blades 174 can swing to a position perpendicular to the left and right directions, and the multiple sweeping blades 174 switch to the forward air outlet state, as shown in Figure 8. When the drive shaft 172 swings to the right, the connecting rod 173 can move to the right, at which time the multiple sweeping blades 174 can swing to the side air outlet position.

[0154] It should be noted that, as shown in Figures 9(a) and 9(b), the length of the first swing rod 175 of each sweeping plate 174 can be the same, and multiple first swing rods 175 can be arranged in parallel intervals in the left and right directions. Thus, any two adjacent first swing rods 175 can form a parallelogram structure, as can be seen in parallelograms CDEF and EFHG in Figures 9(a) and 9(b), thereby ensuring the synchronicity of the swing of multiple sweeping plates 174.

[0155] The length of the drive shaft 172 is greater than the length of the first swing arm 175. For example, as shown in Figure 9, the length of the drive shaft 172 can be L1, and the length of the first swing arm 175 can be L2, with L1 being greater than L2. Therefore, when the drive shaft 172 swings around point B in Figure 9, it increases the lever arm length between points A and B, thereby increasing the force applied to the connecting rod 173 at point A, and ultimately enabling the multiple air-sweeping plates 174 to be completely flattened and closed.

[0156] The sweeping assembly 17 of this embodiment increases the lever arm by increasing the length of the drive shaft 172, thereby increasing the force applied to the connecting rod 173 at point A. This allows the connecting rod 173 to push to the right under a larger force, avoiding the situation in the prior art where the connecting rod 173 is long and the force is small, resulting in a large difference in the rotation angle between some sweeping plates 174 on the right side and some sweeping plates 174 on the left side. This ensures the consistency of the rotation adjustment range of multiple sweeping plates 174, allowing multiple sweeping plates 174 to be completely closed and leveled.

[0157] In some embodiments, as shown in FIG9, the connecting rod 173 includes a first rod 1731 and a second rod 1732. Both the first rod 1731 and the second rod 1732 extend along a first direction. A plurality of first swing rods 175 are rotatably connected to the first rod 1731. One end of the second rod 1732 is connected to the first rod 1731, and the other end of the second rod 1732 is rotatably connected to the drive shaft 172.

[0158] Since the assembly of the sweeping motor 171 and the multiple sweeping plates 174 of the sweeping assembly 17 can be carried out separately, the split design of the connecting rod 173 meets the needs of separate installation. After the two parts of the air guide assembly are installed separately, the first rod 1731 and the second rod 1732 can be connected and fixed, which facilitates the assembly.

[0159] In some embodiments, the air duct 12 can be installed on or integrally formed on the front side of the base 11 of the air conditioner indoor unit. The air duct 12 can generally extend in the vertical direction and can generally extend in the horizontal direction, that is, the length direction of the air duct 12 can be the horizontal direction.

[0160] The inner wall surface of the air duct 12 is provided with a protrusion 121 or at least two protrusions 121, the at least two protrusions 121 are arranged at intervals along a third direction, the protrusions 121 extend along a first direction orthogonal to the third direction, and the protrusions 121 are used to change the flow direction of the condensate flowing along the inner wall surface so that the condensate can be discharged to the heat exchanger 13 located below the air duct 12.

[0161] For example, as shown in Figure 10, the protrusion 121 can specifically be a ridge. The protrusion 121 can be integrally formed on the inner wall surface of the air duct 12, wherein the inner wall surface is the front wall surface of the air duct 12 in Figure 10. There may be only one protrusion 121. In some other embodiments, there may be two, three, four, or other protrusions 121. In this case, multiple protrusions 121 can be arranged at intervals along the vertical direction, and each protrusion 121 can extend along the horizontal direction.

[0162] During assembly, as shown in Figure 10, the heat exchanger 13 of the indoor unit of the air conditioner can be installed on the front side of the air duct 12 and located at the bottom of the air duct 12. The aforementioned protrusions 121 can all be located above the heat exchanger 13.

[0163] In use, outside air can flow from the air inlet 101 at the bottom of the indoor unit of the air conditioner through the air duct 12 and the heat exchanger 13, and then be discharged from the air outlet 102 at the top and front of the indoor unit. Since the cavity inside the air duct 12 is a cold cavity during use, water vapor and other substances inside the air duct 12 will condense and liquefy to form condensate. The condensate will adhere to the inner wall of the air duct 12 and flow from top to bottom.

[0164] Because the inner wall of the air duct 12 is provided with multiple protrusions 121, the multiple protrusions 121 can act like eaves, that is, the protrusions 121 can guide and change the flow direction of condensate, thus facilitating the dripping of condensate onto the heat exchanger 13, and finally into the water collection pan at the bottom of the evaporator.

[0165] The air duct 12 of this embodiment is provided with a plurality of protrusions 121. The protrusions 121 can play a guiding role, thereby preventing condensate from dripping onto the outside of the heat exchanger 13 and facilitating the collection of condensate.

[0166] Secondly, the protrusion 121 can also enhance the overall structural strength of the air duct 12, that is, the protrusion 121 can act as a reinforcing rib, thus fully meeting the needs of use.

[0167] In some embodiments, the inner wall surface of the air duct 12 is provided with a plurality of air duct curved surfaces 122, the plurality of air duct curved surfaces 122 are arranged at intervals along a third direction, and the protrusion 121 is provided between two adjacent air duct curved surfaces 122.

[0168] For example, as shown in Figure 10, three air duct surfaces 122 can be provided on the inner wall surface. The three air duct surfaces 122 can be arranged sequentially in the vertical direction, and a protrusion 121 can be provided between every two adjacent air duct surfaces 122. The protrusion 121 is a convex ridge and can be constructed by designing two adjacent air duct surfaces 122 with different curvatures.

[0169] In use, condensate can flow sequentially from top to bottom through each curved surface 122 of the air duct, facilitating the downward flow of condensate, reducing wind resistance, and promoting airflow. In some embodiments, the indoor unit of the air conditioner includes a sweeping assembly 17, and the frame 10 is provided with multiple mounting points 103 for connecting to the air guide bracket 14. For example, the top side of the frame 10 may have three mounting points 103, as shown in Figure 11. The mounting points 103 can be hole structures. During assembly, the air guide bracket 14 can be connected and fixed to the frame 10 by fasteners such as screws, and the three fasteners are respectively assembled at the three hole structures.

[0170] The air sweeping assembly 17 is located on the side of the frame 10 facing the panel 24. For example, the side of the frame 10 facing the panel 24 can be the front side of the frame 10, and the air sweeping assembly 17 can generally be located on the front side of the frame 10.

[0171] As shown in Figure 1, the air-sweeping assembly 17 includes an air-sweeping seat 177, which is detachably mounted on the frame 10. For example, the air-sweeping seat 177 can be fixed to the front side of the frame 10 by snap-fit. The air-sweeping seat 177 can be generally flat. After the air-sweeping seat 177 is assembled and fixed, the above-mentioned multiple mounting points 103 can be covered and hidden by the air-sweeping seat 177, thereby avoiding the exposure of the mounting points 103 and fasteners.

[0172] By matching and installing the air sweeping assembly 17 on the frame 10, the air sweeping mount 177 of the air sweeping assembly 17 can cover and hide multiple mounting points 103, avoiding exposure and improving the overall appearance and user experience.

[0173] The indoor unit of the air conditioner in this embodiment of the present disclosure also includes a heat exchanger bracket 131. The heat exchanger bracket 131 includes a bracket body 133, a fixing part 134, a water guiding part 135, and a wiring part 137. The fixing part 134 is provided on the bracket body 133 for passing through the metal pipe on the heat exchanger 13. The water guiding part 135 and the fixing part 134 are both provided on the side of the bracket body 133 away from the heat exchanger 13. The water guiding part 135 extends toward the lower end of the bracket body 133. The wiring part 137 is provided on the bracket body 133 and is used to fix the wire harness.

[0174] According to the embodiments of the present disclosure, the heat exchanger bracket 131 of the air conditioner indoor unit has a fixing part 134 for passing through the metal pipe of the heat exchanger 13, and both the water guiding part 135 and the fixing part 134 are located on the side of the bracket body 133 away from the heat exchanger 13. Therefore, the condensate accumulated at the fixing part 134 can be gradually guided towards the lower end of the bracket body 133 through the water guiding part 135, thus avoiding the problem of disorderly dripping condensate causing water leakage in the air conditioner indoor unit. On the other hand, since the wiring part 137 is located on the bracket body 133 and is used to fix the wiring harness, the problem of the wiring harness swaying relative to the heat exchanger bracket 131 can be avoided, which helps to reduce electrical safety hazards. Therefore, the heat exchanger bracket 131 of the air conditioner indoor unit of the embodiments of the present disclosure can not only fix the heat exchanger 13, but also has the functions of water guiding and wiring, and its integration level is high.

[0175] In some embodiments, the water guiding part 135 includes a baffle plate 1351, which protrudes from the side of the support body 133 away from the heat exchanger 13. The baffle plate 1351 is located on the outer edge of the support body 133 and gradually extends towards the lower end of the support body 133. It is understood that when the heat exchanger 13 is operating, condensate will accumulate at the location where the metal pipe passes through the fixing part 134. Since the baffle plate 1351 is located on the outer edge of the support body 133, the condensate accumulated at the fixing part 134 and the end of the metal pipe can drip onto the baffle plate 1351. A drip tray 26 is typically provided below the heat exchanger support 131. The baffle plate 1351 can guide the condensate downwards to the drip tray 26, thereby preventing the air conditioner indoor unit from leaking due to condensate dripping directly downwards.

[0176] Therefore, the heat exchanger bracket 131 of the embodiments of this disclosure can guide the condensate generated by the heat exchanger 13 during operation through the baffle 1351, thereby avoiding the problem of water leakage from the indoor unit of the air conditioner and improving the user experience.

[0177] In the example disclosed herein, the size of the baffle plate 1351 protruding from the support body 133 is larger than the size of the fixing part 134 protruding from the support body 133. It is understood that the extension length of the baffle plate 1351 is longer than the extension length of the fixing part 134, so that when condensate dripping downwards from the end of the fixing part 134, it can also be caught by the baffle plate 1351, further improving the water-blocking and flow-guiding effect of the heat exchanger support 131.

[0178] The ends of the metal tubes of heat exchanger 13 are located inside the fixing part 134. In other words, the ends of the metal tubes do not extend beyond the ends of the fixing part 134. On the one hand, this can prevent the metal tubes from being bumped during assembly; on the other hand, the condensate generated on the metal tubes can drip onto the support body 133 and the baffle plate 1351, thereby improving the condensate drainage effect.

[0179] Specifically, the fixing part 134 includes a first fixing part 1341 and a second fixing part 1342. The structure formed by the first fixing part 1341 and the second fixing part 1342 is V-shaped, with the tip of the V-shape facing downwards. The first fixing part 1341 is located on the front side of the second fixing part 1342. The baffle plate 1351 includes a first baffle plate 13511, which is located on the front side of the first fixing part 1341 and extends along the length of the first fixing part 1341. It should be noted that the front-rear direction of the heat exchanger bracket 131 is consistent with the front-rear direction of the air conditioner indoor unit. The front side of the first fixing part 1341 is the front side of the heat exchanger bracket 131.

[0180] Since the first fixing part 1341 and the second fixing part 1342 form a V-shaped structure with the tip pointing downwards, the length direction of the first fixing part 1341 gradually slopes downwards from front to back, and the first baffle plate 13511 also gradually slopes downwards from front to back. The first baffle plate 13511 is located on the front side of the first fixing part 1341, thereby guiding the condensate dripping from the first fixing part 1341.

[0181] In the example disclosed herein, the first baffle plate 13511 protrudes beyond the support body 133 by a larger dimension than the first fixing part 1341 protrudes beyond the support body 133. Therefore, when condensate dripping downwards from the end of the first fixing part 1341, it can also be caught by the first baffle plate 13511, further improving the water-blocking and flow-guiding effect of the heat exchanger support 131.

[0182] In some embodiments, the baffle plate 1351 further includes a second baffle plate 13512, which is disposed on the rear side of the second fixing portion 1342 and extends along the length direction of the second fixing portion 1342. Since the first fixing portion 1341 and the second fixing portion 1342 form a V-shaped structure with the tip pointing downwards, the length direction of the second fixing portion 1342 gradually slopes downwards from rear to front, and the second baffle plate 13512 also gradually slopes downwards from rear to front. In other words, the first baffle plate 13511 and the second baffle plate 13512 together form a V-shaped structure. The second baffle plate 13512 is disposed on the rear side of the second fixing portion 1342, thereby guiding the condensate dripping from the second fixing portion 1342.

[0183] In the example disclosed herein, the second baffle plate 13512 protrudes beyond the support body 133 by a larger dimension than the second fixing part 1342 protrudes beyond the support body 133. Therefore, when condensate dripping downwards from the end of the second fixing part 1342, it can also be caught by the second baffle plate 13512, further improving the water-blocking and flow-guiding effect of the heat exchanger support 131.

[0184] In some embodiments, the water guiding part 135 includes a water guiding plate 1352, which protrudes toward the side of the support body 133 away from the heat exchanger 13. The water guiding plate 1352 is inclined and extends downward along the front-back direction of the support body 133. It can be understood that the condensate collected on the outer wall surface of the support body 133 (the wall surface away from the heat exchanger 13) can flow downward to the position of the water guiding plate 1352. Under the guiding action of the water guiding plate 1352, the collected condensate can be guided to the lower end of the heat exchanger support 131 so that the condensate can fall into the water receiving tray 26. This can greatly reduce the probability of condensate dripping outside the water receiving tray 26 and improve the condensate guiding effect of the heat exchanger support 131.

[0185] For example, the water guide section 135 may be simply a water guide plate 1352. As another example, the air guide section may be simply a water baffle plate 1351.

[0186] In the example disclosed herein, the water guiding part 135 includes both a water guiding plate 1352 and a water baffle 1351. It is understood that, with the synergistic action of the water guiding plate 1352 and the water baffle 1351, the condensate on the fixing part 134 and the bracket body 133 can be guided to the lower end of the heat exchanger bracket 131, thereby further avoiding the problem of water leakage in the indoor unit of the air conditioner caused by disorderly dripping of condensate.

[0187] Specifically, the water inlet plate 1352 is disposed between the first fixing part 1341 and the second fixing part 1342. The upper end of the water inlet plate 1352 is arranged adjacent to the second fixing part 1342, and the lower end of the water inlet plate 1352 extends toward the tip of the V-shape of the heat exchanger support 131.

[0188] Understandably, the water guide plate 1352 primarily guides the condensate on the outer wall of the support body 133, while the baffle plates 1351 (first baffle plate 13511 and second baffle plate 13512) primarily guide the condensate generated on the fixing parts 134 (first fixing part 1341 and second fixing part 1342). That is, through the coordinated action of the water guide plate 1352 and the baffle plate 1351, the condensate on the fixing parts 134 and the support body 133 can be guided to the lower end of the heat exchanger support 131. This ensures that the condensate falls precisely into the water receiving tray 26, thereby greatly reducing the probability of condensate dripping outside the water receiving tray 26 and improving the condensate guiding effect of the heat exchanger support 131.

[0189] In some embodiments, the heat exchanger bracket 131 further includes a mounting platform 1381 for mounting the heater 251. The wiring section 137 includes a first wiring groove 1371. Both the first wiring groove 1371 and the mounting platform 1381 are located on the side of the bracket body 133 adjacent to the heat exchanger 13. At least a portion of the heating wires 252 of the heater 251 are arranged in the first wiring groove 1371, thereby avoiding the problem of the heating wires 252 swaying relative to the heat exchanger bracket 131.

[0190] Specifically, the indoor unit of the air conditioner also includes a heating module 25, which includes a heater 251 and a heating wire 252. The heater 251 and the electrical control assembly 20 are respectively arranged on both sides of the heat exchanger bracket 131 in the thickness direction. One end of the heating wire 252 is electrically connected to the heater 251 and is arranged adjacent to the heat exchanger bracket 131. The other end of the heating wire 252 is electrically connected to the electrical control assembly 20. The heating wire 252 is fixed on the wiring section 137.

[0191] Since one end of the heating wire 252 is electrically connected to the heater 251 and arranged near the heat exchanger bracket 131, and the other end of the heating wire 252 is electrically connected to the electrical control assembly 20, the outlet position of the heater 251 can be closer to the electrical control assembly 20, reducing the length of the heating wire 252. Furthermore, since the heating wire 252 is fixed on the wiring section 137, it can be secured to prevent the heating wire 252 from wobbling relative to the heat exchanger bracket 131. Therefore, the evaporation bracket of this embodiment reduces the length of the heating wire 252 and secures its arrangement, thereby reducing electrical safety hazards and lowering costs.

[0192] It is understandable that the outlet position of heater 251 is arranged near heat exchanger support 131. Since the electrical control assembly 20 is located on the other side of the thickness direction of heat exchanger support 131, the outlet position of heater 251 can be closer to the electrical control assembly 20, thereby reducing the arrangement length of heating wire 252. Compared with the solution of bypassing heat exchanger 13 or base 11, the arrangement length of heating wire 252 can be greatly reduced in this embodiment.

[0193] For example, the heating wire 252 can cross (bypass) or pass through the heat exchanger bracket 131 to connect to the electrical control assembly 20.

[0194] In some embodiments, the wiring section 137 includes a first wiring groove 1371, which is located on the side of the support body 133 adjacent to the heat exchanger 13. At least a portion of the heating wires 252 are arranged within the first wiring groove 1371. This allows the heating wires 252 arranged on the heat exchanger support 131 to be hidden, preventing interference between the heating wires 252 and other components (e.g., the impeller 152), and reducing the wiring space for the heating wires 252. It should be noted that the extension path of the first wiring groove 1371 can be designed according to the arrangement path of the heating wires 252, and this disclosure does not specifically limit the shape and length of the first wiring groove 1371.

[0195] To further improve the reliability of the heating wire 252's fixation, the wiring section 137 also includes a snap fastener (not shown). The snap fastener is located at the opening of the first wiring groove 1371, and the snap fastener and the first wiring groove 1371 together define a snap-fit ​​channel, in which the heating wire 252 is snapped into place. This prevents the heating wire 252 from coming out of the first wiring groove 1371, thus improving the reliability of the heating wire 252's fixation and facilitating assembly and disassembly.

[0196] In some embodiments, the wiring section 137 further includes a wire outlet hole 1372, which is located at one end of the first wiring groove 1371 away from the mounting platform 1381. The wire outlet hole 1372 extends through the heat exchanger bracket 131 along its thickness direction. It is understood that the heating wire 252 passes through the heat exchanger bracket 131 via the wire outlet hole 1372 to connect with the electrical control assembly 20. This further shortens the arrangement length of the heating wire 252, and the wire outlet hole 1372 can constrain the exit direction and position of the heating wire 252, thereby improving the secure installation of the heating wire 252.

[0197] To prevent air leakage or condensation from seeping into the outlet hole 1372, the inner side of the outlet hole 1372 can be abutted against the base 11 so that the base 11 blocks the inner side of the outlet hole 1372 without affecting the normal connection between the outlet hole 1372 and the first wiring groove 1371, that is, the heating wire 252 can pass through the outlet hole 1372 normally from the first wiring groove 1371.

[0198] In one example, the upper end of the outlet hole 1372 has a notch 13721, which communicates with the outlet hole 1372 and gradually widens from bottom to top. The heating wire 252 can be inserted into the outlet hole 1372 through the notch 13721, thereby facilitating the assembly of the heating wire 252. In addition, since the notch 13721 gradually widens from bottom to top, it can provide guidance for the insertion of the heating wire 252, further improving the assembly efficiency of the heating wire 252.

[0199] In some embodiments, the wiring section 137 further includes a wiring clip 1373, which is located on the side of the heat exchanger bracket 131 opposite to the heat exchanger 13. The wiring clip 1373 has a through hole 13731 through which the heating wire 252 passes. It is understood that the heating wire 252 passing through the outlet hole 1372 is fixed by the wiring clip 1373 before being extended into the electrical control assembly 20, in order to prevent the heating wire 252 from wobbling relative to the heat exchanger bracket 131.

[0200] Specifically, the cable routing clip 1373 and the cable outlet hole 1372 are arranged at intervals along the front-rear direction of the heat exchanger bracket 131. The heating wire 252 has a bent section 253, which is located between the cable outlet hole 1372 and the cable routing clip 1373. The bent section 253 has a U-shaped structure and protrudes towards the lower end of the heat exchanger bracket 131. It can be understood that, under the constraint of the cable outlet hole 1372 and the cable routing clip 1373, the bent section 253 of the heating wire 252 can be tightly attached to the outer wall of the heat exchanger bracket 131. Since the bent section 253 of the heating wire 252 is U-shaped and protrudes towards the lower end of the heat exchanger bracket 131, the condensate generated on the heat exchanger bracket 131 can be guided downward along the bent section 253 to improve the condensate drainage effect. On the other hand, since the heating wire 252 is configured as described above, condensate can be prevented from entering the electronic control assembly 20 along the extension direction of the heating wire 252, which helps to reduce the electrical safety hazards of the electronic control assembly 20.

[0201] In one example, the mounting platform 1381 is a cylindrical structure that protrudes away from the heater 251. The end of the cylindrical structure facing the heater 251 has a connector 13811, and the heater 251 has a connector that is installed within the connector 13811. It is understood that the end of the heater 251 (the connector) engages with the connector 13811 on the heat exchanger bracket 131 to facilitate the installation and removal of the heater 251.

[0202] In some embodiments, the fixing part 134 includes a plurality of spaced fixing sleeves 1344, the fixing sleeves 1344 protruding toward the side of the support body 133 away from the heat exchanger 13, the fixing sleeves 1344 being used to fix the metal tubes of the heat exchanger 13, the side of the heat exchanger support 131 away from the heat exchanger 13 being provided with a plurality of spaced support positions, the ends of the plurality of support positions being located in the same plane, the support position including a first support position 1391, and at least one fixing sleeve 1344 constituting the first support position 1391.

[0203] According to the embodiments of the present disclosure, the indoor unit of the air conditioner has a plurality of spaced support positions on the side of the heat exchanger bracket 131 away from the heat exchanger 13, and the ends of the plurality of support positions are located in the same plane. Thus, when the heat exchanger 13 is placed upright, the heat exchanger bracket 131 located at the end of the heat exchanger 13 can be supported by the plurality of support positions to ensure the stability of the heat exchanger 13 when it is upright, which is beneficial to the welding operation of the operator.

[0204] Understandably, having the ends of multiple support positions located in the same plane can improve the stability of the heat exchanger bracket 131 in contact with the ground. For example, there can be two, three, or more support positions.

[0205] Furthermore, since at least one fixing sleeve 1344 constitutes the first support position 1391, the fixing sleeve 1344 can both fix the metal tube of the heat exchanger 13 and provide auxiliary support for the upright position of the heat exchanger 13. This improves the integration level of the heat exchanger bracket 131 and saves the arrangement space on the heat exchanger bracket 131. It is understood that, compared with the solution of setting a separate support position, the heat exchanger bracket 131 of the embodiments of this disclosure can utilize the structure of the heat exchanger bracket 131 itself and does not occupy too much space on the heat exchanger bracket 131, thereby reducing the obstruction of condensate on the heat exchanger bracket 131, improving the condensate guiding effect on the heat exchanger bracket 131, and improving the integration level of the heat exchanger bracket 131.

[0206] For example, a single fixing sleeve 1344 can constitute the first support position 1391. Or, multiple fixing sleeves 1344 can be used together to constitute the first support position 1391.

[0207] In some embodiments, the support position includes a second support position 1392, and the heat exchanger bracket 131 further includes a bearing housing 1383. The bearing housing 1383 supports the end of the impeller 152, and protrudes from the side of the bracket body 133 away from the heat exchanger 13 to form the second support position 1392. It is understood that a bearing is installed inside the bearing housing 1383, and the end of the impeller 152 is rotatably supported within the bearing of the bearing housing 1383. The bearing housing 1383 serves both as a support for the impeller 152 and as an auxiliary support for the upright position of the heat exchanger 13. Therefore, the structure of the bearing housing 1383 of the heat exchanger bracket 131 can be utilized without excessively occupying space on the heat exchanger bracket 131, resulting in a simple structural design and ease of manufacturing for the heat exchanger bracket 131.

[0208] In some embodiments, at least one of the first baffle plate 13511 and the second baffle plate 13512 constitutes the third support position 1393.

[0209] In some embodiments, the support position includes a fourth support position 1394, and the heat exchanger bracket 131 further includes a protrusion 1382. The protrusion 1382 is disposed on the top of the bracket body 133 and arranged adjacent to the front side of the bracket body 133. The protrusion 1382 protrudes towards the side of the bracket body 133 away from the heat exchanger 13 to form the fourth support position 1394. By adding the fourth support position 1394, the heat exchanger bracket 131 of the embodiments of this disclosure can make the support effect of the heat exchanger bracket 131 more stable than the support effect of three-point support (first support position 1391, second support position 1392 and third support position 1393).

[0210] The indoor unit of an air conditioner according to another embodiment of the present disclosure is described below with reference to Figure 15.

[0211] The indoor unit of the air conditioner according to this embodiment includes: a base 11, a motor cover 19, a cross-flow fan 151, and a connector. The base 11 is used to install the heat exchanger 13. The motor cover 19 is located on one side of the base 11 along its length. The upper end of the motor cover 19 has a receiving cavity 1941. The cross-flow fan 151 includes a motor body 1511 and a first motor wire 1512. The motor body 1511 is located inside the motor cover 19 and connected to one end of the first motor wire 1512. The connector is connected in series with the first motor wire 1512 and is installed in the receiving cavity 1941.

[0212] According to the embodiments of the present disclosure, the indoor unit of the air conditioner has a receiving cavity 1941 provided at the upper end of the motor cover 19, and the connector is installed in the receiving cavity 1941. The position of the connector can be fixed. Since the connector is connected in series with the first motor wire 1512, when the operator needs to remove the cross-flow fan 151, the first motor wire 1512 can be disconnected from the position of the connector, so that it is not necessary to remove the entire first motor wire 1512. This simplifies the disassembly and assembly process for the operator and improves the convenience of the operator during maintenance.

[0213] For example, the connector includes a first pair of connectors connected in series with the first motor wire 1512. It should be noted that the first pair of connectors is a detachable connection structure between the wire tip and the terminal block. For example, the wire tip and terminal block of the first pair of connectors can be connected by plug-in, crimp, or threaded connection. It can be understood that the first motor wire 1512 is divided into two sections: one section connects to the motor body 1511 and the wire tip, and the other section connects to the terminal block and the electrical control assembly 20.

[0214] In the example of this disclosure, a portion of the first motor wire 1512 extends along the length of the base 11 and is arranged above the base 11. Since the accommodating cavity 1941 of the air conditioner indoor unit of this disclosure is located at the upper end of the motor cover 19, the wiring path of the first motor wire 1512 can first pass through the accommodating cavity 1941 and then be arranged above the base 11. This wiring method can shorten the wiring length of the first motor wire 1512 and make full use of the space above the motor cover 19 without increasing the length dimension of the air conditioner indoor unit, making the component arrangement of the air conditioner indoor unit more compact.

[0215] In some embodiments, the motor cover 19 includes a cover body 193 and a wiring housing 194. The wiring housing 194 is connected to the cover body 193 and is located at the upper end of the cover body 193. The wiring housing 194 has a receiving cavity 1941, and the cover body 193 has a motor cavity 1931. The motor body 1511 is located in the motor cavity 1931. It is understood that the cover body 193 and the wiring housing 194 are independent cavity structures to ensure that the motor body 1511 and the first connector do not interfere with each other during arrangement and to facilitate the management of the first motor wire 1512.

[0216] The wiring housing 194 opens to the side opposite to the base 11. That is, the front end face of the wiring housing 194 (the side facing the frame 10) is open. It can be understood that the front end of the wiring housing 194 has an open opening 1942 that communicates with the receiving cavity 1941. The front-rear direction of the wiring housing 194 is consistent with the front-rear direction of the base 11.

[0217] Because the front end of the wiring housing 194 is open, the operator can easily observe the position of the receiving cavity 1941. When the operator is wiring, the first pair of connectors (wiring devices) can be directly inserted into the receiving cavity 1941 through the open opening 1942. Similarly, when the operator is removing the motor, the first pair of connectors (wiring devices) can be removed from the receiving cavity 1941 through the open opening 1942.

[0218] The indoor unit of an air conditioner according to another embodiment of the present disclosure is described below with reference to Figure 15.

[0219] The top surface of the base 11 is provided with a wiring section 113, which is arranged along the length of the base 11 and is used to fix the wire harness.

[0220] In some embodiments, the wiring section 113 includes a wiring groove 1131 that extends along the length of the base 11 and opens upward toward the base 11. The wire harness can be arranged within the wiring groove 1131 to conceal it, thereby avoiding interference during the assembly of components of the indoor air conditioner unit and reducing the probability of damage to the wire harness due to collisions and friction. Furthermore, the upward-opening wiring groove 1131 facilitates the removal and placement of the wire harness by operators, improving the ease of assembly and disassembly.

[0221] Furthermore, the wiring section 113 also includes a plurality of wire clips 1132, which are spaced apart along the length of the wiring groove 1131, and the wire clips 1132 and the wiring groove 1131 together form a wire-holding cavity. It is understood that the wire clips 1132 can fix the wire harness within the wiring groove 1131 to prevent the wire harness from coming out of the wiring groove 1131, thus improving the reliability of the wire harness fixation.

[0222] The indoor unit of an air conditioner according to another embodiment of the present disclosure is described below with reference to Figure 16.

[0223] The indoor unit of the air conditioner according to this embodiment includes: a frame 10, a filter 28, a snap-fit ​​component, and a magnetic component. The frame 10 is provided with an air inlet 101 and an air outlet 102. The air inlet 101 is located at the lower end of the frame 10. The filter 28 is located outside the frame 10 and covers the position of the air inlet 101. The filter 28 is snapped to the frame 10 by the snap-fit ​​component and magnetically engaged with the frame 10 by the magnetic component. At least a portion of the snap-fit ​​component and at least a portion of the magnetic component are arranged in different directions of the filter 28.

[0224] According to the embodiments of the present disclosure, the air conditioner indoor unit uses a filter 28 that is snapped onto the frame 10 via a snap-fit ​​component and magnetically attracted to the frame 10 via a magnetic attraction component. At least a portion of the snap-fit ​​component and at least a portion of the magnetic attraction component are arranged in different directions on the filter 28. This provides double fixation for the filter 28, significantly reducing the probability of the filter 28 becoming detached from the frame 10 and lowering safety hazards. Furthermore, since the air inlet 101 is located at the lower end of the frame 10, compared to a solution where the air inlet 101 is located at the top of the frame 10, the distance between the air conditioner indoor unit and the ceiling wall of the room can be greatly reduced or eliminated, thereby improving the utilization rate of indoor space.

[0225] It should be noted that "at least a portion of the snap-fit ​​components" can refer to all the snap-fit ​​components or only a portion of them. Similarly, "at least a portion of the magnetic components" can refer to all the magnetic components or only a portion of them.

[0226] In some embodiments, snap-fit ​​components are arranged on both sides of the filter screen 28 in the width direction, and magnetic components are arranged on both sides of the filter screen 28 in the length direction. Thus, when the snap-fit ​​components fail, the magnetic components located on both sides of the filter screen 28 in the length direction can still firmly attach the filter screen 28 to the frame 10, thereby improving the stability of the filter screen 28.

[0227] The indoor unit of an air conditioner according to another embodiment of the present disclosure is described below with reference to Figures 17 and 18.

[0228] The indoor unit of the air conditioner according to this embodiment includes: a base 11, a decorative panel 31, and a wall-mounting panel 32. The back of the base 11 is provided with a wall-mounting hole 1141, which is arranged near the upper end of the base 11. The bottom of the base 11 is provided with a first support part 1142. The decorative panel 31 is detachably installed at the bottom of the base 11. The decorative panel 31 and the first support part 1142 together form a limiting cavity 1143. The upper end of the wall-mounting panel 32 is provided with a hook 323, and the lower end of the wall-mounting panel 32 is provided with a support hook 324. The hook 323 is hooked into the wall-mounting hole 1141, and the support hook 324 is located in the limiting cavity 1143 and supported on the bottom surface of the first support part 1142.

[0229] According to the embodiments of the present disclosure, when the operator installs the base 11 onto the wall mounting plate 32, the wall mounting hook 323 can be inserted into the wall mounting hole 1141 of the base 11, and the support hook 324 supports the bottom surface of the base 11 to fix the base 11. Since the decorative panel 31 is detachably installed at the bottom of the base 11, and the decorative panel 31 and the first support part 1142 together form a limiting cavity 1143, the operator can install the decorative panel 31 after the base 11 and the wall mounting plate 32 are installed, so as to limit the upward movement of the base 11 by the decorative panel 31. Thus, when the base 11 is subjected to an upward force, the decorative panel 31 can abut against the support hook 324, thereby avoiding the problem of the wall mounting hole 1141 and the hook 323 disengaging due to the upward movement of the base 11. Therefore, the air conditioner indoor unit of the embodiments of the present disclosure is beneficial to improving the reliability of the air conditioner indoor unit installation.

[0230] Understandably, the installation steps for the indoor unit of an air conditioner are as follows:

[0231] S1: Install the wall panel 32 to the designated position on the wall;

[0232] S2: Remove the decorative panel 31 from the base 11;

[0233] S3: Install the base 11 and hang it on the wall panel 32 in the direction from top to bottom. At this time, the hook 323 is inserted into the wall hole 1141 of the base 11, and the support hook 324 supports the bottom surface of the base 11.

[0234] S4: Install the decorative panel 31 onto the bottom surface of the base 11, and the decorative panel 31 and the first support part 1142 can form a limiting cavity 1143, at which time at least part of the support hook 324 is located in the limiting cavity 1143.

[0235] When the base 11 moves upward under the action of external force, since the decorative panel 31 is relatively fixed to the base 11 and the decorative panel 31 is located at the lower end of the support hook 324, the decorative panel 31 can constrain the upward movement of the base 11 to avoid the problem of the wall hanging hole 1141 and the hook 323 disengaging due to the upward movement of the base 11.

[0236] The upper surface of the decorative panel 31 may have a slight gap with the lower surface of the support hook 324, or it may be in close contact with the lower surface of the support hook 324. In the example of this disclosure, the upper surface of the decorative panel 31 abuts against the upper surface of the support hook 324. That is, the upper surface of the decorative panel 31 is in close contact with the upper surface of the support hook 324 to further reduce the possibility of the base 11 moving upward relative to the wall panel 32.

[0237] In some embodiments, the decorative panel 31 is snapped into the base 11, thereby improving the ease of assembling and disassembling the decorative panel 31.

[0238] The indoor unit of an air conditioner according to another embodiment of the present disclosure is described below with reference to Figures 19 and 20.

[0239] The inner wall of the frame 10 of the air conditioner indoor unit of the present disclosure is provided with a wire fixing part 108. The air conditioner indoor unit also includes an air guide assembly 33, which includes an air guide drive component 332 and an air guide plate 331. The air guide plate 331 is provided at the air outlet. The air guide drive component 332 is provided on the frame 10 and connected to the air guide plate 331. The air guide drive component 332 has a first wire harness 33324, which is installed in the wire fixing part 108.

[0240] Therefore, the first wiring harness 3324 of the air guide assembly 22 is fixed to the frame 10 by the wire fixing part 108. This not only constrains the position of the first wiring harness 3324, but also avoids the first wiring harness 3324 from contacting the wall of the heat exchanger 13, thereby reducing the probability of the first wiring harness 3324 coming into contact with condensate and reducing the safety hazards when the air conditioner indoor unit is working.

[0241] In some embodiments, the indoor unit of the air conditioner further includes a display module 34, which includes a display screen and a display box 342. The display screen is disposed on the front wall of the frame 10, and the display box 342 is disposed on the rear side of the display screen. At least a portion of the wire fixing portion 108 and the display box 342 define a wire fixing channel 343, which is used to fix the first wire harness 3324.

[0242] According to the embodiments of the present disclosure, since at least a portion of the wiring harness 108 and the display box 342 define a wiring channel 343, the first wiring harness 3324 can be fixed in the wiring channel 343. This not only constrains the position of the first wiring harness 3324, but also prevents the first wiring harness 3324 from contacting the wall of the heat exchanger 13, thereby reducing the probability of the first wiring harness 3324 coming into contact with condensate and reducing safety hazards when the air conditioner indoor unit is working.

[0243] On the other hand, the air conditioner indoor unit of the present disclosure can use the display box 342 itself to fix the first wiring harness 3324, thereby reducing the production cost of the air conditioner indoor unit, and the structure is simple and easy to process and manufacture.

[0244] In the example of this disclosure, the wiring channel 343 extends vertically along the frame 10. It is understood that the first wiring harness 3324 needs to be introduced into the control box from below, thus requiring the first wiring harness 3324 to extend a certain distance vertically along the frame 10 before being introduced into the control box. By extending the wiring channel 343 vertically along the frame 10, the indoor unit of the air conditioner in this embodiment of the disclosure improves the secure fixing of the first wiring harness 3324, further preventing the first wiring harness 3324 from coming into contact with condensate due to loosening.

[0245] In some embodiments, the wire securing portion 108 includes a first pressure plate 1081, and a first wire blocking block 3421 is provided on the display box 342. The first wire blocking block 3421 and the first pressure plate 1081 are spaced apart along the length direction of the frame 10 and define a first wire securing cavity, which communicates with the wire securing channel 343. It is understood that the first pressure plate 1081 and the first wire blocking block 3421 are arranged on the extension path of the wire securing channel 343. Because the first wire blocking block 3421 and the first pressure plate 1081 are spaced apart, it is convenient for an operator to pass through the gap between the first wire blocking block 3421 and the first pressure plate 1081 and press it into the first wire securing cavity. Furthermore, the first wire blocking block 3421 can stop the first wire bundle 3324, thereby reducing the probability of the first wire bundle 3324 detaching from the first wire securing cavity.

[0246] In some embodiments, the wire securing portion 108 further includes a second pressure plate 1082, which is spaced apart from the sidewall of the display box 342 along the length of the frame 10 and defines a second wire securing cavity, which communicates with the wire securing channel 343. It is understood that the second pressure plate 1082 is spaced apart from the sidewall of the display box 342 to form the second wire securing cavity. This further constrains the first wire harness 3324, thereby further improving the secure installation of the first wire harness 3324.

[0247] Specifically, the wiring harness 108 includes a first wiring clip 1084, which is arranged near the air outlet 102 and located below the air outlet 102. The first wire harness 3324 is snapped into the first wiring clip 1084. Since the first wiring clip 1084 is located below and near the air outlet 102, it can reduce the winding of the first wire harness 3324, shorten the arrangement path of the first wire harness 3324, and keep the first wire harness 3324 as far away as possible from the water collection tray at the bottom of the air conditioner indoor unit. This can reduce the probability of the first wire harness 3324 coming into contact with condensate and improve the electrical safety of the air conditioner indoor unit.

[0248] In one example, the first wire fastener 1084 has a fourth wire-fixing cavity, which opens upwards. It is understood that the upper end of the fourth wire-fixing cavity has an opening. Therefore, the first wire harness 3324 can be pressed downwards into the fourth wire-fixing cavity from the upper end of the first wire fastener 1084. On the one hand, this improves the ease of installation of the first wire harness 3324; on the other hand, because the opening of the fourth wire-fixing cavity faces upwards, the first wire harness 3324 is less likely to detach from the fourth wire-fixing cavity, thus improving the reliability of the installation of the first wire harness 3324.

[0249] In the example disclosed herein, the air guide drive component 332 includes a first motor module 3321, a second motor module 3322, and a rocker arm 3323. The first motor module 3321 is mounted on the frame 10 and connected to one end of the rocker arm 3323. The other end of the rocker arm 3323 is connected to the second motor module 3322. The second motor module 3322 is connected to the air guide plate 331. The first motor module 3321 drives the rocker arm 3323 to swing, thereby controlling the opening and closing of the air guide plate 331. The second motor module 3322 drives the air guide plate 331 to rotate, thereby controlling the tilt angle (air guide angle) of the air guide plate 331. The motor wires of the first motor module 3321 and the second motor module 3322 constitute a first wiring harness 3324. It is understood that the motor wires of the first motor module 3321 and the second motor module 3322 are both fixed by clamping wires using a first wire fastener 1084 and a second wire fastener.

[0250] The first motor module 3321 can be a "motor + reducer" structure or a single motor structure. Similarly, the second motor module 3322 can be a "motor + reducer" structure or a single motor structure. This disclosure does not limit the specific configuration.

[0251] Since the motor wires of the first motor module 3321 and the second motor module 3322 are fixed by wire clamping through the wire fixing channel 343, the motor wires (first wire harness 3324) can be prevented from contacting the first motor module 3321 and the second motor module 3322, thus preventing the vibration of the first motor module 3321 and the second motor module 3322 from being transmitted to the motor wires (first wire harness 3324) and causing abnormal noise.

[0252] The indoor unit of an air conditioner according to another embodiment of the present disclosure is described below with reference to Figure 21.

[0253] In some embodiments, the display module 34 includes a display box 342, a primary control board 344, and a humidity sensor 345. The primary control board 344 is installed inside the cavity of the display box 342, and the humidity sensor 345 is installed on the primary control board 344.

[0254] The humidity sensor 345 is disposed within the cavity formed by the display box 342 and mounted on the first electronic control board 344. Therefore, there is no need for wires to electrically connect the humidity sensor 345 and the first electronic control board 344, nor is there a mounting position for the humidity sensor 345 on the outside of the display box 342. This results in fewer parts in the display module 34, a simpler structure for the display box 342, and higher assembly efficiency for the humidity sensor 345.

[0255] It should be noted that the display module 34 is mounted on the frame, and the display module 34 integrates display components for displaying temperature and humidity externally.

[0256] In some embodiments, the display box 342 is mounted at one end of the frame along its length. The end of the display box 342 facing the frame along its length is provided with a detection hole 3422 that communicates with the mounting cavity. The detection hole 3422 extends along a first direction, and the detection hole 3422 and the humidity sensor 345 are arranged along the length of the frame.

[0257] By setting the detection hole 3422, air circulation can be ensured between the installation cavity and the air conditioner's internal cavity, and thus with the indoor air. This allows the humidity sensor 345 to detect indoor air humidity more accurately. Moreover, by placing the detection hole 3422 on the side of the display box 342 adjacent to the frame side panel, air circulation between the display box's internal air and outdoor air can be achieved more quickly, thereby further improving the humidity sensor 345's accuracy in detecting indoor air humidity.

[0258] The indoor unit of an air conditioner according to another embodiment of the present disclosure is described below with reference to Figure 22.

[0259] The indoor unit of the air conditioner in this embodiment of the present disclosure also includes a swing motor 171 and an electronic control assembly 20. The swing motor 171 has a second motor wire 1712. The electronic control assembly 20 includes an electronic control box 202 and an electronic control board 20245. The electronic control board 20245 is disposed inside the electronic control box 202. The electronic control box 202 is disposed on one side of the heat exchanger 13 along its length. The electronic control box 202 is provided with a first wiring portion 20251. The first wiring portion 20251 is disposed on the lower side of the air guide frame 14 and is arranged adjacent to the swing motor 171. The second motor wire 1712 passes through the first wiring portion 20251 and is connected to the electronic control board 20245.

[0260] Specifically, the air guide frame 14 and the heat exchanger 13 are both installed in the space enclosed by the frame 10 and the base 11. The air guide frame 14 is provided with an air guide channel 1415 and is connected to the air outlet 102. The air sweeping plate 174 is located in the air guide channel 1415.

[0261] According to the embodiments of the present disclosure, the air conditioner indoor unit, by placing the first wiring portion 20251 on the lower side of the air guide frame 14, ensures that the air guide frame 14 does not obstruct or interfere with the first wiring portion 20251 when the operator installs the guide frame onto the base 11. Furthermore, since the first wiring portion 20251 is arranged adjacent to the swing motor 171, the length of the second motor wire 1712 can be shortened, and it is convenient to introduce the second motor wire 1712 into the electrical control box 202 through the first wiring portion 20251. Therefore, the wiring method of the air conditioner indoor unit according to the embodiments of the present disclosure is simple, assembly is convenient, and it is beneficial to improve production efficiency.

[0262] Understandably, in the assembly process of the indoor unit of the air conditioner, the electrical control box 202 must be assembled before the air guide bracket 14. In related technologies, after the air guide bracket 14 is assembled, it will block the original inlet of the electrical control box 202, which will make it difficult to introduce the second motor wire 1712 of the swing motor 171 into the electrical control box 202 from the inlet, causing difficulties in wiring the indoor unit of the air conditioner.

[0263] The air conditioner indoor unit of the present disclosure arranges the first wiring part 20251 on the lower side of the air guide frame 14 and adjacent to the sweeping motor 171. This avoids affecting the wiring of the second motor wire 1712 due to the assembly of the air guide frame 14, and also avoids excessively extending the arrangement path of the second motor wire 1712. This reduces the cost of the second motor wire 1712 and helps to reduce electrical safety hazards.

[0264] In some embodiments, the electrical control assembly 20 further includes a grounding plate 20246 and a first grounding wire 20247. The grounding plate 20246 is disposed inside the electrical control box 202. The two ends of the first grounding wire 20247 are respectively connected to the heat exchanger 13 and the grounding plate 20246, and the first grounding wire 20247 passes through the first wiring portion 20251. It is understood that the heat exchanger 13 needs to be grounded to improve the electrical safety of the indoor unit of the air conditioner during operation. Since the first grounding wire 20247 also passes through the first wiring portion 20251, the structure of the first wiring portion 20251 can be fully utilized, and the wiring is convenient, which helps to reduce assembly time.

[0265] For example, as shown in Figure 22, the heat exchanger 13 is provided with a grounding part 1331 on the side adjacent to the electrical control box 202, and the grounding part 1331 is connected to the first grounding wire 20247.

[0266] In some embodiments, the air guide assembly 33 is an upward-discharge air guide assembly 33. As shown in Figures 23 to 25, the air guide assembly 33 includes a mounting frame, an air guide drive component 332, and an air guide plate 331. The air guide drive component 332 is connected to the mounting frame. The air guide drive component 332 is throttlely connected to the air guide plate 331 to drive the air guide plate 331 to move. The mounting frame may be formed by the frame 10.

[0267] As shown in Figure 26, the air guide plate 331 includes a first air guide surface 33111, a transition air guide surface 33117, and a second air guide surface 33114 arranged sequentially along the Y direction in its width direction diagram. At least a portion of the first air guide surface 33111 is arranged obliquely relative to the transition air guide surface 33117 in a direction away from the transition air guide surface 33117, and at least a portion of the second air guide surface 33114 is arranged obliquely relative to the transition air guide surface 33117 in a direction away from the transition air guide surface 33117.

[0268] When the air guide plate 331 is closed, the width direction of the air guide plate 331 is consistent with the vertical direction. At least a portion of the first air guide surface 33111 is arranged obliquely relative to the transition air guide surface 33117 along the direction away from the transition air guide surface 33117. This can be understood as: only a portion of the first air guide surface 33111 is arranged obliquely relative to the transition air guide surface 33117 along the direction away from the transition air guide surface 33117; or, the entire first air guide surface 33111 is arranged obliquely relative to the transition air guide surface 33117 along the direction away from the transition air guide surface 33117. At least a portion of the second air guide surface 33114 is arranged at an angle relative to the transition air guide surface 33117 along the direction away from the transition air guide surface 33117. This can be understood as: only a portion of the second air guide surface 33114 is arranged at an angle relative to the transition air guide surface 33117 along the direction away from the transition air guide surface 33117; or, the entire second air guide surface 33114 is arranged at an angle relative to the transition air guide surface 33117 along the direction away from the transition air guide surface 33117.

[0269] For example, the transition air guide surface 33117 is disposed on the side facing the thickness direction (Z direction in the figure) of the air guide plate body 3311, at least a portion of the first air guide surface 33111 is inclined relative to the transition air guide surface 33117 along the other side facing the thickness direction of the air guide plate body 33111, and at least a portion of the second air guide surface 33114 is inclined relative to the transition air guide surface 33117 along the other side facing the thickness direction of the air guide plate body 33111.

[0270] As shown in Figure 24, the air guide assembly 33 is located at the air outlet 102 of the indoor unit of the air conditioner. In the cooling mode, the air at the air outlet 102 flows to the first air guide surface 33111 under the guidance of the transition air guide surface 33117, and the airflow is mainly guided by the first air guide surface 33111. In the heating mode, the air at the air outlet 102 flows to the second air guide surface 33114 under the guidance of the transition air guide surface 33117, and the airflow is mainly guided by the second air guide surface 33114. By arranging at least a portion of the first air guide surface 33111 at an angle relative to the transition air guide surface 33117 in a direction away from the transition air guide surface 33117, the vortex formed by the airflow at the air guide plate 331 can be reduced, thereby reducing the risk of condensation problems in the indoor unit of the air conditioner; by arranging at least a portion of the second air guide surface 33114 at an angle relative to the transition air guide surface 33117 in a direction away from the transition air guide surface 33117, the landing speed of the airflow passing through the air guide plate 331 can be increased, thereby improving the heating effect of the indoor unit of the air conditioner.

[0271] In practical use, as shown in Figure 23, in heating mode, the air guide plate 331 is in the first position. The air guide plate 331 rotates until the second air guide surface 33114 is located in front of the first air guide surface 33111, and the front end of the air guide plate 331 is lower than its rear end. At this time, the airflow at the air outlet 102 is mainly guided by the second air guide surface 33114. As shown in Figure 24, in cooling mode, the air guide plate 331 is in the second position. The air guide plate 331 rotates until the first air guide surface 33111 is located in front of the second air guide surface 33114, and the front and rear ends of the air guide plate 331 are roughly at the same height. At this time, the airflow at the air outlet 102 is mainly guided by the first air guide surface 33111. During the operation of the indoor unit of the air conditioner, the air guide plate 331 can also be in other positions, such as the third position shown in Figure 24.

[0272] In some embodiments, as shown in FIG26, the transition air guide surface 33117 is an arc surface.

[0273] In some embodiments, as shown in FIG26, the first air guide surface 33111 includes a first portion 33112 and a second portion 33113. The first portion 33112 is disposed between the second portion 33113 and the transition air guide surface 33117 in the width direction of the air guide plate body 3311. The first portion 33112 is smoothly connected to the transition air guide surface 33117, and the second portion 33113 is arranged obliquely relative to the transition air guide surface 33117 in a direction away from the transition air guide surface 33117.

[0274] Understandably, the second part 33113 is arranged at an angle relative to the transition air guide surface 33117 along the direction away from the transition air guide surface 33117, in order to reduce the vortex formed by the airflow at the air guide plate 331 and reduce the risk of condensation problems in the indoor unit of the air conditioner.

[0275] In some embodiments, the included angle between the first portion 33112 and the second portion 33113 is 106° to 158°.

[0276] For example, as shown in Figure 26, the angle between the first part 33112 and the second part 33113 is α1, and α1 is 132°.

[0277] By setting the included angle between the first part 33112 and the second part 33113 to 106° to 158°, the eddy currents at the air guide plate 331 in the cooling mode can be effectively reduced, thereby reducing the risk of condensation problems in the indoor unit of the air conditioner.

[0278] In some embodiments, as shown in FIG26, the second air guide surface 33114 includes a third portion 33115 and a fourth portion 33116. The third portion 33115 is disposed between the fourth portion 33116 and the transition air guide surface 33117 in the width direction of the air guide plate body 3311. The third portion 33115 is smoothly connected to the transition air guide surface 33117, and the fourth portion 33116 is arranged obliquely relative to the transition air guide surface 33117 in a direction away from the transition air guide surface 33117.

[0279] Understandably, the fourth part 33116 is arranged at an angle relative to the transition air guide surface 33117 along the direction away from the transition air guide surface 33117, in order to increase the landing speed of the airflow passing through the air guide plate 331 and improve the heating effect of the air conditioner indoor unit.

[0280] In some embodiments, the third portion 33115 is a concave arc surface, and the radius of the third portion 33115 is 30mm to 45mm.

[0281] For example, as shown in Figure 26, the radius of the third part 33115 is R, and R is 37 mm.

[0282] By setting the radius of the third part 33115 to 30mm to 45mm, the landing speed of the airflow passing through the air guide plate 331 in the heating mode can be further improved, thereby improving the heating effect of the air conditioner indoor unit.

[0283] In some embodiments, the radius of the third part 33115 is 18° to 28°.

[0284] For example, as shown in Figure 26, the radian of the third part 33115 is β1, and β1 is 23°.

[0285] By setting the curvature of the third part 33115 to 18°~28°, the landing speed of the airflow passing through the air guide plate 331 in heating mode can be further improved, thereby enhancing the heating effect of the indoor unit of the air conditioner.

[0286] In some embodiments, the included angle between the first portion 33112 and the fourth portion 33116 is 42° to 62°.

[0287] For example, as shown in Figure 26, the angle between the first part 33112 and the fourth part 33116 is γ, and γ is 52°.

[0288] By setting the angle between the first part 33112 and the fourth part 33116 to 42° to 62°, the landing speed of the airflow passing through the air guide plate 331 in the heating mode can be further improved, thereby improving the heating effect of the air conditioner indoor unit.

[0289] As shown in Figure 26, the air guide plate 331 also includes a partition 3312 and an outer plate 3313. The air guide plate body 3311 is connected to the outer plate 3313 through the partition 3312.

[0290] In some embodiments, as shown in Figures 25, 27, and 28, the air guide drive component 332 includes a drive member 33211, a rocker arm 3323, and a limiting member 3325. The drive member 33211 is connected to the mounting bracket and is throttle-connected to the rocker arm 3323 to drive the rocker arm 3323 to rotate relative to the mounting bracket. The rocker arm 3323 has a rocker arm protrusion 33235 on one axial side of its rotation axis. The limiting member 3325 is located on the side of the rocker arm 3323 facing the rocker arm protrusion 33235 and is connected to the mounting bracket. The rocker arm protrusion 33235 and the limiting member 3325 are rotatably connected.

[0291] In actual use, the rocker arm 3323 is connected to the air guide plate 331 via a transmission.

[0292] When the air guide assembly 33 is working, the rocker arm 3323 is driven to rotate by the drive component 33211, and the rocker arm 3323 drives the air guide plate 331 to rotate to different air delivery angles. By providing a rocker arm protrusion 33235 on one side of the axial direction of the rocker arm 3323's shaft, and providing a limiting component 3325 on the side of the rocker arm 3323 facing the rocker arm protrusion 33235, the rocker arm protrusion 33235 and the limiting component 3325 are rotatably connected, so that when the rocker arm 3323 rotates, the limiting component 3325 can restrict the position of the rocker arm 3323 on the axial direction of the shaft, reducing the risk of the rocker arm 3323 wobbling, thereby improving the rotation accuracy of the air guide plate 331 and reducing the risk of abnormal noise from the rocker arm 3323.

[0293] In some embodiments, as shown in FIG28, the rocker arm protrusion 33235 is a plug shaft, the limiting member 3325 is provided with a first plug hole 33252, and the plug shaft is rotatably connected to the first plug hole 33252.

[0294] To make the technical solution of this disclosure easier to understand, the following description further illustrates the technical solution of this disclosure, taking the example that the axial direction of the rotating shaft is consistent with the left and right directions.

[0295] For example, as shown in Figures 27 and 28, a rocker arm protrusion 33235 is provided on the right side of the rocker arm 3323, a limiting member 3325 is provided on the right side of the rocker arm 3323, a first insertion hole 33252 extends in the left and right direction, and the rocker arm protrusion 33235 is inserted into the first insertion hole 33252 from left to right.

[0296] In some embodiments, as shown in FIG28, the limiting member 3325 includes a guide hole 33253, which is disposed on the side of the first insertion hole 33252 facing the rocker arm 3323 and communicates with the first insertion hole 33252. The diameter of the guide hole 33253 gradually increases in the direction away from the first insertion hole 33252.

[0297] For example, as shown in Figure 28, the rocker arm 3323 is located on the left side of the limiting member 3325, the guide hole 33253 is located on the left side of the first insertion hole 33252, and the diameter of the guide hole 33253 gradually increases from right to left.

[0298] By setting the guide hole 33253, the rocker arm protrusion 33235 can guide the rocker arm protrusion 33235 during the process of inserting into the guide hole 33253, making it easier for the rocker arm protrusion 33235 to be inserted into the guide hole 33253, thereby facilitating the assembly of the air guide drive component 332.

[0299] In some embodiments, as shown in FIG28, the rocker arm 3323 includes an extension 33232, which is disposed on the side of the rocker arm protrusion 33235 away from the limiting member 3325. At least a portion of the extension 33232 is disposed within the guide hole 33253, and the diameter of the extension 33232 gradually increases in the direction away from the first insertion hole 33252.

[0300] For example, the extension 33232 is located on the left side of the rocker arm protrusion 33235, and the diameter of the extension 33232 gradually increases from right to left. A portion of the extension 33232 is located inside the guide hole 33253, and another portion of the extension 33232 is located outside the guide hole 33253.

[0301] By providing an extension section 33232 to the rocker arm 3323, and having the diameter of the extension section 33232 gradually increase in the direction away from the first insertion hole 33252, the rigidity of the rocker arm 3323 can be improved, further reducing the risk of the rocker arm 3323 swaying, improving the rotation accuracy of the air guide plate 331, and reducing the risk of abnormal noise from the rocker arm 3323.

[0302] In some embodiments, as shown in FIG28, the rocker arm 3323 includes a rod body 33231 and a limiting rod 33233. The rod body 33231 is convexly connected to the drive member 33211. The limiting rod 33233 includes a first segment 33234 and a second segment, which are arranged axially along the rotation axis. The first segment 33234 is fixedly connected to the rod body 33231, and the second segment forms a rocker arm protrusion 33235.

[0303] For example, the rod body 33231 is located on the left side of the limiting rod 33233, the first segment 33234 is located on the left side of the second segment, the first segment 33234 is embedded in the rod body 33231, the second segment is located on the outside of the rod body 33231, and the second segment forms the rocker arm protrusion 33235.

[0304] By setting the rocker arm 3323 to the above structure, it is convenient to design and manufacture different parts of the rocker arm 3323 according to the requirements of different parts of the rocker arm 3323, so that the rocker arm 3323 can meet the rigidity requirements while keeping the cost of the rocker arm 3323 low.

[0305] In some embodiments, as shown in FIG28, the diameter of the first segment 33234 is larger than the diameter of the second segment.

[0306] By setting the diameter of the first segment 33234 to be larger than that of the second segment, not only can the connection area 1217 between the limiting rod 33233 and the rod body 33231 be increased, thereby improving the connection reliability between the limiting rod 33233 and the rod body 33231; but it can also prevent the limiting rod 33233 from falling off the limiting member 3325 in a direction away from the rod body 33231, thereby improving the reliability of the air guide drive component 332.

[0307] In some embodiments, the limiting rod 33233 is a metal rod.

[0308] By making the limiting rod 33233 a metal rod, the coefficient of friction between the limiting rod 33233 and the limiting member 3325 can be reduced, avoiding abnormal noise caused by friction between the rocker arm 3323 and the limiting member 3325 during the rotation of the rocker arm 3323, and further reducing the risk of abnormal noise during the rotation of the rocker arm 3323.

[0309] In some embodiments, as shown in FIG27, the limiting member 3325 is provided with a fourth fixing hole 33255, and the fastener passes through the fourth fixing hole 33255 and is connected to the mounting bracket. The fastener can be a bolt, screw, etc.

[0310] In some embodiments, as shown in FIG27, the limiting member 3325 includes a limiting body 33251 and a fixing ear 33254. The fixing ear 33254 is disposed on opposite sides of the limiting body 33251 in the radial direction of the rotating shaft and is connected to the limiting body 33251. The rocker arm protrusion 33235 is rotatably connected to the limiting body 33251, and the fixing ear 33254 is connected to the mounting bracket.

[0311] In some embodiments, the minimum dimension of the rocker arm 3323 in the axial direction of its pivot is 12mm to 24mm.

[0312] For example, as shown in Figure 27, the minimum dimension of the rocker arm 3323 in the axial direction of its rotating shaft is L3, which is 19.5 mm.

[0313] By setting the minimum dimension of the rocker arm 3323 in the axial direction of its rotating shaft to 12mm to 24mm, the thickness of the rocker arm 3323 is made larger, which can improve the rigidity of the rocker arm 3323, further reduce the risk of the rocker arm 3323 swaying, improve the rotation accuracy of the air guide plate 331, and reduce the risk of abnormal noise from the rocker arm 3323.

[0314] In some embodiments, as shown in Figures 25, 27, and 28, the air guide drive component 332 further includes a reduction gearbox 3326. The reduction gearbox 3326 includes a housing 33261 and an output shaft 33264. The housing 33261 is connected to a mounting bracket, and the drive component 33211 is connected to the rocker arm 3323 via the output shaft 33264. The drive component 33211 can be a motor, and multiple gears are disposed within the housing 33261.

[0315] By setting up the reduction gearbox 3326, the output torque of the drive component 33211 can be increased, the output torque of the rocker arm 3323 can be increased, and the rotational stability of the air guide plate 331 can be improved.

[0316] In some embodiments, as shown in Figures 25, 27 and 28, the gearbox 3326 and the limiting member 3325 are arranged on opposite sides of the rocker arm 3323 in the axial direction of the rotating shaft.

[0317] For example, the gearbox 3326 is located on the left side of the rocker arm 3323, and the limiting member 3325 is located on the right side of the rocker arm 3323. By using the gearbox 3326 and the limiting member 3325, the rocker arm 3323 can be stably limited in the left and right directions, further reducing the risk of the rocker arm 3323 shaking, further improving the rotation accuracy of the air guide plate 331, and reducing the risk of abnormal noise from the rocker arm 3323.

[0318] As shown in Figure 27, the gearbox 3326 is axially positioned on one side of the rocker arm 3323. The gearbox 3326 is provided with a gear protrusion 33265 on the side away from the rocker arm 3323. The gear protrusion 33265 is rotatably connected to the frame 10.

[0319] To make the embodiments of this disclosure easier to understand, the technical solution of this disclosure will be further described below using the example of the axial direction of the pivot of a rocker arm 3323 being consistent with the left-right direction. The left-right direction is shown in Figures 23, 24, and 27.

[0320] For example, as shown in Figures 24 and 27, the gearbox 3326 is located on the left side of the rocker arm 3323, and the gearbox 3326 has a gear protrusion 33265 on the left side, which is rotatably connected to the frame 10.

[0321] By providing a gear protrusion 33265 on the side of the gearbox 3326 away from the rocker arm 3323, and rotatably connecting the gear protrusion 33265 to the frame 10, when the gear inside the gearbox 3326 rotates, the frame 10 can be used to limit the axial position of the air guide drive component 332 on the rotating shaft, reducing the risk of the air guide drive component 332 shaking, thereby improving the rotation accuracy of the air guide plate 331 and reducing the risk of abnormal noise from the rocker arm 3323.

[0322] In some embodiments, the gear protrusion 33265 is a limiting post, and the frame 10 is provided with a limiting hole, with the limiting post and the limiting hole being rotatably connected.

[0323] By setting the gear protrusion 33265 as a limiting post and the frame 10 as a limiting hole, the limiting post and the limiting hole are rotatably connected, which facilitates the rotatable connection between the gear protrusion 33265 and the frame 10, thereby facilitating the installation and fixing of the air guide drive component 332.

[0324] In some embodiments, the gear protrusion 33265 is arranged coaxially with the output shaft 33264.

[0325] In some embodiments, the gearbox 3326 is detachably connected to the frame 10.

[0326] For example, as shown in Figure 27, the housing 33261 is provided with a connecting ear 33262, and the connecting ear 33262 is provided with a fourth connecting hole 33263. Fasteners pass through the connecting hole and are connected to the frame 10 to realize the connection and fixation between the housing 33261 and the frame 10. The fastener can be a bolt, screw, etc.

[0327] By detachably connecting the gearbox 3326 to the frame 10, it is convenient to replace and repair the gearbox 3326.

[0328] As shown in Figure 24, the air guide assembly 33 also includes a rotating rod 3314. One end of the rotating rod 3314 is connected to the air guide plate 331, and the other end of the rotating rod 3314 is rotatably connected to the rocker arm 3323.

[0329] For example, one end of the rotating rod 3314 is integrally formed with the air guide plate body 3311. As shown in Figures 27 and 28, the rocker arm 3323 is provided with a connecting part 33236, which is rotatably connected to the rotating rod 3314.

[0330] In some embodiments, as shown in FIG25, the frame 10 is provided with an air outlet 102, and the air guide plate 331 is provided corresponding to the air outlet 102 to close and open the air outlet 102. As shown in FIG24, the air guide assembly 33 of the air conditioner indoor unit also includes an air guide frame 14, which has a gap with the frame 10, and the air guide drive component 332 is disposed between the air guide frame 14 and the frame 10.

[0331] This allows the space between the air guide frame 14 and the frame 10 to also allow the air guide drive component 332 to move, thereby increasing the range of motion of the air guide drive component 332. This results in a larger opening angle of the air outlet 102 during the movement of the air guide plate 331, making it easier to achieve large-angle air delivery.

[0332] As shown in Figures 23 and 24, the frame 10 is also provided with an air inlet 101, which is located at the lower part of the frame 10. The indoor unit of the air conditioner also includes a heat exchanger 13, which is located inside the frame 10.

[0333] In actual use, indoor air enters the interior of the frame 10 from the air inlet 101 on the lower side of the air conditioner indoor unit, passes through the heat exchanger 13 and exchanges heat with the heat exchanger 13, and then flows out from the air outlet 102 on the upper side of the air conditioner indoor unit and blows into the room.

[0334] In some embodiments, as shown in FIG23, the frame 10 includes a front side panel 109, an air outlet 102 is disposed on the front side panel 109, and the front side panel 109 is arranged to gradually tilt backward in a direction from top to bottom.

[0335] By arranging the front panel 109 to gradually tilt backward from top to bottom, airflow can also pass through the lower side of the air outlet 102 in heating mode, thereby making the airflow entering through the air inlet 101 at a higher temperature, realizing the internal circulation of hot airflow, which can perform high-temperature sterilization on the heat exchanger 13 and prevent odors from appearing in the air conditioner indoor unit.

[0336] In some embodiments, as shown in FIG23, the tilt angle of the front side panel 109 is 6° to 14°.

[0337] For example, the tilt angle of the front side panel 109 is θ, where θ is 10°.

[0338] Understandably, the larger the tilt angle of the front panel 109, the more hot air enters through the air inlet 101, and the better the high-temperature sterilization effect of the heat exchanger 13. However, there is less hot air in the room, which is not conducive to improving the heating effect of the air conditioner indoor unit. On the other hand, the smaller the tilt angle of the front panel 109, the less hot air enters through the air inlet 101, and the more hot air in the room, which is conducive to improving the heating effect of the air conditioner indoor unit. However, the effect of high-temperature sterilization by the heat exchanger 13 is worse.

[0339] By setting the tilt angle of the front side panel 109 to 6° to 14°, the high-temperature sterilization effect of the heat exchanger 13 can be guaranteed without affecting the indoor heating effect.

[0340] In some embodiments, as shown in Figures 29 to 30, the air duct 12 is an upward air outlet air duct 12, and the wall surface of the air duct 12 is provided with a protrusion 124.

[0341] For example, the air duct 12 includes an air duct housing 123 and a protrusion 124. The air duct housing 123 has an air duct body 1231 extending in the front-rear direction and an air duct outlet 1234 communicating with the air duct body 1231. The air duct outlet 1234 is located on the front side of the air duct body 1231 and communicates with the air outlet 102. The protrusion 124 is located at the air duct outlet 1234 and is connected to the air duct housing 123. The vertical direction is shown in Figures 29 and 30, and the front-rear direction is shown in Figure 30.

[0342] The indoor unit of the air conditioner in this embodiment of the present disclosure provides a protrusion 124 at the air outlet 1234 of the air duct body 1231, which can reduce the interception area of ​​the air outlet 1234, thereby improving the problem of insufficient airflow at the air outlet 1234, reducing the risk of airflow backflow at the air outlet 1234, and thus reducing the noise generated by the air duct 12, that is, reducing the noise of the indoor unit of the air conditioner with the air duct body 1231 during operation.

[0343] In some embodiments, as shown in Figures 29 and 30, the protrusion 124 is provided on the upper part of the air duct body 1231.

[0344] Experimental studies have shown that the upper part of the air outlet 1234 of the air duct body 1231 is most prone to insufficient airflow, which can easily cause noise due to airflow backflow.

[0345] By placing the protrusion 124 on the upper part of the air duct body 1231, the problem of insufficient airflow at the air duct outlet 1234 can be more effectively improved, thereby more effectively reducing the noise of the air duct 12.

[0346] In some embodiments, as shown in FIG29, the protrusions 124 are provided on both sides of the air duct body 1231 in the left-right direction.

[0347] Experimental studies have shown that the left and right sides of the duct body 1231 are most prone to insufficient airflow, which can easily cause noise due to airflow backflow.

[0348] By arranging the protrusions 124 on both sides of the air duct body 1231 in the left-right direction, the problem of insufficient airflow at the air duct outlet 1234 can be more effectively improved, thereby more effectively reducing the noise of the air duct 12.

[0349] In some embodiments, as shown in FIG29, the protrusions 124 on both sides of the air duct body 1231 are arranged symmetrically in the left-right direction.

[0350] In some embodiments, as shown in FIG30, the protrusion 124 has a first end portion 1214 and a second end portion 1216 arranged opposite to each other in the front-rear direction, with the first end portion 1214 located on the front side of the second end portion 1216. The distance between the first end portion 1214 and the air duct outlet 1234 is n, and the distance between the second end portion 1216 and the air duct outlet 1234 is m, where m > n, 0 ≤ n ≤ 70 mm, and 10 mm ≤ m ≤ 120 mm.

[0351] For example, as shown in Figure 30, the front opening of the air duct body 1231 is the air duct outlet 1234. The front end of the protrusion 124 is the first end 1214, and the distance between the front end of the protrusion 124 and the air duct outlet 1234 is greater than or equal to 0 and less than or equal to 70 mm; the rear end of the protrusion 124 is the second end 1216, and the distance between the rear end of the protrusion 124 and the air duct outlet 1234 is greater than or equal to 10 mm and less than or equal to 120 mm.

[0352] By making the distance between the first end 1214 and the air duct outlet 1234 greater than or equal to 0 and less than or equal to 70 mm, and the distance between the second end 1216 and the air duct outlet 1234 greater than or equal to 10 mm and less than or equal to 120 mm, the problem of insufficient airflow at the air duct outlet 1234 can be effectively improved, thereby more effectively reducing the noise generated by the air duct 12.

[0353] In some embodiments, the height of the protrusion 124 is greater than or equal to 2 mm and less than or equal to 30 mm. In other words, as shown in FIG30, the height of the protrusion 124 is t, where 2 mm ≤ t ≤ 30 mm.

[0354] It is understandable that the greater the height of the protrusion 124, the smaller the flow area of ​​the duct outlet 1234, which has a greater impact on the air volume of the duct outlet 1234 and is not conducive to improving the air volume of the duct 12; the smaller the height of the protrusion 124, the larger the flow area of ​​the duct outlet 1234, which is not conducive to improving the problem of insufficient airflow at the duct outlet 1234 and will still generate noise due to airflow backflow.

[0355] By setting the height of the protrusion 124 to be greater than or equal to 2mm and less than or equal to 30mm, the flow area of ​​the air duct outlet 1234 is not reduced too much. While improving the problem of insufficient airflow at the air duct outlet 1234, the air volume at the air duct outlet 1234 can also be guaranteed. Thus, the air conditioner indoor unit with this air duct 12 has low noise and a large air volume.

[0356] In some embodiments, as shown in FIG30, the duct housing 123 includes a mounting wall 1235, and a protrusion 124 is connected to the mounting wall 1235. The protrusion 124 has a first surface 1213 and a second surface 1215 arranged opposite to each other in a front-rear direction, the first surface 1213 being disposed on the front side of the second surface 1215. The first surface 1213 is gradually inclined away from the mounting wall 1235 in a front-to-back direction, and / or the second surface 1215 is gradually inclined towards the mounting wall 1235 in a front-to-back direction.

[0357] In some embodiments, the included angle between the second surface 1215 and the mounting wall 1235 is greater than 0° and less than 70°. In other words, the included angle between the second surface 1215 and the mounting wall 1235 is α2, where 0° < α2 < 70°.

[0358] By setting the angle between the second surface 1215 and the mounting wall 1235 to be greater than 0° and less than 70°, the flow resistance of the air outlet can be effectively reduced, the air volume loss of the air duct 12 can be reduced, and the air outlet volume of the air duct 12 can be increased.

[0359] In some embodiments, as shown in FIG30, the protrusion 124 further includes a connecting surface 1217 disposed toward the duct body 1231, the connecting surface 1217 being disposed between the first surface 1213 and the second surface 1215. The connecting surface 1217 is arranged at an angle gradually away from the mounting wall 1235 in a front-to-back direction.

[0360] In some embodiments, the included angle between the connecting surface 1217 and the mounting wall 1235 is greater than or equal to 0° and less than 40°. In other words, as shown in FIG30, the included angle β2 between the connecting surface 1217 and the mounting wall 1235 is 0°≤β2<40°.

[0361] By setting the angle between the connecting surface 1217 and the mounting wall 1235 to be greater than or equal to 0° and less than 40°, the flow resistance of the air outlet can be effectively reduced, the air volume loss of the air duct 12 can be reduced, and the air outlet volume of the air duct 12 can be increased.

[0362] In some embodiments, as shown in FIG30, the protrusion 124 is a hollow structure.

[0363] In some embodiments, as shown in Figures 31 and 32, the air guide frame 14 is provided with a recess 144 and an inlet / outlet 1441 communicating with the recess 144. The recess 144 is located on at least one side of the air guide frame 14 in the left-right direction, and the inlet / outlet 1441 is arranged facing forward. The recess 144 is used to accommodate the output member 3327 of the drive mechanism 18, and the inlet / outlet 1441 allows the output member 3327 to pass through the recess 144. The left-right direction is shown in Figure 31, and the front-back direction is shown in Figures 31 and 32.

[0364] When the air guide bracket 14 is used in an indoor air conditioner unit, the recess 144 of the air guide bracket 14 can accommodate the output component 3327 of the drive mechanism 18, and the output component 3327 can enter and exit the recess 144 in the front-to-back direction through the inlet and outlet 1441, so as to drive the air guide plate 331 of the indoor air conditioner unit to rotate or move. Thus, sufficient space is reserved inside the indoor air conditioner unit to accommodate the output component 3327.

[0365] Among them, the output component 3327 can be the rocker arm 3323.

[0366] In some embodiments, as shown in FIG27, the recess 144 includes a first receiving portion 1442 and a second receiving portion 1443. The first receiving portion 1442 extends in a vertical direction to receive a fifth portion 33271 of the output member 3327. The second receiving portion 1443 extends in a horizontal direction to receive a sixth portion 33272 of the output member 3327. The vertical direction is shown in FIGS. 31 and 32.

[0367] By configuring the recess 144 to include a first receiving portion 1442 and a second receiving portion 1443, with the first receiving portion 1442 extending vertically and the second receiving portion 1443 extending horizontally, the first receiving portion 1442 and the second receiving portion 1443 respectively accommodate the fifth portion 33271 and the sixth portion 33272 of the output component 3327. The first receiving portion 1442 and the second receiving portion 1443 can be designed according to the shape and size of the fifth portion 33271 and the sixth portion 33272, so that with a relatively small overall size of the recess 144, there is sufficient space to accommodate the output component 3327, thereby improving the structural strength of the air guide frame 14.

[0368] In some embodiments, as shown in FIG31, the air guide frame 14 has recesses 144 on both the left and right sides.

[0369] By providing recesses 144 on both the left and right sides of the air guide frame 14, output components 3327 located on the left and right sides of the air guide frame 14 can be accommodated respectively.

[0370] In some embodiments, as shown in FIG31, the recesses 144 provided on both sides of the air guide frame 14 are symmetrically arranged in the left-right direction.

[0371] By symmetrically arranging the recesses 144 on both sides of the air guide frame 14 in the left-right direction, the processing and manufacturing of the air guide frame 14 is facilitated, which helps to reduce the cost of the air guide frame 14.

[0372] In some embodiments, the minimum dimension of the recess 144 in the front-rear direction is 16mm to 26mm. In other words, the minimum depth of the recess 144 is 16mm to 26mm.

[0373] The maximum dimension of the recess 144 in the front-to-back direction is 52mm to 78mm. In other words, the maximum depth of the recess 144 is 16mm to 26mm.

[0374] For example, as shown in Figure 32, the minimum dimension of the recess 144 in the front-back direction is L4, which is 21 mm, and the maximum dimension of the recess 144 in the front-back direction is L5, which is 66 mm.

[0375] By setting the minimum size of the recess 144 in the front-to-back direction to 16mm to 26mm and the maximum size of the recess 144 in the front-to-back direction to 52mm to 78mm, the output component 3327 can be completely accommodated by the recess 144 while keeping the overall size of the recess 144 small, thus improving the structural strength of the air guide frame 14.

[0376] In some embodiments, as shown in FIG27, the output member 3327 is movable between a first position and a second position. In the first position, the output member 3327 extends at least partially beyond the recess 144. As shown in FIG32, in the second position, the output member 3327 retracts at least partially into the recess 144.

[0377] It should be noted that the first position and the second position are only two extreme positions of the output component 3327. During the operation of the air guide assembly 33, the output component 3327 is not limited to only the first position and the second position, but can also move to any position between the first position and the second position.

[0378] In some embodiments, in the second position, the minimum distance between the output member 3327 and the cavity wall of the recess 144 is greater than or equal to 3 mm.

[0379] For example, at the position shown in Figure 32, the minimum distance between the output component 3327 and the rear cavity wall of the recess 144 is L6, which is greater than or equal to 3 mm.

[0380] In other words, after the output component 3327 retracts into the recess 144, there is no contact between the output component 3327 and the cavity wall of the recess 144. As a result, the recess 144 can not only provide sufficient space for the output component 3327, but also avoids interference between the cavity wall of the recess 144 and the output component 3327, thereby improving the reliability of the air guide assembly 33.

[0381] In some embodiments, as shown in FIG33, the base 11 includes a base body 1150 and a base extension 116. The base extension 116 is disposed at one end of the base body 1150 in a second direction. A cross-flow fan 151 is mounted on the base body 1150. The cross-flow fan 151 and the base extension 116 are located at the same end of the base body 1150 in the second direction. The cross-flow fan 151 and the base extension 116 are spaced apart in a first direction. The cross-flow fan 151 includes a cover 1514. The cover 1514, the base extension 116, and one end face of the base body 1150 in a third direction jointly support the base body 1150 when the base body 1150 is erected in the third direction.

[0382] A seat extension 116 is formed by extending the seat body 1150 along one side of the second direction, and the seat extension 116 and the cover 1514 of the cross-flow fan 151 mounted on the seat body 1150 are spaced apart in the first direction. At this time, the seat extension 116, the cover 1514 and the seat body 1150 can simultaneously abut against the workbench surface in the third direction to achieve stable support for the base 11 erected along the third direction, thereby ensuring that the seat notch 1153 on the seat body 1150 is exposed, which effectively improves the installation efficiency of the evaporator on the seat body 1150.

[0383] Specifically, the seat extension 116 is located in front of the seat body 1150, and the seat extension 116 and the cover 1514 of the cross-flow fan 151 are respectively adjacent to the two ends of the seat body 1150 in the left and right directions.

[0384] In some embodiments, the end face of the base 1150 in the third direction includes a first end face 1151 and a second end face, and the cover 1514, the base extension 116 and the second end face together support the base 1150 when the base 11 is erected in the third direction.

[0385] At this point, the heat exchanger 13 can be moved from top to bottom to insert the copper tube on the heat exchanger 13 into the notch 1153 of the base body from top to bottom, thus completing the tube insertion operation. Then, the heat exchanger 13 is moved to the set position on the base body 1150, and the heat exchanger 13 and the base body 1150 are connected by fasteners, thus realizing the installation of the heat exchanger 13 on the base body 1150. The installation efficiency of the heat exchanger 13 is high.

[0386] Specifically, as shown in Figure 33, the first end face 1151 is the lower end face of the base 1150, and the base extension 116 and the cover 1514 of the cross-flow fan 151 are disposed on the upper end face of the base 1150. That is, when installing the heat exchanger 13, the base 1150 is placed upside down on the workbench. The base extension 116 has a third end face 1161 in the third direction, and the cover 1514 has a fourth end face 15141 in the third direction. The third end face 1161, the fourth end face 15141, and the second end face are coplanar.

[0387] In some embodiments, as shown in Figures 33-35, the heat exchanger 13 further includes a second bracket 1396. Both the heat exchanger bracket 131 and the second bracket 1396 are snapped into the base 1150. The heat exchanger bracket 131 is also connected to the base 1150 by fasteners. The base 1150 has a first support portion 117 and a bracket snap-fit ​​portion 119 at its first and second ends along the second direction, respectively. At least a portion of the heat exchanger bracket 131 is pressed against the first support portion 117 and the bracket snap-fit ​​portion 119 along the second direction.

[0388] The first end of the base 1150 along the second direction is also provided with a second support part 118, which abuts against the side of the second bracket 1396 along the second direction. Since the second bracket 1396 is only engaged with the right end of the base 1150, the connection strength between the right end of the heat exchanger 13 and the base 1150 is lower than the connection strength between the left end of the heat exchanger 13 and the base 1150. By setting the second support part 118 to abut against the rear side of the second bracket 1396, the right end of the heat exchanger 13 is supported in the front-rear direction, which can better prevent the heat exchanger 13 from shaking or deforming when subjected to external forces, and the installation reliability of the heat exchanger 13 on the base 1150 is high.

[0389] Specifically, the second support portion 118 forms a third support surface 1181 parallel to the rear side of the heat exchanger 13. The second bracket 1396 includes a third flange 13962 protruding from the side of the first heat exchange portion 1397 away from the second heat exchange portion 1398, and the third flange 13962 abuts against the third support surface 1181. The base 11 is engaged with the second bracket 1396 by a cross-flow fan 151.

[0390] In some embodiments, as shown in Figures 36 and 37, the indoor unit of the air conditioner further includes a bottom support 35, which includes a first reinforcing member 351 and a second reinforcing member 352. The base 11 includes a main body portion 1024 and a cantilever 1023 spaced apart along a first direction. A seat notch 1153 for a pipe to pass through is defined between the main body portion 1024 and the cantilever 1023. The first reinforcing member 351 is capable of connecting the main body portion 1024 and the cantilever 1023. The second reinforcing member 352 is connected to the first reinforcing member 351 and extends along a second direction. The second reinforcing member 352 is adapted to abut against the side of the cantilever 1023 opposite to the first direction.

[0391] The first reinforcing member 351 connects the main body 1024 of the base 11 and the cantilever 1023. The second reinforcing member 352, connected to the first reinforcing member 351, extends along the second direction and abuts against the side of the cantilever 1023 opposite to the first direction. The main body 1024, through the first reinforcing member 351 and the second reinforcing member 352, jointly supports the cantilever 1023 in the first direction. The bottom support member 35, through the second reinforcing member 352, further increases the contact area with the cantilever 1023. When the base 11 falls and the cantilever 1023 is impacted by the ground, the bottom support member 35 provides a wider support surface for the cantilever 1023 in the first direction, resulting in higher support stability and making the cantilever 1023 less prone to breakage due to greater impact force. Furthermore, at this time, the projected area of ​​the first reinforcing member 351 along the first direction and the projected area along the second direction can both be set to be smaller, the first reinforcing member 351 is less affected by the pipeline when connected to the cantilever 1023 and the main body 1024, and the first reinforcing member 351 is convenient and quick to install on the base 11.

[0392] It should be noted that both the cantilever 1023 and the main body 1024 are the base plates of the base 11 closest to the ground. The dimension of the cantilever 1023 in the first direction is much smaller than that of the main body 1024 in the first direction. When the base 11 falls to the ground, the cantilever 1023 is prone to excessive bending and damage in the first direction due to the impact from the ground. The sum of the dimensions of the first reinforcing member 351 and the second reinforcing member 352 in the second direction is slightly less than or equal to the dimension of the cantilever 1023 in the second direction, thereby effectively ensuring the support stability of the cantilever 1023.

[0393] In some embodiments, as shown in FIG37, the first reinforcing member 351 includes a first connecting portion 3511, a reinforcing portion 3512, and a second connecting portion 3513 connected in sequence. The first connecting portion 3511 is connected to the cantilever 1023, the second connecting portion 3513 is connected to the main body portion 1024, the reinforcing portion 3512 is connected to the second reinforcing member 352, and the second reinforcing member 352 is located in the seat notch 1153 and is connected to the side of the cantilever 1023 facing the main body portion 1024.

[0394] When the base 11 falls accidentally, the side of the cantilever 1023 facing away from the main body 1024 is more likely to collide with the ground first, making it more prone to bending and breaking towards the main body 1024. At this point, by placing the second reinforcing member 352 against the side of the cantilever 1023 facing the main body 1024, the second reinforcing member 352 better supports the cantilever 1023 in the first direction, making the cantilever 1023 less susceptible to impact breakage. Simultaneously, the second reinforcing member 352 is concealed within the seat body notch 1153, effectively ensuring the aesthetic appearance of the base 11.

[0395] In some embodiments, as shown in FIG33, the indoor unit of the air conditioner further includes a pipe pressure plate 36, which is connected to the base 11 and surrounds it to form a pipe channel. The pipe pressure plate 36 is located above the bottom support 35 and spaced apart from the bottom support 35.

[0396] The pipe clamp 36 can restrain the connecting pipes, preventing them from occupying too much space in the indoor unit of the air conditioner and affecting the operational reliability of other components. In addition, the pipe clamp 36 does not need to completely seal the opening of the through groove on the base 11; it only needs to achieve the restraining effect on the connecting pipes. As a result, the force that the pipe clamp 36 needs to overcome when it is connected to the base 11 is smaller, and the installation difficulty of the pipe clamp 36 on the base 11 is lower.

[0397] Specifically, the pipe pressure plate 36 is connected to the base 11 via at least two threaded fittings.

[0398] In some embodiments, as shown in Figures 38 and 39, a wall-mounted vertical plate 321 is connected to the second end of the base 11 in the second direction. An isolation cavity 10262 is defined between the wall-mounted vertical plate 321 and the base 11. A first water-guiding rib 1027 is provided on the surface of the second end of the base 11 in the second direction. The extension direction of the first water-guiding rib 1027 forms an acute angle with the first direction. A portion of the first water-guiding rib 1027 is located inside the isolation cavity 10262, and the lower end of the first water-guiding rib 1027 is located outside the isolation cavity 10262.

[0399] By providing a first water-guiding rib 1027 extending at an acute angle to the first direction on the back of the base 11, with a portion of the first water-guiding rib 1027 located within the isolation cavity 10262 formed between the wall-mounted vertical plate 321 and the base 11, and the lower end of the first water-guiding rib 1027 located outside the isolation cavity 10262, when the condensate in the isolation cavity 10262 flows downward along the back of the base 11 under gravity, it is blocked by the first water-guiding rib 1027 and flows out to the outside of the isolation cavity 10262 under the guidance of the first water-guiding rib 1027. This effectively prevents the condensate from continuing to flow downward within the isolation cavity 10262. At this time, the width of the portion of the isolation cavity 10262 located below the first water-guiding rib 1027 can be designed to be smaller to meet size requirements, and prevents the condensate from contacting the wall-mounted vertical plate 321 and causing dripping, thus improving the user experience.

[0400] In some embodiments, as shown in FIG38, the upper part of the first water guide bar 1027 is located outside the isolation cavity 10262.

[0401] Therefore, the first water guide rib 1027 spans the wall-mounted vertical plate 321. When the condensate in the isolation cavity 10262 located above the first water guide rib 1027 flows down the back of the base 11, it will be almost completely blocked by the first water guide rib 1027. The probability of condensate entering the isolation cavity 10262 located below the first water guide rib 1027 is even lower, which in turn reduces the probability of dripping and improves the user experience.

[0402] Specifically, on the projection plane perpendicular to the height direction, the projection dimension of the first water guide rib 1027 in the first direction is larger than the width of the wall-mounted vertical panel 321. The angle between the extension direction of the first water guide rib 1027 and the first direction is α, where 10°≤α≤45°.

[0403] As shown in Figures 41 and 42, the base 11 is provided with a bearing seat mounting groove 1034 at the first end in the second direction. The inner wall of the bearing seat mounting groove 1034 is provided with a first drain hole 1035 that runs through the base 11 in the second direction. The first drain hole 1035 is used to guide the condensate in the bearing seat mounting groove 1034 to the second end of the base 11 in the second direction.

[0404] When condensate generated on the bearing housing installed in the bearing housing mounting groove 1034 slides into the bearing housing mounting groove 1034, the condensate can be guided to the first drain hole 1035, and then guided from the first drain hole 1035 to the second end of the base 11 in the second direction, and finally guided from the surface along the second end of the base 11 in the second direction to the water receiving tray 26, effectively preventing the condensate in the bearing housing mounting groove 1034 from overflowing directly and causing the air conditioner to drip water, resulting in a good user experience.

[0405] It should be noted that a snap-fit ​​element is provided in the bearing housing mounting groove 1034, and at least a portion of the bearing housing extends into the bearing housing mounting groove 1034 and snaps into the snap-fit ​​element.

[0406] In some embodiments, as shown in FIG42, a water-blocking rib 10341 is provided on the inner wall surface of the bearing housing mounting groove 1034 opposite to the end face of the bearing housing. The water-blocking rib 10341 is located on the side of the bearing housing facing the first drain hole 1035 in the height direction. The extension direction of the water-blocking rib 10341 is at an angle to the height direction. The end of the water-blocking rib 10341 away from the bearing housing in the height direction is connected to the first drain hole 1035.

[0407] After at least a portion of the bearing housing is engaged with the snap-fit ​​element in the bearing housing mounting groove 1034, the bearing housing, the water-blocking rib 10341, and the inner wall of the bearing housing mounting groove 1034 form a guide channel. The extension direction of the guide channel is at an angle to the height direction and the front-back direction. The upper end of the guide channel is connected to the lower edge of the bearing housing, and the lower end is connected to the first drain hole 1035. This can better prevent condensate from sliding out of the bearing housing mounting groove 1034 and guide the condensate to the first drain hole 1035 more quickly.

[0408] Specifically, the inner wall surface of the bearing housing mounting groove 1034 opposite to the end face of the bearing housing is a vertical surface, and the water-blocking rib 10341 extends obliquely downwards and backwards.

[0409] In some embodiments, as shown in FIG43, a water receiving plate 1032 is provided on the surface of the second end of the base 11 in the second direction. The water receiving plate 1032 and the base 11 surround the water receiving groove 10321 with the opening facing upward. The base 11 is provided with a second drain hole 1036 that connects the water receiving groove 10321 and the water receiving tray 26. The water receiving groove 10321 is located below the first drain hole 1035 and can receive condensate from the first drain hole 1035.

[0410] The top surface of the water receiving plate 1032 and the back surface of the base 11 extend in the left-right direction around the formed water receiving groove 10321 to the left and right ends of the base 11. The water receiving groove 10321 is used to receive all the condensate from the rear end face of the base 11 and the first water guide rib 1027. At this time, the condensate guided by the first drain hole 1035 and the first water guide rib 1027 also flows into the water receiving groove 10321 and flows to the water receiving tray 26 through the second drain hole 1036. There is no need to set up an additional structure to guide this part of the condensate to the water receiving tray 26, thereby making the air conditioning drainage structure simple and the manufacturing cost low.

[0411] Specifically, the water receiving plate 1032 is a V-shaped plate structure with the opening facing downwards, that is, the height of the center position of the water receiving plate 1032 in the left and right directions is higher than the height of the two ends, and there are two second drain holes 1036 located at the two ends of the water receiving plate 1032 in the left and right directions respectively.

[0412] In some embodiments, as shown in FIG38, the top surface of the base 11 is provided with an upward-facing receiving groove, and the inner wall surface of the receiving groove is provided with a third drain hole 1037 extending to the second end of the base 11 in the second direction. The water receiving tank 10321 is located below the third drain hole 1037 and is able to receive condensate from the third drain hole 1037.

[0413] Because the upper part of the base 11 is close to the air duct, the temperature is lower, making it easy for condensation to form on the top surface of the base 11. By providing a receiving groove on the top surface of the base 11, the condensation can be effectively collected, preventing it from flowing randomly horizontally and dripping. Furthermore, by providing a third drain hole 1037 that communicates with the receiving groove and extends to the rear end face of the base 11, the condensation in the receiving groove can be guided through the third drain hole 1037 to the rear end face of the base 11, and finally guided by the second water guiding component to the water receiving tray 26. This effectively prevents dripping and also prevents condensation from accumulating in the receiving groove and failing to drain.

[0414] Specifically, the lower edge of the opening of the third drain hole 1037 at the receiving tank is at the same height as the lowest point of the receiving tank, thereby effectively ensuring that the condensate in the receiving tank is completely drained. There are multiple third drain holes 1037, which are arranged at intervals along the first direction.

[0415] In some embodiments, as shown in Figures 6 and 40, the indoor unit of the air conditioner further includes a water baffle 37, which includes a main body 371, a first connecting plate 372, and a side baffle 373. The main body 371 has a guide surface 3711 for guiding condensate to the drip tray 26. The first connecting plate 372 is disposed on the guide surface 3711 of the main body 371 and is adapted to be connected to the heat exchanger 13 so that the main body 371 is located below the exposed copper tubes of the heat exchanger 13. The side baffle 373 is disposed on the guide surface 3711 of the main body 371, and is parallel to the first connecting plate 372 and spaced apart along a first direction. The side baffle 373 is located on the side of the heat exchanger 13 opposite to it along the first direction.

[0416] The main board 371 is mounted on the heat exchanger 13 via the first connecting plate 372, such that the guide surface 3711 is located below the exposed copper pipes. Condensate dripping from the exposed copper pipes onto the guide surface 3711 flows down to the drip tray 26 under the guidance of the guide surface 3711. Simultaneously, a side baffle 373 is provided on the guide surface 3711 of the main board 371, and the side baffle 373 is located to the side of the heat exchanger 13. The side baffle 373 effectively blocks condensate splashing from the heat exchanger 13 in the first direction and guides the condensate to the drip tray 26, effectively preventing the condensate from affecting the air conditioner. Furthermore, by setting the first connecting plate 372 and the side baffle 373 to be parallel, the connection between the first connecting plate 372 and the heat exchanger 13 is convenient, and it also blocks some of the condensate splashing from the heat exchanger 13 in the first direction, thereby further improving the condensate blocking effect.

[0417] It should be noted that the side baffle 373 is located to the side of the exposed copper tubes of the heat exchanger 13. On the projection plane perpendicular to the first direction, the projections of the exposed copper tubes that are not directly above the water receiving pan 26 are all located within the projection plane of the side baffle 373.

[0418] In some embodiments, as shown in FIG6, a portion of the main body 371 is recessed relative to the other main body 371 toward the exposed copper tube of the heat exchanger 13, so as to form a clearance groove 3712 on the side of the main body 371 away from the guide surface 3711.

[0419] This ensures the guiding effect of the main board 371 on the condensate water while avoiding interference between the main board 371 and other components such as the cross-flow fan 151. The structure of the air conditioner at the water baffle 37 is compact and has a high space utilization rate.

[0420] Specifically, the outline of the clearance groove 3712 matches the outer outline of the cross-flow fan 151, such as a triangular groove that matches the corner position of the cross-flow fan 151.

[0421] In some embodiments, as shown in FIG40, the end face of the first connecting plate 372 facing away from the main body 371 is provided with a first slot 3721. The first slot 3721 passes through the first connecting plate 372 in a first direction, and the first connecting plate 372 is sleeved on the exposed copper tube of the heat exchanger 13 through the first slot 3721.

[0422] Therefore, by aligning the first slot 3721 with the corresponding copper pipe and applying a certain external force to the water baffle 37 in the direction of approaching the copper pipe, the copper pipe can be clamped in the first slot 3721, thus realizing the installation of the water baffle 37 on the heat exchanger 13. The installation of the water baffle 37 is simple and convenient.

[0423] Specifically, the first slot 3721 has at least one narrow opening along its depth direction, the width of which is smaller than the diameter of the copper tube. During the process of the copper tube being inserted into the first slot 3721, it will compress the first connecting plate 372 to deform so as to pass through the narrow opening, thereby achieving a reliable connection between the copper tube and the first connecting plate 372.

[0424] The ion generator 38 of this embodiment has a frame through hole 1423 on the air guide frame 14, and a seat extension 116 extending forward at the front end of the base 11. The seat extension 116 is spaced apart from the air duct 12 and arranged adjacent to the air outlet 102. The ion generator 38 includes a probe 381 and a high-voltage transformer 382 electrically connected to each other. The probe 381 is disposed on the base 11, and the emitting end 3811 of the probe extends into the air duct 12 through the frame through hole 1423. The high-voltage transformer 382 is disposed on the seat extension 116, and the high-voltage transformer 382 and the probe 381 are electrically connected.

[0425] Specifically, as shown in Figures 43-46, the rear end of the air guide frame 14 is connected to the front end of the base 11. The through hole 1423 extends through the air guide frame 14 in the left-right direction and opens to the rear. By setting the probe 381 on the base 11 and setting the through hole 1423 on the air guide frame 14 to cooperate with the generating end 211 of the probe, and extending the emitting end 3811 of the probe into the air duct 12 through the through hole 1423, it is convenient that during the processing and / or assembly of the air guide frame 14 and the base 11, only the installation position of the probe 381 needs to be reserved on the air guide frame 14. If the ion generator 38 needs to be installed, the probe 381 can be installed at the corresponding installation position. The processing and / or assembly of the air guide frame 14 and the base 11 are simple, which in turn simplifies the processing and assembly of the air conditioner indoor unit and reduces costs.

[0426] During the manufacturing process of the indoor unit of the air conditioner, a through hole 1423 is reserved in the air guide frame 14 to cooperate with the generating end 211 of the probe. Only the mold of the air guide frame 14 needs to be adjusted. The through hole 1423 formed on the air guide frame 14 by interchangeable inserts reduces the complexity of the mold and does not require additional complex structural settings, thereby reducing costs.

[0427] In some embodiments, the base extension 116 is provided with a high-voltage pack mounting groove 11601 that extends through the base extension 116 in the vertical direction. By installing the high-voltage pack 382 in the high-voltage pack mounting groove 11601 and arranging the base extension 116 adjacent to the air outlet 102, since the base extension 116 protrudes forward from the base 11, the mounting position of the high-voltage pack 382 protrudes forward from the base 11, which facilitates the installation and maintenance of the high-voltage pack 382 and reduces the impact of the high-voltage pack 382 on other components.

[0428] Furthermore, in this embodiment, by simultaneously mounting the high-voltage transformer 382 and the probe 381 on the base 11, and with the probe 381 and the high-voltage transformer 382 located on the same side in the vertical direction, the connection between the probe 381 and the high-voltage transformer 382 is shortened while avoiding the need for a connector, making it easier for the high-voltage transformer 382 to be directly electrically connected to the probe 381, thereby reducing the cost of the ion generator 38.

[0429] Furthermore, by placing the transmitter 3811 of the probe near the air outlet 102 and extending the transmitter 3811 into the air duct 12, the positive ions and / or negative ions generated by the ion generator 38 can directly purify the air in the air duct 12 near the air outlet 102. The negative ions can also diffuse directly into the room with the air discharged from the air outlet 102, quickly covering the indoor space and improving the purification efficiency and effect of the ion generator 38.

[0430] In some embodiments, the base 11 has a mating plane 1424 orthogonal to the front-back direction, and the outer peripheral surface of the probe 381 is tangent to the mating plane 1424.

[0431] Specifically, as shown in Figures 43-46, the right front end face of the seat extension 116 is connected to the right rear end face of the air guide frame 14. In this embodiment, the outer peripheral surface of the probe's transmitting end 3811 is above and tangent to the mating plane 1424 on the base 11, so that the transmitting end 3811 of the probe extends into the air duct 12 through the frame through hole 1423 on the air guide frame 14.

[0432] In some embodiments, the front end of the base 11 is provided with a mounting slot 1400, and a portion of the probe 381 is fitted into the mounting slot 1400. Installing the probe 381 into the mounting slot 1400 facilitates the assembly of the probe 381 with the base 11 while simultaneously fixing the probe 381, thereby improving the stability of the probe 381.

[0433] In some embodiments, the base 11 includes a base body 1401, a first mating part 1402 and a second mating part 1403. The first mating part 1402 and the second mating part 1403 are disposed at the front end of the base body 1401 and spaced apart in the front-rear direction to form a base slot 1400. The probe 381 mates with the rear side surface 14021 of the first mating part and the front side surface 14031 of the second mating part. The rear side surface 14021 of the first mating part is a forward-protruding arc-shaped surface, and the front side surface 14031 of the second mating part is a rearward-recessed arc-shaped surface.

[0434] Specifically, as shown in Figures 43-46, the first mating part 1402 and the second mating part 1403 are spaced apart in the front-rear direction to form a seat groove 1400. By setting the rear side 14021 of the first mating part as a forward-protruding arc surface and the front side 14031 of the second mating part as a rearward-concave arc surface, it is convenient to install the probe 381 in the seat groove 1400. The front end of the probe 381 is limited by the first mating part 1402 and the rear end of the probe 381 is limited by the second mating part 1403, thereby improving the connection reliability between the probe 381 and the base 11.

[0435] In some embodiments, the base 11 further includes a first limiting portion 1404 and a second limiting portion 1405, which are arranged at intervals in the left-right direction. At least a portion of the probe 381 is engaged between the first limiting portion 1404 and the second limiting portion 1405. By limiting the probe 381 with the first limiting portion 1404 and the second limiting portion 1405, the probe 381 is prevented from moving in the left-right direction, thus improving stability.

[0436] In some embodiments, as shown in FIG43, the indoor unit of the air conditioner also includes a cross-flow fan 151. The cross-flow fan 151 is installed on the left side of the base 11, and the high-voltage transformer 382 and the probe 381 are installed on the right side of the base 11. By placing the high-voltage transformer 382 and the cross-flow fan 151 on the two sides of the indoor unit of the air conditioner, the distance between the high-voltage transformer 382 and the cross-flow fan 151 is increased, the static electricity accumulation on the cross-flow fan 151 is reduced, and the life of the cross-flow fan 151 is improved.

[0437] The water receiving tray 26 of this embodiment has a water receiving trough 261 extending along a first direction (the left-right direction as shown in FIG47). The water receiving tray 26 includes a first layer 262, a third layer 265 and a second layer 263 arranged sequentially in the vertical direction. The surface of the first layer 262 away from the second layer 263 forms the bottom surface of the water receiving tray 26. The surface of the second layer 263 away from the first layer 262 at least partially forms the wall surface of the water receiving trough 261. The outer edge of the first layer 262 in the second direction (the front-back direction as shown in FIG47) engages with the outer edge of the second layer 263 in the front-back direction.

[0438] Specifically, as shown in Figures 47-49, the first layer 262 is located below the second layer 263. In this embodiment, the water receiving tray is quickly assembled by engaging the front outer edge of the first layer 262 with the front outer edge of the second layer 263 and engaging the rear outer edge of the first layer 262 with the rear outer edge of the second layer 263. Through the connection of the first layer 262 and the second layer 263, the lower surface of the first layer 262 forms the outer wall of the water receiving tray 26, and the upper surface of the second layer 263 forms the inner wall of the water receiving tray 26. This simplifies the assembly structure of the water receiving tray 26, making it easier to manufacture and reducing the manufacturing cost of the water receiving tray 26.

[0439] As shown in Figure 48, the third layer 265 is an insulation layer. By setting an insulation layer between the first layer 262 and the second layer 263, the condensate in the drip tray 26 is prevented from directly contacting the outside air, thereby avoiding the phenomenon of condensation caused by a large temperature difference, and the insulation effect is better.

[0440] Compared to the related technology where a film is applied to the insulation layer to form the peripheral wall of the water receiving tray 261, applying a film to the insulation layer requires a very thick insulation layer. Increasing the thickness of the insulation layer increases the width of the water receiving tray 26, thereby affecting the air intake area of ​​the air conditioner indoor unit. In this embodiment, by setting an insulation layer between the first layer 262 and the second layer 263 and connecting them through the snap-fit ​​of the first layer 262 and the second layer 263, the width of the water receiving tray 26 can be reduced, thereby increasing the air intake area of ​​the air conditioner indoor unit.

[0441] Furthermore, in this embodiment, by placing the drain nozzle on the first layer 262 of the water receiving tray 26, the installation of the insulation layer is facilitated.

[0442] In some embodiments, the drip tray 26 includes a tray body 260 and a first tray extension 2662. The tray body 260 is provided with an extended drip tray groove 261 extending along a first direction (the left-right direction as shown in FIG. 47), which is used to receive condensate from the heat exchanger 13. The first tray extension 2662 is provided at least one end of the tray body 260 in the first direction, and the first tray extension 2662 is provided with a first extension groove 26621 extending along the width direction of the tray body 260 (the front-back direction as shown in FIG. 47), which is used to receive condensate from the wire clamping assembly 40 and the grounding wire on the heat exchanger bracket.

[0443] The left end of the heat exchanger 13 is provided with a pipe extending out of the heat exchanger 13, and the right end of the heat exchanger 13 is provided with a grounding plate 41 and a wire clamping assembly 40. A grounding wire is provided on the grounding plate 41, and the grounding wire passes through the wire clamping assembly 40 and is connected to the electrical control box. The wire clamping assembly 40 and the grounding wire passing through the wire clamping assembly 40 protrude forward from the surface of the heat exchanger 13. The water receiving tray 26 is used to receive the condensate on the surface of the heat exchanger 13, the condensate on the pipe extending from the end of the heat exchanger 13, and the condensate on the grounding wire and the wire clamping assembly 40 during the operation of the heat exchanger 13, so as to avoid the condensate from damaging other components of the air conditioner indoor unit and to prevent the condensate from flowing out through the air vent.

[0444] In this embodiment, a first plate extension 2662 extending forward is provided on the right end of the plate body 260. The first extension groove 26621 is connected to the plate water receiving groove 261. The first plate extension 2662 is located below the wire clamping assembly 40 and the grounding wire on the front right side of the heat exchanger 13, which facilitates the first extension groove 26621 to directly receive the condensate on the wire clamping assembly 40 and the grounding wire, and guides the condensate received by the first extension groove 26621 to the plate water receiving groove 261, thereby improving the reliability of water receiving.

[0445] In some embodiments, as shown in FIG47, the disc extension 266 further includes a second disc extension 2663. The first disc extension 2662 is located on the front right side of the disc body 260 and extends forward, such that the first disc extension 2662 is located below the wire clamping assembly 40 and the grounding wire, facilitating the first disc extension 2662 to directly receive condensate from the pipe extending from the left end of the heat exchanger 13. The second disc extension 2663 is located on the rear left side of the disc body 260 and extends rearward, such that the second disc extension 2663 is located below the pipe extending from the end of the heat exchanger 13, facilitating the first disc extension 2662 to directly receive condensate from the pipe extending from the left end of the heat exchanger 13. By setting the extension directions of the first tray extension 2662 and the second tray extension 2663 in opposite directions, the first tray extension 2662 can directly receive condensate from the wire clamping assembly 40 and the grounding wire, and the second tray extension 2663 can directly receive condensate from the pipe extending from the left end of the heat exchanger 13, thereby improving the water receiving reliability of the water receiving tray 26.

[0446] The indoor unit of the air conditioner in this embodiment further includes a water-drawing assembly 42. The inner wall surface of the air duct 12 includes a first wall surface 1103 and a second wall surface 1104. A heat exchanger 13 is disposed in the air duct and has a first end and a second end. The first end 14004 of the heat exchanger is opposite to the first wall surface 1103, and the second end 14005 of the heat exchanger is opposite to the second wall surface 1104. The water-drawing assembly 42 includes a first water-drawing strip 421 and a second water-drawing strip 423. The first water-drawing strip 421 is disposed on the first wall surface 1103, and the free end of the first water-drawing strip 421 abuts against the lower side of the first end 14004 of the heat exchanger. The second water-drawing strip 423 is disposed on the second wall surface 1104, and the free end of the second water-drawing strip 423 abuts against at least the lower side of the second end 14005 of the heat exchanger.

[0447] As shown in Figure 50, the first end 14004 of the heat exchanger is the rear end of the heat exchanger 13, the second end 14005 of the heat exchanger is the front end of the heat exchanger 13, the first wall surface 1103 is located behind the second wall surface 1104, the rear end of the heat exchanger 13 is arranged relative to the first wall surface 1103 located behind, and the front end of the heat exchanger 13 is arranged relative to the second wall surface 1104 located in front.

[0448] One end of the first water guide strip 421 is connected to the first wall surface 1103, and the other end of the first water guide strip 421, which is the free end of the first water guide strip 421, abuts against the lower side of the first end 14004 of the heat exchanger. The flow path of condensate on the first wall surface 1103 is interrupted. The first water guide strip 421 abuts against the lower side of the heat exchanger 13, so that the condensate on the first wall surface 1103 can flow towards the heat exchanger 13 along the extension direction of the first water guide strip 421, and flow into the water receiving tray 26 along the heat exchanger 13, thereby realizing the drainage of condensate on the first wall surface 1103.

[0449] As shown in Figure 50, the second end 14005 of the heat exchanger is arranged opposite to the second wall surface 1104. One end of the second water guide strip 423 is connected to the second wall surface 1104, and the other end of the second water guide strip 423, that is, the free end of the second water guide strip 423, abuts against the second end 14005 of the heat exchanger. By setting the second water guide strip 423, the flow path of condensate on the second wall surface 1104 can be interrupted. Since the free end of the second water guide strip 423 abuts against at least the lower side of the second end 14005 of the heat exchanger, the second water guide strip 423 can guide the condensate on the second wall surface 1104 to the heat exchanger 13, preventing the condensate on the second wall surface 1104 from flowing out and improving the user experience.

[0450] In this embodiment, the first end 14004 of the heat exchanger is arranged opposite to the first wall surface 1103 of the air duct 12, and the second end 14005 of the heat exchanger is arranged opposite to the second wall surface 1104. The first water guide strip 421 abuts against the lower side of the heat exchanger 13, so that the condensate on the first wall surface 1103 can flow towards the heat exchanger 13 along the extension direction of the first water guide strip 421. The second water guide strip 423 is provided so that the condensate on the second wall surface 1104 can be diverted to the heat exchanger 13, avoiding water leakage of the indoor unit of the air conditioner caused by the downward flow of condensate on the first wall surface 1103 and the second wall surface 1104. This achieves the diversion of condensate on the first wall surface 1103 and the second wall surface 1104, improving the user experience.

[0451] Furthermore, in this embodiment, by setting the first water guide strip 421 and the second water guide strip 423, the positions of the first water absorber 422 and the second water absorber 424 can be limited, the setting position of the first water absorber 422 can be standardized, and the uniformity of the setting position of the first water absorber 422 can be improved.

[0452] In some embodiments, as shown in FIG50, there are at least two second water guide strips 423, which are arranged at intervals in the front-to-back direction. The upper end of the second water guide strip 423 located on the front side is connected to the second wall surface 1104, and the lower end of the second water guide strip 423 located on the front side abuts against the lower side of the second end 14005 of the heat exchanger. The upper end of the second water guide strip 423 located on the rear side is connected to the second wall surface 1104, and the lower end of the second water guide strip 423 located on the rear side abuts against the upper side of the second end 14005 of the heat exchanger. By setting two second water guide strips 423, the flow path of condensate on the second wall surface 1104 is blocked from both the front and rear sides, preventing condensate on the second wall surface 1104 from flowing downward along the second wall surface 1104, ensuring the drainage effect of the second water guide strips 423, and thus improving the user experience.

[0453] In some embodiments, the second end 14005 of the heat exchanger has an upper side and a lower side, and at least two second water guide strips 423 are located between the upper side and the lower side of the second end of the heat exchanger 13. In this embodiment, by placing the second water guide strips 423 between the upper side 14051 and the lower side 14052 of the second end of the heat exchanger, it is convenient for the second water guide strips 423 to guide the condensate on the second wall surface 1104 to the heat exchanger 13, thereby improving the drainage effect.

[0454] As shown in FIG51, the air guide frame 14 of this embodiment has a frame mating part 1425 opposite to one end of the heat exchanger 13 of the air conditioner indoor unit. The frame mating part 1425 has a first side surface 14251 and a second side surface 14252 arranged opposite to each other in a third direction (vertical direction as shown in FIG51). The first side surface 14251 is adjacent to and opposite to one end of the heat exchanger 13. The frame mating part 1425 has a drain groove 14253, which penetrates the air guide frame 14 in a third direction and is used to guide the condensate on the air guide frame 14 to the heat exchanger 13 through the drain groove 14253.

[0455] Specifically, as shown in Figure 51, the lower end of the air guide frame 14 is opposite to the front end of the heat exchanger 13. The frame mating part 1425 of the air guide frame 14 refers to the part that abuts against the front end of the heat exchanger 13. The frame mating part 1425 is plate-shaped and has a first side 14251 and a second side 14252 in the vertical direction. The second side 14252 is located above the first side 14251. A drainage groove 14253 is provided on the frame mating part 1425 that penetrates the frame mating part 1425 in the vertical direction.

[0456] The air guide frame 14 of this embodiment has a drainage groove 14253 that extends through the thickness of the frame mating part 1425 of the air guide frame 14, and the frame mating part 1425 is opposite to one end of the heat exchanger 13. The drainage groove 14253 connects the heat exchanger 13 and the air guide frame 14, so that the condensate on the air guide frame 14 can flow to the heat exchanger 13 through the drainage groove 14253, and flow down along the heat exchanger 13 to the water collection tray, which facilitates the discharge of condensate on the air guide frame 14, improves the safety and reliability of the air conditioner indoor unit, and thus improves the user experience.

[0457] Furthermore, in this embodiment, the drainage groove 14253 of the bracket mating part 1425 on the air guide 14 facilitates the drainage of condensate on the air guide 14 to the heat exchanger 13 through the drainage groove 14253, thereby preventing the condensate on the air guide 14 from affecting other components of the air conditioner indoor unit and thus avoiding the problem of leakage or short circuit in the air conditioner indoor unit.

[0458] In some embodiments, as shown in FIG51, the second side surface 14252 is provided with a frame reinforcing rib 1426 extending along the length direction of the air guide frame 14, and the drainage groove 14253 is located on at least one side of the frame reinforcing rib 1426 in the width direction of the air guide frame 14. The second side surface 14252 is located above the first side surface 14251. By providing the frame reinforcing rib 1426 on the second side surface 14252, the structural strength of the frame mating part 1425 is improved, thereby improving the structural strength of the air guide frame 14.

[0459] In some embodiments, one end of the heat exchanger 13 has a recess 14054, and a drain groove 14253 is disposed in the area of ​​the air guide frame 14 opposite to the recess 14054. Because the drain groove 14253 and the recess 14054 are arranged opposite each other in the vertical direction, condensate first enters the recess 14054 and then enters the heat exchanger 13 through the recess 14054, preventing condensate from flowing downwards along the outer surface of the heat exchanger 13, thereby preventing condensate from dripping from the air inlet of the air conditioner indoor unit and improving the user experience.

[0460] In some embodiments, the drainage trough 14253 has a first limit position and a second limit position in the width direction of the air guide frame 14. The first limit position is located at the position of one second water guide strip 423 on the frame mating part 1425, and the second limit position is located at the position of another second water guide strip 423 on the frame mating part 1425.

[0461] Specifically, as shown in Figure 51, at least a portion of the drainage trough 14253 is disposed between the front side of the second water guide 423 located on the front side and the rear side of the second water guide 423 located on the rear side. The drainage trough 14253 may be disposed between the two second water guides 423, or at least a portion of the drainage trough 14253 may penetrate the second water guide 423 located on the front side, or at least a portion of the drainage trough 14253 may penetrate the second water guide 423 located on the rear side.

[0462] In this embodiment, two second water guide strips 423 limit the extreme positions of the drainage trough 14253 in the front-back direction, so that the condensate on the air guide frame 14 is guided through the drainage trough 14253. Part of the condensate flows directly to the heat exchanger 13, and the other part of the condensate is guided to the heat exchanger 13 through the second water guide strips 423, which prevents the condensate from flowing downward along the first side 14251 and improves the guiding effect of the condensate on the air guide frame 14.

[0463] As shown in Figure 52, the air guide plate 331 of this embodiment includes an outer air guide plate 3315, a cover plate 3316, and an inner liner plate 3317. The cover plate 3316 is disposed at at least one end of the outer air guide plate 3315 in the longitudinal direction (left-right direction as shown in Figure 52), and the cover plate 3316 is located on one side of the outer air guide plate 3315 in the thickness direction (front-back direction as shown in Figure 52). The inner liner plate 3317 is disposed on the outer air guide plate 3315, and the inner liner plate 3317 and the cover plate 3316 are located on the same side of the outer air guide plate 3315 in the thickness direction. The inner liner plate 3317 and the cover plate 3316 are arranged sequentially in the longitudinal direction of the outer air guide plate 3315 and are interlocked with each other.

[0464] Specifically, the cover plate 3316 is located on the rear side of the outer air guide plate 3315, and the inner lining plate 3317 is also located on the rear side of the outer air guide plate 3315. When the air guide plate 331 closes the air outlet of the indoor unit of the air conditioner, the cover plate 3316 and the inner lining plate 3317 are arranged facing the indoor unit of the air conditioner. When the air guide plate 331 opens the air outlet of the indoor unit of the air conditioner, the airflow at the air outlet is guided by the cover plate 3316 and the inner lining plate 3317 of the air guide plate 331.

[0465] The air guide plate 331 of this embodiment is configured by placing cover plates 3316 at both ends of the outer air guide plate 3315, and placing inner lining plates 3317 and cover plates 3316 on the same side of the thickness direction of the outer air guide plate 3315. The inner lining plates 3317 and cover plates 3316 are arranged sequentially in the left-right direction and interlocked with each other, so that the inner lining plates 3317 and the two cover plates 3316 form an integral structure, which improves the connection strength between the inner lining plates 3317 and cover plates 3316, and prevents the inner lining plates 3317 and cover plates 3316 from separating when the end of the air guide plate 331 is subjected to bending moment, thus preventing the air guide plate 331 from bending. This improves the structural strength of the air guide plate 331, thereby ensuring smooth airflow at the air outlet of the air conditioner indoor unit and improving the user experience.

[0466] In some embodiments, the cover plate 3316 has a plate extension 33162 extending toward the inner liner plate 3317. The side of the plate extension 33162 away from the outer air guide plate 3315 is adjacent to the outer air guide plate 3315 compared to the side of the cover plate 3316 away from the outer air guide plate 3315. A first plate engaging portion 33161 is provided on the plate extension 33162.

[0467] In this embodiment, by placing the first snap-fit ​​portion 33161 on the plate extension portion 33162 and making the rear side of the plate extension portion 33162 adjacent to the outer air guide plate 3315 compared to the rear side of the cover plate 3316, when the second snap-fit ​​portion 33171 on the inner lining plate 3317 snaps with the first snap-fit ​​portion 33161, the rear side of the inner lining plate 3317 is flush with the rear side of the cover plate 3316, which facilitates the inner lining plate 3317 and the cover plate 3316 in guiding the airflow at the air outlet.

[0468] In some embodiments, as shown in FIG52, the inner liner 3317 has a third snap-fit ​​portion 33172 on the side facing the outer air guide plate 3315, and the outer air guide plate 3315 has a fourth snap-fit ​​portion 33151 on the side facing the inner liner 3317. The third snap-fit ​​portion 33172 and the fourth snap-fit ​​portion 33151 are snapped together. By providing the third snap-fit ​​portion 33172 on the front side of the inner liner 3317 and the fourth snap-fit ​​portion 33151 on the rear side of the outer air guide plate 3315, the snap-fit ​​connection between the inner liner 3317 and the outer air guide plate 3315 forms an integrated structure, preventing the inner liner 3317 from separating from the outer air guide plate 3315 when the air guide plate 331 is subjected to bending moment, improving the connection stability between the inner liner 3317 and the outer air guide plate 3315, and thus improving the structural strength of the air guide plate 331.

[0469] Furthermore, in this embodiment, the inner lining plate 3317 can be connected to the fourth snap-fit ​​portion 33151 on the outer air guide plate 3315 via the third snap-fit ​​portion 33172, and can also be connected to the first snap-fit ​​portion 33161 on the cover plate 3316 via the second snap-fit ​​portion 33171 on the inner lining plate 3317. This allows the inner lining plate 3317 to be simultaneously connected to both the outer air guide plate 3315 and the cover plate 3316, effectively preventing the air guide plate 331 from bending forward or backward, improving the air guiding performance of the air guide plate 331, making the airflow at the air outlet smoother, and thus reducing the energy consumption and noise of the air conditioner indoor unit.

[0470] As shown in Figure 16, the frame 10 of this embodiment includes a frame body 1101 and a front panel 1102. The front panel 1102 is located at the front end of the frame body 1101 and below the air outlet 102. The front panel extends from top to bottom and is arranged at an angle to the rear. The angle α18 between the front panel 1102 and the vertical plane is 6°-14°.

[0471] Specifically, as shown in Figure 53, the front side 11021 of the front panel forms the front end face of the frame 10. The front side 11021 of the front panel extends from top to bottom and is arranged at an angle to the rear, such that the upper end of the front side 11021 of the front panel is located in front of the lower end of the front side 11021 of the front panel.

[0472] Compared to the related technologies where the front side 11021 of the front panel extends vertically and is parallel to the vertical plane, or where the front side 11021 of the front panel extends from top to bottom and is arranged at an angle forward, when the airflow of the air outlet 102 flows downward along the front side 11021 of the front panel, part of the airflow is easy to flow back to the air inlet 101, and another part of the airflow is easy to flow upward but not easy to flow downward, making it difficult to achieve the landing of the airflow.

[0473] The frame 10 of this embodiment extends from top to bottom and is arranged at an angle to the rear via the front side 11021 of the front panel, such that the lower end of the front side 11021 is located behind the upper end of the front side 11021. The air outlet 102 opens forward and is located above the front panel 1102. The airflow from the air outlet 102 flows downward along the extension direction of the front panel 1102. Due to the angled rearward arrangement of the front side 11021, the front side 11021 guides the airflow to flow downward along the front side 11021. The further downward the airflow flows, the further backward the front side 11021 is from the vertical plane, making it easier for the airflow to flow downward and reach the ground. This also increases the distance the airflow travels on the ground.

[0474] Furthermore, the rear side 11022 of the front panel extends from top to bottom and is arranged at a backward inclination. The rear side 11022 of the front panel is arranged parallel to the front side 11021 of the front panel. The angle θ18 between the rear side 11022 of the front panel and the direction of the air inlet 101 is 90°-150°. In this embodiment, by limiting the angle between the front side 11021 of the front panel and the vertical plane and the angle between the rear side 11022 of the front panel and the direction of the air inlet 101, it is avoided that the angle between the front side 11021 of the front panel and the vertical plane is too large, making it difficult for the airflow to flow downward along the front side 11021 of the front panel. At the same time, it is also avoided that the angle between the front side 11021 of the front panel and the vertical plane is too small, which would not have a guiding effect. This ensures that the front side 11021 of the front panel better guides the airflow from the air outlet 102 downward, while reducing the area of ​​the air duct 12 occupied by the rear side 11022 of the front panel and increasing the area of ​​the air duct 12.

[0475] In some embodiments, the air guide plate 331 is rotatably connected to the frame body 1101 to open and close the air outlet 102. When the air outlet 102 is closed, the front side 3318 of the air guide plate extends from top to bottom and is arranged at a rearward inclination, such that the upper end of the front side 3318 of the air guide plate is located in front of the lower end of the front side 3318 of the air guide plate, which facilitates the flow of air.

[0476] In some embodiments, the air guide plate 331 extends from top to bottom and is arranged at a backward inclination, such that the upper end of the air guide plate 331 is located in front of the lower end of the air guide plate 331, which facilitates the adjustment of the air outlet angle of the airflow blown out of the air outlet 102 and improves comfort.

[0477] In some embodiments, the air guide plate 331 has a first state. In the first state, the air guide plate 331 partially opens the air outlet 102, and at least a portion of the air guide plate 331 is opposite to the air outlet 102. In the first state, the shortest distance between the inner edge of the lower end of the air guide plate 331 and the upper end of the front panel 1102 is A18, and 60mm≤A18≤85mm. The lower end of the air guide plate 331 is separated from the frame 10 to partially open the air outlet 102, and the upper end of the air guide plate 331 is opposite to the air outlet 102. In this embodiment, by limiting the maximum distance between the inner edge of the lower end of the air guide plate 331 and the upper end of the front panel 1102 in the first state, it is convenient to adjust the air outlet angle of the partially opened air outlet 102 of the air guide plate 331, thereby facilitating better airflow guidance by the front panel 1102 and improving the landing effect.

[0478] Understandably, the first state is the air conditioner's indoor unit in the floor-standing airflow mode.

[0479] In some embodiments, in the first state, the angle between the tangent direction of the inner edge of the lower end of the air guide plate 331 and the vertical plane is β18, where 6°≤β18≤14°. By limiting the angle between the tangent direction of the inner edge of the lower end of the air guide plate 331 and the vertical plane, the air guide plate 331 can guide the airflow of the air outlet 102, reduce the flow resistance of the airflow at the air guide plate 331, and increase the air volume of the indoor unit of the air conditioner.
