[0037] The embodiments of the present disclosure are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present disclosure, but should not be understood as limiting the present disclosure.

[0038] like Figures 1 to 7 As shown, the air conditioner indoor unit of the present embodiment includes a base 1, a motor cover 2, and an air guide frame 3. Both the motor cover 2 and the air guide frame 3 are connected to the base 1. One of the motor cover 2 and the air guide frame 3 has a first insertion hole 31, and the other of the motor cover 2 and the air guide frame 3 has a first insertion buckle 21, which plugs into the first insertion hole 31. The air conditioner indoor unit can be wall-mounted.

[0039] For example, the air guide frame 3 is provided with a first plug hole 31 , and the motor cover 2 is provided with a first plug buckle 21 .

[0040] When assembling the air guide frame 3 of the air conditioner indoor unit of the disclosed embodiment, the motor cover 2 is first connected to the base 1. The first latch 21 is then engaged with the first socket 31, thereby positioning the air guide frame 3 and the base 1 relative to each other via the motor cover 2, thereby ensuring the relative position of the air guide frame 3 and the base 1. Afterwards, the air guide frame 3 is connected to the base 1. By first positioning the air guide frame 3 and the base 1 before connecting the air guide frame 3 to the base 1, the assembly accuracy of the air guide frame 3 is improved.

[0041] In some embodiments, as Figures 3 to 5 As shown, the plugging direction of the first buckle 21 is the front-to-back direction, and the first insertion hole 31 extends along the front-to-back direction. Figures 1 to 6 As shown,

[0042] For example, the first buckle 21 is inserted in a back-to-front direction, that is, the first buckle 21 is inserted into the first insertion hole 31 in a back-to-front direction. The air guide 3 can be installed in a front-to-back direction, and during installation, the first buckle 21 is inserted into the first insertion hole 31 in a back-to-front direction.

[0043] By designing the first insertion hole 31 to extend in the front-to-back direction and the first insertion buckle 21 to be inserted in the front-to-back direction, the air guide frame 3 can be positioned at least vertically after the first insertion buckle 21 is inserted and mated with the first insertion hole 31. This effectively prevents gaps in the air outlet duct formed between the air guide frame 3 and other components, thereby improving the performance of the air conditioner. Furthermore, the air guide frame 3 can be installed and removed in the front-to-back direction, eliminating the need for space in the vertical direction for removing the air guide frame 3 from the indoor air conditioner, facilitating ceiling-mounted installation of the indoor air conditioner.

[0044] In some embodiments, as Figure 4 As shown, the first buckle 21 includes a connected mating portion 211 and a guide portion 212. The guide portion 212 is arranged on one side of the mating portion 211 in the extension direction of the first socket 31. The mating portion 211 is plugged into the first socket 31, and the cross-sectional area of ​​the guide portion 212 gradually increases in the direction approaching the mating portion 211.

[0045] The cross-sectional area of ​​the guide portion 212 can be understood as the cross-sectional area of ​​the guide portion 212 cut by a plane perpendicular to the extending direction of the first insertion hole 31. For example, the cross-sectional area of ​​the guide portion 212 cut by a plane perpendicular to the front-to-back direction.

[0046] For example, Figure 4 As shown, the guide portion 212 is provided at the front side of the matching portion 211 , and the cross-sectional area of ​​the guide portion 212 gradually increases from the front to the rear.

[0047] By gradually increasing the cross-sectional area of ​​the guide portion 212 in the direction approaching the mating portion 211, the guide portion 212 plays a guiding role during the insertion of the first buckle 21 into the first socket 31, facilitating the plug-in mating of the first buckle 21 and the first socket 31, which is beneficial to improving the assembly efficiency of the air guide frame 3.

[0048] Of course, in other embodiments, the cross-sectional area of ​​the first buckle 21 may also be set to be equal everywhere.

[0049] In some embodiments, the first buckle 21 and the first insertion hole 31 are interference fit.

[0050] By performing interference fit between the first buckle 21 and the first insertion hole 31 , the fitting accuracy between the first buckle 21 and the first insertion hole 31 can be improved, thereby improving the positioning accuracy of the air guide frame 3 and further improving the assembly accuracy of the air guide frame 3 .

[0051] In some embodiments, as Figure 4 and Figure 5 As shown, the first buckle 21 includes a plurality of ribs 213 , one end of each rib 213 in the width direction is connected to one end of the other ribs 213 in the width direction, and the other end of the rib 213 in the width direction is at least partially cantilevered.

[0052] For example, Figure 4 and Figure 5 As shown, the first buckle 21 includes three ribs 213. The three ribs 213 are connected to each other at one end along the width direction, and the other ends of the three ribs 213 are cantilevered. When the first socket 31 is plugged into the first socket 31, the cantilevered ends of the ribs 213 abut against the wall of the first socket 31.

[0053] By configuring the first buckle 21 to include a plurality of ribs 213 , the ribs 213 can be elastically deformed when the first buckle 21 is plugged into the first insertion hole 31 , facilitating the insertion of the first buckle 21 into the first insertion hole 31 and improving the assembly efficiency of the air guide frame 3 .

[0054] Optionally, at least one rib 213 is a bent plate 214, the bent plate 214 includes a first part 2141 and a second part 2142 connected to each other, the second part 2142 is arranged on one side of the first part 2141 in the width direction of the bent plate 214, and the angle between the second part 2142 and the first part 2141 is an obtuse angle.

[0055] For example, Figure 4 and Figure 5 As shown, the two ribs 213 are bent plates 214. The width direction of the first portion 2141 is consistent with the left-right direction, and the second portion 2142 is arranged downwardly and tilted relative to the first portion 2141. The upper end of the second portion 2142 is connected to the first portion 2141, and the lower end of the second portion 2142 stops at the hole wall of the first insertion hole 31. Figures 1 to 6 shown.

[0056] By configuring rib plate 213 as a bent plate 214, the structural strength of rib plate 213 can be increased, thereby improving the reliability of the air conditioner indoor unit. Furthermore, configuring the angle between second portion 2142 and first portion 2141 as an obtuse angle effectively avoids stress concentration at the connection between second portion 2142 and first portion 2141, further improving the structural strength of rib plate 213.

[0057] Can be in the ground, such as Figure 5 As shown, the second portion 2142 includes a first width section 2143 and a second width section 2144 connected to each other. The second width section 2144 is provided on one side of the first width section 2143 in the extending direction of the first insertion hole 31, and the width of the second width section 2144 is greater than the width of the first width section 2143. The first width section 2143 is pluggably engaged with the first insertion hole 31, and the side of the second width section 2144 away from the first width section 2143 and the side of the second width section 2144 away from the first portion 2141 are both connected to the motor cover 2 or the air guide 3.

[0058] For example, Figure 5 As shown, the width of the first width section 2143 is L1, and the width of the second width section 2144 is L2, where L2 is greater than L1. The second width section 2144 is disposed behind the first width section 2143. The rear end and the lower end of the second width section 2144 are connected to the motor cover 2. The lower end of the first width section 2143 abuts against the wall of the first insertion hole 31.

[0059] By setting the second part 2142 to include a first width segment 2143 and a second width segment 2144, the connection area between the first buckle 21 and the motor cover 2 can be increased, the connection reliability between the first buckle 21 and the motor cover 2 can be improved, and the reliability of the air conditioner indoor unit can be further improved.

[0060] In some embodiments, as Figure 1 、 Figure 3 、 Figure 6 、 Figure 9 、 Figure 10 and Figure 11 As shown, the air conditioner indoor unit also includes an evaporator bracket 4, which is connected to the base 1. One of the evaporator bracket 4 and the air guide frame 3 is provided with a second insertion hole 32, and the other of the evaporator bracket 4 and the air guide frame 3 is provided with a second insertion buckle 41, which plugs into the second insertion hole 32. The evaporator bracket 4 is used to mount and secure the evaporator 5.

[0061] For example, Figure 6 、 Figure 8 and Figure 10 As shown, the air guide frame 3 is provided with a second plug hole 32 , and the evaporator bracket 4 is provided with a second plug buckle 41 .

[0062] When assembling the air guide frame 3, first connect the motor cover 2 and the evaporator bracket 4 to the base 1; then plug and match the first buckle 21 with the first socket 31, and plug and match the second buckle 41 with the second socket 32, so that the relative position of the air guide frame 3 and the base 1 is positioned through the motor cover 2 and the evaporator bracket 4, further improving the assembly accuracy of the air guide frame 3.

[0063] Alternatively, as Figure 1 As shown, the evaporator 5 is arranged on the lower side of the air guide frame 3, that is, the air outlet duct of the air conditioner indoor unit is an upward air outlet duct.

[0064] Optionally, the extending direction of the second insertion hole 32 is the same as the extending direction of the first insertion hole 31 , and the plugging direction of the second insertion buckle 41 is the same as the plugging direction of the first insertion buckle 21 .

[0065] For example, Figures 3 to 6 As shown, the plugging direction of the second plug buckle 41 and the plugging direction of the first plug buckle 21 are both front-to-back directions, and the first plug hole 31 and the second plug hole 32 both extend along the front-to-back direction.

[0066] For example, the second buckle 41 is inserted in a back-to-front direction, that is, the second buckle 41 is inserted into the second insertion hole 32 in a back-to-front direction. The air guide 3 can be installed in a front-to-back direction, and during installation, the second buckle 41 and the first buckle 21 are inserted into the second insertion hole 32 and the first insertion hole 31 in a back-to-front direction, respectively.

[0067] By making the extension direction of the second socket 32 ​​the same as that of the first socket 31 and the plugging direction of the second buckle 41 the same as that of the first buckle 21, the first buckle 21 can be plugged into and matched with the first socket 31 and the second buckle 41 can be plugged into and matched with the second socket 32 ​​at the same time during the installation of the air guide frame 3 along the same direction, thereby further improving the installation efficiency of the air guide frame 3.

[0068] Optionally, the first insertion hole 31 and the second insertion hole 32 both extend in the front-to-back direction, and the second insertion hole 32 and the first insertion hole 31 are provided on two different sides of the air guide frame 3 in the left-to-right direction.

[0069] It should be noted that when the user is facing the air conditioner indoor unit, the left side of the air conditioner indoor unit is the right side of the user, and the right side of the air conditioner indoor unit is the left side of the user.

[0070] For example, the second insertion hole 32 is arranged on the left side of the first insertion hole 31, and the second insertion buckle 41 is arranged on the left side of the first insertion buckle 21. In this case, the evaporator bracket 4 is the left bracket of the evaporator 5, and a right bracket can also be arranged on the right side of the evaporator 5 to achieve stable fixation of the evaporator 5 by using the left bracket and the right bracket.

[0071] By extending both the first insertion hole 31 and the second insertion hole 32 in the front-to-back direction, and arranging the second insertion hole 32 and the first insertion hole 31 on two different sides of the air guide frame 3 in the left-to-right direction, after the first plug buckle 21 is plugged into the first insertion hole 31 and the second plug buckle 41 is plugged into the second insertion hole 32, not only can the air guide frame 3 be positioned in the up-down direction and the left-to-right direction, but the air guide frame 3 can also be prevented from rotating around the axis extending in the front-to-back direction, thereby improving the positioning stability of the air guide frame 3 and further improving the assembly accuracy of the air guide frame 3.

[0072] In some embodiments, as Figures 8 to 10 As shown, one of the base 1 and the air guide frame 3 is provided with a third plug hole 11 , and the other one of the base 1 and the air guide frame 3 is provided with a third buckle 33 , which is plugged into and matched with the third plug hole 11 .

[0073] For example, the air guide frame 3 is provided with a third buckle 33 , and the base 1 is provided with a third plug hole 11 .

[0074] When assembling the air guide frame 3, first connect the motor cover 2 and the evaporator bracket 4 to the base 1; then plug and match the first buckle 21 with the first socket 31, plug and match the second buckle 41 with the second socket 32, and plug and match the third buckle 33 with the third socket 11, so that the relative position of the air guide frame 3 and the base 1 is positioned through the motor cover 2, the evaporator bracket 4 and the base 1, further improving the assembly accuracy of the air guide frame 3.

[0075] Optionally, an extending direction of the third plug hole 11 is the same as an extending direction of the first plug hole 31 , and an inserting direction of the third plug buckle 33 is the same as an inserting direction of the first plug buckle 21 .

[0076] For example, the plugging direction of the third plug buckle 33 and the plugging direction of the first plug buckle 21 are both front-to-back directions, and the first plug hole 31 and the third plug hole 11 both extend along the front-to-back direction.

[0077] For example, the third buckle 33 is inserted from back to front, that is, the third buckle 33 is inserted from back to front into the third insertion hole 11. The air guide 3 can be installed from front to back, and during installation, the third buckle 33 and the first buckle 21 are inserted from back to front into the third insertion hole 11 and the first insertion hole 31, respectively.

[0078] By making the extension direction of the third socket 11 the same as the extension direction of the first socket 31 and the plugging direction of the third buckle 33 the same as the plugging direction of the first buckle 21, the first buckle 21 can be plugged into and matched with the first socket 31 and the third buckle 33 can be plugged into and matched with the third socket 11 at the same time during the installation of the air guide frame 3 along the same direction, thereby further improving the installation efficiency of the air guide frame 3.

[0079] In some embodiments, as Figure 4 、 Figure 6 and Figure 10 As shown, the motor cover 2 is provided with a first fixing hole 22, the evaporator bracket 4 is provided with a second fixing hole 42, the base 1 is provided with a third fixing hole 12, and the air guide frame 3 is provided with a first connecting hole, a second connecting hole and a third connecting hole, as shown in FIG. Figure 11 As shown, the air conditioner indoor unit includes a first fastener 6, a second fastener 7, and a third fastener 8. The first fastener 6 passes through the first connecting hole and connects to the first fixing hole 22, thereby achieving a stable connection between the air guide frame 3 and the motor cover 2; the second fastener 7 passes through the second connecting hole and connects to the second fixing hole 42, thereby achieving a stable connection between the air guide frame 3 and the evaporator bracket 4; and the third fastener 8 passes through the third connecting hole and connects to the third fixing hole 12, thereby achieving a stable connection between the air guide frame 3 and the base 1.

[0080] The first fixing hole 22 , the second fixing hole 42 and the third fixing hole 12 may be threaded holes, and the first fastener 6 , the second fastener 7 and the third fastener 8 may be screws.

[0081] The installation and removal process of the air guide frame 3 in the indoor unit of the air conditioner according to the embodiment of the present disclosure:

[0082] First, connect the motor cover 2 and evaporator bracket 4 to the base 1. Then, install the air guide frame 3 from front to back, so that the first latch 21, the second latch 41, and the third latch 33 respectively engage with the first insertion hole 31, the second insertion hole 32, and the third insertion hole 11, thereby limiting the air guide frame 3 in the vertical and left and right directions. Afterwards, use the first fastener 6, the second fastener 7, and the third fastener 8 to achieve a stable connection between the air guide frame 3 and the motor cover 2, the evaporator bracket 4, and the base 1, thus completing the installation and fixation of the air guide frame 3. When disassembling the air guide frame 3, first remove the first fastener 6, the second fastener 7, and the third fastener 8, and then remove the air guide frame 3 from the back to the front.
