Description

Technical Field

[0001] The present invention relates to the technical field of air conditioners, and in particular to an air conditioner indoor unit and an air conditioner having the same. Background Art

[0002] With the development of economy, the use of air conditioners is becoming more and more widespread. For split air conditioners, if the indoor unit of the air conditioner is not cleaned for a long time, bacteria will easily grow inside the body due to moisture, dust accumulation and other reasons, which will have an adverse effect on the health of users.

[0003] However, the current cleaning of air conditioners is limited to surface cleaning, and it is impossible to perform deep cleaning inside the air duct. If you want to perform deep cleaning inside the air duct, you must disassemble the entire air duct. Since the air duct motor has a motor line connected to the electric control box, once the entire air duct is disassembled, the motor line of the air duct motor must be disconnected, which makes disassembly more difficult. Summary of the invention

[0004] The first object of the present invention is to provide an air conditioner indoor unit to solve the technical problem that it is difficult to disassemble the air duct.

[0005] The air conditioner indoor unit provided by the present invention comprises a display panel provided with a display box, and an air duct assembly, wherein the air duct assembly comprises an air duct and an air duct motor installed on the air duct, the air duct motor is electrically connected to the display box via a connecting terminal, the connecting terminal comprises a female end and a male end, one of the female end and the male end is arranged on the display panel, and the other is arranged on the air duct and electrically connected to the air duct motor, and the female end and the male end can be plugged and matched along a first direction; wherein the display panel and the air duct have a relatively separated state and a mutually combined state, when the display panel and the air duct are in a relatively separated state, the female end is disconnected from the male end; when the display panel and the air duct are in a mutually combined state, the female end is plugged into the male end.

[0006] When the air duct of the air conditioner indoor unit needs to be cleaned and maintained after a period of use, the air duct motor and the display panel are electrically connected through the female and male ends of the connection terminal. When the air duct is removed, the display panel and the air duct move away from each other, and the display panel and the air duct are in a relatively separated state. At the same time, the female end and the male end will follow the display panel and the air duct to make relative movements, respectively, to achieve disengagement, and complete the power-off operation of the air duct motor. At this time, the user can clean and maintain the removed air duct. After the cleaning and maintenance is completed, the user can reinstall the air duct. When the air duct is reinstalled to a state where it is combined with the display panel, the female end completes the plugging with the male end, thereby realizing the electrical connection between the air duct motor and the display panel, and then achieving the purpose of electrically connecting the air duct motor and the electric control box of the air conditioner indoor unit.

[0007] The air conditioner indoor unit utilizes the plug-in female end and the male end to realize the electrical connection between the duct motor and the display panel, so that when the duct needs to be cleaned and maintained, the duct can be directly removed after pushing the display panel. The female end and the male end of the connecting terminal are automatically disconnected in this process, so that the motor line of the duct motor and the electric control box are disconnected. There is no need to disassemble the connecting terminal separately, and the disassembly difficulty is small, which effectively improves the problem of difficulty in disassembling the duct in the prior art.

[0008] When the air duct cleaning and maintenance is completed, the air duct assembly can be directly reinstalled. During this process, the female end can be plugged into the male end to achieve rapid installation of the air duct. This arrangement facilitates the cleaning and maintenance of the air duct, thereby greatly improving the cleaning and maintenance efficiency of the air duct.

[0009] In addition, the structural form in which the female end and the male end are connected by plugging makes the male end have a strong wrapping property on the female end. During the operation of the air-conditioning indoor unit, the female end and the male end will not be separated due to misalignment, thereby ensuring the connection reliability of the connecting terminals.

[0010] Furthermore, the female end is arranged on the display panel and is detachably connected to the display panel; the male end is arranged on the air duct and is detachably connected to the air duct. With such arrangement, the female end and the male end can be removed from the display panel and the air duct respectively for maintenance.

[0011] Furthermore, the display box includes a horizontally arranged mounting seat, the mounting seat is located at the side of the display box, and the female end is arranged on the mounting seat. Such an arrangement can reduce the space occupied by the display panel in the vertical direction, thereby reducing the height dimension of the air conditioner indoor unit.

[0012] Furthermore, the female end is snap-fitted with the display panel; and / or the male end is snap-fitted with the air duct. This arrangement facilitates quick disassembly and assembly of the female end on the display panel and the male end on the air duct.

[0013] Furthermore, the display panel is provided with a clamping hole, and the female end is fixedly provided with a first clamping arm and a second clamping arm spaced apart from each other, the first clamping arm is provided with a first clamping protrusion on a side away from the second clamping arm, and the second clamping arm is provided with a second clamping protrusion on a side away from the first clamping arm, the first clamping arm and the second clamping arm can pass through the clamping hole and are clamped and fixed by the first clamping protrusion and the second clamping protrusion; the length direction of the first clamping arm and the second clamping arm extends along the second direction, and the second direction is at an angle to the first direction. This setting form of the clamping structure, on the one hand, facilitates the installation and removal of the female end, and on the other hand, can also play a certain limiting role on the female end, preventing the female end from detaching from the display panel during the separation process of the female end and the male end.

[0014] Furthermore, the outer wall of the female end partially extends outward to form a first flange, the display panel is provided with a first slide groove, the first flange and the first slide groove are slidably matched, and the relative sliding direction of the two is along the second direction. This arrangement realizes the guidance of the female end during installation to the display panel, avoids the jamming of the female end during installation, and thus improves the assembly efficiency.

[0015] Furthermore, the air duct is fixedly provided with a fixed wall and an elastic wall spaced apart from each other, the fixed wall and the elastic wall both extend along the first direction, wherein the elastic wall and the fixed wall form an elastic constriction, the elastic wall is provided with a bayonet, and the outer wall of the male end is provided with a clamping block, and the clamping block can be engaged with the bayonet after the male end is engaged with the elastic constriction. This arrangement of the clamping structure is simple in structure and facilitates quick disassembly and assembly of the male end relative to the air duct.

[0016] Furthermore, the fixed wall is provided with a second slide groove, the outer wall of the male end partially extends outward to form a second flange, the second flange is slidably matched with the second slide groove, and the relative sliding direction of the two is along the first direction. Such an arrangement can guide the male end to the air duct during installation, ensuring smoothness of the male end installation process.

[0017] Furthermore, the fixed wall is provided with a guide slope, the guide slope is communicated with the second slide groove, and the guide slope is configured to guide the second flange into the second slide groove. Such a configuration enables the second flange to accurately enter the second slide groove.

[0018] Furthermore, a retaining rib is provided at the end of the second flange, and a stopper is provided at the end of the second slide slot, and the retaining rib cooperates with the stopper in the direction in which the male end is inserted into the air duct. This arrangement can not only prevent the male end from being installed upside down during installation in the air duct, but also prevent the male end from being installed over-position.

[0019] Furthermore, a guide structure is provided between the female end and the male end, and the guide structure is configured to guide the female end to be plugged into the male end. In this way, when the cleaned air duct is reinstalled, the female end and the male end are guided by the guide structure, which facilitates accurate connection between the female end and the male end.

[0020] Furthermore, the guide structure includes a groove and a convex rib that are slidably matched along the first direction, wherein one of the groove and the convex rib is arranged on the inner wall of the male end, and the other is arranged on the outer wall of the female end. This setting form of the guide structure can guide the plugging process of the male end and the female end, and can also play a circumferential limiting role on the female end to prevent the female end from rotating in the male end.

[0021] Furthermore, the male end has an opening for the female end to enter, the opening is trumpet-shaped, and gradually decreases along the direction in which the female end is inserted into the male end, and the opening is configured to guide the female end to be inserted into the male end. This arrangement achieves guidance when the female end is inserted into the male end, and improves the assembly efficiency of the female end and the male end.

[0022] The second object of the present invention is to provide an air conditioner to solve the technical problem that the air duct is difficult to disassemble.

[0023] The air conditioner provided by the present invention comprises an air conditioner outdoor unit and the above-mentioned air conditioner indoor unit.

[0024] By setting the above-mentioned air-conditioning indoor unit in the air conditioner, the air conditioner accordingly has all the advantages of the above-mentioned air-conditioning indoor unit, which will not be described one by one here. BRIEF DESCRIPTION OF THE DRAWINGS

[0048] Usually, the duct motor of the air conditioner indoor unit is installed on the duct, and the motor wire is electrically connected to the main board in the electronic control box. When the duct needs to be deeply cleaned, the connection terminals between the motor wire and the main board need to be released during the process of removing the duct and the duct motor, which makes disassembly difficult.

[0049] In order to make the above-mentioned objects, features and advantages of the present invention more clearly understood, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0050] Embodiment 1

[0051] Figure 1 This is a schematic diagram of the structure of the display panel 010 and the air duct 020 of the air conditioner indoor unit provided in the first embodiment in a state of being combined with each other. Figure 2 This is a schematic diagram of the structure of the display panel 010 and the air duct 020 of the air conditioner indoor unit provided in the first embodiment in a relatively separated state. Figure 1 and Figure 2 As shown, this embodiment provides an air conditioner indoor unit, including a display panel 010 provided with a display box, and an air duct assembly, wherein the air duct assembly includes an air duct 020 and an air duct motor installed in the air duct 020, and the air duct motor is electrically connected to the display box through a connecting terminal 030. Specifically, the connecting terminal 030 includes a female end 100 and a male end 200, the female end 100 is provided on the display panel 010, the male end 200 is provided on the air duct 020 and is electrically connected to the air duct motor, and the female end 100 and the male end 200 can be plugged in and matched along a first direction. The display panel 010 and the air duct 020 are in a relatively separated state (refer to Figure 2 ) and the combined state (refer to Figure 1), when the display panel 010 and the air duct 020 are relatively separated, the female end 100 and the male end 200 are disconnected; when the display panel 010 and the air duct 020 are combined with each other, the female end 100 and the male end 200 are plugged.

[0052] When the air duct 020 needs to be cleaned and maintained after the air conditioner indoor unit has been used for a period of time, the air duct motor and the display panel 010 are electrically connected through the female end 100 and the male end 200 of the connection terminal 030. When the air duct 020 is removed, the display panel 010 and the air duct 020 move away from each other, and the display panel 010 and the air duct 020 are in a relatively separated state. At the same time, the female end 100 and the male end 200 will follow the display panel 010 and the air duct 020 to make relative movements, respectively, to achieve disengagement, and complete the power-off operation of the air duct motor. At this time, the user can clean and maintain the removed air duct 020. After the cleaning and maintenance is completed, the user can reinstall the air duct 020. When the air duct 020 is reinstalled to a state where it is combined with the display panel 010, the female end 100 completes the plugging with the male end 200, thereby realizing the electrical connection between the air duct motor and the display panel 010, and then achieving the purpose of electrically connecting the air duct motor to the electric control box of the air conditioner indoor unit.

[0053] The air conditioner indoor unit utilizes the plug-in female end 100 and the male end 200 to realize the electrical connection between the duct motor and the display panel 010, so that when the duct 020 needs to be cleaned and maintained, the duct 020 can be directly removed after pushing the display panel 010. The female end 100 and the male end 200 of the connecting terminal 030 are automatically disconnected in this process, so that the motor line of the duct motor and the electric control box are disconnected. There is no need to disassemble the connecting terminal 030 separately, and the disassembly difficulty is small, which effectively improves the problem of the difficulty of disassembling the duct 020 in the prior art.

[0054] When the cleaning and maintenance of the air duct 020 is completed, the air duct assembly can be directly reinstalled. During this process, the female end 100 can be plugged with the male end 200 to achieve rapid installation of the air duct 020. This arrangement facilitates the cleaning and maintenance of the air duct 020, thereby greatly improving the cleaning and maintenance efficiency of the air duct 020.

[0055] In addition, the structural form in which the female end 100 and the male end 200 are connected by plugging makes the male end 200 have a stronger wrapping property on the female end 100. During the operation of the air-conditioning indoor unit, the female end 100 and the male end 200 will not be separated due to misalignment, thereby ensuring the connection reliability of the connecting terminal 030.

[0056] In other embodiments, the female end 100 may be disposed on the air duct 020 and the male end 200 may be disposed on the display panel 010. In this case, the principle of removing the air duct 020 from the display panel 010 is the same as the above principle, so it will not be repeated.

[0057] It should be noted that Figure 2 The direction indicated by the arrows ab represents the first direction, that is, the plugging direction of the female end 100 and the male end 200 .

[0058] It should also be noted that, in the air-conditioning indoor unit provided in this embodiment, the display box is electrically connected to the main control board of the electric control box.

[0059] Specifically, five wires of the air duct motor are connected to the bottom of the male end 200. When the display panel 010 is pushed upward, the female end 100 is disconnected from the male end 200, and the connection terminal 030 is automatically unlocked. No manual removal is required, and disassembly is convenient. When the display panel 010 is pushed downward, the female end 100 is plugged into the male end 200, and the connection terminal 030 remains in an electrically connected state. At this time, the air duct motor remains in an electrically connected state with the display box, and indirectly maintains an electrically connected state with the main control board through the display box.

[0060] Please continue to refer to Figure 1 Specifically, in this embodiment, the air conditioner indoor unit is vertical.

[0061] Preferably, in this embodiment, the female end 100 is detachably connected to the display panel 010, and the male end 200 is detachably connected to the air duct 020. When the female end 100 and the male end 200 need to be maintained, the female end 100 and the male end 200 can be removed from the display panel 010 and the air duct 020 respectively, and then the female end 100 and the male end 200 can be maintained in a wide position, which is convenient for maintenance and avoids the situation where the user is inconvenient to operate due to limited space.

[0062] Please continue to refer to Figure 1 and Figure 2 In this embodiment, the display box includes a horizontally arranged mounting seat 040. Specifically, the mounting seat 040 is located at the side of the display box, and the female end 100 is arranged on the mounting seat 040. Such an arrangement can reduce the space occupied by the display panel in the vertical direction, thereby reducing the height size of the air conditioner indoor unit.

[0063] Specifically, in this embodiment, the female end 100 is clamped with the display panel 010, and the male end 200 is clamped with the air duct 020. This arrangement facilitates quick disassembly and assembly of the female end 100 on the display panel 010 and the male end 200 on the air duct 020.

[0064] In other embodiments, a threaded connector may be used to realize a detachable connection between the female end 100 and the display panel 010. Similarly, a threaded connector may be used to detachably connect the male end 200 and the air duct 020. It is understandable that only the female end 100 may be clamped with the display panel 010, while the male end 200 may be connected to the air duct 020 through a threaded connector, or only the male end 200 may be clamped with the air duct 020, while the female end 100 may be connected to the display panel 010 through a threaded connector.

[0065] Figure 3 for Figure 2 A magnified view of the local structure at point A. Figure 4 This is a partial structural diagram of the display panel 010 of the air conditioner indoor unit provided in the first embodiment when the female terminal 100 is installed. Figure 5 for Figure 4 The enlarged view of the local structure at B in the middle. Figure 6 This is a schematic diagram of the structure of the female end 100 of the connection terminal 030 of the air conditioner indoor unit provided in the first embodiment. Figure 1 and Figure 2 , and combined with Figures 3 to 6 In this embodiment, the mounting seat 040 is provided with a clamping hole 011, and the female end 100 is fixedly provided with a first clamping arm 110 and a second clamping arm 120 spaced apart from each other. Specifically, a first clamping protrusion 111 is provided on a side of the first clamping arm 110 away from the second clamping arm 120, and a second clamping protrusion 121 is provided on a side of the second clamping arm 120 away from the first clamping arm 110. The first clamping arm 110 and the second clamping arm 120 can pass through the clamping hole 011 and are clamped and fixed by the first clamping protrusion 111 and the second clamping protrusion 121. The length directions of the first clamping arm 110 and the second clamping arm 120 extend along the second direction, and the second direction is at an angle to the first direction.

[0066] When the female end 100 needs to be installed on the display panel 010, a force can be applied to the first clamping arm 110 and the second clamping arm 120 of the female end 100 to make the first clamping arm 110 and the second clamping arm 120 approach each other; then, the first clamping arm 110 and the second clamping arm 120 are pushed into the clamping hole 011 opened in the mounting seat 040; as the first clamping arm 110 and the second clamping arm 120 continue to move forward in the clamping hole 011, the first clamping protrusion 111 and the second clamping protrusion 121 also continue to move forward; when the first clamping protrusion 111 and the second clamping protrusion 121 are completely extended from the clamping hole 011, the first clamping protrusion 111 and the second clamping protrusion 121 will be clamped on the end face of the clamping hole 011, and the installation of the female end 100 is completed.

[0067] When the female end 100 needs to be removed from the display panel 010, the first clamping arm 110 and the second clamping arm 120 can be squeezed to bring them closer to each other so that the clamping hole 011 releases the limitation on the first clamping protrusion 111 and the second clamping protrusion 121. Then, the first clamping arm 110 and the second clamping arm 120 can be taken out of the clamping hole 011 to complete the disassembly of the female end 100.

[0068] This arrangement of the clip-on structure facilitates installation and disassembly of the female end 100. Furthermore, since the length directions of the first clip-on arm 110 and the second clip-on arm 120 are angled with the first direction, that is, the plug-in direction of the female end 100 and the display panel 010 is angled with the plug-in direction of the female end 100 and the male end 200, when the display panel 010 is separated from the air duct 020, the clip-on structure between the female end 100 and the display panel 010 can limit the female end 100 to a certain extent, thereby preventing the female end 100 from detaching from the display panel 010 during the separation process of the female end 100 and the male end 200.

[0069] Please continue to refer to Figure 3 and Figure 6 In this embodiment, the outer wall of the female end 100 partially extends outward to form a first flange 130, and the mounting seat 040 of the display panel 010 is provided with a first slide groove 012. Specifically, the first flange 130 and the first slide groove 012 are slidably matched, and the relative sliding direction of the two is along the second direction. Such a configuration realizes the guidance of the female end 100 during the installation process of the display panel 010, avoids the female end 100 from being stuck during the installation process, and thus improves the assembly efficiency.

[0070] Specifically, in this embodiment, two side walls of the female end 100 that are arranged opposite to each other are provided with first flanges 130 . Accordingly, there are two first slide grooves 012 , and the two first flanges 130 are respectively plugged and matched with the two first slide grooves 012 in a one-to-one correspondence.

[0071] Figure 7 This is a schematic diagram of a partial structure of the air duct 020 of the indoor unit of the air conditioner provided in the first embodiment when the male end 200 is installed. Figure 8 This is a schematic diagram of the structure of the male terminal 200 of the air conditioner indoor unit provided in this embodiment. Figure 1 and Figure 2 , and combined with Figure 7 and Figure 8In this embodiment, the air duct 020 is fixedly provided with a fixed wall 021 and an elastic wall 022 spaced apart from each other, wherein the fixed wall 021 and the elastic wall 022 both extend along the first direction, and the elastic wall 022 and the fixed wall 021 form an elastic constriction. Specifically, the elastic wall 022 is provided with a bayonet 023, and the outer wall of the male end 200 is provided with a clamping block 210, which can be engaged with the bayonet 023 after the male end 200 is inserted into the elastic constriction.

[0072] When the male end 200 needs to be installed on the air duct 020, the male end 200 can be first aligned with the elastic constriction formed by the fixed wall 021 and the elastic wall 022; then, the male end 200 is moved in the direction close to the elastic constriction; as the male end 200 moves, the clamping block 210 will slide on the elastic wall 022; when the clamping block 210 slides to the position of the clamping hole 023, the clamping block 210 will be clamped into the clamping hole 023, and the male end 200 is fixed on the air duct 020 by the clamping fit between the clamping block 210 and the clamping hole 023.

[0073] When the male end 200 needs to be removed from the air duct 020, a force can be applied to the elastic wall 022 to enlarge the elastic constriction formed by the elastic wall 022 and the fixed wall 021, so that the blocking block 210 exits the blocking hole 023; then, the male end 200 is moved in a direction away from the fixed wall 021 and the elastic wall 022, so as to remove the male end 200 from the air duct 020.

[0074] This arrangement of the snap-fit ​​structure is simple in structure and facilitates quick disassembly and assembly of the male end 200 relative to the air duct 020 .

[0075] Specifically, in this embodiment, there are two elastic walls 022, which are arranged opposite to each other and spaced apart. Such an arrangement enables the two side surfaces of the male end 200 to be engaged with the bayonet 023 on the elastic wall 022 at the same time, and the two opposite side surfaces of the male end 200 are stressed at the same time, thereby ensuring the reliability of the connection between the male end 200 and the air duct 020.

[0076] Please continue to refer to Figure 7 and Figure 8 In this embodiment, the fixed wall 021 is provided with a second slide groove 024, and the outer wall of the male end 200 partially extends outward to form a second flange 220, and the second flange 220 and the second slide groove 024 are slidably matched, and the relative sliding direction of the two is along the first direction. Such a configuration can guide the male end 200 during the installation process of the air duct 020, and ensure the smoothness of the installation process of the male end 200.

[0077] In this embodiment, a guide structure is provided between the female end 100 and the male end 200, and the guide structure is configured to guide the female end 100 to be plugged with the male end 200. In this way, when the cleaned air duct 020 is reinstalled, the female end 100 and the male end 200 are guided by the guide structure, which facilitates accurate connection between the female end 100 and the male end 200.

[0078] Please continue to refer to Figures 3 to 7 Specifically, the guide structure includes a groove 140 and a convex rib 230 that are slidably matched along a first direction, wherein the groove 140 is arranged on the outer wall of the female end 100 and the convex rib 230 is arranged on the inner wall of the male end 200 .

[0079] Such arrangement enables the convex rib 230 to slide in the groove 140 during the process of inserting the female end 100 into the male end 200, which not only guides the female end 100 during the process of inserting the female end 100 into the male end 200, but also, after the female end 100 is inserted into the male end 200, the convex rib 230 and the groove 140 cooperate to limit the female end 100 in the circumferential direction, thereby preventing the female end 100 from rotating in the male end 200.

[0080] Specifically, there are multiple grooves 140, which are arranged at intervals along the circumference of the outer wall of the female end 100. Correspondingly, there are multiple ribs 230, which are arranged at intervals along the circumference of the inner wall of the male end 200. The ribs 230 can slide and match with the grooves 140 in a one-to-one correspondence. Such an arrangement can ensure the balance of forces at various circumferential positions of the female end 100 and the male end 200, and reduce the jamming of the female end 100 and the male end 200 during the plugging process.

[0081] Please continue to refer to Figure 7 and Figure 8 In this embodiment, the male end 200 has an opening 240 for the female end 100 to enter, wherein the opening 240 is trumpet-shaped, and gradually decreases along the direction in which the female end 100 is inserted into the male end 200, and the opening 240 is configured to guide the female end 100 to be inserted into the male end 200. In this way, the female end 100 is guided when being inserted into the male end 200, and the assembly efficiency of the female end 100 and the male end 200 is improved.

Fig.11 This is a schematic diagram of the structure of the air duct 020 of the air conditioner indoor unit provided in the second embodiment. Fig.12 for Fig.11The enlarged view of the local structure at D in the middle. Fig.13 This is a schematic diagram of the structure of the male terminal 200 of the air conditioner indoor unit provided in the second embodiment. Figures 9 to 13 As shown, this embodiment provides another air-conditioning indoor unit, which is different from the air-conditioning indoor unit provided in the above-mentioned embodiment 1 in the following aspects.

[0084] Please continue to refer to Fig.10 and Fig.12 In this embodiment, the fixed wall 021 is provided with a guide slope 025 . Specifically, the guide slope 025 is communicated with the second slide groove 024 . The guide slope 025 is configured to guide the second flange 220 into the second slide groove 024 .

[0085] By providing the guiding inclined surface 025 , the second flange 220 can accurately enter the second sliding groove 024 , thereby guiding the male end 200 during installation in the air duct 020 , thereby improving the assembly efficiency of the male end 200 .

[0086] Please continue to refer to Fig.10 and Fig.12 In this embodiment, the number of the elastic wall 022 is one, and the elastic wall 022 is directly opposite to the fixed wall 021. When the male end 200 is installed in the air duct 020, the male end 200 is sandwiched between the fixed wall 021 and the elastic wall 022.

[0087] Please continue to refer to Fig.10 and Fig.12 In this embodiment, the guiding inclined surface 025 is arranged side by side with the second slide groove 024, that is, the bottom of the second slide groove 024 partially extends outward and tilts to form the guiding inclined surface 025. With such arrangement, the male end 200 can move toward the elastic shrinking direction between the fixed wall 021 and the elastic wall 022 under the guidance of the guiding inclined surface 025, so as to further improve the assembly efficiency of the male end 200.

[0088] Please continue to refer to Fig.12 and Fig.13 In this embodiment, a retaining rib 250 is provided at the end of the second flange 220, and a stop 026 is provided at the end of the second slide groove 024, wherein along the direction in which the male end 200 is inserted into the air duct 020, the retaining rib 250 and the stop 026 are engaged with each other.

[0089] When the male end 200 needs to be installed in the air duct 020, the end of the second flange 220 without the retaining rib 250 is directed toward the second slide groove 024, and then the second flange 220 is pushed into the second slide groove 024; when the male end 200 is snapped into place on the air duct 020, the retaining rib 250 provided on the male end 200 will cooperate with the stop 026. Such a setting can, on the one hand, prevent the male end 200 from being installed upside down during the installation process in the air duct 020, and play a fool-proof role; on the other hand, it also limits the installation stroke of the male end 200, and prevents the male end 200 from being installed over.

[0090] Fig.14 This is a structural diagram of a display panel of an air conditioner indoor unit provided in the second embodiment when a female end is installed. Fig.15 for Fig.14 The schematic diagram of the structure of the display panel and the female end is shown in the figure. Fig.16 This is a schematic diagram of the structure of the female end of the air conditioner indoor unit provided in the second embodiment. Figures 14 to 16 As shown, in the air conditioner indoor unit provided in the second embodiment, the mounting seat 040 of the display panel is provided with a through hole 016, and the female end is installed in the through hole 016. Specifically, the hole wall of the through hole 016 is provided with a limit strip 015, and the female end is installed in the through hole 016 from top to bottom and is limited by the limit strip 015; an elastic buckle 013 is formed partially on the hole wall of the through hole 016, and a slot 150 is provided on the upper edge of the female end. When the female end is installed in place in the through hole 016, the elastic buckle 013 is engaged in the slot 150, thereby fixing the female end in the through hole 016.

[0091] Preferably, in this embodiment, the hole wall of the through hole 016 is provided with a limit strip 015 at each position along the circumference thereof. Such a configuration enables each position of the circumference of the female end to be limited by the limit strip 015 when the female end is pulled out from the male end, and the limit is reliable.

[0092] In this embodiment, there are two card slots 150, which are respectively arranged on two opposite side walls of the female end. Accordingly, there are also two elastic buckles 013, which are respectively plugged and matched with the two card slots 150 in a one-to-one correspondence. Such arrangement ensures the connection reliability between the female end and the mounting seat 040, and effectively prevents the female end from falling off the mounting seat 040.

[0093] Please continue to refer to Fig.15 and Fig.16The outer periphery of the female end is provided with a plurality of guide grooves 160 extending from top to bottom, and correspondingly, the hole wall of the through hole 016 is provided with a plurality of guide strips 014, and the plurality of guide strips 014 are respectively plugged and matched with the plurality of guide grooves 160 in a one-to-one correspondence. Such a configuration can, on the one hand, realize the guidance of the female end during the installation process of the mounting seat 040, and on the other hand, can also limit the circumferential rotational freedom of the female end in the through hole 016, and prevent the female end from rotating in the through hole 016.

[0094] Please continue to refer to Fig.16 In this embodiment, the guide groove 160 is a blind groove with one end closed. This arrangement can provide a secondary limit effect on the downward movement of the female end, preventing the female end from leaving the mounting seat 040 from below the through hole 016.

[0095] Please continue to refer to Fig.16 Specifically, in this embodiment, the opening of the guide groove 160 is a bell-mouth structure. Such a configuration can provide a certain guide for the plugging process of the guide strip 014 and the guide groove 160, thereby improving the assembly efficiency of the female end and the mounting seat 040.
