[0043] The following describes in detail embodiments of the present invention, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present invention, and should not be construed as limiting the present invention.

[0044] Reference below Figures 1-9 A housing assembly 100 according to an embodiment of the first aspect of the present invention is described.

[0045] like Figure 1-Figure 7As shown, the housing assembly 100 according to the first embodiment of the present invention includes a housing 10 .

[0046] The shell 10 is formed with an air duct 101 and an air outlet connected to the air duct 101. A limiting groove 111 for installing the driving louver 30 is formed on the inner wall of the air duct 101 at one end near the air outlet. A bottom wall 1111 is formed in the limiting groove 111, which passes through the limiting groove 111 and is used to pass through an axial hole for the rotating shaft. A raised retaining rib 113 is formed on the inner wall of the air duct 101. The retaining rib 113 is located on the circumference of the windward side of the limiting groove 111 and extends along the circumference of the limiting groove 111.

[0047] For example Figure 5 and Figure 7 As shown, the ribs 113 on the windward side of the limiting groove 111 have the same height of protrusions, and the ribs 113 extend in a ring shape along the windward side of the limiting groove 111. Figure 3 As shown, the connection between the top surface of the blocking rib 113 and the side surface of the blocking rib 113 facing away from the limiting groove 111 adopts an arc transition connection, and the connection between the side surface of the blocking rib 113 facing away from the limiting groove 111 and the inner wall of the air duct 101 adopts an arc transition connection. As a result, the blocking effect on the cold air from the air duct 101 can be effectively reduced when the air-conditioning indoor unit is cooling, and the flow of cold air can be effectively guided.

[0048] In this embodiment, when the air conditioner is cooling, cold air continuously flows from the air duct 101 toward the air outlet. The raised retaining ribs 113 on the inner wall of the air duct 101 cause the cold air layer near the inner wall of the air duct 101 to change direction upon encountering the retaining ribs 113. Specifically, upon encountering the retaining ribs 113, the cold air layer near the inner wall of the air duct 101 continuously flows along the side surface of the retaining rib 113 facing away from the limiting groove 111 to the top surface of the retaining rib 113. Thereafter, under the guidance of the driving louvers 30, the cold air flows to the air outlet and is discharged from the air outlet.

[0049] In this way, the cold air can be effectively guided to flow along the side surface of the baffle 113 away from the limiting groove 111 toward the top surface of the baffle 113 and finally flow to the air outlet for discharge, thereby effectively reducing the amount of cold air directly flowing into the limiting groove 111 and the axial hole on the bottom wall 1111 of the limiting groove 111, thereby avoiding the formation of condensation on the drive motor 500 due to temperature difference, and effectively reducing the risk of condensation water droplets causing damage to electrical components, thereby effectively protecting the drive motor 500.

[0050] According to the shell assembly 100 of the embodiment of the present invention, by setting the shell 10 in the shell assembly 100, the shell 10 is formed with an air duct 101 and an air outlet connected to the air duct 101, and a limiting groove 111 for installing the driving shutter 30 is formed on the inner wall of the air duct 101 near the air outlet. A bottom wall 1111 passing through the limiting groove 111 is formed in the limiting groove 111 and is used to penetrate the shaft, wherein a raised retaining rib is formed on the inner wall of the air duct 101 113. The retaining rib 113 is located at the circumference of the windward side of the limiting groove 111 and extends along the circumference of the limiting groove 111. It can effectively reduce the amount of cold air flowing into the limiting groove 111 when the indoor unit of the air conditioner is cooling, thereby effectively reducing the amount of cold air flowing into the axial hole on the bottom wall 1111 of the limiting groove 111, thereby avoiding the formation of condensation water droplets on the drive motor 500 and preventing the drive motor 500 from short-circuiting and failing, thereby effectively reducing the failure rate and improving stability and reliability.

[0051] In one embodiment of the present invention, Figure 3 As shown, the raised height of the retaining rib 113 is greater than or equal to 1 mm and less than or equal to 2 mm. Specifically, the raised height of the retaining rib 113 is the height between the top surface of the retaining rib 113 and the inner wall of the air duct 101. For example, the raised height of the retaining rib 113 can be 1 mm, 1.2 mm, 1.4 mm, 1.6 mm, 1.8 mm, and 2 mm. Furthermore, the thickness of the retaining rib 113 is greater than or equal to 0.8 mm and less than or equal to 1 mm. For example, the thickness of the retaining rib 113 can be 0.8 mm, 0.84 mm, 0.88 mm, 0.92 mm, 0.96 mm, and 1 mm.

[0052] In this embodiment, the protruding height of the blocking rib 113 is set to be greater than or equal to 1 mm and less than or equal to 2 mm, which not only effectively ensures the guiding effect of the blocking rib 113 on the cold air flow, thereby effectively reducing the amount of cold air flowing into the limiting groove 111 and the shaft hole, but also avoids excessive flow resistance of cold air caused by the blocking rib 113 being too high, thereby effectively reducing the impact on the flow of cold air and ensuring the flow rate and efficiency of the cold air.

[0053] In one embodiment of the present invention, Figure 5 As shown, in the width direction of the air outlet, the end edge of either end of the retaining rib 113 is flush with the end edge of the limiting groove 111 or exceeds the end edge of the limiting groove 111. For example, the end edge of either end of the retaining rib 113 is flush with the end edge of the limiting groove 111; for another example, the end edge of either end of the retaining rib 113 exceeds the end edge of the limiting groove 111. In a specific example, Figure 5 As shown, the edge of either end of the retaining rib 113 is flush with the edge of the limiting groove 111 .

[0054] In this embodiment, in the width direction of the air outlet, the end edge of either end of the blocking rib 113 is set to be flush with or exceed the end edge of the limiting groove 111, which can ensure that the blocking rib 113 forms a complete windproof barrier around the windward side of the limiting groove 111, so that the cold air from the air duct 101 can be completely blocked on the windward side of the limiting groove 111, thereby ensuring the blocking effect of the blocking rib 113 on the cold air, and preventing the cold air from flowing from the windward side of the limiting groove 111 into the limiting groove 111 and the shaft hole.

[0055] In one embodiment of the present invention, Figure 5 As shown, the retaining rib 113 extends along the circumference of the limiting groove 111 into a U-shape toward the air outlet opening. Figure 5 As shown, the retaining ribs 113 are extended along the circumference of the windward side of the limiting groove 111 and the retaining ribs 113 are extended along the left and right edges of the limiting groove 111 .

[0056] When the indoor unit of the air conditioner is cooling, a part of the cold air on the windward side of the limiting groove 111 can flow along the side of the blocking rib 113 away from the limiting groove 111 toward the top surface of the blocking rib 113 and finally flow to the air outlet for discharge, and the other part can flow along the side of the blocking rib 113 away from the limiting groove 111 toward the end of the blocking rib 113 and finally flow to the air outlet for discharge.

[0057] In this embodiment, the blocking rib 113 is extended along the circumference of the limiting groove 111 into a U-shape toward the air outlet opening, which can not only effectively block the cold air from the windward side of the limiting groove 111 from flowing into the limiting groove 111 and the shaft hole, but also effectively block the cold air from the left and right sides of the limiting groove 111 from flowing into the limiting groove 111 and the shaft hole, thereby further ensuring the blocking effect of the blocking rib 113 on cold air, and preventing cold air from flowing into the limiting groove 111 and the shaft hole from the windward side of the limiting groove 111 and the left and right sides of the limiting groove 111.

[0058] In one embodiment of the present invention, Figure 5 and Figure 7 As shown, along the air outlet direction, the end of the blocking rib 113 facing the air outlet exceeds the edge of the limiting groove 111 facing the air outlet. Figure 5 and Figure 7 As shown, one end of the retaining rib 113 on the left side of the limiting groove 111 exceeds the edge of the side of the limiting groove 111 facing the air outlet, and one end of the retaining rib 113 on the right side of the limiting groove 111 exceeds the edge of the side of the limiting groove 111 facing the air outlet.

[0059] In this embodiment, along the air outlet direction, the end of the blocking rib 113 facing the air outlet is set to extend beyond the edge of the limiting groove 111 facing the air outlet, which can effectively prevent the cold air from flowing along the side of the blocking rib 113 away from the limiting groove 111 to the end of the blocking rib 113 and then flowing back into the limiting groove 111, thereby preventing the cold air from flowing back at the end of the blocking rib 113 and flowing into the limiting groove 111 and the shaft hole, thereby effectively enhancing the blocking effect of the blocking rib 113 on cold air.

[0060] In one embodiment of the present invention, Figure 3 and Figure 5 As shown, the side surface of the retaining rib 113 facing the limiting groove 111 is flush with the inner wall of the limiting groove 111. In this embodiment, by setting the side surface of the retaining rib 113 facing the limiting groove 111 to be flush with the inner wall of the limiting groove 111, the gap between the retaining rib 113 and the driving louver 30 can be effectively reduced, thereby ensuring smoother airflow when passing through the retaining rib 113, reducing turbulence, and further helping to maintain the uniformity and stability of the airflow at the air outlet, thereby effectively improving the air supply quality.

[0061] In one embodiment of the present invention, Figure 3 、 Figure 5 and Figure 7 As shown, the side wall of the limiting groove 111 close to the air outlet is the first side wall 1112. From the bottom wall 1111 of the limiting groove 111 toward the opening, the first side wall 1112 extends obliquely toward the air outlet.

[0062] In a specific example, Figure 5 As shown, the limiting groove 111 also has a second side wall 1113 and a third side wall. The second side wall 1113 is the side wall on the left side of the limiting groove 111, and the third side wall is the side wall on the right side of the limiting groove 111. Furthermore, an arc transition connection is adopted between the first side wall 1112 and the bottom wall 1111, an arc transition connection is adopted between the first side wall 1112 and the second side wall 1113, and an arc transition connection is adopted between the first side wall 1112 and the third side wall.

[0063] This embodiment sets the side wall of the limiting groove 111 close to the air outlet as the first side wall 1112, and the first side wall 1112 extends obliquely toward the air outlet from the bottom wall 1111 of the limiting groove 111 toward the opening, which can effectively optimize the flow direction of the cold air, guide the cold air to flow smoothly along the first side wall 1112 to the air outlet for discharge, and reduce the amount of cold air flowing back into the limiting groove 111, thereby further enhancing the air outlet effect of the air outlet and effectively reducing the amount of cold air flowing into the limiting groove 111.

[0064] In one embodiment of the present invention, Figure 3 、 Figure 5 and Figure 7 As shown, the angle between the first side wall 1112 and the bottom wall 1111 of the limiting groove 111 is less than or equal to 30°. For example, the angle between the first side wall 1112 and the bottom wall 1111 of the limiting groove 111 can be 30°, 28°, 26°, 24°, 22°, and 20°.

[0065] This embodiment can effectively reduce the resistance to the flow of cold air by setting the angle between the first side wall 1112 and the bottom wall 1111 of the limiting groove 111 to be less than or equal to 30°, thereby effectively ensuring the smoothness of the flow of cold air along the first side wall 1112, and further effectively reducing the possibility of airflow separation and turbulence, thereby effectively improving the overall flow efficiency of the airflow and preventing the cold air from flowing back into the limiting groove 111.

[0066] In one embodiment of the present invention, Figure 3 As shown, the limiting groove 111 is formed by a depression on the inner wall of the air duct 101. In this embodiment, by setting the limiting groove 111 to be formed by a depression on the inner wall of the air duct 101, not only can the structure be integrated, thereby effectively reducing the use of additional components, thereby effectively simplifying the structure and increasing the structural strength, but also the installation space can be optimized, making the product more compact.

[0067] In one embodiment of the present invention, Figure 1 and Figure 9 As shown, the shell 10 includes an air duct 101 plate, one side surface of the air duct 101 plate in the thickness direction is formed as a part of the inner wall of the air duct 101, a limiting groove 111 is formed on the air duct 101 plate, and the other side surface of the air duct 101 plate facing away from the air duct 101 is formed with an insulation area 112, and the projection of the limiting groove 111 on the other side surface of the air duct 101 plate is located in the insulation area 112, and the shell assembly 100 also includes: an insulation part, which is fixed to the air duct 101 plate and covers the insulation area 112.

[0068] For example, the retaining groove 111 is formed by a recessed depression in the air duct 101 plate, thereby achieving structural integration. The projection of the retaining groove 111 on the other side surface of the air duct 101 plate is located within the heat preservation area 112. In other words, the position of the retaining groove 111 is arranged relative to the position of the heat preservation area 112. At the same time, a heat preservation member is provided in the housing assembly 100, and the heat preservation member is fixed to the air duct 101 plate and covers the heat preservation area 112, thereby effectively ensuring that the components in the heat preservation area 112 can receive additional thermal insulation protection.

[0069] In this embodiment, a duct 101 plate is arranged in the shell 10 and an insulation component is arranged in the shell assembly 100. One side surface of the duct 101 plate in the thickness direction is formed as a part of the inner wall of the duct 101. A limiting groove 111 is formed on the duct 101 plate. The other side surface of the duct 101 plate facing away from the duct 101 is formed with an insulation area 112. The projection of the limiting groove 111 on the other side surface of the duct 101 plate is located in the insulation area 112. The insulation component is fixed to the duct 101 plate and covers the insulation area 112, which can effectively prevent heat exchange between cold air and the drive motor 500, thereby effectively reducing the risk of condensation water droplets on the drive motor 500, and thus effectively protecting the drive motor 500.

[0070] In one embodiment of the present invention, the thermal insulation member is adhesively connected to the air duct 101 plate. This embodiment, by arranging the thermal insulation member and the air duct 101 plate to be adhesively connected, not only effectively ensures the thermal insulation member is fixed to the air duct 101 plate, but also simplifies the installation process of the thermal insulation member, thereby effectively improving assembly efficiency and reducing assembly costs.

[0071] In one embodiment of the present invention, Figure 1 and Figure 9 As shown, a limiting rib 114 is provided on the side of the air duct 101 plate facing away from the air duct 101. The limiting rib 114 extends in a ring shape along the circumference of the axial hole, and the thermal insulation member is sleeved on the outside of the limiting rib 114. Furthermore, the thickness of the limiting rib 114 is greater than or equal to 1 mm and less than or equal to 1.5 mm. For example, the thickness of the limiting rib 114 can be 1 mm, 1.1 mm, 1.2 mm, 1.3 mm, 1.4 mm, and 1.5 mm.

[0072] This embodiment provides a limiting rib 114 on the side of the air duct 101 plate facing away from the air duct 101. The limiting rib 114 extends in a ring shape along the circumference of the shaft hole. The thermal insulation member is sleeved on the outside of the limiting rib 114. This prevents the thermal insulation member from affecting the swinging of the drive louver 30 after being installed on the air duct 101 plate, thereby effectively ensuring the reliability and stability of the swinging of the drive louver 30. In addition, the structural strength of the circumference of the shaft hole is enhanced.

[0073] In one embodiment of the present invention, the end surface of the limiting rib 114, which faces away from the limiting groove 111, extends beyond the side surface of the thermal insulation member facing away from the limiting groove 111. By setting the end surface of the limiting rib 114, which faces away from the limiting groove 111, beyond the side surface of the thermal insulation member facing away from the limiting groove 111, this embodiment effectively prevents the thermal insulation member from shifting or falling off during use, thereby increasing the stability of the thermal insulation member and ensuring that the thermal insulation member is always in the correct position. Furthermore, it provides mechanical protection for the thermal insulation member, thereby reducing the risk of damage to the thermal insulation member caused by external impacts.

[0074] In one embodiment of the present invention, the thermal insulation member is a sponge member having a thickness of 2 mm to 3 mm. It should be noted that sponge members generally have excellent thermal insulation properties, effectively reducing heat transfer, thereby facilitating temperature stability and effectively preventing condensation. For example, the thickness of the thermal insulation member may be 2 mm, 2.2 mm, 2.4 mm, 2.6 mm, 2.8 mm, or 3 mm.

[0075] This embodiment utilizes a sponge insulation member with a thickness of 2mm-3mm. This not only effectively ensures thermal insulation performance, thereby effectively reducing condensation, but also reduces weight and saves costs. Furthermore, the sponge member is easy to process and convenient to install and remove, thereby effectively improving the assembly efficiency of the insulation member.

[0076] An air-conditioning indoor unit according to an embodiment of the second aspect of the present invention includes a housing assembly 100 and a louver assembly according to the embodiment of the first aspect of the present invention.

[0077] The louver assembly is arranged at the air outlet position for adjusting the air outlet direction. The louver assembly includes multiple air guide louvers 300, a connecting rod 400 and a driving motor 500. The multiple air guide louvers 300 are connected by the connecting rod 400. One of the multiple air guide louvers 300 is formed as a driving louver 30. The driving end 31 of the driving louver 30 is arranged in the limiting groove 111. The driving motor 500 is connected to the driving end 31 of the driving louver 30 for driving the driving louver 30 to rotate.

[0078] For example, the number of air guide louvers 300 can be eight, nine, ten, eleven, twelve, or more. In a specific example, the number of air guide louvers 300 is ten, and one of the air guide louvers 300 is formed as a drive louver 30. Specifically, the drive motor 500 is provided with a motor shaft 50, which is connected to the drive end 31 of the drive louver 30. Furthermore, the connection between the motor shaft 50 and the drive end 31 of the drive louver 30 can be a snap-on connection.

[0079] The snap-fit ​​connection can speed up the installation process, effectively saving installation time and effectively improving production efficiency. In addition, the snap-fit ​​connection facilitates disassembly, making it very convenient when the drive motor 500 needs to be replaced or maintained. Maintenance personnel can easily separate the motor shaft 50 of the drive motor 500 from the drive louver 30, thereby removing the drive motor 500 and inspecting or replacing it without damaging the air duct 101 plate or other components. For example, a clamping portion is provided on the driving end 31 of the drive motor 500, which can be snap-fitted to the motor shaft 50 of the drive motor 500.

[0080] When the driving motor 500 is working, the motor shaft 50 of the driving motor 500 can drive the driving end 31 of the driving louver 30 to rotate, and the driving end 31 of the driving louver 30 can drive the driving louver 30 to rotate. Since the driving louver 30 connects multiple air guide louvers 300 together through the connecting rod 400, and each air guide louver 300 is rotatably connected to the connecting rod 400, the driving louver 30 can drive multiple air guide louvers 300 to rotate together through the connecting rod 400, thereby completing the air guiding function.

[0081] Furthermore, the unilateral swing angle of the air guide louver 300 is 0° to 60°, that is, the bilateral swing angle of the air guide louver 300 is 0° to 120°. When the drive louver 30 swings to the extreme left or right end, the drive louver 30 abuts against the left or right wall of the limiting groove 111. Thereafter, the drive louver 30 swings rightward or leftward, thereby completing the reciprocating swing of the air guide louver 300.

[0082] In one specific example, the air conditioner indoor unit is further provided with a chassis 600, a face frame, a fan 700, a panel, an air deflector, an electrical control box, and an evaporator. Furthermore, the chassis 600 and the housing assembly 100 can be integrally molded. This integral molding process eliminates any seams or connection points that may exist during assembly, thereby improving the structural integrity and rigidity of the entire air duct 101 panel, and further contributing to the overall strength and durability of the housing assembly 100. Furthermore, this process simplifies the production process, effectively reducing labor costs and production time.

[0083] According to the air-conditioning indoor unit of the embodiment of the present invention, by setting the shell assembly 100 of the first aspect mentioned above, the amount of cold air flowing into the limiting groove 111 can be effectively reduced when the air-conditioning indoor unit is cooling, thereby effectively reducing the amount of cold air flowing into the axial hole on the bottom wall 1111 of the limiting groove 111, thereby avoiding the formation of condensation water droplets on the drive motor 500 and preventing the drive motor 500 from short-circuiting and failing, thereby effectively reducing the failure rate and improving stability and reliability.
