[0001] Cross-references to related applications

[0002] This application is based on and claims priority to Chinese Patent Application No. 202411546754.7, filed on October 31, 2024, the entire contents of which are incorporated herein by reference. Technical Field

[0003] This application relates to the field of air conditioning technology, and in particular to a housing assembly and an indoor air conditioning unit having thereon. Background Technology

[0004] An air conditioner indoor unit typically includes a chassis with an air outlet. A louver assembly is installed at the air outlet, and the louver assembly contains multiple air guide louvers. One of the air guide louvers is a drive louver, which typically consists of blades and a support. The support passes through a shaft hole in the bottom wall of the mounting slot for mounting the drive louver and is connected to the motor shaft of the drive motor. The drive motor can drive the drive louver to rotate.

[0005] In the existing technology, there is a gap between the support of the drive louver and the side wall of the mounting groove. When the air conditioner is cooling, cold air can flow in from between the support and the side wall of the mounting groove and flow out from the shaft hole. After the air conditioner has been cooling for a long time, condensation droplets will form on the drive motor under the action of cold air, which may lead to a short circuit in the motor and thus affect the user experience.

This can effectively reduce the amount of cold air flowing into the limiting groove when the indoor unit of the air conditioner is cooling, thereby effectively reducing the amount of cold air flowing into the shaft hole on the bottom wall of the limiting groove. This can prevent condensation on the drive motor and prevent short circuit failure of the drive motor, thereby effectively reducing the failure rate and improving stability and reliability.

Detailed Implementation

[0037] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0038] The housing assembly 100 according to an embodiment of the first aspect of this application is described below with reference to Figures 1-9.

[0039] As shown in Figures 1-7, the housing assembly 100 according to the first aspect of this application includes a housing 10.

[0040] The housing 10 has an air duct 101 and an air outlet communicating with the air duct 101. A limiting groove 111 for installing the drive louver 30 is formed on the inner wall of the air duct 101 near the air outlet. A bottom wall 1111 through the limiting groove 111 and a shaft hole for passing through the rotating shaft are formed in the limiting groove 111. A raised baffle 113 is formed on the inner wall of the air duct 101. The baffle 113 is located on the periphery of the windward side of the limiting groove 111 and extends circumferentially along the limiting groove 111.

[0041] For example, as shown in Figures 5 and 7, the protrusion height of the baffle 113 on the windward side of the limiting groove 111 is consistent, and the baffle 113 extends in a ring along the windward side of the limiting groove 111. Furthermore, as shown in Figure 3, the connection between the top surface of the baffle 113 and the side of the baffle 113 facing away from the limiting groove 111 is made by an arc transition connection, and the connection between the side of the baffle 113 facing away from the limiting groove 111 and the inner wall of the air duct 101 is made by an arc transition connection. Thus, the obstruction of cold air from the air duct 101 can be effectively reduced when the indoor unit of the air conditioner is cooling, and the flow of cold air can be effectively guided.

[0042] In this embodiment, when the indoor unit of the air conditioner is cooling, cold air flows continuously from the air duct 101 toward the air outlet. Under the action of the protruding baffle 113 on the inner wall of the air duct 101, the airflow layer of cold air near the inner wall of the air duct 101 can change the airflow direction when it encounters the baffle 113. Specifically, when the airflow layer of cold air near the inner wall of the air duct 101 encounters the baffle 113, it can flow continuously along the side of the baffle 113 away from the limiting groove 111 to the top surface of the baffle 113, and then flow to the air outlet under the guidance of the driving louver 30 and be discharged from the air outlet.

[0043] Therefore, the cold air can be effectively guided to flow along the side of the baffle 113 away from the limiting groove 111 towards the top surface of the baffle 113 and finally flow to the air outlet for discharge. This can effectively reduce the amount of cold air that flows directly into the limiting groove 111 and the shaft hole on the bottom wall 1111 of the limiting groove 111, thereby avoiding the phenomenon of condensation forming on the drive motor 500 due to temperature difference, and thus effectively reducing the risk of damage to electrical components by condensation droplets, thereby effectively protecting the drive motor 500.

[0044] According to the housing assembly 100 of the present application embodiment, a housing 10 is provided in the housing assembly 100. The housing 10 forms an air duct 101 and an air outlet communicating with the air duct 101. A limiting groove 111 for installing a drive louver 30 is formed on the inner wall of the air duct 101 near the air outlet. A bottom wall 1111 through the limiting groove 111 and a shaft hole for passing through the rotating shaft are formed in the limiting groove 111. A raised baffle 1 is formed on the inner wall of the air duct 101. 13. The baffle 113 is located on the periphery of the windward side of the limiting groove 111 and extends circumferentially along 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 shaft hole on the bottom wall 1111 of the limiting groove 111. This can prevent condensation on the drive motor 500 and prevent short circuit failure of the drive motor 500, thereby effectively reducing the failure rate and improving stability and reliability.

[0045] In one embodiment of this application, as shown in FIG3, the protrusion height of the baffle 113 is greater than or equal to 1 mm and less than or equal to 2 mm. Specifically, the protrusion height of the baffle 113 is the height of the top surface of the baffle 113 from the inner wall of the air duct 101. For example, the protrusion height of the baffle 113 can be 1 mm, 1.2 mm, 1.4 mm, 1.6 mm, 1.8 mm, and 2 mm. Further, the thickness of the baffle 113 is greater than or equal to 0.8 mm and less than or equal to 1 mm. For example, the thickness of the baffle 113 can be 0.8 mm, 0.84 mm, 0.88 mm, 0.92 mm, 0.96 mm, and 1 mm.

[0046] In this embodiment, the protrusion height of the baffle 113 is set to be greater than or equal to 1 mm and less than or equal to 2 mm. This not only effectively ensures the guiding effect of the baffle 113 on the cold airflow, 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 the cold air due to the baffle 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.

[0047] In one embodiment of this application, as shown in FIG5, in the width direction of the air outlet, the end edge of either end of the baffle 113 is flush with or extends beyond the end edge of the limiting groove 111. For example, the end edge of either end of the baffle 113 is flush with the end edge of the limiting groove 111; or, for another example, the end edge of either end of the baffle 113 extends beyond the end edge of the limiting groove 111. In a specific example, as shown in FIG5, the end edge of either end of the baffle 113 is flush with the end edge of the limiting groove 111.

[0048] In this embodiment, in the width direction of the air outlet, the edge of any end of the baffle 113 is set to be flush with or extend beyond the edge of the limiting groove 111. This ensures that the baffle 113 forms a complete windproof barrier around the windward side of the limiting groove 111, thereby completely blocking the cold air from the air duct 101 on the windward side of the limiting groove 111. This ensures the blocking effect of the baffle 113 on the cold air and prevents the cold air from flowing into the limiting groove 111 and the shaft hole from the windward side of the limiting groove 111.

[0049] In one embodiment of this application, as shown in FIG5, the baffle 113 extends circumferentially along the limiting groove 111 in a U-shape facing the air outlet opening. Specifically, as shown in FIG5, the baffle 113 extends circumferentially on the windward side of the limiting groove 111 and extends on the left and right sides of the limiting groove 111.

[0050] When the indoor unit of the air conditioner is cooling, part of the cold air on the windward side of the limiting groove 111 can flow along the side of the baffle 113 away from the limiting groove 111 toward the top surface of the baffle 113 and eventually flow to the air outlet for discharge. The other part can flow along the side of the baffle 113 away from the limiting groove 111 toward the end of the baffle 113 and eventually flow to the air outlet for discharge.

[0051] In this embodiment, the baffle 113 extends circumferentially along the limiting groove 111 into a U-shaped shape facing the air outlet opening. This not only effectively blocks cold air from flowing into the limiting groove 111 and shaft hole from the windward side of the limiting groove 111, but also effectively blocks cold air from flowing into the limiting groove 111 and shaft hole from the left and right sides of the limiting groove 111. This further ensures the blocking effect of the baffle 113 on the cold air, preventing cold air from flowing into the limiting groove 111 and shaft hole from the windward side of the limiting groove 111 and the left and right sides of the limiting groove 111.

[0052] In one embodiment of this application, as shown in Figures 5 and 7, along the air outlet direction, one end of the baffle 113 facing the air outlet extends beyond the side edge of the limiting groove 111 facing the air outlet. In a specific example, as shown in Figures 5 and 7, one end of the baffle 113 on the left side of the limiting groove 111 extends beyond the side edge of the limiting groove 111 facing the air outlet, and one end of the baffle 113 on the right side of the limiting groove 111 extends beyond the side edge of the limiting groove 111 facing the air outlet.

[0053] In this embodiment, along the air outlet direction, one end of the baffle 113 facing the air outlet is set to extend beyond the side edge of the limiting groove 111 facing the air outlet. This can effectively prevent cold air from flowing back into the limiting groove 111 when it reaches the end of the baffle 113 along the side of the baffle 113 away from the limiting groove 111. This prevents cold air from flowing back into the limiting groove 111 and the shaft hole at the end of the baffle 113, thereby effectively strengthening the blocking effect of the baffle 113 on cold air.

[0054] In one embodiment of this application, as shown in Figures 3 and 5, the side surface of the baffle 113 facing the limiting groove 111 is flush with the inner wall of the limiting groove 111. By making the side surface of the baffle 113 facing the limiting groove 111 flush with the inner wall of the limiting groove 111, this embodiment can effectively reduce the gap between the baffle 113 and the drive louver 30, thereby ensuring smoother airflow when passing through the baffle 113, reducing turbulence, and thus helping to maintain the uniformity and stability of the airflow at the air outlet, thereby effectively improving the air delivery quality.

[0055] In one embodiment of this application, as shown in Figures 3, 5 and 7, the side wall of the limiting groove 111 near the air outlet is a first side wall 1112. The first side wall 1112 extends obliquely toward the air outlet from the bottom wall 1111 of the limiting groove 111 toward the opening.

[0056] In a specific example, as shown in Figure 5, the limiting groove 111 also has a second sidewall 1113 and a third sidewall. The second sidewall 1113 is the left sidewall of the limiting groove 111, and the third sidewall is the right sidewall of the limiting groove 111. Furthermore, the first sidewall 1112 is connected to the bottom wall 1111 by an arc transition, the first sidewall 1112 is connected to the second sidewall 1113 by an arc transition, and the first sidewall 1112 is connected to the third sidewall by an arc transition.

[0057] In this embodiment, by setting the side wall of the limiting groove 111 near the air outlet as the first side wall 1112, the first side wall 1112 extends obliquely from the bottom wall 1111 of the limiting groove 111 towards the opening and towards the air outlet. This can effectively optimize the flow direction of cold air, guide the cold air to flow smoothly along the first side wall 1112 towards the air outlet, reduce the amount of cold air flowing back into the limiting groove 111, thereby further enhancing the air outlet's airflow effect and effectively reducing the amount of cold air flowing into the limiting groove 111.

[0058] In one embodiment of this application, as shown in Figures 3, 5, and 7, the included angle between the first sidewall 1112 and the bottom wall 1111 of the limiting groove 111 is less than or equal to 30°. For example, the included angle between the first sidewall 1112 and the bottom wall 1111 of the limiting groove 111 can be 30°, 28°, 26°, 24°, 22°, and 20°.

[0059] In this embodiment, by setting the included angle between the first sidewall 1112 and the bottom wall 1111 of the limiting groove 111 to less than or equal to 30°, the resistance to the flow of cold air can be effectively reduced, thereby ensuring the smoothness of the flow of cold air along the first sidewall 1112, and thus effectively reducing the possibility of airflow separation and turbulence. This can effectively improve the overall flow efficiency of the airflow and prevent the cold air from flowing back into the limiting groove 111.

[0060] In one embodiment of this application, as shown in FIG3, the limiting groove 111 is recessed into the inner wall of the air duct 101. By setting the limiting groove 111 to be recessed into the inner wall of the air duct 101, this embodiment not only achieves structural integration, thereby effectively reducing the use of additional components, thus effectively simplifying the structural construction and increasing structural strength, but also optimizes the installation space, thereby making the product more compact.

[0061] In one embodiment of this application, as shown in Figures 1 and 9, the housing 10 includes an air duct 101 plate. One side surface of the air duct 101 plate in the thickness direction is formed as part of the inner wall of the air duct 101. A limiting groove 111 is formed on the air duct 101 plate. A heat insulation area 112 is formed on the other side surface of the air duct 101 plate opposite to the air duct 101. The projection of the limiting groove 111 on the other side surface of the air duct 101 plate is located within the heat insulation area 112. The housing assembly 100 also includes a heat insulation member, which is fixed to the air duct 101 plate and covers the heat insulation area 112.

[0062] For example, the limiting groove 111 is recessed into the air duct 101 plate, thereby achieving structural integration. The projection of the limiting groove 111 on the other side surface of the air duct 101 plate is located within the insulation area 112. That is, the position of the limiting groove 111 is opposite to the position of the insulation area 112. At the same time, an insulation element is provided in the housing assembly 100, and the insulation element is fixed to the air duct 101 plate and covers the insulation area 112, thereby effectively ensuring that the components within the insulation area 112 can receive additional thermal insulation protection.

[0063] In this embodiment, by setting an air duct 101 plate in the housing 10 and setting a heat insulation component in the housing assembly 100, one side surface of the air duct 101 plate in the thickness direction is formed as part of the inner wall of the air duct 101, a limiting groove 111 is formed on the air duct 101 plate, and a heat insulation area 112 is formed on the other side surface of the air duct 101 plate opposite to the air duct 101. The projection of the limiting groove 111 on the other side surface of the air duct 101 plate is located in the heat insulation area 112. The heat insulation component is fixed to the air duct 101 plate and covers the heat insulation area 112, which can effectively prevent the heat exchange between the cold air and the drive motor 500, thereby effectively reducing the risk of condensation on the drive motor 500 and thus effectively protecting the drive motor 500.

[0064] In one embodiment of this application, the insulation component is bonded to the air duct 101 plate. By setting the insulation component and the air duct 101 plate to be bonded, this embodiment can not only effectively ensure the fixing effect of the insulation component to the air duct 101 plate, but also simplify the installation process of the insulation component, thereby effectively improving assembly efficiency and reducing assembly costs.

[0065] In one embodiment of this application, as shown in Figures 1 and 9, 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 shaft hole, and the heat insulation component is sleeved on the outside of the limiting rib 114. Further, 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.

[0066] In this embodiment, a limiting rib 114 is provided on the side of the air duct 101 plate away from the air duct 101. The limiting rib 114 extends in a ring shape along the circumference of the shaft hole. The insulation component is sleeved on the outside of the limiting rib 114. This can avoid the influence of the insulation component on the swing of the drive louver 30 after it is installed on the air duct 101 plate, thereby effectively ensuring the reliability and stability of the swing of the drive louver 30. In addition, it can also strengthen the structural strength of the circumference of the shaft hole.

[0067] In one embodiment of this application, the end face of the limiting rib 114 facing away from the limiting groove 111 extends beyond the side surface of the insulation component facing away from the limiting groove 111. This embodiment, by setting the end face of the limiting rib 114 facing away from the limiting groove 111 to extend beyond the side surface of the insulation component facing away from the limiting groove 111, effectively prevents the insulation component from shifting or falling off during use, thereby increasing the stability of the insulation component and ensuring that it is always in the correct position. Furthermore, it provides mechanical protection for the insulation component, thereby reducing the risk of damage caused by external impacts.

[0068] In one embodiment of this application, the insulation element is a sponge element with a thickness of 2mm-3mm. It should be noted that sponge elements typically have excellent thermal insulation properties, effectively reducing heat transfer and thus helping to maintain temperature stability, thereby effectively preventing condensation. For example, the thickness of the insulation element can be 2mm, 2.2mm, 2.4mm, 2.6mm, 2.8mm, and 3mm.

[0069] This embodiment uses a sponge-like insulation component with a thickness of 2mm-3mm. This not only effectively ensures thermal insulation performance and reduces condensation, but also reduces weight and saves costs. Furthermore, the sponge component is easy to process and convenient to install and disassemble, thus effectively improving the assembly efficiency of the insulation component.

[0070] An indoor air conditioning unit according to a second aspect of this application includes a housing assembly 100 and a louver assembly according to the first aspect of this application described above.

[0071] The louver assembly is located at the air outlet to adjust the air outlet direction. The louver assembly includes multiple air guide louvers 300, connecting rods 400 and drive motors 500. The multiple air guide louvers 300 are connected by connecting rods 400. One of the multiple air guide louvers 300 is formed as a drive louver 30. The drive end 31 of the drive louver 30 is located in the limiting groove 111. The drive motor 500 is connected to the drive end 31 of the drive louver 30 to drive the drive louver 30 to rotate.

[0072] 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 configured 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. Further, the connection between the motor shaft 50 and the drive end 31 of the drive louver 30 can be a snap-fit ​​connection.

[0073] The snap-fit ​​connection allows for a faster installation process, effectively saving installation time and thus improving production efficiency. Furthermore, the snap-fit ​​connection facilitates disassembly, making it very convenient to replace or maintain the drive motor 500. Maintenance personnel can easily separate the motor shaft 50 of the drive motor 500 from the drive louvers 30, thereby removing the drive motor 500 for inspection or replacement without damaging the air duct 101 plate or other components. For example, the drive end 31 of the drive motor 500 is provided with a locking part that can snap-fit ​​into the motor shaft 50 of the drive motor 500.

[0074] When the drive motor 500 is working, the motor shaft 50 of the drive motor 500 can drive the drive end 31 of the drive louver 30 to rotate. The drive end 31 of the drive louver 30 can drive the drive louver 30 to rotate. Since the drive 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 drive louver 30 can drive multiple air guide louvers 300 to rotate together through the connecting rod 400, thereby completing the air guiding function.

[0075] Furthermore, the swing angle of the air guide louver 300 on one side is 0° to 60°, that is, the swing angle of the air guide louver 300 on both sides is 0° to 120°. When the drive louver 30 swings to the leftmost or rightmost end, the drive louver 30 abuts against the left or right side wall of the limiting groove 111. After that, the drive louver 30 swings to the right or left, thereby completing the reciprocating swing of the air guide louver 300.

[0076] In a specific example, the indoor unit of the air conditioner also includes a chassis 600, a front frame, a fan impeller 700, a panel, an air guide plate, an electrical control box, and an evaporator. Furthermore, the chassis 600 and the housing assembly 100 can be manufactured using a one-piece molding process. One-piece molding eliminates seams or connection points that may exist during assembly, thereby improving the structural integrity and rigidity of the entire air duct 101 plate, and thus contributing to enhancing the overall strength and durability of the housing assembly 100. In addition, it simplifies the production process, effectively reducing labor costs and production time.

[0077] According to the embodiments of this application, by providing the housing assembly 100 of the first aspect, the air volume of cold air flowing into the limiting groove 111 can be effectively reduced when the air conditioner indoor unit is cooling, thereby effectively reducing the air volume of cold air flowing into the shaft hole on the bottom wall 1111 of the limiting groove 111, thereby preventing the generation of condensation droplets on the drive motor 500 and preventing short circuit failure of the drive motor 500, thereby effectively reducing the failure rate and improving stability and reliability.
