Description

Technical Field

[0001] This invention relates to the field of air conditioner technology, and more specifically, to an air conditioner indoor unit base and an air conditioner. Background Technology

[0002] Currently, high-power wall-mounted indoor units, such as those reaching 4 or 5 horsepower, are available on the market. For these high-power units, the overall length of the cross-flow fan is relatively large to ensure heat exchange efficiency. If a single cross-flow fan assembly is used, its length poses a risk of deformation during operation and interference with the air duct. Therefore, two cross-flow fan assemblies can be installed in series. However, these two tandem cross-flow fan assemblies require support at their connection point, but existing support rigidity at this connection point is insufficient, resulting in poor operational stability of the cross-flow fan assembly. Summary of the Invention

[0003] The first objective of this invention is to provide an air conditioner indoor unit base to solve the technical problem of insufficient support rigidity at the connection point of the two cross-flow fan assemblies.

[0004] The present invention provides an air conditioner indoor unit base, which includes an air outlet frame, an air duct, and a water channel. The water channel includes a front water channel and a rear water channel. The inner side of the air duct is provided with a support seat for supporting a cross-flow fan assembly. The air duct is connected to the lower side of the rear water channel and extends downward from the rear water channel. The lower end of the air duct is located in front of the rear water channel. The air outlet frame is connected to the lower end of the air duct, and the front water channel is connected to the upper side of the air outlet frame.

[0005] The rear end of the support base extends and connects to the inner side of the air duct section, the upper end of the support base is connected to the rear water duct section, the lower front end of the support base is connected to the air outlet frame section, and the upper front end of the support base is connected to the front water duct section.

[0006] The support base is integrally formed with the rear water channel section, the air duct section, the air outlet frame section, and the front water channel section.

[0007] The beneficial effects of the air conditioner indoor unit base of this invention are:

[0008] By integrally molding the support base to connect the front water channel section, rear water channel section, air outlet frame section, and air duct section, the range of direct connection between the support base and other parts can be significantly increased. This ensures that the support base is supported across most of its circumference, improving its rigidity. Simultaneously, the support base can also support the aforementioned front water channel section, rear water channel section, air outlet frame section, and air duct section at approximately the midpoint of the length of the air conditioner indoor unit base, preventing a decrease in rigidity due to excessive length. Furthermore, by using a support base, with the same material thickness, the support rigidity is significantly greater than supporting the cross-flow fan assembly using a separate sheet metal. Therefore, this solution effectively improves the support rigidity of the two tandem cross-flow fan assemblies at the intermediate connection point, enhancing the stability of the cross-flow fan assembly's movement.

[0009] In a preferred embodiment, the support base includes a radial support plate and a first axial support plate. The rear end of the radial support plate extends and connects to the inner side of the air duct section. The upper end of the radial support plate is connected to the front plate of the rear water duct section. The lower front end of the radial support plate is connected to the inner end of the air outlet frame section. The upper front end of the radial support plate is connected to the inner plate of the front water duct section. The first axial support plate is located between two spaced radial support plates. The two ends of the first axial support plate are respectively connected to the two opposite sides of the two radial support plates. The first axial support plate extends along the direction from the rear water duct section to the front water duct section.

[0010] By using radial support plates connected to the air duct section, the front water duct section, the rear water duct section, and the air outlet frame section, and the first axial support plate and the two spaced radial support plates forming a gate-shaped support structure, the first axial support plate can be used to support the radial support plates, and the stiffness of the support is significantly increased, which is beneficial to improving the stability of the cross-flow wind turbine assembly.

[0011] In a preferred embodiment, the first axial support plate includes a lower connecting portion and a lower bearing receiving portion. The lower bearing receiving portion is used to install a first bearing, and the lower connecting portion is used to connect with the pressure cap. The lower bearing receiving portion is connected to the lower connecting portion at both ends in the width direction of the air duct.

[0012] By providing a lower connecting part in the first axial support, it can be directly connected to the gland. That is, the part where the gland connects to the support base is closer to the first bearing, which is jointly held by the lower bearing housing of both the gland and the support base, thus improving the fixing effect on the first bearing. This is because if the connection point between the gland and the base is far from the first bearing, and neither the gland nor the support base is a perfectly rigid body, the fixing effect would be unsatisfactory if the first bearing vibrates. Therefore, the above solution helps reduce the vibration of the first bearing during the operation of the cross-flow wind turbine assembly, improving the stability of the cross-flow wind turbine operation.

[0013] In a preferred embodiment, the radial support plate includes a first radial support portion and a second radial support portion. The second radial support portion is located between the first radial support portion and the air duct portion. The rear end of the second radial support portion extends and connects to the inner side of the air duct portion. The lower front end of the second radial support portion is connected to the inner end of the air outlet frame portion. The distance between two spaced and oppositely arranged first radial support portions is less than the distance between two spaced and oppositely arranged second radial support portions. The two ends of the first axial support plate are respectively connected to the two opposite sides of the two first radial support portions.

[0014] By making the distance between the first radial support portion smaller than the distance between the second radial support portion, the overall thickness of the support base (the dimension of the support base in the length direction of the air conditioner indoor unit base) can be made to vary in a step, avoiding the support base of a single thickness from maintaining a long distance continuously in the height direction. This facilitates the extraction of the lower mold from below the base during injection molding, improves manufacturing convenience, and helps to improve manufacturing quality.

[0015] In a preferred embodiment, a backwater channel plate is provided on the rear side of the air duct section, and the backwater channel plate is connected to the support base; the support base further includes a second axial support plate, and the backwater channel plate is connected to the lower end of the second axial support plate. The second axial support plate extends inward relative to the air duct section, and the second axial support plate, the two opposing second radial support sections, and the backwater channel plate enclose each other to form a side mold groove.

[0016] Because one end of the second radial support is relatively sharp in the width direction of the air duct, that is, the tip of the second radial support is relatively sharp in the angled area between the air duct and the transition section, if the space between the two opposing second radial support parts is directly formed from below by the lower mold, this part of the mold will be relatively sharp, significantly increasing the difficulty of mold manufacturing, and even making it difficult to form. Therefore, a back channel plate is set to separate the above-mentioned area, allowing the slider forming this part of the area to move out of the mold from the side along the width direction of the air duct, thereby improving the convenience of processing and improving the processing quality. By having the slider exit the mold in this direction, the slider body forming the relatively sharp area is no longer the free end of the slider, but rather combines with the slider body on the outside along the width direction of the air duct, thus avoiding the formation of a sharp mold body, which also facilitates the smooth forming of the base.

[0017] The second axial support plate, in conjunction with the back channel plate, divides the space below the air duct into an area formed by the lower mold and an area formed by a slider that slides along the width of the air duct. These two areas do not interfere with each other, facilitating the forming of their respective regions. Furthermore, the second axial support plate can distribute the force to the back channel plate, thereby allowing the back channel plate to assist in bearing the load of the support base, reducing the force directly acting on the air duct from the support base, and minimizing the deformation of the air duct.

[0018] In a preferred embodiment, the support base further includes a third axial support plate, the two ends of which are respectively connected to the two opposite sides of the two second radial support portions; the air outlet frame includes an upper air outlet plate and a lower air outlet plate, the radial support plate is formed and connected to the upper air outlet plate and the lower air outlet plate, and the second axial support plate is connected to the lower air outlet plate.

[0019] By integrally molding the radial support plate to the upper and lower air outlet plates, not only can the upper and lower air outlet plates be supported at the center of the air outlet along its length, but the second axial support plate and the paired radial support plates can also separate the airflow generated by the two cross-flow impeller assemblies as much as possible, significantly reducing the mixing effect between the two air outlets.

[0020] In a preferred embodiment, the lower air outlet panel includes a first lower sub-side panel and a second lower sub-side panel arranged along the length of the air conditioner indoor unit base. The first lower sub-side panel and the second lower sub-side panel are connected by a connecting plate, and the connecting plate is provided with reinforcing ribs.

[0021] By incorporating reinforcing ribs, the rigidity between the first and second lower side plates can be effectively improved, thereby enhancing the overall rigidity of the air outlet frame. This location also coincides with one end of a second axial support plate of the support base, further contributing to better support for the support base.

[0022] The second objective of this invention is to provide an air conditioner that solves the technical problem of insufficient support stiffness at the connection point of the two cross-flow fan assemblies in existing systems.

[0023] The air conditioner provided by the present invention includes a wall-mounted indoor unit. The wall-mounted indoor unit includes a motor, a cross-flow fan assembly, and an air conditioner indoor unit base as described above. The cross-flow fan assembly includes a first fan assembly and a second fan assembly. The motor is driven and connected to the first fan assembly. The first fan assembly and the second fan assembly are coaxially arranged. One end of the first fan assembly connected to the second fan assembly is rotatably disposed on the support base.

[0024] By combining the first and second wind turbine components, the length of a single cross-flow wind turbine component can be reduced. Even if the cross-flow wind turbine deforms during long-term use, the radial deformation can be minimized. Furthermore, by using a support base to support the connection between the first and second wind turbine components, the overall structure of the two cross-flow wind turbine components can be constrained approximately at the midpoint of its length during operation, thus improving the operational stability of the cross-flow wind turbine.

[0025] In a preferred embodiment, the wall-mounted indoor unit further includes a first bearing and a pressure cap. The pressure cap is fixedly connected to the support base, the first bearing is installed between the support base and the pressure cap, and one end of the first impeller assembly connected to the second impeller assembly is rotatably disposed in the shaft hole of the first bearing.

[0026] By setting a pressure cap and a support base for fixed connection to clamp the first bearing, rotational support can be provided for the first and second wind turbine assemblies at their connection points, thereby ensuring the motion stability of the first and second wind turbine assemblies.

[0027] In a preferred embodiment, the pressure cap is provided with a central upper bearing groove, and the support base is provided with a central lower bearing groove. The central upper bearing groove and the central lower bearing groove together form a central bearing cavity for accommodating the first bearing.

[0028] The central bearing cavity is formed by utilizing the upper and lower central bearing grooves, which facilitates processing and manufacturing.

[0029] In a preferred embodiment, the pressure cap is provided with a threaded connector through hole, and the support base is provided with a threaded hole. The threaded connector through hole is used for the threaded connector to pass through and connect with the threaded hole; the pressure cap and the support base are provided with a snap-fit ​​structure that engages with each other.

[0030] By setting the above structure on the gland, not only can the gland be fastened to the support base, but the gland can also be positioned along the width direction of the air duct section, thereby ensuring the installation accuracy and stability of the bearings supporting the first and second wind turbine assemblies, which is conducive to improving the stability of the cross-flow wind turbine operation.

Detailed Implementation

[0052] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

[0053] Example 1:

[0054] Figure 1 This is a schematic diagram of the structure of the air conditioner indoor unit base provided in Embodiment 1 of the present invention; Figure 2 This is a cross-sectional view of the air conditioner indoor unit base provided in Embodiment 1 of the present invention at one location, wherein the cut-off position does not pass through the support base; as shown Figure 1 and Figure 2As shown, the air conditioner indoor unit base 100 provided in Embodiment 1 of the present invention includes an air outlet frame 110, an air duct 120, and a water duct. The water duct includes a front water duct 130 and a rear water duct 140. The inner side of the air duct 120 is provided with a support seat 160 for supporting the cross-flow fan assembly. The air duct 120 is connected to the lower side of the rear water duct 140. The air duct 120 bends downward from the rear water duct 140. The lower end of the air duct 120 is located in front of the rear water duct 140. The air outlet frame 110 is connected to the lower end of the air duct 120, and the front water duct 130 is connected to the upper side of the air outlet frame 110.

[0055] The rear end of the support base 160 extends and connects to the inner side of the air duct section 120, the upper end of the support base is connected to the rear water duct section 140, the lower front end of the support base is connected to the air outlet frame section 110, and the upper front end of the support base is connected to the front water duct section 130.

[0056] The support base is integrally formed with the rear water channel section 140, the air duct section 120, the air outlet frame section 110, and the front water channel section 130.

[0057] Specifically, in this embodiment, the air conditioner indoor unit base 100 includes a mounting support 150, a water channel, an air duct 120, and an air outlet frame 110. Taking the orientation during normal use as an example, the mounting support 150 is located at the rear of the air conditioner indoor unit base 100, and usually also at the top. When a wall-mounted air conditioner is installed indoors, the wall mounting plate (not shown in the figure) needs to be fixed to the wall first, for example, nailed to the wall, and then the main unit of the air conditioner indoor unit is hung on the wall mounting plate. The mounting support 150 is the partial area of ​​the air conditioner indoor unit base 100 that is mounted on the wall mounting plate.

[0058] Using the wall-mounted air conditioner's indoor unit in its normal installation position as the reference point, the side of the indoor unit closest to the wall is considered the rear side. Figure 2 The right side of the image represents the rear side of each component described in this application. The water channel section includes a front water channel section 130 and a rear water channel section 140. The front water channel section 130 is located at the front end of the air duct section 120, which has a generally upward-opening arc-shaped cross-section, while the rear water channel section 140 is located at the rear end of the air duct section 120. When the indoor unit of the air conditioner is in cooling mode, the condensation inside the air conditioner can fall into the front water channel section 130 and the rear water channel section 140, and collect and be discharged through the indoor unit drain pipe.

[0059] The air outlet frame 110 is located at the lower front of the air duct 120. The air outlet frame 110 can form an air outlet and can be equipped with an up-down sweeping assembly and / or a left-right sweeping assembly. The air outlet is connected to the interior of the air duct 120 to deliver the air generated by the cross-flow fan assembly to the wall-mounted air conditioner indoor unit for cooling or heating the user's space.

[0060] The air duct section 120 is the area for the rotation of the cross-flow fan assembly. Part of the cross-flow fan assembly is located in the air duct section 120, and the motor 230 that drives the cross-flow fan assembly can be installed at one end of the air duct section 120. In this embodiment, since two tandem cross-flow fan assemblies—a first fan assembly 210 and a second fan assembly 220—need to be set, a support base 160 is provided in the air duct section 120. One end of the first fan assembly 210 is connected to the motor 230, and the other end of the first fan assembly 210 is connected to one end of the second fan assembly 220. The end of the first fan assembly 210 connected to the second fan assembly 220 is rotatably mounted on the support base 160 through a first bearing 250.

[0061] It should be noted that in this embodiment, the integral molding of A with B and C means that A is in direct contact with both B and C, and does not mean that A is connected to B or C through other parts or components.

[0062] By integrally connecting the support base 160 to the front water channel section 130, rear water channel section 140, air outlet frame section 110, and air duct section 120, the range of direct connection between the support base 160 and other parts can be significantly increased. This ensures that the support base 160 is supported across most of its circumference, improving its rigidity. Simultaneously, the support base 160 can also support the aforementioned front water channel section 130, rear water channel section 140, air outlet frame section 110, and air duct section 120 at approximately the midpoint of the length of the air conditioner indoor unit base, preventing a decrease in rigidity due to excessive length. Furthermore, by using the support base 160, with the same material thickness, its support rigidity is significantly greater than that of supporting the cross-flow fan assembly using a separate sheet metal. Therefore, this solution effectively improves the support rigidity of the two tandem cross-flow fan assemblies at the intermediate connection point, enhancing the stability of the cross-flow fan assembly's movement.

[0063] Figure 3 This is a cross-sectional view of the air conditioner indoor unit base provided in Embodiment 1 of the present invention at one location, wherein the cut-off position is through the support base; Figure 4 for Figure 1 Enlarged view of a portion of the support base; as shown in the image. Figure 3 and Figure 4As shown, preferably, the support base 160 includes a radial support plate 161 and a first axial support plate 162. The rear end of the radial support plate 161 extends and connects to the inner side of the air duct portion 120. The upper end of the radial support plate 161 is connected to the front plate of the rear water duct portion 140. The lower front end of the radial support plate 161 is connected to the inner end of the air outlet frame portion 110. The upper front end of the radial support plate 161 is connected to the inner plate of the front water duct portion 130. The first axial support plate 162 is located between two spaced radial support plates 161. The two ends of the first axial support plate 162 are respectively connected to the two opposite sides of the two radial support plates 161. The first axial support plate 162 extends along the direction from the rear water duct portion 140 to the front water duct portion 130.

[0064] The system includes two radial support plates 161, which are called radial support plates because they extend approximately radially along the air duct portion 120. Both radial support plates 161 are approximately perpendicular to or perpendicular to the length direction of the base and are arranged along the length direction of the base. The first axial support plate 162 and the second axial support plate 163 are called axial support plates because they are parallel to the axis of the air duct portion 120. The first axial support plate 162 is located at the top of the support base 160, and the second axial support plate 163 is located in the region between the two radial support plates 161, at both ends in a direction perpendicular to the length of the air conditioner indoor unit base. In this embodiment, both the first axial support plate 162 and the second axial support plate 163 are perpendicular to the radial support plate 161.

[0065] By using radial support plates 161 integrally formed and connected to the air duct section 120, the front water duct section 130, the rear water duct section 140 and the air outlet frame section 110, and the first axial support plate 162 and the two spaced radial support plates 161 form a gate-shaped support structure, the first axial support plate 162 can be used to support the radial support plate 161, and the rigidity of the support is significantly increased, which is beneficial to improving the stability of the cross-flow fan assembly operation.

[0066] Figure 5 This is a schematic diagram of the structure of the air conditioner indoor unit base provided in Embodiment 1 of the present invention, viewed from above the air duct section; as shown. Figures 3-5 As shown, preferably, the first axial support plate 162 includes a lower connecting portion 1621 and a lower bearing receiving portion 1624. The lower bearing receiving portion 1624 is used to install the first bearing 250, and the lower connecting portion 1621 is used to connect with the pressure cover 240. The lower bearing receiving portion 1624 is connected to the lower connecting portion 1621 at both ends in the width direction of the air duct portion 120.

[0067] Specifically, the lower bearing receiving portion 1624 can be a generally semi-circular arc-shaped plate. The lower bearing receiving portion 1624 of the first axial support plate 162 and the top center area of ​​the radial support plate 161 form the central lower bearing groove described later. Moreover, the lower bearing receiving portion 1624 is also provided with an axial inner flange 1625 in the middle of the length direction of the air conditioner indoor unit base, which can axially position the first bearing 250.

[0068] In this embodiment, one lower connecting part 1621 is provided with a threaded hole 1622, and the other lower connecting part 1621 is provided with a threaded hole 1622 and a slot 1623. The slot 1623 can cooperate with the latch 242 located on the cover 240, and the threaded hole 1622 can be threadedly connected with a screw passing through the cover 240 from top to bottom to fix the cover 240 to the support base 160. In addition, two radial positioning parts 241 are provided on the lower surface of the cover 240, such as radial positioning blocks or radial positioning posts. The two radial positioning parts 241 respectively cooperate with the outer end faces of the two lower connecting parts 1621 at both ends in the width direction of the air duct 120, thereby realizing the positioning of the cover 240 relative to the support base 160 in the width direction of the air duct 120.

[0069] By providing a lower connecting portion 1621 in the first axial support portion, it can be directly connected to the pressure cap 240. That is, the part where the pressure cap 240 connects to the support base 160 is closer to the first bearing 250 jointly held by the lower bearing receiving portion 1624 of the pressure cap 240 and the support base 160, which can improve the fixing effect of the first bearing 250. This is because if the position where the pressure cap 240 connects to the air conditioner indoor unit base 100 is far from the first bearing 250, and neither the pressure cap 240 nor the support base 160 is an absolutely rigid body, the fixing effect will not be ideal if the first bearing 250 vibrates. Therefore, the above solution helps to reduce the vibration of the first bearing 250 when the cross-flow fan assembly is running, and improves the stability of the cross-flow fan operation.

[0070] like Figure 3 and Figure 4 As shown, preferably, the radial support plate 161 includes a first radial support portion 1611 and a second radial support portion 1612. The second radial support portion 1612 is located between the first radial support portion 1611 and the air duct portion 120. The rear end of the second radial support portion 1612 extends and connects to the inner side of the air duct portion 120. The lower front end of the second radial support portion 1612 is connected to the inner end of the air outlet frame portion 110. The distance between the two spaced and opposite first radial support portions 1611 is less than the distance between the two spaced and opposite second radial support portions 1612. The two ends of the first axial support plate 162 are respectively connected to the two opposite sides of the two first radial support portions 1611.

[0071] In this embodiment, since the opposing radial support plate 161 includes a first radial support portion 1611 located at the top and relatively close together, and a second radial support portion 1612 located at the bottom and relatively far apart, the radial support plate 161 is not strictly perpendicular to the length direction of the base in its overall shape. However, the first radial support portion 1611 and the second radial support portion 1612 are each perpendicular to the length direction of the air conditioner indoor unit base. A transition portion 1613 is provided between the first radial support portion 1611 and the second radial support portion 1612. The transition portion 1613 is approximately a semi-circular arc plate and is approximately parallel to the axis of the air duct portion 120.

[0072] By making the distance between the first radial support portion 1611 smaller than the distance between the second radial support portion 1612, the overall thickness of the support base 160 (the dimension of the support base 160 in the length direction of the air conditioner indoor unit base changes in a stepped manner) can be made to avoid the support base 160 of a single thickness from maintaining a long distance continuously in the height direction. This makes it easier for the lower mold to be pulled out from under the base during injection molding, improving manufacturing convenience and helping to improve manufacturing quality.

[0073] Figure 6 This is a schematic diagram of the structure of the air conditioner indoor unit base provided in Embodiment 1 of the present invention, viewed from another direction; Figure 7 This is a schematic diagram of the structure of the air conditioner indoor unit base provided in Embodiment 1 of the present invention, viewed from another direction; as shown. Figure 3 , Figure 6 and Figure 7 As shown, preferably, a backwater channel plate 170 is provided on the rear side of the air duct section 120, and the backwater channel plate 170 is connected to the support base 160; the support base also includes a second axial support plate 163, and the backwater channel plate 170 is connected to the lower end of the second axial support plate 163. The second axial support plate 163 extends inward relative to the air duct section 120, and the second axial support plate 163, the two opposing second radial support sections 1612 and the backwater channel plate 170 enclose to form a side mold groove.

[0074] The back water channel plate 170 is located below the rear water channel section 140. Because one end of the second radial support section 1612 in the width direction of the air duct section 120 is relatively sharp—that is, the tip of the second radial support section 1612 in the angled region between the air duct section 120 and the transition section 1613 is relatively sharp—if the space between the two opposing second radial support sections 1612 is directly formed from below by the lower mold, this part of the mold will be relatively sharp, significantly increasing the difficulty of mold manufacturing, and even making it difficult to form. Therefore, the back water channel plate 170 is provided to separate the aforementioned area, allowing the slider forming this area to move along the side along the width direction of the air duct section 120 before demolding, thereby improving processing convenience and processing quality. By allowing the slider to demold in this direction, the slider body forming the relatively sharp area is no longer the free end of the slider, but rather combined with the slider body outside the width direction of the air duct section 120, thus avoiding the formation of a sharp mold body, which also facilitates the smooth forming of the air conditioner indoor unit base.

[0075] Specifically, the second axial support plate 163 cooperates with the back channel plate 170 and the second radial support portion 1612 to divide the space below the air duct portion 120 into an area that can be formed by the lower mold and an area formed by a slider that slides along the width direction of the air duct portion 120. The latter is the side mold groove. The two do not interfere with each other, which facilitates the forming of their respective areas. In addition, the second axial support plate 163 can be used to distribute the force to the back channel plate 170, thereby using the back channel plate 170 to assist in bearing the load of the support base 160, reducing the force directly acting on the air duct portion 120 from the support base 160, and reducing the deformation of the air duct portion 120.

[0076] Figure 8 This is a schematic diagram of the structure of the air conditioner indoor unit base provided in Embodiment 1 of the present invention, viewed from the air outlet frame side; as shown. Figure 2 and Figure 8 As shown, preferably, the support base 160 further includes a third axial support plate 164, and the two ends of the third axial support plate 163 are respectively connected to the two opposite sides of the two second radial support portions 1612; the air outlet frame portion 110 includes an upper air outlet plate 111 and a lower air outlet plate 112, the radial support plate 161 is integrally formed and connected to the upper air outlet plate 111 and the lower air outlet plate 112, and the second axial support plate 163 is connected to the lower air outlet plate 112.

[0077] The upper air outlet plate 111 and the lower air outlet plate 112 are the upper and lower plates of the air outlet of the base, respectively, and can be used to install the vertical and horizontal air sweeping components and / or the horizontal air sweeping components. The radial support plate 161 is integrally formed and connected to the upper air outlet plate 111 and the lower air outlet plate 112, which not only provides support for the upper air outlet plate 111 and the lower air outlet plate 112 at the center position along the length of the air outlet, but also, by utilizing the third axial support plate 164 and the paired radial support plates 161, the airflow generated by the two cross-flow impeller assemblies can be separated as much as possible, significantly reducing the mixing effect of the two air outlets.

[0078] like Figure 8 As shown, preferably, the lower air outlet plate 112 includes a first sub-lower plate 1121 and a second sub-lower plate 1122 arranged along the length direction of the air conditioner indoor unit base 100. The first sub-lower plate 1121 and the second sub-lower plate 1122 are connected by a connecting plate 1123, and a reinforcing rib 1124 is provided on the connecting plate 1123.

[0079] Specifically, the first sub-lower side plate 1121 and the second sub-lower side plate 1122 are connected by a connecting plate 1123, but the rigidity is low. The reinforcing rib 1124 is perpendicular to the connecting plate 1123.

[0080] By setting the reinforcing rib 1124, the rigidity between the first lower sub-side plate 1121 and the second lower sub-side plate 1122 can be effectively improved, thereby improving the overall rigidity of the air outlet frame 110. This location is also where one end of a second axial support plate 163 of the support base 160 is located, which also helps to provide better support for the support base 160.

[0082] Figure 9 This is a schematic diagram of the structure of the air conditioner indoor unit base after installing the cross-flow fan assembly, as provided in Embodiment 2 of the present invention; Figure 10 for Figure 8 A schematic diagram of the structure as viewed from another direction; Figure 11 for Figure 8 The diagram shown is a structural schematic with the pressure cap removed. Figure 12 for Figure 8 The diagram shown is a structural schematic with the first and second wind turbine components omitted. Figure 13 This is a schematic diagram of the connection between the first and second fan assembly of the air conditioner provided in Embodiment 2 of the present invention; as shown. Figures 9-13As shown, Embodiment 2 also provides an air conditioner, including a wall-mounted indoor unit. The wall-mounted indoor unit includes a motor 230, a cross-flow fan assembly, and the air conditioner indoor unit base 100 of Embodiment 1. The cross-flow fan assembly includes a first fan assembly 210 and a second fan assembly 220. The motor 230 is driven to the first fan assembly 210. The first fan assembly 210 and the second fan assembly 220 are coaxially arranged. The end of the first fan assembly 210 connected to the second fan assembly 220 is rotatably mounted on the support base 160.

[0083] Specifically, in this embodiment, the motor 230 is installed at one end of the air duct section 120, so as to... Figure 1 Based on the indicated orientation, it is installed at the right end of the air duct section 120. The motor output shaft 231 extends into the cavity of the air duct section 120, and the motor output shaft 231 can be inserted into the first impeller assembly 210. Figure 1 The first connecting sleeve 211 at the right end, as shown, drives the first wind turbine assembly 210 to rotate. The first wind turbine assembly 210... Figure 1 The left end shown has a first extending shaft 212, which is mounted in the first bearing 250. Specifically, in this embodiment, the extending shaft of the first wind turbine assembly 210 passes through the first bearing 250 and also enters the second wind turbine assembly 220. Figure 13 The second connecting sleeve 221 at the right end, as shown, drives the second wind turbine assembly 220 to rotate. The second wind turbine assembly 220, within its... Figure 13 The left end also has a second protruding shaft 222, which is mounted on the left end of the air duct section 120 via a second bearing 260. In addition, an end plate 246 is provided at the end of the cover 240 in the longitudinal direction to connect with the support base 160 at both ends in the width direction of the air duct section 120.

[0084] By combining the first impeller assembly 210 and the second impeller assembly 220, the length of a single impeller assembly can be reduced. Even if the cross-flow impeller deforms during long-term use, the radial deformation can be minimized. Furthermore, by using the support base 160 to support the connection between the first impeller assembly 210 and the second impeller assembly 220, the overall structure of the two cross-flow impeller assemblies can be constrained approximately at the midpoint of their length during operation, thus improving the operational stability of the cross-flow impeller.

[0085] like Figures 9-12 As shown, preferably, the wall-mounted indoor unit also includes a first bearing 250 and a pressure cover 240. The pressure cover 240 is fixedly connected to the support base 160. The first bearing 250 is installed between the support base 160 and the pressure cover 240. One end of the first fan assembly 210 connected to the second fan assembly 220 is rotatably disposed in the shaft hole of the first bearing 250.

[0086] In this embodiment, the pressure cap 240 is fixedly connected to the upper connecting part 243 of the first axial support plate 162 of the support base 160, so as to cooperate with the lower connecting part 1621 to jointly clamp the first bearing 250.

[0087] By fixing the pressure cap 240 to the support base 160 to clamp the first bearing 250, rotational support can be provided for the first wind turbine assembly 210 and the second wind turbine assembly 220 at their connection points, thereby ensuring the motion stability of the first wind turbine assembly 210 and the second wind turbine assembly 220.

[0088] Figure 14 This is a schematic diagram of the structure of the pressure cap in the air conditioner provided in Embodiment 2 of the present invention, viewed from a slightly lower angle. Figure 15 This is a schematic diagram of the structure of the pressure cap in the air conditioner provided in Embodiment 2 of the present invention, viewed from an obliquely upward angle. Figure 16 This is a cross-sectional view of the pressure cap installed on the support base in an air conditioner according to Embodiment 2 of the present invention. Figures 14-16 As shown, preferably, the pressure cap 240 is provided with a middle upper bearing groove, and the support seat 160 is provided with a middle lower bearing groove. The middle upper bearing groove and the middle lower bearing groove together form a middle bearing cavity for accommodating the first bearing 250.

[0089] Specifically, in this embodiment, a groove is formed in the middle area of ​​the lower surface of the pressure cover 240 to form an upper bearing receiving part 244. The upper bearing receiving part 244 forms a middle upper bearing groove, which cooperates with the middle lower bearing groove of the support seat 160 to form a middle bearing cavity, so as to jointly accommodate and fix the first bearing 250.

[0090] The central bearing cavity is formed by utilizing the upper and lower central bearing grooves, which facilitates processing and manufacturing.

[0091] like Figures 14-16 As shown, preferably, the pressure cap 240 is provided with a threaded connector through hole 245, and the support base 160 is provided with a threaded hole 1622. The threaded connector through hole 245 is used for the threaded connector to pass through and connect with the threaded hole 1622; the pressure cap 240 and the support base 160 are provided with a snap-fit ​​structure that engages with each other.

[0092] Specifically, the pressure cap 240 has an upper connecting portion 243 on its lower surface. Two upper connecting portions 243 are distributed along the width direction of the air duct portion 120 at intervals above the bearing receiving portion 244. A threaded connector through hole 245 can be provided in each of the upper connecting portions 243, corresponding one-to-one with the threaded hole 1622 provided on the support base 160. A threaded connector, such as a screw, is passed through the threaded connector through hole 245 and threadedly connected to the threaded hole 1622, thus fastening the pressure cap 240 to the support base 160. A latch 242 is provided on one of the upper connecting portions 243, corresponding to the slot 1623 provided in the lower connecting portion 1621. Alternatively, in another implementation, the latch 242 can be provided in the lower connecting portion 1621, and the slot 1623 in the upper connecting portion 243. Those skilled in the art can select the positions of the latch 242 and the slot 1623 according to process requirements.

[0093] In addition, each upper connecting part 243 is provided with a radial positioning part 241. Here, the radial positioning part 241 refers to positioning the cover 240 relative to the support base 160 along the radial direction of the cross-flow wind turbine assembly. Specifically, in this embodiment, it can be a radial positioning piece. The two radial positioning pieces are respectively engaged with the outer end faces of the two lower connecting parts 1621 at both ends of the width direction of the air duct 120 along the width direction of the air duct 120, thereby realizing the positioning of the cover 240 relative to the support base 160 in the width direction of the air duct 120.

[0094] By setting the above structure on the cover 240, not only can the cover 240 be fastened to the support base 160, but the cover 240 can also be positioned along the width direction of the air duct 120, thereby ensuring the installation accuracy and stability of the bearings supporting the first wind turbine assembly 210 and the second wind turbine assembly 220, which is conducive to improving the stability of the cross-flow wind turbine operation.
