Description

Technical Field

[0001] The utility model relates to the technical field of household appliances, in particular to an air duct assembly for an air conditioner and an integrated air conditioner. Background Art

[0002] An integrated air conditioner is a form of air conditioner with an integrated design of an outdoor unit and an indoor unit, which may include a traditional window air conditioner and a wall hole air conditioner that has emerged in recent years. An integrated air conditioner usually has only a single dual-axis motor inside, which is used to drive both the indoor air supply fan and the outdoor heat dissipation fan at the same time. The dual-axis motor is fixed by a motor bracket, and the motor bracket usually has vertically extending screw holes for screws to be inserted from top to bottom to fix the motor bracket to the base of the integrated air conditioner. There has also appeared a variable-frequency integrated air conditioner in the existing market, which can adjust the rotational speed of the motor and the working power of the compressor in a variable-frequency adjustment manner. And the volume of the electronic control box for variable-frequency adjustment provided in the variable-frequency integrated air conditioner is often larger than that of the electronic control box in the traditional window air conditioner. In order to improve the utilization rate of the internal space of the integrated air conditioner, some existing variable-frequency integrated air conditioners adopt a method of mounting the electronic control box on top to fix the electronic control box on the top of the motor bracket.

[0003] However, when the electronic control box is mounted and fixed on the top of the motor bracket, it blocks the assembly path of the screws inserted into the vertically extending screw holes on the motor bracket from top to bottom, which is not convenient for the motor bracket to be fixed to the base of the air conditioner in a top-down fixing manner, and there are problems such as inconvenient fixing at the top of the motor bracket and low installation efficiency.

[0042] Hereinafter, exemplary embodiments of the present invention will be described in more detail with reference to the accompanying drawings. Although the exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided so that the present disclosure can be more thoroughly understood and the scope of the present invention can be completely conveyed to those skilled in the art.

Figure 3 is Figure 2 A partial enlarged view of part A of the integrated air conditioner shown.

Figure 5 is Figure 4 A partial enlarged view of part B of the integrated air conditioner shown. Figure 6 It is a schematic side view of the air duct assembly according to an embodiment of the present invention. Figure 7 is Figure 6 A partial enlarged view of part C of the air duct assembly shown.

[0044] As Figure 1 shown, the present invention provides an integrated air conditioner 1. The integrated air conditioner 1 of this embodiment generally may include an air duct assembly 10, a base 20, a motor 30, an outdoor fan 40, an indoor fan 50, and an electric control box 60.

[0045] As Figure 1 shown, the air duct assembly 10 is disposed on the base 20, and it includes a motor bracket 11 and a wind guide cover 12. The motor bracket 11 is used for installing the motor 30. The wind guide cover 12 is connected to the motor bracket 11 and is used for installing the outdoor fan 40. That is to say, the air duct assembly 10 can be an outdoor side air duct assembly 10.

[0046] As Figure 1As shown, the motor 30 is a dual-shaft motor, and its outdoor output shaft 31 is connected to the outdoor fan 40, and is used to drive the outdoor fan 40 to rotate to achieve outdoor heat dissipation. The indoor output shaft 32 of the motor 30 is connected to the indoor fan 50, and is used to drive the indoor fan 50 to rotate to achieve indoor air supply.

[0047] In addition, the electric control box 60 is used to adjust the speed of the motor 30 and the working power of the compressor (not shown in the figure) in the integrated air conditioner 1 by frequency conversion regulation. Figure 1 As shown, the electric control box 60 can be arranged on the top of the motor bracket 11 to improve the utilization rate of the internal space of the integrated air conditioner 1.

[0048] In this embodiment, if Figures 2 to 5 As shown, the motor bracket 11 has at least one mounting portion 100. The mounting portion 100 may be formed with a lateral hole 110 extending in the left-right lateral direction, so that the motor bracket 11 can be mounted on the base 20 by inserting a fastener (not shown) laterally. It should be noted that the left-right lateral direction is based on the actual use posture of the integrated air conditioner 1. For example, Figure 1 and Figure 2 As shown in FIG. 1 , the orientation direction from the indoor side to the outdoor side can be set to the front-to-back direction, in which case the left-right lateral direction is perpendicular to the front-to-back direction. Figure 1 and Figure 2 The left and right sides shown are marked only according to the left and right directions when viewed from the indoor side toward the outdoor side.

[0049] Specifically, in some optional embodiments, the fastener can be a screw. Of course, in other optional embodiments, the fastener can also be other connecting structures.

[0050] Furthermore, in some optional embodiments, the mounting portion 100 may be provided with a lateral hole 110 extending in the left-right lateral direction in advance for fasteners to be inserted in. Of course, in other optional embodiments, the mounting portion 100 may not be provided with the lateral hole 110 in advance, and the lateral hole 110 is automatically formed by the self-tapping screws tapped in the left-right lateral direction after entering the mounting portion 100.

[0051] The integrated air conditioner 1 of the embodiment of the utility model is provided with at least one mounting portion 100 on the motor bracket 11 in the air duct assembly 10, and the mounting portion 100 is provided so that a lateral hole 110 extending in the left-right lateral direction can be formed thereon, so that it is convenient to install the motor bracket 11 on the base 20 by inserting a fastener in the side direction. The integrated air conditioner 1 of the embodiment of the utility model is provided with the mounting portion 100 on the motor bracket 11, and the lateral hole 110 extending in the left-right lateral direction can be formed on the mounting portion 100, so that fasteners can be inserted in the left-right lateral direction from the side of the air duct assembly 10, so that the motor bracket 11 is installed on the base 20 in a sideways fixed manner, which solves the problem of inconvenience in installing the motor bracket 11 in a top-fixed manner due to other components being provided on the top of the motor bracket 11, improves the convenience of installing the motor bracket 11, and thus improves the installation efficiency of the air duct assembly 10.

[0052] In some embodiments, Figures 1 to 3 As shown, the base 20 has at least one mounting plate 21 protruding and extending from the base 20 in the vertical direction. Specifically, the number of mounting plates 21 is the same as that of mounting portions 100 and they are arranged in a one-to-one correspondence. Specifically, during the installation process of the motor bracket 11, after the motor bracket 11 is placed on the base 20, each mounting plate 21 is arranged to fit with the mounting portion 100 corresponding thereto for subsequent installation.

[0053] In addition, if Figure 3 As shown, a lateral mounting hole 22 extending along the left-right lateral direction can be formed on each mounting plate 21, and the lateral mounting hole 22 is configured to be opposite to the lateral hole 110 after each mounting plate 21 is matched with its corresponding mounting portion 100, so as to facilitate the motor bracket 11 to be installed on the base 20 in a manner that the fastener is inserted into the lateral mounting hole 22 and the lateral hole 110 along the left-right lateral direction.

[0054] It should be noted that, in some optional embodiments, the mounting plate 21 may be pre-opened with lateral mounting holes 22 extending in the left-right lateral direction for fasteners to be inserted into. Of course, in other optional embodiments, the mounting plate 21 may not be pre-opened with lateral mounting holes 22, and the lateral mounting holes 22 are automatically formed by self-tapping screws tapped in the left-right lateral direction after passing through the mounting plate 21.

[0055] In a specific embodiment, Figures 1 to 7 As shown, the motor bracket 11 includes a bottom plate 13. Specifically, as Figure 6As shown, the bottom plate 13 is in the shape of a horizontally placed flat plate. In addition, the motor bracket 11 further includes a motor support portion 14 vertically extending upward from the middle of the bottom plate 13. The electric control box 60 can be arranged on the top of the motor support portion 14. The mounting portion 100 protrudes and extends vertically from one side of the left and right horizontal sides of the bottom plate 13. The mounting portion 100 has an assembly surface 120 extending vertically, and the lateral hole 110 is vertically opened on the assembly surface 120 so that the lateral hole 110 extends in the left and right horizontal directions.

[0056] In the air duct assembly 10 of the embodiment of the present utility model, by arranging the mounting portion 100 to protrude and extend vertically from one side of the left and right horizontal sides of the bottom plate 13 of the motor bracket 11, arranging an assembly surface 120 extending vertically on the mounting portion 100, and vertically opening the lateral hole 110 on the assembly surface 120, the left and right horizontal extension setting of the lateral hole 110 can be completed by using a simple structure. While ensuring that the motor bracket 11 can be laterally fixed and installed on the base 20, the structural complexity of the installation structure is reduced, and thus the production cost of the air duct assembly 10 is reduced.

[0057] In some embodiments, such as Figure 3 and Figure 5 shown, the mounting plate 21 on the base 20 can be formed by cutting and bending upward the plate surface of the base 20, thereby reducing the production cost and production efficiency of the base 20.

[0058] In some embodiments, at least one mounting portion 100 can be provided only on one side of the left and right horizontal sides of the bottom plate 13 to provide a fastening force to the motor bracket 11 on one side of the left and right horizontal sides. Specifically, when the integrated air conditioner 1 is operating, from the perspective of observing from the indoor side towards the outdoor side, the motor 30, the indoor fan 50, and the outdoor fan 40 all rotate clockwise. After the motor 30 starts, especially when the motor 30 suddenly operates, the torque received by the motor bracket 11 is relatively large, and the motor bracket 11 deforms under force. At this time, as Figure 1 shown, when the motor 30, the indoor fan 50, and the outdoor fan 40 all rotate in the clockwise direction within the perspective of observing from the indoor side towards the outdoor side, the bottom plate 13 of the motor bracket 11 will first tilt up from the left side. Thus, at least one mounting portion 100 can be provided on the left side of the left and right horizontal sides of the bottom plate 13 to prevent the bottom plate 13 from tilting up under force by setting fixing screws with the base 20, thereby improving the structural stability of the integrated air conditioner 1.

[0059] In some embodiments, at least one mounting portion 100 can also be provided on each side of the left and right horizontal sides of the bottom plate 13 to provide a fastening force to the motor bracket 11 on both the left and right horizontal sides simultaneously, thereby enhancing the installation strength.

[0060] Specifically, as Figures 1 to 7 shown, each of the left and right lateral sides of the bottom plate 13 may be respectively provided with an installation portion 100, thereby ensuring that while providing fastening forces to the motor bracket 11 on both the left and right lateral sides simultaneously, the structural complexity is reduced, the number of installations is decreased, and the installation efficiency is ensured.

[0061] In some embodiments, as Figure 3 shown, the facing directions of the fitting surfaces 120 on the installation portions 100 on different sides of the left and right lateral sides of the bottom plate 13 are the same. It should be noted that the facing direction of the fitting surface 120 refers to the fitting direction of the fastener when using a lateral fastener to insert into the lateral hole 110 on the fitting surface 120. For example, as Figure 3 shown, from the perspective of observing from the indoor side towards the outdoor side, the fitting direction of the fastener is from left to right.

[0062] Thus, for the air duct assembly 10 of the embodiment of the present utility model, by setting the facing directions of the fitting surfaces 120 on the installation portions 100 on different sides of the left and right lateral sides of the bottom plate 13 to be the same, it is possible to load fasteners into a plurality of lateral holes 110 from the same lateral direction, thereby improving the installation efficiency.

[0063] In some embodiments, as Figures 2 to 7 shown, the installation portion 100 protrudes vertically upward from the upper surface of the bottom plate 13. Correspondingly, as Figures 1 to 3 shown, the mounting plate 21 protrudes vertically upward from the upper surface of the base 20 to be adapted to the installation portion 100. Specifically, the number of the mounting plates 21 is the same as that of the installation portions 100 and they are arranged in one-to-one correspondence. During the installation of the motor bracket 11, after the motor bracket 11 is placed on the base 20, each mounting plate 21 protrudes from the bottom plate 13 in the vertical direction and abuts against the fitting surface 120 of the corresponding installation portion 100 for subsequent installation.

[0064] In this embodiment, since the facing directions of the fitting surfaces 120 on the installation portions 100 on different sides of the left and right lateral sides of the bottom plate 13 are the same, at least one mounting plate 21 on the base 20 needs to penetrate through the bottom plate 13 to abut against the corresponding fitting surface 120. Therefore, as Figure 3 shown, a through slot 130 penetrating the bottom plate 13 in the vertical direction may be formed on the bottom plate 13 for the mounting plate 21 to be inserted when installing the motor bracket 11. Specifically, the through slot 130 is located in front of the fitting surface 120 in its facing direction, and is used to sleeve on the mounting plate 21 corresponding to the lateral hole 110 on the base 20 when installing the motor bracket 11, so that the mounting plate 21 abuts against the fitting surface 120 for subsequent lateral installation of the motor bracket 11.

[0065] In some embodiments, asFigure 6 and Figure 7 As shown in Figure 7 , the mounting portions 100 on different sides of the left and right lateral sides of the bottom plate 13 are at least partially staggered in the left and right lateral directions, so as to provide a fastening force to the motor bracket 11 on both sides in the front and rear directions, thereby further enhancing the mounting strength.

[0066] In some embodiments, as Figure 3 shown, the mounting portion 100 can be a trapezoidal plate that is wider at the bottom and narrower at the top, and both top corners are chamfered. The size of the mounting portion 100 in the left and right lateral directions is greater than the size of the mounting plate 21 in the left and right lateral directions, so as to ensure that the assembly depth of the fastener in the lateral hole 110 can provide sufficient fastening force for the motor bracket 11, thereby enhancing the mounting strength of the motor bracket 11.

[0067] Furthermore, the projection of the mounting portion 100 in the left and right lateral directions can be an isosceles trapezoid. Specifically, as Figure 6 shown, the projection of the mounting portion 100 in the left and right lateral directions can be an isosceles trapezoid with chamfered top corners. Based on this, the axis of the projection of the lateral hole 110 in the left and right lateral directions is located on the axis of the isosceles trapezoid. That is to say, the lateral hole 110 is arranged in the middle of the mounting portion 100 in the front and rear directions, ensuring that the mounting portion 100 can provide sufficient traction force for the fastener in the lateral hole 110, thereby further enhancing the mounting strength.

[0068] In some embodiments, as Figure 6 and Figure 7 shown, the lateral holes 110 are both located at the position close to the motor bracket 11 between the air guide cover 12 and the motor bracket 11, so as to laterally fix the middle part of the air duct assembly 10 and provide greater traction force for the motor bracket 11, thereby ensuring the structural stability of the integrated air conditioner 1.

[0069] In some embodiments, as Figures 1 to 5 shown, the motor bracket 11 further has at least one positioning portion 200 provided on the bottom plate 13. The positioning portion 200 protrudes vertically downward from the lower surface of the bottom plate 13. The lower surface of the bottom plate 13 is the surface of the bottom plate 13 away from the motor support portion 14. The positioning portion 200 is used to insert into the positioning hole 23 opened on the base 20 when the motor bracket 11 is installed, so as to facilitate the fixing of the motor bracket 11 at its preset installation position.

[0070] Correspondingly, as Figures 2 to 5 shown, at least one positioning hole 23 penetrating the base 20 in the vertical direction is opened on the base 20. The number of the positioning holes 23 is the same as that of the positioning portions 200 on the motor bracket 11, and they are arranged in one-to-one correspondence, so as to connect the motor bracket 11 with the base 20 by vertically inserting the positioning portion 200 into the positioning hole 23.

[0071] For the air duct assembly 10 according to an embodiment of the present utility model, at least one positioning portion 200 provided on the bottom plate 13 of the motor bracket 11 is arranged such that the positioning portion 200 protrudes vertically downward from the lower surface of the bottom plate 13, so that when the motor bracket 11 is installed, the positioning portion 200 is inserted into the positioning hole 23 formed on the base 20, thereby realizing pre-positioning of the motor bracket 11 by using the positioning portion 200 and the positioning hole 23 when installing the motor bracket 11. The air duct assembly 10 of the present utility model is provided with a positioning portion 200 on the motor bracket 11 that can be cooperatively arranged with the positioning hole 23 formed on the base 20, realizing pre-fixing of the motor bracket 11 at its preset installation position by using the cooperation relationship between the positioning portion 200 and the positioning hole 23, eliminating the installation step of aligning the screw holes, improving the positioning speed, and avoiding the problem of screw thread jamming caused by misalignment of the screw holes, thereby further improving the installation efficiency of the air duct assembly 10.

[0072] In some embodiments, the air duct assembly 10 of the present utility model may be provided with a plurality of spaced positioning portions 200 on the bottom plate 13 of the motor bracket 11. Specifically, as Figure 4 and Figure 5 shown, two positioning portions 200 are spaced in the left-right horizontal direction of the bottom plate 13. Correspondingly, as Figures 2 to 5 shown, two positioning holes 23 are spaced in the left-right horizontal direction of the base 20.

[0073] For the air duct assembly 10 according to an embodiment of the present utility model, by providing a plurality of spaced positioning portions 200 on the bottom plate 13 of the motor bracket 11, the bottom plate 13 can be limited and fixed in the left-right horizontal direction, avoiding rotation of the motor bracket 11 after positioning, and improving the convenience and accuracy of positioning.

[0074] In some embodiments, as Figure 5 shown, the positioning portion 200 may include a buckle 210. The buckle 210 has a connecting portion 211 extending vertically downward from the lower surface of the bottom plate 13 and a hook 212 located at one end of the connecting portion 211 away from the bottom plate 13. The hook 212 is used to be clamped with the outer peripheral side wall of the positioning hole 23 after being inserted and completely passing through the positioning hole 23 to fix the motor bracket 11 at the preset installation position.

[0075] In addition, as Figure 5 shown, the positioning portion 200 may further include an opening 220 provided around a part of the outer periphery of the buckle 210. When installing the motor bracket 11, during the process of inserting the positioning portion 200 downward, the position of the positioning hole 23 formed on the base 20 can be confirmed through the opening 220, thereby improving the installation efficiency.

[0076] In some embodiments, as Figure 5As shown in the figure, the buckle 210 has a plurality of connecting portions 211 arranged in a circular array and circumferentially spaced apart from each other, and each connecting portion 211 forms a hook 212 that protrudes radially outward on the outer surface facing away from the other connecting portions 211. Specifically, the positioning hole 23 can be a circular hole. The outer peripheral surfaces 213 of the hooks 212 of the plurality of connecting portions 211 enclose a conical surface that is larger at the top and smaller at the bottom. The diameter of the positioning hole 23 is greater than the minimum outer diameter L of the conical surface, so as to facilitate the smooth insertion of the hook 212 into the positioning hole 23, thereby facilitating quick positioning. In addition, the maximum outer diameter H of the conical surface is greater than the diameter of the positioning hole 23, so that the hook 212 is stuck on the outer side wall below the positioning hole 23 after being completely inserted into the positioning hole 23, thereby restricting the movement of the motor bracket 11 in the vertical direction after being positioned at the preset installation position, thereby improving the installation efficiency.

[0077] In a specific embodiment, as Figure 7 shown, the buckle 210 has two connecting portions 211 arranged in a circular array and circumferentially spaced apart from each other. The hooks 212 at the front ends of the two connecting portions 211 are both semi-conical, and the maximum outer diameter H of the cone is greater than the diameter of the positioning hole 23. There is a gap of 2-6 mm between the two connecting portions 211. For example, the gap width can be 4 mm. When the hook 212 is inserted into the positioning hole 23, the two connecting portions 211 are compressed and deformed, and the gap therebetween is reduced. After the hook 212 is in place, the two connecting portions 211 bounce back under the action of the elastic force generated by the deformation, and the gap therebetween returns to the initial width. At this time, since the maximum diameter of the cone is greater than the diameter of the positioning hole 23, the hook 212 can be stuck on the base 20 at the positioning hole 23, thereby playing a fixing role.

[0078] In this embodiment, the buckle 210 is configured such that the gap between the connecting portions 211 is reduced during the process of inserting the hook 212 into the positioning hole 23, and the connecting portions 211 are reset after the hook 212 completely passes through the positioning hole 23 so that the hook 212 reaches the outside in the radial direction of the positioning hole 23, so as to restrict the movement of the motor bracket 11 in the vertical direction relative to the base 20.

[0079] In the air duct assembly 10 of the embodiment of the present invention, by setting the positioning portion 200 into the buckle 210 structure, and the shape of the buckle 210 structure is convenient for manufacturing while being able to provide an appropriate clamping force, which is beneficial to further making the positioning between the motor bracket 11 and the base 20 reliable. Using the above structure, when installing the motor bracket 11 in the air duct assembly 10 of this embodiment, pre-positioning can be performed by means of the buckle 210 structure, without first performing the operation of aligning the screw holes, which is simple and easy, simplifies the operation complexity, and improves the production efficiency. At the same time, the cooperation structure of the buckle 210 and the positioning hole 23 reduces the number of fasteners used while realizing pre-positioning, and reduces the production cost.

[0080] In some embodiments, at least one vertical hole 300 extending in the vertical direction may be formed on the bottom plate 13. The vertical hole 300 is configured to install the motor bracket 11 on the base 20 by inserting a fastener vertically upward. After the motor bracket 11 is fixed at a preset installation position via the positioning portion 200, there is no need to re-align the holes, and the motor bracket 11 can be directly installed on the base 20 by inserting the fastener vertically upward, which is convenient for installation.

[0081] In an optional embodiment, the vertical hole 300 may be a blind hole formed on the lower surface of the bottom plate 13 with an opening facing vertically downward, so as to facilitate mounting the motor bracket 11 on the base 20 by vertically inserting a fastener.

[0082] In another optional embodiment, the vertical hole 300 may also be a through hole. Figures 3 to 5 As shown, at least one vertical hole 300 penetrating the bottom plate 13 in the vertical direction may be formed on the bottom plate 13, so as to facilitate the motor bracket 11 to be installed on the base 20 by vertically inserting fasteners. After the motor bracket 11 is fixed at the preset installation position via the positioning portion 200, there is no need to realign the holes, and the motor bracket 11 can be directly installed on the base 20 by vertically inserting fasteners upward, which is convenient for installation.

[0083] Correspondingly, at least one vertical mounting hole 24 penetrating the base 20 in the vertical direction may be provided on the base 20. The number of the vertical mounting holes 24 is the same as the number of the vertical holes 300 on the motor bracket 11, and they are arranged in a one-to-one correspondence, so that the motor bracket 11 can be connected to the base 20 by vertically inserting fasteners. Specifically, the fasteners can be inserted into the vertical mounting holes 24 and the vertical holes 300 in sequence from bottom to top in the vertical direction to complete the vertical fixation of the motor bracket 11.

[0084] Furthermore, in some optional embodiments, at least one vertical hole 300 extending in the vertical direction may be pre-opened on the bottom plate 13 for fasteners to be inserted into. Of course, in other optional embodiments, the bottom plate 13 may not be pre-opened with the vertical hole 300, and the vertical hole 300 may be automatically formed by the self-tapping screws tapped in the vertical direction after entering the bottom plate 13.

[0085] The air duct assembly 10 of the present utility model realizes the fixation of the motor bracket 11 on the base 20 when installing the motor bracket 11 by providing at least one positioning portion 200 extending in the vertical direction on the bottom plate 13 of the motor bracket 11. It also facilitates the installation of the motor bracket 11 on the base 20 in a manner of vertically inserting the motor bracket 11 upward into the fastener by forming at least one vertical hole 300 extending in the vertical direction on the bottom plate 13. The air duct assembly 10 of the present utility model can form a vertical hole 300 extending in the vertical direction on the bottom plate 13 for loading the fastener from the bottom surface of the air duct assembly 10 from bottom to top, so as to install the motor bracket 11 on the base 20 in a bottom-to-top fixing manner, solving the problem that it is inconvenient to install the motor bracket 11 in a top-to-bottom fixing manner due to the presence of other components at the top of the motor bracket 11, improving the installation convenience of the motor bracket 11, and thus improving the installation efficiency of the air duct assembly 10.

[0086] In some embodiments, as Figure 5 shown, the integrated air conditioner 1 further includes a housing 70. The housing 70 covers the upper part of the air duct assembly 10 and is detachably connected to the base 20. As Figure 1 shown, the air guide cover 12 covers the outside of the outdoor fan 40. Specifically, as Figure 1 and Figure 2 shown, at least one fixing hole 400 extending in the vertical direction can be formed at the top of the air guide cover 12.

[0087] Correspondingly, at least one connecting hole 71 extending in the vertical direction can be formed at the position of the top of the housing 70 corresponding to the fixing hole 400. The number of the connecting holes 71 is the same as that of the fixing holes 400 and they are arranged in one-to-one correspondence to facilitate the connection of the air guide cover 12 to the housing 70 in a manner of vertically inserting the fastener.

[0088] Specifically, the air guide cover 12 can be integrally formed with the motor bracket 11, thereby enhancing the structural stability of the integrated air conditioner 1. Thus, the lateral hole 110 is located at a position close to the motor bracket 11 between the air guide cover 12 and the motor bracket 11 to laterally fix the middle part of the air duct assembly 10 and provide a greater traction force for the motor bracket 11, thereby ensuring the structural stability of the integrated air conditioner 1.

[0089] When installing the air duct assembly 10, first place the motor bracket 11 on the base 20 of the integrated air conditioner 1 from top to bottom, and insert the positioning portion 200 into the positioning hole 23 to complete the pre-positioning of the motor bracket 11. After the motor bracket 11 reaches the pre-positioning position, the mounting plates 21 on the base 20 are all in contact with the mating surfaces 120 of the corresponding mounting portions 100, the lateral mounting holes 22 thereon are all aligned with the corresponding lateral holes 110, and the vertical holes 300 on the motor bracket 11 are also all aligned with the corresponding vertical mounting holes 24. At this time, fasteners can be inserted successively from bottom to top in the vertical direction into the vertical mounting holes 24 and the vertical holes 300 to fix the motor bracket 11 to the base 20 in a vertically fixed manner. At this time, fasteners can also be inserted successively in the left-right horizontal direction into the lateral mounting holes 22 and the lateral holes 110 to fix the motor bracket 11 to the base 20 in a laterally fixed manner. Thus, the assembly between the motor bracket 11 and the base 20 is completed.

[0090] After the installation of other components inside the integrated air conditioner 1 is completed, the housing 70 can be sleeved over the air duct assembly 10 from top to bottom. The lower end of the housing 70 can be inserted into the upper end of the base 20, and fasteners such as screws can be used to fixedly connect the housing 70 to the base 20. At this time, all the connection holes 71 on the housing 70 are exactly aligned with all the fixing holes 400 at the top of the air guide cover 12 of the air duct assembly 10. At this time, fasteners can be inserted successively from top to bottom in the vertical direction into the connection holes 71 and the fixing holes 400 to fixedly connect the housing 70 and the air guide cover 12 in a vertically fixed manner. Thus, the assembly between the air duct assembly 10 and the base 20 and the housing 70 of the integrated air conditioner 1 is completed.

[0091] In this embodiment, the air duct assembly 10 can be integrally formed. That is to say, the motor bracket 11 and the air guide cover 12 are integrally formed, thereby while realizing the fastening connection between the components on the air duct assembly 10, reducing the production cost of the air duct assembly 10. At the same time, using the above structure, the motor bracket 11 can directly form a fixed connection with the base 20 combining vertical fixation and lateral fixation, and can form a fixed connection with the housing 70 via the air guide cover 12, thereby realizing the stable installation of the motor bracket 11 and improving the overall installation strength of the air duct assembly 10.
