[0002] An integrated air conditioner is an 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 one biaxial motor inside, which is used to drive the air supply fan on the indoor side and the heat dissipation fan on the outdoor side at the same time. The biaxial 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 on 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 top-mounted method to install and fix the electronic control box on the top of the motor bracket.

[0045] 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

[0046] As Figure 1 shown, the air duct assembly 10 is arranged 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

[0047] As Figure 1 shown, the motor 30 is a double-shaft motor, its outdoor side output shaft 31 is connected to the outdoor fan 40, and is used for driving the outdoor fan 40 to rotate to achieve outdoor side heat dissipation. The indoor side output shaft 32 of the motor 30 is connected to the indoor fan 50 and is used for driving the indoor fan 50 to rotate to achieve indoor side air supply

[0048] In addition, the electric control box 60 is used to adjust the rotation speed of the motor 30 and the working power of the compressor (not shown in the figure) in the integrated air conditioner 1 in a frequency conversion regulation manner. As Figure 1 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

[0049] In this embodiment, as Figures 1 to 7 shown, the motor bracket 11 includes a bottom plate 13. At least one positioning portion 200 extending in the vertical direction is arranged on the bottom plate 13, and the positioning portion 200 is used for fixing the motor bracket 11 on the base 20 when installing the motor bracket 11. At least one vertical hole 300 extending in the vertical direction may also be formed on the bottom plate 13. The vertical hole 300 is configured to install the motor bracket 11 on the base 20 in a manner of vertically inserting a fastener upward. After fixing the motor bracket 11 at the 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 vertically inserting a fastener upward, which is convenient for installation

[0050] Specifically, in some alternative embodiments, the fastener can be a screw. Of course, in other alternative embodiments, the fastener can also be other connection structures

[0051] Further, in some alternative 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. Of course, in some other alternative embodiments, the vertical hole 300 may not be pre-opened on the bottom plate 13, and the vertical hole 300 may be automatically formed by self-tapping screws driven in the vertical direction after entering the bottom plate 13.

[0052] For the air duct assembly 10 of the present utility model, by providing at least one positioning portion 200 extending in the vertical direction on the bottom plate 13 of the motor bracket 11, the motor bracket 11 is fixed on the base 20 when the motor bracket 11 is installed. Also, at least one vertical hole 300 extending in the vertical direction may be formed on the bottom plate 13, facilitating the installation of the motor bracket 11 on the base 20 in a manner of vertically inserting the motor bracket 11 into the fastener. The air duct assembly 10 of the present utility model may form a vertical hole 300 extending in the vertical direction on the bottom plate 13 for the fastener to be inserted 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 other components being provided 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.

[0053] In an alternative embodiment, the vertical hole 300 may be a blind hole, which is formed on the lower surface of the bottom plate 13 with the opening facing vertically downward, so as to facilitate the installation of the motor bracket 11 on the base 20 in a manner of vertically inserting the motor bracket 11 into the fastener.

[0054] In another alternative embodiment, the vertical hole 300 may also be a through hole. As Figures 3 to 5 shown, at least one vertical hole 300 penetrating the bottom plate 13 in the vertical direction may also be formed on the bottom plate 13, so as to facilitate the installation of the motor bracket 11 on the base 20 in a manner of vertically inserting the motor bracket 11 into the fastener. After the motor bracket 11 is fixed at the 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, with convenient installation.

[0055] Correspondingly, at least one vertical installation hole 24 penetrating the base 20 in the vertical direction may also be opened on the base 20. The number of the vertical installation holes 24 is the same as that of the vertical holes 300 on the motor bracket 11, and they are arranged in one-to-one correspondence, so as to facilitate the connection of the motor bracket 11 to the base 20 in a manner of vertically inserting the motor bracket 11 into the fastener. Specifically, the fastener may be inserted into the vertical installation hole 24 and the vertical hole 300 in sequence from bottom to top in the vertical direction to complete the vertical fixation of the motor bracket 11.

[0056] In some embodiments, as Figures 2 to 5As 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.

[0057] 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.

[0058] 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.

[0059] 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.

[0060] 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 the number of mounting portions 100 of the air duct assembly 10 and they are arranged in a one-to-one correspondence. Specifically, during the installation of the motor bracket 11, after the motor bracket 11 is placed on the base 20, each mounting plate 21 is arranged in contact with the mounting portion 100 corresponding thereto for subsequent installation.

[0061] In addition, as Figure 3 shown, lateral mounting holes 22 extending in the left - right horizontal direction can be formed on each mounting plate 21, and the lateral mounting holes 22 are configured to be aligned with the lateral holes 110 after each mounting plate 21 is cooperatively arranged with its corresponding mounting portion 100, so as to mount the motor bracket 11 on the base 20 in such a way that fasteners are inserted into the lateral mounting holes 22 and the lateral holes 110 in the left - right horizontal direction.

[0062] It should be noted that, in some alternative embodiments, the lateral mounting holes 22 extending in the left - right horizontal direction can be pre - formed on the mounting plate 21 for fasteners to be inserted. Of course, in some other alternative embodiments, the lateral mounting holes 22 may not be pre - formed on the mounting plate 21, and the lateral mounting holes 22 are automatically formed by self - tapping screws driven in the left - right horizontal direction after passing through the mounting plate 21.

[0063] In a specific embodiment, as Figure 6 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 - right horizontal sides of the bottom plate 13. The mounting portion 100 has an assembly surface 120 extending vertically, and the lateral holes 110 are vertically formed on the assembly surface 120 so that the lateral holes 110 extend in the left - right horizontal direction.

[0064] 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 - 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 forming the lateral holes 110 on the assembly surface 120, the left - right horizontal extension arrangement of the lateral holes 110 is achieved by using a simple structure. While ensuring that the motor bracket 11 can be laterally fixed and mounted on the base 20, the structural complexity of the mounting structure is reduced, and thus the production cost of the air duct assembly 10 is reduced.

[0065] In some embodiments, 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.

[0066] In some embodiments, the bottom plate 13 may be provided with at least one mounting portion 100 on only one of its left and right lateral sides to provide a fastening force to the motor bracket 11 on one of its left and right lateral sides. Specifically, when the integrated air conditioner 1 is in operation, when viewed from the indoor side toward the outdoor side, the motor 30, the indoor fan 50, and the outdoor fan 40 all rotate clockwise. After the motor 30 is started, especially when the motor 30 is suddenly operated, the motor bracket 11 is subjected to a large torque force, and the motor bracket 11 is deformed by the force. At this time, if Figure 1 As shown, when the motor 30, the indoor fan 50 and the outdoor fan 40 are all rotating in a clockwise direction from the indoor side to the outdoor side, the bottom plate 13 of the motor bracket 11 will first tilt from the left side. Therefore, at least one mounting portion 100 can be arranged on the left side of the left and right lateral sides of the bottom plate 13, and the fixing screws arranged with the base 20 can prevent the bottom plate 13 from tilting due to force, thereby improving the structural stability of the integrated air conditioner 1.

[0067] In some embodiments, the bottom plate 13 may also be provided with at least one mounting portion 100 on each of its left and right lateral sides to provide a fastening force to the motor bracket 11 on both lateral left and right sides, thereby enhancing the mounting strength.

[0068] Specifically, Figures 1 to 7 As shown, a mounting portion 100 can be provided on each of the left and right lateral sides of the base plate 13, thereby ensuring that a fastening force is provided to the motor bracket 11 on both the left and right lateral sides at the same time, reducing the structural complexity, reducing the number of installations, and ensuring installation efficiency.

[0069] In some embodiments, Figure 3 As shown, the orientation of the assembly surfaces 120 on the mounting portions 100 on different sides of the left and right lateral sides of the bottom plate 13 is the same. It should be noted that the orientation of the assembly surface 120 refers to the assembly direction of the fastener when the lateral fastener is inserted into the lateral hole 110 on the assembly surface 120. For example, Figure 3 As shown, when viewed from the indoor side toward the outdoor side, the assembly direction of the fastener is from left to right.

[0070] Therefore, the air duct assembly 10 of the embodiment of the utility model can realize the installation of fasteners into multiple lateral holes 110 from the same lateral direction by setting the assembly surfaces 120 of the mounting parts 100 on different sides of the left and right lateral sides of the base plate 13 in the same direction, thereby improving the installation efficiency.

[0071] In some embodiments, Figures 2 to 7 As shown, the mounting portion 100 is vertically protruded upward from the upper surface of the bottom plate 13. Figures 1 to 3As shown, the mounting plate 21 protrudes vertically upward from the upper surface of the base 20 to be adapted to the mounting portion 100. Specifically, the number of the mounting plates 21 is the same as that of the mounting 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 fits with the fitting surface 120 of the corresponding mounting portion 100 for subsequent installation.

[0072] In this embodiment, since the facing directions of the fitting surfaces 120 of the mounting 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 fit with the corresponding fitting surface 120. Therefore, as Figure 3 shown, a through groove 130 penetrating the bottom plate 13 in the vertical direction can be formed on the bottom plate 13 for the mounting plate 21 to be inserted when installing the motor bracket 11. Specifically, the through groove 130 is located in front of the fitting surface 120 in its facing direction and is used to sleeve 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 fits with the fitting surface 120 for the subsequent lateral installation of the motor bracket 11.

[0073] In some embodiments, as Figure 6 and Figure 7 shown, the projections of 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 to provide fastening forces to the motor bracket 11 on both sides in the front and back directions, thereby further enhancing the installation strength.

[0074] 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 dimension of the mounting portion 100 in the left and right lateral directions is larger than the dimension of the mounting plate 21 in the left and right lateral directions 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 installation strength of the motor bracket 11.

[0075] 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 central 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 back directions, ensuring that the mounting portion 100 can provide sufficient traction force for the fastener in the lateral hole 110, thereby further enhancing the installation strength.

[0076] In some embodiments, asFigure 6 and Figure 7 As shown in Figure 7 , the lateral holes 110 are all 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 a greater traction force for the motor bracket 11, thereby ensuring the structural stability of the integrated air conditioner 1.

[0077] In some embodiments, as Figures 1 to 5 shown in Figures 1 to 5 , 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 be inserted into the positioning hole 23 opened on the base 20 when installing the motor bracket 11, so as to facilitate the fixing of the motor bracket 11 at its preset installation position.

[0078] Correspondingly, as Figures 2 to 5 shown in Figures 2 to 5 , 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.

[0079] For the air duct assembly 10 of the embodiment of the present utility model, by providing at least one positioning portion 200 on the bottom plate 13 of the motor bracket 11 and making the positioning portion 200 protrude vertically downward from the lower surface of the bottom plate 13, so that the positioning portion 200 is inserted into the positioning hole 23 opened on the base 20 when installing the motor bracket 11, pre-positioning of the motor bracket 11 is realized by using the positioning portion 200 and the positioning hole 23. 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 matched with the positioning hole 23 opened on the base 20, realizing the pre-fixing of the motor bracket 11 at its preset installation position by using the matching 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 jamming caused by misalignment of the screw holes, thereby further improving the installation efficiency of the air duct assembly 10.

[0080] In some embodiments, the air duct assembly 10 of the present utility model can 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 in Figure 5 , two positioning portions 200 are spaced in the horizontal left-right direction of the bottom plate 13. Correspondingly, as Figures 2 to 5 shown in Figures 2 to 5 , two positioning holes 23 are spaced in the horizontal left-right direction of the base 20.

[0081] In the air duct assembly 10 of the embodiment of the present utility model, by providing a plurality of positioning parts 200 spaced apart on the bottom plate 13 of the motor bracket 11, the bottom plate 13 can be limited and fixed in the horizontal left - right direction, avoiding the rotation of the motor bracket 11 after positioning, and improving the convenience and accuracy of positioning. In addition, in the air duct assembly 10 of the embodiment of the present utility model, by providing a plurality of positioning parts 200, a plurality of positioning points are formed at different positions of the motor bracket on the bottom plate at intervals, realizing precise positioning, improving the accuracy of positioning, and further reducing the probability of subsequent installation errors, thereby further improving the installation efficiency of the air duct assembly 10.

[0082] In some embodiments, as Figure 5 shown, the positioning part 200 may include a buckle 210. The buckle 210 has a connecting part 211 extending vertically downward from the lower surface of the bottom plate 13 and a hook 212 located at one end of the connecting part 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 a preset installation position.

[0083] In addition, as Figure 5 shown, the positioning part 200 may further include an opening 220 provided around a part of the outer peripheral side of the buckle 210. When installing the motor bracket 11, during the process of inserting the positioning part 200 downward, the position of the positioning hole 23 opened on the base 20 can be confirmed through the opening 220, thereby improving the installation efficiency.

[0084] In some embodiments, as Figure 5 shown, the buckle 210 has a plurality of connecting parts 211 arranged in a ring and circumferentially spaced apart from each other, and each connecting part 211 protrudes radially outward on the outer surface facing away from other connecting parts 211 to form a hook 212. Specifically, the positioning hole 23 may be a circular hole. The outer peripheral surfaces 213 of the hooks 212 of the plurality of connecting parts 211 enclose a conical surface that is larger at the top and smaller at the bottom. The diameter of the positioning hole 23 is larger than the minimum outer diameter L of the conical surface, so as to facilitate the hook 212 to be smoothly inserted into the positioning hole 23, thereby facilitating quick positioning. In addition, the maximum outer diameter H of the conical surface is larger than the diameter of the positioning hole 23, so that the hook 212 is clamped on the lower outer side wall of 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.

[0085] In a specific embodiment, as Figure 7As shown, the buckle 210 has two connecting portions 211 arranged in a circular pattern and circumferentially spaced 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 deformed under pressure, and the gap therebetween is reduced. After the hook 212 is in place, the two connecting portions 211 spring open 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, thus playing a fixing role.

[0086] 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 of the positioning hole 23 in the radial direction, thereby restricting the movement of the motor bracket 11 relative to the base 20 in the vertical direction.

[0087] In the air duct assembly 10 of the embodiment of the present utility model, by setting the positioning portion 200 as the buckle 210 structure, and the shape of the buckle 210 structure can provide a suitable clamping force while being easy to manufacture, which is beneficial to further making the positioning between the motor bracket 11 and the base 20 more 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 the need to first perform 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 achieving pre-positioning, and reduces the production cost.

[0088] In some embodiments, as Figure 3 and Figure 5 shown, the vertical hole 300 can be formed through the bottom plate 13 in the vertical direction, so as to install the motor bracket 11 on the base 20 in a manner of vertically inserting fasteners. After the installation is completed, then drive the following 2 screws. Since it has been pre-positioned, there is no need to re-align the holes, and the installation is convenient.

[0089] Correspondingly, at least one vertical installation hole 24 penetrating the base 20 in the vertical direction can also be provided on the base 20. The number of the vertical installation holes 24 on the base 20 is the same as that of the vertical holes 300 on the motor bracket 11 and they are arranged in one-to-one correspondence, so as to connect the motor bracket 11 to the base 20 in a manner of vertically inserting fasteners. Specifically, the fasteners can be inserted into the vertical installation 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.

[0090] In some embodiments, such 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.

[0091] 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, so as to connect the air guide cover 12 to the housing 70 in a manner of vertically inserting fasteners.

[0092] 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 side hole 110 is located at the position on the side of the air guide cover 12 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 a greater traction force for the motor bracket 11, thereby ensuring the structural stability of the integrated air conditioner 1.

[0093] 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 plate 21 on the base 20 has been evenly fitted with the fitting surface 120 of the corresponding mounting portion 100, the lateral mounting holes 22 thereon are all aligned with the corresponding side 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, 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 fix the motor bracket 11 to the base 20 in a vertically fixed manner. At this time, the fasteners can also be inserted into the lateral mounting holes 22 and the side holes 110 in sequence in the left-right horizontal direction 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.

[0094] 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 the housing 70 can be fixedly connected to the base 20 by using fasteners such as screws. At this time, all the connection holes 71 on the housing 70 are arranged in one-to-one correspondence with all the fixing holes 400 at the top of the air guide cover 12 of the air duct assembly 10. At this time, the fasteners can be sequentially inserted into the connection holes 71 and the fixing holes 400 from top to bottom in the vertical direction, so that the housing 70 and the air guide cover 12 are fixedly connected 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.

[0095] 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, so that while realizing the fastening connection between the components on the air duct assembly 10, the production cost of the air duct assembly 10 is reduced. At the same time, with the above structure, the motor bracket 11 can directly form a fixed connection with the base 20 that combines 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.
