Description

Technical Field

[0001] This application relates to the field of household appliance technology, and more particularly to a ducted air conditioner. Background Technology

[0002] Ductless air conditioners, also known as ducted units, are air conditioning devices that use a duct system for air supply and return. They are typically installed within the ceiling, using a concealed installation method that saves indoor space, enhances the overall aesthetics, and is suitable for both residential and commercial spaces. Ductless air conditioners also achieve uniform indoor temperature distribution through a well-designed air duct system, providing a comfortable living environment.

[0003] Because ducted air conditioners are concealed within the ceiling, maintenance is mostly performed through the return air vents, which limits space. The common technology uses clips and screws to secure the chassis sheet metal. While this mechanism meets the stability requirements to some extent, it reveals significant limitations during after-sales repair and disassembly / reassembly. Specifically, the extremely limited maintenance space, coupled with the tightness of the clips and screws, makes chassis disassembly and reassembly exceptionally cumbersome, time-consuming, and often requires substantial manpower to remove the base plate for in-depth repair work.

[0004] Therefore, the base plate of the existing duct air conditioner is inconvenient to disassemble and assemble, and needs further improvement. Utility Model Content

[0005] In view of this, the purpose of this application is to provide a ducted air conditioner.

[0006] The technical solution adopted in this application to solve the above-mentioned technical problems is as follows:

[0016] Optionally, in some embodiments of the present application, when the second bottom plate opens the maintenance opening, the first connecting portion and the second connecting portion are hooked.

[0017] Optionally, in some embodiments of the present application, when the second bottom plate opens the maintenance opening, the connection between the first flat plate and the first side wall abuts against the third side wall, and the end of the second side wall abuts against the connection between the fifth side wall and the sixth side wall to fix the second bottom plate.

[0018] Optionally, in some embodiments of the present application, any one of the housing and the second bottom plate is provided with a buckle, and the other is provided with a slot. When the second bottom plate closes the maintenance opening, the buckle and the slot are engaged to fix the second bottom plate.

Any embodiment described as exemplary in this application is not necessarily to be construed as being more preferred or advantageous than other embodiments. The following description is provided to enable any person skilled in the art to make and use this application. Details are set forth in the following description for purposes of explanation. It should be understood that those skilled in the art will recognize that this application can be made without using these specific details. In other instances, known structures and processes are not described in detail to avoid obscuring the description of this application with unnecessary detail. Therefore, this application is not intended to be limited to the embodiments shown, but is consistent with the broadest scope of the principles disclosed in this application.

[0046] To facilitate understanding of the present application, the spline curves and arrows used in the reference numerals in the accompanying drawings are explained below: spline curves without arrows indicate solid parts, that is, parts with solid structures; spline curves with arrows indicate virtual parts, that is, parts without solid structures.

[0047] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 This application provides a ducted air conditioner 100.

[0048] Please refer to the following for details. Figure 1 The ducted air conditioner 100 includes a housing 10 and a first base plate 20. The first base plate 20 and the housing 10 together define a receiving cavity 11 and a maintenance port 12. The housing 10 and the first base plate 20 can be connected in a manner known in the art, such as snap-fit ​​or screw-fit.

[0049] In some embodiments of this application, the ducted air conditioner 100 further includes a partition 14 located within the receiving cavity 11, which divides the receiving cavity 11 into a first cavity 111 and a second cavity 112. A heat exchanger 15 is disposed in the first cavity 111, and a centrifugal fan assembly 16 is disposed in the second cavity 112. A maintenance port 12 is located in the second cavity 112. It is understood that the heat exchanger 15 can achieve cooling or heating functions through heat exchange, thereby regulating the temperature; the centrifugal fan assembly 16 can ensure efficient heat exchange through air circulation.

[0050] It should be noted that other components known in the art may also be provided in the first cavity 111 and the second cavity 112. For example, a water receiving tray 17 may also be provided in the first cavity. The water receiving tray 17 is located below the heat exchanger 15 and is used to collect and discharge the condensate generated by the heat exchanger 15 during heat exchange.

[0051] Please see Figure 5 Furthermore, the housing 10 also includes an air inlet and an air outlet. The air inlet can be located on the side of the second cavity 112 opposite to the first cavity 111, and the air outlet can be located on the side of the first cavity 111 opposite to the second cavity 112. Specifically, the centrifugal fan assembly 16 draws indoor air into the second cavity 112 through the air inlet and delivers it to the first cavity 111. The heat exchanger 15 exchanges heat with the air entering the first cavity 111 and then blows it into the room through the air outlet. The heat exchanger 15 and the centrifugal fan assembly 16 work together to achieve the temperature regulation and air circulation functions of the air conditioner.

[0052] Please see Figure 6 In some embodiments of this application, the centrifugal fan assembly 16 includes a centrifugal fan 161 and a motor 162 located between adjacent centrifugal fans 161. The motor 162 is used to provide a power source to drive the centrifugal fan 161 to operate.

[0053] In some embodiments of this application, the centrifugal fan 161 includes a volute structure 1611 and centrifugal fan blades 1612 located within the volute structure 1611. The volute structure 1611 includes a first volute 1611a and a second volute 1611b connected together. Driven by a motor 162, the centrifugal fan blades 1612 apply centrifugal force to the passing gas, thereby effectively conveying the gas radially and improving aerodynamic efficiency. The volute structure 1611, through specific design and structure, allows the gas to flow along the profile of the volute into the first cavity 111 for heat exchange. The volute structure 1611 also reduces the noise generated by gas vortices and turbulence caused by the rotation of the centrifugal fan blades 1612.

[0054] When the centrifugal fan assembly 16 malfunctions and needs repair or replacement, the second volute 1611b, centrifugal fan blades 1612 and motor 162 can be removed through the maintenance port 12 or installed in the receiving cavity 11.

[0055] In some embodiments of this application, please refer to Figure 7 , Figure 8 , Figure 9 , Figure 10 and Figure 11 The first base plate 20 includes a first flat plate 21 and a first connecting portion 22 located on the side of the first flat plate 21 near the maintenance port 12. The first connecting portion 22 and the first flat plate 21 are bent together, defining a first movable groove 223 with an opening facing away from the maintenance port 12.

[0056] The ducted air conditioner 100 also includes a second base plate 30. The second base plate 30 is located at the service port 12. The second base plate 30 includes a second flat plate 31 and a second connecting portion 32 located on the side of the second flat plate 31 near the first base plate 20. The second connecting portion 32 and the first flat plate 21 are bent and connected to define a second movable groove 325 with an opening facing the service port 12.

[0057] The first connecting part 22 and the second connecting part 32 are connected in the receiving cavity 11, so that the second base plate 30 rotates around the connection between the first connecting part 22 and the second connecting part 32 to open or close the maintenance port 12.

[0058] It can be understood that the first base plate 20 is a base plate structure near the air outlet, which together with the housing 10 defines the first cavity 111, and the second base plate 30 is a base plate structure near the air inlet, which together with the housing 10 defines the second cavity 112.

[0059] It should be noted that both the first base plate 20 and the second base plate 30 are located at the bottom of the housing 10. Here, "bottom" refers to the relative position of the duct air conditioner 100 when it is installed in the ceiling.

[0060] The duct-type air conditioner 100 provided in this application embodiment has the first movable slot 223 and the second movable slot 325 having opposite openings. They can be overlapped to allow the second base plate 30 to rotate and open the maintenance port 12 when cleaning or maintenance is required on components such as the centrifugal fan 161 and the motor 162 in the receiving cavity 11. After opening to a preset angle, the second connecting part 32 overlaps and is fixed with the first connecting part 22. This eliminates the need to completely remove the second base plate 30 for cumbersome operations and eliminates the need for manual lifting of the second base plate 30, thus eliminating the safety hazard of the second base plate 30 slipping. After cleaning or maintenance is completed, the second base plate 30 can be closed by simply rotating it in the opposite direction. The operation is simple and convenient, improving cleaning and maintenance efficiency and reducing safety risks.

[0061] Please refer to the specific embodiments described in this application. Figure 8 , Figure 9 , Figure 10 and Figure 11 The first connecting portion 22 includes a first side wall 221 and a second side wall 222 that are bent and connected, and the first side wall 221 and the second side wall 222 define a first movable slot 223.

[0062] In some embodiments of the present application, the second connecting portion 32 includes a third side wall 321, a fourth side wall 322, a fifth side wall 323, and a sixth side wall 324 that are sequentially bent and connected, and the third side wall 321, the fourth side wall 322, the fifth side wall 323, and the sixth side wall 324 define a second movable slot 325.

[0063] Wherein, when the second bottom plate 30 closes the maintenance opening 12, the first side wall 221, the third side wall 321, and the fifth side wall 323 are arranged in parallel, and the second side wall 222, the fourth side wall 322, and the sixth side wall 324 are arranged in parallel.

[0064] It should be noted that when the second bottom plate 30 closes the maintenance opening 12, the second side wall 222 is located in the second movable slot 325, and the sixth side wall 324 is located in the first movable slot 223. In this way, it is convenient for the first connecting portion 22 and the second connecting portion 32 to overlap and realize the rotation of the second bottom plate 30.

[0065] Furthermore, the first flat plate 21, the first side wall 221, and the second side wall 222 are in a "C" shape with the opening facing away from the maintenance opening 12. The fourth side wall 322, the fifth side wall 323, and the sixth side wall 324 are in a "C" shape with the opening facing the maintenance opening 12. The first connecting portion 22 and the second connecting portion 32 are inserted and matched with each other. In other words, the first side wall 221 is perpendicular to the first flat plate 21, and the second side wall 222 is perpendicular to the first side wall 221. Correspondingly, the fifth side wall 323 is perpendicular to the fourth side wall 322, and the sixth side wall 324 is perpendicular to the fifth side wall 323.

[0066] In some embodiments of the present application, the length of the second side wall 222 is less than the length of the fourth side wall 322, and the sum of the length of the second side wall 222 and the length of the sixth side wall 324 is greater than the fourth side wall 322. It should be noted that the "length" here refers to the length in the direction from the first bottom plate 20 to the second bottom plate 30. In this way, when the second bottom plate 30 rotates, a rotational movement space for flowing out of the second connecting portion 32 can be provided, avoiding the mutual abutment of the side walls of the first connecting portion 22 and the second connecting portion 32 from affecting the rotation of the second bottom plate 30, and at the same time avoiding the situation that the gap between the first connecting portion 22 and the second connecting portion 32 is too large, resulting in the second bottom plate 30 falling off during the rotation process, and ensuring the stability of the rotation process of the second bottom plate 30.

[0067] In some embodiments of this application, when the maintenance opening 12 is closed on the second base plate 30, the first plate 21 and the second plate 31 are located on the same plane, and the second side wall 222 and the fourth side wall 322 are fitted together. More specifically, the fourth side wall 322 is located above the second side wall 222. The first plate 21 and the second plate 31 are assembled as a planar pair, and their positions in terms of height can be kept uniform, improving the flatness and aesthetics of the bottom structure of the duct air conditioner 100.

[0068] Please refer to it again. Figure 11 In some embodiments of this application, when the maintenance port 12 is opened on the second base plate 30, the first connecting portion 22 and the second connecting portion 32 hook together. It should be noted that hooking involves bending the ends of two objects into inward-facing hook shapes, interlocking them, and thus achieving docking. Hooking requires no additional tools, is easy to use, and ensures even force distribution at the docking points, thereby improving the connection stability between the second base plate 30 and the first base plate 20 when the maintenance port 12 is opened.

[0069] Specifically, when the maintenance port 12 is opened on the second base plate 30, the connection between the first flat plate 21 and the first side wall 221 abuts against the third side wall 321, and the end of the second side wall 222 abuts against the connection between the fifth side wall 323 and the sixth side wall 324 to fix the second base plate 30. This fixes the second base plate 30 in a preset position, facilitating operation by maintenance personnel, preventing the second base plate 30 from falling off, reducing safety risks, and eliminating safety hazards. It should be noted that the maximum rotation angle of the second base plate 30 can be adjusted by changing the dimensional relationship between the first side wall 221, the second side wall 222, the third side wall 321, the fourth side wall 322, the fifth side wall 323, and the sixth side wall 324, thereby changing the stress point when the second base plate 30 rotates.

[0070] Please see Figure 2 , Figure 12 , Figure 13 and Figure 14 In some embodiments of this application, either the housing 10 or the second base plate 30 is provided with a buckle 33, and the other is provided with a slot 13. When the maintenance port 12 of the second base plate 30 is closed, the buckle 33 and the slot 13 engage to fix the second base plate 30.

[0071] Provided in this application Figure 12 , Figure 13 and Figure 14Taking a housing 10 with a slot 13 and a second base plate 30 with a buckle 33 as an example, the housing 10 has a slot 13 on the side near the second base plate 30, and the second base plate 30 has a buckle 33 on the side near the housing 10. The buckle 33 and the slot 13 are positioned correspondingly. When the second base plate 30 is rotated to close the maintenance port 12, the buckle 33 engages with the slot 13, fixing the second base plate 30 and preventing it from falling off. It should be noted that there can be multiple buckles 33 and slots 13.

[0072] Please see Figure 8 and Figure 10 In some embodiments of this application, the end of the second plate 31 furthest from the second connecting portion 32 is further provided with a fixing portion 34 for fixed connection with the side of the housing 10 where the return air vent is provided. It is understood that the fixing portion 34 can further improve the stability of the second base plate 30 fixed to the housing 10 when the maintenance port 12 is closed. The fixing portion 34 can be connected to the side of the housing 10 where the return air vent is provided by screws.

[0073] This solution achieves the rotation of the second base plate 30 to open or close the maintenance port 12 through the cooperation of the first side wall 221 and the second side wall 222 of the first connecting part 22 with the third side wall 321, the fourth side wall 322, the fifth side wall 323 and the sixth side wall 324 of the second connecting part 32. It has a simple structure, is easy to operate and has high safety.

[0074] Please refer to it again. Figure 1 , Figure 2 , Figure 3 and Figure 4 The specific rotation process of the second base plate 30 is as follows:

[0075] When it is necessary to open the maintenance port 12 to clean, repair, or replace the centrifugal fan assembly 16, unscrew the screws on the side of the housing 10 where the return air inlet is located on the fixing part 34, push the second base plate 30 towards the air inlet, so that the buckle 33 on the second base plate 30 disengages from the slot 13 on the housing 10, and the second connecting part 32 contacts the end of the second side wall 222. Using the end of the second side wall 222 as a fulcrum, the second base plate 30 rotates clockwise (clockwise in the figure), and the maintenance port 12 is opened until the first plate... The connection between 21 and the first side wall 221 abuts against the third side wall 321, and the end of the second side wall 222 abuts against the connection between the fifth side wall 323 and the sixth side wall 324. The second base plate 30 is rotated to the maximum angle and fixed. The section of the second plate 31 away from the second connecting part 32 is suspended in the air without human support. At this time, the second volute 1611b can be disassembled and taken out through the second maintenance port 12 to clean or repair the components in the second cavity 112. The centrifugal fan 161 and motor 162 can also be further disassembled for maintenance as needed.

[0076] When the maintenance port 12 needs to be closed after cleaning, repairing or replacing the centrifugal fan assembly 16, first push the second base plate 30 to rotate counterclockwise (counterclockwise direction in the figure). When the second plate 31 is aligned with the first plate 21, slide the second base plate 30 towards the air outlet so that the buckle 33 on the second base plate 30 is engaged in the slot 13 of the housing 10. At this time, the fixing part 34 on the second base plate 30 is aligned with the connecting structure on the side of the housing 10 with the return air port. Tighten the screws through to fix it, so as to achieve a tight fixation between the second base plate 30 and the housing 10.
