Description

Technical Field

[0001] This utility model relates to the field of air conditioner technology, and in particular to a ducted air conditioner and an air conditioning system having the ducted air conditioner. Background Technology

[0002] A ducted air conditioner, also known as a ducted indoor unit, consists of a fan unit and a heat exchange unit, connected to ducts to deliver air into the room. Ducted air conditioners are typically suspended from the ceiling, which is usually decorated with a suspended ceiling.

[0003] A split-type duct air conditioner is provided, comprising a first module and a second module arranged side by side; a first upper connector located in one of the first and second modules; and a second upper connector located in the other of the second and first modules. The first upper connector defines a first mounting groove with one open side, and the second upper connector forms a first mounting portion corresponding to the shape of the first mounting groove. The first mounting portion is inserted into the first mounting groove and fixedly connected by a first fastener. This design, with the duct air conditioner as two modules, allows each module to be transported separately to an installation point, where they are then assembled into a single unit, avoiding the problem of difficult handling due to the overall weight of the unit.

[0004] However, the mounting slot of the aforementioned split-type duct air conditioner is designed to extend through the left and right directions. When the mounting part is inserted into the slot for initial connection, the through-slot cannot provide proper positioning between the two modules in the left and right direction. This results in misalignment of the upper connecting holes of the two modules in the left and right direction. Installers must then adjust the left and right positions of the two modules to align the upper connecting holes before the first fastener can be securely connected to the upper connecting holes of the two modules. This increases the installation effort and reduces installation efficiency. Furthermore, to secure the two modules in the left and right direction, the aforementioned split-type duct air conditioner requires the addition of cover plates and connecting plates on both sides of the two modules, which are then installed on the left and right sides of the two modules using screws. This increases the number of components that need to be installed, further reducing installation efficiency. Utility Model Content

[0005] To achieve the primary objective of this utility model, it provides a modularly assembled ductwork unit that significantly reduces the intensity of manual handling and the number of installation components, thereby reducing installation effort and improving installation efficiency.

[0006] To achieve the second objective of this utility model, this utility model provides an air conditioning system having the above-mentioned duct unit.

[0007] To achieve the first objective of this utility model, it provides a ducted air conditioner, including a fan module and a heat exchange module. The fan module's first outer casing has an air inlet on its inlet wall and an air outlet on its outlet wall. The heat exchange module's second outer casing has an air inlet on its inlet wall and an air outlet on its outlet wall. The outlet can connect with the inlet. One of the outlet and inlet walls is provided with a hook, and the other is provided with a slot, which includes a communicating engaging section. The insert section and the engaging section are located above the insert section, and the engaging groove of the engaging section is smaller than the insert groove of the insert section. The hook includes a support arm and a hook arm connected to each other. The end of the support arm away from the hook arm is connected to the air outlet wall / air inlet wall. The hook arm extends upward away from the support arm and has an engaging gap with the air outlet wall / air inlet wall. The hook arm can pass through the slot and hook onto the inner side of the air outlet wall / air inlet wall. The air outlet wall / air inlet wall can be inserted into the engaging gap. The upper end face of the engaging section can abut against the support arm.

[0008] As can be seen from the above solution, this utility model of duct air conditioner allows for quick disassembly into a fan module and a heat exchange module. The fan module and heat exchange module can be transported to the installation position separately for rapid assembly, significantly reducing manual handling intensity and improving installation efficiency. Furthermore, during the modular assembly of this utility model's duct air conditioner, the fan module and heat exchange module are connected via hooks and slots. Since the slot includes a connected engaging section and an inserting section, with the engaging section located above the inserting section, and the engaging slot width of the engaging section being smaller than the inserting slot width of the inserting section, the hook arm first inserts through the inserting section of the slot to achieve initial positioning in the left-right direction. The relatively wider inserting slot of the inserting section ensures smooth and rapid initial positioning of the hook arm, avoiding multiple adjustments due to misalignment between the hook and slot. The entire assembly of the hook moves upwards to engage, causing the upper end of the engaging section of the slot to abut against the support arm of the hook. The air outlet / inlet wall is inserted into the engagement gap between the hook arm and the air outlet / inlet wall, allowing the hook arm to engage with the inner side of the air outlet / inlet wall. Because the width of the engaging groove in the engaging section is smaller than the width of the insertion groove in the insertion section, precise positioning in the left-right direction is achieved. Furthermore, the upper end of the engaging section of the slot abuts against the support arm of the hook, limiting movement in the up-down direction, thus improving installation accuracy. In addition, this utility model of a ducted air conditioner only uses hooks and slots for quick insertion, positioning, and engagement between the fan module and heat exchange module, enabling precise and rapid assembly of the fan module and heat exchange module. This significantly reduces the number of components required for installation, thereby reducing installation effort and improving installation efficiency. In addition, the fan module and heat exchange module of this utility model air duct unit are stably suspended by hooks and slots, so that the air duct unit as a whole will not tilt or fall due to loss of support, thus improving the safety of subsequent maintenance operations.

[0009] Therefore, this utility model of duct air conditioner is composed of a fan module and a heat exchange module, which can significantly reduce the intensity of manual handling. Moreover, the fan module and the heat exchange module are only equipped with hooks and slots for quick plug-in, positioning and engagement, which can achieve precise and rapid assembly between the fan module and the heat exchange module. This can greatly reduce the number of parts to be installed, thereby reducing the installation intensity and improving the installation efficiency.

[0044] First embodiment of ducted air conditioner: See Figures 1 to 7This embodiment discloses a ducted air conditioner 10, including a fan module 12 and a heat exchange module 11. The fan module 12 has an air inlet 1211 on its first outer shell 121 and an air outlet 1214 on its outlet wall 1214. The heat exchange module 11 has an air inlet 1121 on its second outer shell 111 and an air outlet 12141 on its second outer shell 111. The outlet 12141 is connected to the air inlet 1121. Specifically, the fan module 12 further includes a centrifugal fan 125, which is disposed inside the first outer shell 121. The volute exhaust port of the centrifugal fan 125 is connected to the outlet 12141 on the outlet wall 1214 of the first outer shell 121. The heat exchange module 11 further includes an evaporator, which is disposed inside the second outer shell 111.

[0045] In this embodiment, one of the air outlet wall 1214 of the first outer shell 121 and the air inlet wall 112 of the second outer shell 111 is provided with a hook 113, and the other of the air outlet wall 1214 of the first outer shell 121 and the air inlet wall 112 of the second outer shell 111 is provided with a slot 123. The slot 123 includes a connected engaging section 1231 and an inserting section 1232. The engaging section 1231 is located above the inserting section 1232, and the width of the engaging slot of the engaging section 1231 is smaller than the width of the inserting slot of the inserting section 1232. The hook 113 includes a connected support arm 11. 31 and hook arm 1132, one end of support arm 1131 away from hook arm 1132 is connected to air outlet wall 1214 / air inlet wall 112, hook arm 1132 extends upward away from support arm 1131 and has a locking gap between it and air outlet wall 1214 / air inlet wall 112, so that hook arm 1132 can pass through slot 123 and hook onto the inner side of air outlet wall 1214 / air inlet wall 112, air outlet wall 1214 / air inlet wall 112 can be inserted into the locking gap, and the upper end face of locking section 1231 can abut against support arm 1131.

[0046] In this embodiment, the duct air conditioner 10 can be quickly disassembled into a fan module 12 and a heat exchange module 11. The fan module 12 and the heat exchange module 11 can be transported to the installation position respectively and then quickly assembled, which greatly reduces the intensity of manual handling and improves installation efficiency. Furthermore, during the modular assembly of the duct unit 10 in this embodiment, the fan module 12 and the heat exchange module 11 are connected by a hook 113 and a slot 123. Since the slot 123 includes a connected engaging section 1231 and an inserting section 1232, with the engaging section 1231 located above the inserting section 1232 and the width of the engaging slot of the engaging section 1231 being smaller than the width of the inserting slot of the inserting section 1232, the hook arm 1132 of the hook 113 first inserts through the inserting section 1232 of the slot 123 to achieve initial positioning in the left-right direction. The relatively larger inserting slot of the inserting section 1232 ensures that the initial insertion and positioning of the hook arm 1132 of the hook 113 is smooth and fast, avoiding multiple adjustments due to misalignment between the hook 113 and the slot 123. This affects installation efficiency. Subsequently, the hook 113 moves upward and engages, causing the upper end face of the engaging section 1231 of the slot 123 to abut against the support arm 1131 of the hook 113. The air outlet wall 1214 / air inlet wall 112 is inserted into the engagement gap between the hook arm 1132 and the air outlet wall 1214 / air inlet wall 112, so that the hook arm 1132 of the hook 113 engages with the inner side of the air outlet wall 1214 / air inlet wall 112. Because the engagement groove width of the engaging section 1231 is smaller than the insertion groove width of the insertion section 1232, precise positioning in the left and right directions is achieved. The upper end face of the engaging section 1231 of the slot 123 abuts against the support arm 1131 of the hook 113, so as to limit the vertical direction, thereby improving installation accuracy. Furthermore, in this embodiment, the fan module 12 and heat exchange module 11 of the ducted air conditioner 10 are only equipped with hooks 113 and slots 123 for quick insertion, positioning, and engagement, enabling precise and rapid assembly between them. This significantly reduces the number of components required for installation, thereby reducing installation stress and improving installation efficiency. In addition, the fan module 12 and heat exchange module 11 of the ducted air conditioner 10 are stably suspended by the hooks 113 and slots 123, preventing the ducted air conditioner 10 from tilting or falling due to loss of support, thus improving the safety of subsequent maintenance operations.

[0047] Therefore, in this embodiment, the duct unit 10 is modularly assembled from a fan module 12 and a heat exchange module 11, which can significantly reduce the intensity of manual handling. Furthermore, only hooks 113 and slots 123 are provided between the fan module 12 and the heat exchange module 11 for quick insertion, positioning, and engagement, which can achieve precise and rapid assembly between the fan module 12 and the heat exchange module 11. This can significantly reduce the number of installed parts, thereby reducing the installation intensity and improving installation efficiency.

[0048] Specifically, in this embodiment, a slot 123 is provided on the air outlet wall 1214 of the first outer shell 121 of the fan module 12, and correspondingly, a hook 113 is provided on the air inlet wall 112 of the second outer shell 111 of the heat exchange module 11. To further improve the assembly stability between the fan module 12 and the heat exchange module 11, a nut 114 is riveted to the air inlet wall 112 of the second outer shell 111 of the heat exchange module 11, and a mounting hole 124 is provided on the air outlet wall 1214 of the first outer shell 121 of the fan module 12. A first fastener can be detachably passed through the mounting hole 124 and threadedly connected to the nut 114, with the head of the first fastener abutting against the inner surface of the air outlet wall 1214. In this embodiment, the first fastener can be a screw, bolt, or other threaded connector.

[0049] To improve the smooth transition of the hook 113 from the insertion section 1232 of the slot 123 to the engagement section 1231 of the slot 123, in this embodiment, the engagement section 1231 and the insertion section 1232 are connected by an inclined groove surface 1233. Furthermore, to further improve the smoothness of the hook 113's insertion into the slot 123, in this embodiment, the inner side 11321 of the hook arm 1132 adjacent to the engagement gap is inclined outwards from bottom to top, and the outer upper surface 11322 of the hook arm 1132 away from the engagement gap is arc-shaped, and the lower surface 11311 of the support arm 1131 is V-shaped.

[0050] In order to guide the incoming air, the fan module 12 in this embodiment also includes an air guide ring 122, which extends in a closed loop along the periphery of the air inlet 12111 and is located on the outer side of the air inlet wall 1211 of the first housing 121.

[0051] Combination Figures 8 to 14 In this embodiment, the air inlet wall 1211 of the first outer shell 121 of the fan module 12 can be detachably located at one of the following positions: the upper end of the first outer shell 121, the lower end of the first outer shell 121, or the outer side of the first outer shell 121 opposite to the air outlet wall 1214. This allows for flexible switching between top, bottom, or side return air modes, solving the problem that the existing ducted air conditioner 10 has a single return air mode and cannot be flexibly adjusted according to the installation environment. This enhances the product's adaptability, allowing users to flexibly choose the return air mode according to the actual installation environment without replacing the entire outer shell structure, significantly improving the product's applicability and user experience.

[0052] To achieve universal installation, the first housing 121 in this embodiment also includes two end caps 1212 and two side caps 1213. The two side caps 1213 are detachably located on the left and right sides of the air outlet wall 1214, and the two end caps 1212 are detachably connected to the two side caps 1213. The two end caps 1212 are located at two positions: the upper end of the first housing 121, the lower end of the first housing 121, and the outer side of the first housing 121 opposite to the air outlet wall 1214.

[0053] Specifically, in this embodiment, a first plate 12131 is provided on the inner side of the upper end of each side cover 1213, and the first plate 12131 has a first groove 12132. A second plate is provided on the inner side of the lower end of each side cover 1213, and the second plate has a second groove. Furthermore, a third plate 12133 is provided on the inner side of the outer end of each side cover 1213 away from the air outlet wall 1214, and each third plate 12133 has a third groove 12134 and a fourth groove 12135. In addition, in this embodiment, each end cover 1212... The left and right inner sides are respectively provided with buckles 12123. The buckles 12123 of the two end caps 1212 can be inserted and hooked into two of the first groove 12132, the second groove, the third groove 12134, and the fourth groove 12135. The two end caps 1212 can cover the outer surface of two of the first plate 12131, the second plate, and the third plate 12133. The air inlet wall 1211 can cover the outer surface of the other plate of the first plate 12131, the second plate, and the third plate 12133.

[0054] In this embodiment, the air inlet wall 1211 of the first outer shell 121 of the fan module 12 is located on the outer side opposite to the air outlet wall 1214 of the first outer shell 121 to achieve side air return. Thus, one end cap 1212 covers the first plate 12131 at the upper end of the two side caps 1213, and the buckles 12123 on the left and right inner sides of the end cap 1212 covering the upper end of the two side caps 1213 are inserted and hooked into the first groove 12132 of the first plate 12131. An end cap 1212 covers the second plate at the lower end of the two side caps 1213, and the buckles 12123 on the left and right inner sides of the end cap 1212 at the lower end of the two side caps 1213 are inserted and hooked into the second groove of the second plate. At the same time, the air inlet wall 1211 covers the third plate 12133 on the inner side of the outer end of the two side caps 1213 away from the air outlet wall 1214, and the air inlet wall 1211 is detachably threadedly connected to the third plate 12133 by a second fastener. In this embodiment, the second fastener can be a screw, bolt or other threaded connector.

[0055] To improve the smoothness of the insertion and engagement and the accuracy of positioning, the first groove 12132 in this embodiment includes a first groove segment 121321 and a second groove segment 121322 that are connected. The first groove segment 121321 is located at the end of the second groove segment 121322 near the air outlet wall 1214, and the first groove width of the first groove segment 121321 is smaller than the second groove width of the second groove segment 121322. The front end face of the first groove segment 121321 near the air outlet wall 1214 can abut against the stop arm of the buckle 12123. Furthermore, the second groove in this embodiment includes a third groove segment and a fourth groove segment that are connected. The third groove segment is located at the end of the fourth groove segment near the air outlet wall 1214, and the third groove width of the third groove segment is smaller than the fourth groove width of the fourth groove segment. The front end face of the third groove segment near the air outlet wall 1214 can abut against the stop arm of the buckle 12123. In this embodiment, the third groove 12134 is located above the fourth groove 12135. The third groove 12134 includes a fifth groove segment 121341 and a sixth groove segment 121342 that are connected. The fifth groove segment 121341 is located below the sixth groove segment 121342. The fifth groove width of the fifth groove segment 121341 is smaller than the sixth groove width of the sixth groove segment 121342. The lower end face of the fifth groove segment 121341 can abut against the stop arm of the buckle 12123. The fourth groove 12135 includes a seventh groove segment 121351 and an eighth groove segment 121352 that are connected. The seventh groove segment 121351 is located above the eighth groove segment 121352. The seventh groove width of the seventh groove segment 121351 is smaller than the eighth groove width of the eighth groove segment 121352. The upper end face of the seventh groove segment 121351 can abut against the stop arm of the buckle 12123.

[0056] To further improve the smoothness of the plug-in connection, in this embodiment, the first slot segment 121321 and the second slot segment 121322 are connected by a first inclined surface 121323; in this embodiment, the third slot segment and the fourth slot segment are connected by a second inclined surface; in this embodiment, the fifth slot segment 121341 and the sixth slot segment 121342 are connected by a third inclined surface 121343; and in this embodiment, the seventh slot segment 121351 and the eighth slot segment 121352 are connected by a fourth inclined surface 121353.
