[0049] In order to install the ducted air conditioner 30 in the room, a suspended ceiling 10 needs to be installed on the ceiling 20 of the room.

[0050] Figures 1 to 3 The installation method of the ducted air handling unit 30 is shown. The ducted air handling unit 30 is installed inside the suspended ceiling 10, which has a ceiling return air inlet 11, a ceiling air outlet 12, and a ceiling access panel 13. The ceiling air outlet 12 is located on the side of the suspended ceiling 10, while the ceiling return air inlet 11 and the ceiling access panel 13 are located on the lower surface of the suspended ceiling 10. The ceiling access panel 13 is located to the side of the ceiling return air inlet 11 along its length, i.e., along the length of the ceiling return air inlet 11. Figures 1 to 3 One of the two sides in the left-right direction.

[0051] The installation position of the ducted air unit 30 is determined by the positions of the ceiling return air inlet 11 and the ceiling air outlet 12. Under the action of the fan, the air in the room is drawn into the ducted air unit 30 through the ceiling return air inlet 11. After being regulated by the ducted air unit 30, it is then sent back into the room through the ceiling air outlet 12 to achieve air circulation.

[0052] The height of the suspended ceiling 10 is limited, that is, the suspended ceiling 10 along... Figure 1 and Figure 3 The dimensions in the vertical direction are limited. Generally speaking, the height of the ceiling 10 is only slightly larger than the dimension of the duct unit 30 along the height direction of the ceiling 10.

[0053] Figure 4 The overall structure of the ducted air conditioner 30 is further illustrated. The ducted air conditioner 30 typically includes a housing 31 enclosed by multiple plate-like components, and the housing 31 includes a top cover 317. Due to the limited height of the ceiling 10, the gap between the ceiling 20 and the ducted air conditioner 30 is insufficient to provide the necessary operating space for disassembling the top cover 317. Therefore, the method of further disassembling the electric heater 34 by opening the top cover 317 is not feasible, resulting in maintenance difficulties.

[0054] In view of this, in order to improve the above problems, refer to Figures 1 to 10Some embodiments of the present disclosure provide a ducted air conditioner, comprising a casing 31, a partition 32 and an electric heater 34.

[0055] The partition 32 divides the internal space of the casing 31 into a return air cavity 311 and an outlet air cavity 312 arranged along a first direction X, and the partition 32 is provided with at least one suction port 321 for mounting a fan 33. The electric heater 34 is detachably arranged in the outlet air cavity 312 relative to the casing 31. In a state where the fan 33 is not mounted in the suction port 321, the suction port 321 communicates the return air cavity 311 and the outlet air cavity 312 to provide a space for detaching the electric heater 34 from the return air cavity 311 side, and the casing 31 is provided with an operation port 315 on a side of an end thereof along a second direction Y perpendicular to the first direction X, and the operation port 315 communicates with the outlet air cavity 312 to provide a space for taking out the detached electric heater 34 from the outlet air cavity 312.

[0056] Optionally, the return air cavity 311 is provided with a return air port, and the outlet air cavity 312 is provided with an outlet air port 314, in a state where the ducted air conditioner 30 is installed in the interior of the ceiling 10, the return air port is close to and positionally corresponds to the ceiling return air port 11, the outlet air port 314 is close to and positionally corresponds to the ceiling outlet air port 12, and the operation port 315 is close to and positionally corresponds to the ceiling maintenance port 13. Optionally, the ducted air conditioner 30 comprises an evaporator 371 mounted along the air flow direction upstream of the outlet air port 314.

[0057] Optionally, the ducted air conditioner 30 comprises a plurality of fans 33, and the partition 32 is correspondingly provided with a plurality of suction ports 321 arranged along the second direction Y at intervals. The fan 33 can be fixed to the partition 32 by a connecting member such as a threaded fastener, and the fan 33 can be detached from the partition 32 by detaching the connecting member.

[0058] When the ducted air conditioner 30 provided by the embodiments of the present disclosure needs to be maintained, a maintenance personnel can first detach the fan 33 from the return air cavity 311 side by means of the ceiling return air port 11, thereby leaving sufficient operating space for removing the electric heater 34; then, the maintenance personnel can detach the electric heater 34 from the return air cavity 311 side of the ducted air conditioner 30 by means of the ceiling return air port 11, and the electric heater 34 falls onto the casing 31 at the bottom of the outlet air cavity 312; finally, the maintenance personnel can take out the electric heater 34 falling onto the casing 31 at the bottom of the outlet air cavity 312 by means of the ceiling maintenance port 13 and manually extending into the operation port 315.

[0059] Therefore, the ducted air conditioner 30 provided by the embodiment of the present disclosure can disassemble the electric heater 34 and take out the electric heater 34 from the casing 31 of the ducted air conditioner 30 without disassembling the upper cover plate 317 and damaging the suspended ceiling 10, which is convenient and fast, can improve the maintenance efficiency and reduce the maintenance cost, thereby improving the product competitiveness and user satisfaction of the ducted air conditioner 30 and the air conditioning system.

[0060] In some embodiments, referring to Figure 7 、 Figure 8 and Figure 10 , the electric heater 34 is fixed relative to the casing 31 by the fastener 35, and the operating end of the fastener 35 is arranged towards the partition plate 32.

[0061] The operating end of the fastener 35 refers to the end of the fastener 35 that is in contact with and interacts with the disassembly tool 40. Optionally, the fastener 35 is a threaded fastener, such as a screw, in which case the operating end of the fastener 35 refers to the end of the screw head. Accordingly, according to the specific specifications of the threaded fastener, the disassembly tool 40 of the fastener 35 can be a hexagonal wrench, a screwdriver, or the like, and the axis of the fastener 35 can be arranged along the first direction X or at an angle to the first direction X.

[0062] Optionally, referring to Figure 7 , the ducted air conditioner 30 includes a bracket 38 arranged on the side of the evaporator 371 away from the air outlet 314, the bracket 38 is provided with a fixing hole 381, and the fastener 35 fixes the electric heater 34 to the bracket 38 by cooperating with the fixing hole 381. The electric heater 34 is fixed relative to the casing 31 by the bracket 38 and the evaporator 371.

[0063] In this embodiment, the operating end of the fastener 35 is towards the partition plate 32, which facilitates the disassembly tool 40 inserted into the air suction port 321 to align with the fastener 35, thereby facilitating the disassembly of the fastener 35.

[0064] In some embodiments, referring to Figure 9 , in the state that the electric heater 34 is fixed relative to the casing 31, the first end and the second end of the electric heater 34 are fixed relative to the casing 31 by different fasteners 35 along the second direction Y, and the arrangement positions of the fasteners 35 and the arrangement position of the air suction port 321 satisfy the following relationship:

[0065]

[0066]

[0067] Wherein, L1 represents the distance along the second direction Y between the fastener 35 located at the first end of the electric heater 34 and the side closest to the first end of the electric heater 34 of the at least one air intake 321; L2 represents the distance along the second direction Y between the fastener 35 located at the second end of the electric heater 34 and the side closest to the second end of the electric heater 34 of the at least one air intake 321; d represents the distance along the first direction X between the fasteners 35 located at both ends of the electric heater 34 and the air intake 321; H represents the preset length; α is less than or equal to the first preset angle; and β is less than or equal to the second preset angle.

[0068] Optionally, the partition 32 is provided with two air intakes 321 spaced apart along the second direction Y, and the first end of the electric heater 34 along the second direction Y is... Figure 6 and Figure 9 The middle is located at one end on the left, and the second end is... Figure 6 and Figure 9 The middle part is located at the right end. Figure 6 and Figure 9 In the middle, the left side of the air intake 321 located on the left is the side of the air intake 321 closest to the first end of the electric heater 34, and the right side of the air intake 321 located on the right is the side of the air intake 321 closest to the second end of the electric heater 34.

[0069] In this embodiment, reference Figure 9 The preset length H can be used to represent the size of the disassembly tool 40 for fastener 35, and its value can be determined according to the specific specifications of the disassembly tool 40. The values ​​of the first preset angle and the second preset angle can be determined through experiments or theoretical calculations based on the specific specifications of the disassembly tool 40.

[0070] To remove fastener 35, a certain torque needs to be applied to loosen it. Based on the positional relationship between the fastener 35 and the air intake 321 in this embodiment, if angles α and β are too large, it will be difficult for maintenance personnel to apply force using the disassembly tool 40. By limiting the values ​​of angles α and β to less than a preset value, maintenance personnel can have a larger range of hand movement when holding the disassembly tool 40 and inserting it into the air intake 321, making it easier to apply force and thus apply sufficient torque to the fastener 35 using the disassembly tool 40.

[0071] In some embodiments, reference Figure 9In the state that the electric heater 34 is fixed relative to the casing 31, along the second direction Y, the arrangement position of the fastener 35 located at the first end of the electric heater 34 is farther away from the second end of the electric heater 34 than the side edge of the at least one air inlet 321 closest to the first end of the electric heater 34, and the arrangement position of the fastener 35 located at the second end of the electric heater 34 is farther away from the first end of the electric heater 34 than the side edge of the at least one air inlet 321 closest to the second end of the electric heater 34, wherein the first preset angle is smaller than the second preset angle.

[0072] Since most maintenance personnel are right-handed, based on the positional relationship between the fastener 35 and the air inlet 321 in the embodiment, compared with disassembling the fastener 35 located at the second end of the electric heater 34, when disassembling the fastener 35 located at the first end of the electric heater 34, the arm of the maintenance personnel needs to rotate a larger angle in order to hold the disassembling tool 40, which is relatively inconvenient to exert force. Considering the structural characteristics of the human arm and the way of holding the disassembling tool 40 when the arm is in different positions, in the embodiment, the first preset angle is smaller than the second preset angle, which can make the arm of the maintenance personnel not need to rotate too large an angle when disassembling the fastener 35 located at the first end of the electric heater 34, so that the fastener 35 at both ends of the electric heater 34 can be disassembled, and sufficient torque can be exerted on the fastener 35.

[0073] In some embodiments, the first preset angle is 30°, and the second preset angle is 30°.

[0074] That is, the angle α and the angle β satisfy the following relationship:

[0075]

[0076]

[0077] In some embodiments, the first preset angle is 30°, and the second preset angle is 40°.

[0078] That is, the angle α and the angle β satisfy the following relationship:

[0079]

[0080]

[0081] In the embodiment, the values of the first preset angle and the second preset angle are preferred values, based on the above values, the maintenance personnel can exert sufficient torque on the fastener 35 through the disassembling tool 40, thereby facilitating the disassembly of the electric heater 34.

[0082] In some embodiments, in the state that the electric heater 34 is fixed relative to the casing 31, the length direction of the electric heater 34 is consistent with the second direction Y, and the end face of the end of the electric heater 34 along the length direction thereof is arranged towards the operation opening 315.

[0083] Based on the arrangement mode of the electric heater 34 in the state that the electric heater 34 is fixed relative to the casing 31 in the present embodiment, when the electric heater 34 is removed, the electric heater 34 falls onto the casing 31 at the bottom of the air outlet cavity 312, after falling onto the casing 31 at the bottom of the air outlet cavity 312, the length direction of the electric heater 34 is still substantially along the second direction Y, and the end face of the end of the electric heater 34 along the length direction thereof is still substantially towards the operation opening 315, and such falling mode facilitates the maintenance personnel to hold the end of the electric heater 34 along the length direction thereof and to take out the electric heater 34 from the air outlet cavity 312 along the second direction Y.

[0084] In some embodiments, referring to Figure 10 , the operation opening 315 comprises a taking area 316 for the removed electric heater 34 to pass through, and the size of the electric heater 34 and the size of the taking area 316 satisfy the following relationship:

[0085]

[0086]

[0087] wherein L5 represents the size of the taking area 316 along the third direction Z perpendicular to the first direction X and the second direction Y, L6 represents the size of the taking area 316 along the first direction X, w represents the size of the electric heater 34 along the width direction thereof, and h represents the size of the electric heater 34 along the height direction thereof.

[0088] Figure 8 The arrow direction in the above figure represents the direction of taking out through the operation opening 315. Figure 10 In the above figure, the area inside the dashed box is the taking area 316. The taking area 316 may, for example, be a rectangular area. In the state that the electric heater 34 is fixed relative to the casing 31, the end face of the end of the electric heater 34 along the length direction thereof can be seen through the taking area 316.

[0089] The mechanical model of manually taking the electric heater 34 is a laborious lever, and in the process of taking out the electric heater 34, the arm of the maintenance personnel is prone to shaking at the operation opening 315. The size of the taking area 316 in the present embodiment takes into account the size of the electric heater 34 itself and the amplitude of the shaking of the arm of the maintenance personnel when taking out the electric heater 34, and in the process of taking out the electric heater 34, the electric heater 34 and the arm of the maintenance personnel can be made to interfere with the edges of the operation opening 315 and other components or structures inside the air outlet cavity 312 as little as possible, so as to ensure that the electric heater 34 is smoothly taken out.

[0090] In some embodiments, the ducted air conditioner 30 comprises an evaporator pipe 372 and / or a water pump 373, which are arranged at the same end of the casing 31 along the second direction Y as the operation port 315; the operation port 315 comprises a taking area 316 through which the discharged electric heater 34 passes, and the side edge of the taking area 316 close to the return air cavity 311 is located on the plane where the end face of the partition plate 32 towards the outlet air cavity 312 is located.

[0091] The evaporator pipe 372 and the water pump 373 are matched components of the evaporator 371. Optionally, referring to Figure 7 , the evaporator pipe 372 and the water pump 373 are arranged at the side close to the side surface 318 of the air outlet 314.

[0092] Figure 10 In the above embodiment, the side edge of the taking area 316 on the left side is the side edge of the taking area 316 close to the return air cavity 311.

[0093] Considering that the evaporator pipe 372 and / or the water pump 373 have occupied a considerable part of the space of the position of the outlet air cavity 312 close to the side surface 318 along the first direction X, the space left for taking the electric heater 34 is limited. In the embodiment, the side edge of the taking area 316 close to the return air cavity 311 is flush with the end face of the partition plate 32 towards the outlet air cavity 312, which can utilize the remaining space of the position of the outlet air cavity 312 close to the side surface 318 along the first direction X as much as possible, and ensure that there is sufficient space to take out the electric heater 34.

[0094] In some embodiments, referring to Figure 6 and Figure 10 , the ducted air conditioner 30 comprises a first cover plate 361 and a second cover plate 362 which are arranged separately and detachably mounted on the operation port 315, the first cover plate 361 is configured to at least close the taking area 316, and the second cover plate 362 is configured to at least close the area of the operation port 315 corresponding to the position of the evaporator pipe 372 and / or the water pump 373.

[0095] The shapes of the first cover plate 361 and the second cover plate 362 can be rectangular, or Figure 6 and Figure 10The stepped shape can be determined according to the arrangement positions of the evaporator pipe 372 and the water pump 373. Alternatively, the first cover plate 361 and the second cover plate 362 can be detachably connected to the side surface 318 of the casing 31 by screws or other connecting members.
