Description

Detachable duct machine Technical Field

[0001] The present invention relates to the field of air conditioning, in particular to a detachable air duct unit. Background Art

[0002] Conventional ducted air conditioners typically feature a monolithic structure with a sheet metal housing. This depth, length, and weight make them difficult to fit through narrow passages and difficult to transport. Installation requires the assistance of multiple personnel or the use of lifting equipment, resulting in high labor intensity and labor costs. Furthermore, after-sales maintenance often requires the complete removal of side panels or covers. Overall, ducted air conditioners are extremely inconvenient to transport, install, and maintain.

[0003] The prior art also proposes a split-type ducted air conditioner with a blowing structure (the fan is located on the return air side, and the heat exchanger is located on the outlet air side). The two parts are supported by a middle partition and also include at least one connector, which is fixedly connected to the upper end and / or lower end of the middle partition respectively. The cover plate and / or the bottom plate are respectively provided with a card slot on the left and right sides of the middle partition, and at least part of the connector rests in the card slot to form a card-locked fixation. The split-type ducted air conditioner proposed in this patent has a connector that is engaged with the cover plate and the bottom plate only through the card slot, and the relative angle between the connector and the cover plate is a right angle or an obtuse angle, resulting in low bearing capacity. In the event of long-term operation or instantaneous impact such as falling during transportation, there is a risk that the two parts will become disconnected or separated.

[0004] The prior art also proposes a ducted air conditioner comprising a first housing housing a fan unit and a second housing housing an evaporator. A detachable unit is provided between the first and second housings, detachably connected to the first and second housings. This ducted air conditioner achieves modular assembly, improving assembly efficiency. However, the presence of a detachable unit in the middle of a detachable ducted air conditioner complicates assembly.

[0005] In view of this, the present invention is proposed.

They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the present invention.

[0040] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," "connected," "in contact," and "connected" should be understood broadly. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; and direct or indirect connections through an intermediary. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0041] The present application proposes a split duct unit, and the overall structure of the split duct unit of the heat exchanger is shown in Figures 1, 2 and 3. Figure 1 shows a schematic diagram of the duct unit of the first embodiment of the present application after assembly, Figure 2 shows a schematic diagram of the duct unit of the first embodiment of the present application after disassembly, and Figure 3 shows a side view of the disassembled duct unit. As shown in Figures 1, 2 and 3, the duct unit can be disassembled into a first component 1 and a second component 2. The first component 1 and the second component 2 are horizontally spliced ​​to reduce the weight and size of a single unit. As shown in Figure 2, the first component 1 includes an upper cover plate 11, a lower cover plate 12, a left side plate 13 and a right side plate 14. The four outer shell sheet metal parts of the first component 1, namely the upper cover plate 11, the lower cover plate 12, the left side plate 13 and the right side plate 14, are connected in sequence by fasteners such as screws. The second component 2 includes an upper cover plate 21, a lower cover plate 22, a left side plate 23, and a right side plate 24. The four outer shell sheet metal components of the second component 2 are connected in sequence by fasteners such as screws. When the first component 1 is on the fan side, the second component 2 is on the evaporator side. When the first component 1 is on the evaporator side, the second component 2 is on the fan side. The fan outlet can be away from the connection between the first component 1 and the second component 2 (suction-type ducted air conditioner) or toward the connection between the first component 1 and the second component 2 (blow-type ducted air conditioner).

[0042] The fixing screws of the upper cover plate 11 and the lower cover plate 12 of the first component 1 and the left side plate 13 and the right side plate 14, as well as the fixing screws of the upper cover plate 21 and the lower cover plate 22 of the second component and the left side plate 23 and the right side plate 24, are similar to those of conventional duct machines and have nothing to do with the detachable structure, and are not specifically mentioned here.

[0043] Except for features such as screw holes and notches for assembly with other parts in the duct unit, the upper cover 11 and the lower cover 12 of the first component 1 are exactly the same in size, structure and bending angle, the upper cover 21 and the lower cover 21 of the second component 2 are exactly the same in size, structure and bending angle, the left side panel 13 and the right side panel 14 of the first component 1 are exactly the same in size, structure and bending angle, and the left side panel 23 and the right side panel 24 of the second component 2 are exactly the same in size, structure and bending angle. Only one of the part features with the same size, structure and bending angle is described here.

[0044] Figure 4 shows a perspective schematic diagram of the lower cover of the first component of the ducted air conditioner according to the first embodiment of the present application, and Figure 5 shows a side view of the lower cover of the first component of the ducted air conditioner according to the first embodiment of the present application. As shown in Figures 4 and 5, the edge of the lower cover 12 of the first component 1 is provided with an obtuse-angled hem 111, with a bending angle of α (the angle between the obtuse-angled hem 111 and the horizontal plane). The obtuse-angled hem 111 has a plurality of screw holes 112 (depending on the length of the entire unit, the spacing between adjacent screw holes is preferably set to 200-350 mm).

[0045] FIG6 is a perspective schematic diagram of the right side panel of the first component of the ducted air conditioner according to the first embodiment of the present application, and FIG7 is a front view of the right side panel of the first component of the ducted air conditioner according to the first embodiment of the present application. As shown in FIG6 and FIG7, the right side panel 13 of the first component 1 is provided with a right-angled fold 132, on which there are several screw holes (depending on the length of the entire unit, adjacent screw holes are preferably arranged with a spacing of 200 to 350 mm, and a ducted air conditioner with a large cooling capacity generally has 2 to 3 screws). The corner of the right side panel 13 of the first component 1 on the side where it connects to the second component 2 is provided with a chamfer. The angle of the chamfer is the same as the bending angle of the lower cover 12 of the first component 1, both being α, so as to cooperate with the upper cover 11 and the lower cover 12.

[0046] FIG8 is a perspective schematic diagram of the lower cover of the second component of the duct unit of the first embodiment of the present application, and FIG9 is a side view of the lower cover of the second component of the duct unit of the first embodiment of the present application. As shown in FIG8 and FIG9, the lower cover 22 of the second component 2 is provided with a V-shaped hem 223. The bending angle of the first hem 223' extending toward the second component in the V-shaped hem 223 is β (the angle between the first hem 223' and the horizontal plane), and the bending angle of the second hem 223" extending away from the second component in the V-shaped hem 223 is γ (the angle between the second hem 223" and the horizontal plane). The second hem 223" extending away from the second component of the V-shaped hem 223 has a plurality of screw holes (depending on the length of the entire unit, adjacent screw holes are preferably arranged with a spacing of 200 to 350 mm).

[0047] FIG10 is a perspective view of the right side panel of the second component of the ducted air conditioner according to the first embodiment of the present application, and FIG11 is a front view of the right side panel of the second component of the ducted air conditioner according to the first embodiment of the present application. As shown in FIG10 and FIG11 , the right side panel 24 of the second component 2 is provided with a right-angled hem 244. The right-angled hem 244 extends in a direction opposite to the right-angled hem 132 of the right side panel 14 of the first component 1. The right-angled hem 244 has a plurality of screw holes (adjacent screw holes are arranged at intervals of 200 to 350 mm depending on the length of the entire unit, and typically 2 to 3 screw holes are provided for a ducted air conditioner with a high cooling capacity). The corner of the right side panel 24 on the side where it connects to the first component 1 is chamfered. The angle of the chamfer is the same as the angle of the lower cover 22 of the second component 2, both being γ, to facilitate mating with the upper cover 21 and the lower cover 22.

[0048] During the engineering installation, first align the first component 1 and the second component 2 according to the style of the split diagram, align the obtuse folded edge 111 of the lower cover plate 12 of the first component 1 with the V-shaped folded edge 223 of the lower cover plate 22 of the second component 2, and align the right-angled folded edge 132 of the right side plate 14 of the first component 1 with the right-angled folded edge 244 of the right side plate 24 of the second component 2. Push the first component 1 or the second component 2 until it is in close contact with the other component, and then tighten the fixing screws around it in sequence.

[0049] When the first component 1 and the second component 2 are spliced ​​together, the first component 1 and the second component 2 are two trapezoidal butt joints when viewed from the left or right side (as shown in the circle in FIG3 ). During the splicing process, the gap between the first component 1 and the second component 2 changes from large to small. The first component 1 and the second component 2 do not need to be lifted off the ground, and the butt joint can be easily completed.

[0050] Figure 12 shows a perspective view of the folded edge of the lower cover of the second component of the ducted air conditioner according to the first embodiment of the present application. Preferably, a folded edge 2231 is added to the outer edge of the second folded edge 223" extending away from the second component 2 within the V-shaped folded edge 223 of the lower cover 22 of the second component 2 to prevent the sharp edge from scratching hands diagonally upward.

[0051] Preferably, for a harmonious and beautiful appearance, the angle α and the angle γ are set to be equal, that is, ∠α=∠γ. In order for the upper and lower cover plates to fix the screws without exceeding the plane of the upper and lower cover plates, ∠α, ∠γ∈[90°, 150°] (if the angle is less than 90°, the air screw will be easily blocked by the fold itself when fixing the screws; if the angle is greater than 150°, it is difficult for the screw head to be lower than the plane of the upper and lower cover plates, unless the obtuse fold and the V-shaped fold of the upper and lower cover plates are very large, but this will affect the layout of other parts in the duct machine). Preferably, ∠α+∠β=180°, so that when the first component 1 and the second component 2 are matched, the outer side of the obtuse fold 111 of the first component 1 fits with the inner side of the first fold 223' extending toward the second component in the V-shaped fold 223 of the second component 2, thereby preventing problems such as condensation on the outer shell caused by air leakage after assembly.

[0052] Figure 13 is a three-dimensional diagram showing the first component and the second component of the second embodiment of the present application. As an alternative embodiment in which the folding edges of the left and right side panels of the above embodiment are set as right-angle folding edges, the folding edges of the left and right side panels are set to be the same as the folding edges of the upper and lower cover panels, and are designed to be obtuse-angle folding edges that cooperate with the V-shaped folding edges. In other words, the folding edges of the left side panel 13 and the right side panel 14 of the first component 1 are designed as obtuse-angle folding edges, and the folding edges of the left side panel 23 and the right side panel 24 of the second component 2 are designed as V-shaped folding edges, thereby achieving the obtuse-angle folding edges of the first component 1 and the V-shaped folding edges of the second component 2. In this alternative embodiment, when splicing the first component 1 and the second component 2, there is no need to deliberately align the screw holes on the left and right side panels. By guiding the bevel edges, it is easy to correctly dock and fix them.
