Each air guide vane slot 4 is provided with more than one slot position.

[0026] In the present invention, the wind guide curved plate 2 can be two straight plates with a certain angle or two curved plates with a circular arc transition, which have the function of changing the wind direction. On the corresponding side of the wind guide curved plate 2, only the wind guide plate 9 can be set, or only the wind guide piece 3 can be set, or the wind guide plate 9 and the wind guide piece 3 can be set at the same time. The function of setting the wind guide plate 9 and / or the wind guide piece 3 on the corresponding side of the wind guide curved plate 2 is to provide a complete air duct for the inlet and outlet elbows, wherein 1-4 wind guide pieces 3 are set at the end of the air duct. When the wind guide plate 9 is set, one wind guide piece 3 can be It is arranged on any one side or multiple sides of the end of the air duct. When the air guide plate 9 is not arranged, at least one air guide piece 3 is arranged on the corresponding side of the air guide curved plate 2, that is, at least one air guide piece 3 is arranged on the air inlet side and the air outlet side of the air inlet and outlet elbow. The air guide piece 3 of the present invention can be detachably installed by an air guide piece slot 4 having more than one slot position. The air guide piece 3 can be arranged on the side that needs to be installed in coordination with the central air conditioner outlet. The size of the air outlet end can be adjusted by adjusting the installation slot of the air guide piece 3, so that the air outlet of different models and sizes can be adapted. The more slots there are for the air guide plate card slot 4, the greater the adjustable size range and precision. The present invention preferably sets two air guide plates 3 on the side that is installed in cooperation with the central air conditioner outlet, and sets three slots for the air guide plate card slot 4 to achieve a balance between structural stability and adjustable range. One or two air guide plates 3 are set on the air outlet side of the air inlet and outlet elbow (i.e., the other side of the side that is installed in cooperation with the central air conditioner outlet), and the wind direction on the air outlet side can be changed according to actual needs. The present invention can be adjusted by the air guide plate card slot Multiple slots are combined to form inlet and outlet elbows of different specifications and sizes. One side is connected to the central air-conditioning outlet to facilitate adaptation to different types of central air-conditioning outlets. No customization is required, which can save costs. The other side can be installed through a combination of air guide plates 3 to adapt the interface or adjust the diameter or direction of the air outlet. The air guide plates 3 are detachably connected through the air guide plate slots 4, so that the air guide plates 3 can be produced or transported as accessories during transportation and production. At the same time, the installation quantity of the air guide plates 3 can also be selected according to needs to further reduce production and transportation costs.

[0027] When the number of slots is an odd number, the slots except the middle slot are mirror-symmetrical in pairs. When the number of slots is an even number, the slots are mirror-symmetrical in pairs, which can facilitate the adjustment and selection of dimensions. At the same time, the air guide blades 3 installed in the two symmetrical slots can be shared and only need to be installed in reverse, thereby reducing the number of accessories.

[0028] The slots of the air guide plate slots 4 merge with each other at the side away from the end surface of the side plate 1, so that each slot provides a different angle, that is, the air guide plate 3 provides different directions when installed in different slots, resulting in different sizes.

[0029] In order to simplify the installation difficulty, a positioning groove 6 or a positioning column is provided at the junction of the slots of the air guide plate 4, and a positioning column or a positioning groove 6 is provided at the corresponding position of the air guide plate 3. The positioning column and the positioning groove 6 provide a fool-proof effect and simplify the installation difficulty.

[0030] like Figure 5 and Figure 6 As shown, the air guide plate 3 can be a flat plate, and the side of the air guide plate 3 facing away from the air guide bend plate 2 is flush with the end face of the side plate 1. The air guide plate 3 is set as a flat plate to reduce the production cost. When the slots of the air guide plate slot 4 are set to an odd number, the air guide plate 3 connected to the middle slot is preferably a flat plate, providing an extension of the air guide bend plate 2 and the air guide plate 9, wherein the side of the air guide plate 3 facing away from the air guide bend plate 2 and the air guide plate 9 is flush with the end face of the side plate 1, ensuring that the end of the air outlet is flat, which is convenient for docking of the equipment.

[0031] The air guide plate 3 includes an inclined portion close to the air guide curved plate 2 or the air guide plate 9 and a straight portion connected to the inclined portion. The straight portion is flush with and perpendicular to the end face of the side plate 1. The inclined portion is provided to adjust the distance between the two ends of the air outlet. The straight portion is connected to one side of the inclined portion, and the straight portion is perpendicular to the end face, which simplifies the difficulty of docking. The straight portion is flush with the end face of the side plate 1, ensuring that the end of the air outlet is flat, which is convenient for docking of equipment.

[0032] The wind guide bend plate 2 and the wind guide plate 9 are detachably connected to the side panel 1, and an wind guide plate slot 5 or a block is provided on the side panel 1, or on the wind guide bend plate 2 and the wind guide plate 9. Corresponding snap-fit ​​blocks or wind guide plate slots 5 are provided on the wind guide bend plate 2 and the wind guide plate 9, or on the side panel 1. In the present embodiment, the wind guide bend plate 2, the wind guide plate 9 and the side panel 1 are detachably connected, which is convenient for the transportation and storage of the entire air outlet. When the wind guide plate slot 5 is provided on the side panel 1, the side edge of the wind guide bend plate 2 or the wind guide plate 9 is directly snapped into the wind guide plate slot 5 as a block, and there is no need to make the block separately, thereby further reducing the cost.

[0033] The air guide plate slot 4 is arranged on the air guide plate 3, the side panel 1, the air guide bend plate 2 or the air guide plate 9. Preferably, the air guide plate slot 4 is arranged on the side panel 1. Specifically, when the air guide plate slot 4 is arranged on the air guide plate 3, it can be arranged close to both sides of the side panel 1, or it can be arranged close to the air guide bend plate 2 or one side of the air guide plate 9. When it is arranged on both sides of the side panel 1, a card block that engages with it is arranged at the corresponding position of the side panel 1; when the air guide plate slot 4 is arranged on the air guide bend plate 2 or the air guide plate 9, the air guide plate 3 is directly engaged with it.

[0034] The wind guide bend plate 2 or the wind guide plate 9 is provided with a protrusion 7 and a protrusion clamping portion 8 on the side opposite to the wind guide vane 3. In the present embodiment, the wind guide vane slot 4 is provided on both sides of the side plate 1 or the wind guide vane 3 close to the side plate 1, wherein the cross-section of the protrusion 7 may be cylindrical, elliptical or multi-prism-shaped, and the cross-section of the protrusion clamping portion 8 may be a polygon for partially clamping the protrusion 7, a C-shaped slot with an opening or other shape that can clamp the protrusion 7, which facilitates the sealing effect of the connection between the wind guide bend plate 2 and the wind guide vane 3, makes the wind guide vane 3 tightly connected to the wind guide bend plate 2, improves practicality, and improves the overall structural strength at the same time. In addition, the protrusion 7 may be provided on the wind guide bend plate 2 or the wind guide plate 9, or on the wind guide vane 3, and the protrusion clamping portion 8 is relatively provided on the wind guide vane 3 or on the wind guide bend plate 2 or the wind guide plate 9.

[0035] Preferably, the protrusion 7 is cylindrical, and the protrusion clamping part 8 is a C-shaped slot that cooperates with the cylindrical shape. The opening size of the C-shaped slot is smaller than the diameter of the cylindrical protrusion 7. The protrusion 7 and the protrusion clamping part 8 are respectively set to be cylindrical and C-shaped slots with openings, and the protrusion 7 and the protrusion clamping part 8 can rotate relative to each other, that is, they can be rotated and adjusted according to the installation angle of the air guide plate 3, thereby simplifying the installation difficulty. The opening size of the C-shaped slot is smaller than the diameter of the cylindrical protrusion 7, which can prevent the protrusion 7 and the protrusion clamping part 8 from detaching after installation. At the same time, the transition at the air outlet is smooth to reduce wind resistance. In this embodiment, the protrusion 7 is limited to sliding and rotating along the axis of the protrusion clamping part 8. During installation, the air guide plate 3 is first slid into the air guide bent plate 2 or the air guide plate 9, and then the side plate 1 is fixedly installed. That is, the air guide plate 3 is doubly limited by the air guide plate slot 4, the protrusion 7 and the protrusion clamping part 8, which greatly improves the fixing effect.

[0036] like Figure 3 As described, the outer wall of the raised portion 7 cooperates with the inner wall of the raised clamping portion 8. In order to reduce material usage and reduce weight, in this embodiment, the cylindrical raised portion 7 can also be concentrically provided with a weight-reducing through groove, wherein the raised portion 7 and the raised clamping portion 8 can be designed as a clearance fit, a transition fit or an interference fit as needed. The clearance fit facilitates installation and angle adjustment, and the interference fit makes the structure more stable after installation.

[0037] like Figure 4 The diameter of the raised portion 7 is smaller than the inner wall of the raised clamping portion 8, and a protrusion 701 is extended from one side of the raised portion 7, and the protrusion 701 contacts the inner wall of the raised clamping portion 8. Specifically, the side of the protrusion 701 in contact with the C-shaped slot is set as an arc surface for easy sliding, and the diameter of the arc surface is consistent with the diameter of the inner wall of the C-shaped slot. In this embodiment, the raised portion 7 uses less material, which can save costs, and is easy to assemble and stable to combine.
