Description

Technical Field

[0001] The present application relates to the technical field of air duct structures, and more specifically, to an air duct structure for a central air conditioner. Background Art

[0002] The main function of the air duct of the air conditioner is to transfer air and send the cold and hot air produced by the outdoor unit to the indoor unit. In summer, the outdoor unit will inhale the hot air and produce cold air after compression. The outdoor unit will inhale the low-temperature air and produce hot air after compression.

[0003] The document with the prior art publication number CN220229512U provides an air duct structure of a central air conditioner. When in use, a fixing ring is provided to facilitate the installation of the air duct. By providing a first mounting plate, a second mounting plate and a mounting hole, the air duct and the connecting pipe can be fixed with bolts. By providing a sleeve, a rubber sleeve and a sealing rubber pad, the softness of the rubber can be used to block the gap at the connection between the sleeve and the connecting pipe to prevent air leakage, thereby improving the working efficiency of the central air conditioner. By providing an installation groove, a limit frame, a rubber ring, a wind shield cover and bolts, the wind shield cover can be easily removed as needed, and the side of the air duct is connected to the branch pipe. When not in use, the wind shield cover is fixed to the air duct by bolts, and the rubber ring can block the gap between the wind shield cover and the air duct connection to prevent air leakage, thereby effectively enhancing the practicality of the device.

[0004] Although the device has many beneficial effects, the following problems still exist: during the use of the air duct, in order to reduce noise, a sound insulation pad is often glued to the outside of the air duct with glue, and the sound insulation pad is difficult to reinforce after long-term use, which makes the sound insulation pad very easy to warp or fall off, which can easily affect the sound insulation effect of the air duct. In view of this, we propose an air duct structure for a central air conditioner. Utility Model Content

[0005] The embodiment of the present application provides an air duct structure for a central air conditioner, thereby solving the technical problem in the prior art that it is difficult to reinforce the sound insulation pad after long-term use, which makes the sound insulation pad very easy to warp or fall off, thereby easily affecting the sound insulation effect of the air duct. The embodiment of the present application facilitates the staff to abut and reinforce the boundaries of the sound insulation pad that has been used for a long time, thereby preventing the sound insulation pad from warping or falling off after long-term use, thereby facilitating the technical effect of ensuring the sound insulation effect of the air duct body.

[0006] The embodiment of the present application provides an air duct structure of a central air conditioner, comprising: an air duct body;

[0007] The outer sides of both ends of the air duct body are fixedly sleeved with mounting rings, and the four sides of the air duct body are bonded with sound insulation pads for reducing noise;

[0028] The present application is further described in detail below in conjunction with the accompanying drawings.

[0029] Reference Figure 1 and Figure 2 The embodiment of the present application discloses an air duct structure of a central air conditioner. The air duct structure of the central air conditioner comprises: an air duct body 1;

[0030] The outer sides of both ends of the air duct body 1 are fixedly sleeved with mounting rings 2, and the four sides of the air duct body 1 are bonded with sound insulation pads 4 for reducing noise;

[0031] Anti-drop mechanisms 3 are provided at the top and bottom of both sides of the air duct body 1 to reinforce the sound insulation pad 4;

[0032] The anti-slip mechanism 3 includes a support frame 31, which is fixedly connected to the mounting ring 2. A support plate 33 is elastically connected to the inner side of the support frame 31, and a reinforcing plate 34 is fixedly connected to the bottom of the support plate 33 for abutting the boundary of the sound insulation pad 4, thereby preventing the sound insulation pad 4 from falling off due to long-term use and ensuring the sound insulation effect of the air duct body 1.

[0033] Reference Figure 2 and Figure 3 Openings are provided on both sides of the top of the support frame 31, and a slide rod 32 is slidably connected in the opening. The bottom end of the slide rod 32 is fixedly connected to the top of the support plate 33, so that the support plate 33 and the reinforcement plate 34 can move along the length direction of the slide rod 32.

[0034] Reference Figure 2 and Figure 3 The top ends of the two slide bars 32 are fixedly connected with a pull plate 36, which is convenient for the staff to pull the slide bars 32 and also convenient for preventing the slide bars 32 from escaping from the opening.

[0035] Reference Figure 2 and Figure 3 A spring 35 is fixedly connected to one side of the support plate 33 close to the slide rod 32. The spring 35 is fixedly connected to the top of the inner wall of the support frame 31, and the spring 35 is sleeved on the outside of the slide rod 32 to prevent the support plate 33 and the reinforcement plate 34 from moving at will.

[0036] Reference Figure 1 The support frame 31 is inclined, and the cross-section of the reinforcement plate 34 is L-shaped, so that the reinforcement plate 34 can abut and reinforce the connection between two adjacent sound insulation pads 4.

[0037] Reference Figure 3 A plurality of through holes are provided on one side of the mounting ring 2, so that the staff can connect the mounting ring 2 to the central air conditioner through external bolts.

[0038] Reference Figure 2A first slide groove 5 and a second slide groove 6 are respectively provided on both sides of the top of the support frame 31. A slider 9 is slidably connected in the first slide groove 5, and a baffle 7 is fixedly connected to the top of the slider 9 for the staff to support the pull plate 36.

[0039] Reference Figure 1 The cross sections of the first slide groove 5, the second slide groove 6 and the slider 9 are all in a convex shape, thereby preventing the slider 9 from falling.

[0040] Reference Figure 3 A magnetic block 8 is fixedly connected to one side of the first slide groove 5 and the second slide groove 6, and the slider 9 is magnetically attracted to the magnetic block 8, thereby preventing the slider 9 and the baffle 7 from moving at will.

[0041] The implementation principle of the air duct structure of a central air conditioner in the embodiment of the present application is as follows: when the staff needs to bond the sound insulation pad 4, they can pull the pull plate 36 to drive the slide bar 32 to move, and the movement of the slide bar 32 can drive the support plate 33 to move and squeeze the spring 35, and the movement of the support plate 33 can drive the reinforcement plate 34 to move, so that the reinforcement plate 34 is separated from the air duct body 1, and then the staff can move the slider 9 out of the first slide groove 5 and insert the slider 9 into the inner side of the second slide groove 6, so as to support the pull plate 36 with the baffle plate 7, so that the spring 3 5 keeps the squeezed state without rebounding. Then, the staff can use glue to glue the four sound insulation pads 4 to the four sides of the air duct body 1 respectively. Then, the staff can pull the pull plate 36 to take the baffle 7 and the slider 9 out of the second slide groove 6, and release the pull plate 36 to make the squeezed spring 35 return to the original state and rebound, so that the support plate 33 and the reinforcement plate 34 move toward the direction of the air duct body 1, so as to use the reinforcement plate 34 to abut and reinforce the sound insulation pad 4, so as to prevent the sound insulation pad 4 from warping or falling off after long-term use.

[0042] The embodiment of the present application provides an air duct structure for a central air conditioner. By setting a reinforcement mechanism 3, it is convenient for the staff to abut and reinforce the boundary of the sound insulation pad 4 that is used for a long time, so as to prevent the sound insulation pad 4 from curling or falling off after long-term use, thereby ensuring the sound insulation effect of the air duct body 1.
