[0001] The utility model relates to the field of air conditioning, in particular to a central air conditioning air blowing reversing device. Background Art

[0002] The central air-conditioning system consists of one or more cold and heat source systems and multiple air conditioning systems. It uses the principle of liquid vaporization refrigeration to provide the required cooling capacity for the air conditioning system to offset the heat load of the indoor environment; the heating system provides the required heat for the air conditioning system to offset the cooling and heating loads of the indoor environment; the air conditioning air guide plate is an air guide component installed at the air outlet of the air conditioner to change the airflow direction of the air outlet of the air conditioner.

[0003] Central air conditioners generally change the direction of the air duct through air guide plates, but traditional air guide plates are generally fixed in angle. When the air guide plates are lowered, the hot and cold air will flow in one direction under the obstruction of the air guide plates, causing the hot and cold air to diffuse from one place, reducing the diffusion efficiency of the hot and cold air and increasing the time for adjusting the temperature difference in the room. Therefore, a central air conditioner blowing reversing device is proposed to solve the above problem. Utility Model Content

When the air guide plate is lowered, the cold and hot air will flow in one direction under the obstruction of the air guide plate, so that the cold and hot air are diffused from one place, which reduces the diffusion efficiency of the cold and hot air and increases the time for adjusting the temperature difference in the room.

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] In the embodiment, Figure 1-4A central air-conditioning blowing reversing device is provided. The utility model comprises a central air-conditioning main body 1, a vent is opened inside the central air-conditioning main body 1, a mounting plate 2 is fixedly connected inside the vent, a motor 3 is fixedly connected inside the central air-conditioning main body 1, a first air guide plate 4 rotatably connected to the inside of the vent is fixedly connected to the outer side of the output shaft of the motor 3, a first rotating shaft 5 rotatably connected to the inside of the mounting plate 2 is fixedly connected to the outer side of the first air guide plate 4, a first gear 6 is fixedly connected to the outer side of the first rotating shaft 5, a partition plate 7 is fixedly connected to the inside of the mounting plate 2, a second rotating shaft 8 is rotatably connected to the inside of the partition plate 7, a second gear 10 meshing with the first gear 6 is fixedly connected to the outer side of the second rotating shaft 8, a transmission device 9 is arranged on the outer side of the second rotating shaft 8, a second air guide plate 11 rotatably connected to the inside of the vent is fixedly connected to the outer side of the transmission device 9.

[0028] The vent includes a first ventilation slot and a second ventilation slot, the first ventilation slot and the second ventilation slot are separated by a mounting plate 2, the first air guide plate 4 is located inside the first ventilation slot, and the second air guide plate 11 is located inside the second ventilation slot.

[0029] The first air guide plate 4 and the second air guide plate 11 respectively cover and open the two ventilation slots, so that the cold and hot air are blown away separately.

[0030] The first gear 6 , the second gear 10 and the transmission device 9 are all located inside the mounting plate 2 , and the first gear 6 and the second gear 10 are separated from the transmission device 9 by a partition plate 7 .

[0031] The mounting plate 2 provides a movable space for the gears and the transmission wheel, and the rotation of the first gear 6 will cause the transmission device 9 on the right side of the partition plate 7 to operate.

[0032] The transmission device 9 includes a first transmission wheel 91 fixedly connected to the outer side of the second rotating shaft 8, a third rotating shaft 92 is rotatably connected inside the partition plate 7, and a second transmission wheel 93 is fixedly connected to the outer side of the third rotating shaft 92 and connected to the first transmission wheel 91 through a transmission belt.

[0033] The rotation of the second rotating shaft 8 drives the first transmission wheel 91 to rotate, and under the action of the transmission belt, the second transmission wheel 93 rotates, and the third rotating shaft 92 rotates.

[0034] The third rotation axis 92 penetrates and extends to the outside of the mounting plate 2 , and the first rotation axis 5 and the third rotation axis 92 are located in the same horizontal plane.

[0035] When the third rotating shaft 92 rotates, it drives the second air guide plate 11 outside the third rotating shaft 92 to rotate in the second ventilation slot, thereby controlling the opening and closing of the air duct.

[0036] The diameter of the second gear 10 is greater than the diameter of the first gear 6 , and the diameters of the first transmission wheel 91 and the second transmission wheel 93 are the same.

[0037] The first rotating shaft 5 rotates the first air guide plate 4. Under the action of the second gear 10, the first rotating shaft 5 has different rotation angles from the third rotating shaft 92 and the second rotating shaft 8, so that the rotation angles of the two air guide plates are different.

[0038] Working principle:

[0039] When the central air conditioner is started, the motor 3 will drive the first air guide plate 4 to rotate, so that the first air guide plate 4 is opened. The rotation of the first air guide plate 4 will cause the first rotating shaft 5 to rotate, and under the action of the first gear 6, the second gear 10 meshing therewith will also rotate. Since the diameter of the second gear 10 is larger than the first gear 6, the rotation angle of the second gear 10 is smaller than the first gear 6. The rotation of the second gear 10 causes the second rotating shaft 8 to rotate, and under the action of the two transmission wheels, the third rotating shaft 92 is rotated, thereby rotating the second air guide plate 11. The opening and closing angles of the second air guide plate 11 and the first air guide plate 4 are different, so that the two air guide plates can present two different angles.
