Description

Technical Field

[0001] The utility model relates to the technical field of ventilation components, and more specifically, to an air outlet mechanism of a central air conditioner. Background Art

[0002] The central air conditioning system is an air conditioning system commonly found in various indoor environments. It is generally composed of one or more cold and heat source systems and multiple air conditioning systems. It can use liquid vaporization to cool down to offset the heat load of the indoor environment, or it can use the heating system to provide the required heat for the air conditioning system. Through the coordination of the cold and heat source systems, the central air conditioning system can maintain the stability of the indoor temperature.

[0003] When operators are installing a central air-conditioning system, they often use an air outlet mechanism to evenly supply air to the room. In actual use, although the existing air outlet mechanism has a basic even air supply function, after the central air-conditioning system has been running for a long time, a large amount of dust will adhere to the surface of the air guide blades of the air outlet mechanism, reducing the indoor air quality. In addition, since the air outlet mechanism is generally fixed at the ceiling, the operator must use additional equipment such as a ladder to clean the air outlet mechanism, which greatly increases the difficulty of cleaning for the operator, and therefore it needs to be improved. Utility Model Content

[0004] In order to overcome the deficiencies of the prior art, the utility model provides an air outlet mechanism for a central air conditioner, which has the advantage of being easy to clean dust.

[0007] A protective cover, the protective cover is fixedly connected to the rear side of the upper surface of the fixing plate, and the bottom end of the protective cover passes through the fixing plate and extends to the bottom of the fixing plate;

[0008] A cleaning mechanism, the cleaning mechanism being arranged on the outer surface of the fixing plate;

[0009] Among them, the cleaning mechanism includes a motor, which is fixedly installed inside the protective cover, and the other end of the motor output shaft is fixedly sleeved with a driving shaft, the bottom end of the driving shaft passes through the protective cover and extends to the bottom of the protective cover, the outer surface of the driving shaft is fixedly sleeved with an active rod, the other end of the active rod is hinged with a driven rod, the other end of the driven rod is hinged with a mounting plate, the middle part of the lower surface of the mounting plate is fixedly connected with a cleaning brush, the lower surface of the cleaning brush and the outer surface of the fixed plate are movably connected, and the active rod rotates to make the driven rod drive the mounting plate to move forward as a whole.

[0013] As a preferred technical solution of the utility model, the outer surfaces of the two movable connecting pieces are fixedly connected with a baffle located above the hollow plate, and the lower surface of the baffle is movably connected to the upper surface of the hollow plate.

[0017] 1. The utility model is provided with an active rod, a driven rod, a mounting plate, a cleaning brush and a limit sleeve. When the motor is running, the active shaft and the active rod will start to rotate, and the driven rod will start to rotate with the other end of the active rod as the axis under the drive of the active rod.

At this time, the hollow plate as a whole will break away from the inside of the fixed plate under the action of gravity, which realizes the rapid disassembly and assembly function of the hollow plate as a whole and greatly improves the speed at which the operator replaces the hollow plate as a whole.

DETAILED DESCRIPTION

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] like Figures 1 to 6 As shown, the utility model provides a central air-conditioning outlet mechanism, comprising:

[0028] A fixed plate 1, the inner surface of which is movably connected to a hollow plate 2, and the inner surface of which is fixedly connected to an air guide vane 18;

[0029] The protective cover 3 is fixedly connected to the rear side of the upper surface of the fixing plate 1, and the bottom end of the protective cover 3 passes through the fixing plate 1 and extends to the bottom of the fixing plate 1;

[0030] A cleaning mechanism, the cleaning mechanism is arranged on the outer surface of the fixed plate 1;

[0031] Among them, the cleaning mechanism includes a motor 4, which is fixedly installed inside the protective cover 3, and the other end of the output shaft of the motor 4 is fixedly sleeved with a driving shaft 5, the bottom end of the driving shaft 5 passes through the protective cover 3 and extends to the bottom of the protective cover 3, and the outer surface of the driving shaft 5 is fixedly sleeved with an active rod 6, and the other end of the active rod 6 is hinged with a driven rod 7, and the other end of the driven rod 7 is hinged with a mounting plate 8, and a cleaning brush 9 is fixedly connected to the middle of the lower surface of the mounting plate 8, and the lower surface of the cleaning brush 9 is movably connected to the outer surface of the fixed plate 1, and the rotation of the active rod 6 causes the driven rod 7 to drive the mounting plate 8 to move forward as a whole.

[0032] When the motor 4 is running, the active shaft 5 and the active rod 6 will start to rotate. At this time, the other end of the active rod 6 will drive the driven rod 7 to make the driven rod 7 start to rotate. At the same time, the other end of the driven rod 7 will drive the mounting plate 8 to make the mounting plate 8 start to move as a whole.

[0033] Among them, the left and right sides of the lower surface of the mounting plate 8 are fixedly connected to the limiting blocks 10, the outer surface of the limiting blocks 10 is movably connected to the limiting sleeve 11, and the lower surface of the limiting sleeve 11 is fixedly connected to the upper surface of the fixing plate 1.

[0034] The design of the limiting block 10 and the limiting sleeve 11 ensures the stability of the entire mounting plate 8 when it moves forward and backward.

[0035] There are movable grooves 12 on both sides of the upper surface of the hollow plate 2. The inner surface of the movable groove 12 is movably connected with a movable connecting piece 13. There are two movable connecting pieces 13, and the two movable connecting pieces 13 have the same size.

[0036] The movable connecting piece 13 can move left and right along the inner surface of the movable groove 12 .

[0037] Among them, the left and right sides of the upper surface of the hollow plate 2 are fixedly connected with fixing plates 14, and the outer surface of the fixing plate 14 is fixedly connected with springs 15. There are two springs 15, and the other ends of the two springs 15 are fixedly connected to the outer surfaces of the two movable connecting plates 13 respectively.

[0038] The design of the spring 15 enables the movable connecting piece 13 as a whole to automatically reset under the elastic force of the spring 15 .

[0039] The outer surfaces of the two movable connecting pieces 13 are fixedly connected to a baffle plate 17 located above the hollow plate 2 , and the lower surface of the baffle plate 17 is movably connected to the upper surface of the hollow plate 2 .

[0040] The baffle 17 can block the movable groove 12 to ensure that the airflow does not pass through the movable groove 12 .

[0041] Among them, the front and rear sides of the upper surface of the hollow plate 2 are fixedly connected with movable grooves 12, the outer surface of the movable groove 12 is movably connected to a limiting frame 19, and the lower surface of the limiting frame 19 is fixedly connected to the upper surface of the fixed plate 1.

[0042] The design of the limiting frame 19 has a limiting effect on the hollow plate 2 as a whole.

[0043] The tops of the outer surfaces of the two movable connecting pieces 13 are fixedly connected with locking blocks 16 located above the fixing plate 1 , and the lower surfaces of the locking blocks 16 are movably connected to the upper surface of the fixing plate 1 .

[0044] When the locking block 16 contacts the upper surface of the fixing plate 1 , the entire hollow plate 2 will be fixed inside the fixing plate 1 under the combined action of the locking block 16 and the limiting frame 19 .

[0045] The working principle and use process of this utility model:

[0046] First, the operator fixes the fixing plate 1 as a whole on the indoor ceiling position. When dust adheres to the outer surface of the air guide blade 18, the operator starts the motor 4. As the motor 4 runs, the driving shaft 5 and the driving rod 6 begin to rotate. At the same time, the driven rod 7 begins to rotate with the other end of the driving rod 6 as the axis, and the other end of the driven rod 7 drives the mounting plate 8, so that the mounting plate 8 and the cleaning brush 9 begin to move forward under the common limit of the limit block 10 and the limit sleeve 11. During the movement of the cleaning brush 9, the cleaning brush 9 cleans the dust on the outer surface of the air guide blade 18, thereby ensuring that when the airflow passes through the air guide blade 18 and enters the room, there is no large amount of dust mixed in the gas.

[0047] When the operator needs to replace the air guide blades 18, the operator pulls the two movable connecting plates 13, so that the two movable connecting plates 13 begin to move toward each other along the inner surface of the movable groove 12. Finally, as the two movable connecting plates 13 move as a whole, the two locking blocks 16 will break away from the contact with the upper surface of the fixed plate 1, which releases the locking blocks 16 from fixing the hollow plate 2 as a whole. As a result, the operator can directly remove the hollow plate 2 as a whole from the interior of the fixed plate 1, which greatly simplifies the replacement process of the hollow plate 2 and the air guide blades 18 and provides convenience for the operator to replace the hollow plate 2 and the air guide blades 18.
