Description

Technical Field

[0001] The utility model relates to the field of fresh air equipment, and more specifically, to an intelligently controllable floor air supply valve and a floor air supply air conditioning system. Background Art

[0002] As people's requirements for residential air quality increase, more and more people are choosing to install fresh air systems. Fresh air systems filter and purify outdoor fresh air through a main unit before delivering it indoors. At the same time, they discharge indoor polluted air to the outside through an exhaust vent and recover the energy in the polluted air, providing high-quality indoor air while saving energy. Among them, the floor-supply and top-return ventilation method has been widely used in fresh air systems due to its advantages such as good ventilation efficiency, reduced floor height, and convenient construction. During the floor-supply process, floor-supply air valves are often installed to balance the air volume of each branch. Existing floor-supply air valves often adjust the air volume manually and cannot adjust the air volume automatically, which limits the possibility of linking the floor-supply air system with other electrical appliances. For example, the utility model patent with announcement number CN211423409U discloses a floor air volume control valve, comprising a valve body, a regulating plate, and a rotating column for controlling the rotational direction of the regulating plate. The regulating plate is rotatably mounted within the inner cavity of the valve body via the rotating column. The rotating column extends through the regulating plate and is supported between the upper and lower surfaces of the valve body. When the rotating column rotates, the regulating plate rotates. In the above technical solution, the rotating column needs to be rotated manually, which cannot achieve automatic adjustment of the floor air volume, nor can it achieve linkage between the floor air supply system and other electrical appliances.

[0041] A pair of end plates, comprising a first end plate 3 and a second end plate 5 arranged in parallel in the air duct 1;

[0046] In one of the technical solutions, the synchronous drive assembly includes:

[0050] Among them, the synchronization rod base 11 is movably connected to the connecting piece 12, and the connecting piece 12 is provided with a long slot 13. The side of the synchronization rod base 11 close to the connecting piece 12 is provided with a movable column 14 extending into the long slot 13. The movable column 14 is limited in the long slot 13 in the width direction of the long slot 13.

In order not to affect the swing of the blades, any end plate has a certain distance from the inner wall of the air duct, and the platform is provided with a plurality of grooves that cooperate with the movement of a plurality of connecting plates 12.

[0054] In one of the technical solutions, an implementation structure of the detachable connection between the grid plate and the air duct 1 is as follows: a pair of clamping plates are provided at the bottom of the grid plate, which are just clamped on the air duct 1, and a socket is formed by the pair of clamping plates.
