Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of air volume regulation, and more particularly to an air outlet cover plate and an air outlet assembly. BACKGROUND

[0002] When the air outlet of a split air conditioner, a fan coil, etc. is at a low temperature and a high wind speed, the airflow directly blows at a fast speed to the human body, and the temperature difference between the cold air and the human body is large, which causes poor thermal comfort.

[0003] At present, it is difficult to avoid the problem of poor thermal comfort, but the thermal comfort can be improved by controlling the wind speed. For a split air conditioner, the wind speed is controlled by using a fan frequency conversion. If the wind speed at the pipe opening of a floor air supply pipe is reduced, more floor air supply pipes need to be arranged to ensure the air supply volume, which affects the cost and construction period. For a fan coil, the temperature of the low-temperature coil is increased to reduce the cooling effect, which inevitably requires increasing the fan coil, causing unnecessary waste.

[0004] Therefore, an air outlet cover plate and an air outlet assembly are needed to solve the above problems. CONTENT OF THE INVENTION

[0008] A flexible side wing comprises a first connecting end and a second connecting end, which are respectively connected to the cover plate body and the pipe opening; when the cover plate body rotates around the pipe opening, the flexible side wing can cover the gap between the cover plate body and the pipe opening; a plurality of evenly distributed ventilation holes are arranged on the flexible side wing;

[0009] A support member can provide support for the cover plate body when the cover plate body rotates around the pipe opening.

[0010] Optionally, the cover plate body comprises a frame and a plurality of partitions uniformly distributed in the frame, the hinge end and the connecting end are respectively arranged at opposite ends of the frame, and gaps between the partitions and the frame and gaps between adjacent partitions form the ventilation channel.

[0014] Optionally, the flexible part is provided with a sound-absorbing layer.

[0016] The application also provides a tuyere assembly, comprising a ventilation pipe and a tuyere cover plate as described above, and the tuyere cover plate is hingedly connected to the pipe opening of the ventilation pipe.

[0017] Optionally, the tuyere cover plate comprises a cover plate body, a flexible side wing and a support, when the cover plate body is fastened to the pipe opening, airflow flows through the ventilation channel of the cover plate body, and when the cover plate body rotates around the pipe opening, the support supports the cover plate body, and airflow flows through the ventilation channel of the cover plate body and the ventilation holes of the flexible side wing.

[0018] In addition, optionally, a plurality of uniformly distributed flow guide cones are arranged at least partially in the ventilation pipe.

The flexible side wing can provide a flow splitting effect, and while the gas flow rate remains unchanged, the flow rate can be reduced. By simultaneously adjusting the airflow direction and the airflow speed, the airflow is prevented from blowing rapidly towards the human body, thereby improving thermal comfort.

Figure 2 A schematic diagram of the cover plate body of the air port cover plate. Figure 1 A schematic diagram of the flexible side wing of the air port cover plate. As shown in Figure 3 Figure 1 The air port cover plate includes a cover plate body 1, a flexible side wing 2 and a support piece 3.

The cover plate body 1 is provided with a plurality of evenly distributed ventilation channels. When the cover plate body 1 covers the pipe opening of the vent pipe 10, airflow can flow through the ventilation channels. The connecting end can be connected with the vent to make the cover plate body 1 relatively stably connected to the vent pipe 10, avoiding misoperation.

[0032] The flexible side wing 2 comprises a first connecting end and a second connecting end, which are connected to the cover plate body 1 and the pipe opening respectively. The flexible side wing 2 can be set according to the gap shape between the cover plate body 1 and the vent pipe 10 when the cover plate body 1 is rotated to the maximum angle, usually in a symmetrical strip structure, with a larger width in the middle and a smaller width closer to the edge. The first connecting end and the second connecting end are respectively arranged at the top and the bottom of the flexible side wing 2, and the first connecting end can also be arranged at both ends of the flexible side wing 2.

[0033] The connecting end of the cover plate body 1 is separated from the vent pipe 10, and when the cover plate body 1 rotates around the pipe opening, the flexible side wing 2 can cover the gap between the cover plate body 1 and the pipe opening. The flexible side wing 2 is made of flexible material and can be folded or unfolded, and the flexible side wing 2 opens and closes correspondingly with the rotation of the cover plate body 1.

When the cover plate body 1 is buckled on the pipe opening, the flexible side wing 2 is folded, for example, below the cover plate body 1, and airflow flows through the ventilation channels only. When the cover plate body 1 rotates around the pipe opening, under the joint action of airflow blowing and the cover plate body 1 stretching, the flexible side wing 2 unfolds from the gap between the cover plate body 1 and the pipe opening, and can cover the gap between the cover plate body 1 and the pipe opening, and airflow flows through the ventilation channels and the ventilation holes.

When the cover plate body 1 and the flexible side wing 2 jointly act, by rotating the cover plate body 1, the airflow direction can be adjusted, the selectivity of the airflow direction is increased, and direct blowing is avoided. The flexible side wing 2 can provide a flow splitting effect, and the flow rate can be reduced while the gas flow remains unchanged. By simultaneously adjusting the airflow direction and the airflow speed, the airflow is prevented from blowing rapidly to the human body, thereby improving the thermal comfort.

By adjusting the angle and position of the partition, the gap between the partition and the frame and the gap between adjacent partitions can be adjusted, that is, the ventilation area and the ventilation angle of the ventilation channel are adjusted, and then the wind power and the wind direction are adjusted. The cover plate body 1 can freely select the ventilation angle and the ventilation area, can further adjust the wind power and the wind direction, realizes multi-directional air supply, improves the comfort, and meets more personalized needs.

[0040] In an embodiment of the present application, the partition includes but is not limited to a transverse partition and / or a longitudinal partition, a plurality of transverse partitions and a plurality of longitudinal partitions are arranged in the frame in a staggered manner, and the ends of the transverse partitions and the longitudinal partitions are rotatably connected on the frame. The plurality of transverse partitions can be connected together by a connecting rod, and the plurality of longitudinal partitions can be connected together by a connecting rod.

[0041] Optionally, the flexible side wing 2 comprises an elastic frame and a flexible part arranged in the elastic frame, the first connecting end and the second connecting end are arranged on the elastic frame, and the ventilation holes are uniformly distributed on the flexible part.
