Description

Technical Field

[0001] The utility model relates to the technical field of ventilation accessories, in particular to a drum-shaped air outlet for building ventilation. Background Technique

[0002] The drum-shaped air outlet is a special air flow component, the design of which is aimed at optimizing air flow, improving the efficiency of the air conditioning system and the indoor environmental quality. It is an air outlet device that ejects air at a relatively large angle. The drum-shaped air outlet usually consists of an outer frame and an inner liner. After the outer frame is fixed, the inner liner part can rotate up and down by a certain angle to adjust the air supply angle. At the same time, the guide vanes can adjust the air flow angle blown left and right, further enhancing the flexibility and uniformity of the air supply.

[0003] At present, the drum-shaped air outlet is used in the internal ventilation of buildings. When the drum-shaped air outlet is in use, it is usually used in cooperation with the air supply mechanism. The connection between the drum-shaped air outlet and the air supply mechanism is mostly through pipeline connection. When the pipeline delivers the wind force to the air outlet, most of the wind force gathers near the pipeline position, that is, most of the wind force of the traditional drum-shaped air outlet goes out from the middle position, which makes the air output on both sides of the drum-shaped air outlet smaller, and further affects the air output range and the air supply uniformity of the air outlet.

[0018] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts shall fall within the protection scope of the present utility model.

[0019] Please refer to Figures 1-4As shown in the figure, a drum-shaped air outlet for building ventilation includes a connecting air duct 1 connected to a air supply duct. The other end of the connecting air duct 1 communicates with a connecting shell 2, and the other end of the connecting shell 2 communicates with a housing 3. The housing 3 is bolted to the building air outlet part. An air outlet hood 5 is rotatably arranged in the inner cavity of the housing 3. On one side of the surface of the housing 3, a driving mechanism body 4 for controlling the working direction of the air outlet hood 5 is fixed. A plurality of air distribution blocks 6 for controlling the wind direction are fixed in the inner cavity of the connecting shell 2. A guiding mechanism 7 for making the air outlet uniform is arranged in the inner cavity of the connecting air duct 1.

[0020] In the normal use of the air outlet hood 5 of the present utility model, the guiding mechanism 7 can be made to work. Then, under the action of the guiding mechanism 7, the wind force can be guided, so that the wind force acts on different positions of the air outlet hood 5, thereby improving the air outlet range of the air outlet hood 5 and the uniformity of the wind force acting on the surface of the air outlet hood 5. In addition, under the action of the air distribution blocks 6, the wind force can be further divided in advance, which can also improve the uniformity of the air outlet of the air outlet hood 5.

[0021] The number of the air distribution blocks 6 is an even number, and they are arranged in the inner cavity of the connecting shell 2 in an equally divided and equidistant manner. In this embodiment, through this setting, a plurality of air distribution blocks 6 can be evenly distributed in the inner cavity of the connecting shell 2, and the sizes of the divided areas in the inner cavity of the connecting shell 2 can be made basically the same.

[0022] The inclination directions of a plurality of air distribution blocks 6 are the same, and the inclination angles gradually increase. In this embodiment, through this setting, a uniformly divided air supply area is formed on both sides in the inner cavity of the connecting shell 2, and under the setting of the inclination angles of the air distribution blocks 6, the wind can be better flowed, making the air outlet of the air outlet hood 5 more uniform.

[0023] The guiding mechanism 7 includes a plurality of fixing rods 71 fixed in the inner cavity of the connecting air duct 1. The other end of the fixing rod 71 is rotatably provided with a rotating rod 72, and a wind direction guiding block 73 is fixed on the surface of the rotating rod 72. In this embodiment, through the setting of the fixing rod 71, the rotating rod 72 and the wind direction guiding block 73, the rotating rod 72 and the wind direction guiding block 73 can rotate under the limitation of the fixing rod 71.

[0024] A plurality of fixing rods 71 are arranged in a circular array in the inner cavity of the connecting air duct 1, and three are in a group. In this embodiment, through this setting, the excessive fixing rods 71 are prevented from hindering the passage of the wind force in the connecting air duct 1, and the wind force passing ability of the connecting air duct 1 is improved.

[0025] The bottom end of the wind direction guiding block 73 is lower than the connection part of the connecting air duct 1 and the connecting shell 2. In this embodiment, through this setting, it is convenient for the wind force to pass through the wind direction guiding block 73, so that there is more passing space between the wind direction guiding block 73 and the connecting air duct 1.

[0026] Working principle: In daily use, with the connection of the air duct 1, the wind force of the air supply mechanism can reach the air outlet hood 5 through the connection shell 2, and under the action of the air outlet hood 5, it is sent to the outside. The acting angle of the air outlet hood 5 can be adjusted by the driving mechanism body 4. The working principle between the driving mechanism body 4 and the air outlet hood 5 is prior art and will not be elaborated here. When the wind force passes through the guiding mechanism 7, under the action of the wind force, the wind direction guiding block 73 can be pushed, so that the wind direction guiding block 73 and the rotating rod 72 rotate under the restriction of the fixed rod 71. Since the outlet position of the wind direction guiding block 73 changes during rotation, the angle at which the wind force exits from the connection air duct 1 will be different, and thus the wind force can act on different positions of the air outlet hood 5, avoiding the situation that most of the wind force of the traditional drum-shaped air outlet exits from the middle position. In addition, under the action of several air distribution blocks 6, the wind force can be preliminarily divided to improve the uniformity of the air outlet of the air outlet hood 5.
