Abstract
A door head air inlet tank, comprising a tank body (33), is characterized in that: an acoustic material (34) is stuck on the internal wall of the tank body (33), and a side of the tank body (33) is an air inlet (40), which is connected with a bend channel (41). A movable type uptake (35) is positioned at the other side of the tank body (33). A dismountable filter screen (36) is installed in the movable type uptake (35), and an ornamental hinge air port (37) is disposed outside the movable type uptake (35). A negative iron generator is arranged in the tank body. When the blower fan of an acoustic insulation ventilation window is operated, the outdoor air flows across the bend channel through the air inlet at the inclined upper part of the outdoor of the door leaf and enters into the tank body under the negative pressure action, and then, flows into the room through the hinge air port after being filtered by the filter screen. By using the utility model, the fresh air can enter the room, so that the indoor air flow can be balanced.
Description
Affiliated technical field
The utility model relates to the ventilation unit that a kind of building is used, especially a kind of inlet box that places a head.
Background technology
In order to tackle the interference that city noise causes to people's life, people have adopted a kind of soundproof ventilating window that has blower fan, the soundproof ventilating window that has blower fan is in the process of using, the air of the big flow of cause is discharged to outdoor by the wind wheel of blower fan, caused indoor generation negative pressure, air mass flow is unbalance, and is stuffy.
Summary of the invention
The purpose of this utility model provides an a kind of door inlet box, cooperates the soundproof ventilating window that has blower fan to use, and causes indoor airflow balance, replenishes fresh air.
The purpose of this utility model is achieved in that an a kind of door inlet box, comprise air inlet box body, described cabinet wall posts sound-absorbing material, one side of casing is an air inlet, air inlet is connected with an elbow passage, the opposite side of casing has a movable air outlet, a removable filter net is housed in the movable air outlet, be equipped with outward and have ornamental louver air port, casing is installed between a doorframe top and the wall, one side of casing air inlet is contained in outdoor, and a side of movable air outlet is contained in indoor.
When the blower fan of the soundproof ventilating window that has blower fan started, because of suction function, outdoor fresh air entered casing through the air inlet of the door inlet box elbow passage of flowing through, more after filtration behind the net filtration by in the inlet chamber of louver air port.
Negative oxygen ion generator is set in the casing.
After adopting the utility model, in the fresh air inlet chamber, cause indoor air flows to reach balance, the utility model has detachable screen pack, stops in the dust dirt inlet chamber.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 door of the present utility model inlet box structural representation.
33. casings among the figure, 34. sound-absorbing materials, 35. movable air outlets, 36. screen packs, 37. louver air ports, 38. doorframes, 39. door leafs, 40. air inlets, 41. elbow passages.
The specific embodiment
As shown in Figure 1, an a kind of door inlet box, comprise casing 33, described casing 33 is to be made by aluminium alloy or other metal or timber, casing 33 inwalls post sound-absorbing material 34, one side of described casing 33 is an air inlet 40, air inlet is connected with an elbow passage 41, an other side of casing 33 has a movable air outlet 35, a removable filter net 36 is housed in the movable air outlet 35, ornamental louver air port 37 is housed outward, casing 33 is installed between doorframe 38 tops and the wall, one side of casing air inlet 40 is contained in outdoor, and a side of movable air outlet 35 is contained in indoor.When the blower fan of the soundproof ventilating window that has blower fan starts, because of suction function, outdoor air enters casing 33 through the outdoor oblique upper air inlet 40 of the door leaf 39 elbow passage 41 of flowing through, filter the back by having in the inlet chamber of ornamental louver air port through filter screen 36 again, screen pack can take out cleaning.
In order to improve the quality of air, can also in air inlet box body 33, negative oxygen ion generator be set, make room air more pure and fresh.
