Abstract
The utility model discloses an indoor air centralized-emission apparatus, which is characterized in that a plurality of streamline plates (2) are fixedly connected with the inner wall of a pipeline (1); the streamline plates (2) are longitudinal arch strip plates; an air inlet (4) is arranged at the central section of a pipe wall; an air outlet (5) is arranged at the middle-upper part of the streamline plates (2); a plurality of isolation plates (3) are arranged between the streamline plates (2). The utility model has the advantages of fast exclusion of the wind, no discharge of the air, and applicability for multi-rooms exhausting.
Description
Affiliated technical field
The utility model belongs to a kind of building material made, is meant that especially a kind of room air concentrates tapping equipment.
Background technology
Along with improving constantly and residential housing fast development already of people's living standard, resident's living space is increasing, and multiple functional, and bedroom, parlor, kitchen and toilet are available in all varieties.Yet because very tight door and window is mostly adopted in present room, ventilation effect is poor.Especially at winter and summer, should not window, the flue gas in the parlor and the foul atmosphere in room are difficult to discharge, and cause IAQ poor.Especially decorate the room that causes pernicious gas to exceed standard, the lighter impairs one's health, weight person's threat to life safety.Thereby, need to be provided with the air tapping equipment in the room.Existing fume emission road is made up of the dividing plate of pipeline and inner chamber thereof, and dividing plate is the vertical bar plate parallel with pipeline, and it is divided into major and minor air channel with inner cavity of pipe, and secondary air channel upper end open communicates with main air duct, and duct wall has air inlet.It has the following disadvantages: the indoor flue gas that enters from air inlet moves in secondary air channel, enter concentrated discharge the in the main air duct from upper end open, but its anti-weak effect against the wind, flue gas in the main air duct enters secondary air channel easily, then in the inlet chamber, cause gas blowby, not only influenced air draft, even run counter to desire.Therefore this indoor fume emission device science not is also impracticable.
Summary of the invention
The purpose of the utility model is to provide a kind of novel room air to concentrate tapping equipment, and it has overcome the above-mentioned deficiency of prior art, and it is fast to have an air draft, and suction is big, not advantage such as gas blowby; And the air in suitable many rooms discharging.
For reaching above-mentioned purpose, the utility model is taked following technical scheme: the utility model is at inner-walls of duct some fairing plates that have been fixedly connected, fairing plate is longitudinal arched batten, tube wall middle part with respect to fairing plate has air inlet, the middle and upper part of fairing plate has air outlet, and division board is arranged between fairing plate.
The utility model is taked technique scheme, has following beneficial effect: the utility model is because at the inner-walls of duct fairing plate that has been fixedly connected, and the air that enters from air inlet enters main air duct by the air outlet of fairing plate middle and upper part.Move on the air of main air duct, when flowing through the arch fairing plate, air quickens to move at the minimum place of middle part internal diameter, cause the place, fairing plate middle and upper part of arch to produce the high negative value, make the air outlet of fairing plate produce the suction that points to main air duct, thereby the respective chambers air enter fast under the effect of suction main air duct and on move, reach the purpose of quick exhaust.Like this, thoroughly prevented to pour in down a chimney against the wind phenomenon.In addition, between a plurality of fairing plates, set up division board, the air between the fairing plate can not scurried mutually, also increased rigidity of the present utility model simultaneously.
Description of drawings
Below in conjunction with drawings and Examples the utility model is described.
Fig. 1 cuts open figure for the utility model master TV structure.
Fig. 2 cuts open figure for Figure 1A-A.
The specific embodiment
As seen from Figure 1: the utility model includes pipeline 1, fairing plate 2, division board 3, and fairing plate 2 is longitudinal arched batten, and two ends are fixed on pipeline 1 inwall up and down.Pipeline 1 middle part with respect to fairing plate has air inlet 4, and fairing plate 2 middle and upper parts have air outlet 5.As seen from Figure 2: fairing plate 2 and division board 3 can be many, to adapt to the air discharging in different angles, different rooms.
