Abstract
In the utility model, a wedge-shaped air deflector (4) is arranged at (an air inlet (6)) of a booster fan in an air supply elbow (1) used for a suite fresh air ventilation system for the first time. The wedge-shaped air defector is replaced for a moving one-way baffle arranged at the air inlet or the air outlet of a booster air channel of the prior air supply elbow. Under the two states of stopping and running of the booster fan and owing to the action of the wedge-shaped air deflector (4) in the air supply elbow (1), the air flow resistance passing through the air supply elbow (1) is reduced to a greater degree, the production technology of the air supply elbow (1) is simplified, and the work efficiency of the fresh air ventilation system is improved.
Description
Technical field:
The utility model relates to and a kind ofly at the booster fan intake grill air-supply elbow of spliting type wind deflector is set, a kind of specifically be used for the suite ventilation air interchange system at the booster fan intake grill air-supply elbow of spliting type wind deflector is set.
Technical background:
Existingly be used for the suite ventilation air interchange system because the ventilation in room in the suite often is among the variation, the ventilation of ventilation air interchange system also needs to change thereupon.The existing ventilation air interchange system elbow of often will blowing is designed to two air channels, and booster fan need be installed in supercharging air channel wherein, so as when ventilation air interchange system to increase the ventilation of raising ventilation air interchange system.Booster fan remains static when the ventilation of ventilation air interchange system is little, in order to reduce the resistance of air-flow, often at the intake grill or the exhaust outlet in supercharging air channel movable unidirectional baffle plate has been installed.So just bring two problems, booster fan remains static, and the movable unidirectional baffle plate of the intake grill in supercharging air channel or exhaust outlet tends to be blown afloat by the air-flow in normal air channel, and static booster fan has just become the resistance of air-flow; The unidirectional baffle plate of activity need be blown afloat during the booster fan running,, increase the energy consumption of booster fan because there is deadweight in movable unidirectional baffle plate.
The model utility content:
The purpose of this utility model is air-supply elbow mounting process complexity, the higher problem of energy consumption that is used for the suite ventilation air interchange system at existing, designs a kind of simple and lower air-supply elbow of energy consumption of installation that is applicable to the suite ventilation air interchange system.
The technological scheme of model utility is:
A kind ofly the air-supply elbow of spliting type wind deflector is set, it is characterized in that at the booster fan intake grill; The intake grill (6) of the booster fan in air-supply elbow (1) is provided with spliting type wind deflector (4).
It can be plane that the intake grill (6) of described booster fan in air-supply elbow (1) is provided with spliting type wind deflector (4)
The intake grill (6) of described booster fan in air-supply elbow (1) is provided with spliting type wind deflector (4) also can cabochon.
Described can be single air channel in air-supply elbow (1).
Described also can be two air channels in air-supply elbow (1).
Because the utility model intake grill of the booster fan in being used for the air-supply elbow of suite ventilation air interchange system first is provided with the spliting type wind deflector.Substituted existing air-supply elbow in the supercharging air channel the movable unidirectional baffle plate in the installation of intake grill or exhaust outlet.In the production of air-supply elbow, reduce cost, simplified mounting process, reduced the energy consumption of ventilation air interchange system.

Embodiment:
Below in conjunction with drawings and Examples the utility model is described further.
Embodiment one.
As Fig. 1, shown in Figure 3.
Air-supply elbow (1) among Fig. 1 be single air channel.Spliting type wind deflector (4) is a plane.Mainly be applicable to the less suite in air sucking mouth (10) of ventilation air interchange system.When the part room in the suite is in stuffy or ventilation when little, booster fan (4) is stopped, ventilation air interchange system the running of main ventilating fan (9) under, air-flow in the ventilation duct (12), because the effect of the spliting type wind deflector (4) in the air-supply elbow (1), the air-flow that advances along the wind-guiding circuit is able to smoothly by air-supply elbow (1); Many places, room in suite are in ventilation state,, ventilation air interchange system bigger than normal, booster fan (4) entry into service.At this moment, the booster fan intake grill (6) between booster fan (4) and the spliting type wind deflector (4) has stayed enough spaces, can satisfy the needs of booster fan (4) exhausting.Like this, along with the adjusting of the interior air quantity of ventilation duct (12) of ventilation air interchange system, adapted to the ventilation requirement of different periods of suite.
Embodiment two.
As Fig. 2, shown in Figure 4.
Air-supply elbow (1) among Fig. 1 be two air channels.Spliting type wind deflector (4) is a cabochon.Mainly be applicable to the more suite in air sucking mouth (10) of ventilation air interchange system.At this moment the elbow (1) of often will blowing is set to two air channels.When the part room in the suite is in stuffy or ventilation when little, booster fan (4) is stopped, ventilation air interchange system the running of main ventilating fan (9), the most normal air channel (2) of air-flow in the ventilation duct (12) by air-supply elbow (1), a small amount of air-flow by supercharging air channel (7), under the effect of spliting type wind deflector (4), also can keep less resistance.Many places, room in suite are in ventilation state, because the effect of spliting type wind deflector (4), the air loss that supercharging air channel (7) produces can reduce significantly, at this moment two strands of air-flows by air-supply elbow (1) form the interflow in the ventilation duct airduct road (12) of ventilation air interchange system, and and the blast that produces of the main ventilating fan (9) of ventilation air interchange system running form the wind relay, can not only satisfy the ventilation requirement in room of main ventilating fan (9) near-end of ventilation air interchange system, also can satisfy the ventilation requirement in room of main ventilating fan (9) far-end of ventilation air interchange system.
