Abstract

The utility model is a long-range variable flow state air blast vent which is used to the air supply of the air-conditioner end. The device comprises a housing, an active and a passive guide vans, a middle supporting body, a traction piece of elastic material which connects the active and passive guide vans; an electric actuator takes a driving shaft with active guide van to do the rotation of 0 degree to 180 degrees in anticlockwise or clockwise direction, and the guide piece of elastic material takes n passive guide van to rotate around the fixed axle in the same angle, the air-supply port can change the wind speed and the air-outlet direction optionally to satisfy the requirements of different airflow indoors in winter and summer season.

Description

The long drive journey becomes the fluidised form air outlet

Technical field:

The utility model belongs to the air-conditioning air outlet, is mainly used in the air-supply of air conditioning terminal, can realize the refrigeration or the heating of large space, and cold wind or warm braw are delivered to than distant positions.

Background technology:

Large space has proposed new requirement to the position of central air-conditioning in the modern architecture, and the building higher as floor height, that span is bigger requires layering that the mode of movement that send under the warm braw of air-conditioning is set.The central air-conditioning end that when central air-conditioning is installed, all should possess corresponding function, just can demonstrate fully its effect, especially for large space, adopt traditional air conditioning and heating, because floor height is higher, thermal stratification is serious, does not reach desirable heating effect, also waste energy greatly, general air port exist again winter hot blast send to get off and summer the cold wind too fast drawback that descends.And the pipeline water conservancy diversion of traditional approach employing metallic conduit, aspect installation, occupy very large space, thereby reduced the utilization rate of the indoor useful space.

Summary of the invention:

The purpose of this utility model is that the problem at above background technology provides a kind of and do not establish ventilation shaft and can eliminate thermal stratification, realizes balanced ventilation, and can adjust the air outlet of air-flow fluidised form.

Structure of the present utility model such as Fig. 1 ~ shown in Figure 2, comprise that by pipe section (11) and the inner surface identical with pipe section (11) internal diameter be the air outlet housing that the interception section (2) of sphere welds together formation, there is the flange (5) that links with air-conditioning unit or airduct its upper edge, there is the ring flange (1) that links with frame the section of intercepting ball lower edge, in the air outlet housing, have and be bearing on the intermediate support (7) and the guide vane (6 on the periphery air outlet housing, 8), one initiatively guide vane (6) and driving shaft (4) are fixedly connected, driving shaft (4) the inner can be bearing in the axis hole of opening on intermediate tubular supporting mass (7) tube wall, outer termination YE (3), turn round with YE (3), n passive guide vane (8) can rotate around fixed axis (9), the inner of fixed axis (9) is fixedly connected on intermediate support body (7), the outer end is fixedly connected on blower case (2,11); Traction piece (10) with the elastomeric material formation, initiatively guide vane (6) and passive guide vane (8) elasticity link together, YE (3) drive driving shaft (4) is done between 0 °～180 ° counterclockwise or is turned clockwise, and drives passive guide vane (8) is made equal angular around fixed axis (9) rotation by elastic traction part (10).Elastic traction part (10) is connected with guide vane by the hole (h) on each guide vane.

Characteristics of the present utility model are that nationality helps newly-designed air outlet, can arbitrarily change wind speed and air-out direction, to satisfy winter and the requirement of summer to indoor different air-flows, the hot blast that is used for large space down can be delivered to hot blast ground during air-supply, the warm phenomenon of layer that the thermal current that has changed general heating system existence rises and causes, can adjust the flow velocity and the diffusion angle of cold airflow summer again, the formation temperature uniform airflow, eliminate the sense of discomfort that spout below personnel cause because of excessive temperature differentials, owing to adopt remote air-supply, can cancel pipeline, exempting airduct makes and installation workload, reduce space crossed operation, and the reduction of erection time, reduced the cost of large space air conditioning terminal system.

Best implementation:

The long drive journey becomes the fluidised form air outlet, constitutes with the spherical shell section (2) by pipe section (11) and georama; As adopting welding method with ferrous materials, as with the also available bonding forming of other materials, available helical spring of elastomeric material traction body (10) or wire spring, each guide vane has a hole (h) to be connected with elastic traction part (10), when one initiatively guide vane rotates, the a series of elastic traction body (10) that affects on several passive guide vanes (8) can make itself and active guide vane do the rotation of equal angular.

Claims

1, a kind of long drive journey becomes the fluidised form air outlet, it is characterized in that: by pipe section (11) and the inner surface identical with pipe section (11) internal diameter is the air outlet housing that the interception section (2) of sphere welds together formation, there is the ring flange (5) that links with air conditioner or airduct pipe section upper edge, the section of intercepting ball F is along the ring flange (1) that links with frame is arranged, in the air outlet housing, have and be supported on the intermediate support (7) and the guide vane (6 on the air outlet housing, 8), one of them active guide vane (6) and its driving shaft (4) are fixedly connected, rotate in the axis hole that driving shaft (4) the inner can be left on intermediate tubular supporter (7) tube wall, the outer end connects YE (3), turn round with YE (3), several passive guide vanes (8) can rotate around its fixed axis (9), the inner of fixed axis (9) is fixedly connected on intermediate support (7), the outer end is fixedly connected at air-supply casing (2,11) on, elastic traction part (10) with the elastomeric material formation, initiatively guide vane (6) and several passive guide vane (8) resilient connection be together with one, YE (3) drives driving shaft (4) and does 0 °～180 ° counterclockwise or turn clockwise, and drives by elastic traction part (10) and severally to be centered on the rotations that fixed axis (9) is made equal angular by moving vane (8).
