Abstract

The utility model relates to an air convector of improvement structure, including a main shaft, the ring, turbine blade, the piece of helping wind, the upper cover dish, the screw, the ring shaft hole includes a bearing, the outside fan blade that extends of bearing outer loop, and form a water conservancy diversion piece of the anti-direction of rolling over, this turbine blade installs a piece of helping wind on the bevel edge, in order to borrow outside amount of wind auxiliary rotation, and be equipped with vortex water conservancy diversion strip in the upper cover dish, when its vortex water conservancy diversion strip extends nearly upper cover dish outer lane, it becomes an opening form with the upper cover dish turnout, and respectively be equipped with the screw and supply turbine blade two holes to put into the opening with the fix with screw with hole mode around overlapping alternately, in order to prevent that the water bead forms, and then make inside keep dry effect that does not drip.

Description

Structure improved cross-ventilation device

The utility model relates to a kind of ventilation unit, particularly relates to a kind of structure improved cross-ventilation device.

This creation is a kind of structure improved cross-ventilation device.Because the prosperity of population increase and industry and commerce causes the day by day short power shortage of resource, influences the working environment quality.And but traditional cross-ventilation device is owing to need not the electric power whole day rotate and discharge hot-air, and is widely used.But traditional cross-ventilation device by a main shaft, ring, turbo blade, help wind sheet, upper cover plate, screw to form, the disadvantage of its existence is exactly that heat exhaust velocity is low.In order to make product have more benefit, develop high efficiency cross-ventilation device and be necessary in fact.

The purpose of this utility model is to provide a kind of structure improved cross-ventilation device, to increase heat exhaust velocity and significantly to reduce financial cost.

The purpose of this utility model is realized by following technical scheme.

A kind of structure improved cross-ventilation device, comprise a main shaft, ring, turbo blade, help wind sheet, upper cover plate, screw, its improvements are, during this ring moulding one, axis hole comprises a bearing, this outer race several pieces fan blade that stretch out, extend to suitable apart from the time, a flow deflector that forms a reflexed direction connects ring and is integral; By above structure, when body turns round, can borrow fan blade inspiration hot gas, discharge highly humid air by flow deflector from space between ring and the base so that in the body not dewfall, do not drip.Wherein, this turbo blade helps the wind sheet in limit, oblique angle installing one, to borrow outside air quantity auxiliary rotation, and be provided with the vortex flow guide bar at the upper cover plate inner face, when its vortex flow guide bar extends nearly upper cover plate outer ring, open with upper cover plate and to branch off into an opening shape, and respectively be provided with screw and insert opening for turbo blade two holes in juxtaposition front and rear gaps mode and fix with screw, preventing that the water pearl from forming, and then inside is kept dry reach the effect of not dripping.

Concrete structure of the present utility model is provided in detail by following examples and accompanying drawing thereof.

Fig. 1 is an exploded perspective schematic diagram of the present utility model.

Fig. 2 is a combination generalized section of the present utility model.

Fig. 3 is a combination schematic perspective view of the present utility model.

See also Fig. 1, the utility model is by a main shaft, ring, turbo blade, helps wind sheet, upper cover plate, screw to combine.Make a main shaft (10) penetrate ring (20) centre bore, and ring (20) is when one-body molded, having comprised a bearing (21) is to establish for main shaft (10) rotates, this bearing (21) outer shroud (22) outwards launches to extend several pieces fan blade (23) to near-ring circle inner ring (24) position, and the flow deflector (25) that forms a reflexed direction again is connected with inner ring (24).It is fixing with nut (52) at centre bore bearing (51) that this main shaft (10) passes upper cover plate (50).The inner face card of its upper cover plate (50) is provided with vortex flow guide bar (53), when vortex flow guide bar (53) when extending near outer ring, be bifurcated into opening shape (54) with upper cover plate (50), and respectively be provided with screw (55) for turbo blade (30) two holes (31), fixing in juxtaposition front and rear gaps mode with screw (60).Its role is to when outside air temperature is lower than indoor temperature, easy condensate water pearl so the vortex flow guide bar (53) that adds turns round simultaneously with the body blade, just throws away aqueous vapor upper cover plate (50) fast in the cross-ventilation device, guarantee in the cross-ventilation device not dewfall, do not drip.In addition, the set gradient arm of angle of turbo blade (30) (32) installs one additional and helps wind sheet (40), together is fixed in ring (20) outer ring (26), makes it strengthen driving rotation, to improve air output.

See also accompanying drawing 2, the conventional air convector is to utilize stent support ring (20), when body rotates when quick, support just forms " face ", rotary speed reduces the increase of capacity more on the contrary, so the fan blade (23) of utilizing that the utility model is made replaces conventional stent, when rotary speed was accelerated, capacity also increased relatively.Through the reciprocal flow deflector (25) of transferring, its role is to design at hot environment.The body running time highly humid air in the body can be turned by ring (20) with base (70) between space (71) discharge because increased this design, air-breathing in the time of can making running becomes exhaust, avoids combining with the interior air of body because of the highly humid air of rainy institute inspiration.More guarantee in the body not dewfall, do not drip.

See also accompanying drawing 3, the utility model is through continuous research and design improved test, special fan blade (23), flow deflector (25) are inhaled, exhaust structure, particularly design at high humidity environment, the outside highly humid air can't be entered in the body, and upper cover plate (50) top flow guide bar (53) design more can't make the globule splash in the body, and then make inner drying not dewfall, anti-water droplet, significantly promote whole exhaust performance, to increase heat exhaust velocity and significantly to reduce financial cost.

Claims

An air convector with an improved structure, including a main shaft, a ring, a turbine blade, a fan, an upper cover plate, and a screw. It is characterized in that: when the ring is integrally formed, the shaft hole includes a bearing, and the outer ring of the bearing Several fan blades are extended outward, and when extended to an appropriate distance, a deflector in the direction of reflexion is formed to connect the ring into one; the above-mentioned turbine blade is equipped with a wind-assisted blade on the beveled side that can be assisted by external air volume , and there is a vortex guide bar on the inner surface of the upper cover plate, when the vortex guide bar extends close to the outer ring of the upper cover plate, it is bifurcated with the upper cover plate to form an opening shape, and each is provided with a screw hole for two turbine blades The holes are put into the opening in the way of overlapping the front and rear holes and fixed with screws.
