Description

Roof cross-ventilation device

The utility model relates to a kind of conditioner.

Along with the development of industry and commerce, market becomes increasingly prosperous, and people's living standard also improves gradually, has also brought resource problem such as shortage and power shortage day by day simultaneously, because the pollution of atmosphere and environment has had a strong impact on the people's work environment.But traditional cross-ventilation device is still regulated for some specific environment needs the indoor temperature of temporary transient closed space or animal feeding field owing to being widely used by electric power all-weather rotation discharge hot-air, and traditional cross-ventilation device is just not really suitable.Therefore in actual life, be sought after a kind of high efficiency, heat exhaust velocity is big, cost is low roof cross-ventilation device.

The utility model relates to a kind of high efficiency, heat exhaust velocity is big, cost is low roof cross-ventilation device.Being specially adapted to some specific environment needs the indoor temperature of temporary transient closed space or animal feeding field to regulate.

The utility model is realized by following manner: this roof cross-ventilation device is to be in the dead eye by spindle set at the ring central shaft hole, and be inserted in a bearing cap, on upper cover plate, be screwed described bearing cap, this main shaft apical axis is positioned at the center of described upper cover plate, be provided with fan blade in the described ring, every fan blade is extended by the inwall of described dead eye to described ring, all be formed with the flow deflector of a reflexed direction at near-ring circle inwall place, be respectively equipped with symmetrical circular arc U-lag on the outer wall of described ring with on the described upper cover plate, assign fixing up and down for curved blade, be arranged with several guiding gutters at described upper cover plate hemisphere dome in addition, described main shaft lower shaft is fixed in the base seat support axis hole.When body rotates, can pass through fan blade inspiration hot gas, and discharge highly humid air from space between ring and the pedestal by flow deflector.The curved blade of this convector adopts suitable circular arc design, can increase its rigidity and not yielding.The effect of the guiding gutter on the upper cover plate is to strengthen the auxiliary rotation of external wind-force.

Described base seat support axis hole is fixed with an iron plate ring, be used for the post hole that projection is inserted and below this base seat support outer shroud, be provided with, and under this base seat support, is furnished with fan lid with projection, what described fan covered is provided with magnet with described iron plate articulating contact, is provided with at the another side of described fan lid to be used to collude the hook ring that draws.The fan lid can be inserted its projection in the protruding hole by the knob action, can load onto and unload for the fan lid like this.Every fan fan lid can be opened by hook ring, can close by magnet suction when closing and close, and controls the amount of opening of every fan fan lid like this, with control room inner air convection amount.

Be arranged with a hole in center, described upper cover plate top, and mid-ly in this hole go into level meter.Vertical-horizontal in order to this convector of control and ground level is laid benchmark.

Be described in further detail below in conjunction with accompanying drawing.

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

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

Fig. 3 is a combination stereogram of the present utility model

As shown in Figure 1: in the centre bore by main shaft 10 cross-under rings 20 bearings that the center is provided with 21, be provided with fan blade 22 in the ring 20, the inwall of this fan blade 22 mind-set ring 20 from ring 20 extends, be formed with the flow deflector 23 of a reflexed direction at near-ring circle 20 inwall places, can make by this flow deflector 23 and air-breathingly to become exhaust and break off the inspiration highly humid air, be respectively arranged with symmetrical circular arc U-lag 24 on the outer wall of ring 20 with on the upper cover plate 40 in addition, 41, assign fixing for curved blade 30, this main shaft 10 also is inserted in a bearing cap 42, centre bore 43 places at upper cover plate 40 cover 42 with screw 44 rigid bearings, these upper cover plate 40 profiles are a hemisphere dome, around its end face, be concaved with several suitable guiding gutter 44, utilize and strengthen air quantity under the external wind-force power-assist, and install a shrinkage pool 45 device one level meter 50 at hemisphere dome centre bit, the lower shaft of main shaft 10 is fixed in the centre bore 62 of pedestal 60 supports 61, and be inserted in an iron plate ring 64 at centre bore 62, and be provided with post hole 63 in addition under support 61 outer shrouds, cover 70 projection 71 for fan and be used as knob and insert.

As shown in Figure 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 utility model is to adopt fan blade 22 to replace conventional stent, when rotary speed is accelerated, capacity also increases relatively, through the reciprocal flow deflector 23 of transferring, its structure is to design at the area that high humidity environment is arranged, the body running time highly humid air in the body can be turned by ring 20 and pedestal 60 between the space discharge because many this designs, air-breathing in the time of can making running becomes exhaust, break off the situation that the highly humid air because of the institute's inspiration of raining combines with the interior air of body, more certain not dewfall that makes in the body is not dripped, moreover the guiding gutter of the hemisphere dome shape of integrally formed upper cover plate 40 efficient that makes it strengthen driving rotation and increase air output, and its dome edge protrudes an eaves limit 46, protects in the rainwater more and oozes.

The physa seat is changeed in the four directions that pedestal 60 also is formed in one, being provided with post hole 63 below pedestal 60 supports 61 outer shrouds cooperates fan to cover 70 projections, 71 formation knob connected modes, can be for opening, closing motion, because pedestal 60 centre bores 62 are installed with an iron plate ring 64, cooperate fan to cover 70 and be equiped with magnet 72 suctions, making fan cover 70 closes, want opening door-leaf to cover at 70 o'clock, cover 70 magnet, 72 opposite sides at fan and be provided with hook ring 73, can draw fan to cover 70 unlatchings for colluding, its fan covers 70 and is divided into four fans, available air output, required and open or close fan according to branch's temperature in the indoor four seasons and cover 70 because of the place, carry out the function adjusting of cross-ventilation device.

As shown in Figure 3, the suitable circular arc design advantage of this curved blade 30 is can shorten the die sinking time and increase output, and biggest advantage is that rigidity strengthens, blade is not yielding.Be installed in this structural most convenient level meter 50 the most accurately, this convector can be reached and the ground level vertical-horizontal exactly; The fan lid 70 of special curved blade 30, guiding gutter 44, fan blade 22, flow deflector 23, adjustment air quantity can improve heat extraction speed really, improves the operating efficiency of this convector, and also reduces financial cost significantly.The utility model is applicable to various indoor environments, can improve room air and temperature.The utility model is specially adapted to some specific environment needs the indoor temperature of temporary transient closed space or animal feeding field to regulate.
