Description

A kind of water proof type exhaust hood

Technical field

The utility model relates to air purification field more particularly to a kind of water proof type exhaust hoods.

Background technique

As the improvement of people's living standards, to public arena, especially the requirement of indoor spaces air environment is increasingly Height, for example, the places such as office, Recreational places, family room.Either spring, summer, autumn and winter, we be desirable in interior have it is easypro Suitable air environment.And this rainy season in summer, similarly it be unable to do without indoor air exchange.But it is net in air The air draft link of change system, it is more contradictory for encountering the rainy day.Because, on the one hand, to meet the needs of ventilation, air ejector fan is just Need to carry out always air draft work, on the other hand, rainwater can enter blower from exhaust outlet, cause blower short-circuit, damage.

Currently, water proof type exhaust hood is generally included in exhaust outlet or setting hardware grid or setting by the way of Waterproof protecting cover, waterproof rib, these are all fixed structures, and regardless of weather condition, unalterable structure is caused sometimes Air draft windage is higher, and energy consumption is big, also, when not in use, can not prevent the immersion of dust, sundries, increase The expense of exhaust equipment maintenance, repair.

Summary of the invention

The utility model against the above deficiency, provides a kind of waterproof, anti-gray, energy-efficient exhaust hood.

In order to solve the above problem, the technical solution adopted in the utility model are as follows:

A kind of water proof type exhaust hood, including cover, shutter, blower, the blower are bolted inside cover, The shutter is bolted to one end of cover；

The shutter includes window frame, blade and the shaft for opening and closing shutter, and the blade has diversion trench, the window frame Equipped with protruding into part；

The bottom of the cover and shutter connecting pin is equipped with discharge outlet, and the cover and the port of shutter connecting pin are set Fluted, the part that protrudes into is inserted into the groove.

Further, humidity sensor is equipped with outside the window frame, the humidity sensor is electrically connected central processing unit, The output end of the central processing unit is electrically connected hoist, and the hoist connects the shaft.

Further, the inside of the cover, be hinged between the blower and the shutter top flap and Bottom baffle.

Further, colloid is marked in the groove.

Further, the part side wall that protrudes into has a protrusion, the shape of the protrusion be circle, triangle, rectangle wherein One kind.

Compared with prior art, the utility model has the beneficial effects that

The utility model controls the folding of exhaust outlet using shutter, and issues diversion trench on the blade of shutter, benefit Achieve the effect that draining with the self weight of rainwater, and can choose the opening and closing degree of exhaust outlet according to practical weather condition, improves The scavenging efficiency of air cleaning system, energy saving；Further, using automatic control equipment, manual control is reduced, day is avoided Gas mutation leads to the problem of controlling not in time.

Cover and recovering the oil in junction for forms have reeded structure, on the one hand, increase the combination of cover and forms Tightness, on the other hand, sealing effect is good, prevents the immersion of rainwater.Furthermore, it is possible to select the hinged detachable top inside cover Portion's baffle and bottom baffle, tilt angle is adjustable, for rainy weather, enhances water-proof function.

Detailed description of the invention

Fig. 1 is the structural schematic diagram of the utility model；

Fig. 2 is the structural schematic diagram that the utility model increases baffle.

Specific embodiment

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work Every other embodiment obtained, fall within the protection scope of the utility model.

As shown in Figure 1, the utility model provides a kind of technical solution:

A kind of water proof type exhaust hood, including cover 1, shutter 3, blower 2, blower 2 are bolted in cover 1 Portion, shutter 3 are bolted to one end of cover 1；

Shutter 3 includes window frame, blade 34 and the shaft 35 for opening and closing shutter, and blade has diversion trench 33, and window frame is equipped with Protrude into part 32.The folding of exhaust outlet is controlled using shutter 3, and issues diversion trench 33 on the blade of shutter 3 34, utilizes rain The self weight of water achievees the effect that draining, and can choose the opening and closing degree of exhaust outlet according to practical weather condition, for example, raining More weather, shutter 3 are in half-open position；Bright day gas, shutter 3 are in the state of standard-sized sheet；Without using when, In full off state, moreover it is possible to which the entrance for preventing dust improves the scavenging efficiency of air cleaning system, energy saving.

The bottom of cover 1 and 3 connecting pin of shutter is equipped with discharge outlet 12, and cover 1 and the port of shutter connecting pin are equipped with Groove 11 protrudes into part 32 and is inserted into groove 11.

Humidity sensor is equipped with outside window frame, humidity sensor is electrically connected central processing unit, and processor model is SIMATIC S7-300, output end are electrically connected hoist, and hoist connects shaft, and electric connection line is RS485 bus.More Further, using automatic control equipment, manual control is reduced, avoids the problem that change in weather leads to control not in time.

As shown in Fig. 2, the inside of cover 1, is hinged with top flap 14 and bottom gear between blower 2 and shutter 3 Plate 13.It can choose hinged detachable top flap 14 and bottom baffle 13 inside cover, tilt angle is adjustable, right In rainy weather, enhance water-proof function.

It is marked with colloid in groove 11, protruding into 32 side wall of part has protrusion 31, and the shape of protrusion 31 is circle, triangle, square Shape is one such, is round in the present embodiment.Cover 1 and forms 3 use the structure with groove 11 in junction.One side Face increases the bonding tightness of cover 1 and forms 3；On the other hand, sealing effect is good, prevents the immersion of rainwater.
