Abstract
The utility model provides a watertight structure of ventilator, which comprises a frame, a air inlet cover and a switching curtain, wherein the first rib is arranged at the contact place of the frame and the air inlet cover in the inner side of the frame, the utility model can effectively avoid water entering inside of ventilator and improve the safety.
Description
Technical field
The utility model relates to a kind of ventilation fan, refers in particular to a kind of waterproof construction of ventilation fan.
Background technique
Ventilation fan is the electrical equipment that people are familiar with, and is used to change indoor air.As shown in Figure 1, generally, the air-inlet cover 110 of ventilation fan 100 is positioned at indoor, is connected in an end 121 of framework 120.The part of framework 120 is positioned at window, the other end 122 of framework stretches out window and is positioned at outdoor, for preventing that foreign matter from entering in the framework 120, therefore be provided with movable switch curtain 130 in the outer end of framework 120, this switch curtain 130 is connected by one 131 top with framework 120, and switch curtain 130 can upwards be dug several angle around this axle 131.Generally, rainwater can be blocked by the switch curtain, can not enter easily in the framework, but when rainwater was big, rainwater still might enter the switch curtain, flows on the framework, and infilters the room from the slit between framework, perhaps touches the band live part of ventilation fan.Therefore there is necessity of further improving Security.
The model utility content
The purpose of this utility model is to provide a kind of waterproof construction of ventilation fan, can prevent better that rainwater from entering ventilation fan inside.
For achieving the above object, the waterproof construction of a kind of ventilation fan that the utility model provides comprises framework, air-inlet cover, switch curtain, is characterised in that the inboard at framework, establishes the first road muscle at framework and the contacted place of air-inlet cover.Framework and contacted local the setting and the integrated muscle of framework of air-inlet cover, Sometimes When It Rains, even rainwater enters framework, but the barrier effect of muscle can prevent that still rainwater from flowing into ventilation fan inside and touching electric component along framework.Reached the effect that anti-sealing enters ventilation fan inside.
The waterproof construction of described ventilation fan is characterized in that, the described first road muscle is towards the air-inlet cover bending and encases air-inlet cover.The first road muscle that is located at the framework inboard encases the design of air-inlet cover, and order flows in the more difficult inflow ventilation fan of rainwater of framework.Further improved the sealing of ventilation fan, anti-sealing enters the inside of ventilation fan.
The waterproof construction of described ventilation fan is characterized in that, also forms the structure to the bending of switch curtain on the described first road muscle.When the part of indoor bending encases air-inlet cover, increase the structure to outdoor bending at the first road muscle, it is inner and indoor to make rainwater be difficult to enter ventilation fan, further improves the water proofing property of ventilation fan.
The waterproof construction of described ventilation fan is characterized in that, is provided with sealing material between described first road muscle and the described air-inlet cover.The design of sealing material, make the first road muscle and air-inlet cover the contact face between the space seal more, improve the sealing of ventilation fan biglyyer, anti-sealing enters the inside of ventilation fan.
The waterproof construction of described ventilation fan is characterized in that, establishes the waterproof cover of an activity again in the place that the top of switch curtain contacts with framework.The design of waterproof cover makes rainwater not flow into the ventilation fan from the space of switch curtain and framework tie point.Improve the sealing of ventilation fan, anti-sealing enters the inside of ventilation fan biglyyer.
The waterproof construction of described ventilation fan is characterized in that, establishes the second road muscle on the limit of switch curtain inboard.Establish the second road muscle by pasting framework on switch curtain inner side edge, the sealing of strengthened frame and switch curtain prevents that rainwater from entering.
The waterproof construction of described ventilation fan is characterized in that, establishes sealing material between described second road muscle and the switch curtain edge.The setting of sealing material has been filled up the space of switch curtain and framework, thereby has been improved sealing, prevents that better rainwater from entering the inside of ventilation fan.
The waterproof construction of described ventilation fan is characterized in that, framework is tilted to the switch curtain gradually by air-inlet cover.This by indoor to the outdoor structure that tilts gradually, for example, the thickness of framework by indoor to outdoor attenuation gradually, make and rest on the water of framework naturally to outdoor outflow.Improved drainage performance, prevented that rainwater from entering the inside of ventilation fan.
In sum, the utlity model has good get water-proof performance, the Security that has improved ventilation fan.

Embodiment
Shown in Fig. 2 A, Fig. 2 B, this figure is the utility model first embodiment's schematic representation.Ventilation fan 100 includes framework 120, air-inlet cover 110, switch curtain 130.The first road muscle 140 is located at the inboard of framework 120, and the position is in framework 120 and air-inlet cover 110 contacted places.For improving sealing, between the first road muscle 140 and described air-inlet cover 110, also be provided with the sealing material 141 of annular.The second road muscle 150 is pasting framework and is being located on the switch curtain inner side edge.For improving sealing, between the second road muscle 150 and switch curtain 130 edges, also establish sealing material 151.Framework 120 is tilted to switch curtain 130 gradually by air-inlet cover 110, has improved drainage performance, even there is rainwater to enter framework 120, also owing to gravity, can not continue to the ventilation fan internal penetration.
As shown in Figure 3, be the utility model second embodiment's schematic representation.The first road muscle 140 is towards air-inlet cover 110 bendings and encase air-inlet cover 110, helps preventing the intrusion of rainwater like this.
As shown in Figure 4, be the utility model the 3rd embodiment's schematic representation.The part 142 of the first road muscle 140 is towards air-inlet cover 110 bendings and encase air-inlet cover 110, and the structure that another part 143 forms to the bending of switch curtain (not shown) so more helps preventing the intrusion of rainwater.
As shown in Figure 5, be the utility model the 4th embodiment's schematic representation.On first three embodiment's basis, can establish movable waterproof cover 160 on the top and the place that framework 120 contact of switch curtain 130, block rainwater and enter switch curtain inside from spools 131 of switch curtain.
Only be to be that example is illustrated with the rainwater in the literary composition, the utility model can prevent effectively that class foreign matters such as snow-broth, hail, sewage from entering ventilation fan, to keep clean in the ventilation fan, provides Security.
