Description

The bathroom ventilation fan of improvement

Technical field

The utility model relates to a kind of bathroom ventilation fan of improvement, especially refers to a kind of frame body with removable group, and motor can the preposition bathroom ventilation fan that exposes to frame outlet body the place ahead.

Background of invention

As shown in Figures 1 and 2, known bathroom ventilation fan structure, its motor 2 ' and centrifugal cutter 3 ' all are arranged in the integrally formed bellows 11 ' inner face in frame body 1 ' back, therefore in maintenance, need the bearing frame plate 12 ' of frame body 1 ' inner locking is disassembled, begin to make built-in motor 2 ' to expose maintenance, bearing frame plate 12 ' like this is in the mode of many groups screw locking, and is quite inconvenient for dismantlement work; Again, all be arranged in bellows 11 ' inner face and the same side with said motor 2 ' and centrifugal cutter 3 ', this bellows 11 ' inner face just needs bigger containing space, causes frame body 1 ' overall volume to become big and heavy, the yet heavier inconvenience of dismounting in maintenance relatively is not so its applicability is more attained ideal.

Summary of the invention

Main purpose of the present utility model provides a kind of bathroom ventilation fan of improvement, utilizing its motor and centrifugal cutter to adopt different establishing property of side puts, and motor directly exposes to the frame body, and centrifugal cutter by one can directly tear open fast component from the design of bellows cover cap, in maintenance, only skin plate need be disassembled and directly to see the motor maintenance, or directly bellows are torn open component from, the dust cleaning work of favourable centrifugal cutter, and then, reach maintenance and cleaning work and have convenient simple usability effect.

Another purpose of the present utility model provides a kind of bathroom ventilation fan of improvement, take the not design of homonymy setting in motor and centrifugal cutter, the volume of bellows is reduced relatively, and the volume of whole relatively bathroom ventilation fan also can reduce, weight saving helps the property installed and used of bathroom ventilation fan.

The utility model provides a kind of bathroom ventilation fan of improvement, mainly include frame body, motor, centrifugal cutter and skin plate, this frame body is buckled the binding institute of pulling mutually by fixed plate and bellows and is formed, empty fenestra of this fixed plate bottom basket wherein, and a bolster rib is radially extended at the center of fenestra, and be fixed in motor lock, and make axle wear protruding in outside with the centrifugal cutter winding, motor and centrifugal cutter bearing respectively are positioned not homonymy of fixed plate; And the break-through on the bottom part board face of this fixed plate has two group leader's slotted eyes and several buttons that is the vortex shape positional alignment hole of pulling, this two group leaders slotted eye is worn the termination that buckles into skin plate both sides buckle-assembled element respectively, and the skin plate cover cap is positioned on the frame body and the open end of sealing fixed plate; And these bellows respectively are provided with on the butt joint architrave of open end and the pull protruding bamboo shoot fastener of the corresponding fastening in hole of the button of fixed plate, and the enclosed space of its inner cover cap centrifugal cutter is provided with an air outlet tube in a side, and on the air outlet tube and articulate a blades.

The utility model reaches the convenient simple utilization benefit that maintenance and cleaning work are arranged, and the volume of whole bathroom ventilation fan also can reduce, and weight saving helps the property installed and used of bathroom ventilation fan.

Embodiment

According to taking off technological means and the characteristic members that purpose adopts on the utility model, cooperate diagram to be described as follows in detail now:

See also Fig. 3 to shown in Figure 5, ventilation fan structure in the utility model bathroom mainly includes frame body 1, motor 2, centrifugal cutter 3 and skin plate 4.

This frame body 1 is buckled the binding of pulling mutually by fixed plate 11 and bellows 12 and is become, wherein this fixed plate 11 is a rectangle framework, the empty fenestra 111 of its bottom basket, and a bolster rib 112 is radially extended at the center of fenestra 111, being provided with motor 2 can lock and be positioned, and make axle 21 wear protruding in outside with centrifugal cutter 3 windings, cause motor 2 and centrifugal cutter 3 respectively bearing be positioned not homonymy of fixed plate 11; Again, the break-through on the bottom part board face of this fixed plate 11 has two group leader's slotted eyes 113 and several buttons that is the vortex shape positional alignment hole 114 of pulling, this two group leaders slotted eye 113 can be worn the termination that buckles into skin plate 4 both sides buckle-assembled elements 41 respectively, but causes skin plate 4 cover caps to be positioned on the frame body 1 and the open end of sealing fixed plate 11.

And above-mentioned bellows 12 are a vortex shape framework, it respectively is provided with on the butt joint architrave of open end and the pull protruding bamboo shoot fastener 121 of hole 114 corresponding fastenings of the button of fixed plate 11, but cause bellows 12 strong fixs on fixed plate 11, to link one, but and the inner enclosed space that forms a cover cap centrifugal cutter 3, these bellows 12 1 sides are provided with the air outlet tube 122 that is communicated with the inner space again, and on the air outlet tube 122 and articulate a blades 123, be provided with opening the door as the air draft of air outlet tube 122 is unidirectional, the direction that this blades 123 is opened, the air quantity that only allows bellows 12 inside to be extracted out by centrifugal cutter 3 is discharged, and the gas of air outlet tube 122 outsides can't import.

Therefore, as the bathroom ventilation fan that Fig. 5 disclosed, when 3 starts of motor 2 start centrifugal cutters, the vent 42 of its skin plate 4 can suck the fog in bathroom, fenestra 111 through fixed plate 11 enters bellows 12 inside, must by centrifugal cutter 3 import in the air outlet tubes 122 and discharge in outside, produce the fog effect to alleviate the bathroom.

Learn by above-mentioned, bathroom provided by the utility model ventilation fan structure, its motor 2 is taked not homonymy setting with centrifugal cutter 3, and motor 2 directly exposes to the design of frame body 1, in maintenance, only need skin plate 4 is disassembled, can directly see motor 2 maintenance, and bellows 12 have can directly tear open fast component from design, dust cleaning work in order to centrifugal cutter 3, have suitable use value and progressive, allow the maintenance of bathroom ventilation fan and cleaning work reach convenient simple usability; Again, the design that motor 2 and centrifugal cutter 3 take homonymy not to be provided with, the volume of bellows 12 is reduced relatively, and the volume of whole relatively bathroom ventilation fan also can reduce, and weight saving helps the property installed and used of bathroom ventilation fan.

In sum, the bathroom ventilation fan of improvement that the utility model provides is constructed, and can reach the use value and the purpose of expection really, can utilize on the industry, and be the good model utility of a practicability.
