Abstract
The invention relates to a back suction type ventilating fan. The back suction type ventilating fan comprises a fan, a base and a surface shield, wherein the fan is integrally fixed to the base; the surface shield is covered on the base; and the fan and the base are positioned at the back of the surface shield. The back suction type ventilating fan is characterized in that an air inlet or an air inlet grille is arranged on the base; and the air can be sucked into the ventilating fan through the air inlet or the air inlet grille on the base at the back of the surface shield, so as to be exhausted. The air inlet or the air inlet grille is replaced by a flat panel to be arranged on the surface shield, and various patterns are formed on the panel, so that the ventilating fan is like an artwork. According to the back suction type ventilating fan, the coverage area of the surface shield is larger than the area of the base, so that ugly dust and stain on the air inlet or the air inlet grille on the base can be hidden well.
Description
Technical field
The present invention relates to a kind of ventilation fan, specifically, is a kind of back absorption type ventilation fan.
Background technique
Ventilation fan (Ventilatingfan) also claims " ventilating fan ", " ventilation fan ", is a kind of very common small electric apparatus, usually is installed on ceiling board or the metope, is mainly used in upgrading indoor air.Its function mode has two kinds: 1. that indoor Bas Discharged is outdoor, and allow simultaneously outdoor ozone flow into indoor from other passages (such as door and window, ventilated port etc.); 2. outdoor fresh air is sent into indoorly, allowed simultaneously indoor air outside other passage delivery chamber.1. to plant mode more common.
The structure of ventilation fan becomes without large for many years, nothing more than being that a blower fan is fixed on the support, consists of the ventilation fan body, and the outside is joined a face shield again.Blower fan is comprised of motor, impeller or leaf slurry, and the blower fan of some ventilation fan is also with spiral case.The working mechanism of blower fan is very simple, is exactly to drive air-flow by driven by motor impeller or page or leaf slurry, and air is flowed towards predetermined direction, realizes the function of " transportation " air-flow.
Have parts very noticeable in the ventilation fan, that is exactly the face shield of ventilation fan.Suction port or the air-inlet grille of existing ventilation fan all are located on the face shield bar none, or in its front, or in its side.No matter in the front or the side, air-flow all can cover all at one glance through suction port or the left dust spot of air-inlet grille, and is not only dirty but also ugly, and the general frequent wiping of few people is so extinguish cheerfulness and enthusiasm indoor.This is one of the most unluckily shortcoming of existing ventilation fan.
Summary of the invention
The object of the present invention is to provide a kind of back absorption type ventilation fan, the suction port of this ventilation fan or air-inlet grille are from visually being blocked by face shield, and the dust spot that air-flow is stayed is difficult for exposing, thereby has kept attractive in appearance, simultaneously with various pattern decorative covers, for ventilation fan has been given artistic effect.
Technological scheme of the present invention is: a kind of back absorption type ventilation fan, comprise blower fan, support and face shield, described blower fan and pedestal are fixed together, described face shield covers on the support, blower fan and support are positioned at the behind of face shield, it is characterized in that: the suction port of ventilation fan or air-inlet grille are arranged on the support, make air be inhaled into ventilation fan from suction port or air-inlet grille on the face shield support behind, and then discharge.Suction port or air-inlet grille are not set on the described face shield, and the wide coverage of face shield so that the suction port on the support or air-inlet grille being difficult for leak outside, reaches the purpose of hiding the dust spot in the support area.First surface decorating at face shield has various patterns, gives its artistic effect.
The invention has the advantages that: 1. air-inlet grille is designed on the support, from visually being blocked by face shield, dust spot on suction port or the air-inlet grille is difficult for exposing, thereby kept attractive in appearance, 2. suction port or air-inlet grille are not set on the face shield, be convenient to make it to possess the effect of the art work at the various patterns of its first surface decorating.
Description of drawings
Fig. 1 is back absorption type ventilation fan embodiment's exploded sketch.
Fig. 2 is back absorption type ventilation fan embodiment's side-looking general assembly structural representation.
Among the figure: the 1-blower fan; The 2-support; 3-air-inlet grille; The 4-face shield.
Embodiment
In order to be illustrated more clearly in above-mentioned feature and advantage of the present invention, below especially exemplified by embodiment, and cooperate accompanying drawing to do detailed elaboration, but the present invention is not limited to this.
Such as accompanying drawing 1, back absorption type ventilation fan of the present invention comprises blower fan 1, support 2 and face shield 4.Be provided with the air-inlet grille 3 for air amount on the support 2, suction port or air-inlet grille are not set on the face shield 4.As shown in Figure 2, described blower fan 1 is fixed together with support 2, and described face shield 4 covers on the support 2, and blower fan 1 and support 2 are positioned at the behind of face shield 4, and air is inhaled into ventilation fan from the air-inlet grille on face shield 4 support 2 behind, and then discharges.The first surface decorating of face shield 4 has various patterns, makes it to possess the effect of the art work.Because face shield 4 is larger than support 2, so from visually having blocked well the air-inlet grille 3 on the support 2, make the dust spot on the air-inlet grille 3 be difficult for exposing, keeps attractive in appearance.
The above only is preferred embodiment of the present invention, and all equalizations of doing according to the present patent application claim change and modify, and all should belong to covering scope of the present invention.
Claims (3)
1. back absorption type ventilation fan, comprise blower fan, support and face shield, described blower fan and support are fixed together, described face shield covers on the support, blower fan and support are positioned at the behind of face shield, it is characterized in that: the suction port of ventilation fan or air-inlet grille are arranged on the support, make air be inhaled into ventilation fan from suction port or air-inlet grille on the face shield support behind, and then discharge.
2. back absorption type ventilation fan according to claim 1 is characterized in that: suction port or air-inlet grille are not set on the described face shield.
3. back absorption type ventilation fan according to claim 1 is characterized in that: its wide coverage of described face shield is in the support area, so that the suction port on the support or air-inlet grille being difficult for expose.
