Housing; With
At least two clamping elements that link to each other with housing, each clamping element comprise crooked wooden partition (curved wall), and wherein the convex surface of wooden partition is over against the flange of fan drum, and its surface has the nose parts that the shoulder shape parts with flange are interlocked;
Wherein, employed grille assembly engages by fastening and the fan drum of nose parts with shoulder shape parts, and curved wall is vertical in fact, and She Ji purpose is only to need minimum vertical deflection when making wooden partition be torqued into level orientation like this.
As preferably, fan and grille assembly also comprise the rigidity positioning element that is attached to housing.
As preferably, flange has the guiding groove of inclination, helps in the process of fan drum the curved wall of clamping element to be curved in that grille assembly is installed.
As preferably, take on the shape parts and form groove component.
Instantiation of the present invention will be described further below by reference to the accompanying drawings.The example does not here represent other examples of changing according to the principle of the invention not within the protection domain that the present invention requires.
Description of drawings
Example of the present invention describes in conjunction with the following drawings:
Figure 1 shows that the decomposition diagram of fan of the present invention and grille assembly;
Fig. 2 is installed in partial cross section figure on the ceiling for fan shown in Figure 1 and grille assembly;
Fig. 3 a is the part detail perspective view (for the sake of clarity, having removed ceiling portion) of fan and grille assembly shown in Figure 2;
Fig. 3 b is and the similar view of Fig. 3 a, has shown fan shown in Figure 1 and the flange of grille assembly;
Fig. 4 is the perspective view more specifically (for the sake of clarity, having removed ceiling portion) of the part detail perspective view of fan shown in Figure 2 and grille assembly;
Fig. 5,6 and 7 is vertical view, sectional view and perspective views of the clamping element of grille assembly shown in Figure 4;
Fig. 8 a, the view of 8b and Fig. 2 to 6 have seemingly shown another one variation example of the present invention.
The specific embodiment
With reference to Fig. 1, shown a kind of fan and grille assembly 10.Assembly 10 comprises the shell 20 of the fan that is installed in ceiling with ventricumbent opening 22.Assembly 10 also comprises grille assembly 40, and grille assembly can be carried air, and plays the effect of opening 22 attractive in appearance when seeing from bottom to top.
With reference to Fig. 5,6 and 7, each clamping element 50 has crooked wooden partition 52 and the convex surface 53 of wooden partition.Convex surface 53 is over against the flange of fan drum 20, and its nose parts 54 are also over against the flange 30 of shell 20, as Fig. 3 a and shown in Figure 4.Shoulder shape parts 36 on nose parts 54 and the flange 30 are interlocked, shown in Fig. 3 b.During use, can adopt such assembling mode, grille assembly 40 engages with fan drum 20 by the fastening of nose parts 54 and shoulder shape parts 36.Wooden partition 52 is vertical in fact, and She Ji purpose is only to need minimum vertical deflection when making wooden partition be torqued into level orientation like this.Adopt such design that a lot of benefits are arranged.For example, it can make things convenient for parts 54 to embed groove 37.
With reference to partial cross section figure shown in Figure 2, have an interspace between grille assembly 40 and the ceiling 8 in the installation site.Gap 9 (being generally 2 millimeters) can prevent 40 damages of day perianth grille assembly.In installation process, adjust grille assembly 40 if desired and make it to turn to position more attractive in appearance with respect to smallpox, adopt way at interval that adjustment is had certain help.
With reference to Fig. 3 b, show out the structure of flange 30 in greater detail.The bottom of flange 30 has the guiding groove 39 of inclination, upwards pushes position shown in Figure 2 with the nose parts 54 that help clamping element 50.
With reference to Fig. 3 b, flange 30 has the structure of groove 37, comprises shoulder shape parts 36 and ventricumbent undercut slots surface 38 (undercut surface).Undercut slots surface 38 provides the position that nose parts 54 are embedded, as shown in Figure 2.Thereby having simplified shoulder shape parts 36, the flange 30 in another example (not shown) of the present invention do not need undercut slots surface 38.
Be installed to being described below of ceiling 8 for fan and grille assembly.At first adopt convenient suitable method to cut an opening at ceiling 8.Then, fan component 20 is upward through opening modestly puts into ceiling 8, coincide up to the upper surface 31 of flange 30 and the lower surface of ceiling 8.Tightening liftinglug 26 (retention lugs) screws out from ceiling 8 and makes fan component 20 be fixed on the back side of ceiling, as illustrated in fig. 1 and 2.After fan fixed the position, grille assembly 40 just can have been installed.
After the installation, clamping element 50 can make it more firm for flange 30 provides pressuring action.So just prevented the swing of fan, vibration and noise.
The nose parts 54 of clamping element 50 have a main moving range (several millimeters).Even this moving range can make clamping element 50 also play effect under the situation of ceiling 8 injustice, and can make clamping element 50 be adjusted to different height.Tighten up for the limited active position of method for existing, this is a significant advantage.
Clamping element 50 can make grille assembly 40 be removed from the fixed position at an easy rate.
Another improved example of the present invention is shown in Fig. 8 a and 8b.This example and above-mentioned example are very similar, and difference is that the nose parts 54 of clamping element 50 projections shown in Figure 2 are replaced by shoulder shape parts 36 and the groove 37 shown in Fig. 8 b.And nose parts 54 are installed in above the flange 30 of fan drum 20.
As the present invention during according to above-mentioned case description, various changes all might realize, it should be noted that these are changed not break away from principle of the present invention.Therefore, these changes should be within claimed scope of the present invention.
