Description

[Detailed description of the invention] This invention relates to a ventilation fan with a decorative grille on the front, and the direction of the decorative grille is changed by 90 degrees in order to position the decorative grille formed by a lattice vertically or horizontally. To enable a mark provided on a decorative grill to be easily converted to the correct direction even in the case of a decorative grille.

As shown in FIG. 1, in a conventional ventilation fan, a mark 102 is fixed to a decorative grille 101 formed by a lattice or the like, so when it is desired to change a horizontal lattice-shaped decorative grille 101 to a vertical lattice-shaped decorative grille 101, the decorative grille 101 When the direction of the mark 10 is changed and installed, the mark 10 provided on the decorative grille 101
2 was in a state where it was displaced by 90 degrees and could not be made into the correct mark state.

Therefore, a ventilation fan with a horizontal lattice decorative grille and a ventilation fan with a vertical lattice decorative grille were made separately, and the ventilation fan with a decorative grille suitable for the interior of the installation location was installed. I had to make two types of ventilation fans just because the grids were different.

Furthermore, if you want to change the horizontal lattice to a vertical lattice due to changes in the interior after installing the ventilation fan, you have to groove the ventilation fan and replace it.

The present invention solves the above-mentioned conventional drawbacks, and embodiments thereof will be described below with reference to FIGS. 2 to 6.

In the figure, 1 is a ventilation fan body with a fan motor 2 installed inside, and 3 is a square decorative grill that is removably attached to the front side of the ventilation fan body 1, and can be attached and detached even if the decorative grill 3 is displaced by 90 degrees. It is set in.

4 is a mark attached to the decorative grille 3, and a support shaft 5 is provided at the center of the back.

6 is a groove provided in the support shaft 5 so that the E-ring 7 engages;
8 is a pin provided above the support shaft 5 on a vertical line of the support shaft 5 provided on the mark 4; 9 is a pin provided at the center of the mark mounting seat 10 of the decorative grille 3 for fitting the support shaft 5; The hole 11 is located on the vertical line and the horizontal line of the insertion hole 9, and is provided so that the pin 8 provided on the mark 4 engages when the support shaft 5 is rotatably supported in the insertion hole 9. engagement hole,
Reference numeral 12 denotes a spring that is inserted into the outer periphery of the support shaft 5 into which the insertion hole 9 is inserted, and is located between the E-ring 7 provided on the support shaft 5 and the back of the decorative grille 3, and the mark 4 is always attached to the decorative grille. It is provided so that it is attracted to the surface side of 3.

Note that the mark 4 is configured so that when the pin 8 provided on the mark 4 is located above the support shaft 5, the mark is in the correct state.

In the above configuration, the decorative grille 3 is as shown in FIG.
When the mark 4 is set in the correct position in the horizontal lattice state, if you want to use the decorative grille 3 in the vertical lattice state as shown in FIG. A mark 4 is placed on the engagement hole 11 located above the support shaft 5 when it is pulled and made into a vertical grid.
The mark 4, which was set in the correct state in the horizontal lattice state, is now set in the correct state in the vertical lattice state. It is something.

As described above, according to the present invention, even if the direction of the decorative grille is changed depending on the installation or interior of the place where the ventilation fan is installed, the mark provided on the decorative grille can be set in the correct state with a simple operation. This eliminates the unsightly appearance of the mark being used horizontally, and also eliminates the need to create separate decorative grilles for vertical and horizontal orientations.
