Description

[Detailed description of the invention] This invention relates to an improvement of a ventilation fan with a filter, and the purpose is to provide a ventilation fan whose filter can be easily cleaned. installation of,
The purpose is to facilitate removal work.

Hereinafter, one embodiment of this invention will be described with reference to FIG. 1. In the figure, 1 is a frame body forming a ventilation passage 2, 3 is a blower installed in this frame via a mounting foot 4, and the electric motor 5 and a blade 6 which is detachably formed on the shaft of the motor. 7
is a panel formed as a part of the frame at one end opening of the ventilation passage 2 formed in the frame 1;
The panel is removably formed, and is provided with a ventilation hole 8 that also serves as a bell mouth in the center, an engaging piece 9 on the upper front of this panel, and an oil pan 19 (described later) on the lower wall. A tongue portion 15 serving as an engaging portion is provided respectively. Reference numeral 11 denotes an opening 1 provided to cover the front side of the ventilation port 8 of the panel 7.
2, the upper wall portion thereof is provided with an engagement hole 13 that engages with the engagement piece 9 and allows the decorative grille 11 to rotate around this engagement portion, and the lower wall portion thereof A recess 14 is formed in the part,
Further, convex portions 16 are provided on the upper and lower side walls. 17 faces the surface of the decorative grille 11 having the opening 12 with a distance therebetween, and has a peripheral edge that is similar to the convex portion 1.
6 and is provided with a large number of openings 12a. 18 is a grease filter provided between the fixing member 17 and the decorative grille 11 so as to be disposed between the decorative grille 11 and the frame body 1, and 19 is a female thread formed at the lower part of the decorative grille 11. Thumb screw (mounting tool) that screws into 10
20 is an oil receiver whose front end is removably attached to the decorative grille 11, and is formed into a dish shape to prevent oil dust falling from the decorative grille 11 and the panel 7 from falling onto the floor, etc.; A projecting piece 21 is provided as an engaging part for detachably engaging with the tongue part 15 to clamp the lower part of the decorative grille 11 to the panel 7.

In the ventilation fan configured as described above, by operating the blower 3, the decorative grille 11
Air is sucked in through the opening 12 of the grease filter 1.
8 to filter oil dust, etc. in the air. This filtered air is discharged outside from the ventilation opening 8 of the panel 7 through the ventilation path 2. In this way, the oil dust filtered by the grease filter 18 or the oil dust attached to the panel 7 flows downward and is collected from the recess 14 into the oil pan 19.
By removing 9, it can be disposed of at any location. Also, by removing this oil pan 19, the decorative grill 1
1 can be removed by rotating the engagement piece 9 on the upper part of the panel 7 as a fulcrum, and the grease filter 18 can also be easily removed by disengaging the fixing member 17 from the protrusion 16. In this way, not only the filter 18 but also the decorative grille 11, the fixing member 17, the panel 7, and the blade 6 can be removed, making cleaning by washing with water or the like easier.

Furthermore, as is clear from the configuration of this example,
A knob screw 20 that is an example of a fitting for the oil pan 19
However, since the ventilation fan can be provided at a large distance W from the surface of the wall where the ventilation fan is installed, it is easy to operate when turning the knob screw 20, and the installation of the oil pan 19 is easy.
It is easy to remove. Incidentally, it is also possible to provide the thumbscrew 20 on the panel 7 side and the protruding piece 21 on the decorative grille 11 side, but in this case, the head of the thumbscrew 20 will be close to the surface of the wall where it is installed, making it difficult to operate. Become.

Note that the filter 18 may be detachably attached to the panel 7 side.

As explained above, this invention includes a frame body forming a ventilation passage, a blower installed in this ventilation passage,
It is removably attached to the front of the frame, has a ventilation hole in the center, and a panel with a hanging tongue formed at the bottom end. is removably engaged with the upper part of the panel and can be opened and closed around the engaging part, and a decorative grille is provided with an oil pan removably attached to the lower end using a fitting, and a ventilation passage is provided in this decorative grille. A filter that is removably installed across the ventilation path, a fixing member that is removably installed on the decorative grille to hold the filter across the ventilation path, and an oil receiver that is removably installed on the lower surface of the decorative grille. The oil pan is provided with a protruding piece that detachably engages with the tongue of the panel, so the decorative grill can be securely attached to the frame when the ventilation fan is in use, and the oil pan can be removed when cleaning. This allows you to remove the decorative grille. Furthermore, since only the oil pan can be removed, the oil accumulated in the oil pan can be appropriately removed.

Furthermore, since the position of the oil pan attachment is moved forward from the frame, the distance between the attachment and the surface of the building wall etc. in which it is installed can be increased, making it easier to remove and install the attachment. This makes it possible to efficiently attach and detach the oil pan.
