Description

[Detailed description of the invention] This invention relates to a range hood fan that is installed in a cooking room or the like to provide ventilation.

FIG. 1 is a vertical sectional view showing a conventional range hood fan. In the figure, 1 is a wall, 2 is a duct that penetrates this wall, and 3 is a hood body attached to wall 1 so as to be connected to this duct, and is designed to cover the top of an indoor cooking range (not shown). It has a local ventilation port 4 at the lower end and an opening 5 at the front. 6 is a filter provided in the local ventilation opening 4; 7 is a fan provided in the hood body 3;
Collecting exhaust air from local ventilation openings 4 and openings 5,
The exhaust chamber 8 is connected to discharge into the duct 2 . 9 is an upper casing attached to the front upper part of the hood body 3; 10 is a mounting screw for attaching this upper casing to the hood body 3; 1;
Reference numeral 1 denotes a front panel that detachably opens and closes the front of the hood body 3 and the upper casing 9, has a general ventilation opening 12 in the upper part facing the upper casing 9, and fixes the upper or side end with a hook or the like. The other end is fixedly attached to the hood main body 3 with a mounting screw 13. 14 is an anchor bolt for suspending the hood body 3; 15 is a tightening nut thereof; 16
are mounting screws for mounting the hood body 3 to the wall 1.

In the range hood fan configured as described above, the installation work is carried out by first inserting anchor bolts 14 into the ceiling, inserting nuts for fixing the mounting screws 16 into the wall 1, and then attaching the exhaust chamber 8 and the upper casing. 9 and front panel 11
The removed hood main body 3 is suspended from the anchor bolt 14 with the tightening nut 15, and after being fixed to the wall 1 with the mounting screw 16, the exhaust chamber 8 is attached.
is attached to the upper rear surface of the hood main body 3 and connected to the duct 2, and the upper casing 9 is attached to the upper front surface of the hood main body 3 with mounting screws 10, and a front panel 11 is further attached to the entire front surface and closed. Then, when the fan 7 is driven, combustion gas generated from the range due to cooking, as shown by the arrow,
Exhaust smoke, steam, etc. are sucked through the filter 6 from the local ventilation opening 4, and the air from the entire room is sucked through the general ventilation opening 12 and enters the hood body 3, and is further discharged to the outside through the exhaust chamber 8 through the duct 2. be done.

However, when installing such a conventional range hood fan, it is necessary to attach and detach the large front panel 11 and install the tightening nuts 15 and mounting screws 10 upward from the opening 5. The drawback was poor workability.

This idea was made in order to eliminate the drawbacks of the conventional ones as mentioned above.In addition to providing an opening at the top of the hood body, an upper casing is attached to the front upper part of the hood body to cover this opening. To provide a range hood fan with excellent installation workability by forming an opening in the front surface of the fan and providing upper and lower front panels for detachably opening and closing the front surfaces of the upper casing and the hood body, respectively. It is an object.

An embodiment of this invention will be described below with reference to the drawings. FIG. 2 is a vertical sectional view showing a range hood fan according to an embodiment of the invention, and in the figure, 1 to 16 indicate the same or equivalent parts as in FIG. 1. An opening 17 for tightening a tightening nut 15 is provided in the upper part of the hood body 3. The upper casing 9 is attached to cover this opening 17, has an opening 18 corresponding to the opening 17 on the lower surface, and an opening 1 for screwing the mounting screw 10.
9 on the front. Mounting screw 10 is in opening 1
It is mounted downward so that it can be screwed in from 9. The front panel 11 is divided into an upper front panel 11a and a lower front panel 11b. The upper front panel 11a detachably opens and closes the front of the upper casing 9, and the lower front panel 11b detachably opens and closes the front of the hood body 3. One end of the top or side thereof is fixed by a hook or the like, and the other end is fixed with mounting screws 13a and 13b. A general ventilation opening 12 is provided in the upper front panel 11a. The other configurations are similar to those in FIG.

In the range hood fan configured as described above, the hood main body 3 is suspended from the anchor bolts 14 with the exhaust chamber 8, upper casing 9 and upper front panel 11a removed, but at this time, the opening Put your hand in through the opening 17 and tighten the tightening nut 15. Next, install the exhaust chamber 8 and the upper casing 9 to the hood body 3. When installing the upper casing 9, put your hand in through the opening 19 and tighten the mounting screw. Screw 10. After that, the upper front panel 11a is attached and fixed with the mounting screws 13a. Other operations are the same as in the case of FIG.

In the above description, the structure, mounting position, mounting means, etc. of the upper casing 9 can be changed.
Further, the structure, attachment means, etc. of the upper front panel 11a and the lower front panel 11b can also be changed.

As described above, according to this invention, an opening is provided in the upper part of the hood body, an upper casing is attached to cover this opening, and an opening is formed in the front face of the upper casing, and the upper casing and the front face of the hood body are provided with an opening. Since the upper and lower front panels are attached, the tightening nuts and mounting screws can be installed through the openings during installation, and the front panel is divided into two halves, so only one side needs to be installed and removed. This has the effect of significantly improving workability.
