[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a range hood fan that removes water and oils and fats contained in flue gas containing waste gas rising from burning appliances and cooked foods, and cleans and exhausts it. The present invention relates to a range hood fan with improved operability and exhaust efficiency of a provided operating section.

[0002]

2. Description of the Related Art A range hood fan is supported by a front plate, a hood body having an exhaust device, a partition plate provided on the hood body, a tip of the partition plate, and a filter bar provided on the top plate portion of the hood body. There is a filter provided with the filter, and its front plate is inclined toward the front room floor direction in order to expand the smoke trapping space. The range hood fan is provided with an operation unit for controlling the operation / stop / rotational speed of the exhaust device, turning on / off the lamp, and the like on the front surface of the front plate.

[0003]

By the way, in the range hood fan, the lower end of the filter is evenly located at approximately 160 degrees from the floor.
It is stipulated by law that the height should be set to about 165 cm, and as a result, the front part is necessarily arranged at a high height. In addition, in the range hood fan of the type described above, the front plate is in the shape of a front bulge above the cooktop on which the combustion appliance is set. Therefore, when attempting to operate the operation unit while standing in front of the combustion instrument, the operation unit is blocked by the front plate and cannot be in the line of sight, which makes the operation difficult. Especially, it is difficult for a short person or an old person to reach with a finger, which makes the operation more difficult. In order to eliminate this, as shown in FIG. 7, a strip-shaped mounting plate 72 having a rearward inclination is fixed to the lower edge of the front plate 2 over the entire length in the width direction, and the strip-shaped mounting plate 72 is operated diagonally downward to the front. A range hood fan with 3 is already proposed. However, in this prior art example, the sink marks, which are spot welding marks on the front plate 2 of the strip-shaped mounting plate 72, are exposed to the inside of the room, impairing the interior quality, and complicating the assembly work. Further, in this range hood fan, a partition plate 82 is horizontally provided on the back surface of the front part 52 of the front plate 2 over the entire length in the width direction, and the electrical equipment part (switch) of the operation part 3 is housed inside the partition plate 82. The lower illumination 92 is attached using the partition plate 82. Therefore, there is a problem that the smoke trapping space is greatly reduced by the protrusion of the partition plate 82 in the entire width direction, and the smoke trapping efficiency is deteriorated.

The present invention has been made in view of the conventional circumstances, and its technical problem is to provide a narrow mounting means provided on the rear surface of the front surface of the front plate without exposing the fixing portion (such as the sink portion). A hood fan that supports the operation part on the lower edge of the front part of the front plate operably, secures a wide smoke trapping space, and can be easily operated by short people and the elderly without impairing the interior quality. To do. Still another technical problem is to provide a range hood fan having a simplified structure by also using the mounting means for mounting the operating portion as the mounting means for the lamp.

[0005]

Since the operating portion is directed forward or obliquely downward to the front, the operating portion is at a low position and is easy to see, and the operation is very easy. Therefore, even a short person or an old person can easily and nearby operate / stop / rotate the exhaust device and control the lamp. Moreover, since the mounting base has a narrow width for mounting and supporting the switch box, the volume protruding into the smoke trapping space is minimized, and the smoke exhaust efficiency can be improved. In addition, the fixed parts (spot welding, screws, rivets) of the mounting base are not exposed in the room, and when you stand in front of the cooktop, only the decorative edge is recognized together with the operation part, so the front plate The wide front part is exposed as a flat surface in the room, giving you an unprecedented simple and refreshing refreshing feeling, increasing the commercial value, and the switch box is hidden by the decorative edge even when operating, Become a range hood fan with a great looking look. (Claim 2) Furthermore, since the lamp case is mounted by using the mounting base which is the fixing means of the operating portion, it is not necessary to mount the lamp case by a separate mounting means, which simplifies the structure. Moreover, the cost can be reduced, and the smoke trapping space is not blocked by the partition plate that supports the lamp as in the conventional case, so that the smoke trapping efficiency can be improved. (Claim 5) Moreover, since the lamp cover of the lamp case mounted directly above the switch box is formed in a transparent arc shape in section, and the lamp is accommodated in the transparent lamp cover, the function is wide. Even if the range is illuminated evenly, and there are multiple burning appliances, the cooking (the steaming condition, the cooking condition, the baking condition, etc.) that is being performed in parallel with each burning appliance can be confirmed accurately, and the chopping board, etc. installed adjacently It makes it possible to perform deboning of fish, freshness confirmation, dish plattering, etc. under bright conditions, which greatly improves the workability of cooking, and its arcuate cross-section shape peculiarity prevents rise in smoke emissions. Since the lamp case can be kept low, there is no risk of reducing the efficiency of trapping smoke while the lamp case is provided on the back side of the front plate.
