Abstract

PROBLEM TO BE SOLVED: To provide a simple range hood having a filter for treating an oil mist therein and including new shape and structure which can be easily handled, in which an inner oil liquid treatment or filter cleaning can be extremely simply executed and which has a functional beauty together. SOLUTION: The range hood comprises an opening, a cylindrical filter, a curved opening/closing board for blocking the opening in a state in which the filter is inserted into a central part, and a blind-cum-oil tray provided at a lower part of the filter. Thus, the oil liquid therein can be externally treated.

Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a filter device for treating oil smoke in a range hood installed in a kitchen.

[0002]

2. Description of the Related Art The inside of a range hood is mainly composed of a centrifugal fan, an exhaust duct and the like, but it was inevitably formed into a large box shape because of the necessity of collecting oily smoke widely. Therefore, the oil smoke guided inside spreads and an important device becomes covered with oil. To prevent this, it was common to install a large filter in the hood or in the opening.

[0003]

However, from the user's point of view, the built-in type filter is very troublesome to remove and install by opening the lid of the hood, and since the opening type is bulky, it is not easy to wash. It also had the drawback of not being visually pleasing. Further, even when treating the oil receiving tray in the hood, the work in which the opening / closing board and the filter are removed is most disliked. Users (mainly housewives) do not want to put their hands in the hood as much as possible.

[0004]

In order to solve these problems, according to the invention according to claim 1, the board shape for concentrating the oil smoke makes it possible to open the suction port small.
Therefore, it is possible to equip the suction port according to the invention of claim 2 with a compact hierarchical filter. According to the invention of claim 3, the oil liquid inside is automatically guided to the filter device without opening the hood.

[0005]

BEST MODE FOR CARRYING OUT THE INVENTION The filter of the present invention is a system in which oil smoke is treated at the suction port before it spreads inside the hood, but it is not necessary to cover the entire front face with a large filter as in the conventional case. Due to the shape of the opening / closing board of the present invention, even if the suction port is small, its effect is not affected to a small extent, and the oil receiver also serving as a blindfold is mounted with a shape beauty integrated with a compact hierarchical filter. It is something.

Since the area of the filter is small, the effect is exhibited by the method of stacking the number of sheets. Depending on its form,
Instead of wiping and cleaning like a conventional filter, the effect is completely restored because it is soaked in detergent etc. Therefore, it is basically a type that is used while being exchanged, and you can perform filter processing without touching the oily part.

The oil liquid accumulated inside is guided and naturally flows into the above-mentioned filter portion, and is accumulated in the oil receiver below. Therefore, all the processing of oil and oil smoke is concentrated in the filter section and is performed from the outside of the hood.

[0008]

Embodiments Embodiments will be described with reference to the drawings. According to FIG. 1, the rising oil smoke goes toward the suction port B-3 along the opening / closing board B-2. Then, the smoke is collected in the filter part A inserted into the suction port. The entire filter portion has a shape in which a plurality of filters A-3 are stacked on the cylindrical frame A-2, and an oil receiver A-5 is provided on the lower portion by an axis A-4 to form an integrated structure. To attach to the opening / closing board B-2, it is fixed from the outside by inserting it, screwing it in, and clicking.

The oil liquid is guided to the passage D-2 from the oil sump D under the centrifugal fan C inside the hood B, passes through the pipe A-6 in the center of the cylinder frame A-2, and the lower oil receiver A is provided. Stored at -5.

[0010]

[Effect] Conventionally, the biggest problem of the range hood is the oil stain inside, but the filter that processes the oil smoke at the entrance does not spread the stain to the whole, and the shape without the large internal filter is achieved. In addition, cleaning the hood is much easier.

Further, even when cleaning the filter itself, it can be soaked and washed for easy handling. It is free from the most disliked work of opening the lid and taking out a large oily filter inside to wash it. .

Since the opening is blocked by the structure of the opening / closing board and the filter portion of the present invention, it is not necessary to equip the duct inside the hood with a shutter, a windproof plate and the like, and the appearance is improved. It is a range hood that is much simpler and more economical than a hood.

Claims (3)

[Claims] 1. In a range hood for exhausting oil smoke or the like in a kitchen, the entire front part which receives the oil smoke is closed by forming a gentle arch-shaped recess toward the center, and the caliber is formed with the apex of the recess as a base point. Is a range hood that is equipped with an opening and closing board with an opening of about 5 to 10 cm, and the filter part is attached to the opening by screwing or inserting. 2. The filter for closing the opening according to claim 1, wherein a cylindrical frame in which a plurality of filters are hierarchically included, and a filter integrally formed by equipping a lower part with an oil receiver also serving as a blind are provided. A range hood characterized by being attached to an opening / closing board. 3. A range hood characterized in that a passage through which an oil liquid flows from an oil sump inside the hood is guided to the filter portion and dropped into an oil receiver below the filter.
