Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a range hood used for local ventilation for discharging oil smoke rising from a stove installed in a kitchen to the outside.

[0002]

2. Description of the Related Art In recent years, as a kitchen ventilation fan that discharges oil smoke generated during cooking, a range hood provided with a curtain plate that shields a space between the upper surface of the hood body and the ceiling surface has become the mainstream. . And, this range hood is required to have a simple structure and easy to construct.

A conventional range hood of this type will be described with reference to FIG. As shown in the figure, the butterfly bolt 102 is hooded in a hole provided on the top surface of the hood body 101 provided with an exhaust blower (not shown) having a box-like shape with an opened lower surface and a front surface. It is screwed from the inside of the main body 101 with the insertion curtain plate fixing bracket 103.

In the above structure, the insertion notch 104 of the curtain plate 105 provided with the notch 104 for insertion is inserted into the wing bolt 102 and tightened with the wing bolt 102, so that the hood body 101 and the curtain plate fixing bracket 103 are connected. It will be tightened and fixed to the hood body 101.

[0005]

In such a conventional range hood, the hood body 101 has a curtain plate fixing member 103.
It is necessary to sandwich and fix the curtain plate 105 by using the butterfly bolts 102, and the butterfly bolts 102 are tightened in an unreasonable posture from the inside of the hood body 101, which causes a problem that the construction is difficult to perform.

The present invention solves the above problems, and a first object thereof is to provide a range hood which can be easily installed, can be easily adjusted when the curtain plate is attached, and can reduce the number of parts.

A second object is that the construction can be performed easily, the curtain plate can be easily removed even during maintenance, and the curtain plate can be securely fixed.

[0008]

In order to achieve the above-mentioned first object, the range hood of the present invention comprises a hood main body having a box-like shape with an open bottom surface and an exhaust blower provided therein. A curtain plate that shields a space formed between the top surface and the ceiling surface of the hood body, a flange provided at a lower portion of the curtain plate, and a top surface portion of the hood body so that the flange is inserted. And a scale provided in the front and rear direction of the insertion gap so that the position of the flange inserted into this insertion gap can be visually checked, and the scale is abutted against the surface of the flange inserted into the insertion gap. The protrusion that holds the flange is provided on the hood body.

Further, in order to achieve the second object, the second
This means has a structure in which a mounting piece is formed on the curtain plate, and a leaf spring for sandwiching the mounting piece with the top plate is provided on the hood body.

[0010]

According to the present invention, with the construction of the above-mentioned first means, when the curtain plate is attached, the flange provided on the curtain plate is inserted into the insertion gap formed in the hood body, so that the projection shape provided on the hood body is formed. The portion comes into contact with the surface of the flange, the flange is held, and the curtain plate is attached to the hood body.

The front and rear positions of the curtain plate are determined by adjusting the position of the flange on the scale.

Further, according to the structure of the second means, by moving the curtain plate rearward on the top plate of the hood body, the mounting piece formed on the curtain plate resists the elastic force of the leaf spring and becomes a leaf spring. The curtain plate is attached by being inserted between the ceiling plate and the top plate, and when removing the curtain plate, it can be removed by moving the curtain plate forward.

[0013]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A first embodiment of the present invention will be described below with reference to FIG. As shown in the figure, an exhaust blower (not shown) is provided inside the box-shaped hood body 1 having an open bottom surface.
And a flange 3 is provided below the curtain plate 2 that shields a space formed between the top surface and the ceiling surface of the hood body 1, and the hood body 1 is inserted so that the flange 3 can be inserted.
When spotting the top plate 4, the step 5 is provided between the top plate 4 and the top plate 4 to form the insertion gap 6, and the insertion gap 6 is formed in the top plate 4.
The projection 7 is formed so as to be formed on the side, and the projection 7 comes into contact with the surface of the flange 3 inserted into the insertion gap 6 so that the flange 3 is held and the curtain plate 2 is attached.

Further, at the edge of the insertion gap 6 formed in the hood body 1, a position where the flange 3 of the curtain plate 2 is inserted can be visually observed, and a scale 8 is provided in the front-rear direction so that the position can be adjusted. Has been.

In the above structure, when the curtain plate 2 is attached, when the flange 3 formed on the curtain plate 2 is inserted into the insertion gap 6 formed on the hood body 1, the projection 7 comes into contact with the surface of the flange 3. The flange 3 is held and the curtain plate 2 is attached.

When the front and rear positions of the curtain plate 2 are adjusted, the position of the curtain plate 2 can be adjusted by aligning the position of the flange 3 with the scale 8 provided on the edge of the insertion gap 6.

Next, a second embodiment of the present invention will be described with reference to FIG. The same parts as those in the first embodiment are designated by the same reference numerals and detailed description thereof will be omitted.

As shown in the figure, the curtain plate 2a is provided with a mounting piece 9 projecting above the top plate 4a of the hood body 1a, and the top plate 4a is provided.
Is provided with a corrugated leaf spring 10 for elastically pressing the attachment piece 9 toward the top plate 4a.

In the above structure, when the curtain plate 2a is attached, by moving the curtain plate 2a rearward on the top plate 4a of the hood body 1a, the attachment piece 9 provided on the curtain plate 2a causes the elastic force of the leaf spring 10 to move. It is inserted between the leaf spring 10 and the top plate 4a against the force, the attachment piece 9 is sandwiched between the leaf spring 10 and the top plate 4a, and the curtain plate 2a is attached.

When the curtain plate 2a is to be removed, the mounting plate 9 of the curtain plate 2a can be detached from the leaf spring 10 by moving the curtain plate 2a forward.

[0021]

As is apparent from the above embodiments, according to the present invention, a flange is provided in the lower portion of the curtain plate, and an insertion gap into which the flange is inserted and a protruding portion for pressing the surface of the inserted flange and Since the hood main body has a scale on which the insertion position of the flange can be seen, the construction is easy when the curtain plate is attached, the position can be easily adjusted when the curtain plate is attached, and the range hood that reduces the number of parts is provided. it can.

Further, since the mounting piece is formed on the curtain plate and the leaf spring for sandwiching the mounting piece with the top plate of the hood main body is provided on the top plate, the construction at the time of mounting the curtain plate is easy. The curtain plate can be easily removed and installed during maintenance.
