[0003] As described in Japanese Patent Application Laid-Open No. 4-36530, while the smoke and the like generated during cooking are sucked and discharged many times by the above-mentioned blower, the inner surface of the hood 1 becomes very dirty. In this case, the cleaning is made as easy as possible. A joining surface 4 is formed on the periphery of the opening on the front surface of the hood main body 2, and the left and right upper portions of the joining surface 4 are respectively engaged. A hole 5 is formed, and a fixing portion 7 having a groove 6 is formed at a lower portion.

On the other hand, a joining surface 8 is formed at the peripheral edge of the opening on the back of the front hood 3, and approximately rhombic (see FIG. 18) leaf springs 9 are provided on the right and left upper portions of the joining surface 8. , A fixing portion 11 having a groove portion 10 at a lower portion is formed.

[0005] With this configuration, the leaf spring 9 of the front hood 3 is pressed into the engagement hole 5 of the hood main body 2 and engaged therewith.
To the fixing part 11. Then, the substantially dumbbell-shaped fixing device 12 shown in FIG. 19 is fitted into the groove portions 6 and 10 where the fixing portions 7 and 11 match. Thus, the front hood 3 is attached to the hood main body 2, and the front hood 3 is detached from the hood main body 2 in the reverse operation. Therefore, when the inner surface of the hood 1 becomes very dirty, the front hood 3 is removed from the hood main body 2, and in this state, the inner surface of the hood main body 2 and the inner surface of the front hood 3 may be cleaned.

In addition, when the front hood 3 is attached to the hood main body 2, the fixing tool 12 is positioned such that the above-mentioned oil smoke or the like is sucked by the blower in the hood main body 2 and is exposed on a path passing through the hood 1. Therefore, the fixing tool 12 itself becomes dirty with oil smoke or the like, and the sticking thereof makes it impossible to easily remove the fixing tool 12, and hence the front hood 3 from the hood main body 2 cannot be easily removed. In addition, there is a problem that the fixture 12 must be cleaned one by one.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned circumstances, and an object of the present invention is to easily attach and detach a front hood to and from a hood body without troublesome attachment and detachment of attachment parts. Provided is a range hood that can eliminate the risk of losing the mounting parts, can easily and sufficiently clean the inner surface of the hood body, and can reduce the problem of contamination of the mounting parts. Another object of the present invention is to provide a range hood which can prevent the problem of oil dripping.

[0009]

In order to achieve the above object, a range hood according to the present invention is provided with a blower therein, a lower surface and a front surface are opened, and a joining surface is formed on a peripheral portion of the opening on the front surface. And a hood body having an engagement hole formed at an upper portion of the joining surface portion, and an inner edge of the joining surface portion being substantially flush with an inner end edge of the hood body on both inner side surfaces of the hood body. An inner cover provided so as to cover the respective surface portions, and an inner cover attached to the inner cover, protruding from a lower portion of the joining surface portion of the hood main body, and having an engaging projection at the projecting portion. An engaging body made of an elastic material operably provided to release the engagement, and a lower surface and a rear surface formed with an opening, and a joining surface joined to a joining surface portion of the hood body formed at a peripheral portion of the opening at the back surface. And the above-mentioned An engaging projection which is inserted and slidably engaged in a locking hole of the locking body is provided at a lower portion of the joint surface, the engaging projection of the locking body being engaged by elasticity of the locking body. And a front hood having a hole formed therein (the invention of claim 1).

According to this structure, the engaging projection of the front hood is inserted into the engaging hole of the hood body and engaged by sliding, and the engaging hole is engaged with the engaging projection of the engaging body. The front hood can be attached to the hood main body by engaging with the elasticity of the hood, and the front hood can be removed from the hood main body by the reverse operation. There is no need for installation and removal.

Further, cleaning of the inner side surface of the hood body only requires wiping and cleaning the inner surface portion of the inner cover in a state where the front hood is removed, and there is no need to clean the back surface or the corner of the joint surface. . Furthermore, the locking body, which is a component for mounting the front hood, is covered with an inner cover on the path through which the oil smoke and the like are drawn by the blower in the hood body and passes through the hood, so that the attachment of the oil smoke and the like is avoided. Can be

In this case, the hood body has a filter,
It is preferable to have a locking member on the blower side of the filter (the invention of claim 2). In this case, air from which oil smoke and the like have been removed by the filter comes into contact with the locking member, and the oil smoke and the like adhere to the locking member even further.

It is preferable that at least the inner surface of the inner cover is made of a water-repellent / oil-repellent material. In this case, it is possible to easily wipe off dirt attached to the inner surface of the inner cover. In addition, it is preferable that the inner cover has a bead extending substantially horizontally at the lower portion (the invention of claim 4). In this case, the oil stain adhering to the inner cover and flowing down can be stopped with a bead so that it does not easily drop down.

The hood main body has a bent portion extending substantially horizontally with a U-shaped cross section at a lower portion of both side portions, and an inner cover has a bent portion extending substantially horizontally with an L-shaped cross section at a lower portion. It is also possible to have a curved portion and combine them (the invention of claim 5). In this case, an oil stopper having a larger protrusion amount than the bead can be formed at a lower portion of the inner surface portion of the inner cover,
Accordingly, oil stains that adhere to the inner cover and flow down can be prevented from dripping more easily.

Further, the edge of the bent portion of the hood main body is made higher than the edge of the bent portion of the inner cover, and the edge of the bent portion of the hood main body is folded back toward the inner cover to overlap. (The invention of claim 6). In this case, the oil stain adhering to the inner cover and flowing down can be accumulated in the lower portion of the inner surface of the inner cover, and the dripping of the oil stain can be more reliably prevented. Also, in this case,
By folding and overlapping the edge of the bent portion of the hood body toward the inner cover, no sharp edge remains above the edge of the bent portion of the inner cover, which can eliminate the risk of injury to the user. .

The bent portion of the inner cover may be formed in a L-shaped cross section instead of an L-shaped cross section (claim 7). In this case, it is easy to clean the portion where oil dirt is stored.

In addition, both inner side surfaces of the front hood are provided with inner covers for respectively covering both inner side surfaces of the front hood, and the projections of the locking members are inserted into the inner covers of the front hood. In this case, it is preferable to form an operation hole in the inner cover of the hood main body for performing an operation of releasing the engagement of the engagement projection of the locking body (the invention of claim 8).

In this apparatus, the inside surface of the front hood can be cleaned by removing the front hood from the hood body.
It is only necessary to wipe and clean the inner surface of the inner cover, and there is no need to clean the back surface or the corner of the joint surface. In addition, in this case, when the front hood is attached to the hood body, the protrusion of the locking body is located inside the inner cover of the front hood, so that it is impossible to operate the protrusion of the locking body. However, since the operation of releasing the engagement of the engagement projection of the locking member can be performed from the operation hole of the inner cover of the hood main body, the ease of removing the front hood is not impaired.
