Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a range hood for exhausting oily smoke in a kitchen.

2. Description of the Related Art Conventionally, this type of range hood generally has a configuration as shown in FIGS. That is, a box-shaped hood body 101 having an opening on the front surface and a bottom surface has a fan casing 104 having an electric motor 102 and blades 103 built-in, and fixing metal fittings 105a are welded to both inner lower sides of the hood body 101. A front hood 106 is provided so as to cover the front surface of the main body 101,
A similar fixing bracket 105b is welded to the lower part of the front hood 106 so as to match the fixing bracket 105a of the hood body 101, and in order to fix the hood body 101 and the front hood 106, the fixing brackets 105a and 105b are thumbscrews. It was tightened and fixed with 107.

Problems to be Solved by the Invention With such a conventional configuration, when the front hood 106 is attached to or detached from the hood body 101 during installation work or cleaning, the two thumbscrews 107 are removed, and when the work is completed, the knob is removed. You have to tighten the screw 107,
It was not always easy to put on and take off. In addition, when it was used for many years, oil dust and the like adhered to the knob, and the finger slipped when removing it, making it very difficult to attach and detach.

The present invention solves such a problem, and provides a range hood in which workability in installation work or cleaning is improved by facilitating attachment / detachment of the hood body 101 and the front hood 106. The purpose is.

Means for Solving the Problems In order to solve this problem, the present invention provides a hood main body of a box body having front and lower surfaces opened and a fan casing provided inside, and a hood main body provided so as to cover the front surface of the hood main body. The hood main body and the front hood are engaged with each other at the upper part, and each has a matching slit in the lower part, which is in contact with each other. It is a structure of a range hood.

Operation With this configuration, the hood main body and the front hood can be easily attached / detached by inserting / removing the fixing metal fittings into / from the slits during installation work or cleaning.

EXAMPLE An example of the present invention will be described below with reference to FIGS. In the figure, reference numeral 1 denotes a hood body, which has a box-like shape with its front and bottom surfaces opened, and has a fan casing 5 having an electric motor 3 and blades 4 built therein. A front hood 6 is provided so as to cover the front surface of the hood body 1. The hood body 1 and the front hood 6 have locking claws 8a and locking pieces that are locked to each other at the upper part.
8b, and L-shaped slits 2a, 2b of the same shape are provided on the lower part, which are fitted to each other and are in contact with each other. Then, the fixing metal fitting 7 is inserted into the slits 2a and 2b,
After being removed, the front hood 6 is attached to and detached from the hood body. As for the fixing metal fitting 7, a shaft 7c is erected in the center of a circular metal fitting A7a, a circular metal fitting B7b is movably provided on the shaft 7c, and a spring retaining member provided at an end portion of the shaft 7c opposite to the metal fitting A7a. 7e
And a metal fitting B7b between them and a spring 7d.

In the above configuration, when installing or cleaning
To attach the front hood 6 to the hood body 1, first, the upper engaging claws 8a and the engaging pieces 8b are engaged, and the fixing metal fittings are inserted into the slits 2a, 2b which match the lower parts. In this insertion, the metal fitting B7b is manually moved in the direction of contraction of the spring 7d to form a gap between the metal fitting A7a and the metal fitting B7b, and the hood main body 1 and the front hood 6 are inserted into the gap and the fixing metal fitting 7 is inserted. Is inserted into the slits 2a, 2b, and when the hands are released at the deepest position, the metal fittings A7a, 7b are clamped and fixed so that the hood body 1 and the front hood 6 are clamped by the tension of the spring 7d, Insertion is completed.

Next, the front hood 6 can be easily detached from the hood body 1 in the reverse order of the above-mentioned wearing operation.

As described above, according to the present invention, the front hood can be easily attached to and detached from the hood main body by inserting / removing the fixing metal fittings into / from the slits provided in the lower portion. Since the hood body and the front hood are provided with the slits of the same shape, the structure is simple and the cost is low as compared with the case where parts of different shapes are used.
