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 Heretofore, this type of range hood has generally been constructed 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.

SUMMARY OF THE INVENTION With such a conventional configuration, when attaching or detaching the front hood 106 to or from the hood body 101 during installation work or cleaning, the thumbscrews 107 are removed in two places, and the thumbscrew is removed when the work is completed. You have to screw 107
It was not always easy to put on and take off. In addition, when used for many years, oil dust and the like adhered to the thumb screw 107, and the finger slipped when removing it, making it very difficult to attach and detach. There is also a problem that the thumbscrew 107 may be lost during work.

The present invention is to solve such a problem, by facilitating the attachment and detachment of the front hood to the hood body,
It is an object of the present invention to provide a range hood which improves workability during installation work or cleaning and prevents loss of a thumb screw for fixing the hood body and the front hood.

Means for Solving the Problem In order to solve the problem, the present invention relates to a hood main body of a box body having front and bottom surfaces opened, a fan casing provided inside the hood main body and having an electric motor and blades, and the hood. A front hood that covers the front surface of the main body, and at the lower front portion of the hood main body, a fixing metal fitting consisting of a shaft having stoppers on both sides is movably held, and the end of the horizontal portion is the shaft of the fixing metal fitting. An inverted L-shaped hood body slit having a width smaller than the outer diameter is formed, and when the front hood is installed on the front surface of the hood body, the width in the vertical direction is the same at a position matching the hood body slit. The range hood is provided with an inverted L-shaped front hood slit having a width larger in the horizontal direction than the retaining of the fixing bracket.

Operation With this configuration, to attach the front hood to the hood body, the fixing metal fitting should be positioned in the horizontal part of the hood body slit, and the front hood should pass through the horizontal part of the front hood slit so that the fixing metal fitting does not come off. Cover the front of the hood body, then move the fixing bracket to the vertical part of the hood body slit and the front hood slit to complete, and to remove it, reverse the above order. The front hood can be easily attached and detached, and since the end of the horizontal portion of the hood body slit is smaller than the shaft, the fixing bracket is always held by the hood body.

Embodiment An embodiment 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 has a reverse L-shaped hood body slit 2a which has the same direction in the lower portion which has the same shape.
And a front hood slit 2b is provided. As shown in FIG. 3, the hood body slit 2a has an opening at the end of the horizontal portion which is narrower than the other portions, and a fixing metal fitting 7 described in detail below is movably and externally provided in the slit. It is held so that it cannot come out. As shown in FIG. 5, the fixing metal fitting 7 has a shaft 7c at the center of a circular metal fitting A7a for retaining.
, A circular metal fitting B7b is movably mounted on the shaft 7c, and a spring 7d is inserted between the spring retainer 7e and the metal fitting B7b provided on the end of the shaft 7c opposite to the metal fitting A7a. Is configured. This fixing metal fitting 7 is attached to the hood body slit 2a by attaching the metal fitting A7a and the metal fitting B7b to the spring when assembling the range hood.
A shaft that appears in the gap by pushing out against the tension of 7d
This is achieved by pressing the 7c into the narrow opening of the hood body slit 2a so as to widen the part, and is normally held in the slit.

The front hood slit 2b has the same width in the vertical portion as the hood body slit 2a, but has a large horizontal portion and is formed wider than the outer diameter of the metal fitting 7a of the fixing metal fitting 7.

In the above configuration, when mounting the range hood or cleaning, the front hood 6 is attached to the hood body 1 by first engaging the upper engaging claws 8a and the engaging pieces 8b, and then matching the lower parts. The hood body slit 2a and the front hood slit 2b are vertically attached to the hood body slit in advance.
The fixing metal fitting 7 located at the horizontal portion of 2a is moved and inserted. To insert this, pull the metal fitting A7a to the front side by hand and
Is moved in the direction of shortening the spring 7d to form a gap between the metal fitting A7a and the metal fitting B7b. With the hood body 1 and the front hood 6 inserted in this gap, the shaft 7c of the fixing metal fitting 7 is inserted into the hood body slit 2a. Insert it along the vertical part of the front hood slit 2b, and release the hand when it reaches the bottom, and this operation causes metal fittings A7a and metal fitting B7b to spring.
The hood body 1 and the front hood 6 are tightened and fixed by the tension of 7d, and the wearing 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.

EFFECTS OF THE INVENTION According to the present invention as is apparent from the above description of the embodiments, the front hood can be easily attached to and detached from the hood main body by moving the slit provided in the lower portion of the fixing bracket. The workability of installing or cleaning the range hood is remarkably improved, and since the fixing metal fittings are always held by the hood body, it is possible to prevent the loss of loss when the front hood is removed.
