Abstract

PURPOSE:To improve the workability of a fixing work or a cleaning work by a method wherein some slits are arranged at lower portions of a main body of hood and a front hood and some fixing fitting of which attaching and removing may easily be performed are arranged at the slits. CONSTITUTION:A front hood 6 is installed to a main body 1 of a hood in such a way as at first an upper engaging claw 8a is engaged with an engagement piece 8b, a fitting 7b is manually moved in a direction toward a reduced diameter of a spring 7d to form a clearance between the fittings 7a and 7b. The fixing fitting 7 is inserted into slits 2a and 2b which are aligned at the lower portions while the main body 1 of the hood and the front hood 6 are inserted into this clearance. When a hand is released from the fittings while they are located at the deepest position, the fittings 7a and 7b may fasten and fix the main body 1 of the hood and the front hood 6 with a tension force of a spring 7d and then their insertion fittings can be completed. Then, removal of the front hood 6 from the main body 1 of the hood can easily be carried out under an opposite sequence of the operation of the insertion fitting operation. Therefore the workability in fixing work or cleaning is remarkably improved.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a range hood for exhausting oily smoke from a kitchen.

2. Description of the Related Art Conventionally, this type of range hood has generally had a construction as shown in FIGS. 6 and 7. That is, an electric motor 102 and blades 103 are placed inside a box-shaped hood body 101 with openings on the front and bottom surfaces.
The fan casing 104 has a built-in fan casing 104, fixing fittings 105a are melted on both sides of the inside of the hood body 101, and a front hood 106 is provided to cover the front surface of the hood body 101. A similar fixing fitting 106b is welded to the lower part of the front hood 106 so as to match the fixing fitting 105a, and in order to fix the hood main body 101 and the front hood 106, the fixing fittings 105a and 1015b are tightened with thumbscrews 107. It was fixed.

Problems to be Solved by the Invention In such a conventional configuration, during installation work or cleaning,
When attaching or detaching the front hood 106 from the hood main body 101, it is necessary to remove two thumb screws 107 and then tighten the thumb screws 107 when the work is completed, so it is not always easy to attach and detach the front hood 106. . When the casing was used for many years, it was extremely difficult to put it on and take it off, as oil dust etc. would pick up and clean it, and my fingers would slip when I tried to remove it.

The present invention solves these problems and provides a range hood that improves workability during installation work or cleaning by making it easy to attach and detach the hood body 101 and the front hood 106. The purpose is to

Means for Solving the Problems In order to solve this problem, the present invention provides a box-like hood body with openings on the front and bottom surfaces and a fan casing inside, and a box-like hood body with a fan casing provided inside the hood body. The hood main body and the front hood are locked at the upper part, each has nine slits at the lower part that match each other so that they abut each other, and the fixing metal fittings are inserted into and removed from the slits. It consists of a range hood that can be fixed freely.

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

EXAMPLE Hereinafter, an example of the present invention will be described based on FIGS. 1 to 4. In the figure, reference numeral 1 denotes a main body 7, which has a box-like shape with an open front and bottom surface, and has a fan casing 5 containing an electric motor 3 and blades 4 inside. A front hood 6 is provided to cover the front surface of the hood main body 1. The hood main body 1 and the front hood 6 have a locking claw 8a and a locking piece 8b at the top that lock each other, and an L-shaped strip at the bottom that fits together so as to abut each other. 2a and 2h are provided respectively. And Su! J7) 2a, 2
At bVc, the fixing fittings 7 are inserted and removed, and the front hood 6 is attached to and detached from the hood body. The fixing metal fitting 7 has a shaft 7C erected in the center of a circular metal fitting A7a, a circular metal fitting B7b movably provided on this shaft 7C, and a spring extractor provided at the opposite end of the shaft 7C from the metal fitting A7a. Stopper 7e and metal fitting B
A spring 7d is provided between the spring 7b and the spring 7b.

In the above configuration, when installing or cleaning the front hood 6, the front hood 6 is attached to the hood body 1 by first locking the upper locking claw 8a and the locking piece 8b, and then attaching the matching screws at the bottom. g) Insert the fixing metal fittings into 2a and 2b. This insertion is performed by manually moving the metal fitting Byb in the direction of the spring 7d contraction to form a gap between the metal fitting A7a and the metal fitting Byb, and inserting the hood main body 1 and the front hood 6 into this gap, and then inserting the fixing metal fitting 7. s') ノ) 2 a and 2 b, and when you release your hand when it is fully inserted, the metal fitting A will open.
7 a.

7b tightens and fixes the hood main body 1 and the front hood 6 by the tension of the spring 7d, and the wearing is completed.

Next, the front hood 6 can be easily removed from the hood main body 1 by performing the above-mentioned mounting operation in the reverse order.

Effects of the Invention As described above, according to the present invention, the front hood can be easily attached to and detached from the hood body by inserting and removing the fixing fittings into the slit provided at the bottom, which improves the workability of installation work and cleaning. The effect of this is that the results are significantly improved.
