Attach to the tip of the inner cord 30b.
[0005]
However, in the case of FIG. 7, the connector protrudes greatly on the top plate of the hood. Therefore, when installing the range hood, it must be attached in consideration of the protruding portion of the connector, which is inconvenient for installation and installation.
In addition, in the case of FIG. 8, the protruding problem in the case of FIG. 7 is solved, but since the connector is disposed close to the inner surface of the top plate, the male connector cannot be stably grasped and is connected and separated. It has a problem that it is difficult to rub.
In addition, since the range hood is installed above the stove, connector connection and disconnection work is performed with the line of sight facing directly above, and in such a state, the connector is inserted and removed vertically or horizontally. That is very inconvenient.
[0006]
The present invention has been made in view of the above-described problems of the prior art, and its purpose is not to hinder the installation and installation of the range hood, and to connect and disconnect the connectors in an easy posture. An object of the present invention is to provide a range hood having a wiring connection structure that can be easily performed.
[0007]
[Means for Solving the Problems]
The technical means taken by the present invention in order to achieve the above-mentioned object is that the top plate or the back plate of the hood main body having the front and lower surfaces opened, or one of the connectors connected to the cord outside the hood is connected to the hood. In addition to providing a connecting part that protrudes inward and is fixed in an inclined manner, the connecting part is provided so that the connector fixed to the part is inclined downward, and protrudes from the fan in the hood or the control panel. The other connector connected to the cord can be connected and disconnected in the hood.
Examples of the connector include a pin fitting type commonly used today, for example, a trade name “EL connector” manufactured by Nippon Crimp Terminal Manufacturing Co., Ltd.
[0008]
