<p><P>PROBLEM TO BE SOLVED: To provide a range hood generating a warning when a cleaning work inside of the hood, or a work for detaching a fan of a blower from the hood is to be done while driving the blower, thereby prevent the works from being done when the blower is driven. <P>SOLUTION: This hood 1 includes a detachable protection member 5 (flow regulating plate 50) for keeping a person out of a suction opening 41 of the blower 4, and further includes a means (limit switch 60) for sensing release of the protection member 5, a means (operation switch 7) for detecting the driving of the blower, and a warning device (buzzer 80). The warning device is operated by the sensing signal of the sensing means and the detection signal so that the warning is generated when the cleaning work inside of the hood and the fan detaching work are to be done in a state that the blower is driven, to thereby prevent the execution of the works. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
