<P>PROBLEM TO BE SOLVED: To minimize decrease of an amount of ions caused by presence of an ion measurement apparatus in measuring the amount of ions emitted in an electrical apparatus with an ion emission function. <P>SOLUTION: The electrical apparatus with an ion emission function is provided with an ion generating device 2 generating ions by discharging in the air, and a draft air duct 1 and an air blower for sending out an air stream containing the ions generated from the ion generating device 2. A bypass passage 3 is formed contiguous to the draft air duct 1, and an ion measurement apparatus 10 and a valve device 6 are arranged in the bypass passage 3. Thus, it is selectable by opening/closing the valve device 6 whether or not making a part of the air stream flowing in the draft air duct 1 flow into the bypass passage 3. The valve device 6 includes an inlet valve 7 and an outlet valve 8. The ion measurement apparatus 10 consists of a collector electrode 11 and a repulsion electrode 12 which are arranged opposite to each other. <P>COPYRIGHT: (C)2012,JPO&INPIT |
