A negative ion generating air cleaner comprising a power adapter (21), at least two voltage generators (22), and at least two discharge ends (23), the first input end of the power adapter (21) The second input terminal is connected to the neutral line (N) of the AC commercial power supply, and the third input terminal is connected to the ground line (E) of the AC commercial power supply , The power adapter (21) converts the AC voltage input from the first input terminal and the second input terminal into a DC low voltage, and outputs the DC low voltage for each of the high voltage generators (22) Each of the high voltage generators (22) further converts the DC low voltage output from the power adapter (21) into a DC high voltage and outputs it, and the first output of each high voltage generator (22) The anode end of which is connected to at least one discharge end (23) solely via a high voltage line and the second output end is connected to a reference ground which is a negative ion generation type air cleaner ground, negative ion generation type air cleaning We disclose vessel. As described above, it is possible to guarantee that the length of the high voltage line becomes the shortest, the power lost in the circuit becomes the smallest, the burnout is hard to be brought down, and the requirement in the design process is reduced, Reduce complexity with raw materials.電源アダプタ(21)と、少なくとも二つの電圧発生器(22)と、少なくとも二つの放電端(23)とを備える負イオン発生型空気清浄器において、電源アダプタ(21)の第一の入力端は交流商用電源の活線(L)に接続され、第二の入力端は交流商用電源の中性線(N)に接続され、第三の入力端は交流商用電源の接地線(E)に接続されており、電源アダプタ(21)は第一の入力端と第二の入力端から入力される交流電圧を直流低電圧に変換し、そして直流低電圧を高電圧発生器(22)毎に出力して、高電圧発生器(22)の各々はさらに電源アダプタ(21)から出力される直流低電圧を直流高電圧に変換して出力し、高電圧発生器(22)毎の第一の出力端は高電圧線を介して単独で少なくとも一つの放電端(23)に接続され、第二の出力端は負イオン発生型空気清浄器アースである基準アースに接している負イオン発生型空気清浄器を開示する。上記のようにして、高電圧線の長さが最も短くなり、回路で損失される電力が最も小さくなり、焼損しにくくなることを保証できるとともに、設計プロセス上の要求を低減して、生産に原料を備える複雑性を低下させる。
