PROBLEM TO BE SOLVED: To stabilize an amount of liquid supplied to evaporation means as much as possible, when simultaneously performing humidification, sterilization and deodorization, so as to uniform the humidity of a vaporized liquid generated in the evaporation means.SOLUTION: A spatial sterilization device comprises: a housing a gas flow channel which is provided to the housing blowing means which is provided in the midway of the gas flow channel and generates air flow evaporation means which is provided to the gas flow channel and vaporizes a liquid and antibacterial agent housing means for housing an antibacterial substance carrier in which antibacterial substance is absorbed. The evaporation means comprises a liquid carrier 8 having permeability and a liquid-retaining property, and liquid supply means for supplying a liquid L to the liquid carrier. The liquid supply means includes a liquid supply path 14 for supplying the liquid to the liquid carrier. An accumulator 16 for expanding the liquid supply path is provided in the portion opposed to the liquid carrier of the liquid supply path, and a liquid discharge hole 15 for supplying the liquid to the liquid carrier is formed in the accumulator.COPYRIGHT: (C)2015,JPO&INPIT【課題】加湿作用と除菌消臭作用とを同時に行なう際に、気化手段に供給される液体の供給量を極力安定させ、これによって、前記気化手段において生成される気化液の湿度をより均一にすることを課題とする。【解決手段】筐体と、筐体に設けられた気体流路と、この気体流路の途中に設けられ、気流を発生させる送風手段と、気体流路に設けられ、液体を気化させる気化手段と、抗菌性物質が吸着された抗菌性物質坦持体を収納する抗菌剤収納手段とを備え、気化手段が、通気性および保液性を有する液体坦持体8と、この液体坦持体に液体Lを供給する液体供給手段とによって構成され、この液体供給手段が、液体を液体坦持体へ供給する液体供給路14を備え、液体供給路の液体坦持体と対峙する部位に、液体供給路の流路を拡大するアキュムレーター16が設けられ、このアキュムレーターに、液体を液体坦持体に供給する液体吐出孔15が形成されている。【選択図】図13
