TOILET SEAT DEVICE

To provide a toilet seat device which uses a filter while switching it between two filters including a photocatalyst filter with a simple configuration to enhance deodorization efficiency and improve a service life of the filter.SOLUTION: A deodorization device of a toilet seat device comprises: a channel having a first channel in which a first filter including a photocatalyst is arranged and a second channel in which a second filter different in kind from the first filter is arranged and whose pressure loss is greater than that of the first channel, the first channel and the second channel being provided in parallel therein; a lamp for radiating light to the photocatalyst; a fan for blowing air; and a storage tank which can store the first filter and water. The toilet seat device comprises: a water feeding part for feeding water to the storage tank; and a control part for performing first deodorization control for making air circulate in the first channel in a state where the storage tank doe not store water to perform deodorization by the first filter, and second deodorization control for making air circulate in the second channel in a state of suppressing circulation of the air in the first channel while storing water in the storage tank so that the first filter is immersed in the water, to perform deodorization by the second filter.SELECTED DRAWING: Figure 2 【課題】光触媒フィルタを含む２種類のフィルタを簡易な構成で切り替えながら使用して、脱臭効率を高めつつフィルタの長寿命化を図る。【解決手段】便座装置の脱臭装置は、光触媒を有する第１フィルタが配置された第１流路と、第１フィルタとは種類の異なる第２フィルタが配置され第１流路よりも圧力損失が大きい第２流路とが内部に並列に設けられた流路と、光触媒に光を照射するランプと、送風するファンと、第１フィルタを収容すると共に貯水可能な収容槽とを備える。便座装置は、収容槽に給水する給水部と、収容槽に貯水していない状態で第１流路に空気を流通させて第１フィルタで脱臭する第１脱臭制御と、第１フィルタが水に浸漬するように収容槽に貯水させて第１流路の空気の流通を抑制した状態で第２流路に空気を流通させて第２フィルタで脱臭する第２脱臭制御とを実行する制御部とを備える。【選択図】図２
