STOOL-TYPE FLUSH TOILET SYSTEM HAVING SUBSTANTIALLY ELLIPTICAL DONUT-SHAPED ROTARY TOILET SEAT

PROBLEM TO BE SOLVED: To solve problems in a toilet system where a conventional rotary toilet seat is rotated by θ degrees from a defecating reference position S and confronts a non-contact automatic hand washing device arranged in a distance L from a rotation center D of the rotary toilet seat in a washing position F, the system that has a large rotating mechanism, has a high cost and a heavy load, is not hygienic and is not convenient.SOLUTION: A toilet system is achieved as follows: a load is supported by light weight and inexpensive bearings or ball casters; a rotary toilet seat is installed in the upper part of a rotating mechanism with a contamination prevention wall; the toilet seat is made into a donut-shaped rotary toilet seat having a substantially elliptical inner hole to be easily seated and facilitate excretion; a cover is put on an insanitary portion of a porcelain bowl tip to prevent clothes from being caught therein; a rotation angle θ degree is controlled by a rotary toilet seat stopper leaf spring and a rotary limit rod; and thereby the system is hygienic and convenient to effectively prevent infestation of infectious harmful bacteria.SELECTED DRAWING: Figure 1 【課題】従来の回転便座は、排便を行う基準位置Ｓからθ度回転し、洗浄位置Ｆで回転便座の回転中心Ｄから距離Ｌに配置した非接触自動手洗い装置と正対するトイレシステムにおいて、回転機構が大型で、高価、重量物で、衛生的でなく、使い勝手の悪い問題があった。【解決手段】軽量、安価な軸受ベアリングか、または、ボールキャスターで荷重を支え、汚染防止壁を備えている回転機構の上部に回転便座を設置し、便座を略楕円内穴を持つドーナツ形状の回転便座にして、座り易く、排泄もし易くし、陶製便器先端の不衛生な部分にカバーを掛け、回転しても衣服の巻き込みが無く、回転便座ストッパー板バネと回転リミット棒で回転角度θ度を制御し、衛生的で使い勝手が良く、感染性有害細菌の蔓延を効果的に防止するトイレシステムを実現した。【選択図】 図1
