<p>The invention provides; a flush toilet having an odor-sealing valve which can certainly be opened and closed with a simple structure and enables easy maintenance, capable of preventing waste matter adhering on it from facing toward the toilet bowl, and effectively working when a patient unintentionally defecates; a care bed apparatus which reduces physical work load on a nurser when bathing the patient; and others. A water tank (52) is provided below a toilet bowl (51), and an odor-sealing valve (57) is made of a sphere (57a) floating in the water tank (52) and a ring-shaped packing (57b) located near a lower opening (51a) of the toilet bowl (51) and capable of coming in close contact with said sphere (57a). Drainpipes and drain valves (66a, 67a, 66b, 67b) lower the water level in the water tank (52) to open the odor-sealing valve (57) and a water-supply pipe (64a) and a water-supply valve (64b) raise the water level in the water tank (52) to close the odor-sealing valve (57). The odor is evacuated as shown by the arrows (Fa) and cleaning water flows down onto the sphere (57a) as shown by the arrows (Fw) to clean away waste matter (S) and to turn the sphere. <IMAGE></p> |
