Abstract
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.
