A toilet flush water supply device for supplying flush water to a flush water tank of a flush toilet is disclosed. The toilet flush water supply device comprises a water supply pipe connected to an external water supply source, a water supply valve for switching between spouting and stopping of flush water supplied from the water supply pipe into the flush water tank, a float for switching between the spouting and stopping of the above water supply valve by a vertical movement thereof linked to fluctuations in the flush water level within the flush water tank, and a float guide disposed on the outer surface of the water supply pipe for guiding the vertical motion of the float.

A toilet device with a system for inspecting the health condition of the toilet user includes a toilet having a bowl surface with a urine reservoir for holding a urine sample, a box having at least a water tank disposed rearwardly and upwardly of the toilet, the box having an outlet opening in a bottom thereof, a slider for holding a urine test paper piece, the slider being movable from within the box toward the urine reservoir to immerse the urine test paper piece in the urine sample in the urine reservoir, a urine analyzing device disposed in the box, for analyzing constituents of the urine sample attached to the urine test paper piece, a lifting and lowering mechanism for reciprocally lifting and lowering the slider through the outlet opening along a substantially vertical inclined path between the urine analyzing device and the urine reservoir, and a display panel for controlling the lifting and lowering mechanism and the urine analyzing device and for displaying results of a urine analysis effected by the urine analyzing device.

A washing device for parts of human body comprises a thermostatic mixing valve which is disposed at a junction of a cold water supply passage and a heated water supply passage, a latching solenoid valve which is mounted on a heated water drainage passage branched out from said heated water supply passage and a latching solenoid valve which is mounted on a mixed hot water supply passage. Due to such construction, electric power for heating water is no longer necessary in the toilet bowl and electric power for mixing heated water and cold water to produce mixed hot water to be ejected from an ejecting nozzle also becomes unnecessary. Furthermore, electric power for operating the solenoid valve is minimized by means of a latching solenoid. Accordingly, the overall consumption of electric power necessary for operating and controlling the washing device can be minimized thus enabling the use of a small dry cell or battery as an electric power source of the washing device.
