A filter of a water purifying apparatus main body which is housed in a sink is made as a positive electrode, and a DC voltage is applied, by a dry battery cell, between the filter and a negative electrode in a purified water passage. Thus, microbes are prevented from proliferating in tap water which remains in the water purifying apparatus main body. A discharge pipe of the water faucet used exclusively for purified water is made as a negative electrode, and a DC voltage is applied, by the dry battery cell, between the positive electrode in the outlet of a cartridge and the discharge pipe. Thus, microbes are prevented from proliferating in tap water which remains in the water faucet used exclusively for purified water.

Water purifying apparatus

A water purifying apparatus of compact construction. The water purifying apparatus has a water channel for receiving water via an inflow passage and discharging water via an outflow passage. An electrically conductive filter is disposed in and fully occupies a portion of the water channel for purifying water flowing through the filter. A first electrode is electrically connected to the filter, and a second electrode, disposed in the filter, is electrically connected to the filter via water flowing through the filter. A battery supplies voltage between the first and second electrodes. A switch controls application of the voltage from the batteries to the first and second electrodes. A circuit board having a control circuit is disposed above the first electrode, the second electrode and the switch. The circuit board is electrically connected to the various electronic components.

A urine detection device is disposed to a urine receiving surface of a toilet stool in which urine, diluting water and reagent are mixed by vertically moving a piston in the cylinder of the detection device, the reaction between them is detected by an electrode and the ingredient in urine is detected. Liquid in the cylinder is stirred by a stirring device to blown air into the reagent reservoir, by which oxygen is dissolved in the reagent. Cleaning liquid is sprayed from the nozzle to the electrode for flushing. An opening is disposed to a supporting wall of the toilet stool, through which the cylinder is detached or attached. The electrode is disposed such that its rear end is directed to the opening and detached or attached through the opening.

Apparatus for detecting ingredient in urine, a toilet stool equipped

A sitting type water closet including a toilet bowl having an inner side and an outer side; a warm air duct for conveying warm air, formed on a first lower portion of the outer side of the toilet bowl as one piece therewith; a warm air outlet, disposed at an end of the warm air duct, for releasing warm air conveyed by the duct, the warm air outlet being at a mid position in the fore and aft direction of the toilet bowl and formed as one piece therewith; and a warm air guiding groove extending from the warm air outlet to the front of the toilet bowl, the warm air guiding groove being formed on a second lower portion of the outer side of the toilet bowl as one piece therewith.

An apparatus for examining urine for certain constituents thereof includes a vertically disposed cylinder for receiving urine therein. The cylinder includes a diametrically enlarged upper portion having an inside diameter which is larger than that of its remaining portion. A piston is vertically movably disposed in the cylinder. If the piston is lowered, urine can be stored in the cylinder. If it is raised, the urine is discharged from the cylinder, except that only a small portion thereof remains in a clearance defined between the piston and the diametrically enlarged portion of the cylinder. If the piston is lowered again, a reagent and water are supplied into the cylinder and mixed with the urine remaining therein. An electrode is connected to the cylinder for determining the concentration of sugar, etc. in the urine which has been mixed with the reagent and water. Disclosed also is a toilet stool having a bowl surface in which the upper end of the apparatus is exposed for receiving urine into the cylinder. The toilet stool including the apparatus can be employed to organize a system for collecting information on health. The system includes a first computer provided near the toilet stool for collecting data, such as the concentration of sugar in the urine, and transferring them, and a second computer which may be installed in a hospital for receiving the data from the first computer and storing them progressively.

System for collecting information on health

Multiway valve

A method and an apparatus for measuring the concentration values of constituents of urine collected in a toilet bowl. A conduit extends from the urine-collecting portion of the bowl to a concentration-measuring device. A gas injector is mounted beside the conduit to intermittently inject gas into the conduit, for dividing the urine contained in the conduit into aliquots. The concentration values of urinary constituents of each aliquot are measured.

Method and apparatus for detecting urinary constituents

A sitting type water closet, comprising a toilet bowl, a warm air path for conveying the warm air to a front portion of the bowl, and warm air outlet disposed in a front portion of the bowl. Further, a water closet unit capable of attaching the same to a toilet room and blowing warm air out, comprising: an adapter having a means for fixing the adapter to the toilet room, and a warm air generator; and a sitting type water closet having a warm air duct for conveying warm air from the generator to a space in front of the water closet; the water closet being attached at the rear portion thereof to the adapter, and furthermore, a prefabricated toilet room unit including the above water closet unit are also disclosed.

An apparatus for setting the ion concentration in an ionic water generator which separates drink water between alkaline ionic water and an acidic ionic water by applying a DC voltage between electrodes in an electrolytic cell which are partitioned by an ion-exchange membrane apparatus comprises a device for measuring voltage drop at a portion leading to the electrolytic cell which is caused when a reference voltage is applied, and a calculator for calculating voltage Vx which is applied to the electrolytic cell to adjust ion concentration to a desired value from a proportion k of the voltage drop which is calculated by application of the reference voltage to water to be examined relative to the reference voltage drop caused by application of the reference voltage to reference water and a set voltage Vn which corresponds to the desired ion concentration on the basis of the following equation:
