摘要： PROBLEM TO BE SOLVED: To obtain a duct collector having high efficiency and compact construction by parallelly holding, in a casing, an ionization electrode, which is formed in the form of frame and in which a tapering protrusion in the form of an inner tooth is formed at an inner side edge, and a flat plate-shaped dust collecting electrode. SOLUTION: This dust collector includes a casing having a layered structure comprising three vertically stacked stages, and an electric circuit unit 21 is housed in a lower stage case 20, and a suction fan unit 32 in an intermediate stage case 30 is driven, while high DC voltage is applied into between a dust collecting electrode 31 held on the top surface of the intermediate stage case 30 and an ionization electrode 41 held in an upper state case 40. Thus, the air-containing dust is drawn into a framed hole of the electrode 41 to attach the dust to the electrode 31, to improve dust collecting efficiency. Further, ribs 46 are formed perpendicularly from a rear surface of ceiling wall of the case 40 and the ribs 46 is adapted to softly contact the upper surface of the electrode 31, and hence replacing sheets 50 for dust collecting placed on the upper surface of the electrode 31 are held and pressed.

摘要： PROBLEM TO BE SOLVED: To be provided with a porous filtering area provided with porous filter media having a specified diameter of pore diameter and filtering in accordance with the physical diameter, a high concentration of a chlorine area for allowing a high concentration of chlorine to elute and sterilizing, and a deodoring area housing a deodorant at a post-stage side more than a high concentration of the chlorine area on the device, and to enable to immediately supply drinking water with a single body. SOLUTION: A series of through-pathes are formed in a easing 20 of a portable water purifier 10, and non-filtered water is dissolved chlorine when it passes through a high concentration of the chlorine area 30 in this through path, and bacteria are sterilized and next the water passes through the deodoring area 40 and odor of chlorine like odor of bleaching powder is removed and at last passes through the porous filtering area 50 and the impurities in accordance with the particle size are filtered, thus raw water be easily filtered even at any place and drinking water be supplied.

摘要： PURPOSE: To provide a water purifier by which the purified water fitered by a filtration means is kept clean. CONSTITUTION: This water purifier 1 has first to third water purifying tanks 2 to 4, a casing, a water storage tank 29 set in the casing and a discharge pipe 7. When a microswitch is turned on by opening a lever switch 12, an intake pump 36 is started by a control circuit 44, and the water in the tank 29 is supplied and discharged from the pipe 7. Meanwhile, a control program is registered in the control circuit 44 to open the solenoid valve 27 of a pipeline 24 communicating with the tank 4 when the water filtered by the tank 4 is not used for a specified time (3hr in this example) to prevent the propagation of bacteria, to supply the water in the tanks 3 and 4 and pipelines 24, 28 and 35 to the tank 29 and to forcedly generate water.

摘要： PROBLEM TO BE SOLVED: To enable to easily secure drinking water even at a disaster time, etc., by pumping standing water, if it is present and filtering it, even in the case that city water can not be used. SOLUTION: A water intake hose 10 is connected with a water intake port 40a of a filter tank 40 as a city water introduction path, and a hand pump 20, for sucking water and pumping into the city water introduction path is attached to a water purifier connected a filtered water discharge path 50 with a discharge port of the filter tank 40, thus standing water can be purified at a time of stop of water supply, etc., and be made into drinking water and the water purifier be effectively utilized.
