Abstract

PROBLEM TO BE SOLVED: To provide a simple table water cleaner high in water cleaning capacity, dispensing with the replacement of a filter medium and not bringing about the propagation of bacteria, fungi or the like. SOLUTION: This table water cleaner consists of an almost cylindrical container 1 having an opening part formed at the upper part thereof, the lid 2 covering the opening part of the container 1, activated carbon 3, a pair of fabrics or nets 4 for holding activated carbon, the piston 5 holding activated carbon 3 and the fabrics or nets and having water passing hole parts, the rod 8 bonded to the central part of the piston 5 to slide in the hole part 7 formed at the central part of the lid 2 and the handle part 9 provided to the upper end of the rod 8. Parts excepting activated carbon among materials coming into contact with water are made of a heat-resistant material such polymeric material or the like and activated carbon can be regenerated and sterilized by hot water of 80 deg.C or higher.

Description

DETAILED DESCRIPTION OF THE INVENTION

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tabletop water purifier (not connected to a water supply).

2. Description of the Related Art As a water purifier, a built-in water purifier incorporated upstream of a water tap, a stationary water purifier directly connected to the faucet, or a faucet-mounted water purifier is often used.
The desk-top type water purifier of the present invention is different from these, and is a system of purifying water after pumping water from a tap or the like into a container without being directly connected to a faucet. Tabletop water purifiers have been sold in large numbers both in Japan and overseas. As shown in FIG. 2, in each case, water 111 poured from the upper part 10 of the container is purified by passing through a cartridge 12 filled with a filtering material such as activated carbon and stored in a lower tank part 13. Is limited to the method that can be used. While these tabletop water purifiers have the advantage of being simple, the water flowing from the top,
There is a tendency that a passage that is easy to pass through (so-called Mizumichi) is formed, the chance of encountering impurities in the water and the filtering material is reduced, and the water purification capacity is reduced. In addition, the activated carbon cartridge must be replaced periodically with the life of the adsorptive capacity of the filter medium, or microorganisms such as bacteria and fungi will propagate in the filter medium layer and become unsanitary. There was.

FIG. 3 shows an embodiment of the present invention. The substantially cylindrical container 14 made of heat-resistant glass has an opening at the top for water in and out, and the opening is covered with a lid 15 having a hole 21 for a rod 22 to slide up and down. I have. At the lower end of the rod 22, an outer frame 18 of a heat-resistant glass piston filled with activated carbon 16 is attached while being pressed from above and below by a stainless steel fitting 19 together with a stainless steel net 17 holding the activated carbon 16. The stainless metal fitting 19 is provided with an appropriate hole through which water easily passes and which holds the net, and is fixed to the rod 22.
The upper end of the rod 22 is provided with a handle 23 for operating the rod up and down. When the rod is gently moved up and down, the water is purified by passing water through an activated carbon layer in a piston attached to the lower end of the rod. In addition, a pair of skirts 20 made of a soft heat-resistant polymer material are used to partition water above and below the piston around the outer periphery of the outer frame 18 of the piston in order to prevent water from flowing through a gap between the outer frame 18 and the inner wall of the container 14. Water was allowed to pass through only the activated carbon layer. In the present invention, since heat-resistant materials such as heat-resistant glass, stainless steel, and soft heat-resistant polymer material are used, activated carbon is regenerated by pumping hot water instead of water and moving the piston up and down to regenerate the original adsorption. Regain ability. In addition, since the unsanitary microorganisms that have begun to form in the activated carbon layer are sterilized by the passage of the hot water as described above, it is possible to always maintain a sanitary state without replacing the activated carbon.

As described above, the present invention realizes, for the first time, a simple desk-type water purifier capable of effectively and sanitarily purifying water for a long time without exchanging a cartridge such as an activated carbon of the table-type water purifier.
