Description

Detailed Description of the Invention [Industrial applications]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water purifying device which can convert unpurified water into drinking water by filtering, and to a cartridge filter in this water purifying device.

[Prior Art]

In conventional water purifiers for general households, a water supply pipe provided in the water purifier is connected to the base of the faucet with a screw, so that when the cock is opened, unclean water is purified by the filter medium provided in the water purifier. The water is drained from the drain pipe (see Fig. 3). Although a filter paper, a net, cotton, etc. were often used as a filter medium provided in the water purifier, there is a filter using activated carbon in order to remove bacteria, odor, taste, etc. to make delicious drinking water.

There is also a magnetic filter which is made to adsorb to a magnet in order to remove iron, nickel and the like mixed in unclean water. There is a theory that magnetism activates water in addition to removing iron mixed in unclean water. In other words, when the magnetic lines of force act on a substance or molecule dissolved in water, the molecular structure of water changes, and due to the synergistic effect with the kinetic energy of water, the mutual relationship of electrons is disrupted and the water molecule becomes smaller. It is said to do so. As a similar theory, it is said that when far infrared rays are given to water, the molecular structure of the water changes and the water becomes delicious.

Some water purifiers have been provided with activated carbon and magnets in an attempt to make drinking water more delicious by using activated carbon and magnets. For example, in this type of water purifier (see cutaway side view in FIG. 3), a magnet M is provided at an intermediate portion of a discharge pipe P1 provided in the water purifier main body A, and a filtering material B for filtering unpurified water is provided in the water purifier main body. Since it is provided in A, unpurified water can be sent to the discharge pipe P1 from below as passing unpurified water through the filter medium B as shown by the arrow. Therefore, unpurified water enters from the water supply port 10 and the filter B
When the purified water filtered in step 1 flows into the drainage pipe P1, the magnet M provided in the drainage pipe P1 removes minute iron in the purified water and magnetizes the purified water into magnetized water.

[Problems to be Solved by the Invention]

As described above, in the water purifier using the activated carbon and the magnet, if the magnet is provided in the middle portion of the discharge pipe provided in the main body of the water purifier, the flow velocity of the purified water passing through the filter medium to the discharge pipe is increased. However, since the flow velocity is rapid, there is a disadvantage that it is not possible to remove iron and to turn the water into magnetized water unless a large number of magnets are provided to magnetize the purified water.

Further, if it is provided in the middle portion of the discharge pipe, there are disadvantages that the assembly of the magnet and the cutting work of the discharge pipe are troublesome, the cost becomes high, and the length of the discharge pipe becomes long.

In order to eliminate such drawbacks, an object of the present invention is to incorporate activated carbon and a magnet into a cartridge filter body,
In addition, in the state where the flow velocity of the purified water is suppressed in the purified water passage, the purified water is allowed to come into good contact with the magnetic force of the magnetic member.

[0008]

An outer peripheral side wall is a filter wall layer for filtering unpurified water, and a water purification channel formed by this filter wall layer and formed in the longitudinal direction, and an upper part of this filter wall layer. And an upper cover fitted with a hole formed at the clean water outlet of the water purification channel, a lower cover fitted to the lower part of the water purification channel to close the water purification channel, and a water purification layer formed of a filtration wall layer. With the magnetic member in the passage, unclean water passes through the filter wall layer from the outer peripheral side wall, and the flow velocity of the purified water is suppressed in the water purification passage, so this purified water is generated in the water purification passage formed by the filtration wall layer. It is to be able to sufficiently apply to the magnetic member.

[Action]

Unclean water passes through the filter wall layer from the outer side wall,
When the flow velocity of the purified water is suppressed in the water purification passage, the iron component is filtered by the magnetic member in the water purification passage formed by the filtration wall layer of the purified water.

FIG. 1 is a perspective view showing the inside by cutting out a part of the filter B. FIG. 2 is an exploded perspective view showing a main part by cutting out a part of the water purification apparatus main body A showing the main part.

In FIG. 1, reference numeral 1 is a filter wall layer for filtering unpurified water, and a filter paper 3 is provided on an outer peripheral side wall surface 2 of the filter wall layer 1.
Is formed so as to be covered with the net 4. Moreover, the water purification channel 5 formed in the vertical axis direction of the filter wall layer 1 is formed. The upper cover 7 having the hole 6 located at the purified water outlet 5 ′ of the purified water passage 5 is fitted to the upper portion 1 ′ of the filtration wall layer 1. At this time, the purified water outlet 5 ′ of the purified water passage 5 is located in the hole 6 of the upper cover 7. Further, a lower cover 8 for closing the lower portion 5 ″ of the water purification passage 5 is fitted.

The unclean water from the side wall 9 "of the upper cap 9 and the filter B
It penetrates into the filter wall layer 1 while entering the space. Therefore, the unpurified water passes through the filter wall layer 1 as shown by the arrow to become purified water and flows into the water purification passage 5, and the flow velocity is suppressed, so that a minute iron component can be adsorbed by the magnetic member M ′ and made into magnetized water. 12 is a lower cap that fits under the upper cap 9, and 13 is an upper edge 12 ′ of the lower cap 12.
