Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water purifier for domestic use, which is used by being connected to a faucet for water supply.

[0002]

2. Description of the Related Art A large number of various water purifiers for home use have been proposed. The water purifying system uses activated carbon, an ultrafiltration membrane such as a hollow fiber membrane, or Is
There are various combinations of these. However, in any of the water purifiers, the water purification material is contained in one cartridge that is detachable from the apparatus main body, and when the service life has passed, the cartridge is replaced. Also,
The installation method is a type in which the water intake of the water purifier is connected to a water faucet via a switching cock, and purified water is supplied from a separate faucet attached to the water purifier.

[0003]

However, in the conventional water purifier, even if a plurality of water purifying materials are used together, as described above, there is only one cartridge, and a plurality of water purifying materials are accommodated in the same cartridge. There is. However, since the service life of the purified water material is usually different for each material, the entire service life is determined according to the short service life, and there is waste in using the material.

Further, in the conventional water purifier, since the raw water is supplied from the position of the tap, and the purified water is supplied from the faucet of the water purifier, there are two faucets, which is inconvenient to use. . However, it is also proposed that the switching cock is built into the water purifier so that both water flows out from the faucet of the water purifier, but with this method, the normal water faucet becomes a complete obstacle. I will end up. Water faucets such as kitchens
It is convenient and very costly not to use the faucet because it is usually designed and placed in the most convenient position.

The present invention is intended to provide a water purifier that solves the above-mentioned drawbacks, is highly convenient, is easy to handle and is economical.

[0006]

The technical means of the water purifier of the present invention comprises a water purifier main body and a plurality of cartridges containing different water purifying materials, and the water purifier main body has a water passage connecting seat. , The cartridge has a water passage joint, the water passage joint of the water purifier body and the water passage joint of the cartridge can be freely attached and detached, and raw water passes through the cartridge in series to purify different water. It is to receive the action sequentially.

The cartridge may be made of a transparent material so that the state of the water purifying material inside can be seen through from the outside.

Further, the number of cartridges is two, and water passage connecting portions are provided at the lower end and the side surface of each cartridge. On the other hand, the water purifier body has two sets of lower end water passage connecting seats and side water passage connecting seats. It is also possible to provide the lower water passage connecting seats so that the lower water passage connecting seats are movable and the side water connecting seats communicate with each other.

Further, a switching cock is attached to the water supply faucet to connect the switching cock and the water purifier body with a flexible water distribution pipe, and the water distribution pipe has two water paths for reciprocating, and after water purification. It is also possible to return to the switching cock again and supply water from the position of the cock.

[0010]

In the water purifier of the present invention, the number of cartridges is plural, and the water purifying materials of different kinds are contained in each of them.
Further, the cartridges are individually attachable to and detachable from the water purifier body. Therefore, each cartridge can be replaced. Raw water passes through each cartridge in series and is subjected to different purification actions and purified.

When the cartridge is made of a transparent material, the inside of the water can be seen through, so that the state of deterioration of the water purification material can be known. For example, in an ultrafiltration membrane such as a hollow fiber membrane, stains are attached and discolored with use, so that the deterioration state can be seen at a glance. Therefore, the replacement of the cartridge can be performed in a timely manner, and the water purification material can be used to the maximum extent to the maximum service life.

In a case where two cartridges are used and water is connected at the lower end and the side surface, water first enters one of the cartridges from the lower end water connecting portion and passes up and down through the cartridge. It receives a water purification action in the meantime and flows out from the side water passage joint. Then, after passing through the side water passage connecting seat of the main body, it enters the other cartridge from the side water passage connecting portion, receives another water purification action while descending and passing through the cartridge, and flows out from the lower end water passage connecting portion. To do. Since the lower end water passage connecting seat of the container body is movable, the loading of the cartridge is performed by first fitting the lower end water passage connecting part of the cartridge into the lower end water passage connecting seat of the container body, and then inserting the cartridge into the lower end water passage. If the connecting seats are pushed sideways, the side water passage connecting portion of the cartridge and the side water passage connecting seat of the main body are fitted together. To remove the cartridge, reverse the procedure.

In the case of adopting the return system to the switching cock, when the switching cock is set to "clean water", the raw water discharged from the faucet is sent from the switching cock to the water purifier through the distribution pipe for the outgoing path, After receiving the water purification action in, the water returns from the outlet of the switching cock to the switching cock again through the distribution pipe for the return path. When the switching cock is set to "raw water", the raw water discharged from the faucet passes through the switching cock as it is and is supplied from the outlet of the cock without being sent to the water purifier. Therefore, in this system, both in the case of raw water and the case of purified water, water is supplied from the outlet of the switching cock. Further, in this system, since a flexible water distribution pipe is used, the installation position of the container body can be freely selected.

The shape of 27 is the same. The outer cases 27, 27 are made of transparent synthetic resin and have an assembled structure in which upper and lower divided bodies are joined. One of the cartridges 2 is filled with granular activated carbon 28. A water-permeable sheet 2 such as a non-woven fabric is formed on the inner surfaces of the water-permeable coupling portions 13 and 18 in order to prevent activated carbon from coming out.
9 is attached. The hollow fiber membrane 30 is housed in the other cartridge 3 in a state of being packed in the inner case 31.

As described above, the two cartridges 2, 3
Therefore, the raw water that has been sent first enters the one cartridge 2 from the lower end water-passage coupling portion 13, and while moving upward in the cartridge 2, the raw water is subjected to the purifying action of the activated carbon 28 and side water passage. It flows out from the connecting portion 18. And
This water immediately enters the other cartridge 3 from the side surface water-passing joint portion 19 and, while flowing down from the top to the bottom in the inner case 31, is subjected to the water purifying action of the hollow fiber membrane 30 and from the lower end water-passing joint portion 14. leak.

Therefore, the raw water consists of two cartridges 2, 3
During the sequential passage through the water, the activated carbon 28 and the hollow fiber membrane 30 are subjected to a purifying action, and residual chlorine, various metal ions, polymer pollutants, etc. contained in the raw water are removed to obtain clean water. In addition, since water flows to another cartridge through the side water passage connecting portions 18 and 19, the flow passage is shorter than the method in which water passage is connected only at the lower end, and as a result, the water pressure decreases with the passage of the water purifier. With less water consumption, it is possible to prevent a decrease in the water supply when using purified water.

FIG. 4 shows the back surface of the mounting portion of the lower water passage coupling seat 11. The board 10 is provided with a long hole 32, and the foot portion 33 of the coupling seat 11 is fitted into the long hole 32, and the foot portion 33 is movable within the range of the long hole 32.

The detailed structure of the switching cock 4 is shown in FIG. A cock body 41 is rotatably mounted on the cock body 40, and the cock body 41 is rotatable by a handle lever 42. 43 is a raw water inflow hole, 44 is a raw water outflow hole to the water purifier, 45 is a purified water inflow hole from the water purifier,
46 is a purified water passage, 47 is a purified water outflow hole, 48 is a raw water outflow hole, 49 is a raw water outflow hole for shower, 50 is a raw water / purified water straight outlet with a wire mesh, 51 is a raw water shower outlet having pores, 52 is packing, 53 is a faucet retainer, and 54 is a cap nut for fixing.

The switching cock 4 can be switched to three directions of "raw water", "raw water shower" and "purified water". When the switching position is set to “clean water”, the raw water from the faucet 5 enters the cock body 41 through the inflow hole 43, and flows from the open outflow hole 44 to the water purifier through the water distribution pipe 6 (for the outward path). Sent. Then, the purified water discharged from the water purifier returns to the switching cock 4 through the water distribution pipe 7 (for the return path), and the purified water outflow hole 45,
Water is supplied from the straight outlet 50 through the purified water passage 46 and the purified water outlet 47.

When the switching cock 4 is set to the "raw water" position, the outflow hole 44 of the cock body 41 is closed and the raw water outflow hole 48 is opened, so that the raw water from the faucet 5 is directly switched without going to the water purifier. After passing through the cock, water is supplied from the straight outlet 50. Further, when set to the position of "raw water shower", the raw water outflow hole 49 for shower is opened, so that the raw water is supplied from the raw water shower outlet 51 in a sprinkling state.
