The mainstream is a structure in which one water purification cartridge is arranged in the main body container. For example, when a water purifier is required to have a function of dechlorination and a function of removing various germs and red rust, one water purification cartridge is required. It is necessary to dispose an adsorbent such as activated carbon and a filter material such as a hollow fiber membrane therein. For this reason, the amount of the purifying material per type of purifying material is reduced, so that both the adsorbing ability and the filtering ability are insufficient, and the purifying ability is naturally limited.

Grooves 11 are formed along the circumference on the outer periphery of the treated water inlet 8 and the treated water outlet 10.

As shown in FIG. 2, the stationary base 5 has a concave fitting portion 12 into which the water purification cartridge 4 is removably fitted, and an external introduction for introducing water to be treated into the stationary base 5 from outside. An outlet 13, which communicates with the external inlet 13 through an inlet channel 14, and which is connected to the water inlet 8 of the water purification cartridge 4 at the fitting portion 12; A treated water inlet 16 connected to the treated water outlet 10 of the water purification cartridge 4, and an external outlet that communicates with the treated water inlet 16 through a discharge passage 17 and discharges treated water from inside the stationary base 5 to the outside. 18 is a rectangular parallelepiped base on which is formed.

In the stationary base 5, the external inlet 13
The external discharge port 18 is coaxial with the external discharge port 18 of the stationary base 5 and the external introduction port of the other stationary base when the stationary base of another stationary water purifier of the same type is connected adjacently. They are formed coaxially so that they are connected to each other. The joint 6 is a tubular connecting member, and as shown in FIG. 3, three ridges 19, 20, and 21 each having a trapezoidal cross section along the circumference, and sandwiched between the ridges and along the circumference. Two grooves 22 and 23 are formed.

In this embodiment, a method using a one-touch joint is adopted as an example of a method of attaching and detaching the water purification cartridge 4 to and from the stationary base 5 and an example of a method of attaching and detaching the stationary base 5 to and from the joint 6. As an example of this attaching / detaching method, a case where the treated water inlet 8 (connection portion) of the water purification cartridge 4 is attached to / detached from the treated liquid outlet 15 (connection portion) of the stationary base 5 will be described with reference to FIG. The one-touch joint is configured to be able to swing in a direction orthogonal to the circumferential direction so that the water inlet 8 can be treated.

Only the installation space corresponding to the stationary bases 5 corresponding to the number of the bases 4 is required. That is, when the water purification cartridge 4 is not added, no useless space is required and the space is saved. Further, the stationary base 5 is discharged from the treated water discharge port 10 of the water purification cartridge 4, and the processing liquid flowing from the treated water inlet 16 of the stationary base 5 to the external discharge port 18 through the discharge flow path 17 is separated from the other. It can be supplied to the water purification cartridge of the stationary water purifier of the same type. Therefore, when the stationary bases 5 are connected adjacent to each other, a flow path is formed inside the stationary base, so that it is not necessary to use a separate connection pipe, and the installation space can be further reduced in size.

(Embodiment 2) Next, an embodiment in which a plurality of stationary water purifiers 1 are connected will be described. FIG. 5 shows a first embodiment.
It is a figure which shows the stationary water purifier 50 of the form which connected two stationary water purifiers 1 of FIG.

Grooves 33 are formed along the circumference at the distal end of the treated water pipe 31 and at the outer periphery of the base end of the discharge pipe 32. As for the attachment / detachment method, a method using a one-touch joint is employed in the same manner as in the case of attaching / detaching the treated water inlet 8 of the water purification cartridge 4 to / from the treated liquid outlet 15 of the stationary base 5. Then, the water pipe 31 can be attached to and detached from the stationary base 5 by the engagement of the grooves 33 of the water pipe 31 with the plurality of balls 24 provided at the external inlet 13 of the stationary base 5 on the upstream side. The discharge pipe 32 is fixed to the stationary base 5 by engaging the grooves 33 of the discharge pipe 32 with the plurality of balls 24 provided at the external discharge port of the stationary base 5 on the downstream side. Removably locked.

Purification of the water to be treated using the stationary water purifier 50 is performed as follows. The to-be-processed water that has flowed into the to-be-processed water pipe 31 from the tap of the tap water by the switching valve is introduced from the external introduction port 13 to the stationary base 5 on the upstream side, passes through the introduction flow path 14 and to the to-be-treated water discharge port 15 The water is supplied to the water purification cartridge 60 from the treated water inlet 8 of the water purification cartridge 4 to be connected.

The water to be treated, which is supplied to the water purification cartridge 60 and spreads around the ion exchange resin (1) 61 through the water passage 7 to be treated, passes through the hollow fiber membrane 27 from the ion exchange resin (2) 62. It is treated in between and becomes treated water. The treated water that has passed through the sintering filter 63 passes through the treated water inlet 16 of the stationary base 5 connected to the treated water outlet 10 of the water purification cartridge 60, passes through the discharge channel 17, and passes through the external outlet 1

The treated water introduced into the stationary base 5 on the downstream side passes through the introduction flow path 14 and is connected to the treated water discharge port 15 through the treated water introduction port 8 of the purified water cartridge 4 on the downstream side. Supplied to The adsorbent 3 is supplied to the water purification cartridge 4 on the downstream side and passes through the water passage 7 to be treated.
Of the treated water that has spread around the hollow fiber membrane 2 from the adsorbent 3
During the passage through 7, the water is reprocessed into reprocessed water. The retreated water is sent from the treated water inlet 16 of the stationary base 5 connected to the treated water outlet 10 of the water purification cartridge 4 to the discharge pipe 32 connected to the external outlet 18 through the discharge passage 17,
It is discharged from the tip of the discharge pipe 32.

In such a stationary water purifier 50,

Residual chlorine, mold odor (2 MIB, diosmin), trihalomethane, pesticides, organic solvents, A colloidal heavy metal, a soluble heavy metal, nitric acid / nitrite nitrogen, etc. may be appropriately selected depending on the object to be removed and the purpose. In addition, when a hollow fiber membrane is used, it is preferable to dispose it in the water purification cartridge that is the most downstream, because it is possible to prevent reverse contamination of the filtration material due to invasion of bacteria from the water purification outlet. In that case, if the water purification cartridge connected to the upstream of the water purification cartridge provided with the hollow fiber membrane is not provided with the hollow fiber membrane and only the adsorbent is used, the pressure loss can be reduced and the volume of the adsorbent can be increased. Becomes possible,
It is more preferable because the processing capacity can be improved.

Further, in such a stationary water purifier 50, since the stationary base 5 can be increased or decreased according to the number of water purification cartridges, it corresponds to the stationary base 5 corresponding to the number of water purification cartridges. In other words, when only an additional water purification cartridge is required, no extra space is required, and space is saved. The stationary base 5 is discharged from the treated water discharge port 10 of the water purification cartridge 60, and the processing liquid flowing from the treated water inlet 16 of the stationary base 5 to the external discharge port 18 through the discharge flow path 17 is transferred to the downstream side. The water can be supplied to the water purification cartridge 4 from the water introduction port 8 of the water purification cartridge 4 on the downstream side connected to the water discharge port 15 from the external introduction port 13 of the stationary base 5 through the introduction flow path 14. ing. for that reason,
Since the stationary bases 5 are connected adjacently without using a separate connection pipe, the installation space can be further reduced.

The stationary water purifier 50 in the illustrated example has a water purifying cartridge 60 and a water purifying cartridge 4 each having a total of 2 units.
Although the number of the base and the stationary base 5 are two, the stationary type water purifier of the present invention is not limited to this, and may be expanded to three or more in accordance with the required water purification capacity.

It doesn't matter.

For example, the external discharge port 18 is provided on each side of the stationary base 5 other than the side on which the external inlet 13 is formed.
By forming a total of three each, the connection direction between the stationary bases 5 can be freely changed. Thereby, as shown in FIG. 6, the four stationary bases 5 can be arranged so that each of them is adjacent to each other on two sides, and the installation space can be further reduced. . Further, the direction in which the water to be treated is introduced into the stationary water purifier can be the same as the direction in which the treated water is discharged from the stationary water purifier. And / or the length of the discharge pipe 32 can be shortened. The unused external outlets 18 are preferably sealed with plugs 34, 34, respectively.
