The mounting portion 71 has a pair of guiding concave portions 73 for taking in the locking projection 42 of the mounting portion 41 along the direction of the central axis C1 of the clean water discharge port 4 and one rotation direction side from the lower portion of each guiding concave portion 73 And an engaging recess 74 formed to be continuous with the guiding recess 73. Then, by engaging the locking projection 42 with the engagement recess 74, the mounting portion 41 of the water purification outlet 4 and the connection joint 7 are mounted. As described above, in the present embodiment, the mounting portion 71 is formed so as to form a substantially L shape by the guiding recess 73 and the locking recess 74. In the present embodiment, the engagement recess 74 is formed as an opening communicating with the outside of the fitting portion 72.

Next, the procedure for attaching the connection joint 7 to the purified water discharge port 4 will be described.

First, the connection joint 7 is disposed at a predetermined rotational position with respect to the clean water discharge port 4 so that the locking projection 42 and the guiding recess 73 match in a bottom view. Then, by pushing the fitting portion 72 of the connection joint 7 into the mounting portion 41, the locking projection 42 is taken into the guiding recess 73 to be in the initial set position. In this embodiment, this initial set position is set to a position where the central axis C2 of the L-shaped tip of the connection joint 7 is substantially parallel to the central axis C3 of the water purification unit 6 (position A in FIG. 6) .

Then, by rotating the connection joint 7 in one direction indicated by the arrow α in FIG. 6 from the initial set position, the locking projection 42 is gradually engaged with the engagement recess 74 and rotated approximately 90 degrees. Mounting of the connection joint 7 is completed. At the mounting completion position (position B in FIG. 6) of the connection joint 7, the locking projection 42 abuts on the end of the engagement recess 74 and can not be further rotated.

On the other hand, when removing the connection joint 7, the reverse operation to the mounting is performed to rotate the connection joint 7 in the other direction from the B position to the A position, and the connection joint 7 at the A position is the clean water discharge port 4 It can be removed by pulling it out. When connecting joint 7 is rotated between position A and position B and attached or removed, connecting joint 7 does not interfere with casing 61 of water purification unit 6. That is, in the state where the hose 100 is not connected, the connection joint 7 is attached and detached (mounted and removed) to the attachment portion 41 of the water purification outlet 4 even when the water purification unit 6 is attached to the device body 11 It can be done.

Further, as shown in FIG. 4A, the tip end of the connection joint 7 which protrudes in an L shape from the fitting portion 72 is slightly tapered in order to fit the attachment end portion 100a of the hose 100. An insertion portion 75 is formed. Furthermore, on the base side of the insertion portion 75, an external thread portion 76 for screwing the fixing nut 101 of the hose 100 is provided. As described above, in the present embodiment, the connection joint 7 has a structure in which the hose 100 can be easily connected, and the water treatment device 1 can be easily connected to another water treatment apparatus via the hose 100. It can be done.

By the way, the rotation attachment / detachment structure between the water purification outlet 4 and the cover 8 is also the same as the rotation attachment / detachment structure between the water purification outlet 4 and the connection joint 7. That is, although not shown, the mounting portion provided on the inner peripheral portion of the cover 8 also has the same structure as the mounting portion 71 of the fitting portion 72 provided with the guiding recess 73 and the engaging recess 74. Then, the cover 8 can be attached and detached (mounted and removed) to the mounting portion 41 of the water purification outlet 4 with the connection joint 7 removed.

Further, as shown in FIG. 4, a circumferential groove 43 is formed at the tip of the mounting portion 41, and the seal ring S is fitted in the circumferential groove 43 as shown in FIG. 4. The seal ring S can seal between the water purification outlet 4 and the fitting portion 72 of the connection joint 7 or the cover 8 in a watertight manner. Therefore, in a state where the connection joint 7 is removed and the cover 8 is mounted on the mounting portion 41, dust and bacteria are prevented from adhering to the outer periphery of the water purification outlet 4, that is, the outer periphery of the mounting portion 41 including the seal ring S. It can be done.

By the way, in the present embodiment, an alkaline ionizer (electrolyzed water generator) 200 is used as another water treatment apparatus connected to the hose 100. As shown in FIG. 8, the alkaline ion water conditioner (electrolytic water generator) 200 connects the proximal end 100 a of the hose 100 to the distal end of the connection joint 7, and the alkaline ion water conditioning of the distal end 100 b of the hose 100. By connecting to the vessel 200, it is connected to the purified water discharge port 4 of the water treatment apparatus 1 via the hose 100. As this hose 100, it is preferable to use a flexible hose. The alkali ion water conditioner 200 can be installed at a place away from the water faucet F, for example, a sink or the like.

In the alkaline ion water conditioner 200, an electrolytic cell (not shown) is stored in the case main body 201. By introducing the purified water supplied from the hose 100 into the electrolytic cell, the purified water is electrolyzed to form alkaline ionized water. It is designed to produce acid water. Then, the alkaline ionized water is taken out from the discharge hose 202 provided in the upper part of the main body case 201 and used for drinking etc., and the acidic water is discharged from the drainage hose 203 provided in the lower part of the main body case 201 to a sink etc. ing. In addition, it is also possible to use for other purposes without discarding acidic water.

By the way, when the user rotates the faucet F on which the water treatment apparatus 1 is mounted with the connection joint 7 and the alkali ion water conditioner 200 connected via the hose 100, the hose 100, When rotating itself to the left and right, the connection joint 7 may be pulled by the hose 100 connected to the alkali ion water conditioner 200, and the connection joint 7 may rotate relative to the clean water discharge port 4. At this time, if the connection joint 7 is rotatable in the opposite direction (the other direction) to the rotational direction (one direction) when attached to the attachment portion 41, the connection joint 7 may be detached from the clean water discharge port 4 There is.

Therefore, it is preferable to arrange the water purification unit 6 so that the hose 100 and the water purification unit 6 interfere with each other when the connection joint 7 rotates in the other direction by a predetermined amount or more.

In the present embodiment, when the connection joint 7 attached to the attachment portion 41 of the clean water discharge port 4 is rotated in the other direction while the hose 100 is connected, the position of the connection joint 7 corresponds to that of the clean water discharge port 4. The water purifier unit 6 is disposed so that the hose 100 interferes with the water purifier unit 6 before the removable position from the mounting portion 41 (before the connection joint 7 becomes the A position in FIG. 6).

That is, as shown in FIG. 7, when the hose 100 is connected to the connection joint 7, the hose 100 and the water purification unit 6 interfere with each other when the connection joint 7 tries to rotate in the other direction by a predetermined amount or more. It was made to be in the positional relationship. The rotation more than the predetermined amount at this time is a rotation amount at which the connection joint 7 comes off from the clean water discharge port 4, and in this embodiment, is a rotation amount from the B position to the A position as shown in FIG. However, in practice, in order to prevent the connection joint 7 from coming off, it is necessary to secure a certain amount of engagement between the locking projection 42 and the engagement recess 74. Therefore, in the present embodiment, as shown in FIG. 7, the time when the hose 100 interferes with the water purification unit 6 is set to a rotation amount β (for example, approximately 35 degrees) smaller than 90 degrees between the B position and the C position. It is set.

As described above, when the connection joint 7 rotates from the B position to the C position, the fixing nut 101 of the hose 100 interferes with the water purification unit 6, whereby the connection joint 7 can not rotate in the other direction any more. It is possible to prevent the connection joint 7 from coming off the discharge port 4. The hose 100 may be made to interfere with the casing 61 of the water purification unit 6 at the K portion instead of the fixing nut 101 of the hose 100 (see FIG. 7).

Next, the operation of the water treatment apparatus 1 having such a configuration will be described.

First, when the faucet of the faucet F is opened, raw water is introduced into the apparatus main body 11 from the raw water inlet 2. At this time, either the discharge from the raw water discharge port 3 or the discharge from the clean water discharge port 4 is selected by the water channel switching lever 5, or the water channel switching lever 5 is operated so that either is selected. When it is switched, desired water can be taken out from the selected outlet. That is, raw water such as tap water or well water flowing out from the faucet F can be taken out from the raw water discharge port 3, and clean water filtered by the filtration cartridge 62 can be taken out from the water purification discharge port 4.

Then, when the connection fitting 7 is attached to the clean water discharge port 4 and the alkali ion water conditioner 200 is connected to the water treatment apparatus 1 via the hose 100 connected to the connection joint 7, the alkali ion water conditioner The alkaline ionized water can be taken out by 200.

Moreover, when the alkali ion water conditioner 200 is not used for a long time or when the alkali ion water conditioner 200 is not installed, the connection joint 7 is removed from the water purification outlet 4 and the water purification outlet 4 is covered. 8 will be worn.

As described above, in the present embodiment, the mounting portion 41 for detachably mounting the connection joint 7 to the clean water discharge port 4 is provided. And the water treatment apparatus 1 is mounted | worn with the connection joint 7 which is detachably mounted to the mounting part 41 provided in the clean water discharge outlet 4, and the connection joint 7 to which the hose 100 is detachably connected, and the said connection joint 7 removed. And a cover 8 detachably mounted so as to cover the portion 41.

Therefore, the purified water discharge port 4 can be easily connected to another water treatment apparatus (in the present embodiment, the alkaline ion water conditioner 200 as an electrolyzed water generating device) through the hose 100 connected to the connection joint 7 become. As a result, in addition to being able to switch and discharge the raw water and the purified water, it is possible to obtain the water treatment device 1 capable of easily supplying the purified water to other water treatment devices.

In addition, when it is not necessary to connect other water treatment devices, etc., the water purification outlet 4 can be returned to the original state by removing the connection joint 7 from the water purification outlet 4. At this time, in the present embodiment, since the cover 8 covering the mounting portion 41 is provided, the cover 8 can be mounted to the mounting portion 41 in a state where the connection joint 7 is removed. As described above, when the connection fitting 7 is not attached to the clean water discharge port 4 by attaching the cover 8 to the attachment part 41 and covering the attachment part 41 with the cover 8, the attached part 41 of the clean water discharge port 4 It is possible to suppress adhesion of dust and bacteria to the seal ring S. As a result, the clean water discharge port 4 can be prevented from becoming dirty, and the clean water discharge port 4 can be kept in a more hygienic state.

Further, in the present embodiment, with the mounting portion 41 of the clean water discharge port 4 as a rotation attachment / detachment structure, the fitted connection joint 7 is mounted by rotating in one direction about the clean water discharge port 4 and rotating in the other direction. It is supposed to be removed. On the other hand, when the hose 100 is connected to the connection joint 7, the positional relationship between the hose 100 and the water purification unit 6 interferes with each other when the connection joint 7 is rotated in the other direction by a predetermined amount or more. It has become.

That is, when the connection joint 7 attached to the attachment portion 41 of the clean water discharge port 4 is rotated in the other direction with the hose 100 connected, the position of the connection joint 7 is the attachment portion 41 of the clean water discharge port 4. The water purification unit 6 is disposed such that the hose 100 interferes with the water purification unit 6 before it becomes a detachable position (before the connection joint 7 becomes the A position in FIG. 6). As a result, even if the user pulls the hose 100 to rotate the connection joint 7 in the other direction, for example, when the user rotates the faucet to the left and right, the hose 100 interferes with the water purification unit 6 and the connection joint Further rotation of 7 is suppressed. Therefore, it can be suppressed that the connection joint 7 is detached from the mounting portion 41 of the water purification discharge port 4. For example, when using the water treatment apparatus 1 in a state in which the connection joint 7 and the alkali ion water conditioner 200 are connected via the hose 100, the connection joint 7 is the attachment portion 41 of the clean water discharge port 4. It is possible to prevent the generation of alkaline ionized water from becoming impossible.

Further, according to the present embodiment, the hose 100 connected to the connection joint 7 is connected to the alkali ion water conditioner (electrolytic water generator) 200. As a result, the purified water discharged from the purified water discharge port 4 can be electrolyzed by the alkali ion water conditioner 200 to generate alkali ion water. Thus, by connecting the hose 100 connected to the connection joint 7 to the alkaline ionizer (electrolyzed water generator) 200, not only raw water and purified water but also alkaline ionized water and acidic water can be generated. become able to.

In addition, when the alkaline ionized water is finally obtained from the purified water, the water treatment apparatus 1 that generates the purified water from the raw water only needs to have the filtration function, so the enlargement of the water treatment apparatus 1 is suppressed Thus, the water treatment apparatus 1 can be attached to the faucet F. On the other hand, since the alkali ion water conditioner 200 does not need to be equipped with a filtration function, it is possible to miniaturize the alkali ion water conditioner 200, and a user-friendly water treatment apparatus (water treatment apparatus 1 and alkali ion A water conditioner 200) can be obtained.
