Description

  The present invention relates to a water purifier, and more particularly to a built-in type, that is, a water purifier suitable for installing a cartridge under a sink of a sink.

In the conventional built-in type water purifier, when the storage part under the sink is installed in the drawer type sink, the cartridge is installed in the piping space part at the back of the drawer shelf (for example, see Patent Document 1).
In such a case, in order to replace the cartridge, it is necessary to remove the drawer shelf under the sink of the sink, and further replace the cartridge by inserting it under the sink. After removing the cartridge connection part in an unnatural posture There was a problem that a new cartridge had to be connected and a heavy old cartridge with water had to be taken out.

In order to solve such a problem, there is a cartridge in which a cartridge is disposed together with a water faucet on the upper edge of the back guard behind the sink (see, for example, Patent Document 2).
However, in this case as well, there is a problem in that it looks bad and a feeling of pressure arises because it is installed in the form of jumping out in front of the back guard.

JP 2003-213750 A (page 1-2, FIGS. 1 and 2) JP 2003-125870 A (page 1-2, first, second, third, sixth, 9a, FIG. 10)

  The present invention has been made to solve the above problems, and an object of the present invention is to improve the appearance of the sink by arranging the cartridge in an inconspicuous place, and without reducing the storage space of the sink, and the cartridge It is to be able to easily perform the exchange operation in an easy posture.

In order to achieve the above object, the invention described in claim 1 is a water purifier in which a cartridge for purifying tap water is stored in a storage portion under a sink of a sink, and the water purifier is a drawer shelf or The cartridge includes a fixing means for fixing the cartridge to the open / close door, and a piping means for supplying tap water to the cartridge and supplying purified water purified by the cartridge to the water discharging means. The cartridge is movable so as to follow the movement of the cartridge by moving back and forth, and the cartridge and the piping means are detachable.
For this reason, when the storage portion is opened, the cartridge can be pulled close to the hand and the cartridge replacement operation can be easily performed in an easy posture. Further, since the cartridge is stored in the space below the sink, the appearance can be improved and the pressure above the sink can be eliminated.

The invention according to claim 2 is configured such that the piping means is extendable or bendable, or has flexibility.
For this reason, when the hose part of the piping means is made of a hard material, it can be curled or stretched or bent in combination with a rotatable joint, and in the case of a soft material, it can be flexible. By providing this, it is possible to provide mobility and reduce the opening / closing operation force of the storage portion.

The invention according to claim 3 is configured such that the piping means has horizontal mobility.
For this reason, when the piping member moves in the vertical direction, when the storage part is opened and closed, the position energy fluctuates as much as the piping member and the joint move up and down, so the operating force when opening and closing fluctuates. There is no such inconvenience when expanding or contracting in the direction.

According to a fourth aspect of the present invention, a part of the piping means is fixed to a member formed integrally with the inner wall surface of the storage part or the storage part by the pipe fixing means.

Furthermore, the deformation of the piping material due to its own weight can be prevented and the operability of the drawer shelf can be improved.

According to a fifth aspect of the present invention, the pipe fixing means comprises a raw water channel side joint that communicates with the inlet side of the cartridge and a water purification channel side joint that communicates with the outlet side of the cartridge as separate bodies, and the distance between these axes is determined. The distance between the axes of the inlet side joint portion and the outlet side joint portion of the cartridge is the same.
For this reason, since a piping part bends in the shape of a parallelogram, piping can be made to move smoothly and reasonably at the time of storage operation of the drawer shelf.

According to a sixth aspect of the present invention, in the piping means, the raw water channel side joint and the water purification channel side joint are integrally rotated, and the inlet side joint portion and the outlet side joint portion of the cartridge are also integrated. It was comprised so that it might rotate.
For this reason, since the pipe joint portion rotates integrally, the pipe can be moved more smoothly and effortlessly than the structure shown in claim 5 when the storage portion is opened and closed.

According to a seventh aspect of the present invention, in the piping means, the raw water channel side joint, the water purification channel side joint, the inlet side joint portion and the outlet side joint portion of the cartridge have a spherical joint structure.

Thus, by making it bendable in combination with a rotatable joint, it is possible to provide mobility and reduce the opening / closing operation force of the storage portion.

3 and 4 show side views of the first embodiment of the present invention.
FIG. 3 shows a state in which the cartridge 10 is installed on the back surface 14a of the lower drawer shelf 14 of the drawer type sink 1, and the lower drawer shelf 14 is stored.
FIG. 4 shows a state in which the lower drawer shelf 14 is pulled out in FIG.
As shown in FIG. 3, the cartridge 10 is fixed by a cartridge fixing bracket 18 so as to be disposed in the dead space 19 above the piping space 15 behind the back surface 14 a of the lower drawer shelf 14.
For this reason, it is possible to effectively utilize the piping space, which is the dead space behind the drawer shelf under the sink, without reducing the storage space of the drawer shelf. Further, the fixture 5 is fixed to the back plate 101 of the sink 1 with wood screws. The piping means is disposed so as not to interfere with the sink 102, the trap 103, the drain pipe 104, and the upper drawer shelf 105, and is configured to move in the gap between the drawer shelf 14 and the upper drawer shelf 105.
Therefore, when the storage portion is opened and closed, the piping means does not interfere with the members in the sink, so that the operability is not deteriorated and the flow rate is not reduced due to the constriction.

As shown in FIG. 4, the universal joint 6, the raw water hose part 7, the intermediate universal joint 8, the raw water hose part 9, the coaxial joint 11 of the cartridge 10, the purified water hose part 12, and the purified water hose part 13 are the drawer shelves 14. It is configured to move horizontally as it is opened and closed.
As a result, when the piping member is moved in the vertical direction, when the storage part is opened and closed, the positional energy changes by the amount that the piping member and the joint move up and down, so the operating force when opening and closing varies. In the present invention, there is no such inconvenience because it is bent in the horizontal direction.

FIG. 5 is a cross-sectional view of the joint portions 6, 8, and 11 of the piping means. The joint portions 6, 8, and 11 are all coaxial, and raw water and purified water are divided by a case 61, an inner cylinder 62, a connection member 63, a clip 64, and O-rings 65, 66, 67, and 68. Note that the case 61 is used in common for the upper and lower sides, and the universal joint 6 attached to the fixing bracket 5 and the intermediate universal joint 8 are also used in common.
The coaxial joint 11 connected to the cartridge 10 is connected to the raw water by the connecting portion 74i formed in the upper case 74 of the cartridge 10, the inner cylinder 72, the seal portion 73c of the lower case 73 of the cartridge 10, and the O-rings 75, 76, 77. Water purification is divided.
The raw water is composed of a raw water hose part 9, a raw water inlet 11e of the universal joint 11 to a raw water channel 11a inside the raw water inlet 11e of the universal joint 11, a seal part 73c, an activated carbon part 10d which is a filter medium in the cartridge 10, and a hollow fiber membrane part 10e. After being purified by way of the water, it passes through the water purification passage 11b outside the inner cylinder 72 and the water purification outlet 11f to reach the water purification hose portion 12.
In the piping means between the cartridge 10 and the raw water channel 4b and the water purification channel 4c of the water purifier faucet 4 described above, the coaxial joint 11 can be attached and detached for the purpose of replacing the cartridge 10.

FIG. 6 is a perspective view showing the attachment / detachment structure of the cartridge 10 and the piping means.
In FIG. 6, the cartridge 10 has a claw 10a for preventing the coaxial rotary joint 11 from falling off and is fitted with a flange 11c of the coaxial rotary joint 11, and notches 10b and 11d are formed on both sides. The drawer shelf 14 is arranged so that it can be attached and detached at a position where it does not fall off when the drawer shelf 14 is opened and closed.
Accordingly, the coaxial rotary joint 11 does not fall off during a normal drawer shelf opening / closing operation, and when the cartridge 10 is replaced, the flange portion 11c of the coaxial rotary joint 11 is rotated to a position facing the notch 10b of the cartridge 10. It can be attached and detached.
The raw water hose portion 7 and the purified water hose portion 13 on the side of the universal joint 6 are held by the hose holding portion 16a of the pipe support means 16, and supported by the fulcrum portion 5b of the fixing bracket 5 at the other end 16c of the arm 16b.
The raw water hose portion 9 and the purified water hose portion 12 on the cartridge 10 side are held by the hose holding portion 17a of the pipe support means 17, and are supported by the fulcrum portion 10c of the cartridge 10 at the other end 16c of the arm 17b.
For this reason, since piping support means 16 and 17 rotate mutually mutually, piping means bends horizontally (refer to Drawing 2 and Drawing 5).

FIG. 7A is a detailed view of the hose holding portion 16a of the pipe support means 16 in FIGS. 2 and 5 as viewed from the cross-sectional direction of the hose, and the raw water hose portion 7 and the purified water hose portion 13 on the universal joint 6 side are pipes. It is held at the hose holding portion 16a of the support means 16.
Similarly, the pipe support means 17 is supported by the fulcrum portion 10c of the cartridge at the other end 17c of the arm 17b.
For this reason, the piping means bends horizontally to prevent deformation of the piping material due to its own weight and improve the operability of the drawer shelf 14.

As described above, the piping means is configured to bend in the horizontal direction in the gap with the drawer shelf 105 above the drawer shelf 14, and when the drawer shelf 14 is pulled out, the cartridge 10 is pulled out to the vicinity of the drawer opening. Therefore, when the cartridge fixing bracket 18 is released and the storage portion is opened, the cartridge can be pulled close to the hand and the cartridge can be easily exchanged in an easy posture.
Further, since the cartridge is stored in the space below the sink, the appearance can be improved and the pressure above the sink can be eliminated.

FIG. 8 shows a second embodiment in which the joint portion of the piping means is changed from coaxial to biaxial in FIG. 5 of the first embodiment.
Note that “′” is added to the end of the code, or 3 to 4 digits are added to correspond to the first embodiment. Since the structure is the same as that of the first embodiment, the description is omitted.
In the second embodiment, the hose 7 ', 9', 12 ', 13' further follows the deflection due to its own weight, so that the hose 7 ', 9', 12 ', 13' is not bent at the connecting portion. 11a ′ and the purified water passage 11b ′ were used as a spherical joint 81. The spherical joint 81 has a spherical packing 82 in contact with the spherical surface portion 81 a and is sealed with a ring 83 and a nut 84 for preventing detachment. In this embodiment, both the raw water side and purified water side spherical joints have the same structure.
For this reason, even if the pipe joint part on the water purifier faucet side and the pipe joint part on the cartridge side are not positioned horizontally, or even if the hose part is bent due to its own weight, the hose will not be bent at the joint with the joint. .
Further, the axial distances Pa and Pb between the raw water side joints 601 and 801 and the purified water side joints 602 and 802 are made the same as the axial distance Pc between the raw water side joint part 1101 and the purified water side joint part 1102 of the cartridge 10. In the piping means, the joint portion and the hose portion can be deformed without difficulty into a parallelogram in accordance with the opening / closing operation of the storage portion, and the same function as the coaxial joint can be exhibited.

FIG. 7B is a detailed view of the hose holding portion 16a ′ of the pipe support means 16 ′ in FIG. 8 as viewed from the cross-sectional direction of the hose, the raw water hose portion 7 ′ on the universal joint 601 side, and the purified water hose portion 13 ′. Is held in the hose holding portion 16a ′ of the pipe support means 16 ′.
Similarly, the pipe support means 17 ′ (not shown) is supported by the fulcrum portion 10c ′ of the cartridge at the other end 17c ′ of the arm 17b ′. For this reason, the piping means bends horizontally.
Therefore, as in the first embodiment, the pipe material can be prevented from being deformed by its own weight, and the operability of the drawer shelf can be improved. Since the positional energy varies as the member or joint moves up and down, the operating force when opening and closing varies, but there is no such inconvenience because it bends in the horizontal direction.

9 and 10 are top views showing the third embodiment.
FIG. 9 shows a state in which the cartridge 10 is installed on the back surface 14a of the lower drawer shelf 14 of the drawer type sink 1, and the lower drawer shelf 14 is stored.
FIG. 10 shows a state in which the lower drawer shelf is pulled out in FIG.
In the third embodiment, only the joint portion 11 of the cartridge 10 is left out of the piping means of the first embodiment, the remaining joints are eliminated, and the flexible hose 33, 34 and the pulley 35 that supports the hose are provided. The support means 37 is used.
A portion corresponding to the fixing means 5 in the first embodiment is shown as a top view in FIG. 11 and as a front view in FIG. The hose guide 32 having two shafts in a twisted position is formed, and the raw water hose 33 and the purified water hose 34 are fixed by being sandwiched between the hose fixing brackets 31.
For this reason, when the storage portion is opened and closed, the piping means does not interfere with the members in the sink, so that the operability is not deteriorated and the flow rate is not reduced due to the constriction.

The portion corresponding to the intermediate joint 8 is composed of a pulley 35 and flexible hoses 33 and 34 as a pipe support means, as shown in FIGS. Can do.
Therefore, since the hose is smoothly bent along the groove of the pulley without breaking, the flow area does not decrease and the flow rate does not decrease.
Moreover, by giving flexibility with a soft material, it can be provided with mobility and the opening / closing operation force of the storage portion can be reduced.
Furthermore, since the piping means can be moved horizontally, when the piping member is moved in the vertical direction, when the storage part is opened and closed, the position energy fluctuates as much as the piping member and the joint move up and down. The operating force for closing varies, but there is no such inconvenience when bending in the horizontal direction.
As the drawer shelf 14 is pulled out, the ratio between the hose length on the water purifier faucet 4 side of the pulley 35 and the hose length on the cartridge 10 side slightly fluctuates, but this pulley mechanism applies an excessive external force to the hose. There is no.
Since the guide roller 36 is provided on the pulley 35, the hose 33, 34 does not come off the pulley 35 even if the hose 33, 34 sags.
The method for replacing the cartridge 10 is the same as in the first and second embodiments.

In the present invention, since it is configured as described above, it is possible to easily perform the cartridge replacement operation in an easy posture by pulling the cartridge to the hand when the storage portion is opened. Further, since the cartridge is stored in the space below the sink, the appearance can be improved and the pressure above the sink can be eliminated.
In addition, the piping space, which is a dead space behind the drawer shelf under the sink, can be effectively used, so that the storage space of the drawer shelf can be saved. Furthermore, in this third embodiment, the cost can be reduced by reducing the number of joints, and when the pipe is replaced for breeding in the general bacteria pipe from the water outlet of the water purifier faucet, only the hose is replaced. It is economical.
In the present embodiment, the drawer-type sink has been described, but it goes without saying that the same effect can be obtained even if the present invention is applied to a door-type sink.
