DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water purifier provided with a water purification material such as activated carbon or hollow fiber membrane, and for purifying raw water with the water purification material.

[0002]

2. Description of the Related Art Recently, hot water mixer taps have become widespread at home, and the number of cases in which a water purifier is attached to this faucet is increasing. However, water purifiers equipped with water purification materials such as activated carbon,
The surface of the activated carbon is coated with an antibacterial material such as silver in order to prevent the propagation of various bacteria. If hot water is continuously sent from the faucet, the antibacterial material coated on the activated carbon may be eluted. When a filter material such as a hollow fiber membrane is used, the filter material may be deteriorated by heat and lose the filtering effect. Therefore, conventionally, a valve mechanism comprising a shape memory spring material and a valve piece is disposed in the middle of the water passage from the faucet to the water purification material, and when hot water having a predetermined temperature or more flows in, the shape memory spring material is deformed to the water purification material. Water purifiers that prevent the inflow of hot water have been proposed. (JP-A-2-9488)

[0003]

However, in the above-mentioned water purifier, a cock for switching between raw water and purified water, a lever for driving the cock, and a shape memory alloy are provided in a direction orthogonal to the flowing direction of the raw water flowing from the faucet. A hot water inflow prevention valve mechanism comprising a spring material and a valve piece is provided, and the direction of deformation of the shape memory spring material constituting the valve mechanism, that is, the longitudinal direction of the valve mechanism is orthogonal to the flow direction of raw water flowing from the faucet. Since it is formed so as to be oriented in the same direction, the shape of the main body composed of the cock, the lever, and the valve mechanism is widened, and the compactness is imposed. In particular, in the type in which the water purification section is connected to the side of the main body at the position where the water passage of the valve mechanism is extended, a strong horizontal impression is given to give a sense of oppression.

[0004]

SUMMARY OF THE INVENTION Therefore, the present invention is directed to a raw water straight mode in which raw water having a mounting portion 5 detachably mounted on a raw water faucet 4 is provided in a raw water straight mode in which raw water flows directly below the main body 1. A cock unit 10 for switching to a water purification mode in which raw water passes through the water purification materials 23, 24, and 33 to purify water.
And a lever 7 for driving the cock portion 10. The cock portion 10 changes the flow of raw water flowing from the faucet 4 in a water purification mode to an orthogonal direction, and has a rotary cock having the same direction as a rotation axis. Body 12 and the cock body 12
And a cock tube 11 for accommodating the cock body 12.
The lever 7 is provided at one end of the rotation shaft of the cock, and the water purification materials 23, 24, 33 are provided at the other end of the rotation shaft of the cock body 12.
Material 29 that is deformed by a change in water temperature for blocking water flow to the side, a valve piece 26 that is resiliently resilient due to the spring force of the spring material 29, and a housing for accommodating these and a rotating shaft of the cock body 12. And a casing 41 that forms a water passage in a direction perpendicular to the flow of the raw water flowing from the faucet 4 and a direction perpendicular to the flow of the raw water flowing from the faucet 4. By matching the directions of the formed water passages, the longitudinal axis of the valve mechanism 25 becomes the front-back direction of the main body 1 (the direction in which the user looks at the water purifier). Therefore, a compact and compact water purifier with less pressure can be obtained. Further, since the longitudinal axis of the valve mechanism 25 is in the front-rear direction of the main body 1, a connection portion with the water purification materials 23, 24, and 33 is provided on the back surface of the main body 1. This makes it harder for the viewer to look into the eyes, so that the sight is reduced. In a water purifier directly connected to a faucet, a cartridge for accommodating a water purifying material is attached to the back of the main body. In a stationary water purifier, a connection hose for connecting the water purifying material and the main body is provided with a main body. Although the cartridge and the connecting hose are mounted on the back of the unit, the cartridge and the connecting hose are also hard to be seen from the user side, so that the user does not feel pressure or unsightly. As a result, the dead space below the faucet 4 can be effectively used, and workability such as washing with water near the faucet 4 can be improved. In addition, the valve mechanism 25
Is connected directly, the cock part 10 and the valve mechanism 25 can be made as close as possible, and a small and compact water purifier can be provided. Further, since the valve mechanism 25 is provided within the range of the cock portion 10 in the flow direction of the raw water flowing from the faucet 4, not only the horizontal direction but also the height direction can be made compact. Further, since the valve mechanism 25 is provided with the heat dissipating fins 42, the heat dissipating of the spring member 29 for preventing the flow of the hot water into the water purification materials 23 and 24 can be expedited, and the return to the normal state can be expedited. Can be.

[0005]

Next, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view of a faucet direct connection type water purifier. This water purifier comprises a main body 1 and two cylindrical water purification cartridges 2 and 3. On the upper surface of the main body 1 is provided a mounting portion 5 which is detachably mounted on the tap 4 for water supply, and on the lower surface thereof, a drainage portion 6 is provided. A rotation lever 7 for mode switching is mounted on the side surface. Also, the two cartridges 2 and 3
Horizontally and parallel to each other, they are detachably mounted on the back surface of the main body 1. 8 is a tap for water supply.

FIGS. 2 and 3 are sectional views of the water purifier.
In the figure, reference numeral 9 denotes a fitting ring provided inside the mounting portion 5, which fits on the enlarged lower end portion of the faucet 4. Reference numeral 15 denotes a packing provided below the packing, which is in contact with the lower surface of the faucet 4 to prevent the raw water flowing out of the faucet 4 from leaking to the outside. The mounting portion 5 is ring-shaped and has a screw portion on the inner surface. By manually turning the mounting portion 5, the main body 1 is detachably mounted on the lower end of the faucet 4.

In FIG. 3, a cock 10 is provided inside the main body 1. The cock section 10 houses a cock body 12 that switches the flow path by rotating about a rotation axis in a direction orthogonal to the raw water flowing from the faucet 4 by operating the lever 7 inside the cock pipe 11. It is configured. Reference numerals 13 and 14 denote water passages and water passages formed by cutting out the cock body 12. In FIG. 2, reference numeral 17 denotes a water passage that communicates with the water passage 13. The drain section 6 is provided immediately below the cock section 10. Reference numeral 16 denotes a drain pipe attached to the drain section 6.

In FIG. 4, a tube 21 is built in the center of one of the cartridges 2 in the longitudinal direction thereof.
The inside thereof is partitioned by a filter plate 22.
Activated carbon 23 having a large particle size is stored in a space S1 around the tube body 21, and activated carbon 24 having a small particle size is stored in a space S2 separated by a filter plate 22. As described above, by incorporating different types of activated carbons 23 and 24 having different adsorbing abilities into the cartridge 2, the water purification capacity can be increased.

In FIG. 4, a valve mechanism 25 is provided in a water passage from the water pipe 17 to the cartridge 2. The valve model 25 includes a first valve piece 26 and a second valve piece 26.
Of the first valve piece 26, and a second coil spring 29 made of a shape memory alloy interposed between the two pieces 26 and 27 and deformed by the temperature of water.
And a third spring member 30 for resiliently repelling the second valve piece 27. On the side of the valve piece 26, an opening 31 is formed as a bypass which leads to the drain 32 (see FIG. 5). Normally, low-temperature raw water sent from the faucet 4 flows to the cartridge 2 through the water pipe 17 and the valve mechanism 25. As will be described later, when hot water flows, a coil spring 29 made of a shape memory alloy is used.
, The valve mechanism 25 is actuated, and the hot water is supplied to the opening 3
1 and is drained from the drain portion 32.

2, 4 and 5, the direction in which the spring member 29 of the valve mechanism 25 is deformed, that is, the longitudinal axis of the valve mechanism 25 is perpendicular to the rotation axis of the cock body 12, and Since the direction is orthogonal to the flow of the raw water flowing from 4 (the first arrow direction of the water flow route C in FIG. 2), the main body 1 does not become wide. Further, since the longitudinal axis of the valve mechanism 25 is in the front-back direction of the main body 1, the main body 1
A connection portion with the water purification materials 23 and 24 is provided on the back of the device, and this connection portion is less likely to enter the line of sight from the user side, and the appearance is eliminated. 2 and 4, the cock pipe 11 is directly connected to the casing 41 containing the spring member 29 and the valve piece 26, that is, the cock section 10 and the valve mechanism 25 are directly connected. Therefore, the main body 1 can be made compact in the lateral direction. Further, as shown in FIG. 2, since the valve mechanism 25 is provided within the range of the cock portion 10 in the flow direction of the raw water flowing from the faucet 4, it is possible to make the height direction compact as well as the lateral direction. it can. The present invention can be applied not only to a water purifier directly connected to a faucet but also to a stationary water purifier having a connection hose connecting a water purification material and a main body.

The other cartridge 3 contains a hollow fiber membrane filter 33 and a water passage 38 along the inner wall surface. The inlets 34 and 35 of the two cartridges 2 and 3 are connected by a pipe 36. The cartridge 3 is connected via a communication pipe 37 to
The cock 10 communicates with the cock.

As shown in FIG. 4, both cartridges 2, 3
Are mounted on the main body 1 in parallel with each other. The mounting portion 5 is on the bisector N of the cartridges 2 and 3. By arranging the main body 1 and the cartridges 2 and 3 in this manner, the overall shape can be made compact and the balance of the center of gravity of the mounting part 5 mounted on the faucet 4 becomes good. The two cartridges 2 and 3 may store the same water purifying material. However, as in the present embodiment, if different types of water purifying materials such as activated carbon and hollow fiber membrane filters having different water purifying abilities are stored, the water purifying effect can be further improved. Can be given.

In FIG. 2, a drain pipe 16 is provided with a drain port 1.
6a is partially open. In addition, a water stop 18 is provided above the drain pipe 16, and the water stop 18 has an opening 18 a. A plurality of small holes 6a are formed on the lower surface of the drainage section 6. Reference numeral 19 denotes an operation lever. When the lever 19 is rotated, the drain pipe 16 is rotated. As shown in FIGS. 2 and 6, when the lever 19 is operated to make the drain port 16a coincide with the opening 18a, water is drained from the drain pipe 16. Further, as shown in FIGS. 3 and 7, when the drain port 16a is closed by the water stopping body 18, the water spouts out of the small hole 6a in a shower shape.

The water purifier is operated by operating the lever 7 to stop water, raw water, raw water shower, purified water, and backwash.
It is possible to switch between the two modes. Next, each mode will be described.

FIG. 8 shows a water stop mode. The cock body 12 of the cock part 10 closes the faucet 4 side, so that even if the stopper 8 is opened, the raw water does not flow into the water purifier. FIG. 9 shows the raw water mode. The cock body 12
It is pressed against the left side of the cock pipe 11, and in this state, the water outlet 14 of the cock body 12 passes directly through the drain pipe 16, and the raw water sent from the faucet 4 flows down as shown by the arrow A1,
Further, as shown by an arrow A2 in FIG. 3, the water is directly drained from the drain pipe 16 as it is.

FIG. 10 shows a raw water shower mode. The water inlet communicates with the internal space 20 of the drainage unit 6 shown in FIG. 3, and the raw water flows through the small hole 6a as shown by arrows B1 and B2.
Squirts out of the shower.

Next, the water purification mode will be described with reference to FIGS. In the figure, arrow C indicates a water passage route at the time of water purification, and ae indicate passage points of the water passage route. 2 and 3, the raw water flowing from the faucet 4 has its flow changed in the orthogonal direction by the cock body 12, passes through the water pipe 17 (passing point a), and further passes through the valve mechanism 25 (passing point b). ), Enters the inside of one of the cartridges 2, passes through the activated carbons 23 and 24, and then enters the tube 21 (passing point c). As described above, when passing through the activated carbons 23 and 24, the calcium in the raw water is adsorbed and removed.

Next, the raw water passes through the pipe 36 from the pipe 21 and enters the other cartridge 3 (passing point d). The impurities in the raw water are absorbed and removed by the hollow fiber membrane filter 33. The purified water from which impurities have been removed in this way passes through the communication pipe 37 from the water passage section 38 (passing point e), and is drained from the drain pipe 16 as shown in FIG.

Next, the backwash mode will be described. In the figure, an arrow D indicates a water flow route, and I to E indicate passing points. In this case, the cock 10 is in the state shown in FIG. In this state, the raw water flowing from the water passage 13 passes through the communication pipe 37 (passing point a), flows into the water passage 38 of the cartridge 3 in FIG. Then, the liquid enters the inside of the hollow fiber membrane filter 33 (passing point b), and flows into the tube 21 of the other cartridge 2 from the inlet 35 through the pipe 36 (passing point c). That is, in the backwashing, the raw water flows in the opposite direction to the case of the above-mentioned purified water, and the impurities attached to the hollow fiber membrane filter 33 are removed.

Next, the activated carbons 23 and 24 of the cartridge 2
Passes through the valve mechanism 25 (pass point d) and is drained from the small hole 6a (pass point e). In this way,
If the backflush is performed occasionally to remove impurities from the hollow fiber membrane filter 33, the life of the hollow fiber membrane filter 33 can be extended.

Activated carbon 23, 24 or hollow fiber membrane filter 3
Since the dirt adheres to the cartridge 3 and the water purification capacity is reduced, the cartridges 2 and 3 must be appropriately removed from the main body 1 and replaced. In this case, this one
Since each of the cartridges 2 and 3 is independently attached to the main body 1, the cartridge 2 or 3 whose replacement time has come can be individually removed and replaced.

By the way, it is known that antibacterial materials such as silver are coated on the surfaces of the activated carbons 23 and 24 to prevent the propagation of various bacteria. Hot water may be supplied from the faucet 4. However, when hot water is sent to the cartridge 2, the antibacterial material coated on the activated carbons 23 and 24 elutes, and drinking hot water containing the antibacterial material causes a health problem. Therefore, a coil spring 2 made of a shape memory alloy
The inconvenience is avoided by configuring the valve mechanism 25 in which the 9 is interposed. That is, when hot water flows into the valve mechanism 25, the coil spring 29 is heated and expanded, the valve piece 26 is pushed up, and the valve piece 27 is pushed down. Then, the water passage to the cartridge 2 is closed, and the hot water is drained from the drain part 32 through the opening part 31 which is a bypass part. Therefore hot water is activated carbon 2
No antibacterial material is eluted by flowing through 3,24. The deformable member such as the coil spring 29 is not limited to a shape memory alloy, and may be a bimetal or the like as long as it deforms due to a temperature change. When switching from hot water to cold water, the coil spring 29 returns to its original shape and returns to a normal water-purified state.
In particular, the valve piece 26 that opens and closes the bypass side is made up of a coil spring 29 whose spring constant changes with temperature and a normal spring material 2.
At low temperatures, the spring force of the spring material 28 is greater than the spring force of the coil spring 29, and therefore closes the bypass side. At high temperatures, the spring force of the coil spring 29 is greater than the spring force of the spring material 28. Therefore, the bypass side is opened. Therefore, there is an advantage that the expansion and contraction of the spring member 29, that is, the switching of the water passage can be promptly performed with high sensitivity according to the change of the water temperature. Further, according to the valve mechanism 25, when the cartridge 2 is clogged and the internal water pressure on the cartridge side is increased, the valve piece 26 is pushed up by the internal pressure, and the water is discharged from the opening 31 and the drain 32. There is an advantage that can be drained. If the spring force of the spring member 28 is made stronger than the spring force of the coil spring 29 when the coil spring 29 is extended, the spring member 28 is not compressed by the extension force of the coil spring 29 at a high temperature, and the pressure due to the inflow of hot water becomes a predetermined pressure. Until the hot water is drained from the drain portion 32, the hot water can be completely stopped. (See the solid line state in FIG. 4.) Reference numeral 42 in FIG.
Radiating fins that enhance the heat radiating effect of the coil spring 29
Sensitive to temperature changes.

As described above, the valve mechanism 25 prevents the hot water from flowing into the cartridge 2 by discharging or stopping the water from the drain portion 32 by the coil spring 29, but the hot water is switched to the purified water. The state in which the water continues to flow is bad for the water purifier and is not preferable. In particular, if the structure is such that hot water is not drained from anywhere, the user notices an error and the hot water is supplied to the valve mechanism 2 even when switching to cold water flow.
Since the stagnant water stays in the chamber 5, it does not return to the normal state for a while, and the user cannot use the chilled water at all even though the cold water is supplied, and cannot distinguish it from a failure. Therefore, another embodiment is shown as a display means. As shown in FIG. 4, a transparent transparent or through-hole window 40 for recognition is formed in the outer casing 39 of the main body 1. This window 40
Is not limited to the side surface of the outer casing, but can be seen from multiple directions over two or more surfaces on the upper surface.
A part of the valve mechanism 25 (for example, the shape memory coil spring 2)
9 is formed of a transparent material, and the spring material 28, the coil spring 29 or the valve piece 2 is formed.
By observing the movements of the heaters 6 and 27 from the window 40, it is possible to grasp the flow state of the hot water in the valve mechanism 25 and to switch the hot water to cold water so that the user does not have an adverse effect on the water purifier. Can be done. In this case, the display means for recognizing hot and cold water is the spring material 28, the coil spring 29 or the valve piece 2.
6, 27. If used as a display means, a deformable member such as a coil spring 29 that deforms due to temperature may not be provided in the valve mechanism 25 but may be provided in a part that is visible from the valve mechanism 25 in a visible state.

FIG. 11 shows a configuration in which a thermosensitive element 43 whose color changes due to a change in temperature is attached or applied to a position corresponding to the window 40 of the valve mechanism 25. In this case, the display means is the thermochromic element 43.

FIG. 12 shows that a heat conducting member 44 such as aluminum is connected to the outer casing 39 of the main body 1 and the valve mechanism 25.
, And a thermosensitive element 43 as a display means is directly adhered or applied to the outer casing 39. The place where the thermosensitive color changing element 43 is attached or applied is not limited to the vicinity of the valve mechanism 25 but may be any place near a water passage through which hot water passes.

Further, as a display means for recognition, a power supply unit such as a power generator or a button battery or a solar cell which can supply power by a water flow from a faucet is provided.
A switch may be driven by an element such as a thermistor for transmitting a signal, and a warning light and a temperature display may be considered by a display member such as an LED or a liquid crystal. Of course, if the element exerts the Seebeck effect, the output power may be displayed on a meter. Also, a display using a sound-producing member such as a speaker or a buzzer may be considered.

These displays allow the user to stop the supply of hot water or switch the hot water flow path to the raw water inflow side. In addition, the display means capable of displaying characters can increase recognition by displaying characters.

In the above description, the faucet direct connection type water purifier capable of discharging hot water from the drain portion 32 and the type of water purifier in which hot water is completely discharged without being discharged to the outside of the water purifier have been described. Particularly, in the case of completely stopping water, even if low-temperature normal-temperature water flows in immediately, the hot water stays in the valve mechanism 25, the water pipe 17 and the like.
Reference numeral 9 denotes an extended state, which does not immediately flow into the cartridge 2, and the user does not know the cause and thinks that the water purifier is out of order. The display means is very effective. In addition, for a water purifier without a hot water inflow prevention mechanism, there is a possibility that hot water may flow into the cartridge by the care of the user. It can be stopped and the adverse effect of hot water on the cartridge can be minimized. It should be noted that any display means for recognizing a change in color or the like at the boundary of the temperature of the water flowing through the cartridge is convenient.

FIG. 13 shows a stationary water purifier 45. 55
Are the stationary table 48, the water purification cartridge 46, the purified water discharge section 4
7 and a switching unit connected via an extension hose 50. The switching section 55 includes a rotary switching valve 54 therein. Further, a temperature-sensitive deformable member 51 such as a shape memory alloy, and a valve mechanism 53 having a substantially hemispherical valve piece 52 fitted with the deformable member 51 and protruding in a direction opposite to the water inflow direction are also provided. It is decorated.
When the hot water flows, the valve piece 52 directly contacts the switching valve due to the extension of the deformable member 51, and prevents the flow. In the switching valve 54, a purified water passage 56 and a raw water passage 57 are formed. The switching valve 54 in FIG. 13 is in a water-passing state for purifying water.

A recognition window 60 through which the valve mechanism 53 can be seen is formed in the outer casing 61 of the switching section 55. Further, since the casing 59 of the valve mechanism 53 is formed of a transparent member, the movement of the deformable member 51 and the valve piece 52 interposed in the casing 59 can be visually observed. For this reason, hot water flows into the valve mechanism 53 from the faucet 58, and the valve piece 52 is in contact with the switching valve 54.
The user can recognize that the inflow of hot water has stopped, and even if the hot water is switched to low-temperature normal-temperature water, it does not flow to the water purifier body 49 side, not because of a failure of the water purifier, Since the valve mechanism 53 is at a high temperature due to hot water stagnation or the like,
It can be determined that it does not flow into the water purifier body 49 side,
Anxiety is resolved. The display means is the deformation member 5 of the valve mechanism 53.
1 and the valve piece 52.

The valve mechanism 53 and the switching unit 54 are not limited to those provided at a position separated from the water purifier body 49 and the extension hose 50 as shown in FIG.
It may be on the 9 side.

In the case where the valve mechanism 53 and the switching section 54 are provided on the water purifier body 49 side, when the hot water flows in, the hot water stays in the extension hose 50 and the faucet 5
Even if cold water flows in from 8, the valve mechanism 53 maintains the hot water prevention state for a while. For this reason, the thermosensitive element may be stuck or applied to the extension hose 50, and the state of the temperature can be recognized, which is convenient.

Of course, the valve mechanism 5 for preventing the inflow of hot water
Even if there is no type, the display means for recognizing hot and cold water is provided, so that the user can recognize the inflow of hot water and immediately stop the inflow of hot water, thereby minimizing the adverse effects of hot water. I can do it.

The cock portion 10 changes the flow of raw water flowing from the faucet 4 in the water purification mode to an orthogonal direction, and the rotary cock body 12 having the same direction as a rotation axis. And a cock tube 11 for accommodating the cock body 12. The lever 7 is provided at one end of a rotating shaft of the cock body 12,
At the other end of the rotating shaft, a spring member 29 deformed by a change in water temperature for blocking water flow to the water purification materials 23, 24, and 33, and is resiliently generated by the spring force of the spring member 29.

And a casing 41 forming a water passage in a direction perpendicular to the rotation axis of the shaft 2 and in a direction perpendicular to the flow of the raw water flowing from the faucet 4.
By making the direction of the deformation of 9 and the direction of the water passage formed in the casing 41 coincide with each other, the longitudinal axis of the valve mechanism 25 is moved in the front-rear direction of the main body 1 (the direction in which the user looks at the water purifier).
Therefore, the water purifier can be made compact, compact and less oppressive because the main body 1 does not become wide. Also,
Since the longitudinal axis of the valve mechanism 25 is in the front-back direction of the main body 1,
A connection portion with the water purification materials 23, 24, and 33 is provided on the back surface of the main body portion 1. However, since this connection portion is less likely to be seen from the user's line of sight, the appearance is eliminated. In a water purifier directly connected to a faucet, a cartridge for accommodating a water purifying material is attached to the back of the main body. In a stationary water purifier, a connection hose for connecting the water purifying material and the main body is provided with a main body. Although the cartridge and the connection hose are attached to the back of the unit, the cartridge and the connection hose are also hard to be seen from the user side, so that the user does not feel pressure or unsightly. As a result, the dead space below the faucet 4 can be effectively used, and workability such as washing with water near the faucet 4 can be improved. In addition, since the valve mechanism 25 is directly connected to the cock 10, the cock 10 and the valve mechanism 25 are connected.

Further, since the valve mechanism 25 is provided within the range of the cock portion 10 in the flow direction of the raw water flowing from the faucet 4, not only the horizontal direction but also the height direction can be made compact. Further, since the valve mechanism 25 is provided with the heat dissipating fins 42, the heat dissipating of the spring member 29 for preventing the flow of the hot water into the water purification materials 23 and 24 can be expedited, and the return to the normal state can be expedited. Can be.
