[Detailed description of the device]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a hot and cold water mixing faucet with a water purifier provided in a think tank.

[0002]

[Prior art]

 As is well known, the water in the water supply has been polluted more and more recently, and the pursuit of delicious water has become more and more popular, and various water purifiers using activated carbon, ultraviolet irradiation, etc. have come to be marketed.

A separate type water purifier that is separately placed near the think tank of the kitchen is connected to this type of water purifier through a switching valve provided at the faucet, and raw water is discharged as it is at the switching valve. There is a known device that discharges the purified water that has flowed through the water purifier.

In the conventional hot and cold water mixing faucet, it is difficult to circulate the water purifier to obtain purified water and to discharge the hot water and water mixing faucet again.

[0005] For one of the reasons, conventionally, a water purifier is one that first adsorbs chlorine and the like using activated carbon, but this adsorption performance is, of course, because the adsorption phenomenon is an exothermic reaction. It was thought that it would be unfavorable to combine a hot and cold water mixing faucet with a water purifier, because the temperature would decrease with increasing temperature.

[0006]

[Problems to be solved by the device]

 Therefore, in a hot and cold water mixing faucet with a water purifier as disclosed in Japanese Utility Model Publication No. 51-26354, the main body of the hot and cold water mixing faucet, in which hot water and water are operated by separate stop cocks to form mixed water, Since the water purifier was placed directly, there was a problem that the water purifier was heated by hot water.

In particular, in such a hot water / water mixing faucet with a water purifier, a hose or the like is often used by connecting it to the faucet. In such a case, however, the hot water is transferred to the water purifier by closing the hose or the like. There was a problem that there was a risk of damaging the water purifier by going straight back.

On the other hand, the discharge pipe of an ordinary single lever type hot and cold water mixing faucet is composed of a flexible hose and a shower head provided at the tip of the water hose, and the middle of the flexible hose serves as a sink tank. There is known a structure in which it is suspended in a storage chamber (see, for example, Japanese Patent Publication No. 60-24251, Japanese Patent Publication No. 61-218874, and Japanese Utility Model Publication No. 61-126157). -By adding an under-sink water purifier to the hot water / water mixing faucet, there will be more raw water passages and water purification passages in addition to the water passage, hot water passage and flexible hose. There was a problem that the diameter of the tightening nut for use became large.

[0009]

[Means for Solving the Problems]

 Therefore, the present invention was devised to solve these conventional problems, and the main points are: 1) a water passage communicating with a water pipe and a hot water passage communicating with a water heater. And a long spout pipe that discharges hot and cold water, are integrated in the hot and cold water mixer body, and a single lever type hot and cold water tap that mixes and switches hot water with a movable disk and a fixed disk. Is provided on the top plate of the think tank, and the water passage of the body of the hot and cold water mixing faucet has a handle which is shorter than the single lever and protrudes from the body, and the single lever of the hot and cold water mixing faucet is also provided. Use the water discharge by closing the raw water passage through a water shut-off valve dedicated to water discharge, connect the raw water passage to the inlet of the water purifier made of activated carbon, etc., and to the outlet of the water purifier. Communicate the water purification passage to the water discharge pipe, The passage, the hot water passage, the raw water passage, and the purified water passage are each composed of only four pipes, which are fixed to the passage mounting portion provided on the main body of the hot and cold water mixing faucet and are bundled and extend downward. The water purifier is installed in the storage room of the think tank, and it is operated by only the single lever and the two handles, and the passage mounting portion is formed into a chamber having a circular outer periphery and approximately four equal parts. A hot water / water faucet with a water purifier provided in a sink tank is characterized in that a top plate tightening nut is reduced in diameter by fixing one of the pipe lines to each of these chambers.

[Embodiment of the invention]

 The present invention will be described in detail with reference to the embodiments shown in the accompanying drawings.

FIG. 1 is a conceptual diagram of an embodiment of the present invention, FIG. 2 is a detailed cross-sectional view of an essential part of FIG. 1, FIG. 3 is a cross-sectional view of 1 to 1 of FIG. 2, and FIG. 4 is 2 to 2 of FIG. FIG. 5 is a sectional view, FIG. 5 is a sectional view taken along line 3-3 of FIG. 2, and FIG. 6 is a sectional view taken along line 4-4 of FIG. 2 (provided that 1-1 is a Roman numeral in the figure).

The outline of an embodiment of the present invention will be described. A is a mixing faucet body equipped with a gooseneck type discharge pipe 1, and is attached to, for example, a top plate of a think tank. The mixing faucet body A has a single lever type mixing faucet B and a water stopcock. C and C are mounted so that their axes face each other substantially horizontally.

Below the mixed faucet body A, a water passage 2 communicating with a water pipe, a hot water passage 3 communicating with a water heater (not shown), and a separate unit installed in a storage room of a think tank, for example. The raw water passage 4 communicating with the inlet of the water purifier D, and further the water purifying passage 5 communicating with the outlet of the water purifier D are constituted by pipes and are respectively extended.

Therefore, since the stop cock C and the water purifier D are communicated with each other through the raw water passage 4 and the discharge pipe 1 and the water purifier D are communicated with each other through the water purification passage 5, when the purified water is discharged, the mixture is mixed. If tap B is closed and tap C is opened, tap water is discharged from water passage 2 → tap C → raw water passage 4 → water purifier D → water purification passage 5 → water discharge pipe 1. To do.

Then, after closing the stop cock C, the mixed faucet B is opened at the position of water (minimum temperature) and the purified water in the discharge pipe 1 is drained for a few hours. The purified water between the water discharge pipe 1 and the base of the water discharge pipe 1 can be sealed with the raw water in the water discharge pipe 1.

As a result, it is possible to prevent contamination of a large amount of residual purified water, especially in the purified water passage 5. When the mixed water or tap water is discharged as it is, the stop cock C is closed and the mixed water tap B is opened at the predetermined mixing position, that is, the normal operation of the mixed water tap B can be performed. For example, mixed water or tap water is introduced from the mixed tap B into the water discharge pipe 1 and discharged.

Next, each part will be described in detail. The mixed faucet body A is configured as follows.

That is, in FIG. 2, a mixing faucet tube portion 6 for mounting the mixing faucet B is formed on the right side, and a water discharging pipe tube portion 7 for rotatably mounting the water discharging pipe 1 is formed above. Is formed, and on the left side there is formed a water stopper mounting portion 8 for mounting the water stopper C, and further on the lower side there are a water passage 2, a hot water passage 3, a raw water passage 4 and a purified water passage 5 which are tubular bodies. A passage mounting portion 9 to be mounted is formed. The main body A of the mixed faucet is integrally made of a bronze casting.

A vertical bottom wall 10 is formed in the mixing plug cylinder portion 6, and the bottom wall 10 has water, hot water and mixed water communication holes like a normal hot and cold water mixing faucet. 10a, 10b and 10c are opened, and a cartridge 15 which will be described later is adjoined so as to match these communication holes 10.

A horizontal partition 11 is provided at the center of the bottom wall 10 in the vertical direction to divide the mixing faucet main body A into approximately two parts in the vertical direction. The two vertical partitions 12 and 12a are formed, and the lower part of the main body A of the mixed faucet is divided into four.

Therefore, the partition wall 11 forms the water discharge conduit chamber 7a above the main body A of the mixed faucet. Moreover, the water discharge conduit chamber 7a forms a space for the water discharge pipe cylinder 7.

Further, a water passage chamber 2a and a hot water passage chamber 3a are formed by the vertical partition wall 12 below the mixed faucet body A, and a raw water passage 4a and a purified water passage 5a are formed by the vertical partition wall 12a. Has been done.

The water passage chamber 2 a communicates with the water passage 2, the hot water passage chamber 3 a communicates with the hot water passage 3, and the raw water passage chamber 4 a communicates with the raw water passage 4. Particularly, the purified water passage chamber 5a communicates with the purified water passage 5 and the water discharge conduit chamber 7a, respectively.

The water passage 2, the hot water passage 3, the raw water passage 4 and the purified water passage 5 are bundled together and extend downward.

The water passage chamber 2a communicates with the water communication hole 10a of the bottom wall 10 and the opening / closing hole 13 of the water stopcock C, and the opening / closing hole 13 is the upper end of the vertical partition 12a. It is open at the side.

Next, the mixed faucet B is configured as follows.

That is, the mixed faucet B is equipped with a normal single lever 14, but the movable disk 16 housed in the cartridge case 15 is fixed to the fixed disk 17 by the single lever 14. It is designed to slide against. The cartridge case 15 is pressed against the bottom wall 10 by a protective cover 18. The protective cover 18 is screwed to the mixing faucet tube portion 6.

Next, the water stopcock C is configured as follows.

That is, this water stopcock C is a normal faucet with a makeup cover 19, and the opening / closing hole 13 is opened and closed by the kelep 20 so that the water passage chamber 2a is the primary side and the raw water passage chamber is 4a is the secondary side.

A selection 22 is engraved on the other end of the screw shaft 21 to which the kelep 20 is attached, and the makeup cover 19 is fitted through the selection 22. A handle 23 is fixed to the cover 19.

Therefore, when the handle 23 is rotated, the screw shaft 21 is screwed back and forth, whereby the kelep 20 is moved and the opening / closing hole 13 is opened / closed.

Next, the water purifier D is configured as follows.

That is, the water purifier D is a normal one, which is of a filtration type using various types of activated carbon or bubble ceramics, a sterilization type by ultraviolet irradiation, and a soft water type of an ion exchange resin. Or a fine filter type such as a polyethylene porous hollow fiber membrane.

[0034]

[Effect of the invention]

 According to the present invention, the hot and cold water mixing faucet is provided on the top plate of the think tank, and the water purifier is provided in the storage room below the think tank. Therefore, even if hot water is spouted from the hot and cold water mixing faucet for a long time, it is made of activated carbon or the like. The water purifier is completely unaffected by this heat. As a result, the quality of the water purifier is not deteriorated or damaged.

Since the hot and cold water mixing faucet is provided on the top plate of the think tank to form a single lever, and the water stopcock with a handle shorter than the single lever is provided on the hot and cold water mixing faucet body, it is simple. It does not take up a lot of space, and it looks good in the vicinity of the think tank, and because it has only two levers for the hot and cold water mixing faucet and the handle for the water stopcock, it is easy to operate and cleans water. It is possible to prevent operation mistakes on the vessel.

That is, originally, both the operation lever of the hot and cold water mixing faucet and the handle of the water stop valve are provided in the hot and cold water mixing faucet body, and normal water (raw water) and purified water are discharged from the same water discharge pipe. However, there is no difference in temperature and it is difficult to distinguish between the two types of water, and it is easy for operation mistakes to occur.However, in the present invention, the water shutoff is a dedicated water purification that is used separately when the water discharge by the single lever of the hot and cold water mixing faucet is closed. Also, since the single lever and the handle are two long and short operation bodies, there is no operation error in the clean water discharge. As a result, the life of the water purifier is not shortened by washing with purified water, and it is also convenient for drinking, cooking water, etc.

Since the hot and cold water mixing faucet is a single lever type water mixing faucet having a movable and a fixed disc, unlike a Kelep type water faucet with a large water discharge amount, there is no abnormal increase in water pressure in the water discharge of the water discharge pipe, and Since the water purifier is installed in the storage room of the think tank, high-temperature raw water does not flow back to the water purifier and, in addition, does not damage the water purifier.

That is, a two-valve hot and cold water mixing faucet using a general Kelep type water stop has a characteristic that the flow rate rapidly increases depending on the pressure of the flue water. If the water faucet is closed at the same time with the water faucet at the same time when it is fully opened, the water pressure in the discharge pipe will rise abnormally and you will win. As a back pressure on the outlet side, this abnormal increase in water pressure has an effect, and although it is of the original stop type, a water purifier made of, for example, a synthetic resin must be used as a pressure-resistant container. If it is composed of hollow fiber membranes, it will deform the hollow fiber membranes and damage the water purifier as a whole.

However, in the present invention, since the hot and cold water mixing faucet is composed of the single lever type having the movable and fixed disks, it has the characteristics of suppressing a rapid increase in the flow rate and suppressing the maximum flow rate. Therefore, originally, the abnormal rise of water pressure in the water discharge of the water discharge pipe as described above is suppressed as much as possible, and of course, there is no influence due to heat transfer or convection of hot water. No damage.

At the time of operating the hot and cold water mixing faucet, while the raw water is being spouted from the spout pipe to which a hose or the like is being spouted, even if the spouting pressure becomes abnormally high by squeezing the tip of the hose In the storage room of the think tank, a so-called separate type is provided separately in a U-shape with the water purifier facing downward, and the raw water passage is branched via a water shutoff valve to seal the water. As described in Japanese Utility Model Publication No. 51-26354, there is no risk of high-pressure raw water or sewage flowing back into the water purifier, and damage to the water purifier is avoided as much as possible compared to the Kelep type stopcock. it can.

Originally, a hot and cold water mixing faucet requires a comparatively wide installation space, but it is a single lever type, and furthermore, a water purifier is not directly installed in this hot and cold water mixing faucet, and it is installed in a storage room of a think tank. Since it is provided, a space like space can be left near the hot and cold water mixing faucet. In particular, it is convenient when the water purifier is not used (for example, in winter).

The respective water passages, hot water passages, raw water passages, and purified water passages are fixed to passage passages provided on the main body of the hot and cold water mixing faucet and are bundled together to extend to the lower storage chamber. Therefore, not only is the appearance good, but it is only necessary to install a water purifier and connect and install only each tip side of the four pipelines in the narrowed storage tank of the sink tank. As a result, the installation work of the hot and cold water mixing faucet to the sink tank becomes easy.

Since the passage mounting portion has a circular outer periphery and is constituted by chambers of approximately four equal parts, and one pipe is fixed to each of these chambers to make it compact, it is relatively large. The flexible hose of the diameter is not inserted, and by extension, the top plate tightening nut is made smaller to make the top plate mounting location of the water / water mixing faucet body slim, and it is not necessary to make a large diameter hole in the top plate.
