Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water treatment device in which a functional part for treating tap water supplied from a water supply pipe is exchangeably built.

[0002]

2. Description of the Related Art In recent years, in order to satisfy the health consciousness etc. of employers of various faucets, a water treatment device such as a water purifier has been interposed in a water supply path from a water supply source to a water discharge port. Have been done. For example, as shown in FIG. 6, the water purifier 10 is arranged on a valve seat provided with a washing device, that is, on a primary side of a washing valve seat 70.

In this cleaning valve seat 70, a connection pipe 51 leading to a low tank 72 is connected to one connection port 52 of a branch tap 50 constituting a terminal part of a water supply pipe, and the other connection port 53 is connected to a connection port 53. The inlet connection part 15 of the water purifier 10 is connected. Further, a connection pipe 55 leading to the cleaning valve seat 70 is connected to the outlet connection section 16 provided on the lower surface of the water purifier 10, and treated water supplied through the connection pipe 55 is supplied to the shower nozzle of the cleaning device. The structure is such that water is spouted through 74. And this kind of water purifier 10 has a cap 7
The storage unit 11 includes an opening 77 that can be opened to the front by attaching and detaching the storage unit 3 and the like, and a functional unit 40 such as a water purification cartridge that is detachably stored in the storage unit 11.

[0004]

The conventional water treatment device 10 represented by the water purifier 10 has the following problems. That is, in order to constantly maintain the performance of this type of water treatment device 10, it is necessary to periodically replace the functional unit 40. Then, at the time of this replacement work, the branch tap 50
In general, a water stop operation is performed on the housing 11, a water receiver such as a bucket, a basin or the like is arranged below the opening 77 of the housing 11, and the cap 73 is removed.

However, in this water purifier 10, the housing 11 is arranged with its axis substantially horizontal and the opening 7
7 faces the front, the residual water in the storage body 11 flows out in the face direction of the worker, or flows out from the outer surface of the storage body 11 along the connecting pipe 55, and around the cleaning valve seat 70, etc. May spill. In particular, since the cleaning valve seat 70 is electrically driven, wiring 80 to a power outlet is required.
Are routed around the cleaning valve seat 70. For this reason,
From the viewpoint of preventing electric shock and electric leakage, it is important to prevent the residual water from spilling around the cleaning valve seat 70.

When replacing the functional unit 40,
Although the water stop operation is performed on the branch tap 50, for example, a high water pressure equivalent to 1 MPa may be applied to the secondary side of the branch tap 50. Therefore, when the worker attempts to remove the cap 73, the cap 73 may rush vigorously forward due to the high water pressure and directly hit the face of the worker. In particular, since the replacement work of the functional unit 40 is generally performed by a consumer himself, not by an expert such as a contractor, in a state where the consumer has neglected the water stop operation to the branch tap 50, There is a possibility that this replacement work will be performed. In such a case, there is a possibility that the cap 73 pops out more vigorously and the consumer's face or the like is hit hard.

[0007] The present invention has been made in view of such circumstances, and its purpose is not only to facilitate the treatment of residual water, but also to safely replace the functional unit. It is intended to provide a water treatment device.

[0008]

Means for Solving the Problems To solve the above problems, first, the means according to the first aspect of the present invention is described as follows. "A functional part for processing tap water supplied from a water pipe is replaceable. A built-in water treatment device, wherein the functional portion is connected to and supported by a terminal portion of the water supply pipe, and is detachably attached to the main body portion and detached downward with respect to the main body portion. And a detachable part that makes the water treatment machine replaceable.

According to the first aspect of the present invention, the functional section can be replaced by removing the detachable section from the main body section downward.
It is easy to reliably discharge the residual water in the water treatment device downward. If a water receiver or the like is arranged below the water treatment device, the residual water can be properly treated. Further, even when the detachable part is detached and vigorously popped out due to the high water pressure in the water treatment device, the detaching direction of the detachable part is downward of the water treatment device, that is, the floor surface direction. It is safe because it is not a direction.

On the other hand, since the present water treatment device is structured to be directly supported by the terminal of the water pipe, the mounting operation is easy, and at the time of this mounting operation, the dead space around the terminal of the water pipe is required. Can be effectively used as a work space. That is, as shown in the comparative example of FIG. 7, if the water treatment device 10 is
Since it is necessary to use a fixing member 82 such as a stay to support the water treatment device, the construction of the water treatment device 10 requires a great deal of labor and cost. In addition, as a place where the water treatment device 10 is installed, the water treatment device 10 and the fixing member 82 can be arranged without difficulty, the construction work is easy, and further, a place that does not hinder the use of faucet-related equipment such as a washing valve seat. It is common to select a location that is hardly noticeable. Therefore, it may be difficult or impossible to install the water treatment device 10 depending on the conditions of installation places such as a toilet, a kitchen, and a washroom. In the case where the water stopcock 83 or the like provided on the primary side of the water treatment device 10 installed in the middle of the pipe 81 is installed at a higher place than the water treatment device 10, the above-described replacement work is not required. At this time, it is also necessary to treat a large amount of residual water remaining in the pipe portion 85 between the water stopcock 83 and the like and the water treatment device 10.

On the other hand, in the present invention, the water treatment device 10
Is directly supported on the terminal of the water pipe, so that no fixing member is required at the time of construction. In particular, in the case where the "end part of the piping" such as the water stopcock and the branch tap which is originally present is used as it is, this construction is performed more smoothly. In addition, since the dead space around the terminal of the water pipe can be effectively used, it can be installed properly regardless of the installation location.

Here, the “water treatment device” of the present invention includes:
(1) A water purifier that removes unnecessary components such as "calcium" and harmful components such as trihalomethane from tap water to purify water, and (2) converts tap water to alkaline ionized water. "Water quality converter" for converting into acidic ion water or converting to hard water or soft water, (3) "Component adder" for adding useful components such as minerals to tap water, (4)
Examples include a water purifier, a water quality converter, and a component additive device having at least two functions. The tap water treated by the present water treatment device may be supplied directly from a water supply source or may be supplied indirectly via a water heater or the like.

Further, the “terminal part of the water supply pipe” of the present invention includes:
Although it may be a mere terminal unit having no water stopping function, it is desirable that the terminal unit has a water stopping function such as a water stopcock or a branch tap. If the terminal of the water pipe does not have a water stop function, the water stop operation is performed on a water stopcock or branch tap located on the primary side from the terminal of the water supply pipe when replacing the functional part. Need to be applied. Moreover,
At the time of replacement work, it may be necessary to treat a large amount of residual water remaining between a water stopcock or a branch tap provided on the primary side and the water treatment device. On the other hand, if the terminal of the water supply pipe has a water stop function, it is not necessary to perform the water stop operation retroactively to the primary side of the water supply pipe when exchanging the function part, and also, to replace the residual water to be treated. This is because the amount is also reduced.

In the present invention, the structure and the number of constituent members of the "main body" are not particularly limited as long as the detachable portion is detachably attached. For example, the main body may be configured as a single body, or may be configured with two or more members. Further, in the present water treatment device, the detachable portion and the functional portion may be detached separately or simultaneously.

Next, the means adopted by the invention of claim 2 is as follows:
The water treatment device according to claim 1, wherein the attachment / detachment portion is formed in a container shape that accommodates substantially the entirety of the functional portion.

The invention of claim 1 includes, for example, a mode in which the attaching / detaching portion is formed as a lower lid constituting the lower surface side of the water treatment device. There is a possibility that the water will flow out vigorously, and splashes or the like will occur in a water receiver or the like. On the other hand, in the present invention, since the container-shaped attaching / detaching portion can be removed integrally with the residual water by using the same as a cup, the workability of the replacement operation of the functional portion is further improved.

Next, means adopted by the invention of claim 3 is:
It is a "water treatment device according to any one of claims 1 and 2, characterized in that the water treatment device is provided with a drain portion."

According to the third aspect of the present invention, since water can be drained before the detachable portion is removed, the workability of removing the detachable portion and eventually replacing the functional portion is further improved. In addition, by appropriately draining water even in a cold region or the like, freezing and destruction of the water treatment device can be reliably prevented. The location of the water draining section is not particularly limited. However, in order to drain water more efficiently, the draining section is preferably provided at a lower side of the water treatment device, and particularly preferably at the lowermost portion.

Next, means adopted by the invention of claim 4 is as follows:
`` The detachable portion is connected to the main body portion through a seal member in a watertight manner and is screwed to the main body portion, and when the detachable portion is removed, before the screw connection is released. The water treatment device according to any one of claims 1 to 3, wherein the seal by the seal member is opened.

According to the first to third aspects of the present invention, the attaching / detaching portion is fixed to the main body portion by using a locking member such as a hook, or the main body portion and the attaching / detaching portion are inserted and fixed by a set screw. Etc. are also included. However, according to these aspects, when the high water pressure is applied to the inside of the water treatment device, if the locking or the like by the locking member is released, the attaching / detaching portion may jump out vigorously downward. However, even in such a case, according to the present invention, the attachment / detachment portion is protruded in the direction of the floor surface of the installation location, so that it is safe.

According to the fourth aspect of the present invention, the main body and the detachable portion are screwed to each other, and when the functional portion is exchanged, the screwed connection is gradually screwed back so that the detachable portion is removed. We are going to remove it. Before the screw connection is completely released, the seal provided by the seal member interposed between the main body and the detachable portion is released. Thereby, in a state where the detachable portion is still screwed to the main body, the pressure in the water treatment device is released by opening the seal, and the inadvertent popping out of the detachable portion is prevented. Therefore, the safety of the replacement work of the functional unit is further improved. As a specific structure of the screw connection between the main body and the detachable portion, for example, a male screw is provided on one of the main body and the detachable portion, and a female screw is provided on the other, and the screw is directly screwed. One example is a structure in which a cap nut is rotatably attached to one of the main body portion and the attaching / detaching portion, and a male screw is provided on the other, and indirectly screwed by fastening the cap nut and the male screw.

Finally, the means adopted by the invention of claim 5 is as follows:
5. The method according to claim 1, further comprising: an inlet-side connection portion that receives tap water at an upper portion of the main body portion; and an outlet-side connection portion that drains treated water at a side portion of the main body portion. Described water treatment device ".

The inventions of claims 1 to 4 also include a mode in which the attachment / detachment section is provided with an outlet connection section. According to this mode, the secondary-side connecting pipe is attached to the main water treatment device. It is necessary to attach / detach the attachment / detachment section after the attachment / detachment of the connection pipe, or the attachment / detachment operation of the attachment / detachment section may be complicated. In addition, since the connecting pipe is routed around the attachment / detachment part, the attachment / detachment work of the attachment / detachment part may be complicated or the appearance around the water treatment device may be deteriorated.

On the other hand, in the invention of claim 5, since not only the incoming connection but also the outgoing connection is provided in the connection, the attachment / detachment work of the attachment / detachment part is easy and the appearance around the water treatment device is also improved. improves. In addition, since an inlet connection is provided at the top of the main body, when connected to the terminal of the water pipe, a water treatment device is suspended from the terminal, and the terminal is a wasteful space in the first place. The space below can be used effectively. Furthermore, since an outlet connection portion is provided on a side portion of the main body, 2
The piping on the next side can also be routed neatly.

[0025]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, embodiments of a "water treatment device" according to the present invention will be described in detail with reference to the drawings.

First, an example of application to a water purifier for a cleaning valve seat will be described as a specific example of the water treatment device 10 of the present invention with reference to FIGS. In addition, in this example, the "terminal part of the water pipe" to which the present water treatment device 10 is applied is configured using a branch tap 50 protrudingly provided on the wall surface of the toilet. The branch tap 50 has a first connection port 52 connected to a low tank via a first connection pipe 51 and a main water treatment device 10.
And a second connection port 53 to which is connected. Further, the branch tap 50 has a built-in water stop mechanism for opening and closing the second connection port 53 and the like, and an operation section 54 thereof is exposed. However, the “end part of the water pipe” of each invention is a branch tap 5
0, for example, the second connection port 53 as a connection port.
It may be configured by using a water stopper having only a water stopper, or a simple “end of piping” having various forms such as a straight tube or an elbow and not having a water stopping mechanism.

As shown in FIGS. 1 and 2, the water treatment device 10 is configured by screwing and connecting a main body 12 and a detachable portion 13 and has a functional portion 40 inside. Here, the main body portion 12 is formed in a substantially upper lid shape, and has an inlet connection portion 15 at an upper portion and an outlet connection portion 16 at a side portion.

In this embodiment, the upper end of the inlet connection portion 15 is connected to the second connection port 53 of the branch plug 50 using the cap nut 56, whereby the entire connection portion 12 is connected and supported by the branch plug 50. It has become. In addition, the outlet connection portion 16 includes:
One end of the second connection pipe 55 is connected using a cap nut 57. Further, the other end of the second connection pipe 55 is connected to a cleaning device (not shown). In this embodiment, according to the fifth aspect of the present invention, the entrance-side connecting portion 15
And an outlet connection portion 16 is provided on the side. Therefore, it is not necessary to unnecessarily bend the second connecting pipe 55 or to interpose a connecting member having a complicated bent shape such as a U-shape between the outlet-side connecting portion 16 and the second connecting pipe 55. .

Further, in this embodiment, the input side connection portion 15 and the output side connection portion 16 are fixed to the main body portion 12 separately, but in the present invention, the input side connection portion 15 and the output side connection portion 15 are connected. At least one of the portions 16 may be formed integrally with the main body portion 12. However, if the water treatment device 10 is separately provided as in this example, it is possible to accurately cope with the situation of the location of the water treatment device 10. For example,
Depending on the size, shape, etc., of the "terminal part of the water pipe", the entrance-side connecting portion 15 can be replaced with one having a different size, shape, or the like. Specifically, when the “terminal part of the water pipe” is arranged in a horizontal direction unlike this example, it is preferable to use, for example, a substantially elbow-shaped entrance-side connection part 15.

At the lower part of the inner wall of the main body 12, a tubular portion 23 is suspended coaxially with the above-mentioned inlet connection portion 15, and this tubular portion 2
A male screw part 41 on the upper end side of the functional part 40 is screwed into the female screw part 24 engraved on the inner wall of the third. As a result, the functional unit 40 is in a state of hanging down below the main body 12.

The function section 40 is a cartridge having a predetermined filter medium (not shown) housed in a case 43 having openings at both ends, and is entirely detachable from the main body section 12 as a whole. I have. The functional section 40 has an inlet 44 at the upper end of the case 43 for receiving tap water supplied through the branch tap 50 and the inlet-side connecting section 15, and supplies tap water that has passed through the filter medium and has become treated water. An outlet 46 for outflow is provided at the lower end of the case 43. Case 4
The contents in 3 can be changed as appropriate to provide a water treatment device 10 for other uses such as a component adder for adding a beneficial additive to tap water. Further, in the present example, the handling is facilitated by configuring the functional unit 40 in a cartridge shape, but the mode of the functional unit 40 of each present invention is not limited to this. For example, the functional unit 40 may be used as a filter medium, an additive, or the like, and the filter medium, the additive, or the like may be directly stored in the water treatment device 10.

Further, a sealing member 27 such as a packing is fitted in a circumferential groove at an intermediate portion of the inner wall of the main body 12. A female screw portion 25 is provided on the lower end side of the inner wall of the main body 12, and a male screw portion 26 on the upper outer wall surface of the attaching / detaching portion 13 is detachably screwed to the female screw portion 25. Therefore, the main body 12 and the attaching / detaching portion 13 are threadably connected via the sealing member 27 in a watertight manner.

The attachment / detachment portion 13 is formed in a container shape, and has a structure in which substantially the entirety of the functional portion 40 enters into the inside thereof by being screwed to the connection portion 12. A flow path portion 29 is formed between the inner wall surface of the attaching / detaching portion 13 and the outer wall surface of the functional portion 40.
The treated water flowing out of the main body 1
After passing through the inner space 30 of the second order,
Is discharged to the second connection pipe 55 through

In this embodiment, the attachment / detachment portion 13 is formed in a container shape in accordance with the invention of claim 2, but in the inventions of claims 1, 3 to 5, this attachment / detachment portion 13 is shown in FIG. It may be configured in such a substantially lower lid shape. In this case, for example,
The main body 12 is formed in a container shape opening downward, and
What is necessary is just to enter the function part 40 inside 2.

In addition, a drain portion 32 is provided below the detachable portion 13 in this embodiment. The drainage portion 32 is screwed to a stepped cylinder 33 fixed to an opening at the lower portion of the attachment / detachment portion 13 and a female screw portion on the inner wall of the stepped cylinder 33, and is drained in the axial direction of the stepped cylinder 33. And a spindle 34. And the step cylinder 33
The inner wall surface of the small-diameter portion forms a valve seat portion 36, and the small-diameter portion at the upper end of the drainage spindle 34 is a valve body 37 provided with a sealing member such as packing. The valve body 37 is configured to be opened and closed by inserting and removing the valve body 37 from the valve seat 36. The mode of drainage according to the third aspect of the present invention is not limited to the one shown in this example, and may be, for example, a simple plug detachably attached to the lower part of the attachment / detachment unit. The draining spindle 34 is inserted in a state where it is urged in the closing direction, and when an operator or the like applies a valve opening operation, the valve seat portion 36 is opened, and the valve opening operation is stopped or the draining is completed. Then, a device that automatically returns to the valve closed state may be used. Further, in the inventions according to the first, second, fourth and fifth aspects, the drainage portion 32 can be omitted.

In this embodiment, when replacing the functional unit 40, first, the operation unit 54 of the branch tap 50 is subjected to a water stop operation to shut off the flow of tap water into the second connection port 53. Next, after disposing a water receiver or the like below the main water treatment device 10,
Immediately remove the attachment / detachment unit 13 downward, or open the drainage spindle 34 as needed to open the water treatment device 10.
After the remaining water in the inside is drained, the detachable portion 13 is removed downward. The detachable portion 13 is detached by rotating the detachable portion 13 using an operator's hand or a predetermined tool, and screwing the detachable portion 13 downward.

At this time, in this embodiment, the seal by the seal member 27 is released before the screwing of the male screw part 26 and the female screw part 25 is released according to the invention of claim 4. Specifically, as shown in FIG.
The screwing length B is longer than the distance A between the upper end of the seal member 27 and the lower end of the sealing member 27. Therefore, as shown in FIG. Then, even if the seal by the seal member 27 is released, the screw engagement between the male screw portion 26 and the female screw portion 25 is not yet released, and the detachable portion 13 maintains the state supported by the main body portion 12. Therefore, even if a high water pressure is applied to the inside of the water treatment device 10, the high water pressure is applied to the outside through the gap between the male screw portion 26 and the female screw portion 25 while the attaching / detaching portion 13 is supported by the main body 12. Escaped to Then, when the screw engagement between the male screw portion 26 and the female screw portion 25 is completely released, the pressure in the water treatment device 10 is greatly reduced, and the attaching / detaching portion 13 moves downward against the intention of the operator. There is no momentary jump out. still,
This function is performed before the detachment unit 13 is removed, such as “when the operation of the water removal unit 32 is neglected despite necessity” or “when the water treatment device 10 does not have the water removal unit 32”. This is particularly effective in situations where the necessary pressure release is not performed.

Further, the seal structure / screw structure according to the fourth aspect can be used to enhance the performance of the "water drainage portion 32". For example, when the drainage capacity of the drainage portion 32 is low because the hole diameter of the stepped cylinder 33 is small or the like, the atmosphere can be introduced into the water treatment device 10 by the above-mentioned “opening of the seal”. This is because the residual water in the water treatment device 10 can be discharged from the water draining section 32 with great force.

The sealing structure and the screwing structure according to the fourth aspect of the present invention are not limited to the container-shaped attaching / detaching portion 13 but also to the structure shown in FIG.
(A) Attaching / detaching part 1 of another mode such as "lower lid-like"
3 can be suitably applied.

In this example, after the detachable portion 13 is removed, if residual water remains in the detachable portion 13, this residual water is discarded. Then, the functional unit 40 is removed from the main body unit 12 and replaced with a new functional unit 40. In this example, the function unit 40
Although the embodiment in which the functional unit 40 is detached separately from the attaching / detaching unit 13 has been described as an example, as shown in FIG.
It can also be applied to "other modes" that are integrally removed. In this “other mode”, for example, the terminal of the water pipe is
This is effective when it is not possible to secure a sufficient space for attaching / detaching the attaching / detaching portion 13 below the water treatment device 10 due to circumstances such as the presence of the water treating device 10 nearby.

That is, in the embodiment shown in FIGS.
In order to smoothly remove the attachment / detachment section 13, at least “the entire length of the function section 40 and the attachment / detachment section 1
It is necessary to secure a “removable space” having a height corresponding to “the length obtained by adding the total length of the third device”. This is because the attachment / detachment unit 13 must be moved to one end, below the function unit 40, in other words, to a position that does not interfere with the function unit 40.
Cannot be completely removed. On the other hand, according to the embodiment shown in FIG.
Is moved downward slightly, so that the integrated product is free of interference with other parts of the water treatment device 10 and can be completely removed. Therefore, even if the distance between the terminal part of the water supply pipe and the floor surface 47 is short, the replacement work of the function part 40 can be performed smoothly.

In this embodiment, a water purifier for a cleaning valve seat has been described as described above. However, the present invention can be applied to a water quality converter, a component adder, or a water purifier in addition to other types of water purifiers. The present invention is suitably applied to various water treatment devices such as a "water treatment device having at least two types of functions of a vessel, a water quality converter, and a component addition apparatus". Here, FIG. 5 shows, as another specific example of the present embodiment, a so-called “built-in type” water treatment device 10 that is installed at various installation locations such as under a kitchen sink and under a sink. I have. Note that FIG. 5 illustrates a mode in which the water treatment device 10 is connected to and supported by a "water stopcock 60" as another specific example of the "water supply pipe terminal". The form of the “terminal section” is not particularly limited.

The water treatment device 10 has an inlet connection portion 15
Is connected to a connection port 61 of a water stopcock 60 by using a cap nut 56, and is connected and supported by the water stopcock 60 in a hanging manner.
Further, the outlet-side connecting portion 16 is connected to various water taps on the sink and on the sink via a connecting pipe 62. In this example, when a branch tap is used as the terminal of the water supply pipe, the “other connection port” that is not connected to the entrance-side connection section 15 is used.
Can be connected to the same water tap installed on the sink or the washstand, or another water tap via a connecting pipe or the like. Then, the tap water supplied through the other connection port is discharged as untreated tap water, that is, ordinary water.

In the water treatment device 10 which is installed in a narrow place where cleaning is difficult, such as under a sink or a sink, the water treatment device is replaced when the functional unit 40 is replaced. It is desirable to surely prevent the remaining water in the water 10 from scattering and leaking around. Further, in recent years, it is common to place various appliances such as a dish dryer and a dishwasher under a sink or the like. It is important to prevent According to the above example, the scattering and water leakage can be reliably prevented. Also, under this narrow sink or wash basin,
It is difficult to separately install a stay or the like for fixing the water treatment device 10 together with various electric appliances. Therefore, in the above-mentioned example, there is also a great significance in that the device is installed using the water stopcock 60 originally existing under the sink or the like without using a stay or the like. Further, also in the above-described example, the detachable portion 13 may be detached separately from the functional portion 40 or may be detached integrally, but the detachable portion 1 such as under the sink or under the sink.
In places where it is difficult to secure a sufficient space for attaching and detaching 3,
As shown in FIG. 4, it is particularly preferable to adopt a mode in which the unit is detached integrally. The water treatment device 10 can be suitably used as another type such as a type installed on a sink or a wash basin.

Further, the water treatment apparatus of the present invention can be used in a bathtub, such as a unit bath in a one-room apartment.
The present invention can be suitably applied to a case where a large number of faucet-related devices such as a cleaning valve seat, a low tank, a washbasin, and a shower unit are installed in a very small space. For example, even in a space where the cleaning valve seat and the washbasin are installed in close proximity to each other and a branch stopcock or a water stopcock or the like is exposed in a slight gap therebetween, the water treatment device of the present invention is preferably used. Can be installed in This is because, according to the water treatment device of the present invention, it is sufficient to secure a working space for the replacement work of the functional section below the water treatment device.
This is because this operation can be performed smoothly even if the washing valve seat and the washing ball are juxtaposed. Further, in the present embodiment, the aspect provided with a single outlet connection section has been exemplified, but the water treatment device of each invention of the present invention may be provided with two or more outlet connection sections. For example, treated water can be supplied to both the washing valve seat and the basin by a water treatment device installed between the washing valve seat and the basin.

[0046]

As described above, according to the present invention, it is possible to obtain a water treatment device which not only facilitates the treatment of residual water but also allows the replacement work of the functional parts to be performed safely.
