Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is provided with a faucet body that individually houses a first valve device and a second valve device, and the faucet body is embedded in an installation site such as a counter or a wall surface. Regarding mixed faucets.

[0002]

2. Description of the Related Art In a hot and cold water mixing tap, there is provided a faucet body which individually incorporates at least two valve devices such as a temperature control valve device and a discharge and stop valve device. There is a so-called embedding type that is embedded in etc.
In such a hot and cold water mixed faucet, the faucet body is naturally provided with a hot water supply connection port and a water supply connection port. For example, as shown in FIGS. 6A and 6B, the connection ports 2A and 2B are provided on the back surface and the bottom surface of the faucet body 20.

[0003]

By the way, it is not always easy to secure sufficient front-rear width (D), vertical width, etc. of the internal space at the installation site 10 of this kind of hot and cold water mixing faucet 12. . For example, in the bathroom counter 10 showing an example of the installation site 10, if the front-rear width (D) of the internal space is increased, the front amount of the counter 10 with respect to the back wall 18 increases, and the bathroom empty space is increased. Will be narrowed. In addition, in this type of counter 10, it is general to place shampoo, toilet tools, etc. on the upper surface, but if the vertical width of the internal space is increased, the total height of the counter 10 becomes excessive, However, since the shampoo and the like are hard to reach for users sitting in the washroom, the counter 10 is not convenient to use. Further, as described above, the total height of the counter 10 becomes too large, so that the empty space in the bathroom is narrowed. In addition, in the installation site 10 originally provided in a small room such as a bus unit of a one-room apartment, it is particularly difficult to sufficiently secure the front and rear width and the vertical width of the internal space.

Therefore, in the hot and cold water mixing faucet 12 shown in FIGS. 6 (a) and 6 (b), it is not possible to secure a sufficient working space behind or below the faucet body 20, and the work such as construction and maintenance is not possible. Is difficult. That is, a tool such as a spanner is inserted into a limited work space existing behind or below the faucet body 20 to connect or disconnect the connection ports 2A and 2B with the terminal portion of the pipe 19 or the like. And so on. Particularly, in the hot and cold water mixing faucet 12 in which a plurality of valve devices such as a temperature controller valve device and a discharge water valve device are individually incorporated,
Since the faucet body 20 itself is enlarged in the first place, the working space becomes smaller, and the large faucet body 20 causes the connection ports 2A, 2B and the like to be blind to the operator. There is also.

Further, in this kind of hot and cold water mixing faucet 12, both connection ports 2A and 2B may be provided side by side on one surface such as the back surface or the bottom surface of the faucet body 20, and in such a case,
When performing work with a tool on one of the connection ports 2A,
This tool or the like may inadvertently come into contact with the other connection port 2B or the like outside the work and interfere with this work. Furthermore, FIG.
As shown in (b), when performing each work through a small work opening 91 or the like provided in the counter 10 or the like, the tool 92 is used while avoiding interference with a small peripheral portion of the work opening 91 or the like. Must be reciprocated many times, and each work becomes even more complicated.

Due to various circumstances as described above, in the conventional hot and cold water mixing faucet, it may be difficult to perform the construction and the maintenance efficiently.

It should be noted that a hot and cold water mixing faucet in which a single valve device such as a temperature control valve device is built in a faucet body, and a temperature control mechanism and a discharge and stop mechanism are coaxially compactly integrated into a single valve device. There is a so-called uniaxial type hot and cold water mixing faucet in which this is incorporated in the faucet body. Some of such hot and cold water mixing faucets are provided with a hot water supply connection port and a water supply connection port on the side surface of the faucet body.

However, in such a hot and cold water mixed faucet, when trying to downsize the faucet main body, it is necessary to reduce the number of routings of the internal flow path, so that the side surface of the faucet main body is inevitably inevitable. A connection port for hot water supply and a connection port for water supply are provided.

On the other hand, in the faucet body that individually incorporates at least two valve devices as described above, in order to reduce the routing of the internal flow passage to reduce the size, the faucet body is inevitable. A connection port for hot water supply and a connection port for water supply are provided on the back surface or bottom surface of the. The faucet body of such a form is naturally taken, and the above-mentioned problems have not been paid attention to.

The present invention has been made in view of such circumstances, and an object of the present invention is to provide a hot and cold water mixing faucet capable of efficiently performing construction and maintenance. To do.

[0011]

In order to solve the above-mentioned problems, first of all, the means adopted by the invention of claim 1 is " a temperature control valve device as a first valve device and a second valve device.
Is a hot and cold water mixing faucet that is embedded in an installation site such as a counter or a wall surface, and has a faucet body that individually incorporates the water stop valve device A hot and cold water mixing faucet provided with a connection port for water supply and a connection port for water supply on the other side, the hot water inlet of the temperature control valve device
Hot water supplied from the water inlet of the temperature control valve device
The water to be supplied has a desired temperature by the temperature control valve device.
Of hot water, and through the hot water outlet of this temperature control valve device
Te, with flows out to the hot water flow path of the faucet body, the
The hot and cold water flow path has a branch flow path, and the branch flow path is a pipe.
Characterized in that it is used to connect to a faucet for a bathtub
It is a hot and cold water mixed tap.

According to the invention of claim 1, in the installation site,
It was made based on the knowledge that it is easy to provide a sufficient space on both sides of the faucet body. For example, when the installation site is a wall surface of a bathroom or the like, there is a sufficient empty space in the lateral direction. Further, even if the installation site is a counter, there is a sufficient empty space remaining in the width direction of the counter even if the faucet body is installed.

According to the first aspect of the present invention, it is possible to perform connection work and disconnection work between each connection port and each pipe, etc. by utilizing a sufficient empty space provided on each side of the faucet body. Therefore, construction and maintenance of the hot and cold water mixing faucet can be efficiently performed. In addition, since there is only one connection port in each of the sufficient empty spaces on each side, when performing work with a tool on one connection port, this tool is not There is no interference from the other connection port. From this point as well, the efficiency of construction and maintenance of the hot and cold water mixing faucet can be improved.

Further, according to the invention of claim 1, it is not necessary to provide a connection port on the back surface or the bottom surface of the faucet body, and to dispose a terminal portion of the pipe behind or below the connection port. Therefore,
The installation space of the hot and cold water mixing faucet can be reduced along the front-back direction and the vertical direction of the installation site. Therefore, the faucet body can be installed in an installation space having a small depth or height, and can be installed universally for various installation sites.

Here, in the invention of claim 1, the hot water supply connection port and the water supply connection port are provided on different side surfaces of the faucet body for the following reasons. If both connection ports are provided on one side surface, it is necessary to separate both connection ports to some extent. This is because when both connection ports are close to each other, for example, when one of the connection ports is threaded, or when one of the connection ports is connected to the terminal portion of the pipe,
This is because the other connection port easily interferes with each work. If the two connection ports are separated from each other, the faucet body becomes large in the front-rear direction and the up-down direction, and it may not be possible to install the faucet suitably on a counter or the like having a small depth or height.

The "installation site" of the present invention may be, for example, a counter provided in a bathroom, a washroom, a kitchen, a deck surface, a wall surface or the like. Further, the “first valve device” and the “second valve device” of the present invention include a temperature control valve device for adjusting the mixing degree of hot water and water, and a discharge / stop valve device for controlling at least discharge / stop water. 置等 can be exemplified. Further, the “each connection port” of the present invention may be directly connected to the terminal portion of the pipe, but may be indirectly connected via a functional device such as a “stop cock unit”. . Examples of the "stop cock unit" include not only a stop cock provided, but also one having one or more other functional devices such as a strainer and a check valve together with the stop cock.

Next, the means adopted by the invention of claim 2 is as follows.
"The hot and cold water mixing faucet according to claim 1, wherein the first valve device and the second valve device are provided side by side with each other.

The invention of claim 2 also makes effective use of a sufficient empty space on the side of the faucet body. That is, according to the second aspect of the invention, since the two valve devices are arranged side by side to each other, the lateral width of the faucet body is expanded, and the installation space for the hot and cold water mixing faucet is laterally expanded. However, since this expansion can be absorbed by a sufficient empty space, the hot and cold water mixing faucet can be properly installed. Moreover, if the two valve devices are arranged side by side, the faucet body can be made compact in the front-rear direction and the up-down direction, so that the faucet body can be properly installed in a wider range of installation sites. For example, it can be suitably installed even on a counter having a smaller depth or height.

Next, the means adopted by the invention of claim 3 is as follows.
"The hot and cold water mixed faucet according to claim 1 or 2, wherein the respective axial centers of the first valve device and the second valve device are in the front-back direction or the up-down direction."

For example, the invention of claim 2 also includes a mode in which the axial centers of the two valve devices are arranged side by side in the left-right direction, for example, coaxially. However, according to this aspect, each operation shaft of each valve device must be projected to the left and right, and for example, a projecting portion that projects into the room is provided for the installation site, and each projecting portion of each valve device is provided in this projecting portion. It is necessary to expose the operation shaft. Therefore, if this aspect is adopted, the installation site on which the hot and cold water mixing faucet is to be installed may be limited to a specific aspect such as an aspect having this protrusion.

On the other hand, according to the third aspect of the present invention, since the respective operating shafts of the respective valve devices can be made to project in the front surface direction or the upper surface direction, they can be installed universally in a wider range of installation sites. In the third aspect of the invention, the axis of each valve device may be inclined in the front, rear, up, and down directions.

Next, the means adopted by the invention of claim 4 is as follows.
"The hot water mixing faucet according to any one of claims 1 to 3, wherein the installation site is a counter".

That is, a counter installed in a bathroom, kitchen, washroom, etc. has a shampoo, detergent,
Various items such as toiletries, scrubbers and sponges are planned to be placed. Therefore, this counter is generally elongated in the lateral direction in order to secure a sufficient mounting capacity. And in the invention of claim 4,
Since this counter is selected as the installation site, it is much easier to secure a sufficient vacant space on the side of the faucet body.
The object of the invention can be achieved more reliably.

[0024]

BEST MODE FOR CARRYING OUT THE INVENTION Next, embodiments of the "hot and cold water mixing faucet" according to the present invention will be described in detail with reference to the drawings.

In this example, as shown in FIG. 1, a hot and cold water mixing faucet 12 installed on a counter 10 for a bathroom showing an example of "installation site" according to the invention of claim 4 will be described. Here, the counter 10 of the present example is provided with a faucet 11 for a bathtub and a hot and cold water mixing faucet 12 for a washing place, and the hot and cold water mixing faucet 12 for a washing place is a specific example of the present invention. ing. However, even for faucet 11 for the bath, that apply the present inventions.

As the hot and cold water mixing faucet 12 for the washing place, that is, the main hot and cold water mixing faucet 12, a handle 21 for temperature adjustment is used to adjust the water discharge temperature, and a handle 22 for water discharge is used. An example is shown in which the discharge water is selected, the water discharge amount is adjusted, and the water discharge direction is switched between the currant 23 and the shower 24. In this example, as the water faucet 11 for the bathtub, a "single water faucet" is shown, in which a single handle 13 is rotated to select water discharge stop water and adjust the water discharge amount.

Next, the detailed structure of the counter 10 and the main hot water / water mixing faucet 12 will be described with reference to FIGS. 2 and 3. First, the counter 10 includes a top panel 15 that constitutes an upper surface and a front panel 16 that constitutes a front surface and a lower surface. In addition, in this counter 10, the back wall 18
In addition to reducing the above-mentioned amount, the upper and lower widths are made smaller so that almost the entire area immediately below the faucet body 20 is an empty space continuous with the inside of the bathroom. And this empty space is, for example,
A large washbasin or the like can be completely inserted, and it can be used as an operation space of the water stopcock 52 described later, which is excellent in convenience.

Incidentally, in the mode in which the connection ports 2A and 2B are provided on the bottom surface of the faucet body 20 as in the above-mentioned conventional example, it is difficult to make an almost empty space just under the faucet body 20 in this way. is there. For example, as shown by the broken line in FIG. 3, the lower plate portion 17 and the like are installed immediately below the faucet body 20, and the connection ports 2A, 2B
This is because it is necessary to hide the pipe 19 and the like connected thereto. However, the aspect of the counter 10 is not limited to this example, and, for example, the top panel 15 and the front panel that reaches the floor of the bathroom from the protruding end thereof, or one of the front portions. The part may be provided with a protrusion.

On the other hand, the main hot and cold water mixed faucet 12 includes a faucet body 20 embedded in the counter 10, a temperature control handle 21 and a water discharge stop handle 22 which protrude from the front panel 16 into the bathroom, respectively. The front panel 16 includes a currant 23 that hangs from the lower surface of the front panel 16, and a water stop unit 50. Of these, the faucet body 20 is
A connection port 2A for hot water supply is provided on the left side surface, and a connection port 2B for water supply is provided on the right side surface. Here, each connection port 2A, 2B
Is projected from the faucet body 20. Further, on the left side, a temperature control valve device 25 as a first valve device having an axial center in the front-rear direction is incorporated, and on the right side, as a second valve device having an axial center in the front-rear direction. The water discharge stop valve device 26 of No. 1 is built in, and it is in a state of including the inventions of claims 2 and 3.

Here, in the invention of claim 2, FIG.
As illustrated in FIG. 5, the temperature control valve device 25 and the water shutoff valve device 26 may be coaxially arranged side by side. However, according to this aspect, it is necessary to expose the operating shaft 27 of the temperature control valve device 25 and the operating shaft 27 of the water shutoff valve device 26 to the left and right outside of the counter 10. So, for example,
The counter 10 is provided with a projecting portion 14 and the like, and the operation shafts 27 are exposed to the inside of the bathroom through the left and right side surfaces of the projecting portion 14 and the like, and the handle 2 for temperature adjustment is provided at each exposed end thereof.
1 and the handle 22 for stopping and discharging water are required to be attached.

On the other hand, in the embodiment including the invention of claim 3 as in this example, each operating shaft 27 may be exposed to the front of the counter 10 as illustrated in FIG. Therefore,
It can be suitably installed on the counter 10 having various forms regardless of whether or not it has the protruding portion 14 and the like. Further, in this example, the temperature control valve device 25 and the water shutoff valve device 26.
In the invention of claim 3, the respective axial centers of are oriented in the front-back direction.
It is also possible to orient this axis in the up-down direction or the front-back, up-down, and diagonal directions. In this case, the respective operation shafts 27, 27 are exposed on the upper surface or the inclined surface of the counter 10, and the handle 21 for temperature adjustment and the handle 22 for stopping water discharge are arranged on the upper surface or the inclined surface. Further, the invention of claim 1 includes aspects other than the above, for example, an aspect in which the temperature control valve device 25 and the water shutoff valve device 26 are arranged side by side in the vertical direction of the counter 10.

Here, in this example, as the temperature control valve device 25, "a temperature sensitive element such as a wax element or a shape memory alloy element which is deformed in response to a temperature change is used, and the degree of mixing of hot water and water. It uses a thermostat type valve device that automatically adjusts. However, the temperature control valve device 25 is not limited to the thermostat system, and for example, a valve device of a "system that is manually driven to adjust the mixing degree of hot water and water" can be used.
Further, in this example, a valve device of “sliding valve system configured by using a fixed valve and a movable valve that slide with each other to open and close the flow path” is used as the water stop valve device 26. However, there is a "lift system that opens and closes the flow path by advancing and retracting the valve element with respect to a pair of opposing valve openings" and "a valve opening and a ball-shaped valve element biased toward this valve opening. However, it is also possible to use another system such as a ball valve system in which the valve body and the valve opening are relatively moved to open and close the valve opening.

[0033]

Connection port 2A for hot water supply and connection port 2 for water supply
The check valve 28 is built in B. In this example, since the check valve 28 is built in the both connection ports 2A, 2B in this way, the portion other than the both connection ports 2A, 2B in the faucet body 20, that is, the main part of the faucet body 20, It is not necessary to secure a built-in space for housing the check valve 28. Therefore, although the faucet body 20 has two function parts, that is, the temperature control valve device 25 and the discharge water valve device 26, it has a substantially box-shaped simple shape and is relatively compact. It has become a thing. Therefore, from this point as well, it is considered that the main faucet body 20 can be suitably installed on the counters 10 of various sizes. The check valve 28 may be built in the connecting portion 57, which will be described later, or may be built so as to straddle both the internal space of each of the connection ports 2A and 2B and the internal space of the connecting portion 57.

By the way, in this example, the connection port 2A for hot water supply is provided.
Is connected to the hot water inlet of the temperature control valve device 25 through the hot water supply passage 30, and the connection port 2B for water supply is connected to the water inlet of the temperature control valve device 25 through the water supply passage 31. The hot water supplied from the hot water inlet and the water supplied from the water inlet are turned into hot and cold water having a desired temperature by the temperature control valve device 25, and the hot and cold water flow passage 33 is passed through the hot and cold water outlet of the temperature control valve device 25.
Flow out to. Further, the hot and cold water flowing out to the hot and cold water flow passage 33 flows into the water shutoff valve device 26, and the hot water shutoff valve device 2
According to 6, whether the hot water flows out to the outflow passage 35 on the Karan side which leads to the above-mentioned Karan 23 or to the outflow passage 36 on the shower side which leads to the above-mentioned shower 24, and the discharge water Selection and water discharge adjustment are made.

In the faucet body 20, the hot and cold water flow path 33 has a branch flow path 38, and the branch flow path 38 uses the pipe 39 which is routed above the faucet body 20 and is described above. It is connected to the faucet 11 for the bathtub. As described above, the vertical width of the main counter 10 is small. However, since the faucet body 20 has the connection ports 2A and 2B projecting from the side surfaces, the installation space along the vertical direction of the main hot and cold water mixing faucet 12 is reduced. Therefore, counter 1
In 0, since a sufficient empty space is secured above the faucet body 20, the piping 39 can be smoothly routed using this empty space.

When the handle 13 of the water faucet 11 for the bathtub is rotated, hot and cold water having a desired temperature is discharged by the temperature control valve device 25. As described above, in this example, since the faucet 11 for the bathtub uses the temperature control valve device 25 built in the main hot water / water mixture faucet 12, the structure of the faucet 11 for the bathtub is simplified and compact. of, that have cost reduction, etc. is achieved.

The faucet body 20 is, for example, a top panel 15
Is once removed, and is inserted / fixed in the counter 10 through a work opening formed by opening the upper surface of the counter 10. That is, by fixing the horizontal plate portion 41 of the stay 40 to the rib 29 on the back side of the faucet body 20 with screws, and fixing the vertical plate portion 43 of the stay 40 to the back wall 18 in the counter 10 with screws. , Fixed in the counter 10. However, the mode of the stay 40 is not limited to this example, and the method of fixing the faucet body 20 is not limited to the method of using the stay 40. For example, the faucet body 20 may be directly fixed to the back wall 18 with screws or the like, or the faucet body 20 may be fixed to the counter 10.

According to this embodiment, there is no need to secure a storage space for storing the connection ports 2A, 2B, etc. behind, in front of, above, or below the faucet body 20, so that The installation space becomes smaller along the vertical and longitudinal directions of the counter 10. That is, according to this example, as shown in FIG. 2, the faucet body 20 can be brought into a state of being very close to the back wall 18 or in a state of being substantially in contact with the faucet body 20. The installation space is smaller.

Further, in this example, the terminal portion of the hot water supply pipe 19 is connected to the hot water supply connection port 2A via the water stop unit 50, and the terminal of the water supply pipe 19 is connected to the water supply connection port 2B. The parts are connected via a water stop unit 50. However, in this example, each water stopper unit 50 is installed in advance in the pipe 1
It is arranged in the counter 10 in a state of being connected to the terminal portion of 9, and each water stop unit 50 uses each of the connection ports 2A using the "work port configured by removing the top panel 15", It is directly attached and fixed to 2B. Specifically, a tool such as a wrench is inserted into the counter 10 through this work opening, and the fastening nut 70 rotatably held in the connection portion 57 of the water shutoff unit 50 is attached to each connection opening 2A, 2B. It will be screwed into the male screw part engraved on the outer peripheral surface of the.

At the time of this fixing work, there is only one connection port 2A, 2B on each side of the faucet body 20, and the tool is of sufficient size on each side of the faucet body 20. Can be used in free space. Further, since the work can be performed in a state where the connection ports 2A and 2B and the water stop unit 50 are fully viewed through the "work port formed by removing the top panel 15," this fixing work is efficient. Is done in a regular manner. In this example, the water stopper unit 50 integrated with the pipe 19 is taken out to the outside of the counter 10, and the water stopper unit 50 is directly attached and fixed to the outside of the counter 10. An integrated product of the plug body 20 and the water stop unit 50 may be fixed to the back wall 18 using the stay 40. In this case, the water faucet body 20 which is horizontally long by attaching the water faucet units 50 and the like on both sides
Is required to be inserted into the counter 10. However, since a sufficiently long internal space is formed in the counter 10, this insertion work can be performed smoothly.

In this example, as the water stopper unit 50, the one having the water stopper 52 and the strainer (not shown) is used, but the one having only the water stopper 52 is used.
The check valve 28 described above may be incorporated together with the water stopcock 52. Further, in each of the present inventions, each connection port 2
Connect the end of each pipe 19 directly to A, 2B,
A functional device such as a water stopper may be arranged in the middle of each pipe 19. However, according to this example, the water faucet unit 50 itself is installed on the back wall 18, the top panel 15, or the front panel 16.
Since it is not necessary to fix the hot and cold water mixing faucet 12, the installation work of the hot and cold water mixing faucet 12 can be performed more efficiently. Further, since the water stop unit 50 is also installed in a sufficient empty space on the side of the water faucet body 20, the construction and maintenance of the water stop unit 50 can be performed more efficiently. Further, in this example, as described above, an example in which the water stop unit 50 is indirectly fixed along with the fixing of the water faucet body 20 to the back wall 18 is illustrated. With the fixing, the faucet body 20 may be indirectly fixed.

Further, in this example, the connection ports 2A and 2B,
Although the fastening nut 70 has been illustrated as a fastener for fixing the connection portion 57 of the water stopper unit 50, fasteners of other modes can also be used. For example, a mode using a fastening clip 80 as shown in FIG. 5 can be exemplified. In this aspect, the connecting portion 57 is provided with an abutting flange 81 and an inserting portion 82, and a seal member 83 is attached to the outer peripheral surface of the inserting portion 82, and each connecting port 2A, 2
B has an abutting collar 84 and an annular groove 85.
Then, the insertion portion 82 is fitted into each of the connection ports 2A and 2B,
A fastening clip 80 is locked between the abutting flange 81 and the abutted abutting flange 84 that abut each other, and each connecting portion 57 is connected to each connecting port 2A,
Fix to 2B.

That is, the fastening clip 80 is formed by bending a leaf spring, and has an engaging portion 86 in which upper and lower substantially semicircular plate portions are connected by a substantially U-shaped plate portion. Stop 86
And a pair of upper and lower folded-back portions 87 that project in a substantially V-shape from a pair of upper and lower ends thereof, and a locking groove 88 is formed in an intermediate portion in the width direction. The fastening clip 80 is expanded so that a pair of upper and lower folded portions 87 are separated from each other, and is locked between the abutting flange 81 and the abutted flange 84 that abut each other. Specifically, the fastening clip 80 is fitted so as to straddle the abutting flange 81 and the abutting flange 84, and the abutting flange 81 and the abutting flange 84 are fitted / engaged in the locking groove 88. By stopping,
The connection part 57 is fixed to each of the connection ports 2A and 2B.

As described above, when the fastening clip 80 is used, between the connection ports 2A and 2B and the connection portion 57 of the water stopcock unit 50, or between the connection ports 2A and 2B and the terminal of the pipe 19. Since connection / disconnection with the parts can be performed with one touch, construction, maintenance, etc. of the hot and cold water mixing faucet 12 can be performed even more efficiently. In this aspect, the protective clip 89 is used to prevent the fastening clip 80 from accidentally falling off. The protector 89 is configured by using an elastic body having a substantially U-shaped cross section, and the fastening clip 80 is elastically fitted onto the pair of upper and lower arm portions 90. The function of the protector 89 prevents the fastening clip 80 from falling off even if a tool or the like accidentally contacts the fastening clip 80. However, this Figure 5
In the embodiment shown in FIG. 7, the use of the protector 89 can be omitted.

In each of the above examples, each connection port 2A, 2B
The female type is used as the female type, and the connecting portion 57 connected to the female type is used as the male type. However, these male and female types can be reversed. Furthermore, the connection ports 2A and 2B can be fixed to the connection portion 57 without using the fastening nut 70 or the fastening clip 80. For example, the abutting flange 81 and the abutted flange 84 shown in FIG.
It is also possible to directly screw one male screw portion of A, 2B, or the connecting portion 57 to the other female screw portion.
