Disclosure of Invention
However, in the above-described conventional hot and cold water mixing faucet, since the faucet body is generally a cast product, it is necessary to perform casting using a special die for forming a complicated internal flow path of hot water and water on the faucet body and to perform special machining on the inner wall of the faucet body, etc. at the time of manufacturing, which causes a problem of lowering manufacturing efficiency.
In addition, since a complicated flow path for hot water or water is secured in the faucet body, there are problems in that design is degraded due to an increase in the outer dimension of the faucet body (for example, the outer diameter of the faucet body) and manufacturing costs are increased due to an increase in the weight of the faucet body.
In recent years, specifications of hot and cold water mixing faucets required by various installation situations at home and abroad are sometimes different. For example, there are, due to the installation situation: in the case of using a hot and cold water mixing faucet in which the outer dimension in the longitudinal direction of the hot and cold water mixing faucet is longer than the normal specification, or in the case of using a hot and cold water mixing faucet in which the distance between the hot water inlet of the hot and cold water mixing faucet and the axial center of the water flow inlet (the distance between the central axis of the hot water inlet of the hot and cold water mixing faucet and the central axis of the water flow inlet) is longer than the specification, in this case, since the path of the internal flow path from the hot water inlet and the water flow inlet of the faucet body to the discharge port of the faucet body becomes complicated and the path length becomes long, there is a problem that the manufacturing cost increases to secure such an internal flow.
Therefore, it is a desired problem to make the internal flow path of the faucet body as a simple path as possible.
In the above-described conventional hot and cold water mixing faucet, since the faucet body is a cast molded product, the faucet body may be heated to such an extent that a user cannot touch the surface thereof particularly on the surface of the hot water side region of the faucet body or on the surface near the discharge port of the mixed hot and cold water, and therefore, it is necessary to secure an internal flow path such as a water passage for passing water so that the surface of the faucet body does not become hot as much as possible while improving the design of the faucet body.
Accordingly, the present invention has been made to solve the above-mentioned problems of the prior art and the requested spool, and an object of the present invention is to provide a hot and cold water mixing faucet which can be reduced in size of its outer shape and improved in design by forming a simple path for an internal flow path of a faucet body.
In order to solve the above problem, the present invention is a mixed hot and cold water faucet for discharging and stopping mixed hot and cold water in which hot water supplied from a hot water supply source and water supplied from a water supply source are mixed, the faucet including: a cold-hot water mixing valve unit that generates the cold-hot mixed water; a flow rate adjustment valve unit that adjusts a flow rate of the cold and hot mixed water; a cylindrical faucet body having a hot water inlet through which hot water supplied from the hot water supply source flows, a water inlet through which water supplied from the water supply source flows, and a discharge outlet through which the hot and cold mixed water is discharged, the faucet body being formed with a cylindrical portion extending in a longitudinal direction therein, and the hot and cold water mixing valve unit and the flow rate adjustment valve unit being inserted into and housed in the faucet body from one end side and the other end side, respectively; and a flow rate adjustment valve casing that is inserted from the other end side of the faucet body, is watertightly connected to the other end of the cylindrical portion, and holds the flow rate adjustment valve unit, wherein the flow rate adjustment valve unit is held in the cylindrical portion in a state where one end thereof is inserted from the other end side of the faucet body through the flow rate adjustment valve casing, and is provided with an outlet port through which the hot and cold mixed water flowing into the flow rate adjustment valve unit from the hot and cold water mixing valve unit side flows out, and the flow rate adjustment valve casing is disposed between the other end of the faucet body and the other end of the cylindrical portion so that the outlet port of the flow rate adjustment valve unit and the outlet port of the faucet body directly overlap each other, and the flow rate adjustment valve unit further comprises: a cylindrical valve seat member provided in the cylindrical portion and having an outlet port of the flow rate adjustment valve unit formed on a peripheral surface thereof; and a cylindrical valve member coaxially rotatably provided in the valve seat member and having an opening formed in a peripheral surface thereof, wherein the flow rate adjustment valve casing is disposed on the other end side of the valve seat member and the valve member of the flow rate adjustment valve unit, one end of the flow rate adjustment valve casing is watertight connected to the cylindrical portion of the faucet body, the other end of the flow rate adjustment valve casing is watertight connected to the other end of the faucet body, and a water passage communicating a water flow inlet of the faucet body and the mixer valve unit is formed between the other end of the cylindrical portion of the faucet body and the other end of the faucet body, and the water passage is located between the faucet body and the flow rate adjustment valve casing.

Accordingly, the internal flow path of the faucet body can be formed into a simple path, and the outer dimension of the faucet body (for example, the outer diameter of the faucet body) can be reduced, so that the design of the hot and cold water mixing faucet can be improved.
Further, since the water passage is formed in the vicinity of the outlet of the faucet body between the faucet body and the flow rate adjustment valve case by the flow rate adjustment valve case, the hot and cold water mixing faucet can be made without the user feeling hot even if the user touches the surface of the faucet body.
In the present invention, it is preferable that the flow rate adjustment valve unit further includes: a cylindrical valve seat member provided in the cylindrical portion and having an outlet port of the flow rate adjustment valve unit formed on a peripheral surface thereof; and a cylindrical valve member coaxially rotatably provided in the valve seat member, the cylindrical valve member having an opening formed in a circumferential surface thereof, the cylindrical valve member being switchable to either an open valve state or a closed valve state depending on a rotation angle thereof, the open valve state being a state in which the opening of the valve member and the outlet of the cylindrical valve seat member overlap each other in a radial direction of the valve member and the valve seat member, the closed valve state being a state in which the circumferential surface of the valve member closes the outlet of the valve seat member, the flow rate adjusting valve unit having an inflow passage formed therein through which the hot and cold mixed water passing through the hot and cold water mixing valve unit flows into the valve member from a longitudinal direction thereof, and an outflow passage formed therein through which the cold and hot mixed water flows out from the opening of the valve member and the outlet of the valve seat member in the open valve state, the inflow channel and the outflow channel of the flow rate adjustment valve unit are orthogonal to each other.

As shown in fig. 3 to 5, a cylindrical portion 34 extending in a substantially cylindrical shape in the longitudinal direction of the plug body 2 is formed integrally with the plug body 2 in the vicinity of the central portion inside the plug body 2, and has a so-called double pipe structure.
Further, on the inner peripheral surface near one end portion (end portion on the side of the hot and cold water mixing valve case 4) of the cylindrical portion 34, a projection 34a is formed over the entire circumference so that the inner diameter of the cylindrical portion 34 becomes smaller.
In the present embodiment, the plug body 2 is described as being formed in a substantially cylindrical shape, but the plug body is not limited to a cylindrical shape, and may be formed in a cylindrical shape, and for example, the cross section of the plug body may be a rectangular cross section other than a circular cross section or a modified cross section (an elliptical cross section, an oval cross section, or the like).
In the present embodiment, the shower hose connection pipe 30 to which the shower hose 28 is connected is formed to protrude downward below the central portion in the longitudinal direction of the faucet body 2, and the shower hose 28 is connected to the tip end portion of the shower hose connection pipe 30, but the present embodiment has been described above, but as a modification, the shower hose connection pipe 30 may be formed to protrude upward above the central portion in the longitudinal direction of the faucet body 2, and may be a rod member forming a shower pipe extending in the vertical direction in place of the shower hose 28, and be a part of a so-called "shower rod".
Next, the hot and cold water mixing valve unit 6 will be described with reference to fig. 2 to 4 and 6.
Fig. 6 is a perspective view of a mixer valve unit of a mixer faucet according to an embodiment of the present invention.
Here, the cold/hot water mixing valve unit 6 shown in fig. 6 is shown in a state where the mesh member 6c (see fig. 2) covering the hot water side inlet 6a and the water side inlet 6b from the outside is removed.
As shown in fig. 2 to 4 and 6, the hot and cold water mixing valve unit 6 is inserted and housed in the faucet body 2 from one end side of the faucet body 2 (the left end portion in the longitudinal direction of the faucet body 2 shown in fig. 3 and 4), and adjusts and mixes the amount of hot water supplied from the hot water inlet 20 of the faucet body 2 and the amount of water supplied from the water inlet 22 of the faucet body 2, thereby generating hot and cold mixed water and adjusting the temperature of the hot and cold mixed water.
Further, although the structure of the hot and cold water mixing valve unit 6 is the same as the conventional structure, a detailed description thereof is omitted, but if a component incorporated in the hot and cold water mixing valve unit 6 is simply described, a movable valve body that adjusts the opening degrees of the hot water side inlet 6a and the water side inlet 6b (see fig. 6) of the hot and cold water mixing valve unit 6, a biasing spring that applies a force to the movable valve body by the operation of the hot water temperature adjustment dial 10 when the movable valve body is positioned, and a temperature sensing spring that adjusts the applying force applied to the movable valve body in accordance with the temperature of the hot and cold water mixture mixed in the hot and cold water mixing valve unit 6 are incorporated.

As shown in fig. 3, 4, and 10, a plurality of grooves 46c are formed on the outer peripheral surface of the valve seat member 46 over the entire circumference, and the O-rings 38 serving as sealing members are held in the respective grooves 46 c. One axial end surface of the valve seat member 46 (the left end surface of the valve seat member 46 shown in fig. 3 and 4) abuts against one axial end surface of the projection 34a in the cylindrical portion 34 (the right end surface of the projection 34a shown in fig. 3 and 4) that faces the axial end surface, and the inner circumferential surface of the cylindrical portion 34 of the hydrant body 2 and the outer circumferential surface of the valve seat member 46 are held in a water-tight state by the plurality of O-rings 38.
As shown in fig. 2 to 5 and 10, the flow rate adjustment valve unit 12 includes a rotary shaft member 50 having one end connected to the valve member 48 in the axial direction, and the rotary shaft member 50 is connected to the water discharge/stop switching lever 18 via the connection unit 16.
The valve member 48 is switchable between an open state for nozzle spouting in which the nozzle spouting opening 48a of the valve member 48 and the nozzle spouting outlet 46a of the valve seat member 46 overlap in the radial direction of the valve member 48 and the valve seat member 46, an open state for shower spouting in which the shower spouting opening 48b of the valve member 48 and the shower spouting outlet 46b of the valve seat member 46 overlap in the radial direction of the valve member 48 and the valve seat member 46, and a closed state in which the peripheral surface of the valve member 48 closes the outlets 46a and 46b of the valve seat member 46, according to the rotation angle of the spout water switching lever 18 and the rotation shaft member 50.
As shown in fig. 3 to 5 and 10, the flow rate adjustment valve unit 12 is formed with an inflow passage 52 of the flow rate adjustment valve unit 12 through which the hot and cold mixed water passing through the interior of the hot and cold water mixing valve unit 6 flows into the valve member 48 from the longitudinal direction of the flow rate adjustment valve unit 12.
As shown in fig. 3 to 5 and 10, the flow rate adjustment valve unit 12 includes: a nozzle spout outflow channel 54a that flows out from the opening 48a of the valve member 48 and the outlet 46a of the valve seat member 46 in the opened state, or a shower spout outflow channel 54b that flows out from the opening 48b of the valve member 48 and the outlet 46b of the valve seat member 46 in the opened state.
Here, as shown in fig. 10, since the direction F1 of the inflow passage 52 of the flow rate adjustment valve unit 12 is the longitudinal direction of the valve seat member 46 and the valve member 48, and the direction F2 of the outflow passages 54a, 54b is the radial direction outside of each of the valve seat member 46 and the valve member 48, the inflow passage 52 and the outflow passage 54 in the flow rate adjustment valve unit 12 are orthogonal to each other.
In the present embodiment, the flow rate adjustment valve unit 12 for adjusting the flow rate of the hot and cold mixed water has been described as having a function of switching between nozzle spouting and shower spouting, but may be a flow rate adjustment valve unit configured only by a switching valve, an on-off valve, or the like that spouts water only to either of nozzle spouting and shower spouting.
Next, fig. 11 is a perspective view of a flow rate adjustment valve housing of a hot and cold water mixing faucet according to an embodiment of the present invention.
As shown in fig. 2 to 4 and 11, the flow rate adjustment valve casing 14 is a substantially cylindrical member including one end-side connecting portion 56 and the other end-side connecting portion 58, and holds the rotary shaft member 50 and the connecting unit 16 of the flow rate adjustment valve unit 12 therein, the one end-side connecting portion 56 is connected to the other end portion in the cylindrical portion 34 in a state of being inserted from the other end side of the plug body 2 (the right end portion in the longitudinal direction of the plug body 2 shown in fig. 3 and 4), and the other end-side connecting portion 58 is connected to the inner surface of the other end portion of the plug body 2.
Further, grooves 56a, 58a into which sealing members, i.e., O-rings 38 are fitted are formed on the outer peripheral surfaces of the connection portions 56, 58 of the flow rate adjustment valve casing 14 over the entire circumferential span, but openings or the like penetrating the outer peripheral surface of the flow rate adjustment valve casing 14 are not provided.
Further, the outer peripheral surface of the one end side connecting portion 56 of the flow rate adjustment valve casing 14 and the inner peripheral surface of the other end side of the cylindrical portion 34 of the faucet body 2 (the right end portion in the longitudinal direction of the cylindrical portion 34 of the faucet body 2 shown in fig. 3 and 4) are watertightly connected to each other by the O-rings 38 fitted into the grooves 56a, 58a of the connecting portions 56, 58 of the flow rate adjustment valve casing 14, and the outer peripheral surface of the other end side connecting portion 58 of the flow rate adjustment valve casing 14 and the inner peripheral surface of the other end side in the faucet body 2 (the right end portion in the longitudinal direction of the faucet body 2 shown in fig. 3 and 4) are watertightly connected to each other by the O-rings 38.
Thus, as shown in fig. 3 to 5, the flow rate adjustment valve casing 14 is disposed between the other end of the faucet body 2 and the other end of the cylindrical portion 34 such that the nozzle spout outlet 46a of the flow rate adjustment valve unit 12 directly overlaps the downstream nozzle spout outlet 26a of the faucet body 2, and the shower spout outlet 46b of the flow rate adjustment valve unit 12 directly overlaps the downstream shower spout outlet 32a of the faucet body 2.
That is, the flow rate adjustment valve casing 14 functions as a bush for disposing the flow rate adjustment valve unit 12 in the cylindrical portion 34 of the faucet body 2 such that the respective outlet ports 46a, 46b of the flow rate adjustment valve unit 12 and the respective outlet ports 26a, 32a of the faucet body 2 directly overlap with each other.
Next, as shown in fig. 1 and 3 to 5, in the mixer faucet 1 of the present embodiment, the central axis a1 of the nozzle spout 26b of the faucet body 2 and the central axis a2 of the shower spout outlet 32a are set to pass through the middle between the central axis A3 of the hot water inlet 20 of the faucet body 2 and the central axis a4 of the water inlet 22 of the faucet body 2, but may be set to pass through the vicinity of the middle between the central axis A3 and the central axis a 4.
In the present embodiment, the distance L1 (see fig. 3) between the central axis A3 of the hot water inlet 20 of the faucet body 2 and the central axis a4 of the water inlet 22 of the faucet body 2 is preferably set to 90mm or 150mm, for example.
As shown in fig. 1 and 3 to 5, in the mixer faucet 1 of the present embodiment, the center axis a2 of the shower discharge outlet 32a of the faucet body 2 is set to pass through the center O1 in the longitudinal direction of the faucet body 2, but may be set to pass through the vicinity of the center O1.
As a modification, the center axis a5 (see fig. 3) of the nozzle spout outlet 26a may be set to pass through the center O1 in the longitudinal direction of the faucet body 2.
Next, a method of assembling the mixer faucet 1 according to an embodiment of the present invention will be described with reference to fig. 2 to 4.
As shown in fig. 2 to 4, when the mixer faucet 1 according to the present embodiment is assembled, first, the mixer valve housing 4, the mixer valve unit 6, and the mixer valve holding housing 8 are inserted from one end side of the faucet body 2 (the left end in the longitudinal direction of the faucet body 2 shown in fig. 3 and 4), so that the connection portion 36 of the mixer valve housing 4 is watertightly connected to one end side in the cylindrical portion 34 of the faucet body 2 via the O-ring 38, and the mixer valve holding housing 8 is watertightly held at one end in the faucet body 2 via the O-ring 38 so that the hot water passage port 42 of the mixer valve holding housing 8 directly overlaps the hot water inlet port 20 in the faucet body 2.
Thus, the mixer valve unit 6 is supported in the faucet body 2 in a watertight manner by 2 members, i.e., the mixer valve housing 4 and the mixer valve holding case 8, which are separated from each other.
Here, when the hot and cold water mixing valve case 4, the hot and cold water mixing valve unit 6, and the hot and cold water mixing valve holding case 8 are inserted from one end side of the faucet body 2, the 3 components 4, 6, and 8 may be inserted in a state of being assembled in advance as one component, or a single hot and cold water mixing valve case 4 may be inserted first, and then the hot and cold water mixing valve unit 6 and the hot and cold water mixing valve holding case 8 may be inserted in order.
Next, as shown in fig. 2 to 4, the flow rate adjustment valve unit 12, the flow rate adjustment valve casing 14, and the connection unit 16 are inserted from the other end side of the faucet body 2 (the right end portion in the longitudinal direction of the faucet body 2 shown in fig. 3 and 4), so that the valve seat member 46 of the flow rate adjustment valve unit 12 is inserted from the other end side of the cylindrical portion 34 of the faucet body 2 with the valve member 48 attached therein, and these valve seat member 46 and valve member 48 are held in the cylindrical portion 34 in a watertight manner via the O-ring 38.
One end of the flow rate adjustment valve casing 14 is connected to the other end of the cylindrical portion 34 of the hydrant body 2 via an O-ring 38 in a watertight manner, and the flow rate adjustment valve casing 14 is disposed between the other end of the hydrant body 2 and the other end of the cylindrical portion 34.
Thus, the nozzle spout outlet 46a of the flow rate adjustment valve unit 12 and the nozzle spout outlet 26a of the downstream-side faucet body 2 directly overlap each other, and the shower spout outlet 46b of the flow rate adjustment valve unit 12 and the shower spout outlet 32a of the downstream-side faucet body 2 directly overlap each other.
Therefore, the mixer valve unit 6 is disposed so that its downstream side can communicate only with the flow rate adjustment valve unit through the mixer valve case 4, and the flow rate adjustment valve unit 12 is disposed so that its downstream side can communicate only with the discharge flow passages 26 and 32 including the discharge ports 26a and 32a of the faucet body 2.
Further, a hot water passage B1 (see fig. 3 and 8) communicating only the hot water inlet port 20 of the faucet body 2 and the hot water side inlet port 6a of the mixer valve unit 6 is formed in the faucet body 2 of the mixer faucet 1 in these assembled states, and a water passage C1 (see fig. 3 and 5) communicating only the water inlet port 22 of the faucet body 2 and the water side inlet port 6B of the mixer valve unit is formed, so that the water passage C1 is formed between the faucet body 2 and the flow rate adjusting valve housing 14 (see fig. 3 and 4), between the faucet body 2 and the tubular portion 34 (see fig. 3 to 5), between the faucet body 2 and the mixer valve housing 4 (see fig. 3 and 4), and between the faucet body 2 and the mixer valve holding housing 8 (see fig. 3, 4, and 8), respectively.
Accordingly, since the water in the water passage C1 passes through the outermost periphery inside the faucet body 2, the hot/cold water mixing faucet 1 can be made such that the user does not feel hot even if the user touches the surface of the faucet body 2.
According to the mixer faucet 1 according to the one embodiment of the present invention described above, the flow rate adjustment valve unit 12 is held in the cylindrical portion 34 with one end thereof inserted from the other end side of the faucet body 2 through the flow rate adjustment valve housing 14, and is provided with the outlet ports 46a, 46b through which the mixed cold and hot water flowing into the flow rate adjustment valve unit 12 from the mixer valve unit 6 side flows out, and the flow rate adjustment valve housing 14 is disposed between the other end of the faucet body 2 and the other end of the cylindrical portion 34 so that the outlet ports 46a, 46b of the flow rate adjustment valve unit 12 and the outlet ports 26a, 32a of the faucet body 2 directly overlap with each other, and therefore, the flow paths between the outlet ports 46a, 46b of the flow rate adjustment valve unit 12 and the outlet ports 26a, 32a of the faucet body 2 can be formed at the shortest possible.
Accordingly, the internal flow path of the faucet body 2 can be formed into a simple path, and the outer dimensions of the faucet body 2 (for example, the outer diameter Φ 1 (see fig. 5) of the faucet body 2) can be reduced in size, so that the design of the hot and cold water mixing faucet 1 can be improved.
The outer diameter Φ 1 of the plug body 2 is preferably set to about 45mm, for example.
Further, since the water passage C1 is formed in the vicinity of the discharge ports 26a and 32a of the faucet body 2 between the faucet body 2 and the flow rate adjustment valve casing 14 by the flow rate adjustment valve casing 14, the hot/cold water mixing faucet 1 can be made so as not to feel hot even if a user touches the surface of the faucet body 2.
In addition, according to the mixer faucet 1 of the present embodiment, the flow rate adjustment valve unit 12 further includes: a cylindrical valve seat member 46 provided in the cylindrical portion 34 of the plug body 2 and having outlet ports 46a and 46b of the flow rate adjustment valve unit 12 formed on the circumferential surface thereof; and a cylindrical valve member 48 coaxially rotatably provided in the valve seat member 46, the cylindrical valve member 48 having openings formed in a peripheral surface thereof, the cylindrical valve member 48 being switchable between an open state in which the openings 48a and 48b of the valve member 48 and the outlets 46a and 46b of the cylindrical valve seat member 46 overlap each other in a radial direction of the valve member 48 and the valve seat member 46 and a closed state in which the peripheral surface of the valve member 48 closes the outlets 46a and 46b of the valve seat member 46, the flow rate adjusting valve unit 12 having an inflow passage 52 through which the hot and cold mixed water passing through the hot and cold water mixing valve unit 6 flows into the valve member 48 from a longitudinal direction of the flow rate adjusting valve unit 12, and having an opening 48a for nozzle spouting of the valve member 48 and an outlet 46a for nozzle spouting of the valve seat member 46 or an opening 48b for shower spouting of the valve member 48 and a valve seat member 48 in the open state Since the outflow channel from the shower water discharge outlet 46b of the piece 46 is orthogonal to the inflow channel 52 and the outflow channel of the flow rate adjustment valve unit 12, in the open state, the hot and cold mixed water passing through the hot and cold water mixing valve unit 6 can flow into the valve member 48 of the flow rate adjustment valve unit 12 from the longitudinal direction of the flow rate adjustment valve unit 12, and then flow out from the outlet of the valve seat member 46 in the radial direction of the valve member 48 and the valve seat member 46 through the openings 48a and 48b of the valve member 48, and can flow out to the discharge channels 26 and 32 from the discharge ports 26a and 32a of the faucet body 2 directly overlapped with the outlets 46a and 46b of the flow rate adjustment valve unit 12.
Further, since the inflow channel 52 and the outflow channel of the hot and cold mixed water in the flow rate adjustment valve unit 12 are orthogonal to each other, it is not necessary to provide a channel from each of the outflow ports 46a, 46b of the flow rate adjustment valve unit 12 to the downstream side of each of the discharge ports 26a, 32a of the hydrant body 2 in the hydrant body 2, and the hydrant body 2 can be further downsized.
Further, according to the mixer faucet 1 of the present embodiment, since the center axis A1 of the nozzle spout 26b of the faucet body 2 and the center axis A2 of the shower spout outlet 32a pass through the center between the center axis A3 of the hot water inlet 20 of the faucet body 2 and the center axis A4 of the water inlet 22 of the faucet body 2, therefore, the hot water inlet 20 and the water inlet 22 of the faucet body 2 are disposed at positions at substantially equal distances from the nozzle 24 including the nozzle spout 26b of the faucet body 2 and the shower hose connection pipe 30 including the shower spout 32a, therefore, the design of the hot and cold water mixing faucet 1 can be improved, and the user can easily use the nozzle 24 of the faucet body 2 and the shower hose connection pipe 30 from either one of both ends of the hot and cold water mixing faucet 1 in the longitudinal direction.
Further, according to the mixer faucet 1 of the present embodiment, since the center axis a2 of the shower spout outlet 32a of the faucet body 2 passes through the center O1 in the longitudinal direction of the faucet body 2, the shower hose connection pipe 30 of the faucet body 2 to which the shower hose 28 is connected is formed at a position equidistant from both ends in the longitudinal direction of the faucet body 2, so that the design of the mixer faucet 1 can be improved, and the user can easily use the shower hose connection pipe 30 of the faucet body 2 even from either one of both ends in the longitudinal direction of the mixer faucet 1.
