  The water discharge device main body 2 has a base portion 2b that is in contact with a vertical wall surface W and a horizontal portion 2c that extends in the horizontal direction from the base portion 2b, and the horizontal portion 2c has a passage extending in the horizontal direction. A water channel 2a is formed. In addition, a substantially cylindrical connecting fitting receiving portion 2d for receiving the connecting fitting 8 is formed at the base end portion of the horizontal portion 2c, and the innermost portion of the connecting fitting receiving portion 2d is the water discharge device main body 2. It communicates with the inflow port 2e. In addition, a water reservoir 2f having a channel cross-sectional area larger than the inlet 2e is formed inside the water discharger main body 2 following the inlet 2e.

  On the other hand, the water discharger body 2 is fixed to the connection fitting 8 by tightening the set screw 10 in a state where the connection fitting 8 is received in the connection fitting receiving portion 2d. Furthermore, two O-rings 8a are arranged between the connection fitting 8 and the connection fitting receiving portion 2d, and watertightness between them is ensured.

  Moreover, the substantially rectangular opening part 2g connected with the water flow path 2a is formed in the front-end | tip part of the horizontal part 2c. The opening 2g receives the water discharger 4 and is configured such that the water discharger 4 is attached with four screws 12.

  As shown in FIGS. 4 and 5, the water discharger 4 rises at a right angle to the rectangular plate part 4 a attached in the horizontal direction in the opening 2 g of the water discharger main body 2 and the plate part 4 a. And a cylindrical portion 4b having an elongated rectangular cross section. Four holes 4c are formed in the plate portion 4a, and the water discharger 4 is attached to the water discharger main body 2 by screwing the holes 4c into the water discharger main body 2 through screws 12 respectively.

  Moreover, the bottom face is formed in the lower end of the cylindrical part 4b, and the elongate slit-shaped spout 6 is formed in this bottom face. As shown in FIG. 5, the water discharge port 6 is formed in a straight line portion 6 a having a constant width extending in the width direction of the water discharge device main body 2, and substantially formed at both ends of the straight line portion 6 a continuously with the straight line portion 6 a. A circular enlarged portion 6b. In the present embodiment, the straight portion 6a has a length of about 100 mm and a width of about 2 mm, and the enlarged portion 6b is formed in a circular shape having a diameter of about 4 mm.

  On the other hand, as shown in FIGS. 3 and 4, the wall surface on the inlet 2e side of the cylindrical portion 4b constitutes a partition wall portion 14 that functions as a throttle means. The partition wall portion 14 is formed in parallel with the straight line portion 6a of the water discharge port 6, and an isosceles trapezoidal cutout portion 14a with a lower portion is formed at the center thereof. The hot water that has flowed through the water passage 2 a is collected in the center so as to flow into the notch portion 14 a of the partition wall portion 14. In this embodiment, the width of the partition wall 14 is about 104 mm, the length of the bottom side of the notch 14a is about 30 mm, the length of the top side is about 45 mm, and the height is about 6.5 mm. In addition, a slight gap is provided between the upper end of the partition wall 14 and the ceiling surface of the water passage 2a. Therefore, in this embodiment, the length of the notch 14a is about 1/3 of the length of the spout 6. Preferably, the length of the notch is about 25 to about 50%, more preferably about 30 to about 45% of the length of the spout.

  Furthermore, as shown in FIG.2 and FIG.6, the rectification | straightening net | network 16 which is a rectification | straightening means is arrange | positioned in the cylindrical part 4b so that the water outlet 6 and the notch part 14a may be covered. The rectifying net 16 is bent so that its cross section forms a closed curve, and is fitted into the cylindrical portion 4b. That is, the rectifying network 16 is arranged in the cylindrical portion 4b in a bent state so as to form a vertically long rectangular section with a rounded lower end. The hot water flowing through the water passage 2a first flows into the rectifying network 16 through a portion covering the notch portion 14a of the rectifying network 16 or an upper side portion of the rectifying network 16 forming a rectangular cross section. Next, the hot water is discharged from the water outlet 6 through the lower end portion of the rectifying network 16 covering the water outlet 6. For this reason, the hot water passes through one rectifying network 16 and is discharged from the water outlet 6. That is, the portion of the rectifying network 16 through which hot water first passes functions as a first net portion, and the portion through which hot water passes for the second time functions as a second net portion.

  The rectifying network 16 is attached to the water discharger 4 by being fitted into the tubular part 4b in a state bent to a predetermined shape. With this configuration, when the water discharger 4 is removed, both the partition wall 14 and the rectifying network 16 formed integrally with the water discharger 4 can be removed. Thereby, the rectification network 16 can be easily cleaned and maintained.

Next, the effect | action of the water discharging apparatus 1 by 1st Embodiment of this invention is demonstrated.
The connection fitting 8 is screwed and connected to a water supply pipe (not shown) provided on the wall surface W, and the water discharger main body 2 is coupled to the connection fitting 8 by a set screw 10 and fixed to the wall surface W. Hot water supplied from the water supply pipe flows into the water reservoir 2f through the connection fitting 8 and the inflow port 2e. Since the flow path cross-sectional area of the water reservoir 2f is sufficiently larger than the flow path cross-sectional area of the inflow port 2e, the flow rate of the hot water flowing in from the inflow port 2e temporarily decreases in the water reserving part 2f. Thereby, the disturbance of the flow of the hot water which flowed in from the inflow port 2e is reduced.

  The hot water flowing into the water reservoir 2f reaches the partition wall 14 through the water passage 2a. The hot water that has reached the partition 14 is collected toward the notch 14a formed in the center of the partition 14 and flows into the cylindrical part 4b mainly through the notch 14a. At this time, most of the hot water passes through a portion covering the notch portion 14 a of the rectifying network 16. Moreover, a part of hot water passes between the upper end of the partition part 14 and the ceiling surface of the water flow path 2a, passes through the upper end surface of the rectifying net 16, and flows into the cylindrical part 4b. The hot water that has flowed into the cylindrical portion 4b passes through the lower end portion of the rectifying network 16 again and is discharged downward from the water discharge port 6. Thus, the hot water is sufficiently rectified by passing through the first net part of the rectifying net 16 and the second net part spaced from the first net part, and is discharged from the water outlet 6.

  The hot water flowing in the water passage 2a toward the partition wall 14 is once squeezed in the width direction of the water discharger main body 2 by the partition wall 14 and then flows around the side edge of the notch 14a. For this reason, a part of the hot water that has passed through the notch 14 a has a velocity component that goes outward in the width direction of the water discharger body 2. Furthermore, since the notch part 14a is formed in the trapezoid shape which the bottom part squeezed, the part of the hot water which passed the notch part 14a is the diagonally downward speed shown to the arrow V in FIG. Get the ingredients. Thereby, the constriction of the flow width of the hot water when the flow rate of the hot water is small is suppressed.

  Moreover, since the enlarged part 6b with which the width | variety was wide is formed in the both ends of the water discharge port 6, the flow resistance of this part is smaller than the flow resistance of the linear part 6a, and the water flow of the both ends of water discharge Becomes stronger. For this reason, the flow of the hot water discharged from the water discharge port 6 is pulled to both ends where the water is strong, and the constriction of the flow width of the hot water when the flow rate of the hot water is small is suppressed. Further, since the flow resistance at both ends of the water discharge port 6 is smaller than the flow resistance at the intermediate portion, a velocity component from the center toward both ends is generated in the hot water flowing into the cylindrical portion 4b. The flow width constriction is also suppressed by the outward velocity component.

  In the water discharge device 1 of the present embodiment, a wide flow was maintained over about 500 mm or more below the water discharge port 6 even at a low flow rate of 15 L / min. Further, at a flow rate of 15 L / min or more, a wide flow could be maintained over a longer distance. Furthermore, even at a large flow rate of 40 L / min, a beautiful waterfall-like flow was maintained without the water discharge spreading greatly.

  According to the water discharge device of the first embodiment of the present invention, since the water discharge port is composed of the straight portion and the enlarged portions at both ends thereof, the water force at both ends of the wide water discharge becomes strong, and the water discharge is performed. Constriction is suppressed, and a wide thin film-like water discharge can be maintained over a sufficiently wide region of the flow rate.

  Further, according to the water discharge device of the present embodiment, since the partition wall portion provided with the notch portion is provided in the center, the hot water that has passed through the notch portion has a velocity component in the direction of spreading in the longitudinal direction of the water discharge port, The spillage of water discharge can be further suppressed.

  Furthermore, according to the water discharge device of the present embodiment, since the flow straightening network is arranged in the vicinity of the water discharge port, the hot water flowing out from the water discharge port is rectified, and uniform water discharge can be obtained from the elongated water discharge port. The disturbance of the flow at the time of a large flow rate is suppressed, and the spread of water discharge at the time of a large flow rate can be suppressed.

  Moreover, according to the water discharging apparatus of this embodiment, since the rectification network is bent and arranged so that the cross section draws a closed curve, the hot water passes through one rectification network twice and has a simple structure. The rectifying effect can be enhanced.

  Furthermore, according to the water discharging apparatus of this embodiment, since the water discharging part can be removed together with the partition wall part and the flow straightening network, the flow straightening network can be easily cleaned and maintained.

  Further, according to the water discharge device of the present embodiment, since the water reservoir is formed in the water passage, the flow rate of the hot water flowing in from the inflow port is reduced, the disturbance of the flow at the time of inflow is suppressed, and uniform water discharge is performed. Obtainable.

  Furthermore, in the water discharge device 1 according to the first embodiment of the present invention described above, there is a gap between the upper end of the partition wall 14 and the ceiling surface of the water passage 2a, but the upper end of the partition wall 14 and the water flow path. The ceiling surface of 2a may contact | abut or it may be comprised watertight between them.

  In the above-described embodiment, the bottom of the notch 14a is substantially flush with the bottom of the plate 4a and the water passage 2a of the water discharger 4, but the bottom of the notch 14a is formed at a higher position. May be.

Further, in the above-described embodiment, the rectifying network is used as the rectifying unit, but a sponge, a coil, or the like can also be used as the rectifying unit.
Moreover, in the embodiment mentioned above, although the water discharging apparatus main body and the water discharging part were comprised separately, you may form a water discharging apparatus main body and a water discharging part integrally.

Further, on the side surface of the cylinder 126b, water inlets 126e and 126f (only the water inlet 126e aligned with the water inlet 126c is shown) are formed at a position aligned with the water inlet 126c and a position aligned with the water inlet 126d, respectively. . When the cylinder 126b is rotated in the cylinder valve unit main body 126a and the water passage 126e and the water passage 126c are aligned, hot water flowing into the cylinder valve unit 124 from the water passage 104c passes through the water passage 126e and the water passage 126c.

It is configured.

Next, the operation of the water discharge device 101 according to the second embodiment of the present invention will be described.
First, water and hot water supplied to the water discharger 101 from the water supply pipe 112 and the hot water supply pipe 114 flow into the water passages 104 a and 104 b of the water discharger main body 104, respectively. The water and hot water that have flowed into the water passages 104a and 104b flow into the hot and cold mixing unit main body 124a. The water and hot water that flowed into the hot water / mixing unit main body 124a are mixed and flow out to the water passage 104c through the inside of the shape memory alloy spring 124d. At this time, the urging force generated by the shape memory alloy spring 124d varies depending on the temperature of hot water passing through the inside. When the temperature of the passing hot water is higher than the set temperature, the urging force generated by the shape memory alloy spring 124d is increased, and the main valve body 124b is moved in the left direction in FIG. As a result, the opening degree of the inlet through which hot water flows in decreases and the opening degree of the inlet through which water flows in increases, so the temperature of the mixed hot water decreases. When the temperature of the hot water is lower than the set temperature, the urging force of the shape memory alloy spring 124d is reduced, and the main valve body 124b is moved rightward. Thereby, the temperature of the mixed hot water rises. By such an action of the main valve body 124b, the temperature of the hot water flowing out to the water passage 104c is adjusted to the set temperature.

  The hot water that has flowed out to the water passage 104 c reaches the cylinder valve unit 126. Hot water that has reached the cylinder valve unit 126 flows into the cylinder 126b. When the cylinder 126b is rotated to a position where a water flow port 126e formed in the cylinder 126b and a water flow port 126c (not shown) formed in the cylinder valve body 126a are aligned, hot water in the cylinder 126b does not pass. The water flows out to the water passage 104d through the water inlet 126e and the water inlet 126c. Hot water that has flowed out into the water passage 104d is discharged from a shower head (not shown) through the water passages 104g and 104h. Moreover, when the cylinder 126b is rotated to a position where the water inlets 126e and 126f are not aligned with the water inlets 126c and 126d, respectively, the water stop state is established.

  On the other hand, when the cylinder 126b is rotated to a position where the water passage 126f (not shown) and the water passage 126d are aligned, the hot water flows out to the water passage 104e. The hot water that has flowed out to the water passage 104e rises through the water passage 104f and then flows into the water passage 104i that extends in the horizontal direction. Since this water passage 104i is configured to be thin, the hot water flowing in from the water passage 104f reaches the groove 102c while spreading thinly. Further, since the flow passage cross-sectional area of the water passage 104f is larger than the flow passage cross-sectional area of the water passage 104i, the water passage 104f acts as a water reservoir, and hot water is rectified while the flow velocity is reduced in the water passage 104f. Is done. The hot water that has reached the groove 102 c first flows into the bent rectifying network 116 through a portion protruding from the groove 102 c above the rectifying network 116. The hot water that has flowed into the rectifying network 116 then passes through the lower part of the rectifying network 116 and is discharged from the spout 102 that opens to the bottom of the groove 102c.

  Thus, since the hot water passes through the rectifying network 116 twice, the flow of the hot water is sufficiently rectified and made uniform. For this reason, even if the water passage 104f opens at a position biased with respect to the water outlet 102, the water discharged from the water outlet 102 becomes a uniform thin film. Moreover, since the enlarged part 102b is formed in the both ends of the water discharge port 102, the water force in the edge part of a thin film-like water discharge becomes strong, and the constriction of the water discharge when there is little water discharge flow volume is suppressed.
