Abstract

PROBLEM TO BE SOLVED: To reduce the dispersion of flow velocity, and to drop water discharged to a bathtub under the state, in which a turbulent flow is difficult to be generated, by flowing water discharged from a discharge opening section, in which discharged water is formed in a flat cross section, to the bathtub along the wall surface of the bathtub. SOLUTION: A swollen section 6b formed to the intermediate section of the top face of a lower material 6 inhibits the dispersion of the quantity of water discharged by adjusting a water flow from a hot-water supply piping 4. An upper cover member 5 is pushed up with the discharge of hot and cold water from the hot-water supply piping 4, and rocked upwards up to the state, in which the pushing force of hot and cold water and the weight of the upper cover member 5 balance, and opening dimensions are increased. Accordingly, the opening area of a discharging opening section H is augmented, and the acceleration of the flow velocity of hot and cold water discharged can be reduced. That is, the large fluctuation of the flow velocity of hot and cold water discharged with the variation of the feed of hot and cold water from the hot-water supply piping 4 is prevented, hot and cold water is discharged into a bathtub 1 under the state, in which a turbulent flow is difficult to be generated at all times, and the generation of a large water-fulling sound can be obviated.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a faucet which can be used for filling a bathtub.

[0002]

2. Description of the Related Art Conventionally, as this type of faucet, there is a faucet in which a faucet main body is formed of a cylindrical member, and an outlet of the cylinder, that is, a circular discharge opening is disposed directly downward. Was.

[0003]

According to the above-mentioned conventional faucet, when hot water is discharged in a state where the discharge amount is small, the hot water can be filled relatively quietly, but the filling time becomes long. In addition, there is a problem that the temperature of hot water drops in a cold season. However, if the discharge rate is increased, the difference in flow velocity (speed difference between the column surface and the central portion) in the cross section of the discharged columnar hot water increases, so that turbulent flow is likely to occur, and the flow of the already accumulated hot water is reduced. There is a problem that a loud impact sound is likely to be generated at the time of contact.

[0004] Accordingly, an object of the present invention is to provide a faucet which can solve the above-mentioned problems and which can be gently and quickly filled with hot water.

[0005]

[Means for Solving the Problems]

[Structure] As shown in FIG. 2, the feature of the invention according to claim 1 is that the faucet main body 7 is provided with a discharge opening H where the water to be discharged has a flat cross section and the faucet main body 7 is installed. There is provided a guide means 5a for flowing water discharged from the discharge opening H to the bathtub 1 along the wall surface 1b of the bathtub 1.

As shown in FIG. 3, the discharge opening H has a flattened shape, and the rectifying means S for suppressing the variation of the discharge water amount in the flattened longitudinal direction is provided with the discharge opening. H.

As shown in FIG. 2, the characteristic feature of the third aspect of the present invention is that the discharge opening H
Is provided with a diaphragm means F for increasing or decreasing the opening area.

[0008] As described above, reference numerals are provided for convenience of comparison with the drawings, but the present invention is not limited to the configuration shown in the accompanying drawings.

According to the first aspect of the present invention, the cross section of the hot water discharged from the discharge opening tends to have a flat cross-sectional shape along the wall surface of the bathtub. It is possible to reduce the falling speed as a whole due to the resistance received from a wide contact surface with the surface, and to reduce the variation in the flow velocity due to the thin (flat) cross section, so that the turbulent flow hardly occurs. Become. as a result,
Even if hot water is applied with a large discharge rate, it is difficult to generate an impact sound, and it is possible to apply hot water quietly and in a short time, not only in the bathtub of a private house, for example, the impact sound is transmitted to the next room It can be used more effectively by installing it in an easy-to-use apartment house, a bathtub of a hotel or the like, especially a unit bath or the like.

According to the second aspect of the present invention, since the discharge opening has a flat shape, the faucet can be formed to be thin. For example, the faucet can be arranged along the bathtub surface. This makes it possible to improve the aesthetics as compared with a conventional device that is installed in a state of being greatly extended in the upper space of the bathtub. Furthermore, since the faucet itself does not become bulky, it is hard to obstruct the access to the bathtub. In addition, since the rectification means can suppress the variation in the discharge water amount in the flat longitudinal direction of the discharge opening, the hot water can be dropped and stretched at a nearly uniform flow rate, and the silence at the time of filling the water can be further improved. It becomes possible.

According to the characteristic configuration of the third aspect of the present invention, the opening area of the discharge opening can be increased or decreased according to the amount of discharge water by the throttle means.
Even when the discharge amount is large or small, it is possible to fill the water without greatly changing the flow rate of the discharged hot water. As a result, even if the discharge amount is changed, the above-described silence during the filling is secured. It is possible to do.

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 shows an embodiment of a faucet according to the present invention. A faucet K is mounted along an upper edge of a bathtub 1 and a bathroom wall 2 rising from the upper edge of the bathtub 1. Further, a valve operation knob 3a for discharging hot water or water from the faucet K is provided. In the space behind the bathtub 1 and the bathroom wall 2, a valve 3 provided with the valve operation knob 3a and a hot water supply pipe 4 connected to the faucet K are arranged. Therefore, by opening and closing the valve 3 with the operation knob 3a,
Hot and cold water of a desired temperature can be discharged from the faucet K and stretched on the bathtub 1.

Referring to the faucet K, as shown in FIGS. 2 to 4, the faucet K is composed of a faucet main body 7 having an upper lid member 5 and a lower member 6 which are arranged vertically. The upper lid member 5 and the lower member 6 are both made of metal and, as shown in the drawing, are hinged at one end and formed so as to be swingable around the pivot axis. An opening between the other ends of the upper lid member 5 and the lower member 6 has a discharge opening H having a flat cross section.
Becomes

A round hole 6a corresponding to the hot water supply pipe 4 is formed in the lower member 6 at a position on the other end side from the hinge connection portion. On the other hand, a round hole 1a corresponding to the round hole 6a is also formed on the upper surface of the bathtub 1 to which the lower member 6 is attached. Then, the faucet K and the hot water supply pipe 4 are attached to the bathtub 1 by inserting the ends of the hot water supply pipe 4 extending from the valve 3 into the round holes 1a and 6a, and screwing the outer peripheral portion of the hot water supply pipe 4 A pair of nuts 4b screwed to 4a is attached and fixed so as to sandwich the peripheral edge of the round hole between the bathtub 1 and the lower member 6. Also,
A raised portion 6b is provided at an intermediate portion of the upper surface of the lower member 6 (downstream from the round hole 6a). The raised portion 6b prevents the water flow from the hot water supply pipe 4 from easily gathering naturally at the central portion of the flat discharge opening H, and regulates the flow of the water to form the longitudinal direction of the discharge opening H. This has the effect of suppressing the variation in the discharge water amount in the direction (see FIG. 3). The raised portion 6b corresponds to the rectifying means S. The lower member 6 is formed so as to be thinner toward the downstream side of the raised portion 6b, so that hot water can be discharged smoothly.

The upper lid member 5 is swingably connected to the lower member 6 attached to the bathtub 1 as described above (see FIG. 4), and a state in which the back surface comes into surface contact with the raised portion 6b. It is configured to be the swing lower limit. At the lower limit of the swing, the opening dimension in the thickness direction of the discharge opening H is the minimum dimension. Further, with the discharge of hot water from the hot water supply pipe 4, the upper lid member 5 is pushed up and swings upward until the pushing force and the weight of the upper lid member 5 are balanced, so that the opening dimension increases. As a result, the opening area of the discharge opening H increases, and the increase in the flow rate of the discharged hot water can be reduced. That is, it is possible to prevent the flow velocity of the hot water discharged from the hot water supply pipe 4 from fluctuating greatly in accordance with the increase or decrease of the supply amount of the hot water, and always discharge the hot water to the bathtub 1 in a state where turbulence is unlikely to occur. Can be prevented from occurring. The upper lid member 5 corresponds to the squeezing means F. According to the throttle means F described in this embodiment, since the opening area can be adjusted by using the balance between the amount of hot water supply and the weight of the upper lid member 5, another electric opening area control mechanism is provided. Even if not provided, the above operation can be achieved with a simple configuration. And since it is a simple structure, the hot water supply pipe 4 and the lower member 6 are also exposed by swinging and opening the upper lid member 5 for mounting work and maintenance (for example, cleaning and component replacement) of the faucet K, Without complicated assembly and disassembly work, it is possible to work while visually checking. Further, the gap between the upper lid member 5 and the lower member 6 becomes the flow path Q of the hot water from the hot water supply pipe 4. In the upper lid member 5, the dimension of the gap gradually decreases toward the downstream side. This shape allows the hot and cold water to be discharged while being gradually shaped into a flat state. On the other hand, on the inner circumference of the downstream end of the upper lid member 5, hot and cold water discharged from the discharge opening H to the bathtub 1 is provided.
A water presser 5a (an example of guide means) for guiding along the wall surface 1b of the bathtub 1 is provided over the entire length. Specifically, the water presser 5a has an inclined surface inclined with respect to the direction of hot water passing through the flow path Q (inclining in a direction of guiding the hot water toward the wall surface 1b).

According to the faucet of this embodiment, the valve 3 is controlled by the valve operation knob 3a so that a desired discharge amount is obtained.
The opening operation of the upper cover member 5 automatically adjusts the opening area of the discharge opening H to an appropriate size, and the flat and thin cross-sectional shape of the bathtub wall surface is formed by the water presser 5a of the discharge opening H. Hot water can be discharged along 1b, and as a result, it is possible to suppress variation in the flow velocity in the cross section of the flowing hot and cold water, suppress generation of turbulence, and gently fill the hot water. In addition, since the faucet can be formed to be thin as a whole, the faucet is hardly obstructed to enter and exit the bathtub, and can be attached in a state of being familiar with the shape of the bathtub, so that the beauty of the bathroom can be improved.

[Another Embodiment] Another embodiment will be described below.

<1> As described in the previous embodiment, the throttle means F is an upper lid configured to adjust the opening area by balancing the upward supply water flow from the hot water supply pipe 4 by its weight. For example, as shown in FIG. 5, a biasing member 8 such as a spring (for example, a plate spring or a coil spring) or an elastic band member (for example, a rubber band) is fixed to the upper lid member 5 as shown in FIG. Side (lower member 6
Or the bathtub 1) so that the opening area of the discharge opening can be adjusted by the balance between the urging force of the urging member 8 and the hydraulic power of the supply water. <2> The installation position of the faucet K is not limited to the upper edge portion of the bathtub, and may be, for example, one attached to the wall surface 1b of the bathtub as shown in FIGS. Further, the faucet main body 7 is not limited to the configuration in which the upper lid member 5 and the lower member 6 are hinge-joined so as to be swingable as described in the above embodiment. May be connected to the lower member so that it can slide along. <3> Further, the faucet main body 7 is configured such that the upper lid member 5 and the lower member 6 are formed separately, and for example, as shown in FIG. Lower 9b
It is also possible to configure the flat tube member 9 integrally provided with. Further, the guide means is not limited to the water presser described in the above embodiment. For example, as shown in FIG. 6, the rectification means S for rolling the energy of flowing water and the rectification means S formed so as to be in contact with the bathtub wall surface. The lower portion 9b may be used. Further, the lower member 6 or the lower portion 9b may be formed as a part of the bathtub 1. <4> The rectifying means S is not limited to the swelling portion 6b provided in the intermediate portion of the lower member 6 described in the above embodiment. For example, a swelling portion may be formed on the back surface of the upper lid member 5. Or may be provided on both the back surface of the upper lid member 5 and the intermediate portion of the lower member 6. Alternatively, as shown in FIG. 7, a flat opening shape of the discharge opening may be formed so as to be narrower toward the middle. Furthermore, it is also possible to use both the shape based on the opening and the shape based on the raised portion 6b. However, when the opening shape is narrowed toward the middle,
The shape of the downstream end of the lower member 6 (or the lower portion 9b) is as follows:
It is preferable that the discharge water is formed along the wall surface 1b so as to flow down along the wall surface 1b.
