Description

  The present invention relates to a fixed shower device in which residual water in a shower head does not intermittently drop after shower water stoppage, and more particularly to a fixed shower device that is fixed to a wall or a pipe and performs shower water discharge from above a user.

  The fixed shower device can take hot water of a desired temperature over the whole body from a shower head fixed to the wall of a shower room or a bathroom. The shower head used in such a fixed shower device is larger than that of a hand shower, and can discharge hot water in a wide range. Therefore, if a fixed shower apparatus is used, hot water pours into the whole body, and it has the feature that a feeling of fulfillment that has taken a bath can be obtained even if it does not reach the bathtub. In addition, a fixed shower, a hand shower, and a body shower can be provided in a single hot water pipe, and these can be discharged simultaneously to obtain more satisfaction.

  As an example of the fixed shower device, Patent Literature 1 describes a shower device in which a hand shower head held on a slide hanger is combined. Further, Patent Document 2 discloses a retrofit shower device that can be easily provided with a fixed shower by removing an existing hand shower nozzle hose and attaching a pipe portion provided with a shower sprinkler at one end. A mounting method is described.

  Fixed showers have the above features, but also have some drawbacks. For example, fixed showers are placed overhead, so care must be taken not to accidentally take cold water that has accumulated in the piping. In Patent Document 3, this problem is solved by attaching a shower switching handle that is always switched to the hand shower nozzle side when the water stops. There are also known some residual water treatment mechanisms which attempt to solve the problem by discharging the residual water in the pipe and emptying the pipe. Patent Document 4 describes an example thereof.

As a problem that has not been solved in Patent Documents 1 to 4, there is a problem that the residual water in the shower head intermittently drops after the shower has stopped, that is, the chorochoro and the potapota fall. There are also problems such as being mistaken for water leakage, residual water hitting the body, feeling uncomfortable, and degrading the quality.
The objective of this invention is providing the fixed shower apparatus which prevents the intermittent potter drop from a shower head.

  In order to solve the above-mentioned problem, in the fixed shower device according to the present invention, a hot water supply pipe is connected to the back surface of the shower head, and a plurality of water spray holes are formed in the water spray plate on the front surface of the shower head. The diameter of the water spray hole formed in the upper part of the water spray plate separated from the hot water supply pipe was set to be larger than the diameter of the water spray hole formed in the lower part of the water spray plate adjacent to the hot water supply pipe.

  With the above configuration, the hot water at the upper part of the shower head is instantaneously discharged from the sprinkling holes after the shower has stopped. On the other hand, the hot water at the lower part of the shower head is placed inside the shower head because the surface tension of the small-diameter sprinkling holes is large. It is held and does not fall. For this reason, the residual water in the shower head does not fall intermittently.

  Here, the diameter of the water spray holes is perforated so as to become a small diameter sequentially or stepwise from the upper part of the water spray plate to the lower part of the water spray plate, or the upper, middle, Preferably, the plurality of water spray holes are perforated so that the diameter of the plurality of water spray holes gradually decreases in the order of the upper, middle, and lower parts of the water spray plate.

  Further, the thickness of the watering plate having the watering holes drilled is gradually or stepwise increased from the upper part of the watering plate toward the lower part of the watering plate, or the upper part, the middle part, and the watering board. It is preferable to divide into three lower regions, and to increase the thickness of the watering plate stepwise in the order of the upper, middle and lower parts of the watering plate.

  Further, it is preferable that the hot water supply pipe is connected to the back surface and the lower portion of the shower head. With such a configuration, shower water can be discharged from the entire surface of the water spray plate with a uniform water force.

  Further, when the residual water treatment mechanism is attached to the hot water supply pipe, the hot water held at the lower part of the shower head is discharged from the hot water supply pipe by the residual water treatment mechanism, and the inside of the pipe and the shower head become empty. For this reason, when hot water is discharged again, there is no possibility that the cold water accumulated in the piping and the shower head is bathed.

  According to the fixed shower device according to the present invention, residual water in the shower head does not fall intermittently.

  Embodiments of the present invention will be described below with reference to the accompanying drawings. 1 is a sectional view of a fixed shower device according to the present invention, FIG. 2 is a sectional view of a shower head attached to the fixed shower device, and FIG. 3 is a perspective view of the shower head.

  In the fixed shower apparatus, a shower head 1 is attached to an upper portion of a hollow columnar main body 3 fixed to a wall surface 2. The shower head 1 is connected to the main body 3 through a hot water supply pipe 4.

  When this apparatus is described along the flow of hot water, cold water and hot water supplied from the water supply pipe 5 and hot water supply pipe 6 drawn out from the wall surface 2 are connected to the central part of the main body 3 through stop cocks 7 and 8 respectively. The hot water temperature is adjusted by entering the hot water supply pipe 4 through which the hot water mixing tap handle 9 is operated.

  A valve operation unit 10 is provided above the hot water mixing tap handle 9, and by opening the valve operation unit 10, hot water is ejected from the body shower nozzle 11, and is further separated above the valve operation unit 10. When the valve operation unit 12 is opened, hot water is supplied to the shower head 1 via the hot water supply pipe 13 and the hot water supply pipe 4.

  In this embodiment, a residual water treatment mechanism 14 is provided in the middle of the hot water supply pipe 13 as an option. When the hot water discharged from the shower head 1 is stopped, the remaining water treatment mechanism 14 removes hot water remaining in the hot water supply pipe 13 passing through the shower head 1, the hot water supply pipe 4, and the central portion of the main body 3. It discharges outside through a drain hole (not shown) through the inner hollow part.

  As will be described later, the residual water treatment mechanism 14 is closed when the shower water is discharged from the shower head 1 and discharges the residual water by the action of a valve that is opened by the weight of the water remaining in the pipe after the shower is stopped.

  The shower head 1 has a lower portion of the back surface portion 1a extending rearward to form a pipe-shaped portion 1b, and the pipe-shaped portion 1b is rotatably connected to the hot water supply pipe 4 via a ball joint 15. As a result, the angle of the water spray plate 16 provided on the front surface of the shower head 1 can be freely changed according to the preference of the person taking a shower.

  In this embodiment, the water spray plate 16 is divided into three regions. That is, the watering plate upper portion 16a, the middle portion 16b, and the lower portion 16c. A plurality of sprinkling holes 17 having a diameter of 1.0 mm are formed in the upper portion 16a, 0.8 mm in the middle portion 16b, and 0.5 mm in the lower portion 16c.

  Moreover, the thickness of the water spray plate 16 is also thinner at the upper portion 16a of the water spray plate, and gradually increases toward the lower portion 16c of the water spray plate. Here, the uppermost part of the watering plate is designed to be 3 mm and the lowermost part is designed to be 7 mm.

  The hole diameter of the water spray holes 17 is preferably in the range of 0.1 to 2.0 mm, gradually decreasing the water hole diameter from the upper part to the lower part of the water spray plate, or divided into several regions as described above. Groups of the same watering hole diameter can be formed. Also, the thickness of the water spray plate 16 is not limited to the above-mentioned thickness, but preferably increases gradually from the top of the water spray plate toward the lower portion in the range of 1 mm to 10 mm, or It is possible to provide a plurality of regions so that the thickness increases stepwise from the upper part to the lower part of the watering plate.

  As described above, the sprinkling hole 17 near the lower part near the hot water supply pipe 4 has a small diameter and a long length with a large pressure loss, and the sprinkling hole 17 near the upper part far from the hot water supply pipe 4 has a large diameter and a small diameter with a small pressure loss. Since the holes are short, shower water can be discharged from the entire surface of the water spray plate 16 with a uniform water flow. In some cases, the number of water spray holes is small in the number of large water spray holes on the water spray plate upper portion 16a, and more water may be evenly obtained by drilling more as the diameter of the water spray holes decreases.

  Further, when the shower is stopped, water is instantly discharged from the large-diameter sprinkling hole in the upper portion having a small surface tension, and then a large amount of air is sucked in. Therefore, the hot water in the upper and middle portions of the shower head 1 has large and medium diameters. On the other hand, the hot water accumulated in the lower part of the shower head 1 is not discharged because the surface tension of the small-diameter water holes is large. For this reason, the residual water in the shower head 1 does not fall intermittently.

  In the present embodiment, the remaining water in the shower head 1, the hot water supply pipe 4 and the hot water supply pipe 13 is discharged to the outside through the drain valve 23 of the residual water treatment mechanism 14, and is supplied to the shower head 1 and hot water supply. It does not remain in the pipe 4 and the hot water supply pipe 13. 4A and 4B are cross-sectional views of the residual water treatment mechanism. The residual water treatment mechanism 14 arranges the valve 23 in a space formed by screwing the upper and lower flow path forming members 21 and 22 together. A bias spring 24 is mounted between the valve 23 and the flow path forming member 22, and a shape memory spring 25 is mounted between the valve 23 and the flow path forming member 21.

  The shape memory spring 25 is selected so that the spring force increases when the temperature becomes high. When the temperature is low, the flow path 21a of the flow path forming member 21 is closed by the valve 23, and when the temperature of the hot water reaches an appropriate temperature or more, the shape memory spring 25 is extended and the valve 23 moves downward as shown in FIG. The hot water is supplied to the shower head 1 through the flow path 22 a of the flow path forming member 22, the flow path 23 a in the valve 23, the opening 26, and the flow path 21 a of the flow path forming member 21.

  Further, as shown in FIG. 4B, a sphere 28 that closes the hole 27 of the valve 23 with the weight of residual water in the shower head 1, the hot water supply pipe 4, and the hot water supply pipe 13 after the shower is stopped is provided. The hole 27 is opened by being pushed down. Thereafter, when the residual water becomes low temperature, the shape memory spring 25 is contracted, the valve 23 is raised, and the residual water in the pipe is discharged to the outside.

  5 and 6 are cross-sectional views of another embodiment of the residual water treatment mechanism. In the residual water treatment mechanism shown in FIG. 5, when the pressure of the hot water is above a certain level, it is shown in FIG. Thus, when the valve body 31 moves to the right against the spring 30 to open the flow path 32, and the pressure of the hot water is less than a certain level, the elastic force of the spring 30 as shown in FIG. The valve body 31 is moved leftward so that the discharge flow path 33 is opened.

Further, in the embodiment shown in FIG. 6, by manually moving the valve body 41, the drainage flow path 42 is opened as shown in FIG. 6B, and closed as shown in FIG. It is trying to become.
