Description

  The present invention relates to a shower apparatus, and more particularly to a shower apparatus that mixes air with hot water supplied from a shower hose to sprinkle water.

  Japanese Patent Laying-Open No. 2006-239106 (Patent Document 1) describes a shower head. The shower head is configured so that air is mixed into the supplied hot water and discharged from the water spray holes. Such an aeration type shower head is expected as an environmentally friendly water-saving shower head because it can reduce the amount of hot water actually discharged by mixing air into the hot water. ing. In such a shower head, it is necessary to provide an air introduction hole in the shower head body for taking in outside air mixed with hot water.

JP 2006-239106 A

  The air introduction hole for taking in outside air has an appropriate size in order to mix an appropriate amount of air into the hot water. That is, if the air introduction hole is too small, the amount of air that can be introduced decreases, and a sufficient amount of air cannot be mixed with hot water. Also, if the air introduction hole is too large, the amount of air introduced into the hot water passage will be too large, making it difficult to uniformly mix the air with the hot water and forming clean water discharge containing many bubbles. Can not be.

  On the other hand, when the flow velocity of the air introduced from the air introduction hole is increased, there arises a problem that unpleasant air noise is generated with the flow of air. However, as described above, there is a problem that the size of the air introduction hole cannot be arbitrarily set in order to properly mix air with hot water.

  In the shower head described in JP-A-2006-239106, a double structure in which an air inflow chamber is provided between the main body of the shower head and a water passage through which hot water flows in the main body of the shower head is adopted. ing. In this configuration, outside air is once introduced into the air inflow chamber, and air is introduced from the air inflow chamber into the water passage through the air introduction hole. For this reason, the air sound by the flow of the air flowing into the water passage from the air inflow chamber through the air introduction hole is generated in the main body of the shower head and is difficult to hear outside.

  However, in actuality, it is necessary to take in the same amount of air that flows into the water passage from the air inflow chamber through the air introduction hole into the main body of the shower head from the outside air. Therefore, an air sound is generated in the air introduction hole for introducing air from the outside air into the main body of the shower head, and consequently, an air sound reduction effect cannot be obtained.

  Accordingly, an object of the present invention is to provide a shower device that can reduce the air sound generated with the introduction of outside air while ensuring an appropriate amount of air to be mixed with hot water.

  In order to solve the above-described problems, the present invention provides a shower device that mixes air with hot water supplied from a shower hose and sprinkles water, and is disposed in the shower head body and the shower head body. A water passage forming portion into which hot water supplied from the hose is introduced, and a water spray plate attached to the water passage forming portion and formed with a plurality of water spray holes for discharging hot water introduced into the water passage forming portion; And an orifice portion for restricting a flow path of hot water flowing inside the water passage forming portion, the shower head main body and the shower head main body and the water passage forming portion. A first air introduction hole is provided for introducing air into a space between the second air for introducing air in the space between the shower head body and the water passage forming portion into the water passage forming portion. In hole is provided, the second air introduction holes, the orifice portion is disposed on the downstream side, characterized in that the cross-sectional area being smaller than the first air inlet holes.

  In the present invention configured as described above, the hot water supplied from the shower hose flows into the water passage forming portion, and the flow passage is narrowed by the orifice portion. Air in the space between the shower head body and the water passage forming portion is introduced into the water passage forming portion via the second air introduction hole on the downstream side of the orifice portion. The air introduced from the second air introduction hole is mixed with hot water and discharged from a plurality of water holes provided in the water spray plate. External air is once introduced into the space between the shower head body and the water passage forming portion through the first air introduction hole, and the air in this space enters the water passage formation portion through the second air introduction hole. be introduced.

  According to the present invention configured as described above, an appropriate amount of air can be introduced into the water passage forming portion by setting the cross-sectional area of the second air introduction hole to an appropriate size. Even if the flow velocity of the air flowing through the second air introduction hole is increased and an air sound is generated in the second air introduction hole, the air sound is generated inside the shower head main body. There is no leakage. Further, the same amount of air introduced from the second air introduction hole into the water passage forming portion is introduced from the outside into the space between the shower head main body and the water passage formation portion via the first air introduction hole. However, since the cross-sectional area of the first air introduction hole is larger than that of the second air introduction hole, the flow velocity of the air flowing through the first air introduction hole becomes slow, and a large air noise is generated in the first air introduction hole. Never do. For this reason, according to the shower apparatus of the present invention, it is possible to reduce the air sound generated with the introduction of the outside air while securing an appropriate amount of air to be mixed with the hot water. A plurality of first air introduction holes may be formed. When a plurality of first air introduction holes are formed, the cross-sectional area of the first air introduction holes referred to here is the total cross-sectional area of the plurality of first air introduction holes.

In the present invention, the first air introduction hole is preferably positioned closer to the proximal end side of the shower device to which the shower hose is connected than the second air introduction hole.
In the present invention configured as described above, since the first air introduction hole is positioned on the proximal end side, the first air introduction hole is more than the second air introduction hole when the shower device is hung on a shower hanger or the like. Is also located below. Thereby, the hot water that has flowed back from the second air introduction hole to the space between the shower head main body and the water passage forming portion is drained through the first air introduction hole, so that the hot water does not remain in this space. Further, foreign matters mixed in the space can be washed out and discharged to the outside. On the contrary, if the hot water stays in the space between the shower head main body and the water passage forming portion, the foreign matter in the space enters the water passage forming portion through the second air introduction hole when using the shower device. The problem of clogging the orifice and watering holes occurs. According to the present invention having the above configuration, such a problem can be avoided.

Can be prevented and clogging of the second air introduction hole can be prevented. Thereby, the actual opening area of the second air introduction hole can always be kept appropriate, and the initial air introduction performance can be maintained. In addition, since the orifice part located upstream of the second air introduction hole is also submerged, it prevents foreign matter from adhering to the orifice part when it dries, and clogging of the orifice part having a small channel cross-sectional area. The initial water discharge performance can be maintained.

  In the present invention, preferably, the water retention chamber is formed in a space between the shower head main body and the water flow path forming portion by the water retention chamber communication hole positioned on the distal end side of the shower device with respect to the second air introduction hole. It is communicated.

An air mixing chamber 12b (FIG. 2) is formed on the distal end side of the second orifice receiving recess 12a so as to communicate with the second orifice receiving recess 12a and the flow path expands in a tapered shape toward the distal end. Furthermore, a watering chamber 12c (FIG. 2) is formed on the front end side of the air mixing chamber 12b. The watering chamber 12c has an open front side, and a watering plate 6 is attached to the open portion. Watertightness between the second water flow member 12 and the water spray plate 6 is ensured by packing (not shown).

O-rings (FIG. 3A) are disposed between the ribs 14a and 14b and between the ribs 14c and 14d, respectively. These O-rings ensure watertightness between the first orifice receiving recess 10 c and the orifice forming member 14 and between the two orifice receiving recess 12 a and the orifice forming member 14. A slit-shaped second air introduction hole 20 is formed between the rib 14b and the rib 14c, and the outer peripheral side and the inner peripheral side of the orifice forming member 14 are communicated with each other. Further, a partition wall 22 is provided inside the orifice forming member 14, and a plurality of orifice holes 22a are formed in the partition wall. The second air introduction hole 20 is formed on the downstream side in the immediate vicinity of the partition wall 22, and hot water whose flow velocity is increased through the orifice hole 22 a introduces air from the second air introduction hole 20. . In the present embodiment, the partition wall 22 and the orifice hole 22a constitute an orifice part.

  Further, the space between the rib 14b and the rib 14c forms a water retention chamber 24 together with the first orifice receiving recess 10c and the second orifice receiving recess 12a. As will be described later, when the shower device 1 is not used, hot water is retained in the water retention chamber 24, and the second air introduction hole 20 and the orifice hole 22a provided in the partition wall 22 are submerged. Furthermore, the notch 26 (FIG. 4) is formed in the front-end | tip part of the 1st water flow member 10, When this 1st water flow member 10 and the 2nd water flow member 12 are couple | bonded, this notch 26, A water retention chamber communication hole is formed between the first water flow member 10 and the second water flow member 12. That is, the water retention chamber 24 communicates with the space 4a between the shower head cover 4 and the first water flow member 10 through the notch 26 (water retention chamber communication hole).

  Furthermore, since the orifice forming member 14 is disposed at the joint portion of the first water passage member 10 and the second water passage member 12, the orifice hole 22a is exposed to the outside by dividing the joint portion, and the orifice hole 22a. Maintenance can be performed.

  As shown in FIG. 6, the pressing ring 18 is a ring-shaped member disposed at the lower end portion of the shower head cover 4. A first air introduction hole 28 is formed in the holding ring 18, and a space 4 a between the shower head cover 4 and the first water passage member 10 is communicated with outside air through the first air introduction hole 28. That is, outside air passes through the gap between the pressure ring 18 and the shower hose 2, the first air introduction hole 28, and the gap between the pressure ring 18 and the shower head cover 4, as indicated by an arrow A in FIG. Are configured to communicate with the space 4a. Accordingly, the first air introduction hole 28 is positioned closer to the proximal end side of the shower device 1 than the second air introduction hole 20, that is, the side to which the shower hose 2 of the shower device 1 is connected. Further, the first air introduction hole 28 is disposed at the base end portion of the shower device 1, that is, the portion to which the shower hose 2 of the shower device 1 is connected. In the present embodiment, the shower head cover 4 and the pressing ring 18 constitute a shower head body.

  Further, the cross-sectional area of the first air introduction hole 28 is formed larger than the cross-sectional area of the second air introduction hole 20. In the present embodiment, the cross-sectional area of the first air introduction hole 28 is configured to be approximately twice the cross-sectional area of the second air introduction hole 20. In the present embodiment, one first air introduction hole is formed. However, the number of the first air introduction holes is not necessarily one, and a plurality of first air introduction holes may be formed. When a plurality of first air introduction holes are formed, the first air introduction holes are formed so that the total cross-sectional area of the plurality of first air introduction holes is larger than the cross-sectional area of the second air introduction hole.

  Further, the rotation position of the pressing ring 18 is positioned with respect to the shower head cover 4 by a notch 18 a formed in the pressing ring 18 and a protrusion (not shown) provided on the first water passage member 10. It has become. Thereby, the 1st air introduction hole 28 of the pressing ring 18 is positioned in the front side of the shower head cover 4, ie, the side by which the watering board 6 is arrange | positioned. Therefore, the first air introduction hole 28 is always positioned so as to open toward the front side of the shower head cover 4.

Next, with reference to FIG. 7, the mounting structure of the shower head cover 4 will be described.
As shown in FIG. 7, the male screw 16 a formed on the distal end side of the joint 16 is screwed with a female screw 10 d formed on the proximal end portion of the first water passage member 10, and the joint 16 and the first water passage are formed. Member 10 is joined. Further, the step portion 16 b of the joint 16 is engaged with the concave portion 18 b of the pressing ring 18. Further, four spring arrangement holes 18c (FIG. 6) are provided on the circumference of the pressing ring 18, and a coil spring 30 is arranged in each spring arrangement hole 18c. The distal ends of the coil springs 30 are in contact with the proximal end of the shower head cover 4 and urge the shower head cover 4 toward the distal end side of the shower device 1. On the other hand, the tip of the shower head cover 4 is in contact with the bent portion 6d (FIG. 2) of the perforated plate 6b. With this structure, the shower head cover 4 is pressed against the bent portion 6d by the urging force of the coil spring 30, and the position of the shower head cover 4 is fixed. That is, the shower head cover 4 is fixed by being sandwiched between the bent portion 6 d of the water spray plate 6 and the pressing ring 18.

Next, the operation of the shower device 1 according to the embodiment of the present invention will be described.
First, the hot water supplied from the shower hose 2 reaches the orifice forming member 14 through the joint 16 and the first water passing member 10. Hot water reaching the orifice forming member 14 flows into a plurality of orifice holes 22 a provided in the partition wall 22. The hot water whose flow passage cross-sectional area has been narrowed by the orifice hole 22a has an increased flow velocity, and the pressure of the hot water decreases on the downstream side of the partition wall 22. When the pressure of the hot water is lowered, the air in the space 4a between the shower head cover 4 and the first water passage member 10 is introduced into the water passage through the second air introduction hole 20 by the ejector effect. That is, outside air flows into the space 4 a between the shower head cover 4 and the first water passing member 10 through the first air introduction hole 28 from the gap between the shower head cover 4 and the pressing ring 18. The air in the space 4a flows into the water retention chamber 24 through the water retention chamber communication hole formed by the notch 26, and the air that has flowed into the water retention chamber 24 passes through the second air introduction hole 20 and enters the water passage. To be introduced.

Here, since the first air introduction hole 28 is disposed on the front side of the shower head cover 4, the user may accidentally block the first air introduction hole 28 by gripping the shower device 1. Is unlikely to occur. Moreover, since the 1st air introduction hole 28 is arrange | positioned in the lower end part of the shower apparatus 1, the probability that the 1st air introduction hole 28 will be obstruct | occluded by a user's finger | toe becomes still lower.
The air introduced into the water flow path through the second air introduction hole 20 on the downstream side of the partition wall 22 is sufficiently mixed with hot water in the air mixing chamber 12b whose flow path cross-sectional area is widened toward the downstream side. . The hot water mixed with air flows into the water sprinkling chamber 12c and is discharged as hot water containing bubbles from the watering holes of the plurality of watering nozzles 6a provided in the watering plate 6.

  Further, when air is introduced into the water passage through the second air introduction hole 20, air may be generated due to the small cross-sectional area of the second air introduction hole 20. Is generated inside the shower head cover 4, so that the sound leaking to the outside is very small. Furthermore, when the outside air flows into the space 4a between the shower head cover 4 and the first water passing member 10 through the first air introduction hole 28, the first air introduction hole 28 has a large cross-sectional area. Therefore, the flow rate of air is slow and the generation of air noise can be suppressed. Thereby, the air sound which leaks outside the shower apparatus 1 can be reduced, mixing an appropriate amount of air with the hot water flowing through the water passage.

  Next, when the hot water supplied from the shower hose 2 was stopped and the shower device 1 was hung on the shower hanger 8 attached to the wall surface W as shown in FIG. The hot water is discharged to the outside of the shower device 1 through the first air introduction hole 28. That is, the hot water in the second water passage member 12 flows back into the water retention chamber 24 through the second air introduction hole 20, and the hot water in the water retention chamber 24 passes through the notch 26 (water retention chamber communication hole). It flows into the space 4 a between the shower head cover 4 and the first water passing member 10. The hot water that has flowed into the space 4 a is discharged to the outside of the shower device 1 through the first air introduction hole 28 provided at the base end of the shower device 1. Moreover, in the state hung on the shower hanger 8 shown in FIG. 2, since the 1st water flow member 10 is located in the lowest part of the shower apparatus 1, the hot water in the space 4a does not remain outside the shower apparatus 1 without remaining. Discharged.

  On the other hand, since the notch 26 is located above the second air introduction hole 20 in the state shown in FIG. 2, a part of the hot water in the water retention chamber 24 remains without being discharged. For this reason, in the non-use state of the shower apparatus 1 from which the hot water from the shower hose 2 was stopped, the surface of the hot water in the shower apparatus 1 is generally at the position indicated by the straight line L in FIG. For this reason, the orifice hole 22 a provided in the partition wall 22 is maintained in a submerged state even when the shower apparatus 1 is not in use. When the orifice hole 22a is maintained in a submerged state, the orifice hole 22a can be prevented from being dried, and calcium or the like contained in the hot water can be prevented from accumulating in the orifice hole 22a and clogging the orifice hole 22a.

  According to the shower device of the embodiment of the present invention, an appropriate amount of air is introduced into the air mixing chamber 12b of the second water flow member 12 by setting the cross-sectional area of the second air introduction hole 20 to an appropriate size. be able to. Since the second air introduction hole 20 has a relatively small cross-sectional area, the flow velocity of the air flowing through the second air introduction hole 20 is increased. However, even if an air sound is generated in the second air introduction hole 20, the air sound is displayed in the shower. Since the noise is generated inside the head cover 4, a loud sound does not leak outside. In addition, the same amount of air introduced from the second air introduction hole 20 into the air mixing chamber 12 b passes between the shower head cover 4 and the first water flow member 10 through the first air introduction hole 28 from the outside air. Although introduced into the space 4a, since the cross-sectional area of the first air introduction hole 28 is formed larger than that of the second air introduction hole 20, the flow velocity of the air flowing through the first air introduction hole 28 becomes slow, and the first No loud air noise is generated in the air introduction hole 28. For this reason, according to the shower apparatus 1 of this embodiment, the air sound which generate | occur | produces with introduction | transduction of external air can be reduced, ensuring the appropriate air introduction amount mixed with hot water.

  Moreover, according to the shower apparatus 1 of this embodiment, since the 1st air introduction hole 28 is positioned in the base end side rather than the 2nd air introduction hole 20, when the shower apparatus 1 is hung on the shower hanger 8, The first air introduction hole 28 is located below the second air introduction hole 20. As a result, the hot water that has flowed back from the second air introduction hole 20 into the space 4a between the shower head cover 4 and the first water flow member 10 is drained through the first air introduction hole 28. The foreign matter mixed in the shower head cover 4 can be washed away and discharged to the outside. When the hot water stays in the space inside the shower head cover 4 as in a conventional shower device, foreign matter in the space enters the water passage through the second air introduction hole when using the shower device, The problem of clogging orifices and sprinkling holes occurs. According to the shower apparatus 1 of this embodiment, such a malfunction can be avoided.
