DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
In the present invention, as shown in FIG. 1, the body 1 of the shower head is made of a synthetic resin material, and a plurality of watering plates 3 each having a number of watering holes 4 formed in an annular shape are attached to the head 2 at the tip. The lower part of the body part 5 where the hand is held is a connection part 6 to the hose 7 connected to a faucet fitting (not shown), and hot water is supplied from the hose 7 to the flow path 8 formed in the body part 5. The hot water is discharged from the water spray hole 4 of the water spray plate 3 as shower water.
[0008]
As shown in FIG. 3, the body portion 5 is formed with a cylindrical partition 11 so as to be divided into a primary chamber 9 and a secondary chamber 10 in the middle of the flow path 8, and the partition 11 communicates with the primary chamber 9. The first inlet 12 and the second inlet 13 are provided side by side, and further, the first outlet 14 and the second outlet 15 communicating with the secondary chamber 10 are provided side by side, and are formed by the partition wall 11. A cylindrical loading member 17 is inserted into the through hole 16.
[0009]
The loading member 17 is divided into a first passage 19 and a second passage 20 on the left and right sides in the drawing by a substantially central partition plate 18, and a holding case 26 is formed on the female screw portion 21 formed on the inner peripheral surface of the second passage 20. The male screw portion 27 can be screwed, and a solid tablet 28 such as a fragrance or bathing agent is assembled inside the male screw portion 27.
[0010]
A first valve body 22 capable of opening and closing the first outlet 14, a second valve body 23 capable of opening and closing the second inlet 13, and a third valve body capable of opening and closing the second outlet 15 are provided on the peripheral surface of the loading member 17. 2, and the first valve body 22 closes the first outlet 14 as shown in FIG. 2, the hot water passing through the primary chamber 9 dissolves and mixes the tablets 28 in the second passage 20. While being discharged from the water spray hole 4 of the water spray plate 3 to the outside through the secondary chamber 10, the second valve body 23 closes the second inlet 13 by the operation in the rotation direction of the knob 25 as shown in FIG. When the third valve body 24 closes the second outlet 15, the hot water that has passed through the primary chamber 9 passes through the first passage 19, and the normal hot water that does not mix the tablets is discharged from the watering hole 4 of the watering plate 3 to the outside. Is discharged.
[0011]
As shown in FIG. 1, the peripheral surface of the partition wall 11 is formed with a drainage passage 29 that communicates the second water passage 20 and the outside only during normal water discharge. The drainage channel 29 has residual water in the second passage 20 when the showerhead channel is switched to normal water discharge, and the life of the drainage channel 29 is shortened by dissolving it in contact with the tablet 28 even when not in use. In order to prevent the remaining water from being discharged to the outside, as shown in FIG. 3, as shown in FIG. Is forming.
[0012]
In the above configuration, in order to perform washing with hot water mixed with a tablet in which face washing and hair washing are mixed, the first outlet 14 of the partition wall 11 is closed by the first valve body 22 of the loading member 17 as shown in FIG. Next, when hot water is supplied from the faucet fitting to the hose 7, the hot water flows into the second passage 20 of the loading member 17 from the second inlet 13 of the partition wall 11 and dissolves the tablets 28 such as fragrance and bathing agent. While being mixed with hot water, the water is discharged from the water spray hole 4 of the water spray plate 3 through the second outlet 15 and the secondary chamber 10 of the flow path 8.
[0013]
Next, in order to wash the face and wash with hot water in which the tablet 28 is not mixed, the second inlet 13 of the partition wall 11 is closed by the second valve body 23 of the loading member 17 by the operation of the knob 25 as shown in FIG. When the second outlet 15 is closed by the three-valve body 24 and the primary chamber 9 and the secondary chamber 10 of the flow path 8 are communicated by the first passage 19 of the loading member 17, the hot water contains the second passage 20 containing the tablets 28. The water is discharged from the watering holes 4 of the watering plate 3 without passing through the water.
[0014]
At this time, the flow path of the second passage 20 is blocked from the primary chamber 9 and the secondary chamber 10, and the remaining hot water in contact with the tablets 28 in the second passage 20 passes through the introduction hole 30 to the second. By the introduction of outside air into the passage 20, the water is quickly drained from the drainage channel 29 to the outside.
[0015]
【The invention's effect】
In the first aspect of the present invention, the loading member inserted into the flow path of the main body is mixed with the first passage through which hot water passes by the partition plate and hot water passing through containing tablets such as fragrances and bathing agents. Divided into the second passage, the hot water discharged from the water spray plate by the operation of the knob can be switched to normal hot water that does not mix the tablets that pass through the first passage and hot water that mixes the tablets that pass through the second passage. In the shower head with a tablet, the main body of the shower head has a drain passage communicating with the second passage and the outside, and an introduction hole for introducing outside air into the second passage, and the drain passage and the introduction hole can be opened and closed by the loading member. Since it is communicated with the outside at the time of normal water discharge passing through the first passage and is shut off from the outside at the time of hot water discharge mixed with the tablets passing through the second passage, hot water is passed through the second passage containing the tablets. If there is not, leave the remaining water in the second passage to the outside By discharging, it is possible to prevent the tablet from coming into contact with the remaining water and to prolong the life of the tablet.
[0016]
Further, in claim 2, wherein the loading member has a partition wall for communicating with the second valve body for opening and closing the second inlet of the partition wall, the secondary chamber and the second copies path communicating the primary chamber and the second passage of the flow path A third valve body that opens and closes the second outlet is formed, and the second passage, the primary chamber, and the secondary chamber are closed during normal water discharge by both of the valve bodies.
