Hereinafter, the embodiment which actualized the shower head of the present invention is described in detail.
As shown in FIGS. 1 and 4, the shower head 10 of the present embodiment includes a shower head body 13 having a grip portion 11 and a flow path 12 through which hot water is circulated, and a tip of the shower head body 13. And a water discharge port 14 provided in the section. A water stop button 15 is provided on the side of the shower head main body 13 so as to penetrate the shower head main body 13, and the flow stop 12 is blocked by pressing the water stop button 15 in one direction. The channel 12 is opened by pressing in the opposite direction. The water discharge port portion 14 includes a communication passage 16 that communicates with the flow path 12 of the shower head body 13 and a water discharge face portion 17 that communicates with the communication passage 16 and can take a plurality of water discharge forms. is doing. A water discharge nozzle 18 for discharging hot water to the outside is provided at the center of the water discharge face portion 17.

  The communication path 16 is divided into a first communication path 16a positioned at the center of the water discharge port 14, a second communication path 16b positioned on the outer periphery thereof, and a third communication path 16c positioned further on the outer periphery thereof. Thus, any one of the communication passages 16 a, 16 b, 16 c is configured to communicate with the flow path 12 of the shower head body 13. The switching mechanism 19 is switched by rotating an operation knob 21 of an operation ring 20 that is rotatably provided on the outer periphery of the water discharge face portion 17.

  That is, the switching mechanism 19 includes a spherical valve body 23 housed in the valve body housing chamber 22, a coil spring 24 that biases the valve body 23 forward (to the left in FIG. 1), and movement of the valve body 23. The engagement member 25 is formed integrally with the operation ring 20 that restricts or releases the operation. Then, by rotating the operating ring 20, the engaging member 25 formed integrally with the operating ring 20 is rotated, and the valve body 23 is moved against the urging force of the coil spring 24 or released. By doing so, the hot water flow path is switched.

  The water discharge nozzle 18 is provided in a protruding portion 26 that protrudes forward at the center position of the water discharge face portion 17, and includes a hemispherical concave portion 27 on the inner surface side of the water discharge face portion 17 and a horizontally long lip-shaped concave portion 28 on the outer surface side. ing. The horizontally long lip-shaped recess 28 is a horizontal surface 29 having a lower surface formed substantially horizontally, and an inclined surface (curved surface) 30 that is inclined obliquely upward so that the upper surface becomes higher toward the outer surface side to determine a predetermined water discharge angle. ing. A horizontally long lip-shaped recess 28 intersects and communicates with substantially the upper half of the hemispherical recess 27. Therefore, the hot water reaching the hemispherical concave portion 27 is discharged obliquely upward in a state of being expanded in the lateral direction by the horizontally long lip-shaped concave portion 28. The front face of the water discharge face portion 17 is provided with a notch portion 31 formed in a front laterally long shape, and the horizontally long lip-shaped recess 28 is opened in the notch portion 31.

  Then, the hot water from the first communication passage 16a reaches the water discharge nozzle 18 and is discharged forward from the hemispherical concave portion 27 through the horizontally long lip-shaped concave portion 28 to form a fan-shaped water discharge 32 (see FIG. 5) having a front fan shape. It is supposed to be. That is, the water discharge angle θ by the water discharge nozzle 18 is set such that the water discharge direction is directed from the tip of the shower head body 13 to the extension direction (upward direction) y rather than the axial direction x of the water discharge port portion 14. Here, the water discharge angle θ means an angle formed by the central portion of the hot water discharged from the water discharge nozzle 18 with respect to the axial direction x of the water discharge port portion 14. Water discharged from the water discharge nozzle 18 is formed with a constant width around the central portion of the hot water (the range of the two-dot chain line shown in FIG. 1). As shown by the two-dot chain line in FIG. 1, the hot water discharged from the water discharge nozzle 18 tends to scatter to the surroundings when it is separated from the water discharge nozzle 18 by a certain distance. Thus, by setting the water discharge angle θ upward from the horizontal direction, when cleaning the wall surface 34 of the bathroom 33, the joint 35 or the upper region 37 of the corner portion 36, the work can be easily performed without almost bending the wrist 38. It can be carried out.

  Specifically, the water discharge angle θ is preferably 5 to 60 °, and more preferably 10 to 30 °. When the water discharge angle θ is smaller than 5 °, the water discharge direction is close to the axial direction x of the water discharge port 14, and the wrist 33 is cleaned when cleaning the wall surface 34 of the bathroom 33, the joint 35, or the upper region 37 of the corner portion 36. It is necessary to bend 38 and turn the palm 39 upward, which is not preferable because the operation becomes troublesome. On the other hand, when it is larger than 60 °, it is necessary to bend the wrist 38 greatly downward when cleaning the wall surface 34 of the bathroom 33, the joint 35 or the lower region 41 of the corner portion 36, and the operation is rather troublesome. Results.

  As shown in FIG. 1 to FIG. 3, a large number of water discharge holes 43 are formed through the front annular region at the outer peripheral position from the water discharge nozzle 18 of the water discharge face portion 17 to form a May rainy water discharge. ing. A large number of water spray holes 44 are formed in a front annular region in the outer peripheral position from the water discharge hole 43 of the water discharge face portion 17 so as to form mist-like water discharge. And it is comprised by the operation knob 21 of the said switching mechanism 19 so that it can switch to rod-shaped (fan-shaped), May rainy, or drizzle-like water discharge.

  A reference mark 45 for confirming the rotational position of the operation ring 20 is provided at the upper end of the water discharge face portion 17, while a bar-shaped water discharge mark 46 indicating the water discharge state from the water discharge nozzle 18 is provided on the operation ring 20. In addition, a mark 47 for May rainy water discharge from the water discharge hole 43 and a mark 48 for drizzle water discharge from the water spray hole 44 are provided. When the operation dial 21 is located at the lowermost position, the bar-shaped water discharge mark 46 faces the reference mark 45, and is rotated about 45 ° counterclockwise from the position at the water discharge face portion 17 shown in FIG. In this case, the mark 47 of the May rainy water discharge is opposed to the reference mark 45. Further, when the lens is rotated about 45 ° in the clockwise direction in FIG. 3, the mark 48 of drizzle water discharge is opposed to the reference mark 45.

Next, the effect | action is demonstrated about the shower head 10 of this embodiment.
Now, as shown in FIG. 5, when the shower head 10 is used in the bathroom 33, the grip portion 11 of the shower head body 13 is gripped with the right hand or the left hand and is provided on the outer periphery of the water discharge face portion 17. The operation ring 20 is rotated and set so that the marks 46 to 48 indicating a desired water discharge form are opposed to the reference mark 45. For example, the operation ring 20 is rotated from the lowermost position by about 45 ° counterclockwise in FIG. 3 so that the mark 47 of the May rainy water discharge is set to face the reference mark 45, and water is discharged in that state. You can wash your body with May rainy water and rinse your shampooed hair.

  Thereafter, when the wall surface 34, joint 35 or corner portion 36 of the bathroom 33 is cleaned (washed) by the shower head 10, the operation ring 20 is positioned at the lowermost position, and the bar-shaped water discharge mark 46 faces the reference mark 45. Set to (cleaning mode). As shown in FIG. 5, the hot water from the first communication passage 16 a in this state flows from the hemispherical recess 27 to the horizontally long lip-shaped recess 28 by the water discharge nozzle 18, and from the horizontally long lip-shaped recess 28 to the fan-shaped water discharge 32. Water is discharged toward the front wall surface 34, joint 35, or corner portion 36. At this time, since the water discharge direction is set above the axial direction x of the water discharge port 14, when cleaning the wall surface 34, joint 35 or the upper region 37 of the corner portion 36, Work can be performed smoothly without changing. In addition, when cleaning the wall surface 34 of the bathroom 33, the joint 35, or the lower area | region 41 in the corner part 36, it can carry out easily by turning the hand holding the shower head main body 13 a little downward.
