Description

  The present invention relates to a shower head.

  The shower head has an annular shower water or two water passages through which water flows, and a number of shower water spray holes provided in the first water passage of the shower head The shower water forms an annular or substantially annular curtain shower in which the diameter of the shower head is larger than the outer diameter of the user's head, and the center of the water passage from the many shower water jet holes provided in the second water passage There has already been proposed a shower apparatus in which shower water is jetted in the axial direction (see, for example, Patent Document 1).

That is, in the case of this shower device, the curtain-shaped shower that is formed in an annular shape by the spray shower water sprayed from the shower water spray hole of the first water passage is formed in a water film shape. A warm atmosphere is maintained by the heat of the shower water, and even in the winter, the body can be sufficiently warmed only with the shower water, and the body can be washed without getting the head wet.
Further, since shower water is jetted from a large number of shower water injection holes provided in the second water passage toward the central axis of the water passage, shower water is allowed to flow into the second water passage. By doing so, it is possible to wash the head and body with both hands without having to hold the shower head by hand as in a conventional shower device.

However, in the case of the shower device described above, since the shower water sprayed from the shower water spray hole of the second water passage is spread radially, the shower water directly hitting the user is dispersed. Therefore, it is inefficient to use for shampooing and the like and has a poor feeling of use.
In addition, the shower apparatus main body provided with the first water flow path and the second water flow path is supported by a slide bar or the like, and the shower apparatus main body is moved up and down along the slide bar so that even users with different heights can efficiently perform the operation. Although it is possible to perform hair washing, etc., the shower device main body has a large diameter, so it must have a support structure that can withstand a considerable load in order to hang it up and down with the hand. There is a problem of cost.

  Therefore, in order to solve this problem, the inventors of the present invention have two water passages through which water or water for shower having a ring shape or a substantially ring shape is passed, and provided in the first water passage. A large number of shower water sprayed from a large number of shower water spray holes formed to form a circular or substantially annular curtain shower having a diameter larger than the outer diameter of the user's head, and to the second water passage A shower head in which shower water is jetted from a large number of provided shower water injection holes toward the central axis of the water flow path, and is showered from a large number of shower water injection holes provided in the second water flow path. In addition to spraying water in a linear shape, some of the shower water spray holes out of the large number of shower water spray holes gather by the jetted shower water colliding at the first virtual assembly point. like The remaining shower water injection holes are formed in the wall surface of the second water passage at an injection angle, and at least some of the remaining shower water injection holes are higher than the first virtual collection point. There has already been proposed a shower apparatus provided with a shower head that is perforated on the wall surface of the second water passage at an injection angle so as to collide and gather at second virtual meeting points having different positions (Japanese Patent Application No. 2005). -147812).

That is, according to the shower apparatus, the shower water injected from the second water passage gathers at least at two locations where the heights of the first virtual gathering point and the second virtual gathering point are different, resulting in a thick flow. Fall. Therefore, even if the shower apparatus main body is not moved up and down, users with different heights can comfortably perform hair washing and the like efficiently.
By the way, although the shower head of the shower apparatus is usually formed of a resin molded product, as described above, if it is attempted to obtain a shower head having shower water injection holes with different angles as one molded product, the injection angle There is a problem that it is necessary to release the mold at a different angle every time, and the mold structure is complicated.

  Thus, the inventors of the present invention have a shower head having a groove-like recess serving as a shower water passage, and a shower water injection hole forming groove having a different angle is formed in the side wall surface of the groove-like recess. A shower head body, a lid member that fits into the opening entrance of the groove-shaped recess, closes the opening of the groove-shaped recess, and the lid side wall surface watertightly closes the opening of the shower water injection hole forming groove I thought to make it with a plurality of members.

  However, when the shower head is structured as described above, the structure of the molding die is simplified, but it is necessary to form the groove portions of the shower water injection hole forming grooves having different angles. Therefore, when water is discharged at several angles from a water discharge part arranged on one circumference or a straight line, the shape of the fitting surface (water stop surface) of each part becomes complicated, water stop is difficult, and assembly is easy. There is a problem.
