Definitions

  • the present invention relates to a water splash prevention hood, which is to be used in a state where the water splash prevention hood is mounted on a shower head.
  • a hood water splash prevention hood
  • a hood water splash prevention hood
  • a known water splash prevention hood having water drain openings in its wall has the following drawbacks. That is, it is necessary to make the openings large so as to efficiently perform draining of water. On the other hand, when the openings become excessively large, the primary function of the hood (the prevention of splashing of water) is impaired.
  • the present invention has been made in view of the above-mentioned conventional circumstances, and it is an object of the present invention to provide a water splash prevention hood which can enhance both "a water splash preventing effect” and "a water draining effect”.
  • the water splash prevention hood according to the present invention is to be mounted on a shower head having a nozzle for jetting water.
  • the water splash prevention hood comprises: a cylindrical body which is to be connected to the shower head, such that the cylindrical body surrounds a jetting opening of the nozzle; and a plurality of protruding plates, which are formed on an end surface of the cylindrical body and are alternately arranged in a staggered pattern with gaps formed therebetween.
  • the plurality of protruding plates are formed on an end surface of the cylindrical body and are alternately arranged in a staggered pattern with gaps formed therebetween. Thanks to such the configuration, water discharge paths running toward the outside from the inside of the hood are made to meander, where there is no straight path of water jetted to the outside from the inside of the hood. Thus, it is possible to prevent the water from vigorously splashing out to outside. At the same time, the gaps are formed between the protruding plates, and thus it is possible to allow the water to flow out to the outside gently with a sufficient flow rate by properly setting size of the gap.
  • FIGs. 1A and 1B are perspective views of a water splash prevention hood 1 according to one embodiment of the present invention, in a state where the water splash prevention hood 1 is mounted on a shower head 2.
  • Fig. 1A is the perspective view from a lower side
  • Fig. 1B is the perspective view from an upper side.
  • Fig. 2A is a bottom plan view showing only the shower head 2 from just below, and Fig. 2B shows a state where the water splash prevention hood 1 is mounted on the shower head 2.
  • the shower head 2 includes a large number of projections 3, and jetting openings 4 are formed between the projections 3.
  • the jetting openings 4 communicate with a nozzle disposed in the shower head 2, and a water flow which passes through the nozzle jets from the jetting openings 4.
  • the projections 3 are provided for enhancing a massaging effect on the scalp by coming into contact with the scalp.
  • the projections 3 are not indispensable elements in the present invention. That is, the water splash prevention hood 1 of the present invention can be used with a shower head having no such the projections 3.
  • Fig. 3 is a perspective view showing only the water splash prevention hood 1 in Fig. 1 .
  • Fig. 4 is a bottom plan view of the water splash prevention hood 1 from just below.
  • the water splash prevention hood 1 includes a cylindrical body 10 which is to be connected to the shower head, and a plurality of protruding plates 20, 30 formed on an end surface 11 of the cylindrical body.
  • the cylindrical body 10 of the water splash prevention hood 1 is to be connected to the shower head 2, such that the cylindrical body 10 surrounds all jetting openings 4 from the outside.
  • the plurality of protruding plates 20, 30 are positioned on two imaginary concentric circles "X” and "Y” having different diameters.
  • the protruding plates positioned on the inner concentric circle “X” are referred to as “inner protruding plate 20”
  • the protruding plates positioned on the outer concentric circle “Y” are referred to as “outer protruding plate 30”.
  • the inner protruding plates 20 and the outer protruding plates 30 are alternately arranged in a staggered pattern with gaps formed therebetween, and flow passage "L" is formed in a gap between the protruding plates.
  • the water jetted from the jetting openings 4 of the shower head 2 is temporarily retained in a space surrounded by the hood 1 and a scalp, and thereafter the water flows out to the outside through the flow passages "L".
  • the shape of the flow passage "L” realized by the arrangement of the protruding plates 20, 30 unique to the present invention, it is possible to prevent water from vigorously splashing out toward the surroundings, and at the same time the water flows out to the outside gently. This principle is described hereinafter.
  • Fig. 5A is a partially enlarged view of a bottom surface of the water splash prevention hood 1 shown in Fig. 4 , wherein two outer protruding plates 30 and one inner protruding plate 20 are shown.
  • Fig. 5B shows that region viewed laterally from a side of the water splash prevention hood 1.
  • the inner protruding plate 20 at the center is depicted as being slightly higher than the outer protruding plates 30 on both sides of the inner protruding plate 20.
  • all protruding plates 20, 30 have the same height.
  • the width "K" of the inner protruding plate 20 is set larger than the distance "J" between two adjacent outer protruding plates 30, and the inner protruding plate 20 extends over the entire width of the distance "J” between two outer protruding plates 30, in a circumferential direction. That is, when viewed laterally from a side of the hood 1, the other side of the plates 20, 30 cannot be seen, being interrupted by the plates 20, 30 themselves. In other words, there is no flow passage which runs straightly in a radial direction of the cylindrical body 10, and only the flow passage "L” which meanders as shown in Fig. 5A exists.
  • Fig. 5C shows a modification to the embodiment shown in Fig. 5B .
  • an inner protruding plate 20 does not extend over the entire width of the distance "J" between the adjacent two outer protruding plates 30, and there exists a gap "Q". That is, there is a flow passage which extends straightly in a radial direction, passing through the gap "Q".
  • the modification may be somewhat inferior to the embodiment shown in Fig. 5B .
  • the advantageous effect can be sufficiently obtained, provided that the size of the gap "Q" is small.
  • the protruding plates 20, 30 be arranged as shown in Fig. 5B over the entire circumference of the cylindrical body 10.
  • the arrangement shown in Fig. 5B is provided at least one on a circumferential wall of the cylindrical body 10, such the advantageous effect can be obtained to some extent. The more the arrangements are increased, the more such the advantageous effect would be enhanced.
  • the arrangement of the inner protruding plates 20 is considered as an "inner row”
  • the arrangement of the outer protruding plates 30 is considered as an "outer row”.
  • the "inner row” and the “outer row” could be two circles having the centers at different points, or otherwise the “inner row” and the “outer row” could be in other shaped rows, other than circles.
  • the circle “X” corresponds to the "inner row”
  • the circle “Y” corresponds to the "outer row”.
  • the plurality of protruding plates 20, 30 belong to clear "two rows”. It is sufficient that the plurality of protruding plates 20, 30 be alternately arranged in a staggered pattern such that gaps are formed therebetween.
  • cylindrical body 10 Any convenient shapes of the cylindrical body 10 could be employed, in accordance with the shape of the shower head.
  • the cylindrical body 10 could have a quadrangular cylindrical shape, or an elliptical cylindrical shape, other than the circular cylindrical shape.
