Description

  The present invention relates to a suction port structure mounted on a bathtub body in a jet tub.

  In a jet tub, a massage effect and a relaxation effect are promoted by jetting bath water mixed with bubbles and causing the bath water to flow vigorously (see, for example, Patent Document 1).

As an example of such a jet tub, the outline is shown in FIGS.
In FIG. 10, 80 is a bathtub. 10A is a plurality of outlets provided in the bathtub side wall 81, 10B is one inlet provided in the bathtub side wall 81, 90 is a circulating pressure pump installed outside the bathtub, as shown in FIG. The suction port 10B is connected to the suction side of the pump 90 by a pipe 91 such as a flanged elbow, and the discharge side of the pump 90 is connected to the jet port 10A by a pipe 92.

  Thus, when the pump 90 is driven, bath water is ejected by the discharge pressure of the pump 90 and air is sucked from an air suction port (not shown) along with the flow of the bath water so that a bubble bath water jet is ejected from the ejection nozzle. On the other hand, the bath water is sucked from the suction port 10B by the suction pressure of the pump 90.

In the jet tub, it is indispensable to remove the hair at the inlet 10B in order to prevent the hair mixed in the bath water in the bathtub 80 from being caught in the impeller of the pump 90 through the inlet 10B. .
Therefore, in order to eliminate such a risk, the present applicant has proposed to attach a decorative cover with a small hole incorporating a mesh cover to the suction port of the jet tub.

In the above inlet structure, when bath water is inhaled through a small hole in the decorative cover, the hair is captured by the mesh cover so that it does not reach the pump. Failure due to winding can be avoided.
Japanese Patent No. 3038885 (FIGS. 1 and 2)

  By the way, the decorative cover in the suction port structure is screwed and attached to the tip of the suction port protruding to the inner surface side of the bathtub side wall, and in normal use, the decorative cover loosens and comes off. Although it is not, it may be used with the makeup cover removed due to children's play. Therefore, there is a danger of diving into the bath water while taking a bath as it is, or in elderly people, if the body is taken and slipped and the head is submerged in the bath water, the head will be drawn into the bath water and cause personal injury There is.

  An object of the present invention is to provide a suction port structure for a jet tub in which a decorative cover having a suction hole cannot be easily removed from the suction port of the jet tub.
