Description

  The present invention relates to a water receiving structure for a pipe connecting portion of a bathtub, and more particularly, to a water receiving structure for preventing water leaking from a pipe connecting portion provided on a side wall of a bathtub from falling on a building frame.

  Conventionally, in a unit bath of a so-called washroom-integrated bathtub that does not have a waterproof structure such as a waterproof pan between the bathtub and the building frame, a reheating pipe is passed through a hole provided in the bathtub side wall to the bathtub side wall. It was sometimes installed. In this way, when the reheating pipe is provided on the side wall of the bathtub of the unit bath, there is a risk of water leakage from the pipe connection portion. If water leaks in this way and flows down into the building frame, the building frame may be damaged. As a technique for preventing such a situation, a water receiving pan that receives water leakage from the pipe connecting portion and a water receiving box that covers the pipe connecting portion are disclosed.

  For example, in Patent Document 1, a water receiving pan is disposed below a pipe connecting portion provided through a side wall of a bathtub to receive water that leaks and falls from the pipe connecting portion. A water receiving structure is described in which water scattering prevention walls are provided on the outer surface of the side wall of the bathtub on both sides of the section, and water scattered from both sides of the pipe connection part is stopped by the water scattering prevention walls and received by the water receiving pan. ing.

  In addition, Patent Document 2 discloses that an opening for passing a drainage pipe and a reheating pipe are passed through in order to prevent water splashing from the pipe connection part and water from the pipe connection part from being transferred to the building frame. The example which covered the pipe connection part with the water receiving box which provided opening of this is described.

  However, in the technique of Patent Document 1, water that leaks from the pipe connection portion and directly falls can be stopped and received by the water pan, but water that scatters from the pipe connection portion, particularly in the direction opposite to the bathtub. There was a problem of not being able to receive the water.

  On the other hand, in the technique of patent document 2, since the pipe connection part is entirely covered with the water receiving box, it can respond to the water scattered from the pipe connection part. However, since the water receiving box of Patent Document 2 entirely covers the pipe connecting portion, the water receiving box is temporarily removed from the bathtub side wall in order to install the pipe connecting portion and check the leakage state. It was necessary to remove and refit. However, the bathtub side wall to which the pipe is attached is generally covered with the wall of the unit structure of the unit-type bus, and the space between the building frame and the pipe connection portion is extremely narrow. Therefore, it is not easy to remove and reattach the water receiving box in such an installation state. In particular, when checking the leakage status of pipe connections, it is necessary to remove and check the water receiving box. However, since it is difficult to see the inside of the water receiving box, the water leaked when removing the water receiving box May fall into the building frame. That is, in the water receiving box of this patent document 2, there was a difficulty in the maintenance work of a pipe connection part.

  The present invention has been made in view of such circumstances, and its purpose is to prevent water splashing from the pipe connection part from falling onto the building frame, and to attach the pipe connection part and An object of the present invention is to provide a water receiving structure for a pipe connecting portion of a bathtub that can secure a space for maintenance work without any trouble.
