[Problems to be solved by the invention]
In the case of the above conventional example, a hole for passing a pipe such as a water supply pipe or a hot water supply pipe is opened on the wall surface of the bathroom, and a pipe joint is attached upward in this hole and piped through this pipe joint. According to this, for example, a plurality of holes are made in a wall or a pipe joint is attached to each hole in an upward direction. This type of work takes time and effort, and the work efficiency does not increase. It was.
By the way, in the case of this type of piping structure in which piping is performed through the wall surface of the bathroom, if the projecting dimension of the pipe to the back of the wall (see D in FIG. 1) increases, the wall thickness is increased and the bathroom space is reduced. It will be. For this reason, conventionally, in this type of piping structure, elbows (pipe joints that change the direction of the pipe line by 90 degrees) are often used because it is necessary to reduce the dimension D and perform piping. Thus, when an elbow is used, the direction of the hot water is changed at the elbow, and pressure loss is likely to occur. Also, the elbow is attached to the upper end of the rising pipe behind the wall. There was a problem that the degree of freedom in construction was lost, making construction difficult.
[0005]
The present invention has been proposed in view of such conventional situations.
Therefore, the technical problem of the present invention is that the piping work can be simplified, speeded up and reduced in cost, without using an elbow that tends to cause pressure loss, and the projecting dimension of the pipe to the back of the wall is increased. An object of the present invention is to provide a bathroom piping structure that can be formed without piping.
[0006]
[Means for Solving the Problems]
The present invention employs the following technical means in order to solve the above problems.
[0007]
That is, as shown in FIG. 1 and the like, the present invention is a bathroom piping structure that is piped to bathroom facilities via a bathroom wall 1, and a plurality of pipes 4 are passed through the wall 1. An opening 5 is formed, the opening 5 is closed by a lid 8 projecting into the bathroom, and an inclined surface portion 8a having an inclined surface directed inward of the bathroom is formed on the lid 8. The inclined surface portion 8a An attachment hole 8a 1 for attaching the pipe joint 10 is formed in the pipe, and the pipe joint 10 is previously attached to the inclined surface portion 8a via the attachment hole 8a 1. The O-ring 10a is provided, and the pipe 4 is attached to the pipe joint 10 in a water-tight manner by the O-ring 10a and connected to the equipment in the bathroom (Claim 1).
[0008]
Here, as the facilities in the bathroom, there are a faucet 2 for water supply or hot water supply, or a bathtub 3 with a reheating function. Therefore, the pipe 4 includes a water supply pipe connected to the water tap, a hot water supply pipe connected to the hot water tap, or a hot water forward pipe and a return pipe connected to the bathtub 3 with a reheating function. Examples of the tube 4 include a flexible metal tube such as a copper tube in addition to a resin-made flexible tube. In the case of the present invention, the opening 5 is usually formed in a square shape such as a square, but the shape is arbitrary. In addition, here, the lid 8 protruding into the bathroom means that the lid 8 is formed to be recessed in the bathroom side so that the pipe 4 can be easily drawn into the bathroom without using an elbow. Specifically, it is realized by forming the lid 8 into a vertical cross-sectional hat shape, a vertical cross-sectional triangle shape (see FIGS. 8 and 9), or the like. In the case of the present invention, if the inclined surface portion 8a has a space where the inclined surface is directed inward of the bathroom and piping is possible, the formation position, size, and gradient are arbitrary.
[0009]
In the case of the present invention , the tube 4 can be stably attached to the inclined surface portion 8a . The tube joint 10, since a through fitting of the type for inserting the tube 4, the construction is simplified, water leakage does not Rukoto occur at joint points.
[0010]
In the present invention, the inclined surface portion 8a is preferably formed on the upper portion of the lid 8 (Claim 2 ).
[0011]
This is because according to this, the pipe 4 can be connected to the deck-type faucet 2 provided on the flange surface of the bathtub 3 by linearly extending from the inclined surface portion 8a, and piping can be performed with a small pressure loss.
[0012]
In the present invention, the inclined surface portion 8a may be formed on the side portion of the lid 8 (claim 3 ).
[0013]
This is because it is possible to cope with the case where piping can only be made from the lateral direction due to reforming or the like.
[0014]
Moreover, it is preferable that this invention is formed in the wall surface position which the opening part 5 conceals with the bathtub 3, and opposes the side wall of the bathtub 3. (Claim 4 ).
[0015]
This is because the opening 5 can be prevented from being exposed and the beauty of the bathroom is not harmed.
[0016]
