Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a roll-up bathtub lid device incorporating a bathtub cleaning nozzle and pipe.

(Prior art and its problems) For the purpose of automating the cleaning of bathtubs, a method has become widespread in which a nozzle is provided on the bathtub lid and cleaning substances such as detergent and washing water are sprayed from the nozzle to clean the bathtub. However, in this method, the pipe used as the supply path for the cleaning substance was simply routed around the bathtub lid. There were problems in that the pipe and the lid would come apart or the pipe would get tangled with the lid, making it extremely difficult to handle.

The present invention solves these problems.

(Means for Solving the Problems) The present invention will be explained based on FIGS. 1 to 4, which correspond to embodiments. First, as shown in FIG. A pipe 3 for supplying a cleaning substance to a provided nozzle 2 for cleaning the bathtub is arranged inside the roll-up bathtub lid 1.
Furthermore, when arranging the pipe 3, as shown in FIG. The pipe 3 is constructed so that it can freely slide within the pipe 4.

This structure reduces the bending stress applied to the pipe 3 due to the reduction or expansion of the dimension between the elements 4 in the upper part of the bathtub cover 1 that occurs when the bathtub cover 1 is rolled up or unrolled. This is to facilitate the winding and unwinding operations of the bathtub lid 1 and to prevent bending of the pipe 3, and the radius of curvature of the meandering may be configured as appropriate as long as such effects can be achieved.

Further, the pipe 3 may be made of vinyl chloride, polyethylene, or the like as long as it has appropriate flexibility and can absorb the bending stress applied to the pipe 3 when the bathtub lid 1 is rolled up or unrolled.

(Function) With the above configuration, the pipe 3
can be stored in the roll-up type bathtub lid 1, and the pipe 3 is arranged in a meandering manner, and the pipe 3 is configured to be able to slide freely in the holding part of the pipe 3, so that the roll-up of the bathtub lid 1 is prevented. , the bending stress applied to the pipe 3 during unwinding can be reduced.

(Effects of the invention) As described above, in the present invention, in a roll-up bathtub lid equipped with a bathtub cleaning nozzle, a pipe for supplying a cleaning substance to the nozzle is disposed inside the bathtub lid. This eliminates the difficulty of handling when the pipe and bathtub lid come apart when the pipe is rolled up or unwound, or when the pipe gets entangled with the bathtub lid. In addition, the pipes are arranged so that they meander in the direction of wrapping and unrolling the bathtub lid, and the pipes are configured to be able to slide freely in the pipe holding section, so the tub lid can be rolled up and unrolled. Since the bending stress applied to the pipe during unwinding can be reduced, winding and unwinding operations become easier, and bending and breakage of the pipe can be prevented.
