Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a bathtub hot water circulation port fitting that is attached to a bathtub wall when circulating hot water from a hot water circulation heating pot.

[0002]

[Prior art]

 Bathtub hot water is supplied from the hot water heated in the hot water circulation kettle into the bathtub through the hot water supply port of the hot water circulation port fittings attached to the bathtub via piping, and the cooled cold water is returned as hot water. The hot water circulation process of returning from the return hot water port of the circulation port fitting to the pot through another pipe and heating again is repeated. Conventionally, the work of attaching the hot water circulation port fitting to the bathtub requires two pipes. The brazing work is important, and it is necessary to perform both the brazing work of the short tube-shaped mouthpiece to the hot water supply port and the return hot water port of the main body of the circulation port fitting and the brazing work of the tip of each pipe and the rear end of the die. However, brazing requires skill and the brazing work is troublesome and time-consuming.

【Example】

 An embodiment of the present invention is shown in FIGS. The bathtub hot water circulation port fitting of this example includes a net cover 10, a flow distribution plate 20, a flow distribution tube 30, a male tube 40, a tube frame 50, and a circulation port body 60.

The mesh cover 10 filters the return water in the bath 80 through the mesh plate 11 and allows it to flow in. Therefore, the fixed screw 12 is screwed onto the flow distribution plate 20 and cannot be attached to the flow distribution plate 20. It is as close as possible.

The flow distribution plate 20 includes a return hot water outlet 21 for communicating the return hot water that has passed through the mesh cover 10 between the flow dividing cylinder 30 and the male screw cylinder 40, and a hot water supply passage 22 for communicating hot water in the cylinder interior 32 of the flow dividing cylinder 30. And the screw 23 and the screw 34 are screwed together so as to be detachably attached to the flow dividing cylinder 30 and the male screw cylinder 40.

As described above, the flow dividing cylinder 30 has a cylinder outside 31 provided with the return hot water inlet 33 communicating with the return hot water inlet 21 of the flow dividing plate 20 and a cylinder interior 32 communicating with the hot water supply passage 22 of the flow dividing plate 20. And is detachably attached to the flow distribution plate 20.

On the outer surface of the male screw cylinder 40, a male screw 41 to be screwed with a female screw 611 on the inner surface of the outer cylinder 61 of the circulation port main body and a flange portion 42 adapted to be in close contact with the inner wall 81 of the bathtub are provided. The inner surface communicates with the return hot water spout 33 of the diversion tube 30.

The tubular frame 50 covers the flange portion 42 of the male screw tube 40, and is provided with a hot water supply port 51 through which hot water is discharged into the bathtub 80 through the hot water supply passage 22 of the flow distribution plate 20.

The circulation port main body 60 is composed of an outer cylinder 61 and an inner cylinder 62. The outer cylinder 61 has a female screw 611 screwed with the male screw 41 of the male screw cylinder 40, and a flange portion 63 closely attached to the outer wall 82 of the bathtub. A hot water supply cylinder 63 communicating with the hot water supply passage 44 inside the male screw cylinder 40 is provided, an inner cylinder 62 is provided with a return hot water cylinder 64 communicating with the cylinder outside 31 of the flow dividing cylinder 30, and each of the hot water supply cylinder 63 and the return hot water cylinder 64 is provided. Male threads 631 and 641 are threaded on the outer surface of the cylinder. Further, the outer cylinder 61 is provided with a gripping stand 65 for a spanner or a monkey on the outer peripheral surface.

Reference numeral 90 denotes a pipe made of a flexible tube, both ends of which are threaded in the same manner as the male screw 631 of the hot water supply pipe 63 and the male screw 641 of the return hot water pipe 64, and are screwed to these male screws 631 and 641. It has a nut 91. In addition, brazing allowance surfaces 632 and 642 can be provided on the inner surfaces of the hot water supply cylinder 63 and the return hot water cylinder 64 so that a short cylinder for brazing can be inserted and brazed to the inner surfaces of the cylinder.

Another embodiment of the present invention is shown in FIG. The bathtub hot water circulation port fitting of this example has the same configuration as that of the previous embodiment except that the hot water supply pipe 63B and the return hot water pipe 64B of the circulation port main body are both bent, so a detailed description thereof will be omitted.

[0015]

Since the present invention is configured as described above, the hot water supplied from the circulation heating pot (not shown) is supplied from the pipe 90 to the hot water supply pipe 63, the inner pipe 62, the inside 32 of the flow dividing pipe 30, and the flow dividing plate 20. The hot water that has flowed into the bathtub 80 through the hot water supply passage 22 and the hot water supply port 51 of the cylinder frame 50 and becomes cold is used as return hot water for returning the hot water to the return pipe 21 of the flow dividing plate 20, the return hot water outlet 33 of the flow dividing pipe 30, and the flow dividing pipe 30. It goes out to the circulation heating pot (not shown) through the outside of the cylinder 31, the return hot water pipe 64, and another pipe 90.

[0016]

[Effect of device]

 According to the present invention, the male screws 631 and 641 on the outer surface of the hot water supply pipe 63 or the return hot water pipe 64 are screwed at the respective ends of the pipes 90 and 90, respectively. If these nuts 91, 91 are screwed together, they can be immediately connected to the circulation port body 60. At that time, if the gripping stand 65 is held down by a spanner or a monkey, the rotation of the circulation port body 60 can be easily stopped. be able to.

As described above, according to the present invention, even an unskilled worker can easily and quickly perform the work, and because the structure of the circulation mouthpiece main body can be mass-produced by metal or synthetic resin by a die, the production cost can be greatly reduced. You can
