Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a structure of a suction port for a bathtub, and more specifically,
A suction port body 3 is attached to the wall 2 of the bathtub 1 and has a passage 7 that communicates with the inside and outside of the bathtub 1; A cylindrical body 19 having suction ports 6 provided at intervals in the circumferential direction on its protruding portion, and a suction port cover that closes the opening of the cylindrical body 19 on the bathtub 1 side and is detachably attached to the cylindrical body 19. 20, and a bathtub 1 of the cylindrical body 19 in the inner part of the cylindrical body 19.
This relates to the structure of a bathtub suction port characterized by comprising a filter 4 that is housed inside and can be taken out from a side opening.

The purpose of the present invention is to circulate the hot water in the bathtub with a pump, or to draw the hot water in the bathtub with a pump and use it as a shower. It is easy to collect foreign matter such as hair and dirt, and it is easy to clean the collected foreign matter.
To provide a structure of a suction port for a bathtub that can prevent a bather from recognizing collected hair and dirt and prevent the suction port from being blocked by the bather's body.

The present invention will be explained in detail below with reference to Examples.

In the figure, reference numeral 3 denotes a suction port main body having a passage 7, which is inserted into a hole 8 provided in the wall 2 of the bathtub 1, and a nut 10 is screwed together via a gasket 9. and Natsuto 1
0 and the wall portion 2 is sandwiched between them.

The inner periphery of the opening on the bathtub 1 side of the suction port body 3 is a large diameter portion 12
The opening side end of the large diameter portion 12 is a tapered portion 13 whose diameter gradually increases.

The inner part of the large diameter part 12 is a medium diameter part 15 via a stepped part 14, and the end of the medium diameter part 15 is a contact part 16.

In the figure, reference numeral 17 denotes a tertiary filter, which is fitted into the medium-diameter portion 15, and in the illustrated embodiment is detachably screwed into the filter by means of a screw fastening means 18 consisting of a male thread and a female thread.

The filter block 5 is composed of a cylindrical body 19 and a suction port cover 20 detachably attached to the tip of the cylindrical body 19, and a mesh filter 4 is removably housed inside the cylindrical body 19. It is.

Further, a plurality of suction ports 6 are provided on the outer periphery of the body of the cylindrical body 19.

In the illustrated embodiment, a flange portion 21 is provided protruding from the outer periphery of the suction port cover 20 toward the wall portion 2 side of the bathtub 1.
Furthermore, an annular protrusion 22 is provided protruding inside the flange part 21, and a threaded part 24 at the tip of the cylindrical body 19 is removably screwed into a threaded part 23 provided on the annular protrusion 22.

A locking protrusion 2 is provided on the inner surface of the cylindrical body 19 behind the suction port 6.
5 is provided protrudingly, and the mesh filter 4 has a container shape.
A locking flange piece 26 provided on the opening side of the filter 4 is detachably locked to the locking protrusion 25 to prevent the bather from viewing the filter 4.

In this case, at least the locking collar piece 26 and its root portion may be made of an elastic body so that the locking can be performed elastically using elastic force.

An annular groove 27 is provided on the outer periphery of the rear end of the cylindrical body 19, into which an O-ring 28 is fitted. It is inserted freely.

Here, the tapered portion 13 serves as a guide when the cylindrical body 19 is fitted into the large diameter portion 12.

In addition, when the cylindrical body 19 is detachably attached to the bathtub 1 side opening of the suction port body 3, it may be detachably attached by means of screwing means.

A pipe 29 is connected to the end of the suction port body 3 outside the bathtub 1 .

A pump 30 is disposed in the middle of this piping 29.

In the embodiment shown in FIG.
An example is shown in which the hot water sucked in from the bathtub is returned to the bathtub 1 again.

In the embodiment shown in FIG. 2, the hot water in the bathtub 1 is circulated while being removed by the filter 4, so foreign substances such as hair and dirt mixed in the hot water in the bathtub 1 are removed. The hot water in the bathtub 1 can be cleaned.

In this case, foreign substances in the hot water are mainly removed by the filter 4, but some are also removed by the narrow suction port 6, and further removed by the tertiary filter 17.
This prevents foreign objects such as hair and dirt from getting entangled in the piping 29 and pump 30.

To remove foreign matter trapped in the filter 4 and clean it, remove the filter block 5 and remove the suction port cover 2.
It can be easily cleaned by removing the 0.

FIG. 3 shows another embodiment, in which a shower port 31 is provided at the tip of the pipe 29, and the bathtub 1
The hot water inside is used as shower water.

In this case as well, not only can foreign matter be prevented from getting entangled in the piping 29 or the pump 30, but the shower water discharged from the shower opening 31 will be clean and free from foreign matter.

Of course, in addition to the above-mentioned embodiments, for example, when the hot water in the bathtub 1 is circulated through the piping 29 and discharged into the bathtub 1 again, the structure of the suction port is the same as in the case of a so-called bubble bath in which air bubbles are mixed. It can be of a structure.

As described above, the present invention includes a suction port body that is attached to the wall of the bathtub and has a passage communicating with the inside and outside of the bathtub, and a filter that is detachably attached to the opening of the suction port body on the bathtub side. It consists of an internal filter block and a suction port provided in the body of the filter block, so when hot water is sucked into the bathtub, the filter installed in the suction port prevents hair, dirt, etc. from getting mixed into the hot water in the bathtub. It can remove foreign matter that is trapped in the filter inside the filter block, and it prevents foreign matter from getting entangled in piping or pumps. Furthermore, since the filter block is removable, it is easy to clean the foreign matter that can be caught in the filter inside the filter block. Since the suction port is provided on the body of the block, unlike when the suction port is provided on the front of the filter block, the suction port will not be blocked by the bather's body, and since it is provided on the body of the filter block, the suction port will not be blocked by the body of the bather. It is also possible to install multiple filters around the outer circumference of the bathtub, and as a result, the entire suction port will not be blocked with towels, etc. Furthermore, since they are installed on the wall of the bathtub, they will not interfere with bathing. Since the filter is installed deep inside the bathtub where it cannot be seen with the naked eye, the bather can avoid seeing the hair and dirt collected by the filter, and can bathe without feeling uncomfortable. There are advantages.

Furthermore, since the hair and dirt are collected deep inside, it is possible to prevent the collected hair and dirt from floating out when the suction is not being performed, and there is an advantage that the hot water will not be contaminated.
