Description

  The present invention relates to a bathroom unit.

  The bathroom unit is a bathroom that is completed by assembling unitized members so that it can be completed in a short period of time in a conventional construction method, and has been widely used in recent bathrooms.

  As for the drainage structure in the bathroom unit, it is common to use a drainage trap so that bad odors do not flow backward in the bathroom, and the flow of air is shut off at the sealing part of this drainage trap, from the downstream of the drainage pipe. Prevents odor leaks upstream (in the bathroom).

FIG. 1 shows a drainage structure of a bathroom unit conventionally used, (a) is a plan view of a drain trap, and (b) is a cross-sectional view taken along line DD shown in (a) with a waterproof pan. It is a supplementary note. The waterproof pan 1 is provided with a washing ground drain port 2 and a bathtub drain port 3. The waste water generated in the washing ground flows into the washing ground drain port 2, and the bathtub drainage flows into the bathtub drain port 3.
A drainage trap 4 is connected to the washing ground drainage port 2, and the drainage trap 4 has a sealing wall 5 and a deodorizing cylinder 6 that have a reverse gradient (climbing gradient) toward the downstream where the drainage flows. The sealed water wall 7 and the deodorizing cylinder 6 form a sealed water portion 7.
Further, one end of a drainage elbow 8 is connected to the bathtub drainage port 3, and the other end is connected to the sealing portion 7 of the drainage trap 4.
The sealed water portion 7 stores waste water that could not get over the sealed water wall 5, and the stored waste water blocks off odor so that the odor does not leak into the bathroom unit.

  In recent years, a bathroom unit that can be easily used by elderly people by lowering the height of the bathtub is slightly desired, and a drain trap corresponding to such a bathroom unit has also been proposed. Specifically, it is possible to lower the straddle height of the bathtub by providing a bathtub mounting place lower than the washing place. However, at this time, the bathtub drainage opening becomes lower than the washing ground drainage opening, and therefore, if the drain trap shown in FIG. 1 described above is used, the wastewater generated in the washing ground flows backward into the bathtub. Accordingly, a drain trap as shown in FIG. 2 has been proposed.

  FIG. 2 is a schematic top view and schematic cross-sectional view of a drain trap used in a bathroom unit having a lower tub height. Since the drainage trap used here is provided in a position where the bathtub drainage port 3 is lower than the washing ground drainage port 2 provided in the waterproof pan 1, two drainage traps 9 and 10 are provided. An independent trap is used. Drainage from both traps is connected to one pipe downstream, but it is a separate system until it passes over the sealing wall 5 and also has a sealing part independently. The wastewater that has flowed into the washing ground drain trap 9 from the mouth 2 does not flow backward and does not flow out from the washing ground drainage port 2.

Further, the drain trap shown in FIG. 2 is water-proof, reducing the amount of water sealed in the bathtub drain trap 10 while preventing leakage of odors, in addition to reducing the straddle height of the bathtub and improving user convenience. Lowering the height of the bread 1 is also performed. This lowers the overall height of the bathroom unit by lowering the floor height of the waterproof pan 1, and is particularly important when installed in a high-rise apartment or the like. That is, in high-rise apartments, even if they are the same height, it is possible to create more floors by lowering the height of each floor, so the entire bathroom unit is secured while ensuring the same ceiling height as before. As a drainage trap, the height can be lowered.
JP 2004-278090 A

  However, the drain trap used in FIG. 2 has a big problem that the amount of water sealed in the bathtub drain trap is reduced in order to reduce the floor height of the waterproof pan. That is, when the drainage trap shown in FIG. 2 is used for a high building such as a high-rise apartment, the pressure in the drainage vertical pipe installed in the building during drainage is significantly reduced, and the water in the drainage trap is pulled by the siphon effect. There is a possibility that the sealing water will run out or the amount of sealing water will decrease. And if a water seal runs out, bad smell will be filled in the bathroom unit, and possibility that the problem of giving a pleasant feeling to a user will generate | occur | produce will increase.

  An object of the present invention is to provide a bathroom unit equipped with a drain trap that lowers the straddle height of a bathtub and lowers the floor height of a waterproof pan, and further reduces the possibility of malodor spreading due to running out of sealed water. And

(1) The present invention relates to a washing ground drain trap connected to a washing ground drain outlet and having a sealed water section, and a bathtub drain trap connected to a bathtub drain opening provided at a position lower than the washing ground drain outlet and having a sealing water section; In the bathroom unit, which is connected to the both traps and has a connecting pipe for advancing the drainage that has passed through each sealing part, the sealing part of the bathtub drainage trap is connected from the sealing part of the washing drain trap by connecting the sealing parts. It is a bathroom unit provided with advection piping which carries out drainage advection to a part.
(2) The present invention provides a washing ground drain trap connected to a washing ground drain outlet and having a sealing portion, and a bathtub drain trap connected to a bathtub drain outlet provided at a position lower than the washing ground drain outlet and having a sealing portion; A bathroom unit having a connection pipe connected to the traps and transferring the waste water that has passed through the sealed water parts, wherein the sealed water parts are adjacent to each other via a partition wall, and a through hole is provided in the partition wall. Is a unit.

(5) In any one of items (1) to (4), the height of the connection between the sealing part of the washing ground drain trap and the advection pipe or the height of the through hole is lower than the bathtub drain. Bathroom unit.
(6) The bathroom unit according to any one of items (1) to (5), wherein the bottoms of the washing ground drain trap and the bathtub drain trap have the same height.

According to the present invention, the height of the tub can be lowered by making the bathtub drain outlet lower than the washing ground drain outlet, and the drain trap can be separately provided for the washing ground drain and the bathtub drain. Prevent reverse flow, and even if the tub drain trap temporarily runs out of seal water due to the siphon effect, the advection pipes should drain the water from the wash area drain trap seal to the tub drain trap seal. Therefore, the bad odor does not fill the bathroom unit.
When both sealed water portions are adjacent to each other via a partition wall, drainage advection can be performed by providing a through hole in the partition wall without providing advection piping, and the state of the sealed water outage can be achieved with a simpler structure. It can be prevented from continuing. In addition, when a through hole is provided in the partition wall and a lid is provided in the through hole, a new through hole is provided in the lid, so that it is possible to cope with a lack of water seal, and by removing the lid, the can tool method or the like Can be cleaned. Furthermore, the through-hole provided in the lid can also be used as a removal jig insertion hole when removing the lid, and can make it easier to work in a narrow place.
When the standing wall is provided in the drainage flow path, it is possible to alleviate the drainage of the sealed water portion being pulled due to the siphon effect, and it is possible to make it more difficult for the sealed water to run out.
The bathroom unit provided at a position where the height of the connection between the sealing part of the washing ground drain trap and the advection pipe or the height of the through hole is lower than the bathtub drain port, the drainage flows back through the advection pipe or the through hole. And it can be used more hygienically without entering the bathtub.
When the trap bottom drain trap and the bathtub drain trap bottom have the same height, drainage stored in the wash floor drain trap when the drainage is transferred from the wash floor drain trap to the bathtub drain trap through the advection pipe or through hole. It is possible to prevent not only the bathtub drain trap but also the wash area drain trap from running out of water.

  The washing ground drain used in the present invention drains the waste water generated at the washing ground, and the shape thereof is not particularly limited, and circular, square, or other drain outlets can be used. In addition, an eye plate may be used at the washing place drain outlet so that the drain outlet does not appear directly to the user's eyes.

  The bathtub drain used for this invention drains the water in a bathtub, The shape is not specifically limited, Circular, square, etc. drain outlets can be used. In addition, the bathtub drain is provided at a position lower than the washing ground drain described above, thereby lowering the mounting surface of the bathtub below the washing ground, and as a result when moving from the washing ground to the bathtub. The height across the bathtub can be reduced.

  The drainage trap used in the present invention uses two independent drainage traps, a washing ground drainage trap connected to the washing ground drainage port and a bathtub drainage trap connected to the bathtub drainage port. Has a sealing part. The sealing part should just be what can collect drainage and can block the air flow in the piping. Specifically, use a sealing wall that has a reverse slope toward the downstream (upward slope toward the downstream). Thus, the sealed portion can be formed. Moreover, you may make it arrange | position a deodorizing cylinder directly under a drain outlet.

  The connection pipe used in the present invention is for flowing washroom drainage and bathtub drainage, and merging both drainage downstream from the sealing part of the drain trap and flowing the merged drainage. The connection pipe is not limited to its shape, material, etc., and a commonly used drain pipe can be used.

  The advection pipe used in the present invention connects each sealed water part and performs drainage advection from the sealed part of the wash basin drain trap to the sealed part of the bathtub drain trap, and this advection is performed by natural flow. Is called. In other words, since the bathtub drain is provided at a position lower than the washroom drain, the water level of the sealed water section is also lower in the sealed section of the bathtub drain trap, and as a result, the drainage advection due to natural flow. Is done.

The location of the advection piping must be set below the sealing liquid level. In addition, it is desirable to install as close to the bottom surface of the trap as possible so that sealed water advection can be performed even if the amount of sealed water decreases.
In addition, the diameter of the advection pipe varies depending on the location of both sealed water parts (whether they are adjacent or completely independent and connected by the advection pipe). The diameter of the through hole and the pipe length should be set so that there is no overflow of drainage from the bathtub drainage port and there is no possibility of clogging with dust, dirt, etc. in actual use.

  Since the standing wall used for this invention should just be able to make both sealed water parts independent, a shape etc. are not limited.
