Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of draining a bathroom unit having appliances such as a bathtub and a basin, and more particularly to a bathroom unit of a type in which the drainage of these appliances is guided from the side of the trap into the trap under a waterproof pan. It relates to a suitable drain trap.

[0002]

2. Description of the Related Art In general, a reverse-curved drain trap is often used as a drain trap for a bathroom unit. The reason for this is that, because the partition wall is usually removable for the reverse-wound drain trap, the inside of the trap can be easily cleaned by removing the partition wall, and the inside of the drain pipe can be cleaned using a special machine. Is possible.

On the other hand, conventionally, in a bathroom unit having appliances such as a bathtub and a basin (hereinafter simply referred to as appliances), appliance drainage is led to a trap provided in a waterproof pan of the bathroom unit. There are mainly two types of methods.

[0004] One method is to guide the wastewater from the upper surface of the trap into the trap. In this drainage method, the appliance drainage is once drained onto the waterproof pan and led to the trap by the gradient of the waterproof pan, or the drainage from the appliance is led to the trap via the appliance drain pipe.

[0005] Another method is to guide the instrument drainage from the trap side into the trap. In this drainage method, the instrument drainage pipe penetrates the wall of the bathroom unit or the waterproof pan and is connected to the trap side under the waterproof pan, and guides the instrument drainage to the trap via the instrument drainage pipe.

FIGS. 5, 6 and 7 show a conventional reverse-curved drain trap used in these draining methods.

FIG. 5 shows a trap of a type in which the drainage of the tool is guided from the upper surface of the trap into the trap. The drainage of the tool 70a is guided to the trap through the inflow pipe 60.

FIGS. 6 and 7 show a trap of the type in which the tool drainage is guided from the side of the trap into the trap. 6 and 7
Both of the traps have an inflow pipe 60 communicating between the inside and outside of the reservoir 40 on the side surface of the trap. The drainage from the appliance 70a is supplied to the inflow pipe 60 and the opening 5 provided on the side face 40a of the reservoir chamber.
0, and flows into the reservoir 40. Here, when looking at the sealing depth with respect to the washing space 80 and the sealing depth with respect to the appliance space 70, they are as follows. The sealing depth for the washing space 80 is equal to the vertical distance between the reservoir water level 40c and the partition wall dip portion 30a of the partition wall 30. The sealing depth with respect to the appliance side space 70 is equal to the vertical distance between the reservoir water level 40c and the upper end 50a of the opening 50.

In the trap shown in FIG.
And the inner diameter of the inflow pipe 60 are substantially the same, and the upper end of the opening 50a and the partition wall dip portion 30a have the same height in order to make the water depth for the appliance space 70 equal to the water depth for the washing space 80. It is prepared. For this reason, the thickness of the trap of FIG. 6 is increased by about h near the pipe diameter of the inflow pipe 60 as compared with the trap of FIG.

In the trap shown in FIG. 7, the position of the inflow pipe 60 is slightly higher than that in FIG. 6 so as not to increase the thickness of the trap. Therefore, the appliance side space 70
When the height of the upper end 50a of the opening and the height of the partition dip 30a are equalized so that the sealing depth of the opening 50 is equal to the sealing depth of the washing space 80, the area of the opening 50 becomes equal to the opening upper end 50a.
Narrowed and reduced by In addition, regarding the sealing depth described so far, in order to secure the sealing strength of the trap,
Generally, it is 50 mm or more.

[0011]

In the conventional reverse-curved drain trap as described above, when the instrument drainage is guided from the side of the trap into the trap, there are the following problems.

First, in the trap shown in FIG. 6, when a bathroom unit is installed on a building slab in an apartment house or the like, since the clearance between the lower surface of the trap provided on the waterproof pan and the building slab is originally small, the thickness of the trap is small. If it increases, the installation height of the waterproof pan, that is, the bathroom unit floor, must be increased accordingly. As a result, the step between the bathroom unit floor and the dressing room becomes large, and the usability deteriorates. In general, in an apartment house, a pit is provided on an architectural slab or a double-floor structure is used in order to eliminate a step between a bathroom unit floor and a dressing room. However, the bathroom unit using the trap of FIG. Compared to the bathroom unit using the trap of FIG. 5, the pit needs to be extra deepened or the height of the double floor must be increased by the increased thickness of the trap, which leads to an increase in construction cost.

Next, in the trap shown in FIG.
Because the area of the device, that is, the cross-sectional area of the flow path for instrument drainage, decreases,
There is a risk of causing problems such as prolonged drainage time of the equipment. In FIG. 7, the closer the thickness of the trap is to that of FIG. 5, in other words, the higher the inflow pipe 60 is, the smaller the area of the opening 50 is, which further adversely affects the drainage time of the equipment. The thickness of the trap of FIG. 7 cannot be made equal to that of FIG. 5, and the thickness problem described above remains unresolved.

Both of the traps shown in FIGS. 6 and 7 cause a large amount of drainage to be instantaneously discharged from the washing space 80.
The drainage is reflected on the water bottom 20b of the trap body 20,
There is a risk of backflow to the instrument side space 70 via the opening 50 and the inflow pipe 60. The present invention has been made in order to solve the above problems, and an object of the present invention is to provide a bathroom unit having a bathtub, a basin, and other appliances, and to introduce a drainage of the appliance from a trap side surface into the trap. In drain traps, do not increase the thickness of the drain trap, prolong the drainage time of utensils, and prevent reverse drainage to the utensil side even if a large amount of drainage is instantaneously discharged from the washing area. It is to provide a mold drain trap.

[0015]

In order to achieve the above object, according to the present invention, there is provided a water storage chamber, a water storage, and a substantially cylindrical shape which is detachable upward and separates the water from an inflow leg and an outflow leg. And a reverse-curved drain trap having an inflow pipe communicating between the inside and the outside of the reservoir through the opening. Was made into a horizontally long shape, and the vertical distance between the upper end of the opening and the level of the stored water was set to 50 mm or more. For this reason, if the inflow pipe is an instrument drainage pipe, the thickness of the trap does not increase even in the case of a reverse-curved drainage trap in which instrument wastewater is guided into the trap from the side of the trap.

According to a second aspect of the present invention, a shielding member is provided between the inflow leg and the opening, which is separated by the partition, to prevent the flow of water between the two. For this reason, even if a large amount of drainage is instantaneously discharged from the inflow leg side, the water flow of the drainage is prevented by the shielding member, and does not flow back to the appliance side through the opening or the inflow pipe.

According to a third aspect, the shielding member is detachably provided. This facilitates cleaning of the shielding member and the inside of the trap.

According to the present invention, a part of the partition wall also functions as the shielding member. For this reason, the components of the trap can be simplified, and the partition, the shielding member, and the inside of the trap can be easily cleaned.

In the present invention, the area of the opening is equal to or larger than the cross-sectional area of the flow path of the inflow pipe. For this reason,
When the inflow pipe is an instrument drain pipe, there is no decrease in the cross-sectional area of the channel of the instrument drain, and the flow of the drain is not hindered. Therefore, the drainage time of the device is not prolonged.

[0020]
