Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a drainage device for a bathtub, and more particularly to a drainage device for a bathtub of the type in which two bathtubs are integrally connected and each bathtub has its own drain port.

Conventionally, various structures have been known as drainage devices for aquariums, and a representative example is the one disclosed in Japanese Utility Model Application No. 51-51158M, which has two drainage holes and a σA-bar flow hole. water is drained from one collection trap, so if water from two aquariums is drained at the same time, the mountain water tanks will be connected at the collection trap part, especially if the water levels of the mountain water tanks are different, the high water level Water from the tank may flow into the tank at a lower water level, contaminating the tank at a lower water level. Also, since the water from all the tanks flows into one collecting trap, it is easy to get clogged, and the drainage capacity is extremely reduced.If one tank is empty, the waste water from the other tank will flow into the empty tank. This may contaminate the inside of the empty aquarium.

It is an object of the present invention to solve the above-mentioned problems and to prevent water drained from one bathtub from flowing into the other bathtub, thereby preventing the bathtub from becoming dirty.

The basic structure of the present invention is to prevent the two bathtubs from communicating with each other on the drain side by providing traps corresponding to the drain ports of two adjacent bathtubs.

Hereinafter, the present invention will be explained in detail based on illustrated embodiments.

The drawing shows a tank as an example of a water tank.

In the figure, (A>) is the bathtub body, and two bathtubs (1) and (2) are connected to each other in one direction.For example, the bathtub (1) is used for bathing, and the water tank (2) is used for washing the body or Although it is used for hot water, it is not limited to this usage example.

The two bathtubs (1) and (2) each have drain ports (3) and (4) at the bottom.
), and the upper ends of the adjacent side walls (1a) and (2a) are connected via a common upper edge surface (5), and an upper edge surface (5) is provided between the side walls (1a) and (2a).
) A space (6) is formed below.

Above, the common upper edge surface (5→ is slightly lower than the top surface of bathtubs (1) □ (2), A notch-shaped recess (7) is provided, and an overflow hole (8) is bored in the center of the bottom of the recess (7), and this bottom is connected to the overflow from the respective bathtubs (1) and (2). It is tilted downward toward one hole (8).

(9) is the lid of the recess (7), which is formed into a roughly mouth-shaped cross section;
The locking steps (1) provided on the walls of both lengthwise ends of the recess (7)
Fit and lock both ends to 0) and cover the recess (7).

The lid (9) is designed so that its lower end has a clearance (11) between it and the bottom of the recess (7), and also has a locking step (10).
) can be secured to the lid (9) using a suitable fixing means (1) that allows for easy attachment and removal of the lid (9).
2).

The drain ports (3) (4) and the upper edge of the bathtub (1) (2) (
5) one overflow hole opened in the recess (7) (8> is a drainage device (13) <13'), and a short cylindrical main body (13a) with a flange at 1.
It consists of a sub-body (13b) that is screwed onto this, and is inserted into the main body (13a) inserted into the drain ports (3), (4) and the 3-overflow hole (8) from the front side of the bathtub body (△). Accessory body (13b) from the back side of the bathtub body (A) through the gasket.
is screwed onto the bathtub body (A) around the drain ports (3), (4) and overflow hole (8).

And the drainage equipment (13) (13) of the drain outlet (3) (4)
''') are connected to the traps (15) (15', ) directly or separately via suitable connecting pipes (14), to which the drainage device (13°') of the overflow hole (8) is connected. Through a connecting pipe (16) that is connected and extends in the space (6) below the upper edge surface (5), it communicates with the secondary body (13b) of the drain device (1) of one of the drain ports (3). do.

That is, the secondary body (1) of the drain device (13) of this drain port (3)
3b) is formed into a substantially T-shaped trifurcated tube shape, and one of the openings located at opposing positions covers the main body (13) of the drainage device (13).
a), the other is connected to the connecting pipe (14), respectively, and the opening located perpendicular to these openings is the overflow hole (8).
It is connected to the downstream end of the communication pipe (16) that communicates with the.

4-Trap<15) (15') is the drain channel (a
) is bent into an inverted S-shape, and its downstream end communicates with a drain pipe (not shown).

This trap (15) (15') may be formed by one part, or may be formed by connecting a plurality of members as in the illustrated example. In addition, as mentioned above, the traps (15) and (15') do not necessarily have to be the so-called S traps in which the drainage channel (a) is bent into an inverted S-shape, and depending on the position of the drain pipe, the drainage channel may be bent. It is also optional to use a so-called P-trap in which (a) is bent into a roadside P-shape. Any other structure may be used as long as it has a trap function.

Note that (17) in the figure is a constriction portion that limits the amount of water discharged, and is formed to have an inner diameter smaller than the inner diameter of the flow path of the trap (15'). (18) are plugs for drain ports (3) and (4). To explain the function of this throttle part (17), the bathtub (2
) to lower the water level, remove the plug (18) from the drain port (4), lower the water level in the bathtub (2), and then connect the plug (18) to the drain port (4) again. ), the trap (15
The water flowing through the inside of the trap (15') closes the drain port (4) with the stopper (18), causing the inside of the flow path between the drain port (4) and the inflow side of the trap (15') to close. It becomes negative pressure.

In order to eliminate this negative pressure, the water in the 1-lap (15') flows backwards, and the force of the water causes the stopper (18) to
No. 1 water outlet (4) and water will flow out from the υl water outlet (4), making it impossible to raise the water level in the bathtub (2) to the desired height. However, in the present invention, the drainage equipment (
Since a constriction part (17) with an inner diameter smaller than the inner diameter of the flow path of the trap (15') is provided in the trap (13'), less water flows inside the trap (15') and
1., with the force of siphon action weakening within 5').

This prevents the generation of negative pressure as described above, and the water outlet (4)
The plug (18) will not come off.

FIG. 3 shows another embodiment of the present invention, in which the stopper (1) of the drain (4) is shown.
8), and drain holes (3), (4>, and overflow hole (8)) with several holes in the axial direction.
9) is attached, and the trap (15) (15'
) to prevent foreign matter such as hair from getting stuck.

Since the present invention has the above configuration, it has the following advantages.

■ Since we have provided a trap corresponding to each of the drains 1] of two adjacent bathtubs, we have installed two traps at the trap part, similar to the conventional method that connects the drains of two bathtubs to one collective trap. The bathtubs do not communicate with each other, so even if the water in the high water level bathtub and the low water level bathtub are drained at the same time, the water in the high water level bathtub will flow into the low water level bathtub and the low water level bathtub will be drained. There is no risk of problems such as getting the inside dirty.

■ The water drained from each bathtub passes through each tube□ tube, so all the water from the two bathtubs flows into one trap, just like when using a conventional collecting trap.
The trap will not become clogged, or the drainage capacity will be extremely reduced due to the clogging, and the drainage water from one bathtub will not flow into the bathtub being used and pollute that bathtub.

■ An overflow hole is provided on one side of the recess between the two bathtubs, and a drainage device is attached to this overflow hole, which connects to the upstream side of one of the traps, so they can be placed next to each other like in the past. Compared to a structure in which an overflow hole is provided on both side walls of the bathtub and a drain device is attached to the overflow hole, the number of overflow holes is smaller, making it easier and cheaper to install the IJI water appliance. be.

■ The upper edge surface that connects the upper sides of the adjacent side walls of the two bathtubs is located at a slightly lower level than the top of the bathtub, so overflow water does not flow out of the tank and flows into the overflow hole without fail, and the overflow water is The drainage device attached to the hole will not protrude upward and injure the user's hands.
