Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a drain trap having a function of preventing backflow of water flow.

[0002]

[Prior art]

 For example, the drainage channel for draining the water in the bathtub and the drainage channel for draining the water in the floor of the bathroom may collectively be drained by one drainage channel. In this case, a drain trap is provided in the drainage channel, but the conventional drain trap has a serpentine shape with an S-shape lying down. Therefore, if the water force from the bathtub is strong, the trap becomes a resistance, and there is a risk that the trap will flow back to the drain port that opens to the low floor.

[0003]

[Problems to be solved by the device]

 The present invention has been made in view of the above point, and its problem is to prevent backflow of water from a high water level side to a fixed position drainage port in a drainage trap in which two systems of waterways gather. To do.

[0004]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the present invention is provided in a portion where the first and second drainage channels 3 and 4 communicating with the first and second drainage ports 1 and 2 provided inside and outside the tank are provided, The drainage trap provided to prevent the drainage discharged in the state in which the water level in the tank is higher than the height of the second drainage outlet 2 outside from overflowing from the second drainage outlet 2, 3, a main body 6 having an inflow port 5 communicating with 3, an inner cylinder 7 provided inside the main body 6 so as to introduce the drainage of the second drainage channel 4, and an inner body capable of floating according to the water level in the main body 6. The float valve 9 is incorporated in the cylinder 7 and comes into contact with a seat 8 provided on the inner cylinder 7 by levitation to shut off overflow to the second drainage port 2.

[0005]

Embodiments will be described below with reference to the drawings. In the embodiment, as shown in FIG. 4, the first drain port 1 inside the tank provided at the bottom of the bath A and the first drain port 2 outside the tank provided on the bathroom floor are connected to the first drain port 1. , A trap provided in a portion where the second drainage channels 3 and 4 gather.

In the example shown in FIG. 1, the main body 6 of the trap includes a base portion 11 having an inverted U-shaped meandering portion 10 on the outlet side, a trap tray 12 connected to the upper portion thereof, and a trap tray 12. It comprises a connecting pipe 13 which communicates with the second drainage port 2, and a first inflow port 5 is opened on the side surface of the connecting pipe 13 so that the first drainage channel 3 is connected.

Reference numeral 14 is a lower connecting tube that connects the trap tray 12 and the connecting tube 13, 15 is an upper connecting tube that connects the connecting tube 13 and the second discharge port 2, and 16 is screwed into the lower connecting tube 14. The ring 17 is a protrusion protruding from the trap tray 12 at a position surrounding the outer circumference of the ring 16, and together with the adjusting screw 18, constitutes a mechanism capable of correcting the deviation between the lower connecting cylinder 14 and the second outlet 2. To do.

The upper connecting cylinder 15 has a sealing material 19 composed of a 0-ring or the like on the upper outer periphery, and by inserting the connecting cylinder 15 into the connecting cylinder 21 of the mouth frame 20 provided with the second discharge port 2. Connected in a watertight manner. With this connection structure, the mouth frame 20 can be connected without turning.

An inner cylinder 7 is provided inside the main body 6 so as to introduce the drainage from the second drainage port 2. The inner cylinder 7 is connected to a substantially bowl-shaped receiving member 22 that is locked to the inner step of the mouth frame 20 to receive drainage from the second drainage port 2, and a lower end connecting port 23 of the member 22. The lower end of the tubular member 24 extends downward from the main body.

The bowl-shaped receiving member 22 is formed of an elastic material such as rubber and facilitates connection with a tubular member 24 formed of a vinyl chloride pipe or the like. Further, the elastic connection enables the inner cylinder 7 to be mounted in the main body together with the float valve 9 from the mouth frame 20 side.

Reference numeral 28 denotes a receiving member that receives the float valve 9 and is attached to the lower end of the tubular member 24. The tubular member 24 has an opening 29 through which the drainage water from the second drainage port 2 flows out. The drainage enters through the annular opening of the receiving member 28 and surely pushes up the float valve 9.

The float valve 9 floats in the tubular member 24 of the inner cylinder 7 according to the height of the water surface, contacts the seat 8 at the upper part of the inner cylinder at the time of maximum floating, and directs a water flow from the bottom to the top, that is, a reverse flow. Cut off. Incidentally, 25 is a third drainage channel connected to the outlet side of the main body, 26 is a water faucet provided in the mouth frame 20, and 27 is a filter.

2 and 3 are examples suitable for a case where there is a small difference in height between the first drainage channel 3 and the third drainage channel 25. In this example, the connecting pipe 13 in the main body 6 is shortened and changed to a member 13 'which also has a connecting function for the upper and lower connecting cylinders 14 and 15. Further, the first inflow port 5 formed in the connecting pipe 13 in the above example is moved to the side surface of the base portion 11. Since other configurations may be the same as those in the example of FIG. 1, the reference numerals are used and the description thereof will be omitted.

In such a configuration, when the drainage water from the bathtub A is drained through the trap, the water force is strong when the water level in the bathtub is high, so that the resistance of the meandering portion 10 causes the water to overflow from the second drainage port 2. try to. However, the drainage flow only pushes up the float valve 9 in the inner cylinder 7, and even if the float valve 9 is pushed up to the maximum height, it contacts the seat 8 and blocks the water channel, so flooding does not occur (Fig. 3).

[0015]

[Effect of device]

 Therefore, according to the present invention, with respect to the drain trap provided in the portion where the water flows of the two systems join, even if a strong water flow flows from the high water level side, the water flow can be stopped by the float valve 9, so that the low position There is an effect that drainage can be smoothly performed without overflowing from the second drainage port 2 at. Further, according to the present invention, since the heights of the main body 6 and the inner cylinder 7 can be easily adjusted, there is a feature that it can be easily performed even when the installation conditions are different, such as the bathtub and the floor of the bathroom.
