Abstract

PROBLEM TO BE SOLVED: To easily set a waterproof pan with a trap in a neat state by mounting a duckboard-like grating on the entire upper surface of the waterproof pan with the trap to which a drainage hose of a washing machine can be connected. SOLUTION: A waterproof pan 1 with a trap to which a drainage hose of a washing machine can be connected is embedded in a floor on one side of a wash basin. A frame body 5 having a Z-shaped cross section is fixed to a location below a periphery 1c of the pan 1, which horizontally externally extends from an erection portion 1b of the waterproof pan 1. A flange 5a of the frame body 5 is fitted into an opening K of a floor member F, and arranged so as to cover the upper surface of a water receiving portion of the waterproof pan 1. Further, the flange 5a is abutted to the upper surface of the periphery 1c so as to be flush with the floor surface of the floor member F. Thus, the waterproof pan can be easily set in a neat state without concern for the dimension of the washing machine.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drainage system for a washing machine.

[0002]

2. Description of the Related Art Conventionally, for example, in an old apartment house, as shown in a plan view of FIG.
A bathroom 52 is formed on the side of the washing machine, and a toilet 53 is formed in the vicinity of the bathroom 52.
In many cases, a washing machine is installed on the waterproof pan 55. Conventionally, as shown in an enlarged view in FIG. 6, the waterproof pan 55 is formed larger than the washing machine 59, and is integrally formed. A trap 58 is formed, and a hose 60 from a washing machine 59 is connected to the trap 58 to drain the water. A pipe 61 is provided from the waterproof pan 55 to the vertical water pipe 56 of the building. Conventionally, the waterproof pan 55 takes up a space because it is larger than the washing machine 59 mounted thereon, and the washing machine 59 mounted thereon is limited due to the size of the waterproof pan. In addition, there is a problem that the washing machine is replaced when the washing machine is replaced, and it is necessary to prepare several types of waterproof pans 55 according to the size of the washing machine.

For the purpose, the first gist is that the entire area of the upper surface of the waterproof pan with a trap to which the drain hose of the washing machine can be connected,
This means that a saw-shaped grating is placed.
A second gist is that the waterproof pan with the trap is installed under the floor so that the grating is flush with the floor. A third gist is that a frame having a flange is fixedly provided on the outer periphery of the upper surface of the waterproof pan with a trap, the grating is fitted into the frame, and the flange of the frame is attached to the floor surface. It is to be fixed to the formed opening.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows a state in which a waterproof pan 1 is installed in a buried state on a floor surface beside a wash basin 54, and the washing pan 5
FIG. 9 is a plan view showing a state in which a water-absorbing pan 9 is installed. A bellows hose 60 for draining water from a washing machine 59 is connected to a trap 2 provided in the waterproof pan 1, and a pipe 3 from the waterproof pan 1 is moved under the floor. FIG. 2 is an enlarged plan view of the waterproof pan 1, and FIG. 3 is a cross-sectional view of the waterproof pan 1 buried in the floor. It is. FIG. 4 is an exploded view of a main part of components of the waterproof pan 1.

In the drawing, a rising portion 1b is integrally formed on the outer peripheral side of a horizontal water receiving portion 1a of a waterproof pan 1, and the rising portion 1b is formed.
An outer peripheral portion 1c extending horizontally outward from b is formed, and a frame 5 having a Z-shaped cross section is fixed below the outer peripheral portion 1c. The flange portion 5a protruding in a shape is fitted into an opening K formed in the floor material F constituting the floor surface, and the flange portion 5a is brought into contact with the upper surface of the floor material F, so that the waterproof pan 1 is attached to the floor material F. Are screwed into the corners of the flange 5a from above, as shown in FIG.
The frame 5 of the waterproof pan 1 is fixed and supported on the floor F. A trap 2 is provided in a suspended shape at the center of the water receiving portion 1a, and an L-shaped rotary connection portion 4 is provided rotatably upward from the trap 2;
The bellows hose 60 is configured to be connected to the rotating connection portion 4 from the washing machine 59.

Further, in the waterproof pan 1 of this embodiment, a grating 6 is provided so as to be fitted inside the frame 5, and the grating 6 is formed in the shape of a saw.
It is covered with the upper surface of the water receiving portion 1a and is in contact with the upper surface of the outer peripheral portion 1c, and is flush with the floor surface made of the floor material F. That is, in a state where the frame 5 is fixed to the floor material F via the screws 7 and the grating 6 is fitted in the frame 5, the grating 6 is arranged flush with the floor surface.

As shown in FIG. 4, the frame 5 is formed of an aluminum sash, and the outer peripheral portion 1c of the waterproof pan is fixed to the frame 5 via fixing screws 8 in advance. Therefore, when the waterproof pan 1 is installed, the water receiving portion 1a is disposed below the floor surface, and the grating 6 is flush with the floor surface. The grating 6 has a strength enough to withstand the load even when a person, a washing machine 59 or the like is placed above. A pipe 3 is connected to a side surface of the trap 2, and the pipe 3 is connected to a floor material F.
And a slab floor surface S, and is connected to the existing vertical drain pipe 56 of the apartment house described above.

In such a structure, the waterproof pan 1 can be installed neatly and buried on the floor surface, the grating 6 can be flush with the floor surface, and the washing machine 59 can be placed thereon, The washing machine 59 can be placed directly on the floor and at a free position on the grating 6, the size of the washing machine 59 is not limited, and even if water overflows, the water overflows well through the grating 6. Is received by the water receiving section 1a and the trap 2
And can be satisfactorily received by the water receiving portion 1a and flown to the trap 2 even if water leaks from the connecting portion between the bellows hose 60 and the rotary connecting portion 4. Becomes

[0009]

According to the drainage system for a washing machine of the present invention, the waterproof pan with a trapezoidal shape is placed on the entire upper surface of the waterproof pan with a trap to which the drainage hose of the washing machine can be connected. The upper surface of the grate can be covered with grating to make it a neat configuration, and even if people or things are placed on the grating, the strength can be secured,
The leaked water can be satisfactorily flowed through the grating to the waterproof pan below.

Further, by installing the waterproof pan with the trap under the floor so that the grating is flush with the floor, the grating is flush with the floor and under the floor below the waterproof pan. Is installed, and the installation state is extremely clean and compact.

A frame having a flange portion is fixedly mounted on the outer periphery of the upper surface of the waterproof pan with a trap. The grating is fitted into the frame, and the flange portion of the frame is formed on the floor surface. The frame is fitted to the opening on the floor surface by being fixed to the opening, and even if the dimensions of the opening are misaligned, the opening is concealed with the frame, and the opening is satisfactorily inserted through the frame. The waterproof pan can be fixed and supported flush with the floor surface, so that the waterproof pan can be easily installed and a neat installation state can be obtained.
