[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a washing machine bread installed on a floor such as a house.

[0002]

2. Description of the Related Art In a laundry such as a house, it is complicated to construct a tiled or other waterproof structure, which requires a long construction time and a high construction cost. A dish-shaped washing machine pan (hereinafter simply referred to as a pan) installed on a surface is used. However, under the floor of a laundry such as a house, there is a pipe space, and water pipes, hot water pipes, drain pipes, gas pipes, and other pipes are laid, and it is necessary to check for leaks in these pipes. Becomes Therefore, although an inspection port for pipe inspection is provided, providing an inspection port on the floor surface requires not only careful construction and appearance, but also tends to be avoided in terms of construction cost.

[0003]

[Problems to be Solved by the Invention] In the present invention, an inspection port for the underfloor piping space is provided on the bottom of the pan, and an opening is formed in the floor base opposite to the inspection port. It is an object of the present invention to provide a washing machine bread in which a mouth is concealed, a floor base opening for inspection is easily constructed, and construction cost can be reduced.

[0004]

According to the present invention, an inspection port is provided at a substantially central portion of a dish-shaped bread main body having a drain port, and an openable cover is provided on the inspection port in a water-tight manner. A backing material supported on the periphery of the floor base opening is fixed to the back surface.

[0005]

In order to install the bread of the present invention, the bread is installed with the inspection opening facing the opening of a predetermined size provided in the floor base at the position designated in advance, and the periphery of the bread is placed on the floor or the floor. The wall is sealed with a sealing material, and the inspection port of the bread is covered with a cover lid. Inspection of each pipe under the floor can be performed using the floor base opening by removing the cover of the inspection port without moving the pan. The lid that covers the inspection port of the bread shall be watertight by providing waterproof packing between the peripheral edge and the pan, but the opening of the floor base shall be smaller than the inspection port, and the backing If the size of the backing material is made to be supported by the periphery of the floor base opening, the strength of the cover will increase, and even if a load is applied to the cover, water leakage due to deformation, cracks, etc. will be prevented. Can be prevented.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to the drawings. In FIGS. 1 and 2, the peripheral portion of a dish-shaped pan 1 is fixed to a floor base 11 with screws 2 and A drain port 3 to which a drain trap T is connected and an inspection port 4 are provided on the bottom surface. A transparent or opaque cover 5 is opened and closed at the inspection port 4 so that the peripheral portion is fixed to the bottom of the pan by screws 6. Is provided. Water is prevented from leaking between the cover 5 and the bottom of the pan by the waterproof packing 7. As shown in FIG. 2, the opening 13 of the floor base 11 is smaller than the inspection port 4, and is larger than the opening 13 on the back surface of the cover 5. If the backing material 8 such as a plywood of such a size as to be supported by the peripheral portion of the opening 13 is fixed, the strength of the cover 5 is increased, and even if a load is applied to the cover 5, water leakage due to deformation, cracks, etc. occurs. Can be prevented. The bread 1 is integrally formed using a metal plate or a hard synthetic resin as a material of the bread 1, but a soft synthetic resin sheet can also be used. The cover 5 is provided detachably on the top.

In order to install such a bread 1, first, an opening 12 for a drain trap T is provided at a position corresponding to the drain hole 3 of the bread 1 on a floor base 11 at a place where the bread 1 is installed, and an inspection is performed. An opening 13 is also provided at a position corresponding to the opening 4. In particular, the area of the opening 13 is, for example, 360 mm × 30 so that the opening area of the opening 13 is smaller than the opening 4.
In the case of 0 mm, “the area of the floor base opening is 250 mm
It is desirable to attach a precautionary note such as “reduce the size to × 200 mm or less” to the bread 1. In the figure, reference numeral 14 denotes a concrete slab, and reference numeral 15 denotes a support member at the periphery of the opening 13.

As shown in FIGS. 3 and 4, a drain trap T connected to the drain port 3 of the bread 1 has a rising short pipe 22 serving as a trap screwed into a lower part of the inside of a main body 21, and
The upper end is connected to the drain port 3 and the lower end rises in the upper part of the inside 1
2 is provided with a drooping short tube 23 which can be freely inserted and removed, and a flexible tube 24 for facilitating centering is provided at the outlet, and a drainage pipe 25 is preferably connected to this. The drain port 3 of the bread 1 is covered with a garbage repellent 26. Therefore, by removing the refuse repellent 26 and removing the hanging short pipe 23 and the rising short pipe 22, cleaning such as high-pressure washing of the drainage technical pipe 25 can be easily performed. Numeral 27 denotes a short pipe for attaching a washing machine drain hose (not shown) rotatably connected to the garbage shelter 26.

[0009]

As described above, according to the present invention, an inspection port is provided at a substantially central portion of a dish-shaped bread body having a drain port, and an openable cover is provided at the inspection port in a watertight manner. The opening for checking the underfloor piping of the underfloor is always concealed by a pan, facilitating construction work of the underfloor opening, and the backing material supported by the periphery of the underfloor opening is fixed to the back of the cover. As a result, the strength of the cover is increased, and even if a load is applied, water leakage due to deformation, cracks, or the like of the cover can be accurately prevented.
