This is a waterproof pan for a washing machine that includes a fixing portion 2 for fixing the joint pipe 5 and closes the communicating portion 1d by inserting the closing member 3 from below the waterproof pan body 1.

  In the construction of the waterproof pan for a washing machine performed as described above, whether or not the connection between the water supply pipe Q and the joint pipe 5 is reliably maintained even when the construction is completed is the inspection mechanism 4 provided in the closing member 3. This can be confirmed by visually checking the inside of the closing member 3 from the inspection window 4a. Since the connection location of the water supply pipe Q and the joint pipe 5 is above the floor surface F on which the waterproof pan for washing machines is installed, it is easy to visually recognize from the inspection window 4a.

The washing machine waterproof pan configured as described above and the washing machine S placed on the washing machine waterproof pan are used as follows.
When washing is performed using the washing machine S, the handle portion 5a of the joint pipe 5 provided in the waterproof pan for the washing machine is operated so that the washing machine S can be supplied with water. By using the washing machine S in this state, water supply required for washing is supplied to the washing machine S via the water supply pipe Q, the joint pipe 5, and the water supply hose pipe Q1, and used for washing.
Moreover, the water supply used for washing is discharged to the sewage side through the drain hose pipe H1, the drain trap 6, and the underfloor pipe as drainage.

  In addition, when the washing machine S, the water supply hose pipe Q1 or the drainage hose pipe H1 breaks or the like and the water leakage occurs in the waterproof pan for washing machine configured as described above, After being received and stored on the part 1a, it is discharged from the drain port 6d of the drain trap 6 attached to the waterproof pan for a washing machine to the sewage side through the drain trap 6 and the underfloor piping.

Moreover, about the waterproof pan for washing machines comprised as mentioned above, the water supply to the washing machine S from the water supply pipe Q can be freely performed by operation of the handle | steering-wheel part 5a with which the waterproof pan for washing machines was equipped. By utilizing this and opening / closing the joint pipe 5 each time it is used, even if the water supply hose pipe Q1 is damaged other than when the washing machine S is used, it was originally present in the water supply hose pipe Q1. Since water other than water supply does not flow out on the waterproof pan for washing machines, water supply is hardly wasted. Further, if the water supply hose pipe Q1 is damaged while the water supply pipe Q is opened, the amount of water supplied on the waterproof pan for the washing machine increases and exceeds the treatment amount of the drain trap 6, and the washing machine The water supply may overflow from the waterproof pan to the floor F. However, the water supply hose pipe Q1 is damaged by opening and closing the joint pipe 5 each time it is used, except when the washing machine S is used. However, it is possible to prevent the water supply from overflowing from the waterproof pan for the washing machine onto the floor surface F.
The operation of the handle portion 5a for opening / closing the water supply pipe Q is as follows. The handle portion 5a is disposed on the outer side (front side) of the waterproof pan for washing machine, and the upper end of the frame portion 1c of the waterproof pan for washing machine is Since it is configured to be higher than the upper end of the handle portion 5a, the handle portion 5a does not interfere with the washing machine S even when the washing machine S is placed on the upper side. The operation of opening / closing the water supply pipe Q is easy.
Of course, it is extremely rare that the water supply hose pipe Q1 is damaged, and it is determined that the water supply hose pipe Q1 will not be damaged, and the water supply pipe Q is opened regardless of whether the washing machine S is used or not. It can be left as it is.
