Description

  The present invention relates to a waterproof pan for a washing machine.

  The waterproof pan for a washing machine is an important facility for receiving water discharged from the washing machine and guiding it to a drain pipe in a house and preventing water leakage to the floor or the like. A general washing machine waterproof pan has a substantially rectangular shape, and a washing machine is disposed on the pan, and the drain nozzle of the washing machine is connected to the drain plug of the drain, thereby leading the drain of the washing machine to the drain pipe. be able to.

  By the way, the drainage pipe through which the waste water of the washing machine flows is used to flow water containing detergent, dirt, etc., and the inside of the pipe is easily contaminated. Therefore, regular cleaning is essential.

  In general, the pipe is cleaned by inserting a hose from a drain outlet and ejecting high-pressure water from the tip of the hose into the drain pipe to remove dirt and the like in the drain pipe. However, a drain trap with a relatively complicated structure is often placed between the drain outlet and the drain pipe in order to prevent backflow of odors and the like in the drain pipe. It is often necessary to introduce the hose after removing it to the extent that it can be inserted.

  However, in order to remove the drain trap or the like, the washing machine must be moved, which is problematic. In recent years, the weight of the washing machine itself has increased due to the advent of drum-type washing machines and the like, and it is becoming more difficult to move the washing machine. In addition, in a housing complex such as a condominium, since it is necessary to clean a large number of pipes in a short time, the time that can be allocated to each door is further shortened, and depending on the situation, the work may not be performed.

  For such a problem, for example, as shown in Patent Document 1 below, a waterproof pan for a washing machine is disclosed which has a substantially rectangular shape and has mounting portions formed at four corners.

The words “first” and “second” themselves do not have a special meaning. This also applies to the “first drain pipe” and the “second drain pipe”.

  Further, in the waterproof pan 1, the first drain port 2 is connected to the first drain pipe 5 through the drain trap 4. More specifically, the first drain port 2 in the waterproof pan 1 has an opening formed at the tip of the drain nozzle 41 of the drain trap 4 installed in the opening 111 formed in the bottom member 11. It has become. A schematic end view of the vicinity of the first drain port 2 is shown in FIG. With this configuration, the waterproof pan 1 can discharge the waste water from the washing machine through the drain trap 4 and the first drain pipe 5 to a common drain pipe outside the house. In the present embodiment, the structure and shape of the drain trap 4 are not particularly limited, and a known drain trap can be employed. In the present embodiment, for the sake of explanation, the first drain port 2 is used as the opening of the drain nozzle 41. However, if the drain nozzle 41 is not provided, the opening of the drain trap 4 is used. It can be said that only itself (or the opening 111 itself formed in the bottom member 11) is a drain outlet. That is, the drain outlet means an entrance for discharging the waste water from the washing machine to the first drain pipe.

  Further, in the waterproof pan 1, the first drain port 2 is disposed at a position deviating from the center position. More specifically, it is arranged at a position close to any one side of the substantially rectangular bottom. However, the position of the first drain port 2 can be adjusted as appropriate, and may be at the center of the substantially rectangular bottom surface, and the position is not limited.

  Moreover, in this waterproof pan 1, the 1st drain pipe 5 is connected to the drain trap 4 as mentioned above, and discharges the waste water supplied from the 1st drain port 2 to the common drain pipe outside a residence. belongs to.
