The pipe portion is inserted into an insertion port formed at the bottom of the hot water tank, and is provided in the communication path so as to be openable and closable for draining water.
[0009]
In the local cleaning device of the present invention, since the communication path of the water supply mechanism can be opened and closed for draining water, there is no need to provide an opening for draining in the hot water tank, the structure of the hot water tank is simplified, and the manufacturing cost is reduced. Low cost can be realized.
[0010]
Of course, when the communication path of the water supply mechanism can be opened and closed for draining, the structure of the water supply mechanism itself cannot be denied. However, the water supply mechanism originally has a complicated structure with a built-in electromagnetic valve and a flow rate adjustment valve in order to appropriately replenish the hot water tank with cleaning water supplied from the water pipe. For this reason, even if the communication path of this water supply mechanism can be opened and closed, the cost does not increase significantly. On the other hand, the cost can be greatly reduced by omitting the opening of the hot water tank.
[0011]
Therefore, the local cleaning apparatus of the present invention can realize a reduction in manufacturing cost.
