A lower end portion of the sliding valve 34 extends into the ceiling space of the first cylinder 4 a of the filtration container 4 and is attached with a float 35 to constitute a metered water feeder 31.

When the amount of water in the first cylinder 4a increases, the float 35 rises and the sliding valve 34 opens the discharge hole 33a. For this reason, the water supplied to the receiver 33 from the outlet 30a flows down from the discharge hole 33a and is supplied into the first cylinder 4a.
Further, when the amount of water in the first cylinder 4a decreases, the float 35 descends and the discharge hole 33a is closed by the sliding valve 34. Thereby, the flow of water from the receiver 33 stops, and the water supply into the 1st cylinder 4a stops. In this manner, the sliding valve 34 opens and closes the discharge hole 33a in accordance with the water level Lp into the first cylinder 4a, thereby controlling the amount of water supplied into the first cylinder 4a and controlling the first cylinder 4a. The water level Lp is kept constant.

Can be tied.

Moreover, by installing the filtration container 4 in the cooling chamber 2, water from the outlet 30 a of the water supply source 30 is filtered by the filtration container 4 and simultaneously cooled by the cooling chamber 2. For this reason, the effect similar to Example 1 is acquired also in Example 6. FIG.
In FIG. 7, the upper portion of the first cylindrical portion 2 a in the filtration container 4 is positioned outside the cooling chamber 2, but the entire filtration container 4 may be disposed in the cooling chamber 2. The same applies to the filtration container 4 in Example 7 of FIG.

The proximity sensor 41 detects the water level Lp in the first cylinder 4a of the filtration container 4, and controls energization of the electromagnetic valve 40 via an energization control unit (not shown).
By this energization control, the electromagnetic valve 40 is opened / closed according to the water level Lp in the first cylinder 4a, so that water from the water supply source 30 flows from the opening / closing valve 40a into the cooling chamber 2 through the pipe 31a and the outlet 30a. The water level Lp in the first cylinder 4a is kept constant by adjusting the amount of water.

  In the seventh embodiment, similarly to the sixth embodiment, since the filtration container 4 and the cooling chamber 2 are located in a single common space, the water supply from the outlet 30a of the water supply source 30 to the cold water cock 18 and the hot water cock 13 is provided. The route and the hot water supply route can be connected with the shortest distance.
