Zusammenfassung: | PURPOSE:To enable a simultaneous hot water taking from an upper layer hot water and a lower hot water layer and further enable a selection of the upper layer hot water and the lower layer hot water by varying a fixed position of a cap and a double pipe by a method wherein the double pipe for taking hot water separately for the upper layer hot water and the lower layer hot water is fixed to the hot water taking port and further the cap for enclosing the double pipe is constituted. CONSTITUTION:One end of an inner pipe 4a of a double pipe 4 has a suction port 4d, the other end of the double pipe has a hot water feeding port 4e, and a plurality of first flowing ports 4f are formed on an outer circumference near the connection part 4c for the outer pipe 4b. The outer pipe 4b is formed with a plurality of second flowing-out holes 4g at the connection part 4c with the inner pipe, the other end of it is communicated with the lower water level in the hot water storing container 1 through the suction port 4h and at the same time the hot water storing container 1 is fixed to the hot water taking port 1b. The cap 5 has a stepped section shape, the cap is inserted into an inner pipe 4a and an outer pipe 4b of the double pipe 4, respectively, and each of the first flowing-out hole 4f and a second flowing-out hole 4g is enclosed thereby, respectively, and at the same time it is fixed to the inner pipe 4a and the outer pipe 4b of the double pipe 4 with a hose band 6 from the outer circumferential stepped surface of the cap. |
