連通する型式とした。(Example) An example of implementing the present invention will be explained with reference to attached drawings. In the drawings, reference numeral 1 indicates an outer shell in which a hot water supply pipe 2 extending from the water heater main body constitutes the rectifier main body, and the outer shell 2 has a cylindrical inlet 3 fitted to the tip of the hot water supply pipe 1 on its upper surface. and an outflow port 4 on the bottom surface, and a large diameter opening 5 on the top surface facing the inflow port 3 inside.
, an inner shell 7 having a small-diameter hot water supply hole 6 on the lower surface facing into the outlet 4, and a separator 8 on the upstream side of the hot water supply hole 6. In the illustrated embodiment, the outer shell 2 is provided with a middle shell 9 below the inner shell 7 surrounding the inner shell 7, and the middle shell 9 communicates with the outlet 4.

面積を増大させることが好ましい。 Although the above is not particularly different from the conventional one, according to the present invention, the separator 8 is made to face the inside of the inlet 3 and is formed integrally with the outer shell 2. More specifically, the separator 8 is provided in a slit grid shape or the like so as to face the inlet 3 at a position above the hot water supply hole 6, which is largely separated from the hot water supply hole 6. In this case, the separator 8 is shown in FIG. It is also possible to extend the inlet 3 downward and provide it on the lower end surface as shown by the chain line. Further, it is preferable that the separator 8 is formed into a substantially hemispherical curved surface as shown in the figure to increase its effective cross-sectional area.

率にすることが出来る。(Function) To explain its function, high-temperature water guided from the hot water supply pipe 1 to its lower side via the inlet 3 is passed from inside the inner shell 7 to its lower side via the hot water supply hole 6 on the lower surface of the inner shell 7. While the steam to be separated rises once inside the inner shell 7, it is led from its outer periphery to the outlet 4 on the lower side, and this point is not particularly different from the conventional one. According to the present invention, the inlet 6 is provided with the separator 8, and the high temperature water first hits the separator 8 to separate the steam contained therein before being introduced into the inner shell 7. In this way, vapor separation can be performed with high efficiency. That is, the separator 8 is located above the hot water supply hole 6 and is largely separated from the hot water supply hole 6, so that the steam separation can be performed with high efficiency.

構成を簡単且廉価にする等の効果を有する。(Effect of the invention) As described above, according to the invention, the separator is provided so as to face the inlet above the hot water supply hole, which is largely separated from the lower hot water supply hole, and the separator is placed close to the hot water supply hole and placed around the upper outer periphery of the hot water supply hole. Steam separation can be carried out more efficiently than the separator that is formed on the receiving surface of the outer shell, and the separator is formed integrally with the outer shell in advance, compared to the separator that has a separate wire mesh or the like. This has the effect of simplifying the configuration and making it inexpensive.
