It may be a purified water tank (not shown) in which filtered water, that is, purified water is stored. However, the water supply source is not particularly limited, and is connected to the water inlet 210 and may be any well-known as long as it can supply water to the water inlet 210 .

The inlet 210 may be provided with a sensor installation unit 211 as shown in FIGS. 1 to 3 . A temperature sensor ST may be installed in the sensor installation unit 211 as shown in FIGS. 3 and 4 .

Acquisition sealing connection member 220 may have an acquisition connection flow path 221 formed. The inlet connection passage 221 may be connected to one end of the inlet 210 and the heating passage RH. Accordingly, the water introduced into the water inlet 210 may be introduced into the heating passage RH through the inlet connection passage 221 as shown in FIG. 6 .

As such, when the shape of the heating flow path RH is spiral, the contact area between the water flowing through the heating flow path RH and the heating unit 400 , for example, the heat transfer member 410 of the heating unit 400 may be increased. Accordingly, the water flowing through the heating flow path RH can be heated more rapidly, for example, instantaneously, to a predetermined desired temperature of hot water.

However, the configuration and shape of the cover part 600 is not particularly limited, and any configuration and shape is possible as long as the configuration and shape can cover the acquisition part 200 and the heating part 400 and the water outlet part 500 .

An installation hole 611 may be formed in the portion of the cover 600 on the water outlet 500 side. For example, an installation hole 611 may be formed in a portion of the water outlet 500 side of the first cover member 610 . A bimetal BM may be installed in the installation hole 611 as shown in FIGS. 1 and 3 .

The bimetal BM may indirectly contact the heat transfer member 410 of the heating unit 400 by the contact member CM. Also, the bimetal BM may be electrically connected to the heater 420 of the heating unit 400 or a controller (not shown) electrically connected to the heater 420 . And, when the temperature of the water flowing through the heating flow path RH formed between the heat transfer member 410 of the heating unit 400 and the flow path forming member 310 of the flow unit 300 is heated to a predetermined desired temperature or higher, it is overheated , the bimetal BM may be operated to prevent the heater 420 from being electrically connected to the power source.

As described above, when the water heater according to the present invention is used, the inlet port through which water is introduced and the outlet port through which hot water is discharged are connected to the heating flow path formed together by the flow part through which water flows and the heating unit for heating water by a sealing connection member. It can be connected in a hermetically sealed manner, and the heating flow path can be reliably sealed, no toxic odor is generated from the moving part by heating of the heating part, and water cannot leak to the outside even after long-term use.

The water heater described as described above may not be limitedly applicable to the configuration of the above-described embodiments, but may be configured by selectively combining all or part of each of the embodiments so that various modifications may be made.
