It is an object of the present invention to provide a multipurpose water discharging device which is excellent in usability and is advantageous in terms of resource saving and energy saving.

[0006]

[Means for Solving the Problems] The means for solving the above problems consists of a water tap that discharges tap water or a mixture of tap water and hot water, and a water tap that is connected to the tap water supply pipe of the water tap. ,
A switching means provided downstream of the connection part, a heat exchanger provided downstream of the switching means, and a heat exchanger provided downstream of the heat exchanger,
This is a multi-purpose water spouting device that includes a discharge section to which a small flow water spouting nozzle is connected.

[0007] The small flow rate discharge part is provided in a part of the faucet body, and the faucet body is provided with at least a small flow rate opening/closing operation part;
These include oral cleaning nozzles, intermittent spray nozzles, hair styling nozzles, etc., and the various nozzles are detachable and replaceable.

[0008]

[Function] According to the above means, a small flow discharge part is provided separately from the spout of the faucet, and a dedicated heat exchanger is provided to obtain hot tap water with a small flow rate, so it can be used for oral cleaning, hair styling, etc. The necessary pressurized hot water can be obtained without relying on the water heater of the faucet, and pressure hot water for cleaning, etc. can be obtained quickly and with good hot water properties as needed, and this can be provided integrally with the faucet. Therefore, it has excellent functionality and ease of use, and since there is no need to waste water, it is preferable from the viewpoint of resource and energy conservation.
