使用面でも大きな問題であつた。 When hot water is supplied to the bathtub 5 by the heat exchanger A2, when the hot water tap B7 is opened, fuel is supplied to the heater A10 by the fuel controller A12, and the setting device 1
Hot water supply starts at the hot water temperature according to 4. At this time, the bathtub 5 is in an open state, which causes a large heat radiation loss and poses a problem in energy saving. The hot water supply is stopped mechanically by the hot water tap 10, but since this operation is instantaneous, water hammer occurs and the hot water supply system vibrates abnormally. This phenomenon becomes more severe the higher the water supply flow rate (more than 8/min) and the higher the water pressure, and since it is a pressure wave, it affects other water piping parts and reduces durability.
This was also a big problem in terms of usage.

御部が作動した後に行う構成である。Structure of the Invention In order to achieve this object, the present invention divides the outlet part of one forced water flow type heat exchanger (hereinafter referred to as heat exchanger A) in the appliance body, and uses the other natural water as a pouring circuit. Alternatively, it can be configured to supply water to a forced circulation heat exchanger (hereinafter referred to as heat exchanger B), with a valve drive unit in the pouring circuit, a supply water flow control unit at the inlet of heat exchanger A, and a water level detector in heat exchanger B. The valve drive unit is opened by the setting unit and closed after the water supply control unit is activated by the signal from the water level detector. .

い勝手面での効果も得られるものである。 At the same time as the setting device starts heating the heat exchanger A, the valve drive section opens, and hot water is supplied into the bathtub via the heat exchanger B. At this time, the bathtub can be kept in a sealed state (with a lid), which prevents heat loss and saves energy. Furthermore, when the desired water level is reached, the supplied water flow rate control unit regulates the flow rate to a small amount based on the signal from the water level detector, so no water hammer occurs even if the valve drive unit is closed. Therefore, when hot water is supplied, a large flow rate can normally be set, making it possible to supply hot water to the bathtub in a short period of time, and providing benefits in terms of usability.
