からである。If the remote controller 60 issues an instruction for the additional heating operation, or if it is determined that the temperature inside the bathtub 1 is lower than the set value by the temperature information input from the bath temperature sensor 31 during the automatic warming operation, the additional heating operation switch Turns on. As a result, the circulation pump 26 is first driven via the control unit 50. On the other hand, the three-way switching valve 25 has a flow passage connected to the bypass passage 24 side except when the bath water is heated and when the dropped water is heated and sent to the bath 1. Even if it is turned on, the connection with the bypass 24 is continuously maintained for a certain time t 1 . This constant time t 1 is, for example, several seconds to ten and several seconds, during which the bath water circulates through the bypass 24 in a warming-up manner. Then, at time A after a certain time t 1, switching of the three-way switching valve 25 is started via the control unit 50, and the intermediate state position is temporarily held during the switching. The holding in the intermediate state position may be performed based on a command from the control unit 50, or may be held as a characteristic of the three-way switching valve 25 itself. The holding time t 2 at the intermediate state position can be set to several seconds to several tens of seconds depending on the length of the coil 23 and the like. In the intermediate position, the three-way switching valve 25 allows both the water flow from the bypass 24 side and the water flow sent from the heat exchange coil 23 side to pass to the bath 1 side.
And the amount of water flow from each is half the amount when passing alone.
When the holding time t 2 elapses, the three-way switching valve 25 starts rotating again from the stop at the intermediate state position, and the flow path from the heat exchange coil 23 side is completely matched (time B in FIG. 2). . After that, the normal reheating cycle is used. By doing so, it is possible to prevent hot water flowing from the inside of the heat exchange coil 23 from flowing into the bathtub 1 at a dash at the beginning of the reheating. That is, the temperature at which the hot water is introduced into the bathtub 1 at the beginning of additional heating gradually rises, as shown in FIG. Such an effect is particularly effective in the case of a bath pot device having a bubble bath function. In the case of the bubble bath, although not shown, the air is jetted into the bathtub 1 together with the circulating water of the bathtub, so that the force is strong and the bather or the like is greatly affected.
なお、貯湯缶体10は給湯にも使用されるもので、常時一
定温度（例えば80℃）になるよう制御される。The hot-water storage canister 10 is also used for supplying hot water, and is controlled so as to always have a constant temperature (for example, 80 ° C.).

消される。<Effect> The present invention is configured as described above, and according to the bath device according to the claims, at the beginning of the start of the bath heating,
Since the switching of the three-way switching valve is temporarily held in the middle of the process, even if circulating water remains in the hot water storage can at high temperature, the high temperature water is gradually mixed with the water from the bypass side while gradually moving to the bathtub side. Can be released. Therefore, the inconvenience that high-temperature water flows into the bathtub all at once at the beginning of reheating is eliminated.
