持されるように追い焚きすることが必要となる。2. Description of the Related Art In general, when water is initially set in a bathtub, even if it is hot water at a set hot water temperature, if it is left as it is,
The temperature of the hot water gradually decreases due to natural heat radiation. Also, when a person takes a bath, the temperature of the hot water drops. Therefore, in order to always enjoy comfortable bathing, it is necessary to reheat the water so that the hot water in the bathtub is maintained at the set hot water temperature.

た熱交換器を加熱する(ステップ3)。Now, when the reheating switch is operated,
(Step 1) First, a circulation pump arranged in the middle of the recirculating water channel connected to the bathtub is started to start circulation of hot water in the bathtub (Step 2), and subsequently, the burner is ignited. The reheating combustion is started, and the heat exchanger provided in the middle of the reheating circulation channel is heated (step 3).

(For example, 30 seconds), and when the water in the circulation channel for reheating is sufficiently replaced with the water in the bathtub (step 4), the temperature of the water located upstream of the heat exchanger in the water channel is increased. Hot water temperature TF is detected by a sensor.

(ステップ6)。Then, it is compared whether or not the detected hot water temperature TF is slightly lower than the set hot water temperature T S (1 ° C. in this example) (step 5), and the detected hot water temperature TF becomes T S −1. (T F <T S
If -1), it is determined that the hot water in the bathtub is much cooler than the set hot water temperature T S , and the mode shifts to the warm-up and post-heating operation mode until the detected hot water temperature TF reaches the set hot water temperature T S. Perform refire combustion
(Step 6).

Then, the reheating combustion is performed until the detected hot water temperature T F rises from the set hot water temperature T S by a certain temperature (2 ° C. in this example) (step 7).

前に、追焚燃焼の開始を先行させている。As described above, in the conventional automatic bath apparatus, when the reheating switch is turned on, the detected hot water temperature TF is compared with the set hot water temperature T S in step 5 to compare the temperatures. Then, before performing the temperature control in step 6 or step 7, the burner is ignited for a certain period of time (30 seconds in this example) to perform combustion. That is, conventionally, the start of the reburning combustion is preceded before shifting to the temperature control of the bath water temperature.
【0013】こうすれば、追焚スイッチがオンされる
と、即座にバーナが点火されて追焚燃焼が開始されるの
で、追い焚き感を即座に味わえるという利点がある。In this case, when the reheating switch is turned on, the burner is immediately ignited and the reheating combustion is started, so that there is an advantage that the feeling of reheating can be immediately enjoyed.

Means that every time the reheating switch is pressed, the burner is ignited and the reheating combustion is performed for a certain period of time, so that the temperature of the bathtub gradually rises. Regulation temperature T S +
If the temperature exceeds the range of 2, the temperature of the bath tub becomes very hot, and there is a possibility that the bath may be in a dangerous state.

If response is lower than the reference temperature T R determined by (T F <T R), it is to continue to add fired operation until water temperature T F reaches the set hot water temperature T S. Here reference temperature T R in the case of this embodiment, is also set by 1 ℃ lower than the set water temperature T S. That is,
T R = T S −1. It is for the following reasons.

On the other hand, if it detects the temperature T F is below the reference temperature T R close to the reference temperature T R as possible will become T F = T S = T R + 1 ℃ choose warmth additionally fired unit 40, forced add Firing means 42
It will be the same hot water temperature as when you select. That is, at the borderline where the forced reheating means 42 or the heat retention reheating means 40 is selected, the reheating feeling is the same and the usability is good regardless of which means 42 or 40 is selected. However, setting the reference temperature T R is not limited to this example, it may be a set hot water temperature T S.

(ステップ2)。When the reheating switch 50 provided on the remote controller F is operated (step 1), first,
The circulation pump 26 arranged in the middle of the circulation water passage 22 connected to the bathtub E is activated to start circulation of hot water in the bathtub E.
(Step 2).

プ3)。Immediately after the circulation pump 26 is started and before the reburning burner 32 is ignited to start reburning combustion, the reburning combustion inhibiting means 44 detects the temperature of the bathtub detected by the temperature sensor 30. It is determined whether or not the hot water temperature T F exceeds a predetermined dangerous temperature T LIM (= 55 ° C.) (step 3).
【0045】ここで、図3に示すように、循環ポンプ2

6 is not activated, the residual heat of the heat exchanger 24 is
Although the detected hot water temperature TF of the temperature sensor 30 becomes higher than the actual hot water temperature in the bathtub E by being transmitted to the hot water in the bathtub, if the hot water in the bathtub E is circulated by the circulation pump 26,
Since the hot water staying in the bath 2 is pushed out and gradually replaced with hot water in the bathtub E, the hot water temperature TF of the return hot water from the bathtub E detected by the temperature sensor 30 gradually decreases,
The value approximates the actual temperature of the hot water in the bathtub E.

0 If YuAtsushi T F to be detected is lower than the critical temperature T LIM in
In ( TF <T LIM ), the controller D judges that the danger due to the reburning combustion is small, starts the reburning combustion by igniting the burner 32, and is provided in the middle of the circulation water passage 22. The heat exchanger 24 is heated (step 4).

登録する(ステップ6)。When a predetermined time t 0 (for example, 30 seconds) elapses after the circulation pump 26 is started and the water in the circulation water channel 22 is sufficiently replaced with the water in the bathtub E (step 5), the detection output T F temperature sensor 30 is regarded as the actual water temperature of the tub, and registers the value as an initial value T F0 sod焚燃sintered (step 6).
【0050】そして、この浴槽の湯温TFが設定湯温TS
で決まる基準温度TR(=TS−1)よりも低いか否か判別
される(ステップ7)。Then, the hot water temperature T F of the bathtub is set to the set hot water temperature T S.
It is determined whether or not the temperature is lower than the reference temperature T R (= T S −1) determined by (7).

で追焚燃焼を行う(ステップ8)。If the detection output T F of the temperature sensor 30 is lower than the reference temperature T R (T F <T R ), it is determined that the hot water in the bathtub E is much lower than the set hot water temperature T S. Te, the process proceeds to insulation add-fired operation mode, heat insulating add-fired unit 40 performs additionally焚燃sintered to YuAtsushi T F detected by the temperature sensor 30 reaches the set hot water temperature T S (step 8).

When the detected output TF of 0 is lower than the reheating regulation temperature T O-MAX (= 50 ° C.) (T F <T O-MAX ), the reheating combustion interruption means 46 does not interrupt the forced reheating. , forced add-fired unit 42 performs additionally焚燃sintered until the hot water temperature T F of the bath E is increased by a predetermined from the current water temperature T F0 which had been registered as an initial value before the temperature ΔT (= 1 ℃) (step 10) (see curve indicated by reference numeral T FA of FIG 3).
