I was asking for the start time.

[0003]

However, with regard to the flow rate of filling water per unit time for calculating the required filling time, it is assumed that the pressure of the water supplied from the water supply system is low. Since the required hot water filling time was calculated using the values, the actual hot water filling time was shortened in high water pressure areas, etc., and the actual hot water was filled much earlier than the reserved bath preparation completion time, and the bath preparation was completed. There was a problem. Moreover, depending on the case, even in the state where the warming combustion has been started after the actual bathing preparation is completed, the bathing preparation completion time is not the reserved bathing preparation completion time yet, so that the notification of the bathing preparation completion does not sound, resulting in heat dissipation loss. At the same time, an unfavorable state has arisen from the viewpoint of the user.

Accordingly, the present invention solves the above-mentioned disadvantages in the conventional bath kettle apparatus having a hot-water supply function capable of performing a reserved bathing operation, and makes the time when the bathing preparation is actually completed closer to the set bathing preparation completion time. It is an object of the present invention to provide a bath kettle device with a hot water supply function that can prevent a notice of completion of bathing preparation and a time of completion of actual bathing preparation from being far apart.

Next, the reservation operation of the bath will be described with reference to FIG. The reservation operation is set, for example, by the reservation operation setting section 51 of the remote controller 50. Clock setting button 51 in advance
First, the bath reservation button 51b is depressed, and then the bathing preparation completion time is set on the display section 51d by the time setting button 51c. When the time is set, the reservation button is pressed again to confirm the reservation operation.

The control operation by the controller 40 when the bath reservation operation by the remote controller 50 is set,
This will be described with reference to the flowchart of FIG. The controller 40 when the bathing preparation completion time T _r is reserved (YES in step S1), the required hot water filling time H _n from the preset water filling amount Q _t and calculating water filling flow R _c, H _n
= Determined by the arithmetic expression of _Q t / _{R c} (step S2). And further the required hot water filling time H _n and the bathing preparation completion time T _r
To calculate the hot water filling start time T _s from the (step S
3).

[0013] The hot water filling amount Q _t is such that a predetermined water filling level according to the size and shape of the bathtub 31 may be a hot water filling amount Q _t of a predetermined quantitative. Also the bath water level is set by the subscriber, it is possible to obtain a hot water filling amount Q _t by calculation, such as the bottom area × set water level of the bathtub 31. Also the arithmetic water filling flow R _c is can be predetermined flow rate adjustable fixed by the bath automatic hot water supply controller 19.

[0014] hot water filling start time T _s is calculated as described above, the controller 40 monitors the time, at the water filling start time T _s (YES in step S4), and starts the automatic water filling hot water (Step S5). The hot water supply is performed such that the bathtub temperature reaches the bath set temperature when the hot water filling is completed. During the automatic hot water supply, the controller 40
The actual hot water filling flows through the bath 31 the flow rate R _j is the arithmetic water filling rate R baths automatic hot water supply so that the _c adjuster 19
Is controlled (step S6).

[0015] hot water supply amount of the predetermined hot water filling amount Q _t is detected by the bath automatic hot water supply flow sensor 24, an automatic water filling hot water supply is completed (YES at step S7), and the controller 40 starts the maintenance operation ( Step S8). This warming operation can be performed by performing a reheating operation when the bathtub temperature falls below the bath set temperature. Then, when the time reaches the bath preparation completion time _Tr (Yes in step S9), the controller 40 notifies completion of bath preparation (step S10). This notification can be made by voice and display through the remote controller 50 or the like. Then, the warming operation is continued (step S11). In addition to the notification of the completion of the bath preparation, the bath preparation completion time _Tr
Shortly before, a notice of completion of bath preparation, for example, "You can take a bath in another minute." Since the actual bathing preparation completion time can be made closer to the reserved bathing preparation completion time, the value of this advance notice increases.

[0016] As described above, by controlling so that the actual water filling hot water flow rate R _j at the bath automatic hot water filling hot water in the calculation hot water filling rate R _c of the required water filling time, the actual bath ready The time can be made closer to the reserved bath preparation completion time _Tr . Of course, slightly more than the actual hot water filling the hot water flow rate R _j an operation for hot water filling flow rate R _c so as not later than the bathing preparation completion time T _r reserved, or to adjust the hot water filling start time T _s to advance slightly You may do so.

Referring to FIG. 4, another control form by the controller 40 will be described. In this control mode, the control example described in FIG. 3, a method of determining the calculating water filling rate R _c used for calculation of the required water filling time H _n differs from the step S2, hot water filling in step S5-1 In the early stage of the operation, the bath automatic hot water supply controller 19 is once fully opened (step S5-2), the fully opened flow rate flowing at that time is detected and stored (step S5-3), and the next reserved operation is performed. it is different from that used as the calculation hot water filling rate R _c of the time. Other steps S1, S3 to S4, S5-1,
Steps S6 to S11 are the same as steps S1, S3 to S4, S5, and S6 to S11 in the flow of FIG. 3, respectively. Step S2 in the flow of FIG.
Controller 40 on the basis of the reserved bathing preparation completion time T _r is the step of calculating the required water filling time H _n. In the present embodiment, as the calculation hot water filling rate R _c used for calculation of the required water filling time H _n, using a full flow of bath automatic hot water that is stored in the controller 40 during their last reservation operation. The fully open flow rate is controlled by the bath automatic hot water supply controller 19.
Can be obtained by fully opening.

[0018] By an operation for hot water filling rate R _c of the full flow in the previous reservation operation, it is possible to reduce the required water filling time H _n, can be performed much bathing preparation in a short time. Of course, bringing the actual bath preparation completion time close to the reserved bath preparation completion time _Tr is the same as in the above-described embodiment. Note The calculation hot water filling flow R _c,
Using a flow rate slightly lower than the full open flow rate obtained in the previous reserved operation, the reliability of the flow rate control can be ensured. When using a flow rate slightly lower than such a full open flow rate,
In the present invention, it is assumed that the flow rate falls within the range of the full open flow rate. The reason why the fully opened flow rate at the time of the previous reserved operation is used is that the tendency of the fully opened flow rate at the previous time is considered to indicate the latest state of bath automatic hot water supply, and is considered to be applicable to the current operation. If the flow rate cannot be detected correctly at the time of the last reserved operation, the flow rate at the previous time is not stored, and the memory of the previous two times is retained and used.

In FIG. 4, when the controller 40 starts the automatic hot water supply (step S5-1), the bath automatic hot water supply controller 19 is once fully opened (step S5).
-2). Then, the fully open flow rate in the fully open state is detected by the bath automatic hot water supply flow rate sensor 24, and this is stored in the storage unit in the controller 40 (step S5-3). The storage is used as the calculation hot water filling rate R _c at the time of the next reservation operation. When the controller 40 stores the fully open flow rate, if the value is not correctly detected by the bath automatic hot water supply flow rate sensor 24, or if the value to be stored is out of the range of possible flow rate values, It is assumed that an existing value is retained without storing the value. The range outside the above range can be determined in advance by experiments or the like.
