[Conventional technology]

As shown in Figure 5, the Utase bath that is used in the bathroom at home is used as a multi-functional shower by branching the hot water pipe of the water heater A and connecting it to the outlet C installed in the bathroom. It is basically the same as a shower, just the method of discharging hot water is different. In addition, in Fig. 5, d
This is a remote control for the Hautase Groove.

In the above-mentioned Utase bath, the hot water used is directly drained away, so there is a problem in that the large amount of hot water used causes a large economic loss.

Also, if you need to use a large water heater,
Water heaters are often used for other purposes, such as in the kitchen, so they are susceptible to fluctuations in water temperature when they are used at the same time.
May cause discomfort when used.

In order to improve the problems of the prior art as described above, the inventors of the present invention connected a water inlet with a filter to a bathtub, made the piping connected to the water inlet rise upward via a pump, and installed the pipe at the top of the bathtub. A discharge port for discharging toward the bathtub is connected to the end of the piping at a position higher than the bathtub, and the bathtub water pumped up by the pump is discharged from the discharge port and applied to the human body in the bathtub. We have proposed a Utase water device that collects Utase water into the bathtub.

[Problem to be solved by the invention]

According to the above-mentioned proposal, since the hot water in the bathtub is pumped to perform Utaseyu, there is no risk of fluctuations in the water temperature caused by simultaneous use of water heaters, and Utaseyu can always be performed at the appropriate temperature. In addition, most of the hot water used for the soaking bath can be recovered into the bathtub, making it possible to perform the soaking bath economically.

However, since Utaseyu originally discharges a large amount of hot water into the air, there is a risk that the temperature of the water in the bathtub will gradually drop as you use Utaseyu, making it unsuitable for Utaseyu or bathing. There is.

It is an object of the present invention to solve the above-mentioned problems and to provide a method for controlling the operation of a soaking bath that can be combined with a bath device having a reheating function to prevent a drop in the temperature of the water in the bathtub. do.

[Means to solve the problem]

In order to achieve the above-mentioned objects, the present invention provides a bath device with a reheating function that is equipped with a bath pump and a water temperature detector in the bathtub, and pumps up the hot water in the bathtub with a pump. When the Utase-yu switch is turned on, the Utase-yu pump is driven, and while the pump is running, the bath pump is driven and the temperature of the bath water is detected, and the bathtub water temperature is detected. The bath apparatus is characterized in that when it is detected that the water temperature has fallen below a certain set value, the bath apparatus is caused to perform a reheating operation.

[Effect]

As described above, the present invention combines a bath device with a reheating function and a heating device that pumps hot water in the bathtub and applies it to the human body, and when a drop in the bathtub water temperature is detected, the bath device reheats the water. Since the bath is heated, the temperature of the water in the bathtub does not drop even if a large amount of hot water is discharged into the air during the Utaseyu operation, and the bathtub can always be heated at a comfortable temperature.
