考えられる検知機能としては不都合があった。However, in the conventional bath device, when the bather stays in the bathtub, the bather stays in the bathtub, such as the aftermath which is a water surface fluctuation that lasts for a long time. In order to distinguish water surface fluctuations when there is no such water surface fluctuations from water surface fluctuations caused by body movements, a method is proposed in which the bather determines that the bather has left the bathtub and then cancels the body movement detection and the remote control display of the results. Has been done.
However, with such a method, for example, when the grandchild and the elderly co-bath and only the grandchild goes out first, the water level may be temporarily increased even when standing up to get out of the bath or when taking a bath with multiple people. There is an inconvenience as a detection function in which the detection function may stop due to the descent.

ムの形で制御手段６に実装する。FIG. 1 is a block diagram of a bath apparatus according to a first embodiment of the present invention, in which 1 is a bather, 2 is a bathtub, 5 is a water heater, and 3 is a water heater via a circulation port provided in the bathtub 2. 5, which is a circulation path piping connected to the internal piping of the hot water supply apparatus 5. The water heater 5 performs pouring of hot water to the bathtub 2 and additional cooking for keeping heat through the circulation path piping. Reference numeral 4 denotes a water level sensor which is an example of a water level detecting means for detecting the water level of the bathtub 2, and is installed in the circulation path pipe 3 in the water heater 5 in a normal bath device. 6
Is a control means for controlling the operation of the water heater 5, and is composed of a microcomputer and peripheral circuits. Reference numeral 8 is a kitchen remote controller for remote controlling the water heater 5, and 7 is a bathroom remote controller. The water level sensor 4 outputs a voltage signal according to the water level of the bathtub 2 and inputs it to the control means 6, and the control means 6 controls the operation of the water heater 5 based on this voltage signal, and also by the body movement detection means. It is determined whether the bather in the bathtub 2 is moving or not, and the result is displayed on the kitchen remote controller 8 or the bathroom remote controller 7. The body movement detection by the body movement detecting means can be realized by a method of comparing a signal amplitude of the water level sensor 4 or a signal amplitude obtained by filtering a signal in a predetermined frequency range from this with a preset threshold value. It is implemented in the control means 6 in the form of a program.

FIG. 2 shows an example of a graph showing the change over time in the output voltage of the water level sensor 4, and FIGS. 3 to 5 are times t4 to t5 which are the aftermath when the bather 1 exits the bath 2 in FIG.
2 is an enlarged view of the portion of FIG. 3 and is an explanatory diagram of a method of detecting the aftermath.

An increase in the output voltage indicates an increase in the water level, and a decrease in the output voltage indicates a decrease in the water level. The operation of the bather 1 in FIG. 2 is time t0 when entering the bathroom.
Shows the case where the bathtub 2 enters the bathtub 2, the body movement starts at the time t1 and the time t2 to t3, and the body moves out of the bathtub 2 at the time t4.

A periodic signal as shown at t5 is output. On the other hand, bathtub 2
It was found that when there is a bather 1 in the bath, the bather 1 himself becomes a disturbance or attenuation factor of the fluctuation of the water surface and thus the regular fluctuation of the water surface does not continue.

Since it is necessary to exclude water surface fluctuations that occur in the bathtub 1, it is necessary to specify the time when the bather 1 leaves the bathtub 2. As such a bath detection method, there has been proposed a method of determining that the bather 1 has left the bath 2 when the water level falls below the threshold width during a certain time width T.

For example, when the user stands still when trying to get out of the bathtub and becomes stuck on the edge of the bathtub, it is considered that the upper body comes out of the bathtub 2 and the water level is lowered, and the bather 1 disappears. Also, for example, when the grandchild and the grandfather take a bath together, it is determined that if the grandchild comes out first, the water level will drop at that point and there will be no bather in the bathtub 2. It is conceivable that the watching of the animals will be stopped.

It is equipped with an aftermath detector for determining whether or not. Hereinafter, based on FIGS. 3 to 5, a specific method of this aftermath detecting means will be exemplified.

Is. Vpp1 in FIG. 3 is an amplitude value in section 1, Vpp2
Is the amplitude value in section 2. Since the decay of the aftermath is delayed when there is no bather 1, a threshold value TH is set,
While the determination formula (Formula 1) is being satisfied, it can be determined that the aftermath is after the bather 1 is gone.

Then, the feature is detected. As an example of a method for observing this feature, FIG. 4 is a method for determining the periodicity of peak intervals, in which a convex peak time interval T1 and a next convex peak time interval T2 are sequentially calculated, and another threshold value TH ′.

入浴者１の安否を把握する。Based on the above, the operation of the bath apparatus of this embodiment will be described. When hot water is poured into the bathtub 2 up to a predetermined water level by the bath device, the bather 1 enters the bathroom and enters the bathtub 2 by pressing the switch for starting the watching function of the bathroom remote controller 7. In the bathtub 2, the body movement detecting means of the control means 6 detects whether or not the bather 1 is moving based on the water level fluctuation and displays the result on the kitchen remote controller 8. If there is no movement,
Counts up the duration of inanimate movement after the movement has disappeared. If the presence / absence of body movement at that time, the magnitude of the change, and the duration of inanimate movement are displayed on the kitchen remote controller 8, the situation can be grasped and it is further effective. In this situation, if a new body movement is detected, the count-up is stopped and the body movement duration time is reset to zero. If there is no body movement and the duration of inactivity continues to be counted up and exceeds the predetermined time, the kitchen remote control 8 is informed by a buzzer or the like to prompt confirmation of the safety of the bather 1, and the family responds accordingly. For example, the intercom of the kitchen remote controller 8 is used to ask the question “is it okay?” To know the safety of the bather 1.

The aftermath detection means of the control means 6 operates due to the decrease in the water level when the water comes out of the bathtub 2. At this time, if another bather remains in the bathtub 2, the aftermath detecting means determines that a variation other than the aftermath has occurred due to the body movement of the remaining bather, and the controlling means 6 Operates the body movement detecting means again to continue watching the bather who remains in the bathtub 2.

As described above, by operating the watching function at a necessary time, an effect such as power saving can be expected.

を実現することができる。As described above, according to the present invention, the movement of a person taking a bath is detected by the construction of the conventional bath device, and the kitchen remote controller or the like is informed, so that the bather can be watched over. It is possible to realize a bath device that can provide a sense of security that supports accident prevention.
