  The present invention relates to a bathing management system capable of managing the time a bather is immersed in a bathtub.

  For example, an electrocardiogram signal of a bather immersed in a bathtub is detected by an electrode installed in the bathtub, and digitized heart rate data such as a heart rate is created based on the detected electrocardiogram signal of the bather. An electrocardiogram information notification system for displaying this on the display unit has been proposed, and when such an electrocardiogram information notification system is adopted, a bather who has a cardiac dysfunction or the like can display a heart rate displayed on the display unit. Since it is possible to accurately grasp changes in the state of the heart based on heart rate data such as numbers, it is possible to get out of the bathtub before the burden on the body increases.

Japanese Patent Laid-Open No. 5-95921

  By the way, the elderly and those who are accustomed to taking a hot bath generally have a dull thermal sensation, and bathers with a healthy thermal sensation are warm enough to get out of the bathtub. People who have a dull thermal sensation, even in a state that they want to have, have a tendency to bathe without having a desire for bathing. Therefore, in the case of a person who has such a dull thermal sensation, it is desirable to measure the bathing timing in accordance with his / her heart rate data notified by the electrocardiogram information notification system as described above.

  However, as described above, when a person with a low thermal sensation measures the bathing timing according to his / her heart rate data notified by the electrocardiogram information notification system, the satisfaction of sufficiently warming is not obtained. Since bathing has to be performed, the heart rate data reported by the electrocardiogram information notification system is neglected and long bath is used, and there is a problem that it is difficult to improve the effect.

  Accordingly, an object of the present invention is to provide a bathing management system that can arouse the bather's desire to take a bath when the burden on the body is expected to increase during bathing.

  In order to solve the above-described problems, the invention according to claim 1 includes a biological information measuring device that measures biological information of a bather, a variable color illumination device that illuminates the bathroom, and / or a variable color illumination device that illuminates the interior of the bathtub. When the bather continues to take a bath as it is from the bather's biological information measured by the biological information measuring device, if the burden on the body is expected to increase, the hue of illumination by the variable color illumination device is changed. The present invention provides a bathing management system comprising a hue adjusting device that changes in a warm color direction.

  According to a second aspect of the present invention, there is provided an electrocardiogram information measuring device for measuring electrocardiogram information of a bather, a variable color illumination device for illuminating a bathroom, and / or a variable color illumination device for illuminating a bathtub, and the electrocardiogram. Provided with a bathing management system, comprising: a hue adjusting device that changes the hue of illumination by the variable color lighting device in a warm color direction as the heart rate of the bather measured by the information measuring device increases. To do.

  Further, the invention according to claim 3 is the invention according to claim 2, wherein the heart rate of the bather is increased even if a predetermined time has elapsed after the electrocardiogram information measurement apparatus starts measuring the electrocardiogram information. When the rate does not reach a predetermined rate of increase, the hue adjusting device changes the hue of illumination by the variable color lighting device in the warm color direction.

  The invention according to claim 4 is the invention according to claim 1, 2, or 3, wherein the hue adjusting device is caused to input the hot water temperature in the bathtub, and the input hot water temperature in the bathtub is taken into consideration. Thus, the hue of illumination by the variable color illumination device is changed in the warm color direction.

  The invention according to claim 5 is the invention according to claim 1, 2, 3 or 4, wherein the hue adjusting device is made to input the age of the bather in advance, and the entered bather's age is entered. In consideration of age, the hue of illumination by the variable color illumination device is changed in the warm color direction.

  As described above, in the bathing management system according to the first aspect of the present invention, from the bather's biological information measured by the biological information measuring device, if the bather continues bathing as it is, the burden on the body is expected to increase. In this case, since the hue adjustment device changes the hue of the illumination by the variable color lighting device in the warm color direction, the bather can warm up directly from the hot water in the bathtub in contact with the body. Not only do you feel warm, but you will also feel warm because of the psychological effects of the colors of the lights that illuminate the interior of the bathroom and the bathtub, and you will be fully warmed before the burden on your body increases. If you get a sense of satisfaction, you will bathe on your own. Therefore, even for bathers who have a dull thermal sensation, such as elderly people or people who are accustomed to taking hot baths, it is possible to prevent the occurrence of unforeseen circumstances such as falling without bathing and taking a bath. can do.

  In addition, as in the bathing management system according to the second aspect of the invention, as the bather's heart rate measured by the electrocardiogram information measuring device increases, the hue of illumination by the variable color lighting device is changed in the warm color direction. If you do this, you will be able to bathe voluntarily by gaining the satisfaction that the bather is fully warmed before the burden on the body, which can be regarded as an increase in heart rate, increases. It is effective not only for bathers who have a dull thermal sensation, but also for bathers with cardiovascular disorders.

  Also, since the physical burden associated with bathing may not appear as an increase in heart rate, the electrocardiogram information measurement device starts measuring electrocardiogram information as in the bathing management system according to the third aspect of the invention. After that, if the rate of increase of the heart rate of the bather does not reach the predetermined rate of increase even after the predetermined time has elapsed, the hue of illumination by the variable color illumination device is changed in the warm color direction, It is possible to prevent the bather from bathing longer than necessary.

  In particular, like the bathing management system of the invention according to claim 4, the hue of the illumination by the variable color lighting device is changed in the warm color direction in consideration of the hot water temperature in the bathtub, or the invention according to claim 5 When bathing age is high, if the color of the lighting by the variable color lighting device is changed in the warm color direction, taking into account the bather's age, as in the bathing management system of Furthermore, since the hue of illumination by the variable color illumination device can be changed in the warm color direction early, the occurrence of a shortage can be prevented beforehand.
