[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a shower apparatus provided with a hot water temperature control device having a function of suppressing sweating due to changes in temperature and stimulating human body.
[0002]
[Prior art]
As shown in FIG. 6, a shower device provided with this type of conventional hot water temperature control device provides hot and cold stimulation to a showered person by periodically supplying hot and cold water alternately. There is one that prevents acclimatization by a temperature shower bath and always provides a comfortable shower bath (for example, JP-A-5-305104). This apparatus includes a shower nozzle 1, a cold water supply unit 2 that supplies cold water to the shower nozzle 1, a hot water supply unit 3 that supplies hot water to the shower nozzle 1, a cold water supply unit 2, and a hot water supply unit 3. Is configured by an open / close control valve 4 for selectively communicating with the shower nozzle 1 and a control device 5 for controlling the open / close state of the open / close control valve 4. Then, by automatically controlling the open / close state of the open / close control valve 4 according to the open / close cycle set by the control device 5, hot water and cold water are periodically discharged from the shower nozzle 1, and the hot / cold water alternating bath is used. It became possible to give cold temperature stimulation.

[Problems to be solved by the invention]
However, the shower device provided with the conventional hot water temperature adjusting device has the following problems. (1) Sweating is a function for adjusting or lowering the body temperature of the human body. There are the following methods as an effective method for suppressing perspiration using a shower or the like. First, cold water is bathed for a predetermined time to lower the body surface temperature. Next, a shower at a temperature equal to or higher than the body temperature is taken for a predetermined time in order to return the body temperature that has been stored inside to the vicinity of the body surface due to the cold water. The body temperature returned to near the body surface by cooling water again for a predetermined time is cooled. By repeating this cold water, hot water, and cold water shower bath, the body temperature is lowered to the deep part of the human body, and effective sweating suppression becomes possible. However, in a shower device equipped with a conventional hot water temperature control device, hot water and cold water are alternately discharged from the shower nozzle 1 by the open / close control valve 4, and a sense of irritation due to the temperature difference can be obtained. Hot water may be discharged, and in this case, heat is stored inside the body due to the hot water, and sweating is further promoted, and there is a problem that sweating is not necessarily suppressed.
[0004]
(2) In a shower device equipped with a conventional hot water temperature control device , hot water and cold water having a large temperature difference are alternately discharged from the shower nozzle 1 by the open / close control valve 4, and the shower is performed while gradually acclimatizing the body to the shower temperature. There was no such thing as bathing, so there were problems such as heat shock due to sudden temperature changes.
[0005]
