Description

  The present invention relates to a mist shower bath apparatus using hot water mist that can be bathed outside a bathroom with a small amount of hot water used.

Conventionally, a warm bubble bathing booth apparatus that is advantageous for enhancing the bathing effect is known. This hot bubble bathing booth device includes a booth having a storage space where a user enters, a hot bubble discharge unit provided in the booth for discharging hot bubbles into the storage space, and a hot bubble discharge unit provided in the booth. The warm bubble supply unit is configured to discharge the warm bubble toward the vicinity of the shoulder of the user who has entered the accommodation space.
The warm foam used here is a foam composed of large bubbles using a foaming agent. For this reason, after bathing with warm foam, it is necessary to wash away the foam adhering to the user's body and the foam remaining in the accommodation space, and a large amount of hot water is used. Therefore, this booth device needs to be provided in the bathroom.

  However, bathing in the bathroom may cause problems (so-called heat shock) such as fluctuations in blood pressure due to rapid temperature changes for the weak. In addition, since the foaming agent contained in the hot foam is soap or body soap, the oil content is lost too much for the bather, which may cause rough skin.

If you can bathe in the living room, problems such as fluctuations in blood pressure due to such rapid temperature changes will not occur.
If a hot water shower mixed with nanobubbles is used, the cleaning effect of the body can be exhibited without using a detergent such as soap because of the high detergency of the nanobubbles. Further, a sufficient cleaning effect can be obtained with a smaller amount of hot water than usual. Since it is not necessary to use a surface active agent such as soap, oil is not washed away from the body more than necessary. If a mist shower with hot water is used, a high bathing effect can be obtained with a very small amount of hot water.
If the amount of hot water to be used can be reduced, it can be used by storing a necessary amount of water or hot water in a tank without being connected to a water tap or hot water tap, and can also be used in a living room outside the bathroom.
