Description

[Detailed Description of the Invention] This invention relates to a means for heating bath water from the lower layer during bathing in a bathtub.

In conventional boiler hot water bathtubs, hot water is discharged directly from the hot water tap 1 in FIG. 2 through the space to the upper surface of the bath.
Constant stirring is necessary to heat the lower layer of bath water. The hot bath water cools down as soon as the hot water supply is turned off, so when you are taking a bath in an old kettle bath, the heat slowly warms up from the bottom of your body, and your body stays warm for a while after you finish the bath, making you sweaty. The disadvantage of not being able to feel the sensation is especially noticeable in winter.

This invention aims to eliminate the above-mentioned drawbacks by simple means.

To explain the mat of this invention based on the drawing, hot water sent from the boiler is transferred from the induction hose 2 connected to the hot water tap above the bathtub (Fig. 2) to the mat 6.
Hot water is discharged downward at right angles to the center of the bottom surface of the bathtub from a hot water outlet 4 through a pipe 3 attached to the lower surface. The discharged hot water is guided by the legs 5 attached radially on the bottom surface of the mat 6 and is evenly spread in all directions along the bottom surface of the bathtub. This hot water further rises evenly through the gap between the mat 6 and the bathtub 7 in FIG. As a result, the temperature during bathing can be adjusted by adjusting the hot water tap 1 only once during bathing.
The bath can always be slowly raised from the bottom, making it easy to adjust the bathing time and desired temperature to each person's bathing time.

As mentioned above, this idea allows hot water to slowly rise from the bottom layer around the bathtub while you are taking a bath, allowing you to fully enjoy the feeling of an old-fashioned kettle bath and gushing hot springs. Therefore, except for catching a cold, bathing is extremely beneficial for health.

In addition, with conventional hot water supply methods, hot water discharged from the hot water faucet loses a lot of heat due to the space up to the bath hot water surface and the agitation required to bring the temperature of the bath hot water surface to the lower layer, but with this idea, the loss of heat is extremely small. It is characterized by having the economical effect of a heat source because only a small amount of hot water is required.
