[Means for solving the problem] A water pump that sucks in and pressurizes the hot water in the bathtub,
In this hot water circulation type bubble generator equipped with a nozzle for spouting the water delivered from the lift pump into the bathtub, the structure of the nozzle of the lift pump is such that the hot water spouted from the nozzle is spouted into the hot water in the bathtub. When bathing, air is introduced into the hot water in the bathtub as fine bubbles, and a bath agent containing polyethylene glycol is mixed in, which foams fine bubbles with the air introduced into the circulating hot water in the bathtub. It is characterized by [Effect] When an appropriate amount of a bath agent containing polyethylene glycol, which foams fine bubbles by the air introduced into the circulating hot water in the bathtub, is added to hot water, the properties of the above bath agent and the bubbles of the water in the circulating bath work together. hand,
Many layers of fine air bubbles appear on the water surface of the bathtub. These large numbers of bubbles burst and break instantly, and the ultrasonic waves generated at that time affect the bather's body, producing heat, massage, and cleaning effects. [Embodiment] The figure is a structural diagram of an apparatus according to an embodiment of the present invention. This device includes a pump 1 that sucks hot water in a bathtub 3 from a pumping pipe 2 and pressurizes it, and a nozzle 5 that spouts water sent from the pump 1 into the bathtub.
The structure of the nozzle 5 of the water pump 1 is such that when the hot water ejected from the nozzle 5 is ejected into the hot water in the bathtub, air is introduced into the hot water in the bathtub by fine air bubbles 6.
It is characterized by mixing a bath agent containing polyethylene glycol, which is set to such an extent that it is introduced into the hot water circulating in the bathtub, and which foams fine bubbles with the air introduced into the hot water circulating in the bathtub. That is, in the present invention, when a bath agent containing polyethylene glycol that foams fine bubbles by the air introduced into the circulating hot water of the prior application device is mixed, a layer of fine bubbles 6 is generated on the hot water surface 4a. Such bath additives may contain polyethylene glycol and sodium hydrogen carbonate, or may contain polyethylene glycol, sodium hydrogen carbonate, and anhydrous sodium sulfate, and may further contain polyethylene glycol and anhydrous sodium sulfate. You may. Such bath preparations may also contain trace amounts of pigments, fragrances, or pigments and fragrances. In such bath preparations, sodium hydrogen carbonate is 10 to 55% by weight, and anhydrous sodium sulfate is 5 to 5% by weight.
45% by weight, and pigments and fragrances can be blended within the range of 0.001 to 3.0% by weight. In this example, sodium bicarbonate is used as the carbonate, and anhydrous sodium sulfate is used as the sulfate. Further, as the pigment, one that is highly safe for the human body is appropriately selected from various types of pigments, and as the fragrance, one that is highly safe for the human body is appropriately selected and used. The bath additive of the present invention will be explained below. The bath preparation of the present invention, which contains foaming polyethylene glycol that is hydrophilic and generates fine bubbles when air is introduced into hot water, is Although no bubbling phenomenon is observed, the bubbling phenomenon appears prominently in the bathtub where a bubble generator equipped with the nozzle 5 and which violently jets out hot water is in operation. That is, when a fixed amount of the bath agent according to the present invention is poured into a bathtub with jets ejected from the nozzle 5, the properties of the bath agent and the bubbles in the hot water act to form a layer of fine bubbles 6 over the hot water surface 4a. is formed. Such bath additives generate fine bubbles, have good foaming properties, and are easy to break (the surface elasticity of the bubbles is weak), which increases the ultrasonic stimulation transmitted to the bather's skin. These many microscopic bubbles burst and crack instantly,
The ultrasonic waves generated at that time act on the bather, increasing the effects of heat, massage, and cleaning compared to when only the bubble generator was used. Next, various tests were conducted on the bath preparation of the present invention, which is an orange powder with a faint aroma, as follows. (Confirmation test) (1) This product exhibits a yellow color in a pale reaction (sodium salt). (2) Take a small amount of this product in a test tube, pour 2 to 3 ml of pre-chilled dilute hydrochloric acid into it, and when gently heated, notice the evolution of gas.
