Description

DETAILED DESCRIPTION OF THE INVENTION (Technical Field) The present invention relates to a bubble-generating bathtub in which bubbles can be mixed.

(Background Art) It is known that mixing air bubbles into a bathtub has the effect of cleaning the body surface and promoting blood circulation compared to normal bathing. FIG. 1 shows a conventional example of a bathtub equipped with this type of bubble generation mechanism, in which air bubbles are generated in the bathtub 1 by ventilating a porous plate 2 placed in the bathtub 1 via an air pump 3. This is how it was done.

However, in such conventional methods, the diameter of the bubbles is 1 mm or more, making it difficult to form fine bubbles. In addition, in the case of bubbles with such a bubble diameter,
Because the bubble diameter is large, the rising speed is fast, making it difficult to keep a large amount of air bubbles in the bathtub.Also, because the rising speed is fast, water flows inside the bathtub, making the temperature feel lower than that of still water even at the same water temperature. There was a problem with the price being high.

(Object of the invention) The present invention has been made in view of the above problems, and
The purpose is to provide a bathtub in which the perceived temperature can be controlled without changing the temperature of the water during bathing.

(Disclosure of invention) Hereinafter, the present invention will be explained based on examples.

FIG. 2 shows an embodiment of the present invention, in which a linear nozzle 4 is provided at the center of the bottom of the bathtub 1 so as to divide the bathtub 1 into two. Air bubbles are generated by the air supplied by the air pump 3. Also, bathtub 1
A suction port 6 and a discharge port 7 connected to a microbubble generating device 5 are provided on the side of the container, and microbubble water is discharged from the discharge port 7.

By the way, as mentioned above, in conventional bubble-generating bathtubs, the bubbles are large and when the bubbles rise, a water flow is generated, which tends to raise the perceived temperature compared to still water.
Experiments have confirmed that the perceived temperature is lower than that of still water due to the insulation effect of air bubbles. Therefore, as in the above embodiment, the nozzle 4
By dividing the bathtub 1 in half at the center by the air bubbles coming out, one bathtub 1 can be partially divided into two parts: still water and fine bubble water. In other words, as mentioned above, one bathtub 1 can be divided into two parts: a part where the water temperature feels high and a part where it feels low. (who prefer hot water) and children (who prefer warm water) can bathe together at the water temperature of their choice.

In addition, since the above embodiment includes devices for generating two types of bubbles, it is also possible to operate only one of them. Therefore, as shown in FIG. 4, there is a fine bubble bath in which only the fine bubble generator 5 is operated, a normal bubble bath in which only the air pump 3 is operated as shown in FIG. 3, and a normal bubble bath in which only the air pump 3 is operated as shown in FIG. 5, and neither is operated as shown in FIG. Four types of bathing are possible: a bubble-free bath and a separate bath as shown in FIG.

In this way, the method of changing the perceived temperature by incorporating air bubbles does not take much time and is effective as soon as air bubbles are generated, but the conventional method of raising and lowering the water temperature does not change the water temperature instantly. Not only was this not possible, but the main methods required a heat source or lowered the temperature of the water using water, which was wasteful in terms of energy and was expensive.

Further, in the separate bath shown in FIG. 2, parent and child bathing is possible, but the following bathing is also possible.
First of all, when you first start taking a bath, your body is not used to bathing, so take a fine bubble bath as shown in Figure 4 at a slightly lower temperature, and as you get used to it, stop the bubbles and soak in still water as shown in Figure 5. Take a bath. Furthermore, near the end of bathing, a normal bubble bath as shown in FIG. 3 can be used to warm up well. Micro-bubble baths are also effective for people with sensitive skin, including those with red skin and women.

(Effect of the invention) As described above, the bubble generating bathtub according to the present invention has the following features:
A nozzle linearly arranged in the center of the bottom of the bathtub, an air pump that supplies air to the nozzle, and an inlet and an outlet respectively arranged on one side of the bathtub divided into two by the nozzle. and a fine bubble generating device connected to the suction port and the discharge port and discharging fine bubble water from the discharge port. Since the bathtub can be divided into two parts using air bubbles, it is possible to separate one bathtub into two parts with different sensible temperatures without changing the water temperature, and by using two bubble generation mechanisms, you can freely and instantly It has become possible to change the sensible temperature.
