Description

DETAILED DESCRIPTION OF THE INVENTION (Technical Field) The present invention relates to a bubble-generating bathtub that is used by generating fine bubbles in water at a high density.

(Background Art) Conventionally, the main method of generating bubbles in a bathtub has been to send air into a porous diffuser plate to generate bubbles. However, with this method, the diameter of the bubbles is several mm or more, the bubble rise speed in the water is fast, the water in the bathtub is stirred, and it is difficult to remove impurities, dirt, garbage, etc. in the water by flotation separation. It was hot.

In addition, in jet baths, etc., there is a method of removing dirt and the like along the path of the return water, but due to the water flow caused by the jet, impurities in the water are stirred in the bathtub and it is difficult to remove them.

(Object of the Invention) The present invention was made in view of the above points, and its object is to relate to a bubble-generating bathtub that can remove impurities, grime, dirt, etc. in the bathtub by flotation separation.

(Disclosure of the Invention) The present invention makes air bubbles fine and sends them into the bathtub, causes the air bubbles to rise without causing a water flow, and as the air bubbles rise, impurities, grime, dirt, etc. in the water are attached to the air bubbles and floated. It is separated to keep the hot water in the bathtub clean.

The present invention will be explained below based on the embodiments shown in FIGS. 1 to 4.

FIG. 1 shows an embodiment of the present invention, in which a fine bubble supply port 3 through which fine bubbles are supplied via a fine bubble generator 2 is provided at the bottom of a bathtub 1.
An overflow hole 4 as shown in FIGS. 2 and 3 is provided in the upper part.

Generation of microbubbles is performed by supplying water from the water supply port 5, creating microbubble water with the microbubble generator 2, and supplying the microbubble water into the bathtub 1 from the microbubble supply port 3. At this time, the fine bubble water supplied from the fine bubble generator 2 has a supply rate of about 5 per minute, and the flow rate is slow, so that almost no water flow occurs in the bathtub 1. Moreover, the diameter of microbubbles is 5~
Since the diameter of the bubbles is about 10 μm, the rising speed of the bubbles is slow, and almost no water flow occurs as the bubbles rise. Furthermore, since the bubble diameter is small, the surface area of the entire bubble is larger than that of large bubbles, so that impurities in water can be more efficiently attached. Since there is no water flow in the water, impurities and the like attached to the bubbles quietly rise without being stirred and are discharged from the overflow hole 4.

The overflow hole 4 may be a regular circular one, but in order to drain water more efficiently, it is preferably formed into a horizontally long slit as shown in FIGS. 2 and 3. With this configuration, impurities etc. can be smoothly and quickly discharged in large quantities.

FIG. 4 shows a different embodiment of the present invention,
A system for circulating the water in the bathtub 1 is added, and the overflow hole 4 and the water supply port 5 are connected by a circulation pipe 6, and a filter 7 for filtering impurities floated and separated is connected to the circulation pipe 6. It is characterized by being placed in the middle.

According to this embodiment, in addition to the effects of the above-described embodiments, there is an effect that hot water can be used effectively, such as saving the amount of water and saving the heat source.

(Effects of the Invention) As described above, the present invention generates fine bubbles from the lower part of the bathtub and discharges impurities etc. from the upper part to the outside of the bathtub by flotation separation. It has the advantage of simultaneously removing impurities, dirt, and grime from the body, as well as dirt from hot water. Furthermore, since microbubbles are used, water flow does not occur within the bathtub, and therefore dirt, dust, grime, etc. are not circulated within the bathtub, and are successively pushed up from the bottom to the top, allowing for efficient flotation and separation. Furthermore, since the bubbles are microscopic, the surface area of the bubbles as a whole is large, and therefore, there is an advantage that debris in the water can be efficiently removed.
