Description

[Detailed Description of the Invention] This invention mainly relates to an improved structure of a bathtub for general household use.

As for bathtubs for general households, we have seen the evolution of various materials, from traditional Japanese wooden baths, to iron Goemon baths, built-in tile baths, enamel baths, polybaths, and now stainless steel baths with decorative finishes. I've seen it. Baths made of these various materials are still selected and adopted according to each person's experience and preference, but apart from those that directly heat the bath like the Goemon bath, there are hot water heaters with circulating pot boilers as in recent years. In the case of a type bath, no matter what material the bath is made of, it is difficult to do anything about the fact that the water starts to cool from the surface of the bathtub material, so measures can be taken such as installing insulation around the outside of the bathtub to prevent cooling. However, it can be said that there have been no cases in which the inside of the bathtub, where the human body comes in contact with, has been dealt with. Therefore, when taking a bath, try to avoid touching the edge of the bathtub with your back as much as possible while swirling the water so that the warm water flows evenly around your back.
If you then put your back against the bathtub, the unwarmed temperature of the bathtub will be transferred to your back, and you will not necessarily be able to expect a comfortable bathing effect.

Therefore, in this invention, in view of the situation of the conventional bathtubs, we have developed and completed a bathtub with an improved structure as detailed below.

As can be understood from the vertical cross-sectional view of the bathtub shown in the drawings, basically in order to form a predetermined gap between the bathtub rising wall 1 and the human body back surface B, the human body back surface is located on the surface of the bathtub rising wall 1, and This bathtub is equipped with a hot water circulation device in which a protrusion or raised part 2 for partially contacting and supporting the bathtub is formed integrally with or separately from the rising wall 1 of the bathtub.

In Fig. 1, in order to show the most basic structure, an example is shown in which the protrusions or protrusions 2 are formed integrally with the rising wall 1 of the bathtub, that is, the protrusions or protrusions 2 are already formed at the bathtub forming stage. In view of not only manufacturing problems at the bathtub forming stage, but also problems in adapting to existing baths, as shown in the embodiments shown in FIGS. If realized as such, it would be even more convenient.

That is, in FIG. 2, rod-like members 21 made of a material heavier than the specific gravity of water (for example, plastic rods with embedded steel rods, etc.) 21 are connected at appropriate intervals in a "blind-like" manner, and a suction cup or hook portion 23 is attached to the top end. The figure shows an example of a bathtub that fits properly in any shape of bathtub, and that there is a predetermined gap between the upright wall 1 of the bathtub and the back of the human body B (in some cases, between the buttocks). This creates a gap that allows the warm water from the back to circulate around you while you lean back. In the case of this example, it can be rolled up and stored when not in use, it can be removed and cleaned easily when it becomes dirty due to the adhesion of scale, and above all, it can be easily stored. It has excellent advantages such as being adaptable to any type of bathtub and being able to be provided at an extremely low price.

The embodiment shown in Figure 3 is an example of a case that also serves as a storage case for a heat-retaining film on the surface of hot water. A heat insulating film 3 is attached to the axis 31 of the portion 25.
One end of the handle 32 is attached to the handle 32 so that the handle 32 can be unwound. In this example, the heat insulating film 3 is pulled out only during the stage of boiling the bath or after the bath is heated to prevent the temperature from dissipating from the surface of the water. It is stored in the back rest part 25, and this cylindrical back rest part 25 is applied to an appropriate place on the back to form a hot water circulation part between the bathtub rising wall 1 and the back surface B of the human body. . In this example, it is used as a type that can be used with other functions, but for example,
The main function is completely different, such as an underwater massage machine, and the structure to realize that structure,
Things that unavoidably result in the formation of a space on the back are not included in the technical idea of this invention, and are completely different.

In each of the above-mentioned embodiments, the structure that contacts and supports the back of the human body is a horizontally tangential structure, but the structure is not limited to these structures. It is possible to adopt various shapes and structures such as a shaped one.

As mentioned above, this device creates a space around the bathtub between the upright wall of the bathtub and the back of the bather, ensuring that warm water is always present on the back of the body. This eliminates unpleasant cold sensations from the rising walls of the bathtub or, in some cases, the bottom plate of the bathtub, making bathing extremely comfortable, especially in extremely cold regions such as the Tohoku and Hokkaido regions.

Moreover, even if it is integrated into the bathtub itself or realized as a separate body, the structure is extremely simple, so you can enjoy a comfortable bath without suffering too much economic burden. It has become possible to do so, and the effect it has is enormous.
