Description

The present invention relates to a bathroom structure.

In recent years, various facilities for assisting persons requiring assistance such as persons with disabilities and the elderly have been installed in houses and various facilities. As one of them, there is known a bathroom in which a bath board and a transfer table are provided and the relative position between the bathtub and the bath board and the transfer table can be changed according to the physical characteristics of the person requiring assistance and the bathing operation. ..

For example, Patent Document 1 discloses a bathroom structure including at least two bath boards arranged in a non-arranged portion of a bathtub on a bathtub arrangement floor. Patent Document 2 discloses a bathroom structure having a slide rail installed on a floor for bathtub arrangement, a lateral movement base mounted on the slide rail, and a bathtub mounting portion attached to the lateral movement base. .. In the bathroom structure described in Patent Document 2, if the lower end of the bathtub is placed on the bathtub mounting portion, the bathtub can be moved along the slide rail.

Further, for example, in Patent Document 3, a leg portion to which a low friction material is attached to the tip is provided in the bathtub, and the bathtub is freely arranged at substantially the center and the end portion on the floor for bathtub arrangement. The bathroom structure is disclosed. For example, in Patent Document 4, a long length that is formed so as to extend along the longitudinal direction of the bathtub and the legs of the bathtub are slidably placed so that the bathtub can be slidably moved in the longitudinal direction.

However, in the conventional bathroom structure and mobile bathtub, a moving mechanism such as legs and wheels is attached to the bottom surface of the bathtub body to make the bathtub movable, and the bottom surface of the bathtub body is separated from the reference surface of the bathroom. There was a risk that the stability of the bathtub body would decrease. In addition, if the bottom surface of the bathtub body is to be brought closer to the reference pan floor surface with the moving mechanism attached to the bottom surface of the bathtub body, the bathtub pan floor surface must be lower than the reference surface, and the bathtub pan floor surface must be lowered. It became difficult to secure the slope of the drainage ditch formed in the water, and there was a risk that the drainage efficiency of hot water would decrease.

The present invention has been made in view of the above circumstances, and provides a bathroom structure capable of stably moving a bathtub and ensuring drainage efficiency of hot water in a bathtub.

The bathroom structure of the present invention includes a bathtub and a bathtub support portion in which the bathtub is arranged so as to be movable in a predetermined movement direction, and the bathtub includes a bathtub body having a hot water reservoir recess and the bathtub body. It is provided with wheels that are connected and provided on the outside of the hot water reservoir recess in the moving direction, and the bathtub support portion is formed with a recess in which the wheels can be detachably accommodated.
In the above-mentioned bathroom structure, since the wheels are located outside the hot water reservoir recess in the moving direction, the height of the bottom surface of the bathtub body is made closer to the height of the reference surface of the bathroom as compared with the case where the bottom surface of the bathtub body has a moving mechanism. The bathtub can be stabilized and easily moved along the moving direction. Further, in the above-mentioned bathroom structure, since the bottom surface of the bathtub body and the facing surface of the bathtub support portion are close to each other, most of the height difference allowed in the bathroom structure can be used for the height difference of the drainage groove. Can take a sufficient gradient. As a result, the drainage efficiency of hot water in the bathtub can be ensured. If there are wheels on the bottom of the bathtub body and the bathtub pan floor with the bathtub support is lowered below the surrounding pan floor, most of the height difference allowed in the bathroom structure will be the bathtub pan floor. Will be used as an offset to lower from the surrounding pan floor. Then, the slope of the drainage ditch for guiding the hot water discharged from the hot water reservoir recess to the drainage pipe outside the bathroom structure cannot be sufficiently taken.

The bathroom structure of the present invention includes a bathtub pan floor surface having the bathtub support portion and a washroom pan floor surface adjacent to the bathtub pan floor surface, and the heights of the bathtub pan floor surface and the washroom pan floor surface. The difference may be 0 mm or more and 5 mm or less.
In the above-mentioned bathroom structure, the difference in height between the bathtub pan floor surface and the washing place pan floor surface is 0 mm or more and 5 mm or less, so that the bathtub pan floor surface is higher than the washing place pan floor surface as in the conventional bathroom structure. The transfer table, etc. can be installed directly on the floor of the bathtub pan, even if there is no side board for installing the transfer table, etc. Therefore, it is not necessary to provide a sideboard, and sideboardless can be realized.

In the bathroom structure of the present invention, a bathtub drainage port is provided on the outer peripheral edge of the bottom surface of the hot water reservoir recess, and the size of the bathtub drainage port in the moving direction is larger than the size of the bathtub drainage port in the height direction. A first drainage groove facing the bathtub drainage port and extending along the moving direction is formed on the bathtub pan floor surface or the washing place pan floor surface, and the first drainage groove is formed on the bathtub pan floor surface. A second drainage ditch that extends so as to communicate with the drainage ditch and the bathroom drainage port leading to the outside of the bathroom may be formed.
In the above-mentioned bathroom structure, since the longitudinal direction of the bathtub drainage port is along the extending direction of the first drainage ditch, the amount of hot water discharged from the bathtub drainage port to the first drainage ditch increases per unit time. At the same time, the hot water discharged from the bathtub drainage port is less likely to overflow from the first drainage ditch. Further, even if the bathtub drainage port moves to an arbitrary position in the moving direction as the bathtub moves, the hot water discharged from the bathtub drainage port flows into the first drainage ditch facing the bathtub drainage port and drains the bathroom. Guided by the mouth. As a result, the hot water discharged from the bathtub drain port can be smoothly guided to the bathroom drain port and drained to the outside of the bathroom, so that the drainage efficiency of the hot water can be improved. Further, in the above-mentioned bathroom structure, hot water and water droplets on the floor of the bathtub pan can be collected in the second drainage ditch, guided to the bathroom drainage port, and drained to the outside of the bathroom.

In the bathroom structure of the present invention, the bathtub is connected to the bathtub body, further provided with auxiliary ribs lower than the bottom surface of the hot water reservoir recess, and extends to the bathtub support portion along the moving direction. A guide groove may be formed in which at least a part of the auxiliary rib is accommodated.
In the bathroom structure described above, the bathtub moves on the bathtub support portion with at least a part of the auxiliary ribs housed in the guide groove, so that the wheels and the bathtub are less likely to deviate from the moving path.

According to the bathroom structure of the present invention, the bathtub can be moved stably, and the drainage efficiency of hot water in the bathtub can be ensured.
