Description

Description: TECHNICAL FIELD The present invention relates to a bathtub overflow structure for overflowing hot water supplied into a bathtub.

[Conventional technology]

Large bathtubs provided in hotels, recreational facilities, etc. clean the inside of the bathtubs by constantly circulating and filtering supplied hot water and overflowing. However, in a large tub without a circulation filter, the replenished hot water overflows from the upper part of the side wall, so that relatively hot water in the tub flows out, and low-temperature water stays in the lower part of the tub. . In order to avoid this, it is necessary to increase the temperature of the supplied hot water, so that the heat source capacity must be increased, which causes an increase in cost.

[Problems to be solved by the invention]

An object of the present invention is to provide a bathtub overflow structure that stores high-temperature water supplied into a bathtub and allows low-temperature water to overflow in consideration of the above fact.

[Means for solving the problem]

The present invention provides a bathtub overflow structure in which hot water supplied into a bathtub provided with a drain port on the bottom wall overflows from the upper end of the side wall lowered from the surroundings, wherein a lower end is provided with a gap between the bottom wall and the upper end. Is characterized in that a bathtub is partitioned by an inner wall located above the side wall, and an auxiliary path for guiding hot water below the bathtub to an upper end of the side wall is provided between the partition and the side wall.

In addition, a lower edge is formed in the inner wall at substantially the same level as the upper end of the side wall, and a lid for sealing the opening is provided.

Further, the lid is rotatably attached to the inner wall, and when the opening is opened, an upper opening of the auxiliary path is closed.

Further, a notch is formed by partially cutting down the upper end of the side wall and the upper end of the inner wall, and an adjusting plate is attached to any of the notches, and the upper end of the adjusting plate is at the same level as the upper end of the side wall or the inner wall. It is characterized in that it is at the same level as the upper end.

In the present invention, hot water stored in the bathtub is completely drained from the drain port by pulling out a plug or the like fitted to the drain port. When the drain port is closed with a stopper and hot water is supplied into the bathtub, the water level rises and reaches the upper end of the side wall.

However, the hot water in the upper part of the bathtub is blocked by the inner wall and cannot overflow from the upper end of the side wall. On the other hand, the hot water in the lower part of the bathtub overflows from the upper end of the side wall and is drained through an auxiliary path formed between the side wall and the inner wall. Thereby, the high-temperature water in the upper part of the bathtub is stored, and the low-temperature water in the lower part of the bathtub is drained, so that the temperature of the hot water in the bathtub can be raised efficiently.

Also, by forming an opening in the inner wall and making the lower edge of this opening substantially the same level as the upper end of the side wall, dirt and dust floating in the bathtub are discharged from the upper end of the side wall through the opening. You. If the opening is closed with the lid, the low-temperature water in the lower part of the bathtub will be drained again.

Furthermore, when the lid is rotatably attached to the inner wall, when the opening is opened, the upper opening of the auxiliary path is closed by the lid, so that the low-temperature water at the lower part of the bathtub is not drained, and dirt from the opening is removed. Emission efficiency is improved.

In addition, a notch is formed by cutting down the upper end of the side wall and the upper end of the inner wall, and an adjusting plate is selectively mounted in the notch. For example, if an adjusting plate is attached to the notch in the side wall, the upper end of the adjusting plate is at the same level as the upper end of the side wall, so that the water level in the bathtub rises to the height of the side wall, and the dust floating in the bathtub from the upper end of the side wall. And dust are discharged.

On the other hand, if the adjusting plate is attached to the cutout of the inner wall, the upper end of the adjusting plate is at the same level as the upper end of the inner wall, so that the low-temperature water at the lower part of the bathtub is drained through the auxiliary passage.

(Example of the invention)

FIG. 1 shows a bathtub 10 to which a first embodiment of the present invention is applied. In the bathtub 10, the side wall 1 extends from around the bottom wall 10A.
0B is erected so that hot water supply from the supply pipe 12 is stored.

The upper end portion 10C of the side wall 10B is an overflow portion of the stored hot water 14, and a predetermined amount of hot water always overflows by the hot water supply from the supply pipe 12.

Inside the side wall 10B, an inner wall 16 parallel to the side wall 10B is provided. The inner wall 16 forms an auxiliary path 18 with the inside of the side wall 10B, and the lower end 18A of the auxiliary path 18 opens to the lower part in the bathtub 10. The upper end of the inner wall 16 projects further upward than the upper end of the side wall 10B.
A substantially L-shaped guide portion 22 extending outward is fixedly attached. Therefore, the upper end 18B of the auxiliary path 18 guides the low-temperature water in the lower part of the bathtub led from the lower end 18A to the upper end of the side wall 10B to overflow from the side wall 10B (in the direction of arrow B).

The inner wall 16 is formed over the entire area of the side wall 10B in the direction perpendicular to the plane of FIG.

In the present embodiment configured as above, the high-temperature water supplied from the supply pipe 12 into the bathtub 10 stays at a relatively upper portion, and the low-temperature water stays at a relatively lower portion. When the water level reaches the upper end of the side wall 10B, the low-temperature water near the bottom in the bathtub 10 is guided from the lower end 18A to the auxiliary path 18, and overflows from the upper end of the side wall 10B. In this case overflow water is bathtub
Since the water is guided from the relatively lower part of the bathtub 10, the low-temperature water at the lower part of the bathtub 10 will overflow sequentially, and the bathtub 10
The upper part inside stores hot water. In addition, the hot water supplied from the supply pipe 12 circulates in the bathtub 10 as shown by a broken line in FIG. 1, so that the cleanliness in the bathtub 10 is maintained.

FIG. 2 shows a second embodiment of the present invention. In this embodiment, an adjustment plate 32 is pivotally supported on the side of the inner wall 16 facing the side wall 10B. The adjusting plate 32 closes an open opening 34 formed at the upper end of the inner wall 16, so that a pin 36 protrudes from a part of the adjusting plate 32, and a rotating lever is attached to the tip of the pin 36. 38 are supported. The rotation lever 38 is rotatable around the rotation axis S, and is partially closed on the inner peripheral edge of the opening 34 and closed in the state shown in FIG. Has become. In order to seal the gap between the opening 34 and the adjusting plate 32 in this closed state, flexible packings 42 and 44 are respectively attached to the outer peripheral surface of the inner wall 16 and the surface facing the adjusting plate 32.

The adjusting plate 32 is rotated in the direction of arrow A from an upright position as shown by the imaginary line in FIG. 2 so that the tip end thereof comes into contact with the upper end of the side wall 10B. In this state, the height of the side wall 10B is raised substantially by the thickness of the adjustment plate 32. The upper end of the inner wall 16 is at the same height as the side wall 10B. The packing 45 provided on the adjustment plate 32 contacts the side wall 10B while the adjustment plate 32 contacts the upper end of the side wall 10B.

For this reason, in this embodiment, when the adjusting plate 32 closes the opening 34 as shown by a solid line in FIG. 2, the auxiliary path 18 guides low-temperature water from the lower part of the bathtub 10 as in the first embodiment. It is possible to overflow from the upper end of the side wall 10B (arrow B direction).

Also, the engagement of the rotating lever 38 with the opening 34 is released, and the adjusting plate
If 32 is in a flat state as shown by the imaginary line in FIG.
The upper end of the auxiliary path 18 is closed, the opening 34 is opened, and the height of the side wall 10B is increased substantially by the thickness of the adjusting plate 32. For this reason, the water level in the bathtub 10 rises, and the stored hot water 14 in the upper part passes through the opening 34 and gets over the adjusting plate 32, thereby overflowing. For this reason, dirt and dust floating on the surface of the storage hot water 14 can be discharged.

Next, FIG. 3 shows a third embodiment of the present invention.
In this embodiment, an adjusting plate 52 is used in place of the adjusting plate 32 in the above embodiment. A notch 54 is formed at the upper end of the side wall 10B so as to correspond to the upper end of the auxiliary path 18.
The height is partially reduced. A notch 56 is also formed at the upper end of the inner wall 16 so that the height of this portion is the same level as the notch 54.

The adjustment plate 52 can be selectively attached to the notches 54 and 56 in the directions of arrows C and D. Therefore, a substantially U-shaped receiving portion 52A is formed around the adjustment plate 52, and the notch 54 or the notch 56 is formed.
It is supported over the.

For this reason, in this embodiment, if the adjusting plate 52 is attached to the notch 56, the height of the inner wall 16 becomes the same level as the maximum height of the side wall 10B.
Overflowed from 54. Also cut out this adjustment plate 52
If it is removed from 56 and attached to the notch 54, the notch 54 will be closed, so the height of the side wall 10B will be high throughout the entire area, the water level will rise to the upper end 10C, and the dirt and dust floating on the storage hot water 14 will overflow. Can be done.
