Description

Description: TECHNICAL FIELD The present invention relates to a bathtub device for returning hot water drawn out from a bathtub by a pump to a bathtub, and more particularly, to installing a bathtub on a floor pan to provide a bath floor. The present invention relates to a technique for avoiding water from flowing to a drive mechanism in a bathtub device while avoiding water leakage to the bathtub device, thereby improving the workability thereof.

[Prior Art] Conventionally, in a bathtub apparatus for returning hot water drawn out from a bathtub by a pump to a bathtub, a drive mechanism such as a pump is installed near the bathtub at a location different from the bathtub. .

[Problems to be Solved by the Invention] However, when the driving mechanism such as a pump is installed separately from the bathtub, the mutual mounting positions are shifted, and it is difficult to perform a good mutual mounting relationship. There was a problem.

The present invention has been made in view of such a problem, and an object of the present invention is to install a bathtub on a floor pan and effectively use a configuration that avoids water leakage to the bathroom ground. It is an object of the present invention to provide a bathtub device capable of suppressing mutual displacement with a drive mechanism, making a good connection between the two, and preventing water from reaching the drive mechanism in particular.

[Means for Solving the Problems] The bathtub apparatus of the present invention is a bathtub apparatus for returning hot water drawn out from a bathtub 1 by a pump 2 to a bathtub 1, and includes a washing place 3b.
Forming a high step portion 4 on the floor pan 3 forming a series of
A ventilation hole 7 is formed in the step portion 4, a cylindrical cover 10 is attached across the ventilation hole 7, a substrate 12 is provided at a position higher than the step portion 4 at the bottom of the cover 10, and the pump 2 is mounted on the substrate 12. It is mounted, and the cover 10 is provided with a lid 19 for inspection.

[Action] As described above, the floor pan 3 which forms the washing area 3b in a series.
To form a high step portion 4 ', and to form a vent hole 7 in the step portion 4,
A tubular cover 10 is attached across the ventilation hole 7, and a substrate 12 is provided at a position higher than the step 4 at the bottom of the cover 10.
The pump 2 is placed on the floor 10 and a cover 19 for inspection is provided on the cover 10 so that the inside of the cover 10 straddling the ventilation hole 7 formed on the high step 4 formed on the floor pan 3 is higher than the high step 4. The pump 2 is mounted on a substrate 12 provided at a higher position, so that hot and cold water flowing through the floor pan 3 is not transmitted to the pump 2, and when the pump 2 is operated, hot air is supplied to the vent hole 7.
From the pump 2, the environment around the pump 2 can be suitably maintained, and the inspection can be performed by opening the inspection port lid 19 formed on the cover 10.

Examples Examples of the present invention will be described below in detail with reference to the drawings.

The accompanying drawings show an example of a bathroom unitized, that is, a bathroom unit, FIG. 1 is a perspective view of the bathroom unit, FIG. 2 is a vertical sectional view, and FIG.
The figure shows a plan sectional view, and in such a bathtub 1,
Hot water drawn out of the bathtub 1 by the pump 2 is returned to the bathtub 1 in the form of a waterfall, or a bubble bath specification is used in which bubbles are returned together with air bubbles. It is a bathtub device that can be used as a bath.

The floor pan 3 of the bathroom unit is composed of a bath tub placement part 3a and a washing place part 3b.
By dividing the floor pan 3 in this way, the installation of the bathtub 1 and the construction of the pipeline thereof can be easily performed. The bathtub mounting part 3a and the washing place 3b are connected with a sufficient sealing property. In the figure, reference numeral 22 denotes a drain hole, and 23 denotes a mounting portion on which the bathtub 1 is mounted, which is reinforced with plywood.

The bathtub 1 is formed in a substantially fan shape in which a portion along a wall 6 at a corner of the bathroom is linear. A step portion 4 which is higher than this is formed near the bathtub mounting portion 3a of the floor pan 3 on which the bathtub 1 is mounted. A drive mechanism 5 such as the pump 2 is mounted on the step 4. Hereinafter, the configuration will be described in detail.

As shown in FIG. 5, a ventilation hole 7 is formed in the step portion 4 so that hot air can be discharged downward. Vent 7
A reinforcing plywood 8 is stretched on the lower surface side of the peripheral portion to reinforce. A packing 9 is laid on the upper surface of the peripheral part of the ventilation hole 7, and a rectangular tube-shaped cover 10 is attached with screws 11. A substrate 12 is attached to the bottom of the cover 10 with bolts 13, and the circulation pump 2 is mounted on the substrate 12. Introductory part on cover 10
A return pipe 15 and a return section 15 are formed. The introduction section 14 is connected to an introduction pipe from the bathtub 1, and the return section 15 is connected to a return pipe to the bathtub 1. Then, the hot water from the bathtub 1 is sucked from the bathtub 1 through the inlet pipe, and the hot water is returned from the return pipe 15 to the bathtub 1 through the return section 15 through, for example, a filtration section or a sterilization section. I can do it. When returning to the bathtub 1 as described above, bubbles may be mixed by an ejector action so that a bubble bath specification can be made. Then, a pipe 16 for detecting the presence or absence of hot water in the bathtub 1 is led out of the bathtub 1, and this pipe 16 is connected to a connection portion 17 formed on the cover 10, and a pressure provided inside the connection portion 17. A switch (not shown) detects the presence or absence of hot water and a state below a certain water level, and based on the detection result, can perform control such that the operation of the pump 2 is stopped. A jet-type waterproof pump (not shown) is mounted on the inner part 4a of the step part 4. It is possible to control to switch to a jet bath specification in which hot and cold water is sucked, air bubbles are mixed therein, and the jet is strongly jetted and returned. Such control can be performed by a switching handle provided on the flange of the bathtub 1. The control circuit and electronic components are housed in a control section 18 in the cover 10.

The upper end of the cover 10 is opened, and the lid 19 is
It is detachable by operation so that maintenance and inspection of the inside can be performed. A counter 21 above the lid 19
Is detachably provided, and the lid 19 can be removed by removing the counter 21.

In this way, the floor pan 3 on which the bathtub 1 is placed avoids water leakage to the bathroom ground, and the drive mechanism 5 such as the bathtub 1 and the pump 2 are both installed on the floor pan 3. Thus, the mutual displacement of the bathtub 1 and the drive mechanism 5 is eliminated, so that the connection between the bathtub 1 and the drive mechanism 5 can be performed satisfactorily and easily with little displacement. In such a case, the driving mechanism 5
Is placed on the raised step portion 4 to prevent the water from flowing to the drive mechanism portion 5.

[Effects of the Invention] In summary, the present invention forms a high step in a floor pan forming a series of washing places, forms a vent in the step, and attaches a cylindrical cover across the vent. At the bottom of the cover, a substrate is provided at a position higher than the step, a pump is placed on the substrate, and a cover for inspection is provided on the cover, so the cover that straddles the ventilation hole formed at the high step of the floor pan Inside, the pump is placed on a substrate provided at a position higher than the high step, so that hot water running down the floor pan does not transfer to the pump, and when the pump is operated, hot air is released. There is an advantage that the air can be discharged from the vent hole, the environment around the pump can be suitably maintained, and the inspection can be performed by opening a lid of an inspection port formed in the cover.
