Bathroom drainage system

Abstract

To provide a bathroom drainage system that is an improvement over a conventional bathroom drainage system that cannot remove garbage inside a generator, wherein the conventional bathroom drainage system cannot remove the garbage inside the generator and restore the generator because the generator is installed in a vertical part of a drainage pipe inside a building if a situation occurs where the generator is clogged with the garbage in drainage and becomes blocked, because a bypass pipeline is provided and the drainage is previously set to flow through the bypass pipeline that bypasses the generator.SOLUTION: The interior of a chamber part can be cleaned with a water turbine removed, by providing the chamber part between a drainage port and a water drain port, housing the water turbine which is rotated by hot water flowing from the water drain port in the chamber part, providing at least one of a power generation part that generates electricity using rotational force of the water turbine and a compressor part that discharges compressed air outside the chamber part, and providing the water turbine so that the water turbine can be freely taken out from the chamber part.SELECTED DRAWING: Figure 1

Description

[Technical Field]

[0001] The present invention relates to a bathroom drainage device that recovers energy from the flow of drained water when draining hot water from a bathtub. [Background Art]

[0002] As a conventional system of this type, there is known a power generation system provided with a water turbine rotated by drainage, which is installed midway along a vertical drainage pipe that guides drainage from an upper floor to a lower floor among pipes in a building, for slowing down the speed of drainage falling inside the drainage pipe and recovering energy from the drainage (see, for example, Patent Document 1). [Prior Art Documents] [Patent Documents]

[0003] [Patent Document 1] Japanese Unexamined Patent Publication No. 2021-31918 (Figure 1) [Summary of the Invention] [Problem to be Solved by the Invention]

[0004] In the above-mentioned conventional system, since a generator is interposed in the vertical portion of a drainage pipe in a building, when a situation occurs where dust and the like in the drainage clog the generator and block the generator, the system is configured such that instead of removing dust from inside the generator, a pipe line bypassing the generator is provided in advance and drainage is set to flow through the bypass pipe line (paragraph

[0026] ), so it is not possible to remove dust from inside the generator and restore the generator to operation.

[0005] In view of the above problems, an object of the present invention is to provide a bathroom drainage device that can easily remove dust and the like and perform cleaning even if the water turbine portion provided midway along a drainage pipe is clogged with dust. [Means for Solving the Problem]

[0006] To solve the above problems, the present invention provides a bathroom drainage system in which a pipeline is provided for draining the hot water in the bathtub from the bathtub drain outlet to a drain pipe, and a drain outlet is provided in the middle of the pipeline for guiding the hot water from the floor of the bathroom washing area to the drain pipe, wherein a chamber is provided between the drain outlet and the drain outlet, a water wheel that rotates with the hot water flowing from the drain outlet is housed in the chamber, and at least one of a power generation unit that generates electricity using the rotational force of the water wheel and a compressor unit that discharges compressed air is provided on the outside of the chamber, and the water wheel is provided to be removable from the chamber so that the inside of the chamber can be cleaned with the water wheel removed.

[0007] Since the above-mentioned chamber section is located between the drain and the water outlet, it is situated inside the bathroom. Therefore, as described above, by removing the water wheel from the chamber section, it is possible to access the chamber section from inside the bathroom and clean the inside of the chamber section.

[0008] In particular, the chamber section has an opening at the top, and the waterwheel can be moved in and out through this opening. By providing a removable and watertight cover to close this opening, it is possible to prevent the water in the bathtub from coming into contact with the area around the chamber section, and thus prevent the material around the chamber section from deteriorating due to detergents and other substances contained in the water in the bathtub.

[0009] Furthermore, if the water turbine moves up and down within the chamber, it can cause abnormal noise during rotation. In such cases, the power generation unit and compressor unit are located below the chamber, the rotating shafts of these units protrude from the bottom of the chamber, the water turbine is configured to be attached to and detached from this rotating shaft from above, and the inside of the cover is provided with a retaining portion to prevent the water turbine from floating upward. [Effects of the Invention]

[0010] As is clear from the above description, the present invention can recover energy when draining the water from the bathtub. Furthermore, even if the chamber through which the water flows becomes clogged with debris, the inside of the chamber can be easily cleaned, allowing for continuous energy recovery over a long period of time. [Brief explanation of the drawing]

[0011] [Figure 1] A diagram showing the configuration of one embodiment of the present invention. [Figure 2] Longitudinal cross-sectional view showing the structure inside the chamber. [Figure 3] Cross-sectional view showing the structure inside the chamber. [Modes for carrying out the invention]

[0012] Referring to Figure 1, 1 is a bathtub, which holds hot water for bathing. When bathing is finished, the hot water is drained to the outside through a drain port 11 located at the bottom. The drained water eventually flows into a drain pipe 31, but the drain pipe 12, which is directly connected to the drain port 11, is first connected to a chamber section 21. Therefore, the hot water in the bathtub 1 flows into this chamber section 21. A drain pipe 33 is further connected to this chamber section 21, and the hot water that flows into the chamber section 21 flows through this drain pipe 33 into a drain trap 3, and then flows into the sewer (outside the figure) via the aforementioned drain pipe 31.

[0013] A screw-type lid 22 that can be opened and closed is screwed onto the upper part of the chamber section 21. Normally, the upper part of the chamber section 21 is closed, but by rotating this lid 22, it can be removed from the chamber section 21 and the chamber section 21 can be opened upwards. Normally, the drain trap 3 and the lid 22 of the chamber section 21 are separated by a cover plate 32, but as described above, when rotating the lid 22, the lid 22 can be easily rotated by removing this cover plate 32.

[0014] A compressor 23 and a generator 24 are installed below the chamber portion 21. As shown in FIG. 2 and FIG. 3, a water turbine 26 provided with rotor blades is disposed inside the chamber portion 21. The water turbine 26 is rotated by the hot water flowing in from the drainage pipe 33. The inflowing hot water flows out from the chamber portion 21 through the drainage pipe 33, so the water turbine 26 continues to rotate as long as hot water flows from the drainage pipe 12 into the chamber portion 21.

[0015] A central shaft 27 positioned at the center of the water turbine 26 is fitted via a spline structure onto a common rotating shaft 25 shared by the compressor 23 and the generator 24. This spline structure transmits rotational torque but allows the central shaft 27 to slip out upward. However, to prevent the water turbine 26 from vibrating in the vertical direction while the water turbine 26 is rotating, upward movement of the central shaft 27 is restricted by a pressing protrusion 8 provided on an inner side of the lid portion 22.

[0016] As described above, when the water turbine 26 is rotated by hot water from the bathtub 1, the compressor 23 and the generator 24 operate. Compressed air generated by the compressor 23 is temporarily stored in a tank and used for applications such as increasing the discharge pressure of a shower. Further, electric power generated by the generator 24 is stored in a capacitor or the like, and then used as a power source for lighting an emergency light or the like.

[0017] Note that the present invention is not limited to the embodiment described above, and various modifications may be made without departing from the scope of the gist of the present invention. Description of Reference Signs
