  Hereinafter, with reference to an accompanying drawing, the composition of the rail system for rail vehicles and the toilet system for rail vehicles concerning this embodiment is explained in detail. In the following, a filth tank and a water tank are listed as various tanks provided in a purification unit which is an example of a tank system, but the present invention can also be applied to tanks used for similar purposes such as a sewage tank.

  FIG. 1 is a diagram showing a configuration of a railway vehicle toilet system 1000 according to the present embodiment. As shown in FIG. 1, the toilet system 1000 is provided in a toilet room on a railcar floor, and includes a purification unit 100, a toilet 200, and a hand-washer 300.

  The purification unit 100 is a unit used for purification processing of filth and sewage (hereinafter, excrement) performed in the toilet system and control of processing associated with the processing. As shown in FIG. 1, the purification unit 100 is configured as a tank system having a control panel 101 as a control unit, a water tank 102 as a first tank, and a waste tank 103 as a second tank. ing.

  The control panel 101 is a controller having a microprocessor that receives power from a power supply unit (not shown), which is a power supply unit provided in the railway vehicle, and controls various operations of the purification unit 100. For example, the control panel 101 stores a program for controlling an electromagnetic valve that switches between supply and discharge of air that expands and contracts an air cylinder (not shown) for generating a vacuum, and executes the program to thereby create a toilet system. The operation of each part constituting 1000 is controlled. The control panel 101 is installed in a space (for example, a gap between each tank and the frame) of a rack constituted by a frame 201 described later.

  The water tank 102 is a tank for storing water, which is an example of a cleaning liquid for flowing excrement stored in the toilet bowl 200, and is physically connected to the toilet bowl 200 by a pipe R1 that is a first pipe. The The pipe R1 is, for example, a pipe that forms a flow path for flowing the water from the water tank 102 to the toilet bowl 200. Control of the control panel 101 controls the amount of liquid used by the water tank 102, the timing of flowing the liquid via the pipe R1, and the like. In the following, water is exemplified as the cleaning liquid. However, the present invention is not limited to this. For example, the control panel 101 includes water stored in the water tank 102 and cleaning water stored in a detergent tank (not shown). A detergent may be mixed and flowed through the pipe R1.

  The filth tank 103 is a tank for storing excrement discharged from the toilet 200, and is physically connected to the toilet 200 by a pipe R2 which is a second pipe. The pipe R <b> 2 is a pipe that forms a flow path for allowing the excrement to flow from the toilet 200 to the filth tank 103, for example. The control timing of the control panel 101 controls the transfer timing of excrement to the filth tank 103 and the like.

  The toilet bowl 200 is a container having a bowl for receiving excrement, and is physically connected to the water tank 102 by the pipe R1 and physically connected to the waste tank 103 by the pipe R2. The toilet bowl 200 has a first piping port that is a piping port connected to the piping R1 and a second piping port that is a piping port connected to the piping R2. In the toilet bowl 200, when the excrement in the bowl is flowed, the control panel 101 generates a vacuum to reduce the pressure in a transfer tank (not shown) provided in the pipe R2 to a negative pressure. The control panel 101 performs control such as closing both the discharge valve and the transfer valve provided upstream and downstream of the transfer tank, and evacuating the transfer tank.

  The hand-washing device 300 is a device in which a user who has excreted excrement wash hands, and is physically connected to the water tank 102 by a pipe R3 which is a third pipe. The hand-washing machine 300 has a third piping port that is a piping port connected to the piping R3. The pipe R3 is, for example, a pipe that forms a flow path for flowing the water from the water tank 102 to the hand washing device 300. Control of the control panel 101 controls the amount of liquid used by the hand-washing machine 300, the timing of flowing the liquid, and the like. As for the liquid used by the hand washing machine, water stored in the water tank 102 and detergent for hand washing stored in a detergent tank (not shown) may be mixed and flowed through the pipe R3.

  As shown in FIG. 1, the purification unit 100 is provided on an upper floor T1 of the vehicle T. For this reason, sufficient space can be ensured in the space of the floor lower part T2 of the vehicle T in which devices necessary for traveling such as the drive unit M and the wheels W are arranged. Specifically, it is possible to secure a space SP1 in which a water tank among various tanks is conventionally provided and a space SP2 in which a waste tank is provided.

  As described above, the control by the control panel 101 is vacuum control, and conventionally, excrement has been flowed by sucking water from the water tank 102 installed under the floor and pumping and processing it. However, by providing the purification unit 100 including the water tank 102 on the floor as in the present embodiment, water can flow from the water tank 102 by gravity, and landing control from under the floor becomes unnecessary. For this reason, the power consumption for processing excrement can be suppressed.

  Further, in this embodiment, as shown in FIGS. 1 and 2, the filth tank 103 and the toilet bowl 200 of the purification unit 100 are disposed adjacent to each other on the same surface on the floor, and both are connected by a pipe R2 for control. The excrement is pumped by the control of the panel 101. Therefore, power consumption can be suppressed as compared with landing control from under the floor, and, for example, between the toilet 200 and the floor surface of the toilet in the connection surface S (see FIG. 2) of the purification unit 100 with the toilet 200. The space X can be provided with a gap X and held and fixed to the frame 201 described later. Thereby, since the toilet bowl 200 can be comprised as a wall-hanging type toilet bowl, the floor structure of the toilet room can be simplified, the floor surface of the toilet room can be easily cleaned, and a comfortable toilet space can be maintained. In addition, since the on-floor structure other than the purification unit 100 can be substantially shared between the vehicle with a toilet and the vehicle without a toilet, the vehicle design cost can be reduced.

  Furthermore, in the present embodiment, the water tank 102 has a laminated structure in which the water tank 102 is placed on the filth tank 103, so that the water supply to the toilet 200 via the pipe R1 can be a water pressure by gravity, and from below the floor. No landing control is required, and power consumption by the landing control can be suppressed.

  As described above, according to the present embodiment, it is possible to secure a larger space under the floor of the railway vehicle than in the past, and therefore electrical equipment such as a power storage mechanism for supplying a drive device such as a motor and power to the space. Can be installed. In addition to the above-described effects, troublesome work under the floor for installing the toilet system 1000 can be reduced, which can contribute to a reduction in vehicle manufacturing costs.

  FIG. 2 is an external perspective view of the purification unit 100. As shown in FIG. 2, the purification unit 100 includes a control panel 101, a water tank 102, a waste tank 103 shown in FIG. 1, a frame 201 serving as a housing for integrating them, and pipes 202 </ b> A and 202 </ b> B. And a ventilation fan 203. Each part of the purification unit 100, that is, the control panel 101, the water tank 102, the waste tank 103, the pipes 202A and 202B, and the ventilation fan 203 are detachably held and fixed to the frame 201 by fasteners such as screws (not shown). . As described above, the toilet 200 is physically connected with the gap X between the lower surface of the toilet 200 and the floor of the toilet.

  The frame 201 is a frame for configuring each part of the purification unit 100 as one unit, and is, for example, a rack made of a highly rigid material. The size of the frame 201 is substantially the same as the size when the water tank 102 and the waste tank 103 are overlapped. For example, when the depth of the recess is deeper than the diameter of the pipe and the frame 201 is completely in each tank, the frame 201 has the same width as the horizontal length (depth) of each tank.

  The pipe 202 is the pipe R1 shown in FIG. 1, and FIG. 2 shows two pipes connected to the water tank 102 constituting the purification unit 100 as an example. Specific configurations of the piping, the water tank 102, and the filth tank 103 in the purification unit 100 will be described later.

  The ventilation fan 203 is a fan for ventilating the toilet room in which the toilet system 1000 is installed. The ventilation fan 203 is operated at a predetermined timing in accordance with an instruction from the control panel 101.

  Although specific shapes and materials of the water tank 102 and the filth tank 103 will be described later, these tanks are connected to pipes (in FIG. 2, pipes 202A in order to secure passenger space on the floor). , 202B) is provided with a recess for disposing. Although the case where the depth of the said recessed part is deeper than the diameter of piping is illustrated below, the depth of the said recessed part may be shallower than the diameter of piping. Even in this case, it is possible to achieve a compact configuration in which the length (depth) of each tank in the horizontal direction is shortened as compared with the related art at the portion entering each tank.

  In the present embodiment, the purification unit 100 is installed on the floor, and the frame 201 is configured as a unit in which the water tank 102, the filth tank 103, and the control panel 101 are integrated. It becomes easy and the vehicle manufacturing cost can be suppressed. Moreover, since the water tank 102, the filth tank 103, and the control panel 101 which comprise the purification | cleaning unit 100 are each detachable independently, when maintaining each part, it can replace | exchange independently and a toilet Easy maintenance can be realized while maintaining a compact system configuration.

  In the conventional toilet system, the control panel 101, the water tank 102, the filth tank 103, and the like are arranged separately, and not only the space under the floor but also the space above the floor in the toilet is pressed. By consolidating and unitizing, a surplus space can be created both under the floor and above the floor, and even a small space in the toilet can be used efficiently. Moreover, since the water tank 102 is unitized as a laminated structure superimposed on the filth tank 103, for example, a pipe between the toilet bowl 200 and the water tank 102, a pipe between the toilet bowl 200 and the filth tank 103, Arrangement can be simplified, and each tank is concentrated in one unitized place, so that the length of the pipe itself is shorter than the conventional toilet system where each tank is arranged separately. It is possible to provide a compact toilet system.

  FIG. 3 is a top view showing the relationship between the water tank 102, the filth tank 103, and these pipes. As shown in FIG. 3, in the water tank 102 and the filth tank 103, the recessed part for arrange | positioning piping is formed. As shown in FIG. 3, the horizontal length (depth) W of each tank in FIG. It is possible to make a compact configuration that is shorter than the above. For this reason, more passenger living space on the floor can be secured as compared with the case where the tank is provided on the floor as it is. Further, even when it is not necessary to secure a large passenger living space, the space in the longitudinal direction of the toilet room P can be widened, so that a more comfortable toilet room space can be provided compared to the conventional case.

  Furthermore, by providing the recesses in the water tank 102 and the filth tank 103, the rigidity of these tanks can be increased, and even when the lateral length is shortened, the structure is stable without being easily deformed. It has become.

  The water tank 102 and the filth tank 103 are made of polyethylene (PE) as a material. Therefore, the weight can be reduced as compared with these conventional tanks, and the weight of the railway vehicle in which the toilet system is installed can be reduced. In addition, since these tanks are made of polyethylene, the molds of these tanks can be manufactured at a lower cost than when made of plastic such as FRP resin or metal such as stainless steel.

  FIG. 4 is a diagram showing examples of the shapes of the water tank 102 and the filth tank 103 shown in FIG. As shown in FIG. 4, the water tank 102 and the filth tank 103 are formed with recesses at positions where pipes are arranged. At least one concave portion is provided on each surface, but when a certain rigidity can be ensured, one or more concave portions may be provided on at least one surface. In FIG. 4, a recess 401, a recess 402, and a recess 40n are provided. Although FIG. 4 illustrates the case where the concave portion is provided on the surface in the horizontal direction, it may be provided on a surface different from the horizontal direction (for example, a side surface in the vertical direction in FIG. 4). The greater the number of recesses formed in each tank, the higher the rigidity can be obtained. Next, more specific configurations of the water tank 102, the filth tank 103, and the piping will be described.

  FIG. 5 is a diagram showing a specific shape of the water tank 102 shown in FIGS. FIG. 5 shows a top view (a) of the water tank 102, a front view (b) of the toilet tank side of the water tank 102, and a side view (c) of the water tank 102, respectively. FIG. 6 is a front perspective view of the water tank 102 shown in FIG.

  In FIGS. 5 and 6, pipes 501 to 504 and a water level meter 505 are provided in the water tank 102 in which the above-described concave portion which is the first concave portion is formed. The pipe 501 is, for example, one of the pipes R1 shown in FIG. 1 and is a pipe for pouring water into the water tank 102 from the supply source. The pipe 502 is, for example, one of the pipes R1 shown in FIG. 1 and is a pipe for discharging the water that is supplied to the water tank 102 and becomes full of water to the outside. The pipe 503 is, for example, one of the pipes R <b> 1 illustrated in FIG. 1 and is a pipe for performing air bleeding from the water tank 102. The pipe 504 is one of the pipes R1 shown in FIG. 1 and is a pipe for supplying water to the toilet bowl 200. The water level meter 505 is a sensor for measuring the remaining amount of water stored in the water tank 102, for example.

  As already described, the water tank 102 is formed with the recess (represented by the recess 40n in FIG. 5A), and the various pipes are arranged corresponding to the position of the recess. Recognize.

  FIG. 7 is a diagram showing a specific shape of the waste tank 103 shown in FIGS. FIG. 7 shows a top view (a) of the filth tank 103, a front view (b) on the toilet room side of the filth tank 103, and a side view (c) of the filth tank 103, respectively. 8 is a front perspective view of the filth tank 103 shown in FIG. 7 on the toilet room side.

  In FIGS. 7 and 8, pipes 701 to 704 and a full water sensor 705 are provided in the filth tank 103 in which the concave portion, which is the second concave portion, is formed. The pipe 701 is, for example, one of the pipes R <b> 2 shown in FIG. 1, and is a pipe for sending excrement pumped from the toilet 200 to the filth tank 103. The pipe 702 is, for example, one of the pipes R <b> 2 shown in FIG. 1 and is a pipe for discharging the sewage that has become full in the filth tank 103 to the outside. The pipe 703 is, for example, one of the pipes R <b> 2 illustrated in FIG. 1 and is a pipe for cleaning the inside of the filth tank 103. The pipe 704 is one of the pipes R2 shown in FIG. 1 and is a pipe for transferring excrement stored in the filth tank 103 to an external storage tank. The full water sensor 705 is a sensor for measuring the amount of sewage stored in the filth tank 103, for example.

  As already described, the filth tank 103 is formed with the concave portion (represented by the concave portion 40n in FIG. 7A), and the various pipes are arranged corresponding to the position of the concave portion. Recognize.

  The water tank 102 shown in FIGS. 5 and 6 and the filth tank 103 shown in FIGS. 7 and 8 have the same shape made from a common mold, and the pipes necessary for each tank are located at different positions. It arrange | positions in the said recessed part formed. For example, the pipe 501 used in the water tank 102 is disposed in the recess 40x, and the pipe 703 used in the filth tank 103 is disposed in the recess 40y that is a recess adjacent to the recess 40x. When the water tank 102 is overlaid on the filth tank 103, no pipe is arranged in the recess 40x on the filth tank 103 side formed at a position on the filth tank 103 corresponding to the pipe 501 used in the water tank 102. The recess 40x is designed so that the pipe 501 used in the water tank 102 can pass through. Therefore, even when the water tank 102 and the filth tank 103 are overlapped, the same pipe 501 can be disposed in these recesses across the recesses 40x on the water tank 102 side and the filth tank 103 side. In addition, the piping route to the toilet bowl 200 is the shortest, and the simple purification unit 100 can be configured.

  Further, for example, when the water tank 102 is overlaid on the filth tank 103, no pipe is arranged in the recess 40y formed at a position on the water tank 102 corresponding to the pipe 703 used in the filth tank 103. . However, even in such a case, the rigidity of the water tank 102 itself can be increased by the recess 40y formed on the water tank 102 side. Moreover, piping used for other uses, such as tanks other than the water tank 102 and the waste tank 103, can be arrange | positioned at the said recessed part 40y. Similarly, in FIG. 5 (a), no pipe is arranged in the recess 40n on the water tank 102 side, which is the same position when the water tank 102 and the waste tank 103 are overlapped, but in FIG. 8 (a). A pipe 702 is disposed in the recess 40n on the filth tank 103 side.

  In this way, the water tank 102 and the filth tank 103 have the same shape, and when the water tank 102 and the filth tank 103 are overlapped, the concave portion 40x of the water tank 102 is changed to the filth tank 103 corresponding to the concave portion 40x. A pipe 501 reaching the recess 40x is arranged, in other words, a configuration in which one common pipe passes through the recess having the same position in the overlapping direction when the water tank 102 and the waste tank 103 are overlapped. Therefore, the piping path when the tanks are stacked while maintaining the strength of the tank can be minimized, and a simple purification unit 100 can be configured. Further, the water tank 102 and the filth tank 103 can be manufactured from a single mold, and each tank can be manufactured at low cost. Furthermore, since the water tank 102 and the filth tank 103 are made from the same mold, the water tank 102 can be reused as the filth tank 103 or the filth tank 103 can be reused as the water tank 102.

  FIG. 9 is a diagram illustrating a state in which the water tank 102 and the waste tank 103 are overlapped to form a unit. As shown in FIG. 9, the pipe 501 of the water tank 102 is arranged in the recess 40 x of the water tank 102, and the pipe 501 arranged at this position is when the water tank 102 and the filth tank 103 are overlapped with each other. Are disposed so as to pass through the recess 40x of the filth tank 103 provided at the same position. Therefore, the pipe 501 can be configured as one pipe extending vertically downward from the water tank 102 to the waste tank 103, and the length of the pipe (in this case, the length from the water tank 102 to the toilet bowl 200). ) Can be shortened, and the cost for piping can be reduced. The same applies to other pipes such as the pipe 502 and the pipe 503.

  As described above, the present embodiment has been described with reference to the drawings. However, the present embodiment is not limited to the above-described embodiment as it is, and may be embodied by modifying constituent elements without departing from the scope of the invention in the implementation stage. A plurality of constituent elements disclosed in the embodiment can be implemented in appropriate combination. For example, in the above embodiment, the pipes used in the water tank 102 and the filth tank 103 are arranged on the unit surface on the toilet room side and the opposite surface on the opposite side. It is good also as a structure which arrange | positions some piping in the provided recessed part.

  The control panel 101 is supplied with power from the power supply unit of the railway vehicle and controls each part. The battery for supplying power to the purification unit 100 to each part of the toilet system 1000 and the purification unit 100. It is good also as carrying. For example, the control panel 101 determines whether or not the supply of electric power from the railway vehicle has been interrupted due to a disaster such as a power failure, and if it is determined that the supply of electric power from the railway vehicle has been interrupted, it is necessary to operate the toilet system 1000 by itself. The power supply source may be switched from the power supply unit to the battery, power may be supplied to each part such as the control panel 101, and control may be continued. For example, as shown in FIG. 2, a battery B electrically connected to the control panel 101 or the like is provided in the space below the filth tank 103 in the purification unit 100, and the supply of electric power from the battery B is received. The control panel 101 may continue control of each part of the toilet system 1000 and the purification unit 100. As described above, when the battery B is provided in the purification unit 100 constituting the toilet system 1000, power is not supplied from the railway vehicle due to a disaster such as a power failure while maintaining a compact configuration as the toilet system. However, each part of the toilet system 1000 and the purification unit 100 can be controlled.
