Furthermore, a waterproof small TV, an audio speaker, a bathtub with a jacuzzi, and the like may be provided.

  On the floor surface of the shower room 12, a drain port 21 for receiving drainage from the shower facility in the shower room 12 is provided. The drain port 21 is provided with a floor drain trap (not shown).

  The hot water supply unit 50 is connected to a water pipe provided in advance in the building, and heats water supplied from the water pipe with a heater using electricity or gas, and the hot water generated thereby is supplied to the shower room 12. Supply to the shower equipment inside.

  As shown in FIGS. 3 and 4, the drainage device 30 includes a drainage tank unit 31, a first drainage pump 36, a second drainage pump 37, and drainage pipes connected to the drainage pumps 36 and 37. 38.

  The drainage tank unit 31 is disposed in the pedestal unit 11 and includes a first drainage tank 32 and a second drainage tank 33 connected to the first drainage tank 32 via the communication pipe 34. . Thus, by arranging the drain tank part 31 in the pedestal part 11, enlargement of the unit type shower booth 10 by the drain tank part 31 is suppressed, and the drain tank part 31 is an appearance of the unit type shower booth 10. Will not be damaged.

  The communication pipe 34 is for overflowing the drainage in the first drainage tank 32 to the second drainage tank 33, and in the first drainage tank 33 when the operation of the first drainage pump described later is stopped. It is provided at a position higher than the water level. In the present embodiment, the first drainage tank 32 and the second drainage tank 33 are separated from each other and are connected to each other through the communication pipe 34. You may comprise by partitioning a tank with a partition wall. In this case, instead of the communication pipe 34, a communication hole is formed in the partition wall. A drainage receiving port 35 is provided on the upper surface of the first drainage tank 32.

  The drainage receiving port 35 is connected to the drainage port 21 of the shower chamber 12 by a pipe (not shown), and the drainage that has flowed to the drainage port 21 is stored in the first drainage tank 32. A dust receiver 61 is attached below the drainage receiving port 35. The dust receptacle 61 prevents foreign substances such as hair from flowing into the first drainage tank 32.

  The first drain pump 36 and the second drain pump 37 have pump bodies 36c and 37c to which suction pipes 36a and 37a and discharge pipes 36b and 37b are connected. The first drainage pump 36 is for sucking out the drainage stored in the first drainage tank 32 from the first drainage tank 32 and supplying it to the water distribution pipe 38, and the tip of the suction pipe 36 a is The discharge pipe 36 b is connected to the drain pipe 38 while being disposed in the vicinity of the bottom surface of the first drain tank 32. The second drainage pump 37 is for sucking out the wastewater stored in the second drainage tank 33 from the second drainage tank 33 and supplying the drainage pipe 38 to the water distribution pipe 38. The tip of the suction pipe 37a is The discharge pipe 37 b is connected to the drain pipe 38 while being disposed in the vicinity of the bottom surface of the second drain tank 32.

  A drainage hose (not shown) is connected to the tip of the water distribution pipe 38. The drain hose is connected to a drain pipe already provided in the building where the unit shower booth 10 is installed. The drainage hose is routed from the water distribution pipe 38 to the drainage pipe by providing an opening in a part of the flooring, passing the drainage hose under the floor from this opening, and the space between the flooring and the floor slab It can also be performed by simply drawing a drainage hose around the floor along the perimeter of the room. Since the wastewater stored in the first drainage tank 32 and the second drainage tank 33 is forcibly sent to the distribution pipe 38 by the first pump 36 and the second pump 37, respectively, the drainage hose is routed. At this time, it is not necessary to provide a gradient in the path from the water distribution pipe 38 to the drainage pipe. Therefore, the drainage hose can be routed freely.

  When connecting the drainage hose to the drainage pipe of the existing building, it is only necessary to join the drainage hose to the drainage pipe, so drainage work such as newly installing drainage pipes is unnecessary.

  A filter 62 for purifying the waste water is built in an intermediate portion between the discharge pipes 36 b and 37 b of the drain pumps 36 and 37. Each filter 62 is a cartridge type that can be freely attached to and detached from the discharge pipes 36b and 37b, and can be replaced as necessary. Gel components, bacteria, and the like that could not be removed by the above-described floor drain trap or dust receiver 61 are removed from the waste water by the filter 62 and supplied to the water distribution pipe 38 in a clean state. Therefore, the configuration is also considered for the environment.

  The first drain tank 32 is provided with a first water level sensor 41. The first water level sensor 41 includes a reference electrode 41a, an operation stop electrode 41b, an operation start electrode 41c, and an abnormality detection electrode 41d. Each electrode 41a-41d is attached to the upper surface of the 1st drainage tank 32, and is extended toward the downward direction from there. The positions of the tips (lower ends) of the electrodes 41a to 41d are different from each other, and in order from the bottom, are a reference electrode 41a, an operation stop electrode 41b, an operation start electrode 41c, and an abnormality detection electrode 41d. The positions of the lower ends of the electrodes 41 a to 41 d are lower than the position of the communication pipe 34.

  The second drain tank 33 is provided with a second water level sensor 42. The second water level sensor 42 includes a reference electrode 42a, an operation stop electrode 42b, and an operation start electrode 42c. Each electrode 42a-42c is attached to the upper surface of the 2nd drainage tank 33, and is extended toward the downward direction from there. The positions of the tips (lower ends) of the electrodes 42a to 42c are different from each other, and are, in order from the bottom, a reference electrode 42a, an operation stop electrode 42b, and an operation start electrode 41c.

  Each water level sensor 41, 42 is connected to the pump control panel 40. The pump control panel 40 includes a control unit 43 that controls the operation of the drainage pumps 36 and 37 based on the detection results of the water level sensors 41 and 42.

  In FIG. 3, the hot water supply unit 50, the drain pumps 36 and 37, and the water distribution pipe 38 are installed in the pedestal part 11 in the same manner as the drain tank part 31, but at least the drain tank part 31 is pedestal part. 11, the installation positions of the hot water supply unit 50, the drainage pumps 36 and 37, and the water pipe 38 are arbitrary.

  Next, the operation of the drainage device 30 will be described.

  Drainage from the shower facility used in the shower chamber 12 flows into the first drainage tank 32 from the drainage port 21 via the drainage receiving port 35. As for the 1st drainage tank 32, an internal water level rises with inflow of drainage. When the water level in the first drainage tank 32 reaches the lower end position of the operation start electrode 41c of the first water level sensor 41 (that is, the reference electrode 41a and the operation start electrode 41c conduct through the drainage), A signal is sent from the first water level sensor 41 to the control unit 43 of the pump control panel 40, and the first pump switch 44 is turned on. As a result, the first drain pump 36 starts operation, and the drainage in the first drainage tank 32 is sent to the drainage pipe of the building via the drainage pipe 38 and the drainage hose.

  When the inflow amount of the wastewater into the first drainage tank 32 is smaller than the discharge amount of the first drainage pump 36, the water level in the first drainage tank 32 gradually decreases. And the water level in the 1st drainage tank 32 falls to the lower end position of the operation stop electrode 41b of the 1st water level sensor 41 (namely, although the reference electrode 41a and the operation start electrode 41c are not conducted, When the reference electrode 41a and the operation stop electrode 41b are in a conductive state via drainage), a signal is sent from the first water level sensor 41 to the control unit 43 of the pump control panel 40. As a result, the first pump switch 44 is turned off, and the operation of the first drain pump 36 is stopped.

  Thereafter, the above-described operation is repeated until the shower facility in the shower room 12 is used.

  Here, when the inflow amount of the wastewater into the first drainage tank 32 is larger than the discharge amount of the first drainage pump 36, the water level in the first drainage tank 32 gradually rises. In addition, when the first drain pump 36 fails or when a malfunction occurs in the operation start electrode 41c and the continuity between the reference electrode 41a and the operation start electrode 41c cannot be obtained, the first drain pump Since the pump 36 does not operate, the water level in the first drainage tank 32 gradually rises with the inflow of drainage into the first drainage layer 32.

  The first water level sensor 41 may further include an operation start spare electrode (not shown). The operation start spare electrode is installed such that its lower end position is located between the operation start electrode 41c and the abnormality detection electrode 41d. When the first water level sensor 41 has the operation start spare electrode, the water level in the first drainage tank 32 reaches the lower end position of the operation start spare electrode (that is, the reference electrode 41 and the operation start electrode). When the auxiliary electrode is in a conductive state), a signal is sent from the first water level sensor 41 to the control unit 43 of the pump control panel 40. Thereby, when the cause of the rise in the water level of the first drainage tank 32 is due to the malfunction of the operation start electrode 41c, the first drainage pump 36 operates and the water level in the first drainage tank 32 decreases. I will do it. On the other hand, when the cause of the rise in the water level of the first drainage tank 32 is due to the malfunction of the first drainage pump 32, the first drainage pump 32 does not operate and the water level rises as it is.

  When the water level in the first drainage tank 32 further rises and reaches the lower end position of the abnormality detection electrode 41d, a signal is sent from the first water level sensor 41 to the control unit 43 of the pump control plate 40. As a result, an alarm is issued from an alarm device (not shown), and informs the user and / or manager that a malfunction has occurred in the unit shower booth 10. A user who knows that a problem has occurred informs the administrator that the problem has occurred. Alternatively, an administrator who knows that a problem has occurred takes measures necessary to recover the problem, such as requesting a repair from the manufacturer. The user and / or the administrator can stop the operation of the alarm device.

  On the other hand, the unit type shower booth 10 can continue to operate even after a failure occurs. That is, when the water level in the first drainage tank 32 further rises and reaches the position of the communication pipe 34, the drainage in the first drainage tank 32 flows into the second drainage tank 33 via the communication pipe 34. To do.

  The water level in the second drainage tank 33 rises and reaches the lower end position of the operation start electrode 42c of the second water level sensor 42 (that is, the reference electrode 42a and the operation start electrode 42c are conducted through the drainage). ) And a signal is sent from the second water level sensor 42 to the control unit 43 of the pump control panel 40. As a result, the second pump switch 45 is turned on, and the operation of the second drainage pump 37 is started. The drainage in the second drainage tank 33 is drained in the building via the drainage pipe 38 and the drainage hose. Water is sent to the service pipe.

  The water level in the second drainage tank 33 is lowered by the operation of the second drainage pump 37, and the internal water level is lowered to the height of the operation stop electrode 42b of the second water level sensor 42 (that is, the reference electrode 42a and When the operation start electrode 42c is not conductive, the reference electrode 42a and the operation stop electrode 42b are connected through drainage), and a signal is sent from the second water level sensor 42 to the pump control panel. It is sent to 40 control units 43. As a result, the second pump switch 45 is turned off, and the operation of the second drain pump 37 is stopped.

  In this way, even when a failure occurs in the first drain pump 36, drainage by the second drain pump 37 is possible. Therefore, the unit type shower booth 10 can be continuously operated using the second drainage tank 33 and the second drainage pump 37 as a backup until the first drainage pump 36 recovers.

  Furthermore, since the drainage capacity of the first drain pump 36 and the second drain pump 37 can be made smaller than the maximum drainage expected, the first drain pump 36 and the second drain pump 37 can be downsized. And power consumption can be reduced.

  As mentioned above, although the drainage apparatus was demonstrated to the unit type shower booth about this invention, the drainage apparatus of this invention is installed in the existing building, The drainage apparatus for various facilities which can produce drainage Can be used as Examples of facilities that can generate drainage include washing machines, retrofitting sinks, retrofitting washstands, and the like.
