Description

  The present invention relates to a mobile toilet device (portable toilet), and more specifically, for example, a flush toilet device used by an elderly person or a sick person who needs to be used in a place other than a toilet space, and It relates to the drainage system.

  Conventionally, a toilet device is installed in a toilet space that has been designed and constructed in advance, and an appropriate drainage pipe slope, caliber, etc. are determined depending on the location of the toilet space. It was configured to discharge into the sewage system. On the other hand, a mobile toilet device has been proposed in order to cope with elderly people, sick people, and the like who need to be used in places other than the toilet space.

  As such a mobile toilet device, the applicant of the present invention has proposed various types of pumping sewage to a sewage system in order to cope with a place where an appropriate slope of a drain pipe is not secured. In addition, in order to respond to the need to reduce the diameter of drainage horizontal branch pipes for sanitary equipment such as toilets, wastewater from sanitary equipment such as toilets is transported by a small-diameter drainage horizontal branch pipe, and the drainage is further discharged. A drainage pipe joint and a drainage system configured to flow into a vertical pipe have also been proposed (see, for example, Patent Document 1).

JP 2002-88841 A

  By the way, when installing this mobile toilet apparatus in places other than toilet space, in order to drain sewage, it is necessary to provide a new drainage system. However, since it takes a considerable amount of time or a considerable period to construct a drainage system like that, the user cannot use the mobile toilet device for a long time, and the construction cost increases. There was a problem.

  Then, the present inventors examined connecting the drainage pipe of a mobile toilet apparatus to the drainage channel of the existing hand-washing part attached to the building frame, such as a wall, and repeated the experiment by an actual machine. However, when the drainage pipe of the mobile toilet device is connected to the existing drainage channel, even if the connection position is downstream of the drainage trap, the trap water is lost due to the drainage of the mobile toilet, In some cases, it was found that odors rose to the hand-washing section.

  Therefore, in the present invention, it is made in view of such circumstances, it is possible to greatly simplify the construction method as compared with the prior art, it is possible to reduce the construction time and construction cost, An object of the present invention is to provide a mobile toilet device that contributes to the convenience of the user and does not allow odors to flow into the room.

  In order to solve the above-mentioned problems, a mobile toilet apparatus according to the present invention includes (1) a bowl portion that receives filth, and a drainage flow that discharges cleaning water supplied to the bowl portion as sewage from the bowl portion together with filth. A toilet body having a path; (2) a water supply unit that supplies the wash water to the bowl portion; a sewage storage unit that stores the sewage discharged from a drainage flow path of the toilet body; and (3) the sewage And a sewage discharge unit having a drainage pipe for discharging the sewage in the sewage storage unit from the sewage storage unit. An end portion of the drain pipe is connected to a downstream side of a drain trap formed or provided in a drain flow path of a hand-washing section provided in a building frame where the mobile toilet device is installed. The mobile toilet apparatus according to the present invention further includes (4) a drainage amount setting means for setting the drainage amount of the sewage drained into the drainage pipe to a drainage amount corresponding to the pipe diameter of the drainage channel of the hand-washing unit.

  In the mobile toilet apparatus configured as described above, the sewage in the sewage storage unit is conveyed and discharged to the outside through the drain pipe by the sewage discharge unit. The end of this drainage pipe is connected to the drainage channel of the hand-washing part installed in a place other than the toilet space where the mobile toilet device is installed (patient room, bedroom, living room, etc.). Sewage is discharged into the drainage channel of the hand-washing section. Also, a drain trap is formed or provided in the drain channel of the hand wash section, and the end of the drain pipe is connected to the downstream side of the drain trap, so that the sewage odor moves to the hand wash section side. Leaking from there is deterred.

  By the way, the drain trap is to prevent the odor from moving to the hand-washing part side by forming a sealed water, so if the sewage flowing from the drain pipe connected to the downstream side of the drain trap flows backward. The sealed water is replaced by sewage, and the sewage odor may shift to the hand-washing part. Therefore, in the present invention, paying attention to the fact that the pipe diameter of the drainage channel of the hand-washing section is actually different, the drainage amount of the sewage drained into the drainage pipe is the amount of drainage corresponding to the pipe diameter of the drainage channel of the hand-washing section. The waste water amount setting means is provided. In this way, by setting the amount of sewage drainage corresponding to the pipe diameter of the drainage channel of the hand washing part, it is possible to suppress the inflow of sewage exceeding the drainage capacity of the drainage channel of the hand washing part, and to the drain trap side Can be suppressed.

  Further, in the mobile toilet apparatus according to the present invention, the drainage amount setting means changes the output of the pumping means for pumping the sewage, thereby changing the drainage amount of the sewage to a drainage amount corresponding to the pipe diameter of the drainage channel. It is also preferable to do.

  In this preferred embodiment, since the amount of wastewater discharged is adjusted by changing the output for pumping the wastewater, the amount of wastewater corresponding to the pipe diameter of the drainage flow path of the hand-washing section can be adjusted reliably and quickly.

  The mobile toilet apparatus according to the present invention further includes an operation unit that receives an operation instruction for at least one of the toilet body and the sewage discharge unit, and the drainage amount setting unit is based on the operation instruction input to the operation unit. It is also preferable that the amount of wastewater discharged is set to a drainage amount corresponding to the pipe diameter of the drainage channel.

  In this preferred embodiment, since the amount of drainage is adjusted based on the operation instruction input to the operation unit, the user operates after confirming the pipe diameter of the connection destination when installing, and the drainage flow of the hand-washing unit It is possible to reliably adjust the amount of drainage suitable for the pipe diameter of the road.

  In the mobile toilet apparatus according to the present invention, the operation unit includes an input operation unit and an input notation unit that describes operation instruction contents corresponding to the input operation unit. By performing a back operation instruction that is not performed on the input operation unit, the drainage amount setting means sets the drainage amount of the sewage to a drainage amount corresponding to the pipe diameter of the drainage channel based on the back operation instruction. Is also preferable.

  In this preferred embodiment, by performing a back operation instruction not indicated in the input notation section, the drainage amount setting means sets the drainage amount of sewage to the drainage amount corresponding to the pipe diameter of the drainage channel, so that the user can instruct the back operation. Therefore, the possibility of performing the operation by mistake is reduced.

  According to the present invention, the end of the drainage pipe of the sewage discharge unit is connected to the drainage flow path of the existing hand-washing unit attached to the place where the mobile toilet device is installed, and sewage flows from there to the sewage system. Since it is discharged, it becomes unnecessary to construct and install a new drainage system as in the prior art. Thereby, compared with the case where a drainage system is newly installed, the construction time and construction cost of a mobile toilet apparatus can be reduced significantly, and it becomes possible to improve a user's convenience markedly. Furthermore, by setting the amount of drainage corresponding to the pipe diameter of the drainage channel, it is possible to prevent sewage from flowing back through the drainage channel and replacing the sealed water of the drainage trap provided on the hand-washing part side. However, the odor can be prevented from spreading into the room even if it does not have an odor prevention function.

Further, the dimensional ratio is not limited to the illustrated ratio. Furthermore, the following embodiment is an illustration for explaining the present invention, and is not intended to limit the present invention only to the embodiment. Furthermore, the present invention can be variously modified without departing from the gist thereof.

  FIG. 1 is a perspective view showing a preferred embodiment of a mobile toilet apparatus according to the present invention (partially, a piping diagram shown in isometric projection), and FIG. 2 is a movement shown in FIG. Fig. 3 is a system configuration diagram schematically showing the configuration of the toilet device, and Fig. 3 is a schematic sectional view schematically showing a part of the mobile toilet device shown in Fig. 1.

  As shown in these figures, the mobile toilet apparatus 10 is a portable type (portable type) that can be installed in, for example, a living room space R (a space in which a user such as a hospital room, bedroom, or living room lives). A toilet body 1 is provided. The toilet body 1 includes a bowl portion 11 formed with a concave surface for temporarily receiving dirt such as defecation and wiping paper and urine (manure), and a bent tubular shape from below the bottom portion of the bowl portion 11 so as to communicate with the bowl portion 11. The drainage flow path 12 extends in the direction.

  The toilet body 1 is connected to a water supply unit 2 for supplying cleaning water to the bowl unit 11. The water supply unit 2 is provided with an on-off valve such as an electromagnetic valve for supplying and stopping the supply of cleaning water. Here, the cleaning water supply method to the toilet body 1 is not particularly limited, and can be appropriately selected according to the installation state and the installation location of the toilet body 1. For example, a tank is provided as the water supply unit 2, and the tank The stored wash water may be flowed to the bowl portion 11 of the toilet body 1, or directly connected to the water supply on the side of the building cabinet, supplied with water as wash water, and the bowl portion 11 of the toilet body 1. You may comprise so that it may flow. Thus, as the water supply unit 2, any means for supplying cleaning water to the toilet body 1 can be adopted.

  Moreover, the drainage flow path 12 is extended outside, for example from the back surface of the toilet bowl main body 1, and is connected to the sewage storage part 3 which has the tank-shaped space for storing the sewage W, for example. The connection end of the drainage channel 12 is open to the internal space of the sewage reservoir 3, and for example, a frappe valve for opening and closing the opening may be provided. Further, the sewage storage unit 3 is provided with a ventilation valve 31 and an airbag 32. The vent valve 31 is a valve that is opened only when the sewage W is allowed to flow and can take air into the internal space of the sewage reservoir 3 and the drainage passage communicating therewith, and is closed immediately thereafter. It does not restrict | limit in particular, For example, a Dorgo ventilation valve etc. are mentioned. Moreover, the airbag 32 is for adjusting the pressure in the internal space of the sewage storage part 3, and the waste_water | drain path | route connected to it.

  Further, in order to measure the water level inside the sewage storage unit 3, a capacitive water level sensor 13 is provided. The water level sensor 13 is attached to the outer wall surface of the sewage storage unit 3 and is configured such that the water level is possible without contacting the sewage in the sewage storage unit 3.

  Furthermore, in this embodiment, a pulsator 41 (also serving as a stirring means and a pressure feeding means) is provided inside the sewage reservoir 3. The pulsator 41 has a function of pulverizing the sewage in the sewage W stored in the sewage storage unit 3 while stirring the sewage W, and pumping the sewage W containing the smashed sewage to the drain pipe 42. The pulsator 41 is not particularly limited as long as it has at least an agitation function among the agitation, pulverization, and pressure feeding functions, for example, a driving means such as a motor and a rotary shaft rotatably connected thereto, and Examples include a crushing means such as a bottom plate joined to the driving means, and a pressure feeding means such as an impeller (blade) (more specifically, for example, in Japanese Patent Application No. 2011-054595 by the present applicant). The described pulverized pressure-feeding part 20 can be used suitably, since it was unpublished at the time of filing this application, and the application number was indicated.

  The drain pipe 42 is formed by connecting a straight pipe 42b such as a vinyl chloride pipe to a flexible pipe 42a having flexibility connected to the sewage storage unit 3 with an appropriate joint structure. Through, the sewage W containing the above-mentioned crushed filth is transferred. Thus, the sewage discharge part 4 is comprised from the pulsator 41 and the drain pipe 42. FIG.

  On the other hand, a hand-washing unit 100 as an existing facility having a basin 110 is installed on a wall Rw that is an architectural frame of the living room space R in which the toilet body 1 described above is installed. In the present embodiment, a drain trap 121 is provided in the drain passage 120 of the hand washing unit 100. And the end part 42t of the straight pipe 42b of the drain pipe 42 mentioned above is connected to the downstream of the drain trap 121 in the drain flow path 120 of the hand-washing part 100. FIG. A check valve 43 is provided near the end 42t (downstream end) of the straight pipe 42b of the drain pipe 42.

  In addition, the mobile toilet apparatus 10 of the present embodiment includes a remote controller C. The remote control C is shown in FIG. The remote controller C has a power button 71, a cleaning button 72, and a drainage amount setting button 73. The power button 71 has an input notation 81 “Power”. The washing button 72 has an input notation 82 “flow”. The drainage amount setting button 73 is formed with an input notation 83 “Drainage channel diameter”. Next to the drainage amount setting button 73, input notations 84 “15A”, “30A”, and “45A” are formed. (The drainage amount setting button 73 is not limited to “15A”, “30A”, and “45A”. For example, “10A” and “10A”, which are lower than “40A” of the pipe diameter of the drainage channel that is normally used. 20A "may be selected.) Accordingly, the power button 71, the washing button 72, and the drainage amount setting button 73 form an input operation unit. The input notation 81, the input notation 82, the input notation 83, and the input notation 84 form an input notation part.

  The operation of the mobile toilet apparatus 10 configured as described above will be described below with reference to the configuration of the control system including the control unit 50 (drainage amount setting means) installed in the toilet main body 1 shown in FIG. explain. The mobile toilet device 10 can be operated by the remote control device C, and in addition to the components described above, foreign matter (for example, diapers, water-insoluble tissue, clothes, gums) Etc.), an abnormal sensor 14 for detecting and monitoring whether or not a sufficient amount is accumulated, a motor rotational speed detection sensor 15 for detecting the rotational speed of the motor driving the pulsator 41, a user, etc. Are provided with a display means 61 for visually informing the abnormality and the inspection time, and a voice means 62 for audibly informing the matter (content) equivalent to that notified by the display means 61. .

  First, as shown in FIG. 3, the mobile toilet device 10 has a drainage channel 12 sealed with water, and odor from the downstream side of the drainage channel 12 is caused by the bowl portion 11 of the toilet body 1. It is prevented from leaking to the side. That is, the toilet body 1 has a sealing function. The filth once received in the bowl part 11 is mixed with the water in the sealed part (remaining washing water supplied last time).

  In this state, when the user operates the remote controller C to send a cleaning command for the toilet body 1, the control unit 50 opens, for example, an electromagnetic valve of the water supply unit 2 based on the transmission signal. Is supplied to the bowl portion 11 of the toilet body 1. At the same time, the control unit 50 opens the frappe valve provided at the end of the drainage path 120 inserted into the sewage storage unit 3, so that the sewage W passes through the drainage path 12 and the sewage storage unit 3. It is discharged and transported in, and temporarily stored there.

  Regardless of the presence or absence of the remote control operation C, a signal that detects the water level of the water supply unit 2 is constantly sent to the control unit 50, and a sufficient amount of water for flowing the cleaning water is not stored in the water supply unit 2. In that case, based on the control command of the control unit 50, a warning message for prompting water supply is displayed on the display unit 61 and uttered by the voice unit 62. In addition, a detection signal of foreign matter (for example, a diaper, a water-insoluble tissue, clothes, gum, etc.) accumulated inside the sewage storage unit 3 is constantly sent from the abnormality sensor 14 to the control unit 50. When foreign substances exceeding the allowable amount are accumulated in the sewage storage unit 3, a warning message informing the abnormality is displayed on the display unit 61 and is uttered by the voice unit 62.

  Furthermore, when the wash water is supplied from the water supply unit 2 to the toilet body 1, the vent valve 31 is also opened for a moment, and air is taken into the internal space of the sewage storage unit 3 and the space in the drainage path communicating therewith. The inside of the space is not decompressed, and the sewage W is smoothly transferred. Moreover, since the opened vent valve 31 is closed immediately thereafter, the odor of the sewage W is prevented from leaking out from the sewage reservoir 3.

  When the sewage W is thus transferred from the toilet body 1 to the sewage storage unit 3, the pulsator 41 of the sewage discharge unit 4 is driven based on the control command signal from the control unit 50. Thereby, the sewage W in the sewage storage unit 3 is stirred, and the sewage in the sewage W is further mixed with the washing water while being pulverized, and the mixture is further stirred, so that the fluidity of the sewage W is further improved. . Further, due to the rotation of the pulsator 41, a pumping means such as an impeller provided on the pulsator 41 pushes the sewage W to the flexible pipe 42a of the drain pipe 42, whereby the sewage W in the sewage storage section 3 is converted into the flexible pipe 42a and the straight pipe 42b. It is sent to the downstream side through.

  The amount of drainage to which sewage is pumped by the rotation of the pulsator 41 can be set by operating the drainage amount setting button 73 of the remote controller C. This amount of drainage can be set corresponding to the pipe diameter of the drainage flow path 120 of the hand-washing unit 100, and in the case of this embodiment, the pipe diameter can be set corresponding to 15A, 30A, 45A.

  In the present embodiment, the drainage amount setting button 73 is provided on the remote controller C, but a dedicated button such as the drainage amount setting button 73 is not provided, and other buttons, for example, the washing button 72 may be set. Absent. For example, if the cleaning button 72 is pressed within 1 second, the cleaning operation described in the cleaning button 72 is performed, and if the cleaning button 72 is pressed and held for about 4 seconds, the drainage amount is set as a reverse operation instruction different from the description. It can be configured to do so. In this case, the setting result may be displayed in a lighted manner on the input notation 84, or may be notified by voice in the voice means 62. In this way, by performing the back operation instruction that is not described in the input notation unit, the control unit 50 that is the drainage amount setting means sets the drainage amount of sewage to the drainage amount corresponding to the pipe diameter of the drainage channel 120. The operator performs the operation for separately confirming the back operation instruction, and the possibility of performing the operation by mistake becomes low.

  In the present embodiment, the remote controller C is provided separately from the toilet body 1 as an operation unit including the input operation unit and the input notation unit. However, it is preferable that the function performed by the remote controller C is provided in the toilet body 1.

  In this embodiment, although the amount of waste water to which sewage is pumped by the rotation of the pulsator 41 is set based on the user's setting, it is also preferable to set it automatically regardless of the user's setting. For example, it is also a preferable aspect that the output of the motor that drives the pulsator 41 that is the output of the pressure feeding means, that is, the rotational speed of the motor is detected by the motor rotational speed detection sensor 15 and the amount of drainage is set according to the rotational speed. . This is because the rotational speed of the motor that drives the pulsator 41 is proportional to the pipe diameter of the drainage flow 120 of the hand-washing unit 100.

  Further, for example, the water level sensor 13 detects the water level of the sewage in the sewage storage unit 3, and the time from when the sewage becomes lower than a predetermined water level to the time when the rotational speed of the motor driving the pulsator 41 suddenly increases. It is also a preferable aspect to set the amount of drainage based on time. This is because the time from the time when the sewage becomes lower than the predetermined water level to the time when the rotational speed of the motor driving the pulsator 41 rapidly increases is proportional to the pipe diameter of the drainage flow 120 of the hand-washing unit 100.

  As described above, the check valve 43 provided at the downstream end of the straight pipe 42b has a valve body 43a that is closed when the sewage W is not drained and prevents the sewage W and its odor from flowing backward. However, since the valve body 43a is opened when the sewage W is drained, the sewage W pressure-fed through the flexible pipe 42a and the straight pipe 42b passes through the check valve 43 to the drainage flow path 120 of the hand washing unit 100. Sent to the sewer system. At this time, as described above, the drain trap 121 is provided on the upstream side of the drainage channel 120 of the hand-washing unit 100 (on the basin 110 side with respect to the connection portion between the straight pipe 42b and the drainage channel 120). The amount of drainage flowing into the channel 120 is set to a drainage amount so that sewage does not flow backward to the drain trap 121 side. Therefore, for example, the sewage W can enter the drainage channel 120 without providing a special odor prevention means having an odor prevention function including a valve body that is closed except when draining the used water used in the hand washing unit 100. When flowing in, the sewage W and its odor do not leak to the basin 110 side.

  According to the mobile toilet device 10 configured as described above, the sewage W sent from the toilet main body 1 is converted into the existing sewage W using the hand-washing unit 100 which is an existing facility attached to the wall Rw of the building frame. Since it can flow to a drainage (sewage) system, construction of a new drainage system which has been conventionally required when installing a mobile toilet device becomes unnecessary. Therefore, it solves the problem that occurs due to the time required for the construction or the time required for the construction, that is, the user cannot use the mobile toilet device for a long time or the construction cost increases. can do. That is, by using the mobile toilet device of the present invention and the drainage system therefor, the construction method can be greatly simplified as compared with the conventional one, and as a result, the construction time and construction cost can be greatly reduced. This can greatly contribute to the convenience of the user.

  Moreover, even if the existing equipment is used in this way, the control unit 50 that functions as a drainage amount setting unit that sets the drainage amount of the sewage drained into the drainage pipe to the drainage amount corresponding to the pipe diameter of the drainage channel 120 of the hand washing unit 100 is provided. By providing, the transition to the hand-washing part 100 of an odor is prevented. Since the drain trap is to prevent the odor from moving to the hand-washing part side by forming sealed water, if the sewage flowing from the drain pipe connected to the downstream side of the drain trap 121 flows backward, There is a possibility that the sealed water is replaced by the sewage and the sewage odor moves to the hand-washing unit 100 side. Therefore, in this embodiment, paying attention to the fact that the pipe diameter of the drainage channel 120 of the hand washing unit 100 is actually different, the drainage amount of sewage drained into the drainage pipe is set to the pipe diameter of the drainage channel 120 of the handwashing unit 100. The amount of wastewater corresponding to Thus, by setting the amount of sewage drainage corresponding to the pipe diameter of the drainage channel 120 of the hand washing unit 100, it is possible to suppress the sewage flow exceeding the drainage capacity of the drainage channel 120 of the hand washing unit 100, Backflow to the drain trap 121 side can be suppressed. Therefore, hygiene management of the living room space R in which the mobile toilet apparatus 10 is installed can be suitably performed.

  Moreover, in this embodiment, the control part 50 (drainage amount setting means) changes the output which the pulsator 41 which is a pumping means pumps sewage, and makes wastewater quantity corresponding to the pipe diameter of the drainage flow path 120 by changing the output. Yes.

  Thus, since the amount of drainage of sewage is adjusted by changing the output for pumping sewage, it is possible to reliably and quickly adjust the amount of drainage corresponding to the pipe diameter of the drainage flow path 120 of the hand washing unit 100. Moreover, since the sealing water of the drain trap 121 can be ensured in a clean state, the installation of a check valve for draining can be omitted.

  Moreover, in this embodiment, the remote control C which is an operation part which receives the operation instruction with respect to at least one of the toilet bowl main body 1 and the sewage discharge part 4 is provided, and the control part 50 which is a drainage amount setting means is input into the remote control C which is an operation part. Based on the operation instructions, the amount of wastewater discharged is set to the amount of water discharged corresponding to the pipe diameter of the drainage channel 120.

  As described above, the amount of drainage is adjusted based on the operation instruction input to the remote controller C as the operation unit. Therefore, when the user installs, the operation is performed after confirming the pipe diameter of the connection destination. The amount of drainage adapted to the pipe diameter of 100 drainage channels 120 can be reliably adjusted.

  Moreover, what the person skilled in the art added the design change to the specific examples described above as appropriate is also included in the scope of the present invention as long as the features of the present invention are provided. For example, the elements included in each of the specific examples described above and their arrangement, materials, conditions, shapes, sizes, and the like are not limited to those illustrated, and can be changed as appropriate. Furthermore, the elements included in each of the embodiments described above can be combined as much as technically possible, and combinations thereof are also included in the scope of the present invention as long as they include the features of the present invention.
