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, and sewage containing filth and urine (manure) is collected. 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.

  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.

  In order to solve the above-mentioned problems, a mobile toilet apparatus according to the present invention has a bowl portion that receives waste, and a toilet having a drainage channel that discharges wash water supplied to the bowl portion together with waste as waste water from the bowl portion. A main body, a water supply section for supplying cleaning water to the bowl section, a sewage storage section for storing sewage discharged from the drainage flow path of the toilet body, and a drain pipe for discharging sewage from the sewage storage section from the sewage storage section A sewage discharge unit. And in this invention, the edge part of the drain pipe of a sewage discharge part is the hand-washing part (that is, the existing hand-washing attached to the building frame, such as a wall) provided in the building frame of the place where a mobile toilet apparatus is installed. Part) is connected to the downstream side of the odor prevention means formed or provided in the drainage flow path.

  In the mobile toilet apparatus configured as described above, the washing water supplied from the water supply unit to the bowl portion of the toilet body is mixed with filth (preferably agitated) to improve fluidity and become sewage. This sewage is discharged from the bowl through the drainage channel of the toilet body and is stored in the sewage reservoir. Then, the sewage in the sewage storage part is conveyed and discharged to the outside through the drain pipe by the sewage discharge part. 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. Further, the drainage flow path of the hand washing part is formed or provided with odor prevention means, and the end of the drain pipe is connected to the downstream side of the odor prevention means. Migration and leakage from there are prevented.

  More specifically, the odor prevention means has a valve body that opens when draining the used water used in the hand-washing section and closes when the used water is not drained (when the used water is not drained). Is preferred.

  In general, a drainage trap called a P trap is provided in the piping of a drainage channel (drainage system) connected to a hand-washing section because of its shape, for example. This drain trap prevents, for example, sewage odors and odors such as gas from entering the house, and also provides hygiene. HYPERLINK "http://en.wikipedia.org/wiki/%E5%AE%B3%E8%99 % AB "\ o" Pest "It has a structure that prevents pests and rats from entering the room, and functions literally as a trap. Therefore, in many cases, the drain trap is configured to always block the middle of the drain channel with water (usually called sealed water or water seal). By sealing the drainage space with water in this way, the above-described odors and sanitary pests can be prevented from entering the room.

  However, in such drainage and wrap, when the downstream side is relatively negative compared to the upstream side, the sealing water is drawn and flows downstream, and as a result, the sealing effect cannot be obtained. There is a fear. Further, in the drainage trap, the sewage downstream from the sealed water flows backward and the sealed water becomes cloudy, which may cause an unfavorable situation in terms of hygiene management. Further, in the drain trap, when the pipe is clogged downstream of the water seal, the seal water may flow back to the hand-washing section side with the sewage and overflow. Furthermore, when the drain trap pipe is a metal pipe, it may be corroded by sealing water.

  On the other hand, as in one aspect of the present invention, when odor prevention means having a valve body that opens when draining the used water used in the hand-washing section and closes when the used water is not drained, sealing water is unnecessary in the first place. Therefore, there is no fear of losing the sealing effect, there is no concern that the sealing water will become cloudy, there will be no problem of pipe corrosion, and the backflow of sewage to the hand-washing part side due to the valve closing function Is also suppressed. That is, in this aspect, there is no possibility that the odor of sewage leaks out to the hand washing part side through the drainage flow path of the hand washing part.

  Furthermore, as another aspect, the sewage discharge part may have a stirring means for stirring the sewage in the sewage storage part, or instead of or in addition, the sewage discharge part pumps the sewage in the sewage storage part. Even if it has a means, it is suitable.

  If such a stirring means is provided, mixing of the filth and the washing water is promoted and the fluidity of the sewage is further improved, so that the clogging of the sewage pipe on the downstream side is further suppressed. Further, if the structure is such that the sewage is made to flow and transported downstream by the stirring function of the stirring means, a pumping means for pumping the sewage becomes unnecessary. On the other hand, when the pressure feeding means is provided, the sewage can be forcibly conveyed, and pressure is applied to the sewage to further enhance its fluidity, thereby further suppressing the clogging of the sewage pipe on the downstream side. Is done. On the other hand, if both the stirring means and the pressure feeding means are provided, the clogging of the sewage pipe can be further suppressed. Of course, any one of the stirring means and the pressure feeding means may also serve as the other function.

  Furthermore, as another aspect, it is preferable that the drain pipe has a check valve for preventing a backflow from the downstream side to the upstream side of the sewage. The type of the check valve is not particularly limited, and examples thereof include those having a valve body similar to the odor preventing means described above.

  In this way, even if the downstream side of the check valve has a negative pressure relative to the upstream side (toilet body side), the air in the drainage flow path of the toilet body is drawn to the downstream side. It is possible to prevent the occurrence of inconvenience such as running out of sealed water (a pool of washing water) in the drainage flow path of the toilet body.

  The construction method of the mobile toilet device according to the present invention is a system or method for effectively configuring and installing the mobile toilet device of the present invention, and is supplied to the bowl portion for receiving filth and the bowl portion. A toilet body having a drainage channel that discharges the washed water together with filth as sewage from the bowl part, a water supply part that supplies the cleaning water to the bowl part, a sewage storage part that stores the sewage discharged from the discharge channel, Preparing a mobile toilet device comprising a sewage discharge unit having a drain pipe for discharging the sewage of the sewage storage unit from the sewage storage unit, and forming odor prevention means in the drainage channel of the hand-washing unit provided in the building frame Alternatively, an end of the drain pipe is connected to the downstream side of the odor prevention means.

  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 installed at 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.

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 a flap valve, for example, 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.

  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, an odor prevention joint 121 (odor prevention means) is provided in the drainage flow path 120 of the hand washing unit 100. And the end part 42t of the straight pipe 42b of the drainage pipe 42 mentioned above is connected to the downstream of the odor prevention joint 121 in the drainage flow path 120 of the hand-washing part 100. A check valve 43 is provided near the end 42t (downstream end) of the straight pipe 42b of the drain pipe 42.

  Here, FIG. 4 is a piping system diagram showing a configuration of a part of the drain pipe 42 and a part of the drain flow path 120 of the hand washing unit 100. As shown in the figure, the odor prevention joint 121 provided in the drainage flow path 120 has a valve body 121a that restricts the flow of fluid, such as a duckbill valve that closes closely when not draining and opens when draining. doing. The valve body 121a opens toward the downstream side (connection portion between the drainage flow path 120 and the straight pipe 42b) when draining the used water used in the hand washing section 100, and closes when the used water is not drained. Is the body. The check valve 43 provided in the straight pipe 42b of the drain pipe 42 also has a valve body 43a that regulates the flow of fluid such as a duckbill valve. The valve body 43a opens toward the downstream side (the connecting portion between the drainage flow path 120 and the straight pipe 42b) when draining the sewage W through the drain pipe 42, and closes when the sewage W is not drained. It is.

  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 installed inside the toilet body 1 shown in FIG. The mobile toilet device 10 can be operated by the remote control device C, and in addition to the components described above, the water level sensor 13 for detecting and monitoring (monitoring) the water level of the water supply unit 2 and the sewage storage unit 3 Abnormality sensor 14 for detecting and monitoring whether or not foreign substances (for example, diapers, water-insoluble tissues, clothes, gums, etc.) have accumulated more than the allowable amount, and abnormalities and inspection timings for users etc. Display means 61 for visually informing, and sound means 62 for audibly informing the matter (contents) equivalent to notifying by the display means 61 are provided.

  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 flap 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.

  In addition, the signal which detected the water level of the water supply part 2 is always sent to the control part 50 from the water level sensor 13 irrespective of the presence or absence of remote control operation C, and water supply sufficient for flowing washing water is water supply part If not stored in 2, a warning message for prompting water supply is displayed on the display means 61 based on the control command of the control unit 50, and is uttered by the voice means 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.

  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. 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 and is sent to the drainage flow path 120 of the hand washing unit 100. And finally drained into the sewage system. At this time, as described above, the odor prevention joint 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). Since the provided valve body 121a is closed except when the used water used in the hand washing unit 100 is drained, when the sewage W flows into the drainage flow path 120, the sewage W and its odor to the basin 110 side. There is no leakage.

  According to the mobile toilet device 10 configured as described above and the construction method thereof, the sewage W sent from the toilet body 1 using the hand-washing unit 100 that is an existing facility attached to the wall Rw of the building frame. Can be discharged to an existing drainage (sewage) system, so that it is not necessary to construct a new drainage system, which was conventionally necessary when installing a mobile toilet device. 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.

  Even if the existing equipment is used in such a manner, as described above, the odor on the upstream side of the drainage channel 120 of the hand-washing unit 100 (the basin 110 side relative to the connection portion between the straight pipe 42b and the drainage channel 120). The prevention joint 121 is provided, and thereby, when the sewage W flows into the drainage flow path 120, it is possible to prevent the sewage W and its odor from leaking out to the basin 110 side. Therefore, hygiene management of the living room space R in which the mobile toilet apparatus 10 is installed can be suitably performed.

  Furthermore, by using the odor prevention joint 121, conventional sealing water (water sealing structure) becomes unnecessary in the first place. Therefore, the loss of the sealing effect itself due to the loss of the sealing water does not occur, there is no concern that the sealing water becomes cloudy, and the problem of corrosion of the piping due to the sealing water does not occur.

  Furthermore, the odor prevention joint 121 is closed except when draining the used water used in the hand-washing unit 100, and has a valve body 121a that is opened only when the used water flows from the basin 110, It can prevent more reliably that the sewage W and its odor leak to the washbasin 110 side. Thereby, the hygiene management of the living room space R where the mobile toilet apparatus 10 is installed can be implemented more thoroughly.

  Furthermore, a check valve 43 provided on the straight pipe 42b in the drain pipe 42 of the sewage W is closed when the sewage W is not drained, and a valve body 43a that is opened only when the sewage W is flowed is provided. Therefore, even if the downstream side of the check valve 43 has a negative pressure relative to the upstream side (toilet body 1 side), the air in the drainage flow path 12 of the toilet body 1 is drawn to the downstream side. This can be prevented. As a result, it is possible to suppress the occurrence of inconvenience such as running out of the sealed water (reservoir pool) in the drainage flow path 12 of the toilet body 1, and as a result, the sewage W and its odor leak to the toilet body 1 side. It is possible to surely prevent the occurrence of this. Therefore, it becomes possible to carry out the sanitary management of the living room space R where the mobile toilet device 10 is installed more thoroughly.

  Furthermore, the sewage discharge unit 4 has a pulsator 41 as a stirring means, whereby the filth in the sewage W once stored in the sewage storage unit 3 is crushed, and the sewage W has more fluidity. Since it is sent to the drain pipe 42 in an elevated state, the clogging of the sewage W on the downstream side of the sewage reservoir 3 can be effectively suppressed. In addition, since filth can be crushed and clogging of the pipe can be prevented in this way, for example, sewage W can be added to an existing pipe having a small nominal diameter (for example, a pipe of about 20A to 30A corresponding to a flow rate of about 20 L / min). Can flow. Furthermore, as a result, the supply amount of washing water for flowing filth and the like can be reduced (that is, a large flow of washing water is not required), so that the water saving effect is enhanced and the washing water is supplied to the water supply unit 2. It is possible to shorten the storage time or the supply time of cleaning water, and the convenience can be further improved.

  In addition, the pulsator 41 is provided with an impeller or the like although the sewage W is not necessarily required to have a pumping function because the sewage W has a structure in which the fluidity of the sewage W is increased and transferred to the downstream side by the stirring function of the pulsator 41. Therefore, the fluidity is further enhanced by applying pressure to the sewage W containing crushed filth. As a result, the pipe clogging of the sewage W on the downstream side of the sewage reservoir 3 can be further suppressed. Thereby, it can be made to correspond to a thinner pipe diameter, and can contribute to further improvement of water saving and convenience.

  In addition, as above-mentioned, this invention is not limited to said embodiment, A various deformation | transformation is possible in the limit which does not change the summary. For example, the type of the toilet body 1 is not particularly limited, and for example, a siphon type or siphon jet type toilet can be adopted. Moreover, the connection method of the drain pipe 42 of the sewage W and the drain flow path 120 of the hand-washing part 100 can be performed using a various coupling.

  Here, FIG. 6 is a piping system diagram showing another aspect of the configuration of a part of the drain pipe 42 and a part of the drain flow path 120 of the hand washing unit 100. This piping structure is configured in the same manner as the piping structure shown in FIG. 4 except that a Y joint 122 is provided at the connection between the drainage flow channel 120 and the straight pipe 42b. In this embodiment, the straight pipe portion of the Y joint 122 constitutes a part of the drainage flow path 120, and the branch pipe end of the drainage flow path 120 is connected to the Y-shaped end 122a. The end 42t of the straight pipe 42b of the drain pipe 42 is connected to the Y-shaped end 122b (branch pipe portion) of 122. In this way, the sewage W sent through the drain pipe 42 can be more smoothly sent to the downstream side of the drain channel 120.

  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.
