Definitions

  • This invention relates to a portable toilet device and it particularly relates to a portable toilet device that is available indoors. It, more particularly, relates to such that can certainly treat any excrement and the like with preventing the excrement from being spilt by providing within a body of the toilet device means for performing breaking-processing (stirring-processing) on the excrement and sending the broken excrement by compression, and a lid for open and closure, which prevents the excrement from being spilt and sending the excrement by compression efficiently.
  • breaking-processing breaking-processing
  • a portable toilet device for an aged person who is necessary for any care or a handicapped person who has any difficulty of going to an existing toilet in his or her house has been developed (see, for example, Japanese Patent Application Publication No.2004-308404 ).
  • This portable toilet device is designed to become a chair-type one in order to be able to be installed indoors so that bowel movement can be done with sitting on the chair.
  • the portable toilet device is provided with a water-supplying hose that flushes rinse water into the toilet device, a drain hose for drain, which drains the excrement, and means for sending the excrement by compression.
  • this invention has solved such the conventional problem and provides a portable toilet device that is available indoors, which can certainly treat any excrement and the like with preventing the excrement from being spilt by particularly providing a lid for open and closure, which prevents the excrement from being spilt, with performing breaking-processing on the excrement, and by performing drain-processing on the broken excrement with sending it by compression.
  • a portable toilet device which is claimed in claim 1
  • the device comprises a body of the device containing a water-supplying nozzle that flushes rinse water near an opening, and a drain opening that is communicated with a stagnant portion provided at a bottom thereof, means for breaking the excrement, which is installed at the stagnant portion of the body of the device, means for sending the broken excrement by compression, which is provided on an upside of the stagnant portion, and a lid for open and closure that closes the stagnant portion tightly, which is provided on an upside of the means for sending the broken excrement by compression.
  • the stagnant portion of the body of the device is provided with the means for breaking the excrement.
  • the means for breaking the excrement includes breaking/stirring type one and the other type one (such as breaking the excrement into fragments by a jet stream). Whatever happen, this means forces the excrement to be broken.
  • the lid for open and closure is provided on an upside of the stagnant portion. It is conceivable that the lid for open and closure includes slidable type one and open/close type one. In course of the breaking process, the upside of the stagnant portion is closed by the lid for open and closure. Therefore, this prevents the excrement that is being broken into fragments from being spilt toward an opening side of the body of the toilet device.
  • the means for sending the broken excrement by compression is driven before or after the breaking process has been completed so that internal pressure in a closed space formed by the stagnant portion and the lid for open and closure can be increased.
  • an electromagnetic valve is opened at a side of the drain opening. This enables the broken excrement to be sent toward a side of an existing toilet device, thereby preventing the excrement from being remained in a drain pipe connected to the existing toilet device.
  • the broken excrement and the like can be certainly drained with preventing the excrement from being spilt.
  • the portable toilet device according to the invention is particularly suitable for a portable toilet equipped with a so-called shower toilet having any buttock-washing function. Any description on the shower toilet equipment will be omitted in the following description.
  • the portable toilet device is applied to a toilet of western type.
  • FIG. 11 relates to an application example of this invention.
  • a toilet facility 3 is set facing a corridor 2 in a house 1.
  • a toilet device 4 and a water-supply tank 5 are installed in the toilet facility 3.
  • a room 6 is positioned as a bedroom in which, for example, a bed 7 is set.

  • a connection portion 26 is formed on a rear surface portion 20b of the body 20 of the toilet device and an electromagnetic valve 24 acting as on-off valve is mounted near the connection portion 26 inside the body 20 of the toilet device.
  • a configuration of the drain portion 22 communicated with the stagnant portion 18 includes configurations of P type, U type, bowl type and the like in addition to the shown configuration. All of these configurations cause similar effects.
  • the electromagnetic valve 24 is controlled so that it opens only when the trap water including the excrement in the stagnant portion 18 is drained out of the toilet device and it closes when the toilet device is not used. This is because the water is prevented from leaking. Simultaneously, this is also because the excrement can be efficiently drained based on a pressure by an air compressor 200, which will be described later.
  • a water-supplying nozzle 28 for rinse water is provided on a wall surface 18a, on a side of the drain portion, of the body 20 of the toilet device near an upper portion thereof.
  • a connecting pipe 30 is arranged between a connection portion 34, which is provided on the rear surface portion 20b of the body, and the water-supplying nozzle 28 and an electromagnetic valve 32 is arranged near the connection portion 34. This is because this electromagnetic valve 32 may control any water supply from a water-supplying hose 12 connected to the connection portion 34.
  • a leak-proof rubber tube 29 is inserted between the water-supplying nozzle 28 and the wall surface 18a, so that water is prevented from leaking to a side of a back-side space 20a of the body 20 of the toilet device.
  • Means 40 for breaking the excrement is installed at a bottom of the stagnant portion 18.

  • connection portions 62A, 62B each of which has a check valve.
  • the end 14a is an end that is connected to a side of the portable toilet device 10
  • the other end 14b is an end that is connected to a side of the drain pipe or the like.
  • a vinyl hose having a small diameter or the like may be used. Since the drain hose 14 enables any liquid mixture (fragments) formed by breaking the excrement and the like to be flown therein, a vinyl hose or the like having a larger diameter than that of the water-supplying hose 12 may be used. This is because liquid mixture with the rinse water, not solidified excrement, is treated.
  • FIG. 3 shows a case where the vinyl hose 14 having a larger diameter than that of the water-supplying hose 12 is used.
  • any marked names such as "Water-supplying Hose” and "Drain Hose” are stamped on a surface of each of the hoses, so that any accidental connection may be certainly prevented.
  • Anti-standardization for shapes or forms of metal connection fittings in the connection portions enables any accidental connection to be prevented.
  • the water-supplying hose and the drain hose are colored with different colors so that such the different colors enable any accidental connection to be also prevented.
  • connection portions 60 (62), each of which has a check valve form a hollow valve operation room 64 with a rectangular profile inside a body 63, as shown in FIG. 4, and a ball member 65 acting as valve action and a push spring 66 urging against it are provided in the room, thereby enabling the valve to be opened by an action of water pressure in a direction of an arrow "a". This prevents backflows from both of the sides of portable toilet device and the water supply pipe.
  • connection portions 60B (62B) of the connection portions 60 (62) are connected to a side of the portable toilet device and a side of drain pipe of the existing toilet device, for example, their internal valves are opened to become any communicate condition in a case where the connection portions 60 (62) are connected if projection members, not shown, each retreating the ball member 65 of the check valve against the push spring 66, are respectively provided in the side of portable toilet device and the side of the drain pipe, or when they are not connected, their internal valves are closed to prevent liquid in each of the hoses from leaking to outside.
  • connection portion 60A is detached while the connection portion 60A of the water-supplying hose 12 is connected to the water supply pipe and the connection portion 60B thereof is connected to the side of the body 20 of the toilet device, any liquid in the hose is not leaked; and even if the other connection portion 60B is detached, any liquid in the hose is not leaked. Similarly, even if the used drain hose 14 is detached, any waste liquid in the hose is not leaked to outside.
  • FIG. 5 shows an outline of an existing toilet facility 3.
  • FIG. 5 illustrates an existing toilet device 4 that is equipped with a shower toilet 80.
  • a diverging pipe 84 is connected to a water pipe (water supply pipe) 82 and a first diverging port 86 is provided to the diverging pipe 84 at a side of the water pipe 82, and is connected with a hose 87 for the shower toilet.
  • a second diverging port 88 is provided thereto nearer the end thereof than the first diverging port, and is connected with a hose 89 for the rinse water.
  • the diverging pipe 84 having such the diverging configuration is used.
  • a check valve 90 is arranged between the first and second diverging ports 86, 88 and a connection portion 92 for connecting the water-supplying hose 12 is provided at a tail end of the diverging pipe 84.
  • the connection portion 60A provided at a tip end of the water-supplying hose 12 is connected to this connection portion 92.
  • arranging the new diverging pipe 84 and attaching the water-supplying hose 12 thereto enables the rinse water to be supplied to the portable toilet device 10. It is because if an error such that water from the hose 89 and the water-supplying hose 12 flows backward should happen, the water to be supplied to a side of the shower toilet is prevented from being mixed with the water flown backward, to arrange the check valve 90 between the first and second diverging ports 86, 88.
  • a tank 96 filled with a sterilizing solution is further able to be inserted to a connection portion for the sterilizing solution at the tail end portion of the diverging pipe 84.
