Description

[Technical Field]

[0001] The present invention relates to a toilet device that can be used as a temporary toilet at a construction site, a disaster evacuation shelter, etc., and also as an on-board toilet in a train, an express bus, a camper van, etc. [Background technology]

[0002] In this type of toilet device, if the excrement is stored directly in a tank, problems such as odor leakage and the time and effort required to collect the excrement from the tank have arisen. For this reason, various toilet devices have been proposed that store the excrement in a synthetic resin bag after each use, seal it, and collect it in a tank, from which the sealed bag is then collected.

[0003] A toilet device of this type may include, for example, a cylindrical or rectangular tubular toilet bowl, a toilet seat attached to the upper opening of the toilet bowl, a film storage section located in the upper part of the interior space of the toilet bowl and storing a tubular film in a folded state, a film feeding mechanism located in the interior space of the toilet bowl and feeding the tubular film from the film storage section to a predetermined position directly below the opening of the toilet seat each time the toilet is used, a welding and welding mechanism located below the film feeding mechanism in the interior space of the toilet bowl and welding and welding the film fed by the film feeding mechanism, and a tank connected to the lower opening of the toilet bowl and formed by the welding and welding mechanism to collect the sealed bag containing excrement (see, for example, Patent Documents 1 to 3).

[0004] However, with this conventional toilet device, the film cannot be fed out smoothly, which can cause the film supply to stop. Also, since the film has a relatively large opening diameter and is sandwiched between the pressure-bonding member and the heater for welding and cutting, problems can occur with the film welding, which can result in insufficient sealing of the bag.

[0005] Furthermore, since the device configuration is large and complicated, it is not easy to make the toilet device compact. [Prior art documents] [Patent documents]

[0007] Therefore, an object of the present invention is to provide a compact toilet device that can reliably seal the bag that collects excrement, is easy to maintain, and is easy to use. [Means for solving the problem]

[0008] In order to solve the above problems, according to the present invention, there is provided a toilet device comprising a toilet bowl that is substantially cylindrical or rectangular, and a toilet seat attached to the upper opening of the toilet bowl, wherein each time the toilet is used, a waste collection bag is placed within the toilet bowl and the upper edge of the collection bag is folded back to cover the toilet seat so that the collection bag is attached to the toilet seat, and further comprising: a squeezing mechanism attached between the toilet seat and the toilet bowl that squeezes the upper part of the area in which waste is collected in the collection bag attached to the toilet seat; a heat sealing mechanism attached between the toilet seat and the toilet bowl that welds and seals the area in the collection bag attached to the toilet seat that has been squeezed by the squeezing mechanism; and a tank connected to the lower opening of the toilet bowl that collects the collection bag with the waste sealed inside.

[0009] According to a preferred embodiment of the present invention, the diaphragm mechanism comprises a pair of substrates, each having a circular opening, and a drive plate disposed between the pair of substrates, the drive plate being rotatable about its center with the opening overlapping the openings of the pair of substrates, the drive plate further comprising a plurality of diaphragm plates attached to one surface of the drive plate so as to be rotatable about one end thereof, the one surface of the drive plate being provided with a plurality of guide grooves corresponding to the plurality of diaphragm plates, and the surface of each diaphragm plate facing the drive plate being provided with guide pins which protrude into the corresponding guide grooves, and while the drive plate rotates back and forth within a certain angular range, the diaphragm plates pivot back and forth between an open position where the guide pins abut against one end of the corresponding guide grooves and are retracted outside the openings, and a diaphragm position where the guide pins abut against the other end of the corresponding guide grooves and advance into the openings. [Effects of the Invention]

[0010] According to the present invention, by attaching a collection bag to the toilet device each time it is used, there is no need to store the continuous film in a folded state and provide a structure in the internal space of the toilet bowl for feeding out a fixed length each time it is used, making it possible to make the toilet device extremely simple in structure and easy to maintain.

[0011] Furthermore, a squeezing mechanism is provided to squeeze the opening of the collection bag containing the excrement, and this squeezed area is welded and sealed by a heat sealing mechanism, so the area of ​​the collection bag to be welded is reduced, thereby making it possible to downsize the heater of the heat sealing mechanism and to reliably seal the collection bag containing the excrement. [Brief explanation of the drawings]

[Figure 2] 2 is a plan view showing each component of the throttle mechanism of the toilet apparatus of FIG. 1. FIG. [Figure 3] 3 is a plan view illustrating the interlocking of the drive plate and diaphragm plate of the diaphragm mechanism shown in FIG. 2. FIG. DETAILED DESCRIPTION OF THE INVENTION

[0013] Hereinafter, the configuration of the present invention will be described based on a preferred embodiment with reference to the accompanying drawings. FIG. 1 is a schematic perspective view of a toilet device according to one embodiment of the present invention, in which FIG. 1(A) shows a state in which the throttle mechanism is in an open position and the heat-sealing mechanism is in a standby position, and FIG. 1(B) shows a state in which the throttle mechanism is in a throttle position and the heat-sealing mechanism is in an operating position.

[0014] Referring to FIGS. 1(A) and 1(B), the toilet apparatus of the present invention comprises a toilet bowl 1 having a substantially cylindrical or rectangular cylindrical shape, and a toilet seat 2 attached to the upper opening of the toilet bowl 1.

[0015] In this toilet device, each time the toilet is used, a waste collection bag 3 is placed in the toilet bowl 1, and the upper edge 3a of the collection bag 3 is folded back to cover the toilet seat 2, and the collection bag 3 is attached to the toilet seat 2.

[0016] The toilet apparatus of the present invention further includes a squeezing mechanism 4 that is attached between the toilet seat 2 and the toilet bowl 1 and that squeezes the upper part of the area 3b of the collection bag 3 attached to the toilet seat 2 where excrement is collected.

[0017] 2 is a plan view showing the components of the throttle mechanism of the toilet device of FIG. 1, and FIG. 3 is a plan view illustrating the interlocking of the drive plate and throttle plate of the throttle mechanism shown in FIG.

[0018] 2 and 3, the aperture mechanism 4 has an upper substrate 5 (see FIG. 2(C)) and a lower substrate 6 (see FIG. 2(A)), each having a circular opening, and a drive plate 7 arranged between the upper and lower substrates 5 and 6, which has an annular shape and an opening 7a with the same diameter as the openings in the upper and lower substrates 5 and 6. The drive plate 7 is rotatable around its center with the opening 7a overlapping the openings of the upper and lower substrates 5 and 6.

[0019] The diaphragm mechanism 4 further has a plurality of diaphragm plates 8 (three in this embodiment) attached to one surface (the upper surface in this embodiment) of the drive plate 7 so as to be pivotable around one end 8a. In addition, one surface (top surface) of the drive plate 7 is provided with three guide grooves 7b corresponding to the three aperture plates 8, while the surface of the aperture plate 8 facing the drive plate 7 is provided with guide pins 8b that protrude into the corresponding guide grooves 7b.

[0020] In this way, when the drive plate 7 is rotated and the guide groove 7b moves, the corresponding guide pin 8b of the diaphragm plate 8 moves along the guide groove 7b, thereby causing the diaphragm plate 8 to pivot.

[0021] While the drive plate 7 rotates back and forth within a certain angular range, the aperture plate rotates back and forth between an open position (see Figure 3(A)) in which the guide pin 8b abuts against one end of the corresponding guide groove 7b and retreats to the outside of the opening 7a, and a aperture position (see Figure 3(D)) in which the guide pin 8b abuts against the other end of the corresponding guide groove 7b and advances into the opening 7a.

[0022] The toilet apparatus of the present invention further includes a heat sealing mechanism 9 that is attached between the toilet seat 2 and the toilet bowl 1 and that welds and seals the area of ​​the collection bag 3 that has been squeezed by the squeezing mechanism 4 attached to the toilet seat 2.

[0023] The details of the configuration of the heat sealing mechanism 9 are not shown, but any configuration is acceptable as long as it includes a pair of heaters, a drive unit that supports the pair of heaters and moves them back and forth horizontally between a retracted position where they are spaced apart and positioned outside directly below the toilet seat 2, and an operating position where they press against the opening of the collection bag 3 squeezed by the squeeze mechanism 4 from both sides, a power supply unit, and a control unit that supplies power to each heater from the power supply unit when the pair of heaters are in the operating position but stops the supply of power when the pair of heaters are in the retracted position.

[0024] Furthermore, although not shown, the toilet apparatus of the present invention is equipped with a tank connected to the lower end opening 1a of the toilet bowl 1 for collecting the collection bag 3 containing excrement.

[0025] Thus, when the toilet apparatus of the present invention is used, the squeeze mechanism 4 is in the open position, while the heat-sealing mechanism 9 is in the retracted position and the heater is off. Then, a new excrement collection bag is placed in the toilet bowl 1, and the upper edge 3a of the collection bag 3 is folded back to cover the toilet seat 2, and the collection bag 3 is attached to the toilet seat 2.

[0026] Thereafter, when the user has finished using the toilet, the drive plate 7 of the squeezing mechanism 4 is manually rotated, the squeezing mechanism 4 takes the squeezing position, and then the heat sealing mechanism 9 takes the operating position, and the heater of the heat sealing mechanism 9 is activated, welding and sealing the squeezed portion of the collection bag 3.

[0027] Then, the heat sealing mechanism 9 takes its retracted position and the heater stops, and the operating plate 7 of the throttle mechanism 4 is manually rotated, causing the throttle mechanism 4 to take its open position. This causes the excrement to be collected, and the sealed collection bag 3 is discharged from the lower end opening 1a of the toilet bowl 1 and collected in the tank.

[0028] According to the present invention, by attaching the collection bag 3 to the toilet device each time it is used, there is no need to provide a structure in the internal space of the toilet bowl for storing the continuous film in a folded state and feeding out a fixed length each time it is used, which makes it possible to make the toilet device extremely simple in structure and easy to maintain.

[0029] Furthermore, a constriction mechanism 4 is provided to constrict the opening of the collection bag 3 containing the excrement, and this constricted area is welded and sealed by a heat sealing mechanism 9, so that the area of ​​the collection bag 3 to be welded is reduced, the heater of the heat sealing mechanism 9 can be made smaller, and the collection bag 3 containing the collected excrement can be securely sealed.
