The frame 21 is housed within the lower part 23. The frame portions 21a and 21b are disposed on a pair of left and right wall portions 2301 of the lower part 23. Although Fig. 5 shows a state in which the four legs 7 and the reinforcing plate 16 are attached to the frame 21, the four legs 7 and the reinforcing plate 16 are attached to the frame 21 after it is housed in the lower part 23.

[0047] The first frame portion 21a and the second frame portion 21b have a common structure. A pair of reinforcing plates 16, which are connected in an X-shape in plan view, are connected to the lower end of the first frame portion 21a and the lower end of the second frame portion 21b. Each of the pair of reinforcing plates 16 is a strip-shaped member extending in one direction. The pair of reinforcing plates 16 are connected in an X-shape in plan view by connecting their central portions in the longitudinal direction. Both ends of each of the pair of reinforcing plates 16 in the longitudinal direction are fixed to the lower surfaces of the first frame portion 21a and the second frame portion 21b.

[0048] Each of the first frame portion 21a and the second frame portion 21b has a pair of front and rear leg attachment portions 210 and a connecting wall 211 connecting the pair of front and rear leg attachment portions 210.

[0050] 2-7. Sealed unit 4, the sealing unit 18 is provided with a bag attachment portion 14 and a sealing device 15. The sealing unit 18 is installed between an inner part 24 and an outer part 25.

[0051] The sealing unit 18 has a flat, box-shaped case 180 with an open top. The bag attachment portion 14 and the sealing device 15 are provided in the case 180. An opening 182 that passes through the bottom wall 181 in the vertical direction is provided in a bottom wall 181 of the case 180. Figures 7 and 8 show the sealing unit 18 attached inside the outer part 25 and not covered by the inner part 24.

[0052] 2-8.Bag attachment part As shown in Figure 3, bag attachment part 14 is located below toilet seat 3 and is configured so that mouth 100 of bag 10, which receives the user's excrement, can be attached. Bag 10 is attached to bag attachment part 14 with mouth 100 open. The bottom of bag 10 with mouth 100 attached to bag attachment part 14 is supported by tray 5. Therefore, the downward load acting on bag 10 is mainly supported by tray 5.

[0053] The bag attachment part 14 is configured so that the mouth 100 of the bag 10 comes off when a load (a downward load in this embodiment) of a predetermined magnitude or more is applied to the mouth 100 of the bag 10. The bag attachment part 14 has a first clamping part 140 that elastically clamps and supports the first part 100a of the opposing first and second parts 100b of the mouth 100 of the bag 10, and a second clamping part 141 that elastically clamps and supports the second part 100b. The first clamping part 140 has a stronger clamping force on the mouth 100 of the bag 10 than the second clamping part 141.

[0054] 8, the first clamping portion 140 is disposed in a portion of the bottom wall 181 that is in front of the opening 182. When the inner part 24 is attached to the sealing unit 18, the first clamping portion 140 is located below the front edge of the top opening 2400 of the inner part 24. The first clamping portion 140 is configured to elastically clamp the first portion 100a, which is the front portion of the mouth 100 of the bag 10 in the open state.

[0055] The first clamping unit 140 is composed of two clamping units 140a and 140b spaced apart in the left-right direction. The two clamping units 140a and 140b have a common structure. In this embodiment, each of the two clamping units 140a and 140b includes a first clamping unit 1400, a second clamping unit 1401 positioned behind the first clamping unit 1400 so as to face the first clamping unit 1400, and a spring member 1402 that elastically presses the second clamping unit 1401 against the first clamping unit 1400.

[0056] When the inner part 24 is attached onto the sealing unit 18, the second clamping portion 1401 is located rearward of the front edge of the upper surface opening 2400 of the inner part 24, and is exposed upward through the upper surface opening 2400 in plan view. When the inner part 24 is attached onto the sealing unit 18, the first clamping portion 1400 is located forward of the front edge of the upper surface opening 2400 of the inner part 24, and is not exposed upward through the upper surface opening 2400 in plan view.

[0057] In this embodiment, the second clamping portion 1401 and the spring member 1402 are configured as a spring hinge. A plate on one side of the spring hinge is the second clamping portion 1401, and the spring of the spring hinge is the spring member 1402. The plate on the other side of the spring hinge is sandwiched between the block-shaped first clamping portion 1400 and the bottom wall 181.

[0058] Second clamping portion 1401 is plate-shaped with its thickness in the front-to-rear direction. Second clamping portion 1401 is rotatable around its lower end so that its upper end moves back and forth, and is biased forward (toward first clamping portion 1400) by spring member 1402. As a result, the front portion of the opening of bag 10 (first portion 100a) is elastically clamped between first clamping portion 1400 and second clamping portion 1401.

[0059] In this embodiment, the upper part 1403 of the second clamping part 1401 is inclined so that the upper part is positioned further rearward. The upper part 1404 of the rear surface of the first clamping part 1400 that faces the second clamping part 1401 is inclined so that the upper part is positioned further forward. As a result, the gap between the first clamping part 1400 and the second clamping part 1401 becomes wider in the front-to-rear direction at the upper parts 1403, 1404, making it easier to insert the opening 100 of the bag 10.

[0060] As shown in Figure 7, the second clamping portion 141 has a similar structure to the first clamping portion 140, and differs from the first clamping portion 140 only in that it has a weaker clamping force on the mouth 100 of the bag 10 than the first clamping portion 140.

[0061] Second clamping unit 141 is composed of two clamping units 141a and 141b positioned at a distance in the left-right direction. Two clamping units 141a and 141b have the same structure. Each of two clamping units 141a and 141b has a first clamping unit 1410, a second clamping unit 1411 positioned in front of first clamping unit 1410, and a spring member 1412 that elastically presses second clamping unit 1411 against first clamping unit 1410. Spring member 1412 has a smaller elastic force than spring member 1402. Therefore, second clamping unit 141 releases opening 100 of bag 10 more easily than first clamping unit 140.

[0062] An upper portion 1413 of the second clipping portion 1411 is inclined so that the upper portion is positioned further forward, and an upper portion 1414 of the front surface of the first clipping portion 1410 is inclined so that the upper portion is positioned further rearward.

[0063] The second clamping portion 141 is installed on a movable portion 151 that moves in the front-rear direction by operating an operating portion 150 provided in the sealing device 15. Therefore, the second clamping portion 141 is movable in the front-rear direction.

[0064] When the internal part 24 is attached onto the sealing unit 18 and the movable part 151 and the second clamping part 141 are in their rear end positions, the second clamping part 141 is located forward of the rear edge of the top opening 2400 of the internal part 24 and is exposed upward through the top opening 2400 in plan view. In the same state, the first clamping part 1410 is located rearward of the rear edge of the top opening 2400 of the internal part 24 and is not exposed upward through the top opening 2400 in plan view.

[0065] 2-9. Sealing device 7 and 8 is configured to be able to seal the mouth 100 of the bag 10. The sealing device 15 has an operating part 150 that is operated by a user or a caregiver, a movable part 151 that moves back and forth in response to the operation of the operating part 150, and a connecting part 152 that connects the operating part 150 and the movable part 151. The sealing device 15 further has a thermocompression part 153 that thermocompresses the mouth 100 of the bag 10 in the closed state. The operating part 150, the movable part 151, the connecting part 152, and the thermocompression part 153 are provided below the bottom wall 181 of the case 180.

[0066] The operating part 150 is a rod-shaped member that extends in the left-right direction and has an arc-like shape in a plan view that is convex toward the front, and protrudes forward beyond the front wall 183 of the case 180. The operating part 150 is inserted into the insertion part 254 (see FIG. 4) of the outer part 25, and is exposed at the front side of the toilet body 2.

[0067] Movable part 151 is a block-shaped member extending in the left-right direction. Second clamping part 141 is fixed to the upper surface of movable part 151. A pressing plate 154 for pressing bag 10 from behind is rotatably suspended from the lower surface of movable part 151. The front surface of movable part 151 forms pressing surface 1510 that presses part of mouth 100 of bag 10 against thermocompression part 153.

[0068] The connecting unit 152 has a pair of left and right rod-shaped connecting members 1520. The left connecting member 1520 is connected to the left end of the operating unit 150 and the left end of the movable unit 151, and the right connecting member 1520 is connected to the right end of the operating unit 150 and the right end of the movable unit 151.

[0069] Each of the pair of left and right connecting members 1520 has a front part 1520a connected to the operation unit 150 and a rear part 1520b connected to the movable unit 151. The rear end of the front part 1520a is connected to the front end of the rear part 1520b so as to be rotatable around an axis parallel to the left-right direction.

[0070] 7, the operating unit 150 can be pulled forward to a front end position where the pressing surface 1510 of the movable part 151 abuts the thermocompression bonding unit 153 via the opening 100 of the bag 10. The operating unit 150 can then rotate rearward and upward from the front end position to a thermocompression bonding position where the pressing surface 1510 abuts the thermocompression bonding unit 153. When the operating unit 150 is in the thermocompression bonding position, the thermocompression bonding unit 153 is activated and heats up, heating the opening 100 of the bag 10 to seal it by thermocompression. The operating unit 150 can be moved from the thermocompression bonding position to the front end position and then moved from the front end position to the operating position.

[0071] When the operating part 150 is moved from the storage position to the front end position, a pressure plate 154 rotatably suspended from the movable part 151 presses the part below the mouth 100 on the rear face of the bag 10 to move it forward.

[0072] The sealing device 15 further has a pair of left and right pressing devices 155 that operate when the operating part 150 is moved from the storage position to the front end position to move the left and right portions of the mouth 100 of the bag 10 inward. The pair of left and right pressing devices 155 are arranged on the upper surface of the bottom wall 181 of the case 180, on the left and right portions of the opening 182.

[0073] 2-10. Saucer 3, tray 5 is disposed below bag attachment part 14 in storage space S1. More specifically, tray 5 is disposed in a position where the bottom surface of bag 10 rests when opening 100 is attached to bag attachment part 14. By receiving the bottom surface of bag 10, tray 5 supports the downward load acting on bag 10 from the excrement inside bag 10.

[0074] The tray 5 is supported at its left and right ends and rear end by a tray support part 2305 and a pair of left and right support parts (see FIG. 6) provided on the bottom wall 230 of the lower part 23. As a result, the tray 5 is placed at the lower end of the storage space S1. The tray 5 is provided so as to be able to be taken in and out through a side opening 2311.

[0075] As shown in Figures 9A to 9C, the upper surface 50 of the tray 5 has a bottom surface 500 that forms the lowest part of the upper surface 50, and a plurality of inclined surfaces 501 that are positioned surrounding the bottom surface 500 and slope downward toward the bottom surface 500.

[0076] The tray 5 is rectangular in plan view. The tray 5 has a peripheral wall portion 51 that is shaped like a rectangular frame in plan view and protrudes upward from the outer peripheral edge of the top surface 50. The tray 5 further has a front wall 52 that connects the front end of the top surface 50 to the peripheral wall portion 51 above it. The front wall 52 is a trapezoidal wall when viewed from the front. The rear surface of the front wall 52 is slightly inclined with respect to the vertical plane so that the lower portion is positioned further rearward. The tray 5 also has a locking piece 53 that protrudes downward from the rear end. The locking piece 53 hooks into a locking groove 23050 (see Figure 6) of the tray support portion 2305 of the bottom wall 230.

[0077] The bottom surface 500 is a portion of the top surface 50 that is forward of the center in the left-right and front-rear directions. The bottom surface 500 is flat, and its vertical position is constant throughout. The multiple inclined surfaces 501 include a first inclined surface 501a located in front of the bottom surface 500, a pair of second inclined surfaces 501b located on the left and right of the bottom surface 500, and a third inclined surface 501c located behind the bottom surface 500.

[0078] The first inclined surface 501a, the pair of second inclined surfaces 501b, and the third inclined surface 501c are each a flat surface inclined so that a portion closer to the bottom surface 500 is positioned more downward. In this embodiment, the first inclined surface 501a is triangular in plan view and is inclined so that a portion closer to the rear is positioned more downward. The pair of left and right second inclined surfaces 501b are trapezoidal in plan view and are inclined so that a portion closer to the inside in the left-right direction is positioned more downward. The third inclined surface 501c is triangular in plan view and is inclined so that a portion closer to the front is positioned more downward. The front end of the first inclined surface 501a and the front end of the pair of second inclined surfaces 501b are continuous with the lower end of the rear surface of the front wall 52.

[0079] With the opening 100 attached to the bag attachment portion 14, the bottom surface of the bag 10 rests on the upper surface 50 of the tray 5. As a result, the waste contained in the bag 10 is guided toward the bottom surface 500 by the multiple inclined surfaces 501 of the upper surface 50, and can be concentrated at the front center of the bottom surface of the bag 10. In addition, because a peripheral wall portion 51 is provided on the outer periphery of the upper surface 50 of the tray 5, the waste in the bag 10 can be prevented from climbing over the peripheral wall portion 51 and moving outside the tray 5. Therefore, the toilet 1 of this embodiment can prevent the waste on the bottom surface of the bag 10 from moving outside the tray 5 and applying a large downward load to the opening 100 of the bag 10.

[0080] Furthermore, in the tray 5 of this embodiment, the excrement in the bag 10 is guided to the front, so when the operating part 150 is operated to move the movable part 151 to the front, the pressure plate 154 is less likely to be loaded, and the rear surface of the bag 10 can be easily moved to the front.

[0081] By opening the lid 6 and opening the side opening 2311, the tray 5 is exposed to the side (more specifically, the front) through the side opening 2311. The tray 5 can be taken in and out through the side opening 2311. When the side opening 2311 is closed by the lid 6, the tray 5 is not exposed toward the front of the toilet bowl 1.

[0082] 2-11.Toilet seat 2 is installed on the toilet body 2. One end of the toilet seat 3 (the rear end in the reclined position) is rotatably attached to a toilet seat attachment portion 2420 on the rear wall 242 of the inner part 24.

[0083] The toilet seat 3 is rotatable between a lying position along the bottom wall 240 of the inner part 24 and an upright position (see FIG. 2) in which it stands on the rear wall 242 of the inner part 24. When the toilet seat 3 is in the lying position, it is contained in a space surrounded by the bottom wall 240 of the inner part 24, the pair of first wall portions 2411 of the front wall 241, the rear wall 242, and the pair of left and right side walls 243. When the toilet seat 3 is in the lying position, the central opening 30 of the toilet seat 3 is located above the top opening 2400 of the toilet body 2.

[0084] 2-12. Toilet lid 1 and 2 can cover the toilet seat 3 and the top opening 2400. One end of the toilet lid 4 (the rear end in the lying position) is rotatably attached to the toilet lid attachment portion 2520 of the rear wall 252 of the outer part 25.

[0085] The toilet lid 4 is rotatable between a lying position (see FIG. 1) in which it fits along the toilet seat 3 in the lying position, covering the toilet seat 3 and the upper opening 2400, and an upright position (see FIG. 2) in which it is folded and stands on the rear wall 252 of the outer part 25. When in the lying position, the toilet lid 4 rests on the front wall 251, rear wall 252, and pair of left and right side walls 253 of the outer part 25.

[0086] The upper surface of the toilet cover 4 is provided with a hook 40 that can be used to hook a finger when switching the toilet cover 4 between a lying position and an upright position.

[0087] 3. How to use the toilet An example of how to use the toilet 1 of this embodiment described above will now be described.

[0088] First, the user or caregiver (hereinafter referred to as "user, etc.") opens the toilet lid 4 and toilet seat 3 (that is, stands up) to expose the upper opening 2400 of the toilet body 2 (see FIG. 2).

[0089] Next, the user or the like widens the opening 100 of the bag 10 and inserts the opposing first portion 100a and second portion 100b of the opening 100 of the bag 10 from above into the first clamping portion 140 and second clamping portion 141 of the bag attachment portion 14, respectively, so that the opening 100 is elastically clamped (see FIG. 3). The bottom surface of the bag 10 with the opening 100 attached to the bag attachment portion 14 is received by the receiving tray 5. At this time, it is preferable to insert a hand into the open opening 100 of the bag 10 and spread the bag 10 so that the bottom surface of the bag 10 is aligned with the upper surface of the receiving tray 5.

[0090] Next, the user pours a coagulant into the bag 10 to solidify the liquid, and closes the toilet seat 3 (i.e., places it in a lying position). This puts the toilet 1 into a usable state where the user can sit on the toilet seat 3 and defecate.

[0091] After the user has excreted, the user closes the toilet lid 4. All subsequent tasks can be performed with the toilet lid 4 closed.

[0092] Next, the user or the like grasps the operating part 150 of the sealing device 15 and pulls it from the storage position to the front end position. This causes the movable part 151 connected to the operating part 150 to move forward, and the second part 100b on the rear side of the mouth 100 of the bag 10, which is clamped by the second clamping part 141 on the movable part 151, approaches the first part 100a (the front part) of the mouth 100 of the bag 10. At this time, the part between the first part 100a and the second part 100b of the mouth 100 of the bag 10 is pushed inward in the left-right direction by the pressing device 155 of the sealing device 15, and is clamped between the first part 100a and the second part 100b. At this time, the rear surface of the bag 10 is pushed forward by the pressing plate 154 connected to the movable part 151, and the entire bag 10, not just the mouth 100, moves forward.

[0093] Next, the user or the like grasps operating part 150 of sealing device 15, rotates it from the front end position to the sealing position, and waits at the sealing position for a predetermined time (about several seconds). As a result, the portions slightly below first part 100a and second part 100b of mouth 100 of bag 10 are melted by the heat of thermocompression part 153, which is activated while sandwiched between pressing surface 1510 of movable part 151 and thermocompression part 153, and mouth 100 of bag 10 is sealed.

[0094] Next, the user or the like grasps the operating part 150 of the sealing device 15 and rotates it from the sealing position to the front end position, and then returns it from the front end position to the storage position. This causes the movable part 151 connected to the operating part 150 to move rearward, and the opening 100 of the sealed bag 10, which has been elastically clamped by the second clamping part 141 on the movable part 151, is released. As a result, the opening 100 of the sealed bag 10 is now clamped only by the first clamping part 140.

[0095] Next, the user or the like opens lid 6 to open side opening 2311, inserts a finger into side opening 2311, and pulls sealed bag 10 downward to remove first portion 100a of mouth 100 of bag 10 from first clamping unit 140. At this time, a force that resists the elastic force of first clamping unit 140 is applied to first portion 100a of mouth 100 of bag 10, which is elastically clamped by first clamping unit 140. As a result, first portion 100a is released from first clamping unit 140, and mouth 100 of sealed bag 10 can be removed from bag attachment unit 14.

[0096] Next, the user or the like removes the sealed bag 10 to the outside through the side opening 2311 and discards the sealed bag 10. At this time, if the tray 5 is dirty, the tray 5 can be removed through the side opening 2311 and washed. In this case, the user or the like puts the removed tray 5 back into the side opening 2311 and returns the tray 5 to its original position. Next, the user or the like closes the side opening 2311 with the lid 6.

[0097] Next, the user opens the toilet lid 4 and the toilet seat 3, and attaches the opening 100 of the new bag 10 to the bag attachment portion 14 in the same manner as described above.

[0098] 4. Effects In the toilet 1 of this embodiment described above, after the user's excrement is collected in the bag 10, the toilet lid 4 can be used to cover the top opening 2400 to cover the bag 10 containing the excrement, and the opening 100 of the bag 10 can be sealed and closed with the sealing device 15. Then, in the toilet 1 of this embodiment, with the lid 6 open and the side opening 2311 exposed, the opening 100 of the sealed bag 10 can be removed from the bag attachment part 14 by inserting a finger into the side opening 2311 and pulling strongly on the sealed bag 10. Therefore, in the toilet 1 of this embodiment, the inner side of the opening 100 of the bag 10, which is easily soiled by scattered excrement, is less visible, and there is no need to grab the opening 100 of the bag 10 from above to remove it, which improves the feeling of cleanliness.

[0099] Furthermore, in the toilet 1 of this embodiment, the bottom surface of the bag 10 can be supported by the tray 5 when the mouth 100 of the bag 10 is attached to the bag attachment part 14, so the weight of the excrement contained in the bag 10 is supported by the tray 5, preventing a large load from being applied to the mouth 100 of the bag 10. Therefore, in the toilet 1 of this embodiment, it is possible to prevent the mouth 100 of the bag 10 from coming off the bag attachment part 14 before the mouth 100 of the bag 10 is sealed.

[0100] Furthermore, in the toilet 1 of this embodiment, the mouth 100 of the bag 10 is elastically clamped by each of the pair of clamping parts 140, 141. Therefore, in the toilet 1 of this embodiment, by applying a force that resists the elastic force of the clamping parts 140, 141, the mouth 100 of the bag 10 can be easily removed from the pair of clamping parts 140, 141.

[0101] Furthermore, in the toilet bowl 1 of this embodiment, the upper surface 50 of the tray 5 has a lowermost surface 500 located toward the center of the upper surface 50 and a plurality of inclined surfaces 501 located around the lowermost surface 500, which makes it easier for the excrement excreted in the bag 10 to be concentrated toward the center of the upper surface 50 of the tray 5. As a result, in the toilet bowl 1 of this embodiment, the excrement in the bag 10 spreads outward from the tray 5, increasing the downward load on the mouth 100 of the bag 10 and further preventing the mouth 100 of the bag 10 from coming off the bag attachment part 14.

[0102] Furthermore, in the toilet bowl 1 of this embodiment, the bottom surface 500 is located in front of the upper surface 50 of the tray 5, so excrement tends to collect on the front portion of the bottom surface of the bag 10. Therefore, in the toilet bowl 1 of this embodiment, when the second clamping portion 141 and the pressure plate 154 on the movable portion 151 press the rear portion of the bag 10 forward to move it, the excrement inside the bag 10 is less likely to provide resistance, making it easier to move. Furthermore, during this movement, the second portion 100b of the bag 10 clamped by the second clamping portion 141 is less likely to be loaded, which prevents the second portion 100b from coming off the second clamping portion 141.

[0103] Furthermore, in the toilet 1 of this embodiment, the side opening 2311 is provided on the front side of the toilet body 2 when viewed from the user seated on the toilet seat 3, so the lid 6 can be opened and closed and the sealed bag 10 can be removed in a relatively large space in front of the toilet body 2. Therefore, in the toilet 1 of this embodiment, the various operations associated with removing the sealed bag 10 can be easily performed.

[0104] 5. Variations Next, a description will be given of modified examples of the toilet 1 of the above-described embodiment. The modified examples shown below can be combined as appropriate.

[0105] The toilet 1 does not have to include the tray 5. The toilet 1 may be configured so that the bottom of the bag 10 with the opening 100 attached to the bag attachment part 14 rests on the floor or other member. In this case, the weight of the excrement contained in the bag 10 is supported by the floor or other member, preventing a large load from being applied to the opening 100 of the bag 10.

[0106] Furthermore, bag attachment part 14 does not have to have first clamping part 140 that elastically clamps and supports first portion 100a of mouth 100 of bag 10, and second clamping part 141 that elastically clamps and supports second portion 100b. Bag attachment part 14 may be configured so that mouth 100 of bag 10 comes off when a load greater than a predetermined value is applied to mouth 100 of bag 10 by a method other than elastic clamping and support.

[0107] Furthermore, the first clamping portion 140 does not need to have a stronger clamping force for the mouth 100 of the bag 10 than the second clamping portion 141, and may be configured in other ways so that the mouth 100 of the bag 10 can be more easily removed from the second clamping portion 141 than from the first clamping portion 140.

[0108] Furthermore, the upper surface 50 of the tray 5 does not have to have the lowermost surface 500 and the inclined surface 501, and may be flat.

[0109] Furthermore, the side opening 2311 does not have to be located on the front surface of the toilet body 2 when viewed from a user sitting on the toilet seat 3, but may be located on the left or right surface or rear surface of the toilet body 2.

[0110] In addition, the sealing device 15 may have a remote control instead of the operating unit 150 which is operated manually or mechanically, and may be configured so that the movable unit 151 is automatically moved by operating the remote control, and the mouth 100 of the bag 10 is sealed by the thermo-sealing unit 153.

[0111] Furthermore, sealing device 15 that seals opening 100 of bag 10 is not limited to the above-described structure, and may be a device that seals opening 100 of bag 10 by a method other than thermocompression bonding.

[0112] The toilet body 2 may also be one in which the housing 20 and the frame 21 are integrally formed.

[0113] Furthermore, the upper part 22 is not limited to a combination of the inner part 24 and the outer part 25, but may be formed from a single member.

[0114] (summary) As in the embodiment and its modified example described above, the toilet (1) of the first aspect has the following configuration.

[0115] That is, the toilet bowl (1) of the first embodiment comprises a toilet body (2) having an internal storage space (S1), an upper surface opening (2400) that communicates with the storage space (S1) on its top surface, and a side surface opening (2311) that communicates with the storage space (S1) on its side surface. The toilet bowl (1) further comprises a toilet seat (3) placed on the toilet body (2), and a toilet lid (4) that can cover the toilet seat (3) and the upper surface opening (2400). The toilet bowl (1) further comprises a bag attachment part (14) located below the toilet seat (3) and to which the opening (100) of a bag (10) that receives the user's excrement is detachably attached, and a sealing device (15) that can seal the opening (100) of the bag (10). The toilet bowl (1) further comprises a lid (6) that opens and closes the side surface opening (2311). The bag attachment portion (14) is configured so that the mouth (100) of the bag (10) comes off when a load of a predetermined magnitude or more is applied to the mouth (100) of the bag (10).

[0116] In the toilet bowl (1) of the first aspect having the above-described configuration, after the user's excrement is collected in the bag (10), the toilet lid (4) can be used to cover the top opening (2400) to cover the bag (10) containing the excrement, and the opening (100) of the bag (10) can be sealed and closed with the sealing device (15). Thereafter, in the toilet bowl (1) of the first aspect, with the lid (6) open to expose the side opening (2311), a user can insert a finger into the side opening (2311) and pull the sealed bag (10) hard to remove the opening (100) of the sealed bag (10) from the bag attachment portion (14). Therefore, in the toilet bowl (1) of the first aspect, the inner side of the opening (100) of the bag (10), which is easily soiled by scattered excrement, is less visible, and there is no need to grab the opening (100) of the bag (10) from above to remove it, thereby improving the feeling of cleanliness.

[0117] Furthermore, like the embodiment and its modification described above, the toilet (1) of the second aspect additionally comprises the following features in addition to the features of the first aspect.

[0118] That is, the toilet bowl (1) of the second embodiment further includes a tray (5) that is arranged in the storage space (S1) below the bag attachment portion (14). The tray (5) is arranged in a position where the bottom surface of the bag (10) rests when attached to the bag attachment portion (14).

[0119] In the second embodiment of the toilet (1) having the above configuration, the weight of the excrement in the bag (10) can be received by the tray (5), which prevents the weight of the excrement from being applied to the mouth (100) of the bag (10), and makes it easier to prevent the mouth (100) of the bag (10) from coming off the bag attachment portion (14).

[0120] Furthermore, like the embodiment and its modification described above, the toilet (1) of the third aspect additionally comprises the following features in addition to the features of the first or second aspect.

[0121] That is, in the toilet bowl (1) of the third embodiment, the bag attachment portion (14) has a first clamping portion (140) that elastically clamps and supports the first portion (100a) of the opening (100) of the bag (10) that faces each other, and a second clamping portion (141) that elastically clamps and supports the second portion (100b).

[0122] In the toilet (1) of the third aspect having the above-mentioned configuration, the mouth (100) of the bag (10) can be easily removed.

[0123] Furthermore, like the embodiment and its modification described above, the toilet (1) of the fourth aspect additionally comprises the following features in addition to the features of the third aspect.

[0124] That is, in the toilet bowl (1) of the fourth embodiment, the first clamping portion (140) has a stronger clamping force on the mouth (100) of the bag (10) than the second clamping portion (141).

[0125] In the toilet bowl (1) of the fourth aspect having the above configuration, when a load is applied to the mouth (100) of the bag (10), the first clamping portion (140) can easily maintain support of the first portion (100a), and it is easy to prevent both the first portion (100a) and the second portion (100b) from coming off.

[0126] Furthermore, like the embodiment and its modification described above, the toilet (1) of the fifth aspect additionally comprises the following features in addition to the features of the second aspect.

[0127] That is, in the fifth embodiment of the toilet bowl (1), the upper surface (50) of the tray (5) has a lowest surface (500) that forms the lowest part of the upper surface (50), and a plurality of inclined surfaces (501) that are positioned so as to surround the lowest surface (500) and slope downward toward the lowest surface (500).

[0128] In the toilet bowl (1) of the fifth aspect having the above configuration, the waste received on the bottom surface of the bag (10) can be moved toward the bottom surface (500) by the inclined surface (501) of the upper surface (50) of the tray (5). Therefore, in this toilet bowl (1), it is possible to prevent the waste on the bottom surface of the bag (10) from spreading outward from the tray (5) and increasing the load on the mouth (100) of the bag (10), and it is possible to make it difficult for the mouth (100) of the bag (10) to come off the bag attachment portion (14).

[0129] Furthermore, like the embodiment and its modified example described above, the toilet (1) of the sixth aspect additionally comprises the following features in addition to the features of any one of the first to fifth aspects.
