[Toilet device]
FIG. 1 is a perspective view of a toilet device 10 according to the embodiment. FIG. 2 is a side view of the toilet device 10, and FIG. 3 is an exploded view of the toilet device 10.
The toilet device 10 includes a toilet 12 (see FIG. 3) in which a toilet seat 16 for a user to sit on a toilet and a toilet bowl 20 for receiving filth are integrally formed, and a housing 14 that supports the toilet 12. Is provided. The toilet bowl 20 is formed with a filth input port through which filth discharged by the user is input at the top and a filth discharge hole at the bottom for discharging the filth. The waste discharge hole is configured to be smaller than the waste input port. Inside the housing 14, a cartridge 50 for storing filth is detachably attached to the housing 14. The housing 14 is provided with a handle 15 for carrying the toilet device 10. However, as will be described later, when the filth stored in the cartridge 50 is discarded, only the cartridge 50 can be removed and carried. Therefore, it is not necessary to carry the entire toilet device 10. By adopting such a configuration, even when the toilet device 10 is installed in a bathroom or the like, the cartridge 50 can be protected from moisture, dirt, and the like, and the cartridge is used to discard the stored filth. When carrying 50, it is possible to prevent moisture and dirt from adhering to the user's body and clothes from the surface of the cartridge 50. In addition, while the cartridge 50 is being transported for disposal of filth, the toilet device 10 can be used by mounting another cartridge 50.

  The opening of the toilet bowl 12 or the opening of the cartridge 50 is opened when passing material such as filth and washing water is introduced, and the passing material is allowed to pass through, and closed at other times so that contents and odors are not discharged to the outside. A valve is provided to do this. Therefore, in FIGS. 1 to 3, the lid for closing the opening of the toilet 12 is not provided on the upper part of the toilet 12. However, in another example, a lid may be provided on the opening of the toilet 12. Details of the valve will be described later.

  As shown in FIG. 3, the housing 14 has a truncated cone shape whose bottom surface is a rounded rectangle or an ellipse, and can be divided into a body portion 14 a and a bottom surface portion 14 b. As a result, when the toilet device 10 is transported from the production site to the use site or stored in a warehouse or the like for a disaster, the body portion 14a and the bottom surface portion 14b can be stacked separately. The required space can be reduced. Further, if the housing 14 is divided into the body portion 14a and the bottom surface portion 14b, each can be made independent, so that the body portion 14a and the bottom surface portion b can be stably stacked. In the state where the toilet bowl 12 is placed above the trunk section 14a, the combination thereof may be stacked, or the trunk section 14a and the toilet bowl 12 may be stacked separately. Moreover, the handle 15 may be piled up in the state attached to the housing 14, or the handle 15 may be removed from the housing 14 and stored or transported separately. Since the boundary line between the trunk portion 14a and the bottom surface portion 14b is in an inconspicuous position below the toilet device 10, it is also preferable in terms of aesthetics. In another example, the housing 14 may be divisible into more parts. Since a valve is provided at the opening of the toilet 12 or the opening of the cartridge 50 to prevent leakage of filth and odor stored in the cartridge 50, the housing 14 does not need to have a sealed structure. Therefore, the boundary of the part divided | segmented into plurality may not be a sealing structure.

FIG. 4 is a diagram illustrating an example of a usage state of the toilet device 10.
The toilet device 10 is used in a state where the housing 14 is placed on the floor surface. The user uses the stool while sitting on the toilet seat 16. The waste excreted by the user is received by the toilet 12 (not shown), discharged through the toilet 12 to the cartridge in the housing 14, and stored in the cartridge. The cleaning water is supplied into the toilet 12 manually by the user. A user wash | cleans the inside of the toilet bowl 12 by throwing in wash water in the toilet bowl 12 from a bottle, a hose, etc. The filth here includes both small water and stool.

  On the upper surface of the toilet seat 16, an opening for allowing filth to pass therethrough and a seating surface 16 e for a user to sit across the left and right are formed. Although not shown, the upper surface has a long dimension in one direction (the left-right direction in FIG. 4; hereinafter referred to as the front-rear direction) in a plan view, and the other direction orthogonal to the one direction (the depth direction in FIG. 4; hereinafter, the left-right direction). It is formed to have an elliptical ring shape with a shorter dimension.

  The upper surface is formed in a curved shape that is convex upward. The upper surface is formed such that a gentle downward gradient is provided on the seating surface 16e as it goes from the central side in the left-right direction toward both outer sides. Thus, the user can easily sit in a posture in which both legs are placed on the left and right sides of the toilet seat 16 after straddling the seating surface 16e on the left and right. From this point of view, it may be formed so as to be convex upward.

  The outer peripheral surface portion 16d is formed to extend downward from the outer peripheral edge of the upper surface portion 16b, that is, from the outer peripheral portion of the upper surface portion 16b, and has a cylindrical shape. Although not shown, the outer peripheral surface portion 16d is formed to have an elliptical ring shape having a long dimension in the front-rear direction and a short dimension in the left-right direction in plan view.

  The upper surface is formed such that the surface portions on both sides in the left-right direction are positioned below the surface portions on both sides in the front-rear direction. Thereby, when the user sits on the seating surface 16e and uses the stool, the local part of the user is easily concealed by the surface portion in the front-rear direction, and so-called gold concealment effect is easily obtained.

  As shown in FIG. 4, the surface portions 16 da on both sides in the left-right direction of the outer peripheral surface portion 16 d are leg support portions that can apply the user's legs (particularly the thighs) when the user sits on the seating surface 16 e. It becomes. When the user sits on the seating surface 16e of the toilet seat 16 so as to stride from side to side, the leg pad 16da of the outer peripheral surface portion 16d is placed on both legs (in particular, with the soles of the legs on the floor). Can be pinched inside the thigh). Thereby, the direction around the vertical axis of the toilet device 10 can be held by both legs of the user. For this reason, if the user can hold the positions of both legs firmly by attaching the soles of both legs to the floor surface, the toilet apparatus 10 as a whole will be difficult to displace so as to swing around the vertical axis, and the user will be seated on the seating surface of the toilet seat 16. It becomes possible to use the stool while sitting stably at 16e. In order to obtain such operational effects, at least the outer peripheral surface portion 16d only needs to include the leg pad portion 16da. That is, the surface portions 16db on both sides in the front-rear direction of the outer peripheral surface portion 16d may be omitted.

  The leg pad 16da is formed so as to spread on both outer sides in the left-right direction as it goes downward. Thereby, it becomes easy to apply both legs of a user, and it becomes easy to pinch the leg contact part 16da firmly inside the user's both legs.

An example of how to use the toilet device 10 including the toilet seat 16 will be described.
In the case of a conventional Western-style toilet, the user first stands in a posture with his back facing the toilet device on the front side of the toilet device. Thereafter, the user walks rearward in this state and approaches the toilet device, and then sits down on the toilet seat. Thus, in order to sit on the toilet seat, the user needs to walk backward.

  In the case of the toilet device 10 according to the present embodiment, the user first takes a posture of standing on the rear side of the toilet device 10 (right side in FIG. 4) with the front facing the toilet device 10. Thereafter, the user walks forward (left side in FIG. 4) and approaches the toilet device 10, and then places both legs so as to straddle the seating surface 16 e of the toilet seat 16. Sit down on the face 16e. Thus, in the toilet device 10 according to the present embodiment, the user does not have to walk backward in order to sit on the toilet seat 16. At this time, the user sits with his / her legs on the leg rest 16da of the toilet seat 16 and rides on the toilet seat 16. After the stool is completed, the user rises up to stand away from the seating surface 16e of the toilet device 10, and then moves away from the toilet device 10 to the front side.

  In order to realize such usage, the toilet seat 16 and the toilet device 10 are configured so that there is no interference on the front and rear sides of the user when the user sits on the seating surface 16e. From another point of view, the toilet seat 16 and the toilet device 10 have a structure free of interfering objects so that when the user sits up from the seating surface 16e, the toilet seat 16 and the toilet apparatus 10 can move both before and after the user. Yes. Here, the interfering object refers to a portion protruding upward from the toilet seat 16 or the toilet apparatus 10.

  In addition, the above leg pad part 16da may set the height dimension from the outer peripheral part of the upper surface part 16b to a lower end part to 10 cm or more, for example. The upper limit value of the length may be set so as not to hit the floor, but may be set to 50 cm or less, for example. Further, the leg pad portion 16da is set so that the height dimension is longer than the left-right dimension of the surface portions on both sides in the left-right direction of the upper surface. Both are configurations from the viewpoint of making it easy to apply both legs of the user to the leg rest 16da.

  Moreover, the housing 14 is formed in a trapezoidal shape so as to spread on both sides in the left-right direction and both sides in the front-rear direction as it goes downward. Therefore, the housing 14 can be easily placed on the floor surface in a stable state, and the user can easily sit on the seating surface 16e of the toilet seat 16 supported by the housing 14 in a stable state. In addition, there is an effect that the user can easily sandwich the housing 14 with both legs.

FIG. 5 is an exploded view of the toilet device 10.
As for the toilet bowl 12, the toilet seat, the side surface, and the toilet bowl are integrally molded by materials, such as synthetic resins, such as polyethylene, for example. An opening for discharging filth to the cartridge is provided in the lower part of the toilet bowl 20. In the example shown in the figure, the opening is provided at substantially the center of the toilet seat. However, in another example, the opening may be arranged forward or rearward when the user sits on the toilet seat.

FIG. 6 is a side view of the cartridge 50.
In order to show the positional relationship between the cartridge 50 and the toilet bowl 12 and the housing 14, the toilet bowl 12 and the housing 14 are indicated by broken lines. The cartridge 50 includes a main body 52 capable of storing dirt therein, a handle 54 that can be gripped by a user when carrying the cartridge 50, and a lid 56 for closing the opening of the main body 52. . In use, the cartridge 50 is attached to the housing 14 with the lid 56 open. The mounting protrusion 60 provided on the bottom of the cartridge 50 is fitted into the mounting recess 62 provided on the bottom surface inside the housing 14, whereby the cartridge 50 is attached to the housing 14. The attachment protrusion 60 may not be provided, and in this case, the cartridge 50 may be attached to the housing 14 by fitting the main body 52 into the attachment recess 62. As shown in FIG. 5, the inside of the toilet 12 is hollow, but the lid 56 is slanted by a hinge or the like at an angle of about 100 ° to 160 ° in the opened state as shown in FIG. Since it is configured to be fixed, it can be stored in the cavity inside the toilet 12. Further, when the toilet 12 is attached to the housing 14, when the toilet 12 is not attached at a normal position and is attached in an inclined state, the lid 56 is caught on the toilet 12, so that the attachment position of the toilet 12 is determined. The user can be made aware that it is wrong. The angle of the lid 56 in the opened state may be an angle substantially parallel to the toilet bowl 20, for example. Similarly, the handle 54 is configured to be stored in a cavity inside the toilet 12. Further, the handle 54 and the lid 56 are provided at positions where the lid 56 and the handle 54 do not interfere with each other when the lid 56 is opened. In another example, the lid 56 may not be fixed to the upper surface of the cartridge 50 by a hinge or the like, and the lid 56 and the cartridge 50 may be configured independently. In this case, a pocket for storing the lid 56 when the lid 56 is removed may be provided in the toilet 12, the housing 14, the cartridge 50, or the like. For example, a pocket may be provided on the side surface of the cartridge 50. Thereby, interference with the lid | cover 56 and the toilet bowl 12 can be avoided, and when the toilet bowl 12 is attached to the housing 14, it can prevent that the toilet bowl 12 is caught in the lid | cover 56 and the lid | cover 56 breaks.

FIG. 7 is a perspective view of the cartridge 50 as viewed obliquely from above.
The handle 54 is provided along the rounded rectangular arc portion on the upper surface of the main body 52. As will be described later, the handle 54 also functions as a fixing portion for fixing the upper and lower cartridges 50 so that the relative positions of the upper and lower cartridges 50 do not shift when another cartridge 50 is stacked on the upper surface of the cartridge 50.

FIG. 8 is a perspective view of the cartridge 50 as viewed obliquely from below.
The attachment convex portion 60 is provided along the outer periphery on the lower surface of the main body 52. The mounting convex portion 60 is provided slightly inside the outer periphery of the lower surface of the main body 52, and when the mounting convex portion 60 is attached to the housing 14, the mounting convex portion 60 is inserted inside the mounting concave portion 62, and the upper surface of the mounting concave portion 62. Supports the peripheral edge portion of the lower surface of the main body 52.

9 and 10 are views showing a state where the cartridge 50 is attached to the housing 14. In FIGS. 9 and 10, the lid 56 is omitted.
A mounting convex portion 60 is provided on the bottom portion of the main body 52 of the cartridge 50 so that the outer peripheral shape is smaller than that of the other portions. The bottom surface on the inner side of the housing 14 matches the shape of the mounting convex portion 60. The cartridge 50 is attached to the housing 14 by being inserted into the provided attachment recess 62. It can be considered that the mounting convex portion 60 is configured to protrude from the bottom surface of the main body 52, or can be considered to be configured such that the outer peripheral portion of the bottom surface of the main body 52 is removed. As shown in the figure, the mounting recess 62 may be configured by forming a member constituting a wall surface on the outer periphery of the mounting recess 62, or may be configured as a recess on the inner bottom surface of the housing 14.

  The opening at the top of the housing 14 is formed in accordance with the shape of the top of the side surface of the main body 52 of the cartridge 50. As a result, the cartridge 50 is supported by the housing 14 at both the bottom and top and is stably positioned, so that the position of the cartridge 50 can be prevented from shifting during use. Further, in the example of this figure, the outer periphery of the main body 52 of the cartridge 50 is configured to become slightly smaller as it approaches the bottom, so that the cartridge 50 can be easily inserted into the opening of the housing 14 and inserted deeply. As a result, the cartridge 50 is gradually positioned at the correct position by the opening of the housing 14, so that the mounting convex portion 60 can be easily fitted into the mounting concave portion 62.

  When taking out the cartridge 50 from the housing 14, the user may hold the handle 54 and pull the cartridge 50 upward. As will be described later, since the valve is provided at the opening of the cartridge 50, even when the cartridge 50 is taken out, dirt, odor, etc. stored inside are hardly discharged to the outside. After the cartridge 50 is taken out, the opening can be closed by closing the lid 56.

FIG. 11 is a diagram illustrating a state where the cartridges 50 are stacked.
As described above, the handle 54 is provided along the outer periphery of the upper surface of the main body 52, but the side surface of the main body 52 is configured to be slightly smaller as it approaches the bottom, that is, slightly narrow. The bottom of 52 is configured so that the shape just matches the inner periphery of the handle 54. Therefore, when the cartridge 50a and the cartridge 50b are stacked one above the other, the bottom of the main body 52b of the upper cartridge 50b is just inserted between and engaged with the two handles 54a of the lower cartridge 50a. The relative position is fixed so as not to shift. That is, the handle 54a is configured to be engageable with the lower portion of the main body 52b of another cartridge 50b. Accordingly, when the cartridge 50 is transported, the plurality of cartridges 50 can be stably stacked and transported.

FIG. 12 is a perspective view of the upper surface portion 64 of the cartridge 50 as viewed obliquely from below.
The upper surface portion 64 is configured to be detachable with respect to the main body 52, and a valve mounting portion 66 for mounting the valve 28 is provided along an opening disposed substantially at the center of the upper surface portion 64. When attaching the valve 28, the valve 28 is attached so as to cover the valve attachment portion 66 from the outside through the upper opening of the valve 28, and the valve 28 is fastened to the inner valve attachment portion 66 from the outside of the valve 28 with an annular fastening member. Fix it.

13 and 14 schematically show a mechanism for attaching the valve 28 to the cartridge 50.
FIG. 13 is a schematic vertical sectional view in the vicinity of the valve mounting portion 66. The upper opening of the cartridge 50 is larger than the opening of the toilet bowl 20, and the toilet bowl 20 and the cartridge 50 are installed so that the upper surface of the cartridge 50 cannot be seen when viewed from above. Further, the toilet bowl 20 and the cartridge 50 are installed so that the opening of the toilet bowl 20 is inserted into the opening of the cartridge 50 so that the lower end of the opening section of the toilet bowl 20 is lower than the upper end of the opening section of the cartridge 50. . Thereby, it is possible to prevent the upper surface of the cartridge 50 from being soiled by the filth introduced from the toilet bowl 20 into the cartridge 50. The valve 28 is fastened by a fixing member 67 from the outside of the valve mounting portion 66 provided on the lower side of the upper surface portion of the cartridge 50, and is fixed to the valve mounting portion 66. As shown in FIG. 14, the valve mounting portion 66 may be provided with a locking portion 65 for locking the upper end of the valve 28, and the upper end of the valve 28 may be locked to the locking portion 65.

FIG. 15 schematically illustrates another mechanism for attaching the valve 28 to the cartridge 50.
In the example of this figure, a valve mounting portion 68 for locking the valve 28 is provided above the upper surface portion of the cartridge 50, and the upper end of the valve 28 is locked to the valve mounting portion 68. Thereby, since the valve 28 can be attached and detached without removing the upper surface part of the cartridge 50, the convenience for the user can be improved. Further, since the valve 28 is provided between the toilet bowl 20 and the upper surface portion of the cartridge 50, filth and the like can be prevented from leaking from the gap between the toilet bowl 20 and the cartridge 50 to the upper surface of the cartridge 50.

FIG. 16 schematically illustrates yet another mechanism for attaching the valve 28 to the cartridge 50.
In the example of this figure, similarly to the example of FIG. 15, the upper end of the valve 28 is locked to the valve mounting portion 68 provided on the upper side of the upper surface portion of the cartridge 50. 51 is made parallel to the toilet bowl 20 instead of vertical. As a result, the gap between the toilet bowl 20 and the cartridge 50 can be further narrowed, so that liquid such as small water or washing water bounces back into the gap between the toilet bowl 20 and the cartridge 50, and the upper surface of the cartridge 50. Etc. can be prevented from getting dirty. Further, since the valve 28 can be attached and detached without removing the upper surface portion of the cartridge 50, the convenience for the user can be improved.

FIG. 17 schematically illustrates yet another mechanism for attaching the valve 28 to the cartridge 50.
In the example of this figure, as in the example of FIG. 16, the folding surface 51 at the periphery of the opening of the cartridge 50 is not vertical but parallel to the toilet bowl 20. After the upper end of the valve 28 is matched, the valve 28 is fixed to the upper surface of the cartridge 50 by pressing the upper end of the valve 28 against the upper surface and the folding surface 51 of the cartridge 50 from above with a fixing member 69 that is matched to the shape of the opening. To do. This also makes it possible to further narrow the gap between the toilet bowl 20 and the cartridge 50, so that liquid such as small water or washing water bounces back and enters the gap between the toilet bowl 20 and the cartridge 50. It is possible to prevent the upper surface and the like from becoming dirty. Further, since the valve 28 can be attached and detached without removing the upper surface portion of the cartridge 50, the convenience for the user can be improved.

FIG. 18 is a diagram schematically showing the configuration of the valve 28.
The valve 28 is configured by a pair of seal walls 32a and 32b (both are collectively referred to as a seal wall 32) that are arranged so that the inner side surfaces thereof face each other on the left and right. Each seal wall 32 is formed of a material having flexibility and stretchability. In the present embodiment, silicon rubber is used as a flexible material. Silicone rubber is also a material that is durable and hydrophilic to dirt caused by dirt. Each seal wall 32 is bonded at the upper bonding portion 70 at both ends, and the uppermost portion constitutes a supported portion 72 to be attached to the valve attachment portion 66. As the supported portion 72, a member formed of a synthetic resin or the like according to the shape of the valve mounting portion 66 may be bonded to the valve 28. Thereby, the valve 28 can be easily attached to the valve attachment portion 66. The lower portions of the seal walls 32 are separated without being bonded, and slit-like filth discharge holes 26 are formed therein.

  Although the lower part of each seal wall 32 is not mutually adhere | attached, when using the toilet device 10, since the small water as a waste, washing water, etc. will pass the inner side of the valve 28, the lower part of each seal wall 32 is used. In the filth discharge hole 26 to be formed, their inner side surfaces are in close contact with each other due to the surface tension of water. As a result, the filth discharge hole 26 can be closed, and the odor due to the filth in the cartridge 50 can be prevented from leaking from the filth discharge hole 26 to the outside. Further, by closing the filth discharge hole 26, the inside of the cartridge 50 located behind the filth discharge hole 26 can be prevented from being seen from the opening of the toilet 12, so that the user can comfortably place the toilet apparatus 10 in the toilet 50. Can be used.

  FIG. 19 is a view for explaining the operation of the valve 28. FIG. 19A shows a state where stool Pa is stored as filth in the bottom of the valve 28, and FIG. 19B shows a state where urine Pb is stored in addition to the stool Pa.

  As shown in FIG. 19 (a), when filth is introduced into the toilet bowl 20 of the toilet bowl 12, the filth passes through the opening at the top of the cartridge 50 from the opening at the bottom of the stool 20, It is guided by its own weight or water flow to the vicinity of the inlet 26a of the discharge hole 26. When filth accumulates on the inner bottom surface around the inlet 26a of the filth discharge hole 26, the pair of seal walls 32 is given a spreading force Fa that pushes and spreads the filth discharge hole 26 by the weight of the filth. This spreading force Fa increases as more dirt accumulates in the bottom of the valve 28. When the pushing force Fa increases, the pair of seal walls 32 are elastically deformed so as to widen the inner width dimension of the filth discharge hole 26 as shown in FIG. As a result, the dirt discharge hole 26 is opened, and the dirt stored in the bottom of the valve 28 is discharged into the main body 52 of the cartridge 50 through the dirt discharge hole 26.

  The pair of seal walls 32 is provided with a closing force Fb that closes the filth discharge hole 26 by surface tension caused by water between the seal walls 32 and its own elastic repulsion. When the filth in the bottom of the valve 28 is discharged, the closing force Fb restores the shape of the pair of seal walls 32 so as to narrow the inner width of the filth discharge hole 26, and the filth discharge hole 26 is closed. Become. Thus, the valve structure formed by the pair of seal walls 32 can open the filth discharge hole 26 by the weight of the object stored in the bottom of the valve 28.

  As described above, when the toilet device 10 is used, if the weight of the filth is sufficient, the pair of seal walls 32 can be opened by the weight of only the filth to discharge the filth. However, the weight of the filth may be insufficient. For this reason, in this case, the filth may be discharged by directly supplying cleaning water from a bottle or the like. Thus, when discharging filth by supplying washing water, a pair of seal walls 32 are configured to open when 10 g to 100 g of washing water is introduced from the viewpoint of reducing the amount of washing water used. May be. In this configuration, the thickness, hardness, and the like of each seal wall 32 may be adjusted. For example, silicon rubber having a hardness of 0 to 20 °, more preferably a hardness of 0 to 10 ° may be used as the seal wall 32.

  In the valve 28 shown in FIG. 18, the lower part of the seal wall 32 is not bonded, and therefore, the filth discharge hole 26 is easily opened as compared with the case where the lower part of the seal wall 32 is bonded. Thereby, when filth is thrown in, the situation where filth is blocked up without opening filth discharge hole 26 can be reduced. However, on the contrary, since the lower part of the seal wall 32 is not adhered, after the filth passes through the filth discharge hole 26, the filth discharge hole 26 cannot be closed, and the state where the filth discharge hole 26 is kept open after that occurs. There are concerns. In order to solve the problem of reducing such a situation, the present inventors have searched for a suitable structure of the seal wall 32 and repeated experiments, and as a result, have arrived at a valve having a structure as shown in FIG. .

20 and 21 are diagrams schematically showing the structure of another example of the valve 80. FIG.
In the valve 80 shown in this figure, both ends of the seal wall 32 are lifted upward at the lifted positions 82 of the adhesive portions 70 at both ends of the seal wall 32, and are attached to the cartridge 50 while maintaining the lifted state. In order to realize this state with a simple configuration, in the valve 80 shown in FIG. 20, the seal wall 32 is lifted from the same side at the lifted positions 82 at both ends of the seal wall 32, so that It is bent and pinched so that the inner surface of 32 abuts. In order to maintain this state, for example, the seal wall 32 may be pinched with a clip or the like, or may be fixed with staples or the like in the pinched state. Both ends of each seal wall 32 are lifted upward, but the vicinity of the center bends due to its own weight. Therefore, the filth discharge hole 26 at the lower end is curved in a curved shape with both ends being high and the vicinity of the center being low.

  21A is a side view of the valve 28 shown in FIG. 18, and FIG. 21B is a side view of the valve 80 shown in FIG. In the valve 28, each seal wall 32 forms a plane parallel to the vertical surface. In the valve 80, each seal wall 32 is pulled upward at the lifted position 82, so that the seal below the lifted position 82 is sealed. The wall 32 curves to the opposite side of the pinched direction, and becomes a convex curve toward the pinched direction in a side view, and the filth discharge hole 26 at the lower end is lifted slightly upward.

  FIG. 21C is a plan view of the valve 28 shown in FIG. 18 viewed from below, and FIG. 21D is a plan view of the valve 80 shown in FIG. 20 viewed from below. In the valve 28, each seal wall 32 is a straight line parallel to the long axis of the opening of the cartridge 50 in a plan view when the valve 28 is attached to the cartridge 50, but in the valve 80, as described above. The seal wall 32 below the lifting position 82 is curved to the opposite side of the pinched one, and the degree of the curve is larger at the pinched position, that is, at both ends than near the center. The seal wall 32 has a curved curve that is convex in a pinched direction in a plan view when the valve 28 is attached to the cartridge 50.

  As described above, each seal wall 32 has a curved shape that protrudes in the horizontal direction or obliquely downward on the pinched side in the region below the lifting position 82 including at least the lower end. Since the closing force between the walls 32 is close to that of the valve 28, the sealing walls 32 are in close contact with each other and are easily closed even after the filth passes and is opened, and the filth discharge hole 26 is not closed. The situation of being kept open can be reduced.

  Although FIG. 20 shows an example in which both the pair of seal walls 32 are pinched and lifted, in another example, only one seal wall 32 may be lifted. Also in this case, as a result of the raised seal wall 32a having a curved shape protruding in the horizontal direction or obliquely downward on the pinched side, the other seal wall 32b is also pushed by the seal wall 32a. It becomes a shape and it can be set as the shape which is easy to adhere | attach with the seal wall 32a.

  FIG. 22 is a reference photograph of an example of the valve 80 shown in FIG. In FIG. 22, the front side of the upper surface of the seal wall 32 is picked up, and the lower part of the seal wall 32 has a curved surface that protrudes obliquely downward on the front side of the pinched paper surface. The lower end of the seal wall 32 has a curved shape with both ends being high and the vicinity of the center being low.

  FIG. 23 is a schematic cross-sectional view showing a state where filth is stored in the cartridge 50. When the toilet device 10 is used, normally, as shown in FIG. 23 (a), liquids such as small water and washing water are more than solids, so some solids float in the liquid, and some The solids are sinking. When the liquid level reaches the lower end of the valve 28, the sealing wall 32 is pushed up by the liquid level as shown in FIG. If it continues to be used in this state, the filth that could not pass through the filth discharge hole 26 accumulates in the valve 28, and odor leaks from the opening of the cartridge 50. Therefore, a mechanism is required to make the user aware that the storage state of the filth in the cartridge 50 reaches the upper limit and the filth must be discarded or the empty cartridge 50 needs to be replaced.

  For example, the sealing wall 32 may be made of a transparent or translucent material that transmits at least a part of visible light, and the storage state of the filth may be recognized by a color change. Further, a mark or an image indicating that the storage state of the filth has reached the upper limit is provided at a position inside or outside the seal wall 32 where the seal wall 32 can be visually recognized from above when pushed up by the filth. May be. When this mark is provided inside the seal wall 32, the seal wall 32 may be made of an opaque material. When this mark is provided outside the seal wall 32, the seal wall 32 is made of a transparent or translucent material.

  As shown in FIG. 23B, when filth is stored in the cartridge 50 and the seal wall 32 is pushed up by the filth, the lower end of the seal wall 32 is originally lifted slightly upward, The filth discharge hole 26 is always closed. Accordingly, even if the cartridge 50 is shaken or falls while the cartridge 50 is being transported in order to discard the filth, the filth in the cartridge 50 can be prevented from leaking outside. Further, even when a large amount of water enters the toilet apparatus 10 due to flooding or water leakage while the toilet apparatus 10 is in use, water accumulates in the cartridge 50 and the seal wall 32 is pushed up. When this is done, the filth discharge hole 26 is closed, so that the filth stored in the cartridge 50 can be prevented from being discharged to the outside.

The effect of the toilet device 10 will be described.
As described above, since the valve 80 has flexibility, it has the following advantages. Consider a case in which the filth introduced into the valve 80 stops on a part of the inner surface without being guided to the entrance of the filth discharge hole 26 at the bottom. According to the present embodiment, even in this case, when the filth is received at the other portion of the valve 80, the other portion is flexed and deformed, so that the portion on which the filth is placed easily follows and deforms. As a result, the filth that has stopped at a part of the valve 80 is easy to move, and the filth is easily guided to the bottom of the valve 80.

  Further, even if stool adheres to the inner surface of the valve 80, the stool is easily peeled off from the attachment position by being deformed so that the valve 80 is pulled. From this point also, sewage is easily guided to the bottom of the valve 80. Become.

  Further, since the valve 80 has flexibility, the entire valve 80 can be vibrated when washing water or the like is poured into the toilet bowl 20 to flow filth or when it rises from the toilet seat 16 of the toilet device 10. it can. In particular, since the valve 80 is hung from the cartridge 50, the entire valve 80 is particularly easily vibrated. This vibration makes it easier for the filth in the valve 80 to move, and also from this point it is easier to guide the filth to the bottom of the valve 80.

  As a result, the filth in the valve 80 can be easily discharged from the filth discharge hole 26 at the bottom of the valve 80.

  In addition, since it becomes easy to guide the filth to the bottom of the valve 80 in this way, the filth is less likely to remain in the valve 80. As a result, the amount of cleaning water used to clean the inner surface of the valve 80 can be suppressed. Therefore, the toilet device 10 suitable for use in an environment where the water supply cannot be used can be provided.

  Further, since the valve 80 has flexibility, it is difficult to repel when the valve 80 receives filth, particularly urine. Therefore, it is possible to prevent the filth from splashing back and splashing around and hitting the user.

  Further, since the valve 80 is constituted by a pair of seal walls 32 that open and close the filth discharge hole 26 by contacting and separating the inner side surfaces of each other, the valve 80 can be realized with a simple structure, and the manufacturing cost is reduced. be able to.

  In the present embodiment, since the pair of seal walls 32 is constituted by the separated sheet bodies, the pair of seal walls 32 can move greatly without restricting movement of each other. Therefore, the opening when the pair of seal walls 32 is opened can be increased, and a large amount of waste can be discharged early.

  As mentioned above, although this invention was demonstrated based on embodiment, embodiment only shows the principle and application of this invention. In the embodiment, many modifications and arrangements can be made without departing from the spirit of the present invention defined in the claims.

  Although the seal wall 32 has been described as an example using silicon rubber as a material, any material having flexibility may be used. For example, a synthetic resin such as a fluorine resin or an olefin resin may be used.

  In the embodiment, the housing 14 has been described as an example of a support that supports the toilet 12. The support may not be portable with the toilet 12 such as the housing 14. For example, the support may be a fixed structure such as the floor of a flush toilet.

  In the embodiment, the example in which the valve 80 is detachably attached to the cartridge 50 has been described. The valve 80 may be detachably attached to the toilet 12 or the housing 14.
