Toilet, toilet seat, and toilet device

Abstract

A toilet includes a toilet bowl part with a waste discharge hole formed on its bottom part and also includes a valve structure capable of opening and closing the waste discharge hole, and the toilet bowl part is formed of a material having flexibility. Accordingly, the toilet bowl part is easily bent by waste brought into the toilet bowl part. When the toilet bowl part is bent while waste is accumulated in the bottom part of the toilet bowl part, a gradient on an inner surface of the toilet bowl part becomes larger, so that the waste can be easily led to the bottom part of the toilet bowl part.

What is claimed is: 
     
         1 . A toilet, comprising:
 a toilet bowl part with a waste discharge hole formed on a bottom part thereof, the toilet bowl part including a waste leading part that receives waste and leads the waste to the waste discharge hole; and   a valve structure capable of opening and closing the waste discharge hole, wherein the waste leading part has flexibility.   
     
     
         2 . The toilet of  claim 1 , wherein the valve structure is constituted by a pair of seal wall parts of which the inner surfaces are arranged to face each other and are contacted and separated with each other so as to close and open the waste discharge hole. 
     
     
         3 . The toilet of  claim 2 , wherein the pair of seal wall parts are integrally formed with the waste leading part. 
     
     
         4 . The toilet of  claim 2 , further comprising a position maintaining structure that maintains the state in which one seal wall part of the pair of seal wall parts is surmounted by the other seal wall part. 
     
     
         5 . The toilet of  claim 4 , wherein, when the waste discharge hole is opened, the pair of seal wall parts are elastically deformed so that the lower ends thereof are directed from an initial position, in which the one seal wall part is surmounted by the other seal wall part, toward the vertically downward direction. 
     
     
         6 . The toilet of  claim 4 , wherein the position maintaining structure is a lifting member that lifts the pair of seal wall parts so as to maintain the state in which the one seal wall part is surmounted by the other seal wall part. 
     
     
         7 . The toilet of  claim 2 , wherein, to contact/separation portions of the pair of seal wall parts, elastic repulsion, by which the contact/separation portions push each other, is applied. 
     
     
         8 . A toilet device, comprising:
 the toilet of  claim 1 ; and   a support body that supports the toilet, wherein:   the toilet includes a supported part provided on an outer peripheral side of the toilet bowl part; and   the support body includes an opening part into which the toilet bowl part is inserted, and a toilet receiving part that receives the supported part.   
     
     
         9 . The toilet device of  claim 8 , wherein:
 one of the supported part and the toilet receiving part includes an annular wall part protruding toward the other thereof, and an annular click part protruding in one side of radial direction of the annular wall part; and   the annular click part is engaged with part of the other of the supported part and the toilet receiving part so as to prevent the toilet bowl part from coming out through the opening part.   
     
     
         10 . The toilet device of  claim 8  wherein:
 one of the supported part and the toilet receiving part includes a fitting projection part formed annularly; and 
 the other of the supported part and the toilet receiving part includes a fitting recess part into which the fitting projection part is press-fitted. 
 
     
     
         11 . The toilet device of  claim 10 , wherein the fitting recess part is formed in an annular groove shape. 
     
     
         12 . A toilet seat, comprising:
 an upper surface part including an opening through which waste is made to pass, and an seating surface on which a user is to straddle to sit; and   leg placement parts that are formed to extend downward from outer periphery parts on both the left and right sides of the upper surface part, and on which the both legs of a user are to be placed, respectively.   
     
     
         13 . The toilet seat of  claim 12 , wherein the leg placement parts are formed so as to extend outward in the respective lateral directions as approaching a lower side. 
     
     
         14 . The toilet seat of  claim 12 , further comprising an inner peripheral surface part formed to extend downward from an inner periphery of the upper surface part. 
     
     
         15 . The toilet seat of  claim 14 , wherein a lower edge part of the inner peripheral surface part can be fitted into an upper edge part of a toilet bowl part of a toilet. 
     
     
         16 . A toilet device, comprising:
 a toilet that receives waste;   a support body that supports the toilet; and   the toilet seat of  claim 12  supported by the support body.
