Hygienic toilet

Abstract

Disclosed herein is a hygienic toilet. The hygienic toilet includes: a toilet body; a lower seat; an upper seat configured to be disposed on the top of the lower seat and to rotate; a rotation drive unit configured to rotate the upper seat; a seat movement unit including: a link member coupled such that the lower portion of the link member is hinged to the back portion of the toilet body in a state in which the upper portion of the link member has been hinged to the back portion of the lower seat; and a link member spring configured to apply elastic force to the link member; a cleaning unit configured to be mounted on the toilet body; and a movement delay unit configured to move the upper seat a standby location between the cleaning location and the seating

What is claimed is: 
     
         1 . A hygienic toilet comprising:
 a toilet body;   a lower seat configured in a shape a center of which is open, and configured to be disposed on a top of the toilet body;   an upper seat configured in a ring shape, and configured to be disposed on a top of the lower seat and to rotate based on a center of the lower seat;   a rotation drive unit configured to rotate the upper seat;   a seat movement unit including: a link member coupled such that a lower portion of the link member is hinged to a back portion of the toilet body so that it can be rotated around a horizontal axis in a state in which an upper portion of the link member has been hinged to a back portion of the lower seat so that it can be rotated around a horizontal axis; and a link member spring configured to apply elastic force to the link member;   a cleaning unit configured to be mounted on the toilet body in a corresponding state above a back of the upper seat so as to clean a surface of the upper seat while the upper seat is being rotated by the rotation drive unit after being moved to the cleaning location; and   a movement delay unit configured to move the upper seat from the cleaning location to a standby location between the cleaning location and the seating location, and to delay movement of the upper seat.   
     
     
         2 . The hygienic toilet of  claim 1 , wherein the movement delay unit comprises:
 a pressing lever configured such that a lower portion thereof is coaxially and rotatably coupled to a lower hinge coupling center of the link member in a state in which an upper portion of the pressing lever corresponds to a center portion of the link member;   a pressing lever spring configured to apply elastic force to the pressing lever in a direction in which the pressing lever presses the link member;   a guide roller configured to be laterally and horizontally disposed above the pressing lever and to be supported on the toilet body;   a wire configured such that in a state in which the wire has been wound around the guide roller so that the upper seat can be maintained at the standby location, one end of the wire is fastened to the pressing lever and a remaining end of the wire is fastened to the link member; and   air cushions configured to delay rotation of the pressing lever when the pressing lever is rotated in a pressing direction.   
     
     
         3 . A hygienic toilet comprising:
 a toilet body;   a lower seat configured in a shape a center of which is open, and configured to be disposed on a top of the toilet body;   an upper seat configured in a ring shape, and configured to be disposed on a top of the lower seat and to rotate based on a center of the lower seat;   a rotation drive unit configured to rotate the upper seat;   a link member coupled such that a lower portion of the link member is hinged to a back portion of the toilet body so that it can be rotated around a horizontal axis in a state in which an upper portion of the link member has been hinged to a back portion of the lower seat so that it can be rotated around a horizontal axis;   a cleaning unit configured to be mounted on the toilet body in a corresponding state above a back of the upper seat so as to clean a surface of the upper seat while the upper seat is being rotated by the rotation drive unit after being moved to the cleaning location; and   a link member drive unit configured to reciprocate the upper seat between the seating location and the cleaning location as the link member is rotated around the lower portion in a front-back direction, and to maintain the upper seat for a set cleaning time in a state in which the upper seat has been moved to the cleaning location.   
     
     
         4 . The hygienic toilet of  claim 1 , wherein the cleaning unit comprises:
 a cleaning case formed in a shape a bottom of which is open, and configured to be mounted on the toilet body;   a cleaning nozzle configured to be controlled such that it sprays a cleaning solution onto a surface of the upper seat inside the cleaning case when the upper seat has been moved to the cleaning location;   a cleaning brush configured to be disposed behind the cleaning nozzle within the cleaning case based on a rotation direction of the upper seat, and configured to clean the surface of the upper seat and also remove a cleaning solution while the upper seat is being rotated; and   a drying brush configured to be disposed behind the cleaning brush inside the cleaning case based on the rotation direction of the upper seat  130 , and configured to remove moisture from the surface of the upper seat.   
     
     
         5 . The hygienic toilet of  claim 3 , wherein the cleaning unit comprises:
 a cleaning case formed in a shape a bottom of which is open, and configured to be mounted on the toilet body;   a cleaning nozzle configured to be controlled such that it sprays a cleaning solution onto a surface of the upper seat inside the cleaning case when the upper seat has been moved to the cleaning location;   a cleaning brush configured to be disposed behind the cleaning nozzle within the cleaning case based on a rotation direction of the upper seat, and configured to clean the surface of the upper seat and also remove a cleaning solution while the upper seat is being rotated; and   a drying brush configured to be disposed behind the cleaning brush inside the cleaning case based on the rotation direction of the upper seat  130 , and configured to remove moisture from the surface of the upper seat.
