Toilet bowl device

Abstract

To provide a toilet bowl device allowing bubbles to be discharged with ease even in a case where a bowl is supplied with the bubbles. In a toilet bowl device, a control unit executes a pre-jet washing step for bubbles of supplying wash water to a bowl via a jet discharge port and a pre-rim washing step for bubbles of supplying wash water to the bowl via a rim discharge port after the pre-jet washing step for bubbles is initiated in a case where bubbles are present on a stored water surface.

What is claimed is: 
     
         1 . A toilet bowl device comprising:
 a bowl having a rim discharge port in an upper portion of the bowl and having a jet discharge port in a bottom portion of the bowl;   a rim wash water supply device supplying wash water to the bowl via the rim discharge port;   a jet wash water supply device supplying wash water to the bowl via the jet discharge port;   a drain trap provided on a toilet bowl drain path from the bottom portion of the bowl to a drain pipe and determining a height of a stored water surface of wash water collected in the bottom portion of the bowl by performing water sealing on the toilet bowl drain path; and   a control unit controlling the rim wash water supply device and the jet wash water supply device,   wherein, in a case where bubbles are present on the stored water surface, the control unit executes   a pre jet washing step for bubbles of supplying wash water to the bowl via the jet discharge port and   a pre-rim washing step for bubbles of supplying wash water to the bowl via the rim discharge port after the pre-jet washing step for bubbles is initiated.   
     
     
         2 . The toilet bowl device according to  claim 1 , wherein, in a case where bubbles are present on the stored water surface, the control unit supplies wash water to the bowl via the jet discharge port to an extent that the toilet bowl drain path is torn in the pre-jet washing step for bubbles. 
     
     
         3 . The toilet bowl device according to  claim 1 , wherein, in a case where bubbles are present on the stored water surface, the control unit executes the pre-rim washing step for bubbles before the pre-jet washing step for bubbles is terminated. 
     
     
         4 . The toilet bowl device according to  claim 1 , wherein, in a case where the control unit performs the control in a standard mode in which washing is performed with bubbleless wash water, the control unit executes
 a standard mode pre-rim washing step of supplying wash water to the bowl via the rim discharge port,   a standard mode jet washing step of supplying wash water to the bowl via the jet discharge port after the standard mode pre-rim washing step is initiated, and   a standard mode post-rim washing step of supplying wash water to the bowl via the rim discharge port after the standard mode pre-rim washing step is terminated and the standard mode jet washing step is initiated, and   the pre-rim washing step for bubbles is longer in time than the standard mode pre-rim washing step.   
     
     
         5 . The toilet bowl device according to  claim 1 , wherein a post-jet washing step for bubbles of supplying wash water to the bowl via the jet discharge port after the pre-jet washing step for bubbles is terminated and the pre-rim washing step for bubbles is initiated and
 a post-rim washing step for bubbles of supplying wash water to the bowl via the rim discharge port after the pre-rim washing step for bubbles is terminated and the post-jet washing step for bubbles is initiated are further executed.   
     
     
         6 . The toilet bowl device according to  claim 5 , wherein, in a case where bubbles are present on the stored water surface, the control unit causes the stored water surface to be coated with bubbles by the post-rim washing step for bubbles being executed after a height of the stored water surface is lowered by the post-jet washing step for bubbles being executed.
