Flush toilet

Abstract

A flush toilet includes: a main toilet unit having a bowl portion and a discharge trap pipe; a jet spout port; a jet water conduit configured to supply flush water to the jet spout port, a tank configured to temporarily store the flush water; and a pump configured to pump up the flush water stored in the tank. The jet water conduit has a downstream side water conduit extending to the jet spout port and an upstream side water conduit connected to the downstream side water conduit. The downstream side water conduit is made of porcelain. The sucking-up portion and the pump are positioned on one side with respect to the discharge trap pipe in a left-and-right direction. A connecting portion between the upstream side water conduit and the downstream side water conduit is also positioned on the same one side with respect to the discharge trap pipe.

What is claimed is: 
     
         1 . A flush toilet comprising:
 a main toilet unit having a bowl portion and a discharge trap pipe extending from a lower part of the bowl portion;   a jet spout port configured to spout out flush water into an inside of the discharge trap pipe in a rearward direction;   a jet water conduit configured to supply the flush water to the jet spout port,   a tank configured to temporarily store the flush water; and   a pump configured to pump up the flush water that has been stored in the tank through a sucking-up portion of the tank;   wherein   the jet water conduit has a downstream side water conduit extending to the jet spout port and an upstream side water conduit connected to the downstream side water conduit,   the downstream side water conduit is made of porcelain,   the sucking-up portion and the pump are positioned on one side with respect to the discharge trap pipe in a left-and-right direction, and   a connecting portion between the upstream side water conduit and the downstream side water conduit is also positioned on the same one side with respect to the discharge trap pipe in the left-and-right direction as the sucking-up portion and the pump.   
     
     
         2 . The flush toilet according to  claim 1 , wherein
 the sucking-up portion is open in a direction that is aligned in a front-and-rear direction, and   the connecting portion between the upstream side water conduit and the downstream side water conduit extends in the front-and-rear direction.   
     
     
         3 . The flush toilet according to  claim 1 , wherein
 the sucking-up portion is formed by coupling a connecting surface of a tank side pipe and a connecting surface of a pump side pipe,   the connecting portion between the upstream side water conduit and the downstream side water conduit is formed by coupling a connecting surface of the upstream side water conduit and a connecting surface of the downstream side water conduit, and   the connecting surface of the tank side pipe, the connecting surface of the pump side pipe, the connecting surface of the upstream side water conduit and the connecting surface of the downstream side water conduit are aligned in parallel with each other.   
     
     
         4 . The flush toilet according to  claim 1 , wherein
 a flow direction of the flush water when the flush water passes through the sucking-up portion is a front-and-rear direction, and   a flow direction of the flush water when the flush water passes through the connecting portion between the upstream side water conduit and the downstream side water conduit is also a front-and-rear direction.   
     
     
         5 . The flush toilet according to  claim 1 , wherein
 the connecting portion between the upstream side water conduit and the downstream side water conduit is located below the bowl portion, and   the sucking-up portion is also located below the bowl portion.   
     
     
         6 . The flush toilet according to  claim 1 , wherein
 a water conduit from the sucking-up portion to the connecting portion between the upstream side water conduit and the downstream side water conduit is all positioned on the same one side with respect to the discharge trap pipe in the left-and-right direction as the sucking-up portion and the pump.   
     
     
         7 . The flush toilet according to  claim 6 , wherein
 a water path from the sucking-up portion to the connecting portion between the upstream side water conduit and the downstream side water conduit is all positioned in such a manner that the water path does not overlap with the discharge trap pipe in a plan view.   
     
     
         8 . The flush toilet according  claim 7 , wherein
 a water conduit from the sucking-up portion to the connecting portion between the upstream side water conduit and the downstream side water conduit is all positioned lower than a rim portion.
