Drain hose and toilet system using the same

Abstract

A water control tubular portion is fixed to the forward end of a discharge hose body. The water control tubular portion is a tubular body or an inverted funnel-like (trumpet-like) tubular body and has water control sections inside it. The water control sections are arranged zigzag so that the amount of discharge of an object (e.g. sewage) becomes as constant as possible and the speed of the discharge can be made slackened. Since the amount of discharge of the object from the forward end of the discharge hose body becomes substantially constant by the water control tubular section and the speed (flow speed) of the discharge is slackened, the forward end of the discharge hose is not fluttered by the pressure of a fluid object (sewage) sent under pressure from a simple toilet device.

1 - 5 . (canceled) 
   
   
       6 . A drain hose comprising:
 a hose body; and   a tubular water control portion which is attached to a tip end of the hose body,   wherein the tubular water control portion includes a plurality of water control pieces disposed therein.   
   
   
       7 . The drain hose according to  claim 6 , wherein the tubular water control portion is a tubular member or a reverse-funnel like tube and contains a plurality of water control pieces inside thereof with the water control pieces being arranged in a staggered manner. 
   
   
       8 . A toilet system wherein the toilet system is constituted of an existing toilet and a portable toilet device,
 wherein a drain hose for draining excrement is connected to the portable toilet device; and   wherein a tubular water control portion which is attached to a tip end of the drain hose is fixed to an inside of the existing toilet through a space between a toilet device and a toilet seat of the existing toilet.   
   
   
       9 . The toilet system according to  claim 8 , wherein the portable toilet device is a pressurizing type flush toilet; and
 the portable toilet device contains:
 a toilet device body that includes a water-supplying nozzle which supplies rinse water from the vicinity of an opening portion of a toilet device, a stagnant portion which is disposed at the deep place thereof under the opening portion, and a draining port which communicates with the stagnant portion and is connected with the drain hose; 
 breaking means for breaking the excrement, the breaking means being disposed in the stagnant portion; 
 pressurizing delivery means of broken substance for delivering the broken substance of the excrement with pressure, the pressurizing delivery means being disposed at the upper part of the stagnant portion; and 
 a lid for open and closure which closes the stagnant portion tightly, the lid being disposed at the upper side of the pressurizing delivery means of broken substance. 
   
   
   
       10 . The toilet system according to  claim 9 , wherein an on-off valve mechanism is disposed in the vicinity of the draining port; and
 by opening the on-off valve mechanism when the pressurizing delivery means of broken substance is driven and inner pressure of a space formed by the lid for open and closure and the stagnant portion exceeds a predetermined pressure, the excrement of the portable toilet is delivered with pressure towards a side of the toilet device of the existing toilet.
