JPH06299579A - Waste branch pipe of kitchen base - Google Patents

Abstract

PURPOSE:To simplify a piping construction work by joining a waste branch pipe, which is formed so as to be connectable to a waste pipe of bellows pipe and to a waste pipe of polyvinyl chloride pipe as well, to an outlet pipe of a waste water trap d connecting a waste water hose of a tableware washing device or the like provided near a kitchen base to the trap through the waste branch pipe. CONSTITUTION:A waste branch pipe 6 (pipe joint with branch) having a hose connection 16 on one end thereof and having therein a baffle 18 interconnects an outlet pipe 12 of a waste water trap 5 of a kitchen base sink and a waste water bellows hose 7. And when a polyvinyl chloride pipe is used as a waste water pipe, the bellows hose connection 16 is cut off to connect it to the waste branch pipe. Next, a waste water hose 9 of an accessory device 4 such as a tableware washing device provided near a kitchen base is connected to a branch pipe 17 of the branch pipe 6 to discharge waste water together with the waste water from a sink. As a result, piping construction work can be simplified and hence installation cost can be reduced.

It is a drain trap that discharges the sewage from the sink and is provided on the bottom wall of the sink 3.

Reference numeral 6 denotes a drain branch pipe which is connected to the drain trap 5 for joining and discharging the drain water from the sink 3 and the drain water from the equipment 4, and 7 is connected to a lower end of the branch pipe 6 to connect to a house. A bellows hose that is fitted and connected in the drainage pipe 8 under the floor, and 9 is a drainage hose that draws out the drainage discharged from the device 4, and is connected to the branch pipe 6 by a drainage bag nut 10 provided at the end of the hose. It

FIG. 2 shows the details of the drain branch pipe, 11 is a storage basket installed in the drain trap 5 for collecting the residual food in the drain discharged from the sink 3, and 12 is a JIS standard. A first cylindrical portion having an outer diameter equivalent to that of a hard vinyl chloride pipe and fitted into the drain trap 5 of the sink 3 described above.
The length of the tubular portion 12 is formed to be equal to or larger than the fitting adhesive dimension of a commercially available hard vinyl chloride pipe joint.

Reference numeral 13 is a water seal packing which is fitted and attached to the outer diameter of the first cylindrical portion 12 and seals the drain trap and the branch pipe 6 with water, and 14 is fitted into the first cylindrical portion 12 and is water sealed. Packing 13
It is a cap nut that is attached to the drain trap 5 via.

Reference numeral 15 denotes a second tubular portion having an outer diameter equivalent to that of the first tubular portion and connected to the first tubular portion. The length of the second tubular portion 15 is the same as that described above. A bellows hose connecting portion 16 is formed on the end of the pipe joint so that the bellows hose 7 has a diameter smaller than that of the second tubular portion 15, and the bellows hose 7 is fitted and adhesively connected.
