Abstract

PURPOSE:To simplify the assembling work, by arranging openings of delivery side water channel and delivery pipe while adjoining each other on the upper face of an auxiliary tank and arranging a flow switch across both openings thereby enabling integral formation of the auxiliary tank from synthetic resin. CONSTITUTION:An opening at a recess 40 for containing a check valve 25 disposed in a suction side water channel 19, an opening 41 of a delivery side water channel 21 and an opening 42 of a delivery pipe 9 are formed while adjoining on the upper face 39 of an auxiliary tank 17. A fixing block 37 integrally formed with a fixing section 32 of an inspection cap 30 for the check valve 25 and a case 33 for containing a flow switch 26 is fixed through a seal packing to the upper face 39 of the auxiliary tank 17. With such arrangement, the openings 41, 42 are formed in same face through punching in approximately same direction, thereby the auxiliary tank 17 can be formed integrally from synthetic resin.

(E) Effect According to Takaaki Honmoto, since the opening of the discharge side waterway and the opening of the discharge pipe are formed on the same surface (upper surface), the molding direction is also approximately the same, so that the molding can be easily performed. It is removed. In addition, the connecting waterway from the opening of the discharge side waterway to the opening of the discharge pipe is bent 180 degrees and sealed, but this connecting waterway is defined by a flow rate switch that is separate from the auxiliary tank. This will not interfere with the work of cutting out the mold for this auxiliary tank.
