1. A multifunction dispensing apparatus, comprising:
a head assembly including a dispenser head, a first port, and a second port;
a tank to which the head assembly is secured; and
a replaceable chemical cartridge installed within the tank, the replaceable chemical cartridge being filled with a soluble chemical product, the replaceable chemical cartridge includes a cartridge inlet port to which the first port of the head assembly is connected, cartridge space defined as a region between an internal upper surface of the replaceable chemical cartridge and a top of the soluble chemical product, and a series of cartridge outlet ports positioned down along a longitudinal axis of the replaceable chemical cartridge in a manner regulating cartridge flow and producing a gradual dissolution of the soluble chemical product, the series of cartridge outlet ports being connected to the second port for permitting the outlet flow from the dispensing apparatus;
wherein cartridge flow, that is, flow of bypass water that is diverted into and through the replaceable chemical cartridge, enters via the first port, passing through an inlet channel of the first port, then into the cartridge inlet port, the cartridge flow then enters the cartridge space, the cartridge flow causing gradual dissolution of the soluble chemical product, forming a semi-saturated cartridge flow, which carries chemical product out the replaceable chemical cartridge through the series of cartridge outlet ports, after the semi-saturated cartridge flow exits the cartridge outlet ports, the flow continues up through an annulus space between the replaceable chemical cartridge and an outlet channel of the second port, then into an outlet space in the region of the second port.
