Abstract
A method and apparatus for dispensing of a product based on weight as a load cell (22) which supports a structure holding the product (20a) to be dispensed. The weight of the product (20a) that is dispensed is determined by use of a controller (23).
Claims21
A dispenser for dispensing an amount of concentrate using a diluent to form a use solution, comprising:
- a) a housing having a cavity, the cavity adapted to receive a concentrate;
- b) the housing having an inlet, whereby diluent enters the cavity and erodes the concentrate to create a use solution;
- c) the housing having an outlet, whereby the use solution exits the cavity;
- d) a product holder positioned to support the concentrate in the cavity of the housing;
- e) a scale;
- f) a support member having a first end and a second end, the first end operatively connected to the scale and a second end operatively connected to the product holder, wherein weight of the concentrate is determined.
A dispensing system for dispensing an amount of concentrate using a diluent to form a use solution, comprising:
- a) a container for holding a concentrate, the container having an opening;
- b) a housing having a cavity, the cavity adapted to receive the container;
- c) the housing having an inlet and an outlet;
- d) a nozzle positioned proximate the inlet;
- e) an inlet conduit operatively connected to the nozzle, whereby diluent is sprayed on the concentrate, through the opening in the container, eroding the concentrate and forming a use solution;
- f) a product holder positioned in the cavity of the housing;
- g) a scale;
- h) a support member having a first end and a second end, the first end operatively connected to the scale and a second end operatively connected to the product holder, wherein weight of the concentrate is determined;
- and
- i) an outlet conduit operatively connected to the outlet of the housing, wherein the use solution exits the cavity of the housing.
A dispenser for dispensing an amount of concentrate using a diluent to form a use solution, comprising:
- a housing having a cavity adapted to receive the concentrate;
- an inlet conduit in the housing that provides the diluent to the concentrate to erode the concentrate and form a use solution;
- the housing having an outlet, whereby the use solution exits the cavity;
- a product holder positioned to support the concentrate in the cavity of the housing;
- a scale that weighs the concentrate as the concentrate is eroded by the diluent;
- and
- a controller that determines when the amount of concentrate has been dispensed in the use solution by the diluent, based upon the weight of the concentrate.
A dispenser for dispensing an amount of concentrate to form a dilute solution, comprising:
- a) a housing having a cavity, the cavity adapted to receive a concentrate;
- b) the housing having an outlet, whereby concentrate that has been eroded exits the cavity;
- c) a product holder positioned to support the concentrate in the cavity of the housing;
- d) a scale;
- and
- e) a support member having a first end and a second end, the first end operatively connected to the scale and a second end operatively connected to the product holder, wherein weight of the concentrate is determined.
