Embodiment Construction

[0015] With reference to the accompanying drawings, figure 1 A perspective view of an upright carpet cleaning machine 60 according to one embodiment of the present invention is depicted. Upright carpet cleaner 60 includes an upright handle assembly 62 rotatably attached to the rear of a floor mating area or floor assembly 64 which is moved and cleaned along a floor 74 such as carpet 74 . Floor assembly 64 includes two rotatably mounted laterally moving wheels 66 (only left wheel 66L shown). A tank or solution tank assembly 76 is removably attached to the handle area 62 of the cleaning machine 60. An air / water separator and recovery tank 80 combination having mounting handle 332 is removably mounted above the motor / fan assembly of base plate assembly 64 and is surrounded by a shroud area 82 . A floor nozzle assembly 124 is removably mounted to the housing section 82 of the floor assembly 64 and is in fluid communication with the recovery tank 80 for the introduction of air an...

Abstract

A cleaning apparatus for cleaning a surface in which cleaning solution is dispensed to the surface is provided. The cleaning apparatus includes a distributor for dispensing solution to the surface and a solution tank fluidly connected to the distributor for supplying a flow of solution to the distributor. The solution tank has a bottom portion and an upper portion. A constant head device is fluidly connected to the solution tank such that the flow of solution from the solution tank to the distributor is substantially constant independent of the level of solution in the solution tank.

Description

technical field [0001] The invention relates to a washing machine with a constant water head device. Background of the invention [0002] Floor cleaning machines are known which have a liquid distribution system for dispersing detergent to clean the floor and / or cleaning water to rinse the floor. Often when cleaning floors, detergent from a tank is automatically mixed with cleaning water, and the mixed cleaning solution is then dispensed onto the floor. It is desirable to maintain a constant mix ratio between detergent and cleaning water, especially in low cost gravity flow systems. However, as the water and detergent levels decrease when using the cleaning solution in a gravity flow system, the flow rates out of the tank also decrease and are not proportional to each other. This is due to the different hydrostatic heads caused by the different liquid levels of the water and detergent in their respective tanks. These variable flow rates produce a variable mix ratio. One ...
