Abstract
An ultrasonic cleaning apparatus with a cleaning reservoir having a plurality of chambers, which are selectably fillable with cleaning fluid. The chambers of the multi-chamber reservoir are fluidly interconnectable, the apparatus further comprising a fluid distribution pump and a controller for sequentially controlling a fluid flow between the chambers during an ultrasonic cleaning cycle. Such a multi-chamber reservoir has the advantage of reducing the total volume of fluid required to clean vessels in the reservoir, since the cleaning process can be performed in a staged or sequential procedure, and the cleaning and/or rinsing fluid reused in each chamber, allowing the apparatus to be more compact.
Claims14
An ultrasonic cleaning apparatus comprising:
- a cleaning reservoir having a fluid inlet configured to supply cleaning fluid into the cleaning reservoir, and first and second chambers, wherein the first chamber is fluidly interconnectable with the second chamber via a fluid port having a valve;
- at least one ultrasonic generator;
- an air suction pump connected to the second chamber and operable to create a vacuum pressure in the second chamber and thereby generate a pressure differential between the first chamber and the second chamber;
- and
- a controller configured to activate the air suction pump and close and open the valve in the fluid port,
- wherein the cleaning fluid is introduced into the cleaning reservoir via the fluid inlet and transferred from the first chamber into the second chamber through the fluid port with the valve open due to the pressure differential generated by the air suction pump.
