Although include three rotors in the embodiment described in Fig. 2, yet the present invention the never in any form quantity of restrict rotor are also applicable to following situation particularly, the wash chamber of dish-washing machine includes one or two jet rotor.
Distributor 1 includes a supporter 4, for example, can adopt a kind of plastic mo(u)lding.
Consult Fig. 1, supporter 4 includes two independently containers 5 and 6, and described container 5 and 6 illustrates by long dotted line and short dash line.
Container 5 for example can be tubular, and this Vessel Design is: can hold the washing agent of some or dosage, for example, with liquid or pulverous form.Normally, this container is sealed by lid 7 movably, and can be opened by the YE being associated, and described YE is controlled by control module, and described control module is for controlling the operation of dish-washing machine.
Container 6 is designed to: can hold a certain amount of another kind of washing agent, for example washing adjuvant.This washing adjuvant has multiple consumption conventionally, in the process in continuous washing cycle, for multiple consumption is used alternatingly.
For the purpose of simplifying the description, the container 5 and 6 shown in Fig. 1, is parallelepiped shape haply, yet this shape is unfixing, because those containers also can adopt multiple different shape.
Consult Fig. 1 and 2, the supporter 4 of distributor comprises an electric-conductor or electrode 10, for example, adopt the form of elongate bonding jumper or wire.
Due under the effect of one or more jet rotor, the jet of cleaning solution is periodically aimed at distributor 1, and therefore, when in running, the electric capacity with respect to ground wire of electric-conductor 10 is variable.
In a specific embodiment, other electric- conductor 11 and 12 is attached to respectively the container 5 and 6 (specifically referring to Fig. 1) for holding washing agent.
Those electric- conductors 11 and 12 the electric capacity with respect to ground wire, the corresponding change according to being contained in the capacity of the washing agent in cell therefor 5 and 6 and the variation of material level.
Expediently, in the moldings formed therefrom process of the supporter 4 of distributor, electric- conductor 10,11 and 12 also can be by one-body molded.
These electric-conductors are connected to and detect and processing circuit unit, below will describe described circuit arrangement with reference to electric-conductor 10.Understandably, electric- conductor 11 and 12 can be connected to identical or similar determination and analysis circuit arrangement.
