Though include three rotors in the embodiment described in Fig. 2, yet the present invention and the quantity of restrict rotor never in any form also are 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 container is designed to: can hold the washing agent of some or dosage, for example with liquid or pulverous form.Normally, this container is by lid 7 movably and seal, and can be opened by the YE that is associated, and described YE is controlled by control module, and described control module is used to control 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 usually, 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 of 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 adopts the form of elongate bonding jumper or lead.
Because under the effect of one or more jet rotor, the jet of cleaning solution is periodically aimed at distributor 1, therefore when being in the 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 the container 5 and 6 (specifically referring to Fig. 1) that is used to hold washing agent respectively.
Those electric- conductors 11 and 12 the electric capacity with respect to ground wire are according to the variation of capacity that is contained in the washing agent in cell therefor 5 and 6 and material level and corresponding change.
Be that 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 expediently.
These electric-conductors are connected to and detect and processing circuit unit, hereinafter will describe described circuit arrangement with reference to electric-conductor 10.Be that electric- conductor 11 and 12 can be connected to identical or similar detection and analysis circuit device with being appreciated that.
Consult Fig. 2, distributor 1 comprises detection and processing circuit unit, and this circuit arrangement is marked as 20 as an integral body, and for example, it also can include microprocessor 21.Be expediently, this detection and processing circuit unit directly are installed on the main body of distributor 1, and join with the ECU unit, and the operation of dish-washing machine is controlled in this ECU unit by a jockey 22.Described jockey can be reduced to a single serial link.
This detection and processing circuit unit 20 are connected to ground wire E, and the perhaps neutral conductor of AC supply lines for example connects (directly or by unplanned impedance) lead to earth lead or dish-washing machine.
Device 20 is connected to electric- conductor 10,11 and 12, and is designed to be able to detect respectively the changes in capacitance of each electric-conductor with respect to ground wire E.
In particular, detect and treating apparatus 20 is designed to: can make electric-conductor 10 interrelated with respect to the operation of the changes in capacitance of ground wire and jet rotor.
On the other hand, detection and treating apparatus 20 are designed to: can detect electric- conductor 11 and 12 changes in capacitance with respect to ground wire E, and with a predetermined way, the capacity and the material level of this changes in capacitance and washing agent is interrelated, and wherein washing agent is contained in cell therefor 5 and 6.
Referring to block diagram, be Fig. 3, shown an embodiment exemplaryly, for example detection and treating apparatus 20 comprise excitation level (excitation stage) 30, this excitation level is suitable for high-frequency electrical pumping signal A, B and C, is applied to electric-conductor or electrode 10,11 and 12 respectively; For each described electric-conductor or electrode, also have and obtain level (an acquisition stage) 31, be used for obtaining respectively corresponding LF-response signal a, b and c, those response signals are subjected to the influence with respect to each electric capacity of ground wire of described electric-conductor or electrode.
The response signal of obtaining by level 31 is passed to FIR filter 32, and the output of this filter is connected to the input of forward-backward counter (up-down counter) 33.
