Specific embodiment
In order to make those skilled in the art more fully understand technical solution of the present invention, with reference to the accompanying drawing and by specific
Embodiment to further illustrate the technical scheme of the present invention.
The principle of EDDY CURRENT is to show a coil to be passed through alternating current, and the electric current passed through under certain condition is constant
's.If coil close to measured workpiece, as ship in water, vortex can be induced in workpiece, by vortes interference, coil electricity
Stream can change.Since the size of vortex is with different either with or without defect in workpiece, so the size energy of coil current variation
Reflection has zero defect.It is then the detection realized using the principle of EDDY CURRENT to spray arm revolving speed in the application.
As shown in Figure 1, 2, a kind of dish-washing machine, including liner 1 and setting are provided in the present embodiment in 1 chamber of liner
Interior spray arm 2；Wherein, signal sending and receiving apparatus 3 is additionally provided on liner, at least one end of spray arm 2 is provided with jammer
Structure 4, signal sending and receiving apparatus 3 is for detecting 2 velocity of rotation of spray arm.
Signal sending and receiving apparatus is eddy current detection device 3 in the present embodiment, and interference mechanism 4 is sheet metal.Certainly its
Signal sending and receiving apparatus 3 is photoelectric sensor in his embodiment, and the interference mechanism is reflecting piece.And it is main in the present embodiment
To the machine testing spray arm that washes the dishes by taking signal sending and receiving apparatus is eddy current detection device 3, interference mechanism 4 is sheet metal as an example
2 Rotating speed measrings are illustrated.
In order to reduce controller calculation amount, 2 one end of spray arm is provided with sheet metal in the present embodiment.Certainly, other are implemented
The settable sheet metal in 2 both ends of spray arm in example.And 2 both ends of spray arm are respectively provided with sheet metal then and can make the revolving speed of spray arm 2
Calculate more accurate.Meanwhile signal sending and receiving apparatus 3 meets water generation short circuit in washing process in order to prevent, causes to wash
Bowl machine cannot normally detect the revolving speed of spray arm 2, for this purpose, the side of liner 1 is arranged in signal sending and receiving apparatus 3 in the present embodiment
On wall, it should be noted that signal sending and receiving apparatus 3 is arranged on any side wall of liner 1, which side wall be specifically located at
On be not particularly limited.
To above-mentioned dish-washing machine by taking signal sending and receiving apparatus 3 is eddy current detection device, interference mechanism 4 is sheet metal as an example
It is as follows to detect Rotation Process:
After eddy current detection device 3 is powered, when sheet metal is rotated with spray arm 2, vortex can be induced in sheet metal, by
Vortes interference, the coil current in eddy current detection device can change, and eddy current detection device is recorded according to curent change
The frequency of curent change, and then controller can be made to detect the revolving speed of spray arm 2 according to the curent change in setting time.
A kind of dish washer control method is additionally provided in the present embodiment, as shown in figure 3, the control method is emitted by signal
Reception device 3 detects the rotational frequency of the upper interference mechanism 4 of spray arm 2 to obtain 2 revolving speed of spray arm, according to spray arm 2
Revolving speed adjusts washing parameter.
And the rotational frequency of spray arm 2 is detected to obtain 2 revolving speed of spray arm then above by signal sending and receiving apparatus 3
Specifically include that signal sending and receiving apparatus 3 detects the changed frequency of electric current when spray arm 2 rotates to obtain spray arm 2
Rotational frequency obtains the revolving speed of spray arm 2 according to 2 rotational frequency of spray arm；It should be noted that signal emits in the present embodiment
Reception device 3 is eddy current detection device, and interference mechanism 4 is sheet metal.
Above-mentioned washing parameter can be one of washing water amount, wash time, wash temperature and wash number or a variety of.
Wherein washing water is adjusted according to the velocity of rotation of spray arm 2, and 2 velocity of rotation of spray arm is faster, then it is smaller to wash water,
Velocity of rotation is slower, then it is more to wash water；And wash time is then that 2 velocity of rotation of spray arm is faster, wash time is faster；And
Wash temperature be then whether rotated with spray arm 2 it is related, if spray arm rotate, the heating device work in dish-washing machine is set
Make, if spray arm 2 does not rotate, the heater stop work in dish-washing machine is set, and dish-washing machine alarm equipment alarm is used
To prompt user's spray arm 2 to break down, and then effectively prevent spray arm cisco unity malfunction from causing heating device dry combustion method
Problem occurs.Since the velocity of rotation of spray arm 2 is bigger, the cleaned number of tableware is bigger in the unit time, and entirety is washed
The washing times for washing process needs are then fewer.
As shown in figure 3, the dish washer control method specifically includes:
S1, dish-washing machine energization water flowing, control spray arm rotation；
S2, signal sending and receiving apparatus are powered；
Whether S3, detection signal sending and receiving apparatus occur curent change；
S4, if so, curent change frequency and calculating spray arm revolving speed in record unit time；
S5, washing parameter is adjusted according to spray arm revolving speed；
S6, if it is not, then dish-washing machine cuts off the water supply and alarms.
The dish washer control method provided in the present embodiment, can be according to the received coherent signal of signal sending and receiving apparatus
The frequency for receiving signal is obtained, and then spray arm speed can be obtained according to the signal frequency received.
Note that the above shows and describes the basic principles and main features of the present invention and the advantages of the present invention.The industry
Technical staff it should be appreciated that the present invention is not limited to the embodiments described above, described in above embodiment and specification
