The specific embodiment
The clear and definite more purpose of the present invention of explanation, characteristic, the advantage of following embodiment with reference to accompanying drawing.
Preferable to the dregs stick preventing device of the dish-washing machine among the present invention and method thereof with reference to the accompanying drawings
Embodiment describes.
With reference to the accompanying drawings 3 and 4 couples of the present invention of accompanying drawing in the dregs stick preventing device of dish-washing machine describe.
At first, as shown in Figure 3, include among the present invention: processor 10c, be installed on the rotating shaft 10d between washing motor 10a and the impeller 10b, and receive the revolving force of above-mentioned washing motor 10a, be used to grind the swill that the inside of above-mentioned circulating pump 10 flows into.
Wherein, when driving above-mentioned washing motor 10a for rotary blade 10b, above-mentioned processor 10c will receive the revolving force of washing motor 10a simultaneously with above-mentioned impeller 10b and be rotated, and the swill that contains in the washings is ground operation.
As shown in Figure 4, the as above dish-washing machine among the present invention of structure, it includes following several sections: circulating pump 10, it is made of washing motor 10a and impeller (Impeller) 10b, and is used to aspirate the washings in the storage tank (Sump); Hall element 20 is used to detect the rotation number (rpm) of above-mentioned washing motor 10a; Systems control division 40, when beginning to carry out washing stroke, above-mentioned washing motor 10a will be rotated with the 1st direction, detect the rotation number (rpm) of washing motor 10a simultaneously by above-mentioned Hall element 20, and in the rotation number increment rate of above-mentioned detected washing motor 10a during less than default definite value, with the direction of rotation of the above-mentioned washing motor 10a of change, and carry out residue with the time that presets and remove stroke.
According to aforesaid structure, when beginning to carry out washing stroke, above-mentioned washing motor 10a will be rotated with corresponding direction according to the control of systems control division 40, simultaneously, above-mentioned Hall element 20 detects the rotation number (rpm of system motor 10a, revolutions per minute, rotation Per minute), and export to said system control part 40.
And, said system control part 40 is in the process of carrying out washing stroke, when the rotation number increment rate (slope) by above-mentioned Hall element 20 detected washing motor 10a during less than default definite value, to be judged as because the operation of the washing motor 10a that the swill stickup causes is obstructed, thereby change the direction of rotation of above-mentioned washing motor 10a, and carry out residue with preheating setting time and remove stroke.
That is, when the operation that is judged as washing motor 10a was obstructed, said system control part 40 will make above-mentioned washing motor 10a carry out contrary rotation or rotation is stirred on a left side/right side.
At this moment, the direction of rotation of above-mentioned washing motor 10a will change, and produce eddy current in washings, thereby the swill of piling up among the washing motor 10a is disperseed, and the processor 10c that upward installs by rotating shaft 10d grinds.
And,,, will show error messages or send buzz by display part 30 when the rotation number by Hall element 20 detected washing motor 10a during still less than default definite value even remove in the process of stroke carrying out above-mentioned residue.
Dregs stick to the dish-washing machine among the present invention prevents that method is described in more detail below.
As shown in Figure 5, at first, when the user imports washing commands (S10 step), will carry out the feedwater operation, preset water level (S20 step) until reaching.
Behind above-mentioned feedwater EO, will make washing motor 10a be rotated (S30 step) with the 1st direction, simultaneously, periodically read rotation number (S40 step) by above-mentioned Hall element 20 detected washing motor 10a.
And, confirm the rotation number increment rate (slope) of above-mentioned washing motor 10a, and judge that whether above-mentioned rotation number increment rate is less than default definite value (S50 step).
The result who judges in above-mentioned steps (S50 step) when the rotation number increment rate of above-mentioned washing motor 10a during greater than default definite value, will carry out washing stroke and operate (S60); The result who judges in above-mentioned steps (S50 step) when the rotation number increment rate of above-mentioned washing motor 10a during less than default definite value, then is judged as above-mentioned washing motor 10a and is in the state of being obstructed (S70 step).
Then,, will carry out residue with preheating setting time and remove stroke, and above-mentioned washing motor 10a will be rotated in the opposite direction or (S80 step) rotated in a left side/right side stirring when above-mentioned washing motor 10a is in when being obstructed state.
Wherein, the direction of rotation of above-mentioned washing motor 10a will change, and produce eddy current in washings, thereby the swill of piling up among the washing motor 10a is disperseed, and the processor 10c that upward installs by rotating shaft 10d grinds.
After above-mentioned residue is removed the stroke end, will make above-mentioned washing motor 10a be rotated (S90 step) with the 1st direction again, and read the rotation number of above-mentioned washing motor 10a simultaneously.
When the current rotation number of above-mentioned washing motor 10a during, will enter into washing stroke operation (S100, S60 step) greater than default definite value.
On the contrary, even remove in the process of stroke carrying out above-mentioned residue,, will show error condition and be prompted to user's (S110 step) when the rotation number of washing motor 10a during still less than default definite value.
Thus, the rotating shaft 10d of the present invention's washing motor 10a is provided with the processor 10c structure that is used to remove swill, and in addition additional have at the residue of the rotation number of washing motor 10a remove stroke, thereby can prevent the phenomenon that washing motor 10a that swill causes is obstructed.
The present invention is not confined to aforesaid embodiment, and in the category that does not exceed basic fundamental thought of the present invention, the operator of relevant industries can carry out various deformation and application to it.
