(2) acquisition processing module is analyzed the monitored data of noise transducer transmission, and itself and default sound qualitative data limit value are compared, if monitor value lower than limit value, continues default laundry flow process, laundry finishes, if monitor value is not less than limit value, triggers and start adjusting module;
(3) adjusting module carries out reduction of speed or adjusts eccentric processing washing machine, returns to step (2).
The noise monitoring method of the described pulsator washing machine with noise transducer, in described step (2), also comprise that the number of times that monitor value is not less than to limit value carries out stored count, and judge whether count value is less than predetermined threshold value, if, trigger and start adjusting module, if not, enter low speed dewatering state until laundry finishes.
The noise monitoring method of the described pulsator washing machine with noise transducer, described predetermined threshold value is 3 times.
As shown from the above technical solution, the present invention is by installing noise transducer additional, in conjunction with the acquisition processing module and the adjusting module that are integrated on computer board, vibration noise situation to pulsator washing machine is carried out real-time continuous monitoring, and taking sound qualitative data as reference, if monitor value reaches default limit value under certain conditions, washing machine is carried out reduction of speed or adjusts eccentric processing, whole laundry flow process can steadily be completed " peace and quiet ".The present invention can improve complete machine in the performance aspect noise, vibration, safety, life-span, at utmost improves user satisfaction.
Brief description of the drawings
Fig. 1 is structural representation of the present invention (upward view);
Fig. 2 is the A-A profile of Fig. 1;
Fig. 3 is method flow diagram of the present invention.
Detailed description of the invention
Further illustrate the present invention below in conjunction with the drawings and specific embodiments.
As shown in Figure 1 and Figure 2, a kind of pulsator washing machine with noise transducer, comprise casing 1 and be arranged on transmission system and the computer board in casing 1, noise transducer 5 is fixed on the bottom at casing 1 right back angle by support, near driveline arrangement, on computer board, be integrated with acquisition processing module and adjusting module.
Under washing machine running state, transmission system drives impeller or inner core 4 rotate, and except transmission system itself is sent noise, the urceolus 3 that inner core 4, suspension rod 2 mount and base 7 all may vibrate and send noise under live load effect.Noise transducer 5 carries out Real-Time Monitoring to these noises, and monitored data is transferred to acquisition processing module by connection 6.Acquisition processing module is analyzed these monitored data that collect, and (noise based on different spectral is different on the impact of user's impression from default sound qualitative data limit value, in conjunction with frequency spectrum and decibel value, noise qualities is considered and is limited) compare, in the time that Real-Time Monitoring value reaches default sound qualitative data limit value, trigger and start adjusting module.Adjusting module carries out reduction of speed to washing machine or adjusts eccentric processing, to ensure not occur allowing user be difficult to the noise of accepting in whole laundry cycles.
As shown in Figure 3, a kind of noise monitoring method of the pulsator washing machine with noise transducer, comprises the following steps:
(1) noise transducer carries out Real-Time Monitoring to the vibration noise producing in washing machine running, and monitored data is transferred to acquisition processing module;
(2) acquisition processing module is analyzed the monitored data of noise transducer transmission, and itself and default sound qualitative data limit value are compared, and judges that whether monitor value is lower than limit value, if, continue default laundry flow process until laundry finishes, if not, execution step (3);
(3) number of times that monitor value is not less than to limit value carries out stored count, and judges whether count value is less than predetermined threshold value, if so, execution step (4), if not, execution step (5);
(4) trigger and start adjusting module, adjusting module carries out reduction of speed or adjusts eccentric processing washing machine, returns to step (2);
(5) enter low speed dewatering state until laundry finishes.
Starting laundry flow process from user finishes to laundry, due to the intervention of noise transducer 5, the vibration noise producing in washing machine running is carried out to Real-Time Monitoring, when Real-Time Monitoring value is during lower than sound qualitative data limit value, the normal operation of laundry flow process is until finish the now existence of the imperceptible noise transducer 5 of user, in the time that Real-Time Monitoring value reaches sound qualitative data limit value, acquisition processing module triggers and starts adjustment programme, Real-Time Monitoring value is passed judgment on, if Real-Time Monitoring value, lower than sound qualitative data limit value, continues laundry flow process until laundry finishes after adjustment again, excessive for preventing Real-Time Monitoring value, in any case so that adjust, all cannot be lower than the appearance of default this extreme case of sound qualitative data limit value, the number of times that Real-Time Monitoring value is not less than to sound qualitative data limit value carries out stored count, in the time that stored count value reaches predetermined threshold value, no longer trigger and start adjustment programme, but directly enter low speed dewatering state until laundry finishes (above-mentioned extreme case generally only there will be at dewatering state), as predetermined threshold value being made as 3 times, represent that carrying out at most 2 times adjusts, if noise Real-Time Monitoring value is still not less than sound qualitative data limit value, directly enter low speed dewatering state until laundry finishes.Limit adjusting number of times, can prevent above-mentioned extreme case on the one hand, on the other hand, the power saving of also can economizing on water.
The above embodiment is only that the preferred embodiment of the present invention is described; not scope of the present invention is limited; design under the prerequisite of spirit not departing from the present invention; various distortion and improvement that those of ordinary skill in the art make technical scheme of the present invention, all should fall in the definite protection domain of claims of the present invention.
