In one example, controlling the food waste disposer to operate or shut down can further include: after the running time of the food waste disposer after starting working exceeds the preset time length set by the time setting chip, when the current value and the voltage value of the motor 6 reach corresponding first set values, controlling the food waste disposer to stop working; and when the running time of the food waste disposer after starting to work does not reach the preset time set by the time setting chip, the electronic centrifugal switch 7 does not act, namely the food waste disposer maintains the corresponding running state. The motor is detected after the motor runs for a preset time through the electronic centrifugal switch, the motor is automatically stopped when no load is determined, the reliability is high, the timeliness is good, the defect of manual control stop in the prior art can be overcome, the use convenience is improved, and the user experience is further improved.
For example: the food waste disposer adopting the control of the electronic centrifugal switch 7 confirms the running state of the motor 6 by synchronously detecting the current value and the voltage value of the motor 6 through the electronic centrifugal switch 7 (when the synchronous values of the current and the voltage are reached, the motor can be considered to reach the no-load rotating speed-food grinding is finished, when the food waste load is not put at the initial starting stage of the motor, the no-load rotating speed can be reached in one stage, in order to distinguish the two states, a program is needed in the electronic centrifugal switch to set the main winding to be disconnected by a controllable relay after a specific time (such as 30S) after the starting of the motor):
⑴ when the motor 6 is started, the relay controls the main and auxiliary windings of the motor 6 to be switched on, and the garbage processor starts to work.
⑵ when the current and voltage reach the set range (for example, the second set value), the secondary winding of the motor can be cut off to increase the rotation speed of the motor when the motor is running normally.
⑶ the food waste disposer will operate for a time (e.g. a preset time duration, preferably 30S) exceeding the time value set by the program of the centrifugal switch chip (e.g. time setting chip), when the current value and the voltage value detected synchronously reach the first set value (e.g. the motor 6 reaches the idle speed 1500r/min), the main winding of the motor 6 will be disconnected, the motor 6 will stop, thereby the food waste disposer will be shut down and stop working, i.e. the idle speed of the motor 6 will be detected by the electronic centrifugal switch 7, the food waste disposer will stop working after the food waste is ground, and the electronic centrifugal switch 7 will not operate when the set time is not reached.
Therefore, the electronic centrifugal switch is applied to the food waste disposer, the functions of increasing the rotating speed of the motor and automatically stopping the motor after grinding are achieved, and compared with the traditional food waste disposer and a mechanical centrifugal switch, the food waste disposer is safer and more convenient for a user to use. By using the electronic centrifugal switch, the problems of poor adjustability, easy generation of mechanical fatigue, short service life, easy generation of sparks and the like of the mechanical centrifugal switch can be solved; the electronic centrifugal switch is completely encapsulated and is not affected by dust, oil stain and water stain; compared with a mechanical centrifugal switch, the electronic centrifugal switch does not need to divide the frequency of the motor, the pole number of the motor and the like, and one switch can be universal.
Since the processing and functions of the control method of the food waste disposer in the present embodiment are basically corresponding to the embodiment, principle and example of the food waste disposer shown in fig. 1, no details are given in the description of the present embodiment, and reference may be made to the related description in the foregoing embodiment, which is not repeated herein.
Through a large number of tests, the technical scheme of the invention is adopted, the electronic centrifugal switch is used for monitoring that the food is automatically stopped after being ground (after a certain time, the motor reaches the no-load rotating speed), so that the manual stop processing, observation and judgment of people can be effectively avoided (the processor is arranged below the water tank, the observation of whether the food is ground or not is inconvenient), and the use is more convenient; on the other hand, the water and electricity can be fully saved, and the waste of water and electricity resources is avoided.
In summary, it is readily understood by those skilled in the art that the advantageous modes described above can be freely combined and superimposed without conflict.
The above description is only an example of the present invention, and is not intended to limit the present invention, and it is obvious to those skilled in the art that various modifications and variations can be made in the present invention. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the scope of the claims of the present invention.
