Detailed Description

The present invention is illustrated by the following examples, but the present invention is not limited to these examples. Modifications to the embodiments of the invention or equivalent substitutions of parts of technical features without departing from the spirit of the invention are intended to be covered by the scope of the claims of the invention.

The first embodiment is as follows:

as shown in fig. 1, the present embodiment provides a control method for an automatic flap structure, after the flap is opened to a proper position, the voltage value of the motor is controlled to make the motor operate continuously according to the low voltage, so that the motor generates continuous and relatively small forward driving force to offset the resilience of the flap, and further effectively avoid the phenomenon of rebounding of the flap.

In this embodiment, the automatic turning plate structure is installed on a kitchen appliance, the kitchen appliance is preferably a steam box, a steam oven, a micro steam box, a micro steam oven or a steaming and baking all-in-one machine, but not limited to the above devices, and other more suitable steam cooking devices can be selected. The steaming and baking integrated machine comprises a turning plate, a shell, a motor and a controller, wherein the turning plate is movably arranged on the shell, preferably, the upper end of the turning plate is hinged with the shell, the output end of the motor is connected with the turning plate to drive the turning plate to rotate around the shell, so that the turning plate is opened or closed, the motor is electrically connected with the controller, the controller comprises an MCU module, a voltage regulation module and a driving module, wherein the MCU module is suitable for outputting a pulse signal to the voltage regulation module, the voltage regulation module is suitable for regulating the voltage into a driving voltage according to the obtained pulse signal, and the regulated driving voltage is output to the driving module to drive the driving module to enable the driving module to drive the motor to operate. In addition, the controller also comprises a timing module for timing.

In this embodiment, the method for controlling the automatic plate turnover structure includes the following steps:

and step S101, the controller receives a working instruction of opening the turning plate.

In this embodiment, the operator starts the steaming and baking all-in-one machine and issues the work order of opening the turning plate, and the controller receives the work order that the operator assigned.

And S102, continuously outputting a pulse signal corresponding to a first preset duty ratio according to a first preset voltage value.

And step S103, adjusting the current voltage to a driving voltage according to the acquired pulse signal, and driving the motor to operate according to the adjusted driving voltage.

In this embodiment, the motor in this embodiment is preferably a direct current motor, and certainly, other more suitable motors may be selected according to actual requirements, the motor in this embodiment is described by taking an example of a steaming and baking all-in-one machine, and the rest of the motor is not described again, in addition, in this embodiment, the first preset voltage value is preferably set to 12V, but not limited to the voltage value, and may also be set to other more suitable voltage values according to actual requirements, and in addition, the first preset duty ratio is preferably set to 100%, but not limited to the value, and may also be set to other more suitable values according to actual requirements. When the controller receives a turning-plate opening signal, the MCU module carries out PWM control on the voltage of the direct current motor so as to continuously output a pulse signal corresponding to a first preset duty ratio according to a first preset voltage value, the voltage adjusting module adjusts the current voltage into a driving voltage according to the acquired pulse signal, and the driving module drives the motor to operate according to the adjusted driving voltage so as to open the turning plate.

And step S104, until the turning plate is locked after being opened in place, adjusting the current duty ratio to adjust the current voltage of the motor to a second preset voltage value.

In the embodiment, the direct current motor is locked up to increase the current of the motor after the turning plate is opened in place, and the controller confirms that the turning plate is opened in place due to the sudden increase of the current of the direct current motor; after the controller receives the signal that the turning plate is opened in place, the MCU module carries out PWM control on the voltage of the direct current motor so as to adjust the current duty ratio to a second preset duty ratio and outputs a pulse signal corresponding to the second preset duty ratio, and therefore the current voltage of the motor is adjusted to a second preset voltage value. In this embodiment, the second preset duty ratio is preferably set to 15%, but not limited to the above value, and may also be set to another more suitable value according to the actual requirement, and in addition, the second preset voltage value is preferably set to 1.8V in this embodiment, but not limited to the above voltage value, and may also be set to another more suitable voltage value according to the actual requirement.

In this embodiment, the voltage regulation module adjusts the current voltage to the driving voltage according to the obtained pulse signal, the driving module drives the motor to keep running according to the adjusted driving voltage so that the motor continuously runs according to the second preset voltage value, namely, after the turning plate is opened in place, the voltage value of the motor is controlled so that the motor continuously runs according to the low voltage, so that the motor generates continuous and relatively small forward driving force to offset the resilience force of the turning plate, and thus, the rebound phenomenon can be eliminated, and meanwhile, the continuous forward driving force can also ensure that the user cannot cause the phenomenon of walking back of the turning plate in the operation process.

And S106, after the motor continuously operates according to the second preset voltage value, counting down according to a preset time value.

Step S107, judging whether a signal for closing the turning plate is received;

if so, driving the motor to reversely rotate so as to directly close the turning plate;

if not, after the countdown is finished, the driving motor reversely rotates to close the turning plate.

In this embodiment, after the turning plate is opened and put in place, the control motor continues to operate according to the low voltage, the controller starts to count down according to the preset time value at this moment, in the counting down process, when it is continuously detected that the user does not close the door within a certain time, the direct current motor is automatically driven to rotate to close the turning plate, thereby preventing the direct current motor from being electrified for a long time to cause heating damage, and simultaneously saving energy.
