Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer and more complete, the technical solutions in the embodiments of the present invention will be described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention, and based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the scope of the present invention.
Firstly, taking the integral framework of the variable-frequency range hood in the prior art as an example, the problem that the display module cannot be powered down for a long time due to the fact that a filter capacitor of a switching power supply is large and the residual electric quantity in a circuit is large when the switching power supply is suddenly cut off in a standby state of the variable-frequency range hood in the prior art is solved. According to the optimization scheme, when the switching power supply is detected to be cut off, whether the variable-frequency range hood is in a standby state or not can be judged at the same time, if yes, the residual electric quantity in the circuit is quickly consumed by driving the heavy-load push rod motor, and therefore the purpose of quickly powering off the variable-frequency range hood is achieved.
Fig. 1 is a schematic view of an overall frame of a prior art medium frequency range hood. The variable frequency range hood comprises an electronic controller module 10 and a control panel module 20. The electronic controller module 10 includes an ac input terminal 101, a filter circuit 102, a rectifier circuit 103, a switching power supply 104, a hot ground side dc output terminal 105, a drive control module 106, a fan intelligent power module 107, an optical coupling isolation communication module 108, a cold ground side dc output terminal 109, a main control module 110, and a motor drive module 111. The electronic controller module 20 includes a display control module 112, a user operated control terminal 113 and a display module 114.
Based on the overall framework schematic diagram of the variable-frequency range hood in the prior art, when the variable-frequency range hood is in a standby state, if the voltage input of the alternating current input end is cut off suddenly, because the filter capacitor capacity of the rectifying circuit is large enough, and the load at the rear end of the electronic controller in the standby state is small enough, the high-voltage direct current at the positive electrode of the capacitor cannot be consumed quickly, and the switching power supply can still normally output electric quantity to the direct current output end at the hot ground side and the direct current output end at the cold ground side. At this moment, main control module, control panel module still are in the on state, therefore, the display module of control panel module still is in the light state, lasts tens of seconds, accomplishes the consumption in order to solve frequency conversion smoke ventilator completion electric quantity when cutting off the power supply suddenly to improve the ability that frequency conversion smoke ventilator reacts fast. The invention aims to ensure that the variable frequency range hood can complete the complete consumption of electric quantity within a set time, thereby improving the reaction capability of the variable frequency range hood and further improving the effect of rationality in the design of the variable frequency range hood.
In order to achieve the above purpose, the present invention provides an electric quantity consumption device and method for an electronic controller. Based on the schematic diagram of the whole frame of the frequency conversion range hood in the prior art shown in fig. 1 and the schematic diagram of the whole frame of the frequency conversion range hood in the invention shown in fig. 2, in terms of hardware, compared with the prior art, the frequency conversion range hood of the invention is additionally provided with an alternating current sampling module, and the alternating current sampling module is connected with a filter circuit and a drive control module respectively.
In the embodiment of the invention, when the variable-frequency range hood is in a standby state and the switching power supply is normally connected, the alternating current sampling signal is an alternating current voltage waveform which has the same frequency as the voltage of the switching power supply but has a smaller amplitude. When the voltage of the alternating current input end is suddenly cut off, the alternating current sampling signal is changed into continuous zero voltage from the alternating current voltage, at the moment, the driving control module transmits a power failure signal to the main control module through the communication circuit of the optical coupling isolation communication module, the main control module rapidly responds to enable the motor driving module to execute the action of motor rotation after receiving the power failure signal, and the electric quantity stored in the filter capacitor is rapidly consumed at the moment of motor starting due to the fact that the motor starting current is large. At this time, the motor does not really act, but the electric quantity stored by the filter capacitor is consumed, so that the driving of the motor at this time can not generate adverse effect on the range hood. Meanwhile, the switch power supply stops working due to insufficient high-voltage direct current voltage input, output voltages of all levels become zero, and the display control module and the display module are immediately powered off.

Meanwhile, the switch power supply stops working due to insufficient high-voltage direct current voltage input, output voltages of all levels become zero, and the display control module and the display module are immediately powered off.
