Drawings
Fig. 1 is a flowchart of a method for reminding cleaning of a range hood according to embodiment 1 of the present invention.
Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Example 1
The embodiment 1 of the present invention provides a method for reminding a range hood to clean, wherein a formula P ═ F × V is calculated according to a motor power, where P is the motor power, F is a torque, V is a rotation speed, and a formula P ═ U × I is calculated according to an electric power, where P is the electric power, U is a starting voltage, and I is a starting current, and it can be known that U ═ I ═ F × V, i.e., I ═ F × V/U, and in a normal case, a voltage U ═ 220V, and in a certain time Δ t when a motor is started, at an equivalent rotation speed V, a current I is proportional to a torque F, that is: and I is K F, and K is V/U.
Along with the increase of the service life of the range hood, the oil stain accumulation on the motor rotating shaft and the wind wheel is more, the oil stain attaching effect on the rotating shaft can cause the starting difficulty, the static starting torsion of the motor needs to be larger, and the required current of the motor needs to be larger according to the relation.
Therefore, the starting current of the fan can reflect the oil stain accumulation state of the wind wheel, and therefore the current accumulated time T used by the fan of the range hood is usedaAnd the current starting current I of the fantCan judge when to send out the warning of wasing range hood.
As shown in fig. 1, the method specifically includes the following steps:
step S1: when the range hood is started, the current accumulated time T used by a fan of the range hood is collectedaAnd the current starting current I at the moment of starting the fant；
In the using process of the range hood, the control system controls the current accumulated time T of the fanaAnd accumulating and storing.
Current starting current I of fantThe method comprises the following two modes of collecting, on one hand, measuring and monitoring the starting current of the fan in a mode of directly connecting resistors in series in a load circuit of the wind wheel motor, and on the other hand, measuring and monitoring the starting current of the fan in a mode of indirectly inductively coupling the load circuit of the wind wheel motor.
Determining a preset cleaning reminding current I according to the corresponding relation between the starting current of the fan and the oil stain amount of the wind wheelsAnd a preset cleaning reminding current IsStored in the control systemIn (1).
Step S2: when the current accumulated time TaGreater than preset cleaning reminding time TbFor the current starting current ItAnd a preset cleaning reminding current IsIf the current starting current I is presenttGreater than a preset cleaning reminding current IsAnd controlling the range hood to send out a prompt for cleaning the fan.
If the present starting current ItLess than or equal to preset cleaning reminding current IsThen, the current accumulated time T used by the fan is collected againa', and the current accumulated time T used by the recollection blowera' and prolong the reminding time TcComparing, if the current accumulated time T of the fan use is collected againa' greater than extended reminder time TcControlling the range hood to send out a prompt for cleaning the fan; if the current accumulated time T of the fan use is collected againa' less than or equal to prolonged reminding time TcAnd ending the flow, and judging again when the range hood is restarted next time.
Prolonging reminding time TcAccording to the preset cleaning reminding time TbAnd the present starting current ItAnd a preset cleaning reminding current IsThe proportion relation of (c) is determined.
The method specifically comprises the following steps: the prolonged reminding time TcAccording to the formula Tc＝Tb+Tb*(1－It/Is) Determining, wherein TcIndicating extended reminder time, TbIndicating a preset wash alert time, It/IsRepresenting the ratio of the current starting current to the preset washing-prompting current, ItIndicating the present starting current, IsIndicating a preset wash alert current.
When the current accumulated time TaLess than or equal to preset cleaning reminding time TbAnd then ending the process, and judging again when the range hood is restarted next time.
Because the wind wheel is used for a long time, the starting current of the fan after cleaning at each time and the starting current of the previous fan are changed, so that the preset cleaning reminding current needs to be updated after cleaning at each time for ensuring the accuracy of the next cleaning reminding time.
Specifically, control range hood sends the warning of washing the fan, later still includes:
determining whether the range hood finishes cleaning, if so, collecting the motor starting current after cleaning, and reminding a preset cleaning current IsAnd updating the current to the starting current of the motor after cleaning.
If the cleaning is finished, the current accumulated time T is usedaResetting and collecting the current accumulated time T againa。
Example 2
The embodiment 2 of the invention provides a control system of a range hood, which comprises a collecting unit and a control unit, wherein the collecting unit is used for collecting a smoke signal;
a collection unit for collecting the current accumulated time T used by the fan of the range hood when the range hood is startedaAnd the current starting current I at the moment of starting the fant；
A control unit for counting the current accumulated time TaGreater than preset cleaning reminding time TbFor the current starting current ItAnd a preset cleaning reminding current IsIf the current starting current I is presenttGreater than a preset cleaning reminding current IsAnd controlling the range hood to send out a prompt for cleaning the fan.
A control unit for further controlling the current if the current is startedtLess than or equal to preset cleaning reminding current IsThen, the current accumulated time T used by the fan is collected againa', and the current accumulated time T used by the recollection blowera' and prolong the reminding time TcComparing, if the current accumulated time T of the fan use is collected againa' greater than extended reminder time TcControlling the range hood to send out a prompt for cleaning the fan; if the current accumulated time T of the fan use is collected againa' less than or equal to prolonged reminding time TcAnd ending the flow, and judging again when the range hood is restarted next time.
The control unit is also used for determining whether the range hood finishes cleaning, and then the control unit further comprises: if the cleaning is finished, the current accumulated time T is usedaResetting and collecting the current accumulated time T againa。
The above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention.
