Referring to fig. 1, the present application discloses a method for controlling automatic cleaning of a range hood, wherein a first embodiment of the method comprises the following steps:
step 100, starting an automatic cleaning process of the range hood;
step 200, controlling a motor in the range hood to operate in a inching mode for a period of time, wherein the motor is used for driving an impeller to rotate;
step 300, controlling a water pump device in the range hood to start during the inching operation of the motor, and spraying a cleaning solution to the impeller;
and step 400, controlling a motor in the range hood to run at a high speed for a period of time.
The step 100 may be manually controlled to start, or may be automatically started by setting some starting conditions, when the starting conditions are met, for example, in this embodiment, the accumulated service time of the range hood may be used as the starting conditions, when the accumulated service time of the range hood reaches a certain value, the range hood automatically starts the cleaning process, in this embodiment, the oil contamination amount on the impeller may also be used as the starting conditions, and when the oil contamination amount of the range hood is detected to reach a certain value, the range hood automatically starts the cleaning process; after the range hood in this embodiment starts a cleaning process, the motor is first controlled to start and perform inching operation, the inching operation refers to that the motor is powered to operate for a time period t1, then the power operation is cancelled for a time period t2, and then the motor is powered to operate for a time period t1, so that circulation is performed, and meanwhile, during the period that the motor drives the impeller to operate, a water pump device needs to be started to spray cleaning solution onto the impeller, although the power source of the motor is cancelled in the time period t2, the motor can still continue to operate by using inertia, and the embodiment controls the motor to perform inching operation so that the sprayed cleaning solution can be attached to the impeller in a large amount; after the cleaning solution fully dissolves the oil stain on the impeller, the motor is controlled to drive the impeller to rotate at a high speed by the embodiment, so that the waste liquid on the impeller is thrown out, the waste liquid can be effectively prevented from falling onto a cooking range, and after the waste liquid is thrown out, the waste liquid can be collected by using the grease collecting device in the existing range hood, so that the influence on each part in the range hood after the waste liquid is thrown out is avoided.
In this embodiment, the cleaning solution is a liquid capable of dissolving oil stains, and after the cleaning solution is sprayed to the impeller, the oil stains on the impeller are dissolved therein, and finally the impeller is controlled to operate at a high speed to throw the cleaning solution out together with the oil stains.
Further as a preferred implementation manner, in this embodiment, the step 200 includes the following steps:
step 210, setting a first preset time;
step 220, setting the single inching operation time of the motor, and setting the ratio of the power operation time to the non-power operation time in the single inching operation period of the motor;
and step 230, controlling the motor to perform inching operation until the accumulated inching operation time of the motor reaches the first preset time.
In the existing range hood cleaning scheme, the technical scheme that cleaning water is sprayed on the impeller when the motor is controlled to run at a low speed exists, but even if the motor controls the impeller to rotate at the lowest speed, the impeller can generate a large air pressure, so that the cleaning solution is difficult to attach to the impeller. In order to solve the above problem, the present embodiment controls the motor to perform inching operation, during a single inching operation period of the motor, the rotation speed of the motor is gradually increased during a power operation time, and during a non-power operation time, the power of the motor needs to be removed, during which the rotation speed of the motor is gradually decreased. Of course, in order to ensure that the motor does not generate too high wind pressure during operation, the present embodiment needs to control the length of the power operation time, that is, the single inching operation time and the ratio of the power operation time to the non-power operation time during the single inching operation of the motor need to be controlled. In this embodiment, the power operation time in the single jog operation period of the motor is set to 0.5 to 2 seconds, and the non-power operation time in the single jog operation period of the motor is set to 0.5 to 10 seconds.
Further as a preferred implementation manner, in this embodiment, between the step 300 and the step 400, a step a is further included, and in the step a, the motor needs to be controlled to stop running for a period of time. In this embodiment, after the spraying operation of the cleaning solution is completed in the period of the inching operation of the motor, the waste liquid on the impeller does not need to be thrown out immediately, but the cleaning solution needs to be fully dissolved in the oil stain on the impeller, and if the impeller rotates in the process, the dissolving effect of the cleaning solution on the oil stain is easily affected, so that a time period needs to be set between step 300 and step 400 in this embodiment, the impeller is controlled by the motor to stop operating in the time period, and the water pump device also needs to be controlled to stop operating in the time period.
In a further preferred embodiment, the accumulated usage time of the range hood is used as the starting condition in this embodiment. Specifically, in this embodiment, before the step 100, a step B is further included, in the step B, a second preset time is set, the cumulative service time of the range hood is calculated, and when the cumulative service time of the range hood reaches the second preset time, the step 100 is executed. It should be noted that the cumulative service time of the range hood in this embodiment may refer to a cumulative service time of the range hood, or may refer to a cumulative service time of a motor in the range hood, where the cumulative service time of the range hood has different meanings, and the corresponding specific values of the second preset time setting are also different.
Furthermore, in the embodiment, in the step B, when the accumulated using time of the range hood reaches the second preset time, the range hood is in the using state, and the step 100 is executed after the range hood is used this time. Specifically, when the range hood is in a use state, it is detected that the accumulated use time reaches the second preset time, and at this time, in order to not affect the cooking work of the user, the user needs to wait until the cooking work is completed, that is, the step 100 is executed after the range hood is used this time, and the automatic cleaning process of the range hood is started. Whether start range hood self-cleaning process is judged through the operation of user to range hood power button in this embodiment, and when range hood was in the user state promptly, it detected accumulative service time reaches the second preset time, after the user was through pressing range hood's power button, started range hood self-cleaning process, waited that range hood accomplishes the self-cleaning process and self-closing range hood again.
