Just as background art, the cleaning method of the fan assembly in the prior art has the problem of weak cleaning capability, and researches show that most of the frequency conversion range hood devices of the range hoods or integrated cookers on the market do not have the cleaning function, the frequency conversion range hood devices with the cleaning function are relatively simple hot cleaning or steam cleaning, the fan assembly only adopts fixed wind speed to clean the fan assembly when the hot cleaning or the steam cleaning is carried out, and the powerful function of the up-conversion fan is not utilized, so that the cleaning method of the fan assembly is difficult to adaptively adjust the wind speed to improve the cleaning capability.
On the one hand, the embodiment of the invention provides a cleaning method of a fan assembly, which can be applied to a controller of the fan assembly and a controller of a range hood installed on the fan assembly, wherein the range hood can be a range hood device on an integrated cooker or an independent range hood and the like. As shown in fig. 1, the cleaning method of the fan assembly includes steps S102 to S106.
And S102, responding to the cleaning instruction, and acquiring oil stain parameters.
Specifically, the cleaning instruction is an instruction for instructing the start of cleaning the fan assembly, and the oil contamination parameter is a parameter for reflecting the total amount of oil contamination attached to the fan assembly. The wash instruction may be issued by a user activating a wash button on the kitchen appliance. If the fan assembly is cleaned automatically at regular time, the cleaning liquid can be automatically sent out by a controller of the kitchen equipment or the fan assembly after a certain time interval. If the oil stain is required to be automatically cleaned when the oil stain is more, the oil stain parameter can be monitored in real time for a controller of kitchen equipment or a fan assembly, and the oil stain parameter is sent out after the oil stain parameter is larger than a trigger threshold value. The oil stain parameters can be the weight, thickness, etc. of the oil stain.
And S104, determining a target cleaning mode from the plurality of cleaning modes according to the oil stain parameters.
The cleaning mode includes cleaning parameters including heating power and rotation speed. The heating power refers to the power of a heating device arranged on the fan assembly, and the rotating speed refers to the rotating speed of the fan assembly. In order to deal with oil stains with different degrees and exert the characteristic of adjustable wind speed of the variable frequency fan, the rotating speeds in all cleaning modes are set to be different. The cleaning modes are all that after the fan assembly is heated by the heating device, oil stains attached to the fan assembly are gradually melted at high temperature, the oil stains on the wind wheel are thrown to a volute of the fan assembly in cooperation with the rotation of the fan assembly, and finally the melted oil stains, the thrown oil stains and the like on the volute flow into an oil cup along the volute. The cleaning parameters of each cleaning mode can be adjusted according to oil stain parameters, so that the cleaning capacity of the target cleaning mode selected from the plurality of cleaning modes is matched with the oil stain condition of the fan assembly, the cleaning is not carried out with too high energy consumption, and the condition that the oil stain cannot be removed due to too low cleaning capacity is avoided.
And S106, controlling the fan assembly to operate according to the rotating speed corresponding to the target cleaning mode, and controlling the heating device to heat according to the heating power corresponding to the target cleaning mode.
The heating device is used for heating the fan assembly to melt oil stains. The control of the rotating speed of the fan assembly can be realized by adjusting the alternating current of the fan assembly, and the control of the power of the heating device can be realized by changing the duty ratio of a PWM signal for driving the heating device. Because the research on the rotation speed control of the fan assembly and the power control of the heating device is mature at present, other modes can be adopted to realize similar effects, and the method is not limited here. After step S106, the oil contamination parameter will change dynamically with the rotation of the fan and the heating of the heating device, the oil contamination parameter may be a continuous signal, and the controller of the fan assembly determines the change condition of the oil contamination parameter in a real-time acquisition manner. The oil stain parameter can also be a discrete value acquired by the fan assembly when the oil stain parameter needs to be judged again.
According to the cleaning method of the fan assembly in the implementation, a target cleaning mode matched with the oil stain condition of the fan assembly is selected from a plurality of cleaning modes according to the oil stain parameters of the fan assembly, the heating device is used for heating the fan assembly to melt the oil stain and the fan assembly is operated to throw the oil stain off in the target cleaning mode, and the fan assembly is cleaned. The cleaning method of the fan assembly has the advantages that the frequency conversion function of the fan assembly is exerted, different fan rotating speeds can be set for different oil stain conditions, a cleaning mode with proper cleaning capacity is selected, too high energy consumption is avoided, and meanwhile the cleaning effect of the fan assembly and the energy-saving effect of the fan assembly during cleaning are improved.
In one embodiment, as shown in fig. 2, the cleaning method of the fan assembly includes steps S202 to S208.
And S202, responding to the cleaning instruction, and acquiring oil stain parameters.
Step S202 is the same as step S102, and the above can be referred to.
And S204, determining a target oil stain parameter range where the oil stain parameter is located from the oil stain parameter ranges.
The oil contamination parameter is divided into a plurality of oil contamination parameter ranges according to the oil contamination condition of the fan assembly, and the oil contamination parameter range where the oil contamination parameter obtained currently is located is selected as the target oil contamination parameter range.
And S206, taking the cleaning mode corresponding to the target oil stain parameter range as a target cleaning mode.
It can be understood that there is a one-to-one correspondence between the oil stain parameter range and the cleaning mode, and after the target oil stain parameter range is determined, a corresponding cleaning mode can be determined as the target cleaning mode.
And S208, controlling the fan assembly to operate according to the rotating speed corresponding to the target cleaning mode, and controlling the heating device to heat according to the heating power corresponding to the target cleaning mode.
Step S208 is the same as step S106, and the above can be referred to.
In one embodiment, the cleaning parameter further comprises a first preset time period. The first preset time duration in each cleaning mode may be set to be the same or different according to actual needs, for example, a certain cleaning mode has a good cleaning effect in an experiment, and a long time of cleaning is required according to a group of rotation speeds corresponding to a certain specific cleaning mode, so that the first preset time duration in this mode may be lengthened. As shown in fig. 3, the step of controlling the operation of the fan assembly according to the rotation speed corresponding to the target washing mode includes steps S302 and S304.
And S302, controlling the fan assembly to operate according to the rotating speed corresponding to the target cleaning mode.
Step S302 may refer to the description in step S106.
S304, judging whether the oil stain parameters meet the first condition, and if not, increasing the rotating speed.
The first condition includes that the reduction amount of the oil stain parameter in a first preset duration corresponding to the target cleaning mode is greater than a preset reduction amount. It can be understood that the oil stain parameter does not meet the first condition, which means that the reduction speed of the oil stain parameter does not meet the requirement, that is, the current cleaning parameter is used for cleaning, the cleaning effect meeting the requirement cannot be achieved, and the rotating speed of the fan assembly needs to be increased to improve the cleaning capacity.
In one embodiment, the speed corresponding to the washing mode includes a plurality of speeds different from each other. It can be understood that there are many ways to increase the rotation speed in step S304, and the embodiment configures the rotation speeds of multiple gears for each cleaning mode, and the rotation speed can be increased by adjusting the gears up. Specifically, as shown in fig. 4, the step of controlling the operation of the fan assembly according to the rotation speed corresponding to the target washing mode includes steps S402 to S406.
And S402, controlling the fan assembly to operate according to the lowest gear rotating speed in the rotating speeds corresponding to the target cleaning mode.
And S404, judging whether the oil stain parameters meet a first condition.
The oil stain parameter at this time is the oil stain parameter obtained again or a real-time value of the oil stain parameter. And if the oil stain parameter does not meet the first condition, the step S406 is carried out. And if the oil stain parameters meet the first condition, maintaining the gear of the rotating speed unchanged.
And S406, the rotating speed corresponding to the target cleaning mode is shifted up by one.
Specifically, the fan assembly starts to operate from the lowest gear rotating speed in the rotating speeds corresponding to the target cleaning mode, and whether the oil stain parameters meet a first condition in the process that the fan assembly operates at the lowest gear rotating speed is judged. If the cleaning effect is satisfied, the cleaning effect is better, and the rotating speed does not need to be adjusted. If not, then with the gear of fan subassembly by the gear of transferring one in the minimum gear to whether the gear promotes the back and continues to judge the greasy dirt parameter and satisfy first condition. If the cleaning effect is satisfied, the cleaning effect is better, and the rotating speed does not need to be adjusted. And if not, continuously lifting the gear of the fan assembly.
In one embodiment, the cleaning parameter further comprises a second preset time period. The second preset time in each washing mode may be set to be the same or different according to actual needs, for example, a certain washing mode has a better washing effect in an experiment, and a longer washing time needs to be performed according to the highest gear rotation speed of a certain specific washing mode, so that the second preset time in this mode may be lengthened. The cleaning mode comprises N cleaning modes M1，M2...MNCleaning mode Mi-1The corresponding heating power and the rotating speed are both less than the cleaning mode Mi-1Next cleaning mode MiAnd i is more than or equal to 2 and less than or equal to N corresponding to the heating power and the rotating speed. Each one ofIn addition to the gradual increase of the rotating speed between the cleaning modes, the heating power is also gradually increased, and the cleaning capability is enhanced by two factors of the cleaning parameters. As shown in fig. 5, the method for cleaning a fan assembly further includes steps S502 to S510 after determining a target cleaning mode from a plurality of cleaning modes according to the oil contamination parameter.
And S502, controlling the fan assembly to operate according to the lowest gear rotating speed in the rotating speeds corresponding to the target cleaning mode, and controlling the heating device to heat according to the heating power corresponding to the target cleaning mode.
And S504, judging whether the oil stain parameters meet a first condition.
The oil stain parameter at this time is the oil stain parameter obtained again or a real-time value of the oil stain parameter. And if the oil stain parameter does not meet the first condition, the step S506 is carried out. And if the oil stain parameters meet the first condition, maintaining the gear of the rotating speed unchanged.
S506, judging whether the rotating speed of the fan assembly is the highest gear rotating speed in the rotating speeds corresponding to the target cleaning mode.
If the rotation speed corresponding to the target washing mode is not the highest gear rotation speed, the process proceeds to step S508, and if the rotation speed corresponding to the target washing mode is the highest gear rotation speed, the process proceeds to step S510. It can be understood that when the gear rotating speed of the fan is not adjusted to the highest gear rotating speed in the rotating speeds corresponding to the current target cleaning mode, the purpose of improving the cleaning capacity can be achieved by continuously adjusting the rotating speed. And when the gear rotating speed of the fan is adjusted to the highest gear rotating speed in the rotating speeds corresponding to the current target cleaning mode, the step S510 is executed.
And S508, the rotating speed corresponding to the target cleaning mode is shifted up by one, and the step of judging whether the oil stain parameters meet the first condition is returned to continue to be executed until the oil stain parameters meet the first condition.
Step S508 is similar to step S406, and reference is made to the above.
S510, after the rotating speed corresponding to the target cleaning mode is adjusted to the highest gear rotating speed, the oil stain parameter does not meet a second condition, and the target cleaning mode is not the cleaning mode MNThen the target cleaning mode is switched to the next cleaning mode.
Second conditionThe method comprises the step of enabling the oil stain parameter to be larger than a first threshold value within a second preset time corresponding to a target cleaning mode. The first threshold may be a cleanliness threshold of the fan assembly. Specifically, after the fan assembly runs for a second preset time at the highest gear rotating speed in the rotating speeds corresponding to the target cleaning mode, if the oil stain parameter is still greater than the first threshold value, the cleaning capability of the current target cleaning mode is not enough to remove most of the oil stains, and the cleaning capability needs to be further improved. After the switching of the target washing mode is completed, the execution is resumed from step S502 in the switched target washing mode. Washing mode M with maximum heating power and rotation speed when target washing mode is switched to washing modeNThen, in a cleaning mode MNThe lowest gear rotating speed starts to try to clean and judges whether oil stain parameters meet a first condition or not, and if the oil stain parameters are promoted to a cleaning mode MNAfter the highest gear rotating speed is still the oil stain parameter does not meet the second condition, a prompt signal can be sent to inform a user that the oil stain is difficult to clean, and the cleaning mode M can be repeatedNCleaning is attempted.
In one embodiment, the washing modes are classified into a simple washing mode, a general washing mode, and a difficult washing mode. The simple cleaning mode corresponds to a first oil stain parameter range, the general cleaning mode corresponds to a second oil stain parameter range, and the difficult cleaning mode corresponds to a third oil stain parameter range. The first oil stain parameter range is that the oil stain parameter is larger than a first threshold value and smaller than a second threshold value, wherein the second threshold value is larger than the first threshold value. The second oil stain parameter range is that the oil stain parameter is larger than a second threshold value and smaller than a third threshold value, wherein the third threshold value is larger than the second threshold value. The third oil stain parameter range is that the oil stain parameter is larger than a third threshold value. The rotating speed corresponding to the simple cleaning mode is two gears, one gear is a rotating speed value between 600 plus 800r/min (r/min), the other gear is 900r/min, and the heating power corresponding to the simple cleaning mode is the power for keeping the temperature of the fan assembly at 80 ℃. The corresponding rotation speed of the general cleaning mode is two gears, one gear is a rotation speed value between 800-. The rotation speed corresponding to the difficult cleaning mode is two gears, one gear is a rotation speed value between 1200 and 1500r/min, the other gear is 1600r/min, and the heating power corresponding to the general single cleaning mode is the power for keeping the temperature of the fan assembly at 150 ℃. The first predetermined time is the same for each wash mode, e.g., 1 minute. The second predetermined time is the same for each cleaning mode, for example, 10 minutes.
In one embodiment, the cleaning parameter further comprises a second preset time period. As shown in fig. 6, the method for cleaning the fan assembly further includes: if the target cleaning mode is that the rotating speed and the heating power corresponding to each cleaning mode are the highest, the fan assembly is controlled to operate according to the rotating speed corresponding to the target cleaning mode, the oil stain parameter does not meet the second condition after the step of controlling the heating device to heat according to the heating power corresponding to the target cleaning mode, the step of controlling the fan assembly to operate according to the rotating speed corresponding to the target cleaning mode is repeated, and the step of controlling the heating device to heat according to the heating power corresponding to the target cleaning mode is repeated until the oil stain parameter meets the second condition or the repeated execution times reach the preset times. The second condition comprises that the oil stain parameter is larger than the first threshold value within a second preset time period corresponding to the target cleaning mode. It can be understood that, under the condition that the target cleaning mode is the highest corresponding rotating speed and heating power in each cleaning mode, the current target cleaning mode is the highest cleaning capability in each cleaning mode, if the fan assembly is tried to be cleaned in the cleaning mode with the highest cleaning capability, the oil stain parameter still cannot meet the second condition, the fan assembly is repeatedly tried to be cleaned in the target cleaning mode until the oil stain parameter meets the second condition in the cleaning process or the repeated times reach the preset times, and then the cleaning is stopped. If the oil stain parameters still do not meet the second condition after the repeated times reach the preset times, a prompt signal can be sent to inform a user that the oil stain is difficult to clean.
In one embodiment, the step of controlling the heating device and the fan assembly to perform the oil contamination cleaning according to the target cleaning mode includes: and controlling the heating device to heat for a third preset time at the heating power corresponding to the target cleaning mode, and then controlling the fan assembly to work at the rotating speed corresponding to the target cleaning mode. It can be understood that the oil stain is difficult to directly throw off only by the operation of the fan assembly due to the strong adhesive capacity of the oil stain, so that the heating device can heat for a third preset time in advance, and the oil stain is heated and thrown off after melting. In one embodiment, the third predetermined period of time is 3 minutes.
In one embodiment, as shown in fig. 6, the step of acquiring the oil contamination parameter includes steps S602 and S604.
And S602, acquiring the current weight of the fan assembly.
It can be understood that the greasy dirt can lead to the weight of fan subassembly to rise after adhering to the fan subassembly, consequently can judge the oily dirt volume of adnexed on the fan subassembly through the current weight of fan subassembly. Because the fan assembly is generally fixedly connected to the kitchen equipment, in order to obtain the weight of the fan assembly, the weight detection unit is arranged at the joint of the fan assembly and the kitchen equipment, so that the weight detection unit bears the fan assembly to measure the current weight of the fan assembly.
And S604, obtaining the oil stain weight according to the difference between the weight of the fan assembly and the weight of the clean fan assembly, and taking the oil stain weight as the oil stain parameter.
It can be understood that the oil contamination weight can be obtained by subtracting the weight of the clean fan assembly from the obtained weight of the fan assembly, so as to determine the oil contamination parameter. Because the weight of the oil stain is smaller than that of the clean fan assembly, a weight detection unit with higher detection precision, such as a weight detection unit with the resolution of 1 gram or less than 1 gram, is adopted.
In one embodiment, the step of obtaining the oil stain parameters may also include the steps of: acquiring the oil stain thickness of a fan assembly; and obtaining oil stain parameters according to the oil stain thickness of the fan assembly. It can be understood that the thickness of the oil stain can well reflect the oil stain condition of the fan assembly. The oil stain thickness of the fan assembly may be obtained by a thickness sensor, such as an ultrasonic thickness sensor, a microwave radiation thickness sensor, or the like.
It should be understood that although the various steps in the flowcharts of fig. 1-6 are shown in order as indicated by the arrows, the steps are not necessarily performed in order as indicated by the arrows. The steps are not performed in the exact order shown and described, and may be performed in other orders, unless explicitly stated otherwise. Moreover, at least some of the steps in fig. 1-6 may include multiple steps or multiple stages, which are not necessarily performed at the same time, but may be performed at different times, which are not necessarily performed in sequence, but may be performed in turn or alternately with other steps or at least some of the other steps.
