Also, the term "and/or" as used in this specification includes any and all combinations of the associated listed items.
As to the background technology, the cleaning method of the fan assembly in the prior art has the problem of weaker cleaning capability, and researches show that most of the frequency conversion range hood devices of the range hoods or integrated ranges on the market have no cleaning function, the cleaning function is simpler hot cleaning or steam cleaning, and the fan assembly only adopts a fixed wind speed to clean the fan assembly when hot cleaning or steam cleaning is performed, 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 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 smoke ventilator installed on the fan assembly, wherein the smoke ventilator can be a smoke ventilator device on an integrated kitchen range, an independent smoke ventilator and the like. As shown in fig. 1, the cleaning method of the fan assembly includes steps S102 to S106.
S102, responding to the cleaning instruction, and acquiring the oil stain parameters.
Specifically, the cleaning instruction is an instruction for instructing to start cleaning the fan assembly, and the oil stain parameter is a parameter reflecting the total amount of oil stains attached to the fan assembly. The purge instruction may be issued for a user to trigger a purge button on the kitchen device. If the fan assembly is wanted to be cleaned automatically at fixed time, the fan assembly can also be automatically sent out by a controller of kitchen equipment or the fan assembly after a certain time interval. If the oil stains are required to be automatically cleaned when the oil stains are more, the oil stain parameters can be monitored in real time for a controller of kitchen equipment or a fan assembly, and the oil stains are sent out after the oil stain parameters are more than a trigger threshold. The oil stain parameter may be the weight, thickness, etc. of the oil stain.
S104, determining a target cleaning mode from a plurality of cleaning modes according to the oil stain parameters.
The cleaning mode includes cleaning parameters including heating power and rotational speed. 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 cope with greasy dirt of different degrees and exert the adjustable characteristic of wind speed of the variable frequency fan, the rotating speeds in all cleaning modes are set to be different. The plurality of cleaning modes are that the heating device is used for heating the fan assembly, then the greasy dirt attached to the fan assembly is melted gradually at high temperature, the greasy dirt on the wind wheel is thrown to the volute of the fan assembly in cooperation with the rotation of the fan assembly, and finally the melted greasy dirt, the thrown greasy dirt and the like on the volute flow into the oil cup along the volute. The cleaning parameters of each cleaning mode can be adjusted according to the 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 can be performed without excessive energy consumption, and the condition that the oil stain cannot be removed due to the too low cleaning capacity can be 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 the greasy dirt. The control of the rotation 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 the PWM signal driving the heating device. Since the current researches on the rotation speed control of the fan assembly and the power control of the heating device are mature, similar effects can be achieved by other modes, and the method is not limited herein. After step S106, the oil stain parameter will dynamically change along with the rotation of the fan and the heating of the heating device, the oil stain parameter may be a continuous signal, and the controller of the fan assembly determines the change condition of the oil stain parameter by means of real-time acquisition. The greasy dirt parameter can also be a discrete value which is obtained by the fan component again when the greasy dirt parameter is required to be judged again.
Based on the cleaning method of the fan assembly in the embodiment, 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, and the fan assembly is heated by the heating device under the target cleaning mode to melt the oil stain and run to throw the oil stain down, so that the fan assembly is cleaned. The cleaning method of the fan assembly plays a frequency conversion function of the fan assembly, different fan rotating speeds can be set for different oil pollution conditions, a cleaning mode with proper cleaning capacity is selected, excessive 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.
S202, responding to a cleaning instruction, and acquiring oil stain parameters.
Step S202 is the same as step S102, and reference is made to the above.
S204, determining a target oil stain parameter range in which the oil stain parameter is located from the plurality of oil stain parameter ranges.
It can be understood that the oil stain parameters are divided into a plurality of oil stain parameter ranges according to the oil stain condition of the fan assembly, and the oil stain parameter range where the currently acquired oil stain parameters are located is selected as the target oil stain parameter range.
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 ranges and the cleaning modes, and after determining the target oil stain parameter ranges, 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 reference is made to the above.
In one embodiment, the cleaning parameters further comprise a first preset time period. The first preset time length of each cleaning mode can be set to be the same or different according to actual needs, for example, a certain cleaning mode has a good cleaning effect in experiments, and the first preset time length of the mode can be prolonged when cleaning is required to be performed for a long time according to a group of rotating speeds corresponding to a certain specific cleaning mode. As shown in fig. 3, the step of controlling the operation of the fan assembly according to the rotation speed corresponding to the target cleaning mode includes step S302 and step S304.
S302, controlling the operation of the fan assembly according to the rotating speed corresponding to the target cleaning mode.
Step S302 may refer to the explanation 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 is larger than the preset reduction amount in a first preset time period corresponding to the target cleaning mode. It can be understood that the failure of the oil stain parameter to meet the first condition 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 air blower, so that the cleaning effect meeting the requirement cannot be achieved, and the rotating speed of the air blower assembly needs to be increased to improve the cleaning capability.
In one embodiment, the rotational speed corresponding to the washing mode includes a plurality of gear different rotational speeds. It can be appreciated that there are many ways to increase the rotation speed in step S304, and in this embodiment, a plurality of gear speeds are configured for each cleaning mode, and the rotation speed can be increased by up-adjusting the gear speed. 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 cleaning 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 modes.
S404, judging whether the oil stain parameter meets the first condition.
The oil stain parameter at this time is the re-acquired oil stain parameter or the real-time value of the oil stain parameter. If the oil stain parameter does not satisfy the first condition, the process proceeds to step S406. And if the oil stain parameter meets the first condition, maintaining the rotation speed gear unchanged.
S406, the rotating speed corresponding to the target cleaning mode is up-shifted by one gear.
Specifically, the fan assembly starts to operate from the lowest gear rotating speed in the rotating speeds corresponding to the target cleaning modes, and whether the oil stain parameters meet the first condition in the process that the fan assembly operates at the lowest gear rotating speed is judged. If the rotation speed is satisfied, the cleaning effect is good, and the rotation speed is not required to be adjusted. If the oil stain parameter does not meet the first condition, the gear of the fan assembly is adjusted up by one gear from the lowest gear, and whether the oil stain parameter meets the first condition is continuously judged after the gear is lifted. If the rotation speed is satisfied, the cleaning effect is good, and the rotation speed is not required to be adjusted. If not, the gear of the fan assembly is continuously lifted.
In one embodiment, the cleaning parameters further comprise a second preset time period. The second preset time length of each cleaning mode can be set to be the same or different according to actual needs, for example, a certain cleaning mode has a good cleaning effect in experiments, and the second preset time length of the mode can be prolonged when cleaning for a long time according to the highest gear rotating speed of a certain specific cleaning mode is needed. The cleaning modes comprise N cleaning modes M 1,M2...MN, and the heating power and the rotating speed corresponding to the cleaning mode M i-1 are smaller than those corresponding to the next cleaning mode M i of the cleaning mode M i-1, and i is more than or equal to 2 and less than or equal to N. In addition to the gradual increase in rotational speed between the cleaning modes, the heating power is also gradually increased, enhancing the cleaning ability from two factors of the cleaning parameters together. As shown in fig. 5, the cleaning method of the fan assembly further includes steps S502 to S510 after determining the target cleaning mode from the plurality of cleaning modes according to the oil stain parameters.
S502, controlling the fan assembly to operate according to the lowest gear rotating speed in the rotating speeds corresponding to the target cleaning modes, and controlling the heating device to heat according to the heating power corresponding to the target cleaning modes.
S504, judging whether the oil stain parameter meets the first condition.
The oil stain parameter at this time is the re-acquired oil stain parameter or the real-time value of the oil stain parameter. If the oil contamination parameter does not satisfy the first condition, the process proceeds to step S506. And if the oil stain parameter meets the first condition, maintaining the rotation speed gear 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 cleaning mode is not the highest gear rotation speed, the step S508 is shifted, and if the rotation speed corresponding to the target cleaning mode is the highest gear rotation speed, the step S510 is shifted. It can be appreciated that the purpose of improving the cleaning ability can be achieved by continuing to up-regulate the rotational speed when the rotational speed of the fan gear is not up-regulated to the highest gear rotational speed among rotational speeds corresponding to the current target cleaning mode. And when the gear rotating speed of the fan is up-regulated to the highest gear rotating speed in the rotating speeds corresponding to the current target cleaning mode, the step S510 is carried out.
And S508, the rotating speed corresponding to the target cleaning mode is up-shifted by one step, and the step of judging whether the oil stain parameter meets the first condition is returned to be continuously executed until the oil stain parameter meets 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 up-regulated to the highest gear rotating speed, the greasy dirt parameter does not meet the second condition, and the target cleaning mode is not the cleaning mode M N, and then the target cleaning mode is switched to be the next cleaning mode.
The second condition includes that the oil stain parameter is larger than the first threshold value within a second preset time period corresponding to the target cleaning mode. The first threshold may be a clean threshold of the blower assembly. Specifically, after the fan assembly runs for a second preset period at the highest gear rotational speed in the rotational speeds corresponding to the target cleaning modes, if the oil stain parameter is still greater than the first threshold, it means that the cleaning capability of the current target cleaning mode is insufficient to remove most oil stains, and further improvement of the cleaning capability is required. After the switching of the target cleaning mode is completed, execution is restarted from step S502 in the switched target cleaning mode. When the target cleaning mode is switched to a cleaning mode M N with the maximum heating power and rotation speed in the cleaning mode, the cleaning mode M N is started to try cleaning at the lowest gear rotation speed and whether the oil stain parameter meets the first condition is judged, if the oil stain parameter does not meet the second condition after being lifted to the highest gear rotation speed of the cleaning mode M N, a prompt signal can be sent to inform a user that the oil stain is difficult to clean, and the cleaning mode M N can be repeatedly used for attempting cleaning.
In one embodiment, the cleaning mode is divided into a simple cleaning mode, a general cleaning mode, and a difficult cleaning mode. The simple cleaning mode corresponds to the first oil stain parameter range, the general cleaning mode corresponds to the second oil stain parameter range, and the difficult cleaning mode corresponds to the 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 the 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 corresponding rotating speed of the simple cleaning mode is two gears, one gear is a rotating speed value between 600 and 800r/min, the other gear is 900r/min, and the corresponding heating power of the simple cleaning mode is the power for maintaining the temperature of the fan assembly at 80 ℃. The corresponding rotating speed of the general cleaning mode is two gears, one gear is a rotating speed value between 800 and 1000r/min, the other gear is 1100r/min, and the corresponding heating power of the general single cleaning mode is the power for maintaining the temperature of the fan assembly at 120 ℃. The corresponding rotating speed of the difficult cleaning mode is two gears, one gear is a rotating speed value between 1200 r/min and 1500r/min, the other gear is 1600r/min, and the heating power corresponding to the general single cleaning mode is the power for maintaining the temperature of the fan assembly at 150 ℃. The first preset time is the same for each cleaning mode, for example 1 minute. The second preset time is the same for each cleaning mode, for example 10 minutes.
In one embodiment, the cleaning parameters further comprise a second preset time period. As shown in fig. 6, the cleaning method of the fan assembly further includes: if the target cleaning mode is the rotation speed and the heating power corresponding to each cleaning mode are highest, the fan assembly is controlled to operate according to the rotation speed corresponding to the target cleaning mode, and the greasy dirt 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 rotation 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 is repeated until the greasy dirt parameter meets the second condition or the repeated execution times reach the preset times. The second condition includes 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, when the target cleaning mode is the corresponding rotation speed and heating power in each cleaning mode are highest, the current target cleaning mode is the strongest cleaning mode, if the blower assembly is tried to be cleaned in the strongest cleaning mode and the greasy dirt parameter still cannot meet the second condition, the blower assembly is repeatedly tried to be cleaned in the target cleaning mode until the greasy dirt parameter meets the second condition or the repeated times reach the preset times in the cleaning process, and then cleaning is stopped. If the oil stain parameter still does not meet the second condition after the repeated times reach the preset times, a prompt signal can be sent out to inform a user that the oil stain is difficult to clean.
In one embodiment, the step of controlling the heating device and blower assembly to perform the grease cleaning according to the target cleaning mode includes: and controlling the heating device to heat for a third preset time period with the heating power corresponding to the target cleaning mode, and controlling the fan assembly to work at the rotating speed corresponding to the target cleaning mode. It can be understood that, because the adhesion capability of the oil stain is stronger, the oil stain is difficult to be thrown off directly only by the operation of the fan assembly, so that the heating device can be heated for a third preset time in advance, and the oil stain begins to melt and then begins to be thrown off while being heated. In one specific embodiment, the third preset time period is 3 minutes.
In one embodiment, as shown in fig. 6, the step of acquiring the oil stain parameter includes S602 and S604.
S602, acquiring the current weight of the fan assembly.
It will be appreciated that the amount of oil attached to the fan assembly may be determined by the current weight of the fan assembly, as the oil may cause the weight of the fan assembly to increase after being attached to the fan assembly. 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 should be 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.
S604, obtaining the oil stain weight as the oil stain parameter according to the difference between the weight of the fan assembly and the weight of the clean fan assembly.
It can be understood that the oil stain weight can be obtained by subtracting the clean fan assembly weight from the obtained fan assembly weight, so as to determine the oil stain parameters. Because the weight of the greasy dirt is small compared with that of the clean fan assembly, a weight detection unit with higher detection precision, such as a weight detection unit with resolution of 1 gram or less, should be adopted.
In one embodiment, the step of obtaining the oil stain parameter may also include the steps of: acquiring the oil stain thickness of the fan assembly; and obtaining oil stain parameters according to the oil stain thickness of the fan assembly. It can be appreciated that the thickness of the oil stain can also well reflect the oil stain condition of the fan assembly. The thickness of the oil dirt 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 steps in the flowcharts of fig. 1-6 are shown in order as indicated by the arrows, these steps are not necessarily performed in order as indicated by the arrows. The steps are not strictly limited to the order of execution unless explicitly recited herein, and the steps may be executed in other orders. Moreover, at least a portion of the steps of fig. 1-6 may include multiple steps or stages that are not necessarily performed at the same time, but may be performed at different times, nor does the order in which the steps or stages are performed necessarily occur sequentially, but may be performed alternately or alternately with other steps or at least a portion of the steps or stages in other steps.
