Also, the terminology used in this specification includes any and all combinations of the associated listed items.
In one embodiment, as shown in fig. 1, there is provided a range hood cleaning method, including:
step S110: and monitoring the running state of the range hood.
Specifically, the operating state of the range hood may be analyzed by monitoring the state of the range hood in real time by the controller, for example, monitoring the operating time of a motor of the range hood, the accumulated duration of the operating mode, or the oil contamination level in an inner cavity of the range hood. The controller can adopt an independent control chip or the original control chip of the range hood.
Step S120: and when the running state of the range hood meets a preset first reminding condition, outputting cleaning reminding information.
The specific content of the first reminding condition is not unique, and the first reminding condition is different according to different monitored data. For example, if the controller monitors the accumulated time of the range hood in the operating mode, the first reminding condition may be that the accumulated time of the range hood in the operating mode reaches a certain preset value; if the controller monitors the content of the target gas in the volute of the range hood, the first reminding condition can be that the content of the target gas in the volute is required to reach a certain content value. The specific type of the target gas is not unique, and harmful gas generated by oil stains and the like in the volute can be used as the target gas for content monitoring.
The mode of outputting the cleaning reminding information is not unique, and the controller can output the cleaning reminding information to remind a user by controlling the interactive device of the range hood. In one embodiment, the cleaning alert information is output, including at least one of a light alert, a voice alert, and a cigarette machine alarm alert. Specifically, the interaction device may employ a touch screen, the touch screen includes a display panel, a cleaning key and a reminding unit, and the reminding unit may be a speaker, an indicator light, an alarm, or the like. The reminding unit can be arranged on the touch screen independently, or can be integrated with the cleaning key, for example, when the reminding unit adopts an indicator light, the indicator light can be arranged inside the cleaning key. Correspondingly, the mode of the interaction device outputting the cleaning reminding information can be voice reminding (playing a piece of music), light reminding (flashing, for example, flashing of a cleaning button light), alarm reminding on the cigarette making machine, and the like.
Step S130: and when a cleaning instruction input according to the cleaning reminding information is received, cleaning the range hood.
After receiving the cleaning reminding information, the user can send a cleaning instruction to start a cleaning mode through a cleaning key of the touch screen, and after receiving the cleaning instruction, the controller cleans the range hood. The mode of cleaning the range hood is not unique, and the range hood is cleaned by at least one of ultrasonic cleaning, steam washing and soaking washing. Taking ultrasonic cleaning as an example, the controller can start the ultrasonic generating device, utilize the ultrasonic generating device to directly transmit vibration to the impeller and/or the volute of the range hood, shake off the oil stain and dust adhered on the impeller and/or the volute, do not use any cleaning agent, are more environment-friendly and have low cost.
Step S140: and if the cleaning instruction input according to the cleaning reminding information is not received, outputting the cleaning reminding information and locking the range hood to stop the working mode when the running state of the range hood meets the preset second reminding condition.
Specifically, if the cleaning instruction input by the user is not received within the set time after the cleaning reminding information is output, the user can be considered to fail to start the cleaning mode in time, and the operating state of the range hood is continuously monitored. It can be understood that the second reminding condition is different according to different monitoring data and corresponds to the first reminding condition, and the second reminding condition can be that the accumulated time of the range hood in the working mode reaches another preset value; it may also be desirable to have the content of the target gas in the volute reach another content value. Taking the accumulated time of the range hood in the working mode as an example, if the cleaning instruction is not received, the accumulated use time of the range hood after the cleaning mode is not started is continuously monitored, when a certain preset value is reached, the automatic reminding is started again, the range hood is locked and the working mode is stopped, and if the user does not start the inner cavity for cleaning, the normal working mode of the range hood cannot be started.
According to the range hood cleaning method, the operating state of the range hood is monitored, the cleaning reminding information is output when cleaning reminding is needed to remind a user to start cleaning operation, the problem that the user does not know when cleaning is carried out is solved, the cleaning effect is prevented from being influenced by stubborn grease caused by untimely cleaning, and the use convenience and the intelligence of the range hood are improved.

Specifically, after the operating state of the range hood meets the preset first reminding condition and the cleaning reminding information is output, if the user fails to start the cleaning mode in time, the range hood operates and continues to monitor the operating state next time, and the range hood does not send any reminding.
Step S144: and when the running state of the range hood meets a preset second reminding condition, outputting cleaning reminding information and locking the range hood to stop working.
Similarly, taking the accumulated time length of the range hood in the working mode as an example, the accumulated time length after the cleaning mode is not started is continuously monitored after the range hood is started again, when a second reminding condition is reached (the range hood does not work), the cleaning reminding is sent again, the range hood is locked and stops the working mode, and if the user does not start the inner cavity for cleaning, the normal working mode of the range hood cannot be started.
In this embodiment, if the user still does not in time open clean mode and carry out the inner chamber cleanness and then can cause unable start next time after being reminded, the controller exports clean warning information and the cigarette machine can't be opened when opening the use cigarette machine next time, prevents that the inner chamber from forming stubborn stain and causing clean effect poor.
In another embodiment, as shown in FIG. 3, step S140 includes step S146 and step S148.
Step S146: and if the cleaning instruction input according to the cleaning reminding information is not received, sending out the cleaning reminding information when the range hood is restarted and continuously monitoring the running state of the range hood. Specifically, after the operating state of the range hood meets a preset first reminding condition and cleaning reminding information is output, if a user fails to start a cleaning mode in time, the cleaning reminding information is sent out when the range hood is restarted, and the controller continues to monitor the operating state of the range hood. If the user inputs a cleaning instruction after cooking, the subsequent step of locking the range hood is not performed, and the step S110 can be directly returned.
Step S148: and when the cleaning instruction is not received and the running state of the range hood is continuously monitored to meet the preset second reminding condition, outputting cleaning reminding information and locking the range hood to stop working mode when the range hood is restarted.
Similarly, taking the monitoring of the accumulated time length of the range hood in the working mode as an example, after the start-up reminding is performed in step S146, if the user forgets to input the cleaning instruction again, the operation state of the range hood continues to be monitored together with the last time that no cleaning operation is performed, the range hood continues to monitor the accumulated use time length after the cleaning mode is not started, the range hood does not send out the cleaning reminding information until the second reminding condition is reached, but waits for the range hood to be started again, sends out the cleaning reminding and locks the range hood to stop the working mode, and the normal working mode of the range hood cannot be started if the user does not start the inner cavity cleaning.
In the embodiment, the operation state of the range hood is monitored to meet the preset second reminding condition, the operation state is not automatically started to remind, the range hood is automatically reminded and locked when being started again, the user is ensured to be cleaned before being started again, otherwise the range hood cannot be started, and the user unlocks the range hood to directly enter the working state after starting the cleaning function.
The two embodiments are different in that the first embodiment reminds and locks the cigarette machine as long as the second reminding condition is achieved and the cigarette machine does not work, and can be unlocked only by implementing a cleaning instruction, for example, a cleaning key of the cigarette machine flickers all the time to remind a user, the user can implement cleaning, and the cigarette machine returns to normal operation; the second embodiment is that the restarting after the first reminding condition is reached still gives a reminding opportunity to the user, if not, the monitoring is continued, when the second reminding condition is reached, the cigarette machine does not send out reminding information, but only sends out cleaning information and locks after the restarting, and the cooking can be started only after the cleaning instruction is implemented to unlock the cigarette machine.
In one embodiment, as shown in fig. 4, after step S140, the method may further include step S150: and after the range hood is cleaned according to the received cleaning instruction, unlocking the range hood in a normal working mode.

In addition, most of the existing range hoods with the cleaning function only clean the impeller, but do not have the function of cleaning the oil stains on the inner wall of the volute, and the oil stains adsorbed on the inner wall of the volute also can seriously affect the performance of the range hood. Along with the continuous improvement of people's life, to the increasingly urgent toward of beautiful life, to the continuous rising of the convenience of use demand of intelligent household electrical appliances, to the processing of range hood inner chamber greasy dirt, develop a better effect, the clean mode of more convenient environmental protection has important practical meaning.
Based on this, the range hood that this application provided, fixed connection ultrasonic wave generating device on impeller and/or spiral case, ultrasonic wave generating device includes supersonic generator and ultrasonic transducer, is connected with range hood's controller and carries out program control, utilizes the clean button on the touch-sensitive screen can start ultrasonic wave generating device, and ultrasonic wave generating device directly transmits the vibration to impeller and/or spiral case, shakes the greasy dirt and the dust of adhesion on impeller and/or the spiral case and falls, does not use any sanitizer, and is environmental protection more, and with low costs. When using, reach after the accumulation and predetermine for a long time through monitoring the cigarette machine, remind the user to start ultrasonic cleaning, remove the user from and do not know when this clear puzzlement.
Specifically, as shown in fig. 6, the range hood drives the impeller 4 to rotate by the motor 5 to generate a centrifugal force, so that a negative pressure region is generated inside the volute 6, and due to the pressure difference, the oil smoke outside the casing 3 of the range hood enters the casing 3 through the oil screen 8 and is then discharged to the common flue through the volute 6, the impeller 4 and the check valve 1. Oil smoke flows out of the volute through the volute oil discharge hole due to oil dirt condensed by the volute 6 and the impeller 4, enters the oil cup 9 through the oil receiving disc 7, and directly enters the oil cup 9 through the oil dirt condensed by the oil screen 8. The volute 6 and the impeller 4 are used as core components of the range hood, and if the range hood is not cleaned in time, the performance of the range hood is greatly influenced. Except the performance is reduced, the oil stain is accumulated and bred with bacteria, peculiar smell and other residues, which seriously affect the body health of the user.
As shown in fig. 7, the ultrasonic lumen cleaning process is: the volute 6 is connected and fixed with the ultrasonic device 2, and the ultrasonic device 2 internally comprises an ultrasonic generator and an ultrasonic transducer. A cleaning key is arranged on a control panel of the range hood, a user touches the cleaning key to start an inner cavity cleaning function, the controller 10 controls the ultrasonic generator to output a square wave after the cleaning is started, the square wave is changed into a sine wave after the matching, the ultrasonic transducer transmits the sound wave to a volute-impeller system to be cleaned, the ultrasonic transducer is fixedly arranged on the volute wall (in close contact), at the moment, the volute-impeller-motor system (a fan system) and the ultrasonic transducer form a resonance body, and therefore grease particles adhered to the fan system vibrate at a high speed at a balance position, the grease particles are loosened and separated from the volute and the impeller wall in time, and the cleaning effect is achieved. The ultrasonic device 2 is utilized to directly transmit vibration to the volute 6 and the impeller 4, oil stains and dust adhered to the volute 6 and the impeller 4 are vibrated down, no cleaning agent is needed, and the ultrasonic device is more environment-friendly and low in cost.
As shown in FIG. 8, the user can start the cleaning mode to clean in time by using the cleaning key on the touch panel according to the reminding of the cigarette machine. The control flow specifically comprises the following steps: when the cigarette machine is in normal operating mode, the user starts the cigarette machine, collects cigarette machine normal operating time length T1, and the user starts the cigarette machine for the second time, collects cigarette machine normal operating time length T2, … … the nth time user starts the cigarette machine, collects cigarette machine normal operating time length Tn, when monitoring cigarette machine normal operating and accumulating to T (T ═ T-1+T2+……+TN) When the time value is more than or equal to the first initial set time value Ta, the range hood starts an automatic user cleaning reminding function; when the condition for reminding the user of cleaning the function is met, the cigarette machine is running, and the controller controls the cigarette machine to enter the function for reminding the user of cleaning after the running is finished. The reminding user can be a voice reminding on the cigarette making machine (playing a piece of music), a light reminding on the cigarette making machine (flashing, for example, the cleaning button light flashing), an alarm reminding sent by the cigarette making machine, and the like.
After the cigarette machine implements the function of reminding a user to clean, starting monitoring and accumulating the working time of each time, and if the accumulated time reaches a certain initial preset time value Ta, if the user timely touches a key on the panel to start the cleaning mode, the cigarette machine exits the cleaning mode after the vibration cleaning is finished, enters a normal working standby mode, clears the accumulated time, and continues the monitoring accumulated working time of the next round. If the user fails to open the cleaning mode in time after reminding, when opening the range hood next time, the range hood still can normally operate to continue monitoring and accumulating the length of time of use after not opening the cleaning mode, when reaching a certain preset initial value, the range hood starts the automatic reminding again, if the user does not open the inner chamber cleaning, the normal working mode of the range hood cannot be opened. If the user has started the cleaning mode, then the cigarette machine withdraws from the cleaning mode after the inner chamber is cleaned, unblock cigarette machine mode, get into normal standby mode, the long zero clearing of accumulation to this circulation reminds the user in time to clean the inner chamber, keeps the inner chamber clean for a long time, prevents that the too long grease from forming stubborn stain influence cleaning performance in the inner chamber.
In particular, if the user does notThe reminding function of the range hood is managed, the inner cavity is not opened for cleaning all the time, the working flow of the range hood accumulating the working time all the time is that when the normal work of the range hood is monitored to be accumulated to T/(T/＝T1+T2+……+TN+TN+1+ … …) is more than or equal to the second initial setting duration value Tb, and if not opening clean mode, the user just the cigarette machine can not normal operating, opens clean mode back, cigarette machine normal operating, and the long zero clearing of accumulative duration begins to get back to the monitoring again and collects cigarette machine length of use to this greasy dirt that guarantees the inner chamber forms and does not become stubborn stain, keeps good clean effect, extension cigarette machine life.
The method for cleaning the range hood is not limited to the ultrasonic cleaning method, and can also be any cleaning method such as steam washing, soaking washing and the like. In addition, the concentration of harmful gases can be monitored, or the working state of the range hood can be monitored, specifically, the working time of the motor, namely the using time of the range hood, can be monitored.
