Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.
Referring to fig. 1, a vacuum cleaner 100 according to an embodiment of the present invention is used for cleaning dust and debris from an environment. The vacuum cleaner 100 includes a main housing 20, a control system (not shown), and a dust collection structure 40, wherein the main housing 20 includes an accommodating cavity 21, an air inlet and an air outlet are respectively formed at two opposite ends of the accommodating cavity 21, and the dust collection structure 40 and the control system are both accommodated in the accommodating cavity 21. The dust collection structure 40 can generate negative pressure under the control of the control system, dust and sundries in the external environment enter the accommodating cavity 21 from the air inlet along with the air flow, the dust and the sundries are left in the dust collection structure 40 after being filtered by the dust collection structure 40, and clean air flow returns to the external environment again through the air outlet.
The dust collector 100 further comprises a humidity sensor 60, the humidity sensor 60 is accommodated in the accommodating cavity 21 and is in communication connection with the control system, the humidity sensor 60 is used for detecting the humidity of the airflow accommodating the cavity 21 and sending a detection signal to the control system, and the control system can control the working state of the dust collector 100 according to the detection signal, so that the damage of the dust collection structure 40 caused by the overlarge humidity of the airflow accommodating the cavity 21 is avoided, and the service life of the dust collector 100 is prolonged.
Specifically, the dust suction structure 40 includes a driving assembly 43 and a dust cup assembly 41, the driving assembly 43 is located at one end of the accommodating cavity 21 where an air outlet is formed, and is used for generating negative pressure, and the dust cup assembly 41 is located at one end of the accommodating cavity 21 where an air inlet is formed and is used for separating dust and impurities. Thus, the airflow entering the accommodating cavity 21 from the air inlet enters the dust cup assembly 41 for filtering, and the filtered clean airflow passes through the driving assembly 43 and returns to the external environment through the air outlet. The inventor finds that the driving assembly 43 is easily damaged by water (or other liquid) entering due to the components such as the motor, and the like, so that the humidity sensor 60 is disposed between the driving assembly 43 and the air inlet, and thus the humidity sensor 60 can detect the humidity of the air flow before entering the driving assembly 43, and then timely control the working state of the dust collector 100 according to the humidity of the air flow, thereby avoiding the damage of the driving assembly 43 caused by water entering.
More specifically, the dirt cup assembly 41 includes a dirt cup 412, and a cyclone separator 414 and a filter structure 416 sequentially arranged in the dirt cup 412 from the air inlet to the air outlet, wherein the dirt cup 412 is integrally disposed with the main housing 20. The inventors have found in their studies that, because the cyclone 414 is of a more complex construction, the water entrained in the airflow entering the drive assembly 43 comes primarily from the cyclone 414 which is susceptible to water remaining after cleaning, and therefore the moisture sensor 60 is located within the dirt cup assembly 41 between the cyclone 414 and the filter arrangement 416. As such, the humidity sensor 60 may detect the humidity of the airflow exiting the cyclone 414 and not filtered by the filter structure 416, thereby improving the accuracy of the detection. Moreover, the filter structure 416 may provide some interception of water in the airflow, leaving water behind in the filter structure 416.
It will be appreciated that the location of the moisture sensor 60 is not limited thereto, and in other embodiments, the location of the moisture sensor 60 may be located between the filter structure 416 and the drive assembly 43, or other locations between the cyclone 414 and the drive assembly 43.
In some embodiments, the vacuum cleaner 100 includes a plurality of humidity sensors 60, and the plurality of humidity sensors 60 are circumferentially spaced from the wall of the accommodating chamber 21, so as to have high detection accuracy. It is understood that the number, installation position and installation manner of the humidity sensors 60 are not limited, and may be set as required to meet different requirements.
In some embodiments, the cleaner 100 further comprises an alarm module disposed in the main housing 20 and communicatively coupled to the control system. Thus, when the humidity sensor 60 detects that the humidity of the air flow in the accommodating cavity 21 is too high, the control system can control the alarm module to remind the user by emitting light, sound or vibration.
As shown in fig. 1 and 2, the method for controlling the vacuum cleaner 100 includes the following steps:
s110: real-time airflow humidity within the receiving cavity 21 of the main housing 20 of the cleaner 100 is obtained when the cleaner 100 is in an operating state.
Specifically, the humidity sensor 60 detects the real-time air flow humidity in the accommodating chamber 21 and sends a detection signal to the control system. Preferably, a humidity sensor 60 is positioned between the cyclone 414 and the filter structure 416, and the humidity sensor 60 senses the real-time humidity of the airflow obtained as a real-time humidity of the airflow passing through the cyclone 414.
S120: the operating state of the vacuum cleaner 100 is controlled based on the real-time airflow humidity level.
Specifically, the control system controls the operation of the vacuum cleaner 100 to stop or continue according to the acquired real-time air flow humidity, so as to avoid the damage of the driving assembly 43 caused by water inflow.
Specifically, in some embodiments, step S120 specifically includes the following steps:
s121: and comparing the real-time air flow humidity with the first preset air flow humidity.
Specifically, the control system compares the real-time airflow humidity with a first preset airflow humidity, wherein the specific value of the first preset airflow humidity can be set as required.
S122: when the real-time airflow humidity is judged to be larger than the first preset airflow humidity, controlling the dust collector 100 to stop running;
and when the real-time airflow humidity is judged to be smaller than the first preset airflow humidity, controlling the dust collector 100 to be continuously in the running state.
Specifically, when the control system determines that the real-time airflow humidity is greater than the first predetermined airflow humidity, indicating that an excessive amount of water remains in the cyclonic separator 414, the drive assembly 43 will be immediately damaged if the vacuum cleaner 100 continues to operate, and thus the control system controls the vacuum cleaner 100 to immediately stop operating to avoid damage to the drive assembly 43 by water ingress. When the control system determines that the real-time ambient humidity is less than the first predetermined ambient humidity, it indicates that the amount of water entering the driving assembly 43 does not exceed the safe amount for a certain period of time, and thus the control system controls the vacuum cleaner 100 to continue to operate. Wherein a portion of the water may be intercepted by the filter structure 416 during the period from the start of the operation of the vacuum cleaner 100 to the stop of the operation of the vacuum cleaner 100 controlled by the control system, thereby preventing the damage of the water entering the driving assembly 43.
In some embodiments, the step of controlling the vacuum cleaner 100 to continue operating when the real-time airflow humidity is determined to be less than the first predetermined airflow humidity further comprises the steps of:
s1221: when the real-time airflow humidity is less than the first preset airflow humidity, the vacuum cleaner 100 is controlled to be in an operating state and the real-time airflow humidity is compared with the second preset airflow humidity.
Specifically, when the control system determines that the real-time airflow humidity is less than the first predetermined airflow humidity, indicating that the moisture content of the dirt cup assembly 41 is low, the control system controls the vacuum cleaner 100 to be in an operating state and continues to compare the real-time airflow humidity with the second predetermined airflow humidity.
S1222: when the real-time airflow humidity is judged to be larger than the second preset airflow humidity, controlling the dust collector 100 to be in the running state and giving an alarm;
when the real-time airflow humidity is less than the second preset airflow humidity, the vacuum cleaner 100 is controlled to be in the running state
Specifically, when the control system determines that the real-time environmental humidity is greater than the second preset environmental humidity, it indicates that a certain amount of water still remains in the cyclone 414, and although the driving assembly 43 is not damaged immediately, if the vacuum cleaner 100 continues to operate for a certain time, the gradual accumulation of water in the driving assembly 43 still easily causes the driving assembly 43 to be damaged, so the control system controls the vacuum cleaner 100 to continue to operate normally, and controls the alarm device to give an alarm to remind the user that water remains in the cyclone 414. When the control system determines that the real-time ambient humidity is less than the second predetermined ambient humidity, it indicates that there is no water in the cyclone 414 or that the remaining water is low and does not exceed a safe amount, and therefore the control system controls the vacuum cleaner 100 to continue normal operation without causing damage to the drive assembly 43.
S1223: when the duration of the alarm sent by the dust collector 100 is longer than the preset time, the dust collector 100 is controlled to stop.
Specifically, when the user does not manage the alarm and does not stop the operation of the vacuum cleaner 100 in time, the control system obtains that the duration of the alarm sent by the vacuum cleaner 100 is longer than the preset time, and controls the vacuum cleaner 100 to stop the operation to avoid the driving assembly 43 from being damaged due to water erosion continuously.
The dust collector 100 and the control method thereof can remind a user whether the upstream environment of the driving assembly 43 is suitable for the driving assembly 43 to work or not in time, and the driving assembly 43 is prevented from being damaged by residual water caused by cleaning in the parts such as the cyclone separator 414, so that the service life of the dust collector 100 is prolonged, and the potential safety hazard of water inflow of the driving assembly 43 is eliminated.
The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention.
