Referring to fig. 1-3, fig. 1 is a schematic structural view of a surface cleaning apparatus in an embodiment of the present invention. Fig. 2 is a schematic structural diagram of a cleaning liquid supply system according to an embodiment. FIG. 3 is a schematic diagram of an embodiment of a bubble in the supply line located in the detection device. The direction of the arrows in the figure is the direction of the flow of the cleaning liquid, and the surface cleaning device may be a handheld, upright, horizontal or intelligent cleaning device, which is not limited in detail herein. The figure discloses a vertical surface cleaning device, the surface cleaning device 100 comprises a dirt recovery system and a cleaning liquid supply system, the cleaning liquid supply system comprises a clean water tank, a supply pipeline 2, a cleaning liquid distributor and a nozzle, liquid in the clean water tank passes through the supply pipeline 2 and then is sprayed onto a rolling brush or a surface to be cleaned through the nozzle, the surface is cleaned, and then the dirt recovery system recovers the cleaned dirt. The dirt recovery system comprises a suction nozzle arranged at the cleaning head, a sump 5 for recovering dirt, a motor assembly for generating a suction airflow, and a suction duct fluidly connecting the suction nozzle, the sump and the motor assembly. The suction airflow generated by the motor component enables dirt at the suction nozzle to flow into the sewage tank 5 through the suction pipeline, and after the dirt is subjected to gas-liquid separation in the sewage tank 5, the gas is discharged out of the equipment by the motor. The cleaning liquid supply system further comprises a detecting device 3 for detecting whether there is a flow of liquid in the supply line 2, the detecting device 3 emitting a corresponding detection signal, the detection signal comprising a first detection signal emitted by the detecting device 3 detecting that there is no flow of liquid in the supply line 2 and a second detection signal emitted by the detecting device 3 detecting that there is a flow of liquid in the supply line 2. The detection signal may be a voltage signal, a current signal, or other transmissible signals, which are not limited in detail herein, and only the signal is required to realize information transmission. In some specific embodiments, the detection device 3 may be a capacitive sensor or an optically coupled sensor. The specific structure of the capacitive sensor or the optical coupling sensor is not detailed here, and all the structures are common structures in the market. The principle is described below by taking an optical coupler type sensor as an example, the embodiment is not limited in detail, in the working process of the surface cleaning device, the cleaning liquid supply system starts to work, when liquid flows in the pipeline, the optical coupler type sensor can send a high voltage signal (relative to a low voltage signal below), when no liquid flows in the pipeline, the optical coupler type sensor can send a low voltage signal (relative to the high voltage signal), if liquid flows in the supply pipeline 2 all the time, the sensor can send a high voltage signal (a second detection signal) all the time, and at the moment, it is stated that cleaning liquid exists in the cleaning liquid tank 1 and does not need to be added. When no liquid flows in the pipeline, the signal sent by the sensor is changed from a high voltage signal (second detection signal) to a low voltage signal (first detection signal), and at this time, it indicates that no cleaning liquid is in the cleaning liquid tank 1. An alarm signal can be sent to remind the user to add the cleaning liquid. Of course, in order to ensure the accuracy of the detection result, the controller will generally control the alarm device to send out an alarm signal after the low voltage signal lasts for a period of time.
Referring to fig. 2 and 3, on the one hand, during use, since the cleaning liquid tank 1 may be moving, some bubbles may be generated in the cleaning liquid tank 1, or, in order to improve the cleaning effect, a cleaning agent is usually added to the cleaning liquid tank 1, most of the cleaning liquid generates a great amount of bubbles 6 in the cleaning liquid tank 1, and if these bubbles 6 continuously pass through the detection device 3, the detection device 3 will determine that there is no water or cleaning liquid in the cleaning liquid tank 1 and send an alarm signal to remind the user to add water, while actually there is cleaning liquid in the cleaning liquid tank 1. On the other hand, during the normal operation of the cleaning liquid supply system, in order to ensure that the water yield is not too large, the water is sprayed at intervals, for example, in the case of low gear (the suction force is small), the operation time of the water pump 4 is 124 ms every 3 s; in the high-end case (high suction), the water pump 4 is operated for 124 ms every 2 s. In the working process, when the water pump 4 is in a stop state and the air bubble 6 is just positioned at the detection device 3, at this time, the staying time of the air bubble 6 in the detection device 3 exceeds the preset alarm time of the detection device 3 (namely, the first detection signal lasts for the preset time), the alarm is triggered. On the other hand, if the liquid in the feed line 2 is completely emptied during the last cleaning, the feed line 2 between the cleaning liquid tank 1 and the detection device 3 will be filled with air, which also tends to cause false alarms.
To address the above-mentioned false alarm problem, the present invention provides a control method for a surface cleaning apparatus, and referring to fig. 4-5, fig. 4 is a flow chart of the control method in one embodiment. Fig. 5 is a flowchart of a control method in another embodiment. As shown in the figure, the control method comprises:
receiving or acquiring a detection signal sent by a detection device 3 in the supply pipeline 2; the detection signal includes a first detection signal and a second detection signal, the first detection signal is a signal generated by the detection device 3 detecting that no liquid flows in the supply pipeline 2, and the second detection signal is a signal generated by the detection device 3 detecting that liquid flows in the supply pipeline 2;
controlling the water pump 4 to work in different working modes according to different detection signals, wherein the different working modes comprise a first working mode and a second working mode; and the flow rate of the water pump 4 in the first working mode is greater than that in the second working mode within a preset time period. The flow rate is not limited to the actual flow rate through the water pump 4, and may be the actual volume of cleaning liquid passing through the water pump 4, or may be the theoretical flow rate of liquid pumped by the water pump 4 in a period of time. In one embodiment, the flow rate of the water pump 4 in the first mode of operation is greater than the flow rate in the second mode of operation over a period of 4-5 seconds. After first detected signal (lack of water signal) sent, improve water pump 4 through changing mode and extract the flow of detection device 3 with the cleaning solution from cleaning solution case 1, supply line 2 is full of the cleaning solution rapidly, can effectively reduce the probability that the wrong report takes place.
In one embodiment, the water pump 4 is continuously operated in the first operation mode. The water pump 4 is intermittently operated in the second working mode, specifically, the water pump 4 is fully opened and continuously operated in the first working mode, so that the liquid in the cleaning liquid tank 1 is rapidly conveyed to the nozzle, at the moment, when the liquid passes through the detection device 3, the detection device sends out a second detection signal, and the alarm device cannot send out an alarm signal. Even when air bubbles 6 are present in the supply line 2, they are quickly emptied, so that not only false alarms can be avoided, but also a sufficient supply of cleaning liquid can be ensured. The water pump 4 works intermittently under the second working mode, and the water pump 4 works intermittently, so that the water spraying amount can be effectively controlled.
Referring to fig. 4, in a further embodiment, after the water pump 4 is operated for a predetermined time, the first detection signal does not change to the second detection signal during the predetermined time, which indicates that the cleaning liquid tank 1 is empty of water and the cleaning liquid needs to be added. If the first detection signal becomes the second detection signal during this time period, the water pump 4 is operated in the second operation mode after the operation in the first operation mode is completed for the preset time period.
Referring to fig. 5, in another further embodiment, the water pump 4 is controlled to operate in the second operation mode immediately after the detection signal is changed from the first detection signal to the second detection signal during the period in which the water pump 4 operates in the first operation mode. Specifically, when the water pump 4 is used for rapidly conveying liquid in the first working mode, in order to avoid the excess amount of liquid sprayed by the nozzle, after the liquid flows through the detection device 3, the detection device 3 sends out a second detection signal, at this time, the water pump 4 is controlled to work in a second working mode (low flow rate), and the second working mode is the working mode of the water pump 4 when the equipment normally works.
Further, when the time that the water pump 4 works in the first working mode exceeds the preset time, the alarm device is controlled to send out an alarm signal. The preset time is 3-6 seconds. If the preset time is too short, false alarm is easy to occur when a large number of bubbles 6 exist; if the time is too long, the use experience is seriously influenced. Specifically, when the water pump 4 is operated in the first operation mode for more than a predetermined time, which indicates that no liquid flows through the pipes during the predetermined time, it is preliminarily determined that the cleaning liquid tank 1 is empty of cleaning liquid. If there is cleaning liquid in the cleaning liquid tank 1, then after this time period the continuous operation of the water pump 4 (operation at a high flow rate) has passed the detection device 3, the detection device 3 has also sent a second detection signal, and the controller, after receiving the second detection signal, controls the water pump 4 to operate in the second operation mode to reduce the flow rate of the water pump 4.
Of course, in other embodiments, the first operation mode may be intermittent operation or continuous operation, the second operation mode may be intermittent operation or continuous operation, and the two operation modes may be combined optionally, as long as it is ensured that the delivery rate of the water pump 4 in the first operation mode is greater than that of the water pump 4 in the second operation mode within a preset time period.
With continued reference to fig. 4-5, the present invention also provides a control method for a surface cleaning apparatus comprising:
receiving or acquiring a detection signal sent by a detection device 3 in the supply pipeline 2; the detection signal includes a first detection signal and a second detection signal, the first detection signal is a signal generated by the detection device 3 detecting that no liquid flows in the supply pipeline 2, and the second detection signal is a signal generated by the detection device 3 detecting that liquid flows in the supply pipeline 2;
controlling the water pump 4 to work in different working modes according to different detection signals, wherein the different working modes comprise a first working mode and a second working mode; the time for the water pump 4 to convey the liquid from the cleaning liquid tank 1 to the position of the detection device 3 in the first working mode is a first preset time, the time for the water pump 4 to convey the liquid from the cleaning liquid tank 1 to the position of the detection device 3 in the second working mode is a second preset time, and the first preset time is less than the second preset time.
The preset time may refer to a theoretical time, and may also be a time when the actual water pump 4 operates. In one embodiment, the flow rate of the water pump 4 in the first mode of operation is greater than the flow rate in the second mode of operation over a period of 4-5 seconds. In the case of a constant supply line 2, the first preset time is shorter by a second preset time. After first detected signal (lack of water signal) sends, improve water pump 4 through changing the operating mode and extract the cleaning solution from cleaning solution case 1 to detection device 3's flow, shorten the flow time of liquid in supply pipe 2, supply pipe 2 is full of with the cleaning solution rapidly, can effectively reduce the probability that the wrong report takes place.
In one embodiment, the water pump 4 is continuously operated in the first operation mode. The water pump 4 is intermittently operated in the second working mode, specifically, the water pump 4 is fully opened and continuously operated in the first working mode, so that the liquid in the cleaning liquid tank 1 is rapidly conveyed to the nozzle, and at the moment, when the fluid passes through the detection device 3, the alarm device cannot send out an alarm signal. Even when air bubbles 6 are present in the supply line 2, they are quickly emptied, so that not only a false alarm can be avoided, but also an adequate supply of cleaning liquid can be ensured. The water pump 4 works intermittently under the second working mode, and the water pump 4 works intermittently, so that the water spraying amount can be effectively controlled.
Referring to fig. 4, in a further embodiment, after the water pump 4 is operated in the first operation mode for a predetermined time, the first detection signal does not change to the second detection signal during the predetermined time, which indicates that the cleaning liquid tank 1 is empty of water and the cleaning liquid needs to be added. If the first detection signal becomes the second detection signal during this period of time, which indicates that cleaning liquid is being rapidly supplied to the detection device, which indicates that cleaning liquid is still present in the cleaning liquid tank, the first operation mode is operated after the water pump 4 has been operated in the first operation mode for a predetermined period of time.
Referring to fig. 5, in another further embodiment, the water pump 4 is controlled to operate in the second operation mode immediately after the detection signal is changed from the first detection signal to the second detection signal during the period in which the water pump 4 operates in the first operation mode. Specifically, when the water pump 4 is used for rapidly conveying liquid in the first working mode, in order to avoid the excess amount of liquid sprayed by the nozzle, after the liquid flows through the detection device 3, the detection device 3 sends out a second detection signal, at this time, the water pump 4 is controlled to work in a second working mode (low flow rate), and the second working mode is the working mode of the water pump 4 when the equipment normally works.
Further, when the time that the water pump 4 works in the first working mode exceeds the preset time, the alarm device is controlled to send out an alarm signal. The preset time is 3-6 seconds. The time is too short, false alarm is easy to happen when a large number of bubbles 6 exist, and the use experience is seriously influenced due to too long time. Specifically, when the water pump 4 is operated in the first operation mode for more than a predetermined time, which indicates that no liquid flows through the pipes during the predetermined time, it is determined that the cleaning liquid tank 1 is empty of cleaning liquid. If there is cleaning liquid in the cleaning liquid tank 1, then after the period of time the water pump 4 continues to operate, the cleaning liquid has reached the detecting device 3, the detecting device 3 has also sent the second detection signal, and the controller controls the water pump 4 to operate in the second operation mode after receiving the second detection signal, so as to reduce the flow rate of the water pump 4.
Of course, in other embodiments, the first operation mode may be intermittent operation or continuous operation, the second operation mode may be intermittent operation or continuous operation, and the two operation modes may be combined optionally, as long as it is ensured that the delivery rate of the water pump 4 in the first operation mode is greater than that of the water pump 4 in the second operation mode within a preset time period.
