Hereinafter, embodiments of the present application will be described in detail with reference to the accompanying drawings.
The up and down directions of the cleaning device are defined as shown in fig. 2.
Referring to fig. 1 to 3, a control method of a cleaning apparatus 100, the cleaning apparatus 100 includes a microbubble generation device 1, a washing drum 2, and a control system 3.
The microbubble generating device 1 is used for producing washing water containing microbubbles, the microbubble generating device 1 comprises a pressurized dissolved air part 11, a water inlet part 12 and a water outlet part 13, the water inlet part 12 and the water outlet part 13 are respectively communicated with the pressurized dissolved air part 11, the water inlet part 12 is connected with a tap water source, the water inlet part 12 is connected with a water inlet valve 121, the pressurized dissolved air part 11 further comprises a water drain pipe 14, the water drain pipe 14 is connected with a water drain valve 17, water enters the pressurized dissolved air part 11 from the water inlet part 12, and then flows out of the pressurized dissolved air part 11 from the water outlet part 13 or the water drain pipe 14. The washing drum 2 is used for washing a load, the drain pipe 14 is communicated with the washing drum 2, and when the drain valve 17 is opened, water in the pressurized dissolved air part 11 can be discharged to the washing drum 2 through the drain pipe 14. The control system 3 is configured to receive signals from the pressure sensor 4 and the water flow sensor 5, send out instructions according to analysis results after analysis, and the water inlet valve 121 and the water outlet valve 17 are respectively connected with the control system 3, where the control system 3 can control opening and closing of the water inlet valve 121 and the water outlet valve 17.
Referring to fig. 10, the control method of the cleaning apparatus 100 includes:
The cleaning apparatus 100 is started and the control system 3 controls the water inlet valve 121 to open and the water outlet valve 17 to close. Wherein, the water inlet valve 121 is opened to enable water to flow into the pressurized dissolved air part 11 from the water inlet part 12, air in the pressurized dissolved air part 11 is compressed to be dissolved in water, the water outlet valve 17 is closed to enable water in the pressurized dissolved air part 11 not to flow into the washing drum 2 from the water outlet pipe 14, water in the pressurized dissolved air part 11 only flows into the water outlet part 13, and water flow in the water outlet part 13 flows into the washing drum 2.
The control system 3 detects a water pressure value P in the pressurizing dissolved air part 11 and judges whether the P meets a preset condition value P0 or not; if P meets the preset condition value P0, the control system 3 prompts the user that the micro-bubble generating device 1 has no water flow.
It should be noted that, the preset condition value P0 is a water pressure value when no water flows through the pressurized dissolved air portion 11, and it is determined whether P meets the preset condition value P0, so that it can be determined whether water exists in the pressurized dissolved air portion 11, and the user is prompted to make the microbubble generating device 1 anhydrous, so that the user can be helped to know the working condition of the microbubble generating device 1, and can choose to observe whether the microbubble generating device 1 is connected with a water source according to the requirement of the user, or the control system 3 can choose to maintain the cleaning device 100 when no water flows are prompted for a long time.
If P does not meet the preset condition value P0, judging whether P meets the threshold condition 1. The threshold condition 1 is a threshold value at which the water pressure of the microbubble generating device 1 is kept in normal operation, and whether the water pressure of the microbubble generating device 1 is in normal operation can be determined according to whether P satisfies the threshold condition 1.
If P satisfies the threshold condition 1, the control system 3 detects the water flow L at the outlet of the microbubble generation device 1 and judges whether L satisfies the threshold condition 2. Since P satisfies the threshold condition 1, it can be determined that the water pressure of the microbubble generating device 1 is the water pressure during normal operation, and the control system 3 only needs to determine whether the microbubble generating device 1 flows out of the water flow, so as to determine whether the microbubble generating device 1 is operating normally to generate the water flow with normal pressure. The control system 3 determines whether the water of the microbubble generation device 1 flows normally by detecting the water flow rate L at the outlet of the microbubble generation device 1.
The threshold condition 2 is the water flow measured when the micro-bubble generating device 1 works normally, whether the micro-bubble generating device 1 has the normal water flow can be judged according to whether the L meets the threshold condition 2, the control system 3 can be helped to judge the water flow condition of the micro-bubble generating device 1, the steps are simple, and the operation is convenient.
If L meets the threshold condition 2, the control system 3 prompts the user to normally operate the microbubble generating device 1. And if L meets the threshold condition 2, the microbubble generating device 1 is proved to normally flow out of the water outlet part 13, then the microbubble generating device 1 has water flow in normal operation, and the combination P meets the threshold condition 1, so that the normal flow of the water flow in the microbubble generating device 1 and the normal water pressure are judged, and further, the abnormal condition that the water pressure is too high or the water flow is blocked due to blockage is judged, then the control system 3 prompts the user to normally operate the microbubble generating device 1, washing water carrying the microbubbles can be generated for the user, and the user can clearly know the operation condition of the microbubble generating device 1.
If L does not satisfy the threshold condition 2, the control system 3 prompts the user that the microbubble generation device 1 is blocked. If L does not satisfy the threshold condition 2, it is determined that the water flow from the water outlet portion 13 of the microbubble generating device 1 is abnormal, the microbubble generating device 1 does not have the water flow during normal operation, and if P satisfies the threshold condition 1, it is described that the water flow of the microbubble generating device 1 is abnormal but the water pressure is large, and then it is determined that the water flow of the microbubble generating device 1 is blocked to cause that the water cannot flow to generate large pressure, and the water flow of the microbubble generating device 1 is blocked and retained, then the control system 3 prompts the user that the microbubble generating device 1 is blocked. The user can clearly know that the micro-bubble generating device 1 is blocked, and can choose to stop the washing process for maintenance or to carry out other steps on the cleaning device 100 to solve the problem of blocking the micro-bubble generating device 1.
If P does not meet the threshold condition 1, the control system 3 detects the water flow L at the outlet of the micro-bubble generating device 1 and judges whether the water flow L meets the threshold condition 2. When the P does not meet the threshold condition 1, the threshold condition 1 is the water pressure value when the micro-bubble generating device 1 works normally, so that the abnormal high water pressure in the micro-bubble generating device 1 can be judged, and the micro-bubble generating device 1 is in an abnormal operation state. Further to determine the water flow rate of the micro-bubble generating device 1, the control system 3 can judge the operation condition of the micro-bubble generating device 1 according to the state of the water flow.
