Problems solved by technology

However, this single human body sensing method is prone to errors. For example, the entry of toilet cleaners may cause misjudgment; the failure of the sensing sensor may cause continuous flushing, resulting in waste of resources

Embodiment 1

[0058] A control method for automatic flushing of a toilet, control process reference figure 1 After powering on or restarting the toilet, connect the waterway, use the TDS module to detect the initial tds value T0 of the liquid seal, and add this value to the preset difference to obtain the critical value T1 for judging whether to automatically flush, and then start to detect whether take a seat. The TDS module can adopt conventional chip integration products, such as the miniature TDS flow sensor produced by Yihuan Technology. For toilets in the same area, because the water quality of the tap water is stable, a fixed value can also be preset, which is T1, and no calibration is performed when the power is turned on. In a specific embodiment, T0=90-110 unit ppm, T1=300 unit ppm.

[0059] Seat detection uses a seat sensor, such as the toilet seat sensor KMC01 provided by Zhanying Smart Sanitary Ware. The seating sensor can be arranged on the seat of the toilet, or the first ...

Embodiment 2

[0062] A control method for automatic flushing of a toilet, control process reference figure 2 , After powering on or restarting the toilet, connect the waterway, and use the TDS module to detect the tds value of the liquid seal. The TDS module can use conventional chip integration products, such as the miniature TDS flow sensor produced by Yihuan Technology.

[0063] After that, the seat detection is carried out. If the seat is detected, it will continue to detect whether it is seated; if the seat is not detected, the TDS value of the liquid seal is detected, which is recorded as X1. After that, the TDS value of the liquid seal is detected for the second time, which is recorded as X2. When X1-X2 When it is outside the preset range, control the toilet to flush after a delay. When X1-X2 is within the preset range, continue to detect the physical property Xn of the liquid level in the toilet until the difference between the adjacent two sides is within the preset value. When it...

Embodiment 3

[0066] A control method for automatic flushing of a toilet, control process reference image 3 , two difference values ​​are preset in the program. When the smart toilet is powered on, it will immediately detect the TDS value of the liquid seal, which is recorded as T0, and this value is added to the preset two difference values ​​to obtain the critical point for judging whether to automatically flush The value T1 and the critical value T2 for judging whether the toilet jumps out of the dead cycle when flushing is abnormal, and then starts to detect whether it is seated.

[0067] If it is detected to be seated, it will continue to detect whether it is out of the seat. If it is detected to be out of the seat, the flushing action will be performed and the TDS value detection will be performed. If there is a siphon formed, the electrodes are completely exposed to the air), if there is 0, then the off-seat flush procedure is completed, and the next big cycle starts, that is, the s...

Abstract

The invention relates to a control method and system for automatic flushing of a closestool and an intelligent closestool. The control method comprises the following steps of 1, powering the closestool; 2, detecting whether a human body sits or not through a first detection module, and detecting the physical property of liquid in the closestool through a second detection module; 3, when the firstdetection module does not detect that the human body sits on the seat and the second detection module detects that the physical attribute changes according with the condition, controlling the closestool to execute flushing, and returning the process to the step 2 after flushing is finished; and when it is not detected that the physical attributes change in accordance with the condition, repeatingthe step 2. The system comprises a sitting sensing module, a TDS detection module and a flushing control module. According to the control method for automatic flushing of the closestool, the use experience of the closestool can be improved, manual touch and pressing are not needed, sitting induction and physical properties for detecting the liquid level in the closestool are combined, accurate control is achieved, and use by a user is facilitated.

Description

technical field [0001] The invention relates to the technical field of toilet automatic control, in particular to a control method and system for automatic flushing of a toilet and an intelligent toilet. Background technique [0002] The toilet is also called the toilet, which is convenient for people's life. Since the toilet is installed on the ground, the height of the toilet itself is limited. In order to solve this problem, the most widely used and more comfortable solution on the market is to install a mechanical button or a capacitive foot sensor on the bottom of the toilet. When a man finishes urinating and needs to flush, he touches it with his foot. Foot feel, give the main board a flushing signal, so as to realize flushing, save the trouble of bending over, and greatly improve the convenience. [0003] However, whether it is a mechanical button or a capacitive foot feel, people need to make actions to send signals to the motherboard, which is still inconvenient an...
