Wherein the third predetermined range can be set according to experimental data, such as 0-3 seconds, when t 3 And when the water is supplemented for 0-3 seconds, the water is considered to be normally supplemented, a normal water supplementing signal is sent, for example, a normal water supplementing signal lamp is turned on, and the normal water supplementing signal lamp is turned off after the water is supplemented.
In some embodiments, when the external water pipe causes rapid liquid leakage due to breakage, at this time, the water pipe breakage causes serious water leakage, and the trigger interval to the high-low pressure trigger switch is close to that when the second electromagnetic valve is opened during normal water replenishing, for example, also within a third preset range, the main controller cannot judge whether normal water replenishing or water pipe breakage occurs, and at this time, the control may be performed through the following control logic. The master control box is further configured to: the second electromagnetic valve is closed within a first preset time period, and the first electromagnetic valve is closed within a second preset time period, wherein the second preset time period is at least partially overlapped with the first preset time period; and in a time period overlapping the second preset time period and the first preset time period, the high-voltage switch is continuously triggered, and the water pipe is judged to be not broken. The at least partial overlap may be a fraction of the second preset time period being the first preset time period.
As shown in fig. 12, the detection of the presence or absence of a water pipe breakage can be described by a timing chart. When the water level of the clean water tank reaches the no-water Hall detection position, the second electromagnetic valve of the clean water tank is opened, the time is recorded as 0 second, water in the pipeline is released, the pressure in the pipeline is reduced, the low-pressure switch is triggered, the first electromagnetic valve is opened, the time is recorded as 1 second, for example, water in the faucet is replenished into the pipeline, the second electromagnetic valve is closed, the time is recorded as 1.5 seconds, for example, after the preset time, the first electromagnetic valve is closed, the time is recorded as 3 seconds, namely, after the second electromagnetic valve is closed, water is continuously filled for 1.5 seconds, the first electromagnetic valve is closed, the high pressure is kept in the pipeline in the time period, namely, the water is filled for a period of time, for example, 2 seconds, before each water replenishing, whether the high-pressure state in the pipeline can be maintained, the first electromagnetic valve is closed for 1 second, the first electromagnetic valve is opened, the time is recorded as 4 seconds, the water is kept in the 1 second period when the first electromagnetic valve and the second electromagnetic valve are both closed, if the pipeline is not damaged, the high-pressure in the pipeline is maintained, and the high-pressure in the pipeline is not broken, therefore, the high-pressure in the time period, if the pipeline can be maintained, no-break is reached, the no-break condition can be determined, and the no-break condition of the water is realized. Then, the second electromagnetic valve is opened at, for example, 5 th second to start normal water replenishing, and the second electromagnetic valve is closed until the clean water tank is full of water. Therefore, the problem that the water leakage phenomenon is more and more serious due to continuous water supplement under the condition that the water pipe is broken can be avoided.
