When the external water pipe is damaged to cause slow leakage of liquid, the water pressure in the external water pipe is slowly reduced, the high-voltage switch is continuously triggered to stop, at the moment, the liquid in the pressure-maintaining air bag box is supplemented into the waterway due to shrinkage of the air bag, the reducing speed of the water pressure in the waterway is slowed down, when the liquid in the pressure-maintaining air bag box cannot supplement the liquid into the waterway, the water pressure in the waterway continuously drops along with the leakage of the water pipe until reaching the triggering threshold value of the low-voltage switch, and the main controller records the first time difference t of the change of the triggering state of the high-voltage switch and the change of the triggering state of the low-voltage switch 1 The first time difference t 1 If the water pipe leakage is within the first preset range, the water pipe leakage is considered to be leaked, and a water pipe leakage alarm signal is sent, wherein the first preset range can be set according to experimental data, for example, the time is greater than 10 seconds, and when t 1 If the water leakage is more than 10 seconds, the water leakage is considered to be the water leakage, and a water leakage alarm signal is sent out, for example, a water leakage signal lamp is lightened and/or a buzzer alarm is sent out.
In some embodiments, when the external water pipe leaks due to rupture, if the rupture is not large enough but is not in a tiny leakage state, the water pressure in the external water pipe also rapidly decreases, the high-pressure switch is continuously triggered to stop, at this time, the liquid in the pressure maintaining air bag box is replenished into the waterway due to shrinkage of the air bag, the pressure maintaining air bag box only slows down the speed of decreasing the water pressure in the waterway in a short time due to the rapid water leakage in the external water pipe, when the liquid in the pressure maintaining air bag box cannot replenish the liquid in the waterway, the water pressure in the waterway rapidly decreases along with the rupture of the water pipe, the trigger threshold of the low-pressure switch is reached in a short time, and the main controller records the second time difference t between the high-pressure switch and the low-pressure switch being triggered 2 The second time difference t 2 And if the water pipe is broken within the second preset range, sending out a water pipe breakage alarm signal. For example, the second preset range may be set according to experimental dataFor example 3-10 seconds, when t 2 At 3-10 seconds, it is considered that the water pipe breaks, and a water pipe break alarm signal is sent out, for example, a water pipe break signal lamp is turned on and/or a buzzer alarm is sent out.
In some embodiments, when the second electromagnetic valve of the fresh water tank is opened to supplement water normally, the water pressure in the external water pipe is reduced rapidly, the high-voltage switch is continuously triggered to be stopped, at this time, the liquid in the pressure maintaining air bag box is supplemented into the waterway due to shrinkage of the air bag, the pressure maintaining air bag box only can reduce the reducing speed of the water pressure in the waterway in a transient manner due to the very fast water flow in the external water pipe, when the liquid in the pressure maintaining air bag box cannot supplement the liquid in the waterway, the water pressure in the waterway reaches the trigger threshold of the low-voltage switch in a very short time, and the main controller records the third time difference t between the high-voltage switch and the low-voltage switch which is triggered 3 The third time difference t 3 And if the water is in the third preset range, the water is considered to be normally replenished, no alarm signal is sent out, and a normal replenishing signal can be sent out. Wherein the third preset range can be set according to experimental data, such as 0-3 seconds, when t 3 And when the water is in the range of 0-3 seconds, the water is considered to be normally replenished, a normal replenishing signal is sent out, for example, a normal replenishing signal lamp is turned on, and the normal replenishing signal lamp is turned off after the replenishing is finished.
In some embodiments, when the external water pipe is broken to cause rapid leakage of liquid, at this time, the water pipe is broken to cause serious water leakage, and the triggering interval of the high-low pressure trigger switch is close to that of the second electromagnetic valve when the second electromagnetic valve is opened during normal water supplementing, for example, the trigger interval is also in a third preset range, and the main controller cannot judge whether the water pipe is normal water supplementing or the water pipe is broken, at this time, the control can be controlled by the following control logic. The master box is further configured to: the second electromagnetic valve is closed in a first preset time period, and the first electromagnetic valve is closed in a second preset time period, wherein the second preset time period at least partially overlaps with the first preset time period; and in the time period of which the second preset time period is overlapped with 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 portion of the second preset time period being the first preset time period.
As shown in fig. 12, whether or not the water pipe is broken can be described by a timing chart. When the water level of the clean water tank reaches the water-free hall detection position, the second electromagnetic valve of the clean water tank is opened, the time is recorded as 0 th second, the 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 st second, the water in the faucet is supplemented into the pipeline, the second electromagnetic valve is closed, the time is recorded as 1.5 th second, the first electromagnetic valve is closed after a preset time, the time is recorded as 3 rd second, the first electromagnetic valve is closed after the second electromagnetic valve is closed for 1.5 seconds, the water is kept at a high pressure in the pipeline, namely, the water is filled for a period of time, such as 2 seconds, before each water supplement, whether the high pressure state can be maintained in the pipeline is detected, the first electromagnetic valve is closed for 1 second, the time is recorded as 4 th second, the water in the pipeline is supplemented into the pipeline within 1 second, if the pipeline is not broken, the high pressure in the pipeline is not maintained if the pipeline is broken, and therefore, the water can not break state can be judged if the high pressure state is reached in the time. The second solenoid valve is then opened to begin normal replenishment until the fresh water tank is full, for example, at 5 seconds, and closed. Therefore, the problem that water leakage is more serious due to continuous water supplementing under the condition that a water pipe is broken can be avoided.
