In some optional embodiments, a higher technical effect may be achieved by further optimizing and configuring the above steps, and the following describes in detail the method for detecting an abnormality of a water circuit according to this embodiment in combination with a description of an optional execution flow of this embodiment, where this embodiment is merely an illustration of the execution flow, and in a specific implementation, an execution sequence and an operation condition of a part of steps may be modified according to specific implementation requirements. Fig. 4 is a detailed flowchart of an abnormality detection method of a water path according to an embodiment of the present invention. The water path 100 in this embodiment may further include an external water source 110 and a water using component, in addition to the total water valve 120 and the plurality of pressure sensors 220, which are respectively disposed at two sides of the total water valve 120, one pressure sensor 220 is disposed between the total water valve 120 and the external water source 110, the first pressure value is acquired, and the other pressure sensors 220 are disposed at the other side of the total water valve 120. The method for detecting the abnormality of the water path comprises the following steps:
step S402, acquiring a plurality of pressure values by using a plurality of pressure sensors 220;
step S404, acquiring the opening and closing state of the total water valve 120;
step S406, determining whether the total water valve 120 is opened, if yes, performing step S408, and if not, performing step S418;

In the above steps, step S410 determines whether the difference between each pressure value and the average value is smaller than the preset pressure difference, and if yes, step S412 is executed to determine that the waterway 100 is normal. That is, the waterway 100 may be determined to be normal as long as each pressure value is around the average value. In other embodiments, even if the difference between each pressure value and the average value is smaller than the preset pressure difference, it may be further determined whether each pressure value is stable, for example, the fluctuation of each pressure value is small in a predetermined time, that is, it may be determined that the pressure value is stable, so that the waterway 100 is further determined to be normal according to the stability of each pressure value on the basis that each pressure value is around the average value.
In step S416, the total water valve 120 is controlled to close and output an alarm message to alert the user that the waterway 100 is abnormal. Since the water path 100 of the present embodiment can be applied to a refrigerating and freezing device, when the refrigerating and freezing device is provided with a display device or a buzzer, an alarm can be given by using the display device or the buzzer. In addition, when the waterway 100 is provided with the shunt valve 140 so that the water flows to different water consuming parts, the shunt valve 140 can be controlled to be closed while the main water valve 120 is controlled to be closed.
According to the method for detecting the abnormality of the water path, different ways of determining the abnormality of the water path 100 are adopted according to different opening and closing states of the water main valve 120, that is, the whole water path 100 can be detected under any condition, whether water leakage occurs between the water main valve 120 and the external water source 110 and between the water main valve 120 and the water using component is determined, and the water main valve 120 is closed in time and an alarm is given when the water path 100 is abnormal, so that the loss caused by the water leakage is effectively reduced, the user is reminded, and the use experience of the user is improved.

The condition determination module 340 may be configured to determine that the water circuit 100 is abnormal when an absolute value of a difference between any one of the pressure values and the average value is greater than or equal to a preset pressure difference. In practice, it is determined that an abnormality occurs in the water circuit 100 when at least one pressure value has a large deviation from the average value. If the preset pressure difference is set too large, the water path 100 may be slightly abnormal and cannot be found in time; if the preset pressure difference is too small, an abnormality may be reported when the water passage 100 slightly fluctuates, and a false alarm may be given. Therefore, the preset pressure difference can be set according to actual conditions, and the purposes of timely finding abnormality and avoiding false alarm are achieved.
