[0011] As a further solution of the present invention: the step of controlling the water injection timing in step S1 is: the control module sends a water injection instruction to the water pump so that water is injected into the ice box of the ice-making equipment through the inlet and outlet water pipes, and controls the start and stop water injection cycle to be T0.

[0012] As a further solution of the present invention: the step of controlling the pressure sensor to start detection in step S2 is: setting a pressure sensor below the water outlet, and within the water injection timing duration T0 and the time T1 after the water injection is completed, the pressure sensor obtains pressure detection data every interval T3, and uploads it as feedback to the control module.

[0013] The step of determining the water injection status of the inlet and outlet water pipes in step S3 is as follows: within the water injection timing duration T0 and the time duration T1 after the water injection is completed, the relationship between the pressure sensor detection parameter and the timing satisfies the change relationship of 0-X1-0, then it is determined that the water injection status of the inlet and outlet water pipes is a normal water injection status.

[0014] As a further solution of the present invention: within the water injection timing duration T0 and the time T1 after the water injection is completed, the relationship between the pressure sensor detection parameters and the timing satisfies the change relationship of 0-X2-X3-0, where X3<X2, then it is determined that the water injection state of the inlet and outlet water pipes is a partially ice-blocked water injection state.

[0035] See also Figure 1 As shown, the present invention is a control method for detecting ice blocking faults, comprising the following steps:

[0036] S1. Respond to the water injection instruction and control the water injection timing; specifically, the control module sends a water injection instruction to the water pump so that water is injected into the ice box of the ice-making equipment through the inlet and outlet water pipes, and controls the start and stop water injection cycle to be T0.

[0037] S2. When the water injection timing starts, according to the water injection timing duration T0 and the time after the water injection is completed T1, control the pressure sensor to start detection, and obtain the relationship between the pressure sensor detection parameters and the timing; specifically, a pressure sensor is set below the water outlet, and within the water injection timing duration T0 and the time after the water injection is completed T1, the pressure sensor obtains pressure detection data every T3 interval, and uploads the feedback to the control module.

[0038] S3. Combination Figures 2 to 4 As shown, the water injection state of the inlet and outlet water pipes is determined according to the relationship between the pressure sensor detection parameters and the timing; specifically, within the water injection timing duration T0 and within the time T1 after the water injection is completed, the relationship between the pressure sensor detection parameters and the timing satisfies the change relationship of 0-X1-0, then the water injection state of the inlet and outlet water pipes is judged to be a normal water injection state; within the water injection timing duration T0 and within the time T1 after the water injection is completed, the relationship between the pressure sensor detection parameters and the timing satisfies the change relationship of 0-X2-X3-0, wherein X3<X2, then the water injection state of the inlet and outlet water pipes is judged to be a partially ice-blocked water injection state; within the water injection timing duration T0 and within the time T1 after the water injection is completed, the relationship between the pressure sensor detection parameters and the timing satisfies the change relationship of 0-X4, then the water injection state of the inlet and outlet water pipes is judged to be a completely ice-blocked water injection state.

[0039] S4. Controlling whether the ice-making display panel displays a fault code according to the water injection status of the inlet and outlet water pipes; specifically, controlling the ice-making display panel to display a fault code according to whether the water injection status of the inlet and outlet water pipes is a complete ice-blocked water injection status and / or a partial ice-blocked water injection status; controlling the ice-making display panel not to display a fault code according to whether the water injection status of the inlet and outlet water pipes is a normal water injection status.

[0040] During the use of the control method of the present application, the specific operations are as follows: by placing a pressure sensor at the water outlet, responding to the water injection command, starting the water injection to stop the predetermined cycle time T0 is 40s, the pressure sensor can be turned on after the 10th second, and recording the pressure detection data every 0.5s, and uploading the feedback to the control module. During the detection and recording process, the time T1 after the water injection is completed is 80s. It can be seen that the detection time of the pressure sensor is 120s. The values ​​obtained in real time by the pressure sensor are analyzed within the detection time of 120s. If the relationship between the pressure sensor detection parameters and the timing satisfies the change relationship of 0-X1-0, that is, from 40s to 60s after the injection is completed During the time, the pressure value is still 0, then it is judged that the water injection state of the inlet and outlet water pipes is a normal water injection state; if the relationship between the pressure sensor detection parameters and the timing satisfies the change relationship of 0-X2-X3-0, where X3<X2, due to partial ice blockage, the corresponding value of the pressure sensor from 40s to 60s is a linear decrease relationship of X2-X3-0, then it is judged that the water injection state of the inlet and outlet water pipes is a partial ice blockage water injection state; if the relationship between the pressure sensor detection parameters and the timing satisfies the change relationship of 0-X4, that is, the pressure value will not change within 40s to 60s after the injection is completed, then it is judged that the water injection state of the inlet and outlet water pipes is a complete ice blockage water injection state.

[0041] The control method of the present application can be used to actively analyze whether the water pipe is blocked by ice and upload the fault code. This can improve the monitoring accuracy of load operation and the efficiency of subsequent maintenance without increasing any cost.
