It should be noted that, in some other embodiments, the optical sensor 357 may be replaced by another detection device such as a hall sensor or a mechanical switch, and detect the opening and closing of the cover 340 by using a different principle. For example, the hall sensor is a magnetic sensor, and the magnetic field and the change thereof can be detected by the hall sensor, so that a magnet may be provided at the edge of the cover 340 on the side of the hall sensor, and in the case where the cover 340 completely closes the outlet, the magnet is opposite to the hall sensor, and the hall sensor can detect the magnetic field. For another example, the edge of the cover 340 on the side of the mechanical switch may be provided with an arm configured to: the mechanical switch is touched in a state where the cover 340 completely closes the outlet. Determining that the cover plate 340 completely closes the outlet of the ice passage 210 when the mechanical switch is touched by the arm; when the mechanical switch is not touched by the arm, it is determined that the cover plate 340 does not completely close the outlet of the ice passage 210.

In the above step, in step S708, it is determined whether the actual light intensity is smaller than the preset value, and if not, it indicates that the cover plate 340 does not completely close the outlet of the ice channel 210, which actually includes two cases: first, the cover plate 340 has not reached a position to close the outlet of the ice passage 210 during the upward movement; second, the cover plate 340 has reached a position to close the outlet of the ice passage 210, but cannot completely close the outlet. Therefore, it is necessary to perform step S712 and the following steps to further determine which case is.

The detection time period for the light sensor 357 to detect the actual light intensity is obtained in step S712, and the detection time period may actually be counted at the same time as the trigger signal for closing the outlet of the ice channel 210 is obtained in step S702. Step S714 determines whether the detection time is longer than the preset time, if so, it indicates that the cover plate 340 should have reached the position for closing the outlet of the ice channel 210 according to the normal condition, and at this time, the actual light intensity is still greater than or equal to the preset value, so that it can be determined that the cover plate 340 has reached the position for closing the outlet of the ice channel 210, but the outlet cannot be completely closed. Thus, step S716 is performed, it is determined that the cover plate 340 does not completely close the outlet of the ice chute 210, and the motor 330 is controlled to stop moving and to acquire the previous number of re-closing times in preparation for re-closing the outlet.

In step S718, it is determined whether the number of reclosing times is greater than the preset number of times, and if so, it indicates that the number of times of occurrence of the situation where the outlet cannot be completely closed by the front cover 340 is greater than the preset number of times, and that reclosing the outlet is basically useless, requiring a user to intervene in time. Therefore, step S720 is executed to control the ice making system 200 to stop making ice, and output an abnormal prompt message through a display device of the ice making system 200, so that the user can be timely reminded to check and repair, thereby avoiding loss. When the selection panel 220 mentioned above is a touch screen, the display device may also be the touch screen, and information such as characters or colors is output through the touch screen to prompt the user of an abnormality. In other embodiments, a sound message may be output by a buzzer or the like to prompt the user of the abnormality.

In step S718, it is determined whether the number of reclosing times is greater than the preset number, and if not, the number of occurrences indicating that the outlet cannot be completely closed by the front cover 340 is less than the preset number, and the outlet may be closed again after the outlet is attempted to be opened, so step S722 and the following steps are performed. Step S722 adds one to the number of reclosings, and then follows the step of reclosing, where the number of reclosings plus one is the time of the next reclosing that is added.

Step S724 drives the motor 330 to move in a second direction opposite to the first direction so that the cover plate 340 opens the outlet of the ice chute 210. That is, the motor 330 moves in the first direction, and the cover plate 340 moves upward to close the outlet of the ice chute 210; the motor 330 moves in the second direction and the cover plate 340 moves downward to open the outlet of the ice passage 210. The determination of whether the outlet of the ice passage 210 is completely opened in step S726 may be performed in various manners, such as moving the motor 330 in the second direction for a certain period of time or a certain number of steps, or moving the cover plate 340 downward to touch the inner wall of the housing 310. If the outlet of the ice chute 210 is completely opened, the driving motor 330 stops moving in step S728, and then returns to step S704, so that the cover 340 closes the outlet of the ice chute 210 again. If the outlet of the ice chute 210 is not completely opened, the process returns to step S724, and the motor 330 is continuously driven to move in the second direction, so that the cover plate 340 completely opens the outlet of the ice chute 210.

The control method of the dispenser of the ice making system of this embodiment obtains a trigger signal for closing the outlet of the ice channel 210, drives the motor 330 of the dispenser 300 to move in the first direction, so that the cover plate 340 closes the outlet of the ice channel 210, detects the actual light intensity by the light sensor 357, determines whether the actual light intensity is less than the preset value, and if so, determines that the cover plate 340 completely closes the outlet of the ice channel 210, and controls the motor 330 to stop moving. The opening and closing condition of the cover plate 340 of the distributor 300 can be detected quickly and effectively through the optical sensor 357, the problem that cold quantity leakage is caused when the cover plate 340 is not completely closed, even ice water, ice blocks or ice sand leakage is avoided, the distributor 300 can work normally, and the use experience of a user is improved.

Further, the method for controlling the dispenser of the ice making system according to this embodiment obtains a detection time period during which the optical sensor 357 detects the actual light intensity when the actual light intensity is greater than or equal to the preset value, determines whether the detection time period is greater than the preset time period, and if so, determines that the cover plate 340 does not completely close the outlet of the ice channel 210, controls the motor 330 to stop moving and obtains the previous re-closing times, and controls the ice making system 200 to stop making ice when the re-closing times are greater than the preset times, and outputs an abnormality prompt message through the display device of the ice making system 200. The user is reminded through the display device that the cover plate 340 of the dispenser 300 cannot completely close the outlet of the ice passage 210, so that the user can check the maintenance in time and avoid loss.
