However, when the ice tray 05 is taken out for cleaning, due to long-time use and abrasion, the knob may loosen and fall horizontally instead of in the vertical direction, at the moment, water is injected into the ice storage box, and icing causes customer complaints; in addition, after the ice tray is cleaned, a user forgets to rotate the knob 0 to the horizontal position, so that the feedback signal is taken out of the ice tray, and water cannot be normally injected to make ice.
However, in this example, the ice maker is designed with a new installation manner of the magnetic sensitive switch, as shown in fig. 10 and 11, the ice maker 14 further includes a magnet 26 and a magnetic sensitive switch 17, the magnet 26 is disposed on the ice tray support 22, the magnetic sensitive switch 17 is disposed on the bottom of the partition board 1, the magnet 26 and the magnetic sensitive switch 17 are disposed correspondingly, and the two are mutually inductive and used for sensing whether the ice tray 23 is taken out in a matched manner to judge whether water injection is stopped or not, so as to accurately complete a series of water injection and ice making actions, and the reliability is high.
