In this application, there is no clear boundary between the water inlet section 123 and the diversion section 124. For the convenience of description, the section of pipeline near the water source is called the water inlet section 123, and the section near the ice maker 11 is called the guide section. The flow section 124, where the general trend of the water flow changes, is called the junction of the water inlet section 123 and the diversion section 124.

In addition, the extending direction of the water inlet section 123 is the direction in which water flows in the water inlet section 123, and the extending direction of the diversion section 124 is the direction in which water flows in the diversion section 124.

The section 123 extends in the same direction. This means that the extension direction of the buffer section 122 and the water inlet section 123 are substantially the same, so that after water flows into the buffer section 122, most of the water pressure is cancelled and the water flow direction changes, and then It flows away from the extension direction of the water inlet section 123 into the diversion section 124 and collides with the water in the water inlet section 123 to further reduce the water pressure.

Further, the inner diameter of the buffer portion 122 is greater than the inner diameter of the water inlet section 123, so that when water flows from the water inlet section 123 into the buffer portion 122, the water pressure decreases; of course, the inner diameter of the buffer portion 122 is also It may not be larger than the inner diameter of the water inlet section 123, and it can still offset most of the water pressure, which can also achieve the purpose of the present invention.
