[0032] The consumables feeding method of the cleaning machine in this embodiment:

[0033] (1) The user opens the door and places tableware in the bowl basket 3. At this time, the first control structure connects the liquid storage chamber 61 with the distribution chamber 62, and the consumables in the liquid storage chamber 61 enter the distribution chamber 62 and fill the distribution chamber 62, thereby achieving quantitative acquisition of consumables;

[0034] (2) When the user closes the door, the first control structure isolates the liquid storage chamber 61 from the distribution chamber 62 under the pressure of the inner wall of the door body 2; at this time, the second control structure 20 keeps the water inlet and the distribution chamber 62 isolated, and the bottom outlet 621 of the distribution chamber 62 is closed;

[0035] (3) Starting the washing process, controlling the water pressure to P1, the water pressure P1 drives the second control structure 20 to open the bottom outlet 621 of the distribution chamber 62, and the washing liquid in the distribution chamber 62 enters the washing chamber 11;

[0036] (4) The water pressure is controlled to be P2, P2>P1. The water pressure P2 drives the second control structure 20 to connect the water inlet with the distribution chamber 62. At this time, the bottom outlet 621 of the distribution chamber 62 also remains open.

The front side of the consumables delivery box 6 is also provided with a first control valve that can move forward and backward with the door body 2 to open or close the first liquid port 631 and the second liquid port 632. The first control valve 10 is the first control structure. With the above structure, it is convenient to realize whether to add liquid to the distribution chamber 62 through the door opening and closing action, so as to prepare a fixed amount of consumables for each operation of the dishwasher.

[0038] The first control valve 10 includes a first valve stem 101 and a first elastic member 102. The first valve stem 101 is inserted into the liquid guiding channel 63 from the front end thereof. A valve cap 1011 is provided at the front end of the first valve stem 101, which can press against the inner wall of the door body 2 in the closed state. The first elastic member 102 makes the first valve stem 101 always keep the tendency of moving forward to open the first liquid passage 631 and the second liquid passage 632. The second liquid passage 632 is arranged near the rear end of the liquid guiding channel 63, and the first liquid passage 631 is located at the front side of the second liquid passage 632. As the first valve stem 101 moves backward, not only can the first liquid passage 631 be closed to stop adding liquid to the distribution chamber 62, but also the backward movement of the first valve stem 101 can be used to squeeze the liquid in the liquid guiding channel 63 into the distribution chamber 62, so as to keep the liquid guiding channel 63 relatively hollow and not affect the next addition of liquid. When the door body 2 is opened, the first liquid passage port 631 and the second liquid passage port 632 are both in the open state, and the consumables in the liquid storage chamber 61 enter the distribution chamber 62 through the first liquid passage port 631 and the second liquid passage port 632. The volume of the distribution chamber 62 is the quantitative volume of the consumables to be put in at one time. When the door is closed, the door body 2 presses against the valve cap 1011 to push the first valve stem 101 backward until the first liquid passage port 631 is closed and the second liquid passage port 632 remains open, thereby interrupting the liquid storage chamber 61 from adding liquid to the distribution chamber 62, but allowing the remaining consumables in the liquid guide channel 63 to be sent to the distribution chamber 62, thereby avoiding the accumulation of consumables in the liquid guide channel 63 and improving the accuracy of the amount of consumables put in at one time.
