[0016] Figure 4 This is a schematic diagram of the integrated three-zone drum washing machine of this utility model. Detailed implementation method:
[0017] The present invention will be further described below with reference to the accompanying drawings.
[0018] The water system structure of this utility model's integrated three-zone drum washing machine includes a water inlet structure, a drainage structure, and an automatic dispensing box. The automatic dispensing box includes a left automatic dispensing box 7 and a right automatic dispensing box 8. The washing machine includes a large tub and two smaller tubs located above the large tub, a left smaller tub and a right smaller tub.
[0019] The water inlet structure includes a water distributor 1, an inlet valve 2 and a reversing valve 15 installed on the water distributor 1, and an inlet pipe 3 connected to the inlet valve 2. The other end of the inlet pipe 3 is connected to the left automatic dispensing box 7. A first water pipe 4 is connected to the left automatic dispensing box 7, and the other end of the first water pipe 4 is connected to the right automatic dispensing box 8. A second water pipe 5 is connected to the right automatic dispensing box 8, and the other end of the second water pipe 5 is connected to the water distributor 1. The water distributor 1 is also connected to a first spray pipe 9, a second spray pipe 10, and a third spray pipe 11, wherein the first spray pipe 9 is connected to the large bucket, the second spray pipe 10 is connected to the left small bucket, and the third spray pipe 11 is connected to the right small bucket.
[0020] The water flow process in the water inlet structure is as follows: Tap water flows into the distributor after being controlled by the inlet valve, then flows into the left automatic dispensing box 7 through the inlet pipe 3, and then flows into the right automatic dispensing box 8 through the first water pipe 4. Finally, the mixed liquid, which contains liquids from the left and right automatic dispensing boxes 7 and 8, flows into the distributor 1 through the second water pipe 5. By controlling the reversing valve on the distributor 1, the mixed liquid enters the large tank through the first spray pipe 9, the left small tank through the second spray pipe 10, and the right small tank through the third spray pipe 11.
[0021] The drainage structure comprises an upper bucket drainage module 12, a lower bucket drainage module 13, and a water collection box 14. The upper bucket drainage module 12 consists of a drainage corrugated pipe 120, a drain valve 121, and an inner drain pipe 122 within the upper bucket. There are two drainage corrugated pipes 120, connected to the left and right small buckets respectively. The other ends of the two drainage corrugated pipes 120 are each connected to a drain valve 121, and each drain valve 121 is connected to an inner drain pipe 122 within the upper bucket. The two inner drain pipes 122 are connected to two interfaces on the water collection box 14. When the upper left and right buckets drain, wastewater enters the drain valves 121 through the drainage corrugated pipes 120. When the drain valves 121 are open, the wastewater enters the water collection box 14 through the inner drain pipes 122 within the upper buckets. The use of drain valves for upper bucket drainage allows for independent drainage of the two buckets, achieving physical isolation, preventing cross-contamination, and simplifying the water path layout, thus saving space.
[0022] The lower bucket drainage module 13 consists of a lower bucket drainage pump 130 and a lower bucket drainage pipe 131. During lower bucket drainage, the impeller in the lower bucket drainage pump 130 operates to draw out wastewater, which enters the water collection box 14 through the lower bucket drainage pipe 131 and is discharged from the machine body.
[0023] The water collection box 14 is divided into three chambers by ribs, so that the drainage of the three buckets does not interfere with each other and avoids water mixing.
[0024] This utility model features an integrated three-zone drum washing machine with a water circuit structure. The left and right small drums use two identical drain valves, and a new centralized box structure is added. The dual drain valves are independently controlled, achieving physical isolation and preventing cross-contamination between the two drums from the source. The water distributor design simplifies the entire pipeline, avoiding excessively long pipes while simultaneously accommodating the inlet and outlet of all three drums, reducing unnecessary water and energy losses.
[0025] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements can be made without departing from the principle of the present utility model, and these improvements should also be considered within the protection scope of the present utility model.
