The present invention is intended to be illustrative only and not to be construed as limiting the scope of the invention. Moreover, the terms "first" and "second" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.

[0027] Referring to FIG. 1 to FIG. 4, an embodiment of a water inlet method of a washing machine according to the present invention is provided. The washing machine is provided with a washing tub, a detergent box 1, and an inlet pipe for feeding water into the detergent box. Water valve, the washing machine is provided with a barrel water level sensor for measuring the water level in the detergent tub. The detergent box 1 can be pulled in the water tank 2, and a siphon tube 11 and a plurality of overflow ports 12 are arranged in the detergent box 1. The siphon tube 11 is fastened with a siphon cap, and the water absorption position is the upper end surface of the siphon tube 11. The flush water level, that is, when the water level in the detergent box 1 reaches the siphon level, the siphon tube 11 starts siphoning, so that the liquid in the detergent box 1 flows into the water tank through the siphon tube 11, and then flows into the washing tub; the overflow port 12 is set On the side wall of the detergent box 1, the overflow water level is a water level flush with the lower end surface of the overflow port 12, that is, when the water level in the detergent box 1 reaches the overflow water level, the liquid in the detergent box 1 is from The overflow port 12 flows into the water tank and flows into the washing tub. The overflow water level is higher than the siphon water level, that is, the siphon water level is first reached, the siphon is started, and the water is continuously fed through the inlet pipe to reach the overflow water level. [0028] Referring to FIG. 4, it is a flowchart of a water inlet method of the washing machine in this embodiment, which specifically includes the following steps:

[0029] A, mixing water step, slamming the water inlet valve, start to feed water into the detergent box 1, when the water level continues to rise to reach the siphon liquid level, start siphoning; continue to enter the water, after reaching the overflow water level, Most of the fully diluted mixture flows away from the overflow 12.

[0030] Specifically, by setting the mixing water inlet step, on the other hand, the speed of the water entering the washing machine can be increased. Since the speed of the siphon entering the water is too slow, such as all water entering through the siphon, the water inlet is too long and prolonged. The overall washing compartment of the washing machine; most of the water in the mixing water inlet step flows into the washing tub through the overflow port 12. On the other hand, the washing water flowing out of the siphon pipe 11 is sucked up from the bottom of the detergent box 1 into the siphon pipe 11, and the detergent is poured into the bottom of the detergent box after being poured into the detergent box 1, thereby causing the concentration of the washing water flowing out from the siphon pipe 1 to be larger than The concentration of the washing water flowing out from the overflow port 12; and the washing water flowing out from the siphon pipe 1 and the washing water flowing out from the overflow port 12 are mixed in the water tank 2 and then flow into the washing tub, that is, the washing liquid reaching the washing tub has already been After sufficient dilution, it will spill on the clothes in the washing tub without causing damage to the clothes.

[0031] B, siphon water inlet step, first control to close the inlet valve, water level overflow from the overflow will gradually fall back below the overflow, stop the overflow; but the siphon continues, until the siphon will leave the remaining liquid in the detergent box Drain or stop the siphon.

[0032] Specifically, the siphon pipe 11 is sucked upward from the bottom of the detergent box 1 only by siphoning water, so that the water flows through the bottom of the detergent box 1 to dissolve a part of the adhered detergent; and in the detergent box 1 After the washing water is completely discharged into the washing tub through the siphon pipe 11, the water inlet valve is sucked into the water, and the influent water is directly splashed on the detergent adhered to the bottom of the detergent box 1, thereby accelerating the dissolution of the detergent. Thus, by siphoning the water ingress step B, the detergent in the detergent box 1 is sufficiently dissolved to prevent the detergent from remaining in the detergent box, improving the utilization rate of the detergent, and the rinse-cleaning ratio of the laundry.

[0033] Step C: Repeat steps N and B N times to complete the water intake of the washing machine.

[0034] By repeating the AB water inflow step a plurality of times through the step C, it is possible to solve the problem that the detergent which is deposited on the bottom of the cavity cannot be diluted/overflow/siphon cleaned by a single uninterrupted and non-repetitive water inlet, which is beneficial to the detergent. Dissolve, through a number of cycles, the detergent in the cavity can be washed out to the utmost extent.

[0035] In the embodiment, the mixing water inlet step is controlled by controlling the first smashing interval T1 of the water inlet valve. The crucible is continued, and the first smashing room T1 is larger than the water level of the liquid entering the detergent box 1 through the water inlet pipe to reach the turbulent level of the overflow water level. For example, the water level of the liquid entering the detergent box 1 through the water inlet pipe reaches 0.5% of the overflow water level, and the first smashing room T1 can be set to 1 to 3 minutes, and the first snoring is started in the water inlet valve. After the T1 in the day, close the inlet valve and proceed to step B.

[0036] In step B, the continuous turn of step B is controlled by controlling the second closing turn T2 of the water inlet valve. That is, after the water inlet valve is closed, the washing water in the detergent box 1 is completely discharged into the washing tub through the siphon tube 11, that is, the second closing chamber T2 is equal to or larger than the washing water in the detergent box 1 and is completely discharged through the siphon tube 11. In the daytime, for example, the washing water in the detergent box 1 is all discharged through the siphon 11 for 5 seconds, and the T2 can be set to 5 to 10 seconds.

[0037] In the present embodiment, in step C, N is greater than or equal to two times, and by repeating steps A and B, the detergent in the detergent box 1 is further promoted to be sufficiently dissolved to prevent the detergent from remaining in the detergent box 1. Improve the utilization of detergents, as well as the rinse-off ratio of clothes

[0038] In the embodiment, in step C, the water inlet is stopped after the water level in the washing tub reaches the set water level, and the water inlet step is completed.

[0039] In the present embodiment, the water inlet mode of the water inlet pipe is not limited, and may be a shower member disposed above the detergent box 1, or may be provided on the side wall or the bottom wall of the detergent box. The water inlet on the water, etc.
