[0074] A liquid level monitoring device 8 is installed within the drawer lower cover 21 to detect the liquid level within the detergent chamber 211. The liquid level monitoring device 8 includes a float, a sensor, and wiring. A float support column 216 is mounted on the drawer lower cover 21. The float is mounted on the support column 216 and moves up and down along the support column 216. A sensor is fixed to the bottom surface of the sink 1, below the float. Wiring runs along the sink 1 and the waterway plate 4, connecting the sensor to the washing machine control panel and transmitting the sensor's sensing signal to the washing machine control panel.

[0075] The working process of the present invention is as follows:

[0076] By controlling the first solenoid valve body 62 or the second solenoid valve body 63 in the water inlet valve 6, the valve seat water inlet 611 is connected to the first valve seat water outlet 612 or the second valve seat water outlet 613, so that the incoming water enters the first waterway 45 through the first water inlet 43, or enters the second waterway 46 through the second water inlet 44.

[0077] When detergent is used for washing, the liquid pump 3 is started, and the detergent in the detergent chamber 211 enters the liquid pump 3 through the liquid inlet nozzle 53 and the suction chamber 51 of the converter 5, and is sent to the discharge chamber 52 by the liquid pump 3, and is discharged into the water tank chamber 11 from the detergent discharge nozzle 56.

[0078] When first solenoid valve body 62 is opened, water enters first water path 45 through first water inlet 43. Water in first water path 45 can then flow directly into water tank chamber 11 through flushing port 47, or into detergent chamber 213 through detergent chamber inlet 412, and then into water tank chamber 11 through detergent chamber outlet 215, and then be discharged through water outlet 13 of water tank chamber 11. When water flows through flushing port 47, since flushing port 47 is located above detergent discharge nozzle 56, the water flow can flush out the discharged detergent, thereby improving the dissolution efficiency of the detergent in the water.

[0079] When softener needs to be added, the second solenoid valve body 63 opens, allowing the incoming water to enter the second water path 46 along the second water inlet 44. The second water path 46 enters the softener chamber 212 through the softener chamber water inlet 411 and the softener addition port 222, and enters the water tank chamber 11 under the action of siphon, and is discharged through the water outlet 13 of the water tank chamber 11.

[0080] When washing with detergent, the first solenoid valve body 62 opens to allow water to enter the first water channel 45 along the first water inlet 43. The water in the first water channel 45 enters the detergent chamber 213 through the detergent chamber inlet 412 to dissolve the detergent, and is discharged into the sink chamber 11 through the detergent chamber outlet 215.

[0081] The user can add detergent, softener, and washing powder through the drawer assembly 2. Pull the drawer assembly 2 outward, and the limit buckle 7 on the drawer cover 22 slides along the drawer guide groove 48 on the water channel bottom plate 41. The limit plate 49 engages with the limit buckle part 72 to prevent the drawer assembly 2 from separating from the sink 1. The user can add detergent, softener, and washing powder into the detergent chamber 211, softener chamber 212, and washing powder chamber 213 through the detergent inlet 221, softener inlet 222, and washing powder inlet 223. After the user has added detergent in one go, the liquid pump 3 automatically adds detergent, eliminating the need for multiple additions. When the remaining detergent in the detergent chamber 211 is less than the single-use amount, the sensor and float sense the machine, and an alarm automatically sounds, reminding the user to add detergent. Softener and washing powder can be added before washing according to user needs.

[0082] Compared with the prior art, the detergent smart dispensing box provided by the present invention has the following advantages:

[0083] (1) The first water inlet, the second water inlet, the first water channel and the second water channel are provided on the water channel plate, so that the water inlet is connected to the water tank cavity and the washing powder cavity respectively. The detergent in the detergent cavity can be automatically put into the water tank through the adapter and the liquid pump, so that a single liquid pump can control the automatic dispensing of multiple detergents, simplifying the structure of the detergent intelligent dispensing box, reducing the production cost of the detergent intelligent dispensing box, and having good economy and practicality;

[0084] (2) A liquid level monitoring device is provided in the lower cover of the drawer. The liquid level in the detergent chamber is detected by a float and a sensor. An alarm is sounded when the remaining detergent in the detergent chamber is less than the single dose amount, thereby preventing the laundry effect from being affected by insufficient detergent dose and preventing the liquid pump from running idle and affecting its service life.

[0085] (3) A water inlet valve is provided on the water channel plate, and a first solenoid valve and a second solenoid valve connected to the first water inlet and the second water inlet are provided in the water inlet valve, respectively. By providing a single water inlet valve, the two water channels can be controlled separately, which greatly improves the control efficiency of the water inlet and reduces the control cost of the water inlet.

[0086] The present invention is not limited to the above-mentioned optimal implementation mode. Anyone should be aware that any structural changes made under the inspiration of the present invention, and any technical solutions that are the same or similar to the present invention, fall within the scope of protection of the present invention.
