[0002] Existing coffee machines usually use a water tray to store waste liquid generated by making coffee and self-cleaning, and users need to dump the water tray frequently. For example, the Chinese utility model patent with patent number ZL202321335595.7 (authorization announcement number CN220069483U) discloses a water tray for a coffee machine, including a water tray, with a grille cover plate at the upper end, the grille of the grille cover plate includes transverse ribs and longitudinal ribs interwoven with the transverse ribs, and the upper end of the transverse ribs is inclined toward one side of the coffee machine. The angle α between the bottom of the previous transverse rib and the top of the rear transverse rib of adjacent transverse ribs and the horizontal plane is between 65° and 90°. The upper end of the water tray of the utility model adopts an inclined grille design to avoid direct observation of the interior, and the grilles block observations below 65 degrees, effectively avoiding the conventional observation angle of about 60 degrees; a liquid level reminder device is provided to effectively remind the internal water level height, which is convenient for timely dumping.

[0003] Although the waste liquid can be prevented from flowing everywhere by receiving the waste liquid in the water tray, the user needs to frequently empty and clean the water tray, which is troublesome to operate and affects the user experience. In addition, among the existing coffee machines and water purifiers, the coffee machine generally only has the function of dispensing coffee, while the water purifier generally only has the function of dispensing purified water.
