[0038] The accompanying drawings are for illustrative purposes only and should not be construed as limiting the scope of this patent. To better illustrate this embodiment, some parts in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product.
[0039] It will be understood by those skilled in the art that certain well-known structures and their descriptions may be omitted in the accompanying drawings. The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.
[0040] like Figures 1-4 As shown, this utility model provides a direct drinking water machine with a self-cleaning function and a water tray 112. Its main structure includes a body 1, with a water outlet 12 on the body 1 and a water collection box 11 below the water outlet 12. An overflow groove 111 facing the center of the water collection box 11 is formed on the side of the water collection box 11, and a water tray 112 is arranged inside the water collection box 11. A water storage space 113 is formed between the water collection box 11 and the water tray 112. A drain sleeve 1122 is arranged at the center of the water tray 112, and a filter screen 114 is detachably connected to one end of the drain sleeve 1122. Multiple water-permeable strip holes 1121 are formed on the water tray 112.
[0041] The unit 1 contains a water purification assembly for filtering water, which includes a pre-filter 21, a booster pump 22, and a filter membrane 23 connected in sequence. The filter membrane 23 has a pure water outlet 231 and a concentrated water outlet 232. The pure water outlet 231 is used to output purified drinking water, and the concentrated water outlet 232 is connected to a concentrated water collection tank 24 via a pipeline. A collection control valve 233 is installed on the pipeline between the concentrated water outlet 232 and the concentrated water collection tank 24. The concentrated water collection tank 24 is connected to the overflow trough 111 on the side of the water collection box 11 via a pipeline, and a flushing control valve 241 is installed on this connecting pipeline.
[0042] The inner bottom wall of the water collection box 11 has a first drain hole 115 and a second drain hole 116. An extension pipe 1151 is connected to the upper end of the first drain hole 115. The inner diameter of the extension pipe 1151 is slightly larger than the outer diameter of the drain sleeve 1122, allowing the drain sleeve 1122 to be inserted into it. A filter screen 1152 can be installed inside the extension pipe 1151 to filter impurities in the flushing water. The second drain hole 116 is connected to a wastewater discharge valve 1161 for discharging wastewater from the water collection box 11 when needed.
[0043] The volume of the concentrate collection tank 24 can be set to 2L, and the vertical distance between the concentrate collection tank 24 and the water receiving tray 112 is 0.4m. This setting ensures sufficient water volume and a certain water flow impact force during each flush. To better control the flushing process, a liquid level sensor 242 can be installed inside the concentrate collection tank 24. When the concentrate reaches the preset water level, the collection control valve 233 can be automatically closed. A support plate 117 can also be installed inside the water collection box 11 to stably support the water receiving tray 112. In addition, the concentrate outlet 232 can be connected to an independent discharge pipeline equipped with a concentrate discharge valve 235, which allows the concentrate to be discharged directly when flushing is not required.
[0044] A control microcontroller 3 is installed inside the body 1. The control microcontroller 3 is electrically connected to the liquid level sensor 242, the concentrated water discharge valve 235, the collection control valve 233, the flushing control valve 241, and the wastewater discharge valve 1161 via a wired connection. It can automatically control each control valve to open or close according to the set program.
[0045] After the concentrated water is collected, the microcontroller 3 controls the cleaning process of the water receiving tray 112 at a set time. The rinsing time can be set through the control module. The default rinsing frequency is once every night to prevent tea leaves and other waste generated during the day from drying and sticking to the surface of the water receiving tray 112, making it difficult to clean.
[0046] The specific cleaning process is as follows:
[0047] When the concentrated water collection is complete and rinsing is required, the control module controls the flushing solenoid valve of the water receiving tray 112 to open. At this time, the concentrated water collected in the concentrated water collection tank 24 flows to the water collection box 11 by gravity through the flushing solenoid valve of the water receiving tray 112. In order to ensure that the flushing concentrated water has a certain flow rate, the concentrated water collection tank 24 needs to maintain a certain height difference with the water receiving tray 112; at the same time, in order to prevent the water from overflowing due to excessive flow rate and the limited internal space of the water purifier, the height difference between the concentrated water collection tank 24 and the water receiving tray 112 should not be too large. After calculation and experimentation, a height of 0.4m between the concentrated water collection tank 24 and the water receiving tray 112 is more suitable.
[0048] Then, after the concentrated water flows into the overflow tank 111, it will flow outwards towards the water receiving tray 112 as the water level rises. The concentrated water flows into the water storage space 113 through the permeable strip holes 1121 on the water receiving tray 112. At this time, the wastewater discharge valve 1161 is in the closed state, so the water level in the water storage space 113 gradually rises until it submerges the water receiving tray 112. Residues on the water receiving tray 112, such as tea leaves, are more easily washed into the drain sleeve 112 by the water flowing out of the overflow tank 111 due to the buoyancy of the water. After being filtered by the filter screen 114, the residues are collected. Finally, the wastewater discharge valve 1161 is opened to discharge the wastewater in the water storage space 113.
[0049] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here.
