Description

Technical Field

[0001] The present invention relates to the technical field of water purifiers, and in particular to an intelligent flushing and emptying system and a working method thereof. Background Art

[0002] Existing waterways usually have three major drawbacks:

[0003] First, when installing the filter for the first time and replacing the filter element later, you need to manually flush the filter element to ensure water safety and filter element life. Manual flushing is time-consuming and labor-intensive, and sometimes there will be problems with improper operation;

[0004] Second, when customers are on a long business trip or traveling, the water stored in the water machine is no longer fresh. Customers need to manually empty the machine after returning home to drink fresh water.

[0005] Third, when the water machine uses little water, the TDS display may occasionally be abnormal. At this time, if you empty the lower pressure tank, the TDS display will be normal. However, this operation requires on-site after-sales service, which will result in after-sales expenses. Summary of the invention

[0155] Further, as a preferred embodiment, after the water machine is installed, when the low-pressure switch is tripped, it enters a waiting state.

[0156]

[0157] Further, as a preferred embodiment, a first type of filter element flushing method including a heating type includes:

[0169] Furthermore, as a preferred embodiment, after replacing the second type of filter element and brushing the "NFC" anti-counterfeit filter element label, the water machine verifies the anti-counterfeit label with the IoT cloud based on its own signal strength. When the anti-counterfeit label verification is successful and the water machine detects that the low-pressure switch is in a closed state, it enters the flushing process. After the flushing process is completed, the emptying process is entered. After the pressure barrel is emptied, the first water production process is entered. After the pressure barrel is full of water, the emptying process is entered again. After the pressure barrel is emptied, the second water production process is entered.

If the power is cut off and restarted at this time, the prompt on the mobile phone will disappear, and the water machine will directly enter the flushing state.

[0171] Furthermore, as a preferred embodiment, when the water machine has no signal or the signal strength is weak and cannot connect to the cloud, it will first skip the cloud verification and enter the flushing process, and then perform anti-counterfeiting verification after the signal is connected to the network.

[0183] Furthermore, as a preferred embodiment, when the water machine has not been used for more than N days (that is, the interval between two executions of the first water production process and / or the second water production process is greater than N days, and the specific value of N is set according to actual needs), the emptying process is automatically triggered, and the water machine enters the pressure barrel emptying process and the cold water tank emptying process in sequence, and then enters the second water production process to produce water normally.

[0184] Furthermore, as a preferred embodiment, in an offline state, the water machine can also automatically trigger the emptying process according to its own state. The water machine sequentially enters the pressure barrel emptying process and the cold water tank emptying process, and then enters the second water production process to produce water normally.

[0185] Furthermore, as a preferred embodiment, when the water machine is full of water, the water machine detects and monitors the water quality in real time. When the water quality is poor, the water machine initiates an early warning prompt in the cloud background.

[0186] Furthermore, as a preferred embodiment, the technician sends an instruction to execute the emptying process to the water machine through the emptying button of the IoT cloud background to perform manual emptying.

[0187]

[0188] It should be noted that the specific duration of the above-mentioned first predetermined time period to the above-mentioned seventeenth predetermined time period is set according to actual needs. Since the sizes of pressure barrels or cold water tanks of different models are different, the specific flushing and / or emptying time needs to be set according to actual needs.
