Problems solved by technology

[0005] Due to its own needs, the direct drinking machine purifies the municipal tap water into drinking water that can be directly drunk. The tap water is mixed with tap water, and the water is produced again. Therefore, there are very high requirements for the control of the raw water quality. If the water quality of the raw water exceeds a certain index, it is impossible to prepare drinking water that can be directly consumed. The above two water purification devices All have a method of detecting water quality through TDS sensors, but because the detection method is too simple, it only directly judges whether it is suitable after detecting the water quality of raw water, without any analysis process, resulting in inaccurate overall detection and prone to errors. Judging the situation, so the current direct drinking machine has a certain room for improvement

Embodiment 1

[0058] Embodiment 1, a disclosed raw water control system based on a direct drinking machine, such as figure 1 As shown, the current direct drinking machine includes a raw water tank 1 for raw water storage, and the raw water in the raw water tank 1 is sequentially transmitted to the melt-blown fiber filter element 4 and the granular activated carbon filter element through the water inlet solenoid valve 2 and the booster pump 3 5 and the compressed activated carbon filter element 6, the waste water is circulated to the raw water tank 1 after the cationic resin filter element 8 is passed through the reverse osmosis membrane 7, and the purified water is transmitted to the clean water tank 10 through the sintered activated carbon filter element 9 for people to use. water, the clean water is heated by the heating device 11 and stored in the hot water tank 12, the heating device 11 is preferably a thermal relay or an electric heating wire; if cold water is needed, the clean water is...

Embodiment 2

[0075] Embodiment 2, a control method, including the above-mentioned raw water control system based on a direct drinking machine, such as image 3 As shown, the specific control method is as follows:

[0076] Step 1. Position the working time of the booster water pump 3 as T1, and the TDS sensor detects the raw water every interval of T1 and records the water quality data as S1;

[0077] Step 2. Judging the water quality data S1 sequentially, whether the water quality data S1 is greater than or equal to P times the memory reference value V; if the water quality data S1 is greater than or equal to P times the memory reference value V, then execute the next step; otherwise, enter the stable mode ;

[0078] Step 3. Define the interval time T2. The TDS sensor detects the raw water every T2 and records the water quality data as S2;

[0079] Step 4, perform step 3 M times continuously;

[0080] Step 5. Judging the M water quality data S2, and judging whether any water quality dat...

Abstract

The invention discloses a raw water control system based on a direct drinking machine and a control method thereof. The problem that a raw water quality detection method is simple and prone to misjudgment is solved. According to the technical scheme, if water quality data S1 are P times greater than a memory reference value V, a control module controls a TDS detection module to carry out a couple of times of successive detection to acquire water quality data S2, and the water quality data S2 are stored into a storage module; the control module calls the water quality data S2 in the storage module and sequentially compares the water quality data S2 with the memory reference value V; and if the water quality data S2 are P times greater than the memory reference value V, the control module controls an alarm module to start to enter an alarm mode, otherwise a standby mode is started. According to the invention, the water quality in a raw water tank is reasonably detected; a user can acquire standard drinking water in a use process; if the raw water quality is wrong, an alarm is given to remind the user; and the maintenance of the user is convenient.

Description

technical field [0001] The invention relates to a straight drinking machine, in particular to a raw water control system and a control method based on a straight drinking machine. Background technique [0002] A direct drinking machine is an appliance that can purify municipal tap water into direct drinking water, or at the same time heat, cool and distribute the purified water by consuming electric energy. [0003] The notification number is CN104310613B, which discloses a water-saving water purification device, which is mainly composed of a filter element connected by a pipeline, a reverse osmosis membrane filter element, and a data acquisition and intelligent analysis system. The raw water pipeline is equipped with a raw water TDS detection sensor. The water purification pipeline of the osmotic membrane filter element is connected with a water storage tank, and the water storage tank or the water purification pipeline is provided with a water temperature sensor and a pure...
