[0003] The air humidity is high in coastal areas, especially on islands and fishing boats. In order to utilize the humidity in the air to produce water to solve the problem of shortage of fresh water resources, a Chinese utility model patent with patent number ZL 201420127441.3 (authorization announcement number CN 203782785U) discloses a device for obtaining direct drinking water from the air, including a dehumidification system, a water purification system and a heating system.

[0004] Although the device can utilize the condensed water formed by condensation of air moisture to obtain direct drinking water through deep purification, which can not only reduce air humidity but also allow residents in coastal areas with scarce fresh water resources, especially island residents, to obtain valuable direct drinking water, the device has the following limitations: in low temperature and low humidity conditions where sufficient water cannot be obtained from the air, it is necessary to utilize the reverse osmosis pump inside the device to filter and sterilize the external pressure-free water source through a PP cotton filter element, an activated carbon filter element, a first ultrafiltration membrane filter, and a first ultraviolet sterilizer in sequence before pumping it into the clean water tank to ensure that the device can be used normally under low temperature and low humidity conditions. Therefore, the above-mentioned device needs to provide an external water source when it is not under low temperature and low humidity conditions, thereby restricting the use of the drinking water equipment.

The air filter element 17 in this embodiment can be a composite filter element of non-woven fabric and activated carbon. The working process of the above-mentioned dehumidification system 1 can refer to the working principle of air conditioning.

[0027] In this embodiment, the second water tank 2 is connected to the first water tank 11 through the first pipe 31; the filter element assembly 4 is arranged on the first pipe 31, and the first pipe 31 is provided with a water pump 5 and a first control valve 61 for controlling the opening and closing of the first pipe 31. The first control valve 61 is a solenoid valve.

[0028] The output end of the second water tank 2 is connected to the fifth pipe 35, and the fifth pipe 35 is provided with a second control valve 62 for controlling the opening and closing of the fifth pipe 35. The outlet of the fifth pipe 35 corresponds to the normal temperature water outlet 1a. In addition, the output end of the second water tank 2 is connected to the third water tank 8 through the second pipe 32. The third water tank 8 is provided with a heating unit 91. The heating unit 91 in this embodiment is a heating pipe. The outlet of the third water tank 8 is connected to the third pipe 33. The third pipe 33 is provided with a third control valve 65 for controlling the opening and closing of the third pipe 33. The outlet of the third pipe 33 corresponds to the warm water outlet 1b. Figure 1 As shown, the third water tank 8 is arranged below the second water tank 2, and the bottom of the second water tank 2 is connected to the third water tank 8 through the second drain pipe 72, and a one-way valve 64 is arranged on the second drain pipe 72. The second control valve 62 and the third control valve 65 are both solenoid valves.

[0029] The output end of the second water tank 2 or / and the first water tank 11 is also connected to the first drain pipe 71. In this embodiment, the output ends of the second water tank 2 and the first water tank 11 are both connected to the first drain pipe 71. The first drain pipe 71 is provided with a drain valve 63. The outlet of the first drain pipe 71 corresponds to the drain port 1c. In addition, a sterilization module 92 is provided in the second water tank 2, the first pipe 31 and / or the third pipe 33. The sterilization module 92 in this embodiment can be an ultraviolet sterilization lamp.

[0030] In addition, the drinking water equipment also includes a first water level detection module for detecting at least two water levels of different heights in the first water tank 11 and a second water level detection module for detecting at least two water levels of different heights in the second water tank 2. In this embodiment, the first water level detection module and the second water level detection module are both liquid level floats. The liquid level float in the first water level detection module is used to detect three water levels, which are respectively recorded as low water level, middle water level and high water level.

[0031] The working process of the drinking water equipment in this embodiment is as follows:

[0032] 1. Condensate production process

[0033] When the liquid level float in the second water tank 2 detects that the water level is lower than the low water level, the dehumidification system 1 is started, and the blower 16 is also turned on, and the indoor air is continuously delivered to the air filter element 17, and then enters the condenser 13 through the air filter element 17. During the refrigeration process, the compressor 12 will first compress the refrigerant, and the compressed refrigerant will be liquefied, and a large amount of heat will be released at the same time, and the released heat will also be blown out by the wind blades to dissipate the heat; then the liquefied refrigerant will be transmitted to the evaporator 14, and the expansion valve 101 will release the pressure, the pressure will decrease, and the refrigerant will evaporate. A large amount of heat needs to be absorbed during the vaporization process, so the temperature of the evaporator 14 drops, and the wind blown out of the room will first pass through the evaporator 14, and the heat is absorbed, so the wind blown out is cold wind. At the same time, the indoor air meets the evaporator 14 and liquefies into water. At this time, the water will continuously flow into the first water tank 11. When it is detected that the water level in the first water tank 11 is greater than the middle water level, the first control valve 61 and the water pump 5 are opened to replenish water into the second water tank 2 until the liquid level float in the second water tank 2 detects the high water level and stops; if the water level in the first water tank 11 is lower than the low water level, then stop replenishing water into the second water tank 2;

[0034] 2. Condensate collection and stop process

[0035] When the liquid level float in the first water tank 11 detects a high water level, the dehumidification system 1 is shut down, and the blower 16 is also shut down;

[0036] 3. Heating process

[0037] When the liquid level float in the second water tank 2 detects the middle water level, the heating unit 91 is started until the temperature reaches the preset temperature. When the water temperature in the third water tank 8 is lower than the preset temperature due to the hot water being released, the heating unit 91 is started again until it reaches the preset temperature;

[0038] 4. Hydration process

[0039] When the liquid level float in the second water tank 2 detects a low water level, water replenishment is started, and at this time, the first control valve 61 and the water pump 5 are turned on until the liquid level float in the second water tank 2 detects a high water level;

[0040] 5. Emptying process

[0041] When the second control valve 62 and the third control valve 65 are not detected to be opened within the preset time, it is considered that no one is using them. In order to ensure the freshness of the water quality, the stored water in the system will be completely drained, that is, the drain valve 63 will be opened until the liquid level floats in the second water tank 2 and the first water tank 11 detect low water levels and stop.

[0042] Embodiment 2:

[0043] like Figure 2 As shown, different from the first embodiment, the output end of the second water tank 2 is connected to the fourth pipe 34, the fourth pipe 34 is provided with a heating body 93, and the outlet of the fourth pipe 34 corresponds to the warm water outlet 1b. The heating body 93 is an instant heater, and the heating of the instant heater is a prior art, which will not be elaborated here.

[0044] Different from the first embodiment, the drinking water equipment in this embodiment is an instant hot drinking water equipment, and the third water tank 8 in the first embodiment is not provided in the drinking water equipment.
