Below with reference to accompanying drawing, describe in detail according to drinking water treatment equipment of the present utility model.
As depicted in figs. 1 and 2, according to drinking water treatment equipment of the present utility model, comprising: RO film filter 10, preposition filtering unit 30, topping-up pump 20, pressure water storage barrel 40, pressure transmitter 50, magnetization filter element 80, the one or three two-port valve 70, the first normally closed valves 91 and controller (not shown)s.
Specifically, RO film filter 10 has water-in 11, tap water outlet 12 and rinse water outlet 13.Wherein, rinse water outlet 13 is connected with the first valve 61.
The output terminal of preposition filtering unit 30 is connected with the water-in 11 of RO film filter 10.
Topping-up pump 20 is located between the output terminal of preposition filtering unit 30 and the water-in 11 of RO film filter 10.
Pressure water storage barrel 40 is connected with tap water outlet 12 and pressure water storage barrel 40 has water outlet 41.Water outlet 41 is connected with second valve 62.
Magnetization filter element 80 is located between water outlet 41 and second valve 62, can make user obtain magnetization drinking water.
Pressure transmitter 50 is located in pressure water storage barrel 40 for detection of the pressure in pressure water storage barrel 40.
The one or three two-way, 70 have the first port 71, the second port 72 and the 3rd port 73.The first port 71 is connected with the input terminus of preposition filtering unit 30, and the second port 72 is connected with the output terminal of preposition filtering unit 30, and the 3rd port 73 is connected with rinse water outlet 13.
The first normally closed valve 91 is located between tap water outlet 12 and second valve 62.
Described controller is connected with the first normally closed valve 91 with the first valve 61, topping-up pump 20, second valve 62, the 50, the 1 two-port valve 70 of pressure transmitter respectively.
Simply introduce the working process according to drinking water treatment equipment of the present utility model below.
First, interior during without tap water when pressure water storage barrel 40, pressure water storage barrel 40 has the first predetermined pressure, and when the full tap water of the interior storage of pressure water storage barrel 40, pressure water storage barrel 40 has the second predetermined pressure.
Pressure in pressure transmitter 50 detects pressure water storage barrel 40 is between the first predetermined pressure and the second predetermined pressure time, the first port 71, the second port 72 and the 3rd port 73 that described controller is controlled three two-port valves 70 all disconnect, and described controller allows topping-up pump 20 to open when the first valve 61 conducting.
In other words, when water butt 40 interior storages drink the water yield between anhydrous state and full water state, when user uses water for cleaning, allow topping-up pump 20 to open so that RO film filter 10 carries out work.Thus, the tap water that RO film filter 10 can be made is stored in pressure water storage barrel 40, in order to user, uses.
When the pressure in pressure transmitter 50 detects pressure water storage barrel 40 equals the second predetermined pressure, described controller forbids that topping-up pump 20 opens when the first valve 61 conducting.Now, if the first valve 61 conductings, described controller is controlled the first port 71 disconnections of three two-port valves 70 and is controlled the second port 72 and the 3rd port 73 conductings of three two-port valves 70.
That is to say, when water butt 40 interior full water, by forbidding that the means that topping-up pump 20 is opened forbid 10 work of RO film filter.Now, the water for cleaning that user uses is through the pretreated water of preposition filtering unit 30.
When the pressure in pressure transmitter 50 detects pressure water storage barrel 40 equals the first predetermined pressure, described controller allows topping-up pump 20 to open when second valve 60 conducting.Now, if when user need to use tap water, described controller is controlled the second port 72 disconnections of three two-port valves 70 and is controlled the first port 71 and the 3rd port 73 conductings of three two-port valves 70, and the first normally closed valve 91 is opened simultaneously.
In other words, interior anhydrous when water butt 40, and user is need to use tap water time, by the means that allow topping-up pump 20 to open, is that 10 work of RO film filter are with instant potable water.Because pressure water storage barrel 40 has the first predetermined pressure under anhydrous state, therefore the first normally closed valve 91 is set and connects tap water outlet 12 and second valve 62.The water-in that rinse water enters in pre-process unit 30 again by RO film filter 10 carries out circulating filtration, to save water resources.
To sum up, according to user's water demand (use water for cleaning or use tap water) and according to the situation of the interior storage water yield of pressure water storage barrel 40 (anhydrous, full water or between anhydrous and full water), by switching pipeline, controlling the unlatching of topping-up pump 20 and control the means such as whether working of RO film filter 10, meeting under the prerequisite of user's water demand, avoid the water waste in water utilizing process, greatly saved water resources.
