Description

A kind of reverse osmosis water purifier
Technical field
The utility model relates to a kind of water-purifying machine, and especially a kind of reverse osmosis water purifier belongs to the water treatment technology field.
Background technology
Understand according to the applicant, reverse osmosis water purifier is because characteristics and the technical limitation of reverse osmosis membrane (RO film) at present, when water-purifying machine is not worked, the RO film does not have pressure, osmosis can occur, and causes the material such as various ions to be permeated to the low part of concentration (water purification of corresponding water-purifying machine) by the high part of concentration (water inlet of corresponding water-purifying machine and condensed water).The user starts shooting when using water-purifying machine again, the materials such as the contained various ions of water purification of start initial stage (continue approximately tens seconds ~ tens seconds time) new system dense, the water-purifying machine that does not particularly have pressure pot (water tank), because do not have the higher water purification neutralization of other degree of purifications, thereby the water that causes not reaching desirable decontamination effect improving is used directly even drinks by the user.
The utility model content
The purpose of this utility model is: for the problem that above-mentioned prior art exists, propose a kind of reverse osmosis water purifier of the initial stage water quality that can guarantee to start shooting.
In order to reach above purpose, reverse osmosis water purifier of the present utility model comprises having water-in, pure water inlet, reverse osmosis membrane filt and the pilot circuit of condensed water outlet, the water-in of described reverse osmosis membrane filt is equipped with the suction culvert of the first magnetic valve, described pure water inlet connects water-supply line, described condensed water outlet is equipped with the discharge pipe of the second magnetic valve, be provided with current induction installation (pressure transmitter or flow sensor etc.) in the described water-supply line, the signal input port of the signal output part connection control circuit of described current induction installation, described water-supply line is connected to by the unidirectional branch road that leads to discharge pipe of the 3rd magnetic valve, and the control signal output terminal of described pilot circuit connects respectively first, the controlled end of the second and the 3rd magnetic valve.
Like this, when pilot circuit detects water-purifying machine for some time not water outlet, control is opened and is opened first, second, third magnetic valve, a certain amount of water purification and condensed water are all discharged by discharge pipe, so that the water purification that the high density water purification that produces because of infiltration is newly produced displacement, thereby remain the quality of the inner water purification of water-purifying machine, avoid the depuration quality at the initial stage of starting shooting to descend.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is the structural representation of the utility model embodiment one.
Embodiment
Embodiment one
The reverse osmosis water purifier basic structure of the present embodiment as shown in Figure 1, comprise have water-in, reverse osmosis membrane filt RO and the pilot circuit of the outlet of pure water inlet, condensed water, the water-in of reverse osmosis membrane filt is equipped with the suction culvert of the first magnetic valve D1, pure water inlet is connected the water-supply line of past water tap through the first check valve V1, the condensed water outlet is equipped with the discharge pipe of the 3rd magnetic valve D3.Fore filter F, the first flow sensor S1(or the pressure switch that have serial connection in the suction culvert) and be serially connected in the first magnetic valve D1 water pump B afterwards.Be provided with second quantity sensor S3, the post-filter F ' as the current induction installation of serial connection in the water-supply line, being provided with afterwards the third and fourth flow sensor S2(S2 at post-filter F ' is the TDS sensor---the total quantity sensor of Total Dissolved Solid dissolvable solid), S4, the signal input port of the signal output part connection control circuit of each sensor.Water-supply line also is connected to by the 3rd magnetic valve D3 and the unidirectional branch road that leads to discharge pipe of the second check valve V2.The control signal output terminal of pilot circuit connects respectively the controlled end of first, second, third magnetic valve D1, D2, D3.The second magnetic valve is other and meet waste water ratio divider I in the present embodiment.
Certainly, for increasing water flow, also pressure pot can be set in water-supply line.
Owing to having adopted above design, therefore being easy to realize following 2 kinds of controls:
The one, when pilot circuit detects water-purifying machine for some time when not working (when perhaps the TDS sensor S2 TSD that detects water purification is higher than a certain limit value), start corresponding water management processed---the work of water pump no power, the first and second flow sensors, the first and second magnetic valves all power on and are in normal operating conditions, the RO film relies on tap water hydraulic to drive, produce a small amount of water purification, water purification and condensed water are all discharged by discharge pipe, so that the water purification that the high density water purification that produces because of infiltration is newly produced displacement and being discharged, thereby improve the purification level of the inner water purification of water-purifying machine.Detect flow signal such as the 3rd flow sensor in the flushing process, illustrate that the user uses water-purifying machine, then flushing stops, and changes normal water process processed over to.The advantage of this scheme is: function is simple, noiselessness, and water displacement is few; Shortcoming is: during displacement because be that tap water hydraulic (common 0.2 ~ 0.4MP reverse osmosis water purifier) drives the RO film, the hydraulic pressure (approximately 0.6MP reverse osmosis water purifier) that water pump provides when being lower than normal operation, so it is more lower slightly than the purification level of normal water water purification processed (newly machine ratio of desalinization approximately 95%) that the water purification after the displacement in the machine purifies level (new engine ratio of desalinization approximately 85%), but can satisfy the demand of drinking.
The 2nd, when pilot circuit detects water-purifying machine for some time when not working (when perhaps the TDS sensor S2 TSD that detects water purification is higher than a certain limit value), startup is corresponding, and water management processed---water pump, the first and second flow sensors, the first and second magnetic valves all power on and are in normal operating conditions, the 3rd magnetic valve is opened simultaneously, and machine washes.The RO film relies on water pump that hydraulic drives is provided, produce more water purification, water purification and condensed water are all discharged from water shoot by pipeline, so that the water purification that the high density water purification that produces because of infiltration is newly produced displacement (flushing of RO film) and discharged machine, thereby improve the purification level of water-purifying machine inside water purification.Detect flow signal such as the 3rd flow sensor in the flushing process, flushing stops, and changes normal water process processed over to.The advantage of this scheme is: displacement is fast; The water purification of RO film can reach higher purification level (identical with the water purification of normal water generates processed) after the displacement; Shortcoming is that noise is larger.
In addition to the implementation, the utility model can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
