Abstract
The invention relates to a water-saving method of a reverse osmosis water purification machine which comprises a reverse osmosis filter, a water pump connected with a water inlet of the reverse osmosis filter, and a pressure water storage tank connected with a purified water outlet of the reverse osmosis filter. The water-saving reverse osmosis water purification machine further comprises an MCU controller and a speed control switch, wherein a timer is arranged on the MCU controller, and the speed control switch is electrically connected with an output terminal of the MCU controller and connected in series in a working circuit of a motor of the water pump. When the machine starts to work, the MCU controller starts to time till the pressure water storage tank is filled with water, the high pressure switch takes off, and the total time is recorded as a T value. The T value is equally divided into N parts, in each T/N time, the MCU controller increases the water pump power through the speed control switch, thereby increasing a water inlet pressure P value. The water-saving reverse osmosis water purification machine effectively solves the problem of excessive discharge of waste water and is advantageous in water saving.
Description
Technical field
The present invention relates to a kind of household reverse osmosis direct drinking fountain, relate in particular to reverse osmosis water purification machine.
Background technology
At present, common household reverse osmosis direct drinking fountain on the market, its reverse osmosis filter pure water outlet connects a threeway, and threeway is connected with pressure water storage barrel and post-filter respectively at two ends in addition, and the water side of post-filter is connected with depotition cock again.The machine of this band bucket is found through test; The influence of barrel back pressure owing to be stressed, all there is the bigger problem of wastewater discharge in anti-penetration water purifier, possibly occur 5: 1 in actual use even higher waste water ratio; When especially each water consumption was less, the waste water of generation was many more.
Summary of the invention
The object of the invention is the water-saving method that a kind of reverse osmosis water purification machine is provided, and it can effectively solve the too much problem of discharge of wastewater.
For realizing above-mentioned purpose, the water-saving method of reverse osmosis water purification machine of the present invention adopts following technical scheme:
Reverse osmosis water purification machine comprises reverse osmosis filter; Connect the water pump of reverse osmosis filter water-in and the pressure water storage barrel that connects the outlet of reverse osmosis filter pure water; Also include MCU unit, speed control switch; Have timing register on the said MCU unit, said speed control switch is electrically connected the parallel-series of MCU controller output end in the work loop of the motor of water pump, it is characterized in that:
When machine was started working, MCU unit internal timer picked up counting, and is full to pressure water storage barrel water, the high-voltage switch gear take-off, and record total time is the T value;
The T value is equally divided into the N equal portions, the time of every T/N, increases intake pressure P value thereby the MCU unit increases water pump horsepower through the adjustment speed control switch.
In addition, reverse osmosis water purification machine also increases has high-voltage switch gear, and said high-voltage switch gear is installed between outlet of reverse osmosis filter pure water and the pressure water storage barrel and is electrically connected the input terminus of MCU unit.
Adopt said structure, when machine was started working, MCU unit internal timer picked up counting, and is full to pressure water storage barrel water, the high-voltage switch gear take-off, and record total time is T value (do not installing under the high-voltage switch gear situation, this total time can be set according to test is artificial).The T value is equally divided into the N equal portions, sets the time of every T/N in the program, thereby increase water pump horsepower increase intake pressure P value (the P value can be definite value, also can be underrange) at present through the adjustment speed control switch.Thereby remedy because the water production rate that the pressure water storage barrel back pressure causes is little wastewater flow rate discharging problem in the past.
Description of drawings
Below in conjunction with accompanying drawing and embodiment patent of the present invention is elaborated:
Fig. 1 is the circuit control synoptic diagram of reverse osmosis water purification machine of the present invention.
Among the figure:
The 100-MCU unit, 200-speed control switch, 300-high-voltage switch gear, 500-X-former, 600-motor.
Embodiment
The reverse osmosis water purification machine of band back pressure compensation of the present invention is the improvement on existing reverse osmosis water purification machine basis; Existing reverse osmosis water purification machine comprises pretreatment filters, the water pump of serial connection successively; Reverse osmosis filter; The outlet of reverse osmosis filter pure water connects a threeway, and threeway is connected with pressure water storage barrel and post-filter respectively at two ends in addition, and the water side of post-filter is connected with depotition cock again.
Its improvements do, and are as shown in Figure 1, increase MCU unit 100, speed control switch 200, high-voltage switch gear 300.Has timing register in the MCU unit 100.200 of output terminal and this speed control switchs that speed control switch 200 the is electrically connected MCU units 100 formation work loop of connecting with the motor 600 of water pump and X-former 500.High-voltage switch gear 300 is installed between outlet of reverse osmosis filter pure water and the pressure water storage barrel and is electrically connected the input terminus of MCU unit 100.
Through above-mentioned improvement, MCU unit internal timer picks up counting, and is full to pressure water storage barrel water, high-voltage switch gear 300 take-offs, and record total time is the T value.The T value is equally divided into the N equal portions, sets the time of every T/N in the program, thereby increase water pump horsepower increase intake pressure P value (the P value can be definite value, also can be underrange) at present through adjustment speed control switch 200.Thereby remedy because the water production rate that the pressure water storage barrel back pressure causes is little wastewater flow rate discharging problem in the past.
During practical implementation, machine begins to start to water for the first time expires, and does not carry out the back pressure compensation, only total system water time of record.From beginning according to segmentation for the second time, carry out pressure compensation.
Therefore, the present invention effectively solves the too much problem of discharge of wastewater, has the advantage of water saving.
But above-mentioned embodiment is exemplary, is to understand and embodiment of the present invention in order better to enable those skilled in the art to, and can not be interpreted as it is the restriction to protection domain of the present invention.So long as any being equal to of doing based on disclosed spirit changes or modification, all fall into protection scope of the present invention.
