Abstract
The invention discloses a reverse osmosis pure-water machine with back pressure compensation. The reverse osmosis pure-water machine comprises a water pump, a reverse osmosis filter, a pressure water storage drum, a microprogrammed control unit (MCU) controller, a speed regulating switch and a pressure sensor, wherein the pressure sensor is arranged in the pressure water storage drum and is electrically connected to the output end of a master control board; and the speed regulating switch is connected to the work loop of the electric motor of the water pump in series. The reverse osmosis pure-water machine has the advantages of improving the water yield and reducing the waste water emission load.
Description
Technical field
The present invention relates to a kind of household reverse osmosis water purifier, relate in particular to a kind of reverse osmosis water purification machine with the back pressure compensation.
Background technology
At present, common household reverse osmosis water purifier 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 reverse osmosis water purification machine of this band pressure water storage barrel 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 even higher waste water ratio in actual use, 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 that a kind of reverse osmosis water purification machine with the back pressure compensation is provided, and it can effectively solve the too much problem of discharge of wastewater.
For realizing above-mentioned purpose, the reverse osmosis water purification machine of band back pressure compensation of the present invention adopts following technical scheme:
A kind of reverse osmosis water purification machine with the back pressure compensation; Comprise water pump; Reverse osmosis filter, pressure water storage barrel; It is characterized in that: also include MCU unit, speed control switch and pressure transmitter, said pressure transmitter is located in the pressure water storage barrel and is electrically connected to the output terminal of master control board, and said speed control switch is connected in the work loop of motor of water pump.
Said pressure water storage barrel comprises housing, is positioned at intravital water reservoir of shell and air bag, and said pressure transmitter is located in the air bag.
Adopt said structure, when machine is started working, intracapsular pressure transmitter probe gas intraluminal pressure; When having detected back pressure, can give the MCU unit by transmission signal, through a program that configures; Send it back the type ripple and give speed control switch; Come supercharging to advance film pressure with this through strengthening the water pump voltage, thereby improve water production rate, reduce wastewater discharge.

Description of drawings
Below in conjunction with accompanying drawing and embodiment patent of the present invention is elaborated:
Fig. 1 is a circuit control synoptic diagram of the present invention.
Among the figure:
The 100-MCU unit, 200-speed control switch, 300-pressure transmitter, 400-pressure water storage barrel, 401-air bag, 402-water pocket, 403-housing, 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 and pressure transmitter 300.Pressure transmitter 300 is arranged in the air bag 401 of pressure water storage barrel 400; And be electrically connected the input terminus of MCU unit 100,200 of output terminal and this speed control switchs that speed control switch 200 then the is electrically connected MCU unit 100 formation work loop of connecting with the motor 600 of water pump and X-former 500.
Through above-mentioned improvement, when machine was started working, air bag 401 pressure sensors 300 were surveyed air bag 401 internal pressures; When having detected back pressure, can give MCU unit 100 by transmission signal, through a program that configures; Send it back the type ripple and give speed control switch 200; Come supercharging to advance film pressure with this through strengthening the water pump voltage, thereby improve water production rate, reduce wastewater discharge.
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.
