Abstract
The utility model discloses a reverse osmosis water purification machine with back pressure compensation. The reverse osmosis water purification machine comprises a water pump, a reverse osmosis filter and a pressure water storage tank and further comprises an MCU (Microprogrammed Control Unit) controller, a speed regulating switch and a pressure sensor, wherein the pressure sensor is arranged in the pressure water storage tank and is electrically connected to the output end of a main control board, and the speed regulating switch is connected to a working loop of a motor of the water pump in series. The reverse osmosis water purification machine has the advantages that the water yield is improved and the emission of waste water is lowered.
Description
Technical field
The utility model relates to a kind of household reverse osmosis water purifier, relates 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 after tested, the influence of barrel back pressure owing to be stressed, all there is the bigger problem of wastewater discharge in anti-penetration water purifier, 5:1 even higher waste water ratio may appear in actual use, when especially each water consumption was less, the waste water of generation was many more.
Summary of the invention
The purpose of this utility model is for providing a kind of reverse osmosis water purification machine with the back pressure compensation, and it can effectively solve the too much problem of discharge of wastewater.
For achieving the above object, the reverse osmosis water purification machine of band back pressure compensation of the present utility model 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 controller, speed control switch and pressure transmitter, described pressure transmitter is located in the pressure water storage barrel and is electrically connected to the output terminal of master control board, and described speed control switch is connected in the work loop of motor of water pump.
Described pressure water storage barrel comprises housing, is positioned at intravital water reservoir of shell and air bag, and described 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 controller by transmission signal, by a program that configures, send it back the type ripple and give speed control switch, come supercharging to advance film pressure with this by strengthening the water pump both end voltage, thereby improve water production rate, reduce wastewater discharge.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model patent is elaborated:
Fig. 1 is a circuit control synoptic diagram of the present utility model.
Among the figure:
The 100-MCU controller, 200-speed control switch, 300-pressure transmitter, 400-pressure water storage barrel, 401-air bag, 402-water pocket, 403-housing, 500-transformer, 600-motor.
Embodiment
The reverse osmosis water purification machine of band back pressure compensation of the present utility model 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, 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 are as shown in Figure 1, to increase MCU controller 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 being electrically connected the input terminus of MCU controller 100, speed control switch 200 then is electrically connected the motor 600 of 200 of the output terminal of MCU controller 100 and this speed control switchs and water pump and the transformer 500 formation work loop of connecting.
By above-mentioned improvement, when machine is started working, air bag 401 pressure sensors 300 are surveyed air bag 401 internal pressures, when having detected back pressure, can give MCU controller 100 by transmission signal, by a program that configures, send it back the type ripple and give speed control switch 200, come supercharging to advance film pressure with this by strengthening the water pump both end voltage, thereby improve water production rate, reduce wastewater discharge.
But above-mentioned embodiment is exemplary, is to understand and implement the utility model in order better to enable those skilled in the art to, and can not be interpreted as it is restriction to the utility model protection domain.So long as any being equal to of doing based on the spirit that the utility model disclosed changes or modification, all fall into protection domain of the present utility model.
