In the case of user's low water usage amount, the power-off of main feed water pump 12 in non-negative pressure method of water supply module 100 is stopped, at this time, the second electricity
Control valve to open, the first water pump 22 is powered operating, and the water that main water inlet tube 11 exports after 22 pressurized treatments of the first water pump by passing through by the
Two bypass pipes 302 are delivered to primary flow pipe 13, so as to meet water supply requirement of the user in the case of low water usage amount.And on
The size of family water consumption, can be monitored by flow monitoring equipment, when user's life water consumption is few, preferentially open first
Water pump 22 supplies water, and when 22 water supply of the first water pump can not meet user demand, main feed water pump 12 is then turned on, so as to play
Energy-conserving action.
Further, for the waste water for sufficiently utilizing direct drinking processing module 200 to produce, the feedwater of the present embodiment sub-prime
Equipment further includes concentrated water collecting box 401 and washes away water collection tank 402, and the waste water discharge opening connection of the filter membrane component 32 is described dense
Water collection tank 401, and water collection tank 402 is washed away in the connection of the backwashing water outlet of pre-filtering component 21, cartridge filter 22.Tool
Body, during the water process for conveying city planting ductwork forms direct drinking, the water of city planting ductwork conveying passes through pre-filtering group
Water after 22 filtration treatment of part 21 and cartridge filter is entered in filter membrane component 32, and enters the part in filter membrane component 32
Water forms direct drinking and is delivered in clear water tanks 33, is trapped within the ion of the influent side of film, organic matter, bacterium, virus etc. with surplus
Remaining water forms concentrated water and from the waste water discharge opening of filter membrane component 32, the waste water that concentrated water collecting box 401 is collected only be water hardness,
Turbidity is higher to be unsatisfactory for user's domestic water, still, due to being conducive to plant growth containing organic matter and inorganic salts in concentrated water, leads to
Overrich water collection tank 401 collects the irrigation that concentrated water can be used for cell plant；And for pre-filtering component 21, cartridge filter 22
Carry out backwashing caused backwashing water, due to exceeded containing medicament, pH value, it is impossible to be used in the irrigation of plant, can pass through
Wash away water collection tank 402 to be collected, the water washed away in water collection tank 402 can be used for washing away for public restroom in cell
Water.Potable water equipment in compared with the prior art can maximize the directly outer row of waste water, the present embodiment sub-prime water work
Utilization water resource, reduce waste, realize environmentally protective.
The utility model also provides a kind of method of supplying water of above-mentioned sub-prime water work, including water quality adjustment water supply pattern；
The water quality adjustment water supply pattern：When the water quality of the second water quality sensor detection is not up to standard, primary flow pipe output
Water first pass through after pre-filtering component carries out filtration treatment, then passed through after being pressurizeed by the first water pump and master be delivered to by the first bypass pipe
Outlet pipe.Specifically, the water in city planting ductwork is influenced by factors such as season, environment, different times, the water quality in city planting ductwork
Can be different, after the deteriorating water quality of city planting ductwork, this will cause the deteriorating water quality of the domestic water of user, in order to ensure user gives birth to
Quality of water living keeps higher level, to improve user experience, to user for domestic water during, in the second water
When the water quality of matter sensor detection is not up to standard, then the part water of primary flow pipe output is by by the pre- mistake in direct drinking processing module
Component processing is filtered, so that the water source of higher water quality is obtained, then, then it is by the first bypass pipe that the water of the high water quality after processing is defeated
Sending to primary flow pipe, so can effectively adjust the water quality of user's domestic water, so that the feedwater of the present embodiment sub-prime is set
Standby functional diversities, versatility are stronger.Wherein, water quality adjustment water supply pattern, is specially：When the detection of the second water quality sensor
When water impurity is exceeded, the water of primary flow pipe output passes through more medium filter filtration treatment；And/or when the second water quality sensor
The water of detection have peculiar smell it is heterochromatic when, primary flow pipe output water pass through active carbon filter filtration treatment.
Further, the method for supplying water further includes energy saving water supply pattern, the energy saving water supply pattern, when user terminal is always used
When water is less than setting value, main feed water pump shuts down, and the water that main water inlet tube introduces is delivered to the first water via the second bypass pipe
Pump, then passed through after being pressurizeed by the first water pump and primary flow pipe is delivered to by the first bypass pipe.Specifically, transported in non-negative pressure method of water supply module
During row, for main feed water pump in order to provide sufficiently large hydraulic pressure, the power of main feed water pump is larger to cause power consumption larger, still,
In the stage at night, the water consumption of user is seldom, and at this time, energy saving water supply pattern starts, and main feed water pump shuts down, and utilizes straight drink
The water pressurized delivered that the first water pump in water treating module is introduced main water inlet tube as power is to user terminal, in this way, can be
In the case that water consumption is less, the energy consumption of the present embodiment sub-prime water work is effectively reduced, realizes that green low-carbon is run.
The method of supplying water of sub-prime water work provided by the utility model, is at the same time use by using non-negative pressure method of water supply module
The domestic water and direct drinking processing module at family supply water, without non-negative pressure method of water supply mould is separately configured for direct drinking function
Block, this will greatly reduce installation cost and use cost, while the occupied space of complete equipment is substantially reduced, meanwhile,
The water quality situation of the water of non-negative pressure method of water supply module conveying is detected using the second water quality sensor in main waterway, when detecting water
When matter is unsatisfactory for requiring, part water can be again returned to primary flow pipe output after the processing of pre-filtering component, so as to
The convenient water quality for adjusting user's domestic water, realizes sub-prime water work function diversification, and reduces the space shared by it,
Reduce cost of installation and use.
Finally it should be noted that：Above example is only to illustrate the technical solution of the utility model, rather than its limitations；
Although the utility model is described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that：
It can still modify the technical solution described in foregoing embodiments, or which part technical characteristic is carried out etc.
With replacement；And these modifications or replacement, the essence of appropriate technical solution is departed from various embodiments of the utility model technology
The spirit and scope of scheme.
