Abstract
Domestic straight water dispenser frequency conversion flow control system, including filter core, water calabash case, heating pipe and delivery port, the water -feeding pump is connected to the output of filter core, is equipped with the flowmeter for water pump output end, and the flowmeter output connects gradually water calabash case, heating pipe and delivery port, and CPU the control unit passes through circuit connection flowmeter and frequency conversion control system, and the frequency conversion control system passes through the circuit and is connected with the water -feeding pump. The utility model discloses a change the mains frequency control output water yield of water -feeding pump to realized that the water dispenser output water yield changes along with user desired output's temperature degree, solved the unstable and overflow phenomenon of appearance of rivers that the water pressure variation of system brought.
Description
Technical field
This utility model relates to water dispenser, is related specifically to the flow control system of water dispenser.
Background technology
Domestic direct drinking fountain provides the drinking water of different temperatures to improve conveniently to us at any time, although the domestic direct drinking fountain profile on market is various, but its internal process is mostly to filter link by clear water, utilize the drinkable water of electrothermal tube heating keypad instruction output different temperatures, this Structure and Process is in order to ensure to export water within the time flowing out electrothermal tube, water temperature rises rapidly to design temperature (such as 90 degree) it is necessary to limit water flow guarantee on request.
Typically, the water flow of domestic direct drinking fountain is by meeting minimum normal temperature water, meet and be heated to the requirement of maximum temperature and design, due to general high-power household electrical appliance all about 2KW (needing private jack higher than 2KW), therefore drinking water rises to 90 DEG C of flow velocitys per minute from 10 DEG C and is not higher than 350mL, this flow velocity is very slow, needs us to bear with.
Thus occurring in that out that water speed limits the output potential of water machine itself, such as, we have only to 50 DEG C of water or normal-temperature water, and 500mL water should quickly export for 1000mL/ minute only to be needed 30 seconds, but because above-mentioned reason presses 350mL/ minute output 90 second time of needs.
Even if being heated to 90 DEG C, the indoor temperature of the drinking water in winter and summer is different, such as summer 30 DEG C, its output flow also should relatively 10 DEG C of normal temperature water time flow velocity the most just to meet convention.
Simultaneously, in addition to independent pure water system (not having filter element filtering), due to external water pressure fluctuation (tap water) and the change of filter element filtering pressure reduction, General System pressure is the most unstable, so, all have employed the structural approach of " backwater current stabilization " with the domestic direct drinking fountain of defecator, it is ensured that defeated stable water outlet, being nature (gravity) water conservancy diversion due to take, also there is particular/special requirement position and structure to system " water receiver ".
Summary of the invention
The purpose of this utility model is to provide a kind of domestic direct drinking fountain, and it can be according to concrete temperature and pressure needs, and water flow is automatically adjusted, and reaches structure simplification, pressure stability, Quick water exit purpose.
For achieving the above object, the technical solution of the utility model is:
Domestic direct drinking fountain frequency conversion flow control system, including filter element, water calabash case, add heat pipe and outlet, it is characterized in that: the outfan of filter element connects feed pump, feed pump outfan is equipped with effusion meter, effusion meter outfan is sequentially connected with water calabash case, adds heat pipe and outlet, CPU control unit passes through circuit connection traffic meter and frequency-changing control system, and frequency-changing control system is connected with feed pump by circuit.
Advantage of the present utility model is: this device introduces motor variable-frequency speed-regulating control principle and combines the attribute specification of output water temperature degree and heating system, the output water yield is controlled by the supply frequency changing feed pump, it is achieved thereby that the water dispenser output water yield changes with the coolant-temperature gage of user's desired output, preferred temperature is low, require under premise meeting heating system, controlling frequency high, the output water yield is big.Otherwise, output is few.Control frequency it addition, changed by effusion meter feedback flow information, solve the system water pressure flow instability that brings of change and the overflow phenomena that occurs.
Accompanying drawing explanation
Fig. 1 is this utility model schematic diagram.
Detailed description of the invention
1 further illustrate detailed description of the invention of the present utility model below in conjunction with the accompanying drawings.
After this equipment power-on, user is by keyboard 16 selection storage water source mode: tap water 1 or bottled water 22, and only once, CPU control unit 19 meeting permanent memory is until change next time, explanation as a example by bottled water control flow below in this operation.
CPU control unit 19 is instructed when user inputs leaving water temperature by keyboard 16, such as require outlet temperature 90 DEG C, frequency-changing control system 15 is assigned relatively low output frequency instruction (the most about about 35Hz) by CPU control unit 19, make the speed operating that feed pump 6 is relatively low, water flow velocity is slower, effusion meter 7 feeds back flow signal to CPU control unit 19, CPU control unit 19 combines temperature detecting unit 11 and again frequency-changing control system 15 is finely tuned rate-adaptive pacemaker to feed pump 6, add heat pipe 9 because of the speed of current slower, it is ensured that the water temperature of outlet 10 meets setting demand.
In like manner, such as require outlet temperature 50 DEG C, frequency-changing control system 15 is assigned relatively low output frequency instruction (the most about about 45Hz) by CPU control unit 19, make the speed operating that feed pump 6 is higher, water flow velocity is very fast, effusion meter 7 feeds back flow signal to CPU control unit 19, CPU control unit 19 combines outlet temperature detection 11 and again frequency-changing control system 15 is finely tuned rate-adaptive pacemaker to feed pump 6, the most i.e. ensure that the water temperature of outlet 10, increase again the flow of outlet 10, shorten the time that user waits.
