Abstract
The utility model provides a solar water heater with a micro-artesian vacuum tube that pushes out hot water by pressing inlet cold water. The utility model consists of a small water container and a vacuum tube solar energy collector that are arranged in the sun outdoors and a large water container indoors arranged above the small one. On the larger water container is arranged a pressure switch to detect the water pressure inside with the bottom of the pressure switch connected with a tap water pipe by an electromagnetic valve. The power switch of the coil of the electromagnetic valve functions as the pressure switch. As the hot water switch is off and the electromagnetic valve is on, the water pressure becomes higher and higher. When the water pressure reaches above the disconnection set point, the pressure switch is cut off automatically and the electromagnetic valve is out of power and cut off. When hot water switch is turned on and electromagnetic valve is turned off, the water pressure becomes lower and lower. When the water pressure reaches below the connection set point, the pressure switch is turned on automatically and the electromagnetic valve is turned on, hot water is pushed out by cold water.
Description
Affiliated technical field
The utility model relates to a kind of little pressure type vacuum tube solar water heater that is ejected the hot water effluent by pressure cold water (running water) water inlet.
Background technology
At present, known solar vacuum-tube water heater divides non-bearing type and pressure-bearing type two classes.Non-bearing type is generally adopt at present a kind of, and it utilizes height water-head between storage tank and the hot water water consumption device to produce pressure and makes the hot water outflow.Its storage tank and a vacuum pumping pipe thermal-collecting tube that directly inserts it just must be placed on highest point, that the restriction of this installation site just can not be made is split type (as balcony wall-hanging etc.), the scope of application is very restricted.Storage tank also must have a return-air hole, has influenced its heat insulation effect.In addition, the hot water outflow pressure is little, and cleaning action is not strong, and is especially then poorer in the little occasion of drop, also will carry out the moisturizing of automatic or manual.Because storage tank is to the water consumption device distance, pipeline is long and have greatly outdoor, and heat radiation is many and easily freeze, and will bleed off more cold water before hot water flows out.The vacuum tube thermal-collecting tube is placed on eminence (on the roof), generally can not clean.Superincumbent dust etc. reduces the thermal efficiency with regard to influencing solar light irradiation like this.Pressure type vacuum tube solar water heater can overcome these defectives of non-bearing type, and generally it remains with pressure cold water source (running water) and communicates, but whole system will be born big pressure (2-3kgf/cm when hot water outlet is closed
2), and be that this just requires it that good material and technology is arranged for a long time.Wherein more scabrous is the junction of vacuum heat collection pipe and it and storage tank.So present pressure type vacuum tube solar water heater mostly adopts following method, promptly in vacuum tube, absorb heat and again heat is passed to water in the storage tank by other solid or liquid.Solar energy is not directly passed to and is answered water, and it is high and cost is high to adopt the thermal efficiency, so be not extensive use.
Summary of the invention
High and adopt low these two problems of the thermal efficiency for the cost that solves pressure type vacuum tube solar water heater, the utility model provides a kind of little pressure type vacuum tube solar water heater.Material, technology that it requires are suitable with the non-bearing type solar vacuum-tube water heater, so cost is also the same substantially, but have the advantage of pressure-bearing type.Because it only bears about 0.3kgf/cm
2About so little pressure, and water still can be at vacuum heat collection pipe Nei Caire, so the height of thermal efficiency ratio pressure-bearing type.
The technical scheme that its technical problem that solves the utility model adopts is: a little storage tank and the direct row's solar vacuum heat-collecting pipe that inserts it have been placed on sunlit place, as hang on the balcony outer wall; The big storage tank higher than storage tank position is placed on indoor (as hanging on the interior wall of balcony), pressure switch is housed in order to survey its inner hydraulic pressure (can be contained on the cold water inlet line that leads directly to it) on it; Large and small storage tank is linked to each other to carry out the exchange naturally of hot and cold water by two water pipes, and wherein one connects two storage tank bottoms, and another root is linked little storage tank top from the middle part of big storage tank, form hot and cold water and exchange two passages that separate naturally; Cooling water inlet and hot water outlet are placed in the bottom and the top of big storage tank respectively, and cooling water inlet is connected to the pressure tap water pipe line by Cold water tap, and this Cold water tap is a magnetic valve, and the power switch of its coil is exactly a pressure switch of surveying hydraulic pressure.The principle of control is: when hot-water valve close and electromagnetic valve when opening the hydraulic pressure in the big storage tank will progressively raise, pressure switch disconnects when the disconnection setting value of hydraulic pressure overpressure switch, magnetic valve dead electricity and closing; When hot-water valve open and during closed electromagnetic valve the hydraulic pressure in the big storage tank will progressively reduce, to the connection setting value that is lower than pressure switch, pressure switch is connected, magnetic valve gets electric and opens, and forms cold water top hot water effluent's state.This state is called the dynamical state of water heater.The setting value that pressure switch disconnects is greater than the setting value of connection, and a switch return difference is promptly arranged.This switch return difference is meant that the pressure of control closed electromagnetic valve deducts the pressure that the control magnetic valve is opened.It is the frequent switch motion of magnetic valve that the setting of switch return difference can also be avoided because of the hydraulic pressure shakiness causes Cold water tap.If the hydraulic pressure of pressure switch detection place is the dynamic pressure of water heater during the dynamical state of water heater, generally this dynamic pressure has only 0.2kgf/cm
2About.Adjust the pressure switch parameter to following state: the hydraulic pressure of pressure switch detection place is greater than the dynamic pressure of water heater, as greater than 0.3kgf/cm
2Pressure switch disconnects, and the magnetic valve dead electricity is closed; The hydraulic pressure at pressure detector place is equal to or less than 0.2kgf/cm
2Pressure switch is connected, and magnetic valve gets electric opening.The switch return difference that it here is set is 0.1kgf/cm
2Because the water heater dynamic pressure has only 0.2kgf/cm
2About, so little pressure type vacuum tube solar water heater that the utility model provides only bears 0.3kgf/cm
2About pressure, and duty and present pressure-bearing type is just the same.Be full closeding state when not using hot water, hydro-thermal expands and can increase the interior pressure of water-heater system, and the overflow pressure-reducing valve can be installed.The protective device of its system during simultaneously also as a valve invalidation.
The beneficial effects of the utility model are that the solar vacuum-tube water heater made from material, technology and the cost of non-bearing type solar vacuum-tube water heater reaches the same effect of pressure type vacuum tube solar water heater and adopts thermal efficiency height.
