Abstract
The utility model relates to a solar water heater with an emptying pipe. The solar water heater with an emptying pipe comprises a water storage tank, a control valve, and a water supply and discharge pipeline communicated with the water storage tank through the control valve. One air guiding pipe is arranged on the water storage tank. The solar water heater with an emptying pipe has the advantages of simple structure and convenient utilization. In addition, the problems of water pipe residual water and water pipe frosting and block in winter can be thoroughly solved.
Description
The utility model relates to solar water heater, relates in particular to the solar water heater with emptied of water pipe unit.
Solar water heater makes full use of solar energy with it and free of contamination significant advantage has entered huge numbers of families, is subjected to users' popular welcome.Be connected with two pipelines on the water storage tank of common in the market solar water heater, one is used for to water storage tank feed cold water or from the drainage pipeline of water storage tank discharging hot water; Another root then only is used to indicate the overflow pipe of the feed water yield.Overflow pipe is in the emptying state at ordinary times, and drainage pipeline then is in forever water state, and this freezes stifled bursting by freezing problem winter with regard to pipeline cold water and pipeline having occurred.At first, for the user of skyscraper, each water all will discharge earlier and be dissolved in this ducted cold water, can use hot water, and the floor difference that the user occupied is big more, the cold water of each discharging is just many more, form great water resource waste, reduce rate of thermal water utilization, also make troubles to the user; Secondly, in the winter time, when temperature is reduced to below 0 ℃, be frozen to ice for the cold water in the discharge pipe, the vent pathway of the stifled hot water that broken can't be used water heater, and even more serious is when there's a sudden fall in temperature, also can cause the freezing bursting by freezing of pipeline.
Chinese patent (patent No. 982279892) specification discloses a kind of freezing prevention tubing formula solar water heater, and it is to have increased control valve and automatic two electrically operated valves of emptying valve on the drainage pipeline at water storage tank lower part outlet place.Close automatic exhaust-valve and open control valve, can discharge hot water, subsequently, closed control valve and open automatic exhaust-valve, the hot water in the emptying drainage pipeline makes pipeline be in emptying state, to avoid freezing and bursting by freezing of drainage pipeline; When water storage tank feed cold water, then close automatic exhaust-valve again and open control valve.This structure has not only adopted the valve of two need interoperations, and it is comparatively complicated that structure becomes, and increased product cost and fault rate; And must close, open respective valves when using successively, and water supply and sewage smoothly, using to the user has increased trouble; Adopt this structure in addition, supply water and to make reverse flow through control valve, affect water supply speed to cistern.
It is simpler that the purpose of this utility model provides a kind of structure, uses water pipe emptying type solar water heater more easily, and it can not only be automatically with the drainage pipeline emptying, and more smooth rapidly to water storage tank feed water.
In order to achieve the above object, the utility model provides a kind of water pipe emptying type solar water heater, this water heater comprises water storage tank, control valve and water supply and sewage pipe, the water supply and sewage pipe is connected with water storage tank by control valve, also have a wireway on the described water storage tank, one end of this wireway is communicated in the control valve lower position, and the other end of wireway is an air guide port, and the position of this air guide port is higher than water storage tank Nei Shui fluid level.
Described wireway passes the diapire of water storage tank and the water liquid in the water storage tank, makes the air guide port on its wireway pass to the interior air chamber of water storage tank.
Described wireway passes the roof of water storage tank, makes the air guide port on the wireway pass to the interior air chamber of water storage tank.
After adopting said structure, owing to be provided with wireway, close at every turn in the water storage tank hot water or after water storage tank feed cold water finishes, surplus water in the water supply and sewage pipe, air guide effect because of wireway, and automatically all emptyings do not need manually-operated, thoroughly solve the surplus water of pipeline and winter water pipe freeze stifled bursting by freezing problem; Also because wireway is set, make total only need adopt a control valve simultaneously, not only make overall structure become more simple, cost reduces, and the user use more convenient, as long as the user opens or closes control valve, can realize the discharging of hot water and stop the discharging; When water storage tank feed cold water, cold water both can directly flow into water storage tank by wireway, also can flow into water storage tank by wireway and control valve simultaneously, and making supplies water becomes very smooth rapid, shortens the feed water time, makes things convenient for the user.
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is the structure chart of a specific embodiment of the utility model water pipe emptying type solar water heater.
Fig. 2 is that another of the utility model water pipe emptying type solar water heater is concrete
The structure chart of embodiment.
Water pipe emptying type solar water heater shown in Figure 1 comprises water storage tank 1 and control valve 10, and control valve 10 adopts magnetic valve, so that remote-controlled operation, the upper end of control valve 10 is loaded on the bottom tank wall of water storage tank 1, and the lower end of control valve 10 then is communicated with water supply and sewage pipe 7.The same with existing water heater water storage tank, a top side wall at water storage tank 1 has the water tank passage 6 that communicates with air chamber 3 in the case,, the air chamber 3 in the water storage tank 1 keeps atmospheric pressure state so that being communicated with atmosphere, air chamber 3 is positioned on the water storage tank 1 of top, water storage tank 1 water liquid 2 planes and also has a wireway 4, one end of this wireway 4 is communicated with control valve 10 lower ends, the other end of wireway 4 is ringent air guide port 5, wireway 4 passes the diapire of water storage tank 1 and continues across the interior water liquid 2 of water storage tank, and the air guide port 5 on it is passed in the air chamber 3 of this water liquid 2 waters surface top, air guide port 5 also communicates with atmosphere.When the feed water valve of opening on the water-main 9, cold water supplies water in case from water storage tank 1 internal upper part through water supply and sewage pipe 7 and wireway 4, and not necessarily will open control valve 10.Open control valve 10, the hot water in the water storage tank 1 flows out downwards through water supply and sewage pipe 7, turns on delivery port 8 and promptly obtains hot water; Closed control valve 10, hot water in the water storage tank 1 stops to flow out, surplus water in the water supply and sewage pipe 7, because the air guide effect of wireway 4 is arranged, continued through all emptyings automatically of delivery port 8, and make water supply and sewage pipe 7 be in emptying state, thus not only made full use of hot water, and reach the effect of surplus water of emptying and antifreeze stifled bursting by freezing.
Fig. 2 has provided another kind of wireway structure, one end of wireway 4 still is communicated with control valve 10 lower ends, 4 of wireways are external around the top to water storage tank 1 from water storage tank, and the roof that passes water storage tank stretches into the air guide port on the wireway 45 in the air chamber 3 in the water storage tank 1, this structure is lower to the seal request between wireway 4 and the water storage tank 1, helps reducing the leakage point on the water storage tank.Certainly, the air guide port 5 on the wireway 4 also can be connected on the water tank passage 6.
