Abstract
The utility model provides an antifreeze solar water heater, comprising a main water tank, a subsidiary water tank, a water inlet, and a water outlet. Wherein, the subsidiary water tank is arranged on the top part of the main water tank and communicated with the main water tank, and the upper end of the subsidiary water tank is provided with an air exit hole. The water inlet and outlet pipes with control valves are inserted correspondingly into the subsidiary water tank and the main water tank; the tail end of the water inlet pipe is provided with a floating ball valve. The antifreeze solar water heater is characterized in that the main water tank is the non loading pressure water tank whose hot water outlet is positioned on the top end of the main water tank; on the water inlet pipe, the upper end positioned on the control valve is added with a discharge valve whose one end is communicated with the water inlet pipe. When water in the water inlet and outlet pipes needs to be discharged in the winter, nothing remains but to close the control valve on the water inlet pipe; the discharge valve and the control valve on the water outlet pipe are opened, so the small amount of the water positioned above a hot water outlet flows out from the water outlet pipe; the cold water in the water inlet pipe is discharged through the discharge valve. Consequently, the frost crack of the pipeline is avoided effectively, and the use performance of the system is enhanced; in addition, the antifreeze solar water heater has simple structure, convenient maintenance, easy installation, convenient operation, and low cost.
Description
Described technical field
The utility model relates to solar water heater, specifically is a kind of anti-freezing solar water heater with air emptying function.
Background technology
Solar water heater makes full use of solar energy, pollution-free, advantage that use cost is low with it, is subjected to liking of users deeply.The following defective of currently marketed various water heater ubiquities when promptly using northerly winter, easily causes freezing in the upper and lower water pipe, not only blocks flowing water, also can freezing water pipe when serious, and cause water heater to damage.At the problems referred to above, the existing at present technology report that addresses the above problem, as Chinese patent communique disclosed utility model patent in 21 days February calendar year 2001: a kind of siphonic solar water heater, the patent No.: 00208125, comprise storage tank, upper and lower conduit, blast pipe, overflow pipe, it is characterized in that, upper and lower conduit from storage tank top or the side stretch into storage tank bottom, connect an antisyphonage pipe on the top of upper and lower conduit; In the side of water heater storage tank blast pipe and overflow pipe are housed, the part of overflow pipe in storage tank is a downward bend pipe.Antisyphonage pipe can make upper and lower conduit emptying when stopping Inlet and outlet water, antifreeze, and the part of overflow pipe in storage tank is a downward bend pipe, has siphonage, when overflow is stopped, in the overflow pipe not water, do not freeze.Defective is structure and complicated operation, the cost height.
Summary of the invention
The purpose of this utility model provides and a kind ofly can overcome above-mentioned defective, simple in structure, easy to operate, anti-freezing solar water heater that cost is low.Its technical scheme is:
Comprise main water box, secondary water tank, water inlet pipe and outlet pipe, wherein secondary water tank is arranged on the main water box top and is communicated with main water box, its upper end is provided with steam vent, the water inlet pipe, the outlet pipe correspondence that have control valve probe in secondary water tank, the main water box, end at water inlet pipe is provided with ball-cock assembly, it is characterized in that: main water box is non-press-bearing water tank, and its hot water outlet is positioned at the upper end of main water box, exhaust-valve is set up in the upper end that is positioned at control valve on water inlet pipe, and an end of exhaust-valve is communicated with water inlet pipe.
Described anti-freezing solar water heater, control valve, exhaust-valve on the water inlet pipe are merged into triple valve.
Described anti-freezing solar water heater, the bottom of secondary water tank is provided with the bottom that pipeline probes into main water box, and the pipe side wall that is positioned at main water box is provided with pore.
Its operation principle is: during water, close exhaust-valve, open on the inlet tube and outlet tube control valve, cold water is just mended into main water box through secondary water tank in a steady stream, the hot water in the main water box just hot water outlet through being positioned at its upper end flows out, and supplies people's bathing.When needing the water in the emptying water-in and water-out pipeline in the winter time after the water, only need close the control valve on the water inlet pipe, open the control valve on exhaust-valve and the outlet pipe, be positioned at the above low amounts of water of hot water outlet in the main water box and just flow out from outlet pipe, the cold water in the water inlet pipe is discharged by exhaust-valve, so just effectively avoided the bursting by freezing pipeline, improved the serviceability of system, and simple in structure, be convenient to safeguard, installation, easy to operate, cost is low.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
The specific embodiment
1, main water box 2, secondary water tank 3, steam vent 4, ball-cock assembly 5, water inlet pipe 6, control valve 7, exhaust-valve 8, pore 9, outlet pipe 10, hot water outlet 11, pipeline
Main water box 1 is non-press-bearing water tank, be communicated with the outlet pipe 9 that has control valve 6, its hot water outlet 10 is positioned at the upper end of main water box 1, secondary water tank 2 is arranged on main water box 1 top, its bottom is provided with the bottom that pipeline 11 probes into main water box 1 and is communicated with main water box 1, pipeline 11 sidewalls that are positioned at main water box 1 are provided with pore 8, be used for the air in the main water box 1 is entered in the secondary water tank 2, the upper end of secondary water tank 2 is provided with steam vent 3, its side is equipped with the water inlet pipe 5 of band control valve 6, the upper end that is positioned at control valve 6 on water inlet pipe 5 is provided with exhaust-valve 7, and an end of exhaust-valve 7 is communicated with water inlet pipe 5, is provided with ball-cock assembly 4 at the end of water inlet pipe 5.When needing the water in the emptying water-in and water-out pipeline in the winter time after the water, only need close the control valve 6 on the water inlet pipe 5, open the control valve 6 on exhaust-valve 7 and the outlet pipe 9, being positioned at the low amounts of water of hot water outlet more than 10 in the main water box 1 just flows out from outlet pipe 9, cold water in the water inlet pipe 5 is discharged by exhaust-valve 7, so just effectively avoided the bursting by freezing pipeline, and the water of discharging is also less, a large amount of water avoids waste.
Control valve on water inlet pipe, exhaust-valve also can be merged into triple valve.
