Abstract
The utility model relates to a water tank of solar water heater, comprising a water tank, a vacuum tube set port, an inlet and an outlet and a valve of the upper and the lower water pipes. A heat insulating layer dividing the water tank into an upper and the a lower part is arranged in the water tank and a floating board is arranged in the heat insulating board. When the water tank is filled of water in summer, the floating board floats, making the communication between he upper and lower parts of the water tank; when the water with a high temperature is needed in winter, water will be filled only in the lower part of the water tank, and the floating board can slide down onto the insulating layer by the gravity force, making the enclosure of the upper part of the water tank. Therefore, the utility model can make more hot water in summer and the hot water with proper temperature in winter.
Description
The utility model relates to the light energy of utilizing solar energy, and water temperature is raise, and with the heat production water device of it storage.
At present, the water tank volume of known solar water heater is fixed, because of intensity of illumination is different with light application time throughout the year, if waterbox design is bigger like this, then just do not reach the water temperature that needs winter, waterbox design is smaller, and then summer just can not well-off water yield.
The purpose of this utility model provides a kind of solar water heater water tank, adopts some measures, solves the above-mentioned shortcoming of putting forward.
The utility model is achieved in that it comprises that water tank and opening form at the vacuum tube group interface of water tank bottom and upper and lower conduit water inlet and delivery port and valve.Have a thermal insulation layer that water tank is divided into two parts up and down in water tank, gas outlet is arranged on the thermal insulation layer, dress proportion has guide rail to pass the buoyancy aid plate and is fixed on the water tank less than the buoyancy aid plate of water on the thermal insulation layer, and the buoyancy aid plate can slide on guide rail.When water tank was filled with water, the buoyancy aid plate was under buoyancy, and the buoyancy aid plate leaves thermal insulation layer along guide rail, make water tank up and down two parts communicate, the light energy that vacuum tube obtains makes the water in the water tank obtain to heat up by the convection current of water.When the top water tank was anhydrous, the buoyancy aid plate slipped back on the thermal insulation layer along guide rail under the gravity effect, and the water tank lower part is closed, and the heat that water tank lower part water obtains can not outwards distribute.Also can on water tank, adorn a circulation pipe, fill with water after, water tank up and down two parts, gas outlet, circulation pipe forms the water that Natural Circulation makes whole water tank and obtains to heat up.The delivery port of the downcomer in the water tank is in the lower part of water tank.
Owing to adopted such scheme, can have the more water yield, winter that suitable hot water supply is arranged again in summer.
Below in conjunction with drawings and Examples the utility model is further specified:
Fig. 1 is vertical section structure figure of the present utility model (water tank is filled with water state).
Fig. 2 is the cutaway view (water tank upper divide anhydrous state) of Fig. 1 along I-I ' line.
Among Fig. 1,1, water tank 2, thermal insulation layer 3, buoyancy aid plate 4, circulation pipe 5, guide rail 6, gas outlet 7, gas outlet 8, upper hose hold concurrently downcomer 9, upper hose ball-cock assembly 10, check valve and downcomer delivery port 11, summer upper hose 12, summer upper hose float valve 13, summer upper hose float valve ball float 14, upper hose hold concurrently downcomer valve 15, summer upper hose valve 16, total upper hose valve.
Winter or when needing frequent water or needing water temperature higher, running water enters water tank (1) from total upper hose valve (16) of opening through hold concurrently downcomer (8) downcomer valve (14) and ball-cock assembly (9) of upper hose, when water tank (1) when water is filled with in the lower part, ball-cock assembly (9) is closed, and the upper hose downcomer (8) of holding concurrently stops to go up water.
Other season, open upper hose valve in summer (15), water enters water tank (1) through aestivate upper hose (11) and delivery port float valve (12), when water tank (1) when the lower part is filled with, water enters the water tank upper branch from gas outlet (7), buoyancy aid plate this moment (3) floats along guide rail (5), after filling with water, ball float (13) the tension flotation line of float valve (12) is closed float valve (12), whole water tank (1) communicates, and water heats up by convection current or two parts, gas outlet (7), circulation pipe (4) formation Natural Circulation heat up water up and down by water tank (1).
Check valve and downcomer delivery port (10) water outlet by being installed in water tank (1) lower part during water, after the water on water tank (1) top flowed out, buoyancy aid plate (3) slided to thermal insulation layer (2) along guide rail (5) under the gravity effect.
Claims (4)
1, a kind of solar water heater water tank comprises water tank and the opening interface in the vacuum tube group of water tank lower part, the water inlet of upper and lower conduit and delivery port and valve are formed, it is characterized in that having in the water tank (1) thermal insulation layer (2) that water tank (1) is divided into two parts up and down, gas outlet (7) is arranged on the thermal insulation layer (2), and downcomer delivery port (10) is in the lower part of water tank (1).
2,, it is characterized in that having on the thermal insulation layer (2) the buoyancy aid plate (3) of proportion less than water according to the described water tank of claim 1.
3,, it is characterized in that the last affixed guide rail (5) of water tank (1) and pass buoyancy aid plate (2) that buoyancy aid plate (2) can be gone up at guide rail (5) and slide according to claim 1,2 described water tanks.
4,, it is characterized in that upward dress circulation pipe (4) of water tank (1) according to the described water tank of claim 1.
