Description

A kind of pair of tank solar water heater

Technical field

The utility model relates to the solar water heater field, specifically is a kind of pair of tank solar water heater.

Background technology

Prior solar water heater, the water tank volume is all bigger, but winter solar energy photo badly, the solar thermal energy that water heater absorbs will be used for heating the water in the whole water tank, its water temperature raises seldom; And prior solar water heater all is to replenish cold water in use, when hydraulic pressure is unstable, promptly causes the phenomenon of water temperature shakiness.

The utility model content

The technical problems to be solved in the utility model provides a kind of pair of tank solar water heater, solve conventional solar boilers water temperature when illumination is not strong raise few, and the problem of water temperature shakiness when using.

The technical solution of the utility model is:

A kind of pair of tank solar water heater comprises fixed mount, is installed in upper water box and lower header on the fixed mount, the bottom of upper water box has water inlet, the bottom of lower header is connected with thermal-collecting tube, is communicated with tube connector between the described upper and lower water tank, is provided with thermostatic valve in the tube connector; Upper and lower water tank was communicated with by communicating pipe, was provided with top hose in the upper water box, and the outer wall of top hose one end is provided with upper floating ball, and its other end is communicated with communicating pipe one end that is positioned at upper water box; Be provided with bottom hose in the lower header, the outer wall of bottom hose one end is provided with down ball float, and its other end outlet pipe interior with introducing lower header is communicated with.

Be communicated with tube connector between described upper water box bottom and the lower header top.

Described top hose and bottom hose are all selected corrugated flexible hose for use.

Described water inlet is provided with water supply valve, and water supply valve water inlet pipe with the be arranged at upper water box interior ball-cock assembly outer with being arranged at upper water box is connected.

The top of the top of described upper water box sidewall and lower header sidewall has upper and lower exhaust outlet, and upper and lower blast pipe is drawn in upper and lower water tank by upper and lower exhaust outlet respectively.

Lower header volume described in the utility model is less, and then the water of Chu Cuning is to less, and after 2-3 hour sunshine, water temperature can reach 50-60 ℃, and when illumination in winter was not strong, its water temperature also can reach 60-70 ℃, has guaranteed the overcast and rainy water that winter or illumination are bad;

When summer, intensity of illumination was big, when the water temperature in the lower header surpasses 80 ℃, the thermostatic valve that is arranged in the tube connector described in the utility model is opened, hot water in the lower header rises in the upper water box, cold water in the upper water box is lowered in the lower header, carry out the hot and cold water exchange, guaranteed that the water temperature in the lower header can be not too high, and guaranteed that the heat that thermal-collecting tube is collected is not lost.

Water in having guaranteed top hose described in the utility model and communicating pipe in the lower header is full all the time, because the water in lower header, when flowing out by bottom hose and outlet pipe, top hose and communicating pipe mend the water in the upper water box in the lower header immediately, guaranteed the abundance of water in the lower header, and an end of top hose and bottom hose is respectively arranged with, following ball float, in the assurance, bottom hose has an end of ball float to be positioned at the water surface all the time, and hot water is little because of density, can rise, more than the institute, the water on upper strata all is the higher water of temperature in the lower header, has guaranteed that the water by the water in top hose and the communicating pipe inflow lower header and bottom hose and outlet pipe outflow all is the hot water that is positioned at the water tank upper strata.

The utility model is simple in structure, has guaranteed the water when illumination is strong, and the design by ball float, has guaranteed to take all the time the hot water on upper strata in the water tank, has improved the utilization rate of hot water.

Description of drawings

Fig. 1 is the structural representation of the utility model embodiment.

The specific embodiment

See Fig. 1, a kind of solar water heater comprises fixed mount 1, is installed in upper water box 2 and lower header 3 on the fixed mount 1, the top of upper and lower water tank 2,3 sidewalls has upper and lower exhaust outlet, and upper and lower blast pipe 16,17 is drawn in upper and lower water tank 2,3 by upper and lower exhaust outlet respectively; The bottom of lower header 3 is connected with thermal-collecting tube 7, the bottom of upper water box 2 has water inlet, the water inlet is provided with water supply valve 4, be connected with water inlet pipe 5 that is positioned at outside the upper water box 2 and the ball-cock assembly 6 that is arranged at upper water box on the water supply valve 4, be communicated with tube connector 8 between the top of the bottom of upper water box 2 and lower header 3, be provided with thermostatic valve 9 in the tube connector 8; Upper and lower water tank 2,3 was communicated with by communicating pipe 10; Be provided with corrugated flexible hose 11 in the upper water box 2, the outer wall of last corrugated flexible hose 11 1 ends is provided with upper floating ball 13, and its 11 other end is communicated with communicating pipes 10 1 end that is positioned at upper water box 2; Be provided with down corrugated flexible hose 12 in the described lower header 3, the outer wall of following corrugated flexible hose 12 1 ends is provided with down ball float 14, and its 12 other end is communicated with outlet pipe 15 in introducing lower header 3.

When intensity of illumination is little, when the water temperature in the lower header 3 is lower than 80 ℃, only use the water in the lower header 3, when intensity of illumination is big, when the water temperature in the lower header 3 surpasses 80 ℃, can the hot water or cold water in the upper and lower water tank 2,3 be exchanged, guarantee that water temperature can be not too high by thermostatic valve 9; During water, water in the upper water box 2 flows into lower header by last corrugated flexible hose 11, the communicating pipe 10 that has upper floating ball 13 successively, the following corrugated flexible hose 12 and the outlet pipe 15 of ball float 14 flow out water in the lower header 3 by having down successively, guarantee to take the upper strata hot water in the upper and lower water tank 2,3 all the time.
