Description

Through type hot and cold water tank's solar water heater

The utility model relates to a kind of solar water heater, especially a kind of through type hot and cold water tank's solar water heater.

Sell the solar water heater that uses in the market, its heater vacuum glass heat collection tube one end is uncovered, in the casing that makes up water, the another port sealing, by vacuum glass heat collection tube solar energy being converted to heat energy, is the pollution-free energy that cleans most, is generally used by people.But in use also have a lot of weak points, such as: 1, single water tank water storage capacity is little, the hot and cold water coexistence, and water temperature changes greatly; 2, service time of a specified duration, can make water easily precipitated impurities, incrustation scale in thermal-collecting tube, the long-term use influences Heat-collecting effect, influences water quality, can not drink; 3, need in use can't directly use hot water with just using hot water after the discharge of the cold water in the whole water supply pipeline, therefore, not only use is very inconvenient wastes water again.

The technical problems to be solved in the utility model is: a kind of above-mentioned shortcoming that overcomes is provided, adopt two water tanks and make that water in two water tanks constantly circulates, make water in thermal-collecting tube, do not produce precipitation, impurity and incrustation scale, can blowdown, directly can be put into the solar water heater of hot water.

The technical scheme in the invention for solving the above technical problem is: storage tank is made up of upper water box, end water tank, upper water box, end water tank fit on the bearing respectively, bearing is seen shape triangular in shape from the side, upper water box fits on the made arc surface in the top of triangle bearing, and end water tank fits on the made arc surface in the bottom of triangle bearing hypotenuse; The two ends of the vacuum glass heat collection tube that the endoporus two ends communicate in tank shell, heat-insulation layer, inner water tank and sealing ring are assigned in upper water box, end water tank, make the water conducting in upper water box, the end water tank respectively; Side at end water tank is furnished with water inlet pipe, and the water tank side bottom is furnished with blow-off pipe the end of at; On the top, side of upper water box and the top that is positioned at its inner bag be furnished with outlet pipe, on outlet pipe, be furnished with the threeway blast pipe, on blast pipe, be furnished with air bleeding valve.

The beneficial effects of the utility model: 1, owing to be provided with two water tanks, water is one-way flow in the hot and cold water tank, and water temperature changes little; 2, two water tank water storage capacity are big, can be used as alternate source when accidental cutting off the water, and save water storage facility to the user, saving fund and the space of using tank; 3, utilize the pressure of running water itself, water inlet automatically, how much cold water hot water uses cover automatically, need not manual observation control, and saves manpower, makes things convenient for the user; 4, once having opened hot water, easy to use, hot water utilization rate height.

Specifically describe embodiment of the present utility model below in conjunction with accompanying drawing:

Fig. 1 is a front view of the present utility model;

Fig. 2 is the vertical view of Fig. 1;

Fig. 3 is the A-A amplification profile among Fig. 2.

As Fig. 1, Fig. 2, shown in Figure 3, storage tank is made up of upper water box 8, end water tank 1, upper water box 8, end water tank 1 fit over respectively on the bearing 10, bearing 10 is seen shape triangular in shape from the side, upper water box 8 fits on the made arc surface in the top of triangle bearing 10, and end water tank 1 fits on the made arc surface in the bottom of triangle bearing 10 hypotenuses; The two ends of the vacuum glass heat collection tube 3 that the endoporus two ends communicate are respectively in tank shell, heat-insulation layer 16, inner water tank and sealing ring 13 are assigned in upper water box 8, end water tank 1 body, and the bore of a port of vacuum glass heat collection tube 3 is the uncovered through hole with the pipe orifice same diameter, fit on the upper water box 8, the other end is provided with central through hole 11, its diameter is assigned in the casing of end water tank 1 less than vacuum glass heat collection tube 3 endoporus apertures.Make the water conducting in upper water box 8, the end water tank 1, can not produce sediment.Be furnished with book type stainless steel waveform deflecting plate 5 below several vacuum glass heat collection tubes 3, waveform deflecting plate 5 fits on the support 4, and support 4 solid weldings are on bearing 10.Middle part, side at end water tank 1 is furnished with water inlet pipe 2, is furnished with blow-off pipe 12 in end water tank 1 side bottom; On the top, side of upper water box 8 and the top that is positioned at its inner bag be furnished with outlet pipe 6, on outlet pipe 6, is furnished with threeway blast pipe 7, be shaped on external screw thread in threeway blast pipe 7 mouth of pipe peripheries, one end of air bleeding valve 17 valve bodies is by made being threaded on the blast pipe 7 in its hole, on the made step surface of valve body inner bore, is furnished with activity template 18, is furnished with the spring base 22 that is " fourth " shape above the activity template 18, on spring base 22 central shafts, is furnished with spring 19, the upper end of the central shaft of spring base 22 is shaped on screw thread, its top passes and is fixed on valve gap 20 centre bores of being furnished with on the valve body other end, and with nut 21 regulate required elastic force and mix up activity template 18 and spring base 22 between be fixed behind the required gap.Before the step surface of valve body inner bore, be provided with 6 exhaust holes 11 on the 8mm place wall body circumference.Also can an electric heater unit 15 be installed in upper water box 8 in addition, make and realize light-electricity complementary by at the middle part, side of upper water box 8.

During use, outlet pipe 6 is opened, opening the water tap that is located on water inlet pipe 2 pipelines again realizes adding water in two water tanks, when on water go up in end water tank 1 full after, water flows into upper water boxs 8 through several vacuum glass heat collection tubes 3 again, because outlet pipe 6 fits over the top, side of upper water box 8 and is positioned at the top of its inner bag, so, water is arranged when outlet pipe 6 overflows water when one, illustrate that water in end water tank 1, the upper water box 8 have gone up fullly, close the water tap on the water inlet pipe 2 immediately.Water in water tank obtains heat energy by several vacuum glass heat collection tubes 3, because during the hot and cold water convection current, hot water is always up general, and cold water is always toward descending, so at first heating of water in the upper water box 8, when the hot water temperature in the upper water box 8 progressively increases, progressively produce air pressure in the upper water box 8, adding the outlet pipe 6 of being taken in is in when closing, when the elastic force of the big spring 19 in overcoming air bleeding valve 17 of air pressure, gas outwards discharges by the exhaust hole on the valve body 11, and air bleeding valve 17 played and guaranteed safety effect this moment.Be in normally open following time at outlet pipe 6, a small amount of gas that upper water box 8 is produced can be discharged from outlet pipe 6, also have through hole 11 on the activity template 18 of part from the air bleeding valve 17, again through spring base 22 below and the gap location transferred of activity template 18, the exhaust hole 11 from valve body outwards discharge, make and not all rightly in upper water box 8 and the outlet pipe 6 become vacuum, thereby the water tap one of water inlet pipe 2 is opened, and outlet pipe 6 just can be emitted hot water.After this water heater uses a period of time, blow-off pipe 12 be can open, sediment and dirt in the end water tank 1 bled off.
