The utility model has the advantages of that the heat loss is small, and the water tank wall, in particular to the bottom is uneasy to scale, and the filter screen of the outlet of the exhaust pipe can avoid the entry of flies to pollute water; the stainless anti-dust ring and the stainless decoration ring are used to really guarantee the service life of the water heater.

Description

Solar water heater

Technical field

The utility model relates to solar water heater.

Background technology

Solar water heater is that a kind of solar energy that utilizes is a kind of light and heat energy conversion equipment of cold water heating.Shown in Figure 1 is existing a kind of solar water heater, this solar water appliance has support 2, be fixed on the water tank 1 on the support, the vacuum heat collection pipe 3 that is connected

water tank

1 and 21 of support tailstocks side by side and communicates and be in vacuum heat collection pipe 3 belows and be fixed on diffuse reflector on the support with the water tank chamber, in water tank 1 generally has, shell, in, be filled with insulation material between shell, said solar-energy water heater utilizes cold water than the heavy principle of hot water, cold water sinks, hot water rises, this free convection circulation makes the heated water in the vacuum tube constantly flow to heat storage water tank.Water tank 1 has upper and lower conduit 8 and overflow blast pipe 6-7, upper and lower conduit and overflow blast pipe are arranged on the side of water tank, wherein upper and lower conduit 8 is in the bottom of water tank, and overflow blast pipe 6-7 is on the top of water tank, because the bottom surface of upper and lower conduit and water tank has certain distance, and the end face of overflow blast pipe and water tank also has certain distance, when discharging water, the water in the water tank is put endless like this, and when water inlet, water is adorned discontented again, and heat storage water tank is not fully utilized.

Summary of the invention

The purpose of this utility model is to propose a kind of water can fill the solar water heater that water tank can drain again.

The major technique measure that the utility model is taked is that the inner casing top of water tank has two projectioies that make progress, inner shell bottom has a calixconcavity, wherein a projection under be provided with overflow pipe, be provided with blast pipe under another projection, overflow pipe and blast pipe all stretch out from housing bottom, the upper shed of overflow pipe is equal with the bottom of the projection of its top, the upper shed of blast pipe exceed overflow pipe upper shed but must and the roof of projection of its top between leave the gap, the calixconcavity lowest part is provided with opening, connects upper and lower conduit on the opening.

Above-mentioned water tank is provided with electrothermal tube in the chamber.

The exit of above-mentioned blast pipe is provided with filter screen.

Junction with water tank on vacuum heat collection pipe is provided with the stainless steel dust ring.

Junction with the support tailstock on vacuum heat collection pipe is provided with the stainless steel case ring.

The utility model is because the upper shed of upper and lower conduit is in the lowest part in water tank chamber, so can guarantee that the water in the water tank has all been put, the upper shed of overflow pipe is equal with the bottom of this projection, so water is being full of whole water tank and is entering in the protruding chamber, water just can be discharged from overflow pipe, guarantees to be full of water in the water tank.

The utility model decapacitation also has following advantage outside above-mentioned purpose:

1. overflow pipe and blast pipe take that Open Side Down passes water tank bottom, it is a kind of all risk insurance temperature design, because hot-air constantly rises, cold air is difficult for carrying out heat exchange with the interior hot gas of water tank around making the pipe opening part, so heat loss of the present utility model is less, be installed in the solar water heater of water tank upper with common blast pipe, can improve 6～12 ℃ of water temperatures.

2. because water tank 100% filling up water, 100% drains water, so especially the bottom is less scaling for water tank wall.

3. the exit of blast pipe is provided with stainless steel filtering net, prevents that snail, gecko, mosquitos and flies from entering water tank and polluted water.

4. adopt stainless steel dust ring, stainless steel case ring, stainless steel filtering net, both strengthened outward appearance U.S., changing rubber and plastic spare easy aging cracking under daylight again needs the often phenomenon of transposing, and the service life of really guaranteeing water heater is more than 15 years.
