Abstract

The invention relates to a water heater, in particular to a solar water heater, which comprises a main water tank, a heat collecting tube, and a bracket, wherein the side face of the main water tank is provided with an exhaust overflow hole; the main water tank is fixed on the bracket; the solar water heater also comprises an auxiliary water tank provided with a water inlet/outlet; the heat collecting tube comprises an inner tube and an outer tube; a vacuum layer is formed between the outer tube and the inner tube; a layer of coating is coated on the wall of the inner tube; two ends of the heat collecting tube are provided with openings; and one end of the heat collecting tube is connected to the inside of the main water tank, and the other end of the heat collecting tube is connected to the inside of the auxiliary water tank. A dual-opening dual through tube design ensures that the heat collecting tube is easy to clean; and the auxiliary water tank is provided with the water inlet/outlet, so that water in the water heater can be fully utilized and energy is saved.

Description

Solar water heater

Technical field

The present invention relates to a kind of water heater, relate in particular to a kind of solar water heater.

Background technology

Along with the continuous reinforcement of people's environmental consciousness, increasing consumer orientation is in selecting solar water heater.Thermal-collecting tube is the core component of solar water heater, and existing thermal-collecting tube all is the sealing of an end opening one end, forms the shape of U-shaped pipe.At first, running water is easy to generate incrustation scale after heating repeatedly in the thermal-collecting tube of this shape, and be deposited in the blind end of thermal-collecting tube, clean very difficulty, if do not clean for a long time, incrustation scale is cumulative, and the normal use capacity of thermal-collecting tube will be more and more littler, both influence the thermal effect that adds of water heater, influenced the service life of water heater again.Secondly, the intake-outlet of prior solar water heater all is arranged on the main water box, because the level height of intake-outlet is on the thermal-collecting tube, when causing using at every turn, hot water row in the thermal-collecting tube does not come out, and can not get sufficient utilization, causes the waste of the hot water energy in the pipe.

Summary of the invention

In order to overcome the above problems, the invention provides a kind of novel solar water heater, can be good at solving build-up of limescale, difficult problem of cleaning, and can make full use of water storage in the thermal-collecting tube, energy savings.

Technical scheme of the present invention is as follows: solar water heater comprises main water box, thermal-collecting tube, support.Main water box has the exhaustion spill hole, main water box is fixed on the support, also comprise secondary water tank, have paddle hole on the secondary water tank, pipe and outer tube in described thermal-collecting tube comprises form vacuum layer between outer tube and the interior pipe, be covered with the thermal-arrest coating on the inner tubal wall, the two ends of thermal-collecting tube all are opening, and an end of described thermal-collecting tube is connected to main water box inside, and the other end is connected to secondary water tank inside.

Paddle hole can be opened on the sidewall of secondary water tank.Paddle hole can also be opened the bottom at secondary water tank, is positioned under the mouth of pipe of outermost thermal-collecting tube.The capacity of secondary water tank is 1/30 to 1/50 of a main water box.

Secondary water tank can be cuboid, is cylinder, also can be other suitable shapes.

After using design of the present invention, the two ends that the structural design of an end opening one end closure that thermal-collecting tube is traditional makes thermal-collecting tube into all are openings, form a siphunculus, incrustation scale is just difficult like this piles up, because in case heap is had some incrustation scale a little, the bilateral pipe design of two openings also makes the cleaning of thermal-collecting tube become easy especially.And after repacking traditional tail holder the form of secondary water tank into, the incrustation scale that produces in the thermal-collecting tube will natural sedimentation in secondary water tank.And paddle hole is set on secondary water tank, and and water pipe is inserted in the user family, this set at first uses in the time of can guaranteeing to use at every turn is exactly water storage in the thermal-collecting tube, makes that the water in the water heater can both be fully utilized, energy savings.Simultaneously, the cold water that all will be connected to secondary water tank in the indoor water pipe in advance during owing to each the use bleeds off, and in this process, just in time can discharge the incrustation scale impurity that is deposited in the thermal-collecting tube in the secondary water tank.
