(5) specific embodiment

Explain below the solar water heater work below in conjunction with 1 pair of a kind of non-pressure automatic hot water-first-out of the present utility model of accompanying drawing.

As shown in Figure 1, the solar water heater of a kind of non-pressure automatic hot water-first-out of the present utility model, its structure comprises the water tank 4 and the water inlet pipe 6 and the outlet pipe 13 that are arranged on the water tank 4 of prior art, water inlet pipe 6 is provided with water controller 3, the top that is positioned at the water tank 4 of outlet pipe 13 tops is provided with breather pipe 8, breather pipe 8 is provided with one-way cock 7, its innovative point is that division board 11 has been installed in water tank 4, division board 11 has been divided into the left chamber at water inlet pipe 6 places and the right ventricle at outlet pipe 13 places with water tank 4, at top, left chamber breather pipe 1 has been installed, connect with communicating pipes 5 between a left side chamber and the right ventricle, the position that is in the water inlet 2 on communicating pipe 5 of left chamber must be higher than delivery port 12 that is in the right ventricle and the position that is lower than water surface site 9.

Division board 11 is not set in water tank 4, before communicating pipe 5 and the breather pipe 1, when outlet pipe 13 discharges water, the valve of the water controller of installing on the water inlet pipe 63 will be opened into water, when in case water supply pressure hangs down, the one-way cock of installing on the breather pipe 87 will be closed, the air of outside can't enter in the water tank 4 and replenish, because solar water heater is very long to the distance in bathroom, the length of outlet pipe 12 is generally between several meters to tens meters, if water supply pressure is very low, the powerful pulling force of letting out under water in the outlet pipe 13 makes and produces the damage that very big negative pressure may cause water tank 4 in the water tank 4.
