A kind of solar energy heating direct drinking device
[technical field]
The present invention relates to a kind of solar energy heating direct drinking device.
[background technology]
Direct and the solar energy circulation heating of the device direct drinking of existing solar energy heating direct drinking, such weak point is: direct drinking and solar thermal collector circulation time can cause the pollution of direct drinking, should not drink.
[summary of the invention]
The present invention has overcome the deficiency of above-mentioned technology, and a kind of solar energy heating direct drinking device that can not cause the pollution of direct drinking is provided.
For realizing above-mentioned purpose, the present invention has adopted following technical proposal:
A kind of solar energy heating direct drinking device; Comprise water tank 1 that direct drinking is housed and be the solar energy circulating heater 2 of direct drinking heating; Said solar energy circulating heater 2 comprises solar thermal collector 3 and the stainless steel coil pipe 4 that places in the water tank 1 and carry out heat exchange with direct drinking; Cold water inlet 31 and hot water outlet 32 that said solar thermal collector 3 is provided with heating chamber and is communicated with this heating chamber; Said cold water inlet 31 is connected with stainless steel coil pipe 4 one ends through cold-water reflux pipe 5, and said hot water outlet 32 is connected with stainless steel coil pipe 4 other ends through hot water outlet pipe 6; Heating chamber on the said solar thermal collector 3; The hot water outlet pipe 6; Stainless steel coil pipe 4 and cold-water reflux pipe 5 are linked to be circulation canal, on hot water outlet pipe 6, are provided with to extract the hot water in the solar thermal collector 3 out be back to solar thermal collector 3 then through stainless steel coil pipe 4 again from cold water inlet 31 circulating pump 7 from hot water outlet 32.
The present invention also includes water supply tank 8, and the delivery port of water supply tank 8 is communicated with the cold water inlet 31 of solar thermal collector 3.
The invention has the beneficial effects as follows: the direct drinking in the water tank can directly not contact with solar thermal collector, has avoided direct drinking contaminated.

[specific embodiment]
A kind of solar energy heating direct drinking device; Comprise water tank 1 that direct drinking is housed and be the solar energy circulating heater 2 of direct drinking heating; Said solar energy circulating heater 2 comprises solar thermal collector 3 and the stainless steel coil pipe 4 that places in the water tank 1 and carry out heat exchange with direct drinking; Cold water inlet 31 and hot water outlet 32 that said solar thermal collector 3 is provided with heating chamber and is communicated with this heating chamber; Said cold water inlet 31 is connected with stainless steel coil pipe 4 one ends through cold-water reflux pipe 5, and said hot water outlet 32 is connected with stainless steel coil pipe 4 other ends through hot water outlet pipe 6; Heating chamber on the said solar thermal collector 3; The hot water outlet pipe 6; Stainless steel coil pipe 4 and cold-water reflux pipe 5 are linked to be circulation canal, on hot water outlet pipe 6, are provided with to extract the hot water in the solar thermal collector 3 out be back to solar thermal collector 3 then through stainless steel coil pipe 4 again from cold water inlet 31 circulating pump 7 from hot water outlet 32.
The present invention also includes water supply tank 8, and the delivery port of water supply tank 8 is communicated with the cold water inlet 31 of solar thermal collector 3.Regularly mend cold water through 8 pairs of solar thermal collectors of water supply tank 3.
Operation principle of the present invention is following: when solar thermal collector 3 reached uniform temperature, circulating pump 8 started.Hot water flows to stainless steel coil pipe 4 from hot water outlet 32 outflows of solar thermal collector 3 through hot water outlet pipe 6; Hot water in the stainless steel coil pipe 4 and the direct drinking in the water tank carry out heat exchange; Direct drinking is heated up gradually, and the water-cooled in the stainless steel coil pipe after the heat exchange 4 but and flows back to the heating chamber on the solar thermal collector 3 through cold water inlet 31; Continue heating, so circulation is the heating of the direct drinking in the water tank.Above-mentioned heating process, direct drinking can directly not contact with solar thermal collector and pollute, and reach the purpose of heating direct drinking.
