Solar water heater with additional water pumping device

Abstract

The invention discloses a solar water heater with an additional water pumping device and relates to the field of emptying. The solar water heater mainly comprises a shell, a hot water barrel, a waterinlet and outlet pipe, a stop valve, a vent valve, a hot water pump and the like. When a pipeline needs to be emptied, a user just needs to open a pipe orifice of an air pipe and meanwhile turns on anindoor water control valve, and then hot water in the pipe can be emptied. When the user needs to take and use solar hot water again, the user turns on the indoor water control valve first, meanwhilecloses the pipe orifice of the air pipe of the vent valve, then turns on the stop valve to communicate the hot water pump with a hot water pipe led into a room to make the hot water pump operate andturns off the hot water pump and the stop valve after hot water flows out from the indoor water control valve. At the moment, the hot water in the barrel automatically flows to the indoor pipe under the siphoning action, and now normal water taking from the water heater is achieved. The solar water heater has the advantages that the shell has the heat insulation effect; the hot water barrel, the hot water pump and the like are all arranged in the shell to guarantee that the hot water barrel, the hot water pump and the like cannot be frozen; moreover, the use time of motion components is short,and the motion frequency of the motion components is low, so that the service life of the motion components is long, and the reliability of the motion components is good.

Description

technical field [0001] The invention relates to an antifreeze and emptying device for a solar water heater, which is used in ordinary families, hotels and bathing industries, and belongs to the field of daily necessities. Background technique [0002] At present, although solar water heaters are widely used in places such as ordinary families, hotels and bathing industries, the antifreeze of their pipelines in winter is still a problem worthy of attention. Since the late last century, various pipeline emptying technologies have emerged continuously, which to a certain extent avoided the freezing of solar water heater pipelines in winter and eliminated consumers' doubts. Therefore, this technology was once widely used. However, since solar water heaters are located outdoors (and mostly on the top of buildings), the environment is special, the climate varies greatly across my country, and the technology is not mature enough. The anti-freezing and emptying of pipelines is ineff...
