Abstract

The invention discloses an anti-freezing device for a solar water heater. The anti-freezing device comprises a water heater water tank, the interior of the water heater water tank is spirally connected with a siphon and a connecting water pipe through a first three-way valve, the top end of the first three-way valve is connected with an electromagnetic valve, the connecting water pipe is connected with a shower water pipe through a second three-way valve and is connected with a tap water pipe through a third three-way valve, the bottom end of the connecting water pipe is spirally connected with a heating water tank through a spiral joint, the interior of the heating water tank is fixedly connected with a heater through a fixed joint, the fixed joint and the electromagnetic valve are connected with a controller through connecting leads, and a control switch is arranged on the controller. According to the anti-freezing device, the electromagnetic valve is arranged so that water inside the connecting water pipe can be discharged, the connecting water pipe is prevented from being frozen, the connecting water pipe is protected, and therefore the use is convenient and the anti-freezing effect is good.

Description

technical field [0001] The invention relates to the technical field of solar water heaters, in particular to an antifreeze device for solar water heaters. Background technique [0002] A solar water heater is a heating device that converts sunlight energy into heat energy, and heats water from low temperature to high temperature, so as to meet the hot water use in people's life and production. Solar water heaters are divided into vacuum tube solar water heaters and flat plate solar water heaters according to their structure. The vacuum tube solar water heaters are the main ones, accounting for 95% of the domestic market share. Vacuum tube household solar water heaters are composed of heat collecting tubes, water storage tanks, brackets and other related parts. The conversion of solar energy into heat mainly depends on vacuum heat collecting tubes. Get the hot water you need. [0003] The antifreeze device for solar water heaters is a protective device for antifreezing sola...
