Outdoor anti-freezing type solar water heater

Abstract

The invention discloses an outdoor anti-freezing type solar water heater. The outdoor anti-freezing type solar water heater comprises a control device, a heating device and a power supply, wherein thecontrol device is correspondingly in electrical connection with the power supply and the heating device, the power supply comprises a wind power generation power source and a photovoltaic power generation power source, the wind power generation power source and the photovoltaic power generation power source are correspondingly in electrical connection with the heating device through the control device, and the control device is used for coordination control over the wind power generation power source and the photovoltaic power generation power source to supply power for the heating device; awater outlet control valve is arranged on the water inlet end of a water outlet pipeline which is close to the solar water heater, when the water outlet control valve is opened, water in the solar water heater is discharged; and when the water outlet control valve is controlled to close, the reserved water in the water outlet pipeline is discharged. According to the outdoor anti-freezing type solar water heater, power supplying for the heating device is carried out through the electric energy generated by the wind power generation and the photovoltaic power generation, novel energy is utilizedfully, meanwhile the water outlet pipeline communicates with the atmosphere when the water outlet valve is closed, the reserved water in the water outlet pipeline is discharged automatically, and thecondition that later use is affected by pipeline freezing due to the fact that the outdoor temperature is too low is avoided.

Description

technical field [0001] The invention relates to the technical field of solar water heaters, in particular to an outdoor antifreeze solar water heater, which is suitable for rural areas in northern regions with cold winters or for outdoor application. Background technique [0002] In view of the cold nights and continuous cloudy days in the northern region, the solar water heater will freeze and crack, so the solar water heater in the northern region can only be stopped in winter. [0003] Solar water heaters have been widely used in China at present. Users of these solar water heaters will face a very big problem. After the temperature is low in winter and the night temperature reaches below zero, the water stored in the outlet pipe of the outdoor solar water heater will freeze, resulting in The inlet and outlet pipes of the solar water heater are broken, which not only affects the daily life of the user, but also is inconvenient and expensive to repair. Some users use spec...

Problems solved by technology

[0003] Solar water heaters have been widely used in China at present. Users of these solar water heaters will face a very big problem. After the temperature is low in winter and the night temperature reaches below zero, the water stored in the outlet pipe of the outdoor solar water heater will freeze, resulting in The inlet and outlet pipes of the solar water heater are broken, which not only affects the daily life of users, but also inconvenient and expensive to repair

Some users use special pipes to wrap the heating cables. When the outlet pipe of the solar water heater is frozen, they use electric heating to melt the ice in the pipe. However, this method wastes user time and electricity, and brings economic losses and inconvenience to life.
