Problems solved by technology
However, the installation of the control device requires the modification of the existing water supply valve. For some families whose pipes and valves have been buried in the wall during decoration, it is difficult to install the device.
Moreover, the original induction device only relies on the current of the generator to transmit wireless signals, and the impact energy of the airflow and water flow on the impeller needs to be concentrated to a certain extent to send out a strong enough signal. There will be a delay in control, how to further improve on the basis of it, and provide an automatic water supply control system for solar water heaters that is easy to install and has higher control efficiency has become a technical problem to be solved urgently

The invention discloses an automatic water feeding control system of a solar water heater. The automatic water feeding control system comprises a control device mounted on a water feeding pipe of the solar water heater and an induction device mounted on an overflow pipe. The control device is in signal connection with the induction device. The induction device comprises a sensor and a signal emission device. The sensor is used for converting air flow and / or water flow in a pipeline into electric signals. The control device comprises a valve, an integrated controller and an executing mechanism. The integrated controller is used for receiving signals and controlling the executing mechanism. The executing mechanism comprises a motor and a gear set. An output shaft of the motor is connected with the input end of the gear set. The output end of the gear set is connected with a valve rod of the valve. By adopting the automatic water feeding control system, water can be automatically fed into the solar water heater; the automatic water feeding control system is low in cost, convenient to install and high in reliability and has wide application prospects.
Description
technical field [0001] The invention relates to a control device for a solar heat collector, in particular to an automatic water supply control system for a solar water heater. Background technique [0002] my country has become the world's largest producer of solar water heaters and the largest market for solar water heaters. With its advantages in energy saving and environmental protection, solar water heaters account for more than 40% of the entire water heater industry. Since the water storage tank and heat collecting pipe of the solar water heater need to be installed on the outdoor roof, its extensive use mode determines that its water supply device should not be too complicated. At present, most solar water heaters still use manual water filling, that is, manual valve control. When water needs to be replenished, the valve is opened. Manual watering is the most reliable and relatively simple. But it takes a lot of time, especially the waiting time, and if the user fo...
