Automatic water feeding control system of intelligent solar water heater

Abstract

The invention discloses an automatic water feeding control system of an intelligent solar water heater. The automatic water feeding control system comprises a control panel and a water feeding monitoring device, a normal water utilization mode button, a reserved type water utilization mode button, an input keyboard for setting next water utilization time, a keyboard circuit and a water exchange interval time setting unit are arranged on the control panel, the water feeding monitoring device comprises a data storage unit, a data processing device, a display unit, a clock circuit and a water shortage alarm unit, a first electromagnetic control valve on a water feeding pipe on the solar water heater, an electric water pump and a second electromagnetic control valve installed at the upper end of a sewer pipe are controlled by a controller, a water temperature detection unit and a water level detection unit are arranged in a heat preservation water tank, and a data processor is connected with the controller. The automatic water feeding control system is reasonable in circuit design, low in investment cost, easy and convenient to use and operate, high in intelligent degree, good in using effect and capable of conducting automatic water feeding control according to the normal water utilization mode or reserved type water utilization mode selected by a user.

Description

technical field [0001] The invention relates to a control system, in particular to an intelligent solar water heater automatic water supply control system. Background technique [0002] The working principle of solar water heaters is to collect the heat emitted by sunlight through vacuum tubes and use the collected heat to heat water. Therefore, vacuum tubes are the key components of solar water heaters. Since the vacuum tubes are black tubes, they are conducive to absorbing the radiant heat of sunlight. At the same time, due to The vacuum tube is double-layered and vacuumed, so that the heat is not easily dissipated to the outside. Solar energy is radiant energy. The inner surface of the vacuum tube is coated with a radiation-absorbing coating and there is metal (copper) with good heat transfer effect in the tube to transfer to the water tank through heat conduction. sheet"), warming the cold water by heat exchange and exchanging heat by convection, so that the cycle conti...

Problems solved by technology

However, in real life, it often happens that the user has not used the solar water heater for a long time, so the hot water in the thermal insulation tank will not flow for a long time, which not only affects the service life of the solar water heater itself, but also cannot avoid the long-term storage of water. The land will be polluted by many kinds, thus causing a certain degree of waste of water resources

Therefore, there is a lack of an automatic water supply control system for solar water heaters with reasonable circuit design, low input cost, easy operation, high intelligence, and good use effect, which can be used according to the normal water consumption mode or reserved water consumption selected by the user. Mode Automatic for water filling control
