Description

Technical Field

[0001] This utility model relates to the field of solar water heater technology, specifically to a smart controller for household solar water heaters based on Internet of Things (IoT) technology. Background Technology

[0002] Solar water heaters are typically installed on the rooftops of multi-story buildings. Their use has brought great convenience to people's lives, saving on household energy costs and offering greater safety than gas or electric water heaters. Hot water is available as long as there is sunshine, making them low-cost and highly convenient, and thus very popular. However, when filling the solar water heater, the sound of water flowing is very faint when the tank is not full, easily overlooked, leading to frequent instances of forgetting to turn off the water valve. If someone is away and forgets to turn off the water valve, the consequences could be disastrous. Every year, there are instances of indoor flooding caused by forgetting to turn off the solar water heater valve, potentially resulting in serious property damage and even endangering lives.

[0003] For example, patent application CN201610427941.2 includes a thermal energy conversion unit, an electrical energy conversion unit, a display unit, and a control unit. The thermal energy conversion unit converts absorbed solar radiation energy into thermal energy, and the electrical energy conversion unit converts absorbed solar radiation energy into electrical energy and stores the electrical energy. The control unit stores a preset time and a preset temperature. Within the preset time, when the temperature sensor's detection value is lower than the preset temperature, the control unit further analyzes the relationship between the temperature sensor's detection value and the preset temperature, and according to the range of the temperature sensor's detection value, it controls the heating element to heat the water in the insulated water tank in stages. When the water temperature in the insulated water tank is high, fewer heating devices are used to heat the water; when the water temperature in the insulated water tank is low, more heating devices are used to heat the water, until the temperature in the insulated water tank reaches the preset temperature.

[0004] The aforementioned and existing intelligent control systems in this technology cannot automatically stop filling the water tank once it is full, requiring users to constantly monitor the water level and remain present, thus wasting their time. If users are busy with other tasks during the filling process, they may easily forget that the tank is still filling, leading to water overflow and waste. Furthermore, the start and stop of the filling process require manual operation, which is inconvenient. Therefore, there is an urgent need to design an intelligent controller for household solar water heaters based on Internet of Things (IoT) technology to solve these problems. Utility Model Content

The controlled device 6 then controls the electromagnetic water valve 7 to close, stopping the solar water heater from filling with water. This prevents the user from forgetting to fill the storage tank 2, which could lead to water overflow and waste, thus increasing the effectiveness of the solar water heater smart controller.
