Description

Technical Field

[0001] The utility model relates to the technical field of solar water tanks, in particular to a full-automatic heat-locking solar water tank. Background Art

[0002] Solar water heaters convert sunlight into heat energy and heat water from low temperature to high temperature to meet people's hot water needs in life and production. Solar water heaters are divided into vacuum tube solar water heaters and flat plate solar water heaters according to their structural form. At present, vacuum tube solar water heaters are the main ones on the market, accounting for 95% of the domestic market share. Vacuum tube household solar water heaters are mainly composed of heat collecting tubes, water storage tanks, brackets and other related accessories. The conversion of solar energy into heat energy mainly depends on the heat collecting tubes. The heat collecting tubes use the principle that hot water floats and cold water sinks to make the water produce microcirculation and achieve the required hot water. However, the existing water heater tank is directly connected to the water pipe. When adding water, it is necessary to manually open the water pipe. After adding water to the water tank, the original remaining hot water will also become cold and cannot be used, causing inconvenience in the use of the water heater. Utility Model Content

The water injection pipe serves as a backup water injection pipeline. When a power outage occurs, the solenoid valve cannot work and the first water injection pipe cannot inject water. The ball valve is manually opened to inject water into the auxiliary water tank through the second water injection pipe. An electric control box is installed on the end face of the auxiliary water tank. A transformer and a relay are installed in the electric control box. The transformer is connected to an external power supply. The relay is electrically connected to the transformer and the solenoid valve. The electric control box is electrically connected to the solenoid valve, the first liquid level sensor, and the second liquid level sensor respectively. The water level in the auxiliary water tank is detected by the first liquid level sensor and the second liquid level sensor. When the first liquid level sensor detects the lowest water level, the relay in the electric control box controls the solenoid valve to open, and water is added to the auxiliary water tank and the main water tank through the first water injection pipe. When the second liquid level sensor detects that the water level has reached the highest, the solenoid valve is closed and water replenishment stops.

[0004] As a preferred solution of the utility model, the auxiliary water tank has an opening at the top and is sealed with a water tank cover, which facilitates maintenance of the interior of the auxiliary water tank.

[0005] The beneficial effects of the utility model are as follows: an auxiliary water tank is added to the original main water tank, two water filling pipes are connected to the auxiliary water tank, a solenoid valve is installed on the first water filling pipe, and the water level in the auxiliary water tank is detected by a liquid level sensor, so that the solenoid valve controls the first water filling pipe to replenish water to the main water tank and the auxiliary water tank, and automatic water replenishment can be achieved without manual operation, which is convenient to use. The liquid level sensor can be used to control water replenishment when the water level in the water tank reaches the lowest, thereby making full use of the hot water in the water tank, ensuring the utilization rate of the hot water in the water tank, and making the water tank have a better heat locking effect. The second water filling pipe is manually controlled to complete the water replenishment of the auxiliary water tank, and can be used as an emergency backup water filling pipeline during power outages, making the use of the water tank more reliable.

The main water tank 1 is connected to the secondary water tank 4 through the connecting pipe 2, and the top of the inner cavity of the secondary water tank 4 is lower than the top of the inner cavity of the main water tank 1, so as to ensure that after the secondary water tank 4 is filled with water, a certain space is reserved on the top of the main water tank 1, and it will not be filled with water, and a certain air storage space is reserved. The bottom of the auxiliary water tank 4 is connected to the first water injection pipe 3 and the main water tank 1 through a three-way joint, and a solenoid valve 7 is installed on the first water injection pipe 3. The bottom and top of the inner cavity side wall of the auxiliary water tank 4 are respectively installed with a first liquid level sensor 9 and a second liquid level sensor 10. The side of the auxiliary water tank 4 is connected to the second water injection pipe 5, and a ball valve 8 is installed on the second water injection pipe 5. The second water injection pipe 5 serves as a backup water injection pipeline. When a power outage occurs, the solenoid valve 7 cannot work, and the first water injection pipe 3 cannot be injected with water. The ball valve 8 is manually opened to inject water into the auxiliary water tank 4 from the second water injection pipe 5.

[0011] An electric control box 6 is installed on the end face of the auxiliary water tank 4, and a transformer 601 and a relay 602 are installed in the electric control box 6.

When the second liquid level sensor 10 detects that the water level has reached the highest, the solenoid valve 7 is closed and the water replenishment stops.
