Description

Technical Field

[0001] The utility model relates to the technical field of solar water tanks, in particular to an automatic water-replenishing constant-temperature 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

[0003] In view of the problems existing in the prior art, the utility model discloses an automatic water-replenishing constant-temperature solar water tank, the technical scheme adopted is that an auxiliary water tank is fixedly connected to one end of the main water tank through an upper connecting pipe and a lower connecting pipe, the top of the inner cavity of the auxiliary water tank is lower than the top of the inner cavity of the main water tank, thereby ensuring that there is a certain space in the inner cavity of the main water tank to store the steam generated by hot water, the main water tank is connected to the auxiliary water tank through the upper connecting pipe and the lower connecting pipe, the top of the auxiliary water tank is connected to the water inlet pipe, the water inlet pipe is installed on the auxiliary water tank, a liquid level sensor is installed in the inner cavity of the auxiliary water tank, the liquid level sensor is electrically connected to the solenoid valve, the liquid level sensor uses a float liquid level sensor, the water level in the auxiliary water tank is detected by the liquid level sensor, when the lowest water level is reached, the solenoid valve is opened, water is added to the auxiliary water tank through the water inlet pipe, the injected water will enter the main water tank through the upper connecting pipe and the lower connecting pipe, when the water level reaches the highest, the solenoid valve is closed, and the water replenishment is stopped.

[0004] As a preferred solution of the utility model, the auxiliary water tank includes a water tank liner, the top of the water tank liner is open and sealed with a water tank cover, the outside of the water tank liner is fixedly connected to a water tank shell, and an insulation layer is filled between the water tank liner and the water tank shell. The insulation layer is made of insulation materials such as insulation foam and rock wool, so as to ensure the water temperature of the hot water in the water tank liner and avoid excessive heat dissipation.

[0005] The beneficial effects of the utility model are as follows: an auxiliary water tank is added to the original main water tank, a water inlet pipe is connected to the auxiliary water tank for connecting to a water supply pipe, and a solenoid valve is installed on the water inlet pipe. The water level in the auxiliary water tank is detected by a liquid level sensor, so that the solenoid valve controls the water inlet pipe to replenish water, 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 constant temperature effect of the hot water used, and avoiding the situation where the hot water cannot be used due to water replenishment when there is a large amount of hot water surplus. The auxiliary water tank adopts a heat preservation design to avoid heat loss of hot water. At the same time, the auxiliary water tank can also increase the water storage capacity of the main water tank. BRIEF DESCRIPTION OF THE DRAWINGS

[0009] Example 1

[0010] like Figure 1 to Figure 2As shown, the utility model is an automatic water-replenishing constant-temperature solar water tank, in which an auxiliary water tank 4 is fixedly connected to one end of a main water tank 1 through an upper connecting pipe 2 and a lower connecting pipe 3, the auxiliary water tank 4 includes a water tank liner 402, the top of the water tank liner 402 is open and sealed with a water tank cover 401, the outer side of the water tank liner 402 is fixedly connected to a water tank shell 404, and an insulation layer 403 is filled between the water tank liner 402 and the water tank shell 404, and the insulation layer 403 is made of insulation materials such as insulation foam and rock wool, so as to ensure the water temperature of the hot water in the water tank liner 402 and avoid excessive heat dissipation. The top of the inner cavity of the water tank liner 402 in the auxiliary water tank 4 is lower than the top of the inner cavity of the main water tank 1, so as to ensure that there is a certain space in the inner cavity of the main water tank 1 to store the steam generated by hot water. The main water tank 1 is connected to the auxiliary water tank 4 through the upper connecting pipe 2 and the lower connecting pipe 3. The top of the water tank liner 402 of the auxiliary water tank 4 is connected to the water inlet pipe 5, and the water inlet pipe 5 is installed on the solenoid valve 6. A liquid level sensor 7 is installed in the inner cavity of the auxiliary water tank 4. The liquid level sensor 7 is electrically connected to the solenoid valve 6. The liquid level sensor 7 uses a float liquid level sensor. The water level in the water tank liner 402 of the auxiliary water tank 4 is detected by the liquid level sensor 7. When the lowest water level is reached, the solenoid valve 6 is opened, and water is added to the auxiliary water tank 4 through the water inlet pipe 5. The injected water will enter the main water tank 1 through the upper connecting pipe 2 and the lower connecting pipe 3. When the water level reaches the highest, the solenoid valve 6 is closed to stop replenishing water. Refilling water when the water level is at the lowest level can ensure the constant temperature of the hot water in the main water tank 1, and the hot water can be fully used.
