The structure of the diversion tube is complex, and with the passage of time, it is easy to scale, making the tube diameter smaller and water replenishment slow; 5. Due to the limitation of the foaming process, the gap between the inner tank and the outer shell The dimensional error between the two will become larger, and the inner tank will be relatively jumpy. During long-term use, the sealing ring will be damaged or the diversion tube will be broken, resulting in water tank leakage; 6. The structure is unreasonable, and too many spare parts are used, resulting in product costs and subsequent maintenance costs. high. 7. In the environment of low water pressure or unstable water pressure, the water heater cannot work normally, etc. For example:

Invention content:

The purpose of the present invention is to provide a solar water heater that can overcome the disadvantages of the existing solar water heaters, such as easy failure of the supplementary water tank, complicated structure of the diversion tube, easy scaling, poor sealing effect, many parts, and easy leakage of the water tank, etc. The utility model relates to a solar water heater with an oblique diversion plate for a water tank.

In order to solve the above problems, the technical scheme adopted in the present invention is as follows:

The solar water heater with double water tanks with oblique diversion plates includes a water tank with an insulating layer, several vacuum heat collecting tubes inserted in the water tank, an intelligent controller, a sensor, a solenoid valve, a water pump and an auxiliary heating device, and is characterized in that: The inner tank of the water tank is divided into two sub-water tanks with a partition. The sub-water tank is a combination of a low-temperature cabin and a high-temperature cabin; Heating device and draft tube maintenance holes;

The baffle assembly is a component that is welded together with two baffles and a ring matching the diameter of the inner tank, and the baffle is equipped with an oblique diversion pipe that can circulate the hot water of the two water distribution tanks; the oblique guide The flow pipe is a straight pipe, so that the water in the adjacent water tank can flow quickly, and it is not easy to scale, and it is also easy to clean; the two partitions and the ring are welded into a partition assembly, which is more conducive to the precision of the dimensions between parts. It ensures the sealing performance between the parts and facilitates daily maintenance and replacement of parts such as the guide tube, which also improves the production efficiency.

After long-term practice, the present invention can reduce the temperature by 3-5° C. at night for 12 hours in winter in Guangxi under the state of being full of water, and has a good heat preservation effect.

The gaps between the partition board assemblies A are hollow or filled with insulation layers. Keep a certain distance between the partitions, and the temperature of hot water will not be directly transmitted to the adjacent water tanks, which ensures the thermal insulation performance of the hot water temperature.

The angle of inclination of the above-mentioned inclined diversion pipe of the partition is 10°-89°, the upper end of the inclined diversion pipe communicates with the hot water layer above the low-temperature chamber, and the lower end of the inclined diversion pipe communicates with the cold water layer below the high-temperature chamber. It regulates the trend of high inflow and low outflow of hot water in the process of replenishing water, making the separation of hot water and cold water more delicate, and making full use of hot water with maximum efficiency.

The intelligent controller described above is a combination of a temperature controller and a water level controller. The integrated control of water temperature and water level can reduce the cost of investing in the water supply tank, and at the same time, it can perform local rapid auxiliary heating for the high temperature cabin, saving auxiliary heating time and reducing auxiliary heating electricity costs.

The front of the entrance of the above-mentioned low-temperature cabin is provided with a water booster pump, and the water with a relatively slow flow rate is directly passed into the high-temperature cabin through an intelligent controller. Under the conditions of low tap water pressure, unstable water pressure or direct use of well water as a water source, adding a booster pump can press cold water into the water tank, which effectively improves the popularity of solar water heaters, and solar water heaters can be used as water storage tanks .

The above-mentioned water heater does not need to install a make-up water tank for water intake. Due to the adoption of automatic flow and intelligent control relying on hot and cold water, there is no need to use a replenishing water tank, which reduces the cost for users to purchase water heaters, and prevents the water heater from being unusable due to failure of the replenishing water tank.

The intelligent controller mentioned above can control the arbitrary height of the water level of the high temperature cabin. This function solves the problem that the conventional multi-tank solar water heater uses a replenishment tank to control the water level, and cold water enters the water heater at any time, causing cold water and hot water to mix at any time and causing the water temperature in the high temperature cabin to drop rapidly. Ensure that the water temperature will not drop when the user takes a bath.

Above-mentioned water tank clapboard top is provided with breathing hole, and water tank two ends are provided with the perforation that clears breathing orifice and diversion pipe by cleaning bar. It is convenient for users and maintenance personnel to clean the breathing holes and diversion pipes, reducing maintenance costs.

The above-mentioned clapboard breathing holes are installed with straight pipes. It can prevent the gas volume of the water tank from accumulating in the inner tank and causing deformation due to unsmooth exhaust.

The inner tank of the above-mentioned water heater tank is provided with a multi-purpose drain hole for maintenance and cleaning of the inclined draft pipe. It is convenient for users and maintenance personnel to discharge the dirt in the water tank and replace the guide pipe, thereby reducing the maintenance cost.

Advantages of the present invention:

After long-term practice, the present invention can reduce the temperature by 3-5°C at night for 12 hours in winter in Guangxi under the condition of being full of water. The heating water temperature can be set according to the user's water consumption. When encountering cloudy, rainy and snowy weather, the amount of hot water used for heating can be realized, so as to save electricity and reduce the auxiliary heating time. In addition, due to the automatic flow and intelligent control relying on hot and cold water, there is no need to use a supplementary water tank, which reduces the cost of purchasing a water heater for users, and prevents the water heater from being unusable due to failure of the supplementary water tank. By setting the lack of water filling mode, it can avoid the phenomenon that the water temperature of the high temperature cabin drops sharply when taking a bath while filling the water. The structure of the diversion tube is simple, the water can be replenished quickly, it is not easy to be scaled and blocked, and it is easy to clean, maintain and replace. Due to the use of a water pump to boost pressure, it can be used normally in areas with low water pressure or no tap water. The two kinds of partitions are used together to standardize the direction of high inflow and low outflow of hot water in the process of replenishing water, so that the separation of hot water and cold water is more delicate, and the hot water can be fully used with maximum efficiency. The low temperature cabin and the high temperature cabin are optimally connected through the partition As a whole, the exhaust pipe and the partition are ingeniously integrated, the structure is simple and reasonable, the overall appearance is elegant, and the cost is low, which is more conducive to popularization and application.
