However, the existing compartmentalized water heaters still have the following disadvantages: 1. The valve of the supplementary water tank is easy to be fouled and blocked; 2. It is impossible to quantitatively control the water level of the water tank; 3. Since the supplementary water tank is filled with water at any time, the hot water in the water tank is very fast Mixing with cold water causes the water temperature to drop rapidly; 4. 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.

Invention content:

The purpose of the present invention is to provide a kind of water heater that can overcome the deficiencies of the existing solar water heaters, such as easy failure of the supplementary water tank, complex structure of the diversion tube, easy scaling, poor sealing effect, many parts, and easy leakage of the water tank. The water tank is equipped with a step-type solar water heater with an exhaust gas diversion plate.

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

The step-type solar water heater without a supplementary water tank, exhaust and diversion plate, 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. It is characterized in that: the inner tank of the water tank is divided into two or more sub-water tanks by a partition A, a partition C and a partition assembly B, and the sub-water tanks are a combination of a low-temperature cabin and a high-temperature cabin, or a low-temperature cabin and a medium-temperature cabin Combination with high temperature cabin; low temperature cabin is provided with water inlet pipe and sewage hole, high temperature cabin or medium temperature cabin is provided with water outlet pipe, sensor, auxiliary heating device, diversion pipe maintenance hole and breathing pipe maintenance hole;

The partition A and the partition C keep a certain distance, and more than two-thirds of the two partitions are equipped with a draft tube and a breathing tube capable of circulating the hot water of the two sub-water tanks; the draft tube is A section of straight pipe enables the water in the adjacent water tank to flow quickly, and is not easy to scale and easy to clean; it is easy to manufacture and high in production efficiency.

The baffle assembly B is a component that is welded together with two baffles and a ring that match the diameter of the inner tank. The upper part of the gap between the two baffles is provided with a breathing hole and a guide tube. The gap between the two baffles is There is an exhaust hole at the bottom of the water tank; when the temperature of the hot water reaches a certain pressure, the hot air passes through the gap of the partition assembly B from the breathing channel and is discharged from the exhaust hole. The conventional lower exhaust pipe is replaced by making full use of the gap between the two partitions, while ensuring unobstructed exhaust and reducing the manufacturing cost of the water heater. 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 gap between the partition assembly A and the partition C is hollow or filled with an insulating layer. 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 above-mentioned diversion tubes of partition A and partition C are located at more than two-thirds of the two partitions, and the upper end of the diversion tube is connected to the hot water layer above the low-temperature cabin to ensure that what flows through the medium-temperature cabin is the low-temperature cabin. The hot water with the highest temperature makes the separation of hot water and cold water more delicate and makes full use of hot water.

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 booster water pump, and the water with a relatively slow flow rate is directly passed into the high-temperature cabin or the medium-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 high-temperature chamber is provided with the opening that clears breathing hole and draft tube by cleaning bar. It is convenient for users and maintenance personnel to clean the breathing holes and diversion pipes, reducing maintenance costs.

The partition A and partition C described above are provided with breathing tubes. It can prevent the gas volume of the water tank from accumulating in the inner tank and causing deformation due to unsmooth exhaust.

The above-mentioned breathing hole of the partition B communicates with the high temperature cabin or the medium temperature cabin. It can prevent the water tank from being deformed due to unsmooth exhaust.

The inner tank of the water heater tank described above is provided with a drain hole. It is convenient for users and maintenance personnel to regularly discharge the dirt in the water tank, which improves the cleanliness of hot water and prolongs the service life of the water tank.

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 partitions are used together to separate hot water and cold water more delicately, and make full use of hot water. The low-temperature cabin, the medium-temperature cabin and the high-temperature cabin are connected into a whole through optimization of the partition, and the exhaust pipe and the partition are integrated ingeniously. The structure is simple and reasonable, the overall appearance is elegant, and the cost is low, which is more conducive to popularization and application.
