Description

Technical Field

[0001] This utility model relates to the field of energy-saving technology, specifically to a combined solar and air-source water heater. Background Technology

[0002] Solar and air source combined water heaters are innovative energy utilization devices that combine the advantages of two clean energy sources: solar and air source, providing users with efficient, environmentally friendly, and multifunctional hot water solutions.

[0003] Solar and air source combined water heaters heat water using solar energy on sunny days. On cloudy or rainy days, when solar radiation is insufficient and the water temperature is not up to standard, air source heat pumps provide auxiliary heating. Whether the air source heating device is activated for auxiliary heating during operation is generally monitored by a water temperature sensor. However, this monitoring method is relatively simple. When the water temperature sensor malfunctions or fails for other reasons, the device will not be able to automatically activate the air source auxiliary heating on cloudy or rainy days, which is unreliable. Therefore, based on the above problems, a solar and air source combined water heater is proposed. Utility Model Content

[0004] The purpose of this utility model is to provide a solar and air source combined water heater to solve the problem that the existing solar and air source combined water heaters have a relatively simple monitoring method. When the water temperature sensor malfunctions or has other problems, the device will not be able to automatically provide auxiliary heating on cloudy or rainy days, resulting in unreliability.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

A monitoring unit is installed between the left end of the return pipe and the solar water heater. The monitoring unit includes a water passage pipe connected to the return pipe and the solar water heater. A casing is installed at the water passage pipe, and supports are fixedly connected to the upper left and right sides of the casing. A set of supports is fixedly connected...

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] In this invention, the water tank, solar water heater, monitoring unit, and water temperature sensor are designed to create a water circulation system. The solar water heater heats the circulating water using solar energy, while the monitoring unit and water temperature sensor monitor the water temperature in different ways. If the temperature is below the required level, the air source heat pump water heater is activated for auxiliary heating. This allows for multiple monitoring methods to determine whether the combined solar and air source heat pump water heater needs auxiliary heating, improving the reliability of the equipment. It also solves the problem that existing combined solar and air source heat pump water heaters have a relatively simple monitoring method, and when the water temperature sensor malfunctions or fails for other reasons, the equipment cannot automatically provide auxiliary heating on cloudy or rainy days, leading to unreliability.

[0026] Please see Figure 1-6 This utility model provides a technical solution:

[0027] A combined solar and air source water heater includes a water tank 1, a monitoring unit 4, a control box 5, and a water temperature sensor 6. The water tank 1 includes a tank body 11. An air source water heater 3 is connected to the right side of the tank body 11. A water supply pipe 12 is connected to the front side of the tank body 11. A solar water heater 2 is connected to the left end of the water supply pipe 12. A return water pipe 14 is connected to the rear side of the tank body 11. The monitoring unit 4 is installed between the left end of the return water pipe 14 and the solar water heater 2. The monitoring unit 4 includes a water pipe 401 that connects to the return water pipe 14 and the solar water heater 2. A casing 402 is installed at the water pipe 401. Supports 403 are fixedly connected to the upper left and right sides of the casing 402. A conduit 404 is fixedly connected between a group of support frames 403. A track groove 405 is provided on the curved surface of the guide tube 404. A support block 406 located below the track groove 405 is fixedly connected to the outer curved surface of the guide tube 404. A contact button 407 is installed on the upper side of the support block 406. A guide block 408 is slidably connected to the inner side of the housing 402. A pressure block 409 slidably connected to the track groove 405 is fixedly connected to the outer side of the guide block 408. A connecting rod 410 is fixedly connected to the lower side of the guide block 408. A float 411 located inside the housing 402 is fixedly connected to the lower end of the connecting rod 410. A set of multiple exhaust ports 412 are provided on the outer curved surface of the float 411. A rubber baffle 413 is fixedly connected to the upper side of the float 411. A control box 5 is installed on the front side of the housing 11. A water temperature sensor 6 is installed at the hole of the housing 11.

[0028] The air source water heater 3 consists of a main unit, a return pipe, an inlet pipe, and a pump body. The control box 5 is electrically connected to the water pump 13, and also electrically connected to the main unit and pump body of the air source water heater 3. This connection allows the control box 5 to control the operation of the air source water heater 3. The water temperature sensor 6 is electrically connected to the control box 5, allowing the water temperature sensor 6 to control the operation of the air source water heater 3 through the control box 5. The contact button 407 is electrically connected to the control box 5. This configuration allows the contact button 407 to control the air source water heater 3 via the control box 5; the float plate 411 is positioned above the water pipe 401, allowing the steam from the high-temperature water flowing through the water pipe 401 to push the float plate 411 upwards. The outer curved surface of the float plate 411 fits against the inner wall of the casing 402. The rubber baffle 413 is positioned above the exhaust port 412, enhancing the upward thrust of the steam; the left end of the pressure block 409 protrudes from the rail groove 405. 9 is positioned above the contact button 407, with the pressure block 409 fitting against it. This arrangement allows the pressure block 409, guided by the guide groove 405, to activate the contact button 407. A water supply pipe is connected to the front curved surface of the housing 11, allowing users to connect an external pipe to supply water to the housing 11. A water supply pipe is also connected to the front curved surface of the housing 11, enabling the housing 11 to be connected to an external pipe for high-temperature water supply. The upper side of the conduit 404 is fixedly connected to... The cover of the conduit 404 has a diameter larger than that of the housing 402. The cover of the conduit 404 is located on the upper side of the housing 402. This design prevents rainwater from falling into the housing 402 and thus prevents rainwater from accumulating on the upper side of the floating plate 411. The lower outer side of the conduit 404 is fixedly connected to a stop 414 located on the upper side of the floating plate 411. This design allows the stop 414 to stop and limit the upward movement of the floating plate 411, ensuring that the floating plate 411 is always inside the housing 402.

[0029] Workflow: The operation of the combined solar and air source water heater is as follows: Solar heating operation steps, precautions, and control of the following electrical equipment are all controlled through control box 5. Start water pump 13 and solar water heater 2. Water is drawn from tank 11 through water pump 13 and water pipe 12 and delivered to solar water heater 2 for heating. After heating, the hot water flows through the water pipe 401 of monitoring unit 4 and returns to tank 11 through return pipe 14 to complete the heating. The above steps complete the solar heating operation. Monitoring operation steps: When the solar radiation is insufficient in cloudy or rainy weather and the water temperature is not up to standard, the air source water heater 3 can be started to provide air source auxiliary heating of the water in tank 11 through two monitoring methods. The first method is to detect the water temperature in tank 11 through water temperature sensor 6. If the water temperature in tank 11 is lower than the threshold, it indicates that the solar radiation is insufficient and auxiliary heating is required. Therefore, a control signal is sent to control box 5. The second method is that when the water heated by solar water heater 2 passes through water pipe 401, the water vapor will pass through casing 4. 02. If the water temperature is high and there is sufficient steam, the steam will push the float 411, connecting rod 410, guide block 408, and pressure block 409 upwards, preventing the pressure block 409 from contacting the contact button 407. At the same time, excessive steam will deform the rubber baffle 413 and discharge it from the exhaust port 412. If the water temperature is low and there is insufficient steam, the pressure block 409 will move downwards to reset, squeezing the contact button 407 and sending a control signal to the control box 5. Through the above steps, the monitoring operation is completed, and whether the solar and air source combined water heater needs air source auxiliary heating can be monitored and started in multiple ways, improving the reliability of the equipment. Air source auxiliary heating operation steps: After receiving the control signal, the control box 5 will start the pump and main unit of the air source water heater 3. The warm water in the tank 11 can be transported to the main unit of the air source water heater 3 for air source auxiliary heating through the pump and the liquid inlet pipe. After heating, it is transported back to the tank 11 through the liquid return pipe of the air source water heater 3. Through the above steps, the air source auxiliary heating operation of the warm water is completed.
