After the water is heated to a certain temperature, the water does not need to be heated at this time, and the temperature of the water in the insulated water tank is detected by the temperature control unlocking structure. When the water in the insulated water tank is heated to a certain temperature, the shielding structure is opened by the temperature control unlocking structure, and several groups of vacuum tubes are shielded by the shielding structure. At this time, the sun cannot shine on the reflective plate, so the water is no longer heated, reducing waste.

[0013] By adopting the above technical solution, when the water in the insulated water tank is heated to a certain temperature, the water temperature in the insulated water tank is detected by relying on the heat-conducting rod.

[0028] In order to prevent the water in the solar water heater from being heated continuously after the heating is completed, so as to prevent the water from being heated continuously and wasted, as an embodiment of the utility model, Figure 1-4 As shown, a solar water heater for hybrid utilization of solar energy described in the utility model comprises a main frame 1, a heat preservation water tank 2 is arranged on the top of the main frame 1, a plurality of groups of vacuum tubes 3 are arranged inside the main frame 1, one end of the plurality of groups of vacuum tubes 3 passes through the heat preservation water tank 2 and is located inside the heat preservation water tank 2, a reflector is fixedly connected to one side of the main frame 1 close to the plurality of groups of vacuum tubes 3, and the reflector is located below the plurality of groups of vacuum tubes 3;

[0029] It is characterized in that a shielding structure is provided on the side of several groups of vacuum tubes 3 away from the reflective plate, and a temperature control unlocking structure is provided inside the thermal insulation water tank 2. The temperature control unlocking structure is used to unlock the shielding structure at high temperature, and the shielding structure is used to shield the vacuum tubes 3.

[0030] When in use, water is transported to the insulated water tank 2, and the vacuum tube 3 is heated by the sun shining on the reflective plate. The water in the insulated water tank 2 is heated by the vacuum tube 3. After the water is heated to a certain temperature, the water does not need to be heated at this time. The temperature of the water in the insulated water tank 2 is detected by the temperature control unlocking structure. When the water in the insulated water tank 2 is heated to a certain temperature, the shielding structure is opened by the temperature control unlocking structure. The shielding structure is used to shield several groups of vacuum tubes 3. At this time, the sun cannot shine on the reflective plate, so the water is no longer heated, reducing waste.

[0031] In order to shield the vacuum tube 3, for example, Figure 1-4 As shown, the utility model also includes that the shielding structure includes a flexible solar panel 4 arranged above the vacuum tube 3, the flexible solar panel 4 is initially wound on the rotating shaft, both ends of the rotating shaft are rotatably connected to the fixing sleeve 5, and the fixing sleeve 5 is fixedly connected to both sides of the thermal insulation water tank 2 through the fixing rod 6;

[0032] The main frame 1 is provided with two groups of inclined sliding rods 7, both ends of the sliding rods 7 are fixedly connected to one side of the main frame 1, and sliding blocks 8 are slidably connected to the sliding rods 7, and one side of the two groups of sliding blocks 8 are respectively fixedly connected to the corners of the flexible solar cell panels 4; the sliding blocks 8 are magnetic-friendly, and the temperature control unlocking structure is magnetically adsorbed to one side of the sliding block 8.

[0033] When in use, by relying on the magnetic adsorption of the temperature control unlocking structure and the sliding block 8, when the water in the thermal insulation water tank 2 is heated to a certain temperature, the temperature control unlocking structure is no longer magnetically adsorbed to the sliding block 8, and the sliding block 8 is connected to the sliding rod 7 by sliding, so that the sliding block 8 moves downward, and the sliding block 8 drives the flexible solar panel 4 to unfold when moving downward, so that the vacuum tube 3 is shielded by the flexible solar panel 4 to prevent the water in the thermal insulation water tank 2 from continuing to be heated;

[0034] At the same time, the flexible solar cell panel 4 can convert solar energy into electrical energy, further improving the utilization rate of solar energy;

[0035] It should be pointed out that after the sliding block 8 described in the utility model is no longer magnetically adsorbed to the temperature control unlocking structure, the sliding block 8 can drive the flexible battery panel to move downward and unfold, thereby no longer heating the water in the thermal insulation water tank 2.

[0036] In order to facilitate the detection of the water in the thermal insulation water tank 2, for example, Figure 2 , 3 , Figure 4 As shown, the utility model also includes that the temperature control unlocking structure includes a heat-conducting rod 11, one end of the heat-conducting rod 11 passes through the insulated water tank 2 and is located in the insulated water tank 2, and the lower end of the heat-conducting rod 11 is connected to a temperature-sensitive magnet 9, and the temperature-sensitive magnet 9 is magnetically adsorbed to the side of the sliding block 8 away from the flexible solar panel 4.

[0037] During use, when the water in the insulated water tank 2 is heated to a certain temperature, the water temperature in the insulated water tank 2 is detected by the heat conducting rod 11. When the water reaches a certain temperature, the magnetic effect of the temperature sensing magnet 9 disappears, so that the temperature sensing magnet 9 is no longer magnetically adsorbed to the sliding block 8, thereby shielding several groups of vacuum tubes 3 through the flexible solar cell panel 4, and the water in the insulated water tank 2 is no longer heated.

[0038] For example, Figure 1 As shown, the utility model also includes that one end of the rotating shaft is fixedly connected to a handle 10.

[0039] When in use, the handle 10 can be turned to drive the shaft to rotate, so that the flexible solar panel 4 can be rolled up for the next use, thereby further improving the convenience of use.

[0040] Exemplarily, the utility model also includes that the flexible solar panel 4 is connected to a photovoltaic controller via a line.

[0041] When in use, after the flexible solar panel 4 is unfolded, the flexible solar panel 4 and the photovoltaic controller can convert solar energy into electrical energy, thereby further improving the utilization of solar energy.

[0042] When the utility model is in use, water is transported to the insulated water tank 2, and the vacuum tube 3 is heated by the sun irradiating the reflective plate, and the water in the insulated water tank 2 is heated by the vacuum tube 3. After the water is heated to a certain temperature, the water does not need to be heated at this time, and the temperature of the water in the insulated water tank 2 is detected by the temperature control unlocking structure. When the water in the insulated water tank 2 is heated to a certain temperature;

[0043] The water temperature in the heat-insulating water tank 2 is detected by the heat-conducting rod 11. When the water reaches a certain temperature, the magnetic effect of the temperature-sensitive magnet 9 disappears, so that the temperature-sensitive magnet 9 is no longer magnetically adsorbed to the sliding block 8.

[0044] By relying on the sliding connection between the sliding block 8 and the sliding rod 7, the sliding block 8 moves downward, and when the sliding block 8 moves downward, the flexible solar panel 4 is driven to unfold, so that the vacuum tube 3 is shielded by the flexible solar panel 4 to prevent the water in the thermal insulation water tank 2 from continuing to be heated;

[0045] After the flexible solar panel 4 is unfolded, the solar energy can be converted into electrical energy by means of the flexible solar panel 4 and the photovoltaic controller, thereby further improving the utilization of solar energy.
