Technical Field

The utility model relates to the technical field of solar water heaters, in particular to an electrically assisted heating solar water heater.

Background technique

Solar water heaters are heating devices that convert sunlight into heat energy, heating water from low temperature to high temperature to meet people's hot water needs in life and production. In the solar heat preservation barrel, low-temperature water sinks into the vacuum collector tube for heating, and hot water floats up in the heat preservation barrel for insulation. Through the above cycle, cold water is heated into hot water. Therefore, the water in the heat preservation barrel has a high temperature on the upper layer and a low temperature on the lower layer. The water pipe down the heat preservation barrel is set at the bottom of the heat preservation barrel, resulting in the water in the heat preservation barrel not being at the highest temperature, and uneven hot and cold water will occur during use.

In summary, the technical problems to be solved by the present invention are:

Detailed ways

The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

Please refer to Figures 1 and 2. This embodiment provides an electrically assisted heating solar water heater, including: an insulation barrel 1, a first vacuum insulation board 3 vertically arranged in the insulation barrel 1 and separating a water inlet bin 2, a second vacuum insulation board 6 vertically arranged in the insulation barrel 1 and separating a medium temperature bin 4 and a high temperature bin 5, a first heating barrel 7 inclined downwardly arranged on the side wall of the medium temperature bin 4, a plurality of first vacuum heat collecting tubes 8 inclined downwardly arranged on the first heating barrel 7, a second heating barrel 9 inclined downwardly arranged on the side wall of the high temperature bin 5, a plurality of second vacuum heat collecting tubes 10 inclined downwardly arranged on the second heating barrel 9, and an electric heating device 11 arranged in the high temperature bin 5; the water inlet bin 2 is connected to the medium temperature bin 4, the medium temperature bin 4 is connected to the high temperature bin 5, the water inlet bin 2 is provided with a water inlet pipe 21, and the high temperature bin 5 is provided with a downpipe 22. The insulation barrel 1 is divided into a water inlet bin 2, a medium temperature bin 4, and a high temperature bin 5. The water between the three bins is one-way connected. The medium temperature bin 4 is purely heated by the vacuum collector tube. The hot water enters the high temperature bin 5 through the second one-way valve 18. If the water temperature is insufficient, the electric heating device 11 is started to heat the hot water in the high temperature bin 5. The hot water in the high temperature bin 5 will not flow back into the medium temperature bin 4. Not heating the whole barrel of water will save electricity. The first heating barrel 7 and the second heating barrel 9 are set below the medium temperature bin 4 and the high temperature bin 5 of the insulation barrel 1. The high temperature water floats in the insulation barrel 1 to keep it warm, and the lower temperature water is heated in the first heating barrel 7 and the second heating barrel 9 and the vacuum collector tube. The downpipe 22 directly uses the water in the insulation barrel 1 to solve the problem of uneven hot and cold water.

The first heating barrel 7 is provided with a plurality of first connecting pipes 12 connected to the medium temperature chamber 4. The first heating barrel 7 has a heat preservation function, and the first connecting pipes 12 allow the medium temperature chamber 4 and the first heating barrel 7 to exchange cold and hot water.

The second heating barrel 9 is provided with a plurality of second connecting pipes 13 connected to the high temperature chamber 5. The second heating barrel 9 also has a heat preservation function, and the second connecting pipes 13 allow the high temperature chamber 5 and the first heating barrel 7 to exchange cold and hot water.

The electric heating device 11 includes an electric heater arranged in the high temperature warehouse 5, a controller electrically connected to the electric heater, and a temperature sensor 23 arranged in the high temperature warehouse 5, wherein the temperature sensor 23 is electrically connected to the controller. The controller can be a STM32 single chip microcomputer with a display module, and the temperature sensor 23 displays the hot water temperature in the high temperature warehouse 5, and the user starts the electric heater to heat the hot water through the controller. In addition, the controller can also use the OFF/ON control method to control the electric heater, so that the water temperature of the high temperature warehouse 5 is in a stable range, so that the water in the high temperature warehouse 5 does not decrease in temperature due to mixing with water of a lower temperature. Specifically, the target water temperature value is set by the controller, and the temperature sensor 23 collects the actual water temperature value and compares it with the target water temperature value. If the actual water temperature value is lower than the target water temperature value, the electric heater is started to increase the water temperature, and if the actual water temperature value is higher than the target water temperature value, the electric heater is turned off to stop heating the water. The electric heater can be an infrared carbon fiber heating tube, an electric heating tube, an electric heating rod, etc.

The water inlet pipe 21 is provided with a float valve 14 located in the water inlet bin 2. As a matter of course, the water inlet pipe 21 is connected to a positive pressure water source, and the float valve 14 can maintain the water level in the insulation bucket 1.

The first vacuum insulation panel 3 is provided with a first vent pipe 15, the first vacuum insulation panel 3 is provided with a first one-way valve 17 leading from the water inlet tank 2 to the medium temperature tank 4, the second vacuum insulation panel 6 is provided with a second vent pipe 16, and the second vacuum insulation panel 6 is provided with a second one-way valve 18 leading from the medium temperature tank 4 to the high temperature tank 5. The first one-way valve 17 prevents the hot water in the medium temperature tank 4 from flowing back into the water inlet tank 2 and mixing with the cold water. The second one-way valve 18 prevents the hot water in the high temperature tank 5 from flowing back into the medium temperature water tank, allowing the electric heater to concentrate its power to heat the water in the high temperature tank 5. The first vent pipe 15 and the second vent pipe 16 are located above the water level to maintain the air pressure balance between the three tanks.

An exhaust pipe 19 is vertically arranged in the heat preservation barrel 1 and extends from the bottom of the heat preservation barrel 1. The built-in exhaust pipe 19 can reduce the loss of heat through the exhaust pipe 19, and the hidden exhaust pipe 19 can also avoid breaking and blocking caused by external force.

The solar water heater with electric auxiliary heating is also provided with a bracket 20 to support the heat preservation barrel 1 , the first heating barrel 7 , the second heating barrel 9 , the first vacuum heat collecting tube 7 , and the second vacuum heat collecting tube 8 .

When the solar water heater with electric auxiliary heating of the utility model is used:

Water enters the water inlet tank 2 from the water inlet pipe 21, enters the medium temperature tank 4 through the first one-way valve 17, and enters the high temperature tank 5 through the second one-way valve 18. When the water level rises to the highest water level, the float valve 14 closes the water inlet pipe 21, the first vacuum heat collecting tube 8 heats the water in the medium temperature tank 4, and the second vacuum heat collecting tube 10 heats the water in the high temperature tank 5. As the solar energy heating time increases, the water temperature gradually rises, and the water with the highest temperature will float in the insulation barrel 1 and be available at any time; when the heating effect of the first vacuum heat collecting tube and the second vacuum heat collecting tube 10 is not good or too much water is used, the electric heater can be enabled to quickly heat the water in the high temperature tank 5.
