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 a photovoltaic-assisted heating water heater, including: an insulation barrel 1, a vacuum insulation panel 4 arranged in the insulation barrel 1 and dividing the insulation barrel 1 into a first heating zone 2 and a second heating zone 3, a photovoltaic heating system arranged in the first heating zone 2, an electric heating system arranged in the second heating zone 3, upper and lower water pipelines arranged on the insulation barrel 1, and a controller for controlling the operation of the water heater; a heat conduction pipe 5 connecting the first heating zone 2 and the second heating zone 3 is arranged on the vacuum insulation panel 4, and a connecting pipe 6 connecting the first heating zone 2 and the second heating zone 3 is arranged at the upper end of the vacuum insulation panel 4. The vacuum insulation board 4 separates the first heating zone 2 and the second heating zone 3. In this embodiment, the capacity of the first heating zone 2 is smaller than that of the second heating zone 3. The photovoltaic heating system can preferentially heat the first heating zone 2 to raise the water temperature. The heat pipe 5 transfers heat between the first heating zone 2 and the second heating zone 3. The heat energy of the first heating zone 2 comes from the photovoltaic system, which is environmentally friendly and energy-saving. The heat pipe 5 can transfer heat energy to the water in the second heating zone 3. The length of the heat pipe 5 in the first heating zone 2 is shorter than that in the second heating zone 3. In this way, the efficiency of heat transfer from the second heating zone 3 to the first heating zone 2 is lower than the efficiency of heat transfer from the first heating zone 2 to the second heating zone 3, which can save electricity. The connecting pipe 6 balances the air pressure of the first heating zone 2 and the second heating zone 3. The heat pipe 5 preferably uses a floor heating pipe. The insulation barrel 1 is an existing water heater insulation barrel.

The photovoltaic heating system comprises a first electric heating rod 7 arranged in the first heating zone 2, and a photovoltaic panel 8 electrically connected to the first electric heating rod 7. The photovoltaic panel 8 is arranged in a place convenient for receiving light, and the first electric heating rod 7 is a 12V-60V DC heating tube.

The electric heating system is a second electric heating rod 9 electrically connected to the controller. The controller controls the second electric heating rod 9 to heat the water in the second heating area 3.

A first temperature sensor 10 electrically connected to the controller is provided in the first heating zone 2, and a second temperature sensor 11 electrically connected to the controller is provided in the second heating zone 3. The first temperature sensor 10 detects the water temperature in the first heating zone 2 and displays it on the control panel of the controller, and the second temperature sensor 11 detects the water temperature in the second heating zone 3 and displays it on the control panel of the controller.

The upper and lower water pipes include an upper water pipe 12 disposed on one side of the heat preservation bucket 1, a first lower water pipe 13 disposed at the bottom of the first heating zone 2, and a second lower water pipe 14 disposed at the bottom of the second heating zone 3. The upper and lower water pipes also include a main lower water pipe 15, and the first lower water pipe 13, the second lower water pipe 14, and the main lower water pipe 15 are connected by a tee pipe 16. The upper water pipe 12 is connected to a positive pressure water source, and opening the positive pressure water source can replenish water for the heat preservation bucket 1. The main lower water pipe 15 combines the main lower water pipe 15 and the second lower water pipe 14 together to save pipes.

The first downpipe 13 is provided with a first solenoid valve 17, the second downpipe 14 is provided with a second solenoid valve 18, the main downpipe 15 is provided with a switch 19 for triggering the first solenoid valve 17 or the second solenoid valve 18, and the switch 19 is electrically connected to the controller. The switch 19 can be a touch sensor, which is electrically connected to the controller, and the switch 19 can also be a button switch; the controller compares the temperatures detected by the first temperature sensor 10 and the second temperature sensor 11, and opens the first solenoid valve 17 when the temperature of the first heating zone 2 is high, and opens the second solenoid valve 18 when the temperature of the second heating zone 3 is high. In addition, a ball valve should be provided on the main downpipe 15 to adjust the flow of hot water, so as to facilitate the mixing of hot water and cold water.

The water supply pipe 12 is provided with a third solenoid valve 20, and the third solenoid valve 20 is electrically connected to the controller. The third solenoid valve 20 can use the controller control panel to achieve water replenishment of the thermal insulation barrel 1.

The heat preservation barrel 1 is provided with a liquid level sensor 21, and the liquid level sensor 21 is electrically connected to the controller. The liquid level sensor 21 detects the water level in the heat preservation barrel 1. When the water level is lower than the set value, the controller triggers the third solenoid valve 20 to automatically fill the water, so as to prevent the first electric heating rod 7 and the second electric heating rod 9 from drying out.

The interior of the heat preservation barrel 1 is vertically provided with an exhaust pipe 22 penetrating from the bottom of the heat preservation barrel 1. The exhaust pipe 22 is hidden in the heat preservation barrel 1 to maintain the internal and external air pressure balance of the heat preservation barrel 1, and can also reduce the heat loss rate of water.

The control can be Siemens S7-200 PLC, and the YAMAHA YCT151B integrated temperature controller can be selected.

When the photovoltaic auxiliary heating water heater of the utility model is used:

The thermos barrel 1 can be set indoors or outdoors, and the photovoltaic panel 8 is set at a position conducive to receiving light. The photovoltaic panel 8 is used daily to power the first electric heating rod 7 to heat hot water. When the hot water temperature is not high enough, the controller is used to start the second electric heating rod 9 for additional heating.
