Description

Wall-mounted automatic solar water heater

Technical field:

The utility model relates to a household solar water heater, in particular to a wall-mounted solar water heater which does not need manual water filling.

Background technique:

At present, the commonly used domestic solar water heaters include water supply valves, water outlet valves, dual-purpose pipes, overflow pipes, heat preservation water tanks, heat collectors and installation frames. , a refraction plate and a lower bracket, the open end of the heat collecting tube is upwards, and is evenly installed on the heat preservation water tank through the sealing ring, the inner cavity of the heat collection tube communicates with the heat preservation water tank, and the closed end of the heat collection tube is supported on the lower bracket, refracting The plate is set on the back of the heat collecting tube; the mounting frame is a frame structure, and the heat preservation water tank and the heat collector are fixed on the mounting frame; the dual-purpose pipe is connected to the inlet and outlet of one end of the heat preservation water tank, and the overflow pipe is set at the other end of the heat preservation water tank. And be in the top position close to the thermal insulation water tank, one end of the water supply valve communicates with the running water pipe, the other end communicates with the dual-purpose pipe, one end of the water outlet valve communicates with the dual-purpose pipe, and the other end links to each other with the shower head of the shower. The collectors are at an angle to the horizontal to get more light and get more heat. Such solar water heaters are usually installed on the roof. The method of use is: in the state of water supply, close the water outlet valve, open the water supply valve, when the overflow pipe comes out, it means that the insulated water tank has been filled with water, and the water supply valve must be closed immediately, and someone must take care of this process; in use state, close Fill the water valve and open the water outlet valve.

There are two problems in the use of existing solar water heaters. The one is that it is inconvenient to use. The water supply valve and the water outlet valve must be correctly controlled every time it is used. The whole process must be carried out under the care of people, otherwise it will not only cause The loss of water will even flood the whole house and bring troubles to people. The second is that the users of solar water heaters are limited by the floors. For high-rise buildings, due to the limited roof area, it is impossible to install more solar water heaters to meet the needs of all residents. Because solar water heaters have irreplaceable advantages in environmental protection and energy saving, they are widely used, but because of their cumbersome use, limited installation places, and the need for people to take care of them during use, they cannot meet the requirements of modern people's lives. People are in urgent need of a wall-mounted fully automatic solar water heater. This solar water heater can be installed freely no matter which floor you live in. It does not need manual water supply during use. When not in use, turn off the tap and leave the water, which completely eliminates people's troubles in using solar water heaters.

Utility model content:

The purpose of the utility model is to provide a wall-mounted fully automatic solar water heater.

The technical scheme that the utility model takes is:

The wall-mounted full-automatic solar water heater of the utility model includes a thermal insulation water tank, a support and a heat collection tube. The inner cavity of the heat preservation water tank communicates with the inner cavity of the heat preservation water tank, and the closed end of the heat collection tube is supported on the bracket. The water pipe is connected, and the other end is connected with the water outlet pipe; the energy-absorbing liquid is filled in the thermal insulation water tank, and the heat exchange device is soaked in the energy-absorbing liquid.

The heat exchange device is composed of a water inlet distributor, a water outlet distributor and a number of heat-conducting pipes. The heat-conducting pipes are arranged between the water inlet distributor and the water outlet distributor. The water distributor communicates with the water inlet pipe, and the water outlet distributor communicates with the water outlet pipe.

The heat collecting tube is installed vertically, with the open end upwards, and the thermal insulation water tank is arranged above the heat collecting tube.

The heat collecting tube is installed horizontally, and the heat preservation water tank is arranged on one side of the open end of the heat collecting tube.

The heat collecting pipes are horizontally arranged symmetrically to the heat preservation water tank, and the open ends of the heat collection pipes face the heat preservation water tank.

The heat-conducting pipe is a tubular heat-conducting pipe or a sheet-shaped heat-conducting pipe; the energy-absorbing liquid is water or antifreeze emulsion.

Because the solar support is designed as a wall support, and the heat collecting pipe and the heat preservation water tank are fixed on the wall support, this solar water heater can be installed on the wall below the window without being restricted by floors. A heat exchange device is added in the heat preservation water tank. The heat preservation water tank is filled with stagnant energy-absorbing liquid. The heat absorbed by the heat collecting tube is stored in the energy-absorbing liquid. The heat exchange device is soaked in the energy-absorbing liquid. One end is connected to the tap water pipe, and the other end is connected to the hot water faucet. When people use the solar water heater, the tap water will flow into the heat exchange device from the water inlet pipe when people use the solar water heater. Give the water flowing through the heat exchange device, so that the hot water is released from the hot water faucet, and you can leave after turning off the hot water faucet after use, which completely solves the troubles of people using solar water heaters. Water can also be the antifreeze emulsion or other high-boiling point aqueous solution injected into the water tank of the car. Its function is to absorb and store the heat energy collected by the heat collecting tube. The energy absorbing liquid is the heat source for the heat exchange device. The hot water released by this kind of solar energy is fresh running water, not the overnight water stored in the thermal water tank for a long time. Compared with the existing solar energy, it is more convenient and hygienic to use, and it is an ideal substitute for the existing solar water heater.
