Description

A kind of apparatus for heating water by solar energy

The utility model belongs to household appliance technical field.

The utility model is applied to need in the daily life to use the occasion of hot water.

Solar water heater is a kind of household utensils that utilize solar energy.Advantages such as safe, pollution-free, convenient use that solar energy has.Use the solar water heater of solar energy to be subjected to user's welcome deeply.The solar water heater of existing similar techniques has solar cooker heated type and heat collecting type.The solar water heater of solar cooker heated type will heat the purpose that reaches hot water to water container behind the solar light focusing during use.The solar water heater of solar cooker heated type is subjected to the restriction of hours of daylight when having use, needs special messenger's nurse, safety and defective inadequately easily.The solar water heater of heat collecting type utilizes solar collector under the condition that sunlight shines, and the heat that solar light irradiation is produced conducts to the water in the solar water heater water tank and makes its intensification reach the purpose of hot water.The material that the heat collection type solar water heater exist to use is subjected to the influence of installation environment and mounting means easily and makes energy loss, need be installed in the environment that the sun directly shines and use down, and installation and use be defective easily inadequately.

The purpose of this utility model provides a kind of apparatus for heating water by solar energy, and it uses solar cell for supplying power to make low pressure PTC thermoelectric heating device generate heat to the heating in the water container and has electric power storage and AC power supply device.Make the round-the-clock use of its energy, use safer, convenience; To overcome the existing existing defective of solar water heater.

The purpose of this utility model is achieved in that solar panel is installed in the longest position at outdoor sunshine, and be connected with low pressure PTC thermoelectric heating device and storage battery with lead, the water in the low pressure PTC thermoelectric heating device heating power heating water container makes water be warmed up to the temperature and the insulation of suitable use; When water does not need to heat, the defeated next electric energy of battery stores solar panel.In no sunlight, give low pressure PTC thermoelectric heating device heating hot water by storage battery power supply, when the electricity deficiency of storage battery, by ac power supply hot water and to charge in batteries.

The utility model is characterized in that connecting the output of solar panel and the input of power supply automatic controller, the output of power supply automatic controller and water receiving temperature sensor and storage battery and low pressure PTC thermoelectric heating device with lead; Low pressure PTC thermoelectric heating device and heat-conducting insulation material are combined closely back and thermal conductor is combined closely combines closely with the water container that is right after inlet valve and flowing water Valve again; The input termination AC power of AC/DC changeover switch, output also connects PTC thermoelectric heating device and storage battery, control termination power supply automatic controller.

One of advantage that relatively the utlity model has with the solar water heater of existing similar techniques is that solar energy transducing head part can be installed separately with the hot water apparatus part, and does not influence the hot water effect.

Two of the advantage that the utlity model has is installations, easy to use.

Three of the advantage that the utlity model has is round-the-clockly to use.

Accompanying drawing is a structure chart of the present utility model.

In the drawings, [1] solar panel, [2] water container, [3] low pressure PTC thermoelectric heating device, [4] thermal conductor, [5] water temperature regulater, [6] flowing water Valve, [7] inlet valve, [8] heat-conducting insulation material, [9] power supply automatic controller, [10] storage battery, [11] AC/DC changeover switch, [12] direct current lead, [13] alternating current lead, [14] Alternating Current Power Supply control line.

Referring to accompanying drawing.

The utility model is by solar panel [1], water container [2], low pressure PTC thermoelectric heating device [3], thermal conductor [4], water temperature regulater [5], flowing water Valve [6], inlet valve [7], heat-conducting insulation material [8], power supply automatic controller [9], storage battery [10], AC/DC changeover switch [11], direct current lead [12], alternating current lead [13], Alternating Current Power Supply control line [14] is formed.
