Abstract
The invention provides a solar-energy electrothermal lunch box which comprises a solar energy plate, an external power source, a controller, a battery, an air valve, a temperature sensor and a thermal conductor; after the solar energy plate absorbs sunlight, luminous energy is converted into electric energy and inputted into the controller to charge the battery through the controller; the battery heats the thermal conductor through the controller; the temperature sensor is mounted on the thermal conductor, and feed the temperature of the thermal conductor back to the controller; when the temperature reaches a preset value, the controller controls the opening of the air valve, and water vapor is discharged.
Description
technical field:
The present invention relates to solar-electricity lunch box, belong to technical field of solar.
background technology:
Electric heating mess tin is as conventional tableware, by broad masses welcome, at present, most of electric heating mess tins are all that the parts such as electrothermal generator are installed in inside, and these electric heating mess tins can both carry out insulation effect, but it exists certain defect, because lunch box seals, in the time carrying out electrical heating, the circulation of lunch box steam inside is poor, heat time is long, electrothermal generator temperature is non-constant, and not power saving, when heating, lunch box internal temperature will soon decline, and can not get the effect of long-term heat preservation.
summary of the invention:
The present invention proposes solar-electricity lunch box, absorbs after sunshine by solar panels, and be electric energy principle by light energy conversion, through controller processing, give powered battery, battery heats to heat carrier by controller simultaneously, this invention can also be according to user's requirement, default any one temperature value.
For realizing above-mentioned object, the present invention adopts following technical scheme:
Solar-electricity lunch box, comprises solar panels, external power supply, and controller, battery, air valve, temperature sensor, heat carrier, as shown in Figure 1;
Solar panels absorb after sunshine, be that electric energy is input in controller by light energy conversion, charge the battery through controller, battery heats to heat carrier by controller simultaneously, temperature sensor is installed on heat carrier, the temperature Real-time Feedback of heat carrier is returned in controller, in the time that temperature reaches preset value, controller control air valve is opened, and discharges water vapour.
Described controller can be preset any one temperature value, makes the temperature of lunch box inside keep constant temperature.
This described system also has external power supply, charges the battery by controller, prevents powered battery deficiency.
Beneficial effect of the present invention:
This system is to be electric energy principle by light energy conversion, and solar panels are absorbed after sunshine through controller processing, gives powered battery, not only power saving but also energy-conserving and environment-protective, and temperature can arrange arbitrarily, makes lunch box internal temperature keep constant.
accompanying drawing explanation:
Fig. 1 system block diagram of the present invention.
the specific embodiment:
In order to make technical method of the present invention clearer, below in conjunction with Fig. 1 and embodiment, the present invention is described in more detail, and instantiation described herein only, in order to explain the present invention, is not limited to the present invention.
embodiment:
Solar panels absorb after sunshine, be that electric energy is input in controller by light energy conversion, charge the battery through controller, battery heats to heat carrier by controller simultaneously, temperature sensor is installed on heat carrier, the temperature Real-time Feedback of heat carrier is returned in controller, in the time that temperature reaches preset value, controller control air valve is opened, discharge water vapour, controller can be according to user's demand, set temperature value arbitrarily, make the temperature of lunch box inside keep constant temperature, this system also has external power supply, charge the battery by controller, prevent powered battery deficiency.
