Description of Embodiments
The embodiments of the present invention are described below in further detail in conjunction with drawings; however, the present invention may be implemented by many different ways limited and covered by clams appended herein.
As shown in FIG. 1 to FIG. 4, a solar energy powered semiconductor refrigeration fruit-vegetable freshness preservation box provided by the present invention comprises a box body composed of a lower base plate 3, an upper solar cell panel 12, a left solar cell panel 1, a right solar cell panel 13, a front solar cell panel 10 and a rear solar cell panel 9, wherein a mounting groove 5 is arranged inside the box body, an accumulator and a solar photovoltaic generation controller that are in connection with the upper solar cell panel 12, the left solar cell panel 1, the right solar cell panel 13, the front solar cell panel 10 and the rear solar cell panel 9 are mounted in the mounting groove 5, a plurality of lateral semiconductor chilling plates 2 in connection with the accumulator is mounted on the inner sides of the left solar cell panel 1, the right solar cell panel 13, the front solar cell panel 10 and the rear solar cell panel 9, and a plurality of upper semiconductor chilling plates 7 in connection with the accumulator is mounted on the inner side of the upper solar cell panel 12. An elastic buffer layer and a heat insulating layer are arranged inside the box body. The box body has a size of 40cm*30cm*30cm. The upper solar cell panel 12 is equivalent to a box cover.
Solar photovoltaic power generation technology is a clean power generation technology that converts solar energy into electrical energy; when applied to refrigeration fruit-vegetable freshness preservation boxes, the solar photovoltaic power generation technology is environment friendly and energy saving.
Since semiconductor refrigeration technology needs no refrigerant, causes no vibration or noises during working, has long service life and small inertia and so on, the semiconductor refrigeration technology is gradually applied to refrigeration engineering practices. Semiconductor refrigeration needs no mechanical mechanism and produces cold while being powered; therefore, the refrigeration speed is far quicker than that of conventional methods; moreover, the semiconductor refrigeration technology has a small size and is suitable to small space refrigeration.
Luminous energy is converted into electrical energy for the lateral semiconductor chilling plates 2 and the upper semiconductor chilling plates 7 to produce cold so as to achieve the effect of refrigeration; this process needs no mechanical part, has high running reliability, high energy utilization and is clean and free of pollution.
One ends of the lateral semiconductor chilling plates 2 and the upper semiconductor chilling plates 7 absorb heat while the other ends release heat. The refrigeration end (heat absorption end) is towards the inner side of the box body, providing cold for the inner side of the freshness preservation box, while the heat releasing end is towards the outside of the box body, releasing heat to the surrounding environment. Meanwhile, the fan 11 can evenly diffuse the cold to the inside of the box body, to accelerate refrigeration. A plurality of drain holes 4 is opened on the lower base plate 3, ensuring that the water flowing out during the fruit-vegetable freshness preservation process is drained out. A plurality of USB interfaces 6 in connection with the accumulator is mounted on the outer side wall of the left solar cell panel 1, the right solar cell panel 13, the front solar cell panel 10 or the rear solar cell panel 9. A handle 8 is connected on the outside of the upper solar cell panel 12, so that the box can be carried outside conveniently; the box body is divided into an upper layer and a lower layer by a bracket for classified freshness preservation; since the lower layer has a lower temperature and the upper layer has a higher temperature, the lower layer is designed as a freshness preservation area for animal meats, and the upper layer is designed as a freshness preservation area for fruits and vegetables. A fan 11 in connection with the accumulator is mounted on the inner side of the upper solar cell panel 12.
The lateral semiconductor chilling plates 2 and the upper semiconductor chilling plates 7 both are mounted adopting a dot matrix distribution.
The mounting groove 5 is arranged on the inner bottom of the box body.
The hole diameter of the drain hole 4 is less than 1 cm.
The plurality of USB interfaces 6 comprises a power input interface and a power output interface. In the case of no external power source, the solar energy powered semiconductor refrigeration fruit-vegetable freshness preservation box may be used to charge mobile devices such as mobile phone and tablet computer; in the case of no sunlight, the solar energy powered semiconductor refrigeration fruit-vegetable freshness preservation box may be powered by a vehicle power supply, to ensure the normal running of the fruit-vegetable freshness preservation box.
The current of the power output interface is designed as 1A or 2A by mounting a rectification circuit board. The power input interface is 5V.
The above are merely the preferred embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent structures or equivalent flow modifications made according to the description and the accompanying drawings of the present invention, or applied in other relevant technical fields directly or indirectly are intended to be included in the patent protection scope of the present invention.
