Solar cooking device

Abstract

The invention discloses a solar cooking device, and aims to provide a solar cooking device which has the advantages of energy conservation, high efficiency, simple structure and easy implementation. The solar cooking device comprises a shell (1) and a cover body (2), wherein the cover body (2) is movably connected with the shell (1), a heat preservation cover plate (4) is arranged between the shell (1) and the cover body (2), a plurality of heat absorption mess tins (5) are arranged in the shell (1), and the inner surface of the shell (1) and the outer surfaces of the heat absorption mess tins (5) are coated with a heat absorption coating. The solar cooking device can be widely applied to the fields of cooking foods for family, camping and marching.

Description

technical field [0001] The invention relates to a cooker, in particular to a solar cooker. Background technique [0002] As we all know, in today's energy scarcity, if society wants to achieve great development, it must vigorously develop and utilize new energy sources. At present, social industrial production, technological development, and human life mainly rely on traditional resources such as oil, coal, and natural gas. The resources of the world are rapidly decreasing, and the future development of the whole society will face severe challenges. Relevant experts have foreseen the energy crisis in the future, calling on people to make rational use of traditional resources and vigorously develop new energy sources; solar energy is one of the most ideal new energy sources, and solar energy is generally Refers to the radiant energy of sunlight. The atomic nuclear reaction that fuses "hydrogen" into "helium" in the sun continuously releases huge energy. The energy that the su...

Problems solved by technology

Among them, the use of solar heat and light has gradually penetrated into people's daily life, such as solar water heaters, and recently there have been devices that use solar energy to cook food, thus breaking the tradition of using firewood, gas, natural gas, electrical appliances, etc. to cook food , effectively avoiding the high consumption of resources, and avoiding the pollution of the environment, so that the utilization of solar energy is closely integrated with the sustainable development of the world and environmental protection. However, due to the imperfection of technology, the existing solar cooking devices generally have complex structures, Defects such as high cost, low utilization rate of solar energy, and poor use effect

For example, the date of publication is January 17, 2007, and the publication number is a solar lunch box disclosed by CN 2857579Y. It only has a convex lens inside the lid, and utilizes the gathering effect of the convex lens to make the lunch box inside the lunch box through the irradiation of sunlight. For food heating, this structure not only has poor effect (it can only heat the food simply), but also only heats the food locally through the concentrating effect of the convex lens, which may cause the food irradiated by local strong light to burn, which is not conducive to the eater the health of people; as another example, the publication date is March 11, 2009, and the publication number is CN 101382346A disclosed a kind of household solar rice cooker, such as figure 1 As shown, it is composed of a solar heat collecting tube 1, a stainless steel outdoor fixed bracket 2, and a stainless steel indoor rice container 3. In the solar heat collecting tube 1, the other end is exposed in the indoor environment, and the solar heat collecting tube passes through the wall 5 at an angle of more than 45 degrees to complete the connection with the stainless steel outdoor fixing bracket 2 and the stainless steel indoor rice container 3, as can be seen from its structure , this domestic solar rice cooker is not easy to operate and implement, and all parts are fixed, so it cannot be used in a humanized way. user request

[0003] To sum up, the existing devices and utensils using solar energy for cooking have defects such as complex structure, low utilization rate of solar energy, poor use effect, etc.
