Abstract-A practical and widely used heating gadget
heating can be prepared with a solar cooker. Because the user has go outside the kitchen to operate the typical solar cooker, it is not very user-friendly. Many professionals have modified the design of the solar cooker by employing a separate reflector in the outdoor field with focusing in the kitchen in order to overcome this drawback. Numerous professionals have additionally improved the inbox-type design for ease of use and more efficiency. Available solar cookers typically fall into two categories: box type and parabolic reflector focusing type.[9]
known as a solar cooker is out there. To increase the effectiveness of traditional sun cookers, these paper box type solar cookers incorporate copper tubes connected to water tanks. We evaluate the performance of a solar cooker with a copper tube and a water heater to the performance of a boxstyle solar cooker, and the difference is found to be significant. For cooking purposes, solar cookers offer renewable sources. Their biggest flaw is that they can't be used when there isn't enough sunlight.[6]The use of thermal energy storage (TEs) can significantly get around these restrictions. Solar energy is now used for a variety of purposes as a result of the reduction of fossil fuels and the rise in fuel prices. Flat reflectors are typically used in boxstyle solar cookers. The temperature within the solar cooker has been raised, and efforts have been made to improve the effectiveness of the water heater-heated box cooker. [11]However, the method of heat transfer into the storage medium affects the shape of the storage units. The power of the cookers was significantly influenced by the thermal diffusivity of the storage media and the design parameters of the cookers.
1.1 Box type Solar Cookers Features: A Box the Solar Cooker is essentially a glass-covered, insulated box with a top lid and a mirror on the inside that allows sunlight to enter the box when the lid is left open. The box's interior is painted in a dark color. The box containing the food to be prepared is lined with up to four pots that have been painted black. Rice, lentils, and vegetables are among the things the cooker can prepare in between one and two hours. Simple cakes, roasted cashew nuts, dry grapes, and other foods have all been prepared with the cooker. With the exception of the monsoon and overcast days, most of the year, it is a perfect appliance for household cooking. However, it cannot be used to make chapattis or for frying..

1.2 Advantages:
One of the many options for domestic and institutional cooking is solar cooking. Environmental pollution is decreased and conventional fuel (firewood and fossil fuels) are saved, both of which have ecological advantages. In order to permit cooking indoors and away from the sun, several of these efforts included adding thermal energy storage (TES) to solar cookers. The purpose of this study was to determine how TESu configurations and heat storage materials affected cooking performance. We are currently in a period when the global energy crisis is more widely recognized. Cooking is a routine activity all across the world. In order to make food safe, it is crucial to heat it to a high temperature that is sufficient to destroy microorganisms that can cause diseases. [5]According to the World Health Organization, diseases associated with indoor cooking cause around 4 million deaths annually. When placed in the sun, a cooker's interior temperature can rise from 100 degrees Celsius to 140 degrees Celsius in 2 to 3 hours. Therefore, only foods that require light

• There are no ongoing fuel costs when using solar cooking. Solar power is completely cost-free. • In a few years, the cost of the solar cooker can be readily recouped through fuel bill savings. • If used frequently, a box solar cooker can save three to four LPG cylinders per year. • Time is saved. While food cooks in the solar cooker, you are free to engage in other activities. • There is no concern about burning the meal. • Due to its slow cooking design, it ensures healthier and more nutrient-dense prepared food. • It is easy to use and long-lasting.
