Design of control panel for multi-functional grill oven

With the continuous improvement of people's living standards, people's requirements for food quality are also getting higher and higher. Nowadays, summer is the season of barbecue, and it has become a trend of mass consumption whether going out for a picnic barbecue or eating barbecue in a store. However, the technical content of the existing barbecue boxes is very low, the energy consumption is high, and the pollution is very serious, and the existing outdoor barbecues all use charcoal fire for grilling. This traditional grilling method makes the food contain a lot of harmful substances. Seriously endanger people's health. However, my country's high-tech products in terms of barbecue boxes are very scarce, and its research and development market has broad prospects. Based on this, this paper proposes a design scheme of a multi-functional barbecue box, which uses solar power and temperature difference power generation, can realize automatic flipping of skewers, makes heating more uniform, and has oil fume absorption device and oil fume purification device. In addition, there is a temperature regulating device in the grill box, which can adjust the temperature and time of grilling according to different foods.

1. The overall design of the multi-function grill

The multi-functional barbecue box mainly includes solar power generation module, temperature sensor, temperature difference power generation module, oil fume absorption device, oil fume purification device, temperature adjustment device, single-chip microcomputer control module, automatic turning device and power supply module, and its design block diagram is shown in Figure 1. The multi-functional barbecue box takes the single-chip microcomputer control system as the core, and uses solar power generation and temperature difference power generation to provide electricity. The multi-functional grill box can also realize the automatic flipping of skewers to make the heating more uniform; at the same time, there are oil fume absorption devices and oil fume purification devices, as well as temperature adjustment devices, which can adjust the temperature and time of grilling according to different foods.

This design product adopts solar power generation and temperature difference power generation, utilizes new energy sources, saves energy and protects the environment, and conforms to the theme of the development of the current era. Moreover, it can intelligently control the temperature change, making it more convenient and quick for people to operate.

2. Application measures of multi-functional barbecue box

Put the grill under the sun, use solar power to provide electricity for the grill, turn on the switch, when the grill is working, the temperature inside the oven wall rises, and the thermoelectric power generation sheet generates a part of the electricity through the temperature difference inside and outside the oven and stores it in the battery. At the same time, start the oil fume absorption device, send the oil fume into the oil fume purification device to process this part of the polluted gas, and discharge the non-polluting gas into the air through the pipeline after double purification. When the switch is turned on, the automatic flipping device is started at the same time, so that the food is heated more evenly and the grilling effect is better. When the temperature sensor senses that the temperature is too high, the temperature regulating device is activated to automatically control the temperature in the oven to prevent food from being burnt or dangerous situations.

3. Innovative points in the development and design of barbecue boxes

(1) Solar power generation and thermoelectric power generation module: The multi-functional grill uses solar power generation and thermoelectric power generation to work together, and stores the electric energy in the battery to meet the power demand of the equipment itself. The solar panel is placed on the top of the grill, and the grill is placed under sunlight during the day, and the solar panel converts solar energy into electrical energy through photoelectric reaction, thereby realizing the power generation of the solar panel. The thermoelectric power generation piece is embedded in the inner wall of the oven, the heating surface of the power generation piece is attached to the high temperature inner wall, and the other side of the power generation piece is in the atmospheric environment of normal temperature, and the purpose of thermoelectric power generation is achieved through the large temperature difference between the two sides.

(2) Absorption and purification of oil fume: The oil fume absorption device of the multi-functional grill is located directly above the oven, which can absorb the oil fume to the first layer of purification device, and remove parts through mechanical collision between oil mist droplets and oil mist particles Dirt with larger particles. When the gas treated by the first-layer purification device enters the high-voltage electrostatic field, this part of the gas is ionized by the electrostatic field, so that most of the gas can be degraded and carbonized; Under the action, they are brought together and discharged from the pipeline. The gas treated by the first layer of oil fume purification device is inevitably polluting. The second layer of oil fume purifier uses the principle of activated carbon adsorption to remove most of the pollutants in the remaining gas.

(3) Temperature adjustment device: The temperature adjustment device uses a temperature sensor to automatically detect the internal temperature, and then transmits the signal to the single-chip microcomputer. The single-chip microcomputer processes the input signal and controls the fan placed inside the oven according to the temperature change. Adjust its speed to control the temperature within a certain range.

epilogue

The multi-functional barbecue box adopts solar power generation, utilizes new energy sources, saves energy and protects the environment, and conforms to the theme of the development of the current era. The grill also adopts double purification measures, which can efficiently collect lampblack, filter smoke and dust, and avoid direct discharge into the atmosphere to cause environmental pollution. And it can adjust the temperature intelligently, making it more convenient and quick for people to operate. Because the temperature of the inner wall of the barbecue box is very high, in order to effectively use this feature, a thermoelectric power generation sheet is installed, combined with solar power generation to meet its own electricity demand.
