Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of ovens, in particular to a gas-saving electronic gas oven. BACKGROUND

[0002] With the rapid development of society and the improvement of people's living standards, barbecue has become a popular outdoor activity. Due to the emergence of various fire methods, the way of barbecue has gradually become diversified, and various types of barbecue ovens have been developed, which are generally divided into three categories: charcoal barbecue oven, gas barbecue oven and electric heating barbecue oven.

[0003] The existing gas oven can be divided into two types of barbecue cooking forms. One is that the combustion heating part is arranged directly below the grill net, and the heat released by the combustion heating part is transmitted upward to the food on the grill net, so that the food can be barbecued and cooked. The juice or cooking sauce produced during the barbecue and cooking of the food is easy to fall into the combustion heating part, which affects the combustion heating and easily produces oil fume, and on the other hand, it pollutes the combustion heating part and increases the cleaning work, which is not convenient to use. The other is that the combustion heating part is arranged directly above the grill net, and the heat released by the combustion heating part is transmitted downward to the food on the grill net, so that the food can be barbecued and cooked. Since the combustion heating part needs to be arranged directly above the grill net, it generally needs to be arranged with a connecting frame, and a certain distance needs to be kept between the combustion heating part and the grill net for placing the food during grilling, so that the overall volume of the oven is large and not convenient to carry. In addition, after the heat is released to the air, the hot air has an upward trend, and the heat cannot be well transmitted to the food below, affecting the barbecue and cooking effect of the food.

[0004] Or use a gas oven that uses fireless heat radiation to heat food. This type of oven has a higher heat utilization rate than the first two types, and the flame does not directly contact the food, so it is healthier to barbecue food. However, since it uses gas ignition heating, it is not accurate when controlling low temperature, and when the gas flame is infinitely small, it is easy to cause out-of-gas and out-of-fire state, which poses a certain risk. If small fire low temperature is used to roast food, a relatively thick temperature blocking material needs to be set, which causes waste of heat.

[0056] The temperature recovery module 4 comprises an outer furnace cover 401, an inner furnace cover 402, a temperature recovery pipe 403 and a smoke exhaust pipe 404. The outer furnace cover 401 is fixed in the oven shell 1, the inner furnace cover 402 is located in the outer furnace cover 401, and the space between the two is sealed and fixed by a sealing plate B 405.

[0058] The temperature recovery pipe 403 is provided with two C-shaped structures, and the temperature recovery pipe 403 is located between the outer furnace cover 401 and the inner furnace cover 402.

[0059] The back temperature pipe 403 is made of copper and is bent, two of which are symmetrically arranged in a C-shaped structure, which can make the air circulation more smooth, and the angle of the back temperature pipe 403 can make the gas circulate into the inner furnace chamber 302 when circulating the gas above, so that the food can be heated by the temperature without dead angle, and the temperature is more balanced, and because the smoke generated by combustion passes outside the back temperature pipe 403, the gas extracted from the bottom of the inner furnace cover 402 is heated again after passing through the back temperature pipe 403, and the heat is further utilized, and after the heat is completely utilized, the whole oven presents a stable and constant temperature state, which can be used for cooking food at high or low temperature.

[0061] The radiation plate 310 is used to block the radiation of the hollow copper pipe 303 above, and the radiation plate 310 is arranged to absorb the heat of the hollow copper pipe 303 and then act on the upper part of the inner furnace chamber 302, which can also achieve the effect of heat preservation and avoid the large difference in local temperature above the inner furnace chamber 302, which can cause the food to fail to be cooked.

[0062] The bottom surface of the inner furnace chamber 302 is fixedly provided with a heat preservation chamber 312, the heat preservation chamber 312 is a hollow structure, the heat preservation chamber 312 is above the hollow copper pipe 303, and the top wall of the inner furnace chamber 302 is embedded with parallel distributed heat conducting pipes 313.

[0066] In use, the ignition assembly 307 ignites the hollow copper pipe 303, the air hole 306 at the bottom of the placement groove 305 is used for combustion air, the heat of the hollow copper pipe 303 is transferred to both ends, after heating for a period of time, the temperature between the inner furnace chamber 302 and the outer furnace chamber 301 is increased, the food materials in the inner furnace chamber 302 can be heated, the bottom is the combustion place of the gas, the temperature is higher, the heat preservation chamber 312 can isolate the flame from the inner furnace chamber 302 to avoid the bottom of the food being quickly burned, the inside of the heat preservation chamber 312 is slowly heated for smooth heating of the food materials, the top loses heat quickly due to the flow of flue gas, the radiation plate 310 can converge heat, and the heat pipe 313 is in the top wall of the inner furnace chamber 302, so the heat at the top of the inner furnace chamber 302 can be transmitted downward through the heat pipe 313, ensuring that the temperature in the inner furnace chamber 302 is balanced, and as the exhaust process proceeds, heat is dissipated to the outside, the turbofan 408 operates, and the turbofan 408 can extract gas from the bottom of the inner furnace chamber 302 when the turbofan 408 operates, and then blows it to the upper part of the inner furnace chamber 302 through the back-temperature pipe 403. The circulation of air in the inner furnace chamber 302 using the back-temperature pipe 403 can achieve the effect of heat convection, not only improving the food processing efficiency, but also retaining heat in the inner furnace chamber 302, and during the exhaust process, the exhaust gas passes through the back-temperature pipe 403, so the back-temperature pipe 403 can be further heated, and the temperature of the circulating gas gradually increases. The food materials can also be roasted by hot air during roasting;

[0067] When preheating the inner furnace chamber 302, the electric heating pipe 3082 can release heat, and as the heat-reflecting half-circular cover 3081 operates, the electric heating pipe 3082 can preheat the inner furnace chamber 302, or the heat-reflecting half-circular cover 3081 operates to preheat the combustion space between the inner furnace chamber 302 and the outer furnace chamber 301. After preheating, the later gas ignition will be more smooth, and during high-temperature roasting, the flame of the ignition assembly 307 is increased, and the heat-reflecting half-circular cover 3081 is rotated to open the gap of the heat-transmitting groove body 3084. At this time, the heat of combustion will act on the inner furnace chamber 302. When processing food materials at the lowest temperature, turn off the ignition assembly 307 and use the electric heating pipe 3082 alone for heating. With the rotation of the electric heating pipe 3082, the heat of the electric heating pipe 3082 can be directly used, and the food materials can also be indirectly irradiated, achieving processing of food materials from low temperature to high temperature.
