Description

Technical Field

[0001] The invention relates to the technical field of ovens, in particular to a gas-saving type electronic gas oven. Background Art

[0002] With the rapid development of society and the improvement of people's living standards, barbecue has become an outdoor activity that is widely loved by the public. Due to the emergence of various ways of using fire, the way of barbecue has gradually become diversified, and various barbecue grills have been developed, which are generally divided into three categories: charcoal barbecue grills, gas barbecue grills and electric barbecue grills.

[0003] Existing gas grills can generally be divided into two types of barbecue cooking. One is that the combustion and heating part is arranged just below the grill, and the heat released by the combustion and heating part is transferred upward to the food on the grill, so that the food can be barbecued. In this structure of the grill, when the food is barbecued, the juice or cooking sauce produced by it is easy to fall to the combustion and heating part, which will affect the combustion and heating situation and easily generate oil smoke. On the other hand, it will pollute the combustion and heating part, increase the cleaning work, and be inconvenient to use; the other is that the combustion and heating part is arranged just above the grill, and the heat released by the combustion and heating part is transferred downward to the food on the grill, so that the food can be barbecued. In this structure of the grill, since the combustion and heating part needs to be arranged just above the grill, it generally needs to be provided with a connecting frame, and a certain distance needs to be spaced between the combustion and heating part and the grill for the food to be placed when grilling, so that the overall size of the oven is large and inconvenient to carry. In addition, after the heat is released into the air, the hot air has an upward trend, and the heat cannot be well transferred to the food below, affecting the barbecue cooking effect of the food.

[0004] Or a gas grill that uses fireless heat radiation to heat food. This type of grill has a higher heat utilization rate than the first two types, and the flame does not directly contact the food, so grilling ingredients is healthier. However, since it uses a heating method that ignites gas, it is not accurate enough when controlling low temperatures. When the gas flame is infinitely reduced, it is easy to cause flameout and air leakage, which leads to certain dangers. If food is baked at a low temperature over a low fire, a thicker temperature barrier material needs to be set, which in turn causes heat waste. This is a direct problem currently faced by gas grills, and there is no better way to overcome it in this field. Summary of the invention

When the opening surface of the heat reflecting semicircular cover faces the inner furnace bin, the heat reflecting semicircular cover closes the heat-transmitting grooves. When the opening surface of the heat reflecting semicircular cover faces outside the inner furnace bin, the heat-transmitting grooves are in a through state.

[0011] Preferably, an electrical insulation compartment is fixedly installed at the bottom of the inner furnace compartment corresponding to the position of the reduction motor, and the reduction motor is located inside the electrical insulation compartment.

[0012] Preferably, the reheating module includes an outer furnace hood, an inner furnace hood, a reheating pipe and a smoke exhaust pipe.

The interior of the inner furnace hood is connected with the inner furnace bin, and the smoke collecting duct is connected with the space between the inner furnace hood and the outer furnace hood.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. This energy-saving electronic gas grill is provided with a grilling module. When the flame of the ignition component acts on the hollow copper tube, the heat will gather between the inner furnace bin and the outer furnace bin, and the heat will flow into the smoke collecting duct along the space between the inner furnace bin and the outer furnace bin. At this time, the hollow copper tube will heat the inner furnace bin, and the heat will be concentrated on the hollow copper tube. The long-lasting heat storage further improves the heat utilization rate. When the temperature is low in the early stage, the heat reflecting semicircular cover can be rotated to make the electric heating tube heat the space between the inner furnace bin and the outer furnace bin, so as to achieve the effect of preheating in advance and facilitate ignition. When the fire is turned off at the bottom, the heat reflecting semicircular cover is flipped into the inner furnace bin, and the food can be baked at low temperature. The operation of the heat reflecting semicircular cover can change the amount of heat from the side wall entering the inner furnace bin, so as to achieve seamless conversion from low temperature to high temperature in multiple stages during the baking process. When it is actually used at a high frequency, the gas fuel consumption will be greatly reduced under the same heat environment.

[0019] 2. This energy-saving electronic gas oven has the problem of heat gathering upwards in gas ovens, and most of the heat is dissipated to the outside during the exhaust process, so the gas consumption of traditional gas ovens is very large. By setting up a temperature return module and using the temperature return pipe to circulate the air in the inner furnace chamber, the effect of heat convection can be achieved, which not only improves the food processing efficiency, but also retains the heat in the inner furnace chamber. Moreover, when exhausting smoke, the exhaust smoke will pass through the temperature return pipe, so the temperature return pipe can be further heated, thereby achieving the effect of energy-saving baking of ingredients.

[0020] 3. This energy-saving electronic gas oven is equipped with a heat preservation chamber, a radiation plate and a heat pipe. The bottom is where the gas burns, so the temperature is relatively high. The heat preservation chamber can isolate the flame from the inner furnace chamber to prevent the bottom of the food from being quickly burned. The heat preservation chamber can also heat the ingredients steadily. The heat loss at the top is fast, so the radiation plate can gather the heat. The heat pipe is in the top wall of the inner furnace chamber, so the heat at the top of the inner furnace chamber can be transferred downward through the heat pipe, ensuring the temperature balance in the inner furnace chamber, so that the food can be heated from multiple directions, achieving the effect of evenly using heat to cook the ingredients.

[0021] 4. This energy-saving electronic gas grill is equipped with a smoke exhaust pipe and a placement slot. The air holes can provide rapid air intake for combustion, and the exhaust pipe can be used to discharge the gas after combustion, avoiding direct contact between food and heat source, ensuring the cleanliness of the ingredients.

The door panel 2 is similar to the structure of the existing gas oven and can be made of transparent high-temperature resistant glass or metal plate. It is connected to the oven shell 1 in a hinged form, which can isolate heat when closed and can also be clamped and fixed to the oven shell 1. A temperature monitoring module is provided inside the oven shell 1 and a display screen is provided outside. The display screen can observe the gas ignition status and combustion status, and the display screen can also display real-time temperature and various switching data.

[0051] The outer furnace chamber 301 and the inner furnace chamber 302 are both made of metal stamping and are socketed together. The smoke collecting duct 304 is a raised structure on the top of the outer furnace chamber 301. The smoke collecting duct 304 and the outer furnace chamber 301 are stamped as an integrated structure. The smoke collecting duct 304 is located in the middle and above for easy exhaust. Each hollow copper tube 303 is a complete copper tube with closed ends and symmetrically bent. The flame of the ignition component 307 acts on multiple heat-conducting copper tubes at a time.

[0052] The electric-controlled auxiliary heating assembly 308 includes a heat-reflecting semicircular cover 3081, an electric heating pipe 3082 and a reduction motor 3083. The heat-reflecting semicircular cover 3081 is a semicircular tubular structure. The side wall of the inner furnace chamber 302 is provided with a plurality of heat-transmitting grooves 3084 connected inside and outside. The heat-reflecting semicircular cover 3081 is in the heat-transmitting grooves 3084. The upper and lower ends of the heat-reflecting semicircular cover 3081 are provided with main shafts. The heat-reflecting semicircular cover 3081 is rotatably connected to the inner furnace chamber 302. The reduction motor 3083 is provided with a heat-transmitting groove 3084. 3083 is fixed at the bottom of the inner furnace bin 302, the output shaft of the reduction motor 3083 is connected to the bottom main shaft of the heat reflecting semicircular cover 3081, the electric heating tube 3082 is fixed in the heat reflecting semicircular cover 3081, when the opening surface of the heat reflecting semicircular cover 3081 faces the inner furnace bin 302, the heat reflecting semicircular cover 3081 closes the heat-transmitting groove body 3084, when the opening surface of the heat reflecting semicircular cover 3081 faces the outside of the inner furnace bin 302, the heat-transmitting groove body 3084 is in a through state.

[0053] The electric heating tube 3082 is a glass heating tube, the outside of which is a high-temperature resistant quartz tube and is vacuumed, the internal heating wire is a resistance wire, and the heat reflecting semicircular cover 3081 is provided with a reflecting layer on the side close to the electric heating tube 3082, which can reflect a certain amount of heat from the electric heating tube 3082, and the outside of any reduction motor 3083 is wrapped with a high-temperature resistant fabric layer. The heat reflecting semicircular cover 3081 rotates at a low speed in the inner furnace chamber 302, and the maximum rotation angle each time is one hundred and eighty degrees. The rotation process is basically not affected by temperature, and the internal connecting cables are also wrapped with high-temperature resistant treatment.

[0054] An electrical insulation chamber 3085 is fixedly installed at the bottom of the inner furnace chamber 302 corresponding to the position of the reduction motor 3083 , and the reduction motor 3083 is located inside the electrical insulation chamber 3085 .

[0055] The electrical insulation chamber 3085 is coated both inside and outside to protect the reduction motor 3083 and the internal drive board and other circuit components.

[0056] The temperature recovery module 4 includes 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, and the inner furnace cover 402 is in the outer furnace cover 401. The space between the two is sealed and fixed by a sealing plate B405. The interior of the inner furnace cover 402 is connected to the inner furnace bin 302, and the smoke collecting duct 304 is connected to the space between the inner furnace cover 402 and the outer furnace cover 401. The smoke exhaust pipe 404 is fixed on the outer furnace cover 401 and connected to the outer furnace cover 401 and the inner furnace cover 402. 2 is connected, the other end of the smoke exhaust pipe 404 passes through the oven shell 1, a circulation chamber 406 is fixedly installed on the bottom surface of the inner furnace cover 402, the upper end of the temperature return pipe 403 is fixed to the upper end of the inner furnace cover 402, and the lower end is fixed to the circulation chamber 406 and connected to each other, and an air groove 407 connected to the circulation chamber 406 is provided on the inner bottom wall of the inner furnace cover 402 corresponding to the circulation chamber 406, and a turbofan 408 is installed at the end of the circulation chamber 406 corresponding to the temperature return pipe 403 for circulating the gas in the temperature return pipe 403.

[0057] The smoke exhaust pipe 404 is connected to the outdoors, and heat dissipation holes are provided on the outside of the smoke exhaust pipe 404. If the outside air flow rate is difficult to achieve a siphon effect, a siphon device can also be installed in the smoke exhaust pipe 404. A sealed space is formed between the inner furnace cover 402 and the outer furnace cover 401, and the burning smoke will exist in the sealed space and then be discharged along the smoke exhaust pipe 404. The burning smoke will not enter the inner furnace bin 302 and will not affect the food. The inner bottom wall height of the inner furnace cover 402 is slightly higher than the inner bottom wall height of the inner furnace bin 302. If grease appears in the inner furnace bin 302 due to cooking food, the grease will not flow into the circulation bin 406. The volute fans arranged in the circulation bin 406 all use metal blades and the power supply is treated to be resistant to high temperatures.

[0058] Two temperature return pipes 403 are provided. The temperature return pipes 403 are of a C-shaped structure and are located between the outer furnace cover 401 and the inner furnace cover 402 .

[0059] The temperature return pipe 403 is made of bent copper material, and the two are symmetrically arranged. The C-shaped structure can make the air circulation smoother, and the angle of the temperature return pipe 403 can allow the gas to circulate into the inner furnace chamber 302 when the gas circulates above. Therefore, when heating the food, the food can be heated with a temperature without dead ends, and the temperature is relatively balanced. Moreover, since the combustion smoke passes outside the temperature return pipe 403, the gas extracted from the bottom of the inner furnace cover 402 will be heated again after passing through the temperature return pipe 403, and the heat will be further utilized. After the heat is fully utilized, the entire oven presents a stable state with constant temperature all around. For cooking food, both high-temperature baking and low-temperature baking can be done with ease.

[0060] A radiation plate 310 is provided below the hollow copper tube 303 on the inner furnace chamber 302. The radiation plate 310 is provided with through holes 311 distributed in a matrix. Both ends of the radiation plate 310 are fixed to the front and rear sealing plates A309.

[0061] The radiation plate 310 is used to block the radiation from the hollow copper tube 303 above. The radiation plate 310 can absorb the heat of the hollow copper tube 303 and then smoothly act on the upper part of the inner furnace chamber 302, thereby achieving the effect of heat preservation and avoiding large local temperature changes above the inner furnace chamber 302, which may lead to failure in cooking of ingredients.

[0062] A heat preservation chamber 312 is fixedly installed on the bottom surface of the inner furnace chamber 302 . The heat preservation chamber 312 is a hollow structure. The heat preservation chamber 312 is located above the hollow copper tube 303 . The top wall of the inner furnace chamber 302 is embedded with parallelly distributed heat conduction pipes 313 .

[0063] The heat preservation chamber 312 arranged at the bottom has a similar effect to the radiation plate 310 above, but the heat preservation chamber 312 can directly isolate the burning of the flame. After the internal temperature rises, it acts on the bottom of the inner furnace chamber 302. Therefore, when cooking food at the beginning, there is no need to preheat the furnace body first, or turn off the fire after preheating, and cooking can be carried out directly, and the open flame at the bottom will not burn the food.

[0064] The ignition assembly 307 includes a main gas pipe 3071 and multiple auxiliary gas pipes 3072 . The multiple auxiliary gas pipes 3072 are connected to the main gas pipe 3071 . The main gas pipe 3071 and the auxiliary gas pipes 3072 are both located in the placement groove 305 and under the hollow copper tube 303 .

[0065] The main gas pipe 3071 is connected to the external natural gas pipeline, and is provided with valves and pressure detection components inside. The auxiliary gas pipe 3072 is provided with a plurality of gas nozzles, and is also equipped with an electronic igniter and a temperature detection component.

[0066] When in use, the ignition component 307 ignites and burns the hollow copper tube 303, and the air hole 306 at the bottom of the placement groove 305 is used for combustion intake. The heat of the hollow copper tube 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 increases, and the food in the inner furnace chamber 302 can be heated. The bottom is where the gas burns and the temperature is relatively high. The heat preservation chamber 312 can isolate the flame from the inner furnace chamber 302 to prevent the bottom of the food from being quickly burned. The inside of the heat preservation chamber 312 is slowly heated to heat the food steadily. The heat loss at the top is fast due to the flow of smoke, and the radiation plate 310 can gather heat. Moreover, 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 The heat is transferred downward through the heat conducting pipe 313 to ensure the temperature balance in the inner furnace bin 302. During the smoke exhaust process, the heat is dissipated to the outside, and the turbofan 408 is running. When the turbofan 408 is running, the gas at the bottom of the inner furnace bin 302 can be extracted from the gas slot 407, and then blown to the top of the inner furnace bin 302 through the temperature return pipe 403. The temperature return pipe 403 is used to circulate the air in the inner furnace bin 302 to achieve the effect of heat convection, which not only improves the food processing efficiency, but also retains the heat in the inner furnace bin 302. Moreover, when exhausting smoke, the exhaust smoke will pass through the temperature return pipe 403, so the temperature return pipe 403 can be further heated, so that the temperature of the circulating gas will gradually increase, and the food can be roasted by hot air when baking;

[0067] When preheating the inner furnace bin 302, the electric heating pipe 3082 can release heat. With the operation of the heat reflecting semicircular cover 3081, the electric heating pipe 3082 can preheat the inner furnace bin 302, or the heat reflecting semicircular cover 3081 can be operated to the other side to preheat the combustion space between the inner furnace bin 302 and the outer furnace bin 301. After preheating, the later gas ignition will be smoother. When roasting at high temperature, the flame of the ignition component 307 is increased, and the heat reflecting semicircular 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 bin 302. When processing food at the lowest temperature, turn off the ignition component 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 utilized, and the food can be processed from low temperature to high temperature without directly irradiating the food.
