Description

Technical Field

[0001] The utility model relates to the technical field of ovens, and more particularly to a multifunctional oven. Background Art

[0002] Ovens are used to bake food and are widely used in the catering industry and various households. Traditional ovens mostly use wood or charcoal as fuel for combustion and heating. Compared with ovens heated by electricity or natural gas, traditional ovens use charcoal to bake food with a stronger aroma, so traditional ovens have always been popular. However, existing traditional ovens have problems such as insufficient utilization of fuel waste heat, low heating efficiency, and oil fume emissions that pollute the environment, and cannot well meet user needs.

[0003] In the prior art, an outdoor barbecue grill with a thermoelectric power generation function includes a grill body, multiple legs, two support bases, a motor, a power module, a rotating rod, and a thermoelectric power generation module. The legs are fixedly connected to the grill body to support the grill body. The two support bases are fixed to the top of the grill body. A plurality of barbecue forks are fixed to the rotating rod, which is rotatably mounted on the two support bases. The motor is fixed to the outer side of one of the support bases and connected to the rotating rod. The hot end of the thermoelectric power generation module is fixed to the outer side of the grill body, and a heat dissipation assembly is provided at the cold end of the thermoelectric power generation module. The thermoelectric power generation module, power module, and motor are sequentially electrically connected. This device, by arranging the thermoelectric power generation module on the outer side of the grill body, absorbs heat from the grill body to generate electricity, which is then transmitted to the motor via the power module, eliminating the need for an additional power supply. However, the heat dissipation assembly of the barbecue grill passively dissipates heat through a heat conducting plate, resulting in insufficient heat dissipation, which in turn affects the power generation efficiency of the thermoelectric power generation module. The heat generated by the heat source within the grill is not efficiently utilized, as only a portion of the heat is absorbed and converted into electricity, while a significant amount of heat is still dissipated, resulting in inadequate utilization of the residual heat.

[0004] There is also a movable oven with oil fume purification, comprising an outer shell body, an air duct fixedly mounted inside the upper end of the outer shell body, an air inlet mask fixedly mounted on the upper end of the air duct, a heating plate mounted on the upper end of the air inlet mask, a heat insulation plate provided between the air inlet mask and the heating plate, an electric control panel installed on one side of the upper surface of the air inlet mask, movable telescopic legs connected to the four corners of the lower end of the outer shell body, a mains socket installed on one outer side of the outer shell body, and a USB port installed on the side of the mains socket on the outer shell body. This movable oven with oil fume purification has the function of absorbing oil fume and purifying air, and can effectively absorb and purify oil fume and harmful gases generated when the oven is used. However, its oil fume removal method is to capture and block large particles of oil fume and grease with a filter, and cannot capture tiny oil fume particles, resulting in low purification efficiency and the need to regularly clean and replace the filter. Utility Model Content

[0005] The utility model aims to overcome the defect of low utilization rate of waste heat of the oven in the prior art and provide a multifunctional oven which fully utilizes the waste heat of the oven.

[0006] In order to solve the above technical problems, the technical solution adopted by the present invention is: a multifunctional oven, comprising: a furnace body, a combustion furnace, a barbecue grill, an air inlet duct and a smoke exhaust pipe, the combustion furnace is arranged in the hollow cavity of the furnace body, the air inlet duct is installed on the outside of the furnace body, and one end of the air inlet duct is connected to the combustion furnace, and the other end is connected to the outside of the furnace body, the smoke exhaust pipe is installed on the top of the furnace body, the barbecue grill is installed above the combustion furnace, and also includes a thermoelectric power generation component and a first exhaust fan installed in the air inlet duct, and a power storage module installed on the furnace body, the thermoelectric power generation component includes a thermoelectric power generation element and a heat sink, the hot end of the thermoelectric power generation element is connected to the top of the furnace body, and the cold end is connected to the heat sink, the output ends of the first exhaust fan and the thermoelectric power generation element are respectively electrically connected to the power storage module.

This improves the utilization rate of the waste heat of the furnace body and also improves the power generation voltage and power generation efficiency. At the same time, the temperature of the air rises when it flows through the heat sink, providing relatively high-temperature air for the furnace body, improving the combustion efficiency of the fuel in the furnace body, avoiding temperature fluctuations in the furnace body, and improving the baking effect. The thermoelectric power generation element can be a semiconductor power generation sheet or a thermocouple power generation element.

The metal rod is connected to the negative pole and the cylindrical metal part is connected to the positive pole. When the two are energized, an electric field will be formed, and corona discharge will be generated between the metal thorns and the inner wall of the cylindrical metal part.
