Description

Technical Field

[0001] The utility model relates to the field of ovens, in particular to an oil fume separation electric oven. Background Technique

[0002] With the improvement of people's living standards, people's eating habits have also changed accordingly. People will not only bring barbecue equipment to the wild for barbecue, but also often gather some friends at home for barbecue. The practice of barbecue has become more and more common, and the barbecue equipment has developed by leaps and bounds.

[0003] Referring to the utility model patent with the publication number CN217090424U and the name of an electric oven with an oil filter net, which includes a bottom case. An installation cavity is arranged in the bottom case. An insulation plate, a heating component and a baking tray are arranged in the installation cavity from bottom to top in sequence. The insulation plate is provided with a receiving cavity. The baking tray and the heating component are both arranged in the receiving cavity. An air inlet and an air outlet are respectively arranged on the side walls on both sides of the receiving cavity and are located above the baking tray after assembly. A filter net and a fan are also arranged in the installation cavity. The filter net is arranged on one side of the air inlet. One end of the filter net is closely attached to the side wall of the installation cavity on the side of the air inlet. The other end of the filter net is aligned with the air inlet so that the oil fume entering from the air inlet is blown towards the filter net. When in use, the fan works and generates suction so that the oil fume above the baking tray enters the installation cavity from the air inlet and passes through the filter net and then is blown out from the air outlet. This kind of oven has the following two disadvantages: 1. After the oil fume enters the air inlet, it directly contacts the fan, and the oil stain will pollute the fan, resulting in noise in the operation of the fan, increased energy consumption, and the fan is difficult to clean and is not hygienic enough; 2. The air inlet is located above the baking tray and is arranged in a single row, and it is difficult to adsorb the oil fume generated at a relatively far distance from the air inlet on the baking tray, and the suction effect on the oil fume is limited. Content of the Utility Model

[0004] In order to solve the above problems, the utility model provides an oil fume separation electric oven, which solves the problems that the fan is polluted by oil fume and the effect of sucking oil fume is not good.

[0005] The technical solution adopted by the present utility model is as follows: An oil fume separation electric grill, comprising a housing, a heat insulation plate, a heating component, and a baking tray. The housing is arranged with its opening facing upwards. The heat insulation plate, the heating component, and the baking tray are sequentially connected to the housing from bottom to top. An electrical interface is provided on the housing. An exhaust duct assembly is further provided inside the housing. The exhaust duct assembly includes an air inlet port and an air outlet port. A fan is installed at the air inlet port. The fan and the heating component are electrically connected to the electrical interface. The exhaust duct assembly includes suction pipes. The number of suction pipes is two and they are respectively arranged on opposite sides of the housing. A plurality of flow guiding plates are provided on the suction pipes. The flow guiding plates protrude towards the baking tray side. The extending direction of the flow guiding plates faces the air inlet port side. An air suction port is formed between the edge of the flow guiding plate and the suction pipe. A filtering device is provided between the suction pipe and the air outlet port.

[0006] Through the above technical solution, the fan is installed at the air inlet port. When the gas in the suction pipe flows rapidly, a negative pressure is generated. The oil fume enters the suction pipe through the air suction port and finally flows out at the air outlet port. The fan does not come into direct contact with the oil fume during operation, so the oil fume will not pollute the fan, avoiding the situations of noise and increased energy consumption, and also making the use more hygienic. The number of suction pipes is two and they are arranged oppositely, making the oil fume suction effect stronger.

[0007] Further, in the direction of the gas flow in the suction pipe, the cross-sectional area of the suction pipe gradually decreases.

[0008] Through the above technical solution, in the direction of the gas flow in the suction pipe, the gas flow velocity gradually becomes faster, compensating for the energy loss generated during the gas flow in the suction pipe and ensuring the efficiency of oil fume suction.

[0009] Further, the arc surface between the flow guiding plate and the side wall of the suction pipe has a smooth transition.

[0010] Through the above technical solution, the gas flows more smoothly in the suction pipe, reducing the situation of local air vortices formed at the flow guiding plate, and making the oil fume suction effect more stable.

[0011] Further, the exhaust duct assembly includes inflow pipes. The inflow pipes are located between the air inlet port and the suction pipes. The number of inflow pipes is two. A flow dividing plate is provided between the two inflow pipes. The end of the flow dividing plate is aligned with the central part of the fan.

[0012] Through the above technical solution, the air brought in by the fan is evenly distributed to the two inflow pipes, making the oil fume suction effects generated on the two suction pipes more uniform.

[0013] Furthermore, the filtering device includes a mounting shell and oil-absorbing sheets. The number of the oil-absorbing sheets is at least two, and each of the oil-absorbing sheets is staggeredly mounted in the mounting shell. The mounting shell and the air outlet port are detachably arranged.

[0014] Through the above technical solution, the oil-absorbing sheets are staggeredly arranged, so that the gas mixed with oil fume flows through a curved path at the filtering device, enabling the oil-absorbing sheets to fully adsorb the oil fume in the gas. After the mounting shell is detached from the air outlet port, it can be cleaned and replaced in time.

[0015] Furthermore, a positioning protrusion is provided on the mounting shell, a connecting gap is formed on the edge of the air outlet port, a clamping gap is communicated at the end of the connecting gap, the connecting gap and the clamping gap are bent with each other, and the positioning protrusion is clamped into the clamping gap through the connecting gap.

[0016] Through the above technical solution, the structures of the positioning protrusion, the connecting gap and the clamping gap are simple and convenient to use. Description of the Drawings

[0030] Refer to Figures 1-4, An oil fume separation electric grill, comprising a housing 1, a heat insulation plate 2, a heating component 3, and a baking tray 4. The housing 1 is arranged with its opening facing upwards. The heat insulation plate 2, the heating component 3, and the baking tray 4 are sequentially connected to the housing 1 from bottom to top. An electrical interface 101 is provided on the housing 1. An exhaust duct assembly 5 is further provided inside the housing 1. The exhaust duct assembly 5 includes an air inlet port 501 and an air outlet port 502. A fan 6 is installed at the air inlet port 501. The fan 6 and the heating component 3 are electrically connected to the electrical interface 101. The exhaust duct assembly 5 includes suction pipes 503. The number of suction pipes 503 is two and they are respectively arranged on opposite sides of the housing 1. A number of flow guide plates 504 are provided on the suction pipes 503. The flow guide plates 504 protrude towards the baking tray 4 side. The extending direction of the flow guide plates 504 faces towards the air inlet port 501 side. An air suction port 505 is formed between the edge of the flow guide plate 504 and the suction pipe 503. A filtering device 7 is provided between the suction pipe 503 and the air outlet port 502.

[0031] The fan 6 is installed at the air inlet port 501. When the gas in the suction pipe 503 flows rapidly, a negative pressure is generated. The oil fume enters the suction pipe 503 through the air suction port 505 and finally flows out at the air outlet port 502. The fan 6 is not in direct contact with the oil fume during operation, so the oil fume will not contaminate the fan 6, avoiding the situations of noise and increased energy consumption, and also making it more hygienic to use; the number of suction pipes 503 is two and they are arranged oppositely, making the oil fume suction effect stronger.

[0032] In the direction of gas flow in the suction pipe 503, the cross-sectional area of the suction pipe 503 gradually decreases.

[0033] In the direction of gas flow in the suction pipe 503, the gas flow velocity gradually becomes faster, compensating for the energy loss generated during the gas flow in the suction pipe 503 to ensure the efficiency of sucking oil fume.

[0034] In the present utility model, the gas flows in from the air inlet port 501 and discharges from the air outlet port 502. The direction of gas flow in the suction pipe 503 is from the end close to the air inlet port 501 to the end close to the air outlet port 502.

[0035] The heating component 3 referred to herein is a commonly used curved heating tube on the market and will not be elaborated here.

[0036] The arc between the flow guide plate 504 and the side wall of the suction pipe 503 has a smooth transition.

[0037] This makes the gas flow more smoothly in the suction pipe 503, reducing the situation of local air vortices formed at the flow guide plate 504, and making the oil fume suction effect more stable.

[0038] Reference Figures 2-4, the exhaust duct assembly 5 includes an inlet pipe 506 located between the intake port 501 and the suction pipe 503. The number of inlet pipes 506 is two. A flow splitter plate 507 is arranged between the two inlet pipes 506, and the end of the flow splitter plate 507 is aligned with the central part of the fan 6.

[0039] This causes the air brought in by the fan 6 to be evenly divided into the two inlet pipes 506, making the oil fume suction effect on the two suction pipes 503 more uniform.

[0040] Reference Figure 2 , 5 , 6, the filtering device 7 includes a mounting shell 701 and oil-absorbing sheets 702. The number of oil-absorbing sheets 702 is at least two, and each oil-absorbing sheet 702 is staggeredly installed in the mounting shell 701. The mounting shell 701 and the air outlet port 502 are detachably arranged.

[0041] The oil-absorbing sheets 702 are staggeredly arranged, so that the gas mixed with oil fume flows through a curved path at the filtering device 7, enabling the oil-absorbing sheets 702 to fully adsorb the oil fume in the gas. After the mounting shell 701 is detached from the air outlet port 502, it can be cleaned and replaced in time.

[0042] Preferably, the number of oil-absorbing sheets 702 is four, and the oil-absorbing sheets 702 are plate-shaped formed by fiber polylactic acid polymerization.

[0043] The mounting shell 701 is provided with positioning protrusions 703. A connection gap 508 is formed on the edge of the air outlet port 502. A clamping gap 509 is communicated at the end of the connection gap 508. The connection gap 508 and the clamping gap 509 are bent with each other, and the positioning protrusions 703 are clamped into the clamping gap 509 through the connection gap 508.

[0044] The structures of the positioning protrusions 703, the connection gap 508 and the clamping gap 509 are simple and convenient to use.

[0045] Preferably, the number of positioning protrusions 703 is two and they are evenly distributed in the circumferential direction. The corresponding numbers of the connection gap 508 and the clamping gap 509 are also two, and both the connection gap 508 and the clamping gap 509 are evenly distributed in the circumferential direction.

[0046] When the utility model is in use, the baking tray 4 is heated, and the cooking oil on the baking tray 4 reaches the boiling point and generates oil fume; the fan 6 is powered on and sucks in the outside air from the intake port 501, and then it is split by the flow splitter plate 507 into the two inlet pipes 506; then it flows through the suction pipe 503. The gas in the suction pipe 503 flows rapidly to form a negative pressure, and the oil fume generated on the baking tray 4 enters the suction pipe 503 through the suction port 505; finally, the gas mixed with oil fume is filtered through the flow channels formed by the respective oil-absorbing sheets 702 and discharged from the air outlet port 502.

[0047] The above are only the preferred embodiments of the present utility model, and thus do not limit the patent scope of the present utility model. Any equivalent structural transformation made under the inventive concept of the present utility model by using the content of the specification and drawings of the present utility model, or any direct / indirect application in other related technical fields shall be included within the patent protection scope of the present utility model.
