Description

Technical Field

[0001] The utility model relates to the technical field of oven fume treatment, and more specifically to a high-temperature fume filtering device and an oven thereof. Background Art

[0002] The oven is a widely used household food baking device. It uses the heat radiation generated by the heating element in the inner tank of the oven body after being powered on, so that the food in the inner tank is continuously baked and slowly cooked. The surface temperature of the food rises rapidly during the baking process, and oil smoke is generated due to thermal oxidation of fat in a high temperature environment. Therefore, electric ovens and ovens on the domestic and foreign markets will generate oil smoke when cooking food, and the higher the oven temperature, the greater the oil smoke.

[0003] In order to avoid oil smoke from contaminating food, traditional ovens generally use an open-type grilling method, that is, baking food in an environment that is connected to the outside world, so that the oil smoke will continue to evaporate during baking. However, open-type baking will form a pungent oil smoke smell in the indoor environment, and the oil smoke will adhere to the walls or roof after evaporation, causing obvious adverse effects on the indoor and outdoor environment, polluting all items near the oven, and also affecting the health of the operator and participants.

[0004] In order to improve this drawback, most of these products limit the maximum oven temperature to 250°C. Some consumers place the products in places with range hoods for cooking, or simply move them to the balcony or outdoors for cooking. This affects the user experience of the products and reduces consumers' willingness to buy and use them. Utility Model Content

[0005] The purpose of the utility model is to overcome the shortcomings of existing ovens that discharge high-temperature oil smoke that affects the user's use space environment and user experience, and to provide a high-temperature oil smoke filtering device and an oven. The utility model can filter the oil smoke generated by ovens and ovens when cooking food before discharging it, and cool the high-temperature oil smoke before discharging it, which can effectively reduce the impact of such oil smoke on the indoor and outdoor environment.

[0006] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0007] A high-temperature oil fume filtering device, comprising:

[0008] A filter box is provided with an air inlet and an air outlet that pass through both ends of the filter box, and the air inlet includes an oil fume inlet and a cold air inlet located at the same end of the filter box;

[0009] A filter is disposed in the filter box and is located between the exhaust port and the air inlet;

[0010] The fan assembly is arranged in the cold air inlet and is used to introduce cold air.

[0011] High-temperature oil smoke enters through the oil smoke inlet and needs to be filtered by the filter in the filter box before it can reach the exhaust port of the filter box. The gas discharged from the exhaust port is already filtered clean gas. In addition, the present application also opens a cold air inlet on one side of the oil smoke inlet, and uses a fan assembly arranged in the cold air inlet to introduce cold air. This structure has two functions: first, the fan assembly continuously introduces cold air into the filter box, and the cold air and high-temperature oil smoke are mixed to form medium- and low-temperature mixed oil smoke, thereby reducing the temperature of the high-temperature oil smoke, so that it can be used in ovens with higher furnace temperature settings; second, the fan assembly introduces cold air and continuously blows it in, which accelerates the gas flow in the filter box and reduces the air pressure, thereby forming a suction effect on the oil smoke inlet arranged on the same side, which can accelerate the suction of high-temperature oil smoke from the oven cavity and has a good airflow promotion effect. The present application can filter the fumes generated by ovens and baking ovens when cooking food before discharging them, which can effectively reduce the impact of such fumes on indoor and outdoor environments. The gas after discharge has been cooled and the smoke has been filtered, which will not cause air pollution and local high temperature in the use space. In addition, the present application can be applied to baking ovens or baking ovens with higher upper temperature limits, with a wider range of applications and significant effects.

[0012] Furthermore, the fan assembly includes a motor and a fan blade connected to the output end of the motor. The motor is fixed to the port of the cold air inlet through a fixing plate. The fan blade is located in the port of the cold air inlet. An air flow hole is provided between the fixing plate and the end surface of the cold air inlet. In this way, the motor fixed to the end surface of the cold air port drives the fan blade to rotate continuously, and the external cold air is continuously drawn into the cold air inlet through the air flow hole. The structure is simple and effective, and does not need to occupy a large space.

[0013] Furthermore, the filter box is composed of a rectangular box body and a box body cover that can be detachably spliced, and the air inlet and the exhaust port are respectively located at the two ends of the length direction of the filter box. The detachable and spliced ​​rectangular box body and the box body cover can facilitate the disassembly and assembly of the filter therein and the assembly of the overall structure; the rectangular box body is set up with the air inlet and the exhaust port respectively located at the two ends of the length direction of the filter box so that the airflow can have a longer airway in the filter box, so that after the filter is arranged therein, the gas and the filter have more contact time, thereby improving the filtering effect; the detachable and spliced ​​filter box is designed to be a structure that consumers can disassemble and assemble. When the filter is dirty and the filtering function is significantly reduced after being used for a period of time, consumers can purchase a new filter module according to the instructions to replace it and restore the filtering performance of the filter.

[0014] Furthermore, the rectangular box body or the box body cover is provided with a connecting ear, and the connecting ear is also provided with a mounting hole for detachably connecting to the oven. The present application is fixed in the oven through the mounting hole on the connecting ear, and the modular design enables the present application to be integrated in a variety of ovens.

[0015] Furthermore, the filter is a honeycomb ceramic body, or an activated carbon filter block, or an activated carbon filter cotton block or a negative ion generator.

[0016] Furthermore, it also includes a cross-flow fan, and the air inlet end of the cross-flow fan is connected to the exhaust port of the filter box through a silicone outlet pipe. The cross-flow fan generally includes an air inlet end and an exhaust end. The airflow flows through the impeller and is affected by the blades twice, so the airflow can reach a long distance. The cross-flow fan is set to suck at the exhaust port. On the one hand, it can accelerate the gas flow rate in the filter box and speed up the filtering process. On the other hand, it can further cool and dissipate the heat of the sucked gas.

[0017] Furthermore, the exhaust end of the crossflow fan is also connected to an air guide chimney, which can adjust the gas exhaust direction according to the placement angle, so that the present application is suitable for ovens or baking ovens with different structures.

[0018] A baking oven comprises a furnace cavity and the above-mentioned high-temperature oil fume filtering device, wherein the oil fume inlet is connected to the furnace cavity.

[0019] Furthermore, the furnace cavity and the oil fume inlet are connected through an oil fume exhaust pipe, which is a metal pipe. The temperature of the smoke just discharged from the furnace cavity is high, and the metal oil fume exhaust pipe is used to ensure that it will not be damaged and increase its service life.

[0020] Furthermore, it also includes a heat insulation board attached to the outer wall of the oven cavity, and the filter box is detachably connected to the heat insulation board. The heat insulation board structure is a conventional design of the outer wall of the oven cavity. In this application, the filter box is fixed on the side with the heat insulation board, which can reduce the impact of the high temperature of the oven cavity on the temperature of the gas inside the filter box.

[0021] Compared with the prior art, the beneficial effects of the utility model are:

[0022] (1) The high-temperature oil smoke of the utility model enters through the oil smoke inlet and needs to be filtered by the filter in the filter box before it can reach the exhaust port of the filter box. The gas discharged from the exhaust port is already filtered clean gas. In addition, the utility model also opens a cold air inlet on one side of the oil smoke inlet, and uses a fan assembly arranged in the cold air inlet to introduce cold air. This structure has two functions: first, the fan assembly continuously introduces cold air into the filter box, and the cold air and the high-temperature oil smoke are mixed to form medium- and low-temperature mixed oil smoke, thereby reducing the temperature of the high-temperature oil smoke, so that it can be used in ovens with higher furnace temperature settings; second, the fan assembly introduces cold air and continuously blows it in, which accelerates the gas flow in the filter box and reduces the air pressure, thereby forming a suction effect on the oil smoke inlet arranged on the same side, which can accelerate the suction of high-temperature oil smoke from the furnace cavity and has a good airflow promotion effect.

[0023] (2) The utility model is applied to oven products. When cooking food, the fumes generated can be filtered before being discharged, which can effectively reduce the impact of such fumes on the indoor and outdoor environment. The gas after discharge has been cooled and the fume has been filtered, which will not cause air pollution and local high temperature in the use space. In addition, the oven using the device of the utility model can set a higher upper limit of the furnace temperature, making cooking more efficient. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] like Figures 1 to 3 As shown, a high-temperature oil fume filtering device comprises:

[0036] The filter box 1 is provided with an air inlet and an air outlet 13 which pass through both ends, and the air inlet includes an oil fume inlet 11 and a cold air inlet 12 which are located at the same end of the filter box 1;

[0038] The fan assembly 3 is disposed in the cold air inlet 12 and is used to introduce cold air.

[0039] High-temperature oil smoke enters through the oil smoke inlet 11 and needs to be filtered by the filter 2 in the filter box 1 before reaching the exhaust port 13 of the filter box 1. The gas discharged from the exhaust port 13 is already filtered clean gas. In addition, the present application also opens a cold air inlet 12 on one side of the oil smoke inlet 11, and uses the fan assembly 3 arranged in the cold air inlet 12 to introduce cold air. This structure has two functions: first, the fan assembly 3 continuously introduces cold air into the filter box 1, and the cold air and high-temperature oil smoke are mixed to form medium- and low-temperature mixed oil smoke, which reduces the temperature of the high-temperature oil smoke and can be used in ovens with higher furnace temperature settings; second, the fan assembly 3 introduces cold air and continuously blows it in, which accelerates the gas flow in the filter box 1 and reduces the air pressure, thereby forming a suction effect on the oil smoke inlet 11 arranged on the same side, which can accelerate the suction of high-temperature oil smoke from the oven cavity and has a good airflow promotion effect. The present application can filter the fumes generated by ovens and baking ovens when cooking food before discharging them, which can effectively reduce the impact of such fumes on indoor and outdoor environments. The gas after discharge has been cooled and the smoke has been filtered, which will not cause air pollution and local high temperature in the use space. In addition, the present application can be applied to baking ovens or baking ovens with higher upper temperature limits, with a wider range of applications and significant effects.

[0040] like Figure 3As shown, the fan assembly 3 includes a motor 31 and a fan blade 32 connected to the output end of the motor 31. The motor 31 is fixed to the port of the cold air inlet 12 through a fixing plate 33. The fan blade 32 is located in the port of the cold air inlet 12. An air flow hole 34 is provided between the fixing plate 33 and the end surface of the cold air inlet 12. In this way, the motor 31 fixed to the end surface of the port of the cold air inlet 12 drives the fan blade 32 to rotate continuously, and the external cold air is continuously drawn into the cold air inlet 12 through the air flow hole 34. The structure is simple and effective, and does not need to occupy a large space.

[0041] like Figure 2 and Figure 3 As shown, the filter box 1 is composed of a rectangular box body 14 and a box body cover 15 that can be detachably assembled, and the air inlet and the exhaust port 13 are respectively located at the two ends of the length direction of the filter box 1. The detachably assembled rectangular box body 14 and the box body cover 15 can facilitate the disassembly and assembly of the filter 2 therein and the assembly of the overall structure; the rectangular box body 14 is set and the air inlet and the exhaust port 13 are respectively located at the two ends of the length direction of the filter box 1 so that the oil fume airflow can have a longer airway in the filter box 1, so that after the filter 2 is arranged therein, the oil fume gas and the filter 2 have more contact time, thereby improving the filtering effect; the detachably assembled filter box 1 is designed to be a structure that can be disassembled and assembled by consumers. When the filter 2 is used for a period of time and becomes dirty and the filtering function is significantly reduced, consumers can purchase a new filter 2 module according to the instructions to replace it and restore the filtering performance of the filter 2.

[0042] like Figure 1 and Figure 4 As shown, the box cover 15 is provided with a connecting ear 16, and the connecting ear 16 is also provided with a mounting hole 17 for detachably connecting to the oven. The present invention is fixed in the oven through the mounting hole 17 on the connecting ear 16, and the modular design allows the present invention to be integrated in a variety of ovens.

[0043] In this embodiment, the filter 2 is an activated carbon filter cotton block.

[0044] Example 2

[0046] like Figure 4 As shown, a crossflow fan 4 is also included, and the air inlet end of the crossflow fan 4 is connected to the exhaust port 13 of the filter box 1 through a silicone outlet pipe 5. The crossflow fan 4 generally includes an air inlet end and an exhaust end. The airflow flows through the impeller and is affected by the blades twice, so the airflow can reach a long distance. The crossflow fan 4 is set to suck at the exhaust port 13. On the one hand, it can accelerate the gas flow rate in the filter box 1 and speed up the filtering process. On the other hand, it can further cool and dissipate the sucked gas.

The air guide chimney 6 can adjust the gas exhaust direction according to the placement angle, so that the present application is suitable for ovens or baking ovens with different structures.

[0048] High-temperature oil smoke enters through the oil smoke inlet 11 and needs to be filtered by the filter 2 in the filter box 1 before reaching the exhaust port 13 of the filter box 1. The gas discharged from the exhaust port 13 is already filtered clean gas. In addition, the present application also opens a cold air inlet 12 on one side of the oil smoke inlet 11, and uses the fan assembly 3 arranged in the cold air inlet 12 to introduce cold air. This structure has two functions: first, the fan assembly 3 continuously introduces cold air into the filter box 1, and the cold air and high-temperature oil smoke are mixed to form medium- and low-temperature mixed oil smoke, which reduces the temperature of the high-temperature oil smoke and can be used in ovens with higher furnace temperature settings; second, the fan assembly 3 introduces cold air and continuously blows it in, which accelerates the gas flow in the filter box 1 and reduces the air pressure, thereby forming a suction effect on the oil smoke inlet 11 arranged on the same side, which can accelerate the suction of high-temperature oil smoke from the oven cavity and has a good airflow promotion effect. The present application can filter the fumes generated by ovens and baking ovens when cooking food before discharging them, which can effectively reduce the impact of such fumes on indoor and outdoor environments. The gas after discharge has been cooled and the smoke has been filtered, which will not cause air pollution and local high temperature in the use space. In addition, the present application can be applied to baking ovens or baking ovens with higher upper temperature limits, with a wider range of applications and significant effects.
