Abstract
Description
Technical Field
[0001] The present application relates to the technical field of cooking appliances, and in particular to a filtering device and a household device. Background Art
[0002] Air fryers or small kitchen appliances with frying and stir-frying functions will produce fumes and smoke when working. The exhausted fumes and smoke will have an impact on the environment and affect the user experience. Utility Model Content
[0003] The present application aims to solve at least one of the technical problems existing in the prior art or related art.
[0004] To this end, a first aspect of the present application provides a filtering device.
[0005] A second aspect of the present application proposes a household device.
[0006] In view of this, the first aspect of the present application proposes a filtering device, comprising: a shell, on which a first air outlet and a second air outlet are provided, and an air duct is provided in the shell, and the air duct connects the first air outlet and the second air outlet; a fan, arranged in the air duct, and the fan is used to guide air from the first air outlet to the second air outlet; and a filtering structure, arranged in the air duct.
[0007] A filtering device provided in the present application includes a housing, a fan and a filtering structure.
[0008] The fan and the filter device are both arranged in the air duct. That is to say, when the filter device is working, the air in the environment flows into the air duct from the first air port under the action of the fan, and is discharged from the filter device from the second air port after flowing through the filter structure. The filter device can filter out the smoke and reduce the smoke discharged into the room, so as to achieve the purpose of filtering the smoke generated when the cooking utensils are working, and avoid the situation that the smoke spreads indoors, and then the oil stains adhere to the furniture or the smoke and odor adhere to the clothes, thereby reducing the impact on the indoor environment.
[0009] Optionally, the filter device is a structure independent of the cooking utensil. When the filter device is needed to filter oil smoke and fumes, the filter device can be placed next to the cooking utensil to be filtered. When the cooking utensil is working, the filter device works so that the first air outlet draws air from the cooking utensil to draw the fumes generated by the cooking utensil into the filter device, and then discharges them along at least the second air outlet. This setting can achieve the purpose of directional emission of filtered gas. For example, the second air outlet can be set toward the window, or the second air outlet can be set toward the balcony, or the second air outlet can be set in a direction away from the crowd, so as to avoid the spread of water mist and oil smoke in the room.
[0010] Optionally, the cooking utensil includes a filtering device, that is, the filtering device is a component of the cooking utensil, and the filtering device has the function of filtering smoke generated by the cooking utensil during cooking, so that the filtered gas is discharged into the room, thereby reducing the impact on the indoor environment.
[0011] It is understandable that the filter device includes a fan, so that airflow can be drawn into the filter device in a large amount and effectively, and discharged through the filter structure, thereby ensuring the filtering efficiency.
[0012] According to the above-mentioned filtering device of the present application, the following additional technical features may also be provided:
[0013] In some embodiments, optionally, the filtering structure is located between the fan and the second air outlet.
[0014] In this embodiment, the positional relationship between the filter structure, the fan and the second air outlet is further defined, so that the filter structure is located between the fan and the second air outlet. When the filter device is working, the air in the environment flows into the air duct from the first air outlet under the action of the fan, and is discharged from the filter device through the second air outlet after passing through the filter structure. It can be seen that the gas flowing through the filter device must pass through the filter structure before being discharged from the filter device through the second air outlet. The filter device can filter out smoke and reduce smoke discharged into the room.
[0015] In some embodiments, optionally, the filtering structure is located at the second air outlet.
[0016] In this embodiment, the positional relationship between the filter structure and the second air outlet is further limited, so that the filter structure is located at the second air outlet to reduce the distance between the filter structure and the second air outlet, thereby reducing the probability of gas flowing to the second air outlet through the gap between the filter structure and the second air outlet without being filtered by the filter structure, which is beneficial to improving the filtering efficiency of the filtering device.
[0017] In some embodiments, optionally, the filtering structure covers the second air outlet.
[0018] In this embodiment, the matching structure of the filter structure and the second air outlet is further defined so that the filter structure covers the second air outlet, or in other words, the outer edge of the filter structure is located outside the wall of the second air outlet. This arrangement increases the matching area of the filter structure and the second air outlet, and prevents the gas from flowing to the second air outlet through the gap between the filter structure and the second air outlet without being filtered by the filter structure.
[0019] Optionally, the filtering structure is arranged to fit the second air outlet.
[0020] In some embodiments, optionally, the distance from at least a portion of the first air outlet to the bottom of the shell is greater than the distance from the second air outlet to the bottom of the shell.
[0021] In this embodiment, the positional relationship between the first air outlet and the second air outlet is further defined, so that the distance from at least a portion of the first air outlet to the bottom of the housing is greater than the distance from the second air outlet to the bottom of the housing. That is, the distance from a portion of the first air outlet to the bottom of the housing is greater than the distance from the second air outlet to the bottom of the housing. Alternatively, the distance from the first air outlet to the bottom of the housing is greater than the distance from the second air outlet to the bottom of the housing.
[0022] This arrangement is conducive to increasing the fan-shaped air inlet area of the first air outlet, so that the smoke can be sucked into the filter device at the first time, which is conducive to improving the filtering effect of the filter device.
[0023] At the same time, this arrangement reduces the height of the second air outlet, so that the filtered airflow can be discharged at a lower height. Due to the temperature angle of the smoke and oil smoke generated when the cooking appliance is working, the filtered gas is discharged at a lower position, and the gas can flow close to the carrier (such as a desktop or cabinet surface), so that the user can be avoided from being scalded, which is conducive to improving the safety and reliability of product use.
[0024] In some embodiments, optionally, the air duct includes: a first guide section, the fan is arranged in the first guide section; a second guide section, the second guide section is connected between the first guide section and the second air outlet, the first guide section is connected between the first air outlet and the second guide section, and the filtering structure is arranged in the second guide section; along the direction of the first guide section away from the first air outlet, the flow cross-sectional area of the first guide section first increases and then decreases.
[0025] In this embodiment, the structure of the air duct is further defined, so that the air duct includes a first guide section and a second guide section, the second guide section is connected between the first guide section and the second air outlet, and the first guide section is connected between the first air outlet and the second guide section. The fan is arranged in the first guide section, and the filter structure is arranged in the second guide section.
[0026] Along the direction from the first air outlet to the first guide section, that is, along the direction of the first guide section away from the first air outlet, the flow cross-sectional area of the first guide section first increases and then decreases. The first guide section is sectioned along the extension direction perpendicular to the first air outlet (or it can be said that along the direction perpendicular to the first air outlet to the fan), and in the section, the area of the area enclosed by the contour line of the wall of the first guide section is the flow cross-sectional area of the first guide section.
[0027] The flow cross-sectional area of the first air outlet is smaller than the flow cross-sectional area of the portion of the first guide section located between the first air outlet and the second guide section. The flow cross-sectional area of the connection between the first guide section and the second guide section is smaller than the flow cross-sectional area of the portion of the first guide section located between the first air outlet and the second guide section.
[0028] In this way, the airflow enters the first guide section with a larger flow cross-sectional area from the first air port with a smaller flow cross-sectional area, and then flows from the connection between the first guide section with a smaller flow cross-sectional area and the second guide section to the second guide section. This setting can achieve the purpose of pressurization and can form a fan-shaped air suction area on the outside of the shell. In this way, the amount of air flowing into the filter device can be increased, which is conducive to improving the filtering efficiency of the filter device.
[0029] In some embodiments, optionally, along the direction of the second guide section approaching the second air outlet, the flow cross-sectional area of the second guide section gradually increases.
[0030] In this embodiment, the shape of the second guide section is further defined, and the flow cross-sectional area of the second guide section gradually increases in the direction of the second guide section approaching the second air outlet. The second guide section is sectioned along a direction perpendicular to the extension of the second guide section (or, in other words, along a direction perpendicular to the second guide section approaching the second air outlet), and in the section, the area of the region enclosed by the contour line of the wall of the first guide section is the flow cross-sectional area of the second guide section.
[0031] This setting can achieve fan-shaped area air supply and increase the radiation area of the airflow. In this way, the airflow can be effectively delivered to the filter structure, so that the filter structures at different positions can effectively and evenly contact the airflow, which can increase the frequency of contact between the filter structure and the airflow at different positions, and can make full use of the filter device, which is beneficial to improve the filter efficiency of the filter device.
[0032] In some embodiments, optionally, the filtering structure includes: a catalytic part, the catalytic part is provided with a plurality of flow channels arranged at intervals, and the flow channels are arranged along the air duct close to the second air outlet; and a heating element, the heating element is used to supply heat to the catalytic part.
[0033] In this embodiment, the composition of the filter structure is defined, specifically, the filter structure includes a catalyst part and a heating element. When the filter device is working, the heating element can generate heat, and the generated heat can heat the catalyst part. The catalyst part can decompose and filter the oil smoke, carbon black and other materials in the airflow under the action of high temperature to decompose the catalytic smoke and oil smoke, so as to ensure the cleanliness and harmlessness of the airflow discharged by the filter device.
[0034] It can be understood that the catalyst part is provided with a plurality of flow channels, and the plurality of flow channels are arranged at intervals, and each flow channel is arranged along the direction from the air duct to the second air outlet, that is, each flow channel is arranged along the direction of the air duct close to the second air outlet. This arrangement is conducive to increasing the contact area and contact angle between the airflow and the catalyst part, so that the smoke can fully contact the catalyst part, which is conducive to improving the filtration efficiency of the filtration structure.
[0035] In some embodiments, optionally, the heating element is located on a side of the catalyst portion away from the second air outlet; the catalyst portion includes a three-way catalyst module.
[0036] In this embodiment, the positional relationship between the heating element, the catalytic part and the second air outlet is defined so that the heating element is located on the side of the catalytic part away from the second air outlet. When the filter device is working, the heating element can generate heat, and the generated heat can heat the flue gas flowing to the catalytic part through the air duct, and the generated heat can also heat the catalytic part. The temperature of the catalytic part and the flue gas when they are in contact can be guaranteed, which is conducive to improving the filtering effect.
[0037] In addition, the catalyst part includes a three-way catalyst module, that is, the type of the catalyst part is limited. The lower heating element (such as an electric heating tube, an electric heating plate) heats the catalyst part, and the heating temperature of the heating element is 350°C, so that the smoke completely passes through the electric heating tube and is discharged through the three-way catalyst module, becoming colorless and odorless gas, which can solve the smoke problem.

[0040] It can be understood that the guide plate group is arranged around the first air outlet, and the guide plate group is arranged around the second air outlet. The inner surface of the guide plate group encloses the air outlet, and the guide plate group has the function of limiting the flow path of the airflow.
[0041] In some embodiments, optionally, the outer surface of the guide plate group and the inner surface of the outer shell are arranged at intervals to enclose a heat-insulating cavity.
[0042] In this embodiment, the matching structure of the guide plate group and the shell is further defined, so that the outer surface of the guide plate group and the inner surface of the shell are arranged at intervals to enclose a heat-insulating cavity. The heat-insulating cavity has a heat-insulating effect, which is conducive to reducing the temperature of the outer surface of the shell, so that the user will not be scalded, which is conducive to improving the safety and reliability of the use of the filtering device.
[0043] In some embodiments, optionally, the filtering device further includes: a bracket, through which the filtering structure is connected to the guide plate group; a thermostat, which is connected to the guide plate group, and the thermostat is used to detect the temperature of the filtering structure; and a ground foot, which is located on one side of the outer shell and connected to the bottom of the outer shell.
[0044] In this embodiment, the structure of the filter device is further defined so that the filter device further includes a bracket, a temperature controller and a foot.
[0045] The filter structure is connected to the guide plate group through the bracket, that is, the bracket has the function of supporting and fixing the filter structure, and can ensure the matching structure of the filter structure and the air duct. Optionally, the heating element is connected to the bracket.
[0046] The thermostat is connected to the guide plate group.

In this way, the filtration efficiency of the filter structure can be guaranteed, and damage to the filter structure due to excessively high temperature of the filter structure can be avoided, thereby ensuring the safety and reliability of the operation of the filter device.
[0047] The foot is located on one side of the shell and connected to the bottom of the shell, and the foot has the function of supporting the shell, so that there is a gap between the shell and the mounting carrier, which is beneficial to the heat dissipation of the filter device and reduces the occurrence of scalding the mounting carrier.
[0048] In some embodiments, optionally, the outer shell includes: a base, the base includes a first vertical plate and a second vertical plate arranged opposite to and at intervals, the height of the first vertical plate is higher than the height of the second vertical plate, the first vertical plate is provided with a first air outlet, and the second vertical plate is provided with a second air outlet; a top cover, the top cover is bent and arranged to form a stepped structure, the top cover is connected between the first vertical plate and the second vertical plate; two side panels, each side panel is connected between the base and the top cover, and the two side panels are arranged opposite to each other.

[0052] At the same time, the bending arrangement of the top cover is beneficial to improving the structural strength of the top cover, and further helps to improve the overall structural strength of the filtering device.

DETAILED DESCRIPTION
[0081] In order to more clearly understand the above-mentioned purposes, features and advantages of the present application, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.
[0082] In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present application is not limited to the specific embodiments disclosed below.
[0083] Refer to the following Figures 1 to 14 A filtering device 10 and a household device 44 according to some embodiments of the present application.
[0084] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 , Fig.10 , Fig.11 and Fig.12 As shown, a filtering device 10 according to some embodiments of the present application includes a housing 100 , a fan 200 and a filtering structure 300 .
[0085] The housing 100 is provided with a first air outlet 110 and a second air outlet 120 .
[0086] An air duct 130 is disposed in the housing 100 .
[0087] The air duct 130 communicates with the first air outlet 110 and the second air outlet 120 .
[0088] The fan 200 is disposed in the air duct 130 , and is used to guide air from the first air outlet 110 to the second air outlet 120 .
[0089] The filtering structure 300 is disposed in the air duct 130 .
[0090] In this embodiment, the filter device 10 includes a housing 100 , a fan 200 and a filter structure 300 .
[0091] The fan 200 and the filter device 10 are both arranged in the air duct 130. That is to say, when the filter device 10 is working, the air in the environment flows into the air duct 130 from the first air port 110 under the action of the fan 200, flows through the filter structure 300, and then is discharged from the filter device 10 from the second air port 120. The filter device 10 can filter out the smoke and reduce the smoke discharged into the room, so as to achieve the purpose of filtering the smoke generated when the cooking utensils are working, and can prevent the smoke from spreading indoors, thereby preventing the oil stains from adhering to the furniture or the smoke and odor from adhering to the clothes, thereby reducing the impact on the indoor environment.
[0092] Optionally, the filter device 10 is a structure independent of the cooking utensil. When the filter device 10 is needed to filter oil smoke and fumes, the filter device 10 can be placed next to the cooking utensil to be filtered. When the cooking utensil is working, the filter device 10 works so that the first air outlet 110 draws air from the cooking utensil to draw the fumes generated by the cooking utensil into the filter device 10, and then discharges them at least along the second air outlet 120. This setting can achieve the purpose of directional emission of filtered gas. For example, the second air outlet 120 can be set toward the window, or the second air outlet 120 can be set toward the balcony, or the second air outlet 120 can be set in a direction away from the crowd, so as to avoid the spread of water mist and oil smoke in the room.
[0093] Optionally, the cooking utensil includes a filter device 10, that is, the filter device 10 is a component of the cooking utensil, and the filter device 10 has the function of filtering smoke generated by the cooking utensil during cooking, so that the filtered gas is discharged into the room, thereby reducing the impact on the indoor environment.
[0094] It can be understood that the filter device 10 includes the fan 200, so that airflow can be drawn into the filter device 10 in a large amount and effectively, and discharged through the filter structure 300, thereby ensuring the filtering efficiency.
[0095] Optionally, the fan 200 includes a turbocharger fan.
[0096] In some embodiments, optionally, Figure 6 As shown, the filter structure 300 is located between the fan 200 and the second air outlet 120 .
[0097] In this embodiment, the positional relationship between the filter structure 300, the fan 200 and the second air outlet 120 is further defined, so that the filter structure 300 is located between the fan 200 and the second air outlet 120. When the filter device 10 is working, the air in the environment flows into the air duct 130 from the first air outlet 110 under the action of the fan 200, and is discharged from the filter device 10 from the second air outlet 120 after passing through the filter structure 300. It can be seen that the gas flowing through the filter device 10 must pass through the filter structure 300 before being discharged from the filter device 10 from the second air outlet 120, and the filter device 10 can filter out the smoke and reduce the smoke discharged into the room.
[0098] In some embodiments, optionally, Figure 4 and Figure 6 As shown, the filtering structure 300 is located at the second air outlet 120 .
[0099] In this embodiment, the positional relationship between the filter structure 300 and the second air port 120 is further limited, so that the filter structure 300 is located at the second air port 120 to reduce the distance between the filter structure 300 and the second air port 120. In this way, the probability of gas flowing to the second air port 120 through the gap between the filter structure 300 and the second air port 120 without being filtered by the filter structure 300 can be reduced. This is conducive to improving the filtering efficiency of the filter device 10.
[0100] In some embodiments, optionally, Figure 4 and Figure 6 As shown, the filter structure 300 covers the second air outlet 120 .
[0101] In this embodiment, the matching structure of the filter structure 300 and the second air outlet 120 is further defined, so that the filter structure 300 covers the second air outlet 120, or in other words, the outer edge of the filter structure 300 is located outside the wall of the second air outlet 120. This arrangement increases the matching area of the filter structure 300 and the second air outlet 120, and prevents the gas from flowing to the second air outlet 120 through the gap between the filter structure 300 and the second air outlet 120 without being filtered by the filter structure 300.
[0102] Optionally, the filter structure 300 is disposed in close contact with the second air outlet 120 .
[0103] In some embodiments, optionally, Figure 6 As shown, the distance from at least a portion of the first air outlet 110 to the bottom 140 of the housing is greater than the distance from the second air outlet 120 to the bottom 140 of the housing.
[0104] In this embodiment, the positional relationship between the first air outlet 110 and the second air outlet 120 is further defined, so that the distance from at least a portion of the first air outlet 110 to the bottom 140 of the housing is greater than the distance from the second air outlet 120 to the bottom 140 of the housing. That is, the distance from a portion of the first air outlet 110 to the bottom 140 of the housing is greater than the distance from the second air outlet 120 to the bottom 140 of the housing. Alternatively, the distance from the first air outlet 110 to the bottom 140 of the housing is greater than the distance from the second air outlet 120 to the bottom 140 of the housing.
[0105] This arrangement is beneficial to increasing the fan-shaped air inlet area of the first air outlet 110 , so that smoke can be sucked into the filter device 10 at the first time, which is beneficial to improving the filtering effect of the filter device 10 .
[0106] At the same time, this arrangement reduces the height of the second air outlet 120, so that the filtered airflow can be discharged at a lower height. Due to the temperature angle of the smoke and oil smoke generated when the cooking appliance is working, the filtered gas is discharged at a lower position, and the gas can flow close to the installation carrier (such as a desktop or cabinet surface), so that the user can be prevented from being scalded, which is conducive to improving the safety and reliability of product use.
[0107] In some embodiments, optionally, Figure 6 As shown, the air duct 130 includes a first air guiding segment 132 and a second air guiding segment 134 .
[0108] The fan 200 is disposed in the first flow guiding section 132 .
[0109] The second guide section 134 is connected between the first guide section 132 and the second air outlet 120 , and the first guide section 132 is connected between the first air outlet 110 and the second guide section 134 .
[0110] The filtering structure 300 is disposed in the second flow guiding section 134 .
[0111] In the direction of the first flow guiding section 132 away from the first air outlet 110 , the flow cross-sectional area of the first flow guiding section 132 increases first and then decreases.
[0112] In this embodiment, the structure of the air duct 130 is further defined, so that the air duct 130 includes a first guide section 132 and a second guide section 134, the second guide section 134 is connected between the first guide section 132 and the second air outlet 120, and the first guide section 132 is connected between the first air outlet 110 and the second guide section 134.
[0113] The fan 200 is disposed in the first flow guiding section 132 , and the filter structure 300 is disposed in the second flow guiding section 134 .
[0114] Along the direction from the first air outlet 110 to the first guide section 132, that is, along the direction of the first guide section 132 away from the first air outlet 110, the flow cross-sectional area of the first guide section 132 first increases and then decreases. The first guide section 132 is sectioned along the extending direction perpendicular to the first air outlet 110 (or, in other words, along the direction perpendicular to the first air outlet 110 to the fan 200). In the section, the area of the region enclosed by the contour line of the wall of the first guide section 132 is the flow cross-sectional area of the first guide section 132.
[0115] The flow cross-sectional area of the first air port 110 is smaller than the flow cross-sectional area of the portion of the first guide section 132 located between the first air port 110 and the second guide section 134. The flow cross-sectional area of the connection between the first guide section 132 and the second guide section 134 is smaller than the flow cross-sectional area of the portion of the first guide section 132 located between the first air port 110 and the second guide section 134.
[0116] In this way, the airflow enters the first guide section 132 with a larger flow cross-sectional area from the first air port 110 with a smaller flow cross-sectional area, and then flows from the connection between the first guide section 132 with a smaller flow cross-sectional area and the second guide section 134 to the second guide section 134. This arrangement can achieve the purpose of pressurization and can form a fan-shaped air suction area outside the housing 100. In this way, the amount of air flowing into the filter device 10 can be increased, which is conducive to improving the filtering efficiency of the filter device 10.
[0117] In some embodiments, optionally, along the direction of the second guide segment 134 approaching the second air outlet 120 , the flow cross-sectional area of the second guide segment 134 gradually increases.
[0118] In this embodiment, the shape of the second guide section 134 is further defined, and the flow cross-sectional area of the second guide section 134 gradually increases along the direction from the second guide section 134 to the second air outlet 120, that is, along the direction of the second guide section 134 approaching the second air outlet 120. The second guide section 134 is sectioned along the extending direction perpendicular to the second guide section 134 (or, in other words, along the direction perpendicular to the second guide section 134 approaching the second air outlet 120). In the section, the area of the region enclosed by the contour line of the wall of the first guide section 132 is the flow cross-sectional area of the second guide section 134.
[0119] This setting can realize fan-shaped area air supply and increase the radiation area of the airflow. In this way, the airflow can be effectively delivered to the filter structure 300, so that the filter structures 300 at different positions can effectively and evenly contact the airflow, which can increase the frequency of contact between the filter structure 300 and the airflow at different positions, and can make full use of the filter device 300, which is beneficial to improve the filtration efficiency of the filter device 10.

[0124] In this embodiment, the composition of the filter structure 300 is defined, specifically, the filter structure 300 includes a catalytic part 310 and a heating element 320. When the filter device 10 is working, the heating element 320 can generate heat, and the generated heat can heat the catalytic part 310. The catalytic part 310 can decompose and filter the oil smoke, carbon black and other materials in the airflow under the action of high temperature to decompose the catalytic smoke and oil smoke, so as to ensure the cleanliness and harmlessness of the airflow discharged by the filter device 10.
[0125] It can be understood that the catalyst section 310 is provided with a plurality of flow channels 312, and the plurality of flow channels 312 are arranged at intervals, and each flow channel 312 is arranged along the air duct 130 close to the second air outlet 120. This arrangement is beneficial to increasing the contact area and contact angle between the airflow and the catalyst section 310, so that the smoke can fully contact the catalyst section 310, which is beneficial to improving the filtering efficiency of the filtering structure 300.
[0126] In some embodiments, optionally, Figure 6As shown, the heating element 320 is located on a side of the catalytic portion 310 away from the second air outlet 120; the catalytic portion 310 includes a three-way catalyst module.
[0127] In this embodiment, the positional relationship between the heating element 320, the catalytic part 310 and the second air outlet 120 is defined so that the heating element 320 is located on the side of the catalytic part 310 away from the second air outlet 120. When the filter device 10 is working, the heating element 320 can generate heat, and the generated heat can heat the flue gas flowing to the catalytic part 310 through the air duct 130, and the generated heat can also heat the catalytic part 310. The temperature of the catalytic part 310 when in contact with the flue gas can be ensured, which is conducive to improving the filtering effect.
[0128] In addition, the catalyst part 310 includes a three-way catalyst module, that is, the type of the catalyst part 310 is limited. The lower heating element 320 (such as an electric heating tube, an electric heating plate) heats the catalyst part 310, and the heating temperature of the heating element 320 is 350° C., so that the smoke completely passes through the electric heating tube and is discharged through the three-way catalyst module, and becomes colorless and odorless gas, which can solve the smoke problem.
[0129] In some embodiments, optionally, Figure 6 and Figure 7 As shown, the housing 100 includes an outer shell 150 and a guide plate set 160 .

[0166] like Fig.13 and Fig.14 As shown, a household device 44 according to some other embodiments of the present application includes: a carrier 22; and a filter device 10 as in any of the above embodiments, wherein the carrier 22 is used for installation and positioning of the filter device 10.
[0167] The household device 44 provided by the present invention comprises a carrier 22 and a filter device 10 as in any of the above embodiments, and therefore has all the beneficial effects of the above filter device 10, which will not be described one by one here.
[0168] In some embodiments, optionally, Fig.13 As shown, the carrier 22 includes a cooking utensil 33 ; the filter device 10 is disposed in the cooking utensil 33 .
[0169] In this embodiment, the type of the carrier 22 is limited so that the carrier 22 includes a cooking utensil 33. The filter device 10 is disposed on the cooking utensil 33, such as the filter device 10 is disposed on the cooking utensil 33, such as at least a portion of the filter device 10 is disposed in the cooking utensil 33. The filter device 10 has the function of filtering the smoke generated by the cooking utensil 33 during cooking, so that the filtered gas is discharged into the room, thereby reducing the impact on the indoor environment.
[0170] In some embodiments, optionally, Fig.14 As shown, the carrier 22 comprises a cabinet, a mounting stand or a mounting table.
[0171] In this embodiment, the type of the carrier 22 is defined such that the carrier 22 includes a cabinet, a mounting platform, or a mounting table. That is, the carrier 22 includes any one of the following: a cabinet, a mounting platform, and a mounting table.

[0173] When the filter device 10 is needed to filter oil smoke and fumes, the filter device 10 can be placed on the carrier 22 and located next to the cooking utensil to be filtered. When the cooking utensil is working, the filter device 10 works so that the first air outlet 110 draws air from the cooking utensil to draw the fumes generated by the cooking utensil into the filter device 10, and then discharges the fumes along at least the second air outlet 120. This setting can achieve the purpose of directional emission of filtered gas. For example, the second air outlet 120 can be directed toward the window, or the second air outlet 120 can be directed toward the balcony, or the second air outlet 120 can be directed away from the crowd to avoid the spread of water mist and oil smoke in the room.
[0174] In some embodiments, optionally, Fig.14 As shown, the filter device 10 is movably disposed on a carrier 22 .
[0175] In this embodiment, the matching structure of the filter device 10 and the carrier 22 is further defined, so that the filter device 10 can be movably arranged on the carrier 22. For example, the filter device 10 can be moved relative to the carrier 22 by the user manually moving the filter device 10. For example, the filter device 10 is provided with a roller, and the filter device 10 can be moved relative to the carrier 22 by the roller.
[0176] The assembly process of the filter device 10 is as follows:
[0177] 1. On the fan 200, an upper guide plate 162, a lower guide plate 164, a left guide plate 166 and a right guide plate 168 of the guide plate group 160 are provided. Any one of the upper guide plate 162, the lower guide plate 164, the left guide plate 166 and the right guide plate 168 is an aluminum plate. Any two adjacent ones of the upper guide plate 162, the lower guide plate 164, the left guide plate 166 and the right guide plate 168 are connected by rivets 800.
[0178] 2. The bracket 400 is installed on the electric heating tube, and the bracket 400 is assembled to the left guide plate 166 and the right guide plate 168 through rivets 800.
[0179] 3. Install the thermostat 500 on the left air guide plate through the rivets 800, and install the internal wires and power cord.
[0180] 4. Install the three-way catalyst module, install the base 152, and lock it on the guide plate assembly 160 and the fan 200 with screws 900.
[0181] 5. Install the top cover 154 and lock it on the base 152 with screws 900.
[0182] 6. Install the two side panels 156 and lock them on the base 152 and the top cover 154 using screws 900.
[0183] 7. Install the 600 anchors.
[0184] The filter device 10 of the present application can be used as an independent module and embedded in the chimney alone to filter and eliminate the generated smoke.

[0187] The filter device 10 includes a housing 100 , a fan 200 and a filter structure 300 .
[0188] The fan 200 and the filter device 10 are both arranged in the air duct 130, wherein the filter structure 300 is located between the fan 200 and the second air port 120. That is to say, when the filter device 10 is working, the air in the environment flows into the air duct 130 from the first air port 110 under the action of the fan 200, and is discharged from the filter device 10 from the second air port 120 after passing through the filter structure 300. It can be seen that the gas flowing through the filter device 10 must pass through the filter structure 300 before being discharged from the filter device 10 from the second air port 120. The filter device 10 can filter out the smoke and reduce the smoke discharged into the room, so as to achieve the purpose of filtering the smoke generated when the cooking utensils are working, and can avoid the situation that the smoke spreads indoors, and then the oil stains are attached to the furniture or the smoke and odors are attached to the clothes, thereby reducing the impact on the indoor environment.
[0189] Optionally, the filter device 10 is a structure independent of the cooking utensil. When the filter device 10 is needed to filter oil smoke and fumes, the filter device 10 can be placed next to the cooking utensil to be filtered. When the cooking utensil is working, the filter device 10 works so that the first air outlet 110 draws air from the cooking utensil to draw the fumes generated by the cooking utensil into the filter device 10, and then discharges them at least along the second air outlet 120. This setting can achieve the purpose of directional emission of filtered gas. For example, the second air outlet 120 can be set toward the window, or the second air outlet 120 can be set toward the balcony, or the second air outlet 120 can be set in a direction away from the crowd, so as to avoid the spread of water mist and oil smoke in the room.
[0190] Optionally, the cooking utensil includes a filter device 10, that is, the filter device 10 is a component of the cooking utensil, and the filter device 10 has the function of filtering smoke generated by the cooking utensil during cooking, so that the filtered gas is discharged into the room, thereby reducing the impact on the indoor environment.
[0191] It can be understood that the filter device 10 includes the fan 200, so that airflow can be drawn into the filter device 10 in a large amount and effectively, and discharged through the filter structure 300, thereby ensuring the filtering efficiency.
