[0044] See also Figure 1-Figure 4 The oil fume purification device 100 of the embodiment of the present application includes a fan assembly 10, a water guide member 20 and a filter assembly 30. The fan assembly 10 has an air inlet 11 and an air outlet 12. The fan assembly 10 is used to form an airflow flowing from the air inlet 11 to the air outlet 12; the water guide member 20 is arranged at the air inlet 11 of the fan assembly 10, and the water guide member 20 is formed with a receiving groove 201. The water guide member 20 is formed with a plurality of through holes 203, and the through holes 203 connect the air inlet 11 with the receiving groove 201; the filter assembly 30 is arranged in the receiving groove 201, and the filter assembly 30 is used to filter and condense the oil fume and form condensed water, and allow the filtered gas to pass through the receiving groove 201 and the through holes 203 in sequence and then enter the air inlet 11.

[0045] In this way, the through hole 203 of the water guide member 20 connects the accommodating groove 201 and the air inlet 11 of the fan assembly 10, so that the water guide member 20 can prevent foreign matter and condensed water from entering the fan assembly 10 while the gas filtered by the filter assembly 30 can enter the interior of the fan assembly 10 from the through hole 203. Multiple through holes 203 can increase the ventilation area, thereby increasing the air intake of the oil fume purification device 100 and improving the purification efficiency of the oil fume purification device 100.

[0046] Specifically, the oil fume purification device 100 is a kitchen device for purifying the kitchen environment. The oil fume purification device 100 is installed next to the kitchen stove, and can quickly extract the waste from the stove combustion and the oil fume harmful to the human body generated during the cooking process, and discharge them outdoors, while condensing and collecting the oil fume, reducing pollution and purifying the air. The oil fume purification device 100 can be a range hood, including an upward suction type, a downward suction type, a side suction type, etc.

[0047] The fan assembly 10 provides power for the flow of oil smoke, so that the oil smoke flows from the air inlet 11 to the air outlet 12 along with the air flow, thereby exhausting the oil smoke to the outside. In a downdraft range hood, the air inlet 11 is located above the air outlet 12. The purification speed of the oil fume purification device 100 can be determined by the speed of the fan assembly 10. When the fan assembly 10 runs faster, the flow speed of the air flow is faster, the amount of oil smoke extracted per unit time is larger, and the oil fume purification device 100 has a higher efficiency in purifying oil smoke.

[0048] The water guide 20 is arranged at the air inlet 11 of the fan assembly 10, and the water guide 20 may be partially arranged at the air inlet 11, for example, the water guide 20 passes through the air inlet 11, and the bottom of the water guide 20 contacts the electrical components located inside the fan assembly 10 below the air inlet 11. The inner surface of the water guide 20 forms a receiving groove 201, and the filter assembly 30 is accommodated in the receiving groove 201 along the height direction. The filter assembly 30 can be detachably connected to the water guide 20 by means of threaded connection, snap connection, etc. The bottom surface of the receiving groove 201 can be a plane or an inclined surface. The through hole 203 can be formed by eliminating part of the material on the outer surface of the water guide 20 toward the inner surface, and the shape, size, number and position of the through hole 203 can be designed according to actual needs.

[0049] The filter assembly 30 can be a mesh structure with filter holes, or a combination of multiple mesh structures with filter holes. The material of the filter assembly 30 can be a multi-layered metal flat mesh, a metal wire mesh, etc., or a non-metallic mesh. The filter assembly 30 can have an arc-shaped bottom surface or a rectangular bottom surface, and the bottom surface of the filter assembly 30 is spaced from the bottom surface of the receiving groove 201. When the oil smoke passes through the filter assembly 30, the water vapor and grease in the oil smoke are captured by the filter holes and condensed and drip into the water guide 20.

[0050] See also Figure 5 In some embodiments, the plurality of through holes 203 have a plurality of different air outlet directions.

[0051] In this way, the gas can enter the fan assembly 10 from different directions through the multiple through holes 203, thereby improving the dispersion of the gas, reducing the heat accumulation of the gas in the fan assembly 10, and preventing the temperature increase in the fan assembly 10 from affecting the operation of the fan assembly 10.

[0052] Specifically, the through hole 203 may be provided on the bottom surface of the water guiding member 20 , may be provided on the side surface of the water guiding member 20 , or may be provided on both the bottom surface and the side surface of the water guiding member 20 .

[0053] See also Figure 5In some embodiments, the water guide 20 includes a bottom wall 23, a first side wall 24, a second side wall 25 and a third side wall 26, the third side wall 26 is located between the first side wall 24 and the second side wall 25, the bottom wall 23 forms a bottom surface of the accommodating groove 201 and includes a first wall 27 and a second wall 28, the first wall 27 connects the first side wall 24 and the third side wall 26, the second wall 28 connects the second side wall 25 and the third side wall 26, the first side wall 24, the second side wall 25 and the third side wall 26 are all formed with a plurality of through holes 203, and the plurality of through holes 203 are arranged at intervals along the length direction of the water guide 20.

[0054] In this way, the gas can enter the fan assembly 10 from three directions: the first side wall 24, the second side wall 25 and the third side wall 26, thereby improving the dispersion of the gas and preventing foreign matter and condensed water from entering the fan assembly 10 while ensuring the air intake of the fan assembly 10.

[0055] Specifically, the bottom wall 23, the first side wall 24, the second side wall 25 and the third side wall 26 can be integrally injection molded, or can be connected by gluing, welding or mechanical connection. The bottom wall 23 can be rectangular, the first side wall 24 and the second side wall 25 can be trapezoidal, and the third side wall 26 can be a parallelogram. The first end wall 21, the second end wall 22, the bottom wall 23, the first side wall 24, the second side wall 25 and the third side wall 26 together form the receiving groove 201.

[0056] The through holes 203 penetrate the first side wall 24, the second side wall 25 and the third side wall 26 along the thickness direction of the first side wall 24, the second side wall 25 and the third side wall 26. The shapes and numbers of the through holes 203 on the first side wall 24, the second side wall 25 and the third side wall 26 may be the same or different. For example, 27 circular through holes 203 are formed on the first side wall 24, the second side wall 25 and the third side wall 26, or 27 circular through holes 203 are formed on the first side wall 24, 25 rectangular through holes 203 are formed on the second side wall 25, and 29 elliptical through holes 203 are formed on the third side wall 26.

[0057] See also Figure 6 In some embodiments, the first wall 27, the third side wall 26 and the second wall 28 are stepped.

[0058] In this way, the first wall 27 , the third side wall 26 and the second wall 28 are stepped, which can reduce the contact area between the bottom wall 23 and the fan assembly 10 , and reduce the influence of the bottom wall 23 on the air intake of the fan assembly 10 .

[0059] Specifically, the angle formed by the third side wall 26 and the first wall 27 and the second wall 28 can be a right angle, an acute angle or an obtuse angle. The fan assembly 10 can contact the first wall 27 or the second wall 28. When the first wall 27 contacts the fan assembly 10, the area of ​​the first side wall 24 can be the sum of the areas of the second side wall 25 and the third side wall 26, or it can be greater than the sum of the areas of the second side wall 25 and the third side wall 26; when the second wall 28 contacts the fan assembly 10, the area of ​​the second side wall 25 can be the sum of the areas of the first side wall 24 and the third side wall 26, or it can be greater than the sum of the areas of the first side wall 24 and the third side wall 26. The smaller the area of ​​the first wall 27 and the second wall 28 in contact with the fan assembly 10, the smaller the impact on the air intake of the fan assembly 10, and the higher the efficiency of the fan assembly 10 in sucking oil smoke.

[0060] See also Figure 3 In some embodiments, the fan assembly 10 is formed with a cavity 13 communicating with the air outlet 12 , and the water guide 20 is partially disposed in the cavity 13 .

[0061] In this way, the cavity 13 is used to accommodate the water guide 20, and the airflow flows in the cavity 13, so as to make the oil smoke flow from the air inlet 11 through the cavity 13 to the air outlet 12, so as to be discharged outdoors.

[0062] Specifically, the cavity 13 may be a cavity formed by the shell of the fan assembly 10, the cavity 13 is connected to the air inlet 11 and the air outlet 12, and the water guide 20 is arranged at the connection between the cavity 13 and the air inlet 11. The cavity 13 can accommodate electrical components inside the fan assembly 10, such as a fan, and the fan may be an axial flow fan, which includes a motor and fan blades. When the motor is working, it drives the fan blades to rotate, sucking oil smoke from the air inlet 11 and discharging it from the air outlet 12. By controlling the speed of the motor, the rate at which the oil fume purification device 100 purifies oil smoke can be controlled.

The oil smoke purification device 100 may filter and condense the oil smoke, collect the filtered impurities in the filter assembly 30, collect the condensed water in the water collection box 40, and discharge the filtered oil smoke outdoors, thereby reducing the impact of the oil smoke on the kitchen environment.

[0076] See also Figure 1 and Figure 3 In some embodiments, the cooking appliance 200 includes a housing assembly 210 , the housing assembly 210 is connected to the fan assembly 10 , the housing assembly 210 is formed with a mounting groove 211 communicating with the air inlet 11 , and the water guide 20 is at least partially disposed in the mounting groove 211 .

[0077] In this way, the housing assembly 210 can isolate the charged body inside the cooking appliance 200 from the external environment, thereby preventing the external environment from affecting the operation of the charged body and preventing the charged body from causing electric shock injuries to the user.

[0078] Specifically, the housing assembly 210 can be connected to the fan assembly 10 by means of threads, and the mounting groove 211 penetrates the housing assembly 210 along the height direction of the housing assembly 210. The shape and size of the mounting groove 211 are adapted to the water guide member 20, so that the water guide member 20 can be at least partially disposed in the mounting groove 211. For example, the mounting groove 211 and the water guide member 20 are both rectangular in shape and have the same size. The water guide member 20 can be completely disposed in the mounting groove 211, or partially disposed in the mounting groove 211. The portion disposed in the mounting groove 211 can be the upper end, the lower end, or the middle of the water guide member 20 disposed in the mounting groove 211.

[0079] In one embodiment, an electromagnetic component is disposed in the shell component 210, and the electromagnetic component includes a heating device and a control device. The heating device includes a plurality of heating plates, and the plurality of heating plates are distributed on both sides of the mounting groove 211. The heating plates can generate heat after being energized to achieve the purpose of heating. The control device is a circuit board integrating multiple electronic components. The control device is connected to the heating device and can adjust and control the heating device.

[0080] See also Figure 1 In some embodiments, the cooking appliance 200 further includes a panel 220 , which is disposed on the housing assembly 210 and has an opening 221 aligned with the mounting groove 211 , and the opening 221 faces upward.

[0081] In this way, the panel 220 can play a bearing role to support the heated container. The opening 221 of the panel 220 faces upward, so that the oil smoke generated at the upper end of the panel 220 can enter the oil smoke purification device 100 through the opening 221.

[0082] Specifically, the panel 220 may be an operation panel 220 of an induction cooker, which is usually made of glass or metal. The panel 220 is provided with buttons and a display screen, which can select and display the working mode of the induction cooker. The opening 221 penetrates the panel 220 along the thickness direction of the panel 220, and the shape and size of the opening 221 can be adapted to the installation groove 211, so that the water guide 20 can be installed in the installation groove 211 through the opening 221.

[0083] See also Figure 1 and Figure 2 In some embodiments, the household appliance 1000 includes a grille element 300 , which is detachably mounted on a surface of the filter assembly 30 and covers the mounting groove 211 .

[0084] In this way, the grille element 300 can form the appearance of the household appliance 1000. The detachable grille element 300 is easy to operate and is convenient for cleaning and maintenance. At the same time, the grille element 300 can play a role in preliminary condensation of oil smoke, so that part of the grease contained in the oil smoke adheres to the grille element 300, preventing the grease from being discharged from the oil smoke purification device 100.

[0085] Specifically, the grille element 300 may include a bracket 310 and a plurality of partitions 320 disposed on the bracket 310. The partitions 320 are arranged at intervals along the length direction of the grille element 300. The partitions 320 and the bracket 310 together form a guide channel. The oil smoke enters the fan assembly 10 from the guide channel along with the airflow. The plurality of partitions 320 can divide the oil smoke into multiple strands, thereby improving the dispersion of the oil smoke, thereby increasing the amount of oil smoke inhaled by the oil fume purification device 100, and further improving the purification efficiency of the oil fume.
