[0032] Please combine Figure 1 , Figure 2 as well as Figure 3As shown, the present application first provides a heat dissipation and exhaust structure, including an inner tank 10, a flue 20, an air duct 30 and an adjusting component 40, wherein a fan 36 is arranged in the air duct 30, and the air duct 30 has an air inlet 30a, a steam inlet 30b, a first outlet 30c and a second outlet 30d, wherein the steam inlet 30b and the second outlet 30d are both connected to the inner tank 10, the air inlet 30a is connected to the outside of the air duct 30, the first outlet 30c is connected to the flue 20, and the adjusting component 40 is used to block or open the first outlet 30c.

[0033] In the present application, by opening two inlets on the air duct 30, the fan 36 can generate negative pressure in the air duct 30 after being started, so that the external cold air and the steam inside the inner pot 10 are sucked into the air duct 30 through the steam inlet 30a and the steam inlet 30b respectively. Only one fan 36 is required to complete the heat dissipation of the components around the air duct 30 and the dehumidification of the inner pot 10; in addition, two outlets are also opened on the air duct 30, and together with the adjustment component 40 that can block or open the first outlet 30c, steam forced exhaust or steam reflux can be selected according to actual needs to meet different cooking needs and improve the versatility of the equipment.

[0034] Specifically, when forced steam exhaust is required, the regulating component 40 opens the first outlet 30c. Since the entire flue 20 is in a strong negative pressure state when the range hood is working, most of the cold air and steam entering the air duct 30 will flow directly into the flue 20 under the strong negative pressure in the flue 20, thereby achieving rapid steam exhaust;

[0035] When steam reflux is required, the regulating component 40 blocks the first outlet 30c. At this time, the cold air and steam entering the air duct 30 enter the inner tank 10 through the second outlet 30d under the action of the fan 36, realizing the internal circulation of steam and increasing the endurance of the steaming function.

[0036] In some embodiments, a vent valve is provided between the second outlet 30d and the inner pot 10. In the steam forced exhaust mode, closing the vent valve can completely prevent the steam in the air duct 30 from flowing back into the inner pot 10 through the second outlet 30d.

[0037] Please combine Figure 1 , Figure 3 as well as Figure 4As shown, in some embodiments, the air duct 30 includes a mounting plate 31, an air guide plate 32 and a fan fixing seat 33 fixed in sequence, a first chamber 34 is formed between the mounting plate 31 and the air guide plate 32; a second chamber 35 is formed between the air guide plate 32 and the fan fixing seat 33, the air inlet 30a and the steam inlet 30b are both connected to the second chamber 35, and the first outlet 30c and the second outlet 30d are both connected to the first chamber 34; the fan 36 is fixed to the fan fixing seat 33 and is located in the first chamber 34, and the air guide plate 32 is provided with a through hole 321 connecting the first chamber 34 and the second chamber 35.

[0038] In the steam forced exhaust mode, the heat dissipation path is: external cold air → components to be cooled around the air duct 30 → air inlet 30a → first chamber 34 → through hole 321 → fan 36 → second chamber 35 → first outlet 30c → flue 20, and the steam dehumidification path is: liner 10 → steam inlet 30b → first chamber 34 → through hole 321 → fan 36 → second chamber 35 → first outlet 30c → flue 20;

[0039] In the steam reflux mode, the heat dissipation path is: external cold air → components to be cooled around the air duct 30 → air inlet 30a → first chamber 34 → through hole 321 → fan 36 → second chamber 35 → second outlet 30d → liner 10, and the steam dehumidification path is: liner 10 → steam inlet 30b → first chamber 34 → through hole 321 → fan 36 → second chamber 35 → second outlet 30d → liner 10.

[0040] Please combine Figure 1 as well as Figure 3 As shown, in some embodiments, the first chamber 34 includes a volute cavity 341 and an air outlet passage 342, the fan 36 is located in the volute cavity 341, the air outlet passage 342 extends in a radial direction, one end is connected to the volute cavity 341, and the other end is connected to the first outlet 30c, the second outlet 30d is connected to the air outlet passage 342, and the axial direction of the second outlet 30d is perpendicular to the air outlet passage 342.

[0041] With such arrangement, in the steam forced exhaust mode, most of the cold air and steam can enter the flue 20 along the air outlet passage 342, thereby avoiding as much as possible the steam from flowing back to the inner tank 10 through the second outlet 30d in the steam forced exhaust mode.

[0042] Please combine Figure 1 as well as Figure 3 As shown, in some embodiments, the adjustment component 40 includes a motor 41 and a push plate 42. The motor 41 is fixed relative to the air duct 30, and the push plate 42 is fixed to the movable end of the motor 41. The push plate 42 passes through the air duct 30 and is located between the first outlet 30c and the second outlet 30d. The motor 41 is used to drive the push plate 42 to move to block or open the air outlet passage 342.

[0043] Specifically, the motor 41 can block or open the air outlet passage 342 by driving the push plate 42 to extend and / or rotate. Of course, in some other embodiments, the adjustment component 40 can also adopt other common structures, which are not further limited in this application.

[0044] Please combine Figure 3 as well as Figure 4 As shown, in some embodiments, the air guide plate 32 is provided with a plurality of air inlets 30a along the circumferential direction of the fan 36 to enhance the air intake effect of the air duct 30, accelerate the air flow inside the equipment, and meet the heat dissipation requirements of components at different positions.

[0045] In some embodiments, one of the air inlets 30a is directly opposite to the opening of the device door body, so that when the fan 36 is working, it can absorb the hot air inside the door body through the air inlet 30a, thereby cooling the door body and avoiding burns caused by the high temperature of the door body when the user opens the door.

[0046] In some embodiments, an air inlet 30a is also provided on the top of the fan fixing base 33, and the air inlet 30a is facing the power board mounting box of the equipment, so that when the fan 36 is working, it can absorb the hot air around the power board through the air inlet 30a, thereby dissipating the heat of the power board. There is no need to set up an independent heat dissipation structure for the power board, thereby reducing the overall cost of the equipment.

[0047] Please combine Figure 3 as well as Figure 5 As shown, in some embodiments, a reflux hole 311 a is opened at the bottom of the mounting plate 31 , and the reflux hole 311 a is connected to the inner tank 10 and / or the oil cup 50 through a pipeline.

[0048] When steam and cold air meet in the air duct 30, part of the steam will condense to form condensed water. By opening a reflux hole 311a at the bottom of the mounting plate 31, this part of the condensed water can be refluxed for utilization. When the condensed water flows back into the inner tank 10, the endurance of the steaming function can be further improved, and special needs such as humidification baking can be met. When the condensed water flows back into the oil cup 50, the oil cup 50 can be preliminarily cleaned to prevent the accumulation of oil stains in the oil cup 50, which is convenient for subsequent cleaning of the oil cup 50.

[0049] In some embodiments, the air guide plate 32 is provided with a condensation hole 322 connecting the first chamber 34 and the second chamber 35. The condensation hole 322 is located between the fan 36 and the air outlet passage 342, so that the condensation water formed by the steam and the cold air in the second chamber 35 can flow into the first chamber 34 through the condensation hole 322, and finally flow back to the inner tank 10 and / or the oil cup 50 along the reflux hole 311a.

[0050] Please combine Figure 1 as well as Figure 5 As shown, in some embodiments, the pipeline includes a main return pipe 61 and two branch return pipes 62, one end of the main return pipe 61 is connected to the return hole 311a, and the other end is respectively connected to the two branch return pipes 62, one of which is connected to the inner tank 10, and the other is connected to the oil cup 50.

[0051] Specifically, one of the branch return pipes 62 is connected to the inner tank 10 near the bottom surface to guide the condensed water to the bottom of the inner tank 10 to prevent the condensed water from affecting the normal operation of the equipment.

[0052] Of course, in some other embodiments, according to actual requirements of the equipment, the reflux hole 311a may also be connected only to the inner tank 10 or only to the oil cup 50.

[0053] Please combine Figure 1 as well as Figure 5 As shown, in some embodiments, the pipeline also includes a three-way valve 63, and the main return pipe 61 is connected to the two branch return pipes 62 through the three-way valve 63; the three-way valve 63 can connect the main return pipe 61 with any branch return pipe 62 according to actual needs, so as to further improve the versatility of the heat dissipation and exhaust structure of the present application.

[0054] Please combine Figure 3 as well as Figure 5 As shown, in some embodiments, a sunken water storage tank 311 is provided at the bottom of the mounting plate 31 , and a reflux hole 311 a is opened at the bottom of the water storage tank 311 .

[0055] A second aspect of the present application provides a multifunctional cooking device, comprising the above-mentioned heat dissipation and steam exhaust structure.

[0056] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0057] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent.
