Description

Technical Field

[0001] The utility model relates to the technical field of cooking equipment, and more specifically, to a smoke machine assembly and an integrated stove. Background Art

[0002] A smoke stove integrated machine is a kitchen appliance that integrates a stove and a range hood. Generally, the smoke stove integrated machine includes a volute, a wind wheel, and a motor, and the motor drives the rotating wind wheel to suck oil fumes.

[0003] In the related art, a structure for filtering water vapor is provided in the smoke stove integrated machine to reduce the probability of liquid contacting the motor.

[0004] However, when a large amount of liquid accidentally enters the smoke stove integrated machine, the structure for filtering water vapor cannot process the short-time large amount of liquid poured in a timely manner, resulting in the liquid entering the motor, causing problems such as motor short circuit and electric leakage, and leading to the technical problems that the motor of the smoke stove integrated machine is easily damaged by liquid and the product safety and reliability are poor. Summary of the Utility Model

[0005] The utility model aims to solve at least one of the technical problems existing in the prior art.

[0006] To this end, a first aspect of the utility model provides a smoke machine assembly.

[0007] A second aspect of the utility model provides an integrated stove.

[0008] In view of this, a first aspect of the utility model provides a smoke machine assembly, which includes: a housing, the housing includes a cavity; a motor, the motor is arranged in the housing; a wind wheel, the wind wheel is connected to the motor, the motor is used to drive the wind wheel to rotate, the wind wheel includes a first guiding surface, the first guiding surface surrounds the motor, and the first guiding surface is used to guide the liquid to flow away from the motor.

[0009] This application provides a smoke machine assembly, which belongs to the power structure on an integrated stove. Specifically, the smoke machine assembly can suck oil fumes and discharge the sucked oil fumes to a designated area through a flue.

[0010] The smoke machine assembly includes a housing, a motor, and a wind wheel. The housing is the main frame structure of the smoke machine assembly, and is used to position and support other working structures on the smoke machine assembly. A cavity is formed inside the housing, and an air inlet and an air outlet communicating the cavity with the external space of the housing are provided on the housing. The motor is installed in the cavity, and the power output end of the motor is connected to the wind wheel. The motor is used to drive the wind wheel to rotate, so as to suck the oil fumes into the housing through the air inlet by the wind wheel, and discharge the oil fumes out of the housing through the air outlet after pressurization and acceleration, thereby realizing the suction and centralized discharge of the oil fumes.

[0011] On this basis, a first guiding surface is provided on the wind wheel. The first guiding surface is sleeved around the motor. The first guiding surface faces away from the motor and is inclined from the circumferential side of the motor towards the lower edge of the wind wheel. The first guiding surface can form a barrier around the motor to prevent liquid from directly dripping onto the motor. After the liquid contacts the first guiding surface, under the action of the gravity of the liquid, the first guiding surface can guide the liquid away from the motor. Specifically, the liquid can be guided to the edge of the wind wheel, and the centrifugal force generated by the rotation of the wind wheel can throw the liquid away from the motor.

[0012] It can be seen that by providing the first guiding surface on the wind wheel, it is possible to effectively prevent the liquid entering the interior of the housing from contacting the motor. Even if a large amount of liquid accidentally pours into the integrated range hood, the liquid can be guided to an area away from the motor through the guiding action of the first guiding surface, avoiding the short circuit or electric leakage of the motor due to contact with the liquid. Thus, the technical problems of the motor being easily damaged by liquid and the poor safety and reliability of the product in the related art are solved, and furthermore, the technical effects of improving the waterproof ability of the smoke machine assembly, reducing the failure rate of the motor, and improving the safety and reliability of the smoke machine assembly are achieved.

[0013] In addition, the above-mentioned smoke machine assembly provided by the present utility model may further have the following additional technical features:

[0014] In some technical solutions of the present utility model, optionally, the housing includes an inlet and an outlet; the inlet is located above the motor, and the outlet is located on the circumferential side of the motor; the wind wheel is located between the inlet and the motor.

[0015] In this technical solution, the housing is a volute casing, and the housing is formed by splicing an upper volute casing and a lower volute casing.

[0016] Among them, the axial direction of the volute casing corresponds to the height direction of the smoke machine assembly. An inlet is provided at the top of the volute casing, and an outlet is provided corresponding to the circumferential side of the volute casing. The motor and the wind wheel are arranged below the inlet. The motor is connected to the bottom wall of the volute casing. The wind wheel is installed between the inlet and the motor. After the motor drives the wind wheel to rotate, the wind wheel can suck the oil fume from the inlet from top to bottom into the interior of the wind wheel, and then the rotating wind wheel throws the oil fume towards the side wall of the volute casing. Finally, the side wall of the volute casing accelerates the oil fume, so that the oil fume can be quickly discharged from the outlet, thereby achieving the technical effect of improving the oil fume suction efficiency of the smoke machine assembly.

[0017] In some technical solutions of the present utility model, optionally, the wind wheel includes a through hole, and the motor is inserted through the through hole; the first guiding surface surrounds the through hole, and in the radial direction of the wind wheel, the height of the first guiding surface gradually decreases.

[0018] In this technical solution, through holes are provided on the wind wheel, and the through holes penetrate the wind wheel along the axial direction of the wind wheel. During the assembly process, the wind wheel is sleeved outside the motor through the through holes. By setting the through holes, the wind wheel and the motor can partially overlap in the height direction, thereby reducing the height of the combined motor and wind wheel and providing convenient conditions for the ultra-thin design of the range hood assembly.

[0019] On this basis, the first guiding surface surrounds the periphery of the through hole. In the radial direction of the wind wheel from the inside to the outside, the height of the first guiding surface gradually decreases, thus forming an inclined surface that slopes downward from top to bottom in the direction away from the motor. After the liquid drops on the first guiding surface, the liquid will flow to the surrounding areas with lower height under the action of gravity, so that the liquid gradually moves away from the motor, preventing this part of the liquid from directly flowing into the motor, thereby solving the technical problems in the related art that the motor is easily damaged by the liquid and the product has poor safety and reliability, and further achieving the technical effects of improving the waterproof ability of the range hood assembly, reducing the failure rate of the motor, and improving the safety and reliability of the range hood assembly.

[0020] In some technical solutions of the present invention, optionally, the range hood assembly further includes: a first rib, the first rib is connected to one end of the first guiding surface close to the inlet, and the first rib surrounds the through hole.

[0021] In this technical solution, a first rib is provided at the top end of the first guiding surface, and the first rib surrounds the periphery of the through hole and the motor. After the assembly is completed, the first guiding surface fits with the peripheral side surface of the motor.

[0022] By setting the first rib, a shield can be formed in the area on the peripheral side of the motor that is not covered by the first guiding surface. When a large amount of liquid that accidentally enters the integrated stove enters the cavity, the liquid flowing in from the inlet will be blocked by the first rib to prevent the liquid from directly dripping into the interior of the motor. This part of the liquid is received by the first guiding surface after being blocked and is finally guided to an area away from the motor by the first guiding surface.

[0023] It can be seen that by setting the first rib, the probability of the liquid contacting the motor can be further reduced in cooperation with the first guiding surface, and further achieve the technical effects of improving the waterproof ability of the range hood assembly, reducing the failure rate of the motor, and improving the safety and reliability of the range hood assembly.

[0024] In some technical solutions of the present invention, optionally, the range hood assembly further includes: a second rib, the second rib is provided on the bottom wall of the housing, the second rib is located below the wind wheel, and the second rib surrounds the motor.

[0025] In this technical solution, the range hood assembly further includes a second rib. The second rib is disposed on the bottom wall of the housing, on the circumferential side of the motor, and below the impeller. The second rib is annular and is disposed around the motor. The second rib is used to prevent the liquid flowing along the bottom wall of the housing from contacting the motor. Specifically, after the liquid contacts the second rib, it is blocked by the second rib to prevent the liquid from continuing to flow towards the motor, thereby avoiding the liquid thrown towards the periphery of the motor by the impeller from entering the motor along the inner surface of the housing, and further achieving the technical effects of improving the waterproof ability of the range hood assembly, reducing the failure rate of the motor, and enhancing the safety and reliability of the range hood assembly.

[0026] Among them, the second rib is integrally formed on the housing, and specifically, an injection molding process can be adopted. By providing an integrated housing and second rib, on the one hand, the process complexity of the range hood assembly can be reduced, which is beneficial to reducing the production cost of the range hood assembly. On the other hand, there are no structural gaps between the integrated second rib and the housing, which can prevent the liquid from flowing into the motor through the structural gaps.

[0027] In some technical solutions of the present utility model, optionally, the number of the second ribs is multiple, and the multiple second ribs are spaced apart in the radial direction of the impeller.

[0028] In this technical solution, a plurality of second ribs are disposed on the bottom wall of the housing, and the plurality of second ribs are nested on the circumferential side of the motor, that is, the plurality of second ribs are spaced apart in the radial direction of the motor and the impeller.

[0029] When the liquid accumulates excessively and crosses the outer second rib, the inner second rib can form a second barrier, enabling the liquid to continue to accumulate between the two second ribs. When the number of the second ribs is greater than two, the inner second rib can further form a third and fourth barrier, which will not be elaborated here.

[0030] It can be seen that by providing a plurality of second ribs, multiple layers of protection can be formed outside the motor, thereby further reducing the probability of the liquid contacting the motor, and further achieving the technical effects of improving the waterproof ability of the range hood assembly, reducing the failure rate of the motor, and enhancing the safety and reliability of the range hood assembly.

[0031] In some technical solutions of the present utility model, optionally, the height of the second rib ranges from: greater than or equal to 5 mm and less than or equal to 10 mm.

[0032] In this technical solution, the height of the second rib needs to be greater than or equal to 5 mm and less than or equal to 10 mm.

[0033] By defining the height of the second rib to be greater than or equal to 5 mm, the blocking effect of the second rib on the liquid can be ensured, increasing the difficulty for the liquid to cross the second rib, thereby enhancing the protection effect of the second rib on the motor.

[0034] By limiting the height of the second rib to be less than or equal to 10 mm, on the one hand, the probability of interference between the second rib and the wind wheel can be reduced, and on the other hand, the height of the wind wheel can be reduced, thereby providing convenient conditions for the ultra-thin design of the range hood assembly.

[0035] In some technical solutions of the present utility model, optionally, the bottom wall of the housing includes a second flow guiding surface, and the second flow guiding surface is located outside the second rib; the second flow guiding surface slopes downward in the direction from the second rib to the outlet.

[0036] In this technical solution, the bottom wall of the housing is further provided with a second flow guiding surface, and the second flow guiding surface is located outside the second rib. When the number of the second ribs is multiple, the second flow guiding surface is located outside the outermost second rib.

[0037] Among them, the second flow guiding surface slopes downward in the direction from the second rib to the outlet, that is, the height of the second flow guiding surface gradually decreases in the direction close to the outlet. By providing the inclined second flow guiding surface, the liquid outside the second rib can flow to the outlet by gravity and is finally discharged out of the housing through the outlet, avoiding the accumulation of liquid inside the housing and preventing the excessively accumulated liquid from crossing the second rib. Thereby, the technical effects of improving the drainage rate of the housing, reducing the probability of the motor being damaged by the liquid, further improving the waterproof ability of the range hood assembly, reducing the failure rate of the motor, and improving the safety and reliability of the range hood assembly are achieved.

[0038] In some technical solutions of the present utility model, optionally, the inclination angle of the second flow guiding surface ranges from: greater than or equal to 1°, and less than or equal to 6°.

[0039] In this technical solution, the inclination angle of the second flow guiding surface needs to be greater than or equal to 1°, and less than or equal to 6°.

[0040] By limiting the inclination angle of the second flow guiding surface to be greater than or equal to 1°, it can be ensured that the liquid can converge towards the outlet and avoid the accumulation of liquid in the housing. By limiting the inclination angle of the second flow guiding surface to be less than or equal to 6°, the thickness of the housing can be reduced on the basis of meeting the requirement of the liquid discharging by itself, thereby providing convenient conditions for the ultra-thin design of the range hood assembly and making the integrated stove equipped with this range hood assembly suitable for small-sized cabinets.

[0041] Specifically, the inclination angle of the second flow guiding surface can be selected as 2°, 4° or 5° for draining water without excessively increasing the thickness of the range hood assembly.

[0042] The second aspect of the present utility model provides an integrated stove, which includes: a main body, the main body includes a smoke inlet and a smoke outlet, the main body includes a flue and a drainage channel, the flue communicates with the smoke inlet and the smoke outlet, and the drainage channel communicates with the flue and the outside of the main body; a smoke machine assembly as in any of the above technical solutions, the housing is connected to the main body, and the cavity communicates with the smoke outlet; a grease separation assembly, the grease separation assembly is arranged in the flue, and the grease separation assembly is used to separate the grease in the oil fume.

[0043] In this technical solution, an integrated stove provided with the smoke machine assembly in any of the above technical solutions is defined. Therefore, this integrated stove has the advantages of the smoke machine assembly in any of the above technical solutions, and can achieve the technical effects that the smoke machine assembly in any of the above technical solutions can achieve. To avoid repetition, it will not be elaborated here.

[0044] On this basis, the integrated stove includes a main body and a grease separation assembly.

[0045] The main body is the main frame structure of the integrated stove. The top of the main body forms the cooking surface of the integrated stove, and cooking utensils are heated on the cooking surface. A smoke inlet is opened on the cooking surface. A flue is formed inside the main body, and a smoke outlet is also opened at the bottom of the main body. The first end of the flue communicates with the smoke inlet, and the second end of the flue communicates with the smoke outlet. The integrated stove sucks the external oil fume through the smoke inlet. After the oil fume enters the flue, it is filtered in the flue, and the filtered oil fume is discharged from the flue through the smoke outlet.

[0046] The grease separation assembly is arranged in the flue, and the grease separation assembly is arranged opposite to the smoke inlet on the flue. After the oil fume flows into the smoke inlet, it needs to flow through the grease separation assembly first. The grease separation assembly can separate the grease and water vapor mixed in the oil fume, complete the pre - oil - water separation of the oil fume, avoid the oil fume carrying oil and water into the smoke machine assembly. Thus, on the one hand, it protects the smoke machine assembly from being polluted by oil and water, prolongs the service life of the integrated stove; on the other hand, it avoids the oil and water accumulated in the flue from generating peculiar smells; on the third hand, it avoids the oil fume treated by the integrated stove from causing secondary pollution to the environment.

[0047] Wherein, a drainage channel is also arranged in the main body, and the drainage channel can discharge the liquid separated by the grease separation assembly to the outside of the main body, thereby avoiding excessive accumulation of the liquid in the main body.

It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments may be combined with each other.

[0059] In the following description, many specific details are set forth in order to fully understand the present utility model. However, the present utility model may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present utility model is not limited by the specific embodiments disclosed below.

[0060] Next, refer to Figures 1 to 6 to describe the range hood assembly and the integrated range hood according to some embodiments of the present utility model.

[0061] As Figure 1 , Figure 2 , Figure 3 and Figure 4As shown in the figure, an embodiment of the present utility model provides a smoke machine assembly 100, which includes: a housing 110, the housing 110 includes a cavity 1102; a motor 120, the motor 120 is arranged inside the housing 110; a wind wheel 130, the wind wheel 130 is connected to the motor 120, the motor 120 is used to drive the wind wheel 130 to rotate, the wind wheel 130 includes a first guiding surface 1302, the first guiding surface 1302 surrounds the motor 120, and the first guiding surface 1302 is used to guide the liquid to flow away from the motor 120.

[0062] Figure 2 In the figure, arrow a indicates the flow direction of the liquid.

[0063] This application provides a smoke machine assembly 100, which belongs to the power structure on the integrated stove 200. Specifically, the smoke machine assembly 100 can suck oil fume and discharge the sucked oil fume to a designated area through the flue 2106.

[0064] The smoke machine assembly 100 includes a housing 110, a motor 120 and a wind wheel 130. The housing 110 is the main frame structure of the smoke machine assembly 100, and is used to position and support other working structures on the smoke machine assembly 100. A cavity 1102 is formed inside the housing 110, and an air inlet 2102 and an exhaust port 2104 that communicate the cavity 1102 with the external space of the housing 110 are provided on the housing 110. The motor 120 is installed in the cavity 1102, and the power output end of the motor 120 is connected to the wind wheel 130. The motor 120 is used to drive the wind wheel 130 to rotate, so as to suck the oil fume into the housing 110 through the wind wheel 130 from the air inlet 2102, and discharge the oil fume from the exhaust port 2104 after pressurization and acceleration, thereby realizing the suction and centralized discharge of the oil fume.

[0065] On this basis, a first guiding surface 1302 is provided on the wind wheel 130. The first guiding surface 1302 is sleeved around the motor 120. The first guiding surface 1302 faces away from the motor 120 and the first guiding surface 1302 is inclined from the peripheral side of the motor 120 towards the lower edge of the wind wheel 130. The first guiding surface 1302 can form a barrier around the motor 120 to prevent the liquid from directly dropping on the motor 120. After the liquid contacts the first guiding surface 1302, under the action of the gravity of the liquid, the first guiding surface 1302 can guide the liquid away from the motor 120. Specifically, the liquid can be guided to the edge of the wind wheel 130, and the liquid can be thrown away from the motor 120 by the centrifugal force generated by the rotation of the wind wheel 130.

[0066] It can be seen that by providing the first guiding surface 1302 on the wind wheel 130, the liquid entering the interior of the housing 110 can be effectively prevented from contacting the motor 120. Even if a large amount of liquid accidentally pours into the interior of the integrated range hood 200, the liquid can be guided to an area far from the motor 120 through the guiding action of the first guiding surface 1302, avoiding short - circuit or electric leakage of the motor 120 due to contact with the liquid. Thus, the technical problem in the related art that the motor 120 is easily damaged by liquid and the product has poor safety and reliability is solved, and further, the technical effects of improving the waterproof ability of the smoke machine assembly 100, reducing the failure rate of the motor 120, and enhancing the safety and reliability of the smoke machine assembly 100 are achieved.

[0067] As Figure 1 and Figure 2 shown, in some embodiments of the present utility model, optionally, the housing 110 includes an inlet 1104 and an outlet 1106; the inlet 1104 is located above the motor 120, and the outlet 1106 is located on the periphery of the motor 120; the wind wheel 130 is located between the inlet 1104 and the motor 120.

[0068] In this embodiment, the housing 110 is a volute, and the housing 110 is formed by splicing an upper volute and a lower volute.

[0069] Wherein, the axial direction of the volute corresponds to the height direction of the smoke machine assembly 100. An inlet 1104 is provided at the top of the volute, and an outlet 1106 is provided on the periphery of the volute corresponding to it. The motor 120 and the wind wheel 130 are arranged below the inlet 1104. The motor 120 is connected to the bottom wall of the volute. The wind wheel 130 is installed between the inlet 1104 and the motor 120. After the motor 120 drives the wind wheel 130 to rotate, the wind wheel 130 can suck the cooking fume from the inlet 1104 from top to bottom into the interior of the wind wheel 130, and then the rotating wind wheel 130 throws the cooking fume towards the side wall of the volute. Finally, the side wall of the volute accelerates the cooking fume, enabling the cooking fume to be quickly discharged from the outlet 1106, thus achieving the technical effect of improving the cooking fume suction efficiency of the smoke machine assembly 100.

[0070] As Figure 1 , Figure 2 , Figure 3 and Figure 4 shown, in some embodiments of the present utility model, optionally, the wind wheel 130 includes a through - hole 1304, and the motor 120 passes through the through - hole 1304; the first guiding surface 1302 surrounds the through - hole 1304, and in the radial direction of the wind wheel 130, the height of the first guiding surface 1302 gradually decreases.

[0071] In this embodiment, a through hole 1304 is provided on the wind wheel 130. The through hole 1304 penetrates the wind wheel 130 along the axial direction of the wind wheel 130. During the assembly process, the wind wheel 130 is sleeved outside the motor 120 through the through hole 1304. By providing the through hole 1304, the wind wheel 130 and the motor 120 can partially overlap in the height direction, thereby reducing the height of the combined motor 120 and wind wheel 130 and providing convenient conditions for the ultra-thin design of the range hood assembly 100.

[0072] On this basis, the first guiding surface 1302 surrounds the periphery of the through hole 1304. In the radial direction of the wind wheel 130 from the inside to the outside, the height of the first guiding surface 1302 gradually decreases, thereby forming an inclined surface that slopes downward from top to bottom in the direction away from the motor 120. After the liquid drops on the first guiding surface 1302, the liquid will flow to the surrounding areas with lower height under the action of gravity, so that the liquid gradually moves away from the motor 120, preventing this part of the liquid from directly flowing into the motor 120, thus solving the technical problems in the related art that the motor 120 is easily damaged by the liquid and the product has poor safety and reliability. Furthermore, the technical effects of improving the waterproof ability of the range hood assembly 100, reducing the failure rate of the motor 120, and improving the safety and reliability of the range hood assembly 100 are achieved.

[0073] As Figure 2 and Figure 3 shown, in some embodiments of the present utility model, optionally, the range hood assembly 100 further includes: a first rib 132. The first rib 132 is connected to one end of the first guiding surface 1302 close to the inlet 1104, and the first rib 132 surrounds the through hole 1304.

[0074] In this embodiment, a first rib 132 is provided at the top end of the first guiding surface 1302. The first rib 132 surrounds the periphery of the through hole 1304 and the motor 120. After the assembly is completed, the first guiding surface 1302 is attached to the peripheral side surface of the motor 120.

[0075] By providing the first rib 132, a shield can be formed in the area on the peripheral side of the motor 120 that is not covered by the first guiding surface 1302. When a large amount of liquid that accidentally enters the integrated stove 200 enters the cavity 1102, the liquid flowing in from the inlet 1104 will be blocked by the first rib 132 to prevent the liquid from directly dripping into the interior of the motor 120. This part of the liquid is received by the first guiding surface 1302 after being blocked and is finally guided to an area away from the motor 120 by the first guiding surface 1302.

[0076] It can be seen that by providing the first rib 132, the probability of liquid contacting the motor 120 can be further reduced in cooperation with the first flow guiding surface 1302, thereby achieving the technical effects of improving the waterproof ability of the range hood assembly 100, reducing the failure rate of the motor 120, and enhancing the safety and reliability of the range hood assembly 100.

[0077] As Figure 1 , Figure 2 and Figure 5 shown, in some embodiments of the present invention, optionally, the range hood assembly 100 further includes: a second rib 140, the second rib 140 is provided on the bottom wall of the housing 110, the second rib 140 is located below the impeller 130, and the second rib 140 surrounds the motor 120.

[0078] In this embodiment, the range hood assembly 100 further includes a second rib 140, the second rib 140 is disposed on the bottom wall of the housing 110, the second rib 140 is located on the circumferential side of the motor 120 and below the impeller 130. The second rib 140 is annular, and the second rib 140 is disposed around the motor 120. Wherein, the second rib 140 is used to prevent the liquid flowing along the bottom wall of the housing 110 from contacting the motor 120. Specifically, after the liquid contacts the second rib 140, it is blocked by the second rib 140 to prevent the liquid from continuing to flow towards the motor 120, so as to avoid the liquid thrown towards the periphery of the motor 120 by the impeller 130 from entering the motor 120 along the inner surface of the housing 110, thereby achieving the technical effects of improving the waterproof ability of the range hood assembly 100, reducing the failure rate of the motor 120, and enhancing the safety and reliability of the range hood assembly 100.

[0079] Wherein, the second rib 140 is integrally formed on the housing 110, and specifically, an injection molding process can be adopted. By providing the integral housing 110 and the second rib 140, on the one hand, the process complexity of the range hood assembly 100 can be reduced, which is beneficial to reducing the production cost of the range hood assembly 100. On the other hand, there is no structural gap between the integral second rib 140 and the housing 110, which can prevent the liquid from flowing into the motor 120 through the structural gap.

[0080] As Figure 5 shown, in some embodiments of the present invention, optionally, the number of the second ribs 140 is multiple, and the multiple second ribs 140 are spaced apart in the radial direction of the impeller 130.

[0081] In this embodiment, a plurality of second ribs 140 are provided on the bottom wall of the housing 110, and the plurality of second ribs 140 are nested on the circumferential side of the motor 120, that is, the plurality of second ribs 140 are spaced apart along the radial direction of the motor 120 and the impeller 130.

[0082] When the liquid accumulates excessively and crosses the second rib 140 on the outer side, the second rib 140 on the inner side can form a second barrier, enabling the liquid to continue to accumulate between these two second ribs 140. When the number of the second ribs 140 is greater than two, the second rib 140 on the inner side can further form a third and a fourth barrier, which will not be elaborated here.

[0083] It can be seen that by providing a plurality of second ribs 140, multiple layers of protection can be formed on the outer side of the motor 120, thereby further reducing the probability of the liquid contacting the motor 120, and then achieving the technical effects of enhancing the waterproof ability of the range hood assembly 100, reducing the failure rate of the motor 120, and enhancing the safety and reliability of the range hood assembly 100.

[0084] In some embodiments of the present invention, optionally, the height of the second rib 140 ranges from greater than or equal to 5 mm to less than or equal to 10 mm.

[0085] In this embodiment, the height of the second rib 140 needs to be greater than or equal to 5 mm and less than or equal to 10 mm.

[0086] By defining that the height of the second rib 140 is greater than or equal to 5 mm, the blocking effect of the second rib 140 on the liquid can be ensured, the difficulty for the liquid to cross the second rib 140 can be increased, and thus the protection effect of the second rib 140 on the motor 120 can be enhanced.

[0087] By defining that the height of the second rib 140 is less than or equal to 10 mm, on the one hand, the probability of interference between the second rib 140 and the wind wheel 130 can be reduced, and on the other hand, the height of the wind wheel 130 can be reduced, thereby providing convenient conditions for the ultra-thin design of the range hood assembly 100.

[0088] As Figure 5 and Figure 6 shown, in some embodiments of the present invention, optionally, the bottom wall of the housing 110 includes a second guiding surface 1108, and the second guiding surface 1108 is located outside the second rib 140; the second guiding surface 1108 slopes downward in the direction from the second rib 140 to the outlet 1106.

[0089] In this embodiment, the bottom wall of the housing 110 is further provided with a second guiding surface 1108, and the second guiding surface 1108 is located outside the second rib 140. When the number of the second ribs 140 is multiple, the second guiding surface 1108 is located outside the outermost second rib 140.

[0090] Among them, the second flow guiding surface 1108 slopes downward in the direction from the second rib 140 to the outlet 1106, that is, the height of the second flow guiding surface 1108 gradually decreases in the direction close to the outlet 1106. By providing the inclined second flow guiding surface 1108, the liquid outside the second rib 140 can flow to the outlet 1106 by its own gravity and is finally discharged from the outlet 1106 to the outside of the housing 110, avoiding the accumulation of liquid inside the housing 110 and preventing the excessively accumulated liquid from crossing the second rib 140. Thereby, the drainage rate of the housing 110 is improved, the probability of the motor 120 being damaged by liquid is reduced, and further the waterproof ability of the range hood assembly 100 is improved, the failure rate of the motor 120 is reduced, and the technical effects of improving the safety and reliability of the range hood assembly 100 are achieved.

[0091] As Figure 6 shown, in some embodiments of the present invention, optionally, the inclination angle ( Figure 6 where α is shown) of the second flow guiding surface 1108 ranges from: greater than or equal to 1°, and less than or equal to 6°.

[0092] In this embodiment, the inclination angle of the second flow guiding surface 1108 with respect to the horizontal plane 300 needs to be greater than or equal to 1°, and less than or equal to 6°.

[0093] By defining that the inclination angle of the second flow guiding surface 1108 is greater than or equal to 1°, it can be ensured that the liquid can converge towards the outlet 1106 and avoid the accumulation of liquid in the housing 110. By defining that the inclination angle of the second flow guiding surface 1108 is less than or equal to 6°, the thickness of the housing 110 can be reduced on the basis of meeting the requirement of self-discharge of the liquid, thereby providing convenient conditions for the ultra-thin design of the range hood assembly 100, and making the integrated stove 200 equipped with the range hood assembly 100 suitable for small-sized cabinets.

[0094] Specifically, the inclination angle of the second flow guiding surface 1108 can be selected as 2°, 4° or 5° for drainage without excessively increasing the thickness of the range hood assembly 100.

[0095] As Figure 1 and Figure 2 shown, the second aspect of the present invention provides an integrated stove 200, which includes: a main body 210, the main body 210 includes a smoke inlet 2102 and a smoke outlet 2104, the main body 210 internally includes a flue 2106 and a drainage channel 2108, the flue 2106 communicates with the smoke inlet 2102 and the smoke outlet 2104, and the drainage channel 2108 communicates with the flue 2106 and the outside of the main body 210; the range hood assembly 100 as in any of the above embodiments, the housing 110 is connected to the main body 210, and the cavity 1102 communicates with the smoke outlet 2104; an oil separation assembly 220, the oil separation assembly 220 is disposed in the flue 2106, and the oil separation assembly 220 is used for separating the oil in the oil fume.

[0096] In this embodiment, an integrated stove 200 provided with the smoke machine assembly 100 in any of the above embodiments is defined. Therefore, the integrated stove 200 has the advantages of the smoke machine assembly 100 in any of the above embodiments and can achieve the technical effects that the smoke machine assembly 100 in any of the above embodiments can achieve. To avoid repetition, it will not be elaborated here.

[0097] On this basis, the integrated stove 200 includes a main body 210 and an oil-grease separation component 220.

[0098] The main body 210 is the main frame structure of the integrated stove 200. The top of the main body 210 forms the countertop of the integrated stove 200, and cooking utensils are heated on the countertop. A smoke inlet 2102 is opened on the countertop. A flue 2106 is formed inside the main body 210, and a smoke outlet 2104 is also opened at the bottom of the main body 210. The first end of the flue 2106 is communicated with the smoke inlet 2102, and the second end of the flue 2106 is communicated with the smoke outlet 2104. The integrated stove 200 sucks external oil fume through the smoke inlet 2102. After the oil fume enters the flue 2106, it is filtered in the flue 2106, and the filtered oil fume is discharged from the flue 2106 through the smoke outlet 2104.

[0099] The oil-grease separation component 220 is arranged in the flue 2106 and is disposed opposite to the smoke inlet 2102 on the flue 2106. After the oil fume flows into the smoke inlet 2102, it needs to flow through the oil-grease separation component first. The oil-grease separation component 220 can separate the oil and water vapor mixed in the oil fume, complete the pre-stage oil-water separation of the oil fume, and prevent the oil fume from carrying oil and water into the smoke machine assembly 100. Thus, on the one hand, it protects the smoke machine assembly 100 from being polluted by oil and water, extends the service life of the integrated stove 200; on the other hand, it avoids the oil and water accumulated in the flue 2106 from generating peculiar smells; and on the third hand, it avoids the oil fume processed by the integrated stove 200 from causing secondary pollution to the environment.

[0100] Wherein, a drainage channel 2108 is also arranged inside the main body 210, and the drainage channel 2108 can discharge the liquid separated by the oil-grease separation component 220 to the outside of the main body 210, thereby preventing the liquid from accumulating excessively in the main body 210.
