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 device that integrates a cooking stove and a range hood. Generally, a 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 related technologies, the motor is mostly fixed inside the volute through connection structures such as screws. The motor needs to rotate at a high speed during operation to generate sufficient negative pressure suction.

[0004] However, the high-speed rotating motor will generate jitter and vibration, which will be transmitted to the whole machine, increasing the working noise. The jitter and vibration will also affect the stability of the connection structure, causing the motor to loosen and misalign. As a result, the smoke stove integrated machine has technical problems of high working noise and poor motor positioning stability. 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 cavity and is connected to the housing; a buffer member, the buffer member is arranged between the motor and the housing, and the buffer member is used for absorbing the impact force of the motor on the housing.

[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 for positioning and supporting 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 arranged 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 for driving 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. Specifically, the motor is connected to the housing, and the motor is fixed inside the housing after assembly.

[0011] On this basis, a buffer component is provided between the motor and the housing. The buffer component is made of a material such as rubber that can absorb impacts. After the connection between the motor and the housing is completed, the buffer component can be clamped and positioned between the two. During the high-speed rotation of the motor, the buffer component can absorb the impact force generated by the motor through deformation between the motor and the housing, so as to prevent the jitter and vibration on the motor from being transmitted to the housing, thereby reducing the jitter amplitude and vibration amplitude of the housing and the entire range hood assembly, and thus reducing the working noise of the range hood assembly, and further solving the technical problem of high working noise existing in the related art.

[0012] Moreover, the buffer component that absorbs impacts between the motor and the housing can also reduce the impact on the connecting components between the motor and the housing, reduce the probability of loosening or even falling off of the connecting components under jitter and vibration, and improve the positioning stability of the motor, thereby solving the technical problem of poor motor positioning stability existing in the related art.

[0013] At the same time, the transmitted jitter and vibration will also cause gaps between the housing, the motor and the connecting components. Sewage and grease inside the housing may leak to the outside of the range hood assembly through the gaps, causing pollution. In this regard, absorbing impacts through the buffer component can also inhibit the generation of the above-mentioned gaps, thereby reducing the probability of liquid and grease leakage.

[0014] Thus, by setting the buffer component, the technical effects of reducing the working noise of the range hood assembly, improving the working stability and reliability of the motor, and enhancing the sealing performance of the range hood assembly are achieved.

[0015] Specifically, the material of the buffer component is selected as nitrile rubber, and nitrile rubber has excellent oil resistance, thereby extending the service life of the buffer component.

[0016] The hardness range of the buffer component is: greater than or equal to HS30 and less than or equal to HS70. By limiting the above hardness range, by limiting the hardness of the buffer component to be greater than or equal to HS30, it can ensure that the buffer component has sufficient strength and elasticity, so as to achieve the effects of shock absorption and screw loosening prevention. By limiting the hardness of the buffer component to be less than or equal to HS70, the buffer component can be made soft enough so that the buffer component can be smoothly pressed into the predetermined installation position, thereby reducing the assembly difficulty of the buffer component.

[0017] In addition, the above range hood assembly provided by the present invention may also have the following additional technical features:

[0018] In some technical solutions of the present invention, optionally, the housing includes a first mounting hole, the motor includes a fixing portion, the fixing portion is provided with a second mounting hole, the first mounting hole and the second mounting hole are opposite, and the range hood assembly further includes: a connecting component, the connecting component passes through the second mounting hole, and the connecting component is used to clamp the buffer component between the housing and the motor by connecting the fixing portion and the housing.

[0019] In this technical solution, a first mounting hole is provided at the bottom of the housing, and the first mounting hole communicates the inside and outside of the housing. Correspondingly, the motor includes a fixing portion, and a second mounting hole is provided on the fixing portion. During the assembly process, the first mounting hole needs to be aligned with the second mounting hole. Specifically, the fixing portion can be a fixing foot on the motor bracket.

[0020] On this basis, the motor and the housing are connected by a connecting component. After the first mounting hole and the second mounting hole are aligned, the connecting component is screwed into the second mounting hole to shorten the distance between the head of the connecting component and the fixing portion, so as to clamp and position the housing and the buffer component through the fixing portion and the head of the connecting component, ensuring that the buffer component can absorb the impact force between the housing and the fixing portion.

[0021] It can be seen that the connecting structure provided by this technical solution can complete the positioning and installation of the buffer component while connecting the motor and the housing, enabling the buffer component to be accurately assembled to the predetermined position without relying on other positioning structures, thereby achieving the technical effects of reducing the structural complexity and assembly complexity of the range hood assembly and improving the reliability of the buffer component.

[0022] Specifically, the connecting component includes: a combination of a bolt, a stud and a nut, a screw, etc.

[0023] In some technical solutions of the present invention, optionally, the fixing portion passes through the first mounting hole, and the buffer component includes: a first cushion block. In the radial direction of the first mounting hole, the first cushion block is located between the hole wall of the first mounting hole and the fixing portion; wherein, the circumferential side of the first cushion block includes a first rib and a second rib; in the axial direction of the first mounting hole, the first rib is clamped between the connecting component and the outer surface of the housing, and the second rib is clamped between the motor and the inner surface of the housing.

[0024] In this technical solution, the fixing portion extends out relative to the motor, and the buffer component includes a first cushion block. The circumferential side of the first cushion block is provided with a first rib and a second rib. The first rib and the second rib are annular, and the first rib and the second rib are spaced apart in the axial direction to form a slot therebetween.

[0025] During the assembly process, first press the first cushion block into the first mounting hole provided at the bottom of the housing, where the first rib is located inside the housing and the second rib is located outside the housing. The first rib and the second rib jointly clamp the housing, thereby realizing the preliminary positioning of the first cushion block and preventing the first cushion block from falling off from the first mounting hole.

[0026] After the preliminary positioning of the first cushion block is completed, insert the fixing portion into the first cushion block to complete the preliminary positioning of the motor. In this case, the first cushion block is clamped by the inner surface of the first mounting hole and the outer surface of the fixing portion, and cooperate with the aforementioned first rib and second rib to realize the axial positioning and radial positioning of the first cushion block.

[0027] After inserting the fixed part into the first cushion block, screw the connecting component into the second mounting hole in the fixed part. As the screwing depth increases, the head of the connecting component gradually presses against the first rib of the first cushion block until the head of the connecting component abuts against the outer end face of the fixed part to complete the assembly.

[0028] After the assembly is completed, the first rib is clamped between the head of the connecting component and the outer surface of the housing, and the second rib is clamped between the lower surface of the motor and the inner surface of the housing. Thus, on the one hand, the impact force transmitted from the motor to the housing is absorbed by the first rib and the second rib to reduce the working noise, and on the other hand, the sealing on both the inner and outer sides is achieved through the first rib and the second rib.

[0029] It can be seen that by providing the first cushion block embedded in the first mounting hole and the fixed part inserted into the first cushion block, a nested assembly method is formed, thereby improving the radial assembly accuracy. On this basis, the positioning in the axial direction is completed by screwing in the connecting component to ensure that the motor and the buffer component can be accurately positioned at the predetermined position, and further achieve the technical effects of improving the positioning accuracy of the motor and the buffer component and enhancing the structural stability of the range hood assembly.

[0030] In some technical solutions of the present utility model, optionally, in the axial direction of the first mounting hole, the size range of the first rib is: greater than or equal to 1 mm and less than or equal to 5 mm; and / or in the axial direction of the first mounting hole, the size range of the second rib is: greater than or equal to 1 mm and less than or equal to 5 mm.

[0031] In this technical solution, in the axial direction of the first mounting hole, the size of the first rib is the thickness of the first rib. Among them, the thickness of the first rib needs to be greater than or equal to 1 mm and less than or equal to 5 mm. By limiting the thickness of the first rib to be greater than or equal to 1 mm, it can be ensured that the first rib can separate the outer surface of the housing and the head of the connecting component, avoiding rigid contact between the connecting component and the housing due to the too thin first rib, thereby improving the impact force absorption effect of the buffer component, further reducing the working noise of the range hood assembly, and enhancing the connection stability of the connecting component. By limiting the thickness of the first rib to be less than or equal to 5 mm, the distance between the head of the connecting component and the outer surface of the housing can be shortened on the basis of meeting the impact absorption requirements, thereby improving the structural compactness of the range hood assembly and providing convenient conditions for the miniaturized design of the range hood assembly.

[0032] In the axial direction of the first mounting hole, the dimension of the second rib is the thickness of the second rib. Among them, the thickness of the second rib needs to be greater than or equal to 1 mm and less than or equal to 5 mm. By defining that the thickness of the second rib is greater than or equal to 1 mm, it can be ensured that the second rib can separate the inner surface of the housing and the motor, avoiding rigid contact between the motor and the housing due to the too thin second rib, thereby improving the impact absorption effect of the buffer component, further reducing the working noise of the range hood assembly, and improving the connection stability of the motor. By defining that the thickness of the second rib is less than or equal to 5 mm, the distance between the motor and the inner surface of the housing can be shortened on the basis of meeting the impact absorption requirements, thereby improving the structural compactness of the range hood assembly and providing convenient conditions for the miniaturized design of the range hood assembly.

[0033] In some technical solutions of the present utility model, optionally, the first cushion block is an elastic structure; in the case of not connecting the screw and in the axial direction of the first mounting hole, the outer end surface of the first cushion block protrudes from the outer end surface of the fixing part.

[0034] In this technical solution, the first cushion block is an elastic structure, and the first cushion block can change its shape through deformation when being pressed, and specifically, the first cushion block can be prepared by rubber material.

[0035] On this basis, after the pre-assembly of the first cushion block and the motor is completed and the connecting component is not screwed in, the outer end surface of the first cushion block protrudes from the outer end surface of the fixing part.

[0036] Subsequently, during the process of screwing in the connecting component, the head of the connecting component gradually approaches the outer end surface of the fixing part until the head of the connecting component abuts against the outer end surface of the fixing component. During this process, a part of the first cushion block protruding from the end surface of the fixing component is compressed and deformed by the head of the connecting component, thereby sealing the gap between the first mounting hole and the first cushion block and the gap between the first cushion block and the fixing part through deformation, and further achieving the technical effect of enhancing the sealing performance of the range hood assembly.

[0037] Specifically, when the connecting component is a screw, the head of the connecting component is a screw head.

[0038] When the connecting component is a bolt, the head of the connecting component is a bolt head.

[0039] When the connecting component is a combination of a stud and a nut, the head of the connecting component is a nut.

[0040] In some technical solutions of the present utility model, optionally, in the axial direction of the first mounting hole, the range of the distance between the outer end surface of the first cushion block and the outer end surface of the fixing part is: greater than or equal to 0.5 mm and less than or equal to 4 mm.

[0041] In this technical solution, when the connecting component is not screwed in, the distance between the outer end surface of the first cushion block and the outer end surface of the fixing part needs to be greater than or equal to 0.5 mm and less than or equal to 4 mm.

[0042] By defining that the above distance is greater than or equal to 0.5 mm, problems such as insufficient deformation and insufficient extrusion force of the first cushion block can be avoided. Thus, on the one hand, the motor can be effectively fixed, and on the other hand, the anti-loosening design of the connecting component can be achieved.

[0043] By defining that the above distance is greater than or equal to 4 mm, problems such as excessive deformation of the first cushion block and the head of the connecting component not being able to be screwed to the end surface of the fixing part can be avoided. And even if the head of the connecting component is forcibly screwed to the end surface of the fixing part, it will cause the first cushion block to be damaged due to excessive deformation beyond the limit, thereby achieving the technical effect of improving the positioning reliability of the motor.

[0044] In some technical solutions of the present utility model, optionally, in the radial direction of the first mounting hole, the range of the clearance fit between the first mounting hole and the first cushion block is: greater than or equal to -0.5 mm and less than or equal to 0.5 mm; and / or in the radial direction of the first mounting hole, the range of the clearance fit between the first cushion block and the fixing part is: greater than or equal to -0.5 mm and less than or equal to 0.5 mm.

[0045] In this technical solution, the clearance fit between the first mounting hole and the first cushion block is defined. Specifically, the first mounting hole and the first cushion block can be interference fit, transition fit, or clearance fit. By defining that the clearance fit is greater than or equal to -0.5 mm and less than or equal to 0.5 mm, the positioning reliability and sealing effectiveness can be ensured.

[0046] This technical solution also defines the clearance fit between the first cushion block and the fixing part inserted into its inner side. Specifically, the fixing part and the first cushion block can be interference fit, transition fit, or clearance fit. By defining that the clearance fit is greater than or equal to -0.5 mm and less than or equal to 0.5 mm, the positioning reliability and sealing effectiveness can be ensured.

[0047] In some technical solutions of the present utility model, optionally, the buffer component includes: a first washer, which is clamped between the fixing part and the inner surface of the housing; a second cushion block, which is clamped between the first washer and the connecting component, and the second cushion block is located between the connecting component and the hole wall of the first mounting hole.

[0048] In this technical solution, the buffer component includes a first washer and a second spacer. Among them, the first washer is arranged between the motor and the inner surface of the housing, and the washer is provided with a first opening. The second spacer is embedded inside the first mounting hole, and the second spacer is provided with a second opening, and the second mounting hole, the first opening, and the second opening are aligned. After the pre-assembly of the first washer and the second spacer is completed, the connecting component is screwed into the second mounting hole through the second opening and the first opening, so as to clamp the first washer between the motor and the inner surface of the housing, and clamp the second spacer between the head of the connecting component and the outer surface of the housing. At the same time, radial positioning of the second spacer is provided through the first mounting hole and the connecting component, so as to absorb the impact force of the motor through the first washer and the second spacer, and enhance the sealing performance at the first mounting hole through the first washer and the second spacer, thereby achieving the technical effects of reducing the working noise of the range hood assembly, improving the working stability and reliability of the motor, and enhancing the sealing performance of the range hood assembly.

[0049] At the same time, by setting the first washer, the buffer absorption area can be increased between the motor and the housing to improve the impact force absorption effect, thereby reducing the working noise and the probability of loosening of the connecting component. By setting the second spacer separated from the first washer, the assembly complexity of the second spacer can be reduced. Specifically, the second spacer can be directly inserted into the first mounting hole without forcibly clamping the second spacer through a pressing action.

[0050] In some technical solutions of the present utility model, optionally, the range hood assembly further includes: a second washer, and the second washer is clamped between the head of the connecting component and the buffer component.

[0051] In this technical solution, a second washer is further arranged between the head of the connecting component and the buffer component. The second washer can replace the head of the connecting component to squeeze the buffer component, thereby providing a larger squeezing area for the buffer component, avoiding the head of the connecting component from being unable to effectively press the buffer component due to spreading the buffer component, and thus improving the positioning accuracy and positioning reliability of the buffer component.

[0052] At the same time, increasing the squeezing area can also enable the connecting component to withstand more impact forces, thereby reducing the probability of loosening of the connecting component, and thus improving the positioning stability.

[0053] In some technical solutions of the present utility model, optionally, the outer diameter of the second washer is greater than the aperture of the first mounting hole.

[0054] In this technical solution, by defining that the outer diameter of the second washer is greater than the aperture of the first mounting hole, the probability of the shock pad loosening due to elastic deformation under a large impact can be further reduced, thereby enhancing the positioning stability and sealing reliability.

[0055] In a second aspect of the present utility model, an integrated stove is provided. The integrated stove includes: a main body, and the main body includes a flue; a smoke machine assembly as in any of the above technical solutions, the housing is connected to the main body, and the cavity is communicated with the flue.

[0056] In this technical solution, an integrated stove provided with a smoke machine assembly as 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.

[0057] On this basis, the integrated stove includes a main body and an oil separation assembly.

[0058] 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 provided on the cooking surface. A flue is formed inside the main body, and a smoke outlet is also provided at the bottom of the main body. The first end of the flue is communicated with the smoke inlet, and the second end of the flue is communicated with the smoke outlet. The integrated stove sucks external cooking fumes through the smoke inlet, and the cooking fumes enter the flue and are filtered in the flue, and the filtered cooking fumes are discharged from the flue through the smoke outlet.

Detailed implementation manners

[0077] In order to be able to more clearly understand the above-mentioned objects, features and advantages of the present utility model, the present utility model will be further described in detail below with reference to the drawings and specific implementation manners. 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.

[0078] 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.

[0079] Refer to the following Figures 1 to 14 to describe a range hood assembly and an integrated stove according to some embodiments of the present utility model.

[0080] As shown in Figure 1 , Figure 2 , Figure 3 and Figure 4 An embodiment of the present utility model proposes a range hood assembly 100, which includes: a housing 110, the housing 110 includes a cavity 1102; a motor 120, the motor 120 is arranged in the cavity 1102 and is connected to the housing 110; a buffer member 130, the buffer member 130 is arranged between the motor 120 and the housing 110, and the buffer member 130 is used to absorb the impact force of the motor 120 on the housing 110.

[0081] Figure 2 In, arrow b shows the flow direction of the oil fume, and arrow c shows the rotation direction of the impeller.

[0082] Figure 4 In, arrow d shows the acting direction of the elastic force.

[0083] The present application proposes a range hood assembly 100, which belongs to the power structure on the integrated stove 200. Specifically, the range hood assembly 100 can suck oil fume and discharge the sucked oil fume to a designated area through the flue 2102.

[0084] The range hood assembly 100 includes a housing 110, a motor 120 and an impeller. The housing 110 is the main frame structure of the range hood assembly 100 and is used to position and support other working structures on the range hood assembly 100. A cavity 1102 is formed inside the housing 110, and an oil fume inlet and an oil fume outlet communicating the cavity 1102 and the external space of the housing 110 are arranged 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 impeller. The motor 120 is used to drive the impeller to rotate, so as to suck the oil fume into the housing 110 through the oil fume inlet by the impeller, and discharge the oil fume out of the housing 110 through the oil fume outlet after pressurization and acceleration, thereby realizing the suction and centralized discharge of the oil fume. Specifically, the motor 120 is connected to the housing 110, and after assembly, the motor 120 is fixed inside the housing 110.

[0085] On this basis, a buffer member 130 is provided between the motor 120 and the housing 110. The buffer member 130 is made of a material such as rubber that can absorb impacts. After the connection between the motor 120 and the housing 110 is completed, the buffer member 130 can be clamped and positioned between them. During the high-speed rotation of the motor 120, the buffer member 130 can absorb the impact force generated by the motor 120 through deformation between the motor 120 and the housing 110, so as to prevent the jitter and vibration on the motor 120 from being transmitted to the housing 110, thereby reducing the jitter amplitude and vibration amplitude of the housing 110 and the entire range hood assembly 100, and thus reducing the working noise of the range hood assembly 100, and further solving the technical problem of large working noise in the related art.

[0086] Moreover, the buffer member 130 that absorbs impacts between the motor 120 and the housing 110 can also reduce the impact on the connecting member 140 between the motor 120 and the housing 110, and reduce the probability of loosening or even falling off of the connecting member 140 under jitter and vibration, improving the positioning stability of the motor 120, and thus solving the technical problem of poor positioning stability of the motor 120 in the related art.

[0087] At the same time, the transmitted jitter and vibration to the housing 110 will also cause gaps to form between the housing 110, the motor 120 and the connecting member 140. Sewage and grease inside the housing 110 may leak to the outside of the range hood assembly 100 through the gaps, causing pollution. In this regard, absorbing impacts through the buffer member 130 can also suppress the generation of the above gaps, thereby reducing the probability of liquid and grease leakage.

[0088] Thus, by providing the buffer member 130, the technical effects of reducing the working noise of the range hood assembly 100, improving the working stability and reliability of the motor 120, and enhancing the sealing performance of the range hood assembly 100 are achieved.

[0089] Specifically, the material of the buffer member 130 is selected as nitrile rubber, and nitrile rubber has excellent oil resistance, thereby extending the service life of the buffer member 130.

[0090] The hardness range of the buffer member 130 is: greater than or equal to HS30 and less than or equal to HS70. By defining the above hardness range, by defining that the hardness of the buffer member 130 is greater than or equal to HS30, it can be ensured that the buffer member 130 has sufficient strength and elasticity, so as to achieve the effects of shock absorption and screw loosening prevention. By defining that the hardness of the buffer member 130 is less than or equal to HS70, the buffer member 130 can be made soft enough so that the buffer member 130 can be smoothly pressed into the predetermined installation position, thereby reducing the assembly difficulty of the buffer member 130.

[0091] Such as Figure 1 、 Figure 2 、 Figure 3and Figure 4 As shown in Figure 4 , in some embodiments of the present utility model, optionally, the housing 110 includes a first mounting hole 1104, the motor 120 includes a fixing portion 122, the fixing portion 122 is provided with a second mounting hole 1222, the first mounting hole 1104 and the second mounting hole 1222 are opposite to each other, and the range hood assembly 100 further includes: a connecting member 140, the connecting member 140 is inserted through the second mounting hole 1222, and the connecting member 140 is used to clamp the buffer member 130 between the housing 110 and the motor 120 by connecting the fixing portion 122 and the housing 110.

[0092] In this embodiment, a first mounting hole 1104 is opened at the bottom of the housing 110, and the first mounting hole 1104 communicates with the inside and outside of the housing 110. Correspondingly, the motor 120 includes a fixing portion 122, and a second mounting hole 1222 is opened on the fixing portion 122. During the assembly process, the first mounting hole 1104 needs to be aligned with the second mounting hole 1222. Specifically, the fixing portion 122 can be a fixing foot on the motor 120 bracket.

[0093] On this basis, the motor 120 and the housing 110 are connected by the connecting member 140. After the first mounting hole 1104 and the second mounting hole 1222 are aligned, the connecting member 140 is screwed into the second mounting hole 1222 to shorten the distance between the head of the connecting member 140 and the fixing portion 122, so as to clamp and position the housing 110 and the buffer member 130 through the fixing portion 122 and the head of the connecting member 140, ensuring that the buffer member 130 can absorb the impact force between the housing 110 and the fixing portion 122.

[0094] It can be seen that the connection structure provided by this embodiment can complete the positioning and installation of the buffer member 130 while connecting the motor 120 and the housing 110, so that the buffer member 130 can be accurately assembled to the predetermined position without relying on other positioning structures, thereby achieving the technical effects of reducing the structural complexity and assembly complexity of the range hood assembly 100 and improving the reliability of the buffer member 130.

[0095] Specifically, the connecting member 140 includes: a combination of a bolt, a stud and a nut, a screw, etc.

[0096] Such as Figure 3 、 Figure 6 、 Figure 7 、 Figure 8 and Figure 9 As shown in Figure 8 and Figure 9 , in some embodiments of the present utility model, optionally, the fixing portion 122 is inserted through the first mounting hole 1104, and the buffer member 130 includes: a first cushion block 132, in the radial direction of the first mounting hole 1104 ( Figure 3On the arrow e shown in the figure, the first cushion block 132 is located between the hole wall of the first mounting hole 1104 and the fixing portion 122; wherein, the circumferential side of the first cushion block 132 includes a first rib 1322 and a second rib 1324; in the axial direction of the first mounting hole 1104 ( Figure 3 On the arrow f shown in the figure), the first rib 1322 is clamped between the connecting member 140 and the outer surface of the housing 110, and the second rib 1324 is clamped between the motor 120 and the inner surface of the housing 110.

[0097] In this embodiment, the fixing portion 122 extends outward relative to the motor 120, the buffer member 130 includes a first cushion block 132, the circumferential side of the first cushion block 132 is provided with a first rib 1322 and a second rib 1324, the first rib 1322 and the second rib 1324 are annular, and the first rib 1322 and the second rib 1324 are spaced apart in the axial direction to form a slot therebetween.

[0098] During the assembly process, first press the first cushion block 132 into the first mounting hole 1104 opened at the bottom of the housing 110, wherein the first rib 1322 is located inside the housing 110, the second rib 1324 is located outside the housing 110, and the first rib 1322 and the second rib 1324 jointly clamp the housing 110, thereby realizing the pre-positioning of the first cushion block 132 and preventing the first cushion block 132 from falling off from the first mounting hole 1104.

[0099] After completing the pre-positioning of the first cushion block 132, insert the fixing portion 122 into the first cushion block 132 to complete the pre-positioning of the motor 120. In this case, the first cushion block 132 is clamped by the inner surface of the first mounting hole 1104 and the outer surface of the fixing portion 122, and the axial positioning and radial positioning of the first cushion block 132 are realized in cooperation with the aforementioned first rib 1322 and second rib 1324.

[0100] After inserting the fixing portion 122 into the first cushion block 132, screw the connecting member 140 into the second mounting hole 1222 in the fixing portion 122. As the screwing depth increases, the head of the connecting member 140 gradually presses the first rib 1322 of the first cushion block 132 until the head of the connecting member 140 abuts against the outer end face of the fixing portion 122 to complete the assembly.

[0101] After completing the assembly, the first rib 1322 is clamped between the head of the connecting member 140 and the outer surface of the housing 110, and the second rib 1324 is clamped between the lower surface of the motor 120 and the inner surface of the housing 110. Thus, on the one hand, the impact force transmitted from the motor 120 to the housing 110 is absorbed by the first rib 1322 and the second rib 1324 to reduce the working noise, and on the other hand, the sealing on both the inner and outer sides is realized by the first rib 1322 and the second rib 1324.

[0102] It can be seen that by providing the first cushion block 132 embedded in the first mounting hole 1104 and the fixing portion 122 inserted into the first cushion block 132, a nested assembly method is formed, thereby improving the radial assembly accuracy. On this basis, the positioning in the axial direction is completed by screwing in the connecting component 140, so as to ensure that the motor 120 and the buffer component 130 can be accurately positioned at the predetermined position, and further achieve the technical effects of improving the positioning accuracy of the motor 120 and the buffer component 130 and enhancing the structural stability of the range hood assembly 100.

[0103] As Figure 3 shown, in some embodiments of the present invention, optionally, in the axial direction of the first mounting hole 1104, the dimension D1 of the first rib 1322 ranges from: greater than or equal to 1 mm and less than or equal to 5 mm; and / or in the axial direction of the first mounting hole 1104, the dimension D2 of the second rib 1324 ranges from: greater than or equal to 1 mm and less than or equal to 5 mm.

[0104] In this embodiment, in the axial direction of the first mounting hole 1104, the dimension of the first rib 1322 is the thickness of the first rib 1322. Among them, the thickness of the first rib 1322 needs to be greater than or equal to 1 mm and less than or equal to 5 mm. By defining that the thickness of the first rib 1322 is greater than or equal to 1 mm, it can be ensured that the first rib 1322 can separate the outer surface of the housing 110 and the head of the connecting component 140, avoiding rigid contact between the connecting component 140 and the housing 110 due to the too thin first rib 1322, thereby improving the impact absorption effect of the buffer component 130, and further reducing the working noise of the range hood assembly 100 and enhancing the connection stability of the connecting component 140. By defining that the thickness of the first rib 1322 is less than or equal to 5 mm, the distance between the head of the connecting component 140 and the outer surface of the housing 110 can be shortened on the basis of meeting the impact absorption requirements, thereby improving the structural compactness of the range hood assembly 100 and providing convenient conditions for the miniaturized design of the range hood assembly 100.

[0105] In the axial direction of the first mounting hole 1104, the dimension of the second rib 1324 is the thickness of the second rib 1324. Among them, the thickness of the second rib 1324 needs to be greater than or equal to 1 mm and less than or equal to 5 mm. By limiting the thickness of the second rib 1324 to be greater than or equal to 1 mm, it can be ensured that the second rib 1324 can separate the inner surface of the housing 110 and the motor 120, avoiding rigid contact between the motor 120 and the housing 110 due to the too thin second rib 1324, thereby improving the impact absorption effect of the buffer member 130, further reducing the working noise of the range hood assembly 100, and enhancing the connection stability of the motor 120. By limiting the thickness of the second rib 1324 to be less than or equal to 5 mm, the distance between the inner surface of the motor 120 and the housing 110 can be shortened on the basis of meeting the impact absorption requirements, thereby improving the structural compactness of the range hood assembly 100 and providing convenient conditions for the miniaturization design of the range hood assembly 100.

[0106] As Figure 3 and Figure 4 shown, in some embodiments of the present invention, optionally, the first cushion block 132 is an elastic structure; in the case of not connecting the screw and in the axial direction of the first mounting hole 1104, the outer end surface of the first cushion block 132 protrudes from the outer end surface of the fixing portion 122.

[0107] In this embodiment, the first cushion block 132 is an elastic structure, and the first cushion block 132 can change its shape through deformation when being compressed. Specifically, the first cushion block 132 can be prepared by rubber material.

[0108] On this basis, after the pre-assembly of the first cushion block 132 and the motor 120 is completed and the connecting member 140 is not screwed in, the outer end surface of the first cushion block 132 protrudes from the outer end surface of the fixing portion 122.

[0109] Subsequently, during the process of screwing in the connecting member 140, the head of the connecting member 140 gradually approaches the outer end surface of the fixing portion 122 until the head of the connecting member 140 abuts against the outer end surface of the fixing portion 122. During this process, a part of the first cushion block 132 protruding from the end surface of the fixing portion 122 is compressed and deformed by the head of the connecting member 140, thereby sealing the gap between the first mounting hole 1104 and the first cushion block 132 and the gap between the first cushion block 132 and the fixing portion 122 through deformation, and further achieving the technical effect of enhancing the sealing performance of the range hood assembly 100.

[0110] Specifically, when the connecting member 140 is a screw, the head of the connecting member 140 is a screw head.

[0111] When the connecting member 140 is a bolt, the head of the connecting member 140 is a bolt head.

[0112] When the connecting component 140 is a combination of a stud and a nut, the head of the connecting component 140 is a nut.

[0113] As Figure 3 and Figure 4 shown, in some embodiments of the present utility model, optionally, in the axial direction of the first mounting hole 1104, the range of the distance H between the outer end surface of the first cushion block 132 and the outer end surface of the fixing portion 122 is: greater than or equal to 0.5 mm and less than or equal to 4 mm.

[0114] In this embodiment, when the connecting component 140 is not screwed in, the distance between the outer end surface of the first cushion block 132 and the outer end surface of the fixing portion 122 needs to be greater than or equal to 0.5 mm and less than or equal to 4 mm.

[0115] By defining the above distance to be greater than or equal to 0.5 mm, problems such as insufficient deformation and insufficient extrusion force of the first cushion block 132 can be avoided. Thus, on the one hand, the motor 120 can be effectively fixed, and on the other hand, the anti-loosening design of the connecting component 140 can be achieved.

[0116] By defining the above distance to be greater than or equal to 4 mm, problems such as excessive deformation of the first cushion block 132 and the head of the connecting component 140 not being able to be screwed to the end surface of the fixing portion 122 can be avoided. And even if the head of the connecting component 140 is forcibly screwed to the end surface of the fixing portion 122, it will cause the first cushion block 132 to be damaged due to excessive deformation beyond the limit, thereby achieving the technical effect of improving the positioning reliability of the motor 120.

[0117] As Figure 3 shown, in some embodiments of the present utility model, optionally, in the radial direction of the first mounting hole 1104, the range of the clearance fit between the first mounting hole 1104 and the first cushion block 132 is: greater than or equal to -0.5 mm and less than or equal to 0.5 mm; and / or in the radial direction of the first mounting hole 1104, the range of the clearance fit a between the first cushion block 132 and the fixing portion 122 is: greater than or equal to -0.5 mm and less than or equal to 0.5 mm.

[0118] In this embodiment, the clearance fit between the first mounting hole 1104 and the first cushion block 132 is defined. Specifically, the first mounting hole 1104 and the first cushion block 132 can be interference fit, transition fit, or clearance fit. By defining the clearance fit to be greater than or equal to -0.5 mm and less than or equal to 0.5 mm, the positioning reliability and sealing effectiveness can be ensured.

[0119] This embodiment also defines the mating clearance between the first cushion block 132 and the fixing part 122 inserted into its inner side. Specifically, the fixing part 122 and the first cushion block 132 can be in interference fit, transition fit, or clearance fit. By defining the mating clearance to be greater than or equal to -0.5 mm and less than or equal to 0.5 mm, the positioning reliability and sealing effectiveness can be ensured.

[0120] As Figure 10 , Figure 11 and Figure 12 shown, in some embodiments of the present utility model, optionally, the buffer member 130 includes: a first washer 134, the first washer 134 is clamped between the fixing part 122 and the inner surface of the housing 110; a second cushion block 136, the second cushion block 136 is clamped between the first washer 134 and the connecting member 140, and the second cushion block 136 is located between the connecting member 140 and the hole wall of the first mounting hole 1104.

[0121] In this embodiment, the buffer member 130 includes a first washer 134 and a second cushion block 136. Among them, the first washer 134 is disposed between the motor 120 and the inner surface of the housing 110, and a first opening is provided on the washer. The second cushion block 136 is embedded inside the first mounting hole 1104, the second cushion block 136 is provided with a second opening, and the second mounting hole 1222, the first opening, and the second opening are aligned. After the pre-assembly of the first washer 134 and the second cushion block 136 is completed, the connecting member 140 is screwed into the second mounting hole 1222 through the second opening and the first opening to clamp the first washer 134 between the motor 120 and the inner surface of the housing 110, and clamp the second cushion block 136 between the head of the connecting member 140 and the outer surface of the housing 110. At the same time, radial positioning of the second cushion block 136 is provided through the first mounting hole 1104 and the connecting member 140. Thus, the impact force of the motor 120 is absorbed by the first washer 134 and the second cushion block 136, and the sealing performance at the first mounting hole 1104 is enhanced by the first washer 134 and the second cushion block 136, thereby achieving the technical effects of reducing the working noise of the range hood assembly 100, improving the working stability and reliability of the motor 120, and enhancing the sealing performance of the range hood assembly 100.

[0122] Meanwhile, by providing the first washer 134, the buffer absorption area can be increased between the motor 120 and the housing 110 to improve the impact force absorption effect, thereby reducing the working noise and reducing the probability of loosening of the connecting member 140. By providing the second cushion block 136 separate from the first washer 134, the assembly complexity of the second cushion block 136 can be reduced. Specifically, the second cushion block 136 can be directly inserted into the first mounting hole 1104 without the need to forcibly snap the second cushion block 136 through a pressing action.

[0123] As Figure 5 and Figure 12As shown, in some embodiments of the present utility model, optionally, the range hood assembly 100 further includes: a second washer 150, which is clamped between the head of the connecting member 140 and the buffer member 130.

[0124] In this embodiment, a second washer 150 is further provided between the head of the connecting member 140 and the buffer member 130. The second washer 150 can replace the head of the connecting member 140 to press the buffer member 130, thereby providing a larger pressing area for the buffer member 130, avoiding that the head of the connecting member 140 cannot effectively press the buffer member 130 due to spreading the buffer member 130, and thus improving the positioning accuracy and positioning reliability of the buffer member 130.

[0125] At the same time, increasing the pressing area can also enable the connecting member 140 to withstand more impact forces, thereby reducing the probability of loosening of the connecting member 140, and thus improving the positioning stability.

[0126] As Figure 5 shown, in some embodiments of the present utility model, optionally, the outer diameter Q1 of the second washer 150 is greater than the aperture Q2 of the first mounting hole 1104.

[0127] In this embodiment, by defining that the outer diameter of the second washer 150 is greater than the aperture of the first mounting hole 1104, the probability of the shock-absorbing pad loosening due to elastic deformation under large impacts can be further reduced, thereby enhancing the positioning stability and sealing reliability.

[0128] As Figure 13 and Figure 14 shown, an embodiment of the present utility model provides an integrated stove 200, which includes: a main body 210, and the main body 210 includes a flue 2102; 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 is communicated with the flue 2102.

[0129] In this embodiment, an integrated stove 200 provided with the range hood assembly 100 as in any of the above embodiments is defined. Therefore, the integrated stove 200 has the advantages of the range hood assembly 100 as in any of the above embodiments, and can achieve the technical effects that the range hood assembly 100 as in any of the above embodiments can achieve. To avoid repetition, it will not be elaborated here.

[0130] On this basis, the integrated stove 200 includes a main body 210 and an oil separation component.

[0131] 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 is provided on the countertop. A flue 2102 is formed inside the main body 210, and a smoke outlet is also provided at the bottom of the main body 210.
