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 cooking stove and a range hood. A smoke stove integrated machine generally includes a volute, an impeller, and a motor. The motor drives the rotating impeller to suck oil fumes.

[0003] In the related art, 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 such as 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 volute, the volute including a cavity; a motor, the motor being disposed inside the volute and connected to the volute; a shock-absorbing member, the shock-absorbing member being disposed in the volute. In the axial direction of the motor, the shock-absorbing member is located between the volute and the motor, and in a second direction, the shock-absorbing member is located between the volute and the motor, the second direction being perpendicular to the axial direction of 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 volute, a motor, and an impeller. The volute is the main frame structure of the smoke machine assembly, which is used to position and support other working structures on the smoke machine assembly. A cavity is formed inside the volute, and an air inlet and an outlet communicating the cavity with the external space of the volute are provided on the volute. The motor is installed in the cavity, and the power output end of the motor is connected to the impeller. The motor is used to drive the impeller to rotate, so as to suck oil fumes into the volute through the air inlet by the impeller, and discharge the oil fumes out of the volute through the outlet after pressurization and acceleration, thereby realizing the suction and centralized discharge of oil fumes. Specifically, the motor is connected to the volute, and the motor is fixed inside the volute after assembly.

[0011] On this basis, a shock-absorbing component is provided between the motor and the volute. The shock-absorbing component is made of a material such as rubber that can absorb shocks. After the connection between the motor and the volute is completed, the shock-absorbing component can be clamped and positioned between the two. Specifically, in the axial direction of the motor, part of the shock-absorbing component is located between the motor and the volute. This part of the shock-absorbing component can absorb vibration shocks in the axial direction of the motor, preventing the vibration shocks in the axial direction from being transmitted to the volute. Correspondingly, in the second direction perpendicular to the axial direction, a part of the shock-absorbing component is located between the volute and the motor. This part of the shock-absorbing component can absorb vibration shocks in the second direction, preventing the lateral vibration shocks from being transmitted to the volute.

[0012] Specifically, during the high-speed rotation of the motor, the shock-absorbing component can absorb the impact force generated by the motor through deformation between the motor and the volute, so as to prevent the jitter and vibration on the motor from being transmitted to the volute, thereby reducing the jitter amplitude and vibration amplitude of the volute and the entire range hood assembly, reducing the working noise of the range hood assembly, and thus solving the technical problem of high working noise in the related art.

[0013] Moreover, the shock-absorbing component that absorbs shocks between the motor and the volute can also reduce the impact on the connecting components between the motor and the volute, 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 in the related art.

[0014] At the same time, the transmitted jitter and vibration will also cause gaps to appear between the volute, the motor and the connecting components. Sewage and grease inside the volute may leak outside the range hood assembly through the gaps, causing pollution. In this regard, absorbing shocks through the shock-absorbing component can also suppress the generation of the above-mentioned gaps, thereby reducing the probability of liquid and grease leakage.

[0015] Thus, by providing the shock-absorbing 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.

[0016] Specifically, the material of the shock-absorbing component is selected as nitrile rubber, which has excellent oil resistance, thus extending the service life of the shock-absorbing component.

[0017] The hardness range of the shock-absorbing 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 shock-absorbing component to be greater than or equal to HS30, it can ensure that the shock-absorbing component has sufficient strength and elasticity, thus achieving the effects of shock absorption and screw loosening prevention. By limiting the hardness of the shock-absorbing component to be less than or equal to HS70, the shock-absorbing component can be made soft enough so that the shock-absorbing component can be smoothly pressed into the predetermined installation position, thereby reducing the assembly difficulty of the shock-absorbing component.

[0018] In addition, the above-mentioned range hood assembly provided by the present utility model may further have the following additional technical features:

[0019] In some technical solutions of the present utility model, optionally, the volute includes a mounting hole, and the shock-absorbing component is embedded in the mounting hole; the shock-absorbing component includes a through hole, and the motor is connected to the volute through the through hole.

[0020] In this technical solution, a mounting hole is formed at the bottom of the volute, the mounting hole communicates with the inside and outside of the volute, the shock-absorbing component is embedded in the mounting hole, a through hole is formed on the shock-absorbing component, the through hole is located inside the mounting hole, and the motor is connected to the volute through the through hole. Specifically, a part of the motor can be inserted into the through hole, or the motor can be connected through a connecting component inserted into the through hole.

[0021] Correspondingly, the motor includes a fixing part, and a threaded hole is formed on the fixing part. During the assembly process, the through hole needs to be aligned with the threaded hole. Specifically, the fixing part can be a fixing foot on the motor bracket.

[0022] On this basis, the motor and the volute are connected through a connecting component. After the through hole and the threaded hole are aligned, the connecting component is screwed into the threaded hole to shorten the distance between the head of the connecting component and the fixing part, so as to clamp and position the volute and the shock-absorbing component through the fixing part and the head of the connecting component, ensuring that the shock-absorbing component can absorb the impact force between the volute and the fixing part.

[0023] It can be seen that the connection structure provided by this technical solution can complete the positioning and installation of the shock-absorbing component while connecting the motor and the volute, enabling the shock-absorbing 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 shock-absorbing component.

[0024] Specifically, the connecting component includes: a combination of a bolt, a stud and a nut, a screw, etc.

[0025] In some technical solutions of the present utility model, optionally, the shock-absorbing component includes: a cushion block, which is inserted through the mounting hole, and the through hole is located in the cushion block; wherein, the peripheral side of the cushion block includes a first rib and a second rib, the first rib is located inside the volute, the second rib is located outside the volute, and the first rib and the second rib clamp the volute.

[0026] In this technical solution, the fixing part extends outwards relative to the motor, the shock-absorbing component includes a cushion block, the peripheral side of the 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.

[0027] During the assembly process, first press the cushion block into the installation hole opened at the bottom of the housing. 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 pre-positioning of the cushion block and preventing the cushion block from falling off from the installation hole.

[0028] After completing the pre-positioning of the cushion block, insert the fixing part into the through hole on the cushion block to complete the pre-positioning of the motor. In this case, the cushion block is clamped by the inner surface of the installation hole and the outer surface of the fixing part, and the axial positioning and radial positioning of the cushion block are realized in cooperation with the aforementioned first rib and second rib.

[0029] Among them, in the axial direction of the motor, the first rib can absorb the axial vibration impact between the motor and the inner surface of the volute. Correspondingly, in the second direction, the cushion block embedded in the installation hole can absorb the lateral vibration impact between the hole wall of the installation hole and the fixing part.

[0030] After inserting the fixing part into the through hole, screw the connecting component into the screw hole in the fixing part to complete the assembly.

[0031] After completing the assembly, the second rib is clamped between the head of the connecting component and the outer surface of the housing, and the first rib is clamped between the lower surface of the motor and the inner surface of the housing. Thus, on the one hand, the first rib and the second rib absorb the impact force transmitted from the motor to the housing to reduce the working noise, and on the other hand, the first rib and the second rib realize the sealing on both the inside and outside.

[0032] It can be seen that by setting the cushion block embedded in the installation hole and the fixing part inserted into the cushion block, a nested assembly method is formed, thereby improving the radial assembly accuracy. On this basis, the axial positioning is completed by screwing in the connecting component to ensure that the motor and the shock-absorbing 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 shock-absorbing component and enhancing the structural stability of the range hood assembly.

[0033] In some technical solutions of the present invention, optionally, one end of the through hole facing the outside of the volute is the outlet, and one end of the through hole facing the inside of the volute is the inlet; the aperture of the inlet is larger than the aperture of the outlet.

[0034] In this technical solution, the through hole includes an inlet and an outlet. The inlet faces the inside of the volute, and the outlet faces the outside of the volute. The fixing part on the motor is inserted into the through hole from the inlet, and the connecting component is inserted into the through hole from the outlet and finally screwed into the screw hole on the fixing part.

[0035] On this basis, the aperture of the inlet is larger than the aperture of the outlet, and in the direction from the inlet to the outlet, the aperture of the through hole gradually decreases.

[0036] By setting an inlet with a larger aperture, the difficulty of inserting the fixing part on the motor into the through hole can be reduced, thereby reducing the assembly difficulty of the motor. By setting an outlet with a smaller aperture and a through hole with a gradually decreasing aperture, the fixing part can squeeze the cushion block during the process of inserting into the through hole, so that the cushion block can effectively fill the space between the fixing part and the hole wall of the mounting hole, thereby improving the shock absorption effect of the cushion block in the second direction on the one hand and improving the sealing effect between the cushion block, the mounting hole and the fixing part on the other hand.

[0037] In some technical solutions of the present utility model, optionally, the outer diameter of the shock-absorbing component is D0; the aperture of the outlet is D1, and D0 and D1 satisfy the relationship: 0.405 ≤ D1÷D0 ≤ 0.477; the aperture of the inlet is D2, and D0 and D2 satisfy the relationship: 0.481 ≤ D2÷D0 ≤ 0.543.

[0038] In this technical solution, the sizes of the inlet and outlet of the through hole are defined.

[0039] D0 is the outer diameter of the shock-absorbing component, and D0 is an input condition. Specifically, D0 can be selected as 16 mm.

[0040] D1 is the aperture of the outlet, 0.405 ≤ D1÷D0 ≤ 0.477. Specifically, D1÷D0 = 0.45 can be selected, that is, D1 = 7.2 mm.

[0041] D2 is the aperture of the inlet, 0.481 ≤ D2÷D0 ≤ 0.543. Specifically, D2÷D0 = 0.49 can be selected, that is, D2 = 7.9 mm.

[0042] By defining the above size relationship, the size matching degree between the through hole and the fixing part on the motor can be improved, thereby improving the shock absorption effect of the cushion block in the second direction.

[0043] In some technical solutions of the present utility model, optionally, the thickness of the second rib is greater than or equal to the thickness of the first rib.

[0044] In this technical solution, the axial direction of the through hole corresponds to the height direction of the shock-absorbing component.

[0045] On this basis, the thickness of the second rib is greater than or equal to the thickness of the first rib, and the second rib is clamped outside the mounting hole. By setting the second rib with a thickness greater than or equal to that of the first rib, the second rib can withstand greater impacts and bear greater stresses, thereby improving the limiting reliability of the second rib on the cushion block, avoiding the misalignment of the first rib and the cushion block towards the inner side of the volute, and further improving the absorption effect of the first rib and the cushion block on vibration and shock.

[0046] In some technical solutions of the present utility model, optionally, the outer diameter of the shock-absorbing component is D0; the thickness of the shock-absorbing component is H0, and D0 and H0 satisfy the relationship: 0.59 ≤ H0÷D0 ≤ 0.72; the thickness of the first rib is H1, and D0 and H1 satisfy the relationship: 0.17 ≤ H1÷D0 ≤ 0.21; the thickness of the second rib is H2, and D0 and H2 satisfy the relationship: 0.28 ≤ H2÷D0 ≤ 0.34.

[0047] In this technical solution, the thicknesses of the first rib and the second rib are defined.

[0048] D0 is the outer diameter of the shock-absorbing component, and D0 is an input condition. Specifically, D0 can be selected as 16 mm.

[0049] H0 is the thickness of the shock-absorbing component, 0.59 ≤ H0÷D0 ≤ 0.72. Specifically, H0÷D0 = 0.66 can be selected, that is, H0 = 10.5 mm.

[0050] H1 is the thickness of the first rib, 0.17 ≤ H1÷D0 ≤ 0.21. Specifically, H1÷D0 = 0.19 can be selected, that is, H1 = 3 mm.

[0051] H2 is the thickness of the second rib, 0.28 ≤ H2÷D0 ≤ 0.34. Specifically, H2÷D0 = 0.31 can be selected, that is, H2 = 5 mm;

[0052] Design the shape and size of the shock-absorbing component according to the above design parameters and matching relationships, which can not only isolate the vibration in the axial direction of the motor, but also isolate the vibration in the second direction of the motor, thereby reducing the vibration acceleration of the range hood assembly and the integrated stove by 36% and reducing the noise by 2.2 dB. Furthermore, the technical effects of improving the working reliability of the range hood assembly and enhancing the user experience are achieved.

[0053] In some technical solutions of the present utility model, optionally, the number of shock-absorbing components is N, and N shock-absorbing components are evenly distributed around the mounting hole. N is an integer greater than or equal to 3.

[0054] In this technical solution, N shock-absorbing components are provided between the motor and the volute, and N shock-absorbing components are evenly distributed around the mounting hole around the mounting hole, that is, the angle between adjacent two mounting holes is the same.

[0055] Among them, N is an integer greater than or equal to 3. Specifically, N can be selected as 3, and the three mounting holes are distributed at an angular interval of 120°.

[0056] By providing multiple shock-absorbing components, the vibration impact generated by the motor on the volute can be shared, and the load on each shock-absorbing component can be reduced. Thus, on the one hand, the shock absorption effect of the shock-absorbing component on the impact is improved, and on the other hand, the probability of the shock-absorbing component being damaged due to the impact is reduced.

[0057] By evenly distributing multiple shock-absorbing components around the mounting hole, the force uniformity of the multiple shock-absorbing components can be improved, avoiding damage to a certain shock-absorbing component due to uneven force, and thus reducing the failure rate of the shock-absorbing components.

[0058] In some technical solutions of the present utility model, optionally, the range hood assembly further includes: an impeller, which is disposed inside the volute and is connected to the motor.

[0059] In this technical solution, the range hood assembly further includes an impeller. The power output end of the motor is connected to the impeller. The motor is used to drive the impeller to rotate, so as to draw the cooking fumes into the volute from the smoke inlet through the impeller, and discharge the cooking fumes from the outlet of the volute after pressurization and acceleration, thereby realizing the suction and centralized discharge of the cooking fumes.

[0060] The second aspect of the present utility model provides an integrated stove, which includes: a main body, and a flue is formed inside the main body; a range hood assembly as described in any of the above technical solutions, the volute is connected to the main body, and the cavity is communicated with the flue.

[0061] In this technical solution, an integrated stove provided with the range hood assembly described in any of the above technical solutions is defined. Therefore, this integrated stove has the advantages possessed by the range hood assembly described in any of the above technical solutions and can achieve the technical effects that the range hood assembly described in any of the above technical solutions can achieve. To avoid repetition, it will not be elaborated here.

[0062] On this basis, the integrated stove includes a main body, and a flue is formed inside the main body. The integrated stove can suck the cooking fumes through the flue to realize the collection of the cooking fumes and avoid the diffusion of the cooking fumes everywhere. An air inlet is opened at the top of the main body, and the air inlet is communicated with the flue. A grille is embedded inside the air inlet to block foreign objects through the grille.

[0063] Among them, the integrated stove further includes an oil-gas separation component and a filtering component.

[0064] The oil-gas separation component is disposed in the flue and is oppositely arranged with the air inlet on the flue. After the cooking fumes flow into the air inlet, they need to flow through the oil-gas separation component first. The oil-gas separation component can separate the oil and water vapor mixed in the cooking fumes, complete the pre-stage oil-water separation of the cooking fumes, avoid the cooking fumes carrying oil and water into the range hood assembly, thereby protecting the range hood assembly from oil and water pollution on the one hand, extending the service life of the integrated stove on the other hand, avoiding the generation of peculiar smell of the oil and water accumulated in the flue on the third hand, and avoiding secondary pollution of the environment by the cooking fumes treated by the integrated stove on the fourth hand.

[0065] The filtering component is installed in the flue, and the cooking fumes flowing in the flue need to pass through the filtering component, so as to filter the cooking fumes through the filtering components in the filtering component, reduce the peculiar smell of the cooking fumes, avoid secondary pollution of the environment by the cooking fumes, and thus achieve the technical effects of improving the reliability of the integrated stove and enhancing the user experience.

Detailed implementation manners

[0085] In order to be able to more clearly understand the above objects, features and advantages of the present invention, the present invention 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 can be combined with each other.

[0086] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention can also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited by the specific embodiments disclosed below.

[0087] Next, refer to Figures 1 to 15 Describe a range hood assembly and an integrated stove according to some embodiments of the present invention.

[0088] As Figure 3 、 Figure 4 And Figure 5 Shown, an embodiment of the present invention provides a range hood assembly 100, and the range hood assembly 100 includes: a volute 110, the volute 110 includes a cavity 1102; a motor 120, the motor 120 is disposed in the volute 110, and the motor 120 is connected to the volute 110; a shock-absorbing component 130, the shock-absorbing component 130 is disposed in the volute 110, in the axial direction of the motor 120 ( Figure 5 Shown by the arrow b in the figure), the shock-absorbing component 130 is located between the volute 110 and the motor 120, and in the second direction ( Figure 5On the arrow c shown in the figure, the shock-absorbing component 130 is located between the volute 110 and the motor 120, and the second direction is perpendicular to the axial direction of the motor 120.

[0089] This application proposes a range hood assembly 100. The range hood assembly 100 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.

[0090] The range hood assembly 100 includes a volute 110, a motor 120, and an impeller 140. The volute 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 volute 110, and an air inlet and an outlet 1304 communicating the cavity 1102 with the external space of the volute 110 are provided on the volute 110. The motor 120 is installed in the cavity 1102, and the power output end of the motor 120 is connected to the impeller 140. The motor 120 is used to drive the impeller 140 to rotate, so as to suck the oil fume into the volute 110 through the impeller 140 from the air inlet, and discharge the oil fume from the outlet 1304 after pressurization and acceleration, thereby realizing the suction and centralized discharge of the oil fume. Specifically, the motor 120 is connected to the volute 110, and after assembly, the motor 120 is fixed inside the volute 110.

[0091] On this basis, a shock-absorbing component 130 is provided between the motor 120 and the volute 110. The shock-absorbing component 130 is made of a material such as rubber that can absorb shocks. After the connection between the motor 120 and the volute 110 is completed, the shock-absorbing component 130 can be clamped and positioned between the two. Specifically, in the axial direction of the motor 120, part of the shock-absorbing component 130 is located between the motor 120 and the volute 110. This part of the shock-absorbing component 130 can absorb vibration shocks in the axial direction of the motor 120 and prevent the vibration shocks in the axial direction from being transmitted to the volute 110. Correspondingly, in the second direction perpendicular to the axial direction, a part of the shock-absorbing component 130 is located between the volute 110 and the motor 120. This part of the shock-absorbing component 130 can absorb vibration shocks in the second direction and prevent the lateral vibration shocks from being transmitted to the volute 110.

[0092] Specifically, during the high-speed rotation of the motor 120, the shock-absorbing component 130 can absorb the impact force generated by the motor 120 through deformation between the motor 120 and the volute 110, so as to prevent the jitter and vibration on the motor 120 from being transmitted to the volute 110, thereby reducing the jitter amplitude and vibration amplitude of the volute 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.

[0093] Moreover, the shock-absorbing component 130 that absorbs shocks between the motor 120 and the volute 110 can also reduce the shocks received by the connecting components between the motor 120 and the volute 110, reduce the probability that the connecting components become loose or even fall off under jitter and vibration, improve the positioning stability of the motor 120, and thus solve the technical problem of poor positioning stability of the motor 120 in the related art.

[0094] At the same time, the jitter and vibration transmitted to the volute 110 will also cause gaps to form between the volute 110, the motor 120, and the connecting components. Sewage and grease inside the volute 110 may leak outside the range hood assembly 100 through the gaps, causing pollution. In this regard, absorbing shocks through the shock-absorbing component 130 can also suppress the generation of the above-mentioned gaps, thereby reducing the probability of liquid and grease leakage.

[0095] Thus, by providing the shock-absorbing component 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.

[0096] Specifically, the material of the shock-absorbing component 130 is selected as nitrile rubber, and nitrile rubber has excellent oil resistance, thereby extending the service life of the shock-absorbing component 130.

[0097] The hardness range of the shock-absorbing component 130 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 shock-absorbing component 130 to be greater than or equal to HS30, it can be ensured that the shock-absorbing component 130 has sufficient strength and elasticity, so as to achieve the effects of shock absorption and screw loosening prevention. By limiting the hardness of the shock-absorbing component 130 to be less than or equal to HS70, the shock-absorbing component 130 can be made soft enough so that the shock-absorbing component 130 can be smoothly pressed into the predetermined installation position, thereby reducing the assembly difficulty of the shock-absorbing component 130.

[0098] As Figure 6 、 Figure 7 and Figure 8 shown, in some embodiments of the present invention, optionally, the volute 110 includes a mounting hole 1104, and the shock-absorbing component 130 is embedded in the mounting hole 1104; the shock-absorbing component 130 includes a through hole 1302, and the motor 120 is connected to the volute 110 through the through hole 1302.

[0099] In this embodiment, an installation hole 1104 is formed at the bottom of the volute 110. The installation hole 1104 communicates with the inside and outside of the volute 110. The shock-absorbing component 130 is embedded in the installation hole 1104. A through hole 1302 is formed in the shock-absorbing component 130. The through hole 1302 is located inside the installation hole 1104, and the motor 120 is connected to the volute 110 through the through hole 1302. Specifically, a part of the motor 120 can be inserted into the through hole 1302, or the motor 120 can be connected through a connecting component inserted into the through hole 1302.

[0100] Correspondingly, the motor 120 includes a fixing part, and a screw hole is formed in the fixing part. During the assembly process, the through hole 1302 needs to be aligned with the screw hole. Specifically, the fixing part can be a fixing foot on the bracket of the motor 120.

[0101] On this basis, the motor 120 and the volute 110 are connected through a connecting component. After the through hole 1302 and the screw hole are aligned, the connecting component is screwed into the screw hole to shorten the distance between the head of the connecting component and the fixing part, so as to clamp and position the volute 110 and the shock-absorbing component 130 through the fixing part and the head of the connecting component, ensuring that the shock-absorbing component 130 can absorb the impact force between the volute 110 and the fixing part.

[0102] It can be seen that the connection structure provided by this embodiment can complete the positioning and installation of the shock-absorbing component 130 while connecting the motor 120 and the volute 110, so that the shock-absorbing component 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 shock-absorbing component 130.

[0103] Specifically, the connecting component includes: a combination of a bolt, a stud and a nut, a screw, etc.

[0104] As Figure 5 、 Figure 9 and Figure 10 shown, in some embodiments of the present invention, optionally, the shock-absorbing component 130 includes: a cushion block 132, which is inserted through the installation hole 1104, and the through hole 1302 is located in the cushion block 132; wherein, the peripheral side of the cushion block 132 includes a first rib 1322 and a second rib 1324. The first rib 1322 is located inside the volute 110, and the second rib 1324 is located outside the volute 110. The first rib 1322 and the second rib 1324 clamp the volute 110.

[0105] In this embodiment, the fixing part extends outwards relative to the motor 120. The shock-absorbing component 130 includes a cushion block 132. The peripheral side of the 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.

[0106] During the assembly process, first press the spacer block 132 into the mounting hole 1104 opened at the bottom of the housing. The first rib 1322 is located inside the housing, and the second rib 1324 is located outside the housing. The first rib 1322 and the second rib 1324 jointly clamp the housing, thereby realizing the preliminary positioning of the spacer block 132 and preventing the spacer block 132 from falling off from the mounting hole 1104.

[0107] After the preliminary positioning of the spacer block 132 is completed, insert the fixing part into the through hole 1302 on the spacer block 132 to complete the preliminary positioning of the motor 120. In this case, the spacer block 132 is clamped by the inner surface of the mounting hole 1104 and the outer surface of the fixing part, and the axial positioning and radial positioning of the spacer block 132 are realized in cooperation with the aforementioned first rib 1322 and second rib 1324.

[0108] Among them, in the axial direction of the motor 120, the first rib 1322 can absorb the axial vibration impact between the motor 120 and the inner surface of the volute 110. Correspondingly, in the second direction, the spacer block 132 embedded in the mounting hole 1104 can absorb the lateral vibration impact between the hole wall of the mounting hole 1104 and the fixing part.

[0109] After inserting the fixing part into the through hole 1302, screw the connecting part into the screw hole in the fixing part to complete the assembly.

[0110] After the assembly is completed, the second rib 1324 is clamped between the head of the connecting part and the outer surface of the housing, and the first rib 1322 is clamped between the lower surface of the motor 120 and the inner surface of the housing. Thus, on the one hand, the first rib 1322 and the second rib 1324 absorb the impact force transmitted from the motor 120 to the housing to reduce the working noise, and on the other hand, the first rib 1322 and the second rib 1324 realize the sealing on both the inside and outside.

[0111] It can be seen that by setting the spacer block 132 embedded in the mounting hole 1104 and the fixing part inserted into the spacer 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 part to ensure that the motor 120 and the shock-absorbing 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 shock-absorbing component 130 and enhancing the structural stability of the range hood assembly 100.

[0112] As Figure 11 and Figure 12 shown, in some embodiments of the present invention, optionally, one end of the through hole 1302 facing the outside of the volute 110 is the outlet 1304, and one end of the through hole 1302 facing the inside of the volute 110 is the inlet 1306; the aperture of the inlet 1306 is larger than the aperture of the outlet 1304.

[0113] In this embodiment, the through hole 1302 includes an inlet 1306 and an outlet 1304, where the inlet 1306 faces the inner side of the volute 110, the outlet 1304 faces the outer side of the volute 110, the fixing portion on the motor 120 is inserted into the through hole 1302 from the inlet 1306, and the connecting component is inserted into the through hole 1302 from the outlet 1304 and finally screwed into the threaded hole on the fixing portion.

[0114] On this basis, the aperture of the inlet 1306 is larger than that of the outlet 1304, and in the direction from the inlet 1306 to the outlet 1304, the aperture of the through hole 1302 gradually decreases.

[0115] By providing the inlet 1306 with a larger aperture, the difficulty of inserting the fixing portion on the motor 120 into the through hole 1302 can be reduced, thereby reducing the assembly difficulty of the motor 120. By providing the outlet 1304 with a smaller aperture and the through hole 1302 with a gradually decreasing aperture, the fixing portion can squeeze the cushion block 132 during the process of inserting into the through hole 1302, so that the cushion block 132 can effectively fill the space between the fixing portion and the hole wall of the mounting hole 1104. Thus, on the one hand, the shock absorption effect of the cushion block 132 in the second direction is improved, and on the other hand, the sealing effect of the cushion block 132 between the mounting hole 1104 and the fixing portion is improved.

[0116] As Figure 11 and Figure 12 shown, in some embodiments of the present utility model, optionally, the outer diameter of the shock absorption component 130 is D0; the aperture of the outlet 1304 is D1, and D0 and D1 satisfy the relationship: 0.405 ≤ D1÷D0 ≤ 0.477; the aperture of the inlet 1306 is D2, and D0 and D2 satisfy the relationship: 0.481 ≤ D2÷D0 ≤ 0.543.

[0117] In this embodiment, the sizes of the inlet 1306 and the outlet 1304 of the through hole 1302 are defined.

[0118] D0 is the outer diameter of the shock absorption component 130, and D0 is the input condition. Specifically, D0 can be selected as 16 mm.

[0119] D1 is the aperture of the outlet 1304, 0.405 ≤ D1÷D0 ≤ 0.477. Specifically, D1÷D0 = 0.45 can be selected, that is, D1 = 7.2 mm.

[0120] D2 is the aperture of the inlet 1306, 0.481 ≤ D2÷D0 ≤ 0.543. Specifically, D2÷D0 = 0.49 can be selected, that is, D2 = 7.9 mm.

[0121] By defining the above size relationship, the dimensional matching degree between the through hole 1302 and the fixing part on the motor 120 can be improved, thereby enhancing the shock absorption effect of the cushion block 132 in the second direction.

[0122] As Figure 11 and Figure 12 shown, in some embodiments of the present invention, optionally, the thickness of the second rib 1324 is greater than or equal to the thickness of the first rib 1322.

[0123] In this embodiment, the axial direction of the through hole 1302 corresponds to the height direction of the shock-absorbing component 130.

[0124] On this basis, the thickness of the second rib 1324 is greater than or equal to the thickness of the first rib 1322, and the second rib 1324 is clamped outside the mounting hole 1104. By providing the second rib 1324 with a thickness greater than or equal to that of the first rib 1322, the second rib 1324 can withstand greater impacts and bear greater stresses, thereby enhancing the limiting reliability of the second rib 1324 on the cushion block 132, preventing the first rib 1322 and the cushion block 132 from being misaligned towards the inside of the volute 110, and further enhancing the absorption effect of the first rib 1322 and the cushion block 132 on vibration shocks.

[0125] As Figure 11 and Figure 12 shown, in some embodiments of the present invention, optionally, the outer diameter of the shock-absorbing component 130 is D0; the thickness of the shock-absorbing component 130 is H0, and D0 and H0 satisfy the relationship: 0.59 ≤ H0÷D0 ≤ 0.72; the thickness of the first rib 1322 is H1, and D0 and H1 satisfy the relationship: 0.17 ≤ H1÷D0 ≤ 0.21; the thickness of the second rib 1324 is H2, and D0 and H2 satisfy the relationship: 0.28 ≤ H2÷D0 ≤ 0.34.

[0126] In this embodiment, the thicknesses of the first rib 1322 and the second rib 1324 are defined.

[0127] D0 is the outer diameter of the shock-absorbing component 130, and D0 is an input condition. Specifically, D0 can be selected as 16 mm.

[0128] H0 is the thickness of the shock-absorbing component 130, 0.59 ≤ H0÷D0 ≤ 0.72. Specifically, H0÷D0 = 0.66 can be selected, that is, H0 = 10.5 mm.

[0129] H1 is the thickness of the first rib 1322, 0.17 ≤ H1÷D0 ≤ 0.21. Specifically, H1÷D0 = 0.19 can be selected, that is, H1 = 3 mm.

[0130] H2 is the thickness of the second convex rib 1324, 0.28 ≤ H2÷D0 ≤ 0.34, specifically, H2÷D0 = 0.31 can be selected, that is, H2 = 5 mm;

[0131] As Figure 13 , Figure 14 and Figure 15 shown, according to the above design parameters and matching relationships, the shape and size of the shock-absorbing component 130 are designed. It can not only isolate the vibration in the axial direction of the motor 120, but also isolate the vibration in the second direction of the motor 120, thereby reducing the vibration acceleration of the range hood assembly 100 and the integrated stove 200 by 36% and reducing the noise by 2.2 dB. Furthermore, the technical effects of improving the working reliability of the range hood assembly 100 and enhancing the user experience are achieved.

[0132] As Figure 6 and Figure 8 shown, in some embodiments of the present invention, optionally, the number of shock-absorbing components 130 is N, and N shock-absorbing components 130 are evenly distributed around the mounting hole 1104, where N is an integer greater than or equal to 3.

[0133] In this embodiment, N shock-absorbing components 130 are provided between the motor 120 and the volute 110, and N shock-absorbing components 130 are evenly distributed around the mounting hole 1104 around the mounting hole 1104, that is, the angle between adjacent two mounting holes 1104 is the same.

[0134] Among them, N is an integer greater than or equal to 3. Specifically, N can be selected as 3, and the three mounting holes 1104 are distributed at an angular interval of 120°.

[0135] By providing a plurality of shock-absorbing components 130, the vibration impact generated by the motor 120 on the volute 110 can be shared, and the load on each shock-absorbing component 130 can be reduced. Thus, on the one hand, the shock absorption effect of the shock-absorbing component 130 on the impact is improved, and on the other hand, the probability of the shock-absorbing component 130 being damaged due to the impact is reduced.

[0136] By evenly distributing a plurality of shock-absorbing components 130 around the mounting hole 1104, the force uniformity of the plurality of shock-absorbing components 130 can be improved, avoiding damage to a certain shock-absorbing component 130 due to uneven force, and further reducing the failure rate of the shock-absorbing component 130.

[0137] As Figure 3 and Figure 4 shown, in some embodiments of the present invention, optionally, the range hood assembly 100 further includes: an impeller 140, the impeller 140 is disposed in the volute 110, and the impeller 140 is connected to the motor 120.

[0138] In this embodiment, the range hood assembly 100 further includes an impeller 140. The power output end of the motor 120 is connected to the impeller 140. The motor 120 is configured to drive the impeller 140 to rotate, so as to draw cooking fumes into the volute 110 through the impeller 140 from the smoke inlet, and discharge the cooking fumes from the volute 110 through the outlet 1304 after pressurization and acceleration, thereby realizing the suction and centralized discharge of cooking fumes.

[0139] As Figure 1 , Figure 2 and Figure 3 shown, an embodiment of the present utility model provides an integrated range hood 200, which includes: a main body 210, and a flue 2102 is included in the main body 210; the range hood assembly 100 in any of the above embodiments, the volute 110 is connected to the main body 210, and the cavity 1102 is communicated with the flue 2102.

[0140] Figure 3 The arrow a in the figure shows the flow direction of the cooking fumes.

[0141] In this embodiment, an integrated range hood 200 provided with the range hood assembly 100 in any of the above embodiments is defined. Therefore, the integrated range hood 200 has the advantages of the range hood assembly 100 in any of the above embodiments, and can achieve the technical effects that the range hood assembly 100 in any of the above embodiments can achieve. To avoid repetition, it will not be elaborated here.

[0142] On this basis, the integrated range hood 200 includes a main body 210, and a flue 2102 is formed in the main body 210. The integrated range hood 200 can draw cooking fumes through the flue 2102 to realize the collection of cooking fumes and avoid the diffusion of cooking fumes everywhere. An air inlet is opened at the top of the main body 210, and the air inlet is communicated with the flue 2102. A grille 240 is embedded inside the air inlet to block foreign objects through the grille 240.

[0143] Among them, the integrated range hood 200 further includes an oil-grease separation component 220 and a filtering component 230.

[0144] The oil-grease separation component 220 is arranged in the flue 2102, and the oil-grease separation component 220 is arranged opposite to the air inlet on the flue 2102. After the cooking fumes flow into the air inlet, they need 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 cooking fumes, complete the pre-stage oil-water separation of the cooking fumes, avoid the cooking fumes carrying oil and water into the range hood assembly 100, thereby on the one hand protecting the range hood assembly 100 from being polluted by oil and water and extending the service life of the integrated range hood 200, on the other hand avoiding the generation of peculiar smell of the oil and water accumulated in the flue 2102, and on the third hand avoiding the secondary pollution of the environment by the cooking fumes processed by the integrated range hood 200.

[0145] The filtering component 230 is installed in the flue 2102. The cooking fume flowing in the flue 2102 needs to pass through the filtering component 230, so that the filtering component 230 filters the cooking fume through the filtering parts, thereby reducing the peculiar smell of the cooking fume, avoiding the secondary pollution of the environment by the cooking fume, and further achieving the technical effects of improving the reliability of the integrated range hood 200 and enhancing the user experience.
