Description

FIELD

[0001] The invention relates to the technical field of household electrical appliances, and more particularly, to an electrical appliance assembly.BACKGROUND

[0002] In the related art, a range hood generally includes a housing, and a panel disposed at the housing. The panel generally has a size larger than the area of the housing. The range hood may be embedded in a bearing plate for mounting. The bearing plate generally has a mounting hole. During mounting of the range hood, to provide an operation space for facilitating tight mounting of the housing at the bearing plate using fasteners such as a screw, normally the panel is detached from the housing, and then is mounted at the housing after the housing is mounted at the mounting hole of the bearing plate, which results in inconvenient mounting operations and a low assembly and disassembly efficiency.SUMMARY

[0003] The invention provides an electrical appliance assembly, which at least solves technical problems of inconvenient mounting operations and a low assembly and disassembly efficiency of a range hood.

[0004] The invention provides an electrical appliance assembly. The electrical appliance assembly includes a range hood and an assembly and disassembly mechanism. The range hood includes a housing passing through a bearing plate. The bearing plate has a mounting hole. The assembly and disassembly mechanism includes a snap-fitting base mounted at the housing and a snap-fitting member movably disposed at the snap-fitting base. The snap-fitting member is configured to abut against a wall of the mounting hole when the housing passes through the mounting hole to move relative to the snap-fitting base and pass through the mounting hole, and the snap-fitting member is further configured to abut against a bearing surface of the bearing plate after the snap-fitting member passes through the mounting hole.

[0005] In the electrical appliance assembly according to embodiments of the invention, when the range hood is pushed to move from bottom to top to be mounted at the bearing plate, the snap-fitting member moves under an action of the mounting hole, in such a manner that the range hood can pass through the mounting hole, and the snap-fitting member can pass through the mounting hole and the snap-fitting member is further configured to abut against the bearing surface of the bearing plate after the snap-fitting member passes through the mounting hole. In this way, the range hood can be mounted without screws, which leads to a convenient mounting process and a high assembly and disassembly efficiency.

[0006] Optionally, the snap-fitting base may have an avoidance space for the housing mounted at the range hood.

[0007] Optionally, the snap-fitting member may be movably disposed at the snap-fitting base and may include a support and a snap-fitting portion connected to the support.

[0008] Optionally, the snap-fitting portion may be movable between a first position and a second position and may be configured to move from the first position to the second position when the snap-fitting portion abuts against the wall of the mounting hole.

[0009] Optionally, the snap-fitting portion may be located outside the avoidance space when the snap-fitting portion is located at the first position, and at least partially located in the avoidance space when the snap-fitting portion is located at the second position.

[0010] Optionally, the snap-fitting portion may be configured to abut against the bearing surface of the bearing plate when the snap-fitting portion is located at the first position.

[0011] Optionally, the assembly and disassembly mechanism may further include an elastic member connected to the snap-fitting base and the snap-fitting member.

[0012] Optionally, the elastic member may be configured to apply an elastic force to the snap-fitting member after the snap-fitting member passes through the mounting hole to restore the snap-fitting portion to the first position from the second position.

[0013] In this way, the snap-fitting portion is configured to move from the first position to the second position by an external force, in such a manner that when the range hood is pushed to move from bottom to top to be mounted at the bearing plate, the snap-fitting portion retracts into the avoidance space under an action of the bearing plate to enable the range hood to pass through the bearing plate. In addition, after the range hood passes through the bearing plate, the elastic member restores the snap-fitting portion to the first position from the second position. That is, the snap-fitting portion is located outside the avoidance space to enable the snap-fitting portion to abut against the bearing surface of the bearing plate, which leads to the convenient mounting process and the high assembly and disassembly efficiency.

[0014] Optionally, the snap-fitting base may include two first support plates opposite to each other and a first connection plate connected to the two first support plates.

[0015] Optionally, the avoidance space may be defined by the first connection plate and the two first support plates.

[0016] In this way, the snap-fitting base has a simple structure, and the avoidance space is easy to form, which can reduce costs of the snap-fitting base.

[0017] Optionally, the snap-fitting base may further include a stopping piece connected to an edge of each of the two first support plates.

[0018] Optionally, the stopping piece may be spaced apart from the first connection plate.

[0019] Optionally, the snap-fitting member may be position-limited between the first connection plate and the stopping piece.

[0020] In this way, the stopping piece, the first support plate, and the first connection plate engage with each other, which can limit a position of the snap-fitting member. Therefore, the snap-fitting member and the snap-fitting base are mounted to form an entirety, which is beneficial to improving the assembly and disassembly efficiency of the range hood by the assembly and disassembly mechanism.

[0021] Optionally, the snap-fitting base may further include a position-limiting piece connected to an edge of the first connection plate.

[0022] Optionally, the position-limiting piece may extend away from the avoidance space from the first connection plate.

[0023] Optionally, a slide groove may be formed between the position-limiting piece and the stopping piece.

[0024] Optionally, the snap-fitting member may be slidable in the slide groove.

[0025] Optionally, the snap-fitting member may be configured to pivot about an edge of the position-limiting piece connected to the first connection plate when an external force is applied to the snap-fitting portion.

[0026] In this way, the snap-fitting member is slidable in the slide groove between the position-limiting piece and the stopping piece, in such a manner that the position of the snap-fitting member can be adjusted to enhance an abutting force exerted by the snap-fitting portion against the bearing surface. In addition, the position-limiting piece enlarges a contact area between the snap-fitting member and the snap-fitting base, which is beneficial to limiting the position of the snap-fitting member, making a connection between the snap-fitting member and the snap-fitting base more stable. Further, since the snap-fitting member is configured to pivot about the edge of the position-limiting piece connected to the first connection plate, the snap-fitting portion can more easily move into the avoidance space.

[0027] Optionally, the snap-fitting base may further include a mounting piece connected to an end of each of the two first support plates away from the first connection plate.

[0028] Optionally, the mounting piece may extend away from the avoidance space from the first support plate and is connected to the housing of the range hood.

[0029] In this way, the mounting piece enables the assembly and disassembly mechanism to be easily mounted at the housing.

[0030] Optionally, the snap-fitting portion may have a bottom surface and a guide surface.

[0031] Optionally, the guide surface may extend downwards from the support and extends away from the support.

[0032] Optionally, the bottom surface may be configured to abut against the bearing surface.

[0033] Optionally, the guide surface may be configured to enable the snap-fitting portion to move from the first position towards the second position when the guide surface abuts against the wall of the mounting hole.

[0034] In this way, the guide surface extends downwards from the support and extends away from the support, in such a manner that the snap-fitting portion can retract into the avoidance space under the action of the bearing plate in a process of mounting the range hood from bottom to top, which is beneficial to improving a mounting efficiency of the range hood.

[0035] Optionally, the support may include a second support plate and a second connection plate bent towards the second support plate.

[0036] Optionally, the second support plate may be movable relative to the two first support plates.

[0037] Optionally, the second connection plate may be arranged opposite to the first connection plate.

[0038] Optionally, the snap-fitting portion may be disposed at a side of the second support plate away from the second connection plate.

[0039] Optionally, the first connection plate and the second connection plate may be connected to each other by the elastic member.

[0040] In this way, the second connection plate is arranged opposite to the first connection plate, which enables the elastic member to easily connect the snap-fitting base and the snap-fitting member. In addition, the second support plate can provide support for the snap-fitting portion, which enables the snap-fitting member to move relative to the snap-fitting base through the second support plate.

[0041] Optionally, the assembly and disassembly mechanism may include a screw and a nut.

[0042] Optionally, the nut may be disposed at the first connection plate.

[0043] Optionally, the screw may penetrate the first connection plate and the second connection plate and may be connected to the nut.

[0044] Optionally, the screw may be engaged with the nut to adjust a distance between the first connection plate and the second connection plate.

[0045] In this way, the screw is engaged with the nut to adjust the distance between the first connection plate and the second connection plate, in such a manner that a position of the snap-fitting portion can be adjusted to enable the snap-fitting portion to abut against the bearing surface of the bearing plate more stably.

[0046] Optionally, the second connection plate may have a through hole.

[0047] Optionally, the screw may pass through the through hole.

[0048] Optionally, the through hole may be a waist-type hole.

[0049] Optionally, a length direction of the through hole may be parallel to a thickness direction of the second support plate.

[0050] In this way, the through hole can provide a space for the second connection plate to move with a movement of the snap-fitting portion, which enables the snap-fitting portion to smoothly move between the first position and the second position.

[0051] Optionally, the housing may include a body and a flange extending from the body.

[0052] Optionally, the snap-fitting base may be mounted at the flange.

[0053] Optionally, the snap-fitting portion may extend beyond an edge of the flange away from the body.

[0054] In this way, the snap-fitting portion can effectively abut against the bearing surface of the bearing plate.

[0055] Optionally, the range hood may further include a panel connected to the flange.

[0056] Optionally, an edge of the panel may extend beyond the edge of the flange away from the body.

[0057] Optionally, the panel may be configured to be positioned at a side of the bearing plate away from the bearing surface.

[0058] In this way, when the range hood is mounted through being pushed to move from bottom to top, the panel can always be connected to the housing and be kept under the bearing plate, and the snap-fitting portion can pass over the mounting hole of the bearing plate to abut against the bearing surface of the bearing plate.

However, those of ordinary skill in the art may be aware of applications of other processes and / or the use of other materials.

[0067] As illustrated in FIG. 1 to FIG. 3, the invention discloses an electrical appliance assembly 1000. The electrical appliance assembly 1000 includes a range hood 200 and an assembly and disassembly mechanism 100. The range hood 200 includes a housing 210 passing through a bearing plate 500. The bearing plate 500 has a mounting hole 520. The assembly and disassembly mechanism 100 includes a snap-fitting base 10 mounted at the housing 210 and a snap-fitting member 10 movably disposed at the snap-fitting base 10. The snap-fitting member 20 is configured to abut against a wall of the mounting hole 520 when the housing 210 passing through the mounting hole 520 to move relative to the snap-fitting base 10 and pass through the mounting hole 520, and the snap-fitting member 10 is further configured to abut against a bearing surface 510 of the bearing plate 500 after the snap-fitting member 10 passes through the mounting hole 520.

[0068] In this way, when the range hood 200 is pushed to move from bottom to top to be mounted at the bearing plate 500, the snap-fitting member 20 moves under an action of the mounting hole 520, in such a manner that the range hood 200 can pass through the mounting hole 520, and the snap-fitting member 20 can pass through the mounting hole 520 and then abut against the bearing surface 510 of the bearing plate 500. In this way, the range hood 200 can be mounted without screws, which leads to a convenient mounting process and a high assembly and disassembly efficiency.

[0069] Specifically, the range hood 200 may be an embedded electrical appliance. That is, the range hood 200 may be accommodated in a certain space. The bearing plate 500 is a component for bearing the range hood 200. For example, the bearing plate 500 may be a partition of a cabinet. In this case, the range hood 200 may be housed in the cabinet and mounted at the bearing plate 500, in such a manner that the bearing plate 500 provides support for the entire range hood 200.

[0070] The bearing surface 510 of the bearing plate 500 is an upper surface of the bearing plate 500, in such a manner that the assembly and disassembly mechanism 100 can pass through the mounting hole 520 and then abut against the bearing surface 510, enabling the range hood 200 to be stably mounted at the bearing plate 500.

[0071] As illustrated in FIG. 3 to FIG. 5, in some embodiments, the snap-fitting base 10 has an avoidance space 11 for mounting the housing 210 of the range hood 200. The snap-fitting member 20 is movably disposed at the snap-fitting base 10 and includes a support 21 and a snap-fitting portion 22 connected to the support 21. The snap-fitting portion 22 is movable between a first position and a second position and is configured to move from the first position to the second position when the snap-fitting portion 22 abuts against the wall of the mounting hole 520. The snap-fitting portion 22 is located outside the avoidance space 11 when the snap-fitting portion 22 is located at the first position (as illustrated in FIG. 3) and is at least partially located in the avoidance space 11 when the snap-fitting portion 22 is located at the second position (as illustrated in FIG. 5). The snap-fitting portion 22 is configured to abut against the bearing surface 510 of the bearing plate 500 when the snap-fitting portion 22 is located at the first position. The assembly and disassembly mechanism 100 further includes an elastic member 30 connected to the snap-fitting base 10 and the snap-fitting member 20. The elastic member 30 is configured to apply an elastic force to the snap-fitting member 20 after the snap-fitting member 20 passes through the mounting hole 520 to restore the snap-fitting portion 22 to the first position from the second position.

[0072] In this way, the snap-fitting portion 22 is configured to move from the first position to the second position by an external force, in such a manner that when the range hood 200 is pushed to move from bottom to top to be mounted at the bearing plate 500, the snap-fitting portion 22 retracts into the avoidance space 11 under an action of the bearing plate 500 to enable the range hood 200 to pass through the bearing plate 500. In addition, after the range hood 200 passes through the bearing plate 500, the elastic member 30 restores the snap-fitting portion 22 to the first position from the second position. That is, the snap-fitting portion 22 is located outside the avoidance space 11 to enable the snap-fitting portion 22 to abut against the bearing surface 510 of the bearing plate 500, which leads to the convenient mounting process and the high assembly and disassembly efficiency.

[0073] Specifically, the snap-fitting base 10 is a basic component of the assembly and disassembly mechanism 100. The snap-fitting base 10 can provide a stable base for the snap-fitting base 10 mechanism, in such a manner that components of the snap-fitting base 10 such as the snap-fitting member 20 can be stably mounted at the snap-fitting base 10. Mounting the snap-fitting base 10 at the housing 210 enables the entire assembly and disassembly mechanism 100 to be mounted at the housing 210 of the range hood 200. To provide strength for the snap-fitting base 10, the snap-fitting base 10 may be made of metal.

[0074] The snap-fitting member 20 can undergo sliding, swinging, or other movements relative to the snap-fitting base 10, in such a manner that the snap-fitting portion 22 of the snap-fitting member 20 smoothly passes through the bearing plate 500 and abuts against the bearing surface 510. The support 21 is configured to provide a connection position for the snap-fitting portion 22. The snap-fitting portion 22 extends beyond an edge of the snap-fitting base 10 relative to the snap-fitting base 10, or the snap-fitting portion 22 forms a part of an outermost contour of the assembly and disassembly mechanism 100.

[0075] Since the snap-fitting member 20 is movable relative to the snap-fitting base 10, the snap-fitting portion 22 of the snap-fitting member 20 is movable between the first position and the second position. The snap-fitting portion 22 is located outside the avoidance space 11 when the snap-fitting portion 22 is located at the first position and is at least partially located in the avoidance space 11 when the snap-fitting portion 22 is located at the second position. That is, after the snap-fitting portion 22 moves from the first position to the second position, a size of the assembly and disassembly mechanism 100 decreases in a predetermined direction, in such a manner that the assembly and disassembly mechanism 100 can change its size to smoothly pass through the mounting hole 520 of the bearing plate 500 to be mounted at the bearing surface 510 of the bearing plate 500.

[0076] Since the elastic member 30 is connected to the snap-fitting member 20, the snap-fitting member 20 can be prevented from falling to a lowest position under gravity, preventing the snap-fitting member 20 from failing to move relative to the snap-fitting member 10 and pass through the bearing plate 500 during mounting of the range hood 200. In addition, the elastic member 30 can restore the snap-fitting portion 22 to the first position from the second position, in such a manner that the snap-fitting portion 22 passes over a highest part of the bearing plate 500 and then abuts against the bearing surface 510. The elastic member 30 includes, but is not limited to, a helical spring, a rubber elastic member, and the like. In a case where the elastic member 30 is the helical spring, the elastic member 30 can be maintained in a compression state.

[0077] In an embodiment, when the range hood 200 is mounted from bottom to top, the assembly and disassembly mechanism 100 passes upwards through the mounting hole 520 of the bearing plate 500 along with the housing 210 of the range hood 200. After the mounting hole 520 abuts against the snap-fitting portion 22, the snap-fitting portion 22 moves into the avoidance space 11, which reduces the overall size of the assembly and disassembly mechanism 100. After the snap-fitting portion 22 passes over the mounting hole 520, the snap-fitting portion 22 is located outside the avoidance space 11 under an elastic force of the elastic member 30, in such a manner that the snap-fitting portion 22 can abut against the bearing surface 510 of the bearing plate 500.

[0078] As illustrated in FIG. 4, in some embodiments, the snap-fitting base 10 includes two first support plates 11 opposite to each other and a first connection plate 12 connected to the two first support plates 11. The avoidance space 11 is defined by the first connection plate 12 and the two first support plates 11.

[0079] Specifically, the two first support plates 11 are arranged substantially in parallel. The two first support plates 11 and the first connection plate 12 may be integrally formed through a bending process. The first connection plate 12 is connected to a top end edge of each of the two first support plates 11. Since the two first support plates 11 are spaced apart from each other, a space is formed between the two first support plates 11, in such a manner that the avoidance space 11 is defined by the first connection plate 12 and the two first support plates 11. In this way, the snap-fitting base 10 has a simple structure, and the avoidance space 11 is easy to form, which can reduce costs of the snap-fitting base 10.

[0080] As illustrated in FIG. 4 and FIG. 5, in some embodiments, the snap-fitting base 10 further includes a stopping piece 13 connected to an edge of each of the two first support plates 11. The stopping piece 13 is spaced apart from the first connection plate 12. The snap-fitting member 20 is position-limited between the first connection plate 12 and the stopping piece 13.

[0081] In this way, the stopping piece 13, the first support plate 11, and the first connection plate 12 cooperate with each other, to limit a position of the snap-fitting member 20. Therefore, the snap-fitting member 20 and the snap-fitting base 10 are mounted to form an entirety, which is beneficial to improving the assembly and disassembly efficiency of the range hood 200 by the assembly and disassembly mechanism 100.

[0082] Specifically, each of the two first support plates 11 is provided with one stopping piece 13, which is connected to an edge of each of the two first support plates 11 extending in a height direction of the two first support plates 11. The stopping piece 13 and the first connection plate 12 can limit a movement of the snap-fitting member 20 in a plane perpendicular to the height direction of the first support plate 11, in such a manner that the snap-fitting member 20 moves in the predetermined direction.

[0083] In the embodiments of the invention, two stopping pieces 13 are located at the same height level of the assembly and disassembly mechanism 100. In addition, an opening is formed between the two stopping pieces 13. The snap-fitting member 20 can be mounted into the snap-fitting base 10 through the opening.

[0084] As illustrated in FIG. 3 and FIG. 4, in some embodiments, the snap-fitting base 10 further includes a position-limiting piece 14 connected to an edge of the first connection plate 12. The position-limiting piece 14 extends away from the avoidance space 11 from the first connection plate 12. A slide groove 15 is formed between the position-limiting piece 14 and the stopping piece 13. The snap-fitting member 20 is slidable in the slide groove 15 and is configured to pivot about an edge of the position-limiting piece 14 connected to the first connection plate 12 when an external force is applied to the snap-fitting portion 22.

[0085] In this way, the snap-fitting member 20 is slidable in the slide groove 15 between the position-limiting piece 14 and the stopping piece 13, in such a manner that the position of the snap-fitting member 20 can be adjusted to enhance an abutting force exerted by the snap-fitting portion 22 against the bearing surface 510. In addition, the position-limiting piece 14 enlarges a contact area between the snap-fitting member 20 and the snap-fitting base 10, which is beneficial to limiting the position of the snap-fitting member 20, making a connection between the snap-fitting member 20 and the snap-fitting base 10 more stable. Further, since the snap-fitting member 20 is configured to pivot about the edge of the position-limiting piece 14 connected to the first connection plate 12, the snap-fitting portion 22 can more easily move into the avoidance space 11 when the snap-fitting portion 22 moves between the first position and the second position.

[0086] Specifically, the position-limiting piece 14 extends upwards from the first connection plate 12. A predetermined distance is formed between the position-limiting piece 14 and the stopping piece 13 in a thickness direction of the position-limiting piece 14, in such a manner that the slide groove 15 is formed between the position-limiting piece 14 and the stopping piece 13. Since the position-limiting piece 14 and the stopping piece 13 are arranged in the height direction of the first support plate 11, the slide groove 15 extends in the height direction of the first support plate 11, which enables the snap-fitting member 20 to slide in the height direction of the first support plate 11. Therefore, a position of the snap-fitting member 20 in the height direction of the first support plate 11 is adjusted, which in turn adjusts a distance between the snap-fitting member 20 and a bottom of the snap-fitting base 10. In this way, the abutting force exerted by the snap-fitting portion 22 against the bearing surface 510 of the bearing plate 500 can be adjusted, which is beneficial for the range hood 200 to be stably mounted at the bearing plate 500.

[0087] As illustrated in FIG. 4, in some embodiments, the snap-fitting base 10 further includes a mounting piece 16 connected to an end of each of the two first support plates 11 away from the first connection plate 12. The mounting piece 16 extends away from the avoidance space 11 from the first support plate 11. The mounting piece 16 is connected to the housing 210 of the range hood 200.

[0088] Specifically, the mounting piece 16 is substantially perpendicular to the two first support plates 11. Each of the two first support plates 11 is connected to the mounting piece 16. The mounting piece 16 may have a passage hole 161. The passage hole 161 can enable the snap-fitting base 10 to be mounted at the housing 210 of the range hood 200 by a threaded fastener. In this way, the mounting piece 16 enables the assembly and disassembly mechanism 100 to be easily mounted at the housing 210.

[0089] As illustrated in FIG. 5 and FIG. 6, in some embodiments, the snap-fitting portion 22 has a bottom surface 221 and a guide surface 222. The guide surface 222 extends downwards from the support 21 and extends away from the support 21. The bottom surface 221 is configured to abut against the bearing surface 510. The guide surface 222 is configured to enable the snap-fitting portion 22 to move from the first position towards the second position when the guide surface 222 abuts against the wall of the mounting hole 520.

[0090] In this way, the guide surface 222 extends downwards from the support 21 and extends away from the support 21, in such a manner that the snap-fitting portion 22 can retract into the avoidance space 11 under the action of the bearing plate 500 in a process of mounting the range hood 200 from bottom to top, which is beneficial to improving a mounting efficiency of the range hood 200.

[0091] Specifically, the snap-fitting portion 22 is similar to a triangular sheet. The guide surface 222 may be an inclined surface, in other words, the guide surface 222 may extend obliquely downwards from the support 21. Therefore, when the range hood 200 is mounted from bottom to top, a lower end of the guide surface 222 of the snap-fitting portion 22 is brought into contact with a side wall of the mounting hole 520 of the bearing plate 500 first. As the range hood 200 moves upwards, a part of the guide surface 222 of the snap-fitting portion 22 in contact with the side wall of the mounting hole 520 of the bearing plate 500 transitions from the lower end to an upper end. Since a distance between the guide surface 222 and the avoidance space 11 gradually decreases from the lower end of the guide surface 222 to the upper end of the guide surface 222, the snap-fitting portion 22 can gradually move into the avoidance space 11, in such a manner that the snap-fitting portion 22 can smoothly pass over the mounting hole 520 of the bearing plate 500 to abut against the bearing surface 510 of the bearing plate 500.

[0092] Of course, in other embodiments, the guide surface 222 may also be a curved surface or the like.

[0093] As illustrated in FIG. 4 and FIG. 5, in some embodiments, the support 21 includes a second support plate 211 and a second connection plate 212 bent towards the second support plate 211. The second support plate 211 is movable relative to the two first support plates 11. The second connection plate 212 is arranged opposite to the first connection plate 12. The snap-fitting portion 22 is disposed at a side of the second support plate 211 away from the second connection plate 212. The first connection plate 12 and the second connection plate 212 are connected to each other by the elastic member 30.

[0094] In this way, the second connection plate 212 is arranged opposite to the first connection plate 12, which enables the elastic member 30 to easily connect the snap-fitting base 10 and the snap-fitting member 20. In addition, the second support plate 211 can provide support for the snap-fitting portion 22, which enables the snap-fitting member 20 to move relative to the snap-fitting base 10 through the second support plate 211.

[0095] Specifically, the second support plate 211 and the second connection plate 212 are connected substantially in an "L" shape. The second support plate 211 is disposed in the slide groove 15, in such a manner that the snap-fitting member 20 slides in the slide groove 15 through the second support plate 211. The second connection plate 212 is located at a top side of the second support plate 211. The snap-fitting portion 22 is located at a bottom side of the second support plate 211. The stopping piece 13 is located between the snap-fitting portion 22 and the second connection plate 212.

[0096] As illustrated in FIG. 3 to FIG. 6, in some embodiments, the assembly and disassembly mechanism 100 includes a screw 40 and a nut 50. The nut 50 is disposed at the first connection plate 12. The screw 40 penetrates the first connection plate 12 and the second connection plate 212 and is connected to the nut 50. The screw 40 is engaged with the nut 50 to adjust a distance between the first connection plate 12 and the second connection plate 212.

[0097] In this way, the screw 40 is engaged with the nut 50 to adjust the distance between the first connection plate 12 and the second connection plate 212, in such a manner that a position of the snap-fitting portion 22 can be adjusted to enable the snap-fitting portion 22 to abut against the bearing surface 510 of the bearing plate 500 more stably.

[0098] Specifically, after the assembly and disassembly mechanism 100 passes over the mounting hole 520 of the bearing plate 500, the snap-fitting portion 22 abuts against the bearing surface 510. In this case, the screw 40 is continuously tightened, which enables the snap-fitting portion 22 to further tightly abut against the bearing surface 510. In the embodiments of the invention, the screw 40 passes through the elastic member 30, in such a manner that the assembly and disassembly mechanism 100 can have a more compact structure.

[0099] As illustrated in FIG. 4 and FIG. 5, in some embodiments, the second connection plate 212 has a through hole 213. The screw 40 passes through the through hole 213. The through hole 213 is a waist-type hole. A length direction of the through hole 213 is parallel to a thickness direction of the second support plate 211.

[0100] It should be understood that, since the second connection plate 212 and the snap-fitting portion 22 are respectively located at two sides of the second support plate 211, the second connection plate 212 and the snap-fitting portion 22 move in different directions when the second support plate 211 pivots about the stopping piece 13. Components of a movement direction of the second connection plate 212 are the thickness direction of the second support plate 211 and a height direction of the second support plate 211. Since the screw 40 penetrates the second connection plate 212 and is connected to the nut 50, the screw 40 limits a movement of the second connection plate 212. Therefore, the through hole 213 is configured as a waist-type hole, and the length direction of the through hole 213 is parallel to the thickness direction of the second support plate 211, which enables the through hole 213 to provide a space for the second connection plate 212 to move along with a movement of the snap-fitting portion 22, allowing the snap-fitting portion 22 to move smoothly between the first position and the second position.

[0101] As illustrated in FIG. 7 to FIG. 9, in some embodiments, the housing 210 includes a body 220 and a flange 230 extending from the body 220. The snap-fitting base 10 is mounted at the flange 230. The snap-fitting portion 22 extends beyond an edge of the flange 230 away from the body 220. In this way, the flange 230 may be disposed in or pass over the mounting hole 520 of the bearing plate 500 during the mounting of the range hood 200. Since the snap-fitting portion 22 extends beyond the edge of the flange 230 away from the body 220, the snap-fitting portion 22 can effectively abut against the bearing surface 510 of the bearing plate 500, enabling the entire range hood 200 to abut against and be mounted at the bearing plate 500.

[0102] In some embodiments 240, the range hood 200 further includes a panel 240 connected to the flange 230. An edge of the panel 240 extends beyond the edge of the flange 230 away from the body 220. The panel 240 is configured to be positioned at a side of the bearing plate 500 away from the bearing surface 510.

[0103] In this way, when the range hood 200 is mounted through being pushed to move from bottom to top, the panel 240 can always be connected to the housing 210 and be kept under the bearing plate 500, and the snap-fitting portion 22 can pass over the mounting hole 520 of the bearing plate 500 to abut against the bearing surface 510 of the bearing plate 500. The panel 240 does not need to be disassembled during the mounting of the range hood 200, which facilitates the mounting of the range hood 200.

[0104] In summary, as illustrated in FIG. 3 and FIG. 7 to FIG. 9, in an embodiment, a mounting process of the range hood 200 is as follows. The range hood 200 is pushed into the mounting hole 520 of the bearing plate 500 from bottom to top. In a process of pushing the range hood 200 into the mounting hole 520 of the bearing plate 500, the snap-fitting portion 22 of the assembly and disassembly mechanism 100 is compressed by the wall of the mounting hole 520 and moves into the avoidance space 11, and thus the overall size of the assembly and disassembly mechanism is small. After the snap-fitting portion 22 passes over the mounting hole 520, the snap-fitting portion 22 is located outside the avoidance space 11 under the elastic force of the elastic member 30, in such a manner that the snap-fitting portion 22 can abut against the bearing surface 510 of the bearing plate 500, allowing the range hood 200 to be fixed. To further improve stability of the range hood 200, the screw 40 can be further tightened.

[0105] A disassembly process of the range hood 200 is essentially an inverse of the mounting process of the range hood 200. Specifically, when the range hood 200 is disassembled, the screw 40 can be loosened, and then the snap-fitting portion 22 can be manually pressed into the avoidance space 11 to enable the snap-fitting portion 22 to pass through the mounting hole 520 of the bearing plate 500. In this way, the range hood 200 can be detached from the bearing plate 500 to be quickly disassembled.
