Description

Technical Field

[0001] The present invention relates to the technical field of kitchen appliances, and particularly to a range hood. Background Art

[0002] The kitchen is closely related to everyone's life and is a place for cooking delicious food. In the kitchen, a range hood has become an essential appliance. The range hood can be installed above the cooker and is used to suck the cooking fumes generated during cooking, so as to keep the kitchen air fresh. Generally, the range hood includes a housing and a blower. The volute of the blower is fixed to the housing through a bracket. When the motor inside the blower works, it will cause the blower to resonate. The vibration of the blower will ultimately be transmitted to the housing through the bracket, causing the whole range hood to resonate and generating a relatively large noise when the range hood is working. Summary of the Invention

[0003] Based on this, it is necessary to provide a range hood in view of the problem of relatively large noise generated when the traditional range hood works.

[0004] A range hood, comprising:

[0005] A housing, the housing includes an intersecting top plate and side plates, and an accommodation cavity is formed by enclosing between the top plate and the side plates;

[0006] A blower, the blower is arranged in the accommodation cavity and fixedly connected to the top plate;

[0007] A fixing device, the fixing device includes a first connecting member and a second connecting member, one of the first connecting member and the second connecting member is mated with the side plate, and the other of the first connecting member and the second connecting member is mated with the blower;

[0008] Wherein, the fixing device has a locked state in which the first connecting member and the second connecting member are fixedly connected to each other, and an unlocked state in which the first connecting member and the second connecting member are separated from each other.

[0009] During the transportation of the above-mentioned range hood, the fixing device is switched to the locked state, and the first connecting member and the second connecting member are fixedly connected by using the fixing device, so that the fan is fixedly connected to the side plate of the housing. In this way, the fan is fixedly connected to both the top plate and the side plate of the housing, with more support points and support forces, preventing the fan from being deformed or detached due to too little support during transportation. When installing the range hood after transportation, the fixing device is switched to the unlocked state, separating the first connecting member from the second connecting member, and then separating the fan from the side wall of the housing, so that vibration is not transmitted between the two, which is equivalent to suspending the fan. In this way, when the range hood is working, it prevents the vibration of the fan from being directly transmitted to the side wall of the housing, reducing the vibration received by the housing, and further reducing the vibration of the whole range hood and the noise generated during the operation of the range hood, improving the user experience. In this way, not only can the noise generated during the operation of the range hood be reduced, but also the deformation and detachment of the fan during the transportation of the range hood can be prevented.

[0010] In one embodiment, the fixing device includes a locking assembly. In the locked state, the locking assembly fixedly connects the first connecting member and the second connecting member; in the unlocked state, the locking assembly is separated from the first connecting member and the second connecting member.

[0012] In one embodiment, in the unlocked state, the first clamp and the second clamp are separated from each other and are both separated from the first connecting member and the second connecting member.

[0013] In one embodiment, in the locked state, the first clamp and the second clamp are docked and enclose a first accommodating cavity and a second accommodating cavity, and at least a part of the first connecting member is sleeved in the first accommodating cavity, and at least a part of the second connecting member is sleeved in the second accommodating cavity.

[0014] In one embodiment, the second connecting member has a limiting hole, and a limiting boss is formed after the first clamp and the second clamp are docked, and the limiting boss is sleeved in the limiting hole.

[0015] In one embodiment, the first connecting member is arranged to extend in a long strip shape and is engaged with the side plate. The fixing device further includes a limiting assembly, and the limiting assembly includes a first limiting member and a second limiting member. The first limiting member and the second limiting member are arranged on the first connecting member at intervals along the extending direction of the first connecting member.

[0016] In the locked state, at least part of the first clamp and at least part of the second clamp are sleeved between the first limiting member and the second limiting member.

[0017] In one embodiment, the fixing device includes a fastener, and the fastener fixedly connects the mutually butted first clamp and the second clamp.

[0018] In one embodiment, a through hole is formed in one of the first clamp and the second clamp, and a connection hole communicating with the through hole is formed in the other of the first clamp and the second clamp. The fastener passes through the through hole and is threadedly connected to the hole wall of the connection hole.

[0033] Refer to Figure 1 , in an embodiment of the present invention, an oil fume extractor 100 is provided, which includes a housing 10 and a fan 30. The fan 30 is disposed in the housing 10 and is used to form a negative pressure for sucking oil fume, so as to suck the oil fume generated during cooking in the kitchen to the outside. The housing 10 includes a top plate 12 and a side plate 14 that are intersectingly connected. A receiving cavity is formed by enclosing between the top plate 12 and the side plate 14. The fan 30 is disposed in the receiving cavity and is fixedly connected to the top plate 12, thus fixing the fan 30 on the top plate 12 of the housing 10.

[0034] Refer to Figures 2 - 5 , the oil fume extractor 100 further includes a fixing device 50. The fixing device 50 includes a first connecting member 52 and a second connecting member 54. One of the first connecting member 52 and the second connecting member 54 is engaged with the side plate 14, and the other of the first connecting member 52 and the second connecting member 54 is engaged with the fan 30; wherein, the fixing device 50 has a locked state in which the first connecting member 52 and the second connecting member 54 are fixedly connected to each other, and an unlocked state in which the first connecting member 52 and the second connecting member 54 are separated from each other.

[0035] In this way, during the transportation of the range hood 100, the fixing device 50 is switched to the locked state, and the first connecting member 52 and the second connecting member 54 are fixedly connected by using the fixing device 50. Further, the blower 30 is fixedly connected to the side plate 14 of the housing 10. In this way, the blower 30 is fixedly connected to both the top plate 12 and the side plate 14 of the housing 10, having more support points and support forces, preventing the blower 30 from being deformed or detached due to too little support during transportation. When installing the range hood 100 after transportation, the fixing device 50 is switched to the unlocked state, so that the first connecting member 52 and the second connecting member 54 are separated, and further the blower 30 is separated from the side wall of the housing 10, and no vibration is transmitted between the two, which is equivalent to suspending the blower 30. In this way, when the range hood 100 is working, it prevents the vibration of the blower 30 from being directly transmitted to the side wall of the housing 10, reduces the vibration received by the housing 10, and further reduces the vibration of the whole range hood 100, reduces the noise generated when the range hood 100 is working, and improves the user experience. In this way, not only can the noise generated when the range hood 100 is working be reduced, but also the range hood 100 can be prevented from deforming and detaching the blower 30 during transportation.

[0036] In some embodiments, the fixing device 50 includes a locking assembly 55. In the locked state, the locking assembly 55 fixedly connects the first connecting member 52 and the second connecting member 54 to fixedly connect the blower 30 and the side plate 14 of the housing 10, preventing too few fixing points of the blower 30 during the transportation of the range hood 100 and preventing the blower 30 from being deformed or detached. In the unlocked state, the locking assembly 55 is separated from the first connecting member 52 and the second connecting member 54, and further the first connecting member 52 and the second connecting member 54 are separated. In this way, when assembling the range hood 100, the locking assembly 55 can be disassembled, so that the first connecting member 52 and the second connecting member 54 are no longer fixedly connected, and further the blower 30 is suspended, reducing the vibration transmitted from the blower 30 to the housing 10, and further reducing the noise generated when the range hood 100 is working.

[0037] Refer to Figures 3 - 5, Further, the locking assembly 55 includes a first fixture 551 and a second fixture 553. In the locked state, the first fixture 551 is sleeved on the same side of the first connecting member 52 and the second connecting member 54, the second fixture 553 is sleeved on the other same side of the first connecting member 52 and the second connecting member 54, and the first fixture 551 and the second fixture 553 are butted against each other and fixedly connected. During the assembly process, the first fixture 551 is sleeved from one side so that the first fixture 551 is sleeved on the first connecting member 52 and the second connecting member 54, then the second fixture 553 is sleeved from the opposite side so that the second fixture 553 is also sleeved on the first connecting member 52 and the second connecting member 54, and finally the first fixture 551 and the second fixture 553 are butted against each other and fixedly connected to each other, thereby fixedly connecting the first connecting member 52 and the second connecting member 54 through the fixedly connected first fixture 551 and second fixture 553.

[0038] In the unlocked state, the first fixture 551 and the second fixture 553 are separated from each other and are both separated from the first connecting member 52 and the second connecting member 54. Equivalently, when switching the state of the locking assembly 55, the first fixture 551 and the second fixture 553 can be separated from each other, and the first fixture 551 is detached from the first connecting member 52 and the second connecting member 54, and the second fixture 553 is also detached from the first connecting member and the second connecting member 54, so as to switch the locking assembly 55 from the locked state to the unlocked state, reducing the connection points between the fan 30 and the housing 10 and reducing the vibration transmission and the noise generated during operation.

[0039] Refer to Figure 3 and Figure 5 , In some embodiments, in the locked state, the first fixture 551 and the second fixture 553 are butted against each other and enclose to form a first accommodating cavity 555 and a second accommodating cavity 556, and at least a part of the first connecting member 52 is sleeved in the first accommodating cavity 555, and at least a part of the second connecting member 54 is sleeved in the second accommodating cavity 556. In this way, in the locked state, after the first fixture 551 and the second fixture 553 are butted against each other, a first accommodating cavity 555 and a second accommodating cavity 556 are formed between the first fixture 551 and the second fixture 553, so that the first fixture 551 and the second fixture 553 are integrally sleeved on the first connecting member 52 and the second connecting member 54, thereby fixedly connecting the first connecting member 52 and the second connection. In the unlocked state, after the first fixture 551 and the second fixture 553 are separated from each other, the first accommodating cavity 555 and the second accommodating cavity 556 will disappear, and the first fixture 551 and the second fixture 553 no longer cooperate to fixedly connect the first connecting member 52 and the second connecting member 54, allowing the connection points between the first connecting member 52 and the second connecting member 54 to disappear.

[0040] Refer to Figure 2, in some embodiments, the first connecting member 52 is arranged to extend in a long strip shape and is engaged with the side plate 14. For example, the first connecting member 52 is welded to the side plate 14 or connected by screws. The fixing device 50 further includes a limiting assembly, and the limiting assembly includes a first limiting member 571 and a second limiting member 573. The first limiting member 571 and the second limiting member 573 are arranged on the first connecting member 52 along the extending direction of the first connecting member 52; in the locked state, at least part of the first clamp 551 and at least part of the second clamp 553 are both sleeved between the first limiting member 571 and the second limiting member 573. In this way, the first clamp 551 and the second clamp 553 can be limited in the extending direction of the first connecting member 52 by the first limiting member 571 and the second limiting member 573, which is convenient for the assembly and alignment of the first clamp 551 and the second clamp 553.

[0041] Refer to Figures 4 - 5 , in some embodiments, the second connecting member 54 has a limiting hole 541. After the first clamp 551 and the second clamp 553 are butted against each other, a limiting boss 554 is formed. The limiting boss 554 is sleeved in the limiting hole 541. In this way, the first clamp 551 and the second clamp 553 can be further limited by the sleeving of the limiting boss 554 and the second connecting member 54, and the first clamp 551 and the second clamp 553 can be conveniently assembled in place through limiting during the assembly process.

[0042] In some embodiments, the fixing device 50 includes a fastener 58, and the fastener 58 fixedly connects the butted first clamp 551 and second clamp 553. In this way, the first clamp 551 and the second clamp 553 are detachably fixedly connected by the fastener 58, and the fastener 58 can be disassembled when it is necessary to separate the first clamp 551 and the second clamp 553.

[0043] Specifically, a through hole is formed in one of the first clamp 551 and the second clamp 553, and a connecting hole communicating with the through hole is formed in the other of the first clamp 551 and the second clamp 553. The fastener 58 passes through the through hole and is threadedly connected to the hole wall of the connecting hole. In this way, a through hole and a connecting hole are respectively formed in the first clamp 551 and the second clamp 553 to cooperate with the fastener 58 for connection, so as to fixedly connect the first clamp 551 and the second clamp 553 by the fastener 58. It can be understood that the hole wall of the through hole can also be threadedly connected to the fastener 58, which is not limited herein.

[0044] Refer to Figures 3 - 5, in some embodiments, the fastener 58 is located on the side of the first connecting member 52 away from the second connecting member 54. The fixing device 50 further includes an auxiliary assembly 59. The auxiliary assembly 59 is provided at one end of the locking assembly 55 away from the fastener 58, that is, on the side of the second connecting member 54 away from the first connecting member 52, and is used to lock and then release the first clamp 551 and the second clamp 553. Equivalently, the fastener 58 and the locking assembly 55 are respectively arranged on both sides where the first connecting member 52 and the second connecting member 54 are located, and two fixed connection points are provided for the first clamp 551 and the second clamp 553, improving the reliability of the fixed connection.

[0045] Refer to Figure 2 , specifically, the auxiliary assembly 59 includes a buckle 591 and a protrusion 593. The buckle 591 is provided on the first clamp 551, and the protrusion 593 is provided on the second clamp 553. The buckle 591 and the protrusion 593 can be engaged with or separated from each other. In this way, the buckle 591 and the protrusion 593 are respectively arranged on the first clamp 551 and the second clamp 553. When the first clamp 551 and the second clamp 553 are butted against each other, the buckle 591 and the protrusion 593 can be engaged to lock the first clamp 551 and the second clamp 553, and the locking assembly 55 is switched to the locked state. When the first clamp 551 and the second clamp 553 need to be separated, the separation of the buckle 591 and the protrusion 593 allows the first clamp 551 and the second clamp 553 to be separated, and the locking assembly 55 is switched to the unlocked state.

[0046] The above-mentioned range hood 100 includes a fixing device 50. During the transportation of the range hood 100, the blower 30 and the side wall of the housing 10 are fixed by the fixing device 50, providing more support points for the blower 30 to prevent the blower 30 from being deformed or falling off after being impacted during transportation. When assembling the range hood 100 after transportation is completed, the fixing device 50 can be switched to the unlocked state, so that the fixing device 50 no longer fixedly connects the blower 30 and the side wall of the housing 10, making the blower 30 and the side wall of the housing 10 independent of each other. In this way, the vibration generated when the blower 30 works will not be directly transmitted to the side wall of the housing 10, reducing the vibration generated by the housing 10, and further reducing the vibration and noise of the whole range hood 100 during operation, improving the user experience.

[0047] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered to be within the scope described in this specification.

[0048] The above-described embodiments merely represent several implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the invention patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all fall within the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the appended claims.
