Abstract
Description
Technical Field
[0001] This utility model relates to the field of kitchen appliance technology, and in particular to a range hood. Background Technology
[0002] Range hoods are common kitchen appliances, primarily used to collect and remove cooking fumes, heat, and odors, keeping the kitchen air clean. The smoke collection chamber within the range hood is the core functional area where fumes are generated and drawn into the fan. It functions to gather and concentrate smoke, guide its flow, separate grease, and prevent fumes from overflowing. However, the structure of the smoke collection chamber in existing range hoods is quite complex. It is mainly formed by splicing together multiple sheet metal components (such as back panels, side panels, connecting plates, and air guide plates). Due to the thinness of the sheet metal components, adjacent parts need to be welded together and fasteners used to ensure the overall strength of the smoke collection chamber. Furthermore, grinding is required after welding, resulting in numerous steps and low production efficiency. High labor costs increase the overall cost of the machine. In addition, some components of the drive mechanism of existing range hoods need to protrude through the smoke collection chamber. This requires the creation of clearance holes in the sheet metal components of the smoke collection chamber to allow the drive mechanism components to pass through. Furthermore, mounting holes for LED lights also need to be made in the sheet metal components of the smoke collection chamber. On the basis of relatively thin sheet metal components, the creation of various through holes will lead to a decrease in the overall strength of the smoke collection chamber. In addition, the sealed space in the existing smoke collection chamber for installing functional modules and drive mechanisms is small. This sealed space is mainly formed by the air guide plate and side plate, which limits the number of functional modules that can be added, which is not conducive to the expansion of the range hood's functions. Utility Model Content
[0003] The present invention aims to solve the technical problems existing in the prior art and provide a range hood with high overall strength of the smoke collection chamber, high production efficiency and low cost.
[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution:
[0005] The present invention discloses a range hood comprising a smoke collection chamber assembly, the smoke collection chamber assembly including a back plate and side plates respectively connected to both sides of the back plate, the side plates being detachably connected to the back plate by fasteners; the smoke collection chamber assembly further includes at least one reinforcing member, the reinforcing member being connected to the back plate, the corresponding side plate, and the corresponding air guide plate, the reinforcing member, the back plate, the side plates, and the air guide plate forming a sealed space for installing functional modules and / or drive mechanisms; the reinforcing member is provided with LED light mounting holes and / or drive mechanism clearance holes.
[0006] The range hood of this utility model, by adding reinforcing members, connects them to the back panel, the corresponding side panels, and the corresponding air guide plate, respectively. These reinforcing members securely connect the back panel, side panels, and air guide plate, enhancing their strength. The cooperation between the fasteners and the reinforcing members improves the overall structural strength of the smoke collection chamber. Since welding and grinding processes are eliminated, the processing difficulty of the smoke collection chamber is reduced, improving the production efficiency of the range hood and lowering production costs. Simultaneously, LED light mounting holes and / or drive mechanisms are provided on the reinforcing members. The avoidance holes reduce the number of through holes to be made on the side plates, air guide plates, or back plates, further improving the overall structural strength of the smoke collection chamber. In addition, the reinforcing members, the back plate, the side plates, and the air guide plates form a sealed space for installing functional modules and / or drive mechanisms. The addition of components to enclose the sealed space increases its volume, allowing it to accommodate more functional modules. This not only facilitates the expansion of the range hood's functions but also prevents the functional modules and drive mechanisms from being corroded by oil fumes, thus extending their service life.
[0007] Furthermore, the reinforcing member includes a plate body and a first connecting edge, a second connecting edge, and a third connecting edge disposed on the edge of the plate body. The first connecting edge is connected to the top surface of the side plate, the second connecting edge is connected to the bottom surface of the back plate, and the third connecting edge is connected to the air guide plate. The air guide plate is also connected to the top surfaces of the back plate and the side plate, respectively.
[0008] Furthermore, a reinforcing rib is provided between the first connecting edge and the plate body.
[0009] Furthermore, the reinforcing member is provided with a first side plate fixing hole and a second side plate fixing hole. The first side plate fixing hole and the second side plate fixing hole are not on the same plane. The reinforcing member is connected to the side plate through the first side plate fixing hole and the second side plate fixing hole.
[0010] Furthermore, a side plate hook is provided on the side of the reinforcing member, and a hook hole is provided on the corresponding side plate, into which the side plate hook is inserted.
[0011] Furthermore, the range hood also includes a motor bracket, which is connected to the top surface of the back plate, the side plate, and the reinforcing member.
[0012] Furthermore, the motor bracket is provided with a first connecting hole and a second connecting hole, which are not on the same plane. The motor bracket is connected to the reinforcing member through the first connecting hole and the second connecting hole.
[0013] Furthermore, the reinforcing member includes a plate, the plate having a height difference H with the sidewall plane of the side plate, so that the plate does not protrude from the sidewall plane of the side plate; the height difference H ≥ 2.5 mm.
[0014] Furthermore, multiple positioning plates are spaced apart on the wall of the LED lamp mounting hole. When the LED lamp module is installed in the LED lamp mounting hole, the positioning member on the side wall of the LED lamp module is inserted between two adjacent positioning plates.
[0015] Furthermore, the thickness of the reinforcing member is greater than the thickness of the side plate, back plate, and air guide plate. Attached Figure Description

[0023] To facilitate understanding of this utility model, a more comprehensive description will be given below with reference to the accompanying drawings.
[0024] It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to and integrated with the other component, or there may be an intervening component present. The terms "mounted," "one end," "the other end," and similar expressions used in this document are for illustrative purposes only.
[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.
[0026] This utility model specifically provides an embodiment of a range hood, see [link / reference]. Figure 1-7 The system includes a smoke collection chamber assembly, which comprises a back plate 1 and side plates 2 respectively connected to both sides of the back plate 1. The two side plates 2 are detachably connected to the back plate 1 by fasteners. A connecting plate 3 is also provided between the two side plates 2, and the two side plates 2 are connected as one unit through the connecting plate 3. The two side plates 2, the back plate 1, the air guide plate, and the connecting plate 3 together form the cavity of the smoke collection chamber. The smoke collection chamber assembly also includes at least one reinforcing member 4, which is connected to the back plate 1, the corresponding side plate 2, and the corresponding air guide plate 5. The reinforcing member 4, the back plate 1, the side plates 2, and the air guide plate 5 form a sealed space for installing functional modules and / or drive mechanisms. LED light mounting holes 6 and / or drive mechanism clearance holes 7 are provided on the reinforcing member 4. There can be one or two reinforcing members 4. In this embodiment, two reinforcing members 4 are used. Each reinforcing member 4 is connected to the corresponding side of the back plate 1, the corresponding side plate 2, and the corresponding air guide plate 5, which can form a stronger connection relationship and at the same time, can also form It can be divided into two sealed spaces to expand more functional modules; a functional module or a drive mechanism can be installed separately in the same sealed space, or both can be installed at the same time, depending on the needs; the reinforcing member 4 can be provided with both LED light mounting holes 6 and drive mechanism clearance holes 7, or only LED light mounting holes 6 can be provided. Only when a drive mechanism is installed in the sealed space is it necessary to provide the corresponding drive mechanism clearance hole 7 on the corresponding reinforcing member 4. Usually, the drive mechanism is used to make the flip cover of the range hood swing, so the swing arm of the drive mechanism needs to pass through the drive mechanism clearance hole 7 to connect with the flip cover.
[0027] In this embodiment, the range hood incorporates a reinforcing member 4, which connects to the back panel 1, the corresponding side panel 2, and the corresponding air guide plate 5. The reinforcing member 4 securely connects the back panel 1, side panel 2, and air guide plate 5, enhancing their strength. The cooperation between the fasteners and the reinforcing member 4 improves the overall structural strength of the smoke collection chamber. Since welding and grinding are unnecessary, the processing difficulty of the smoke collection chamber is reduced, improving the production efficiency of the range hood and lowering production costs. Simultaneously, the reinforcing member 4 is equipped with LED light mounting holes 6 and / or drivers. The mechanism avoidance hole 7 reduces the number of through holes to be opened on the side plate 2, air guide plate 5, or back plate 1, further improving the overall structural strength of the smoke collection chamber. In addition, the sealing space for installing functional modules and / or drive mechanisms is formed by the reinforcing member 4, the back plate 1, the side plate 2, and the air guide plate 5. Because of the addition of components for enclosing the sealing space, the volume of the sealing space can be increased, thereby accommodating more functional modules. This not only facilitates the expansion of the range hood's functions but also prevents the functional modules and drive mechanisms from being corroded by oil fumes, thus extending their service life.
[0028] In the preferred embodiment, see Figure 1-7 The reinforcing member 4 includes a plate 41 and a first connecting edge 42, a second connecting edge 43 and a third connecting edge 44 disposed on the edge of the plate 41. The first connecting edge 42 is connected to the top surface of the side plate 2, the second connecting edge 43 is connected to the bottom surface of the back plate 1, and the third connecting edge 44 is connected to the air guide plate 5. The air guide plate 5 is also connected to the top surfaces of the back plate 1 and the side plate 2 respectively. Specifically, a first side plate fixing hole 421 is provided on the first connecting edge 42. The reinforcing member 4 passes through the first side plate fixing hole 421 with a fastener and is fixedly connected to the top surface of the corresponding side plate 2. Two back plate fixing holes 431 are provided on the second connecting edge 43. The reinforcing member 4 passes through the back plate fixing hole 431 with a fastener and is fixedly connected to the bottom surface of the back plate 1. Two air guide plate fixing holes 441 are provided on the third connecting edge 44. The reinforcing member 4 passes through the air guide plate fixing hole 441 with a fastener and is fixedly connected to the corresponding air guide plate 5. In addition, a second side plate fixing hole 422 is also provided on the plate body 41 of the back plate 1. The reinforcing member 4 passes through the second side plate fixing hole 422 with a fastener and is fixedly connected to the side of the corresponding side plate 2. By fixing the reinforcing member 4 to the side, top, and bottom surfaces of the side plate 2 and the back plate 1, a triangular fixing point is formed, which can further effectively improve the overall structural strength of the smoke collection chamber.
[0029] In the preferred embodiment, see Figure 2 A reinforcing rib 8 is provided between the first connecting edge 42 and the plate 41. This increases the rigidity and strength of the first connecting edge 42 after bending, ensuring the stability of the connection between the first connecting edge 42 and the side plate 2.
[0030] In the preferred embodiment, see Figure 2 The reinforcing member 4 is provided with a first side plate fixing hole 421 and a second side plate fixing hole 422. Specifically, the first side plate fixing hole 421 is located on the first connecting edge 42 of the reinforcing member 4, while the second side plate fixing hole 422 is located on the plate body 41 of the reinforcing member 4. The first side plate fixing hole 421 and the second side plate fixing hole 422 are not on the same plane. The reinforcing member 4 is connected to the side plate through the first side plate fixing hole 421 and the second side plate fixing hole 422. By fixing the reinforcing member 4 to different surfaces of the side plate, the stability of the installation can be improved.
[0031] In the preferred embodiment, see Figure 2 and 3 A side plate hook 9 is provided on the side of the reinforcing member 4, and a hook hole 10 is provided on the corresponding side plate 2. The side plate hook 9 is inserted into the hook hole 10. When installing the reinforcing member 4, the side plate hook 9 can be pre-positioned by cooperating with the hook hole 10, which facilitates the rapid installation of the reinforcing member 4, improves production efficiency, and at the same time, it also plays a limiting role to prevent the reinforcing member 4 from having a large gap separating from the side plate 2 during later transportation.
[0032] In the preferred embodiment, see Figure 6 The range hood also includes a motor bracket 11, which is connected to the back plate 1, the top surface of the side plate, and the reinforcing member 4. The connection between the motor bracket 11 and the back plate 1, the top surface of the side plate, and the reinforcing member 4 provides three fixed positions for the motor bracket 11, ensuring the stability of the drive mechanism's movement.
[0033] In the preferred embodiment, see Figure 6 and 7 The motor bracket 11 is provided with a first connecting hole 111 and a second connecting hole 112. The first connecting hole 111 and the second connecting hole 112 are not on the same plane. The motor bracket 11 is connected to the reinforcing member 4 through the first connecting hole 111 and the second connecting hole 112. The motor bracket 11 is fixedly connected to different surfaces of the third connecting edge 44 of the reinforcing member 4 through the first connecting hole 111 and the second connecting hole 112, respectively. Specifically, it is connected to the motor bracket connecting hole 442 on the third connecting edge 44, which can further improve the installation stability of the motor bracket 11 and ensure the stability of the drive mechanism movement.
[0034] In the preferred embodiment, see Figure 1The enlarged view shows that the reinforcing member 4 includes a plate 41. The plate 41 has a height difference H with the side wall plane of the side plate 2, ensuring that the plate 41 does not protrude from the side wall plane of the side plate 2; the height difference H ≥ 2.5 mm. This effectively prevents the reinforcing member 4 from contacting the inner surface of the flip cover after it is closed, preventing oil stains from adhering to the flip cover and causing it to be unable to open smoothly. At the same time, it also prevents scratches on the coating on the reinforcing member 4.
[0035] In the preferred embodiment, see Figure 1 and 2 Multiple positioning plates 12 are spaced apart on the wall of the LED lamp mounting hole 6. When the LED lamp module 13 is installed in the LED lamp mounting hole 6, the positioning element 131 on the side wall of the LED lamp module 13 is inserted between two adjacent positioning plates 12. By inserting the positioning element 131 on the LED lamp module 13 between two adjacent positioning plates 12, the LED module can be quickly positioned, facilitating subsequent operations and improving installation efficiency.
[0036] In a preferred embodiment, the thickness of the reinforcing member 4 is greater than the thickness of the side plate, the back plate 1, and the air guide plate 5. By increasing the thickness of the reinforcing member 4, the overall strength of the smoke collection chamber can be further increased without increasing the thickness of sheet metal components such as the side plate and the back plate 1, thereby saving materials and reducing costs.
