[0004] To achieve the above objectives, this application discloses a range hood, which includes a smoke collection module, the smoke collection module comprising:

[0005] Side panels;

[0007] An oil baffle is disposed in front of the rear plate and between the side plates on opposite sides, the oil baffle being connected to the side plates and the rear plate; and

[0008] The sealing layer is formed by melting and molding a deformable porous material, which is suitable for pressing between the oil baffle and the side plate and between the oil baffle and the rear plate.

[0011] In some embodiments of this application, the smoke-collecting module further includes a covering layer that covers the joint between the oil baffle and the side plate, and also covers the joint between the oil baffle and the rear plate.

[0012] In some embodiments of this application, the covering layer also covers areas other than the seam.

[0013] In some embodiments of this application, the coating layer is formed by spraying raw materials.

[0014] In some embodiments of this application, the oil baffle has a corner, a first joint seam is formed between one side of the corner and the side plate, and a second joint seam is formed between the other side of the corner and the rear plate;

[0015] The smoke collection module also includes a sealing layer that covers the first joint and the second joint to seal them.

[0016] In some embodiments of this application, the sealing layer also covers the periphery of the first joint and the periphery of the second joint.

[0017] In some embodiments of this application, the sealing layer is formed by applying a sealant.

[0018] In some embodiments of this application, the oil baffle has a first flange and a second flange, and the deformable porous structural material is adapted to be pressed between the first flange and the side plate and between the second flange and the rear plate.

[0047] This application proposes a range hood, combining... Figure 1 , Figure 5 , Figure 8 , Figure 9 and Figure 11 As shown, the range hood includes a smoke collection module 200, which includes a side panel 1300, a rear panel 1200, an oil baffle 3000, and a sealing layer 4000. The rear panel 1200 has side panels 1300 on both sides. The oil baffle 3000 is located in front of the rear panel 1200 and between the two side panels 1300. The rear panel 1200 and the side panels 1300 need to be connected and fixed to the oil baffle 3000 respectively. The sealing layer 4000 is formed by melting and molding a deformable porous material. The deformable porous material needs to be pressed between the rear panel 1200 and the oil baffle 3000 and between the side panel 1300 and the oil baffle 3000, and then formed by melting and molding to form the sealing layer 4000.

[0048] By providing a deformable porous structural material between the rear plate 1200 and the oil baffle 3000, and between the side plate 1300 and the oil baffle 3000, the deformable porous structural material has a large compression capacity due to its porous structure and deformability, which facilitates the assembly of the rear plate 1200, the side plate 1300 and the oil baffle 3000. This allows the joints (4100 / 4200) between the rear plate 1200 and the oil baffle 3000, and between the side plate 1300 and the oil baffle 3000 to be as small as possible. After the deformable porous structural material is melted and formed, a sealing layer 4000 can be formed between the rear plate 1200 and the oil baffle 3000, and between the side plate 1300 and the oil baffle 3000, to prevent leakage.

[0049] Combination Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the range hood includes a smoke collection module 200 and an exhaust module 100. The exhaust module 100 is installed above the smoke collection module 200. The smoke collection module 200 is used to collect the fumes, and the exhaust module 100 is used to provide the power for exhaust. Generally, the exhaust module 100 has a fan. When the fan is working, the fumes first enter the smoke collection module 200 and then are transferred to the exhaust module 100, and finally discharged to the outside by the fan.

[0050] The smoke collection module 200 includes a top plate 1100, a rear plate 1200, side plates 1300, and a bottom plate 1400. The terms "front," "back," "left," and "right" are used with the range hood installed in the kitchen as a reference: the side facing the user is "front," the side away from the user is "rear," the left side corresponds to the user's left hand, and the right side corresponds to the user's right hand. The top plate 1100 has an opening (not shown in the figure), and the exhaust module 100 is installed at the opening in the top plate 1100. In a roughly horizontal direction, the top plate 1100 is larger than the exhaust module 100 to increase the smoke collection range of the smoke collection module 200. Side plates 1300 are provided on both the left and right sides of the top plate 1100, and the rear plate 1200 is located behind the top plate 1100 and the side plates 1300. The top plate 1100 and the rear plate 1200 can be formed by bending the same piece of plate and then connecting the side plates 1300 to it; alternatively, the top plate 1100 and the side plates 1300 can be formed by bending the same piece of plate and then connecting the rear plate 1200 to it; or the rear plate 1200 and the side plates 1300 can be formed by bending the same piece of plate and then connecting the top plate 1100 to it. The bottom plate 1400 is connected to the bottom of the rear plate 1200 and the side plates 1300. Through the cooperation of the top plate 1100, the rear plate 1200, the side plates 1300 and the bottom plate 1400, the smoke collection module 200 is roughly triangular when viewed from the left or right side.

[0051] The smoke collection module 200 also includes a baffle plate 1500, which is located in front of the rear plate 1200 and between the side plates 1300 on the left and right sides. The baffle plate 1500 has an air inlet 1510. The top plate 1100, side plates 1300, rear plate 1200 and baffle plate 1500 enclose a large internal space. When the exhaust module 100 is working, the fumes enter the internal space from the air inlet 1510 and then enter the exhaust module 100, where they are discharged to the outside.

[0052] Generally, the smoke collection module 200 also includes a control panel 2100, an upper panel 2200, an opening / closing panel 2300, and a lower panel 2400. The control panel 2100, upper panel 2200, opening / closing panel 2300, and lower panel 2400 are arranged from top to bottom and positioned at the front end of the smoke collection module 200, collectively forming a shield against the baffle plate 1500. The control panel 2100 controls the range hood, allowing for on / off operation, function selection, and display of operating parameters. The upper panel 2200 is positioned between the control panel 2100 and the opening / closing panel 2300, complementing the overall design of the smoke collection module 200. The opening / closing panel 2300 is configured to be movable, allowing the air inlet 1510 to be opened and closed. When the range hood is needed, the opening / closing panel 2300 moves to open the air inlet 1510, thereby achieving the extraction of cooking fumes. When the range hood is not needed, the opening / closing panel 2300 moves to close the air inlet 1510. Generally, the opening / closing panel 2300 can be opened and closed by rotating the air inlet 1510. Of course, the opening / closing panel 2300 can also be opened and closed by other methods. The bottom plate 2400 is located below the opening / closing panel 2300, and its design complements the smoke collection module 200.

[0053] When the range hood is working, the fumes enter the hood and flow from bottom to top. The oil mist particles in the fumes adhere to the corresponding parts along their path, forming grease. The grease flows downward under the influence of gravity. In addition, when the range hood is steam cleaned, the condensate formed also flows downward. In order to facilitate the collection of grease and condensate (hereinafter referred to as liquid dirt), an oil collection box 2500 needs to be installed at the lower position of the smoke collection module 200. The oil collection box 2500 is a component used to collect liquid dirt. The oil collection box 2500 is located inside the bottom panel 2400. When the liquid dirt collected by the oil collection box 2500 reaches a certain level, the bottom panel 2400 can be opened to expose the oil collection box 2500. The user can disassemble and clean the oil collection box 2500.

[0054] To facilitate the collection of liquid contaminants by the oil collection box 2500, an oil baffle 3000 is provided in this embodiment, combined with... Figure 4 and Figure 5As shown, the oil baffle 3000 is positioned lower on the smoke collection module 200 and above the oil collection box 2500. Specifically, the oil baffle 3000 is located in front of the rear plate 1200 and below the guide plate 1500, between the left and right side plates 1300. The oil baffle 3000 needs to be connected and fixed to the rear plate 1200, the side plate 1300, and the guide plate 1500 respectively. The oil baffle 3000 has an oil leakage hole 3600, which extends from top to bottom. The flowing liquid waste reaches the oil baffle 3000 and is blocked and guided by it. The liquid waste flows out from the oil drain hole 3600. The oil collection box 2500 is open to the top, and the liquid flowing out from the oil drain hole 3600 can directly enter the oil collection box 2500 under the action of gravity. The oil baffle 3000 makes it easier to guide the liquid waste to the oil collection box 2500, preventing the installation environment of the oil collection box 2500 from being contaminated.

[0055] When liquid contaminants flow downwards under the influence of gravity, they will move downwards along the rear plate 1200 and side plate 1300 (which form the inner wall). To prevent liquid contaminants from leaking between the rear plate 1200 and the oil baffle 3000, and between the side plate 1300 and the oil baffle 3000, and entering the environment of the oil collection box 2500, it is necessary to perform sealing treatment. This is because the areas between the rear plate 1200 and the oil baffle 3000, and between the side plate 1300 and the oil baffle 3000... The rear plate 1200 and the oil baffle 3000 are connected together, so inevitably there is a joint seam 4200 between the rear plate 1200 and the oil baffle 3000, and a joint seam 4100 between the side plate 1300 and the oil baffle 3000. The so-called joint seam (4100 / 4200) is the position where the two components meet. Liquid dirt can easily leak along the joint seam (4100 / 4200). Therefore, in this embodiment, a sealing layer 4000 is used for sealing. It can be understood that since the guide plate 1500 is located above the oil baffle 3000, liquid dirt flowing along the guide plate 1500 can fall directly into the oil baffle 3000.

[0056] The sealing layer 4000 is formed by melting and molding a deformable porous material. That is, when the oil baffle 3000 is assembled to the rear plate 1200 and the side plate 1300, the deformable porous material needs to be placed between the rear plate 1200 and the oil baffle 3000 and between the side plate 1300 and the oil baffle 3000. The so-called deformable porous material is a soft, deformable material with a porous structure. Understandably, when the oil baffle 3000 is installed on the rear plate 1200 and the side plate 1300, the oil baffle 3000 needs to fit tightly with the rear plate 1200 and the side plate 1300 to make the joint seam 4200 between the rear plate 1200 and the oil baffle 3000 and the joint seam 4100 between the side plate 1300 and the oil baffle 3000 as small as possible, so that the liquid dirt flowing along the rear plate 1200 and the side plate 1300 can flow into the oil baffle 3000 under the action of gravity.

[0057] Therefore, in this embodiment, a deformable porous material is provided between the rear plate 1200 and the oil baffle 3000, and between the side plate 1300 and the oil baffle 3000. After the oil baffle 3000 is connected in place, a fastening force will be generated between the rear plate 1200 and the oil baffle 3000, and between the side plate 1300 and the oil baffle 3000. The fastening force causes the deformable porous material to deform. It is precisely because of the porous and deformable characteristics of the deformable porous material that the deformable porous material has a large amount of compression, so that the deformable porous material is flattened as much as possible, thereby making the joint (4100 / 4200) as small as possible, and the rear plate 1200 and the oil baffle 3000, as well as the side plate 1300 and the oil baffle 3000, are in a mutually fitted state.

[0058] Furthermore, the fit between the rear plate 1200 and the side plate 1300 and the oil baffle 3000 needs to be designed to fit tightly together during the design phase, minimizing the amount of movement between the oil baffle 3000 and the rear plate 1200 and the side plate 1300. It is precisely because of the deformable and porous characteristics of the deformable porous material that the deformable porous material is less likely to interfere with the oil baffle 3000 during installation, making the installation of the oil baffle 3000 easier.

[0059] After the assembly of the rear plate 1200, side plate 1300, deformable porous material, and oil baffle 3000 is completed, the deformable porous material needs to melt at a certain temperature. The so-called certain temperature is sufficient to melt the deformable porous material. When the deformable porous material melts, the porous structure disappears. After cooling, a dense sealing layer 4000 is formed to achieve sealing. The sealing layer 4000 is formed between the rear plate 1200 and the oil baffle 3000 and between the side plate 1300 and the oil baffle 3000, which can prevent exposure and improve aesthetics.

[0060] In some embodiments of this application, the deformable porous material is a sponge. A sponge is a soft, porous material that is easily deformed and has a large compressibility, which is beneficial for the assembly of the oil baffle 3000. Sponges can be produced through foaming, and the manufacturing process is relatively mature; see related technologies for details. There are various materials used for sponges. For example, sponges are mainly prepared from chemically cross-linked polyethylene foam, ethylene-vinyl acetate copolymer, EPDM rubber, polyurethane, and / or polyethylene, and the choice can be made according to the actual situation. Chemically cross-linked polyethylene foam (XPE) is made by continuously foaming low-density polyethylene resin with a cross-linking agent and a foaming agent at high temperature. It has high tensile strength and finer pores. Ethylene-vinyl acetate copolymer (EVA) is produced by copolymerizing ethylene and vinyl acetate, and has good softness, sufficient elasticity, and certain corrosion resistance. Ethylene-propylene diene monomer (EPDM) rubber is a copolymer of ethylene, propylene, and a small amount of non-conjugated diene. It is a type of ethylene-propylene rubber and has excellent heat resistance, weather resistance, and aging resistance. Polyurethane (PU), also known as polyurethane, has good stability, chemical resistance, resilience, and mechanical properties. Polyethylene (PE) is a thermoplastic resin obtained by polymerizing ethylene, and its chemical properties are relatively stable.

[0061] Combination Figure 8 and Figure 12 As shown, in some embodiments of this application, the smoke collection module 200 further includes a covering layer 5000, which covers the joint 4200 between the rear plate 1200 and the oil baffle 3000, and covers the joint 4100 between the side plate 1300 and the oil baffle 3000. The covering layer 5000 provides double protection.

[0062] Range hoods are typically installed above the cooktop. During cooking, the generated fumes have a certain temperature, and the flowing fumes transfer this temperature to the sealing layer 4000. Furthermore, the sealing layer 4000 operates in a harsh environment, containing grease, condensation, and other liquid contaminants, and is also subject to airflow. To protect the sealing layer 4000 and prevent premature aging, this embodiment employs a covering layer 5000. The covering layer 5000 covers the joint 4200 between the rear panel 1200 and the oil baffle 3000, and also covers the joint 4100 between the side panel 1300 and the oil baffle 3000. In other words, the covering layer 5000 covers the sealing layer 4000, thus providing a degree of protection and preventing premature aging, ensuring a proper seal.

[0063] Since the sealing layer 4000 is formed by melting and molding a deformable porous material, irregular flow may occur when the deformable porous material is melted and molded. This results in irregular U-shaped openings 4300 or uneven openings 4300 between the edges of the rear plate 1200 and the oil baffle 3000, and between the edges of the side plate 1300 and the oil baffle 3000. The openings 4300 are prone to accumulating liquid dirt, which will adversely affect the sealing performance of the sealing layer 4000. However, by setting the covering layer 5000, the covering layer 5000 can fill the openings 4300, thereby avoiding the accumulation of liquid dirt and making it easier for liquid dirt to flow from the rear plate 1200 and the side plate 1300 to the oil baffle 3000.

[0064] Understandably, the cover layer 5000 provides protection for the sealing layer 4000. Therefore, the cover layer 5000 offers better protection than the sealing layer 4000, necessitating the selection of appropriate materials to form the cover layer 5000. For instance, if the materials of the cover layer 5000 and the sealing layer 4000 are different, the sealing layer 4000 will prioritize sealing performance, while the cover layer 5000 will prioritize protective performance.

[0065] Furthermore, continue to combine Figure 8 and Figure 12 As shown, in some embodiments of this application, the cover layer 5000 also covers the areas other than the joint (4100 / 4200). This enhances the bonding strength of the cover layer 5000, prevents it from loosening, and provides protection for other areas. If only the joint (4100 / 4200) is covered, the cover layer 5000 would be difficult to install due to its small size and would be prone to peeling. Therefore, in this embodiment, the cover layer 5000 also covers the areas other than the joint (4100 / 4200), making it easier to process, enhancing the bonding strength, and providing protection for areas other than the joint (4100 / 4200).

[0066] There are multiple ways to process the cover layer 5000. For example, the cover layer 5000 is formed by spraying raw materials. When spraying the raw materials, the raw materials can cover the sprayed area as much as possible, thereby forming a protective cover. The operation is convenient. That is, after the deformable porous structure material and the oil baffle 3000 are assembled to the rear plate 1200 and the side plate 1300, and the deformable porous structure material is melted and formed into a sealing layer 4000, the internal structure of the smoke collection module 200 is then sprayed with raw materials. The sprayed area can form an effective protective cover, and it is not easy to leave dead corners.

[0067] For example, the raw material can be pure polyester powder coating. Pure polyester powder coating is a coating used to coat the surface of the object to be protected. It is made of hydroxyl polyester resin, curing agent, pigment, filler and additives. When applied to the surface of the workpiece, it can form a protective coating, decoration or special properties (marking, insulation, wear resistance, etc.). It can be understood that pure polyester powder coating needs to be melted at high temperature after spraying to form a 5000-degree coating.

[0068] Combination Figure 5 , Figure 6 , Figure 7 , Figure 9 , Figure 10 and Figure 11 As shown, in some embodiments of this application, the oil baffle 3000 includes a corner portion 3500, a first joint seam 4110 is formed between the side plate 1300 and one side of the corner portion 3500, and a second joint seam 4210 is formed between the rear plate 1200 and the other side of the corner portion 3500. The smoke collection module 200 also includes a sealing layer 6000, which covers the second joint seam 4210 and the first joint seam 4110 and achieves a seal between the second joint seam 4210 and the first joint seam 4110.

[0069] The first joint 4110 is a part of the joint 4100 formed between the side plate 1300 and the oil baffle 3000, and the second joint 4210 is a part of the joint 4200 formed between the rear plate 1200 and the oil baffle 3000. The so-called corner 3500 refers to the part where the rear and left sides of the oil baffle 3000 intersect, and the part where the rear and right sides of the oil baffle 3000 intersect. Taking the left corner 3500 as an example, the corner 3500 of the oil baffle 3000 forms a significant turn from the rear to the left. A deformable porous material is disposed between the corner 3500 and the rear plate 1200 and side plate 1300, requiring it to fit together with the corner 3500, rear plate 1200, and side plate 1300 of the oil baffle 3000. This fit is difficult, and the deformable porous material is prone to poor crimping, leading to a lack of sealing when melted and molded into the sealing layer 4000. Therefore, in this embodiment, a sealing layer 6000 is provided to enhance the seal. That is, firstly, the deformable porous structural material is assembled between the oil baffle 3000 and the rear plate 1200 and the side plate 1300. Then, the deformable porous structural material is melted and formed into a sealing layer 4000. Next, a covering layer 5000 is set, which covers the joint 4200 between the rear plate 1200 and the oil baffle 3000 and the joint 4100 between the side plate 1300 and the oil baffle 3000. Finally, a sealing layer 6000 is set, which covers the second joint 4210 and the first joint 4110.

[0070] Understandably, the so-called sealing layer 6000 is made of a material that can perform a sealing function, thereby forming a seal. For example, the sealing layer 6000 is formed by applying a sealant. The sealant is a sealing material with a certain degree of adhesion, used to fill gaps and perform a sealing function. The type of sealant can be selected according to the actual situation, effectively improving the sealing performance between the corner 3500 of the oil baffle 3000 and the side plate 1300 and the rear plate 1200.

[0071] Combination Figure 8 , Figure 12 , Figure 13 and Figure 14 As shown, in some embodiments of this application, the oil baffle 3000 has flanges, which include a first flange 3100 and a second flange 3200. The first flange 3100 is disposed on the left and right sides of the oil baffle 3000, while the second flange 3200 is disposed on the rear side of the oil baffle 3000. During assembly, the deformable porous material needs to be pressed between the side plate 1300 and the first flange 3100, and also needs to be pressed between the rear plate 1200 and the second flange 3200.

[0072] Understandably, since the oil baffle 3000 needs to cooperate with the rear plate 1200 and the side plate 1300 to achieve compression bonding of the deformable porous material, this embodiment increases the contact area with the deformable porous material by setting the first flange 3100 and the second flange 3200. When the deformable porous material is melted and formed into the sealing layer 4000, the sealing area is increased, effectively improving the sealing effect. Furthermore, it is precisely by setting the first flange 3100 and the second flange 3200, which respectively cooperate with the side plate 1300 and the rear plate 1200, that the support area is large, making the oil baffle 3000 more stable during installation and effectively achieving compression bonding of the deformable porous material.

[0073] Combination Figure 14 and Figure 15 As shown, in some embodiments of this application, in order to further facilitate the installation of the oil baffle 3000 onto the rear and side plates 1300, the oil baffle 3000 also has a locking protrusion 3400. The second flange 3200 is provided with the locking protrusion 3400, and the rear plate 1200 is provided with an insertion hole 1210. When installing the oil baffle 3000, the locking protrusion 3400 is inserted into the insertion hole 1210, thus forming the initial positioning of the oil baffle 3000, and then further tightening the oil baffle 3000.

[0074] For example, both the first flange 3100 and the second flange 3200 are bent downwards, and the latching protrusion 3400 extends downwards accordingly. The insertion hole 1210 is formed by punching a portion of the rear plate 1200, with the insertion hole 1210 opening upwards. The latching protrusion 3400 is inserted into the insertion hole 1210 from top to bottom, thus forming the initial installation and positioning of the oil baffle 3000. The setting of the insertion hole 1210 also provides support for the oil baffle 3000. Since the first flange 3100 and the second flange 3200 are bent downwards, the corresponding insertion hole 1210 is set below the joint (4100 / 4200), thus preventing liquid dirt from entering the insertion hole 1210 and leaking when flowing from top to bottom.

[0075] Continue to combine Figure 14 and Figure 15 As shown, in some embodiments of this application, the first flange 3100 and the second flange 3200 are further fastened to the side plate 1300 and the rear plate 1200 through the following scheme: the first flange 3100 and the second flange 3200 are provided with a first fastening hole 3300, while the side plate 1300 and the rear plate 1200 are provided with a second fastening hole 1220. A screw is used to pass through the first fastening hole 3300 and the second fastening hole 1220 to achieve a fastening connection, which is convenient and quick. It is understood that when using screw connection, the screw needs to pass through the deformable porous structural material; of course, a riveting connection can also be used for fastening.
