Description

Technical Field

[0001] This invention belongs to the field of kitchen appliance technology, specifically relating to a range hood. Background Technology

[0002] The cooking process in traditional Chinese cuisine includes frying, stir-frying, deep-frying, and roasting, which generates a lot of oil fumes. These fumes not only seriously pollute the kitchen environment, but also pose a significant health risk to kitchen workers who are exposed to them for extended periods, potentially leading to cancer. Therefore, range hoods are widely used in kitchens.

[0003] Currently, range hoods on the market come in various forms, but they generally include a smoke collection hood and a main housing installed on top of the smoke collection hood, which is connected to the smoke collection hood. During installation, to ensure the airtightness between the main housing and the smoke collection hood, a large number of screws are often required for tightening, resulting in low installation efficiency and high labor intensity for workers, which seriously affects the production efficiency of range hoods.

[0004] Therefore, designing a range hood that can both ensure the sealing between the smoke collection hood and the main body and improve installation efficiency has become a technical problem that urgently needs to be solved by those skilled in the art.

[0005] In view of this, the present invention is proposed. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a range hood that adapts the shape of the interface at the bottom of the main body to the top of the smoke collection hood, and provides a rolled edge arranged circumferentially on the inner side of the interface, so that at least part of the bottom of the main body is inserted into the smoke collection hood from the interface at the top of the smoke collection hood and is locked in the rolled edge, thereby ensuring the sealing between the smoke collection hood and the main body. At the same time, it can improve the installation efficiency of the range hood and overcome the problems of low efficiency and high labor intensity when workers disassemble and assemble range hoods in the prior art.

[0007] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by the present invention is as follows:

[0008] A range hood includes a smoke collection hood and a main body. The top of the smoke collection hood is provided with an interface for connecting with the main body. The inner side of the interface is provided with a rolled edge arranged in a circumferential direction. The lower end of the main body extends into the interface at least partially and is engaged within the rolled edge.

[0009] In the above solution, the lower end of the main housing is at least partially inserted into the interface at the top of the smoke hood, and the main housing is limited by the rolled edge on the inside of the interface, which can not only ensure the sealing between the smoke hood and the main housing, but also improve the assembly efficiency between the two.

[0010] Furthermore, the rolled edge includes:

[0011] The first extension extends vertically downward from the interface;

[0012] The second extension bends upward from the inner side of the lower end of the first extension.

[0013] Furthermore, the second extension extends from bottom to top toward the side closer to the first extension, with the lower end of the main body sandwiched between the first and second extensions.

[0014] In the above scheme, the lower end of the main housing is inserted between the first extension and the second extension. The connection between the first extension and the second extension is arc-shaped, and the first extension and the second extension are elastically fitted together. The distance between the upper end of the second extension and the first extension is less than the wall thickness of the main housing, thereby clamping the lower end of the main housing between the first extension and the second extension, further improving the sealing between the smoke hood and the main housing, and at the same time, improving the installation strength between the two.

[0015] Furthermore, the rolled edge also includes a third extension extending upward from the upper end of the second extension, the third extension extending from bottom to top toward the side away from the first extension.

[0016] In the above scheme, by setting a third extension, the distance between the upper end of the third extension and the first extension is relatively large, so as to guide the main body and facilitate the insertion of the lower end of the main body between the second extension and the first extension, thereby further improving the installation efficiency.

[0017] Furthermore, it also includes:

[0018] The gripper is located on the inside of the interface;

[0019] The card slot is located on the main body and corresponds to the card claw.

[0020] The claw engages within the slot.

[0021] In the above scheme, the slot can be a groove set on the main body, and the groove is set one-to-one with the claw. When the lower end of the main body is inserted into the bottom of the rolled edge, the claw engages in the corresponding slot, and the lower end of the claw abuts against the lower end of the slot to limit the relative position between the main body and the smoke hood, thereby improving the installation strength between the main body and the smoke hood.

[0022] Furthermore, the gripper includes:

[0023] The connecting part has one end connected to the interface, and the other end extends from top to bottom towards the inside of the interface.

[0024] The connecting part extends vertically downward from the lower end of the connecting part;

[0025] The slot is a hollowed-out groove set on the main body.

[0026] In the above solution, the connecting part and the snap-fit ​​part are elastically fitted. By setting the connecting part to be inclined from top to bottom towards the inside of the interface, it can guide the main body, allowing the main body to be smoothly inserted into the interface at the top of the smoke hood.

[0027] Furthermore, the rolled edges are arranged in multiple spaced-apart configurations, and the multiple claws are respectively positioned at the gap between two adjacent rolled edges.

[0028] Furthermore, the smoke hood includes a smoke hood body and a baffle;

[0029] The smoke hood body includes two opposing side plates and a back plate connected to the rear end of the side plates. The upper ends of the two side plates are bent inward and extended respectively, and a notch is left between the upper ends of the two side plates.

[0030] The baffle includes a front sidewall disposed opposite to the back panel, and a left sidewall and a right sidewall extending from the left and right ends of the front sidewall toward the back panel, with the upper ends of the left sidewall and the right sidewall corresponding to the notch.

[0031] The upper end of the front side wall, the upper end of the back plate, and the upper end of the side plate of the baffle together constitute the interface.

[0032] In the above scheme, the left side plate, right side plate, and back plate together form a smoke collection hood. The upper ends of the left side plate and right side plate extend inward to form the top surface of the smoke collection hood. A baffle is set in the space enclosed by the left side plate, right side plate, and back plate, and together with the back plate, forms a smoke collection chamber with openings at both the upper and lower ends. The main body extends at least partially into the upper opening of the smoke collection chamber.

[0033] Furthermore, the rolled edge portion is connected to the smoke collection hood body and partially connected to the baffle;

[0034] The rolled edges at the left and right ends of the interface are connected to the side plates, the rolled edge at the rear end of the interface is connected to the back plate, and the rolled edge at the front end of the interface is connected to the baffle.

[0035] In the above solution, by setting part of the rolled edge on the smoke hood body and part of it on the baffle, the lower end of the main box can be respectively snapped onto the baffle and the smoke hood body, improving the assembly effect of the baffle. At the same time, it can reduce the load on the upper part of the baffle and make the smoke collection chamber more stable.

[0036] Furthermore, honeycomb holes are provided on the left and right walls of the baffle, and sound-absorbing cotton is installed at the honeycomb holes.

[0037] In the above solution, the sound-absorbing cotton is adhered to the honeycomb holes on the left and right side walls of the baffle. The contour edges of the left and right side walls are connected to the inner peripheral wall of the smoke collection hood, so that the left and right sides of the smoke collection chamber form relatively closed noise reduction cavities, which improves the noise reduction effect and also prevents the oil fume airflow from directly entering the noise reduction cavity.

[0038] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art:

[0039] 1. This invention adapts the shape of the interface between the lower end of the main housing and the top of the smoke hood, and sets a rolled edge arranged circumferentially on the inner side of the interface, so that at least part of the lower end of the main housing is inserted into the smoke hood from the interface at the top of the smoke hood and is locked in the rolled edge, thereby ensuring the sealing between the smoke hood and the main housing, and improving the installation efficiency of the range hood.

[0040] 2. By setting mutually cooperating claws and slots, the present invention further enhances the installation strength and sealing between the main body and the smoke collection hood, preventing the lower end of the main body from detaching from the clamping of the rolled edge.

[0041] 3. By setting honeycomb holes on the left and right sides of the smoke collection chamber and placing sound-absorbing cotton at the honeycomb holes, the present invention can reduce the operating noise generated by the fan rotation and improve the user experience.

[0061] Example 1

[0062] like Figures 1 to 11 As shown in the embodiment of the present invention, a range hood is introduced, including a smoke collection hood 100 and a main box 200 installed above the smoke collection hood 100. The main box 200 includes a main box body 201 and a decorative cover 202 sleeved on the outside of the main box body 201. The lower end of the main box body 201 is connected to the smoke collection hood 100.

[0063] In this embodiment, the smoke hood 100 includes a smoke hood body, which includes a back plate 103 and left and right side plates 102 disposed on the left and right sides of the back plate 103, respectively. The two side plates 102 are disposed opposite each other, and the upper ends of the side plates 102 are bent inward and extended. The rear ends of the two side plates 102 are respectively connected to the back plate 103. In this embodiment, the left and right side plates 102 and the back plate 103 are connected to each other by screws and / or rivets. A notch is left between the upper ends of the left and right sides, thus forming a smoke hood body with a notch at the top.

[0064] The smoke collection hood body is provided with a baffle 104. The baffle 104 and the back plate 103 surround to form a smoke collection chamber 101. The upper and lower ends of the smoke collection chamber 101 are respectively provided with openings. The upper opening corresponds to the notch and is used to connect with the main box 201. The lower opening is used to collect the oil fumes.

[0065] The baffle 104 includes a front sidewall opposite to the back plate 103, and a left sidewall and a right sidewall perpendicular to the back plate 103. The left sidewall and the right sidewall are inclined from bottom to top into the smoke collection chamber 101, so that the smoke collection chamber 101 forms a shape with a large opening at the bottom and a small opening at the top, which facilitates the collection of oil fumes flowing into it.

[0066] In this embodiment, by setting openings at the upper and lower ends of the smoke collection chamber 101, and by setting the left and right side walls of the smoke collection chamber 101 to move closer to each other from bottom to top, the diameter of the smoke collection chamber 101 gradually increases from top to bottom, thereby increasing the negative pressure zone and accelerating the air flow rate in the smoke collection chamber 101.

[0067] In this embodiment, the top of the smoke hood 100 is provided with an interface 105 for communication with the main housing 201. The lower end of the main housing 201 is adapted to the shape of the interface 105 on the top of the smoke hood 100, and the lower end of the main housing 201 is at least partially inserted into the interface 105 and communicates with the upper opening of the smoke collection chamber 101. A connecting structure is provided at the interface 105, and the main housing 201 and the smoke hood 100 are connected to each other through the connecting structure to complete the assembly.

[0068] like Figure 4 As shown, in this embodiment, the inner side of the interface 105 is provided with a rolled edge 300 arranged circumferentially along the interface 105. The rolled edge 300 is used to support the main box 201, and the lower end of the main box 201 is at least partially engaged in the rolled edge 300.

[0069] like Figure 9 and Figure 11 As shown, in this embodiment, the rolled edge 300 includes a first extension 301 extending vertically downward from the interface 105, and a second extension 302 extending upward from the inner side of the lower end of the first extension 301. The connection between the first extension 301 and the second extension 302 is arc-shaped, and the first extension 301 and the second extension 302 are elastically fitted together. The lower end of the main housing 201 is inserted between the first extension 301 and the second extension 302. The upper end of the second extension 302 extends from bottom to top towards the side close to the first extension 301. The distance between the upper end of the second extension 302 and the first extension 301 is less than the wall thickness of the main housing 201, thereby clamping the lower end of the main housing 201 between the first extension 301 and the second extension 302, further improving the sealing between the smoke hood 100 and the main housing 201, and at the same time, improving the installation strength between the two.

[0070] The rolled edge 300 also includes a third extension 303 extending upward from the upper end of the second extension 302. The third extension 303 extends upward from the bottom to the side away from the first extension 301. By providing the third extension 303, the distance between the upper end of the third extension 303 and the first extension 301 is made larger, so as to guide the main housing 201 and facilitate the insertion of the lower end of the main housing 201 between the second extension 302 and the first extension 301, thereby further improving the installation efficiency.

[0071] In this embodiment, the interface 105 at the top of the smoke hood 100 is formed by the left side of the upper end of the right side plate 102, the right side of the upper end of the left side plate 102, the back plate 103 between the two, and the upper end of the front side wall of the baffle 104. The upper end of the left side wall of the baffle 104 is connected to the lower right side of the upper end of the left side plate 102, and the upper end of the right side wall of the baffle 104 is connected to the lower left side of the upper end of the right side plate 102.

[0072] Preferably, in this embodiment, the rolled edges 300 are arranged at intervals and have the same or different lengths. The rolled edges 300 located on the left and right sides of the interface 105 are respectively connected to the left and right side plates 102, the rolled edges 300 located on the rear side of the interface 105 are connected to the back plate 103, and the rolled edges 300 located on the front side of the interface 105 and the upper ends of the claws 400 are connected to the front side wall of the baffle 104. The lower end of the main housing 201 is respectively engaged in the rolled edges 300 on the front, rear, left, and right sides, so that the main housing 201 is assembled. By setting some rolled edges 300 on the smoke hood body and some on the baffle 104, the lower end of the main housing 201 can be engaged in the baffle 104 and the smoke hood body respectively, improving the assembly effect of the baffle 104. At the same time, it can reduce the load on the upper end of the baffle 104 and make the smoke collection chamber 101 more stable.

[0073] Preferably, in this embodiment, the top of the left and right side walls of the baffle 104 are fitted over the outer sides of the rolled edges 300 on the left and right sides of the interface 105. The upper inner sides of the left and right side walls of the baffle 104 are provided with protruding ribs 1041. The protruding ribs 1041 extend along the width direction of the left and right side walls and are correspondingly provided below the rolled edges 300 to seal the gap between the rolled edges 300 and the baffle 104, preventing oil fumes from escaping from the gap between the rolled edges 300 and the baffle 104.

[0074] Preferably, in this embodiment, the smoke hood 100 and the main housing 201 are further provided with a cooperating claw 400 and a slot, the claw 400 being engaged in the slot to further fix the relative position of the main housing 201.

[0075] Specifically, the claw 400 is disposed inside the interface 105, including a connecting part 401 and a locking part 402. One end of the connecting part 401 is connected to the interface 105, and the other end extends obliquely downwards towards the inside of the interface 105. The locking part 402 is configured as a sheet extending vertically downwards from the lower end of the connecting part 401. In this embodiment, the connecting part 401 and the locking part 402 are elastically engaged. By configuring the connecting part 401 to be obliquely inclined downwards towards the inside of the interface 105, it can guide the main housing 201, allowing the main housing 201 to be smoothly inserted into the interface 105 at the top of the smoke hood 100.

[0076] The slot is provided on the main housing 201 and corresponds to the claw 400. The width of the slot is greater than or equal to the width of the locking part 402, and the length of the slot is greater than or equal to the length of the locking part 402, so that when the lower end of the main housing 201 abuts against the bottom of the rolled edge 300, the locking part 402 of the claw 400 can smoothly engage in the slot.

[0077] In this embodiment, the slot can be a groove provided on the main housing 201. The groove is provided in a one-to-one correspondence with the claw 400. When the lower end of the main housing 201 is inserted into the bottom of the rolled edge 300, the claw 400 is engaged in the corresponding slot. The lower end of the claw 400 abuts against the lower end of the slot to limit the relative position between the main housing 200 and the smoke hood 100, improve the installation strength between the main housing 201 and the smoke hood 100, and at the same time realize the rapid positioning and assembly between the main housing 201 and the smoke hood 100.

[0078] In this embodiment, the slot can also be set as a hollow slot. The locking part 402 of the claw 400 can be locked in the slot or locked on the inside of the slot to limit the main body 201 and prevent the main body 201 from detaching from the interface 105.

[0079] Preferably, in this embodiment, the plurality of claws 400 are respectively disposed at the gap between two adjacent rolled edges 300.

[0080] like Figures 1 to 6 As shown, in this embodiment, the front end of the side plate 102 is set as a sloping side that tilts backward from top to bottom, and is provided with a bent part 1021 that bends and extends inward. The left and right ends of the baffle 104 are respectively engaged between the bent part 1021 and the back plate 103, and are connected to the smoke hood body by screws and / or rivets, thereby ensuring the stability of the baffle 104 assembly.

[0081] In this embodiment, a base plate is provided below the smoke collection hood body. The left and right sides of the base plate are connected to the lower ends of the left and right side plates 102, respectively, and the rear side of the base plate is connected to the lower end of the back plate 103.

[0082] Preferably, in this embodiment, a reinforcing plate 107 is provided between the bent portion 1021 below the baffle 104 and the back plate 103. The upper end of the reinforcing plate 107 is adapted to the shape of the bottom of the baffle 104, and the lower end of the reinforcing plate 107 is adapted to the shape of the bottom plate. The upper and lower ends of the reinforcing plate 107 abut against the bottom of the baffle 104 and the bottom plate, respectively, thereby dividing the internal space of the enclosure into the flue cavity in the middle and the mounting cavities on both sides. At the same time, the setting of the reinforcing plate 107 can support the baffle 104 and further enhance the stability of the assembly of the baffle 104.

[0083] Preferably, in this embodiment, the back plate 103 is provided with a mounting groove 1031. The direction of the mounting groove 1031 is the same as that of the rear end of the reinforcing plate 107 and the rear end of the baffle 104. The rear ends of the reinforcing plate 107 and the baffle 104 are both installed in the mounting groove 1031. The rear ends of the reinforcing plate 107 and the baffle 104 are both provided with a folded edge 1043 that bends outward toward the outside of the flue cavity. The width of the folded edge 1043 is adapted to the width of the mounting groove 1031. The reinforcing plate 107 and the baffle 104 are installed on the back plate 103 through the folded edge 1043. The folded edge 1043 fits against the bottom of the mounting groove 1031 and is connected to the back plate 103 by rivets.

[0084] Preferably, in this embodiment, honeycomb holes 1042 are formed on the left and right sides of the baffle 104, and sound-absorbing cotton is provided at the honeycomb holes 1042. The contour edges of the left and right sides are connected to the inner peripheral wall of the smoke collection hood 100, so that the left and right sides of the smoke collection chamber 101 respectively form relatively closed noise reduction chambers, which improves the noise reduction effect and at the same time prevents the oil fume airflow from directly entering the noise reduction chamber. The sound-absorbing cotton is pasted at the honeycomb holes 1042 on the left and right sides of the baffle 104.

[0085] Example 2

[0086] like Figures 1 to 11 As shown in this embodiment, a reinforcing plate 107 is provided between the bent portion 1021 below the smoke collection chamber 101 and the back plate 103. The upper end of the reinforcing plate 107 is adapted to the shape of the bottom of the baffle 104, and the lower end of the reinforcing plate 107 is adapted to the shape of the bottom plate. The upper and lower ends of the reinforcing plate 107 abut against the bottom of the baffle 104 and the bottom plate, respectively, thereby dividing the internal space of the enclosure into an independent flue chamber and an installation chamber. At the same time, the reinforcing plate 107 can support the baffle 104 and further enhance the stability of the baffle 104 assembly.

[0087] Range hoods typically contain electronic components and mechanical movement mechanisms for on / off control. In this embodiment, all electronic components and mechanical movement mechanisms are installed within the mounting cavity, which is used for the circulation of cooking fumes. When the range hood is running, cooking fumes only flow through the flue cavity, with very little entering the mounting cavity. This reduces contamination of the components within the mounting cavity by cooking fumes, preventing short circuits or jamming due to grease buildup, and ensuring the normal operation of all components and the range hood itself.

[0088] In this embodiment, a smoke inlet chamber 106 is provided below the smoke collection chamber 101. The upper end of the smoke inlet chamber 106 is connected to the smoke collection chamber 101. An opening is provided at the front end of the smoke inlet chamber 106. The smoke inlet chamber 106 and the smoke collection chamber 101 together constitute the flue chamber.

[0089] In this embodiment, the back plate 103, the two reinforcing plates 107 and the bottom plate below the smoke collection chamber 101 together form a flue cavity, and a smoke guiding structure is provided at the front opening of the flue cavity.

[0090] like Figure 2 As shown, the smoke guiding structure includes a filter plate 1061 and a guide plate 1062. The filter plate 1061 extends downward from the upper end of the front opening of the smoke inlet chamber 106 and tilts backward from top to bottom. The guide plate 1062 extends downward from the lower end of the filter plate 1061 and tilts forward from top to bottom. Its lower end is sealed to the lower end of the front opening of the smoke inlet chamber 106. The filter plate 1061 is provided with an air inlet. By setting the smoke guiding structure, the guiding effect of the flowing fumes can be improved, the airflow at the air inlet can be prevented from becoming turbulent, and the smoke extraction effect of the range hood can be improved. The left and right ends of the filter plate 1061 and the guide plate 1062 respectively abut against the inner sides of the two reinforcing plates 107, which can ensure the suction at the air inlet and prevent the fumes from escaping from the left and right sides of the filter plate 1061 and the guide plate 1062.

[0091] Preferably, in this embodiment, to ensure installation strength, the upper end of the guide plate 1062 abuts against the back plate 103, and the lower end of the filter plate 1061 abuts against the upper end of the guide plate 1062, and is arranged perpendicular to the guide plate 1062. To ensure smoke extraction effect, the angle between the filter plate 1061 and the horizontal direction is set to be less than or equal to 45 degrees; the angle between the guide plate 1062 and the horizontal direction is set to be greater than or equal to 45 degrees and less than 90 degrees.

[0092] Preferably, in this embodiment, the air inlet is strip-shaped, and multiple strip-shaped air inlets are evenly arranged horizontally on the filter plate 1061, so that the filter plate 1061 forms a grid shape, which can not only ensure the air inlet area, but also increase the flow rate of oil fumes at a single air inlet and improve the smoke extraction effect.

[0093] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way.
