Abstract
Description
Technical Field
[0001] This utility model relates to the field of cooking equipment technology, and in particular to a range hood and integrated stove. Background Technology
[0002] An integrated cooktop is a kitchen appliance that integrates multiple functions into one unit, such as a combination of "fume hood + cooktop + storage", "fume hood + cooktop + disinfection", or "fume hood + cooktop + steaming / baking".
[0003] In related technologies, integrated cooktops include range hoods. The range hood housing has a smoke collection chamber and an air outlet communicating with the smoke collection chamber. The air outlet is connected to the aluminum foil duct using clamps, and silicone is applied between the air outlet and the aluminum foil duct.
[0004] However, the clamp may experience reduced sealing during the clamping process. Utility Model Content
[0005] This utility model provides a range hood and integrated stove to solve the problem of reduced sealing performance that occurs during the clamping process.
[0006] In a first aspect, this utility model embodiment provides a range hood, comprising:
[0007] The housing has a connected smoke collection chamber and an air outlet;
[0008] An elastic ring is fitted onto the outer peripheral wall of the air outlet.
[0009] An aluminum foil duct, wherein the aluminum foil duct is fitted onto the elastic ring;
[0010] Fasteners are fitted on the outside of the connection between the aluminum foil duct and the elastic ring, and clamp the aluminum foil duct.
[0011] In one possible implementation, the aluminum foil duct includes an aluminum foil tube and a gasket, the gasket being connected inside the aluminum foil tube and connected to the outer peripheral wall of the elastic ring.
[0012] With this design, the surface of the gasket is flatter than that of the aluminum foil tube, allowing the gasket to fit tightly against the elastic ring, increasing friction and improving the seal between the aluminum foil duct and the air outlet.
[0013] In one possible implementation, the gasket is a polyvinyl chloride gasket, and the elastic ring is a rubber component.
[0014] With this setup, since the static friction coefficient of the PVC gasket is greater than that of the aluminum part, the friction force can be increased through the contact between the gasket and the elastic ring, which can strengthen the fixation between the aluminum foil duct and the air outlet.
[0015] In one possible implementation, the inner circumference of the washer is greater than the outer circumference of the elastic ring.
[0016] With this configuration, the gasket can be easily placed on the outside of the elastic ring during the connection process between the aluminum foil duct and the elastic ring, which can improve the installation efficiency of the aluminum foil duct and the air outlet.
[0017] In one possible implementation, the size of the gasket is greater than or equal to the size of the elastic ring in the direction extending along the central axis of the air outlet.
[0018] With this configuration, the gasket of the aluminum foil duct can cover the elastic ring after they are attached, which can improve the sealing between the aluminum foil duct and the air outlet.
[0019] In one possible implementation, at least one limiting rib is provided on the outer peripheral wall of the air outlet, and the limiting rib is located on the side away from the smoke collection chamber at the connection between the elastic ring and the aluminum foil duct.
[0020] This design, with its limiting ribs, can block the elastic ring, preventing it from falling off the outer periphery of the air outlet onto the wall, and strengthening the fixation between the aluminum foil duct and the air outlet.
[0021] In one possible implementation, the elastic ring abuts against the limiting rib and the housing respectively on both sides in the direction of extension of the central axis of the air outlet.
[0022] With this configuration, the limiting ribs can limit the elastic ring in the direction of the extension of the central axis of the air outlet, so that the elastic ring remains stable on the outer peripheral wall of the air outlet, thereby enhancing the stability between the aluminum foil duct and the air outlet.
[0023] In one possible implementation, the inner circumference of the elastic ring is less than or equal to the outer circumference of the air outlet.
[0024] With this configuration, when the elastic ring is placed on the outer peripheral wall of the air outlet, the inner ring of the elastic ring can fit snugly against the outer peripheral wall of the air outlet, ensuring a stable connection between the elastic ring and the air outlet and strengthening the fixation between the aluminum foil duct and the air outlet.
[0025] In one possible implementation, the air outlet is an elliptical opening.
[0026] Secondly, this utility model embodiment provides an integrated stove, including the range hood described in the first aspect.
[0027] This utility model provides a range hood and integrated stove. By setting an elastic ring between the aluminum foil duct and the air outlet, the aluminum foil duct is supported by the elastic ring, which can reduce wrinkles at the connection between the aluminum foil duct and the elastic ring, and reduce bending of the aluminum foil duct during the clamping process of the fasteners. The elastic ring can disperse pressure during the clamping process of the aluminum foil duct, avoid local stress concentration in the aluminum foil duct, thereby reducing damage to the outer skin of the aluminum foil duct, reducing wear of the aluminum foil duct by the fasteners, and improving the sealing between the aluminum foil duct and the air outlet during the clamping process of the fasteners.

[0045] As described in the background section, integrated cooktops include a range hood. The range hood's housing has a smoke collection chamber and an air outlet communicating with the smoke collection chamber. The air outlet is connected to the aluminum foil duct using clamps, and silicone is applied between the air outlet and the aluminum foil duct. During the clamping process, a decrease in sealing performance can occur. The inventors discovered that this problem arises because, during clamping, the aluminum foil duct experiences increased wrinkles and localized stress concentration, leading to damage to the outer sheath of the aluminum foil duct and thus reducing the seal at the connection between the aluminum foil duct and the air outlet.
[0046] To address the aforementioned issues, the range hood and integrated cooktop provided in this embodiment of the invention utilize an elastic ring between the aluminum foil duct and the air outlet. The aluminum foil duct is supported by the elastic ring, reducing wrinkles at the connection point and minimizing bending during fastener clamping. The elastic ring also disperses pressure during clamping, preventing localized stress concentration and thus reducing damage to the outer sheath of the duct. Furthermore, it reduces wear on the duct from the fasteners and improves the seal between the aluminum foil duct and the air outlet during clamping.
[0047] The range hood and integrated stove provided in this utility model embodiment will be described in detail below with reference to specific embodiments.
[0048] This utility model provides a range hood for use in integrated cooktops.
[0049] See Figure 1 As shown, the range hood includes a housing 10 and an aluminum foil duct 30. The housing 10 has a smoke collection chamber and an air outlet 101, which are connected to each other. The air outlet 101 is connected to the aluminum foil duct 30.
[0050] In some examples, the first direction of the housing 10 can be the X-axis, the second direction can be the Y-axis, and the third direction can be the Z-axis, with the X, Y, and Z axes perpendicular to each other. The housing 10 includes a first plate 10a and a second plate 10b arranged opposite each other in the first direction, a third plate 10c and a fourth plate 10d arranged opposite each other in the second direction, and a fifth plate 10e and a sixth plate 10f arranged opposite each other in the third direction. The first plate 10a, second plate 10b, third plate 10c, fourth plate 10d, fifth plate 10e, and sixth plate 10f, when connected, form a smoke collection chamber.
[0051] In some examples, a fan can be installed inside the smoke collection chamber. When the fan is working, it generates negative pressure, which draws away the cooking fumes and directs them through the smoke collection chamber and the aluminum foil duct 30 into the common duct.
[0052] In some examples, the air outlet 101 can be located on the third plate 10c. In the first direction, the distance between the first plate 10a and the second plate 10b is less than the inner diameter of the aluminum foil duct 30. To ensure the airflow of the integrated stove, the air outlet 101 can be set as an elliptical opening, which allows for a larger outer circumference compared to a circular opening.
[0053] See Figure 1 and Figure 2 As shown, the range hood may also include an elastic ring 20. The elastic ring 20 can be fitted onto the outer peripheral wall of the air outlet 101. The aluminum foil duct 30 can be fitted onto the elastic ring 20.
[0054] It should be noted that the elastic ring 20 can deform when subjected to external force. The elastic ring 20 can return to its original shape after the external force is removed.
[0055] The range hood may also include a fastener 40. The fastener 40 is fitted on the outside of the connection between the aluminum foil duct 30 and the elastic ring 20, and clamps the aluminum foil duct 30.
[0056] In some examples, the fastener 40 can be a clamp. The clamp includes an annular steel band 41, a clamp housing 42, and a worm gear 43. The worm gear 43 is disposed within the clamp housing 42 and has threads. The annular steel band 41 has teeth 411. One end of the annular steel band 41 is fixed to the bottom of the clamp housing 42, and the other end of the annular steel band 41 passes through the clamp housing 42 and is located below the worm gear 43, allowing the two ends of the annular steel band 41 to overlap. The teeth 411 on the annular steel band 41 mesh with the threads of the worm gear 43.
[0057] The annular steel belt 41 is sleeved on the outside of the connection between the aluminum foil duct 30 and the elastic ring 20. Through the transmission of the worm gear 43, the annular steel belt 41 clamps and fixes the aluminum foil duct 30.
[0058] The range hood provided in this embodiment of the utility model uses an elastic ring 20 between the aluminum foil duct 30 and the air outlet 101. The aluminum foil duct 30 is supported by the elastic ring 20, which can reduce wrinkles at the connection between the aluminum foil duct 30 and the elastic ring 20, and reduce bending of the aluminum foil duct 30 during the clamping process of the fastener 40. The elastic ring 20 can disperse pressure on the aluminum foil duct 30 during the clamping process of the fastener 40, avoid local stress concentration in the aluminum foil duct 30, thereby reducing damage to the outer skin of the aluminum foil duct 30 during the clamping process of the fastener 40, reducing wear on the aluminum foil duct 30 by the fastener 40, and improving the sealing between the aluminum foil duct 30 and the air outlet 101 during the clamping process of the fastener 40.
[0059] It should be noted that during the clamping process of the fastener 40 on the aluminum foil duct 30, one end of the annular steel strip 41 of the fastener 40 connected to the hoop 42 abuts against the aluminum foil duct 30. It is elastic through the elastic ring 20. When the end of the annular steel strip 41 connected to the hoop 42 squeezes the aluminum foil duct 30, the aluminum foil duct 30 can deform with the elastic ring 20, thereby reducing the damage to the aluminum foil duct 30 caused by the end of the annular steel strip 41 connected to the hoop 42.
[0060] In one possible implementation, see Figure 1 and Figure 2 As shown, the aluminum foil duct 30 includes an aluminum foil tube 31 and a gasket 32. The gasket 32 is connected inside the aluminum foil tube 31 and is connected to the outer peripheral wall of the elastic ring 20. This arrangement results in a smoother surface for the gasket 32 compared to the surface of the aluminum foil tube 31, allowing for a tighter fit between the gasket 32 and the elastic ring 20. This increases friction and improves the seal between the aluminum foil duct 30 and the air outlet 101.
[0061] Among them, the gasket 32 is set at the end where the aluminum foil tube 31 is connected to the air outlet 101.
[0062] In some examples, the gasket 32 can be bonded to the aluminum foil tube 31.
[0063] It should be noted that the materials of washer 32 and elastic ring 20 need to meet the following requirement: the friction force between washer 32 and elastic ring 20 is greater than that between aluminum foil tube 31 and elastic ring 20.
[0064] In some examples, gasket 32 is a PVC gasket and elastic ring 20 is a rubber component. With this configuration, since the static friction coefficient of the PVC gasket is greater than that of the aluminum component, the contact between gasket 32 and elastic ring 20 can increase the friction force and strengthen the fixation between the aluminum foil duct 30 and the air outlet 101.
[0065] In one possible implementation, the inner circumference of the gasket 32 is greater than the outer circumference of the elastic ring 20. This arrangement allows the gasket 32 to be easily fitted over the outer side of the elastic ring 20 during the connection process between the aluminum foil duct 30 and the elastic ring 20, thereby improving the installation efficiency of the aluminum foil duct 30 and the air outlet 101.
[0066] Among them, washer 32 is an annular ring. The inner circumference of washer 32 refers to the circumference of the inner ring of washer 32 in the circumferential direction.
[0067] The elastic ring 20 is a ring. The outer perimeter of the elastic ring 20 refers to the circumference of the outer ring of the elastic ring 20 in the circumferential direction.
[0068] For example, before the elastic ring 20 is connected to the air outlet 101 and before the aluminum foil duct 30 is connected to the elastic ring 20, the gasket 32 of the aluminum foil duct 30 is circular, and the elastic ring 20 is also circular. The inner circumference of the gasket 32 is greater than the outer circumference of the elastic ring 20. It can be understood that the inner diameter of the gasket 32 is greater than the outer diameter of the elastic ring 20.
[0069] For example, the air outlet 101 is an elliptical opening. After the elastic ring 20 is connected to the air outlet 101, the shape of the elastic ring 20 matches the shape of the air outlet 101, that is, the elastic ring 20 is elliptical. The gasket 32 of the aluminum foil duct 30 is fitted on the outside of the elastic ring 20, and the fastener 40 is fitted on the outside of the connection between the aluminum foil duct 30 and the elastic ring 20, and clamps the aluminum foil duct 30, so that the gasket 32 and the elastic ring 20 fit together.
[0070] In one possible implementation, see Figure 3 and Figure 4 As shown, in the direction extending from the central axis of the air outlet 101, i.e., in the Y-axis direction, the size of the gasket 32 is L1, and the size of the elastic ring 20 is L2, where L1 is greater than or equal to L2. This arrangement ensures that after the gasket 32 and elastic ring 20 of the aluminum foil duct 30 are in contact, the gasket 32 covers the elastic ring 20, thereby improving the sealing between the aluminum foil duct 30 and the air outlet 101.
[0071] The air outlet 101 is elliptical in shape. The central axis of the air outlet 101 passes through the center of the air outlet 101.
[0072] In one possible implementation, the inner circumference of the elastic ring 20 is less than or equal to the outer circumference of the air outlet 101. This configuration ensures that when the elastic ring 20 is fitted onto the outer circumferential wall of the air outlet 101, the inner ring of the elastic ring 20 fits snugly against the outer circumferential wall of the air outlet 101, resulting in a stable connection between the elastic ring 20 and the air outlet 101, and strengthening the fixation between the aluminum foil duct 30 and the air outlet 101.
[0073] The inner circumference of the elastic ring 20 refers to the circumference of the inner ring of the elastic ring 20 in the circumferential direction.
[0074] The outer perimeter of the air outlet 101 refers to the circumference of the outer ring of the air outlet 101 in the circumferential direction.
[0075] For example, the air outlet 101 is an elliptical opening. The elastic ring 20 is a rubber component. The inner circumference of the elastic ring 20 is smaller than the outer circumference of the air outlet 101. When the elastic ring 20 is fitted onto the outer circumferential wall of the air outlet 101, the elastic ring 20 undergoes elastic deformation, and the elastic ring 20 fits tightly against the outer circumferential wall of the air outlet 101. Since the static friction coefficient of the rubber component is greater than that of the PVC gasket, the aluminum foil duct 30 contacts the outer circumferential wall of the air outlet 101 through the elastic ring 20, which increases the friction and strengthens the fixation between the aluminum foil duct 30 and the air outlet 101.
[0076] In some examples, gasket 32 is a PVC gasket, and elastic ring 20 is a rubber component. Elastic ring 20 is fitted onto the outer peripheral wall of air outlet 101, gasket 32 of aluminum foil duct 30 is fitted onto the outside of elastic ring 20, and fastener 40 is fitted onto the outside of the connection between aluminum foil duct 30 and elastic ring 20, clamping the aluminum foil duct 30 so that gasket 32 and elastic ring 20 fit together. This installation method eliminates the need for silicone sealant between aluminum foil duct 30 and air outlet 101, reducing the installation difficulty of aluminum foil duct 30 and lowering labor costs.
[0077] In one possible implementation, see Figures 1 to 2 As shown, at least one limiting rib 102 is provided on the outer peripheral wall of the air outlet 101. The limiting rib 102 is located on the side away from the smoke collection chamber at the connection between the elastic ring 20 and the aluminum foil duct 30. With this arrangement, the limiting rib 102 can block the elastic ring 20, preventing it from falling off the outer peripheral wall of the air outlet 101, and strengthening the fixation between the aluminum foil duct 30 and the air outlet 101.
[0078] The limiting rib 102 can be provided on the outer peripheral wall of the air outlet 101, protruding in a direction away from the center of the air outlet 101.
[0079] In some examples, multiple limiting ribs 102 are provided on the outer peripheral wall of the air outlet 101, and the multiple limiting ribs 102 are provided at intervals along the circumference of the air outlet 101. In other embodiments, a single limiting rib 102 may be provided on the outer peripheral wall of the air outlet 101, and the limiting rib 102 is provided around the entire circumference of the air outlet 101.
[0080] In some examples, along the extension direction of the central axis of the air outlet 101, i.e., the Y-axis direction, the two sides of the elastic ring 20 abut against the limiting rib 102 and the housing 10, respectively. With this configuration, the limiting rib 102 can limit the elastic ring 20 along the extension direction of the central axis of the air outlet 101, ensuring the elastic ring 20 remains stable on the outer peripheral wall of the air outlet 101, thereby enhancing the stability between the aluminum foil duct 30 and the air outlet 101.
[0081] This utility model embodiment provides an integrated stove, including a range hood.
[0082] The range hood in this embodiment has the same structure as the range hood provided in any of the above embodiments and can bring the same or similar technical effects. It will not be described in detail here. For details, please refer to the description of the above embodiments.
[0083] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
