Description

Technical Field

[0001] This utility model relates to the field of kitchen appliance technology, and in particular to a heat-insulating and noise-reducing component and an integrated stove. Background Technology

[0002] An integrated cooktop is a device that integrates a range hood, gas stove, steam oven, and other kitchen appliances into one unit. It has the advantages of high integration, small footprint, and ease of use.

[0003] Existing integrated cooktops typically include a housing, a steam oven located at the front of the housing, an air duct assembly located at the rear of the housing, a gas stove located at the top of the housing, and a range hood installed behind the gas stove. The air duct assembly includes an air box installed on the back of the steam oven and a fan located inside the air box, with the fan inlet connected to the smoke collection chamber of the range hood.

[0004] Existing gas stoves, with their air duct components and steam ovens arranged side-by-side in the front-to-back direction, are limited by the size of the casing. This makes it difficult to adequately accommodate the size requirements of the fan and steam oven while maintaining the same front-to-back dimensions of the integrated stove. Consequently, existing integrated stoves generally suffer from insufficient airflow due to inadequate fan size or small steam oven capacity. Furthermore, to meet the noise reduction requirements during fan operation, noise reduction panels and components need to be installed on the front side of the air box back panel. This further compresses the rear space inside the casing, thus affecting the selection of the steam oven and fan. Utility Model Content

[0005] The purpose of this utility model is to provide a heat insulation and noise reduction component and an integrated stove, which can improve the compactness of the internal structure of the integrated stove and increase the flexibility of selecting fans and cooking modules.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] A heat insulation and noise reduction component is used in an integrated stove. It includes a heat insulation component, a partition component, a noise reduction component, and an oil-separating component stacked in sequence. The oil-separating component has oil-separating and noise-reducing functions, and the partition component is used to isolate oil stains.

[0014] And / or, the insulation components, partition components, noise reduction components and oil-blocking components are bonded together in sequence.

[0015] An integrated stove includes a chassis, a cooking module disposed on the front side inside the chassis, and an air duct assembly disposed on the rear side inside the chassis. The air duct assembly has a front air duct panel spaced apart on the rear side of the cooking module. It also includes the aforementioned heat insulation and noise reduction component, which is sandwiched between the front air duct panel and the rear side of the cooking module. The heat insulation component is located on the side of the separating component facing the cooking module. The front air duct panel has multiple noise reduction holes, and the heat insulation and noise reduction component covers the noise reduction holes.

[0016] As an optional technical solution for integrated stoves, the air duct assembly also includes a volute, an impeller, and a drive motor. The front panel of the air duct has a volute end plate. The volute includes an air inlet end plate and a side panel. The air inlet end plate is opposite to and spaced apart from the volute end plate. The side panel is connected between the volute end plate and the air inlet end plate. The air inlet end plate has an air inlet. The side panel, the air inlet end plate, and the volute end plate together form an air cavity and an air outlet. Both the air inlet and the air outlet are connected to the air cavity.

[0017] As an optional technical solution for integrated stoves, the cooking module includes an inner liner with a cooking cavity, the rear side of which is attached to the front side of the heat insulation and noise reduction component;

[0018] And / or, the distance between the rear side of the cooking module and the front panel of the air duct in the front-rear direction is less than the thickness of the insulation and noise reduction component when it is not compressed and deformed.

[0019] As an optional technical solution for integrated stoves, the projection of the inner liner on the front side of the insulation and noise reduction component is located inside the insulation and noise reduction component.

[0020] As an optional technical solution for integrated stoves, the heat insulation and noise reduction components are bonded to the front side of the air duct front panel.

[0021] The beneficial effects of this utility model are:

[0022] The heat insulation and noise reduction component provided by this utility model, by setting up heat insulation components and noise reduction components, allows the heat insulation component to cooperate with the rear side of the cooking module in the integrated stove to achieve the heat insulation function of the cooking module. The noise reduction component can cooperate with the front panel of the air duct with noise reduction holes to achieve noise reduction and sound absorption during the oil fume extraction process, reducing the noise of the integrated stove during operation. By setting up an oil-separating component, at least part of the oil fume can be blocked from flowing into the noise reduction component, better ensuring the noise reduction effect of the noise reduction component. By setting up a separating component, oil stains can be blocked from flowing into the heat insulation component, thereby ensuring the heat insulation effectiveness of the heat insulation component and reducing the cleaning difficulty of the integrated stove. Furthermore, by stacking the heat insulation component, separating component, and noise reduction component in sequence, the space occupied by the heat insulation and noise reduction structure inside the integrated stove can be reduced while achieving the heat insulation and noise reduction functions, thereby maximizing the internal space of the integrated stove.

[0023] The integrated stove provided by this utility model, by adopting the above-mentioned heat preservation and noise reduction components, can reduce the footprint of the internal heat preservation and noise reduction structures of the integrated stove while achieving the heat preservation and noise reduction functions. This allows for the integration of the internal space of the stove, which is conducive to the use of a larger air volume fan or a larger capacity cooking module, thereby improving the compactness of the internal structure of the integrated stove and enhancing the user experience.

It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0038] This embodiment provides an integrated stove that can improve the compactness of the internal structure of the integrated stove, reduce the noise during operation, and enhance the user experience of the integrated stove.

[0039] like Figure 1 and Figure 2 As shown, in this embodiment, the integrated stove includes a housing 400, a cooktop 500, a range hood module, and a cooking module 300. The cooktop 500 is installed at the top of the housing 400. The range hood module includes a range hood head 600 and a duct assembly 100. The range hood head 600 is installed at the top of the housing 400 and located behind the cooktop 500. The range hood head 600 has a connected smoke inlet and a smoke collection chamber 601. The duct assembly 100 has a duct cavity and a fan located within the duct cavity. The fan inlet, duct cavity, and smoke collection chamber 601 are sequentially connected, allowing the fan to expel cooking fumes sequentially through the smoke inlet, smoke collection chamber 601, duct cavity, and fan to the external environment or a public flue. The cooking module 300 is installed inside the housing 400 and located in front of the duct assembly 100. The cooking module 300 can be, but is not limited to, any specific cooking module.

[0040] like Figures 2 to 5 As shown, the front panel 1 of the air duct assembly 100 is spaced apart from the rear side of the cooking module 300 to form an installation gap. In this embodiment, the integrated stove also includes a heat insulation and noise reduction component 200. The heat insulation and noise reduction component 200 includes a heat insulation component 202, a separating component 204, a noise reduction component 201, and an oil-blocking component 203 stacked sequentially. The oil-blocking component 203 has an oil-blocking and noise reduction function, and the separating component 204 is used to isolate oil stains. The heat insulation and noise reduction component 200 is installed between the front panel 1 of the air duct and the rear side of the cooking module 300, and the heat insulation component 202 is located on the side of the separating component 204 facing the cooking module 300. The rear side of the cooking module 300 is pressed against the heat insulation and noise reduction component 200. The front panel 1 of the air duct is provided with a plurality of noise reduction holes 111, and the heat insulation and noise reduction component 200 covers the noise reduction holes 111.

[0041] The heat insulation and noise reduction component 200 provided in this embodiment, by setting up a heat insulation component 202 and a noise reduction component 201, allows the heat insulation component 202 to cooperate with the rear side of the cooking module 300 in the integrated stove to achieve the heat insulation function of the cooking module 300. The noise reduction component 201 can cooperate with the air duct front panel 1 with noise reduction holes 111 to achieve noise reduction and sound absorption during the fume extraction process, reducing the noise of the integrated stove during operation. By setting up an oil-separating component 203, at least part of the oil fumes can be blocked from flowing into the noise reduction component 201, better ensuring the noise reduction effect of the noise reduction component 201. The separator 204 can prevent oil stains from flowing into the insulation component 202, thereby ensuring the insulation effectiveness of the insulation component 202 and reducing the difficulty of cleaning the integrated stove. Furthermore, by stacking the insulation component 202, the separator 204, and the noise reduction component 201 in sequence, the space occupied by the insulation and noise reduction structures inside the integrated stove can be reduced while achieving the insulation and noise reduction functions. This frees up space, making it easier to use a larger air volume fan or a larger capacity cooking module 300, improving the compactness of the internal structure of the integrated stove and enhancing the user experience.

[0042] The thermal insulation and noise reduction component 200 also includes a heat-conducting layer 205, which is stacked on the side of the thermal insulation component 202 away from the separating component 204; that is, the heat-conducting layer 205 is provided on the front side of the thermal insulation component 202. The heat-conducting layer 205 can enhance the heat conduction between the thermal insulation component 202 and the inner liner 301, thereby enhancing the thermal insulation effect of the thermal insulation component 202 on the inner liner 301. The heat-conducting layer 205 can be, but is not limited to, a structure capable of heat conduction, such as aluminum foil insulation cloth.

[0043] In this embodiment, the heat insulation component 202 is heat insulation cotton, and the noise reduction component 201 is noise reduction and sound-absorbing cotton. The structure is simple, the cost is low, and the noise reduction and heat insulation effects are good. In other embodiments, the heat insulation component 202 can also adopt other existing structures that can achieve heat insulation, such as heat insulation felt, and the noise reduction component 201 can also adopt existing structures that can achieve noise reduction.

[0044] In this embodiment, the thickness of the heat insulation component 202, the thickness of the noise reduction component 201, and the thickness of the partition component 204 gradually decrease. By setting relatively thick heat insulation component 202 and noise reduction component 201, the heat insulation effect of the cooking module 300 and the noise reduction effect during the fume extraction process can be guaranteed, while using relatively thin partition component 204 helps to reduce the overall thickness of the heat insulation and noise reduction component 200, thereby reducing the footprint.

[0045] In this embodiment, the thicknesses of the separating component 204 and the heat-conducting layer 205 are both greater than or equal to 0.1 mm and less than or equal to 0.5 mm to avoid increasing the thickness of the insulation and noise reduction component 200 due to excessive thickness of the separating component 204 and the heat-conducting layer 205. The thickness of the insulation component 202 is 1 mm to 5 mm to ensure the insulation and noise reduction effect of the insulation component 202. The thickness of the insulation component 202 can be, but is not limited to, 1 mm, 1.5 mm, 2 mm, 2.5 mm, 3 mm, 3.5 mm, 4 mm, 4.5 mm, and 5 mm.

[0046] To improve the structural stability of the thermal insulation and noise reduction component 200, the thermal insulation component 202, the partition component 204, the noise reduction component 201, and the oil-separating component 203 are bonded together in sequence. This ensures the structural stability of the thermal insulation and noise reduction component 200 while reducing the connection difficulty and improving processing convenience. Furthermore, the heat-conducting layer 205 is bonded to the thermal insulation component 202.

[0047] The shape of the heat insulation component 202 is preferably rectangular, which is easy to process. The shapes of the separator 204, the heat-conducting layer 205, the noise reduction component 201 and the oil-separating component 203 are all consistent with the shape of the heat insulation component 202, so that the stacked heat insulation and noise reduction component 200 has a regular rectangular structure, which is easy to process and use.

[0048] In this embodiment, the cooking module 300 includes an inner pot 301, the rear side of which abuts against the heat insulation and noise reduction component 200. By directly abutting the rear side of the inner pot 301 against the heat insulation and noise reduction component 200, a rear shell structure is not required on the cooking module 300, further saving space and improving space utilization, thereby facilitating an increase in the volume of the cooking cavity. The orthographic projection of the inner pot 301 onto the front side of the heat insulation and noise reduction component 200 is located inside the heat insulation and noise reduction component 200, ensuring that the rear side of the inner pot 301 is in contact with the heat insulation and noise reduction component 200, thus better guaranteeing the heat insulation and noise reduction effect of the inner pot 301.

[0049] Furthermore, the distance between the rear side of the cooking module 300 and the front panel 1 of the air duct in the front-back direction is less than the thickness of the heat insulation and noise reduction component 200 when it is not compressed and deformed. As a result, when the integrated stove is assembled, the cooking module 300 can press the heat insulation and noise reduction component 200 backward, so that the rear side of the cooking module 300 can be in close contact with the heat insulation and noise reduction component 200, which helps to ensure the heat insulation effect of the heat insulation and noise reduction component 200 on the cooking module 300.

[0050] The distance between the rear side of the cooking module 300 and the front panel 1 of the air duct is d, and the thickness of the heat insulation and noise reduction component 200 is t, where d = 0.7t ~ 0.95t.

[0051] In this embodiment, the thermal insulation and noise reduction component 200 is bonded to the front side of the air duct front panel 1 to ensure the stability and reliability of the installation of the thermal insulation and noise reduction component 200. In other embodiments, the thermal insulation and noise reduction component 200 can also be fastened to the air duct front panel 1 with fasteners.

[0052] The air duct assembly 100 includes two air duct side plates 5 that are arranged opposite to each other and spaced apart in the left and right direction. The front ends of the two air duct side plates 5 are connected to the air duct front plate 1 and the rear ends abut against the back plate 401 of the chassis 400. The lower ends abut against the bottom plate 402 of the chassis 400, so that the air duct front plate 1, back plate 401, bottom plate 402 and the two air duct side plates 5 together form an air duct cavity.

[0053] like Figure 2 and Figure 6 As shown, the fan is located in the air duct cavity. The fan includes a volute 2, an impeller 3, and a drive motor 4. The air duct front plate 1 has a volute end plate portion 11. The volute 2 includes an air inlet end plate 22 and a side plate 21. The air inlet end plate 22 is opposite to and spaced apart from the volute end plate portion 11. The side plate 21 is connected between the volute end plate portion 11 and the air inlet end plate 22. The air inlet end plate 22 has an air inlet. The side plate 21, the air inlet end plate 22, and the volute end plate portion 11 together form an air cavity and an air outlet. Both the air inlet and the air outlet are connected to the air cavity. The volute end plate portion 11 has a noise reduction hole 111. The impeller 3 is rotatably installed in the air cavity. The drive motor 4 is installed on the air duct front plate 1 and connected to the impeller 3. This configuration allows the front panel 1 of the air duct to form the rear panel structure of the volute 2, thereby integrating the rear panel of the volute and the front panel 1 of the air duct. This further reduces the footprint of the air duct assembly 100 and improves the structural compactness of the air duct assembly 100.

[0054] Noise reduction holes 111 are arranged approximately evenly on the end plates of the volute housing to improve the noise reduction effect. The noise reduction holes 111 are preferably circular holes to facilitate their machining. The diameter of the noise reduction holes 111 is D, preferably 1mm ≤ D ≤ 3.5mm. The diameter D of the noise reduction holes 111 can be, but is not limited to, 1mm, 1.2mm, 1.4mm, 1.6mm, 1.8mm, 2mm, 2.2mm, 2.4mm, 2.6mm, 2.8mm, 3mm, 3.2mm, 3.5mm, etc.

[0055] The noise reduction holes 111 are preferably arranged in multiple rows along the vertical direction, with each row including multiple noise reduction holes 111 spaced apart. The distance between two adjacent noise reduction holes 111 located in the same row and on the same side of the motor mounting part 12 is d1, preferably 5mm ≤ d1 ≤ 20mm. Further, the distance between two adjacent noise reduction holes 111 in the vertical direction is d2, 5mm ≤ d2 ≤ 20mm. Both d1 and d2 can be, but are not limited to, 5mm, 6mm, 7mm, 8mm, 10mm, 13mm, 15mm, 17mm, 20mm, etc.

[0056] The front plate 1 of the air duct is recessed rearward to form a volute end plate portion 11. The portion of the front plate 1 surrounding the outer side of the volute end plate portion 11 is the air duct plate portion 13, which causes the volute end plate portion 11 to bulge rearward relative to the air duct plate portion 13. The side plate 21 is fitted onto the outer side of the volute end plate portion 11 and abuts against the air duct plate portion 13 to achieve the assembly positioning and limiting of the side plate 21 and the front plate 1 of the air duct, ensuring the assembly reliability of the side plate 21 and the front plate 1 of the air duct, and thus ensuring the assembly reliability of the volute 2.

[0057] The volute 2 also includes an adapter 23 connected to the air outlet. The projection of the adapter 23 on the front panel 1 of the air duct is located inside the front panel 1 of the air duct. The adapter 23 facilitates the connection between the volute 2 and the exhaust pipe 6.

[0058] To improve the ease of installation of the drive motor 4, the volute end plate 11 is recessed rearward to form a motor mounting part 12. A motor mounting hole 121 is provided on the motor mounting part 12, through which the drive motor 4 passes. The motor housing of the drive motor 4 is fixedly mounted on the motor mounting part 12, thus enabling the assembly of the drive motor 4 on the front panel 1 of the air duct. Simultaneously, the recessed motor mounting part 12 provides sufficient space for the installation of the drive motor 4, preventing interference between the drive motor 4 and the front insulation and noise reduction component 200. Preferably, the motor mounting part 12 has a frustum-shaped structure, with the centerline of the frustum-shaped structure collinear with the axis of the impeller 3.

[0059] It is worth noting that the specific mounting structure of the drive motor 4 on the motor mounting part 12 can be set with reference to the existing mounting structure of the drive motor 4, and this utility model does not limit or elaborate on it. The connection structure between the drive motor 4 and the impeller 3 and the specific structure of the impeller 3 can also be set with reference to the prior art, which is not the focus of this utility model and will not be elaborated here.

[0060] A wiring hole 131 is provided on the front panel 1 of the air duct. The connecting wire of the drive motor 4 extends out of the air duct cavity through the wiring hole 131 to electrically connect with the control module of the integrated stove, thereby improving the safety and convenience of wiring. The wiring hole 131 is preferably an elongated hole to avoid scratches and improve the convenience of wiring.

[0061] The specific structure of the cooking module 300 can refer to the specific structure of the existing embedded cooking module, and the specific installation structure of the cooking module 300 inside the chassis 400 can adopt the structure in the existing technology. This is not the focus of the improvement of this utility model, and will not be limited or elaborated here.

[0062] like Figure 2 As shown, to facilitate the discharge of oil and condensate, an oil collection trough 4021 is formed by a downward indentation on the bottom plate 402 of the chassis 400. The oil collection trough 4021 is located below the air duct cavity. An oil leakage hole is provided at the bottom of the side panel 21 of the volute 2, located above the oil collection trough 4021. This allows oil, condensate, or cleaning water in the air duct cavity to flow into the oil collection trough 4021. An oil drain port 4022 is provided at the bottom of the oil collection trough 4021. An oil cup 700 is installed at the bottom of the chassis 400, with the oil drain port 4022 located above the oil cup 700, so that the oil collected in the oil collection trough 4021 can flow downward into the oil cup 700 through the oil drain port 4022.

[0063] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
