Description

Technical Field

[0001] This invention relates to the field of kitchen appliance technology, specifically to a split-type integrated stove and its air duct structure technology. Background Technology

[0002] Split-type integrated cooktops effectively isolate the main noise source by placing the fan externally (usually outdoors or in a shared flue), significantly improving the kitchen noise environment. However, their actual installation faces significant challenges in terms of versatility.

[0003] Because of significant differences in building wall structures, flue locations, and interior layouts, the height of the smoke exhaust duct connecting the indoor unit and the outdoor fan is non-standard. Existing solutions mostly use flexible pipes for on-site adjustments. Although these pipes have a certain degree of deformation capability, they are prone to collapse and deformation when subjected to complex bends or laid over long distances, resulting in a sharp increase in wind resistance and a decrease in smoke exhaust efficiency. At the same time, their joint sealing is poor and their aging resistance is weak, posing a risk of smoke leakage, oil accumulation, and even detachment with long-term use.

[0004] Therefore, relying solely on flexible pipes cannot balance installation adaptability and system reliability. The lack of modular air duct structure still severely restricts the large-scale application and user experience of split-type integrated stoves.

[0005] In summary, existing split-type integrated stove air duct systems still suffer from problems such as difficulty in balancing flexibility, sealing, and aerodynamic performance when adapting to diverse installation environments. Summary of the Invention

[0006] The purpose of this section is to outline some aspects of the embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the invention.

[0007] In view of the problems mentioned above and / or existing fingerprint attendance machines, the present invention is proposed.

[0008] Therefore, this application proposes a split-type integrated stove and its air duct structure, which aims to achieve highly adaptable installation through modular design and selectable air outlets.

[0009] To address the aforementioned technical problems, according to one aspect of the present invention, the present invention provides the following technical solution: A split-type integrated stove's air duct structure includes: The main unit casing has an internal ventilation channel; The main unit housing is provided with at least two preset exhaust ports that can be selectively opened, which are used to selectively guide the oil fumes in the exhaust duct to different exhaust directions.

[0010] As a preferred embodiment of the air duct structure of the split-type integrated stove described in this invention, the preset exhaust interface includes a rear outlet of the main body located on the back of the main unit housing, or a guide interface located at the bottom of the main unit housing.

[0011] As a preferred embodiment of the air duct structure of the split-type integrated stove described in this invention, a knockable micro-connection structure is provided at the rear outlet of the main body or the air guide interface. The knockable micro-connection structure is integrally stamped with the surrounding plate through several small connecting ribs.

[0012] As a preferred embodiment of the air duct structure of the split-type integrated stove described in this invention, the main unit housing includes a front guide plate and a rear sealing plate, and the exhaust channel extends longitudinally between the front guide plate and the rear sealing plate.

[0013] As a preferred embodiment of the air duct structure of the split-type integrated stove described in this invention, the air duct structure further includes a lower extension air guide module, the upper end of which is detachably connected to the air guide interface, and the rear end of which is provided with a cabinet rear outlet for connecting to an external exhaust pipe.

[0014] As a preferred embodiment of the air duct structure of the split-type integrated stove described in this invention, the lower extension air guide module has an inverted trapezoidal structure that is wider at the top and narrower at the bottom, and is an independently prefabricated sealed module.

[0015] As a preferred embodiment of the air duct structure of the split-type integrated stove described in this invention, the air duct structure further includes a reversing extension section and a side exhaust sealing section. The upper end of the reversing extension section is connected to the flow guide interface, and its lower end turns to the horizontal direction and is connected to the side exhaust sealing section. The end of the side exhaust sealing section is provided with a side exhaust port for connecting to an external exhaust pipe.

[0016] As a preferred embodiment of the air duct structure of the split-type integrated stove described in this invention, the air duct structure further includes an adjustable-length transition connection section, which is connected between the reversing extension section and the side exhaust sealing section, and both the reversing extension section and the transition connection section adopt a flat and narrow channel structure.

[0017] The present invention also provides a split-type integrated stove, including the above-mentioned air duct structure and cabinet body, which is disposed below the main unit housing; External fans are installed outdoors or in public smoke ducts; The exhaust outlet of the air duct structure is connected to the external fan via an exhaust connection pipe.

[0018] Compared with existing technologies, the advantages of this invention are as follows: By setting multiple selectable pre-installed exhaust ports on the main unit housing, and cooperating with independent prefabricated modules such as the downward-extending air guide module, the reversing extension section, and the side exhaust sealing section, the exhaust method can be flexibly selected according to different building flue locations, wall structures, and cabinet layouts, including rear exhaust, cabinet rear exhaust, or cabinet side exhaust, significantly improving the product's adaptability to different kitchen installation environments. Through selectable straight or shortest path exhaust outlets, the exhaust connection pipe can be directly connected to the exhaust outlet, avoiding the problem of increased wind resistance caused by on-site bending and collapse of traditional flexible pipes, effectively reducing airflow resistance, improving smoke extraction efficiency, and enhancing long-term stability.

Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that the embodiments described below are only some embodiments of this application, and not all of them. Based on the embodiments in this application, all other equivalent embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. Example 1

[0021] Please refer to Figures 1 to 4This embodiment provides a duct structure for a split-type integrated stove. The duct structure includes a main unit housing 100, which has an exhaust channel formed inside. Specifically, the front end of the main unit housing 100 has a smoke collection chamber 101, which is enclosed by a side panel 11, a top cover plate 12, and a rear sealing plate 13. A front guide plate 14 is disposed at the front end of the rear sealing plate 13 and maintains a distance from it; an oil fume filter 2 is installed on its upper end, and a bottom sealing plate 15 is provided on its lower end. Thus, a longitudinally extending exhaust channel is formed between the front guide plate 14 and the rear sealing plate 13, which communicates with the smoke collection chamber 101 and further connects to multiple preset exhaust ports.

[0022] In this embodiment, the main unit housing 100 is provided with at least two selectable pre-set exhaust ports for selectively guiding the oil fumes in the exhaust duct to different exhaust directions. Specifically, please refer to... Figure 4 The pre-installed exhaust port includes a rear outlet 131 located on the back of the main unit housing 100. This rear outlet 131 is not a direct opening, but rather integrally stamped with the rear sealing plate 13 using several small connecting ribs, forming a removable micro-connection structure. During factory pre-installation, this area remains sealed to ensure the strength and appearance integrity of the housing; during on-site installation, the user or installer can easily remove the connecting ribs by gently tapping with a tool, depending on the location of the flue, exposing a standard-sized circular or rectangular opening as the exhaust outlet. This design retains the versatility of the main unit housing while avoiding the risks of burrs, deformation, or poor sealing caused by on-site cutting.

[0023] As an alternative, the pre-installed exhaust port also includes a guide port 151 located at the bottom of the main unit housing 100 (see [link]). Figure 5 , Figure 6 The flow inlet 151 can also be a knock-out micro-connection structure or a removable cover with a sealing ring to keep it closed when not in use.

[0024] With the above structure, the air duct structure of this embodiment can switch between two basic directions of back exhaust or bottom exhaust without adding any additional modules. Example 2

[0025] Please refer to Figure 5 and Figure 6 In some kitchen environments, due to the low position of the building's flue or the limitations of the cabinet structure, it is impossible to directly exhaust air from the back of the main unit casing. Therefore, this embodiment, based on Embodiment 1, further includes a downward-extending air guide module 4.

[0026] The upper end of the downward-extended air guide module 4 is detachably connected to the air guide interface 151 at the bottom of the main unit housing 100. The downward-extended air guide module 4 has an inverted trapezoidal structure, with its upper end matching the air guide interface 151 and its lower end fitting into the inner space of the cabinet back panel. The rear end of the module 4 is provided with a cabinet rear outlet 41, which serves as an exhaust outlet, leading to the external fan 200 via an exhaust connection pipe 400. Since the downward-extended air guide module 4 is an independent prefabricated component, it can complete the sealing test before leaving the factory, requiring only plug-in fixing on site without on-site processing, greatly simplifying the installation process. At the same time, since the air guide interface 151 and the main unit rear outlet 131 are alternatives to each other, different exhaust directions can be achieved by replacing the lower module on the same main unit housing. Example 3

[0027] Please refer to Figure 7 When the kitchen exhaust duct is located on the side wall and cannot exhaust from the back, this embodiment provides an alternative exhaust solution. The duct structure also includes a reversing extension section 5 and a side exhaust sealing section 7. The upper end of the reversing extension section 5 is connected to the air guide interface 151 at the bottom of the main unit housing 100, guiding the airflow downward and turning it horizontally. The lower end of the reversing extension section 5 is connected to the side exhaust sealing section 7, which extends along the inner side wall of the cabinet body 300, and its end is provided with a side exhaust port 71. An oil collection box is provided inside the side exhaust sealing section 7 to store the extracted oil. The side exhaust sealing section 7 serves as an exhaust outlet, passing through the side panel and connecting to the exhaust connection pipe 400.

[0028] To accommodate different cabinet depths, this embodiment also includes an adjustable transition section 6 between the reversing extension section 5 and the side sealing section 7. This transition section 6 can be a telescopic sleeve or a multi-section splicing structure to achieve flexible adjustment of its horizontal length. It is worth noting that both the reversing extension section 5 and the transition section 6 adopt a flat and narrow channel structure, meaning their depth (consistent with the depth of the cabinet body) is much smaller than their longitudinal dimension (height), thus achieving airflow redirection within the limited internal space of the cabinet without encroaching on storage space.

[0029] Through the modular combination described above, the duct structure of this embodiment can select the direction of the side exhaust port 71 (left or right) according to the actual flue location, thereby maximizing installation flexibility. Example 4

[0030] Please refer to Figure 1This embodiment provides a split-type integrated stove, including a main unit housing 100, a cabinet body 300 disposed at the lower end of the main unit housing 100, an external fan 200 located outside the building wall 500, and the air duct structure described in any of the above embodiments. The exhaust outlet of the air duct structure is connected to the external fan 200 through an exhaust connecting pipe 400. The smoke inlet of the fan 200 can be located on one side close to the building wall 500, or on the top or front and rear sides of the fan 200, thereby improving the adaptability of the fan 200 installation.

[0031] In actual installation, the exhaust outlet can be optionally located at the back of the main unit housing 100 (e.g., Figure 4 The rear outlet 131 of the main body shown), the back of the cabinet body 300 (as shown) Figure 5 , Figure 6 The cabinet rear outlet 41 shown), or the side of the cabinet body 300 (as shown) Figure 7 (Side exhaust port 71 shown). On-site installers can select the corresponding preset interface and install the corresponding module according to the actual wall flue location and cabinet layout to achieve the shortest and straightest exhaust path, avoiding the problems of flexible hose bending and collapse and increased wind resistance.

[0032] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the invention. In particular, as long as there is no structural conflict, the features in the disclosed embodiments can be combined with each other in any manner. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
