Description

Technical Field

[0001] This utility model relates to the technical field of integrated stoves, and more specifically, it relates to an air inlet structure and an integrated stove having the same structure. Background Technology

[0002] An integrated cooktop is a kitchen appliance that combines multiple functions such as a range hood, gas stove, disinfection cabinet, and storage cabinet. It saves space, is easy to operate, and has the advantages of being environmentally friendly and energy-saving. With the diversification of products, integrated cooktops combining induction cookers and range hoods have also appeared on the market.

[0003] There are various types of integrated cooktops with induction cooktops and range hoods, such as top-mounted, side-mounted, and downdraft types. Among them, downdraft integrated cooktops, due to their lower air inlet position, often suffer from insufficient air pressure, making it difficult to quickly and effectively remove the large amount of oil fumes generated during cooking. Their smoke extraction efficiency fails to meet user needs, affecting the user's cooking experience. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an air inlet structure and an integrated stove with the same structure, which has the advantages of enhancing air intake negative pressure and improving smoke extraction efficiency.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: an air inlet structure, including an air inlet grille base and an air inlet grille, wherein the air inlet grille base is a hollow structure with an air inlet end cross section larger than the air outlet end cross section, and the air inlet grille is installed on the air inlet grille base.

[0006] In one embodiment, the outer wall of the air inlet grille is provided with a plurality of striped reinforcing ribs spaced apart.

[0007] In one embodiment, a flange is horizontally wound around the outer wall of the air inlet grille, and the flange is disposed at the air inlet end of the air inlet grille.

[0008] In one embodiment, the inner wall of the air intake grille has a raised edge on the side near its air intake end, and the air intake grille is detachably snapped onto the raised edge.

[0009] In one embodiment, the air inlet grille includes a grille baffle and a filter screen, the filter screen being snapped onto the raised edge, and the grille baffle being stacked on the filter screen.

[0010] In one embodiment, the air inlet structure is made of plastic, and its inner walls are all designed with a rough surface.

[0011] Another technical solution adopted by this utility model is to provide an integrated stove, including a stove body, an operating platform installed on the stove body, and an air duct system installed in the stove body, and also includes an air inlet structure.

[0012] In one embodiment, the operating platform is provided with a through opening, the air inlet end of the air inlet structure is connected to the opening, and the air outlet end of the air inlet structure is connected to the air inlet end of the air duct system.

[0013] The aforementioned air inlet structure and integrated cooktop incorporating it have the following beneficial effects:

[0014] Firstly, through the cooperation of the air inlet grille and the air inlet grille, the oil fume is efficiently guided and filtered, while the negative pressure of the air inlet is enhanced, the smoke extraction efficiency is improved, and the user's demand for efficient smoke extraction is met.

[0015] Secondly, the air inlet structure is made of plastic and has reinforcing ribs, which increases the stability and durability of the structure. At the same time, the rough surface design of the inner wall helps to reduce the sound resonance generated when the air flows, effectively reducing noise and providing a quieter cooking environment.

[0020] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0021] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0022] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "a plurality of" means at least two, unless otherwise explicitly specified.

[0023] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a connection that allows communication between them; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0024] In this utility model, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0025] Embodiment 1 of this utility model is an air inlet structure, such as... Figure 1 and Figure 2 As shown, it includes an air inlet grille 1 and an air inlet grille 2. The air inlet grille 1 is a hollow structure with an air inlet cross-section larger than the air outlet cross-section, and the air inlet grille 2 is installed on the air inlet grille 1.

[0026] In this embodiment, the air inlet grille 1 is the main body of the entire air inlet structure. Its large cross-section design at the air inlet end is designed to reduce air resistance and increase air volume. At the same time, by utilizing the gradually decreasing cross-section, it guides the airflow to accelerate and enhances the negative pressure of the air inlet, thereby improving the overall smoke extraction efficiency. The air inlet grille 2 is a mesh plate that is set together with the air inlet grille 1. As the first line of defense for the air inlet, it can not only effectively block large particles of impurities from entering, but also homogenize the airflow to a certain extent, reduce the generation of eddies, and protect the cleanliness and smoothness of the internal air duct system 8.

[0027] This utility model achieves efficient air guidance and filtration through the cooperation of air inlet grille 1 and air inlet grille 2, while enhancing the negative pressure of air intake and improving smoke extraction efficiency, thus meeting users' needs for efficient smoke extraction.

[0028] Furthermore, such as Figure 1 and Figure 2 As shown, the outer wall of the air inlet grille 1 is provided with multiple striped reinforcing ribs 3 at intervals.

[0029] Specifically, multiple striped reinforcing ribs 3 are evenly arranged along the airflow direction to disperse and resist external forces such as airflow impact and equipment vibration, thereby protecting the air inlet grille 1 from damage.

[0030] Furthermore, such as Figure 1 and Figure 2 As shown, a flange 4 is horizontally wound around the outer wall of the air inlet grille 1, and the flange 4 is located at the air inlet end of the air inlet grille 1.

[0031] Specifically, the flange 4 not only further increases the structural strength of the air inlet grille 1, but also provides additional positioning points, making it easier for the air inlet grille 1 to connect with other structures through the flange 4, while restricting the movement of the air inlet grille 1.

[0032] Furthermore, such as Figure 2 As shown, the inner wall of the air intake grille 1 has a raised edge 5 on the side near its air intake end, and the air intake grille 2 is detachably attached to the raised edge 5.

[0033] Specifically, the function of the raised edge 5 is to provide a stable slot, allowing users to easily install and remove the air inlet grille 2, facilitating daily cleaning and maintenance, ensuring the cleanliness and unobstructed flow of the air inlet structure, and thus maintaining smoke extraction efficiency.

[0034] Furthermore, such as Figure 2 As shown, the air inlet grille 2 includes a grille baffle 201 and a filter screen 202. The filter screen 202 is clipped onto the protruding edge 5, and the grille baffle 201 is stacked on the filter screen 202.

[0035] Specifically, the grille baffle 201 is a grid-like plate composed of crisscrossing grids, which can effectively prevent the entry of larger foreign objects and protect the internal mechanical parts from damage. It also makes it easy for users to remove and clean the grille baffle 201 when needed, ensuring that the ventilation duct is unobstructed. The filter screen 202 is the same size as the grille baffle 201 and is a grid-like plate composed of multiple rectangles, used to intercept small particles in the oil fumes.

[0036] Furthermore, the air inlet structure is made of plastic, and its inner walls are all designed with a rough surface.

[0037] Specifically, the plastic material can reduce the overall weight of the air inlet structure, while the rough surface design of the inner wall helps to reduce the sound resonance generated when the air flows, effectively reducing noise and providing a quieter cooking environment.

[0038] Embodiment two of this utility model is an integrated stove, such as... Figure 3 As shown, it includes a stove body 6, an operating platform 7 installed on the stove body 6, and an air duct system 8 installed inside the stove body 6, as well as an air inlet structure.

[0039] In this embodiment, the cooktop 6 is the basic part of the integrated cooktop, providing the main space for cooking; the operating platform 7 is equipped with various control buttons or touch-sensitive keys to adjust the fire level, turn on the range hood, etc.; the air duct system 8 is responsible for exhausting the oil fumes and heat generated during cooking from the kitchen to keep the indoor air clean; the air inlet structure is an important component of the integrated cooktop, used to introduce air to help extract oil fumes.

[0040] Furthermore, such as Figure 3 As shown, the operating platform 7 is provided with a through opening 701. The air inlet end of the air inlet structure is connected to the opening 701, and the air outlet end of the air inlet structure is connected to the air inlet end of the air duct system 8.

[0041] In practical applications, when the integrated stove is started, the oil fumes generated during cooking first pass through the opening 701 of the operating platform 7 and are then guided to the air inlet structure. Subsequently, the oil fumes are captured by the grille baffle 201 and the filter screen 202, which filter out large particles of grease and food residues and other impurities in the oil fumes. Then, the oil fumes continue to flow and enter from the air inlet end of the air inlet grille 1. Utilizing the negative pressure effect generated by the gradually narrowing cross-section design of the air inlet grille 1, the oil fumes are accelerated through the air outlet end of the air inlet grille 1 and finally discharged through the air duct system 8.

[0042] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
