Description

Technical Field

[0001] The present invention relates to the technical field of range hood accessories, and specifically refers to an air suction port structure for a range hood. Background Art

[0002] For the range hoods on the market currently, although the air volume at the air outlet is very large, when placing the hand directly in front of the air inlet of the range hood, it is hardly felt that there is air entering the air inlet. The air inlet of the range hood is located at the center of the front panel of the range hood, and this front panel is exactly the air guiding plate of the air source of the range hood. There is a phenomenon in nature that the air near the air guiding plate surface is easily pulled by an external force (near the air guiding plate, due to the design and position of the air guiding plate, different pressure areas will be formed in the air flow. When an external wind force acts, these pressure differences will cause the air to be pulled by the external force). This phenomenon is called the "climbing wind" phenomenon. In this way, the air near the front panel of the range hood is easily sucked into the air inlet of the range hood, while the air directly in front of the air inlet of the range hood is relatively not easily sucked into the air inlet of the range hood. This is the fundamental reason for the poor air suction effect directly in front of the air inlet of the current range hood, resulting in an unsatisfactory oil fume suction effect.

[0003] Currently, although there is a range hood that installs a panel directly in front of the air inlet of the range hood in an attempt to improve the effect of the front air entering, since there is still a large amount of air passing through the front guiding plate into the range hood due to the existence of the air guiding plate of the range hood, and in addition, the newly added panel is not tightly connected to the air inlet of the range hood, therefore, the effect of improving the air inlet directly in front of the air inlet is not ideal. Summary of the Invention

[0004] In order to solve the problems of the prior art, the present invention provides an air suction port structure for a range hood.

[0005] In order to solve the above technical problems, the present invention is realized through the following technical solutions: An air suction port structure for a range hood includes eight plate bodies, namely guiding plate one, guiding plate two, guiding plate three, guiding plate four, guiding plate five, guiding plate six, guiding plate seven, and guiding plate eight;

[0006] The guiding plate one and the guiding plate two have the same structure and size, are triangular, and the guiding plate one and the guiding plate two are symmetrically arranged;

[0007] The guiding plate three, guiding plate four, guiding plate five, guiding plate six, guiding plate seven, and guiding plate eight are sequentially fixed between the guiding plate one and the guiding plate two, thereby forming five air chambers;

[0008] The lower edges of the guiding plate three, guiding plate four, guiding plate five, guiding plate six, and guiding plate seven are not at the same height and are all arc-shaped.

[0009] Further, the third air deflector is located at the edge of the second long side of the first air deflector, the eighth air deflector is located at the edge of the shortest side of the first air deflector, and the length of the eighth air deflector is the same as the length of the shortest side of the first air deflector;

[0010] The upper end of the air suction port structure is a connecting part, and the connecting part is square or rectangular.

[0011] Further, the overall shape of the air suction port structure is a triangular prism, with a large cross-sectional area in the upper part and a small cross-sectional area in the lower part.

[0012] Further, the first air deflector, the third air deflector, the fourth air deflector, the fifth air deflector, the sixth air deflector, the seventh air deflector, and the eighth air deflector have different sizes.

[0013] Further, the first air deflector, the second air deflector, the third air deflector, the fourth air deflector, the fifth air deflector, the sixth air deflector, the seventh air deflector, and the eighth air deflector are all made of metal plates.

[0014] The advantages of the present invention compared with the prior art are as follows:

[0015] 1. By using the principle that the air near the air deflector surface is easily pulled by an external force, all eight plate bodies of the air suction port structure serve as air deflectors, thus greatly improving the air suction effect and enhancing the oil fume inhalation efficiency;

[0016] 2. The eight plate bodies form five air chambers, increasing the air suction capacity of the air suction port of the air suction port structure, thereby enhancing the air suction effect. There is a negative pressure area at the air suction port of the air suction port structure, further increasing the air suction effect;

[0017] 3. The overall shape is a triangular prism, with a large cross-sectional area in the upper part and a small cross-sectional area in the lower part. In this way, the space between the range hood and the stove wall can be fully utilized, enabling the position of the air suction port structure to be moved down as much as possible, getting closer to the stove, and further enhancing the air suction effect;

[0018] 4. The structure is simple, facilitating production and manufacturing. Made of metal plates, it has a low cost and is not easily damaged. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. Generally, the components of the embodiments of the present invention described and shown in the accompanying drawings here can be arranged and designed in various different configurations.

[0026] Embodiment 1, in combination with the attached Figures 1-4 , an air suction port structure for an oil fume extractor, includes eight plate bodies, namely the first air guide plate 1, the second air guide plate 2, the third air guide plate 3, the fourth air guide plate 4, the fifth air guide plate 5, the sixth air guide plate 6, the seventh air guide plate 7, and the eighth air guide plate 8;

[0027] The first air guide plate 1 and the second air guide plate 2 have the same structure and size, are triangular, and are symmetrically arranged;

[0028] The third air guide plate 3, the fourth air guide plate 4, the fifth air guide plate 5, the sixth air guide plate 6, the seventh air guide plate 7, and the eighth air guide plate 8 are successively fixed between the first air guide plate 1 and the second air guide plate 2, thus forming five air chambers 9. The function of the air chamber 9 is to increase the air suction capacity of the air suction port of the air suction port structure, thereby increasing the air suction effect;

[0029] The lower edges of the third air guide plate 3, the fourth air guide plate 4, the fifth air guide plate 5, the sixth air guide plate 6, and the seventh air guide plate 7 are not at the same height and are all arc-shaped. In this way, a space, that is, a negative pressure area, is formed at the air suction port of the air suction port structure. The gas in this space will all be sucked into the air suction port. The cross-section of this space is small, making the sucked gas very concentrated, and further increasing the air suction effect.

[0030] The air suction port structure is divided into upper and lower parts. The upper part serves as a duct. The upper end of the air suction port structure is tightly connected to the air inlet of the oil fume extractor through bolts and is detachable, which is convenient for cleaning the air suction port structure.

[0031] When the present invention is specifically implemented, the air mixed with oil fume in front of the air inlet of the oil fume extractor enters through the air suction port of the air suction port structure, enters the air inlet of the oil fume extractor through the air outlet of the air suction port structure, and then is discharged through the air outlet of the oil fume extractor.

[0032] In this specific embodiment, the third air deflector 3 is located at the edge of the second long side of the first air deflector 1, and the eighth air deflector 8 is located at the edge of the shortest side of the first air deflector 1. The length of the eighth air deflector 8 is the same as the length of the shortest side of the first air deflector 1. The overall shape of the air suction port structure is a triangular prism, with a large cross-sectional area at the upper part and a small cross-sectional area at the lower part. In this way, the space between the range hood and the stove wall can be fully utilized, and the position of the air suction port structure can be moved down as much as possible to be closer to the stove, further enhancing the air suction effect.

[0033] The upper end of the air suction port structure is a connecting part, which is square or rectangular. It not only plays a role in connecting the air deflectors to each other, but also seals the connection between the connecting part and the square air inlet of the range hood, and further ensures that all the air inhaled by the range hood enters from the air suction port of the air suction port structure.

[0034] In this specific embodiment, the first air deflector 1, the third air deflector 3, the fourth air deflector 4, the fifth air deflector 5, the sixth air deflector 6, the seventh air deflector 7, and the eighth air deflector 8 have different sizes.

[0035] In this specific embodiment, the first air deflector 1, the second air deflector 2, the third air deflector 3, the fourth air deflector 4, the fifth air deflector 5, the sixth air deflector 6, the seventh air deflector 7, and the eighth air deflector 8 are all made of metal plates, which are not easily damaged and have a long service life.

It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention. In addition, terms such as "first", "second", "third", etc. are only used for descriptive distinction and cannot be understood as indicating or implying relative importance.

[0037] In addition, if terms such as "horizontal", "vertical", "hanging" are used, it does not mean that the component is required to be absolutely horizontal or hanging, but can be slightly inclined. For example, "horizontal" only means that its direction is more horizontal relative to "vertical", and does not mean that the structure must be completely horizontal, but can be slightly inclined.

[0038] In the description of the embodiments of the present invention, "a plurality of" represents at least 2.

[0039] In the description of the embodiments of the present invention, it should also be noted that unless otherwise clearly specified and defined, the terms "set", "installed", "connected", and "connected" should be understood in a broad sense.
