Description

Technical Field

[0001] The utility model relates to kitchen ventilation and smoke exhaust equipment, in particular to a range hood. Background Art

[0002] In the prior art, common open range hoods include the following structures: the first structure, such as the suction panel disclosed in CN212615441U, is a slanted structure; the second structure, such as the suction panel disclosed in CN220453747U, is a "7"-shaped structure; the third structure, such as the suction panel disclosed in CN207438688U, is a planar structure, etc. These open range hoods have a common disadvantage that the oil fume suction effect is better in the middle of the suction panel, but the four corners have serious air leakage, especially the four corners close to the user end have serious air leakage, resulting in poor oil fume suction effect. Utility Model Content

[0003] In order to overcome the deficiencies of the prior art, the utility model provides a range hood with side suction.

[0004] The technical solution adopted by the utility model to solve its technical problems is:

[0005] A range hood with side suction comprises a box body, the box body having a longitudinal portion and a transverse portion located at the upper end of the longitudinal portion and extending forward, the longitudinal portion and / or the transverse portion being provided with a main suction port; side boxes extending forward are provided on both sides of the longitudinal portion, the interior of the side boxes being connected to the interior of the box body; and side suction ports are provided on the inner side of the side boxes.

[0006] As a further improvement of the present invention, the side air intake is located near the front edge of the side box body.

[0007] As a further improvement of the present invention, the opening direction of the side air suction port is perpendicular to the opening direction of the main air suction port.

[0008] As a further improvement of the present invention, the side air suction ports extend longitudinally along the inner side of the side box body and / or are arranged at longitudinal intervals.

[0009] As a further improvement of the present invention, a side suction fan is provided in the side suction port.

[0010] As a further improvement of the present invention, the inner side wall of the transverse portion is provided with a top suction port.

[0011] As a further improvement of the present invention, the front side and left and right edges of the transverse portion have downwardly protruding windshields. The inner side of the windshield is provided with a concave return air duct, the return air duct having an air inlet side and an air outlet side. The inner side of the windshield is provided with a concave return air duct, and the angle formed by the tangent line of the edge of the air outlet side and the transverse portion is an acute angle.

[0012] The beneficial effects of the present invention are as follows: the present invention is provided with side boxes on both sides of the longitudinal part, and side air suction ports are provided on the inner sides of the side boxes. The longitudinal part, the transverse part and the side boxes constitute an oil fume absorption space of a semi-enclosed structure. Most of the oil fume is sucked into the box through the main air suction port. While the oil fume diffused outwards on both sides is inhaled into the side air suction ports, since the side air suction ports are located near the front edges of the side boxes, the external air will draw the oil fume diffused outwards on both sides into the oil fume absorption space again, which can reduce the leakage of side oil fume and effectively improve the oil fume absorption effect.

[0013] In addition, the utility model is provided with a downwardly protruding wind shield on the front side and left and right side edges of the horizontal part, and a return air duct is provided on the inner side of the wind shield. The airflow flowing outward from the upper side is guided by the return air duct and flows back to the oil fume suction space again. Since the return air duct has an air inlet side and an air outlet side, the greater the airflow flowing on the air inlet side, the faster the flow rate leaving the air outlet side. At this time, the external air around the edge of the air outlet side will also be driven into the oil fume suction space. The inhaled external air forms a shielding wind curtain, which can further reduce oil fume leakage. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] In order to make the purpose, technical solution and advantages of the present invention more clear, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be noted that the embodiments of the present invention and the features therein can be combined with each other unless there is any conflict.

[0023] It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the present invention.

[0024] Some embodiments of the present invention are described below with reference to the accompanying drawings.

[0025] Reference Figures 1 to 5 A range hood with side suction comprises a housing 1, a main fan 13 disposed within the housing 1, the housing 1 having a longitudinal portion 11 and a transverse portion 12 located at the upper end of the longitudinal portion 11 and extending forward, the longitudinal portion 11 and / or the transverse portion 12 being provided with a main suction port 2; side housings 3 extending forward are provided on both sides of the longitudinal portion 11, the interiors of the side housings 3 being in communication with the interior of the housing 1; and side suction ports 31 are provided on the inner sides of the side housings 3. The side suction ports 31 are located near the front edge of the side housings 3. In the present invention, the longitudinal portion 11, the transverse portion 12 and the side box body 3 constitute a semi-enclosed structure for extracting oil smoke. Most of the oil smoke is sucked into the box body 1 through the main air intake port 2. The oil smoke diffused outward on both sides is sucked into the side air intake port 31. At the same time, since the side air intake port 31 is located near the front edge of the side box body 3, the external air around the edge of the side box body 3 is also driven into the side air intake port 31. The external air will draw the oil smoke diffused outward on both sides into the oil smoke extraction space again, which can reduce the leakage of side oil smoke and effectively improve the oil smoke extraction effect.

[0026] As a further improvement of the present invention, the opening direction of the side air inlet 31 is perpendicular to the opening direction of the main air inlet 2. The oil smoke diffused outward on both sides can be sucked into the side air inlet 31, thereby improving the oil smoke suction effect.

[0027] As a further improvement of the present invention, the side air intakes 31 extend longitudinally along the inner side of the side box body 3 and / or are arranged longitudinally at intervals. The side air intakes 31 can be shaped in various styles, such as a strip, a square, a cone, a circle, or an ellipse. For example, the side air intakes 31 can be longitudinally extending strips or longitudinally spaced circles. The structure of the side air intakes 31 can be flexibly configured as needed.

[0028] As a further improvement of the present invention, a side suction fan is provided in the side suction port 31. The suction power of the side suction port 31 can come from the main fan 13 or from the side suction fan. Specifically, the side suction fan can be provided in the side suction port 31 or not, and can be flexibly set according to needs.

[0029] The front side of the side box body 3 can be extended vertically or inclined outward from bottom to top. In this embodiment, it is best that the front side of the side box body 3 is inclined outward from bottom to top, so that the space occupied by the lower side of the box body 1 is reduced, thereby increasing the user's operating space and facilitating use.

[0030] In the present invention, the side box 3 and the housing 1 can be integrally formed or assembled separately. Compared to an integrally formed structure, this reduces assembly difficulty and improves production efficiency. Compared to a separate assembly structure, the side box 3 can be installed on range hoods of any structure by simply connecting the interior of the side box 3 to the interior of the housing 1. This allows for upgrading existing range hoods, reducing production costs, and allows the side box 3 to be extended forward to a desired position according to customer needs.

[0031] Reference Figure 6 and Figure 7 The inner side wall of the transverse portion 12 is provided with a top suction port 14. The top suction port 14 can be provided in the middle of the inner side of the transverse portion 12 or in the inner side edge of the transverse portion 12. In this embodiment, the top suction port 14 is arranged at intervals along the inner side edge of the transverse portion 12 in the circumferential direction. The oil smoke flowing outward from the upper side will flow into the top suction port 14 of the transverse portion 12, which can further reduce oil smoke leakage.

[0032] As a further improvement of the present invention, the front side and left and right edges of the transverse portion 12 have a downwardly protruding windshield 4. The inner side of the windshield 4 is provided with a concave return air duct 41, and the return air duct 41 has an air inlet side 42 and an air outlet side 43. The inner side of the windshield 4 is provided with a concave return air duct 41, and the angle formed by the edge tangent of the air outlet side 43 and the transverse portion 12 is an acute angle a. In the present invention, the airflow flowing outward from the upper side is guided by the return air duct 41 and will flow back to the oil fume suction space again. Since the return air duct 41 has an air inlet side 42 and an air outlet side 43, the greater the airflow flowing on the air inlet side 42, the faster the flow rate leaving the air outlet side 43. At this time, the external air around the edge of the air outlet side 43 will also be driven into the oil fume suction space. The inhaled external air forms a layer of shielding wind curtain, which can further reduce oil fume leakage.
