[0021] The utility model provides the following description of the drawings to help comprehensively understand various embodiments of the utility model as defined by the claims and their equivalents. The description includes various specific details to help understanding, but these details should be regarded as just exemplary. Therefore, those skilled in the art will realize that various changes and modifications can be made to various embodiments described herein without departing from the scope and spirit of the utility model.

[0022] In the description of the utility model, the orientation description, such as the orientation or positional relation of the indication of up, down, front, back, left, right etc. for the orientation or positional relation shown in the drawing, is only for the convenience of describing the utility model and simplifying the description, and is not to indicate or imply that the indicated device or element must have a particular orientation, be constructed and operated in a particular orientation, and therefore can not be understood as limiting the utility model.

[0023] It should be understood that when an element (e.g., a first element) is "connected" with another element (e.g., a second element), the element can be directly connected with the other element, or there can be intervening elements (e.g., a third element) between the element and the other element.

[0024] The embodiment of the utility model provides a kind of top suction and side suction type range hood of four around air intake, as shown in Figs. 1-3 The utility model discloses a kind of top suction and side suction type range hood, as shown in

[0025] The front side of side suction part 200 is provided with first air inlet 201, when range hood works, part of oil fume enters into the smoke collecting hood through first air inlet 201, another part of oil fume with faster speed will rise upwards.

[0026] The bottom surface of top suction part 100 is provided with concave groove 110, and the side wall 111 of concave groove 110 is provided with a plurality of second air inlets 101.For the part of oil fume rising upwards, it will enter into concave groove 110 after rising upwards, and the side wall 111 of concave groove 110 plays a role in blocking the diffusion of oil fume, and this part of oil fume will enter into the smoke collecting hood through second air inlet 101, which can reduce the escape of oil fume and improve the adsorption effect of oil fume.

[0027] In some embodiments, the side wall 111 of the concave groove 110 is inclinedly arranged relative to the bottom wall 112 of the concave groove 110, and in a direction perpendicular to the bottom wall 112 of the concave groove 110 and pointing to the outside of the concave groove 110, the side wall 111 of the concave groove 110 gradually moves away from the bottom wall 112 of the concave groove 110.

[0028] This structure makes the opening of concave groove 110 expand, so that more oil fume can enter into concave groove 110, improve the adsorption effect of oil fume, at the same time, also expand the area of the side wall 111 of concave groove 110, so that more second air inlets 101 can be arranged on the side wall 111 of concave groove 110, which can further reduce the escape of oil fume and improve the adsorption effect of oil fume.

[0029] In some embodiments, the recess 110 is generally a square groove, the side wall 111 of the recess 110 includes a front side wall located at the front side, a rear side wall located at the rear side, a left side wall located at the left side, and a right side wall located at the right side, and the second air inlet 101 is arranged on each of the front side wall, the rear side wall, the left side wall and the right side wall. The structure of the recess 110 is roughly similar to the shape of the bottom surface of the top suction part 110, compared with other shapes, the distance from the recess 110 to the edge of the bottom surface of the top suction part 110 can be reduced, and the area of the recess 110 is enlarged as much as possible, so that more oil fume can enter the recess 110. At the same time, the four side walls of the recess 110 are provided with the second air inlet 101, and when the oil fume moves to any side wall, it can enter the smoke hood through the second air inlet 101 of the side wall, which further improves the adsorption effect of the oil fume.

[0030] In some embodiments, the inner wall of the top suction part 100 is provided with a protruding blocking ring 102 around the second air inlet 101. For the oil liquid attached to the inner wall of the top suction part 100, the blocking ring 102 blocks the flow of the oil liquid to the second air inlet 101, so that the oil liquid attached to the inner wall of the top suction part 100 is not easy to drip down through the second air inlet 101, which can reduce the pollution to the cooking bench.

[0031] In some embodiments, the top suction part 100 includes a bottom plate 120 located at the bottom thereof, the recess 110 is arranged on the bottom surface of the bottom plate 120, and the second air inlet 101 of the above-mentioned embodiments penetrates the bottom plate 120, and the blocking ring 102 of the above-mentioned embodiments is arranged on the top surface of the bottom plate 120.

[0032] Further, the side suction part 200 includes a front baffle 210 located at the front side thereof, the rear side of the bottom plate 120 is connected with a downwardly bent butt plate 130, the upper end of the front baffle 210 abuts against the lower end of the butt plate 130, and the first air inlet 201 is arranged below the front baffle 210. This can reduce the components of the top suction part 100 and the side suction part 200, and facilitate overall assembly.

[0033] In the present embodiment, the butt plate 130 can be arc-shaped and bent, which is more smooth in transition and can guide part of the oil fume to flow to the recess 110. The butt plate 130 and the bottom plate 120 can be integrally formed, which facilitates overall manufacturing and can also strengthen the connection strength of the butt plate 130 and the bottom plate 120.

[0034] Still further, the side suction part 200 further includes a flow guide seat 220 located at the bottom thereof, the flow guide seat 220 has an inclined flow guide surface 221, and the height of the flow guide surface 221 gradually increases in the direction of extending rearward; the first air inlet 201 is located between the flow guide surface 221 and the front baffle 210.

[0035] When the oil fume enters the side suction part 200 from the first air inlet 201, the flow guide surface 221 can guide the oil fume to flow upwards, which can improve the flow speed of the airflow, so as to improve the adsorption effect of the oil fume.

[0036] Furthermore, the bottom of the flow guide seat 220 is fixed with an oil cup 230, and the lower end of the flow guide surface 221 is located directly above the oil cup 230. The oil liquid can flow downwards along the flow guide surface 221 and finally drip into the oil cup 230, which can avoid the accumulation of the oil liquid on the flow guide seat 220.

[0037] The terms and words used in the above description and claims are not limited by the literal meaning, but are merely used by the applicant to enable a clear and consistent understanding of the present application. Therefore, it should be clear to those skilled in the art that the above description of various embodiments of the present application is provided only for illustration, not for limitation, of the present application as defined by the appended claims and their equivalents.
