Embodiment Construction

[0054] 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 only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0055] It should be noted that if there is a directional indication (such as up, down, left, right, front, back...) in the embodiment of the present invention, the directional indication is only used to explain that it is in a specific posture (as shown in the drawings). If the specific posture changes, the relative positional relationship, movement, etc. of the components below will also change the directional indication accordingly.

Abstract

The invention discloses a range hood, which comprises a casing, a diversion structure, a fan system and a plurality of condensation plates, wherein the casing and the diversion structure define a cavity, and the fan system is arranged in the cavity; a plurality of smoke collecting chambers are formed in one side, away from the fan system, of the diversion structure, and air inlet structures are arranged on the inner wall surfaces of the smoke collecting chambers; the plurality of condensation plates are arranged on the side, away from the fan system, of the diversion structure and correspond to at least two smoke collecting chambers; negative pressure flow passages are formed between the condensation plates and the inner wall surfaces of the corresponding smoke collecting chambers, and arecommunicated with the corresponding air inlet structures; the cross sections of the negative pressure flow passages is tapered from the inside of the inlets, and the condensation plates are movably set to adjust the size of the corresponding negative pressure flow passage inlets. The condensation plates of the range hood are movably arranged to adjust the sizes of the corresponding negative pressure flow passage inlets, so as to maintain a better effect of smoke sucking and exhausting in an application scenario with a wide smoke range and a large amount of smoke.

Description

Technical field [0001] The invention relates to the technical field of kitchen appliances, in particular to a range hood. Background technique [0002] The ability of the range hood to suck and exhaust the range hood is the core capability of the range hood. After increasing the air volume and air pressure of the range hood, the range hood's range hood can be improved to a certain extent. However, in addition to air volume and pressure, a good air intake layout will also affect the smoking effect of the range hood. In the case of bottlenecks in the increase of air volume and air pressure and the optimization of noise, a good aerodynamic layout can better ensure the smoking performance of the hood. [0003] In order to adapt to operating scenarios with a wide range of smoke and a large amount of smoke such as double stoves, the existing technology generally adopts increasing the outer size of the diversion structure and / or adding a condenser plate. However, this method has greate...
