Problems solved by technology

[0003] At present, most of the wind rotors used in range hoods are squirrel-cage type. In order to increase the exhaust air volume, the general method is to increase the diameter of the wind rotor, so that the occupied space of the wind rotor will increase, and the volume of the range hood will be further increased accordingly, so that the overall increase in manufacturing costs

Embodiment Construction

[0019] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings, in which the same or similar reference numerals indicate the same or similar elements or elements with the same or similar functions. The embodiments described below with reference to the drawings are exemplary, and are only used to explain the present invention, but should not be construed as limiting the present invention.

[0020] Such as Figure 1 to Figure 4 As shown, an outer ring folding range hood wind wheel described in the present invention includes a circular ring 1, a fan blade 2, a sizing ring 3, a drive plate 4, and a mounting groove 401. The circular ring 1 is provided with a fan blade 2. The sizing ring 3 is fixed on the side of the ring, the installation groove 401 is distributed along the edge of the drive plate 4, and the fan blade 2 is placed in the installation groove 401. The ring 1 includes a top surface 101, an ...

Abstract

The invention relates to an outer-ring-folded type exhaust hood wind wheel comprising a round ring, blades, a shaping ring, a drive plate and installation grooves. The wind blades are arranged on the round ring. The shaping ring is fixed to the side edge of the round ring. The installation grooves are distributed at the edge of the drive plate. The blades are arranged in the installation grooves. The round ring comprises top faces, inclined faces and bottom faces, the bottom faces are located below the top faces, and the bottom faces, the inclined faces and the top faces are integrally formed by bending a plate and are in a toothed ring shape. Each blade is in an arc sheet structure in the manner that the corresponding top face and the corresponding inclined face are jointly stamped. The top end of each blade is connected with the corresponding top face. One end of each blade extends into the circumference defined by the bottom faces. According to the outer-ring-folded type exhaust hood wind wheel, the round ring is in the tooted ring shape, so that the length of each blade is increased; and besides, the diameter of the round ring is constant, and therefore the overall exhaust air rate and the overall rigidity are improved.

Description

Technical field [0001] The invention specifically relates to a wind wheel for a foldable outer ring for range hood, in particular to a wind wheel for a foldable outer ring for range hood. Background technique [0002] In order to quickly and effectively discharge the oil smoke generated during the cooking process to the outside of the existing range hood, the exhaust air volume and wind pressure of the range hood are required to be as large as possible. Among them, the multi-wing centrifugal fan inside the range hood plays an important role, and the performance of the centrifugal fan seriously affects the use effect of the range hood. [0003] At present, most of the wind wheels used in range hoods are squirrel cages. In order to increase the exhaust air volume, the general method is to increase the diameter of the wind wheels to increase the space occupied by the wind wheels. The volume of the range hoods is correspondingly further increased to make the overall Increased manufact...
