Three-dimensional noise reduction integrated stove

Abstract

The invention discloses a three-dimensional noise reduction integrated stove, and relates to the field of integrated stoves. At present, in order to improve the smoke suction effect, an integrated stove generally adopts a fan with large air volume, the noise of the fan is large, and a poor experience feeling is brought about to consumers. The three-dimensional noise reduction integrated stove comprises a volute, an impeller arranged in the volute and a motor used for driving the impeller. The volute comprises a volute front plate, a volute rear plate and a volute side plate arranged between the volute front plate and the volute rear plate. The inner side contour line of the volute side plate forms a volute molded line, a plurality of first through holes are formed in the volute side plate, and a first sound absorption layer opposite to the first through holes is arranged on the periphery of the volute side plate. An air inlet is formed in the volute rear plate. The distances between the adjacent first through holes are larger than or equal to two kinds, and thus multiple through hole rates of the volute side plate are formed. Moreover, the noise reduction assembly forms a semi-encirclement ring, and noise reduction treatment is conducted on the three side walls except the rear side wall of a fan box. And the fan assembly is enveloped in multiple directions, so that the noise of the fan assembly is effectively reduced.

Description

technical field [0001] The invention relates to the field of integrated stoves, in particular to an integrated stove with three-dimensional noise reduction. Background technique [0002] The fan is one of the main parts of the integrated stove. It has the function of sucking and exhausting kitchen fume. The power of the fan drives the impeller to rotate, so that the fume passing through the smoke inlet is sucked into the inner wheel, and then passes through the exhaust port of the fan and The smoke pipe is exhausted to the outside, thus providing users with cleaner kitchen indoor air. At present, in order to improve the smoking effect of integrated stoves, fans with large air volume are usually used to suck and exhaust kitchen fumes. come with certain health risks. To solve this problem, such as figure 1 As shown, some integrated stoves use sound-absorbing components to cover the side wall of the volute of the fan, and use sheet metal parts to fix the sound-absorbing comp...

Problems solved by technology

At present, in order to improve the smoking effect of integrated stoves, fans with large air volume are usually used to suck and exhaust kitchen fumes. certain health risks

To solve this problem, such as figure 1 As shown, some integrated stoves use sound-absorbing components to cover the side wall of the volute of the fan, and use sheet metal parts to fix the sound-absorbing components to achieve noise reduction. The sound-absorbing components use equidistant noise reduction holes. Equally spaced noise reduction holes can only absorb and reduce noise in a certain frequency range in terms of noise reduction, while the noise frequency range in the fan is relatively wide, so setting equally spaced holes makes the overall sound absorption effect limited, thereby lead to poor noise reduction

Moreover, the fan is only equipped with sound-absorbing components in the radial direction, so the noise reduction effect in the radial direction is obvious, but there is no noise reduction effect in the axial direction, resulting in a relatively large noise of the whole machine
