Smoke exhausting device

Abstract

The invention discloses a smoke exhausting device which comprises a fan assembly and a smoke collecting hood, wherein the fan assembly comprises a fan and a fan shell; the fan is arranged in the fan shell; the fan is vertically placed; the fan shell has only a first smoke inlet opening facing backwards; the smoke collecting hood is arranged below the fan assembly; the smoke collecting hood is provided with a second smoke inlet and a second smoke outlet; the second smoke inlet faces downwards; the second smoke outlet is communicated with the first smoke inlet, wherein the smoke collecting hoodcomprises a flow deflector; the flow deflector is located above the second smoke inlet and extends obliquely upward from the front to the rear. Therefore, the fan assembly is matched with the smoke collecting hood to reduce loss of pneumatic resistance of the smoke exhausting device, improve smoke sucking efficiency of the smoke exhausting device, also reduce noise during work of the smoke exhausting device to improve satisfaction degree of users; moreover, the smoke exhausting device can also achieve an effect of zero smoke leakage.

Description

technical field [0001] The invention relates to the technical field of smoke exhaust, in particular to a smoke exhaust device. Background technique [0002] At present, range hoods have basically entered a state of popularization in the market, and the demand for range hoods in key cities is developing towards high-end, personalized and intelligent development. The main key components that affect the actual effect of range hoods include fans, air ducts, suction inlet structures, etc. Among them, the layout of fans in different installation positions, as well as the requirements for the appearance and manufacturing process of the flow channel structure and shape, lead to air flow during the flow process. Inevitably, there is an uneven distribution state, which affects the distribution of velocity and pressure, and then leads to an uneven distribution state of the flow field near the suction port of the range hood, which is not conducive to the effect of the range hood.

The main key components that affect the actual effect of range hoods include fans, air ducts, suction inlet structures, etc. Among them, the layout of fans in different installation positions, as well as the requirements for the appearance and manufacturing process of the flow channel structure and shape, lead to air flow during the flow process. There is inevitably an uneven distribution state, which affects the distribution of velocity and pressure, and then leads to an uneven distribution state of the flow field near the suction port of the range hood, which is not conducive to the effect of the range hood

[0003] In addition, in order to obtain a better fume extraction effect, range hoods on the market are increasingly developing towards large air volume and high back pressure, so as to increase the negative pressure coverage of the range hood. However, the noise level of range hoods and The air volume is directly related, the greater the air volume, the greater the noise, and the worse the user experience

[0004] There are various types of smoking hoods currently on the market, which can be roughly divided into top-suction type, near-suction type, integrated type, etc. according to the structural form. The depth of the whole machine is about 515mm, and it is easy to bump into each other during cooking, which affects the user experience

[0005] Although the depth of the near-suction hood is less than 500mm, in order to make up for the lack of smoke collection area at the top, the slope on the lower side is closer to the cooking utensils, occupying the cooking space and also affecting the user experience.

[0006] For the integrated range hood, although the structure is compact, it will not occupy the cooking space, but it is difficult to achieve zero leakage of oil fume under the state of stir-frying. To improve the smoking efficiency, it will not only bring about the problem of increased noise, but also the excessive air volume will increase the consumption of gas
