Embodiment 1

[0035] see Figure 1 ~ Figure 3 , a range hood, comprising a smoke collection hood 1, a chassis 2 arranged above the fume collection hood 1, a fan system 4 is arranged in the chassis 2. An air inlet 11 is provided on the fume collecting hood 1, so that the fan system 4 in the cabinet 2 can suck oily fume into the cabinet 2 through the air inlet 11 and discharge it to the public flue.

[0036] An air duct 25 is formed in the cabinet, and the air duct 25 is preferably gradually narrowed from bottom to top.

[0037] The fan system 4 in the cabinet 2 adopts a ternary fan, which can adopt the existing technology, such as the fan structure disclosed in the patent of the applicant whose application number is 201620102790.9. It is used to discharge the oil fume discharged from the fan system 4 to the air outlet duct. The specific structure of the blower system 4 will be described in detail below.

[0038] The range hood also includes a fume filter device. In this embodiment, two fi...

Embodiment 2

[0063] see Figure 10 and Figure 11 , in this embodiment, the difference from the above-mentioned first embodiment is that the first three-way fan 41 and the second three-way fan 42 share the same volute 44, that is, the first three-way fan of the first three-way fan 41 The impeller 412 and the second three-dimensional impeller 422 of the second three-dimensional blower 42 are both arranged in the same volute 44 .

[0064] A mounting plate 45 is arranged between the two ternary impellers, thereby separating the two ternary impellers on both sides of the mounting plate 45, and the mounting plate 45 extends to the top of the volute 44, thereby dividing the volute 44 into two The first oil fume passage 441 and the second oil fume passage 442 are independent. The driving motor 43 passes through the mounting plate 45 and is connected and fixed with the mounting plate 45 .

[0065] In this embodiment, the air outlet cover 5 only includes a cover body 51 and a deflector 56 arrang...

Abstract

The invention discloses a range hood. The range hood comprises an exhaust fume collecting hood, a machine box and an oil fume filtering device. The machine box is arranged on the top of the exhaust fume collecting hood. An air inlet is formed in the exhaust fume collecting hood. An air channel is formed in the machine box. The oil fume filtering device comprises an oil screen, wherein the oil screen is arranged in the air inlet. The whole oil screen is in a shape of a big-end-up cone which downwards extends from the air inlet. A fan system is arranged in the machine box and comprises a first ternary fan and a second ternary fan, wherein the first ternary fan and the second ternary fan are arranged in parallel. The oil fume filtering device further comprises a rotary filtering screen, wherein the rotary filtering screen is arranged in the machine box and located in an inlet of the air channel. The oil screen and the rotary filtering screen are arranged, the oil screen can conduct rectification and guide on the airflow, the rotary filtering screen facilitates the purpose that the airflow is uniformly distributed in the air inlet, and therefore oil fumes which enter the air channel can enter corresponding air inlet cavities of the corresponding fans, the gas independently flows in each air inlet cavity, the phenomenon that air inlets of the two adjacent fans seize the air is avoided, and then the air quantities in the air inlets of the double fans can be uniform.

Description

technical field [0001] The invention relates to kitchen appliances, in particular to a range hood. Background technique [0002] Range hoods have become one of the indispensable kitchen appliances in modern families. Generally, range hoods include top-suction and near-suction types. Top-suction range hoods use the principle of rising hot air to absorb and discharge the naturally rising oil fumes generated during cooking. It has more and more widespread applications. [0003] The oil fume filter device is an important component of the range hood, and the technical improvement of the oil fume filter device has always been a technical hotspot in the range hood field. Existing range hoods are equipped with filter screens for the purpose of collecting oil fumes and dust generated during cooking, such as a range hood disclosed in Chinese Patent Application No. As well as the box and the fan assembly, the oil receiving box is set under the oil filter screen, and the oil fume is ...
