Embodiment 1

[0046] see Figure 1 to Figure 5 , a range hood, comprising a box structure consisting of an upper box body 1, a middle box body 2, and a lower box body 3, and a fan frame 4, the upper box body 1 is arranged directly below the fan frame 4, and its The length in the left-right direction is greater than the fan frame 4 . The upper box body 1, the middle box body 2 and the lower box body 3 are all hollow boxes. The rear bottom of the upper box 1 is connected to the top of the middle box 2, the bottom of the middle box 2 is connected to the rear top of the lower box 3, and between the upper box 1 and the middle box 2, the middle box 2 and the lower box body 3 are in fluid communication with each other, and the upper box body 1 and the fan frame 4 are in fluid communication. The size of the upper box body 1 and the lower box body 3 in the front-back direction is larger than that of the middle box body 2, and the middle box body 2 is a box body with a thin structure in the front-b...

Embodiment 2

[0066] see Figure 19 , in this embodiment, the difference from the first embodiment above is that a self-cleaning device is added outside the first filter 61 and the second filter 62, including a partition 71, a heater 72, a water pump 73 and a nozzle 74. Wherein, there are three partitions 71, respectively connected between the top front side of each filter and the top wall 31 of the lower box 3 (or the front side of the transition box 22), and the top rear side of each filter and between the rear side wall 34 (or the rear side of the transition case 22) of the lower case 3 and between the front and rear sides of the transition case 22, so that the top of each filter forms a fourth chamber Q4 for drying Dry. A third chamber Q3 is formed between each filter and the bottom wall 32 and rear side wall 34 of the lower box body 3 for cleaning. The above-mentioned heater 72 is arranged on the top of the fourth chamber Q4, that is, on the side of the uppermost partition 71 facing...

Embodiment 3

[0073] see Figure 20 In this embodiment, the difference from the second embodiment above is that the filter part 6112 occupies 3 / 4 of the circumferential direction, while the non-filter part 6113 occupies 1 / 4 of the circumferential direction.

[0074] The "fluid communication" referred to in the present invention refers to the spatial positional relationship between two parts or parts (hereinafter collectively referred to as the first part and the second part respectively), that is, the fluid (gas, liquid or a mixture of both) can Flow or / and be transported from the first position to the second position along the flow path, it may be that the first position and the second position are directly connected, or the first position and the second position may be passed through At least one third party communicates indirectly, and the third party may be a fluid channel such as a pipe, channel, conduit, flow guide, hole, groove, etc., or a chamber allowing fluid to flow through, or a...

Abstract

The invention discloses a range hood which comprises a box body structure and a fan frame used for arranging a fan system. The box body structure is arranged below the fan frame, an air inlet is formed at the bottom of the box body structure, and a lampblack airflow channel is formed between the air inlet and the fan frame. The range hood is characterized in that a filter is mounted in the box body structure, the filter is in a hollow column shape, so that lampblack airflow enters the filter from the peripheral wall and is discharged from the axial end part, the filter is divided into a filtering part for the lampblack airflow to pass through and a non-filtering part for preventing the lampblack airflow from passing through along the peripheral direction, and the filter can rotatably change the ventilation area of the filtering part towards the lampblack airflow. Compared with the prior art, the range hood has the advantages that the filter is divided into the filtering part and the non-filtering part in the circumferential direction, and the passing air volume can be adjusted through rotation, so that different actual requirements are met, and the lampblack suction effect is improved.

Description

technical field [0001] The invention relates to a cooking fume purifying device, in particular to a range hood. Background technique [0002] Chinese cooking will produce a lot of oil fumes. In order to keep the kitchen environment clean and the human body healthy, range hoods have become one of the indispensable kitchen appliances in modern families. Generally, range hoods include top-suction and side-suction types, and top-suction range hoods are more and more widely used because of their neatness, lightness, small footprint, good matching with wall cabinets, and low noise. [0003] The top suction range hood usually includes a smoke collection hood and a fan frame located on the smoke collection hood. A volute, an impeller and a motor for driving the impeller are installed in the fan frame. The negative pressure area is directly connected, and this type of range hood is equipped with a filter at the air inlet. When the oil fume passes through the filter, it will be parti...
