Embodiment 1

[0046] see Figure 1 to Figure 5 , a range hood, including an upper box body 1, a middle box body 2, a box body structure composed of 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 larger than the fan frame 4 . The upper box 1 , the middle box 2 and the lower box 3 are all hollow boxes. The bottom of the rear side 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 top of the rear side of the lower box 3, and between the upper box 1 and the middle box 2, the middle box 2 and the lower casing 3 are in fluid communication with each other, and the upper casing 1 and the fan frame 4 are in fluid communication. The size of the upper box 1 and the lower box 3 in the front-rear direction is larger than that of the middle box 2, and the middle box 2 is a box with a thin structure in the front-rear direction, that is...

Embodiment 2

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

Embodiment 3

[0073] see Figure 20 In this embodiment, the difference from the second embodiment above is that the filter portion 6112 occupies 3 / 4 in the circumferential direction, while the non-filtering portion 6113 occupies 1 / 4 in 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 energy of a fluid (gas, liquid or a mixture of the two) From the first part to flow along the flow path or / and to be transported to the second part, the first part and the second part can be directly connected, or the first part and the second part can pass through At least one third party is in indirect communication, which may be a fluid channel such as a pipe, channel, conduit, flow guide, hole, slot, etc., or a chamber that allows fluid to flow therethrough, or a combination there...

Abstract

The invention discloses a range hood, comprising a box body structure and a fan frame for setting a fan system. The box body structure is arranged below the fan frame, and an air inlet is opened at the bottom of the box body structure. An oil fume airflow channel is formed between the air inlet and the fan frame, and it is characterized in that: a filter is arranged in the box structure, and the filter is in the form of a hollow column, so that the oil fume airflow enters the filter from the peripheral wall and flows from the axial direction to the filter. The end is discharged, and the filter is divided into a filter part for supplying the oil fume flow and a non-filter part for blocking the oil fume flow along the circumferential direction. The filter can rotatably change the ventilation area of ​​the filter part toward the oil fume flow. Compared with the prior art, the present invention has the advantages that: by dividing the filter into a filtering part and a non-filtering part in the circumferential direction, the passing air volume can be adjusted by rotation, thereby meeting different actual requirements and improving the effect of absorbing oil fume.

Description

technical field [0001] The invention relates to a lampblack purification device, in particular to a lampblack machine. Background technique [0002] Chinese cooking will produce a lot of oil fumes. In order to keep the kitchen environment clean and human health, range hoods have become one of the indispensable kitchen appliances in modern families. Generally, range hoods include top suction and side suction, and top suction range hoods are more and more widely used due to their neatness and lightness, small footprint, good match with hanging cabinets, and low noise. [0003] The top suction range hood usually includes a fume collecting hood and a fan frame located on the fume collecting hood. A volute, an impeller and a motor that drives the impeller are installed in the fan frame. The center of the fume collecting hood is provided with an air inlet and a height where the fan is located. The negative pressure area is directly connected, and this type of range hood is equipp...
